The concern and request of high-quality software has been increased according to the rapid transition of society to information-oriented era. Therefore activities of software quality management are regarded as serious as the activities of software development. Moreover, stakeholder of software may have various views of software quality. And some quality characteristics need to be managed with priorities in Software Development Life Cycle (SDLC). Hence we recognized that weights of quality characteristics might be useful to improve efficiency of quality management activities. However, this topic has not actively issued because its necessity and effectiveness has been ignored. This paper presents a technique to decide weights of software quality characteristics in SDLC. It is based on ISO/IEC 9126 which is the standard for software product quality. It is accomplished by questionnaires intended for stakeholder in software development and weight analysis through AHP (Analytic Hierarchical Process) method. Accordingly, it can select quality characteristics by weight in SDLC. And then it helps us to acquire high duality software through measuring software quality quantitatively and expecting the quality after completion of software development.

This study aims to analyze the importances of various SCM adoption factors suggested in precedent researches with AHP. SCM adoption factors were categorized by four types: organization factor, transaction factor, relation factor, and information factor. Each factor has sub-factors. Organization factor has five sub-factors: adoption strategy, support of CEO, maturity of information technology, development of assessment system, and innovation leadership. Transaction factor has three sub-factors: transaction period, delivery/quality, and shared goal. Relation factor has five sub-factors: trust, collaboration, inter-dependence, conflict, and immersion. Information factor has three sub-factors: information quality, information share, and information exchange. There are sixteen sub-factors altogether. Analyzing the importances of SCM adoption factors with AHP, the importance of organization factor(.387) ranked the highest. Relation factor(.291), information factor(.167), and transaction factor(.155) followed. Putting the analysis results of primary hierarchy factors and secondary hierarchy factors together, support of CEO(.169) ranked the highest and trust(.124), adoption strateg (.089), share goal(.081), information exchange(.069), collaboration(.064), and information share (.057) followed.

말모둠은 특성에 따라서 여러 성격을 나타내게 된다. 하지만 말모둠의 특성을 자동적으로 알아내는 방법은 간단하지 않다. 중요 단어를 가지고 있으면 말모둠에서 통계적으로 많은 부분에서 적용시켜 말모둠의 특성을 파악할 수 있다. 본 논문에서는 한국어 말모둠에서 나타나는 동사류 단어들의 빈도를 분석한다. 또한, 사람이 직접 중요도를 평가한 사전의 단어들과 말모둠에 나타나는 단어들을 비교해서 통계적 차이점을 알아보고, 그 차이점을 통해 앞으로 연구할 일에 대해서 토론한다. 간단한 실험을 통해 사람의 평가한 중요도 점수의 효용성도 알아본다.

Public conflict in domestic project has been increased and it results in direct and indirect damages. In order to reduce the loss, there have been diverse researches on the public conflict. However, most of researches tend to mainly focus on characteristics of the conflict. Considering the conflict occurred in SOC project, a research of conflict with project characteristics is necessary. In response to consider the relationships between characteristics of project and conflict, this paper aims to present the relative importance of the relationships. We conducted literature reviews and interviews with experts to select main characteristics of projects and public conflicts. Based on the selected four main characteristics each, we analyzed the relationships between them using Fuzzy AHP. The results show that SOC construction project type among project characteristics exerts the most important effect on overall public conflict. Especially conflict factors and conflict phases among public characteristics are critically influenced by project types. The findings provide a foundation for a conflict management reflecting varying public conflicts due to project characteristics.

The purpose of this study is to analyze the importance and performance of CK-1, The research subjects were self-enrolled questionnaires for students who took social economics subjects and analyzed the importance and performance using IPA. As a result of the research, it is necessary to establish the basis of social economic specialization in order to achieve the goal of CK-1, and it is necessary to establish educational curriculum related to industry and academy in addition to cultivating creative talents. And to improve the importance of these programs and improve their performance in order to enhance the undergraduate education and attract the creative economy. The implications of this study are as follows: The results of the evaluation to achieve the goals of CK-1 recognize that the importance and the performance of the social economy students are high. However, It is necessary to make efforts to improve the university constitution, to improve the education of the undergraduate education, and to attract the creative economy in order to characterize the local university targeted by the Ministry of Education and the project team.

