Background: Airag, alcoholic sour-tasting beverage, has been traditionally prepared by Mongolian nomads who naturally ferment fresh mares' milk. Biochemical and microbiological compositions of airag samples collected in Ulaanbaatar, Mongolia and physiological characteristics of isolated lactic acid bacteria were investigated. Methods: Protein composition and biochemical composition were determined using sodium dodecyl sulfate-gel electrophoresis and high performance liquid chromatography, respectively. Lactic acid bacteria were identified based on nucleotide sequence of 16S rRNA gene. Carbohydrate fermentation, acid survival, bile resistance and acid production in skim milk culture were determined. Results: Equine whey proteins were present in airag samples more than caseins. The airag samples contained 0.10-3.36 % lactose, 1.44-2.33 % ethyl alcohol, 1.08-1.62 % lactic acid and 0.12-0.22 % acetic acid. Lactobacillus (L.) helveticus were major lactic acid bacteria consisting of 9 isolates among total 18 isolates of lactic acid bacteria. L. helveticus survived strongly in PBS, pH 3.0 but did not grow in MRS broth containing 0.1 % oxgall. A couple of L. helveticus isolates lowered pH of skim milk culture to less than 4.0 and produced acid up to more than 1.0 %. Conclusion: Highly variable biochemical compositions of the airag samples indicated inconsistent quality due to natural fermentation. Airag with low lactose content should be favorable for nutrition, considering that mares' milk with high lactose content has strong laxative effect. The isolates of L. helveticus which produced acid actively in skim milk culture might have a major role in production of airag.

The purpose of the study was to examine the effect of sex role orientation on the amount of time spent in meal preparation and cleanup, clothing care, and indoor cleaning accomplished by husbands and wives in couple-headed households in the U.S.. The overall research hypotheses examined were : (1) there is a relationship between demographic and socioeconomic characteristics of the husband and wife and the sex role orientation of the husband and wife; (2) for both husbands and wives, there is a relationship between sex role orientation and the amount of household production time that is accomplised by each individual; and (3) the relationship between sex role orientation and the amount of household production time remains when demographic and socioeconomic factors are controlled. The 1981 data from the 1975-1981 Time Use Longitudinal Panel Study collected at the University of Michigan were used for this study. The major findings is that a relationship between sex role orientation and the amount of time spent in three household production activities was not found, when all independent variables were controlled. That is, sex activities was not found, when all independent variables were controlled. That is, sex role orientation was not a predictor affecting the amount of time that husbands and wives spend on meal preparation and cleanup, clothing care, and indoor cleaning.

Foundation Beyeler museum located near Basel, Switzerland is one of the most-visited art museum of the world. Although the entire volume of the museum is not huge, its art collection as well as the well-known museum building designed by Renzo Piano deserve to attract many visitors. The initial design was started in 1991 when the city of Basel decided to fund and support the project. Through a couple of design stages, the museum was finally opened to public in 1997. There have been various research papers dealt with general design issues of Beyeler museum such as composition of exhibition spaces, and natural lighting. However, this paper aims to study the design methods and relationship between art, architecture and nature. Although the museum building is located on the site quietly, there are various specific design solutions to create unique spatial experience of art and nature at each parts. This study focuses on 4 parts of the museum that are located on the main circulation. How art, architecture and nature are integrated together is the main target of the analysis. The analysis is based on visual-perceptual experience and spatial configuration. In chapter 2, general background of the project was studied. In chapter 3, characteristics of the site's natural environment and Piano's design concept's were examined. In chapter 4, each parts were analyzed in detail with diagrams. In chapter 5 & 6, the spatial characteristics were compared together and the fundamental role of the museum architecture was concluded.

