This study analyzed the types of scientific humors made by scientifically-gifted elementary school students and their perceptions of making scientific humor. For this, 77 students from $4^{th}$ to $6^{th}$ graders of gifted science education center in Seoul National University of Education were selected. Scientific humors made by the students were analyzed according to the number and types. Their perceptions of making scientific humor were also analyzed through a questionnaire and group interviews. The analysis of the results revealed that most of scientifically-gifted students made more than 2 scientific humors, and the number of scientific humor for each students varied from 0 to 11. The most types they made were the descriptive type and the pun using pronunciation type, but they made various types without any special type to be biased. And They made more the dialogue type than the narrative type, especially the riddle type. They used scientific knowledge that preceded the knowledge of science curriculum in their grade level over two or more years. The scientific knowledge of chemistry was used more than physics, biology, earth science and combination field. The name utilization type was more than the characteristic utilization type and the principle utilization type. Scientific humors in the everyday situation were more than humors in artificial situation. The students had various positive perceptions in making scientific humor such as increase of scientific knowledge, increase of various thinking abilities, deep understanding of science concept and principle, increase of interest and motivation about science and science learning, and increase on sense of humor. They had also some negative perceptions related to difficulties in the process of making scientific humor, lack of fun, and lack of time in the class.

This paper is an observation on the woman's warming hoods such as Nambawi, Pungchae, Ahyam, Jnbawi and Gullae worn form 1800's through 1930's. At the late era of Chosun dynasty, The every day lifes of people were greatly influenced by invasion of western world, in particular the styles of clothing are changed from original one to Western-like. So the hoods of our own's were dissappcared gradually, and the interests of them were reduced accordingly by the western culture invaded. Therefore this paper is intended to participate in the study of clothing culture by considering of hoods, one of the almost disappeared clothes, and review the wisdom and sense of beauty of our ancestor by unique ornament. The warming hoods in this paper are from a category of ear-protection gear and also deformed from man's one. The ear-protection gear was a warming hood from Tae Jong, the king of the early era of Chosun, and usage classifications of them were strict according to the class division at the early and mid era of Chosun, but generally diminised at the late era, thery were used freely, but the differences in decorations represented the division of the rich and poor. General feature of it is open top, but covers all of head and is used for warming clothes, with has many decorations on it, this decorative tendency was more clear at the late era. Namely, the shape had been modified from tough one to modish one, and fur, the material of it, are from stiff and long to soft short and well refined. This warming hoods were used until 1930's then disappeared by the population of western mufflers and wraps. Jobawi is now already forgotten even its name except for the ornament in picturing the baby in first birth day. In revewing the consideration of warming hoods mentioned. It is found that the subtlety of the ancestor, and there are supplication for the happiness of life even in the decorations.

This research is a follow-up study of the analysis of satisfaction and preference rates in bathroom design relevant to age variable. This project examines the satisfaction and preference rates relevant to the variety a family type. Mid-sized apartments most favored by the mid-class families were selected as the objects of the research so that they represent the present conditions in Korean bathroom designs most comprehensively. In order to maintain consistency in research objects, this article limited them to the top five brand-name apartments in the metropolitan area based on the brand popularity and construction capability. The method of the research was surveys; we were able to retrieve and analyze 427 copies through internet. The data were processed by SPSS PC+ windows version 15.0 program and were analyzed using the means, crosstabs statistics, One-way ANOVA. The results are as follows: 1) The most significant factor that determines the variety a family type is the existence of senior citizens in the household. 2) The preference of families with young children is mostly determined by elements related to the safety of the children. 3) The satisfaction and preference rates are closely related to family types of each household. We sincerely hope that this article will provide guidelines for customized bathroom designs based on the ages, life cycles, and socioeconomic status of the residents so that the desings will answer to the needs of each household.

