정보기술을 이용하면 도서관의 종이자료가 전자자료로 바뀌면서 기계화 되므로 문헌봉사는 비사서가 하게 되거나 이용자들이 손수봉사(Self-serveice) 하게 된다. 전문 사서는 인간을 대상으로 봉사하게 되므로 인간관계가 중요하게 대두된다. 도서관의 인간관계는 합리적이고 사무적이며 협동하게 되나 상호작용보다는 커뮤니케이션이 강조된다.

첨가제는 기유인 탄소와 수소로 된 유기화합물과 함께 존재하면서 윤활기능을 높여주는 것으로써 유황, 염소와 인을 주요 성분으로 하고 있다. 비록 이들 첨가제의 화학적 구조와 반응에 따라 윤활기능 및 역할을 체계적으로 연구하는 것은 매우 복잡하고 때로는 불가능하지만 가능한 범위에서 화학적 관계와 윤활작용의 상호관계를 살펴보기로 한다.

This study compares blogs of professional reporters with those of citizen reporters in terms of watchdog and interactivity functions. Watchdog function was analyzed in light of the extent of soft news and the degree of critical relationship with the government. Interactivity was assessed by analyzing readers' comments on the articles of reporter blogs. for citizen journalism and for professional one were chosen in order to minimize any discrepancies caused by ideological differences. As a result of the content analyses, citizen reporter blogs were found to deliver soft news more frequently than those of , whereas the former had stronger tendency to maintain the critical relationship with the government than the latter. As for the interactivity function, although the number of comments uploaded to citizen reporter blogs was higher than that of professional reporter blogs, the latter was found to meet the standards of communicative interaction more adequately than the former.

Exploring microRNA (miRNA) and mRNA regulatory interactions may give new insights into diverse biological phenomena. Recently, miRNAs have been discovered as important regulators that play a major role in various cellular processes. Therefore, it is essential to identify functional interactions between miRNAs and mRNAs for understanding the context- dependent activities of miRNAs in complex biological systems. While elucidating complex miRNA-mRNA interactions has been studied with experimental and computational approaches, it is still difficult to infer miRNA-mRNA regulatory modules. Here we present a novel method, termed layered hypernetworks (LHNs), for identifying functional miRNA-mRNA interactions from heterogeneous expression data. In experiments, we apply the LHN model to miRNA and mRNA expression profiles on multiple cancers. The proposed method identifies cancer-specific miRNA-mRNA interactions. We show the biological significance of the discovered miRNA- mRNA interactions.

This study was carried out as a preliminary study to analyze how emotion(depression and anxiety) after spouse bereavement in old age affects social interaction and to set a direction of developing programs based on the cause and period of bereavement to promote social interaction for those bereaved people. To that end, welfare facilities and schools for the elderly and churches located in Seoul, and Suwon and Osan areas were visited and surveys were executed on 350 aged people who had experienced spouse bereavement from September 26 through October 25, 2014. Analysis was executed for 325 questionnaires out of the total of 350 using SPSS WIN 20. Study findings are as follows: first, the average of emotion and social interaction due to bereavement was not significantly different between groups; second, the average of emotion and social interaction due to bereavement period was not significantly different between groups; third, the impact of bereavement type and period statistically significant. These findings implies that social interaction programs for the aged people can be developed regardless of bereavement cause or period.

The goal of this study was to examine the relationship between teachers' efficacy belief and interactions between teachers and children of childcare teachers, and utilize the results as the basic data to educate of teachers. The subjects were 205 teachers at 48 childcare centers located in the Jeonlabukdo area. The results of this study are as follows: First, personal teaching efficacy and factors of interactions between teachers and children were significantly different by the types of childcare institution. Second, personal teaching efficacy was correlated positively with teachers' experiences. General teaching efficacy, personal teaching efficacy and factors of interactions between teachers and children were correlated positively with teachers' age. Third, factors of interactions between teachers and children were correlated positively with personal teaching efficacy. Lastly, personal teaching efficacy was the most powerful variable influencing interactions between teachers and children.

The purpose of this study was to examine the impact of the listening competence of early childhood teachers on their teacher-parent communication difficulties and teacher-child interaction in an attempt to provide some information on the development of the listening competence of early childhood teachers. Three hundred and twenty two early childhood teachers participated in the study and descriptive, correlation, multiple regression analysis were conducted. The results are as follows: First, listening competence had a statistically significant negative correlation with teacher-parent communication difficulties. Second, among the sub-factors of listening competence, comprehending and interpreting, and responding exerted a statistically significant negative influence on teacher-parent communication difficulties. Third, listening competence had a statistically significant positive correlation with teacher-child interaction. Fourth, among the sub-factors of listening competence, responding, comprehending and interpreting, analyzing and evaluating exerted a statistically significant positive influence on teacher-child interaction.

The purpose of the present study is to examine the causal relationship and invest the difference among isolation, interaction, content satisfaction, achievement and persistence in cyber university education by employment status. For this study, 104 students at A cyber university in Korea completed surveys in the fall semester of 2011. The result of this study indicated that there was a meaningful effect of interaction on isolation. Secondly, there was a meaningful effect of interaction on content satisfaction. Thirdly there was a meaningful effect of interaction on achievement. Lastly there were meaningful effects of isolation and interaction on persistence. In addition, according to multi-group analysis, there were no significant differences of structural path coefficients between two groups. Based on these results, this study suggests instructional design methods and management strategies to improve the quality of learning in cyber universities.

This study was aimed to explore the relations between Father's language interaction and self-leadership, preschool adjustment of young children. The subjects consisted of 253 four- and five-years-old children and their father's. Data were analyzed by Pearson's r. The results of study were as follows; First, there were significant correlations between father's language and self-leadership of young children. Second, there were significant correlations between father's language and preschool adjustment of young children. The educational implications of these indicate that we need to actively develop programs to increase self-leadership and preschool adjustment of young children through parents education.

In these days startup became one of the most hot issue in business world. The problem is many startup couldn't overcome the valley of death. For this reason many startup want to funded by venture capital. However startup's business is trade secret itself, so they have to make strategic approach to venture capital. The purpose of study is to find the way to make strategic decision for startup. By analyzing the relation between startup's characteristic and venture capital's investment portfolio. Four famous venture capital(Sequoia capital, Lightspeed venture, Firstround and Khosla venture) and their seed invested startup Dropbox, Airbnb, Snapchat, Uber and Instacart was selected for this study. As a result, each venture capital has their own invest category characteristic and their seed funding belong to their category. Moreover, between seed funded startup and 36,4% of 244 past invented company shown vertical relationship, beside 0.5% of past 244 invested company shown horizontal relationship. This result shown the importance of the relation between startup's characteristic and venture capital's portfolio. Startup have to check the venture capital's portfolio for the strategic approach for funding and venture capital have to make mutual positive portfolio for decreasing the risk.
