The study focuses on the morphology of larval and juvenile codlets, Bregmaceros atlanticus, collected from the East China Sea in May 2001 and September 2002. A total of 47 individuals were collected by using an IKMT, and the range of their body lengths was $2.41{\sim}17.18$ mm. Specimens can be categorized into two groups: larvae and juvenile. The first group, in which the yolk is completely absorbed, had a body length of 2.41m. They had big heads, and large and thick melanophores were sparsely scattered about the head, bottom of the pectoral fins, rear parts of the trunk and ends of the notochords. The specimens had a body length of 2.54mm and over, and thin and elongated body trunks. Their heads were significantly smaller, including the body depth, and melanophores were coarsely developed all over their bodies. Occipital rays, the first and unique-ray dorsal fin, were observed on individuals of body length greater than 4.01 m, and the rays grew proportionally with body length, but didn't reach the root of the second dorsal fin. The second group, juveniles, had an body length of 9.82mm and over, and their fin rays satisfied the completed numbers of rays and vertebrae for adults. Melanophores were densely scattered all over the body, where thick colors were observed on the rear parts of the dorsal and anal fins and front part of the caudal fin.

The purpose of this study was to investigate the change of clothes in modem Korean women in terms of a socioeconomical background, the introduction to western clothes, and the improvement of clothes between the opening period of ports in the early 1900's and 1960's. In addition, the study investigated how western clothes became popular in a Korean society along with the traditional' Korean clothes, Hanbok. The radical social change since the opening of ports motivated the change in the way of Korean women's thinking, and consequenty the improvement of Hanbok which developed into the clothes-improvement-movement. It was not until 1905 that the improvement of clothes was hotly debated particularly in the matter of abolishing Jangeui and the extreme length of Jeogori and Chima. The Tongchima-Jeogori style which lengthened Jeogori and shortened Chima was widely accepted as everyday wear until the western clothes substituted them after the Independence from Japanese Conquest. As the length of Chima shortened, there occurred a change in Boson and Jipsin as well. There appeared shoes and Gomoosin in place of Jipsin, socks in stead of Boson and were popularized until after the Liberation in 1945. The popularity of Gomoosin diminished markedly with the diversification of shoes styles, due to the improvement of the standard of living with economic development in the 1960's. The traditional Hanbok was gradually differentiated according to the social status, for instance student, teachers, ordinary women, girls and Kisaeng. Especially since the white clothes caused much trouble in washing and sewing, there came into being the movement of wearing colorful clothes. The Movement of abolishing white clothes and promoting of wearing colorful clothes was enforced during the period of Japaness conquest from the 1920's to the Liberation, which consequently stimulated an interest for colors of clothes. The period under the war between 1937 and 1945 was especially noted for the extreme regulation over the clothes. The Japanese government forced each group of women, e.g., girl students, a young women's association, school teachers, and ordinary women and girls, to wear their own uniforms. Also, It recommended the use of Tongchima in stead of long skirts, and buttons in place of Coreum so as to conserve textile encouraging the use of other substitutes to save resources. The western clothes, a model of clothe's improvement was deemed as a symbol of modernization and enjoyed general popularity. The supply of relief clothes after the Korean war accelerated the expansion of western clothes even further and the trend of westernization along with economic progress in the 1960's resulted in wearing of western clothes as everyday dress. The expansion of western clothes as casual wear rapidly diminished wearing of Hanbok which in turn took the position of ceremonial dress worn in special cases only. Hence the Korean women's clothes were dualized into traditional Hanbok and western clothes and the western clothes that stems on its convenience was settled as everyday wear where as the Hanbok appeared as ceremonial dress stressing on ornamental features. As mentioned aboved, we are able to discovered an orientation in the course of transitional process of modern Korean women's clothes admist diversified changes, which is a consistent pursuit of convenience and practicality based upon progmatism. The trend such as this carne into a finale' as women's dress became dualistic in forms of Hanbok and western clothes, and the change since then is supposed to proceed in two forms of dress featuring its own style.

