On the basis of the specific interrelationship between the species or variety of leguminous crops and the species or strain of nodule bacteria, Rhizobia, the rhizobial species and strain must be effectively chosen for the successful inoculation. The present paper describes on some results of the isolation and taxonomic study on the native rhizobial strains isolated from the nodules of five species of leguminous crops such as numerous varieties of soy bean, lespedeza, birdfoot trefoil, ladino and red clovers. The isolated strains of soy bean nodule bacterium, Rhizobium japonicum were grouped through the inoculation test on variety Changdanbaikmock into the effective, noneffective and toxic strain for the nodule formation. In the study of the effect of some inorganic and organic nitrogenous compounds on the growth of Rhizobium japonicum strain Ac 20, a promotive response was showed by asparagine, and glutamine, but hydroxylamine, nitrite, hydrazine and azide was inhibitory at the concentration of 10^(-2)M/ℓ in mannitol-yeast extract basal medium. In the physiological characteristics each strain showed somewhat different activities of the indole-3-actic acid formation and hydrogenase and discussed with these characters in relation to nodule forming ability.

임선욱,문무상,Lim, Sun-Uk,Moon, Moo-Sang 한국토양비료학회 1983 한국토양비료학회지 Vol.16 No.4
한국산(韓國産) 이탄(泥炭), 화산회토(火山灰土) 및 무기질(無機質) 답토양(畓土壤)에 유기물(有機物)에 대(對)한 일련의 토양화학적성상(土壤化學的性狀)의 비교연구(比較硏究)로부터 본(本) 실험(實驗)은 김포(金浦), 평택(平澤), 김제(金堤) 및 영동(永同)의 이탄(泥炭)과 제주도(濟州島) 화산회토(火山灰土) 그리고 수원(水原)의 답토양(畓土壤)으로부터 각각(各各) 부식물(腐植物)을 유출(油出)하고 Hymatomelanic acid와 Humic acid로 분획(分劃)하여 가시(可視), UV 및 IR 광역(光域)에서 흡수(吸收) Spectra를 측정(測定)하여 비교(比較)하여 보았다. Humic acid와 Hymatomelanic acid는 UV 및 가시광역(可視光域)에서 극대(極大)나 극소(極小)의 Peak를 가지지 않으며 파장(波長)의 감소에 따라 단조로운 Optical density의 증가를 보이는 Spectra를 나타내었다. 또한 이탄(泥炭) 및 화산회토(火山灰土)와 답토양(畓土壤) 부식물간(腐植物間)의 흡수(吸收) Spectra는 이 범위의 광파장역(光波長域)에서 별다른 상이성(相異性)이 없었으나 화산회토(火山灰土), 이탄(泥炭), 무기질(無機質) 답토양(畓土壤)의 순(順)으로 완만(緩慢)한 경사(傾斜)를 이루었다. Humic acid와 Hymatomelanic acid의 IR spectrum의 주요한 흡수대(吸收帶)는 $3400cm^{-1}$, $2900cm^{-1}$, $1720cm^{-1}$, $1625cm^{-1}$, $1400-1450cm^{-1}$, $1200-1250cm^{-1}$, $1050cm^{-1}$ 등이며 토양형간(土壤型間)의 상이점(相異點)은 미미(微微)하나 Hymatomelanic acid는 파수(波數) $2900cm^{-1}$에서 흡수(吸收) peak를 가지며 파수(波數) $1720cm^{-1}$ 부근에서의 흡수(吸收)가 $1625cm^{-1}$ 부근보다 큰 반면에 Humic acid는 $1625cm^{-1}$ 부근이 $1720cm^{-1}$ 부근보다 큰 흡수(吸收) band를 이루었다. Humic acid의 관능기(官能基)의 함량(含量)은 공시(供試)된 토양형(土壤型) 사이에 큰 차이(差異)가 없었으나 화산회토(火山灰土), 이탄(泥炭), 무기질(無機質) 답토양(畓土壤)의 순(順)으로 전산도(全酸度)가 낮았고 Carboxyl기(基)의 함량(含量)이 적었다. To characterize humus fractions in soil, visible, ultraviolet and infrared absorption spectra of humic acids in alkaline solutions and hymatomelanic acids in ethanol solutions extracted by Stevenson's method from paddy rice soils, peats, and volcanic ash soils were analyzed. The spectra patterns of both fractions in visible and ultraviolet ranges did not have any peak and the absorbance decreased as the wavelength increased. Visible and ultraviolet spectra of the solutions from all the peats, volcanic ash soils and paddy rice soil were very similar each other but absorbances were slowly declined in the order of volcanic ash soils, peats and mineral paddy soils. The infrared spectra of the two solutions appeared in a typical pattern, showing a few broad peaks. The main absorption bands were in the regions of $3400cm^{-1}$ (hydrogen bonded OH), near $2900cm^{-1}$ (aliphatic CH), $1720cm^{-1}$ (C=O of COOH, C=O of carbonyl), $1625cm^{-1}$ (aromatic C-C conjugated with C=O and/or COO-), $1400-1450cm^{-1}$ (CH stretch), $1200-1250cm^{-1}$ (CaO stretch of phenolic OH or OH-deformation of COOH) and $1050cm^{-1}$. The hymatomelanic acid fractions, however, had spectra that were characterized especially by very distinct absorption at $2900cm^{-1}$ and $1720cm^{-1}$, for aliphatic CH and carbonyl stretching vibration respectively in addition to the weaker bands for COO- or aromatic CH vibration at $1625cm^{-1}$, as compared to humic acid. No differences were noted in the general patterns of the spectograms of both fractions extracted. Analyses of the functional groups revealed little differences between peats and paddy soils, although total acidity and the content of carboxyl groups were decreased in the order of volcanic ash soils, peats and mineral paddy soils.

