This study examines the adoption of subscription-based video on demand (SVOD) streaming services among consumers. Primarily, we explore the moderating effect of the two models of streaming services, standalone streaming services and bundled streaming services, on the users' adoption. We employ the Unified Theory of Acceptance and Use of Technology (UTAUT2) model in this study. We utilize the data collected from 337 Indian respondents and find that all constructs of the UTAUT2 model act as motivators of adoption. Gender, age, and experience of the respondent also play a moderating role in the adoption of streaming services. We also find that providing bundled streaming service positively moderates price-value and hedonic motivation of adoption. The study is perhaps the first of its kind that aims to understand the motivations for adoption of SVOD services, particularly in the Indian context, which has the fastest-growing base of internet users in the world.

최근의 급격한 과학 기술발전에도 불구하고 2000년대 이후 전 산업에 걸쳐 생산성 하락 현상이 나타나고 있다. 본 연구에서는 이러한 생산성 하락 현상을 아마존, 알파벳, 애플 등 일부 지배적 기업의 출현과 성장 그리고 인수합병 추이를 기반으로 산업/개별 기업 수준에서 실증적으로 규명하고자 하였다. 기존 연구 결과와 유사하게, 본 연구의 분석 결과도 2000년대 이후 산업 수준에서의 생산성은 하락한 것으로 나타났다. 특히 2011년 이후 기간만을 고려하면, 지배적 기업군의 성장으로 인한 산업 내 분배적 효율성 악화 뿐 아니라 지배적 기업 비율이 낮은 산업군의 존속기업 성장률 하락도 산업 전반의 생산성 하락에 기여한 것으로 분석되었다. 반면, 개별 기업 수준의 생산성을 분석한 결과를 보면, IT 기업을 인수한 기업의 생산성은 전 기간에 걸쳐 향상된 것으로 나타났다. 인수합병의 동기는 전반적으로 생산성에 정(+)의 방향으로 영향을 주지만 기술획득, 생산비용 절감 등 공급 측면에서의 효율성 향상을 위한 인수합병 대비 시장침투, 시장정보 획득 및 채널 확대 등 수요 측면에 초점을 둔 인수합병이 상대적으로 더 큰 폭으로 생산성 증가에 기여한 것으로 나타났다. 마지막으로 산업 내 지배적 위치의 기업 비중이 높을수록 개별 기업의 생산성은 하락하는 것으로 나타났다. 디지털 중심으로의 산업구조 변화로 인해 거대 기업의 지위가 더욱 공고해지는 경향을 보이는 현 시점에서, 본 연구 결과는 거대 기업의 등장, IT/Non-IT 기업 인수, 인수합병의 동기 그리고 생산성 변동과의 관계를 실증적으로 규명하였다는 점에서 의의가 있다.

Culture is that the system of shared beliefs, values, customs, behaviors, and artifacts that the members of society use to cope with their world and with one another, and that are transmitted from generation to generation through learning. Members of an organization are affected by culture. And dissensions in an organization give negative effects to behavior of the members, especially to satisfaction from organization. This study is on the dissension management by considering of cultural characteristics of pilots. Cultural characteristics of pilots were surveyed and analyzed with the V5M94(values survey module94) which was developed by Hofstede. As results, the cultural indexes of the pilots were different from the national means. The indexes presented that korean pilots' cultural characteristics are low POI, high IDV, low MAS and low UAI as North European cultural characteristics. For managing the pilots group, make expansion of opportunity to take part in decision making, release or share of informations are required. And motivations, delegation, free from unnecessary interventions, understanding and forgiveness rather than disciplinary punishment, thoughtful considerations could be effectiveness. And for developing more effective management methods, management strategies of north european airlines should be studied.

Machine learning model gained the popularity in recent years as multi-national companies have incorporated machine learning in their services. Such service is called machine learning as a service (MLaSS). Such services are provided to users based on charge-per-query which triggers the motivations for adversaries to steal the trained victim model to reduce the cost of using the service. Therefore, it is important for companies that provide MLaSS to protect their intellectual property (IP) against adversaries. It has been arms race between the attack and defence in a context of the privacy of machine learning models. In this paper, we provide a comprehensive study of recent development in protecting privacy of machine learning models.

