Background: Cholangiocarcinoma (CCA), a major problem of health in Thailand, particularly in Northeastern and Northern regions, is generally incurable and rapidly lethal because of presentation in stage 3 or 4. Early diagnosis of stage 1 and 2 could allow better survival. Therefore, this study aimed to provide a distribution map of populations at risk for CCA in BuaYai district of Nakhon Ratchasima province, Northeast Thailand. Materials and Methods: A cross-sectional survey was carried out in 10 sub-districts and 122 villages, during June and November 2015. The populations at risk for CCA were screened using the Korat CCA verbal screening test (KCVST) and then risk areas were displayed by using Google map (GM). Results: A total of 11,435 individuals from a 26,198 population completed the KCVST. The majority had a low score of risk for CCA (1-4 points; 93.3%). High scores with 6, 7 and 8 points accounted for 1.20%, 0.13% and 0.02%. The population at risk was found frequently in sub-district municipalities, followed by sub-district administrative organization and town municipalities, (F=396.220, P-value=0.000). Distribution mapping comprised 11 layers: 1, district; 2, local administrative organization; 3, hospital; 4, KCVST opisthorchiasis; 5, KCVST praziquantel used; 6, KCVST cholelithiasis; 7, KCVST raw fish consumption; 8, KCVST alcohol consumption; 9, KCVST pesticide used; 10, KCVST relative family with CCA; and 11, KCVST naive northeastern people. Geovisual display is now available online. Conclusions: This study indicated that the population at high risk of CCA in Bua Yai district is low, therefore setting a zero model project is possible. Key success factors for disease prevention and control need further study. GM production is suitable for further CCA surveillance and monitoring of the population with a high risk score in this area.

This study was designed to investigate the effect of bone demineralization and tibia lead on blood lead in retired lead workers. Two hundred thirty five(126 females and 109 males) retired lead workers who worked in 4 different lead factories and 101 non-occupationally lead exposed subjects(51 females and 51 males) were recruited from March 2004 to October 2004. Bone mineral density(BMD) was measured at left calcaneous bone area by broadband ultrasound attenuation(BUA) method with QUS-2(Metra Biosystems Inc, USA). The BUA value transformed into T-score by WHO standard conversion criteria. Tibia bone lead was measured for skeletal bone lead with K-xray fluorescence(K-XRF) and blood lead was analyzed with flameless atomic spectrophotometer. Hemoglobin, hematocrit, serum calcium and iron were also analyzed. In addition, information for smoking and drinking status and basic personal data such as age, gender and lead exposure were also collected using questionnaire inquiry. Blood lead was correlated with tibia lead (r=0.664) and these two variables were negatively correlated with BMD in bivariate analysis. BMD showed significant main effect on the change of blood lead independent to tibia lead without any effect modification of age or gender; the one T-score unit decrease of mineral bone density made $0.43{\mu}g/dl$ increase of blood lead. On the other hand, tibia lead showed effect modification with gender on blood lead; the slope of tibia lead on blood lead in male was steeper than in female and crossed at around zero of tibia lead. In the multiple regression analysis of blood lead and tibia lead on BMD after adjustment of related covariates, only blood lead showed statistically significant effect on BMD. This study confirmed that BMD and blood lead were significantly associated. To verify the causal association of BMD on blood lead and vice versa, further longitudinal studies are needed.

