To object of this study was to analyze the effects of air pollution of industrial park to the environmental-ecology characterization in the Sa-Sang Park and the vicinity of South Gate in Mt. Geumjung. 6 transects(each size 400m2 were set up and surveyed each park. The relationships of the distribution of dominant groups for forest vegetation structure and the environmental condition between the Sa-Sang Park and the vicinity of South Gate San-Sung Amusement Park were analyzed by similarity index, frequencies of tree species, importance value, soil pH, SO2ㆍCOㆍNO2 and PM10 density of air and tree vitality. The results obtained were as follows, 1. For analysis of vegetation structure in the Sa-Sang Park, upperstory of forests was mostly consisted of Pinus thunbergii Parl and partly of Alnus japonica Steudel. In midstory, major components were Alnus japonica Steudel and partly of Pinus thunbergii Parl. In lower story Rhus sylvestris S. et Z, which was known to be resistant to air pollution, was found in large number. While the vicinity of South Gate in Mt. Geumjung has various species and stable forest vegetation, upperstory of forests was mostly consisted of Pinus rigida Mill and partly of Pinus densiflora S. et Z. Quercus serrata Thunb. Quercus mogolicα Fischer. Alnus hirsuta Rupr. In midstory, major components were Pinus rigida Mill and Alnus hirsuta Rupr. In lower story Rhododendron yedoense Maximowicz var. poukhanense(Le'v.) Nakai. and Rubus crataegifolius Bunge, Lespedeza bicolor Turcz. Similarity index in the Sa-Sang Park and the vicinity of South Gate in Mt. Geumjung was 42.31%. 2. Frequencies class of tree species were analyzed A(23.53%), B(17.65%),C(11.76%), D(5.88%), E(41.18%) in the Sa-Sang Park and A(29.41%), B(29.41%). C(23.53%), DC5.88%), E(11.77%) the vicinity of South Gate in Mt. Geumjung 3. Soil pH decreased to below pH 0.7 in the Sa~Sang Park as compared to pH 4.9in the vicinity of South Gate in Mt. Geumjung. In addition Water content decreased to below 7.7% in Sa~Sang Park as compared to 9.3% the vicilli앙 of South Gate in Mt. Geumjung. While SO2ㆍCO2 density of air and tree vitality were higher than those in the vicinity of South Gate in Mt. Geumjung. It is concluded that the Sa~Sang Park is only afraided to survive stronge tree species which resist to air pollution and decrease a function of city park in a few years that tree vitality of the Sa~Sang Park is higher than those in the vicinity of the South Gate in Mt. Geumjung. as a result environmental factorsCfor example SO2ㆍCOㆍNO2 and PM10 density of air, Water content, Soil pH and so on).

Background and objectives : The long-term survival in patients with non-Hodgkin's lymphoma (NHL) after conventional dose chemotherapy is about 35% and the rest of the patients tend to have relapse. So, in relapsed or refractory NHL, we compared the outcome of patients undergoing high-dose chemotherapy with autologous peripheral blood stem cell transplantation(APBSCT) with only salvage chemotherapy of cisplatin, dexamethasone, mitoxantrone, and etoposide(CDME). Materials and methods : From June 1993 to December 1999, 25 patients with relapsed or resistant NHL were treated with CDME regimen as salvage chemotherapy. Twelve patients were received four cycles of CDME chemotherapy, and 13 patients were received high-dose chemotherapy with APBSCT following two cycles of CDME chemotherapy. Results : The median follow-up duration was 12.8 months(range:4-68). The overall response rate was 41.7% (complete response rate 25%, partial response rate 16.7%) in 12 patients with CDME only. Thirteen patients who were treated with high-dose chemotherapy with APBSCT achieved 61.5% complete response rate and 15.4% partial response rate, with an overall response rate of 76.9%. The estimated 3-year progression-free survival rate was significantly higher among patients who received high-dose therapy than patients who received CDME only(41.5% vs 20.0%, p<0.05). And, 3-year overall survival rate was significantly higher among patients who received high-dose therapy(51.3% vs 25.0%, p <0.05). Conclusions : In relapsed or refractory NHL, CDME chemotherapy is an effective salvage chemotherapy and allow peripheral blood stem cell collection. Also, high-dose chemotherapy with APBSCT following CDME is superior to CDME salvage chemotherapy only.

