This study had a purpose to define an effect of mental strength according to the application of Taekwondo Training Programs. In order to achieve this study objective, the Delphi Technique Analysis and the Quantitative Research were carried out. For this purpose, firstly, experts' opinions about the programs which were practiced in the Taekwondo gym was analyzed. Secondly, the background variable and training level, the training programs, and the difference of Taekwondo mental strength were analyzed. And thirdly, the relations between the Taekwondo training level, the training program, and the Taekwondo mental strength, etc. were analyzed. The analysis of Taekwondo training programs by the DeIphi Technique was performed by means of the 3rd analysis with 30 experts. And as for the Quantitative Research, the study subjects were targeted for the total 265 pupils composed of 224 boys and 41 girls who were selected by the Group Random Sampling. This study took the primary school students in 4-6 years as the population who were training Taekwondo in the gym which was located in Gwangju. The measurement instrument for research survey consisted of five (5) question items for background variables, three (3) question items for training level, three (3) question items for training programs, and twenty-five (25) question items for Taekwondo mental strength, that is, which totaled thirty-six (36) question items in all. As for the relationship model settings between the related variables, gender, school year, income level, academic records, training motive variables were established. As for the independent variables, the medium variables for Taekwondo training level were set up by the training programs. And, the Taekwondo mental strength variables were established for the dependent variables. The data which were collected by using questionnaires were dealt with according to the research objectives. As for the statistical techniques for analysing the treated data, skill statistics, unitary variance analysis, multiple regression analysis were employed. As for the relation of mental strength according to the application of Taekwondo training programs based on the method and procedure of this study, the following results were obtained in accordance with the basis of the Delphi Technique Analysis and result of the Quantitative Research. First, in the program analysis through the Delphi Technique, it was investigated that the following factors were achieved. In the body-centered programs, factors such as curiosity, creative power, interest, etc. were achieved. In the mind-centered programs, factors such as social nature, character, etiquette. sense of cooperation, creative power, and interest etc. were achieved. In the play-centered programs, factors such as meditation, personal relations, creative power, self-esteem, and reliance etc. were achieved. Second, in the differences of Taekwondo programs on the basis of the background variables, school year and income level showed the statistically significant differences in the body-centered and the mind-centered programs among the types of Taekwondo training programs. And the statistically significant difference was shown about the income level in the play-centered programs. This result showed the fact that, in training Taekwondo, pupils showed differences for adapting themselves to the contents of body-, mind-, and play-centered programs according to the contents of programs based on school year and income level which were parts of the background variables. Third, in the relations between the Taekwondo training level and the programs, for the great influence which they had on the body-centered programs about the period, frequency, and the intensity. pupils could adapt themselves well to the training as the period became longer in the body-centered programs. They could also adapt themselves well to the high-intensity training when they were not absent and trained more frequently. As for the period, about the thing which it influenced the mind-centered programs, as they were trained longer in the mind-centered programs, the training period became longer. Also, as for the period and frequency. it was considered that what influenced the play-centered programs was the fact that, as pupils were trained longer, the training period became longer in the play-centered programs. And they seemed to feel more pleasure and interest as the training period became longer and when they were not absent, and when they were trained more frequently. Fourth in the relation between the Taekwondo training level and the mental strength, for the period and the frequency which belongs to the training level, the thing which had significant impact on the sub-factors of the mental strength such as patience, courage, and etiquette was the fact that patience, courage and etiquette which were the sub-factors of mental strength were improved as the Taekwondo training period was longer, and they were trained more frequently. Fifth, in the relation between the type of Taekwondo program and the mental strength, patience, courage, and etiquette was highly improved in the body-centered programs. And courage was highly improved in the mind-centered programs. Also, what had significant impact on patience, courage and etiquette was the body of the Taekwondo program type in the play-centered programs. Likewise, for the mind- and play-centered programs, the mental strength such as patience, courage and etiquette was highly improved as they were trained more frequently.

For mobile robot, the navigation effectiveness can be improved by providing autonomy, but this autonomy requires the mobile robot to detect unknown obstacles and avoid collisions while moving it toward the target. This paper presents an effective method for autonomous navigation of the mobile robot in structured environments. This method uses ultrasonic sensor array to detect obstacles and utilizes force relationship between the obstacles and target for avoiding collisions. Accuracy of sensory data produced by ultrasonic sensors is improved by employing error eliminating rapid ultrasonic firing (EERUF) technique. Navigation algorithm controlling both the velocity and steering simultaneously is developed, implemented to the mobile robot and tested on the floor filled with the cluttered obstacles. It is verified that from the results of the field tests the mobile robot can move at a maximum speed of 0.66 m/sec without any collisions.

