본 연구는 청소년들의 시간제 노동경험이 비행경험에 영향을 미치게 되는 경로를 규명하고자 하는 목적으로 이루어졌다. 이를 위해 서울시내 고등학생 중 한 달 이상의 기간동안 시간제 노동을 경험한 학생 201명을 대상으로 자료를 분석하였으며, 주요 비행이론인 차별접촉이론, 사회통제이론, 권력자원이론에 기반하여 연구모형을 설정하고 구조방정식을 통해 이를 검증하였다. 그 결과, 청소년들의 주당 노동시간이 증가할수록 동료의 비행성향이 증대되고, 용돈의 소비수준이 증가하며, 학교적응 수준이 떨어지게 되고, 이것이 다시 비행수준에 영향을 미치는 것으로 나타나 세 가지 주요 비행 이론들이 적용될 수 있음을 검증하였다. 특히 주당 노동시간은 중비행보다는 경비행의 증가에 미치는 영향이 컸으며, 중비행의 경우 동료의 비행성향만이 유의미한 매개변인으로 확인되었다. 이러한 연구를 통해 주당 노동시간과 비행의 매개변인을 검토함으로써 비행의 증가를 막기 위한 개입지점을 찾을 수 있었으며, 이에 기반하여 노동경험 청소년들의 비행성향을 감소시키기 위한 학교, 가정, 노동현장에서의 실천방안에 대해 논의하였다.

This study was carried out with the purpose of capturing current state of Korean family life culture related to childrearing. The Questionnaire developed for this study in order to delineate the values and perceptions related to general childrearing practices in present Korean families consisted of 73 items concerning prenatal care and child birth, child caring and rearing, and role division and value education. Subjects were mothers of young and primary school children currenly residing in Seoul area and Choongchung province of South Korea. Four hundred and four questionnaires were analyzed, and the summary of results were as follows. First, both the respect for children's individual needs concerning food, clothing, and health-related behaviors and the pursuit of convenience in everyday life on the part of mothers appeared to be important and valued by Korean mothers. Second, the basic values and traditional meanings of family events such as prenatal care, children's birthday, especiall the first one, and family rituals and gatherings still appeared to be exsiting and influential, but there seemed to have been some changes both in their formal aspects and detail contents. Third, meaningful differences in childrearing attitudes were found according to mother's place of growth, educational level, and her employment status. Finally, traditional distinction between sexes and sex-role division in childrearing seemed to have weakened to some extent, which was particularly among mothers with higher educational level or residing in big cities.

This study focuses on the life experience of married women in their 30s to 40s who have experienced parental divorce. For a comprehensive understanding towards the women, this study takes a life history research approach. The participants of this research are 8 women who have experienced parental divorce and are now married with children. The data were gathered through in-depth interviews and were analyzed through the spiral of analysis, following the process of Wolcott's "description, analysis, and interpretation." The results of this study are as follows. First, participants experienced emotions such as fear, anger, and lack of affection. Second, parenting attitude and parental divorce had negative effects on the participants' formation and development of self concept and in turn, participants experienced anxiety and withdrawal from interpersonal relationships. Some had difficulties in concentrating on their schoolwork, which was caused by psychological effects from their instable home environments and some were negligent at school due to their parents' indifference or as an act of rebellion towards them. Third, although participants displayed interest towards the opposite sex, fear towards the opposite sex or unrealistic expectations led to difficulties in forming relationships. Participants also confessed that although they married so that they could escape their original family and form a new happy one, they experienced a rocky start at the beginning of their marriage. Fourth, parental divorce had a lifelong impact on children. Even after the children became adults, parental divorce affected each key stage of transition in life such as dating, choosing one's spouse, marriage, and child rearing. Fifth, participants displayed a strong attachment to life under the assumption that only they themselves can be depended on. This led to their strong commitments to a successful marriage without the possibility of divorce. In conclusion, parental divorce is not a transitory or incidental event. Rather, it becomes a part of the children's lives with lifelong implications.

With regard to the pavilion buildings of Imcheonggak Gunjajeong and Donglakdang Gyejeong that are located within residential areas, this study focused on the construction background, the building owner's circumstances and the location environment of these buildings, and attempted to derive the architectural characteristics presented by these two pavilion buildings and, through this, to grasp the architect's intention of plan. The results of this study are as follows. With regard to Gunjajeong, it could be confirmed that, first, it is located in a propitious site and took the composition that follows the family ritual standards for the family rituals of the scholar-gentry class and opens to visitor access, and second, the floor height of the site and interior space was designed so that Munpilbong on the south and the Sarangchae on the west, and the Sadang on the east can be connected visually, and third, the authority and dignity of the head family were built through the symmetric 丁-shaped plane figure, the wide partition module, the form-centered building, and the hierarchical composition of the roof. On the other hand, with regard to Gyejeong, it could be confirmed that, first, it is located along the stream of Jagye valley that has no mountains in the front and in the back and took the composition that put the name symbolizing Taoist thoughts on the surrounding natural environment and was closed to visitor access but opens to nature, and second, with Jagye and Jagye surroundings as the main landscape, it built the concept of intended landscape that symbolizes the Taoist thoughts by giving names not only simply to the visible objects but also to surrounding rocks, and third, the asymmetric ㄱ-shaped plane composed a yard-centered space rather than emphasizing the shape, and connected the part of the plane with Jagye so as to be embodied as a personal inner self-perfecting place that closely communicates only with nature away from the mundane world.

