Custom-tailored products are meant by the products having various sizes and shapes to meet the customer's different tastes or needs. Thus fabrication of custom-tailored products inherently involves inefficiency. To minimize this inefficiency, a new paradigm is proposed in this work. In this paradigm, different parts are grouped together according to their sizes and shapes. Then, representative shape of each group is derived and it will be used as the work-piece from which the parts in the group are machined. Once a new product is ordered, the optimal work-piece is selected through making similarity comparisons of new product and each representative shape. Then an effective NC tool-path is generated to machine only the different portions between the work-piece and the ordered product. The efficient machining conditions are also derived from this shape difference. By machining only the different portions between the work-piece and the ordered product, it saves time. Similarity comparison starts with the determination of the closest pose between two shapes in consideration. The closest pose is derived by comparing the ray distances while one shape is virtually rotated with respect to the other. Shape similarity value and overall similarity value calculated from ray distances are used for grouping. A prototype system based on the proposed methodology has been implemented and applied to the grouping and machining of the shoe lasts of various shapes and sizes.

본 연구는 정확한 중소기업 일자리 정보를 알지 못하는 상황, 선호 기준에 맞는 일자리 파악이 어려운 현실을 브랜드 범주화 이론을 반영한 '고용주 브랜드(Employer Brand)' 관점에서 개선하고자 하였다 이를 위해 청년구직자 700명을 대상으로 위계적 회귀분석을 통해 5가지 가치 요인(Interest Value, Social Value, Economic Value, Development Value and Application Value) 중심의 취업의향 영향요인을 파악하였다. 분석결과 청년구직자는 인재육성이나 제품, 서비스, 경영진 등 기업 측면의 특성보다 구직자 개인에게 직접적 영향을 미치는 업무문화와 환경, 자신의 전공 활용 등에 보다 관심을 가지고 취업의향에 영향을 받는다는 것을 확인하였다. 이는 중소기업 일자리 정책이 기존 양적 지원 중심에서 플랫폼 중심의 일자리 정보 활용을 강화하는 질적 체질 개선으로 변화될 필요가 있음을 시사하고 있다.

최근 건설공사에 있어서의 VALUE ENGINEERING 적용에 대한 관심이 높아지고 있으며 VE WORK-SHOP 을 통한 많은 효과가 현대건설의 사례에서 입증이 되고 있음에도 신문매체 등에 발표되는 VE 관련 논고가 일반론적 기고에 국한되어 있어 VE에 대한 이해에 큰 도움은 되지만 갈증을 해소하기에는 어려운 실정이며 우리사회에 전문성을 가진 리더군이 많지 않음을 반증하는 것도 되기에 향후 좀더 많은 VE 경험을 토대로 한 리더군이 형성되어 다양한 주제를 기사화한 실무적인 VE 기법의 소개가 필요하다고 본다. VE 적용은 그 기법이 매우 다양하므로 해당 공사의 시기와 특성, 제약요소 팀원 구성의 전문성 등 다양한 요소를 종합적으로 고려하여 가장 적합한 형태의 VE가 추진될 수 있도록 VE 계획 시 추진 팀의 방향설정과 역할분담이 필요하고 준비되어야 한다. 특히 WORK-SHOP 형태의 VE는 현장 테마 중임의 ITEM VE에 비하여 적은 투입으로 많은 효과를 거둘 수 있지만 팀원의 전문성이 결여시 VE 작업결과의 시행에 따른 신뢰도가 떨어질 수 있는 가능성을 내포하고 있으므로 추진팀의 입장에서는 보다 세심하고 조직적으로 접근 할 필요가 있다. 성공적인 VE 작업을 하기 위하여서는 특히 WORK-SHOP 개념의 새로운 기법을 설계 및 시공초기에 단계적으로 적용하고 VE 팀 리더의 효과적인 VE 작업을 위한 절차의 명확한 이해와 선진 기법의 이해를 바탕으로 한 팀원의 교육과 가이드가 점점 중요한 요소가 되고 있다. 실제 건설공사에 있어 효과적인 VE를 적용하기 위한 핵심요소를 VE 교육을 진행하고 있는 담당 실무자 입장에서 정리하여 보았으며 기회가 허락되면 한 두 차례의 추가 연재를 통하여 상세히 논하고자 한다.

