韓秉基,鄭剛,金二圭 弘益大學校 1987 弘大論叢 Vol.19 No.2

In this study, a Optimum design equation of general corrugated plates(Vee type plate and Trough type plate) according to the inclined-angle(θ) of plates and aspect ratio(m) is derived to attain the Optimum values of those plates under axial compression. The merit function is to minimize the weight of plates, and the failure constraints are assumed that the applied stress not excesses Euler buckling stress,. local buckling stress, and yielding stress. As a consequence, the conclusions are followed as; 1. The Optimum angles θ of Vee type plate and Trough type plate are 45°, 30° (for m=1), respectively. 2. For the same weight of Vee and Trough type plate, the Trough type plate is more optimum than Vee type plate, then the angle(θ) and aspect ratio(m) of its. are θ=40°, m=0.2, respectively.

The purpose of this study was investigate implications of physical education curriculum's development from inspecting the reality and criteria of physical education curriculum in the secondary school. The conclusions of this study were as follows: First, physical education teacher executed physical education curriculum comparatively without regard to the national physical education curriculum. Second, factors considered in the development of the national physical education curriculum was the need of physical education teacher, the reality of facilities, and the need of students. Especially, the need of physical education teacher was mostly considered. Therefore, the actual place and reality of physical education was concidered in the development of the national physical education curriculum.

백색부후균 전처리에 의한 목재 칩의 Biopulping

강규영,김형진,양봉숙,조병묵,오정수 동국대학교 생명자원과학대학 연습림 2000 연습림논문집 Vol.- No.6

Pulping process is to mainly obtain lignocellulosic fibers for papermaking from wood resources. Three types of pulping method have been basically employed, such as chemical pulping, mechanical pulping, and their combination methods. Biopulping technique has been mainly applied in mechanical pulping by pretreatment of white-rot fungi into the ultrastructure of wood cell wall. The main purpose of biopulping is to improve the pulp qualities, paper properties, and to reduce the energy costs and environmental impact, compared to traditional pulping systems. Nowadays, biopulping is frequently tried in chemical pulping operation for environmental concept, fiber modification, improvement of physical properties of paper and economic savings. The pretreatment of white-rot fungi prior to chemical pulping could affect the swelling and softening of wood cell walls by the behaviors of modification and depolymerization of ligin compounds. This study was carried out to investigate the effectiveness of biological treatment to wood chips by white-rot fungus and its structural change of lignocellulosic fiber via kraft pulping. A rotary bioreactor was applied for pretreatment of biological action. The treatment of white-rot fungus was shown in weight loss of chips. After bio-kraft pulping, kappa number and total yield of pulps were measured, and reduced. Freeness(CSF) values were also decreased. Whereas brightness values were increased, compared to untreated control. The physical strength of handsheets was shown a slight increase in tensile, tear, burst, and folding endurance, with bio-treatments.

서병욱,박영호,이남규,전윤수,김민의,김영호,송윤섭,구자현 순천향의학연구소 1999 Journal of Soonchunhyang Medical Science Vol.5 No.1

We intended to determine the usefulness of window operation for adult hydrocele repair. We reviewed medical records of 132 patients from January 1995 to June 1998 with primary hydrocele and evaluated complications and recurrence rates of eversion and/or excision, plication, and internal drainage technique. Recurrence rate was highest in internal drainage technique as 85.2%, and those of eversion and/or excision and plication technique were 1.3% and 4%, respectively. Complication rate was highest in eversion and/or excision technique, and lowest in internal drainage technique. Although complication rate was lowest in window operation, this operation could not be successful due to high recurrence, and we suggest that this operation should be abandoned for hydrocele repair.
