Global climate change is becoming one of the greatest challenges facing humanity. This article proposes a psychological perspective of climate change adaptation. Climate change-related severe adverse weather events may trigger mental health problems, including increased post-traumatic stress disorder (PTSD), depression, anxiety, violence, and even suicide. Forced migration could be considered a coping method for dealing with weather events, but it may also pose a psychological threat. People respond to severe weather events in different ways based on their individual characteristics. Psychological risks from adverse weather events are mediated and moderated by these factors, which are influenced by personal cognition, affect, and motivation. Examinations from a psychological perspective, which have been neglected in the science of climate change thus far, may provide keys to successful adaptation and the prevention of serious psychological problems resulting from the experience of severe weather events. A new prevention strategy has been suggested for coping with climate threats through encouraging attitude change, establishing proactive support systems for vulnerable groups, establishing a PTSD network, and implementing a stress inoculation program.

The present study investigates the hemorheological characteristics of blood flow with applying vibration to a non-aggregating red blood cell suspension. In order to obtain the non-aggregating RBC suspension, blood samples were treated with vibration at a specified condition, which viscosities were taken before and after the treatment, respectively. The viscosity of the blood samples after treatment was higher than before treatment. These treated blood samples were forced to flow through a capillary tube that was vibrated perpendicularly to the direction of the flow. The experimental results showed that vibration caused a reduction of the flow resistance of the non-aggregated blood. The reduction of the flow resistance was strongly dependent on both frequency and amplitude of vibration. These results show potential in treating various diseases in the microcirculation associated with blood cell aggregation.

The migration from rural area to the city has been increased according to the rapid industrialization since 1960's. The decrement of students and teachers forced many elementary' schools in rural area to be abolished. In 1982, the Department of Education started to merge and abolish small schools by the law, and the total number of abolished schools reaches to about 1600 in present. But proper counterplan to the abolished schools has not made sufficiently. This study is to present the methodology for reusing the abolished schools through field survey and analysis of the using type in Chungnam Province.

As the number of immigrants staying in Korea has gradually increased since the mid-1990s, the rate of chronicle migration from certain countries such as China and Vietnam remain high. Registered foreign residents have formed ethnic communities depending on their countries of origin, and the purpose of stay, Korean language literacy, rent, and accessibility have resulted in their self-congregation or forced segregation. This study aims to explore the direction in which immigrants' residential distribution move over time, and whether the ethnic communities show any differences in the level of congregation or segregation. It focuses on identifying the residential distribution of Korean-Chinese, Chinese, and Vietnamese at the city, county, and district level across the country in Korea and examining the congregation and residential changes of three groups over the past decade using centrographic method. Comparing the location as well as the level of residential congregation or dispersion of three groups, which account for the majority of non-professional immigrants in Korea, it will provide a basis for further research on residential congregation or segregation of immigrants in the future.

Regional relocation of population in Korea is required strongly from natural and environmental sides for substantial growth of economy and the rigorous revival national economy against especially internationalization. This paper aimed for analysed the population distribution by regional and special characteristics of the inter-migration and showed the direction of population policy through the model building. Relocation methods of population by region has been examined through the process from the approach method by Haurin's production function to the approach by the utility function. The examination of the development model is done efficiently, how utility these approach models are depends on that scientific and composite plan for population problems against forced policy should be taken precedence.

This article will review the historical background of the development of area studies and the adoption of global studies in Japan. Global studies, which focuses on global issues such as migration, mainly developed in the United States and Europe, but more recently found home in universities in Japan. A characteristic of the development of global studies in Japan is that specialists in area studies have played an important role in institutionally establishing this new discipline. "Japanese area studies" has an affinity with the concepts of global studies contrary to the situation with area studies in the United States. Conventional academic societies based on area studies in Japan, however, have been forced to change as a result of globalization and the establishment of global studies in Japan. I would like to point out that there is some discrepancy between the scholarship boundaries and the actual research and educational program in area studies. I will also discuss how we should reconsider the concept of "area" by tackling global issues.

