본 연구는 국내 시장에서 활발히 사용 중인 모빌리티 O2O 서비스 카카오T 애플리케이션을 중심으로 사용성 평가를 통해 카카오T만의 차별성과 개선방안을 도출하는 데 목적이 있다. 1차로 모빌리티 O2O 서비스 시장에 대한 현황을 파악하고, 2차로 카카오T 애플리케이션의 주요 기능과 전반적인 인터페이스를 중심으로 피터 모빌(Peter Morvile)의 허니콤 모델(Honeycomb model) 사용성 평가 원칙을 5가지로 재구성하여 심층 인터뷰를 실행하였다. 그 결과, 첫 번째로 모빌리티 서비스로서 수요와 공급의 불균형에서 오는 문제점이 있지만 앞으로 추가될 기능인 카풀을 통해 개선될 것으로 보인다. 두 번째로는 기존의 기능별 애플리케이션이 존재하는 상황에서 카카오T에 합쳐진 기능들의 필요성을 인지하지 못하는 것에 대한 문제점이 도출되었다. 본 연구를 바탕으로 도출된 개선방안은 모빌리티 O2O 서비스 사용자의 편의성을 증진하고 플랫폼을 강화하는 데 도움이 될 것으로 기대된다.

Purpose: This research focused on the fact that the Internet platform is integral to IoT products such as Smart home and studied consumer buying decisions when products are sold bundled with internet service. Contrary to the sales strategies of telecommunication companies, some companies sell IoT products alone, for example Google, Kakao, and Naver. In this market situation, the sales strategies of Korean telecommunication companies were analyzed with bundling theory and technology acceptance model, then it was conducted to figure out which sales and distribution strategies could affect consumers' purchase behavior. Research design, data, methodology: Data was collected by149 questionnaires from groups who are familiar with IoT smart home systems, then exploratory factor analysis and regression were used to analyze the research model. Results: The results revealed that the perceived ease of use and the perceived usefulness affect the purchase intention of IoT-based products; however, this effect was not found in the case of bundled products. In other words, it is found that selling and distributing Internet services and IoT products together does not affect consumers' purchases. Conclusion: It is suggested that Korean telecommunications companies' existing sales and distribution strategies for IoT products need to be changed according to its characteristics.

현재 영어 기반의 기술 팩트체크 서비스는 다양하지만 한국 기반 팩트체크 서비스는 비기술적(언론인 등 전문가의 교차 검증을 통한 팩트체크)이 주를 이루고 있으며, 기술 팩트체크 서비스가 많이 시행되지 않고 있다. 본 논문에서는 기술적인 요소와 비기술적인 요소의 서비스를 함께 사용할 때 허위 정보를 가장 정확하게 식별할 수 있기 때문에 한국어 기반의 자연어 처리 기술을 이용한 팩트체킹 서비스를 제안한다.

Purpose: To identify the effects of a smart program for the patients who underwent percutaneous coronary intervention (SP-PCI) on coronary disease-related knowledge, health behaviors, and quality of life. Methods: A nonequivalent control group with a non-synchronized design was utilized and 48 participants (experimental=22, control=26) were recruited from a university hospital in Gyeongsang area from May to December, 2016. The 12-week SP-PCI consisted of self-study of health information using smart phone applications (1/week), walking exercise (>5/week) using smart band, feedback using Kakao talk (2/week), and telephone counseling (1/week). Patients in the control group received usual care from their primary health care providers and a brief health education with basic self-management brochure after the PCI. Data were analyzed using the SPSS 21.0 program through descriptive statistics, $x^2$ test, and t-test. Results: After the 12-week SP-PCI, the experimental group showed higher levels of coronary disease-related knowledge (t=2.43, p=.019), heart-related health behaviors (t=5.96, p<.001), regular exercise (Z=-4.47, p<.001), and quality of life-MCS (t=3.04, p=.004) and showed lower levels of stress (Z=-3.53, p<.001) and sodium intake (t=-4.43, p<.001) than those in the control group. There were no significant group differences in medication adherence and food intake in total energy, lipids, and cholesterol. Conclusion: The suggested SP-PCI provided easy access and cost-effective intervention for patients after PCI and improved their knowledge of the disease, performance of health behaviors, and quality of life. Further study with a wider population is needed to evaluate the effects of SP-PCI on disease recurrence and quality of life for patients after PCI.

In the process of online trading, many unexpected conflicts may occur. The consumer wishes to perform transactions with a seller by trusting the seller's listings, but there are times when even major companies such as Kakao edit their original listings. When the seller edits their listing, it is extremely difficult for the consumer to prove and deal with the problem. If they don't deal with them carefully they may be accused of denigration. This study proposes a consumer protection system to resolve this problem. In case a problem occurs, proof that the original listing was edited can be submitted to a judge in court by using this system, thus preventing these types of problems from happening. If this system is installed, both the seller and consumer know that the terms of contract cannot be falsely changed to the advantage of either side, so the source of the problem can be prevented. This study analyzes the reasons behind the conflicts and presents a systematic way of preventing the problem. This method does not present a financial burden, and provides a way for transactions to be held based on trust for the seller and consumer.

Objectives: The purpose of this study is to identify the problems of verbal violence that adolescents face in the post-human age, when the non-face-to-face media is increasing. Methods: A survey was conducted on 305 adolescents, aged 14 to 16 years of middle school and high school students. The data were analyzed with the SPSS 25.0. Results: As a result of conducting multiple regression analysis to identify the type of conversation that affects verbal abuse of adolescents, a model with a conversation with family, conversation with other people, messenger conversation such as KakaoTalk, and video chat conversation was selected. The amount of explanation was 11.4%. (R2 = .114) Of these, non-face-to-face conversations have been shown to increase verbal violence, and face-to-face conversations with family have, in turn, lowered the risk. As a result of t-testing to examine the effect of verbal abuse experience on the verbal violence index, the damage experience was significant in depression (p = .042) and impulsive aggression (p = .021). (P = .000). Conclusion: This study reiterates the importance of family dialogue along with the fact that the development of various non-face-to-face media in the Fourth Industrial Revolution can have a negative impact on adolescent mental health.
