  • The recycled aggregates which were produced from the waste concretes have the disadvantages of inferior properties for natural aggregate. Therefore, in order to reuse the recycled aggregate it must be solved to improve the quality of recycled aggregate. In this study, the quality of recycled aggregate was improved by the surface treatment method using the colloidal silica solution. And, in order to examine the possibility of reusing the surface coated recycled aggregate in constructing concrete structures, we studied the mechanical properties and durability of the concrete using the surface coated recycled aggregates and the other concrete.

  • In the post-corona era, telemedicine is becoming more important. This is the case in which it is written, in terms of this study, and in relation to the relationship between the Koreans and the Korean government. In addition, the aim is to prepare effective measures and seek policy suggestions for expanding the introduction of domestic telemedicine in the future. Although Japan has insisted on the necessity of introducing telemedicine in the medical community, it has institutionalized it with a cautious attitude until the establishment of telemedicine. On the other hand, South Korea lacks clear provisions on medical fees for telemedicine and legal measures regarding the responsibility for medical malpractice. Therefore, a clear legal interpretation of the telemedicine subject is needed, and a strategic approach is prioritized, including guidelines and measures for the legal responsibilities and limitations of physicians and patients.

  • The Academic library services are based on specialized subject resources in academic fields in order to maximize the desirable direction of its services. Accordingly, there are some academic libraries introduced and applied subject specialist librarians. However, they can not objectively analyze the strengths and weaknesses as well as future directions to subject specialized service. The purpose of this study examined three library cases which the structure of organized subject specialist librarian. It tried to give a set of effective guidelines for academic libraries to introduce subject specialist librarian. Analysis showed that the initial problems of subject specialist librarians in its early stages are appeared: carrying out the role, appraisal-results in human resource decision making such as rewards and promotion. In order to successful introduction of subject specialist librarian in academic library, there are solutions that solving the problems which happen in early stage, active guidance and public relations strategy for faculty, approaching to activate integration within its library and cooperating among academic libraries should be back up for improving effectiveness in the long term.

  • Recent rapid changes such as construction market reduction, lowest bidding system of construction cost, five days per week system, and post-construction sale system are inevitably accelerating the competitiveness between construction companies. Those rapid changes of construction environment require construction companies, which are main participants of construction industry, to adapt to the changes and more to lead new construction environment. However, there are many construction uncertainties which could delay construction completion. Without the proper identification of construction uncertainties, structured strategy establishment and management of construction schedule, the competitive advantages of construction duration could not be made. Thus this paper limited the research boundary to construction duration competitiveness instead of general strategy establishment. Recognizing the importance of proper calculation of construction duration, requirements of construction duration reduction and limited researches related to construction schedule strategy, we established the 25 strategies for construction duration competitivenss by internal and external construction environment analysis and SWOT analysis, and then elicited the first considerations to accomplish the strategies through concensus of all the staffs by questionnaire, brainstroming and face-to-face interviews.

  • The most important thing for the national GIS development is considered to be the standardization, especially the development of the standard coding scheme for the GIS features and attributes. The comparative study on those of the several international transfer standard is, therefore, very meaningful. In this paper we analyzed the features and attributes coding catalogue for the three different exchange standards; SDTS, DIGEST and SP-57. And also the new coding scheme is proposed as the unified standard frame to be used for all the GIS related application and the digital product.

  • In this study, I examine mutual shock spillover effects among interest rate differences, won-dollar foreign exchange change rates, and stock market returns in Korea during the daily sample period from the beginning of 1995 to the October 16, 2015, using the multivariate GARCH (generalized autoregressive conditional heteroscedasticity) BEKK (Baba-Engle-Kraft-Kroner) model framework. Major findings are as follows. Throughout the 6 model estimation results of variance equations determining return spillovers covered from symmetric and asymmetric models of total sample period and two crisis sub-sample periods composed of Korean FX Crisis Times and Global Financial Crisis Times, shock spillovers are shown to exist mainly from stock market return shocks. Stock market shocks including down-shocks from the asymmetric models are shown to transfer to those other two markets most successfully. Therefore it is most important to maintain stable financial markets that a policy design for stock market stabilization such as mitigating stock market volatility.

  • Methodist church materials are classified with three types, centered on the organizations manufacturing and holding materials such as 1) 'materials of the Methodist headquarter' governing all of the Methodist churches in Korea, 2) 'materials of theological seminary libraries' holding academic study books related to theology, and 3) 'materials manufactured in individual churches'. In this manner, the Methodist church materials imply homogeneity in theme, but the materials have identity from each other, because organizations are different each other, too. By a characteristic of each organizations, to use Methodist church document done a director of each organization is demanded collaboration between the material departments of each organizations, this study intends to analysis material department operation status of three Methodist church organizations. As a result of analysis, it is necessary to perform the prior tasks, such as reconstructing organization to accomplish an original function of the Methodist headquarter, developing operation regulation classified with the Methodist church group, and constructing material management system.

  • The inefficient operation of Busan New Port is due to container-terminal operators being dispersed in small groups, rather than being integrated. This dispersion increased following the reorganization of global shipping alliances in 2016 and causes unnecessary Inter-terminal Transportation(ITT) and ship delays. Studies of integrated operations for larger container terminals show that integration is not going well, however, due to the pre-emptive task that follows the integrated operation. Therefore, in this study, we divided the integrated operation into stages based on a simulated model of the container terminals in Busan New Port. The simulation took into account future increases in the ship's enlargement and terminal congestion, and the operational effects of each type of integrated operation were analyzed and evaluated.

  • This study conducted qualitative research using Geochang Wolseong Space Creative Science Museum as a case study to investigate the organizational and operational status of small local science museums during the COVID-19 pandemic, as a basic study for the dissemination of scientific culture and public understanding of science. To analyze the situation of the science museum, an evaluation framework was developed, and information obtained through various communication channels and in-depth interviews with information commissioners of the museum were used for the study. As of 2020, when COVID-19 was at its peak, this science museum showed a clear decline in sales and visitor numbers compared to the previous year. Despite this situation, the museum was found to be using crisis management methods such as introducing unface-to-face programs, managing exhibits, and using various promotional media. However, the shortage of professional personnel, excessive workload of employees, and absence of differentiation from other science museums remain as challenges to be addressed in the future for sustainable earth science.
