In this paper, we propose IoT based smart CCTV security service to prevent crime in blind spot and prevent unexpected fire or danger. In the proposed method, a RC (Radio Control) car is made using Raspberry pie, and a camera and various modules are installed in an RC car. It was then implemented using Raspbian O / S, Apache Web Server, Shell script, Python, PHP, HTML, CSS, Javascript. The RC car provides a security service that informs the manager of the situation by judging the risk of the scene with modules such as video, voice and temperature. Experimental results show that the transmission time of video and audio information is less than 0.1 second. In addition, real-time status transmission was possible in AVG, emergency, and manual mode. It is expected that the proposed method will be applied to the development of smart city by applying it to unmanned vehicles, drones and the like.

The purpose of this study is to develop a healthcare service based on standard protocol and information communication technology for mother's sustainable postpartum care. The developed service was consisted of a client area where mothers measure, manage and transmit their vital signs using their own smartphone and personal health devices, and a server area that manages and shares with the received mother's vital signs and the results of examination results and personal health records. The client area collects vital signs through the IEEE 11073 Personal Health Device (PHD) using the m-health application of the previous study and Continua Health alliance certified personal health devices and transfers to Health Level Seven (HL7) V2.4, Continuity of Care Record (CCR) and Continuity of Care Document (CCD). The server area consists of a mobile web that manages and shares the HL7 Fast Healthcare Interoperability Resources (FHIR)-compliant personal health records to ensure interoperability of examination results, and a mobile web where the postpartum caregiver enters and manages the results of the mother's examination results and provides it to the mother. In this way, the healthcare service of this study securing continued exchanges between the mother and postpartum caregiver improves the quality of life of the mother not only to satisfy the needs of the mother who was discharged but also through self-management and postpartum. In the future, we will conduct a study applying mothers and postpartum caregiver after approval of a clinical trail at a university hospital to evaluate developed healthcare services.

In this paper we suggest the EEF technique to improve the performance of U-Health System. The idea of the EEF technique is that a sensor node sends only the abnormal data of patients to the base node. This technique reduces the amount of data transfer between a base node and sensor nodes, and so the power consumption of sensor nodes will be saved. And also the processing cost of base node will be reduced. In the suggested U-Health System based on EEF technique, electrocardiogram sensors and GPS sensors are used to send the electrocardiogram and position information of patients to a server. The server analyzes the health state of patients from base nodes and sends the information about the patients in the emergent state to the nearest hospital. Through the simulation, we have confirmed the suitability of EEF technique for U-Health System.

In recent years, medical procedures have become more complex, while financial pressures for shortened hospital stays and increased efficiency in patient care have increased. As a result, several shortcomings of present film-based systems for managing medical images have become apparent. Maintaining film space is labor intensive and consumes valuable space. Because only single copies of radiological examinations exist, they are prone to being lost or misplaced, thereby consuming additional valuable time and expense. In this paper, mini-PACS for image archiving, transmission, and viewing offers a solution to these problems. Proposed mini-PACS consists of mainly four parts such as web module, client-server module, internal module, acquisition module. In addition, mini-PACS system includes DICOM converter that non-DICOM file format converts standard file format. In client-server module case, proposed system is combined both SCU (service class user: client) part and SCP(service class provider: sewer)part therefore this system provides the high resolution image processing techniques based on windows platform. Because general PACS system is too expensive for medium and small hospitals to install and operate the full-PACS. Also, we constructed web module for database connection through the WWW.

Objects Internet-based healthcare services provide healthcare and healthcare services, including measurement of user's vital signs, diagnosis and prevention of diseases, through a variety of object internet devices. However, there is a problem that new security vulnerability can occur when inter-working with the security weakness of each element technology because the internet service based on the object Internet provides a service by integrating various element technologies. In this paper, we propose a user privacy protection model that can securely process user's healthcare information from a third party when delivering healthcare information of users using wearable equipment based on IoT in a mobile environment to a server. The proposed model provides attribute values for each healthcare sensor information so that the user can safely handle, store, and store the healthcare information, thereby managing the privacy of the user in a hierarchical manner. As a result of the performance evaluation, the throughput of IoT device is improved by 10.5% on average and the server overhead is 9.9% lower than that of the existing model.

As growing up of elderly population, the interesting on healthcare system in normal life using W is increasing. An integrated u-healthcare service architecture with IEEE 802.11 and IEEE 802.15.4 based sensor network and code divisi(m multiple access(CDMA) public mobile telecommunication networks was designed and developed. Sensor nodes with electrocardiogram(ECG), body core temperature sensors are attached on the patients' body. The healthcare parameters are transferred to web server via CDMA mobile network or through existed LAN network. The existed LAN network is suggested to be used for continuous monitoring of patient's health status in hospital while mobile networks can be used for general purpose at home or outdoor where infra networks unavailable. This system enable healthcare personal to be able to continuously access, review, monitor and transmit the patients information whereever they are, whenever they want. And immediately check their status by using cellular phone and obtain detail information by communication with medical information server through CDMA. By using this developed integrated u-healthcare service architecture, we can monitor patients' health status for 24 hours.

The objective of this study was to propse the way that could enlarge the course In life for the graduates of Department of Food and Nutrition in Junior College. This study was carried out through the analysis of statistical data and questionnaires gathered from professors of Department of Food and Nutrition in Junior College and from dieticians of industry, school and hospital. The results of this study could be summarized as follows. 1. The cultivation number of dieticians is too excessive in comparison with the need, and so It is necessary for the colleges to restrict the row establishment of Department of Food and Nutrition for a time, and for the government to tighten the employment system of dieticians. 2. The employment of dieticians will be extended to such fields as school, hospital public health center and counsel office of nutrition to act as a nutritional educator or a medical server in the future, and consequently the colleges which cultivate dieticians should improve the curriculum to agree with this. 3. It is necessary for the government to renovate the system of dietician arrangement to such a way as establishes a new rule in which additional dietician Should be employed In accordance with the feeding number in industry and hospital, as restricts the position-combine of a dietician with a cook in a large feeding institute, as gives the qualification of a nutritional instructor only to the diatician at public health center, as gives the qualification of a nutrition -teacher to the dieticians who completed the course of study for the teaching profession and then allows them to act as a nutrition-teacher in school. 4. The way to give a higher grade of educational opportunity should be given to the graduates of Department of Food and Nutrition in Junior College for the supplement of dietician's faculty.
