Although there are numerous studies that address the problem of optimal machine grouping and part family classification for cellular manufacturing, little research has been reported that studies the conditions where cellular manufacturing is appropriate. This paper, in order to evaluate and compare the job shop with the GT cellular shop, the performance of those shops were simulated by using SIMAN. We tested the effect of independent variables including changes of product demands, intercell flow level, group setup time, processing time variability, variety of material handling systems, and job properties (ratio of processing time and material handling time). And also performance measures (dependent variables), such as machine utilization, mean flow time, average waiting time, and throughput rate, are discussed. Job shop model and GT cellular shop written in SIMAN simulation language were used in this study. These systems have sixteen machines which are aggregated as five machine stations using the macro feature of SIMAN. The results of this research help to better understand the effect of production factors on the performance of cellular manufacturing systems and to identify some of the necessary conditions required to make these systems perform better than traditional job shops. Therefore, this research represents one more step towards the characterization of shops which may benefit from cellular manufacturing.

Despite intensive therapy, a large proportion of stroke survivors are left with significant disabilities. To improve the disable condition, a major component of stroke management is aimed at facilitating functional independence and community reintegration. There are many evidences that community-based rehabilitation after stroke is most effective when provided by a well-organized multidisciplinary team. Key to the implementation of community-based rehabilitation(CBR) is that the disabled person, their family and their community decide on what the priorities of the service should be. The stroke patients in the community need a wide range of services, including the traditional rehabilitation services of physiotherapy, occupational therapy, speech therapy, social workers, orthotists, nurses and so on. The purpose of this research was to investigate necessity and methods of community-based rehabilitation system in Korea.

The purpose of this paper is to examine and analyse the features of plan type and space composition of the Siheyuan(courtyard house) which is one of the most remarkable types of the traditional dwellings in China. With the passage of time this house developed into one of the chinese house style. The technique of Siheyuan's spatial composition goes so far back in the New Stone Age. The relics of this are the colony layout, the system of four sides, the layout type of a palace, the picture of lacquered ware, the pictured brick, the earthenware of house type, the cave painting, the paintings of painters and others. The fundamental spatial conception of it arranges one or more courtyards to compose, sometimes in a very complex way, a general walled compound. The main longitudinal axis is mainly north-south, but the chief buildings, or halls are always placed transversely to it. These rectangular buildings mayor may not connect, by means of open galleries variously planned, with rows of smaller buildings flanking the courtyards on both sides. On this system, enlargement is never carried out by adding to height, but by continual duplication of existing units, and growth in breadth or preferably depth. The need for family security is thought to have led to the development of this rectangular houses with walls mainly blank on the outside, defensible entrances, and public service facilities in the center of the houses.

The significance of Boseong Tea Agriculture System lies in its harmonious coexistence with the surrounding environment, producing high quality teas and maintaining its biodiversity. Boseong Tea Agriculture System has been inscribed as Korea's Important Agricultural Heritage System (KIAHS) in 2018, but the Aging Society of tea farmers is threatening the conservation and succession of tea farming of the region. The study suggests designation of Boseong Tea Agriculture System as one of Globally Important Agricultural Heritage System (GIAHS), objecting conservation and succession of Boseong Tea Agriculture System. The study has reviewed GIAHS, KIAHS, Boseong Tea Agriculture System and surveyed tea farmers of Boseong for 3 months from March to May, 2020. The survey method includes face to face interview, phone interview (ones couldn't be reached for face to face interview) and in-depth interview of community leaders and experts, verifying the Aging Society status in Boseong tea agricultural industry. The survey result includes the following. Average age of Boseong tea farmers is 69.4 years old. Family tea-farming over two generation is 36% (54 household), and 79.4% (119 household) depends on 90% of income from tea production. The in-depth interview shows the aging tea farming society is most serious concern of tea farmers and GIAHS designation will support reliability and recognition of Boseong tea, helping conservation and succession of Boseong Tea Agriculture System. GIAHS designation will enhance and share the value of Boseong Tea Agriculture worldwide and be able to inherit the heritage for our future generation.

