| ○ | Article | Influences of patient activation on diabetes self-care activities and diabetes-specific distress | Purpose: The purpose of the study was to evaluate the influence of patient activation on diabetes self-care activities and diabetes-specific distress among patients with type 2 diabetes mellitus. Methods: This cross-sectional correlational study was a secondary data analysis, utilizing data collected from September 2016 to July 2017, for 151 adults diagnosed with type 2 diabetes in ambulatory endocrinology units of two tertiary hospitals in a metropolitan city. The instruments used for data collection included the Summary of Diabetes Self-Care Activities Questionnaire, the Patient Activation Scale, and the Brief Diabetes Distress Screening Instrument. Hierarchical multiple linear regression analyses were conducted to test the influence of patient activation levels on self-care activities and diabetes-specific distress, after controlling for demographic and clinical variables. Results: The average patient activation level was 67.8±16.72 (with the possible range from 0 to 100), and the average diabetes-specific distress level was 6.91±2.69 (with the possible range from 2 to 12). Diabetes self-care activities scores were highest in medication adherence and lowest in glucose self-monitoring. Patient activation was the significant factor influencing self-care activities, after controlling for demographic and clinical variables, but showed no significant influence on diabetes-specific distress. Oral hypoglycemic agents and insulin medications were the significant factors influencing diabetes-specific distress. Conclusion: These findings indicate the importance of nursing interventions to improve patient activation and to alleviate diabetes-specific distress. Therefore, in order to improve diabetes self-care activities, it is necessary to facilitate patient activation for diabetes care. © 2020 Korean Society of Adult Nursing. | Choi, Sookyung; Kim, Su Hyun | Ulsan University Hospital, Ulsan, South Korea; College of Nursing, Research Institute of Nursing Science, Kyungpook National University, Daegu, South Korea | 57215602352; 56664542600 | suhyun_kim@knu.ac.kr; | Korean Journal of Adult Nursing | 1225-4886 | 32 | 1 | 0.88 | 2025-06-25 | 8 | Diabetes mellitus; Patient participation; Psychological; Self care; Stress | English | Final | 2020 | 10.7475/kjan.2020.32.1.10 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Article | Inhibition effect against elastase, collagenase, hyaluronidase and anti-oxidant activity of thinning green ball apple | In this study, the anti-oxidative, health functional, and beauty food activities of water and ethanol extracts from newly bred Ruby S apple (Malus pumila Mill.). The results of measuring the 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity by treating the phenolic compound with thinning green ball apple at a concentration of 50-200 µg/mL showed that the water and ethanol extracts at a concentration of 200 µg/mL showed 94.69 and 92.24%, respectively. 2,2'-Azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging activities showed 100.30 and 99.16%, respectively, in 200 µg/mL of water and ethanol extracts. The water and ethanol extracts of Green ball showed antioxidant protection factor of 1.76 PF 1.76, respectively. The water and ethanol extracts showed 101.46 and 99.64% anti-oxidative effect on thiobarbituric acid reactive substances at phenolic concentration of 200 µg/mL. The water and ethanol extracts showed 33.28 and 32.14% hyaluronidase inhibition, respectively, at phenolic concentration of 150 µg/mL. The water and ethanol extracts showed 47.33 and 40.92% elastase inhibition and 46.19 and 65.58% collagenase inhibition at phenolic concentration of 200 µg/mL, respectively. About these experiments, thinning Green ball apple was found to exhibit anti-oxidation activity as well as hyaluronidase, elastase and collagenase inhibitory activities. Therefore, thinning Green ball apple can be considered a potential sources for new functional materials. © The Korean Society for Applied Biological Chemistry 