Purpose: We investigated the neurogenic potentials of amniotic fluid-derived stem cells (AFSCs) according to the expression levels of stem cell markers and ingredients in the neural induction media. Materials and Methods: Four samples of AFSCs with different levels of Oct-4 and c-kit expression were differentiated neurally, using three kinds of induction media containing retinoic acid (RA) and/or a mixture of 3-isobutyl-1-methylxanthine/indomethacin/insulin (neuromix), and examined by immunofluorescence and reverse transcription-polymerase chain reaction (RT-PCR) for their expression of neurospecific markers. Results: The cells in neuromix-containing media displayed small nuclei and long processes that were characteristic of neural cells. RT-PCR analysis revealed that the number of neural markers showing upregulation was greater in cells cultured in the neuromix-containing media than in those cultured in RA-only medium. Neurospecific gene expression was also higher in Oct-4 and c-kit double-positive cells than in c-kit-low or -negative cells. Conclusion: The stem cell marker c-kit (rather than Oct-4) and the ingredient neuromix (rather than RA) exert greater effects on neurogenesis of AFSCs.

본 연구의 목적은 중소병원 간호사의 직장 내 괴롭힘, 직무스트레스, 조직몰입, 이직의도를 파악하고, 이직의도 영향요인을 확인하기 위함이다. 본 연구 대상자는 G 광역시와 J도에 소재한 300병상 미만 6개 중소병원 간호사 140명을 대상으로 자료를 편의 표집 하였다. 수집된 자료는 SPSS Win 21.0 프로그램을 이용하여 서술적 통계, T 검정, 분산분석, 상관분석, 단계적 다중 회귀분석을 이용하여 분석하였다. 회귀모형은 통계적으로 유의했고(F=37.11, p<.001), 이직의도에 대한 설명력은 34.2%였다. 대상자의 이직의도에 영향을 미치는 변수는 조직몰입(β=-.41, p<.001), 직무스트레스(β=.25, p=.005)순이었다. 질 높은 의료서비스 제공을 위해서는 인력관리가 중요한 문제이다. 본 연구결과 중소병원 간호사들의 이직의도감소를 위해서는 직무스트레스는 낮추고, 조직몰입을 높이는 것이 중요하다. 본 연구결과를 토대로 추후 중소병원 간호사들의 이직의도를 감소시키고 효율적인 의료인력관리를 도모하기 위해서 중소병원 간호사 맞춤형 프로그램 개발 및 적용이 필요할 것으로 사료된다.

A cross-sectional study was conducted to examine the prevalence and related factors of musuculoskeletal symptoms in automobile manufacturing, steel processing, electric assembly line, and wood processing industries. A study subjects were 3,434 workers from small and medium scale companies of Incheon. Walk-through surveys were performed from Feb. of 2004 to Oct. of 2004 to investigate various physical work factors. Symptom prevalence rate by related factors was that women worker showed higher rate than man, and married person was higher than single person. For the working year, group of person who were working less than 3 year showed the highest rate. However, the group of person who were working more than 10 hour per day showed the highest rate. For the total subjects, prevalence of symptoms by body area was as follows: shoulder symptoms were the most frequently reported symptoms(253 person, 7.0%), followed by back(155 person, 4.5%), hand or fingers (136 person, 4.0%), lower extremities(131 person, 3.9%), neck(108 person, 3.1%), and elbow symptoms(97 person, 2.8%).

Objectives: The purpose of this study was to provide hospital management diagnosis status and basic data required for the future development of hospital management diagnosis program. Methods: We conducted a questionnaire survey on administrative staff of manager level or over of medical institutions in B metropolitan city. Results: As a result of analyzing the relative influence of the needs by hospital management diagnosis indicator, the effect of financial analysis indicator, patient treatment record indicator and medical revenues indicator were high in the medical institutions with number of beds of 100 beds or over and general hospital level or over both on a hospital level and on an individual level. Conclusions: Since the existing laws or systems are centered on large major hospitals, the management environment is very unfavorable for small and medium hospitals as can be seen from the results of this study. Therefore, the government should improve the transparency and rationality of the hospital management environment in Korea through regulation and system reforms that can be applied to all medical institutions.

The purpose of this study was to investigate the effect of fairness, culture, and service points on organizational management to maximize the ability of organizational members. The subjects of the survey were selected from major hospitals, small and medium hospitals. A total of 500 questionnaires were distributed, but 404 (80.8%) were used for the final analysis. The SPSS WIN 20 program was used to analyze the collected data. The following conclusions were obtained. First, in this study, organizational fairness did not show any general difference, and fairness was obtained with relatively high scores. In terms of improving organizational culture, size of hospital there is a statistically significant difference. the larger the organization, the more the organizational culture needs to be improved. Organizational fairness were significant differences in service encounter points and size of hospital. Second, the correlation between fairness, organizational culture improvement, service contact point and management performance showed a very positive correlation. Third, fairness has no effect on business performance. However, in this study, organizational culture improvement and service contact points are statistically significant and positive (+) influence on dependent variable management performance. Therefore, in order to improve the organizational culture of the hospital, it is necessary for the CEO to the vision, core, to discuss and make a reasonable plan. In order to actively cope with rapidly changing hospital environment, it will be necessary to positively support the of new medical market and the increase of market share.

The radiosurgery treatment is one time, non surgical approach to the treatment of patients with intracranial disorders whose conditions would be difficult or dangerous to treat with conventional sugical procedures. The LINAC based radiosurgery is based on the combination of multiple isocentric arc irradiation with small fields centered in the stereotactic target. The absorption of the beam in a tissue equivalent medium, such as water, as well as the uniformity, or profile, of the beam must be precisely documented. The beam characteristics and dosimetric measurememts of the 6MV X-ray beam from a ML-6M linear accelerator are examined. The percent depth dose (PDD) and beam profile (including flatness, symmetry and penumbra) is calibrated with the radiosurgery cone in water phantom. The cone is made of lead which size is from $10{\times}10mm{\phi}$ to $30{\times}30mm{\phi}$ All of these dosimetric measurements sufficiently characterized the beam to permit safe clinical use.

Purpose: The purpose of this study was to conduct a comparison analysis on requirements of online continuing education requirements according to practical experience of nurses at small and medium-sized hospitals. Methods: Data had been collected with 236 nurses from May to June, 2015. The data were analyzed with the use of SPSS. Results: Among them, 45.8% participated in online continuing education. Nurses in beginning level required musculoskeletal diseases (20.9%), care for injuries and stomas (5.8%), and surgical disease and operation care (4.7%). Competent nurses required musculoskeletal diseases (19.7%), cerebrovascular diseases (9.9%), emergency care and CPR (8.5%), and medical nursing (8.5%). Skillful nurses required cerebrovascular diseases (13.9%), care for internal diseases (8.9%), and rehabilitation care (8.9%). Among the educational contents of diseases, the items that were significantly different according to practical experience were operation management ($x^2$=23.92, p<.001) and drug care ($x^2$=7.85, p=.020). Among continuing education methods, the items that were significantly different were video ($x^2$=16.81, p<.001), webtoon ($x^2$=8.96, p=.011), and test ($x^2$=10.56, p=.005). Among continuing education evaluation methods, the items that were significantly different were multiple-choices ($x^2$=9.43, p=.009) and OX ($x^2$=6.47, p=.039) based quizzes. Conclusion: Based on the study results, it is necessary to develop a differentiated continuing education program according to practical experience of nurses.
