Korean society has significantly changed with the onset of a dramatic economic crisis in 1998. From 2000, however, the Korean economy has recovered and currently Korea is enjoying a similar standard of living and economic growth as the pre-1998 levels. This study is a follow-up analysis, comparing the results examining the success attribution of Korean students and adults in 2001 with the results obtained before the economic crisis in 1997. Using the indigenous psychological approach, this study compares the similarities and differences in Korean students and adults' attribution of their personal success before and after the economic crisis. A total of 988 participants, consisting of 481 primary, junior high, senior high and university students and 507 adults (236 fathers and 271 mothers of the students) completed the questionnaire developed by Kim and Park (1998). The results indicate that students perceived their academic achievement and adults perceived successful family life as their most proud achievement. Successful family life included items such as academic success of children, healthy development of their children, and harmonious family life. The person who provided the most significant support for students were parents and for adults, it was their spouse. For students, the importance of friends' social support increased during the high school years. In terms of type of social support, emotional support was reported to be the most important for both students and adults. As for the reason for their success, majority of students and men reported self-regulation and for women, supportive family environment was reported as being the most important. Comparing 2001 results with the 1997 results, the importance of family increased after the economic crisis. Even with the dramatic economic crisis, however, some of the underlying pattern remain strong (such as importance of academic achievement for students, family life for adults, the importance of social support, especially emotional social support from family members, and believing that self-regulation would lead to success). The similar pattern of results obtain before and after the economic crisis indicate that the above results reflect a fundamental values and belief system deeply imbedded in Korean mentality.

Korean society has begun to transition toward a multicultural society, and the rate of change is increasing. If so, is our society ready to meet this change of society? It is true that Korean society has been dominated by the paradigm of 'monoethnicity', and traditionally has been regarded as a virtue to maintain this view. However, it is worth noting that isolated single cultures have historically met a disastrous end. On the contrary, people who have adapted their culture and style have enjoyed prosperity. Korean society has hovered between embracing and rejecting the flow of change, and has finally accepted them to choose the way to go on a multicultural society living together. However, it seems that the changes in policy have not kept pace with recent changes in society. Despite the fact that the most efficient way to change perception is to establish and implement appropriate educational policies promoting multiculturalism, most education in Korean society has focused on the closed form of education, for the influx people, not having been made proper education for most of Korean people who should actually accept them and get along with them. Therefore, they have been striving for an assimilated viewpoint that simply get it transformed into Koreanized, not understanding and accepting them as they are. However, this type of education cannot lead a Korean multicultural society in the right direction. We objectively examined the reality of Korean society facing this crisis and presented policy changes regarding multicultural education through examining the case of France, which experienced a similar crisis prior.We are going to present the direction of change in multicultural education through the case of France which has experienced similar crisis before us by examining the reality of Korean society facing the crisis like this.

From 1983, until June, 1990, 10 patients with various type of truncus arteriosus underwent total surgical correction including Rastelli procedure at Seoul National University Hospital. The age at operation ranged from 1 month to 9 years [mean 2.1 years]. Six patients had truncus type I, 3 patients had truncus type II, and one patients had truncus type IIIc. Right ventricular pulmonary artery continuity was established with a porcine valved conduit in 6 patients, mechanical valved conduit in 1 patient, and bovine pericardial conduit in 3 patients. The postoperative right ventricular /left ventricular pressure ratio ranged from 0.4 to 0.71 [mean 0.51${\pm}$0.14]. The lung histology revealed grade II pulmonary obstructive disease even at 4 month of age. Five patients were dead in hospital [50%], and they were less than 2 year of age. One patient, who had severs congestive heart failure preoperatively, died of low output syndrome and the other died of low output syndrome with postoperative bleeding. There were three death, because of a pulmonary hypertensive crisis that might have been prevented. Two of the five survivors had conduit failure over a mean follow up of 42 months [range 1 to 78 months]. Obstructed conduit was removed and a new conduit constructed using the conduit bed as the posterior wall and the patch of bovine pericardium and Dacron as patch the roof of the conduit. One patient died of acute cardiac failure during the operation. Although results in infants less than 2 years old have not been good, current improvement of intra-and postoperative care suggested that prompt repair is indicated for infants with truncus arteriosus.

The world is facing a serious energy problem which destroying the environment. In addition, fossil fuel such as oil and coal that caused global warming and the environmental problems due to acid rain had been gradually exhausted. To solve this problem that has crisis of energy, it is necessary time and effort for research and development of renewable energy in the future. As alternative energy, small hydropower generation which has output of less or equal to 100kW is attracting considerable attention. This is because of its small, simple, renewable, and large amount of energy resources. By using a small hydropower generator of which main concept is based on using the different water pressure levels in pipe lines, energy which was initially wasted by use reducing of a valve at the end of the pipeline, is collected by turbine in the small hydropower generator. In this study, we investigated the influence of the number of runner vanes on the characteristics of tubular-type hydroturbine.

The 14 cities and guns within Gangwon-do were divided into three regions (urban-rural-integrated type, urban type, and ruralcoastal type), and local voluntary disaster prevention organizations in those regions were surveyed as sample groups. As a result, the urban-rural-integrated type and the urban type were found to be lower than the rural-coastal type in all domains including recognition of disaster crisis, evacuation guidance, preparation of voluntary evacuation, maintenance of disaster prevention system, surveillance & guard, and information delivery. In particular, three types had higher information delivery but considerably lower preparation of voluntary evacuation. As for information delivery, foundations for rapid delivery of disaster information due to establishment and extension of systems for forecasting and warning of local governments were prepared, but as for preparation of voluntary evacuation, it is needed not only to perform consistent training and promotion for preparation for disasters for residents to accurately understand status of disasters but to take measures to secure safe places for evacuation beforehand.

