Ceramic femoral heads in the total hip replacement have been developed to reduce the polyethylene liner wear. Alumina and zirconia (3Y-TZP) are using in clinical application worldwide and there are many good test reports. However, alumina has a risk of catastrophic failure, and zirconia has the low temperature degradation in spite of enhanced fracture toughness. Recently, novel zirconia/alumina composite having low temperature degradation-free character and high fracture tough . was developed and it leads the lower wear 3f polyethylene than alumina and zirconia. In the present study, in order to optimise the microstructure of low temperature degradation (LTD)-free zirconia/alumina composite for the best wear resistance of polyethylene, various compositions of (LTD)-free zirconia/alumina composites were fabricated, and the sliding wear of UHMWPE against these novel composites were examined and compared with that against alumina and zirconia ceramics used for total hip joint heads.

This study was clinically performed with the 73 outpatients of urticaria who had visited the Dept. of Dermartology, Oriental Medical Hospital, Dong-eui University from January 1st 2000 to June 30th 2003. They have all taken the oriental herb medicine as Sungmagalguntanggamibang(SGT, 升麻葛根湯加味方) more than 1 time. Urticaria is a common disease and a well known reaction pattern of the skin charaterized by erythema, wheals and edema, that is the results of various causes. Urticaria is classified into acute or chronic type. The etilogy of acute uricaria has been determined in many cases, but the cause of chronic urticaria has been determined in 10$\%$ to 20$\%$ of cases. Character of chronic type urticaria is recurrent pruritus and erythematous skin disease by stimulating factor. Through checking up the present patient state, we verified the effect of SGT in various ways. The results were summarized as follows; 1. An increase of taking a medicine(SGT) and attending a hospital in number let down repeated urticaria occurence. 2. SGT is more effective when the symptoms with the severe pruritic wheals are spread on the whole body in daily occurrence. 3. In urticaria treatment method, gradually reducing a western medicine and going side by side SGT, that is good at symptoms improvement. 4. Etiology of urticaria is classified into intestine-stomach accumulated heat by indigestion(食滯腸胃積熱), wind-moisture(風濕), wind-heat(風熱) etc. The SGT is available in the order of frequency of use.

The Dutch construction industry has introduced a compulsory preemployment medical examination (PE-ME). Best-evidence contents related to specific job demands are, however, lacking and need to be gathered. After the identification of job demands and health problems in the construction industry (systematic literature search and expert meeting), specific job demands and related requirements were defined and instruments proposed. Finally, a work ability assessment was linked to the instruments' outcomes, resulting in the modular character of the developed PE-ME. Twenty-two specific job demands for all Dutch construction jobs were identified, including kneeling/squatting, working under time pressure, and exposure to hazardous substances. The next step was proposing self-report questions, screening questionnaires, clinical tests, and/or performance-based tests, leading to a work ability judgment. "Lifting/carrying" is described as an example. The new modular PE-ME enables a job-specific assessment of work ability to be made for more than 100 jobs in the Dutch construction industry.

Intuition is an abstract concept which is most often thought of as a nonrational, nonscientific mode of thought. However, since there are so many amorphous definitions of intuition that it seems important to clarify the meaning of this concept. Therefore, this study use the process of Walker & Avant’s concept analysis to define of the concept of intuition Attributes of intuition were defined as 1) Knowledge of truth that is difficult to explicate ; 2) A type of immediate knowing ; 3) Knowlwdge without reasining analysis ; 4) Knowledge that is attained based on virtue character which integrates all matter and is not attained through individual experience. Antecedents of intuition consists of 1) as ground for knowledge or truth that is not availables to trace through the analytic procedures ; & 2) the flow of Ki which unites human beings and the universe. Consequences of intuition events or incidents occuring as a result of the concept consist of verification of the truth though analytic procedures and application of knowledge in both theoretical and practical ways. To develop intuitive ability, as an educator should not only make studies in recognizine, analysing and teaching concepts related to logical, rational decision making but should also recognize and teach concepts related to intuitive components of making decisions in clinical practice and classroom learning as well.

Purpose: To evaluate RBM surface implant which has its good character like that good initial stability, early bone formation. Material and Methods: In this study fixures have divided in 2 group: Machined(Group I), RBM(Group II). Total 10 fixtures were implanted on rabbit which sacrificed on week 2 and week 4 for the histological specimens. By these specimens polarized microscopic view, micro CT view, ISQ value were measured, compared and analysed by each group to figure out the evidence that clinical use of RBM implant. Result: ISQ value had no significance differences between 2 groups, However in each group 4, 8 weeks had higher ISQ value than 2 weeks. In polarized microscope, calcification level was following: Group II, Group I. In micro CT, formation of cancellous bone level was following: Group II, Group I. Conclusion: RBM implant was the most excellent on the early bone formation and good initial stability.

