The findings of this study indicate that intangible cultural properties are worth preservation and transmission and should be considered as very important as tangible cultural properties. If the studies of intangible cultural properties are continued focusing on their characteristics and formational system, they can be expressed more properly by adding new interactive elements to database and expressive requisites. New techniques introduced in this study are believed to provide people with most reasonable and developmental motives for expression of the existing intangible cultural properties. Concerning Korea's cultural properties centered on intangible cultural properties, information construction should be made with a new idea of information based on database from the previous studies. The result will be able to set an important factor to give wide publicity to our cultural identity, which is currently shown in the process of background communication, and serve as a foothold to deliver exact information to our descendants. The intangible cultural properties are our people's mental cultural heritage resources. If museums or initiator groups, which are organized to spread cultural heritages, can use them as the subjects of exhibition through information construction and visualization, it will function to maximize the educational effect of transmitting our national mental world. The development of digital environment will provide the optimum conditions and tools making it possible to visualize intangible forms and ideas in a virtual cyber space. Given these viewpoints, steady studies and efforts for the improvement of Korea's cultural image should be made in the way of intangible cultural properties as well as tangible ones. They start from the country's accurate appreciation of cultural properties and are embodied in systematic adjustment and relationship between interdependent elements.

사판 훈련이란 모래와 석회로 만든 훈련장 모형을 이용하여 수행하는 실제 군사 작전에 대한 모의 훈련으로서 시간적, 공간적, 경제적인 제약을 극복할 수 있는 효과적인 훈련방식이다. 전통적인 사판 훈련은 모래와 석회로 만들어진 훈련장의 특성상 정확한 지형의 표현 및 보존이 어렵고 사실성이 떨어지며, 사판 내부에 많은 정보를 포함시킬 수 없는 등의 문제점을 가지고 있다. 본 논문에서는 증강현실의 관점에서 접근하며, 사실적으로 묘사된 가상의 사판 환경을 바탕으로 하는 효율적인 군사 훈련 브리핑 도구를 제안한다. 가상 전술지도를 통해서 학습자는 마커와 텐저블 인터페이스의 간단한 조작만으로 가상의 군사 훈련을 실감나게 수행할 수 있다. 뿐만 아니라 사판 내부에 포함된 실시간 상황 정보를 통해 보다 폭넓은 시각에서 전체적인 작전 상황에 대한 유기적인 판단이 가능하게 된다. 텐저블 인터페이스는 현실세계에 있는 사용자와 가상의 물체를 현실세계에 증강 시켜주는 시스템 간의 상호작용을 담당함으로써 사용자에게 직관적이고 다루기 쉬운 콘텐츠 저작 환경을 제공한다. 본 논문은 효과적인 군사 훈련을 위한 새로운 형태의 군사 훈련 브리핑 도구를 제안함으로써 군사 학습에 대한 효과를 증대시키고, 군사 훈련 내용을 추후 활용할 수 있는 콘텐츠로 제작이 가능함을 보였다. 이는 증강현실의 새로운 응용 가능성에 대한 제시라고 말할 수 있다.

The purpose of this study was to identify the relationship between the levels of job satisfaction and self-evaluated foodservice quality of dietitians in elementary schools. Out of 130 questionnaires distributed to the elementary school dietitians in In-cheon, 127 were returned and analyzed (98% response rate). The questionnaire included two multiple-item scales for measuring job satisfaction and foodservice quality, respectively. All the items in the scales were coded 1 to 5 for certainly no, no, neutral, yes, and certainly yes and grouped by using factor analyses. Most of the responding dietitians were working for schools in urban areas and had independently-managed on-site kitchens. The 23 items measuring job satisfaction were grouped into 4 factors: Job Duty, Job Condition, Physical Work Environment, and Organizational Environment. The satisfaction score was the highest for Organizational Environment with a value of 3.38 and the least for Physical Work Environment with a value of 2.08. The 22 items measuring foodservice quality were grouped into 5 factors and the mean scores of the levels of Cleanliness, Internal Food quality, External Food quality, Intangible Service Environment and Tangible Service Environment were 4.20, 3.89, 3.54, 3.45 and 2.64, respectively. The levels of job satisfaction and foodservice quality were positively associated with a correlation coefficient of 0.288 (p < 0.01). In particular, the level of job satisfaction was positively associated with foodservice quality in the aspect of Cleanliness, Internal Food Quality, and Intangible Service Environment. The results show that improving dietitians' job satisfaction could contribute to increasing the levels of foodseivice quality of elementary schools.

This paper considers the effect of "comprehensive rural community improvement project" in terms of three factors - physical environment, rural tourism, socioeconomic and analyzed the path effect leading to the final outcome - the quality of life of residents, using covariance structure analysis. By doing so, this study looks into why residents prefer the improvement of a physical environment that takes a public nature. The analysis showed that the socioeconomic effect did not have an immediate impact on the improvement of quality of life of residents at a significance level of 5%, whereas the improvement of physical environment had a static effect on the quality of living at a significance level of 1%. Residents' preference for "hardware" or physical environment may be attributed to lack of their understanding of human factors such as social capital. However, analyzing the impact of specific contents of the project on performance, it is found that as projects fail to generate a tangible socioeconomic effect, residents strategically prefer the repair of their physical environment such as public facilities that directly affect their daily lives, so that they can maximize an improvement of the quality of living. Hence, this study suggests that instead of attributing the failure of rural community development projects to residents, macroscopic problems of rural communities and specific contents of projects should be dealt with before the success of any project can be discussed.

In this paper, we propose the valuation frame of the IT(Information Technology) ventures using ROV(Real Options Valuation) model. Generally, ROV can comprises the traditional valuation method such as DCF(Discounted Cash Flow), which can measure only the tangible value of a firm from the expected future earnings, in that ROV can additionally measure the intangible value such as the strategic value of a firm in the uncertain environment. We set up the hypothetic IT venture future investment plan and assume that there are a growth option and a switching option consequently along the investment time horizon, which are caused by each characteristics of ventures and IT technologies, especially modularity. In the case that there are several embedded real options in the firm's investment plan in a row, we should apply the compound option pricing model as a real option valuation model in order to consider the value interaction between real options. In an addition, we present the results of optimal investment timing analysis using real options approach and compare them. with those of the original assumed investment timing.

This article aims to analyze the experience of designing and operating a class model linking undergraduate and graduate students in engineering education and suggest its development direction. To achieve these objectives, the undergraduate-graduate linked class model was applied to community problem-solving education and a case was analyzed. It also specifically presented the process of how we design the class model and what the actual operational performances and improvements are. This study found that undergraduate and graduate students could build integrated and horizontal cooperative relationships in their classes through undergraduate-graduate linked education and, particularly, graduate students could gain meaningful educational experiences. However, it was difficult to obtain tangible performances through the team activities of these students within a semester. In order for engineering colleges to operate undergraduate-graduate linked education, it would be necessary to provide a longer and more systematic educational environment and better curriculum. The study tried to seek specific tasks and ways to improve them.
