There are 3,931,822 elderly who receives long-term care at home and 1,704,469 elderly who stay at long-term care facilities in those of 34,610,000 of +65 years old population in Japan; thus, the elderly people who need home care are 2.3 times more than facilities (2016).In the near future, the number of elderly people with a degree of daily life independence and dementia category II or more will increase to 4.7 million (12.8% of the elderly population). Therefore, the use of home-care robots is essential for the disaster evacuation of the overwhelming majority of those elderly who need home care and for of vitals checks to keep family, caregivers, and medical professionals informed to reduce the risk in chronic health conditions in welfare evacuation centers. This also helps to care for the caregivers who are caring for the elderly, and the introduction of home-robots to evacuation centers should receive prompt attention from our care-friendly society.

Gloria Naylor's second novel Linden Hills (1985) explores the issues of self-exploration, empowerment, history, and memory by delineating the communal and familial tragedies and the distortion of values prevalent in a prosperous African-American urban community called Linden Hills. Drawing upon the Freud's concept of "primal scene" and "family romance," this paper aims to focus upon the Nedeed family, the founder of Linden Hills, and investigate the compelling traumatogenic force within the family, which is inseparably intertwined with the inversion of values and moral corruption permeating the entire community. The "primal crime" committed by the Nedeed ancestors serves to preserve and perpetuate a tyrannical rule by ruthless patriarchs who reign by underhanded strategies of purposefully neglecting and abusing others, including their own wives. The imprisonment, by Luther Nedeed, of his wife Willa in the family morgue epitomizes the long legacy running in the family-the oppression and burial of the pre-Oedipal, maternal history. Willa's accidental encounter, at the nadir of the family estate and her personal despair, with the faded records of the forgotten and abused Nedeed women exposes the violence-ridden ground of the family's primal scene and the absurdity of family romance the Nedeeds pursued. As the several lines of poem composed by Willie, Willa's male double, show, the hidden, forgotten history of the Nedeed women, in a sense, is the real, which cannot be assimilated to the social symbolic governed by the inhumane patriarchy of the Nedeed family and the success-oriented Linden Hills society. By portraying a catastrophic downfall of the Nedeed family and the futile outcome of its family romance, the ending of Linden Hills conveys implicitly that the contingent symbolic order and its oppressive control, however solid and invincible they may seem, can be toppled down by the real, its nameless forgotten Other.

Under the inhumane oppression of imperialism, the Third World's political violence has been often represented as an immediate and explosive one with an instant, concentrated visibility. Yet the ecological and psychological exploitation of the Third-World countries by empires, as Rob Nixon insists, shows the relative invisibility of slow violence. This paper is to reveal this slow violence of the marginalized areas symbolized as the lowland. Although Arne Naess' deep ecology promotes the inherent worth of living beings regardless of their instrumental utility to human needs. this paper deals with three postcolonial ecological textbooks which criticize the white-centered deep ecology: Amitav Ghosh's The Glass Palace, Jhumpa Lahiri's The Lowland, and Barbara Kingsolver's The Poisonwood Bible. Through postcolonial critical study, this paper finds out that all these three works have some themes in common. First, these postcolonial works assume a shape of family saga which is parallel to the slow violence of ecological and psychological plundering of empires in the postcolonial countries. Second, like the mangroves which have a tenacious hold on life, these postcolonial people rather overcome the heterogenic challenge with the sturdy and tough mind than defeated. Third, the native people's ethics of earth functions as the stronghold for their respectable lifestyle in their indigenous historicity. Finally, as a big fat brother, the Americanized globalization or neoliberalism is warned as the neocolonialism which is often shown as the disguised pattern of greenwashing. Namely, the people's self-enhancement is always prior to the imperialistic development or neoliberalism in the postcolonial ecological texts which sharply contrast the native's life consciousness and the empire's development theory.

