This study aims to identify the contents characteristics of fine dust management apps currently released in Korea and evaluate the quality level. Methods: We found 400 apps to search for keywords related to fine dust, and 30 apps that meet certain criteria were selected as the final research subjects. It describes the main content status of 30 apps. Additionally, we evaluate the quality level of the app by utilizing the mobile application rating scale (MARS). We analyze the correlation between MARS Score, consumer score, and number of reviews. Results: Most fine dust apps were providing contents that provide fine dust concentration based on global positioning system (GPS). According to the MARS evaluation, engagement was low in average score, and in aesthetic, the gap between apps was large. The correlation analysis between the scores was not significant. Conclusions: It is necessary to develop differentiated contents such as personal health records and monitoring in order to increase the motivation and sustainability of using the fine dust mHealth app.

본 연구의 목적은 (1) 20대 청년들의 전반적인 건강행태를 집단별로 분류하여 파악해보고 (2) 청소년에서 청년 이행 시 변화하는 건강행태 위험비 추이를 살펴보고자 한다. 연구방법: 연구자료는 한국고용정보원의 청년패널조사 4개년 자료(2009, 2012, 2015, 2018) 자료를 사용하였다. 건강행태 지표는 음주, 흡연, 수면시간, 신체활동을 활용하였다. 20대 청년들의 건강행태는 건강행태지표에 따라 집단별 건강행태 위험비를 4개년 각각 산출하여 위험비 추이를 파악하였다. 청소년에서청년 이행 시 건강위험행태의 변화를 파악하기 위해 과거와 현재 청년 코호트를 구분하고, 각 코호트의 성인기 진입 시 변화하는 건강행태 위험비를 산출하였다. 연구결과: 20대 청년의 집단별 건강행태 특성은 과음 및 흡연의 경우 취업자 집단이 가장 높은 위험비를 나타냈다. 또한 수면시간 부족은대학원생 집단에서 가장 위험비가 높았다. 최근 청년(97~99년생)코호트가 과거 청년(91~93년생)에비해 청소년에서 청년으로 이행 시 변화하는 건강위험행태의 위험비가 과거보다 증가하였다. 결론: 우리나라 성인의 건강행태가 전반적으로 개선되고 있는 반면 청년층은 그렇지 않다는 것을 확인하였다. 향후 청년의 건강행태를 지속적으로 모니터링할 필요가 있으며, 청년층에 대한 단일화된 건강대책보다는 집단별로 분류하여 건강대책을 다각화할 필요가 있다. Purpose: The purpose of this study is to (1)identify the overall health behavior of youth in their 20s by grouping them and (2) to examine the changing risk ratio of health behavior among teenagers to adults. Methods: The research data were used by the Korea Employment Information Service(KEIS) for four years (2009, 2012, 2015 and 2018) of the Youth Panel Survey. Health behavior indicators used drinking, smoking, sleeping hours, and physical activity. Youths were classified into four groups to identify the characteristics of health behaviors by groups in their 20s. After that, the risk ratio for each group was calculated for each of the four years by using the unemployed as a reference variable for each health behavior index. In order to identify changes in health risk behavior in youth transition, the past (born 91-93) and present (born 97-99) youth cohorts were divided and the risk ratio of changing health behaviors was calculated when each cohort entered adulthood. Results: The characteristics of group health behavior of youth in their 20s showed the highest risk ratio of the employed group in the case of excessive drinking and smoking. Lack of sleep time was also the highest risk among graduate students. Recently, the risk ratio of youth (born 1997-99) cohort to unhealthy behavior that changes from teenager to adults has increased compared to past youth (born 91-93). Conclusion: While the overall health behavior of adults in Korea has improved, it has been confirmed that the youth does not. It is necessary to continuously monitor the health behavior of youth in the future, and diversify health measures by classifying them into groups rather than single health measures for youth.

Objectives: Considering the limited resources, identification of the factors affecting length of stay (LOS) is of great value to determine the efficiency and optimal use of hospital resources. This study aimed to identify the LOS and the factors affecting the LOS for patients with ischemic heart disease. Methods: The Korean National Hospital Discharge In-depth Injury Survey Data (2017) collected by the Korea Centers for Disease Control and Prevention were used. We extracted 5,845 inpatients who principal diagnosis is ischemic heart disease. The factors affecting the LOS were identified through multiple regression analyses based on demographic, medical use, and disease characteristics. Results: The mean of the LOS was 4.27 days (standard deviation=7.97). The LOS was longer in women, elderly people, and medical aids recipients. Also, the results showed that the LOS has a significant relationship with the variables of type of admission (emergency), hospital residence (Seoul & metropolitan city), the number of beds (100 to 499 beds), surgery status (patients who underwent coronary procedure including coronary artery bypass grafting), the CCI severity and Primary diagnosis (acute myocardial infarction). Conclusions: This study found determinants of LOS for patients with ischemic heart disease include demographic, medical use, and disease characteristics. The identification of such factors could assist in optimizing patient LOS.

