Healthcare services can be provided through a number of independent service platforms for measurement of vital signs, diagnosis and prevention of diseases, and Information and communication technology(ICT) such as internet and mobile are converged to provide health information to users at anytime and anywhere, and it is in the center of the IoT(Internet of things). Accordingly, in this paper, we designed IoT based urination management system and evaluate the performance. A low - power Zigbee network was constructed for the configuration of the urination management system. The implemented capacitive diaper sensor was operable for the duration of 2,000 hours. We also built a database server using Raspberry Pi, a tiny embedded device, and stored the collected data to verify the data through an Android-based mobile application. The proposed urination management system can be utilized not only for the older patients, but also for the infants.

The aim of this study is to analyze the meaning of Korean elders' reminiscences by analysing korean novel literature from 1930s to 1990s. The results of this study are as follows : The moaning of elders' reminiscences are the reflecting on their life, conquesting the excessive fondness the regrecting, the pursuiting of the powers, the pursuiting of the love(Jeong) and the conformation of their exsistence. Elders have tried to examine their life through reflection on their life tha? they did not live good life as son and daughter for parents and as parents for children and that they have foolishly lived, on dream that they did not come true, on their learning that they did not unsatisfied. But elders conquest the excessive fondness. They have felt their limitations of power in the conflict of human relation, the economic matter and the difficult predicament, and have finally accepted their life as it is by conquesting from their tenacity. It is dynamically found that both the reflecting on their life and conquesting of the excessive fondness. And they pursuit the powers. It means the pursuit of the vital powers, the vigorous powers and the competency, Elders have pursuited their vitality, vigor and competency through their reminiscences and have wanted to be recognized by others as a powerful being. These have dynamic and compounded aspects. Elders have pursuited the purely love (Jeong) through their reminiscence togather with their sisters and brothers. And the confirmation of their exsistence refer to through their own situation of health, condition, children, neighbourhood and doing their duty as a human. Elders have confirmed the present value of their being through the reflecting the present, past self, other men around themselves, children, neighborhood and the doing their human duty as a good men. Therefore the results of this study can offer new view on the elders' reminiscences that we have to understand them as a process as what they are, escaping from the simple logic that elders' reminiscence have a positive or a negative effects. Also, this study which have examined the natures of Korean elders' reminiscences can cast a new light on elders' nursing proper for Korean culture.

This study is on Yoshimasu Todo's thoughts of a real doctor and medicine. Conclusions are as below. disease-doctor[疾醫] is a doctor treating diseases by poisonous medicines. His role is different from food-doctor[食醫] who recuperates vital energy by food. Unlike food-doctor, a disease-doctor only detoxicates poisons of diseases by using poisonous medicines. Disease-doctor shall not take credit upon himself for the service of Heaven' s power. This is Yoshimasu Todo's view of a real doctor. Medicine is not an imagination, but a reality. It is the recognition of knowing what can be known and seeing what can be seen The truth of medicine is in ancient words(古語), ancient teachings[古訓] and ancient ways[古法]. To study medicine is not recklessly believing and following the contents of ancient medical texts-${\ulcorner}$Sanghanlon(傷寒論)${\lrcorner}$, ${\ulcorner}$Geumgwe-yolyag(金置要略)${\lrcorner}$,${\ulcorner}$Somun(素問)${\lrcorner}$, ${\ulcorner}$Yeongchu(靈樞)${\lrcorner}$. It is to follow the ancient ways written and left in ancient books and not to follow wrong ways fabricated by after ages. The theories of eum-yang-obaeng(陰陽五行) and o-un-yuggi(五運六氣) are useless to medicine because these are groudless ones. This is Yoshimasu Todo's view of medicine.

Background: To evaluate the effect of thoracic mobility exercise and deep breathing exercise applied to stroke patients on pulmonary function. Methods: The subjects were divided into two group. Twenty-five patients with stroke were randomly assigned to DB (deep breathing exercise) group (n=13) and TM (combination of deep breathing exercise and thoracic mobility exercise) group (n=12). During four weeks, DB group were carried out deep breathing exercises for 5~10 minutes twice a day and TM Group were carried out deep breathing exercises for 5~10 minutes and thoracic mobility exercise for 20~30 minutes twice a day. All tests were completed before and after experiment. The pulmonary functions were measured by PowerBreathe K5 (Hab International Ltd, England) and tape measure respectively. For each case, the experimental data were obtained in 4 items; average of inspiratory load, inspiratory flow speed, inspiratory flow volume and chest expansion. Results: The results of this study were as follows: 1. In DB group, the statistically significants were shown on average of inspiratory flow speed, inspiratory flow volume and chest expansion (p<.05). 2. In TM group, the statistically significants were shown on all items (p<.05). 3. There was a statistically significant difference on all items between DB group and TM group (p<.05). Conclusions: The above results revealed that DB and TM group can be used to improve pulmonary function in stroke patients. In comparison of DB and TM group, TM group was more improved.

