This study includes an empirical analysis of utilization of strategic management with hospital information system and a policy implication on hospital management. The purposes of this study are to analyze the effects of strategic information and implementation on the major performance factors. For this study. the materials used are mailing survey data of 65 hospitals and related literature was reviewed. Crosstabulation and multiple response analysis were made to find the frequencies by groups. ANOVA and multiple regression analysis were adopted to examine the differences and the relationship between variables involved. The major findings are as follow: 1. Internal information needed for strategic management focuses on the patients' data and the ones of services being delivered. Using portion of financial indices also ranked 2nd by respondents. but financial analysis was not performed frequently. 2. The Effects of strategic information on the hospital management environment were the most in hospital planning and hospital administration and medical support tasks. Ane the effects of assessment of the external factors and rapidity and accuracy of decision making, however. were relatively low. 3. The more computer system group satisfy planning group on the material requested by planning group. the more effects of cost reduction and service promotion have favorable results. Besides. the more computer education and PR are performed. the more efficiencies of hospital management have favorable results. In result of more exploration, the relationship of between computer education and PR item and satisfaction level of planning group on requested material and cost reduction effects was statistically significant. Of the above results. there are favorable effects on the major performance factors. However. there are few results of being performed on systematic strategic planning, action and management. With regard to hospital management information system, there are many challenges in the future when applying strategic management methods. Hospital executives must begin to use information system strategically for survival and growth in the 2000s.

The zygomatic bone occupies a prominent and important position in the facial skeleton. The zygoma forms a significant portion of the floor, lateral wall of the orbit and the zygomatic arch, otherwise known as the malar eminence, which plays a key role in the determination of facial morphology. It is structure where the masseter muscle is inserted on the ventral part of the arch, and participates in the formation of the face, giving it a prominence of each cheek and a round outline. It is prone to fracture due to its bony prominence. Between the zygomatic arch and the skull, the coronoid process of the mandible moves freely when the mouth is opened and closed. A fracture which depresses this arch generally implicates a partial or total obstruction of the movement of the condyle and of the coronoid process of the mandible, changing the opening and closed. A fracture which depresses this arch generally implicates a partial or total obstruction of the movement of the condyle and of the coronoid process of the mandible, changing the opening and closure of the mouth. these fractures may also be responsible for the so called false ankylosis of the TMJ. The author describes a simple technique for reducing zygomatic arch which is displaced medially and impinges on the coronoid process. The technique is concerning the alevation of depressed fracture of zygomatic arch using the foley catheter. I think that this technique would be avilable for out patient department under local anesthesia and intravenous conscious sedation. Also, it would be used in postoperative stabilization of reduced comminuted zygomatic arch fracture and used in reduction malarplasty.

Porter의 경쟁구조분석, PLC 분석, 시장창출 메카니즘 분석, 그리고 시장 기회 및 위협요인 분석을 통하여 국내 키토산 산업을 조망하였다. 경쟁구조에서 특징적인 부분은 원료공급 비즈니스가 수산업에 해당되기 때문에, 원료수급이 매우 불안정하다는 점과, 주요 응용분야인 건강보조식품 분야의 PLC가 3~4년을 넘기기 어렵기 때문에 대체위협이 항상 존재한다는 점이다. 또한, 다양한 기회요인과 위협요인이 대두되고 있으나, 현 상황에서는 위협요인이 크게 부각되고 있는 상황이며, 기술적 성숙이전에 bubble 시장이 과도하게 형성되어, 이후에, 기술적 제약요인(constraints)으로 해결되지 못할 경우 급격한 시장규모의 감소현상으로 이어질 소지가 있다. 이에 따라, 고품질의 키토산 유도체 등의 개발 및 용도 확대가 향후 키토산 시장의 지속적 성장을 가능하게 하는 중요한 요소로 작용할 것이다. Chitosan industry was analyzed through Porter's 5P's, PLC, formation mechanism, drivers and constraints of the market. 5P's analysis reveals that unstability in supplying raw material and strong power of substitutes exist. Short PLC of 3-4 years, in functional food market, is also played as one of the severe market constraints. In addition, the Korean chitosan market was sensationally expended despite lace of technological breakthrough, so, to achieve sustainable market growth, the development of derivatives and new application fields are needed.

Racemate is same chemical property and physical property, hard to separate by general method. In this study, separated racemate to use MIP(Molecularly Imprinted Polymeric) Membranes by simple process and high selectivity. The functional monomers were co-polymerised in the presence of a target/imprint molecules, which acts as a molecular template. Subsequent removal of the template molecules left behind functionalised cavities that are able to recognize the template molecules. Composite two types membrane imprinted with L-tryptophane(L-Trp) were developed using uv-irradiated polymerization. As a result, membranes covered with a thin film of imprinted polymer selective to L-Trp were obtained with different degrees of modification.

