The yield of dry matter and total nitrogen content of forage crops which were sown grown alone and in mixture with orchardgrass and legumes such as alfalfa, red clover, birdsfoot trefoil were studied using nitrogen fertilization and inoculation, and the results are as follows; 1) With-nitrogen for the yield of dry matter of forage crops was highly effective only to orchardgrass and was also effective to the early stages of alfalfa and birdsfoot trefoil in case of a mixed sowing. 2) In accordance with inoculation, the yield of dry matter of forage legumes on without-nitrogen increased as compared with that of orchardgrass. 3) Alone and mixed sowings showed the yield of dry matter and total nitrogen content in a decreasing order of alfalfa>red clover>orchardgrass>birdsfoot trefoil, and orchardgrass+alfalfa>orchardgrass+red clover>orchardgrass+birdsfoot trefoil, respectively. 4) The total nitrogen content and yield of dry matter revealed a positive correlation, and nitrogen was found to be a major factor for the dry matter productivity.

치과용 도구세척을 위한 화학용액을 개발하기 위하여, 상용 치과재료용 화학용액의 주성분을 바탕으로 분해성능에 영향을 미치는 성분, 조성, 조건에 대한 연구를 수행하였다. 분해성능은 온도가 높을수록, 초음파의 세기가 클수록 향상되었다. 화학용액에 첨가된 계면활성제는 분해를 촉진시켰으며 계면활성제의 종류에 따라 부내성능에 큰 차이를 보였다. 알콜류는 분해성능을 저하시키는 나타났으며 시멘트류는 NaOHtndyddor에, 석고류는 sodium bicarbonate 수용액에서 뛰어난 분해성능을 보였다. Chemical solutions were prepared and the effects of chemical composition of decomposition ability of cleaning solution for dental instruments were studied. With high temperature and ultrasonic intensity, decomposition ability of cleaning solution were improved. Certain surfactants(Miwon Commercial Co. Ltd) such as amine oxides and alkanol amides accelerated decomposition rate of cleaning solution. Alcohols added to solution made worse the decomposition capability of cleaning solution. Dental cements and gypsums were well decomposed in sodium hydroxide aqueous solution and sodium bicarbonate aqueous solution respectively.

Objectives : We evaluated the efficacy of ramosetron and ondansetron for preventing postoperative nausea and vomiting (PONV) in laparoscopic colectomy. Methods and Materials : Eighty patients who received laparoscopic colectomy were randomly divided into two groups: R group (ramosetron 0.1mg PO) and O group (ondansetron 4mg twice IV). Injection or oral medication was administered before the induction of anesthesia in each group. Injection was administered at the end of surgery in O group. General anesthesia was induced using propofol and rocuronium, and maintained with sevoflurane, remifentanil and air (FiO2 0.5), We investigated the incidences of PONV in each group by the Rhodes index of nausea, vomiting and retching (RINVR) at postoperative 6 and 24 hours. Results : The incidence of PONV was not different between group at each time points after surgery (at postoperative 6 hours: 20% in group R, 17.5% in group 0, at postoperative 24 hours; 12.5% in group R, 7.5% in group 0). There was no difference in the severity of PONV, satisfaction, rescue drug usage. Conclusion : Prophylactic therapy with ramosetron is as effective as conventional prophylactic therapy with ondansetron for preventing PONV in general anesthesia for laparoscopic colectomy.

Recently, the humidity adjustment of indoor air is of great importance in air conditioning system as a applied, in buildings, vehicles, and containers for storage and transport of perishable products. Membrane dehumidification or air is potentially attractive because it offers low capital and operating costs, along with low energy consumption. And membrane dehumidification process attracted the attention of the public instead of the other dehumidification processes, such as adsorption, absorption, and refrigeration cycles and so on. In this study, the prepared hydrophilic inorganic membrane-based dehumidifiers (membrane air dehumidification) examined the performance of dehumidification. The surface-modified inorganic membrane prepared in this study showed high dehumidification efficiency (over 80%). Thc membrane might be very useful for dehumidification industries.

폴리설폰 중공사막에 대한 산소/질소 혼합물의 분리

국내 K-그룹 연구소에서 제조한 폴리설폰 중공사막의 산소/질소 혼합물에 대한 압력, stage cut, 공급기체 혼합물의 조성에 따른 분리성능을 조사하였다. 본 실험의 압력범위와 온도 30℃에서의 이상분리인자(O₂/N₂)는 5.7이었으며, 유입기체 혼합물의 21 mole% 산소농도가 약 50 mole%로 농축되었다. 저압츠과 고압측의 압력비는 산소농축에 미치는 영향이 적었으며, 이상분리인자의 영향은 매우 컸다. 그러나, 이상분리인자가 증가함에 따라 이상분리인자의 영향은 둔화되었다. 따라서, 이상분리인자가 큰 신소재 개발과 더불어 공정변수의 최저화가 필요하다. 수학적 모델링에 의한 예측치와 실험치가 잘 맞았다. The performance of the polysulfone hollow-fiber membrane manufactured by K-group Research Institute in Korea was investigated for the separation of O₂/N₂mixture as a function of pressure, stage cut, and feed gas composition. The ideal separation factor(O₂/N₂) at temperature 30℃ was around 5.7 in the pressure ranges studied. Oxygen concentration of 21 mole% in feed stream was concentrated to about 50%. Although the pressure ratio between high and low pressure side showed little effect, ideal separation factor showed greater effect on the oxygen enrichment. However, the effect was declined with increase in the ideal separation factor. Therefroe, the optimization of process variable is necessary as well as development of new material with high ideal separation factor. It was fond that experimental data were well correlated with the prediction of mathematical model.

Among the various plant and flower characteristics, the length of style and filaments was particularly different in Forsythia Koreana (short style and long filaments) and Forsythia ovata (long style and short filaments). Forsythia Koreana exhibited strong self-and-cross-incompatibility with F. ovata, whereas F. ovata showed little or no such incompatibility. Seeds germinated readily thus showing no apparent dormancy. Seed sterilization with sodium hypochlorite or low temperature storage of imbibed seeds significantly increased germination rate. Compact Forsythia seedlings responded better to exogenous GA_(3). Stem and branch length was markedly increased by GA_(3) spray. Combined spray of TIBA and BA was most effective in increasing branch numbers in decapitated Forsythia ovata seedlings.
