방선균 분리주 MT2617-2의 배양액으로 부터 phospholipase C (PLC) 저해물질인 MT2617-2B를 n-butanol 추출 및 column chromatography 법을 이용하여 분리하였다. MT2617-2B는 IR ^13C- 및 ^1H-NMR 그리고 ESI-MS에 의한 구조분석 결과, 한 개의 hemiketal ring, polyhydroxyl 및polymethyl groups으로 구성되었으며 side chain으로 한 개씩의 malonate 및 guanidine group을 가지는 분자량 1057의 macrolide 화합물이었다. 따라서, MT2617-2B를 기존의 macrolide 항생제인 copiamycin 및 niphithricin A로 동정하였다. 한편, MT2617-2B는 methanol 용액에서 실온에서 방치하였을 때 도일한 분자량을 가진 두 개의 이성질체를 생성하였다. PLC γ1과 -β1에 대해 각각 25 및 50㎍/㎖의 IC_50 값을 가지며, Staphylococcus aureus 와 Candida albicans에 대해서는 항균활성을 나타내지만 Escherichia coli에는 나타내지 않았다. A phospholipase C (PLC) inhibitor (MT2617-2B) was isolated from the culture broth of actionmycetes isolate MT2617-2 by the extraction with n-butanol and column chromatographic techniques. The molecular weight of the inhibitor was 1057, by the spectroscopic analyses of IR ^13C- and ^1H-NMR and ESI-MS. The chemical structure of MT2617-2B was found to be a macrolide compound consisted of a hemiketal ring, polyhydroxyl and polymethyl groups, which had a malonate and guanidine group as its side chain. MT2617-2B produced its two isomers having the same molecular weight by standing in methanol solution at room temperature. Therefore, MT2617-2B was identified as copiamycin and niphithricin A, macrolide antibiotics. The values of IC_50 against PLC γ1 and PLC-β1 were 25 and 50㎍/㎖, respectively. MT2617-2B had antimicrobial activities against Staphylococcus aureus and Candida albicans, but not against Escherichia coli.

During last two decades, the policies and strategies of regional development has changed gradually in accordance with the shift of the economic and social environment which is mainly distinguished by economic growth, and enlargement and differentiation of the social structure in Korea. Most of all, the first decade was marked by economic rationalism based on efficiency strategies and quatitative growth, but the second decade conducted the pursuit of socio-economic balance of the spatial development in the regional dimension as well as in the national based on equity. And so it may be recognized that recently the trends and strategies of regional development have directed to equity-oriented development policies. In this context, the Saemaul Movement must be understood as an equity-oriented micro regional development to accomplish self-reliance for an integrated rural development in village unit level. Looking back upon the Saemaul Movement, even since it began in the year 1970, it has been developed more powerfully with the slogan of diligence, self-reliance and cooperation throughout the country, and the objectives of the movement: improved life environment, provision of community facilities, increased income and changes in the attitudes and values of inhabitants resulting from their participation and cooperation in village-level developing projects, have been almost achieved. However, since the beginning of 1980's, the Saemaul Movement has been under the necessity of establishing a new development policy for area-wide development because the basic objectives of village-level have been approximately accomplished and then it is necessary to pursue area-wide projects in need of scale-economics in village group level. That is to say, in the period of 1980's the policies and strategies of Saemaul Movement have been toward a cooperative development between villages, an area-wide development, apart from village unit development, which is called now "Saemaul Kwang Yeok Kwon" in Korean word. As stated above, the trend of regional development is toward the necessity of area-wide development in Saemaul Movement with special reference to micro-level regional development. However, the meaning, rolls and guidelines of it are not defined exactly. And so, this paper is intended to define the meaning of area-wide development in Saemaul Movement (Saemaul Kwang Seok Kwon), to define the roll and basic guidelines for development policy for it and to delineate the boundaries of it. Area-wide Development in Saemaul Movement is hard to define but generally speaking, it may be said that its meaning is the developing of a group of villages composed of 5-10 village units communally with express purpose of working jointly and constructing the integrated settlement area. In developing the, area-wide development in Saemaul Movement successfully, first of all, it is especially desirable that it has proper boundary in accordance with homogeneous characteristics and functional interaction between village units. And then it is necsssary to establish the basic principles for its development in detail. Briefly speaking the main emphasis of the development policy of area-wide development in this paper is given to the following. Firstly, systematizing hierarchical structure of micro-level regional development with special reference to the spatial arrangement of village unit, area-wide development in Saemaul Movement, Eup, Myon integrated settlement area and Gun(county) integrated settlement area. Secondly, establishing the integrated rural development and providing the communal facilities based on village group, especially placing the focus on basic need approach. Thirdly, Inducing the evolutional change of village cooperative scheme (VCS) into area-wide development. Fourthly, promoting inhabitants participation in public developing projects and enhancing the autonomous management of area-wide development in Saemaul Movement based on communal cooperative consciousness.

