This study identifies influential factors for invigorating the public management office (PMO) system for system integration (SI) projects in public sectors and analyzes the priority of each factor from the point of different stakeholders, i.e., owners, SI company, and PMO. Based on the literature review, four first-level influential factors are identified: legal system maintenance, owner's capability, SI company's capability, and PMO's capability. Among them, the PMO's capability is determined as the most critical factor by all the stakeholders. Among the second-level influential factors, the capabilities of professional engineers and project managers are considered as important among the PMO's capability, whereas the reasonable consulting fee is considered as the most critical factor among the legal system maintenance. With respect to each stakeholder, project management capability is considered as the most important factor for owners, while the reasonable consulting fee is considered as the most important factor for PMO.

이 연구는 청소년의 미디어 소비가 급증하고 있는 상황에서 미디어 교육 경험과 미디어를 제대로 이해하고 활용할 수 있는 능력인 미디어 리터러시가 비판적 사고 성향에 어떠한 영향을 주는지에 초점을 맞추고 있다. 연구 결과, 미디어 교육 경험은 비판적 사고 성향에 긍정적 영향을 미치는 것으로 나타났다. 특히 학교에서의 미디어 교육 경험은 비판적 사고 성향의 모든 하위 영역에 긍정적인 영향을 미쳤고, 가정에서의 미디어 교육 경험도 진실 추구성을 제외한 모든 영역에 긍정적인 영향을 미쳤다. 그리고 미디어 리터러시 구성 요소 중에서 산업적 동기는 비판적 사고 성향의 모든 하위 영역에 영향을 주는 것으로 나타났다. 기술적 활용 능력은 체계성을 제외한 나머지 영역에 영향을 미치는 것으로 나타났고, 자아 표현은 탐구성, 객관성, 체계성, 자기 신뢰성에 영향을 주었다. 수용자는 개방성, 체계성, 자기 신뢰성에 영향을 미치고 있었으며, 미디어 언어는 진실 추구성, 개방성, 객관성에 영향을 주는 것으로 나타났다.

최근 기업의 평균수명이 점점 단축되고 있으며 기업환경 또한 급격하게 변화하고 있다. 따라서 본 연구에서는 일본 시니세의 장수요인 분석을 통하여 기업의 장수, 즉 계속기업의 해답을 얻고자 하였다. 시니세의 조사 결과와 함께 도라야, 데이코쿠 두 시니세의 장수요인을 분석해 본 결과 그 요인은 신용과 전통, 고객맞춤상품개발, 경영방식의 변화, 글로벌 시장 개척 등의 요인이 장수의 핵심요인으로 설명되었다. 또한 본 연구에서는 이러한 주요요인을 중심으로 계층적 의사결정기법(AHP)을 이용하여 각각의 사례와 선행연구에서 조사된 요인의 중요성을 분석하여 장수요인에 대한 주요 변수를 예측 및 분석하였다. 그러나 변수선정과 사례의 성공요인이 갖고 있는 한계점 등을 고려해 볼 때 공통적 성공 요인으로 분류하기 위해서는 많은 사례가 필요할 것으로 볼 수 있다. 본 연구는 향후 장수요인을 분석하는데 매우 유용한 지침이 될 수 있을 것으로 기대된다.

Background: Pre-B-cell colony enhancing factor (PBEF) has been suggested as a novel biomarker in sepsis and acute lung injury. We measured the PBEF in bronchoalveolar lavage (BAL) fluid of acute critically ill patients with lung infiltrates in order to evaluate the clinical utility of measuring PBEF in BAL fluid. Methods: BAL fluid was collected by bronchoscope from 185 adult patients with lung infiltrates. An enzyme-linked immunosorbent assay was then performed on the collected fluids to measure the PBEF. Results: Mean patient age was 59.9 ${\pm}$14.5 years and 63.8% of patients were males. The mean concentration of PBEF in BAL fluid was 17.5 ${\pm}$88.3 ng/mL, and patients with more than 9 ng/mL of PBEF concentration (n=26, 14.1%) had higher Acute Physiology and Chronic Health Evaluation (APACHE) II and Sequential Organ Failure Assessment (SOFA) scores on the BAL exam day. However, there were no significant differences in clinical characteristics between survivors and non-survivors. In patients with leukocytosis (n=93) seen on the BAL exam day, the linear regression analysis revealed a significant, positive relationship between PBEF and APACHE II ($r^2$=0.06), SOFA score ($r^2$=0.08), Clinical Pulmonary Infection Score ($r^2$=0.05), and plateau pressure in patients on ventilators ($r^2$=0.07) (p<0.05, respectively). In addition, multivariate regression analysis with PBEF as a dependent variable showed that the plateau pressure ($r^2$=0.177, p<0.05) was correlated positively with PBEF. Conclusion: The PBEF level in the BAL fluid may be a useful, new biomarker for predicting the severity of illness and ventilator-induced lung injury in critically ill patients with lung infiltates and leukocytosis.

