Background and Objectives: This study aimed to investigate the occupational performance of Korean workers with and without hearing loss and analyze the hearing-related difficulties in the working environment. Subjects and Methods: The Amsterdam checklist for hearing and work was used for the analyses and the occupational environments of the Korean workers were investigated. Out of 129 total participants, 86 workers experienced severe to profound hearing loss and 43 had the normal hearing ability. The hearing-impaired workers were recruited from two leading vocational centers and normal-hearing workers were their colleagues. Results: The hearing-impaired workers were found to take fewer sick leaves and exhibited higher rates of permanent job statuses compared to the normal-hearing workers. Workers with hearing loss rarely detected background sound; however, they could perceive reverberation more frequently. They felt more satisfied with their careers than the normal hearing workers as they received social support and needed to put their effort into hearing for most hearing activities. Furthermore, the effort in hearing increased with the increase in job demand, job control, social support, and career satisfaction. The working hours per week increased with the increase in age, education level, job demand, job control, and social support. Different trends were observed in 9 out of 12 variables while comparing the data from the present study with that obtained from the hearing-impaired workers of the Netherlands, indicating a large difference between countries. Conclusions: Although the hearing-impaired Korean workers operate diligently with good job positions, it is necessary to enhance their acoustic environment and provide them social support. Considering the cultural background of the hearing-impaired workers, the development of suitable vocational rehabilitation programs and specific questionnaires is strongly recommended worldwide.

Purpose : With a view to providing basic data to develop basic cardiopulmonary resuscitation education suitable for female college students, the basic cardiopulmonary resuscitation education was conducted to grasp students' knowledge, skill accuracy and the attitude change before and after the education. Methods : Convenience sampling was made on first graders(total-38 students) of K college located in K city, Chungcheongnam-do, and this was a preliminary research designed before and after choosing a single group. In terms of methods, the researchers as specified ; 1) Handed out questionnaires to students directly to make them fill in firsthand and collected the questionnaires. 2) Utilized Power Point materials based on 2005 AHA guideline and used Anne/Skill Reporter$^{(R)}$ torso produced by Leardal Inc, and Little Anne$^{(R)}$ to conduct practical education individually. 3) Asked students to give Anne/Skill Reporter$^{(R)}$ torso basic cardiopulmonary resuscitation five times with the ratio of 30:2, and then one of researchers filled in the evaluation sheet individually. 4) Evaluated the accuracy of students' ability to perform the resuscitation based on the record of Anne/Skill Reporter$^{(R)}$ integrated printer(which was the objective tool to grasp students' skills accuracy). 5) Gave out questionnaires to make students fill them in and then collected them, after completing the practical evaluation. Results : 1) In case of the attitude(confidence) about basic cardiopulmonary resuscitation, students' confidency rose from 14%(before the education) to 55.5%(after the education)- which was a positive change. 2) In case of the attitude(educational necessity) about basic cardiopulmonary resuscitation, students' confidency rose from 94.7%(before the education) to 100%(after the education)- which was a positive change. 3) As a result of the education, some female college students' scored knowledge about basic cardiopulmonary resuscitation. The average point also reached 88.95%(after the education), jump from 63.51%(before the education), which was the rise of 25.44%. 4) Regarding skill accuracy, pressure accuracy(%)($M{\pm}SD=91.37{\pm}14.16$) was higher than respiration accuracy(%)($M{\pm}SD=61.55{\pm}26.13$). Conclusion : The result showed that students' attitude(confidence, on basic cardiopulmonary resuscitation changed positively, and meaningful difference(p= .000) existed in the change of students' knowledge. Anne/Skill Reporter$^{(R)}$ performance showed that the accuracy of mouth-to-mouth resuscitation was lower than that of chest compression.

