The perciform suborder Labroidei comprising six families (Cichlidae, Embiotocidae, Pomacentridae, Labridae, Odacidae, and Scaridae) are characterized by having the specialized pharyngeal jaws for food processing, i.e., united fifth ceratobranchials and upper pharyngeal jaw articulating with the basicranium via diarthroses (Stiassny and Jensen, 1987). They usually inhabit in the most tropical and subtropical seas and comprise about 235 genera and roughly 2,274 species worldwide (Nelson, 2006). Concerning the Korean labroid fishes, Mori (1952) had listed 18 genera and 26 species belong to four families in his check list of Korean fishes since Jordan and Metz (1913) firstly reported six genera and seven species in only two families (Embiotocidae and Labridae). Chyung (1977) added two species, Tilapia mossambica and Cirrhilabrus temmincki, to Mori’s list and also classified them into three suborders, i.e., Embiotocina (containing only Embiotocidae), Pomacentrina (Cichlidae and Pomacentridae), and Labrina (Labridae and Scaridae). Subsequently, Lee and Kim (1996) reviewed the Korean labroidfishes taxonomically resulting in 22 genera and 32 species in five families with some taxonomical modifications including a new Korean record. It is remarkable to be added many new Korean recordsto the pomacentrids or the labrids for recent 10 years (Koh et al., 1995; Yoo et al., 1995; Koh et al., 1997; Myoung, 1997; Choi and Kim, 2000; Choi et al., 2002; Kim and Go, 2003). Recently, Kim et al. (2005) briefly described all members of the Korean Labroidei with a color photograph or a figure, recognizing 27 genera and 42 species in five families. In the present study, the current taxonomical status of the Korean labroid fishes including distributional features is summarized based both on specimens collected from the Korean waters and on literature survey to provide bio-information of the Korean native fish species. As a result, the Korean labroid fishes totally consist of 27 genera and 44 species in five families, that is, Cichlidae (1 species), Embiotocidae (3), Pomacentridae (15), Labridae (22), and Scaridae (2). They distributed mainly in the coastal waters of the South Sea, Korea, however, most pomacentrids or labrids occur in the coastal waters of Jeju Island only, although some species were observed in their larval or juvenile stages only from coastal waters of the island. Interestingly, several species are expanding their distribution north to Ulreung and Dok islands in the East Sea, Korea lately.

This study proposed the design development of performance uniform for Korean classical music. To do this, we considered the state of the performance uniform of the Korean Classical Music Band through photographic data. The research targeted the performers in Korean Classical Music Band, and conducted a survey for the preference of type, pattern, decoration, color and fabric materials. Based on the results, we extracted the design of performance uniform, which is suitable for the environment of Korean classical music performance and meets the substantial requirements of performers. The performance uniform that the current national or public Korean classical music bands are using, has two types: Western clothing and Hanbok. The attire is influenced by the genre of the music that they are playing because one of its main functions is to deliver the music to audience effectively. In addition, there are some differences in the uniform based on the gender, but no division in the design of clothing according to music instruments. However, the result of the survey show that there was no difference in preference by gender, but there was some difference according to the division of music instruments. On this study, we reflected this result in the design, and proposed the design of an convenient outer garment for everyone to wear in the music performance band.

Survey was conducted through direct observation and interview for Electric Railway Power Team. A total of 352 copies were collected and analyzed. Based on the results of questionnaire, an experimental clothes, the functionality of which has improved in terms of design, material, and patterns, was created. The followings are the results of the study. Easy activity, design, and comfort are required as functions of working clothes. In design related questions, the survey shows high dissatisfaction in the color of existing working clothes, and preferred colors are dark blue and gray. With regard to the method of zipping up the front side, zippers are preferred. Although many pockets on the existing working clothes have high satisfaction, dissatisfaction to pocket format is high. In material related questions, lower dissatisfaction is indicated for the sense of touch, ventilation and sweat absorption. It is shown that the areas frequently polluted include the lower part of pocket, the edges of sleeves and elbow areas on the jacket. The frequently polluted area of the trousers include knee areas, the edges of pants and buttocks. With regard to the areas where the workers felt discomfort when motion, discomfort is highly indicated with armpits and back on the jacket. Also discomfort is highly indicated with crotch, buttocks and knee areas on the trousers. In material related questions, lower dissatisfaction is indicated for the sense of touch, ventilation, sweat absorption.

Woman leadership has been remarkably highlighted with women's accelerating entry into society. Domestic and overseas interests about political leaders began with the age of media and they are rapidly spreading worldwide with the development of internet, SNS and blog. Along with this phenomenon, exposure of images has been remarkably increasing and fashion has been also used as a political strategy. However, the research on woman political leaders has been insufficient so this study selected Geunhye Park, Michelle Obama and Hillary Clinton as representative woman leaders for the research. 149 pictures of Geunhye Park, 171 pictures of Michelle Obama and 124 pictures of Hillary Clinton from the articles containing their pictures from Jan. 2002 to Dec. 2013 were analyzed, focusing on their gender. The three woman political leaders' typical images of femininity, masculinity and androgyny were categorized respectively and the period and works in which those images had been expressed were reviewed. Also, fashion styles of the images pursued by each gender were analyzed through their color, material, silhouette, design point, items and accessories. As a result, Geunhye Park had femininity image at the beginning and had masculinity image when she did election campaigns, which led to her current image of androgyny. Michelle Obama uses the image of femininity, masculinity and androgyny simultaneously. It was found that Hillary Clinton emphasized the image of masculinity and androgyny but she emphasizes femininity image these days.

