Nonthermal bio-compatible plasma (bioplasma) sources and their characteristics operating at atmospheric pressure could be used for biological cell interactions, especially for plasma bioscience and medicines. The electron temperatures and plasma densities of this bioplasma are measured to be 0.7 ~ 1.8 eV and $(3-5){\times}10^{14-15}cm^{-3}$, respectively. Herein, we introduced general schematic view of the plasma-initiated ultraviolet photolysis of water inside the biological solutions or living tissue for the essential generation mechanism of the reactive hydroxyl radical [OH] and hydrogen peroxide [$H_2O_2$], which may result in apoptotic cell death in plasma bioscience and medicines. Further, we surveyed the various nonthermal bioplasma sources including plasma jet, micro-DBD (dielectric barrier discharge) and nanosecond discharged plasma. The diseased biological protein, cancer, and mutated cells could be treated by these bioplasma sources or bioplasma activated water to result in their apoptosis for new paradigm of plasma bioscience and medicines.

Thus in order to have a better understanding about the KSA(Korean Security association) and to express opinions on its role and security, this paper introduces and discusses about All Japan Security Service Association(AJSSA), which is the prototype of the KSA. There are several positive aspects to consider the introduction of, when these two associations are compared: the traffic security, a supporting member, ex-high-ranking police executive directors practically run AJSSA. These are to enhance financial ability and to promote better relationship with police. KSA needs to improve such relationship and to diversify activities as well. In addition, not just dismissing their duty by giving them the license, AJSSA provides several educations to revitalize the related people so that they can deal in effective and productive services. In another words, JSA perceives it is indispensable to educate the relevant people in the business. In contrast, it is reality that KSA has not put much emphasis on educations. Concisely, the most prompt issue is it should be more beneficial to its members by strengthening itself. Not simply following the example of foreign cases, but putting diverse efforts, KSA can make it substantial and stabilize future private security market in a long term. 본 연구는 한국경비협회의 실태를 파악하고 협회의 역할과 보완에 관한 제언을 하고자 일본전국경비업협회를 소개하고 비교 고찰하였다. 일본의 전국경비업협회와 우리의 한국경비협회 간의 비교를 통해 그 도입을 긍정적으로 고려해 볼만한 것으로서는 여러 가지가 있지만, 무엇보다도 일본 전국경비업협회에서 특이할만한 사항으로 교통유도경비원제도와 찬조회원제도, 전 경찰고위직 출신의 전무이사와 상무이사가 실질적 운영을 한다는 것을 들 수 있는데, 이는 재정의 충원과 경찰과의 관계증진 효과의 제고를 높이기 위한 것이다. 우리도 이러한 경찰과의 관계증진과 더불어 다양화된 활동의 범위를 모색할 필요가 있다. 그리고 일본 전국경비업협회는 자격증 취득 후에도 기타 여러 가지 교육으로 업무의 효과적 대응을 위한 재충전을 해주고 있다. 즉 관련자들에 대한 교육을 중요한 업무로서 수행하고 있는 것이다. 결국 한국경비협회에 가장 시급한 문제는 자체 역량강화를 통하여 회원업체에게 유익한 존재가 되어야 한다는 점이다. 단지 외국의 경비협회제도를 모방하자는 것이 아니라 내실화의 다양한 노력이 미래 민간경비시장의 지속적 안정을 도모할 수 있다는 것이다.

최은하,Eun-Kyung Kim,Pil Bong Kim 한국간호과학회 2018 Asian Nursing Research Vol.12 No.2

Purpose : This study identifies the effects of the educational leadership of nursing unit managers on team effectiveness and the mediating effects of organizational communication satisfaction; it highlights the importance of educational leadership and organizational communication and provides the data needed to enhance the education capacity of managers. Methods : The participants were 216 nurses working at unit with nursing unit managers of staff nurses at a tertiary hospital located in Cheongju city, South Korea, and nurses who had worked for more than 6 months at the same unit. This study was conducted using questionnaires on educational leadership, team effectiveness, and organizational communication satisfaction. Data analysis was performed with a t test, analysis of variance, Scheffé test, Pearson's correlation coefficient, and simple and multiple regression analyses using SPSS, version 23.0. Mediation analysis was tested using Baron and Kenny's regression analysis and a Sobel test. Results : The mean score for the educational leadership of nursing unit managers was 3.74 (±0.68); for organizational communication satisfaction, 3.14 (±0.51); and for team effectiveness, 3.52 (±0.49). Educational leadership was significantly positively correlated with team effectiveness and organizational communication satisfaction. Organizational communication satisfaction demonstrated a complete mediating effect on the relationship between educational leadership and team effectiveness (β = .61, p < .001) and was significant (Sobel test; Z = 7.40, p < .001). Conclusion : The results indicate that the educational leadership of nursing unit managers increases communication satisfaction among nurses; this supports the idea that educational leadership can contribute to team effectiveness. This suggests that the educational leadership and communication capacity of nursing unit managers must be improved to enhance the performance of nursing organizations.

Purpose: The study was conducted to find out clinical characteristics for coronary artery disease patients with diabetes mellitus. Methods: We retrospectively reviewed the electronic medical records which included the data of 6,792 patients, who had been diagnosed coronary artery disease (CAD) such as angina or acute myocardial infarction and admitted to a university hospital in Seoul from January, 2005 to November, 2010. Results: Of the 6,792 patients, 43% had been diagnosed diabetes as comorbidity. The CAD patients with diabetes had lower left ventricular ejection fraction, stayed longer at hospital, and spent on more time from the first symptom to hospital visit than those without diabetes. In addition, they were more likely to have multi vessel coronary artery disease. Conclusion: The CAD patients with diabetes lay on the various factors which can make more worsen condition. Hence, we need to pay attention to specialized nursing care and patient education for the CAD patients with diabetes.