Because of the oocIear family due to the rapid industrialization and the growth of husband and wife bah working, the base of the tradition that the parents, all of the famly or the hamet oonmunity bring up the infants together in the important time to the infarts has been collapsed in Korea. Because working mothers camot bring up their children by themselves they got stressed and housewives do not have the oonfidence in rearing their infants and the fathers are isolated from home and the chikten instead of being exempted from the responsibility of rearing children. Therefore the common and comprehensive rearing system should be made for solving the child-rearing problem. For solving these problems and for the desirable infant-rearing and education, the joint irlart rearing, whidl compensates for the life, education and furthermore the sdlool edJcation through the volur1ary participation, has been prepared altematively. Compared to the traditional rearing system, joint infant-rearing is not only operated by the residents with the dues paid by the union members but also makes children experience the life force of natu"e in themselves. So the preparation of the standard of the suitable environment design for the joint infant-rearing is required which is diffrent from the traditional standard of the environmertal facilities for the traditional rearing system. The concept of joint infant-rearing was defind in this study through the reference and the ooncept of infant edJcation which is in operation suocessfully in Italy and Sweden in order to understand how the ooncept of infant education has changed as the ages have dlanged. And the basic principals for the formation of physical envirorvnert and the spare design and the envirorYnertal oondition for the practical environmental design was also studied through the reference. And after study about the concept. figure and physical environmental suggestion, the concept, standard and element of joint infant-rearing environment design was suggested. And as the final conclusion, the design requirement of the envirorvnertal design for the joint infant-rearing was suggested.

During the Japanese colonial period, the palaces of Joseon were damaged in many parts. Changgyeonggung Palace is the most demolished palace with the establishment of a zoo, botanical garden, and museum. During the Japanese colonial period, the palaces of Joseon were damaged in many parts. This study examined the construction process of Jangseogak(Yi Royal-Family Museum), located right next to the Jagyeongjeon site, which was considered the most important space in the Changgyeonggung residential area of royal family zone, through historical materials and field research. Built in 1911, Jangseogak is located at a location overlooking the entire Changgyeonggung Palace and overlooking the Gyeongseong Shrine of Namsan in the distance. Changes in the surrounding space during the construction of Jangseogak can be summarized as follows. First, in the early 1910s, the topography of the garden behind Jagyeongjeon and part of the Janggo were damaged to create the site of Jangseogak. The front yard was built in the front of Jangseogak, and a stone pillar was installed, and a staircase was installed to the south. In the process, the original stone system at the rear of Yanghwadang was destroyed, and it is presumed that Jeong Iljae and other buildings were demolished. Second, in the 1920s, many pavilions were demolished and the zoo and botanical gardens and museums were completed through leveling. After the Jangseogak was completed, the circulation of the Naejeon and surrounding areas was also changed. Cherry trees and peonies were planted in the flower garden around the front yard of Jangseogak and the stairs, and a Japanese-style garden was created between Yanghwadang and Jibbokheon. Third, in the 1930s, the circulation around Jangseogak was completed in its present form, and the museum, Jangseogak, Zoological and Botanical Gardens, and Changgyeonggung, which became a cherry tree garden, were transformed into a Japanese-style cultural park. After that, the surrounding space did not change much until it was demolished. The restoration of the present palace is a long-term, national project of the Cultural Heritage Administration. The results of this study will provide important data for the restoration plan of Changgyeonggung Palace in the future, and it is expected that it will provide additional information to related researchers in the future.

The Korean Population Control Program has been implementing under the jurisdiction of the Ministry of Health and Social Affairs through an existing network of health centers. This arrangement was successful in bringing population growth down to targeted level by the end of the Fourth Five Year Economic Planning, 1981. It is expected, however, that future goal will be harder to reach due to difficulty of reducing traditional family size norms further and to the projected increasing the number of eligible couples as the past Korean war baby boom generation enters the reproductive activity in the next few years. The recognition of the need for modification of population policy is increasing. The 1980 census shows that the total number of population reached approximately 38.5 million with 1.57 per cent of the growth rate. It was projected that the size of Korean Population will reach around 42 million and 51 million in 1986 and 2000 respectively. Furthermore, there is some argument as to whether decline in the birth rate in Korea is too slow to meet government target. Hence, a new development of population policy and greatly increased amount of effort will be needed in order to achieve Zero Population Growth Rate before the year 2050. The development of future national population policy and its related area are recommended as follow: 1. It is highly recommended that the population planning law governing both vital events of birth and death and population migration should be legislated. 2. The National Population Policy Council, Chaired by Deputy Prime Minister should be activated to implement and coordinate population program within ministries. 3. Responsible organization of population and family planning program should be established as a Bureau unit at central government level. 4. For the improvement of national vital registration, an existing system should be studied and developed.

