Cucumbers were grown at 5 levels of Potassium and Nitrogen to stuudy the effect of N,k concentration on growth, yield and content of mineral elements. 1. Growth and yields were increased in N treatment with 16g per plant, and wrer increase in K treatment with 16me per liter. 2. The content of mineral elements of in leaves were higher N teatment than K treatment in content of T-N and Mg, and content of P was high in K treatment. 3. The content of mineral of petiole, fruit and Xyleme sap. were detected. The content in Xyleme sap, was most in N treatment all content expect of NO₃-N. NO₃-N and K were contented a lot in petiole Ca was contented a little in fruit. In K treatment, No-N and K were contented a lot in petiole, and the others were contented in Xyleme sap. Ca was contented a little in fruit. 4. The content of mineral in soil was detected in N and K treatment content of mineral was a little after than before treatment P while in case of P content was higher before treatment 5. absorption of water in cucumber plants was increased in N treatment with 8g per plants, while decreased in the K treatment 8 me per plant. The contents of chlorophyll was increased as the levels of Nitrogen was increased in N treatment, however, decreased on young leave as the level of Poassium was incresed in K treatment.

구분옥,이은영,최경숙 曉星女子大學校 藥學大學 學生會 1990 曉星藥誌 Vol.5 No.-

In order to search of new drug effect, ten N-Substituted anthranilate derivatives were synthesized. Methyl anthranilate was synthesized by the reaction of methanol in the presence of conc. sulfuric acid and 5-hydroxyethylanthranilate was synthesized by the reac-tion of ethanol saturated with hydrogen chloride gas. According to Schotten-Baumann method, these acid amides could be synthesized by the reaction of methylanthranilate or 5-hydroxyethylanthranilate with acid chloride (CICO-?? : x=H, p-chloro, o-chloro, p-nitro, m-nitro)in the presence of 10% sodium hydroxide solution. The structure of these compounds was identified by IR and NMR Spectra.

Purpose: Holmium:YAG lasertripsy for the 33 patients with lower ureteral calculi compared the outcome with other results using Lithoclast and ultrasonic lithotripsy. Materials and Methods: Thirty-three patients with symptomatic urinary calculi underwent Holmium:YAG lasertripsy from March 1999 to December 2000. Twelve patients were treated with Ultrasonic lithotripsy and twenty-one patients with Lithoclast lithotripsy from April 1997 to October 1999. All calculi of the above patients were located in their lower ureters. The size of ureter stones was ranged from 3.5 mm to 12 mm (mean 6.54 mm). Results: The age of the patients ranged was from 19 to 62 years (me~n 35.7 years). After a single ureteroscopic lasertripsy calculi were conlpletely cleared in 83 % of the cases for the patients with lower ureter calculi. The immediate complications of lasertripsy were gross hematuria, fever, and flank pain. However in the long term follow up (up to 3 months after the procedures) there were no further complications, such as, vesicoureteral reflux or ureteral stricture. In other two lithotripsies Lithoclast and Ultrasonic lithotripsy accomplished calculi were completely cleared in 71 % and 74 % of cases respectively. But Holmium:Y AG lasertripsy is cleared in 94 % effectiveness. Holmium:Y AG lasertripsy is more effective than two other methods compared by stratified analysis that unmasking from confounding factors such as impacted situation. Conclusions: Lasertripsy with Holmium:Y AG laser is considered effective and safe procedure for the lower urinary calculi lithotripsy (Ultrasonic, Lithoclast).

沈慶久,李景俊,劉種勳 成均館大學校 科學技術硏究所 1988 論文集 Vol.39 No.1

The beneficial role of vesicular-arduscular mycorrhizae(VAM) for the growth of fruit trees has already been well demonstrated in many countries, but little has been studied about VAM in Korea. so far, researches concerning physiological aspects of VAM have been abundant compared to researches on the ecological sides in fruit trees. Especially, the study about VA mycorrhizae fungi indigenous to apple orchard soil has been less studied. The studies described here were undertaken to identify the genera of VAM fungi living in the soil wherein apple trees rooted, and to observe in fected roots of host plants in apple orchards in Suwean, Taegu, and Naju area. The results odtained were as follows. Apple roots infected by VAM fungi, and VAM fungi noticed in the rhizosphere soil were opserved in Suweon and Taegu, but only spores have been shown in Naju. Identified genera of the fungi investigated in the rhizosphere soil were Glomes sp. The VAM fungi showed a circular from, spore diameter and wall thickness were respectively 306㎛ and 17㎛. The form of attached hyphae was funnel shape, and that of vesicle was circular.