The international government committee is progressing their agreements about intellectual property protection of traditional knowledge(TK), gene resource(GR), folklore(FL) in WIPO. It is in the course of selection with precedence of TK, GR, FL in WIPO, focused on discussions about listing of TK documents, standardization of DB construction, sharing and profit distribution of GR. We made some plans to deal with agreements in WIPO. These plans consist of 5 subjects which are investigation about intellectual property related laws and systems, study of examination and finding, construction of DB information, development of value evaluation system, development of industrialization system with TK, GR, We suggest preceding details about 5 subjects respectively. It is the character of this plan that patent information DB system of TK, GR is the axis. It is the most important thing in these plans to succeed that we have to have connections with expert groups in order parts and government officials, taking whole supports of government because our traditional medical related study basis is weak.

Background: Parkinson's disease (PD) is a neurodegenerative disorder that is the second most common disorder after Alzheimer's disease. PD includes both "motor" and "non-motor" symptoms, one of which is pain. The aim of this study was to investigate the clinical characteristics of pain in patients with PD. Methods: This cross-sectional study included 250 patients diagnosed with PD, 70% of which had mild to moderate PD (stages 2/3 of Hoehn and Yahr scale). The average age was 67.4 years, and the average duration since PD diagnosis was 7.1 years. Relevant data collected from PD patients were obtained from their personal medical history. Results: The prevalence of pain was found to be high (82%), with most patients (79.2%) relating their pain to PD. Disease duration was correlated with the frequency of intense pain (R: 0.393; P < 0.05). PD pain is most frequently perceived as an electrical current (64%), and two pain varieties were most prevalent (2.60 ± 0.63). Our findings confirm links between pain, its evolution over time, its multi-modal character, the wide variety of symptoms of PD, and the female sex. Conclusions: Our results demonstrated that the pain felt by PD patients is mainly felt as an electrical current, which contrasts with other studies where the pain is described as burning and itching. Our classification is innovative because it is based on anatomy, whereas those of other authors were based on syndromes.

In order to provide the methodology of researching constitutional theories, the original meaning and the source of the term, ti(體) and zhi(質) written in and other text were reviewed, and then components of constitution(體質) and some evaluative norms and prospect on constitutional theories were proposed. Ti(體) means body or 5 tissues or patterns of them and zhi(質) means quality in , so the temporary meaning of constitution was generally same with present one. But the temperament originated from Greek and Elizabethan era is thought that it corresponds with constitution, but it means generally body type and character and mental pathologic features. The fundamental requirements of constitutional theories are needed stability, creativity, clinical efficiency and reproductiveness for differentiating with classical diagnostics over the range of disease and aging of the subject. And heredity, universality and extensiveness were recommended as additional requirements for making level up the theories through long-term follow-up, and to evaluate these requirements detail items were proposed. More of these, weight rendering should be made respectively afterwards.

Vertebral deformity in hatchery-reared black sea bream (Acanthoparus schlegelii) fingerlings occurred. Deformed fish had a good appetite but no clinical signs were found except the vertebral abnormality and darkness around the dorsal skin of the deformed vertebra. As more than 90% of the hatchery-reared fish exhibited vertebral abnormality, the fingerlings could not be used for commercial seeds any more. No morphological change in the swim bladder was observed. Histopathological changes on the deformed vertebra, gill, liver, and spleen were observed to clarify the cause of the deformity. The vertebra were irregularly deformed upward with the shape of "V" in an alphabetic character causing the spinal cord and dorsal aorta suppressed. The diameters of the muscle fibers around the deformed vertebra, especially, in the dorsal part, were much smaller and more irregular than those in normal fish, and the gabs between the fiber bundles were enlarged. No evidence of inflammatory responses in the lateral musculature were found. On the basis of normal inflation of the swim bladder, cultural environments for growth of the fingerlings, and histopathological alterations in the muscle, vertebra and gills, it is suggested that high speed of water current in the culturing aquaria between 23 to 30 days after hatching was responsible for the development of vertebral abnormality.

The purpose of this paper is to develop simulations that can be used for virtual education in dentistry. The virtual education to be developed will be developed with clinical training and actual case data of tooth extraction. This development goal is to allow dental students to learn the necessary surgical techniques at the point of their choice, not going into the operating room, away from time, space, and physical limits. I want to develop content using VR. Oculus Rift HMD, Optical Based Outside-in Tracking System, Oculus Touch Motion Controller, and Headset as Input / Output Device. In this configuration, the optimization method is applied convergent, and when the operation of the VR contents is performed, the content data is extracted from the interaction analysis formed in the VR engine, and the data is processed by the content algorithm. It also computes events and dental operations generated within the 3D engine programming and generates corresponding events through data processing according to the input signal. The visualization information is output to the HMD using the rendering information. In addition, the operating room environment was constructed by studying lighting and material for actual operating room environment. We applied the ratio of actual space to virtual space and the ratio between character and actual person to create a spatial composition at a similar rate to actual space.
