본 연구의 목적은 액티브 시니어의 모바일 앱 사용 수준이 라이프스타일과 삶의 만족도에 미치는 영향을 미치는 정도를 파악하는 데 있다. 이를 위해 전국적으로 이용자 150여명을 대상으로 2021년 12월 초에 15일 동안 설문조사를 수행하였다. 설문내용으로 독립변수는 "모바일 앱 사용 수준", 매개변수는 "라이프스타일", 종속변수는 "삶의 만족도"로 구성하였다. 실증분석 결과, 각 변수 간 신뢰도 및 탐색적 요인이 검증되었고 내적 일관성도 확보된 것으로 확인하였다. 각 항목들의 집중타당성이 일반적으로 잘 확인된 것으로 조사되었다. 구조방정식에 의한 가설검증결과, ''앱 사용 수준 ⇨ 라이프스타일' 0.244로, '라이프스타일 ⇨ 삶의 만족도' 0.707, '앱 사용 수준 ⇨ 삶의 만족도 0.141'로 채택되었다. 액티브 시니어의 모바일 앱 사용 수준이 높을수록 라이프스타일이 높아질 것이고, 라이프스타일이 향상될수록 삶의 질이 향상될 것이며, 모바일 앱 사용 수준이 높아질수록 삶의 만족도가 향상될 것으로 분석되었다. 따라서 삶의 만족도를 향상시키기 위해서는 앱 사용 수준과 라이프스타일을 높이기 위한 노력이 필요해 보인다.

스마트폰, 태블릿PC와 같은 모바일 기기의 확산과 더불어 앱의 보급도 크게 늘어나면서 우리 일상의 다양한 분야에서 활용되고 있다. 게임, 생활, 엔터테인먼트, 정보, 전자상거래 등 다양한 종류의 수많은 앱이 생겨나고 있으나, 그들 중 대부분이 사용자의 구매 선택조차 받지 못하고 있으며, 구매가 이루어진 이후에도 많은 수는 오랫동안 사용되지 않고 외면당하고 있다. 사용자가 앱을 선택하고 사용하는 데에 영향을 미치는 요인을 찾는 연구는 사용자에게 적합한 앱을 선별적으로 추천하는 데에 활용됨으로써 마케팅 효과를 높일 수 있다는 점에서 앱 개발자나 배포자 및 사용자 모두에게 기여하는 실무적 가치가 크다고 할 수 있을 것이다. 이런 관점에서, 본 연구는 앱의 사용에 영향을 미치는 요인이 앱 유형별로 어떻게 달라지는지를 파악하려는 목적에서 수행되었다. 앱 사용에 영향을 미치는 요인으로서 사용자의 인구통계학적 특성뿐만 아니라 사용자가 앱을 구매하고 사용한 경험, 구매 시 참고한 앱에 대한 객관적 평가인 별점, 마케팅의 수단으로서 상품의 소개 화면에 노출되는 배지(Badge)의 영향을 살펴보았다. 사용자의 앱 선택에 영향을 미치는 요인에 대한 기존 연구들은 대부분 설문에 대한 응답 결과를 분석에 사용함으로써 사용기록이 정확히 반영하지 못하는 한계점을 갖는 반면, 본 연구는 특정한 기간 동안 사용자의 실제 사용기록 전체를 측정하고 수집하여, 이 데이터를 기반으로 분석을 실시했다는 점에서 큰 의의를 갖는다고 할 수 있다. 사용자가 자신의 모바일 기기에 설치된 다양한 앱을 설치해놓고 이들 중 자신의 필요에 적합한 것을 선택하여 사용하게 되는데, 이 선택에 영향을 미치는 요인이 카테고리 별로 다를 것이라는 점을 고려하여, 다변량 프로빗 모형을 활용하여 분석을 실시하였다. 분석결과로 앱 사용에 영향을 미치는 요인이 앱 카테고리 별로 달라지는 것과 앱 카테고리 선택 간의 상관관계를 제시하였으며, 사용자의 앱사용 목적에 따라 쾌락성(Hedonic)과 실용성(Utilitarian)으로 구분지어 설명하였다.