Background: The risk of malignancy index (RMI) for the evaluation of adnexal masses is a sensitive tool in certain populations. The best cut off value for RMI 1, 2 and 3 is 200. The cut off value of RMI-4 to differentiate benign from malignant lesions is 450. Our aim was to evaluate the efficiency of four different malignancy indexes (RMI1-4) in a homogeneous population. Materials and Methods: We evaluated a total of 153 non-pregnant women with adnexal masses who did not have a history of malignancy and who were above 18 years of age. Results: A cut-off value of 250 for RMI-1 provided 95.9% inter-observer agreement, yielding 95.9% specificity, 93.5% negative predictive value, 75.0% sensitivity and 82.8% positive predictive value. A cut-off value of 250 for RMI-1 showed high performance in preoperative diagnosis of invasive malignant lesions than cut-off value of 200 in our population. A cut-off value of 350 for RMI-2 provided 94.5% inter-observed agreement, yielding 94.2% specificity, 93.4% negative predictive value, 75.0% sensitivity and 77.4% positive predictive value. RMI-2 showed the higher performance when the cut-off value was set at 350 in our population. A cut-off value of 250 provided 95.2% inter-observer agreement, yielding 95.0% specificity, 93.2% negative predictive value, 75.0% sensitivity, and 88.0% positive predictive value. RMI-3 showed the highest performance to diagnose malignant adnexal masses when the cut-off value was set at 250. In our study, RMI-4 showed similar statistical performance when the cut-off value was set at 400 [(Kappa: 0.684/p=0.000), yielding 93.8% inter-observer agreement, 93.4% specificity, 93.4% negative predictive value, 75.0% sensitivity, and 75.0% negative predictive value]. Conclusions: We showed successful utilization of RMIs in preoperative differentiation of benign from malignant masses. Many studies conducted in Asian and Pacific countries have reported different cut-off values as was the case in our study. We think that it is difficult to determine universally accepted cut-off values for RMIs for common use around the globe.

This study analyzed the relationship between self-directedness of science-gifted elementary students and their expression of scientific creativity in science-gifted class. A science-gifted program on the topic of Hydraulic Machine was implemented to 34 fifth-graders in the Science-Gifted Education Center of an education office in Seoul, Korea for four weeks. The self-directedness of the gifted students was divided into three types of 'General, Scientific, and Topic-Related Self-Directedness'. The products of the students' activities were assessed by using a scientific creativity assessment formula. Qualitative research, such as analysis of observations and interviews, was also conducted in order to identify characteristics that were not apparently revealed by quantitative data. The main results of this study are as follows: First, science-gifted elementary students' general self-directedness and their scientific creativity were significantly correlated (r=.373). Second, the students' scientific self-directedness and scientific creativity did not have a significant correlation (r=.294). Third, there was a positive correlation between the students' topic-related self-directedness and their expression of scientific creativity. Their self-rated scores (r=.420) for the topic-related self-directedness and the number of activity types associated with the topic had a positive correlation (r=.350). Fourth, the students were categorized into four groups according to the levels of their self-directedness and scientific creativity, and the result showed that Type HH (high self-directedness and high scientific creativity) was the most common type (15 students, 38.5%), followed by Type LL (low self-directedness and low scientific creativity) (11 students, 28.2%). Eight (20.5%) and five students (12.8 %) belonged to Type LH (low self-directedness and high scientific creativity) and Type HL (high self-directedness and low scientific creativity) respectively. Fifth, the classroom observation of the students in groups revealed that groups with more number of Type HH demonstrated better cooperation and performance. Sixth, the analysis results of the observation were almost matched to the results of the self-directedness and scientific creativity tests. The students with higher self-directedness demonstrated active class participation and good cooperative skills. The students with higher scientific creativity had a tendency to generate creative ideas more frequently in given situations. Seventh, dynamic activities were perceived as enjoyable and exciting by 76.9% of the students, but static activities that require creativity were regarded as interesting only by 23.1% of the students. Among the students who were satisfied with both the creative and static activities, Type HH accounted for the largest proportion (55.6%). In conclusion, factors such as students' interests, initiatives, and attitudes displayed through voluntary participations originated from their own daily life can predict the degree of scientific creativity associated with the topic. Also, when students were categorized into four types according to the level of self-directedness and scientific creativity, there was a tendency of active behavior in class, cooperative skill, and activity satisfaction. This suggested that we should consider self-directedness and scientific creativity in selecting the gifted, grouping them in class, and designing and executing programs for science-gifted elementary students.

