Kojedo is the second largest island in Korea and a total population of 115,500 is living on the island of 394.69 sq. km. Under the direction of three nutrition professors, nutrition surveys in two villages in Kojedo, namely Siljun Ri in Hachung Myon and Soowol Ri in Shinhyun Myon, were carried by 30 college senior students majoring in nutrition from August to 20 August 1977. From a total of 176 households of the two villages, 67 households were randomly selected and 390 family members of the households were subjcets of the nutrition surveys. The precise weighing method was used in evaluating the kinds of foods and nutrient intakes of the subjects for three consecutive days. Thirty-seven pre-school children aged between 3 to 6 years and 27 fertile women were examined for biochemical findings and physical status. The main purposes of the surveys are to provide baseline data on nutrition in Kojedo Island for the Kojedo Community Development Project and to compare the nutritional status of the villages of Siljun Ri and Soowol Ri. Siljun Ri is located in the pilot project area of the Koiedo Community Health Project sponsored since December 1970 by the Christian Medical Commission of the World Council of Churches. While Soowol Ri is a control village for comparison. The results obtained are summarized as follows: Food Intake The average food intake per person per day in Siljun Ri, 1064 grams (91.7% in vegetable foods and 7.6% in animal foods) was 90 grams more than that of Soowol Ri, 974 grams (92.8% in vegetable foods and 5.9% in animal foods). However, the food intake per pre-school child in Siljun Ri, 485 grams (92.6% from vegetable foods and 6.4% from animal foods) was 21 grams lower than that of the Soowol Ri, 506 grams (88.5% from vegetable foods and 6.5% from animal foods). The average intake of beans was 16 grams(1.5% out of the total food intake) in Siljun Ri and 21 grams(2.2% of the total food intake)in Soowol Ri. The villagers should be guided for more consumption of soybeans to improve the quality of protein intake from vegetable foods. Nutrient Intake The adult intake in Siljun Ri and Soowol Ri were 2,529 kcal and 2,511 kcal respectively. The average energy intake of pre-school childen in Siljun Ri was 948 kcal and that for adult and 1,500 kcal for childen aged between 4 to 6 years-given by the Korea FAO Association, the diets in both villages were not adequate. Average daily protein intake of the subjected adult in Siljun Ri was 78.4 grams and that of Soowol Ri was 76.2 grams, while pre-school children took 30.7 grams in the former village and 31.7 grams in the latter village per child per day. The protein intake in both villages were lower than the recommended allowances, 80 grams for adult and 45 grams for $4{\sim}6$ years childen, and animal protein intake of the all subjects was very much lower than the RDA. The main charecter of the diet has been found low in quality of protein and high in carbohydrate. The calcium intakes of the pre-school children in both villages, 251.9 milligrams in Siljun Ri and 218.8 milligrams in Soowol Ri, were very much lower than the recommended allowance of 500 milligrams per day. It is apparent that the diet for children should be supplemented with calcium. Among the vitamin group, the daily average intakes of vitamin A and $B_{2}$(thiamine), $B_{2}$(riboflavin), C(ascorbic acid), and niacin were not adequate for the children in both villages. Especially the intake of riboflavin, 0.4 milligrams in both village children, was much lower than the RDA, 0.9 milligrams per day. Physical Characteristics Average height, weight, chest and head circumference of the pre-school children in both villages were similar to those of the Korean standard given by the Korean Paediatrics Association except that the average height of pre-school boys in Siljun Ri was 8 cm higher than the Korean standard of 105 cm. The mean values of upper arm circumference and skinfold thickness of pre-school boys in both villages were the same, 15.4 cm for upper arm circumference and 6.8 mm for skinfold thickness, but the mean values of those of the girls in Siljun Ri were higher than those of pre-school grils in Soowol Ri. Biochemical Findings Avera ge hemogobin value of boys and girls in both villages was the same, 11.1 grams per 100 ml of blood. The incidence of anemia (Hb value below 11g/100ml) was similar in both viltagesr 36.4% for boys and 50% for girls in Siljun Ri and 37.5% for boys and 50% for girls in Soowol Ri. Average hemoglobin values of fertile women were 10.7g% in Siljun Ri and 10.8% in Soowor Ri. The incidences of anemia(Hb valre brlow 12g/100ml) were 100% in Siljun Ri and 86.7% in Soowol Ri. The anemia of these subjects may be caused mainty low intake of good quality protein and iron intake from vegetable food. Recommendation In general, the nutritional status of a community health pilot village is not higher than that of control village due to the lack of nutrition improvement guldance services. Nutrition education should be delivered to the villagers as a main part of the health education artivities. The emphasis should be on building better health through bttter food habits and better food production as well as on preventing malnutrition and diseasrs. It can be an invaluable part of community developnent. Since nutrition is considered to be at least one-half of MCH care, no village or home visits should be made without careful provision for teaching and demoastrating something simple and practical on nutrition. The nurse, midwife, and village health worker should be the chief promoters of nutrition.