Lycopene is the red-coloured carotenoid predominantly found in tomato fruit and one of the major carotenoids in the diets of North American and Europeans. Interest in lycopene is growing rapidly following the recent publication of its effects as a natural antioxidant and prevention of cardiovascular disease and cancers. Lycopene, a polyene hydrocarbon carotenoid haying 13 double bond, of which 11 are conjugated double bonds in a linear array exhibits a strong antioxidant property almost twice as strong as that of ${\beta}$-carotene. Lycopene has been shown in recent epidemiological and experimental studies to protect against oxidative damage of DNA which plays an important part in development of various cancer. Lycopene also contribute towards reducing the risk of cardiovascular diseases by preventing oxidation of low-density lipoprotein(LDL) cholesterol. This review summarize our knowledge and the current understanding of lycopene in human health as well as the results of experiments we conducted. We conducted experiments for investigating the effects of antioxidant in broiler and the possibilities of production of high quality eggs containing lycopene by the dietary lycopene supplementation with synthetic lycopene or tomato paste. The results shows that thiobarbituric acid reaction substances(TBARS) values in process of LDL oxidation in blood serum of broiler were significantly decreased by dietary lycopene and tomato paste. The dietary lycopene supplementation resulted in improved egg yolk color and in decreased the malondialdehyde (MDA) of egg yolk after 4 wk of storage at room temperature significantly(P<0.05). The dietary tomato paste was more effective in the MDA reduction compared to the lycopene(P<0.05). The contents of lycopene in egg yolk of the lycopene supplementation groups were significantly higher than those of the control group.

The reduction mechanism at a mercury electrode of o-cresolphthalexon(OCP) in strongly alkaline supporting electrolytes has been investigated by several electrochemical techniques. The radical formed after first one electron reduction uptake, dimerizes. The result of cyclic voltammetric investigation demonstrated the reversible nature of the electron transfer and standard rate constant was $3.27{\times}10^{-2}$ cm/sec. The apparent irreversible behavior of the second wave is a result of the existence of a fast protonation following the second electron transfer. At low concentration of OCP(< $1{\times}10^{-4}$M), cathodic current were remarkably adsorptive properties. Prolonged electrolysis was carried out at controlled potential of -1.85V, original violet color of the solution becames progressively weaker, and then colorless solution. The final product of an exhaustive electrolysis is electro-inactive. The appearence of four steps may be explained by the fact that the reduction of OCP elucidated ECEC mechanism.

One of the research objectives in the area of multimedia human-computer interaction is the application of artificial intelligence and robotics technologies to the development of computer interfaces. This involves utilizing many forms of media, integrating speed input, natural language, graphics, hand pointing gestures, and other methods for interactive dialogues. Although current human-computer communication methods include computer keyboards, mice, and other traditional devices, the two basic ways by which people communicate with each other are voice and gesture. This paper reports on research focusing on the development of an intelligent multimedia interface system modeled based on the manner in which people communicate. This work explores the interaction between humans and computers based only on the processing of speech(Work uttered by the person) and processing of images(hand pointing gestures). The purpose of the interface is to control a pan/tilt camera to point it to a location specified by the user through utterance of words and pointing of the hand, The systems utilizes another stationary camera to capture images of the users hand and a microphone to capture the users words. Upon processing of the images and sounds, the systems responds by pointing the camera. Initially, the interface uses hand pointing to locate the general position which user is referring to and then the interface uses voice command provided by user to fine-the location, and change the zooming of the camera, if requested. The image of the location is captured by the pan/tilt camera and sent to a color TV monitor to be displayed. This type of system has applications in tele-conferencing and other rmote operations, where the system must respond to users command, in a manner similar to how the user would communicate with another person. The advantage of this approach is the elimination of the traditional input devices that the user must utilize in order to control a pan/tillt camera, replacing them with more "natural" means of interaction. A number of experiments were performed to evaluate the interface system with respect to its accuracy, efficiency, reliability, and limitation.

In our general life, what we recognize information with our human eyes and use it is diverse and massive. But even the current technologies improved by artificial intelligence are exorbitantly deficient comparing to human visual processing ability. Nevertheless, many researchers are trying to get information in everyday life, especially concentrate effort on recognizing information consisted of text. In the fields of recognizing text, to extract the text from the general document is used in some information processing fields, but to extract and recognize the text from real image is deficient too much yet. It is because the real images have many properties like color, size, orientation and something in common. In this paper, we applies an adaptive edge enhanced MSER(Maximally Stable Extremal Regions) to extract the text area in those diverse environments and the scene text, and show that the proposed method is a comparatively nice method with experiments.

Objective: The present study identified the minimum legible text size by an experiment for eight combinations of background and text colors, which will be used in designing visual information on group-view display (GVD). Background: Information on minimum legible text size is needed to design the visual information presented on GVD in a radioactive waste control room. Method: The experiment was conducted for 22 male participants (age: mean = 37, SD = 6.7; visual acuity: over 0.8) who were recruited by considering demographic characteristics of current control room operators. Eight combinations of background and text colors were considered and the minimum legible text size was determined for each combination by applying the method of limits, one of psychophysical methods. Results: The minimum legible text size was significantly different in accordance with the combination of background and text colors. Statistical analysis results showed that luminance contrast and color contrast between background and text influenced the minimum legible text sizes. Conclusion: This study concluded that the minimum legible text size is 8 minute of arc for various combinations of background and text colors. Application: The minimum legible text size identified in the present study can be utilized in designing visual information on GVD at the main control room in a radioactive waste facility.
