게임분석 방법에 대한 다양한 연구들이 진행되었다. 본 논문에서는 게임의 필수적인 행동의 Core, 게임 문제를 해결하는 행동의 Primary, Core와 Primary를 도와주는 행동의 Secondary로 분류하는 분석 방법을 제안한다. 제안 방법은 게임의 장르적 유사성 및 특징, 콘텐츠의 풍부함, 숙련 난이도를 분석할 수 있다. 사례분석과 사례 조사를 진행하여 분석 사항이 객관적 게임 경험과 일치하는지 확인하였다. 본 연구의 결과는 게임 기획 단계에서 유사 게임과 비교하면서 개발을 진행해나가는데 응용될 수 있을 것이며, 이러한 과정을 통해 게임 기획력 향상 및 경쟁력 있는 게임 개발에 도움될 수 있을 것이라 기대한다.

At the choice of aviation company, safety appears as biggest variable than expenses, speed and comfort so these are concerned not only aviation companies but also countries and customers. Until now, ICAO has been making effort to reduce the flight accident through the safety advice of aviation part, establishment of standard, education, training and develop of navigation aids. Especially in 2008, they emphasize that the flight accident is reduced through researches and applications about SMS as safety regulation. Important primary factor to give influence about promotion of SMS is practice of organization and for this, to investigate recognition about safety management and culture of members. At point of this, this research analyze the recognition degree about how to manage safety and SMS for pilots an mechanics of Korea.

근대 지리학 방법론 논쟁에서 가장 주요한 쟁점은 지역 지리학의 학문적 성격에 대한 논란이었다. 그러나 대부분의 논의는 지역 연구의 절차를 제시하기보다는 지역 지리학을 형이상학적으로 정당화하는 데 머물렀다. 본 연구에서는 이러한 견해를 비판적으로 검토하기 위하여 지역 지리학 방법론에 내재하는 전제들 가운데에서도 부분과 전체의 관계에 대한 존재론적 가정을 가장 중요한 준거로서 설정하였다. 대부분의 논의는 유기체론에 근거하여 지역을 복합적 존재로서 인식하고, 생명체와의 비유를 통해 지역의 속성을 파악해야 한다고 주장하였다. 그러나, 단위 지역이라는 전제의 한계와 더불어 단순히 요소들을 열거하는 데에 머물렀으며, 지역의 복합성을 포착하지 못하였다. 이러한 한계는 생활양식이라는 전제 위에서 출발한 데에서 오는 당연한 귀결이었다.

From recent research, it has revealed that Electroacitve polymer(EAP) has a physical limitation. Carbon nanotube(CNT) is known as the promising material which has excellent electro-mechanical characteristics and is mostly defect-free. It is expected that a successful synthesis of CNT and Nafion known as a primary material for IPMC would make a great improvement on its electro-mechanic feature. In this paper, we suggest the method of synthesis of CNT with Nafion which improves electro-mechanical characteristic. Using mechanical dispersion with Nafion and Isopropyl Alcohol(IPA), we disperse Single-walled carbon nanotubes(SWCNT). For a uniformly layer of CNT, we used a spray gun on a hot plate by a simplified method. In the result, we fabricated a disperse SWCNT/Nafion composite uniformly.

Thick film mechanical sensors can be categorized into four main areas piezoresistive, piezoelectric, piezocapastive and mechanic tube. In this areas, the thick film strain gage is the earliest example of a primary sensing element based on the substrates. The latest thick film sensor is used various pastes that have been specifically developed for pressure sensor application. The screen printing technique has been used to fabricate the pressure sensors on alumina substrate($Al_2O_3$). Thick film capacitive of strain sensing characteristics are reported and dielectric paste based on (Ti+Ba) materials. The electric property of dielectric paste has been studied and exhibit good properly with good gage factor comparable to piezoresistive strain gage. New piezocapacitive strain sensor was designed and tested. The output of capacitive value was good characteristics.

Thick film mechanical sensors can be categorized into four main areas piezoresistive, piezoelectric, capacitive and mechanic tube. In this areas, the thick film strain gage is the earliest example of a primary sensing element based on the substrates. The latest thick film sensor is used various pastes that have been specifically developed for pressure sensor application. Some elastic materials exhibit a change in bulk resistivity when they are subjected to displacement by an applied pressure. This property is referred to as piezoresistivity and is a major factor influencing the sensitivity of a piezoresistive strain gage. The effect of thick film resistors was first noticed in the early 1970, as described by Holmes in his paper in 1973.

Many researchers are recently studying about Electroactive polymer(EAP). But it has a physical limitation, because of property of material. Carbon nanotube(CNT) is known as the promising material which has excellent electro-mechanical characteristics and is mostly defect-free. It is expected that a successful synthesis of CNT and Nafion known as a primary material for IPMC would make a great improvement on its electro-mechanic feature. This study focuses on the method of synthesis of CNT with Nafion which improves electro-mechanical characteristic. To come up with mechanical dispersion with Nafion and Isopropyl Alcohol(IPA), we dispersed Single-walled carbon nanotubes(SWCNTs). For a uniformly layer of CNT, we used a spray gun on a hot plate by a simplified method. We fabricated a disperse SWCNT/Nafion composite uniformly. Through the use of the E-beam evaporator to form an uniform electrode layer, we consummated the IPMC actuator. This result shows improving 1.5 times mechanical properties about driving force in IPMC.

Failure mode and effects analysis (FMEA) is a preventive technique in reliability management field. The successful implementation of FMEA technique can avoid or reduce the probability of system failure and achieve good product quality. The FMEA technique had applied in vest scopes which include aerospace, automatic, electronic, mechanic and service industry. The marking process is one of the back ends testing process that is the final process in semiconductor process. The marking process failure can cause bad final product quality and return although is not a primary process. So, how to improve the quality of marking process is one of important production job for semiconductor testing factory. This research firstly implements FMEA technique in laser marking process improvement on semiconductor testing factory and finds out which subsystem has priority failure risk. Secondly, a CCD position solution for priority failure risk subsystem is provided and evaluated. According analysis result, FMEA and CCD position implementation solution for laser marking process improvement can increase yield rate and reduce production cost. Implementation method of this research can provide semiconductor testing factory for reference in laser marking process improvement.
