조봉오, 이인녕, 정균근, 장창현. 좌업 시간과 알코올 섭취가 30대 남자 사무직 근로자의 혈압과 혈관탄성에 미치는 영향. 운동과학, 제23권 3호, 241-248, 2014. 본 연구의 목적은 일과 중 대부분을 좌업근무 형태로 업무를 수행하고, 스트레스로 인해 음주가 잦고, 운동이 부족한 30대 남자 사무직 음주자 15명을 대상으로 좌업 시간과 알코올 섭취가 혈압과 혈관탄성에 미치는 영향을 분석하여 사무직 근로자에게 건강관리에 필요한 정보를 제공하는데 있다. S대학 운동 생리학 실험실에서 사전 인적 사항과 설문을 작성하고, 신장, 체중, 채혈, 혈압, 혈관탄성, BMI를 측정하였다. 알코올 섭취 횟수, 섭취량, 좌업 시간, 그리고 음주 섭취 전과 후 및 시간대별 (10분, 40분, 60분) 혈압과 혈관탄성의 변화를 측정 분석한 결과를 요약하면 다음과 같다. 1) 평균 좌업시간이 9.87시간, 음주횟수 및 음주량은 월 평균 9.13회와 12.47잔 이였다. 2) 알코올 섭취횟수 및 섭취량에 따른 BMI, TC, LDL-C, HDL-C, 혈압과 혈관탄성 비교에서 알코올 섭취횟수에서 좌상지 혈관탄성은 통계적으로 유의한 차이를 나타냈다(p<.05). 3) 알코올 섭취 전, 후 비교 분석 결과 우상지와 좌상지의 혈관탄성에서 통계적으로 유의한 차이가 나타났다(p<.05). 4) 알코올 섭취 후 시간대별 우상지 혈관탄성은 통계적으로 유의한 차이를 나타냈다(p<.05). 이상의 결과를 종합해 볼 때, 좌업 시간이 혈압과 혈관탄성에 미치는 영향은 통계적으로 유의하게 나타나지 않았고, 알코올 섭취는 혈관탄성에 통계적으로 유의한 차이를 나타냄을 알 수 있었다. 따라서 이는 직장생활의 스트레스를 음주로 해소하는 경향이 있음을 보여주며 건강에 부정적인 영향을 주고 있음을 알 수 있었다. 또한, 신체가 음주에 적응되어 실험 시 섭취한 적은 양(1/2병)은 1회 12.47잔에 비해 혈압과 혈관탄성에 큰 영향을 미치지 못한 것으로 사료된다. Cho, Bong-Oh, Lee, In-Yeong, Jeong, Gyun-Geun, Jang, Chang-Hyun. Effects of Sedentary Occupation Time and Alcohol Intake on Blood Pressure and Vascular Compliance in 30s Male White-Collar Workers. Exercise Science, 23(3): 241-248. 2014. The purpose of this study was to examine effects of duration of sedentary office work and alcohol intake on blood pressure and vascular compliance in male subjects who were office workers aged between 30 to 39 and frequently drink alcoholic beverages to cope with their stress without exercising for health. The study was to provide health-related information necessary for white-collar workers. We collected data of demographic information, height, weight, blood sample, blood pressure, vascular compliance, and BMI from 15 subjects in S University`s Exercise Physiology Laboratory, and analyzed the frequency and amount of alcohol intake, duration of sedentary work, and changes in blood pressure and vascular compliance at diffident time points (10, 40, and 60 minutes post drinking) from baseline. I t was found that the average time of sedentary work was 9.87 hours, drinking 9.13 times a month on average, 12.47 glasses of alcohol beverages per drink. In comparison of BMI, TC, LDL-C, HDL-C, blood pressure and vascular compliance upon the frequency and amount of alcohol intake, the upper left limb`s vascular compliance had a statistically significant difference (p<.05). In the result of the comparative analysis of pre-and post-drinking, vascular compliance was significantly different in the upper right and left limbs (p<.05). Vascular compliance in the upper right limb after drinking significantly changed (p<.05). As a result, the duration of sedentary work had no statistically significant difference in blood pressure and vascular compliance. T he vascular compliance after drinking h ad a statistically significant difference. This suggested that the result was an index that shows the trend of the office workers releasing their work stress by drinking alcoholic beverages, and that drinking had negative impacts on them. In addition, a small amount of intake (a half bottle) at the test time, after the body was adjusted to drinking, compared with 12.47 glasses per intake, had no great impacts on blood pressure and vascular compliance.