2020. | Go, Yu-Jin; Kim, Ye-Eun; Kim, Hyun-Nam; Lee, Eun-Ho; Cho, Eun-Bi; Sultanov, Akhmadjon; Kwon, Soon-Il; Cho, Young-Je | School of Food science & Biotechnology, Kyungpook National University, 80 University Street, Bukgu, Daegu, 41566, South Korea; School of Food science & Biotechnology, Kyungpook National University, 80 University Street, Bukgu, Daegu, 41566, South Korea; School of Food science & Biotechnology, Kyungpook National University, 80 University Street, Bukgu, Daegu, 41566, South Korea; School of Food science & Biotechnology, Kyungpook National University, 80 University Street, Bukgu, Daegu, 41566, South Korea; School of Food science & Biotechnology, Kyungpook National University, 80 University Street, Bukgu, Daegu, 41566, South Korea; School of Food science & Biotechnology, Kyungpook National University, 80 University Street, Bukgu, Daegu, 41566, South Korea; Apple Research Institute, NIHHS, RDA, Gunwi, 39000, South Korea; School of Food science & Biotechnology, Kyungpook National University, 80 University Street, Bukgu, Daegu, 41566, South Korea | 57216320828; 57221955576; 57216320713; 56347429100; 57204068582; 57216320960; 59055488500; 55265396300 | yjcho@knu.ac.kr; | Journal of Applied Biological Chemistry | 1976-0442 | 63 | 1 | 0.28 | 2025-06-25 | 8 | Anti-oxidant; Collagenase; Elastase; Hyaluronidase; Thinning green ball apple | Korean | Final | 2020 | 10.3839/jabc.2020.006 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | ○ | Article | Inhibitory Potential of Bilobetin Against CYP2J2 Activities in Human Liver Microsomes | Cytochrome P450 2J2 (CYP2J2) is a member of the cytochrome P450 superfamily, and is known to be arachidonic acid epoxygenase that mediates the formation of four bioactive regioisomers of epoxyeicosatrienoic acids (EETs). CYP2J2 is also involved in the metabolism of drugs such as albendazole, astemizole, danazol, ebastine, and terfenadine. CYP2J2 is highly expressed in the heart and cancer tissues. In this study, the inhibitory potential of ten natural products against CYP2J2 activity was evaluated using human liver microsomes and tandem mass spectrometry. Among them, bilobetin, which is a kind of biflavonoid, exhibits a strong inhibitory effect against the CYP2J2-mediated astemizole O-demethylation (IC50 = 0.73 mu M) and terfenadine hydroxylation (IC50 = 0.89 mu M). This result suggests that bilobetin can be used as strong CYP2J2 inhibitor in drug metabolism study. | Wu, Zhexue; Jang, Su-Nyeong; Park, So-Young; Nguyen Minh Phuc; Liu, Kwang-Hyeon | Kyungpook Natl Univ, Mass Spectrometry Convergence Res Inst, Daegu 41566, South Korea; Kyungpook Natl Univ, Coll Pharm, BK21 FOUR Community Based Intelligent Novel Drug, Daegu 41566, South Korea; Kyungpook Natl Univ, Res Inst Pharmaceut Sci, Daegu 41566, South Korea; Vietnam Hightech Med & Pharmaceut JSC, Grp 11 Quang Minh Town, Hanoi 100000, Vietnam | 55523767300; 57211630666; 57211630074; 56522749600; 55768214700 | dstlkh@knu.ac.kr; | MASS SPECTROMETRY LETTERS | MASS SPECTROM LETT | 2233-4203 | 2093-8950 | 11 | 4 | ESCI | SPECTROSCOPY | 2020 | N/A | 0 | 2025-06-25 | 1 | 0 | bilobetin; CYP2J2; human liver microsomes; liquid chromatography-tandem mass spectrometry; natural products | CYTOCHROME-P450 2J2; ENZYMES; IDENTIFICATION; METABOLISM; PROMOTES; CLONING | Bilobetin; CYP2J2; Human liver microsomes; Liquid chromatography-tandem mass spectrometry; Natural products | English | 2020 | 2020-12 | 10.5478/msl.2020.11.4.113 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | Article | Insect repellency and crop productivity of essential oil films | The purpose of this study was to determine the effects of coniferous essential oils (EOs) blended films on insect repellence and crop productivity. Low-density polyethylene (LDPE) film is widely used, especially in agriculture and for food packaging. Ethylene vinyl acetate was blended with LDPE to reduce volatilization of EOs. An EO from Japanese cypress (Chamaecyparis obtusa) was incorporated into the blend film to conduct field research on antimicrobial and insect repellent properties. Among the various concentrations of EO, the highest concentration (2.5%) showed the highest