The purpose of this study is to explore how to make use of the light and expression methods to embody phenomenal space by considering the representation techniques and characteristics of a variety of 'Phenomenal light' in his works focused on the Steven Holl's views that thought the light as object of creating space. The process is summarized as follows: (1) Study on the relationship between light and color, Classify concept and type of phenomenal light by phenomenal color (2) Consider the characteristics and expression methods of the phenomenal light in the Steven Holl's architecture (3) Finally, organize the concepts and representation techniques of phenomenal light, and then present method to embody phenomenal space by light. According to this, the results are as follows: (1) Perceptual color by the light of the sense forms a variety of perception and texture of light and shadow according to the contrast of shades and the change of materiality, thus embodying multisensory space with the light as the medium approach that helps to experience formal and tactile senses. (2) Spatial color by the light of volume distinguishes the flow and movement of sight, and embody inducing space with the light as Atypical activity that forms atmosphere of space through concentrated or overlapped mass of light and darkness. (3) Existential color by the light of the light source visualizes the existence of the uncertain light, and embody the receptive space with the light as emotional communication that forms symbolic and psychological meaning through metaphorical phenomena of colored light.
To examine the gap between physician's perceived importance and performance of care and to identify factors associated with the gap. A self-administered questionnaire survey was conducted with 91 physicians working in a University hospital in Seoul. The respondents were asked about their perceived importance and actual performance of interpersonal care on a 5-point Likert-type scale, indicating a higher score as higher importance and performance. Interpersonal care was measured by questions modified from the Korean Standard Service Quality Index, which are grouped into 6 categories: basic services, extra services, reliability, courtesy, convenience, and tangibles. Multiple regression analysis was conducted to find out physician characteristics associated with the gap. All of the 6 interpersonal care categories showed lower performance than perceived importance. The respondents tended to have a worse performance than perceived importance as the number of patients per outpatient care session ($\beta$=-0.0204, p<0.05) and the need for customer satisfaction education increase ($\beta$=-0.2226, p<0.05). Female physicians ($\beta$=0.2336, p<0.05) and those with higher job satisfaction($\beta$=0.0096, p<0.05) showed a better performance than perception. Overall, it appears that lower quality of interpersonal care was delivered to patients than the desired level considered by the responding physicians. Based on the regression analysis results, it is suggested that reducing patient volume per session, fulfilling education need for customer satisfaction, and improving job satisfaction may contribute to reduce the gap between physician's perceived importance and performance of interpersonal care.
Purpose - Identify the priorities of important factors through SWOT/AHP analysis method for vitalization of global marine sports in Korea. Through this, we will identify prerequisites and strategies for Korean marine sports to become a global powerhouse, including revitalizing the Korean Wave for Chinese consumers. It also revitalizes global competitiveness and draws policy implications. Research design and methodology - Through interviews with experts and literature data, elements of important opportunities, threats, strengths and weaknesses of marine sports are summarized. Based on this SWOT, the AHP technique is applied to determine which is first and what is important between the factors that save opportunities and increase strengths, and measures to cope with threats and factors that complement weaknesses. Through this, the priority factor of experts suggests a plan for activating strategic marine sports. Results - First, the current status of marine sports in Korea and the perception of consumers are grasped through current data and literature research. Sub-elements are derived based on the theoretical literature on SWOT elements and opinions of experts. Prioritization is identified based on the AHP questionnaire of Korean experts. Conclusions - The strategy was derived through SWOT/AHP analysis, and the following implications were obtained. Regionally, Busan is psychologically and geographically adjacent to China and Japan. It is also an area where human exchanges are actively taking place along with the volume of imports and exports. Due to the increase in China's marine sports industry and population, it is necessary to expand the scope of Korea to marine sports beyond cosmetics, dramas, movies, and Korean waves (Hallyu) stars.

The multimedia that is characterized by multi-media, multi-features, multi-representations, huge volume, and varieties, is rapidly spreading out due to the increasing of application domains. Thus, it is urgently needed to develop a multimedia information system that can retrieve the needed information rapidly and accurately from the huge amount of multimedia data. For the content-based retrieval of moving picture, picture information is generally used. It is generally used when video is segmented. Through that, it can be a structural video browsing. The tasking that divides video to shot is called video segmentation, and detecting the cut for video segmentation is called cut detection. The goal of this paper is to divide moving picture using HMMD(Hue-Mar-Min-Diff) color model and edge histogram descriptor among the MPEG-7 visual descriptors. HMMD color model is more familiar to human's perception than the other color spaces. Finally, the proposed retrieval system is implemented as hardware.

