본 논문은 게임성 평가 모델 설계를 기반으로 온라인 게임성 평가 시스템 설계 및 구현을 중점적으로 연구하였다. 온라인 게임성 평가 시스템이란 평가 요소를 정의한 모델 설계를 통하여 온라인상에서 게임을 실시간으로 평가하는 시스템을 의미한다. 게임성 평가 시스템은 사용성 평가(Heuristic Evaluation) 기법을 활용하여 기술적 요소, 관리적 요소, 사회적 요소, 경쟁력 요소의 4부분으로 평가를 실시하였다. 게임성 평가의 객관성과 타당성 검증을 위하여 초급자, 중급자, 전문가 세 분류를 통하여 평가를 실시하여 신뢰도를 높였으며, 게임성 평가 포럼을 개최하여 다양한 계층의 의견을 수렴하였다.

In this study, a fluidized bed particle generator was developed to generate an aerosol without supply of compressed air and to increase portability. It was assumed that the mixing ratio of the test particles and beads, the input amount, and the air flow rate supplied to the generator would have effect on the aerosol generation characteristics. The product of these three parameters was set as a characteristic parameter and particle generation characteristics according to the change of the characteristic parameter were observed. As a result, it was confirmed that the input amount of test particles and beads was not suitable as a characteristic parameter and a characteristic parameter expressed as a product of the mass mixing ratio and the air flowrate was newly defined. When the new characteristic parameter is applied, it can be confirmed that the total amount of particles generated from the particle generator is a function of the characteristic parameter. As a result of measuring the amount of particle generation by adjusting the characteristic parameter, it was confirmed that the performance required for the test particle generator for the field inspection equipment of PM-2.5 sensors could be satisfied.

The purpose of this study is to analyze the level of career development competency recognized by the specialists who major in food service currently. To achieve the purpose of this study, the five two-year-courses technical colleges in Kyeonggi-do, Daejeon, Daegu Metropolitan City which include food service department were selected. And total 280 samples of enrolled students were extracted and the 256 students were treated statistically besides the 24 students who responded dishonestly. The analysis results are as follows. First, the male students showed partially higher career development competencies than female students. Second, the second grade students showed partially higher career development competency than the first grade students. Third, the specialists whose family income is over 5 million won showed the highest career development competency, and the students in 3-5 million won and less than 3 million won followed them in order. Fourth, there were differences in competencies of lifelong learning, networking, collecting and utilizing the job information, and self-understanding, and career transition, and the specialists with more qualifications showed higher competency than those who with less qualifications. Therefore, it is necessary to develop a various career education program to enhance career development competencies of food service specialist by individual characteristic.

In this study treats 'Rural Village Development Project'. The ministry of Agriculture and Forestry and Korea Agricultural & Rural Infrastructure Corporation are enforcing this from 2004. A purpose of 'Rural Village Development Project' is as follows. Repairs a function of production farms-residing rest tourism generally after connecting a neighborhood village having the same nature in a small scale unit. Too local human resources and material resources is utilized, and develops various types with specialization. As a result, it is to improve with the quality of life of a farmer. This study finds problems to have broken out in Rural Village Development Project. Therefore, recognize whether it is on to be devoted to rural village and rural community inhabitants to solve the problem how. And analyze a policy characteristic of Rural Village Development Project and basic course. Therefore, provide with materials when decides on plan course of Rural Village Development Project through this. As a result, it is a purpose to give help to Rural Village Development Project. The results of study are follows; First, A state inhabitants, professional group, administration understand an agricultural village, and to be able to learn must be prepared first. Second, the enough time that can carry out study is necessary. Third, must present the guidebook which expresses a local characteristic well. Fourth, it is specialist database construction and network formation.

New product development has been a key element fur organizational evolution. The bulk of research about new product strategy has focused solely on new product development function itself. This paper investigates cross-functional elements in new product development. More specifically, we suggest that there must exist a fit between new product strategy and value chain strategy. It means that, in order to support new product development activity, there must exist a relevant value chain strategy. We consider three types of integration - internal integration, customer integration, and supplier integration - as strategic elements of value chain strategy. For the case of new product strategy, we consider market newness and product technology unfamiliarity as strategic elements. We also consider two types of learning characteristic, i.e., \\\"fast-adaptive learning\\\" and \\\"slow-adaptive leaning\\\" as control factor. Learning characteristic represents firms organizational capability related with organizational learning. For example, fur fast-adaptive learning case, the effect of integration appears early in time. System dynamics simulation is employed to verify our research framework. The results exhibit that there must exist cross-functional relationships between value chain strategy and new product strategy in order to shorten total development time.al development time.

M125 booster is one of the reliable S&A device(safety and arming device) to determine the arming distance of fuze for gun ammunitions from 90 mm to 8 inch in diameter. And it is also well known that the arming distance of M125 booster is determined by the multiplication value of the gun tube property(traveled distance per turn of projectile) and the S&A device property(number of turns to arm), not by the projectile muzzle velocity. We have tried and succeeded in executing a proper analysis on M125 booster to figure out its characteristic constant of arming distance by considering only the gun tube properties and the S&A device properties. More detailed arming distance will be analyzed in the future by considering dynamic characteristics on all elements in the S&A device with vector analysis.

The requirement of acoustic performance about underwater acoustic material which is used in underwater environment more increases. Underwater acoustic material was made by viscoelastic material such as a rubber and a polyurethane etc. In order to increase an acoustic performance, several kinds of inclusions were added to viscoelastic material. In this paper, acoustic modelling and analysis techniques were introduced and the acoustic characteristics of underwater acoustic material were studied. Echo reduction and transmission loss were calculated with volume fraction of inclusion in the material. Also the characteristic impedance and the input impedance of underwater acoustic material were obtained and effects on the echo reduction and transmission loss of material were discussed.

The Quality Function Deployment(QFD) is a Quality Management technique to maximize customers' satisfaction by reflecting customer requirements into all business processes, including concept definition, product planning, parts planning, process planning, production planning, and sales planning. The basic concept of the QFD is to translate customers' requirements appropriately into engineering characteristics, into parts characteristics, into process characteristics, and into specific requirements and activities in production. In this study, we reviewed and analyzed the application process of the QFD to the development of A2 FATC (Full Automatic Temperature Controller), an automotive component developed and produced by company A. It has been reported that by applying the QFD to the development of A2 FATC, company A. achieved 34% improvement in control robustness quality characteristic, 27% improvement in deviation quality characteristic, and 30% improvement in overall quality characteristics.