efficiency in terms of pesticidal activity. The ability to inhibit microbial growth can be explained by the lipophilic properties of the EO component, and many studies have already demonstrated this. Agricultural films containing all types of EO have been tested on various crops such as chili, cucumber, Korean melon and have been able to verify their effectiveness in avoiding pests and increasing yields. From these results, it was found that it is reasonable to use a modified film such as a composite film containing an EO for agriculture. Thus, the modified film containing EO has undoubtedly shown impressive potential for reducing the use of pesticides in a variety of ways, not only for agricultural mulching film but also for food and agricultural product packaging. This product is an environmentally friendly chemical and is safe for agricultural and industrial and food packaging applications, among others. In particular, the use of agricultural films significantly reduces the use of pesticides, suggesting that farmers can increase their incomes by reducing working hours and costs, and increasing production. © 2020, Korean Society of Wood Science Technology.

| ○ | ○ | Review | Intangible assets and organizational citizenship behavior: A conceptual model | Through reviewing extant literature, this conceptual paper is aimed to improve the understanding of the intervening mechanisms that influence the relationship between intangible assets (IAs) and organizational citizenship behavior (OCB) to improve the performance of contemporary knowledge-dependent organizations. The authors believe this to be the first attempt to bring four major components of IAs together and look at their relationship with OCB. This helps to create awareness of the necessity of matching key resources with appropriate behavior to improve organizations' competitive advantages. The proposed model and propositions showed relationships between IAs and OCB mediated and moderated by work engagement and perceived organizational support, respectively. Moreover, this paper suggests the need for integrated multi-level studies to strengthen the links between critical resources and behaviors to put the learning organization on the right growth track. Future research is suggested on new conceptualizations of IAs, such as spiritual capital, as well as the relationship of IAs with other typologies of OCB. | Tefera, Chalachew Almaw; Hunsaker, William D. | Jimma Univ, Coll Business & Econ, Dept Management, Jimma 00387, Ethiopia; Kyungpook Natl Univ, Sch Business Adm, 80 Daehak Ro, Daegu, South Korea | ; Hunsaker, William/E-9696-2017 | 57218192527; 55974245100 | hunsaker@knu.ac.kr; | HELIYON | HELIYON | 2405-8440 | 6 | 7 | ESCI | MULTIDISCIPLINARY SCIENCES | 2020 | N/A | 0.38 | 2025-06-25 | 25 | 29 | Intangible assets; Intellectual capital; Psychological capital; Organizational citizenship behavior; Work engagement; Perceived organizational support; Entrepreneurial psychology; Human resource management; Business management; Strategic management; Research and development; Business | SOCIAL-EXCHANGE THEORY; EXTRA-ROLE BEHAVIORS; WORK ENGAGEMENT; PSYCHOLOGICAL CONTRACT; IMPRESSION MANAGEMENT; KNOWLEDGE MANAGEMENT; POSITIVE PSYCHOLOGY; JOB-SATISFACTION; IN-ROLE; PERFORMANCE | Business; Business management; Entrepreneurial psychology; Human resource management; Intangible assets; Intellectual capital; Organizational citizenship behavior; Perceived organizational support; Psychological capital; Research and development; Strategic management; Work engagement | English | 2020 | 2020-07 | 10.1016/j.heliyon.2020.e04497 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Proceedings Paper | Intelligent Target Coverage in Wireless Sensor Networks with Adaptive Sensors | Day by day innovation in wireless communications and micro-technology has evolved in the development of wireless sensor networks. This technology has applications such as healthcare supervision, home security, battlefield surveillance and many more. However, due to the use of small batteries with low power this technology faces the issue of power and target monitoring. There