The purpose of this study was to investigate the treatment effect of three interventions on the disuse atrophy of rat hindlimb after two weeks suspension. Forty-eight 11∼12 weeks old female Sprague-Dawley white rats were divided into four intervention groups: 1) suspension only (S; n=10), 2) intensive weight bearing treadmill (IWBT; n=10), 3) electrical stimulation (ES; n=9), 4) 2)+3) (ES/IWBT; n=9). Another 10 rats received no intervention or hindlimb suspension and served as controls (C). After the interventions, 1) the cross-sectional area (CSA), 2) the ration of white muscle fiber composition (WMFC), 3) isometric tetanic tension (ITT), and 4) muscle weights (MWs) were measured from the four calf muscle specimens. The results were as follows: 1. In all intervention groups, the CSAs of medial and lateral gastrocemius (MG•LG), soleus(SOL), and flexor digitorum superficialis (FDS) decreased when compared to the control (C) group (p<.05). The CSA increased in FDS and LG for the IWBF group, in SOL for the ES/IWBF group compared to the S only group (p<.05). 2, The rations of WMFC in MG, LG, SOL, and FDS in creased compared to the C group for all interventions (p<.05). The ratios of WMFC decreased in SOL and LG for the IWBT group, in SOL for the ES/IWBT group compared to the S only group, and decreased in SOL for the ES/IWBT group compared to the IWBT group(p<.05). 3. The ITT in the MG, LG, SOL, and FDS decreased compared to the C group for all interventions(p<.05). The ITT increased in MG•LG/FDS, SOL, and the whole calf muscles(WCMs) in the IWBT, ES and ES/IWBF groups compared to the S only group(p<.05). 4. The WMs in MG•LG/FDS, SOL, WCMs decreased compared to the C group for all interventions(p<.05). The MWs increased in MG•LG/FDS and WCMs for the IWBF group, in SOL for the ES group, and in SOL for the ES/IWBF group compared to the S only group(p<.05). 5. In atrophied muscles, the IWBT group showed the best recovery and the ES/IWBT and ES groups followed in decreasing order. The most susceptible muscle to disuse atrophy was the SOL. But conversely, it showed the best recovery in the ES/IWBT group. After two weeks of hindlimb suspension, the calf muscles of rats atrophied and their isometric tension decreased. These changes were best reversed by hindlimb-focused treadmill activity. The next best results were achieved by electrical stimulation combined with the tread mill followed by only electrical stimulation. These findings indicate that full weight bearing treadmill activity alone or in combination with electrical stimulation are effective treatments for non-weight bearing induced muscle atrophy. Further study of the effect of different intensities of electrical stimulation and variations in the duration period of full weight bearing treadmill activity on disuse atrophy is recommended.

본 연구는 LNG 저장 탱크 운반선 9% NI Steel에 대한 실험분석과 메타분석 연구이다. 본 연구는 LNG 저장 탱크운반선 9% NI Steel에 대한 선행연구에 기초해서 메타분석을 수행한 후에, 9% Ni Steel의 패스(pass)와 다층용접(multi pass)이 인장강도(tensile strength)에 미치는 영향을 분석하기 위하여 충격반응검정(impulse-response test)을 통한 실험분석을 수행하였다. 본 연구의 실험분석 결과 다음과 같은 연구결과를 얻었다, 첫째, 9% Ni Steel의 다층용접(multi pass welding)에 대한 인장강도(tensile strength)를 시험한 결과 패스 1부터 패스 3까지 인장강도가 증가하였으나, 패스 3 이후부터 다층용접의 인장강도는 감소하는 것으로 보인다. 둘째, 다층용접(Multi pass welding)이 인장강도(tensile strength)에 미치는 영향을 분석한 결과, 패스(pass), 다층용접(multi pass)이 인장강도(tensile strength) 에 유의한 정(+)의 영향을 미치는 것으로 보인다. 용접시간(welding time)이 인장강도(tensile strength)에 미치는 영향을 분석한 결과, 용접시간(welding time), 인장강도시간(tensile time)이 인장강도(tensile strength) 에 유의한 정(+)의 영향을 미치는 것으로 보인다. Laboratory and meta-analyses were done for 9% NI Steel for use in a liquefied natural gas carrier. The meta-analysis is based on a previous study. The laboratory analysis examines the effects of a single pass and multiple passes on the tensile strength through an impulse-response test. The tensile strength increased from pass one to pass three and decreased from pass four to pass ten. The pass and multi-pass welding had a positive effect on the tensile strength. Lastly, the welding and tensile time had a positive effect on the tensile strength.

