임준택,권병선 順天大學校 1997 論文集 Vol.16 No.1

냉수관개에 의한 수도생육 및 수량의 감소정도를 구명하기 위해 실시한 연구의 결과는 다음과 같다. 1) 냉수답과 온수답에서의 분얼수의 차이는 생육초기에는 커서 냉수답에서 평균적으로 35%정도의 감소를 보였으나 생육후기로 갈수록 차이가 없었고 오히려 냉수답에서 많은 분얼수를 보였다. 2) 냉수처리에 의한 초장은 생육초기에는 차이가 없었으나 생육중반에는 그 감소정도가 26%로 높았고 생육후기로 갈수록 낮아졌는데 그 크기는 19%정도였다. 3) 수온처리에 따라 고사엽수는 발생하지 않았고 생육초기에 적고정도에서 차이를 보였으나 그 정도는 미미한 정도였다. 4) 냉수답에서의 출수는 온수답에 비하여 대략 1주일정도 지연되었다. 5) 수확시 냉수답에서 평균 74.2㎝의 간장을 보여 온수답의 78.1㎝에 비해 약 5%의 단축을 보였다. 6) 냉수답과 온수답은 수장에서 각각 17.3과 19.2㎝를 보여 냉수에 의한 수장단축율은 12.2%였다. 7) 냉수답과 온수답은 주당수수에서 각각 17.2와 15.9개를 보여 냉수처리에 따라 주당수수는 오히려 증가하는 경향이었다. 8) 수당 영화수는 냉수답과 온수답이 각각 67.6개와 82.2개를 보여 냉수에 의한 수당 영화수의 감소율은 17.8%이었다. 9) 냉수답의 등숙율은 평균 72.2%로 온수답의 등숙율 78.1%보다 5.9% 낮은 경이었다. 10) 냉수답의 정조수량은 평균 545.2㎏/10a로 온수답의 평균 713.5㎏/10a보다 168.2㎏/10a정도 낮은 수준이었으며 냉수에 의한 수량감소가 적은 품종은 동진벼나 만금벼이었다. 냉수에 의한 수량감소는 간장의 감소와 등숙율의 감소에서 기인한다 할 수 있었다. This study was conducted to determine the effects of irrigating cold water on the growth and yield of rice. Rice plants were grown by irrigating water with two different temperatures, that is, irrigating cold water and warm water. In the condition of irrigation cold water, water from lake Sangsa of temperature from 11 to 20℃ was irrigated directly. In irrigating warm water, the same source of water but with 5-10℃ higher in water temperature was irrigated. Water temperature was increased by storing the water for several hours in a pond with a size of 14m in width, 25m in length and 30cm in depth. Rice plants were transplanted on June 15, and plant height and number of tillers per hill were measured nine times with the interval of 7 days from June 30. Heading date, and culm length, panicle length, yield and yield components were observed at harvest date. Water temperatures were monitored automatically at a interval of 1 hour from June 30 to Sept. 28. The results were summarized as follows. Number of tillers per hill appeared to be more than 30% lower in cold water treatment at the growing period up to July 14, but at the later growth stage, cold water treatment showed slightly higher value of number of tillers per hill compared with warm water treatment. There was no significant difference in plant height between treatments at the sampling date of June 30. From the sampling date of July 7, plant hight significantly decreased up to by 26%, but at the last sampling date of Aug. 25, the difference became smaller by 19%, compared with that of warm water treatment. The heading date of cold water treatment delayed about 7 days. Culm and panicle length in cold water treatment decreased 5% and 12.2%, respectively, compared with warm water treatment. Number of panicles per hill were 17.2 in cold water treatment and 15.9 in warm water treatment, so that cold water treatment showed higher value in number of panicles than that of warm water treatment. Number of spikelets per panicle in cold and warm water treatment were 67.6 and 82.2, respectively, so that cold water treatment showed 17.8% lower value in number of spikelets compared with warm water treatment. Percent of filled spikelets in cold water treatment was 72.2%, which was 5.9% lower than 78.1% of warm water treatment. Rough rice yield in cold water treatment were 545.2㎏/10a in average, which was 168.2㎏/10a lower than 713.5㎏/10a of warm water treatment. Decrease in yield under cold water irrigation mainly appeared to come from the decrease in culm length and percentage of filled spikelets.

