The purpose of this study is to provide for the basic data useful to the effective production and marketing of the foundation garments befitting adult women's body shapes and preferences, and thereby, help them improve their apparel life. For this purpose, 563 Korean adult women aged between 20-59 were sampled to survey their recognition and actual wearing condition of foundation garments and positively identify the factors affecting the practices and thereupon, determine the correlations among them by age group. Data is processed by a computer (SAS) and analyzed by using frequency, percentage, ${\chi}^2$-test, ANOVA, Duncan-test. The main results of this study are as follows; 1. The most of the adult women were aware of the basic underwear terminologies and the absolute majority of them wore brassieres, while a half of them used the girdles. In contrast, only a small portion of them wore body suites or waste-nippers and the absolute minority of them had garterbelts. 2. The use of the foundations depended much on users' ages or seasons. They had begun to wear brassieres and girdles at their age of 15 on average, and bodysuites, waist-nippers or garterbelts around their age of 20 depending on their individual needs. 3. The adult women had 3-6 brassieres and 2-3 girdles on average, but only a minority of them owned one or two body suites, waist-nippers or garterbelts. They had ever used the functional foundations (11.5%) or imported foundations (35.9%), It has been found through this study that adult women's recognition and actual wearing condition of their foundation garments differ by age group, which may well suggest that foundation production need to take such age-wise practices into consideration in setting up their foundation production and marketing strategies.

International organizations and classification societies established rules and regulations to which shipbuilders and ship operators should comply during design, construction, even operation keeping from hazard to life of crews and ocean environment. Hence, rules and regulations could be guidelines for design and construction of ship sometimes. In practical wise, ship structure designers be predisposed to design lightest and easy-to-product structures which satisfy rules and regulations. Therefore, changes of rules and regulations are remarkably important issue to related industries. In 2006, IACS established and released Common Structural Rules for Bulk Carrier and Common Structural Rules for Double Hull Oil Tanker. These CSRs are consolidated and unified rules of class society's rules. But these two rules are different from each other. IACS has plan to release unified rule of two ship type called Harmonized Common Structural Rule for Bulk Carriers and Oil Tankers. This new rule will be effective from July 2015. Hence, bulk carrier and double hull oil tanker whose contract date is on and thereafter July 2015 should be complied with CSR-H. Therefore, it is highly important to be aware of consequences and cause of consequences with respect to CSR-H. The object of this research is to compare requirements of structure scantling in way of midship area for selected target ship according to CSRs and CSR-H and to analysis cause of deviation between two rules.

This study was done to provide a case model with a concept of environmental integration based on the water circulation system. Area of interest (AOI) is the Eastern Pangyo New Town area, which has several advantages in adaptation of a water circulation system. The AOI has a potential of maintaining water resources, and has a good condition to construct the water circulation system. Research done for the purpose of the establishment of the water circulation system in the Eastern Pangyo New Town shows the following. The main sources of water supply in the water circulation system in the Eastern Pangyo New Town is from two subway stations and runoff water, along with the natural water flowing from the mountains, rain water, and stream water. It was determined that more than 35,000 tons of water would be needed for the creation of water circulation system at the Eastern Pangyo. If the creation of infrastructure for the use of runoff and rain water as well as the periodic management can be provided, it can serve as the new model for a new city with water circulation system. In addition, since the Eastern Pangyo New Town water circulation system can secure enough amount of water resources, natural drainage system (NDS) in which it can be in dry condition in non-rainy days, is applied and connected to the typical waterways. Such water circulation system has many positive aspects including the wise use of water resources, and providing wild Life animals corridors and habitats. Also, the water circulation system can lead to the environmental education to the residents and visitors on environmental awareness of the water circulation system and their environment.

Metformin is a biguanide antihyperglycemic agent often used for the treatment of non-insulin dependent diabetics (NIDDM). In this study, the pharmacokinetics and pharmacodynamics of metformin were investigated in Korean healthy volunteers during a fasting state for over 10 h. In order to evaluate the amount of glucose-lowering effect of metformin, the plasma concentrations of glucose were measured for a period of 10 h followed by the administration of metformin (oral 500 mg) or placebo. In addition, the concentration of metformin in blood samples was determined by HPLC assay for the drug. All volunteers were consumed with 12 g of white sugar 10 minutes after drug intake to maintain initial plasma glucose concentration. The time courses of the plasma concentration of metformin and the glucose-lowering effect were analyzed by nonlinear regression analysis. The estimated $C_{max}$, $T_{max}$, $CL_{t}$/F (apparent clearance), V/F(apparent volume of distribution), and half-life of metformin were 1.42$\{pm}$0.07 $\mu\textrm{g}$/mL, 2.59$\{pm}$0.18h, 66.12$\{pm}$4.6 L/h, 26.63 L, and 1.54 h respectively. Since a significant counterclock-wise hysteresis was found for the metformin concentration in the plasma-effect relationship, indirect response model was used to evaluate pharmacodynamic parameters for metformin. The mean concentration at half-maximum inhibition $IC_{50}$, $k_{in}$, $k_{out}$ were 2.26 $\mu\textrm{g}$/mL, 83.26 $H^{-1}$, and 0.68 $H^{-1}$, respectively. Therefore, the pharmacokinetic-pharmacodynamic model may be useful in the description for the relationship between plasma concentration of metformin and its glucose-lowering effect.

