In preliminary ship design, a parametric study is a more realistic way to explore design space and analyze design problem than an optimization technique due to time-consuming computational work or a difficulty in incorporating all constraints into the optimization formulation. In the parametric study, feasible alternatives are examined in various aspects; the best one can be selected. Among the aspects, the strength assessment by FE analysis is an essential process in the ship design. This paper proposes a system to facilitate a parametric study for FE model based on design of experiment (DOE). It works on a FE pre-processor environment and assists a user to define a parametric study by interacting with FE model. It also provides an interface module with a FE solver in order to control the input file and extract predefined FE results from the output file. Based on the proposed system, a better understating and a better design are expected to be achieved.

Method: We reviewed the papers of communication analysis studies in various fields and summarized communication error researches. Results: We proposed perspectives for communication error analysis and explained the need for extended analysis framework using advanced human-machine interfaces, which will cause the change of communication between operation team, including shifted abstraction phenomena. And we describe main concepts and the case study of H-H-S framework and finally introduce current studies of communication analysis in nuclear domain. Conclusion: The goal of communication analysis is common in all industries. We have to share and co-work for event prevention. Application: The results of the communication analysis might help to facilitate the understanding for interested researchers.

This paper describes the design and evaluation of a noise suppressing hydrophone that is robust to external noise without sacrificing its performance as a receiver. To increase robustness of the receiver to the external noise, first, effects of location of external noise on its performance are analyzed with the finite element method (FEM). Based on the results, geometrical variations are implemented on the structure with additional air pockets and damping layers that work as acoustic shields or scatterers of the noise, and fourteen trial models are developed for the noise suppressing hydrophone structures. The results show that the effect of the external noise is most significant when it is applied to near the mid-side surface of the hydrophone housing. The external noise is isolated most efficiently when two thin damping layers combined with five air pockets are inserted to the circumference of the hydrophone housing. Overall, of the fourteen structural variations of the hydrophone, the best one shows about 87% reduction in the response of the original structure to external noise.

A Study on the strategic methods for internal marketing of Family Restaurant. We know that customer satisfaction in measuring the effect of marketing performance on employees in service industry. There are four strategies of internal marketing for service-employee, which are participation-promotion and manner-management of employee, classification to employee, communication strategy, motivation environment for employee. First, communication, sales and service technology of employee can be developed and improved through the education and training. Second, company can make better achievement by classifying life-style and individual desire. Third, communication strategy can improve service quality by development of team-work through the confidence and joint-responsibility. Fourth. the company make environment which employee can compete by offering incentive fairly and properly. In the conclusion, when employees serve customers in a depressed attitude, they neglect service process and bring about customer non-satisfaction. This have negative effect on external customer satisfaction in the short term. And so that customer-satisfaction can't exist without employee-satisfaction. that is job-satisfaction is the goal of company. therefore study about internal marketing action should be go on.

In this work, an exponentially tapered microstrip antenna was implemented using a resistive loading technique in order to suppress the internal reflections. The inductive loading was realized by introducing slits on the antenna to improve radiation efficiency. Compared with a resistive-loaded antenna, the proposed antenna had an average improvement of about 6.2% in radiation efficiency within the range of 2-10.5 GHz. In addition, the highest peak of the radiated short pulse from the proposed antenna became 45% greater than that of an antenna with resistive loading only.

IT 기술의 발전과 네트워크 보급에 힘입어 인간의 의사소통 방법도 나날이 발전되어가고 있다. 대면(Face to Face) 커뮤니케이션은 지금까지 가장 효과적인 방법이 되어왔지만, 이제는 통신 기술의 발달과 더불어 여러 형태의 유용한 소통방법들이 보급되었고, 생활화되기 시작했다 특히 PC의 대중화와 초고속 통신망의 보급, 그리고 휴대전화의 보편화는 의사소통 방법의 다양화에 큰 영향을 주었다. 보이스 메일은 텍스트 기반 소통과는 다른 음성으로 의사 전달을 하는 소통 방식이면서도, 대표적 텍스트 기반의 시스템인 이메일처럼 비동기적인 통신 수단이기도 하다. 본 논문은 기존 커뮤니케이션 미디어는 물론 보이스 메일을 사용하여 실제 프로젝트를 수행한 케이스를 관찰, 분석하고, 이것을 기반으로 프로젝트 수행 시 다양한 의사소통 방법에 대한 이해 및 보이스 메일의 사용상의 특성에 대해 살펴보고자 한다.

This study reports the preparation and characterization of nanohydrogels by using sodium alginate as a model material. Alginate nanohydrogels (ANH) were prepared by emulsification-diffusion method in a w/o system with 1,2-diacyl-sn-glycero- 3-phosphocholin as the lipophilic surfactant. The effects of the alginate to surfactant ratio and the remaining water contents on the mean particle size and swellability of ANHs were investigated in terms of the concentration, agitation speed, and agitation time. The feasibility of using nanohydrogels and their controllability were proved by the water the absorbency of ANHs during a 7-day evaluation by dynamic light scattering. In this work, the mean particle sizes of ANHs could be controlled from 49.2 nm (measured in ethanol phase) to $1.9{\mu}m$ (measured in water phase, after 7 days of water absorption).
