There are now many different commercial weather sensors suitable for smart farms, and various smart farm devices are being developed and distributed by companies participating in the government-led smart farm expansion project. However, most do not comply with standard specifications and are therefore limited to use in smart farms. This paper proposed the connecting structure of operating non-standard node devices in smart farms following standard specifications supporting smart greenhouse. This connecting structure was proposed as both a virtual node module method and a virtual node wrapper method. In addition, the SoftFarm2.0 system was experimentally operated to analyze the performance of the implementation of the two methods. SoftFarm2.0 system complies with the standard specifications and supports non-standard smart farm devices. According to the analysis results, both methods do not significantly affect performance in the operation of the smart farm. Therefore, it would be good to select and implement the method suitable for each non-standard smart farm device considering environmental constraints such as power, space, distance of communication between the gateway and the node of the smart farm, and software openness. This will greatly contribute to the spread of smart farms by maximizing deployment cost savings.

This study was conducted to investigate the consumption of milk, along with satisfaction for improvement of the school milk program in middle school. The subjects were 447 middle school students(265 male, 182 female) in the Gyeonggi area, whowere asked to fill out the questionnaire. The collected data were analyzed by a SAS package. The results showed that 53.2% of the subjects were participating in the school milk program. Regarding the frequency of milk consumption, 77.7% of students reported daily milk consumption and 65.3% of students reported they drank milk when it was available. 56.8% of the students responded that they were satisfied with the school milk program. Male students not participating in the school milk program cited the reason as "eating at home", while non-participating female students cited the reason as "tasteless". When asked whether they accepted or rejected the school milk program, male students(97.7%) and female students(97.8%) answered "it should be executed". To improve the school milk program, most of the students(72.2%) stated that "it should be selected among flavored milk(strawberry, banana, chocolate, black bean, and husked rice milk) instead of white milk". Therefore, in order to increase the intake of milk, the students should develop the habit of drinking milk to gain the attention of parents. Also, schools should attempt to help through offering proper dietary education.

This study analyzed investment effects for Practical Field Studies conducted by the KOPIA (Korea Program on International Agriculture) centers, which are part of the ODA project operated by the Rural Development Administration. Focusing on the productivity and effectiveness factors of each project, a questionnaire survey was sent to each KOPIA center associated with each project. The results demonstrated the production and profitability of farms participating in the pilot project were significantly improved compared to those of farms that did not participate in the project. Also, in the satisfaction results of taste, nutrition, and freshness, the participating firms could significantly improve them when being compared to those of non-participating farms. It is highly expected to contribute to improving the operational effectiveness of Practical Field Projects conducted in Africa based on the results of each project's performance and economic feasibility. This study also can lead to a change in the social perception of ODA projects by raising people's awareness of ODA projects.

The purpose of this study is to understand and investigate the process of making negotiation strategy to do leisure activity with overcoming leisure constraints which highschool students participating in their club activity meet. For this study, students who have at least one-year career for their club activity -more than two times a week and two hours at a time -were selected. Survey through in-depth interview, non-participating observation and field note were conducted. The results are as follow. Firstly, the fascination for club activity was the important factor for overcoming leisure constraints. Secondly, leisure constraints never let students stop doing their activity. Thirdly, the subjects of this study practiced negotiation strategies and came to have self-achievement and self-esteem, improving their relationships effectively. Finally, it was found out that they were creating their own club culture with continuous leisure constraints negotiation. The results of this study present the case and the method of continuous students' participation in their leisure and are able to help them to build up their positive leisure experiences.

Purposes: When rehabilitation services are provided remotely using information and communication technologies to patients living at home, there is an advantage in providing rehabilitation services to individuals in their everyday social and physical environment, which can improve functional outcomes and satisfaction. The purpose of this study was to analyze the effectiveness of the pilot project by analyzing the outpatient and inpatient medical use and expenses of patients who participated in the rehabilitation patient home-based care pilot project. Methodology: To analyze the effectiveness of the home-based care pilot project for rehabilitation patients, health insurance claims data from the Health Insurance Review and Assessment Service was used. The subjects of analysis were patients who had undergone major lower extremity joint replacement surgery, including hip, knee, and ankle joint replacement surgery, and patients who had lower extremity fracture surgery, which were the targets of the rehabilitation patient home-based care pilot project. To compare medical use and expenses between patients participating in the rehabilitation patient home-based care pilot project and those not participating, chi-square test, t-test, and multiple regression analysis were performed. Findings: As a result of analyzing the number of medical use cases and expenses of patients who participated and those who did not participate in the rehabilitation patient home-based care pilot project, the average outpatient medical use and outpatient medical expenses per person for participating patients were lower than those for patients who did not participate. The average hospitalization cost per person and the average length of stay per person were also lower than those of patients who did not participate. Practical Implications: Home-based care for rehabilitation patients continues to provide medical services at home, not at medical institutions, and can be expected to reduce readmissions and complications by resolving patients' emergency situations at home or on their own, thereby reducing medical use.

