| ○ | ○ | Article | A Latent Class Analysis of Suicidal Behaviors in Adolescents | Objective The purpose of the present study was to identify adolescents' suicide subgroups using five indicators (depression, anxiety, suicide ideation, and planned and attempted suicide), and explore the distinctive features of each subgroup.Methods This study included 2,258 teenagers from four schools. Both adolescents and their parents, who voluntarily agreed to participate in the study, completed a series of self-reported questionnaires on depression, anxiety, suicide, self-harm, self-esteem, impulsivity, childhood maltreatment, and deviant behaviors. The data were analyzed using latent class analysis, a person-centered method. Results Four classes were detected: "high risk for suicide without distress," "high risk for suicide with distress," "low risk for suicide with distress," and "healthy." The "high risk for suicide with distress" class was the most severe on all evaluated psychosocial risk factors, namely, impulsivity, low self-esteem, self-harming behaviours, deviant behaviour problems, and childhood maltreatment, followed by "high risk Conclusion This study identified two high risk subgroups for adolescent' suicidality, "high risk for suicide with or without distress." Both high risk subgroups for suicide showed higher scores for all psychosocial risk factors than low risk subgroups for suicide. Our findings suggest that special attention needs to be paid to the latent class "high risk for suicide without distress," as this group's "cry for help" might be relatively difficult to detect. Specific interventions for each group (e.g., distress safety plans for "suicidal potential with or without emotional distress") need to be developed and implemented.

| ○ | ○ | Article | Attachment Insecurity and Stigma as Predictors of Depression and Anxiety in People Living With HIV | Objective The purpose of this study was to examine whether attachment insecurity, stigma, and certain demographic and medical factors predict depression and anxiety in people living with HIV (PLWH). Methods Participants were 147 PLWH who visited the outpatient infection clinic in Kyungpook National University Hospital (KNUH; Daegu, South Korea) between June 2020 and January 2021. We measured HIV-related stigma, attachment anxiety and avoidance, depressive symptoms, and anxiety symptoms. Results Logistic regression analysis showed that unemployment, longer time receiving antiretroviral therapy, higher attachment avoidance, and higher attachment anxiety were significant predictors of depression. Results also showed that longer time receiving antiretroviral therapy, higher attachment anxiety, and concern with public attitudes were significant predictors of anxiety. Conclusion In addition to education to reduce public stigma, interventions to reduce PLWH's self-stigma should continue. We suggest attachment-based psychotherapy as an effective intervention to improve PLWH's mental health. | Kim, Kyungmin; Jang, Seoyoung; Rim, Hyo-Deog; Kim, Shin -Woo; Chang, Hyun-ha; Woo, Jungmin | Kyungpook Natl Univ, Sch Med, Dept Psychiat, 130 Dongdeok Ro, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Dept Internal Med, Daegu, South Korea | Kim, Sun/G-3451-2013 | 57201480192; 57258167000; 15768078500; 8710731500; 7407521688; 56241307600 | woojm3@hanmail.net; | PSYCHIATRY INVESTIGATION | PSYCHIAT INVEST | 1976-3026 | 20 | 5 | SCIE;SSCI | PSYCHIATRY | 2023 | 1.8 | 60.8 | 0 | 2025-06-25 | 1 | 1 | Keywords HIV; Object attachment; Social stigma; Depression; Anxiety | QUALITY-OF-LIFE; ADULT ATTACHMENT; PATIENT ATTACHMENT; SOCIAL SUPPORT; KOREAN VERSION; DISORDER; STYLE; EXPECTANCY; ACTIVATION; MECHANISMS | Anxiety; Depression; HIV; Object attachment; Social stigma | adult; aged; antiretroviral therapy; anxiety; Article; attachment insecurity; attitude; avoidance behavior; CD4 lymphocyte count; depression; educational status; emotion; emotion assessment; emotional attachment; experiences in close relationships scale; female; Generalized Anxiety Disorder-7; HIV stigma scale; human; Human immunodeficiency virus infected patient; male; mental disease assessment; middle aged; patient compliance; Patient Health Questionnaire 9; prediction; social stigma; treatment duration; unemployment; virus transmission; young adult | English | 2023 | 2023-05 | 10.30773/pi.2022.0271 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Exploration of changes in the chemical composition of sedimentary organic matter and the underlying processes during biodegradation through advanced analytical techniques | Rationale. Although the scientific community has widely investigated organic matter biodegradation processes, only a limited number of studies have explored the molecular changes of this material, whereas its structure, composition and origin play a key role in these processes. Methodology. We