In this study the followings are investigated; the differences of the developers D-9 and D-72 and the change of gamma (γ) by development-time, the change of the characteristic curves by reversal and the mixing-rates and exposures of the blue-filter, the green-filter, and the red-filter. The best result was made possible when D-9 developer was developed at 30 degrees for one minute and fifty seconds with gamma (γ) 4.0 standard in tone-separation. The similar result was also made possible when D-72 developer was developed at 25 degrees for three minutes. The color-posterization which has the same effects of posters can be used for the fields of arts of arts and advertisement.

디지털 사진 출력물의 변퇴색에 관한 연구

임양환 한국사진학회 2005 AURA Vol.0 No.12

This study is about research on the discoloration of photograph images taken by digital cameras. The discoloration accured in not only light faded images caused by light but also in dark faded images caused by temperature and humidity. Digital images have checked off their density and characteristic CIELAB. According to this research light fading has effected on the chroma in digital images and dark fading has effected on the hue of digital images. The density in digital images was in low concentration. Furthermore, this experiment has clarified that the dark fading caused yellow stain ondigital images. As a result, the images printed by the raser chemical process with silver process had the best persistence. Also pigment process had superior persistence.

This study explores the conditions under which consumers adopt wearable devices. The study focuses on the attractiveness of the product that consumers can perceive. This study was implemented to find out what factors influenced the consumers to perceive the attractiveness and value of the product. The factors include the benefits and costs of the product. The consumers' wants for the product was included under personal factor. The synergy effect of related product was classified circumstantial factor. The outcomes derived from the postulating and verifying hypothesis are as follows. First, the attractiveness of the product that the consumers perceive has a positive effect on perceiving the attractiveness of the product. Second, the benefits of the product that the consumers feel have a positive effect on the value of the product in a meaningful way. Third, the consumers' perception of the wants for the product have a significant effect on perceiving the value and attractiveness of the product. Fourth, the consumers' perception of the synergy effect between the wearable device and the smartphone did not affect the value of the product in a significant way, but did have a significant effect on the attractiveness of the products.

In this study, I researched whether consumers would adopt artificial intelligence speakers. A study was conducted on the motivations that arise when consumers want to use artificial intelligence speakers. Key motivational factors include needs and wants, and emotion is also included in the hypothesis as influencing the intended use. These factors have modeled the motivational process in which consumers want to use artificial intelligence speakers. In the empirical study, the survey was conducted and the survey data was analyzed by applying the method of analysis of the structural equation model. As a result of empirical research, consumers' expectations to meet their general needs for artificial intelligence speakers affected their expectations to meet their wants and their favorable perceptions. And consumers' expectations of meeting their quasi-desire for artificial intelligence speakers have affected their expectations of meeting the wants and affected their perception of favorability. Finally, consumers' expectations for satisfying their wants and their perception of favorability affected their intention to use artificial intelligence speakers. The implications of this study is that it helps to formulate strategies for information technology products with combined functionality. The specific components of motivation can play an important role in increasing consumers' intention to use artificial intelligence speakers.

사진화상의 보존에 관한 연구 : 황산은법에 의한 필름과 인화지의 잔류티오황산염의 반응

임양환 한국사진학회 2000 AURA Vol.7 No.1

사진화상은 처리방법과 보존환경에 따라서 변색과 퇴색을 일으킨다. 우리나라의 사진화상의 변퇴색의 유형과 변화의 정도를 조사한 결과, 정착과 수세처리의 오류에 의한 필름과 인화지의 황변색과 은석출 유형이 대부분을 차지하였다(1). 본 실험에서는 그 원인이 되는 불충분한 정착 처리 및 수세처리를 한 필름과 인화지를 황산염법을 이용하여 잔류 티오황산염의 반응을 비교, 검토하여 사진화상의 보존에 적합한 정착과 수세처리 방법을 찾고자 한다. 그 결과, 필름의 경우, 경막정착액에 비해 비경막정착액을 사용했을 때 잔류 티오황산염의 제거 능력이 좋았으며, 유수로 수세한 것에 비해 수세촉진제를 사용한 것이 잔류 티오황산염의 제거능력이 뛰어났다. 그리고 피로해진 정착액을 사용한 것일수록 잔류 티오황산염의 양이 증가하는 것을 알 수 있었다. 인화지의 경우에는 RC 인화지가 FIBER에 비해서 잔류 티오황산염의 제거능력이 우수했고, 정착액의 피로도가 증가할수록 잔류 티오황산염의 반응이 증가하였다. FIBER 인화지의 경우, 수세촉진제를 사용한 것과 유수로 처리한 것이 생각 한 것과는 달리 큰 차이가 없는 결과를 얻었다. Photographic image results in discoloration and fading according to its process and preservation. Discoloration and color fading of Korean photograph image were mostly due to yellow discoloration or silver extraction of film and paper, which resulted from wrong fixation and wrong washing process. This experiment aims to research the method of suitable fixations and washing process for preserving photographic image fore by comparing films and papers which was wrongly processed because of insufficient fixations and washing and by analyzing their reactions to the remaining sulfuric acid. As a result, as to films, an effect of removing the remaining sulfuric acid by non-hardening solution for fixing was better than by a hardening solution for fixing, and was much superior by using an accelerator for washing to by using streaming water. And the older and more tired the fixing liquid was, the more the quantity of sulfuric acid increased. As for printing paper, an effect of removing the remained sulfuric acid was higher on RC paper than on FIBER paper, and the more tired the fixing liquid was, the more the reaction to the remaining sulfuric acid increased. Contrary to what was expected, however, it was concluded that on FIBER paper, the reaction to it made little difference between when using an accelerator for washing and when using streaming water.

We made experiments in Light Fading on light and Dark Fading on temperature in order to see how color and gradation will vary when color films and color paper on sale or present vary an influence of light, temperature, and humidity. And we made an experiment in Dark Fading after putting color paper and color film made by Yellow, Magenta, Cyan, Neutral Density 1.0 ± 0.1 in the incubator Temperature and Humidity Test Chamber, and also made an experiment in Light Fading by using a fluorescent lamp, direct sunlight, and projector. As the result of those experiments, we concluded that we could measure, in a given quantity, Light and Dark Fading by the variation of color density and the color variation using CIELAB color system.
