An Extension of Migration Effectiveness Indices
This study introduces the age‐weighted migration effectiveness index (AWMEI), a new metric that integrates age‐specific variation into a single measure of migration effectiveness. Traditional indices, such as the migration effectiveness index (MEI) and age‐specific MEI (ASMEI), effectively address the first aspect of migration effectiveness—population redistribution—but overlook the second aspect—transformation of the composition of regional popu…
Circadian phase advances in children during camping life according to the natural light-dark cycle
Background It is known that the circadian rhythm phase in adults can be advanced in a natural light-dark cycle without electrical lighting. However, the effect of advanced sleep-wake timing according to the natural light-dark cycle on children's circadian phase is unclear. We investigated the effects of approximately 2 weeks of camping life with little access to artificial lighting on children's circadian phases. We also conducted an exploratory …
Intake of l-serine before bedtime prevents the delay of the circadian phase in real life
Background It has been shown in laboratory experiments using human subjects that ingestion of the non-essential amino acid l-serine before bedtime enhances the advance of circadian phase induced by light exposure the next morning. In the present study, we tested the effect of ingestion of l-serine before bedtime on circadian phase in real life and whether its effect depends on the initial circadian phase. Methods The subjects were 33 healthy male…
Is the use of high correlated color temperature light at night related to delay of sleep timing in university students? A cross-country study in Japan and China
BackgroundBlue-enriched white light at night has the potential to delay the circadian rhythm in daily life. This study was conducted to determine whether the use of high correlated color temperature (CCT) light at home at night is associated with delay of sleep timing in university students.MethodsThe survey was conducted in 2014-2015 in 447 university students in Japan and 327 students in China. Habitual sleep timing and type of CCT light at hom…
Effects of risk factors for and components of metabolic syndrome on the quality of life of patients with systemic lupus erythematosus
Feasibility, comparability, and reliability of the standard gamble compared with the rating scale and time trade-off techniques in Korean population
Psychometric properties of the EQ-5D-5L in the general population of South Korea
Comparing the psychometric properties of the EQ-5D-3L and EQ-5D-5L in cancer patients in Korea
Determinants of hospital closure in South Korea
A Generalized Significance Testing Method for Global Measures of Spatial Association
This research is concerned with providing a generalized significance testing method for global measures of spatial association by extending the Mantel test. Even though it has long been recognized that univariate spatial association measures such as Moran's I and Geary's c are special cases of Mantel's generalized association statistic, an intensive and comprehensive examination of the connections, particularly in terms of significance testing ha…
Knowledge of, Attitudes Toward, and Experience of Complementary and Alternative Medicine in Western Medicine– and Oriental Medicine–Trained Physicians in Korea
Objectives. We compared knowledge of, attitudes toward, and experience with complementary and alternative medicine (CAM) among Western medicine–trained doctors (WMDs) and Oriental medicine–trained doctors (OMDs). Methods. In Korea, 502 WMDs and 500 OMDs were interviewed with a structured questionnaire. Results. OMDs held more favorable attitudes toward CAM than did WMDs. OMDs possessed a deeper understanding of and greater experience with CAM. OM…
