This meta-analysis was performed to assess the implementation effects of clinical pathways in patients with gastrointestinal cancer. A comprehensive search was conducted in the Cochrane Library, PubMed, EMBASE, Web of Science and Chinese Biomedical Literature Database (from inception to May 2014). Selection of studies, assessing risk of bias and extracting data were performed by two reviewers independently. Outcomes were analyzed by fixed-effects and random-effects model meta-analysis and reported as mean difference (MD), standardized mean difference (SMD) and odds ratio (OR) with 95% confidence intervals (CI). The Jadad methodological approach was used to assess the quality of included studies and the meta-analysis was conducted with RevMan 5.1 software. Nine citations (eight trials) involving 642 patients were included. The aggregate results showed that a shorter average length of stay [MD = -4.0; 95% CI (-5.1, -2.8); P < 0.00001] was observed with the clinical pathways as compared with the usual care. A reduction in inpatient expenditure [SMD = -1.5; 95% CI (-2.3, -0.7); P = 0.0001] was also associated with clinical pathways, along with higher patient satisfaction [OR = 4.9; 95% CI (2.2, 10.6); P < 0.0001]. Clinical pathways could improve the quality of care in patients with gastrointestinal cancer, as evidenced by a significant reduction in average length of stay, a decrease in inpatient expenditure and an improvement in patient satisfaction. Therefore, indicators and mechanisms within clinical pathways should be a focus in the future.

Government Publications are published to keep records of governmental activities and performances. In a rapidly changing information-oriented society, it is badly required for the operation system of government publications and a library to be effectively managed with government publications for satisfying 'right to know' of people and improving the obligation of government to 'let people know.' Accordingly, the purpose of this paper is to analyze such five research items as the situation of the publication and distribution of, government publications, the operation system of the publications in library, the number of publications regarding secondary information sources for the publications, and the legal deposit of the publications in the National Library, in order to proceed with a subject as to how much the government publication is satisfying 'right to know' of people. The research findings were suggested as follow : 1) Despite the fact that the publication of government publications has been gradually increased every year in numbers and kinds, it is unfortunately pointed out that the publications, distributions and sellings of them were not well organized and systematic. That is, the government publications had not been published more than 1.47% of all publications in number. Moreover, more than the half of the publications were non-periodically or annually published. To make the matter worse, it was not easy to get an access to the publications because of the publications not to be sold. 2) It a n.0, ppears that people could not use the publications efficiently because the library and administrative document office did not pay sufficient attention to public relations for all sorts of government publications. Not only that, there were not enough numbers of publications regarding such secondary information sources as bibliography, index and catalog. A speedy searching capacity for the information gave rise to another serious problem which the government publications could not be effectively used. 3) It is legally stated that all sorts of government publication should be deposited to the National Libraries. However, the law was not properly put into force because of lack of understanding of government agencies about the law.

본 연구에서는 대학도서관 사서를 대상으로 도서관서비스 접점에서 발생하는 사서의 감정노동이 직무와 관련된 상사의 감성지능, 사회적 지원, 도서관서비스 제공수준에 미치는 영향을 알아보았다. 이를 위하여 전국의 218개 4년제 대학도서관 중에서 국공립 13개, 사립 28개의 총 41개 기관의 사서를 대상으로 설문조사를 실시하였다. 회수된 응답지 529부(회수율 99.2%)를 SPSS 버전 21.0 통계 프로그램을 사용하여 신뢰도분석, 요인분석, 판별타당성분석, 상관관계분석, 변량분석, 단순회귀분석, 다중회귀분석을 실시하였다. 연구 결과 서비스산업 분야 종사자의 감정노동이 직무만족에 부정적인 결과를 초래한다는 기존의 연구와는 달리, 사서의 감정노동은 오히려 조직의 직무와 관련된 상사의 감성지능, 사회적 지원 및 도서관서비스 제공수준에 긍정적인 영향을 가져왔다. 이러한 결과는 일반 서비스산업 분야의 감정노동자들과는 달리 대학도서관 사서는 상대적으로 감정노동을 스트레스로 적게 인식하고 있을 뿐만 아니라 이용자 만족을 충족시키고자 하는 직업적 마인드가 크기 때문에 감정노동에 있어 긍정적 효과가 나타난 것으로 판단된다. 따라서 도서관서비스의 질적 향상을 위해서 사서의 감성 지능을 강화하는 훈련프로그램이 필요하다.

