The purpose of this study is to examine the effects of job-related characteristics on alcohol consumption among female workers. The Data was collected from a sample of 1,000 female workers by a stratified proportional quota sampling method derived from those who were working in Seoul. Drinking behavior pattern includes total amount of pure alcohol consumed during the last month (AC) measured by graduated quantity-frequency. Job-related characteristics (JRC) were measured by job-related stress, work characteristics, and organizational structure including length of working hours, number of times dining out together with workers per year, number of staff to supervise, employment status, occupational category, and proportion of female workers to male counterpart. Confounding variables include sociodemogrphic and socio-cultural attitudes toward alcohol expectancy, subjective norm of drinking, and gender-role attitude. Hierarchical multiple regression models show that the variability of AC was accounted for by some JRC including number of times dining together and employment status, with confounding variables held constant. However, the relationship between AC and JRC varied across occupational categories. Some implications were discussed in terms of health policy for female workers and further study for female drinking behavior.

The purpose of this study is to analyse the factors affecting rehabilitation of physically disabled persons . Data were collected from 118 physically disabled persons who were registered at facilities for disabled persons by an interview surevey Conducted from October 17 to October 26, 1988. The three facilities for the survey were selected by stratified random sampling. The results were as follows : 1. Using factor analysis, 10 variables were-grouped into 4 factors : physical need, need for social problem-solving, need for social interaction and educational need. The proportion of variance explained by these factors was $58.3\%$. 2. Age, religion and job were significantly related to the functional life scale score, but other variables were not. 3. Family APGAR score and severity of disability were significantly rotated to the functional life scale score. 4. From the multiple regression analysis on rehabilitation of the physically disabled person, the following: three variables were statistically significant : age, severity of disability and family functioning. These results suggest that age, severity of disability and family functioning variables are important factors for rehabilitation of physically disabled persons. Since the family functioning variable can be controlled by care, rehabilitation team should monitor the variable closely to improve the efficiency of rehabilitation. Because of their implication for further study, some variables, other than those considered here, are needed for studying rehabilitation of physically disabled persons.

The objective of this study was to evaluate associations between airborne manganese and blood manganese in a general population of South Korean adults. The concentrations of airborne manganese in total suspended particulate (TSP) were calculated from data obtained from ambient air-monitoring stations (AAMSs) located in South Korea. Blood manganese data obtained Korean National Health and Nutrition Examination Survey (KNHANES) using a rolling sampling design involving a complex, stratified, multistage, probability cluster survey of a representative sample of the non-institutionalized civilian population of South Korea. Airborne manganese geometric means was 46.10 $ng/m^3$, blood manganese geometric means were 1.19 ${\mu}g/d{\ell}$ for male and 1.40 ${\mu}g/d{\ell}$ for female. In multiple linear regression analysis of log transformed blood manganeseas a continuous variable on airborne manganese, after adjusting for covariates including gender, age, job, smoking and drinking status, education level, BMI (body mass index). Airborne manganese was positively associated with blood manganese with statistical significance. The present study confirms that airborne manganese is a possible contributor to the increase of blood manganese in the adult general population.

The purposes of this study were to analyze the consciousness of the professors and college students about the fashion industry internship and to provide basis data which were to develop an internship program of the fashion company and university and to activate it. The whole country were classified as Seoul and Gyeonggi division, Gangwon division, Chungchung division, Yeongnam division, and Honam division for this study. As object of the questionnaire, the professors of 50 universities and 132 college students from every division were selected by stratified cluster sampling. The investigation tool for this study was composed of 95 items for two kinds of professor's and two kinds of college student's survey. The question results were analyzed by frequency analysis and variance analysis, t- test and f- test by spss 10.0. The contents of research result were as follows : First, it arranged the opinions of the college students and professors about the internship experience and execution reason, the internship application methods and execution contents, the type of preference company and worked company, the company education contents, internship evaluation and postmortem.

This study investigated the extend to which the facilities satisfactorily accommodate people with different disabilities and their specific needs for improving the facilities. Systematic interviews were conducted with 90 disabled people using the non-propertionate stratified cluster random sampling method. Frequency analysis, Chi-square tests, Duncan tests, and analysis of variance(ANOVA) were employed for data analysis. The findings indicated that the respondents' assessment of accommodations and needs for improving accommodations differed by the type of disabilities. People with physical disabilities were the least satisfied with stairs, followed by seating in stadiums and/or theaters. For people with visual disabilities, the lack of guidance and information facilities was the most difficult problem. People with hearing disabilities often pointed out difficulties in using public telephones. meanwhile, people with physical disabilities asked for easy access to assistive devices and improved mobility-related circumstances. yet people with visual disabilities expected to improve way-finding relevant issues, such as detectable warnings on walking surfaces and guidance and information facilities, whereas people with hearing disabilities desired to develop hearing-aid equipments, such as TDD and assistive listening systems.

인터넷을 통해 전송되는 트래픽의 양이 지속적으로 증가하고 있기 때문에 네트워크 트래픽 모니터링 시스템이 모든 패킷을 실시간으로 분석하기는 어렵다. 피어-투피어(P2P), 스트리밍 미디어, 메신저 등과 같이 동적으로 포트 번호를 할당받는 애플리케이션의 사용이 늘어나면서, 사용자들은 이들이 유발하는 트래픽을 분석하기를 원하고 있다. 이 같은 고수준의 분석을 위해서는 각 패킷마다 많은 처리 시간이 필요로 한다. 본 논문에서 부하 차단기를 이용하여 패킷의 수를 제한할 것을 제안한다. 선택된 패킷은 어떤 애플리케이션이 생성한 것인지 식별된 후, 정의된 애플리케이션 계층의 프로토콜에 따라 분석된다.
