This study investigated the influence of job motivation on job performance of library personnel in university libraries in Oyo State, Nigeria. Descriptive survey research design type was used for the study. The population of the study consisted of 164 library personnel in university libraries in Oyo State. An adapted questionnaire was used as the instrument for data collection. The data collected were analyzed using both descriptive and inferential statistics. PPMC were used for hypotheses testing at a 0.05 level of significance. The findings of the study revealed that the level of job performance of library personnel among university libraries in Oyo State was high ( x =2.85) and that the level of job motivation (promotion, compensation, conducive work environment) of library personnel among the sampled universities was also high ( x =2.77). More so, the findings of the hypothesis disclosed that there is a significant and positive relationship between job motivation (p= 0.029 < 0.05) and job performance of library personnel among universities in Oyo State. It was recommended that library leadership should make provision for motivational ingredients that can serve as an encouragement for the library personnel to enhance the level of their job performance.

Background: To identify the optimal cost effective strategy for the management of women having ASC-US who attended at King Chulalongkorn Memorial Hospital (KMCH). Design: An Economical Analysis based on a retrospective study. Subject: The women who were referred to the gynecological department due to screening result of ASC-US at King Chulalongkorn Memorial Hospital, a general and tertiary referral center in Bangkok Thailand, from Jan 2008 - Dec 2012. Materials and Methods: A decision tree-based was constructed to evaluate the cost effectiveness of three follow up strategies in the management of ASC-US results: repeat cytology, triage with HPV testing and immediate colposcopy. Each ASC-US woman made the decision of each strategy after receiving all details about this algorithm, advantages and disadvantages of each strategy from a doctor. The model compared the incremental costs per case of high-grade cervical intraepithelial neoplasia (CIN2+) detected as measured by incremental cost-effectiveness ratio (ICER). Results: From the provider's perspective, immediate colposcopy is the least costly strategy and also the most effective option among the three follow up strategies. Compared with HPV triage, repeat cytology triage is less costly than HPV triage, whereas the latter provides a more effective option at an incremental cost-effectiveness ratio (ICER) of 56,048 Baht per additional case of CIN 2+ detected. From the patient's perspective, the least costly and least effective is repeat cytology triage. Repeat colposcopy has an incremental cost-effectiveness (ICER) of 2,500 Baht per additional case of CIN2+ detected when compared to colposcopy. From the sensitivity analysis, immediate colposcopy triage is no longer cost effective when the cost exceeds 2,250 Baht or the cost of cytology is less than 50 Baht (1USD = 31.58 THB). Conclusions: In women with ASC-US cytology, colposcopy is more cost-effective than repeat cytology or triage with HPV testing for both provider and patient perspectives.

Purpose: To study the prevalence of CIN2+ diagnosis in women with atypical Papaniculoau (Pap) smears to suggest appropriate management option for Thai health care. Materials and Methods: Data from all patients with liquid based cytology with human papillomavirus (HPV) testing between May 2013 - May 2016 were collected from medical records. Women with atypical cervical Pap smears were recruited. Results for age, HPV testing, HPV 16, 18, 45 and other genotypes tested, colposcopic examination and histopathological assessment were all collected. Atypical smears were defined as atypical squamous cells of undetermined significance (ASC-US) and atypical squamous cells cannot be exclude high grade squamous intraepithelial lesion (ASC-H). Results: A total of 2,144 cases were recruited. Twenty six women with ASC-US on cytology had high risk (HR) HPV detection while eight cases with ASC-H had HR-HPV (40.0% VS 72.7%, p=0.005). Among the 26 women with ASC-US cytology and positive HR-HPV, HPV type 16 (n=8, 30.8%), type 18 (n=1, 3.8%), type 45 (n=1, 3.8%) and other HPV types (n=17, 65.4%) were found. Eight women with ASC-H and positive HR-HPV demonstrated type 16 (n=6, 75%) and other HPV types (n=2, 25%). Fifty seven women with ASC-US had normal colposcopy, CIN1 and CIN2+ at percentages of 80.7 (46/57), 14.0 (8/57) and 5.3 (3/57), respectively. In the ASC-H group, 7 out of 10 women had normal colposcopy and three (30%) had CIN2+ results. Conclusions: In women with ASC-US cytology, immediate colposcopy is highly recommended. HPV testing can be performed if colposcopy is not an available option because there was high prevalence (5.3%) of CIN2+ in our findings. ASCCP recommendations for ASC-H that colposcopy should be performed on all ASC-H cases regardless of HPV result are thereby supported by the findings of this investigation.

