The polycrystalline CdS of large scale were grown by chemical pyrolysis deposition for Cu2S/CdS heterojunction solar cells. For high quality CdS polycrystalline thin films, the chemical solution was deposited on indium tin oxide(ITO) glasses at the temperature of 500℃ for 15 second and annealed at 350℃ for 20 minute or 500℃ for 30 second. To fabricate high efficiency solar cells, optical and electrical properties, morphology by SEM and x-ray diffraction on polycrystalline CdS thin films were investigated. From the I-V characteristics of Cu2S/CdS heterojunction, the open circuit voltage, Voc was 0.7 V and the short circuit current, Isc was 4.2 mA. We found that the fill factor(FF) was 0.5 and the efficiency was 2.5%.

The survey was carried out to obtain some fundmental data to improve the dietary life and to establish the nutritonal education and policy on inhabitants lived in isle area near by demilitarized zone in Korea. For this, 33 families in the area of Kyodong island located at Kanghwa-Gun, Kyungki province were randomly selected. Trained surveyors visited each house to survey the food and nutritional status in summer during 3 days in August, 1987. The results are summarized as follows; The number of foods they were taking totalled 17 categories and 134 kinds of which 104 kinds were vegetable foods. The average amount of food intake was 1465.3g per person per day, animal food occupied 9.6% only. The intake amount of fruit among vegetable foods, and fishes, shells, milk and eggs among animal foods was lower than the national average. Each proportion of carbohydrate, fat and protein to the total energy intake was 70.4%, 9.7% and 19.9%. The foods they used to take a lot were rice, potatoes, cucumbers, cabbage KIMCHIE and YULMOO KIMCHIE in order of their intake amount. The energy intake was 3064㎉ which is higher than nutritional requirements, and the energy ratio of cereals to the total energy in take is 76%. If the amount of fat intake is fixed to 20% of total energy intake, the amount of fat intake is 68g, but the actual amount of fat intake was only 33g. With an increase of total energy intake, supply of calcium and vitamin A should be increased much more.

Recently, an interest has developed in the use of whole green grains as functional food materials. The present study was conducted to provide the baseline data for the stable production of whole green grains in 20 cultivars of wheat by investigating the greenness of grain with maturation (from 20 th to 41 st day after heading, at an interval of 3 days). On the 20 th day after heading, the grains were dark green with a wrinkled long-oval shape. After the 35 th day of heading, the grains turned almost yellow with an oval shape. Their redness (‘a’ value of chromaticity) increased from the 20 th to 41 st days after heading, indicating a negative value up to the 32 nd day after heading. A significant decrease in their chlorophyll content was observed with maturation. The yield of whole green wheat grain (including greenish yellow grain) was the highest from the 32 nd to 35 th after heading. Therefore, we concluded that the optimal harvesting period for whole green wheat grain was from the 32 nd to 35 th day after heading. The heading time of various cultivars ranged from April 28 to May 5, the time of Jopummil cultivar grew the fastest among them, such as Gurumil, Alchanmil, but Dahongmil got the latest in heading time. The greenness of seven cultivars (Jeokjungmil, Keumkangmil, Jogyeongmil, Jopummil, Baekjungmil, Yeonbaekmil, and Milseongmil) was relatively higher than that of the others. The yield of greenish whole grain was relatively high in six cultivars (Alchanmil, Baekjungmil, Eunpamil, Yeonbaekmil, Dahongmil, and Urimil). Based on their greenness and yield, the Baekjungmil and Yeonbaekmil cultivars have been considered to be optimal for the production of whole green wheat grain.

This study was conducted to evaluate the effects of different sowing times (May 25, June 10, June 25, July 10, and July 25) on growth and yield of four proso millet (Panicum miliaceum L.) cultivars (Hwanggeumkijang, Manghongchal, Ibaekchal, and Hwangsilchal) at a cultivation area in Iksan, Jeonbuk Province. Heading and ripening times were delayed, with later sowing times in all cultivars, and the periods for heading and ripening were shortened. For sowing from May 25 to July 25, the growth stage was shorter by 40 days in Manghongchal, 38 days in Hwanggeumkijang, 36 days in Hwangsilchal, and 30 days in Ibaekchal. The culm length, ear length, ear width, and culm diameter differed significantly between the cultivars and sowing times. In particular, the culm and ear lengths were considerably reduced when the sowing time was delayed. The grain yield (kg/10a) of Hwanggeumkijang and Ibaekchal was 312 and 359 kg, respectively, for sowing on June 10; and that of Manhongchal and Hwangsilchal was 286 and 404 kg, respectively, for sowing on June 25. Thus, the optimum sowing time was June 25 for Hwanggeumkijang and Ibaekchal, and June 10 for Manhongchal and Hwangsilchal.

