Advancement in electronic technology has given office workers a new freedom, and a new meaning to workplace flexibility. Actually non territorial workplace has different space elements from general and conventional workplace in terns of interior design and architecture even organization management. The purpose of this study is on the establishment of an evaluation model for non territorial workplace that may be used, practically on the spot. For the establishment of non territorial workplace evaluation model, it is ahead of the study of the feature and the type of none territorial workplace and the research for existing office evaluation technique by Preiser and Vicher. And then the evaluation model for none territorial workplace which is composed three parts that is user's importance, provider's importance and user' satisfaction related fact of workplace. It is constructed by 6 factors which are physical, psychological, workplace environmental, communication, exterior environment, and space managing system therefore each factors has scrupulous elements therefore the total elements are 40. To make more confidence the evaluation model for non territorial workplace, it requires that study continually through the survey with the non territorial workplace evaluation model.

In the IoT environment, there is a huge amount of heterogeneous devices with limited capacity. Existing trust evaluation methods are not adequate to accommodate this requirement due to the limited storage space and computational resources. In addition, since IoT devices are mainly human operated devices, the trust evaluation should reflect the social relations among device owners. There is also a need for a mechanism that reflects the tendency of the trustor and environmental factors. In this paper, we propose an adaptable trust evaluation method for SOA-based IoT system to deal with these issues. The proposed model is designed to minimize the confidence bias and to dynamically respond to environmental changes by combining direct evaluation and indirect evaluation. It is expected that it will be possible to secure trust through quantitative evaluation by providing feedback based on social relationships.

본 연구는 종합뉴스 채널인 KBS, JTBC, YTN를 대상으로 뉴스의 앵커 평판과 브랜드 자산 평가가 뉴스의 지속적 시청 의도에 어떤 영향을 미치는지를 검증하였다. 자료 수집은 각 채널별 뉴스를 시청하고 있는 전국 성인남녀 539명을 대상으로 하였으며, 앵커 평판과 뉴스 브랜드 자산 평가 요인의 영향력을 분석하기 위해 위계적 회귀분석을 실시하였다. 연구 결과, 첫째, KBS는 남성, 저학력, 보수 성향, 시청 빈도가 높을수록, 앵커 인지도와 뉴스 인지도, 뉴스 선호도가 높을수록 뉴스를 지속적으로 시청할 것으로 나타났다. 둘째, JTBC는 진보 성향, 시청 빈도가 높고, 앵커 신뢰도와 뉴스 인지도, 뉴스 선호도, 뉴스 품질에 대한 평가가 높을수록 뉴스를 지속적으로 시청할 것으로 확인되었다. 셋째, YTN은 시청 빈도가 높고, 앵커 신뢰도와 매력도, 뉴스 선호도와 품질에 대한 평가가 높을수록 뉴스를 지속적으로 시청할 것으로 확인되었다. 본 연구는 '뉴스 브랜드 자산'이라는 개념을 정립하였으며, 지상파TV와 종합편성채널, 보도전문채널을 대상으로 앵커 평판과 뉴스 브랜드 자산의 영향력을 평가한 최초의 연구라는 학술적 의미가 있다.

본 연구에서는 확률과 신뢰성을 바탕으로 개발된 FEMA-355F의 내진성능 평가기법을 적용하여 철근 콘크리트 모멘트골조 건물의 내진성능을 평가하였다. 철골 구조물을 대상으로 개발된 FEMA의 성능평가 방식을 다른 구조 시스템에 적용할 때 각 시스템에 적합한 성능값을 결정해야하며, 요구값과 성능값 계산 시 수반되는 불확실성을 반영하는 계수들을 새로이 구해야 한다. 이를 수행하기 위해 예제 건물을 IBC 2003에 따라 설계한 후, 성능평가에 필요한 변수들을 결정하기 위해 건물의 위치에 적합한 지반운동을 이용하여 비탄성 동적 해석을 수행하였다. 해석결과에 따르면 계산된 성능값의 분포는 요구값에 비해 상대적으로 작았으며, 이 결과는 본 연구에서 결정된 성능값이 합리적임을 나타낸다. 구해진 신뢰도는 부분 및 전체 붕괴 모두에 대해 목표치를 초과하였으므로 예제 건물은 목표 성능을 만족하는 것으로 나타났다.

The purpose of this study is to find student factors associated with the students' evaluation of university teaching, and to provide a meaningful reference to policy-making of teaching evaluation. Based on the surveyed questionnaires from 232 students who participated in e-learning course. in combination with applying descriptive statistics, this study analyzes (1) the influences of students' pre-motivation level of student based-on ARCS theory on class satisfaction, (2) the influences of students' grade, attendance, and class involvement on class satisfaction, and (3) the influences of e-learning experience on students' pre-motivation level and class satisfaction. Result of this study shows that: (1) students' pre-motivation level including Attention(A), Relevance(R), Confidence(C), and Satisfaction(S) is positively correlated to students' evaluation for teaching, (2) students' grade, attendance. and class involvement are positively correlated to students' evaluation for teaching, and (3) students' e-learning experience is not related with students' pre-motivation level, whereas it is related with class satisfaction.

