식료품의 종류에 따라 광원의 색온도 및 분광 스펙트럼을 달리하여 비춰주면 음식이 더욱 맛있고 신선하게 보인다. 이는 상품의 특정 색을 강조함으로써 소비자들의 시선을 집중시키고 시각적 구매욕을 상승시켜 상품판매를 촉진 시킬 수 있다. 본 연구에서는 다양한 식료품 중 어류를 대상으로 최근 3년 이내에 개장한 백화점과 대형마트의 색온도 적용 현황을 조사하고, 어류가 신선하고 맛있게 보이며 소비자들의 구입 선호도를 높일 수 있는 색온도를 도출하였다. 어류를 비추는 조명의 색온도 적용 현황 조사 결과, 백화점과 대형마트는 약 4,000~4,500 K의 색온도를 사용하는 것으로 나타났다. 또한 실험 결과, 어류에 적합한 색온도는 현재 적용되고 있는 4,000~4,500 K의 색온도인 것으로 도출되었으며, 특히 4,500 K일 때 어류가 가장 신선하고 싱싱하게 보이며, 어류가 가진 표면색이 가장 선명하게 보이는 것으로 도출되었다.

This study examined human emotional responses to chromacity of LED lighting with a brightness of 100 lx. The nine hues used in the experiment were R, YR, Y, GY, G, BG, B, P, and RP, and the three chromas used were high, intermediate, and low. By combining these hues and chromas, a total of 27 lighting elements were created for which emotional evaluation and preference assessment were conducted. The results were as follows: in terms of relaxation, stabilization, and luxuriousness, the intermediate and low chromaa with R, YR, and Y were evaluated highly, with more effectiveness displayed for the lower chroma. In particular, Y with low chroma was shown to reduce negative feelings such as “nervousness, depression, anxiety, and stuffiness,” while increasing positive emotions, such as stability and comfort. For creating futuristic, cutting-edge, and mystical atmospheres, hues such as BG, B, P, and RP were highly evaluated, with higher chroma inducing more effective results. In order to create light and glamorous atmospheres, warm hues such as R, YR, Y, and RP in high chroma were adequate. In terms of the temperature of the lighting, the respondents reported that hues such as BG and B were cooler, and hues such as R, YR, Y, and RP were warmer. Negative emotions such as “nervousness, depression, anxiety, and stuffiness” were highly evaluated for R, B, and RP that were in high chroma. Lastly, examination of the preference for lighting colors showed that the respondents liked all colors of lower chroma, especially color Y in low chroma. In addition, BG was found to be preferred across the border regardless of its chroma level.

동물상징 성격유형검사(ASPT)와 MBTI 간 선호지표에 따른 상관 연구
박금순 ( Geumsun Park ),최광현 ( Kwanghyun Choi ) 한국심리유형학회 2021 심리유형과 인간발달 Vol.22 No.2
본 연구는 동물상징 성격유형검사(ASPT)와 MBTI 두 검사 간 상관성 비교를 통해 ASPT의 타당도를 검증하고 상담 및 교육 현장에서 활용할 수 있는 기초자료를 제공하는 데 목적이 있다. 이를 위해 수도권 대학교에 재학 중인 대학생 356명을 대상으로 연구를 진행하였으며, 수집된 자료는 SPSS 27.0을 이용하여 카이제곱 검증을 실시하였다. 연구결과는 첫째, 무리생활은 외향형과 단독생활은 내향형, 가축동물은 감정형과 야생동물은 사고형, 가축동물은 인식형과 야생동물은 판단형에서 유의미한 차이가 있었다. 둘째, 목표/성취 유형은 ISTJ, 이상/비현실 유형은 ENFP, 관찰/분석 유형은 ISTJ, 충성/협동 유형은 ESTJ, 경계/방어 유형은 ENFP, 수용/화목 유형은 ISTP와 상관성이 가장 높게 나타났다. 이러한 연구결과는 ASPT의 타당도를 높였다는 것과 대학생들의 성격특성을 다각도에서 이해하고, 나아가 상담 및 교육 현장에서 효율적으로 활용할 수 있는 기초자료를 제공했다는 점에서 의의가 있으며, 본 연구의 한계점 및 추후 연구방향이 논의에 기술되었다. This study aims to verify the validity of ASPT and provide the baseline data that can be utilized in the fields of counseling and education, through a correlation analysis between two tests, Animal Symbol Personality Type (ASPT) and MBTI. For this purpose, this study was conducted with 356 college students enrolling in universities in the capital area, and with the collected data, a chi-square test was conducted, using SPSS 27.0. The results of the study are as follows: First, there were significant differences between animals living in groups and the extroverted type, between solitary animals and the introversion type, between livestock and the feeling type, between wild animals and the thinking type, between livestock and the perceiving type, and between wild animals and the judging type. Second, the goal/achievement type had the highest correlation with ISTJ; the ideal/unreal type, with ENFP; the observation/analysis type, with ISTJ; the loyalty/cooperation type, with ESTJ; the alert/defense type, with ENFP; and the acceptance/harmony type, with ISTP. The results of this study were significant in that they increased the validity of ASPT, understood the personality characteristics of college students from various angles, and further provided the baseline data that could efficiently be utilized in the fields of counseling and education. The limitations of this study and the subsequent research directions were stated in the discussion section.

The objective of this study is to deduct the range of illuminance and color temperature which is psychologically comfortable and stable, and can secure visibility. The presented lighting variables consist of 4 sorts of color temperatures of 3,000 K,4,000 K, 5,000 K, and 6,000 K, and 7 sorts of illuminance of 4 lx, 10 lx, 20 lx, 40 lx, 100 lx, 200 lx, and 400 lx. After getting the participants in the experiment to adapt themselves to the presented lighting environment for one minute, this study conducted an assessment of the evaluation vocabulary of ‘Comfortable-Stabilized’ , ‘ Uneasy-Tense’ and ‘of good Visibility’ by getting the participants to do so using the 5-phase Likert Scale. In addition, this study looked into separability and readability at a distance of 3 meters through ‘Telling the direction of the perforated part of Landolt ring’ and ‘Numeral Reading.’ The study results are as follows: 1) The participants were found to be uneasy and tense in illumination of less than 20 lx. On the contrary, the participants were found to be comfortable, stabilized, and more than normal even in visibility in illuminance of over 40 lx. This implies that at least more than 40 lx should be secured to secure psychological stability and visibility in the space requiring movements, or simple behavior. 2) As a result of doing readability evaluation through separability evaluation using Landolt ring, and numeral reading, the higher the space brightness, the more possible the cognition of even a tiny size form. In addition, the higher the color temperature, the easier it was to judge the form of an object by separation, or to read numerals.
