This study aims to analysis and measure on the private security for the academic directivity and security industry for the market directivity in Korea. For this study we compare and analysis the curriculum of 15 universities in Korea and the papers which were published on "Korean Security Science Review" that is a report in a professional private security. In conclusion, 269 subjects are used as instructional materials in 15 universities, thus 103 subjects for the private security and 60 for the leisure sports and first-aid treatment, 46 for the social science, 30 for the martial arts and shooting, 16 for the secretary affairs, 14 for the foreign languages. Regarding scientistic papers, 45.7% of papers for the private security of all and 14.6% for the public security, 14.6% for the criminal, and 11.6% for the terror etc. But there are any papers for the facilities guard or security in spite of the facilities guard is pivotal role in this field. The facilities guard or security, or maybe house detective, holds 80.5% of the private security market and it is important role in this industry in Korea. Besides, considering development of private security, the security market makeup the body-guard field hold 12.2%, prevention security system by censor hold 4.1%. So, this statistics show that the facilities guard lead practically the private security industry in this field, but there are any subjects for the education and any research for the paper. Thus some modification on the universities curriculum is required, also needs activity research in the facilities guard field for the development private security.

The area of conservation treatment of the bronze helmet of the ancient Greece, treasure No. 904, which Sohn Keechung (1912 to 2002) received as an extra prize for his winning the marathon in the 1936 Berlin Olympics deteriorated and as a result crack and discoloration occurred. Its nose guard hung downward due to the crack of the bonded area of upper end. Therefore, conservation treatment of the helmet was conducted again. The nose guard was separated from the body. Stabilization and consolidation treatment of them was made and then they were joined again. The cracked and missing areas were reinforced with woven glass fibers, and the nose guard was reinforced with woven glass fibers and Ti plate after the bonding. The joined area of the nose guard was carved with the same pattern as that of the surrounding area and its color was adjusted to be the same as well.

This study aims to analysis and measure on the curriculum of security programs in Korean university as the private security system. Civil security demand social safety life by the police protection and private security system. The private security or the civil guards shows rapid growth by the social development and improve the quality of life. But the supply and training system have some limitations in spite of the high demand guard-secretary. The main role of secretaries has been to accompany superiors in order to maintain their dignity or trait. Then the secretaries are required to play additional roles of safety managers such as a security manager, a protocol manager, an intelligence manager and a protective driver in order to overcome the domestic and the international safety environment and to elevate the quality of service as a competitive work. So, the purpose of this article is to analyze current situation of civil body and security guard training industry and to seek an educational model. For that, we examine in 'Do the professional training organizations meet social demand for the body and security guards'? And, 'What kind of training has to be provide for the body and security guards'? and 'What the qualifications of the trainers'? Then, 'What are the differences in training courses between private organizations and universities'? 'Is there differences in the job placement among the trainers of private organizations and universities'? etc.. Conclusion, the social demand common curriculum for the body and security guard will be drawn from the analysis of diverse training organizations with different training courses in contents, training periods, educational value, and social aim. Then we have to a standard curriculum for the successful training education system to provide social security.

Common-mode noise (CMN) is an unresolved problem in wireless capsule endoscopy (WCE) systems. In a WCE system, CMN originates from various electric currents found within the human body or external interference sources and causes critical demodulation performance degradation. The differential operation, a typical method for the removal of CMN rejection, can remove CMN by subtracting two signals simultaneously received by two reception sensors attached to a human body. However, when there is impedance mismatching between the two reception sensors, the differential operation method cannot completely remove CMN. Therefore, to overcome this problem, we propose an enhanced CMN rejection method. The proposed method performs not only subtraction but also addition between two received signals. Then a CMN ratio can be estimated by sufficient accumulation of division operation outcomes between the subtraction and addition outputs during the guard period. Finally, we can reject the residual CMN by combining the subtraction and addition outputs.

Spawning behavior of the endangered Korean fish, Microphysogobio koreensis, was investigated in the Seomjingang (river), Imsil-gun, South Korea, during the spawning season, April to May 2012. The mating system of M. koreensis, a broadcast spawner, was a primitive spawning mode, and involved one male and one female, unlike group spawning fishes. Spawning behavior of M. koreensis in the wild were observed in eight patterns as resting, male chase, body beating, parallel swim, female withdrawal, male competition, spawning and not guard while spawning behavior in the glass tank were verified in six patterns as resting, male chase, body beating, parallel swim, spawning and not guard. In particular, a behavioral attempt of the pre-spawning stage showed more frequently in the wild than in the glass tank. We assume that difference of spawning behavior might be implication on behavioral restrictions in small and narrow indoor glass tank.