The purpose of this study is to design effective working systems which adapt to change in human needs by developing an method which forms into optimal groups using the measure of cohesion. Two main results can be derived from the study as follows : First, the clustering method based on the entropic measure of cohesion is predominant with respect to any other methods proposed in designing the work groups, since this clustering criterion includes symmetrical relations of total work groups and the dissimilarity as well as the similarity relations of predicate value, the clustering method based on this criterion is suitable for designing the new work structure. Second, total work group is clustered as the workers who have the equal predicate value and then clustering results are produced through the combinatorial agglomerative hierarchical clustering method. This clustering method present more economic results than the method that clustering the total work group do.

The purpose of this study is to investigate the relations between housewife's self esteem and attitude toward household work its satisfaction and to find out how independent variables(housewife's age, education level, employment, household work helper, type of family) have effect on the two dependent variables. The measurement of self-esteem was based on the self-concept test standarized by Jung Won Sick, reformed the Fitts measurement for Korean Society. In order to measure of attitude toward household work and its satisfaction, based on the previous research, researcher made the measurement . the research was conducted on 234 housewives in Seoul in September 1984. Data was analyzed by percentage, mean, frequence analysis of variances, Pearson's correlation coefficient. The result can be summarized as following. 1)Over on half of housewives have high self-esteem comparatively. 2) Age and education level were variables to have influence n the attitude toward household work. 3)The attitude toward household work and its satisfaction comparatively were high. 4)Education level and type of family were variables to have influence on the attitude toward household work. Education level, employment and household work helper were variables to have influence on the satisfaction of house hold work. 5) Level of Self-esteem has influence on the attitude toward household work and its satisfaction. The higher level of self-esteem was, the higher becomes the score of the attitude toward house hold work and its satisfaction. Following suggestions can be extracted form the results of above study. 1) research of housewife's self-esteem didn't established a setted theory yet. I think, therefore, it requires deeper study about housewife's household work look upon as her occupation and relation between the household work as her occupation and her self-esteem in this area. 2) Population and sociological variables, used in this study, hardly influenced on self-esteem, the attitude toward household work and its satisfaction. Also the result didn't correspond with one another. So I think it requires need of further study how psychological and family function variables will have influence on housewife's self-esteem, the attitude toward household work and its satisfaction. 3) To recognized the value of household work objectively, many researchers tried to investigate of economical value of household work, But if housewife can realize her self-actualization through household work, it requires the study that try to objectively not only estimate the economic value of household work, but also the contribution of the aspect of family psychology.

Although telecommuting of SMEs has been activated due to the COVID-19 phenomenon, the security model for this is insufficient. Accordingly, the study was divided into threats centered on smartphones and threats centered on smartphone users. As a result of the study, one-third of SMEs are working from home. At this company with 100 employees, more than 50% of them work from home.and In the metal, machinery and chemical industries with factories, 20% of them work from home. As a result of analyzing the correlation between telecommuting according to the presence or absence of a factory, the correlation coefficient (r=-.385) has a clear linear relationship. And, as a result of the regression analysis, the R-squared value was 0.148, so companies with factories are highly related to telecommuting. In other words, we found that SMEs with factories do not want to work from home. In addition, as a result of analyzing the level of security threats, there were great concerns about theft, hacking, and phone taking during remote work. As limitations of the study, there were difficulties in selecting SMEs from the population in a non-face-to-face work environment, and there were limitations in the questionnaire items for deriving a non-face-to-face work environment.

Purpose: The purpose of this study is to investigate effects of shift work on married nurses' role conflict and job satisfaction. Method: Study subjects consisted of married nurses employed at four general hospitals with over 500 beds located in Seoul and Kyunggi area. The data were collected from March 15th to April 7th, 2004 using the survey and the subjects were asked to reply through self-administrative method. Results: Mean value of role conflict of nurses who worked shift work was measured 3.12 out of 5, and that of nurses who did not was measured 2.98. Mean value of job satisfaction of nurses who worked shift work was measured 2.79 out of 5, and that of nurses who did not was measured 2.86. There was a significant reverse correlation between mean level of role conflict and of job satisfaction. Both groups, nurses who worked shift work and nurses who did not, showed significant reverse-correlation in two areas. In the case of nurses who worked shift work, role conflict not showed a significant correlation. Job satisfaction showed a significant correlation with the plan to work as a nurse and remuneration in the case of nurses who worked shift work. Duty of supporting family was the factor affecting role conflict and measured 4.2% in the case of nurses who worked shift work, and the plan to work as a nurse and the academic background in the case of nurses who did not work shift work. Conclusion: To reduce role conflict and to improve the degree of job satisfaction, there should be taken a measure to improve a financial compensating system for working shift work for nurses who worked shift work, and to help nurses not working shift work to design plans for their job as nurses with stability.
