The purpose of this study was to investigate the relations and differences in Korean national image, Korean wave (Hanryu) interest, and Korean beauty service satisfaction of Korean, Chinese, and Vietnamese living in Korea and to lay the foundations for the export of various contents, especially beauty services, through the enhancement of Korea's national image. The present study was conducted from $10^{th}$ June to $10^{th}$ August 2017, by presenting 523 questionnaires to Koreans living in Seoul and another metropolitan area, and to Chinese and Vietnamese students studying in different Korean language Institutes in Seoul and other areas' universities. The basic questionnaire items were analyzed based on frequency analysis. The data on the national image, Korean wave interest, and Korean beauty service satisfaction were reduced by the factor analysis. The effects of each items were analyzed by regression. The differences in three factors were analyzed by ANOVA, and the differences were calculated by mean values. Consequently, it was observed that three factors are mutually affected each other. Therefore, it is necessary to establish a synergetic relationship between the individual factors. In addition, the individual items exhibited higher mean value in Vietnam, China, and Korea in a descending order. This indicates that Koreans are more likely to de-evaluate their cultures than others. Therefore, Koreans should be aware of the excellence of their culture and try to spread Korean culture and technology to the rest of the world with pride.

This study discusses the interacting with deep water waves approaching from deep water based on the linear wave theory and steep sloping sea bottom floor by the numerical procedure. The results of particular interest are particle velocity and acceleration in x, y, z direction wave height amplification factor reflection coefficient and dimensionless pressure distribution on the steep sloping bottom with respect to the various incident wave angle. The wave loads relative to various bottom slopes, incident wave angles and wave periods on submerged breakwater and pipe are represented in comparison with mild sloping bottom the wave load parameters on the steep sloping bottom seemed to be influenced by variation of incident wave angle. In general the particle velocities and accelerations in x, y, z directions on the steep sloping bottom represented larger value or about two than those on the mild sloping bottom according to incident wave angle. However, the wave height amplification factors did not show distinct difference, but the slight variation with respect to the various incident angle showed on mild sloping bottom. The reflection coefficient increased with respect to increase of the incident angle on the steep sloping bottom the results also indicate that the very steep sloping beach produces a rather substantial amount of reflection as we expected. No significant variation of wave pressure was shown on the steep sloping bottom but it represented a certain amount of variation on the mild sloping bottom according to the various incident wave angle. The analysis at the OTEC site also showed similar results.

In China, the phenomenon called 'Korean Wave' has boosted the interest in Korean pop culture, such as TV drama, music and films, and even in the general culture and society. As Korean singers, movie actors and talents become popular beyond acceptance of public culture, those who learn Korean, buy Korean products and visit Korea have emerged. Especially, most Chinese women have used Korean hair cosmetics and the interests in Korean hair cosmetics are increasing, since cosmetic companies entered China early due to Korean wave. Thus, the status of purchase of Korean hair cosmetics is growing day by day in China. In particular, since the environment is established to buy hair cosmetics easily in Myeong-dong which is one of the shopping tourism special districts, many Chinese tourists are crowded there. Based on such phenomenon, this study explored the differences in perceptions towards 'Korean Wave' among Chinese tourists who purchased Korean hair cosmetics in Myeong-dong, and analyzed the factors that largely determine the interest in Korean hair cosmetics and their purchase behavior. Therefore, this study is aimed at contributing to the development of hair cosmetics products and the market amid Korean Wave. As the research methods, 100 answered questionnaires were collected with target of Chinese tourists at 20s and 40s who purchased Korean hair cosmetics in Myeong-dong once 120 questionnaires were distributed. In-depth analysis was conducted and final research data were used. It was confirmed that Korean fever positively affected the Chinese tourists' purchase behavior and satisfaction of hair cosmetics, and the interests in Korean hair cosmetics at 20s were higher than at 40s. People at 20s had higher awareness, satisfaction and intention of repurchase of hair cosmetics compared rather than people at 40s. The research confirmed that Chinese tourists are very interested in Korean hair cosmetics as the pop music craze has led to the general Korean Wave, and differences in such perceptions have led to significant differences in the product purchase behavior.

본 연구는 중국에서 한국 대중문화 수용과 확산에 대해 어떻게 인식하고 있는가를 분석하기 위해 중국 일간지에 보도된 한류관련 기사의 프레임을 분석하였다. 분석 결과 세 일간지 모두 한류 관련 이벤트나 한국 드라마, 영화의 열풍, 한류 스타의 인기 등 특정 이슈에 따라 연도별로 기사 게재 건수에 큰 차이를 보였다. 이러한 보도경향은 기사의 구성방식에서도 나타나는데 세 일간지 모두 한류 현상을 심층적으로 분석하고, 해석하는 주제 중심적 프레임보다 단편적인 한류 현상이나 인물 정보를 감성적으로 전달하는 일화 중심적 프레임을 주로 사용하였다. 구체적인 기사 내용을 살펴보기 위해 귀납적 접근방법을 활용하여 지배적 뉴스 틀을 분석한 결과 한류를 '한국 대중문화에 대한 흥미와 관심'이라는 문화적 흥미 프레임으로 구성하여 긍정적인 평가를 내리는 프레임이 가장 많았고, 경제적 관점에서 한류를 설명한 경제 프레임과 중국 정부 당국의 시점에서 바라본 정책 프레임 기사의 순으로 나타났다. 이러한 뉴스내용의 틀은 일간지의 발행목적에 따라 다소 다르게 나타났다. 공산당 기관지인 ${\ll}$인민일보${\gg}$는 중국 정부의 정책을 보도하는 정책 프레임을 많이 다루고, ${\ll}$인민일보(해외판)${\gg}$는 대외적인 시각에서 경제 프레임을 많이 다루었고 상업지 성격이 강한 경화일보는 한류를 새로운 문화현상으로 다루는 문화적 흥미 프레임이 많았다. 전체적으로 중국일간지에 보도된 한류 관련 기사는 대부분 긍정적이고 호의적인 프레임의 뉴스가 많으며 한국 대중문화를 문화적인 관점뿐만 아니라 경제적인 교류의 관점, 한국과 중국 간의 교류를 활성화하기 위한 정책적인 관점등 비교적 다양한 관점에서 보도하고 있음을 알 수 있다.

