Purpose : The aim of this study is to identify current situation and issues of outcome measures to evaluate the public health programs using traditional medicine by public health centers in Korea. Method :This study analyse and review existing data and documents related to traditional Korean medicine and health policy using contents analysis method. To collect the information on outcome measures evaluating the programmes, this study reviewed annual reports for health promotion programmes using traditional Korean medicine(HP-TKM) of Hub public health centers, as pilot public health centers, which have implemented the health promotion programmes collectively. Additionally, the review included research articles, government documents and book chapters on the topics related assessments in health promotion. Results :HP-TKM are stroke prevention education, smoke free program, health promotion according to Four Constitutional Medicine, home visiting treatment, etc. However, there are only a few studies of traditional medicine focused health promotion evaluation strategies. The benefits of health promotion programs using TKM can be categorized as non-health benefit, physiological, psychological and physical effects. To manage and monitor the intervention programmes efficiently, attention should be given to developing relevant and valid outcome measures for evaluating the programmes by government and public health center. Conclusion :Up to now, considering number of researchers, research projects undertaken or published articles and reports, within traditional Korean medicine there is a lack of capacity in research. Thus, government should pay more attention to developing relevant and valid outcome measures for evaluating the programs.

Average number of samples to signal (ANSS) and average time to signal (ATS) are the most widely used criterion for comparing the efficiencies of the quality control charts. In this study the method of evaluating ANSS and ATS values of the multivariate exponentially weighted moving average (EWMA) control charts with Markov chain approach was presented when the production process is in control state or out of control state. Through numerical results, it is found that when the number of transient state r is less than 50, the calculated ANSS and ATS values are unstable; and ATS(r) tends to be stabilized when r is greater than 100; in addition, when the properties of multivariate EWMA control chart is evaluated using Markov chain method, the number of transient state r requires bigger values when the smoothing constatnt ${\lambda}$ becomes smaller.

The purpose of this study is to provide basic data for the production of jackets with high fit by comparing and analyzing the adhesive and non-adhesive production methods of men's jackets. An analysis of the manufacturing method showcased differences between the adhesive and non-adhesive manufacturing methods in the cutting and wick attachment method, the shape and attachment method of the chest reinforcing wick, the sleeve attachment method, and the shoulder pad and sleeve reinforcing cloth attachment method. In evaluating the outfit, the overall fit of the shoulder, the fit of the chest, and the fit of the armpit were found to be high in the non-adhesive production method. In evaluating appearance evaluation, the front shoulder, chest, and sleeve overall appearance showed a high non-adhesive production method. Therefore, in order to increase the wearability of the shoulder pad and the the attachment method of the upper sleeve reinforcing cloth, the non-adhesive production method should be used, and in order to increase the overall wearability and armpit wear of the chest, the difference in the attachment method, and the reinforcement method of the armhole should be used. In addition, to increase the appearance of the jacket, non-adhesive production methods such as differences in wick attachment methods, shoulder pads, sleeve reinforcing cloth, and sleeve attachment methods should be used.

This article describes a methodology for evaluating huge aerospace R&D investments using the real options pricing method. Option pricing has been proposed as a useful approach for modeling investment in R&D. Two important features of R&D investments are that an R&D project takes time to complete and that the outcome of R&D investments is highly uncertain. This makes the analysis of R&D investments difficult. Traditional tools for project evaluation, like IRR or the NPV, are inadequate for coping with the high uncertainty. Hence, In this article I propose a log-transformed binomal lattice method, and it will show that option pricing might be an adequate framework for evaluating such types of aerospace investments.

A WTCI is an important criteria for evaluating an mount of patient's tongue coating in tongue diagnosis. However, Previous WTCI tongue coating evaluation methods is a most of quantitatively measuring ration of the extracted tongue coating region and tongue body region, which has a non-objective measurement problem occurring by exposure conditions of tongue image or the recognition performance of tongue coating. Therefore, a WTCI based on deep learning is proposed for classifying an amount of tonger coating in this paper. This is applying the AI deep learning method using big data. to WTCI for evaluating an amount of tonger coating. In order to verify the effectiveness performance of the deep learning in tongue coating evaluating method, we classify the 3 types class(no coating, some coating, intense coating) of an amount of tongue coating by using CNN model. As a results by testing a building the tongue coating sample images for learning and verification of CNN model, proposed method is showed 96.7% with respect to the accuracy of classifying an amount of tongue coating.

This paper presents a fast calculation method for evaluating of voltage stability margin (MW) using the line flow equation in polar form. Here, Line flow equations $(P_{ij},\;Q_{ij}$ are comprised of state variable, $V_i,\;{\Delta}_i,\;V_j$ and ${Delta}_j$, and line parameter, r and x. using the feature of polar coordinate, these becomes one equation with two variables, $V_j,;V_j$. Moreover, if bus j is slack or generator bus, which is specified voltage magnitude in load flow calculation, it becomes one equation with one variable $V_ i $ that is, may be formulated with the second-order equation for $V^2_i$. Therefore, multiple load flow solutions may be obtained with simple computation. The obtained load flow multiple solutions are used for evaluating of voltage stability through sensitivity analysis or its closeness. Also, the method is proposed to calculate for voltage stability margin considering shunt capacitor, which is important element for evaluating of voltage stability. The proposed method was validated to sample systems.

Evaluating service lives of rubber materials at certain temperatures requires a destructive method (typically using elongation at break). In this study, a non-destructive method based on hardness change rate was proposed for evaluating the service life of chloroprene rubber (CR). Compared to the destructive method, this non-destructive method ensures homogeneity of CR specimens and requires a small number of samples. Thermal accelerated degradation test was conducted on the CR specimens at 55, 70, 85, 100, and 125℃, and the tensile strength, elongation at break, and hardness were measured. The results of the experiment were compared to those of the accelerated life evaluation method proposed in this study. Comparing the analyzed lives in the high temperature region (70, 85, 100, and 125℃), the difference between the service lives for the destructive method (using the elongation at break) and non-destructive method (using the hardness) was approximately 0.1 year. Therefore, it was confirmed that the proposed non-destructive evaluation method based on hardness changes can evaluate the actual life of CR under thermally accelerated degradation conditions.

When fitting a response surface model, the least squares estimates of the model's parameters and the prediction variance will generally depend on how the response surface design is blocked. That is, the choice of a blocking arrangement for a response surface design can have a considerable effect on estimating the mean response and on the size of the prediction variance even if the experimental runs are the same. Therefore, care should be exercised in the selection of blocks. In this paper, we prognose a graphical method for evaluating the effect of blocking in a response surface designs using cuboidal regions in the presence of a fixed block effect. This graphical method can be used to investigate how the blocking has influence on the prediction variance throughout the entire experimental region of interest when this region is cuboidal, and compare the block effect in the cases of the orthogonal and non-orthogonalblockdesigns, resfectively.
