For the purpose of finding out the acoustical characteristics of exterior materials in bridge, analytical studies are performed with boundary elements method by using the commercial program SYSNOISE. Before analysis, to figure out material property, it was conducted experiments of absorption coefficient for absorptive material. And prediction of pressure were conducted I GIRDER type (before & after installation of absorption panel ) and BOX GIRDER type (before & after installation of absorption panel) The results show that when the absorption panel is installed, environment around bridge can help reduce traffic noise. It was proved to be the effective noise reduction counter-plan for a traffic noise in the bridges.

The objective of this study is to provide improved methodology based on the IPA method. One case studies are solved by the proposed method. this study present the method that give value to use SN(Signal-to-Noise) ratio in IPA. A case study of lecture satisfaction are solved by the proposed method and the existing method. Also, the result is compared with the existing method using Mean and the proposed method using SN ratio.

The importance of Human Resource Management is big issue in business management recently. However, employ's job satisfaction is appeared as low. In this study, surveys were conducted among those long-term employs. The importance of job satisfaction is prioritized by AHP analysis based on results of survey to compare to the results of previously studied research. And this study will contribute to improvement of job satisfaction by comparing the facts in two different groups of occupation.

Plant management have a greatest influence on the corporate variety of tasks such as production, quality, environment. So, various performance indices for plant management are operating. But plant management tasks can be carried out effectively, so that all of how to organize and efficiently manage indicators is lacking real condition In this paper, improved profitability, cost savings by applying the concept for the performance assessment, plant management services, such as the key indices for performance according to the objectives of the firm. Dashboard for plant management work using me to develop a system that manage.

The purpose of this study is to monitor the current adverse reactions in administering CT contrast agents at general hospitals and also to suggest the practical guidelines to minimize the risk and to show the successful patient management. At four Dajeon city general hospitals, the contrast agents were administered in 646,828 cases and the overall prevalence of adverse reactions was 4,110 cases from January 2010 to December 2013. However, we excluded the two hospitals’ 3,658 cases because the patients’ data was inadequate. Consequently, the case surveys on the rest of 452 cases have been studied and submitted. After comparing the patients with a control group, we evaluated that the key factors of the adverse reactions were the gender and age difference of the patients, the examination period, the examination method, the quantity and administrating speed of the contrast agents. Even though the four general hospitals have their own management systems on adverse reactions, but their systems were not satisfying. To improve the quality of the management systems and to investigate further cases, some hospital administration procedures on the subject should be systemized and general hospitals should follow the recommended procedures. Moreover, the existing three-year-term evaluation should not only judge the adverse reaction management but also conclude some details on the sub criteria of the evaluation. The details on the sub criteria include the contrast agent characters, the quantity and administrating speed of the drug, the incidents’ occurred time, an anamnesis; a case history, the medical history of the patients and the reaction occurring body parts, and the examination title. The details of the medical examiners are also added to the sub criteria.

Beam quality is changed about magnetic field of bending magnet. Evaluation of beam quality using PDD(Percentage Depth Dose) at 10cm depth at recommendation of AAPM(America Academy of Pain Medicine). However this evaluation shows fragmentary element. Therefore this study is applied to three value, 10cm divided by 5cm depth PDD, 20cm divided by 10cm depth PDD, 30cm divided by 20cm depth PDD, at change the magnetic field. PDD is measured at magnetic field changed ±1%, ±2% at 6MV(Mega Voltage), 10MV photon. The plan technique is 3 portal plan using Core-Plan at human pelvic phantom. Conventional and presented methods are compared at maximum and minimum dose. The presented method increased discernment of relieve the unequal distribution and energy area than conventional method. Henceforth, application of presented method will be considered. Development of energy measurement method and detector miniaturization will be needed about continuous study.

As people seek a healthy, wealthy, and quality life more than before, interests in mineral water are picking up and the consumption continues to increase accordingly. In an experiment to examine changes in the water quality after mineral water on the market was kept indoor and outdoor for four weeks, there seemed to be no problem in external appearance. Water kept in an outdoor storage contained more odor-savor than water kept in an indoor storage. Odor was not detected in 90% of the sample, and savor not in 80% of it. As for the mechanism of odor-savor generation, the elution of chemical substances from a container may be taken into consideration. In general, odor and savor have turned out to be in close correlation to each other. The average number of bacteria in the sample mineral water was 200±10 CFU/mL, and such factors as area of storage and ozone post-treatment did not cause significant effects on the reproduction of common microbes. Hence, it is thought that strict regulations on a production process and reduction of the period of circulation will contribute to customers consumption rates.

To solve the serious problem of insufficient manpower in medium and small scaled companies, our country allows introduction of foreign manpower for 5 business types such as manufacture industry, service industry, etc. and there are 226,825 people who entered by employment license system(E-9) in Sep. 2013. However, according to the results of investigation 「actual status and difficulties of foreign manpower's employment of medium and small scaled manufacturing companies」of KFTA in 2013, 36.4% of respondents responded that current scale of introducing foreign manpower is insufficient to solve difficulties of insufficient manpower in industrial world and 37.7% of them responded that the quarter of new employment is insufficient. So, they hope that current quarter system of foreign manpower can be abolished. Meanwhile, introduction scale of foreign manpower was decided by 53,000 people so as to solve enterprise difficulties in manpower and vitalize economics this year, but illegal aliens are 39,623, more than 17.5%, in Sep. 2013 after employment expiration. Therefore, it becomes serious social problem. Government displays various support businesses so that foreign workers after employment expiration can return to their homeland legally. This thesis intends to find measures to maintain royalty for our country and support their smooth resettlement through the analysis on homecoming support business of foreign workers.
