  • 최근 정보, 전자, 광, 반도체 등 각종 첨단산업에서는 다양한 형태와 재료의 가공방법이 요구되고 있으며 요구되는 부품의 정밀도도 마이크로 단위에서 서브 마이크로 단위까지의 고도의 정밀도를 요하는 기술들이 점차 늘어가고 있다. 또 더욱 더 소형화 되어가고 있는 마이크로 부품은 기존의 2차원 및 준 3차원에서 완전한 3차원 형태의 기술로 발달하고 있으며 현재 연구가 활발히 진행되고 있는 MEMS 분야에서 구동부 부품이라든가 또는 그를 지지하는 구조체로 쓰일 수 있어 그 활용 가치는 응용에 따라 폭이 넓다고 할 수 있다.

  • This study was performed to investigate the influence of Corporate Social Responsibility (CSR) activity on corporate image and repurchase intention (pre and post measure) after the news of food incident. A questionnaire survey was carried out for 235 college students in Seoul, Korea. The participants were given an instruction with CSR activity of company in food industry and completed the survey. We collected the survey and did the statistical analysis by SPSS. The result of this study was as follows: Significant differences (p < 0.05) were found between the two groups, one was aware of corporation's CSR activity and the other was not. The ranges of score of each question on corporate images after and before providing CSR information were 3.21-3.94 and 3.89-4.62, respectively. Also, the ranges of score of each question on repurchase intention after and before providing CSR information were 3.11-4.64 and 3.60-4.67, respectively. Thus, the result confirms that the previous studies' conclusion which explains CSR can shield consumers' negative attitude toward the company. The finding of this study emphasizes the importance of CSR activity to the companies in food industry and the need for making public awareness of CSR activity.

  • This paper represents the application of the 3D CAD Model data for 4D simulation and quantity estimation. These support the effective and practical use of 4D CAD model. By using and manipulating the 3D CAD model information, scheduling and quantity estimation could be developed more quickly and effectively. So the 3D CAD model information is made use of not only drawing a blueprint but also playing an important part of data integration platform. The scheduling module sets up the schedule generation logic that consists of period, priority of element arrangement, and time lag of floor placement. It sorts the working items as a priority of working process. And the quantity estimation module queries the material quantity of the structural elements according to the scheduling conditions. These two modules are developed using the 3D CAD model information and assist the function of 4D CAD model.

  • The purpose of this study is to reassert the important role of sound design in creating narrative space in films. The main focus is on re-interpreting Chion's sound space composition as a narrative structure. The sound design process has been analyzed to find that the physical properties of sound are purposely manipulated to create the layers of sound to be perceived by the audience in the same way as human perception and cognition of the actual reality work, eventually to create the cinematic reality. The hierarchy of the layers is determined by the importance of the narrative information contained in each sound, with the higher layers being appropriate to convey the information of the narrative, and the lower layers being efficient to deliver the emotion to the audience. With this idea, each of the Chion's space composition is explained as a distinctive area in telling a story with the separate narrative role from the others.

  • 'Sportainment' like Golfzon, which combines the elements of sports and entertainment have a lot of potential and development as new business items in the view of overcome many limitations such as time and place in real sports. For ultimately developing baseball simulation game as 'sportainment', this paper as the early stage suggests the system which can analyze pitching and swing. Unlike speed-gun measurement for moving ball, it uses sensor technology to take information of ball speed and movement and reproduces graphic screen based on the information collected from sensors with graphic technology. Hitter's swing and hit-ball can be measured in the similar way. This baseball simulation game is expected to develop as one of successful indoor spotainment businesses such as Golfzon.

