Micro On-Off valves are currently recognized as the core technology in the fields of the micro fluid chip fur medical applications and production lines of semi-conduct chip. Micro valves that operate by compressed air need the high-speed responsibility, repeatability, the absorbability and the uniform pressure by the poppet. In this study, Micro On-Off valves that posses the high-speed responsibility and the high rate of flow have designed and analyzed through the law of equivalent magnetic circuit and Finite Element Method (FEM) respectively. In case of poppet, Flow field characteristic was analyzed by the variation of poppet and it was able to display flow field by changing the location of the poppet. Also, we verified possibility of the design through the static and dynamic pressure and the 3D distribution curve of the force by working the front poppet.

In this work, a model of a functionally graded (FG) nanotube conveying fluid embedded in an elastic medium is developed based on the nonlocal strain gradient theory (NSGT) in conjunction with Euler-Bernoulli beam theory (EBT). The main objective of this research is to investigate the nonlinear vibration and stability analysis of fluid-conveying nanotubes. The governing equations of motion are derived by means of Hamiltonian principle. The analytical expressions of nonlinear frequencies and critical flow velocities for two different types of boundary conditions including pinned-pinned (P-P) and clamped-clamped (C-C) conditions are obtained by employing Galerkin method as well as Hamiltonian Approach (HA). Comparison of the obtained results with the published works show the acceptable accuracy of the current solutions. The effects of the power-law index, the nonlocal and material length scale parameters and the elastic medium on the stability and nonlinear responses of FG nanotubes are thoroughly investigated and discussed.

In Korea, where the world's first cloud computing development law was created, cloud service technology has been developing so far, and the industries to which artificial intelligence and big data technologies can be applied based on this are increasing. It is important for domestic and overseas cloud operators to secure many partners in order to provide optimal services to users. It is also important to systematically develop the partner's technology and discover new partners. In particular, the public, medical, and financial sectors are industrial fields that are difficult for domestic as well as global cloud service providers to expand without the help of partners. This study analyzes partner policies for industries caused by domestic regulations through domestic and foreign cases, and aims to establish partner management policies optimized for the domestic environment.

In the present study, thermoelsatoplastic stresses and displacement for rotating hollow disks made of functionally graded materials (FGMs) has been investigated. The linear elastic-fully plastic condition is considered. The material properties except Poisson's ratio are assumed to vary in the radial direction as a power-law function. The heat conduction equation for the one-dimensional problem in cylindrical coordinates is used to obtain temperature distribution in the disk. The plastic model is based on the Tresca yield criterion and its associated flow rules under the assumption of perfectly plastic material behavior. Exact solutions of field equations for elastic and plastic deformations are obtained. It is shown that the elastoplastic response of the functionally graded (FG) disk is affected notably by the radial variation of material properties. It is also shown that, depending on material properties and disk dimensions, different modes of plastic deformation may occur.

Objectives: We investigated the current status of the consent form for bee-venom pharmacopuncture therapy, which is using in Korean medicine hospitals. We suggest the development of a standard informed consent form. Method: Through the questionnaire survey, status of using informed consent form was identified at 24 Korean medicine hospitals. We analyze different types of informed consent form, which was developed by each hospitals. We investigated the types of informed consent forms for various medical procedures through electronic searches. A standard informed consent form for bee-venom pharmacopuncture therapy was developed based on the medical law and the standard informed consent form for medical procedures developed by Korea Fair Trade Mediation Agency. Result: In our survey, 65% of the hospitals do not use consent well, only 35% of the hospitals use informed consent form, and the most hospitals use self-developed informed consent form. As a result of analyzing the contents of informed consent form used in each hospitals, the explanation of diagnosis, treatment precautions, suggestions for other treatments, consequences of not performing the scheduled procedure, possibility of treatment change was insufficient. 48% of hospitals manage consent in recording on a chart, 39% in scanned documents, and 13% in digital electronic consent form. Conclusion: A standard informed consent form for Bee-venom pharmacopuncture therapy include diagnosis, effectivness, necessity, indications, method, skin reaction test, hypersensitivity questionnaire, treatment precautions, possible hypersensitivity reactions and countermeasures, suggestions for other treatments, consequences of not performing the scheduled procedure, possibility of treatment change and the name of doctor.

