Purpose: The present study was conducted to identify the factors influencing the perfromance of the emergency medical technicians (EMTs) utilizing smart advance life support (SALS) and to provide appropriate feedback to improve SALS performance. Methods: The study subjects were recruited from 119 EMT members working in G city participating in SALS project. A total of 155 data were used in the analysis. Results: Of the three areas, the mean score of importance was the highest (4.53±0.48). followed by educational needs (4.24±0.66), and SALS performance (4.08±0.55). Importance was identified as a significant factor influencing SALS performance (β=.187, p<.047).The length of education. work scope. amd role of level 1 EMTs vary significantly depending on the type of qualifications they have as emergency medical professionals, while the supply of level 1 EMTs has already reached a point of saturation. Accordingly, the current regulation on allowing level 2 EMTs with at least three years of experience to take the level 1 EMT test presents serious inequity for students just graduating from their emergency medical services program. It is also a factor that degrades the professionalism of level 1 EMTs. Conclusion: Based on the results of this study, it was found that mediation and education programs need to be implemented to highlight the importance of the tasks performed in SALS situations in order to improve performance.

Electrodes are one of the types of biosensors capable of measuring bio signals, such as electrocardiogram (ECG) and electromyogram (EMG) signals. These electrodes are used in various fields and offer the advantage of being able to measure ECG signals without the need for skin attachment, compared to Ag/AgCl electrodes. The pur- pose of this study was to evaluate the efficacy of conductive textile electrodes in collecting ECG signals in a bed- like environment. Three adult participants were involved, and a total of 30 minutes of ECG signals were collected for each participant. The collected ECG signals were analyzed to determine the heart rate, normLF and a comparison was made between the conductive textile electrodes and Ag/AgCl electrodes. As a result, the change in heart rate and normLF could be observed, and in particular, the difference between the two electrodes decreased. This study confirmed that conductive textile electrodes can effectively collect ECG signals in a bed-like environment. It is hoped that this research will lead to the development of a system that can detect various sleep-related diseases through the use of these electrodes.

This study attempted to observe muscle activity and muscle fatigue among isotonic exercise of Biceps Brachii and Deltoidus Medius, which correspond to upper limb muscles, using metronome. For the experiment, 13 adult men participated to evaluate biosignals (ECG, EMG). For quantitative evaluation, 1RM and MVIC test were carried out and a constant pace isotonic excise session was conducted. Five sets of exercise were performed, and each set proceeded to the failure point while the speed condition (30bpm) was assigned. As a result of the experiment, muscle activity in both muscles was significantly reduced in fifth set compared to first set. Muscle fatigue has been confirmed to occur at a significant level within the set, but there was only a significant difference in both muscles in the first and second sets between sets. This is similar to the results of previous studies that gives the same rest time(2min), but further research is needed to see if the conditions for the number of repetitions are affected. Based on the recent increase of interest in muscle strength exercise, this study was conducted to observe the results by varying the conditions of common exercise.

팔로워십 척도 개발 및 타당화

Both leadership and followership are important for the success of the enterprises. However followership studies have been relatively weak compared to leadership studies. Furthermore, many followership studies in Korea have been dependent on Kelley’s followership scale which was developed and validated in the United States. The purpose of this study is to facilitate diverse viewpoints and research discussions for followership studies in Korea by developing new followership scale based on Korean employees. The study is composed of literature review and two stages of empirical analysis. The literature reviews cover followership definition, proposed followership competencies and core concepts of major followership studies. In many leadership studies, follower has been granted as same concept of subordinate and followership as a concept which is related with specific position in the hierarchical structure. Recently, however, follower and followership are granted as concepts which are based on the relative role in the each interpersonal interaction. According to this viewpoint, leadership and followership are flexible role-based concepts which are both important to create organizational performance. Considering both leadership and followership are important for organizational performance, current sluggish study of followership is not desirable. By followership scale development, this study intends to promote more active research about followership and contribute more balanced approaches to organizational studies considering both leadership and followership. Empirical studies are composed of panel study by Delphi method and quantitative study by survey method. Delphi method was carried out for the purpose of selecting major followership competencies which were put into quantitative scale development afterward. Through repeated assessment by the panel, 9 major competencies were selected. For quantitative study, 44 items for 9 competencies were developed and measured by web-based survey. The data was collected from 389 employees in several companies based in Korea. Furthermore, 373 responses were put into analysis after filtering out inappropriate responses. Through exploratory and confirmatory factor analysis, 38 items for 7 core followership competencies were identified. The new followership scale was found to be stable by verification of measurement equivalence including configural invariance, metric invariance and scalar invariance. Construct validity was also supported by verification of convergent validity, discriminant validity, nomological validity and incremental validity. Followings are theoretical contributions through the empirical analysis. First, the new followership scale was developed based on Korean employees working with local enterprises while many followership studies have been dependent on Kelley’s scale which was developed and validated in the United States. Through incremental validity analysis, the new followership scale proved to have significant incremental ability to predict some important organizational effectiveness variables after statistically controlling Kelley’s scale. Second, new followership scale encompasses a wide range of competencies. Viewpoints and discussions of previous studies which used Kelley’s scale had some limitations due to simple dimensions of the scale. Although usefulness of the scale cannot be determined by the range of the scale, this new scale at least expand the base for the followership research and discussions. Third, new scale tried to focus on unique followership competencies while many previous studies didn’t care much about differentiation between followership and leadership competencies. This is important to strengthen base for followership study considering that organizational studies by leadership viewpoints have been more vigorous than by followership viewpoints. The limitation of this study is as follows. First, the survey data was collected by conven... 기업의 성공을 위해서는 조직 구성원들의 리더십과 함께 팔로워십도 중요한 요인이다. 그러나 팔로워십에 대한 관심과 연구는 리더십 대비 크게 부진한 상황이다. 특히, 국내의 팔로워십 연구는 고유의 관점을 제안하는 연구가 많지 않은 가운데 미국기업을 기반으로 개발된 Kelley(1992)의 척도를 활용하는 연구가 주를 이루어 왔다. 본 연구는 국내 기업의 구성원을 기반으로 신규 팔로워십 척도를 개발함으로써 팔로워십에 대한 보다 다양한 관점과 논의의 기반을 마련하고자 수행되었다. 팔로워십 측정문항들을 개발한 후 설문을 통해 측정한 373부의 표본을 대상으로 탐색적·확인적 요인분석을 실시했다. 분석 결과 주도적 책임수행, 상생, 진정성, 직무열의, 조직제도 순응, 업무능력, 성실성 등의 7개 팔로워십 역량을 측정하는 38개 문항이 확정되었다. 개발된 척도에 대해 측정동일성 검증을 시행한 결과 형태동일성, 메트릭동일성, 절편동일성 등이 수용됨으로써 기업 구성원의 팔로워십 측정에 활용될 수 있는 척도의 안정성이 확인되었다. 척도에 대한 수렴 및 변별타당도를 검증한 결과 기존 팔로워십 척도와 유의한 수렴타당도가 나타났고, 과업수행, 맥락수행, 변혁적 리더십 등과는 유의한 변별타당도가 나타났다. 이어서 팔로워십 연구들이 준거변인으로서 검증해온 대표적 변인인 정서적 조직몰입과 직무만족을 대상으로 법칙 및 증분타당도를 검증한 결과가 유의하게 나타남으로써, 개발된 척도가 주요 조직 변인을 설명 및 예측할 수 있음이 확인되었다. 이러한 연구결과를 바탕으로 연구의 의의와 제한점, 연구과제 등에 대하여 논하였다.