Background: Minor cervical cytologic abnormalities include atypical squamous cells of undetermined significance (ASC-US) and low-grade squamous intraepithelial lesion (LSIL). Approximately 10-20% of women with minor cytologic abnormalities have histologic high-grade squamous intraepithelial or worse lesions (HSIL+). In Thailand, women with minor cytologic abnormalities have a relatively high risk of cervical cancer, and referral for colposcopy has been suggested. A triage test is useful in the selection of women at risk for histologic HSIL+ to reduce the colposcopy burden. The aim of this study was to assess the performance of high-risk HPV DNA test in triage of women with minor cytologic abnormalities in northern Thailand. Materials and Methods: All women with ASC-US/LSIL cytology who were referred to our colposcopy clinic from October 2010 to February 2014 were included. HPV DNA testing was performed using Hybrid Capture 2 (HC2). All patients received colposcopic examination. Accuracy values of HC2 in predicting the presence of histologic HSIL+ were calculated. Results: There were 238 women in this study (121 ASC-US and 117 LSIL). The HC2 positivity rate was significantly higher in the LSIL group than in ASC-US group (74.8% versus 41.0%, p<0.001). Histologic HSIL+ was detected in 9 women (7.4%) in the ASC-US group and 16 women (13.7%) in the LSIL group (p=0.141). There was no histologic HSIL+ detected among HC2-negative cases (sensitivity and negative predictive value of 100%). The performance of HC2 triage was highest among women aged >50 years with ASC-US cytology. An increase in the cut-off threshold for positive HC2 resulted in a substantial decrease of sensitivity and negative predictive value. Conclusions: HPV DNA testing with HC2 shows very high sensitivity and negative predictive value in triage of women with minor cervical cytologic abnormalities in northern Thailand. An increase of the cut-off threshold for HC2 triage is not recommended in this region.

Comparative studies in Phase III clinical trials quite often involve two or more equally important endpoints, and one cannot select primary endpoint from them. O'Brien(1984) proposed for continuous endpoints the OLS and GLS statistics as milti-variate test statistics. Pocock et al. (1987) mentioned the possibility of analyzing a mixture of data types, such as quantitative, binary and survival data types, with the OLS and GLS statistics, but the authors did not explore problems in combining several endpoints of different types. Furthermore, they did not perform a simulation study to assess the efficiencies of the OLS and GLS statistics for endpoints of a mixture of data types. In this paper, we propose the combining methods of correlated P-values for the analysis of multiple endpoints, and compare the efficiencies of this method with those of OLS and GLS statistics for a mixture of data types with a simulation study. Among the several methods of combining P-values that are more advantageous than combining of OLS and GLS statistics, method B maintains nominal significance levels and is more efficient, while method F and G have type I error rates that are larger than the specified significance levels, which might occasionally lead to a wrong conclusion.