It is important how the leader leads the organizational members with leadership appropriate to environment changes as the leader has great influence on the management of hospital organization. These data were collected from the questionnaire surveyed, from February 14 through February 28, 2003, to 218 people among those in the field of doctorship, management administration, nursing, technology, medical engineering, management engineering, and general affairs, working for three hospitals under S medical foundation in Pusan. The principal findings of this research are as below : 1. Type of leadership and job satisfaction had positive correlation in terms of both transformational and transactional leadership, with former having more relation than the latter. 2. Type of leadership and organizational commitment had positive correlation in terms of intellectual stimulus and situational rewards, having little relation statistically. 3. Type of leadership and turnover intentions had negative correlation only in individual consideration, situational rewards, and exceptional management, showing that transactional leadership had more relation than transformational leadership. 4. In terms of leadership and its effect on the organizational performance and turnover intentions, transformational leadership had more correlation than transactional leadership. But transactional leadership also turned out to have effect on organizational performance. When transformational leadership used, turnover intentions were lower than when transactional leadership used. However, both transformational and transactional leadership had negative correlation to turnover intentions. 5. Effect that type of leadership according to job classification, status, age, and academic career has on organizational performance and turnover intentions was differed by those factors; especially, in the occupation of doctor, both transformational and transactional leadership had positive correlation to turnover intentions. 6. Regression analysis on the factors of organizational performance and turnover intentions showed that higher age had positive correlation to the organizational performance in terms of socio-demographical features and that the more leadership was used for charismatic and situational rewards and the less leadership was used for intellectual stimuli, the higher organizational performance was likely. In short, hospital operators and managers should examine each manager's qualification, type, and style of leadership in the hospital organization, and they must develop lasting programs for effective education and training for developing characteristics of leadership are in needed to have managers with appropriate managerial mind to respective post and status. It should be kept in mind that manager's leadership especially has great effect on members' goal-setting, goal-achievement, organizational performance, and turnover intentions as it is a decisive factor of organizational members' attitude and motivation.

BK21사업은 장기간 막대한 예산이 투입되는 국가주도의 고등교육사업이다. 사업의 효과성을 평가한 선행연구는 선정된 사업단(팀)들 전체를 대상으로 실적 중심의 양적 성과에 초점을 맞춘 경우가 많고, 사업에 참여한 대학원생에 관한 선행연구는 만족도 조사에 그친 경우가 많아 사업단별 혹은 학술 분야별로 BK21사업이 대학원생의 수행, 역량, 만족 등에 미치는 영향을 깊이 있게 다룬 연구는 많지 않았다. 본 연구는 3단계 BK21플러스 사업에 선정된 1개 학과 단위의 단일 사업단을 대상으로 2013년부터 2019년까지 수집된 대학원생 수행에 대한 정량 자료(예: 게재논문 수)와 제3자 평가 자료(예: 대학원생 수행평가) 그리고 설문 자료(예: 교육환경 만족도)를 활용해 BK21플러스 사업참여의 효과와 시간의 흐름에 따른 대학원생 역량 변화 정도를 조사하였다. 그 결과 사업에 참여한 학생이 미참여 학생보다 논문실적이 더 많았고, 연구능력과 전반적인 수행수준 평가에서 더 높은 점수를 받은 것으로 나타났다. 사업단의 교육, 연구, 국제화 인프라에 대한 대학원생의 만족도 역시 높은 것으로 나타나 BK21사업 수혜의 직간접적 긍정 효과를 확인할 수 있었다. 본 연구는 단일 사회과학 사업단에 초점을 맞춰 BK21 교육지원사업의 효과를 다양한 자료를 활용해 검증함으로써 개별 사업단의 운영 성과에 대한 경험적인 평가를 시도하였다는 점에서 의의가 있다.
