Objectives: This study was conducted to investigate the effect of professional self-concept and ethical awareness of dental hygiene (department) students attending a university located in Gwangju and Jeollanam-do on patients' willingness to protect personal information. Methods: Professional self-concept, ethical disposition, and patients' personal information protection intention according to general characteristics were analyzed using t-tests and one-way ANOVA. After confirming the correlation through Pearson's correlation analysis, the effect on the patient's personal information protection intention was confirmed using multiple regression analysis. Results: Professional self-concept, ethical disposition, and the patients' willingness to protect personal information all showed positive correlations. The higher the communication skills of professional self-concept and the higher the idealism of ethical orientation, the higher the patients' willingness to protect personal information. Conclusions: This study, ascertained the effect of dental hygiene students' professional self-concept and ethical consciousness on patients' personal information protection practices. The results suggest that it is necessary to develop an educational program that can enhance the practice of dental hygienists to protect patients' personal information, and to develop and conduct continuous policy development and research.

For dry machining of mineral materials the Institute of Materials Engineering pursues a novel thermal protection shield concept for diamond tools, in which thermal insulating materials in diamond composite structures act as heat shield, which protects diamonds in deeper layers against high temperature and graphitisation. Before the effectiveness of this concept could be investigated suitable composites have to be manufactured. In this paper the powder metallurgical production processes of diamond-alumina-cobalt-composites with varying alumina and cobalt particle sizes, their microstructures and porosities are described. It could be observed that the distribution of small-sized alumina particles ($<70{\mu}m$) in the cobalt matrix is uniform and the porosity of the composite decrease.

Purpose: The purpose of this study was to identify factors influencing patient privacy protection behavior among nursing students and examine the relationships between these factors. Methods: Participants in this study were 144 nursing students who have experienced clinical practice. The data were analyzed using descriptive statistics, one-way ANOVA, Scheffe test, Pearson's correlation coefficient, and multiple regression with IBM SPSS Win 23.0 program. Results: Professional self-concept and ethical values were factors influencing patient privacy protection behavior among nursing students. These variables explained 21.9% of the variance for patient privacy protection behavior. A higher level of patient privacy protection behavior was associated with higher levels of professional self-concept and ethical values. Conclusion: The findings demonstrate that strategies for enhancing patient privacy protection behaviors of nursing students should include methods for forming images of positive nurses and firming ethical values.

In this paper, a protection system using a Multi-Agent concept for power distribution networks is proposed. Every digital over current relay(OCR) is developed as an agent by adding its own intelligence, self-tuning and communication ability. The main advantage of the Multi-Agent concept is that a group of agents work together to achieve a global goal which is beyond the ability of each individual agent. In order to cope with frequent changes in the network operation condition and faults, an OCR agent, suggested in this paper, is able to detect a fault or a change in the network and find its optimal parameters for protection in an autonomous manner considering information of the whole network obtained by communication between other agents. Through this kind of coordination and information exchanges, not only a local but also a global protective scheme is completed. Simulations in a simple distribution network show the effectiveness of the suggested protection system.

Objectives: The school adjustment problems of the adolescence groups become more aggravated and are on the increase. The objective of this study is to identify the causal relationship of intra-family conflicts, self-concept and school adjustment as health protection behavior. Methods: The study setting is the adolescence groups. Data were collected by self-administered questionnaires from the middle and high school students in Seoul. The study sample consisted of 268 students. Structural Equation Modeling(SEM) analysis was conducted to find the causal relationship of intra-family conflicts, self-concept and school adjustment. Results: This study shows that firstly, the total effects of intra-family conflicts have a negative effect on self-concept(path coefficients=-0.080) and school adjustment(path coefficients=-0.107). And the self-concept factor as an intervening variable are affecting positively on school adjustment(path coefficients=0.411). Secondly, the economic conflicts, personaliy conflicts and social activity conflicts of father and mother among various family conflicts are more highly affecting on self-concept and school adjustment(p<0.01) Conclusions: These results imply that first, communication between parents and students is essential to solve the problems of school adjustment. Especially economic conflicts should be solved to improve the self-concept and school adjustment. second, a variety of programs are available for schools to employ in an effort to provide interventions for students who demonstrate school adjustment. Finally, it is necessary for family, school and all the society members to comprehensively cooperate to solve family conflicts and school adjustment.

RFID is an emerging technology and rapidly applied to various industries due to its high-tech characteristic and convenience. Although RFID provides valuable benefits. it might also generate serious privacy problems. Previous studies show that privacy issues should be incorporated in developing RFID systems and more detailed privacy protection methods. However. they just provide basic concept, rough guideline. and simple architecture about RFID privacy protection. Industry needs more structured framework and detailed systematic process to incorporate privacy issues into the RFID system. The purpose of this paper is to develop a framework and detailed process design of RFID privacy protection issues in retail industries. A framework is developed based on individual sensitivity concept, RFID contents, and interface with EPC global standard. Case study is applied to validate the framework and it turns out to be useful. It is expected that the proposed framework and process design would provide more systematic guide lines to solving RFID privacy problems.

Most of the reactor trips in Korean NPPs related to core protection systems were caused not because of proximity of boiling crisis and, consequently, a damage in the core, but due to particular miscalculations or component failures related to the core protection system. The most common core protection system applied in Korean NPPs is the Core Protection Calculator System (CPCS), which is installed in OPR1000 and APR1400 plants. It generates a trip signal to scram the reactor in case of low Departure from Nucleate Boiling Ratio (DNBR) or high Local Power Density (LPD). However, is a reactor trip necessary to protect the core? Or could a fast power reduction be enough to recover the DNBR/LPD without a scram? In order to analyze the online calculation of DNBR/LPD, and the use of fast power reduction as trip avoidance methodology, a concept of CPCS with fast power reduction function was developed in Matlab® Simulink using systems engineering approach. The system was validated with maximum of 0.2% deviation from the reference and the dynamic deviation was maximum of 12.65% for DNBR and 6.72% for LPD during a transient of 16,000 seconds.

원자력발전소 화재방호의 목표는 화재 시 원자로의 안전정지 상태를 유지하여 환경으로의 방사성물질 누출을 최소화하며, 종사자 인명안전 및 재산을 보호하는데 있다. 소방시설은 발생된 화재를 조기 감지 및 진압하여 화재로 인한 피해를 완화시킬 수 있는 심층방어개념에 입각한 중요한 방어수단의 하나이다. 그러나 소방방재청에서 제시하고 있는 소방시설 설치기준이 원자력발전소에 특화되어 있지 않아 인허가 시 별도의 심의 절차가 요구되고 있다. 또한, 성능위주설계와 같은 규정은 작업자의 인구밀도가 비교적 낮은 원자력발전소에 적용하는데 어려움이 있다. 이 논문에서는 원전 화재방호와 관련된 법령의 상세 검토를 통하여 도출된 근본적인 문제점과 KEPIC FPN의 국내 원전 적용성에 대한 평가를 통하여 소방시설에 대한 기술기준에 대한 개선방향을 제시하였다.
