Purpose: This study examined the most effective exercise while performing shoulder abduction below ninety degrees. Methods: Thirty two healthy individuals (17 males, 15 females) participated and performed four exercises, 1) Posterior fly, 2) Prone row, 3) Modified prone cobra, and 4) External rotation in the prone position. Surface electromyography (sEMG) was used to measure the electrical activities for the lower, middle and upper fiber of trapezius and serratus anterior. Results: A significant difference in the muscle activities of the upper/middle/lower trapezius and serratus anterior was observed among the three different positions in terms of the PF (posterior fly), PR (prone row), and MPC (modified prone cobra) (p<0.05). In post-hoc analysis, the activities of the lower and upper trapezius were significantly higher than those of the upper trapezius and serratus anterior (p<0.05). In addition, in ERP (external rotation in prone), there was a significant difference in each activity of the muscles. Post-hoc results indicated that the upper trapezius showed greater EMG activity than the other three muscles. Conclusion: External rotation in the prone position revealed the highest activation of the lower trapezius compared to upper trapezius muscle activity. This may be particularly useful in isolating the lower trapezius in cases where excessive scapular elevation is noted. Therefore, the most effective lower trapezius exercise should be performed below ninety degrees of shoulder abduction.

Purpose: This study was conducted to describe core competencies and identify factors affecting core competencies among infection control nurses (ICN). Methods: Infection control nurses from hospital with more than 200 beds comprised the sample. Questionnaires were sent to the sample via e-mail. One hundred and three questionnaires were returned. Data were analyzed with descriptive statistics and stepwise multiple regression via SPSS/WIN 21.0. Results: The core competency level of healthcare workers area was the highest that of the education and research was the lowest. There were significant differences in core competencies related to demographics such as age, clinical carrier, infection control carrier, position, academic degree, infection control specialist license, hospital location, and hospital type. The explained variances for the core competency were 38.3% and the contributing factors to core competencies were infection control carrier and infection control specialist license. Conclusion: It showed various levels of core competencies depending on infection control nurses' demographics and hospital traits, therefore consistent management efforts for the licensing and career path of infection control would be required.

An image exists in the thought of every subjective person and it exercises its influence over everything, having a great power in the real world. An positive image of the nurse has an influence on her faith, value and confidence, therefore increasing her job satisfaction, helping to upgrade her level of profession of nursing through qualitative nursing service as a result, considering the necessity of such an image when it comes to improvement of the profession, the confirmation of the image is indispensable to its evaluation of a speciality in nursing. This study is intended to help that improvement of the nursing profession in the present so that the total effort in every field of nursing is made and to offer basic material for developing a strategy to improve the image of nurses. This study is designed to investigate such an image descriptively. The subjects include 105 nurses, 60 doctors, 68 office workers, 88 medical engineers, 127 patients and there protectors with a total of 448 adapted with accidental sampling, who work at Y and W general hospital in Chonju. The measuring instrument consists of 40 question, with the researcher amended and made from on of Inja Song(1993), Donsoon Lee(1995), Ilsim yang(1998), and its Cronbach's alpha coefficient is .95. Data were collected from March 1 2000 to March 20, 2000 using self-reported questionnairs, analyzed with SPSS WIN 7.5 after encoding. The results are as follows: 1. Most of the subjects thinks the nursing as a hard, stressful, always busy job(more than 75%), and consider nurses as good-looking, supportive and responsible to co-workers to above average degree($50.0{\sim}74.9%$), especially it shows the idea that nursing is independently academic job and has come to fasten itself upon the public. But it shows below the everage($25.0%{\sim}49.9%$) in regard to self development as a specialist, affection for there job, an association activity, service to the community, high intelligence level and direct given patient nursing service. It also rated low as a recommendable job, independently nursing accomplishment, social position. 2. The nurses, patients and there protectors expressed more positive opinions than doctors, medical engineers, office workers about the image of the nurse(F=18.80, p=.00). This fact indicates that the former group evaluated the image similarly contrary to lowness of the latter. 3. In the study on what influenced upon the image, it defines to 79.8% by direct contact in the hospital or acquaintance with nurses, and 16.3% by mass media. 67.3% answered that they saw the image in a new light through hospitalization, which suggests an important source for the image management originates from caring for the quality of nursing service. Considering the evaluation of the image above, we need strategies to lead a unique professional knowledge and technological development, insurance of professional self-determination, high social position, participation in group activities, dedication to lifetime job, in order that nursing comes to expand as a professional occupation. Also, as for generating more positive images, we must take the quality of nursing service into account and offer and monitor correct information about the expanded role and function of the nurse continuously so that mass media reflect a more accurate image of nurses in general.

