This study examines the influence of light variation on visual responses in a small office space where a daylight dimming control system is applied. Field measurements and survey were performed in a full-scale mocked-up small office space under clear sky day conditions. Maximum fluctuation range for desktop was 133.5 lx and it just happened once for entire monitoring period. For the majority of time, the fluctuation range did not exceed 50 lx, which did not cause visual discomfort to subjects. The daylight dimming control system successfully kept required illuminance levels for an office environment when desktop illuminance by daylight ranged up to 300 lx. The most serious contributor to the sensation of glare was direct daylight through window. The dimming of electric light was not a significant contributor to visual discomfort for the subjects under clear sky day conditions. Visual comfort was significantly influenced by the sensation of glare, feeling for visual stimulation and distraction, and required illuminance level.

웹이라는 환경은 다양한 정보원천을 생성해냈고, 온라인 소비자는 시간과 노력의 비용을 줄여 보다 합리적인 의사결정을 하기 위하여 웹 정보탐색을 한다. 특히 인터넷 환경은 정보를 획득하는 비용을 낮춤으로써 유용한 정보원천의 역할을 수행하고 있다(Bakos, 1997; Bar-Ilan, 2001). 그러나 너무 많은 정보는 오히려 소비자들의 의사결정을 방해할 수 있는데, 이때 소비자들은 정보원천에 대한 인지경향, 즉 신념수준을 가지고 자신에게 필요한 정보를 취사선택하게 된다(Schuman and Johnson, 1976). 이러한 관점에서 온라인상에서의 구매의사결정과 관련해서 주요하게 참조되는 정보원천을 파악하는 것은 의미있는 일이라 할 수 있다. 이에 본 연구에서는 사전조사를 통해 온라인 주요 정보원천으로 온라인 구매경험, 온라인 구전정보, 판매자 정보를 도출하였다. 그리고 이러한 정보원천이 제품만족, 정보만족에 미치는 영향관계를 알아보고, 이어서 정보만족과 제품만족이 인터넷 쇼핑몰에 대한 소비자의 전반적인 만족에 미치는 영향을 살펴보았다. 분석결과, 온라인 정보원천의 모든 변수들이 정보만족에 유의한 영향관계를 갖는 것으로 나타났으며, 제품만족과의 관계에서는 판매자 제공정보가 유의하지 않게 나타났다. 또한 정보만족과 제품만족 모두 소비자의 전반적인 만족에 유의한 영향을 미치는 것으로 나타났다. 이와 같은 결과는 온라인상에서의 정보의 중요성을 입증하는 것으로, 온라인 소비자의 정보원천에 대한 이용과 평가를 이해하는데 새로운 시각을 제공해주고, 정보원천에 대한 관리와 활용에 관한 실무적 시사점을 제시해 줄 것으로 기대된다.

본 연구는 미 L-A에 거주하는 한국이민 노인들의 특성을 파악하고, 그들의 생활만족도에 기여하는 결정요소들이 무엇인지 가려내며, 그 얻어진 결과를, 동일한 시각과 접근으로 시도되었던 미국 노인들에 대한 선행연구들의 결과와 비교 분석하였다. 연구는 1986년 12월에서 1987년 2월까지 3개월간 미 L-A 카운티에서 거주하는 55세 이상의 한국 이민노인 390명을 대상으로 설문지 조사를 실시하여 그중 192명을 자료분석에 사용하였다. 단계별 중다 회귀분석의 결과, 활동성의 제약정도, 결혼상태, 재정적인 안정, 교육정도, 연령증가 등 5가지 변인들의 특별히 한국노인의 생활만족도가 강한 연관성이 있었고, 반면 자신들이 평가한 건강상태, 지인과의 사회적인 상호작용, 미국거주 년한 등은 노후생활의 안녕에 전혀 직접적인 영향력을 행사하지 못했다. 그러나 자신들이 평가하는 건강상태는, 활동성의 제약 등과 같은 다른 변인에 미치는 효과를 통해서 생활만족도에 간접적으로 강하게 영향을 미치고 있었다. 이러한 결과를 선행연구에서 나타난 서구나 미국노인의 생활만족도 결정의 세 요인인 건강상태, 사회경제적 지위, 사회적 활동성과 비교해 볼때, 사회적 활동성과 연령증가 변인에서 서로 상반되는 대조를 보이고 있었다. 즉, 백인노인들은 나이가 듦에 따라 생활만족도가 낮아지거나 혹은, 연령증가와 생활만족도 사이에 별로 유의할 만한 관계를 보이지 않고 있으나, 본 연구에서의 한국노인은 나이를 먹으면서 오히려 생활만족도가 높은 것으로 나타났다. 한편, 사회적 활동성은, 백인노인의 생활만족도에 긍정적 혹을 부정적으로 가장 강하게 영향을 미치는 요인중 하나임에 반하여, 한국노인들은 이것이 자신들의 생활만족에 중요한 것이라 믿고는 있었지만 실제 통계학적으로는 영향력을 행사하지 못하는 요인이었다. 주거환경(자식과의 동거여부) 역시, 이제껏 한국사회에서 기대되어왔던 통념과는 달리, 한국노인의 생활만족도에 아무런 영향을 주지 못하고 있었다.