In this study, the characteristics and patterns of family problems were explored. What constituted family problems, and how those evolved over the period of drastic changes in the Korean society were examined, by analyzing articles published from the 1940s to the 1980s in the four major national newspapers in Korea. A total of 6542 articles related to family problems in the four newspapers, Chosun, Dong-A, Kyunghyang, and Seoul, were used for the content analysis of this study. The main categories of family problems were classified as poverty, marital issues, issues related to children and adolescents, elderly issues, problems in the family as an institution, and the so-called family-lag problem. Each of these categories consisted of several subcategories: The poverty-related problems included the problems caused by difficulty in making a living and instability of living, for example. The marital issues category consisted of conflicts between the couple, unfaithful spouses, domestic violence, divorce, and so on. Issues related to children and adolescents included juvenile delinquency, difficulty in bringing up children, child abuse, single motherhood, and underage household heads, for example. The elderly issues included the anxiety over the aging society, support for the elderly, conflicts between mother-in-law and daughter-in-law, alienation of the elderly, etc. Problems in the family as an institution consisted of the legal issues in such areas as marriage, succession of the family head, and adoption. Lastly, the family-lag problem included confusion over family values, and conflict caused by the inconsistency between consciousness and actual behavior related to the family or family crisis. From the 1940s to the 1980s, family-lag was the most common problem (26.2% of the total articles), followed by issues related to children and adolescents (23.1%), poverty (16.2%), marital issues (15.9%), elderly issues (12.4%), and problems in the family as an institution (6.0%). During the 1940s and the 1950s, poverty was a prominent problem, and in the 1960s, issues related to children and adolescents were most commonly addressed in the articles. In the 1970s and the 1980s, the family-lag problem was the most frequently addressed.

The consumer affair is one of the rapidly evolving problems in the process of recent economic growth. As the society and its economy changes, the nature and the scope of the consumer affairs also changes. while the main concept of the consumer affaires originated from the market mechanism, it is now expanding beyond the market mechanism to include everyday lives of consumers. In solving the problems which arise form the status difference between the manufacturer and the consumer the manufacturer's action is no less important the consumer's self-improvement of its status. The manufactures with the purpose of getting maximum profits from the consumers are conducting the consumer oriented managerial marketing, but this sis done form the manufacturer's point of view with the consumer's position being neglected. It is the purpose of this paper to investigate the nature and direction of the marketing from the consumer's position being neglected. It is the purpose of this paper to investigate the nature and direction of the marketing from the consumer's point of view. For this study a couple of pre-investigations were done. First, I surveyed the changing consumers with economic growth the developing process of marketing, and the cause and characteristics of the today's consumer affaires. Second, I studied the concept change of the modern marketing, and the concept of the consumerism which was materialized by this concept change. I further studied, with the consumer's point of view, the socioecological marketing which is based on the consumerism. The conclusion of this investigation is that the manufacturers should convert the in humanized marketing to the more human and environment conscious socioecological marketing because the consumer affairs which arise from the mass consumption of the modern days are expanding to include everyday's problems. This conversion naturally should be based on the human concept based consumerism. To be more effective, the manufactures should assume more social responsibilities and conduct the socioecological marketing voluntarily and willingly.

Background: In Korea, the population is rapidly aging, and the types of households for the elderly are also diversifying. The self-rated health of the elderly is a valuable health indicator that can comprehensively represent the overall quality of life along with physical, mental, and functional health. On the other hand, studies on the association between household type and self-rated health of the elderly are still insufficient. Thus, this study analyzed the association between household type and self-rated health by gender in Korean older adults. Methods: Using data from the analysis of the National Survey of Older Koreans 2017, 10,299 elderly people aged 65 and over were targeted. For the accuracy of the analysis data, 9,910 people were selected as the study sample by excluding proxy responses, those diagnosed with dementia, and non-response. And technical analysis, univariate analysis using the Rao-Scott chi-square test, and logical regression analysis involving survey characteristics were conducted by gender. Results: According to the adjusted model with all variables, in both men and women, the odds ratio of self-rated health 'bad' in 'couple (with ill spouse)' was significantly higher than 'couple (with spouse)'. It was 2.54 (95% confidence interval [CI], 2.05-3.15) for men and 2.11 (95% CI, 1.70-2.62) for women. In addition, the odds ratio of self-rated health 'bad' in 'living with adult children' was 1.43 (95% CI, 1.09-1.87) for men and 1.42 (95% CI, 1.15-1.75) for women, which was more significant in women than men. Conclusion: This study states that there is an association between gender, household type, and self-rated health of the elderly, and the health of a spouse and cohabitation with children have a significant effect on self-rated health. As a result, in order to improve the health status of the elderly, health promotion and health care policies involving the characteristics of the elderly's gender and household type are needed.

