  • The objective of this study was to develop mixed seasoning products with Korean chili peppers(Capsicum annuum L.) and examine their characteristics based on a sensory evaluation. One-hundred chili pepper-related products were collected from American local favorites and analyzed for composition. Four different seasonings were prepared for the value-added seasoning products, and their sensory characteristics were measured. The Korean fish chili seasoning product showed higher overall acceptability, compared to local American seasoning(McCormick). The completed Korean chili seasoning products contained red pepper(20%), various herbs(31.7%), salt(11.5%), mushroom(8.6%), garlic(8.5%), curry, paprika(5.7%), and citron(2.8%). These results suggest the possibility of substituting mixed seasonings from foreign countries into Korean dishes.

  • This studied area is divided into the mountains and the valleys. The former is nearly consisted of the badland, the latter is consisted of alluvial plains in the valley, fluvial terrace at the side of the river, alluvial fans between mountains and river terrace. There are many tors, mushroom rocks, sugarloaves, weathering pits, castle coppies, columnar rocks, pinnacles, balanced rocks carved on tuff by means of erosion in the Chiricahua Nat'l Monument. Willcox Playa is alkalic crust where was lake in pleistocene epoch at the time wetter than present. Alkalic crust was made of Ca, Na, K etc. There are sand dunes around here where was lake side in the past. We found many kinds of fossils at the 2,000ft thick horizons of valley alluvium. Pediment and alluvium bordered at the base of Mt. Dragoon wavily. Exfoliation and spalling and sheeting resulted in boulders around here. Tucson is alluvial plain filled in thick 7,0000ft valley. Volcano, fault, erosion, alluvium were and are processing in this area.

  • In 2017, we collected a wood-decay fungus growing on a dead and decaying herbaceous plant (Reynoutria sachalinensis (F. Schmidt) Nakai) in Dokdo, the far-eastern island of South Korea. Morphologically, this species is characterized by resupinate, coriaceous to corky basidiocarps, poroid hymenophores, pseudodimitic hyphal system, and ellipsoid basidiospores. Based on morphological observation and internal transcribed spacer of ribosomal DNA, the fungus was identified as Xylodon flaviporus (Berk. & M.A. Curtis ex Cooke) Riebesehl & Langer. It is only the second macrofungal species reported from Dokdo, and R. sachalinensis is the first herbaceous plant to be identified as a host for X. flaviporus.

  • In order to investigate the emission pattern of sulphur dioxide gas from the soils in the plastic film house, the amounts of sulphur dioxide gas emitted from soils was periodically measured either in the plastic film house condition or in the incubator where the interior temperature was controlled to 10, 20. 30 and $40^{\circ}C$. Each soil was mixed with either mushroom, poultry, pig or fish meal compost at the rate of 0, 10, 20, 30, 40 and 50g/kg for individual treatment and then treated with addition of 50, 100, 150 and 200ml of water. A significant increase in the emission of sulphur dioxide gas was observed in the treatment of fish meal compost and such increase was initiated from the rate of l0g/kg, while little difference was observed in other treatments. Compared to upland soils, as control, the horticultural soils containing higher sulphur content emitted more sulphur dioxide. The emission of sulphur dioxide was favoured as temperature increased and was highest with the addition of 150ml of water.

  • Objectives: This study was conducted to assess the eating behavior, growth, and dietary practices of children aged 3~5 years living in the Seoul and Gyeonggi Provinces. Methods: Self-administered questionnaires were completed by 237 mothers of preschool children between April and June 2018. Z-scores for weight-for-age, height-for-age, and BMI-for-age were calculated to determine the children's growth status. Dietary practices were evaluated using the nutrition quotient for Korean preschoolers (NQ-P). Results: In our study, 29.5% of children were in the eating-small-amounts group, 46.8% of children were in the neophobic behavior group, and 61.2% of children were in the refusal-of-specific food group. Specific foods found to have a high frequency of rejection are listed in descending order as follows: shellfish, soy, mushroom, shrimp, vegetables, milk, eggs, yogurt, seaweed, meat, fruits, and fish. The eating-small-amounts group had lower Z-scores for weight-for-age, height-for-age, and BMI-for-age than the non-picky eaters' group. Compared to the non-picky eaters' group, the eating-small-amounts group of picky eaters had lower scores on the moderation and environment items of the NQ-P, the neophobic behavior group had lower scores on the balance and environment items of the NQ-P, and the refusal-of-specific food group had lower scores on the balance, moderation, and environment items of the NQ-P. Conclusions: Children classified with picky eating behavior had lower growth and development, lower diet diversity, less balanced food intake, and had greater difficulty in abstaining from eating unhealthy foods than non-picky eaters. Therefore, a lot of patience and intensive efforts are needed to encourage children to encounter, experience, and accept unfamiliar food. It is more effective to provide eating behavior guidance by gently encouraging children, than by being strict and forceful. Besides, since the eating behavior of children is influenced maximally by the dietary lifestyle at their homes, it is important to ensure that a healthy dietary lifestyle is maintained at home.

