Researchers' common findings is that there are positive or negative effect of alcohol expectancy on drinking behavior. Therefore we would effectively prevent troublesome drinking of the youth and university students by inquiring and controlling critical factors affecting alcohol expectancy. The purposes of this thesis are, first, to empirically test factors affecting the alcohol expectancy level of elementary schoolchild(potential drinker).; second, to suggest the necessity for development of pre-alcohol prevention programs. On the basis of previous research, eighteen factors included in four categories(general characters, environmental characters, alcohol knowledge, drinking experience) affecting alcohol expectancy level were found out. 623 subjects used in this study were drawn from 8 elementary schools in Daegu, Korea. The empirical results suggested that the alcohol expectancy level of elementary schoolchildren was negative in general. And it was proved that 9 factors were significantly correlated with alcohol expectancy level. To put it concretely(see Fig.), (1) It was proved that schoolchildren with bad environment(live in oneself, displeased drinking feeling) rather than good environment(live with parents, nice drinking feeling) for drinking had more negative alcohol expectancy. (2) Korean traditional culture that partakes of sacrificial food and drink have an influence on the first drinking of most elementary schoolchildren. And it was proved that schoolchildren with this drinking experience rather than any other motives had less negative alcohol expectancy. (3) It was proved that schoolchildren adapting themselves rather than being difficult in school life had more negative alcohol expectancy. And the more knowledge about alcohol or drinking schoolchildren had, the more they had negative alcohol expectancy (4) It was proved that schoolchildren having drinking experience or drinking at present rather than having no drinking experience or not-drinking at present had less negative alcohol expectancy. (5) It was proved that schoolchildren having strong drinking intention rather than having weak or no drinking intention in the future had more positive alcohol expectancy. Based on previous results, guideline for development of pre-alcohol prevention programs can be represented: discriminated programs development on educatee, drinking education programs development increasing the power of self-control about alcohol and drinking, social education or continuing education programs development on drinking, open preschool education to substantially prevent drinking or alcoholism etc. The findings, however, should be interpreted with caution, because this study has several limitations in measurement and sampling as follows. First, selection bias because of limited selection of sampling. It is because the subjects are drawn from only 8 elementary schools in Daegu. Second, less refined measurement ; Therefore, it is necessary to develop more detailed measures on alcohol knowledge, alcohol expectancy level especially. Further researches should be suggested and encouraged with more refined methodologies.

The purpose of this study was to investigate the effect of learning flow, problem solving ability, professor-student interaction of academic achievement in nursing students. Data were collected from 274 nursing students in B city and analyzed by t-test, ANOVA, Pearson correlation coefficient, and hierarchial multiple regression using SPSS/WIN 22.0. The degree of academic achievement in nursing students was 3.70±0.70. There were significant differences in academic achievement with grade(F=4.755, p=.003), campus life satisfaction(F=5.643, p=.004), major satisfaction(t=5.794, p=.003), adapting to COVID-19(F=7.961, p<.001), satisfaction to non-face-to-face environment class(F=18.353, p<.001). There was positive correlation between academic achievement and learning flow(r=.649, p<.001), problem solving ability(r=.333, p<.001), professor-student interaction(r=.479, p<.001). The factors affecting academic achievement of the study subjects were learning flow(β=.563, p<.001), professor-student interaction(β=.280, p<.001), with an explanatory power of 52.0%. Therefore, strategies increase the academic achievement of nursing students in untact lecture, and environment improvement to increase learning flow and professor-student interaction are needed.
This study screened three natural ores (iron, mangenase, and zinc), two types of slags, and two elemental metals (elemental iron and zinc) to evaluate transformation characteristics of CAH mixtures [e.g. Carbontetrachloride (CT), 1,1,1-Trichloroethane (1,1,1-TCA), and Perchloroethene (PCE)]. To select an effective metal medium to treat the CAH mixtures, we measured transformation capacities (CAH mass ultimately transformed/mass of metal added) and the degree of dechlorination. We also considered economical efficiency of the metal media by comparing the value, CAH mass ultimately transformed divided by the price of metal medium added. A simplified mathematical model adapting CAH transformation capacity, first-order transformation kinetics, and available mass of metal transforming CAH was developed and used for estimating CAH transformation rate coefficient and longevity of the metal medium. CAH transformation capacity for elemental iron and elemental zinc were 4258~7129 and $4215{\sim}6330{\mu}g\;CAH\;transformed/g$ metal added, respectively, which are a factor of 80~200 higher than slags and natural ores. They also showed a factor of 1.1 to 2.2 greater degree of dechlorination than the others. Among natural ores and slags, Zinc ore showed the highest transformation capacity, $47{\sim}53{\mu}g\;CAH\;transformed/g$ metal added. Although zinc ore have smaller transformation capacity than elemental metals, economical efficiency of zinc ore is a factor of 10~20 greater than elemental metals tested. Consequently, zinc ore would be more economical medium than the others tested in this study. We estimated the pseudo first-order transformation rate of zinc ore was in the order of CT > 1,1,1-TCA > PCE.

