Background p19arf, primarily known as a tumor suppressor, has also been reported to play an essential role in normal development of mouse eyes. Consistently, lack of p19arf has been associated with ocular defects, but the mixed background of the knockout (KO) mouse strain used raised a concern on the accuracy of the phenotypes observed in association with the targeted gene due to genetic heterogeneity. Object We carried out a study to investigate into the efect of genetic background on the manifestation of p19arf KO associated phenotypes. Methods We characterized the phenotypes of novel p19arf KO mouse lines generated in FVB/N and C57BL/6J using a transcription activator-like efector nuclease (TALEN) system in comparison to the reported phenotypes of three other p19arf-defcient mouse lines generated using homologous recombination. Results Ninety-fve percent of FVB/N-p19arf KO mice showed ocular opacity from week 4 after birth which worsened rapidly until week 6, while such abnormality was absent in C57BL/6J-p19arf KO mice up to the age of 26 weeks. Histopathological analysis revealed retrolental masses and dysplasia in the retinal layer in FVB/N-p19arf KO mice from week 4. Besides these, both strains developed normally from birth to week 26 without increased tumorigenesis except for a subcutaneous tumor found in a C57BL/6J-p19arf KO mouse. Conclusion Our fndings demonstrated surprisingly variable manifestation of p19arf-linked phenotypes between FVB/N and C57BL/6J mice, and furthermore between our mouse lines and the established lines, indicating a critical impact of genetic background on functional study of genes using gene targeting strategies in mice.

Malignant tumors of the salivary glands account for a relatively small number(4%) of head and neck tumors, but generate considerable interest because of their remarkable variation in clinical presentation, histologic appearance, and behaviors. Successful treatment of these lesions is a major challenge because of the disposition of these tumors to recur locally as well al distantly. In my study, 46 cases treated from 1982 to 1995 at Korea cancer center hospital are analyzed retrospectively & clinically. The obtained results were as followings. 1. The mean age of patients was 52.7 years old and male & female ratio was 6:4. 2. The common symptoms were mass(45.6%), pain(19.5%), ulcer(13%) and the duration of chief complaints almost was within 6 months. 3. According to histopathology, adenoid cystic carcinoma was most common (43%), and according to the criteria of the AJCC on staging, stages were as followings: stage 1 10.8%, stage 2 23.9%, stage 3 26%, stage 4 39.1%. 4. In treatment modalities, modified triple modalities(chemotherapy + radiation therapy + surgery) was most common(28%), surgery alone was 21.7%, and surgery combined radiation therapy was 19.5%. 5. Among all 46 patients, there were 17%(37%) recurrences. Locoregional recurrence alone occured in 10 patients, distant metastasis alone in 11 patients, and locoregional recurrence with distant metastasis in 2 patients. 6. Overall survival rates of entire group by Kaplan-Meier method was 50.1% at 5 years. 7. The 5 year survival rate was 77.1% in early staged patients, in contrast to 35.3% in advanced patients(P<0.05). 8. The 5 year survival rate for patients without cervical lymph node metastasis was 56.6%, in contrast to 36.9% for patients presented with nodal disease initially. 9. In 5 year survival rates according to histopathology 46.6% in mucoepidermoid carcinoma, 49.2% in adenoid cystic carcinoma, 40% in adenocarcinoma & malignant mixed tumor & malignant myoepithelioma, 100% in terminal duct carcinoma were seen. 10. In 5 year survival rates according to various modalities of treatment, 20% in untreated patients and 83.8% in surgery alone, 68.5% in surgery combined radiation therapy, 46.6% in modified triple modalities (chemotherapy + radiation therapy + surgery) were seen(P<0.01).

