21세기에는 지식정보와 커뮤니케이션이 산업의 중요한 열쇠가 될 것이다. 현대 기업환경의 변화는 과거와 다른 양상으로 나타나고 있으며 경영자들에게 기업경영과 기업의 의미에 대해 새로운 패러다임을 요구하는 상황에 이르렀다. 이러한 변화추세로 예측해 본 학자들은 21세기 대표적인 조직 모델로 소위 "가상기업" 을 내세우고 있다. 가상기업은 네트웍을 통하여 세계 최고수준의 기술력과 지식을 집결하여 제품 또는 서비스를 고객의 요구에 신속하게 대응하는 전략이자 시장변화와 Mass Customization에 대응하는 고객가치 지향적 네트웍 솔루션으로 정의될 수 있다. 본 논문은 우리나라 중소기업이 처한 경영환경의 어려움을 헤쳐 나갈 수 있는 방안으로 그 실마리를 가상기업 인프라 구축에서 찾아보고자 한다. 여기서 가상기업의 중요성을 인식하고, 선진기업들이 가상기업을 성공적으로 수행하는데 있어 그 성공요인은 무엇이며, 그 과정상의 문제들을 어떻게 극복하는지를 문헌조사, 사례분석 등을 통해 분석, 연구하여 국내 중소기업들을 위한 급변하는 지식정보사회에서의 대처 방안을 모색하고자 하였다. 이를 위해 국내 중소기업의 근본적인 경쟁력을 강화하고 향상 시킬 수 있는 가상기업인프라 구축을 위한 지식관리시스템의 개념적 모형을 개발하였다.

Objective: This study was evaluated the behavior intention of emergency medicine residents before and after education using a vignette case about professionalism, particularly in physician impairment. The residents’ reaction to this type of education was evaluated. Methods: Thirty-four residents from five teaching hospitals participated in this education program consisting of lecture and discussion using cases. They wrote their behavioral intention and their opinions before and after education. Their satisfaction and reaction to the education experience were also collected. Results: The frequencies of the common reasons for the action or the basis of the judgment, concerns during decision making, and desired help were similar, but their action decisions changed into more systemic and reasonable ones after the education. They had fewer learning experiences of non-clinical skills and were satisfied with this type of professionalism education. Furthermore, they felt the importance and educational needs of professionalism beyond this topic and would cope with similar problem situations the way they learned in this education. Conclusion: In the professionalism education using the case discussion of impairment and self-monitoring, little had changed in the participants’ reasons for the action, concerns when decision making, and desired help, but their behavior intentions changed as they learned. This study provided the opportunity to recognize the importance of professionalism, patient safety, and peer relationship. Small group discussions using the vignette case can be suggested to provide professionalism education for the emergency medicine residents.

Purpose: This study was performed to develop a self-efficacy theory-based exercise program for total knee arthroplasty (TKA) and to test the program's efficacy in ameliorating knee pain and restoring function as measured by lower extremity muscle strength, 3 meter walking time, Korean Western Ontario McMaster Index (WOMAC), exercise self-efficacy, and length of hospital stay for TKA patients. Methods: This quasi-experimental study incorporating a non-equivalent control group and pretest-posttest non-synchronized design non-synchronous design was applied to assess self-efficacy reinforcement strategies based on self-efficacy theory. The exercise program consisted of the following steps: TKA, education to prevent postoperative complications, and muscle strength exercises. Respective exercise and control groups included 29 and 27 participants. The experimental group received eight sessions of the program from three weeks before TKA to four weeks after TKA. Collected data were analyzed using the chi-square test, Mann-Whitney U test, and ranked ANCOVA and t-tests using IBM SPSS Statistics 23. Results: Experimental group showed significant improvement in lower extremity muscle strength (F = 8.63, p = .005), 3 meter walking time (z = -5.02, p < .001), WOMAC index (z = -2.22, p = .027), self-efficacy for exercise (z = -3.29, p = .001), and length of hospital stay (t = -2.11, p = .040) compared to the control group. No significant differences in knee pain and range of motion were observed. Conclusion: These findings indicate that a self-efficacy theory-based exercise program can be an effective exercise strategy that patients undergoing TKA can easily follow at home without assistance. It is thus recommended as an exercise intervention for TKA patients.