Objectives : To investigate the fatigue subjective symptoms and VDT related risk factors in bank workers. Methods : A total of 2178 workers (62.8% male, 37.2% female) were surveyed with a self-administered and structured questionnaire consisting of 30 fatigue symptoms and other VDT related factors regarding work characteristics, work postures, work environments, personal medical histories, etc. Fatigue subjective symptoms were divided into 3 groups of 10 questions each: a dull, drowsy and exhausted feeling (Group I), a mental decline of working motivation (Group II), or a feeling of incongruity in the body and dysfunction of autonomic nervous system (Group III). Each question was weighted as 0 for 'none', 1 for 'sometimes', and 2 for 'always'. Results : Mean age was $35.8{\pm}7.2$ years ($38.9{\pm}6.0$ in males, $30.6{\pm}5.8$ in females), Mean work duration was $7.7{\pm}7.1$ years ($8.4{\pm}7.4$ in males, $6.5{\pm}6.4$ in females). Mean symptom score in males was $11.0{\pm}8.1$ ($4.9{\pm}3.1$ in Group I, $3.0{\pm}3.1$ in Group II, $3.1{\pm}2.8$ in Group III) and in females was $17.5{\pm}9.5$ ($7.0{\pm}3.8$ in Group I, $4.6{\pm}3.5$ in Group II, $5.9{\pm}3.4$ in Group III). Mean scores were higher in the order of Group I>III>II. Females had significantly higher scores than males in all three groups (p<0.001). Most common symptoms complained of as 'always' or 'sometimes' were feel strained in the eyes' (85.4%) among Group I, 'find difficulty in thinking'(54.2%) among Group II, and 'feel stiff in the shoulders (72.3%) among Group III. In multiple regression analysis, female, non-straight spine at workstation, more VDT work hours, history of physical therapy, glare of screen, overtime work, young age, and non-horizontal elbow position were significantly related with high score of symptoms. Conclusions : More supportive VDT work environment and education for correct work postures for VDT workers are recommended.

In the non-destructive inspection field, we invest a lot of time and resources in developing the radiation source system to ensure the safety of the workers. However, the probability of accidents is still high. In order to prevent potential radiation accidents in advance, it is necessary to directly verify the position of the radiation source, but the research is still insufficient. In this study, we developed a monitoring system that can detect the position of the radiation source in the source guide tube in the gamma-ray irradiator. The characteristics of the radiation detector are estimated by monte carlo simulation. As a result, the radiation detector for Ir-192 gamma-ray energy was analyzed to have secondary electron equilibrium at $150{\mu}m$ regardless of the semiconductor material. Also, it is expected that the gamma ray response characteristic is the best in $HgI_2$. These results are expected to be used as a basis for determining the optimal thickness of the radiation detector located in the detection part of the future monitoring system. In addition, when developing a monitoring system based on this, radiation workers can easily recognize the danger and secure safety, as well as prevent and preemptively respond to potential radiation accidents.

Purpose: Indoor air quality (IAQ) in the radiation treatment center which is generally located underground is important to the health of hospital workers and patients treated over a long period of time. this study was conducted to measure and analyze the factors related to IAQ and subjective symptoms of sick building syndrome, and to establish the causes influencing IAQ and find a solution to the problems. Methods and Materials : Self administrated questionnaire was conducted to check the workers' symptoms and understanding of the work environment. Based on a preliminary investigation, the factors related to IAQ such as temperature, humidity, fine particulate. carbon dioxide, carbon monoxide, formaldehyde, total volatile organic compounds (TVOC), and radon gas were selected and measured for a certain period of time in specific sites where hospital workers stay long in a day. And we also evaluated the surrounding environment and the efficiency of the ventilating system simultaneously, and measured the same factors at the first floor (outdoor) to compare with outdoor all quality, All collected data were assessed by the recommended standard for IAQ of the domestic and international environmental organizations. Results: Hospital workers were discontented with foul odors, humidity and particulate. They complained symptoms related to musculo-skeletal system, neurologic system, and mucosal-irritatation. Most of the factors were not greater than the recommended standard, but the level of TVOC was third or fourth times as much as the measuring level of some offices in the United States. The frequency and the amount of the ventilating system were adequate, however, the problem arising in the position of outdoor-air inlets and indoor-air outlets involved a risk of the indraft of contaminated air. A careful attention was a requirement in handling and keeping chemical substances including a developing solution which has a risk of TVOC emissions, and repositioning the ventilating system was needed to solve the contaminated-air circulation immediately Conclusion We verified that some IAQ-related factors and inadequate ventilating system could cause subjective symptoms in hospital workers. The evaluation of IAQ was surely needed to improve the underground working environments for hospital workers and patients. On the basis of these data, from now on, we should actively engage in designs of the department of radiation oncology or improvement in environments of the existing facilities.

