본 연구는 제주지역에서 소비되는 식품류 중의 $^{137}Cs$ 과$^{40}K$ 방사능 농도를 조사하여, 식품 섭취에 따른 $^{137}Cs$와 $^{40}K$에 의한 내부피폭 선량의 값을 평가함으로써 만일의 원자력 사고로 인한 방사능 오염에 대처할 수 있는 기초 자료를 확보하고자 수행하였다. 시료로 채취한 식품류는 농산물 31, 축산물 6, 수산물 12, 임산물 4 그리고 가공식품(차류)이 3종류였고, 방사능 분석은 고순도 게르마늄검출기가 장착된 감마선분광계로 수행하였다. 시료 중 $^{137}Cs$ 방사능 농도범위는 농산물이 MDA이하 ${\sim}650\;mBq/kg$ fresh 축산물 MDA이하 ${\sim}131\;mBq/kg$ fresh, 임산물 MDA이하 ${\sim}834\;mBq/kg$ fresh, 수산물 MDA이하 ${\sim}253\;mBq/kg$ fresh, 그리고 가공식품은 $32.0{\sim}483\;mBq/kg$ fresh 이었다. $^{40}K$의 경우는 농산물 $16.6{\sim}542\;Bq/kg$ fresh, 축산물 $39.1{\sim}294\;Bq/kg$ fresh, 임산물 $85.5{\sim}116\;Bq/kg$ fresh 수산물 $50.1{\sim}657\;Bq/kg$ fresh 그리고 가공식품$33.6{\sim}1,065Bq/kg$ fresh 범위였다. 시료 중 $^{137}Cs$ 방사능 농도가 가장 높은 것은 표고버섯으로 834 mBq/kg fresh 이었으며, $^{40}K$은 커피가 1,065 Bq/kg fresh로 가장 높았다. 각 식품류 중 $^{137}Cs$와 $^{40}K$에 의한 연간 유효선량은 농산물이 66,543 nSv로 가장 높았고, 축산물 19,311, 가공식품(차류) 6,648, 수산물 6,579 그리고 임산물 860 nSv 순으로 낮았으며, 이것을 모두 합한 총 연간 유효선량 값은 99,941 nSv 이었다. 본 연구에 포함된 식품의 1인당 연간 섭취량이 연간 총 식품 섭취량의 60%임을 감안해도 자연환경 중에서 이루어지는 외부피폭에 의한 연간 유효선량인 2,400,000 nSv에 비하면 무시 할 정도여서 평상시 식품섭취에 의한 방사선 내부피폭은 매우 미량이었다. 이상의 자료는 유사시 방사선에 의한 식품류 오염정도를 식별하는데 필수 불가결할 것으로 사료된다. This work was conducted to provide the reference data of radioactivity in the foodstuffs at a radiological emergency situation in Jeju Island The sampled foodstuffs were agricultural (31), livestock (6), marine (12) and forest products (4), and processed foods (3) consumed by Jeju Islanders. $^{137}Cs$ and $^{40}K$ activities were determined by HPGe r-ray spectromety. The activity ranges of $^{137}Cs$ was <MDA (less than mini mum detectable activity) ${\sim}650\;mBq/kg$ fresh in the agricultural products, <MDA${\sim}131\;mBq/kg$. fresh in the livestock, <MDA${\sim}834\;mBq/kg$ fresh in the forest, <MDA${\sim}253\;mBq/kg$ fresh in the marine and $32.0{\sim}483\;mBq/kg$. fresh in the processed foods (tea). In case of $^{40}K$ the activity was $16.6{\sim}542\;Bq/kg$. fresh in the agricultural products, $39.1{\sim}294\;Bq/kg$ fresh in the livestock, $85.5{\sim}116\;Bq/kg$ fresh in the forest, $50.1{\sim}657\;Bq/kg$ fresh in the marine, and $33.6{\sim}1,065\;Bq/kg$ fresh in the processed foods (tea). The highest activity of $^{137}Cs$, 834mBq/kg fresh was observed in oak mushroom and $^{40}K$ 1,065 Bq/kg fresh in coffee. Annual effective doses of $^{137}Cs$ and $^{40}K$ by intake of foodstuffs per capita were the following order; agricultural products (66,543 nSv) > livestock products (19,311 nSv) > processed foods (6,648 nSv) > marine products (6,579 nSv) > forest products (860 nSv). Therefore, total annual effective dose was summed 99,941 nSv which is quite low level comparing to the annual effective dose by external exposure, 2,400,000 nSv. The data obtained in this study can be useful for monitoring whether the foodstuffs are contaminated or not at an emergency radiation accident, and showed that the foodstuffs consumed in Jeju are safe in terms of annual effective dose of $^{137}Cs$ and $^{40}K$