This study examines garden activity and garden plant preferences for development of the garden activity program using community garden aimed for communication and integration for multicultural age. As a result, for members of multicultural society had high portion of floral arrangement and crafts, growing plants in both indoors and outdoors garden for their garden activities, and using plants for cooking, growing plants in both indoors and outdoors garden was of higher portion for native korean. In the garden plant preferences, members of multicultural society liked ornamental plants the best, due to the environmental correspondence between the plant's place of origin and their home country, while native koreans tend to prefer vegetables, reflecting the recent interest in pro-environment crops and rise in demand of urban farming, veranda gardening and weekend farming. In this study, the garden activity program for communication and integration categorized the value of garden activity into three categories; the value of respect for life, the value of consideration through caring, the value of plant ethics, based on the above preference results. The value of respect for life can be achieved by understanding the meaning of life, experiencing the will to live, and understanding the characteristics of plants and me. The value of consideration of caring comes from waiting and nurturing for living things that are different from me and adapting to the environment as a living The value of plant ethics can give us the insights for human relationships, by understanding and experiencing the natural ecosystem and plant co-existing in it. The eight-session garden activity program also went through validity verification process by experts on gardening and multiculture, and the effectiveness of the program was proved.

This study was conducted using deep learning technology to classify for 'Mihwang' peach maturity with RGB images and fruit quality attributes during fruit development and maturation periods. The 730 images of peach were used in the training data set and validation data set at a ratio of 8:2. The remains of 170 images were used to test the deep learning models. In this study, among the fruit quality attributes, firmness, Hue value, and a* value were adapted to the index with maturity classification, such as immature, mature, and over mature fruit. This study used the CNN (Convolutional Neural Networks) models for image classification; VGG16 and InceptionV3 of GoogLeNet. The performance results show 87.1% and 83.6% with Hue left value in VGG16 and InceptionV3, respectively. In contrast, the performance results show 72.2% and 76.9% with firmness in VGG16 and InceptionV3, respectively. The loss rate shows 54.3% and 62.1% with firmness in VGG16 and InceptionV3, respectively. It considers increasing for adapting a field utilization with firmness index in peach.
Forest soil carbon model is a useful tool for understanding complex soil carbon cycle in forests and estimating dynamics of soil carbon to climate change. However, studies on development and application of the model are insufficient in Korea. The need for development of Korean model is now growing, because there are notable problems and limitations for adapting overseas models in Korea to meet the requirements of the international organizations such as IPCC, which demands highly reliable data for national reports. Therefore, we have studied 7 overseas forest soil carbon models (CBM-CFS3, CENTURY, Forest-DNDC, ROMUL, RothC, Sim-CYCLE, YASSO), analyzed and compared their structure, decomposition mechanism, initializing process and, input and output data. Then we evaluated applicability of these models in Korea with three criteria; availability of input data, performance of model, and possibility of regional modification. Finally, a systematic process for applying a new model was suggested based on these analyses.
The history of Korean Pungsu can be approached from two perspectives. One is through the history of its theoretical formation and evolution, and the other is through the history of its social and cultural formation and evolution. The former, i.e. Pungsu theories, was produced and developed by intellectuals as an elaborate system of cosmic knowledge and logic. The latter, i.e. Pungsu culture, was consumed and adopted by various social groups in their spatial life practices. It was Chinese intellectuals that originally initiated and carried out the production, formation, and development of the fengshui theoretical system. Intellectuals in neighboring countries adapted Chinese fengshui to their local environment, incorporating their own historical and cultural features, and practiced this transformed and indigenized form of geomancy. The evolution of Korean Pungsu can be summarized as having the following five characteristics. First, Koreans accepted fengshui from China, pragmatically adapting it to fit the Korean natural and social environment, and then used it for social discourse on space. Second, Pungsu had a comprehensive and varied influence on Korean culture throughout its different historical periods. Third, combined with social thought led by differing social classes, Korean Pungsu existed as an element of social discourse. Fourth, Koreans' theoretical preferences of fengshui were for the landform method over the liqi (理氣) method. Fifth, the Bibo philosophy was a characteristic feature of Korean Pungsu.

