The purpose of this paper is to investigate characteristics of active information and opinion giver in the interactive-public communication space of internet. More specifically, this study explores that the active information and opinion giver have the same traits with opinion leader, which are personal attributes (topic involvement and individuation), social activity, source of information and influentials, and socio-demographic attributes. The research consisted of a questionnaire, which was administered using e-mail, and 175 replies were returned. The results show that higher activity of sending information and opinion is associated with characteristics of opinion leader. First, It was found that higher activity group in sending information and opinion have higher degree of topic involvement and individuation than lower group. Second, the former is more active behavior than the latter in social activity. Third, it was examined that behaviors of sending and giving information and opinion with interpersonal communication channel was connected with those of the interactive-public communication space in internet. Also, the result of analysis with mass communication channel was found the distinction in three different kinds of magazines which is related with specific media.

This paper investigate the problems of standard container port handling capacity in establishing national port development plan in Korea. Considering container port developing, it's not easy to adopt container port service quality parameters such as lay time constraint of very large container ships by using the standard guideline of container port handling capacity. A simple methodology that connects vessel waiting to service time(w/s) and berth occupancy to costs has been used to evaluate the performance of a container terminal. But the total handling capacity have to be calculated by the performance of the handling system and number of equipments and layout of terminal by using computer simulation that represents of reality events needs to be performed by probabilistic techniques. A simulation model of estimation of container terminal capacity is introduced in order to establish a hub terminal for very large container ships that focus the port's quality of service and also suggest as tool for policy maker to justify a required port investment.

The present study grasped the operation characteristics and operation management of forest museums in Korea and analyzed satisfaction with the foregoing. In the results of a survey of forest museums' operation characteristics, with regard to groups to which exhibits were helpful, over half of respondents answered that the exhibits were helpful to students and many respondents had an opinion that all age groups should be equally considered as targets of exhibition. Among matters that were considered with regards to forest museums, accessibility showed the highest rate of answers followed by museum programs. The curator was needed for the majority of respondents were exhibits prior to the survey had the highest expectations for the medium. With regard to the operation management of forest museums, the expected value of periodic and extraordinary exhibitions was shown to be high and high and satisfaction was shown by the professionalism of staff. As for matters of forest museums that must be improved, attention should be paid to the development of programs in which users can participate, diverse exhibition media should be developed, and exhibition should be planned to fit the composition of exhibits. As for operation management, since exhibits were repeated every year, environments should be changed by exhibiting new exhibits or otherwise and active methods of improvement should be devised such as the utilization of broadcasting media for public relations.

The aim of this paper is to develop a performance evaluation model for PPP (Public-Private Partnership) projects that appropriately reflects the important traits that are unique to PPP projects. To this end, 1) it defines a set of distinct perspectives involved in the PPP projects and their associated success factors that might differ amongst the perspectives; 2) it identifies the key performance indicators and suggests the performance evaluation criteria for each indicator; and 3) it builds a performance evaluation model by matching the success factors from each perspective with performance measure criteria as well as applies the model to the two selected BTO road projects in Korea. The process of model construction and its application confirms significant differences between the main stakeholder perspectives typically involved in PPP projects, which highlights the need for an evaluation model tailored for PPP projects by taking into account the distinct perspectives. The results from the PPP evaluation model developed in the study is compared against the results from the existing ex-post evaluation model for construction projects in general. The former shows a closer match with the results from the user satisfaction survey conducted. This new evaluation framework and the performance indicators entailed in it permits a balanced evaluation of PPP projects as it takes into account different perspectives involved in PPP projects as well as an understanding of the factors affecting the success of PPP projects. While the construction of the model is based on transport projects, it is applicable to different types of PPP projects through variation with the weight allocation amongst different success factors and/or additions or other adjustments to the performance evaluation criteria as required.

