Analysis of the data concerning 525 middle and high school students showed that positive affect correlated positively with cognitive reappraisal strategy and with self-control but correlated negatively with expressive suppression strategy. Negative affect correlated positively with expressive suppression strategy and negatively with self-control. The group of higher positive and higher negative affect was higher than the group of lower positive and lower negative affect in cognitive reappraisal strategy. The group of higher positive and higher negative affect was higher than the group of higher positive and lower negative affect in expressive suppression strategy. The group of higher positive and lower negative affect was higher than the group of higher positive and higher negative affect in self-control.

A number of recent studies have contributed to an increased understanding of how and why workers feel bound to their unions. However, by now there has been limited theoretical works on the various forms that union membership can take. Thus, the goal of this study is to develop the types of union membership. To develop the types of union membership, I used the ideological and instrumentalitic concepts. The types of union membership are identified as follows: Positive free agents (${\Leftrightarrow}$ Negative free agents) have low levels of both positive (negative) instrumentality and positive (negative) ideology. If positive (negative) instrumentality is high and positive (negative) ideology low, this group may be labeled Instrumentals (${\Leftrightarrow}$Disgruntled). Expressives (${\Leftrightarrow}$Antagonizers) have low levels of positive (negative) union instrumentality and high levels of positive (negative) ideology. Those who have high levels of both positive (negative) ideology and positive (negative) instrumentality have been called Identifiers (${\Leftrightarrow}$Opponents). Variables related to union instrumentality, and union ideology were investigated: (1) the personal characteristics of individual members, (2) the employing organization, (3) the union characteristics, (4) the economic environment, (5) the labor relations climate.

A sign pattern is a matrix whose entries belong to the set {+, -, 0}. An n-by-n sign pattern ${\mathcal{A}}$ is said to allow an eventually positive matrix or be potentially eventually positive if there exist at least one real matrix A with the same sign pattern as ${\mathcal{A}}$ and a positive integer $k_0$ such that $A^k>0$ for all $k{\geq}k_0$. Identifying the necessary and sufficient conditions for an n-by-n sign pattern to be potentially eventually positive, and classifying the n-by-n sign patterns that allow an eventually positive matrix are two open problems. In this article, we focus on the potential eventual positivity of broom sign patterns. We identify all the minimal potentially eventually positive broom sign patterns. Consequently, we classify all the potentially eventually positive broom sign patterns.

This research is looking for the relation between the positive psychology of would-be child teachers and leadership and that's influence. The researchers examined positive psychology and leadership with 330 would-be teachers(13 boys, 317 girls) located in Gwang-Ju and the Jeonnam Region. Questionnaire was used to measure would-be teachers. The collected data analyzed the positive psychology of would-be teachers and leaders, including sub-factors for mean(M), standard deviation(SD) and Pearson product-moment correlation according to subject for inquiry. Then regression analysis through SPSS WIN 17.0 for checking the effects of the would-be child teachers's positive psychology with their leadership skill was used. The result of the research was that the positive psychology of would-be child teachers and leadership of the product-moment correlated in all areas. Especially the most influence on positive psychology is the ability of human relationship among leadership sub-variables, and the relation between positive psychology and leadership are very important for making positive changes in society. This implies that there is a need for more educational sponsorship regarding positive psychology and leadership for would-be child teachers.

Objective: Pituitary adenomas are common neurological lesions believed to account for 10% to 15% of all primary brain tumors. There can be diagnostic confusion due to discordance of the preoperative endocrine and the postoperative immunohistochemical diagnosis. In this study, the rate of discordance between preoperative and postoperative findings and their clinical implications were investigated. Methods: From March 2005 to March 2006, 26 patients who underwent surgery for a pituitary adenoma were enrolled in this study. The preoperative pituitary hormone level and postoperative immunohistochemical results were compared and analyzed. Results: The median age of the patients was 38 years [range 15-66 years]. The male to female ratio was 8 to 18. The endocrine evaluation showed 16 hormonally-active and 10 hormonally-inactive adenomas. The immunohistochemical findings showed : 13 prolactin-positive, 1 GH-positive, 1 FSH-positive, 8 pleurihormone-positive and 3 stain-negative adenomas. The percentage of discordance observed between the preoperative endocrine and postoperative immunohistochemical diagnosis was 54%. Nine of 10 endocrine non-functioning adenomas showed : 3 PRL positive, 1 GH positive, 2 PRL+GH positive, 1 TSH+FSH positive, 1 FSH+ACTH+PRL positive and 1 FSH+LH+PRL positive adenomas by immunohistochemistry. Three endocrine PRL+GH secreting adenomas showed 2 PRL positive and 1 FSH+GH positive by immunohistochemistry. One endocrine PRL secreting and 1 GH secreting adenoma showed 1 PRL+ TSH positive and 1 GH+PRL positive by immunohistochemistry, respectively. The diagnosis of the other 12 pituitary adenomas showed concordance. Conclusion : The results of this study showed 54% discordance rate between the preoperative endocrine and postoperative immunohistochemical diagnosis for pituitary adenomas.