is much research done to overcome these issues with the development of different architecture and algorithms. In this paper, a scheduling machine learning algorithm called adaptive learning automata algorithm(ALAA) is used. It provides an efficient scheduling technique. Such that each sensor node in the network has been equipped with learning automata, and with this, they can select their proper state at any given time. The state of the sensor is either active or sleep. For the experiment, different parameters are used to check the consistency of the algorithm to schedule the sensor node such that it can cover all the targets with the use of less power. The results obtained from the experiments show that the proposed algorithm is an efficient way to schedule the sensor nodes to monitor all the targets with use of less power. On the whole, this paper manages to achieve its goal by contributing to the related research on wireless sensor networks with a new design of a learning automata scheduling algorithm. The ability of this proposed algorithm to use the minimum number of sensors to be in active state verified to reduce the use of power in the network. Thus, achieving the goal by enhancing the lifetime of wireless sensor networks. | Akram, Junaid; Malik, Saad; Ansari, Shuja; Rizvi, Haider; Kim, Dongkyun; Hasnain, Raza | Univ Sydney, Sch Comp Sci, Sydney, NSW, Australia; Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu, South Korea; Univ Glasgow, James Watt Sch Engn, Glasgow, Lanark, Scotland; Bahria Coll, Dept Comp Sci, Islamabad, Pakistan; Iwex Technicity, Rawalpindi, Pakistan | Akram, Junaid/AGT-8852-2022; Ansari, Shuja/AAH-5804-2019; Saad, Malik/ABF-9433-2021 | 57204390449; 59160400500; 57192543629; 58827383000; 35753648800; 57222096010 | jakr7229@sydney.edu.au;maliksaad@knu.ac.kr;shuja.ansari@glasgow.ac.uk;haiderrizvi@bmci.edu.pk;dongkyun@knu.ac.kr;raza@iwextech.com; | 2020 IEEE 92ND VEHICULAR TECHNOLOGY CONFERENCE (VTC2020-FALL) | 1.74 | 2025-06-25 | 10 | 15 | learning automata; sensors; targets; machine learning; minimum active sensors; wireless sensor network; adaptive learning automata algorithm; coverage area | LEARNING AUTOMATA | adaptive learning automata algorithm; coverage area; learning automata; machine learning; minimum active sensors; sensors; targets; wireless sensor network | Automata theory; Machine learning; Robots; Scheduling; Sensor nodes; Adaptive learning; Adaptive sensors; Battlefield surveillance; Efficient scheduling; Learning Automata; Micro technology; Target monitoring; Wireless communications; Learning algorithms | English | 2020 | 2020 | 10.1109/vtc2020-fall49728.2020.9348848 | 바로가기 | 바로가기 | 바로가기 | ||||||||||||
| ○ | Article | Interpretation of the statistical/dynamical prediction for seasonal tropical storm frequency in the western North Pacific | Despite the improving techniques for seasonal prediction of tropical storm frequency, attention seems focused on accuracy rather than on forecast interpretation. This study aims to show how seasonal predictions from a hybrid model, i.e. statistical/dynamical model, can be interpreted with probability distributions. The tropical storm frequency in the western North Pacific is modeled with environmental predictors through multiple linear regression. For a demonstration of the probabilistic structure of the prediction result, the forty-two member ensemble predictions from the Glosea5 model for June-July-August in 2020 are used as the dynamical input. Rather than dealing with the expected frequency, this study introduces the predictive probability for a single value of the frequency. From as many probability distributions, a marginal probability distribution is obtained as the final predictive probability distribution. The probability distribution is then compared to the climatological reference by terciles. Additionally, predictive probability distributions made with the individual predictors provide helpful information on how each contributes to the final prediction. This probabilistic interpretation procedure is expected to be effectively used for improving any hybrid approach. © 2020 The Author(s).

