본 논문은 사용자의 피부 상태에 따라 사용자에게 적합한 화장품을 소개해주는 화장품 추천 웹 쇼핑몰, "PBTI"를 개발한다. 요즘 유행하는 성격 유형 설문조사인 MBTI에서 영감을 받아 피부 유형과 퍼스널 컬러를 검사하고 이를 기반으로 화장품을 추천하는 온라인 쇼핑몰 웹사이트를 제작하게 되었다. 바우만 교수의 피부 유형 지표를 바탕으로 제작된 질문을 통해 사용자들의 피부 유형을 검사하고 해당 피부 유형 결과에 따른 상품을 추천해주는 알고리즘이 탑재되어 사용자에게 맞는 상품을 추천해준다. 텐서플로우 기반의 인공지능을 탑재하여 퍼스널컬러 테스트를 제작하였다. PBTI의 이러한 무료 테스트 서비스 제공은 다른 온라인 뷰티 쇼핑몰과 극명한 차별점을 만들고, 쇼핑몰 매출을 크게 증대시킬 것으로 기대한다.

In recently, one of the most interests is a field related with serious game. Most game users perform the first for the executing of tutorial before they use a serious game for the first time. But in most case, developers do not recognize importance of tutorial and they do not consider the type of user preference tutorial and make tutorials only as developer's intentions. In our study, we carry out investigation and analysis about type of providing tutorials in representative serious games. Also, we do a survey of users' preferences for types of tutorials. If developers use the result of our study and we can expect more convenient and good quality of tutorial development.

도시하천은 Eco-network의 근간이며, 하천을 통해 인간이 느낄 수 있는 정서적인 안정감, 친밀감, 쾌적함 등 어메니티의 모체로서, 최근 도심내 Open space로서의 위상을 높여가고 있다. 양재천을 위시하여 수원천, 전주천 등 지역을 대표하는 하천들이 자연형 하천으로 정비되어 하천 이용에의 관심이 고조되고, 청계천의 성공을 기점으로 하천의 친수공간으로서의 기능이 강조됨에 따라 도시하천에 대한 개발 요구도는 급속히 높아지게 되었다. 이러한 개발요구의 급속한 증가가 있음에도 불구하고 보전과 이용이 상충하는 도시하천의 어메니티 향상을 위한 기준은 마련되지 않고, 일부 하천에서 이용과 관리의 효율성을 고려하지 않은 무분별한 개발을 부추기게 되어, 오히려 어메니티 향상의 측면에서는 부정적인 결과를 초래하였다. 따라서 본 연구에서는 하천 특성에 적합한 어메니티 도입 기준을 설정하기 위하여 하천의 규모, 자연도, 이용지수를 기준으로 하천유형을 분류하였으며, 이를 바탕으로 지속적인 연구를 진행하여 선진사례와 국내하천조사를 통해 지표요소를 분석하고, 분석된 지표요소에 따라 유형을 추출해내는 과정을 통해 하천유형과 활동유형, 도입시설간의 관계를 설정하여 도시하천 어메니티 향상을 위한 기준으로서 하천복원모델(안)을 제시하고자 한다.

We develop a diagnostic system to monitor failures in an engine-assembly line. Existing techniques such as sensory analysis, time domain analysis, frequency analysis, and statistical analysis have limitations in the diagnosis of engine-assembly failure when there are abnormal vibration waveforms (crashing and damping signals) during the assembly. We use a wavelet technique to deal with crashing and damping signals. We also implement a new technique for developing diagnostic rules from sensor data, and we demonstrate its validity.

소프트웨어 개발 초기 단계에서 소프트웨어 개발비용을 정확하게 예측하는 것은 프로젝트의 성패를 결정짓는 중요한 요소이다. 정확한 예측을 위해서는 빠르게 변화하는 개발 환경 및 기술 변화에 따른 변경 요인을 비용 산정 과정 시 반영시켜야 하며 이를 위해서는 비용 산정 과정 시 적절한 보정계수 선정과 보정계수 값 적용이 중요시된다. 이에 본 논문에서는 어플리케이션 유형 보정계수 개선을 위하여 어플리케이션 유형을 새로 분류한 후 AHP 기법을 적용하여 보정계수를 유도하였다. 또한 개발언어 보정계수 유도에서는 프로그래밍 언어 레벨을 이용하여 프로그래밍 언어별 보정계수를 새롭게 유도하여 보았다. 향후 연구 과제로는 새롭게 제안된 어플리케이션 유형 분류 및 보정계수와 프로그래밍 언어 레벨을 적용한 개발 언어 보정계수를 실제 데이터에 적용하여 비용 예측의 정확도가 얼마나 향상되었는지 검증하고자 한다.