우리나라 企劃制度의 效率的 施行方案에 관한 硏究 : 第1次 및 第2次 國土綜合開發計劃을 中心으로

This Study deals primarily with the effective implementation of a plan for national land development in Korea. In 1960's, the conventional social structure had been changed by the progress of politics, economic and social culture. This was rapidly evolved by the governmental program for economic development and national land develpment. Specially, national development policy got to be the basis of the modernization. Therefore the development of national land in Korea has been started in 1960's. Meanwhile, the basic frame work of National Physical Development Plan was decided in 1968. The 1st Comprehensive National Physical Plan was established in 1971 and accomplished by succeeding 10 years. The 2nd Comprehensive National Plan was established in 1981 and it's basic policy was based on the settlement at national land base to spread localized age. But, the effective implementation of the 1st and 2nd Comprehensive National Physical Plans were in difficulties for unsettlement of governmental organization, lack of special planner, shortage of an executive budget and insufficient of control function, this situation is due to disparity of regional investment and insufficient of an executive plan in the 1st and 2nd Comprehensive National Physical Plans. Consequently, Comprehensive Nationai Physical Plan must get to be execution, coordination and control effectively. First, National Physical Plan get to have a connection with national land plan, economic plan and budgeting in government and National Physical Plan must be essentially consulted with Economic Planning Board which generalizes the investment plan. Secondly, A yearly executive program must be established in relation to National Physical Plan. This program will be included a scale, contenst, a location and a term of construction work to national land development projects. Thirdly, In order to perform national land development plan and regional plan effectively, National Physical Plan must be established a special resource in addition to general budget. Therefore the matter can be solved through the foundation of National Land Development Fund, the refundmen of development returns and the collection of development share. Aside from themes, it must positively be divised to mitigate a institutional regulation and participate capital.

임선욱,문무상,Lim, Sun-Uk,Moon, Moo-Sang 한국토양비료학회 1983 한국토양비료학회지 Vol.16 No.3
In a series of studies on the chemical compositions and properties of organic matter from peats, volcanic ash soils and paddy rice soils, a comparative study on the composition and the fractional distribution of nitrogenous organic matters were undertaken for the elucidation on their characteristics. The results obtained are summerized as follows. 1. Gimpo and Peongtaeg peats showed higher content of organic matter, more than 60%, than Gimje and Yeongdong peats, and there is a great difference between the two groups in total-N, CEC and ash content. 2. The content of Lignin, Hollocellulose and Hemicellulose in organic matter was 12-25%, 15-31% and 7-14% respectively, and Gimpo peats were lots of Lignin content compared to others. 3. Sixty seven to eighty eight percent of the total-N in the soil was hydrolysable by 6 N-HCl and they were decreased in the order of volcanic ash soils (86.4%), mineral paddy soils (77.2%) and peats (72.3%). 4. The fractionations of acid hydrolysable organic-N were ${\alpha}$-amino acid-N(25-45%), unidentified-N (12-50%), amino sugar-N (1-7%) and ammonium-N (12-25%). 5. Almost same pattern in the amino acid composition of the acid hydrolysates of peat and soil organic matter was showed in the thin-layer chromatogram. 김포(金浦), 평택(平澤), 김제(金堤), 영동산(永同産)의 이탄층(泥炭層)과 송당(松堂) 및 제동(濟東)의 비교적 유기물 함량(含量)이 많은 화산회토(火山灰土) 및 무기질답(無機質畓)의 작토층(作土層)으로부터 채취한 토양시료(土壤試料)를 사용(使用)하여 그 이화학적(理化學的) 특성(特性) 및 유기태(有機態) 질소(窒素)의 형태별(形態別) 분포(分布)를 조사(調査)한 결과(結果)를 상호(相互) 비교(比較)하였다. 1. 김포(金浦), 평택산(平澤産) 이탄(泥炭)은 유기물(有機物) 함량(含量)이 60% 이상(以上)으로 김제(金堤), 영동산(永同産) 이탄(泥炭)보다 많았으며 그 외 김질소(金窒素), CEC, 회분함량(灰分含量)도 차이(差異)가 있었다. 2. 이탄(泥炭)의 Lignin, Hollocellulose 및 Hemicellulose의 함량(含量)은 각각(各各) 12~25%, 15~31%, 7~14%, 이었으며 김포(金浦) 이탄(泥炭)은 다른 것과 비교하여 Lignin 함량이 많았다. 3. 6N-HCl 산가용성(酸可容性) 질소(窒素)는 전질소(全窒素)의 67~88%이었으며 화산회토(火山灰土)(86.4%), 무기질토양(無機質土壤)(77.2%) 이탄토(泥炭土)(72.3%) 순(順)이었다. 4. 산가용성(酸可溶性) 질소중(窒素中) 분획정량(分劃定量)한 4종류(種類)의 유기태(有機態) 질소(窒素)는 아미노산태(酸態)(25~45%), 미지태(未知態) (12~50%), 암모니아태(態)(12~25%), 아미노당태(糖態)(1~7%) 순(順)이었다. 5. 이탄(泥炭) 및 토양유기물(土壤有機物)의 산가수분해물중(酸加水分解物中) 아미노산(酸)의 종류(種類)는 유기물(有機物)의 급원(給源)에 따른 큰 차이(差異)는 인정(認定)되지 않았으나 각(各) 함량(含量)은 조건(條件)에 따라 변동(變動)되는 듯하다.
