오프라인의 실제적 자아와 SNS에서의 자아 간의 자아불일치에 영향을 미치는 선행요인과 결과요인

유은아(Yu, Eunah),최지은(Choi, Jieun) 한국소비문화학회 2015 소비문화연구 Vol.18 No.3

SNS 이용자들은 SNS를 통하여 자아정체성을 표출하고자 하는 이용 동기가 크기 때문에, 자아이미지는 SNS 내 정보의 생산 및 게시, 유통에 있어 중요한 기준점이 될 수 있다. 이러한 과정에서 SNS 이용자들은 다른 사람의 시선과 평가에 주의를 기울이며, 자신의 이미지를 SNS 내에서 긍정적으로 표현하고자 한다. 이에 SNS 내에서 보이는 자신의 이미지는 실제 오프라인에서의 이미지와 간극이 발생할 수 있다. 본 연구는 이러한 오프라인에서의 실제 자아와 SNS 내에서 보이는 자아 간의 불일치에 영향을 미치는 요인들에 대하여 규명하였다. 이를 위하여 먼저, 선행연구를 근거로 자아불일치에 영향을 미치는 소비자 개인특성 변인으로 사회비교경향성과 공적자기의식을 살펴보았으며, 결과요인으로 SNS 내 사회자본형성과 삶의 만족을 제안하였다. 연구결과 SNS 이용자의 개인특성 변인인 사회비교경향성은 이용자의 자아불일치에 유의한 영향을 미치는 것으로 나타났으나, 또 다른 개인특성 변인인 공적 자기의식은 자아불일치에 유의한 영향을 미치지 않는 것으로 나타났다. 자아불일치의 결과요인에 대한 검증결과, 자아불일치는 결속적 사회자본에 유의한 관계를 나타냈으나 연결적 사회자본에는 유의한 영향을 미치지 않았다. 또한, 결속적 사회자본은 삶의 만족에 유의한 영향을 미쳤으나, 연결적 사회자본은 삶의 만족에 유의한 영향을 미치지 않는 것으로 나타났다. 이와 같은 연구결과는 SNS에서의 자아표현과 관련된 소비자 심리와 행동에 대한 이해를 제공하고, 향후 SNS 내 소비자 행동과 관련된 연구의 범위를 확장하였다는 데에 의의가 있다. SNS users generally desire to express their identity on SNS, and, recently, SNS is increasingly being used as a self-presentation tool. Regarding self-projection, SNS users tend to pay attention to other users' opinions or evaluations, and thus are likely to create a positive self-image on SNS. When they seek to deliver only a positive SNS self-image, there can be a discrepancy between actual-self and self. Thus, this research examines the antecedents and consequences influencing the discrepancy between actual-self and self on SNS. This study commences with the hypothesis that social comparison orientation and public self-consciousness are antecedents of self-discrepancy. It further posits that users exhibiting a high tendency toward social comparison orientation and public self-consciousness tend to exaggerate their self-image, thereby creating self-discrepancy between actual-self and self on SNS. These two hypotheses leads to a third, self-discrepancy that reduces bonding social capital and bridging social capital, which in turn results in lower life satisfaction. To verify these hypotheses, the researchers conducted a survey and, adopting a structural equation model, analyzed the data. Results revealed that social comparison orientation was positively related to self-discrepancy but did not reveal even a marginal relationship between public self-consciousness and self-discrepancy. Further results disclosed that self-discrepancy had a negative impact on bonding social capital, while self-discrepancy had no impact on bridging social capital. Regarding life satisfaction, only lower bonding social capital lowered life satisfaction, as no relationship between bridging social capital and life satisfaction was identified. Based on this results, theoretical and practical implications are discussed.