There are 27 science education institutes for gifted education institutes in the university with support from the MSIT (Ministry of Science and ICT). Mathematics, physics, chemistry, biology, earth sciences, and information classes are given in each science education institute for the gifted. The authors developed a curriculum with components of computing thinking for information-gifted students. To determine if the curriculum is effective on the computer scientific attitude of the information gifted, TOSRA was modified and the test was then developed. Information students were educated at K university's science education institute for the gifted with the developed curriculum for one year and the computer scientific attitude of them was tested. According to the test results, there was a significant difference in the computer scientific attitude of the curriculum conducted at the institute at 0.05 level of significance. Statistically significant differences were observed in the social implications of computer science, attitudes of computer scientific inquiry, and the normality of computer technicians at the level of significance of 0.05. On the other hand, there were no significant differences in the adoption of computer scientific attitudes, the enjoyment of computer science lessons, leisure interest in computer science, and career interest in computer science.

The main purpose of the research is to illustrate the value of the spatial statistical approach to residential differentiation by providing a framework for exploratory spatial data analysis (ESDA) using a local spatial separation measure. ESDA aims, by utilizing a variety of statistical and cartographic visualization techniques, at seeking to detect patterns, to formulate hypotheses, and to assess statistical models for spatial data. The research is driven by a realization that ESDA based on local statistics has a great potential for substantive research. The main results are as follows. First, a local spatial separation measure is correspondingly derived from its global counterpart. Second, a set of significance testing methods based on both total and conditional randomization assumptions is provided for the local measure. Third, two mapping techniques, a 'spatial separation scatterplot map' and a 'spatial separation anomaly map', are devised for ESDA utilizing the local measure and the related significance tests. Fourth, a case study of residential differentiation between the highly educated and the least educated in major Korean metropolitan cities shows that the proposed ESDA techniques are beneficial in identifying bivariate spatial clusters and spatial outliers.

Statement of problem. The aims of the study were to evaluate the effect of current surface conditioning methods on the bond strength of a resin composite luting cement bonded to ceramic surfaces and to identify the optimum cement type. Material and methods. The sixty zirconia ceramic specimens(10 per group) with EVEREST milling machine and 60 tooth block were made. The zirconia ceramic surface was divided into two groups according to surface treatment: (1) airborne abrasion with $110{\mu}m$ aluminum oxide particles; (2) Rocatec system, tribochemical silica coating. The zirconia ceramic specimens were cemented to tooth block using resin cements. The tested resin cements were Rely X ARC, Panavia F and Superbond C&B. Each specimen was mount in a jig of the universal testing machine for shear strength. The results were subjected to 2-way ANOVA and Post hoc tests was performed using Tukey, Scheffe, and Bonferroni test. Results. The mean value of shear bond strength(MPa) were as follows: $$RelyXARC(+Al_2O_3),5.35{\pm}1.69$$; $$RelyXARC(+Rocatec),8.50{\pm}2.13$$; $$PanaviaF(+Al_2O_3),9.58{\pm}1.13$$; $$PanaviaF(+Rocatec),12.98{\pm}1.71$$; $$SuperbondC&B(+Al_2O_3)8.27{\pm}2.04$$; $$SuperbondC&B(+Rocatec),14.46{\pm}2.39$$. There was a significant increase in the shear bond strength when the ceramic surface was subjected to the tribochemical treatment(Rocatec 3M) in all cement groups(P<0.05). Bonding strengths of cements applied to samples treated with $Al_2O_3$ were compared; Rely X ARC showed the lowest values, whereas Panavia F cement showed higher value than that of Superbond C&B group with no statistical significance. When the bond strength of cements with of Rocatec treatment was compared, Rely X ARC showed lowest values. Overall, it was apparent that tribochemical treated Super-Bond possessed higher mean bond strength (14.46MPa; P<0.05) than that of Panavia F cement group with no significance. Conclusions. Silica coating followed silanization(Rocatec treatment) increase the bond strength between resin cement and zirconia ceramic. Panavia F containing phosphate monomer and Superbond C&B comprised of 4-META tend to bond chemically with zirconia ceramic, thus demonstrating higher bond strength compared to BisGMA resin cement. Superbond C&B has shown to have highest value of bonding strength to zirconia ceramic after Rocatec treatment compared to other cement.