| ○ | Book chapter | IntersectIonalIty | Although intersectionality has become a major scholarly theory and research approach, exploration of the concept within Mormonism is still in its infancy. This chapter examines the application, or lack thereof, of intersectionality to Mormonism. We first define and contextualize the concept of intersectionality. We then look at two ways in which Mormonism may be considered intersectionally: (a) Mormonism as one of many (often marginalized) identities within a larger society; and (b) Mormonism as a socio-cultural system that produces its own (often intersectional) marginalizations. With the latter approach to LDS intersectionality, we focus first on responses to Mormonism’s marginalizations, and second on the role of intersectionality in Mormon Studies. Along the way, we identify work and activism-both potential and actual-that utilize intersectional approaches or perspectives and call for greater attention to intersectional concerns among those who study Mormonism. © 2020 selection and editorial matter, Amy Hoyt and Taylor G.

| ○ | ○ | Proceedings Paper | Intra-protocol Convergence Problem in BBRv2's Bandwidth Probing | Google introduced Bottleneck Bandwidth Round-trip propagation time (BBR), which is a new concept of congestion control algorithm. BBR measures the available bottleneck bandwidth and minimum round-trip time. It then creates network path models to maximize the delivery rate and minimize latency. However, BBR creates unfairness problem with other TCP flows and excessive packet loss in a small buffer. Google, therefore, updated BBR, creating a new version, called BBRv2, to improve coexistence with other flows and reduce aggressiveness. BBRv2 significantly improved the fairness with loss-based congestion control algorithms and reduced the number of packet retransmissions in a small buffer compared to the existing BBR. However, in this study, we confirmed that multiple BBRv2 flows that enter the same link at different times do not take up bandwidth fairly. Therefore, we evaluate the fairness between identical BBRv2 flows through the Mininet emulation and analyze the reason for this problem. The test results show that when the bottleneck buffer size is smaller than 0.2 BDP, two BBRv2 flows have similar throughput and the number of packet retransmissions greatly reduces compared to BBRv1. However, with a large buffer, the flow starting first occupies more bandwidth. | Song, Yeong-Jun; Eom, Won-Ju; Kim, Jeong-Keun; Park, Chang-Hoon; Kim, Geon-Hwan; Cho, You-Zw | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu, South Korea | 57210919165; 57221382871; 57221376838; 57221384913; 57189040274; 7404469829 | syj5385@knu.ac.kr;dnjswn9612@knu.ac.kr;kjg818@knu.ac.kr;pch4495@knu.ac.kr;kgh76@ee.knu.ac.kr;yzcho@ee.knu.ac.kr; | 11TH INTERNATIONAL CONFERENCE ON ICT CONVERGENCE: DATA, NETWORK, AND AI IN THE AGE OF UNTACT (ICTC 2020) | 2162-1233 | 0.15 | 2025-06-25 | 2 | 2 | TCP congestion control; BBRv1; BBRv2; Intra-protocol; Convergence | BBRv1; BBRv2; Convergence; Intra-protocol; TCP congestion control | Bandwidth; Traffic congestion; Bottleneck bandwidth; Convergence problems; Network paths; Packet retransmissions; Propagation time; Round-trip time; Small buffers; Unfairness problem; Packet networks | English | 2020 | 2020 | 바로가기 | 바로가기 | 바로가기 | ||||||||||||||
| ○ | Article | Introducing the Thought-Listing Technique to Measure Affective Factors Influencing Attitudes toward Science | Until now, most of tests for attitudes toward science have been conducted through structured questionnaires. The test with structured questionnaire is difficult to exclude the intention of researcher. This study focuses on the need for a more detailed assessment of the sub-elements of attitudes toward science and unstructured open tests. For the purpose of this research, the attitudes toward science were divided into cognitive, behavioral, and affective factors, with a specific focus on affective factors. An unstructured, open, thought-listing test was conducted to measure affective factors influencing attitudes toward science. In the first test, 522 students participated in a thought-listing test on the open topic of "science," and the correlation between participants' test scores and science achievements were analyzed. The results revealed that among the categories inside, science area, science learning, science teacher, scientist, the score for science learning had the highest correlation with science achievement. As a result, the second thought-listing test, conducted with 102 middle school students, was limited to the topic of "science learning in the classroom." The resulting correlation between the test score and science achievement was .257 of Pearson correlation coefficient, which was a higher correlation than that of the first test. This value is similar to or slightly higher than the relationship between science achievement and attitudes toward science found in previous studies. These findings suggest that the thought-listing technique has advantages over structured questionnaires, as it is easier to conduct, excludes researcher bias, and is a valid method to measure affective factors influencing attitudestoward science. © 2020 Horizon Research Publishing.

