A newly devised dryer with heated air for the farm products, especially suited for high water content materials such as red pepper, Beer ground, each Vegetables, and Low water content materials such as Rough rice was tested for its thermal efficiency and drying mechanism, and the optimum conditions for each sample were established. In order to improve the present rural situation of drying farm products which entirely dependent upon natural solar radiation, a study upon an economic multi-parpose dryer was conducted. A series of drying tests were run first with red pepper which is one of the important cash crop in Korean farm. And successive series of tests were also run with such proaucts as garlic, sweet potatoes, green onion, radish, Beer ground and Rough rice. The results from the above experiment in drying system with heat dryer can be summarized as follows. 1. Drying duration could be shortened by the tempering effect in high water content crop such as red pepper and beer ground. 2. The color changes occured in around 20% water content in red pepper. The degree of color change was heavily affected by high temperature and short drying duration. 3. The drying condition of red pepper was most favourable at the temperature of 85$^{\circ}C$ in early stage and 80$^{\circ}C$ in middle stage and 75$^{\circ}C$ at the final stage, and with the air rate of 0.81㎥/sec and with sample amount of 200kg. 4. The drying condition of Rough rice(I.R.667) was most favourable at the templature of 40$^{\circ}C$ in early stage and 35$^{\circ}C$ in middle stage and final stage and with the air rate of 0.2㎥/sec and with sample amount of 75kg. 5. In order to prevent the color change of red pepper and to assure high efficiency in drying mechanism, it was necessary to lower the temperature as the time passes in drying process. 6. For vege tables, the drying rate were short in early stage and there was also tempering effect. However, for garlics, Constant drying rates through the early and final stages were observed and there were no tempering effects. 7. The drying condition or capability were as follows; Sample drying temp($^{\circ}C$) amount of material(kg) drying time(hr) Red pepper 85 200 9 Garlic 85 150 7 Sweet potato 85 200 6 Green Onion 85 200 4 Carrot 85 200 4 Radish 90 250 4 Rough rice(I.R.667) 35 75 4 Beer ground 90 320 3 Considering the above result of experiments, if this kind of dryers were distributed Korean farm and the optimun process were practiced in rural area, it would certainly help them improving the qualites of their product preventing their undue losses, and thus assuring an increase of Korean farm income and promotion of their living standards.

With the recent rapid improvement in the standards of life and westernization of dietary lifestyles, the consumption of high-calorie diets such as high-fat and high-protein red meat and instant foods has increased, while less vegetables containing dietary fiber are consumed. In addition to that, stress, erroneous dietary behaviors, and contaminated environments are linked to the risk of developing ulcerative colitis, which is on the rise. Another cause of ulcerative colitis is that involve laxative abuse, including repeated, frequent use of laxatives, and include such conditions as deteriorated bowel function, irritable bowel syndrome, diarrhea, intestinal inflammation, etc. The present study aimed to investigate the comparative evaluation of pharmacological efficacy between sulfasalazine alone and combination with herbal medicine on dextran sodium sulfate (DSS)-induced UC in mice. Balb/c mice received 5% DSS in drinking water for 7 days to induce colitis. Animals were divided into five groups (n = 9): group I-normal group, group II-DSS control group, group III-DSS + sulfasalazine (30 mg/kg), group IV-DSS + sulfasalazine (60 mg/kg), group V-DSS + sulfasalazine (30 mg/kg) + Radish Extract mixture (30 mg /kg) (SRE). DSS-treated mice developed symptoms similar to those of human UC, such as severe bloody diarrhea and weight loss. SRE supplementation, as well as sulfasalazine, suppressed colonic length and mucosal inflammatory infiltration. In addition, SRE treatment significantly reduced the expression of pro-inflammatory signaling molecules through suppression both mitogen-activated protein kinases (MAPK) and nuclear factor-kappa B (NF-κB) signaling pathways, and prevented the apoptosis of colon. Moreover, SRE administration significantly led to the up-regulation of antioxidant enzyme including SOD and Catalase. This is the first report that Radish extract mixture combined with sulfasalazine protects against experimental UC via the inhibition of both inflammation and apoptosis, very similar to the standard-of-care sulfasalazine.

