This study want to identify problems related to mobile in-app payment from the perspective of consumers and suggest ways to solve them. Three scenarios have been developed to achieve the objectives of this study. This suggests the situation of in-app payment problem that consumers often experience. Then 323 consumers in their 20s and 30s read the scenario, identified the problem in each situation and assessed who was responsible. Consumers were aware of in-app payment problems due to problems with in-app payment readability, problems with app market responsibility, problems with responsibility of game companies, and problems of consumer responsibility. And different consumers had different levels of assessment on the problem of in-app payment. According to the research, consumers have high demand for improvement of the lack of readability in related laws, including strengthening the readability of the in-app payment indicator. In addition, the company confirmed the importance of cooperative efforts by consumers, businesses, and the government due to high consumer expectations for the role of the distribution company App Market other than the content developer game company.

최근의 자연 재난의 발생 빈도의 증가는 재난에 대한 정보전달의 중요성이 높아지는 만큼 전달 방법의 중요도도 높아지고 있다. 특히, 2020년의 코로나19(COVID-19)로 인하여 자연 재난에 더해 사회재난에 관한 관심도 증대하고 있으나, 재난정보의 빈도가 매우 높아져, 2000년대 통틀어서 제공된 재난 정보량보다 20년, 21년의 재난 정보량이 더 많아 보인다. 이러한 재난정보의 홍수는 반대급부로 정보의 피로도를 증가시켜 의도적 또는 비의도적 무시 경향을 유발할 수 있다. 이에 본 논문에서는 재난 위험지역을 기반으로 Segment를 생성하고 관리하며, Segment 단위로 재난 위험 메시지를 제공하는 Segment기반 긴급메시지전송 시스템을 연구한다. 목표시스템에서는 재난정보를 실황 정보와 1시간 예측정보를 비교, 위험지역 회피시나리오를 지능화 개선하여 모바일앱 이용자에게 제공함으로써 대피 이동관리와 행동 유도를 이끌어 이용자의 인명피해 저감과 재산손실 감소의 효과를 얻고자 개발하였다.

보편적으로 사용되는 경로 검색 앱은 출발지에서 목적지까지의 최단 거리 또는 최소 시간을 기준으로 도보 경로를 추천하고 있어 사용자의 다양한 요구사항을 반영하는데 한계가 있다. 이러한 문제를 해결하기 위하여 본 논문에서는 사용자의 일정 및 본인의 섭취한 칼로리를 기준으로 출발지와 목적지 사이의 다수의 경로를 추천하는 앱을 제안하였다. 또한, 제안된 앱의 동작을 검증하기 위하여 해당 기능을 직접 구현하고 다양한 테스트시나리오들을 이용하였다.

In this paper, we investigated the following items for the development of gas safety work mobile app. In this study, which is a follow-up study after the completion of the scenario design and the first, second image extraction of the mobile app based on the initial research that has been studied, 1) Suggested classification of gas works by type classification and risk classification 2) The research and proposal of interaction method for effective interworking of mobile app and worker in many industrial fields of two-hand work have been made. In particular, the development of a mobile app that interacts with the main system that manages not only the gas work but also the field of each industrial field is the first attempt in Korea and has helped the worker to work freely and safely through various interaction methods.

Recently, school violence problem has increased serious. And this is not only an individual issue but also this is a social problem. Realistically, not only physical violence, cyber violence using the smartphone is very serious. And if the elementary school students are exposed to cyber violence, it becomes even more serious problem. Therefore, we proposed an Smart Monitoring app that protect the smart safety such as as a countermeasure against cyber violence to elementary school students. This Conversion Smart app can support grasp service for children using location based service on the smartphone when he will come to the home. And it can support another service that abuse or vulgar language in messenger. Grasps the degree of use of the language that is prohibited friendship in elementary school through this process, it can be derived. And we have future works that is the search rate and response time an inappropriate word on the proposed system.

Based on the theory of cognitive reserve, we undertook this study to develop a cognitive function training program for woman in menopausal transition with complaints of declining in cognitive function. The program was established by applying the analysis, design, and development stages of the network-based instructional system designed by Jung. The cognitive function training program developed by us is an was an 8-week program composed of cognitive and video training using a mobile application. The program consists of 24 sessions, each with 20-30 minutes of duration, to be completed 3 sessions per week. The contents of the cognitive function training comprise of memory, attention, language function, and scenario-based problem-solving for executive functions, all of which are cognitive areas found to be the most vulnerable for menopausal women. The educational contents were developed for eight subject areas, one subject area per week, including the definition of menopause, its causes and symptoms, menopause and brain function, etc. During the pilot test, the cognitive function training program was applied to 10 menopausal women who complained of cognitive function decline. The results indicated that, after eight weeks of training, the overall cognitive function of participants increased, revealing statistically significant differences (t=-3.04, p=.014) after the program was completed. The mobile app-based cognitive function training program might not only improve patients' memory functions but also potentially reduce the incidence of dementia.

In this paper, we propose a barrier-free course route navigation service named "Theme Road" aimed at improving the mobility and convenience for elderly electric wheelchair users with walking disabilities. To achieve this goal, we conducted a user survey through shadowing and in-depth interviews to gather insights on the challenges experienced by elderly electric wheelchair users. We identified potential solutions for each inconvenience through co-creation workshops, resulting in a set of design considerations and app functionalities. Using persona development and service scenarios, we designed and implemented the "Theme Road" service as a dedicated navigation application for barrier-free course navigation. Unlike conventional route navigation and mapping services, our study stands out by offering a unique approach that combines recommended destinations and safe routes based on experiential analysis from elderly electric wheelchair users.

With a wide dissemination of smartphones, the number of native applications developed and sold freely by anyone is growing now. The application market activated by Apple's App Store is spreading more rapidly with Google's Google Play. But due to platform-dependent of native application's attribute, developers are programming at each platform. As a result, development cost is increasing compared to earnings. To solve a dependency problem, people focused on web application developed by web-based language. However, stores at each browser are requiring a web application to follow manifest format. And this causes browser-dependent problem. Those problems can be solved by installing a certain browser, but this can make an application useless on the other browser of a store. Dependency problem can narrow not only user's application variation, but also concentration on some specific store. OWS(Open Web Store) is a standard store that supports various web environments. It overcomes browser or platform dependency problems by interworking applications between stores. Also customers are able to choose a large number of applications. In this paper, related to OWS, I would like to suggest manifest standards and store's reference architecture. An interworking scenario is going to be proposed as well.
