  • Construction equipment noise has caused much annoyance for a number of dwellers in nearby construction field and it has become a very serious issue in our living environment. Therefore, in our country, a practical solution and a better method of reducing construction equipment noise are highly required in construction field. Practical solutions for the construction equipment noise, however, are very difficult to obtain, because of the lack of basic data and insufficient research works. Especially, in order to establish a successful sound isolation plan for piling work noise, which has high sound pressure level, the characteristics of the impact noise should be closely monitored and analyzed. This study attempts to survey the characteristics of attenuation and propagation of construction equipment noise in piling work by SIP(soilcement injected precast pile) method. In addition, this study intends to get the basic data to establish a standard about construction noise.

  • For practical education, many practices using various practical equipments have to be provided to students. In this study, the application of learning curve to represent student's learning process in a practical education using a equipment was studied. Learning curve model was originally developed in production management and based on human performance in human factors aspects. In this study, the application of learning curve model was studied on the eye tracking system, which is used to evaluate the usability of a product in design area. As a case study for its applicability, practical education for eye tracking system was provided to three students and then task completion times were measured for hardware system setup and gaze image recording. Learning curves were estimated for two tasks and then task completion times were predicted using the learning curves. Through ANOVA(analysis of variance) and correlation analysis, the applicability of learning curve to practical education was analysed. As the result, learning curve could be effectively applied to practical eduacation using equipment.

  • Lately, a guideline for seismic design of electric substation facilities has been newly prepared and issued. The guideline adopts a new simplified dynamic analysis technique called "pseudo-resonance method" from the design code of Japan. The method can effectively consider resonance effect of structural system during earthquake motion. However, reliability and practical applicability of the method have not been fully guaranteed under the different seismic and engineering situations in Korea. This paper presents a validation study of the pseudo-resonance method for practical seismic analysis. For this purpose, various parametric studies have been performed using recorded earthquake motions and idealized substation equipment models. The results showed that the pseudo-resonance method can be effectively used for the practical seismic design of substation facilities in Korea.

  • In this paper, we examined trends and regulations of the global medical equipment industry through literature search. The medical equipment industry is attracting attention as a new growth engine in the Fourth Industrial revolution. However, the medical device industry is a highly competitive field due to product diversity, short product life cycle and technological advances. In addition, Medical equipment are related to human health and safety. Therefore, it can only be exported if it is approved by national or international standards. Therefore, from the development stage of the product, the medical equipment should designate the country to be exported and develop a medical equipment that meets the requirements for licensing the medical equipment in the country. Therefore, In this paper, In this paper, we will present the practical considerations of the medical equipment exporting company by examining the global medical equipment market trends and the regulations related to medical equipment in major countries.

  • The reliability evaluation of the electrical distribution networks (EDN) requires sufficient consideration of the effects of planned outages. The planned outages of the EDN can be divided, by outage models and their effects on the reliability into two major categories: by equipment and by feeder. After studying the characteristics of different categories of planned outages, this paper expands the classification of load points by outage time from 4 types to 7 types and defines corresponding reliability parameters for the different types. By using the section algorithm, this paper proposes a reliability evaluation technique of EDN considering equipment random failures and two categories of planned outages. The proposed technique has been applied to the RBTS-BUS6 test system and some practical EDNs in China. The study results demonstrate that the proposed technique is of higher practical value and can be used for evaluating the reliability performance of EDN more efficiently considering the planned outages.

  • This study analyzed the effects of smart phone using for business on work performance in the field. We classified functional and practical aspects of smart phone affecting employee's work performance through former studies. As independent variables, we selected portability of equipment, rapidity of information and ease of use for functional side, and selected fit to work and subjective norms for practical side. And dependent variable was work performance. We also suggested that innovation resistance would be a moderator. The results showed that the effect of work performance was influenced by portability of equipment and fit to work. However, hypotheses on moderating effects of innovation resistance were not supported. This study made a discrimination in terms of an application phase of smart phone as against former studies. The results of this study will provide practical implications for related enterprises in the field to develop ways of using smart phone as an effective strategy.
