Bilateral cleft lip reconstruction can be performed in one-or two-stages. The choice depends on the surgeon's proficiency and experience. However the type and severity of the cleft must be considered. Complete or incomplete symmetric, bilateral clefts in which the premaxilla is within the alveolar arch or slightly protruded can be successfully treated with simultaneous lip reconstruction on both sides. There are some advantages that one-stage lip reconstruction facilitates creation of a symmetric and balanced lip, retraction of protruding premaxilla and the parent's psychologic satisfaction. However, there are some disadvantages such as micrognathia of the upper jaw by severe scar formation and poor adaptation of flap margins by severe tension. The surgeon must be able to judge and exploit the advantages offered by one-stage approach. We present the case report of one-stage reconstruction of primary bilateral cleft lip with literature reviews.

Despite the current accomplishments with the repair of cleft lips, the surgical management of the nasal deformity remains a functional and aesthetic dilemma for patients, their families, and reconstructive surgeons. Recent improvements in the understanding and technical execution of te primary cleft lip repair have significantly reduced secondary sequelae and the consequent need for secondary surgical correction. But, secondary surgical corrections are necessary according to numerous factors. Such factors include the secondary surgical corrections are necessary according to numerous factors. Such factors include the severity of the initial deformity, the surgical plan, precision of execution of the primary repair, and success of the postoperative management. We preformed the secondary correction of cleft lip and palate in 11 patients via various methods. In conclusion, primary repair of cleft lip and palate patients is the most important to prevent the secondary deformities, and most of cleft lip and palate with secondary deformities must be treated with combined cheiloplasty and rhinoplasty.

In many respects, the reaction of people to foreign models appearing in advertisements may be different from that to domestic models. The author classified the reaction into three components of cognitive, affective, and behavioral dimensions and explained this difference in term of the quality of the product advertised, by model's race, and by subjects' level of prejudice. A 2×2 factorial experimental design was used for the purpose of finding causal relationships between two out of three independent variables and each dependent. variable described above, and Analysis of Variance (ANOVA) was used to analyze the data. The result of this study is summarized as follows. Within groups of same level of prejudice, model's race and the quality of the. product did not influence the affectiue and behavioral aspects of peoples elvaluations. on advertisements. But a person's cognition was significantly affected by the quality of the product. When foreign models were used, a person's level of prejudice and the quality of the product had no significant effects on the other dimensions. But the quality of the product seemed to influence people's evaluation on the cognitive qualities of an advertisements.

Objective : There are controversies in pnmmg technique of rocuronium whether it can or can't shorten the onset time. We want to compare the effects of two different priming doses and intervals of rocuronium. Materials and Methods : After giving propofol, 50 patients were randomly assigned to 5 groups. Group I received a placebo, followed 3 min later by rocuronium 0.6 mg/kg. Priming doses and intervals of Group II, Ill, N, V were 0.06 rng/kg and 2 min, 0.12 mg/kg and 2 min, 0.06 rug/kg and 3 min, 0.12 mg/kg and 3 min, respectively. Total dose of rocuronium was 0.6mg/kg. Train of four (TOF) count or ratio and 1st twitch height of TOF (T1) were monitored with 15 secondsintervals. TOF ratio of each groups just before bolus injection, duration for TOF count to reach zero and duration for Tl to reach 95% depression after bolus injection were compared. Results : Duration for TOF count to reach zero and duration for Tl to reach 95% depression after bolus injection were decreased in priming groups compared to Group 1 (P < 0.01) In group V, significant depression of TOF ratio just before bolus injection was seen (P < 0.05). Conclusion : Priming technique with rocuronium is effective method to shorten the onset of neuromuscular block. But priming dose of rocuronium itself could cause hypoxia and aspiration in awake patients and should be used carefully. Priming dose of rocuronium 0.06 mg/kg and 2 minutes interval maybe relatively safe method.