decided to examine the effects of biodegradation on the chemical composition of sedimentary organic matter and to explore the underlying mechanisms. We conceived a laboratory-based degradation experiment utilising organic-rich sediments artificially composed of two contrasting organic matter end-members (i.e. soil and algae) under two oxygen conditions. The sediment samples before and after incubation were then analysed by laser desorption ionisation-Fourier-transform-ion cyclotron resonance-mass spectrometry for molecular characterisation and by thermally assisted hydrolysis and methylation gas chromatography-mass spectrometry in order to offer insights into the mechanisms driving the biodegradation processes. Results. Our results from molecular characterisation unveiled distinct pathways of biodegradation contingent upon the source material. Moreover, they hinted at a predilection for altering high molecular weight compounds like lignin & carboxylic-rich alicyclic molecules (CRAM) and condensed aromatic structures (CAS), manifesting as a conversion into lower molecular weight counterparts. Furthermore, the complementary findings from biomarker analyses underscored the influence of environmental factors - specifically oxygen conditions and microbial communities - on organic matter decomposition. Discussion. Although this study is a controlled laboratory experiment and more studies are needed, it demonstrates the intricate interplay among chemical, biological and environmental factors that profoundly shape the reactivity of organic matter. This study underscores the critical need for persistent inquiry, aimed at unravelling the factors and conditions governing the diverse pathways of biodegradation. | Derrien, Morgane; Jeanneau, Laurent; Jarde, Emilie; Hur, Jin; Kim, Sunghwan | Sejong Univ, Dept Environm & Energy, Seoul 05006, South Korea; Univ OHiggins, Inst Ciencias Agroalimentarias Anim & Ambientales, San Fernando, Chile; Univ Rennes 1, Ctr Natl Rech Sci CNRS, Geosci Rennes UMR 6118, F-35042 Rennes, France; Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Mass Spectrometry Based Convergence Res Ctr, Daegu 41566, South Korea | Derrien, Morgane/AAV-7191-2020; Kim, Sunghwan/HKN-9812-2023 | 37030902300; 56028580500; 6507390113; 7005096817; 57203772967 | morgane.derrien@uoh.cl; | ENVIRONMENTAL CHEMISTRY | ENVIRON CHEM | 1448-2517 | 1449-8979 | 20 | 5 | SCIE | CHEMISTRY, ANALYTICAL;ENVIRONMENTAL SCIENCES | 2023 | 2 | 60.8 | 0.28 | 2025-06-25 | 2 | 2 | aquatic source; biodegradation; biomarkers; LDI-FT-ICR-MS; microbial communities; molecular characterisation; sedimentary organic matter; terrestrial source | THERMALLY ASSISTED HYDROLYSIS; RESOLUTION MASS-SPECTROMETRY; MICROBIAL COMMUNITIES; MARINE-SEDIMENTS; SOIL; CARBON; DEGRADATION; DIAGENESIS; DOM; LAKE | aquatic source; biodegradation; biomarkers; LDI-FT-ICR-MS; microbial communities; molecular characterisation; sedimentary organic matter; terrestrial source | biodegradation; chemical composition; desorption; hydrolysis; lignin; methylation; microbial community; organic matter | English | 2023 | 2023 | 10.1071/en23083 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Heightened but Inefficient Thought-Action Fusion in Obsessive-Compulsive Disorder: New Insight From a Multiple Trial Version of the Classic Thought-Action Fusion Experiment | Objective Thought-action fusion (TAF), which is a tendency to make the relationship between one's thoughts and external conse-quences, is a dysfunctional belief linked to obsessive-compulsive disorder (OCD). While the TAF is commonly evaluated using the Thought-Action Fusion Scale (TAFS), it cannot fully reflect the actual experience of experimentally evoked TAF. In the present study, we applied a multiple-trial version of the classic TAF experiment and evaluate two variables, reaction time (RT) and emotional intensity (EI). Methods Ninety-three patients with OCD and 45 healthy controls (HCs) were recruited. The participants were asked to read the name of a close or neutral person embedded in different positive (PS) or negative (NS) TAF statements. During the experiments, RT and EI were gathered. Results The OCD patients presented with longer RT and lower EI in the NS condition than HCs. In each group, the HCs showed a significant relationship between RT in the NS condition and TAFS scores, whereas the patients did not, although they had higher TAFS scores than the HCs. In contrast, the patients showed a trend toward a correlation between RT in the NS condition and guilt. Conclusion These findings may indicate our multiple-trial version of the classical TAF showed reliable results of the two new variables, especially RT, in the task and allow to newly identify paradoxical patterns in which the TAFS scores are high but actual performance is impaired, that is, the inefficient activation of TAF in OCD.