시대적 변화에 대응하는 학교 경영

朴亨圭 전주교육대학교 1995 論文集 Vol.31 No.-

Types of schools can be classified into 3 type-bureaucratic, communal, political types. But, in reality, the 3 thpes of schools are usually mixed in a school. People concerned in education can be classified into 3 kinds-people planning and managing the education in general(ministry of education, provincial office of education), people teaching students in each level of schools(teachers), people benefited by the edcation (students, parents, inhabitants). Generally speaking, the first group has so called the formal views on it, and the third group has the popular views on it. The current situation of our education in Korea is a confused, unstable situation in which the two educational views (mechanical view, organic view) confronting and conflicting each other and the two educational functions (essential function, instrumental function) confronting and conflicing each other are flowing together in a mixed state. Such situation is influencing each school in which the three kinds of people concerned in our school education insist so strongly their opinions and rights on their own respectively. Such situation requires a multi-dimensional approach in our school management, Such multi-dimensional approach comprises the essential dimension and the instrumental dimensions, and the intrinsic and extrinsic dimensions. Such approach expects in our school educaion l) the cultural relevance 2) the political correspondence 3) the economic efficiency and 4) the educational effectiveness. A school managar in such situation requires l) to establish the self-identity of his own, 2) to exersise the autonomy and control in a reasonable way in his school and 3) to put into practice the essential social behavior norms in the school life. 1) The self-identity can be constructed as such total, comprehensive answers from the following questions. a) Who am I? What am I? b) What am I to do? What am I to be? c) What do they expect me to do? What do they expect me to be? 2) In a school organization, the internal order is the order which the autonomy of its members pursue and the external order is the order which the control of its members pursue. The order which both autonomy and control produce in a school organization is productive in that both contribute to achieving the objectives which the school organization pursue. 3) Whether the situation of a school is bureaucratic, communal or political, the people concerned in the school education have to keep up with such social behavior norms as the following. a) Law-abiding Our democracy is a system based on the "law-abiding." It is the first essential step we all have to take. If we had some unsatisfaction with the current law, first of all, we should try to amend the law, not to violate it. b) Accountability Each of us should discharge one's accountability in a school to which he belongs. First of all, each teacher have to teach his students so sincerely, and each student is required to study as well as he can. c) Dialogue Dialogue means a talking-with each other who has an opponent opinion about a problem. If two persons (groups) have an opponent opinion, they should keep on talking with each other leading to a compromise, harmony and a mutual agreement. Our democracy is based on the mutual agreement. Dialogue makes away with the self-righteousness. d) Open-heartednenss In our democracy we protect one's privacy of an individual from being known. But we hope to make everything public in a public organization. As the proverb goes, "The outside of an absolutism is clean but its inside is unclean. The outside of the democracy is unclean, but its inside is clean." In a public organization, its business including monetary and personnel affairs, has to be open to the public at any time, in any case, if necessary. e) Mutual restraint and cooperation Our democracy never admits one's self-righteousness. The theologian Nieber said, "Democracy is possible because we have the ability to go to the righteousness, and it is necessary because we have the desposition to go to the unrighteousness." Our democracu provides us with the cooperation as well as the check and balance. As we see in the above paragraph, the "law-abiding and accountability" will be more emphatic in a bureaucratic situation of a school, the "dialogue and open-heartedness will be more necessary in a communal situation of a school, and the "mutual restraint and cooperation" will be more requisite in a political situation of a school.

We have used molecular biology technique to label the side chains and backbone of HBV preS1(1-56) with stable isotope (??) during E. coli over-expression and purified the protein to near homogeneity. The expression level of ?? labelled preS1(1-56) seems to be ∼15% of the total protein. to characterize the secondary structure of the labelled protein, circular dichroism was used. In different buffer conditions including pH 3.3 and pH 7.4 the protein seems to be devoid of any stable secondary structure probably suggesting that the N-terminal portion (preS1(1-56)) of HBV preS1 might be unstructured before binding to its target cells.

