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.

This study was to identify the dimensions of consumers' attitudes toward imported casual brands. Another objectives were to examine consumers' attitude according to the preference group, and to ascertain the imported casual brand images. The 55 Likert type questions were selected through the results of self-questionnaire analyses. 520 females aged between 20 to 29 in Pusan responded to the second questionnaire of consumers' attitudes and brand images toward imported casual brands. The results were as follows: 1. For final factor analysis, 56 selected from 85 questions were subjected to the principal component analyses with orthogonal rotation after extraction of 5 major factors. 2. Five dimensions are brand's uniqueness and good quality, high prestige, incongruity with native emotion and ethnocentrism, conspicuous consumption, and reasonable purchasing advantages. These factors explained 45.0% of total variance. 3. Five dimensions were different according to the degree of preference. For preference group, they purchased the imported casual brands by uniqueness, good quality and reasonable purchasing advantages. For non-preference group, they disliked the imported brands by incongruity with native emotion, ethnocentrism, and conspicuous consumption. 4. Preference group had 5.47, whereas non-preference group had 1.76 pieces of imported casual brands for this 2 years. This result suggests that to develop the domestic brands with international uniqueness, good quality, and high prestige, and to improve according to preference group are necessary.

Reinforced Soil Wall has several merits comparing with conventional retaining wall. The conventional method has the limit of wall height, ununiform settlement of the foundation ground, quality assurance of the embankment body, shortening of construction period, economical construction and so on. Basis of previous mentioned things reinforced soil wall is the substitutional method of conventional retaining wall and its necessity is continuously increasing. The embanking material used in reinforced soil wall is generally limited such as a good quality sandy soil, and in many case constructors have to transfer such a good embanking material from far away to construction site. As a result, they would pressed by time and economy. If poor soils could be used embanking material, for example, clayey soil produced in-situ by cutting and excavation, the economical merit of reinforced soil wall would be increased more and more. Likewise, a lot of study about laboratory experimental behavior of reinforced soil wall using a good quality soil is being performed, but is rare study about clayey soil containing much volume of fine particle relatively in korea. In this study, the authors investigated behavior of the geosynthetic reinforced and unreinforced soil walls using clayey soil as embanking material in view of horizontal movement of walls, bearing capacity and reinforcement stress.

프랙탈 화상압축은 원화상을 일정 크기의 블럭으로 분할하고 자기 유사성(self -similarity)을 지닌 유사 영역을 탐색한다. 이 압축방식은 부가적인 코드북의 전송 이 필요하지 않아 높은 압축율을 달성하고 좋은 화질의 재생화상을 제공한다. 이러한 이점에도 불구하고 부호화시 유사 영역의 결정을 위한 복잡한 선형변환의 수행으로 인해 부호와 시간이 증가되는 단점이 있다. 본 논문에서는 블럭의 AC(alternating current)계수들을 이용하여 선형변환의 횟수를 감소시켜 부호화 시간을 줄이는 고속 프랙탈 화상압축을 제안한다. 제안 방식은 기존의 방식과 비교하여 좋은 화질을 제공 한다. 또한, 중요 기밀 데이터를 합성하는 화상 심층암호에 응용한 프랙탈 화상 압축 응용법을 제시한다.

Groundwater is an essential drinking water source in Gyungbuk, South Korea. The primary source of nitrate in groundwater is from nitrogen fertilizers. Efficient management of a small drinking water plant requires a good understanding of its status such as the objective and the cognition of users. The objective of this study is to understand user situation and produce useful user-friendly policy based on user cognition. Most people who participated in this study, should take their groundwater from a good quality source. Even though they would like to have a good facility for getting safe water, they were reluctant to do it due to the cost used. It means that people who drink groundwater have no idea that health safety is affected by groundwater quality. The volume used depended upon personal activities such as agriculture and stockbreeding. We can easily find groundwater with nitrate that exceeds drinking water standards. Therefore, we have to carry out groundwater management with two categories ; 1) drinking water only and 2) others according to objectives in small drinking water systems.

Distributed video coding (DVC) is a new coding paradigm that enables to exploit the statistics among sources only in decoder and to achieve extremely low complex video encoding without any loss of coding efficiency. Wyner-Ziv coding, a particular implementation of DVC, reconstructs video by correcting noise on side information using channel code. Since a good quality of side information brings less noise to be removed by the channel code, generation of good side information is very important for the overall coding efficiency. However, if there are complex motions among frames, it is very hard to generate a good quality of side information without any information of original frame. In this paper, we propose a method to enhance the quality of the side information using small amount of additional information of original frame in the form of hash. By decoder's informing encoder where the hash has to be transmitted, side information can be improved enormously with only small amount of hash data. Therefore, the proposed method gains considerable coding efficiency. Results of our experiment have verified average PSNR gain up to 1 dB, when compared to the well-known DVC codec, known as DISCOVER codec.

The objective of this study is to estimate the load of pollutants caused from the forest area among non-point pollutants within the Juam lake. The surveyed forest area was classified into broad-leaved, conifer, mixed and herbage area by forest tree type. Water quality and flux were investigated under rainfall and non-rainfall, respectively. Then, pollutant loading was evaluated by using the values of unit pollutant loading factor of each point and area of forest zone. Water quality analysis results of runoff by forest tree types were as follows. - Annual BOD, $COD_{Mn}\;and\;COD_{Cr}$ concentration of runoff in conifer area was high, and particle and biological recalcitrant compounds were flowed highly. - SS, T-N and T-P concentration was high in runoff from broad-leaved area, and biological degradable compounds was flowed. - Water quality of water from valley was maintained good under non-rainfall and could be utilized as fresh drinking water. Through water quality standard investigation, a countermeasure establishment was necessary to secure a good quality of drinking water - BOD, $COD_{Mn},\;and\;COD_{Cr}$ concentration of Bo-sung river was higher 1.5 times than other 2 streams, and because of high T-N, and T-P concentration in Songgwang stream, the management for this was necessary.
