Objective : This study was done to examine the cytotoxicity of styrax benzoin (SB) on human oral epithelioid carcinoma cell line (KI3). Methods : The cytotoxic effect of SB was measured by MTT assay or XTT assay. The microscopic study was performed to observe the mophorlogical changes of KI3 cells. Results : The cytotoxic effect of SB on KI3 cells showed a significant increase at 50 uM or 100 uM SB by MTT assay or XTT assay compared with control after cells were treated with various concentrations of SB for 48 hours. MTT_(50) and XTTg were 419.9 uM and 375.5 uM, respectively. In microscopic study, KB cells exposed to SB showed both the decreased cell number and the morphological changes. Conclusion : From these results, SB has a midcytotoxicity by the showing the decrease of cell number and the morphological changes in KJ3 by MTT and XTT assays.

리튬 이온 배터리 (LIB) 용 상용 전극은 현재 활성물질을 바인더와 전도체와 함께 유기 용매인 N-methyl-2-pyrrolidone (NMP)에서 혼합하여 도포하는 방법으로 제조되고 있다. 이때 사용되는 NMP는 유기용매로서 독성이 있으며 가격 또한 저렴하지 않으므로, 물에서 전극물질을 프로세싱 한다면 상당한 비용절감의 효과가 있다. 본 연구에서는 그래핀 옥사이드를 사용하여 LiFePO4를 물에서 분산시키고 스프레이 방법을 사용하여 NMP를 사용하지 않고 LiFePO4/GO 를 코팅한 후 열처리를 통해서 LiFePO4/rGO 를 제조하였다. LiFePO4/rGO 는 LIB의 양극으로 사용되었을 때 높은 전류에서 LiFePO4보다 향상된 성능을 나타내었다.

Objective : The aim of this study was to evaluate cytotoxic effect of benzoic acid on normal human skin fibroblast cell line , Detroit 551. Methods : The cytotoxicity was determined by colorimetric assays such as MTT assay or XTT assay. The microscopy was carried out to observe Detroit 551 cell line. Cells were incubated with various concentrations of benzoic acid in CQ incubator controlled with 37 c for 48 hours. Results : The cytotoxic effect of benzoic acid on Detroit 551 did not show a positive significance at 50 uM and 100 uM benzoic acid by MTT assay or X T T assay compared with control. MTTB and XTTg were 900.6 uM and 974.6 uM, respectively. In microscopic study, Detroit 551 treated with benzoic acid showed a slightly decreased cell number, while the morphological changes of cell was not showed. Conclusion : Above the results, the cytotoxicity of benzoic acid was midtoxicity on normal human skin fibroblasts cell line. Detrit 551

상담자의 예술인 상담 경험에 대한 합의적 질적 연구

전주원,김은하 한국상담심리학회 2023 한국심리학회지 상담 및 심리치료 Vol.35 No.2

This study used the Consensual Qualitative Research method to explore the experiences of counselors who worked with artists. In-depth interviews were conducted with eight professional counselors who had worked with at least five artists. Counselors’ perceived characteristics of artist clients fell into five domains: environmental characteristics, personal characteristics, psychological difficulties, strengths in counseling, and vulnerability in counseling. Counselors’ experiences working with artists were categorized into three domains: difficulties in counseling artists, positive experiences in counseling artists, and important aspects in counseling artists. The findings of this study are expected to provide practical information to counselors working with artists, and further serve as a foundation for developing counselor training programs for counseling artists. 본 연구는 예술인(예술 활동을 직업으로 삼고 경제활동을 하는 자) 내담자를 상담하면서 상담자가 어떤 경험을 하는지 살펴보기 위해 수행되었다. 이를 위해, 5사례 이상의 예술인 상담 경험이 있는 상담자 8명을 대상으로 반구조화된 심층 면담을 실시하고, 합의적 질적 방법을 통해 자료를 분석하였다. 그 결과, 상담자가 지각한 예술인 내담자의 특성에 대해서는 ‘예술인 내담자의 환경적 특성’, ‘예술인 내담자의 내적 특성’, ‘예술인이 호소하는 심리적 어려움’, ‘상담에서 예술인 내담자의 강점’, ‘상담에서 예술인 내담자의 취약성’ 등 5개의 영역이 도출되었다. 또한 예술인 상담에서 상담자의 경험에 대해서는 ‘예술인 상담에서 상담자가 느끼는 어려움’, ‘예술인 상담에서 상담자의 긍정적 경험’, ‘예술인 상담에서 중요하다고 판단한 점’ 등 3개의 영역이 확인되었다. 본 연구의 결과는 향후 예술인 내담자를 상담하게 될 상담자들에게 실질적인 정보를 제공하고, 더 나아가 예술인 상담에 대한 상담자 교육 프로그램을 개발하는데 기초자료로 활용될 수 있을 것으로 기대된다.

공간마케팅 측면에서 바라본 커피 전문점의 공간 디자인 연구 -스타벅스를 중심으로-

(Background and Purpose) We are under the great influence of space where we establish personal personality, seeking our subjectivity or realizing our ego. Also, consumer patterns become more complex and diversified, and eventually become new forms. Companies are starting to add value to the keyword ‘space’ to attract modern consumers having patterns such as expression of identity, cultural consumption, storytelling, experiential space, and emotional consumption. Finally, the company chose a multidimensional space marketing strategy. After companies put values and culture in space, the space itself became the consumption product beyond the original meaning of space where goods are traded. In the end, the company has attracted a lot of loyal customers with increasing ties between business and consumers. The trend of space marketing also spread to coffee shops where identity and storytelling began to appear in the space. Therefore, this study studies the significant meaning and value of space by viewing the space of a coffee store with a space marketing perspective. Therefore, this paper aims to analyze the meaning of space of coffee shops by analyzing the outstanding space marketing cases of Starbucks coffee stops that have recently received attention in Korea and abroad. (Method) First, we researched space marketing and coffee shops. Second, from the perspective of space marketing, we analyzed coffee shops, then studied the consumption patterns of modern consumers and the value of space marketing of coffee shops and then identified the elements of space marketing of coffee shops. Based on the space marketing analyzed, we analyzed Starbucks' space design and created an analysis framework. Third, using the analysis framework, we selected and identified the best coffee shops among Starbucks branches, and then analyzed them with the view point of the space marketing and expression elements. (Result) The best cases in common showed that they focused on the value of space and implemented space marketing effectively. They were all Starbucks franchises, but they expressed culture and values suitable for each space, which created an environment where consumers consume the culture filled in the space rather than simply drinking coffee. (Conclusions) Starbucks is a coffee shop that paid attention to the cultural value of the space and showed efficient space marketing. Starbucks did not view space as media of consumption for consumption and trade of coffee. Rather, they viewed space as a key object of consumption by creating a space that contains the culture and values of Starbucks where consumers consume the brand and recognize the brand's identity, and emotional solidarity is formed through their interaction with each other. We expect our thesis to reintroduce the significant meaning and importance of space marketing and to be used as basic data for space marketing.