Algal bioassay 에 의한 조류생장 제한영양염류 결정

Determination of Limiting Nutrient for Algal Growth by Algal Bioassay. Oh, Hee-Mock, Seog June Lee, Seong-Bin Kim, Mi- Kyung Park, Byung-Dae Yoon and Do-Han Kim (Environmental Microbiology Research Unit, Korea Research Institute of Bioscience and Biotechnology, Taejon 305-333, Korea and Water Resources Research Institute, Korea Water Resources Corporation, Taejon 305-390, Korea) Water quaiity and algal growth potential (AGP) using Microcystis aeruginosa were investigated from April to September 1997 in Daechung Reservoir. Secchi disk transparency was 1.1 m in August. Chlorophyll-a concentrations were higher than 10㎍/l at all samples. Total phosphorus concentration was in a range of 0.020∼0.027mg/l which is at the approximate value of 0.03 mg/l, the general critical level of eutrophication. These results indicate that Daechung Reservoir is in an eutrophic state except some temporary times and restricted sites. Phosphorus uptake rate of M. aeruginosa was higher in the water from the epilimnion than in the hypolimnion and also higher under light condition than under dark condition. Therefore, phosphorus uptake rate appears to depend on cellular phosphorous content and light condition, a meaning of endergonic process. Phosphorus was the most frequently limiting nutrient: phosphorus was limiting algal gowth in April and May, nitrogen, phosphorus and trace elements were the limiting factors for algae in August, and trace elements in September. If a fast growing alga, M, aeruginosa, is used as a test organism for assaying AGP, in vivo fluorescence instead of dry weight can be measured for algal biomass and incubation period can be reduced from traditional 14 days to 7 days.

박병희,장경준,신지용 大韓神經精神醫學會 1996 신경정신의학 Vol.35 No.3

본 연구는 Rest가 고안하고 문용린이 번안한 주제정의검사(DIT)를 사용하여 청소년기의 도덕발달수준을 알아보고 비행청소년의 도덕발달수준과 비교하여 그 차이점에 대해 알아보고자 하였다. 먼저 신지용 등(1995)이 정상 고교생군에 대해 조사하였고 본 논문에서는 비행청소년군의 조사와 두 군의 비교 분석을 통해 청소년기의 도덕발달수준과 관련된 변인의 유의성을 검증하였다. 연구대상은 정상 고교생군 254명과 비행청소년군 285명이었다. 설문지 작성시 문항에 대한 이해 부족으로 생기는 오차를 줄이기 위하여 자세한 설명과 연습을 실시하였고 충분한 시간이 주어지도록 하였다. 수집된 자료는 컴퓨터로 채점되었으며 정상군의 자료와 함께 분석되었다. 연구의 결과는 다음과 같이 요약할 수 있다. 1) 정상 고교생군에 비해 비행청소년군은 도덕발달수준이 유의하게 낮게 나타났다(p<0.05). 2) 비행청소년군의 경우 종교에 따라 도덕발달수준의 유의한 차이를 보였으며 이는 천주교와 불교간의 수준차이로 검증되었다. 3) 정상고교생군과 비행청소년군의 PM점수 차이의 상관관계 분석 결과 아버지, 어머니의 교육수준 요인에서 주효과가 유의하게 나타났으며 주성장지는 상호작용 효과에 유의한 것으로 나타났다. Objectives : This study was directed to compare the moral developmental levels between normal and delinquent adolescent groups. And the authors also intended to find the demographic variables that influence the differences of moral levels between two groups. Methods : Defining Issue Test questionnaires were applied to 285 delinquent adolescents and the data were compared and analyzed with the normal control data of previous Shin's study(1995). Results : 1) The PM scores(scores of principled morality) of delinquent group(28.6±15.01) was significantly lower than that of normal control group, 41.8±15.10(p<0.05). 2) The PM scores were not significantly different according to the age in delinquent adolescents. 3) The PM scores were significantly different according to the religious varible, especially between Catholic and Buddhism in the delinquent adolescents. The Catholic group recorded the highest and Buddhism, the lowest. 4) Comparing the scores between normal and delinquent adolescents, there were significant differences according to the educational of mother and father, and the birth places. Conclusion : The moral developmental process of adolescents requires the proper education from parents, school, religion or other social environment. The corrective reexperience of normal developmental steps are needed especially to the delinquent adolescents.