This qualitative research was designed to explore the use of housing among Korean Chinese people in Harbin, China. Focusing on the use which based on the epistemology of housing adjustment, this was particularly designed to examine its cultural assimilation and acculturation on the way of life course, it employed the in-depth interview on the oral history of 5 interviewees in their 60s and 70s, individualized interviews were conducted from May 28 to 31 in 2010. Key findings were summarized as follows; 1. The free market reform in China resulted in privatization that allowed respondents to become homeowners, and the ownership was viewed as part of family asset centered upon a sense of solidarity. 2. Although homeowners in multi-story houses were responsible to decorate interior spaces, the common features in using interior spaces were found: entrance had no thresholds; kitchen was small, lack of storage cabinets, tile-flooring; washers were installed inside bathroom; and newly built apartment didn't have proper space to store Korean fermented foods. It was observed that housing adaptation outweighed housing adjustment. Those who used to live in Chinese houses with indoor-wearing-shoes or Russian houses with indoor-wearing-slippers were receptive to the use of dining table and bed, and the community heating system discouraged the use of individual electric water heater because of high electricity cost. 3. In daily life, eating habit wasn't much changed to the Chinese style, meals were shared, dish sterilizer was popular, and Kimchi fridge wasn't used. Because of the influence of the Chinese culture, such Korean traditions as ancestral rites and bedroom allocation tradition faded away, but traditional family values remained unchanged. In conclusion, Korean Chinese people experience normative housing deficits and adaptation selectively incurred. It's implied that residential design meets the needs resulting from the dual culture in terms of cultural assimilation and acculturation.

Korean Red Ginseng extract (KRGE) is a traditional herbal medicine utilized to prevent endothelium dysfunction in the cardiovascular system; however, its underlying mechanism has not been clearly elucidated. We here examined the pharmacological effect and molecular mechanism of KRGE on apoptosis of human umbilical vein endothelial cells (HUVECs) in a serum-deprived apoptosis model. KRGE protected HUVECs from serum-deprived apoptosis by inhibiting mitochondrial cytochrome c release and caspase-9/-3 activation. This protective effect was significantly higher than that of American ginseng extract. KRGE treatment increased antiapoptotic Bcl-2 and Bcl-$X_L$ protein expression and Akt-dependent Bad phosphorylation. Moreover, KRGE prevented serum deprivation-induced subcellular redistribution of these proteins between the mitochondrion and the cytosol, resulting in suppression of mitochondrial cytochrome c release. In addition, KRGE increased nitric oxide (NO) production via Akt-dependent activation of endothelial NO synthase (eNOS), as well as inhibited caspase-9/-3 activities. These increases were reversed by co-treatment of cells with inhibitors of eNOS and phosphoinositide 3-kinase (PI3K) and pre-incubation of cell lysates in dithiothreitol, indicating KRGE induces NO-mediated caspase modification. Indeed, KRGE inhibited caspase-3 activity via S-nitrosylation. These findings suggest that KRGE prevents serum deprivation-induced HUVEC apoptosis via increased Bcl-2 and Bcl-$X_L$ protein expression, PI3K/Akt-dependent Bad phosphorylation, and eNOS/NO-mediated S-nitrosylation of caspases. The cytoprotective property of KRGE may be valuable for developing new pharmaceutical means that limit endothelial cell death induced during the pathogenesis of vascular diseases.

This study analysed the narrative strategies in TV drama utilized in order to support the recent feminism movements. The analysis revealed that this TV drama breaks away from the clichéd patriarchal drama series. It portrays the main characters are not the sons but the two daughters-in-law, and represents the women challenging the order of the patriarchy, and resolving the issues. In this drama, men's power was removed and female agents were held up to ridicule. In addition, it eradicates the traditional female conflict structures and creates a strong bond between the females. With this storyline, TV series concludes with two achievements. One, the stepmother and the mother co-parent the child instead of the father, suggests that a non-blood related matriarchal family is possible. Two, the heir to the chaebol family, which is traditionally a patrilineal structure, is not the oldest son or the immoral son, but the lesbian daughter-in-law, overturning the idea of heteronormativity that is dominant in the patriarchal system.
