  • 정보화 사회로 발전이 되면서 고품질 소프트웨어에 대한 관심과 요구가 증대되고 있다. 이에 따라 소프트웨어 제품 품질을 평가 및 관리하는 활동이 개발 활동과 함께 중요시되고 있다. 또한, 소프트웨어는 관련되는 이해당사자 마다 품질을 바라보는 다양한 시각이 존재할 수 있으며, 개발의 각 단계에서 중점적으로 관리되어야 할 품질특성이 필요하게 된다. 이러한 다양한 관점과 수명주기의 특성을 고려한 품질특성의 중요도는 품질관리 활동을 보다 효과적으로 수행할 수 있게 해준다. 그러나 소프트웨어 품질의 중요도에 대한 연구는 그 필요성과 효과성이 제대로 부각되지 않아 많은 연구가 진행되지 않았다. 본 논문에서는 소프트웨어 제품 품질의 기준이 되는 ISO/IEC 9126을 기반으로 소프트웨어 수명주기에서 품질특성의 중요도를 결정하는 기법을 제시하고자 한다. 제안된 기법은 소프트웨어와 관련되는 주요 이해당사자들을 대상으로 한 설문조사와 AHP 기법을 이용한 중요도 분석을 통해 이루어진다. 이를 통하여 수명주기에서 중요도 우선순위에 의하여 품질특성을 선별할 수 있으며, 소프트웨어 품질을 정량적으로 측정하고 개발 완료 후의 소프트웨어의 품질을 예상할 수 있게 하여 고품질의 소프트웨어를 획득할 수 있게 한다.

  • A prerequisite for improving the quality of a product is to enhance the quality of its parts supplied from outsourced enterprises. An enterprise certified by ISO 9001 Quality Management System is expected to develop their effective quality assurance system and maintain it through continuous control and improvement, thereby ensuring the good quality of products that they produce. However, it is reported that small and medium-sized enterprises certified by ISO 9001 have difficulty establishing an effective quality assurance system. This study aims to propose a new method of improving a quality assurance system that can be more effective in small and medium-sized enterprises. This study collectively considered requirements specified in several international standards on quality system and the results of expert group brainstorming to identify evaluation areas and items for assessing a quality assurance system. Based on these evaluation areas and items, a set of checklists for diagnosing and improving a quality assurance system was developed. In order to demonstrate the usefulness of the proposed method, this study applied it to ten small and medium-sized enterprises and could identify four approaches for improving their current quality assurance system. The presented improvement method, which consists of establishment of quality goals and quality innovation plan, defective products corrective activities, 4M and design change process, improvement of customer quality information management, is expected to be utilized as a useful tool for the enhancement of the quality assurance system of small and medium-sized enterprises.

  • Purpose: The purpose of this study is to suggest a key quality factor affecting user satisfaction based on quality attribute of weather information system and additionally, a managerial implication for activating weather information service market by analyzing causal relevance between weather information system and business performance. Methods: As its method, a causal relevance of quality factor of weather information system affecting satisfaction and business performance was analyzed by using structural equation model. An enterprise utilized in analysis sample performed a survey by targeting 186 distribution/logistics and general manufacturing company. Results: It was revealed that information, service quality of weather information system exerted a significant influence on user satisfaction and it did not take a significant influence on business performance in terms of quality of information, system and service. A significant relevance between user satisfaction and business performance was strong supported. Finally, it was revealed that utilization level of weather information system had a moderating effect on business performance. Conclusion: Domestic weather information system mainly focused on information utilization based weather information system and additional service level utilizing weather information is very low in practical terms. Therefore, in order to expand domestic weather related service market, systematic market expansion strategy of providing corporate customized service and case enlargement would be required.

  • Warranty cost usually involves complex factors paticularly when the product concerned consists of a great deal of parts. In spite of that it can be assessed by means of rather simple mathematical expression, it is possible to realistically appraise the sensitivity to any type of quality policy. This paper thus presents the mathematical concept related to the warranty cost and the general relationship showing that quality policy can be established in connection with the economic quality level.

