1. 하순에 심한 self-mutilation wound를 야기한 Lesch-Nyhan Syndrome 환아에서 상하악 유전치에 치관부 절단 및 치수 절세술을 시행하여 치아에 의한 자해를 방지하였다. 2. 장치를 이용한 치료가 어려운 경우 발치가 고려되기도 하나 본 증례에서는 발치보다 보존적인 술식으로 만족할 만한 결과를 얻었다. Self-injurous behavior is defined as deliberate harm to one's own body without suicidal intent. It usually occurs as head banging or hitting, skin cutting, or finger biting and includes ocular, genital and oral self-mutilation. Lesch-Nyhan syndrome is a rate X-linked recessively inherited disorder, caused by complete absence of hypoxanthin-guanine phosphoribosyl transferase(HPRT) activity. Clinical presentation is characterized by mental retardation, chorea, athetosis, hyperuricemia, uricosuria and self-mutilating behavior. In these patients, the most typical feature is loss of tissue from biting themselves, even though they are not insensitive to pain. The dental management of self-mutilation includes treatment with appliances such as soft mouthgrard or lip bumper, extraction of all the teeth, and orthognathic surgery. We report a 25-month-old boy who was a known case of Lesch-Nyhan syndrome and presented with severe self-mutilation wound on his lower lip. Vital pulpectomy and coronal resection was done as a more conservative approach than extracting all primary anterior teeth. Due to maintaining the root portion of the teeth in the bone, it is expected that the normal growth of the alveolar bone will be achieved.

Pseudoaneurysms form when a hemorrhage or hematoma from the injured arterial wall is replaced with an fibrous vessel wall, which is dilated by subsequent pulsating pressure. Recently, we experienced a patient with a pulsatile preauricular mass, measuring about 1.5× 1.5 cm, sustained from blunt trauma by the baseball. The presumptive diagnosis of pseudoaneurysm of the superficial temporal artery was made by Doppler sonography. Under local anesthesia, the aneurysm was excised en bloc following ligation. We report the rare case with a review of literatures.

The effect of welding residual stress on the initiation and propagation of fatigue crack is investigated so as to study the fatigue behavior in welding residual stress field. Especially, the relation between welding residual stress and fatigue crack opening behavior is investigated and the redistribution of residual stress as a fatigue crack propagates is examined. Following results are obtained. 1) In case of the load range is constant, as the stress ratio is changing to 0.1, 0.33, 0.5 the propagation life is constant but the growth life decreases. And than, when maximum load or minimum load is constant, as the stress ratio increases the growth life and propagation life increase. 2) The fatigue crack propagations rate da/dN appears to accelerate when the stress intensity factor range ΔK is less than 15MPa-m^1/2. 3) The residual stress that is appeared by welding decreases after cutting. 4) Fatigue crack propagation ratio is affected by tensional and compressible residual stress at the initial time, but it's similar to the original in the more than 20mm of crack length.

1. Hypophosphatasia 는 골조직 및 치아조직의 비정상적인 석회화를 나타내는 대사장애로, 특징적구강내 소견 인 우치의 조기탈락 양상으로 치과에서 조기진단이 가능하다. 2. 본 증례에서 상악궁 확장을 동반한 의치 제작으로 심미적, 기능적으로 양호한 결과를 얻었으며, 영구치열기 까지 장기적 관찰 및 치료가 필요할 것으로 사료된다. hypophosphatasia is a rare metabolic disorder which manifests characteristics such as abnormal mineralization of bone and dental tissues, diminished serum and tissue alkline phosphatase, and increased urinary secretion of PEA. It ingerited as an autosomal recessive or dominant trait and occurs in all races. In general, hypophosphatasia can be classified in 4 subtypes which are the perinatal, infantile, childhood, adult type depending upon the age at presentation and severity. In young children with Hypophosphatasia the long bones show irregular defects, and the skull showes poor calcification. In older children with premature closure of the skull sutures there may ve multiple lucent area called gyral or convolutional markings, described as resimbling beaten copper, presumably resulting from increased intracranial pressure,Examination of the jaws reveals a generalized lucency of the maxilla and mandible, the cortical bone and lamina dura are thin, and the alveolar bone may be deficient. Clinical features of Hypophosphatasia imclude premature loss of deciduous teeth, especially incisors, hypoplasia of aplasia of root cementum, enamel hypoplasia, irregular calcification of dentin, large pulp chamber, and resorption of marginal alveolar bone and roots. Our report involves a patient with a chief complaint of early loss of both Mx. and Mn. deciduous ncisors. after conducting a through clinical and radiographic examination this patient was referred to pediatrics under the suspicion of hypophosphatasia, the diagnosis proved to be correct and successful results were accomplished through a denture made to improve esthetics and function.

