박우철,이상갑 한국콩연구회 1989 韓國콩硏究會誌 Vol.6 No.1

식물 생장조절제에 의한 녹두의 부위별 peroxidase, catalase 활성과 전기영동상 peroxidase 등위효소의 변화를 조사하였다. 녹두의 생육이 진행됨에 따라 하배측을 제외하고는 peroxidase 활성도는 증가하였으나 catalase 활성도는 감소하여 서로 상반된 결과를 나타내었다. 암발아시킨 녹두에 GA₃와 ABA를 각각 처리하면 peroxidase 활성도의 증가에 대하여 자엽에서만 GA₃가 ABA 보다 더 큰 영향을 끼쳤으나 catalase 활성도 변화는 ABA가 GA₃ 보다 더 큰 영향을 끼쳐 모든 부위에서 활성도를 증가시켰다. GA₃와 ABA를 혼합하여 처리하면 효소 활성도의 변화 경향은 GA₃보다 ABA에 더 큰 영향을 받았다. Peroxidase 등위효소의 수는 발아, 생육이 진행됨에 따라 모든 부위에서 계속 증가하여 활성도와는 무관하게 발아 후 6일째에 가장 많이 나타났으며, 호르몬의 처리에 따른 동위효소의 변화는 동위효소의 수에 대해서 보다는 intensity에 대하여 더 큰 영향을 받은 것으로 나타났다.

박우철,서인호,김신혜,이용제,안성복 대한가정의학회 2017 Korean Journal of Family Medicine Vol.38 No.1

Background: Inflammation is an important underlying mechanism in the pathogenesis of atherosclerosis, and an elevated resting heart rate underlies the process of atherosclerotic plaque formation. We hypothesized an associa-tion between resting heart rate and subclinical inflammation.Methods: Resting heart rate was recorded at baseline in the KoGES-ARIRANG (Korean Genome and Epidemiology Study on Atherosclerosis Risk of Rural Areas in the Korean General Population) cohort study, and was then divided into quartiles. Subclinical inflammation was measured by white blood cell count and high-sensitivity C-reactive protein. We used progressively adjusted regression models with terms for muscle mass, body fat proportion, and adiponectin in the fully adjusted models. We examined inflammatory markers as both continuous and categorical variables, using the clinical cut point of the highest quartile of white blood cell count (≥7,900/mm3) and ≥3 mg/dL for high-sensitivity C-reactive protein.Results: Participants had a mean age of 56.3±8.1 years and a mean resting heart rate of 71.4±10.7 beats/min; 39.1% were men. In a fully adjusted model, an increased resting heart rate was significantly associated with a higher white blood cell count and higher levels of high-sensitivity C-reactive protein in both continuous (P for trend <0.001) and categorical (P for trend <0.001) models.Conclusion: An increased resting heart rate is associated with a higher level of subclinical inflammation among healthy Korean people.

부부상담 임상연구에서 모델중심 성과연구와 공통요인 연구에 대한 개관

박우철 한국상담학회 2016 상담학연구 Vol.17 No.2

Couple therapy as a mode of psychotherapy has gradually developed over the decades, which was possible by virtue of the development of outcome studies examining efficacy/effectiveness of treatment models. However, due to limitations of the outcomes studies couple therapy research started to evolve into a different type of approach, namely, common factors approach, which focuses more on common change mechanisms existing across treatment models. The present study delineates the trends of couple therapy clinical research by reviewing both model-centered outcome research and pan-theoretical common factors research. Specifically, the study introduces outcome studies testing efficacy/effectiveness of developed or enhanced treatment models and reviews couple therapy models which have been empirically supported by the outcome studies. Also, the study introduces the newly arising common factors paradigm and reviews relevant common factors research. Lastly, recommendations for research and training are discussed. 부부상담은 부부관계를 향상시키는 데 있어 그 효과를 입증하며 지난 수십 년간 발전해왔다. 이러한 부부상담의 발전은 개별 부부상담모델을 개발하고 그 효과를 입증한 성과연구(outcome research)의 발전이 있었기에 가능한 것이었다. 이렇게 특정 모델의 개발과 수정에 집중하던 부부상담의 임상연구는, 최근 특정 모델을 넘어 여러 모델에 공통적으로 존재하는 변화기제에 초점을 두는 공통요인(common factors)에 대한 관심으로 이어졌다. 본 연구는 이러한 부부상담 임상연구의 발전양상을 모델중심 성과연구와 범모델적 공통요인 연구를 중심으로 개관한다. 구체적으로, 본 연구는 개별모델의 효과를 측정하는 성과연구를 소개하고 성과연구를 통해 과학적 효과를 입증한 부부상담모델들을 정리한다. 나아가 공통요인 패러다임을 소개하고 관련 연구를 소개한다. 마지막으로 본 연구는 부부상담 임상연구의 발전 동향과 국내 부부상담의 현실을 고려하여 연구, 교육/훈련에서의 미래 제언을 제시한다.

