The purpose of this study, which focuses on safe living as an important determinant of the quality of life for the elderly, is to provide policy proposals for their safe living in rural areas by examining their current living conditions and related policies. To examine the related policies, we analyzed government plans including: the first, second and third Basic Plan on Low Fertility and Aging Society, first implemented in 2006, the first, second and third Basic Plan for Healthy Families, also first implemented in 2006, and the first, second and third Five-year Plan for Improvement of the Quality of Life of Rural People and Regional Development of Rural Areas, first implemented in 2005. In addition to these plans, government projects concerning safe living environments were assessed. we present the following policy proposals for the safe living of the elderly in rural areas. First, integrated, customized policies are required for the rural elderly's everyday life. That is, elderly-friendly residential improvement policies are needed since accidents involving the rural elderly usually occur in their own houses. Policies should also be introduced to monitor and improve the elderly's nutritional and health status. Also considering the high proportion of elderly people in rural areas, policies must be aimed at creating elderly-friendly and family-friendly villages. Second, educational sessions for the elderly are necessary to raise their awareness of safety in everyday lives, which they often overlook.

Barnyard millet is a short-lived tropical, short-term C4 plant and has superior vitality in humid conditions owing to its freshwater habitat. It shows strong adaptability to soils with poor drainage and low fertility, and efficiently competes with rice in paddy fields. Barnyard millet grain is used as feed in the Indian region and is a great source of dietary fiber, proteins, fats, vitamins, and some essential amino acids. Considering its high nutritional value and its potential as a food resource and fodder crop, various countries are showing interest in cultivating barnyard millet. However, in Korea, farm households have not yet recognized the benefits of cultivating barnyard millet, and research regarding this is scarce. In this review, the features of forage barnyard millet and its related research trends are discussed, with the aim of improving interest in this crop and promoting its cultivation.

This study started with the aim of creating a parenting environment for raising children as a solution to the problem of low fertility. Communal housing is a type of housing where professional childcare environment and lives of family with children can be achieved in community space. It is an environment that supports the development of the child and life of family. However, there is no guidance system for planning such an environment. Therefore, this study aims to develop a pattern language for communal housing of families with children. The research method comes in two steps. First, the documents that provided pattern language and design guidelines about the environment of child and families with children were analyzed. Second, experts specialized in child education, women and family, environmental design were interviewed. As a result of analysis of characteristics of derived pattern language, convenience, safe feeling, comfortability in residential unit, movement, safe feeling, convenience in intermediate space convenience, safe feeling, control in community space were high. The pattern language of this study grafted the items that have proven to be important over a long period of time and the environmental design concepts for families with children in the community space. So it enabled differentiation from existing pattern language or design guidelines.

Due to the rapid pace of low fertility and aging of Korea, population decline is rapidly progressing in the outskirts of the province and county. Demand for public transport is decreasing due to suburban population declines, while local government funding for maintenance of the bus system is expected to increase gradually. The government and municipalities are promoting the introduction of Demand Responsive Transport (DRT) in order to reduce the burden of financial support for buses while enhancing mobility of the residents in vulnerable areas. However, most DRTs in Korea have been operated mainly in the areas that are not provided with public transportation services. Although DRT is able to reduce the financial burden of local governments, it is not easy to be introduced because of the objection of the existing bus users. In this study, 11 out of 61 towns with poor public transportation services in Gyeongsangnam-Do were selected for the introduction of DRT to replace bus services by using village characteristics. The results of this study are expected to be used as a basis for decision making to use DRT instead of bus service for the burden of bus financing for local governments.

Low fertility rates and increased life expectancy further exacerbate the process of an aging society. This is also reflected in the gradual increase in the proportion of vulnerable groups in the social population. The demand for improved mobility among vulnerable groups such as the elderly or the disabled has greatly driven the growth of the electric-assisted mobility device market. However, such mobile devices generally require a certain operating capability, which limits the range of vulnerable groups who can use the device and increases the cost of learning. Therefore, autonomous driving technology needs to be introduced to make mobility easier for a wider range of vulnerable groups to meet their needs of work and leisure in different environments. This study uses mini PC Odyssey, Velodyne Lidar VLP-16, electronic device and Linux-based ROS program to realize the functions of working environment recognition, simultaneous localization, map generation and navigation of electric powered mobile devices for vulnerable groups. This autonomous driving mobility device is expected to be of great help to the vulnerable who lack the immediate response in dangerous situations.