In this paper, a new novel technique of seismic survey is introduced to estimate the continuity of inclined pits filled with water, It was assumed that the pits would be connected to an abandoned railway tunnel that might be constructed in the past. Thus, detection of pit end was needed for the design of a new highway tunnel(Yukshimreong tunnel) that was likely to be met with a pit. In the beginning of exploration, no reliable, cost effective method was available. Hence, focus of interest moved toward the high impedance contrast(reflection coefficient k∼0.8) between water and rock. In this special model of sequence rock-water-rock, total reflection occurs and the seismic energy, when it is generated in the pit water, is nearly confined to the pit so that seismic waves can propagate much further within the pit. As a matter of convenience, this is called“tunnel channel wave”. With these considerations in mind, seismic detonator(2g) was used as a source at the entrance of pit, whereas hydrophone chain(hydrophone interval=1m) was placed on the bottom of pit. With this appropriate source-receiver arrangement, desirable down-going and up-going waves could be observed that will help conform the continuity of pits. After about one year, it was ascertained that the inclined pit of interest was just nearby crossed with the newly excavated tunnel, as it was predicted.

Mathematical formulas for multi-dimensional isolation analysis via vibrational power transmission can be derived in a rather simple form when the wave effects of the isolators are completely neglected. With increase of frequency range of interest, however, the wave effects play a very important role and hence cannot be neglected. The formulas get involved accordingly. In this study, a method of equivalent stiffness modeling of the isolators to include the wave effects is proposed in such a way that not only the complexity of the mathematical expressions but also that of experiments of necessity can be reduced. This method is illustratively applied to a two-dimensional vibration isolation system with nonrigid source and base structures.

The interest in numerically-generated, Boundary-Fitted Coordinate Systems (BFCS) arises from the need for conforming the boundaries of the region in such way that boundary conditions can be accurately represented. The parabolic approximation method in solving wave phenomena is known to have a great merit as time-saving method. However, the method shows a disagreement for the wide angle and behind the structure (omitted)

Recently, as the offshore structures are operated in the deep-sea oil fields, interest in the analysis of relative wave elevation around platforms is increased. In this study, it is examined how the analysis results differ depending on the characteristics of the wave probe when interpreting the relative wave elevation in the model test. First, by conducting the wave probe comparison experiment in the two-dimensional wave tank, it is confirmed how the measured values differ according to the type of wave probe for the same physical phenomenon. Two types of wave probe are selected, the resistance type and the capacitance type, and the causes of the difference in measured values is studied. After that, the model test of the semi-submersible platform is conducted to investigate the relative wave elevation. Relative wave elevation is measured with the wave probes used in the wave probe comparison experiment and analyzed to estimate the asymmetric factor and the extreme upwell. The results between the two types of wave probes are compared, and qualitative study for the cause of the difference is conducted by photographing the physical phenomenon using a high-speed camera. Through the above study, it is confirmed that the capacitance type wave probe shows a larger measured value than the resistance type under the breaking-wave condition, and the same results are obtained for the asymmetric factor and the extreme upwell. These results is thought to be due to the difference in the measurement principle between wave probes, which is whether or not they measured water bubbles. This implies that the model test should be conducted using appropriate wave probes by considering the physical phenomenon to be analyzed.

This study separated different factors into the Korean Wave and Korean health food according to the interest in Korean culture among the Chinese living in China. We then conducted a two-step cluster analysis with gender, marriage status, academic background, interest in Korean culture, command of the Korean language and the status of having visited Korea as variables. The subjects were split into a Korean wave-preferring group, highly interested in Korean food as health food group and a low interested group according to clusters, and we then investigated for preference differences for 20 Korean food dishes. Between these two groups the statistics indicated a significant influence with a level p<0.001 for Bulgogi, Bibimbap, Kimchi, Galbi-tang, Galbi-gui, Chicken, Samgyepsal, Doenjang-Jjgae, Dak-galbi, Japchae and Gimbap p<0.01 for Samgye-tang and p<0.05 for Naengmyeon, Kimchi-Jjigae, Dak-galbi, Seolleongtang, Haemul-tang, Hanjeongsik and Tteok-bokki. Jeon and Juk did not show any statistically significant difference. Chinese consumers preferred Korean food for Samgyeopsal, Bulgogi and chicken and less preferred gruel, Hanjeongsik and Kimchi-Jjigae. The highly interested in Korean culture group preferred Samgyeopal, Bulgogi and Chicken, and less preferred Juk, Jeon and Hanjeonsik in that order. This study offers information on the Chinese's preference for different Korean food to any food service enterprises that manage Korean restaurants in China or that sell Korean cuisine and also basic data for differentiated marketing to those entering the Chinese market.