학교평가 개선을 위한 점진적 노력

박형규 全州敎育大學校 初等敎育硏究所 1998 初等敎育硏究 Vol.9 No.-

The evaluation of schools(School Based Evaluation) has been started in our primary and secondary schools because it is regarded as unevitable and essential to raise the educational accountability and competitiveness. A research for the need of school evaluation shows 89.9%(yea-parents), 67% (yea-teachers). Another study for the substantial school evaluation system insists that it would rather be put into practice after about ten years when the educational reform projects are carried out so well. It will take so many years and so much efforts for the school based evaluation to run in good condition and situation. And now Ministry of education is operating 6 model schools for the school based evaluation America has a history of about one century in school evaluation (accreditation system). The above facts recommendations are based on the examining some papers related to school based evaluation. To improve our school evaluation system more successfully with our great perseverance and sincerity, we need the ceaseless and faithful process of our efforts. Such efforts should go together with some recommendations below through examining the whole process of our school evaluation in terms of the functions of school evaluation. 1. For all the people concerned with the school evaluation(principals, teachers, supervisors and parents), pre and in-service training for the preparation of the school evaluation should be more strengthened. 2. Our recognition for the school evaluation should be substantially changed from passive to active direction, from negative to positive attitude. 3. More specific plan(objective, process, effect, etc) for the findings of school evaluation should be made by the people concerned in order to make full use of the essential data for our school management. Our school evaluation would rather be started with the purpose of improving the situations and abilities of school management and should extend its utilization scope gradually. 4. A sufficient and wide-scope of opinion survey for the "stakeholders" should be put together and examined specifically in school evaluation. 5. We should support financially and administratively to make our school evaluation system successfully.

1. The purpose of this study is to reflect reality of sports to legal structure. This author classified types of sports related accidents as match accidents, school accidents, leisure and living sports accidents. Out of such accidents common factors such as 'the provider of virtue' and 'user' could be deduced and this author reviewed what kinds of obligations must be shouldered by these people respectively. In particular this author stressed the fact that disproportionate emphasis is placed on malfeasance in disposition of dispute over the sports accidents. Malfeasance is a method for seeking relief through money after the accident. However default in an obligation enables supplementary completion when it is not performed or imperfectly performed. Thus if object which must be performed is providing safety then it is possible to secure safety prior to accident. Furthermore at such time mistake of the debtor can not become a factor. For this reason this line of thinking has the following merits: (1) In comparison with constitution of malfeasance default of an obligation has long prescription. It seems that such fact was a motivation for saving obligation for safety consideration by making it fall under the principle of faith. (2) Default of an obligation is not an obligation for ordinary attention which is cause of malfeasance but it takes up issue with obligation for attention required for performance. Game organization, sponsor and spectators etc. shares certain sense of identity and are demanded to have manners. As method for evaluation of such relationship of faith it may be possible to impose a special kind of obligation for attention and it will be close to constitution of default of an obligation. (3) Imposing obligation for provision clarifies that such responsibility belongs to game organizations promoting sports to which anyone can participates or to national or public organizations, sponsor, schools which induced such sports as a part of its educational programs, installer who made people use it as leisure facility or person in charge for its management. (4) It is also applicable to umpires, players or spectators who use field of sports. It is possible to reflect reality whereby these people specifically relate themselves to sports. In consequence it will be possible to make people feel the necessity of expanding the principals of sports from 'doers' to 'watchers.' (5) The obligation of provision is an obligation under the principle of faith therefore mutual negotiation may be expected to clarify such fact. It may be also evaluated by effectuation of users' self-determining right. 2. If the above mentioned structure is provided then, although it is limited to sports, students who are subjects of instruction, seminar attendants, and furthermore players who finished games may be obligated to bear responsibility for safety consideration under the principle of faith. Accordingly level of relief for considerable number of victims may be increased as cases of treating even borrowed materials as default of obligation being expanded. 3. As scope of responsibility becomes more clearer it will be possible to prevent disputes while securing more safety as rules and regulations become more clearly enacted or new contract is signed or existing contract is revised.

Twelve-year-old, catrated male, weighting 8 kg, Miniature Schnauzer dog was referred to the Veterinary Medical Teaching Hospital of Chungnam National University with history of depression. Result of blood analysis revealed anemia, thrombocytopenia, azotemia, elevated ALP, ALT and CK. On the radiographic examination, splenomegaly and loss of abdominal serosal detail were observed. Abdominal ultrasonography showed rounded mass of spleen and liver, ascites were observed. Splenectomy was performed and found that splentic tail had been ruptured and two samples from nodules on liver were obtained for histopathology. The result of biopsy revealed that hemangiosarcoma of spleen metastasized to the liver. Carboplatin was chosen as the patient had congestive heart failture. During chemotherapy hemangiosarcoma was metastasized into peritoneum and abdominal cavity. Intraperitoneal chemotherapy was preceded at this moment. After 99 days of initial visit, patient was euthanized due to severe anemia and thrombocytopenia.
