The purpose of this study was to analyze walking steps to prevent unnecessary energy consuming and prevention of injury from sliding when someone was walking. The questionnaire, high speed video system, E.M.G. system, and force platform system were used to analyze sliding mechanism in biomechanical perspective. Several results were found as following: 1. According to questionnaire regarding sliding, 93.3% of participants have sliding experiences. People have sliding experiences by greasy floor(48.4%) and obstacle (22.5%). Sliding types were found from different kinds of shoes such as sneakers (48.8%) and boots (34.2%). The results were presented as following 44.6% of participants were fall down front direction and 40.3% of people fell down rear side. 2. According to the high speed video system analyzer, step sliding increased with increasing step speed from distance and acceleration speed experiment with 80 steps/min, 100 steps/min, 120 steps/min. Also, the most sliding were occurred with sneakers, boots, and bare feet as order. 3. According to E.M.G. test results, the vastus lateralis M., the vastus medialis m., and the tibialis anterior m. of electric action potential presented strongly when participants fell front, rear, and right side. The vastus lateralis m. and the tibialis anterior m. of electric action potential presented strongly when someone fell left side, but the vastus medialis m. and the gastrocnemius m. of electirc action potential presented as weaker. 4. According to the force platform test results, the most big change of floor antipower of x-axis presented when someone fell the left side. The most of big change of floor antipower of y-axis presented when someone fell down rear side. The most of big change of floor antipower of z-axis presented similarly when someone fell the front, rear, left, and right side.

理 哲學의 두 가지 類型에 따른 倫理 思想과 自然觀

서은숙 한국국민윤리학회 2003 倫理硏究 Vol.54 No.1

중국 철학과 한국 철학에서 천지 자연의 생성 원리인 우주론, 즉 理氣論에는 전통적으로 超越觀的이기철학과 內在觀的이기철학이 있다. 주자와 퇴계의 超越哲學은 초월적인 理의 우선과 중요성을 강조하여 理一分殊와 渾淪·分開論을 주장하였다. 반 면 羅欽順과 栗谷의 內在哲學은 理氣混一論, 理氣渾淪無間說등을 들어 氣의 우선과 氣一分殊를 강조하였다. 초월 철학과 내재철학의 윤리사상에서, 초월 철학에서는 天理와 人欲을 대립시켜, 去人欲, 알인욕을 강조하여 人欲을 부정하였다. 내재 철학에서는 欲그 자체는 純惡이 아니라고 하였다. 이러한 내재관적 인성론은 율곡의 經世濟民觀으로 이어진다. 끝으로 自然觀에 대해서 초월 철학은 ‘理生氣’의 이론에서 천지자연과 인간의 공통적인 존재근거를 들어 사람이 천지의 중심이 된다는 인간의 존엄성를 밝힘과 동시에 모든 만물의 다양성과 평등성을 인정하는 자연관을 강조한다. 또한, 내재관은 氣의 절대성을 강조하여 ‘氣之全’을 강조하여 人과 物의 평등한 생성의 자연관을 볼 수 있다. 즉 두 철학은 모두 인간과 자연의 상보관계, 상관관계를 강조한다. Li(Li-Ch'i) Philosophy(Principle of the Universe Origin), cosmology in ancient chinese and korean thoughts, is divided into Li-philosophy(Transcendence philosophy, 主理論) and Ch'i-philosophy(Immanence philosophy, 主氣論). Chu Hsi(朱熹) and Yi Hwang(李滉) gave priority to Li(principle) and asserted that everything in the world has the unique universal principle. On the other hand, Lo Ch'in-shun (羅欽順) and Yi Yi(李珥) emphasized Ch'i(ether, matter) and contended that everything has its own characteristics and principle. Li-philosophy is in contrast to Ch'i-philosophy in the view of human desire; In the Li-philosophy, human desire is the opposite of the principle of universe, hence it is denied as what has to be restrained. On the contrary, in the Chi-philosophy, human desire is not the absolute evil. Yi Yi developed this perspective of human nature into the theory of warning public and governing people. In Li-philosophy of nature, Li creates and supports Ch'i. This 'Li-creates-Ch'i' theory enlightens human dignity in that it views human being as the center of the universe on the grounds that human being and the universal nature have the same basis of existence. At the same time, the view of nature in this theory emphasizes the variety and equality of all things in the universe. Ch'i-philosophy, where Ch'i is prior to Li and stresses the absoluteness of Ch'i, has a view of nature acknowledging the equality between human and matters. And in this point the two philosophies are the same in that both places an emphasis on the complementary and interdependent relationship between human and nature.

