This study attempted to investigate the influence of self-image congruity on brand attitude in beauty salons. In this study, a questionnaire survey was conducted among customers of hair salons in the regions of Jeju, Seoul, and Gyeonggi-do. Among a total of 700 questionnaires distributed, 630 copies were collected. Excluding 10 poorly answered ones, 620 copies were used for final analysis. The collected data were analyzed, using SPSS 22.0., and the results found the followings: First, in terms of the influence of self-image congruity, ‘Social self-image’ was the largest, followed by ‘Ideal self-image’ and ‘Actual self-image’ with statistical significance. In terms of brand attitude, ‘Affective attitude’ was the highest, followed by ‘Intimate attitude’ with statistical significance. Second, in the influence of self-image congruity on brand attitude, as ‘Ideal self-image’, ‘Social self-image’ and ‘Actual self-image’ improved, both ‘Affective attitude’ and ‘Intimate attitude’ were higher. This study is meaningful in that it suggested a brand direction for beauty salons. Consumers’ self-image congruity is a critical element in an individual brand strategy. They tend to choose a favorable, positive and familiar brand as a means of expressing their emotions and desire. Therefore, it is required to develop marketing communication strategies which can induce more active brand attitude based on such consumer needs.

헤어살롱의 브랜드이미지가 자아이미지 일치성과 브랜드 충성도에 미치는 영향

장은수,정건아,박은준 한국미용학회 2023 한국미용학회지 Vol.29 No.4

This study aimed to investigate the influence of the congruence between brand image and self-image on brand loyalty within the context of hair salons. A total of 620 online surveys were distributed to hair salon customers in Seoul, Gyeonggi, and Jeju regions using Naver Form, with all 620 surveys successfully collected. The research findings revealed the following key results. Firstly, among the sub-factors of self-image congruence, both ideal self-image and actual self-image were found to significantly impact the brand image, with symbolic image, experiential image, and functional image being the order of significance. Additionally, the sub-factor of social self-image was found to significantly influence the brand image, following the order of symbolic image and experiential image. Secondly, among the sub-factors of brand loyalty, attitudinal loyalty demonstrated a significant influence in the following order: functional image, experiential image, and symbolic image of the brand image. On the other hand, behavioral loyalty showed a significant impact in the order of functional image and symbolic image of the brand image. Thirdly, both attitudinal and behavioral loyalty, as sub-factors of brand loyalty, were found to be significantly influence the sub-factors of self-image congruence, with the order of importance being ideal self-image, social self-image, and actual self-image. This study emphasizes the importance for hair salon brands to focus on enhancing their brand image and strive to align consumer self-image with the brand image. By recognizing and adapting to this congruence, hair salons can effectively increase brand loyalty.

목 적 : 외부 압박을 통해 전립선암 환자의 복강 내 압력을 안정화시켜 움직임을 감소하여 치료 간(interfraction)과 치료 중(intrafraction)에 변화를 측정하여 평가하고자 시행하였다. 대상 및 방법 : 10명의 전립선환자들은 전체 치료과정동안 MVCT 스캔을 통해 치료 전과 후에 걸쳐 환자 당 60개의 영상을 획득하였고 획득한 좌우방향(X), 상하방향(Y), 전후방향(Z), 회전방향(Roll)에 대한 Shift 값들을 이용하여 복부 압박 시 치료 간 치료준비 변화와 치료 중 표적 움직임의 상호 연관성을 분석하였다. 결 과 : 치료 간의 움직임 변화는 평균 좌우방향(X)에서 $0.65{\pm}2.32mm$, 상하방향(Y)에서 $1.41{\pm}4.83mm$, 전후방향(Z)에서 $0.73{\pm}0.52mm$, 회전방향(Roll)에서 $0.96{\pm}0.21^{\circ}$로 나타났다. 치료 중 움직임 변화는 평균 좌우방향(X)에서 $0.15{\pm}0.44mm$, 상하방향(Y)에서 $0.13{\pm}0.44mm$, 전후방향(Z)에서 $0.24{\pm}0.64mm$, 회전방향(Roll)에서 $0.1{\pm}0.9^{\circ}$로 나타났다. 결 론 : 전처치과정과 외부에서 복부압박을 통한 전복부의 움직임을 제한한다면 치료동안에 내부 장기와 환자의 움직임을 감소시켜 보다 적은 여유(margin)로 계획용 표적체적(PTV)을 생성할 수 있어서 정상조직의 부작용 증가 없이 더욱 이상적인 선량 체적을 얻을 수 있을 것으로 사료된다. Purpose : To evaluate the changes of the motion of abdominal cavity between interfraction and intrafraction by using abdominal compression for reducing abdominal motion. Materials and Methods : 60 MVCT images were obtained before and after tomotherapy from 10 prostate cancer patients over the whole radiotherapy period. Shift values ( X -lateral Y -longitudinal Z -vertical and Roll ) were measured and from it, the correlation of between interfraction set up change and intrafraction target motion was analyzed when applying abdominal compression. Results : The motion changes of interfraction were X-average $0.65{\pm}2.32mm$, Y-average $1.41{\pm}4.83mm$, Z-average $0.73{\pm}0.52mm$ and Roll-average $0.96{\pm}0.21mm$. The motion changes of intrafraction were X-average $0.15{\pm}0.44mm$, Y-average $0.13{\pm}0.44mm$, Z-average $0.24{\pm}0.64mm$ and Roll-average $0.1{\pm}0.9mm$. The average PTV maximum dose difference was minimum for 10% phase and maximum for 70% phase. The average Spain cord maximum dose difference was minimum for 0% phase and maximum for 50% phase. The average difference of $V_{20}$, $V_{10}$, $V_5$ of Lung show bo certain trend. Conclusion : Abdominal compression can minimize the motion of internal organs and patients. So it is considered to be able to get more ideal dose volume without damage of normal structures from generating margin in small in producing PTV.