박우철,차재룡,김재현,Park, Woo-Chul,Cha, Jae-Ryong,Kim, Jae-Hyun 한국위성정보통신학회 2009 한국위성정보통신학회논문지 Vol.4 No.1

본 미래 전쟁 양상은 정보화 시대의 도래와 함께 다른 분야와 마찬가지로 전쟁수행 여건에도 많은 변화를 가져왔다. 이에 따라 정보우위와 정보전이 중요시되고 네트워크 중심전(Network Centric Warfare) 등 새로운 전쟁수행 개념이 등장하게 되었다. 군 위성통신체계는 미래 NCW 전장환경에서 전장정보의 실시간 전송이 가능하며, 전장의 광역화, 자동화, 신속화 개념을 지원하고, 광역성, 이동성, 생존성 및 융통성이 보장된 전천후 핵심전략 통신체계이다. 이러한 군 위성통신시스템은 실시간 전장정보전송을 위한 광역 대용량 링크, 생존성, 이동간 통신을 제공하는 체계로 분류된다. 본 논문에서는 이러한 기능을 통합하여 지원하는 미군의 차세대 TSAT체계의 주요 운용개념과 핵심기술을 분석하였다. 분석 결과를 바탕으로 NCW 대비한 차세대 군 위성통신체계 상위 구조는 재밍이나 간섭 등의 채널환경에 최적으로 적응하여 서비스가 가능한 전송율, 항재밍 능력, 망 제어 및 망 관리 능력을 갖추어야 하며 고속 이동 차량, 초소형단말, 초고속 무인기 등의 다양한 플랫폼을 지원해야 하는 등 향상방안을 제안하고, 또한 이러한 체계 구조를 위한 소요기술로 적응형 다중안테나, 레이저 링크, 차세대 항재밍 waveform을 제안한다 As the information age comes out, the aspect of future war brings about the many changes in terms of war-fighting environment. Accordingly, information superiority and intelligence-centric warfare have been important and new war-fighting concept such as NCW(network centric warfare) have been turned up. This paper proposed all-weather core-strategy communications systems guaranteeing not only the real-time transmission of the information collected in a battlefield and expansion, automation, and rapidity of a battlefield but also broadband, mobility, survivability, and flexibility. The proposed military satellite communications system is classified into wideband mass capacity link, survivability, and the system supporting OTM(on the move) communication for the real-time transmission of battlefield information. This paper analyzed the essential operation concepts and core schemes of the U.S. Army's next generation system, TSAT(Transformational Satellite Communication System). Base on the analysis results, this paper proposed that the architecture of next generation military satellite communications systems for NCW have to provide the data rate, anti-jamming capability, network control and management capability which are optimally adaptable for the wireless channel environments such as jamming and interference and to support the variety of platforms like high-speed mobile vehicles, micromini devices, super-high speed unmanned aerial vehicles. Finally, this paper also proposed that next generation military satellite communications systems need the technologies such as the adaptable multi-antenna, laser link, and next-generation anti-jamming waveform.

Experiments were carried out to clarify the effects of NPK content of fertilizers on the development of leaves out of new bulblets, and to investigate the relationship between the state of fleshness of a new bulblet and the weight and the number of leaves that develop from it. The results were obtained in this work as follows: 1. It was found that, of the three fertilizer elements studied, only nitrogen influenced the development of leaves from new bulblets in leaf cuttings; phosphorus and potassium seemed to have no effects. 2. The application of fertilizer during the final stage of bulblet formation was found to be more effective than fertilizer treatment at the stage when the bulblets begin to grow fleshy.

