본 연구는 유치원 교사의 공감능력과 가정연계효능감이 교사-학부모 관계 인식과 교사소진에 미치는 효과가 어떠한지, 그리고 공감능력과 유치원 교사가 인식하는 교사-학부모 관계 및 교사소진의 관계에서 가정연계효능감의 조절효과가 유의한지를 확인하고자 하는 목적으로 수행되었다. 이를 위해 충북지역에 근무하는 공·사립 유치원 교사 208명을 대상으로 설문을 실시하였고, JAMOVI 1.6.23을 활용하여 응답자료를 분석하였다. 주요 연구결과는 다음과 같다. 첫째, 유치원 교사의 공감능력과 가정연계효능감 모두 교사-학부모 관계 인식에 유의한 정적효과를 보였다. 둘째, 유치원 교사의 공감능력과 교사-학부모 관계 인식에서 가정연계효능감의 유의한 조절효과가 나타났다. 구체적으로 유치원 교사의 가정연계효능감이 높을 때(M+1SD) 공감능력이 높을수록 교사-학부모 관계 인식이 유의하게 높아졌으며, 가정연계효능감이 평균 수준이거나 낮을 때(M-1SD)는 공감능력이 교사-학부모 관계 인식에 미치는 효과가 유의하지 않았다. 셋째, 유치원 교사의 공감능력과 가정연계효능감 모두 교사소진에 유의한 부적효과를 나타냈으며, 공감능력과 교사소진의 관계에서 가정연계효능감의 조절효과는 유의하지 않았다. 본 연구는 유치원 교사가 인식한 교사-학부모 관계와 교사소진에 있어 공감능력과 가정연계효능감의 역할을 확인하고, 특히 공감능력이 교사-학부모 관계 인식에 미치는 효과가 가정연계효능감 수준에 따라 조절됨을 확인함으로써 가정연계효능감의 중요성을 인식하였다는 점에서 의의가 있다.

Background: Nodal invasion by colorectal cancer is a critical determinant in estimating patient survival and in choosing appropriate preoperative treatment. The present meta-analysis was designed to evaluate the diagnostic value of endorectal ultrasound (EUS) in preoperative assessment of lymph node involvement in colorectal cancer. Materials and Methods: We systematically searched PubMed, Web of Science, Embase, and China National Knowledge Infrastructure (CNKI) databases for relevant studies published on or before December 10th, 2014. The sensitivity, specificity, likelihood ratios, diagnostic odds ratio (DOR) and area under the summary receiver operating characteristics curve (AUC) were assessed to estimate the diagnostic value of EUS. Subgroup analysis and meta-regression were performed to explore heterogeneity across studies. Results: Thirty-three studies covering 3,016 subjects were included. The pooled sensitivity and specificity were 0.69 (95%CI: 0.63-0.75) and 0.77 (95%CI: 0.73-0.82), respectively. The positive and negative likelihood ratios were 3.09 (95%CI: 2.52-3.78) and 0.39 (95%CI: 0.32-0.48), respectively. The DOR was 7.84 (95%CI: 5.56-11.08), and AUC was 0.80 (95%CI: 0.77-0.84). Conclusions: This meta-analysis indicated that EUS has moderate diagnostic value in preoperative assessment of lymph node involvement in colorectal cancer. Further refinements in technology and diagnostic criteria are necessary to improve the diagnostic accuracy of EUS.