| ○ | ○ | Article | Is Acceptance and Commitment Therapy Effective for Any Obsessive-Compulsive Symptom Dimensions? | Objective Acceptance and commitment therapy (ACT) has been recently introduced for treating obsessive-compulsive disorder (OCD). Although there are data supporting the efficacy of ACT, only few studies have investigated the effectiveness of ACT against any obsessive-compulsive (OC) symptom dimension or a specific dimension alone. Methods In total, 64 patients with OCD received an 8-session ACT group program. All measures were evaluated before and after treatment. The Dimensional Obsessive-Compulsive Scale was used to assess OCD severity across the four empirically supported symptom dimensions (i.e., contamination, responsibility for harm, unacceptable thoughts, and symmetry). ACT processes were evaluated using the Acceptance and Action Questionnaire-II (AAQ-II), Acceptance and Action Questionnaire for Obsessions and Compulsions (AAQOC), and Cognitive Fusion Questionnaire. Results After an 8-week program, there were significant reductions in all four OC symptom dimensions after ACT. The unacceptable thoughts and contamination domains had medium effect size. The responsibility for harm and symmetry dimensions had small effect size. The unacceptable thoughts dimension was significantly correlated with all ACT process measures. The symmetry dimension was significantly correlated with AAQ-OC and AAQ-II scores while the responsibility for harm dimension was correlated with AAQ-II alone. However, the contamination dimension was not associated with any process measures. Conclusion ACT may be effective for managing all four symptom dimensions with small to moderate effect size. Moreover, depending on the symptom dimension, there may be different relationship patterns between symptom reduction and changes in ACT processes. | Lee, Sang Won; Choi, Mina; Lee, Seung Jae | Kyungpook Natl Univ, Sch Med, Dept Psychiat, 680 Gukchaebosang Ro, Daegu 41944, South Korea; Kyungpook Natl Univ, Dept Psychiat, Chilgok Hosp, Daegu, South Korea; Kyungpook Natl Univ, Inst Biomed Engn Res, Daegu, South Korea; Kyungpook Natl Univ Hosp, Dept Psychiat, Daegu, South Korea | ; Lee, Seung/AAI-1191-2020 | 55820414800; 58010223000; 58509400200 | jayleemd@knu.ac.kr; | PSYCHIATRY INVESTIGATION | PSYCHIAT INVEST | 1976-3026 | 20 | 10 | SCIE;SSCI | PSYCHIATRY | 2023 | 1.8 | 60.8 | 0.35 | 2025-06-25 | 1 | 2 | Effectiveness; Obsessive-compulsive; Symptom dimension; Process; Cognitive-behavioral | PSYCHOMETRIC PROPERTIES; EXPERIENTIAL AVOIDANCE; ACTION QUESTIONNAIRE; VALIDATION; VERSION; TRIAL | Cognitive-behavioral; Effectiveness; Obsessive-compulsive; Process; Symptom dimension | acceptance and action questionnaire; acceptance and action questionnaire for obsessions and compulsions; acceptance and action questionnaire II; acceptance and commitment therapy; adult; Article; Beck Depression Inventory; cognition assessment; cognitive fusion questionnaire; contamination; dimensional obsessive-compulsive scale; disease severity assessment; female; human; major clinical study; male; mental disease assessment; obsessive compulsive disorder; responsibility; responsibility for harm; Structured Clinical Interview for DSM Disorders; symptom; thinking; unacceptable thought; Yale Brown Obsessive Compulsive Scale | English | 2023 | 2023-10 | 10.30773/pi.2023.0109 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Prevalence of Mental Disorders and Associated Factors in Korean Adults: National Mental Health Survey of Korea 2021 | Objective Mental health is a global concern and needs to be studied more closely. We aimed to estimate the prevalence of mental disorders and their associated factors among the general population in Korea.Methods The National Mental Health Survey of Korea 2021 was conducted between June 19 and August 31, 2021 and included 13,530 households; 5,511 participants completed the interview (response rate: 40.7%). The lifetime and 12-month diagnosis rates of mental disorders were made using the Korean version of the Composite International Diagnostic Interview 2.1. Factors associated with alcohol use disorder (AUD), nicotine use disorder, depressive disorder, and anxiety disorder were analyzed, and mental health service utilization rates were estimated.Results The lifetime prevalence of mental disorders was 27.8%. The 12-month prevalence rates of alcohol use, nicotine use, depressive, and anxiety disorders were 2.6%, 2.7%, 1.7%, and 3.1%, respectively. The risk factors associated with 12-month diagnosis rates were as follows: AUD: sex and age; nicotine use disorder: sex; depressive disorder: marital status and job status; anxiety disorder: sex, marital status, and job status. The 12-month treatment and service utilization rates for 12-month AUD, nicotine use disorder, depressive disorder, and anxiety disorder were 2.6%, 1.1%, 28.2%, and 9.1%, respectively.Conclusion Approximately 25% of adults in the general population were diagnosed with mental disorders during their lifetime. The treatment rates were substantially low. Future studies on this topic and efforts to increase the mental health treatment rate at a national level are needed.