유은아(Yu, Eunah),최지은(Choi, Jieun) 한국산업경영학회 2021 경영연구 Vol.36 No.4

장기화되는 코로나 펜데믹 상황에서 도시에 거주하는 도시 거주민의 불안은 가중되고 있다. 본 연구는이러한 도시 거주민의 불안과 연결감이 도시 브랜드 만족에 미치는 영향을 규명하고자 하였다. 연구 결과에따르면 사회적 연결감과 자아-도시 연결감은 각각 도시 브랜드 만족에 긍정적인 영향을 미쳤지만 도시 거주불안은 도시 브랜드 만족에 부정적인 영향을 미쳤다. 본 연구는 이러한 각 변인의 주 효과 외 변수 간의상호작용 효과를 검증하였는데 사회적 연결감과 자아-도시 연결감의 상호작용 효과가 유의하게 보고되었다. 구체적으로 사회적 연결감이 낮을수록 자아-도시 연결감이 도시 브랜드 만족에 더 큰 영향을 미치는 것으로나타났다. 마지막으로 사회적 연결감, 자아-도시 연결감과 도시 거주 불안 간의 삼원상호작용 효과가 나타났다. 즉, 도시 거주 불안이 낮은 경우 사회적 연결감과 자아-도시 연결감 간의 상호작용 효과가 유의하게나타나지만, 거주 불안이 높은 경우 이러한 상호작용 효과는 나타나지 않았다. 본 연구의 결과는 도시 거주민을 대상으로 도시 브랜드 연구를 진행하였다는 데에 나름의 의미를 지니며, 도시 브랜드 연구에 심리적 요인을 결합하여 이론적 확장을 하였다는 데에 이론적 의의가 있다. 또한, 불안이 가중되는 시대에 도시 거주민의도시 브랜드 만족 제고와 관련된 실무적 시사점을 제공해준다. During the prolonged coronavirus pandemic, the anxiety of city dwellers has been increasing. The purpose of this study was to investigate the effects of urban dwelling anxiety, social connectedness and self-city connectedness on city brand satisfaction. We surveyed 307 men and women in their 20s and 30s living in either Seoul or Busan, and measured urban dwelling anxiety, social connectedness, self-city connectedness and city brand satisfaction. According to the results of the study, social connectedness and self-city connectedness had a positive effect on city brand satisfaction, but urban dwelling anxiety had a negative effect on city brand satisfaction. In addition, the three-way interaction effect between social connectedness, self-city connectedness, and urban dwelling anxiety on city brand satisfaction was investigated. Specifically, when urban dwelling anxiety was low, the interaction effect between social connectedness and self-city connectedness was significant, but when urban dwelling anxiety was high, this interaction effect did not appear. The results of this study contribute to expanded research on city branding by combining psychological factors with city branding. In addition, the study provides practical implications on how to enhance city brand satisfaction among urban residents in the COVID-19 era.

To use a language is not just a simple activity of reading or writing letters. Rather it is to grasp the meaning of the letters and to express it in user’s own language. In author’s own experience. most students who have reading difficulties do not use a language in the strict sense. It is not easy to improve their language ability. although teachers try to help them for their language ability and they have an eager desire to improve their language ability. This study has been motivated by a question of how the students with reading difficulty can improve their reading competence Man symbolizes informations visually and linguistically. When we hear a story. it is easy to understand and memorize the meaning of the story if we make concrete visual images in our mind. The graphic organizer instruction can be supposed to help the students who have reading difficulties to relate one of their‘ learning tasks to the other in meaningful way and to develop their cognitive structure. The purpose of this study is to improve the reading competence of students who have reading difficulties by graphic organizers. For this purpose , in chapter 2. I examine theories on the relationship between text structure and graphic organizer , the effect of graphic organizer on reading competence. characteristics of underachievement in reading and proper ways to use graphic organizers in teaching In chapter 3, I devise research method and procedures of this study project. To verify the research hypothesis ‘graphic organizers will improve reading competence of students who have reading difficulty. I design a special program for 34th grade children who have reading difficulties. In chapter 4. I explain about teaching contents in each stage of the program for improving underachievers’reading ability which is devised by the researcher using graphic organizers. I also illustrate a teaching model for each instructional unit according to researcher's idea of graphic organizer instruction. I present a practical example of instruction according to the program and introduce how the teaching method has been changed by this program‘ In chapter 5, I describe and analyse how the underachievers' reading competence has been improved through the program which consists of baseline test. 15 times interventions and maintenance stage. The students' reading competence has been gradually improved from the first stage of graphic organizer instruction. when the graphic organizer was divided into 4 stages and intervened into teaching, and the improvement has been stably kept up during the maintenance period. Therefore. it can be conclude that the graphic organizer instruction is effective to improve the reading competence of students with reading difficulties The significance of this study is that the reading competence of children with reading difficulties has been improved by graphic organizer instruction which helps children not only to acquire the form and the making rule of graphic organizers , but also to reconstruct the content of the text in their own language and thinking. This study provide an opportunity for‘teachers. to predict and to treat children’s responses In teaching and learning situation. based on children' s responses shown in this study report. The result of this study cannot be generalized. because this study has been conducted with only on 34th grade children who have reading difficulty focused only on explanatory texts. Therefore. for further studies. it is recommended to extend numbers of children and types of text and to develop a more effective method for improving reading competence by a more proper research design. It is also recommended to research into characteristics of students with reading difficulties based on children's responses which has been shown throughout the whole stages of graphic organizer instruction.

Grinding System is very difficult to examine closely wear phenomenon or dynamic characterastic, because it is very complex and different from a general cutting system. Considering automatization and precision, it is very important to examine closely grinding system. In this study, grinding wheel surface is acquired by using computer vision system in order to explain wear and loading phenomenon. We investigate the relationship between wear and Fourier spectrum of acquired image, and observe the entropy variation in the process of manufacturing.

Mordern industrial society pursues unmanned system and automation of manufacturing process. Abreast with this tendensy, production of goods which requires advanced accuracy is increasing as well. According to this, the work sensing time of dressing by monitoring and diagnosing the condition of grinding, which is th representative way in accurate manufacturing, is an important work to prevent serious damages which affect grinding process or products by wearing grinding wheel. Computer vision system was composed, so that grinding wheel surface was acquired by CCD camera and the change of cutting edge ratio was measured. Then we used automatic thresholding technique from histogram as a way of dividing grinding cutting edge from grinding surface. As a result, we are trying to approach unmanned system and automation by deciding more accurate time of dressing and by visualizing behavior of grinding wheel by making use of computer vision.