Dipeptidyl peptidase4 (DPP4) inhibitors such as gemigliptin are antidiabetic drugs elevating plasma concentration of incretins such as GLP-1. In addition to the DPP4 inhibition, gemigliptin might directly improve the functions of vessels under pathological conditions. To test this hypothesis, we investigated whether the acetylcholine-induced endothelium dependent relaxation (ACh-EDR) of mesenteric arteries (MA) are altered by gemigliptin pretreatment in Spontaneous Hypertensive Rats (SHR) and in Wistar-Kyoto rats (WKY) under hyperglycemia-like conditions (HG; 2 hr incubation with 50 mM glucose). ACh-EDR of WKY was reduced by the HG condition, which was significantly recovered by $1{\mu}M$ gemigliptin while not by saxagliptin and sitagliptin up to $10{\mu}M$. The ACh-EDR of SHR MA was also improved by $1{\mu}M$ gemigliptin while similar recovery was observed with higher concentration ($10{\mu}M$) of saxagliptin and sitagliptin. The facilitation of ACh-EDR by gemigliptin in SHR was not observed under pretreatment with NOS inhibitor, L-NAME. In the endothelium-denuded MA of SHR, sodium nitroprusside induced dose-dependent relaxation was not affected by gemigliptin. The ACh-EDR in WKY was decreased by treatment with $30{\mu}M$ pyrogallol, a superoxide generator, which was not prevented by gemigliptin. Exendin-4, a GLP-1 analogue, could not enhance the ACh-EDR in SHR MA. The present results of ex vivo study suggest that gemigliptin enhances the NOS-mediated EDR of the HG-treated MA as well as the MA from SHR via GLP-1 receptor independent mechanism.

Ginseng is a popular medicinal plant highly valued throughout the world. Asian ginseng is one of the most common species of ginseng. It has long occupied a significant position in oriental medicine and has been justified its name as the 'king herb'. As a nutritional supplement, ginseng is an extremely common and popular herbal medicine in the United States and Canada in recent decades. The multiple constituents of ginseng possess equally multifaceted pharmacological actions as demonstrated by numerous studies. Ginseng root and its constituents influenced the central nervous system, endocrine, cardiovascular, gastrointestinal system, sexual, renal organ and immune system, etc. One important action is its anti-hyperglycemic effect. Previous studies on ginseng demonstrate that only the root of ginseng has been used in the treatment of diabetes, while the other parts of ginseng plant were always neglected. Recently, we analyzed the constituents of ginseng berry, leaf and discovered that ginseng berry, leaf extracts and its total ginsenosides have the ability to reduce hyperglycemia and body weight and increase the peripheral glucose utilization in obese or diabetic ob/ob or db/db mice. Our data suggest that all parts of ginseng plant, including root, berry, leaf and stem exhibit potent anti-hyperglycemic and anti-obese effects and may provide an opportunity to develop a novel class of anti-diabetic agents.

The modern cartilaginous fishes, class Chondrichthyes, are small group of Pisces, and comprisingmore 1,000 described valid species, and including approximately 190 genera, 55 families, and 15 orders. The Chondrichthyes consists of two subclasses, the Holocephali (chimeras) and the Elasmobranchii(sharks and rays). The dominant subclass Elasmobranchii includes sharks (Selachii) and rays (Batoidea), the former is more diverse than the latter in higher taxa (order, family, genus) but has fewer species. The Batoidea, batoids or rays, has long been recognized as monophyletic, however, the interrelationships of the groups are problematic and uncertain. In order to review biodiversity and systematics of batoids, valid species name and supraspecific taxa from the published materials are studied. Batoids (including sawfishes, Pristiformes; electric rays, Torpediniformes; stingrays, Myliobatiformes; skates, Rajiformes; wedgefishes, Rhiniformes; and guitarfishes, Rhinobatiformes) is speciose and worldwide with about 580 species in 4 to 6 orders, 17 to 19 families, and about 75 genera. In East Asian waters, the previous records of the Batoidea reveal about 170 species belonging to 41 genera, 18 families, 6 orders. The largest group of batoid fauna in the area is order Myliobatiformes comprising about 80 species, 16 genera of 7 families. The predominant families are Dasyatidae (whiptail stingrays: 46 spp. of 6 genera), Arhynchobatidae (softnose skates: 26 spp. of 3 genera), and Rajidae (skates: 21 spp. of 6 genera). The predominant genera are Bathyraja (softnoseskates: 20 spp.), Himantura (whiprays:19spp.), and Dasyatis (fantailstingrays: 18 spp.). There are 23 species in the Yellow Sea, 70 species in the East China Sea, 82 species in the South China Sea, and 58 species in the North Pacific coast of Japan. Batoid fauna from the East Sea (Sea of Japan) is the poorest of the five regions, consisting of 14 species. Korean waters include only 28 species, 16 genera, 10 families and 5 orders of batoids. Two species is torpediniforms, 4 rhinobatiforms, arhynchobatiforms, 11 rajiforms and 10 myliobatiforms. By the earlier works, the systematics and a check list of the valid species of batoids will be presented.