Purpose: This study aimed to identify factors influencing intra-operative core body temperature (CBT), and to develop a predictive model for intra-operative CBT in laparoscopic abdominal surgery. Methods: The prospective observational study involved 161 subjects, whose age, weight, and height were collected. The basal pre-operative CBT, pre-operative blood pressure, and heartbeat were measured. CBT was measured 1 hour and 2 hours after pneumoperitoneum. Results: Explanatory factors of intra-operative hypothermia (< $36^{\circ}C$) were weight (${\beta}=.361$, p< .001) and pre-operative CBT (${\beta}=.280$, p= .001) 1 hour after pneumoperitoneum (Adjusted $R^2=.198$, F= 7.56, p< .001). Weight was (${\beta}=.423$, p< .001) and pre-operative CBT was (${\beta}=.206$, p= .011) 2 hours after pneumoperitoneum (Adjusted $R^2=.177$, F= 5.93, p< .001). The researchers developed a predictive model for intra-operative CBT ($^{\circ}C$) by observing intra-operative CBT, body weight, and pre-operative CBT. The predictive model revealed that intra-operative CBT was positively correlated with body weight and pre-operative CBT. Conclusion: Influence of weight on intra-operative hypothermia increased over time from 1 hour to 2 hours after pneumoperitoneum, whereas influence of pre-operative CBT on intraoperative hypothermia decreased over time from 1 hour to 2 hours after pneumoperitoneum. The research recommends pre-warming for laparoscopic surgical patients to guard against intra-operative hypothermia.

The main purpose of this study was to analyze the reaction time of body guards in different stances to provide quantification of data for educational use. There were 4 martial art trained body guards participating in this study. The results of the EMG analysis and reaction time are as follows. The average reaction time of the whole body was $1.38{\pm}0.07$ seconds. In the first phase the reaction to the signal was $0.22{\pm}0.02$ seconds while in the second phase the reaction after checking was $0.62{\pm}0.10$ seconds, which produced the largest impulse. the reaction times of the third and fourth phase were gradually reduced, $0.29{\pm}0.02$ seconds and $0.26{\pm}0.02$ seconds consecutively. In the body guard posture the following muscles had a high activity level; phase one the right and left of the tibialis anterior muscle, phase two the right and left of the tibialis anterior muscle and the right of the gastrocnemius, phase three the right side of the tibialis anterior and gastrocnemius, phase four the left and right of the biceps femoris and the right side of the rectus femoris. In the first and second phase the shank muscles were used a lot, whereas in the third and fourth phase the shank and thigh muscles were used a lot showing the overall muscle activation of the lower limbs.

The Ministry of Patriots and Veterans Affairs decided to designate Goesan County as a comprehensive venue for determining the geography of the land, the efficient management of land, the public opinion of local residents, and the establishment of a group of civic complaints. In the meantime, Goesan focused on attracting high-ranking government officials, including high-ranking government officials and high-ranking tourist attractions, to attract high-ranking government officials, including high-ranking officials of the National Guard, to promote the nation's bid to attract high-ranking government officials. In this paper, we intend to conduct a study centered on the controversy over the survival of the Korean National Guard. conflict between local governments is a non-authoritative administrative administrative body, it can be regarded as a matter of difficulty by intervening in any autonomous matter, and ultimately, it can be changed to judicial judgment. This is not to say that the residents of Goesan county will protest this time. Even though Goesan promotes regional development and development for local residents, it can not guarantee that the judgment of Goesan County will be held in the same situation. Thus, it should develop a win-win strategy based on the threat of sabotage. To this end, I would like to suggest the following measures.

A small guard robot working indoors or outdoors can be used to report various information on its environment to an operator. The guard robot should be small-sized and lightweight to increase its portability. In addition, it should be able to overcome a relatively high obstacle to cope with various situations. To satisfy these requirements, this paper presents a small robot equipped with a novel hybrid wheel and track mechanism that can select wheels or tracks depending on the situation. The robot folds the tracks into the body in the wheel mode and only wheels are active with the tracks immobilized, which results in the fast moving speed. In the track mode, the tracks are extended to keep in contact with the ground. Furthermore, this research proposes the belt length maintenance mechanism by which the belt length is kept constant in either the wheel or track mode. Various experiments demonstrate that the proposed robot can move fast by using wheels on the smooth terrain and overcome obstacles by using tracks on the rough terrain.
