This study aimed to investigate the differences in the upper and lower limits of the 95% distribution of fasting blood glucose (FBG) by age groups. We also analyzed the changes in the mean values and dispersion of the data using the Korean Blood Glucose Reference Standard raw data published by the National Health Insurance Service (NHIS). Furthermore, the trends among 16 administrative districts were analyzed and any gender differences were determined. We also assessed whether the study results correlated with the relative standard uncertainty, as published by the NHIS. On the dispersion analysis using the differences between the upper and lower limits of the 95% distribution of FBG by age group, there were significant differences across gender and administrative districts (P<0.05). The gender differences in FBG measurements, as published by the NHIS, were significant across different administrative districts and age groups (P<0.001). This confirmed the need to recalculate the blood glucose reference standards for men and women. No significant correlation was observed between the relative standard uncertainty, as published by NHIS, and the dispersion and number of measurements analyzed in this study. However, it showed a high correlation with the measured mean value (R²=0.95). Therefore, further research on the reference standard and uncertainty is needed.

This study was conducted to develop a severity-adjusted LOS(Length of Stay) model for knee replacement patients and identify factors that can influence the LOS by using the Korean National Hospital Discharge in-depth Injury Survey data. The comorbidity scoring systems and data-mining methods were used to design a severity-adjusted LOS model which covered 4,102 knee replacement patients. In this study, a decision tree model using CCS comorbidity scoring index was chosen for the final model that produced superior results. Factors such as presence of arthritis, patient sex and admission route etc. influenced patient length of stay. And there was a statistically significant difference between real LOS and adjusted LOS resulted from health-insurance type, bed size, and hospital location. Therefore the policy alternative on excessive medical utilization is needed to reduce variation in length of hospital stay in patients who undergo knee replacement.

This study aimed to identify nurses' participation motivation, its influence factors, and their job training need. A survey was conducted on 345 nurses of general hospitals in Gyeonggi-do. Data was collected from October 5th to 18th, 2016 and was analyzed through t-test, ANOVA, Bonferroni post-test, and multiple regressions using SPSS 21.0. Participation motivation was high in 'expertise capability improvement and development' and low in personal gain and job stability. Job training need was the highest in nosocomial infection management and CPR and was the lowest in hospice and rehabilitation nursing. Participation motivation had significant differences depending on age, marital status, educational level, and clinical experience, and was influenced by the job training need of professional nursing and medical knowledge for disease treatment. Therefore, it is necessary to plan medical educational programs to enhance job training effectiveness, establish a strategy to increase participation motivation; and expand various job training support.

Measured values may differ between Multi-Dimensional Voice Program (MDVP), Praat, and Time-Frequency Analysis software (TF32), all of which are widely used in voice quality analysis, due to differences in the algorithms used in each analyzer. Therefore, this study aimed to compare the values of parameters of normal voice measured with each analyzer. After tokens of the vowel sound /a/ were collected from 35 normal adult subjects (19 male and 16 female), they were analyzed with MDVP, Praat, and TF32. The mean values obtained from Praat for jitter variables (J local, J abs, J rap, and J ppq), shimmer variables (S local, S dB, and S apq), and noise-to-harmonics ratio (NHR) were significantly lower than those from MDVP in both males and females (p<.01). The mean values of J local, J abs, and S local were significantly lower in the order MDVP, Praat, and TF32 in both genders. In conclusion, the measured values differed across voice analyzers due to the differences in the algorithms each analyzer uses. Therefore, it is important for clinicians to analyze pathologic voice after understanding the normal criteria used by each analyzer when they use a voice analyzer in clinical practice.

Nowadays, dental tourism becomes phenomenon because of its cost-effectiveness, improvement of quality and technology, dental infrastructure, and attractive tourism. Korea as one of popular destination country had established dental system. On the other hand, Indonesia with high number of population is potential market for dental tourism. The aim of this study is to compare the knowledge, attitude, and experience towards dental tourism among Indonesian and Korean. Two cross-sectional descriptive surveys were conducted to collect the data. This study was used one questionnaire in two different languages due to nature of the study population. Data from a total 923 of Indonesian from 33 provinces in Indonesia was collected during the period from April through July 2010. On the other hand, during May until August 2010 data from a total of 312 Korean were obtained. It was found that the majority of participants in both countries had never heard about dental tourism. Among those who had heard about dental tourism, the most common source was internet. Ownership of dental insurance had significant relationship with knowledge of dental tourism among Indonesian while level of education and monthly internet usage had it among Korean (p<0.05). Attitudes of Indonesian and Korean people about dental tourism were negative due to assumption that dental services in their home country were satisfactory. 100% of Korean had no experience on dental treatment in other countries while 2.4% of Indonesian had experience with it. In conclusion, regarding all these evidences, comprehensive and positive information about dental tourism is needed to enhance people's knowledge, attitude, and experience.

