In this paper, we introduce a warning message providing methodology by considering the elderly's walking behavior in V2P(: Vehicle-to-Pedestrian) communication systems. Using the elderly's accident records in Kyounggi-do area from 2011 to 2014, the elderly's accident behaviors are analyzed by categorizing accidents as road type (single road/ crossing road), existence of traffic signal (with signal/ without signal), existence of crosswalk (crosswalk/ jaywalk), cause of accident (jaywalk/ signal violation/ carelessness accident/ Etc.). In addition, the elderly's behavior variable and vehicle speed are applied, then some threshold values are utilized in a warning message providing in conflict area. Finally, we propose a distance which can protect an accident depending on the elderly's walking speed, safety margin and vehicle speed. By applying the results of this research to the V2P/P2V communication based road safety message providing system with the elderly's walking behavior, it may be helpful to reduce accident rate of the elderly.

The combination of Congenital central hypoventilation syndrome with Hirschsprung's disease, also known as Haddad syndrome, belongs to the family of diseases now designated as Neurocristopathies. We have experienced a case of Haddad syndrome in a male infant who presented with repetitive abdominal distension, bilious vomiting, and sleep apnea. Following colon study and rectal biopsy disclosed the absence of the ganglion cell. And the infant could not be weaned from mechanical ventilation since birth because of the absence of effective, spontaneous respiration during sleep. As he was diagnosed as Haddad syndrome, tracheostomy and ileostomy were performed consecutively. At the age of 4 months, he was relatively healthy but remained ventilator-dependent. We report the first Korean case of Haddad syndrome with a brief review of the related literature.

This study analyzes the factors effecting on pedestrian crossing behavior in the unsignalized intersection. Pedestrian crossing behavior is the results of mental stress defined as a combination of environment perception, avoiding accidents, halting collision, and instant crossing decision. It is necessary to make walkable intersection in cities through relieving this stress influenced by personality, traffic condition, and roadway environment. The purpose of study is empirically to examine the crossing behavior such as crossing satisfaction, crossing trial frequency and waiting time based on various factors effecting on crossing intersection by video and questionnaire survey. The $x^2$-test is applied to analyze the characteristics of crossing trial frequency according to each factor. Also, the hazard rate model is established to find the factors effecting on waiting time for crossing. Finally, the direct and indirect effects on the pedestrian crossing satisfaction are presented as the results of LISREL.

One of the major issues in recent researches on wireless sensor networks is to reduce energy consumption of sensor nodes operating with limited battery power, in order to lengthen their lifespan. Among the researches, we are interested in the schemes in which a sensor node periodically turns on and off its radio and requires information on the time when its neighbors will wake up (or turn on). Clock synchronization is essential for wakeup scheduling in such schemes. This paper proposes three methods based on the asynchronous averaging algorithm for clock synchronization in sensor nodes which periodically wake up: (1) a fast clock synchronization method during an initial network construction period, (2) a periodic clock synchronization method for saving energy consumption, and (3) a decision method for switching the operation mode of sensor nodes between the two clock synchronization methods. Through simulation, we analyze maximum clock difference and the number of messages required for clock synchronization.

This article examines the types and cooking methods of Emandoo as recorded in 15 royal palace studies and 8 old literature texts of the Joseon dynasty (1392-1909). Early Joseon Dynasty kind of Emandoo one kind, two kinds of mid and late 15 kinds, a total of 18 paper was introduced. A Emandoo ingredient materials of a pheasant, chicken, beef, abalone, sea cucumber, etc. were used. Emandoo were able to see that the current 'mulmandu' form of life that icing on the water after the starch into a small thin sliced fish flesh. The size of a Emandoo made small clams. The use of 'Gocho (苦椒)' on Chojang(醋醬), starting with 'emandoo" of Muhsin jinchan Euigwe"(1848) Further study will be conducted on recipes and ingredients recorded in these Euigwe and old books in order to develop a standardized recipe to make Emandoo appealing to a global palate.

Since the military servants' rebellion, the society of the Goryeo(高麗) dynasty had been getting into crisis worse and worse until late in it. Late in the 14th century, the society was constantly meeting tension and chaos including decline of the Yuan(元) dynasty, sudden rise of the Ming(明) dynasty and etc. This study is aimed to investigate the idea of justice and theory of governing advocated by Yaeun Jeon Nok Saeng, who lived in such tensed and chaotic era. Under the circumstance that threatened the national power of the Goryeo dynasty in the era where the Yuan dynasty changed to Ming dynasty, his idea of justice was expressed as "Theory for Friendship with Ming and Against Yuan", which was proposed in the aspect of considering the safety and maintenance of the nation and getting back the original national power of a country Goryeo. He thought that you should not make your people bothered by or troubled in their works but you should make them concentrate on their jobs for living to govern them eased. He emphasized that you should focus on stability of people's welfare in gentle ways not bothering your people even a little bit because he thought that the situation of that era looked like a thread bobbin so that it could get naturally and easily twisted if you went in hurry.

This paper presupposes that the reason for the development of Guanyu's anthropolatry as a cultural phenomenon is derived from, along with Guanyu's loyalism and valor, the people's physiological effects longing for the emergence of a hero, and is closely linked with religious activities to provide the justification of their belief system. Based on this, the purpose of this paper is to study how major religions that is, Confucianism, Buddhism and Taoism take the courses of Guanyu's anthropolatry to their religious advantage and how Guanyu-god is applied to roots in Confucianism, Buddhism and Taoism. In Buddhism, it succeeded in the settlement by upgrading it to jialan-shen that guarded the Buddhist temple, while in Taoism, it was used as a guardian of the san-jie-fu-mo-da-di that chased the almighty devil and deviated from the disaster and suffering. In Confucianism, it was connected to Guanyu's Confucian-commander image to that of chun-qiu-da-yi of kongzi. That is, by symbolizing Guanyu as God of Martial Power and War depending on the country, it was used as a means of governance to establish rules and order.
