In this paper, the main noise sources and its radiated noise levels of upwind horizontal-axis wind turbines are experimentally and theoretically investigated. Theoretical predictions for indentifying the dominant source locations are made by using the empirical noise prediction model of Brooks et al. (1989) for the airfoil self noise. Through the comparison of theoretical results with the experimental results, turbulence-boundary-layer-trailing-edge (TBL-TE) noise is revealed to be the dominant source over all frequency range and separation and stall (S-S) noise is possibly important in the relative lower frequency range compared with TBL-TE noise.

In this paper, we propose a Transformation-Based Learning (TBL) method on generating the Korean standard pronunciation. Previous studies on the phonological processing have been focused on the phonological rule applications and the finite state automata (Johnson 1984; Kaplan and Kay 1994; Koskenniemi 1983; Bird 1995). In case of Korean computational phonology, some former researches have approached the phonological rule based pronunciation generation system (Lee et al. 2005; Lee 1998). This study suggests a corpus-based and data-oriented rule learning method on generating Korean standard pronunciation. In order to substituting rule-based generation with corpus-based one, an aligned corpus between an input and its pronunciation counterpart has been devised. We conducted an experiment on generating the standard pronunciation with the TBL algorithm, based on this aligned corpus.

An interscale transport of the turbulent kinetic energy (TKE) and Reynolds shear stress (RSS) is examined in an adverse pressure gradient (APG) turbulent boundary layer (TBL). The direct numerical simulation data of an APG TBL at Re_τ = 834 and β = 1.45 is employed. The TKE and RSS transport equations are divided into large and small scales, leading to the introduction of interscale transport. The TKE mainly transfers from large scales to small ones in the outer region, and vice versa for the RSS. An interscale transport of TKE and inverse interscale transport of RSS are amplified by APG, and the latter results in the increase in large scales of TKE production. Some of outer large scales of enhanced TKE transfer to small scales and then dissipate by viscosity, and the remains dissipate turbulent-non-turbulent interfaces by turbulent transport.

Fashion companies confront to environmental problem and resource depletion and have to consider 'sustainability' into their management. Corporate sustainable management of company is explained as the model of Triple Bottom Line which is composed of economic, social and environmental elements, thus we wanted to adapt this model to the case of fashion companies and the purpose of this study is to investigate the relationship among the TBL elements which contain the economic, social and environmental responsibility, the evaluation on fashion company including the reliability, reciprocality and reputation of company, and the evaluation of brand image. We conducted the survey of questionnaire about 300 people in their 20's and performed statistical analysis. As a result, the elements of corporate sustainable management in fashion company are related to the company evaluation, and again company evaluation is correlated to the evaluation of brand image. Economic responsibility of fashion company is related with the reliability of company evaluation, social responsibility of fashion company with the reciprocality and reputation of company evaluation, and environmental responsibility is deeply related with reciprocality of fashion company's evaluation. The results of this study revealed the importance of corporate sustainable management of fashion companies, and the relationships in fashion industry are stronger than in other industry.

본 연구는 성인간호학 분야의 심장계 환자간호에서 팀기반학습 프로그램을 개발하고, 간호학생들에게 적용하여 교과목 학습성과로서 문제해결능력, 비판적 사고성향, 학업성취도, 그리고 수업만족도에 미치는 영향을 확인하기 위해 시도되었다. 연구방법은 비동등성 대조군 전후설계인 유사실험연구이고, G시 4년제 간호학과 2학년 학생들을 편의표집하여 실험군 52명, 대조군 54명을 대상으로, 실험군은 2014년 2학기 중 주당 3시간씩 2주 동안 팀기반학습을 적용하고, 대조군은 동 기간동안 강의 및 사례적용 발표수업을 제공하였다. 연구 결과, 팀기반학습을 적용한 실험군과 적용하지 않은 대조군의 문제해결능력(F=5.92, p=.017)과 수업만족도 점수(F=5.80, p=.018)는 실험군이 대조군 보다 통계적으로 유의하게 높았다. 그러나 비판적 사고성향과 학업성취도 점수는 실험군이 대조군보다 높았으나 통계적인 유의한 차이는 없었다. 이상의 연구결과를 통해 간호교육에 팀기반학습의 적용은 간호학생들의 중요한 학습성과인 문제해결능력에 긍정적인 영향을 미치고, 수업만족도를 높일 수 있음이 확인되었다.

