The sensor network for the health care application service has the man or movable object as the main sensing object. In order to support inter-node interaction by the movement of such sensing objects, the node's dynamic function modification, dynamic self-configuration and energy efficiency must be considered. In this paper, the Agilla model which supports the dynamic function modification through the agent migration between nodes and LEACH protocol which guarantees the dynamic self-configuration and energy efficiency through the configuration of inter-node hierarchical cluster configuration are analyzed. Based on the results of the analysis, the Mobility Agent Middleware which supports the dynamic function modification between nodes is designed, and LEACH_Mobile protocol which guarantees the node nobility as the weakness of the existing LEACH protocol is suggested. Also, the routing module which supports the LEACH_Mobile protocol is designed and the interface for conjunction with Mobility Agent Middleware is designed. Then, it is definitely increase performance which un mobility node of transfer data rate through LEACH_Mobile protocol of simulation result.

As the number of Coronavirus Disease-19 (COVID-19) patients increases in a global pandemic situation, the usefulness of mobile computed tomography (CT) is gaining attention. Currently, mobile CT follows the basic safety and essential performance evaluation criteria of whole-body or limited-view X-ray CT in order to obtain device approval and evaluation in the Republic of Korea. Unlike stationary CT, mobile CT is not operated in shielded areas but rather areas such as intensive care units, operating rooms, or isolation rooms. Therefore, it requires a different basic safety and essential performance evaluation standard than stationary CT. In this study, four derived basic safety evaluation criteria related to electrical, mechanical, and radiation safety were included (dose indication test, protection against stray radiation, safety measures against excessive X-rays, half-value layer measurement); and seven essential performance evaluation criteria were included (tube voltage accuracy, mAs accuracy, radiation dose reproducibility, CT number of water, noise, uniformity, and spatial resolution); total eleven basic safety and essential performance evaluation criteria were selected. This study aims to establish appropriate basic safety and essential performance evaluation criteria for simultaneously obtaining images with diagnostic value and reducing the exposure of nearby patients, medical staff, and radiologic technologists during the use of mobile CT.

This study discusses the development of a u-Health care system that can detect quickly and cope actively with emergent situations of chronic disease patients who lead everyday life. If a patient's emergent situation is detected by personal health care host(PHCH), which is composed of acceleration and vibration sensors, GPS, and CDMA communication module, a text message on the patient's current location is transmitted to the hospital and the guardian's mobile terminal so that they can cope with the situation immediately. Especially, the system analyzes data from sensors by using neural network and determines emergent situations such as syncope and convulsion promptly. The exact location of patients can also be found in the electronic map by using GPS information. The experiments show that this system is very effective to find emergencies promptly for chronic disease patients who cannot take care of themselves and it is expected to save many lives.

Purpose: To examine effects of a postnatal care program on self-efficacy, self-management, and glycemic control in women with gestational diabetes mellitus (GDM). Methods: A non-equivalent control group non-synchronized quasi-experimental design was used. Sixty-two women with GDM were enrolled and assigned to either an experimental group (n=30) or a control group (n=32). The experimental group received an intervention which was postnatal care program for women with GDM. The postnatal care program for GDM included an individual education with leaflet and mobile web-based video with three times of telephone counseling. Effects of the intervention were measured with self-efficacy, self-management questionnaire, and a 75 g oral glucose tolerance test (75g OGTT). Statistical significance was examined using independent t-test and $x^2-test$. Results: Although there was no significant difference in 75g OGTT ($x^2=.11$, p=.748) or self-management (t=-1.28, p=.206), there was a statistically significant increase in self-efficacy (t=-2.02, p=.048) in the experimental group compared to that in the control group. Conclusion: A postnatal care program is needed for women with GDM to improve their self-efficacy. Further studies are warranted to improve self-management and glycemic control through tailored education for GDM postpartum women.

