Domestic vehicle registration is continuously increasing every year, traffic accidents are also increasing by an increase in the number of vehicles. In the event of a traffic accident, the perpetrator and the victim should be judged and handled appropriately. When judging the accident situation, the black box is what evidence can be except for witness who is at the accident scene. The black box becomes an essential role in order to prevent traffic accidents. However, there is no way to prove integrity by evidence corruption, fabrication and etc. For this reason, we propose a method to guarantee the integrity of image through hash value generated by using PingPong 256 encryption algorithm for integrity verification in this paper.

Nowadays, authentication is essential to identify the legal users in a network communication. Usually, there are few wars to achieve authentication over a publicly accessible network system in order to protect certain private data from the unauthorized users, ranging from simple ID/Password to Biometrics System. One of the most active areas in OTP(One Time Password) research today aims at exploiting OTP to provide authentication in the finance and security industry. OTP is usually discarded once it has been used. this prevents huge loophole of traditional authentication system which employs the same ID and Password every time. However this OTP system also has its weaknesses in surviving some attacks. this paper proposes an advanced OTP protocol using PingPong-128 without loop hole of pre-existing OTP.

In the internet communication technology, authentication of the user is main task. So far, very popular researches have been proposed for user authentications based on user_id and password. These existing methods have some merits as well as demerits also. In this paper, we analyzed the existing authentication method problems and implement a secure PingPong-128 based key generator for internet technology. In our new scheme, we are using one time password and security card numbers to generate the secure tokens for the user and internet service provider.

In the future, a machine-tool will be more improved in the form of a knowledge evolution based device. In order to develop the knowledge evolution based machine-tool, this paper proposes the structure of knowledge evolution and the scheme of a dialogue agent among agent-based modules such as a sensory module, a dialogue module, and an expert system. The dialogue agent has a role of interfacing with another machine for cooperation. To design of the dialogue agent module in M2M(Machine To Machine) environment, FIPA-OS and ping agent based on FIPA-OS are analyzed in this study. Through this, it is expected that the dialogue agent module can be more efficiently designed and the knowledge evolution based machine-tool can be hereafter more easily implemented.

To establish feline electroacupuncture anesthesia, 5 cats (mixed, 1 month old, 0.4~0.5 kg, female) were examined in the present study. The acupoints used for feline electroacupuncture anesthesia were Tian-ping and Bai-hui. After perpendicular insertion of needle to Tian-ping and Bai-hui, respectively, positive electrode was connected at Tian-ping and negative electrode was connected at Bai-hui, respectively, Electric condition was 3 V and 30 Hz. To examine the effect of electroacupuncture anesthesia, laparotomy (5 heads)was applied. The pain of the body surface and the extremities excluding the tail was not found, and the induction time of electroacupuncture anesthesia was approximately 1 minute. As for the reactions with electroacupuncture anesthesia, the head part was directed to backward, blepharoreaction was mild and the consciousness was vivid. The class of anesthesia effect was excellent in 4 heads and was poor in 1 head. The pain was not observed and bleeding was comparatively small volume during surgery in excellent group.

The objective of this paper is to analyze and characterize to simulate routing observations on end-to-end routing circuits and a ping experiment of a virtual network after modeling, such as IPv6 migration, an OSPFv3 routing experiment based on an IPv6 environment, and a ping experiment for IPv4/IPv6 dual-stack networks and IPv6 network for OSPFv3 routing using IPv6 planning and operations in an OPNET Modeler. IPv6 deployment based largely on the integrated wired and wireless network was one of the research tasks at hand. The previous studies' researchers recommended that future research work be done on the explicit features of both OSPFv3 and EIGRP protocols in the IPv4/IPv6 environment, and more research should be done to explore how to improve the end-to-end IPv6 performance. Also, most related work was performed with an IPv4 environment but lacked studies related to the OSPFv3 virtual network based on an end-to-end IPv6 environment. Hence, this research continues work in previous studies in analyzing IPv6 migration, an OSPFv3 routing experiment based on IPv6, and a ping experiment for IPv4/IPv6 dual-stack networks and IPv6 network for OSPFv3 routing. In the not too distant future, before enabling the default IPv6, it would help to understand network design and deployment based on an IPv6 environment through IPv6 planning and operations for the end-user perspective such as success or failure of connection on IPv6 migration, exploration of an OSPFv3 routing circuit based on an end-to-end IPv6 environment, and a ping experiment for IPv4/IPv6 dual-stack networks and IPv6 network for OSPFv3 routing. We were able to observe an optimal route for modeling of an end-to-end virtual network through simulation results as well as find what appeared to be a fast ping response time VC server to ensure Internet quality of service better than an HTTP server.