‘Jungmo1024’ is a blast resistant early maturing rice cultivar with high temperature tolerance during grain filling stage. ‘Jungmo1024’ was derived from a sodium azide treatment on ‘Suweon472’, a high yielding japonica elite line which was latterly registered as ‘Namil’.

우수한 사료자원으로 평가되는 케나프의 생산단가를 낮 추기 위하여 새만금 간척지 시험포에서 염농도 단계별 생육 및 수량을 관찰한 결과 케나프는 중·상정도의 내염성을 보 유한 작물로 평가할 수 있으며 충분한 제염이 이루어진다고 하면 간척지에서의 재배 가능성도 충분할 것으로 평가할 수 있었다. 염농도별 케나프의 발아력을 조사한 결과 토양 염 농도가 4.0 dS/m (=0.26%) 일 때 84%이던 케나프 발아율 이 5.0 dS/m (=0.32%) 에서는 18%로 급격히 떨어졌으며 6.0 dS/m (=0.39%) 에서는 발아율이 10%를 넘지 못하였다. 또한 생육 상황도 토양 염농도에 비례하여 급격히 떨어졌는 데 케나프는 줄기직경을 2.6 cm 이상으로 유지할 수 있을 경우 엽수가 유의할 수준으로 늘어나고 줄기부분에 대한 상 대적 무게비율이 증가하는 결과를 얻을 수 있었다. 이는 잎 의 분열을 촉진시킬 수 있는 충분한 생장량 확보가 줄기직 경 2.6 cm 이상에서부터 가능하다는 것을 의미하는데 새만 금에서는 토양 염농도 4.0 dS/m (=0.26%) 이하에서는 케나 프의 줄기직경을 2.6 cm 이상으로 유지하는 것이 가능하였 으나 염농도가 5.0 dS/m (=0.32%)를 넘어서게 되면 줄기직 경이 2.0 cm 이하로 엽수도 20~46% 감소하였다. 생육장해는 파종 후 1개월 경과부터 본격적으로 나타나기 시작하였 는데 엽 정단이 고사하고 주변 잎 들이 급격하게 황화 낙엽 되는 현상이 발생하였다. 케나프의 토양 염농도에 대한 수 량성을 분석한 결과 토양 염농도 4.0 dS/m (=0.26%) 까지 는 비간척지에 비해 수량이 최대 19% 하락하였으나 염농도간 차이는 크지 않았다. 그러나 토양 염농도가 4.0 dS/m (=0.26%) 를 넘어서는 5.0 dS/m (=0.32%) 에서는 비간척지의 51% 수준을 유지하는데 그쳤으며 토양 염농도 4.0 dS/m (=0.26%) 일 때의 수량에 비해서도 38% 감소하였다. 통계분석을 통 하여 간척지에서 수량성 감소를 80% 이내로 유지 할 수 있 는 토양 염농도를 산출해본 결과 토양 염농도가 4.2 dS/m 이내로 유지될 경우 케나프의 생산성은 80% 이상을 유지할 수 있었다.

In order to produce the high quality of dried-ear mushroom, various drying methods such as hot-air drying at 40~80˚C, freeze drying and drying in vinyl house were carried out. Drying hours of hot-air drying, freeze drying and drying in vinyl house were 12.5~21.5, 36.0 and 72.0 hrs, respectively. Vitamin D2 content of sample was the highest as 6.77μg/g DW in drying in vinyl house and then followed by freeze drying as 5.90μg/g DW and hot-air drying as 1.89~5.01μg/g DW. After dry, external appearance and color of mushrooms applied hot-air drying and drying in vinyl house were better than freeze-dried one. After rehydration, water uptake of sample in drying in vinyl house and hot-air drying at 50~60˚C were 17.8 and 19.3~21.0 times, respectively. The methods of drying in vinyl house and hot-air drying at 50~60˚C also led to high hardness, good shape and resilience. As the results of production of dried-ear mushroom with high quality, we suggest that the best method for drying is the drying in vinyl house due to not only high vitamin D2 content, good external appearance and color after drying but also high hardness and good shape after rehydration.

Kenaf (Hibiscus cannabinus L.) was recognized as a potential source of forage. But the domestic cultivation techniques are not set standards yet. So we tested the basic culture techniques during 2012~2013 for getting a high yield and good grade forage production system. The best seeding method for mechanized planting (corn planter used) was hill seeding with 20×20 cm seeding distance. When we treated hill seeding with 20×20 cm, the yield what we could get was 13,641 kg/10a and it was 32% more than that of conventional practice hill seeding with 20×30 cm seeding distance. The proper seeding date for getting high yield was May 1. In May 1, the yield per 10a was reached 13,423 kg, and it was 30% more than that of seeding at May 30. More over the crude protein content which was important factor for determinating forage nutritive value was 12.7% and it was higher 1.8% (relatively 16.5% high) than that of May 30 seeding. The most effective herbicide for kenaf was Fluazipof-p-butyl. It’s herbicidal rate was 97% and phyto-toxicity was less than 5%. Regional adaptability for Jeollabuk-Do including Imsil Gun, Kochang Gun and Sunchang Gun were identified that the stable cultivation were possible in these area with average yield 12,400 kg/10a and it was about 1.7 times as compared to corn harvest.

