  • This study was designed to test the possibility of using a standardized lateral facial photographs as a clinical tool which produce the prediction of postsurgical soft-tissue profile changes associated with surgical correction in skeletal CIII patients. The number of the patients involved in this study were 27 in total, including 11 male patients and 16 female patients. A practical method to the utilization of presurgical photo prediction for mandibular prognathic patients has been presented. To predict postoperative facial appearance, montage photographs were superimposed on standard facial reference photos taken preoperatively. Within the limitations of its technology, postoperative predictions generated by this method were of sufficient accuracy, especially mandible and chin area, for clinical use. In addition, they provide valuable communication and diagnostic information which may be used in formulating treatment plan in cases requiring corrective orthognathic surgery. But, the lip changes were somewhat exaggerated by photo prediction. Consequently, the photo prediction seems suitable for planning profile changes in orthognathic surgery that include mobilization of one main mandibular fragment. Futher investigations are needed to determine whether changes of soft-tissues and hard-tissues are sufficiently reproducible so that more meaningful predictive values can be established.

  • The aim of this study were to establish the clinical references and guidelines for the maximum standardized uptake ($SUV_{max}$) value of pancreatic cancer, pancreatitis, and normal pancreas in $^{18}F-FDG$ PET-CT examinations for pancreatic disease. For this purpose, we performed the statistical analysis on the descriptive statistics, percentiles and inter quartiles range (IQR), normal distribution, and using the probability density function for pancreatic cancer, pancreatitis, and normal pancreas. As a result, the clinical reference of $SUV_{max}$ for the pancreatic cancer, pancreatitis, and normal pancreas was more than 3.45, 1.91 to 2.62, and less than 1.91, respectively. Also, optimal cut-off value for applying the dual time point PET-CT examination was determined to be 2.62. The results of this study are summarized as follows: first, we suggests the clinical reference and guideline for the pancreatic cancer, pancreatitis, and normal pancreas, and second, suggests a scientific approach to improve diagnostic accuracy of pancreatic disease by deviating from an approximate experience approach.

  • Background: We investigated the correlation between standardized uptake value (SUVmax), tumor size and Fuhrman grade in patients with renal cell carcinoma (RC). Materials and Methods: We retrospectively analyzed the data of 54 patients with clear cell renal cell carcinoma histopathologically diagnosed who underwent fluorine-18 fluoro-2 deoxyglucose positron emission tomography/computed tomography (F-18 FDG PET/CT) between January 2005 and March 2014. Results: Avarage tumor sizes were $5.64{\pm}1.85$, $6.85{\pm}2.24$ and $7.98{\pm}2.45$ in low, medium and high SUVmax groups, respectively. The Spearman's correlation coefficient between the tumor size and SUVmax was 0.385 (p=0.004) and between the Fuhrman grade and SUVmax was 0.578 (p<0.001). Conclusions: SUVmax appears highly correlated with tumor size and Fuhrman grade in patients with histopathologically confirmed clear cell RC. Multicenter studies are needed to provide larger series for more accurate results.

  • In this paper, we propose a method to measure the complexity of assets when a software component is constructed as a basic asset, a standardized design model is acquired, and a reusable extended asset is designed based on the standardized design model. However, each asset of our proposed asset management system consists of composite assets that combine assets of two domains. So this method can not make accurate measurements. Therefore, the complexity of the overall asset can be measured by reflecting the property value of the basic asset stored under the architecture. In conclusion, it is possible to measure the composite-complexity of a composed asset that is inversely proportional to cohesion and proportional to the cumulative sum of the associated values of each asset in the asset-related design.

  • Pentacyclic triterpenes, mainly, asiatic acid, madecassic acid, asiaticoside, and madecassoside are the active constituents of Centella asiatica. A pentacyclic triterpene enriched C. asiatica extract (PRE) was prepared and standardized to contain a total pentacyclic triterpenes not less than 65% w/w. This work was focused on determination of antiinflammatory, antioxidant, and tyrosinase inhibitory activities of PRE and its stability. The PRE exhibited a satisfactory nitric oxide inhibitory effect, with an $IC_{50}$ value of $64.6{\mu}g/mL$. In addition, the PRE inhibited tyrosinase enzyme activity with an $IC_{50}$ value of $104.8{\mu}g/mL$. In contrast, the PRE possessed only weak antioxidant activity. The PRE was stable over a period of four months when stored as a dried powder but only in a well-closed container protected from light at $4^{\circ}C$. An aqueous alcoholic solution of the PRE was stable at pH values of 5.8 and 7.0, but was not stable at a pH of 8.2. Preparations of the PRE in an aqueous solution should be performed in acidic or neutral conditions.