경찰학 전공자와 비전공자의 성 평등의식과 성희롱 통념 비교

최은하(Eun Ha Choi)(崔殷下) 위기관리 이론과 실천 2013 Crisisonomy Vol.9 No.11

본 연구는 경찰관련 학과 전공자 및 그 외 전공자의 성평등의식과 성희롱 통념의 비교조사를 통하여 성인지력을 향상시키기 위한 목적이다. 전공은 성인기 초반의 대학생 진로에 많은 영향을 미치고 있으며, 경찰관련 전공자의 성인지 수준은 경찰 조직문화에 있어 직업사회화의 단면으로 이해된다. 따라서 성평등의식과 성희롱 통념은 향후 경찰조직문화의 의식수준을 가늠할 수 있는 간접적 척도인 셈이다. 최근 경찰은 오랜 남성중심의 조직문화 안에서 여성경찰의 채용확대 및 역할을 다각화로 성인지 감수성이 어느 때보다도 요구되는 시기이고, 이와 같은 추세에 발맞추기 위해서는 입직 전부터 성인권의식의 함양이 우선되어야 할 것이다. 따라서 그동안 대학은 직업의 전문화와 특성화를 위해 노력하여 왔다면 이제는 성인권 교육에 관심을 기울여야 할 때인 것이다. A comparison of police administration major graduates' gender equality consciousness and conventional wisdom toward sexual harrassment and those of other major graduates'. This study aims to enhance sex awareness through a comparison research on police administration major graduates' gender equality consciousness and conventional wisdom toward sexual harrassment and those of other major graduates'. The matter of what to major in a university or a college affects a great deal on any undergraduate' career path in the early stage of his or her adulthood and furthermore the level of a police administration major graduate's sex awareness can be understood as an aspect of occupational socialization in police organization culture. Accordingly, It is natural to say that gender equality consciousness and conventional wisdom toward sexual harrassment are indirect scales that can be used in measuring the level of consciousness of police organization in the future. Presently, sex awareness sensibility has been demanded more highly than ever to the police due to female officers' expended hiring and role diversification in the long time existing male oriented organization culture, therefore awareness of sex human right must be cultivated to keep pace with this trend. Thus while most universities and colleges have endeavored to job professionalization and characterization, now is the high time to pay attention to sex human right education.

This study aims to find a way for the extension of privatization applicable to current situation and its possibility by examining types of cognition about the extension of privatization and the effect of the 6th legal article of civil servants and staffs of private Juvenile Sheltered Housing who have much experience and knowhow from policies and their implementation. This study utilized Q method which found the types of the actual condition and its extension of the privatization of Juvenile Sheltered Housing, and understands and explains their interelationship. As a result from survey, there are three types for the cognition of civil servants: type of authoritative state responsibility(the first type), the type of realistic private reliability(the second), the type of professional education(the third type). The survey also showed that civil servants did not reveal the sense of rejection and indicated an affirmative response about the privatization and diffusion of Juvenile Sheltered Housing r. It is true that it is difficult for all policies and laws to be able to be anchored safely and successfully without civil servants' friendly and positive consciousness. Viewed from this perspective, thie survey about types of civil servants' awareness of law and system making was made, and as a result of it above, the undertone which policies include was very meaningful and positive. On the other hand, as a result of the survey of types of civil servants' awareness in Juvenile Sheltered Housing, it is known that they are 'type of dedicated idealism(the first typoe)', and 'type of humane realism(the second type)'.Civil servants working in Juvenile Sheltered Housing states strong negative opinion about the privatization of private facilities for the purpose of making profit. The survey shows that they, in their own way, are proud of themselves because they think ordinary people have a good sense of awareness about private facilities. It is possibly expected that the result of the above will be used as fundamental material for building the model for diffusion of private Juvenile Sheltered Housing afterwards. 본 연구의 목적은 공무원과 소년보호시설 직원의 인식유형을 조사하고 비교하여 6호 처분 효과와 처분의 민영화 확대에 관한 실태와 우리나라에 적용 가능한 민영화 확대 가능성과 그 방향을 탐색하고자 하는 것이다. 소년보호시설의 민영화 실태와 그 확대에 대해 어떤 생각들을 가지고 있는지 유형을 찾고 그 사이의 상관관계를 이해하고 설명하는 Q방법론 활용하였다. 공무원의 인식유형 조사결과, '권위적 국가책임주의형(제1유형)', '현실적 민영 신뢰형(제2유형)', '전문적 교육형(제3유형)'으로 구분된다. 공무원들 소년보호시설의 민영화나 그 확대에 대해서 거부반응이 없고 매우 긍정적인 반응이 나타났다. 모든 정책과 법 제도도 이를 만들고 도입하는 공무원들의 우호적이고 적극적인 의식이 없이는 성공리에 정착되기 힘들다. 이러한 관점에서 법과 제도 마련과 정착에 관련되어 있는 공무원을 상대로 인식 유형 조사를 한 것이고 그 결과가 나타내는 위와 같은 정책적 함의성은 매우 의미있고 긍정적이다. 반면에 소년보호시설 직원의 인식유형 조사결과, '헌신적 이상주의형(제1유형)', '인간적 현실주의형(제2유형)'으로 구분된다. 이들은 민간시설이라도 경제적 영리 목적의 민영화에는 강하게 부정적인 의견을 피력한다. 민영 소년보호시설에 대한 일반인의 인식도 낮다고 보지 않고 있어서 자부심을 가지고 있는 것으로 나타났다. 위와 같은 결과는 향후 민영 소년보호시설의 확대 모델을 구축하는데 기초적 자료로 활용이 가능할 것으로 기대된다.
