  • With the rapid development of China economy, many engineering projects with large scale and investment were constructed in China and some were the biggest ones in the world. With the development of engineering practice, great progress in the research of engineering management of China was made and a large number of research findings were embodied in content of research papers and were represented by technical words. To know the state of arts in the research field of engineering management in China, three major parts, namely title, abstract and keywords of research papers in last five years from three representative Chinese journals about engineering management were chose as research materials. Unlike western languages, there are no delimiters between the words of Chinese, so the maximum matching and frequency statistics (MMFS) method, a text segmentation technique of text mining Chinese, was presented to extract the features consisting of technical words, phrases and words from the research materials. Recent research and developing trend of engineering management in China were found by comparing and analyzing the difference of technical words in the research materials of last five years.

  • In order to cut the round bale easily, a roughage cut-feeder for the round bale was developed in this study. This study consists of two parts. One is development of a cutting mechanism and a performance test reported in the previous paper. This is the second part of the study. For the study, recent trend of traditional cutting system was analyzed. Also, cost of the prototype cut-feeder was analyzed and determine the break-even point of farm size was determined by comparing with traditional method using a traditional cutter. A prototype cut-feeder was investigated with the fact that working performance, fiber length and shape of roughage and feeding quality was good. Operating cost of the prototype cut-feeder decreased rapidly with an increase of farm size. Break-even point in terms of farm size was 36 heads for beef and 28 heads for dairy. Also, costs estimated were 118,000 won/head year and 148,000 won/head year, respectively.

  • The way we live on our own is distinguished from those of the other countries while the society changes rapidly globalized with the flow. It is called housing culture when culture is discussed in dwelling, what contains living. With the beginning of building Mapo Apartment in 1962, apartment has become the most popular type of housing and currently is provided more than 50% of housing unit in Korea. Even though it has been criticized for a problem of standardization in its form and social issues, its provide increases in its number and its types become hilghly diversified in construction. Therefore the housing culture of apartment should be accepted as a characteristic of our society and it's time to find the identity of our housing culture and make a progress in it. Studies related to apartment are also increased in its number and diversified in its range. The purpose of this study is to go through the trend of studies related to apartment and to analyze subject and content changes according to politic, social and economic changes for the recent 10 years. The study would provide the basic research material related to apartment both to academic area and companies in the future.

  • The interaction between technology and tourism has been a dynamic research area recently. This study aims to review the progress and development of technology in tourism research via a bibliometric analysis. We derive the source data from the Web of Science (WoS) core collection and use CiteSpace for bibliometric analysis, including countries, institutions, authors, categories, references, and keywords. The analysis results are as follows: i) The number of published articles on the role of technology in tourism has increased in recent years. ii) Technology-related articles in tourism are abundant in Tourism Management, Journal of Travel Research, and Annals of Tourism Research. iii) The countries with the most contributions are China, the US, and the UK. The most active institutions are the Hong Kong Polytechnic University, University of Central Florida, Bournemouth University, University of Queensland, and Kyung Hee University. iv) The reference analysis results identify eight extensively researched topics from the most cited papers, and the keyword burst analysis results present an emerging trend. This study identifies the effect and development of technology in tourism research. Our findings provide implications for researchers about the current research focus of technology and the future research trend of technology in the tourism field.

