In this study, the model cognition level of high school science-gifted students about the two types of acid-base models taught in secondary schools was analyzed. In order to find out the model cognition level of students, 12 items were developed based on the acid-base reaction and the dissociation reaction of acids and bases. The subjects of the study were 95 students of two science-gifted schools. As a result of the questionnaire analysis, model cognition levels were analyzed 6 levels in the context of consistency, inconsistency, and unexplainable scope of the two models. In the acid-base reaction item, the largest percentage of students cognized only understanding of the two models. In the acid-base dissociation reaction item, they understood the two models and perceived the 'Known Ignorance' that cognizes the limitations of one model. However, there was only one student who perceived the limitations of both models and all of the 'Unknown Ignorance' that the model could not explain. Through this, we argued that there is a need for educational efforts to raise the model cognition level of science-gifted students.

The purpose of this study is to measure the expectation level and perception level of service quality in 25 records centers in local governments based in Seoul. For this, an evaluation index consisting of 5 factors and 31 items is developed through literature research and an investigation of the present condition. The results of this study confirmed that users are not satisfied with the service quality of the records centers in the local governments as the expectation level is higher than the perception level, with a statistically significant difference. This study can be substantial in attempts to analyze the present status of the service quality of the records centers in local governments and in proposing an improvement plan based on the process quality.

The purpose of this study was to identify the factors influencing sexual consciousness, gender egalitarianism and awareness levels of sexual harassment among college students. Methods: As a descriptive, correlative study, the data was collected from 274 college students. The copies of the questionnaire were collected from April 23 to 30, 2015. The data was analyzed using a t-test, ANOVA, Pearson correlation coefficients and multiple linear regression. Results: Sexual consciousness, gender egalitarianism and sexual harassment awareness levels averaged 3.00 (range of score 1-5), 1.97(1-4) and 4.09 (1-5), respectively. Awareness levels of sexual harassment had a positive correlation with sexual consciousness, and a negative correlation with gender, major field of study, living patterns, and gender egalitarianism. Conclusion: This study has identified sexual consciousness and gender egalitarianism, as well as the associated influencing factors, among college students. The results of this study are expected to be used as basic data for developing strategies and programs for the prevention of sexual harassment among college students.

This research is accomplished for the purpose of providing fundamental materials to improve the level of prevention consciousness by deducting awareness difference through analyzing awareness level about terror preparation of members of crisis management system - the public service personnel in charge of crisis management in a self-governing body and the fire fighting public service personnel. For this research, That is measured through the priority order survey about a specialty of public service personnel in charge of crisis management and a level of crisis prepartion and a cooperation between crisis management system and etc. As a result of analysis, it is revealed that there is a difference about the priority order of measurement variable to terror preparation but all the members are recognizing the importance of that.

네트워트를 이용한 비대면 거래의 활성화와 국경을 넘는 다양한 인적 교류로 인해서 개인의 신원을 증명하는 사회적 기술적 수요가 나날이 급증하고 있으며, 더욱이 핀테크의 활성화와 국제적으로 벌어지고 있는 테러 등의 위협 등은 개인의 신체적 특징에 기반을 둔 바이오인식 기술의 발달을 촉진 시키는 계기가 되었다. 바이오인식 기술은 전자여권의 예와 같이 국가간에 바이오인식 정보를 활발하게 주고 받아야 하는 상황이고, 더욱이 개인의 신체적 특징정보를 취득하여 등록하는 국가와 국경통제 등을 위하여 개인의 바이오인식 정보 등을 취득하여 인증하는 국가가 상이한 경우가 대부분이다. 따라서, 바이오인식 정보간의 호환성을 유지하기 위한 표준과 이를 평가하기 위한 표준적합성 평가기술, 일정 수준의 보안강도를 유지하기 위한 표준화된 성능 평가 절차와 보증 수준, 바이오인식 정보를 응용한 개인인증 기술, 프라이버시와 밀접하게 연관 되어 있는 바이오인식 정보의 보호를 위한 표준 등이 다양하게 수행되어 왔다. 본 논문에서는 이러한 바이오인식 표준화를 위한 국외 표준화 기구를 소개하고, 각 기구별 표준화 현황을 살펴본다.

In speech recognition, confidence measuring is to decide whether it can be accepted as the recognized results or not. The confidence is measured by integrating frames into phone and word level. In case of word recognition, the confidence measuring verifies the results of recognition and Out-Of-Vocabulary (OOV). Therefore, the post-processing could improve the performance of recognizer without accepting it as a recognition error. In this paper, we measure the confidence modifying log likelihood ratio (LLR) which was the previous confidence measuring. It accumulates only those which the log likelihood ratio is negative when integrating the confidence to phone level from frame level. When comparing the verification performance for the results of word recognizer with the previous method, the FAR (False Acceptance Ratio) is decreased about 3.49% for the OOV and 15.25% for the recognition error when CAR (Correct Acceptance Ratio) is about 90%.

소비자의 욕구와 개성화, 그리고 시장경쟁력에서 생산체제가 변화되면서 기업들의 물류환경여건도 변화를 가져와 물류가 기업들에게 당면한 주요 과제가 되었다. 사회 간접자본의 부족으로 인한 도로, 항만 등의 정체현상이 심화되고 3D업종에 속하는 물류부문은 더욱 인력난을 겪게 되면서 물류비상승이라는 부담을 안게 되었다. 그리고, 컴퓨터, 정보통신기술 등과 같은 첨단의 기술혁신이 이루어 집에 따라 컴퓨터 및 각종 기기들의 연결이 가능해지면서 물류정보시스템 구축이 활발하게 이루어져 가고 있다. 그러나, 이러한 현실에도 불구하고 기업들은 이에 대한 효율적인 대처 방안을 마련하지 못하고 물류에 대한 인식조차 못하고 있거나 잘못 이해하고 있는 실정이다. 본 논문은 이러한 문제점을 인식하여 물류정보시스템의 활용수준과 물류활동 연계 그리고 물류전략에 대한 이론을 정립하고 이를 근거하여 나라 기업률이 물류를 어떻게 인식하고 있는가를 물류정보시스템의 활용수준, 물류활동연계, 물류전략 등의 변수를 도입, 측정하여 봄으로써 우리나라 기업의 물류에 대한 문제점들을 규명하고 앞으로 물류의 능률적인 실시를 위한 올바른 방향을 제시하는데 그 목적을 두고 있다. 실종분석 결과 물류성과에 대한 물류정보시스템 활용수준과 물류연계수준은 물류성과에 영향을 미치는 것으로 나타났다. 그리고, 물류 기능별 정보시스템 활용수준과 물류차별화 전략이 물류성과에 상호작용 효과를 보이는 지를 알아본 결과 상호작용효과가 있는 것으로 나타났다.

This study aims to examine care workers' role perceptions of their occupation and job satisfaction with their work. They are core human resources in elderly care work practices and their perceptions of their occupation are likely to affect their work performance and job satisfaction. A mail survey is conducted targeting to 400 care workers who are at work in long-term care facilities located in Seoul, Gyeonggi and Pusan. Research findings are as follows: firstly, the perception level of care workers' professionalism is 3.38, and job satisfaction is 3.41. Secondly, the correlation analysis between perception level of professionalism and job satisfaction, coefficient is .553, which shows positive relations between two variables. Thirdly, the study shows that care workers' perceptions of professionalism significantly affects their job satisfaction. This study concludes that it is necessary to take a variety of measures in contribution to improve the quality of service through reinforcement of perception of professionalism higher than present level of care workers who supply direct service in long-term care facilities.