This study deals with a counseling case in which a mother requested counseling due to the problems of her daughter, who suffers from multiple tic disorder. The participants of this study included five family members (grandmother, father, mother and two female children) and a total of 23 sessions were held from September 2006 to December 2007. Additional counseling ($24^{th}$ counseling session) was conducted on April 1st, 2009. The data was based on recorded transcripts and notes from 24 family therapy sessions. The study used a constant comparative analysis, which uses matrix and network display as an analysis method suggested by Miles&Huberman(1994). The characteristics of the family of origin and the indifference of the husband had caused the wife stress. The couple had frequent conflicts due to dysfunctional communication methods, a clash of values, sexual dissatisfaction, and a lack of communication. This marital conflict became the primary factor of the daughter's multiple tic disorder. Intervention of the family therapist resulted in the setting of treatment goals based on MRI's communication theory and Bowen's family systems theory in order to solve the problem of the daughter's multiple tic disorder. Also, the therapist's intervention techniques included exploring experiences with the family of origin, shedding light on the multigenerational transmission process, exploring dysfunctional attempts at solutions, the therapist's self-disclosure, providing similar cases, dealing with resistance, and suggesting a new communication method. To solve the problem, the therapist helped the family separate the daughter spatially from her parents. Therefore, the therapist's intervention helped reduce the daughter's tics and improve relationships among the family.

For the safety of aircraft and accuracy of bombs, many companies have researched the new concept of adaptive kit to flying-bombs. For the long distance flying, it's normally used deployed high-aspect ratio wing because of limited volume. The probabilities of large elastic deformation and flutter are increased due to decreased stiffness of high-aspect ratio wing. In this paper, computational fluid dynamics and computational structure dynamics interaction methodology are applied for prediction of aerodynamic characteristics. FLUENT and ABAQUS are used to calculate fluid and structural dynamics. Code-bridge was made base on the compactly supported radial basis function to execute interpolation and mapping. There are some differences between rigid body and fluid-structure interaction analysis which are results of aerodynamics characteristics due to structural deformation. Small successive vibration was observed by interaction.

The prolongation of life expectancy has expanded the duration of marriage in old age. In the meanwhile, the change of life style emphasizing privacy and sociodemographic environment favoring independent living has increased the number and proportion of the elderly living with spouse only. This study, focusing on those aged 60 and over who live with spouse only the elderly, explores their marital relationship. The study pays a special attention to compare whether and how the satisfaction on the relationship with spouse would differ between husband and wife. The ordered logit model analysis is conducted based on the nationwide survey '2008 Korean National Survey of Welfare Need in the Elderly'. The results show that the marital relationship satisfaction of husbands is influenced by their own characteristics but hardly affected by his wife's. In contrast, the satisfaction of wife is influenced by husband's characteristics as well as hers. These finding reflect that women are more strongly family-centered and dependent on their husband.

In tunnel, though the frequency of fire occurrence is relatively lower than other structures, the characteristics of sealed space tends to cause the temperature to rapidly rise to more than $1000^{\circ}C$ within 5minutes after fire, which might eventually lead to a large fire that usually results in a loss of lives and the damage to the properties, not to mention a huge cost necessary for repair and maintenance after fire. We have developed various conditions of the heating furnace and the method to install a thermo couple within the furnace based on EFNARC and KS F 2257-1. Referring to tunnel fire scenarios, it clarified the heat transfer characteristics of concrete PC panel lining depending on fire intensity (ISO, $1^{\circ}C$/SEC, MHC, RWS), and to identify the range of thermal damage, the evaluation was carried out using ITA standard. As a result, 30mm under ISO fire condition, 20mm under $1^{\circ}C$/SEC, 100mm under MHC and 50mm under RWS were measured. And when it comes to spalling, 30mm was measured under RWS and MHC.
