한상철,정경희,Han, Sang Cheol,Chung, Kyung Hee 한국강구조학회 1999 韓國鋼構造學會 論文集 Vol.11 No.2
ALFD방법은 연속합성판형교의 과재하중과 최대하중에 대한 강도검토에 있어서 실제적인 거동을 나타낼 수 있는 탄소성해석법이다. 주어진 하중으로 인한 최대 정, 부모멘트단면에서의 항복은 활하중이 통과한 후에 잔류하는 소성회전을 일으킨다. 또한 제조시의 잔류응력으로 인하여 이론적인 항복모멘트 이하에서도 소성변형을 일으킨다. 이러한 국부항복은 다음에 작용되는 과재하중하에서 탄성화되어 정의 자생모멘트를 유발한다. 본 연구에서는 지점과 최대 정모멘트 단면에서의 단위소성회전각으로 인한 자생모멘트를 공액보법과 3연모멘트법에 의하여 구하였고, 9개의 설계경간을 지점단면을 감소시켜가면서 본 연구에서 개발한 전산프로그램에 의하여 연속관계와 모멘트-비탄성회전각 실험곡선과 일치하는 자생모멘트를 구하였다. 또한 한국도로교시방서에 준하여 비조밀단면을 갖는 3경간 연속합성판형교의 평가를 수행하였다. Elastic-plastic methods have been used for the better prediction of the actual behavior of continuous-composite plate girder bridges in the overload and maximum load analysis. The structural evaluation using ALFD(Alternate Load Factor Design) uses the elastic-plastic analysis. The plastic rotations that remain after the load is removed can be occurred by the yielding locations of the maximum moment section. This situation can occur due to the residual stresses even if the moment is below the theoretical yield moment. The local yielding causes positive automoments that assure elastic behavior under subsequent overloads. In this study, the automoments at the piers occurred due to the unit plastic rotations and other locations were calculated by the conjugate-beam method and three-moment equation, using the nine design span with progressively smaller pier sections. The automoments were determined by the developed computer programs in this study in which the moments and plastic rotations from the continuity and moment-inelastic rotation relationships must be equal. And also the ratings of 3-span continuous composite plate girder bridges with non-compact section were carried out according to the Korean Highway Bridge Specification.
공간분활 및 영역열량측정에 의한 공평 자동난방운영시스템 구현
한상철,류광렬,Han, Sang Cheol,Ryu, Kwang Ryol 한국정보통신학회 2019 한국정보통신학회논문지 Vol.23 No.8
본 논문은 주거공간영역 별로 사용 난방열량을 측정하고 사용량을 자동으로 측정 분석하여 계량 운영 할 수 있는 공평관리 자동난방운영시스템의 구현이다. 난방공간은 4영역으로 분할하여 하나의 계량기로 유량과 열량이 계측된다. 이 시스템은 열량검출, 온도조절기, 밸브제어기, PC컨버터와 모니터링으로 구성된다. 난방 공간영역은 실내온도에 따라 열량 계산에 필요한 환수 온도가 측정되고 영역별 열량이 산출된다. 실험결과, 측정기기로 계측한 값과 비교하여 측정열량 값의 오차 범위는 1% 내이다. 기존의 유량계를 이용한 난방 분할 방식과 비교하면 난방 에너지 사용 비용이 약 7% 저감된다. 이 공평시스템은 향후에는 BEMS와 공동으로 연계하는 연구가 필요하다. This paper describes the system implementation of the heating operation based on spatial distributing and zonal calorie measuring and analyzing of houses to calculate the fair amount of the heating meterage automatically. The heating space is distributed into 4 zones, which the flow rate and calories are checked by one meter respectively. The system is composed of a heating sources, adjuster of thermostat, valve controller, PC converter and total monitering. The returning temperature in the spatial zones is measured for the heating calorie to calculate the zonal calories according to the rooms temperature. The proposed system results in error by 1% or less in comparing with the dedicated experimental equipment, and reduces energy cost by 7% from conventional system. The fair checking system will be enhanced with building energy management system in the future.

YBCO bulks with fine $Y_2BaCuO_5$(Y211) particles have been prepared by the top-seed modified powder melting process method, Solid-Liquid Melt Growth(SLMG), with $Y_2O_3$, $BaCuO_2$ and CuO mixing precursor. By using $Y_2O_3$ instead of $Y_2BaCuO_5$ as precursor, the processing became to be simpler and cheaper than the current powder melting process. The microstructures, trapped field and critical current density of the various conditioned YBCO bulks have been analyzed and the effect of Pt additive was studied. The different trapped magnetic field values of the several samples have been explained in the viewpoint of their microstructures. The fabrication of large-sized YBCO single domain has been conducted.
생산적 여성 근로자의 생활체육 참여가 직무스트레스와 탈진 및 신체적 증상에 미치는 영향

In recent years, because of increased mechanization, civilization, automation & modernization, the participation for regular exercise has decreased, because of busy life style, do not make time available to exercise. Because of this we are suffering diseases & fatigue associated with inactivity. Furthermore, because of conglomeration, professionalization & complication of enterprises, the mechanized humanity has increased, because of this we are lost our emotional & psychological aspects. By understanding of these aspects, this study have focused on proposing the effective prevent measure of job stress, burnout & physical symptoms, by verifying the effects of the participation of regular sports of factory workers on the job stress, burn out, & physical symptoms, and verifying the relations of the job stress, bum out, & physical symptoms. For this study, 246 single female factory workers in the A company in Buchon were selected as the subjects. The questionnaire for verifying job stress of factory workers used the questionnaire of Ban, Jongjin(2000). and for verifying burnout & physical symptoms used the questionnaire of Kim, jongin(1997). For the data analysis, MANOVA and ANOVA and multiple regression analysis are used. The results of the study are as follows: First, The difference of job stress between non sport participation subjects and sport participation subjects are significant. Second, The difference of bum out among the sport participation subjects are not significant. Third, The difference of physical symptom among the sport participation subjects are not significant. Fourth, The factors of burnout are related to the factors of job stress of subjects. In particular, the emotional bumout, lack of personal achievement, distorted personality are related to the conflict of job position. The factors of physical symptoms are related to the job stress of subjects. In particular, the symptoms of cardiovascular, digestion, neuromuscular are related to the conflict of job position, the symptoms of the sleeping trouble are related to the overload in particular.
5.8 GHz 대역 근거리무선통신용 Radio Frequency 모듈 설계 및 구현
한상철 ( Sang-cheol Han ),임인성 ( In-sung Yim ),오승엽 ( Seung-hyeub Oh ) 한국고등직업교육학회 2002 한국고등직업교육학회논문집 Vol.3 No.4
This paper proposes the specifications of the RF module of 5.8 GHz dedicated short range communications, which are available to both time division duplex and a variable channel method. The design and implementation of a transceiver of radio frequency module are accomplished on the basis of the proposed specifications. The implemented transceiver shows 45 dB of the interference suppression and -76 dBm of receiving sensitivity when On/Off keying modulation is adopted. Therefore, the implemented radio frequency module is acceptable to the system with 2 Mbps transmission rate. In designing the radio frequency module, it is considered that the harmonics from each device do not interfere each channel. A Wilkinson power divider is used in the part of antenna/duplexer. Because the frequency band of the implemented module is variable, it is applicable to various radio frequency modules.