The objective of this study was to evaluate quality properties including amylose, alkali digestion value (ADV), texture and GABA (Gamma Amino-Butyric Acid) of brown rice and 1~5 mm germinated brown rice of Keunnun and Samkwang culitvars. The protein content of germinated brown rice showed increasing tendency according to shoot length, however, the difference was not statistically significant. The amylose content of all samples ranged from 15.0% to 16.0% in Keunnun and 17.0% to 18.0% in Samkwang, without significant differences. Compared to regular brown rice, germinated brown rice from both cultivars demonstrated reduced gel consistency, which contributed to the improved cooked rice texture. Especially, germinated brown rice had significantly lower setback values, which is correlated with high palatability of cooked rice. However, there was no significant difference in gel consistency between 1 mm and 2~5 mm germinated brown rice. GABA content in Keunnun increased by 3~5 times after germination process. In Samkwang, GABA content increased by 50 times (from 0.005 μg/g to 0.243~0.247 μg/g) after germination. The hardness of germinated brown rice was significantly lower than that of brown rice. However, there was no significant difference in hardness according to shoot length. Consequently, when processing germinate brown rice, it is recommended to maximize functional ingredients by germination while maintaining shoot length less than 2 mm.

As concerns have been raised about health effects of children's products containing hazardous chemicals on children, the Korea Ministry of Environment announced 135 environmental hazardous substances in children’s products (EHSCP) which were subject to risk assessment. Therefore, it is necessary to identify the current status of EHSCP for management due to their various exposure routes and types. In this study, we investigated the exposure assessment of EHSCP as well as relevant policies implemented in domestic and foreign countries. Domestic and foreign cases of detection of EHSCP were reviewed in the literature and websites of related agencies. Due to the lack of reference values for child-specific toxicity of EHSCP, those for adults and regulatory status of EHSCP were also investigated and reviewed with literature. The related agencies of foreign countries provided 13 child-specific reference doses (RfDs), 76 RfDs, and 42 reference concentrations as toxicity reference values of the EHSCP. Among substances investigated in the studies to assess exposure of hazardous substances in children’s products by the Korea Ministry of Environment, 23 substances were included in 135 EHSCP. The same studies identified 9 substances which were excluded from the 135 EHSCP. For regulatory status for hazardous substances in children’s products, 44 substances (32.6 %) and 84 substances (62.2 %) of 135 EHSCP were under regulation in Korea and foreign countries, respectively. In the present study, we found that a list of 135 EHSCP should be revised to ensure children’s safety.

온대지역의 벼 품종을 열대지역 재배시 불수출수로 인하여 수확량이 급감하는 경향을 보이는 데 중․만생종이 이러 한 환경변화에 더욱 민감하다. 이러한 장벽을 극복하고자 필리핀 국제벼연구소내 한국지소에서 열대지역에서도 정상적인 생육을 나타내는 ‘진미‘와 밥맛이 좋고 병해에 강한 ‘철원46호‘를 교배하여 열대지역에서도 잘 생육하여 수량성도 높으면서 병에도 강한 온대벼 ‘아세미(수원574호)‘를 개발하였다. 필리핀 현지에서는 간장이 66cm로 작 고 주당수수 12개 수당립수 84개였으며 등숙률을 보면 현지 품종(IR 72)의 등숙률이 63%인데 ‘아세미‘는 77%로 높았고 수확량도 헥타르 당 4∼5 톤으로서, 현지 품종인 ‘IR72’보다 10% 가까이 많았고, 밥맛도 좋았다. 우리나라 에서는 출수기가 8월1일로 ‘화성‘(8월 12일)보다 11일 빨랐으며 간장은 82cm, 수장 21cm, 수수 12개, 수당립수 109 개, 등숙률 83%였고 현미천립중이 22.5g인 중립종이다. 생리장해 저항성으로 유묘적고가 거의 없고 감수분열기 임실률도 높아 내랭성을 어느 정도 갖추고 있었다. 잎도열병 저항성은 보통 수준이었고 흰잎마름병에는 약하나 줄무늬잎마름병에는 강했다. 또한 심복백정도 백미완전미율 등 미질특성은 ‘화성‘과 비슷하였다. 수량성은 중북 부 내륙지와 중서부 해안지에서 ‘화성‘보다 10%정도 높았고 중북부 산간지에서는 ‘오대‘보다 13%높은 수준을 보 였다. 이처럼 ‘아세미‘는 열대지역이나 우리나라에서 잘 재배되는 것으로 보아 아시아 지역에 재배가 가능한 비감 광성 광지역적응성을 갖춘 벼 품종임이 확인되었다.
