To evaluate the accuracy of an domestic auto ref-keratometer(MRK-2000), the author analyzed the differences in spherical equivalent value, spherical power, cylinder power and keratometric base curve between automated refraction with MRK-2000 and subjective refraction. 124 patients(248 eyes), who did not have any ophthalmic disease were divided into three groups, myopic group(up to -5.00 diopter:D, spherical equivalent, 151 eyes), high myopic group(over -5.25D, 35 eyes) and hyperopic group(62 eyes). They were examined with MRK-2000 and subjective refraction was performed by an ophthalmologist and results were analyzed by paired T-test. The mean spherical equivalent value of automated refraction in each group were -2.03 ± 1.16D, -6.71 ± 2.16D, +1.77 ± 1.45D, respectively and -1.85 ± 1.13D, -6.02 ± 2.10D, +1.27 ± 1.20D in subjective refraction. The mean spherical power of automated refraction were -1.61 ± 1.15D, -6.25 ± 2.01D, +1.28 ± 1.51D, respectively and -1.55 ± 1.11D, -5.78 ± 1.96D, +0.93 ± 1.25D in subjective refraction. The mean cylinder power of automated refraction were -0.83 ± 0.77D, -1.38 ± 1.10D, +0.96 ± 0.76D respectively and -0.60 ± 0.82D, -0.97 ± 0.82D, +0.67 ± 0.85D respectively in subjective refraction. Except spherical power in high myopic group, all differences between automated and subjective refraction show statistical significance. The mean keratometric base curve of automated keratometry was 7.85 ± 0.42 ㎜ and 7.89 ± 0.32 ㎜ in subjective keratometry and these two differences did not show statistical significance. This study revealed that there was statistically significant difference between automated and subjective refraction and show myopic shift in myopic group, which were compatible to the results of other auto ref-keratometer.

몇 가지 發育因子가 딸기 겹무늬病菌, Dendrophoma obscurans(Ell. & Ev.) Anderson 의 柄子殼과 柄胞子 形成에 미치는 영향에 대하여 비교 검토한 結果를 要約하면 다음과 같다. 1. 本 菌의 柄子殼과 柄胞子는 순수 合成 培地에서는 전연 形成되지 않았다. 2. 供試한 7種의 發育因子 中에서 柄子殼 形成에 가장 效果的인 것은 malt extract 이었으며 다음은 yeast extract, thiamine-HCI 順이었으나 柄胞子는 thiamine-HCI 添加에 의하여 가장 많이 形成되었다. 그 적정 濃度는 malt extract가 1∼5%, yeast extract는 1%,, thiamine은 400r/1 이었다. 3. 柄子殼과 柄胞子의 多量 形成에 적합한 培地 조성은 Czapek's Agar의 炭素源을 gluose로 대치하고 여기에 thiamine 100r/1와 malt extract 0.5%를 混合 添加할 경우 가장 效果的이었다. 4. 柄子殼 및 柄胞子 形成에 대한 發育因子의 促進效果는 S-2 菌株가 他菌株에 비하여 有意的으로 컸다. The experiments were conducted to clear the effects of growth factors on the production of pycnidia and pycniospores of Dendrophoma obscurans (Ell. & Ev.) Anderson. The results obtained are summarized as follows: 1. The fungus failed to form mature pycnidia on synthetic media such as Elliot's Agar, Czapek's Agar and Richara's Agar. 2. Of the 7 growth factors tested, malt extract was the best for pycnidia formation, and followed by yeast extract and thiamine-HCI, while thiamine-HCI was the most effective for formation of pycniospores. The proper concentration of malt extract, yeast extract and thiamine-HCI were 1∼5%, 1% and 400r/1, respectively. 3. Malt extract 5g/1 with thiamine-HCI 100r/1 was the most effective in increasing the amount of formation of pycnidia and pycniospores, when the sugar source in Czapek's Agar as the basal medium was replaced with glucose. 4. Of 4 isolate used, S-2 isolate produced more pycnidia and pycniospores than did the other isolates, when the growth factors were added in the basal medium.

Background and Objectives : Palindromic rheumatism (PR) is known to be triggered without any obviously inciting events in most patients, although, in a few cases, attacks have been noted to relate to another events such as weather change, childbirth, ingestion of certain foods, or over-exercise. The aim of this study was to characterize the triggering factors on palindromic attacks. Materials and Methods : We evaluated sixty-four patients with PR for the presence of triggering factors and the relationship between attacks and triggering factors by interview of patients. We considered that there was an probable association between episodes and PR, if episodes within 24 hours prior to PR had triggered at least 50% of all attacks and a definite association between episodes and PR, if episodes within 24 hours prior to PR had triggered 100% of all attacks. Results : In 15 patients (35.9%), there was a possible association between episodes of PR and initiating events. In 8 patients (12.5%), there was a definite association between episodes of PR and initiating events. The triggering factors were physical over-activity including exercise (19/64: 29.7%), foods, such as rawfish, crab, and chicken, including alcohol (19/96: 19.8%). However, there were no difference between the groups with and without the triggering factor in sex ratio, duration and onset of PR, the positive rate of rheumatoid factor and involved sites. Conclusion : Our observations showed that PR was triggered by physical over-activity more than in previous reports and hypersensitivity to foods was a causative factor in some patients with PR. However, patients with triggering factors had a similiar clinical profile to patients without triggering factors.

