The purpose of this study was to investigate elementary school students' perceptions about science, engineering and technology and their images of scientists, engineers, and technicians. In order to investigate students' images of scientists, engineers, technicians and student's perception of science, engineering, and technology, we used the tools "Draw a scientist at work, Draw an engineer at work, and Draw a technician at work". We have revised the tool DAST (Draw a scientist test), which was used in Fralick et al.'s study (2009). Subjects were 209 6th grade students sampled from an elementary school in G-city in Korea. According to the results of this study, the students' representative image of a scientist was similar to stereotypical scientist image in previous studies, but the students perceived science as a field of research with various professionals. The students' representative image of an engineer was a man with short hair, no beard or mustache, wearing ordinary clothes but no glasses. The engineer was designing or constructing a ship, a robot, a computer, and an airplane. The students' representative image of a technician was a man with short hair, wearing protective goggles and a mask for welding. The technician was fixing a car, a robot, a rocket, etc. and working with wrenches, hammers, screw drivers, welding machines, etc. Many students didn't perceive engineering and technology as fields of research. Also, many students didn't variously perceive engineering and technology as fields and ways of study.

This study has been conducted to investigate the effect of self awareness of halitosis on the quality of life related to oral health in patients with chronic renal failure undergoing hemodialysis and use basic data related to oral health of patients with chronic renal failure which is very rare in Korea. In terms of oral symptoms based on awareness of halitosis, there were significant differences in symptoms of teeth pain in the past one month, bleeding gums, symptoms of tongue or cheek pain, dry mouth, In terms of status of oral functions, there were significant differences in discomfort upon chewing foods, difficulty of pronunciation and presence of lost teeth. As the results of analysis of effect of self awareness of halitosis on the quality of life related to oral health in patients with chronic renal failure, it was shown that there were significant effects in psychological discomfort(B=-2.028, p<.01), poor social skills(B=2.596, p<.01) and social disadvantage(B=-2.173, p<.01). Thus, because self awareness of halitosis gives psychologically and socially negative effects, it could be an important factor to patients with renal failure whose number is rapidly increasing.

실내에서 작업자의 위치 정보를 취득하면 사용자의 이동 경로 파악이나 물체의 지역화 및 상황인지 서비스가 가능하다. 최근, BLE(Bluetooth Low Energy) 비콘을 사용하여 작업자의 실내 위치를 파악할 수 있는 여러 가지 연구가 진행되고 있으나 BLE 비콘의 신호세기 강도와 RSSI(Received signal strength indication)의 정확도에 대한 에러율 증가로 인해 실내 작업자 위치 파악 연구에 어려움이 있다. 본 연구에서는 BLE 비콘에서 취득한 RSSI 정보에 대해 PCA, ICA, SVM의 패턴인식 알고리즘을 적용하여 인식정확도를 구하고, 여러 패턴인식 알고리즘 중에서 어떤 알고리즘이 인식정확도 측면에서 적용이 가능한지 제시하였다.

This study explored the effect of ASR-based pronunciation instruction, using a mobile platform, on EFL learners' pronunciation development. Particularly, this quasi-experimental study focused on whether using mobile ASR, which provides voice-to-text feedback, can enhance the perception and production of target English consonants minimal pairs (V-B, R-L, and G-Z) of Korean EFL learners. Three intact classes of 117 Korean university students were assigned to three groups: a) ASR Group: ASR-based pronunciation instruction providing textual feedback by the mobile ASR; b) Conventional Group: conventional face-to-face pronunciation instruction providing individual oral feedback by the instructor; and the c) Hybrid Group: ASR-based pronunciation instruction plus conventional pronunciation instruction. The ANCOVA results showed that the adjusted mean score for pronunciation production post-test on the Hybrid instruction group (M=82.71, SD =3.3) was significantly higher than the Conventional group (M=62.6, SD =4.05) (p<.05).

This study examines degree of fairness migrant workers in Korea feel with their wages in comparison to those of their homeland and Korean workers who do the same job in Korea as theirs, and what factors affect the feelings. For the study, 742 migrant workers from China, Vietnam, Philippines, and Indonesia employed by manufacturing firms in Seoul and Gyenggi areas were surveyed. The results show that most migrant workers in Korea feel unfair about their wages, and the feeling of unfairness appears more strongly when comparing with the Korean workers than with their homeland workers. The effectiveness of variables affecting fairness also varies according to the object of comparison: in comparison to homeland workers, age, sex, monthly income before migration, money spent for employment, and satisfaction with working conditions are significant: in comparison to Korean workers, ethnicity, sex, legal status, satisfaction with working conditions are significant.

The purpose of this study was to suggest measures to improve safety and health training by analyzing trainees who participated in the training programs. A survey was administered to 226 trainees who participated in and completed the safety and health training programs provided by the Korea Occupational Safety and Health Agency. The study results showed that the level of satisfaction of employers for the training programs was the lowest compared to the middle managers and employees. Moreover, the middle managers' job competencies were increased, and they applied newly acquired knowledge and skills to their jobs. However, there were significant differences between industries. Finally, although all levels of trainee agreed on the effectiveness of safety and health training, the perceptions of employers were lower than those of employees. Based on these study results, several implications to improve the safety and health training were suggested.

In this study, we examined the influence of news frame and involvement on risk perception. Based on individuals' optimistic bias in risk judgement and the third-person effect theory, we developed research hypotheses. An experiment was conducted in which 243 undergraduate and graduate students participated. Results indicated that societal level risk judgements were relatively invariant across experimental conditions but personal level risk judgements were influenced by the news frame and individuals' involvement in irradiated food. Based on the results, we provide explanations concerning when and how optimistic bias takes place in each experimental condition.

This article is concerned with the values of the BICOF in terms of the urban revitalization. The values of the BICOF cover the economic value, social value, cultural value and city image value. The 13 indicators for measuring the values of the BICOF are developed. The article examined how the related stakeholders identified the BICOF's values on the Bucheon City by using AHP method. In addition, the objectives and programmes of the BICOF are analyzed in the perspective of the urban revitalization. As a result, the recognition of the BICOF's values varied according to the stakeholders. In addition, the result of AHP analysis indicates that the cultural values and image values should have priorities in comparison with the social values and economic values. This recognitions is different from the recent formal statements that BICOF's economic values should be emphasized as a priority. The article concludes that the identity of the BICOF should be established in the base of building the value consensus among the related stakeholders.
