Background and Objectives: Non-linear frequency compression (NLFC) technology compresses and shifts higher frequencies into a lower frequency area that has better residual hearing. Because consonants are uttered in the high-frequency area, NLFC could provide better speech understanding. The aim of this study was to investigate the clinical effectiveness of NLFC technology on the perception of speech and music in patients with high-frequency hearing loss. Subjects and Methods: Twelve participants with high-frequency hearing loss were tested in a counter-balanced order, and had two weeks of daily experience with NLFC set on/off prior to testing. Performance was repeatedly evaluated with consonant tests in quiet and noise environments, speech perception in noise, music perception and acceptableness of sound quality rating tasks. Additionally, two questionnaires (the Abbreviated Profile of Hearing Aid Benefit and the Korean version of the International Outcome Inventory-Hearing Aids) were administered. Results: Consonant and speech perception improved with hearing aids (NLFC on/off conditions), but there was no significant difference between NLFC on and off states. Music perception performances revealed no notable difference among unaided and NLFC on and off states. The benefits and satisfaction ratings between NLFC on and off conditions were also not significantly different, based on questionnaires, however great individual variability preferences were noted. Conclusions: Speech perception as well as music perception both in quiet and noise environments was similar between NLFC on and off states, indicating that real world benefits from NLFC technology may be limited in Korean adult hearing aid users.

본 논문은 화물자동차 회사와 위수탁차주의 위수탁제에 대한 인식 차이를 확인하고, 인식차의 개선이 시급히 이뤄져야 할 인자를 도출, 이를 기반으로 한 경영모델 수립의 근거를 제시하였다. 위수탁차주의 인식 차이에 기반한 경영모델을 설정하고, 연구 가설을 설정하여 신뢰성과 타당성 및 확인적 요인분석 및 경로분석과 매개효과 검증을 실시하였다. 분석결과 58개의 설문 문항 중 화물자동차 회사와 위수탁 차주의 위수탁제에 대한 인식 차이가 나타난 항목은 전체 65개 문항 중 56개의 문항이고, 해당 문항을 경영 모델 인자로 투입, 분석자료는 위수탁차주의 인식 자료만을 사용하여 확인적 요인 분석과 경로분석과 매개효과 검증을 실시한 결과, 5개의 가설이 채택되었고, 인자가 매개효과는 없는 것으로 분석되었다. 보상체계의 적절성이 상호간의 관계 개선에 영향을 주고 상호간의 관계 개선이 운송서비스의 개선으로 연결되고 있다고 분석할 수 있다. 다만, 매개효과는 크지 않아서 기각되었기 때문에 이 효과를 과장해서 판단하지는 않아야 한다.

Objectives : This study was conducted during the period from August 30 to September 9, 2011 in order to survey difference in the general perception of medical market opening and factors related to the choice of foreign hospitals among dental hygiene and nursing students at universities in Seoul. Methods : For this purpose, 438 students were surveyed using a questionnaire and collected data were analyzed using SPSSWIN 18.0. Conclusions drawn from this study are as follows. Results : 1. With regard to dental hygiene and nursing students' perception of medical market opening according to general characteristics, significant difference was not observed according to gender, experience in working at a hospital, medical institution used, and the frequency of using medical institutions, but significant difference was observed according to department, and interest in healthcare-related news. 2. There was significant difference in dental hygiene and nursing students'pro/con attitude toward medical market opening, but not in gender, experience in working at a hospital, medical institution used, and the frequency of using medical institutions. 3. With regard to intention to visit and revisit foreign hospitals, there was significant difference between dental hygiene and nursing students in intention to visit but not in intention to revisit. Conclusions : The results of this study suggest that more research on the medical market opening portion dental hygiene and nursing students' perception and attitude did not differ significantly, so the more accurate and open markets for a variety of medical education and school education and a variety of materials through hands-on experience be grasped should allow. Furthermore, students' acquisition of accurate prior knowledge about medical market opening is expected to be helpful to activate their employment in overseas.