This paper suggests a sensor's placement method for detecting the dilemma zone problem when real-time driver's safety service is provided at signalized intersections by multiple pointed traffic sensors using USN environments. For detecting the dangerous situations from vehicles accelerating through yellow intervals, red-light running and stopping abruptly like as dilemma zone problem, VISSIM(microscopic, behavior-based multi-purpose traffic simulation program) is used to perform a real-time multiple detection situation by changing the input data like as various inflow-volume, design speed change, driver perception and response time. As a result, the optimal interval of traffic sensors is 20~27m, and the initialized sensor location from stop-line is different according to road design speed. Moreover, the pattern of detection about dilemma zone is also different according to inflow-volumes. This paper shows that the method is useful to evaluate the sensor's placement problem based on micro-simulation and the results can be used as the basic research for USN services.
This paper suggests a new approach for providing information for driver safety at signalized intersections. Particularly dangerous situations at signalized intersections such as red-light violations, accelerating through yellow intervals, red-light running, and stopping abruptly due to the dilemma zone problem are considered in this study. This paper presents the development of a dangerous vehicle determination algorithm by collecting real-time vehicle speeds and times from multiple point detectors when the vehicles are traveling during phase-change. For an evaluation of this algorithm, VISSIM is used to perform a real-time multiple detection situation by changing the input data such as various inflow-volume, design speed change, driver perception, and response time. As a result the correct-classification rate is approximately 98.5% and the prediction rate of the algorithm is approximately 88.5%. This paper shows the sensitivity results by changing the input data. This result showed that the new approach can be used to improve safety for signalized intersections.
This study was designed to understand the change of rural landscape and to consider problems followed by development restrictions lifted for Neobiul Village in Ansan City, Korea. Physical landscape changes were comprehended by a field study and interview with local residents, and the residents' perception regarding the landscape changes were analyzed with the REP investigation method. The results can be summarized into the following three points: First, due to the lift of development restrictions and the deregulation of land use, the number of factories and warehouses for rent increased, which became a new source of income for the village. Second, the residents' complaints increased due to the increased traffic volume and waste from a sudden influx of factories and warehouses, which could not be handled by a small farming village. Third, a mix of landscape combining both city and farming village was formed due to the influx of external capital and the need of rental income, although the residents rather wanted Neobiul Village to become a residential village than a factory location. Furthermore, even in the farmlands near the village where development restrictions have not been lifted, the level of dependence on the farming industry has decreased as a consequence of the increase in farmland rent and weekend farms. This paper confirmed that the change of rural landscape followed by lifted development restrictions affects the everyday life of residents living in Neobiul Village. This study has significant implications in that it suggests a case showing the effects of national policies such as lifting development restrictions for rural villages in suburban areas.

Recently, the rise in the housing burden on young couples has led to a serious housing poverty among young people. The number of young people who move into public rental housing is very small because the eligibility for public rental housing is determined based on income, the status of housing subscription, and the size of the household. With this background, the government launched a public rental housing program called Happy Housing Project, which gives young people the priority to move in first. However, the program is facing an obstacle due to the opposition of local residents. The purpose of this paper is to examine whether public rental housing can induce the NIMBY syndrome through conducting a literature review, followed by an analysis of NIMBY syndrome around the currently supplied Happy House development areas, and finally analyzing the household characteristics in order to identify which households were prone to the NIMBY syndrome. To confirm the existence of the NIMBY syndrome, this paper comparatively analyzed the two groups using binary logit analysis. The first group consists of households that are against the Happy House policy, and the second group consists of households that are aware of the Happy House development taking place in their neighborhoods, and are against the development. This study considered the households against the Happy House development in their neighborhoods to have NIMBY tendencies, and focused on comparing the households with NIMBY tendencies with those who do not. To confirm whether the residents around the Happy House neighborhoods have NIMBY tendencies, this paper compared the two groups and confirmed that about 4% of the households have NIMBY tendencies. This paper subsequently analyzed the households with NIMBY tendencies, and found them to have a higher number of children, reside in apartments and reside in owned homes. The volume of the 2018 Happy Housing (35,000 households) is three times higher than that of 2017. The present study aims to analyze the tendency of residents who oppose the construction of Happy Housing so as to derive policy implications for the smooth provision of public rental housing.

Stock prices are influenced by a number of external factors, such as laws and trends, as well as number-based internal factors such as trading volume and closing prices. Since many factors affect stock prices, it is very difficult to accurately predict stock prices using only fragmentary stock data. In particular, since the value of a company is greatly affected by the perception of people who actually trade stocks, emotional information about a specific company is considered an important factor. In this paper, we propose a deep learning-based stock price prediction model using sentiment analysis with news data considering temporal characteristics. Stock and news data, two heterogeneous data with different characteristics, are integrated according to time scale and used as input to the model, and the effect of time scale and sentiment index on stock price prediction is finally compared and analyzed. Also, we verify that the accuracy of the proposed model is improved through comparative experiments with existing models.
