AHP 기법을 적용한 민간 기업의 신재생에너지 평가항목에 대한 연구

홍정만(Jungman Hong) 에너지경제연구원 2011 에너지경제연구 Vol.10 No.1

본 연구에서는 민간기업의 신재생에너지 투자 의사결정과 관련된 주요 평가항목을 도출하고, 각 항목의 가중치를 분석하였다. 평가항목 가중치 분석을 위해 신재생에너지 관련 전문가 그룹의 특성에 따라 사업투자, 시장 분석, 에너지운영 전문가 그룹으로 나누고 각 전문 분야에 따른 가중치 특성과 차이점을 분석하였다. 신재생에너지 투자 의사결정 관련 7개의 평가항목을 도출하였고 각 항목에 대해서는 전문가 그룹들을 대상으로 AHP(Analytic Hierarchy Process)기반의 쌍대비교 설문을 실시하였다. 설문 결과 경제성, 정부 정책, 설비투자 규모 관련 항목이 높게 평가되었다. 또한, 전문가 그룹별 평가항목 가중치가 서로 다르다는 점을 확인할 수 있었는데, 기술, 설비투자규모, 발전에 대한 통제 관련된 평가항목의 가중치 차이는 통계적으로 의미 있는 수준이었다. 이러한 차이점 분석을 통해 민간부문의 신재생에너지 확산의 한계와 향후 개선 방안에 대한 시사점을 제시하였다. In this study, investment criterions concerning renewable energy investment in private sector are driven and the importance weight of each criterion is analyzed. To analyze the importance weight, 3 expert groups(renewable energy business expert group, researcher, utility operation expert) are formed with the consideration of expert's expertise. The difference of importance weight from each expert group is analyzed. AHP(Analytic Hierarchy Process)-base survey was carried with 7 investment criterions for renewable energy investment. Importance weight for economic related investment criterion has the highest weight, 20.72%, and government policy and investment money related criterion are also evaluated with high importance weight. In the resulting importance weight, expert group considered the different importance weight for each investment criterion. The differences in criterion related to technology, controllability of renewable energy and investment money related are statistically significant level. By analyzing these differences, the limit of renewable energy investment in private sector is considered and implications for future improvement are presented.

논문 : 디지털 카메라 이미지 센서의 구조에 따른 재현성 연구

홍정의 ( Jeong Eui Hong ) 한국사진학회 2006 AURA Vol.0 No.15

This study investigates into the image reproductivity of digital cameras, comparing the Bayer pattern, the type most widely used for image sensor, with the Foveon X3 type, developed by the Foveon Inc. to match the human sight mechanism, and the Super CCD Honeycom type of the Fuji Films. For analysis, Canon 1DS, Fuji S3 Pro, Kodak DCS Pro SLR/N, Nikon D200, and Sigma SD10 were chosen as research objects and KIIMA Image Evaluation Test Target (QA-3), Kodak Gray Scale (Large) Q-14, Macbeth Color Checker and Kodak Color Control Patches Q-14, and Kodak Gray Card / Black White Card, as model subjects, in order to determine their image sensor`s reproductivity, regarding color reproduction, resolution, sharpness, dynamic range, gradation, and latitude. To measure the spectral resolution, Kodak Wratten Gelatin Filter No. 29, 47, and 61 were used in order to attain the spectrum of a visible ray. For color reproduction, Imatest-1.6.16 is used. The result of this study showed that reproductivity for Super CCD Honeycom and Foveon X3 was not as good as expected, but showed possibilities for development. The old Bayer pattern also needed much improvement in reproductivity. It can be inferred that the merits and demerits of Super CCD Honeycom and Foveon X3 will be at least partly useful in developing digital camera`s productivity in the future.

