Although various policies have been conducted on safety work of construction equipment such as lifts, tower cranes, and mobile cranes, institutional and managerial problems, and improvement measures, accidents are still not decreasing. This study tried to identify differences in the viewpoints of supervisors, safety managers, and construction machinery operators and to obtain survey data on the awareness and necessity of related safety education. In conclusion, accidents would be reduced when workers received effective training on accurate work methods, safety rules, and recognition and removal of risk factors.

ROK Navy Landing Ship Fast(LSF-II) is equipped with special equipment that is not compatible with other combat ships due to special missions. So there are almost no maintenance capabilities except for simple repair parts replacement and maintenance parts. The researcher determined that the way to solve these problems was to apply Performance Based Logistics (PBL), and reviewed the cases of PBL applications abroad and domestically. To confirm the current maintenance capability, we visited LSF-II operation unit to identify maintenance capabilities for each mounted equipment, and interviews with operators and maintenance practitioners confirmed the limitations of outsourcing maintenance and the need to apply PBL. In order to analyze the effect of PBL application, the measure of effectiveness and measure of performance were selected based on the opinions of LSF-II operation/maintenance practitioners and PBL experts and the practical experience of this researcher. A survey was conducted on operation/maintenance practitioners and professional personnel. Based on the survey results, the effect of applying PBL was analyzed using the AHP technique, and an efficient PBL application plan was proposed for LSF-II.

In the Fourth Industrial Revolution, students are required to develop in areas such as communication, logic, and creative thinking. Therefore, the university libraries need to develop new services so that students can grow up to be suitable for the new social situations. Havruta is an educational approach that can meet these needs and is one of the measures the university libraries want to apply. Thus, through 1) the investigation of the concept of Havruta, 2) the case study of domestic and foreign university libraries, and 3) interview of the Havtura-based service, this study 4) proposed the Havruta service applicable to the university libraries and 5) conducted a survey of operators and users on the awareness of the Havruta service, space, and contents of the Havruta service, and the willingness of the Havruta service. Results of the survey analysis revealed implications for the areas of the Havruta service - Havruta theme, group organization, textbook rental, simplication of space reservation, data sharing and motivation system.

In Korea, there are many attempts to automate architectural design tasks, focusing on government-led national R&D projects and private operators, in order to enhance global competitiveness and productivity of the building service industry. However, according to a survey of architectural design office practitioners, only 25% (9 out of 37) have used it, suggesting that there are fewer cases of practical use in the field compared to research and investment in automation technology development, and there are discrepancies between automation and technology development items required in the field. In this study, the priority of automation of planning and design work of architectural design office practitioners is derived, and a comparative analysis is conducted with domestic architectural design automation service items based on the priority. A survey was conducted on practitioners of domestic architectural design offices to derive automation priorities for 19 items of architectural planning and design work. Based on the derived priorities, the degree of reflection of the working-level automation needs of domestic services was confirmed by comparing them with the domestic architectural planning and design automation service items. As a result, it was confirmed that domestic architectural planning and design automation services did not properly reflect the priority of planning and design work automation of architectural design office practitioners. This suggests that it is necessary to reflect the priorities derived in this study in technology development in order to increase the cases of practical use of the automation technology in the working environment and improve the productivity of service.

The region trunk line railroad route considering regional characters is the final aim of railroad management to operators and passengers. For reflecting these aspect to make policies, The study has been performed by defining and analyzing the informations. According to the methodological and political research, First of all, The feature for demand and supply of railroad in the region trunk line railroad route is that demand aspect was excessively influenced by supply aspect. The demand sensitivity was measured very high on the supply changes. The survey, Containing the regional characters, result the railway and bus use patterns are clearly different and this feature is simiral to that of janghang and pohang district. also, In railroad case, Demand shifts from railroad to other transport sensitively. Therefore, We make some new index besides existing index, which like to management index, rate of boarding, rate of using. After that, We suggest passengers and operator's win-win alternatives.

The mobile telecommunication sector is increasingly gathering way becoming a key area for the economic development in Uzbekistan. One way to promote competition among providers is the introduction of a number portability service. This paper estimates subscriber's willingness to pay (WTP) for the MNP service in the mobile communication market in Uzbekistan. Consumer valuation was estimated using a conjoint analysis. Since number portability had not been introduced at the time of the study, stated preference data from the conjoint survey was used. Results indicate that currently subscribers do not attach a lot of importance to the MNP service, while price and service quality are most valuable components. The results of this study provide important implication for mobile network operators and policy developers on potential MNP implementation.
