To provide convenience and safety of drivers, the recent vehicles are being equipped with a number of electronic control units (ECUs). Multiple ECUs construct a network inside a vehicle to share information related to the vehicle's status; in addition, the CAN protocol is normally applied. As the modern vehicles provide highly convenient and safe services, it provides many types of attack surfaces; as a result, it makes them vulnerable to cyber attacks. The automotive IDS (Intrusion Detection System) is one of the promising techniques for securing vehicles. However, the existing methods for automotive IDS are able to analyze only periodic messages. If someone attacks on non-periodic messages, the existing methods are not able to properly detect the intrusion. In this paper, we present a method to detect intrusions including an attack using non-periodic messages. Moreover, we evaluate our method on the real vehicles, where we show that our method has 0% of FPR and 0% of FNR under our attack model.

Cause-Related Marketing is the process of formulating and implementing marketing activities that are characterized by an offer from the firm to contribute a specified amount to a designated cause when customers engage in revenue-providing exchanges that satisfy organizational and individual objectives. Many companies obtain benefits such as increasing sales profits and fulfilling social responsibility activities from Cause-Related Marketing as a strategic marketing activity. The purpose of this study is to analyze the effects of message of Cause-Related Marketing on consumer attitude, and to examine the moderating effects of ethical consumption propensity, social trust and types of product(utilitarian vs. hedonic) on consumer's product attitude. The research results show that consumers tend to adopt a positive attitude towards those advertisements with Cause-Related Marketing message. In the meanwhile, the ethical consumption propensity and social trust also have moderating effects on Cause-Related Marketing message's influence, but the types of product have no moderating effect. Based on the findings, the theoretical and managerial implication are discussed. In addition, some limitations of this study and future research directions are discussed.

본 논문에서는 시뮬레이션 모델을 통해 호유형뿐만 아니라 개인통신서비스에서 필수적인 핸드오버 및 위치등록 등의 모든 트래픽 유형을 고래했을 때 개인통신교환기(PCX : Personal Commuincations Exchange)에서의 지연시간을 분석하며, 지연시간에 대한 결과와 프로세서의 이용율로부터 개인통신교환기의 호처리 및 이동성처리용량을 분석하고 그에 따른 가입자의 수용능력을 추정한다. IPC(Inter-Processor Communications) 메시지의 송수신시간 및 메시지의 처리시간등 교환기 제어계의 성능분석에 필요한 입력 파라미터 값은 기존 ISDN(Integrated Services Digital Network) 및 CMS-MX(CDMA Mobile System-Mobile Exchange) 교환기의 측정자료를 이용하였다. 시뮬레이션 분석결과 PCX 교환기의 호처리 성능은 주로 번호번역 기능을 담당하는 프로세서인 NTP(Number Translation Processor)의 용량에 의해 결정되며, 가입자 밀도가 1,500명$/km^2$인 경우 호처리용량은 약 42만 BHC(Busy Hour Call Completion)로 추정되었고, 이에 상응하는 핸드오버 및 위치등록 처리용량은 각각 시간당 약 2만 6천히 및 40만 6천회로 나타났다. 이것은 가입자당 호처리 부하가 1.6BHC일 경우, 약 15만 7천 가입자를 수용할 수 있는 용량에 해당한다.

Currently, chatbot, a conversational platform based on artificial intelligence, is drawing attention as a new marketing channel. This study attempted to verify the effect of the anthropomorphism, message type, and media self-efficacy level on purchase intention. The experimental design of this study was a 2 (anthropomorphism level of shopping chatbot: low vs. high) × 2 (message type: factual vs. evaluative) × 2 (media self-efficacy: low vs. high) three-way mixed analysis of variance (ANOVA). This study conducted a survey by the convenience sampling method of 402 women in their 20s and 30s living in Seoul and the Gyeonggi area who were aware of chatbot services. For the final analysis, 388 questionnaires were used. Data were analyzed with the SPSS 23 program and three-way ANOVA. Simple main effects analysis was conducted. The results of this study were as follows. First, there were statistically significant differences in purchase intention according to anthropomorphism level, message type, and media self-efficacy. Second, message type and media self-efficacy showed statistically significant interaction effects on purchase intention. Lastly, anthropomorphism and the media self-efficacy level and the message type of the shopping chatbots showed significant three-way interaction effects on purchase intention.

With the development of cultural industries and technology, digital video marketing has grown immensely and 'Book Trailer' are now one of the main methods of promoting a title in publishing industry. The demands are growing, but the development lacks basic theoretical foundation and systematic structure. At this crucial moment, basic theoretical research on Book Trailer is necessary to establish a solid foundation for the medium to expand. In this study, I have focused on defining the basic concepts of Book Trailers and analyzing the classification of Book Trailers. In sorting the type of Book Trailers, content and formal appearance were used as standards. As a result, I was able to classify the content genre into message type, conflict type, character type using the elements of story. The formal appearance genre was classified into still photography type, motion typography type, interview type, story movie type and animation type.

The current study explored the relative effects of reciprocal/empathic type on messages appealing to help patients with Lou Gehrig's disease and their family. By this, we attempted to examine the applicable scope of the reciprocal type, a way of appealing rationally in the delivery of helping messages. The focus was on the moderation of empathic concern trait, a representative altruistic personality. Conducted as the online experiment, empathic concern trait was measured in the first stage, and the helping messages presented each by reciprocal/empathic type were shown and evaluated in the second stage after about 7 days. The data of 134 people were finally analyzed, excluding insincere participants. As a result, the relative advantage of empathic type was shown, but it was only limited to the subject attitude. In the result of the interaction, the reciprocal type were as much or more influential as the empathic type for the individuals high in empathic concern trait.

The current study challenges to suggest an umbrella strategy applied to different type of crisis, which is different from normative principle in crisis communication. The umbrella or comprehensive strategy in this study is identification framing. Identification framing is strategic message for organizational identification, which is close to social identification. The current study employed experimental design manipulating crisis types, crisis response types, and identification framing. The crisis types were internal versus external crisis, crisis responses were denial versus apology, and using identification framing $2{\times}2{\times}2$ factorial design were used. Two hundreds forty students participated in the experiment. The result showed the significant effectiveness of identification framing in different crisis types and crisis responses.
