이 연구에서는 고등학교 화학과 생물 교과서, 대학교 화학 및 생물 교재를 중심으로 삼투압과 반투막의 개념에 대한 설명 유형을 분석하였다. 연구 결과, 삼투압에 개념에 관련된 설명 유형은 대략 4개 정도의 유형이 있었으며, 반투막에 관한 설명 유형은 3가지 정도가 있었다. 특히 이러한 설명 유형 사이에는 시각의 차이가 있어서 같은 개념이 전혀 다른 현상으로 이해될 수 있는 경우도 있었다. 이러한 설명 유형의 차이는 학생들의 이해에 혼란을 가져올 수 있으므로 교과서 구성에서 재고할 필요가 있다고 본다.

Background: The purpose of this study was to evaluate the effects of power walking and square dancing on middle-aged women with hypertension. Design: Randomized controlled Trial. Methods: 30 middle-aged women with hypertension were selected and divided into two groups. 15 cases in the control group received routine treatment, and 15 cases in the intervention group received community vigorous walking and square dancing intervention on the basis of routine treatment. The intervention time was 40-60minutes/day, 5days/week, total 16 weeks. total cholesterol (TC), triglycerides (TG), high density lipoprotein cholesterol (HDL), low density lipoprotein cholesterol (LDL), angiotensin II (Ang II), Leptin, blood pressure, and heart rate were measured. Results: Body weight, body mass index (BMI), TC, TG, LOW-density lipoprotein, angiotensin II, leptin, systolic blood pressure and heart rate were significantly reduced after power walking and square dancing (p<0.05). After the experiment, TC and TG in the experimental group were lower than those in the control group (p<0.05), while HDL was higher (p<0.05). Conclusion: The results of this study suggest that power walking exercises and square dances are significant effects on lipid mechanism and heart rate.

Purpose: The most common cause of plantar ulceration is an excessive plantar pressure in patients with peripheral neuropathy. Foot orthosis and therapeutic footwear have been used to decrease the plantar pressure and prevent the plantar ulceration in in diabetes patients. We investigated whether protective sock with functional insoles reduce plantar pressure while walking in 17 diabetes patients. Methods: An in-shoe measurement device was used to measure the peak plantar pressure while walking. Peak plantar pressure data were collected while walking under two conditions: 1) wearing diabetic sock and 2) wearing the protective sock with functional insoles. Each subject walked 3 times in 10-m corridor under three conditions, and data were collected in 3 steps in the middle of corridor with in right and left feet, respectively. Pared t-test was used to compare the peak plantar pressures in three plantar areas under these two conditions. Results: The protective sock with functional insoles significantly reduced the peak plantar pressure on the lateral rearfoot, but significantly increased the peak plantar pressure on the middle forefoot, and medial midfoot (p<0.05). However, there were not significant in medial and lateral forefoot, lateral midfoot, and medial rearfoot between diabetic sock and the protective sock conditions (p>0.05). Conclusion: The protective sock with functional insoles reduced plantar pressures in the rearfoot and supported the medial longitudinal arch. However, it is necessary to change the position of metatarsal pad in the insole design of forefoot area to prevent diabetic foot ulceration.

This research is to know differentiation of CP(center of pressure) pattern among four pitching sort(straight ball, raise ball, change up ball, drop ball). Subject are three national or junior athletes. We use the one camera, Novel Win pressure measurement system. Conclusions are as follows : 1. When we throw the straight ball, CP of left foot is effective to end movement at middle of foot in body balance on arm angular motion and enhanced speed. 2. When we throw the raise ball, to change CP from middle to post is more effective in order to raise the ball. 3.In drop ball pitching, in order to fall down the ball in front of hitter, CP of left foot move from post foot to interior part of forefoot 4. In change up ball pitching, if CP of left foot move into forefoot, it is a cause of high ball and hitter can recognize the change up ball because of late arm rotation motion.

Purpose: This study examined the effects of the weight-bearing pattern and calcaneal taping on the heel width and plantar pressure in standing. Methods: Fifteen healthy subjects with normal feet participated in this study. The heel width was measured using a digital caliper, and a pedoscan was used to measure the plantar pressure of the rear foot while standing. The participants were instructed to stand in three weight-bearing patterns (anterior, middle, and posterior weight bearing) before and after calcaneal taping. The heel width and plantar pressure were measured three times before and three times after calcaneal taping, with the three weight-bearing patterns applied in random order. A 2 (non-taping vs. taping) × 3 (anterior, middle, posterior weight bearing) two-way repeated ANOVA with a Bonferroni post hoc correction was used to assess the differences in heel width and plantar pressure. Results: The results revealed a significant main effect of the weight-bearing pattern (p<.01), but not of calcaneal taping (p>.05). Greater weight bearing applied to the heel resulted in a significantly increased heel width and planter pressure of the rear foot (p<.01). Conclusion: In standing, a posterior weight-bearing pattern increases the heel width due to side-to-side shifting of the plantar heel pad, which increases the heel plantar pressure. Therefore, to prevent high stress on the heel pad and plantar heel pain, it is important to refrain from posterior weight bearing while standing during the activities of daily living.

For the purposes of analyzing the distribution and the change in blood pressure according to age and determining the factors affecting the change in blood pressure, a follow-up study had been conducted for 6 years from 1986 to 1991 for 430 primary school children aged 6 years old in 1986 in Kangwha County, Korea. The mean blood pressure increased according to age. Specifically mean systolic blood pressure increased from 97.3 mmHg for male and 96.4mmHg for female (at 6 years of age) to 108.8mmHg fur male and 112.1mmHg for female (at 11 years of age). Mean diastolic blood pressure increased from 60.0mmHg for male and 61.8mmHg for female (at 6 years of age) to 72.9mmHg for male and 73.8mmHg for female (at 11 years of age). The average annual increase in blood pressure was 2.3mmHg (in systolic blood pressure) and 2.6 mmHg (in diastolic blood pressure) for male : and 3.1mmHg (in systolic blood pressure) and 2.4mmHg (in diastolic blood pressure) for female, respectively. To determine the factors affecting the change in blood pressure, the stepwise regression analysis was conducted. Children were divided into the three groups(low, middle, and upper) according to the level of systolic and diastolic blood pressure at the age of 6, and the regression analysis was performed in each group. For the change in systolic blood pressure, the changes in weight and skinfold thickness or initial skinfold thickness fer male, and the change in weight for female were selected as significant factors for children in middle and upper group. For the change of blood pressure in diastolic blood pressure, no variables was significant.