지역개발의 입장에서 본 새마을운동의 재조명

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.

The purpose of this study was to develop a teaching model for elementary schools which takes advatage of the internet. For the purpose, this study carried out aalyzing ad synthesizing the internet-based teaching models which had been developed by other researchers. This study has especially operated an internet cafe for elementary classroom students/teacher/parents as an experiment of this study. As a result, this study identified and analyzed two internet-based teaching models; (1) Resource-centered teaching model and (2) Exploratory project teaching model. The Resource-centered teaching model is a teaching model in which the teacher makes a search for instruction-related materials and presents students the materials, when it is possible to access the internet in the classroom. The Exploratory project teaching model is a teaching model in which students themselves search for learning materials according to the subject. This study established a classroom cafe(www.daum.net/ayo51) in the internet, and let the classroom members participate in the bulletin board, data room and/or chatting room. The teacher's diary and classroom diary let the teacher and students exchange emotions with one another. Students' parents also participated in the cafe, asking questions or discussing with the teacher. The processes and results of this study let the co-researchers reach the following conclusions. First, educators in the elementary education have to make a rational/systematic approach to take advantage of the internet materials for students. Second, the teacher has to think of the internet as another effective method of the school education, and be active in using the internet during his/her teaching. Third, educators have to develop continuously the contents for the internet classroom which are appropriate to students' intellectual developments and their learning circumstances.

The fish catches of Korea have been radically reduced because environments of coastal area are contaminated and fishery resources are reduced by the overfishing. So the government has enforced various policies for fostering fishery resources to increase the income of fishers and to provide smoothly with aquatic products. However, we are confronting with many problems resulted from the stagnation of fisheries industry from 1990. The problems are analysed with three points: socio-economic aspects, coastal environmental aspects and institutional aspects. In socio-economic aspects, many fishers are overburdened with the financial expenditure due to the excessive investments. Because of the reduction of relative incomes, the reduction of export increase rate, many fishers have threaten the fundamental fishery resources by doing as unlawful fishing activities. Also a cooperative association of fishery tend to center on the financial works rather than contribute to increasing the fisher's incomes. In coastal environmental aspects, the quality of water in the coastal areas is deteriorated by the filling-up and the land reclamation by drainage which are directed by the local governments. As a results, the deterioration makes a production of fishery decrease. So, it is needed to sustainingly protect the quality of water in the coastal areas. In institutional aspects, the fishery resources promotion policy ruled by the government has some doubts of practical effects because of the differences of jurisdictional areas and the services' scopes between the central government and the local government and a separation of jurisdictional departments in local government. Therefore, the investigation and analysis of the institutional arrangements must be preceded to contribute to the fishery resources-promotion policy.

Background : Previous data have been reported that subtype B is prevalent in South Korea, but neither the extent nor the proportion of subtypes could be evaluated. This study was designed to analyze the distribution of HIV-1 subtypes, temporal instructions and transmission dynamics between epidemiological groups. Methods : 1,280 Koreans had been diagnosed as HIV seropositive during the period 1985 to 2000. Among them, 134 individuals were selected for this molecular epidemiological study. 134 DNAs were isolated from uncultured or cultured peripheral blood mononuclear cells. V3-V5 (0.7 kb) fragment of HIV-1 env gene was amplified by nested polymerase chain reaction and was sequenced. Results : HIV-1 isolates from thirty-seven homosexuals were all subtype B (100%). On the other hand, 66 isolates from 94 heterosexuals were subtype B (70%) and 28 were non B subtypes (30% : 13 A, 4 C, 2 D, 8 E , 1 G). Only subtype B strains were isolated from 73 males who were infected with HIV inside Korea while 16 B and 20 non B subtype strains were isolated from 36 males who were HIV infected outside of Korea. However, B and non B strains were isolated half and half from females who were infected inside Korea except one. Conclusion : The HIV-1 subtype B strains are prevalent in Korea from the early HIV infection until present in both homo and heterosexuals. Non B strains have been transmitted from men who were infected outside Korea to their spouses and casual partners. So, we need further study to monitor subtype B and non B HIV transmission in epidemiological groups of Korea, (Korean J Infect Dis 33:311∼318, 2001)