Purpose: This study investigated the effects of progressive resistance task-oriented strengthening exercises (PRTSE) on the strength of the lower extremities, balance, and activities of daily living (ADL) of patients following a stroke. The purpose of the study was to provide fundamental data regarding the use of PRTSE with stroke patients. Methods: Twenty stroke patients were randomly divided into an experimental group (n = 10) who took part in PRTSE and a control group (n = 10) who performed general rehabilitation exercises. Both groups performed their respective exercises for 30 minutes five times a week for four weeks. The strength of their lower extremities was measured using a hand-held dynamometer. The balance of the participants was assessed using a Berg balance scale. The modified Barthel index was conducted to measure ADL. A paired t-test was performed to compare within-group changes before and after the PRTSE. Differences between the experimental and the control groups were analyzed using an independent t-test. For all tests, the level of statistical significance was α = 0.05. Results: After the exercises, there was a significant within-group change in the strength of lower extremities, balance, and ADL in the experimental group and the control group (p < 0.05). There was also a significant between-group difference in the strength of lower extremities after the intervention (p < 0.05). Conclusion: General rehabilitation is commonly applied as a treatment for stroke patients and is relatively effective. The application of PRTSE may be useful in such patients, considering its effects on the strength of lower extremities, balance, and ADL.

Purpose: The purpose of this study is to examine the effects of proprioceptive neuromuscular facilitation (PNF) exercises on the neck disability index and deep neck flexor endurance of acute whiplash injury patients and to provide basic data for PNF exercises for musculoskeletal system disorder patients. Methods: Twenty acute whiplash injury patients were randomly assigned to an experimental group (n=10) and were treated with PNF exercises whereas a control group (n=10) underwent general exercises. Each session lasted 15 minutes and was performed five times a week for two weeks. The degree of pain was assessed using a visual analogue scale (VAS) and the degree of neck disability was measured by the neck disability index (NDI). Craniocervical flexor endurance (CCFE) tests were conducted to measure deep neck flexor endurance. Results: In terms of the intragroup changes in VAS, NDI, and CCFE, there were significant decreases in both the experimental and the control groups. After intervention, there were significant differences between the experimental group and the control group in terms of intergroup changes in VAS, NDI and CCFE. Conclusion: Although the exercises that are generally applied to acute whiplash injury patients are effective on the whole, PNF exercises are considered to be beneficial, given the improvements in the neck disability index and deep neck flexor endurance.

Purpose: The study aimed to determine the effect of the proprioceptive neuromuscular facilitation (PNF) lower trapezius muscle strengthening exercise on pain, shoulder range of motion, and shoulder pain and disability index (SPADI) in patients with frozen shoulder. Methods: Following baseline measurements, 30 subjects (n=30) with frozen shoulder were randomized into two groups: the PNF group (n=15), which received PNF strength training of the lower trapezius muscles, and the control group (n=15), which received gentle palpation of the skin. Each group participated in the intervention for 30 minutes, three times per week, for six weeks. The visual analogue scales for pain, range of motion, and SPADI of both groups were recorded at both pre- and post-intervention. Paired t-tests were used to determine significant changes in the post-intervention period compared with pre-intervention, and independent t-tests were used to analyze differences in the dependent variables between the two groups. Results: After the six-week intervention, both groups experienced significantly decreased pain and SPADI (p < 0.05) and significantly increased shoulder flexion, abduction, internal rotation, and external rotation range of motion (p < 0.05). The PNF group that received the PNF strength exercise of the lower trapezius muscles showed greater improvements in pain and range of motion than those of the control group (p < 0.05). Conclusion: These results suggest that the PNF lower trapezius strengthening exercise reduces shoulder pain and disability levels and enhances shoulder range of motion in patients with frozen shoulder.

