우리 나라 勞動運動史 小考

李聖惠,徐東範 목원대학교 사회과학연구소 2000 社會科學硏究 Vol.- No.4

우리 나라의 노동운동사는 그 역사가 일천하고 구미제국보다 약 1세기정도 늦게 출발하였다. 그러나 변천은 다양하므로 이를 정리하여 앞으로 우리 노사관계 정립에 보탬이 되고자 하였다. 조선중기의 "고공", "임용사공"에서 강화조약 이후의 "덕대제도"나 "노계"등의 전근대적 노동관계와 을사보호조약 후의 광산, 부두 노동자의 증가로 노동조합이 설립되기 시작하여 일제의 탄압 속에서도 굳건히 지켜오며, 때론 노동운동으로 흑은 민족해방운동으로 발전하였다. 해방 후 사상적 대립으로 좌 · 우간 갈등이 있었으나 6.25 동란으로 갈등은 종식되고, 후인 1953년의 노동법 개정으로 산별 노동조합이 활발하게 발전하였다. 5.16군사정권에 의한 산별노조가 1980년 노동법 개정으로 기업별 노조로 환원되었다가 6.29선언으로 노동자의 욕구가 폭발적으로 분출됨에 따라 1987, 1997년 노동법 개정으로 현재에 이르고 있다. 특히 IMF경제위기 후 노사의 국민 경제적 영향을 크게 인식하고 노사정 협의의 중요성이 크게 대두되고 있는 실정이다.

We developed science gifted education program related to the phenomena of floating and sinking phenomena, and analyzed the effects of this study. The concept of buoyancy force was represented as phenomena in the elementary school level science, and the concept of density was represented as formula calculation in middle school level science to explain floating and sinking materials. But the two concepts were not connected with each other in the textbooks. The subjects were 20 students of a science gifted class at a middle school located in Province. We surveyed their logic of proportion, the level of cognition, and the level of achievement before the instruction. And the conception test related to the floating and sinking phenomena was enforced before and after the instruction for identification of conception change. The problem solving ability test in a new situation and the students’ thought test related to the particle model carried out after the instruction, also. The education program was developed as a learning cycle and a discussion learning for understanding the relation between the buoyancy force and a volume, the density and a buoyancy force by students’ inquiry activity. As results, most of the students promoted understanding of the floating and sinking phenomena and changed the thoughts of particle model as polished viewpoint. 이 연구에서는 뜨고 가라앉는 현상과 관련된 영재교육프로그램을 개발하고, 프로그램의 효과를 알아보았다. 초등학교 과학에서는 현상 수준으로 부력의 개념을, 중학교에서는 공식 계산의 수준으로 밀도의 개념을 제시하여 물체의 뜨고 가라앉음을 설명하였으나, 이 두 개념을 연결 짓는 내용은 교과서에 제시하지 않았다. 연구 대상은 경기도 한 중학교의 영재학급 학생 20명이었으며, 수업 전에 이들의 비례논리, 인지수준, 학업성취수준을 알아보았다. 그리고 수업 전에 뜨고 가라앉는 현상에 관련된 개념 검사지를 투입하고 개념 변화를 알아보았다. 또한 새로운 상황에서의 문제 해결력을 알아보는 검사지와 입자모형에 대한 인식을 알아보는 검사지를 사후에 투입하였다. 개발한 영재교육 프로그램은 순환학습과 토론학습 형태로 학생들의 탐구활동을 통해 부력과 부피의 관계, 밀도와 부력의 관계 등을 이해할 수 있도록 구성하였다. 연구 결과,대부분의 경우 학생들의 배경 변인과 상관없이 뜨고 가라앉는 현상에 대한 이해도가 높아졌으며, 입자 모형에 대한 인식도 세련된 관점으로 변화하였다.

The relationship between precipitation in the Korea and vapor flux over the northern hemisphere is investigated by analyzing the characteristics of atmospheric circulation over the northern hemisphere and vapor flux transport, which is induced by wind vector and specific humidity at 850 hPa, for dry and wet summers in Korea. The data used in this study are monthly precipitation data at 7 stations of the Korea during the period of 1940 to 1997 and NECP/NCAR reanalysis data. The analysis of atmospheric circulation over the northern hemisphere associated with the interannual variation of Korean summer precipitation shows that the atmospheric circulation in dry summer is different from that in wet summer. The wet summer in Korea is characterized by the convergence of the monsoonal flow originated from the Indian Ocean with the southwesterlies along the northwestern periphery of subtropical Pacific high at 850 hPa. In contrast, the dry summer in Korea is characterized by the weaken southwesterlies inflow from the Bay of Bengal toward the East Asia via the Indo-China peninsula and the weaken southwesterlies inflow associated with the northward shift of subtropical western Pacific high. In addition, it is found from the analysis of 200 hPa and 850 hPa wind vectors that the interannual variation of Korean summer precipitation is largely linked with the location of axis of upper-level jet stream. The axis of upper-level jet stream is shifted more southward in wet summer that in dry summer. It is also found that the wet summer is related to the blocking occurrence over the Manchurian region. Thus, it can be suggested that the variations of the warm and humid air over the southeast part of Tibet and the location and intensity of subtropical western Pacific high play a significant role in the interannual variation of the precipitation in Korea.

In the world large amount of used printed circuit boards (PCBs) and spent autocatalysts which contain precious metals have been emitted. However, processes which can recover the precious metals simultaneously from them have not been developed yet. In this study a new process for recovering the precious metals contained in the used PCBs and spent autocatalyst by a pyrometallurgical process simultaneously was developed. The distinguish of that is to use copper, tin, and iron contained in the used PCBs as collector metals of the precious metals contained in the used PCBs and spent autocatalysts. Advantages of the process suggested are simply and economic compared with the previous processes which could recover the precious metals from the used PCBs and spent autocatalysts, respectively. Using the suggested process the precious metals such as Au, Pd, and Pt contained in the used PCBs and spent autocatalyst could be recovered up to 95 % in Cu alloy phase.
