In this study, we propose a methodology for predicting the movie audience based on movie information that can be easily acquired before opening and effectively distinguishing qualitative variables. In addition, we constructed a model to estimate the number of movie audiences at the time of data acquisition through the configured variables. Another purpose of this study is to provide a criterion for categorizing success of movies with qualitative characteristics. As an evaluation criterion, we used information gain ratio which is the node selection criterion of C4.5 algorithm. Through the procedure we have selected 416 movie data features. As a result of the multiple linear regression model, the performance of the regression model using the variables selection method based on the information gain ratio was excellent.

최근 국내의 설계시공일괄방식(이하, 일괄방식)은 설계시공분리방식(이하, 기타방식)에 비해 높은 초기투자비용으로 인하여, 효용성에 대한 의문이 지속되고 있다 한편 발주방식별 성능을 평가한 기존의 연구를 살펴보면, 일괄방식은 공기측면과 품질측면에서 기타방식에 비해 우수한 것으로 보고되고 있다. 비교적 정량적 평가가 가능한 공기측면의 성과와 달리, 품질 측면의 성능은 해당 시설물의 발주자와의 면담을 통하여 만족도 수준을 평가하는 정성적인 평가가 대부분이다. 따라서 이 연구에서는 기존의 연구와는 달리, 2000년 이후 일괄방식과 기타방식으로 발주된 교량계획에 대한 성능수준을 평가하기 위하여, 설계도서 중심으로 계획성, 시공성, 유지관리성 등의 측면에서 평가해 보고자 한다. 이를 통하여 실제로 발주방식별 품질 등의 성능 측면에서 발주방식별 성능수준의 차이를 도출하였다.

최근 4차 산업으로의 산업 패러다임의 변화가 이미 시작되었으며, 이러한 4차 산업 시대에 무형 지식재산인 특허의 중요성은 날로 증대되고 있다. 특허의 기술가치평가는 전문가의 의견에 따라서 산정되기 때문에 많은 비용과 시간이 소모되므로 비전문가들의 주관적인 의견에 기인하여 특허의 질적 수준을 판단하게 된다. 따라서 특허의 질적 수준에 대한 객관적이고 합리적인 평가 체계 개발이 필요하다. 본 논문에서는 특허의 가치평가를 기술성, 권리성, 활용성으로 구분하고 베이지안 구조방정식을 사용하여 특허의 정량화되고 객관적인 평가 모델링에 대해 고려하였다. 특히, 한국발명진흥회에서 수집한 자료를 토대로, 직접적으로 측정되기 어려운 질적 성과들을 모형화하고 평가하는데 탁월한 구조방정식과 사전 정보를 활용함으로써 작은 표본 하에서도 안정적인 모형화가 가능한 베이지안 접근법을 함께 적용하여 특허 평가 모형을 개발하였다.

본 연구에서는 고층건물 구조시스템의 다양한 대안으로부터 이들의 성능을 합리적으로 평가하는 방안을 제안하였다. 대안평가는 업무절차에 따라 예비평가, 본평가, 실시평가로 나누어 수행된다. 대안평가를 위한 평가범주는 구조성능, 경제성, 공기의 세 가지로 구성되고, 각 평가범주는 이들을 평가하기 위한 세부 평가항목으로 구성된다. 예비평가에서는 경험지식에 의한 정성적인 평가를 수행하며, 본평가와 실시평가에서는 수치적인 결과를 바탕으로 주로 정량적인 평가를 수행한다. 평가결과의 종합화는 평가항목들간의 관계가 선형적이라는 가정하에 가중평균법을 적용하였다. 제안된 대안평가 방안은 실무예제에 대한 시뮬레이션을 통하여 그 적용성을 검토하였다.

일반적인 사회기반시설물 자산관리 절차는 기존 자산의 명확한 정보획득, 서비스수준의 설정, 요구수준의 분석, 재정상태와 가용예산의 분석, 자산관리 계획의 준비, 수정된 자산의 정보 획득 순으로 구성될 수 있다. 본 연구에서는 실제적인 위험도분석 기반의 개선된 교량 자산관리를 위하여 필요한 상태평가 및 성능측정, 성능척도의 설정, 파손형태 및 위험도 분석 등에 대한 방법론을 제시하였다. 보다 효율적인 교량 관리를 위하여 위험도 고려가 필요한 교량 기본현황정보 및 성능척도 항목을 설정하였고, 정량적 정성적 위험도를 고려한 성능평가방법을 제안하였다. 위험정도와 발생가능성을 고려한 위험도 매트릭스를 이용한 성능평가방법은 교량의 서비스수준을 보다 합리적으로 추정할 수 있다. 제안된 위험도분석 절차와 방법이 접목된 교량 서비스수준 평가방법을 이용하면 보다 합리적인 자산관리 의사결정이 가능하며, 향후 최적의 유지관리 의사결정을 위한 자산관리 체계구축 및 시스템 개발에 기여할 수 있을 것으로 판단된다.

