PURPOSE: The purpose of this study was to examine the immediate changes in the weight-bearing ankle dorsiflexion range of motion (ROM) and the dynamic balance in asymptomatic subjects using the modified Star Excursion Balance Test (SEBT) after ankle balance taping (ABT) and placebo ABT with kinesiology tape METHODS: A total of 23 active participants (11 men, 12 women) volunteered for this study. Ankle flexibility was assessed using the weight-bearing lunge test, and dynamic balance was assessed using the modified SEBT. Participants were asked to respond to questions regarding their perception of stability, reassurance, and confidence when performing modified SEBT. RESULTS: The weight-bearing ankle dorsiflexion ROM did not show a significant decrease after real ABT or placebo ABT compared to the ROM prior to ABT. The anterior, posterolateral, and posteromedial reach distances of SEBT did not increase significantly after real ABT or placebo ABT compared to the distances prior to ABT. However, the participants' perception of stability, reassurance, and confidence, when performing SEBT with real ABT, was increased compared to that during the control trial. CONCLUSION: This study showed that although real ABT did not immediately improve the reach distances in the 3 directions during modified SEBT, it improved the participants' perception of stability, reassurance, and confidence without decreasing weight-bearing ankle dorsiflexion ROM.

The research studies the classic beer game simulation model from a new perspective. It does so by providing each agent with two ordering policies, and creating a set of rules that allow an agent to change its policy. Such a change is triggered based on an agent's confidence in their own performance, and on the relative confidence of their nearest neighbour. The overall effect is that policy diffusion can occur, where, under certain circumstances, an agent will mimic the behaviour of its neighbour, if it believes that its neighbour is performing better. The motivation behind this research is to provide an experimental base upon which the decision making strategies of business agent can be studied.

Purpose: Bystander cardiopulmonary resuscitation (CPR) improves survival. However, there have been few studies on the performance of bystander CPR in Korea. This study was done to identify the reasons for being unwilling to perform CPR, and to investigate the factors associated with performing CPR on a stranger in an emergency situation. Method: The participants in this study were 444 local residents. Data were collected by using self-reported questionnaires from May 1 to June 30, 2010. For data analysis, descriptive statistics and multiple logistic regression were performed using SAS version 9.1. Result: Only 32.2% of respondents reported being willing to perform CPR on a stranger. The major reason for not being willing to perform CPR on a stranger was "have no confidence to perform CPR well". From multiple logistic regression analysis, statistically significant predictors of CPR performance on a stranger were found to be a higher educational level (OR=6.11, 95% CI 1.46-25.52), neighbors with angina pectoris or myocardial infarction (OR=6.65, 95% CI 3.93-11.24), and having confidence of performing CPR (OR=3.02, 95% CI1.78-5.14). Conclusion: CPR education (including automatic external defibrillator) should be offered to family members and neighbors. In addition, the Good Samaritan Law must be given wider publicity at the national level.

This study aimed to help build a quality control program to improve cardiac arrest treatment via analysis of medical records in a local tertiary general hospital to evaluate factors that influence clinical outcomes of in-hospital cardiac arrest. At first, the medical records of in-hospital cardiac arrest were analyzed, and targeted surveys about functional and structural factors associated with cardiopulmonary resuscitation (CPR) were conducted amongst the workforce in charge of cardiac arrest treatment. From January 2012 through June 2013, a total of 486 adult cases of in-hospital cardiac arrests, except for those occurring in the emergency room, were enrolled in this study. Among the patients, those of recovery of spontaneous circulation were 57.8%; 13.8% of patients were discharged alive; 8.9% of patients were discharged without significant neurologic sequela. Despite CPR is usually successful when administered as quickly as possible, in this analysis showed that prompt reaction after initial recognition was significantly lower in nurses compared with doctors. Analysis of survey results showed that confidence in performing CPR was significantly associated with the experience of CPR in doctors, while in nurses educational experience showed a correlation. In order to improve quality of in-hospital CPR system maintaining and increasing confidence of CPR performance is the most important factor. Therefore it can be helpful to develop and apply a phased, customized education program using training simulators as well as personalizing them to increase the personnel's confidence in CPR performance.

본 연구는 건강한 삶을 위하여 중학생 대상으로 한 심폐소생술 교육 전·후 수행자신감에 관한 연구이다. 본 연구에서 도출된 주요 연구결과를 중심으로 결론을 제시하면 다음과 같다. 성별에 따른 중학생의 심폐소생술 교육 전·후 수행자신감의 차이가 있었다. 교육을 받기 전 남학생과 여학생의 자신감에는 통계적으로 유의미한 차이를 발견하지 못했다. 그러나, 교육을 받은 후 남, 여 학생 모두 심폐소생술 수행 자신감이 높게 나타났다. 연구에서 심폐소생술 수행 교육과 심폐소생술 수행 자신감 간의 높은 양의 상관성을 보인 결과와 일치하는 것이다. 이 같은 결과는 최소 초등학생 고학년 이상의 연령 이후의 심폐소생술 교육은 심폐소생술 수행에 대한 긍정적인 태도와 자신감 형성에 중요한 요인임을 확인한 것이다. 이는 심폐소생술 수행 교육자 연령이 낮을수록 주위에 심정지 환자가 발생했을 때 망설임 없이 심폐소생술을 시행할 수 있는 자신감 형성과 관계가 있음을 알 수 있다. 이는 심폐소생술 수행 자신감 향상을 위해서는 중학생에게 심폐소생술 교육을 반드시 이수하도록 제도적인 장치를 마련해야함을 시사한다. 또한, 심폐소생술 교육 후의 평가방법 종류에 수행자신감 차이를 확인하기 위한 추가 연구도 수행되어야 할 것으로 생각된다.

Purpose: The purpose of this study is to analyze the effects of COVID 19. The effects of COVID 19 are grouped into 5; economic stress, mental stress, health stress, task concern, self-confidence. We introduce the concept of personal ambidexterity that is necessary power for cabin crews to provide appropriate and efficient service to passengers. Ambidexterity consists of exploiting existing resources to sustain and exploring the new including method of performing task, customer, market etc. The former is necessary to maintain present condition while the latter is necessary to prepare for the future. Also motive is considered as a stimulating factor for task. Previous studies show that motive affects ambidexterity and we try to analyze whether COVID 19 effects influence this relationship. Research design, data, and methodology: Considering the relationship between the variables, we designed to measure the influence of the effects of COVID 19 by analyzing the moderating effects of them. For empirical analysis we distributed survey questionnaire and collected. Total of 361 samples are used fo the analysis. For analysis program, SPSS version 23 was used. Regression analysis and moderating effect analysis were conducted. Results: Study results show that first, the variables of economic stress, mental stress, health stress, task concern, self confidence affects personal ambidexterity and service provision. Also ambidexterity affects service provision significantly. Among COVID 19 effects, economic stress, task concern, and self confidence has moderating effects. On the other hand, new work environment does not have moderating effect. Conclusions: In conclusion, the effects of COVID 19 are wide and various. Among them the most serious effect is that COVID 19 is depriving workers of self confidence and passion toward the work. To remedy stresses and restore self confidence and passion, each worker should make his/her own efforts, such as, learning more to become more competitive, also firms should do make efforts to protect employees and to rebuild trust between firm and employees in every respect. Especially firms should realize that economic stress can be treated by economic compensation as the situation turns to normal but trust as well as self confidence and passion is not easy to restore.