The virus isolated from patients with severe pneumonia of unknown etiology in Wuhan City, Hubei province in China was termed SARS-CoV-2 and the World Health Organization (WHO) named the disease caused by this virus as coronavirus disease 2019 (COVID-19). The COVID-19 infection has spread rapidly and become a pandemic. In July 2020, there were 13.25 million infected patients and over 570,000 deaths worldwide, and 13,711 infected patients and 294 deaths were reported in South Korea. Since the primary mode of transmission of COVID-19 is through respiratory droplets, the importance of preventive measures, including social distancing, has become important in daily life. In response to the continuous spread of COVID-19, this study developed three guidelines for preventing COVID-19 for the food service industry including childcare centers, institutional foodservices and restaurants by the integration of the manual of controlling foodborne illness. These are included the COVID-19 prevention action methods for food deliverers, for food service administrator, for foodservice works and for customers. All guidelines were designed for easy understanding using illustrations and have been systematically explained subject wise. Thus, these COVID-19 prevention guidelines can be appropriately applied depending on the specific situation and workplace. In addition, they are worthy as educational materials that contribute to the food safety.

Diabetes is known to be one of common causes for several types of peripheral nerve damage. Diabetic neuropathy (DN) is a significant complication lowering the quality of life that can be frequently found in diabetes patients. In this study, the metabolomic characteristic of DN and Diabetes was investigated with NMR spectroscopy. The sera samples were collected from DN patients, Diabetes patients, and healthy volunteers. Based on the pair-wise comparison, three metabolites were found to be noticeable: glucose, obviously, was upregulated both in DN patients (DNP) and Diabetes. Citrate is also increased in both diseases. However, the dietary nutrient and biosynthesized metabolite from glucose, ascorbate, was elevated only in DNP, compared to healthy control. The multivariate model of OPLS-DA clearly showed the group separation between healthy control-DNP and healthy control-Diabetes. The most significant metabolites that contributed the group separation included glucose, citrate, ascorbate, and lactate. Lactate did not show the statistical significance of change in t-test while it tends to down-regulated both in DNP and Diabetes. We also conducted the ROC curve analysis to make a multivariate model for discrimination of healthy control and diseases with the identified three metabolites. As a result, the discrimination model between healthy control and DNP (or Diabetes) was successful while the model between DNP and Diabetes was not satisfactory for discrimination. In addition, multiple combinations of lactate and citrate in the OPLS-DA model of healthy control and diabetes group (DNP + Diabetes patients) gave good ROC value of 0.952, which imply these two metabolites could be used for diagnosis of Diabetes without glucose information.

This research attempted to investigate the real state of adolescent smoking and drinking, and to study how stress influences on smoking and drinking of high school students. This data was collected from 837 first and second grade students in a vocational high school in Go-yang city, Gyeonggi province. Data analysis consisted of frequency, percentage, Chi-square, T-test, step-wise regression analysis, using SPSSWIN. The results of analysis were as follows: First, 51.7% of the students have never smoked, while 48.3% have experienced smoking. Most students started smoking in the second year of the middle school, though 17.6% of the smokers already started in the elementary school. The strongest motive of initial smoking was curiosity, next the inducement of friends, and 10.9% of them smoked to get rid of stress. Their favorite place for smoking was in the order of the entertainment centers, schools, and private academies. They personally purchased cigarettes mostly at the store. Most of them smoked less than 5 cigarettes a day, but 3.7% smoked more than a pack of cigarettes a day, usually with friends rather than alone. Second, the ratio of drinking was relatively high 78.1%, and their initial drinking experience was most frequent at the third year of the middle school. The initial motive of drinking was mostly curiosity and the inducement of friends, but 10.7% of them started drinking to reduce stress and anxiety. The places for buying alcohol and drinking were bars or restaurants. The ratio of habitual drinking was 45.1%, and the ratio of irregular drinking was 53.3%. 1.8% of the drinking students enjoyed drinking everyday. The amount of drinking varied from half a bottle to two bottles of Soju, and the drinking problem was serious to see that 11% of them drank more than two bottles at a time. Because 84.4% drank in groups with friends, a thorough and systematic supervision and education of the peer group drinking is essential. Third, as for the relationship between personal matters and smoking, it was found that there was a positive relation between smoking and sex, but there was no correlation between smoking and school years. Adolescent smoking was also related with scholastic achievement, the number of friends, and the existence of parents. Fourth, as for the relationship between personal matters and drinking, it was found that there was no correlation between drinking and sex, but there was a positive relation between drinking and school years. Fifth, the average index of stress was students themselves(2.58), school life(2.53), family life(2.19), friends(2.00), and the total index of stress was 2.33. Sixth, there appeared a marginal negative correlation between stress and 'drinking and smoking' in Pearson coefficient of correlation r to see the influence of stress on smoking and drinking. The difference of the average index of stress according to smoking and drinking bears meaningful difference for all students, smokers and non-smokers, drinkers and abstainers in students themselves, school life, family life, friends, and total stress. Smoking has an effect on family life most, school life next, and drinking has an effect on school life most, family life next, with the explanation power of 11% and 9% respectively, in a regression analysis to analyze the factors influencing on smoking and drinking among the factors of stress.

