Recently, the number of companies consigning their personal information management work has been increasing; they consign the work for various reasons and purposes, for example, in order to reduce costs related to personal information managers, improve efficiency through professional performance and to improve service quality. As such, since the cases where an consigning agency - not the personal information manager - handles personal information are increasing due to the increase of consigning of the personal information management work, we need to concerned with and pay attention to how much such agency makes efforts for personal information protection. In this regard, this study suggests a plan for efficient management of the agency during the course of consigning work as well as a list of requirements for personal information protection to be considered in each phase of the following; establishment of personal information protection framework for all consigning work processes, selection of consigning agency, execution of consigning contract, operation and management of consigning work, and termination of contract.

To establish an appropriate policy for robotic surgery in Korea, the National Evidence-based Collaborating Agency (NECA) and the Korean Society of Health Policy and Administration held a round-table conference (RTC) to gather opinions through a comprehensive discussion of scientific information in gastric cancer. The NECA RTC is a public discussion forum wherein experts from diverse fields and members of the lay public conduct in-depth discussions on a selected social issue in the health and medical field. For this study, representatives from the medical field, patient groups, industry, the press, and policy makers participated in a discussion focused on the medical and scientific evidence for the use of robotic surgery in gastric cancer. According to the RTC results, robotic surgery showed more favorable results in safety and efficacy than open surgery and it is similar to laparoscopy. When the cost-effectiveness of robotic surgery and laparoscopy is compared, robotic surgery costs are higher but there was no difference between the two of them in terms of effectiveness (pain, quality of life, complications, etc.). In order to resolve the high cost issue of the robotic surgery, a proper policy should be implemented to facilitate the development of a cost-effective model of the robotic surgery equipment. The higher cost of robotic surgery require more evidence of its safety and efficacy as well as the cost-effectiveness issues of this method. Discussions on the national insurance coverage of robotic surgery seems to be necessary in the near future.

We have developed a cost-effective and facile method to manufacture a pouch-type chemical vapor sampler. Originally, the sampler was developed by U. S. Army Natick Soldier Research, Development, and Engineering Center(NSRDEC) to determine the protective capability of individual protective ensembles or Man-in-Simulant Test (MIST). They used a selectively permeable high density polyethylene(HDPE) as front membrane and aluminum/ Nylon barrier film as an impermeable back sheet in order to mimic the actual adsorption process that occurs when the skin is exposed to chemical weapons. However, it costs over twenty dollars per sampler and the minimum of quantity is 2500 per order. In addition, it is inconvenient to employ a variety of adsorbents into the sampler, which could prevent MIST researchers to do various tests for development of MIST methodologies. Here, we report the simple method to manufacture the sampler in a laboratory scale. All the materials we used are easily obtainable and inexpensive. In addition, all the procedures we perform are generally known. We used methyl salicylate(MeS) vapor to be adsorbed into the sampler and employed several different adsorbents to evaluate the performance of samplers. The results obtained by home-made samplers and commercially avaliable one showed no significant differences. Also, MeS vapor was selectively adsorbed into the sampler depending on adsorbents. We conclude that home-made samplers are capable of collecting any kind of chemical vapor for a variety of purposes.

This study deals with construction contract bid-rigging by Japanese contractors who monopolized the construction market of the Korean Peninsula during the Japanese colonial rule, and investigates the abuses of the contract bid-rigging. First of all, construction contract bid-rigging in Korea was triggered by Japanese construction contractors and contract brokers, who had savored the benefits of bidrigging in Japan and had repeated the bid-rigging in Korea since 1903. Second, the agency played a significant role to mediate construction contractors, and existed throughout the Japanese colonial rule on the Korean Peninsula with changing their names. Most of them were engaged in major contract bid-rigging scandals. Among them was Construction Association of Korea, which existed for over 13 years. The agencies had took part in governmental services since the mid-1930s when Japan exploited Korean people during wartime, and focused on sweating human resources for the constructions. Third, one of the biggest construction bid-rigging scandals during the Japanese colonial rule was "the 1st and 2nd scandal on Daegu construction contract bid-rigging." Indeed, the second scandal paved the way for the serial scandals: "Kyeongseong construction contract bid-rigging scandal", "Busan construction contract bid-rigging scandal", and other cases throughout the nation. Fourth, along with the contract bid-rigging cases related to the Japanese Government-General of Korea and local authorities, bid-riggings firmly took rooted in local governments' farmland reclamation projects in the 1920s and the poor relief services in the 1930s. The "bid-rigging charges" forced contractors to compensate their losses with exploiting material costs and labor costs, generating serious problems. The construction contract bid-rigging enabled Japan to monopolize the construction industry and to sweat farmers on the Korean Peninsula. Against this backdrop, contract bid-rigging by Japanese construction contractors during the its colonization made Korean contractors ruled out, and helped Japanese monopolize the industry. A large amount of bid-rigging charges drove Japanese contractors to do fraudulent work with cheap materials and to exploit Korean labor force.

