Objective : The purpose of this study was 1) to analyze clinically-executed cervical lateral mass screw fixation by the Kim's technique as suggested in the previous morphometric and cadaveric study and 2) to examine various complications and bicortical purchase that are important for b-one fusion. Methods : A retrospective study was done on the charts, operative records, radiographs, and clinical follow up of thirty-nine patients. One hundred and seventy-eight lateral mass screws were analyzed. The spinal nerve injury, violation of the facet joint, vertebral artery injury, and the bicortical purchases were examined at each lateral mass. Results : All thirty-nine patients received instrumentations with poly axial screws and rod systems, in which one hundred and seventy-eight screws in total. No vertebral artery injury or nerve root injury were observed. Sixteen facet joint violations were observed (9.0%). Bicortical purchases were achieved on one hundred and fifty-six (87.6%). Bone fusion was achieved in all patients. Conclusion : The advantages of the Kim's technique are that it is performed by using given anatomical structures and that the complication rate is as low as those of other known techniques. The Kim's technique can be performed easily and safely without fluoroscopic assistance for the treatment of many cervical diseases.

본 연구는 폐비닐 펠렛을 도로포장재료로 재활용하여 자원절약 및 아스팔트 혼합물의 품질향상을 위한 연구이다. 이를 위하여 폐비닐의 첨가량별 배합설계를 수행하여 적정 폐비닐 첨가량과 최적 아스팔트 함량으로 편마암과 화강암 2가지 골재와 폐비닐인 RHDPE의 함량을 4가지로 혼합물을 제작하여 8종류의 재질 혼합물과 2종류의 무개질 혼합물을 제작하였다. 그리고 이 공시체에 대하여 마샬안정도, 간접인장강도 및 Kim test와 반복주행시험 등 실내시험을 통하여 혼합물의 특성을 분석하였다. 폐비닐 첨가량은 RHDPE가 8%일 때 안정도와 간접인장강도 모두 가장 우수한 것으로 나타났고 취성도 나타나지 않았다. RHDPE를 첨가한 혼합물에 대하여 Kim test를 수행한 결과 DR과 DS 모두 높은 상관성을 보였다. 그리고 반복주행시험에서는 RHDPE를 첨가한 혼합물이 일반 혼합물보다 우수하였다. 향후 많은 실험을 통해 RHDPE의 우수성을 입증한다면 소성변형 저항성에 우수한 재료로 이용될 수 있을 것이다. This study is a fundamental research for recycled high-density polyethylene (RHDPE) in asphalt mixture for improving roadway pavement. Marshall mix design was conducted and optimum asphalt content(OAC) was determined for dense-graded surface course mixture by RHDPE content. Marshall stability test, indirect tensile strength (ITS) test, wheel tracking trest and Kim-test were carried out to measure the characteristics of RHDPE-added asphalt concretes. From the results of this study, RHDPE in asphalt mixture if possible. It could be considered that adding too much RHDPE in asphalt mixture is not proper. The optimum content of RHDPE was appeared to be 8%. In Kim-test, statistical analysis was performed for each loading head and aggregate to find out correlation between S_(D) values and each rut parameter. The analysis result showed that S_(D) had very high coefficient of determination with rut parameters on the average.

This study was carried out to test the body fat breakdown during topical seaweed extract treatment and in combination with the aerobic exercise. Of 20 female obesity subjects, ten treated a cream types of seaweed extract(control group) and ten treated a placebo cream(placebo group). Topical treatment of each sample was designed for 4 weeks, and treated with 2 times a day about 10ml on the abdomen and the thigh, respectively. All subjects were participated aerobic dance half hour a day and four times a week. After 4 weeks of topical treatment and exercise, they were measured body fat, skinfold thickness, body circumference. Then venous blood samples were taken and analyzed blood cells, serum enzymes, and serum lipids. There were reduction of body weight, % of body fat, antebrachium, brachium, chest, waist, thigh circumference and abdomen thickness between pre and post treatment in both group. Especially, body weight and % of body fat significantly reduced in the subjects treating the seaweed extract than those treating the placebo. There were significant decrement in total cholesterol and LDL whereas increment in HDL and TBIL in the control group, but no significant difference in the placebo group. In conclusion, there were 7.6% of body fat reduction during 4 weeks of aerobic exercise and 21% of body fat reducement in combination of topical seaweed treatment and exercise, respectively. These results suggest that the topical treatment of seaweed extract should be very effective for fat breakdown. Especially, the body fat breakdown maximized in the combination with the topical seaweed extracts treatment and the aerobic exercise.

배경: 주물공장 근로자에서 발생한 석면폐증의 작업 관련성을 평가하고 그 증례를 보고하고자 한다. 증례: 30년간 주물공장에서 근무한 환자로 인후통, 기침, 노란 가래가 있어 검사한 결과 결핵이 의심되어 치료 하였으며, 치료 중 석면폐증으로 진단되었다. 작업 관련성 평가를 위해 실시한 폐 조직의 조직학적 검사에서 1 cm^(2)당 3개의 석면소체가 발견되었고, 투과전자현미경으로 분석한 석면 함유량은 23.26x10^(6) fibers/g이었다. 결론: 작업환경조사, 폐 조직의 석면 분석 등을 통해 작업 관련성이 높다고 판단하였다. Background: Foundry workers are known to be exposed to silica and have an increased risk of Silicosis. There are also reports that state these foundry workers were associated with asbestos-related change in the X-ray results of the lungs. This report discusses a case of localized asbestosis developed in a foundry worker who worked in 12 Korean foundries. Case report: A 49-year-o1d man who worked at molding and melting for 30 years, Presented with sore throat, cough and yellow sputum for 1 month. From physical and clinical examination, Pulmonary tuberculosis was highly suspicious; therefore, he was medicated for 6 months. After tuberculosis medication, the radiological finding was reactivation of tuberculosis, and an asbestos body was detected at a trans-bronchial lung biopsy. During an operation, operators found multiple palpable masses and bullae 10calized in the right upper lobe (RUL) and performed right upper lobectomy and right middle lobe wedge resection. Using hematoxylin-eosin stain and iron stain, we could detect asbestos bodies by light microscopy. We analyzed the asbestos fiber burden in dry lung tissue by transmission electron microscopy with energy dispersive X-ray spectrometer (TEM-EDX). The fiber type was chrysotile and the fiber burden was 23.26 x 10^(6) fiber/g dry lung. Discussion: This case study of a foundry worker with localized asbestosis is uncommon in Korea. We found an occupational relationship between the foundry worker and localized asbestosis through various investigative techniques such as measurements taken at his working environment, clinical, radiological and pathological examination of the foundry worker and mineralogical examination of the asbestos fiber.

