This study analyzes marriage and fertility rates in Korea and makes recommendations for family policy. Based on the 'The Report of Marriage & Divorce Statistics in 2005' and data from the Korea Statistical Information System (KOSIS) of the National Statistics Organization, the trends, reasons for marriage rates changes, and future expectations were critically reviewed. In addition, the relationship between marriage and fertility rates was analyzed. The principle characteristics of marriage rates are as follows: 1) the M-shape of the longitudinal crude marriage rates; 2) the increased age of individuals entering their the first marriage; 3) the increase in remarriage rates; 4) the changes in the patterns of remarriage; 5) the increased in the age at which individuals remarry and; 6) the increase in marriage to non-Koreans. The marriage and fertility rates changes are a permanent normative shift because of 1) later marriage because of women's increased education and labor force participation 2) rational choices about birth control 3) reduced population because of the aging of baby boomers 4) structural changes in the marriage market and 5) egalitarian changes in women's attitudes toward marriage and family. The recommendations for future family policy were as follows: 1) the need for a realistic, long-term family policy because the current marriage patterns will continue; 2) the need to develop new statistics such as fertility rates that are based on marriage cohort or birth cohort because family behavior is a mixture of personal, social and political responses; 3) the need for impact analysis of current family policy about increasing fertility rates; 4) the need for a new family perspective that encompasses diverse marriage and family patterns; 5) the need to focus on men's role in families because of women's changing roles and family interaction patterns and; 6) the need for preventive family policies such as family life education.

지난 몇 년간 무선 개인 거리 네트워크는 (WPAN)는 다양한 건강관리 응용분야에서 널리 연구되어왔다. 그러나, 하드웨어 장치의 한계성으로 인해 WPAN의 효용성에 대한 문제점이 도출되었다. 이를 개선하고자 무선 인체통신 네트워크 (WBAN: Wireless Body Area Network)의 개념이 탄생하였고 이러한 WBAN을 위하여 다용도의 MAC계층 프로토콜을 설계할 필요성이 대두됐다. 더불어, 환자에게 긴급 상황이 발생했을 경우, 최종 목적지로 긴급메세지가 전해지는 우선권을 가진 메커니즘이 필요하게 되었다. 본 논문은 WBAN을 위한 복합 우선순위 MAC이라 일컬어지는 우선순위 메커니즘에 대해 기술한다. 또한, 시뮬레이션의 확장을 통해, 평균 패킷 지연 시간을 최소화 할 수 있는 MAC 프로토콜을 제안한다. 이들을 통해, 환자에게 긴급 상황이 발생했을 때 충분한 도움시간과 의학적 치료지원 시간이 제공 될 수 있도록 한다. NS-2를 기반으로 한 성능평가 시뮬레이션을 통해, 우리의 복합 우선순위 MAC의 뛰어난 성능과 유용성을 입증한다.

A missile defense system is composed of radars detecting incoming missiles aiming at defense assets, command control units making the decisions on weapon target assignment, and artillery batteries firing of defensive weapons to the incoming missiles. Although, the technology behind the development of radars and weapons is very important, effective assignment of the weapons against missile threats is much more crucial. When incoming missile targets toward valuable assets in the defense area are detected, the asset-based weapon target assignment model addresses the issue of weapon assignment to these missiles so as to maximize the total value of surviving assets threatened by them. In this paper, we present a model for an asset-based weapon assignment problem with shoot-look-shoot engagement policy and fixed set-up time between each anti-missile launch from each defense unit. Then, we show detailed linear approximation process for nonlinear portions of the model and propose final linear approximation model. After that, the proposed model is applied to several ballistic missile defense scenarios. In each defense scenario, the number of incoming missiles, the speed and the position of each missile, the number of defense artillery battery, the number of anti-missile in each artillery battery, single shot kill probability of each weapon to each target, value of assets, the air defense coverage are given. After running lpSolveAPI package of R language with the given data in each scenario in a personal computer, we summarize its weapon target assignment results specified with launch order time for each artillery battery. We also show computer processing time to get the result for each scenario.

