Purpose: This study identified effects of dietary and physical activity interventions including dietary interventions or physical activity interventions alone or combined dietary-physical activity interventions to improve symptoms in metabolic syndrome including abdominal obesity, high triglycerides, low high density lipoprotein cholesterol, elevated blood pressure, and elevated fasting glucose through meta-analysis. Methods: Articles on metabolic syndrome X published from 1988 to 2013 were searched through electronic databases, Google Scholar, and reference reviews. Methodological quality was assessed by the checklist, SIGN (Scottish Intercollegiate Guidelines Network). Results: In the meta-analysis, there were 9 articles reporting 13 interventions with 736 participants. Using random effect models, the dietary and/or physical activity interventions showed a lower mean difference in waist circumference ( - 1.30 cm, 95% CI: - 2.44~ - 0.15, p =.027). The combined dietary-physical activity interventions showed a lower mean difference in waist circumference ( - 2.77 cm, 95% CI: - 4.77~ - 0.76, p =.007) and systolic blood pressure ( - 5.44 mmHg, 95% CI: - 10.76~ - 0.12, p =.044). Additionally, interventions of over 24 weeks yielded a lower mean difference in waist circumference ( - 2.78 cm, 95% CI: - 4.69~ - 0.87, p =.004) and diastolic blood pressure ( - 1.93 mmHg, 95% CI: - 3.63~ - 0.22, p =.026). Conclusion: The findings indicate that dietary and/or physical activity interventions for metabolic syndrome reduce central obesity with no adverse effects. This finding provides objective evidences for dietary and physical activity management on metabolic syndrome as an efficient intervention.

Purpose: We present improvements to the Korean home visiting healthcare service based on analysis of Korean home visiting healthcare services considering recent sociodemographic changes and demands for healthcare services. Methods: This is a review study in which the results are derived through a literature review and data analysis. We collected data through a search of electronic databases, Google Scholar, and governmental websites. Results: Changes in Korean home visiting healthcare services are classified into four stages: ‘introduction (1990–2000)’, ‘pilot project (2003-2006)’, ‘nationwide expansion (2007–2012)’, ‘various types (2013–2018)’. Korean home visiting healthcare service based on public health centers has achieved outcomes such as improved health behavior and health management, increased health management ability, and establishment of comprehensive healthcare infrastructure. Conclusion: In the future, the demand for home visiting healthcare service will increase steadily because of deepening social polarization, rapid aging of the population, and increases in chronic diseases. To improve health management and health equity, we suggest that Korean home visiting healthcare service will expand to all the people as a core public health service. It is necessary to establish a management team for various types of home visiting healthcare service in the public health center.

