To promote the remodeling project it is important to get apartment residents' consent. It is significant variable to determine project to progress smoothly from planning stage which committee of association establishment sets up to establishment stage of association. On average, it takes about 1~1.6 year in planning phase which means before construction phase of remodeling. Therefore, it is very important issue to get apartment residents' consent in planning phase. In this research, we focused on residents' opinion and proposed solution of conflict with gathering residents' opinion to proceed remodeling project. By setting particular remodeling situation, related residents represented as agents made effort to efficient coordination to reduce total duration of decision making. Therefore, we proposed multi-agent based on fuzzy inference to simulate behavior of decision making on remodeling project effectively. From this method, optimal alternative is selected by considering each agents' attributes which represented by fuzzy set. This research will develope to further research for realizing concrete multi-agent based on fuzzy inference considering all stakeholders in remodeling project.

In this study, an effort was made to find out more effective methods for vegetation establishment on denuded forest land along Cheon Bo Mountains, This area has serious sheet erosion as a major erosion process and parent material is granite gneiss which is known as one of the most erosive materials. Lespedeza bicolor, Arundinella hirta and Robinia pseudoacacia were used as ground cover species. Seeding methods were open broadcast seeding and broadcast seeding with straw mulch, dill seeding with 10cm and 20cm width, and spot seeding with 20cm and 30cm diameter. 1. On slopes less than 30 degrees, broadcast seeding method with straw mulch was the most effective way to establish vegetation cover. 2. On steep slopes more than 30 degrees, 10cm drill seeding method was more effective than the other methods. 3. Soil Texture has an influence on vegetation establishment governing soil moisture condition. Coverage and fresh weight were increased with the fine material qantity in soil. 4. In process of year, coverage was increased with fresh weight. On the other hand, survival decreased.

Purpose: The establishment of the trauma system has changed the quality of trauma care in many countries. As one of the first designated level I trauma centers in Korea, we hypothesized that there were changes in laparotomy patterns and subsequent survival rates after the center was established. Methods: This was a 5-year retrospective study of all severe hemoperitoneum patients who were transfused with more than 10 units of packed red blood cells (RBCs) within 24 h of hospitalization. Variables related to trauma were collected throughout the study period, and the patients admitted before (period 1) and after (period 2) the establishment of a trauma center were compared. Results: Forty-five patients were managed from January 2009 to March 2015. The baseline patient characteristics of the two groups, including age, Injury Severity Score, blood pressure, and hemoglobin levels, were similar. The time to the operating room (OR) was $144.3{\pm}51.5$ min (period 1) and $79.9{\pm}44.1$ min (period 2) (p<0.0001). Damage control surgery (DCS) was performed in 17% of patients during period 1 and in 73% during period 2. The number of actual survivors (n=10) was higher than expected (n=8) in period 2. Conclusion: This is the first study analyzing the impact of a trauma center on the management of specific injuries, such as severe hemoperitoneum, in patients in Korea. During the study, the time to OR was shortened and DCS was used to a greater extent as a surgical procedure.

There is a high potentiality of large traffic accident due to the dense fog when road is developed along the coast or river. The establishment of national level control system against the fog is necessary because the accident due to the creation of fog has a high fatality ratio than other weather conditions. The selection method for the frequent foggy area on highway was suggested to control the fog on the highway effectively because the establishment of the countermeasure against the fog in every range in highway is difficult practically. 44 ranges where the fog control is necessary throughout the year and the 45 ranges where the control is necessary in specific months were selected from the result of application of the weighted value on each visible distance data except the fog with beyond 250 m visible distance which does not affect on the safe driving out of the surveyedjsh fog visible distances. The preferential fog control countermeasure shall be provided to prevent the traffic accident and to reduce the severeness of the accident in case of fog creation for 89 ranges which were selected for frequent foggy area in highway.

There is no official landscape architectural organization in the current government organization in Korea. Therefore, it is necessary to establish the landscape architectural organization which will carry out the works of the special landscape architectural interest and create the new services with other interested government offices. The contents of the study are as follows; 1. A legal basis for the establishment of the landscape architectural organization is the demand for the introduction of the landscape architectural organization which has 5 types(urban planning, architecture, land register, land surveying, civil work) of the special groups to official organization by changing the 1 article of the Official Appointment Regulations. 2. Theories of law of equality for everyone(the Constitution of Korea : §11(1)), the rights of having pleasant residential life(the Constitution of Korea : §35(3)) and the national duty of employment increase(the Constitution of Korea : §32(1)) are reviewed to provide the legal reason of establishing the landscape architectural organization. 3. With the addition of new landscape architectural organization, it could expand the areas of landscape architects by adding of new landscape architectural subjects into official examinations for government employees. Also it is necessary to exempt the test for those who have licenses and to give additional points in evaluation their works at the end of year to the people who have licenses. 4. The reasons for the creation of new landscape architectural organization into the present official organization are acquired from the derivation of 23 present regulations referring to the landscape architects, the existence of the landscape architectural administrative departments belonging to the Metropolis of Seoul, and the favorable result of the questionnaire on the establishment of the new organization. Hereafter the lawyers should be cooperated with landscape architects to initiate the related principles of law, and it is necessary to analyze each text of the related laws in detail to establish the landscape architectural organization by means of the joint studies.

As year passes, terrorism is gradually increasing. Its target has becom various and arbitary, and recently, terrorists are aiming for national major facilities wich include multiplex facilities. Although special security guards took charge of its defence system from 2002, they have failed to establish its system firmly due to some institutional inertia. And 'Professionalism' appeared to be the mattter, according to the spot-probe and interviews. The purpose of this essay is to devise measures to develop sepecial security system including its specialization through investigating current educational training system. In order to attain professionalism, establishment of new proffessional school, division of current education system(into common education and full-course education), and reinforcement of substantial inspection activity should be preceded. Moreover, inspection activity should include standards for engaging instructors, establishment of compilation committee for editorial supervision, and establishment of clear educational policy. I hope the developmental measures in this essay to be speedily actualized with endeavor from police, security association, academic circles.