| ○ | ○ | Article | Introduction of Inverse Analysis Model Using Geostatistical Evolution Strategy and Estimation of Hydraulic Conductivity Distribution in Synthetic Aquifer | In many geological fields, including hydrogeology, it is of great importance to determine the heterogeneity of the subsurface media. This study briefly introduces the concept and theory of the method that can estimate the hydraulic properties of the media constituting the aquifer, which was recently introduced by Park (2020). After the introduction, the method was applied to the synthetic aquifer to demonstrate the practicality, from which various implications were drawn. The introduced technique uses a global optimization technique called the covariance matrix adaptation evolution strategy (CMA-ES). Conceptually, it is a methodology to characterize the aquifer heterogeneity by assimilating the groundwater level time-series data due to the imposed hydraulic stress. As a result of applying the developed technique to estimate the hydraulic conductivity of a hypothetical aquifer, it was confirmed that a total of 40000 unknown values were estimated in an affordable computational time. In addition, the results of the estimates showed a close numerical and structural similarity to the reference hydraulic conductivity field, confirming that the quality of the estimation by the proposed method is high. In this study, the developed method was applied to a limited case, but it is expected that it can be applied to a wider variety of cases through additional development of the method. The development technique has the potential to be applied not only to the field of hydrogeology, but also to various fields of geology and geophysics. Further development of the method is currently underway. | Park, Eungyu | Kyungpook Natl Univ, Dept Geol, Daegu, South Korea | 23995577700 | egpark@knu.ac.kr; | ECONOMIC AND ENVIRONMENTAL GEOLOGY | ECON ENVIRON GEOL | 1225-7281 | 2288-7962 | 53 | 6 | ESCI | GEOLOGY | 2020 | N/A | 0 | 2025-06-25 | 0 | 0 | aquifer characterization; inverse analysis; covariance matrix adaptation; evolution strategy; model calibration | HEAD | Aquifer characterization; Covariance matrix adaptation; Evolution strategy; Inverse analysis; Model calibration | Chinese | 2020 | 2020-12 | 10.9719/eeg.2020.53.6.703 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | Article | Investigation of the trend in adolescent mental health and its related social factors: A multi-year cross-sectional study for 13 years | We aimed to investigate the mental health change and associated social correlates in adolescents in terms of depression, suicidal ideation, and suicidal attempt. In total, 978,079 students (12–18 years old, 7th–12th grade) participated in the survey for 13 years (2006–2018) by a multiple-year cross-sectional design (not a repeat measure for smaller group). Mental health outcome variables were assessed using self-report surveys with the independent variables of sex, age, economic status, school achievement, and parental educational level. Korean social indices of income inequality (Gini index, higher scores representing greater economic inequity with score range of 0–1), education (national proportion of tertiary education attainment), and actual suicides were investigated together as related social factors. The prevalence of depressive episodes, suicidal ideation, and suicidal attempt markedly dropped by 34.6%, 42.2%, and 48.3%, respectively. Moreover, the Gini index (from 0.314 in 2008 to 0.295 in 2015) and proportion of tertiary education (from 82.1% in 2006 to 69.7% in 2018) showed a decreasing tendency. These indices and adolescent mental health outcomes highly correlated with each other (Pearson’s r between Gini index and depressive episode = 0.789, suicidal ideation = 0.724, and suicidal attempt = 0.740; Pearson’s r between proportion of tertiary education and depressive episode = 0.930, suicidal ideation = 0.809, and suicidal attempt = 0.851). Adolescent mental health has improved in the last 13 years in Korea, and improvements in social inequality (decreased Gini index) and lessened burden of academic competition (decreased national proportion of tertiary education) were significantly associated with the improvement of adolescent’s mental health. However, the impact of parental educational level on children’s mental health was relatively minimal, compared with the impact of economic inequality and academic burden. Further studies are needed to reveal the underlying mechanism for the association between adolescent mental health and sociodemographic factors to save adolescents from psychological distress. © 2020 by the authors.