Marek(말액) is the headgear, which is a form of hempen hoods[Geon(건)] and the origin of it is Pa(파) of band form. A history book of an old Chinese country Post-Han $\ll$ History of HouHan (후한서)$\gg$ had recorded that a soldier wore a red band around his head that was called Pa(파). In the Han dynasty(한대), Pa had been transformed into Chaek(책) or a kind of a hemp rap(건) while e headgear had still remained as the band form and called Marek from e Tang era(당). The literatures of the Tang era had referred the red Marek of soldiers, and other literatures of the later period had recorded that of the previous headgears of the band form were related with Marek. Since the Tang era, white or yellow Marek except red one fer soldiers had been were by soldiers, musicians, dancers and singers in Yuan(원) and Ming(명) of China. The colors was recorded in red on documents mostly, this red implicated soldiers for symbol of terror. This fart was documented in an old history book $\ll$The history of 25 Eras(이십오사)$\gg$, On the other side, a wall painting in Princess Jeonghyo(정효공주)'s tomb of the Parhae(발해) period described the portraits of twelve persons, and among them, two Siwui(시위) put on the red Marek. Quoted from the record of a history book of the Tang era system , a history book of Three Kingdoms(삼국시대) of ancient Korea $\ll$Samguksaki(삼국사기)$\gg$ described that four dancers of Kogryo(고구려) wore Marek on their heads with the costumes of Koguryo, one of those Kingdoms. In consideration that the book of $\ll$Tongjun$\gg$ was the literature of the Tang era so that Marek mentioned in this book was followed by their name, the Marek of Koguryo dancers shown in the history book $\ll$Samguksaki(삼국사기)$\gg$ might be a kind of Koguryo style hemp cap[Geon(건)]. The Marek of Parhae had succeeded to the headgear of Koguryo and the identity was on Koguryo.

The purpose of this study was to explore the stressors in pediatric intensive care unit and impaired psychological responses of children after open heart surgery. Sixteen children aged 6 to 11, who were admitted to the hospital for open heart surgery during the period from July, 1991 to February, 1992 were the subjects of the study. Observations, drawings, and interviews were used to collect data for study. Behavioral responses about intensive care unit phenomena were analyzed according to the 4 categories identified to assess children's perceived stressors in ICU. Impaired psychological responses were examined using observational and interview data. Drawings were analyzed by content and color by this researcher and validated by the psychologist. The findings were as follows : 1. The most frequently perceived stressors by children in ICU were the physical stressors causing pain and discomfort(68.5%). It was followed by social stressors which denote disruption of relationship with family and friends(13.0% ), environmental stressors which denote unfamiliar surroundings, noise, staff, and other patients (11.2%), and psychological stressors which denote factors affecting self-esteem such as inability to communicate and inadquate knowledge of the situation (7.3%). 2. 81.3% of the children showed of least one of the impaired psychological responses. Three children (18.8%) experienced time disorientation. An equal number of subject experienced perceptual illusion. Two children(12.5%) experienced hallucination. Vivid dream about ICU phenomena was reported by 2 children. Seven children(43.8%) were identified as having exaggerated fear. They feared about oxygen mask and ICU environment in general. Seven children(43.8%) experienced impairment of memory about treatments, procedures, and environment of ICU. 3. The analysis of children's drawing revealed that 56.3% of children experienced fear in the ICU. 75% of children included nurses in the drawings and 62.5% of children drew other children. 81.3% of children drew and identified himself in the drawing. The colors used most by children were green, purple, and brown. From this result, it is recommended to prepare children before open heart surgery to reduce their stressors and impaired psychological responses in ICU.

This study is an exploratory study on the package design research strategy for the activation of the energy drink market. We analyzed the case study of energy drinks and the preference of energy beverage package design which are being sold in Korea and overseas from Oct. 24 to 28, 2016. The results of this study are as follows: First, preference is given to two colors, blue and red, regarding the color of package design of energy drinks. In particular, blue was the most preferred at 62.8%, and the reason for choosing color was the image that reminds me of energy drinks, and it was highly visible. Second, most preference of energy drinks for packaging material was selected from can and glass materials, and most preferred for can. Third, preference for calligraphy was found to be due to the dynamic images of energy drink preferring rough images. Fourth, package design awareness focused on overall image rather than one factor. The limitations of the study are the research subjects only to university students in Daejeon and Chungnam area. In the future, it will be necessary to classify the overall elements of package design and various research subjects, and to study the major consumption and consumption areas of energy drinks. In this study, it is implied that the design of the package needs a package design strategy in accordance with the overall product image, rather than focusing on one factor.

In this paper, we propose VLC(visible light communication) based multi-hop multimedia data transmission system. The main contributions and features of the proposed system are as follows. First, the contribution of this research is to develope the LED communication based multi-hop transmission network system which can transmit multimedia data(audio data, video data) with long distance. Second, the developed system has the following features: In transmitter, audio data and video data are transmitted via multi-hops using two channels. The relay in audio channel receives digital audio signal by using photo diode and then transmits the signal to receiver after error checking and amplifying. The receiver receives the encoded audio data via photo diode and then converts to analog audio signal by using decoding and amplifying. The relay in video channel receives video signal by using photo diode and then amplify the video signal using OP-AMP and then transmits the signal to receiver. The receiver amplifies the received signal from photo diode and then sends it to the monitor. The performance evaluation of the proposed system is conducted in the laboratory with fluorescent light source. The results of the performance evaluation confirm that the system can provide high quality multimedia data transmission from transmiter to receiver via multi-hop relays in a long distance while we can see there are differences in the transmitted multimedia(audio and video) quality according to the used LED colors.