이 논문은 문법적 추론에서 유전자 알고리즘의 진화대상으로 테이블 표현(Tabular representation: TBL)을 이용한 문맥자유 문법(Context-free grammar: CFG)을 학습하는 기존의 방법을 개선하여 더 효율적인 결과를 얻은 그 방법과 실험 결과를 제시한다. 이 논문에서 소개하는 개선된 점은 두가지로, 첫째는 적합도 함수를 긍정과 부정의 예들에 대한 학습 평가를 동시에 반영하도록 수식을 개선하고 둘째는 긍정적 학습 예들로부터 생성된 TBL들에 대응되는 파티션(partition)들을 학습 문자열의 크기별로 분류하여 부류별 진화 과정을 진행하며 그 성공률에 따라 구성 비율을 조정하여 다음세대에 생존에 연계하는 학습 방법을 적용한다. 이 개선점들은 학습 예들의 크기에 따른 TBL의 크기가 여러 개체들 사이의 교배와 일반화 단계에서 복잡성과 어려움을 해결하여 기존 방법보다도 좋은 효율을 제공한다. 이 연구는 기존 방법에서 제안된 언어들로 실험하고 그 결과는 기존 방법보다 같은 성공률을 갖는 상태에서 학습 완성의 평균 세대수가 적게 걸리는 다소 빠른 세대속도의 결과를 보여준다. 앞으로 이 방법은 확장된(extended) CYK에 시도할 수 있으며 더 나아가 좀 더 복잡한 파싱 테이블(parsing table)에도 적용할 가능성을 제시한다.

This research aims to explore the relationships between 'teamwork skills' (often called team activity competence) and 'thinking styles' of engineering students in Korea, and to provide an explanation for the application of team-based environment as well as for the increase of teamwork skills. Teams and team activity are pervasive in today's organization and there has been relatively much research on teamwork skills and its related factors. However, to date, little attention has been paid to the teamwork skills, essential factor in team-based environment and its relationships with thinking styles. This study was conducted with 383 engineering students at P University, and students' teamwork skills as well as thinking styles have been measured before and after team-based learning class (hereafter TBL). Our findings show that firstly, there was a significant increase of teamwork skills between before and after TBL class. Second, team activity competence was found to have a higher correlation with most of creativity generating styles (i.e. legislative, judicial, hierarchical and global styles). Third, hierarchical style was found to influence team activity more than other components, and also legislative, external, global and judicial styles contributed to team-based activity. These findings are expected to provide an explanation for the application of thinking styles in team-based environment and will be useful for the improvement of related courses in engineering school.

Purpose: This study was to evaluate the effects of a blended-learning based bioethics program on perceived ethical confidence, critical thinking disposition, moral sensitivity, and academic self-efficacy of the nursing students living in S city. Methods: The program was conducted 13 sessions (2 hours/session) and evaluated for perceived ethical confidence, critical thinking disposition, moral sensitivity, and academic self-efficacy. The collected data were analyzed with descriptive statistics and paired t-test using the SAS 9.4 program. Results: The blended learning based bioethic program was found to be effective for perceived ethical confidence (t=8.70, p<.001), critical thinking disposition(t=8.96, p<.001), moral sensitivity (t=6.43, p<.001), academic self-efficacy (t=20.5, p<.001), and program satisfaction(t=4.92, p<.001). Conclusion: The results of this study suggest that a blended learning program including TBL has advantages of case-based discussion and active interaction for nursing students' bioethics education.