The study is purposed to develop a set of construction models for Cyber Home Study System(CHSS) to support the students' self study through internet at the level of elementary, middle and high school students. This is intended to reduce the over spending of the private educational payment, causing the social conflict and antagonism in Korea, and finally to support the public education. The study problems are as follows: 1. Analysis on the social and authentic needs for reducing the private educational payment which causes the social conflict and antagonism in Korea. 2. Setting up the principles to develop the construction model for CHSS to apply the learning theories in support of the learning in the cyber space. 3. Development of a set of construction models for development and construction for CHSS, based on the theoretical developmental principles. The construction model for CHSS developed in this study contains a systemic diagram of the whole CHSS, and 4 major models: a model for management, the model for learning process, the model for content design, and the model for evaluation. The systemic diagram for CHSS demonstrates various components, which consist of the whole system, and the relationship among the components. The model of management identifies the role of each organization by which the CHSS is operated. The Learning process model is classified with 9 sub-models converging on the three factors. These factors are the learner subject, the existence of tutor support, and the relationship to the local school. The models for content design proposes the guideline for design and production of learning content. The evaluation model is composed of three sub models: evaluation for individual learning achievement, evaluation for learning achievement of the tutor supported calss members, and the system evaluation. Finally, 4 kinds of suggestions is suggested to accomplish the purpose of CHSS in terms of environmental resources, learning resources, man power, and advertising and marketing strategies.

권오양,윤동진,김경웅,정민화 韓國非破壞檢査學會 1994 한국비파괴검사학회지 Vol.14 No.2

일반적으로 회전기기의 저어널 베어링 부분은 윤활유 공급의 부족이나 윤활층에 이물질이 혼입되면 시스템의 고장이나 가동중단 등의 원인이 되기도 한다. 따라서 베어링 손상에 기인하는 사고와 관련된 안전운전 문제와 유지비용의 절감을 위해 여러가지 파괴 및 비파괴시험법들이 사용되어 왔다. 본 연구에서는 저어널 베어링에서 가장 발생하기 쉬운 윤활층에의 이물질이 혼입에 의해 야기되는 베어링 파손의 조기검출을 위해 음향방출 기술을 적용하였으며, 전보의 연구에 이어 좀더 정량적이고 체계적인 실험을 수행하였다. 실험실용으로 직접 제작한 모의베어링 시스템을 이용하여 여러 형태의 인위적인 이물질 흔입 상태를 만들어 실험하였으며 베어링 손상 및 결함 형태의 해석을 위해 AE rms level, 파형분석, AE 변수 등의 여러 파라메터를 사용하여 분석 고찰하였다. 그 결과 AE rms level의 변화가 이물질 흔입의 영향에 민감함을 보여주었으며 AE변수등 다른 정보들로부터 손상 원일별로 신호형태를 확인할 수 있었다. Journal bearings in the rotating machineries are vulnerable to the contamination or the insufficient supply of lubricating oil, which is likely to be the cause of unexpected shutdown or malfunction of these systems. Various destructive and nondestructive testing methods had been used for the reduction of maintenance cost and the operational safety problems due to the accidents related to bearing damages. In this experimental approach, acoustic emission monitoring in employed to the detection of incipient failure caused by intervention of foreign particles most probable in the journal bearing systems. Experimental schedules for the intervention of foreign particles was composed to be more quantitative and systematic than last study in consideration of minimum oil film thickness and particle size . The experiment was conducted under such designed conditions as inserting alumina particles to the lubrication layer in the simulated journal bearing system. Several parameters such as AE rms level, waveform, AE energy distribution and other AE event parameter are used for analysis and characterization of damage source. The results showed that the history of damage was well correlated with the changes of AE rms level and the types of damage source signal can be verified using other informations such an waveform, distribution of AE parameter etc.