The Traditional Look, a class of fashion, represents image based on British aristocratic authenticity and cultural heritage as unchangeable and lasting classic fashion style. And recently, it keeps up with the trend of modern and young consumers' desire by putting various images. The purpose of the study is to investigate the concept, image and present market condition and to analyze degree of consumers' brand awareness of Traditional brand in pursuit of developing new market and ensuring power between competitive brands. From above work, surveyed on degree of brand awareness and interest, preference, associable image and purchase factors coming from consumers. 606 data were analyzed with SPSS package. Frequency, Factor analysis, one-way ANOVA, Multiple response, and correlation were applied. The results of this study were as follows. 1. Traditional brand has a high degree at consumers' brand awareness but comparatively lower at interest in it. In band name, while the Burberry has the highest brand awareness, the Polo and the Hunt take first and second position in a purchasing rate. Brand preference has tendency to be concentrated on certain brands showing the outstanding highest degree like the Polo in the 20s, and the Burberry in the 50s in aspect of age structure. 2. In associable image of Traditional brand, it is associate with noble image as dignified, classical and intellectual with itself strongly among practical, individuality, confidential and noble image. 3. As the purchase factors of traditional brand products, it depends on mainly the reliability and esthetic factors like design and quality rather than ostentatious and practical factors. 4. Associable image except individuality image is correlated with the purchase factors of traditional brand.

Basic concept of this study is that architectural form as a material at present has meaning for the dweller's life on the past historical plane. Main method to recover history is ethnographic interview to dwellers. Secondary method is to analyze ancestors' writings, buildings in the background of the family photos, and past drawings and then to relate them with architectural form at present. Taxonomy is a starting point: general name of the building by outside researcher is quite different from it by inside dwellers. 'Haengrang-chae', servant quarter, has never been used for servants. Function of the haengrang went outside thatched houses at the front village. Firsthand observation or simple analyses as results of several precedent research are reexamined and criticized through this study. The mansion has moaning when we synthesize with the site location based on farming land and tenant farmer, and decline of the Kyongpo Lake. Territoriality of the mansion is reinterpreted to 'In-Out Structure' by Yin-Yang thinking, Dwellers extend buildings gradually to outside village, surrounding rear hills, the lake, DongHae Sea, and finally goes to imaginative Taoist heaven beyond real nature through the literary life. Confucius principle, known to govern upper class house at Yi Dynasty also affect general composition of the buildings: perpetuation of the family by ancestor worship, elder dominance and male dominance, fraternity love in the extended family, charity display by reception of guests, Taoist scholarly life harmonized with nature. However, the study of the particular life and usage of the dwellers reinforces or corrects general supposition of precedent researches. Unique shape of the house has been formed by convenience of the dwellers' life style, early modernized free thought over the rigid Confucius design principle, and female power in male dominant society.

The Korean animation has enjoyed the brisk formation and establishment of its world-class infra for the last several years without unified titles or concepts, under the name of a national strategic project in the age of digital image. It also enjoys its new evaluation as digital animation that it's one of the greatest money making business in the non-education and frivolous culture and has the closest relations with the modern time. A great portion of popular image media has been taken by animation for the last 30 years. In this paper we propose a motion algorithm using an animation technology. It was developed for education purposed and accessible through the internet. For instance, in Cyber Clam Museum, 1000 gesture contents, the visual processes were used to design a screen with a realistic image and create an animation that makes possible show at 360 and every such transformation as translation, rotation, and scaling can be applied in the image interactively for the convenient and effective viewing.
