Recently many organizations have attempted to build hypermedia systems to expand their working areas to internet-based virtual work places. It is thus important to manage corporate hypermedia documents effectively. Metadata play a critical role for managing these documents. This paper identifies metadata roles and components to build its schema. Furthermore a meta-information system HyDoMiS(Hyperdocument Meta-information System) is proposed by the use of this metadata schema. HyDoMiS performs three functions; metadata management search and reporting The metadata management function is concerned with workflow document and database. The system is more likely to help implement and maintsain hypermedia information system effectively.

Korean societies have been experiencing the wholesale structural changes in the rapid currents of recent openness, globalization and democratization, which effect much more heavily in rural areas than in urban areas, so rural recomposition works being an important national concern. In order to systematically reconstruct the rural structure, the decision makers, with a four step hierarchy of rural resident-residents group-community-region, should be endowed with the objective judgement on basic elements of resource potentialities under their control. In this process. rational resource evaluation works would be firstly necessiated from expert groups. Based on the view mentioned above, this study principally aimed at developing a rational evaluation framework for rural resources. For that objective, the first step of the study pigeonholed the total resources items identifiable in rural areas from the existing study results, spatial planning and field surveying data. After then, using the formalized classification criteria of resources items, a tentative goal system for rural resources evaluation was proposed and the final one determined through expert-group checking. The results obtained during the study are summarized as follows ; 1. Using the existing examples of resources identification/classification and the basic data list for county-level development planning as the principal reference ones, total rural resources elements were classified into 3 constituent units : land, natural environment and human resources, which correspond to places to work, to play and to live, respectively, as 3 constituent ones of life-supporting space. 2. Three characteristic areal types were adopted to represent the total rural areas : lowland, upland and seashore areas, and also 3 practical use types to represent the objectives of resources evaluation systems : for land use planning, natural conservation policy and village improvement planning. Thus 9 different types of goal system for resources evaluation were developed(each system by 3 areal typesX3 practical use types) 3. Each goal system has 3-tier classification steps from the higher, middle and lower one. The higher and middle steps should contain equally applicable components to all the rural areas, of which allowable number being around 3 and 4 respectively. However the lower step would contain detailed sub-components changeable to areal characteristics of which allowable number being around 7.

Urban green areas or forest regions play an important role in lowering the air temperature of the surrounding areas. This cooling effect does not only affect inside of the green areas, but also extends into neighboring streets and buildings. In this study, the Land Surface Temperature (LST) are retrieved from the Landsat 8 satellite data for 8 clear days in Seoul, Korea from 2013 to 2015, and used for analyzing the cooling effect at an urban green region, Seonjeongneung, located in the southern part of Seoul. The LST distribution from the boundary of the Seonjeongneung presents that the cooling effect of the green areas was found to extend in many directions into the urban areas. The LST estimations of residential and commercial areas around the Seonjeongneung are also analyzed to assess how the green areas affect the type of land cover and the surroundings in the urban areas. Relatively lower LST for the residential areas from the Seonjeongneung boundary ranges from 100 to 250 m, resulting in an average cooling effect of $2.3^{\circ}C$. On the other hand, the LST distribution in the commercial areas shows that the effective distance of green areas are relatively low in the range of 0 to 200 m, which means the average cooling effect is approximately $0.3^{\circ}C$. This result shows that the cooling effect of the Seonjeongneung is clearly noticeable, particularly, the residential areas show greater cooling effect than commercial areas.

This study was designed to investigate the relationships between children's physical growth and health and their raising conditions and to find out the important conditions to improve their physical growth and health. The rasing conditions were classified into three major parts; i. e., family conditions, conditions of nutrition up-taking, and conditions of rest or sleep and exercise or play. Then, the questionnaire including the items to survey these three areas of raising condition and the items to evaluate the health status were given to children' mothers or fathers and filled up by them. The data of their 4 anthropometric measures; body weight, stature, sitting height and chest girth, were also collected from their latest records of health examination. The data of health status were converted to health scores representing 6 domains of health; digestive organs, respiratory organs, auto-nerve systems, fatigue, others and health as a whole. Then, correlations of raising conditions were determined with four antropometric measures and 6 health scores as criterion variables. Then, number of families to live together, and child's birth order in the domain of family conditions, habits of unbalanced diet, eating frequency of eggs, fruits, green and yellow vegetables, light colored vegetables, milk products in the domain of nutrition up-take, and the time for study at home, the place for play, the number of friends to play with together, the hours for playing out of door, the hours for playing sports, and the hours to move their body for assisting house keeping were picked out to investigate their relationships with physical growth and health status. Then, their habits of unbalanced diet and eating frequency of eggs, green or yellow colored vegetables, and milk products were found more influential conditions and more over, birth order, the time for study at home, the time to play out of door showed moderate degree of connection with physical growth and health status in early childhood.

