  • Due to the downturn in the local construction business, entry into the overseas markets has been regarded as one of the core tasks of the building sector and the government. Thus, entry into overseas markets, not only by large and middle-standing enterprises, but also by small and medium sized enterprises, has recently become a major construction policy. Therefore, this study identified and evaluated overseas construction support policies in the field of construction engineering, ranked them as the policies for developing market development funds, fostering and educating expert workers, and supporting the provision of information on winning orders. Through these policy assessment results, the study proposed improvement measures from the government and from the business side. As for the government viewpoint, a measure of providing information suited to engineers in design companies, project manager (PM), construction manager (CM), a measure of producing skillful workers through the expansion of education support policies, and the promotion of specialized overseas workforce in the construction engineering sector were proposed. In the construction engineering industry, this study suggested measures for securing global expert manpower, sharing performance of overseas construction market development project, strengthening construction project management capacity, and strengthening risk management.

  • Generally, they respond to a phenomenon, with their any way, which they have looked at in their surroundings, and also put into their action successively and variously according as what it is. A person who has not so much problems in experiential education added to mental and physical ability prefers controlling his manner by himself as seeing, listening and feeling to being cured it by other physical support. Meanwhile, even though there are tools that we use conveniently in everyday life, it is sometimes required that user is able to control his action by himself with a certain interactive function to deal with a accidental situation. For example, in the home, when they were cooking, washing dishes and taking a bath they would not often control their minds on how to act about flowing water through the faucet going back and forth between saving and easygoing. By reasons of those statements, the project has been studied to propose the new conceptual faucet which digital technology is applied to, for recognizing the volume of water flowed through water pipe as counting it with built-in flow meter, and then saving water as controling the water-flow with faucet lever. It means that homemakers can observe the flow rate of water from the faucet placed in front of the sink in kitchen and control it right away for saving water. For studying this project, the kinds and features of the various flow-meters that measure the volume of water-flow were researched and analyzed for taking a reasonable type to the new ideal faucet. According to this analyzing, turbine-flow-meter was selected as appropriate form for the digital display-built-in faucet that would be presented in this project. As the next step, the basic structure was created for developing a new conceptual faucet. Finally two models have been presented through several steps for making the suitable shape to the new style faucet.

  • This study was performed to understand the bacteriologic contamination level of radiological equipments which have frequent contacts with patients in the Department of Radiology of an university hospital in Busan area. Before sterilizing in-patient of the radiology rooms, MRSA, VRE, acinetobacter baumannii, candida albicans, and enterococcus sp. were detected. After sterilization, all the bacteria were not found. As examine times become longer, more bacteria were detected and after 7 hours, bacillus sp.(GPR), CNS, acinetobacter baumannii, and Enterococcus sp. were detected. After examining infected patients, bacillus sp.(GPR), VRE, enterococcus sp. CNS, and micrococcus sp. were detected and on the hands of radiological technologists, CNS, enterococcus sp. escherichia coli, and enterobacter sp. were detected. Similar species of bacteria were detected from each radiology room, but pseudomonas aeruginosa was detected on the handles of portable radiological equipments and the chair in the waiting room. Therefore, it is the most important to regularly sterilize radiological equipments and devices which have frequent contacts with patients and to sterilize them right after the use of infected patients in order to prevent the spread of infection. Also, thorough hand washing, education on infection and management for the characteristics of Department of Radiology should be performed for the systematic prevention of infection.

    • In this study, mechanical property on the composite material of aluminum foam core is investigated by simulation analysis. Impact energies such as 50J, 70J, and 100J are applied to the specimen model. The maximum load occurs at 3.4ms for 50J, 3.2ms for 70J, and 3.2ms for 100J respectively. The striker penetrates the upper face sheet, causing the core to be damaged at 50J test but the lower face sheet remains intact with no damage. It results in occurring with the energy of 52 J. At 70J test, it penetrates the upper face sheet and penetrated the core. And the striker causes the lower face sheet with damage. And it results in occurring with the energy of 65 J. Finally at 100J test, the striker penetrated both the upper face sheet and core and even the lower face sheet. The load becomes maximum at the time when striker penetrates through the upper plate and it rapidly reduced. And then the load increases rapidly when reaching the lower face sheet. And it decreases again. It results in occurring with the energy of 95 J.

