Recently, various novel numerical models based on Navier-Stokes equation rave been developed for calculating wave motions in the sea with coastal or ocean structures. Among those models, Volume Of Fluid (VOF) method might be the most popular one, and it has been used for numerical simulations of wave motions including complicated phenomena of wave breakings. VOF method, however, needs enormous computation time and large computational storage memories in general, thus it is practically difficult to use VOF method for calculations in the case of random waves because long and stable computation ( e.g. for more than 100 significant wave periods) is required to obtain statistically meaningful results. On the other hand of the wave motion is potential motion, Boundary Element Method (BEM), which is a much faster and more accurate method than VOF method, am be effectively used. The aim of this study is to develop a new efficient model applicable to calculations of wave motion and/or wave-structure interactions under random waves. To achieve this, a strictly combined BEM-VOF model has been developed by making the best use of both methods' merits; VOF method is used in a restricted fluid domain around a structure where complicated phenomena of wave breakings may exist, and BEM is used in the other domains far from the disturbance where the wave motion may be assumed to be potential. The verification of the model was performed with numerical results for Stokes'5th order wave propagation and a random wave propagation.

This research was performed to identify the components and types of comfort foods and to verify gender differences on choosing comfort food in various emotional states. The total of 425 Korean college students participated in this study. The results are as follows. First, most students rated foods that give warmth and relaxation, foods that are reminiscent of happy memories, food that tastes good, were rated as types of comfort foods. On the other hand, external condition and fast food were less likely to be rated as a comfort food. Second, male students reported meat dishes, stew or soup, and alcohol as comfort foods whereas female students reported stew or soup, fruit or vegetable, and meat dishes as comfort foods. Third, the students chose different comfort food in different emotional states. In negative emotions, most students chose alcohol, chocolate, hot (spicy) food, and drinks as a comfort food. But in positive emotions, most students chose chicken as comfort foods. While male students chose alcohol as high ranking comfort food, female students chose various foods as their comfort food. The limitations of this study and suggestions for future studies were discussed.

These purposes are to have a necessity to be educated for the linguistic gifted among many gifted in speedy changeable age, and to find out what differences are of properties between the linguistic gifted children and nongifted children through comparing/analysing to gifted children any nongifted children using performance evaluation on writer's ability. Therefore, it intends to use as a assisting material in order to develop ability and properties of the linguistic gifted children and nongifted children as well. The studying details are 1) to compare/analyze thinking ability between the linguistic gifted children and nongifted children 2) to find out differences of thinking ability for unrealistic reasoning between the linguistic gifted children and nongifted children. The studying subjects had been chosen 3 children as a first grade in 'C' Gifted Academy and 3 children as a first grade in an elementary school from June 3, 1999 to June 12, 1999. The studying instrument was an evaluation of linguistic properties certification(Project Spectrum : Krechevsky,'1994). It had got a frequency calculation, average and standard deviation through the material anylzing with the program SPSSWIN. The conclusions are as belows, First, as a result of performance evaluation on writer's ability to gifted children and nongifted children, the gifted children were outstandingly shown the linguistic ability getting much higher score than nongifted children in respect of vocabulary level, structure of writing, and consistency/logicality of theme. Second, it was shown the gifted children had diffusing thought than nongifted children through the esthetic question and impformation memories with listening to the realistic juvenil story and the unrealistic juvenile story.

