The Orbital fracture which is often combined with midface fracture can cause decreased visual acuity, limitation of eyeball movement, diplopia, enophthalmos, etc. Traumatic orbital fracture causes change of orbital volume, results in diplopia and enophthalmos thus, accurate repositioning of displaced bone and reconstruction of orbital defect with autogenous materials(cranial, rib, iliac bone, cartilage and fascia lata) or alloplastic materials(gelatin film, polyglactin mesh, methylmethacrylate, Teflon, silicone, Supermid, hydroxyapatite and metal). The key point of reconstruction of orbit is accurate repositioning of displaced orbital floor, lateral, medial orbital wall and sufficient bonegraft in anatomical defect. As this cases, we obtained good results through transconjunctival and coronal approach who were required orbital reconstruction. Also, we accurately diagnosed orbital fracture with C.T., 3D model and good result for orbital reconstruction with sufficient parietal block bone graft during average 16.8 months follow-up.

Percutaneous automated lumbar discectomy as it is now practiced appears to be an extremely safe procedure. One hundred fourty eight patients with lumbar disc herniation were treated with automated percutaneous lumbar discectomy(A.PL.D.). The postoperative results in 118 patients were evaluated at more than 3 months after the operation. Total satisfactory result was 74% excellent 16%, good 58%, fair 22%, poor 4% by Macnab' s criteria. For further satisfactory result, more meticulous crteria is needed. The results indicated that several prognostic factors were considered : 1) less than 30 years of age, 2) more than 4ml of aspirated disc volumn, 3) L4-5 of disc level, 4) follow up X-ray change(59%), but no CT change and possible MRI change.

Performing genioplasty for greater stability of the changed chin position, incision, dissection, osteotomy design and fixation are important technical considerations. Basically, wire osteosynthesis method has been used in genioplasty, but plate/screw osteosynthesis has been introduced in rigid fixation. The purpose of this study is that comparison of stability between wire and plate/screw osteosynthesis in genioplasty. In this study, the genioplasty groups were divided into three groups ; advanced genioplasty group, reduction genioplasty group, advanced with reduction genioplasty group. In wire osteosynthesis groups, there were 15patients who had advanced genioplasty, 13patients who had reduction genioplasty, and 12patients who had advanced with reduction genioplasty. In plate/screw osteosynthesis groups, there were 15patients who had advanced genioplasty, 13patients who had reduction genioplasty, and 13patients who had advnaced with reduction genioplasty. Lateral cephalograms ; pre- and postoperatively, postoperatively 1months, and at the latest follow-up(>6months); were analyzed by linear measurement to evaluate changes in position(hard tissue B, Pogonion point) and compare relapse between both groups.

Subcutaneous air emphysema is a relatively uncommon phenomenon. It has been reported in both the medical and dental literature following such various procedures as rectal biopsy, nasogastric intubation, radical neck dissection, tonsillectomy, adenoidectomy, root canal treatment, dental restoration and extraction of maxillary and mandibular teeth. The most common cause involves extraction of mandibular third molar. Subcutaneous emphysema of the head, neck and thorax is a swelling caused by introduction of air into the space of the connective tissue. The clinical signs are local swelling, tenting of the skin, and crepitation on palpation. In extreme casesk, air has been reported to pass through the masticatory space into the parapharyngeal and retropharyngeal space, and penetrate into the mediastinum. If the inflowing air contains bacteria, serious infection may ensue. The first case of subcutaneous emphysema associated with a dental procedure was first reported in 1900. This emphysema is a often limited only to the spaces of head and neck, but also can involve deeper structure. This case is diffuse subcutaneous emphysema following maxillary third molar extraction with a high-speed drill.

This research studied the characteristics and applicability of electrocoagulation using aluminium electrode for the color and COD removal in textile wastewater. Electrocoagulation reactor used two different electrode, Fe and Al, since in the general chemical wastewater treatment, aluminium and ferrous salts were used as coagulants. Aluminium electrode showed higher removal efficiency of color and COD than ferrous electrode did. The COD and color removal efficiency improved at the 0.192A/dm^2 current density. Thus, the electrocoagulation process with bipolar aluminium electrode showed better efficiency in the decolorization and COD removal rate of textile wastewater effluent than custom coagulants did.

New water-soluble conjugated aromatic polyimine containing sulfonate groups have been synthesized by means of polycondensation reaction between corresponding diamines and dialdehyde at room temperature. The polymers synthesized were soluble in water and N,N-dimethylformamide, giving colored solution. Self-assembled multilayer films consisting of the each polyimine as a polyanion and poly(diallydimethylammonium chloride) as a polycation were fabricated successfully by alternate deposition in corresponding aqueous solutions.

The purpose of this study is to propose an efficient design-VE job plan and applicable methods in each phase of design process. This is for more effective and practical use of VE in design phase. This study focuses on differences of the VE target selection phase and function analysis phase in each phase of design process. In the phase of preliminary design, conceptual sketch, size, use, or major spaces of project are selected for VE target and function assessment step is skipped because present cost and function cost cannot be produced easily in early in early phase of design. At the end of preliminary design phase, function review phase is added which consists of function satisfactory indices review step and unsatisfactory function removal step.

이 연구는 초등학교 과학 성적 우수아를 대상으로 과학계발활동 프로그램의 구성 및 적용이 과학탐구능력에 미치는 효과를 분석하였다. 분석결과, 과학계발활동 프로그램을 적용한 학생들은 적용하지 않은 학생들에 비하여 관찰, 측정, 자료해석, 가설 설정, 변인통제의 과학탐구요소가 더 신장된 것으로 나타났다. 따라서 과학계발활동의 운영은 과학탐구능력의 신장에 효과를 기대할 수 있으므로 교육현장에서 과학교육을 보다 다양하고 수준별로 운영할 수 있는 프로그램의 개발 및 적용 방안을 모색할 필요가 있다. This study organized a Science Improvement Activity Program designed for the excellent students in science in 5th and 6th grades. After application the effect of the program on science process skills was analyzed. The Science Improvement Activity Program was applied to the experimental group as a club activity after school during the semester. The results of this study were as follows: First, the students participated in the Science Improvement Activity showed an increase in the science process skills compared with those who didn't. Second, it was found that the students to whom the Science Improvement Activity Program was applied have improved in enhancing their science process elements of observation, measurement, data analysis, forming hypotheses, and controlling variables. It is expected that the development of activity programs and their active application should be done in order for schools to provide science education according to each student's capacity from various angles.
