The objective of this study is to analyze the effect of the quality of the Internal Accounting Control System(IACS) on Executive compensation, and to determine whether this relationship depends on the effectiveness of corporate governance. For the analysis, 6,343 firm-year data listed on the Korea Exchange from 2011 to 2016 were used. The results are as follows. First, Executive compensation was decreased in companies with low quality of IACS to provide a penalty for management. Second, the negative relationship between the weaknesses of IACS and Executive compensation was found to be strengthened when the corporate governance was effectively operated. These findings suggest that information about the quality of the IACS can be usefully used to reasonably identify the executive compensation policy, and that corporate governance needs to be operated more efficiently.

The purpose of this study is to interpret how the long-term care evaluation system implements in the actual service settings with institutional isomorphism and decoupling based on new-institutional theory. This study conducted in-depth interview with employees engaged in 7 long term care service facilities. Directed qualitative content analysis was used to analyze the data. As a result, unlike the intention of the long-term care evaluation system to improve the efficiency of the organization by market competition, it found that organizations forcibly adapted a evaluation system to rely on government's resources and it results in isomorphism phenomena which is similar between organizations. This results confirmed that the evaluation system has implemented in the direction of enhancing the government's role to standardize and institutionalize the long-term care service rather than improving the efficiency of the organization by market competition. This study also partially found the phenomenon of decoupling between organizational formal structure accompanied by isomorphism and real behaviors. These results suggest that it is required to improve government's evaluation indicators on the issue of inefficiency caused by dual structure of organizations. In addition, this study proposes that government's evaluation index which is reflected the characteristics of care service is necessary for operating.

Due to structural problems in the transportation market, such as fraudulent competition and multi-level transportation transactions, tariff are not properly refIected to the final trucker even if freight tariff are increased due to diesel price hikes and transportation cost increases. By Launched "standard tariff system" in 2017 based on the trucks, government would tried to guarantee the minimum tariff such that prevents overloading, speeding, and strain for trucker. However, It is necessary to analyze in advance the issue of the system and its impact on container freight. Thus, this study analyzes the issues and countermeasures related to the tariff system that is formed when the "Truck Safety Rates" is introduced, and also analyzes the influence factors of the expenditure cost on the container freight which is applied to the "Truck Safety Rates".

According to Law on Allocation and Trading of GHG Allowances of 2013 in Korea as well as the 2014 National Master Plan for Korean Emissions Trading System, the System should be designed to minimize the change in the market positions of the affected firms. In this paper, we investigate how that principle might become ineffective by the ways of distributing allowances and applying different accounting methods using a Cournot duopoly model. Although the way of allocating allowances freely to firms combined with accounting them for having no values would minimize their market positions, it would not the most cost-effective way of GHG reduction since it does not provide financial market with accurate informations.

Efficient snow-removing work is one of important processes of winter road management. Calcium chloride has been used as a typical deicing agent in Korea. It presents superial performance as snow deicing agents, however it has been known to give serious environmental problem and to deteriorate durability of concrete structure in road by corrosion. The environment-friendly road deicing agents made from the waste material which is liquid phase organic matter that is Ca Mg and reactant of organic acid (nitric acid and propionic acid) have been introduced by number of researchers. They indicated the calcium magnesium salt of organic acids have advantage over the calcium choride in terms of lower production unit cost by resources recycling and can solve environmental problem and durability deterioration of structures. In this study, the deicing performance of calcium magnesium salt of organic acids(CMO) is investigated based on the series of experiments including the test for heat of dissolution, freezing point, ice melting test and ice penetration test.

This study investigates the association between financial reporting strategy and the directors' and officers' liability insurance. Since D&O insurance protects officers and directors against the risks of shareholder litigation, it is possible that, because of moral hazard, managers will be more willing to participate in opportunistic financial reporting such as earnings manipulation when they are covered by a generous D&O insurance policy. This paper examines the association between D&O insurance and financial reporting, specifically whether the purchase of D&O insurance affects earnings manipulation. On the other side, the firms engage earnings management are willing to purchase D&O insurance, this study tests whether earnings manipulation affects D&O purchases using listed firms in Korean stock market from 2006 to 2008. This paper finds that firms with higher discretionary accruals are less likely to purchase D&O insurance implies that managers who are participating in earnings manipulation are not willing to purchase D&O insurance. The relation between discretionary accruals and D&O is significantly negative which indicate D&O insurance purchase does not trigger earnings manipulation rather it alleviates opportunistic reporting behavior.

Managers are required to adopt and implement the human resource management practice that fit firm's strategy the most, so that optimize overall performance. However, the time and relative resources that any firm has are limited, which demands managers to understand the relative importance of all sorts of HR practice and promote them in an order of their relative importance. This study follows the universal perspective and contingency perspective(according to firm size and strategy type), try to identify the most effective HR practice on performance as well as their relative importance by "CART Ensemble" analysis. The results are as follows. From universal perspective, firms always need to high level of integration between strategy and HR department, decision making participation, autonomy of speed of working, and autonomy of way of working. Contingency perspective also suggested the importance of integration between HRM and strategy. But others are different case by case. This study suggests useful implications for managers.

Importance of Information Systems in banking industry is higher than that of other industries. This study, based on a case study of a bank, analyzes the current status of information systems (IS) audit and proposes future directions in the area of IS control and audit. Major problems identified in the study include deficiency of IS and audit process, and inability of audit function to improve IS process. In addition, deficiency of staffing level and investment in R&D, and lack of competency and independence of audit staff are identified. In order to solve the problems, the following directions were proposed proper division of functions among audit related departments, utilization of outside audit function, and adoption of CSA, CAAT, career path program, risk-based audit approach. The results of the studs will provide valuable implications to banks and companies in other industries. Also the research framework employed in the study can be utilized in the future research in IS control and audit.

Problem solving ability can be fostered by dealing with many different types of problems. We investigated how $5^{th}$ and $6^{th}$ graders who did not learn traditional algebraic methods might approach the word problems of simultaneous equations. This result reveals that the strategy of guess-and-check serves as a basis for elementary school students in solving simultaneous equations. A noticeable remark is that students used the guess-and-check strategy in various ways. Whereas some students changed a variable given in the problem step by step, others did in a sophisticated way focusing on the relation between two variables. Moreover, some students were able to write an equation which was not typical but meaningful and correct. This paper emphasizes the need of connections between pre-algebraic and algebraic solutions.

This paper examines the effect of price ceiling regulation on the new apartment price. The analysis procedure of the study is divided into two parts, which stand for a case study on the effect of price control on the new apartment price and the survey of real estate experts on price ceiling regulation. The empirical results of our case study show that the selling price under price ceiling regulation is generally lower than that in the situation of price deregulation, in terms of the land development expense and construction cost. With regard to the survey results, more than half of respondents have opinions that price ceiling regulation has an impact on the new apartment price and lowers the price. They are equally divided pro and con regarding the problem of keeping or discarding the regulation.
