The issues for the aged have been appearing on the stage as the deep social problems since the end of 1970's when our communities began to enter into high level industry, which were concerned by people in modern times. The starting time to study on the aged in Korea was from the 1960's. Moreover, it was lively proceeded during the end of the 1970's and the 1980's. At first, it mainly dealt medical issues for them, then, spread up to their social concerns later. This study was to research about the participating type of the aged' leisure, sports activities, as well as its changable relationships with life satisfaction on the premise regarding the necessity of positive practice toward leisure and its participation as the positive solution scheme from the aged' issues, which was based on the social concerns related with the aged. According to the questionary method, to select the main group who were over 60-years-old, men and women in Pusan, it was studied and analyzed regarding the realities of the aged's leisure activities, the participating attitude in sports, the relationships between the degree of satisfaction life when participating in sports activities and the life satisfaction. The results were as follows ; 1. Among the low ranking scopes of the participating attitude in sports, in case of participating in sports for the self-training of character-building themselves, it significantly had and effect on the satisfaction of life. 2. In case of building their own character through sports activities, it had the highest effect on the satisfaction of life. 3. The satisfaction of sporting activities in their childhood had and effect on the life satisfaction.

The purpose of this study was to introduce item response theory(IRT) and to explore the possible applications to the measurement of psychomotor behavior. The primary assumption of IRT is an individual will respond to an item on a test can be described in terms of a probabilistic function that describes the probability of an examinee responding correctly to an item. By contrast with the classical test theory, the advantage of IRT is to be able to estimate examinee's true ability and the estimate does not depend on the other examinees or on the particular test administered. When the item response of an examinee is dichotomous, if the probability of an examinee responding correctly to an item would be dependent of the ability of the examinee and the difficulty of the item, Rasch Model or 1-parameter IRT model could be used for estimating the item parameters. But if the discriminant or guess factor would be considered, then 2-parameter of 3-parameter model could be used. However, when the item response is polytomous, polytomous response model such as Partial Credit Model, Rating Scale Model, Nominal Response Model can be used. Especially, Binomial Trial Model, Poisson Counts Model, and Inverse Binomial Model can be used for analyzing multiple-attempt, single-item skill tests of psychomotor domain. Through reviewing the literatures of IRT, item bank, computer adaptive testing, mastery test measurement of change, repeating skill test, and sequential test has been proposed as the possible applications for psychomotor domain. In conclusion, for more valid and reliable assessment in the pychomotor domain, IRT and the possible applications of IRT should be seriously considered in measurement research in physical education.

This study seeks to analyze and examine factors which affect and leisure leader's organizational behavior. The data for this study were collected at nine sports and leisure training institutes in Busan. At these sites 890 questionaires were distributed to a random sample of sport and leisure leaders. Of these, 849 were used for this study. The results were as follows. 1. Generally all background variables(sex, accupation, age, working conditions and experience of turnover) were related to work-related variables. Education, however, was not so related. Among background variables and organization-related variables, age, marital status and experience of turnover were related to level of pay, organizational commitment and institutional security. 2. The greater the satisfaction with job, working conditions and position, the less the turnover. In the organization-related variables, all variables (level of pay, coworker relations, organizational commitment and institutional security level) had a significant impact on turnover. 3. Work-related variables, organization-related variables, and nonwork- related variables had an impact on turnover intent in all sport categories: taekwondo (42.08%), swimming (32.09%), body-building (30.79%), bowling (29.96%) and golf (27.18%). Also, these variables displayed a significant impact on turnover attempt in all sports categories, except for taekwondo.

