It is estimated that there is a total of approximately 100,000 species in Korea. However, the number is currently about 30,000 and only 16,027 species are listed in the 'Species Korea' (as of December, 2014). Of the listed species, 51 species are designated as the Endangered Species Class I while 195 species are in the Class II, totaling 246 endangered species including 20 mammals. Under the circumstances that development (e.g., roads) is increasingly threatening the persistence of endangered mammals, it is significant to identify and preserve suitable habitats for them. In this context, evaluating the values of the suitable habitat environment would serve as essential information for development decision making. This study estimated the values of endangered mammals' forest habitats through spatialization of habitat services. In doing so, a species distribution model, Maximum Entropy Model (MaxEnt) was utilized for a group of endangered mammals including, mountain goat, wildcat, marten cat, and flying squirrel. To calculate the values per unit area, a benefit transfer method was used based on the point-estimate technique with the best available values estimated previously. The range of discount rate of 3.0 to 5.5 percent was applied taking the notion of social discount rate into account. As a result, the province with the highest values for endangered mammal habitats appeared to be Gangwon, followed by Gyeongbuk and Gyeongnam. The monetary values of the endangered mammal habitats were estimated to be 330 billion to 421 billion won per year.

게임 중독 청소년의 게임이용 맥락과 의미를 이해하기 위해 실시한 심층 인터뷰 결과, 먼저 게임은 또래 집단의 네트워크를 기반으로 하는 이용 규범을 통하여 중독적 게임 이용을 유도해내는 속성이 있으며, 게임 장르의 진화와 스마트 기기의 확산도 중독적인 게임 이용을 이끌어내는 것으로 드러났다. 특히 또한 게임 속의 가상세계는 청소년들에게 현실에게 결핍되어있기 쉬운 개인적 성취감이나 정체성에 대한 욕구, 사회적 인정과 지지를 손쉽게 보상받는 대안적 공간이었다. 이들에게 게임은 현실세계에서는 결핍되어 있는 다양한 청소년기의 욕구에 대한 풍부한 심리적 보상과 경험을 가능하게 하는 가상공간으로 의미를 지니며 또래 집단의 적극적 문화실천으로 경험되고 있었다. 이러한 연구 결과는 게임 매체의 통제와 청소년의 개인적 특성에 초점을 맞춘 현재의 게임규제 접근방식에 대해 주요한 시사점을 던져준다.

본 연구는 착용성, 이동성, 주변 맥락과의 지속적인 관계 형성을 특징으로 하는 지능형 자켓을 디자인 할 때 사용성에 대한 기준을 제시해주기 위한 선행 연구로 실시되었다. 이를 위해 사용자 관점에서 중요하게 고려해야 할 요소들이 무엇인지 파악하고자 하였다. 먼저, 이러한 논리의 타당성을 살펴보기 위하여 전문가 평가를 실시하였다. 그 결과 지능형 자켓은 기존의 컴퓨터 인터페이스와는 차별화 되므로 사용성 평가시 그 범주를 새롭게 구성하는 것이 필요하다는 것을 확인할 수 있었다. 다음으로 사용자 그룹 인터뷰를 실시하였으며 인터뷰 참가자 집단은 도전감(challenge)이라는 준거로 신기술을 받아들이는 혁신성, 이를 받아들이는 태도에 따라 얼리 어댑터 (early adapter)와 래가드(laggard) 두 그룹으로 나눌 수 있었다. 각각의 그룹에서 중요하게 생각하는 지능형 자켓의 사용성 평가 요소는 서로 다르게 나타났다. 얼리 어댑터의 경우 컴퓨터의 연장선상에서 기능적 요소를 중요하게 생각하였고, 래가드의 경우 옷의 연장선상에서 디자인, 심리적 부담 요소를 보다 더 중요하게 생각하는 것으로 나타났다.

Objectives: There have been many studies reporting the clinical value of Euphorbia kansui Radix or Melonis Calyx, but few systematic studies of the changes that may occur after taking such herbal medication. This study aimed to investigate the characteristics of the patient group, possible changes in blood test and InBody test results, and to discover the current state and future direction of clinical use of Euphorbia kansui Radix or Melonis Calyx. Methods: This study investigated patients who were hospitalized at Kyung-Hee University Korean Medicine Hospital for at least two days from 1 March 2016 to 1 March 2019, specifically evaluating patients aged 19 and over who underwent blood tests, including an electrolyte test and an InBody test before and after taking Euphorbia kansui Radix or Melonis Calyx. Results: Among a total of 134 patients, 72 patients (53.7%) were treated with Euphorbia kansui Radix and 62 patients (46.3%) were treated with Melonis Calyx, in the context of previously diagnosed abnormal weight gain. Laboratory findings were that Na and K levels were significantly reduced in both groups. In an InBody test, body mass index (BMI), intracellular water, extracellular water, protein, mineral, and skeletal muscle were significantly reduced in both groups. Conclusions: From these results, we suggest that, although Euphorbia kansui Radix and Melonis Calyx may not induce serious adverse effects, attention should be paid to the electrolyte level with the use of these treatments. In terms of syndrome differentiation, more clinical uses will be available in the future.