Objectives : We report an interim result of conformal radiotherapy in a patient with early stage cancer at the base of the tongue, which developed in a previously irradiated area. Materials and Methods : A 64-year-old male patient was diagnosed with T4NOMO supraglottic cancer. He received 72Gy of radiation therapy from 21 November 1988 to 24 February 1989. He had local failure and underwent a salvage total laryngectomy on 28 August 1989. Subsequently, he did well. In early 1999, he suffered from throat pain. He had a 2.5cm ulcerative mass at the base of his tongue, in the area that had been irradiated previously. Biopsy showed squamous cell carcinoma. After workup, he was diagnosed with base of tongue cancer with T2NOMO. Surgery was not feasible because the morbidity was not acceptable. Since it was difficult to re-irradiate the area with a curable dose using conventional 2D radiation therapy with an acceptable morbidity, we decided to try conformal radiotherapy. We used 7 static beam ports with field sizes from 7×6.4 to 8×8㎠, using 6 and 10MV photons. The fractionation regimen was 1.8Gy, 5 times per week. He received 64.8Gy in 36 fractions from 9 April 1999 to 1 June 1999. Results : In the 21 months since radiotherapy, the patient has not experienced any acute or chronic complications, such as xerostomia. He experienced relief of pain shortly after the start of radiotherapy, showed a complete response, and is still doing well. Conclusion : Conformal radiotherapy can be used to treat cancer that develops within a previously irradiated field, with curative intent.

위암에 의한 간 전이의 CT 진단에 있어 조영제의 급속 정맥주사방법을 이용한 문맥기 역동적 CT의 유용성 : Usefulness of Bolus Dynamic CT During Portal Phase

조준식,송창준,김종철,이병철 충남대학교 의과대학 지역사회의학연구소 1994 충남의대잡지 Vol.21 No.2

Purpose : We evaluated the usefulness of dynamic CT during portal phase with faster injection rate of contrast material in detecting hepatic metastases from gastric cancers. Subjects and Methods : We retrospectively analyzed two-phase dynamic CT findings (portal phase and equilibrium phase) in 17 patients with pathologically proven gastric cancers and hepatic metastases. In 13 patients, a total of 150ml of nonionic contrast material was administered with a power injector at a flow rate of 5ml/sec for 30 sec, and two-phase images were obtained at 45-70 sec (portal phase) and 2-4 min (equilibrium phase) after the start of bolus injection. In four patients, two-phase dynamic CT with spiral technique was performed with the same method. Results : In cases of metastases less than 1 cm in diameter, 65 lesions were detected in the portal phase that showed clearly defined hypodense lesions in highly enhanced hepatic parenchyma. Whereas, only nine (14%) lesions were detected in the equilibrium phase and the remaining 56(86%) lesions showed isoattenuation. In cases of metastases more than 1 cm in diameter, 37 lesions were detected in the portal phase that showed clearly defined hypoattenuations. whereas, the images of equilibrium phase showed isoattenuation in five (14%), mixed attenuation in three (8%), and hypoattenuation in 29 (78%). The lesions detected in the equilibrium phase showed poorly defined hypodense lesions and tended to decrease in size due to peripheral enhancement of lesions. Conclusion : Dynamic CT during portal phase with faster injection rate of IV contrast material is an useful technique in detecting hepatic metastases from gastric cancers, particularly small lesions less than 1 cm in diameter.

