The purpose of this study was to find out the amount of the household work time related to food and examine the factors affecting the time accomplished by married female home-based workers and on-site workers. The data were collected from 165 married female home-based workers, and 292 married female on-site workers in Pusan and Kyungnam province, by the self-administered questionnaire. frequency distributions, Cronbach's alpha, t-tests, Pearson's correlations, and multiple regression analyses were conducted by SPSS/PC+. The major findings of this study were as follows: (1) both married female home-based and on-site workers spent more time on household work related to food in a weekend than in a weekday, (2) in a weekday, occupation was significantly related to the amount of time that married female home-based workers spent on food household work, whereas age and occupation were significant for married female on-site workers, (3) on Saturday, the significant factors of the time spent on food household work were the number of family and occupation for married female home-based workers, and educational level, occupation, sex role attitude, existence of children of 6 years or under, and existence of elders/disability within the family for married female on-site workers, and (4) on Sunday, for married female home-based workers, the number of family, occupation, and the level of market good substitution had significant effects on the amount of time spent on food household work, and for married female on-site workers, age, the number of family, occupation, sex role attitude, work hours on Sunday, and the level of market good substitution were significant.

Comparison of different morphological characteristics of bivalves is very useful for distinguishing species. Therefore, this study used a morphometric approach to document patterns of phenotypic change through the specimens of family Pinnidae inhabiting the bottom sediments at the coasts of An Thoi Archipelago (south-eastern Gulf of Thailand), in that way excluding intraspecific variations among different populations along a wide geographical range. It was revealed that individuals determined as Pinna trigonium separated from specimens of Pinna nigra and Atrina vexillum at high level, but P. nigra and A. vexillum were the single species A. vexillum, as it is assumed now. Also, it was found that both groups of P. trigonium individuals and A. vexillum specimens divided into tree subgroups unified the specimens with the similar morphometric parameters: small, medium and large within the populations, though there were no evident divisions into subgroups in the size distributions of the populations. In addition to the interspecific morphological variations, the species also showed significant intraspecific morphological variations even in the same population. Most probable reason for the appearance of the intraspecific morphological variations and division of all specimens into size-specific subgroups in the population is the fact that the growth of Pinnidae bivalves is not isometric.

This paper deals with the reliability analysis of a complex system, which consists of two subsystems A and B connected in series. Subsystem A has only one unit and B has two units $B_1$ and $B_2$. Marked process has been applied to model the complex system. Present reliability model incorporated two repairmen: supervisor and novice to repair the failed units. Supervisor is always there and the novice remains in vacation and is called for repair as per demand. The repair rates for supervisor and novice follow general and exponential distributions respectively and the failure time for both the subsystems follows exponential distribution. The model is analyzed under "Head of line repair discipline". By employing supplementary variable technique, Laplace transformation and Gumbel-Hougaard family of copula various transition state probabilities, reliability, availability and cost analysis have been obtained along with the steady state behaviour of the system. At the end some special cases of the system have been taken.

이 논문에서는 일반화가중선형모형이라는 새로운 형태의 선형모형을 제시한다. 일반화가중선형모형은 설명변수와 반응변수의 관계를 설명분포함수의 선형결합이 반응변수의 평균에 대한 연결분포함수를 통해 모형화 되는 형태를 가지는 것으로 가정한다. 이모형은 일반화선형 모형에서 연결함수를 선택할 때 발생할 수 있는 모수공간과 선형 예측값의 공간이 일치하지 않을 수 있다는 문제가 발생하지 않고 모수에 대한 해석이 용이하다는 장점이 있다. 이 논문에서는 설명분포함수와 연결분포함수를 선택하는데 있어 발생할 수 있는 문제와 해결책에 대해 알아본다. 또한 모형에 포함되어 있는 모수를 추정하는데 고려해야 할 주의 사항과 이 사항들을 고려한 최대가능도추정법과 재표집 방법을 이용한 구간추정과 가설검정에 대해 알아본다.

General practitioners, internists, pediatricians, and family physicians are classified as so-called primary care physicians in the United States. We carried out this study for the purpose of answering the following question; "Who are the primary care physicians in Korea\ulcorner" We analyzed the 663, 154 claims which were drawn from the health insurance processing file made during the period of one month, April 1992 on the basis of systemic random sampling technique. The 663, 154 cases were matched with the doctor's file registered at the National Federation Medical Insurance by using the indivisual physician code number and analyzed according to the kind of specialty. If we follow the Geyman's definition of primary care physician in the United States, this study shows that they can take care of 43.2% of the total private clinic's claims in Korea. Provided that general practitioners and family physicians are considered the same way as in the United Kingdom, they could with only 8.3% of the total claims in Korea. The most frequent diseases are those which rank first to 46th in the total private clinic's claims. The proportion of the most frequent diseases was highest for pediatricians(90.4%) and followed by internists(81.4%), otolaryngologists(78.7%) and family physicians(76.5%). The proportion of the most frequent diseases in the most common 46 diseases was highest for radiologists(80.4%) and the next was as follows : general practitioners(78.3%), family physicians(67.4%), and internists(67.4%). We classified the most common 20 diseases of each specialty into 17 categories of ICD-9 and compared it with those of general practitioners. The specialists who had managed a similar disease pattern to those of general practitioners were identified as anesthesiologists, family physicians, general surgeons, and internists. Some specialists practicing at private clinics managed the diseases which were not quite appropriate for their specialties. After we evaluated each specialty by the most common diseases, the most frequent diseases, and the most frequent 20 diseases of each specialty in terms of the 17 categories of ICD-9, a tentative assumption is made that the primary physicians in the Republic of Korea are general practitioners, anesthesiologists, family physicians, internists, and general surgeons. This study has concluded that the categories of the primary care physicians are so diverse that their roles and distributions are distorted accordingly. Vigorous health policy efforts in correcting the malcomposition need to be made for the better provision of primary health care in Korea. in Korea.

Purpose: The study aimed at identifying distributions of career stress and determining whether conflict at school or with family and health-risk behaviors could be associated with career stress. Methods: The subjects were 7,155 high school students in Seoul. Data were stratified random samples from Seoul student health examinations in 2010. Chi-square, trend test and multiple logistic regression were conducted. Results: Fifty six percent of subjects had career stress. Career stress, after adjusting for confound variables was associated with a significantly increased odds ratio (OR) for sociodemographic characteristics including females (OR=1.34), 12th graders (OR=1.56), 11th graders (OR=1.50), south area (OR=1.47), and northeast area (OR=1.40), for conflict at school or with family including violent threats made by family members or schoolmates (OR=2.00), thoughts of running away from home (OR=1.45), and needing of counseling for agony (OR=5.45), and for health-risk behaviors including sleep ${\leq}6$ hours/day (OR=1.23), nonuse of seat belts or protective euipment (OR=1.50), and frequently viewing pornography or chatting on adult Web sites (OR=1.23). Conclusion: Stress-coping skills and intervention strategies will be needed to enhance students' positive and to help them cope with psychosocial conflicts at school and with their families, and with health-risk behaviors, including sleep deprivation and nonuse of safety measures, including seat belts and protective.
