The 4th year medical students were randomly divided and designated as group HF and LF, representing high and low fidelity simulations respectfully. Both groups performed OSCE on 2 topics(adult intubation and IV cannulation) with each composed of the same scenario. Each scenario was developed by a faculty in charge of clinical skill education with supervision from 2 other faculty members. High fidelity simulations were designed as in-situ simulations in real OR. Low fidelity simulations had the same scenarios but the environment was simulated only with a simple task trainer in the classroom. All students participated in series of survey using a Likert scale before and after the simulations. The provided data was anlayzed with paired T-test and Mann-Whiteney test(p<0.05). The post simulations self evaluation score for group HF was lower than pre-simulation self confidence score for both topics of adult intubation and IV cannulation where as for group LF, it was lower only for adult intubation(p<0.05). In group HF, the needs for clinical training on both topics increased after the simulation. In group LF, there was no significant change of needs for clinical training between pre and post simulation survey. This suggest that fidelity may be a helpful factor to improve the motivation of the students and further study on economical aspect should be addressed.

Objectives: Sound and light (SL) stimulation has been used as a method to induce some useful mental states in the fields of psychology and psychiatry. It is believed that sound and light entrainment device (SLED) has some specific effects through synchronization of EEG in patients who use it. Theta frequency is believed to stimulate deep relaxation and short term memory processing. This study was conducted to evaluate if 4-10 Hz SL stimulation can induce relaxation and improve short term memory function. Methods: Ten medical students with no medical or psychiatric problems participated in this study. Subjects were randomly divided into two groups. One group was applied with real SLED was applied to one group (R group) and pseudo SLED to the other group (P group). The two groups were exposed to SL stimulation with SLED 15 minutes a day for 5 days, and after two days rest the two groups were switched over. The Korean Wechsler Adult Intelligence Scale (K-WAIS), Academic Motivation Tests (AMT), Test Anxiety Scale (TAS), Korean Auditory Verbal Learning Test (K-AVLT), and digit span were used to evaluate short term memory. Spielberger's State-Trait anxiety inventory and heart rate variability (HRV) test were used to evaluate degree of relaxation. Results: Compared with S group, R group showed a significant improvement in K-AVLT and digit span after a single application of SL stimulation. But 5-day long application did not reveal any differences between the two groups. A significant change in HRV was observed in 5-day long application of SL stimulation after being switched over to other SLED. Conclusion: This pilot study suggests that 4-10 Hz SL stimulation has some positive influences on short term memory and relaxation.

Purpose : This study assessed the improvement of competency levels for participants, as well as their satisfaction from completion of the special international disaster response program. Methods : The program structure followed an intensive two-week course that included a combination of lectures, discussions, case studies, and field trips. "ICN Framework of Disaster Nursing Competencies" was used for designing the program. A pre-post survey was done to measure the change in the competencies of students and assess their satisfaction after finishing the program. Focus group interviews were also performed to further understand the attitudes of participants toward the disaster issues. Results : The overall pre-program test score for disaster competency was $2.18{\pm}0.68$ and the post-program test score was $6.30{\pm}0.84$, which showed statistically significant gains in all competency items (p <.001). The general satisfaction of participants with the program was quite high, demonstrated by a mean score of $4.5{\pm}0.51$. The benefits for students from program participation included increased knowledge and better understanding of the important roles of international organizations and NGOs. Conclusion : The international disaster education programs are necessary to provide an opportunity for students to increase their disaster competency. In addition, future development of a unified educational competency framework is also necessary.