To elucidate the effect of Rhizobium japonicum inoculation and nitrogen application on nitrogen fixing ability of root nodules and finally on the critical character of soybean cultivars, an 11×2×2 factorial analysis experiment was conduceted using 7 species and 4 hybrids of soybean as plant materials, R. japonicum strains, 011 and 019, as inoculants and urea as nitrogen source. The results obtained were as follows: 1. Twenty four indigenous Rhizobium strains isolated from root nodules of soybean plant cultivated at experiment field in Kyungpook National University, were divided into 3 groups according to the intensity of nitrogen fixing ability among several physiological characters. The group having the highest nitrogen fixing ability included 8 strains. These strains showed the small colony size, the transparent alkaline or acidic serum in the litmus milk test and the negative reaction in the nitrite reduction test. 2. In the pot experiment, the nitrogen fixing ability and the allantoin content in the N application plot(N 8kg/10a) decreased at all the growth stages as compared with the control treatment, and the influence of N application was especially severe at the maximum flowering stage. 3. The effect of inoculation was significant at 1% level in root length, stem length and total dry matter, respectively and at 5% level in node number at maximum flowering stage, and at 1% level in stem length, pod number and total dry matter, respectively at the seed filling stage. N application had effect only on the branch numbers at the maximum flowering stage with significant difference of 5% lelvel. Among clutivars the difference was significant at 1% level in stem length and total dry matter, respectively at both maximum flowering and seed filling stage, and at 5% level in node and pod number, respectively at seed filling stage. 4. At maximum flowering stage, the nodule number and the nodule weight significantly increased at 1% level by Rhizobium inoculation, and N application increased the nodule number (p. <0.01) while it decreased the nodule weight (p.<0.05). 5. The nitrogen fixing ability at the maximum flowering stage was significantly enhanced at 1% level by the Rhizobium inocluation and N application in all the cultivars except for D_4 and JTI-800. At the seed filling stage, however, the cultivars that responded to the inocluation were Kwangkyo, D_4 and Danyup×Backchun while those responded to the nitrogen fertilizer were Milyang 5 and Backchun. In Chiquita×Milyang 5, the effect of N application on nitrogen fixing ability was higher with inoculation than with non-inoculation. All the cultivars except for those described above showed higher nitrogen fixing ability with non-inoculation plus non-N application treatment. 6. The effect of Rhizobium inoculation and nitrogen application on the 100 grain weight did not show the significant difference among the total treatment, but among cultivars 1% level of significant difference was observed. On the 100 grain weight, there was significant increase with inoculation at 1% and 5% level in Kwangkyo and Kwangkyo ×D_4, and D_4, respectively, and without inoculation at 1% level in Dangyup×Backchun. The N application brout about significant increase in the 100 grain weight at 1% level and 5% level in D_4 and Chiquita, and Danyup, respectively, while in Kwangkyo and Backchun, and Danyup×JTI-800 the 100 grain weight was reduced significantly at the level of 1% and 5%, respectively. The yield was significantly increased in treatments with inoculation and non-N application at 1% level, respectively. Among cultivars and among each treatment, there was significant difference at 5% or 1% level. Significant difference was observed among clutivars at 1% level, D_4 was the lowest and Backchun the highest in the yeild. Considering the effect on the yeild in each cultivar, with inoculation cultivars resulted in significant increase were D_4, and Kwangkyo and Backchun at 1% and 5% level, respectively, while those increased with N application were D_4 and Chiquita at 1% and 5% level, respectively. Kwangkyo, Danyup×Backchun, JTI-800 and Danyup×JTI-800 were high in yield with non-N application with significant difference of 5% or 1% level. 7. In protein content among the total treatment, the inoculation and the N application resulted in significant increase at 5% and 1% level, respectively. Rhizobium inoculation increased significantly the protein content in Backchun and Danyup×JTI-800 at 1% level, and N application showed significant increase at 5% or 1% level in all cultivars except for Danyup. Fat content had negative correlation with protein content as a whole. Inoculation significantly increased the fat content at 5% or 1% level in all cultivars except for Chiquita, Danyup×Backchun and JTI-800, wherease non-N application increased the fat content in all cultivars except for Kwangkyo×D_4. 8. Soybean cultivars hgh in affinity with inoculants were Kwangkyo, Milyang 5, Kwangkyo×D_4 and JTI-800, while those with indigenous were D_4, Backchun, Danyup×Backchun and Chiquita×Milyang 5. 9. Peroxidase isozyme bands in 11 cultivars were 10 in type. Their Rm values were 0.03, 0.1, 0.5, 0.58, 0.62, 0.7, 0.78, 0.86 and 0.93. Cultivars that showed change in peroxidase isozyme pattern by inoculation were Backchun and Danyup×Backchun, while those by N application were D_4, Chiquita, Backchun and Danyup×Backchun, while those by N application were D_4, Chiquita, Backchun and Danyup×Backchun. Those sensitive to both inoculation and N application were Kwangkyo, Kwangkyo×D_4, Backchun and Danyup×Milyang 5, Danyup, JTI-800 and Danyup×JTI-800. 10. Conculsively the critical characters in soybean investigated were influenced by Rhizobium inoculation more severely than by N application, but in some cultivars inoculation in combination with N application exerted a beneficial incluence.

