羅鐘城,盧承杓,金達壽 韓國作物學會 1978 Korean journal of crop science Vol.23 No.1

벼의 신품종 밀양 2003에 관하여 지대별 안전재배 체계를 확립하고저 파종기와 묘대일수를 각각 달리해서 평야지대인 이리와 산간지대에 속하는 진안 시험지에서 실험한 결과를 요약하면 다음과 같다. 1. 파종기와 묘대일수를 달리한 묘의 소질에 있어서는 파종기와 묘대일수가 연장될수록 초장과 엽수는 증가되었다. 묘소질의 양부를 결정하는 지상부건물중/초장은 4월 10일파종의 40일∼50일묘가 높아서 조파 조식의 효과가 인정되었으며 그 정도는 산간지대에서 더욱 현저하였다. 2. 재배시기이동으로 본 기본영양생장성은 커서 영양생장기간이 4월 10일간기파종한 40일묘에 있어서는 53일간이었고 4월 20일 적기파종의 40일묘는 8일간이 단축되였으며 만파재배 4월 20일의 40일묘는 무려 13일간이나 영양생장기간이 단축되였고 그정도는 묘대일수가 연장될수록 단축되였다. 3. 출수기의 반응은 파종기와 묘대일수에 따른 차리가 있으나 그정도는 파종기에 의한 출수지연보다도 묘대일수의 연장에 따른 출수지연이 보다 현저하므로 이 품종에 관한 지대별 적정재배한계기는 평야지대인 이리의 경우이앙기는 6월 10일까지이며 4월 10일 파종일때에는 40일∼60일묘이고 4월 20일파종에 있어서는 40일-50일묘이다. 진안과같이 산간지대에서는 적정 이앙한계기가 5월 30일 이내이며 40묘가 가장 적합하였다. 4. 묘대일수와 이앙기는 지연될수록 주당수수는 감소하는 반면에 주당영화수는 증가되는 경향이다. 등숙비율은 낮아지며 특히 산간지대에서 더욱 저조한 편이다. 5. 광합성능력에 의한 경엽내의 동화물질의 축적과 탄수화물 관계는 이앙기와 묘대일수가 연장될수록 낮고 탄수물질의 축적이 많을수록 탄수화물의 분배양이 많었다. 6. 수양성은 평야지대인 이리에서 보통 4월 20일파종 50일묘의 수량(585kg/10a)에 비해서 우위에 있는 재위에 있는 재배시기는 4월 10일 파종의 40일묘>4월 10일파종 50일묘=4월 20일파종 40일묘>4월 10일 파종 60일묘 등이고 진안과 같은 산간지대 일수록 수양성은 낮으나 그폭은 매우 좁아서 조파조식의 효과가 현저하였다. An experiment was carried out to find out effective heading date and period of limited ripening in different regions of climatic conditions by sowing date and length of nursery stage of a new variety Milyang 23. Since varieties of Tongil line have a character of premature heading, these do not show the symptom of senescent even though length of nursey stage was delayed. And the delay of heading date is due to late transplanting date, on the other hand, length of nursery stage delayed.