Intercountry adoption, one type of forced migration, has increased significantly in recent decades. The adoption of Korea-born children by Americans has been the strongest intercountry adoption linkage in the world. The intercountry adoption stream was strongly influenced by intercountry adoption policies, and socio-cultural settings in both South Korea and the United States. Socio-cultural factors in South Korea made local adoption undesirable and helped for abandoned children to be adopted by Americans, while socio-cultural factors in the United States had reduced the number of locally available infants for adoption, and increased the demand for infants from abroad. Distribution of Korea-born adoptees shows concentration in the Pacific Northwest, Upper Midwest and Northeast areas which have not attracted Korean immigrants so generally. The trend of concentration shows some increased importances in the outlying states in the northern United States. The location and activity of agencies shaped the spatial distribution of Korea-born adoptees in the United States.

Korean adoptee narratives have proliferated over the last ten years as adopted Koreans have begun to represent their own experiences of violent dislocation, displacement and loss in various forms of literary and artistic works, including poems, autobiographical works, novels, documentaries and films. These narratives by Korean adoptees have intervened in the current diaspora discourse to question further the traditional categories of race, ethnicity, culture and nation by representing the unique experiences of the forced and involuntary migration of adopted Koreans. For a long time, the adoption discourse has been mostly constructed from the perspectives of adoptive parents. Therefore the voice of adoptees as well as that of the birth mothers have not been properly heard or represented in adoption discourse. According to Hosu Kim, the U. S. adoption discourse, feeling pressured to deal with the stigma of the commodification of children, changed from viewing the adoptees as children who had been rescued from poverty and abandonment to considering them as a gift from the birth mothers. With the emergence of the gift rhetoric in transnational adoption, the birth mothers erased from adoption discourse have begun to be acknowledged as one of the central characters in the adoption triad. If Korean adoptees are the "the ghostly children of Korean history," the birth mothers are their "ghostly doubles" who "bear the mark of a repressed national trauma." Somebody's Daughter represents the female experiences of becoming an adopted child and of being a birth mother. In particular, the novel makes a birth mother, the forgotten presence in adoptee narratives, into a central figure in the triangular relationship created by international adoption. The novel historicizes the experiences of a Korean adoptee growing up in America as well as those of a mother who had suffered silently from feelings of unbearable loss, guilt, grief and from unforgettable memories. In addition, narrating the birth mother's story is a way to give humanity back to these forgotten women in Korean adoption history. Revisiting the site of loss both for a mother and a daughter through the novel is an act of collective mourning. The narratives about and by Korean adoptees force Korean intellectuals to reflect seriously upon Korean society and its underlying ideology which prevents a woman from mothering her own baby, and to take an ethical and political stand on this current social and political issue.

This study analyzes the impact on geomorphic changes downstream due to alternate bars developed weir upstream through laboratory experiments. The disturbance, such as a spur in the side wall, of the flow at the inlet of the channel triggers the development of alternate bar upstream at the beginning of the experiment, and gradually moved downstream with keeping their shapes over time. The bed in the downstream of weir in the mid of channel scoured due to the scarcity of sediment inflow because weir upstream traps it. Moreover, bar migration speed decreases as the bars approaches to the weir with time. However, as time increases, the alternate bars upstream migrate over the weir, and sediment in the eroded bed of the weir downstream are deposited. The phase of the bar upstream changes oppositely after passing through the weir. The phase of the bar downstream changes rapidly as the shape of alternate bar is clear upstream, which is affected by the strong disturbance. The phase of bar changes, and the bar migration speed decreases gradually with time, and finally stopped due to forcing effects on the bar by the disturbance. The faster the reaction of alternate bar with a long spur, the larger the bar height formed downstream and the shorter the bar length. This means that the larger the forcing effect of bar, the more it affects the bar migration. In addition, although the size of the alternate bar increases over time, the bar doesn't migrate downstream and a forced bar is generated.

Glucose regulated protein 78 (GRP78) is frequently highly expressed in tumor cells, contributing to the acquisition of several phenotypic cancer hallmarks. GRP78 expression is also positively correlated with tumor metastasis, and promotes hepatocellular carcinoma cell invasion via increasing cell motility, however, other mechanisms involving the prometastatic roles of GRP78 remain to be elucidated. Here we report that forced GRP78 expression promotes colon cancer cell migration and invasion through upregulating MMP-2, MMP-9 and especially uPA production. These effects of GRP78 are mediated by enhancing the activation of ${\beta}$-catenin signaling. Interestingly, we identify that GRP78 interacts with uPA both in the cells and in the culture medium, suggesting that GRP78 protein is likely to directly facilitate uPA secretion via protein-protein interaction. Taken together, our findings demonstrate for the first time that besides stimulation of cell motility, GRP78 can act by increasing proteases production to promote tumor cell invasion.