This study compared and validated consulting satisfaction analysis between consultants and participating companies in relation to consulting. The objective was to analyze the different perspectives on what consultants think of satisfaction and how businesses think of satisfaction to achieve the optimal improvements and to improve the quality of consulting. To explore ways to improve the quality and satisfaction of consulting, this study evaluated five service quality measures. After consulting, the research method aimed to determine what is required by the enterprise based on the SERVQUAL perspective, find key factors for how to address these requirements, establish evaluation criteria, and measure the satisfaction of consulting. The results revealed no statistically significant differences in the detailed measurement item type, reliability, responsiveness, reliability, and empathy for the quality of consulting by enterprises and consultants. Comparative analysis of the consulting satisfaction on the SERVQUAL items by companies and consultants showed that companies and consultants had different opinions to improve the consulting quality and satisfaction. Therefore, it would be important to narrow the differences on this and establish a structure, in which consultants and businesses cooperate with each other.

This paper introduces the improved and expanded contents of the previous research that implemented a system that guides the visually impaired using the vibration of a smart watch. In the previous study, we proposed an algorithm that recommends the most safe route based on calculating negative and positive values for the topography of the route and the features installed on the route. In addition, by designing several vibration patterns, a system that guides the user through vibration was proposed and implemented. In this paper, the user's personal preferences are reflected in the algorithm that recommends the safe route first. In addition, an automatic feedback function was added to the algorithm so that the user's satisfaction evaluation on the recommended route was immediately reflected. A history simulation function was added so that the past route could be reviewed, and the compass of a smart watch was used to help visually impaired people find directions at junctions.

NTIS(National Science & Technology Information Service) is the first national R&D information knowledge portal service in the world to provide information of government-funded R&D projects and it has been developed by KISTI. This study investigated several limitations of current NTIS information service, analyzed information needs for end users, and then proposed information recomposition and visualization method to satisfy their information needs. For doing this, we firstly clarified the definition of 'end-users' and classified three different groups of general users. We also discriminated various information needs according to three groups and illustrated some examples of visualization results to meet the requirements - 'retrieval simplification' and 'information visualization'. To consider practicality of our proposed method, we suggested implementation plans to utilize existed NTIS services.

To show the analytic approach to website sue, this paper discusses style's function that is immediately related to users emotional and aesthetic satisfaction. And we make an analysis of several websites based on various visual factors. Style provides emotion, a shared experience, context that makes the message arts function immediately apparent, and interests. It is a principle design feature that parallels cognitive function. Visual factors of website interface could be extracted from various aspects which are organization level, medial level, and formative level. Based on the extracted visual factors, we analyze the style which convey emotional idea. We select several sites which are opposite side in the image map with son-hard and warm-cool axis, and then make an analysis of them in two points which are organization and formative factors and communication means for emotional effect. To understand the systematic approach to website style could be helpful for figuring out the design problems and bringing out many solutions. It could be base for concrete guideline for website page design.

We propose a software-reliability growth model incoporating the amount of testing effort expended during the software testing phase. The time-dependent behavior of testing effort expenditures is described by a Weibull curve. Assuming that the error detection rate to the amount of testing effort spent during the testing phase is proportional to the current error content, a software-reliability growth model is formulated by a nonhomogeneous Poisson process. Using this model the method of data analysis for software reliability measurement is developed. After defining a software reliability, we discuss the relations between testing time and reliability and between duration following failure fixing and reliability are studied in this paper. The release time making the testing cost to be minimum is determined through studying the cost for each condition. Also, the release time is determined depending on the conditions of the specified reliability. The optimum release time is determined by simultaneously studying optimum release time issue that determines both the cost related time and the specified reliability related time.
