Purpose. This study was conducted to provide basic data for decrease campus life stress investigated survey on the socio-demographic characteristic and campus life stress of the dental hygiene students. Methods. The research subjects are the total 220 and it was analyzed with structured questionnaires. The collected data was analyzed by IBM SPSS ver. 20.0, a statistical program (IBM Co., Armonk, NY, USA) for the frequency and percentage, ANOVA, Regression. The result is as following Results. The campus life stress was statistically significant differences by in case of poor family reason (${\beta}$=0.287), the fourth grader(${\beta}$=0.151), pocket money a month(${\beta}$=-0.136). Conclusions. As the results of the reasearch, it is necessary support and expansion plan with systemized cooperation between the government and school to state scholarship, living expenses and worker's scholarship for decrease the campus life stress.

The ultimate purpose of this study is to suggest the most effective marketing strategy for the clothing consumer market based on the new generation consumer's clothing selection behavior analysis. In this thesis, it is appempted to make a progress in the new gen-eration consumer's clothing life style types, in clothing purchase behavior analysis among the clothing life style, and also in the marketing strategy for marketers. The subjects selected for the final analysis are 412 the new gerneration women of age 20 thru 34 in seoul and satellite town area. Data were processed the spss package program. As for the analytic method, factor analysis, clustering analysis, XCross-tubulation, F-test with ANOVA, frequency and percentage were applied in the survey. The major findings are as following : life style is classified into four types : The characteristic fashion-directory type(25.7%) ; The reason traditional type(9.0%) ; The sen-sitivity fashion-following type(11.0%) ; The community brand-conscious type(54.3%). 2 Clothing life style types characteristic of the new generation consumer proved that clothing life style types are a significant difference according to the life style, the fashion consciousness and the average monthly spend-ing on clothing. 3. There is an important discrimination according to the clothing life style types in their clothing purchase behavior such as infor-mation usage, clothing choice criterion and brand loyalty. 4. Based on the result of our analysis and the review of literature, the marketing strategy is suggested that characteristic and new design development is efficient way to consumer's purchase need. Therefore apparel industary which pursue an added value must frame marketing strategy on the basis of the target consumer's sensitivity characteristic according to the life style and fashion consciousness.

The fatigue characteristic of a material or a structure is derived from fatigue tests of standard specimens. However test results of standard specimens are very different from those of real structures or components. Therefore, to calculate more accurate fatigue life, the geometrical effect and surface condition must be considered by comparing test results of standard specimens with those of real structures or components. Thus the object of this paper is to evaluate the fatigue characteristic of a real waterwork pipe by conducting fatigue tests with standard specimens and non-standard(plate-shaped) specimens of base metal and weld metal. Also, to evaluate fatigue characteristic based on life distribution, statistical fatigue characteristic was analyzed by the normal distribution and related data of P-S-N curve.

Purpose. This study was conducted for provide basic data to improve satisfaction of campus life that investigated survey on the socio-demographic characteristic and campus life stisfaction of the dental hygiene students in Gyeongnam and Busan region. Methods. The research subjects are the total 220 and it was analyzed with structured questionnaires. The collected data was analyzed by IBM SPSS ver. 20.0, a statistical program (IBM Co., Armonk, NY, USA) for the frequency and percentage, ANOVA, Hierachical regression. The result is as following. Results. It was investigated to affected campus life satisfaction by in case of female student(${\beta}=-0.232$), in case of employment preparation(${\beta}=-0.193$), in case of household economical poor status(${\beta}=-0.188$). Conclusions. As the results of the research, it is considered necessary the expansion of the systemized, in order to increase the campus life satisfaction, improvement to the university administration and welfare for the emotion of girl, development program for interview skill and smooth interpersonal relationship, support major costs and living expenses.

Practically, induction surface hardening is used widely to enhance the local strength of structure. In this study, Fatigue limit and its S-T characteristic for raw and induction hardened specimen of SCM440 is studied experimentally. The life prediction was considered by Juvinall's equation and its predicted result is compared with experiment.

The purpose of this study was to comprehend specific characteristic of interface and present the standardized interface of Long Life Housing, which could be obtained by the total and various approaches. With this in mind we analyzed related studies of interface through previous studies, and based on the analysis we created standardized factors of categorization in view of characteristic of interface. Using these factors, we can determine whether the interface could be used systematically in Long Life Housing. And as these were presented in the form of Key Map for expedite the synthetic understanding of interface, we could easily reconize types of interface. Especially, we only dealt the wall of flexible interface of Long Life Housing. Throughout systemizing and standardizing works, we can expedite the understanding of interface of Long Life Housing and finally, we want to make basic data used for date base of interface which can be available for Long Life Housing.

In order to establish preventive maintenance standards through analysis & reliability prediction of about 60,000pcs of 20kindsof relays and contractors used for Seoul subway trains, several life prediction methodologies were applied. Firstly, Occurrence, Severity, Detection were defined and predicted by applying operation characteristic of EMU to the number of actions of relays & contactors which the manufacturers generally offer as the life cycle data. Secondly, failure distribution and average life of parts were analyzed through interpretation of field data based on a lot of experience which had built up in the field for a long time. Finally, using the 217PLUS standard as a reliability prediction program, comparative analysis of use reliability and inherent reliability was done through reliability prediction at the part level and system level.

The shelf-life of pharmaceutical products is the time that the average product characteristic remains within an approved specification after manufacture. Since the true shelf-life of a drug product is typically unknown, it has to be estimated based on assay results of the drug characteristic from a stability study usually conducted during the process of drug development. The nonparametric statistical methods of assessing the shelf-life of drug are considered with the current FDA regulations. Some simulation studies of nonparametric methods are also presented with the discussion.
