  • This study was conducted to test the green-tide mitigation technique in the lower part of the Sook Stream (Chusori) of Daecheong Reservoir from June 27 to August 24, 2014. And the effects were compared with weekly monitoring result of the watching station of the algae alert system (AAS) as well as test beds reach. The green-tide in a test bed was begun from the upstream, and it was gradually transferred and spread toward the downstream by the hydrological factors. The total amount of algae removed by algae removal device during the test period was 33,920 kg, and solids dewatered by natural gravity was 8,480 kg. Also chlorophyll-a content was 2.83 kg, the number of blue-green algae cells was equivalent to $78.6{\times}10^{14}$ cells. Compared with the results of the watching station of AAS, the pre-concentrate removal work in the outbreak waters was able to suggest the possibility of green-tide mitigation. In addition, an effective management of the green-tide was required spatial and temporal occurrence information and practical device technology. Particularly, the optimal timing of algae removal in the river-reservoir hybrid system was recommended at times before the monsoon rainy season and reached the lowest water level.

  • It is crucial In decision making to select a project delivery system (PDS) adjusted accordingly to the project characteristics. Furthermore, selecting a tendering system is the kernel in the process of selecting PDS. In October 2007, the Ministry of Finance and the Economy of Korea launched two new project delivery systems, "Best Value Contract (Design-Bid-Build)" and "Bridging Contracts (Design-Build)" by revising enforcement ordinances of "Act on Contracts to Which the State is a Party" to provoke the tendering systems. In order to support the proposed purpose, this research developed a selection model for suitable tendering system, which helps a public owner select a tendering system appropriate to the project characteristics. First, the framework of the model was set throughout analyzing previous researches and interviewing relevant experts. Additionally, by analyzing the survey result from 265 experts engaged in architectural and civil engineering business, the relative weights of the selection factors and the effectiveness values of the alternatives were suggested as the quantitative evaluation references. Finally, the practical guideline was suggested to apply this model to three public projects scheduled to be delivered. The result of applying the model to three case projects showed that further researches were needed to make the selection process logical and to suggest the standard weights and effectiveness values according to project type.

  • The promotion of social economy is one of the Korean government's top 100 initiatives. As of August 2019, there are 2,249 certified social enterprises in Korea, showing explosive growth with a 41-fold increase from 2007 when the Social Enterprise Promotion Act was first enacted. Currently, the discussion of the sustainability of social-economic organizations is lively, including the issue of changing the certification system to the registration system. Noting the unusual management structure of social enterprise - seeking both social and economic value, this study identifies factors affecting the performance of social enterprises. The study focuses on an empirical investigation of the relationships between characteristics of entrepreneurs' experiences in social economy, strategic competency, the extent to which they seek social value, and their performance. This study is unique in social enterprise research due to its approach to the hybrid management structure of social enterprise with a focus on entrepreneurs' characteristics. Accordingly, this empirical investigation focuses on how social-value seeking mediates the relationships between strategic competency emphasized in typical for-profit enterprises, the characteristics of experiences stressed in social-economic organizations, and the performance of social enterprises. The study findings suggest that, firstly, social entrepreneurs must seek social value as a top priority and improve economic performance using strategic competency to keep pursuing social value, and secondly, social-value seeking must be founded upon entrepreneurs' understanding and experiences in social economy. Practical implications of the study findings include concrete directions for training in social enterprises offered by relevant agencies and the establishment of competency models for current and future entrepreneurs.

  • This study was conducted to evaluate the characteristics of nonpoint source pollutants discharge from a small rural watershed. A typical rural area in Gongju City, Korea, was selected as the research site. Water quality and quantity in streams and rainfall samples were analyzed periodically from May to October 2005. Pollutant loads were estimated from a nonpoint source pollution model (AvSWAT, Arcview Soil and Water Assessment Tool). During the rainy season, from June 26 to 30 September 2005 and the dry season, before 26 June and after 30 September 2005, biological oxygen demands and chemical oxygen demands accounted for 91.3% and 93.7% of annual load, respectively, while total-N and total-P were 97.1% and 91.1% of annual load, respectively. The observed stream flow was $66.5m^3sec^{-1}$, while simulation stream flow was $66.2m^3sec^{-1}$. That can be assumed that simulation can be used to estimate the stream flow without practical measurement. However, the runoff trend following the occurrence of a storm event was not recorded properly.

  • The purpose of this study was to provide information on adoptive families and obtain the basis data for adoption-related programs that are useful to adoptive families by examining their experiences in the adoption process, post-adoption adaptation, and adoption programs. For the study, in-depth interviews were conducted on six mothers who publicly adopted elementary school children and had expressed high satisfaction with adopted families and their willingness to participate in this research voluntarily. The main results exhibited parents' happiness post-adoption along with positive changes, such as internal growth, marital love growth, favorable response from others, and child's unexpected responses to adoption. However, open adoption mothers have coped with efforts to sympathize with and accept their children's feelings as they suffer from adoption, and with active support from their spouses, parents, and their own children. Open adoption mothers participated in various adoption-related programs, support, and voluntary self-help groups provided by adoption agencies or public organizations, and above all, their experience in self-help groups and peer groups of adopted children was found to be very useful. Based on these main results, we suggested strengthening welfare services for open adoption families, implementing education to better understand adoption, education for school teachers, students, and welfare staff, providing practical programs for adoptive families, and promoting self-help groups.