This study attempts to analyze the factors affecting the intention of transferring to another hospitals among radiology technologists. 344 cases were reviewed in 5 university hospitals and 1 general hospital. Self-administered questionaire were given to study the socioeconomic characteristics, working conditions, job satisfaction level, and the reasons for transfer among the technologists. The major findings were as follows : 1. Job position and hospital characteristics had a statistically significant relationship with the intention of transferring to another hospital. 2. Those who were not satisfied with their salaries and promotional opportunity showed a higher tendency towards to transfer. 3. Those who were less satisfied with the opportunity for developing the personal ability and had the negative attitude on their job showed a higher tendency to transfer. 4. Those who did not sustain good relationship with their superiors and co-workers scored high on the tendency to transfer. 5. In the result of mutiple regression, recognition of radiation hazard, job satisfaction, satisfaction with salary levels, job attitude were significantly related to transfer. The above indicate that besides economic incentives, job satisfaction and organizational culture to promote their ability and form a good relationship with organization members were very important to decrease the intention of transfer. Since these results represent only 6 hospitals from a limited area, more hospitals nationwide, especially small and medium-sized institutions where there is a high turnover rate of employment, need to be examined in order to investigate the various factors that affect the intention of transferring.

Purpose: This study was conducted to identify factors that affect nursing performance; Those factors are personal characteristics, sub-categories of empowerment and job satisfaction of clinical nurses. Methods: Data were collected from November 24, 2012 to March 11, 2013, and participants were 451 hospital nurses in 6 hospitals. Descriptive statistics, t-test, one-way ANOVA, Pearson correlation coefficient, and stepwise multiple regression were used for data analysis. Results: Nurses who were older, married, highly educated, in the position of charge nurse, and with longer clinical careers showed relatively higher empowerment, higher job satisfaction, and higher nursing performance than others. Also, there were strong correlations between nursing performance and empowerment (r=.576)/job satisfaction (r=.617). Factors predicted nursing performance were relationship with coworkers (${\beta}=.398$), duty (${\beta}=.181$), promotion system (${\beta}=.134$), and turnover intention (${\beta}=-.109$). Factors predicting job satisfaction were competency of empowerment (${\beta}=.249$), and clinical career (${\beta}=.151$). These 6 factors explained 55.2% of the variance in nursing performance (F=93.37, <.001). Conclusion: Regarding human resource management, relationship with co-workers is a changeable factor. Therefore nursing organizations should apply these factors in human resource management to enhance nursing performance and achieve organizational goals.

Purpose: This preliminary study is aimed at developing standardized tools for psycho-social assessment of patients in needs for hospice/palliative care. To accomplish the purpose, investigators examined effects of perceptions of social workers on the importance of psycho-social domains of assessment in hospice/palliative care settings. Moreover, investigators paid attention to variances of perceptions of social workers' along with types of institution and credentials of those family settings. Methods: A form of questionnaire was first explored from an initial interview assessment of 10 government-certified hospice care providers and a literature review, second constructed with eight domains and 80 items, and sent by e-mail to 55 institutions and hospitals providing hospice/palliative cares in Korea. Lastly, a total of 31 agencies returned with a completed responses and consent form (56% response rate). SPSS program (version 18.0) was used for data analysis. Results: Study found that social workers perceived patients' family background (m=4.53, 5-point scale) as the most important assessment domain, whereas economic conditions (4.06 point) the least important. Social workers' perception varied by credentials (i.e., license types, training, full-time position, types of care facility). Conclusion: Based upon study findings, investigators can conclude strong needs for developing a assessment tool that measures multiple domains (i.e., psychological, social and ecological aspects) of patients. A standardized assessment tool should be structured with 2 axis (center/core and expanded/peripheral) and tailored for institution type. Second, professional trainings must be provided by strengthening legal institutionalization and fostering qualified social workers with full responsibilities of hospice and palliative care patients.
