We as a civil investment enterprise have been constructing In-cheon International Airport Railway which is a transportation means to approach In-cheon International Airport. In this alignment, a section between the Seoul station and Ka-joa follows the existing Yong-san line at the center of Seoul city and traverses Seoul subway 2,5,6 lines. So we planned that the alignment would have the shallowest depth to lie under Kyung-eui line and above the airport railroad. The alignment is planned to construct an open-box structure only 3.6m apart from the subway line 5 tunnel structure and construct the open-box structure 0.7m apart from the subway line 2 box structure. In the line planning, we investigated both the security of the existing subway structures during and after construction and the stability and workability between newly structured tunnel structures with three dimensions numerical analysis methods. Also we raised the reliability of design verification which was achieved by specialty society"s review on the planned construction method.

This study' was performed to measure the changes of the mandibular movement and the masticatory muscular activities anterior temporal and masseter muscle of both side - reflected by intentional increase of anterior guidance angle. For this study, 5 volunteers (3 males and 2 females with average age of 24.0) were selected. Each volunteer had Angle's classification I and did not have any missing tooth except third molar and any extensive restorations. Metallic guide plate was made at volunteer's working model fabricated by improved dental stone and cemented to the palatal surface of maxillary central incisor using resin cement(Panavia 21�) and then adjusted not to give any occlusal interferences at intercuspal position. The activity of masticatory muscles and the changes of mandibular movement were recorded by EMG and Sirognathograph in Biopak analysing system(Bioresearch Inc., Milwaukee, Wisconsin, USA). Measurement was done at before experiment, irnmediatley after placement, 1 week after placement, immediately after removal, and 1 week after removal. The results were as follows: 1. Moderate phonetic disturbance and mild headache were occured to 3 volunteers for 2 days after setting and l volunteer had positive reaction to percussion and slight midline diastema. But all of these clinical signs were diappeared 1 week after removal and the other volunteer did not have any special clinical sign. 2. In the EMG of the mandibular rest position, the mean value of anterior tempotal muscle was increased immediately after placement(p<0.01) and then decreased 1 week after placement(p<0.05) and increased 1 week after removal(p<0.05) but not recovered as before experiment. The mean value of masseter muscle was decreased during the experiment period: 3. In the EMG during mandibular protrusive movement, all muscular activity was decreased during the experiment period. Reduced activity was not recovered I week after? removal(p<0.05). 4. During the habitual opening, anteroposterior movement of mandible was decreased immediately after place ment(p<0.05) and then increased 1 week after placement but not statistically significant(p>0.1). Vertical movement was not shown significant difference during the experiment period(p>0.1). Lateral movement was decreased immediately after placement(p<:0.05) and then increased 1 week after placement but not recovered as before experiment. The opening and closing velocity of mandible was shown minor changes but not statistically significant. 5. During the habitual opening, anteroposterior movement of mandible was decreased 1 week after placement(p<0.(6) and then increased immediately after removal and recovered 1 week after removal as before experiment. Vertical movement was not shown significant changes. Lateral displacement of mandible was increased continuously and recovered 1 week after removal. Opening velocity was temporarily increased immediately after removal but recovered and closing velocity was not shown significant changes. 6. During the right side chewing, anteroposterior movement of mandible was increased immediately after removal but recovered and vertical movement was not shown statistically significant results. Lateral displacement and velocity o mandible were not shown significant results. 7. During the left side chewing, the changes of mandibular movement pattern were not shown statistically significant results.

Facial asymmetry can be most distressing for the young child and parents. It can cause functional problems as a result of malocclusion. Classification of facial asymmetry has not been yet well-organized because of its varieties on etiologic factors, involved sites and clinical expressions. Even though, we don’t know its causes definitely. It is generally believed that problems with aberrant pattern of condylar growth are related to facial asymmetry. This is a case report on surgical correction of the patients who had severe facial asymmetry. One patient was diagnosed as condylar hyperplasia and the other was diagnosed as a condylar hypoplasia related to trauma. We performed a simultaneous two-jaw surgery, condylar shaving, inferior border ostectomy of affected mandible in the former case, and a simultaneous two-jaw surgery, reverse-L osteotomy and alloplastic implantation with Biocoral in the latter case. The postoperative results of the two cases were excellent functionally and esthetically.

Since the residential load is an AC load and the output of solar cell is a DC power, the photovoltaic system needs the DC/AC converter to utilize solar cell. In case of driving to interact with utility line, in order to operate at unity power factor, converter must provide the sinusoidal wave current and voltage with same phase of utility line. Since output of solar cell is greatly fluctuated by insolation, it is necessary that the operation of solar cell output in the range of the vicinity of maximum power point. In this paper, DC/AC converter is three phase PWM converter with smoothing reactor. And then, feedforward control used to obtain a superior characteristic for current control and digital PLL circuit used to detect the phase of utility line.

