Myself in Snapchat vs. Instagram: The interactive effect of users’ self-construal and their SNS uses related to the efficacy of an advertisement

김동후,Joseph Michael Czabovsky,Michele Lynn Meyer 한국광고학회 2022 광고학연구 Vol.33 No.4

This study investigates how using a specific SNS platform has impact on users’ self-construals. Also, this research examines the effect of the association between SNS platforms and users’ self-construals in improving the efficacy of advertising in SNSs. Based on self-construal theory and information processing model (affective vs. cognitive processing), it is assumed that users’ self-construals can be primed by their SNS use and the primed self-construals can have impact on their information processing in SNS contexts. Two laboratory experiments were conducted to test these assumptions. A total of 191 (Study 1 – 74 & Study 2 – 117) undergraduate students participated in this research. The findings from study 1 empirically supported that SNS platforms could prime users’ self-construals differently. The results from Study 2 not only provided compatible evidence that SNS platforms can change users’ self-construal but also demonstrated the interplay between the primed self-construal by SNS platforms and ad types (emotional appeal vs. cognitive appeal ad) in shaping individuals’ response toward the ad. Also, the mediating role of users’ self-construal on the interplay between SNS platforms and ad types.was confirmed. Since the current research tested two image-based SNS platforms with undergraduate students, future research may need to test different population with more various platforms to re-examine the findings from this study. The current research contributes to the field by expanding the self-construal concept in SNS research, as well as provides practical implications to improve the efficacy of SNS advertising campaigns.

The purpose of this study was to investigate the quality change of fresh-cut tumeric (Curcuma Longa Linne) according to packaging method during storage time. The fresh-cut tumeric were packaged in three different methods : degassing valve packaging (DVP), CO2 gas absorber packaging (CAP) and micro-perforated packaging (MPP). After the samples were packaged, they were stored for 15 days at 4 and 23oC respectively. The following parameters were observed to indicate the quality changes of the samples: weight loss, CIE L*a*b* colour difference, variation of gas composition inside the package, curcumin contents and changes in hardness of fresh-cut tumeric. DVP did not effectively release CO2 gas to the outside. MPP was suitable to release CO2 gas. However, MPP showed very fast browning and erosion, because a large amount of oxygen was introduced through the perforated hole on the film. CAP was most effective packaging method to inhibit browning, to prevent expansion of the packaging by CO2 gas and to minimize weight loss of freshcut tumeric.

Bonding Snapchat vs. Bridging Instagram? A Laboratory Study of the Association between Social Networking Sites and Social Capital

김동후,이소영,성윤희 한국정보사회학회 2020 정보사회와 미디어 Vol.21 No.1

This study builds upon existing research examining the relationship between social networking sites (SNS) use and social capital by investigating what drives the underlying reciprocal interaction. While prior investigations of the SNS-social capital relationship employed self-report methods, this study employs a laboratory-based experiment. As strong exemplars of SNS, Snapchat and Instagram, specifically, were chosen for investigative focus. A total of 161 undergraduate students from a major southeastern university in the U.S. participated in this research in exchange for extra credits. Participants were provided questions about their usage patterns, such as time spent on SNS usage in general and intensity of the assigned SNS use (Snapchat or Instagram). Then, participants were asked to log into their Snapchat or Instagram accounts and spend twenty minutes using it as they normally would, such as posting snaps and liking and browsing pictures of others. Based on the average time spent per day on Instagram and Snapchat by U.S. users, the twenty-minute experimental condition was designed. After twenty minutes, their social capital was measured Results demonstrated that participants who used Snapchat were more highly associated with bonding social capital (strongly tied relationship) than those who used Instagram. However, using Instagram did not lead participants to be more concerned with bridging social capital (weakly tied relationship) than those using Snapchat. In addition, when an individual’s social capital was examined as it existed both prior to and after using SNSs, only bonding social capital in the Snapchat condition was significantly changed. After using Snapchat, individuals’ bonding social capital became stronger than it was pre-SNS engagement. However, when individuals used Instagram, no significant difference in bridging social capital was detected. Through the laboratory experiment, the current research can provide more valid and accurate data for understanding the relations between SNS use and users’ social capital. Since it is challenging for individuals to remember or precisely describe their SNS use, several researchers have expressed the need to adopt more ideal methods to directly measure data, such as a laboratory-based study. By avoiding the validation issues that exist with self-report measures, the current research contributes to the improvement in methodological approaches to SNS research. In addition, the study found that bonding social capital can be influenced by a certain type of SNS platform (e.g., Snapchat), whereas bridging social capital was not. Hence, individuals can obtain their bridging social capital without limitation with regard to SNS type, but to obtain bonding social capital, a SNS platform that allows one to interact and develop strong social ties can be more effective than other SNS platforms. At the same time, given that social capital allows a person to make use of resources from other members in one’s networks, it can be expected that using Snapchat, which can remind users of their bonding social capital, may be more effective for brands to construct strong ties with their consumers. Therefore, the results of this research can be beneficial for brand managers creating SNS marketing plans.

