This study was attempted to explore meaning in life and it's relationship to problematic life events, health status and depression among older people. 198samples of elderly were over the age 60 (mean age=70.06) conveniently selected in Seoul, Korea. The data were collected through questionaires by interview with subjects from April, 1, 1999 to May 30, 1999. The research instuments were the main framework in the experiment. They involved meaning fulfillment and problematic life events which were developed by Burbank (1988) and short form geriatric depression scale(Sheikh & Yesavage, 1986). The data were analysed by SAS Program. The results are followed; 1. 172 lists were given out and had objects that would bring meaning to one's life. They were categrized as wishing for offsprings' prosperity, their relation with their grand-children, marriage of their offspring, health of family members, strong family ties, caring for the family, relation with husband, health for self, religious activity, helping others, individual hobbies, needs for growth such as writing, education, relationships with friends and personal achievements. In the end, 50% of total list dealt with in the relationship with their family members. 2. The mean fulfillment of the subjects was 38.31(SD=13.58) with a range of 12-60. The degree fulfillment varied according to the subjects' characteristics such as age group(F=4.44, 0P=.0008), education status (F=6.44, P=.0001), economic status (F=10.27, P=.0001), marrital status (F=9.12, P=.0002) and religious background (F=3.68, P=.006). 3. According to the pearson correlation, analysis significant variables were found between meaning fulfillment and health(r=.47, P=.0001), depression and the number of problematic life events for a life time (r=.147, P=.04), the stress score of problamatic life events for the past one year and the stress score of problematic life events for a life time was r=.43, P=.002, meaning fulfillment and the stress score of problamatic life events r=-.26, P=.04, depression and meaning fulfillment r=-.70, P=.0001 and depression and health r=-.521, P=.0001. 4. According to multiful regression analysis, depression was found as a most predictable variable for health(F=12.51, P=.001).

본 논문에서는 영화의 흥행을 예측하기 위한 방법을 제안한다. 최근 영화시장이 성장함에 따라 시장의 수요를 예측하기 위한 다양한 연구들이 수행되고 있다. 영화는 비교적 수명주기가 짧은 문화상품이다. 따라서 안정적인 수익을 창출하기 위해 개봉 전 마케팅비용 및 개봉 후 스크린 수 등에 대한 설계가 필요하다. 이를 위해서는 상품의 수요와 경제적인 수익규모에 대한 계산이 선행되어야 한다. 기존 관련 연구들의 경우 예측을 위한 변수로서 주로 영화 자체의 속성들이나 시장에서의 경쟁요인 등을 이용한다. 그러나 정작 상품을 구매하는 주체인 잠재관객들에 대한 비중은 비교적 미비하다. 따라서 본 논문에서는 사람들이 가진 영화에 대한 인지도를 고려하기 위해 트위터를 하나의 설문표본으로서 활용했다. 기존에 사용된 변수들과 트위터에서 추출한 정보를 오프라인 요소와 온라인 요소로 정의하고, 두 요소를 취합하여 기계학습을 적용했다. 실험을 통해 본 논문에서 제시하는 예측기법을 검증했으며, 실험결과 약 95%의 정확도로 영화의 흥행을 예측했다.

본 연구는 대표치가 아니라 임금분포 자체를 분석대상으로 하여 그것을 고용구조적 견지에서 다양한 기술통계적 방법과 반모수적 계량분석 방법을 활용하여 분석하였다. 한국 제조업의 대표적 임금분포는 형태상 상당한 차이를 가지는 후진형, 중진형, 그리고 선진형 분포로 구별된다. 분포 형태의 차이는 그것을 구성하는 노동유형 분포와 가중치의 차이로 규정되고, 노동유형 분포를 사용한 다양한 기술통계적 분석을 통해서 유형 차이의 발생 이유가 명백히 된다. 그러나 기술통계 분석은 개별 속성변수들의 영향이 혼재된 복합적 결과라는 한계점을 가진다. 이 문제는 비례적 해저드함수를 활용한 반모수적 추정, 그리고 변수 변화의 한계효과를 함수 차원이 아니라 추정된 함수가 가져오는 분포 차원에서 평가하는 방법으로 해결된다. 한계분석의 결과로서 후진형, 중진형, 그리고 선진형 분포에 영향을 미치는 속성변수의 공통적 특징과 차이점, 그리고 영향의 강도가 밝혀진다.