The radial artery as a graft for myocardial revascularization was introduced by Carpentier in the early 1970s. Mid-term results were unfortunately discoura ing, and the clinical experience with this graft was interrupted. At the end of the 1980s, these authors reproposed the same arterial conduit with more satisfying results, because of improved technique and pharmacological management of the graft. Between October 1994 and July 1995, 36 patients underwent myocardial revascularization with a radial artery graft in Seiong General Hospital. Left internal mammary artery was concomitantly used as a pedicled Vift in 34 patients. Fifteen patients (42%) had a complete arterial waft revascularization. A total of 12) distal anastomoses were performed (average 3.4 per patient), including 36 left internal mammary artery wafts (two sequential in 2 patients), and 23 saphenous vein grafts. The remaining 64 distal anastomoses were perFormed with radial artery grafts (mean 1.8 per patient). The radial arteries were anastomosed to the circumflex (n=38), diagonal (n= 18), right coronary(n=G), and left anterior descending coronary artery(n=2). The percent ge of radial artery graft anastomoses (64) to the total anastomoses(123) was 52%. The radial artery was used as a single graft in 10 patients, as a sequential graft in 25 patients, and two grafts in 1 patient. Twenty patients underwent associated procedures coronary endarterectomy (14), coronary artery patch angioplasty (4), mitral valve repair (1), and repair of ventricular septal rupture (1). One patient died of low cardiac output syndrome and the others had no perioperative myocardial infarction. There are no ischemic and functional complications in the arm or hand aftcr removal of the radial artery. Only 1 patient required reexploration of the am, for the hematoma evacuation, and 2 patients complained transient thumb dysesthesia of the side of the havested arm. This dysesthesia improved within one month. Postoperative angiovaphic controls were obtained in 11 patients(31%) postoperative 79 to 210 days (mean 126 days). The patency rate were as follows : left internal mammary artery (100%), saphcnous vein (100%), and radial artery(95%). We concluded that the radial artery is useful alternative graft, but long term clinical and angiographic studies are required to derterminc whether wider application is warranted.

The purpose of this study was to analyze the kinematic variables when Uchi-mata(inner thigh reaping throw) performing by Kumi-kata(engagement position, basic hold) types A, B(A: grasping part-behind neck lapel, B: chest lapel) in Judo with three dimensional analysis technique DLT method by videography. The subjects were four male judokas who have been training in Yong-In University(YIU), on Korean Representative level and Uchi-mata is their tokui-nage(favorite technique), the throwing form was filmed on two S-VHS 16mm video camera( 30frame/sec. Panasonic). Kinematic variables were temporal, posture, and COG. The data collection was performing by Uchi-mata. Six good trials were collected for each condition (type A, B) among over 10 trials. The mean values and the standard deviation for each variable were obtained and used as basic factors for examining characteristics of Uchi-mata by Kumi-kata types. The results of this analysis were as follows : 1) Temporal variables The total time elapsed(TE) by Uchi-mata of types A, B were 1.45, 1.56 sec. respectively. Types A shorter than B. 2) Posture variables In performing of Uchi-mata, the range of flexion in type A, left elbow was $45^{\circ}$ and B was $89^{\circ}$ from Event 2(E2) to Event 6(E6). Type A and B were quite different in right elbow angle in Event1(E1). Left shoulder angle of type A was extended and type B was flexed in E4. Both types right shoulder angles were showed similar pattern. Also both hip angles(right/left) were showed similar pattern. When type A performed Uchi-mata the knee-angle of supporting foot showed $142^{\circ}$in the 1st stage of kake phase[KP], and extended to $147^{\circ}$in the 2nd stage of KP. And the foot-ankle angle of supporting foot showed $83^{\circ}$in the 1st stage of KP, and extended to $86^{\circ}$in the 2nd stage of KP. moreover, The knee angle of attacking foot showed $126^{\circ}$in the 1st stage of KP, and extended to $132^{\circ}$in the 2nd stage of KP, and the foot-ankle angle of attacking foot showed $106^{\circ}$in the 1st stage of KP, and extended to $121^{\circ}$in the 2nd stage of KP. When type B performed Uchi-mata the knee-angle of supporting foot showed $144^{\circ}$in the 1st stage of KP, and extended to $154^{\circ}$in the 2nd stage of KP. And the foot-ankle angle of supporting foot showed $83^{\circ}$in the 1st stage of KP, and extended to $92^{\circ}$in the 2nd stage of KP. moreover, The knee angle of attacking foot showed $132^{\circ}$in the 1st stage of KP, and extended to $140^{\circ}$in the 2nd stage of KP, and the foot-ankle angle of attacking foot showed $103^{\circ}$in the 1st stage of KP, and extended to $115^{\circ}$in the 2nd stage of KP. During Uchi-mata performing, type A showed pulling pattern and type B showed lift-pulling pattern. As Kumi-kata types, it were different to upper body(elbow, shoulder angle), but mostly similar to lower body(hip, knee, ankle angle) on both types. 3) C. O. G. variables When the subjects performed Uchi-mata, COG of type A, B up and down in vertical aspect was 71cm, 73.8cm in height from the foot in the 2nd stage of KP. As Kumi-kata types, it were different on medial-lateral direction aspect but weren't different in Kuzushi phase on vertical direction aspect.