The purpose of the study was to prove the effect of the "Picture Book Reading Program for Mothers" developed to enhance the language competence of married immigrant women and their children. Twenty immigrant mothers with three-year-olds were recruited, and they participated in an 8-week-Picture Book Reading Program developed by the reseacher. The REVT and U-TAP were used to measure linguistic abilities for mothers while PRES was used to measure their children's linguistic abilities. Lee(2004)'s "Effect of dialogic picture book reading teacher training program for toddlers" was used to measure the mother's and children's verbal and non-verbal behaviors. The results of the study were as follows: First, by participating in the PBRPM, the mother's linguistic ability as well as children's vocabulary and receptive language have increased. Second, by participating in the PBRPM in terms of mother-child interaction, mother's verbal behaviors to children (i.e. attention and inquiring) and children's verbal behaviors(i.e. responding and imitation) have increased. In conclusion, "PBRPM" for married immigrant women and their children proved to be effective in enhancing the language competence and verbal interactions between married immigrant women and their children.

Objectives: This study examines the relationship between social capital and suicidal impulse for the Metropolitan Seoul residents, paying particular attention on individual and area level risk factors using multilevel analysis techniques. Methods: Data are obtained from the 2005 Seoul Health Indicators Survey and the Seoul Survey. At the individual level, we analyze demographic variables including sex, age, marital status, educational attainments, family income, field of economic activities, having close friends or relatives, and having participating groups or organization. To measure the area level social capital, happiness index, attitude toward minority, the percent of volunteer activity, the percent of having close friends or relatives, and the percent of participating groups or organization are considered. A multilevel logistic regression analysis is conducted utilizing the SAS 9.1. Result: Results show that non-aged, female, not currently married, unemployed individuals tend to have relatively high motivation of suicide. Controlling for individual level covariates, the relationship between social capital and suicidal impulse is neither significant nor substantial. Further, the consideration of area social capital does not explain the variances in suicidal impulse across 25 Kus. Conclusion: Suicidal impulse among Seoul residents is mainly attributable to the composition of individual characteristics but little to the contextual social capital.

This paper empirically studies the effect of public procurement on small and medium-sized enterprises (SMEs) in the Republic of Korea using firm-level data. Public procurement, the purchase of goods and services from private firms by the public sector, is regarded as an important policy measure for providing support to firms, particularly SMEs. This study uses establishment-level panel data of the mining and manufacturing sectors from the Korean National Bureau of Statistics (Statistics Korea) and procurement history from the Korean Public Procurement Service to empirically estimate the effects of public procurement on firms' productivity (total factor productivity) and survivability. Using a propensity score matching estimation method, we find that participating firms showed higher productivity than non-participating ones in the control group only for the year of participation, that is, 2009. After two years, in 2011, they exhibited significantly lower productivity. In contrast, establishments that participated in public procurement for SMEs in 2009 were more likely to survive than those that did not do so in 2011. These results can be interpreted as the negative consequences of government intervention. The market's efficiency enhancement is hindered if underserving companies survive owing to government intervention but fail to improve efficiency.

If one is looking for an organization that will be responsive to community needs, stimulate economic growth, and raise people's income, cooperatives should be an obvious choice (Calkins & Ngo, 2005; Larocque et al., 2002). This paper investigates whether the households' income is affected by the access to cooperatives for the case of Phong Dien district, Can Tho city of Vietnam. Data used are directly collected from 250 households that are both participating (120 observations) and not participating in the cooperatives in Truong Long, Tan Thoi, Nhon Ai and Nhon Nghia communes. By using the Probit model, the findings show that there are three statistically significant factors affecting the ability of farm households to participate in the cooperatives at the 1 percent level including land area, distance to market center, and education level. In addition, the PSM model analysis suggests that the average income of cooperative members is significantly higher than that of non-members, about 40.880 million VND/year at the significance level of 1 percent. The empirical results imply that being a cooperative member is a significant contributory factor toward an increase in household income. Based on the research findings, several recommendations to improve the households' income are proposed.
