  • 대학의 게임개발 프로젝트에서 QA를 수행하기 위해 필요한 테스트 베이시스를 확보하기 쉽지 않다는 문제가 있다. 이렇게 테스트 베이시스가 부족한 경우 경험기반 테스트 기법이 대안이 될 수 있다. 탐색적 테스팅은 경험기반 테스트 기법 중에서도 체계화가 되어 있는 기법이다. 본 논문에서는 탐색적 테스팅을 활용할 경우에 필요한 탐색적 테스팅 수행 절차와 보고서 양식을 제시하였다. 본 논문에서 제안하는 QA 프로세스와 양식은 실제 게임개발 프로젝트에서 유용하게 적용할 수 있다.

  • Search strategies is a means to make an efficient search. Among several studies of search strategy, Bates' $\ulcorner$Search Tactics$\lrcorner$ has been often cited and introduced, but their studies have been superficial. In this paper, the contents of Bates' $\ulcorner$Search Tactics$\lrcorner$ are examined in detail, and we try to represent the actual online search process based upon Bates' $\ulcorner$Search Tactics$\lrcorner$. The following three kinds of survey are made in order to clarify which and how tactics are used: (1) Interview with 7 searchers who belong to different types of organizations, and use different kinds of databases (2) Analysis of some online search records. (3) Analysis of written applications for a newspaper database during one year. In conclusion, Bates' tactics falls into categories and new several tactics which often used are added. The following five factors affect online search activities, search strategy, and search tactics. (1) the difficulty of search requests (2) the kinds of databases (3) the charging policy for each online search (4) the presence of the user during the search (5) the searcher' online experience In the limited condition, typical tactics are suggested, but in order to generalize the pattern of using tactics, further investigation is necessary.

  • It is widely known that the dynamic optimal path algorithm, adopting real-time path finding, can be supporting an optimal route with which users are satisfied economically and accurately. However, this system has to search optimal routes frequently for updating them. The proposed concept of optimizing search area lets it reach heuristic optimal path rapidly and efficiently. Since optimal path should be increased in proportion to an distance between origin and destination, tremendous calculating time and highly efficient computers are required for searching long distance journey. In this paper, as a result of which the concepts of partial solution and representative path are suggested. It was possible to find an optimal route by decreasing a half area in comparison with the previous method. Furthermore, as the size of the searching area is uniform, comparatively low efficient computer is required for long distance trip.

  • This study examines the relationships between export intensity and knowledge search activities of Korea SME manufacturers. Using 2,145 firm data from the 2011 SME Technology Statistics Survey, we focused on the nonlinear relationships of export intensity and internal and external knowledge search activities. The results show that there are U-shaped relationships between export intensity and both of internal and external knowledge search activities. Local market-oriented or global market-oriented SMEs than the middle-level of exporters have more search activities both internally and externally. This study extends our understandings on the relationships between export intensity and knowledge search activities. There are some policy implications to develop supporting programs differing in knowledge search activities according to the acceleration of export or globalization of Korean SME manufacturers.

  • Consumer innovativeness is a force that leads to innovative behavior of consumer and it is crucial for companies to understand the innovativeness in association with the new innovative product adoption. The purpose of this paper is to examines the influence of Consumer's inherent innovativeness, product involvement, and product expertise on consumers's vicarious and adoptive innovativeness. For this purpose, the model has been set and examined the influence of consumer innovativeness, product involvement and product expertise on vicarious and adoptive innovativeness. The results revealed that 1) consumer innovativeness would not influence vicarious and adoptive innovativeness, 2) vicarious innovativeness had affect on adoptive innovativeness 3) product involvement had a affect on both vicarious and adoptive innovativeness 4) product expertise had a affect on vicarious innovativeness and yet had no affect on adoptive innovativeness.

  • The purpose of this paper is to investigate the impact of internet shopping motivations on information searching intention, customer satisfaction and purchase intention. To achieve this goal, literature review and empirical studies were conducted in parallel. The results of this study are as follows: First, the motives of internet shopping of Chinese consumers were found to be in four dimensions, "seeking convenience," "seeking low-cost," "seeking variety" and "seeking pleasures", in order of large proportions, respectively. Second, Among these four internet shopping motivations "seeking convenience,""seeking variety" and "seeking pleasures" were found to have direct, significant and positive effects on information searching intention. But "seeking low-cost" has no positive effects on information searching intention. Third, information searching intention was found to have direct impact on customer satisfaction and purchase intention. Fourth, Customer satisfaction has an direct and positive effects on purchase intention.

  • 본 연구는 실내 환경의 경로탐색을 위한 실내녹화 효과의 적용 및 그로 인한 실내녹화의 환경 분석을 위해 수행되었다. 이 환경 분석은 실내공간 이용자들의 공간 인지의 어려움을 개선하고자 하는데 그 기초를 두고 있으며, 이 공간 인지의 불편함을 일으키는 인자인 환경적 설계 특징을 개선하고자 한다. 이러한 환경적 인자의 설정을 통해 실내 환경 개선 및 환경적 설계기준이 마련되어진다. 본 연구에는 4학년 학부생 57명이 선정되었고, Spielberger 상태 특성 불안 검사를 통해 불안정도가 높은 피험자와 불안정도가 낮은 피험자 두 그룹으로 범주화하였다. 실험 참여자들은 건물 실내 환경의 지정된 공간을 찾아가는 두개의 다른 경로탐색 환경을 인지하도록 하였다. 원래의 건물 실내 환경공간과 시뮬레이션 작업에 의한 실내녹화 공간이 설치된 새로운 건물 실내 환경공간의 두개의 경로탐색 환경이 본 실험에 이용되었다. 실험 참여자들은 실내녹화 공간이 설치된 경로탐색이 용이한 공간을 인지함으로써 the STAI, the Hospital Anxiety and Depression Scale, the Positive and Negative Affect Scale이 개선되었고, 불안정도가 낮은 피험자들이 불안정도가 높은 피험자에 비해 실내녹화 공간이 설치된 경로탐색이 용이한 공간을 좀더 적극적으로 인지하는 것으로 나타났다. 본 연구의 의의는 실내녹화 공간의 경로탐색 효과를 규명하고, 실내 환경의 미학적 환경계획을 시행하여 실내공간 이용자들의 미학적 관점 및 공간 인지를 높이는데 기여하였다는 점이다.

  • The main purpose of the research is to illustrate the value of the spatial statistical approach to residential differentiation by providing a framework for exploratory spatial data analysis (ESDA) using a local spatial separation measure. ESDA aims, by utilizing a variety of statistical and cartographic visualization techniques, at seeking to detect patterns, to formulate hypotheses, and to assess statistical models for spatial data. The research is driven by a realization that ESDA based on local statistics has a great potential for substantive research. The main results are as follows. First, a local spatial separation measure is correspondingly derived from its global counterpart. Second, a set of significance testing methods based on both total and conditional randomization assumptions is provided for the local measure. Third, two mapping techniques, a 'spatial separation scatterplot map' and a 'spatial separation anomaly map', are devised for ESDA utilizing the local measure and the related significance tests. Fourth, a case study of residential differentiation between the highly educated and the least educated in major Korean metropolitan cities shows that the proposed ESDA techniques are beneficial in identifying bivariate spatial clusters and spatial outliers.
