The grouping analysis is a method guided by the Korea Radioactive Waste Agency for efficient analysis of radioactive waste for disposal. In this study, experiments to verify the adequacy of grouping analysis were conducted with radioactive soil, concrete, and dry active waste in similar environments. First, analysis results of the major radionuclide concentrations in individual waste samples were reviewed to evaluate whether wastes from similar environments correspond to a single waste stream. As a result, the soil and concrete waste were identified as a single waste stream because the distribution range of radionuclide concentrations was "within a factor of 10", the range that meet the criterion of the U.S. Nuclear Regulatory Commission for a single waste stream. On the other hand, the dry active waste was judged to correspond to distinct waste streams. Second, after analyzing the composite samples prepared by grouping the individual samples, the population means of the values of "composite sample analysis results/individual sample analysis results" were estimated at a 95% confidence level. The results showed that all evaluation values for soil and concrete waste were within the set reference values (0.1-10) when five-package and ten-package grouping analyses were conducted, verifying the adequacy of the grouping analysis.

This paper develops a portfolio management game applicable to Korean Stock Market with an emphasis on teaching and training aid. It allows each participant to start out with a certain amount of money and pick his favorable stocks from a list of stocks chosen by instructor. Each participant must make a transaction at each time period and he gets a readout that states his individual performance, i.e., stock lists, cash on hand, net worth, transactions he has made and rank in accordance with his net worth. This game package consists of 10 subprograms and 7 files written with Fortran language for use on the Nova 840 computer and is divided into 3 main categories according to their functions, i.e., book-keeping function, data processing function and information searching function. This package may be used for training portfolio decison makings in the stock market and for comparing various investment methods through hypothetical investments.

본 연구는 다양한 관계에서 위축되고 의사소통이나 표현의 어려움을 갖고 있는 해체 다문화가족 아동들을 대상으로, 이들의 자아존중감 향상을 위한 지시적 개별모래상자놀이 프로그램을 개발하고, 그 효과성을 살펴보는 데 목적이 있다. 양적분석 데이터 수집을 위해 지시적 개별모래상자놀이를 통한 프로그램 사전 사후에 점수를 비교하였고, 수집된 자료의 통계처리로 SPSS 18.0 Package 프로그램을 사용하였다. 질적 분석을 위해 회기 내 B아동의 언어적 변화를 자기표현척도에 위해 수집하고 분석하였다. 연구기간은 2017년 2월부터 5월까지 약 3개월간 총 12회기 개별 활동과 1회의 집단 활동, 1박2일의 가족캠프 활동으로 총 6명의 아동을 대상으로 단일집단 사전사후 설계의 방법을 활용하였으며, 본 연구의 주요결과는 양적으로 지시적 개별모래상자놀이 프로그램을 통해 사회적 자아존중감 능력에서 z=-2,200으로서 p<.05보다 수준에서 유의미한 차이를 보였고, 질적으로 아동 B의 회기별 언어적 표현이 회기가 진행될수록 긍정적 표현이 증가하고, 부정적 표현은 감소하는 것으로 나타났다. 이는 무엇보다도 주제를 제시하는 지시적 개별 모래 상자의 접근방법과 더불어 가장 안정적 환경인 아동의 집으로 방문하는 과정이 해체 다문화가족 아동의 자아존중감 향상을 증가시키는 효과성을 보이는 것을 의미한다. 본 프로그램을 바탕으로 하여 다양한 내담자 특성에 따라 지시적 접근방법을 통한 이동형 개별적 모래상자 프로그램으로 가는 전초적인 기본 틀이 마련 될 것이다.

The purpose of this study was to investigate social support buffering stress symptoms and the relationship between stress symptoms and job performance. The data were obtained from questionnaires completed by 529 workers employed in textile or clothing companies. The SPSS package was used for data analysis which included t-test, ANOVA, and correlation analysis. The results showed there were significant differences in the perceived levels of social support according to individual differences such as gender, marital status, length of service, title of current position, and division of responsibility. Workers with a high level of supervisor or co-worker social support were found to have the lower levels of stress symptoms. Social support appeared to moderate the relationship between stress symptoms and job performance.

This study is to measure and evaluate the sensibility image for textile pattern design based on the generation. Ten patterns classified by a practical survey on the market are presented. A questionnaire has 14 sensibility related words scaled by 7 point semantic differential method. The practical research is performed for 200 women screened by sensibility test for individual character analysis based on the generation. Each subject is answered by a face-to-face interview method to improve survey's accuracy, For statistical test about differences in treatment means, SAS package is used and analyzed through ANOVA, significance probability and mean, In summary, this paper has proposed the sensibility image scale for apparel pattern design to satisfy individual sensibility, The results of this study can be effectively applied to develop textile pattern design based on human sensibility.

This study investigated the use of participatory design kit as a tool for the design of individual units within an apartment tools through the literatures. Simulation was the method used for conducting the study. The results show that: 1) In general, design tools must be composed of a package of techniques, demand flexibility in its framework which adapts to a variety of situation, and the approach for project work must be comprehensive and systematic. 2) Design kits that are created to involve future residents in making decisions about the layout of their apartments, Improve the ability of those people to make various design. 3) Specifically, design kits that are developed as a means for making the user participation easy in an apartment housing complex, show the tool useful to an nonexpert.

The water content, physical property and sensory of cigarette brands lave been studied from the view point of the individual and inner packages. It was found that the cigarettes had absorbed the moisture from alto more than 56% of a relative humidity (RH) and lost it under RH, 56%. The critical moisture contents for the optimum quality of cigarette maintenance were 7.7% through 14.595 in the range of equilibrium relative humidity (ERH) 52.2%-63.5%. The ERH at the initial moisture content of 12.1% showed 58.8% When cigarettes were storaged in 9095 of RH and 4$0^{\circ}C$, the shelf life of the Inner package was respectively shown 18.8 days In cellophane, 33.3 days In PET(25u), 69.8 days in OPP and 73.5 days in OPP film coated with PVDC. As shown above, the longest life time was found in the OPP film coated with PVDC. In the individual packages, the shelf life of packaging materials used above was significantly short in the same conditions as of the inner packages. Each shelf life of the individual packages was same In order comparing with that of the inner Packages.