羅鍾城 圓光大學校 農村副業問題硏究所 1978 農村副業問題硏究 Vol.1 No.-

벼의 新品種 密陽23號에 關하여 地帶別 安全栽培體系를 確立하고져 播種期와 苗垈日數를 各各 달리해서 平野地帶인 裡里와 山間地帶에 屬하는 鎭安試驗地에서 實驗한 結果를 要約하면 다음과 같다. 1. 播種期와 苗垈日數를 달리한 苗의 素質에 있어서는 播種期와 苗垈日數가 延長될수록 草長과 葉數는 增加되였다. 苗素質의 良否를 決定하는 地上部 乾物重/草長은 4月 10日播種의 40日∼50日苗가 높아서 早播 早植의 效果가 認定되었으며 그 程度는 山間地帶에서 더욱 顯著하였다. 2. 栽培時期移動으로본 基本營養生長性은 커서 營養生長期間이 4月10日 早期播種한 40日苗에 있어서는 53日間이었고 4月20日 適期播種의 40日苗는 8日間이 短縮되였으며 晩播栽培 4月20日의 40日苗는 무려 13日間이나 營養生長期間이 短縮되였고, 그程度는 苗垈日數가 延長될수록 短縮되였다. 3. 出穗期의 反應은 播種期와 苗垈日數에 따른 差異가 있으나 그程度는 播種期에 의한 出穗遲延보다도 苗垈日數의 延長에 따른 出穗遲延이 보다 顯著하므로 이品種에 關한 地帶別 適正栽培限界期는 平野地帶인 裡里의 境遇 移秧期는 6月10日까지이며 4月10日播種 일때에는 40日∼60日苗이고 4月20日播種에 있어서는 40日∼50日苗이다. 鎭安과 같이 山間地帶에서는 適正移秧限界期가 5月30日以內이며 40日苗가 가장 적합하였다. 4. 苗垈日數와 移秧期는 遲延될수록 株當數穗는 減少하는 反面에 株當穎花數는 增加되는 傾向이다. 登熟比率은 낮아지며 特히 山間地帶에서 더욱 低調한 편이다. 5. 光合成能力에 의한 莖葉內의 同化物質의 蓄積과 炭水化物 關係는 移秧期와 苗垈日數가 延長될수록 낮고 同化物質의 蓄積이 많을수록 炭水化物의 分配量이 많었다. 6. 收量性은 平野地帶인 裡里에서 普通 4月20日播種 50日苗의 收量 (585㎏/10a)에 比해서 栽培時期에 의한 ① 4月10日播種區의 40日苗>② 4月10日播種 50日苗 ③ 4月20日播種區의 40日苗> ④ 4月10日播種 60日苗 等이고 鎭安과 같은 山間地帶일수록 收量性은 낮으나 그幅은 매우 좁아서 早播早植의 效果가 顯著하였다. The experiment was carried out to find out effcctive heading date and period of limited ripening in different regions of climatic conditions by sowing date and length of nursery stage of a new variety Milyang 23. Since the varieties of Tongil line have a character of premature heading, these did not show the symptom of senescence even though the length of nursery stage was delayed. And the rethrdness of heading date was due to late transplanting and increasing nursery auratiom duration. Summary To establish a standard cultivating system in Iri which belongs to coastal plain and in Jinan which belongs to middle alpine region for the new rice variety, Milyang 23, a experiment was carried out with several different sowing times and nursery duration. 1. The length ofstems and the number of leaves for the seedling in different sowing date and nursery duration were intcreased by extending the nursery duraion. The dry weight/stem length, of the aerial part which effects on the relative quaility of seedling was conformed at the result of the early sowing and transplanting time because the 40~50 days old seeding sowed on 10, April showed a tendency to increase the percentage of, dry weigdt/stem lenght. 2. The variation of vegitative growth by changing cultivating time was wide. Thus, the vegitative growing period was 53 days in the 40 days old seeding sowed early on 10, April, but it was reduced for 8 days for the 40 days seeding sowed timely on 30, April, and also it was reduced for 13 days in the same aged seedlings sowed late on 30, April. These tendency showed to be reduced by increasing the nursery duration. 3. Although the reaction to heading date dapend upon to increase the nursery duration rather than due to late sowing date, the optimum limiting transplanting date of this variety in Iri was 10, June. Iin case of sowing on 10, April, the optimum age of seeding was 40~60 days and 40~50 days for seedliag sowed on 20, April. In the middle alpine region like Jinan, the optimum limiting transplanting date was before 30, April and 40 days old seedlings were adaptable. 4. Number of panicles per a hill were reduced by retarding the nursary duration and the transplan lanting time. Nevertheless, the number of grain per a hill showed a tendency to be iacreased, but the percentage of filled grains were reduced, particulary in the middle alpine area. 5. The accumulation of carbohydrate in leaves and stems by photosynthesis was decreased by delaying transplanting time and nursery duration. 6. The better productive cultivating time which produced higher yield than 50 days seedling which the normal sowing date is 20, April in Iri (585㎏/10a) was 40 days seeding sowed on 10, April>50 days seedling sowed on 10, April=40 days seedlings sowed on 20, April>60 days seedling sowed on 10, April. Whereas, the productivity was low by cultivating at middle alpine area like Jinan, but the variation of it was very small. Therefore, the effect of early sowing and transplanting was significant.

時代的 狀況變動에 따른 行政理論의 發展的 考察 : IST PERSPECTIVES AND APPROACHES

라종성 연세대학교 대학원 1985 원우론집 Vol.13 No.1

The archaeologist has been back the beginning of man to as early as seven hundred thousand to a million years B.C. But beginning to accumulate organized government and the existence of public officials is about 6000 years' ago. If it is the fact really, public administration has about 8000 years' history. But scholars have begun to study public administration from the mid of 16C. And public administration has been developed according to its changing society; political, cultural, socioeconomic backgrounds. From this point of view, it is very important to study developmental stage of public administration theory through its changing environments. Especially it is more important because this study provides developmental motivation to those trying to solve the societal problems of the future. Theory of public administration comes from public administrative phenomena and public administrative phenomena reflects social phenomena. Therefore, this study explored developmental stage of public administration through its social backgrounds. Especially in observations of developmental stage in public administration theory, we can find radical social changes in 1960's and according to this, some new approaches and perspectives to public administration emerged. Some of these characteristic theories are New Public Administratton and Public Choice. Theory. Finally, when we transplant public administration theory of western developed country to Korea as a developing country, we must be cautions not only because indiscreet transplantation of it might arise some public administrative problems but because both sides of particularism and universalism in public administration are to be considered simultaneously.

