A new species belonging to the genus Cyclopinoides Lindberg, 1953 (Cyclopinidae) is described from three beaches in Korea and Japan, as the first record of the genus from the Pacific. Among five species currently recognized in the genus, the new species resembles C. schulzi Herbst, 1964 from the Red Sea in sharing the character combination of 20-segmented antennule and stumpy caudal rami. However, C. orientalis n. sp. differs from it by relatively longer caudal rami (2.5-2.8 times as long as wide in female and about 1.6-1.8 times in male, while less than 2 times in female and about 1.3 times in male of C. schulzi), and by the transformation of an outer distal spine to a slender seta on the distal exopodal segment of leg 4. Moreover, C. orientalis n. sp. is discernible from C. schulzi in having a pyriform copulatory tube (against elongated tubular style in C. schulzi). A key to the species hitherto known in the genus is provided.

Morphological changes of flowers and insect visitors were observed to investigate pollinator of Caesalpinia decapetala. The flowers of C. decapetala are protandrous. Functionally, the flower is changed from male to female. As a male, pollen grain is released after anther dehisced while style is immature. After completed pollen grain release, the style starts to lengthen. It helps the stigma to easily touch the carpenter bee's thorax covered with pollen grain. At this time, flower functions as a female. The majority of taxa and individuals observed were Hymenoptera. The most frequent visitor was the Xylocopa appendiculata circumvolans, carpenter bee. Carpenter bees exhibited only typical pollinator behavior among flower visitors, with touching reproductive organs and seeking nectar at the same time. The pollination behavior is as follows. Soon after carpenter bees perceived guide mark, they foraged rightward and grasped style and stamens with legs and they inserted proboscis into standard petal to seek nectar. With this behavior, the pollen grains of the male flower transfer to the ventral thorax of the carpenter bee. As the carpenter bee moves to another female flower, the deposited pollen grains are delivered to the stigma.

혈관내피세포 기능장애는 동맥경화증 발생의 초기단계이다. 비타민B군(B6, B12, 엽산)은 혈관항상성에 중요한 인자이다. 이들 비타민B군이 결핍되면 혈관항상성에 변화가 생겨 심혈관질환을 유발한다. 비타민B군 중 엽산은 내피세포에서 산화질소 항상성에 중요한 역할을 한다. 동맥경화증에 관련된 섭취엽산의 용량의존적 효과를 알기 위해, C57BL/6 쥐의 대동맥이완과 간 C반응단백질 수준을 연구하였다. 본 연구는 총 54마리의 C57BL/6 쥐를 서양식이군과 대조식이군으로 나누고, 각각은 다시 엽산섭취용량(0.2, 2, 8mg/kg)에 따라 3형태의 하위집단으로 나누었다. 18개월 동안의 식이섭취후, 양군의 8mg/kg 엽산섭취용량에서는 대동맥 이완반응을 전혀 나타내지 않았고 양군의 차이도 없었다(p<0.05). 모든 엽산섭취용량(0.2, 2, 8mg/kg)에서 간 C반응단백질 수준은 대조식이군보다 서양식이군에서 더 높았다(p=0.035). 양군의 간 C반응단백질 수준은 0.2 mg/kg 엽산섭취용량에서 가장 낮았다(p<0.05). 결론적으로, C57BL/6 쥐에서 식이에 관계없이 0.2 mg/kg 엽산섭취용량만으로도 대동맥의 이완반응을 유도하고 간 C반응단백질 수준을 낮춤으로써 동맥경화증을 충분히 예방할 수 있다.