Opisthorchis viverrini infection is associated with cholangiocarcinoma particularly in the cases of chronic or re-infection. This presents a serious health problem in northeastern and northern Thailand. A community base approach is required for surveillance. Therefore, in a pilot project, re-examination of O. viverrini infection was conducted in the 3 districts of Nakhon Ratchasima province, Thailand, during June and October 2015. A total of 355 participants from a 194,152 population, was selected through multi-stage sampling. O. viverrini infection was determined using modified Kato Katz thick smear technique. Participants were 229 males and 126 females, and aged ${\geq}30$ years old. Prevalence of O. viverrini infection was 2.25% (8/355 participants). O. viverrini infection was slightly higher in females (3.17%), and age group between 41-50 years (4.49%). Mueang Yang district had a highest of O. viverrini infection rate (2.82%), and followed by Bua Yai (2.48%), and Chum Phuang (1.84%), respectively. O. viverrini infection rate was increased from year 2012 to 2015 particularly in Bua Yai and Mueang Yang. These re-examinion results indicate that opisthorchiasis is still problem in community of Nakhon Ratchasima province, therefore, the provincial-wide scale is need required. Furthermore health education is need intervened in the infected group, and screening of cholangiocarcinoma is urgently concerned.

This study aims to examine the impact of service recovery in building customer loyalty through the mediating role of customer satisfaction and corporate image. This study also aims to examine the reciprocal relationship between customer satisfaction and corporate image in building customer loyalty. This study uses data from 126 consumers who have received recovery for a service failure in five logistics companies which operates in Southeast Sulawesi in Indonesia, namely; JNEs; J&T Express; Pandu Logistics; MEC; and TiKi. Data was collected using a questionnaire which was then distributed to all respondents via google form. The distribution of respondents at each logistics company provider was as follows: 19 respondents were customers of JNEs; 17 respondents were customers of J&T Express; 32 respondents were customers of Pandu Logistics; 21 respondents were customers of MEC; and 37 respondents were customers of TiKi's. The structural model developed in this study was tested using Partial Least Squared (PLS) method. The research found that service recovery has a direct effect on customer satisfaction and corporate image as positive and significant. Customer satisfaction and corporate image have a reciprocal relationship which then roles in building customer loyalty. Service recovery has an indirect effect on customer loyalty through the mediating role of customer satisfaction and corporate image.

A green spectrophotometric method for the determination of cyanide has been proposed using, a green reagent, aqueous extract of blue butterfly pea. The test tube was filled with anthocyanin rich extract (pH 6) and cyanide solution. The reaction was kept constant for 10 minutes at room temperature. The reaction mixture changed color from blue to green as the amount of CN-ions increased. The 620 nm peak intensity increased with CN concentration. Therefore, this wavelength was used for all cyanide analyses. The cyanide calibration curve had a linear range of 0.25-1.00, 1.00-4.00, and 4.00-10.00 mg/L, with a satisfactory correlation coefficient of 0.99 and a LOD of 0.57 mg/L. The recovery ranged from 8.33 to 76.94 percent, indicating that this method is inaccurate at low cyanide concentrations. The intra-day and intermediate precision relative deviations were 0.391-0.871 % and 1.112-1.583 %. An H-bond forms between the C-4 group of the B-carbonyl ring and the HCN molecule according to the B3LYP/TZVP calculation. The method is convenient for cyanide concentrations above the LOQ of 1.09 mg/L, cost-effective, and capable of reducing toxic solvents with acceptable precision. The method could also be used to detect total cyanide in biological, environmental, and industrial waste samples.

This study was conducted to investigate the effects of smoking on nutrition intake, bone mineral density and blood mineral status. The subjects were composed of two groups: 100 smokers and 100 non-smokers was used along with a questionnaire. Anthropometric measurements, dietary intakes using 24-hours recall method were compared. At twenty subjects from each group were selected, bone mineral density were measured by quantitative ultrasound and plasma mineral levels were analyzed by ICP spectrometer. The average ages of smokers and non-smokers were 23.9 and 22.8 years old, respectively. The height, weight and BMI of the smokers were no significant difference. The average numbers of smoked cigarettes were 11.8/d and the average packyear was 3.1 in the smokers. About $97\%$ of the smokers drank alcoholic beverages, while $85\%$ of the non-smokers did. The smokers tended to eat less meals and dinner meal, but drink coffee more often compared to the non-smokers. The mean daily energy intake and CPF energy intake ratio were 2184. 9 kcal and 57.2 : 13.7 : 26.4 in the smokers and 2262.6 kcal and 55.8 : 13.1 : 28.6 in the non-smokers. The smokers consumed significantly lower intake of $\beta$-carotene. There were no significant differences in bone mineral density of BUA, SOS and QUI. There were no significant differences in plasma levels of Ca, Mg, Fe and Zn. However, plasma Cu level of the smokers was significantly higher than that of the non-smokers. In conclusion, the smokers of this study showed a more undesirable dietary intake in the light of their low ,B -carotene and high alcoholic beverages, and coffee. The plasma Cu level of the smokers was higher than that of the non-smokers, showing that Cu is involved in smoking. Therefore, it could be suggested that more systematic research be conducted with respect to Cu and smoking and that increased nutrition education and guidelines for smokers are required.

