"Boseog" is a new japonica rice cultivar developed from the three way cross of Kinuhikari//HR19621AC6/Sobibyeo and registered by the rice breeding team of Department of Rice and Winter Cereal Crop, NICS, RDA in 2008. This cultivar has about 110 days of growth duration from transplanting to harvesting in northern plain, northern and southern mid-mountainous area of Korea. This cultivar is about 72 cm in culm length and tolerant to lodging. In the reaction to biotic and abiotic stresses, it shows resistance to leaf blast, but susceptibility to bacterial blight, virus diseases and insect pests. The milled rice of "Boseog" exhibits translucent, relatively clear non-glutinous endosperm and midium short grain. It has similar amylose content(18.0%), lower protein content(6.3%), and similar palatability of cooked rice compared to Odaebyeo. The milled rice yield of this variety is about 5.03 MT/ha in local adaptability test. "Boseog" would be adaptable for ordinary transplanting in northern plain, mid-mountainous and southern mountainous area of Korea.

The objectives of this study are developing the new types of elderly abuse and finding the variables affecting the new elderly abuse type. And This is at suggesting the intervention strategies preventing the elderly abuse. The 350 cases of elderly abuse reported in Elder Protection Agency was analysed. Data is analyzed by using statistical techniques including cluster analysis and logit-regression. New type of elderly abuse is "violent elderly abuse" and "avoiding elderly abuse". Violent elderly abuse is very connected with directly violence speech and behavior and avoiding elderly abuse is connected with neglect and abandonment, self-neglect. The elderly's instrumental activity of daily living and education, the offender's sex and education and living together type of the elderly - the offender, and the offender's care burden are the casual factors of the new type of elderly abuse. Based on the results, the various service programmes for the abused elderly is developed and implemented.

최근 밀(Triticum aestivum L.) 소비량이 꾸준히 증가하고 있어 국내 밀 자급률 증대를 위한 노력이 필요하다. 그러나 우리나라는 작물을 재배할 수 있는 농경지가 한정되어 있어 벼 수확 후 휴경 논을 이용하여 겨울철에 밀을 재배하거나, 하계 소득 작물과 연계하여 겨울철에 밀을 생산할 수 있는 방안을 모색할 필요가 있다. 본 연구에서는 남부지역 평야지 논을 이용하여 밭작물 중심 다모작 작부체계를 제시함과 동시에 밀을 재배하여 생육 특성과 수확량 변화를 살펴보았다. 단위면적당 수수 및 종실 수량은 작부이력에 밭작물이 포함된 다년 다모작 작형(들깨-IRG-참깨-밀, 콩-IRG-참깨-밀)이 다년 벼-밀 이모작이나 벼-IRG-참깨-밀 다모작에 비해 많았으며, 특히 들깨와 콩이 포함된 작부체계에서 많았다. 밀 품종 간 비교에서는 금강밀이 조경밀에 비해 출수기와 성숙기가 2~3일 빨랐지만 종실 수량은 100 kg/10a 이상 적어, 동일한 환경조건에서 조경밀이 금강밀에 비해 곡물 생산성 측면에서 유리할 것으로 보인다. 더군다나 조경밀은 조숙 다수성 경질밀로 전국에 재배가 가능하고, 단백질 함량이 높고 강력분의 특성을 보여 제빵용으로 많이 활용되고 있다. 본 연구에서 조경밀은 단백질이 10% 이하로 낮고 아밀로스는 28.4%로 높은데 반해, 금강밀은 단백질이 11.0%로 높고 아밀로스는 26.6%로 낮아 제과·제빵에 있어서, 금강밀이 좀 더 유용할 것으로 보인다. 밀가루의 Falling number는 조경밀과 금강밀 모두 350초 이상으로 높아 수발아로 인해 전분의 분해가 일어나지 않은 건전한 상태의 곡립임을 알 수 있다. 그리고 gluten 함량도 조경밀과 금강밀 모두 유사하게 높았으며, gluten 지수는 금강밀이 좀 더 높았다. 이상의 결과를 토대로 밀 수확량을 증가시키기 위해서는 기존의 벼-밀 이모작 보다 들깨-IRG-참깨-밀이나 콩-IRG-참깨-밀 등의 다년 다모작 작형이 좀 더 유리할 것으로 보인다.