Due to the rapid rise of artificial intelligence technology around the world, SW education conducted in elementary and secondary schools is expanding including AI education. Therefore, this study aims to present an AI education system based on 4P(Play, Problem Solving, Product Making, Project) that can be applied from kindergarten to high school. The AI education system presented in this study is designed to be applied in 4P-based Play, Problem Solving, Product Making, and Project 4 stages so that it can be applied by school age and step by step. The level was presented by dividing it into two areas: AI literacy and AI development. In order to verify the validity of the developed AI education system, the Delphi method was applied to 15 experts who had experience in SW education or AI education. The AI education system derived as a result of the verification will be able to contribute to the development of a content system for AI education at each school level in the future.

With the development of blockchain technology, play-to-earn (P2E) games, one of the decentralized applications (dApps), are receiving great social attention. P2E games are positively evaluated as areas with high growth potential based on blockchain technology, and at the same time, they are negatively evaluated as speculative as people can cash P2E game items in the form of cryptocurrency. In this situation, the purpose of this study is to investigate factors affecting the intention to use P2E games. Along with the discussion of hedonic system adoption, we consider the factors with perceived enjoyment, economic incentive, and social influence. In order to verify our research model, data were collected from 350 adults with P2E game experience or recognition, and a structural equation model was carried out. The analysis results find that perceived enjoyment and subjective norm have a significant positive effect on the intention to use P2E games, and economic incentive does not have a significant effect. In addition, peer influence and external influence have a significant positive effect on subjective norm. Drawing on these findings, we present several academic and practical implications for future research.

The purpose of this study was to compare the different environment among the young children of large and small cities and rural areas in Korea, in order to know how these different environment have an effect on the children's intellectual and emotional development. For this subjects, 2,700 questionares with 51 items were distributed to the infants' mothers in each area to interview and answer. About 1,800 questionaires were gathered from 3 metropolitan, 6 cities and 6 rural areas in (each 2 farming, fishing and mining villages) The results of analyzing these questionaires were like following; 1. The average number of children of each family was 2.5 in large cities, 3.0 in small cities and 3.6 in the rural areas. 2. White about 75% of infants' parents of large cities graduated college education, only 6% of the rural parents did it. Most infants' parents of the rural areas have only graduated the elementary school. 3. About 90% of the rural, small and large cities family have had radios and T.V sets, and 90% of infants watched T.V program for 2 hours a day in average. 4. While about 50% of large cities' young children were not reared by their mother's milk but by milk and other foods, about 95% of rural infants by breasting mills. 5. Young children of large cities were wearing about 5 months earlier than those of the rural. 6. While 20% children of cities were taught in the kindergarten, most children of the rural areas could not be taught in the kindergarten. 7. About 45% young children of the rural areas and cities were understood and taught reading, writing letters and numbers by their parents, brothers and sisters before entering primary school. 8. While 50% young children of large cities have had pianos and were taught music in kindergarten or piano tutor's, most of the rural areas have not had pianos and could not be taught music. 9. Most children's favorite music songs were T.V signals or C.M songs in both the rural and cities. 10. While most children of cities have had lots of children's pictures or fairy tale books. most infants of the rural areas have had nothing or a few. 11. As lots of infants could not find their pleasure resorts of sport tools outside, they used to play in side streets or publicroads with their friends. 12. While most infant's parents in cities wanted to make their infants lawyer or medicine doctor, most parents in rural areas wanted to make their children teacher or technician. 13. About a half of Korean infants have had their own rooms or have lived in it together with their brother or sister. In conclusion, as children of large cities have had more various kinds of cultural circumstances than the rural areas in aspects of cultural institutions' tools and environment of their parents' education, books, toys, pleasure resorts and their own rooms, the intellectual development of the former could be considered to surpass those of the latter. In other words, the average IQ points of urban's young children are 10 point higher than those of the rural areas, which means the better circumstance would affect the infant's intellectual development. Therefore, the government must support to make good circumstances of the children in the rural areas.

The object of this study is to investigate the satisfaction level of group homes for the elderly living alone in rural areas. Sixty-four elderly people, living alone, were selected from ten regions operated by the Gimje city council in Jeonlabuk-do, and then a survey was conducted during January 17 to 26 in 2011. The results of the investigation are as follows: first, roughly 90.6 percent of the participants responded that they were satisfied with cohabitation. Second, average point of satisfaction was going to bed together, which is 4.39, also each unit in all the ten regions was recorded above 4.00. Third, the satisfaction of eating together averaged highly at 4.37. Fourth, 95 percent of them were satisfied with the conditions of the residential space. Fifth, the satisfaction with the amenities, such as electricity, phone, heating and sanitation, averaged 96.9 and 98.4 percent each, which was rated highest. Through analytical research, elderly people who live in 'group homes' are satisfied with their lives. It is thought that this 'group home' can play the role of an alternative family better than existing 'senior citizen centers' and 'welfare centers for the elderly'. The study means that 'group homes' in rural areas could be established successfully.