Primary cultures of rat fetus brain exhibit phenotypes of neuron, oligodendrocyte, and astrocyte from "neurospheres". To understand the role of mitogen-activated protein kinase (MAPK) cascade and gap junctional intercellular communication (GJIC) in the differentiation of neurosphere-derived astrocyte, we investigated the effects of 12-O-tetradecanoylphorbol-13-acetate (TPA) on the cultured astrocyte morphology.(omitted)

BACKGROUND/OBJECTIVES: This study aimed to examine the association of Japanese schoolchildren's involvement in at-home meal preparation with food intake and cooking skill. SUBJECTS/METHODS: We included 1,207 fifth-grade children aged 10-11 years and one parent of each child. A cross-sectional survey was used to collect data on involvement in at-home meal preparation. Correspondence analysis was used to classify involvement in at-home meal preparation into three groups: food-related activities (cooking only or with other activities such as shopping, table-setting, clean up, and dishwashing), non-food-related activities (table-setting and/or clean up), and no (helping) activities. Food intake was assessed using a food frequency questionnaire. Logistic regression models were used to examine involvement in at-home meal preparation associations. RESULTS: The sample consisted of 1,207 fifth-grade children. Vegetable intake was lower in the no (helping) activities group than the food-related activities group (95% CI; boys: 1.2, 5.1, girls: 2.0, 8.9). Fewer children in the non-food-related activities group reported they were able to make a portion of their meals compared with the food-related activities group (95% CI; boys: 1.6, 3.5; girls: 1.5, 3.2). CONCLUSIONS: Children in the food-related activities group showed more favorable food intake and cooking skills than children in the no (helping) activities or non-food-related activities group.

The Maglav system project affects communities and are usually funded by public agencies. Evaluation of this project that considerably impact whole communities requires public involvement. This specific requirement of transportation projects determines the method of their evaluation as the impacts are estimated from the transportation economic point of view. Especially evaluation criteria must reflect the needs of the interested parties and should consider all foreseeable benefits and losses caused by the Maglav project. To select evaluation criteria and evaluation method may help a decision--maker in making a best selection for a Maglav project.

본 논문은 신뢰할 수 있는 제 3의 기관이 없는 SIP 기반의 VoIP 환경에서 RSA 공개키 분할 전송을 이용한 SRTP키 교환 기법을 제안한다. 제 3의 기관이 요구되는 기존 SRTP 키 교환 기술들은 PKI 환경 구축에 대한 부담으로 실제 적용되기 어렵다. ZRTP의 경우 PKI 환경 구축없이 SIP 단말 간에 안전하게 SRTP 키를 교환할 수 있지만, SRTP 키 교환시 사용자가 직접 개입해야 하는 불편함이 있다. 제안 기법은 RSA 공개키를 분할하여 시그널링 세션과 미디어 세션으로 나누어 전송함으로써 제 3의 기관이 없을 때 발생할 수 있는 중간자 공격을 어렵게 하여 안전하고 사용자의 개입을 요구하지 않는다. 또한 제안 기법은 SRTP키 교환을 위한 보안 요구사항들을 만족하고, PKI 환경 구축이 어려운 실제 VoIP 환경에 적용이 용이하다.

This study investigates public receptivity to celebrity's climate change advocacy on YouTube through a semantic network analysis. The results of this study suggest that the YouTube video generated a number of viewers' responses. Celebrity endorsement not only leaded public voices on climate change issue, but also their opinions on the celebrity endorser. This study found that most of viewers were polarized in their judgment and attitude toward the celebrity advocate either positively or negatively. This study offers an exploratory examination of the perceived star power and the role of celebrities as spokespersons for social causes. This study contributes to the theoretical foundation of the role of celebrity advocacy using social media. In addition, this study offers methodological insights into how to detect public perceptions and attitudes toward celebrity endorsement of social causes by analyzing public comments.

Public infrastructure is crucial to promote and sustain a sustainable economic growth and a health community. A large amount of capital investment is generally required in infrastructure projects that motivate the involvement of the private sector in the delivery process. Various relationship-based procurement methods have been attempted to maximize value-for-money. In this paper, the problems and challenges that relationship-based procurement methods have been facing are explored. A particular focus is placed on the challenges for the public-private partnership (PPP) model. Possible strategies for adapting the PPP models in the post-Global Financial Crisis era are proposed and discussed. In addition, the challenges facing alliancing, which is one of the other important relationship-based procurement methods, are also examined. Views on infrastructure procurement in the future were sought from industry professionals via interviews and are reported in this paper as well.
