Abstract- In a plasma source ion implantation, the target is successively biased by negative voltage pulses with an intrinsic finite rise time, resulting in the time-dependent sheath formation around the target. Measurement of time-dependent sheath during the pulse rise show the ion matrix sheath development which is in proportion to square root of time and pulse rise rate over plasma density but independent of the ion mass.

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.

Objectives : This study aims to estimate the prevalence of the DSM-IV psychiatric disorders in Korean population using the Korean version of Composite International Diagnostic Interview (K-CIDI). Methods : Subjects were selected by taking multi-stage, cluster samples of 7,867 adult household residents, 18 to 64 years of age, in ten catchment areas. Total 78 trained interviewers administered the K-CIDI to the selected respondents, from June 1 to November30,2001. Results : Total 6,275 respondents completed the interview. Some 33.5% of respondents reported at least one lifetime disorder, 20.6% reported at least one-year disorder, and 16.7% reported at least one-month disorder. The most common lifetime disorders were alcohol abuse/dependence (17.24%), nicotine dependence/withdrawal (11.19%), specific phobia (5.16%), and major de-pressive disorder (4.25%). The lifetime prevalence of substance abuse/dependence (0.25%) and schizophrenia (0.16%) was very low. Nicotine and alcohol use disorder showed very high male/female ratio. Mood disorder and anxiety disorder were more prevalent among female than male. Conclusion : The prevalence of psychiatric disorders was high. In comparison with other studies, remarkable differences in distributions of psychiatric disorders across the areas and times were observed.

Local government area plays a significant role in the administration of the state or local self-government and it also has a logical significance as an area where its inhabitants manage their daily life and maintain mutual ties. This implies that local administrative region is closely related to the efficient performance of administrative functions and maintenance of regional unity to cope with the complicated changes of modern society. The boundary of local self-government may not be considered separately from its functions, because regional limits within which such functions are performed varies according to the nature and substance of established functions of local self-government. The regional limits should also be properly adjusted according to the change of administrative functions of local self-government. On the other hand, the local administrative region has provided its inhabitants with a sphere of collective life for a long period of time and therefore it is deeply connected with their sentiment and spiritual ties. The change of region to meet new administrative demand without considering such regional factors will cause entrangement physically and spiritually between the inhabitants and local self-government, thereby lowering administrative efficiency. The boundary of local self-government is also deeply related not only to the efficient performance of state or local administration, but to the participation of the inhabitants in administration and administrative control as manifested by the idea of democratic politics. In other words, local administration should take into account the participation of the inhabitants and easy satisfaction of the principle of autonomy. From this point of view, the issue of local administrative region should be dealt with in the direction of its proper readjustment with mutual harmonization between the variables of regionalism and localism (local centralization of administration) among those for the enhancement of state and local administrative efficiency, maintenance of regional unity and administrative democratization. In the actual determination of proper scale of an administrative region, the manipulative definition and measurement of all variables involved should of course be preceded. It is intended in the present paper to analyze the problems of major foreign countries and investigate those involved in the local self-governing region of our country, thereby establishing the criteria of administrative region and designing the direction of its improvement.

A low density microcellular foam was prepared using inverse emulsion polymerization method. First radically polymerizable styrene monomer and water with nonionic surfactants formed inverse emulsion, then this system was polymerized. The microcellular foam was obtained by removing water phase. The morphology of emulsion foams with system variables was examined in terms of pore size, cell structure, bulk density, and specific surface area. The emulsion system variables including monomer feeding methods, oil phase/water phase ratio, surfactant/water ratio, and mechanical stirring conditions were consider in this study. The ratio of surfactant/styrene rather than that of styrene/water shows dominant effect on the pore size of emulsion foams. While the open-cell/closed-cell morphology was mainly determined by the ratio of styrene/water. Mechanical stirring also has an effect on the pore size. Sorbitan monooleate among various nonionic surfactants seems to be the best surface active agent in styrene/water inverse emulsion system.

