최근 시스템이 점차 대형화되고 복잡화되면서 시스템의 요구사항은 소프트웨어 프로젝트의 성패를 결정하는 중요한 문제로 인식되었다. 특히 소프트웨어 품질에 관심이 높아지면서 고품질의 소프트웨어 개발을 위해 노력이 활발히 이루어지고 있다. 이러한 노력의 일환으로 소프트웨어의 품질 속성을 나타내는 비기능 요구사항을 추출.분석을 위해 연구가 진행되고 있으나 극히 미진한 연구가 진행되고 있다. 본 논문은 이를 위해 소프트웨어 개발의 초기단계인 요구사항 단계에서 비기능 요구사항을 분석하고 이를 설계 단계에서 사용할 수 있도록 기술하는 방안을 제시한다.

The papaer reviews four theoretical acceptance sampling plans as OC(Operating Characteristics) curve based inspection, rectifying inspection, switching inspection, and continuous inspection. In addition, the study presents practical limitations of theoretical acceptance sampling by attribute and by variable. Finally, following research also recommends the sampling inspection based on production technology. However, the inspection method requires quality expertise with various experience and implicit knowledge of the field.

사회의 복잡화와 인터넷의 성장으로 인하여 매일 급속도로 증가하고 있는 정보들을 사용자가 모두 검토해 보고 자신의 기호에 맞는 정보들만 선택하여 사용하기는 어려운 일이다. 이를 보완하기 위해 자동화된 정보 여과 기술이 사용되는데 대표적인 방법으로 내용 기반 여과(information Filtering) 기술과 협력적 여과(Collaborative Filtering) 기술이 있다. 이 중 협력적 여과 기술은 정보의 속성을 고려하지 않는다는 단점을 가지는데 본 논문에서는 이를 보완하여 정보의 대표 속성을 중심으로 선호도 예측을 수행하는 개선된 협력적 여과 방법을 제안한다. 그리고 기존 협력적 여과 기술과 예측의 정확성에 대하여 성능 비교 실험을 수행함으로써 제안한 방법의 타당성을 제시한다.

Purpose: To obtain the area for improvement, the Importance-Performance analysis(IPA) uses relatively simple questions, that is, satisfaction and importance at attribute level. However, no attempt has been made to consider the gap between own company's performance and those of competitors in IPA, in the field of quality management. This study is aimed to suggest a new prioritizing method for improvement and to test for validity of the proposed technique. Methods: This study used data collected from Song and Lim(2015), which is satisfaction of employees, customers and competitors as well as importance data for 7 quality attributes of K animal hospital. A correlation comparison with other priority methods such as Bacon(2003)'s model and Matzler and Hinterhuber(1998)'s QI index is conducted. Results: The priority results by the proposed method shows better in correlation coefficient with customer perceived priority for improvement than other methods. Conclusion: From the result of the current study, it can be concluded that the result of the proposed method is valid, while it is relatively easy to understand and analyze, and therefore no additional survey is necessary for improvement priority.

This study identified the importance and performance perceptions of funeral foodservice service quality toward funeral foodservice employees, chief mourners/the bereaved and funeral visitors. Data were collected using self-administered questionnaires from 102 funeral foodservice employees, 71 chief mourners/the bereaved and 293 funeral visitors. According to the result of the survey, 'hygienic food production process' was recognized as the most important attribute while 'neat appearance of food' had the least performance. By comparing the importance of service quality attributes between three subject groups, it can be identified funeral foodservice employees had the highest recognition while funeral visitors had the lowest (p<0.001). Furthermore, funeral foodservice employees had a significantly high performance level compared to chief mourners/the bereaved in all 19 service quality attributes (p<0.001). The IPA result toward funeral foodservice employees indicated the following attributes that required improvements: 'reasonable menu price' and 'kindness of helpers'. Another IPA result from chief mourners/the bereaved recognized 'reasonable menu price' as a service priority. Overall, implications for funeral foodservice managers regarding service quality improvement are discussed.

Purpose: Marine transportation companies must improve service quality to secure competitive advantage and continuous relationships with customers. This study explores the value and necessity of service quality in the industry by empirically identifying the factor that would have the largest effect on the improvement of service quality, also examining whether such improvement may actually influence continuous relationships. Research design, data and methodology: Based on an online survey with those in the Korean marine transportation industry, this study conducted statistical analyses using structural equation modeling. Based on relevant previous studies, the current study constructed a total of 55 survey questions. Finally, 281 questionnaires were collected, but 68 were excluded owing to invalid responses. Results: Information service attribute had the largest effect on service quality, whereas communication did not demonstrate a significant influence. In addition, distribution and information services exerted a positive effect on service satisfaction through service quality, and finally influenced relationship continuity. Conclusions: The results shows that marine logistics service quality strategies which were centered on time or local factors, should be considered in terms of the development of innovative services. In particular the improvement of information service systems and strategies in changed business environment.

This study investigated the relationship between land cover and the water quality variables in the rivers, which are located in the Yamaguchi prefecture of West Japan. The study area included 12 catchments covering $5,809\;Km^2$. pH, dissolved oxygen, suspended solid, E. coli, total nitrogen and total phosphorus were considered as river water quality variables. Satellite data was applied to generate land cover map. For linking alterations in land cover (at whole catchment and buffer zone levels) and the river water quality variables, multiple regression modeling was applied. The results indicated that non-spatial attribute (%) of land cover types (at whole catchment level) consistently explained high amounts of variation in biological oxygen demand (72%), suspended solid (72%) and total nitrogen (87%). At buffer zone-scale, multiple regression models that were developed to represent the linkage between the alterations of land cover and the river water quality variables could also explain high level of total variations in suspended solid (86%) and total nitrogen (91%).

The purpose of this study is to analyze the characteristic of quality attributes of smart hotels by using a SERVQUAL-IPA model, focusing on Chinese, which has the most proactive approach for the adoption of smart hotel system. Toward this goal, six quality factors-tangibles, reliability, assurance, responsiveness, empathy, and playfulness-were extracted through factor analysis, and IPA was used to appraise the degree of importance and satisfaction for each quality attribute. As a result of the SERVQUAL-IPA model, quality attributes were categorized into four groups of 'keep up the good work,' 'possible overkill,' 'low priority,' and 'concentrate here.'. Furthermore, it was concluded that there is a need to focus on the following elements: 'smart devices can assist customers in emergency situations', 'when the room control system identifies customer needs, the staff can provide prompt service', 'development and improvement of mobile applications that enable customers to control room amenities', 'regular maintenance for smart devices', and 'providing data-driven personalized recommendations through customer activity data analysis'.
