Cholangiocarcinoma (CCA) is a serious problem in Thailand, particularly in the northeastern region. Active surveillance in rural communities with an appropriat low-cost screening tool is required to facilitate early detection. Therefore, this study aimed to investigate the population at risk of CCA in Bua Yai district, Nakhon Ratchasima province, Northeastern Thailand using the Korat-CCA verbal screening test (KCVST) during June to October 2015. Reliability of KCVST demonstrated a Cronbach alpha coefficient=0.75 Stepwise-multiple regression showed that alcohol consumption was important for CCA screened, followed by agriculture and pesticide use, under-cooked cyprinoid fish consumption, praziquantel use, naïve northeastern people, opisthorchiasis, family relatives with CCA, and cholangitis or cholecystitis or gallstones, respectively. Population at risk for CCA was classified to low risk (63.4%), moderate risk (33.7%), and high risk (1.32%) for CCA. When CCA was screened using ultrasonography, 4 of 32 high risk participants had an abnormal biliary tract with dilated bile ducts. This study indicates that KCVST is a potential useful too which decrease the cost of large scale CCA screening.
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.

Background: Introduction of the HPV vaccine is a forefront primary prevention method in reducing the incidence of carcinogenic human papillomavirus (HPV) and cervical cancer. The Malaysia government has implemented the National HPV immunisation programme since 2010, supplying HPV vaccine free to targeted 13 year olds. This study aimed to explore the level of knowledge among mothers on cervical cancer, HPV, HPV vaccine and National HPV (NHPV) immunisation programme since its' implementation. It also assessed acceptance of mothers towards HPV vaccine being administered to their daughter, son or themselves. Materials and Methods: A cross sectional study was conducted on 155 respondents using self-administered questionnaires; conducted in December 2012 at the Obstetrics and Gynaecology Clinic in a teaching hospital in Kuala Lumpur. Respondents were selected using a multistage sampling technique. Results: A response rate of 100% was obtained. Overall, 51.0% of mothers had good knowledge, with 55% having good knowledge of cervical cancer, 54.2% for both HPV and the National HPV immunisation programme and 51.0% for the HPV vaccine. Regression analyses showed that ethnicity was associated with knowledge on cervical cancer (p=0.003) while education was associated with knowledge on HPV (p=0.049). Three factors are associated with knowledge of the National HPV immunisation programme; ethnicity (p=0.017), mothers' education (p=0.0005) and number of children (p=0.020). The acceptance of HPV vaccine to be administered among daughter was the highest at 87.1%, followed by for mothers themselves at 73.5%, and the least is for sons 62.6%. Conclusions: This study found that the overall level of knowledge was moderate. Adequate information on cervical cancer, HPV, HPV vaccination and the National HPV immunisation programme should be provided to mothers in order to increase acceptance of the HPV vaccine which can reduce the disease burden in the future.
The purpose of this study was to investigate the impact of depression, discomfort, spirituality, physical care, and opioid use on pain with terminally ill cancer patients residing in hospice units. The convenient sample of this study consisted of 41 terminally ill cancer patients at three hospice units in university affiliated hospitals. Patients were interviewed with structured questionnaires three times at predetermined intervals: admission to the hospice unit (Time 1), one week later (Time 2), and two weeks later (Time 3). The data was collected from January 1998 to January 1999 and was analyzed using ANOVA, Pearson correlation coefficient, and multivariate multiple regression. 1. The mean age of the participants was approximately 55 years old. In terms of diagnosis, lung cancer showed the highest frequency (19.5%), followed by stomach cancer and rectal cancer (17.1%). The motive of seeking hospice unit admission was control (72. 2%), followed by spiritual care (50%), and symptom relief (38.9%). 2. Regarding the type of pain felt, the highest pain frequency the participants experienced was deep pain (55%), followed by multiple pain (25%), intestinal pain (10%), then superficial (5%) and neurogenic pain (5%). For the level of pain measured by VAS, there was no significant difference among the three time points; Time 1 (5.04$\pm$2.21), Time 2 (4.82$\pm$2.58) and Time 3(4.73$\pm$2.51). 3. There was significant change seen in spirituality and physical care in each time interval. Namely, the longer the length of admission at the hospice unit, the higher the importance of spirituality (p=0.0001) and the more the physical care the participants received (p=0.01). The opioid use at the three time points showed the following frequencies : Time 1 (75.6%), Time 2 (85.4%) and Time 3 (75.6%). 4. Regarding factors influencing pain, the pain level was significantly affected by the depression level (p〈0.01) and the opioid use (p〈0.1). These results were the most significant at the two time points (Time 1 and Time 2). At Time 3 (two weeks later), the pain level was significantly affected by the depression level (p〈0.05) and the amount of physical care the participants received (p〈0.1). In conclusion, the terminally ill cancer patients had moderate pain, were generally depressed, and were treated with opioid analgesics. As approaching death, the patients received more physical care due to increased physical symptoms experienced and they had a higher perception of the importance of spirituality. Thus, health care professionals need to provide continuous care for each of them to die comfortably physically, psycho- logically, and spiritually.