Purpose : Intraoperative suprachoroidal hemorrhage is one of the most serious complications. We report a case of suprachoroidal hemorrhage during phacoemulsification surgery, was managed properly. Methods : Suprachoroidal hemorrhage occurred during phacoemulsificaiton in other hospital. The patient was referred to our department immediately after closing the surgical wound. On initial examination, iris and vitreous were prolapsed through surgical wound. Ciliary body was closely place to anterior chamber, and retina was not visible. Results : Prolapased ocular tissue were reduced by emergency operation. We controlled the patient’s intraocular pressure and inflammation. Ultrasonography was repeatedly performed to check the degree of liquefaction of suprachoroidal hemorrhage. After 9 days of suprachoroidal hemorrhage onset, vitrectomy and drainage through sclera was performed. Postoperative state was stable with successful removal of suprachoroidal hemorrhage. After 2 weeks of secondary operation, retinal detachment has occurred on nasal retinal area, so we performed scleral buckling and endolaser photocoagulation. After 6 months, retina was attached well and intraocular pressure was in normal range. Conclusion : In suprachoroidal hemorrhage, drainage of suprachoroidal hemorrhage after liquefaction of thrombi is effective. After successful drainage, postoperative complications may accompany such as retinal detachment or elevation of intraocular pressure. 목적 : 술중 발생하는 맥락막상 출혈은 매우 심각한 합병증이다. 저자는 수정체 유화술 중에 발생한 맥락막상 출혈을 적절히 대처한 증례를 보고하는 바이다. 대상과 방법 : 수정체 유화술 중 발생한 맥락막상강 출혈환자가 수술창을 봉합 후 즉시 본원으로 전원되었다. 초진시 홍채와 유리체가 수술창을 통해 탈출되어 있었으며, 전방을 통해 모양체가 확인되었으나, 망막은 보이지 않았다. 탈출된 안구내 조직을 응급수술을 통해 복원 후 환자의 안압과 염증을 조절하였다. 초음파를 반복적으로 실시하여 맥락막상 출혈의 액화 정도를 확인하였으며, 출혈 9일 후 유리체 절제술과 공막을 통한 배액술을 시행하였다. 결과 : 맥락막상 출혈이 성공적으로 제거되었으며 술 후 상태는 안정적이었다. 수술 2주 후 비측 망막 박리가 발생하여 공막돌륭술과 안구내 삽관 레이저술을 시행하였다. 6개월 후 망막은 잘 붙어있었으며, 안압은 정상 범위를 유지하였다. 결론 : 맥락막상 출혈의 경우 출혈의 배액 시기를 결정하는 것이 어렵지만, 규칙적인 초음파를 통해 배액술의 시기를 결정할 수 있다. 또한 맥락막상강 출혈의 성공적인 배액 이후에도 망막박리 및 안압상승과 같은 합병증의 동반에 대해 유념해야한다.

Most of pile foundations which are carried out in the construction sites are used to transfer vertical load such as self weight to lower ground. But the piles which are used at abutment, open type wharf and slope are loaded not only vertical load but also lateral load such as earth pressure or wind pressure. Usually pile foundations are carried out in the form of group pile foundations. So in this paper, authors are going to deal with the behavior of laterally loaded group piles. With model piles, authors did some experiments by changing the relative density and the pile-space of pile-embedded-ground. According to the result of the experiments, authors have got characteristics of loadshare at each row in group piles. The results are as follows : 1. The Lateral load capacity for the initial horizontal displacement increases linearly and as the displacement is increasing, the behavior becomes parabolic. 2. The front row of piles is the highest in lateral load capacity, and the middle row of piles follow the front row. The tail row of piles is increasing, the loadshare-ratio of each row is accessing to the average loadshare-ratio. 3. As the space between piles is increasing, the loadshare-ratio of each row is accessing to the average loadshare-ratio. 4. In proportion to the increase of relative density, the lateral load of each row increases but the loadshare-ratio is not changed, despite the change of the relative density.

Discrete subaortic stenosis is a rare cardiac disorder especially in Orientals which occupies eight to ten percent of aortic stenosis, It occurs mainly before age of eighteen and accompanies with aortic valve abnormalities such as aortic stenosis, supravalvrlar stenosis, bicuspid valve and muscular hypertrophic subaortic stenosis, and other cardiac abnormalities such as ventricular septal defect, pulmonary stenosis and coarctation of aorta. There is no report of discrete subaortic stenosis accompanied with mitral valve prolapse. The major complications of discrete subaortic stenosis are aortic insufficiency, and subacute bacterial endocarditis. We report a case of asymptomatic nineteen-year-old male of discrete subaotic stenosis with bicuspid aortic valve and mitral valve prolapse, which is comfirmed by two-dimensional and Doppler echocardiography including transesophaigeal echocardiography.