Since the Child Friendly Cities Initiative(CFCI), a UNICEF-led initiative, was first introduced to Seongbuk-gu in 2013, more than half of the districts of Seoul are making efforts to achieve the accreditation of the Child Friendly City(CFC). At this point, when an initiative is transformed from a special policy of a few districts into a general policy of many local governments, we need to examine and check on how friendly urban parks are to children. This study focused on neighborhood parks that tend to be less friendly to children as compared to children's parks and looked into the current status, because neighborhood parks are also well used by users of all ages including children. The evaluation criteria was developed based on the review of domestic and international guidelines of child friendly parks and neighborhood parks. Futhermore, field studies, user questionnaire, and a participatory design workshop were introduced to analyze the status of child-friendly environment of neighborhood parks. Findings are as follows. First, vague definitions of child cause the inconsistency of child-related policies. Second, Neighborhood parks are not conceived as a public space for children. Third, the consideration of youth is relatively low. Fourth, adjacent area of a park turns out not to be child friendly as well.

This study aims to examine the relation between opinion perception and opinion expression by issue types by analyzing online poll results and respective bulletin boards. To find out how opinion poll results affect the public opinion perception cues and opinion expression through the internet, the study applied a method of content analysis to the online contents provided by Naver.com, one of the most popular portal sites in Korea. A total of four issue types, along with 2,250 messages were chosen for analysis. The study results revealed that internet users perceived opinion atmosphere through the poll results and expressed their opinions depending on the issue types. In case of an issue where majority views are manifested as online poll results, users tended to follow that majority views by retaining their initial opinion. Majority opinion by the poll results held a dominant position in bulletin board. The results partially support Noelle-Neuman(1994)'s spiral of silence theory in the context of computer-mediated communication contrary to the belief that anonymity in the cyberspace tends to encourage participation of minority opinion group. According to the findings, people when they perceive their opinion as that of minority are discouraged to express their views even when they are online.

The purpose of this study is to examine whether the effect of service satisfaction regarding the accessibility of child care services varies between dual-earner and single-earner families. In particular, we conducted the analysis by dividing the service accessibility into sub-areas. The study sample consisted of 267 parents living in Seoul and Gyeonggi region. As a result of the analysis, accommodation in use time and affordability influenced satisfaction in the single-earner families, and information acquisition and acceptability in the dual-earner families. For single-earner families, the more convenient the use time of the childcare institution and the less the service cost burden, the higher the satisfaction. The dual-earner families had higher satisfaction levels if it was easier to obtain information about the childcare centers and weaker the religious characteristics of the childcare centers. Based on the research results, it is necessary to differentiate the burden of cost and provide more flexible operation of childcare service operating hours. In addition, it is necessary to devise a policy method to increase the transparency of information to childcare institutions.

This study reconsiders the concept of publicness by raising a question about the problems which the recent marketization of social services in South Korea. The existing perspective on publicness, however, is insufficient to account for the entire Long-term care market because only public organizations have publicness. Accordingly, this study presents 'integrated publicness', particularly 'dimensional publicness' and 'normative publicness'. A disproportional stratified sampling procedure was used to consider ownership. A merged dataset combining surveys from 248 Long-term Care facilities and on-line resources was used and analyzed by multiple regression, negative binomial regression and multiple imputation analysis. The analysis results suggest as follows. First, ownership publicness appeared more effective in the overall. Second, the regulations on the government funding did not show effective, and the regulation on evaluation system showed the effect. Third, professionalization of normative publicness showed a negative effect on service structure and showed a positive effect on service process. Lastly, user of free services whose public accountability was identified to be effective on service structure and outcome. These findings suggest that not only existing ownership but also dimensional publicness and normative publicness showed an effect on service quality. In this respect, this is important as the performance produced by empirical models of integrated publicness, in this situation that the outcome of marketization is insignificant.

This paper consists of two parts: In the first part, we describe our work to build hierarchical knowledge base of digital library patron's research interests and learning topics in various scholarly areas through analyzing well classified Electronic Theses and Dissertations (ETDs) of NDLTD Union catalog. Journal articles from ACM Transactions and conference web sites of computing areas also are added in the analysis to specialize computing fields. This hierarchical knowledge base would be a useful tool for many social computing and information service applications, such as personalization, recommender system, text mining, technology opportunity mining, information visualization, and so on. In the second part, we compare four grouping algorithms to select best one for our data mining researches by testing each one with the hierarchical knowledge base we described in the first part. From these two studies, we intent to show traditional verification methods for social community miming researches, based on interviewing and answering questionnaires, which are expensive, slow, and privacy threatening, can be replaced with systematic, consistent, fast, and privacy protecting methods by using our suggested hierarchical knowledge base.