베이커리를 위한 LED 조명과 배경색에 관한 연구

홍정인(Jung-In Hong),박영경(Yung-Kyung Park),서민정(Min-Jung Seo) 한국색채학회 2010 한국색채학회 논문집 Vol.24 No.1

2000년 이 후 국내 베이커리 시장의 규모가 크게 팽창함에 따라 사업 역시 다각화되어 왔다. 이중 베이커리의 ‘조명(Light)과 색채(Color)"는 고객들의 관심을 집중시키고 구매력을 증가 시킬 수 있는 중요한 요소이다. 따라서 본 연구에서는 위의 두 가지 중요한 점을 연구하기 위한 작업으로서, 우선 LED 조명 아래서 육안으로 보았을 때 YR계열 빵의 색상이 가장 맛있어 보이는 조명색을 연구하였다. 그리고 단계별 실험으로 맛있어 보이는 최적의 조명을 선택한 후 그 조명 아래에서 빵의 바닥면인 배경색의 선호색을 연구하였다. 연구는 크게 네 가지 단계로 나누어 실험하였다. 제1단계는 맛있어 보이는 빵을 위한 조명을 찾기 위해 다양한 LED 조명하에서 촬영한 이미지를 서열에 따라 선택하는 실험(Pair comparison experiment)을 하였다. 제2단계 실험은 제1단계 실험의 결과에서 상위 3위 안에 든 조명을 ㏓를 변경하여 가장 적합한 조명을 최종적으로 결정하였다. 제3단계는 최종적으로 결정된 조명아래에서 빵이 맛있어 보이는 바닥의 배경색을 10가지 색상(Hue)에서 선정하였다. 마지막으로 제4단계 실험에서는 배경의 색상(Hue) 실험 에서 결정된 색상의 톤(Tone)을 11단계로 나누어 실험하였다. 제1단계와 제2단계 조명 실험 결과 번호 B124번의 LED 조명이 선정되었다. 이 조명아래에서 제3단계와 제4단계 실험이 진행되었다. 선정된 1위 조명은 실제 빵의 색보다 채도가 다소 높으며 R계열의 색상으로 이동하였다. 그리고 이 조명아래서 P/Lgr의 배경색에 놓인 빵이 더욱 맛있어 보여 선호 된다는 것을 알 수 있었다. In accordance with the large expansion of the domestic bakery market since 2000 year, the bakery business has been also diversified. In connection with the situation "Lighting and color" of bakeries have been important elements that could become major interests of customers and increase purchasing power. Therefore, this study is designed to find out the most appetizing bread with naked eye under the Light Emitting Diode lighting. Moreover, we have researched the preference color of the background under this lighting after we choose the most ideal lighting by experiments by step. The research experiments have been divided into four steps; At the 1st step, we conducted a pair comparison experiment which selects its image under various Light Emitting Diode lighting to find the most appetizing bread in order of importance. For the 2nd step, we finally deiced the best suitable lightings that rank within the highest 3rd positions resulting in changing the 1st step experiment to ㏓. The 3rd step, we chose the background color in 10 Hue that have made bread appeared the most appetizing under the finally decided lighting. Finally, the 4th step experiment was divided by 11 tones that decided Hue under the 3rd experiment of background color. No. B124 resulting from the 1st step and the 2nd step lighting experiments that were chosen in the 3rd step and the 4th step experiments proceeded under this lighting. And P/Lgr (Purple/Light Grayish Tone) which is the most appetizing background color under the selected lightings are chosen by the result of these two experiments. Under the selected 1st lighting Chroma has looked higher than the actual color of bread and changed to the color of R order. Moreover, this bread color has appeared more appetizing under the background color of P/Lgr to cause bread preference.

Purpose: This study was done to examine the intervention effects on the family of a family education program for pathological gamblers based on Community Reinforcement and Family Training (CRAFT). Methods: A quasi-experimental, nonequivalent control group pretest-posttest design was used. The participants were 44 families of pathological gamblers from G center in Gyung-gi Province and 5 Gam-Anon groups in Seoul City and Gyung-gi Province. The experimental group (n=22) attended the 6 weekly 2 hour-long CRAFT family education program. The control group (n=22) attended the 12-step program of Gam-Anon. Data were collected from November, 2011 to May, 2012. Results: Compared with the control group, the experimental group showed significant decrease in depression (p=.001) and state anger (p=.039). There were no significant differences between groups in the level of interpersonal communication, trait anger, the mode of anger expression and self-esteem. Conclusion: Findings from this study suggest that the CRAFT family education program is effective in decreasing depression and state anger in families of pathological gamblers.
