In this paper, we analyzed that a performing director can make effective advertising and publicity with any medium during the overall performance planning. We discovered 3 steps which are before viewing(viewing motive), during view(service quality) and after viewing(content quality) which affect purchase decision on viewing performance followed by an adjustment effect according to media type. Through surveying and analyzing the results, we confirmed that viewing motive, service quality, and content quality have significant effect on purchase decision and significant adjustment effect according to media type. Therefore, we expect that a performing director can make an effective advertising and publicity decision with any medium during performance planning.

Recently, increasing attacks using network packets cause serious problems in networked environments ; from disturbing normal network operations to damaging computing resources. Among them denial of services are considered as critical attacks that directly exploit network packets to degrade availability. In this paper, we classify the types of denial of services in the network layer and develop detection methods that can keep the network from the classified denial of service attacks. The methods are then merged into an integrated denial of service detection algorithm that is scalable to detect new denial of service attacks.

In physics education, language is an fundamental learning tool as in other subjects. In writing activity, students can get fair opportunities to express their own ideas during the class. Even though there are various styles of writing, students are usually supposed to make a report in their science classes. But there have been few studies in science education on the tasks and features of student's science writing. In this research, different styles of writing tasks were designed for science classes, and students' writing was analysed in terms of conceptual and emotional aspects. Also the usefulness of each task type was discussed relating to school physics education. Four types of writing, i.e. , , , and writing were developed, and 'The reflection of light' was selected as the theme and given to students. Four types of writing were analysed in this paper. In each type of writing, students showed different features in their conception. They also showed emotional expressions in imaginative writing types, that is, and types. Based on these results, it is recommended that in physics teaching various types of writing need to be designed, developed and applied according to the aim of a particular lesson.

In order to maximize customer satisfaction and provide differentiated customer-oriented marketing strategies, it is important to understand the essence of consumer behavior and characteristics of their market segmentation. Therefore, this study explored the relationships among five different food-related lifestyle (i.e., health, fashion, taste, economy and safety oriented), positive emotion, and satisfaction. An analysis of 338 samples drawn from college students who visited coffeehouse at least once in the previous months was performed. The results revealed that, taste, economy, and safety oriented lifestyle significantly affected positive emotion, and positive emotion significantly affected satisfaction. The findings highlight the significant role of coffeehouse customer food-related lifestyle toward positive emotion in the formation of satisfaction, and therefore generate theoretical and practical implications for the coffeehouse industry.

On-line community service should be considered with sociability and usability as well in website development because community in general is composed of various social factors. But, most on-line community services are developed and operated without having correct concepts and strategies concerning social factors. For that reason, community services in most web sites are not that successful. In this paper, twelve social factors are identified for developing community service evaluation system. Those factors are as follows: 1) Purpose, 2) Identity, 3) Reputation, 4) Governance, 5) Communication, 6) Groups, 7) Environment, 8) Boundaries, 9) Trust, 10) Exchange, 11) Expression, 12) History. Eight different types of community services are evaluated to see variations of 12 social factors. As a result, each types of community services has different types of value variations. The evaluation diagrams of each type will be used as a guideline for comparison and this comparative research will tell designers future development direction of their community services.

오늘날 지속가능한 발전의 주요 목적으로서 환경의 효과적 보호와 신중한 자연자원의 이용이 강조된다. 이와 같은 목적들을 성취하기 위해서 종합적인 경관 정보가 필수적이다. 한국의 경우, 도시화는 전통적인 농촌 경관 변화, 산림 손실과 단편화 등 많은 환경 문제를 야기했다. 특히 산림이 높은 생물 다양성 가치를 갖고 있는 한국으로서는 산림 손실과 단편화는 생태관점에서 보면 아주 치명적이다. 현재 개인 또는 공공 부분 개발 프로젝트를 위한 환경 영향 평가의 일부분으로 시각 경관 영향 평가가 요구된다. 그러나 이런 시각 경관 영향 평가는 단지 전체 경관의 일부분의 경관 정보만을 제공하고, 특히 현재 경관 평가에서는 경관의 생물 다양성 가치를 평가하지 않는다. 본 연구는 이와 같은 문제점들을 극복하고 한국 상황에 맞는 지속가능한 경관 계획을 위한 필수적인 종합 경관 정보를 제공하기 위해서, 경관 특성과 생물 다양성 가치 평가를 위한 생태 이질성 지수를 결합한 진보된 경관 특성 평가 방법론을 제시하는데 그 목적이 있다. 이 방법론을 통해 경관 특성 평가에서 12가지 경관 특성 유형(type)을 분류하였고 그것의 분포, 경관 특성적 형태, 경관 특성에 부정적인 영향을 줄 수 있는 개발 압력 등을 분석하고 서술하였다. 분석 결과, 주택과 산업 단지 개발, 농지 형질 패턴 변경, 수변 공간 개발 등이 주요 개발 압력으로 나타났다. 경관 생태 이질성 평가 결과에서는 도시근교 지역과 농촌 경관 특성 유형 지역에서 잠재적 생물 다양성 가치가 높았다. 산림 지역 경관 특성 유형에서는 잠재적 생물 다양성 가치가 중간 수치로 나온 반면 도시 경관 특성 유형에서의 잠재적 생물 다양성 가치는 아주 낮았다. 비록 제한된 데이터와 경관 생태 이질성 지수 사용으로 인한 문제점들(스케일 종속적, 변화 패턴이 예측하기 힘든 지수, 자의적인 분류시 다른 결과 발생, 더 종합적인 생물 다양성 잠재력을 평가하기 위해서는 더 많은 다른 경관 생태 지수 필요 등)이 제기되었지만, 이 연구에서 제시된 진보된 경관 특성 평가 방법론을 통해 얻은 종합적인 경관 정보가 지속가능한 경관계획을 할 때 어떻게 잘 활용되어질 수 있는지 예로써 증명하였다. 그 결과 진보된 경관 특성 평가 방법론이 지속가능한 경관 계획을 위한 수단으로 사용될 수 있을 것으로 사료된다.

The Office for Government Policy Coordination announced in 2006, september that a scheme of pre-signal would show remarkable outcome to reduce traffic accidents. Therefore, the Ministry recommended applying preferentially the pre-signal scheme to enhancement projects for high accident frequency areas. In case that the suggested pre-signal was unilaterally introduced to the enhancement projects at intersections, it might rather cause a big trial and error in terms of traffic safety. Hence, on the basis of quantitative analysis, this study was to indicate a pre-signal's effectiveness to reduce the traffic accidents, to illustrate a trend of the accident type due to the pre-signal, and to introduce intersection type that could be appropriate for the pre-signal. The methodology adopted Comparison-Group Method which was developed by Hauer. Through this methodology, overall effectiveness to reduce the accidents is considered positive but individual effectiveness by intersection and by accident case was different. All cases of the accidents at small scale intersection demonstrated positive results to reduce its accidents, while in case of frontal collision and side-right angle collision out of the accident types, the installation of pre-signal rather caused a negative result increasing the accident in terms of the traffic safety. I hope that this study would be a useful reference for future development of the estimation of accident effectiveness. Thus, when the pre-signal is being installed in the big intersection, it is recommended operating the installation concerning carefully improvements about muliple aspects as traffic operation, traffic facility, human factor etc.