This paper proposes a Web Service framework on both wired and wireless network environment that can be interoperable and extensible among geo-spatial servers. Mostly, OGC has studied and announced international standards which are related to web services on various kinds of geo-spatial data. Therefore, the proposed framework satisfies interoperability and extensibility for geo-spatial servers by adapting WMS, WFS, WCS, and WRS standards of OGC and web services standards of W3C. This framework, also, satisfies requirements of huge volumed data service, GML service, geo-spatial function service, and wireless network service. This framework consists of geo-spatial servers group, geo-spatial broker, and web-based client. The geo-spatial servers group includes GIS, SIIS, ITS, GNSS, and Telematics server for the purpose of providing various kinds of geo-spatial services. Especially, this paper proposes main memory based GIS server(MMG server) that can efficiently serve huge volumed GML data on wireless network environment. Finally, experimental results about the MMG server and prototype implementations of the framework show the effectiveness of this study.

This study attempts to explore settlement and adaptation status involved in differing urban-to-rural migration types in Gyeongbuk Province and suggests policy implications based on this analysis. The attributes of urban-to-rural migrants in Gyeongbuk Province differ spatio-temporally, and their status of settlement and adaptation is also different depending on urban-to-rural migration types. "U-turn" migrants who are mostly first-generation rural-to-urban migrants with experience in farming and rural community life engage primarily in crop agriculture. "J-turns" and "I-turns," who have no experience in farming or rural community life, migrated for idyllic rural life. The household income of these types is relatively low compared to U-turn type. U-turns' degree of adaptation is relatively lower than the other types, and U-turn migrants mainly rely on family and community assets in order to solve problems. J-turns' and I-turns' degree of satisfaction is relatively high. However they typically have substantial difficulties in adapting due to lack of pre-migration preparation. Policy implications are : 'switching away from general and inclusive policies of support,' 'transition to policies embedded in the attributes of regions and migration types,' 'improvement of policy governance,' 'enhancement of support for pre-migration preparation and customized support based on the needs of migrants,' and 'comprehensive improvements of settlement environment to better integrate migrants with current residents.'.
Considering the characteristics of the Korean family which maintain a close connection with their patients from the moment of their falling sick to hospitalization to discharge, the family is the most important environmental factor of the social supporting system, and is the important object of the client as well as activity system. The medical social work intends to meet the practical needs of aged chronic patients, providing them and their family with a professional human service. The end of this study is to find out the hardships of both the aged chronic patients and their family as well as their needs for the social welfare service, and to search out the way of comprehensive social work service. The summary of the analysis of the survey is as follows: 1. The needs of aged chronic patients are divided into those of the solution of the problems of falling ill, social welfare program and discharge. Those needs arc affected by the various factors of the types of hospitals, the patients' age, the kinds of insurance, and the supporting systems, etc. Accordingly, the assessment of the needs of the patients are asked to be done comprehensively in accordance with the kinds of diseases and social environments. 2. The importance of the family to the aged chronic patients is evident. The family plays a decisive role in the patients' hospitalization and discharge, the family being an important supporting system and making it necessary to take an approach to client system. The family has difficulty in getting connection of community resources, in adapting to social life after the patient's discharge, and in paying the treatment. The family suffers the secondary hardships more than the burden of the treatment expenses. 3. For this reason various interventions are needed to reduce the stress caused by supporting and nursing patients. Thus the social welfare service for the aged chronic patients and their family needs the following prepositions: 1. It is the characteristics of the aged chronic patients that they need continuous care and that the strengths of the patients and their family cannot be too much emphasized, and that comprehensive assessment based on the connection 'with the community and the mutual interchange 'with the environment, is much emphasized. 2. The family of the aged chronic patient is a resources system as well as a client one. 3. Another characteristic of the aged chronic patients is that with the resources connection in mind, it needs an active intervention of social workers in the community. With these prepositions considered, the development of practical social work service for the aged chronic patients is thought urgently needed.