Out of twenty common protein amino acids, there are many kinds of non protein amino acids (NPAAs) that exist as secondary metabolites and exert ecological functions in plants. Mimosine (Mim), one of those NPAAs derived from L. leucocephala acts as an iron chelator and reversely block mammalian cell cycle at G1/S phases. Cysteine (Cys) is decisive for protein and glutathione that acts as an indispensable sulfur grantor for methionine and many other sulfur-containing secondary products. Cys biosynthesis includes consecutive two steps using two enzymes-serine acetyl transferase (SAT) and O-acetylserine (thiol)lyase (OASTL) and appeared in plant cytosol, chloroplast, and mitochondria. In the first step, the acetylation of the ${\beta}$-hydroxyl of L-serine by acetyl-CoA in the existence of SAT and finally, OASTL triggers ${\alpha}$, ${\beta}$-elimination of acetate from OAS and bind $H_2S$ to catalyze the synthesis of Cys. Mimosine synthase, one of the isozymes of the OASTLs, is able to synthesize Mim with 3-hydroxy-4-pyridone (3H4P) instead of $H_2S$ for Cys in the last step. Thus, the aim of this study was to clone and characterize the cytosolic (Cy) OASTL gene from L. leucocephala, express the recombinant OASTL in Escherichia coli, purify it, do enzyme kinetic analysis, perform docking dynamics simulation analysis between the receptor and the ligands and compare its performance between Cys and Mim synthesis. Cy-OASTL was obtained through both directional degenerate primers corresponding to conserved amino acid region among plant Cys synthase family and the purified protein was 34.3KDa. After cleaving the GST-tag, Cy-OASTL was observed to form mimosine with 3H4P and OAS. The optimum Cys and Mim reaction pH and temperature were 7.5 and $40^{\circ}C$, and 8.0 and $35^{\circ}C$ respectively. Michaelis constant (Km) values of OAS from Cys were higher than the OAS from Mim. Inter fragment interaction energy (IFIE) of substrate OAS-Cy-OASTL complex model showed that Lys, Thr81, Thr77 and Gln150 demonstrated higher attraction force for Cys but 3H4P-mimosine synthase-OAS intermediate complex showed that Gly230, Tyr227, Ala231, Gly228 and Gly232 might provide higher attraction energy for the Mim. It may be concluded that Cy-OASTL demonstrates a dual role in biosynthesis both Cys and Mim and extending the knowledge on the biochemical regulatory mechanism of mimosine and cysteine.

본 논문은 다인종, 다민족, 다문화적 미국사회에서, 한인, 백인, 흑인의 관계로 형성된 인종 삼각구도의 양상과 의미를 1992년 로스앤젤레스 인종 폭동을 중심으로 분석한다. 한국계 미국 이민 2세대 작가 스텝 차(Steph Cha)의 『너의 집이 대가를 치를 것이다』 (Your House Will Pay, 2019)를 그 분석의 대상으로 하여, 인종 삼각구도와 연관된 인종서열 관념, 인종적 상투형, 인종간 분리, 역사적 주변화, 문화적 편견의 쟁점을 살펴본다. 대도시 공간에서의 인종폭력에 얽힌 한인가족과 흑인가족의 좌절과 분노, 갈등과 증오, 트라우마와 죄의식을 통해 백인주도 사회의 다인종 간 상호관계를 탐색한다. 특히 LA 인종 폭동의 도화선이 된 한인 이민 상점주와 흑인 토착시민 소비자 배후에 자리잡은 이민자와 토착시민의 갈등 구조, 이민 소자본 자영업 공간의 특성, 이민경제적 양상을 중심으로, 대도시 폭력의 쟁점을 탐색한다. 흑백관계, 한백관계, 한흑관계로 이어지는 인종 삼각구도를 읽어내는 과정을 통해, 미국의 국가적 자원이자 역사적 갈등의 원천이 되는 인종 쟁점의 사회경제적 매트릭스에 대한 문화적 문식성을 강화하고, 초인종적, 초민족적, 초문화적 공감과 생명 공동체로서의 미래지향적 시민의식의 확장을 모색한다.
