The purpose of this study is to generate a proper regulation improvement direction of the public IT project contract law through the current four contract methods and three methods of the awarding party of a contract method. The research method for this paper is derived from the written materials of the present public IT project contract law. Two problems have been processed in order to produce the results: the current contract methods and the awarding party of a contract method. The current contract methods consist of a competition contract, a private contract, and a supply methodology contract. The methods of the awarding party of a contract display a qualified evaluation regulation, the 2nd step competition bid, a standard cost separation tender, and a contract by a negotiation. The results exhibit that the general competition contract consists of four improvement items. The contract by a negotiation contains five improvement items. The group private contract has one improvement item. And the private contract includes one improvement item. These results implicate that the current public IT project contract law demands better improvement work for the ubiquitous Korea.

Plants protect against viruses through passive and active resistance mechanisms, and in most cases characterized thus far, natural recessive resistance to potyviruses has been mapped to mutations in the eukaryotic initiation factor eIF4E or eIF(iso)4E genes. Five eIF4E copies and three eIF(iso)4E copies were detected in Brassica rapa. The eIF4E and eIF(iso)4E genes could interact with turnip mosaic virus (TuMV) viral protein linked to the genome (VPg) to initiate virus translation. From the yeast two-hybrid system (Y2H) and bimolecular fluorescence complementation (BiFC) assays, the TuMV-CHN2/CHN3 VPgs could not interact with BraA.eIF4E.a/c or BraA.eIF(iso)4E.c, but they could interact with BraA.eIF(iso)4E.a in B. rapa. Further analysis indicated that the amino acid substitution L186F (nt T556C) in TuMV-UK1 VPg was important for the interaction networks between the TuMV VPg and eIF(iso)4E proteins. An interaction model of the BraA. eIF(iso)4E protein with TuMV VPg was constructed to infer the effect of the significant amino acids on the interaction of TuMV VPgs-eIF(iso)4Es, particularly whether the L186F in TuMV-UK1 VPg could change the structure of the TuMV-UK1 VPg protein, which may terminate the interaction of the BraA.eIF(iso)4E and TuMV VPg protein. This study provides new insights into the interactions between plant viruses and translation initiation factors to reveal the working of key amino acids.

In this paper, a reliable and convenient evaluation method for the adequacy of any radial distribution line's voltage drop is proposed for improvement of the voltage regulation of the distribution line under operation. Using the voltage measurement of the first load branch point and the last point on the given distribution line its average line voltage drop and the line voltage drop variance by pure load variation are computed. And by these values and allowable or required line drop from proper voltage regulation view point, present adequency index and operation improvement index of the line drop are newly introduced for the evaluation of the given distribution line's voltage regulation. As a result of application to the 4 cases of study, the proposed method is proved to be reliable and convenient.

In this study, the current regulation of the water source energy, one of the renewable energy, was analyzed, and the improvement plan for the high efficient data center cooling system was suggested. In the improvement plan, the design and construction guidelines of the water source energy system permit to adopt the cooling and heating system with or without heat pump. In addition, it should also include the system operated in the cooling mode only all year-round. The domestic test standards to consider the water source operating conditions should be developed. Especially, it is highly recommended that the test standards to include the system with forced cooling and free cooling modes related with the enhanced data center cooling system adopting the water source energy.

Key concepts in South Korean nuclear safety regulation are safety and risk. Nuclear regulation in South Korea has required reactor designs and safeguards that reduce the risk of a major accident to less than one in a million reactor-years-a risk supposedly low enough to be acceptable. To date, in South Korean nuclear safety regulation has involved the establishment of many technical standards to enable administration enforcement. In scientific lawsuits in which the legal issue is the validity of specialized technical standards that are used for judge whether a particular nuclear power plant is to be licensed, the concept of uncertainty law is often raised with regard to what extent the examination and judgment by the judicial power affects a discretion made by the administrative office. In other words, the safety standards for nuclear power plants has been adapted as a form of the scientific technical standards widely under the idea of uncertainty law. Thus, the improvement of nuclear safety regulation in South Korea seems to depend on the rational lawmaking and a reasonable, judicial examination of the scientific standards on nuclear safety.

The purpose of this study was to develop an intervention program for the improvement of the emotion regulation of 5-year-olds and to analyze the effects of this program on their emotion regulation and social behavior. The participants consisted of 56 5-year-olds from two day care center located in a metropolitan area of Korea. The experimental group (n=28) participated in the intervention program, and the comparative group (n=28) did not. This intervention program was developed to deal with peer relationships, and consists of activities designed to cover all domains of the Korean National Early Education Standard. The emotion regulation and social behavior were measured before and after the experiment. The data were analyzed making use of ANCOVA. Our results indicate that this program had the effect of improving the emotion regulation and social behavior on the part of 5-year-olds.

Nowadays there are lots of changes in the domestic railroad industries because of the reorganization in the industries, operation of KTX and expansion of city train in local areas. To cope with these changes effectively, domestic & abroad safety guideline and regulation were investigated and reviewed by railroad safety technical development project. Based on this project, domestic rolling stock safety regulation was established in the July and December on 2005. It's been a 3 years after 2005 and to confirm whether there are some problems to applicate the regulation in the field like korail, the necessity of reviewing the regulation gains force. In this study, to improve the field application in rolling stock safety regulation, we investigated the results of integrated railroad audit system and internal safety regulation system in a train operator and also collected the opinions from train manufacturer. Then through the result of investigation and collection of the opinions, we proposed the amendment to the rolling stock safety regulation.

This paper analyzes the impact of the change in telecommunication regulation changes including the unification of telecommunication service on network investment. The unification of telecommunication service plays a role of separating behavior regulation from entrance regulation and reducing entrance constraints. Therefore, it is expected that the market spillover effect is high through the improvement of behavior regulation. In addition, the effects of the other regulation changes in the 2010 Telecommunications Business Act revision are analyzed. This paper discusses critical factors affecting the decision making process in respect to the firm level and analyzes the impact path guiding investment and innovation. The key findings are as follows. First, the impact of entrance deregulation depends on the intensity of deregulation. If the intensity is not high, this regulation increases the incentive on investment and innovation. However, if the intensity is high as shown in abolishing of licensing, it affects the incentive negatively. Second, if interconnection regulation focuses on existing facilities or the intensity is not strong, this light handed regulation might increase investment and innovation. However, if interconnection obligation is expanded to the facility not constructed or the facility applying new technology, this regulation might deteriorate investment. Third, price deregulation increases the competition of service but it also increases the business opportunity, which means positive effect on investment. Finally, the paper proposes the guideline for telecommunications policy.