  • This study examines the cost and benefit (i.e., income) of the Forest Stewardship Council (FSC) rubber plantations in Thailand. The study attempts to identify the challenges to the implementation of FSC standards in rubber plantations in the country. A total of 60 rubber farmers in two Southern provinces, namely, Songkhla and Rayong, were interviewed through a standardized questionnaire to gather primary data. The study found that small-, medium- and large-sized FSC rubber plantations were worth investing in. All sizes of rubber plantations had similar values of benefit cost ratio (BCR). It was also found that the values of the discount payback period (DPP) of the three forms of FSC rubber plantations were 9-12 years, while the large rubber plantations had the highest internal rate of return (IRR) (19.0%). It implies that the large-size plantations had the highest values. The rubber farmers in the study area reported that they are facing a number of problems and hardships in implementing FSC standards, lacking knowledge and understanding of FSC, especially for preparing documentation. Therefore, the Thai government should take proper policy initiatives to remove all the problems and barriers in implementing FSC standards for the sustainable rubber production in the country.

  • In order to examine the changes in the appearance properties and the post-adhesion appearance properties of Hanji yarn blended fabrics : 100% Hanji yarn fabric, two kinds of cotton / Hanji yarn blended fabrics and 100% cotton fabric, were selected and fused with three kinds of interlinings. After fusing, changes of standardized KES values were examined. 1. W/T, B/W of Hanji yarn blended fabrics was higher than that cotton fabric. WC/W, 2HB/W, 2HB/B, and 2HG/G values of Hanji yarn blended fabrics are lower than cotton fabric. This means that the Hanji yarn was mixed, shape retention, wrinkle recovery was improved, and the drape property was lowered. 2. After fusing, W/T, shape retention, wrinkle recovery of Hanji yarn blended fabrics increased, and WC/W values of Hanji yarn blended fabrics decreased. The wrinkle recovery property of Hanji yarn blended fabrics were improved; however, the 2HG/G value of Hanji yarn fabric increased due to fusing, and the wrinkle recovery property of Hanji yarn fabric decreased. 3. In the selection of adhesive core, I1 adhesive core is excellent in terms of shape stability and wrinkle recovery; however, an I3 adhesive core is recommended for drape and silhouette formation. When the fabric of the adhesive core was PET, it was found to penetrate better between the fabrics during adhesion than the case of cotton fabrics.

  • This study systematically reviewed the role of diffusion-weighted imaging (DWI) in the assessment of molecular prognostic biomarkers in breast cancer, focusing on the correlation of apparent diffusion coefficient (ADC) with hormone receptor status and prognostic biomarkers. Our meta-analysis includes data from 52 studies examining ADC values in relation to estrogen receptor (ER), progesterone receptor (PgR), human epidermal growth factor receptor 2 (HER2), and Ki-67 status. The results indicated significant differences in ADC values among different receptor statuses, with ER-positive, PgR-positive, HER2-negative, and Ki-67-positive tumors having lower ADC values compared to their negative counterparts. This study also highlights the potential of advanced DWI techniques such as intravoxel incoherent motion and non-Gaussian DWI to provide additional insights beyond ADC. Despite these promising findings, the high heterogeneity among the studies underscores the need for standardized DWI protocols to improve their clinical utility in breast cancer management.

  • The objective of this research is to the enhance the color function of work clothing : to research and analyze the hue and tone of work clothing colors to be used for machinery and heavy industries in national industrial complexes, Through this research, the color using problems which related with safety workers will be revealed. For this project, total 42 sets of work suits were sampled from 12 different companies in the machinery and construction industries in the national industrial complexes of Gyeongsang Namdo Province and 16 sets of work suits currently being sold in the market. The collected work suits samples were classified according to item types and design. Color measurements were taken thus: After calibration according to ASTM D1729 specifications of standardized configuration settings to match standardized luminous source D65(Daylight 6500K) in color cabinet BOTECK SuperLight-VI, the RGB values of the work suits were calculated using PANTONE Color Cue TX. The RGB values of the colors thus derived were converted into V/C values using the Munsell Conversion 9.0.6 and analyzed with Munsell's 10-color system and PCCS. The results were presented according to Munsell's color wheel and color and brightness distributions were expressed in table form, as well as presented as a tone map. Following analysis, color hue distribution was found to be concentrated around PB, and brightness distribution toward the low end and mid range of the scale. Saturation values were distributed mostly around the low end of the scale. Following color tone analysis according to PCCS, it became apparent that colors were mainly distributed around dkg, ltg, and g, at low- and mid-brightness and low-saturation. Therefore, it may be concluded that colors used in work suits in the machinery and heavy industries are mainly cool colors, at low- and mid-brightness and low saturation. It is conjectured that such colors were applied uniformly in the workplace in order to serve certain functions, such as concealment of stains and contamination. Therefore, it follows that the utilization of colors, among other functions served by working clothings, must be taken into consideration in order to enhance safety and efficiency.