Cancer illness representations and screening history among residents of Kolkata, India, were investigated along with socio-demographic characteristics in an effort to understand possible motivations for health behavior. A total of 106 participants were recruited from community locations in Kolkata, India and completed surveys including demographics, the illness perception questionnaire-revised (IPQ-R), and previous experience with cancer and screening practices. Participants were 51.5% college educated, 57% female, 51.5% full-time employed with average age of 32.7 years (R: 18-60 years). Descriptive statistics were generated for the subscales of the IPQ-R, cancer-screening practices and cancer experience. Correlation analyses were conducted to investigate associations between cancer representations and socio-demographic variables. Univariate ANOVAs were calculated to determine gender differences in IPQ-R subscales and differences between participants who knew someone diagnosed with cancer versus those who did not. While 76% of participants knew someone with cancer, only 5% of the sample engaged in cancer screening. Participants perceived cancer as a serious illness with negative emotional valence. Younger age (r(100)=-.36, p<0.001) and male gender (F(1, 98)=5.22, p=0.01, ${\eta}_2$=0.05) were associated with better illness coherence. Males also reported greater personal control (F(1, 98)=5.34, p=0.02, ${\eta}_2$=0.05) were associated with better illness coherence. Low screening rates precluded analyses of the relationship between illness representations and cancer screening. Cancer was viewed as a threatening and uncontrollable disease among this sample of educated, middle class Kolkata residents. This view may act as a barrier to seeking cancer screening. Public awareness campaigns aimed at improving understanding of the causes, symptoms and consequences of cancer might reduce misunderstandings and fear, especially among women and older populations, who report less comprehension of cancer.

Mobile fashion apps present much opportunity for marketers to engage consumers, however not all apps provide enough functions for their targeted audience. This study aims to determine how mobile fashion apps can be used to build brand community with consumer engagement. Qualitative data on fashion mobile apps were collected from the Apple app store and Android market during the spring and summer of 2015. A total of 110 fashion mobile apps were collected;, 50 apps were identified as apparel brands that either manufacture or sell apparel to consumers, which we categorized as "brand" fashion apps, and the remaining 60 were categorized as "non-brand" fashion apps. The result of the study can be summarized as below. The 60 non-brand fashion apps were grouped into 5 app types: shopping, searching, sharing, organizational, and informational. The main functions are for informational use and shopping needs, since at least half (31 apps) are used for either retrieving information or for shopping. However, in contrast, social networking and location were infrequent and not commonly utilized by these apps. The most common type of non-brand fashion apps available were shopping apps;, many shopping apps enable users to shop from several different websites and save their items into one universal shopping cart so that they only check out once. Most of these apps are informational and help consumers make more informed decisions on purchases;, in addition many offer location services to help consumers find these items in store. While these apps perform several functions, they do not link to social media. The 50 brand apps were grouped into 5 brand types: athletic, casual, fast fashion, luxury, and retailer. These apps were also checked for attributes to determine their functionality. The result shows that the main functions of brand fashion apps are for information (82% of the 50 apps) as well as location searching (72% of 50 apps). Conversely, these apps do not offer any photo sharing, and very few have organizational or community functions. Fashion mobile apps and m-marketing elements: To build brand community, mobile apps can be designed to motivate consumer's engagement with brands. The motivations of fashion mobile apps are useful in developing fashion mobile apps. Entertainment motives can be fulfilled with multimedia attributes, functionality motives are satisfied with organizational and location-based features, information motives with informational service, socialization with community and social network, learning and intellectual stimulation from informational attributes, and trend following through photo sharing. The 8 key attributes of mobile apps can correspond to the 4 m-marketing elements (i.e., Informative content, multimedia, interactions, and product promotions) that are further intertwined with m-branding elements. App Attributes and M-Marketing aim to Build Brand Community;, the eight key attributes can impact on 4 m-branding elements, which further contribute to building brand community by affecting consumers' perceptions of brands preference and advocacy, and their likelihood to be loyal.