For large scale applications of high temperature superconductor (HTS) such as transmission cables, motors and generators, long length of flexible HTS conductor is required. Currently, Bi-2223 HTS tape is capable of being fabricated in longer than 100 m length by industrial processes. In this study, we fabricated 100 m 19 filamentary Bi-2223 ($Bi_{1.8}Pb_{0.4}Sr_2Ca_2O_{10+x}$) HTS tape by PIT (Power in Tube) process. Critical current(IC) of this long length tape was measured 18.5 A at 77K, self field. Critical current of 100 m length tape was mainly resulted from the increase of inhomogeneity in oxide from the increase of inhomogeneity in oxide layer. Engineering critical current (Je=Ic/total tape cross-section area) that is important factor for practical applications and fabrication cost was measured 2.2 kA/cm2.

Critical success factors (CSFs) have been replicated and applied in a wide variety of settings for more than two decades. Most previous research on CSF have focused on identifying critical factors, based on the variance theory, in terms of the correlation between individual factor and Information system (IS) success. However, it is unknown how a set of critical factors Influence each other and lead to IS success, which means the process of IS implementation. in this research, we aim to understand how a set of critical factors influence each other and lead to IS success in the context of IS implementation for Customer Relationship Management based on the process theory. This research has implications In explaining a mechanism leading to CRM systems success based on the influencial relationships among the critical factors.

The purpose of this study was to identify the relationships among critical thinking disposition, professional self-concept and clinical competence in nursing students. The participants were 291 nursing students in Gwangju Province. A questionnaire survey was conducted from March 02 to 16, 2013. Data were analyzed using descriptive statistics, t-test, ANOVA, Scheffe test, pearson's correlation coefficients, and stepwise multiple regression analysis with SPSS/WIN 20.0 version. There was a significant positive correlations among critical thinking disposition, professional self-concept, and clinical competence. The variable predicting clinical competency were professional self-concept and critical thinking disposition. These factors accounted for 44.1% of the variance. The findings of this study suggest that the most influential factor for clinical competence was professional self-concept. Therefore it is necessary to improve professional self-concept through effective education program.

The objective of this study is to analyze the relationship between the watershed characteristics and the critical duration of design rainfall. For estimation of critical duration, adjustment Huff's method and ILLUDAS urban runoff model were applied to urban 21 areas. Watershed characteristics such as area, channel length, channel slope, shape factor, and pipe density were used to simulate correlation analysis. The conclusions of this study are as follows; it is revealed that critical duration is influenced by the watershed characteristics such as pipe density, area and channel length. Also, multiple regression analysis using watershed characteristics is carried out and the determination coefficient of multiple regression equation shows 0.972.

This study attempts to suggest a new approach of the estimation of range and degree of fisheries damages caused by a large scale of reclamation undertaken in coastal area using the central limit theorem(CLT) in statistics. The key result of the study is the introduction of the new concept of critical variation of environmental factor($d_{c}$). The study defines $d_{c}$ as a standard deviation of the sample mean($\bar{X}$) of environmental factor(X), in other words, $\frac{\sigma}{ \sqrt{n}}$. The inner bound of $d_{c}$ could be the area of fisheries damages caused by public coastal undertaking. The study also defines the decreasing rate of fisheries production$\delta_{\varepsilon}$, in other words, degree of fisheries damages, as the rate of change in the distribution of sample mean(($\bar{X}$), caused by the continuous and constant variation of environmental factor. Therefore $\delta_{\varepsilon}$ can be easily calculated by the use of table of the standardized normal distribution.