With the rapid development of the Internet, public agencies and private companies introduced 'IT outsourcing in order to maintain and repair the information systems. Also they have utilized the SLA in order to manage it. Although IT outsourcing as a way to promote effective SLA are being introduced, the introduction of service level agreements or those introduced universal effectiveness did not demonstrate in the public agencies. The importance of outsourcing in the information systems is growing, but the increase in size of the business information, IT technology diversification, expansion of information between systems interconnection, information system operating and maintenance costs with the increase of information systems to streamline operations, increase the need for versatility is growing gradually. In this paper we investigates IT outsourcing in public agencies as a way to promote effective service level agreement(SLA) with the introduction and consideration, and through the application of SLA mutual customers and IT service organizations make a clear point of management and IT service levels and IT services for improved mind and strengthen the effectiveness of preventive activities can be seen.

The purpose of this study is to identify a potential user's need for use and operational of the elderly day care center and to identify the problems and suggest development directions. The data collection was conducted on 320 ordinary people living in J-do through a questionnaire, and sought to understand the operational status of in-depth interview institutions for the heads and employees of six center. As a result of the analysis, a potential user's ware not aware of the functions and specific roles of day care center, the cost of facilities was covered by the government, and that facilities and the environment were important factors when using the center. In-depth interviews show that the current policy or system is far from reality and does not fit the status or role of the workers and the operational status of the agency, requiring the re-establishment of the on-site system. Based on the research results, the development direction of day care facilities requires active promotion and strengthening of family support for improving and enhancing awareness of day care facilities to citizens at the national level. Second, the quality of nursing services should be enhanced through improvements in facilities and the environment that reflect users' needs. Third, The government should improve the quality of nursing services by improving the poor employment conditions and treatment of workers to fit the reality.

PURPOSE. To determine the effect of fibronectin (FN)-conjugated, microgrooved titanium (Ti) on osteoblast differentiation and gene expression in human bone marrow-derived mesenchymal stem cells (MSCs). MATERIALS AND METHODS. Photolithography was used to fabricate the microgrooved Ti, and amine functionalization (silanization) was used to immobilize fibronectin on the titanium surfaces. Osteoblast differentiation and osteoblast marker gene expression were analyzed by means of alkaline phosphatase activity assay, extracellular calcium deposition assay, and quantitative real-time PCR. RESULTS. The conjugation of fibronectin on Ti significantly increased osteoblast differentiation in MSCs compared with non-conjugated Ti substrates. On the extracellular calcium deposition assays of MSCs at 21 days, an approximately two-fold increase in calcium concentration was observed on the etched 60-${\mu}m$-wide/10-${\mu}m$-deep microgrooved surface with fibronectin (E60/10FN) compared with the same surface without fibronectin (E60/10), and a more than four-fold increase in calcium concentration was observed on E60/10FN compared with the non-etched control (NE0) and etched control (E0) surfaces. Through a series of analyses to determine the expression of osteoblast marker genes, a significant increase in all the marker genes except type I collagen ${\alpha}1$ mRNA was seen with E60/10FN more than with any of the other groups, as compared with NE0. CONCLUSION. The FN-conjugated, microgrooved Ti substrate can provide an effective surface to promote osteoblast differentiation and osteoblast marker gene expression in MSCs.

Purpose: The purpose of this study was to estimate the clinical utilization of radiation therapy (RT) in Korea between 2009 and 2013. Materials and Methods: We analyzed open claims data from the Health Insurance Review and Assessment Service. The subjects were patients who had diagnostic codes C00-C97 or D00-D48 according to the 10th revision of the International Classification of Diseases, with procedure codes indicating RT treatment. Results: The total number of patients who received RT in 2009, 2010, 2011, 2012, and 2013 were 45,571, 49,593, 54,671, 59,172, and 61,485, respectively. Among them, the total numbers of male and female patients were 20,780/24,791 in 2009, 22,711/26,882 in 2010, 24,872/29,799 in 2011, 27,101/32,071 in 2012, and 27,941/33,544 in 2013. The five cancers that were most frequently treated with RT between 2009 and 2012 were breast, lung, colorectal, liver, and uterine cervical cancers. However, the fifth most common cancer treated with RT that replaced uterine cervical cancer in 2013 was prostate cancer. The three leading types of cancer among the male patients were lung, colorectal, and liver cancers, whereas in female patients, they were breast, uterine cervical, and lung cancers. The type of cancer most commonly treated by RT was cancer of the central nervous system in patients aged 20 years or less, breast cancer in patients aged 30-50 years, and lung cancer in patients aged 60 years or more. Conclusion: Data from this study provided the clinical utilization of RT in Korea between 2009 and 2013.
