title: Son Preference and Human Capital

description: In our model, decisions about the quantity and quality of children are interdependent and are influenced by a son preference. A son preference substantially widens the gap between the quality of female and male children, and increases the possibility of having more children to realize this preference. An increase in the level of son preference lowers the average level of education, especially for female children, while for households with a son preference, having a female birth at each birth order significantly increases the probability of having more children, with a magnitude which is much larger than that suggested in Dahl and Moretti (2008). More interestingly, once such households have a son, there is a significant reduction in that household’s likelihood of having more children. Furthermore, our findings have established the causal effect of a son preference on the quantity and quality of children within a family. <br>

title: Physical properties of recycled ABS blended with virgin ABS

description: The objective of this research is the investigation of recycled ABS which was reused. This work will be used as information for the plastic manufacturing industry. The study was separated into two cases. First, the regrind from injection manufacturing process 1[superscript st] – 6[superscript th]recycled will be investigated and the physical properties of each recycled ABS will be studied. Aging condition was carried out at 90 degree celsius 72 hrs in order to simulate one to two years of actual use. It was found that increasing number of generations has effect on the physical properties such as, melt flow index slightly decreases, impact strength clearly decreases, elongation at break decreases, flexural strength and flexural modulus and glass transition temperature increase. Degradation of polymer from the manufacturing process will transform the molecular structure such as viscosity, mechanical properties etc. Consequently, the sample was blended between virgin with 6[superscript th] recycled ABS to improve the physical properties. Second, the repelletized resin obtained from 6[superscript th] recycled ABS was blended with the ratio of 0, 20, 40, 60, 80 and 100% by weight of virgin material. It was found that increasing quantity or ratio of repelletized resins has effect on the physical properties such as, melt flow index slightly decreases, impact strength clearly decreases, elongation at break decreases, flexural strength and modulus increase and glass transition temperature increases.

title: Some properties of hypermodules over Krasner hyperrings

description: A system (R,+,.) is said to be a Krasner hyperring if (i) (R,+) is a canonical hypergroup, (ii) (R,.) is a semigroup with zero 0 where 0 is the scalar identity of (R,+) and (iii) x.(y+z)=x.y+x.z and (y+z).x=y.x+z.x for all x,y,z [is an element of a set] R. A hypermodule over a Krasner hyperring R is a canonical hypergroup M, for which there is a function (r,m) [right arrow]rm from RxM into M such that for all r, r[subscript 1], r[subscript 2] [is an element of a set]R and m, m[subscript 1],m[subacript 2] [is an element of a set] M, (i) r(m[subscript 1]+m[subscript 2])=rm[subscript 1]+rm[subscript 2], (ii) )(r[subscript 1]+r[subscript 2])m=r[subscript 1]m+r[subscript 2]m , (iii) (r[subscript 1].r[subscript 2])m=r[subscript 1](r[subscript 2]m) and (iv) 0[subscript r]m=0[subscript M]. In this research, various elementary properties of modules over rings are generalized to properties of hypermodules over Krasner hyperrings and some concrete examples of hypermodules over Krasner hyperrings are given by considering among the collection of all multiplicative interval semigroups joining 0 on the system of real numbers and some hyperoperations. Moreover, we give a definition of projective hypermodule which is parallel to the definition of projective module in module theory and study some related properties.

