  • This study conducted an analysis of the correlations among menopausal symptoms of middle-aged women, their exercise performance and subjective health conditions on those 417 middle-aged women aged 40-59 years, residing in Seoul and the Kyongki Province area, from December 6, 2000 through Jun. 20, 2001, using the SPSS 10.00 program. Resultant findings were revealed, as follows: 1. A difference was represented in general characteristics between menopausal symptoms of middled-aged women and variables such as satisfaction with life, sexual life, diseases, the presence or absence of surgical operations; a difference between exercise performance and variables such as age, the presence or absence of vocations, weight control, satisfaction with life, and sleep; and also a difference between subjective health conditions and variables such as weight control, satisfaction with life, diseases, and the presence or absence of surgical operations. 2. Furthermore, a difference was revealed between the levels of menopausal symptoms by exercise performance and variables such as mental and physical symptoms and psychological symptoms. 3. The group of good exercise performance showed higher subjective health conditions as to subjective health conditions by the levels of exercise performance. 4. The better their subjective health conditions, the lower their menopausal symptoms as to menopausal symptoms by subjective health conditions. 5. A negative relationship was disclosed between menopausal symptoms and exercise performance; a positive relationship between exercise performance and subjective health conditions; and a negative relationship between subjective health conditions and menopausal symptoms.

  • A new product development is critical to the growth and success of most business firms. Increasingly, the new product development is recognized as an essential component of the corporate plan. But, relatively few research investigations have focused on the elements of a new product development strategy and its performance results. This study aims to identify the patterns of new product development strategy which business firms adopt, and its performance results. To identify these patterns and results, 268 firms in four industries known to be active in new product development were selected as a matter of convenience, and surveyed by the questionnaire and interviews. The questionnaire is composed of 67 strategy variables, 8 performance variables, and other variables. To analyze the data from samples, various statistical methods such as factor analysis, Pearson correlation analysis, sluster analysis, and one-way ANOVA were employed. This analysis brought forth the following major findings: First, three new product development strategy patterns were identified. Each strategy pattern was proved to be different from the others in terms of group of strategy elements that were adopted. Second, the new product development strategy was closely linked to its performance. Third, the difference of performance results among strategy groups in each industries was rather significant, however, the performance difference among industries in each strategy group was less significant.

  • In a large number of literature on of inspection tasks, one of the most consistent findings is the existence of large and consistent differences among inspectors. It is possible that the individual difference is described by the difference of cognitive skills, because cognitive skills are required more than manual skills in inspection tasks. Therefore, a set of cognitive factors in human information processing may underly human performance in inspection tasks. In this study, a cognitive skill was described as the relative importance of the cognitive factors involved. A hierarchical task analysis and a fuzzy hierarchical analysis were used to represent how the importance of cognitive factors contribute to inspection performance. An experiment was conducted using the computer simulations of PCB inspection tasks. The results revealed that the subject group with better performance showed the importance weights of cognitive factors in the following rank; (attention, perception, judgement, classification, recognition)<(detection)$\ll$(memory). The results of the experiment can serve as a selection criterion for efficient inspection performance and the information of skilled learning for an inspection training program. The usefullness of a hierarchical task analysis and a fuzzy hierarchical task analysis for the analysis of cognitive tasks are also confirmed.

  • Social capitals are getting more important for management in enterprises, especially in small and medium sized enterprises(SMEs). The purpose of this study is to examine the effect of social capitals on the performance of intellectual property. For the empirical analysis, survey data were collected from 138 companies in one industry cluster, 34 companies in the other one. The data were compared using regression analysis. The findings confirm a positive influence of the conceptive social capital on the performance of intellectual property while there are no effect of structural and relational social capitals on the performance. These are different from the past researches. In addition, there is no difference between industrial types such as IT, BT, and NT in terms of the effect of social capitals on the performance of intellectual property. Also there is no difference between the two industry clusters.

  • Recently, a MEMS gyroscope has been broadly fabricated and used due to development of a micromachining. However, there is a difference between the modeling design and the actual product and this difference can lead to the performance variation of a MEMS gyroscope. A classical design method does not exactly estimate the performance of a MEMS gyroscope. Therefore a design process considering the design variable uncertainty has to be employed to design MEMS gyroscope model. In this paper, the equation of motion of a MEMS gyroscope model is obtained to analyze the performance of a MEMS gyroscope and the effects of the design variables on the MEMS gyroscope performance are investigated. Finally the performance of MEMS gyroscope is estimated through a statistical analysis based on sample statistics.

  • 해양온도차발전용 유기랭킨사이클은 해양의 표층수와 심층수사이의 온도차를 이용하여 발전하는 사이클이다. 작동유체는 유기랭킨사이클의 열역학적 성능에 있어 중요한 요소이다. 유기랭킨사이클의 열역학적 분석방법으로 핀치포인트분석이 있다. 본 연구는 열교환기내 핀치포인트온도차의 변화와 열원 및 열침의 출구온도의 변화에 따른 열역학적 성능분석을 수행하였다. 핀치포인트분석법에 따라 설계한 해양온도차발전용 단순랭킨사이클에 7종의 단일 작동유체를 적용하여 열역학적 성능을 분석하였다. 성능분석결과 열교환기에서 핀치포인트온도차와 열원 및 열침의 온도변화가 작을수록 사이클 총 비가역성 및 총 엑서지 파괴인자가 감소하였으며, 제2법칙 효율은 상승하였다. 또한 비가역성은 열역학적 변화가 발생한 곳에서 크게 변화하였다. RE245fa2는 선정한 작동유체 중에서 가장 우수한 열역학적 성능을 보여주었으며, 모든 작동유체의 성능은 유사하였다. 열교환기 및 작동유체 선정에 있어 열역학적 성능과 함께 다양한 요소들에 대해서도 엄밀한 이론적 근거가 필요하다.

  • The purpose of this study was to gauge customers' satisfaction with the hospital, university, factory, and office foodservices from a contracted provider. Importance-performance analysis (IPA) evaluations were conducted. Questionnaires were returned from 1,808 customers in 46 foodservice locations. The average total scores of the importance and performance of seventeen quality characteristics were 4.14 and 3.23, respectively, on 5-point scales. The average total score of gap (gap = performance - importance) was -0.92. Analysis of significant difference according to the type of foodservices revealed that, hospital foodservices had more items with significant high scores than those of other groups in the average total scores concerning importance (p<0.01) and performance (p<0.01). The average total scores of gap showed no significant difference. Significant differences were evident in the food and personal service dimensions, and the scores of hospital foodservices trended significantly higher than those of other groups. Importance-performance analysis (IPA) analyses for hospital foodservice implicate 'variety of menu', 'cleanness of dishes', and 'taste of food' as items requiring prompt attention and improvement.