The PingMaiFa chapter, which is the second chapter of SongBon ShangHanLun, is the scholarly description(專論) of the pulse and pathological mechanism but has not been studied and published yet. This study is about article 1-13 which is the first part of The PingMaiFa chapter. We compared the original texts within the editions, comparing and analyzing the annotations of successive dynastic medical group. The articles of The SongBon ShangHanLun PingMaiFa chapter 1-13 is consisted as is shown: article 1 states about the general features of normal pulse (平脈) and its physiological mechanism and the morbid pulses (病脈) caused by wind, cold, retained fluid, pain and heat vexation, article 1,10 state about the normal pulses of Five viscera (lung, heart, spleen, liver and kidney) and their manipulations in pulse taking, article 2 states about the differentiations of deficiency and excess syndrome according to pulse conditions, article 3, 4 state about the estimation of good prognoses and a factitious disorder by the combination of pulses and symptoms, article 6 states about Latent qi (伏氣) and its diagnostic features, article 5 states about inspection and listening examination as co-diagnostic methods of the pulse diagnosis, article 7, 8, 9 state that the emotions, such as fear and shame, and the dietary are important factors to consider for making diagnosis, article 11 states about the overwhelming pulse (相乘脈) which indicates the abnormal correlations between five phases and appears in four patterns as the dissolute(縱), the unrighteous(橫), the unfavorable(逆) and the favorable(順), article 12 states about 6 harmful pulses(殘賊脈), which are string-like pulse(弦脈), tight pulse(緊脈), floating pulse(浮脈), slippery pulse(滑脈), sunken pulse(沈脈), rough pulse(澁脈), article 13 states about "JaeGoe"(災怪) which is an unexpected response after treatment and it comes because of the formulas that had before. Throughout all these articles, The PingMaiFa chapter not only offers great value for Pulse-taking diagnosis, but also leads to a better understanding of clinical applications.

Drawing a sample can be costly or time consuming in some studies. However, it may be possible to rank the sampling units according to some baseline auxiliary covariates, which are easily obtainable, and/or cost efficient. Ranked set sampling (RSS) is a method to achieve this goal. In this paper, we propose a modified approach of the RSS method to allocate units into an experimental study that compares L groups. Computer simulation estimates the empirical nominal values and the empirical power values for the test procedure of comparing L different groups using modified RSS based on the regression approach in analysis of covariance (ANCOVA) models. A comparison to simple random sampling (SRS) is made to demonstrate efficiency. The results indicate that the required sample sizes for a given precision are smaller under RSS than under SRS. The modified RSS protocol was applied to an experimental study. The experimental study was designed to obtain a better understanding of the pathways by which positive experiences (i.e., goal completion) contribute to higher levels of happiness, well-being, and life satisfaction. The use of the RSS method resulted in a cost reduction associated with smaller sample size without losing the precision of the analysis.

Recently, the conventional concept of a machine-tool in manufacturing systems is changing from the target of integration to the autonomous manufacturing device based on a knowledge evolution. Subsequently, a machine-tool has been the subject of a cooperation through an advanced environment where an open architecture controller, high speed network and internet technology are contained In the future, a machine-tool will be more improved in the form of a knowledge evolution based device. In order to develop the knowledge evolution based machine-tool, this paper proposes the structure of knowledge evolution and the scheme of a dialogue agent among agent-based modules such as a sensory module, a dialogue module, and an expert system. The dialogue agent has a role of interfacing with another machine for cooperation. To design of the dialogue agent module in M2M(Machine To Machine)environment, FIPA-OS and ping agent based on FIPA-OS are analyzed in this study. Through this, it is expected that the dialogue agent module can be more efficiently designed and the knowledge evolution based machine-tool can be hereafter more easily implemented.
