The purpose of this study was to identify bibliographic characteristics of the top level articles among KCI indexed academic articles. Unlike the existing analysis on citation and most-cited articles, this study analyzed their bibliographic characteristics. The 3,453 articles were collected from 17 social science fields in KCI. The characteristics of authors, institutions, publications, journals, and citations were analyzed. According to the result of the analysis, there was a difference in the ratio of single authors to co-authors and in the number of co-authors. The authors were mostly single authors or two co-authors. In general, the percentage of authors of one article was high. Second, the types of institutions were mostly universities, and there were differences in the number of institutions with authors in each field. And the frequency of the authors' affiliation appeared uneven. There were a number of excellent research institutes and authors depending on the field. Third, the average of years to take to become the top articles for publication was 11 years in 2018. Fourth, most of the published journals were KCI registered journals, and the influence of the journals was not a factor. Fifth, there were differences in the number of cited counts between fields. This study is meaningful to grasp the influencing factors on the bibliographic characteristics of the most-cited articles for the social science field.

The purpose of this study is to analyze the effects of government's R&D investment outcome on the IT industry. The analysis of R&D investment outcome developed emphasizing qualitative outcome more than quantitative outcome. However, it is still leaning on technological outcome-centered methods, having relatively little interest in inputs that actually determine the outcome. Thus, this study intends to focus on the qualitative attributes of input resources. The results of the empirical analysis can be summarized as follows. In raising technological outcome and commercialization outcome of R&D investment, more funds per researcher and numbers of researchers and a longer development period had positive effects. However, a higher ratio of doctors had positive effects only on technological outcome (papers and patents), It is believed that leading to commercialization outcome needed a long period, but the period of task development was only an average of two years. On the contrary, collaboration had negative effects on technological process, which indicates that collaboration between two organizations having conflicting interests would lead to negative effects on the outcome. The results show that the qualitative attributes of input resources have significant effects on R&D investment outcome, and imply that it is necessary to emphasize the qualitative attributes from the input stage to promote government's R&D investment outcome in the future.

This study was conducted to determine the impacts of perceived stress and empathy ability on altruistic behavior of freshman nursing students. Data were collected from 160 freshman nursing students between 24 November and 9 December 2016. A total of 154 questionnaires were analyzed using descriptive statistics, t-tests, one-way ANOVA, Pearson's correlation coefficient, and Stepwise multiple regression. The results showed that perceived stress had significant negative correlations with altruistic behavior (r=-0.178, p=0.028) as did positive perception, a subfactor of perceived stress (r=-0.347, p<0.001). However, empathy ability was significantly positively correlated with altruistic behavior (r=0.607, p<0.001). The factors influencing altruistic behavior included emotional empathy, cognitive empathy and positive perception, with emotional empathy being the most influential factor (${\beta}=0.320$), followed by cognitive empathy (${\beta}=0.312$), which together had an explanatory power of 41.6%. Moreover, there was a mediating effect of empathy ability in the relationship between positive perception and altruistic behavior. Overall, the results of this study indicate that the management of curricula for nursing college students should search for ways to reduce their perceived stress as well as increase their empathy ability in order to improve their altruistic behavior.

Due to the industrial development and population growth, it has recently been shown that there are many problems caused by the rinked treatment water in local goverments and sewage treatment plants. The rinked treatment water has a characteristic of low flow rate and high concentration unlike general sewage. These characteristics increase sewage treatment difficulty and sewage treatment fee of sewage treatment facilities. Among the many influencing factors that increase sewage treatment unit cost, 'linked treatment load/design inflow load (%)' was derived as the most correlated factor. Through the selection and modeling of sewage treatment plants, the excess scope of design discharge water quality was investigated under the conditions of temperature and the conditions of 'linked treatment load/design inflow load (%)' taking into account the effects of the four seasons. The study found that for TN, 'linked treatment load/design inflow load (%)' was 19.7%, 22.6%, 25.1%and 27.7%, respectively, under conditions of $5^{\circ}C$, $10^{\circ}C$, $20^{\circ}C$ and $25^{\circ}C$. In case of TP, 'rinked treatment load/design inflow load (%)' was 10.7%, 12.2%, 15.6% and 17.5% at $5^{\circ}C$, $10^{\circ}C$, $20^{\circ}C$, and $25^{\circ}C$, respectively, under conditions of $5^{\circ}C$, $10^{\circ}C$, $20^{\circ}C$ and $25^{\circ}C$.