This paper attempts to re-read Tennessee William's A Streetcar Named Desire from a non-Aristotelian perspective, particularly focusing on the audience performativity. In Chapter 6 of the Poetics, Aristotle says that tragedy has a final purpose or end (telos) and that is to inspire a catharsis (literally "purification") of pity and fear by means of representation and to give pleasure from experiencing their relief. However, a dramatic theoretician Augusto Boal argues that Aristotelian catharsis is not to get rid of pity and fear through their vehement discharge; rather, the basic function of catharsis is the purging of antisocial elements from the social body and the restoration of order because catharsis occurs when the spectator, terrified by the spectacle of the catastrophe, is purified of his "hamartia" which looks similar to the tragic flaw of the hero in the play. Thus, Boal asserts that Aristotle's coercive system of tragedy manipulates the emotions of the passive spectator. By contrast, in non-Aristotelian aesthetics, tragedy functions not as legitimation for a particular political configuration but as the performance of ethical acts-through which all the participants, including not only the actors but also the audience, communicate more actively about practical problems and actively work in order to make sense of themselves, others, and society. Here, the audience is required to restore and reinforce his/her capacity to think and to act; thus, an unquestioning, passive, indifferent attitude is not allowed. In these contexts, this paper explores how Tennessee William's A Streetcar Named Desire involves the audience in the responsibility for what occurs on the stage, in order to urge the audience's ethical judgements and responsible acts. This paper argues that what this play asks of us is not catharsis, the purging of pity and fear, but empathy toward the other's pain, beyond pity and fear, to carry out our responsibility of sharing in and caring for the other's suffering. That is to say that it will be an ethical way to "re-member" Blanche DuBoi-the iconic Williams victim "dis-membered" by traumatic memories and open wounds and is thus unable to complete her grieving and mourning-as one of us, not as the other. It will be the only way to remember right regarding her tragedy.

The purpose of this study is to analyze the meaning of Joseon school or Korean school (hereafter, Korean school) education in the context of Japanese foreign education through oral history of Korean residents in Japan. I focused on how educational experience of Korean residents who were born and raised in Japan formed through the Korean school education was implemented and applied in Japanese society. Participants were 7 Korean residents in Japan who were educated at Korean school. They all grew up in Kansai region including Osaka Prefecture and Hyogo Prefecture. The oral data was collected three times from September 17, 2014 to February 29, 2016. The oral interviews were conducted two times, two hours per session. As to the analysis of oral data, we first prepared the classification table according to the detailed themes and then cross-checked between the history of Korean residents in Japan as well as related literatures and the memories of the oral interviewees. The results of this study are as follows. The oral interviewees recognized that there was no relation between the development process of foreign education policy in Japan and Korean school education. They said that the education of foreigners in Japan was "consistent with the exclusion of Korean schools." However, unlike the Japanese central government, local governments implemented the policies such as providing subsidies to Korean schools, accepting the graduates of Korean schools in public and private universities, and providing fare discounts for students of Korean schools in local private railways.

This study used Natural Monument water spiders and their habitats as educational contents, so those students could have a scientific literacy and the beautiful memories of Eundaeri's marshes through developing a virtual fieldwork courses (VFC) and observing the ecology of water spiders. In order to develop the program, the 2015 revised national curriculum and its textbooks were analyzed. In accordance with the STEAM model, we developed teaching-learning materials for 7 classes. Students produced 3D panorama virtual fieldwork courses (PVFC) about water spider by team-based cooperative learning, enabling them to emotionally experience the meaning and value of water spiders. A panel of six education experts verified the validity of the program and found it to be fairly valid at 4.24 (CVI = .88) on the 5-point Likert scale. In order to confirm the suitability of the program, students in the middle school science clubs participated in pilot testing camp. Their average classes satisfaction was 4.24 and students were very satisfied with the usefulness of the program, the fresh learning contents, and the suitability of the convergence education class. This study could contribute to convergence education related to ecology and virtual reality for adolescents.

During the Japanese rule, there was an abundance of Japanese writers using colonial Taiwan as the backdrop for their work. However, after Japan's surrender and Taiwan's independence, such writers became nearly invisible. With recent relations between Taiwan and Japan drawing closer, novels and films tracing the modern relationship of the two nations are continually being introduced. Tsushima Yuko's 2008 novel Too Savage and Yoshida Shuichi's 2009 work Road also sprout from the shift in the two countries' and East Asia's historic and political atmosphere. The two books are similar in the sense that they both use countries as the backdrop and recall colonial times. However, the perspectives of the two greatly differ. This paper will compare the meaning behind the narrative strategies that the two authors take in remembering colonial Taiwan and the relationship of the two countries. It will be quite meaningful for Koreans to research the recent works of Japanese writers depicting Taiwan, as Korea also shares a similar modern history. It will also be a good opportunity to ruminate on the entangled modern history of the East Asian region and review relevant literature and culture.