강태우(Tae-Woo Kang),박정열(Jeong-Yeol Park),이재성(Jae-Sung Lee),김명현(Myung-Hyun Kim) 대한용접·접합학회 2018 대한용접·접합학회지 Vol.36 No.5

In general, fatigue tests are conducted with a constant amplitude load to estimate the fatigue crack growth characteristics. However, vessels have variable amplitude loads because various forces are applied to them. So it is essential to consider variable amplitude loads and a constant amplitude load together. The existing data shows that fatigue crack propagation is retarded when the single or multiple tensile overloads are applied and they affect fatigue life. But there are no results of overload effect on weld metal (WM) and heat effect zone (HAZ) about Al 5083-O. This study investigates the fatigue crack growth rate characteristics of welded Al 5083-O considering the overload effects. The specimen of WM and HAZ are fabricated according to ASTM E647 and E8. Based on the results, it be successfully the fatigue retardation by the overload is investigated based on the Wheeler Model, and the fatigue life of structure can be successfully predicted from the test results.

강태우 ( Kang Tae-woo ) 경기대학교 관광종합연구소 2019 여가관광연구 Vol.32 No.-

본 연구는 여수시에 거주 중인 주민들을 대상으로 하여 문화적 정향과 주관적 안녕감에 따라 지방정부신뢰 및 관광개발 지지도에 차이가 있는지를 검증하였다. 2019년 9월 16일부터 9월 25일까지 주말을 제외한 8일 간 지역주민을 대상으로 하여 설문조사를 실시하였으며, 설문지 400부를 배포하여, 유효표본 357부를 획득하였다. 설문 결과를 바탕으로 각 문항별 탐색적 요인분석을 실시하여 문항 적합도를 검증하였으며, 이 중 문화적 정향의 문항 1개를 제외한 나머지 문항들을 본 연구를 위한 분석에 사용하였다. 문화적 정향과 주관적 안녕감에 따라 지방정부신뢰 및 관광개발 지지 차이검증을 실시하고자 일원배치 분산분석(ANOVA)를 실시하였다. 그 결과, 주관적 안녕감 문항 중 ‘내 삶에 대하여 만족함’의 경우를 제외하고 각 문항별 응답에 따라 지방정부신뢰 및 관광개발 지지에 있어 차이가 있음이 검증되었다. 즉, 개인이 가지고 있는 문화적 정향이 보수적일수록, 주관적 안녕감이 높을수록 지방정부신뢰 인식수준과 관광개발에 대한 지지도가 높음을 본 연구를 통해 확인 할 수 있다. This paper was conducted on residents living in Yeosu City to see if there are differences of local government trust and support for tourism development according to cultural orientation and subjective well-being. From September 16 to September 25, 2019, the survey was conducted on local residents for eight days, excluding weekends, and 400 copies of the questionnaire were distributed to obtain 357 effective samples. Based on the results of the survey, exploratory factors analysis for each question were conducted to verify the suitability of the questions, and the remaining questions were used for the analysis for this study, except one for the one for cultural orientation. ANOVA was conducted to verify differences of trust in local government and support for tourism development according to cultural orientation and subjective well-being. As a result, it has been verified that there are differences of trust in local government and support for tourism development depending on the responses of each question, except in the case of 'satisfaction with my life' among the subjective well-being questions. In other words, the more conservative the individual's cultural orientation and the higher the subjective sense of well-being is the higher the level of local government confidence awareness and support for tourism development.

PURPOSE: This study aimed to identify the effect of a backward walking exercise using a mirror on balance and gait in patients with stroke. METHODS: Twenty subjects with post-stroke hemiparesis volunteered to participate in this study. The experimental and control groups performed backward walking exercise plus conventional therapy or conventional physical therapy, respectively, for 6 weeks. Assessment instruments included the Berg Balance Scale (BBS), timed up and go test (TUG), and 10-m walking test (10MWT). Evaluation was performed before and after the 6-week training period. We conducted a paired t-test to compare the within-group changes before and after the intervention. An independent t-test was used to compare between-group differences. The statistical significance level was set at α=.05 for all variables. RESULTS: The experimental group showed a significant within-group change in the BBS, TUG, and 10MWT (p<.05). The control group also showed a significant change (p<.05). A significant difference was observed between the experimental and control groups with regard to changes in the BBS, TUG, and 10MWT results after the interventions (p<.05). CONCLUSION: This study demonstrated that backward walking exercise using a mirror may be valuable for future research. Further studies with a wider range of pathology and longer experiment duration are required to validate the results of the present study.
