본 발표는 atomic force microscopy (원자력현미경) 기법을 이용하여 그래핀을 포함한 다양한 나노물질의 물리적, 화학적, 역학적, 또한 전기적 특성의 상호영향 (correlation)의 이해를 목표로 한다. 원자력 현미경은 표면과 검침사이의 물리적 힘을 측정하고 이를 피드백시킴으로써 표면의 형상을 얻는 원리이며 표면의 역학적 (마찰력, 점착력), 전기수송적 특성을 동시에 측정할 수 있는 이점이 있다. 또한 원자력 현미경은 표면의 구조적인 특성과 표면에너지에 대한 정보를 나노미터 스케일에서 줄 수 있다. 나노선, 나노입자, 또한 연료전지의 모델 시스템에서 원자력현미경을 이용한 표면의 나노역학적 특성 및 점착력의 측정이 다루어질 것이며 표면공학을 통한 표면처리에 따른 마찰력과 점착력의 제어를 논의할 것이다.

The Korean silk industry is facing challenges due to decreasing demand and intensified competition. To understand its current state and evaluate its competitiveness precisely, we have visited most of the leading silk firms in Jinju area. By questionnaire and in-depth interview, we investigated their operational problems. We found that most of the managers are understanding the necessity of the capabilities in design and material development, but they did not fully aware of the importance of operational flexibilities. Based on the results of the survey, suggestions that are necessary to restore the competitiveness of the Korean silk industry were proposed from industrial and corporate viewpoints.

환경성질환은 19세기 이후 산업화 등으로 인한 특정 물질 등으로 인한 오염이 집중, 심화되면서 그 악영향에 대한 관심 및 중요성이 더욱 커지고 있는 실정이다. 대표적인 환경성질환인 아토피피부염, 알레르기비염, 천식 등 알레르기질환이 지속적으로 증가하는 추세이며, 특히 면역력이 약한 어린이, 청소년 및 노인층을 중심으로 꾸준히 발생하고 있어, 이에 대한 예방관리에 더욱 더 많은 관심을 기울일 필요가 있다.

This was a descriptive study to investigate the effect of social support and health literacy on sick role behaviors in hemodialysis patients. A total of 149 outpatients receiving regular hemodialysis at four dialysis centers located in J city were surveyed. Data were analyzed using descriptive statistics, t-test, one-way ANOVA, Pearson correlation coefficient, and multiple linear regression. Factors including social support (β=.37, p<.001), health literacy (β=.16, p=.035), and religion (others) (β=-.25, p=.001) had an effect on sick role behavior. The explanatory power of model in this study was 22.0%. Therefore, the improvement of sick role behavior in patients undergoing hemodialysis requires specific strategies and interventions that are effective in increasing the social support and health literacy.

시스템이 진화와 노화를 거듭하는 경우 프로그램을 이해하는데 있어서 가장 정확한 문서는 기존의 시스템 자체에서 추출되어진 정보이다. 프로그램의 이해를 돕기 위한 분석기법중의 하나인 프로그램 슬라이싱은 1984년 Weiser에 의해서 소개되어진 이후 다양한 방향으로 연구가 진행되어져 왔다. 특히, 생성되어지는 프로그램 슬라이스가 사이즈가 크고 충분히 집약적이지 못하다는 문제점과 슬라이스의 계산방법이 효율적이지 못하다는 문제점을 극복하기 위하여 여러 가지 방법들을 시도되어 왔다. 본 논문은 고전적인 슬라이싱 기준에 새로운 파라미터를 추가함으로써 제외개념을 이용하여 보다 함수적으로 응집력있고, 사이즈가 작은 슬라이스를 생성하는 선택 슬라이스를 제시하며 이 선택슬라이스를 계산하기 위한 효율적인 방법을 기술한다. 데이터와 제어의 흐름을 이용하여 선택 슬라이싱을 정의하고, 선택 슬라이싱을 위한 종속그래프를 정의하고 이를 사용하여 선형적 시간 내에 선택 슬라이스를 생성하는 알고리즘을 기술한다.

Purpose: This descriptive research study aimed to identify the effect of the health literacy and self-efficacy on the quality of care service of home visitor care workers. Methods: The participants were 124 home visitor care workers who had worked for more than six months at one of the five home-based welfare centers located in D metropolitan city. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and multiple linear regression analysis using the SPSS program. Results: The quality of care service differed significantly by age (F=-1.03, p<.001), career (F=5.09, p=.002), and education status (F=9.57, p<.001). A statistically significant positive relationship was observed between the quality of care service and self-efficacy (r=.63, p<.001). A total of 55.3% of the variance of quality of care service was explained by age and self-efficacy. Conclusion: Based on the results, it is necessary to develop and prepare programs that can increase the self-efficacy of home visitor care workers through a nursing approach to improve the quality of life of elderly.

Purpose: This study develops a health literacy instrument for Alzheimer's disease. Methods: Items were drawn from The Korean version of the Alzheimer's Disease Knowledge Scale (ADKS) and the Korean version of European Health Literacy Survey Questionnaire (HLS-EU-Q47 & HLS-EU-Q16). Content validity was tested by experts. To further refine the questionnaires and test their reliability and validity, data were collected from 324 older adults in the community. Results: Five significant items in the two subscales were derived from the factor analysis. The subscales were named access and understanding. Reliability was good at Cronbach's ⍺ .79, and validity through exploratory factor analysis was KMO .897, p<.001, which was found to be high and significant. Conclusion: The instrument demonstrated high reliability and validity. Therefore, this instrument can contribute to the evaluation of health literacy for Alzheimer's Disease in older adults and to any subsequent intervention, as well as to develop a theory for health literacy for Alzheimer's Disease.

The development of IT technology emphasizes the importance of training IT professionals, and the need for education for elementary and secondary education as well as adult education for training technical talent is expanding. In particular, information curriculum will be added as an essential course from the 2015 revised curriculum, and IT technology will be understood in the curriculum for elementary and secondary schools and will be required to develop applicability to solve problems based on understanding. Currently, research is under way to integrate IT technologies to provide new services, and if the use of personal information is required in the process, thorough security for the leakage of personal information is pre-empted. It also prevents the identification of personal information in the process of transmitting data to the outside world. In this paper, we propose a training method for elementary school subjects to understand the non-identification process that occurs in the process of transferring data using pipe games so that they can understand the principles of non-identification and develop applications to solve real-life problems.

STEAM education is a topic-based curriculum to integrate the concepts into other subjects such as science, technology, engineering, art and mathematics in order to improve the students' interesting, understanding, integrated thinking and problem solving ability. In this paper, we designed STEAM curriculum in the form of Project-based Learning and developed the material for elementary students. We also developed the android-based application through searching for a utilization of IT simulation for enhancement the students' Project-based Learning effect.