| ○ | ○ | Article | Validation of the Patient Health Questionnaire-9 and Patient Health Questionnaire-2 in the General Korean Population | Objective The Patient Health Questionnaire-9 (PHQ-9) and PHQ-2 have not been validated in the general Korean population. This study aimed to validate and identify the optimal cutoff scores of the PHQ-9 and PHQ-2 in screening for major depression in the general Korean population.Methods We used data from 6,022 participants of the Korean Epidemiological Catchment Area Study for Psychiatric Disorders in 2011. Major depression was diagnosed according to the Korean Composite International Diagnostic Interview. Validity, reliability, and receiver operating characteristic curve analyses were performed using the results of the PHQ-9 and Euro Quality of life-5 dimension (EQ-5d).Results Of the 6,022 participants, 150 were diagnosed with major depression (2.5%). Both PHQ-9 and PHQ-2 demonstrated relatively high reliability and their scores were highly correlated with the "anxiety/depression" score of the EQ-5d. The optimal cutoff score of the PHQ-9 was 5, with a sensitivity of 89.9%, specificity of 84.1%, positive predictive value (PPV) of 12.6%, negative predictive value (NPV) of 99.7%, positive likelihood ratio (LR+) of 5.6, and negative likelihood ratio (LR-) of 0.12. The optimal cutoff score of the PHQ-2 was 2, with a sensitivity of 85.3%, specificity of 83.2%, PPV of 11.6%, NPV of 99.5%, LR+ of 5.1, and LR-of 0.18.Conclusion The PHQ-9 and PHQ-2 are valid tools for screening major depression in the general Korean population, with suggested cutoff values of 5 and 2 points, respectively. | Kim, Minah; Jung, Sanghyup; Park, Jee Eun; Sohn, Jee Hoon; Seong, Su Jeong; Kim, Byung-Soo; Chang, Sung Man; Hong, Jin Pyo; Hahm, Bong-Jin; Yeom, Chan-Woo | Seoul Natl Univ Hosp, Dept Neuropsychiat, Seoul, South Korea; Seoul Natl Univ, Coll Med, Dept Psychiat, Seoul, South Korea; Seoul Natl Univ, Coll Med, Dept Psychiat & Behav Sci, Seoul, South Korea; Seoul Natl Univ Hosp, Publ Healthcare Ctr, Seoul, South Korea; Kangdong Sacred Heart Hosp, Dept Psychiat, Seoul, South Korea; Kyungpook Natl Univ, Sch Med, Dept Psychiat, Daegu, South Korea; Sungkyunkwan Univ, Sch Med, Samsung Med Ctr, Dept Psychiat, Seoul, South Korea; Seoul Natl Univ, Inst Human Behav Med, Med Res Ctr, Seoul, South Korea; Eulji Univ, Uijeongbu Eulji Med Ctr, Sch Med, Dept Psychiat, 712 Dongil Ro, Uijeonbu 11759, South Korea | ; Hahm, Bong-Jin/J-5714-2012; Kim, Byung-Soo/H-4047-2013 | 57191729747; 57213141859; 56119414400; 35216092100; 55079714000; 57214661242; 23092756400; 55729426400; 6601908426; 57213142305 | chwoye@eulji.ac.kr;chwoye@gmail.com; | PSYCHIATRY INVESTIGATION | PSYCHIAT INVEST | 1976-3026 | 20 | 9 | SCIE;SSCI | PSYCHIATRY | 2023 | 1.8 | 60.8 | 2.47 | 2025-06-25 | 12 | 14 | Depression; PHQ-9; PHQ-2; Screening; Cutoff; Korea | INTERNATIONAL DIAGNOSTIC INTERVIEW; MENTAL-HEALTH; PRIMARY-CARE; DEPRESSION; PHQ-9; VERSION; VALIDITY; DISORDERS; SERVICES; SUICIDE | Cutoff; Depression; Korea; PHQ-2; PHQ-9; Screening | adult; aged; anxiety; Article; catchment area; confirmatory factor analysis; controlled study; diagnostic test accuracy study; DSM-IV; female; human; interview; Korean (people); major clinical study; major depression; male; marriage; Patient Health Questionnaire 2; Patient Health Questionnaire 9; predictive value; psychiatry; psychometry; quality of life; questionnaire; receiver operating characteristic; reliability; sensitivity and specificity; test retest reliability; validity | English | 2023 | 2023-09 | 10.30773/pi.2023.0100 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Validation of the Short Form of the Mood Instability Questionnaire-Trait (MIQ-T-SF) in the Korean General Population | Objective Mood instability (MI) is a clinically significant trait associated with psychiatric disorders. However, there are no concise mea-surements to evaluate MI. The initial Mood Instability Questionnaire-Trait (MIQ-T) was developed to fill this gap. The current study aimed to create a short form of MIQ-T (MIQ-T-SF) that measures MI with high validity and reliability in the Korean general population.Methods Of the 59 items in the MIQ-T, 17 items were chosen for the MIQ-T-SF following the factor analysis process. In total, 540 par-ticipants completed the MIQ-T-SF. Cronbach's alpha and McDonald's omega were used to evaluate reliability. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to determine construct validity. Concurrent validity was confirmed via com-parisons with Personality Assessment Inventory-Borderline Features Scale. Measurement invariance across gender and age groups was confirmed before analyzing differences in scores using Kruskal-Wallis test.Results The MIQ-T-SF displayed expected correlations and high internal consistency (& alpha;=0.71-0.90, & OHM;t=0.72-0.92). Using EFA and CFA, a five-factor structure was confirmed. Measurement invariance was supported, and gender differences were observed.Conclusion The MIQ-T-SF is an accurate and reliable method to detect MI in the Korean general population. The study's results offer new perspectives for future studies on MI. | Yoon, Joohyun; Yu, Hyeona; Jang, Yoonjeong; Lee, Daseul; Park, Yun Seong; Ihm, Hong Kyu; Ryoo, Hyun A.; Cho, Nayoung; Lee, Jakyung; Kim, Yeoju; Park, Jungkyu; Kang, Hyo Shin; Ha, Tae Hyon; Myung, Woojae | Seoul Natl Univ, Dept Neuropsychiat, Bundang Hosp, Seongnam, South Korea; Kyungpook Natl Univ, Dept Psychol, Daegu, South Korea; Seoul Natl Univ, Dept Psychiat, Coll Med, Seoul, South Korea; Seoul Natl Univ, Dept Neuropsychiat, Bundang Hosp, 29 Gumi ro 173 beon gil, Seongnam 13619, South Korea | ; Kim, Youl-Ri/AAE-5170-2021; Jang, Yoonjeong/LKN-3419-2024; Myung, Woojae/AAD-3016-2021; Park, Christopher/L-6074-2017; Ha, Tae/U-5558-2019 | 57226706803; 57910913300; 57223872445; 57973764300; 57212764489; 57867250000; 57230578700; 57230969400; 57972918600; 57973341800; 56206565000; 57219595147; 7203014550; 37099034100 | hatti@snu.ac.kr;wmyung@snu.ac.kr; | PSYCHIATRY INVESTIGATION | PSYCHIAT INVEST | 1976-3026 | 20 | 5 | SCIE;SSCI | PSYCHIATRY | 2023 | 1.8 | 60.8 | 0 | 2025-06-25 | 0 | 0 | Emotional distress; Questionnaire design; Validation study; Factor analysis | OF-FIT INDEXES; TEMPS-A; SEASONAL-CHANGES; BEHAVIOR; EMOTION; BIPOLAR; GENDER | Emotional distress; Factor analysis; Questionnaire design; Validation study | Article; cognitive behavioral therapy; concurrent validity; confirmatory factor analysis; construct validity; Cronbach alpha coefficient; Diagnostic and Statistical Manual of Mental Disorders; emotional stress; emotionality; ethnobotany; exploratory factor analysis; groups by age; human; internal consistency; Korean (people); Kruskal Wallis test; mental instability; mood instability questionnaire trait; personality assessment; personality disorder; questionnaire; reliability; sex difference; Temperament Evaluation of Memphis, Pisa, Paris and San Diego; validation study | English | 2023 | 2023-05 | 10.30773/pi.2022.0275 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Article | Risk factors for mortality in intensive care unit patients with Stenotrophomonas maltophilia pneumonia in South Korea | Background: Stenotrophomonas maltophilia has been increasingly recognized as an opportunistic pathogen associated with high morbidity and mortality. Data on the prognostic factors associated with S. maltophilia pneumonia in patients admitted to intensive care unit (ICU) are lacking. Methods: We conducted a retrospective analysis of data from 117 patients with S. maltophilia pneumonia admitted to the ICUs of two tertiary referral hospitals in South Korea between January 2011 and December 2022. To assess risk factors associated with in-hospital mortality, multi-variable logistic regression analyses were performed. Results: The median age