Poultry products including meat and eggs constitute a major protein source in the American diet and disease-causing pathogens represent major challenges to the poultry industry. More than 95% of pathogens enter the host through the mucosal surfaces of the respiratory, digestive and reproductive tracts and over the past few decades, the two main mechanisms used to control diseases have been the use of vaccines and antibiotics. However, in the poultry industry, there are mounting concerns over the ability of current vaccines to adequately protect against emerging hyper-virulent strains of pathogens and a lack of suitable, cost effective adjuvants. Thorough investigation of the immunogenetic responses involved in host-pathogen interactions will lead to the development of new and effective strategies for improving poultry health, food safety and the economic viability of the US poultry industry. In this paper, I describe the development of immunogenomic and proteomic tools to fundamentally determine and characterize the immunological mechanisms of the avian host to economically significant mucosal pathogens such as Eimeria. Recent completion of poultry genome sequencing and the development of several tissue-specific cDNA libraries in chickens are facilitating the rapid application of functional immunogenomics in the poultry disease research. Furthermore, research involving functional genomics, immunology and bioinformatics is providing novel insights into the processes of disease and immunity to microbial pathogens at mucosal surfaces. In this presentation, a new strategy of global gene expression using avian macrophage (AMM) to characterize the multiple pathways related to the variable immune responses of the host to Eimeria is described. This functional immunogenomics approach will increase current understanding of how mucosal immunity to infectious agents operates, and how it may be enhanced to enable the rational development of new and effective strategies against coccidiosis and other mucosal pathogens.

The blasting has a lot of economic efficiency and speediness but it can damage to a neighbor structure, a domestic animal and a cultured fish due to the blasting vibration, then the public grievance is increased. Therefore, we need to manage the blasting vibration efficiently. The prediction of the correct vibration velocity is not easy because there are lots of different kinds of the scale of blasting vibration and it has a number of a variable effect. So we figure the optimum line through the least-squares regression by using the vibration data measured in hard rock blasting and compared with the design vibration prediction equation. As a result, we confirm that the vibration estimated in this paper is bigger than the design vibration prediction equation in the same charge and distance. If there is a Gaussian normal distribution data on the left-right side of the least squares regression, then we can estimate the vibration prediction equation on reliability 50%(${\beta}=0$), 90%(${\beta}=1.28$), 95%(${\beta}=1.64$). 99.9%(${\beta}=3.09$). As a result, it appears to be suitable that the reliability is 99% at the transverse component, the reliability 95% is at the vertical component, the reliability 90% is at the longitudinal component and the reliability is 95% at the peak vector sum component.

Objectives: This study was conducted in order to determine how the association between socioeconomic position(SEP) and health status changes with age among Seoul residents aged 25 and over. Methods: We utilized the 2001 and 2005 Seoul Citizens Health Indicators Surveys. We used self-rated 'poor' health status as an outcome variable, and family income as an indicator of SEP. In order to characterize the differential effects of socioeconomic position on health by age, we conducted separate multivariate analyses by 10-year age groups, controlling for sociodemographic covariates. In order to assess the relative health inequality across socioeconomic groups, we estimated the Relative Index of Inequality (RII). Results: The risk of 'poor health' is significantly high in low family income groups, and this increased risk is seen at all ages. However, the magnitude of relative socioeconomic inequality in health, as measured by the odds ratio and RII, is not identical across age groups. The difference in health across income groups is small in early adulthood (ages 25-34), but increases with age until relatively late in life (ages 35-64). It then decreases among the elderly population (ages more than 65). When the RII reported in 2005 is compared to that reported in 2001, RII can be seen to have increased across all ages, with the exception of individuals aged 25-34. Conclusions: The magnitude of health inequality is the greatest during mid- to late adulthood (ages 45-64). In addition, health inequalities have worsened between 2001 and 2005 across all age groups after economic crisis.

The purpose of this research is to study the need for living and the relationship between the need and the perceived family well-being among families in rural areas and to suggest the index of the family well-being for them. One hundred fifty homemakers in the six rural areas in Chunlabuk-do were sampled for this research and all of them were aged under 60. Data were statistically analized by using statistical softwere package 'Statgraphics' and null jhyposeses were statistically tested at p<.10. From the results of this study, rural homemakers reported, generally, higher levels of the need for the various aspects of family living compared to those of the perceived levels of the family well-being. The need, the satisfaction and the dissatisfaction levels of the various aspects of family oiving were affected more frequently by living area, average monthly income, and the period of living whitin the same area. The satisfaction with the family well-being and living in rural area were affected more powerfully by subvariables related to the family financial living than by any other variables. The need for economic environment, the satisfaction with perceived level of assets, and income were major representative variables for the family finances. In case of the family interpersonal living, the need and the satisfaction with relationship between spouses and the family structure were more powerful varibales than any other variables. The relationship betweenparents and children was more powerful variable for the perceived family well-being than any other variables related to the family interpersonal living. Sampled homemakers thought that the satisfaction with relationship between spouses was the most important in family interpersonal living. The needs for household equipment and living conditions was positively influenced on the need of household work and the satisfaction with those was negatively influnced on satisfaction with present household work.
