  • The purpose of the survey is to identify possible new areas of research relating to nanotechnology and in particular areas in which the established facilities of the Centre for Metrology can be employed to good effect. This survey indicates that nanotechnology, a sub set of the more embracing Nano Science, is a rapidly developing discipline with good potential for Electronic and Mechanical Engineering. Nanotechnology includes three areas: Nanometrology, Nanometer positioning and Control, and Nanomanufacturing. In each of the areas, the current research situation and developing trends have been summarised. Possibilities for future work indicated.

  • This study aims to determine the changes in health beliefs and practices of dental hygienists on infection control after having received special training on that subject. The study population consisted of dental hygienists working at the dental institutions located in Seoul and Gyeonggi areas. The intervention group and the control group each had randomly assigned 26 dental hygienists. The intervention group received training courses on infection control once a week for 3 hours, for a total of 4 training sessions. We used a survey tool to find the changes between the two groups regarding their health beliefs and practices on infection control measures. The survey was conducted prior to the training sessions, 3 months and 2 weeks after the training. The study results revealed statistically significant increases in perceived sensitivity, perceived seriousness, and perceived benefits after the training courses in the intervention group (p<0.05). A statistically significant decrease in perceived barriers was also noted in the intervention group (p<0.05). Additionally, there was a statistically significant increase in the practice of infection control in the intervention group as compared to the control group (p<0.05). Therefore, we conclude that infection control training is crucial in bringing about positive changes to the health beliefs of dental hygienists, and a structured system is necessary for continuous infection management along with training in order to improve infection control practices.

  • This study explores the role of the Accounting Information System (AIS) in mediating the relationship between internal control and the performance of employees. This study examines whether internal control would influence the performance of employees and whether the AIS would impact the performance of employees in Jordan's industrial small and medium-sized enterprises (SMEs). Internal control is expected to impact employee performance. The survey questionnaire was used to gather data. A random sampling approach was used to survey the respondents. A total of 270 questionnaires were distributed; only 203, with a 75% response rate, were available. The data was analyzed using AMOS and SPSS. The result from the analyses provides support for the hypothesis that AIS mediates the relationship between internal control and the performance of the employee. Specifically, this study found evidence that internal control yielded a strong positive relationship with employee performance and a positive relationship with AIS. The study also found that AIS had a positive relationship with the performance of the employee. In brief, internal control has major effects on employee performance. Also, the AIS mediates the relationship between internal control and the performance of the employee. The result of this research found that in the relationship between internal control and employee performance, AIS plays an important role.

  • Purpose: The purpose of this study was to identify the current status of the awareness and practice of breast self-examination (BSE) among Korean women. Materials and Methods: The study population was derived from the 2007 Korea National Cancer Screening Survey (KNCSS), an annual cross-sectional survey that uses a nationally representative random sample to investigate cancer-screening rates and related factors. A total of 1,255 Korean women aged ${\geq}30$ years participated in this study. Results: Of all participants, 88.0% reported that they had heard of BSE. The most common source of information on BSE was the media such as TV, radio and newspapers (87.0%). Recommendations from medical staff reached only 17.2%. The overall proportions of regular and irregular BSE were 13.2% and 16.1%, respectively. The main reason for not performing BSE was lack of knowledge about how to conduct the exam (31.7%). Conclusion: Despite a high level of awareness about BSE, only a small minority of women examine their breasts regularly in Korea.

  • The purpose of this study was to evaluate weight control program provided by university health care center for female college students. The program was 8-week long and composed of diet, exercise, and behavioral modification. Evaluation was made on the completion of 8-week program and a follow-up survey was done at 3-24 months after the end of program by telephone or bye-mail. Total of 76 women completed the 8-week program and 51 for follow-up survey. On the completion of 8-week program, significant decreases in body weight, BMI, body fat (kg), % body fat, and WHR were resulted, however, no change in muscle mass was found. Even the subjects without weight change showed significant reduction in body fat (kg) and % body fat. Total food intake was decreased resulting in reduced intakes of most nutrients. Meal distribution of energy was changed; %energy from snack decreased from 22% to 14%, and proportion for breakfast increased. Blood values of hemoglobin, hematocrit, total cholesterol, HDL-cholesterol, LDL-cholesterol, and triglyceride were within normal range, and no changes were observed by this program. The follow-up survey revealed that 88.3% of the subjects continued to lose weight after completion of the program, while only 7.8% gained weight. And 78.4% of the subjects considered the program effective. In conclusion, the weight reducing regime with education is effective for long lasting weight control and health conscious behavior for female college student. Since the subjects reduced the size of meal, instead of cutting only calories down, food selection to meet all the nutrient requirements except energy should be emphasized.

  • Objectives: This study was conducted to determine factors related to glycemic control among Korean patients with diabetes. Methods: Data was collected from the Fourth (2007-2009) Korea National Health and Nutrition Examination Survey (KNHANES) which was a nationwide, cross-sectional survey. The study participants who are available for hemoglobin A1c (HbA1c) were 1,441 patients with diabetes aged 30 years and older. Poor glycemic control was defined as $HbA1c{\geq}7.0%$. Data were analysed using logistic regression. Results: The proportion of patients with the poor glycemic control ($HbA1c{\geq}7.0%$) was 49.5%. After adjusting for confounding factors, younger aged persons (30-49 years) were less likely to control the blood glucose than older aged persons (60-69 years) (Adjusted OR=0.533, 95% CI [0.295-0.960]) and longer duration of diabetes was positively related to poor glycemic control (Adjusted OR=2.018, 95% CI [1.418-2.873]). Conclusions: Age and duration of diabetes were significantly related to blood glucose control. Therefore, considering these factors is helpful for developing a strategy to improve blood glucose control in diabetes.

  • Freshwater fish intake is a critical parameter for deriving water quality criteria and water quality standards for protection of human health based on human health risk assessment. Although the freshwater fish intake parameter should be accurate and representative of Korean fish consumption for the water quality criteria to be reliable, data are limited in Korea and have low reliability. In this study, Korean National Health and Nutrition Examination Survey data from 2008-2010 were analyzed to reevaluate freshwater fish consumption. Based on these results, an average consumption rate of 3.0 g/day per person, a $90^{th}$ percentile consumption rate of 0.0 g/day per person, an average consumption rate of 65.7 g/day per fish consumer, and a $90^{th}$ percentile consumption rate of 153.4 g/day per fish consumer were proposed for derivation of water quality criteria using a conservative approach and various exposure scenarios.