Along with the increased significance of SW education in the 2015 revision curriculum, SW education using various educational methods and tools is being performed, and teaching and learning contents using SW education tools are continuously being developed. In this paper, we analyzed pre-service teachers' EPL contents preference types, preferred development subjects, and their relationship with pre-service teachers based on the analysis conducted after their EPL class session in which its results were assortatively analyzed by department, letter grade, and type. The result signified a clear difference in development subject and types among the departments, and it also showed a difference in development subject and its recipients among the types. However, there was no difference between development subject and type among the letter grade. This will provide a feedback on EPL classes and help develop EPL-related curricula as well as its application.

지금까지 국가연구개발사업은 체계적인 기술 확보전략이 없었다. 본 연구는 국가연구개발 사업도 기술확보 전략이 있어야 한다고 주장하면서, 국가연구개발사업에 적용할 수 있는 기술확보 의사결정프로세스를 제안한다. 국가연구개발사업은 자체개발(insourcing)과 해외위탁/용역, 라이센스, 공동연구의 외부기술(out-sourcing)으로 유형을 구분하였으며, 이에 적합한 기술확보 유형결정을 위한 다단계 의사 결정프로세스를 제시한다.

This study applies Q methodology that can extract subjective opinion or recognition structure for each single household whose Meal Kit products developed and marketed by catering companies according to the demographic structure that changes socially. Implications were analyzed. As a result of subjective recognition type analysis in this study, four types were derived, and each type was named according to its specificity as follows. Type 1 (N = 6): Appearance Assessment Purchase Type, Type 2 (N = 6): Price Comparison Purchase Type, Type 3 (N = 10): Brand Trust Purchase Type, Type 4 (N = 2) : Easy Cooking Purchase Type was analyzed for each unique feature type. In this study, we analyzed the subjective opinion or recognition structure of single-person households whose Meal Kit products are the main demand groups, and suggested the direction and improvement measures for future food product development and launch for single-person households through the analysis by type. The purpose of this study is to provide academic implications based on the analysis results.

This study is to identify the types and meaning of 'Good Leisure' that married immigrant women perceived. 32 Q samples were extracted from the interviews and questions and 40 immigrant women were selected as P samples. The conclusion are as follows; First, the types of 'Good Leisure' were classified as 4 types. Second, the type 1, 'Psychological Stability Pursue Type' recognizes 'Good Leisure' when they feel comfort and relaxed through activities. The type 2, 'Emotional Stability and Self-development Type' recognized 'Good Leisure' when they are pleased, or engaged in self-development activities. The type 3, 'Practical Use Pursue and Information Acquisition Type', recognizes 'Good Leisure' when they learn things necessary for living with less cost, and type 4, 'Acculturation and Exchange Type' recognizes 'Good Leisure' when they learn Korean culture or interact with Korean people. Third, regardless of each type, married immigrant women perceived in having a good time with people as 'Good Leisure'.

This study applied the Q methodology to analyze the subjective evaluation and recognition patterns of elderly women's clothing preferences. For the type 1, knitted materials and natural materials were preferred, and pastel colors were preferred. The type 2 preferred pants that cover the body shape, look young, and have good simple activity. The type 3 was a type in which the waist was treated with a rubber band, the clothes were comfortable to wear and the loose style was preferred. The type 4 was simple and prefers a style with a raised neck and no fasteners, and a clothes that was comfortable to wear. Type 5 was a type that prefers a style that looks important and colorful and youthful in design or color. In order to develop ZIGTECHnology apparel for older women, it is necessary to develop a design that can look aesthetically beautiful while covering the body shapes such as bending of the back and bending of the waist by reflecting the preferences of the older women. It is considered that it is necessary to develop clothing that takes into consideration movement functionality without obstacles to movements in consideration of changes in behavior and movement of hands.