  • 빠르게 변화하는 사회 구조와 생활환경 안에서 다양해진 소비자의 욕구를 충족시키고 제품이 갖는 독특한 캐릭터를 창출하기 위해서, 현대의 디자이너들은 보다 새로운 아이디어를 지속적으로 시도해야만 하게 되었다. 지난 20세기는 기술의 획기적인 진보와 더불어 산업화로 인한 다양한 측면에서 디자인의 성장이 이루어졌고, 시대의 흐름에 따라서 그 의미와 스타일이 각기 다른 양상으로 변화되어 왔다. 과거에 유행했던 디자인과 스타일을 차용하여 현대적 의미와 개념의 디자인으로 재창조하는 레트로(Retro) 디자인이 최근의 디자인 트렌드로 확산 적용되고 각광받고 있다. 이러한 복고적 스타일의 현상은 다양한 분야에서 과거를 회상하게 하는 이미지로 나타나고 있으며 새로운 감각으로 또 다른 가치로 인정받고 있다. 제품디자인 측면에서 가장 대표격인 자동차 디자인은 지난 100여 년 간의 스타일의 변천사에 있어서 시대적 사회·문화적인 변화와 기술의 진보에 의하여, 점차 다른 형태로 나타났으며 다양한 디자인이 끊임없이 시도되어 왔다. 최근의 자동차 스타일의 흐름은 첨단과학기술의 비약적인 성장으로 인해, 그 스타일의 변화가 빠르고 다양한 형태로 나타나고 있는 반면에, 과거의 디자인을 재 도입하는 레트로 스타일이 새로운 트렌드로 관심을 끌고 있다. 자동차디자인에 있어서 복고적 스타일의 의미는 트렌드 이전의 인간의 감성을 자극하고 인간성 회복이라는 또 다른 차원에서, 과거의 문화와 자신과의 연결을 회복하는 의미에서 현대적 감각으로 재창조되어, 향후 미래 디자인 영역을 확장시킬 것으로 보이며 새로운 디자인 트렌드로 발전을 예측할 수 있다.

  • There are many previous review articles are available to summarize either the characterization methods of effluent organic matter (EfOM) or the individual control treatment options. However, there has been no attempt made to compare in parallel the physicochemical treatment options that target the removal of EfOM from biological treatments. This review deals with the recent progress on the characterization of EfOM and the novel technologies developed for EfOM treatment. Based on the publications after 2010, the advantages and the limitations of several popularly used analytical tools are discussed for EfOM characterization, which include UV-visible and fluorescence spectroscopy, Fourier transform infrared spectroscopy (FTIR), size exclusion chromatography (SEC), and Fourier transform-ion cyclotron resonance-mass spectrometry (FT-ICR-MS). It is a recent trend to combine an SEC system with various types of detectors, because it can successfully track the chemical/functional composition of EfOM, which varies across a continuum of different molecular sizes. FT-ICR-MS is the most powerful tool to detect EfOM at molecular levels. However, it is noted that this method has rarely been utilized to understand the changes of EfOM in pre-treatment or post-treatment systems. Although membrane filtration is still the preferred method to treat EfOM before its discharge due to its high separation selectivity, the minimum requirements for additional chemicals, the ease of scaling up, and the continuous operation, recent advances in ion exchange and advanced oxidation processes are greatly noteworthy. Recent progress in the non-membrane technologies, which are based on novel materials, are expected to enhance the removal efficiency of EfOM and even make it feasible to selectively remove undesirable fractions/compounds from bulk EfOM.

  • Objectives: FCTC is the first international convention in public health field. Global progress report is about the implementations of the FCTC that are conducted with comparison and analysis for recent trend of tobacco control policies and convention performances on the global level. Methods: By conducting literature review related to tobacco control, expecially through reviewing Implementation of the WHO FCTC GPR(2014), this report compared and analyzed Korea's status of tobacco control based on tobacco control policy in every member state. Results: As a result of the comparison of FCTC to Korea's tobacco control policy, for the first, the most outstanding article that has been peformed continuously is Article 8, 12, 14. Secondly, the policy that has been partially renovated and reinforced is Article 6, 9, 10, 11, and for the last, the policy that has no progress and needs improvement is Article 13. Conclusions: For improvement in Korea's tobacco control policy in the future, first, betterment in policies on categories about advertisements, promotions, sponsorships on tobacco products that passed FCTC commitment period is required along with the modifications of FCTC related laws and reinforcement of the policies, and development of national core competence for an effective implementation of the convention.