  • 본 연구에서는 미래 기후변화 시나리오를 이용하여 우리나라의 미래 산림식생 분포 변화를 예측하고 이를 SWAT 모형에 적용하여 영산강호유역의 증발산량 변화를 분석하고자 하였다. 현 기상관측자료(1971~2000)를 이용하여 현재의 기후를 판정하고, 기상청에서 제공한 GCM(MIROC3.2)의 통계학적 다운스케일링으로 구성된 RCM 자료를 이용하였다. 산림식생의 분포는 임상도에 의한 현존 식생군락과 환경인자(강수량, 기온, 지형인자, 토양유기물 함량 등)간의 상관분석을 실시하여 상관관계가 높은 주요 환경변수들을 결정하고, 이들을 종속변수로 하는 다항로짓모형을 구성하여 추정하였다. 이 모형을 이용하여 미래의 주요 환경변수들을 입력, 미래 2020s, 2050s, 2080s의 우리나라 산림식생 분포를 예측하였다. 예측된 산림식생 분포를 적용하여 미래 증발산량을 분석하기 위해 남쪽의 따뜻한 지역으로서 활엽수림이 있는 영산호유역($3,455.0km^2$)을 선택하였다. 1998~2002 5년간의 유출량 자료를 이용 모형을 보정하였다. 모형의 검증은 보정 매개변수의 평균값들을 통해 2003~2008년 유출량을 모의 하였다. 예측된 미래식생분포를 이용하여 토지이용도를 재구축하였으며 재구축 결과 활엽수는 $715.2km^2$ 늘어나며 혼효림은 현재에 비해 2080s에 $167.1km^2$ 침엽수는 $548.1km^2$ 줄어드는 경향을 보였다. 영산호유역에서는 미래의 증발산량이 증가하며, 식생분포를 고려하였을 경우 2080s년에는 고려하지 않은 경우에 비해 약 4.52mm 감소하는 것으로 분석되었다.

  • SCA is proposed in order to operate various wireless systems in the single terminal platforms and uses the CORBA middleware to guarantee the platform-independence for software components. As the reconstruction demand is expanded in the software component to the logic level to many reasons, CORBA has to guarantee the independence of hardware on board. Accordingly. the characteristics depending on hardware board is ed. And the IDL-based interworking interface about the component has to be provided. In this paper, we described about local transport for guaranteeing the independency on the hardware board and the HAO Core for providing a coupling by the CORBA IDL identically with the other component. HAO produced at 2,900 logic cell size in average and provided the performance of the tens times than the software component. Through the use of HAO in the SCA-based development environment, it was naturally expanded to not only the software area but also the FPGA logic.

  • The purpose of this study is to analyze the factors influencing poverty in the elderly under the income maintenance, focusing on labor. Accordingly, a Panel Logit Analysis was conducted based on the 7th to 16th data of the Korean Welfare Panel. The analysis results are as follows. First, even if demographic, economic, and health variables affecting elderly poverty are controlled, National Pension and Special Occupational Pension among the income maintenance are negatively related to elderly poverty. On the other hand, it was found that the amount of Basic Pension and National Basic Living Security were positively related to poverty for the elderly. Second, it was found that if the elderly receiving national basic living security work, there is a high possibility of poverty. This raises the need to restructuring the Basic Pension, and suggests that it is necessary to combine the National Basic Living Security with the elderly job policy. Finally, in order to alleviate overall elderly poverty, it is suggested to rebuild the multi-pillar old-age income security system, including Basic Pension and Retirement Pension.

  • The purpose of this study is to investigate the current status and motives of buying second-hand clothing among university students and to suggest a plan to activate second-hand clothing transactions. In order to discover the effect of the buying motives on the purchasing of second-hand clothing, 112 university students who have purchased second-hand clothing over the past six months were surveyed and their responses were used for analysis. As a result of the analysis, it was found that design differentiation, habitual use, and economical factors had a meaningful effect on the purchase of second-hand clothes. Second-hand clothes have a positive environmental perception, but that perception did not impact the purchasing of second-hand clothes. It is necessary to raise the awareness and social movement around second-hand clothing and teach consumers the environmental benefits and sustainability of second-hand clothing. An activation plan for the second-hand clothing market is: 1. Proposes various market subdivisions that meet the characteristics and tastes of consumers that lead to the purchase of used clothing. In this study, two economic factors were found among the buying motives. The first is purchasing second-hand clothing at a very low price, and the second is finding luxurious expensive items or unique values at a lower price. Therefore, it is necessary to find various markets segments that suit consumer tastes by checking consumer characteristics and detailed factors. 2. Nurture second-hand clothing processing brands for the diversification of the second-hand clothing market. 3. There is an urgent need for quality classification, quality assurance, and the standardization of second-hand clothing. This study is meaningful in that it explored the possibility of having a positive effect on activating the second-hand clothing market.