A Korean translation of the original epitaph on the five-story pagoda at Gesim temple in Yecheon was done by correcting the errors of all records issued by Choseon Chong Dog Bu (Japanese Headquarter), and by footnoting. The main points of the epitaph are as follows: On March 3, 1010, King Hyeon Jong during Go Rye dynasty ordered to construct a pagoda at Gesim temple in order to set up a good stupa. At that time, about 10,000 Buddhist believers, military reserves, and farmers, as well as 1,000 cows with wagons participated in this construction. Thus, repay the Buddhist mercy to the heaven and establish righteous mind for the country, and wish to let the inculcation of Buddha spread to the rank-and-file in the earth. In the name of mother, Im Jang Bu, head of the village in Yecheon, erected the pagoda. It was erected in April, 1011.

Since the residential load is an AC load and the output of solar cell is a DC power, the photovoltaic system needs the DC/AC converter to utilize solar cell. In case of driving to interact with utility line, in order to operate at unity power factor, converter must provide the sinusoidal wave current and voltage with same phase of utility line. Since output of solar cell is greatly fluctuated by insolation, it is necessary that the operation of solar cell output in the range of the vicinity of maximum power point. In this paper, DC/AC converter is three phase PWM converter with smoothing reactor. And then, feedforward control used to obtain a superior characteristic for current control and digital PLL circuit used to detect the phase of utility line.

The purpose of this study is to analyze the current status of small-decentralized sewage treatment facilities in Chung-nam province, investigate the maintenance problems and removal efficiency of the facilities. As the analytical results on affective factors to water quality concentration, the BOD removal efficiency was 90% when the volumetric loading of aeration tank has been 0.6-0.7kgBOD/㎥·d and the nitrogen removal efficiency was about 30% at 0.5kgN/㎥·d. Therefore it is required to establish nitrogen removal process to prevent serious eutroiphication of small river. The average concentration of effluent for 12 facilities was 11.6mg/l BOD, 11.5mg/l COD, 7.7mg/l SS, 23.968mg/l T-N and 4.721mg/l T-P. Also, the removal efficiency of pollutant in order was 81.6% BOD, 72.9% COD, 77.7% SS, 33.5% T-N and 31.3% T-P. The quality of all effluent was less than discharge quality standard. But the removal efficiency of N, P was very low. Seasonal effluent water quality of each process was constant except High-efficient Sewage Treatment Package. BOD and SS concentration in Contact Oxidation process changed widely and another items such as COD, T-N and T-P was similar to all processes on hourly variation measurement. The problems of facilities were responsible management evasion of the subjects, lack of awareness by the residents to the facility, civil appeals such as electricity tax and noise and so on. So it is suggested that operator has to analyze the water quality of facilities periodically and it is necessary to support systematical, administrative measures and technical complement for responsible management.

The purpose of this study was to evaluate the analgesic effect of micro-TENS (Magicpulse) in patients with acute and chronic pain. We divided the pain of the subjects into two groups, such as acute pain(pain duration less than 3 months) and chronic pain(more than 3 months), and the analgesic effect was measured by VAS(Visual Analogue Scale) difference, VAS improvement ratio and thermographic change between pre-treatment and post-treatment. As a result, VAS difference was 4.59 ±2.75 in acute pain group and 4.00 ±1.96 in chronic pain group(p<0.01, respectively), and the patients with VAS improvement ratio(>50%) were 62.4% in acute pain group, 46.6% in chronic pain group. A significant increase in skin temperature was observed after treatment(p<0.05). We concluded that the micro-TENS has an analgesic effect on both acute and chronic pain, and the better effect is expected in acute pain than chronic pain.
