The purpose of the study was to undertaken to analysis the Grab starting technique between national representive team(3) and Cheju's representive team(3) with 3D cinematography. The conclusions obtained were as follows: Cheju's showed more elapsed time than national representive team on starting block. and more vertical than horizontal direction of COG position, more concentrated vertical velocity & acceleration than forward direction. Therefore It is necessory for cheju's to train balanced trust force in horizontal and vertical direction in grab starting technique.

Moyamoya disease is an occlusive intracranial arteriopathy with an abnormal cerebral vascular collateral networks. Although this disease is known to be associated with stenosis of extracranial arteries, such as the renal artery, a case associated with stenosis of the coronary artery is extremely rare. We report a case of coronary artery occlusive disease affected by Moyamoya disease. The patient was a 38-year-old female experiencing intermittent headache and exer tional chest pain. Cerebral MRI showed complete obstruction of both internal carotid arteries and abnormal cerebrovascular systems which confirmed Moyamoya disease. Coronary angiography showed a significant stenosis of left anterior descending coronary artery ostium with TIMI grade I collateral blood flow from the normal right coronary artery. After coronary artery stenting and medical treatment for headache, her subjective symptoms were relieved. In Moyamoya patient, an evaluation of the extracranial (especially coronary artery) vascular system should be considered if there are some evidences of coronary artery disease.

This paper aims to give an overview of the methods to inherently prevent human errors and to effectively mitigate the consequences of such errors by securing defense-in-depth during plant management through the advanced man-machine interface system (MMIS). It is needless to stress the significance of human error reduction during an accident in nuclear power plants (NPPs). Unexpected shutdowns caused by human errors not only threaten nuclear safety but also make public acceptance of nuclear power extremely lower. We have to recognize there must be the possibility of human errors occurring since humans are not essentially perfect particularly under stressful conditions. However, we have the opportunity to improve such a situation through advanced information and communication technologies on the basis of lessons learned from our experiences. As important lessons, authors explained key issues associated with automation, man-machine interface, operator support systems, and procedures. Upon this investigation, we outlined the concept and technical factors to develop advanced automation, operation and maintenance support systems, and computer-based procedures using wired/wireless technology. It should be noted that the ultimate responsibility of nuclear safety obviously belongs to humans not to machines. Therefore, safety culture including education and training, which is a kind of organizational factor, should be emphasized as well. In regard to safety culture for human error reduction, several issues that we are facing these days were described. We expect the ideas of the advanced MMIS proposed in this paper to lead in the future direction of related researches and finally supplement the safety of NPPs.

The superficial spreading type of early gastric cancer has usually been defined as an early gastric cancer in which the product of the longest diameter and the diameter perpendicular to it was greater than 25㎠. Although the superficial spreading type of early gastric cancer is histologically aggressive compared with those without such histological aggressiveness, the 5 year survival rate is as good as a non-superficial spreading types of early gastric cancers if the wide surgical resection with extensive lymph node dissection is performed as a treatment. We experienced a case of superficial spreading early gastric cancer in a 59-year-old man. This case is reported with a brief review of related literature.

제2형 당뇨병 외래 환자의 비만도에 따른 미세혈관합병증

Background: Korean type 2 diabetic patients who are frequently non-obese, may be genetically different from Western type 2 diabetics who are frequently obese. Therefore, the diabetic complications of type 2 diabetes mellitus in Korea may be also different from those of Western countries. Until now, most studies reported in Korea did not analyse the microvascular complications of type 2 diabetes mellitus according to obesity, and also the criteria in the diagnosis of microvascular complications were different in each study. We investigated the microvascular complications and its relationship with obesity, in type 2 diabetic patients visiting an outpatient clinic. Methods: The study subjects were type 2 diabetic patients visiting an outpatient clinic of Ajou University Hospital. We selected patients participating in a 75 g oral glucose tolerance test, retrospectively. Type 2 diabetes was diagnosed according to the WHO/NDDG classification of diabetes. Biochemical studies including lipid profile, plasma insulin and C-peptide levels were done. Anthropometric measurements were performed. Based on BMI (㎏/㎡), the patients were divided into the following groups: the lean group, when the BMI was less than 20 ㎏/㎡ the ideal body weight (IBW) group, if the BMI was between 20 ㎏/㎡ and 25 ㎏/㎡ in women and 20 ㎏/㎡ and 27 ㎏/㎡ in men; and the obese group, when the BMI was $gt;25 ㎏/㎡ in women and $gt;27 ㎏/㎡ in men. Results: 1. Neuropathy (45.2%) was the most frequent among the microvascular complications, and the frequency of retinopathy was 15.1%, and that of nephropathy was 4.9%. Within 5 years of diabetes duration, the frequency of neuropathy, retinopathy, and nephropathy was 43.2%, 11.8%, and 2.9%, respectively. 2. Glycosylated hemoglobin (HbA_(1c)) and fasting blood glucose levels were not different among the three groups. Beta cell function{Δ (insulin 30min - insulin Omin)/Δ(glucose 30min - glucose 0min)} was the highest in the obese group. However, beta cell function(ΔI/ΔG) divided by the basal insulin level, considered insulin resistance, was not different among the three groups. 3. Within 5 years of diabetes duration, retinopathy tended to be the most frequent in the lean group, whereas neuropathy tended to be the most frequent in the obese group, and body mass index influenced the retinopathy and neuropathy, statistically significantly. Conclusion: Diabetic neuropathy was the most frequent among microvascular complications of type 2 diabetes mellitus in our study subjects. At the time of presentation within 5 years of diabetes duration, the lean group of type 2 diabetics had a tendency of the more frequent retinopathy, the obese group had a tendency of the more frequent neuropathy. These results suggest that type 2 diabetes mellitus in Korea is also not a single disease entity, as in Western countries and is a heterogenous group of disorders with a diversity of microvascular complications. However, the more studies about this will be required.

The role of dietary fiber in health and nutrition has, since the mid 1970s, stimulated a wide range of research activities and caught the public's attention because of it's important physiological effects in human body. 1. Dietary fiber can be defind chemically as "the sum of the polysacharides and lignin which are not digested by endogenous enzymes of the human gastrointestinal tract. 2. As analytic method of dietary fiber, neutral detergent fiber (NDF) method, Southgate type method and enzymatic method are proposed. 3. Dietary fiber components can be divided two types; water-soluble and water-insoluble materials. 4. Dietary fiber has a wide of physico-chemical properties, such as water-holding capacity, adsorption of organic molecules, cation exchange reaction as well as microbial degradation. 5. Dietary fiber has also characteristic physiological effects in relieving constipation, lowering serum cholesterol, treating diverticular disease, decreasing the some ingested toxic substance, preventing various disorders such as heart disease, colon-rectal cancer, diabetes, obesity, and ulcerative colitis. 6. National Institute of Cancer(NIC) recommended a daily intake of the dietary fiber of 25-35g for healthy by adults.

To compensate phase shift caused by the electronics, the distance meter employs two optical paths, generated by splitting the laser beam into an internal fixed path and a variable distance external path. Because of the perturbations of the atmospheric index of refraction, the amplitude of the external path signal may vary greatly It is necessary to equalize the internal path amplitude with the external path amplitude to subtract the common phase shift In this study, the optical AGC circuit is developed by means of a motor-driven variable-density attenuator.
