  • This study carried out an experiment to find out the reaction of hairtail, Trichinus lepturus to the colors of LED light as a basic study on the development of the trolling gear and a method to enable the day-night operation. We used hairtails caught around Seongsan-po, Jeju Island by set nets and hairtail angling. The seven hairtails of the average length 68.9 cm (SD 9.2 cm) and the average weight 135.9 g (SD 47.9 g) were adapted themselves in the experimental water tank, 15 m Self-Governing 1.7 m in height and 1.5 m in depth, and then they were studied. We conducted experiment at the Ocean and Fisheries Research Institute in Jeju Special Self-Governing Province, from November to December 2015, and the sea surface temperature was between 16.5 and $19.5^{\circ}C$. The four colors of LED light, blue, white, green and red, were set up to transmit downward from the marginal area of tank. The 1 meter depth light intensity of LED colors is as follows: $0.09w/m^2/s$ (blue), $0.18w/m^2/s$ (white), $0.04w/m^2/s$ (green) and $0.007w/m^2/s$(red) To know the optimum LED color light, we selected one with better reaction rate after comparison of two colors simultaneously and the selected color was again compared to the other color in a tournament style two times a day (day and night) and ten times totally. The reaction rates were shown as the frequencies of hairtail appearance for 5 minutes in the lighting zone after turning on the LED lights. The reaction rate of the blue was at 97% unlike the red 3% (p < 0.001). The blue was at 75% unlike the green at 25% (p < 0.001). The blue was at 67% unlike the white at 33% (p < 0.001). Therefore, the color of light source showing the highest reaction rate was the blue.

  • Research literatures (e.g. research report, scientific paper and thesis, published between 2001 and 2005) of 332 collected from KISTI, KISS, ARPC databases were investigated and analyzed to give an overview of domestic ginseng researches. Most of recent ginseng researches have been performed by private nonprofit institutions and individuals, which suggests that a role of public institution fur ginseng researches needed to be enlarged. In terms of research fields, cultivation and agricultural researches have been mainly accomplished in ginseng research. Cell physiology and reproductive function researches occupied large part of pharmacological studies, but clinical studies were relatively limited. Studies on general food products development have taken the main part in fields of food products including functional foods. As the result of analysis of 312 domestic ginseng patents by classifications of world international property organization (WIPO), it was categorized into food technology, medicinal fermentation development technology, fermentation technology, and agriculture-fisheries technology. This integrated overview of the widely scattered ginseng literatures shows current general research trends in Korea and will be able to suggest further needs on cultivation, studies and industralization of ginseng.

  • The achievement emotion experienced by students in their academic settings is directly related with achievement activities or results. As the focuses of researches in the educational psychology have been extended to students' motives and emotion, the achievement emotion is also actively studied in Korea. The purpose of this study is to analyze researches on the achievement emotion according to social/cultural backgrounds by dividing them into domestic and foreign ones and understand flow and trend of the researches by structuring them. On the basis of the findings, it also aims to provide fundamental data necessary to examine the achievement emotion matched for academic settings in Korea. The objects of this study include a total of 105 domestic (n=47) and foreign (n=58) journal articles. The criteria of analysis are divided into period, contents and method of the study: the study was conducted without control of period; the contents include variables and achievement situations; and the method includes design and type of study, analysis methods, measurement tools and objects. The descriptive statistics of the materials were estimated by using the SPSS, and were analyzed by dividing them into domestic and foreign ones. The findings show that the researches on achievement emotion can be divided into examinations of the development of achievement emotion scale and those of the relationship between related variables. Thus, the conclusion suggests comprehensive discussions by arranging the trends of researches on the development of achievement emotion scale and the relationship between related variables.

  • The purpose of this study is to introduce an efficient measure in Korean language education for learners of Korean by applying shadowing techniques which focus on improving not only listening and speaking skills but also reading and writing skills. First of all, the study discusses about the definition of shadowing along with the effect of shadowing. The second part will be about examining the proposed method related to shadowing technique which is comprised of original shadowing techniques and other techniques transformed from the original. Thirdly, the paper will be discussing background information of the shadowing technique in previous researches and experiments using shadowing techniques in Korean language education. Finally, there will be an introduction of learning measures that apply to skill unification. Most of the previous researches of the shadowing technique were limited to a few students with only mid-to-high level learners while this method could cover up to a wide range of learners. The most effective way of learning a foreign language would firstly be the suggested method and the focus should be on repetition and practice of the learners.

  • This paper presents the status of advanced technologies and domestic researches for development of Korean next generation maglev. Generally, two specific configurations such as the EMS (Electromagnetic Suspension) with LSM (Linear Synchronous Motor) and EDS (Electrodynamic Suspension) with LSM can be employed as a propulsion and levitation device of high-speed maglev. Worldwide high-speed maglev developments refer to projects such as the German Transrapid with EMS, the Japanese MLX with EDS, and the U.S. Inductrack with PM (Permanent Magnet) EDS maglev system. In this paper, the propulsion and levitation systems of these world wide high-speed maglev have been reviewed and analysed.

  • The coast is important area to set up policies in aspects of environmental, international and developing of resources. The researches and surveying have been conducted by many different organizations according to their own purposes. So the fundamental researches and surveying of Korean coastal area haven't been completed. For that reason, we can't use the datum to apply for different cases. In this paper, Ive studied about our current situations and the need of surveying. For a effective research methods, we suggest dividing research areas into zones and dividing them into smaller zones, And we divide priority of research and ranging of surveying classes by grading them depending on the importance.

  • Simyak (審藥) was a government officer to lowest, but it was appointed and dispatched directly by officials from the central government. Simyak played a role in mediating between the provincial and central health care. Therefore, understanding Simyak is necessarily required in the researches on the local health care in Joseon dynasty. Preceding researches of Simyak only have contained superficial information causing many errors. The purpose of this paper is to understand Simyak correctly through the historical literature review. The author found the following facts in this study. First, Simyak was succeeded to the government officer of Uihakgyoyou (醫學敎諭) in the previous period. Second, through the change of the name of Simyak, it can be presumed that the main task of Simyak was changed from the role in local medical education to the officer sending the herbs to the central government. Third, in the later Joseon dynasty Simyak was monopolized by some families just like any other medical officials. Fourth, Yangdowollyengui (兩都月令醫) and Tongyeongguryogwan (統營救療官) can also be put in the category of Simyak.
