  • In many cases, operation of regional trunk lines is not profitable to railway operators. Nevertheless, railway operators are under pressure to manage regional trunk lines running under deficits, to better serve public interests. Given this situation, railway operators need to optimize assets by adjusting train schedules or changing the number of trains running. When railway operators judge the operation of a regional trunk line, the B/C ratio is generally used as a management index. This ratio is not considered part of strategic operational policy over the long term, and excessively influenced by the aspects of supply and demand over the short term. Accordingly, this study focused on indices that might be used to prevent worsening deficits and provide long term strategic operation policies, main indices to better measure economic situations, and auxiliary indices to supplement the main index. The main indices were measured in conventional ways to target experts and employees. This study presents quantitative standards, which are intended to be used to create itemized criteria through an Analytic Hierarchy Process, for better decision-making.

  • BIM can be utilized variously in construction management(CM) in the respect that it helps to manage comprehensively the construction information and make reliable decisions, but the adoption of BIM is insufficient in the CM area. The purpose of this study is to develop work process models and their guides in order to utilize BIM effectively in CM work at construction stage. This study defined BIM functions as 'BIM converting design', 'Model review', 'Data extraction', 'Automatic estimate', '4D simulation', 'Drawing creation', 'Engineering sector linkage analysis' through literature search, and generated CM works applicable to BIM by analyzing the CM work and process. This study developed BIM-based CM work process models by reconstructing the existing work process in connection with BIM function through an analysis on the relationship between BIM function and CM work, and reconstructing the role of each project participants. In order to improve the usefulness of the developed models, guides that described the BIM works of project participants were prepared through interviews and case studies. To validate the utilization of the models, a comparative analysis on the BIM process of precedent studies was also made and a survey was conducted on experts. This study can contribute to increasing the utilization of BIM in the CM area and can be helpful for CM companies to develop an in-house BIM guide. In the future, it will be necessary to make an assessment on the models from a business perspective through case applications and constantly update BIM-based CM work process model in consideration of the expansion of CM work due to the application of BIM.

  • $I$ $am$ $a$ $Weasel$ > is a radically different communicative form in several ways. It innovatively utilizes podcast, a kind of internet radio format while dealing actively with thorny political issues and scandals in much direct and challenging fashion. Also this program adopts politically-charged parody, sharp critique of current socio-political issues, as well as lively dialogues through which the program provides both acute political awareness and entertainment. As a new kind of talk show and an alternative media form, this program has gained much popularity and attention since its appearance. Considering the fact that the journalistic fields and public spheres are in disarray through the government intervention and wrought with fierce partisanship and political polarization, the role of this program needs to be examined both cautiously and contextually. This study aims to shed some lights on the multifaceted and much contentious role of $I$ $am$ $a$ $Weasel$ > through a textual reading and discourse analysis, as well as email interviews.

  • This paper investigates accounting principles about social infrastructure on Korean National Accounting Standard and on National Accounting Standards from other countries that adopted a accruals- based national accounting standards. Social infrastructure as assets has important value in financial statements of Korea and deterioration or insufficient management of social infrastructure accompanies a huge social cost. Therefore, understanding the characteristics and related accounting standard for social infrastructure is necessary. To do this, we examine the accounting standards of U.S., New Zealand, and Australia. We also review the financial statement of local government. Based on these findings, this paper suggests that a preventive-asset management approach should be applied and alternative depreciation method for social infrastructures is developed. Moreover, a local government needs to provide important accounting information to the public in a timely and reliably manner.

  • Current socioeconomic condition in South Korea is characterized by growing country with highly unemployment rate. Enhancing service industry, therefore, is one of the important government policy issues. In addition to quantitative growth of service industries, OECD comparisons between countries as shown in the competitiveness of the domestic service industry, followed by a very low-level, enhancing the competitiveness of service industries are also important issues of national policy. In particular, finance, education, insurance industry, such as relatively large enterprises have entered the service industry to remain competitive and comparable, but the case of small service industries, has shown a very low level of competitiveness. Thus, the world's leading technology and IT infrastructure can be applied to small and medium-sized service industry in order to improve productivity, customer satisfaction, and service infrastructure, resulting in improving competitiveness. The purpose of this study is to develop government supporting policy issues by analyzing the current usage of IT, problems and requirement analysis, and critical success factors for applying IT to small and medium-sized service industries. For a survey 2,000 samples are collected from service companies. The results show that IT usage is very important to improve competitiveness in small and medium sized service industry. In addition, customized it solutions are needed to satisfy different characteristics of service industry depends on types of business. Finally, government supporting programs of IT has to be improved. The results would be able to provide directions and guide lines of IT utilization in service industries.