title: Phosphoproteins from lung cancer cell A549

description: Lung cancer is the leading cause of death after liver cancer but it trends to be increased because it is hard to detect the symptoms of a disease in the first stage. Survival rate of the patient is up to the stage of the cancer. Researcher had tried to develop the methodologies for early detection of cancers. Proteomic analysis technique is selected. This research aimed to understand the expression of proteins from lung cancer cell line (A549) and compare with normal lung fibroblast cell line (MRC-5). The phosphoproteins were the major target of investigation by using proteomic analysis technique. The results were indicated that there were several proteins which present and absent in lung cancer cell line. Some proteins were difference in term of quantitation. The most of proteins which over-expressed in lung cancer cell line (A549) were phosphoproteins such as Lamin AC 70 kDa, Aldehyde dehydrogenase, α-enolase, Glyceraldehydes-3-phosphate dehydrogenase, Pyruvate kinase, Peroxiredoxin. Moreover some proteins were expressed only in lung cancer cell line (A549) such as Heterogenous ribonucleoprotein A1, Heterogenous ribonucleoprotein H1, Nuclear corepressor KAP1, Transketolase and Cytokeratin18. Furthermore, Chaperonin which is phosphoprotein was found. This protein functions on protein interaction and protein conformation. The over-expression of this protein in cells may cause abnormality of protein conformation and lead to early stage of cancer. Then this protein may be used as biomarker of lung cancer for early detection and clinical prognosis. Further studies on this topic are required.

Study designs: Randomized controlled trial and economic analysis. Setting: Minor Operative room and outpatient surgical clinic, Department of Surgery, Bangkok Metropolitan Administration Medical College and Vajira hospital. Research Methodology: 88 patients, who indicated for surgical removal of benign skin or subcutaneous lesion, were computed randomly assigned into two groups: 2-octylcyanoacrylate for wound closure (N = 44) and absorbable subcuticular suture for wound closure (N = 44). The wound score was used for evaluation in 7th day postoperative by independent professional observers. The cost-effectiveness analysis also performed alongside with trial. Results: 2-octylcyanoacrylate had wound closure evaluation score, wound approximation (9.93 ± 0.34 VS 8.98 ± 2.35, p = 0.002, 95% CI 0.22-1.68), wound inflammation (9.86 ± 0.35 VS 8.33 ± 2.47, p &lt; 0.001, 95% CI 0.76-2.29), wound epithelization (9.83 ± 0.44 VS 8.76 ± 2.48, p = 0.018, 95% CI 0.30-1.84), wound closure time (104.09 ± 14.40 VS 227.33 ± 39.16, p &lt; 0.001, 95% CI 111.30-136.43) better than absorbable subcuticular suture with statistically significant. The 2-octylcyanoacrylate had better cost-effectiveness analysis than absorbable subcuticular suture. Conclusion: 2-octylcyanoacrylate is effectiveness for surgical incision wound closure comparing with absorbable subcuticular suture.

title: The regulation of osteopontin in stress-induced human periodontal ligament cells

description: Mechanical stress such as orthodontic forces can produce mechanical damage and inflammatory reaction in the periodontium. Osteopontin (OPN) is a multifunctional cytokine, function as a chemotactic factor and enhance the spreading and the attachment of osteoclasts to the bone surface. This study aimed to examine the influence of mechanical stress on the expression and regulation of OPN as well as the signaling pathway involved in human periodontal ligament (HPDL) cells. The in vitro mechanical stress was generated by continuous compressive force to HPDL cell culture, the expression of OPN mRNA and protein was examined by reverse transcription-polymerase chain reaction and Western analysis, respectively. The application of inhibitors was used to investigate the involved mechanism. The results of this study demonstrated the increased of OPN in a force dependent manner in both mRNA and protein levels. Interestingly, the increased of receptor activator of nuclear factor-kappa B ligand (RANKL) was also observed. Application of indomethacin could abolish the induction of RANKL but not that of OPN, suggesting the cyclooxygenase-independent mechanism for stress-induced OPN expression. The upregulation of OPN was diminished by Rho kinase inhibitor suggesting of the involvement of Rho kinase pathway involved in this mechanism. The condition media (CM) collected from stress-induced HPDL cell also increased OPN expression similar to the direct stress application. Application of suramin and NF449, a purinergic P2 receptor inhibitor, abolished both stress-induced and CM-induced OPN expression, indicating the involvement of nucleotides and P2 receptor in the inductive mechanism. In addition, the increase of adenosine 5'-triphosphate (ATP), the universal nucleotide ligand of P2 receptor family, was also found in CM after stress stimulation and the application of exogenous ATP also induced OPN expression via Rho kinase pathway. In the conclusion, mechanical stress affects OPN expression in HPDL cells by stimulating the releasd of ATP into the medium, subsequently, ATP acts through P2 receptor located at cell surface, and then activated Rho kinase pathway. The increase of OPN participates in clinical alveolar bone resorption and remodeling by inducing the migration and the attachment of osteoclasts.

