The WBAN(Wireless Body Area Network) technology is a short distance wireless network which provides each device's interactive communication by connecting devices inside and outside of body located within 3 meters. Standardization on the physical layer, data link layer, network layer and application layer is in progress by IEEE 802.15.6 TG BAN. The The WBAN servides consists of both medical and non-medical applications. The medical application service uses the sensor that transfer the periodic traffic and have different data rates. It uses GTS method to guarantee QoS. In this paper, a new method is proposed, which are suitable design for MAC Protocol. Firstly, MAC frame structure and a primitive based on the WBAN are proposed. Secondly, we proposed the GTS algorithm improved the channel utilization based on the WFQ(Weighted Fair Queuing). The proposed scheduling method is improved channel utilization compared with i-Game(Round Robin scheduling method).

We predict the mortality of the elderly patients visiting the emergency department who are over 65 years old using Feed Forward Neural Network (FFNN) and Convolutional Neural Network (CNN) respectively. Medical data consist of 99 features including basic information such as sex, age, temperature, and heart rate as well as past history, various blood tests and culture tests, and etc. Among these, we used random forest to select features by measuring the importance of features in the prediction of mortality. As a result, using the top 80 features with high importance is best in the mortality prediction. The performance of the FFNN and CNN is compared by using the selected features for training each neural network. To train CNN with images, we convert medical data to fixed size images. We acquire better results with CNN than with FFNN. With CNN for mortality prediction, F1 score and the AUC for test data are 56.9 and 92.1 respectively.

The purpose of this study was to identify the differences in medical care utilization by regional economic status using the National Hospital Discharge Patients Injury Survey. In order to determine economic status of each region, 234 cities and counties were categorized 5 quintiles according to their financial self-reliance ratio. The main results are as follows. First, low economic region has high age-standardized admission rate and standardized mortality rate. Second, of 16 major diseases, cerebrovascular and heart diseases, lung cancer, and stomach cancer reported greater changes in standardized mortality rate by regional economic status. Third, the rate of admission via emergency room in low economic region is higher than that of high economic region. Lastly, in the major illnesses, lower economic status led to an increase in average length of stay. Therefore, In order to bridge the gap in health inequality across regions, a regional medical policy tailored for each region and characteristics of the economic status should be established.

Purpose: This study aimed to evaluate the current status of hospice palliative care facilities in Korea. Based on the result, we attempted to suggest activation plans of hospice palliative in Korea. Methods: To conduct a survey, we obtained a list of hospice palliative care facilities from related agencies and academic societies. A survey was conducted from February, 2009 to March, 2009. The survey was consisted of general characteristics of organizations, manpower, facilities & equipments, and so on. In addition, we used data from Statistics Korea to estimate the number of beds required and the bed occupancy rate. Results: Total number of facilities responded to the questionnaire were 53. Forty-two facilities were general hospitals and 6 facilities were clinics among the total 53 facilities, and 18.8% of facilities were located in Seoul, Incheon and Gyeonggido. Overall bed occupancy rate was rather low as 21.9%, and there were 4 provinces where bed occupancy rates were 0%. Deaths in hospice palliative care facilities during 2008 were 6.3% of total deaths from cancers. As for the questions about the financial status of facilities, 86% of facilities were answered financial insufficiency. Also more than half of the facilities gave financial insufficiency as the reason for shortage of human resource supplies and inability to achieve the standard for authorization by the government. Facilities answered in order to activate the hospice palliative care, governmental support is needed, mostly in financial support (71.2%), donation tax deduction (43.1%), and setting up a public utility foundation (23.5%). Conclusion: This study showed low rates of hospice palliative care use and bed occupancy in Korea. Regional variance in bed occupancy rate was significantly high. As a roadblock for these problems, most of the facilities cited financial insufficiency. Therefore, there must be some action plans to boost financial support to activate hospice palliative care in Korea. Finally, efforts to improve these circumstances including lack of understanding about hospice and palliative care, are needed as well.

This study investigated the awareness and purchase status of the private dental insurance. Self-reported survey was conducted with patients over the age of twenties who visited dental institutions located in Seoul Metropolitan City and Gyeonggi Province. The demographic and health related characteristics of respondents were analyzed, and logistic regression was conducted to examine factors affecting the awareness and purchase of private dental insurance. Because only four years had been passed since the introduction of private dental insurance, the awareness and purchase rate was found to be low. However, the number of people considering subscription due to the economic burden of dental care service was relatively high. Factors affecting awareness were satisfaction of the national health insurance, purchase of private health insurance and private dental insurance, self-perceived dental health status, and smoking. The variables affecting purchase of dental insurance were age, awareness, purchase of private health insurance, smoking, number of visits to dental institution. Because qualitative and quantitative change would be made in the dental care utilization due to the rapidly growing dental insurance subscribers, further studies regarding the trend of purchase rate of private dental insurance and the effect of dental insurance on use of dental institution are needed.

Purposes: 우리나라 공공의료기관들의 경영실적 보고에 따르면 대부분의 공공의료기관들이 만성적자로 인한 경영난 문제를 겪고 있는 실정이다. 이는 공공의료서비스 제공 등이 주요 원인이겠지만 그럼에도 공공의료기관들의 경영효율화 문제는 지속적으로 지적되고 있음은 공공연한 사실이다. 이에 본 연구는 고정비 성격이 강한 인적자원관리비용과 경영성과 간의 관계를 분석하여 공공의료기관의 경영성과 개선을 위한 경영적 함의를 제공하고자 하였다. Methodology: 분석자료는 2014년부터 2019년까지 39개 지역거점 공공병원의 재무자료를 이용하였고, STATA SE 12.0을 사용하여 다중회귀분석과 패널회귀분석을 실시하였다. Findings: 다중회귀분석을 통한 단면연구 결과에서는 인건비가 높을수록 경영성과가 높은 경향을(2014년 의료수익:1.523/ 2015년 의료수익: 2.002, 의료수익의료이익률: 0.002/ 2016년 의료수익: 1.223) 보였으나 패널회귀분석을 통한 종단연구 결과에서는 복리후생비가 높을수록 경영성과가 의미있게 높은 경향을(의료수익: 3.232582/ 의료수익의료이익률: 0.0014502) 보였다. 이는 인건비는 경영성과에 단기적인 효과가 있는 반면 복리후생비는 경영성과에 장기적인 효과가 있음을 반영하는 것이라고 볼 수 있다. Practical Implication: 본 연구는 이러한 결과를 기반으로 장기적인 효과가 있는 복리후생비의 중요성을 제시하고, 공공의료기관의 경영성과에 영향을 미치는 인건비와 복리후생비의 특성 파악을 통하여 효과적인 인적자원관리방법을 위한 경영적 함의를 도출하였다는 점에서 의의가 있겠다.
