The purpose of this study is to examine the influence of the child-mother attachment and the child-father attachment (secure attachment, insecure avoidant and insecure disorganized attachment) on children's mutual friendships and mutual antipathy relations. The subjects consisted of 116 5-6 year old kindergarteners (64 boys & 52 girls) and they were asked to respond to the Attachment Story Completion Task by Bretherton & Cassidy (1990), based on the sociometric popularity postulated by Coie & Dodge (1988). Data were analyzed by the logistic regression analysis and the one-way ANOVA method and the Scheffe test in multiple comparisons analysis. The results concluded that 1)There were differences in terms of child-mother attachment and child-father attachment when it came to a child's mutual friendship. The secure child-mother and child-father attachment groups had more mutual friendships than the insecure attachment groups. 2)There were no differences in terms of child-mother attachment and child-father attachment when it came to child's mutual antipathy. 3) 78.0% of the mutual friendships were accurately classified as existence with respect to child-mother and child-father attachment.

The emergence of social media and technical development of smart phone allows media users to produce, share and spread a variety of contents, which results in a big change in their media usage pattern. Among those changes, the most prominent one is Youtube's powerful growth. Creators' enthusiastic content productions and users' active sharing actions are caused of the growth. Recently, creators give a powerful effect on users as social media influencer, and the practice of influencer marketing has been focused. This current study is examined the effects of parasocial interaction and relationship on brand attitude and purchase intention. Specially, parasical interaction is divided into identification, interest, and experience parasocial interaction, and the divisions of relationship are trustworthy, friendship, understanding, and commitment. As a result, interest and trustworthy are significant predictors of brand attitude. Also, experience parasocial interaction is negative and friendship is positive predictors of purchase intention. Theoretical and practical implication are discussed.

This primary purpose of this study is to suggest alternatives for raising the Korea Post as a global logistics firm using a case study. The following alternatives for raising the Korea Post as a global logistics are suggested. First, as a first stage, in addition to previously established business scope such as saving, mail, insurance, logistics business unit have to be added. Second, as a second stage, warehousing and multimodal transport logistics have to be strengthened through M&A or self-financing and investment. Third, as a third stage, market coverage and service scope is to be expanded to country having larger logistics market size. Finally, as a fourth stage, global-oriented total logistics service is to be provided.

연안해역은 육상환경과 해양환경이 상호작용하는 완충지역으로서, 양식어장, 항만, 해수욕장 등으로 이용되고 있다. 남해안과 같은 연안해역은 기초생산력이 아주 높고, 해면양식업에 적합한 지형적 여건을 갖추고 있어 옛부터 어패류 양식장으로 널리 이용되고 있다. 연안환경 특성에 따라 크게 2가지 유형 즉, 진해만과 같이 외부 부하량 증가로 적조가 상습적으로 발생하는 부영양화된 해역, 한산ㆍ거제만과 같이 외부 부하량 유입이 적고 기초생산력이 낮은 빈영양 해역으로 나누어진다. (중략)

This study was conducted to pursue Christian education with the socially underprivileged in the era of the Corona-19 pandemic. Corona-19 is a disaster which is caused, destroyed and exploited by human being. At the time of the indiscriminately spreading global pendemic, we must work together to overcome our selfish self-centeredness and make an attempt for everyone in need. It is a study on how humans can help each other survive in the era of Corona-19 and its post-corona. The problem is that there is too much discrimination between the state, race, and economic capacity, and in the end, the extreme discrimination of capitalism is appeared in society and across the country. There is no significant difference in the confirmation rate when Corona-19 infiltrates, but there is a big difference between those with and less in mortality. As a result, today's reality is that people who have a hard time living because they have less usually are far more vulnerable to blocking and defeating virus attacks. Unfortunately, this is the current situation. From the standpoint of a large discourse, attention is paid to climate change and ecological environment, and as a micro discourse, a number of societies who live with tremendous discrimination according to the gap between the rich and the poor (it is gender, race, disabled, nationality) that exist in almost all countries on the planet. We need attention to the weak. To this end, discourses on vaccine inequality, discourses on the needs of the disabled, discourses on different racial damages, discourses on polarization and dystopia, and discourses on educational inequality were treated as the reality faced by the socially underprivileged in the Corona 19 pandemic. To explore Christian education with the socially underprivileged, to explore ways of sharing, giving, and solidarity for win-win, discourse on inter-dependence and mutual responsibility of mankind, direct counter-measures for the socially underprivileged, and critical literacy education. He proposed a discourse on Korea, a discourse on Homo sapiens, which must return to being a part of creation, and finally a theology of friendship with the weak. Christian education based on Bible words must go forward in the era of the Corona 19 pandemic, hungry, naked, nowhere to go, sick, but dying because of being unable to get a remedy. He emphasized the need to establish a caring theology of friendship and pursue a life in which thought and practice harmonize. Thus, the paper proposed the spirit of Christian education not only doing something for the socially weak, but with the socially weak in the daily life.

Slow sand filtration processes amended with 5 and 10cm GAC layers at top was compared to same process at bottom in a pilot study for humic substances removal. In case of 5cm GAC layer, the process amended at bottom was superior to the process at top in DOC and UV254nm removal and same trends were observed in case of 10cm GAC layer. Head loss developments of the process GAC at bottom were higher than the process GAC at top so that maintenance of the process GAC at top is easier than the process GAC at bottom.

This paper identifies the determinants of adoption and diffusion of e-government services, and examines the causal relationship among the variables of adoption behavior. The main findings, based upon survey responses from service users, are as follows: first, both the value of service and the socially influencing factor have the positive effect to the intention of utilizing services. Second, the socially influencing factor has the indirect effect to the intention of utilizing services, because it positively affects the value of service. The interaction factors, however, do not directly affect the intention of utilizing services. These interaction factors indirectly affect the intention of utilizing services through the path which increases the value of service, and its effect is larger than the socially influencing factor.

New technologies are providing unprecedented knowledge into microbial community structure and functions. Even though nucleic acid based approaches provide a lot of information, metaproteomics could provide a high-resolution representation of genotypic and phenotypic traits of distinct microbial communities. Analyzing the metagenome from different microbial ecosystems, metaproteomics has been applied to seawater, human guts, activated sludge, acid mine drainage biofilm, and soil. Although these studies employed different approaches, they elucidated that metaproteomics could provide a link among microbial community structure, function, physiology, interaction, ecology, and evolution. These approaches are reviewed here to help gain insights into the function of microbial community in ecosystems.
