As domestic recession has had an adverse impact on many Korean companies in Korea, financial soundness has become a critical issues. It is essential to identify financial risk factors to prevent workout as well as to improve the financial condition of domestic construction companies. Therefore, this study derived important management indicators and the financial ratios that belong to each indicator through a comparative analysis between healthy companies and workout companies with financial statement. As a consequence, key financial ratios are derived into 3 of 25 ratios; Equity Ratio in stability indicator, Total Asset Turnover Ratio in activity indicator, and Labor Equipment Ratio in productivity indicator. So, Korean construction firms are required close monitoring these critical financial ratios indicating variation between construction companies which have opposing statuses in finance in order to keep sound financial condition and increase productivity.

This study was carried out to find the problems of assessment on terrestrial ecosystem part in environmental impact analysis(EIA) and to suggest the proper amelioration measures by analyzing 19 environmental impact statements(EIS) published during the period from 1991 to 1994. The results obtained from this study were as follows. Field survey for the investigation of fauna and flora in project areas should be conducted at least 3 times a year and name of investigator should be written on the EIS clearly. Increase or decrease in degree of green naturality and productivity cannot be an absolute criteria for expressing the amount of changes in ecosystem. Evaluation for the ecosystems and their composition in project area is more important than presenting merely the increase or decrease in degree of green naturality and productivity. Alleviation measures in 19 EISs analyzed in this study were summarized into 6 types: They are establishment of landscape plan, transplanting of useful trees preservation of big tree and protected species, restoration and preservation of existent vegetation, establishment of soil conservation measures and diminution of the impact on animal. However, they were somewhat insufficient because they wouldn't suggest the alleviation measures in detail. The more positive counter-proposals are needed to decrease the impact of the project on terrestrial ecosystem.

Noise of automotive alternators can be classified into mechanical noise, aerodynamic noise and electro-magnetic noise. which is the same as for electric motors. Previous studies show that the elect ro-magnetic noise takes a maw peak at the rotating frequency multiplied by the number of stator slots. It has not been proved clearly so far, however, that the major peak is wholely due to the stator slots. On the contrary it is well known that noise of motors. which has a mechanism similar to the alternator except that the number of stator slots in automotive alternators is in gene\integer multiple of that of rotor segments, is closely related to the number of rotor slots. Therefore, the statement that only the stator slots is the source of the major peak in the noise spectrum of alternators is suspicious although not easy, to show theoretically, that the statement is incorrect. In this paper. effects of the stator slots on the noise in an automotive alternator are experimentally investigated by intentionally modifying the number of stator slots in such a way that the number of the states is not an integer multiples of the rotor slots. It is shown that both the stator slots are not so much influential as the rotor slots and claimed that the major peak in the noise spectrum of conventional alternators is due to superposition of a component caused by the stator and a higher harmonic component caused by the rotor

The purpose of this study was to examine the reliability of Q-sorting and to develope a typology of coping to stress in school-age children through the use of Q-methodology. For the study, Q-statements are selected from the literature and interviews of 30 Children, A total number 153 statement were collected and 31 Q-samples were finally selected. AP-sample of 76 was selected the elementary school children. Each of respondents were given 31 coping strategies questionnaire and set of 31 statements with cartoon on each of cards and sorted them according to the 9-point scale. The result of the C-sorting by each subject were coded and analyzed using the QUANAL PC and SPSS PC＋ program. As a result of the analysis, There were significant relationship between score each item of question naire and score of sorted statement. Therefore, school-age children was able to Q-sorting(forced normal distribution). Also, the four types of coping were named as follows : Type I (n=35) : To search for the dynamic behaviors Type II (n=12) : To search for the intellectual behaviors Type III (n=22) : To search for emotional-spiritual behaviors Type IV (n=7) : To search for the self-abuse behaviors Throught the study, the implication for teachers, parents and school nurses is that there is needed to guide and to support adaptive coping behaviors. Also, it is recommended that the application of Q-methodology for study of children's subjective concepts like stress and coping.