法典을 통해 본 17~18세기 서울의 변화

이경구 서울시립대학교 부설 서울학연구소 2005 서울학연구 Vol.- No.25

In this article, the changes that happened in the Seoul area during the 17th and 18th centuries, in terms of the size of the city and also the life style of the citizens inside it, are examined through various sources of codified laws(法典). Since the mid-17th century, the damage inflicted upon the Joseon dynasty by two devastating wars(兩亂) with the Japanese and the Ching dynasty had been being healed, and the population of the Seoul area was again starting to increase. The increase in population eventually led to the enlargement of the city itself. The existing 'Prohibition markers' that were based upon the outlines of the Four Mountains(Sasan Geumpyo/四山禁標), which have served as traditional symbols for the dynasty's prohibitive definition of banning further developments in the area, became obsolete, and a new line comprised of new streams and rivers came to serve in presenting a newly recognized area that was called 'Seongjeo Shibri/城底十里'(10 Ri units outside the realm of the Capital). Local districts had to be revised accordingly, and the government incorporated such changes into the administrative system. As the size of the city continued to grow and the population continued to increase, new life styles of the Seoul city residents started to emerge. The entire process of such changes are literally well described in the 『Sugyo Jibrok;受敎輯錄(Compilation of the Sugyo documents)』 and the 『Shinbo Sugyo Jibrok/新補受敎輯錄(Revised version of the Sugyo documents Compilation)』, which were sets of codified laws that were enacted and published during the late 17th and early 18th centuries. Unlike the previous codes of laws, these two new codes of laws had much larger chapters arranged for the Restrictive regulations(禁制) in the Criminal law section(「刑典」). Such restrictive regulations were in most part addressing issues such as accumulating and brandishing luxurious articles, committing economic foul plays, and developing nearby areas of the Seoul city. And the most primary targets of such restrictions were the powerful individuals or Houses inside the Seoul area or the wealthy Jungin/中人 figures. What called for the frequent issuing of restrictive regulations was the general atmosphere of the society that has been continuing to loosen since the 17th century. The people became less alerted against the Chinese Ching dynasty, and became more acceptive to the Ching culture. As a result, entertainment, luxurious articles and a new sub-culture of amusement were introduced to the Joseon people and became a general trend. In the 18th century, the Seoul city literally developed a new phenomenon(referred to as '時體/Shichae', namely the 'Trend of the Time') in which the residents of the Seoul city invented new fashions, and relayed them to other local areas. The scholar-officials(the Sa-Daebu/士大夫 figures) in local areas were fairly critical of this new trend that demonstrated certain social structure-related problems in which the Seoul capital was in solid, almost proprietary lead of the 'Trends of the Time'. The reason that they were so critical of this new fashion was because such trend was representing the birth of a new social structure in which only the Seoul citizens were becoming prominent leading figures of the country thanks to the development of the Seoul city area. For example, in the process of appointing governmental officials, whether someone was from a distinguished family(門閥) in the Seoul area or not became a crucial factor, and subsequently human resources in the Seoul area started to almost monopolize the office seats inside the government. Civilian merchants(私商) were protected by the powerful Houses(㔟家), enlarged their business transactions and shared their new found profits with many partners(from various social classes) in the Seoul area. This led to the formation of a new profit chain that connected the powerful Houses in the Seoul area, the messengers(家人) from those Houses, and the civilian merchants with each other.

寒蘭組織培養에 있어서 Rhizome의 生育과 Shoot 分化에 관한 硏究

沈慶久,柳美先,李貞植 成均館大學校 科學技術硏究所 1986 論文集 Vol.37 No.1

This study was carried out to accelarate the growth of rhizome and shoot formation of Cymbidium kanran. Rhizome used as materials were prepared by seed strile culture and rhizome-tips were placed on the basal medium (Murashige & Skoog) which were supplemented with growth substances. The results obtained were summarized as follows: 1. Shoot formation at the rhizome-tips was the best in the media supplemented with 0-0.1mg/l BA. Rhizome growth was stimulated in the media supplemented with 0.1mg/l NAA and 4-8mg/l BA. 2. When organic matters were added to basal medium, a noticeable promotion of rhizome growth was observed in the medium containing activated charcoal. 3. The growth of rhizom was promoted when 4% sucrose, 3g/l pepton, or 4g/l yeast extract were added to basal medium. 4. Incorporation of 1.0mg/l BA and 10^-3M L-arginine, L-aspartic acid stimulated shoot formation remarkably under light condition. 5. Growth of rhizome according to light or dark treatment was better under dark than under 16hr illuminated light condition and the rhizome cultured under dark condition was more effective for shoot formation.

주민중심적 도시근린개발모형의 과제

전경구 大邱大學校 社會科學硏究所 2001 社會科學硏究 Vol.9 No.3

본 논문은 근린을 단위로 그 지역주민의 개발의 주체가 되어 추진하는 주민중심적 근린개발모형의 이론적 배경을 고찰하고, 실천적인 측면에서 이 개발모형이 어떠한 문제점을 가지고 있는가를 경험적으로 평가하며, 이를 기초로 이 개발모형을 개선하기 위한 방안을 모색하는 것을 목적으로 하고 있다. 그리고 주민중심적 근린개발모형을 주민이 집단 또는 조직을 형성하여 단독으로 추진하는 주민주도형, 주민과 민간기업이 협력하는 합동개발형, 주민과 정부가 협력하는 공동생산형, 주민과 다른 전문적인 민간조직이 협력하는 전문기관 위탁형으로 구분하여 이 개발모형의 특징과 문제점을 분석하고 있다. 분석 결과 주민주도형 개발모형의 경우에는 무임승차, 공공재의 과도한 이용, 주민대표성 확보, 주민갈등 등과 같은 다양한 문제가 발생하는 것으로 나타났다. 협력형의 경우도 이론적으로 기대했던 긍정적인 효과보다는 부정적인 결과가 많이 나타나고 있는데, 특히 합동개발형의 경우에는 경제적 이익을 추구하고자 하는 목적에 치우쳐 과밀개발, 주거환경의 악화, 공동체의 파괴 등의 문제가 발생하는 것으로 나타났다. 이와 같은 제반 문제점을 개선하기 위해서는 주민참여와 자원봉사활동을 강화할 수 있는 방안을 모색할 필요가 있고, 미국의 경우처럼 주민조직을 기술적, 재정적으로 지원하기 위한 제도적 장치가 필요하다는 것을 밝히고 있다. 그리고 협력형의 경우 지방정부의 역할이 중요하다는 것도 밝히고 있다.