This study was conducted to investigate the status and prospects of seed quality researches in rapeseed. Rapeseed Quality was mainly related to oil and protein content, fatty acid composition and glucosinolate content. Hence, breeding for improvement of rapeseed Quality has been emphasized as follows: 1) inheritance mode, 2) investigation of germplasm, 3) establishment of analysis technique, 4) establishment of selection method, 5) idealization of cultural technique. The oil quality is determined by its fatty acids. Fatty acids have been determined by gas chromatography. To improve oil quality was emphasized for zero erucic acid, the highest possible linoleic acid and the lowest possible linolenic acid content. Rapeseed meal is not considered as top quality feed ingredient although it has higher protein content and well-balanced amino acid composition. This is mainly because of the presence of considerable amounts of glucosinolates. Thus the reduction of glucosinolate content in rapeseed meal is of great importance. In breeding for meal quality, low glucosinolate lines (plants) were selected and analyzed by gas chromatography and UV-spectrophotometer. Current problems and future researches of rapeseed quality in Korea are 1) improvement of researcher's number and facilities, 2) depression of animal feeding trials, 3) unsatisfied relationship between research and manufacturing and products field, 4) improvement of fertility for yellow and thin seed coat lines crossed between mustard and rapeseed, 5) establishment of new rapid analysing system for rapeseed quality.

School closures in rural areas is especially relevant because low fertility rate and population aging are common not only in rural but also in urban areas. This paper examined a variety of users' perceptions on welfare facilities using closed rural schools. For this study, the descriptive survey research design was conducted at the EZER located in Kyungsnangbuk-do. The sample size of 200 was selected through convenience sampling and data collection was completed by a self-completion written questionnaires. Main findings are as follows: 1) the level of users' relative satisfaction with welfare facilities using closed rural schools was generally positive, main factor associated with relative satisfaction was facilities and surrounding environment at closed rural schools, 2) socioeconomic usefulness of closed rural schools was also was generally positive, main factors for revitalization were adequate facilities and places, accessible and convenient places, 3) future necessity and willingness for welfare facilities using closed rural schools were overwhelmingly positive, children or youth were revealed as a priority service target. Finally, theses analyses show that a high proportion in the rural welfare sector, especially seemed to have a positive impact on bridging negative gabs between urban and rural in the socioeconomic development and social welfare.

The objective of this study is to identify the significance of haying many children, their motive of childbirth, patterns of investment in human capital, and their expectations of their children. For this purpose, thirteen mothers of multi-child families have been interviewed in depth. Key findings of the study are as follows. First, the significance of children in many-child families varied. The fundamental features were: symbol of strong ties between God and humans, proud existence displayable to others about their level of happiness, and a means of defining their identity. Second, the typical motives of the majority of interviewees to have many children were "unplanned" but "natural accommodation and adaptation." Third, striking aspects, in terms of many-child families' investment in human capital were to consider many-child families to be a community in itself as a great environment of teaming and to have to deal with issues of limits and impartiality when allocating resources of a limited income and parents' time. Fourth, expectations of parents for their children were "normal growth" and mediocrity, and they cited intangible human assets as the greatest gift to their children. This study will hopefully offer a new analytical perspective to the growing concerns of low birth rates and excessive zeal of parents for their children's education, and thereby lay the groundwork of methodological approaches for resolving such social problems.

Reproductive biotechnologies continue to be developed for genetic improvement of both river and swamp buffalo. Although artificial insemination using frozen semen emerged some decades back, there are still considerable limitations. The major problem appears to be the lack of efficient methods for estrus detection and timely insemination. Controlled breeding experiments in the buffalo had been limited and similar to those applied in cattle. Studies on multiple ovulation and embryo transfer are essentially a replica of those in cattle, however with inherent problems such as lower number of primordial follicles on the buffalo ovary, poor fertility and seasonality of reproduction, lower population of antral follicles at all stages of the estrous cycle, poor endocrine status and a high incidence of deep atresia in ovarian follicles, the response in terms of transferable embryo recovery has remained low with 0.51 to 3.0 per donor and pregnancy rates between 15 to 30%. In vitro production of buffalo embryos is a valid alternative to recovery of embryos by superovulation. This aspect received considerable attention during the past decade, however the proportion of embryos that develops to the blastocyst stage is still around 25-30% and hence the in vitro culture procedures need substantial improvement. Embryo cryopreservation procedures for direct transfer post thaw need to be developed for bubaline embryos. Nuclear transfer and embryo cloning is a technique that has received attention in various species during recent years and can be of immense value in buffaloes as they have a low rate of embryo recoveries by both in vitro and in vivo procedures. Gender pre-selection, genome analysis, gene mapping and gene transfer are a few of the techniques that have been studied to a limited extent during recent years and are likely to be included in future studies on buffaloes. Very recently, reproductive biotechnologies have been applied to feral buffaloes as well, but the results obtained so far are modest. When fully exploited they can play an important role in the preservation of endangered species.