We analyze the risk factors identified for ex-ante evaluation regarding government R&D programs. In particular, we empirically examined to what extent each risk factor is perceived to be important by the stage of R&D, technology field, researcher's career and experience. The empirical results show that technology risk is perceive to be less important for basic research, while market risk more perceived to be important in the IT field. Political risk is perceived to be less important for the university faculty, while researchers with government R&D project experience gave more value to legal risk factor.

ISO/IEC 14598-4(소프트웨어 제품의 구매자 평가 지침)는 소프트웨어 평가에서 무결성 수준의 중요성을 전제로 품질특성의 우선순위를 제시하고 있다. 그러나 이러한 제시는 현실에 적용한 것이 없는 이론적인 것이다. 본 연구에서는 ISO/IEC 14598-4에서 제시한 무결성 수준에 따른 품질특성의 중요도가 타당성이 있는지를 실증하였다. 중요도 산출을 위해 15명을 면담 조사하였으며, 이는 중요도 계산을 위한 AHP를 활용하기에 충분한 표본의 개수이다. 본 연구결과와 ISO/IEC 14598-4에서 제시한 품질특성의 중요도 순위는 일부가 상이하게 나타났다. 또한 척도를 이용한 소프트웨어 품질경영을 시작할 때 통상적으로 권고되는 척도의 수 범위(최소 4개~최대 8개) 내에서 무결성 수준에 관계없이 동일한 척도가 선정되었다.

When considering the introduction of a new technology, it is important to accurately grasp and selectively apply the technical characteristics related to the technology in order to fully utilize the advantages of the technology. In this study, the technical characteristics of high relative importance were analyzed in order to increase the efficiency of new application of blockchain technology by companies. The technical characteristics of the blockchain identified through previous research were reclassified from the perspective of the system hierarchy, and sub-factors of the technical characteristics were derived. In addition, a questionnaire survey on the relative importance of technical characteristics was conducted for internal experts and SI experts using the Analytical Hierarchy Process (AHP) technique. As a result of the analysis, respondents evaluated data protection as the most important factor in the threat of hacking related to security. In addition, it was different that the comparison results of the importance of the technical characteristics between the experts in the company and the SI experts and the priority of the technical characteristics between the expert groups by industry. It is expected that the results of this study will be usefully utilized when using blockchain technology in enterprises in line with the upcoming changes of the 4th industrial revolution. An empirical analysis of the internal and external factors required for adoption of blockchain technology by industry and the effect of technology introduction will be a meaningful study.

제품의 정성적 품질평가에서, 제품의 최종품질을 구성하는 다수의 특성에 대한 만족도가 언어로써 표현되어 소비자의 구매행동이란 의사결정으로 표출되는데, 이러한 주관적 평가에는 평가의 애매함(fuzziness)이 수반되므로 품질의 평가구조를 합리적으로 파악하기 위해서는 애매함의 존재를 고려에 넣지 않으면 안된다. 다수의 품질특성이 계층적(hierarchical)인 구조로 연결되어 최상위 품질특성으로 구성되며, 특성간의 중요도(relative importances)가 계층별로 결정되는 경우, 이들 개개의 특성에 대한 만족도의 평가로부터 어떤 구조적인 관계를 통해 그 제품에 대한 종합평가가 이루어지나, 개개의 특성에 대한 평가가 애매한 이상 최종 결과인 종합적 만족도도 애매한 것으로 된다. 즉, 평가모델의 구조도 평가의 패턴도 퍼지화되므로 이러한 평가에서 퍼지이론의 응용에 따른 효과를 가장 크게 기대할 수 있는 퍼지추론모델을 이용하여 계층간, 품질특성간의 퍼지관계와 특성의 중요도 및 언어변수(linguistic variables)의 형태로 주어지는 입력정보로써 품질구조를 명확히 하고, 패턴인식(pattern recognition)의 개념을 이용하여 평가자의 제품에 대한 평가결과를 언어로써 표현한다.
