Purpose: The purpose of this study was to examine the usage of CAD/CAM, which is one of dental technologist duties, in an effort to look for any possible changes in the usage of CAD/CAM. It's specifically meant to compare the results of this study with those of Lee Jong-do, Park Kwang-Sig(2011)'s study in March, 2011, to determine if there were any changes over the past four years. The selected variables that were investigated were the ownership of CAD/CAM, awareness of it, the route of acquiring the first information on it, the merits and demerits of its usage, usage experience and educational experience about it. Methods: An online survey was conducted on the dental technologists who worked in urban communities including metropolitan cities to find out the usage of CAD/CAM in 2015 from July 15 to 31, 2015, after existing questionnaire items were modified. The collected data were analyzed by IBM SPSS statistics 22.0, and statistical data on frequency, percentage, mean and standard deviation for each item were obtained. To figure out the characteristics of the subjects and the relationship between their occupational characteristics and the usage of CAD/CAM, crosstabs, independent-samples t-test and one-way ANOVA were utilized. As for the usage of CAD/CAM in 2011, the results of Lee Jong-do, Park Kwang-Sig(2011)'s study were selected, and then a comparative analysis was made. The level of significance was all set at .05. Total 250 questionnaires were distributed to them, and 190(76.0%) were returned. After excluding 23 whose answers were uncertain or seemed to lack reliability, total 167(66.8%) were used in final analysis. Results: As a result of analyzing the usage of CAD/CAM that was one of dental technologist duties, there was a great increase in the ownership of CAD/CAM in their workplaces from 2.4 percent in 2011 to 71.7 percent in 2015, and there was an improvement in awareness about it and the necessity of its usage as well. In 2011, the Internet and mass media were the most common route that they got to know about it. They had a strong tendency to acquire related knowledge through education in 2015, and there were some changes in the products that they used or preferred. In both years, the great merit of CAD/CAM was the simplified manufacturing process of restoration, and it had another great advantages in 2015 such as the improved quality of restoration or improved environments for dental technology. Concerning disadvantages, high price was a big problem in 2011. In 2015, not only price but the burden of material costs, frequent breakdown, poor demand among dental clinics and a lack of CAD/CAM professionals were pointed out a lot. In the future, this researcher intends to make research to seek ways of improving CAD/CAM professionals. Conclusion: There was more awareness of CAD/CAM in 2015 than in 2011 when the changes in awareness of it were analyzed, and the finding suggest the necessity of sustained education and concern.

도서관통계와 평가의 관련성이 국제표준안, 업무활동 영역, 항목간의 유사성 면에서 깊고, 불가분의 관계 속에 있음에도 한국 대학도서관의 통계와 평가는 생산단계 및 활용 면에서 전혀 연계되어 있지 않다. 이를 증명하기 위하여 국제표준, 통계데이터를 살펴 두 항목간에 연계적 상관관계를 살펴보아 정량적 데이터의 45%정도의 중복도가 있음을 밝혔다. 반면 기존의 국내 통계 항목과 평가 항목간에는 14-26%의 관계가 있으며, 새로이 연구 개발된 대학도서관통계 실용안에서는 상당히 발전된 관계성을 발견하였으며, 반면 상당한 특정성도 발견되었다. 이제 대학도서관통계 온라인시스템 개발단계에서 통계시스템의 목적 외에 평가시스템정보를 제공한다는 면을 고려하여 항목간의 포괄적 정보가 제공되도록 개발하는 것이 필요하다.

Purpose: The objective of this study was to examine patient safety culture (PSC) and patient safety initiatives (PSI) according to IT-based medication errors prevention system which is constructed in this study, and to identify the relationships among system construction, perception to the usage, PSC and PSI. Methods: The subjects were 180 nurses who work at 12 different hospitals with over 300 beds. The questionnaire included the characteristics of participants, a system construction status, the perception to the usage using electric pharmacopoeia (EP), a drug dose calculation system (DDCS), a patient safety reporting system (PSRS) and a bar-code system (BS). The data were collected from July 2011 to August 2011. Descriptive statistics, ANOVA, Pearson correlation and MANOVA were used for data analysis. Results: Systems were constructed in participating hospitals; For EP and PSRS, 83.9%, DDCS, 50%, and BS, 18.3%. The perceptions on the usage of the system were marked highest in BS as 4.54 followed by EP as 3.85. There were significant positive correlations between PSI and EP construction (r=.17, p=.028); PSRS (r=.17, p=.028) and DDCS (r=.23, p=.002). Conclusion: The developed system for improving the user experiences and reducing medication errors was found out well accepted. It is hoped that the system is helpful for PSC and PSI improvement in clinical settings.

The purposes of this study were 1) to investigate usage level of production strategies based on group of production environment, 2) to investigate usage level of production systems based on group of production strategy, and 3) to analyze each of company performance based on group of production strategy and system. For this study, the questionnaires were administered to 215 apparel manufactures in metropolitan area from Feb. to Mar. 1998. Employing a sample of 201, data were analyzed by factor analysis, descriptive statistics, cluster analysis, discriminant analysis, and multivariate analysis of variance. The following are the results of this study. 1. Concerning production strategy due to group of production environment, the stable group and the complicated group prefer to rice/quality centered strategy but the level of usage for strategies is so pretty that it is not significant to carry out them. 2. Concerning production system due to group of production strategy, the workers centered group is occupied high in the price/quality centered group & the complex group. And also the product centered system is occupied high in the flexibility centered group. 3. Concerning company performance due to group of production strategy and system, the price/quality centered group holds low position of performance comparing to another groups. And the performance of the managers centered group is higher than that of the workers.

Purpose: The purpose of this study was to investigate relationships between short sleep, obesity, and screen time. Methods: Data were obtained from a survey using a sample of 1,166 academic, and 597 vocational high school students. A structured questionnaire was used to assess demographics, hours spent in sleep, TV viewing, internet usage, and game playing. Obesity was determined using the body mass index. Descriptive statistics, Cochran Mantel Haenszel Chi-square test, and multiple logistic regression with dummy variables were performed. Results: Short sleep (<8 hours/day) was significantly related to obesity, not in academic school students, but in vocational school students. Academic high school students who had enough sleep (${\geq}8$ hours/day), had more time spent on TV viewing, internet usage, and game playing. Similar results were found in vocational high school students except for internet use. Interestingly, students with better school performance spent significantly less time in TV viewing, internet usage, and game playing, and therefore had a lower risk of obesity in academic school students. Conclusion: There is a significant relationship between short sleep and obesity that was found only in vocational high school students. The relationship between short sleep and screen time was not significant in Korean high school students.

With the increasing popularity of Smart Grid infrastructure, it is much easier to collect energy usage data using AMI (Advanced Measuring Instrument) from residential housing, buildings and factories. Several researches have been done to improve an energy efficiency by analyzing the collected energy usage data. However, it is not easy to store and analyze the energy data using a traditional relational database management system since the data size grows exponentially with an increasing popularity of Smart grid infrastructure. In this paper, we are proposing a Hadoop based Big data system to store and analyze energy usage data. Based on our limited experiments, Hadoop based energy data analysis is three times faster than that of a relational database management system based approach with the current system.
