본 연구에서는 UAV를 활용한 사진측량에서 지상 기준점 배치에 따른 정확도 분석을 수행하였다. 연구대상지역에 17개의 지상 기준점과 13개의 검사점을 설치하고 5가지 유형의 배치 형태를 만들었으며 검사점을 이용한 항공삼각측량의 성과분석과 산출물인 정사영상의 정량적, 정성적 분석 및 DSM을 이용한 공간분석을 수행하였다. 분석 결과 지상기준점 배치 시에는 삼각망 형태의 평면상의 배치형태도 중요하지만, 지형의 기복에 따른 지점의 높이 값을 고려하여 배치해야함을 확인하였다. 즉, 측량 대상 지역의 전체적인 평면상의 배치와 함께, 높이 값을 고려하여 지상기준점을 배치해야 더 높은 정확도를 확보할 수 있다.

합성보에 휨모멘트가 작용하면, 콘크리트 슬래브의 아랫면과 강재보의 윗면은 각각 인장력과 압축력에 의하여 팽창과 수축을 한다. 필연적으로 두 부재의 사이에서는 미끄러지려고 하는 수평전단력이 작용하게 되며, 이에 저항할 수 있는 전단 연결재의 역할이 매우 중요하다. 이 연구에서는 화약의 폭발력을 사용하여 강재보의 플랜지에 전단연결재를 고정하는 방법을 개발하였다. 개발 고정방법의 구조성능을 검증하기 위하여 보-기둥 접합부 실험과 유한요소해석을 수행하였다. 실험 및 해석결과를 기반으로 판단했을 때, 개발된 접합방식을 통하여 충분한 연성 및 강도를 확보할 수 있을 것으로 판단된다.

The degree of interaction is a very important factor determining stiffness, strength and deflection performance in the composite beam. Because this synthesis is made through the shear connector, the structural performance of the shear connector is very important. In this study, the connection method was developed using the driving pin to solve the problem of conventional welding connection method. To verify the structural performance of the developed connection method, the push-out test was performed and analyzed against numerical analysis results. Based on the results of the analysis, it is deemed that the structural performance can be obtained by joining the shear connection in proposed method.

The purpose of this study is to explore the mediator effect of the presidential candidate brand affiliated to the certain party toward enhancing the party brand equity and the presidential candidate brand value. In detail, firstly, the study attempts to identify the determinants of the party brand equity. Secondly, we clarify the factors of presidential candidate brand value. Finally, the paper testifies the proposed mediator model of the presidential candidate brand with respect to the impact of the belonging party brand equity in voting intention. Results show that the mediator effect of candidate brand exists between the affiliated party and the voting intention. In voting intention, the perceived quality of the party brand equity significantly influences on the candidate brand. Brand loyalty and Brand association of the party brand equity don't impact on the candidate brand significantly. In addition, the result proposes the all components of candidate brand value have significant impacts on voting intention. This paper is an initial attempts to regard the political parties and affiliated candidates in terms of brand marketing as the party brand equity and the candidate brand value respectively. With respect to better enhancing an approval rating, the study is proposed to the parties and candidates to-do list and direction of brand equity management.

A vendor selection problem consists of two different kinds of decision making. First one is to choose the best suppliers among all possible suppliers and the next is to allocate the optimal quantities of orders among the selected vendors. ln this study, a

Recently, China's economic development has been accelerated by its WTO entry and hosting Bejing Summer Olympic, so on. Many Chinese companies are facing more global competition, while they are growing faster. Therefore, in order to win the battle in the global market, they should improve their efficiency by implementing various management innovation tools such as 6 sigma. 6 sigma is a well-known methodology to improving management efficiency and has been implemented by many global companies. While a large body of research in the field of 6 sigma has been conducted and known in many countries such as USA, Japan, EU, and Korea, Chinese research papers on 6 sigma are still unknown. In this paper, we search, review and summarize the Chinese research papers. Based on this review, we propose the right direction of the 6 sigma research in China.

Service productivity is a brand new concept in the service industry, since it is quite different with conventional productivity. While the productivity in manufacturing is one of the quantitative measures for evaluating process efficiency, the service productivity include the nature of customer satisfaction as well as those of service process efficiency. Customer satisfaction, also called service quality in the service industry is one of the most difficult factors to measure quantitatively due to its intangibility. Hence it is also difficult to measure the service productivity correctly. It is hard to find the existed models for service productivity or related research papers in the literature. In this study, a new model which can be used to measure and evaluate the service productivity considering both the service quality and the productivity of service process is proposed. AHP, one of the well-known multiple-criteria decision-making methods, is applied to deal with both quantitative and qualitative factors in the model. The methodology and the procedures for measuring and evaluating service productivity are also presented.