정보기술의 발달과 함께 소프트웨어 제품은 모든 산업에 필수요소가 되었고, 품질과 평가에 대한 관심도 점차 증가되고 있다. 하지만 일부 산업에서는 소프트웨어 품질 평가에 대한 사용자들의 만병 통치적 기대, 품질 표준의 부족, 측정을 위한 양질의 데이터 부족, 소프트웨어 분석과 디자인에 대한 공학적 한계로 소프트웨어 품질 평가에 대해 많은 문제점이 지적되고 있다. 국내에서도 의료산업 관련 정보시스템의 오류 및 사용자들의 운영 미숙은 매년 많은 금액의 사회적 비용을 증가시켰고, 병원정보시스템의 품질에 대한 관심을 초래하였다. 특히, 산업적 특성이 강한 병원정보시스템은 성공적 구축을 위해 사용자 중심의 소프트웨어 디자인과 다양한 전문가들의 지식 통합이 필요하며, 정보시스템 품질 측정으로 연구자들과 개발자들의 시스템 설계 혼란을 감소시키는 방법론이 필요하다는 연구들이 등장하고 있다. 대부분의 병원정보시스템이 단편적인 업무처리 위주로 개발 운영되고 있고, 장기적 경영전략이나 임상연구를 위한 분석적 정보처리 기능들은 결여되어 있다. 또한 소프트웨어 재설계나 추가적 개발 에 활용될 수 있는 객관적 품질 기준이 부족하고, 사용자들의 요구사항에 대해 소프트웨어 설계에 있어서 효율적으로 반영되지 못하고 있다. 이에 본 연구는 최근 발표된 병원정보시스템 품질 평가에 대한 연구 경향을 종합하고, 품질 평가에 대 해 효율적으로 활용되고 있는 사용성(Usability)을 기준으로 병원산업의 특수성을 포함한 품질 평가 방법과 품질척도를 제안하고자 한다. 국제표준기구(ISO:International Standards Organization)에서는 품질 특성을 기능성, 신뢰성, 사용성, 효율성, 유지 보수성과 이식성의 특성을 제시하고 있다. 특히 Folmer & Bosch(2004)가 정리한 ISO9126에서는 품질의 특성을 배움의 용이성, 운영의 용이성, 이해성과 매력성으로 분류하였고, ISO9241-11는 효과성, 효율성과 만족성으로 분류하였다. 또한 Shackel(1991)은 배움의 용이성(배움과 시간, 기억력), 효과성(오류, 직무시간), 유연성과 마음가짐으로 분류하고 있다(Shackel, 1991). Nielsen(1997)은 배움의 용이성, 기억의 용이성, 오류, 효율성, 만족성으로 분류하고 있고(Nielsen, 1997), Shneiderman(1998)는 효과성(직무시간, 배움의 시간), 효율성(기억의 지속시간, 오류), 만족도를 품질의 특성으로 분류하였다. 이와 같은 소프트웨어의 품질은 소프트웨어 계획, 개발, 성장과 쇠퇴의 모든 과정에 적용되며, 환경적 변화에 따라 사용자들의 정보욕구를 적절하게 반영하여 만족도를 높이 는 것이라고 요약할 수 있다. 그러나 현재까지 소프트웨어 품질 평가에 대한 연구들 은 보편적인 평가 항목들을 대상으로 측정하여 일반적인 품질기준을 제시하고 있고, 유사한 측정 내용들이 중복되어 있다. 이러한 경향은 산업별 특수성이 강한 소프트웨어에 대해서는 정확한 품질측정이 어려웠고, 품질측정에 대한 신뢰성을 떨어뜨리는 계기가 되었다. 이러한 한계를 극복하고자 나타난 방법론이 최종사용자들의 요구사항을 얼마나 적절하게 시스템에 반영했는지에 대한 사용성(Usability) 측정이다. 사용성에 대한 정의는 사용자들이 실질적으로 일하는 장소에서 직접 사용자들의 시스템 운용실태를 파악하여 문제점을 개선하는 것으로 요약할 수 있다. ISO9124-11에서는 사용성을 "어떤 제품이 구체적인 사용자들에 의해 구체적인 목적을 달성하기 위한 구체적인 사용의 맥락에서 효율성, 효과성을 만족함으로 사용될 수 있는 정도"로 정의하고 있다. 지난 10년간 병원정보시스템 평가에 대한 문헌들을 고찰한 결과 품질 측정의 효과는 정보화에 대한 동기유발과 의료품질을 높이는 게기가 되었으며, 질병에 대한 예방효과도 높은 것으로 조사되었다. 그러나 평가에 대한 인식의 문제, 평가 방법의 신뢰성 부족, 평가 지침과 부분적 평가에 따른 인증의 어려움 평가 결과에 대한 확산과 단편적 연구의 한계 등으로 연구결과에 대한 신뢰도와 활용도는 낮은 것으로 조사되었고, HIS에 대한 연구 빈도와 범위 가 매우 미약하였다. 특히, 품질속성은 같은 용어이지만 연구자에 따라 전혀 다른 측정 내용을 제시하고 있어 효율적인 품질 지표를 제시하는데 많은 혼란을 초래하고 있다. 이러한 품질 평가의 경향은 시스템 설계 및 개발자들에게 필요한 사용자들의 구체적이고 독특한 욕구나 병원정보시스템 환경의 특수성 파악에 한계를 보였으며, 평가 범위도 부분적으로 이루어져 전사적 시스템 설계 및 개발에 중요한 자료를 제공하지 못하고 있다. 이러한 문제점과 한계를 극복하고자 ISO와 같은 품질 표준 속성과 컨텍스트(Context)를 중심으로 사용자에 의한 평가 척도의 설정은 구체적이고 실용적이며 신뢰성 있는 평가 방법이 될 것이다.

The epidemiological researches on the inpatients hospitalized at the oral medicine ward have been continuously carried out since 1970, and most researches have been performed by centering around the oral medicine wards of college hospitals. Numerous specialists have been produced after the establishment of oral medicine, and they have been active in various fields. As dental clinics have gotten bigger, the function of oral medicine in the secondary clinics is being brought out. As admissive channel, case features, case composition and otherwise have not been researched for a long time, the related researches should be carried out from now on. Hereupon, this study was carried out by targeting the 100 inpatients hospitalized at the oral medicine ward of Sun Hospital located in Daejeon Korea, through questionnaire. As the result, the following results were derived. 