  • Purpose: Since 1994, Asian Health Services, the Korean American Community Advisory Board, and the Center for Family and Community Health (University of California at Berkeley) have conducted periodic, population-based surveys on Korean American community health in Alameda County, California. The present study examines changes in health care access and utilization between 1994 and 2002 among Korean American adults in Alameda County, California. Method: We reanalyzed data from the 1994 and 2002 Korean Health Surveys. The primary variables of interest, health care access and utilization, were operationalized in terms of health insurance coverage, routine check-ups, a usual source of health care and reported barriers to health care. The frequency distribution of each indicator was calculated and its standard error was estimated using SUDAAN. The differences between 1994 and 2002 were examined with chi-square test. Results: Compared to 1994, Korean Americans in Alameda County were more likely to have health insurance coverage in 2002 (74.0% vs. 82.7%). Korean Americans in Alameda County were more likely to have received a recent (prior two years) routine health checkup in 2002 (50.4% vs. 57.2%). Health checkups increased over time for males, for adults with more than 12 years of education, and for employed adults. Also, compared to 1994, employed adults were more likely to have a usual source of health care in 2002 (66.5% vs. 78.4%). In both 1994 and 2002, high cost (58.0% vs. 47.8%) was the most commonly cited barrier to health care, and the next most frequently cited barriers were language (29.2% vs. 27.7%) and no time (29.2% vs. 30.3%). Conclusion: To improve health care utilization and health conditions, it is important to investigate factors related to health care and to monitor changing trends. Ongoing surveillance of health-related factors can contribute to the development of health education programs to reduce morbidity and mortality due to chronic disease, and thereby lead to improvements in health status among Korean Americans.

  • For an unbiased TF (Tansfer Function) estimations we investigate geomagnetic TF derived from ICHEON and YONGIN sites, employing RR (Remote Reference) and SNS (Signal Noise Separation) techniques. The Rh technique, which requires synchronized field variations recorded at a clean remote site, is a reliable method to minimize the bias of TF by uncorrelated noises in magnetic channels. Meanwhile, SNS technique based on the assumption of noise-free remote data can improve the signal-noise level by separating signal TF and noise TF, which is successfully applied to the environments with strong correlated noises. In this study, TF at YONGIN is analyzed using geomagnetic data from ICHEON site as a remote reference, which seem to have somewhat better data quality. The application of Rh technique reduces the bias of TF, which appears in single site robust estimation, and makes curves in the amplitude and phase of TF more smooth as frequency. Futhermore, in order to investigate noise source quantitatively, SNS technique is applied. The results of SNS suggest that dominant noise source seems to be located at western region of YONGIN. This noise source is considered to originate from railway system such as KTX and national subway. which passes through the west regions of YONGIN.

  • Commercially pure titanium (CP Ti) and Ti-6Al-4V alloys have been widely used for biomedical applications. However, the use of the Ti-6Al-4V alloy in biomaterial is then a subject of controversy because aluminum ions and vanadium oxide have potential detrimental influence on the human body due to vanadium and aluminum. Hence, recent works showed that the synthesis of new Ti-based alloys for implant application involves more biocompatible metallic alloying element, such as, Nb, Hf, Zr and Mo. In particular, Nb and Hf are one of the most effective Ti ${\beta}-stabilizer$ and reducing the elastic modulus. Plasma electrolyte oxidation (PEO) is known as excellent method in the biocompatibility of biomaterial due to quickly coating time and controlled coating condition. The anodized oxide layer and diameter modulation of Ti alloys can be obtained function of improvement of cell adhesion. Manganese(Mn) plays very important roles in essential for normal growth and metabolism of skeletal tissue in vertebrates and can be detected as minor constituents in teeth and bone. Radio frequency(RF) magnetron sputtering in the various PVD methods has high deposition rates, high-purity films, extremely high adhesion of films, and excellent uniform layers for depositing a wide range of materials, including metals, alloys and ceramics like a hydroxyapatite. The aim of this study is to research the Mn coatings on the micro-pore formed Ti-29Nb-xHf alloys by RF-magnetron sputtering for dental applications. Ti-29Nb-xHf (x= 0, 3, 7 and 15wt%, mass fraction) alloys were prepared Ti-29Nb-xHf alloys of containing Hf up from 0 wt% to 15 wt% were melted by using a vacuum furnace. Ti-29Nb-xHf alloys were homogenized for 2 hr at $1050^{\circ}C$. Each alloy was anodized in solution containing typically 0.15 M calcium acetate monohydrate + 0.02 M calcium glycerophosphate at room temperature. A direct current power source was used for the process of anodization. Anodized alloys was prepared using 270V~300V anodization voltage at room. Mn coatings was produced by RF-magnetron sputtering system. RF power of 100W was applied to the target for 1h at room temperature. The microstructure, phase and composition of Mn coated oxide surface of Ti-29Nb-xHf alloys were examined by FE-SEM, EDS, and XRD.

Method: The subjects of this study were two patients who were treated at the Y hospital in Gyeonggido. Data were gathered by VFSS regarding the degree of swallowing disability and oral intake before and after intervention. This study analyzed case studies of two patients. One patient's intervention was applied in September 2012 for three weeks. The other's intervention was applied in February 2014 for three weeks. At the first session, the VFSS examination was administered. Then, intervention began after the patients gave their consent for participation. Each session was practiced 10 times per set, but one session had 3 sets. Intervention frequency consisted of five sessions per week, and it was conducted for three weeks. Tongue self-resistance exercise included tongue protrusion, tongue lateralization, and tongue elevation on the hard palate. Results: The first tongue self-resistance exercise had a positive effect on swallowing function because of the decrease in VFS score. The second tongue self-resistance exercise showed improved oral intake based on FOIS scores. Conclusion: This study's results suggest that there are many benefits of tongue self-resistance exercise on the swallowing function when it is applied to patients with stroke.

  • This study was conducted to find the mediating effect of self-leadership in the relationship between academic self-efficacy and college-life satisfaction of Chinese students majoring in beauty. Surveys were answered by 400 Chinese students from July to August 2019 and analyzed as follows. We used the SPSS22.0 program and Process macro for SPSS to analyze the frequency, descriptive statistics, correlation analysis, and bootstrap method. The results of the analysis showed a positive correlation among the college-life satisfaction, self-leadership, and academic self-efficacy of Chinese students, and self-leadership acted as a partially mediating variable between academic self-efficacy and college-life satisfaction. Therefore, it was found that a higher college-life satisfaction and self-leadership resulted in a higher academic self-efficacy. Based on these results, in order to alleviate the problems of college life maladjustment and low learning efficiency of Chinese students majoring in beauty, the development of self-leadership education programs is becoming more important. This must be emphasized in the Edu-Tech era due to the need for customized education programs for international students amidst the COVID-19 pandemic.

  • This study aimed to specify Vessel Traffic System(VTS) operators' situational awareness(SA) tasks and examine differences in subjective ratings for three levels of SA. Data for relative frequencies of SA tasks were collected by using direct in field observation. Subjective rating scores were obtained using a questionnaire method and compared in terms of VTS operator's gender and length of service career. The results are as follows. First, it was found that the VTS operators perform information perception task elements more frequently than those for information integration and prediction. Second, VTS operators tended to show subjectively lower evaluation scores for prediction than information perception or integration. Third, male VTS operators rated their SA ability higher than females. Fourth, the male VTS operators more than 15 years of career service showed higher subjective rating scores than those with under 5 years of service. Female VTS operators with different levels of career service showed a similar level of subjective rating scores. These results suggest that the frequency of SA related tasks and subjective SA evaluation can differ in terms of SA levels and individual differences.