  • This article explores how to incorporate the topic of the global environmental crisis called the "anthropocene" into archives studies and connect it to ecological practical reasons. In order to encourage discussion of archival studies, which puts the environmental crisis at a kind of archive constant value, this study seeks to examine the possibility of a quality shift in archival studies based on ecology. This article aims to go beyond the pragmatism of preparing improvements to eco-friendly record management, which is recently claimed by the "Green Archive" in Western archival studies. It calls for a new concept called 'ecological archive', which theoretically combines a more archives-based and ecological paradigm, and its epistemological transformation. Specifically, the ecological approach of archives is first discovered in the discussion of archival studies and at the same time, through the "ecological turn" of archives emphasized by recent anthropocene discourses, the concept of "ecological archive" emphasized by this article is embodied. This study uses 'ecological archive' as a universal and theoretical framework for archives as a basic concept for building ecological 'living' archives. In other words, for the construction of ecological archives, we reinterpret and extend so-called democratic values for archives, i.e., post-custodianship, community archives, and archives of emotions. Finally, the records of foot-and-mouth disease killing burial sites, an important site and example of the anthropocene tragedy, exemplifies the methodology of the actual application of ecological living archives. The case analysis aims to seek a new qualitative shift in record management that adapts to global ecological transformation, while also emphasizing the documentation by archival activism in ecological field practices jointly organized by archivists and citizens.

  • The purpose of this study was to examine the current status of the Dream Start program from the perspective of social investment strategy, and as well as to suggest future directions. The program has become a major government welfare program in korea since it was introduced in 2007 as a demonstration project, following research evidence and a sound rationale about the extensive success of Head Start in the U.S. and Sure Start Programme in the UK. The aim of Dream Start is to provide integrated services for the vulnerable children, aged 0 to 12, and their families who are identified using a national administration data record of disadvantaged families with children. In order to promote the vulnerable child's well-being, to overcome inequalities, and to give every child the best start in life, Dream Start adopted a local, "whole family" approach. Case management services form an essential part of the Dream Start to customize and integrate comprehensive services such as counseling, health care, parenting advice and education, academic tutoring, and after-school activities. Although there has been a general improvement in key factors since its inception, Dream Start has not yet sufficiently shown the strong and hoped-for impact. In the meantime, Dream Start must be given financial expansion and extensive policy supports to get the chance of realizing and evaluating long-term gains for children and their families. More work need to be done to overcome inequalities and to make Dream Start service more accessible for the most disadvantaged families with children in Korea. Practical and policy suggestions for future directions of the Dream Start programs were discussed.

  • The study investigates the type of organizational culture, using the organizational culture assessment instrument(OCAI) developed by Cameron and Quinn based on the competing value model(CVM), and analyzed the gap between current and desirable organizational culture empirically. The analytic results show that while the organizational members prefer the relational organizational culture as a dominant organizational culture on the current level. Also they prefer the relational organizational culture as a desirable organizational culture on the future level. In addition, the diagnosis of organizational culture by the type of status reveals that while the public educational personnel and staff recognized the relational organizational culture as a strong culture, the local public service employee identified the hierarchical culture as a dominant culture on the current level. Those findings suggest the following implications. First, the sustainable management of organizational culture requires the suitable strategic tools. That is to say, they need to introduce and carry out practical strategies to sustain change and control for each type of organizational culture. Second, despite the fact that the balance among four types of organizational culture is needed the strategy to reinforce the dominant culture, considering the types of status and affiliation.

  • The application of BIM that can manage and integrate information generated during the entire life cycle of buildings in domestic and overseas construction projects is becoming active. When BIM is utilized in the construction phase, it can shorten the construction period, reduce the occurrence of reworks and improve collaboration capability. However, there are limitations in applying BIM to the construction phase due to the insufficient definition level of domestic BIM guidelines and inadequate design standards. In this regard, this study developed BIM model requirements checklist for the application of BIM in the construction phase. To develop the checklists, 21 domestic and overseas BIM guidelines, three public construction projects and four private construction projects to which construction BIM was applied, were analyzed. Based on the guidelines and cases, a total of 62 construction BIM model requirements (31 model objects and 31 attribute rules) and proposed construction BIM model requirement checklists by dividing the 61 requirements according to the requirement and purpose for utilization were identified. It is expected that the practical applications of the checklists proposed in this study will improve the level of BIM model in construction phase. In addition, this study has its significance as a basic research that can be used in the development of standardized guidelines for BIM model in construction phase from academic aspects.
