Recently electronic journal articles prevail throughout researchers because of the development of internet and electronic publishing technology. It is caused by limited collection development budget, lack of physical storage space for printed journals in libraries, and the user convenience of web services. But from the view of ownership, electronic journals can be unfavorable to information users or libraries who cannot have the permanent right to access all the subscribed journals. Actually the libraries only have right to access journals for subscription periods in using electronic journals. So the users and libraries are willing to purchase printed journals in spite of high cost. As an basis for collaborative collection development and sharing preservation of Korean libraries for the foreign journals, the data analysis is carried out for the journals collection in terms of regional distribution, overlapping status, and journal subject. And the considerables are discussed for collaborative strategic collection development, which means the reduction of overlapped subscription and maximization of utilization in a national standpoint.

Mobile Ad hoc Network (MANET) is a collection of nodes or communication devices that wish to communicate without any fixed infrastructure and predetermined organization of available links. The effort has been made by proposing a scheme to overcome the critical security issue in MANET. The insufficiency of security considerations in the design of Ad hoc On-Demand Distance Vector protocol makes it vulnerable to the threats of collaborative black hole attacks, where hacker nodes attack the data packets and drop them instead of forwarding. To secure mobile ad hoc networks from collaborative black hole attacks, we implement our scheme and considered sensor's energy as a key feature with a better packet delivery ratio, less delay time and high throughput. The proposed scheme has offered an improved solution to diminish collaborative black hole attacks with high performance and benchmark results as compared to the existing schemes EDRIAODV and DRIAODV respectively. This paper has shown that throughput and packet delivery ratio increase while the end to end delay decreases as compared to existing schemes. It also reduces the overall energy consumption and network traffic by maintaining accuracy and high detection rate which is more safe and reliable for future work.

The 3rd Library Development Plan raises the need to secure space through the establishment of a regional repository library as the issue of holding books is highlighted as a common problem in public libraries. The Korean Library Law Act also impose the responsibility of integrated management of local library materials on the regional representative library. Accordingly, this study aimed at Busan Metropolitan Library, which is operating a collaborative repository in earnest among regional representative libraries, and investigated the operation status of the collaborative repository and the perception of public librarians about the collaborative repository. The data necessary for the study were obtained through surveys, interviews, field surveys, and internal data analysis. Through this, the purpose of this study was to provide basic data that will help the Busan Metropolitan Library to operate the collaborative repository efficiently in the future, and at the same time, to present basic data that can be used as a reference for the operation of the collaborative repository of the representative libraries of other regions.

Academic research libraries are seeking a long-term preservation plan for journals for cost-effective stewardship. The emergence of shared print archives has given the library community the opportunity to resolve the problem of the lack of library storage and build a collaborative long-term archiving plan for the print journals. The purpose of this study is to examine Western Regional Storage Trust(WEST), the largest print journal archiving program in North America, and identify their strategies for building a distributed, retrospective print repository service for journals. Based on the analysis, this article will discuss the development of new trends of collaborative library management in a digital age.

We conducted a survey in collaboration with the Chungcheongbuk-do Office of Education to assess the current status of collections in public libraries affiliated with the Office of Education. The objective of this survey was to identify the current challenges and determine when these libraries are expected to reach a state of collection saturation. Libraries under the jurisdiction of the Chungcheongbuk-do Office of Education are currently facing significant challenges due to severe collection saturation. This underscores the pressing need for the systematic expansion and operation of a collaborative preservation library for a swift response. In the future, it appears that the focus during the transfer process will primarily be on transferring collection-oriented materials. Given the difficulty in providing preservation facilities at individual library levels, materials with preservation value, such as rare books and specialized resources, will need to be transferred to the collaborative preservation library. Additionally, the development of policies and regulations related to material preservation seems necessary. Furthermore, when transferring materials to the collaborative preservation library in the future, it appears that criteria for material transfer will be needed, particularly concerning issues such as a decrease in usage rates for less frequently accessed materials. Subsequent research should consider conducting a survey on the collection saturation status of public libraries under local governments in order to assess the overall need for collection expansion in all public libraries within Chungcheongbuk-do.

Small and medium sized enterprises' (SMEs) environmental performance and activities have been often of great concern toward sustainability as they have been playing a critically important role in the economic and industrial development. Among many initiatives to engage SMEs into the sustainability framework, Supply Chain Environmental Management (SCEM) of large companies has a great potential to persuade SMEs to adopt environmentally improved activities. This study investigated the relationship between SCEM approaches of large companies and environmental activities of SMEs in the Korean electronics industry. A postal questionnaire survey was used as a data collection method, and factor analysis and regression analysis were applied to analyse the collected data. The empirical findings suggested that SCEM approaches of large companies have positive impacts on environmental activities of SMEs. Among SCEM approaches, the collaborative approach was more effective than the arm's-length approach. Additionally, this study found positive impacts of trans-national SCEM approaches on SMEs' environmental activities.

In order to respond to changes in college's educational goals and talents, university libraries need to be transformed into spaces that support creative and collaborative learning. Apart from overseas cases, it is necessary to discuss the development of creative and collaborative learning spaces appropriate to the situation of Korean university libraries. This purpose of this study is to provide an effective guide to university libraries planning to develop creative and cooperative learning spaces. To this end, this study conducted a literature review to define the concept of a creative and collaborative learning space in a university library, collected and analyzed cases of creative and collaborative learning space of Korean university libraries, and proposed a model for developing creative and collaborative learning space for university library. Case collection was carried out through field visits to 12 university libraries. In addition, in-depth interviews were conducted with the staffs in charge of the construction and operation of five university libraries selected in consideration of the operating entity, region, and scale. This study is meaningful in that it intensively researched and analyzed the advanced cases of creative and collaborative learning spaces in Korea to derive suggestions that can be used in the field of domestic university libraries.

The current study explored a pedagogical possibility of utilizing magic as a source of communicative tasks for young learners in developing their English speaking proficiency. Fifteen primary school students participated in the study, which consisted of a 17-week period of task-based English instruction and data collection. The participants were instructed to accomplish various types of magic task through collaborative group interaction. The data collected for the study pertained to the students' linguistic outputs, interactions in group and attitudes to English learning. They were analyzed for how magic tasks affect the students' English proficiency developments and group interactions. The study results suggested the significant improvement in the students' English speaking proficiencies. They revealed that magic tasks contributed to a) enhancing the motivation to speak in English, b) stimulating the creative and problem-solving processes, and c) providing the sufficient opportunity to repeat and internalize the target expressions. The study results also indicated that the students' satisfaction with their group members and tasks seemed to have positive influences on their interactions in group and English proficiency development. Further discussion and pedagogical implications are provided as well as the study limitations.

The Fishtail Chimney system mounted on 1 channel smoking machine is not appropriate for the routine analysis of sidestream smoke, because of its low repeatability and very long time required for smoke collection. To overcome this inconvenience, we developed a new sidestream smoke collecting apparatus compatible for 8 channel linear smoking machine. An electric motor driven stroke and automatic control system were adopted in this device to maximize convenience and efficiency of its operation. Also, we carried out the international collaborative study on monitoring sidestream smoke analysis to test the performance of this system. From the statistical analysis of the data obtained in our laboratory and other participating labs, it has been indicated that the newly developed sidestream smoke collection apparatus could be applicable to the routine analysis of sidestream smoke.
