        The stature, span, lower limb length, sitting height, head length and head width of 430 Korean elementary school boys ranging from 7 to 10 years of age were measured biometrically and the indices among all of the items in each age group were calculated to investigate the physical growth status and the indices between physical measurements. The following conclusion have been obtained. 1. The average statures were 117.59±0.42cm in 7, 123.96±0.46cm in 8, 128.54±0.57cm in 9 and 132.13±0.49cm in 10years of age group, and the annual average stature growth was 4.85cm. 2. The average spans were 114.00±0.45cm in 7, 119.83±0.48cm in 8, 126.06±0.59cm in 9 and 129.62±0.51cm in 10 years of age group, and the annual average span growth was 5.21cm. 3. The average lower limb lengths were 62.58±0.29cm in 7, 66.79±0.31cm in 8, 70.07±0.36 cm in 9 and 72.46±0.32 cm in 10 years of age group, and the annual average lower limb length growth was 3.29cm. 4. The average silting heights are 65.08±0.25cm in 7, 68.89±0.25cm in 8, 71.26±0.30cm in 9 and 72.52±0.27cm in 10 years of age group, and the annual average sitting heights growth was 2.24cm. 5. The average body weights were 21.58±0.20kg in 7, 24.75±0.34kg in 8, 27.56±0.41kg in 9 and 20.80±0.40kg in 10 years of are group, and the annual average body weight growth was 2.41kg. 6. The average head lengths were 16.47±0.05cm in 7, 16.75±0.06cm in 8. 16.68±0.06cm in 9 and 16.82±0.07cm in 10 years of age group, and the annual average head length growth was 0.12cm. 7. The average head width are 14.99±0.06cm in 7, 15.17±0.05cm in 8, 15.31±0.06cm in 9 and 15.26±0.05cm in 10 years of age group, and the annual average head width growth is 0.09cm. 8. While the indices of both relative span and relative lower limb length were increased with age, the indices of the relative sitting height were slightly decreased with age. The fact that while the indices of the relative lower limb length were increased with age, the index of the relative sitting height was decreased, indicated that the growth of the lower limb length affects greatly on the stature of growth by surpassing the trunk growth. 9. The relative body weight also increased with age. This fact suggested that not only the stature growth but also the development of internal organs and muscles are remarkable with age. 10. The head type depended on cephalic index was belonged to ultrabrachyoephal, and showed no differencies with increasing age in all groups.

      • 國家責任制度硏究

        韓昌奎 成均館大學校 1962 論文集 Vol.7 No.-

        My subject of this investigation is the civil liability of Governments, both within the Continental Europe, and Anglo-America. To write a thesis on the substantive Law of Countries other than my own is a rash venture, and I hope therefore that readers especially will be charitable. As contents show, I had investigated the Governmental Liability within the historical and substantive field of vision in comparative survey. German states could be sued for breach of Contract, as fiscus. But the fiscus could not then be sued for governmental acts. Only the fiscus could be sued and then, always according to private law in the civil courts, throughout the nineteenth century. Until the nineteenth century France, in common with the rest of Europe, denied any State responsibility, so all-pervasive were the notions of divine right of Kings and sovereignty. Afterwards, Actes d'autorite´, for which there was no civil liability, included legislation, adjudication, execution of the laws and such other governmental acts as could not be performed by a private citizen. Liability for the remaining administrative acts, actes de gestion, was on the other hand, favoured. It was tempting to equate the distinction with that between public and private law, and to hold that liability for all actes de gestion should be determined according to the Civil Code. In 1873, the famous Blanco Case is the great turning point in French administrative law. And the Conseil d'Etat, not bound by any code, was free to build up special rules of Administrative liability. And it gradually extended the responsibility of the State. In Japan, America, England, there was no right to sue the State in Actes d'autorite´ until 1945, 1946, 1947. The above show that the royal immunities, both substantive and porcedural, originated in a feudal background as prerogatives personal to the King. Immunity was reinforced by theories of divine right of kings and of sovereignty, e.g. as shows the maxim "the Kings can do no wrong." But the increasing interference by the State with the activities of the citizen made some alteration in the legal position of Anglo-American Governments inevitable. So they made the law, such as State Damage Law, Crown proceedings Act, Federal Tort Claims Act, after World War Ⅱ. This comparative survey of the field of State liability shows that the Law of State Damages of Korea has made a good contribution to the reconciliation of the freedom of the individual and the authority of the State. But that conflict of authority and freedom which now confronts democracy has not yet ceased. The lawyer at least should not fail to keep freedom of individual. I am grateful to professor, Do Chang Kim who so patiently and helpfully taught my queries. I am particularly indebted to my professor, Il Kyung Park, M. Y. Kang, for their guidance at my academic life. Finally, I have to make a promise to study harder than before.

      • 고속가공용 엔드밀 형상설계 S/W 개발

        한창규,고성림,서천석,김경배 한국공작기계학회 2004 한국공작기계학회 추계학술대회논문집 Vol.2004 No.-

        The tool geometry parameters and cutting process have complex relationships. Until now, various cutting test were needed to acquire optimal design of end mill for the purpose of high speed machining, due to the insufficient knowledge about cutting process in high speed machining. Using various tools with different geometry, relationships between tool geometry parameter (rake angle, clearance angle, length of cutter) and cutting process (cutting force, surface accuracy, surface roughness) have been studied. Acquired data can be used to design optimal tool for high speed machining and to develop a software for design of end mill geometry.

