  • It is time for environmental educators to think about corporations and it is also time for corporations to consider about the environment and EE(environmental education). However there is very little research that discusses the importance of corporation's involvement in EE. Therefore, the purpose of this paper is to review the research of corporate environmental education. The main aim of this paper is to disclose the research trend, result of corporate EE. To do this, environmental education journals and books, published in Korea and oversea, are reviewed. However, there is very little research and are a few articles focused on corporate EE, which mainly conducted in Japan. Furthermore, these articles usually introduce the status and cases of corporate EE. As a results this article analysed that the main themes of the researches of corporate EE are the possibility of corporate EE, the status of corporate EE, the collaboration between school and corporation, the effect of corporate EE, and the limits and challenges of corporate EE. Also some important results of these themes are introduced and discussed for the application in Korea.

  • This paper reviews and summarizes the fuel-cell-related studies those have been recently published in major Korean Citation Index journals, aiming at analyzing the research trend in fuel cell technologies. Six major journals are selected for the literature survey; 57 papers are chosen for the detailed analysis through a screening examination on the total 1,040 papers published during between 2018 and 2020. Papers are classified into six technical categories, such as i) electrode, ii) electrolyte, iii) bipolar plate and stack, iv) fuel cell system, v) balance of plant, and vi) diagnosis-related studies, and summarized by the experts in the relevant area. Through this paper, we provide a comprehensive review on the recent trends and progress in fuel-cell-related research work in Korea.

  • 본 연구에서는 '아파트 가격'과 '인터넷 검색량' 간의 관계를 분석하였다. 선행 논문들이 '공표된 아파트 가격'과 '인터넷 검색량' 간의 관계만을 검정했던 것에 비해, 본 논문은 '공표된 아파트 가격'을 '본질적 가격 요소'와 '일시적 가격 요소'로 구분하여 '본질적 가격 요소와 인터넷 검색량' 간의 관계, '일시적 가격 요소와 인터넷 검색량' 간의 관계에 대해서도 분석했다는 것이 선행 연구들과의 차별적 측면이다. Granger 인과관계 분석 결과를 보면, '공표된 아파트 가격'과 '인터넷 검색량'이 서로 양방향의 Granger 인과관계를 갖는 것으로 나타났다. 선행논문들에서 연구가 이루어지지 않았던 부분으로서, 아파트 가격의 추세 요소인 '아파트 본질적 가격 요소'도 '인터넷 검색량'과 피드백적 관계를 보였다. 그리고 '아파트 일시적 가격 요소'는 '인터넷 검색량'에 대해 선행관계를 갖는 것으로 나타났다. 아파트 일시적 가격 요소도 인터넷 검색량과 관계가 있다는 것은 아파트시장 참여자들의 '일시적 심리적 측면, 과잉반응에 의해 발생되는 가격 요소'도 인터넷 검색량에 영향을 준다는 것을 의미한다. 본 연구 결과는 아파트 가격의 움직임이 시장참여자들의 관심에 영향을 준다는 의미를 제시하며, 부동산시장 분석 등에 있어서 가격의 움직임, 인터넷 검색량과 같은 자료를 활용해야 한다는 의미를 갖고 있다.

  • It is reported that the segmental feature based recognition system shows better results than conventional feature based system in the previous studies. On the other hand, the various studies of combining neural network and hidden Markov models within a single system are done with expectations that it may potentially combine the advantages of both systems. With the influence of these studies, tandem approach was presented to use neural network as the classifier and hidden Markov models as the decoder. In this paper, we applied the trend information of segmental features to tandem architecture and used posterior probabilities, which are the output of neural network, as inputs of recognition system. The experiments are performed on Auroral database to examine the potentiality of the trend feature based tandem architecture. From the results, the proposed system outperforms on very low SNR environments. Consequently, we argue that the trend information on tandem architecture can be additionally used for traditional MFCC features.

  • A holography technique optically reconstructs a three-dimensional object in space to provide a natural sense of depth and volume to the observer, thereby providing an ultimate 3D image capable of solving the problem of "vergence-accommodation conflict" occurring in a conventional stereoscopic imaging system. In this paper, we present a technical framework for measuring the performance and evaluating the quality of a holographic display, which enables a quantitative measurement of the optical and physical properties that affect the performance and quality of a holographic display. In addition, we provide the trend regarding standardization related to holographic display measurements. Although this trend has barely started, research activities related to holographic display measurements and quality evaluations are expected to grow in the near future.

  • This paper analyzes the parallelism between the art trend and the fashion. As a representative case, we consider the Modernism and the Flapper look. The Modernism rejected the tradition of the past and pursued something new. This trend was in parallel with the fashion called flapper look which was against the tradition and made drastic change. The factors which represent the spirit of the age the Modernism are the simplicity, the rejection of the tradition, the individualism and the subjectivity, the functionalism, the fragmentation of the self, and the straight line. We discuss the fashion style of the flapper look in terms of these factors.

  • A typical industrial data - monitoring scheme often requires trend detection Trend detection can be accomplished in many ways. Common statistical methods are the sign test, the run test, and the trend test. Graphical methods include various smoothing schemes and the cusum. The cusum has established itself as an efficient method of detecting changes in the mean level of a process being monitored. The cusum requires a "target value" with which the raw data are compared. At production start - up it is often difficult to designate the target value. This paper offers a means of initiating the cusum technique without a target value.

  • The purpose of this study is to analyze the recent trend color of bathroom based on analysis result of digital color image processing, to analyze the emotional color of that, and to suggest the harmony color combination for the bathroom. It leads to the two final results. That is, the main color of bathroom image is recognized as three color classifications such as YR-Y, Y-GY, PB-P, 2) from the point of emotional aspect, the trend color of the bathroom can be classified into four image categories: 'modern', 'mild', 'elegant', 'natural'. Finally, under these categories, this paper propose 12 color harmony schema which can be applied to color in, especially bathroom Interior design.
