ABSTRACT
Purpose@#This study was conducted to evaluate the validity of the Gene-Health application in terms of estimating energy and macronutrients. @*Methods@#The subjects were 98 health adults participating in a weight-control intervention study. They recorded their diets in the Gene-Health application, took photographs before and after every meal on the same day, and uploaded them to the Gene-Health application. The amounts of foods and drinks consumed were estimated based on the photographs by trained experts, and the nutrient intakes were calculated using the CAN-Pro 5.0 program, which was named ‘Photo Estimation’. The energy and macronutrients estimated from the Gene-Health application were compared with those from a Photo Estimation. The mean differences in energy and macronutrient intakes between the two methods were compared using paired t-test. @*Results@#The mean energy intakes of Gene-Health and Photo Estimation were 1,937.0 kcal and 1,928.3 kcal, respectively. There were no significant differences in intakes of energy, carbohydrate, fat, and energy from fat (%) between two methods. The protein intake and energy from protein (%) of the Gene-Health were higher than those from the Photo Estimation. The energy from carbohydrate (%) for the Photo Estimation was higher than that of the Gene-Health. The Pearson correlation coefficients, weighted Kappa coefficients, and adjacent agreements for energy and macronutrient intakes between the two methods ranged from 0.382 to 0.607, 0.588 to 0.649, and 79.6% to 86.7%, respectively. @*Conclusion@#The Gene-Health application shows acceptable validity as a dietary intake assessment tool for energy and macronutrients. Further studies with female subjects and various age groups will be needed.
ABSTRACT
OBJECTIVES: In this study, we strived to determine the possibility of socioeconomic welfare in oral healthcare by analyzing the National Health Insurance (NHI) coverage rate. To date, efforts to realize the “social economy” of healthcare are active. While oral disease is common and chronic among Koreans, the rate of NHI coverage of dental clinics is substantially lower than that of the medical clinics. METHODS: We defined the NHI coverage of dental clinics as a proxy for “social skills” to improve oral health problems. The data were collected through a comparative analysis of the NHI coverage of dental clinics and that of non-dental clinics, in health welfare social cooperatives. RESULTS: The NHI coverage rate of the dental clinics in health welfare social cooperatives ranged from 0.97 to 2.62 times that of the non-dental clinics in health welfare social cooperatives. CONCLUSIONS: In conclusion, responsible management is recommended for making health welfare social cooperatives meaningful as a social economy.

The arterial pressure is regulated by the nervous and humoral mechanisms. The neuronal regulation is mostly carried out by the autonomic nervous system through the rostral ventrolateral medulla (RVLM), a key area for the cardiovascular regulation, and the humoral regulation is mediated by a number of substances, including the angiotensin (Ang) II and vasopressin. Recent studies suggest that central interleukin-1 (IL-1) activates the sympathetic nervous system and produces hypertension. The present study was undertaken to elucidate whether IL-1 and Ang II interact in the regulation of cardiovascular responses to the stress of hemorrhage. Thus, Sprague-Dawley rats were anesthetized and both femoral arteries were cannulated for direct measurement of arterial pressure and heart rate (HR) and for inducing hemorrhage. A guide cannula was placed into the lateral ventricle for injection of IL-1 (0.1, 1, 10, 20 ng/2mul) or Ang II (600 ng/10mul). A glass microelectrode was inserted into the RVLM to record the single unit spike potential. Barosensitive neurons were identified by an increased number of single unit spikes in RVLM following intravenous injection of nitroprusside. I.c.v. IL-1beta increased mean arterial pressure (MAP) in a dose-dependent fashion, but HR in a dose-independent pattern. The baroreceptor reflex sensitivity was not affected by i.c.v. IL-1beta. Both i.c.v. IL-1alpha and beta produced similar increase in MAP and HR. When hemorrhage was induced after i.c.v. injection of IL-1beta, the magnitude of MAP fall was not different from the control. The IL-1beta group showed a smaller decrease in HR and a lower spike potential count in RVLM than the control. MAP fall in response to hemorrhage after i.c.v. injection of Ang II was not different from the control. When both IL-1 and Ang II were simultaneously injected i.c.v., however, MAP fall was significantly smaller than the control, and HR was increased rather than decreased. These data suggest that IL-1, a defense immune mediator, manifests a hypertensive action in the central nervous system and attenuates the hypotensive response to hemorrhage by interaction with Ang II.
