국가 온실가스 감축수단의 확보를 위해 전략적으로 감축기술을 선택하는 것은 매우 중요한 문제이다. 특히, 공공의 기술선택은 다양한 요인들을 고려하는 포괄적인 접근의 필요성이 강조된다. 그러나 지금까지의 논의들은 기술적, 경제적 요인에 중심을 두고 기술선택을 다루고 있으며, 일관된 선택 기준이 적용되지 않고 있다. 본 연구는 국가 온실가스 감축기술을 선택하기 위한 지표를 개발하고자 전문가 22인을 대상으로 델파이 기법을 사용하였다. 이를 통해 타당성이 확보된 국가 온실가스 감축기술 선택 지표를 개발하였으며, 기술, 경제, 환경, 정책, 사회의 관점을 종합적으로 반영하는 것에 대한 적절성을 확인하였다. 상용화기술은 5개 항목의 16개 지표, 신기술은 5개 항목의 18개 지표로 구성되었다. 본 연구를 통해 제시된 기술선택 지표는 국가 온실가스 감축기술 선택을 위한 의사결정 도구로 활용될 수 있을 것이며, 국가 온실가스 감축기술의 적용과 확보에 관한 판단기준 연구에 토대를 제공할 것으로 기대한다.

Clients demands have been changed by construction circumstances such as high-technology, megaprojects, and the complexity of construction. Advanced foreign nations have already introduced and applied new project delivery systems (i.e, CM, DB, etc.) to deal with the change of such that. Korea has also promoted variation of the delivery systems for the progressive measure to the rapid changeable situation. Even though government has made his efforts as stated above, some clients have uniformly used those to public construction projects. That is because there are not selection criteria of project delivery system for clients. Therefore, this study presented the selection criteria of project delivery system based on project types in the public large construction projects. In addition, the study has verified the viability of the presented models through consultation with professionals and experts.

This study is a demand research for the selection of public safety science and technology equipment and suggests an empirical research method. The technology demand survey is the beginning of the selection of innovative technology. And it is the basis of collecting information required for the technology required in the market and helping to apply it to the field. The demand survey for police science and technology can reduce the uncertainty of crime prevention and help the smooth implementation of security policies. However, in Korea, adoption of security science and technology equipment was centered on social issues or researchers' opinions rather than the demands of field users. Until, there was no research has been conducted on the demands of field police officers for selection of security science and technology equipment in Korea. Also, there was no preferential study for the demand for security science and technology equipment. Therefore, this study proposes a methodology that can systematically identify the needs for the technology and equipment of field experts suitable for the public security situation for the selection of security science and technology equipment. Specifically, we propose a sample design for a technology classification system and a survey tool for technology awareness and satisfaction. It is expected that this tool will provide a classification system for security science and technology equipment selected for the Korean police and will help determine the priority of equipment suitable for the field.

Recently, the interoperability has become more important to enhance the net-centric capabilities of the warfighter. DITA (Defense Information Technical stAndard) is the set of IT standards for improving interoperability, scalability, effectiveness, and efficiency. In this paper, we analyzed the standardizing process to derive the selection criteria and structurized the derived selection criteria using the KJ (Kawakita Jiro) method. Finally, we developed an evaluation model for selecting a standard for DITA using AHP (Analytic Hierarchy Process). As a result, we present eight selection criteria (maintainability, trend, stability, portability, effect of other standard, constraint of the network, and applicability to the systems). We also applied some examples that several IT standards to our selection model for validating the model. We expect our model to help to decide objectively whether the new standard can be listed in DITA.

