This paper describes the development of a wearable robot to assist ankle power for the elderly. Previously developed wearable robots have generally used motors and gears to assist muscle power during walking. However, the combination of motor and reduction gear is heavy and has limitations on the simultaneous control of stiffness and torque due to the friction of the gear reducer unlike human muscles. Therefore, in this study, Mckibben pneumatic muscle, which is lighter, safer, and more powerful than an electric motor with gear, was used to assist ankle joint. Antagonistic actuation using a pair of pneumatic muscles assisted the power of the soleus muscles and tibialis anterior muscles used for the pitching motion of the ankle joint, and the model parameters of the antagonistic actuator were experimentally derived using a muscle test platform. To recognize the wearer's walking intention, foot load and ankle torque were calculated by measuring the pressure and the center of pressure of the foot using force and linear displacement sensors, and the stiffness and the torque of the pneumatic muscle joint were then controlled by the calculated ankle torque and foot load. Finally, the performance of the developed ankle power assistive robot was experimentally verified by measuring EMG signals during walking experiments on a treadmill.

Purpose: It has been attempted to support mother of premature infants by providing information of premature infant care using e-Learning because premature infants need continuous care from birth to after discharge. Method: The e-Learning Program for mother of premature was developed with Xpert, Namo web editor, Adobe Photoshop, and PowerPoint and applied for 4 weeks from 4 to 30 September 2006. Result: 1) We found that the contents of information which premature infants' need when being in the hospital and after discharge were the definition of a premature infant, orientation of NICU, care of premature infants, care of premature infants' common diseases, the connection of healthcare resources, exchange of information, and the management of rearing stress. 2) The program content consisted of cause of premature birth, comparison to full-term baby, physiology character, orientation of NICU, common health problems, follow up care, infection control, feeding, normal development physically and mentally, weaning method, and vaccination. Conclusion: Considering the results, this program for mother of premature is a useful means to provide premature-care information to mothers. This information can be readily accessible and can be varied and complex enough to be able to help mothers to the information and assistance they require.

In this paper, a new automatic classification method for the normal EEC and schizophrenia EEC using hidden Markov model(HMM) is proposed. We used the feature parameters which are the variance for statistical stationary interval of the EEC and power spectrum ratio of the alpha, beta, and theta wave. The results were shown that high classification accuracy of 90.9％ in the case of normal person, and 90.5％ in the case of schizophrenia patient. It seems that proposed classification system is more efficient than the system using complicate signal processing process. Hence, the proposed method can be used at analysis and classification for complicated biosignal such as EEC and is expected to give considerable assistance to clinical diagnosis.

In this paper, we assume that sensor nodes organize the multi-hop networks, are fixed, and operate as full function devices(FFD). The wireless sensor network(WSN) only consists of mobile nodes without the assistance from the fixed infrastructure, which increases the flexibility of the network. However, it is difficult to perform routing in the WSN, since sensor nodes freely join in and drop out of the network, and some sensor nodes have very low power. We propose the algorithm combining routing schemes based on the bitmap and cluster methods in this paper. Through computer simulations, we show the validity of the proposed algorithm.

Interim measures by an arbitral tribunal aim to protect the parties' rights before or during arbitral proceedings for avoiding frustration of the final award in international commercial disputes. Even though decisions of the interim measure are expected to be performed by parties directly during the arbitral processing, it is not easy to be provided by the arbitral tribunals cause of lack the power to enforce their decisions directly against the parties. Particular court supports mechanism for enforcement directly to assistance to arbitral tribunal's decisions. Decisions on interim measures are provisional. Even though the arbitration is ongoing to request interim measure directly to the arbitral tribunal, relevant courts are able to ensure effective relief cause by the difficulty of limited rights of the arbitral tribunal. In this time both revised Korean Arbitration Act in 2016 and UNCITRAL 2006 revised Model Law are complemented to attach articles for recognition and enforcement of interim measures by arbitral tribunal during the arbitration processing. It could be possible to enforcement of decisions of interim measures by arbitral tribunal on the revised arbitration law. In this paper it is considered the problems and alternatives on related applicable articles and articles of recognition and enforcement for the interim measures by arbitral tribunal under the revised UNCITRAL Model law and Korean Arbitration Act.