The purpose of this study was to categorize the contribution evasion and develop the expected models for contribution arrears in National Health Care System. The modified logistic regression model in non-payments was used as logistic regression model based on the statistical method. By using this model, we arranged non-payment types and typical branches those are appeared by statistical technique. First fact, sex and age branches those are able to take a part in economy had effect mostly. Also they had difference in non-payment probability by existence of their incomes and property. Especially people who didn't have their own house and car were appeared in high non-payment probability, disease and reduction characteristic(rare diseases, reduction of seniors, handicaps, numbers of medical treatments) didn't effect much in probability. The reason for some characteristic of non-payment which is higher than the correct threshold value of Logistic Regression Model (a suggested model for predicting non-payment)'s distribution of probability was mostly moral hazard. Living difficulty was the bigger reason for non-payment, but moral slackening was the bigger reason for non-payment. But it is careless to decide that moral hazard is just the reason, there is a necessity to examine on the side of sociology based in family. By the reason, the member's non-payment reason can be classified by economy, population, and psychology, but there was a comprehension that losing of work desire could be one reason. So we analyzed informations for composition of family of members. In conclusion, we grasped that family conflict makes non-payment and conversion of member in the National Basic Livelihood Protection System difficult.

Thermoplasma acidophilum is a thermoacidophilic archaeon that grows optimally at $59^{\circ}C$ and pH 2. Along with another thermoacidophilic archaeon, Sulfolobus solfataricus, it is known to metabolize glucose by the non-phosphorylated Entner-Doudoroff (nED) pathway. In the course of these studies, the specific activities of glyceraldehyde dehydrogenase and glycerate kinase, two enzymes that are involved in the downstream part of the nED pathway, were found to be much higher in T. acidophilum than in S. solfataricus. To characterize glycerate kinase, the enzyme was purified to homogeneity from T. acidophilum cell extracts. The N-terminal sequence of the purified enzyme was in exact agreement with that of Ta0453m in the genome database, with the removal of the initiator methionine. Furthermore, the enzyme was a monomer with a molecular weight of 49kDa and followed Michaelis-Menten kinetics with $K_m$ values of 0.56 and 0.32mM for DL-glycerate and ATP, respectively. The enzyme also exhibited excellent thermal stability at $70^{\circ}C$. Of the seven sugars and four phosphate donors tested, only DL-glycerate and ATP were utilized by glycerate kinase as substrates. In addition, a coupled enzyme assay indicated that 2-phosphoglycerate was produced as a product. When divalent metal ions, such as $Mn^{2+},\;CO^{2+},\;Ni^{2+},\;Zn^{2+},\;Ca^{2+},\;and\;Sr^{2+}$, were substituted for $Mg^{2+}$ the enzyme activities were less than 10% of that obtained in the presence of $Mg^{2+}$. The amino acid sequence of T. acidophilum glycerate kinase showed no similarity with E. coli glycerate kinases, which belong to the first glycerate kinase family. This is the first report on the biochemical characterization of an enzyme which belongs to a member of the second glycerate kinase family.

Background: The rates of breast cancer have increased over the past two decades, and this raises concern about physical, psychological and social well-being of women with breast cancer. Further, few women really want to do breast cancer screening. We here investigated the socio-demographic correlates of mammography participation among 400 asymptomatic Iranian women aged between 35 and 69. Methods: A cross-sectional survey was conducted at the four outpatient clinics of general hospitals in Tehran during the period from July through October, 2009. Bi-variate analyses and multi-variate binary logistic regression were employed to find the socio-demographic predictors of mammography utilization among participants. Results: The rate of mammography participation was 21.5% and relatively high because of access to general hospital services. More women who had undergone mammography were graduates from university or college, had full-time or part-time employment, were insured whether public or private, reported a positive family history of breast cancer, and were in the middle income level (all P<0.01).The largest number of participating women was in the age range of 41 to 50 years. The results of multivariate logistic regression further showed that education (95%CI: 0.131-0.622), monthly income (95%CI: 0.038-0.945), and family history of breast cancer (95%CI: 1.97-9.28) were significantly associated (all P<0.05) with mammography participation. Conclusions: The most important issue for a successful screening program is participation. Using a random sample, this study found that the potential predictor variables of mammography participation included a higher education level, a middle income level, and a positive family history of breast cancer for Iranian women, after adjusting for all other demographic variables in the model.

Korean Government has developed Sejong City as a new administration city. This city of future was planned and designed toward one of the most eco-friendly city on the basis of ICTs. To attain this object, a carbon emission monitoring system (CEMS) was designed and installed as a part of u-city service which provides various information anytime and anywhere to enrich the people's quality of life. In this paper, at first, the structure and functions of CEMS are introduced. This system is consist of 5 parts - data collection from user and linked public DBs, transforming data into meaningful information for the policy makers, system-user interfacing via statistical tables and graphs, and system maintenance. This system can be operated by the citizen participation through whole the process. With the help of GIS map and graphic interface, statistics of monitored data for both citizen and decision maker provided and after feed-back, they have affected on the behaviour of citizen's energy consumption and related policy as well. By the CEMS, energy consumption data of 124 agreed households were collected during 9 months in 2012. Electricity, gas and water consumption were remote-metered automatically by the system and analysed. This showed that more than 85% of CO2 emission is rely on electricity usage. Furthermore, number of family members and size of house influences on the emission of CO2 by each household together with the life-style of the occupants. Electricity and water consumption showed the seasonal factor while gas consumption represents the number of family members. Even this paper has limitations caused by 9 months of data collection, it shows the policy directions to reduce the emission of CO2 focusing on the house size and number of family members of each households. With the result of this research, life-style of the generation of dwellers should be investigated and the CO2 emission characteristics of other housing type as well for the data building for future policy making.
