In this paper, we propose dead pixel detection and compensation method using nonlinear estimator for infrared camera. Infrared camera has dead pixel that is abnormal output values due to complex factors such as manufacturing process, electronic parts and so on. Dead pixels are able to affect detecting a small target. So, It needs detection and Compensation process. However, after Compensation, some dead pixels are remained and detected by the human. They are soft dead pixel. The key idea of this proposed method, detecting soft dead pixels, is that design a nonlinear estimator using image data characteristics. This propose is able to not only detect soft dead pixels but also pixel Compensation that reflects infrared camera output characteristics well.

대한민국의 낚시산업은 레저활동을 즐기는 인구 증가로 인해 매년 급성장하고 있으며 이에따라 규모가 큰 9-10톤급 낚시어선 의 수는 매년 늘어나고 있다. 현재 운항 중인 낚시어선은 낚시 활동 중 유류비 절감과 엔진 발생 소음 저감을 위해 엔진을 정지하고 배터리를 이용하여 선박의 필수장비를 운영하고 있다. 하지만 배터리의 방전으로 인한 엔진 시동불량 등으로 인해 해상에서 표류되는 사고가 매년 꾸준히 발생하고 있으며, 이는 대형 인명사고로 이어질 수 있다. 본 연구에서는 낚시어선의 안전확보를 위해 태양광 보조전원 설치를 제안하고, 9-10톤급 선박을 대상으로 선정하였다. 대상선박의 태양광 발전설비 공간 확보 가능성을 확인하였으며, 태양광 발전설비의 적용을 검증하기 위해 조업 중 필요한 필수 부하량을 계산하고 전력분석프로그램을 통해 태양광 발전시스템을 모델링하였다. 모델링 된 태양광 발전시스템에 우리나라의 월별 수평면 평균 일사량을 적용하여 낚시어선의 태양광 보조발전장치 적용에 관한 타당성을 입증하였다.

The aim of this study was to determine the therapeutic effects of beauty care on negative mental health, including stress and depression. Nail care, massage care, and makeup were used as programs for beauty therapy. Qualitative research was conducted with six female participants over five-month period. After interviewing the subjects in advance, beauty care treatments were performed every week 4 weeks in the following order: nail care, massage, and makeup. The results are as follows, First, the participants perceived beauty care in the form of 4 concepts: “courtesy in social life,” “investment in oneself,” “self-satisfaction,” and “self-care.” Second, the effects of beauty therapy were categorized as “psychological effects,” “confidence,” “behavioral changes,” “evaluation of others,” and “positive social effects.” Third, each subject showed different psychological effects during the process when the function of the therapy took effect through the beauty care treatment. It was confirmed that confidence levels increased as a result of treatment through the process of becoming re-aware of oneself. Positive statements from the participants included: “I want to go out,” “I have become kind and positive to others,” “I have become more active in a given task,” and “It seems that my work ability is improving.” Finally, t-test results for selfesteem, depression, and stress showed there were significant differences in self-esteem and depression. This confirmed that self- esteem increased, and depression decreased after the beauty care treatment.

Forming perceptions and having experiences through digital media is becoming more common than having in-person relationships in digital media environment. This study, which was conducted when Fashion Week transitioned to a digital platform in 2020, focuses on fashion shows that are announced through social media. The purpose of the study is to explore how traditional fashion media change through social media and what their media characteristics are from the perspective of remediation, which has been suggested by Bolter and Grusin (1999) as the logic of change in the new media. The results of the case analysis in this study, based on the definition and logic of remediation outlined through a literature review, are that social media fashion shows are remediated from traditional fashion shows in the manner that they are represented, improved, refashioned, and absorbed. The characteristics of remediation expressed in social-media-based fashion shows were derived from repurposed video content, improved the elements of fashion shows to express the shows in various ways, expanded places within the fashion shows, and decontextualized and visually flattened spatial discontinuity, and from genre transitions and perceptual shifts. Socialmedia- based fashion shows are becoming a tool to renew the fashion experience and views of fashion and strengthen the authenticity of the brand by interacting with the audience, improving on the spatial limitations of traditional fashion shows, and diversifying fashion presentation methods.

Red beet roots (Beta vulgaris L.)는 천연색소로 붉은 색 계열의 betacyanins은 75-95%의 betanine와 이성질체인 isobetanine 15-45%으로 존재한다. 본 연구는 비트레드를 사용한 식품에 대해 HPLC-DAD를 이용하여 지표성분인 betanine 및 isobetanine에 대해 분석법을 확립하였으며, 유효성 검증을 위해 직선성, 검출한계, 정량한계, 정확성, 정밀성, 측정불확도를 측정하였다. 캔디류, 빙과류, 코코아 가공품의 matrix에 적용하여 matrix matched calibration법 을 사용하였으며 R2이 0.9998 이상으로 높은 직선성을 보였다. 검출한계와 정량한계는 각각 0.16-0.32 mg/L, 0.48- 0.97 mg/L으로 확인되었다. 분석법의 정확성 및 정밀성을 검증하기 위해 intra-day 및 inter-day 반복 실험 결과, 회수율은 96.0-103.1 %, 100.0-102.2 %이였으며, RSD는 0.5-3.3 %, 0.9-3.8 %로 산출되었다. 측정불확도는 매트릭스 및 측정 농도에 따라 1.71-12.43%로 평가되었다. 또한, 확립된 분석법의 적용성 검토를 위해서 비트레드 색소를 사용한 가공식품 26종을 분석한 결과, betanine과 isobetanine 을 정량 할 수 있었다 (8.4-3,823.4 mg/kg).