of the study population was 71 years. Ventilator-associated pneumonia was 76.1% of cases, and the median length of ICU stay before the first isolation of S. maltophilia was 15 days. The overall in-hospital mortality rate was 82.1%, and factors independently associated with mortality were age (odds ratio [OR], 1.05; 95% confidence interval [CI], 1.00-1.09; P=0.046), Sequential Organ Failure Assessment (SOFA) score (OR, 1.21; 95%; CI, 1.02-1.43; P=0.025), corticosteroid use (OR, 4.19; 95% CI, 1.26-13.91; P=0.019), and polymicrobial infection (OR, 95% CI 0.07-0.69). However, the impact of appropriate antibiotic therapy on mortality was insignificant. In a subgroup of patients who received appropriate antibiotic therapy (n=58), anti-biotic treatment modality-related variables, including combination or empirical therapy, also showed no significant association with survival. Conclusions: Patients with S. maltophilia pneumonia in ICU have high mortality rates. Older age, higher SOFA score, and corticosteroid use were independently associated with increased in-hospital mortality, whereas polymicrobial infection was associated with lower mortality. The effect of appropriate antibiotic therapy on prognosis was insignificant. | Lee, Yong Hoon; Lee, Jaehee; Yu, Byunghyuk; Lee, Won Kee; Choi, Sun Ha; Park, Ji Eun; Seo, Hyewon; Yoo, Seung Soo; Lee, Shin Yup; Cha, Seung-Ick; Kim, Chang Ho; Park, Jae Yong | Kyungpook Natl Univ, Sch Med, Dept Internal Med, Daegu, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Intens Care Unit, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Daegu, South Korea; Kyungpook Natl Univ, Med Res Collaborat Ctr, Biostat, Daegu, South Korea | Lee, Jaehee/S-1697-2018; Park, Jae Yong/ISS-5916-2023; Lee, Jun Young/CAI-2335-2022 | jaelee@knu.ac.kr; | ACUTE AND CRITICAL CARE | ACUTE CRIT CARE | 2586-6052 | 2586-6060 | 38 | 4 | ESCI | CRITICAL CARE MEDICINE | 2023 | 1.7 | 60.9 | 3 | anti-bacterial agents; intensive care units; pneumonia; risk factors; Stenotrophomonas maltophilia | RESPIRATORY-TRACT | English | 2023 | 2023-11 | 10.4266/acc.2023.00682 | 바로가기 | 바로가기 | 바로가기 | |||||||||
| ○ | ○ | Article | Trade diversion effects of the US-China trade war on Vietnam | This paper empirically examines the US-China trade war that began in mid-2018, focusing on the impact on a third country, Vietnam. Using regression analysis, we found that while the trade war had a negative impact on US imports from China for all targeted products, there was a partial offset from increased imports from other countries. Notably, US imports from Vietnam experienced a sharp increase, particularly after the third round of US import tariffs on Chinese goods. Additionally, our research reveals that the four rounds of tariff escalation affected US imports from China differently depending on their end-use and technology intensity. | Choi, Bo-Young; Nguyen, Thuy Linh | Kyungpook Natl Univ, Sch Econ & Trade, Daegu, South Korea; Kyungpook Natl Univ, Dept Int Trade, Daegu, South Korea; Kyungpook Natl Univ, Sch Econ &Trade, 80 Daehak Ro, Daegu 41566, South Korea | 57226503191; 58553209700 | bychoi2@knu.ac.kr; | PACIFIC ECONOMIC REVIEW | PAC ECON REV | 1361-374X | 1468-0106 | 28 | 4 | SSCI | ECONOMICS | 2023 | 1.1 | 60.9 | 1.02 | 2025-06-25 | 6 | 8 | CREATION; AGREEMENTS | China; United States; Viet Nam; empirical analysis; international trade; regression analysis; tariff structure; war | English | 2023 | 2023-10 | 10.1111/1468-0106.12435 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | Article | An Intensive Study on Algal Diversity in the Ancient Man-Made Aquatic Ecosystem of Tiruvallur, South India: Exploration for Sustainable Development | Eco-friendly and beneficial nature algae make it prominent in our earth as well as for human life. In recent decades, microalgal applications is sought in varied fields from the remediation of wastes to the production of pharmaceutical