Nutrition factors play an important role in the pathogenesis of osteoporosis. The purpose of this study is to investigate the relationship between nutritional status and bone mineral density of elderly women. Three hundred thirty five elderly women (over 65 years) in Asan were divided into three age groups (group 1, less than 70 y ; group 2, from 70 to 75 y ; group 3, 75 y or more). Total alkaline phosphatase and serum calcium (Ca) were analyzed using spectrophotometric procedure. Data for food and nutrient intakes were obtained by a 24-hour recall method. Bone density was measured by broadband ultrasound attenuation (BUA) using QUS-2. Age differences were tested with the X 2 test for categorical variables and with ANOVA and Tukey's test for continuous variables. Correlation was conducted to test the association between bone density and nutrient intake. The subjects in age groups 1,2 and 3 were $36.7\%$, $32.8\%$ and $30.4\%$, respectively. Height and body weight of the subjects were significantly decreased with age. Average bone density of the subjects in group 3 was lower than the other age groups. Osteoporosis determined by t-score is $17.9\%$ for group 1, $24.5\%$ for group 2 and $55.9\%$ for group 3 (p < 0.001). The serum Ca level of the subjects in group 2 was significantly lower than that of group 1 although mean values in all age groups are within the normal range. Dietary Ca intake, nutrient adequacy ratio (NAR) and index of nutrient quality (INQ) were decreased with age. Bone density was negatively correlated with age (p < 0.001), while body mass index (p < 0.01) was positively related with bone density. Although partial correlation did not reveal the significant correlation of BMD and dietary calcium after controlling for age, since calcium intake was very poor compared to sodium and phosphorous intakes, recommendation of more calcium intake for elderly women especially those over 75 years must be continuously emphasized.

In this study, greenhouse gas (GHG) reductions from bioenergy (biogas, biomass) have been estimated in Korea, 2015. This study for construction of reduction inventories as direct and indirect reduction sources was derived from IPCC 2006 guidelines for national greenhouse gas inventories, guidelines for local government greenhouse inventories published in 2016, also purchased electricity and steam indirect emission factors obtained from KPX, GIR respectively. As a result, the annual GHG reductions were estimated as $1,860,000tonCO_{2eq}$ accounting for 76.8% of direct reduction (scope 1) and 23.2% of indirect reduction (scope 2). Estimation of individual greenhouse gases (GHGs) from biogas appeared that $CO_2$, $CH_4$, $N_2O$ were $90,000tonCO_2$ (5.5%), $55,000tonCH_4$ (94.5%), $0.3tonN_2O$ (0.004%), respectively. In addition, biomass was $250,000tonCO_2$ (107%), $-300tonCH_4$ (-3.2%), $-33tonN_2O$ (-3.9%). For understanding the values of estimation method levels, field data (this study) appeared to be approximately 85.47% compared to installed capacity. In details, biogas and biomass resulting from field data showed to be 76%, 74% compared to installed capacity, respectively. In the comparison of this study and CDM project with GHG reduction unit per year installed capacity, this study showed as 42% level versus CDM project. Scenario analysis of GHG reductions potential from bioenergy was analyzed that generation efficiency, availability and cumulative distribution were significantly effective on reducing GHG.