전보에 이어 어육을 원료로 하여 보다 품질이 우수한 고온가열처리 식품을 개발하기 위한 기초 자료를 얻을 목적으로, 시료 어육을 121.1℃에서 Fo값을 5, 10, 20으로 달리하여 가열처리 했을 때 지질성분의 변화에 미치는 영향에 대하여 비교, 검토하였다. 시료 가다랑어육 및 명태육의 TBA값과 과산화물값은 가열처리에 따라 현저히 감소하였고, 감소폭은 가다랑어육 쪽이 컸다. 카르보닐값은 가열처리 중 가다랑어육은 감소하는 반면, 명태육은 증가하였다. 색조는 양 시료 모두 가열처리 정도가 커질수록 육색이 진해졌으며, 특히 가다랑어육에서 갈변진행이 현저하였다. 지질성분은 가다랑어육에는 NL의 함량이 많았고, 명태는 PL의 함량이 많았다. 98℃의 열처리에서는 양 시료 모두 NL과 PL의 조성비에 변화가 거의 없었으나, 121.1℃ 열처리에서는 Fo값 증가할수록 NL의 조성비는 높아지고 PL의 조성비는 낮아지는 경향을 나타내었다. TL, NL 및 PL의 지방 산조성은 98℃ 열처리에서는 양 시료 모두 조성비의 변화가 거의 없었으나, 121.1℃ 열처리에서는 Fo값이 증가할수록 폴리엔산의 조성비가 점차 감소했으며,특히 22:6의 감소폭이 컸다. 반면,포화산 및 모노엔산의 조성비는 증가하였다. 지방산 조성의 변화폭은 명태육 쪽이 가다랑어육에 비해 다소 컸다. Fo 20의 열처리에서 TL의 고도불포화지방산의 잔존율은 생시료에 비해 가다랑어육이 73%, 명태육이 65%였다. In present paper, we investigated the changes in lipid components of skipjack and Alaska pollack meat by thermal processing at high temperature. TBA values and peroxide values of both fish meats decreased markedly by heat treatment: decreasing range of TBA and peroxide values in skipjack meat was larger than those of Alaska pollack meat. Also carbonyl value of skipjack meat was decreased by thermal processing, contrary, that of Alaska pollack meat was increased. Total lipid(TL) of skipjack and Alaska pollack meat consisted of 61.9% , 49.6% non-polar lipid(NL), 38.1% , 50.4% polar lipid(PL), respectively. When the samples were heated at the Fo values of 5 or higher, contents of NL were increased, while that of PL were decreased. In fatty acid composition of NL and PL in both fishes, NL revealed higher contents in saturates and monoenes such as 16:0, 18:1, while PL showed higher contents in polyenes such as 20:5, 22:6; percentages of polyenes such as 22:6 especial1y in both fishes decreased with increasing of Fo values. The remaining ratio of PUFA(20:5+22:6/16:0) of Fo 20 samples in skipjack and Alaska pollack meat were 73% and 65% , respectively. However, when the samples were heated at 98℃ for 30 minutes, no appreciable changes occured in fatty acid composition of TL, NL and PL in both fish meats examined.

The processing conditions and quality of sardine surimi were examined: Raw sardine meat was separated, washed in 0.2% NaHC0_3 and 0.15% NaCl solution, and then dewatered by centrifuge. The dewatered sardine meat was chopped, mixed with 20% emulsion curd (soybean protein : water : refined sardine oil= 1 : 5. 2.6), 4% sorbitol, 4% sucrose, 0.2% polyphosphate and 0.1% sodium erythorbate by stone mortar. The mixed sardine meat was frozen with contact freezer, packed in carton box and then stored at -25±2℃. The moisture, crude protein and lipid contents of the sardine surimi product was 73.3%, 15.0% and 6.9%, respectively. Fatty acid composition of product consisted of 28.8% of saturates, 24.3% of monoenes and 47.7% of polyenes and the major fatty acids were 16:0, 20 5, 18:1, 22:6 and 16:1. The results of changes in POV, TBA value, fatty acids, texture and sensory score of products during frozen storage showed that lipid oxidation and freeze denaturation of product could be retarded, and flavor enhanced by addition 20% emulsion curd and 0.1% sodium erythorbate. In an attempt to apply sardine surimi in producing surimi-based product, it was concluded that Pollack surimi could be substituted with sardine surimi up to 40% without showing any significant changes in texture and taste of surimi-based product.