A vendor selection problem consists of two different kinds of decision making. First one is to choose the best suppliers among all possible suppliers and the next is to allocate the optimal quantities of orders among the selected vendors. In this study, an integration of the technique for order preference by similarity to ideal solution (TOPSIS) and a multi-objective mixed integer programming (MOMIP) is developed to account for all qualitative and quantitative factors which are used to evaluate and choose the best group of vendors and to decide the optimal order quantity for each vendor. A solution methodology for the vendor selection model of multiple-vendor, multiple-item with multiple decision criteria and in respect to finite vendor capacity is presented.

이 연구의 목적은 고등학생들의 광물과 암석에 대한 개념 이해의 특징을 알아보는 것이다. 연구 목적을 위하여, 광물과 암석에 대한 개념 질문지를 개발하였다 질문지는 4개의 영역으로 총 12문제로 구성되어 있었다. 고등학교 10학년 학생 93명, 11학년 학생 119명을 대상으로 자료를 수집하였다. 수집된 자료의 분석을 통해 고등학생들의 광물과 암석에 대한 이해 수준 및 특징은 다음과 같이 나타났다. 전체적으로 고등학생들은 절반정도의 이해 수준을 보였으며, 10학년 학생은 화성암 영역에서, 11학년 학생들은 암석 영역에서 평균보다 약간 낮은 이해 수준을 보였으나, 광물의 녹는점과 관련된 특정 개념에서 매우 낮은 이해를 나타냈다. 둘째, 10학년과 11학년 학생의 이해수준은 대체로 비슷하여 과학적 개념 형성 비율이 유사함을 나타냈으나, 몇몇 문항에 대해서는 학년이 올라감에 따라 과학적 개념 형성 비율이 증가한 경우도 있었다. 그러나 학년이 올라갔음에도 통계적으로 유의하지는 않았지만, 현무암의 표면적 특징을 묻는 문항에서 오히려 비과학적 개념의 빈도가 줄어들지 않고 늘어나는 경향을 보인 것도 있었다. 셋째, 학생들의 과학적 개념 형성에 지구과학 교과에서 배운 개념뿐만 아니라 주변 과학교과에서 배운 개념이 광물과 암석 개념 형성에 도움을 준 것도 있었지만 오히려 방해된 것도 있었다. 이 결과를 통해 학생들에게 지구과학 교과에서 사용되는 특징적인 용어들에 대한 교육을 할 경우 타 교과에서 사용되는 의미와는 별도로 이해되어야 한다는 것을 염두에 두고 가르칠 필요성이 제시되었다.

Overlay parameter control of the semiconductor photolithography process is researched in this paper. Overlay parameters denote the error in superposing the current pattern to the pattern previously created. The reduction of the overlay deviation is one of the key factors in improving the quality of the semiconductor products. The semiconductor process is affected by numerous environment and equipment factors. Through process condition prediction and control, the overlay inaccuracy can be reduced. Generally, three types of process condition change exist; uncontrollable white noise, slowly changing drift, and abrupt condition shift. To effectively control the aforementioned process changes, control scheme using adaptive deadband is proposed. The suggested approach and existing control method are cross evaluated through simulation.

The impregnated activated carbons were prepared by the incipient wetness method with the contents of KIO3 varied from 1.0~10 wt% as the impregnation material. The specific surface area and micropore volume of the rice hulls activated carbon were 2,600~2,800 m2/g and 1.1~1.4 cc/g, respectively. With increasing the contents of impregnation materials, the surface area and micropore volume decreased by 3~21%. However, The amounts of hydrogen sulfide adsorbed increased by 2.1~2.8 times depending on the impregnation content. The optimum contents of KIO3 were 2.4 wt%. Although the breakthrough time and adsorption capacity of hydrogen sulfide decreased with increasing temperature in the case of the unimpregnated activated carbons, they increased by 1.2~ 3.2 times for the case of the impregnated activated carbons. The optimum aspect ratio(L/D) was 1.0 and the adsorption amount of hydrogen sulfide enhanced with increasing the gas flow rate. The regeneration temperature was determined as 400℃ from the TGA experiment. The adsorption capacity of hydrogen sulfide with the impregnated activated carbon decreased gradually as the regeneration continued. The hydrogen sulfide adsorption amount of the regenerated activated carbon up to 4 times was still higher than that of the unimpregnated activated carbon.