韓國工業의 成長率分析

黃炳晙 서울大學校商科大學 韓國經濟硏究所 1965 經濟論集 Vol.4 No.3

Ⅰ.The Growth antral Structure of Korean Economy This thesis aims to analyse the growth rate of Korean manufacturing industry It is necessary, however, that we look into the growth rate and structure of national economy of this country before we examine the essential points. The first chapter of this thesis is consisted of the following three sections: 1. Trend of Economic Growth Rate The rate and trend of Korean economic growth in the past 16 years (1948-64) were analysed here. As you see In Table 1 Korean economy was doubled in scale during this period, and its average economic growth rate per year showed 5.5%. In details. an average growth rate of secondary industry was increased by 14.9% per year. This growth rate of 14.9% is much higher than those of any other industries. On the contrary, primary industry showed the lowest average growth rate of 3.3% per year(see Table 1). Actually, during the past 20 years of 1945-64, we had had a series of social and political insecurities including the Korean War which lasted three years, and the two political revolutions. As a result, it can be easily understood that the growth of Korean economy in this period could not show a favorable upward trend, and its fluctuations were pretty remarkable. 2. Changes of the Industrial Structure During the same period, the different growth rate by industry has brought about a considerable changed of the industrial structure. In Table 5 we can see that the proportions of primary, secondary and tertiary industrials to GNP consisted of 46.3%,8.6% and 45.1%, 8.6% and 45.1% in 1948 but those are changed into 31.4%, 22.4%, and 46.2% in 1964. So to speak, as the result of rapid growth in the secondary industry including mining, manufacturing and electric power, the notable improvement of the industrial structure has been realized. This means in brief the industrialization of Korean economy. Now, focusing our attentions on manufacturing industry, we can point out in Table 6 that its average growth rate par year during 1953-64 amounted to 10.9% twice as high as that of the whole economy. Consequently the proportion of manufacturing industry to GNP was increased from 8.0% in 1953 to 14.3% in 1964 (see Table 7 and 16), and so five dare to say that Korean economy has been strikingly industrialized during the past 10 years. 3. Direction and Problems for the Improvement of Industrial Structure In spite of such an outstanding improvement of the industrial structure, still the proportion of primary industry including agriculture. forestry and fishery to GNP occupies 31.4%. in 1964 while that of tertiary industry indicates 46.2% in the same year. This means that the structure of Korean industry has not yet emerged out of its traditional backwardness and deformity, Under such a present condition it would be unreasonable and more almost impossible to convert at one time the present industrial structure into a developed country's model which shows the order of the weight to GNP to be tertiary industry. secondary industry and then primary industry. Therefore, I would like to say the reasonability should be insisted that for the time being the readjustment of the industrial structure in Korea will be made on the basis of such an order as the proportion of primary industry to GNP is highest and that of a secondary industry lowest. Ⅱ An Analysis on the Growth Rate and its Trend of Korean Manufacturing Industry. This part is the core of this analysis. I carried out an analysis on the growth rate before 1945, and the trend of Korean manufacturing industry for the period from the liberation of 1945 to 1964, and also for the long period under the Japanese rule before. It is because that Korean manufacturing industry of nowadays is closely related to the structural deformity inherited by Japanese imperialistic rule over this country. Hence, the growth rate and its trend of manufacturing industry were figured out and examined as follow: (1) for the period about 20 years before the liberation of 1945, (2) for the period since the liberation, particularly from the truce of Korean War in 1953 to 1964, and (3) for the near a half of a century throughout the above two periods. The analysis on the above three stages is chiefly based on a series of tables as shown in the body of this thesis. And also, at the end of this part. some notes on the industrialization of Korean economy, which has been brought about as the result of rapid growth of manufacturing industry, were added. Lastly we observed that the annual average growth rate of Korean manufacturing industry from the truce of Korean War in 1953 to 1964 was far lower than that of the industry in 1930s when Korea had been ruled by Japan and was as similarly high as in 1920s and that the Proportion of manufacturing industry to GNP which shows the industrialization of national economy almost corresponds to that in 1920s.

공기공급방식별 계분 퇴비화의 분해율 비교에 관한 연구

金丙泰,安俊帥,朴泰術 대진대학교 1994 大眞論叢 Vol.2 No.-

Composting has had little practical use in solid wastes disposal until now because of a lack of understanding of process control. Ventilation control was reported to be convenient to operate and maintain good product quality during composting. This study was carried out to compare the degration rate and evaluate optimum temperature for composting of poultry manure by the aeration method. Substrate losses were investigated by the degradation rate of total, dry, volatile matter, carbohydrates, lipids and proteins. The optimum temperature for composting of poultry manure was estimated by the CO₂ production rate and O₂consumption rate. The period of initial heating stage, thermophilic stage and transition stage in the temperature feedback aeration method was longer 2days than that of constant aeration method The degradation rate in the temperature feedback aeration method was higher than that in the constant aeration method The degadation rate in both aeration methods peaked in the thermophilic region. Dry matter was degraded about 58~59% until the thermophilic region. The variation of gas exchange was similar to that of temperature On the basis of the recommened range of CO₂ production rate and O₂ consumption rate, the optimum temperature range for composting of poultry manure appears to be below 60℃.
