The present study was performed to explore the antioxidant effect of selenium on damaged brain induced by organic mercury. Male ICR mice were given consecutively 7 injections for 7 days of : (I) sodium selenite 1 mg/kg s.c. alone, (2) methylmercuric chloride 10mg/kg s.c. alone, (3) methylmercuric chloride simultaneously in combination with sodium selenite, and (4) saline alone as control respectively. Based on the above protocol, we monitored various oxyradical scavenging system as well as the finding of electron microscopy. The results from brain tissues were as follows` 1. Selenium inhibited the rate of generation of superoxide radical.

There are difficulties to define the criteria that assort the leisure activities of old people as they are depended on the personality, educational background, economic level and habit of an individual. For example, the aged who are not healthy could be restricted to participate in community service or physical activities. Also elders who have lower levels of education hardly decide to enjoy reading or social activities. Leisure activity programs which support fruitful leisure activities for old people, as Korea goes into an aging society, are important because the improvement of educational back ground. economic level and health care give an extended average life expectancy. This study will suggest ways of leisure activities for old people with the understanding of their leisure pattern.

이 연구는 예비공학교육을 통한 미국의 국가 경쟁력 제고를 위하여 만들어진 프로그램의 내용을 살펴보는데 있다. 미국의 PLTW(Project Lead The Way)는 대학의 공학을 준비하기 위한 예비 공학 프로그램으로서 정규 교육 과정으로서가 아니라 공학을 위한 지식과 직업과 관련된 기본적인 경험을 제공하는 프로그램이다. 주요 내용은 미국의 과제중심 진로교육(PLTW)을 소개하고 초ㆍ중ㆍ고등학교 프로그램을 조사함으로써 우리나라 교육과정에 도입, 적용하는 방안을 모색하는데 있다. 이 연구에서 조사된 내용을 종합하여 다음과 같은 결과를 얻었다. 첫째, PLTW는 교육 시스템으로부터 졸업한 공학자와 공학 기술자의 양과 질을 늘이기 위한 공립 초ㆍ중ㆍ고등학교, 단과 대학 및 종합 대학의 고등 교육 기관과 민간 부문 사이의 협력을 맺은 프로그램이다. 둘째, PLTW는 예비공학 프로그램으로 6-12학년(초등학교 6학년~고등학교 3학년) 학생을 위해 공학에 기초 훈련을 제공한다. 이 프로그램은 공학과 공학 기술을 위해 2-4년제 대학이나 공업학교(technical school)에 입학하기 위한 필요한 것으로 학생들에게 제공하는 프로그램이다. 셋째, PLTW는 공학과 공학 기술 프로그램을 추구하여 2-4년제 공과 대학의 학위를 필요로 하는 학생 수를 증가시키고, 성(gender)이나 인종적 태생과 관계없이 배우고자 하는 학문적 자격 있는 학생들에게 공정하게 모든 기회를 제공하여, 미래에 공과 대학이 감소하는 비율이 작아지도록 하는데 필요한 프로그램이다. 넷째, 우리나라도 실업계 및 공과대학 인력 흡인책으로 PLTW와 같은 프로그램을 초ㆍ중ㆍ고등학교 교육과정의 도입을 검토할 필요가 있다고 인식된다. The purpose of this study was to investigate the Program which was made to enhance the national competitive of America through Pre-engineering eduction. PLTW(Project Lead The Way) of America is Pre-engineering Program to prepare engineering of the university, not as a regular school curriculum but as a Program offering basic engineering knowledge and occupation related with essential experience. The main contents of this study were consisted of introduction of PLTW, and to survey the Program of elementary, middle and high school of U. S. A and furthermore using the above results, we try to reasonably find the way to apply the U. S. A PLTW to our schooling system The main findings of this research were as follows: l) PLTW is the Program forming partnerships among Public schools, higher education institutions and the private sector to increase the quantity and quality of engineers and engineering technologists graduating from education system. 2) PLTW as Pre-engineering Provides basic training of engineering for 6-12 grade student(i.e., 6th grade of elementary school- 3rd grade of high school in Korea). This Program was made to give opportunity to the students who wish to enter to two-and four-year college or technical school. 3) PLTW was made to increase the number of students who wish to earn bachelor or associate bachelor of engineering, to fairly give equal opportunity to all the students regardless of gender and race who wish to study engineering field in the future, and then to make the rate of reduction of the application for engineering colleges less than before. 4) PLTW is also required for the our schooling systems in order to increase the application and technical high schools and engineering college in Korea.
How Stable is the Demand for Money in China?

Different authors have tried to estimate the demand for money in different countries. A common theme of almost all studies since 1987 is the application of cointegration technique. The demand for money in China is no exception and has received some attention by researchers. However, finding of cointegration has been interpreted as a sign of constancy of parameter estimates. In this paper we employ CUSUM and CUSUMSQ tests in conjunction with cointegration analysis to show that both M1 and M2 are cointegrated with their determinants. The results of stability tests reveal that while M1 money demand in China is stable, there is some doubt about stability of M2 money demand.
