Cockpit 내에서도 다른 사회영역과 마찬가지로 "기장", "부기장"이라는 직함 및 직급에 의한 상하관계의 권력거리가 형성된다. 권력거리가 높은 우리나라 사회에서는 다른 사회영역과 마찬가지로 Cockpit 내에서도 권력거리가 높게 나타남은 분명한 사실이다. 그러므로 사회적 심리거리를 느끼는 부기장은 기장에게 운항안전에 관한 조언을 하는 데 있어서 상대적으로 위축되며, 또한 그러한 분위기도 형성되어 있지 않다. 따라서 승무원 간의 긴밀한 협력이 요구되는 Cockpit 환경에서 상호 간의 적극적인 Communication이 이루어져야 하지만 이러한 사회적 분위기 때문에 조언이 위축되고 크고 작은 운항안전 event, 심지어는 대형 사고로 이어질 수 있는 위험성을 내포하고 있다. 따라서 한국식 사고와 문화적 의식을 지니고 있는 조종사들은 문화적 마찰을 겪을 수 있다. 이러한 그들의 문화가 잘 스며든 효율적이고 안전한 운항을 위해서는 간단히 말해 그들의 문화와 맞추는 노력이 필요하다. 즉, 권력거리가 낮추는 연습이 필요 하다. 따라서 교육훈련도 거기에 맞추는 권력거리를 낮은 방식의 교육훈련이 효과적일 수 있다. 권력거리가 낮은 문화권의 교육의 중심은 교관과 학생간의 낮은 권력거리가 특징이다. 이를 바탕으로 교육훈련의 중심을 학생중심으로 맞추어 학생의 적극적인 참여를 이끌며, 교육자인 교관은 "Facilitator"로서의 역할을 수행할 필요성이 있다. 결과적으로는 학생과 교관과의 낮은 권력거리를 체험, 연습하게 되며, 실제 라인에서도 이러한 관계가 기장 부기장으로 이어지는 상하관계에 있어서도 주도적으로 참여, 조언할 수 있는 밑바탕을 제공해주어야 한다.

Mobile giving platform is a new type of giving platform which offers donation service through mobile application. Mobile giving platform has developed differently from offline giving platform in the way that induces continuous donation. The purpose of this study is to investigate why mobile giving platform has adopted different strategy, and how it leads to continuous contribution. We conducted a case study with two successful mobile giving platforms; Bigwalk and Tree Planet. The analysis of the strategy is based on the construal level theory which explains the relationship between psychological distance and construal level. The result shows that the users' psychological distance toward giving platform has decreased with the environmental change, offline to mobile. Consequently the mobile giving platform offers services which form low level of construal for encouraging continuous participation. This finding suggests the importance of offering suitable construal level in services, and design guideline for mobile giving platforms.

In this study, we investigate which alternatives to choose when giving a gift, according to the giver's relationship with the receiver. In particular, we study which alternatives are preferred when the prices are approximately the same: products with high-brand status but low-model ranking or products with low-brand status but high-model ranking. Leclerc, Hsee, and Nunes(2005) conceptualized the relative preference between a low-ranking model of a high-status brand and a high racking model of a low-status brand. The category effect is the preference for lower-ranking models of high-status brands. Meanwhile, the ranking effect refers to the preference for higher-ranking models of low-ranking brands. Based on construal level theory, the current study suggests that the category and ranking effects vary depending on the giver's relationship (vertical vs. horizontal) and intimacy (distant vs. close) with the person who will receive the gift. We manipulate the relationship and intimacy of the subject receiving the gift and verify the interaction effect. Results reveal that the giver exhibited a category effect in vertical relationships in which the psychological distance was far from the relationship. However, the ranking effect was found in horizontal relationships in which the psychological distance was close. Lastly, the gift selection significantly depends on the level. Overall, this study showed that when choosing a gift, the selection of a low-ranking model of a product from a high-tier brand or a high-ranking model from a low-tier brand might vary depending on the type of relationship and the level of intimacy. In addition, our findings provided managerial implications in targeting and marketing communication strategies based on product status.

With the consumption of smart phone content increasing rapidly, the short clip market in China is rapidly growing. TikTok, a short clip platform, has achieved great business success. However, there is not much research done on TikTok platform from the customers' perspective. To this end, this study aimed to verify the relationship between the social network characteristics on the TikTok platform, attachment toward the TikTok platform, user participation, social identity, psychological distance and reuse intention through an empirical investigation. In August 2021, a survey was conducted on consumers on the subject of TikTok platform in China. The results of the study are as follows. First, the social network characteristics significantly affected the user participation and the attachment. Second, both the attachment and the user participation had a significant impact on reuse intention. Third, user participation had a significant impact on attachment. Fourth, social identity played a significant moderating role in the relationship between social network characteristics and user participation. Fifth, Psychological distance played a significant moderating role in the relationship between social network characteristics and attachment. The results of this study are expected to provide theoretical and practical implications for research on TikTok platform.