冷害肢帶의 水稻生育과 稔·不稔 潁慤의 養分吸收에 關한 研究

羅鍾城 圓光大學校大學院 1984 學位論叢 Vol.12 No.-

In 1981, rice was considerably damaged by abnormal low temperature. lhe cold damage was characterized by the reduction of percentage of ripened grains due to the occurrence of sterility and the delay of heading. Cold damages at various growth stages, and varietal differences of physio-morphological response to low temperature among Japonica, Indica, and Tongil lines have been studied by several researchers. In this paper, to determine the effects of low temperature on the growth and nutrition of rice, the following experiments were carried out; varietal response to low temperature in the regions with different elevation; changes of cropping seasonal culture; balanced fertilization rate experiment between nitrogen and silicate; content of inorganic element in chaff with different specific gravity. To achive the goal, analyses of various plant parts were made. The results obtained are summarized as follows 1. Regional differences of heading response to low temperature were observed among varieties. The differences of days between region were bigger in Tongil lines than Japonica lines. Especially Milyang #42 and Hangangchal byeo might belong the cold sucep tiple group, since the varieties were severely delayed their heading in the high moutainous region as compaired to plain region. 2. Varieties with higher grain sterility by low temperature have higher total nitrogen content, but tended to have lower potassium and phosphate contents in the flag leaf. 3. High content of total nitrogen, low contents of potassium and silicate were observed in the sterilized grain chaff and the opposite result were noted in the fertilized grain chaff at the ripening stage. The results reveal that the balance of these mineral element may play an important role in ripening and possibly cold tolerance. 4. Results of different seasonal culture experiment, heading stage was delayed by destructive cold temperature or late transplanting. Plant analysis revealed that above poor plants also had higher total nitrogen content, but lower silicate in the flag leaf and sterile chaff. Total nitrogen and silica contents to accumulated in flag leaf between yield was significant high correlation. The chaff of late transplanting and sterility was high total nitrogen. Relationship between silicate absorption and total nitrogen of chaff was significant high correlation. 5. Ripening temperature after heading stage was influenced total nitrogen of chaff. Phosphate, potassium, calcium and silicate contents of chaff increased high ripening temperature but total nitrogen decreased. therefore, inorganic element contents of chaff 'was closely connected with grain sterility. 6. As a result of balanced fertilization experiment between nitrogen and silicate for decreasing cold damage, application of increasing level of nitrogen resulted in increasing the contents of total nitrogen and phosphate in both sterile and fertile chaff. The contents of potassium and calcium were the highest at the level of nitrogen 10~15Kg per 10a. but magnessium was higher rather high at the low nitrogen levels. It is interesting that at level of nitrogen, over 6% higher silicate content were noted in the fertile chaff than in the sterile chaff. 7. Application of increasing level of silicate fertilizer decreased total nitrogen contents, but increased the contents of phosphate, potassium and silicate in the chaff. Increasing rate of silicate content by increasing silicate addition was remarkably higher in the fertile chaff than in the sterile chaff'. 8. Analyses of grain groups with different specific gravity revealed that well develped grains have lower total nitrogen content, but higher potassium and silicate contents in the chaff. The result was agreed with the above resulted obtained. The result also demonstrated that nutritional bal ance between nitrogen, and potassium and silicate in the chaff would play very important role for ripeness.

땅콩비닐 일피복재배에 관한 연구

李起白,羅種城,盧承杓,李敦吉 韓國作物學會 1979 한국작물학회지 Vol.24 No.3

땅콩을 온도조건 및 재실거리를 이동시켜 시험한 결과를 요약하면 다음과 같다. 1. 지온은 비닐 무피복구에 비하여 비닐 피복구가 4월중순경에 4.6℃ 나 높았으며 초기생육의 왕성으로 햇빛을 차단하므로 6월중순부터는 지온이 떨어졌다. 2. 생육기간중에 착화수는 상당수에 이르나 그중 수정하여 자방병이 생기고 지하에 침입하여 결실하는 것은 58.8%이다. 3. 개화수의 대부분이 1~4지에 착생하나, 자엽정분지는 발육이 개화수의 60~70%를 점육하고 있다. 4. 총개화수는 분지의 차별 착생율에는 심한 차가 인정되었다. 5. 주당협실비율 및 결실비율은 밀식보다 소식에서 높았고 만파보다 조파에서 좋았다. 6. 유효개화 한계기는 7월중순이다. 7. 식물체분석은 경보다 엽이 N, Ca, Mg 함량이 많으나 P2O5, K2는 엽보다 경에서 많았다. 8. 수량은 무피복 5월 10일(129kg/10a)에 비하여 비닐피복 5월 10일이 9%, 4월 20일이 49% 증수되었다. Peanut was cultured with varying planting density and sowing date with and without vinyl-film mulching. Vinyl-film mulching raised soil temperature 4.6~circC higher than the non-mulched during April and early May, but later-on the soil temperature was similar between the two treatments. The ripening and slender grain ratio increased with closer spacing and earlier sowing. Compared with ordinary cultural practices of May 10th sowing without mulching the peanut yield increased by 9% by mulching sown May 10th, and by 49% by mulching and early sowing April 20th.