Web-based services have fundamentally confidential problems due to characteristics of internet environment such as anonymity. These problems are serious obstacles to grow the web-based services. The security and confidence of web-based services rely on both service provider and users' opinion. But the former has difficulty in trusting the service provider and the latter takes too long time to propagete all users after converging their opinion. Therefore it is necessary to establish the objective and confidential evaluation and certification program for web-based service. In this paper, the internal and external web-based services evaluation and certification programs are compared and analyzed. The critical factors and evaluation methodology for secure and confidential web-based service are identified. Finally, this paper provides the improvement and strategy for web-based services evaluation and certification program.

This paper describes the methods for calibration and evaluation of the relative expanded uncertainty of a multi-axis force/moment sensor. In order to use the sensor in the industry, it should be calibrated and its relative expanded uncertainty should be also evaluated. At present, the confidence of the sensor is shown with only interference error. However, it is not accurate, because the calibrated multi-axis force/moment sensor has an interference error as well as a reproducibility error of the sensor, etc. In this paper, the methods fur calibration and for evaluation of the relative expanded uncertainty of a multi-axis force/moment sensor are newly proposed. Also, a six-axis force/moment sensor is calibrated with the proposed calibration method and the relative expanded uncertainty is evaluated using the proposed uncertainty evaluation method and the calibration results. It is thought that the methods fur calibration and evaluation of the uncertainty can be usually used for calibration and evaluation of the uncertainty of the multi-axis force/moment sensor.

Purpose. The purpose of this study was to investigate effects of preclinical OSCE(Objective Structured Clinical Evaluation) on knowledge, confidence in their Core fundamental nursing skills and self-efficacy in nursing students. Method. The research design was a one group pretest-posttest design and it was done to assess changes in knowledge, confidence in core fundamental nursing skills and self-efficacy from pre to the post-test which was given after the OSCE. Data were collected from March 5 to April 7, 2016 from 37 nursing students who were taking the 15-hours using OSCE learning module at one Gyeongbuk-do, P-city. This practicum was composed of 4 core fundamental nursing skills and 5 other fundamental nursing skills. The knowledge consisted of a 10-item by researchers and the confidence of core fundamental nursing skills consisted of an 9-item NRS and the self-efficacy consisted of a 17-item 5-point scale and measured in both the pretest and posttest. The collected data were analyzed with SPSS IBM 20.0 program for the frequency, percentage, x2-test, and paired t-test. Rusult. The results showed that although scores of knowledge of OSCE learning module were significanlty increased from 5.22 to 7.03(t=5.30, p<.001). There were significantly increased in scores of confidence in core fundamental nursing skills from 5.13 to 7.27(t=10.01, p<.001), In the sub-scales of each core fundamental nursing skills was scored the highest. otherwise, there was no significant difference in self-efficacy(t=1.42, p=.161). Conclusions. Based on the results, this study suggests that OSCE module development activities for nursing students in nursing education-learning in order to improve nursing skills.

본 연구는 간호학과 졸업학년 학생이 임상실습시 경험한 핵심기본간호술 수행빈도, 수행자신감, 수행능력을 확인하고 이들의 관계를 규명하기 위한 서술적 조사연구이다. 연구대상자는 227명으로 자료수집 기간은 2015년 10월 15일부터 10월 28일까지이다. 연구결과 임상 실습시 10회 이상 해보았다고 응답한 항목은 활력징후였으며 전혀 해보지 못했다고 응답한 항목은 수혈, 관장, 기관절개관 관리 순 이었다. 평가 전 수행자신감은 활력징후가 가장 높고 수혈이 가장 낮았으며 평가 후 수행자신감은 근육주사가 가장 낮았다. 수행능력은 산소요법이 가장 높게 측정되었고 근육주사가 가장 낮게 측정되었다. 수행빈도는 수행자신감(r=0.414, p<.001) 및 수행능력(r=0.322, p=.007)과 유의한 양의 상관관계가 있었다. 또한 수행자신감과 수행능력은 유의한 양의 상관관계가 있다고 분석되었다(r=0.281, p=.003). 본 연구결과 임상실습이 비침습적이며 단순측정을 하는 위주로 되고 있으며 수행빈도가 적은 항목이 수행 자신감이 낮으므로 이들을 보완할 수 있는 융복합적 교육방법이 요구된다.