Objectives : To study the effects of Kumsooyukkun-jeon on asthma. Methods : Asthma was induced to Balb/c mice with ovalbumin using the method of Hatfield et al. We measured the histological profiles of lung and trachea, numbers of cellular compartments in the bronchoalveolar lavage fluid (BALF), numbers and morphology of the mast cells in the trachea, numbers of mucous-secretory cells in the bronchus, morphology of the bronchus, ultramicroscopical appearance of surface of trachea and number of cilia and mucous-secretory cells by scanning electron microscope. Results : 1. Hypertrophy of mucous membrane of trachea and bronchus and bronchioles in the lung, peritracheal, peribronchus and peribronchiolar inflammatory cell infiltration, and mucoid exudate deposition the lumen were observed in control groups but these phenomena were recovered in the Kumsooyukkun-jeon groups. 2. Cellular compartments including neutrophil and eosinophil were increased in the BALF of control groups but these phenomena were recovered in the Kumsooyukkun-jeon groups. 3. Degranulation and decrease of the numbers of mast cells were detected in the trachea of control groups. However, these phenomena were recovered in the Kumsooyukkun-jeon groups. 4. Shedding, decrease of cilia cell and increase of mucous-secretory cells in the surface of the trachea were measured in control groups but these phenomena were recovered in the Kumsooyukkun-jeon groups. Conclusions : It is considered that Kumsooyukkun-jeon has somewhat favorable effects on asthma.

In this paper, Ka-band transceiver for road watch radar system is designed and fabricated. The transceiver for road watch radar system is composed of waveform generator, frequency generator. IF transceiver and RF up/down converter. The transceiver especially has 3 different waveform mode for target detection range. The transceiver had over 150 MHz bandwidth in Ka-band and 22 dBm output power. The receiver gain and noise figure was 30 dB and 4 dB respectively. The receive dynamic range was 65.28dB and amplitude imbalance and phase imbalance of I/Q channel was 0.3 dB and 1.8 degree respectively. The transceiver meets the required electrical performances through the individual tests.

The purpose of this study is to generate a proper regulation improvement direction of the public If project contract law through the current four contract methods and three methods of the awarding party of a contract method. The research method for this paper is derived from the written materials of the present public IT project contract law. Two problems have been processed in order to produce the results: the current contract methods and the awarding party of a contract method. The current contract methods consist of a competition contract, a private contract, and a supply methodology contract, The methods of the awarding party of a contract display a qualified evaluation regulation, the 2nd step competition bid, a standard cost separation tender, and a contract by a negotiation. The results exhibit that the general competition contract consists of four improvement items. The contract by a negotiation contains five improvement items. The group private contract has one improvement item. And the private contract includes one improvement item. These results implicate that the current public IT project contract law demands better improvement work for the ubiquitous Korea.

This study is on a seismic analysis of absorber rod in KMRR Reactivity Control Mechanism. The model being studied is two coaxial tubes(control absorber rod and flow tube) immersed in the water and partially coupled(overlap) by water gap. The hydrodynamic mass effects by the water in each surrounding conditions are considered in the model. The natural frequencies, stresses and displacements of the system due to Safe Shutdown Earthquake are computed in the cases of in-phase modes and out-of-phase modes of two coaxial tubes. The results show that maximum stresses are well below the allowable limit but the maximum displacements at the ends of both tubes are so much that the absorber rod contacts with the flow tube(or surrounding wall).

In the Edo period speaking of hair culture, common women wore decorative pigtail ribbons on the right, and twisted from side to side their tressed hair in such a manner as ungeunmeori and traemeori. Instead of gachae, common women used gogae made of their own hair, ungeunmeori on forehead, or jjokjinmeori at the back of head. During the Edo period, people women naturally exposed their necklines as a way of exposing their faces in the aesthetically ceremonial act of wearing make-up. As for lipsticks, they rouged extracts from red petals of safflowers mainly on their lips, and sometimes on their cheeks by blending this with white powder. Samurai families disliked women who wore thick lip makeup. In the latter period, women painted their necklines or foreheads black, applied a small amount of rouge on their cheeks thinly or thickly, and colored a reddish color into their fingernails by using petals and leaves of balsam flowers. Despite the chronological and spatial proximity of the King Jeongjo period and the Edo period, it was found that there were no similarities between two countries' cosmetic cultures. Moreover, it was discovered that current TV dramas were being produced, even not based on historical evidence in the Jeongjo period.