The purpose of this study is to determine the prevalence of obesity and to examine the eating habits of elementary school students in Iksan city. The study was carried out on 292 students(male : 151, female : 141) in May of 1997. The average height and weight of the subjects were 141 cm and 37 kg in males and 142 cm and 36 kg in females, which were similar to the average of Chonbuk. A Weight/Length Index(WLI), Broca Index, Ro¨hrer Index(RI), Body Mass Index(BMI) and Waist Hip Ratio(WHR) were used as an obesity index to classify degree of obesity, WLI, Broca Index and RI were proper for judging child obesity and strict judgments were conducted in the order of RI, WLI and Broca Index. The subjects were classified as 30.8% underweight, 43.5% normal, 8.2% overweight and 17.5% obese by WLI and there were significant differences between height (p < 0.05) and weight(p < 0.01) according to obesity degree among the four groups. 50.3% of the boys and 55.3% of the girls ate regularly, and the main reason they didn't eat breakfast(78.4%) was due to lack of time. The frequency of snacks were 1-2 times a week(40.4%), fruits(40.4%) from market and supermarket(68.2%). According to the survey 84.6%, 77.4%, 78.1%, 69.9%, 59.9% and 86.6% of subjects didn't eat meat, fish, soysauce, instant food, sugar and seaweed respectively. Seaweed, meat, and soysauce showed low preferences. 69.5% and 74.7% of the subjects drink milk and ate kimchi respectively. By analyzing eating habits according to the degree of obesity, the rate of skipping breakfast(p < 0.01), and eating meat or fish(p < 0.05) were high in the overweight and obese groups of girls. In the boys case, the rate of not eating food in sugar(p < 0.05) was high in the obese group. Obese children need to correct their eating habits. This reasserts the importance of nutrition education in children through teachers, parents, and dietitions. The findings of this study may be applied to nutrition education to ensure better physical fitness for children.

Objectives : This research is to test anti-cancer effect of kyungohkgo (sample 1) and modified kyungohkgoes (sample 2 and sample 3) when they prescribed to mice that translate a 3LL lung cancer cell. A sample 1, 2, and 3 are prescribed for the 1st, 2nd and 3rd group, respectively. Methods : Inoculate mouse lung carcinoma cells to a BDFI mouse and did an experiment about tumor occurrence periods, body weight, tumor volume, survival rate, life prolongation. Results : The development time of tumor lump to the 3rd group is latest as 181.71±18.88 hours. That is, it means that a lung cancer of this group was induced latest. In tumor size, the 3rd group is also fewest by 1,536~9,375㎣. The tumor growth rate of the 3rd group appeared lowest by 610.35 percent. Only the 3rd group was appeared that has a control effect of tumor growth. Also, 3 mice of the 3rd group were survived for 30day after translating the lung cancer cells. The survival extension rate of the 3rd group was highest by 38.39 percent. Conclusion : In these experiments, it appears that the sample 3 prescribed by modified kyungohkgo has the highest anti-cancer effect. It is proved that the modified kyungohkgo affects the 3LL lung cancer cell by acting complexly.

