디지털 중합효소연쇄반응(Digital PCR)은 3세대 PCR로 명명하며, 1세대인 일반 PCR과 2세대인 정량 PCR(Real-time PCR)의 단점을 보완하여 개발된 방법이다. Digital PCR System은 소량의 PCR 반응을 10만개 이상의 반응통(wall)에 적재하는 방식의 나노유체칩에서 쪼개어 증폭시킨 후, target DNA를 계수한다. Target DNA의 증폭 여부에 따라 positive(1)와 negative(0)로 digital signal처럼 받아들여 계수하고, 포아송 분포를 통해 target DNA의 copy를 계산해 최종적으로 샘플 microlitr당 Copy수로 결과 값을 확인할 수 있다. 본 연구에서는 종(種)이 다른 동물의 조직이 서로 섞여있을 때 사람의 조직을 탐색하는 방법으로 유전자 증폭을 할 경우, digital PCR의 유효성에 대해 증명하였다.

다양하게 개발되는 정보시스템은 지속가능경영을 위한 서비스 인프라로 그 중요성이 날로 높아지고 있다. 이에 따라 새롭게 개발된 시스템을 얼마나 신속하게 전파하고 공유하여 조직 경쟁력을 향상시킬 것인가가 생존의 기본 조건이 된 것이다. 그러나, 전파 및 공유 도구로서의 콘텐츠 수준은 단순한 매뉴얼 또는 Help 메뉴 형태로 획일적으로 제공되어 단기간 내 조직 확산에는 한계가 있다. 이를 해결하기 위해 콘텐츠의 활용도를 극대화 할 수 있는 새로운 콘텐츠 개발 요구 정의 방법이 제시되어야 할 필요가 있다. 본 논문에서는 개발된 정보 시스템의 조직 전개를 위해 필요한 콘텐츠를 개발함에 있어 업계에 널리 활용되고 있는 스토리 기반 또는 전통적 콘텐츠 개발 방법의 한계를 극복하기 위하여 요구분석 시 Blue Ocean 전략과 6 Sigma 방법론을 결합한 시스템 개발 BORE Process를 콘텐츠 개발에 적합하게 변경한 Value innovative Requirements Engineering for Contents 프로세스로 제안하고, 콘텐츠 개발에 적용한 후, 그 결과의 유효성을 입증하기 위하여 공인된 기관의 콘텐츠 평가 결과를 제시한다.

This study aims to empirically verify the positive impacts of PB(performance-based) HRM on the organizational effectiveness in a public corporation. The independent variables are 'PB staffing', 'PB appraisal', 'PB compensation'. The dependent variables are 'JS(job satisfaction)', 'OC(organizational commitment)'. The results are as follows. 'PB staffing' shows positive impact on both 'JS' and 'OC', but 'PB compensation' doesn't show positive impact on both 'JS' and 'OC'. Also, it is found that both 'PB appraisal' and 'PB compensation' do not show positive impact on 'OC'. 'PB appraisal' shows positive impact on 'JS', though. From the empirical analysis, the positive effects of the PB-HRM on the organizational effectiveness are partially verified. It is thought that these mixed results are originated from the particular situation in which the surveyed corporation is placed. After the merger of the corporation in 2009, even though it has introduced various PB-HRM systems, it has been through a harsh time such as wage freeze and return as measures of business normalization. This organizational situation may influence the verification of effectiveness of the normal PB-HRM.

오늘날 기업들은 경영환경의 변화와 미래에 대한 불확실성 때문에 어느 때보다 신속한 환경변화에 대한 대응과 위기관리 극복을 위한 노력이 한층 더 중요성을 부각되고 있다. 선행연구들을 통하여 구성원들의 태도가 기업의 효율적인 경영에 중요한 영향을 미친다는 것을 알 수 있다. 따라서 기업의 경영효율성을 높여주는 조직유효성의 요소들을 어떻게 긍정적인 방향으로 높여 줄지가 기업의 중요한 과제라고 할 수 있다. 의료서비스를 제공하는 의료기관들도 급변하는 의료시장의 변화에 맞추기 위하여 기존의 관료적 조직 운영방식에 한계를 느끼고 새로운 변화를 모색하고 있다. 또한 의료시장의 개방, 영리법인 도입 등으로 환경이 급변하고 있어, 의료기관의 경영도 효율성을 강조하고 있는 추세이다. 그러므로 의료기관은 변화에 대처하지 못하면 도태될 수밖에 없으며 살아남기 위한 경쟁력의 원천은 신뢰에 바탕을 둔 조직력이라 할 수 있다. 그러나 의료기관은 관리체계가 일원화 되어 있는 일반 기업과 달리 의료진에 의한 권한체계와 일반 관리자에 의한 이원적 권한체계가 공존하고 있어 효율적인 조직 운영에 어려움이 있다. 그러므로 의료기관에서도 환경변화에 대응하기 위한 대응력을 높이고, 조직 구성원들의 업무 효율성을 극대화시키기 위해 조직을 바르게 관리하기 위한 필요성이 높아지고 있다.

