목적: 본 연구는 COVID-19의 대유행 동안 20~30대 성인을 대상으로 컴퓨터시각증후군 (CVS, computer vision syndrome) 관련 눈의 자각증상과 시력 관련 불편감을 파악하고, 눈 건강을 위해 사용하는 예방법을 알아보고자 하였다. 방법 : 2021년 12월부터 2022년 2월까지 안경 또는 콘택트렌즈 처방과 상담을 위해 일개 안경원에 내원 했던 20~30대 성인 중에서 전신질환 및 안질환, 안과적 수술 경험이 없는 150명을 대상으로 하였다. 연구도구는 대상자의 일반적인 특성(3문항), CVS 자각증상(16문항), 시력 관리(2문항), 눈의 조절기능 이상(2문항), 청색광 차단 안경사용(2문항), 근거리교정(1문항)으로 총 26문항으로 구성된 설문지를 이용하였다. 결과 : 전체 대상자들의 CVS 자각증상은 “눈물이 많이 발생한다”가 109명(72.7%)으로 가장 높은 빈도를 보였 고, 그다음은 “눈이 아프다”가 104명(69.3%)으로 나타났다. CVS 자각증상 중 시력 관련 자각증상은 “사물이 흐 려보인다”가 106명(70.7%)으로 가장 많았다. 시력 관리방법으로는 “시력의 저하를 느껴서”가 105명(70.0%)으로 가장 많았고, 청색광 차단 안경 사용하는 대상자는 150명(84.7%)으로 80% 이상의 대상자들이 기능을 넣어서 사 용하고 있다. 결론 : CVS 자각증상 16문항 중 14문항에서 50% 이상으로 나타났다. 청색광 차단 안경을 사용하지 않는 대상 자는 CVS 자각증상 중 시력과 관련된 “시력이 나빠지는 것 같다”가 69.6%로 가장 높게 나타났다. COVID-19 대 유행 동안 자각적인 불편증상과 시력저하를 호소하는 대상자가 높게 나타나고 있다. 따라서 안경처방 시 생활환 경, 사용시간 및 자각적 증상에 대하여 문진이 필요하다고 생각된다.

The objectives of this study are to explore the information source, assessment, and preferred styles of 3D virtual influencers(VI), to investigate the expected impact of advertisements with 3D VIs on brands, and to explore ways of expanding the use of 3D VIs. In-depth interviews with 40 males and females in their 20s and 30s were conducted and qualitative data were analyzed. The study results are summarized as follows. First, the information source of the 3D VI was SNS, acquaintances, and broadcasting. Second, 3D VIs were considered positively due to their attractive appearance, wide utilization, innovative use, freshness, separation from private identity, and time and cost savings, while considered negatively due to their unrealistic appearance and antipathy against replacing a person’s role. Third, the preferred appearance styles of the 3D VI differed according to the level of virtuality although the majority of interviewees preferred similar looks to real people with low virtuality. Fourth, diverse image qualities such as innovative, differentiated, trendy, high-value, professional, and future-oriented were considered as transferred to the brand advertised by 3D VIs. Fifth, advertisements with 3D VIs may help build positive perceptions of advertised brands that may lead to purchase behaviors for some consumers. Lastly, to expand the use of 3D VIs, the specific advantages of virtual models should be maximized with consideration of how to implement a variety of body types and images of models. Findings present an important foundation to generate strategies to better apply 3D VIs to the fashion market.

In this study, the Korea National Health and Nutrition Examination Survey in 2016 examined the nutrient and food intake of women in their 20s and 30s according to the number of meals a day, and the results were as follows: The study included 256 women in their 20s and 474 women in their 30s.

The vitamin A and C were eating less than the recommended intake in all meals. In the case of minerals, calcium was taken less than the recommended intake in all meals, but sodium was taken above the goal intake in all groups. Women in their 20s and 30s must reduce their intake of saturated fatty acids and sodium, and increase their intake of vitamins A, C, calcium, and potassium.

The study purpose was to investigate the jacket-fit satisfaction level of men in their 20s and 30s, using body-scanning data and a questionnaire. Thirty-five men were scanned using a 3D body scanner. The participants were divided into three groups (Small, Medium, and Large) based on their chest-circumference measurement. Their levels of satisfaction with the fit of their tailored jacket were compared by group. Chest, waist, and hip circumferences increased substantially as group size increased. The M-group was mostly satisfied with all body-site views. The S-group was especially dissatisfied with height, back width, waist circumference, and upper-arm circumference. The L-group was especially dissatisfied with waist circumference and hip circumference. The majority of the participants preferred the jacket closely fitted to their body. More than half of the participants thought finding a jacket of suitable size was difficult. When purchasing ready-to-wear jackets, the S-group and the M-group considered shoulder width important, while the L-group considered chest circumference the most important area. When evaluating the fit of ready-to-wear jackets, the L-group evaluated chest circumference, back width, and waist circumference as poor fits. The M-group evaluated sleeve length and shoulder width as poor fits, and the S-group agreed with respect to sleeve length. Body-satisfaction levels and matching jacket-satisfaction levels differed by body-size group, as did areas that need improvement. The conclusion is that size-group analysis using 3D body scanning can be utilized effectively for jacket-fit analysis. The findings of the current study can be applied to improving jacket fit among young male consumers.
