  • As diverse online information services are introduced and the use of them are increasing, the importance of the quality control over the online information services is also increasing. Therefore, studies are being attempted to derive quality evaluation models for online information services, but these showed many limitations. In order to overcome the limitations of the previous studies and create more appropriate quality evaluation model, this study analyzed 408 data collected through the interviews with the users of Korea national online information services (NDSL, NTIS) using content analysis and the coding method of ground theory. Through the analysis, we identified the quality evaluation model (13 elements, 6 dimensions) of online information services and the description and insights of each elements. And the priorities of the most significant element(amount of information) and other key elements(such as the usefulness of the information, the diversity of the field, etc.) were figured out through the frequency analysis. Through these inductive methods based on the responses of users, the quality control model could be derived, which is different from the previous researches. This study is the first study which derived the quality evaluation model of online information service through the inductive way based on 408 interview responses from users. Therefore, the results of this study will be helpful to the post researchers who conduct studies on the quality of online information service, etc. Moreover, the results of this study are expected to provide references of frame for decision-making of working-level officials who have to manage the quality of online information services.

  • In case that a closed-form Green's functions are used for the numerically efficient analysis of a general microstrip structures of thin or thick substrate, an efficient technique for the evaluation of MoM off-diagonal matrix elements as well as diagonal elements is proposed. In order to check the validity of the present method, performance is demonstrated for the example of a coaxially-fed microstrip antenna and the present results are compared with the previous results.

  • 본 논문에서는 다양한 형태의 케이블 요소들의 거동이 강사장교의 극한강도에 미치는 영향을 검토하였다. 연화소성힌지 모델을 사용한 극한강도 평가 시 보-기둥 부재의 기하학적 비선형은 안정함수를 사용하여 고려하였고 재료적 비선형성을 반영하기 위하여 CRC 접선계수와 포물선 함수를 사용하였다. 케이블 부재는 새그의 영향이 고려되었다. 연구 결과 등가탄성계수가 반영된 등가트러스 요소를 사용한 경우 강사장교의 극한강도가 케이블 요소 또는 현수선 요소를 사용하여 평가한 극한강도 보다 안전측으로 평가되었다.

  • The purpose of this study is to certify the eco-friendly elements of traditional Hanok based on the G-SEED 2016 Criteria. For this study, estimating the eco-friendly elements of the two traditional Hanok - Myeong Jae's old house and General Lee Sam's old house - based on the G-SEED 2016 Criteria. The results were as follows: Each of the two traditional Hanok can get the sufficient points for grading at G-SEED 2016, but the two required criteria are not be able to get the points; energy performance such as heat storage of traditional mud wall and water saving equipments. On the other hand using eco-friendly materials in traditional Hanok are satisfied with the Material category. Also using rainwater and underwater through garden and pond in traditional Hanok are satisfied with the Ecological environment category. But lots of the other eco-friendly elements of traditional Hanok can not be estimated by G-SEED 2016 Criteria. Modern Hanok will be able to obtain G-SEED 2016 certification when using the valid eco-friendly elements of traditional Hanok and applies new technologies such as water saving equipments.

  • 게임의 멀티미디어 데이터는 그 품질에 따라 게임의 몰입에 영향을 준다. 예술적인 품질은 평가기준을 설계하기가 어렵지만 기술적인 관점에서 평가할 수 있는 부분에 대해서는 평가기준을 설계하는 것이 품질의 신뢰성과 객관성을 확보할 수 있다. 그러나 게임의 멀티미디어 데이터에 대한 품질평가 기준은 아직 설계된 것이 없다. 따라서 본 연구에서는 게임의 멀티미디어 데이터에 대한 품질평가 요소를 추출하고, 추출 요소에 대한 신뢰성을 검증하였다. 그리고 각 요소에 대한세부평가내용을 정의하고, 평가지표를 개발하였다. 본 연구의 결과는 고품질의게임 개발에 가이드 역할을 하며 게임산업의 성장에 긍정적인 영향을 줄 것으로 기대한다.

  • With the diversification and internationalization of the food industry and the increased focus on health from a majority of consumers, food safety policies are being implemented based on scientific evidence. Risk analysis represents the most useful scientific approach for making food safety decisions. Total diet study (TDS) is often used as a risk assessment tool to evaluate exposure to hazardous elements. Many countries perform TDSs to screen for chemicals in foods and analyze exposure trends to hazardous elements. TDSs differ from traditional food monitoring in two major aspects: chemicals are analyzed in food in the form in which it will be consumed and it is cost-effective in analyzing composite samples after processing multiple ingredients together. In Korea, TDSs have been conducted to estimate dietary intakes of heavy metals, pesticides, mycotoxins, persistent organic pollutants, and processing contaminants. TDSs need to be carried out periodically to ensure food safety.

  • 본 연구의 목적은 중국 소비자의 휴대폰 선택 시 고려하는 주요 평가영역에 대한 세부 특성요인의 만족도가 해당 평가영역 만족도에 어떠한 영향을 미치며, 각 평가영역에 대한 만족도가 고객의 재구매의도와 타인추천의도에 어떠한 영향을 미치는가를 사용 휴대폰 유형에 따른 집단별로 분석하는데 있다. 설문조사 시 평가요인으로 가격, 디자인, 품질, 편리성, 기능 그리고 개인적 요인을 설정하였으며, 재구매의도와 타인추천의도로 구분 실시하였다. 연구결과, 가격을 제외한 모든 특성요인이 해당 평가영역의 만족에 유의한 것으로 나타났으며 유의한 경로가 집단별로 차이가 존재함을 알 수 있었다. 또한 모든 집단에서 평가영역에 대한 만족이 재구매의도와 타인추천의도에 유의한 것으로 평가되었다. 연구 결과 우리 기업의 경우 디자인, 기능, 개인적 요인에 관한 특성요인은 평가영역 만족에 유의한 영향을 미치나 해당 특성요인의 만족도는 상대적으로 낮은 것으로 나타난다. 따라서 이들 특성요인에 대한 만족도를 높일 수 있는 품질 개선방안을 강구하여야 할 것으로 사료된다.

  • This study includes a case study among plastic process manufacturing companies, based on which, the currently used 4M method is applied in terms of machine, media, man, and management, to conduct quantitative risk evaluation, and thus to contribute to reducing human and material loss as well as preventing accidents in industrial fields. The result of this study is analyzed based on the 4M-risk assessment to find out the hazardous risk elements, and the quantitative evaluation made it predictable the value of risk(frequency $\times$ intensity) in such classified levels as serious risk, critical risk, and intolerable risk. Further, Among the businesses with hazardous risk elements and high frequency of industrial disaster, risk analysis was conducted for each process, and as a result, 38 cases among 76, including those of serious risk, critical risk, and intolerable risk, were improved, and the risk was reduced. Besides, it is thought that with the engineering approach with 4M-Risk Assessment, the attempt to improve safety level contributes to prevention of accidents.

  • While the operator's working environment employs the digital devices and technology which are not be fully digitalized due to its technical constraints, it has been changed to the hybrid environment in which digital and analog elements are combined. The hybrid environments need to study its characteristics and the guidelines for the proper design and evaluation purpose. This paper describes the characteristics and evaluation guidelines for hybrid environment through studying the characteristics of digital and analog environment based on the related human factor guidelines and literatures. The result of this paper would be applied for the human machine system such as main control room in nuclear power plant working under hybrid environment. And also, it may be applied for the evaluation of the generic human working environment which digital and analog elements are jointly used.