The purpose of this study was to investigate the effect that the job stress of employees would have on the organization effectiveness. In this study, 222 employees in Seoul and Gyeonggi province were surveyed from March to May, 2015 through empirical research with the structured questionnaires, and the collected data were statistically computerized under a statistical package of SPSS 18.0 and analyzed based on the correlation analysis, frequency analysis, and multiple regression analysis. The Following results were derived. First, the job stress of employees according to demographic characteristics had a significance difference. The technical employees had the lower role ambiguity of job stress compare to other group and the higher the income years and educational background, the higher the role overload of job stress. Second, the job stress of employees had a negative effect on the job satisfaction and Organization effectiveness but a positive effect on the turnover intention and the hypothesis was adopted. Thus, it turned out that the job stress of employees had a significant effect on the organization effectiveness and there was a significance at the statistical level. Based on this research finding, it is considered necessary to seek the specific measures that can help reduce the turnover rate of employees and improve their job satisfaction and organization commitment in a more effective methods.

The purpose of this study is to analyze the mediation effect of organizational trust and intrinsic motivation in the relationship between emotional leadership and creativity, suggesting the importance of organizational creativity. Therefore, this study conducted a survey for employees who are working at Korean ICT firms, analyzed the relationship with 241 valid samples, and verified hypotheses using PLS-SEM. The results are as follows. First, emotional leadership had a positive effect on organizational trust. Second, organizational trust had a positive effect on the intrinsic motivation of employees. Third, intrinsic motivation had a positive impact on employees' creativity. Fourth, the organizational trust did not have a positive effect on the creativity of employees. By verifying the mediation effects of organizational trust and intrinsic motivation, this study analyzed the relationship between emotional leadership and creativity, expanding the existing studies of the leadership.

The purpose of this study was to validate the effect that the job stress of the newly appointed dental hygienists would have on the organization effectiveness. In this study, 214 newly appointed dental hygienists in Daegu, Gyeongbuk, were surveyed from September to October, 2013 through the structured questionnaires, and the collected data were electro-statistically computerized under SPSS 17.0 program and analyzed based on the frequency analysis, correlation analysis, and multiple regression analysis. The results of analysis showed that the dental hygienists with less than 3-year experience had the lower role conflict compared to other groups in relation to the job stress factors based on the clinical experience, and there was a significant difference. A negative(-) relation was found among the job stress, organization commitment, and job satisfaction, while a positive(+) relationship with the turnover intention was found. Moreover, it turned out that the job stress of newly appointed dental hygienists had a significant effect on the organization effectiveness. Thus, it is considered necessary to explore the specific measures that can help reduce the turnover rate of newly appointed dental hygienists and improve their adaptation to the organization in a more effective manner.

This study has an objective to analyze the causal relationship between the emotional labor of the members in the private security firms and its effect on their job stress and validity of the organization. To carry out the study, I established a population of private security guards working at the security firms in Seoul. Then a total of 700 question naires were sent out for the survey using the random sampling method of clusters. The study was carried out over about four months, from May, 2014 to September, 2014. A total of 676 questionnaires were used for the final data. 24 questionnaires were excluded either because they were not returned or contained extreme value. In this study, a statistical package of SPSSWIN 18.0 and AMOS 18.0 were used in the data analysis and the causal relationship was verified using the covariance structural equation. The analysis showed the emotional labor to have a positive effect on the validity of organization but a negative effect on the job stress at the statistical level of p<.001 and the hypothesis was adopted. The hypothesis regarding the job stress was also adopted because job stress was found to have a negative effect on the validity of organization at the statistical level of p<.001. In addition, job stress was found to have a negative effect on the relationship between the emotional labor and validity of organization at the statistical level of p<.001. As a result, the hypothesis about the job stress would function as the parameter was only partially adopted.

각 사업소의 교정용 팬톰에 대한 유효성 여부를 판정하고, 측정결과의 정확도와 조직적 오차의 발생여부를 확인할 목적으로 현재 국내 원전에서 사용중인 In Vivo 시스템에 대한 성능 시험을 수행하였다. 성능시험의 내용과 절차는 미국의 관련 지침인 ANSI N13.30에 기초를 두었다. 전신 측정에 대한 성능시험 결과, 시험핵종의 편중, 정밀도 및 최소검출방사능은 ANSI N13.30에서 정한 용인한도 이내로 나타났으며, 또 폐, 하복부 및 갑상선 측정에 대한 성능시험결과에 있어서도 성능평가 항목의 값은 모두 용인한도 이내였다. 각 사업소의 교정용 팬톰과 성능시험용 팬톰이 기하학적 구조에서 다소 차이가 있다 할지라도 측정결과의 편중이 용인한도 이하였다는 사실로부터 각 사업소에서 보유하고 있는 교정용 팬톰의 유효성을 간접적으로 입증할 수 있었다.