Obesity which is defined as accumulation of excess body fat, is central factor of insulin resistance syndrome. Recently, it is revealed tat adipose tissue is not simply an energy storage organ but it also secretes a variety of molecules which affect the metabolism of the whole body, those are leptin and plasminogen activator inhibitor-1(PAI-1). Therefore, leptin and PAI-1 are increased in the obese state. Leptin regulates energy homeostasis and satiety and PAI-1 regulates fibrinolytic system. For these reasons, elevated levels of leptin and PAI-1 are considered as link factors between obesity and insulin resistance syndrome. However, the exact regulating mechanism for serum levels of leptin and PAI-1 is not fully understood yet. In this study, to evaluate the regulating mechanisms of serum levels of leptin and PAI-1 according to the weight changes, we measured leptin, PAI-1, physical, metabolic, and endocrine parameters during 10 days of weight reduction and 10 days of regain period in 7 young athletes. The mean body weight change was -4.7 kg(5.0%) in the weight reduction period and -2.4 kg(2.5%) in the weight regain period compared to baseline value. Baseline level of leptin in athletes was 1.7±0.66 ng/ml, which was significantly correlated with body weight, BMI, percent body fat, body fat mass, triglyceride, insulin, and PAI-1. Baseline level of PAI-1 in athletes was 16.6±5.26 ng/ml, which was significantly correlated with body weight, BMI, triglyceride, insulin, and leptin. Leptin was decreased to 0.7±0.39(44% of the basaline value) in the weight reduction period, and increased to 1.9±0.64(119% of the baseline value) in the regain period. PAI-1 was decreased to 7.4±2.72(44% of the basaline value) in the weight reduction period, and increased to 22.8±7.33(138% of the baseline value) in the regain period. The changes of leptin during weight reduction period were significantly correlated with the changes of insulin(r=0.890, P<0.01) and triglycerides(r=0.874, P<0.01). The changes of PAI-1 during weight reduction period were significantly correlated with the changes of FFA(r=0.889, P<0.01) and triglycerides(r=0.869, P<0.05). The changes of both leptin and AAI-1 during weight regain period were significantly correlated with the changes of insulin(r=0.755 and 0.849, P<0.05, respectively). In summary, these results suggest that serum levels of leptin and PAI-1 were affected by weight cycling, the percentages of change were more greater than that of weight change, and rebound phenomena were occurred during weight regain period.

Building integrated photovoltaic(BiPV)systems can from a cohesive design, construction, and energy solution for the built environment. The benefits of building integration are well documented and are gaining significant public recognition and government support. PV cells, however, convert only a small portion of the incoming isolation in to electricity. The rest is either reflected or lost in the form of sensible heat and light. In order to judge of the Integration capability to the BIPV system, energy efficiency, capacity and integration capability is studied by considering the production quantity of electric power and U-value of PV system.

Since the development of magnetic stimulation as a way of assessing the function of central motor pathways, various neurologic diseases have been investigated by motor evoked potentials(MEP). This study was carried out to evaluate the usefulness of clinical application of MEP to the stroke patients. MEP were elicited with transcranial cortical stimulation using a magnetic coil in 21 healthy subjects and 18 stroke patients. Average of age was 37.5±18.0 and 63.7±7.7 years in normal and patient groups respectively. All stroke patients had a mild to severe clinical unilateral motor weakness, and also were proven to have unilateral infarction or hemorrhage at various regions of brain radiologically. During MEP studies, neither significant side effects nor pin were encountered. MEP latency of abductor pollicis brevis(APB) and extensor digitorum brevis(EDB) in controls measured 22.4±2.0 msec and 41.8±2.9 msec respectively. Normal central motor conduction time(CMCT) was 9.7±1.6 msec and 19.3±2.3 msec respectively. The amplitudes of MEP were not reliable due to great variability. Abnormal responses were noted in 5 patients on the APB and in 12 patients on the EDB motor evoked potentieal studies. Mean latency and CMCT were significantly prolonged in involved sites of the other 16 patients, comparing with control data. Prolonged latency and CMCT, increased inter-side difference of CMCT. Any potential was not a useful indicator in determining abnormality of MEP study. More paralyzed patients were apt to show abnormal responses in MEP studies. There were also more abnormal results during acute stage compared with chronic stage More abnormal results were observed in the patients with cerebral cortex or corona radiata involvements. It is suggested that MEP study is a useful and sensitive method in the evaluation of stroke patients and be a effective method for further understanding of central motor system.