Recently, lots of studies for high flowing concrete have been suggested under practical use that it is only a way to solve the confronted problem. However, most studies have been concentrated on the manufacture method and properties of fresh concrete, but there is few studies for the durability of hardened concrete, specially for the freezing and thawing. It is generally known that the frost resistance of concrete is much affected by the air content in concrete and by the air void system. The frost resistance is also believed to vary with the strength of concrete. The purpose of this experimental study is to make a comparison between high flowing concrete using viscosity agent and ordinary concrete about the effect of the viscosity agent, air content and curing method on the frost resistance. As the result of tutus study, the frost resistance have not effect the viscosity agent but effect the different of curing methods.

This study prepared a questionnaire for the measurement of dancers' anxiety about dance performance, based on a similar questionnaire of sports competition anxiety developed by Smith et al.(1990). The questionnaire as prepared here contained question items for the measurement of dancers' anxiety, worry and distraction. The question items were applied to survey respectively 70, 50 and 62 dance students at colleges in Busan over three sessions. The validity of the questionnaire was verified through the exploratory factor analysis and by using Cronbach αcoefficient. Cronbach αcoefficients for the questionnaire developed in this study were found ,7650 for 'distraction', .6480 for 'anxiety' and .6305 for 'worry', suggesting that the questionnaire was reliable in measuring dancers' anxiety about dance performance. Data from th survey as above mentioned showed that dancers were different with each other in such anxiety according to their cognitive and physical senses of dance stage and performance. The data also showed that such psychological aspect of dancers was influenced by their dance experience, dance career and personality, a performance place, stage settings, the tempo of performance music and stage costumes. There were no differences among dancers in anxiety according to their dancer career. In other words, dance career itself had nothing to do with dancers' confidence in performance. Despite they obtain high skills of dance expression by repeating dance practice, dancers tend not to be able to use such skills to the utmost in actual performance due to stresses and strains under a changed situation. This may be referred to as control confusion by personal, psychological anxiety rather than as lack in technical dance skills. It may also be regarded as a psychological state of stage fright(state anxiety in dance performance) dancers face when they do not practice dance in a closed space but meet the audience on actual dance stages. In relation, it was reported that dancers with high trait anxiety were higher in stage anxiety scores during dance practice and during and after dance performance than those with low trait anxiety. Meanwhile, it was suggested that a form of the psychological test of dancers considering characteristic of stage performance should be developed and that cognitive concepts of dance be actively studied. In conclusion, dance performance should be made only after dance practice which ensures harmony between physical and psychological aspects. Now the researcher would survey dancers by using a questionnaire for the measurement of dance performance anxiety, whose validity is clearly verified, and modify and supplement the questionnaire to raise its reliability. The the researcher would conduct a more profound study about effects of such anxiety as mentioned above on dance performance.

Background: Pneumocystis carinii (PC) is a opportunistic pathogen causing serious pneumonia (Pneumocystis carinii pneumonia : PCP) in immunosuppressed patients including AIDS. Laboratory diagnosis of PCP is dependent on microscopic demonstration of the PC by using cytochemical staining or by immunocytochemical staining with monoclonal antibodies. However, these staining methods are not highly sensitive. The development of the polymerase chain reaction (PCR) has made it possible to detect very small numbers of pathogens in clinical specimens. To establish the usefulness of PCR for detection of PC DNA, We performed PCR as a pilot study. Methods: PCP was induced on Spraque-Dawley rats with prednisolone 5mg IM twice a week. Bronchial lavages, impression smears, and permanent sections were performed from the 3rd week to 7th week of cortisonized rats. PC DNA was extracted with bead beater / 10% CTAB method. Results: Impression smears showed PC cyst after the 4th week (100%, 28/28 rats), and permanent sections showed 27/28 rats. Control rats showed some PC cysts (2/7). PCR result was positive only one case among the 6th week rats (1/7), But positive 6 cases at the 7th week rats, (6/7). Among control rats. 2 cases were positive (2/7). ??This data is a pilot study for the PC DNA detection using a PCR. PCP were successfully cortisonized rats. If adequate bronchial washing technique will be used, PCR can be a sensitive for PC DNA detection.
