  • 본 연구는 한국기업들이 기업자산을 제 3자 혹은 신설기업으로 탈퇴시키므로써, 즉 자산, 제품생산라인, 자회사, 사업부 등을 현금, 증권 등으로 교환하므로써 발생된사건, 특히 자산중 영업일부를 양도한 기업에 있어 주가수익율의 영향을 분석하고자 한다. 분석결과 영업일부를 양도한 기업들은 (+)의 평균초과수익율을 얻는 것으로 나타났다. 이것은 한국증권시장에서 영업(營業) 일부양도(一部讓渡)가 양도기업 株主(주주)의 부(富), 즉 주식(株式)의 시장가치에 정(+)의 영향을 미친다는 것을 의미한다. 그리고 영업 일부양도 후 후속 재무구조 개선집단과 악화 집단간의 시장반응에 있어 악화집단이 오히려 더 큰 정(+)의 시장반응을 보이며 유의적인 큰 차이가 존재했으며, 또한 후속 EPS 증가집단과 EPS 감소집단에 있어서 후속 EPS 증가기업이 더 큰 정(+)의 시장반응을 보이며 유의적인 차이가 존재했다. 이러한 사실로 미루어 볼때 영업(營業) 일부양도(一部讓渡)는 투자자들에 의해 재무구조개선 및 비수익성 영업일부의 양도를 통한 기업수익성(企業收益性)의 증대라는 관점에서 크게 받아들여 지고 있다는 것을 암시해 준다.

For this purpose, twenty subjects were participated in this study and the participants were 'After School Class' boys in B middle school located in Gimhae City. They divided into exercise group(n=10) and control group(n=10). Exercise group conducted 45minutes per a day, four times a week for 12 weeks. And the control group continued their normal life. The results were as follows; First, in exercise group, lean body mass, muscular strength, muscular endurance, cardiovascular endurance and flexibility were all significantly increased after program execution. But %body fat was significantly decreased. In control group, muscular strength, muscular endurance and cardiovascular endurance were significantly increased. There were significant differences in lean body mass, %body fat, muscular strength and flexibility between two groups after program execution. Second, in exercise group, HDL-C was significantly increased after program execution. In control group, TG was significantly decreased. But HDL-C was significantly increased. There were no significant differences in all blood lipids(TC, TG, HDL-C and LDL-C) between two groups after program execution. Third, in exercise group, GH and IGF-I were significantly increased after program execution. In control group, IGF-I was significantly decreased. There were significant differences in IGF-I between two groups after program execution. These results indicate that music rope-skipping is effective to improve lean body mass, muscular strength, flexibility, GH and IGF-I in normal middle school male students.

  • The purpose of this study was to explore the characteristics of defining concrete and abstract nouns for the elderly. A total of 382 elderly participated in this study and they were classified into four age groups (i.e., over 55 to under 64, over 65 to under 74, over 75 to under 84, and over 85 year-old group). They performed the word definition task, composed of five concrete and five abstract nouns. The total scores and numbers and ratio of core/supplementary meanings were compared among four elderly groups. The frequency and ratio of error types were also examined. The results showed that all four groups had statistically significant differences in total scores, numbers and ratio of core and supplementary meaning of concrete noun definition task. In addition, abstract noun definition performances revealed group differences except the two groups (over 75 to under 84 and over 85-year-old group). The oldest group showed a sharp increase in error production. The highest ratio of error types were personal experience in over 55 to under 64-year-old group, and over 65 to under 74 year-old groups; and for the target word repetition in over 75 to under 84 year-old group; and no response in over 85 year-old group. In conclusion, both concrete and abstract word defining abilities had age-related deterioration. This decline results from impairment in spreading semantic knowledge within semantic network, which is vulnerable to aging. Characteristics of word definition for elderly can provide basic information to understand various neurolinguistic disorders associated with age.

  • This study investigated the influences of reciprocal peer tutoring (RPT) strategy on middle school students' science achievement, self-efficacy, perception of instruction by grouping method and science achievement level. Eighth graders from a middle school in Seoul were assigned to comparison, homogeneous RPT, and heterogeneous RPT groups. The students were taught about 'separation of mixtures' for 8 class hours. After the instructions, a science achievement test consisting of three subtests (knowledge, understanding, and application), a self-efficacy test, and a questionnaire about the perception of instruction were administered. The analysis of the results revealed that the scores of heterogeneous RPT group, regardless of the students prior science achievement level, were significantly higher than those of the other groups in the knowledge and understanding subtests, and the self-efficacy test. The scores of homogeneous RPT group were significantly higher than those of the comparison group in the knowledge subtest but not in the understanding subtest and the self-efficacy test. The low-level students in heterogeneous RPT group performed better in the science achievement test and the application subtest than those in the other groups. The high-level students in RPT groups performed better in the science achievement test than those in comparison group. However, there was no significant difference for the application subtest scores of the high-level students of the three groups. Most students in RPT groups perceived positively on the instructions. The students in heterogeneous RPT group and low-level students especially showed more positive perception of the instruction than those in homogeneous RPT group and high-level students.

  • The goal of this study was to investigate the differences in the effect of feedback from different providers on elementary school students' science achievement and to examine the responses of the students regarding the feedback. Three 6th grade classes were chosen to be assigned as experimental group 1, experimental group 2, and control group, respectively. In experimental group 1, the teacher provided feedback with students concerning the formative evaluations which were conducted periodically. Experimental group 2 was the one in which students were organized into small groups to compose and exchange feedback with one another. No feedback was of offered to students in the control group. The results of the science achievement test indicated ,that the provision of feedback by the teacher resulted in more gains in student academic achievement. The interviews with students revealed that the learners made positive responses to the feedback provided by the teacher while they showed negative attitudes toward the feedback exchange among students. There were also differences in student responses to feedback between high and low achievers in science. Implications for science lessons and science education research were presented and discussed.
