The ultrasonic attenuation of low temperature peaks in the PdD_(.67) has been studied. The peak is seen only for longitudinal waves, not for transverse ones, and it is observed only in the deuterides, not in the hydrides. The low temperature peak is correlated with relaxation phenomenon due to redistribution of LO phonons by ultrasonic waves. Ultrasonic attenuation of the PdD_(.67)H_(.02) sample was measured to see the influence of hydrogen in the PdD_(.67); the low temperature peaks of the PdD_(.67)H_(.02) and the PdD_(.67) do not show significant, difference within the limit of experimental error. Ultrasonic attenuations of the PdD_x(x=0.64-0.72) are decreased as the deutrium concentration increased.

This study was aimed at identifying the relations between food service industry employees personal type, emotional intelligence, job satisfaction, customer orientation. The results from the study show that First, Extroversion of personal type had a positive influence on self emotional appraisal. Also, Neuroticism and openness to experience had a positive impact on the use of emotion. extroversion and openness to experience are positively related to the regulation of emotion. Second, the use of emotion and the regulation of emotion of emotional intelligence had a positive influence on job satisfaction. Finally, the hypothesis that emotional intelligence will have a positive impact on customer orientation verified that the use of emotion and the regulation of emotion had a positive influence on customer orientation. It would be able to contribute to the academic and practical development of food service industry management through the study. Also future study should exploit variety of preceding variable, which can affect emotional intelligence of food service employees

Objective: This study examined the educational programs for emergency residency in The Korean Society of Emergency Medicine. Methods: A written survey of the workshop programs with representatives of the related organizations and affiliated organizations was conducted. During the 5-year period, the number of training courses and workshops attended by those who took the professional examination were analyzed. Results: There were 23 workshops in progress. They proceed 2.85 times a year on average. The average number of participants was 22.8 with an average time required for the workshop of 5.6 hours, of which 78.7% is practice time. They received feedback from residency at all workshops, which was reflected in the process. During the 5-year period, the average number of participant training courses was 3.8, and the average number of workshop participants was 2.7. Conclusion: The education program for emergency residency is continuing through the affiliated organizations and related organizations as well as The Korean Society of Emergency Medicine. Encouraging opportunities for participation in various educational programs to supplement those that are not fully experienced will be helpful.

교류 고전계하에서 DGEBA - MDA - SN 계의 흡수열화에 따른 절연파괴 특성

조영신,심미자,김상욱 ( Y . S . Cho,M . J . Shim,S . W . Kim ) 한국공업화학회 1995 공업화학 Vol.6 No.5

DGEBA-MDA-SN 계의 흡수열화에 따른 교류 단시간 절연파괴 메카니즘에 대한 해석을 시도하였다. 흡수열화가 진행됨에 따라 재료 내부에 크랙이 발생, 성장하였으며 침전극과 수지계 계면에서는 박리현상이 관찰되었다. 그리고 유리 전이온도는 감소하다가 강제흡수주기가 3 이상에서는 다시 증가하였으며 절연 파괴강도의 감소와는 일치되지 않는 결과를 나타내었다. 흡수열화에 따른 전기적 성질의 열화는 주로 물리적 성질의 변화에 크게 영향을 받으며 화학적 조성변화, 기계적 성질변화 등 다양한 제반성질의 변화에 대한 관찰을 통하여 해석이 가능하다. The deterioration mechanisms by water absorbing in DGEBA-MDA-SN system at AC high electric field were studied. Microscopic observations indicated the internal crack growth in the resin system and delamination around the needle electrode during forced water absorbing deterioration. The crack growth mainly depended upon the number of heat cycle in water bath. The changes in the glass transition temperature of the materials showed less correlation with the decreases in electrical properties and it was difficult to find out the changes of the chemical structures with FT-IR spectrum analysis. The results showed the physical structure changes such as the crack growth in DGEBA-MDA-SN system deteriorated the electrical properties of the materials.