        Effect of superoxide on the development and maintenance of mechanical allodynia in a rat model of chronic post-ischemia pain

        한창규,한재경,박기범,곽경화,박성식,임동건 대한마취통증의학회 2012 Korean Journal of Anesthesiology Vol.63 No.2

        Background: Reactive oxygen species and inflammatory responses contribute to the development of neuropathic pain. Superoxide serves to mediate cell signaling processes and tissue injury during inflammation. We examined the effects of superoxide on the development and maintenance of mechanical allodynia, as well as its contribution to central sensitization in a superoxide-rich animal model of neuropathic pain. Methods: Chronic post-ischemia pain (CPIP) was induced via the left hindpaw ischemia for 3 h, followed by reperfusion. Superoxide dismutase (4,000 U/kg, i.p.) was administered either 5 min before ischemia (BI), 5 min before reperfusion (BR), or 3 days after reperfusion (3AR). Withdrawal thresholds of the four paws were measured to assess the mechanical allodynia and the effects of circulating xanthine oxidase (XO)-mediated superoxide production. In addition, we measured the levels of N-methyl D-aspartate receptor subunit 1 phosphorylation (p-NR1) in the ipsilateral and contralateral spinal cord (L4-6), by Western blotting, to examine the superoxide-mediated central sensitization. Superoxide production was assessed by allopurinol-sensitive, XO-mediated lipid peroxidation of the spinal cord and gastrocnemius muscles. Results: Withdrawal thresholds of forepaws did not vary across the 7 days of testing. In the hindpaws, both ipsilateral and contralateral mechanical allodynia was most attenuated in the BR group, followed by the BI and 3AR groups. The degree of NR1 activation was in contrast to the changes in the withdrawal thresholds. Conclusions: These data suggest that superoxide is involved in the development and maintenance of mechanical allodynia, particularly via central sensitization in the spinal cord.

        한창규,황규윤안규동,이병국 순천향대학교 산업의학연구소 1996 순천향산업의학 Vol.2 No.1

        To obtain the prevalence rate of health related symptoms of white collar workers who were not exposed to hazardous agent and to investigate the relationship between subjective symptoms & health related variables, 11,266 subjects who were employed for government organization & private educational institute in Seoul, Chungnam, Kyungpook area were studied in order to provide basic information for the health management of white collar workers. All th subjects visited hospitals to take biannual health examination provided Medical Insurance Association for the purpose of screening of several important adult disease. Todai Health Index(THI) questionnaire which is modified questionnaire of CMI made by Todai was selected for the questionnaire form of this study. During hospital visit for health examination, Todai Health Index questionnaire of 88 questions were filled up by the subjects themselves and confirmed by medical doctor. Major findings obtained were as follows: 1. The abnormal rate of screening test was 22.7% in male, 8.5% in female, and 19.2% in total subjects. The prevalence rate of disease was 13.2% in male, 4.9% in female & 10.9% in total subjects. 2. The prevalence rate of all diseases increased by age and th prevalence rate of male subjects were higher than female subjects in all age categories except that of the anemic disease. 3. While highest prevalence rate in all subjects was observed in cardiovascular disease(4.8%), the prevalence rate were 3.4% in liver disease, 2.0% in diabetic disease, 1.9% in pulmonary tuberculosis & chest disease, 0.5% in kidney disease and 0.4% anemic disease. Liver disease was more frequent in age group of below 29 years old and age group of 30-39 years old, but in older age groups(40-49 years old, above 50 years), cardiovascular disease was most frequent. 4. The highest mean score of THI symptom category was mental instability and the lowest one was skin & anus symptoms. The most frequent symptom of THI was "think a lot before action" in nervousness symptom category and mean scores of the female subjects in all symptom category were higher that those of male subjects. 5. In symptoms and signs of recent 3 months, the most frequent symptom and sign was "generalized fatigue" and mean score of it was 1.85. Multiple comparison analysis of health related factors revealed that "illness in health status" was the highest score(23.54) in male and sometimes drink & drunken in alcohol intake was th highest score(26.13) in female. 6. In multiple comparison analysis, health related factors such as health status, health management, diet habit, taste character, vegetable intake, coffee & beverage, alcohol intake were found to be associated with th overall THI symptom category in both sex and age and smoking in male, type of job in female were associated THI symptom category. 7. In stepwise multiple regression analysis of mean score of THI symptom category(dependent variable) and health related factors(independent variables), the variables of health health status, taste character and alcohol were contributed to THI symptom category in order and the highest correlation coefficient(r) was 0.4085 in male and 0.397 in female in health status of mental instability. 8. The significant health factors contribution to THI symptoms score in male subjects were, in multiple regression analysis with THI symptom category with dependent variable and health related factors with independent variables, health status, diet habit, alcohol intake, taste character, final diagnosis, coffe & beverage, type of job, age, smoking, health management, meat intake and in female were health status, type of job, diet habit alcohol intake, coffee & beverage consumption, screening test, age, health management. The most significant contribution factor among health related variables was health status in over all THI symptom category.