  • 이 연구는 기계경비서비스품질이 기계경비고객만족이 고객충성도에 미치는 영향과 전환장벽이 고객충성도에 미치는 영향을 규명하는데 있으며, 조사대상자는 현재 C, S, N, T업체의 기계경비를 이용하고 있는 사업장의 업주들 560명을 대상으로 설문지를 배포하여 조사하였다. 본 연구에서 실증 분석된 연구가설의 결과를 요약하고 고객 전략적 측면에서 시사점을 제시하면 다음과 같다. 첫째, 성별에 따라 기계경비만족도가 대안의 매력에 미치는 영향과 인간관계가 고객충성도에 미치는 영향은 남, 여 간의 차이가 나타났으며, 이용기간 및 연령대에 따라 기계경비서비스품질만족도와 대안의 매력은 차이가 있는 것으로 나타났다. 둘째, 기계경비서비스품질만족도가 높을수록 기계경비고객만족도, 전환비용 및 인간관계에 정적(+)인 영향을 미치는 것으로 나타났다. 셋째, 기계경비고객만족도가 높을수록 전환비용, 인간관계 및 고객충성도에 정적(+)인 영향을 미치는 것으로 나타났다. 넷째, 전환비용이 고객충성도에 미치는 영향에서 전환비용이 높을수록 고객충성도에 정적(+)인 영향을 미치는 것으로 나타났으나, 인간관계 및 대안에 매력에는 유의한 관계가 없는 것으로 나타났다. 이상의 연구결과를 종합해 보면 기계경비이용자들이 기계경비서비스품질만족과 기계경비고객만족도에 대한 인식을 높게 하고 이러한 높은 인식이 전환장벽을 구축하여 높은 고객충성도를 높일 수 있다는 결론을 얻었다. 따라서 기존고객들에 대한 철저한 고객관리와 함께 기계경비서비스품질과 기계경비고객만족도, 전환비용에 대한 투자와 노력이 핵심전략임을 제시할 수 있다. 성공적인 경영을 위해서는 고차원적인 기계경비서비스 품질만족도와 장기고객에게 다양한 고객기반 강화프로그램을 마련하여 고객들에게 실질적인 가치와 편익을 제공함과 동시에 가격적으로 탄력적인 자세를 취하여 높은 전환비용을 마련하여 고객들이 차별화를 직접적으로 지각할 수 있는 각종 커뮤니케이션과 홍보채널을 마련한다면 충성도가 높은 고객집단을 개발하고 유지할 수 있을 것이다.

  • The goal of water quality management on stream and watershed is to focus not on discharged loads management but on a water quality management. Discharged loads management is not goal of water quality management but way for perform with total maximum daily loads management. It is necessary to estimate the relation between non-point source with stromwater runoff (NPSSR) and water quality to select a watershed where it is required to manage NPSSR for water quality improvement. To evaluate the effects of NPSSR on stream's water quality, we compare the aspects of water quality in dry and wet seasons using flow duration curve analysis based on flow rate variation data by actual surveying. In this study we attempt to quantify the variation characteristic of water quality and estimate the Inflow characteristic of pollution source with water quality and flow rate monitoring on 10 watersheds. We try to estimate water quality and flow rate by regression analysis and try again regression analysis with each high and low water quality data more than estimations. An analysis of relation between water quality and flow rate of 10 watersheds shows that the water quality of the Nonsan and the Ganggyeong streams had been polluted by NPSSR pollutants. Other eight streams were important point source more than NPSSR. It is wide variation range of $BOD_5$ also high average concentration of $BOD_5$. We have to quantify water quality variation by cv1 in wet season and cv365 in dry season with comparing the estimate of high water quality and low water quality. This method can be used to indicator for water quality variation according to flow rate.
