Familial adenomatous polyposis (FAP) is an autosomal dominant syndrome, typically characterized by multiple colorectal adenomas and increased incidence of colorectal carcinomas if it is not treated. Moreover, a variety of extracolonic manifestation are seen. The prevalence of thyroid tumors developing in patients with FAP is about 1∼2%. Generally, papillary thyroid cancer indicates low mortality but ,however, as people get older, the cancer becomes more aggressive. So, the operation is required. Recently we experienced a case of FAP, presenting with papillary thyroid carcinoma, and reported with a brief review of literatures.

제7차 수학과 교육과정에 대한 교사들의 인식과 적용상의 문제점

문선미,박종서 진주교육대학교 과학교육연구소 2000 科學敎育硏究 Vol.26 No.-

This study is designed to find out the understanding of school teachers in relation to the 7th mathematics curriculum revised in accordance with the changes and needs of the day and the problems coming from its application in classes with the help of a questionnaire research, and to come up with the solutions. We worked with first-grade and second-grade teachers in such districts as Chinju, Hadong, Kimhae and Yangsan with the aid of questionnaires, using 285 copies as a means of analysis materials. According to the research, the subjects trunk of the purports or contents of the 7th mathematics curriculum as proper in principle, feeling that it is too ideal a curriculum that doesn't take the given actual condition intro consideration. The subjects hold that the fact that what was originally intended from the 7th mathematics curriculum at the outset fail to be realized in the fields of education is ascribable to such factors as lack of loaming materials, an excessive number of students, too much leaning per period, and lack of their understanding of the curriculum and teaching methods and so forth. We would like to make the following suggestions with a view to working out the problems coming from the application of the 7th mathematics curriculum. First, the number of students per class should be reduced to less than 30. Because it is hard to form mathematic concepts through specific operational activities, playful learning, and intention-exchanging activities due to the present number of students, and it is extremely difficult to carry out level-based classes. Second, standardized learning materials should be provided. Though a large number of learning materials are needed in view of the math text, the actual condition of the schools leaves much to be desired on account of lack of teaming materials, which inhibits classes from going smoothly. Therefore, at least such basic materials as numerical models, cards, and building blocks should be distributed. Third, it is necessary to make policy-related efforts to develop a variety of training programs for the teachers and to expand training opportunities. I would like to suggest that teacher-training programs should be worked out in relation to top-notch thinking or various kinds of theories on math and the reorganization of the curriculum with a view to involve more teachers. With this in mind, such institutions as EBS and Teachers' Training Center, etc. should hopefully work out and implement high-quality teachers' training programs. Fourth, it is necessary for teachers to change their minds. The subjects find it hard to teach their students because there are too many to teach and lean by period and the contents of learning have been upgraded. This is attributable to the teachers' views on the textbook: They regard it as absolute. So it is absolutely necessary for the teachers to apply the curriculum to each class situation based on changes in their minds and to look upon the textbook as one of materials to attain the purpose of education and to be possessed of insight as experts well- versed in the curriculum in a more broad perspective. With this in mind, the teachers should make continuous efforts and at the same time the higher educational institutions also make policy-related efforts to encourage more teachers to make a real study and to make sincere efforts.

『素問·疾態論』에 대한 硏究

장종렬,김명수,서대선,김종호,천상묵,금경수 한국전통의학연구소 2002 한국전통의학지 Vol.12 No.1

A study on the Byungtae Ron(病能論) of the So Moon(素問), one of the classic book of oriental medicine, was carried out analytically for the right comments. The principal ideas obtained summarized as follows; Neng(能) is similar to tae(熊) in the pronunciation and the meaning of a chinese character. Byungtae(病能) means the state of the symptoms and the pulse condition of the diseases, etc. It deals with ethological factor, mechanism of disease, the condition of an illness, method of diagnosis, rule of treatment, technique of treatment of seven diseases and taking this seven diseases as a example, mainly discuss the technique and significance of clinical observation and the pathogenesis and condition of an illness, so It named 「Byungtaeron(病能論)」 In this chapter it shows we can grasp condition of illness well only if we classify the pathogenesis and condition of an illness in details. this viewpoint provides the foundation of development in oriental diagnostics. It places emphasis on pulse feeling in this chapter, so it describes pulse condition of various kinds of diseases in details. It also presents how to compare pulse feeling like comparison between Inyoungmaek(人迎脈, arterial carotid communes, the pulsation of which is easily felt beside Adam's apple) and Ch'onkumaek(寸口脈, the radial artery on the wrist where the pulse is routinely taken for diagnosis), between right and left Ch'onkumaek(寸口脈), between Yangmyungsangdong (陽明常動) and Taeyangbudong(太陽不動), Soyangbudong(少陽不動), etc. In this chapter it explains pulse feeling occupies a high position in the diagnosis of diseases in 『Huangdi's internal Classic(黃帝內經)』 period and the technique of pulse feeling is already plentiful and minute. In this chapter it presents 「Tongbyungyich(同病異治, to apply different methods of treatment to the same kind of disease)」 theory, taking tangible syndromes as examples. this is prominent viewpoint of determination of treatment based on the differentiation of symptoms and signs and much influence development of later ages' medicine. On the ground of oriental medical theory, it may bring about different symptoms in the same disease according to stage of disease, the seasons, the regions, the constitution of patient, therefore surely adopt different technique of treatment, this differentiation of symptoms and signs is an important character in oriental medicine.

단치소요산이 구속 스트레스를 가한 흰쥐의 뇌내 catecholamine 함량변화에 미치는 영향

황귀서,이기선,박종형 한국환경독성학회 1998 환경독성보건학회지 Vol.13 No.2

To elucidate the preventive effect of Danchisoyosan (DS) on stress, we investigated the physiological change of rats which were applied immobilization stress. For immobilization stress, rats were placed in restrainer for 12 hours a day for 3 days. During application of stress, body weight of rats was measured. After sacrifice, 8 organs were taken for measurement of organ weight. Brain was sectioned into 4 parts that are Frontal Cortex, Corpus Striatum, Hypothalamus and Hippocampus. Each part was homogenated and its catecholamine and serotonin contents were measured with HPLC. In our study, stress mainly induced increase of concentration of neurotransmitters in brain without other significant physical change of rats. DS inhibited stress induced changes of neurotransmitter content in brain.

Case Reports : Dermatofibrosarcoma Protuberans Arising from a Burn Scar

Jong Keun Seo,Kyung Jong Cho,Ju Hyun Kang,Deborah Lee,Ho Suk Sung,Seon Wook Hwang 대한피부과학회 2009 Annals of Dermatology Vol.21 No.4

Malignant neoplasms arising in burn scars are well known. In previous literature, 25 cases of burn scar sarcomas were reported. However, dermatofibrosarcoma protuberans is very rare and only two cases have been reported. A 43-year-old Korean man presented with multiple erythematous clustered plaques and nodules and a skin-colored subcutaneous mass on the chest after a severe burn injury at the age of 8 years. A biopsy specimen revealed dermatofibrosarcoma protuberans. The tumor was excised widely to include the surrounding burn scar. Herein, we report this third case of dermatofibrosarcoma protuberans arising from a burn scar. (Ann Dermatol 21(4) 416~418, 2009)