The purpose of this study was to investigate the The effect of Treadmill Walking Conditions on Cardiovascular Function. Ten healthy females were participated in this experiment. Subjects walked on a comfortable walking speed(2.74km/h) under three conditions. Three conditions were : First, without a knee immobilized and crutches(normal) Second, with a low leg immobilized(cast), third, with a low leg immobililized and cruthes(cast and crutch). Ventilatory Volume, Oxygen Cost, Respiratory Exchange Ratio, Kcal, Ventilatory Equivalent were measured by Gas analyzer, FIR by Polar heart rate tester.. Results of this study were as follows : First, Ventilatory Volume of cast and crutch group increased as compared with normal group and cast group(p<0.01). Second, Oxygen Cost of cast and crutch group increased as compared with normal group and cast group(p<0.01) Third, In Respiratory Exchange Ratio and Ventilatory Equivalent, no significant differences existed among the three groups. Fourth, Kcal of cast and crutch group increased as compared with normal group and cast group in 15minutes(p<0.01), 18minutes(p<0.01), 21minutes(p<0.05), but in the other time, no significant differences existed among the three groups. As a results, Cardiovascular Function of knee immobilization and crutch group increased during level walking at comfortable walking speed(2.74km/h) as compared with knee immobilization group and normal group. Therefore, This fact must be considered during walking training and exercise.

Seeds의 Crystallinity가 Cordierite의 상변태에 미치는 영향

최태현,전병세,이성우 慶南大學校 附設 工業技術硏究所 1994 硏究論文集 Vol.12 No.-

고밀도이며 고순도인 cordierite를 제조하기 위하여 solution sol-gel법과 α-cordierite의 seeding을 이용하였다. 시료를 분말과 monolith로 나누어 실험을 행하여 seed의 품질이 cordierite의 μ-type에서 α-type로의 상변태와 밀도에 관해서 각각 어떠한 영향을 미치는가에 대해서 알아보았다. 연구결과, 1000℃에서 합성한 seed용 분말보다 1300℃에서 합성한 seed용 분말이 더 α-cordierite 결정에 접근되어 있었고, 1300℃에서 합성한 seed를 첨가한 분말이 여러 범위의 온도에서 α-cordierite결정으로 가장 잘 발달하였으며, monolith의 경우 역시 1300℃에서 합성한 seed를 첨가한 것이 높은 밀도를 가지는 것으로 나타났다. 그러므로 cordierite의 homogeneity와 밀도는 첨가하는 seed의 crystallinity에 크게 좌우된다고 하겠다. Solution sol-gel(SSG) method and seeding were used to fabricate homogenious α-cordierite with high purity. The cordierite powders prepared by SSG and heat-treating at various temperature ranging 1000-1300℃ were added in the mixed or reacted with solution for seeding. Seed powder synthesized at 1300℃ was well developed to α-cordierite rather than any other seed powders at below 1300℃ and the quantity of α-phase was highest in the powder heat-treated at 1300℃ which had been added by seeding at 1300℃. The densities of all the monoliths were high because of existense of other phases like spinel. Therefore, the homogenity of resultant oxides depends on the crystallinity of seed.