목 적 : 간암 치료 시 호흡으로 인한 움직임을 최소화하기 위해 환자 체위 변화에서 종양의 움직임과 용적 변화를 분석하고자 하였다. 대상 및 방법 : 간 세포암종(Hepatocellular Carcinoma) 환자 14명의 환자를 대상으로 시행하였다. 바로 누운 자세(Supine position)와 엎드린 자세(Prone position)에서 2가지 방법으로 환자 고정기구를 제작하고 영상을 획득하여 간 종양의 움직임과 용적 그리고 선량을 분석하였다. 결 과 : 바로 누운 자세(Supine position)와 엎드린 자세(Prone position) 에서 표적의 왼쪽-오른쪽(LR, Left-right) 움직임은 평균 $2.76{\pm}1.25mm$, $2.21{\pm}0.93mm$이고, 앞-뒤(AP, Anterior-posterior)와 상하(SI. Superior-inferior) 방향의 움직임은 각각 $4.02{\pm}1.63mm$, $11.56{\pm}3.08mm$, $3.36{\pm}1.17mm$, $7.45{\pm}1.96mm$이었다. 이를 이용한 엎드린 자세(Prone position)에서 치료 용적(Treatment volume)은 감소하였고, 이에 따라 정상간 용적은 증가 하였다. 결 론 : 호흡에 의한 간의 움직임을 최소화함으로써 치료 용적(Treatment volume)의 경계여유를 감소시킬 수 있었다. 즉 환자 자세 변화 특히 엎드린(Prone) 자세는 간의 움직임을 감소 시켜주고 정상 간의 용적을 증가 시킬 수 있을 것으로 사료된다. Purpose : To analyze tumor's movement and volume change from changing position in order to minimize movement caused by breathing. Materials and Methods : We conducted survey of 14 patients with HCC(Hepatocellular carcinoma). Patient immobilization device was made in two ways(Supine position, prone position) and from image acquisition, tumor's movement, volume and dose are analyzed. Results : The mean movement of target(LR, Left-right) in supine position and prone position was $2.76{\pm}1.25mm$, $2.21{\pm}0.93mm$. AP(Anterior-posterior) and SI(Superior-inferior) was $4.02{\pm}1.63mm$, $11.56{\pm}3.08mm$, $3.36{\pm}1.17mm$, $7.45{\pm}1.96mm$. Treatment volume was decreased and normal liver volume was increased in prone position. Conclusion : We could reduce the margin of the treatment volume by minimizing the movement of liver caused by breathing. Especially in prone position, it is considered to be able to decrease the movement of the liver and increase normal liver volume.

목 적 : 다양한 치료 부위에 따라 MVCT(Megavoltage computed tomography)를 이용하여 치료 중(Intrafraction), 치료 간(Interfraction)의 장기 위치 변화를 측정하여 평가하고자 한다. 대상 및 방법 : 본 연구에서 두 경부(Head & neck), 흉부(Thorax), 간(Liver), 전립선(Prostate) 종양을 가진 48명 환자들은 전체 치료 과정동안 다양한 MVCT scan을 시행하였다. 평균 환자 당 60개의 MVCT 영상을 획득하여 분석하였다. 결 과 : 치료 간(Interfraction)오차는 흉부와 복부 그리고 골반이 종 방향(Longitudinal, Y)에서 3 mm 이상의 차이를 보였다. 치료 중(Intrafraction) 변화를 알아보기 위해 치료가 끝난 후에 MVCT를 찍어 확인한 후 치료 중(Intrafraction) 움직임 차이는 종 방향에서 2 mm 내외로 나타났다. 또한 치료 전과 후의 움직임의 변화로 인해 치료 간 그리고 치료 중의 차이를 확인하였다. 결 론 : 본 연구에서도 두 경부(Head & neck), 흉부(Thorax), 간(Liver), 전립선암(Prostate cancer) 환자들의 치료 간(Interfraction) 변화와 치료 중(Intrafraction)변화를 통해 적절한 고정 기구와 표적 여백의 윤곽을 완성하는데 도움이 될 거라 사료된다. Purpose : Depending on a variety of therapeutic areas using MVCT(Megavoltage computed tomography) intra-and interfraction is to evaluate changes in patient position. Materials and Methods : In this study, head and neck, thorax, liver, and prostate tumor patients, 48 people with a full course of treatment for patients with various MVCT scan was performed. Average 60 per patient MVCT images were acquired and analyzed. Results : Interfraction error thorax and abdomen, and pelvis in the longitudinal difference was more than 3 mm. Intrafraction to see a change after the end of treatment MVCT taken, and the results confirmed Intrafraction 2 mm in motion around the longitudinal difference. In addition, due to changes in the movement before and after treatment, Inter-and Intrafraction difference was found. Conclusion : In the present study, the Head and Neck, Thorax, liver, prostate cancer in patients with inter-and intrafraction changes and target the appropriate fixtures to complete the outline of the margin would be helpful is considered.
