  • A tunnel system of mushroom cultivation was designed to compare with the conventional cultivation method in Korea. The bed and air temperature during the phase II the tunnel system was more stably controlled than in the conventional house. The indipensable energy was much saved in the tunnel system than in the conventional method, as this system did not require additional heat supply in the phase II. Compost fermented in the tunnel was proved to contain higher total nitrogen and moisture than compost in the conventional house. Residual ammonia content of compost fermented in the tunnel did not exceed 300ppm. Mushlroom mycelial growth in the tunnel was as good as in conventional house. The tunnel system did not require additional heat supply during mycelial growth period. Mushroom yield and quality from the tunnel system was 5 per cent higher and better than that of the conventional method.

  • The need of reusing sewage sludge is highly increasing as the amount of domestic sewage sludge is growing and sewage management strategies were reinforced. Accordingly, in this research, we studied the composting possibility of sludge in sewage treatment plant J, using dryer facility with indirect system by conducting component analysis of dried sludge and experiment on cultivating crops. It was observed from the component analysis, that the dried sludge is appropriate for both decomposed manure standard of Ministry of Environment and fertilizer standard of Rural Development Administration. Besides, in the experiment on cultivating lettuce, the experimental group(soil + dried sludge) was superior to the control group(soil + bed soil) in apparent condition of leaves tensity and damage by disease and pest. In case of cultivating tomato, the experimental group showed stronger durability of fruits dangling on stems compared to the control group after 9 weeks. Consequently, the excess sludge dried by indirect heating system in the sewage treatment plant J is appropriate for the standard of both Ministry of Environment and Rural Development Administration and show good result in experiment on cultivating crops therefore it can be reused for composting.

  • The temperature of root zone was known as an important factor for the growth of crops and reduction of energy in greenhouse. The purpose of this study was to design the apposite inflow of calories per the unit area by comparison of temperature in the warmed and non-warmed soil. The energy needed for soil warming about pipe length showed the change of temperature on inflow and outflow as $2^{\circ}C{\sim}3^{\circ}C$(average $2.5^{\circ}C$). Therefore, the inflow per the unit hour was 3,450, 57,5 kcal/$h{\cdot}m^2$ on soil heating respectively. The non-warmed soil temperature in greenhouse made a difference by depth and it was partially affected inner temperature under 15 cm, but it was not above 15 cm. The soil temperature would be raised over $5^{\circ}C$ than non-warmed soil to increase effect of soil warming. Therefore, the inflow per the unit area that should be provided was about 100 kcal/$h{\cdot}m^2$.

  • This studies were carried out to investigate the effects of the management of curing barn and the use of supplemental heat on prevention of barn rot during the rainy season. The managemental methods of curing barn were combined with hanging spaces ranged from 15cm to 30cm and ventilating conditions. The supplemental heat was applied with oil burner and oil fan heater. Barn rot was reduced in the wider hanging spaces, and the effects of hanging spaces was larger with ventilating during curing. Barn rot decreased by ventilating condition than non-ventilation. The use of supplemental heat dropped to lower relative humidity in curing barn. Supplemental heat and forced-air movement greatly reduced barn rot in comparison with tobacco cured under natural conditions.

  • Extraction methods and instrumental analytical conditions were compared to establish a fast and appropriate analytical method to determine saikosaponins in Bupleurum falcatum. Using HPLC, analysis of diene-saikosaponin treated with 2% acid was faster than that of saikosaponin itself. Among various extraction methods, extraction by standing in methanol at room temperature showed highest efficieny, and extraction with boiling methanol was shorter in analytical time and showed good chromatogram. And we could analyze many samples faster using HPTLC but the analytical accuracy was low. In extraction and analysis of saikosaponins, extraction with boiling methanol and acidic treatment was fast and easy analytical method. And for selecting useful lines in component breeding, we think TLC method was better.

  • Purpose: The main question is systematic review of the published in Korea and foreign countries on warming therapy for surgical patients. Methods: The researchers searched at Medline, CINAHL, KERIS, Adult Nursing Association, Korean Society of Nursing Science, Korean Academy of fundamentals of Nursing, and National Assembly Library web site for the published on warming therapy for surgical patients from 1980 to 2008. Words for search were operation/surgery, warming, operation/surgery and warming. Studies were included randomized controlled trial, and there were no restrictions regarding operative phase and outcome measures. Results: 36 published researches that met the criteria were mostly published in foreign countries between 2000 and 2008 and focused on surgery with general anesthesia. Sample size ranged from 21 to 60 subjects, age range between 21 and 60 years of age. Thirty different warming therapies were reported, fifty-two different dependent variables. Outcome indicators included active external warming, intra-operative, and body temperature. 'Positive effects' and 'no effects' equaled. The most frequently reported 'positive effects' were body temperature, shivering, and acid-base balance. No effects were more likely to be heart rate, blood pressure, and hemodynamics. Conclusion: Many types of warming therapy, are reported in the literature with little information about the efficacy of each, many different dependant variables were studied. There were no consistent reports as to length of time used for warming procedures. Overall, the effects of warming therapy are inconsistent. And additional research must be down before any particular method of warming can be used with confidence as to its effectiveness. Attention must be made as to the research design, better measurement of the dependent variables. This review may serve as a base.

  • This is the basic study on the extraction characteristics of Omija (Schizandra chinensis) for juices of Korean traditional foods. Extraction is being performed as 25 times of the solvent ratio at room temperature and at $65^{\circ}C$ with deionized water, tap water and Cheong-song mineral water which have high contents of Ca and Mg. The overall good results of the extraction conditions are calculated from the values of L (Lightness), redness (a), yellowness (b), soluble solids content, acidity, pH levels and the DPPH radical scavenging activity by using the electron donating ability (EDA). The results are as follows: 12 hours of room temperature and 6 hours at $65^{\circ}C$ were good extraction times. The Cheong-song mineral water at $65^{\circ}C$ is available for rapid extractions when compared to deionized water and tap water. A longer extraction time shows lower values of acidity but increasing values of soluble solids content and DPPH radical scavenging activity when using the electron donating ability. The best sequences for the extractions are Cheong-song mineral water followed by tap water and distilled water after overall consideration.

  • The purpose of this study was to investigate the change in blood velocity(mm/sec) when compression and/or heat were applied to the knee joint for the elderly who has both normal and painful legs with osteoarthritis(OA). Experimental compression knee band was prepared from the 3D knee data of the average women in 60's. 3D replica of knee was reduced by 7, 10, and 13% from the nude pattern in course direction. Clothing pressure was measured at the front and back of each healthy and painful knee of elderly women for one minute while standing and sitting on the chair. Blood velocity was measured at 13 cm upper from the mid-patella for 15 minutes. Results are as follows: first, compression or heating treatment itself did not change blood velocity of both legs; second, combination treatment with heating and compression was effective to increase blood velocity. In details, for healthy legs, combination treatments with compression by 10% reduced pattern(about 1.3kPa) and heating($43^{\circ}C$) induced the maximal blood velocity, however, for knees with OA, 7% reduced pattern(about 1.0kPa) with simultaneous heating($43^{\circ}C$) was more effective than other cases. These results indicated that pain and spasticity of knee joint with OA could be reduced by applying heat and compression therapy, where the compression level of painful knee should be slightly lower than of healthy leg.
