The purpose of this study is to empirically analyze whether performance-oriented remuneration systems in public thermal power generation companies substantially induces organizational commitment of employees, and contributes to organizational performance. According to the study, adequacy of salary and individual work evaluation have significant effects on organizational commitment, whereas external and internal evaluations for pay-for-performance remuneration systems do not have a significant effect. Annual salary for performance and pay-for-performance systems have a significant influence on organizational performance. In addition, because annual salary and individual work evaluation of the performance-oriented remuneration system have significant effects on both the indirect effect, through organizational commitment, as well as the direct effect on organizational performance, there exists a partially mediated effect on organizational commitment. Conversely, because external and internal evaluations do not significantly affect organizational commitment, there is no means of verifying the mediating effect. Studies suggest that a fair annual salary system for performance employed in conjunction with a pay-for-performance system will provide positive impacts on organizational performance and employee loyalty.

This paper aims to scrutinize the possibility of mereology as philosophically satisfiable metalogic. Motivation for this is straightforward. As I see, a traditional approach to metalogic presented in the name of mathematical logic posits the existence of mathematical entities such as sets, functions, models, etc. to give definitions of logical concepts like logical consequence. As a result, whenever logic is used in any individual sciences, this set-theoretical metalogic cannot but add these mathematical entities to the domain of them. This fact makes this approach contradict to the ontological conservativeness of logic. Mereology, however, has been alleged to be ontologically innocent, while it is a formal system very similar to set theory. So it may well be that some people thought of mereology as a good substitute for set theoretic metalanguage and concepts for ontologically neutral metalogic. Unfortunately, when we look into argument for the ontological innocence of mereology, we can find that mereological entities such as mereological sums or fusions are not ontologically neutral. Thus we can conclude that mereological approach to metalogic is not promising at all.

More than sixty percentage of highway in South Korea were constructed by concrete pavements and more than half of the concrete pavements were twenty years or older. The most of highway have difficulty in providing detour due to the traffic and road condition of South Korea. So far, asphalt concrete has been used for the overlay of aged cement concrete pavement. However, the frequent early damage and maintenance of typical asphalt overlay due to repetitive maintenance causes inconvenience of road users and expensive costs. It is necessary to investigate the factors affecting the performance of asphalt concrete overlay to improve the performance of asphalt overlay. However, the performance data of asphalt concrete overlay in South Korea does not exist. In this research, to investigate on the factors affecting the life of asphalt concrete overlay was attempted based on statistical analysis of the performance data of asphalt concrete overlay included in LTPP (Long-Term Pavement Performance) Database of U.S.A.

Analyses of the three-storied stone pagoda at the Bulguksa temple in Gyeongju were carried out in order to identify the cause for material characteristics of inorganic contaminants and conservation treatment materials. Results indicated that foreign soil or weathering soil caused yellow discoloration of the pagoda, reddish-brown contaminants were formed by goethite (FeOOH), an iron oxide mineral, and black pollutants were formed by manganese (Mn) oxide, leading to discoloration of the rock. Among the restoration materials used in the past, cement mortar could cause whitening by reacting with the external environment. The results were used as basic standards to evaluate the material characteristics of the surface contaminants and identify a set of effective conservation treatments. Nevertheless, continuous monitoring is required, as there is a high possibility of regeneration of pollutants in the future because of the continuous exposure of the pagoda to the external environment.

There are almost 18,000 dams including about 1,200 large dams in Korea. The large dams are well operated and maintained by KWATER(Korea Water Resource Corporation), KRC(Korea Rural Community & Agriculture Corporation) and KHNP(Korea Hydro & Nuclear Power Co., Ltd.). Several research reports concern with the safety of these large dams are presented but there is no paper concerned with small dams which has diversion tunnel through the dam body. The purpose of this study is to show the common defects of small dams according to various cases of degradation of dams and the repair and retrofit methods which applied to the damaged dams. And this study performed resistivity survey to evaluate the effect of retrofitting dam. Also, this study tries to present the solution which concerned with these common defects in maintenance and design steps.

Recently, the rapid proliferation, introduction, and application of the fourth industrial revolution technology has emerged as a trend in the construction market. Building Information Model (BIM) technology is a multidimensional information system that forms the basis of the fourth industrial revolution technology. The river sector utilizing this information-based system is also being actively reviewed, for example, the current measures for maintenance. In recent years, active research and current work should be done to reflect the need for river experts to introduce BIM into the river field. In addition, the development of tools and support software for establishing various information systems is essential for the activation of facility maintenance information systems reflecting advanced technology and to establish and operate management plans. A study on the maintenance of river facilities involves using existing drawings to build a three-dimensional (3D) information model, check the damage utilizing it, and inform it, and utilize it as the data for maintenance reinforcement. This study involved determining a method to build a river facility without the existing information system and using the property maintenance information with 3D modeling to provide a more effective and highly utilized management plan to check maintenance operations and manage damages.

This research analyzed the status and problems of civilian expert programs for landscape architects to suggest alternatives to improve the current system. Literature research focused on the issues of the legal definition of civilian experts, the background of the program, and related regulations. Based on the understanding of the legal system, the research analyzed the operation status, structure, roles of the civilian expert program of local governments where landscape architects were delegated as civilian experts. Currently, 50 local governments are running the civilian expert program, and landscape architects are working as civilian experts in 11 institutions. The majority of landscape architects are working as MA or general architects. Only SMG runs an independent general landscape architect program. Based on the literature research and interviews with 16 experts, the research examined four main issues related to the program. First, the legal system issues of the civilian expert programs are related to the regulations assuming architects as experts. Revising the current legal system is a better alternative than promulgating a new law for landscape architects. Second, the compensation issue was a main problem related to operation. Securing a sufficient budget and more effective administration is required to solve the problem. Third, related to the role, the tasks being limited to consultation were regarded as the main problem. Although landscape architects wanted more opportunities to directly participate in the project's design, the fairness of the public project contracting system needed to be considered. Fourth, the competence issue is related to the number of available landscape architects. This issue can be solved by expanding the pool of civilian experts to adjacent disciplines, such as public design or landscape management.