title: Biosynthesis of phytosterols in cell suspension cultures of Croton Stellatopilosus

description: This study aimed to use the techniques of feeding experiments to understand the biosynthetic process of terpenoids and phytosterols with respect to their origin of isoprene units in Croton stellatopilosus cell suspension cultures. Feeding experiments with labeled glucose was first optimized for feeding conditions by using radioactively labeled [1-[superscript 14]C]glucose followed by monitoring its radiolabel uptake. The preliminary results showed that the highest incorporation of the labeled glucose occurred after 4 days of the feedings. Under the optimized conditions, [1-[superscript 13]C]glucose and [2-[superscript 13]C]sodium acetate were then fed into the cell suspension cultures of C. stellatopilosus. [beta]-Sitosterol and stigmasterol, the two major phytosterols produced, were isolated and their [superscript 13]C-labeling patterns elucidated using quantitative NMR spectroscopy. Analysis of the [superscript 13]C-enrichment patterns revealed that the components of all isoprene units of the phytosterols were supplied exclusively from the mevalonate pathway. No isoprene units originated from the alternative deoxyxylulose phosphate (DXP) pathway were detected in this study. Transmission electron micrographs (TEM) showed that there were different developmental stages of chloroplasts in different C. stellatopilosus tissues. In leaf, the chloroplasts were fully developed in palisade cells, the green callus contained a few chloroplasts with partial development, whereas no chloroplasts were found in the suspension cultured cells. Molecular analysis on the transcription level of these different types of tissues by using semi-quantitative RT-PCR technique revealed that the three genes (dxs, dxr and ggpps) involved in the isoprenoid biosynthetic route of the DXP pathway were strongly expressed in the plant leaf and green callus culture but rarely expressed in the suspension culture. This study indicated that the operation of either the DXP pathway or MVA pathway for the isoprene formation in C. stellatopilosus is dependent upon types of cultures and ability of chloroplast-forming cells in the tissues of C. stellatopilosus.

title: Estimating the cost function and unit costs of public hospitals in Thailand

description: Health expenditure in Thailand has escalated over the past decades. This trend has been prominent in the public spending, where its proportion over total health expenditure (THE) has been increasing particularly after the implementation of the universal coverage (UC) scheme. Hospitals consume the highest proportion of health resources, which exceeds 60% of total health spending, and so have been playing a significant role in the escalation of THE. Due to difficulties in obtaining data from private hospitals, this study aims to analyse the cost structure and characteristics of public hospitals in Thailand. The first component estimated the hospital cost function using 704 community and provincial hospitals in 2006. The second component developed an econometric model to estimate the unit costs of hospital services by obtaining 23 sample data from past studies between 1998−2003. Translog function was assumed for the estimation of the cost function. The results favoured the short-run cost function over the long-run. The major determinants of hospital costs included inpatient services and input prices, except for medical doctors. The proportion of UC outpatients was identified to shift-up the cost level of hospitals. UC seems to be one of the cost escalation factors of hospitals. From the estimated cost function parameters, diseconomies of scale for both community and provincial hospitals were identified which suggest the down-sizing of hospitals. Partial economies of scope between outpatient and inpatient services was identified suggesting that a stand-alone outpatient clinic would result in an increased unit cost. The opposing effects of scale and scope economies meant that the optimum size and service mix of hospitals should be identified by striking the balance between these two factors. The econometric model developed to estimate the unit cost ratio between outpatient and inpatient services enables the estimation of unit costs from full costs. Unit cost simulations revealed an average ratio between outpatient and inpatient unit costs of 1:13 for community hospitals, and 1:28 for provincial hospitals. Whilst the former approximates the current practice of 1:14 used by the Ministry of Public Health, the latter deviates significantly from the current practice of 1:18. Further studies are required to confirm the accuracy of the ratio.