The emergence of new diseases such as the Covid 19 pandemic that occurs in the 21st century and the occurrence of health abnormalities according to the busy daily life of modern people are increasing. Accordingly, the importance of health care management and data-based health management is being highlighted, and in particular, interest in personal health management data based on personal health care data of patients is rapidly increasing. In this study, to solve the difficult problems of personal health management, we developed a personal health care platform incorporating IT for self-diagnosis and solution and developed an application that measures bio-signals generated in the human body and transmits them to the platform. A health management system was established. Through this, not only the health care of modern people, but also the psychological and emotional care support needs through psychological and emotional monitoring of the developmentally disabled and the vulnerable who have difficulty in expressing their opinions are to be addressed. In addition, the overall health and living environment data of the individual was integrated to develop an optimized medical and health management service for the individual.

Mobile devices such as smart phones have brought big changes to be called as 'mobile big bang' against which we can't go. Mobile banking service and MTS(Mobile Trading System) are freely available at any time, anywhere and we are able to activate communications between financial company staffs out of the office and take care of business works even remotely by using mobile devices. Mobile devices are approaching as 'smart mobile innovation' to improve an enterprise productivity and competitiveness, but threats which engaged in unfair trading behaviors or unwholesome business works in finance companies are increasing and the customer's information can be leaked out by using the nonpublic official information and mobile devices. Therefore, we have to analyze the potential problems and take the necessary countermeasures with preemptive steps to protect the customer's information and improve the financial trading soundness and fairness. In this paper, we would like to suggest countermeasures and threats against using the financial company's mobile devices focusing on the financial investment companies by 'Capital Market and Financial Investment Business Act'.

Designing the User-Based Voluntary Service Recommendation Program proposed in this study was motivated by the fact that it is not easy for volunteers to find a place for their services. Even though there are many volunteer centers or organizations, volunteers often experience difficulty in where and how they should apply for their work as those places are not well promoted. Thus, this program has been designed by applying the mobile push services along with location technology. The authors plan to introduce the program to the public as an open source by implementing the program with both Android and Python - hoping that the program will be useful to the users and volunteer organizations.

이동 컴퓨팅 환경에서는 이동 노드의 위치를 신속하게 탐색하고 지속적인 네트워크연결을 통하여 전송중인 패킷을 계속적으로 전달하는 것이 중요하다. 본 연구에서는 이동 노드(MN; Mobile Node)가 새로운 외부 에이전트(FA2; Foreign Agent 2)로 이동할 경우에 이동노드가 FAI 및 홈 에이전트(HA; Home Agent)에게 Care-of Address를 전송 후, FAI이 가까운 위치에 있는 경우에는 새로이 터널링을 하지 않고, FAI을 통하여 전송중이던 대응노드로부터 패킷을 전송받아 FA2로 보내도록 하였다. 따라서, 제안한 방식을 사용할 경우 터널링에 소요되는 시간을 감소시킬 수 있기 때문에 패킷의 전송 시간이 빨라지고, 네트워크에서 발생하는 지연을 감소시킬 수 있다.

IPv6 기반의 이동 노드는 이웃 발견 프로토콜과 주소 자동설정 기능을 이용하여 스스로 의탁 주소(Care-of-Address : 이하 COA)를 구성한다. 이 때, 이동 노드가 가까이 있는 여러 개의 라우터 경계 사이를 짧은 시간동안 자주 이동한다면 이동 노드는 자신의 COA를 구성하는 과정을 빈번하게 반복하면서 이동 노드의 과부하가 발생할 가능성이 크다. 본 논문에서는 이러한 잦은 이동을 하는 이동 노드의 주소 자동설정 기능으로 인한 노드의 과부하를 줄이고 COA를 구성하는 시간을 최소화하기 위해 이동 노드의 주변을 가상의 셀로 설정하고 주변 셀에 대한 라우터들의 prefix를 라벨화(labeling)하여 이동 노드의 여러 개의 인터페이스에 설정해 놓고 라벨의 확인만으로 COA를 선택하는 방법을 제안한다.