This study examined the temporal relationship between social activities and physical functioning in older adults. Two waves of 2001 and 2003 data, from the SLAS (Suwon Longitudinal Aging Study), of 537 people aged 65 years or over, were analyzed. Social activities were measured by using items related to the frequency of contact with relatives, friends, and neighbors, and religious and cultural activities. Physical functioning(PF) consisted of measures of mobility, activities of daily living(ADLs), and instrumental activities of daily living(IADLs). We examined the direction of the association by using cross-lagged panel technique to test causality through longitudinal study as a substitute for a controlled experiment. Then hierarchical regression models were fitted to examine if social activities affect physical functioning independently, or vice versa, adjusting for sociodemographic and health-related covariates. Cross-lagged panel design showed that the correlation between social activities ratings at Wave 1(2001) and PF 2 years later was higher than the correlation between PF at Wave 1 and social activities ratings 2 years later. After adjusting for sociodemographic and health-related covariates, the effect of social activities on PF remained significant, but not for PF on social activities. Results suggest that social activities contribute to older person's physical functioning. Further work, however, is needed to confirm the potential causal association by controlled experiments. 노인의 사회활동과 신체기능과의 관계에 대한 최근 연구들은 두 요인 사이에 강한 연관성을 제시하고 있다. 그러나 노인이 사회활동을 많이 하기 때문에 신체기능이 좋은 것인지, 신체기능이 좋기 때문에 사회활동에 많이 참여하는 것인지, 그 연관성의 방향에 대한 증거는 부족한 실정이다. 이에 본 연구는 노인의 사회활동과 신체기능의 두 요인 중 어떤 요인이 선행요인인지를 밝히고자 하였다. 이를 위해 2001~2003년에 걸쳐 수행된 수원시 종적 노화연구의 1, 3차년도 자료를 이용하여 65세 이상 재가노인 537명의 사회활동(친척ㆍ친구ㆍ이웃과 접촉빈도, 종교 및 문화활동) 점수와 신체기능(PF 척도) 점수간의 관계를 살펴보았다. 먼저 시차적 교차패널기법(Cross-lagged panel technique)을 통해 1차년도 사회활동-3차년도 신체기능간의 상관과 1차년도 신체기능-3차년도 사회활동간의 상관관계를 비교함으로써 선행요인을 알아보았다. 다음으로 각 변인들의 독립적인 효과를 알아보기 위하여 혼란변수들을 통제한 상태에서 각각 선형회귀분석을 실시하였다. 시차적 교차패널분석 결과, 1차년도 사회활동-3차년도 신체기능의 상관계수가 1차년도 신체기능-3차년도 사회활동의 상관계수보다 더 높았다. 회귀분석 결과 사회활동이 신체기능에 미치는 효과는 통계적으로 유의하였고, 그 효과는 인구사회학적 변인들(연령, 성, 교육수준, 수입)과 건강관련 변인들(주관적 건강인식, 인지건강, 만성질병의 개수, 운동빈도)을 통제한 후에도 유의하였다. 한편 대응되는 관계인 신체기능이 사회활동에 미치는 효과는 통계적으로 유의하였으나, 인구사회학적 변인들과 건강관련 변인들을 통제한 후에는 그 효과가 유의하지 않았다. 이 결과를 통해서 사회활동이 신체기능의 원인으로 작용하며, 노인의 사회활동이 많을수록 신체기능이 양호하다는 사실을 추론할 수 있다. 노인의 사회활동과 신체기능간 인과관계를 파악한 결과는 노인의 사회활동과 신체기능의 관계에 대해서 종전보다 깊이있는 이해를 가능하게 하며, 노인관련 임상분야나 정책부문에 있어서 노년기 건강상태 증진을 위해서도 노년기 사회활동 프로그램의 활성화가 필요함을 시사해준다.

Purpose: Action learning is an educational method, whereby participants study their own actions and experiences to improve performance. We aimed to study the effects and share the experiences with action learning to teach clinical performance examination (CPX). Methods: Twenty-eight fourth-year medical students participated in this study in 2010. This course consisted of three mini-lectures,three CPX practice sessions, and an evaluation. Satisfaction and improved and deficient elements in the CPX practice session were investigated. Internal consistencies of peer evaluation and CPX scores were also investigated using Cronbach’s α. Results: Average satisfaction was 4.5 on a 5-point scale. Low Cronbach’s α was noted for the consistencies of peer evaluation and patient-physician interaction. The most common improved element was self-confidence, followed by accustoming themselves to conversation with the standard patient. Seven students stated that they were deficient in self-confidence; other deficiencies were sympathy expression, conversation, and physical examination. Conclusion: CPX education using action learning by peer evaluation, generating CPX cases by themselves, repeated practices, and feedback, effected self-active learning. However, the educator and educatee must invest much time and effort. Allotting specific,scheduled times for this type of education would be more effective.