Even though there well developments in various treatment techniques for acute limb ischemia, this disease is both life threatening and limb threatening. We investigated early and mid-term results of operation for acute limb ischemia with symptoms, the combined diseases, location of occlusion, complication in our patients. Material and Method: A retrospective review was conducted in 54 patients (43 men, 11 women, mean age 67.2 years) presenting with acute limb ischemia due to arterial thrombosis or embolism between Jan. 1996 and Dec. 2003, initially underwent thromboembolectomy. Result: In 33 patients (61.1%) the timeinterval from the onset of symptom to admission was within 24 hours. Causes of acute limb ischemia were embolic occlusion (27.8%), native arterial thrombosis (66.7%), and bypass graft thrombosis (5.6%). The distribution of arterial occlusion location was at 8 aortoiliac (14.8%) and 43 distal to femoral (79.6%) and brachial (5.6%). Clinical categories were grade I in 64.8%, IIa in 24.1%, IIb in 7.4%, and III in 3.7%, All the patients were received embolectomy. Underlying diseases were heart disease (72.2%), hypertension (33.3%), cerebrovascular accident (16.7%) and diabetes (18.5%). History of smoking was noted in 96,3% of the cases. Mortality rate was 5.6％ and overall amputation rate was 9.3% (5/54). The 1-year limb salvage rate was 93.62%. Postoperative complications were 1 wound infection, 1 G1 bleeding, 3 acute renal failure, and 1 compartment syndromes. The functional outcomes of the salvaged limb according to the recommended scale for gauging changes in clinical status, revised version in 1997 were +3 in 68.5%, +2 in 9.3%, +1 in 7.4%, -1 in 5.6%, -2 in 3.7%, and -3 in 5.6%. Conclusion: This study revealed 5.6% mortality and the amputation rate was 9.3%. We have retrospectively shown good results from early diagnosis & early operation. To improve outcome, early diagnosis and understand the underlying diseases, prompt treatment and operation would be appreciated.

Introduction: The use of rabbits as a cardiopulmonary bypass(CPB) animal model is extremely dif%cult mainly due to technical problems. On the other hand, deep hypothermic circulatory arrest(CA) is used to facilitate surgical repair in a variety of cardiac diseases. Although steroids are generally known to be effective in the treatment of cerebral edema, the protective effects of steroids on the brain during CA are not conclusively established. Objectives of this study are twofold: the establishment of CPB technique in rabbits and the evaluation of preventive effect of steroid on the development of brain edema during CA. Material '||'&'||' Methods: Fifteen New Zealan white rabbits(average body weight 3.5kg) were divided into three experimental groups; control CA group(n=5), CA with Trendelenberg position group(n=5), and CA with Trendelenberg position + steroid(methylprednisolone 30 mglkg) administration group(n=5). After anesthetic induction and tracheostomy, a median sternotomy was performed. An aortic cannula(3.3mm) and a venous ncannula(14 Fr) were inserted, respectively in the ascending aorta and the right atrium. The CPB circuit consisted of a roller pump and a bubble oxygenator. Priming volume of the circuit was approximately 450m1 with 120" 150ml of blood. CPB was initiated at a flow rate of 80~85ml/kg/min, Ten min after the start of CPB, CA was established with duration of 40min at $20^{\circ}C$ of rectal temperature. After CA, CPB was restarted with 20min period of rewarming. Ten min after weaning, the animal was sacrif;cod. One-to-2g portions of the following tissues were rapidly d:ssected and water contents were examined and compared among gr ups: brain, cervical spinal cord, kidney, duodenum, lung, heart, liver, spleen, pancreas. stomach. Statistical significances were analyzed by Kruskal-Wallis nonparametric test. Results: CPB with CA was successfully performed in all cases. Flow rate of 60-100 mlfkgfmin was able to be maintained throughout CPB. During CPB, no significant metabolic acidosis was detected and aortic pressure ranged between 35-55 mmHg. After weaning from CPB, all hearts resumed normal beating spontaneously. There were no statistically significant differences in the water contents of tissues including brain among the three experimental groups. Conclusion: These results indicate (1) CPB can be reliably administered in rabbits if proper technique is used, (2) the effect of steroid on the protection of brain edema related to Trendelenburg position during CA is not established within the scope of this experiment.
