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).

재발 또는 불응성 비호즈킨 림프종 환자에서 CDME 구제항암화학요법 후 고용량 항암화학요법 및 자가말초혈액 조혈모세포이식의 효과

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.

Ti and Ti alloys are used in the dental field because of its high strength-to-density ratio, good fracture properties, corrosion resistance, and excellent biocompatibility. Corrosion characteristics of the cast pure Ti, Ti-6Al-4V, Ti-5Al-2.5Sn, have been investigated in 1% NaCl solution (37℃) and 40% CaCl₂solution (room-temperature) by means of Potentiodynamic polarization method. Corrosion potentials and corrosion current density of Ti alloys were compared to the Co-Cr alloy. The results are as follows: 1. The corrosion resistance of Ti-5Al-2.5Sn alloy was higher than pure Ti, Ti-6Al-4V alloy, Co-Cr alloy in the 37℃, 1% NaCl solution. But in the 40% CaCl₂solution(room-temperature), the corrosion resistance decreases in the order of Ti-6Al-4V, pure Ti, Ti-5Al-2.5Sn alloy. 2. The corrosion product (Ti₂O₂Cl₄) was formed on the corroded surface of Ti alloys in the 1% NaCl and 40% CaCl₂solution.

Objective : To investgate patterns of serial serum interleukin-6(IL-6) concentrations after initial successful cardiopulmonary resuscitation, and to access differences in serum IL-6 concentrations in patients with Cerebral Performance Category(CPC, 1-2) and CPC(3-5) at the 5th day after cardiacpulmonary resuscitation(CPR). Methods : We studied prospectively 12 patients with spontaneous circulation after cardiopulmonary resuscitation. Venous blood samples were taken 2, 4, 12, 24, 48 and 72 hours after restoration of spontaneous circulation to measure serum IL-6 levels by the enzyme-linked immunosorbent assay. Results : Serum IL-6 concentrations in the severe neurolgically disabled group(CPC, 3-5) were significantly increased at 2, 24 and 48 hours after restoration of spontaneous circulation compared with the less neurolgically disabled group. Also, serum IL-6 concentrations in the severe neurolgic disabled group showed dual peak at 4 and 24 hours. Conclusion : Our study demonstrates significant increase of serum IL-6 in patients with CPC(3-5) after successful cardiopulmonary resuscitation and the significant correlation between early increase of serum IL-6 and poor neurologic outcome. It suggests that early increase of serum IL-6 can be used as a prognostic marker after successful cardiopulmonary resuscitation.

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.

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.

교과교육의 내용과 방법

박형규 전주교육대학교 1995 論文集 Vol.32 No.-

The contents and method of the subject matter education have some close relationship mutually in achieving the education purposes. There are two opinions in such relationship : one is the opinion that two factors in education "process and result" have some "factual relationship", the other is the opinion that the two have "logical theoretic relationship". The two opinions can be briefly summarized as follows: 1. Dewey, Tyler, etc., insisted that the two are "factually related" 2. Ryle, Oakeshott, etc., insisted that the two are "logically related" In case of "factually related", the two factors are connected with the thinking process of the inner side of the learner and the thinking objects of the out side of the learner, and they are also separated each other into the thinking process and result and they are also connected "before" and "after" in time sequence. The process means the psychological process (knowledge as a process) in the inside of the learner and the result means the products of the thinking process (knowledge as a result) In case of "logically related", the two factors are not connected in time sequence and also they are no longer the thinking process of the inner part of the learner and thinking objects of the outer part of the learner. They are connected in the concrete educational situation in the relationship of "the inside and outside of the educational contents, they are also supposed to exist simultaneously in time sequence. In case of "factually related", the two are a different one each other. Therefore, we can develop some system of the methods to combine the two factors. But in case of "logically related", the system of the methods to combine the two comes to be different because "the process and result" of education exist simultaneously in time sequence and process and result are taught together in the same time. Dewey's opinion is that the "experience" includes the "process and result" of education. In other words, he insists the "process" exists in the contents of education. His opinion is a monism to integrate the contents and method of education. He thinks that the two "process and result" are operating each other in the "factually related state" to achieve the educational purposes and such thinking of his leads to the so called "general method-5 stages of thinking" which urges the systemization of the educational method. Tyler systemized the general procedure of education into a methodology to combine "factually" knowledge as a result (contents) and "psychological process of the inner side of the learner (Behavior) (Tyler, Basic Principles of Curriculum and Instruction, 1949). His methodology means the process to realize "factual combination" of the "contents and behavior" confirming the related factors in education which are connected with the "contents and methods" or the "process and results". Ryle insists that the "prepositional knowledge" and "procedural knowledge" are "logically related" each other and that they are in connection with the "inner side" and "outer side" or "bottom" and "surface" of knowledge. In other words the "process" and "result" of education, or "knowledge as the educational contents" and "thinking method" are also "logically related". According to his opinion, the "prepositional knowledge" and "procedural knowledge" can not be reduced to one because the two are "logically" divided each other. Oakeshott insists that the "technical knowledge" and "practical knowledge" are related each other not "factually" but "conceptually (logically)". The former can be taught by using of books and also can appear as a form of proposition but the latter can not be closed up to a form of proposition. He divided conceptually (not factually) the cultural inheritance into "information and judging". The former can appear as some facts or products of intellectual operation and the latter can not be presented as an item and we can not memorize it. His opinion is that we can teach the information by means of "instructing" and judging by means of "imparting". The "instructing" and "imparting" are also divided not "factually" but "logically" and they always operates themselves not one by one but together.

불안(각성)-경기수행 관계 이론에 대한 비판적 접근

Relationship between arousal and athletic performance has been of central importance throughout the history of sportpsychology. Because these variables such as stress, arousal, and anxiety are associated with athletic performance. Therefore, many psychologiests referred to the arousal(anxiety)-performance relationship. Then, since the later 1990s, most sport psychologists have emphasized the nation that an optimal level of arousal is associated with best performance. Accordingly, the drive theory and inverted-U hypothesis have become a stable principle in both the academic and professional sport psychology literature. In recent years, however, most sport psychologists have emphasized the nation that anxiety is associated with best performance. According to the these current research status and directions, purpose of this study was focused on critical understanding and application about the arousal-anxiety-athletic performance relationship theories. Results of this study are as follows : First, many of the earlier theories have examined the arousal construct, whereas more recent theories were developed based on anxiety construct. Two relatively early theories that were proposed and tested in the sport and motor performance context were the drive theory and the inverted-U hypothesis. More recently, however, + additional theories have been advanced. That is, these include Hanins optimal zones of arousal hypothesis, multidimensional theory of anxiety, catastrophe theory,reversal theory, and so forth. Second, terms such as arousal, stress, drive, attention, activation, motivation, alertness, and anxiety have been used interchangebly, although numerous theoretical distinctions have been made among them. Accordingly We must resolve the inconsistent use of these-related terminology. Third, in general, internal reaction phenomena of human such as stress, anxiety, and emotion could be explained by arousal reactation. Becase these reactions are phenomena for maintenance of athletes' internal ho- meostasis. So, these reaction mechanisms must be deemed the same context as a- rousal phenomenon. In the results, we must try to control about athlete's emotional-physiolocal- psychological phenomenon and sports competition conditions in use of these theories.
