This research explores the intension of repeatable guests through on the wedding facilities, employees' service ability, and banquet menu. First, wedding facilities include transportation, parking lots, subsidiary facilities, reception desks, Paebaek Rooms, and waiting rooms for brides. Secondly, according to the analysis for service quality of hotel wedding feasts, respondence and sympathy were not be fully considered while good effects showed through materiality, reliability and conviction. Thirdly, hotels will be expected to have re-visiting guests when the guests have good experience on the hotel facilities and satisfying menu. Alternatively, menu would have a negative result if there's not satisfying service. Employees should be aware of the list of menu and can be able to offer a suggestion. In other words, a banquet has to be prepared not only with fresh or seasoned ingredients but with good service to make the guests revisit. Therefore, we should be aware of what our guests want and how to prepare for their satisfaction.

The main object of this study is to develop the infiltration facility that it can be used in grounds, parking areas, roads, pathway, housing etc. As a result, it is much alike in the infiltration method of facility to use permeable concrete, permeable hole and be filled with broken stones. And through this experiment, it was perceived the truth that the state of ground, the groundwater level, buildings around them, the history of submerging and the applicable infiltration facilities are the key. To verify how much the infiltration facility reduce the outflow, we set up the infiltration facility in the test area. In result, it reduced the outflow 89% in 24 mm rainfall, 93% in 12 mm, 51% in 140 mm, 75% in 64 mm and 80% in 54 mm. As the rainfall rate increased, the infiltration increased up to the limited rainfall. And in the limited rainfall, we knew that the infiltration was reduced suddenly. Infiltration is closely related to the state of ground, the rain interval etc. and we will analyze these conditions through the continuous monitoring.

This study was carried out to provide basic data for efficient park management by analysing visitors' satisfaction factors and estimated regression model through questionnaire survey method at Taeanhaean National Park in Korea. Performance(satisfaction) variables as 'touting', 'illegal merchant', 'noise', 'indiscreet use' and 'collection of natural plants or animals', and Importance variables as 'littering problem', 'water pollution act', 'careless cooking' and 'exorbitant pay' were relatively high score. It was clarified that the 'souvenir & special product', 'lack of use program' 'lack of public facility', 'lack of information facility', and 'lack of commercial facility' were 'concentrate here' ones by the Importance-Performance analysis. 'Facility management', 'Use management' and 'Resource management' factors were found out by Factor Analysis and the 'Facility management' was the biggest factor accounting for 32.6% of all. In the estimated model by Multiple Regression Analysis, 'lack of employee's guidance or kindness', 'lack of convenience facility', 'noise', 'lack of facilities to stay' and 'charge of user fee, parking fee' were the variables to impact visitors' satisfaction and to need concentrated management. These results were unique characteristics of marine national park and then the different management strategy and policy from mountain national park were necessary.

The integrated underground space map shows the underground facility(water supply, sewage, gas, electric power, communication, heating), underground structures (subway, underpass, underground walkway, underground parking lot, underground shopping mall, common ward), ground(drilling, coffin, geology) refers to a map constructed so that a total of 15 types of underground information can be checked at a glance on a three-dimensional basis. The purpose of this study is to develop a technology to correct the problem of curved surface processing and the unevenness of underground facility pipelines that occur in converting 2D underground facility data into 3D-based underground space integrated map(3D underground facility model). do it with. To this end, we first investigated and reviewed the domestic and foreign status of technologies that generate data on underground facilities based on three dimensions, and developed a surface correction algorithm and an unevenness correction algorithm to solve practical problems. Algorithms to verify the developed algorithm This applied correction program was developed. Based on the above process, the three-dimensional model of the underground facility could be produced identically to reality. This study is judged to have significance as a basic study to improve the utilization of the underground spatial integration map.

This thesis suggests ways for ensuring the safety of domestic autogas (liquefied petroleum gas) vehicles by conducting comparison and analysis on the status of market diffusion and safety management scheme in foreign countries as well as in Korea. According to the result of the survey on the status of domestic autogas safety management, the national scheme to secure the safety of autogas vehicles seems neither well-organized nor sufficiently-controlled. Actually, the gas leakage check-ups conducted for 5,000 autogas cars revealed that about 4 percent of them had leakage problems. As a result, it was acknowledged that the autogas safety regulations being operated in advanced countries need to be selectively introduced for the domestic autogas industry. Consequently, in line with the recent permission to use autogas as a fuel for subcompact cars etc., this thesis is recommending some methods to enhance the safety management scheme for autogas cars such as the amendment of facility regulations including the ventilation of underground parking lots, mandatory attachment of labels claiming autogas cars and indicating periodical inspections etc.

본 연구는 침투시설의 설치위치와 종류에 따른 유출저감효과를 WinSLAMM 모형을 이용하여 분석한 것이다. 본 연구의 대상유역은 Driveway 38%, Residential Area 8%, Parking Storage 8%, Sidewalk 8%, Playground 8%, 투수유역(Landscaped Area) 30%와 같이 토지이용별로 구획된 총면적 $0.25km^2$의 전형적으로 도시화된 가상유역으로 설정하였다. 침투시설 설치에서 중요한 요소 중 하나인 시설의 포화를 고려하기 위하여 10mm/hr~30mm/hr범위의 강우를 적용하였으며, 설치위치와 종류별 침투시설의 정량적인 유출저감효과를 비교하기 위하여 Residential Area, Parking Storage, Playground와 같은 유역내 불투수유역과 유출구에 해당하는 Outfall에 일정한 규모의 침투트렌치와 침투통을 설치하였다. 침투시설은 강우의 크기에 따라 시설의 포화가 진행되며 일정 규모 이상의 강우 발생시 침투기능을 상실하므로 강우의 크기에 맞는 포화시점을 찾아 적절한 규모로 설치해야하고, 경호우에서 유역내의 침투시설의 가용면적을 증가시키면 유출저감효과도 증가하였으나, 강우가 커질수록 상대적으로 가용면적이 큰 유출구와 차이가 없거나 오히려 더 낮은 유출저감효과가 나타나기도 하였다. 또한 설치위치에 침투시설을 비교한 결과, 경호우의 경우 동일한 유출저감효과가 나타났으나, 침투트렌치가 포화에 이루어지기 전까지는 유출저감효과가 더 높았으며, 유출구에서는 침투트렌치가 침투통보다 더 높은 유출저감효과가 나타났다. 침투시설의 병행설치시 경호우에서는 병행설치의 효과가 없었으나 강우강도가 증가할수록 효과가 뚜렷하게 나타났고, 유역내 침투시설의 병행설치시 가용면적을 증가시킬수록 유출저감효과도 증가하여 경호우 이상의 강우에서 병행설치를 고려되어야한다는 결론을 얻었다.