본 연구에서는 나주지역을 사례로 기후변화가 농업생태에 미치는 영향을 파악하고자 하였다. 이를 위하여 나주지역의 농업 관련 통계자료와 기후 자료를 분석하였다. 벼와 보리의 출수기는 일러지는 경향으로 각각 출수 30일 이전의 평균기온과 음의 상관관계가 있다. 일러진 출수기 때문에 등숙기간의 평균기온이 상승하여 여름철 작물인 벼의 단위면적당 낟알 수는 감소한 반면에 겨울철 작물인 보리의 단위면적당 낟알 수는 증가하였다. 그러므로 기온이 오늘날과 같은 추세로 상승한다면 벼의 수량은 감소하고 보리의 수량은 증가할 것으로 예측할 수 있다. 배의 발아기 및 개화기와 만개기는 점차 일러지는 경향이며, 발아기는 2월에서 3월까지의 평균기온과, 개화기 및 만개기는 2월에서 4월까지의 평균기온과 음의 상관관계가 있다. 배의 당도와 과중은 증가하는 경향이며, 각각8월과9월의 평균기온과 양의 상관관계가 있다. 이와 같이 기온 상승은 배의 당도 및 과중 등 생육상태에 긍정적인 영향을 미칠 것으로 예상되지만 발아 및 개화기가 빨라짐에 따라 저온 피해 및 늦서리 피해를 입을 수 있다. 배추와 무의 초장은 모두 감소하는 경향이며, 9월 최고기온과 음의 상관을 보인다. 반면 고추의 착과수는 최근 증가하는 경향이며, 8월의 최저기온과 음의 상관관계가 있다. 기온 상승은 저온성 작물인 배추와 무의 생육 저하를 초래할 수 있으나 고온성 작물인 고추의 생육에는 긍정적인 영향이 예측된다.

Physicochemical and sensory characteristics of Kakdugi substituted red pepper powder with red paprika powder during fermentation at 1$0^{\circ}C$ were compared with those of the control. The fermentation patterns of two Kimchies were similar. While the pH and the acidity of the control were 3.88 and 0.691%(as lactic acid), respectively, those of paprika, 3.85 and 0.690%(as lactic acid), respectively on the 10th day of fermentation, which is the optimal ripe time. Reducing sugar content and Lactobacilli number of paprika Kakdugi were higher than those of the control. The hardness and fracturability of Kakdugi radish were not significantly different from those of the control during fermentation. The Hunter color L, a and b values of both Kakdugies increased gradually until l0th day and then decreased. The a and ASTA value of paprika Kakdugi was higher than that of control, which is consistent with the results of sensory evaluation. Capsaicin and dihydrocapsaicin analyzed by HPLC were not detected in paprika Kakdugi. Sensory evaluation (unstructured scale, 10 points) showed the score of hot taste f3r paprika Kakdugi was lower than that of the control(p<0.05), whereas the score of over-all acceptabillity for paprika Kakdugi(8.0) was higher than those of control(6.1).

This study was undertaken to investigate the knowledge and the use of Korea traditional basic side dishes, Jangachies, by housewives. Among the 58 kinds Jangachies, the most well-known Jangachies (above 80% of subjects) turned out to be Perilla leaf, Red pepper leaf, Garlic, Young stem of garlic, Green red leaf, Cucumber and dried Radish Jangachi in the order. In cooking experience of Jangachi, 40% of subjects in Perilla leaf, 28.0% in Green red pepper, 24.8% in Garlic and 24.1% in Red pepper leaf Jangachi have cooked frequently. The proportion of subjests who has bought the marketed Jangachi products were 51.6%. Major problem of that products was pointed out for a sanitary condition, high price and poor taste. If marketed Jangachies were improved over the aspects, the proportion of subjects who would buy the products was 76.2%. The frequency of Jangachi intake was very low on a average due to too salty taste and the difficulty in preparation. The older in age, the more in interest level for Jangachi (p<0.05). 39.6% of subject have had preparation ability of Jangachies. With increasing age (p<0.01), decreasing education level (p<0.01) and those who live in rural area (p<0.05), preparation ability of Jangachi tended to be higher.