Outlier(이상치) 분석을 통한 등부표 선회안전반경 정보 제공에 관한 연구는 AIS 또는 RTU가 설치된 등부표에 대한 이탈 위험 인지, 항해안전 사고 예방 등 안전대책을 강화하기 위한 연구이다. 등부표는 조류, 바람 등 외력에 의해 이출거리가 발생하여 일정한 패턴으로 선회반경이 형성되나 외력으로 인하여 정상범위에서 벗어나 유실, 위치이동 등이 발생할 수 있고 이는 선박추돌 등 항해안전 사고로도 이어질 수 있다. 이러한 등부표 사고는 물적 피해비용과 이용자의 안전운항에 대한 심리적 부담감 또는 위험감수 등의 추가적인 행정소요 비용이 발생할 수 있다. Outlier(이상치)란 외력 등으로 인해 최대 이출거리 이내 정상범위에서 벗어나거나 존재할 수 없는 극단적인 위치 값으로써 21년도 등부표 위치 데이터를 일정 단위 방위별로 분석해 본 결과 Outlier(이상치)가 식별되었다. 따라서 등부표의 안전한 위치 상태를 시스템적으로 모니터링 하기 위해 Outlier(이상치) 분석을 통한 등부표 선회안전반경 정보 제공에 관한 연구를 하였다.

Although CSV means pursuing social and economic values at the same time, research on consumer benefits recognized by consumers, the subject of economic value, is insufficient. The purpose of this study is to investigate the effect of CSV activities of financial companies on purchase intention through consumer benefits and psychological distance for consumers. 265 copies of survey data were collected, and the research hypothesis was verified using SPSS 25.0 and Smart PLS 3.0. As a result of the analysis, first, fairness and authenticity had a positive (+) effect on both social and personal benefits. Second, it was found that the social and personal benefits subjectively perceived by consumers had a positive (+) effect on both purchase intention. Third, it was found that the social benefits perceived by consumers through CSV activities of financial companies had a positive (+) effect on purchase intention through psychological distance, but the mediating effect of personal benefits was not significant. Based on these research results, practical proposals were made to increase the efficiency of CSV activities by grasping the effect of consumers and purchase intentions on CSV activities of financial companies, and conclusions, implications, and future research directions were presented.

This article proposes a new pedestrian avoidance algorithm for social robots that coexist and communicate with humans and do not induce stress caused by invasion of psychological safety distance(Social Distance). To redefine the pedestrian model, pedestrians are clustered according to the pedestrian's gait characteristics(straightness, speed) and a social distance is defined for each pedestrian cluster. After modeling pedestrians(obstacles) with the social distances, integrated navigation algorithm is completed by applying the newly defined pedestrian model to commercial obstacle avoidance and path planning algorithms. To show the effectiveness of the proposed algorithm, two commercial obstacle avoidance & path planning algorithms(the Dynamic Window Approach (DWA) algorithm and the Timed Elastic Bands (TEB) algorithm) are used. Four cases were experimented in applying and non-applying the new pedestrian model, respectively. Simulation results show that the proposed algorithm can significantly reduce the stress index of pedestrians without loss of traveling time.

This qualitative study aimed to develop a structural framework that explains the process of psychological adaptation and sequential changes being perceived by Korean people under the COVID-19 Pandemic past year. Setting a tentative analysis frame induced from antecedent literatures about psychological phenomena during the COVID-19 pandemic, the qualitative data were collected from 6 Korean adults by semi structured individual interviews. For the data, content analysis applied from the grounded theory were performed. As a result, the initial framework was extended and revised to describe the psychological phenomena under the pandemic. This paradigm structure includes the process of 'causal factors ⇒ psychological main phenomena ⇒ sequential results' being intervened by personal contextual situations and psychological characteristics, as moderators. The category of causal factors were the COVID-19 pandemic, relevant critical incidents, and social distancing policy. The main phenomena reflected either positive, negative, or complicated experiences. The sequential psychological results included transformation of cognitive system or behavior patterns. Various variables such as psychological sense of community and social responsibility, psychological capability for leisure, and positive psychological capital were found out as moderating factors. In discussion and conclusion, theoretical/practical implications of the results and direction to study in the future were suggested.
