After liberation of August 15, 1945, it is, in fact, true that our higher education system has been developed visibly, however the policy of the higher education in the meantime brought lots of mistakes, due to lack of consistency, rationality, and speciality on it and it is still going a dispute on quantity and quality of the higher education. The purpose of this research is to observe the higher educational policy during the period from liberation of the August 15 till now and to investigate political, social, educational background of those days in processing higher educational policies handled by ministry of education according to social changes, in the same time finding out how higher educational policies were developed in our country and to obtain some suggestion about future indication in view of new stage of historic turning point. After having made a general survey historically, changing of the policies were as follows: 1. The period of founding policy (August 15, l915-June 24, 1950) The open-door policy, which was originated by introducing the principle of democratic educations, had founded a lot of colleges. 2. The period of reconstructing policy (June 25, 1950-May 15, 1961) Even though our government devoted itself to reconstruct educational facilities and quality of higher education since Korean War broke out on June 25, 1950, the result brought only their expanded numerous facilities. 3. The period of controlling policy (May 16, 1961-September 9, 1971) A decline of quality in college education due to expanded numbers and irrational operation of college has brought the result to strengthen the controlling policy by constituting laws and regulations. 4. The period of reforming policy (September 10, 1971-the present) As a policy to get rid of a discrepancy of the higher education in structure for normarization of the education, it has been improved to reform their education. The policy of higher education in Korea, as stated above, had been changed: It is considered that the reformation activity will certainly be settled in the stable era, passing through the period of decade.

In the biofilteration process, the removal of turbidity, color, KMnO₄consumpion, NH₄^(+)-N and UV254 reached 98%, 95%, 70%, 85%, 79% respectively. The stable removal efficiency was obtained by the direct filteration after coagulant dosage, though the influent was muddy and highly polluted. The exhausted GAC was used as the media of biofilter, which obtained stable removal efficiency compared with the other medias such as GAC, ZEOCARBON. Effluent of sorptived THMs was not found after 45 days during filter run time. And the case of dual media filteration was prior to single media filteration in the headloss development and quality of effluent. In the case of the ozone dosage rate was determined the color of biofilteration in the AAWTS system. 1㎎/L ozone dosage was proper when the color was below 8 unit.

The inhibitive effect of monethanolamine, N-methylethanolamine and on carbon steel S.S.41 in the 3.5% NaCl solution has been studied using polarization test method. A significant retardation of corrosion rate was observed in the 3.5% NaCl solution containing the inhibitors. The adsorption characteristic of inhibitor was studied and the adsorption heat(???)was calculated by molecular interaction value f. The results obtained from polarization test method revealed that the efficiency of corrosion inhibition was effected by molecular interactions of adsorption complex on metal surface. Using Frumkin adsorption isotherm, which was most favorable isotherm to the experimental data, molecular interaction of adsorption(f) for MEA, and NMEA on carbon steel surface were calculated to be -8.77, and -8.25 Kcal/mole, respectively. From these results, the heat of adsorption were estimated to be 16.77 and 12.18Kcal/mole, respectively. From the activation energy values, it was known that mechanism of corrosion had been changed by the addition of corrosion inhibitors.

Recently, industry-university cooperation has become a popular topic in Korea, which has been proved as one of essential for the industrialization in advanced countries. However, the main leaders of technical innovation, universities, institutions, and enterprises have mostly been doing their researches independently rather than relying on the co-research for the technical innovation. Considering the current situations, Korean goverment should set up the policy that those leader of technical innovations be reorganized in systematical an institutional sense, which end up with the co-research for the technical innovation.. Otherwise, Korea can't jump into the industrially advanced nation in which most of economic problem, especially, the problem of international payment can be solved through the relative advantage of technology. Furthermore, there exist an unlimited competition in high technology and a severe protectionism of technology among countries after the appearance of WTO. In establishing the system of industry-university cooperation, government takes into account the facts that industry should be organized into export oriented structure and be restructured to maximization of autonomy and originality of enterprise, and that the collection of information of technology and science, deregulation, and tax benefit and financial support should be executed by government. Also, industry-university cooperation brings about the better results through the introduction of part-time work at company for the university student, which finally cultivate the high technology man power.

Demand of micro holes has been increased fast, especially in the area of inkjet nozzle, micro turbine and optical parts. However, the micro hole with 40㎛ exit diameter and aspect ratio of 10 has yet to be reported. In this study, an endeavor was made to manufacture the micro hole under over 40㎛ exit diameter at stainless steel plate with 40㎛ thickness. To accomplish the goal, the relationship between machining parameters and machined result was identified. It was found that the entrance clearance was proportional to the discharge power, when discharge energy was kept constant and resistance had to be as high as possible at the given condition to minimize the machining time. 40㎛ average diameter of the micro hole with over 10 aspect ratio was achieved under the condition of 60V, 680pF, 500Ω, 1.5㎛ and 1500rpm.