  • Four dietary fiber enriched menus for the aged were developed and physicochemical were analyzed. Major foods enriching the dietary fiber were as following; kimchi & bean sprouts soup and sweet potato for menu 1, chamcheunamul and grape for menu 2, mushroom and kimchi for menu 3, dried radish leaves and green pepper for menu 4. One portion of calorie, carbohydrate, protein and fats for the aged were calculated as 567 kcal, 92.8 g, 21.3 g and 12.6 g, respectively based on recommended daily allowances for adults. Dietary fiber content increased in the menus 1, 2, 3 and 4 were 17.27%, 20.84%, 16.91%, and 23.64%, respectively. The menu 1 had significantly the highest acceptance scores among the rice, soups, side dishes and overall desirability with the acceptance sores of 4.77, 4.58, 4.62 and 4.69, respectively(p<0.05). Female showed significantly the higher acceptance scores of all of the enriched fiber menu than those of male. Moisture contents of the boiled rice with barely in menu 3 had significantly the highest value of all(p<0.05) and the side dishes of all menus did not show any significant differences at p<0.05. The pH value of boiled rice with barely in menu 3 was significantly the highest and menu 1 of kimchi & bean sprouts soup had significantly the lowest pH values(p<0.05). Hunter L value was significantly the highest in boiled rice with barley. The dietary fiber enriched menus were successfully developed for application and standardization in the meal service planning for the aged as one of trials of basic data collection.

  • Termitomyces albuminosus has been recognized to have the best mushrooms in China, in terms of taste and aroma. The efficacy of these mushrooms has been recorded in the botanical list. However, research on the development of their artificial culture methods is necessary. In this study, we prepared an organic solvent extract and a hot water extract to understand the development of compounds and functional foods with antioxidant and anti-inflammatory activities. The IC50 value of DPPH radical scavenging activity of the hot water extract (TA4) was 1.5 mg/mL and the IC50 value of the MeOH fraction (TA2) was 1.93 mg/mL. The anti-inflammatory activity was investigated by the inhibition of NO production. EtOAc fraction (TA1) is a crude extract, but 79% of NO production was inhibited at 100 ㎍/mL. NO was not produced at 200 ㎍/mL. TA1-5-6, from TA1 inhibited NO production by 15% as compared to the positive control at 15 ㎍/mL, and completely inhibited NO production at 30 ㎍/mL. No cytotoxicity was observed at 50 ㎍/mL. TA2-1-5 from the MeOH fraction (TA2) inhibited more than 75% of NO production at 30 ㎍/mL; cytotoxicity was very low even at 50 ㎍/mL. In conclusion, by selective solvent selection, it was possible to manufacture an extract with no cytotoxicity and excellent biological activities. Furthermore, the extracts showed potential for developing various functional foods and drugs.