Objectives: Several panel surveys have recently been accumulated for various purposes in Korea, and vast amounts of data have been built over a long period of time. However, there are still no networks or platforms that can provide integrated information about existing panel data. In this paper, panel data, which is widely used on healthcare research, was reviewed and future suggestions were proposed in establishing panel data. Methods: This study classified and analyzed 9 types of panel data commonly used in healthcare research according to their status, sample composition, sample retention rate, survey items, and other characteristics. Results: The use of panel data is particularly useful for longitudinal analyses, such as examining health trajectories or identifying causal relationships with influencing factors. To utilize panel data effectively for healthcare research, efforts are needed to establish links between panel data and administrative data, provide post-survey management support, and ensure continuous quality improvement. Conclusions: It is very important to establish the integration platform for various panel data and administration data. If we develop strategies for quality management for it, the value of panel data and utilization of researchers will be enhanced.

Purpose : The aim of this study was to identify the impact of age and factors on mortality of patients with community-acquired pneumonia in south korea. Method : The study subjects were 11,076 patients aged 18 years and older that admission for communityacquired pneumonia(CAP). The data were obtained from Korean National Hospital Discharge In-depth Injury Survey in the 2008, 2013 and 2017. Logistic regression models were used to explore the impact of age on mortality of patients with CAP. Result : The most influential factors of the mortality among pneumonia patients were age, emergency patients, and severity. The mortality risk of CAP increased significantly in from 2008(p<0.001) to 2017 (p<0.001). The highest risk of mortality was patients of over 80 years and the mortality risk of patients over 80 years was higher in 2017 (OR=15.92, 95% CI 6.39-39.66%) than in 2013(OR=10.04, 95% CI 4.01~25.14). The medical institutions characteristics was high the emergency room(OR=3.18, 95% CI 2.37~4.27), and the mortality risk was high for patients with length of stay 1-4 days in the medical use characteristics. Conclusion : Age is a strong factor on mortality of patients with CAP. We recommend the use of severity marker that specifically reflect the age factors, and specific discussions are required for the implementation of the appropriateness evaluation considering age factors.

Purposes: The aim of this study is to evaluate whether the contents of hospital reservation and reception applications(apps) are qualitatively useful in meeting the needs of medical consumers and improving hospital accessibility and convenience. Methodology: (1) identify consumer needs through social data web mining, (2) describe the status of key contents of mobile apps to improve accessibility and convenience of care, and (3) verify the quality of apps through validated tools Finding: The contents of ‘mobile reservation function’ and ‘waiting time information provision’ that can contribute to reduction of delay time of care and efficiency of desk work were supported, but the level of utilization was insufficient. The quality level of the app, including the level of consumers' needs, has shown a wide gap between the apps. Implications: The recent development of mobile apps for hospital accessibility and consumer needs has shown a wide gap in the quality of apps, including information and aesthetic. Therefore, it is necessary to develop apps based on user interface(UI), user experience(UX) based designs that can promote the usefulness and convenience of apps while monitoring needs of consumers continuously

스마트센서스의 가능성 모색

국가 운영의 기본 자료로 쓰이는 센서스는 최근 개인정보보호에 대한 관심 고조, 방문조사의 불편함, 조사 예산 증가 등의 이유 등으로 조사에 어려움을 겪고 있다. 이에 우리나라를 비롯한 많은 나라들이 기존의 조사 센서스를 등록 센서스로 대체하고 있는 추세이다. 우리나라는 최근 젊은 인구가 부모로부터 독립하여 사는 경우가 많고, 그 경우 주민등록주소와 실제 거주 주소가 상이할 수 있기 때문에 실제 거주지 파악에 어려움을 겪을 수 있다. 본 연구는 스마트폰의 위치센서 정보를 이용하여 사용자들의 실제 거주지를 파악할 수 있는 방법을 제시하고, 이를 경험적인 자료를 토대로 검증하고자 하였다. 이를 위해 스마트폰 사용자의 일주일간 위치 정보를 이용하여 가장 밀도가 높은 중심점을 구하고 이를 사용자의 실제 거주지와 비교하였다. 그 결과, 주소확인이 가능한 참여자의 93.7%가 밀도함수 90%내에 포함되어 있는 것을 확인할 수 있었다. 비록 탐색적인 수준이지만 스마트폰만을 활용하여 센서스에서 가장 중요한 요소라 할 수 있는 사용자의 거주지를 파악할 수 있는 방법을 제시했다는 점에서 본 연구의 인구학적 및 정책적인 의의를 찾을 수 있다. The growth of smartphone penetration rate in South Korea is outstanding. We pay attention to three facts associated with smartphone: (1) most people have smartphones, (2) most users carry and use smartphones in every second, and (3) all smartphones are equipped with geographic sensors that imply an important demographic meaning. The current study aims (1) to examine if one’s usual locations (residence) can be detected by the GPS or WPS data monitored by and compiled through one’s own smartphone, and (2) to evaluate the results to see how accurately and effectively smartphone can function as a census taker. We collected geographic sensor monitored data (GPS and WPS) from 287 Seoul residents aged 20 to 49 who use smartphones daily. The current study showed a possibility that geographic raw data monitored by smartphones sensors can be converted into a value-added piece of information that can detect the location of user’s home. We believe that the current exploratory study on ‘Smart Census’ can suggest at least one direction where census-related environment would move with wide spread use of smartphone and its technological innovation.
