안길환,박병순 선문대학교 자연과학대학 1998 자연과학대학 논문집 Vol.1 No.-

마이토콘드리아의 돌연변이는 Phaffia rhodozyma에서 carotenoid의 생산을 증대시켰다. 마이토콘드리아의 호흡 돌연변이는 acriflavine과 ethidium bromide를 이용하여 유도되었다. 총 9개의 시험된 호흡 돌연변이주 중 7개가 모 균주에 비하여 증대된 carotenoid를 생산하였다. 호홉 돌연변이주에서 활성산소의 생산이 증대되고 이것이 carotenoid의 생산을 증대시킨 것으로 사료된다. Mitochondrial mutation increased carotenoid production in Phaffia rhodozyma. Mitochondrial petite mutants were selected after treatment with acriflavine and ethidium bromide. Seven out of nine petite mutants, tested, produced increased carotenoid compared to their parent strain. Increased reactive oxygen species might be produced in the petite mutants, and this caused carotenoid production.

The limnological survey of Lake Okjong was conducted for one year from June 1993 to May 1994 on the monthly basis. The loading of phosphorus, nitrogen and organic carbon from the watershed into the lake were monitored at the main in flowing sites. Secchi disc transparency , epilimnetic chlorophyll a, total nitrogen, total phosphorus concentration and primary production were in the range of 1.3~4.H m, 2.4~ 18.7 mg Chl/m³. 1.25~2.87 mg N/l, 7~65 mg P/m³, 325~2,113 mg C/m²/day, respectively. TN/Tl atomic ratio varled from 129 to 443. N/P ratio decreased in summer because phosphorus concentration was higher than in winter, while nitrogen did not vary much. The seasonal succession of phytoplankton was distinct. In winter and spring, diatoms, Aulacoseira granulata var. angustissima and Aulacoseira italica were dominant while cyanobacteria, Microcystis sp.,M. ichthyovlabe, Phormidium sp. and P.valderianum var. tenuis were dominant in warm seasons. The dominant zooplankton species were Thertmocyclops taihokuensis in warm seasons while Boosmina longirostris were dominant in cold seasons. The organic carbon, nirtogen and phosphorus content of lake sediment were 8.0~14.8, 0.59~0.71, 1.14~1.87 ng N/g, respectively. The sediment of Lake Okjong can be classified as oligohumic based on C/N ratio. The total phosphorus loading from the watershed and fishfarm were estimated to be 2.7g P/m²/yr, which far exceeded the critical loading for eutrophication. The organic carbon loading from the watershed and primary production were determined to be 998t C/yr, 6,348t C/yr, respectively. Most of organic carbon was contributed by autochthonous primary production of phytoplankton. Trophic state of Lake Okjong can be classified as eutrophic

This study was conducted to investigate the changes of physico-chemical properties of soil applied with compost made by food wastes and its effect on the growth and yield of Chinese cabbage. Chinese cabbage was grown in the soil treated with food waste compst(FWC) of 0, 0.625, 1.25, 2.5, 5 and 10㎏/3.3㎡. As the amount of FWC increased, number of leaves, leaf area and fresh weight increased where application of 5㎏ and 10㎏/3.3㎡ showed vigorous plant growth in the late growing period. The pH of soil by application of FWC was not raised, which was similar to the soil before treatment. Organic matter increased in soil by increasing the amount of FWC. However, concentration of Cu and Pb in the soil reduced. The concentration of available phosphate(P) was lower in the soil treated with FWC than in the soil before treatment, which means that a large amount of P may be uptaken by plant. This study suggested that FWC should be an alternative to chemical fertilizer for vegetable production.