Purpose: to evaluate the usefulness of the panoramic radiography, generally used in dental clinic, for the detection of the maxillary sinus pathosis due to the inflammation and tumor, through the comparison with CT findings as the absolute standard. Materials & Methods: 150 maxillary sinuses of 75 patients with or without particular signs and symptoms and showing soft tissue lesions or destruction of maxillary sinus walls in at least one sinus in CT, were selected as subject samples, and the panoramic radiography of the same patients were interpretated by 3 dental radiologists and 3 non dental radiologist given no previous informations. Using the CT findings as the absolute standard, the diagnostic ability of panoramic radiography in the mucosal thickening, maxillary sinus haziness, inferior wall destruction, medial wall destruction, posterolateral wall destruction and the superior wall destruction was evaluated using the ROC curve and the difference between dental radiologist group and non dental radiologist group was also evaluated. Results: 1. When dental radiologist group interpretated the destruction of inferior wall and posterolateral wall, the kappa value which shows interobserver's coincidence was above 0.75. 2. The diagnostic ability according to site of interpretation was the highest when the inferior wall was interpretated in both observer groups and there was a statistically significant difference between the dental radiologist group and non dental radiologist group in interpretating the mucosal thickening, haziness, destruction of the inferior and medial wall(p<0.05). 3. The diagnostic ability in detecting the destruction of the sinus walls was better than in soft tissue lesions in both groups and between the groups there was a statistically significant difference(p<0.05). Conclusion: When detecting the destruction of inferior and posterolateral wall of the maxillary sinus there was coincident with that of CT findings, and so it is considered that diagnostic ability of panoramic radiography is high in this point. But in interpretating the destruction of medial wall and soft tissue lesions, diagnostic ability of the panoramic radiography was relatively low and there was a significant difference between the dental radiologist group and non dental radiologist group. Therefore CT or other auxiliary diagnostic method will be necessary when evaluating thorough pathosis of maxillary sinus objectively.(J Korean Oral Maxillofac Radiol 1999:29:221-237)

Purpose : The purpose of this study was to investigate relationships among family support, self-care, and quality of life of patients with arthritis through a survey. That will be basic data to plan nursing intervention for promoting quality of life for patients with arthritis. Method : The convenient sample of this study consisted of 120 patients with arthritis and data were collected using questionnaires during August 2006 from two OPDs of rheumatoid centers in C University hospitals. The study instruments were used to measure Self Care (So, 1992), Family Support (Kang, 1984), and Quality of Life (Ro, 1988). The data were analyzed using ANOVA, Duncan test, and Pearson correlation. Result : The mean scores were 3.56 for family support, 4.16 for self-care, and 3.19 for quality of life. The level of self-care was significantly higher in those men, having an occupation, higher income, and living with family members. The level of family support was significantly higher in those men, having an occupation, living with family members, and having a helper. The level of quality of life was significantly higher for those men, having a higher income, and shorter length of illness. Three relationships were found to be positively correlated: 1) between the levels of family support and self-care (r=.53), 2) between the levels of self-care and quality of life (r=.55), and 3) between the levels of family support and quality of life (r=.54). Conclusion: Therefore, a nursing intervention program needs to be developed to promote family support, and self-care for quality of life for patients with arthritis.

Purpose : To determine normal CT number range of parotid gland by analyzing the change by age increase and the difference among individuals and between both sexes in CT number of normal parotid gland. Materials & Methods : 134 subjects who took the CT scan between the period of Jan. 1996 and Dec. 1997 at Yonsei University, Dental Hospital were selected. Criteria for selection were that the patients must be within the normal range clinically and radiologically, and the entire parotid gland on the axial view must be shown. Among the axial views, the one showing the greatest parotid gland size was selected and its CT number was recorded. Also, CT numbers from both masseter muscle were recorded as its control. Results : There was statistically significant correlation between CT number of right and left of parotid glands and masseter muscles. With the increase of age, there is a significant decrease in the CT number of parotid gland(p<0.05). There was no statistically significant difference in CT number between sexes except the 7th decade and beyond age group of parotid gland(p>0.05). Conclusion : As age increases, CT number of parotid gland has a tendency to decrease, and there is no significant difference in the CT numbers between left and right parotid gland. Therefore in the CT scan of patients suspected of having a salivary gland disease of the parotid gland, to consider normal range of the age-dependent CT numbers of parotid gland and compare the CT numbers of the right and left parotid gland might be useful in diagnosing the disease.(J Korean Oral Maxillofac Radiol 1999;29:451-458)