Purpose: The purpose of this study was to identify and assess from nursing students and nurses in the clinical field what constitute good instruction, through the review of nursing students' opinions and clinical field demands. Methods: The study design was used Creswell's exploratory sequential design by collecting and analyzing qualitative data obtained from interviews and then analysis of quantitative data. The participations were 79 seniors in nursing schools and 85 nurses with less than three years of clinical experience. The data were collected through individual interviews and analyzed based on Elo and Kyngas's content analysis method. The quantitative data were collected using the questionnaire developed based on qualitative results and analyzed by SPSS 23.0 program and Importance Performance Analysis (IPA). Results: The results showed that IPA extracted seven items with high importance but low satisfaction: "nursing fads and trends," "teacher-learner communication and reflection," "materials used in clinical settings such as monitoring results and test results," "special presentations by experienced practitioners," "instruction assures learners' comprehension," "accurate and detailed evaluation standards" and "feedback on homework and exam." Conclusion: The factors comprising good instruction were verified, and the necessity for additional efforts to improve high importance and low performance factors was noted. Therefore, this study can serve as a guide for nursing education facilities and educators in developing of a thorough education system with excellent instruction designed to achieve an ideal nursing education.

Purpose of this study is to supply data that need in qualitative improvement and plan for middle class through a post occupancy evaluation by the tenants in the rental apartment of national housing size. The results of this study are as follows; 1) Characteristic of household differ as the size tenants live in at present. But, usually characteristic of household was family life cycle was from child-rearing time to secondary education time, a family's number was 3${\sim}$4 person, and income per month was 1${\sim}$3 million won. 2) The satisfaction of whole and physical environment were satisfied more than average 3 points. However, the satisfaction of economic performance and administration environment were dissatisfied by average 3 points low. 3) Factors that affect in housing satisfaction were administration environment, the housing size, a family's number.

The ripple effect is analyzed in the post-construction evaluation phase, but only the qualitative analysis and simple numerical fluctuations are analyzed, thus, no reliable ripple-effect analysis has been conducted. Therefore, in this study, a focus group interview was conducted with 10 experts to propose a plan to improve the ripple effect metrics. Consequently, by linking with the policy-effect metrics of the pre-feasibility study, it is expected that the utilization of the analysis results will be improved and objective and quantitative analysis will be possible.

Purpose - This study aims to suggest appropriate policies and performance indicators for financial aid recipients. It analyzes the existing regular government policy funds support project, especially its propriety and reasonability. Research design, data, and methodology - When financial aid is effective, it should be able to predict small enterprise business results. Additionally, there should be an evaluation, checking before and after performance rates so that the rate of achievement and outcome can be measured. This study's contribution for small enterprises is in researching the best way to improve this support system. Results - The Small Enterprise and Market Service (SEMAS), currently designated as a support organization for implementing the government financial aid project, has assessment indicators. However, these focus mainly on quantitative indicators and survey results. Conclusions - In the future, there is some need to draw up measures, setting the right direction for developing policies for the small enterprise fund loans and improving the management of the plans. Eventually, this effort will dispel concerns about the present support policy, which is considered to be weakening small enterprises.

With the development of industrial technology and science, production and manufacturing facilities have been enhanced and improved, and the importance of the safety of workers has also been regulated and limited by various safety management methods. As a way to secure the safety of the workers from the production facility, the fail-safe and fool-proof methods are now being applied. Any possible insecure behavior and unsafe conditions can be removed by adopting the standards and specifications that are now secure the safety of workers and equipment. This research analyzes EN ISO 13849-1 international and European standards during CE certification. In order to secure acceptable reduced risks, the risk assessment process of ISO 12100 and the processes for reducing its risk are applied. In the current ISO 13849-1 standard, the criteria for the required performance level PLr (Required Performance Level) for the applicable risk and safety functions through the risk assessment are subjective and not subdivided. Therefore, the evaluation criteria are likely to cause judge's judgement error due to qualitative judgement. This research focuses on evaluation and acceptable performance level setting for the safety circuit of the equipment. We propose an objective and specific evaluation criteria to secure safety, and the proposed evaluation criteria are applied to the case study of the safety circuit for the equipment. In order to secure the safety of the entire safety circuit, the improvement of the MTTFd and DC level related to the SRP/CS (Safety-Related Parts of Control Systems)' lifetime is required for the future research.