The study aims to analyze the adaptation strategies and resilience of tobacco farmers to face unfavorable trading system. The research method refers to a qualitative approach with phenomenological models and case studies. The findings revealed tobacco farmers in Jember developed various adaptation strategies and resilience through farmer group organizations, partnerships, self-capacity building and access to financial institutions based on economic, social, cultural, and experience values from various sources and interactions among fellow tobacco farmers. The tobacco trading system, which is left to the market mechanism, results in low bargaining power of farmers, this encourages tobacco farmers to develop various adaptation and survival strategies, namely through collective activities of farmer groups, partnerships and self-development and access to financial institutions. Dealing with the unfavorable tobacco trading system, tobacco farmers do not switch to other commodity farming but adapt and make Jember a center for tobacco production in East Java and Indonesia. From this findings, it suggests to the government as the regulator does not only provide subsidies for tobacco farmers, but also must provide various technical assistance to increase the ability of tobacco farmers. More importantly, regulations must be made benefit tobacco farmers other than corporations so that equality can be enjoyed by tobacco economy players.

Recently, Vertical-Closed Loop system using geothermal which is the most efficient among the building cooling and heating systems is coming into wide spread due to assistance of domestic policies. However, there is a limitation that a design of ground heat exchanger taking 60% of construction cost is done by GLD and GLHEPRO programs without specific guidelines and consideration on Entering Water Temperature(EWT). For getting an optimal EWT, we analyzed the costs for construction of ground heat exchanger and cooling and heating for 15 years. In the results, reduction of construction costs as the length of ground heat exchanger shortens was much greater than increase of the electrical power consumption as COP gets low. EWT that COP of heat pump can be 3.76 or above was below $31^{\circ}C$ in cooling and was over $5^{\circ}C$ in heating.

Purpose - Korean traditional markets are falling behind the times, because they have not met the demands of social changes including: an overall improvement in standards of living, shift in purchasing form and propagation of cars. It is one of the most indigenous and conventional foods of Korea, taking a seat far in the corner of Korean traditional culture. Research design / data / methodology - Korean traditional rice cakes however have their limits. They are produced and sold by independent shop owners who cannot compete with the brand power of franchise organizations. The leadership of adminstration is needed for these shop owners particularly in visual merchandising related to interior design and display. Results - Additionally, the advent of major company-run rice cake cafe adds fresh fuel to the problem in addition to small but luxurious packaging. Small business owners need packaging technology for overall quality improvement of sales of rice cakes. Additional help is needed with the mode of packing to promote sales and win consumer confidence. Conclusions - Further assistance with marketing for seasonal displays is needed as well as teaching business owners how to read graphic data. Regular specialized education for visual merchandising of rice cakes could help independent market owners win the competition against franchise-based organizations.

Nowadays most of scholarship is based on the western model. Traditional Chinese Medical education system also follows the western medical education. In the views of medical sociology, it shows very interesting phenomenon that the modernization of traditional area follows the western model of modernization. Moreover, it provides a good chance to discuss whether modernization and westernization of tradition is real development or not. Traditional Chinese Medicine had been the only institutional medicine in China for a long time. But the status of Traditional Chinese Medicine has been changed very rapidly since modern era. Shanghai Traditional Chinese Medical School was established in 1916. But National Party government tried to abolish Traditional Chinese Medicine and it met a crisis of maintenance. But the situation has been dramatically changed when Communist Party got the power in 1949. The Communist Government needed a chief medical service. And Traditional Chinese Medicine could meet the condition. Traditional Chinese Medicine could provide also the ideology of national superiority. Therefore, Traditional Chinese Medicine has been protected and developed by the assistance of the Communist Party. In the process, Traditional Chinese Medical education has been professionalized.

Solvolysis of tert-butyl halides and 1-adamantyl tosylate in methanol-acetone mixtures and solvolysis of tert-butyl bromide in methanol-chloroform mixtures have been studied. Solvent ionizing power of methanol-acetone mixtures were calculated by the Grunwald-Winstein equation and discussed the Y value variation caused by substrate changes. Y values based on 1-adamantyl tosylate is superion to others since it varies in wide range for methanol-acetone mixtures. It was found that the order of electrophilic assistance to leaving group is OTs > Cl > Br > I.