Of safety check regulation, 'Construction Technology Promotion Act' and 'Special Act on the Safety Control of Public Structures' contain provisions about the content of safety in construction works and the items of safety checks in the maintenance aspect and thus contribute to accident prevention in the construction industry. Of the regulations responsible for the practical safety of workers, the safety check regulation of Ministry of Employment and Labor demand for safety check from the start of construction based on an agreement with a concerned agency to the completion of construction solely based on 'Guidance Standards for the Specialized Disaster Prevention Instruction in Article 32 of Occupational Safety and Health Act' and 'Appropriation and Usage Standards of Safety and Health Management Costs in the Construction Industry'. There is, however, a huge gap, as well, in them according to client agencies. In small construction sites ordered by a private organization, checks are done formally with no detailed regulations. As a result, the costs of checks continue to drop with only the contract kept intact. This study examined the forms of safety checks practically done in the Jeju region, distinguished and compared them by the construction costs, calculated proper costs based on each construction act, and further proposed improvement measures for the detailed regulations.

This study aims to determine how ownership structure (share-holding ratio of insiders, foreigners) affects agent costs (the portion of asset efficiency or non-operating expenses) through empirical analysis. However, as existing studies on correlations between ownership structure and agent costs adopted Pooled OLS Model, this study focused on additionally formulating Fixed Effect Model and Random Effect Model aimed to reflect the time of data formation and corporate effects as study models based on verification results on the suitability of Pooled-OLS Model before comparative analysis for the purpose of improvement of credibility and statistical validity of the results of empirical analysis based on the premise that the Pooled OLS Model is not reliable enough to verify massive panel data. The data has been accumulated over 10 years from 1998 to 2007 after the IMF crisis hit the nation, from a subject 331 companies except for financial institutions. As a result of the empirical analysis, verification of the suitability of model has determined that the Random Effect Model is appropriate in terms of asset efficiency among agent costs items. On the other hand, the Fixed Effect Model is appropriate in terms of non-operating costs. As a result of the empirical analysis according to the appropriate model, no hypothesis adopted in the Pooled OLS Model has been accepted. This suggests that developing an appropriate model is more important than other factors for the purpose of generating statistically significant empirical results by showing that different empirical results are produced according to the type of empirical analysis.

In this paper, we first introduce a systematic verification procedure for hierarchically structured avionics system. By making use of equipment models, it can perform individual verifications of each subsystem, integrated verifications of multiple subsystems, and an integrated verification of a whole system. A multi-mode system integration laboratory is then proposed to make it possible to execute various individual or integrated verification tests at the same time. By mathematically proving that the proposed multi-mode system integration laboratory needs less verification time than the conventional verification methodology, it is expected to enhance the efficiency of the systematic verification procedure and as a result, reduce the overall verification period and costs.

Purpose - If control-ownership disparity is large, managers will not actively reduce costs; rather, they will maintain unutilized resources or possess surplus resources even when sales decrease with the purpose of increasing personal utility from status, power, compensation, and prestige. These managers' utility maximizing tendencies cause cost stickiness. We examine whether asymmetric behavior related to costs becomes stronger when there is a large disparity between ownership and control rights. Research design, data, and methodology - We construct a regression model to examine the relationship between control-ownership disparity and cost stickiness. STICKY, a dependent variable representing cost stickiness is a value found using the method of Weiss (2010), and Disparity is an interest variable that shows control-ownership disparity. Results - This study is based from the unique situations in Korea, in which high control-ownership disparity is common in firms. Large control-ownership disparity was found to increase cost stickiness of corporations. Conclusions - The results of this study imply that controlling shareholders may be regarded as a threat to the interests of minority shareholders and corporate values especially when controlling shareholders have significant influence over managers or the power to make managerial decisions as owners of a corporation.

In many countries, a Single Window system for simplifications is establishing in order to reduce works submitted double data and compliance costs. A Single Window is defined as a facility that allows parties involved in trade and transport to lodge standardized information and documents with a single entry point to fulfil all import, export, and transit-related regulatory requirements. A Single window can bring improved level of security, faster clearance and reduced compliance costs. UN/CEFACT released "Recommendation and Guidelines on establishing a Single Window to enhance the efficient exchange of information between trade and government". Also, WCO has made progress several projects to assist effective establishing a single window, i.e. CDM, UCR, ICT. Korea has being established a single window system, "e-trade platform" connected with trade, clearance, logistics, marketing and payment system. Some suggestions to establish a effective single window system in Korea are as follows. Firstly, it is necessary to clearly define roles and responsibilities of a lead agency in a single window system and form a organic relationship with PGA. Secondly, a single window system has to be progressed by stages, namely, customs clearance portal system should be established first, and later established e-trade platform. Lastly, the Korean government has to take part in CDM project to gain an advantage over other countries.

Social solidarity, equity in financing, and efficiency in administration have been core issues in the development of Korean health insurance reformation since 1988. This study is to investigate the trend of administrative cost in Korean National Health Insurance from various aspects. For the analysis of administrative cost, the expenditures of each insurance society and the National Health Insurance Corporation are divided into 4 items of (1) insurance benefit, (2) administrative cost, (3) an agency provision accounts, (4) other expenses, and then they are reorganized. The analyses based on 5 types of the health insurance administrative cost showed that efficiency in administration has been improved generally. We, however, should consider qualitative aspects such as customer's satisfaction with health insurance administration, prompt service, control of unjust expenditure (unjust claims), and provision of medical service including health consultation in assessing efficiency of administration. And, in order to connect the administrative costs of health insurance with efficiency, we need to give a fundamentally new definition, which can contain elaborateness of expenditure in details including the structure and evaluation method of administrative costs. It may be necessary to develop new indicators or analyzing methods hereafter.