Since Campbell (1990) proposed multidimensionality of job performance, unlike the single structure of traditional job performance, it has been largely classified as task performance, contextual performance, and counterproductive work behavior. The objective of this study is to validate the threecriteria currently considered major aspects of job performance, to identify different types of performance based on three dimensions, and to compare the power of personality factors among performance types. A total of 681 employees working at various organizations participated in an on-line survey. The survey included boththe exploratory and confirmatory factor analyses. A 3-factor job performance model consisting of three dimensions was also included. The relationships between performance dimensions and personality factors differedby dimensions of performance, supporting the validity of the 3-factor structure of performance.The results of the Latent Profile Analysis identified four types of performance: exemplary, moderately conscientious moderate, and conscientious, butlow.. The Multinomial logistic regression analysis showed each type differed significantly according to the predictors of personality variables. In conclusion, implications and limitations of the study were noted.

The purpose of this study was to analyze the patterns and the interrelationships for meeting guidelines of three health behaviors including physical activity(PA), sedentary behavior(SB), and dietary behavior(DB) for Korean adolescents using 2007 KYRBS(Korea Youth Risk Behavior Survey) data. A cross-sectional design was used to assess 73392 middle-high school students. PA(moderate physical activity${\geqq}$5times/week, or vigorous ${\geqq}$3times/week), SB(watching TV, computer, DVD, video, etc. < 3 hr/day), and DB(servings of fruits ${\geqq}$1 times/day, or vegetables ${\geqq}$ 3 times/day) were categorized into two levels (meeting guidelines or not). Chi-squared tests were conducted to compare the prevalence of students not meeting these three health behaviors between boys and girls, and logistic linear regression was used to determine the interrelationships of three health behaviors. Students meeting guidelines for PA, SB, and DB were 31.0%(boys 42.6%, girls 18.0%), 74.7%(boys 75.4%, girls 74.0%), and 38.5%(boys 38.6%, girls 38.4%), respectively. In addition, there were significant differences between both genders for PA and SB (PA; $x^2(1)$=35175.11, p<.0001, SB; $x^2(1)$=19.44, p<.0001). Only 10.9% of students met all three guidelines and 12.4% did not meet all three. Pattern that simultaneously did not meet PA and DB were high in both boys(27.1%) and girls(37.2%). Students who did not meet DB were at greater risk of not meeting PA(Boys; OR 1.49, 95% CI 1.43 to 1.55, Girls; OR 1.42, 95% CI 1.34 to 1.50), and not meeting SB(Boys; OR 1.41, 95% CI 1.34 to 1.48, Girls; OR 1.36, 95% CI 1.29 to 1.43) compared with students who met DB. The findings of this study supported further evidence for the need of a multiple behavior approach considering gender and interrelationships among three behaviors.
The related factors of the quality of life (QOL) in stroke patients was identified empirically. The subjects were 254 stroke patients who were discharged and taken follow-up care at the outpatient department. In this model, the physical, psychological, and social status were assumed to affect the QOL. And the social support was assumed to moderate these effects. NIH stroke state, ADL, and IADL were used to measure the physical status. Using CES-D, the psychological status was measured. The social status was defined as the job change after stroke attack. The satisfaction with the care by primary caregivers, significant others, and health professionals was measured as the social support. To identify the effect of the physical, psychological, and social status on the QOL, multiple regression analysis was carried out. The psychological and social status were found to be the significant predictors of the QOL(R2=0.27, p=0.00). Next, to identify the moderating effect of the social support, the subjects were divided into two groups, that is, the low social support group and the high social support group. It is found that the predicting variance is different between these two groups. In the low social support group, the psychological, social, and physical status predicted as much as 42% of the QOL. On the contrary, the psychological status predicted only 8% of the QOL in the high social support group. So it is concluded that the social support moderates the effects of the physical, psychological, and social status on QOL. Finally, to identify the social support which moderates those effects, the social support was divided into three classes. Each social support class was divided into the low and high social support group again. In the every class of social support, the difference between two groups was also identified. So the model of the QOL is recommended for the framework of the care for the stroke patients. Also these results support the claim that the long-term facilities for stroke patients are necessary.
