The spider fauna of Namhai Island was investigated from 21 to 25 Aug 1998. As a result,81 species of 43 genera under 15 families were collected. Identified spiders are composed of 30.8% Palaearctic, 28.4% Palaearctic and Oriental, 6.1% Holarctic, 2.4% Oriental, and 3.7% Cosmopolitan species. Araneid, salticid and theridiid spiders appeared to be dominant among the spiders. Common species with Japan and China were 56(69.1%) AND 55 (67.1%) species, respectively.

33-year old female was admitted chest surgery department for evaluation of mild chest pain. Chest plain film showed right anterior mediastinal mass and small metastatic daughter mass ipsilateral side. Exploratory thoracotomy was performed 24th Aug. 83 revealed that small nodular parenchymal mass at right middle lobe and large cystic mass at anterior mediastinum which was connected with anterior mediastinal fat. Histological examination confirmed diagnosis as pulmonary hamartoma and thymic cyst individually. We successfully treated these two masses by wedge resection and excision. Although postoperative course was uneventful, the cause and associated relationship between two tumor origin were obscure.

The studies on the carotenoids in the viscera the brine shrimp(Penaeus Orientalis Kishinouye) have been carried out. The brine shrimps were caught around the western coastal area of Korea from Aug. to Oct. The individual carotenoids in the acetone extracts were separated and purified by the silica gel TLC. Two isolated carotenoids were investigated and identified by epoxide test, partition test, alkaline hydrolysis, reduction with sodium borohydride and visible absorption spectrophqtometry. As the results of the series of experiments, esterified Astaxanthin was discovered as one of main pigments of Penaeus Orientalis Kishinouye.

Some bryozoans were collected from the subtidal zone of Manjaedo Island on 23 Aug. 1988. Two species of them, Crepidacantha poissoni (Audouin, 1826) and Hippothoa distans MacGillivray, 1869 turned out to be new to the Korean fauna. The family Crepidacanthidae is new to Korea.

The purpose of this study was to obtain the basic data on clothing habits for health promotion through the investigation of clothing weight by month and season. Thirty six subjects (18 males and females twenties) were composed to obtain the clothing weight(Total clothing weight) for a year. And then clothing weight was grouped in to four seasons : spring(Mar-May) Summer(Jun-Aug) Fall(Sep-Nov) and Winter(Dec-Feb). The data of males and females were respectively divided into three groups by cluster analysis with clothing weight. 1. The clothing weight of male and female were the heaviest in jan, that of male were smallest in July female in Aug. 2. The clothing weight mean of male(996g/m2) were heavier than that of female(894g/m2) for year. The seasonal clothing weight of male culminated in Winter(1179g/m2) and decreased respectively : Spring (973g/m2) Fall(879g/m2) and summer(559g/m2) The seasonal clothing weight of female culminated in Winter (1068g/m2) and decreased respectively ; Fall(865g/m2) Spring(835g/m2) and summer(479g/m2). The seasonal clothing weight variations were significantly different in each season(p<0.01) but they were insignificantly different between Spring and Fall. middle and light. There was individual differences in the clothing weight especially large in Winter and Spring and small in Summer and Fall. 4. Lower inner clothing weight was the lowest fluctuant all around year upper outer clothing weight was the most fluctuant. So he/she controled upper outer clothing to deal with thermal environment. He/she pretended natural textiles such as cotton and wool to synthetic textiles.

The purposes of this study was to identify characteristics of total coordination in the pursuit fashion sensibility among women their 20's. A self-administered questionnaire was used for data collection from 410 women in their 20's. Data collection was conducted Aug. 5 to Aug. 15, 2009. Most women emphasized on clothing for total coordination and utilized clothing color and style as a selection criteria. They tried to match makeup and clothing, and spent more time considering makeup, hair styles, and fashion accessaries than clothing for their total coordination. Factors of fashion sensibility included luxury and fashion, casualness and ethnicity, modernity, sociality, activity, and sexual attractiveness and women were segmented into fashionably sensible intermediate, low, and high groups according to their fashion sensibility. The fashionably sensible intermediate group predominantly encompassed women who were unmarried or in their late 20's, unemployed, highly educated, or of low economic status, preferred to mixing and matching colors, and who utilized their individuality or makeup color for total coordination. The fashionably sensible low group encompassed homemakers, in their early 20's, high school graduates or university students, who utilized their clothing or hair color within their total coordination criteria. The fashionably sensible high group encompassed unmarried career women in their mid 20's or of high economic status, who spent much money on their clothing, makeup, hair styles, and fashion accessaries, who preferred achromatic, warm or cool colors, and utilized their individuality or fashion color.

Beamforming technique at the ground station is known to be effective in obtaining coverage extension or SNR gain for communication with unmanned aerial vehicle (UAV). When a UAV moves, periodic beam tracking is necessary to maintain beam gain. In order to track beams for multiple UAVs, the ground station needs to receive different preamble sequences from multiple UAVs. In this paper, a preamble sequence design technique is proposed for beam tracking in a GMSK-based communication system with multiple UAVs. Hadamard sequence is considered for the design of preamble sequence due to its ideal cross-correlation property. A preamble sequence appropriate for a GMSK communication system with multiple UAVs is proposed after analyzing the properties of received signal in a GMSK system with the input of Hadamard sequence.

This study was conducted to investigate suitable rice cultivars for various rice based cropping systems in a paddy field in the Yeongnam plain area. Thirteen rice cultivars (5 early, 3 medium and 5 mid-late maturing cultivars) and three transplanting dates (June 5, June 25 and July 5) were evaluated in this study. The mid-late and early maturing cultivars for the July 5 and June 25 transplanting headed before August 30 which is the safe heading date in the Yeongnam plain area, ranging from Aug. 26 - 28 and Aug. 18 - 23, respectively. The safe harvest time of rice for double and triple cropping systems should be before the middle of October for the cultivation of the succeeding winter crops. The rice yield was the highest for the June 5 transplanting regardless of the rice cultivars, and it gradually decreased as the transplanting date was delayed from June 5 to July 5 due to a decrease in the spikelet numbers per panicle number and in the ripened grain rate. In contrast, the other yield parameters that include the panicle number per $m^2$, the 1,000-brown rice weight, and the ripened grain ratio were not significantly affected. The result indicates that based on the milled rice, heading time and harvest time, a medium maturing cultivar (Haiami and Samdeog) would be applicable to a winter barley/wheat, garlic/onion-summer rice double cropping, while a mid-late cultivar (Saeilmi, Saenuri and Hyunpoom) would be suitable for a spring potato/waxy corn-summer rice double cropping in the Yeongnam plain area. On the other hand, an early maturing cultivar (Unkwang, Jokwang and Haedamssal) would be preferable for a triple cropping because of the short growth period of rice.