지역개발의 입장에서 본 새마을운동의 재조명

趙喆柱,朴鍾浩,高秉浩 청주대학교 새마을연구소 1985 새마을硏究論文集 Vol.2 No.-

Korea has experienced the rapid economic growth, which greatly changed our way of life, since the early nineteen sixties. By the extraordinary pace of urbanization and industrialization were accompanied the emergence of regional disparity in income and the relative low level of quality of life in the rural region. Two principal activities were implemented to cope with these problems; one was the regional development which began in 1964, the other was the Saemaul Undong which was launched in 1970. The regional development and the Saemaul Undong have been implemented independently without mutual coordination although they have similar objectives, similar projects and usable resources. This phenomenon has resulted in the dichotomy of institution and organization which has diminished the effects of the regional development and Saemaul Undong. To maximize the effects of the development is it necessary to integrate the Saemaul Undong with the regional development. The purpose of this article, therefore, is to establish the relationships clearly, which have been obscure, between the regional development and Saemaul Uudong.

Dental magnetic materials have been applied to removable prosthetic appliances, maxillofacial prostheses, obturator and dental implant but they still have some problems such as low corrosion resistance in oral environments. To increase the corrosion resistance of dental magnetic materials, surfaces of Sm-Co and Nd-Fe-B based magnetic materials were plated with TiN and then electrochemical corrosion test were performed in 4 kinds of electrolyte solutions(0.9% NaCl. 1% lactic acid, 0.05% HCl and modified Fusayama's artificial saliva). From this study, corrosion behavior, amount of elements released, mean average surface roughness values and the changing of mean surface microhardness values were measured comparing with control group of non-sputtered plating magnetic materials. The results were as follows: 1. TiN layer coated on magnet grows into preferred direction with lamellar structure and its thickness is 3.0㎛. 2. Sm-Co base magnetic materials coated with TiN have good corrosion resistance in 1% lactic acid and their pitting corrosion can not be seen. 3. Nd-Fe-B base magnetic materials coated with TiN showed good tendency of corrosion resistance in 0.05% HCl solution. 4. The amount of elements released from both Sm-Co and Nd-Fe-B base magnetic materials coated with TiN were more significantly decreased than that of uncoated magnetic materials. 5. The mean surface roughness values of both Sm-Co and Nd-Fe-B base magnetic materials coated with TiN were smooth than that of uncoated magnetic materials after corrosion test. 6. The decreasing rate of microhardness of both Sm-Co and Nd-Fe-B base magnetic materials coated with TiN were lower than that of uncoated magnetic materials after corrosion test. 7. Dental magnetic materials coated with TiN produced various corrosion products such as TiO, TiO₂, Ti₂O₃on the surface and resulted in better corrosion resistance than uncoated magnetic materials. In conclusion, it is considered that the corrosion problem of dental magnetic materials could be solved to some extent by EB-PVD with TiN on the surface of dental magnetic materials.

본 연구는 새계화벼를 공시하여 간척지 중염답(0.3~0.4%)에서 관개수 염농도에 따른 생육 및 수량성을 검토하고자 유수형성기에 5일간 염수를 처리하여 시험한 결과를 요약하면 다음과 같다. 1. 관개수 염분농도가 높을수록 벼 출수는 1~2일 지연되었고, 출수기 지상부건물중은 가벼워졌다. 2. 간장과 수장은 관개수 염분농도가 높을수록 짧아졌다. 3. 관개수 염분농도가 높을수록 수당 립수가 적어 ㎡당 립수가 적었으며, 등숙비율이 낮고 현미 천립중이 가벼워, 쌀 수량은 민물 관개(무처리)의 330㎏/10a에 비해 관개수 염분농도 0.1%는 94%, 0.3%는 85%, 0.5%는 76%, 0.7%는 71%의 수량을 얻었다. 4. 관개수 염분농도가 높을수록 완전립 비율은 낮아졌다. 따라서 간척지에서 중염도 토양(0.3~0.4%)에서 벼를 재배하여 유수형성기에 한발이 닥쳐 저류지 등 염분 농도 0.7%의 물로 5일간 담수하여도 쌀 수량은 29% 정도 감수되고 쌀의 품위도 저하되지만 어느 정도 수량은 얻을 수 있을 것으로 생각된다. This experiment was conducted at the Kyehwado Substation of the National Honam Agricultural Experiment Station(NHAES) RDA, Korea. The experimental field contained 0.38% NaCl in soil solution. The experiment was involved five treatments (control, 0.1, 0.3, 0.5, 0.7%) in a randomized complete block design with three replicates, saline solution was applied only one time at panicle formation stage for 5 days. Saegyehwabyeo, a japonica rice variety was used in this experiment. In yield components, Spikelets number per ㎡ decreased with increasing salinity level, particularly in the 0.7% of saline solution water. This factor affected the most yield reduction among the components. The percentage of ripened grain was inclined to decrease with increasing salinity level. 1,000 grain weight decreased with increasing salinity level but it was lest affected by salinity among yield components. The reduction of milled rice yield decreased significantly with increased saline water level, in detail 6% of yield reduction at the 0.1% saline solution, 15% at the 0.3%, 24% at the 0.5%, and 29% at the 0.7% saline solution level compared with control respectively. Results indicate that the gaining of rice yield could be reliable performance in terms of economical benefit for rice production even though high reduction of yield occurred at high salinity levels on a reclaimed saline soil in Korea.
