박종혁 瑞逸專門大學 1993 論文集 Vol.11 No.-

The construction equipment, recently, is substituted for man-power in construction, and it becomes one of major parts in construction site. The construction economy may not be discussed without the considerations of the rational management of the construction equipment. Therefore, the construction economy may be directly related to the enhancement of the construction efficiency. in present study, we review the basic conditions for the enhancement of the construction efficiency and provide preliminary data for the rational management of the construction equipment.

박종혁,유상권,김영명,김동수,김상무,Park, J.H.,You, S.G.,Kim, Y.M.,Kim, D.S.,Kim, S.M. 한국식품영양과학회 2006 한국식품영양과학회지 Vol.35 No.5

본 연구는 멸치액젓의 풍미를 유지시키면서, 발효 속도를 향상시키기 위하여 숙성된 멸치액젓에서 단백분해능이 뛰어난 미생물이 생산하는 효소를 분리 정제한 다음 숙성초기의 멸치액젓에 첨가하여, 멸치액젓의 품질특성을 분석하였으며 그 결과는 다음과 같다. pH는 B. subtilis JM3 단백분해효소 첨가량 및 가수분해시간에 따른 변화는 없었고, 젖산량은 4% 단백분해효소 첨가구가 제일 높았다. 아미노질소, 휘발성염기질소 및 가수분해도는 단백분해효소 첨가구가 대조구에 비해 높았으며, 갈변도는 4% 효소첨가구에서 높게 측정되었다. 가수분해가 가장 높게 나타난 2시간째에 관능검사를 실시한 결과 단백분해효소 첨가구가 향 및 맛에서 좋은 평가를 얻었다. B. subtilis JM3 pretense from naturally fermented anchovy sauce was purified in $40{\sim}60%$ ammonium sulfate fraction. In order to accelerate the fermentation of anchovy sauce,2% and 4% of crude B. subtilis JM3 protease were added to 6 month-fermented anchovy sauces, respectively and then the various quality characteristics such as pH, lactic acid, amino-nitrogen, VBN, browning and hydrolysis degree, VBN, and sensory evaluation were analyzed at different storage times. pH was constant during storage time in all samples, whereas lactic acid contents of anchovy sauces hydrolyzed by 2% and 4% proteases were higher than that of control. The amino-nitrogen and volatile basic nitrogen contents of anchovy sauce with 2% and 4% proteases were twice higher than those of control. Anchovy sauces with 2% and 4% pretense increased the hydrolysis rate by 27% and 32%, respectively. Browning degree of anchovy sauce with 4% was higher than those of 2% and control. Anchovy sauce with 2% and 4% proteases was good in sensory evaluation of color, aroma, and taste attributes.

Objectives: The purpose of the study was to identify a gap between consumer characteristics and utilization of health information on the Internet. Methods: A telephone survey of nationally representative samples was conducted using structured questionnaires, and 1,000 of the 1,189 responses obtained were included in our analysis. The following variables were included in the analysis as potential predictors of health information use on the Internet: predisposing factors such as gender, age, and education status; enabling factors such as region and monthly household income; consumer need for health information; and attitude to health. Multiple logistic regression analysis was used to evaluate the association between utilization rate and the potential predictors. Results: Thirty-nine percent of consumers had obtained health information on the Internet over a one-year period. The utilization rates were higher for consumers who were young, educated, worked in the office setting, had higher incomes, wanted health information, and were able to use the Internet. The utilization rate was 5.35 times higher in the younger group (20-30 years) than in the elderly group (95% CI=2.21-12.97); 2.21 times higher for office workers than for manual workers (95% CI=1.16-4.20); 3.61 times higher for college graduates than for middle school graduates and below (95% CI=1.07-11.59); 1.99 times higher for people with monthly household incomes over 3,000,000 won than for those with monthly household incomes below 1,500,000 won (95% CI=1.01-3.92). Conclusions: There needs to be a paradigm shift, with consideration of not only Internet accessibility in the digital age, but also consumer ability and attitudes toward utilization of health information.

Purpose: To present our experience with soft tissue reconstruction using anterolateral thigh free flap after resection of soft tissue sarcoma. Materials and Methods: Between January of 2003 and June of 2007, we treated 7 patients with soft tissue reconstruction using anterolateral thigh free flap after wide resection for soft tissue sarcoma. We retrospectively analyzed type and size of tumors, resection margin, size of defect after resection, time of operation, flap survival and complication. Results: The type of sarcoma was 3 synovial sarcoma, 2 malignant fibrous histiocytoma, 1 leimyosarcoma and 1 fibrosarcoma. The size of tumor varied from $3{\times}5\;cm$ to $7{\times}8\;cm$. The resection margins of tumors were negative in all cases. The size of soft tissue defect after resection varied from $6{\times}8\;cm$ to $15{\times}10\;cm$. The mean time of operation was 3.6 hours. All flaps were survived. Conclusion: Anterolateral thigh free flap appear to be ideal for reconstruction after wide resection of soft tissue sarcoma.

Objectives : The aims of this study were to estimate the antihypertensive medication adherence in people with a disability and a history of taking antihypertensive medication, and to identify the factors affecting medication adherence. Methods : The National Health Insurance claims data were linked with the National Disability Registry. People with a disability, who received a prescription of antihypertensives, were identified from a total of 85,098 cases. Cumulative medication adherence (CMA) was used as an indicator of medication adherence. A CMA > 80% was defined as appropriate medication adherence. Multiple logistic regression analysis was used to identify the factors affecting medication adherence. Results : The average CMA in a total of 85,098 patients was 79.5%. The appropriate adherence $(CMA{\geq}80%)$ rate was 54.5% and 20.5% of patients had a CMA < 50%. Multiple logistic regression analysis revealed that the probability of appropriate adherence decreased with decreasing number of prescription days per visit, increasing number of providers, the patients' residential area moving from urban to rural areas, and when patients have an internal organ disability, auditory impairment, mobility impairment. Conclusions : The adherence to antihypertensive medication in people with a disability is influenced by various socio-economic, clinical and regional factors. In particular, the disabled who have locomotive and communication disabilities and internal organ impairments have a higher probability of under-adherence to antihypertensive medication adherence in Korea.