products. Still, more extensive research on bioprospecting should to conducted to get the genus-specific or species-specific applications of microalgae with high efficiency. This inquiry was carried out (October 2021 to September 2022) for the effectual understanding of microalgal composition structure along with seasonal physicochemical variations in the age-old holy tank at Tiruvallur, southeast India. This inquiry also acts as the source data and makes the bioprospecting process easier. It also ignites the researchers to address the microalgae seasonal composition structure of peculiar wet environments. A total of 41 microalgae species were recorded, in which six major algal groups were in order of, Chlorophyceae > Bacillariophyceae > Cyanophyceae > Euglenophyceae > Zygnematophyceae > Trebouxiophyceae. Mean seasonal abundance was highest in the summer season (351 cells/L) and lowest in the monsoon (113 cells/L). One-way ANOVA showed seasonal variations of physicochemical parameters, in which the majority of them attained their peak during summer. Mean values of water temperature, pH, salinity, total dissolved solids, total solids, electrical conductivity, chemical oxygen demand, total hardness, total alkalinity, ammonia, nitrite-nitrogen, and nitrate-nitrogen for the summer were 31.43 °C, 8.53, 0.56 ppt, 383 mg/L, 525 mg/L, 0.85 mS/cm, 46.27 mg/L, 300 ppm, 251.67 ppm, 1.51 mg/L, 0.62 mg/L, and 0.70 mg/L, respectively. Karl Pearson's correlation revealed a most significant relationship between water quality factors and algal density. The Shannon’s diversity index (2.78–3.39) indicated moderately rich microalgal diversity in the study area. Palmer's pollution index stated that the temple tank was organically polluted all over the study period except November.

| ○ | Article | Deciphering Microalgal Diversity of Peculiar Lentic Ecosystem in Chennai, South India: A Way Towards Sustainability | Microalgae are quickly gaining attention among the researchers in various aspects such as biofuel applications, biogas, biomass production, waste water treatment, carbon fixation, animal feed ingredients, pigment production, and pharmaceutical products. One of the approaches to choose microalgae for biotechnological applications is to investigate their diversity and abundance in all possible wet environments. Samples were collected from three sampling sites for the period of 1 year (October 2021–September 2022) in Vadapalani temple tank at Chennai. Physicochemical parameters in current investigation were estimated according to APHA, 2017. Qualitative and quantitative analyses of phytoplankton were done throughout the study period. One-way ANOVA (Analyses of Variance) and Karl Pearson’s correlation coefficient were estimated using SPSS (V.26.0). A total of 11 diversity indices were estimated using PAST (V 4.0). A total of 52 algal species were identified, prevailed over by Chlorophyceae (15 species), followed by Zygnematophyceae, Bacillariophyceae, Cyanophyceae, and Trebouxiophyceae. Chlorophyceae quantitatively structured the major category. The maximum and minimum values of density were observed during the season of summer (287 Cells/L) and monsoon (80 Cells/L), respectively. Chlorophyceae showed dominance with a density of 168 cells/L. The maximum and minimum densities of Chlorophyceae were recorded in the summer season (55 cells/L) and monsoon season (24 cells/L), respectively. Shannon’s index (H’) attained its zenith in February and April month of 2022 (3.60). This study further ignites the researchers to phycoprospect various temple water to address the nature of microalgae occurrence and for biotechnological purposes. © 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature. | Subramanian, Keerthivarman G.; Dhanushkodi, Manikandavelu; Satyapriyan, Aruna; Nagarajan, Muralidharan; Muthusamy, Govarthanan | Department of Aquatic Environment Management, Tamil Nadu Dr. J.

