주위 광원에 화이트 밸런스 된 카메라로 촬영한 피사체의 RGB신호를 D/sub 65/ 광원하의 표준 디스플레이 상에서 느끼는 자극치 L₁M₁S₁값과, 실제 촬영 장소에서 눈이 충분히 주위 조건에 색순응 된 후 피사체에 대해서 느끼는 자극치 L₂M₂S₂값은 다르게 느껴진다. 이는 LMS 시세포의 파장별 감도특성과 카메라의 RGB 칼라 필터의 파장별 감도특성이 다르기 때문이다. 또한 주위 광원의 종류와 밝기에 따른 물리적인 자극 변화에 대해서 카메라의 경우는 RGB 각 채널의 이득이 선형적 변화를 가진다. 그리고 눈의 경우는 LMS 시세포의 감도가 비선형적 특성을 가지기 때문에 색감의 차이를 발생시킨다. 본 논문에서는 촬영시의 주위 조건에서 원 피사체를 직접 볼 때 느끼는 색감을 표준 시환경인 D/sub 65/ 광원하에서 화이트밸런스가 D/sub 65/인 디스플레이를 통해 피사체 이미지를 볼 경우에 동일한 색감을 느끼도록 하는 알고리즘을 제안한다. 제안된 알고리즘을 이용하여 표준 조건하에서 디스플레이 하였을 때 촬영 조건에서의 등색감을 재현할 수 있다.

The purpose of this study is to examine the family reproduced by fishing village episode 1. (삼시세끼, three meals a day), which attempted a new type of entertainment termed an experiential real entertainment documentary, was produced in a total of nine episodes from October 2014 to March 2015. This study analyzed fishing village episode 1, which was aired in 2015 and obtained the highest ratings, using narrative analysis. The development of was consistently structured in the order of 'wake up - free time - breakfast - lunch - dinner - rest - sleep'. The character construction of the characters was created through the arrangement of a main space and a main role for each of the characters. Also, the characters were in relationships through which they became the background of each other. Therefore, in the family reproduced by , a mother without a father and a father without a mother are impossible. Despite that all the cast members were male, the subtitles constantly gave them the roles of 'housewife/wife/mother', 'father/husband/dad', and 'son', while actively blocking the image of a homosexual family. The family created as such was a family with children, a family with both mother and father, a heterosexual family, and a nuclear family. As a result, reproduced the typical modern family, normal family, and standard family.

This study, the exchange value of the car after the repair, which affects the valuation elements and repair characteristics factors were investigated. Based on this specific accident damaged condition of the car, repair range, repair methods, repair costs, market transactions, taking into account the vehicle's depreciation appraisal method is proposed.

A $32{\times}32$ pixels foveated (linear-polar) structure retina chip with the function of local-light adaptation for edge detection has been designed and fabricated using CMOS technology. Human retina can detect a wide range of light intensity. In this study, we use the biologically-inspired visual signal processing mechanism that consists of photoreceptors, horizontal cells, and bipolar cells in order to implement the function of edge detection in the retina chip. For a local-light adaptive function, the size of receptive field is changed locally according to the input light intensity. The spatial distribution of sensing pixels in the foveated retina chip has the advantages of selective reduction of image data and good resolution in central part to carry out the elaborate image processing with still enough resolution in the outer parts. The designed chip has been fabricated using standard $0.6\;{\mu}m$ double-poly triple-metal CMOS technology and optimized using HSPICE simulator.

Due to recent changes in government policy, officetels have received attention as alternative assets, along with the uplift of office and apartment prices in Seoul. However, the current officetel price indexes use small-size samples and, thus, there is a critique on their accuracy. They rely on valuation prices which lag the market trend and do not properly reflect the volatile nature of the property market, resulting in 'smoothing'. Therefore, the purpose of this paper is to create the officetel price index using transaction data. The data, provided by the Ministry of Land, Infrastructure and Transport from 2005 to 2020, includes sales prices and rental prices - Jeonsei and monthly rent (and their combinations). This study employed a repeat sales model for sales, jeonsei, and monthly rent indexes. It also contributes to improving conversion rates (between deposit and monthly rent) as a supplementary indicator. The main findings are as follows. First, the officetel price index and jeonsei index reached 132.5P and 163.9P, respectively, in Q4 2020 (1Q 2011=100.0P). However, the rent index was approximately below 100.0. Sales prices and jeonsei continued to rise due to high demand while monthly rent was largely unchanged due to vacancy risk. Second, the increase in the officetel sales price was lower than other housing types such as apartments and villas. Third, the employed approach has seen a potential to produce more reliable officetel price indexes reflecting high volatility compared to those indexes produced by other institutions, contributing to resolving 'smoothing'. As seen in the application in Seoul, this approach can enhance accuracy and, therefore, better assist market players to understand the market trend, which is much valuable under great uncertainties such as COVID-19 environments.
