Regulation of Ca^++ channels across cell menbranes can be dramatically altered by ischemic states, and such agents relates to cytotoxic effect. The genration of free radicals in ischemic tssue is detrimental to survive of that tissue. If intracellular calcium increasement and free radical production can be blocked or scavenged, tissue damage should be minimized. In the concept of above theory, the author studied the effect of nifedipine. α-tocopherol known as a calcium channel blocker and hydrohobic scavenger on the random pattern skin flap survical of white rats . Sprague-Dawley rats(N-60) were divided into four groups of control(no medication) , nifedipine(10㎎/ ㎏ /day, I.M.), α-tocopherol(20㎎/㎏/day, I.M.). nifedipine plus α-tocopherol. All of medications were given for 11days from 4days before flap elevation and contnued for 7days after flap elevation. When flap survival rates were measured. Flap tissue was obsered by gross, light microscooc and electron microscopic levels. The results were obtained as follows. 1. Groups treated with nifedipine. α-tocopherol. nifedipine +α-tocopherol showed significant increase of the area of flap survival compared with that of the control group.(P<0.001 in nifedipine group and α-tocopherol, and P<0.01 in nifedipine plus α-tocopherol group.) 2. The flap survival was best improved in the α-tocopherol group. (P>0.05). 3. Skin including dermis after 3 days of Nifedipine plus α-tocopherol group disclosed marked proliferation and dilatations of vessels in the deeper part. 4. Electron micrograph of endothelial cells after 3 and 5 days of Nifedipine and α-tocopherol groups disclosed intact basement membrane, swelling of endoplasmic reticulum and mitochondria. Following the above results. It is suggested that calcium channel blocker and α-tocopherol seem to play a important role which incerase survival of the skin flap.

애기마름을 80% MeOH로 추출하고, 얻어진 추출물을 EtOAc, n-BuOH 및 H_(2)O로 용매 분획 하였다. EtOAc 분획으로부터 silica gel과 octadecyl silica gel(ODS) column chromatography를 반복 실시하여 2종의 화합물을 분리하였다. 각 화합물의 화학 구조는 NMR, MS 및 IR 등의 스펙트럼을 데이터를 해석하여, stigmasterol과 stigmasterol 3-O-β-D-glucopyranosyl로 구조 동정하였다. 이화합물은 애기마름에서는 처음 분리되었다. Trapa pseudoincisa was extracted with 80% aqueous MeOH, and the concentrated extract was partitioned with EtOAc, n-BuOH and H_(2)O. Two compounds were isolated from the EtOAc fraction through repeated silica gel and ODS column chromatographies. From the result of spectral data including NMR, MS, IR and GC/MS the chemical structures of the compounds were determined as stigmasterol (compound Ⅰ), and stigmasterol 3-O-β-D-glucopyranosyl (compound Ⅱ). They were isolated from Trapa pseudoincisa for the first time.

The participation in regular physical exercise can have positive effect on psycho-sociological changes as well as physiological-biochemical changes. Findings in literature concerning the special relationship between psychological wellbeing and regular physical activity have suggested that physical activity may modify state variable such as anxiety and depression. There is evidence that in addition to reducing levels of anxiety and depression. exercise can improve such psychological paramaters as self-confidence. feelings of control. self-determination. self-sufficiency. Exercise as an effective tool in promoting psychological wellbeing, positive and negative addiction to exercise are discussed. In sociological aspects. we have discussed socialization via sport. In general. sport proponents frequently claim that sport produce such desirable traits as democratic citizenship, moral character, adjusted personality. respect for constituted authority. cultivation of discipline. But at the other critics have condemned modern sport for excessive violence. overemphasis on winning. and exploitation of individuals. We have discussed in terms of these contrasting perspective. Whether traits. skills. and value learned in a specific sport context will carry over to other contexts depends upon several dimensions of social interaction.

高良坤,金明五 全北大學校 1994 論文集 Vol.37 No.-

The purpose of this paper is to disclose the effects of exchange rate volitility on the export prices of manufactured goods in Korea for the last 20 years. In addition to that, to search for appropriate policies for our exporting companies and government is also a goal. The method of this study is based on the mark-up pricing theory. The results of this study show that (1) the effect of won/dollar exchange rate volitility is strong,and then (2) the factor of foreign competition and (3) the world import follow after (1). Accordingly, these results make our export companies do their best to improve their productivity and to accept the pricing-to market strategy like Japanese companies.Also,our government must accompolish the stability of prices and improve the environment of our companies in order to get the good effect of exchange rate volitility as much as possible.