민담 <목도령>의 줄거리를 간단히 소개하면 다음과 같다. 목도령은 선녀와 나무의 아들로서 아버지·나무의 도움으로 홍수에서 살아남은 뒤 홍수에서 구해준 사내아이와 함께 세상에서 가장 높은 봉우리에 있는 할머니의 집에서 머슴살이를 하게 된다. 할머니에게는 친딸과 의붓딸이 있었는데 홍수에서 구해준 개미와 모기의 도움으로 목도령은 할머니의 친딸과 결혼하고 사내아이는 의붓딸과 결혼하여 두 쌍의 부부가 되어 새 인류의 조상이 되었다는 내용이다. 대상민담을 해석하기 위하여 먼저 중심적인 모티브인 나무의 의미를 확충하여 나무가 자기와 리비도의 상징이며 탄생의 주체인 동시에 세계수이자 지혜를 의미하고 이러한 나무의 정령과 천상의 선녀사이에서 탄생한 목도령은 '신성한 아이'로서 무의식의 원형을 인지하게 되는 잠재력의 출현으로 보았다. 선녀·어머니가 7~8세에 사라짐은 최고의 선(善)에 이르기 위해서 거쳐야 하는 필수적인 조건이고 여성성의 부재에서 출현한 홍수는 무의식의 보상작용으로 보이며 대상 민담에서 홍수를 징벌이 아닌 자연현상으로 보는 점은 만물자화(萬物自化)의 도가사상에 바탕을 둔 동양의 정신사적 배경과 관련이 있지 않나 생각되었다. 남근적인 나무가 홍수와 함께 쓰러지고 여성성적인 배의 역할을 하는 것은 시대의 조류로 가부장적 체계가 붕괴되고 전체를 향하게 된다는 의미와 연관된다고 보았고, 물에서 구해낸 개미와 모기는 본능의 상하(上下)양면을 대변하며 신성을 매개하고 있고, 그들이 도움을 준다는 것은 무의식에서 도움이 온다는 것이다. 홍수에서 구한 사내아이는 수면상태에 있던 삶의 부분이 깨어나 양극의 긴장을 삶 속에서 경험하는 것과 연관되고, 아이들을 키워서 새 인류의 조상이 되게 하는 할머니는 국모신이자 태모의 상징으로서 전체성에 이르게 하는 무의식의 근원적 조절자이다. 두 아이의 머슴살이와 할머니가 목도령에게 준 이니시에이션의 시련은 의식의 수준을 낮추어야 무의식이 활성화되며 무의식의 도움으로 통합이 실현된다는 목적의미를 가지며, 조과 모래, 동쪽과 서쪽을 구별하는 작업은 합일을 위해서 먼저 분리를 해야 한다는 것과 연관된다. 두 쌍의 남녀 사위(四位, quaternity)가 새 인류의 조상이 된다는 것을 전체를 의미하는 숫자 4에서 정신의 중심이 생기면서 갱신으로 이어진다고 보았다. 저자는 또한 대상 민담에 나타난 여러 다른 사위의 구조를 추정하여 그 상징적 의미를 융의 자기의 구조에 관한 생각을 중심으로 고찰하였다. 이 민담에서 주목할 것은 목도령과 할머니의 친딸, 동(東)방의 양성적(陽性的)인 측면뿐 아니라 그 대극에 해당하는 의붓딸, 서(西)방, 그리고 목도령의 그림자로 이루어진 음성적(陰性的) 측면을 함께 인류 조상의 두 쌍으로 정했다는 점이다. 그러나 이 둘 중에 양성적인 측면인 선(善)한 면에 더 무게를 두고 있지 않나 생각된다.