The jet formed from the shaped charge with an aspect ratio of 2.73 and a higher strength liner than the conventional liner is shown to form a region where the temperature is higher than the melting point of copper, based on the result of the numerical analyses using an elastic-perfectly plastic constitutive model for the copper liner. This phenomenon is ascribed to the increased plastic work of the high-strength liner. From the result of numerical analyses using an appropriate strain-, strain rate-, and temperature-dependent constitutive model that can describe the stress upturn phenomenon of copper, the flow stress control of the high-strength copper liner is shown to be able to form an appropriate amount of melted volume, which increases the effective jet volume with a velocity higher than 2 km/s, fosters jet extension without breakage, and eventually increases depth of penetration in the target. Necessity of experimental verification for these findings is addressed together with a future activity to obtain the strain rate- and temperaturedependent fracture equivalent strain of the high-strength copper liner.

북한 역사학의 민족주의적 특징과 고대사 인식체계

김동후 동국대학교 북한학연구소 2022 북한학연구 Vol.18 No.2

Nationalism in North Korea has a greater influence on the studies of its history than historical materialism. It is no exaggeration to say that due to the influence of the Juche ideology, North Korea’s history is in fact within the framework of the nationalistic view of history. In the 1950s and 1960s, North Korea’s studies of history had been developed in a mixture of historical materialism and nationalism, and in the 1970s and 1980s, the nationalism tended to decline relatively as Kim Il-sung’s revolutionary history was emphasized due to Juche ideology. Then, in the 1990s, with the excavation of Dangunneung, nationalism in the historical studies of North Korea surged back once again centered on the “Taedong River Culture” theory. However, there are significant differences between the nationalism after the 1990s (referred to as “late nationalistic history”) and that before the 1990s (referred to as “early nationalistic history”). Most of these differences are criticized as being attributed to the politicization of North Korea’s ancient history research, but the analysis of what content and how to be criticized seems insufficient. Accordingly, this paper recognizes the problems of North Korea’s studies on ancient Korean history, but also denies wholly regarding North Korea’s recent research outcomes as the ramification of politicized nationalism. Throughout specific case studies, this study attempts to individually reveal whether those research results have been affected by North Korean nationalism and how positively South Korean researchers can accept those outcomes. This classification of North Korean research on ancient Korean history finally allows us to present a strategy for integrating ancient history between the North and the South. Given the consistency and falsifiability of an argument, therefore, North Korean nationalistic history can be divided into two categories: ‘Benign’ and ‘Malignant’. In this process, we are looking forward to having the ‘history of nationalism toward unity’ that the two Koreas can share together while paying attention to political ingredients in the North Korea’s study on ancient Korean history. 북한은 사적 유물론 이상으로 민족주의 역사학이 가지는 영향력이 지대하다. 1950~60년대에 북한은 사적 유물론과 민족주의가 혼재된 양상으로 역사학이 발전하고, 1970~80년대에는 주체사상으로 인해서 김일성 혁명사가 강조되면서 상대적으로 민족주의 역사학이 약화되는 경향을 보인다. 그러다가 1990년대 단군릉 발굴을 계기고 북한의 민족주의 역사학은 대동강문화론을 중심으로 다시 한번 재기의 발판을 마련하게 된다. 하지만, 1990년대 이후의 민족주의 역사학(후기 민족주의 역사학)을 그 이전의 민족주의 역사학(전기 민족주의 역사학)과 비교하면 확연히 다른 모습을 보여준다. 이러한 차이점을 대다수의 선행 연구에서는 북한의 고대사 연구가 정치화된 탓으로 비판은 하고 있지만, 구체적으로 어떤 내용으로 어떻게 비판받아야 하는지에 대한 분석은 미흡해 보인다. 따라서, 본 논문은 후기 민족주의 하에서 북한의 고대사 연구의 문제점을 인식하면서도 북한의 모든 연구 성과를 정치화된 민족주의의 결과로 환원시키기보다는 구체적 사례연구를 통해서 민족주의의 영향을 받았다고 인정되는 것과 그렇지 않은 것, 받았다 하더라도 긍정적으로 수용될 수 있는 부분과 그렇지 않은 부분을 개별적으로 분류하여 남북한 고대사 통합을 위한 전략을 제시하려고 하였다. 그 결과 주장의 일관성과 반증가능성을 감안하여 북한의 민족주의 역사학을 ‘악성’과 ‘양성’으로 구분하여 보았다. 향후 이러한 과정을 통해 북한 역사학의 정치성을 경계하면서도 남북이 함께 공유할 수 있는 ‘통합의 민족주의 역사학’을 가질 수 있기를 기대해 본다.