이건아(Guna Lee) 한국산학기술학회 2021 한국산학기술학회논문지 Vol.22 No.1
본 연구의 목적은 가임기 여성의 규칙적 운동 및 운동의 종류에 따른 대사증후군 간의 관련성을 파악하여 효과적인 대사증후군 예방 및 관리 중재 개발을 위한 기초자료를 제공하고자 한다. 본 연구는 제7기 3차년도 국민건강영양조사 원시자료(KNHANES Ⅶ-3, 2018년)를 이용하여 만 19세 이상 가임기 여성 4172명을 대상으로 시행하였으며, 규칙적 운동의 종류에 따른 대사증후군 구성요소의 차이는 복합표본 t검정으로, 규칙적 운동의 종류가 영향을 미치는 대사증후군의 유병 위험은 복합표본 다중 로지스틱 회귀분석으로 분석하였다. 가임기 여성의 대사증후군 유병률은 3.1%(128명)이었으며 가임기 여성 중 규칙적 운동 실천군은 1979명(46.5%)이었다. 가임기 여성의 규칙적 운동 실천군은 미실천군과 비교하여 다섯 가지 대사증후군 구성요소 중 수축기 혈압(p =.002), 허리둘레(p<.001)와 공복혈당(p =.007)가 상대적으로 낮았으며 고밀도콜레스테롤(p < .001)는 상대적으로 높았다. 규칙적 운동중 규칙적 근력운동 실천군은 규칙적 근력운동 미실천군과 비교하여 수축기 혈압(p < .001), 이완기 혈압(p = .005), 허리둘레(p < .001), 공복혈당(p < .001)과 중성지방(p = .015) 모두 상대적으로 낮았고 고밀도콜레스테롤(p < .001)은 상대적으로 높았다. 대사증후군에 영향을 미치는 혼란 변수들을 통제한 후, 규칙적 운동 실천군(유병교차비 0.59, 95% 신뢰구간 0.35-0.98, p = .040)과 규칙적 근력운동 실천군(유병교차비 0.34, 95% 신뢰구간 0.14-0.80, p= .013)은 각각 미실천군과 비교하여 대사증후군 유병위험이 낮게 나타났다. 그러므로 규칙적 운동은 가임기 여성의 대사증후군 유병 위험을 낮추는 중요한 변수임을 알 수 있으며, 가임기 여성의 대사증후군 예방 및 관리를 위한 운동 중재 개발 시 근력운동을 포함할 필요가 있음을 제언한다. The purpose of this study was to identify the association between regular physical activity (PA) types and metabolic syndrome (MetS) in fertile women. Data were obtained from the seventh Korea National Health and Nutrition Examination Survey (KNHANES Ⅶ-3, 2018). The sample consisted of 4,172 fertile women over 19 years of age. The data were analyzed using an independent t-test, χ2 test, and multiple logistic regression analysis for examining the association of regular PA and MetS. The prevalence of MetS in fertile women was 3.1% (n =128), and 1,972 fertile women (47.2%) practiced regular PA. Compared to the non-regular PA group, regular PA resulted in a significantly lower systolic blood pressure (p =.002), lower waist circumference (p <.001), lower fasting blood sugar (p =.007), and higher high-density lipoprotein cholesterol (p <.001). After controlling the confounding variables, multiple logistic regression showed that the regular PA group (odds ratio 0.59, 95% confidence interval 0.35-0.98, p =.040) and the regular muscle-strengthen PA group (odds ratio 0.34, 95% confidence interval 0.14-0.80, p =.013) were associated with a decreased risk of MetS. Therefore, regular PA, including muscle-strengthen PA should be considered to develop effective MetS intervention in fertile women.

Lightning is one of hazards affecting the rapid-transit railway system. There are two effects, which are direct lightning surge to electric car line and induced lightning surge. Protection methods for the direct lightning surge are studied with various occasions, however, study of induced lightning surge is insufficient in spite of a large or small effects. In this paper, it is analysed the way that serge voltage is induced to electric car line by lightning strikes. By modeling the propagation process and the coupling phenomenon of electromagnetic wave produced by lightning strikes, it is achieved to make integrative circuit model combined with existing electric car model. The study is conducted into three different waveform of electromagnetic wave produced by lightning; rectangular wave, double exponential distribution wave, triangle wave. It is also simulated that the inducing serge is coupled to electric car line in an arbitrary location. The simulation results in that, when rapidly changing rectangular wave is supplied, maximum power is induced to electric car line.

Microalgae have survival strategies that are acclimated in various environmental stress factors such as salinity, heavy metal and radionuclide effluence. This study was identified the resistance of cesium chloride in various microalgae and selected acclimation organisms. The selected organisms were measured growth curve by spectrophotometer. The minimum ion condition of microalgae culture using LED light was determined by the growth curve and pH.

Objective : As treatments for breast cancer require long period of time, the patients need continuous monitoring and management of their health related quality of life. The purpose of this preliminary study is to explore the utility of monitoring quality of life using a mobile phone based application, which was developed to enable the patients to report daily quality of life more efficiently. Methods : Department of psychiatry, breast cancer center and U-health team of Asan Medical Center collaborated in developing a mobile application titled 'DugunDugun'. Through the application, patients with breast cancer receiving neo-adjuvant chemotherapy could report on various questions about their daily quality of life. We extracted and explored the daily basis of the data of sleep duration, number of awake, sleep satisfaction, mood and anxiety from nine patients who reported on the questionnaire for more than a month. Results : The longitudinal data collected using our mobile application well represented the characteristics of individual sleep patterns and daily emotional changes. Most of the patients showed high daily variations in the scores of their quality of life while their averaged scores were similar among patients. The patient with highest daily variations in the subjective sleep quality and daily emotional change had highest score corresponding to moderate depression in Beck Depression Inventory (BDI). Conclusion : The results suggest that mobile application could be a useful tool for monitoring and collecting the daily quality of life in the patients with breast cancer. We expect that mobile application could facilitate early detection and proper intervention for the cancer patients at psychological crisis.
