As interest in the Internet increases, related technologies are also quickly progressing. As smart devices become more widely used, interest is growing in words are missing here like "improving the" or "figuring out how to use the" future Internet to resolve the fundamental issues of transmission quality and security. The future Internet is being studied to improve the limits of existing Internet structures and to reflect new requirements. In particular, research on words are missing here like "finding new forms of" or "applying new forms of" or "studying various types of" or "finding ways to provide more" reliable communication to connect the Internet to various services is in demand. In this paper, we analyze the security threats caused by malicious activities in the future Internet and propose a human behavior analysis-based security service model for malware detection and intrusion prevention to provide more reliable communication. Our proposed service model provides high reliability services by responding to security threats by detecting various malware intrusions and protocol authentications based on human behavior.

A study on what kind of problems young consumers experience in buying and using mobile phone services with a comprehensive and consumers oriented perspective is needed. Through this acknowledgement, we investigated (i) the degree of consumer problems that young consumers experience in purchasing and using mobile phone services, and (ii) the related variables that affect experiences of this consumer problem. The parents of the teenagers were also included in the survey because they experience the same problems young consumers' experience in buying and using mobile phone services. Data were gathered through an internet survey (www.embrain.com) and a total of 699 samples from 350 parents and 349 youths using mobile phone services were analysed. The results are as follows. First, the teenagers and parents' experience level of young consumers' problems were generally high experiencing similar kinds of problems. Second, parents experienced more young consumers' problems than the teenagers in buying and using mobile phone services, especially in misuse and abuse of the phones. Third, among the teenagers, the monthly usage fee music or game usage, the number of changes in mobile phone service operators, the number of replacement mobile phones and the gender had a significant effect on consumers' problems of mobile phone services. Among the parents, the monthly usage fee, music or game usage, confirmation of the bill, and the gender of their child were significant consumer problems. Based on results of our survey the direction of consumer policy and education was suggested for teenagers and their parents.

The online fashion market in the 21st century has shown rapid growth. Against this backdrop, using consumer activity data to provide customized customer services has emerged as a viable business model that draws attention. Algorithm-based personalized recommendation services are a good example. But their application in fashion products has clear limitations. It is not easy to identify consumers' perceptions of the attributes of fashion, which are various, hard to define, and very sensitive to trends. So there is a need to compile data on consumers' underlying awareness and to carry out defined research to increase the utilization of such services in the fashion industry and further engage consumers. This research aims to classify the attributes and types of fashion products and to identify consumers' perceptions of a given situation where a recommendation service is offered. To find out consumers' perceptions of and satisfaction with recommendation services, an online and mobile survey was conducted on women in their 20s and 30s, a group that uses recommendation services frequently. A total of 455 responses were used for analysis. SPSS 28.0 was used, combined with Conjoint Analysis and multiple regression, to analyze data. The study results could provide insights into a better understanding of recommendation services and be used as basic data for companies to identify consumers' preferences and draw up a detailed strategy for market segmentation.

The main objective of this study is to investigate the factors affecting patient satisfaction, repeat-use intention, and inducement intention for providing the suggestion for patient-oriented management of dental services organizations. For this study, the patient satisfaction model including 14 facets of satisfaction factors such as distance(time/location), human services(dentist-hygienist), treatment results, and facilities(convenient facilities/parking lot) was examined. Data were collected from 196 patients who visiting the same dental services organization more than two times of ten dental clinics at Kyeongsangnam-do area using self-administered questionnaire. Major results of the empirical analysis are as follows: First, patient satisfaction, repeat-use intention, and inducement intention were significantly correlated with gender, age, economic conditions among patients of dental clinics. Second, kindness of hygienist, treatment results, kindness of receptionist, waiting time, emergency medical services, and right-fee for services were found to have significant influence on dental services organizations. These research findings suggest that improvement of service quality in dental care and advancement in treatment ability of dentist and hygienist are very important to improve patient satisfaction and patient-oriented service system in dental services organizations.

Network human-robot interface is an important research topic. In home application, users access the robotic system directly via voice, gestures or through the network. Users explore a system by using the services provided by this system and to some extend users are enable to participate in a service as partners. A service may be provided by a robot, a group of robots or robots and other network connected systems (distributed sensors, information systems, etc). All these services are done in the network environment, where uncertainty such as the unstable network connection, the availability of the partners in a service, exists. Moreover, these services are controlled by several users, accessing at different time by different methods. Our research aimed at solving this problem to provide a high available level, flexible coordination system. In this paper, a multi-agent framework is proposed. This framework is validated by using our new concept of slave agents, a responsive multi-agent environment, a virtual directory facilitator (VDF), and a task allocation system using contract net protocol. Our system uses a mixed model between distributed and centralized model. It uses a centralized agent management system (AMS) to control the overall system. However, the partners and users may be distributed agents connected to the center through agent communication or centralized at the AMS container using the slave agents to represent the physical agents. The system is able to determine the task allocation for a group of robot working as a team to provide a service. A number of experiments have been conducted successfully in our lab environment using Issac robot, a PDA for user agent and a wireless network system, operated under our multi agent framework control. The experiments show that this framework works well and provides some advantages to existing systems.

서비스 현장에서 로봇의 활용이 증가하고 있다. 본 연구는 서비스 로봇의 종업원으로서의 역할에 주목하여, 로봇의 서비스가 고객행동에 어떠한 영향을 주는지를 서비스 성공과 실패 상황에서 사람 종업원과 비교하여 살펴보았다. 바리스타로봇, 서빙로봇, 쉐프로봇을 대상으로 세 번의 실험을 통해 실증분석을 수행하여 도출된 결과는 다음과 같다. 먼저, 서비스가 성공적인 경우, 사람들은 서비스를 제공한 종업원이 사람인지, 로봇인지에 관계없이 재방문 의도가 유사하게 나타났다. 반면, 서비스가 실패인 상황에서는 로봇 종업원으로부터 서비스를 받은 경우보다 사람 종업원으로부터 서비스를 받은 경우에 재방문 의도가 더 부정적인 것으로 나타났다. 이에 대한 이유는 아직까지 서비스 로봇의 능력에 대한 고객들의 기대가 사람 종업원에 비해 낮기 때문인 것으로 파악되었다. 마지막으로 고객들은 로봇의 서비스가 사람의 서비스에 비해 더 안정적이라고 인식하는 것으로 나타나 서비스 로봇이 성공적인 서비스를 제공한다면 로봇으로부터 서비스를 제공받는 고객으로부터 긍정적인 반응과 행동을 이끌어낼 수 있을 것으로 예상된다.
