Apophyseopathy in human growing-up period is divided in three parts, early stage, advancing stage, and ending stage which are analyzed by X-ray test. The tuber of kantenabtrennung, schmorl and rear oxhorn dissociation are one of the these barrier process. We assume that the fracture of apophysis by overusing is the main cause of these barriers.

Crohn`s disease is a chronic inflammatory bowel disease that can involve the whole gastrointestinal tract. The orofacial manifestation of Crohn`s disease, which is rare, can develop irrespective of intestinal involvement. These orofacial lesions are often misdiagnosed as simple oral ulcers. Corticosteroids are the mainstay of therapy for orofacial Crohn`s disease. However, infliximab, the chimeric monoclonal antibody to tumor necrosis factor-α, is now considered as a primary treatment because of the disease`s relatively high rate of steroid resistance. We present a case of deep oral ulcer and periorbital swelling in a 65-year-old woman. She was diagnosed with intestinal Crohn`s disease 7 years ago, which was in remission after treatment with an immunosuppressive agent (azathioprine). The patient was given the diagnosed with orofacial Crohn`s disease and successfully treated with infliximab. (Korean J Gastroenterol 2012;59:437-440)

A number of methods have been introduced for support the orbital floor following a maxillectomy without orbital exenteration or severe facial trauma. These methods including skin graft and muscular sling provided the unsatisfactory results, like as diplopia, orbital ptosis, enophthalmos and severe facial deformity. Therefore the bone and soft tissue reconstructions using microvascular free flaps were performed recently by many surgeons, but long time operation, donor site morbidity, postoperative large scar, and ptosis of the flap were pointed out as disadvantages of free flap reconstruction. Vascularized calvarial bone flap, a modified method of free calvarial bone graft, was adequate for reconstruction of the orbital floor and the infraorbital rim as a horizontal buttress, especially in case of poor vascular bed and postradiated state. The authors introduced the vascularized calvarial bone flap for the orbital floor and the infraorbital rim reconstruction in 3 cases of maxillectomy, and could be obtained satisfactory results aesthetically and functionally.

This study was carried out to evaluate performance of sewage treatment facility in rural area. Average effluent concentration was 7.6㎎/1 BOD. 10.3㎎/1 COD, 4.7㎎/1 SS, 19.140㎎/1 TN, and 1,631㎎/1 TP, within discharge quality standard. The removal efficiency rate of BOD, COD and SS was good as 89.8%. 78.5% and 90.1%, respectively. But that of TN, TP was very low as 25.0% and 31.4% respectvely. Average sewage flow rate was investigated by about 1.1㎥/d per household, 398ℓ pcd. In rainfall period, the removal efficiency rate of BOD. TN and TP was very low as 15%, 22% and 28%, respectively because of inflow and infiltration into sewer. In flowing concentration of sewage was diluted as rain is inserted into sewer and submerged facility was not operated at normal condition. Therefore it is required that the sewer will have to repair and hydraulic design for facility will have to be check. So it is necessary to support systematical, administrative measures for responsible management.

In this paper, the effect of shot peening on the fatigue characteristics have been investigated. Two types of specimens were used to obtain the experimental results. One type of specimen was made by machining and heat-treating SCM415 steel. The other type of specimen was made by machining, heat-treating, and shot peening SCM415 steel. The hydraulic testing machine was used to do the fatigue test (R=0.1, 10Hz). The experimental results show that the fatigue life and strength of shot peened gear were largely improved compared with the unpeened gear.

This study was conducted in an attempt to investigate the interrelationship among breast milk, blood and urine lead levels of lactating mothers. The milk lead levels were measured with samples obtained from 89 mothers dwelling in Seoul city, Kyunggi-Do and Kangwon-Do area. The blood and urine lead levels were measured in mothers dwelling in Seoul city. Analytical method used for the study was atomic spectrometric method using atomic absorption spectrophotometer by Farrelly and Pybus method(1969). The results were as follows : 1. The lead levels were trace and could not measured in the 89 brest milk samples. 2. The average urine lead levels of 10 mothers was 3.99±0.44㎍/100㎖. 3. The average blood lead levels of 10 mothers was 21.28±3.51㎍/100㎖.

최근 복수전공, 자유전공, 심화전공, 그리고 학부제 등이 도입됨에 따라 특정전공교육이 다른 전공이 제공하는 강의서비스에 의존하는 정도가 증가하고 있는 실정이다. 따라서 전공별 또는 원가대상별 강의용역상호수수관계를 고려하지 않고는 정확한 원가계산이 불가능하다. 본 연구에서는 첫째 강의인건비를 집계하는 과정에서 사용할 강의용역상호수수관계를 파악하는 방법을 제시하였다. 둘째, 교육원가계산에 있어서 고려해야 할 중요한 요인인 교육원가대상을 정의하는 방법을 제시하였다. 본 연구에서는 전임교수의 인건비 중 급여성 연구비는 연구활동비로 분류하지 않고 강의인건비에 포함시키는 방법을 제시하였다. 그리고 전임교수 인건비를 강의용역상호수수관계를 파악하여 교육원가대상에 배분할 때 원가대상의 실제 강의인건비를 사용하지 않고 원가대상이 소속된 대학별로 강의시간당 평준화 인건비를 사용하였다. 그리고 특정대학에 소속된 원가대상의 강의수수 양태가 동일한 대학에 소속된 다른 원가대상과 확연하게 다르다고 생각되는 경우에는 대학별 평준화 인건비를 사용하지 않고 학과(부)별 평균인건비를 사용하는 것이 합리적이다. 시간강사인건비는 대학별로 시간당 평균인건비를 계산하지 않고 부산대학교 전체의 강의시간 당 평균인건비를 계산하여 사용한다. 본 연구에서는 교육원가대상을 학부(과)의 경우에는 기초과정, 전공과정, 일반대학원과정을 개별 원가대상으로 정의하였고 특수대학원은 전공별로 원가대상으로 분류하였다. 그리고 교육원가대상이 대학의 구조조정에 따라 달라지는 경우에는 교육원가계산을 수행하는 연도의 학제를 기준으로 교육원가대상을 정의하였다.
능동 클램프 ZVS 플라이백 컨버터의 역률개선에 관한 연구

본 논문에서는 single-stage, two-stage 두가지 역률보상(PFC)기법을 기존의 능동 클램프 플라이백 컨버터에 적용하여 역률 개선을 하였다. 삽입된 플라이백 컨버터의 능동클램프회로가 주스위치와 보조스위치의 영전압스위칭(ZVS)을 구현하며, 스위칭 손실을 줄임으로써 고효율을 얻을 수 있고, 높은 주파수에서의 스위칭이 가능하다. 하지만 일반적으로 사용되는 다이오드정류기, 평활용커패시터에 의한 낮은 역률의 문제점이 남아있다. 본 논문에서는 300W급 능동 클램프ZVS플라이백 컨버터를 설계하여 single-stage, two-stage방식을 적용, 입력역률개선을 시뮬레이션과 실험에 의해 입증하고자 한다. This paper analyzed PFC of active clamp ZVS flyback converter by adding two method PFC (Power Factor Correction) circuit - two-stage and single-stage. The addition of active clamp circuit also provide a mechanism for achieving ZVS of both the primary and auxiliary switches. ZVS also limits the turn off di/dt of the output rectifier, reducing rectifier switching loss and switching noise, due to diode reverse recovery. As a results, the proposed converters have characteristics of the reduced switching noise and high efficiency in comparison to conventional flyback converter. The simulation and experimental results show that the proposed converters improve the input PF of 300W ZVS flyback converter by adding single-stage, two-stage PFC circuit.