  • This study was carried out to offer the successive method of cultivation and increase the productivity of mushroom yield with good quality through the elevation of rate of spawn development for Lentinus edodes. Studied about the analysis of current management of actural cultivation, a base of these, researched and presented for the upward method of productivity through an experiment of the high rate of spawn development and cultivation, putting first cultural environment. The results obtained were as follows ; 1. As the result of the analysis of current management in actural cultivation, many cultivators had a tendency to neglect managements of cultivation. These were reason for the deficiency of labour, funds and the lack of knowledge of cultivation, etc. 2. Water contents in bed logs according to the date of inoculation was shown as the decreasing order of 28.63%(3/12), 25.20%(3/25) and 23.19%(4/10). For the purpose of the maintenance of the water contents, the full-development of mycelium in bed logs and the dispersion of labour, the date of inoculation should be started in the early March. 3. The difference of the rate of spawn development among species was not shown, 100%(Mori 465). 98.98%(Mori 3046) on the spawn in high temperature and 98.97%(Mori 290) on the spawn in low temperature. The relative rate of spawn development was 97.70%(Mori 465), 82.45%(Mori 3046) on the spawn in high temperature and 88.87%(Mori 290) on the spawn in low temperature, it showed the difference. The spawn should be selected carefully in the future, as the spawn of cultivater's preference showed the difference for the development of mycelium. 4. The rate of spawn development following the date of inoculation was 100.0%(3/12), 98.98%(3/25) and 96.79%(4/10) on the spawn in high temperature and 99.09%(3/12), 98.97%(3/25) and 97.89% (4/10) in low temperature, it showed little difference. And the relative rate of spawn development was 97.70%(3/12), 82.45%(3/25) and 81.42%(4/10) on the spawn in high temperature and 93.27%(3/12), 89.67%(3/25) and 88.87%(4/10) that in low temperature, As the result of the relative rate, the time of inoculation of spawn should begin in the early March. 5. The height of stock logs on temporary placing should be less than 60cm at most on the surface, because of the low rate of water contents.

  • Korean agriculture has encountered two problems. One is internal income disparity between rural and urbarn area and the other is external Uruguay Round trade problems as an abolition of direct and indirect import barriers, reduction in export subsidies and to reduce internal price supports. These problems will be brought severe farm problems such as decreasing farm household income and repressing agricultural growth in the near future. Considering the above inevitable facts Korean government has implemented several development projects such as rural industrial area development project, rural special production area development project, leisuresight seeing farm development project, traditional food development project, unskilled labor training project for off-farm employment and so on, to increase farm household income through off-farm income increase. This study was mainly concentrated on the identification of operational problems and post evaluation of the rural special production area development projects which aimed at increasing non-farm incomes and giving employment opportunity for rural farmers in small factories processing regional special farm products and mine products. The main findings and problems to be solved for the successful project implementation are as followed ; 1. Total number of the special production area development projects as of the end of 1991 was amount to 138, and total number of farm household participated were estimated at 2,079, and total amount of off-farm income per farm household was reached to 3,011 thousand won. 2. The total number of processed special products have increased from 21 items in 1981 to 56 items in 1991. On the other hand the total number of farm household participated in the projects have decreased from 2,518 to 2,079 during same period. 3. Total amount of investment for the projects has increased from 1,429 million won in 1981 to 24,760 million won in 1991 but the rate of G'T loan of the total investment has reduced from 24.5% to 5.2% during same period. 4. 138 special production area development project are classified into 6 kinds of commodity groups such as 19 of general industrial good production areas, 52 of folks-industrial art objects production areas, 39 of food processing areas, 9 of fiber and texstile processing areas, 18 of agricultural and fishery inputs processing areas and 1 of stone processing area. 5. The total production value in 1990 was estimated 20,169 million won of which export was amount to 2,627 million won. 6. The finacial rate of return of the UNGOK KUGIJA Tea processing Project operated by UNGOK coops and BAKSAN ginseng tea processing project were estimated at 45.4% (B/C Ratio=1.17, NPV=152.5 million won) and 17.7% (B/C Ratio=1.12, NPV=120.2 million won) respectively. 7. More favorite terms and condition of the loan including collateral problems have to be given to farmers participated. Heavy investment and G'T subsidy policies should be started for the successful project implementation anf farm household income increase. 8. To expand market demand of the rural special goods G'T have to provide special program of TV or other mass media for commodity propaganda and the total cost concerned must be supported by G'T subsidy. 9. The special farm products as GUGUJA,MOSI'Ramie', Ginseng. SOGOKJU,HEMP,Mushroom.DUGYUNJU and Chesnut processing projects have to be propelled and expanded for off-farm income increase in Chung Nam Province. 10. Direct operational pattern of the special production area by coops is more favorable to farmers and recommendable considering with off-farm income increase and market demand creation throughout Korea. 11. In rural area, special organizations for project appraisal are not exist. Accordingly special training program, project appraisal, formulation and preparation for civil servants concerned have to be prepared for project selection and sound implementation under limited budget and financial support.
