This study investigates the influence of cane length on the weight distribution of the elderly in a standing position. Thirsty participants were evaluated using two different cane lengths based on measurements of distal wrist crease to ground (WC cane), and distance of greater trochanter to ground (GT cane). A limloader was used to determine the weight distribution on the subject. It was found that 6.5% of body weight was supported on a GT cane and 7.7% of body weight supported on a WC cane in a standing position. Results suggests that more weight is distributed on a WC cane than a GT cane in the elderly.

We tested fruits quality and skin coloration of two pear cultivar ‘Wonhwang’ and ‘Whasan’ produced by bagging with different kinds of paper bags in the Cheonan area, Chungnam Province, Korea. The fruits were bagged at 35, 45, 55 or 65 days after full bloom (DAFB) with 3 kinds of double layer paper bag which consisted of grey color, yellow color and newspaper for outer layer. The great extent of light interruption was observed in grey colored outer paperbag among three kinds of paperbag which showed only 0.46% of lowest light transmittance when compared with 43.7% and 40.0% of yellow paper and newspaper, respectively. The development of skin redness (a*) increased with the delay of bagging time in two pear cultivars. But the fruits treated at 65 DAFB showed uneven coloration and excessive development of redness which represented low fruit external appearance value. Uniform flesh firmness was attained at the fruits bagged with grey outer color paperbag regardless of bagging time, although the fruit quality indices including soluble solids and titratable acidity did not change significantly by using different kind of fruit bags and bagging time in two pear cultivar. Based on our results, it was explained that the grey-colored fruit bag had positive effect on the development of skin coloration without any detrimental effect on fruit quality factors in ‘Wonhwang’ and ‘Whasan’ pears.

The purpose of this research is to assess and understand the health conditions and lifestyle patterns of babies and toddlers who attend preschool and childcare centers in small and mid-sized cities, and provide structure and criteria for implementing the fundamental elements for early childhood education and development. A sample population focused on those attending preschools and child care centers in the Gimcheon area were assessed on June 20 through July 5, 2011 by means of questionaires. These children's health results were found to be higher than the national standard for normal 3, 4 and 5 year old children's health development. Findings also showed there was no difference in the level of partic-ipation in health fitness programs among mothers who held different vocations. This research showed that more children were going to childcare centers per year, which came out to be about 12.77 times more than preschool, which had a slightly lower number of 11.81 times. A slighter higher number of the children attending preschool had mothers who were stay-at-home moms (precisely 12.23 times more) as opposed to those whose mothers worked (11.19 times). Lastly, results showed that the children of mothers who did not work had a higher percentage of eating breakfast rather than those children whose mothers worked.

오재철,김회옥 順天大學校 1997 論文集 Vol.16 No.1

I develop CAI program using the study of sequential and non-sequential theory and apply it to a instruction - learning course. I studied and estimated second year's students of K middle school in Kohung county. In the result of study it is presented that we need to increase application ability through being composed of interesting problem's solving in the understanding degree of learning content. A precise constitution of prelearning needs in the analysis relevant to learning way and CAI class. On the one hand the making under the condition of understanding learning environment precisely in response degree of CAI class. In case a learner replies a wrong answer the hint and complementary explanation relevant to a right answer reorganize the knowledge constitution of feedback which is supplied. So it shows there is the effect of repetitive learning.

In this study, an analytical procedure was evaluated for the determination of atmospheric PAH, both in gaseous and particulate phases. The method involves Soxhlet extraction of the filters and Tenax adsorbent, followed by a clean-up stage using a silica mini column prior to analysis by reversephase HPLC with wavelength programmable fluorescence and UV detection. A total of 18 PAH were identified and quantified, all of which have been of environmental concern. In order to validate the methodology and to ensure compatibility of the results, the analytical method used for the determination of PAH was evaluatd with respect to the efficiencies of extraction and clean-up procedure, HPLC separation, and lower limits of detection. In addition, substrate dependency of PAH recovery was also investigated for the two type of filter(glass fiber and PTEF filters) and Tenax adsorbent.

이 연구에서는 세종시 건설과정의 마을공동체 갈등요인을 분석하고, 갈등에 대처하는 주민들의 대응 행태분석을 하는데 목적이 있다. 즉 세종시 건설이라는 국책사업과 관련된 농촌지역의 작은 면단위 행정구역 안에서 주민들의 의견이 어떤 영향을 받아서 대립하게 되었는지 대립 양상은 어떠하며, 개인적 인식 차이에 의해서 대응 행태는 어떠한 영향을 받게 되는지 분석한 결과, 갈등당사자의 개인적 인식에 따라 갈등 대응 행태가 다른 것으로 나타났다. 예를 들면, 개발이익 증대를 예상하는 사람일수록 세종시 편입에 찬성 정도가 강하였으며, 세금증가를 예상할수록 편입을 반대할 것이라는 부의 상관관계를 보였다. 지가상승을 예상할수록 그리고 청주․청원 통합에 찬성할수록 세종시 편입에도 찬성하는 것으로 조사되었고, 지역자부심이 클수록 세종시 편입에 반대한다는 상관관계가 있음을 밝혔다. The purpose of this paper is to analyze the factors of conflicts related with the Construction of Sejong Special Autonomous City in Korea. For accomplishing the research goal, this study conducted a questionnaire survey and empirical analysis on conflict behavior. According to the results of analysis, the types of conflict coping behavior was significantly different for all the causes of conflict except the absence of support and cooperation system. This suggests that a conflict situation is characteristically affected by multiple causes and people’s perception of the causes is different among individuals, and therefore, any single method cannot be used alone for conflict management. Not only for national projects but also for any projects causing conflicts, there are many factors influencing such conflicts in addition to demographic characteristics and personal perception as presented in this study, and these factors work not separately but compositely. Accordingly, it is necessary to approach the management of conflicts from a comprehensive viewpoint and, at the same time, fitting for the characteristics of individual situations.