With the help of a development and popularization of microarray technology that enable to us to simultaneously investigate the expression pattern of thousands of genes, the toxicogenomics experimenters can interpret the genome-scale interaction between genes exposed in toxicant or toxicant-related environment. The ultimate and primary goal of toxicogenomics identifies functional context among the group of genes that are differentially or similarly coexpressed under the specific toxic substance. On the other side, public reference databases with transcriptom, proteom, and biological pathway information are needed for the analysis of these complex omics data. However, due to the heterogeneous and independent nature of these databases, it is hard to individually analyze a large omics annotations and their pathway information. Fortunately, several web sites of the public database provide information linked to other. Nevertheless it involves not only approriate information but also unnecessary information to users. Therefore, the systematically integrated database that is suitable to a demand of experimenters is needed. For these reasons, we propose SOP (Search of Omics Pathway) database system which is constructed as the integrated biological database converting heterogeneous feature of public databases into combined feature. In addition, SOP offers user-friendly web interfaces which enable users to submit gene queries for biological interpretation of gene lists derived from omics experiments. Outputs of SOP web interface are supported as the omics annotation table and the visualized pathway maps of KEGG PATHWAY database. We believe that SOP will appear as a helpful tool to perform biological interpretation of genes or proteins traced to omics experiments, lead to new discoveries from their pathway analysis, and design new hypothesis for a next toxicogenomics experiments.

During abstinence from alcohol, craving is elicited by the cues and contexts previously associated with alcohol, and contributes to relapse. To prevent the craving and relapse experienced by alcoholics, cue-exposure therapy (CET) has been used to extinguish the association between alcohol and alcohol-related cues and contexts. This study applied CET, using a virtual reality (VR) system, to eight members of an Alcoholics Anonymous group, in eight sessions. Cues and contexts most likely to elicit an urge to drink were selected through a preliminary survey in order to compose VR-CET scenarios: a glass, bottle, food, and a bar were judged to be the most tempting for people in alcohol dependence and abstinence. By these cues and contexts, a Japanese style pub and a western bar were composed. Each session was administered for 30 minutes by a psychiatrist and included an introduction, immersion, VR navigation, interviews about feelings, and self-report questionnaires about cravings. The eight sessions consisted of initial and closing sessions, and six cue- and context-focused sessions. As a result, a reduction in cue-elicited craving after VR-CET was reported. A mean score of 15.75 (SD = 10.91) on the Alcohol Urge Questionnaire in the first session decreased to 11.57 (SD = 6.88) in the final session.

This work takes place in the context of the development of a transport phenomena simulation based on group III nitrides. Gallium and boron nitrides (GaN and BN) are both materials with interesting physical properties; they have a direct band gap and are relatively large compared to other semiconductors. The main objective of this paper is to study the effect of boron content on the electron transport of the ternary compound $B_xGa_{(1-x)}N$ and the effect of the temperature of this alloy at x=50% boron percentage, specifically the piezoelectric, acoustic, and polar optical scatterings as a function of the energy, and the electron energy and drift velocity versus the applied electric field for different boron compositions ($B_xGa_{(1-x)}N$), at various temperatures for $B_{0.5}Ga_{0.5}N$. Monte carlo simulation, was employed and the three valleys of the conduction band (${\Gamma}$, L, X) were considered to be non-parabolic. We focus on the interactions that do not significantly affect the behavior of the electron. Nevertheless, they are introduced to obtain a quantitative description of the electronic dynamics. We find that the form of the velocity-field characteristic changes substantially when the temperature is increased, and a remarkable effect is observed from the boron content in $B_xGa_{(1-x)}N$ alloy and the applied field on the dynamics of holders within the lattice as a result of interaction mechanisms.

This research is intended to study the dietary experiences by college women to promote women's health through the proper diet. The approach method was used grounded theory. The participants were selected 3 colleges in Seoul, Inchon, and Cheongju. The selected 15 women were college students who had a history of dietary experiences or who were on the way of diet at the time of the start of this research. The data were collected from August 2001 to October 2001. Data collecting method was a Focus Group Interview. The data were analysed by the Strauss and Corbin's method(1966). The results were showed that the 236 concepts in the dietary experiences were gathered into 48 sub-categories, eventually being integrated into 17 higher categories. 'Esthetic self-pursuit' is the core phenomenon of the dietary experiences. Such phenomenon is due to subjects physical problems, sense of comparison and desire of weight-loss. In the circumstantial context, the esthetic self-pursuit phenomenon is enhanced by social opinions, aesthetic senses, and the recognition of self-control. The interaction strategy of the esthetic self-pursuit can be intensified and sustained by will power, supporting systems, and accessibility. Through the dietary experiences, the body changes positive or negative figures. Following the sense of success or failure, the diet are sustained or abandoned accordingly. Therefore for the application of promoting health, an intervention strategy should be created a collect organized diet program in a social level not a private level.

Objective: Isoquinoline Alkaloids, derived from one plant (Macleaya cordata) can be an alternative when it is desired to increase performance in feedlot cattle. However, results on these nutritional additives in high energy diets in ruminants are still incipient in literature. In this context, the objective of this study was to evaluate performance and carcass traits of feedlot bulls supplemented with sanguinarine, the main alkaloid presents in Macleaya cordata in high energy density diets. Methods: Thirty-two crossbred Angus-Nelore bulls with mean initial body weight of $365{\pm}10kg$ and mean initial age of $11{\pm}3$ months were used. The experiment lasted 119 days, with 14 days of adaptation and 105 experimental days. Experimental diet consisted of 85% whole corn grains and 15% protein-vitamin-mineral nucleus and supplied ad libitum. Treatments consisted of a control diet (CON) and a diet with sanguinarine supplementation (SAN) at a dosage of 4 g of product sufficient to provide 6 mg of sanguinarine/d. Experimental design was completely randomized. Results: Dry matter intake, average daily gain and feed conversion were similar (p>0.05) between treatments. However, SAN group animals had higher carcass yield (p = 0.045) and were more efficient in the transformation of dry matter consumed in carcass gain (p = 0.046) than CON. In addition, haptoglobin, increased throughout feedlot duration meaning high challenge for the animals due to the diet, but this behavior was similar (p>0.05) between treatments. Conclusion: Sanguinarine produced positive results in relation to carcass yield and could be used as an additive for bulls fed diets receiving high energy density diet.