의료서비스 실패와 회복 후 만족이 신뢰와 행동의도에 미치는 영향 - 일본인 의료 관광객을 중심으로 -

조영신 국제지역학회 2009 국제지역연구 Vol.13 No.2

This research was conducted to explore the factors that cause medical tourists' dissatisfaction, and find ways to solve the tourists' problems by researching on the relationship between the service recovery and the failure of medical services. Also, the research has put more emphasis on establishing marketing strategies that enable Japanese medical tourists to actively visit Korea, and finding out the effects that the medical tourists satisfaction and trust have on their behavioral intentions, recommendations, and positive feedbacks. The summary of the research analysis results as follows. First, the service recovery after the service failure has positive influences on the medical tourist's satisfaction. Second, the service recovery has proven its positive influences on the tourists' trusts and behavioral intentions. Third, the satisfaction of the service recovery has built the mutual trust between the tourists' and the medical center, and this has positive influences on the customer's behavioral intentions. Finally, the research was conducted to analyze the moderating effects on the relationship between the service recovery and the recovery satisfaction. It was found that the medical service failure recognition type has proven no moderating effects. 본 연구는 의료 관광객의 불만을 야기시킬 수 있는 요소를 밝혀내고, 이를 근원적으로 보완할 수 있는 방법을 모색하기 위해 의료 서비스 실패 유형이 회복 수단과 어떠한 상관관계를 가지며 의료 관광객의 신뢰의 형성, 더 나아가 신뢰의 형성을 바탕으로 재이용, 추천, 긍정적 구전의도와 같은 행동의도에까지 어떠한 영향을 미치게 되는가를 규명하여 의료 관광객 관리의 중요성을 시사하며 의료 관광 활성화를 위한 효과적인 마케팅 전략을 수립하고자 하였다. 연구의 주요 분석 결과를 요약하면 다음과 같다. 첫째, 서비스 실패에 대한 서비스 회복은 회복 후 만족에 긍정적인 영향을 미치는 것으로 나타났다. 둘째, 회복 후 만족은 신뢰와 행동의도에 긍정적인 영향을 미치는 것으로 나타났다. 셋째, 회복 후 만족에 의한 신뢰의 형성은 행동의도에 긍정적인 영향을 미치는 것으로 나타났으며 마지막으로, 서비스 회복과 회복 후 만족과의 관계에서 의료 서비스 실패의 조절효과를 분석하였고, 의료 서비스 실패 인지유형은 조절효과를 갖지 못하는 것으로 나타났다.

학습용 스피커 제작 및 특성

조영신 한국물리학회 2004 새물리 Vol.49 No.1

중등학교 교과서에 학습용 스피커에 대한 탐구가 소개되어 있으나 실제 제작시에 출력 음압이 너무 작아서 학습에 어려움이 있다. 공통과학 교과서에 제시된 자료의 문제점들을 분석하였다. 제작과 학습이 용이하며 출력음압이 큰 학습용 스피커를 제작하여 그 특성을 연구하였다. 가장 효율적인 학습용 스피커는 도너츠형 네오디늄 자석 3개를 직립형으로 붙이고 전체 직류 저항이 8 $\Omega$이며 진동부분을 원뿔형으로 제작한 것이었다. 1000 Hz 싸인파의 입력에서 이 스피커의 정격 출력음압은 77 dB으로써 보통 크기의 중등학교 교실 내에 있는 모든 학생이 스피커에서 나오는 소리를 들을 수 있다. 만들어진 실험 안내서에 의하여 탐구 활동을 한 학생들의 반응과 문제점도 연구하였다. There are many diculties whin making loudspeakers a in common subject in science textbooks because the level of sound pressure is too low to hear. Thus, problems in describing how to make a loudspeaker are analyzed, a loudspeaker with a sound-pressure level was designed and examined. The best and most effective loudspeaker was made with three doughnut-shaped Nd magnets, an 8 voice coil and a cone-shape paper vibrator. The sound- pressure level of this working loudspeaker was a 77 dB, 1 Watt, 1,000 Hz sine wave signal at 1 meter from the speaker's front side. Everybody in a normal classroom can hear the sound from this working speaker. Student's response, as well as problems following the lab manual, were also examined.