Musculoskeletal disorder (MSD) problems have been increasingly reported in hospital sector but the problems were not addressed with respect to holistic aspects of the target population in Korea. Often, it is required to understand how MSD symptoms are associated with factors such as personal, work environmental and psychosocial stressors. To examine features of association between sets of MSD symptoms and the factors, a questionnaire survey was conducted in a university hospital. A 140-item questionnaire was developed and used for collecting information including factors (e.g., job/occupation, task/activity, job stress) and MSD symptoms. A total of 1,091 workers (male 23.7% and female 76.3%) were finally determined for data analyses. Prevalence rate for the whole body was 72% and, among body parts, the highest was 48.7% for the shoulder, followed by 34.6%(the low back), 32.7%(the leg/foot), 27.9%(the neck), 26.7%(the wrist) and 12%(the elbow). The symptoms were significantly different by job/occupational variable in each of all body parts except the neck. The symptoms were very significantly different by task/activity variables in each of all body parts while those symptoms were significantly different by psychosocial variables, depending on body part and gender. In the logistic regression analyses performed for MSD symptoms by body part and each of 3 factors, odds ratio values varied, ranging from 0.7 to 3.3. The controls for reducing the symptoms were discussed on the basis of the findings. The results show that the MSD symptoms can remarkably vary by the factors and, in particular, can be highly differential for the task/activity factor. This study suggests that MSD symptom features be examined by using various factors and then a higher differential factor be primarily utilized for controling MSD symptoms in general industry including hospital settings.

The Purpose of this study was to identify of parent-child relationship, Perceived social support and coping of female in late adolescents and its relationships. The underlying assumption is that Parent-child relationship based on internal working cognition affects on perceived social support and coping. The sample was consisted of 277 female students of college. The instruments used in this study were Parental bonding instrument (PBI)(Parker, Tupling & Brown. 1979), Personal resources questionnaire : PRQ-part II (Weinert ' Brant, 1987), and Way of coping (Folkman & Lazarus, 1985). The data was analyzed using frequencies, correlation coefficient, ANOVA. and t-test. As a result. perceived social support correlated positively with Parental care and negatively with parental overprotection. Perceived social support showed positive relationship with coping. Perceived social support differed according to parent-child relationship type. The group of 'affectionate constraint' high care and high overprotection. reported high perceived social support, but 'affectionless control'(low care and high overprotection) reported low perceived social support. The group of high perceived social support showed higher parental care and higher coping than low one. The group of high coping showed higher parental care, lower parental overprotection and higher perceived social support than low one. Findings from this study linking retrospective accounts of early parental relationships to current working models concerning the nature of supportive relationships are consistent with attachment theory that individual who, as children, experienced relationships with their parents that were independent-encourage. affectionate, and not overprotective developed working models of others as available to provide social support. This study confirmed that perceived social support significantly related to coping in dealing with stress.

Objectives: This study was conducted to survey the related factors of metabolic syndrome of Chinese workers aged 20 years and above. Methods: The study was conducted at three locations in Shandong, China, currently working and took the physical examination (PE) within one year in the area as target participants. Personal characteristics, physical and biochemical results based on the PE, lifestyle habits, and food intake of the participants were used to analyze the relationship with metabolic syndrome. Results: Results showed that overall, thirty-one subjects (22.5%) had metabolic syndrome, twenty males (32.7%) and eleven females (14.2%). Metabolic syndrome was related to age, gender, educational level and occupational type with more risk in male (P < 0.05), people of older age (P < 0.001), low educational level (P < 0.05) and non-office workers (P < 0.01). According to the life style scores, lifestyle evaluation showed specifically alcohol consumption and smoking (P < 0.001) and stress management (P < 0.05) as important factors that were associated with the metabolic syndrome. High calorie (P < 0.01) and carbohydrate (P < 0.01) intakes were observed on male participants with metabolic syndrome in comparison to the non-metabolic syndrome but no significant difference on female participants. Conclusions: This results of this study can be used as significant supporting data to prevent and control metabolic syndrome in Chinese workers.

Purpose: This study was performed to examine motivational factors affecting sweetness preference in Korean and Japanese children. We identified meaningful variables that could be targeted to nutrition education interventions designed to overcome innate barriers and reduce sweetness preference and sweet food intake in Korean and Japanese children. Methods: Questionnaire surveys and sweetness preference test were conducted to examine variables affecting behavioral intention (BI) regarding sweetness preference. Questionnaire variables were based on the theory of planned behavior. Participants were recruited from one urban school from each country. In total, 166 children (mean age: 8.4 years) and their guardians (n = 166) participated in the study. A trained research assistant provided all children with personal guidance regarding completion of the sweetness preference test and survey questionnaire at school. The data were analyzed using Pearson's correlation coefficients, t tests, repeated measure ANOVA, and stepwise multiple regression analysis (significance level: p < 0.05). Results: Perceived behavioral control (PBC) and parenting practice were significantly associated with BI in both groups. Motivation to comply affected BI only in Japanese children, whereas affective attitude was associated with BI only in Korean children. In predicting sweetness preference, BI was associated only in Japanese children, whereas sweets consumption frequency had a significant effect in Korean children. Conclusion: The study shows similarities and differences in motivational factors, which could be considered when developing nutrition education programs in Korea and Japan. PBC and parenting practice were common factors in predicting BI. In predicting sweetness preference, BI had a significant effect on Japanese children, whereas sweets consumption frequency was the greatest contributor in Korean children.