Body area networks (BANs) have emerged as an enabling technique for e-healthcare systems, which can be used to continuously and remotely monitor patients' health. In BANs, the data of a patient's vital body functions and movements can be collected by small wearable or implantable sensors and sent using shortrange wireless communication techniques. Due to the shared wireless medium between the sensors in BANs, it may be possible to have malicious attacks on e-healthcare systems. The security and privacy issues of BANs are becoming more and more important. To provide secure and correct association of a group of sensors with a patient and satisfy the requirements of data confidentiality and integrity in BANs, we propose a novel enhanced secure sensor association and key management protocol based on elliptic curve cryptography and hash chains. The authentication procedure and group key generation are very simple and efficient. Therefore, our protocol can be easily implemented in the power and resource constrained sensor nodes in BANs. From a comparison of results, furthermore, we can conclude that the proposed protocol dramatically reduces the computation and communication cost for the authentication and key derivation compared with previous protocols. We believe that our protocol is attractive in the application of BANs.

Cultural heritage means a great lot to a nation's social system and its people's behavior consciousness and plays an important role in its self-development and improvement. It is essential for a nation's self-education and renewal. Improper cultural heritage will be disastrous because it may fall a nation into a loss of terrible chaos. Only the proper cultural heritage can make it always self-awaking, self-correcting and remaining vital in life. This paper, from the perspective of Choi Bu's Pyohaerok, makes a thorough analysis of the unbalance heritage of Chinese ancient culture for thousands of years. For example, many fine traditions gradually vanished in our actual life or only take half their life in heritage nowadays, such as our ancient broad and profound Confucian etiquette, ancient exquisite brocade art and architecture, ancient advanced ship-building technology and many other advanced numerous technological inventions; however, too much unwanted cultural rubbish keeps constant prevailing and takes repeated successions in the life, such as the heavy-form-and-light-content management mode, borrowing power to do evil, neglecting technological inventions long time and generally believing in ghost theory,etc.. This paper mainly focuses on the partial successions of the bad cultural heritage and its bad influence on the country, and concludes that it is just that that makes the country more and more backward. Therefore, the paper makes some pondering over these issues and proposes some related ideas of country-building to attract others participation to deal with them.

Recently, wireless body area network (WBAN) has received much attention as an application for the ubiquitous healthcare system. In WBAN, each sensor nodes and a personal base station such as PDA have an energy constraint and computation overhead should be minimized due to node's limited computing power and memory constraint. The reliable data transmission also must be guaranteed because it handles vital signals. In this paper, we propose a systematic network coding scheme for WBAN to reduce the network coding overhead as well as total energy consumption for completion the transmission. We model the proposed scheme using Markov chain. To minimize the total energy consumption for completing the data transmission, we made the problem as a minimization problem and find an optimal solution. Our simulation result shows that large amount of energy reduction is achieved by proposed systematic network coding. Also, the proposed scheme reduces the computational overhead of network coding imposed on each node by simplify the decoding process.

In recent times, gas insulated medium voltage (MV) circuit breakers (CB) form a vital component in power system network, considering its advantages such as reduced size and safety margins. Gas insulation characteristics of circuit breakers are generally measured by lightning impulse (LI) test according to IEC standard 60060-1 as a factory routine test. Considering the environmental issues of $SF_6$ gas, many research works are being carried out towards the mixture of $SF_6$ gases for high voltage insulation applications. However, few reports are only available regarding the LI withstand and streamer propagation characteristics (at both positive and negative polarity of waveform) of $SF_6/N_2$ gas mixture insulated medium voltage circuit breakers. In this paper, positive and negative polarity LI tests are carried out on 22 kV medium voltage circuit breaker filled with $SF_6/N_2$ gas mixture at different gas pressures (1-5 bar) and at different gas mixture ratios. Important LI parameters such as breakdown voltage, streamer velocity, time to breakdown and acceleration voltage are evaluated with IEC standard LI ($1.2/50{\mu}s$) waveform. Weibull distribution analysis of LI breakdown voltage data is carried out and 50% probability breakdown voltage, scale parameter and shape parameter are evaluated. Results illustrate that the $25%SF_6+75%N_2$ gas filled insulation considerably enhances the LI withstand and breakdown strength of MV circuit breakers. LI breakdown voltage of circuit breaker under negative polarity shows higher value when compared with positive polarity. Results show that maintaining the gas pressure at 0.3 MPa (3 bar) with 10% $SF_6$ gas mixed with 90% $N_2$ will give optimum lighting impulse withstand performance of 22 kV MV circuit breaker.