Eigenvalue analysis of vibration mode and an analysis by frequency response among the methods of predicting gear noise are related with transmitting sound of vibration. In this study we intended to reduce the vibration noise of differential gear by reducing torque fluctuation of drive pinion shaft which causes vibration noise of differential gear in rear wheel drive vehicles. For this we developed multi-degree of freedom analysis model in which mass moment of inertia and torsional spring combined and we examined the influence of torsional vibration of driveline elements by performing forced vibration analysis of engine excitation torque. We studied the methods for reducing torsional vibration of driveline according to the design factor of propeller shaft and examined the effect reducing vibration in differential gear by flexible coupling.

It is known that the periodontal disease is caused by infection of inner oral bacteria as a suffering disease to human mankind for a long time. It can make the various clinical symptoms such as gingiva, bleeding, formation of periodontal pocket, loss of attached gingiva, collapse of alveolar bone and halitosis, and is known to the major contributor of loss of teeth. This study investigated the growth restraint effect of Camellia sinensis and Casia tora. As a result of study, the minimum restraint concentration of standard microbe on F. nucleatum for extracts from C. sinensis showed 2.5, 0.63 and 1.25 mg/ml, respectively and minimum restraint concentration of clinical separation microbe on F. nucleatum for extracts from C. sinensis showed 2.5 and 5.0 mg/ml. The minimum restraint concentration of standard microbe and clinical separation microbe, respectively. Meanwhile, the minimum restraint concentration of standard microbe and clinical separation microbe on F. nucleatum for extracts from C. tora showed 2.5 and 2.5-5.0 mg/ml, respectively. The minimum restraint concentration of standard microbe and clinical separation microbe for P. intermedia, P. nigrescens, P. gingivalis, and P. endodontalis showed above 5.0 mg/ml for standard microbe and above 5.0 mg/ml for clinical separation microbe, respectively. As a result of investigating the cell toxicity for each extracts, extracts from C. sinensis does not showed the toxicity for the cell below the concentration of 2.5 mg/ml, but it showed toxicity for the cell above concentration of 2.5 mg/ml and it decreased the existence ratio for the cell. Meanwhile, in the case of C. tora, it increased the multiplication ratio below the concentration of 1.25 mg/ml compared to the subject group and it decreased gradually the multiplication ratio that the growth ratio for the cell is increased better than subject group. As a result of this study, extracts from C. sinensis was more effect on the growth restraint effect against periodontopathogens than extracts from C. tora and is proven that it is possible for use as a oral mouthrinsing liquids in the near future. On the basis of results of this study, it is judged that the study for reaction mechanism and discrete clinical test for implementation should be needed.

Dental caries is a chronic disease that causes the destruction of tooth structure by the interaction of plaque bacteria, food debris, and saliva. There has been attempts to induce remineralization by supersaturating the intra-oral environment around the surface enamel, where there is incipient caries. In this study, supersaturated remineralized solution "R" was applied to specimens with incipient enamel caries, and the quantitative ananlysis of remineralization was evaluated using microradiography. Thirty subjects volunteered to participate in this study. Removable appliances were constructed for the subjects. and the enamel specimen with incipient caries were embedded in the appliances. The subjects wore the intra-oral appliance for 15 days except while eating and sleeping. The removable appliance were soaked in supersaturated solution "R", saline, or Senstime® to expose the specimen to those solutions three times a day, 5 minutes each time. After 15 days, microradiography was retaken to compare and evaluate remineralization. The results were as the following: 1. The ratio of remineralized area to demineralized area was significantly higher in the supersaturated solution "R" and Senstime® than in the saline (p<0.05) 2. Remineralization in the supersaturated buffer solution "R" occurred in the significantly deeper parts of the tooth, compared to the Senstime® group containing high concentration of fluoride.(p<0.05) As in the above results, the remineralization effect of remineralized buffer solution "R" on incipient enamel caries has been proven. For clinical utilization, further studies on soft tissue reaction and the effect on dentin and cementum are necessary. In conclusion compared to commercially available fluoride solution, remineralization solution "R" showed better remineralization effect on early enamel caries lesion. so it is considered as effecient solution for clinical application

In order to study the effects of Dalsaengsan, reputed to be the effective for the remedy and treatment of hard labor, experiments regarding the antiabortive effect of Dalsaengsan on the pregnant rats and the effect of it on the uterine smooth muscle strips of nonpregnant rats were carried out. The results were as follows 1. The drug administered on the uterine muscle strips of nonpregnant rats caused the effect of uterine relaxation in proportion to concentration of the drug. 2. The drug administered on the uterine contraction induced by oxytocin or prostaglandin F_(2α) of nonpregnant rats caused the effect of uterine relaxation in proportion to concentration of the drug. 3. The drug administered on the antiabortive effect when the dosage of the drug was 640 ㎎/㎏. 4. The effect of extracted powder and mixture of each extracted powder was nearly the same on the relaxation effect of the drug on the uterine muscle strips of the nonpregnant rats, but the effect of the former was better than that of the latter on the antiabortive effect.