A new content-based color image retrieval method integrating the features of the color adjacency and the gradient is proposed in this paper. As the most used feature of color image, color histogram has its own advantages that it is invariant to the changes in viewpoint and the rotation of the image etc., and the computation of the feature is simple and fast. However, it is difficult to distinguish those different images having similar color distributions using histogram-based image retrieval, because the color histogram is generated on uniformly quantized colors and the histogram itself contains no spatial information. And another shortcoming of the histogram-based image retrieval is the storage of the features is usually very large. In order to prevent the above drawbacks, the gradient that is the largest color difference of neighboring pixels is calculated in the proposed method instead of the uniform quantization which is commonly used at most histogram-based methods. And the color adjacency information which indicates major color composition feature of an image is extracted and represented as a binary form to reduce the amount of feature storage. The two features are integrated to allow the retrieval more robust to the changes of various external conditions.

Currently many devices reproduce electronic images in the various ways. However, the color that is reproduced in any device is different from the original color due to the differences in the gamut between devices. A recent trend in gamut mapping algorithms is the use of spatial information to compute the color transformation of pixels from the input to the output gamut. However, these techniques share the problem of preserving details, and avoiding halos, and hue shift. In this paper, spatial gamut mapping for preserving the details of the input image is proposed. Our approach improves visibility of detail that is not effectively represented with conventional spatial gamut mapping. In proposed method, initially, we gamut map the input image using gamut clipping and obtain a detail layer for both the input and the gamut mapped images. Next, we calculate the difference between the two detail layers, obtaining the details of the out of gamut region. Finally, we add the details of out of gamut region to the gamut mapped image. Since the resulting image has out of gamut colors, we obtain resulting image of proposed method by using a gamut clipping method. Consequently, the printed output image was more consistent with the corresponding monitor image.

This study investigates the dominant degree of product design factors through the process of change of design factors. The previous research suggested a concrete measurement method of dominant designs, but it did not investigate empirically the degree of dominance due to the limited data for changes of designs. In this research, thus, after collecting design data of mobile phones and we measured the dominance and structure change of the designs by year. The analyses showed the following two things. First, in design factors of mobile phone the dominance on the body form and the edge grows more and both of them as dominant design factors tend to converge into the rectangular body form and the round edge, respectively. Second, the dominance on other design factors(e.g. the button type, the open type, whether or not to have digital multimedia broadcasting(DMB) and video telephony functions, the combination of colors and the body color) increases and decreases; and hence, design levels tend to diverge. In conclusion, the measurement of dominance on product design factors contributes to marketing managers and designers who are required to establish a strategy for products under the rapidly changing circumstances of market. This research aims to provide those managers and designers with a guide line for a successful development of new product to prepare for the dominant design from this empirical study.

Two experiments were conducted to investigate the dietary effects of conventional or lutein fortified chlorella on lutein absorptions, the tissue distributions and the changes in lutein content of eggs in laying hens. In Exp 1, a total of one hundred and fifty, 70 wk-old Hy-Line brown layers were divided into three groups with five replicates and fed with each experiment diet (control diet, diet with 1% conventional chlorella or lutein fortified chlorella) for 2 wk, respectively. The egg production in groups fed diets containing both chlorella powders were higher than that of the control group (p<0.01). With chlorella supplementations, the yolk color significantly increased, although there were no significant differences in the eggshell qualities. The lutein contents of serum, liver and growing oocytes were greatly increased by feeding conventional or lutein fortified chlorella (p<0.01). In Exp. 2, a total of ninety 60 wk-old Hy-Line brown layers were assigned into three groups with three replicates per group (10 birds per replicate). The birds were fed with one of three experimental diets (0, 0.1 or 0.2% lutein fortified chlorella) for 2 wk, respectively. The egg production was not affected by dietary treatments. The egg weight in the group fed with diet containing 0.2% of lutein fortified chlorella was higher than that of the control (p<0.05). As the dietary chlorella levels increased, the daily egg mass linearly increased, although not significantly. The yolk colors in groups fed diets containing lutein fortified chlorella were dramatically increased as compared to the control (p<0.001). The lutein in chicken eggs significantly increased when fed with 0.2% of lutein fortified chlorella (p<0.01). These results suggested that the dietary lutein derived from chlorella was readily absorbed into the serum and absorbed by the liver with growing oocyte for commercial laying hens. Particularly, the lutein fortified chlorella was a valuable natural source for the production of lutein enriched chicken eggs.