본 연구는 긍정정서와 긍정정서 반응 양식이 안녕감에 미치는 영향을 탐색하고자 하였다. Fredrickson(1998)의 '확장-구축 이론(Broaden-and-Build theory)'에 기반하여, 긍정정서와 긍정정서 반응 양식이 안녕감의 변화와 유의하게 관련이 되고, 안녕감의 변화에 이들 변인이 호혜적으로 영향을 미칠 것이라고 가정하였다. 단기종단연구를 통해 학부생과 대학원생 147명을 대상으로 긍정정서와 긍정정서 반응 양식, 안녕감을 측정하였고, 참가자들의 안녕감 기저선을 통제하여 변인간 관계를 확인하였다. 연구 결과, 긍정정서와 긍정정서 강화하기는 안녕감의 증가를 유의하게 예측하였으나, 긍정정서 가라앉히기는 안녕감을 유의하게 예측하지 못하였다. 또한 긍정정서와 안녕감의 관계를 긍정정서 강화하기가 부분적으로 매개하였으며, 긍정정서 강화하기와 안녕감의 관계를 긍정정서가 완전 매개하는 것으로 나타났다. 이로써 긍정정서와 긍정정서 강화하기는 서로 영향을 주고 받음으로써 안녕감을 증진시키는 호혜적 관계임을 확인하였다. 이러한 결과를 바탕으로 상담 실제에 대한 시사점과 연구의 제한점을 논하였다.

Background: The performance of combined testing visual inspection with acetic acid (VIA) and cervical cytology tests might differ from one setting to another. The average estimate of the testing accuracy across studies is informative, but no meta-analysis has been carried out to assess this combined method. Objective: The objective of this study was to estimate the average sensitivity and specificity of the combined VIA and cervical cytology tests for the detection of cervical precancerous lesions. Materials and Methods: We conducted a systematic review and a meta-analysis, according to the Cochrane Handbook for Systematic Review of Diagnostic Test Accuracy. We considered two cases. In the either-positive result case, a positive result implies positivity in at least one of the tests. A negative result implies negativity in both tests. In the both-positive case, a positive result implies having both tests positive. Eligible studies were identified using Pubmed, Embase, Website of Science, CINHAL and COCRANE databases. True positive, false positive, false negative and true negative values were extracted. Estimates of sensitivity and specificity, positive and negative likelihood (LR) and diagnostic odds ratios (DOR) were pooled using a hierarchical random effect model. Hierarchical summary receiver operating characteristics (HSROC) were generated and heterogeneity was verified through covariates potentially influencing the diagnostic odds ratio. Findings: Nine studies fulfilled inclusion criteria and were included in the analysis. Pooled estimates of the sensitivities of the combined tests in either-positive and both-positive cases were 0.87 (95% CI: 0.83-0.90) and 0.38 (95% CI: 0.29-0.48), respectively. Corresponding specificities were 0.79 (95% CI: 0.63-0.89) and 0.98 (95% CI: 0.96-0.99) respectively. The DORs of the combined tests in either-positive or both-positive result cases were 27.7 (95% CI: 12.5-61.5) and 52 (95% CI: 22.1-122.2), respectively. When including only articles without partial verification bias and also a high-grade cervical intraepithelial neoplasia as a threshold of the disease, DOR of combined test in both-positive result cases remained the highest. However, DORs decreased to 12.1 (95% CI: 6.05-24.1) and 13.8 (95% CI: 7.92-23.9) in studies without partial verification bias for the combined tests in the either-positive and both-positive result cases, respectively. The screener, the place of study and the size of the population significantly influenced the DOR of combined tests in the both-positive result case in restriction analyses that considered only articles with CIN2+ as disease threshold. Conclusions: The combined test in the either-positive result case has a high sensitivity, but a low specificity. These results suggest that the combined test should be considered in developing countries as a primary screening test if facilities exist to confirm, through colposcopy and biopsy, a positive result.