The purpose of this study is to provide the science teachers with fundamental sources to ameliorate the condition of science education. This study was carried out by a following process-to approach and identify the problems of science education-the statistical comparison and analysis of the materials from the surveying questions concerning the current issues which the science teachers of secondary school have been suffering. Teh issues are surveyed by the classified questions as below: of curriculum, especially experimentation, educational environment, students and teachers. Under the targets of the random sampling investigation was 430 secondary schools, which were located in the direct control city of Taejon, Chungchong nam-do and Chungchong puk-do. Simultaneouely posted on the 16-th day of september, 1991, 319 of the inquiry papers, which were sent back thanksfully. The rate of the replies amount to 74.2 percentage. The remarked materials were compared and analyzed with those of 1974 and 1983. All of the data as below are described by means of the numerical value of percentage and average. The out-put results are represented as below: 1. Until recently, science curricular goals are illustrated to be so desirable, while little difference was made in the contents of science education between the two decaded. The learning methods of students have been greatly altered from the learning by testing to the learning by discovery. Nevertheless the teaching methods of teachers have been clung to the cramming system of education so far. Moreover, school hours in a week are explained to be quite less than demanded. What is needed, most of all, is to fabricate the contents of curriculum, to add school hours in a week, to give priority to the environment education and the environment science, and to expand the special intelligence education in the field of science education. 2. In the science curriculum, the heterogeneous groups are managed through the massed learning and the aspects of experimentation are transfered to the group experiment. On the other hand, the system of learning by inquiry is not well-operated as usual. Hence, it is so much requested theat we should reform the entrance examination system and normalize the science curriculum. 3. Education facilitaies are, if anything, poorly-equipped. It is needless to say that eductional enviorment should be well-equipped with comfortable classroom, school, and convenient condition for experimentation. 4. There is a tendency that most of the students think a science subject as one of the most difficult. Almost students hopes their classes will be carried out by experimentation. Accordingly, the contents of science education should be understandably trans-figured for students to be attracted. 5. The school career of science teacher truned out to be growing higher. Although having more chances to join the research study courses, many of the teachers think they have fewer than hope. Many of them are not satisfied with their teaching professions. Burdensome tasks are of course ascribed to their discontent. Consequently, the problems how we can help the science teachers to uphold the professional faculty, necessary to the practical teaching activities and the accomodation of future society, should be settled as below; to establish the advanced research study cources, to decrease the burdensome tasks of science teachers, and to build up the society so that the teachers may be cordially respected, and to accomplish the institutionalized system so that the teachers may receive everyone`s hospitality.

체세포복제배아 줄기세포의 최근 연구 동향과 관련 윤리지침

NT-hESC research has been receiving much attention, because it holds an immense potential to cure incurable diseases. However, many ethical debates are waged concerning NT-hESC. The debates center around the issue of destroying embryos and acquiring egg donations, because in order to get stem cell lines, the artificial making and destroying of embryos are necessary. Many stem cell scientists around the world continue NT-hESC research within the boundaries of their country’s laws, policies and ethical guidelines. In this article, I first examine the recent NT-hESC research and the naturally accompanying ethical debates regarding the moral status of embryos. Differences in the interpretation and understanding of the moral status of embryos stemming from various cultures, religions and social structures enhance the debate as current scientific technology requires the artificial creation and destruction of embryos in order to get stem cell lines. Second, I examine the ethical issues related to the acquisition of research materials such as egg donation. I explore the National Academy of Science’s “Guidelines for Human Embryonic Stem Cell Research” which contains detailed articles related to policy and ethical considerations. Based on this, I propose that Korea extend the basic ethical and practical regulations in determining ethical and policy guidelines for NT-hESC research.

삼일열 말라리아에 합병된 비장 파열 1예

홍경욱,이정아,김원진,박철민,권혜리,박혜원,엄중식 대한감염학회 2007 감염과 화학요법 Vol.39 No.5

국내의 토착형 말라리아는 삼일열 말라리아로, 1993년부터 재유행이 시작되었다. 말라리아의 중요한 합병증으로 드물지만 비장 파열이 있는데, 이는 주로 삼일열 말라리아에 의해서 발생되며, 국내에서는 1999년 말라리아에 의한 비장 파열로 비장 절제술을 시행한 예가 보고된 바 있다. 현재까지는 비장 파열이 있을 때 비장 절제술이 일차적인 치료로 되어 있으나, 비장 절제술 후의 감염 위험성이 크므로, 활력 징후가 불안정하거나, 출혈이 지속되는 소견이 보이지 않으면 가급적 보존적 치료를 하는 것이 추천된다. 저자들은 비장 파열이 동반된 말라리아 환자에서 비장 절제술을 시행하지 않고 보존적 치료로 호전된 예를 경험하여 보고하는 바이다. Plasmodium vivax has been the predominant Plasmodium species in the Republic of Korea and reemerged in 1993. Spontaneous rupture of malarial spleen is a rare but important complication associated with P. vivax infection. Only one case of spontaneous rupture of malarial spleen was reported in Korea in 1999. Splenectomy is still accepted as the treatment of choice in cases of spontaneous rupture of the spleen. But, considering increased risk of postsplenectomy infecion, splenectomy should be reserved for those patients with severe rupture or those with continued or recurrent bleeding. And conservative treatment should be considered in selected, closely monitored patients. We report a patient with P. vivax malaria who developed a spontaneous splenic rupture and was improved by conservative treatment.