Numerous studies have been conducted regarding association between TNF-${\alpha}$ and oral cancer risk, but the results remain controversial. The present meta-analysis is performed to acquire a more precise estimation of relationships. Databases of Pubmed, the Cochrane library and the China National Knowledge Internet (CNKI) were retrieved until August 10, 2013. Pooled odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated with fixed- or random-effect models. The heterogeneity assumption was assessed by I-squared test. Among the eight included case-control studies, all were focused on TNF-${\alpha}$-308G>A and four also concerned the TNF-${\alpha}$-238G>A polymorphism. It was found that oral cancer risk were significant decreased with the TNF-${\alpha}$-308G>A polymorphism in the additive genetic model (GG vs. AA, OR=0.19, 95% CI: [0.04, 1.00], P=0.05, I2=68.9%) and the dominant genetic model (GG+GA vs. AA, OR=0.22, 95% CI: [0.06, 0.82], P=0.03, I2=52.4%); however, no significant association was observed in allele contrast (G vs. A, OR=0.70, 95% CI: [0.23, 2.16], P=0.54, I2=95.9%) and recessive genetic models (GG vs. GA+AA, OR=0.72, 95% CI: [0.33, 1.57], P=0.41, I2=93.1%). For the TNF-${\alpha}$-238G>A polymorphism, significant associations with oral cancer risk were found in the allele contrast (G vs. A, OR=2.75, 95% CI: [1.25, 6.04], P=0.01, I2=0.0%) and recessive genetic models (GG vs. GA+AA, OR=2.23, 95%CI: [1.18, 4.23], P=0.01, I2=0.0%). Conclusively, this meta-analysis indicates that TNF-${\alpha}$ polymorphisms may contribute to the risk of oral cancer. Allele G and the GG+GA genotype of TNF-${\alpha}$-308G>A may decrease the risk of oral cancer, while allele G and the GG genotype of TNF-${\alpha}$-238G>A may cause an increase.

Are the benefits derived from ICT based reference and information service worth the financial and other commitments devoted to it? In an attempt to answer this, this study delved into finding out the perceived benefits; the rational for ICT based reference services in Nigerian university libraries. The main objectives were to find out the purposes for using ICT facilities in reference services delivery and the perceived benefits derived from using ICT resources in reference and information services. Being a survey, questionnaire was used to collect data from the librarians of twelve (12) universities; two (2) each sampled from the six geopolitical zones of Nigeria. Data was analyzed using frequencies, mean scores and standard deviations. ANOVA statistical analysis was used to test the hypothesis of no significance difference in the benefits derived from ICT based reference services using p-value of 0.05 to calculate the level of significance. Findings showed that librarians and library users made use of ICT facilities for different reference purposes especially to obtain information they need using the internet. Other reference needs for which patrons used the ICT facilities included: - access to current e-books and e - journals, user education and access to global information in other libraries. Provision of current awareness services (CAS) and selective dissemination of information services (SDI), on-line searching using workstations in the library, provision of on-line public access catalogue (OPAC) services, keeping statistics of users of the reference section and compilation of bibliographies. Further findings showed that the librarians and library users derive a lot of benefits from their use of ICT facilities in reference services. The results showed that easy retrieval and dissemination of information to patrons were ranked highest by the librarians amongst others.

Objectives: Depression is a frequent complication of type 2 diabetes mellitus. This study aimed to investigate the relationship between low social support and risk for depression in people with type 2 diabetes through a meta-analysis. Methods: PubMed, ProQuest, SpringerLink, ScienceDirect, Scopus, the Cochrane Library, Embase, and Google Scholar were searched for English-language articles published up to 2021. Pooled adjusted odds ratios (aORs) were calculated using a random-effect model with 95% confidence intervals (CIs). Heterogeneity was evaluated by using the Cochrane Q test and I² statistics. The risk of publication bias was estimated using a funnel plot, the Egger test, and the Begg test. The Joanna Briggs Institute Critical Appraisal Tools were used to assess the quality of evidence and the risk of bias. Results: Eleven studies were included in this meta-analysis, containing a total of 3151 people with type 2 diabetes mellitus. The pooled analysis showed that people with type 2 diabetes mellitus who had low social support had twice as high a risk of depression as those with high social support (aOR, 2.02; 95% CI, 1.51 to 2.70; p<0.001). A random-effect model was used because the heterogeneity was high (I² = 87%). Conclusions: Low social support was found to increase the risk of depression among people with type 2 diabetes mellitus. Further investigation into factors that may moderate this relationship is required.