Korean income data obtained from Korea Labor Panel Survey shows excessive zeros, which may not be properly explained by the Tobit model. In this paper, we analyze the data using a zero-inflated Tobit model to incorporate excessive zeros. A zero-inflated Tobit model consists of two stages. In the first stage, individuals with 0 income are divided into two groups: genuine zero group and random zero group. Individuals in the genuine zero group did not participate labor market since they have no intention to do so. Individuals in the random zero group participated labor market but their incomes are very low and truncated at 0. In the second stage, the Tobit model is assumed to a subset of data combining random zeros and positive observations. Regression models are employed in both stages to obtain the effect of explanatory variables on the participation of labor market and the income amount. Markov chain Monte Carlo methods are applied for the Bayesian analysis of the data. The proposed zero-inflated Tobit model outperforms the Tobit model in model fit and prediction of zero frequency. The analysis results show strong evidence that the probability of participating in the labor market increases with age, decreases with education, and women tend to have stronger intentions on participating in the labor market than men. There also exists moderate evidence that the probability of participating in the labor market decreases with socio-economic status and reserved wage. However, the amount of monthly wage increases with age and education, and it is larger for married than unmarried and for men than women.
Obstructive Sleep Apnea-Hypopnea Syndrome (OSAHS) is a disorder characterized by the repetitive collapse of the pharyngeal airway during sleep, which leads to oxygen desaturation, sleep fragmentation, daytime sleepiness, and increased risk for hypertension and stroke. We investigated the clinical factors related to the severity of OSAHS. Polysomnography was performed in three hundred and ninety five consecutive adult patients with clinical symptoms of obstructive sleep apnea syndrome. All patients completed the sleep questionnaire and the Epworth Sleepiness Scale before polysomnography. Patients were classified into four groups based on the severity of their polysomnographic data: Non-OSA group, characterized by Apnea-Hypopnea Index (AHI) < 5; mild OSA group, by AHI 5-15; moderate OSA group, by AHI 16-30; and severe OSA group, by AHI > 30. Neck circumference was also measured at the cricothyroid level. A total of 395 patients (336 men and 59 women) were studied. In the non-OSA group, there were 55 patients; their mean neck circumference was $39.63{\pm}4.24cm$ and mean BMI was $24.48{\pm}3.53$. In the mild group, there were 101 patients; their mean neck circumference was $41.93{\pm}3.75cm$ and mean BMI was $25.33{\pm}2.94$. In the moderated group, there were 93 patients; their mean neck circumference was $43.27{\pm}3.50cm$ and BMI was $25.90{\pm}2.88$. In the severe group, there were 146 patients; their mean neck circumference was $44.94{\pm}3.93cm$ and mean BMI was $26.81{\pm}3.76$. Men had significantly larger neck circumference than women ($Mean{\pm}SD$, $43.72{\pm}3.83$ vs $39.17{\pm}4.30$, p < 0.001), and higher AHI than women ($29.12{\pm}22.65$ vs $14.63{\pm}14.11$, p < 0.001). Multiple regression analysis revealed that neck circumference was the most significant predictor of AHI. Neck circumference and BMI were positively correlated with the severity of OSAHS. The severity of OSAHS was greater in men than in women.
A genetic study on the panicle characters in Oryza sativa was carried out by means of a 5 x 5 diallel cross. The five parental varieties were Raekyung, Yeongnamjosaeng, Nongbaek, Yushin and Honenwase. All characters were correlated positively each other, except number of kernels per primary branch. The number of secondary branches per primary branch.was the most effective factor in determining the number of kernels per panicle, the next being the number of primary branches per panicle. Regression analyses of the data of Vr/Wr indicated the presence of non-allelic gene interactions for all characters. Overdominant characters were the number of kernels per panicle, the number of primary branches per panicle, the number of secondary branches per primary branch, the number of kernels per primary branch and sum of kernels on all the tertiary branches per panicle, suggesting that the characters were more influenced by dominant effect than additive effect. However, the number of kernels per secondary branch was partially dominant where the genetic variation was due more to additive effect than to dominance effect. But after omitting the parent which had non-allelic interaction gene, the characters; the number of kernels per panicle, the number of secondary branches per primary branch, and the number of kernels per secondary branch, were partially dominant. Narrow sense heritabilities(h$^2$ N) in number of kernels per panicle and number of secondary branches were high and moderate, respectively, but those of the rest were lower. Mean squares of GCA and SCA of all characters, except SCA of the number of kernels per secondary branch, were highly significant. Effects of GCA were larger than SCA effects in all characters. Raekyung, Yushin and Nongbaek had highly positive GCA, and the best positive SCA was observed in crosses of Nongbaek x Tongillines (Raekyung, Yushin, and Yeongnamjosaeng) in all characters.