Objectives : This study aimed to examine the effect of biofeedback treatment on the clinical symptoms and stress responses in chronic headache patients. Methods : We recruited 18 chronic headache patients who were treated with 8 sessions of biofeedback treatment and 18 age and sex-matched control headache patients. All subjects consisted of patients with chronic tension headache and migraine hea-dache. Stress responses were measured using Symptoms of stress (SOS) inventory and all subjects performed Beck depression inventory (BDI), Spielberger state anxiety inventory (STAIS), and visual analogue scale (VAS). Biofeedback physiological vaiiables including frontal and forearm EMG, electrodermal response (EDR) and skin temperature at pre-and post-treatment were also measured in all subjects. Results : Compared with control patients, patients on biofeedback treatment showed significant reduction in scores of STAIS(t=3.705,P<.001),andVAS (t=3.392, p=.001) as well as SOS subscales ; peripheral manifestations (t= 1.788, P=.042), habitual pattems (t=2.008, P=.027), depression (t=2.081, P=.023), anxiety (t= 1.990, P=.028), and total score (t=2.045, p=.025). There was a significant increase of skin temperature (t= -1.835, P=.038) only in the biofeedback treatment group. Conclusion : These results suggest that biofeedback treatment may be effective in relieving chronic headache by reducing psychological and physiological stress responses.

The purpose of this study is to find out problems through ollking into the actual condition of management and the extent of application in cooking practice in High School Home Economics Education, and as a practical subject, to present some basic materials to contribute to accomplishing the object of High School Home Economics Education through trying to find a direction to enhance educational value. The contents of this study are these : to study with a theoretical background character, object, and contents of Home Economics referring to related books nad to investigate the actual condition of management, the extent of application to life of cooking practice unit, and standard of recognition of students and teachers about this subject and to find out rational nad efficient method of management. 552girl students and 72 home economics teachers in cities and counties in Kangwon-do were asked to answer the answer-wheet prepared. The result of this study is summerized as follows. 1.Most of the respondents regard the characters and objects of Home Economics as a metter of baisc education, education for life, and education for the wholeman, but they they neglect the aspect of education for a course of this subject. 2.Among the contents of Home Economics, students are much interested in the Unit of preparing table, especially in cooking. Most of the teachers teach the cooking unit only explanation without practice because of the lack of material and human resources. 3.Students have desire to do cooking practice, but the extent of application to their real life appears to be low. 4.It appears to be necessary that boy students as well as girl students should learn Home Economics as an education for preparation for managing housework. 5.Home Economics teachers are mostly satisfied which their teaching profession. But teachers who have been teaching for 3 or 5 years appear not to be satisfied with it. 6.Although Home Economics teachers can teach Cooking practice Unit with confidence, they usually do it theory rater than with practice, and they evaluate it after practicing, but most of them do not add the result to the student's grade. 7.They use most of the cookers fixed on the standard list of High School Cooking Practice appliances, but they seldom use electric heating cookers. According to the above result, we should take the following into account in order to improve probiems shown below. 1) Contents of this subject should consist of definite ones so that students can find out their aptitude and ability. 2) Video materials for efficiency of cooking practice, guide books for cooking experiment, and tools for evaluation should be developed and distributed. 3) Boy students as well as girl students should learn Home Economics together. 4) The extent of application should be enhanced by developing concrete programs of Home Profect, grade repectively so that, in addition to the scientific knowledge and function, education for how to see things and how to think should be emphasized. 6) It is required that contents should consist of meterials for settling and developing traditonal food culture. 7) Environment problems and welfare affairs of aged society as well as international affairs of the world food situation, and development and exploitation of new food resources should be dealt coherently in vocation and home economics education subjects of elementary, middle, and high school. 8) Each Home Economics teacher is required to spare time for his self-study on good condition, to be very good at contents of all spheres of practics in Home Economics, and to have confidence in teaching the subject. 9) The number of students in practice lesson should be limited to 20 to 30 in order to meet the need of the students. 10) A plan for establishing organization of school cooking practice should be discussed by regional groups. 11) A new design of cooking practice room which is available throughout the year should be made. 12) A study association of vocation and home economics should be established to provide teachers with information and opportunity of re-education, and to make and distribute teaching materials so that teachers may have leading abilities coping with internationalization and informationalization with up-to-date attitude. 13) Practical aspect of Home Economics should be emphasized, with which students are able to choose life-information and to play a chould consumer's role.

Infection is a major complication and potentially life-threatening in patients with acute leukemia. The patients require prompt broad-spectrum antibiotics therapy when fever develops. One of the keys to successful patient management is the recognition of institutional trends of the spectrum of infections and infecting microorganisms. So we evaluated 138 patients with acute leukemia and blastic crisis of chronic myelogenous leukemia admitted to Seoul National University Hospital from July 1986 to June 1992. The results are following: 1) Total number of febrile episodes was 224 and 60% of them occurred after chemotherapy. 2) Microbiologically-defined infection, clinically-defined infection, and unexplained fever accounted for 28%, 45%, 27% of the febrile episodes respectively. 3) Fifty-eight percent of microbiologically-defined infections were caused by gram-negative bactria, and 36% were gram-positive bacteria. There was a tendency to a greater proportion of gram (+) organisms than that of the last study (p>0.1). Escherichia coli was the most common organism, and coagulase-negative staphylococci, Pseudomonas aeruginosa, Klebsiella pneumoniae were common in decreasing order. 4) Pneumonia was the most common type of infection, followed by skin and soft tissue infection, perianal infection, gingivitis and primary septicemia. 5) Seventy-two percent of total infections improved with therapy and this success rate was higher than that of the last study(p<0.001).
