문화콘텐츠는 지역 관광산업을 발전시키는데 핵심적인 요인으로 인식이 되어 전 세계 많은 국가들이 자신들만의 문화콘텐츠를 개발하기 위하여 노력을 기울이고 있다. 특히 우리나라뿐만 아니라 전 세계적으로 도시재생을 통한 문화콘텐츠 개발에 많은 관심을 가지고 있는데 그 이유로 도시에서 상대적으로 경제적·문화적으로 낙후되거나 사용하지 않는 유휴공간을 새로이 리모델링함으로써 도시 내 유휴공간을 지역의 특화된 문화예술 공간으로 구축함으로써 하나의 지역 특화 관광산업으로 발전을 하고 있기 때문이다. 따라서 본 연구는 SERVQUAL을 통해 유휴공간을 통해 제공되는 문화콘텐츠가 관광산업에 어떠한 영향을 주는지를 살펴 보고자 한다.

In the past, the rooftop was a place where a water tank was to be installed, and a space of secretion and concealment such as a warehouse exposed in the air. It was because it was judged to hinder the beauty of a city as a whole without having any functional value per se. However, the roof portion is increasingly being utilized for a space such as a cafe, a pub, and a lounge as the rooftop is highly recognized as a place for leisure activities other than an idle space in modern times. Nonetheless, there are no detailed ordinances and criteria corresponding to such circumstances. For example, in case of the rooftop space, the building code applied to the rooftop space is a legal system when the rooftop was an idle space in the past though people have now accessed more increasingly to the rooftop than in the past. This study investigated the definition on the rooftop space evolved in accordance with the change of the rooftop space and the related legal system in Korea, and conducted a survey for the purpose of performing the field investigation for the analysis of physical status in 117 spaces that form the rooftop space in the rooftop of small-scale commercial facilities with 2 stories through 4 stories in Korea and analyze the recognition of users and analyzing the recognition of users. We analyzed the problems in the rooftop space through analysis of derived data, and suggested improvement plans.

The purpose of this study is to analyze the influence of visitors' sense of place on regeneration space using idle industrial facilities on visitors' satisfaction and length of stay. For this purpose, this study selected Mullae Art Village in Seoul as a study site and conducted a questionnaire survey focused on visitors. The results of an exploratory factor analysis (EFA), reliability analysis and multiple regression analysis show that among the sense of place factors of Mullae Art Village 'Attractiveness' and 'Meaningfulness' have a positive influence on visitor satisfaction and length of stay. 'Attractiveness' was found to be the most influential factor. 'Historicity' was found to have no effects on visitor satisfaction and length of stay. In addition, visitor satisfaction has a positive influence on duration of stay. These results suggest that it is important to analyze the sense of place of idle industrial facilities. It will be a useful guide for urban space planners in revitalizing and establishing a marketing strategy for these spaces.

급격하게 변화를 거듭하고 있는 현재의 사회에는 사용하지 않거나 잊혀져가는 유휴공간이 많이 늘어나고 있다. 이런 공간을 기획하여 재탄생한 문화공간은 지역사회에 큰 영향을 주고 있다. 따라서 본 연구에서는 유휴공간의 성공적인 문화공간기획이 이루어지기 위한 방법으로써 공간정체성의 보존이 중요함을 말하고자 한다.

It is discussed how to locate idle vehicles of AGVS on unidirectional guide paths. The problem is modeled as a median location problem on a cyclic network. The characteristics of the optimal location are analyzed and some useful properties are suggested to reduce the solution space. Based on the properties found, several special types of networks - a pure single-loop type, the loop type with a single branching intersection and the loop type with local branching node - are also analyzed as well as the general cyclic network. In each case of the networks, a solution procedure is suggested. Some numerical examples are provided to illustrate the algorithms developed.

In this study 'forest design in waterside unused land' of 'waterside area' in the specificity that multilateral, including landscape, recreation, social and environmental aspects in the space, taking into account by multiple factors :Raise 'practicality' than a functional management and police to hang out with, each element is usually way to improve the beauty. There is currently carried out waterside green area creation, which is artificial plantation and open spaces only emphasizing 'landscape' with lacking multi-function purpose, as a 'forest design in waterside unused land' strategy but it should be lowered by performance in this strategy. And the study suggested a strategy which prepared cultural and social infrastructure to be able to attract different fund and build local character as an alternative demand plan considered environmental character as a top priority.

This study focuses on the state space model and the design of a state observer for the slip dynamics between rolls in STS cold cluster mills. First, a mathematical model of the roll slip is given as a nonlinear differential equation. Then, by using a Taylor series expansion, it is linearized as a state space model. Next, by using Gopinath's algorithm, a minimal-order state observer based on the state space model is designed to estimate the angular speed of all idle rolls except for an actuated roll that is measureable. Finally, a computer simulation is used to validate that the proposed state space model very well describes slip dynamics between, and moreover, the state observer very well estimates the angular speed of the idle roll.

As the importance of economic value of culture has increased, governments have set a strategy to secure national competitiveness through cultural art. One of concrete ways is establishing a cultural space by using idle facilities. This study aims to analyze publicness of Seoul Art Space, suggest ways to improve the facilities of creative space and provide basic date for the further plan of creative space. The object of this study is 8 facilities from Seoul Art Space which is operated by City of Seoul. Through literature review, we extracted 5 elements(each element has 4 sub categories) for publicness(accessibility, openness, convenience, historical connectivity and stay time) and to evaluates publicness of the Seoul Art Space, we analyzed these facilities based on these elements. The results are as follows: The publicness of Seoul Art Space acquired 96.9%(100% is 64 points) for stay time, 95.3% for convenience, 90.6% for accessibility, 73.4% for openness and 62.5% for historical connectivity. For the openness, we suggest to use glass materials and open the space to the public. To improve historical connectivity, we suggest to determine appropriate theme for a particular space or area and set a function of buildings for the differentiation.

In scheduling multi-unit projects, several alternatives can exist in network construction due to repetitiveness of their activities. Project duration is affected not only by the duration of each activity but also by the arrangement of repeating activities in such projects. This paper provides a network compression method that assigns predecessors to each activity to minimize its float time. Different to the previous efforts that utilized line of balance as the base scheduling-model, this research adopts precedence diagram arranged in two coordinates, the space axis and the resource one. This method seeks the most appropriate predecessors for each activity in each direction of the two coordinates for the purpose of minimizing the idle resource and space. This activity arrangement method was applied to a multi-unit apartment-construction project, to prove its capability of network compression. The result shows that the method successfully sought room for saving construction duration by changing the activity arrangement. The network compression method presented in this research can be utilized in multi-unit construction projects such as apartment complex projects.
