Purpose: This study was done to identify the effects of the Positive Peer Relationship Training Program on self-esteem, bullying, and depression. Methods: The research design was a quasi-experimental research with a nonequivalent control group non-synchronized pre-posttest. The recruited participants were forty-four 6th graders at an elementary school in G city. The research was carried out from September 10 to November 19, 2012. To test the effects of the Positive Peer Relationship Training Program, the participants were divided into two groups, an experimental group (23) and a control group (21). The Positive Peer Relationship Training Program was provided to the experiment group for 45 minutes/session twice a week, for 4 weeks. Data were analyzed using Fisher's exact probability test, $x^2$-test and t-test with the SPSS/WIN 18.0 program. Results: After attending the Positive Peer Relationship Training Program, no significant differences were found in self-esteem scores but significant differences were found in bullying and depression scores between the experimental group and the control group (t=1.27, p=.212, t=-2.10, p=.042; t=-2.37, p=.023). Conclusion: The results indicate that the Positive Peer Relationship Training Program is an effective nursing intervention for decreasing bullying and depression among Children in Early Adolescence.

Recently, the initiation of outside diameter stress corrosion cracking (ODSCC) at the tube support plate region of domestic steam generators (SG) with Alloy600 HTMA tubes has been increasing. As a result, SGs with Alloy600 HTMA tubes must be replaced early or are scheduled to be replaced prior to their designed lifetime. ODSCC is one of the biggest threats to the integrity of SG tubes. Therefore, the accurate evaluation of tube integrity to determine ODSCC is needed. Eddy current testing (ECT) is conducted periodically, and its results could be input as parameters for evaluating the integrity of SG tubes. The reliability of an ECT inspection system depends on the performance of the inspection technique and abilty of the analyst. The detection probability and ECT sizing error of degradation are considered to be the performance indices of a nondestructive evaluation (NDE) system. This paper introduces an optimized evaluation method for ECT, as well as the sizing error, including the analyst performance. This study was based on the results of a round robin program in which 10 inspection analysts from 5 different companies participated. The analysis of ECT sizing results was performed using a linear regression model relating the true defect size data to the measured ECT size data.

ICT convergence using smart livestock is that in the first-generation dairy smart farm model, each device made by several manufacturers uses its own communication method, limiting the mutual operation of each device. This study uses a model based on open control technology to secure interoperability of existing ICT devices and to manage data efficiently. The open integrated control derived from this process is the software interface structure of Open API. It is an observer that serves as real-time data collection according to the communication method of ICT devices and sensors located at each end. It consists of a broker that connects and transmits to the upper integrated management server. As a result of the performance analysis through verification of two first-generation dairy smart farm model sites, the average daily milk production increased compared to the previous year (farm A 5.13%, farm B 1.33%, p<0.05). Cow days open (DO) was reduced by 17.5% on farm A and 13.3% for farm B(p<0.05). Cows require an adaptation period after the introduction of the ICT device, but if continuous effects are observed, the effect of production can be expected to increase gradually.

The purpose of this study is to identify characteristics of secondary school teachers' perceptions and experiences of school libraries and to suggest strategies for its' activation. In order to achieve this aim, the questionnaire survey was conducted for 229 secondary school teachers who participated in K university qualification training in 2017. As a result, they recognize that school libraries are an essential facility and that continuous support and investment are needed. They think that the effectiveness of the school library is very helpful for creating a leisure and cultural life and for stimulating reading atmosphere and education, and this perception is stronger at lower ages. The number of school library use of them is as low as once a month, and the purpose of use is mainly for cultivation and leisure. The discomfort of the school library is mostly due to lack of materials and space for them. In particular, they have a lack of knowledge and necessity about the method of library-based instruction and insufficient preparation time and poor materials. Teachers are highly aware of the need and utility of training, and prefer training with peers. Therefore, it is necessary to develop strategies such as remodeling space and increasing collections for their study and instruction, and foster peer supervision so that they can actively utilize school library in subjects management.