우리나라 기업들은 허근 경제 위기를 겪으면서 대외적으로 커다란 환경변화의 요구에 직면해 왔다. 사실 이러한 변화요구는 굳이 경제 위기가 아니라 할지라도 치열한 생존경쟁에 있는 현대의 기업들에게 있어서는 필수요소라 할 수 있다. 이에 대응하여 기업들은 구조조정, 혁신, 조직개선 등의 이름으로 다양한 변화노력을 기울이고 있지만 이와 같은 변화의 노력에 대해 그 진행과정이나 결과에 대해서는 현명한 검토가 있어야 할 것이다. 즉, 기업의 성장에 도움이 되지 않는 조직 구조는 오히려 기업에 역효과로 작용하게 되므로 기업은 가치를 높일 수 있는 조직구조를 갖추어야 한다. 이차 같은 현상은 일부 기업에게만 국한되는 것이 아니라 건설기업에도 마찬가지로 적용됨 수 있다. 따라서 본 연구에서는 효율적인 조직구조를 갖추기에 앞서서 건설 기업의 조직구조를 전략 및 경영성과와 비교${\cdot}$분석하여 조직의 특성을 파악하고자 한다.

This study is to consider hypotheses with integral view on the respect of creative thinking. Subjects of this study are Korean students in the 5th grade who participated in the Field Trip Contest of the second Korean Youth Science Festival, an openended inquiry investigation. Objectives of this study are as follows: 1) to measure the inquiry level of the Field Trip Contest activity 2) to find how many hypotheses were made on different types in the inquiry investigation 3) to measure the quality level of hypotheses made in the scientific inquiry investigation 4) to find out the correlation between the 1st and 2nd hypotheses and the final activity score in the two staged scientific investigation In the consequence of it, inquiry level of the Field Trip Contest was very high with good activity topics and openended way of investigation. Hypotheses were made in the prediction, plan, and conclusion parts in the field trip activity report. They used hypothesis-as-prediction typed statements(3.41/team) more than hypothesis-as-explanation(1.28/team) and descriptive hypothesis(0.03/team) types. Content-related hypothesis(5.03/team) and process-related hypothesis(6.16/team) were usually coupled each other. Most of them had difficulties in hypothesis-from-evidence(0.31/team, 10/32 teams) in the comparison of hypothesis-from-simple conjecture(10.62/team). The quality level of content-related hypotheses(0.74point/statement) and process-related hypotheses(1.98point/statement) were very low by the hypothesis-quality scale(Quinn and George, 1975) for the content-related hypotheses and the process-related hypothesis quality scale developed in this study. There was considerable correlation between the activity score and the 1st and 2nd hypothesis in the 2 staged inquiry investigations with the 2nd and 3rd topics($0.41{\ast}$, $0.59{\ast}{\ast}$ repectively).

광고나 세일즈 등 마케팅 현장에서는 제품이나 서비스의 사용방법을 설명하거나 목표 달성을 위한 절차를 알려 주고 특정 행동의 유도 또는 금지의 내용을 담기 위해 명령문을 자주 사용한다. 본 연구는 특히 지시적 명령문과 설명적 명령문에 대해 시간 지평 관점에 따른 행동의도와 기억의 양상에 주목하였다. 실험 결과, 생의 남은 시간을 짧게 느끼는 노년층이 보다 정서적인 측면에서 정보를 접근하기 때문에 부정의 감정을 더 느낄 수 있는 지시적(vs. 설명적) 명령문에 대해서 거부감을 느끼고 이에 따른 행동의도 저하가 왔다. 그런데 지시적 명령문이 유발하는 부정적인 정서는 노년층에게 있어 이러한 정서를 유발하는 정보의 현저성을 높여 오히려 기억은 상승시켰다. PROCESS 분석 결과, 명령문에 노출되었을 때의 감정이 이 같은 결과들을 매개하는 것으로 나타났다. 이러한 결과는 명령문의 진행에 있어 행동적 반응과/또는 정보처리의 성과를 향상시키기 위해서는 수용자의 나이를 심도 깊게 고민해야 하며, 또한 어떤 방식으로 명령문을 구성할 지도 고려해야 함을 보여준다는 데 의의가 있다.