| ○ | ○ | Article | Cochlear Implantation in the Elderly: Speech Performance, Associated Factor, Complication, and Surgical Safety | Background and objectives: The guidelines for cochlear implantation (CIs) are expanding, and the number of CI procedures performed on the elderly is increasing. The purpose of this study was to analyze the results and safety of cochlear implantation in the elderly, as well as to evaluate the predictive factors on CI outcomes.Subjects and methods: The study included 56 patients aged >= 40 years, who received CIs between 2009 and 2020. They were divided into two groups: 27 younger adults (40-64 years) and 29 elderly (>64 years). The study compared their pre- and postoperative speech perception and category of auditory performance (CAP) scores, surgical complications, and hospitalization periods. It also evaluated associated factors in the elderly group by examining categorical and continuous variables and postoperative CAP score.Results: There was a significant improvement in speech recognition tests (both word and sentence) and CAP scores in both groups compared to the pre-implantation scores (p<0.001). Postoperative results were slightly lower in the elderly group than in younger adults for sentence recognition and CAP scores, except for word recognition. No significant associated factors were found on postoperative CAP scores, except for etiology. Postoperative CAP significantly improved in the sudden hearing loss group compared to the groups with other etiologies (p=0.045). The elderly group had more comorbidities than that in the younger adult group (p=0.026), but there were no significant differences in postoperative complications and hospitalization periods.Conclusions: While speech recognition and CAP scores were relatively lower in the elderly group compared to the younger adults, the elderly group showed significant improvements in audiological results after CI. Moreover, CI was safe and well tolerated in elderly patients. | Oh, Minji; Oh, Eun Jung; Jung, Boseung; Yoo, Myung Hoon; Yoo, Shin Young; Jung, Da Jung; Lee, Kyu-Yup | Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Otorhinolaryngol Head & Neck Surg, Daegu, South Korea; Seoul Natl Univ, Myungdong Yonsei ENT Clin, Seoul, South Korea; Kyungpook Natl Univ Hosp, Dept Otolaryngol, 130 Dongdeok, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Dept Otorhinolaryngol Head & Neck Surg, 130 Dongdeok Ro, Daegu 41944, South Korea | 오, 은정/GSO-2090-2022; Lee, Doh Young/GLR-9586-2022 | 57877906400; 57844473100; 58740925700; 22956750000; 55857092600; 57220970862; 22135779500 | wjddk0731@naver.com;kylee@knu.ac.kr; | JOURNAL OF AUDIOLOGY AND OTOLOGY | J AUDIOL OTOL | 2384-1621 | 2384-1710 | 27 | 4 | ESCI | OTORHINOLARYNGOLOGY | 2023 | 1.1 | 61.4 | 0 | 2025-06-25 | 0 | 0 | Cochlear implantation; Aged; Speech perception; Postoperative complication | HEARING IMPAIRMENT; ADULTS; OUTCOMES | Aged; Cochlear implantation; Postoperative complication; Speech perception | English | 2023 | 2023-10 | 10.7874/jao.2023.00136 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Fabrication and properties of the 6-aminocaproic acid-modified MXene-based PA6 nanocomposites | MXene is a new type of transition metal carbon/nitride two-dimensional nanolayered material, which has attracted extensive attention in many fields due to its unique physicochemical properties. Combining MXene with high-performance polymers is expected to obtain nanocomposites with excellent comprehensive properties. In this study, MXene was first modified with acidified 6-aminocaproic acid and then mixed with Polyamide 6 (PA6) matrix. The structure, thermal stability, mechanical properties, and electromagnetic interference shielding efficiency of MXene-based PA6 nanocomposites were studied. The modified MXene was well dispersed in the PA6 matrix with beneficial interfacial adhesion, and the mechanical properties and electromagnetic interference shielding efficiency were significantly enhanced. The method used in this study provides a novel route for fabricating MXene-based polymer nanocomposites with excellent performance. | Zhang, He-Xin; Ryu, Hyun-Min; Yoon, Keun-Byoung | Anhui Univ Technol, Sch Chem & Chem Engn, Maanshan, Peoples R China; Kyungpook Natl Univ, Dept Polymer Sci & Engn, Daegu, South Korea; Kyungpook Natl Univ, Dept Polymer Sci & Engn, Daegu 41566, South Korea | Hexin, Zhang/ACI-3911-2022 | 25633288200; 57254125300; 7401607550 | kbyoon@knu.ac.kr; | COMPOSITE INTERFACES | COMPOS INTERFACE | 0927-6440 | 1568-5543 | 30 | 5 | SCIE | MATERIALS SCIENCE, COMPOSITES | 2023 | 2.1 | 61.4 | 0 | 2025-06-25 | 0 | 0 | Mxene; polyamide 6; nanocomposite; electromagnetic interference shielding | TRANSITION-METAL CARBIDES; MICRO-SUPERCAPACITORS; PERFORMANCE; STABILITY; OXIDATION; FILMS | electromagnetic interference shielding; Mxene; nanocomposite; polyamide 6 | Efficiency; Electromagnetic pulse; Electromagnetic shielding; Electromagnetic wave interference; Fabrication; Physicochemical properties; Signal interference; Transition metals; 6-aminocaproic acid; Electromagnetic interference shielding; matrix; Mxene; Nano-layered materials; Physicochemical property; Polyamide 6; Property; Shielding efficiency; Two-dimensional; Nanocomposites | English | 2023 | 2023-05-04 | 10.1080/09276440.2023.2179240 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
