It has frequently been reported that exposure to artificial light at night (ALAN) may cause negative health effects, such as breast cancer, circadian phase disruption and sleep disorders. Here, we reviewed the literature assessing the effects of human exposure to ALAN in order to list the health effects of various aspects of ALAN. Several electronic databases were searched for articles, published through August 2014, related to assessing the effects of exposure to ALAN on human health; these als

INTRODUCTION: Cameroon is classified by the World Health Organization (WHO) as having a critical shortage of health personnel. This is further complicated by the geographic distributional inequalities of the national health workforce. This shortfall impedes Cameroons' progress of improving the human resources for health (HRH) to meet up with the Millennium Development Goals (MDGs) by 2015. However, it is unknown whether the health workforce of Cameroon is distributed equally across geographic re

The study indicated that genetic and some environmental or socioeconomic factors might be important in the development of asthma and allergic diseases among preschool children in Korea through the web-survey.

Since May 20, 2015, when the first case of Middle East respiratory syndrome (MERS) in South Korea was confirmed, the cluster case in South Korea has grown to become the largest observed case following Saudi Arabia within the span of one month. Akin to what was observed in the Middle East, confirmed cases were infected through nosocomial transmission where the cluster is largely limited to patients, healthcare workers, and visitors to patients in healthcare facilities with confirmed cases. A majo

Abstract Background Along with the rapid transmission of COVID-19, adherence to preventive behaviours plays a crucial role with respect to the control of COVID-19. However, different individuals’ psychological characteristics and risk perception result in various forms of response to preventive behaviours. Based on the Health Belief Model, this study identifies the factors associated with preventive behaviours towards COVID-19 in South Korea during the initial stage of the COVID-19 pandemic. Met

This study presents a descriptive account of ratings based on psychometric variables of perceived twenty-five health risk factors, their information sources and the confidence in the information sources among Cameroonians nationwide. Health risk factors such as HIV/AIDS, natural disasters, terrorism, unprotected sex, unemployment, alcohol consumption, street crime, cigarette smoking, poverty, malaria, cholera and motorcycle accidents were among the greatest perceived health risk factors by the p

In this study, the difference between the risk perception of electromagnetic waves from cellular phones and the risk perception of other factors such as environment and food was analyzed. The cause of the difference in the psychological and social factors that affect the group with high risk perception of electromagnetic waves was also analyzed. A questionnaire survey on the risk perception of electromagnetic waves from cellular phones was carried out on 1001 subjects (men and women) over the ag

시판되고 있는 염모제 중 주로 포함되는 화학물질 3가지(p-phenylenediamine, p-aminophenol, m-aminophenol)를 함유한 제품 21제품의 화학염모제와 식물성을 모두 포함한 식물성 염모제 22제품을 선정하여 실험한 결과 3개의 화학물질의 유해 함량 평균값은 화학 염모제에 비해 식물성 염모제가 높았다. 화학 염모제와 컬러 헤나를 제조국별로 나누어 3가지 물질을 유해 함량의 평균값을 살펴 본 결과는 다음과 같다. 화학 염모제는 국내 제조 및 수입 된 염모제의 화학물질의 평균값의 차이는 없었으나 제조국인 인도인 식물성 염모제에서 p-phenylenediamine, p-aminophenol, m-aminophenol 모두 높게 나타났다. 색상에 따른 화학 염모제와 식물성 염모제의 차이는 블랙색상은 p-phenylenediamine, p-aminophenol, m-aminophenol의 물질에서 식물성 헤나의 평균 함량이 높았고, 특히 p-phenylenedia

A Middle East respiratory syndrome (MERS) -coronavirus (CoV) cluster that attacked Korea in May 2015 revealed several weaknesses in Korea's health care system in the face of the crisis of an emerging infectious disease and its public health implications. This experience has shown that is necessary to prepare comprehensive countermeasures through the cooperation of civil and public agencies to prevent a second or even third MERS outbreak and to control future crises of infectious disease and publ

This study examines differences between the level of objective knowledge regarding radio-frequency electromagnetic fields (RF-EMF) and risk perception of cell phones in Korea. We also investigate the extent to which socio-demographic factors, perceived EMF exposure, objective knowledge regarding EMF, and psychological factors influence the risk perception of cell phones using hierarchical multiple regression. All 3393 study subjects completed a survey measuring the degree of risk perception of E