본 연구에서는 농촌지역의 거주하는 노인들을 대상으로 공공의료기관과 민간의료기관에 대한 신뢰가 의료기관 선택에 미치는 영향을 분석하였고 이에 연관성을 파악함으로서 의료기관 신뢰도를 높여 농촌지역에 거주하는 노인들의 공공의료기관 이용율을 높이기 위한 방법을 도출하기 위하여 시행되었다. 이를 위해 S읍외 4곳에 30년이상 거주하며, 병원이용율이 높은 만65세 이상 노인을 대상으로 공공의료기관과 민간의료기관을 사전 설명후 의료서비스 신뢰도 설문조사를 실시하였다. 분석결과는 첫째, 농촌에 거주하는 노인들은 민간 의료기관이용을 더 선호하였고. 둘째, 공공 의료기관과 민간의료기관의 신뢰도와 의료기관 선택 간에 연관성이 있었다. 본 연구 결과를 종합해보면, 조사 대상자들의 공공 및 민간의료기관에 대한 신뢰도가 의료기관의 선택에 영향을 미친다고 나타났다. 따라서 본 연구의 결과 향후 공공의료기관은 의료서비스의 신뢰도를 제고할 필요성이 제기되며, 민간의료기관과 같이 공공의료기관도 자체적인 경영개선 노력이 필요할 것으로 사료된다.

창조경제를 내세운 박근혜 정부는 인력채용에 있어서도 학벌, 스펙 위주의 인재선발을 지양한다. 따라서 공공기관이나 기업이 창조경제를 뒷받침할 만한 인재선발을 추진하고 있다. 이를 위해 도입한 방식이 국가직무능력표준 이다. 특히 IT분야는 전 공공기관에서 인재가 필요하다. 따라서 본 논문은 국가직무능력표준의 IT인재 부문을 연구하고, 국가직무능력표준을 적용한 IT인재 선발에 대해 분석한다. 본 논문은 국가 공공기관 뿐만 아니라 창조 경제를 발휘하는 기업에서 필요한 IT인재상에 대한 중요한 연구 자료가 될 것이다.

A variety of approaches are being applied to improve the existing ex-ante evaluation by expert panels in publicly funded R&D. While the objective evaluation criteria are constantly being improved to screen and select the superior projects, alternative approaches such as random prioritization and logical modeling are also underway to overcome the conservative bias of reviewers and to secure disruptive innovation. This study intends to find critical implications for ex-ante evaluation of public R&D system from the comparison of Indonesia and Korea. For the comparative analysis, literature review and expert in-depth interviews are conducted on the national R&D system and the selection evaluation process. In Korea, the selection criteria of projects are legally promulgated for establishing an objective evaluation system, and at the program level, the major considerations in the planning process are specified by Presidential Decree. On the other hand, while Indonesia conducts R&D in 47 strategic fields largely by public research institutes (PRI) based on the non-competitive government contributions. This study draws out implications of institutionalizing the planning process at the level of program, and of increasing the ratio of contract-based competitive funding at the level of project in the national R&D portfolio.

Identifying highly discriminating genes is a critical step in tumor recognition tasks based on microarray gene expression profile data and machine learning. Gene selection based on tree models has been the subject of several studies. However, these methods are based on a single-tree model, often not robust to ultra-highdimensional microarray datasets, resulting in the loss of useful information and unsatisfactory classification accuracy. Motivated by the limitations of single-tree-based gene selection, in this study, ensemble gene selection methods based on multiple-tree models were studied to improve the classification performance of tumor identification. Specifically, we selected the three most representative tree models: ID3, random forest, and gradient boosting decision tree. Each tree model selects top-n genes from the microarray dataset based on its intrinsic mechanism. Subsequently, three ensemble gene selection methods were investigated, namely multipletree model intersection, multiple-tree module union, and multiple-tree module cross-union, were investigated. Experimental results on five benchmark public microarray gene expression datasets proved that the multiple tree module union is significantly superior to gene selection based on a single tree model and other competitive gene selection methods in classification accuracy.

With the radical changes and advancements of industrial economy, it is required to secure product competitiveness through technological innovations to overcome uncertain environments and generate a driving force for sustainable growth. So the Korea government introduced the superior product selection system in 1996 and has granted such incentives as priority purchasing and contracts the products of SME whose technological capabilities have passed the screening criteria. After analyzing the ambiguity of the evaluation procurement used in designation of excellent product, this study proposed seven detailed indexes for evaluation.