저자들은 brodifacoum성분의 지속형 효과를 갖은 항응고제인 쿠마린계 살서제를 정확한 용량을 추정할 수는 없지만 다회의 약물 복용 17일 후 뇌실질출혈이 발생한 증례를 문헌 고찰과 함께 보고하는 바이다. 지금껏 쿠마린계의 지속형 항응고성 살서제의 약물 중독이 알려져 있다. 이러한 약물은 vitamin K₁ 2,3-epoxide 환원효소를 억제하여 vitamin K₁과 연속적으로 vitamin K₁ 의존성 응고인자 Ⅱ, Ⅶ, Ⅸ, Ⅹ의 합성을 억제하고 이로써 출혈 경향을 증가시킨다. 이 증례를 토대로 향후 출혈성 환자 특히 선행 질환이 없는 젊은 뇌실질출혈 환자에서 원인을 감별진단 함에 있어 환자의 약물 중독 가능성과 치료에 대한세심한 주의가 필요할 것으로 생각한다. Spontaneous intracerebral hemorrhage is one-tenth of all strokes and represents relatively high frequency and morbidity. Hypertension is the most common cause of spontaneous intracerebral hemorrhage and other causes are vascular malformation, intracerebral amyloid angiopathy, hemorrhagic infarction, blood diseases and drug abuse. Some peoples have the intoxication of drug such as long-acting anticoagulant of rodenticides, family of cumarin, that inhibit vitamin K₁ 2,3-epoxide reductase, the synthesis of vitamin K₁ and subsequently vitamin K₁ dependent clotting factors Ⅱ, Ⅶ, Ⅸ, and Ⅹ. Finally these make prolonged PT, INR and aPTT, which are prone to trigger bleeding tendency. We report a rare case of intracerebral hemorrhage maybe caused by after frequent intended ingestion of long-acting anticoagulant rodenticide(brodifacoum) for suicide.

Crouzon's disease has three characteristics that are craniosynostosis, enophthalmos, and midfacial hypoplasia. Among these characteristics, craniosynostosis causes restriction of cranial and brain growth and variable morphologic deformities. An inadequate intracranial volume causes increased intracranial pressure(IICP) and functional impairment. Classic surgical decompression is frontal advancement with vault remodeling, but it may have drawbacks such as invasiveness, long operation time, difficulty of postoperative care, frequent complication and large amount of hemorrhage. We compared cranial distraction osteogenesis with classic surgical method in terms of their merits and drawbacks and reached to conclude that the cranial distraction osteogenesis is more effective than the classical surgical methods in Cronzon's disease. We treated a 12-month-old female with frog-like face, who had no IICP using cranial distraction osteogenesis, and gained a satisfactory result. In conclusion, the application of distraction osteogenesis in correcting bicoronal & sagittal craniosynostosis is very effective.

Titanium oxide was prepared by the hydrolysis of TiCl_4 and was coated on mica. The optical characteristics such as reflection and transmission of the latter was studied. The effects of concentrations of TiCl_4 on the rate of hydrolysis, particle size of hydrolysis product (Ti0_2), and crystal induction time, were found to be quite reverse to the general principle. Graphical analysises show that the crystal induction time was shorter as the concentra-tion of TiCl_4 decreased. By proper regulation of the condition of hydrolysis of TiCl_4 solution, mica pigments of colours ranging from silver-white to red was produced. Their maximum intensity of light reflection and maximum transmittance were from 300 to 800nm and from 400 to 700nm respectively.

Non-Hodgkin's 림프종의 약 40%는 결절외(extranodal) 림프종으로 대개 위장관에서 발생하며 이들 중 점막 연관 림프조직(mucosa-associated lymphoid tissue: MALT)에서 기원한 림프종은 MALT 림프종으로 분류된다. 위 외의 부위에서 원발성으로 발생하는 MALT 림프종은 매우 드물지만 실제 거의 모든 신체 장기에 발생하는 것으로 알려져 있는데, 가장 흔한 부위인 위 외에도 폐, 갑상선, 침샘, 눈물샘에 발생하고, 드물게 안구, 유방, 방광, 신장, 흉선 등에도 보고된 바 있다. MALT 림프종은 오랜 기간동안 원격 전이하지 않고 국소 병변으로 남아 있는 특징이 있어 치료 방향 또한 국소 병변의 치료에 집중되며, 예후도 림프절 기원의 림프종에 비해 양호한 것으로 알려져 있다. 본 저자 등은 자궁 내막에 원발성으로 발생한 MALT 림프종 1예를 경험하였기에 문헌 고찰과 함께 이를 보고하고자 한다. Mucosa associated lymphoid tissue (MALT) lymphoma can rarely develop primarily in extranodal sites other than stomach which is the most common site for it. Other rare primary sites are small intestine, colorectum, esophagus, lung, thyroid, salivary gland, lacrymal gland, breast and skin. MALT lymphoma represents a distinct clinicopathologic features: it is usually localized to their original site for a long time and shows much more favorable prognosis than lymphoma at other site, but some MALT lymphoma can arise simultaneously or successively in different organ or give rise to another MALT lymphoma of other organ and can be multifocally disseminated or recurred. We report a very rare case of high grade B-cell lymphoma of mucosa associated lymphoid tissue (MALT) of the uterine endometrium, which was confirmed by immunohistochemical assay.
