This study examines the information exploration characteristic and relative importance evaluation of island tourism web site. The survey items are developed based on the related studies and also implemented particular way so-called 'semi-online' that including both web based material and offline tutorial. The first objective of this study is verifying the characteristics of information exploration on island tourism of university students. The second is examining the peculiar properties of tourism information that exposed one's individual importance evaluation. The result of this study shows that most of the students have no difficulty in using the internet and exploring the island tourism information. And there is no significant difference in using and exploring the internet between male and female students. Based on the result of this study, most popular type of island tourism information is picture type. Personal blog or user created contents(UCC) that containing the other's experience of island tourism is mostly wanted contents. But there is a significant difference in importance of contents within the students. The community based information which including UCC, blog, and other community user's posting is evaluated the most important information for relatively less experienced students. On the other hand more experienced students have a preference on expertise information which created by tourism experts. The difference within the determinant factors that affecting island tourism also significant. With analysis of variance(ANOVA) on determinant factors, the tourism activity and social/culture resource are less important than others(eg. natural environment, accommodation and so on). The result of this study would be practically used for implementing the local government's effective tourism web site and enhancing the current island tourism operation. And also it gives a advantage to facilitate the island tourism for young generations.

The purpose of this study is to offer information about the current river conditions and basic data of streams in Busan city, by selecting 20 underground streams and evaluating their multilateral stream assessment. Concerning the evaluation of streams, 4 sections including the general index, the bank index, the river characteristic index, and the ecological environment characteristic index were evaluated. Ahead of the evaluation, the study divided Busan city into 4 zone for a systematic river investigation. Then, the study allocated code names to each river, and conducted literature research and a field survey of streams. Based on this, the study applied the evaluation of multilateral stream assessment. As a result, out of 4 entire grades, there was no grade 1 or grade 2. Instead, 35% were grade 3, 60% were grade 4, and 5% were grade 5. When looking into the evaluation results by Zone, the Dongbusan Zone showed the highest index, and the Suyeonggang Zone, the Jungbusan Zone, and the Nakdonggang Zone followed, in order.

Recently, research on evaluating thermal comfort by using CFD has been vigorously active. This research evaluates not only distribution of temperature and air flow analysing but also thermal comfort in indoor space by applying human model. But research of human model's shape, Grid characteristic and turbulence model has not yet been studied. In this paper, human model's shape, physical characteristic of variable Grid, and change of turbulence model has been studies by CFD. In this study. FLUENT is used for analysis and PMV(predicted Mean Vote), PPD(Predicted Percentage Dissatisfied) and EHT(Equivalent Homogeneous Temperature} are used for evaluation and comparison of thermal comfort. As a result, it shows that shape of CSP and lattice features does not affect on global flow field or evaluation on PMV, PPD. However, it demonstrates more precise result from evaluation of thermal comfort by equivalent temperature when it used detailed human model considering prism grid.

게임 소프트웨어는 국내외적으로 상당히 인기가 높아지면서 시장 가치가 높아지고 있다. 그러므로 게임 소프트웨어의 평가 모델을 연구하는 것은 상당히 중요하다. 소프트웨어 품질 평가의 대표적인 국제 표준 모델은 ISO/IEC 9126이라고 보여진다. 특히 게임 소프트웨어는 사용자와 개발자에 있어서 소프트웨어 품질이 상당히 중요하므로 국제 표준 모델을 준수한 평가 모델이 필요하다. 이 연구에서는 게임 소프트웨어의 품질을 객관적이고 정량적으로 평가하기 위해서 소프트웨어 품질평가 메트릭을 제시하였다. ISO/IEC 9126의 소프트웨어 품질 평가 국제 표준 문서를 기반으로 기능성, 신뢰성, 사용성, 효율성, 이식성, 유지보수성의 6가지 품질 특성이란 관점에서 게임 소프트웨어의 품질 평가 모델을 제시했다.

200 N급 기체메탄/액체산소 소형로켓엔진의 성능시험평가 수행되었다. 산화제 공급압이 증가함에 따라 연소압과 추력이 증가하였으며, 이에 따라 비추력과 특성속도 및 그 효율이 증가하였다. 특성속도는 약 90%의 성능효율로 측정되었다. 시험조건의 연소실 종횡비 변화는 추력성능에 영향을 미치지 않았다. 또한, 시험결과의 신뢰도 확보를 위하여 불확도평가를 수행하였다.

In order to increase visitors' viewing satisfaction and viewing behavior in the art museum exhibit by flat works, it is necessary to analyze the characteristics of major evaluation factors, such as 'the number of artworks and their intervals', 'the space of exhibition and the size of walls', and 'compositional change of exhibition spaces', which have a close relationship with each evaluation factors, by focusing on artworks and exhibition space. Thus, to investigate how the characteristic differences of the major evaluation factors in art museums affect visitors' viewing satisfaction and viewing behavior, this study compared the related analytical indicators, and conducted a correlation analysis. The results of this study are summarized as follows: First, the degree of concentration on artworks (which has been selected as a collective assessment indicator of visitors' satisfaction) increased when the exhibition space of art museum is display by less artworks and they have big interval in the large wall. Second, visitors' viewing satisfaction and qualitative viewing behavior increased when the exhibition space of art museum are simple and they change to simpler step by step. These findings imply that there is a high correlation between visitors' visio-perceptual experiences and viewing behavior, and that visitors' viewing satisfaction and viewing behavior can be predicted partially in the certain exhibition environment from this correlation.

In this paper, software activity, software activity instance, and the quality of the activity instance are defined as the 'activity which is performed on the software product by a person or a group of persons,' the 'distinctive and individual performance of software activity,' and the 'performer's evaluation on how good or bad his/her own activity instance is,' respectively. The representative values of the instance quality population associated with a product and its sub-population are defined as the (software) activity quality and activity quality characteristic of the product, respectively. The activity quality model in this paper classifies activity quality characteristics according to the classification hierarchy of software activity by the goal. In the model, a quality characteristic can have two types of sub-characteristics : Special sub-characteristic and component sub-characteristic, where the former is its super-characteristic too simultaneously and the latter is not its super-characteristic but a part of its super-characteristic. The activity quality model is parsimonious, coherent, and easy to understand and use. The activity quality model can serve as a corner stone on which a software quality body of knowledge, which constituted with a set of models parsimonious, coherent, and easy to understand and use and the theories explaining the cause-and-relationships among the models, can be built. The body of knowledge can be called the (grand) activity-centric quality model of software.
