BACKGROUND: This study was performed to better assess the perceptions, motivating factors, and behaviors associated with the use of hand washing to prevent H1N1 influenza transmission during the peak pandemic period in Korea. METHODS: A cross-sectional survey questionnaire was completed by 942 students at a university campus in Suwon, Korea, between December 1 and 8, 2009. The survey included questions regarding individual perceptions, motivating factors, and behaviors associated with hand washi

PURPOSE: The aim of this study was to investigate whether a diagnosis of cancer has an impact on the cancer patients' job loss and re-employment and to identify the factors affecting job loss and re-employment during 6 years of follow-up of Korean employees with cancer. PATIENTS AND METHODS: All employees except for the self-employed in Korea who were diagnosed with cancer during the 2001 calendar year (n = 5,396) were identified as the first baseline patients and were followed every 3 months ov

BACKGROUND: Cancer diagnosis may adversely affect employment status. Our aim was to investigate whether cancer diagnosis effects employment status by comparing employment status changes in cancer patients with to that of cancer-free workers over a 5-6-year period. METHODS: All 25-55-year-old, non-self-employed, Korean workers who were diagnosed with cancer for the first time in 2001 were identified as first baseline study subjects (n=4991). Of these, those who lost their jobs within 1 year of ca

OBJECTIVE: The current study examined the prevalence and associated factors of suicidality among Korean cancer patients. Moreover, the association of multiple psychological morbidities with suicidality was investigated among cancer patients. METHODS: A cross-sectional, multi-center survey of 400 cancer patients was administered in five cancer-treatment hospitals throughout South Korea. Study variables were assessed using standardized measures including the Mini International Neuropsychiatric Int

BACKGROUND: With the rapid aging of populations around the world, dementia has become one of the most important public health problems in Eastern Asian countries. The purpose of the present study was to provide an estimate of the burden of dementia and forecast its future burden, as generalized to the Korean population, and to provide detailed gender- and age-specific information regarding the burden of dementia in the elderly population of Korea. METHODS: 'Disability-adjusted life years' (DALYs

BACKGROUND: As the number of working cancer patients increases, workplace discrimination and its relationship to changes in employment status among cancer patients is becoming an increasingly important social concern. The aim of this study is to provide a comprehensive overview of the relationship between changes in employment status and discrimination following a diagnosis of cancer. METHODS: A total of 748 cancer patients, aged 18 years and older, who were employed before receiving a diagnosis

In this paper, we propose a new in-plane XYθz nano-positioning stage that utilizes piezoelectric actuators and flexure mechanisms. The proposed stage has an aperture and is compact, which facilitates its application in measurement equipment, especially those used for biological specimens. The stage has four piezoelectric actuators and four bridge-type flexure mechanisms, which are used to amplify the small motions produced by the piezoelectric actuators. This paper describes the modeling and des