The purpose of this study was qualitatively conducted for getting the answer of this problem by searching the beliefs of mathematics teachers with experience in technology and the factors that influences these beliefs. The participants in this study consist of eight teachers and one university professor having technological experiences from three years to ten years with a higher degree than M.A. The data was collected through focused group interviews for twice and individual interview as well. Data analysis was completed through several readings of transcripts and then main themes were derived by classifying, comparing, and contrasting codings. The result of this study showed that teachers with the experiences of technological tools have the concrete belief that technology helps both students and teachers understand mathematical concepts and enhance various representational activities and motivations. The result also identified the impeding factors of three beliefs of mathematics teachers. From these beliefs and factors, this study would suggest how to help teachers hold their beliefs about using technologies to improve their teachings and students' learning.

The purpose of the study was to explore the uses and gratification of social media among first-year student groups at a satellite campus of a public university in Ghana. The study employed a descriptive survey design. The study involved all 1061 first-year university students in six academic departments of the College. A total of 680 (64%) participants returned validly completed copies of the questionnaire. Descriptive statistics and thematic analysis were employed for data analysis. The findings indicate that WhatsApp was the most popular application for social media groups, while a need for information-sharing, peer-tutoring and learning, and finding and keeping friends were the primary motivations for joining social media groups. First-year students are involved mainly in reactive activities, as most engage when solving an academic assignment through group discussions. Though challenges persist, such as posting of unwanted images, inadequate participation, and ineffective and irrelevant communication, most are willing to continue their social media groups' membership in the long term. This study provides valuable insight into transitioning students' lived experiences on social media from the group perspective. These insights are valuable conceptually and practically to academic counsellors, librarians and student affairs officers who are expected to provide on-going education on (social) media literacy to first-year students to enhance the adjustment process. The study is the first of its kind in Ghana that investigates social media group participants' exit intentions.

전 세계적으로 기업의 중요한 전략적 수단으로 인수합병이 활발히 이루어지고 있고, 지능형 서비스 산업을 포함한 정보기술 산업에서의 인수합병 활동은 꾸준히 활발하게 진행되고 있다. 본 논문에서는 정보기술 산업 내에서 일어나는 인수합병 건에 대해 인수 기업 입장에서의 인수 의도에 초점을 두고 분석하였다. 특히, 두 하드웨어 기업 간, 하드웨어 기업 소프트웨어 기업 간, 두 소프트웨어 기업 간 인수합병 유형에 따라 인수 의도가 어떻게 다른지 비교하고자 하였고, 이를 위해 미국 정보기술 산업 내에서 1995년과 2010년 사이에 일어났던 1003개의 인수합병 건의 자료를 분석하였다. 인수 의도를 파악하는데 있어, 인수 기업의 입장에서 생산비용 절감 의도, 제품 개발 및 개선 의도, 고객층 확장 의도, 고객채널 확장 의도의 네 가지로 구분하여 측정하였다. 분석 결과 생산비용 절감 의도와 고객층 확장 의도는 하드웨어 기업이 피인수 기업일 때 더 많이 나타났고, 제품개발 의도는 하드웨어 기업이 인수 기업일 때 더 많이 나타났다. 그리고, 고객채널 확장 의도는 소프트웨어 기업이 피인수 기업일 때 더 많이 나타났다. 또한, 생산비용 절감 의도, 제품 개발 및 개선 의도를 제품생산 관련활동 의도로, 고객층 확장 의도와 고객채널 확장을 고객관련 활동 의도로 구분하여 비교하였을 때에는, 하드웨어 기업 간 인수합병에 비해, 두 소프트웨어 기업 간 인수합병에서 상대적으로 고객관련 활동 의도가 높은 비중을 나타내고 있음을 알 수 있었다. 활발하게 인수합병이 이루어지고 있는 세계적 추세와는 달리 국내 인수합병거래 규모는 선진국에 비해 매우 적은 수준이다. 본 연구는 인수합병이 보다 활발하게 이루어지고 있는 미국기술정보 산업에서의 인수 의도를 분석하여, 국내에서 인수합병 활동을 활성화하는 방안을 분석 및 개발하는데 기여하고자 한다.