광천사문석광상 사문암은 총 연장 약 2,000m, 최대폭 약 30m의 렌즈상 내지 맥상으로 북북동 내지 북동방향에 따라 선캄브리아기의 월현리층을 관입하였는데, 사문암과 직접 접한 암석은 각섬석편암이다. 광천사문암은 주로 50%이상의 사문석으로 구성되었으며 기원암의 잔류광물인 감람석, 휘석 및 각섬석이 소량 포함된다. 감람석과 휘석은 결정경계나 결정내 균열을 따라 사문석화되었다. 감람석으로부터 사문석화 할 때에는 MeO와 FeO값이 감소하였고 SiO₂값은 별 변화가 없다. 사문석 결정 주변의 망상조직으로 발달된 자철석은 사문석화과정에서 빠져나온 철로부터 형성된 것으로 해석된다. 한편, 휘석으로부터 사문석화 할 때에는 SiO₂값은 크게 감소하고, MgO 값은 약간 증가하였으나 FeO값은 약간 감소하였다. 광천사문암의 기원암은 더나이트와 휘석감람암 또는 해즈버자이트라고 해석되며, 이 기원암으로부터의 주사문석화작용은 광역변성작용에 의하여 이루어졌다고 해석된다. Serpentinites of Kwangcheon serpentine ore deposits occur mainly in Weolhyeon-riformation as NNE to NS trending lenticular to vein type body. They extend for about 2000m long and have maximum width of about 30m. Most country rocks very contacted with serpentinite are amphibole schists. Kwangcheon serpentinites are mainly composed of more than 50% serpentine, but partly have original minerals such as olivine, pyroxene and hornblende. Olivine and pyroxene were serpentinized along the crystal boundaries and/or cracks in the crystals. On the process from olivine to serpentine, MgO and FeO values are decreased and SiO₂values are nearly not changed. It is considered that mesh-texture magnetite around the serpentine crystals was formed from the iron which had been left out through this serpentinization process. But, on the process from pyroxene to serpentine, SiO₂values are much decreased, and MgO values are slightly increased and FeO values are slightly decreased. Also, it is considered that the original rocks of Kwangcheon serpentinites was mantle origin ultramafic rock such as dunite and, pyroxene peridotite or harzburzite, and main serpentinization of Kwangcheon serpentinites from these original rocks was formed by the regional metamorphism of greenschist to amphibolite facies.

The purpose of this study was to evaluate the efficacy of adding autogenous bone to the toothash-plaster mixture in the healing process of bone. Full-thickness round osseous defects with the diameter of 20mm were made at the calvarial bone of adult dogs (n=19) bilaterally, which were thought to be critical size defect. The right defects were repaired with the toothash-plaster mixture plus autogenous bone (compressed volume 0.3cc) and the left defects with only toothash-plaster mixture. At 2-, 4-, 8-, 12- and 20- week after implantation, dogs were sacrificed and evaluated the osseous healing of bony defects clinically, radiographically, and microscopically. The results were as follows : 1. At the clinical observation, the wound healed very well without any problem except severe swelling in the early period after operation. Slight depression was recognized at the both sides when the portions of cranial defect were palpated. 2. There were statistically significant differences between toothash-plaster mixture groups and autogenous bone added groups at the same period, and among the groups in the bone density of the digital radiograms (P<0.001).There was a tendency that bone density was increasing with time. 3. In light microscopic examination, new bone formation was more active in the autogenous bone added groups than toothash-plaster mixture groups at the early period after mplantation but there is little difference at 20-week after implantation. 4. In fluorescent microscopic examination, the fluorescent band could be observed at the area of active bone formation and the band was more distinct in the autogenous bone added groups then toothash-plaster mixture groups. 5. In transmitted electron microscopic examination, organelles such as rER, Golgi complex and secretory granule and osteoblast were observed. In summary higher volume ratio of autogenous bone is needed to improve the bone healing in that there is little difference between toothash-plaster mixture group and autogenous bone added group at the 20-week after implantation in spite of new bone formation was more active in the autogenous bone added groups than toothash-plaster mixture groups at the early period after operation.

Running title: Cases of anesthesia for extremely low birth weight infant. Extremely low birth weight infants (birth weight < 1000 g) are prone to various morbidities such as respiratory distress syndrome, intraventricular hemorrhage, periventricular leukomalacia, patent ductus arteriosus, necrotizing enterocolitis and retinopathy. To accomplish successful anesthetic management, many precautions must be continuously taken during the operation. First, inspired oxygen concentration should be adjusted to avoid oxygen toxicity. Second, body temperature must be maintained adequately. Third, hemodynamic parameters should be kept stable. We report 2 cases of successful anesthetic management for extremely low birth weight infant who underwent ligation of patent ductus arteriosus at the neonatal intensive care unit.

Microstructure and properties of cross-roll rolled and heat treated metastable TiNbSn alloy.

Jung, Taek-Kyun,Choi, Ho-Joon,Kim, Kyung-Taek,Shin, Young-Chul,Lee, Hyo-Soo,Lim, Sung-Chul,Kwon, Hyouk-Chon,Hanada, Shuji American Scientific Publishers 2014 Journal of nanoscience and nanotechnology Vol.14 No.10

<P>A (Ti-35mass%Nb)-4mass%Sn alloy was cross-roll rolled with a reduction ratio of 70% in which the roll axes are tilted by 5 degrees away from the transverse direction of the rolled sample and then aged at 250 degrees C for 2 h. Cross-roll rolling was found to increase yield strength and Young's modulus, simultaneously. Yield strength was higher in cross-roll rolled than in conventionally rolled at same reduction ratio. Yield and tensile strength further increased by a low temperature ageing by ψ precipitation hardening and microstructure refinement. Yield and tensile strength of the aged 70% cross-roll rolled sample were higher than those of the aged 70% conventionally rolled one.</P>