This study aims to explore the influencing factors and the process of enhancing science self-efficacy (SSE) and to lay the foundation in understanding science self-efficacy of students. The ten categories related to the science self-efficacy were derived through the coding of the interview data based on the grounded theory and paradigm analysis to develop a process model of science self-efficacy improvement. Through the process analysis, four cyclical phases were found in the process of enhancing SSE: 'Entering into learning science' phase, 'enhancing SSE' phase, 'adjustment' phase, and 'result' phase. More specifically, the phase of 'entering into learning science' is where students choose science track and stimulated to construct SSE. The phase of 'enhancing SSE' is where students taking a science track actively learn science and perform science activities. In the phase of 'adjustment', students come to have successful performance about learning science and performing science activities by using diverse strategies. Finally, 'result' phase indicates different appearances of students depending on SSE levels. The phases were non-linear and periodically repeat depending on situation. The core category in the selective coding was indicated to be 'enhancing science self-efficacy.' Students' SSE form by learning science and performing science activities. These finding may help better understand the behavior of students who are taking a science track by facilitating effective science learning through the increase of their SSE levels.

The purpose of this study was to investigate the relationship between demographic characteristics, self - esteem, and attachment instability (attachment anxiety, attachment avoidance) in the college students' SNS addiction tendency. To investigate the influencing factors on SNS addiction tendency of college students, we surveyed 330 college students at universities in the metropolitan area through offline and online questionnaires, and analyzed 271 valid ones. Frequency analysis, descriptive statistics, variance analysis, Pearson correlation analysis and multiple regression analysis were performed. The results of the analysis are as follows. First, 87.4% of college students used SNS, and the most used SNS was 'Facebook (82.3%)'. The most frequent use of SNS per day was 'over 1 hour ~ less than 2 hours (24.7%)'. Second, women had a significantly higher SNS addiction tendency than men. Third, self-esteem and SNS addiction tendency showed significant negative correlation. Fourth, attachment anxiety and attachment avoidance were positively correlated with SNS addiction tendency. Fifth, the self-esteem of college students affects negatively on the SNS addiction tendency and only the attachment anxiety among attachment instability affects the addiction tendency. Finally, we discussed the risk of SNS addiction according to the characteristics of university students.

The purpose of this study is to investigate the lifestyle factors influencing behavioral problems such as Inattention, hyperactivity/impulsivity, and internet overuse in elementary and middle school students. Data from 889 elementary school students and 676 middle school students were used and teacher reporting on students' attention deficit and hyperactivity and impulsivity symptoms was also included in the analysis. Lifestyle included opportunities for family interaction, sleep, watching TV, playing Video games, eating breakfast, eating junk food, and private education. As a result of stepwise regression analysis, Video games, junk foods, and family interactions significantly predicted the inattention of elementary and middle school students. Video games, TV, junk foods, and family interactions significantly predicted elementary school students' hyperactivity and impulsivity, but the lifestyle variables hardly accounted for the hyperactivity/impulsivity of middle school students. Video game, and family interactions significantly predicted Internet overuse for both elementary and middle school students. Current study suggest that family interaction opportunities and the use of video games, TV and junk food should be considered to intervene in behavior problems.

This study examines 2014 National Survey on Older Koreans (10,279 persons aged 65 or above) to understand social networks among older Koreans. In order to classify the types of social relationships, the latent profile analysis is conducted based on such structural aspects of social networks as network size, frequencies of contact, and closeness. The results show that older Koreans can be categorized into 5 distinct social network types: disengaged (11.6%), ritual-family-focused (17.7%), close-family-focused (23.6%), close-restricted (28,4%), and diverse (18.8%). Characteristics by each social network type are compared and multinominal logistic regression analyses are applied to figure out the influencing factors of social network type. Older persons with disengaged social network ties tend to be overwhelmingly female, living alone, old-old, and of low socioeconomic status. On the other hand, older persons with diverse social network ties tend to be young-old and had highly-ranked jobs in their mid-life. Spouse/children are the focal point of social relationships in both ritual-family-focused and close-restricted social network. However, the proportion of men is higher in the close-family-focused type than in the ritual-family-focused. Older Koreans with close-restricted social network ties tend to be female, uneducated, and have engaged in agricultural and allied activities. This study discusses the implications of its findings and how research in this area should develop in the future.
