The Korean system of labor adjudication on the cases of unfair dismissal and unfair labor practices has been criticized by labor and management in spite of the strong point that the Labor Relations Commission processes the cases quickly. This paper empirically investigates the effectiveness of labor adjudication dealt by the Labor Relations Commission with economic approach. It shows that the grievences of labor and management on the existing labor adjudication system have come from the inadequate processes of labor adjudication rather than the favorable or unfavorable ruling. It also shows that a major deterrent to make an effective labor adjudication system has been not the problems of the selfish attitude and expectation of labor and management but the improper attitude and quality of the member and staff of the Labor Relations Commission.

The Seoul subway system has one of the highest transport shares in the city of Seoul. A high number of passengers means that a high level of crimes of all kinds occur on the city's subway system. As such, Seoul Metro, created the Subway Protective Guards System in 2009, in an effort to enhance safety on the subway. But this innovative new system did not resolve problems. In fact, many citizens came to question the effectiveness of the new system, as it did not yield tangible results. This study seeks to deduce the problems and activation strategy of the Subway Protective Guards System. An in-depth study was conducted by interviewing subway protective guards who were squad leaders with five or more years of relevant work experience. Semi-structured interview analysis was utilized to evaluate their responses. Specifically, their responses were deduced to identify the strengths and weaknesses internal to the system and the opportunities and threats posed by the environment external to the system. This study presents measures to improve the system based on the aforementioned analysis. Measures for improvement focused on the following areas: the adoption of an education system in response to terror; recruitment and the possibility of becoming a permanent employee; obtaining partial judicial powers; improvement of work environment; and intensifying the promotion of the system.

The field of cadastre and land administration is susceptible to changes in technological development and requires a robust system to respond. In Mongolia, there is a need for a future-oriented and robust cadastral system to cope with these changes. Therefore, this study chose the Land Administration Domain Model (LADM) which is created by the International Organization for Standardization(ISO), and analyzed for its application to the cadastral system of Mongolia. For the application of LADM for Mongolia, we analyzed four packages and each class of LADM based on characteristics of Mongolia's cadastral system and cases of countries applying LADM. As a result of this analysis, we have completed LADM national profiling in Mongolia and proposed the possibility of applying LADM. In the future, based on this research, application of LADM will play an important role in Mongolian cadastral system where the current data model standardization is not established and is useful as a reference model.

Recently there has been a trend of hiring more foreign labors in the Korean construction sites after the introduction of the government policy for foreign workers since 2007, called Employment Permit System(EPS). With the trend in the sites, the skilled and unskilled foreign workers would have become a main resource in the construction site workforce. This study aims to analyzing the effectiveness and the reality of working status for the foreign workforce. In doing so, both mail questionnaire survey and face to face interview with site managers and foreign labors in 38 apartment construction sites around Seoul region have been performed. The results of survey has been compared to the former research, which has been done for foreign labors hired under the old government policy, called Industrial Trainee System. This study found that there still exist many problems in reality of utilizing foreign workers in the sites, and proposed various recommendations for the effective use of foreign labors in the Korean construction industry.

In the 4th Industrial Revolution, information is collected and analyzed from people and objects through the rapid development of ICT. It is possible to create value. However, there are many legal and institutional restrictions on the collection of information aimed at people.Therefore, in-depth research on the protection and use of personal information in the rapidly changing cyber security environment is needed. The purpose of this study is to protect and utilize personal information for the operation of AI (Artificial Intelligence) and big data during the 4th Industrial Revolution. It is to seek a paradigm shift. The organization of the research for this is: Chapter 1 examines the meaning of personal information during the 4th Industrial Revolution, Chapter 2 presents the framework for the review and analysis of prior research. In Chapter 3, after analyzing policies for the protection and utilization of personal information in major countries, Chapter 4 looks at the paradigm shift in personal information protection during the 4th Industrial Revolution and how to respond. Chapter 5 made some policy suggestions for the protection and utilization of personal information.

The study, by reviewing and analysing the system of occupational education and training, aims to provide some substantial informations for the activation of occupational education and training in the construction sector. The result shows that the current system doesn't substantially reflect the realities of employment structure in the sector, and thus, fails to respond to skilled-worker development. It is also observed that most of the occupational education and training institutions have difficulties in recruiting trainees due to daily construction workers' negative attitudes toward the current system. Therefore, it is necessary i) to improve occupational education and training system, ii) to tackle in-depth analysis of daily construction workers' reasons for the negative perceptions, and iii) to develop the responding alternatives.

"Law on price announcement for real estate" which was revised as of Jan. 19, 2016 (will be enforced as of Sep. 1, 2016) decided the introduction of 'Price announcement system for non-residential property' for the first time. However, its introduction seems to be delayed based on two reasons. Firstly the methodology for introduction of non-property system is not definitized, despite many problems were brought up for current tax base of non-residential property. In addition, changes in tax base will place a burden on the government. In this regard, this study analyzed actual transaction price data throughout one year to analyze equity of taxation for non-residential property and to find major factor which affects on the tax base, in relation with the change of current public announcement system to actual transaction based system. And this is the first study that applied actual transaction price to non-residential property.

Firm's competitive advantage and profitability can be gained over competitors by human resources and human resource management that are characterized by idiosyncrasies or differentiation. Yet, the results of previous studies have been a emerging consensus that the isomorphism and homogeneity of HRM and HR practices among firms regardless of thoese industrial areas, size, organizational settings, etc. are universal. Based on the previous studies of similarities of HRM, the paper theoretically investigates the background and reasons of introducing similar HR practices among firms. The paper shows the dynamism of HR system in Korean firms, adapting a new HR system. Three types of reasons are found, coercive isomorphism, mimetic isomorphism, and normative isomorphism. However, it is also discussed that there is an important gap in the theoretical and empirical research. More empirical research is suggested in order for gaining meaningful results on HR studies.

In this paper, we estimate the effects of the two most important means of summer time demand side management in Korean power market: adjustment of vacation or repair timing and the voluntary saving program. We use regression analyses to estimate how effective these two programs are in reducing the peak time demand during the summer. Our results show that adjustment of vacation or repair timing actually reduces the daily peak demand by 0.53 kWh per one kWh reported reduction calculated from the agreements between Kepco and the users. The voluntary saving program reduces the daily peak by 0.57 kWh per one kWh reported reduction calculated from the agreements between Kepco and the users. However, when we include these two effects in the same regression model, their respective estimated effects become much weaker.

The conditions for separation and identification of anionic and nonionic surfactants by thin layer chromatography were investigated. Polyoxy alkylene-type nonionic surfactants were identified by the distribution of alkyl chain and alkylene oxide. Various polyoxyethylenated nonyl phenols were easily distinguished by densitometer. Some anionic surfactants were identified by $R_f$ and color, and the mixtures of anionic and nonionic surfactants were separated. Polyoxyethylenated fatty acid was separated into three parts of diester, monoester and polyethylene glycol, respectively, and the mixed ratio was determined by densitomer. All the experiments were carried out in 13-20 minutes, and the length of run was 80mm.
