From 1990s to the present, in China, residential communities has developed rapidly in terms of government policies and living environments. With economic development, dwelling commercialization and socialization gradually reshaped the housing distribution system and local government management in Chinese urban area. After this process, dwellings were endowed with commodity attributes, which were planned and designed depending on residents' requirements of life. During the 30 years of social transformation, Chinese citizens' lifestyle also had huge changes. In this period, the forms of residential area improved constantly to keep pace with social development. This study aims to research the features of contemporary communities and survey citizens' lifestyle changes to find the reasons of the evolution of communities. Moreover, in this paper, there is a clear explanation of the reasons why gated communities are popular in Chinese urban area. In addition, comprehensive data analysis is derived from a questionnaire administered in Shanghai, China. In this part, the questionnaire surveys what factors about lifestyle influence the transformation of living environments and residential buildings. The results of survey show that residents have housing preferences dependent on their lifestyles, and their daily needs related with environmental features.

This study investigates the differences among residental areas in the health, standard of living, and social relationships of female elderly living alone. The total of 501 subjects(185 from rural areas, 159 from fishing communities, 77 from the islands, and 80 from urban areas) were questioned from May to July, 2006. The research area was confined to Chungcheong Province. The female elderly living alone of this study were an average of seventy-three years old, had a low cost of living, and received little formal school education. Over sixty percent(60.3) of them lived on less than thirty dollars a month which was the recognized Korean poverty level in 2006. The female elderly living alone were evaluated as being in good health, but they themselves perceived their health as being poor. Observed by residential areas, the subjects in urban areas were lower in ADL, and both the urban dwellers and the islanders appeared to be higher in their satisfaction with medical services as compared to those in rural areas and fishing communities. The fishing villagers showed the lowest standard of living for female elderly living alone. The analysis of social relationships as seen in the different residental areas revealed that the female elderly living alone g in urban areas tended to be receiving social supports rather than providing for others, and subjects living in fishing areas and the islands proved to be relatively higher in the exchange of social supports. In relation to offspring, the female elderly living alone in urban areas had a lower frequency of meeting with their children and also a lesser degree of intimacy with them because they lived at a distance. On the other hand, subjects living in rural areas and fishing communities had a higher frequency of meeting with their children and a greater degree of intimacy with them even if they lived at a distance. The study also showed that the female elderly living alone in the islands had a higher frequency of once meeting per three week with their offspring and a higher degree of intimacy with them because they all live in the same islands. In conclusion, the subject living in urban areas appeared to be isolated from their offspring as compared to the other seniors in the study. The female elderly living alone in urban areas suffered from an insufficient network of relatives and neighbors, and they experienced a poor quality of relationships to their offspring. Almost all of the lone seniors in the study had a low score in social activities; however, the female elderly living alone in urban areas revealed a higher level of participation in volunteer activities, group activities, and educational activities. Nevertheless, the lone seniors living in urban areas were not satisfied with their participation in social activities. The subjects living in rural in fishing communities and the islands showed more participation in money-making activities. This study suggests that the policies for female elderly living alone should reflect the differences of regional characteristics.

As our lifestyles have changed due to rapid industrialization and urbanization, new social and communication problems have been caused and there have been lots of discussion on regional communication. For communities to become alternatives with realistic meanings in this changed society, considerations on social and spatial conditions are needed. Therefore, public space which works as a device of physical environment for activation of communities needs more active changes which encourages social communication. In respect to the activation of communities, the following suggestions are given: First, physical devices of a urban plaza should be arranged to support various programs presented along with consideration of human behaviors as users. Second, fundamental facilities of the plaza should accommodate various activities through connections with programs and commercial space. Third, when cultural and historical characteristics of the community are understood, the plaza can form regionality and symbolism through artistic representation. And users can form the identity of community. Fourth, transportation facilities should be separated from or coexist with areas of passengers and the plaza should have its own identity through symbolic sculptures.

This research studied common opinions of parents about child welfare that have been diffused into urban communities in Korea. They were analyzed into major dispositions-anti-collectivists, reluctant collectivists, Fabian Socialists, Marxists-by demographic variables of sex, age, education, occupation, income, and religion. A questionnaire of 18 items was distributed to 1170 parents in the Seoul area who had more than one child under 18 years of age. The returns of 815 parents were analyzed with the statistics of frequency, percentage, and one-way ANOVA. The results of this study showed that (1) The opinions of parents on child welfare in urban communities had tendencies toward Fabian Socialists and reluctant collectivists ; (2) Major demographic factors were education and occupation, but the variables of sex, age, income and religion were not significant.

This study aimed to identify the determinants of physical frailty among the old-old adults in rural Korean communities. A total of 191 individuals aged 75 and older were included in the study, with the majority being female. Participants were classified into healthy (n=47), pre-frail (n=54), and frail (n=90) groups. Significant differences were found across these groups in terms of age, gender, education level, depression, and nutritional status. Multiple logistic regression analysis revealed that age (OR=1.16), depression (OR=0.21), malnourishment (OR=10.85), and short physical performance ability (OR=0.70) were significant predictors of physical frailty. These findings underscore the multifaceted nature of physical frailty among old-old adults in urban-rural complex communities and highlight the need for comprehensive and integrated interventions. Such interventions should consider not only physical factors but also broader health conditions and socio-demographic influences impacting the elderly. Further research is needed to develop and evaluate interventions that address these determinants and promote health equity among the elderly population in urban-rural complex communities