鹽類濃度가 作物의 養分 吸收와 收量에 미치는 影響 : Ⅰ.培養液 窒素濃度가 사탕무우의 生育狀態와 잎의 窒素含量과 光合成活性 및 炭素分配에 미치는 影響 Ⅰ.Effects of Nitrogen Nutrition on Nitrogen Concentration, Photosynthesis, Carbon Partitioning of Leaf and Growth Status in Sugar Beet

朴愚喆,노-만 테리 慶北大學校 1990 論文集 Vol.50 No.-

This experiment was carried out to investigate effect of nitrogen cut-off treatment on growth status, leaf nitrogen concentration, photosynthesis and carbon partitioning in sugar beet(Beta vulgaris L. cv F58-554HI) under hydrophonics culture condition. The results obtained were as follows: 1. According to the concentration of nitrogen in nutrient medium the growth status was severely affected. However specific weight of one disc leaf was highest in no nitrogen treatment. It is believed that since plant has no enough nitrogen to synthesize new cell, the organized leaves cell of nitrogen cut-off treatment were more thickened than those of control treatment. 2. Photosynthesis of nitrogen deficient leaves was not incidentally decreased with nitrogen decrease. 3. Concentration of leaf soluble protein, nitrogen, total nitrogen in sugar beet treated with nitrogen cut-off was decreased proportionally with nitrogen concentration of nutrient medium. 4. In the nitrogen deficient leaves the concentration of glucose, sucrose and starch was remarkedly higher than those of nitrogen enough leaves. It seemed that the carbon partitioning was irregulated by the nitrogen deficient because the leaves could not use the carbon as sources to built new cell in the lack of nitrogen.

河浩成,金明燦,金正敎,朴愚喆 진주농과대학 1968 진주농과대학 연구논문집 Vol.- No.7

本試驗 結果 米穀 增收의 要件으로 客土와 深耕에 依한 作土層을 增加시킴과 아울러 有機物의 含量을 높이고, 따라서 水?生育에 重要한 要素로 알려진 珪酸質 肥料의 施用 및 不足 ?類를 보충함과 同時에 灌排水 管理 및 耕種關係를 合理的으로 함으로서 現在의 平均 玄米收量 보다 높은 數値의 結果를 얻었다. (1) 客土를 反當 7,500kg 程度 施用함과 有機物 및 ?類 補充으로 莖數, 穗數가 10%, 玄米收量이 12% 增加하였다. (2) 深耕에 依한 作土層의 깊이를 10∼12cm에서 18cm 程度 깊게 함과 同時에 有機物 및 ?類補充으로 客土와 같은 傾向의 成績을 얻었다. (3) 客土와 深耕을 같이 處理한 結果, 客土, 深耕, 單用區에 比하여 莖數, 穗數의 增加는 약간 보았으나 收量面에서는 크게 增加를 보지 못하였다. 이는 當年에 客土, 深耕으로 作土層을 增加시켰다 하드라도, 土壤의 熱度가 잘 이루어 지지 못하였기 때문에 야기된 것으로 본다. (4) 二條竝木區로 坪當 株數를 늘이므로써 收量增加는 認定되지 않았다. 이는 3의 경우와 같다고 하겠으나 他區 역시 坪當 株數가 90株였기 때문으로 본다. To study about an increased yield of rice, this experiment was carried out at five county selected in Kyung Nan province. The essential conditions of increased yield obtained from this experiment were as follows: 1) Supplying with red clay soil to 7,500kg per 10are some of organic matter and mineral nutrition into each field, the stem and ear was increased in number to ten per cent and an unpolished rice to twelve per cent. 2) The coincident results were obtained in deep plowing treatment in order to plow more deep the sub-soil floor of 10∼12㎝ to 18㎝ with supplement of organic matter and mineral nutrition. 3) When the above mentioned two treatments were done together, the stem and ear was moderately increased in number compare with each if the depth of sub-soil was increased according to the supplement of red clay soil and decper plowing, howerer, the soil was not efficiently development during one year for plant to grow well. 4) The two strips planting to increase the number of plant per 0.245 acre was not increased in yield of an unpolished rice. It was seems that the reason also was same as in 3., and that the number of plant was epually ninety in the other all experimental treatment.