This study was undertaken to investigate the relationship between the life style and the nutritional status of serum antioxidant vitamins and lipids in university male and female students. 48 male and 49 female students attending Andong university, aged between 18 and 25 years, were selected. Questions about the life styles including dietary intakes, food habits, smoking, drinking alcohol, exercise, stress were answered. And serum levels of antioxidant vitamins and lipids were determined. Average serum levels of total cholesterol, LDL C, HDL C, and triglyceride in male and female subjects were 158.6$\pm$32.7, 177.3$\pm$33.8; 86.4$\pm$26.0, 109.0$\pm$31.2; 46.0$\pm$10.7, 49.9$\pm$12.4; 131.2$\pm$22.5, 91.7$\pm$ 38.6mg/dl respectively. Average serum levels of antioxidant vitamin A, E and C in male and female subjects were 42.6$\pm$12.3, 31.4$\pm$9.8 g/dl, 1.11$\pm$0.38, 1.15$\pm$0.29mg/dl and 164.66 $\pm$65.01, 220.06$\pm$80.11 g/dl respectively. There was no significant difference between smoking habits and either serum lipids or antioxidant vitamins level. The serum vitamin C level of drinkers was significantly lower(p=0.038), but serum lipids(total cholesterol, LDL C, and triglyceride) were higher than non alcoholic subjects. The subjects with severe stress had lower in HDL C and higher in atherogenic index than others. This result indicates that oxidative stress may be increased in stressful environment from undesirable life styles and influence the status of serum lipid and antioxidant vitamins.

Purpose: The purpose of this study was to identify predictors of obesity, serum lipids and CRP in Korean adults. The predictors of obesity and serum lipids were the subject's general characteristics, life style, eating habit and nutrients. The predictors of CRP were the subject's general characteristics, life style, eating habit, nutrients, obesity and serum lipids. Method: 115 subjects who had visited the health examination center at a hospital participated in the study. The data analysed with descriptive analysis, ANOVA, Chi-square test, Pearson correlation coefficient and multiple regression. Result: Sex, married, eating out ($4{\leq}$/w), eating out (2-3/w) and age ($61{\leq}$) were anticipated variable on BMI ($R^2$=0.488). Sex and overeating (2-3/w) were anticipated variable on body fat($R^2$=0.218). Drink (4-6/w), age (51-60), sex, vegetable fat and Systolic BP were anticipated variable on total cholesterol ($R^2$=0.217). Age (51-60), vegetable fat and unmarried were anticipated variable on LDL ($R^2$=0.180). Sex was anticipated variable on HDL and Triglyceride ($R^2$=0.054, 0.192). Breakfast (1-3/w) and meal (2/d) were anticipated variable on CRP ($R^2$=0.1268). Conclusion: It is thought that decreasing eating out and overeating might be important to prevent obesity. It is thought that decreasing drinking and fat eating might be important to improve serum lipids. It is thought that eating breakfast might be important to decrease CRP.

This study examines and analyzes a variety of apartment roof style for 147 apartment complexes built in the Gwangju metropolitan city in order to determine the style that is most preferred. The results of this study are as follows. Most of apartment houses built in the Gwangju metropolitan city are 11 to 15 stories followed by apartments that have less than 5 stories, with fewer apartments that have 16 to 20 stories. According to roof styles, the eyebrow roof A type is the most common, followed by the plane roof A type, the sloped roof B type and the sloped roof C type, while 2/3 of all roof types have either an eyebrow roof A type or a plane roof A type. Using images of these roof types to determine those that are preferred, the decorative roof C type is most preferred, followed by the sloped roof B and C types. According to recognition of adjective pairs, decorative roof C type showed a higher recognition for the categories of unique, decorative, three dimensional and novel, the sloped roof B type showed a higher recognition for the categories of three dimensional, decorative and structured while the sloped roof C type showed a higher recognition in the decorative, novel, varied and three dimensional categories. In the correlations between image preference and recognition scale of roof styles of apartment houses, decorative roof C type showed a significant correlation between adjective pairs with the calm image, the sloped roof B type with the intimate image, while the sloped roof C type showed a correlation between static and ordered with the easy image. Therefore, for the design of future apartment roofs, decorative roof C type requires more consideration of visual aspects that are related to a sense of unity, while further morphological factors needs to be adopted with sloped roof B and C types.

HMR is a home-style food product designed for convenience and cooked outside the home leaving out cumbersome cooking process and consumed at home. The present paper aims to find out factors that influence the consumption of HMR by analyzing data on food consumption during the 3 years between December 2010 and November 2013. Following the classification of Costa et al. (2001), this study categorized HMR products as 3 types as follows: C1 (ready to eat), C2 (ready to heat) and C3 (ready to cook), and examined factors affecting purchase rate and per capita purchase price for each type of HMR product. The results of our analysis show that only the purchase rate of C3 products was influenced by whether the purchaser was housewife with job or not. For those who do not live together with parents, per capita purchase price for HMR was high; and the more they ate out, the higher the purchase rate of HMR was.
