Aluminum hydroxide gels were formed from aluminum salts by precipitation method. These gels were aged and calcined to get γ- alumina. The effects of aging condition for aluminum hydroxide gels on the physical properties of γ- alumina were tested varying aging pH, time and temperature using aluminum sulfate as starting materials. The effect of starting materials were tested using aluminum sulfate, nitrate and chloride salts. Activated alumina prepared from Boehmite aged under the condition of pH 11 and 170℃ showed high surface area and large pore volume. Aging time above 1 day showed a little effect on the properties of activated alumina. Optimum aluminum salt concentration for high surface area and large pore volume was 4 wt%.

With increase of traffic accidents, the otologic problems including facial palsy with skull fracture are more concerned. This paper is report our experiences with 16 cases of traumatic facial nerve palsy which have been employed transmastoid supralabyrinthine facial nerve decompression during last four years. The results are as follows: 1. Of the 16 patients, 13 patients(81.3%) were men and 3 patients (18.8%) were women. And sex ratio was 1.4:1 (male predominent). 2. In fracture type, longitudinal fracture was 10 cases (62.5%), transverse fracture was 1 case(6.3%) and mixed fracture was 2 cases(12.5%). 3. Cerebral contusion was combined in 8 cases(50%) and facial bone fracture was combined in 6 cases(37.55). Because of these combined lesions, otologic diagnoses and treatment was delayed. 4. The most common physical finding on clinical examination were a bloody otorrhea(75%) and hearing impairment(75%). 5. In frequency of lesion in facial nerve, tympanic segment(35.7%) was the most common site, followed by geniculate ganglion(14.3%). Suggested mechanisms in facial palsy were nerve compression(57.1%), granulation tissue and congestion. 6. There were improvment of House-Brackmann grades in 13 cases after decompression. 7. Incudostapedial separation was found in 4 cases and incus fracture was found in 2 cases. Hearing improvement was found in 3 cases being ossiculoplasty.

Background The olive founder (Paralichthys olivaceus) is a saltwater fsh, which is valuable to the economy. The olive founder strives to adapt to environmental stressors through physiological, biochemical, and transcriptional responses. The rise in water temperature threatens the growth, development, reproduction, and survival of olive founder. Each organ in the olive founder can diferentially respond to heat stress. Objectives The purpose of this study is to investigate organ-specifc transcriptional changes in olive founder tissues during heat stress. Methods In this study, transcriptome dynamics of the gill, liver, and muscle of olive founder to acute or chronic heat stress were investigated. Results Principal component analysis plotting revealed that the transcriptome of each organ is quite separated. K-means clustering, gene ontology, and Kyoto Encyclopedia of Genes and Genomes pathway analysis showed the diferential transcriptome responses of each organ to heat stress. Heat stress commonly afects the pathways involved in the correct protein folding, DNA repair, and cell cycle. Conclusion Our results may provide a valuable molecular basis of heat acclimation in fshes.

신호처리법으로 현재 많이 사용되고 있는 푸리에 변환은 신호의 주파수 성분이 사간에 따라 어떻게 변화하는지를 표현하지 못한다. 따라서 최근 이와 같은 푸리에 변환의 단점을 보완하여, 신호의 시간과 주파수에 대한 정보를 동시에 표현할 수 있는 시간-주파수 해석법들이 개발되었다. 본 연구에서는 음향방출을 이용하여 복합재료의 주요 발생원으로 알려져 있는 기지균열, 섬유분리, 섬유파괴 및 층간분리 등과 같은 파괴기구를 해석하였다. 각각의 파괴특성이 나타나도록 시험편을 제작하여 인장시험 시 검출된 음향방출신호의 시간-주파수 해석을 통해 전체 파괴기구의 특징을 분석하였다. Fourier transform has been one of the most common tools to study the frequency characteristics of signals. With the Fourier transform alone, however, it is difficult to tell whether signal's frequency contents evolve in time or not. Except for a few special cases, the frequency contents of most signals encountered in the real world change with time. Time-frequency analysis methods are developed recently to overcome the drawbacks of Fourier transform, which can represent the information of signals in time and frequency at the same time. In this study, damage process of cross-ply carbon fiber reinforced plastic (CFRP) under monotonic tensile loading was characterized by acoustic emission. Different kinds of CFRP specimens were used to determine the characteristics of AE signals. Time-frequency analysis methods were employed for the analysis of fracture mechanisms in CFRP such as matrix cracking, debonding, fiber fracture and delamination.

CdS thin film was fabricated by chemical bath deposition method and polycrystallined by the proper heat treatment. The physical properties of the amorphous and polycrystal of CdS thin film were observed and calculated by measuring the X-ray diffraction patterns, optical absorption, transmission and photoconductivity. From the present experiments, we obtained the energy band gap of the CdS polycrystal thin film to be 2.42eV and the In donor impurity level to be 0.025 eV below the conduction band : Another result was to be a_o=4.13Å and c_o=6.75Å for lattice constants of the hexagonal structure. Also, we attempted it to find the possibility of the application to photosensor. To apply cds this film to the photosensor more sufficiently, further experiments are required to accumulate data on such problems.

상완골 원위부 과간 골절은 소아에서는 매우 드물게 발생되는 골절로 대부분 주관절의 굴곡상태로 주관절 후방부에 직접적인 충격에 의해 발생하는 것으로 보고되고 있다. 전위가 없거나 경미한 경우 도수적 정복술 혹은 도수적 정복술 후 경피적 핀고정술을 시행하며, 전위가 심한 골절이거나 도수적 정복술이 불가능한 경우 관혈적 정복술 후 핀고정술을 시행하는 것으로 알려져 있다. 저자들은 전위된 상완골 원위부 과간 골절 환아 2예에서 각각 도수적 정복술과 관혈적 정복술 후 K 강선 고정술을 시행하여 만족한 결과를 얻었기에 보고하는 바이다. Intercondylar fractures of the distal humerus are very rare in children. The pattern of the fracture would suggest that the mechanism of injury involves a fall directly on the flexed elbow. Most agree that the undisplaced fracture can be managed conservatively. With increasing displacement and comminution, the opinions tend to differ. We suggest that closed reduction with percutaneous K wire pinning and open reduction with percutaneous K wire pinning offer a satisfactory methods by which to treat displaced intercondylar fracture in children.

상완 신경총 마비는 쇄골 골절 후에 매우 드물게 발생하며, 대부분 많은 가골 형성을 동반한 쇄골의 중간1/3 부위 골절 불유합에서 발생한다. 골절의 치유 과정에서 과형성된 가골이 상완 신경총을 압박할 수 있으며, 감압술고 불유합에 대한 수술적 치료를 필요로 한다. 이에 저자들은 쇄골 골절 후 불유합과 과도한 가골 형성에 의해 발생된 지연성 상완 신경총 마비 환자를 치험 하였기에 보고하는 바이다. The brachial plexus palsies secondary to nonunion of the clavicle fracture are extremely rare. The nonunions are hypertrophic and usually in the middle third of the clavicle. Hypertrophic callus produced healing process will cause a compression of the neurovascular bundle. This lesion requires operative treatment for decompression of the brachial plexus and internal fixation of nonunion. We present a case of delayed brachial plexus palsy due to nonunion and excessive callus formation of a clavicular fracture.