The corrosion resistance of Ti-Zr-Pd-Cr alloys were investigated in order to reveal their possible use for new biomedical implant materials. Titanium alloys consisting of 10∼20%Zr, 0.0∼0.4%Pd and 0.15%Cr were prepared by vacuum arc-melting as alloying elements instead of using hardness Al and V in response to recent concerns about the long term safety of Ti-6%Al-4%V ELI alloys. The Ti-Zr-Pd-Cr alloys were heat-treated at 1000℃ for 2hrs under a vacuum atmosphere. The effect of Zr and Pd Ti alloys on the corrosion resistance for biomedical implant was investigating the anodic polarization curve at 37℃ in 5%HCI solution deaerated by high-purity N₂gas bubbling. The critical current density for passivation(I ) of Ti-Zr-Pd-Cr alloys didn't reveal markedly. Passive current density(I ) at 1.0V vs. SCE of this alloys decreased with increasing Zr in the contents from 10 to 20% and decreased with containing Pd in the range from 0.2 to 0.4%. Potential(E ) at 0.1A * m-² of this alloys increased with increasing Zr in the contents from 10 to 20% and increased with containing Pd in the range from 0.2 to 0.4%. For the Co-30%Cr-6%Mo alloy, passivity zone is narrow, and rapid increase of current density result from the low potential in comparison with Ti and Ti alloys. The corrosion resistance by the anodic polarization of Ti-20%Zr-0.2%Pd-0.15%Cr alloy was found to be superior to those of the Ti, Ti-6%Al-4%V alloy and Co-30%Cr-6%Mo alloy. The passive films formed on the Ti-20%Zr-0.2%Pd-0.15%Cr and Ti-6%Al-4%V alloys in the anodic polarization test consist mainly of TiO₂, Ti compound, ZrO₂, Al₂O₃and V₂O₃.

This paper proposes multidimensional indexing techniques for nested attributes in object- oriented databases. We use a multidimensional dynamic file organization for these indexing techniques. Since most conventional indexing techniques for object-oriented databases use a one-dimensional index structure such as the B+-tree, they do not often handle complex queries involving both nested attributes and class hierarchies. We extend a tunable two-dimensional class hierarchy indexing technique for nested attributes in object-oriented databases. The tunable two-dimensional class hierarchy index is an indexing scheme that deals with the problem of clustering objects in a two-dimensional domain space that consists of a key attribute domain and a class identified domain for a simple attribute in a class hierarchy. In our extended scheme, we construct indexes using multidimensional file organizations that include one class identifier domain per class hierarchy on a path expression that defines the indexed nested attribute. This scheme supports efficiently queries that involve search conditions on the nested attribute represented by an extended path expression. An extended path expression is a one in which a class hierarchy can be substituted by an individual class or a subclass hierarchy in the class hierarchy.

최근 흡연을 시작한 젊은 성언에서 급성 호산구성 폐렴의 발생에 대한 증례가 보고되고 있다. 급성 호산구성 폐렴은 대개 발열을 동반하기 때문에 초기에는 감염성 폐렴으로 잘못 진단, 치료되는 경우가 많다. 아직 정확한 병태 생리 및 조직학적 소견은 밝혀져 있지 않지만 병력 청취 및 임상 양상, 방사선 소견의 관찰을 통해 급성 호산구성 폐렴을 의심하고, 진단을 위해 기관지 폐포 세척액 검사를 시행한다면 좀 더 쉽게 진단 내릴 수 있을 것이다. 본 저자들은 최근 처음 시작한 흡연에 의해 발생한 급성 호산구성 폐렴을 진단하고, 스테로이드를 투여하여 성공적으로 치료한 환자 2예를 경험하였기에 이를 문헌 고찰과 함께 보고하는 바이다. Acute eosinophilic pneumonia(AEP) is characterized by acute febrile respiratory illness associated with diffuse pulmonary infiltration and pulmonary eosinophilia. The specific etiology for acute eosinophilic pneumonia is elusive. By some investigators, cigarette smoking is suggested as a causative substance which can cause AEP. In recent, the authors experienced two cases of AEP following cigarette smoking. Both cases had characteristic features including age around 20 years, new onset smoking before occurance of AEP, diffuse infiltration on chest radiography, pulmonary eosinophilia based on bronchoalveolar lavage and acute improvement after steroid therapy. These clinical features are resemble with previous smoking induced AEP case reports. Base on these clinical features, cigarette smoking associated AEP could be diagnosed more easily.