Activated carbons with high surface area of 2,600 m2/g and high pore volume of 1.2 cc/g could be prepared by KOH activation of rice hulls at a KOH:char ratio of 4:1 and 850℃. In order to increase the adsorption capacity of hydrogen sulfide, which is one of the major malodorous component in the waste water treatment process, various contents of Na2CO3 and KIO3 were impregnated to the rice-hull activated carbon. The impregnated activated carbon with 5 wt.% of Na2CO3 showed improved H2S adsorption capacity of 75 mg/g which is twice of that for the activated carbon without impregnation and the impregnated activated carbon with 2.4 wt.% of KIO3 showed even higher H2S adsorption capacity of 97 mg/g. The improvement of H2S adsorption capacity by the introduction of those chemicals could be due to the H2S oxidation and chemical reaction with impregnated materials in addition to the physical adsorption of activated carbon.

대량생산체제를 위주로 했던 산업혁명 초기에는 원가계산방식이 비교적 수월하였다. 생산에 투입된 비용을 그대로 생산량으로 나누기만 하면 되었고 이 수치를 그대로 원가라고 간주하여도 기업이 존속하는데는 아무 영향이 없었다. 물론 이 때에도 간접비라는 것은 존재하였으나 그 비중이 미미했기에 이를 무시하여도 되었던 것이다. 그러나 그 때와 달리 지금은 기업환경은 다품종 소량생산, 고객 주문 생산 등의 다양한 형태로 변화되어 왔으며 유연생산시스템, 적시생산시스템 등과 같은 새로운 경영기법 및 생산관리 기법이 발달함에 따라 그간 무시되어 왔던 간접비가 오히려 직접비보다도 많아지는 현상이 생기게 되었다. 그래서 증가하는 간접비를 효과적으로 제품이나 서비스에 배부하여야 하는 필요성에서 연구가 시작되었고 그 결과로서 나온 원가계산방법이 활동기준원가계산시스템이다. 우리 나라에는 90년대 초반에 도입되어 여러기업이 시스템을 구축한 상태이며 이에 대한 사례를 연구한 논문도 발표되었다. 활동기준원가 계산시스템이 기존의 원가계산시스템보다 더 정교하다는 것은 많은 이미 많은 연구들에서 입증이 되었지만 그래도 실제 시스템의 구축에 있어서는 아직도 많은 연구과제가 남아있다. 본 연구는 시스템의 구축과정에서 핵심과정으로써 반드시 거쳐야 하는 활동분석단계에 관심을 두고 활동분석과정을 가능한 적은 비용으로 빠르게 수행하기 위한 방법을 모색하였다. 그 방법으로 선택한 것이 기존의 기업보유자료를 이용하여 활동분석을 수행하는 것으로 비록 활동분석데이터의 신뢰성에는 조금 부족한 면이 있을 수 있으나 기업보유자료가 활동분석과 개연성이 있음을 제시하고자 하였다.

With industrial development, the use of electrical and electronic products made of low-specific-gravity and easyprocessing plastics has increased. As these products have been abandoned, environmental problems, such as Dioxine and Furan, have begun to arise. Accordingly, through long-time reviews and discussions, the EU has implemented the Restriction of Hazardous Substances (RoHS) and Waste Electrical and Electronic Equipment (WEEE) regulations. Additionally, the Stockholm Convention was adopted in April 2011 for wastes containing brominated flame retardants. Therefore, the Basel Convention issued technical guidelines on environment-friendly treatment for wastes containing brominated flame retardants. For Korea to respond to both the conventions and changing trends in international persistent organic pollutant (POP) management, proper management and treatment plans suitable to Korean circumstances are required. In this regard, the study identified domestic and international trends in environmental regulations and usages, obtained fundamental data for the management of wastes containing brominated flame retardants, and investigated the current status of waste generation in Korea. Based on the results, six target samples were selected and evaluated to see if they were heat-treatable through content analysis, three-component analysis, element analysis, calorific value analysis, and thermogravimetric (TGA) analysis. The results of the analyses were used to make a lab-scale incineration reactor, and the results of the TGA analysis became the basis for setting the incineration temperature ranges for experiments. After incineration, five general air pollutants (O2, CO, CO2, SOx, and NOx) and three components of BRFs in the emission gas and flooring were analyzed to identify if the PBDEs in wastes can be destroyed in a stable and environmental manner during heat treatment.

Torrefaction is a treatment which serves to improve the properties of biomass in relation to thermochemical processing techniques for energy generation. In this study, the torrefaction of sewage sludge, which is a non-lignocellulosic waste was investigated in a horizontal tubular reactor under nitrogen flow at temperature ranging from 150-600℃. The torrefied sewage sludge products were characterized in terms of their energy yield, ash content and volatile fraction. The energy and mass yields decreased with an increase in the torrefaction temperature. The pelletization and the combustion characteristics of the torrefied sewage sludge was studied in isothermal and non-isothermal conditions.