Today, the basic problem of functional safe management of Korean Disaster Control system was separately administrated 33 acts that are relating to safe management in 13 ministries. Because of the facts that the fire service is not provided practically, the control system and risk management for safe administration are not operated, the information can not be shared with each other, and the various laws have the lacks of linkage, the National Safe System was appeared unsteady. The roles and functions of fire service have started with restriction to operate structurally and institutionally, which operational structure of fire service is becoming weak. As a result, the federal and local fire organizations have not reached yet to the institutionalization and the local fire service agencies have bias with the task regarding the fire service because of the relation between organizational structure and the local fire agency. With the enforcement of the federal and local fire system, professionality and autonomy for making policy, and dealing with changes of fire service positively, the national fire service on the policy performance can be established. Promotion of research and development and education training to strengthen innovation in technology and competition in fire industry will contribute to the firmly establishment of control system to prevent from fire, flood, terror and national disaster. This article proposed that (a) the established law and administration, agency are required efforts to effectively operate fire service system; (b) the national fire service agency, national college of fire, national institute of science fire, and national fire service hospital should be early established to make firmly policy to operate effectively and practically. These kinds of innovational acts are known the best ways of operating solid policy of national fire service system.

Background: Colorectal cancer is the second most frequent cancer in Malaysia. Nevertheless, there is little information on treatment and outcomes nationally. We aimed to determine the demographic, clinical and treatment characteristics of colorectal cancer patients treated at the University Malaya Medical Centre (UMMC) as part of a larger project on survival and quality of life outcomes. Materials and Methods: Medical records of 1,212 patients undergoing treatment in UMMC between January 2001 and December 2010 were reviewed. A retrospective-prospective cohort study design was used. Research tools included the National Cancer Patient Registration form. Statistical analysis included means, standard deviations (SD), proportions, chi square, t-test/ANOVA. P-value significance was set at 0.05. Results: The male: female ratio was 1.2:1. The mean age was 62.1 (SD12.4) years. Patients were predominantly Chinese (67%), then Malays (18%), Indians (13%) and others (2%). Malays were younger than Chinese and Indians (mean age 57 versus 62 versus 62 years, p<0.001). More females (56%) had colon cancers compared to males (44%) (p=0.022). Malays (57%) had more rectal cancer compared to Chinese (45%) and Indians (49%) (p=0.004). Dukes' stage data weres available in 67%, with Dukes' C and D accounting for 64%. Stage was not affected by age, gender, ethnicity or tumor site. Treatment modalities included surgery alone (40%), surgery and chemo/radiotherapy 32%, chemo and radiotherapy (8%) and others (20%). Conclusions: Significant ethnic differences in age and site distribution, if verified in population-based settings, would support implementation of preventive measures targeting those with the greatest need, at the right age.

Taiwan has experienced rapid economic growth during the past two decades. As a result, the demand for health care in Taiwan has increased rapidly. To meet the rising demand, Taiwan implemented a National Health Insurance (NHI) program on March 1, 1995. This program now covers more than 96 percent of Taiwan's citizens. Implementation of the NHI in 1995 represents fulfillment of a primary social and health policy goals of Taiwan. The goals of the NHI program is to eliminate financial barriers of health care for the citizens, to improve the quality of care. To achieve these goals, the NHI was designed on the following principles: 1. All Taiwan citizens are compul내교 joined the NHI program by law; 2. The NHI program provides comprehensive services; 3. The NHI is run by one single govt' subsidy; 5. The NHI adopt fee-for-services scheme to pay medical expenses and copayment to avoid abouse of medical services. However, the scheme did not bring in the efficient use of health care C. National Health Council, 1986 NARC, Aging in Japan, International Publication Series 1991;2 Kahana EF. Kiyak HA.