연구배경: 동일한 환자를 대상으로 조혈모세포이식 전 일반 병실에서의 관해유도 항암제치료 및 강화요법으로 인한 호중구감소 기간의 감염양상과 고용량 항암제치료 후 무균실에서의 조혈모세포이식 시 호중구감소 기간의 감염양상을 중심정맥관 관련 패혈증을 중심으로 비교 연구함으로써 효율적인 감염관리지침을 마련하고자 하였다. 대상 및 방법: 1999년 1월부터 2001년 7월까지 2년 7개월간 동아대학교병원 일반병실에서 악성혈액질환으로 항암제 치료를 받다가 조혈모세포이식을 시행받았던 22명을 대상으로 중심정맥관 관련 패혈증의 형태를 비교분석하였다. 결과: 대상 환자들의 일반병실과 무균실에서의 입원기간은 각각 32±13일, 33±19일, 호중구 감소기간은 15±12일, 17±18일, 호중구 감소기간의 발열 횟수는 14회, 14회로서 입원병실의 종류에 따른 차이는 없었다. 환자들의 중심정맥관 사용일수는 일반병실에서 29일(7~545일), 무균실에서 100.5일(25~606일)이었으며, 총 사용일수는 각각 1,515일, 3,250일로서 무균실에서의 중심정맥관 사용일수가 의미 있게 길었다(P=0.001). 중심정맥관 사용 일수에 대한 감염률은 각각 5.28/1,000일, 3.08/1,000일로서 일반병실에서 그 빈도가 높았으나 통계적 유의성은 보이지 않았다(P=0.141). 결론: 중심정맥관 삽입 후 일반병실에서 항암제 치료를 받던 환자가 조혈모세포이식을 위하여 무균실에 입원하는 경우, 중심정맥관을 교체하는 것이 감염관리를 위하여 바람직할 것으로 생각된다. Background: We compared the incidence of central venous catheter (CVC) related septicemia during neutropenic period in the same patient, which developed following chemotherapy for remission induction and consolidation, or hematopoietic stem cell transplantation (HSCT). Methods: We retrospectively reviewed the medical records and laboratory data of 22 patients with hematologic malignancies who received anticancer chemotherapy followed by HSCT at Dong-A University Hospital between January, 1999 and July, 2001. We investigated the duration of hospitalization, duration of neutropenic period, duration of catheterization, microbiologically documented organisms and incidence of CVC related septicemia. Results: The data in general ward (before HSCT) and laminar air flow room (after HSCT) were as follows: duration of hospitalization was 32±13 days and 33±19 days, duration of neutropenic period was 15±12 days and 17±18 days, median duration of catheterization was 29 days (7~545 days) and 100.5 days (25~606 days) (P=0.001), and incidence of CVC related septicemia was 5.28/1000 days and 3.08/1000 days, respectively. In the CVC related septicemia, the most common etiologic organism was coagulase negative staphylococcus. Conclusion: We suggest that the exchange of CVC before admission to laminar air flow room could decrease the incidence of CVC related septicemia in HSCT recipients.

The delivery of the proper care to the emergency dental patients is more important in the aspdect of community dental service. To attain such a purpose requires the sacred duty to the training of oral and maxillofacial surgeons. This is a retrospective study on the characteristics of dental injuries and diseases in emergency patients. Ths study was based on a series of 2,649 patients treated as dental emergency patients at K country hospital of medical college, from Jan. 1, 1993, to Dec. 31, 2000. The obtained results were as follows. The trauma(71.6%) was the most frequent cause in dental emergency patients, odontogenic infection and oral hemorrhage were next in order of frequency. The primary interdental wiring and transpalatal wiring were frequent proper methods with rubber drainage for prevention of hemorrhage and infection in the primary care of jaw fracture. The peak incidence(45.0%) about the infection group was occurred in the pulpitis of advanced dental caries, and common treatments were the medication of antibiotics & anagesics and I&D. In the dentoalveolar hemorrhage group, a major cause was postoperative hemorrhage(57.9%) and hemostasis was obtained by pressure dressing, suture and drainage of infected wound. About TMJ disorder group, the peak incidence was showed in the post-traumatic myofascial pain dysfunction syndrome and its primary care was medications(anagesics & sedatives). In the other groups, various irritable specific pains were complained, such as trigeminal neuralgia-form pain, acute stomatitis, chemical burn, terminal stage neuritis of head & nech cancer and their primary care methods were various individually. For the rapid and correct care of the emergency dental disease above, well-trained education should be presented in the intern and resident curriculum of oral & maxillofacial surgery.