본 연구는 치위생(학)과 학생들의 성격유형에 따른 생명윤리의식을 조사함으로써 학생들이 생명윤리에 대해 관심과 책임을 갖도록 계기를 마련하고자 치위생(학)과 학생 519명을 대상으로 자가기입법에 의한 설문조사를 실시하였다. SPSS 12.0을 이용하여 분석한 결과 다음과 같은 결론을 얻었다. 1. 일반적 특성에 따른 성격유형을 알아본 결과 성별에 따라 친화성이 유의하였고, 연령과 학년별, 임상실습경험 유무에 따라 성실성에 유의한 차이가 있었다. 경제적 상태에 있어서는 신경증, 외향성, 성실성, 개방성이 유의한 것으로 보이나 집단 간 분산의 동질성 가정을 충족하지 못하였다. 2. 일반적 특성에 따른 생명윤리의식을 비교분석한 결과 성별에 따라 태아생명권이 유의하였으며(p<0.001), 연령에 따라서는 인공수정이 차이가 있었다. 학년별, 임상실습 경험 유무에 따라 신생아생명권에, 종교에 따라서 인공임신중절에 유의한 차이를 보였다. 3. 성격유형과 생명윤리의식에 관한 변수의 상관성은 외향성과 신생아생명권만 0.119의 미약한 상관성을 보였다. 4. 생명윤리의식에 영향을 미치는 성격유형의 변수는 성격이 외향성일수록 태아진단과 신생아생명권에 영향을 주는 변수로 나타났다. 이상의 결과로 볼 때 5가지 성격유형이 학생들의 생명윤리의식과 관련된 모든 정보를 제공할 수는 없겠지만 영향을 주는 일부 요인이 될 수 있다는 것을 알 수 있었다.

Purpose - This study aims to exploratorily analyze relationship among pressure on business failure, social safety net perception, and entrepreneurial intention targeting potential business founders - pre-entrepreneurs and re-entrepreneurs. Research design, data, and methodology - Out of 450 collected surveys, 386 were used for analysis. Among these, 216 were from pre-entrepreneurs and 170 were from re-entrepreneurs. Frequency analysis, reliability and validity analysis, and regression analysis were performed. Results - In analysis of pre-entrepreneur and re-entrepreneur's pressure on business failure and social safety net perception, objective environment perception - a subfactor of social safety net perception - had statistically significant difference between the two potential entrepreneur groups. Conclusions - We categorized potential entrepreneurs into pre-entrepreneurs and re-entrepreneurs. Also, the current study suggests importance of social safety net to vitalize food service business startup by validifying its mediating effect between pressure on business failure and attitude towards restaurant business establishment. This research also established groundwork for future studies on ways to improve entrepreneurial intention or startup business sustainability by deducing social safety net perception difference between pre-entrepreneurs and re-entrepreneurs. This study was able to analyze relationship between those two groups in terms of entrepreneurial intention and startup business sustainability.

In addition to technical skills and competencies, communication competence has been identified to be important to engineering students who will be drivers of innovation in a rapidly changing society. Drawing on the previous studies, this research examines the results of an empirical exploration of engineering students' perception of speaking ability and their communicative competence. To date, there has been most of the research conducted on 'writing' (e.g., its educational process, class designs, ability, etc.) for engineering students. However, relatively little attention has been paid to engineering students' speaking ability perception and their competence diagnosis. This study relies on quantitative data obtained from one survey questionnaire and one test conducted respectively. The sample consists of 386 engineering students as well as 481 non-engineering students for the 1st survey. And to measure communicative competence, 150 engineering students as well as 136 non-engineering students participated in the test. Our findings show that firstly, there were significant differences in perception of speaking ability by majors and gender. Whereas there was no difference in the same survey by grade. Secondly, there was a close and significant relationship between sub-factors of speaking ability. Thirdly, there were significant differences in communicative competence by majors. Whereas there was no difference by gender and grade. Fourthly, there was a close and significant relationship between sub-factors of communicative competence. These findings are expected to provide an explanation for the improvement on engineering students' speaking ability and to encourage the participation in extra-curricular activities and programs in engineering school.