  • Automobile engine oil is the most important lubricant for operating as the engine is started. Recently, manufacturers of the automotive industry and lubricants are considerably improving the quality of oil with additive to extend change cycle period. Most customers are recommended genuine oil among different types from shop expert. Through this report we suggest another reference point for consumer to pick highly efficient lubricant. This report is investigated oil compounds to compare with 6 different automotive considering actual running condition for 7 months. we conducted experiment from physical and chemical perspectives. In the field, through various experiments oil compounds between mineral oil and synthetic oil are largely distinguished in oxidation, viscosity, fluid and TBN. These are influenced by engine part wear as piston, bearing etc. Comparing various investigation with different oil the performance of synthetic oil is shown better condition in flash point, oxidation stability and also found less in change pollutant iron, Al compounds. Additives of oil show clear difference Ca level in detergent-dispersant both mineral oil and synthetic oil. And Zn in extreme pressure additives and P in Lubricity improver make no difference to both.

  • The current status of Korean social work can be summarized as multiple complexities and ambiguities not only in ideological but in practical aspects. Although they have long been considered as an unique feature of social work as one of representative human service professions, the extent of such complexities are now reaching the culmination enough to raise the questions about the very nature of social work practice. This study aims to analyse such ambiguities and complexities around the field of social work in a systematic ways with the theory of liquid modernization, an creative framework for modern society, coined by Zygmunt Bauman who is now considered as one of the leading sociologist and thinker. The study shows clearly that social work in Korea is nowadays entering the phase of liquid modern society and specific features of liquidity of modern society such as consumerism, privatization, corruption of publicity etc are founded in the areas of social work. To make it worse, social work are thinking about the anachronical response to this flow of liquidity by selecting the strategies useful in solid modern era, not in the liquid one. In this context, the study suggests that social work practice have to prepare to adequate measures to secure its own autonomy and sustain genuine identification from the ruthless melting power of liquid modern society.

  • The rapid growth of information technologies and data networks has increased the volume of data generated from scholarly research and the possibilities of re-using and sharing such data. However, there is a serious problem of management and sharing of research data due to the lack of facilitating policies and supporting infrastructure. In particular, few data repositories exist that support systematic collection and sharing of research data in the humanities. In this regard, the Korea Research Memory (KRM) established by the Korea Research Foundation is a rare exception. The purpose of this research is to present specific processes and strategies that can facilitate the data collection, reuse and preservation through the KRM using task analysis and source document gathering as main focal points. In addition, in order for the effective collection and sharing of research data, the following recommendations are proposed: 1) the need for the adoption of data management plan related policies that govern the collection and sharing of research data generated from publicly funded research projects, 2) the need for training and support services for individual researchers and research institutes, 3) the need for training data specialists, and 4) the citation scheme and structure designed for research data.

  • The advent of the full-fledged Internet of Things era will bring together various types of information through Internet of Things devices, and the vast amount of information collected will be generated as new information by the analysis process. To effectively store this generated information, a flexible and scalable cloud computing system is advantageous. Therefore, the main determinants for effective client system acceptance are viewed as motivator factor (economics, efficiency, etc.) and hindrance factor (transitional costs, security issues, etc.) and the purpose of this study is to determine which detailed factors play a major role in making new system acceptance decisions around harm. The factors required to determine the major priorities are defined as the system acceptance determinants from the technical point of view obtained through the literature review, and the questionnaire is prepared based on the factors derived, and the survey is conducted on the experts concerned. In addition, the AHP analysis aims to achieve a final priority by performing a bifurcation between components for measuring a decision unit. Furthermore, the results of this study will serve as an important basis for making decisions based on acceptance (enabling) of technology.
