The dominant incidents category for onshore and offshore natural gas transmission pipelines in the world is associated with outside forces. Incidents in the outside forces category embrace acts of nature, which typically cause widespread structural damage, as well as act of man, whose effects tend to cause dents and/or gouges localized at point of contact that are referred to as mechanical damage. Therefore, these damage types must be better addressed to avoid unnecessary and costly repairs and the possibility of catastrophic events. First of all, the characterizing features of mechanical damage in gas pipelines were evaluated by using of excavator or boring machine. There is no reliable method for evaluating the safe operating pressure of pipeline affected by mechanical damage. It is especially important to evaluate the remaining strength of damaged pipelines due to outside force. Therefore, the full scale burst tests were conducted to evaluate the remaining strength of pipe with mechanical damage that combines a dent and a gouge. This paper is supposed to provide information that will assist in developing a criterion to assess serviceability in pipelines with mechanical damage.

X-ray system which is usefully used in diagnosis of the patient, being bombed of radioactivity is a big weak point when irradiates a X-ray to the human body so that ICRP restricted the radiation exposure tolerance of the human body. In order to reduce being bombed, the many research and development is now advanced. A lots of diagnostic X-ray machines have currently used due to the increase of occurrence efficiency of X-ray and precisely the output control by using the inverter which is a high speed switching semiconductors. For getting the confidence of the X-ray machine, the same radiation occurrence, same evaluation, and same irradiation condition are necessary when evaluates X-ray irradiation. It is the most important part for the accuracy of the test result and the patient safety. This research has produced the high voltage occurrence system of full-wave rectification method by using the LC resonance inverter, and evaluated the irradiation reproducibility in order to use it in diagnosis of the patient.

Medical X-ray has been brought many changes according to the rapid development of high technology. Especially, for high-voltage generator which is the most important in X-ray generation the traditional way is to use high-voltage electric transformers primarily. However, since it is large and heavy and the ripple rate of DC high-voltage applied to X-ray tube is too big, it has a disadvantage of low X-ray production efficiency. To solve these problems, the studies about high-voltage power supply are now proceeding. At present, the high-voltage generator that generates high-voltage by making high frequency using inverter control circuit consisting of semiconductor device is mainly used. High-voltage generator using inverter has advantages in the diagnosis using X-ray including high performance with short-term use, miniaturization of power supply and ripple reduction. In this study, the X-ray high-voltage device with inverter type using pulse width modulation scheme to the control of tube voltage and tube current was designed and produced. For performance evaluation of produced device, the control signal analysis, irradiation dose change and beam quality depending on the load variation of tube voltage and tube current were evaluated.

This study divided 24 healthy college students into group of aerobic exercise after resistance exercise of 8 students, the group of resistance exercise after aerobic exercise of 8 students and the control group of 8 students and thereby conducted a combined exercise program of different order for 12 weeks. This study compared and analyzed the changes of metabolic hormones. Resistance exercise was conducted four times a week with the intensity of 60 through 70% of 1RM during the 1st through 8th week and the intensity of 70 through 80% of 1RM during the 9th through 12th week. Aerobic exercise was conducted four times a week with the intensity of 60 through 70% of maximum heart rate during the 1st through 8th week and the intensity of 70 through 80% of maximum heart rate during the 9th through 12th week. The conclusions are as follows. Epinephrine were significantly higher in both the group of aerobic exercise after resistance exercise and the group of resistance exercise after aerobic exercise than the control group after 8 weeks of training and showed a similar results in the two groups. Insulin significantly decreased in the group of resistance exercise after aerobic exercise, and norepinephrine significantly increased. They were a more effective method in the results by the type of program. As a result, the exercise program to conduct aerobic exercise after resistance exercise among different types of combined exercise program was effective in relation to the degree of obesity following the purpose of execution of exercise. In the changes of metabolic hormones, the exercise program to conduct resistance exercise after aerobic exercise was more effective for lipid metabolic by decreasing insulin levels. In relation to the elements of physical fitness and energy metabolism, the two groups showed a similar effect regardless of the order execution of exercise.

The purpose of this study was to investigate the effects of long term aerobic dance training on bone mineral density in postmenopausal women. The subjects for this study were twenty postmenopausal women who participated in. this experiment voluntarily. The subjects were divided into two groups: aerobic dance training group(n=10), and nonexercising control group(n=10). The subjects in aerobic dance training performed four times a week on 60-85% HRmax. For the Lumbar2~4, Fumur neck, Ward`s triangle, Fumur trochanter were conducted before the training and after training(16 weeks), respectively. The results of this study were as follows; First, aerobic dance training group had significant increases in the Fumur neck, Fumur trochanter and increases in the Lumbar2~4, Ward`s triangle after training, whereas control group decreases. Second, ANOVA results indicated that there were significant differences between the training and control group in the amount of change in the Fumur neck, Fumur trochanter. The present results demonstrate that long term aerobic dance training have effect on the maintenance and improvement of the density of bone in postmenopausal women.

The purpose of this study was to first identify significant differences between the importance and performance of visitors to the Seorak Cultural Festival, a local cultural festival, and secondly, to suggest ways to revitalize the Seorak Cultural Festival festival program through a modified IPA comparative analysis of traditional IPA and Vavra. Frequency analysis, corresponding sample analysis, and regression analysis were used, and the results derived from the study are summarized as follows. First, there were statistically significant differences in the average value of importance and performance in the opening concert, closing concert, youth Hanmadang, regional representative cultural and artistic performances, family Olympics, receipt events, Seoraksan memory recall mission, and Seorak Cultural Festival certification tour. Second, as a result of analyzing the traditional IPA and the modified Vavra IPA, the traditional IPA included 7 in B-side (including youth Hanmadang), 8 in C-side (including fringe performance), and 3 in D-side (including fringe performance). Meanwhile, the revised IPA analysis results of Vavra, an IPA designed to improve the concentration of traditional IPA, included five I-quadrant, three II-quadrant, seven III-quadrant, and two IV-quadrant among a total of 17 attributes. Third, as a result of the revised IPA comparison analysis between traditional IPA and Vavra, five items (opening concert, street parade, civic song festival, youth culture and arts performance), and three sides, which are non-major elements, were included (Seoraksosa, Sokcho Youth Mall, receipt event, and Seorak Cultural Festival certification tour).
