The purpose of this study is to consider activation methods of traditional markets in Jinju city through questionnaire and field survey. Research framework is summarized into two categories: physical environment and operation program. The results are as follows: 1) the gross profit on sales has been decreased continuously and the main causes of that have been recognized as insufficiency of parking lots and convenient facilities and deterioration of environment in spite of facilities modernization project; 2) consumers visited a traditional market because of proper price and reliance on goods, etc. However, they were not satisfied with the physical environment such as parking lots and resting spaces and the operation program such as cultural event and performance. In conclusion it was thought that activation methods of traditional market would be related to the improvement plan in the physical aspect such as parking lots, walkway, convenient and crime prevention facilities and in the operation program aspect such as cultural event, marketing, management consulting, information infrastructure, and delivery system.

As the world is trying to establish smart city, unmanned vehicle control systems are being widely used. This paper writes about an unmanned parking control system that uses an adaptive background image modeling method, suggesting the method of updating the background image, modeled with an adaptive Gaussian mixture model, in both global and local way according to the moving object. Specifically, this paper focuses on suggesting two methods; a method of minimizing the influence of a moving object on a background image and a method of accurately updating the background image by quickly removing afterimages of moving objects within the area of interest to be monitored. In this paper, through the implementation of the unmanned vehicle control system, we proved that the proposed system can quickly and accurately distinguish both moving and static objects such as vehicles from the background image.

In this thesis, we explain developing processes of the power transmission system for lift truck. Conventional power transmission system had some problems such as spatial constraints or low speed and high torque problem. Because conventional power transmission system was mainly designed for high speed vehicles. In this paper we developed power shift drive axle specialized for $2.0{\sim}3.5$ ton lift truck. Innovative structure of transmission which is built in inside axle, enables to reduce system weight and size by 40% compared to the conventional power transmission system. Also, it is possible to do additional functions such as auto parking system and anti-roll back system.

To analyze the effectiveness of the safety e-reporting system, the present study carried out analysis of safety e-reporting data reported between September 2014 and July 2019, and selected items for measuring the effectiveness of safety e-reporting. Using these items, the effects of adopting the reporting system for the four major parking violations was analyzed, alongside an analysis of effects in terms of traffic accidents using the unit model. When we count the securement of the tax revenue through measures such as charging fines as the beneficial factor per case, the estimation of the benefit is around 62,000 KRW per case. Summing the two factors up, the total value of citizen's reports pertaining to the big four parking violations is about 275,000 KRW per case. Most of the reports made through the Safety e-Report system are about traffic and facilities. When we calculate the total annual benefit with the representative reporting value defined with traffic and facilities, the system received a total of 1,164,439 cases from 2014 to 2019, while citizens reported 52,721 cases for the big four parking violations from April to July 2019. As the value of a safety report is around the net benefit for last five years is around 27,340,000,000 KRW.

Many new office buildings are being built as intelligent buildings equipped with building automation(HA) systems, office automation(OA) systems, and telecommunication(TC) systems in order to provide pleasant building environment and the ease of maintenance and facility management. Building control systems which are employed in intelligent buildings require varieties of advanced control systems and network systems for efficient integrated management. Design and installation of these types of advanced building control systems take a lot of efforts and also they are costly. In order to design these systems, it is necessary for the designers to have the integrated simulator including proper network system simulation. In this paper, the integrated simulator that consist of HVAC system, lighting system, elevator system, parking system based on the network system is presented. For the development of integrated simulator, AHENA which is the general-purpose software tool for a simulation with reinforced GUI is used.

The definition of an apartment is a building more than 5 stories high and which is the standard law. Currently, the number of apartments is increasing much faster than detached houses. Owning an apartment is a normal trend these days. However, the increasing number of apartments has been increasing the number of apartment fires which also has been making social problems. Therefore, this study was conducted for the fire extinguisher among other fire facilities because it is important for initial fire suppression. The research subject is on the fire extinguisher that is in the underground parking lot of 40 apartment complexes which are more than 10 stories. Survey and analysis were conducted for 80 fire extinguishers. There are two fire extinguishers for each apartment. The result of this study is that all installed fire extinguishers are ABC dry chemical type, 92% of them is 3.3kg and that meet the legal height(less than 1.5m). However, the condition such as appearance, inspection, manufactured year, appearance of signs, material of signs, size of signs, etc. was insufficiency. So improvement of law and system that are fire facility construction, maintenance implementation and additional designation of type approval about sign will be needed in my opinion.

In this study for relieving traffic congestion on the main arterial in Pusan using TSM Techniques, the travel system, roadway system and signal system analyses were dine. Through these above analyses, it was shown that the peak-time periods on the main arterial were shaped between 10 : 00 and 11 : 00 in the morning and between 15 : 00 and 16 : 00 in the afternoon for the business and shopping trips. Especially, there appeared to be about 23% reduction in the average delay when roadway system management including left-turn links increased were done, about 29% reduction in the average delay when signal system management including the signal phases and timings readjusted were conducted, and about 48% reduction in average delay when roadway system and signal system management were taken into consideration simultaneously. Based upon these results, it was concluded that there might be considerably better results in the average delay if the progressive signal system analyses on the arterial were applied with the land and road widths balanced, the difference on the turning vehicles and mid-block volumes readjusted, and roadside parking traffic prohibited.

The Korean hospital industry is rapidly changing along with the competition among hospitals. Until recently it was easy for hospitals to profit even without efficient management and competitive strategies. However, the increasingly intensive competition endanger their profits but also their survivals. Hospital managers have no choice but to seriously consider competitive management and marketing strategies to remain alive and prosper. This study introduces a useful methodology--perception map drawn using multidimensional scaling--for developing competitive strategies, and illustrates its application to developing a perception map of 9 Seoul-based general hospitals. We also suggest the concepts and examples of positioning strategies and patient satisfaction management system. One of the interesting findings is that the Samsung medical center which opened less than a year ago is ranked first in most aspects such as kindness, facilities, waiting time, and parking, and the second in clinical performance just after the Seoul National University Hospital.