In this study limnological characteristics of Lake Juam was surveyed from June 1993 to May 1994 in order to provides important information regarding water resources. Seschi disc transparency, epilimnetic chlorophyll a(chl-a), tatal nitrogen(TN), total phosphorus(TP) concentration and primary productivity were in the range of 2.0~4.5 m, 0.9~13.6 mgChl/㎥, 0.78~2.32N/l, 11~56 mgP/㎥, 270~2,160mgCm^(-2)day^(-1), respectively. On the basis of TP, Chl-a and Secchi disc depth, the trophic state of Lake Juam can be classified as mesotrophic lake. The phosphorus inputs from non-point sources are concentrated in heavy rain episodes during the monsoon season. As a result, phosphorus concentration are higher in summer than in winter. TP loading from the watershed were estimated to be 0.9 gPm^(-2)yr(-1), which correspond to a boundary of the critical loading (1.0 gPm^(-2)yr(-1), which correspond to a boundary of the critical loading (1.0 gPm^(-2)yr(-1)) for eutrophication. From the results of the algal assay, both phosphous and nitrogen act as limiting nutrients in algal growth. The seasonal succession of phytoplankton community structure in Lake Juam was similar to that observed in other temperate lakes. Diatoms(Asterionella formosa and Aulacoseira granulata var. angustissima) were dominant in spring and winter, cyanobacteria (Microcystis aeruginosa, M. sp. and M. viridis) were dominant in warm season. The organic carbon, nitrogen and phosphorus content of lake sediment were 9.5~14.0 mgC/g, 1.01~1.82 mgN/g, and 0.51~0.65 mgP/g, respectively. The allochthonous organic carbon loading from the watershed and autochthonous organic carbon loading by primary production of phytoplankton were determined to be 1,122 tC/yr and 6,718 tC/yr, respectively. To prevent eutrophication of Lake Juam, nutrient management of watershed should be focus on reduction of fertilizer application, proper treatment of manure, and conservation of topsoil as well as point source.

본 연구는 정보교육 프로그램이 갑상샘암 수술 환자의 심리 및 신체적 불편감 감소에 미치는 효과를 검정하기 위해 실시된 비동등성 대조군 전,후 시차 설계의 유사 실험연구이다. 자료수집 기간은 2006년 6월 17일 부터 9월 19일 까지 3개월간 이었으며, 연구 대상자는 일개 종합병원에 갑상샘암 수술을 받기위해 입원한 환자 가운데 6월 17일 부터 8월 3일 까지 입원환자 29명을 대조군으로 하였고, 8월 5일 부터 9월 19일 까지 입원환자 30명을 실험군으로 하였다. 연구도구는 심리적 불편감을 측정하기 위해 Derogatis 등(14)이 개발한 ‘자기보고식 다차원 증상목록(Multidimensional Symptom Inven- tory)검사를 사용하였고, 신체적 불편감 측정은 McCorkle & Young(16)이 개발한 도구를 사용하였다. 본 연구의 결과는 다음과 같다; 1) 정보교육 프로그램을 받은 실험군은 정보교육 프로그램을 받지 않은 대조군에 비해 심리적 불편감 정도의 차이는 통계적으로 유의한 차이를 보이지 않았다(p= .135). 다만 ‘근심 걱정’요인에서 유의한 불편감 감소효과를 보였다(p= 0.49) . 2) 정보교육 프로그램을 받은 실험군과 정보교육 프로그램을 받지 않은 대조군은 두군 모두 신체적 불편감 정도가 사후 유의한 수준으로 증가함을 보였다(p= 0.90). 결론적으로 본 연구를 위해 만들어진 정보교육 프로그램은 갑상샘암 수술 환자의 신체적 불편감 감소에는 효과적이지 못하였으나 심리적 불편감의 근심걱정 요인을 감소시키는데는 효과가 있음을 알게 되었다. Objectives: This study was designed as a non-equivalent control group pre and post-test quasi-experimental study to examine the effects of education program using information on the psychological and physical discomfort of patients undergoing operation for cancerous thyroid glands. Methods: The study covered for three months from June 17, 2006 to September 19, 2006. The subjects of this study were selected from those patients who were admitted in one of the general hospitals in order to receive the operation for cancerous thyroid glands. They include 29 control group patients who were hospitalized during the period of Jun 17th to August 3rd 2006, and 31 experimental group patients who were hospitalized during the period of August 5th to September 19th, 2006, respectively. The instruments utilized for conducting this study includes the Multidimensional Self-Report Symptom Inventory test originally developed by Derogatis & et al. (1983) for measuring psychological discomfort. And for measuring physical discomfort, the tools developed by McCorkle & Young (1978) was utilized. Results: 1) Hypothesis 1 “The level of psychological discomfort of the experimental group who completed the information education program would be decreased comparing with that of the control group who didn't complete the program” was partly supported (Worry & Anxiety factor: p= .049). 2) Hypothesis 2 “The level of physical discomfort of the experimental group who completed the information education program would be reduced comparing with that of the control group who didn't complete the program” was not supported (p= -.90). Conclusion: The information program provided for this study was proved to be not effective for decrease physical discomfort of the patients undergoing operations for cancerous thyroid glands but proved to be effective for decrease the anxiety factor of psychological discomfort.