Online discussion bulletin in Korea is not only a specific place where user exchange opinions but also a public sphere through which users discuss and form public opinion. Sometimes, there is a heated debate on a topic and any article becomes a political or sociological issue. In this paper, we propose how to analyze the popularity of articles by collecting the information of articles obtained from two well-known discussion forums such as AGORA and SEOPRISE. And we propose a prediction model for the article popularity by applying the characteristics of subject articles. Our experiment shown that the popularity of 87.52% articles have been saturated within a day after the submission in AGORA, but the popularity of 39% articles is growing after 4 days passed in SEOPRISE. And we observed that there is a low correlation between the period of popularity and the hit count. The steady increase of the hit count of an article does not necessarily imply the final hit count of the article at the saturation point is so high. In this paper, we newly propose a new prediction model called 'baseline'. We evaluated the predictability for popular articles using three models (SVM, similar matching and baseline). Through the results of performance evaluation, we observed that SVM model is the best in F-measure and precision, but baseline is the best in running time.

This paper investigates the effects of public R&D support on medium-sized firms' R&D investment. The paper collects a panel dataset of Korean manufacturing firms' R&D investment and public support, and employs the DID (difference-in-differences) regression for the test of stimulating or crowding-out effect. Empirical analysis examines how the effect of public R&D support differs between small and medium-sized firms and whether firm size and technological capability moderate the effect in the sample of medium-sized firms. Empirical results show that public R&D support tends to generally stimulate private pure R&D investment for both small and medium-sized firms. Comparing the results for small and medium-sized firms, this paper finds that the stimulating effect is relatively larger and more significant for medium-sized firms, while the effect is not significant for small ones. Furthermore, the paper shows that the stimulating effect of public R&D subsidy on private R&D investment is relatively stronger for medium-sized firms with superior technological competence and the effect of tax support is greater for incompetent firms. These results suggest that public R&D policies and R&D programs, differentiated from those for existing small firms, are necessary for medium-sized firms to stimulate private R&D continuously and formulated carefully by considering firm size, technological capability and growth potential.

The aim of this paper is to describe a long-term trend toward earlier retirement and its reversal since 1985 in the United States, together with changes in socioeconomic conditions and social-policy programs which have contributed to this new development. The American people's recent propensity to retire at relatively younger ages was mainly a result of secular increase in individual wealth that had made it possible for them to enjoy higher standard of living without their participation in labor market activities at older ages. In addition to the introduction of compulsory retirement system, both social security retirement pension program and corporate pension system have also contributed significantly to the declining retirement age and its reversal around the mid-1980s. This paper pays full attention to the set of social policy programs which are currently being used to sustain the recent reversal in ages at retirement. The basic question to be raised here, however, is about whether or not the U. S. government will ave to continue to implement the social policies and programs used to discourage the elderly from retiring at relatively younger ages in the future. In this paper, it is argued that labor productivity growth and improvement in work attitude prior to retirement will help the elderly find little difficulties in having higher standard of living, despite their further lengthening of life expectancy at birth and post-retirement survival chances, the latter being often called the "third life". Most American people hope that the social-policy programs that have promoted early retirement will remain unchanged in the first part of the 21st century while they will put significant financial burden on their future descendants who have to work in the paid labor market. Taking this observation in consideration, this paper concludes that the U. S. government has to focus more on developing the programs that improve work propensity and labor productivity among the currently working-age population rather than continuing to implement the programs that sustain the recent reversal in retirement ages.ment ages.

This study was a descriptive investigation of the effects of nursing students' major satisfaction and professor-student interaction on their adjustment to university life. For this investigation, data were collected from July 22 to August 15, 2017. The collection was made through a questionnaire survey of nursing students in their 1st or 2nd year at one of eight colleges or universities located in B Metropolitan City, U Metropolitan City and G City. Participants were informed of the purpose of the study and agreed to participate in it. Of all the questionnaire sheets collected after the survey, those filled in by 205 participants were finally used for analysis here, with those by others excluded because they were considered to have been inappropriately filled out. The findings of this study can be summarized as follows. Nursing students surveyed in the study were significantly different from one another with respect to adjustment to university life depending on grade, health status, interpersonal relationships, desired career, academic achievement and family life level. Moreover, nursing students who had higher satisfaction with their major and more interactions with their professors were likely to adjust better to university life. In addition, regression analysis revealed that the nursing students' satisfaction with their major had the biggest effect on their adjustment to university life. Taken together, the results suggest that nursing students in their 1st or 2nd year of school should continue to be provided with curricular or extracurricular programs designed to improve their major satisfaction and that they should be given opportunities for communication with or counseling from their advisors or other nursing professors from the onset of university life.
