The purpose of this research was to investigate the relationships between the socioeconomic condition, health attitude and the eye health of the elderly. Thereupon, this study is attributed to promote the eye health of the elderly. Data were collected through questionnaire by one-to-one interview in a community. The content of original questionnaires were revised by literature review and the pilot study. The sample was consisted of 285 elderly with a mean age of 71.8 years. In the study group, female was 52.3% and male was 47.7%, respectively. In age group, over 80 years was 16.5%, 75-79 was 21.0%, 70-74 was 29.5%, 65-69 was 26.0% and 60-64 was 7.0%. In maritai status, married and living with spouse was 54.4%, widowed was 45.6%. The elderly were suffering with diseases of arthritis(33.3%), hypertension(20.1%), cataract(14.2%) and diabetes(9.7%), respectively. Socioeconomics conditions were measured with monthly allowance money : The upper group those who can spend over 310,000 won was 13.6%, 110,000-300,000 won was 34.0%, less than 100,000 won was 52.5%, respectively. Therefore, the person who were very active health practice group were correlated positively with the wealthier group. Of the total, 33.2% of the elderly answered, they are suffering from two kinds of diseases combined at the same time. For the elderly who have the more concem on eye health were positively correlated with the higher educational level, live with spouse, and the ones who can spend the more monthly allowances. Eye health concem is positively correlated to health attitude.

VSS X 관리도는 이상원인에 의한 공정의 변동이 작은 경우에 통계적으로나 경제적으로 효과적인 관리도이다. 본 연구에서는 두 가지 이상원인이 공정의 평균에 복합적으로 영향을 끼치는 경우 VSS X 관리도의 최적 샘플 크기 결정을 위한 경제적 모형을 제시한다.

Systems are often operated by not integration but blocking, i.e., non-standardization. The system blocking is mainly caused by non-standardization or incompatibility. The integrated system is effective, but researches for quantification of effectiveness from integrating system are few. System blocking causes additional cost which is almost intangible and potential. In this paper we proposed a model to quantify the effectiveness of system integration. To verify the validity of proposed model, we applied the model for Korean information and communication industry and forecasted the cost of integration for South and North Korean telecommunication industry in the way of three scenarios.

Under the sudden change of competitive environment, the economic cooperation as a part of survival strategy is being a big issue among countries. There was much discussion based on the geological adjacency as well as cultural homogeneity regarding the eco

유류오염 사고를 사전에 예방할 수 있는 정책 수단으로는 여러 가지가 있지만 주요한 것으로는 인센티브제의 활용을 들 수 있다. 유류오염 사고를 예방하고 관리하기 위한 인센티브는 유출 사고로 인해 발생한 해양자원의 피해에 대해 가해자에게 배상책임(liability for losses due to spills)을 부과함으로써 제공될 수 있다. 유류오염 사고로 인한 피해액을 실제 화폐단위로 계량화하는 작업은 배상책임 부과제도를 정책수단으로 활용하기 위해 해결해

우리나라의 국민표준체위조사는 1979년 1차 조사를 시작으로 약 5∼6년 주기로 실시되고 있으며, 1997년 제4차 조사가 실시되었다. 국민표준체위조사 결과를 기반으로 한 인체측정치는 의류, 신발, 가구 등 관련산업의 제품설계에 반영되었다. 본 논문에서는 국민표준체위조사 결과자료를 기본으로 성별, 연령별, 체형별로 사용자를 분류한 후 체형별 분류를 위한 인체측정치를 도출하였다 도출된 인체측정치의 상관관계를 분석, 대표적인 항목 도출 등의 과정을 통하여 3D 캐릭터를 구성하였다. 구성을 위한 과정으로 골프, 테니스 등의 스포츠 동작을 효율적으로 나타낼 수 있는 인체 측정치를 도출하였다. 항목이 결정되면 각 타입의 3D 캐릭터를 구성할 수 있는 치수를 제시하여 생성하였다. 스포츠의 자세 및 동작분석에 대한 이론적 접근에서 가시적인 정보제공 및 자세ㆍ동작분석 프로토콜을 개발함으로써 자세 및 동작에 대한 정량적ㆍ객관적 평가가 가능해졌다.