1. The ages of the inpatients in Sun Hospital were $29.21{\pm}11.31$ on the average; 71 females' mean average was $29.63{\pm}11.29$ and 29 males' mean average was $28.17{\pm}11.48$. In regard of school career, the patients who finished high-school course or higher accounted for 78%; the patients' school career seemed to be relatively high. The patients who complained of temporomandibular pain accounted for the highest proportion with 65%. In motivation to visit this hospital, internet surfing was 11%, mass media was 10%, acquaintance's introduction was 38%. The patients, who were hospitalized at another hospital due to the same symptom, accounted for 56%. The dental clinics, which made the patients visit this hospital, accounted for 20%. The patients, who were previously aware that the present symptom should be treated by oral medicine, accounted for 38%. The patients, who were not aware of the fact in advance, were 62%. The respondents of 51% answered that they were aware of the fact one month or below before hospitalization. 2. The patients, who complained of craniocervical ache, accounted for 58%; the patients, whose ache aches affect dailylife, were 22%. Continuous ache was 14% and intermittent ache was 68%, and dull pain was 23%. 3. Life variations were compared with each other by using SRRS (Social Readjustment Rating Scale). In consequence, the variation within 3 years indicated a significant difference in the both groups but the variation within 6 months did not indicate any differences. 4. In regard of the questionnaire on the incidents happened for a week, the ache-group was compared with the group free from the ache. As the result, the number of strain arisen for a week, the decrease of favorite works and sudden fear indicated a significant difference. Pleasant feeling and the decrease of interests in looks did not indicate a significant difference, but came close to the significance. 5. In the questionnaire on impatience, the ache-group indicated higher value but there was not a significant difference. 6. In the questionnaire on the symptoms caused by stress, the two groups indicated significant differences in the item of 'the teethridge itches and feels a tooth rising' and 'the occiput or the nape is stiff.' In the item 'the inside of the cheek or the teethridge are widely peeled off, accompanied with ache and hemorrhage', 'the face has acne or pimple' and 'headache frequently attacks', a significant difference was not observed but the two groups came close to the significance.