    • Purpose: This study was conducted to identify the prevalence and related factors of metabolic syndrome in Korean adolescents. Method: Based on data from the Korea National Health and Nutrition Examination Survey of 2015, 404 adolescents aged 12-18 years were enrolled. We used the adolescent Ford method as the diagnostic criteria for adolescent metabolic syndrome. The data were analyzed using descriptive statistics, t-test, $x^2$-test, and logistic regression with SPSS WINDOW 23.0 program. Results: The prevalence of metabolic syndrome in Korean adolescents was 6.5% (6.5% for boys and 6.4% for girls). Among metabolic syndrome components, the prevalence of elevated blood pressure (28.8%) was the highest, followed by elevated triglycerides (21.3%), increased waist circumference (14.1%), decreased high density lipoprotein-cholesterol (11.5%), and elevated fasting blood sugar (7.8%). The only factor associated with metabolic syndrome in both boys and girls was the Body Mass Index (BMI), and the likelihood of a metabolic syndrome increased by 1.6 to 2.3 times (Adjusted OR=1.552 to 2.313, p=0.001) as the BMI increased. Conclusion: Based on the results of this study, an intervention program should be developed and provided to maintain the BMI in the normal range for the prevention and management of metabolic syndrome in Korean adolescents.

    • The CPR guidelines emphasize the delivery of effective chest compressions but do not address the effects of chest compressions on CPR providers. This study determined the effects of chest compressions on healthy adult firefighters' symptoms, hemodynamics, and electrocardiography after performing multiple cycles of CPR. Healthy adult firefighters were trained in CPR and performed CPR on mannequins. The provider vital signs, electrocardiography, and fatigue scores were determined immediately before CPR, after 5cycles of CPR, and after 10 cycles of CPR. In addition, the presence of clinical symptoms among the providers was determined after CPR; 39 firefighters participated in the study. Their mean age was $35.54{\pm}10.26years$. Many providers developed fatigue, shortness of breath, and dizziness. Significant changes in heart rate (p=0.000), respiratory rate (p=0.010), end-tidal CO2(p=0.000), O2 saturation(p=0.000), and pulse pressure (p=0.000) were observed after both 5 and 10 cycles of CPR. One participant developed sinus dysrhythmia and premature ventricular contractions after 10 cycles of CPR. The delivery of chest compression results in fatigue and hemodynamic alterations in many young healthy adults after performing 5 or 10 cycles of CPR. The CPR guidelines and education should take into consideration the effects of chest compressions on CPR providers.

    • Hyperbranched liquid crystalline polymers with azomesogenic and cholesteryl groups in their terminal positions were designed and synthesized by direct polycondensation reaction. The chemical structures and thermal and mesomorphic properties of the synthesized polymers were investigated by FT-IR, $^1H-NMR$, differential scanning calorimetry (DSC), thermogravimetry analysis (TGA), and polarizing optical microscopy (POM). The inherent viscosities (${\eta}_{inh}$) of the polymers were measured to be between 0.30 and 0.50 dL/g in phenol/p-chlorophenol/1,1,2,2-tetrachloroethane (25/40/35 = w/w/w). The degree of branching (DB) in these polymers ranged from 0.37 to 0.75; they, as amorphous polymer, showed glass transition temperatures ranging from 80 to $120^{\circ}C$; the polymers readily dissolved in most of the organic solvents used in the experiments. Only hyperbranched polymers with a cholesteryl group as their mesogenic group showed liquid crystalline phases.