경남지역과 충북지역 감나무의 재배, 해충 방제실태를 농가 방문하여 설문조사 한 결과 감 재배경력은 경남지역이 평균 10년이며, 충북지역은 평균 5년 정도이다. 감 재배 주수는 대다수 농가가 20주 이상이고, 재배관리에 대하여 자문을 받는 곳은 농업센터나 농약사 및 연구소 등이었다. 김 품종은 경남지역에서는 부유와 서촌조생, 충북지역에서는 등시와 월하 등을 재배하고 있었다. 시비종류는 이른봄 에 퇴비나 복합비료를 주었고, 감나무 생장 중 열매나 저장 중 열매에 발생하는 해충이 발견되었다. 해충방제를 위해 살충제를 살포하고 있는데 주로 감꼭지나방, 진딧물, 잎말이나방 및 깍지벌레 등으로 파마치온, 파단, 코니도, 신파마치온, 수프라사이드 등을 살포하였다. 감꼭지나방(Stathmopoda masinissa)의 발육생태를 조사하기 위하여, 감꼭지나방을 야외에서 채집하여 온도±1℃, 광주기 16L:8D, 상대습도 50~60%에서 실내 사육하였다. 각 층태별 기간은 알 7.4일, 유충기간 34.7일, 용 15.5일이었다. 각 령기간은 1령 3.5일, 2령 4.2일, 3령 5.2일, 4령 6.5일, 5령 15.4일이었으며, 특히 유층의 두폭을 측정하여 평균한 결과는 1령 0.20mm, 2령 0.40mm, 3령 0.65mm, 4령 0.87mm, 5령 1.07mm일 이었다. 성충의 수명은 수컷이 6.2일, 암컷이 10.1일 이었다. 용화율은 68.0% 우화율은 59.9%이었다. A survey in Kyungnam and chungbuk areas revealed that the average number of years for persimmon tree farming is 10 and 5 years, respectively. The number of trees per orchard is at least over 20, and the farmers have been usually advised through an agricultural center, an agrochemical store, or agrochemical research center. The varieties of the persimmons they grow are Buyu and Seocheon in Kyungnam, and Doogsi and Wolha in Chungbuk. The kind of fertilizers they sprayed in early spring is either compost or composite fertilizer. persimmon pests are often found in persimmon fruits while on a tree or in storage. Phamathion, Padan, Konido, Sinpamathion, and/or supuraside is usually used to control persimmon fruit moths, aphides, leafrollers, and scale insects. To understand the developmental ecology of the persimmon fruit moth, Stathmopoda masinissa Meyrick, we collected and reared them under the laboratory condition which is at 25±1℃ of temperature, 16L:8D of photoperiod, and 85% of relative humidity. As a result, the developmental period of egg, larva, and pupa were 7.40, 34.7, and 15.5 days, respectively. The average period of each larval instar was 3.50, 4.17, 5.17, 6.46, and 15.42 days, respectively, and the average head capsule width was 0.20, 0.40, 0.65, 0.87, and 1.07mm, respectively. The average adult longevity was 6.2 days for males and 10.1 days for females. The pupation rate and the emergence rate were 68.0% and 59.9%, respectively.