This study analyzed the changes in vegetation structure of Quercus mongolica communities, Pinus densiflora communities, Robinia pseudo-acacia communities and Pinus rigida communities for the last 11 years$(1994{\sim}2005)$ to provide basic data for ecological restoration. We studied the vegetation structure of four communities within a plot$(unit:\;1,200m^2)$) and concluded that Canopy Layer continuously preserved and expanded existing superior species, Understory Layer grew Styrax japonica which is highly adaptive to urban environment, and Shrub Layer grew more Stephanandra incise. An analysis on species diversity indicated that Quercus mongolica communities$(1.0921{\rightarrow}1.0381{\rightarrow}1.0633)$, Pin us densiflora communities$(0.7071{\rightarrow}0.8553{\rightarrow}1.0164)$, and Robinia pseudo-acacia communities$(0.9255{\rightarrow}0.8392{\rightarrow}0.8721)$ sharply decreased in 1998 and are gradually increasing these days. Also, Pinus rigida communities decreased from 0.9008 in 1998 to 0.8850 in 2005. Fluctuation in numbers of species and trees were similar. Acidity of soil was $4.34{\sim}5.31$ and improved compared to 20 years ago.

A clinical analysis was performed on 326 cases of the non-penetrating rib fractures experienced in the department of thoracic and cardiovascular surgery, Chosun University Hospital and 102 cases of the non-penetrating rib fractures those has been admitted and treated in the department of thoracic and cardiovascular surgery, Jeonnam Hwasoon lung-ang Hospital during a period from Jan. 1994 to Dec. 1995. 1. Sex ratio was 3.4:1 in urban and 3.6:1 in rural communities with male predominance. 2. Most· common cause were traffic accident in both communities. 3. Hemothorax, pneumothorax and hemopneumothorax which needed thoracostomy were observed iii 146 cases(44.7%) in the urban and 12 cases(11.7%) in the rural communities. 4. Left thorax was the spell site of rib fractures in both communiti s. 5. Rib fracture was prevalent from 3rd to 6th rib in both communities. 6. Open thoracotomy was performed in 37 cases(11.3%) in urban and 3 cases(2.9%) in rural communities. 7. Overall mortality was 4.29%(14 cases) in urban area and, 1.96%(2 cases) in rural communities, and cause of death were hypovolemic shock, brain edema, sepsis, respiratory failure, asphyxia, and cardiogenic shock.

Soft rot is a widespread, catastrophic disease caused by Pectobacterium carotovorum subsp. carotovorum (Pcc) that severely damages the production of Amorphophallus spp. This study evaluated the rhizosphere bacterial and fungal communities in Pcc-infected and uninfected plants of two species of Amorphophallus, A. muelleri and A. konjac. Principal component analysis showed that the samples formed different clusters according to the Pcc infection status, indicating that Pcc infection can cause a large number of changes in the bacterial and fungal communities in the Amorphophallus spp. rhizosphere soil. However, the response mechanisms of A. muelleri and A. konjac are different. There was little difference in the overall microbial species composition among the four treatments, but the relative abundances of core microbiome members were significantly different. The relative abundances of Actinobacteria, Chloroflexi, Acidobacteria, Firmicutes, Bacillus, and Lysobacter were lower in infected A. konjac plants than in healthy plants; in contrast, those of infected A. muelleri plants were higher than those in healthy plants. For fungi, the relative abundances of Ascomycota and Fusarium in the rhizosphere of infected A. konjac plants were significantly higher than those of healthy plants, but those of infected A. muelleri plants were lower than those of healthy plants. The relative abundance of beneficial Penicillium fungi was lower in infected A. konjac plants than in healthy plants, and that of infected A. muelleri plants was higher than that of healthy plants. These findings can provide theoretical references for further functional research and utilization of Amorphophallus spp. rhizosphere microbial communities in the future.

This paper theoretically explores the calculation of development impact fees focusing on urban growth, new urban development, developer, urban planner, housing, real estate market, community planning, community financing, local government, land use planning, public facilities, and development cost. Many questions related to who bears the burden of paying impact fees beg for answers based on empirical analysis. Those questions involve the extent to which landowners bear the burden, the effect of different levels of impact fees on the socioeconomic mix of communities, the distribution of fiscal benefits within a region where urban communities assess different levels of impact fees, and the preparedness of urban communities to accommodate development displaced by impact fees. Broader questions also relate to how urban and regional form is affected by differential application of impact fees throughout an area and whether money gained from the impact fees makes regional growth more or less efficient. Who ultimately pays development impact fees? There has been little empirical evaluation of how the market responds to development impact fees, but there is considerable information to suggest that, on the whole, the occupants - residents and users - pay the majority of the development impact fees.

As the rural economy is worsening day by day due to rapidly declined population and increase of aging generation, the emptiness in the rural areas are becoming increasingly intensifying. In particular, urban runoff of young adults and middle-aged people and the decrease in birth rate have shrunk the rural population reaching to raise concerns on the stage of emptiness. On the other hand, people in the urban areas with rapid industrialization and overcrowding call for the variety of housing needs moving away from monolithic housing types. In order to solve problems of rural communities such as emptied out rural society as well as the problems of urban communities in overcrowdings, environment, and housing, it is required to develop an urban-countryside village complex pursuing advantages of the rural environment and convenience of urban living. Of this time, there needs a change in rural development policies which can make the urban residents migrate and settle in the rural areas as they are naturally embracing the rural life according to the social background and demand.