In Korea, historical plays took an epoch-making turn from the previous historical plays in terms of approaches to topic and material and methods of rewriting history in the 1990s. Historical plays became dehistoricized with individual, everyday life, and faction emerging as major codes of historical plays according to mistrust in history and grand narrative as the original and disappearance of trust in the growth and totality of history. A new trend became dominant of presenting fictionality prominent instead of reproduction of history and freely playing with history outside the context. While modern historical plays were subject to the content of history, post-modern historical plays sought after new history writing to tell a new story on history within a framework of fiction. Focusing on some of the trends in post-modern historical plays since the 1990s, which include play with history, daily life-style history writing, and reproduction patterns of colonial modernity, this study examined the goals, representations, and text strategies of new history writing in three historical plays, Generation After Generation(2000) by Park Geunhyung, The Mercenaries(2000) by Park Sujin, and Chosun Detective Hong Yunshik(2007) by Sung Giwoong. In Generation After Generation, the author adopts a plot of starting with the present and tracing back to the past, breaking down the myth of racially homogeneous nation. At the same time, he discloses that the colonial history is not just by the oppressive force of Japan but also by the voluntary cooperation of Korean people. That is, we are also accountable for the colonial history of the nation. The Mercenaries contrasts the independence movement during the colonial period against the modern history developed after Liberation, thus highlighting the still continuing coloniality, namely post-colonial present. The past is presented as the "phantom of history" making its appearance according to the request of the present hoping for salvation. The author politicizes history and grants political wishes to history by summoning the history by personal memories such as fictional diaries and letters with Messiah-like images opposed to the present of collapse and catastrophe. In Chosun Detective Hong Yunshik, the author makes an attempt at the microscopic reproduction of daily life by approaching the 1930s as the modern period when capitalist daily life started to take root. The lists of signs comprising daily life in colonial Gyeongseong are divided between civilization and savagery and between modern and premodern. With the progress of narrative, however, they become mixed together and reversed in the representation system in which the latter overwhelms the former.

As the elderly population is increasing, Alzheimer's disease (AD) has become a global issue and many clinical trials have been conducted to evaluate treatments for AD. As these clinical trials have been conducted and have failed, the development of new theraphies for AD with fewer adverse effects remains a challenge. In this study, we examined the effects of Theracurmin on cognitive decline using 5XFAD mice, an AD mouse model. Theracurmin is more bioavailable form of curcumin, generated with submicron colloidal dispersion. Mice were treated with Theracurmin (100, 300 and 1,000 mg/kg) for 12 weeks and were subjected to the novel object recognition test and the Barnes maze test. Theracurmin-treated mice showed significant amelioration in recognition and spatial memories compared those of the vehicle-treated controls. In addition, the antioxidant activities of Theracurmin were investigated by measuring the superoxide dismutase (SOD) activity, malondialdehyde (MDA) and glutathione (GSH) levels. The increased MDA level and decreased SOD and GSH levels in the vehicle-treated 5XFAD mice were significantly reversed by the administration of Theracurmin. Moreover, we observed that Theracurmin administration elevated the expression levels of synaptic components, including synaptophysin and post synaptic density protein 95, and decreased the expression levels of ionized calcium-binding adapter molecule 1 (Iba-1), a marker of activated microglia. These results suggest that Theracurmin ameliorates cognitive function by increasing the expression of synaptic components and by preventing neuronal cell damage from oxidative stress or from the activation of microglia. Thus, Theracurmin would be useful for treating the cognitive dysfunctions observed in AD.

The purpose of this study was to investigate the Q - method, which is one of the qualitative analysis methods to approach deep and intrinsic meaning about the perception of college students about food in traditional market. Recently, local governments have been developing diverse tourism products aimed at young people in order to revitalize traditional markets. In this study, we classify the perception of food in traditional market by university students, And to suggest strategic implications by using it as basic data for establishing marketing strategy so that young people can visit in the futures. In order to analyze the perception of college students' subjective perception of traditional market food, Factor analysis was used to conduct an exploratory study. To do this, a Q-sort, Program, and Q factor analysis. The results were classified into three types. The first type (N = 21): Memories seeking type, the second type (N = 6): Local culture resource seeking type, the third type(N = 5). Each of these subjective perceptions can be used as a basis for future research. Through the establishment of marketing strategies for each of the three types of classifications, the direction of traditional markets is presented, and a variety of food items that are valuable as local tourism resources are accommodated by accepting university students' to contribute to the revitalization of traditional markets.
