The purpose of this study is to evaluate the current inter-expert agreement of Sasang Constitution Medicine (SCM), to expand the current knowledge on the causes of imperfect inter-expert agreement, and to explore possible solutions for improving inter-expert agreement. A literature search was conducted to gather data on the studies on diagnosis of SCM. The 127 articles included in this analysis had a mean 4.1 publications per year, 56.0% published in the Journal of Sasang Constitutional Medicine between the year of 1987 and 2017. SCM specialist participated in 96.3% of all the expert judgment cases. Inter-expert agreement was reported in 14.8% of the cases that had two or more experts. We recommend that expert panels integrate the results of current status of diagnostic consensus into guideline development and strengthen expert education and training with the aim of improving SCM diagnostic accuracy.

Purpose - This paper examines whether the imposition of countervailing duties by the United States on undervalued foreign currency is legally consistent with the WTO's SCM Agreement. Design/methodology - The study uses a methodology that involves analyzing relevant WTO agreements, prior panel reports, Appellate Body decisions, and other legal documents. Findings - The findings suggest that to impose countervailing duties, certain legal requirements must be met, including financial contribution, benefit, and specificity. The paper also notes that when calculating the benefits of undervalued foreign currency, losses from import activities due to currency undervaluation must be considered. Additionally, classifying all exports to the US under specific industries or business groups is likely to be inconsistent with the SCM Agreement. Originality/value - Even the US countervailing measures on exchange rate subsidies may not comply with WTO regulations due to incorrect calculation of benefits and a lack of specificity, however, it suggests that when intervening in the foreign exchange market, the measures should aim to achieve only minimum policy goals.

Objectives In Sasang Constitutional medicine(SCM), it is an important factor to assess the degree of cold/heat and healthy status. We purposed to check the agreement among the experts on the assessment of cold/heat and healthy status. Methods Six SCM experts and 10 healthy volunteers were recruited for this study. The SCM experts had an interviewed with each volunteer in the similar condition like that of the actual clinic. And then the expert evaluated each volunteer's cold/heat and healthy status. Intraclass correlation coefficient(ICC) was used to measure the interrater reliability and interrater agreement among the experts. Results Two volunteers are excluded due to the missing data, therefore eight persons' data (3 males and 5 females) were included in our analysis. The mean of age and BMI are 21.73(${\pm}2.32$) and 29.63(${\pm}4.66$), respectively. In health status, cold status and heat status, the ICC was 0.789, 0.904, 0.925, respectively. Conclusions We found that the assessment of cold/heat and healthy status was continued reliable among SCM experts. The assessment of cold/heat status was more consistent than the assessment of healthy status.

Technology research and development (R&D) expenditures have increased as most countries recognize that technological innovation is a significant factor for continued economic growth. R&D subsidies by governmental entities were permitted in accordance with the Subsidy and Countervailing Measure (SCM) Agreement under the World Trade Organization (WTO) system. However, according to Article 31 of the SCM Agreement the provision for R&D subsidies have been terminated as of January 2000 and legal disputes over R&D subsidies are likely to increase. The aircraft industry has been the only industry where R&D subsidies have become an issue under the WTO. This paper examines international trade disputes within the aircraft industry in regards to measures by Canada and bilateral disputes between the U.S. and the European Communities (EC). In these cases, various R&D subsidies on civil aircraft are found to be inconsistent with WTO rules. This study summarizes the WTO decisions on various R&D subsidies disputed in the aircraft cases and examines the type of R&D subsidies found to be inconsistent (or consistent) with the WTO to provide guidelines for current and future R&D subsidy policies in high-tech industries. The Canada-Aircraft case indicates that R&D subsidies directly targeted towards near market R&D projects with a high export potential will likely be in violation of current WTO rules. Furthermore, findings from the EC-Aircraft and the U.S.-Aircraft cases suggest that the forms (or the methods) of R&D subsidy distribution were not a sufficient condition for the WTO ruling; instead, what ultimately mattered was whether and specifically to whom the benefits of the R&D subsidies are conferred by the government entities.

To look at Korea trade environment, as increasing the quantity of goods transported in North-East Asia and deepening national competitive, information-oriented logistics environment is needed. That means it is automated work process and can provide value-added service. To do this, logistics business can be efficiently handled through "Electronic Means for the Clearance of Ships" and electronically data processing. Also, by increasing the risk of international terrorism, regulation regarding to logistics security has strengthened around the advanced country, such as USA and EU, etc. or international organization, such as IMO, ISO, etc.. Furthermore, because trade and logistics environment is changing and security becomes more important in logistics area, movement or status information of goods within the port or in entry in/out becomes more and more be needed in real time. In case cross-border logistics activities, international cooperation or agreement between countries is very important. However, different opinions much happened on defining the interface. If to follow one format or type using at a specific country or organization, it was occurred to difficulty in respect of interoperability as well as additional costs or time. Therefore, this paper proposes common interface model to exchange information for the efficient global SCM for using by the output of Korea R&D project, "National Logistics Standardization System Development".