웹과 스마트폰의 사용이 일상화 되면서 맵 응용에 대한 수요가 웹 및 모바일 환경에서 급증하고 있다. 웹 기반 맵 응용들은 대부분 ArcGIS와 같은 값비싼 개발 환경이나 MapServer와 같은 공개 개발 환경에서 작성되고 있고 모바일 맵 응용들은 Google Maps나 Yahoo Maps와 같은 API 수준에서 작성되고 있다. 그러나 이러한 개발 환경들은 자동화 지원 정도가 미약하여 맵 응용 개발의 많은 부분이 아직 수작업에 의존하고 있다. 우리가 설계하고 구현한 MapAppGen은 신속한 웹 기반 맵 응용의 작성을 지원하기 위해 Drupal CMS(Contents Management System)에 적용 가능한 맵 관련 모듈들을 생성해 줌으로써 맵 응용에 대한 생산성을 향상시켜 준다. MapAppGen으로 생성한 응용은 Drupal이 지원하는 기존의 GMap이나 NodeMap이 생성한 응용에 비해 관심의 대상인 지형/지물과 함께 이 지형/지물과 연관된 모든 정보를 검색해 표시한다. MapAppGen은 Google Maps API를 사용하며 Drupal은 컨텐츠의 생성, 구성, 관리를 지원하는 모듈 기반 시스템이다. 향후, MapAppGen을 확장하여 모바일 맵 응용의 자동 생성도 지원할 예정이다.

Objectives: A mobile health intervention program was provided for employees with overweight and obesity for 12 weeks, and a process evaluation was completed at the end of the program. We investigated participant engagement based on app usage data, and whether engagement was associated with the degree of satisfaction with the program. Methods: The program involved the use of a dietary coaching app and a wearable device for monitoring physical activity and body composition. A total of 235 employees participated in the program. App usage data were collected from a mobile platform, and a questionnaire survey on process evaluation and needs assessment was conducted during the post-test. Results: The engagement level of the participants decreased over time. Participants in their 40s, high school graduates or lower education, and manufacturing workers showed higher engagement than other age groups, college graduates, and office workers, respectively. The overall satisfaction score was 3.6 out of 5. When participants were categorized into three groups according to their engagement level, the upper group was more satisfied than the lower group. A total of 71.5% of participants answered that they wanted to rejoin or recommend the program, and 71.9% answered that the program was helpful in improving their dietary habits. The most helpful components in the program were diet records and a 1:1 chat with the dietary coach from the dietary coaching app. The barriers to improving dietary habits included company dinners, special occasions, lack of time, and eating out. The workplace dietary management programs were recognized as necessary with a need score of 3.9 out of 5. Conclusions: Participants were generally satisfied with the mobile health intervention program, particularly highly engaged participants. Feedback from a dietary coach was an important factor in increasing satisfaction.

Background and objective: The purpose of this study was to comprehensively analyze the user behavior in order to cope appropriately with the increasing demand for mountain usage of those in their 20s and 30s and to allocate resources efficiently. Methods: To analyze the behavior of mountain hiking users, an exploratory data analysis (EDA) was conducted on the data which had been collected in the app Tranggle. The main target are users in their 20s and 30s who visited the mountains in the metropolitan area in 2019-2020. Among them, we have selected data on the top 13 mountains based on the frequency of visits. After data pre-processing, mountain usage patterns were analyzed through statistical analysis and visualization. Results: Compared to 2019, the number of users in 2020 increased 1.36 times. The utilization rate of the well-established hiking trails has also increased. The usage of mountain on weekends (Saturday > Sunday) was still the highest, and the difference in the usage between the days of the week decreased. Outside of work hours, early morning usage has increased and night-time usage has decreased. There was no significant change in usages depending on activity type, level (experience point) and exercise properties. Conclusion: Since the COVID-19 outbreak, the usage of mountains has been changing towards low user density and short-distance trip. in the post-COVID-19 era, the function and role of forests in daily life are expected to increase. To cope with this, further research needs to be carried out with consideration of the wider demographic and social characteristics.

This study was conducted to figure the usage status and satisfaction of food-related smartphone applications by generic characteristics and food purchase attributes of Seoul area workers. The results show that health vitality-oriented group, married compared to single, those with higher eating-out expenses possess more food-related applications (p<0.05). The primary reason for the usage of food-related applications was the need for food-related information (53.7%). The highest application subjects in use were restaurant-related information and recipe information. The real-life aid food-related applications utilized most were also restaurant information (60.7%) and recipe information (28.3%). Health vitality-oriented respondents especially turned out to use nutrition information and food functionality information often (p<0.01), and recipes or calories & diet information usage frequency was higher in women than in men (p<0.001). Restaurant-related information were more frequently used by singles, highly educated, and those with high income and eating-out expenses (p<0.05). Satisfaction of food-related applications was normal (3.06), showing that the satisfactory level is not yet high. Satisfaction regarding purchase attributes showed that the health vitality-oriented group (3.19) was more satisfied compared to other groups (p<0.05), and women (3.16) were more satisfied that men (2.89) were (p<0.05). Inconveniences of food-related applications were highest in usage fee (3.29), simplicity of information (3.28), lack of reliability of information and need for update (3.10). The results of this study implies that various subdivisions of food-related applications users should be implemented; at the same time, food-related applications covering diverse subjects that regard each group's characteristics should be developed in order to utilize food-related knowledge and information as a marketing tool in the food industry; this can efficiently be done by paying attention to the quality of information and updates within applications.