This study randomly chose 10 humanity high schools, which are located in Busan and KyoungNam province. We then examined the recognition rate of physical therapy among 378 teachers who were and still are working in the schools. 1. The recognition grade of physical therapeutics between men and women was significantly different with results of 80.7% of men and 69.7% of women(p<0.05). In the case of experiencing physical therapy, 83.6% of people said they knew the physical therapeutics and in the case of the opposite side, the result was also significantly different with a result of 67.8%(p<0.05). 2. We ranked the people on how much they knew about the physical therapeutics among men and women. With men, the actual experience of physical therapeutic came before what they heard from other people. In the case of women, what they heard from other people came first and the actual experience of physical therapeutic came after. According to the public information from Inje University, the recognition grade is recorded in the 3rd grade department as 21.5% while in the case of experiencing treatment from a physical therapist, the result was 39.1%. In the other department (the 1st grade department), what men and women heard from mass media was recorded at 17.5% and what they heard from other people, it was recorded at 33.8%(p<0.05). 3. The research about the recognition of academic ability of being a physical therapist was that 55.6% of teachers thought that 3-year-college was the best, which made the results different from the recognition grade of the experience of education(p<0.05). 4. In the recognition grade of physical therapeutics, there were significantly differences from 50.2% of men and 45.2% of women were expecting about 1mil ion won to 1.99million won. In case of 25.2% of people who have experience less than 15years at work, they expected about 2million to 2.99million won. The figures were higher than 10.1% of people who have experiences over 15years. About the recognition grade of physical therapists social level in the future is 48.8% of people who had experienced of physical therapy and 63.8% of people who never had experienced of it said it would be better in the future. From these results, the recognition about physical therapeutics and the view of its social status are optimistic and they know well about the level of academic ability of physical therapists. On the other hand, most teachers don't know exactly about physical therapists work. So we have to inform them aggressively for enhancing the recognition of physical therapy because high school students are well affected by their teachers when they face their future or major in university.

The data were analyzed frequency, percentage, t-test, and one-way ANOVA using the SPSS/PC Ver. 10.0 (${\alpha}=0.05$). The results were as follows; 1. The mean score for the level of points interpersonal relations was 41.06 points in full 80 points. Therefore most students had a little problem on interpersonal relations. 2. More difficulties of interpersonal relations were felt by students in the following order; clinical instructors, patients, other students, and other department staffs in the hospital. 3. Between students and clinical physical therapist in the hospital, most students were satisfied with a instructor's attitude toward there (61.1%). 4. Between students and other department staffs in the hospital, most students were felt convenient when faced with other staffs(61.8%). 5. Between students and patients in the hospital, most students didn't uncomfortable when they made a rapport(69.2%). 6. Between students and other college students, most students were didn't inconvenient when they were practicing together(69.8%). 7. The students with higher marks in major felt more difficulties for forming personal relations with other department staffs in hospital, patient, and other students(p<0.05). 8. The students showed more felt inconveniences over 8 weeks practicing than below 7 weeks itperiods of clinical practice(p<0.05). 9. The number of practice place were significantly difference according to relation of patients, other college students(p<0.05). More less practice place were made difficult of interpersonal relations. The further studies would be made in viewpoints to clinical instructors, patients, students, others department staffs in the hospital so that we could compare our results with theirs.
