  • 부가처리시스템(Value-Added Processing System, VAPS)은 아리랑위성 영상자료 후처리를 위하여 개발되었으며 최근 VAPS의 성능 개선을 위하여 소프트웨어 버전과 하드웨어 사양이 변경되었다. 본 연구는 기존 VAPS(ver.1.0)의 성능 개선에 대해서 설명하고 개선된 VAPS(ver.2.0)에 대한 체계적인 성능 평가에 목적이 있다. 이를 위하여, 남한과 북한에서 실험지역(test-bed)을 선정하고 이들 지역에 대한 아리랑위성 2호, 3호 영상자료를 이용하여 자료처리 실험을 수행하였다. 결론적으로 VAPS(ver.2.0)는 정사영상과 모자이크영상 등과 같은 높은 레벨의 제품을 생성할 수 있는 능력이 있으며, 특히 그래픽처리장치(Graphic Processing Unit)를 사용하는 ver.2.0의 경우 자료처리 속도가 ver.1.0에 비해 최대 10배 이상 향상된 것으로 나타났다.

  • 본 논문에서는 확대영상의 화질을 향상시키기 위하여 영상의 곡면 특성을 활용한 효과적인 영상 확대 기법을 제안하였다. 제안된 기법에서 제시된 방법으로 영상의 단순 볼록 곡면 혹은 단순 오목 곡면을 효과적으로 추정하고, 단순 볼록 곡면 혹은 단순 오목 곡면으로 추정된 경우에는 확대하고자 하는 원본영상으로 역방향 사상된 좌표에서의 보간 값을 제안된 기법에서 제시된 효율적인 방법으로 계산하여 해당곡면의 특성을 잘 반영하는 보간 값을 구한 후 이를 확대영상의 보간 픽셀 값으로 하여 확대영상이 실제영상의 곡면 특성을 충실히 반영하도록 하였다. 또한 단순 볼록 곡면 혹은 단순 오목 곡면이 아닐 경우에는 역방향 사상된 좌표 주위의 기준 픽셀들의 영향을 더욱 정교하게 반영하도록 보간 값을 구하고 이를 확대영상의 보간 픽셀 값으로 한다. 실제 영상에 존재하는 단순 볼록 곡면 혹은 단순 오목 곡면의 특성을 더욱 충실히 반영하여 실제영상에 더욱 근접한 확대영상을 구성하도록 하기 위하여 위의 절차를 반복적으로 적용하여 확대영상을 구성하였다. 제안된 기법을 적용한 확대영상들의 PSNR(Peak Signal to Noise Ratio) 값이 기존의 기법들을 적용한 확대영상들보다 큰 것을 실험을 통해 확인하였다.

  • This study was carried out to examine the improvement plan by analyzing the characteristics of imported wastes, operation rate, and benefits of energy recovery for incineration facilities with a treatment capacity greater than 50 ton/day. The incineration facility capacity increased by 3,280 tons over 15 years, and the actual incineration rate increased to 2,783 ton/day. The operation rate dropped to 76% in 2010 and then rose again to 81% in 2016. The actual calorific value compared to the design calorific value increased by 33.8% from 94.6% in 2002 to 128.4% in 2016. The recovery efficiency decreased by 29% over 16 years from 110.7% to 81.7% in 2002. Recovery and sales of thermal energy from the incinerator (capacity 200 ton/day) dominated the operation cost, and operating income was generated by energy sales (such as power generation and steam). The treatment capacity increased by 11% to 18% after the recalculation of the incineration capacity and has remained consistently above 90% in most facilities to date. In order to solve the problem of high calorific value waste, wastewater, leachate, and clean water should be mixed and incinerated, and heat recovery should be performed through a water-cooled grate and water cooling wall installation. Twenty-five of the 38 incineration facilities (about 70%) are due for a major repair. After the main repair of the facility, the operation rate is expected to increase and the operating cost is expected to decline due to energy recovery. Inspection and repair should be carried out in a timely manner to increase incineration and heat energy recovery efficiencies.

  • The study aims to examine the relationships between service quality, experience value, relationship quality and behavior intentions. Validated measurements were identified from a literature review. The total of 309 valid respondents were used in this research. The measurement model and the conceptual model depicting hypothesized relationships were evaluated based on the 309 responses using confirmatory factor analysis and a structural equation modeling, accordingly. In addition, this study systematized the concepts, defined and tested the component scales of the relationship model between service quality, experience value, relationship quality and behavior intentions from the collected data, which helps to adequately identify the relationship between the factors in the model as well as the impact. The findings confirm that service quality influences experience values, relationship quality and purchase intention. Service quality, experience value, relationship quality and behavior intentions altogether are not well understood in current literature despite the important implication for managers, academicians and consumers alike. Contributes to a better fit between relationship marketing models and managerial practice in business markets. This study provides managerial implications regarding service quality and experience value so that firms and marketers can consult and apply. Managers should not only focus on the improvement of service quality but overall strategic planning.

  • Purpose: The purpose of this study was to verify influencing factors affecting service quality provided by caregivers working for the elderly with dementia. Methods: Data were collected using a self-reported questionnaire from 214 caregivers in a long-term care facility in D city. The data were analyzed with service quality, dementia knowledge, work value, and job performance confidence. For data analysis, the descriptive statistics, t-test, one-way ANOVA, Pearson correlation coefficients, and multiple regression were performed using SPSS/WIN 21.0 program. Results: There were significant differences in service quality depending on the health status. Factors influencing service quality were work value, and job performance confidence with R2 value of 38%. The highly influencing factors were work value, and job performance confidence. Conclusion: The results of this study indicate that the effort to improve the service quality of caregivers should focus on work value and job performance confidence.

  • In this paper, we consider the quality problem of black oxide process in casting for which Taguchi method is used. We explain simply the Taguchi method and existing problems in Black Oxide process. We analyze the problem by the quality improvement procedure proposed by Taguchi. The design factors and noises using cause-effect diagram are found, the experiment is made using orthogonal array. After ANOVA, the critical factors are determined and the optimal process condition is designed. After parameter design, we derive the tolerance levels. As a result of changing the levels of process parameters, the variance of quality characteristic was decreased by quarter and the average value was also decreased by half. We estimated the predictable profit of the improvement.