The adsorption of Cs-137 and Sr-90 onto kaolinite in prescence of major groundwater cations (Ca2+, K+, Na+) with different concentrations was simulated by using triple-layer surface complexation model (TL-SCM). The site density (8.73 sites/nm2) of kaolinite used for TL-SCM was calculated from it's CEC and specific surface area. TL-SCM modeling results indicate that concentrations dependence on 137Cs and 90Sr adsorption onto kaolinite as a function of pH is best modeled as an outer-sphere surface reaction. This suggests that Cs+ and Sr2+ are adsorbed at the $\beta$-layer in kaolinite-water interface where the electrolytes, Nacl, KCl and CaCl2, bind. However, TL-SCM results on Sr adsorption show a discrepancy between batch data and fitting data in alkaline condition. This may be due to precipitation of SrCO3 and complexation such as SrOH+. Intrinsic reaction constants of ions obtained from model fit are as follows: Kintcs=10-2.10, KintSr=10-2.30, KintK=10-2.80, KintCa=10-3.10 and KintNa=10-3.32. The results are in the agreement with competition order among groundwater ions (K+>Ca2+>Na+) and sorption reference of nuclides (Cs-137>Sr-90) at kaolinite-water interface showed in batch test.

In this study, an approach designed to compute high temperature friction coefficients for SCM 435 steel through a pilot hot rolling test and a finite element analysis, is proposed. Single pass pilot hot flat rolling tests with reduction ratios varying from 20 to 40% were carried out at temperatures ranging from 900 to $1200^{\circ}C$. In the proposed approach, the friction coefficient is calculated by comparing the measured strip spread and the roll force with the simulation results. This study showed that the temperature and reduction ratio had a significant influence on the friction coefficient. As both material temperature and reduction ratio become higher, the friction coefficient increases monotonically. This finding is not in agreement with the Ekelund model, which is widely used in the analysis of the hot rolling process. In the present work, the friction coefficient at a reduction ratio of 40% was found to be 1.2 times greater than that at a reduction of 30%. This higher friction coefficient means that an increment of the roll thrust force is expected at the next stand. Therefore, a roll pass designer must understand this phenomenon in order to adjust the reduction ratio at the stands while keeping the driving power, the roll housing structure and the work roll strength within the allowable range.

Forging of internal involute gears with alloy steel has been analyzed by means of upper bound method. Kinematically admissible velocity fields for forging of internal gear were proposed. It was assumed that the shape of free flow surface during forging operation is a straight line perpendicular to the plane of symmetry. Using the suggested velocity fields, forging loads and relative pressures were calculated by numerical method. Consequently forging die should be successfully designed without fracture or failure during forging operation. Experiments were carried out with the designed die and SCM415 alloy steel as billet material. The calculated loads were compared with experimental one and they are in good agreement with experimental inspections. As a result, the calculated solutions would be useful to predict the loads and the designed die is suitable for forging of internal involute spur gear with alloy steel. The forged gear is measured to be KS 4 class and its class should be improved by subsequent working such as shaving after forging operation.

A cross-sectional study was undertaken to report prevalence and to identify risk factors of subclinical mastitis of dairy cattle in Sylhet district of Bangladesh. Among 325 dairy farms of the district 12 farms(3.7%) were selected conveniently for this study. All the dairy cows of the 12 farms were selected for sample collection. Fresh milk samples from each of the selected dairy cows were collected aseptically in separate sterilized test tube as RF, RH, LF and LH quarter of the udder. Rapid modified White Side Test(WST) was used to detect subclinical mastitis(SCM). Results of WST and data derived from filled in questionnaire were entered in Microsoft Excel 2003 and transferred to $STATA^{(R)}$, version 8.0/Intercooled(Stata Corporation, Texas, USA, 2003). The overall prevalence of SCM and its distribution in different categories of variables in cow and their exact binomial 95% confidence intervals were calculated in $STATA^{(R)}$. Simple bivariable associations among independent variables were investigated by $x^2$ test in $STATA^{(R)}$. Multiple logistic regression analysis with backward elimination method was used to identify risk factors of SCM. To identify significant variation in quarter SCM, linear regression analysis was performed after arcsine transformation of the data. The overall prevalence of SCM found in this study is 54%. Dairy cows with teat lesions had significantly increased SCM(OR=12342, P value=0.000, 95% CI=762, 199798) than others without teat lesions. The Holstein Friesian X Jersey X Sahiwal breed has significantly decreased(OR=0.18, p=0.03, 95% CI 0.04, 0.85) SCM than other breeds. The prevalence of SCM found in this study is in agreement with others. The injury in the teat increases the probability of getting infected with microbes and thereby mastitis. If the prevalence of teat lesion can be decreased the probability of subclinical mastitis will also be decreased. The negatively associated Holstein Friesian X Jersey X Sahiwall breed may help in planning mastitis control program if this finding can be validated by a more powerful case-control or cohort study design.