Volatility forecasting in financial markets is an important issue because it is directly related to the profit of return. The volatility is generally modeled as time-varying conditional heteroskedasticity. A generalized autoregressive conditional heteroskedastic (GARCH) model is often used for modeling; however, it is not suitable to reflect structural changes (such as a financial crisis or debt crisis) into the volatility. As a remedy, we introduce the Markov regime switching GARCH (MRS-GARCH) model. For the empirical example, we analyze and forecast the volatility of the daily Korea Composite Stock Price Index (KOSPI) data from January 4, 2000 to October 30, 2014. The result shows that the regime of low volatility persists with a leverage effect. We also observe that the performance of MRS-GARCH is superior to other GARCH models for in-sample fitting; in addition, it is also superior to other models for long-term forecasting in out-of-sample fitting. The MRS-GARCH model can be a good alternative to GARCH-type models because it can reflect financial market structural changes into modeling and volatility forecasting.

In the present study, effects of tree-stream turbulence and surface trip wire on the flow past a sphere at $Re\;=\;0.4\;{\times}\;10^5\;{\sim}\;2.8\;{\times}\;10^5$ are investigated through wind tunnel experiments. Various types of grids are installed upstream of the sphere in order to change the tree-stream turbulence intensity. In the case of surface trip wire, 0.5mm and 2mm trip wires are attached from $20^{\circ}\;{\sim}\;90^{\circ}$ at $10^{\circ}$ interval along the streamwise direction. To investigate the flow around a sphere, drag measurement using a load cell, surface-pressure measurement, surface visualization using oil-flow pattern and near-wall velocity measurement using an I-type hot-wire probe are conducted. In the variation of free-stream turbulence, the critical Reynolds number decreases and drag crisis occurs earlier with increasing turbulence intensity. With increasing Reynolds number, the laminar separation point moves downstream, but the reattachment point after laminar separation and the main separation point are fixed, resulting in constant drag coefficient at each free-stream turbulence intensity. At the supercritical regime, as Reynolds number is further increased, the separation bubble is regressed but the reattachment and the main separation points are fixed. In the case of surface trip wire directly disturbing the boundary layer flow, the critical Reynolds number decreases further with trip wire located more downstream. However, the drag coefficient after drag crisis remains constant irrespective of the trip location.

The recent economic crisis started at the end of 1997 has brought about changes in labor market practices. One of them is rapid increase in the ratio of workers with alternative employment arrangement, so-called contingent workers. This type of arrangement, unlike traditional employment arrangement, makes employers properly adjust employment to business cycles and it also makes it possible for employees to solve time and spatial constraints related to labor supply. However, recent experience has revealed its negative characteristics such as lower wage rate, deficient fringe benefits, insufficient job security. Using the data from the first and the second wave of the Korea Labor and Income Panel Survey, this study focuses on change in the tendency of being contingent workers and decomposition of the wage differentials among regular and contingent workers by estimating the switching regression model. Results show that the recent crisis significantly contributed to probabilities of being contingent workers, especially for women, the young, the older, and the lowly educated. Decomposition shows that one quarter or one third of 35% of wage differentials are due to the price effect that the same productive characteristics are differently paid by the types of employment arrangements.

Game is the latest type of Gesamtkunstwerk encompassing humanistic and engineering creativity. Nevertheless, Korea's game industry faces a crisis. The purpose of this study is to consider positive emotion-inducing effects as a way to deal with it. Among others, storytelling of , one of the most representative MMORPG games in the world, was selected for the study on various positive emotion-inducing effects. In the story of , the view of the world, characters and incidents are vital to the game and the study is focused on their emotion-inducing effects among the users based on actual examples. As a result, it was confirmed that the positive emotion-inducing storytelling would provide a possibility to reduce negative sentiment towards games, address crisis Korea's game industry faces, and interact with gamers in a positive direction.

In Woman Watches over the World, Linda Hogan explores the broken identity of herself and her family, the issue of the poverty and the identity crisis, the alcoholism, prevalent in the Native American community and their silenced history. Previous studies have claimed that her memoir contributes to the restoration of Native American identity and history by accusing the violence of white culture, and seeks to recognize a dialogue between native culture and white mainstream culture as well. However they seem to overlook the complicated relations among story, identity, body and nature, to which Hogan as a multi-binded storyteller resorts as a way to break the silence of herself and her tribe for healing. Her own story, as a way to break the silence, becomes the formative drive to reveal the silenced history of her own tribe to lead the young generation to the future. She also understands the formative function of the story, which becomes the vehicle for embodying and connecting themselves to nature. To her, healing lies in the restoration of sympathetic relationship with nature. History, as a type of story, can be made up or mistold just like a story. There may be a blind spot where one can not assess what is true. In spite of the vision of the parallel worlds of the two cultures she presents, there seems to be no immediate solution to the discrimination against the Native American, poverty, identity crisis, and environmental problems which the Native American community faces. However, it can be said that her memoir serves as a rudder by presenting a direction to not only the Native American but also to readers in other cultures in its quest for practical possibilities for the future.
