본 연구는 근린공원에 대한 이용자의 공원지각환경이 건강증진인식에 미치는 영향을 분석하기 위해 경상남도 창원시의 8개 근린공원을 대상으로 공원별 현장조사 및 설문조사를 실시하였다. 연구결과에 따르면, 먼저 공원별 공원지각환경에서는 대부분의 공원이 집에서 공원까지의 거리와 집에서 공원까지의 길 환경이 높게 평가된 반면, 수공간과 공원 내 다양한 볼거리는 충분하지 못한 것으로 분석되었다. 다음으로 23개의 지각환경 변수들을 요인분석한 결과, 경관성, 안락성, 접근성, 활동성, 편의성, 쾌적성의 6개 요인으로 분류되었다. 이를 토대로 건강증진인식과 지각환경요인과의 관련성을 분석한 결과, 8개 공원 중 4개 공원에서 지각환경요인이 신체적 건강증진인식에 유의한 영향을 주는 것으로 나타났다. 특히, 접근성과 활동성이 3개의 공원에서 영향력이 있는 변수로 분석되었다. 또한, 심리적 건강증진인식의 경우, 8개 공원 중 5개 공원에서 유의한 영향을 주는 것으로 나타났으며, 접근성이 4개의 공원에서 영향력이 있는 변수로 평가되었다. 이상과 같은 결과들은 기존의 공원 환경을 개선하고, 새로운 공원을 조성하고자 할 때 효율적인 기초자료로 활용될 수 있을 것으로 판단된다.

Recently, CMM have been recognized as a critical factor to validate the competitiveness of software organizations, even if the organizations have already achieved the ISO9001 certification. Furthermore, the new version of ISO9001:2000 is being required instead of ISO9001:1994. Both CMM and ISO9001 have a common point that they pursuit quality improvement for the organizations processes and products. Therefore, it is important to understand the similarities of specific requirements between the two models in software organizations which attempt to employ both of the models. From this background, this paper compares CMM and ISO9001 by considering the versions in 1994 and 2000 of ISO9001. The results of this research are likely to help software organizations ma]fe a decision for a strategy to adopt CMM and ISO9001.

Purpose: A main aims to classify quality attributes for quality assurance activities of military supplies by company size, and to derive the necessity for business improvement by company size to improve customer satisfaction through customer satisfaction coeffiecient and PCSI Index. Methods: Through a survey of defense and general businesses located in Busan and South Gyeongsang Province, the quality of service elements are classified and the client satisfaction factor and PCSI is calculated for the quality assurance activities. Results: Determine the current level of customer satisfaction with the quality of the Defence quality assurance service and present operational factors that need improvement by size of the company. Conclusion: The attractive quality of service factors for quality assurance work were in common and different and the need for improvement was identified based on differences in PCSI Index by Company size.

In heavy grinding that is on of the high efficient grinding method, meaningful deformation is generated by high temperature. So, after machining, geomeric error generated od the workpiece. The most important factor on the geometric error is temperature difference between upper layer and lower layer (T $_{d}$) . Relations between Td and grinding condition and maximum geometric error and grinding condition are obtained by experiment. This relations are used in fuzzy algorithm for improvement geometric accuracy. The main results are follows : (1) The linear relation between maximum geometric error and grinding condition is ovtained by experiment. (2) The linear relation between maximum temperature difference between upper layer and lower layer and grinding condition is ovtained by experiment. (3) Control peth of wheel for improvement geometric accuracy is obtained by using the fuzzy algorithm.m.

Power quality improvement in a three-phase four-wire system is achieved using a new topology of DSTATCOM (distribution static compensator) consisting of a star/delta transformer with a tertiary winding and a three-leg VSC (voltage source converter). This new topology of DSTATCOM is proposed for power factor correction or voltage regulation along with harmonic elimination, load balancing and neutral current compensation. A tertiary winding is introduced in each phase for a delta connected secondary in addition to the star-star windings and this delta connected winding is responsible for neutral current compensation. The dynamic performance of the proposed DSTATCOM system is demonstrated using MATLAB with its Simulink and Power System Blockset (PSB) toolboxes under varying loads. The capacitor supported DC bus of the DSTATCOM is regulated to the reference voltage under varying loads.

The improvement of perspectives on dark and limited underground space could be an important factor in successful underground space development. Current trend in the apartment underground parking lot requires not only quantitatively energy efficient design and operation, but also qualitative improvement of the space. For this, we need to consider two factors: Firstly, to understand the characteristics of the fluorescent lamp. Secondly, to improve the uniformity ratio of illuminance. In winter season, a way to keep the uniformity and a method not to lower the indoor illuminance level by cold ambient air. Therefore, a change in interval and arrangement of the lighting fixtures is required. Also, in their operation, current time-fixed control method needs to be changed into the control that method considers the use pattern.

This paper presents a derating design approach for reliability improvement of an aluminum electrolytic capacitor. The capacitor, usually mounted in a printed circuit board, is used to stabilize the circuit. The main failure mechanism of interest is dry-up of the electrolyte that is mainly caused by two stresses-temperature and voltage. The lifetime under these stresses is modeled as a function of these stresses and time using accelerated life testing. Quantitative variation in the lifetime, according to variations in these stresses, is investigated to perform the derating design of the capacitor so that the stress levels are selected to achieve required reliability measures for reliability improvement. Moreover, sensitivity analysis shows which stress would be a more important factor determining the lifetime.

The purpose of this study is to investigate the characteristics and suggest the Improvement directions of the facilities in Recreational Forests. This study adopted such various analysis methods as reviewing related documents, surveying the existing sites, and using questionnaire to visitors and managers. The result of this study can be summarized as follows ; 1) The major facilities of Recreational Forests are the lodging, recreation, and sports ones. 2) The primary factor for the visitor's satisfaction is the quality of natural environment, but that for their dissatisfaction is the lack of variety of the available facility. 3) The major problems of facilities in Recreational Forests are their number and design. This study suggests the improvement of accessibility and design of the facilities in the Recreational Forests.

In this study, a new model for improving the settlement environment and revitalizing hilly and mountainous areas was presented. A case study was conducted in two rural villages of Nakatsu-Mura in Wakayama-Prefecture, Japan. The settlement environment was evaluated from the point of view of the local residents, and the expectation of the local residents about the regional revitalization of their village in the future was assessed. From the analysis, each factor used far the assessment displayed characteristics of the two rural villages well. The type of improvement in rural villages was classified by a combination of the degree of satisfaction over the current settlement environment and expectation about the regional revitalization of the villages in the future. A method for improving and revitalizing settlement environments was clarified.