| ○ | Article | Investigation on the applicability of defocus blur variations to depth calculation using target sheet images captured by a DSLR camera | Depth calculation of objects in a scene from images is one of the most studied processes in the fields of image processing, computer vision, and photogrammetry. Conventionally, depth is calculated using a pair of overlapped images captured at different view points. However, there have been studies to calculate depths from a single image. Theoretically, it is known to be possible to calculate depth using the diameter of CoC (Circle of Confusion) caused by defocus under the assumption of a thin lens model. Thus, this study aims to verify the validity of the thin lens model to calculate depth from edge blur amount which corresponds to the radius of CoC. For this study, a commercially available DSLR (Digital Single Lens Reflex) camera was used to capture a set of target sheets which had different edge contrasts. In order to find out the pattern of the variations of edge blur against varying combination of FD (Focusing Distance) and OD (Object Distance), the camera was set to varying FD and target sheet images were captured at varying OD under each FD. Then, the edge blur and edge displacement were estimated from edge slope profiles using a brute-force method. The experimental results show that the pattern of the variations of edge blur observed in the target images was apart from their corresponding theoretical amounts derived under the thin lens assumption but can still be utilized to calculate depth from a single image for the cases similar to the limited conditions experimented under which the tendency between FD and OD is manifest. © 2020 Korean Society of Surveying.

| ○ | Article | Isolation of antioxidant components from Corni fructus | A 90% ethanol extract of Corni fructus was fractioned and the active components (i.e., morroniside, loganin) were isolated for functional food materialization. More specifically, the ethanol extract was fractioned according to the solvent polarity (i.e., n-hexane, ethyl acetate, and n-butanol), and the ethyl acetate fraction was found to exhibiti the highest antioxidant capacities (i.e., total phenolic content = 145.84 GAE mg/100 mL, DPPH radical scavenging activity = 7.91 mM GAE, FRAP activity = 18.86 mM TE, ABTS radical scavenging activity = 13.36 mM TE). Diaion HP 20 gel was used for separation of the ethyl acetate fraction, and 20%, 40%, 60%, and 80% ethanol fractions were also examined. The 40% ethanol fraction was found to exhibit the highest DPPH radical scavenging activity (10.22 mM GAE), ABTS radical scavenging activity (37.29 mM TE), and FRAP activity (27.32 mM TE) (p<0.05). The total phenolic compound content (580.84 GAE mg/100 mL), total flavonoid content (166.24 CE mg/100 mL), and total anthocyanin content (0.74 mg/100 mL) followed a similar trend, again being the highest for this fraction. Two components (i.e., morriniside, loganin) were identified in the ethyl acetate and 40% ethanol fractions, and their contents were determined by high-performance liquid chromatography. Furthermore, the 40% ethanol fraction contained the highest quantity of total active components (p<0.05), and the presence of morroniside (405 [M-H]- and 451 [M+COOH-H]-) and loganin (389 [M-H]- and 435 [M+COOH-H]-) were confirmed by ultra-performance liquid chromatography-mass spectrometry.
