  • Department of the imperial guard is of the soldiers organization which is formed in the royal power or the absolute near by a king. Thus, department of the imperial guard absolutely is showed it is a soldiers organization for guard a king. We summary the character and the function as followed when we subdivide. 1. The main mission was the guard of the royal palace. As we know from several historical materials, the defense of the royal palace was an fundamental mission. Therefore, department of the imperial guard would take charge of the defense of the royal palace. 2. They would carry out throne of king and the royal family or a battle. As unification, they would carry out guarding for political stability and a suppress probation of internal war in regard to the security and the frequent rebellion in central and locality. 3. They carried out guarding an honored going of a king or the royal family. We know the fact that there was an honored going of the royal family or many attendants on record. When a king or the royal family go, guarding of department of the imperial guard had not only protect them but also show off the authority of the royal family. As a result, when we analysis the substance from studying the guard system of Shilla, though our guard system is imitated the foreign guard system like U.S.A, transcending space-time, the guard system can be found a lot of something common at the guard principle and a rule. Today, in looking about a political system of any countries on the world, a king and a ruler of the country represent their country international, have responsibility of protect their nation and a people internal. Therefore, the guard for a ruler absolutely must carry out at a safety situation. Moreover the guard organ, at the same time is connected directly to a welfare of the nation, so we will have to devote a constant effort.

  • This paper examines the actions and the factors driving those actions to reduce energy consumption and enhance energy efficiency taken by United States cities. While not much empirical evidence is available on why governments pursue practical sustainability actions, we attempt to shed more light on this important topic by empirically identifying factors that contribute to concrete actions toward sustainability policies. We adopt political market theory as a basic theoretical framework with policy-making applied to city energy consumption. Using the 2010 ICMA (local government sustainability policies and program) data, this study expands the focus of analyses to evaluate the effect of the form of government on energy consumption and energy efficiency by using multiple regression analysis. The findings show that at the city level, the mayor-council form of government are negatively associated with governments' efforts to reduce energy consumption. However, cities with at-large elections and municipal ownership are more likely to adopt sustainability actions. We also find that a large-scale economy has significant effects on the effort to reduce city energy consumption and improve energy efficiency. This shows that environmental policies are directly connected to locally relevant affairs, including housing, energy use, green transportation, and water. Thus, local level administrators could take an executive role to protect the environment, encourage the development of alternative energy, and reduce the use of fossil fuel and coal energy. These efforts can lead to important environmental ramifications and relevant actions by municipal governments.

  • Hollow prestressed concrete-filled steel tube (HCFT) piles, which combines PHC piles inside thin-wall steel tubes, were developed to increase the flexural strength of the pile with respect to the lateral load. Since P-M curves are needed for evaluating the structural safety of piles when applying HCFT piles to fields, equations for plotting P-M curves of HCFT piles in limit states were proposed. When the yield strength is applied to the steel tube and PC steel bar of HCFT piles, the proposed equations significantly underestimated the flexural strength of HCFT piles. Unlike the flexural strength test results, the proposed equations also provide greater flexural strengths for 12 mm thick steel pipe piles with the same diameter than for HCFT piles. However, when the ultimate strengths are used instead of the yield strengths for the steel tube and PC steel bar, the proposed equations provide the flexural strengths very close to the flexural strength test results.

  • The purpose of this study is to analyze the symbolic meaning of the Tiger in Korean Folk Paintings, Minhwa, (hereafter, Minhwa) connected to its social contexts in Joseon period. Thinking of the Tiger Minhwa as a 'visual language' and regard the Tiger as a 'visual signifier' as well as the united-signifiers such as a Korean magpie, pine tree and so on in Minhwa. This research is to analyze these signifieds, 'Signified', what we say in this paper, have composed its symbolic meaning related to the social 'ideological complexes' and collective consciousness during Joseon period. In a word, the characteristic of the Tiger signifier has changed and spread out from the ideal trend to a worldly one. Since the late Joseon period, the change of the social contexts was, because of the civil classes who recognized the limitation of the Sung Confucianism(the doctrines of $Chi-Tz\={u}$), the predominated ideology of that time. To get rid of their uneasiness, they brought the Shamanism, Taoism and Buddhism at the front which were usually the lower class ideology or belief and tried to construct the collective consciousness and safety of their real lives. Therefore, the trend of this 'common conceptualization' show us the positiveness and flexibility to the Tiger signifier through the variation, appropriation and producing signifier. Moreover, even to the same Tiger, there were various meanings and most of them were concentrated in the meanings as follows ; Beoksa(in Korean term is to drive away evil spirits) and Gilsang, which is the good omen of a luck. All these were based on the value of 'this world'. In conclusion, through this research, the concept of the Tiger as a apotheosis has lowered its statutes and being secularized.

  • Objective: The purpose of this study was to determine the physical load by identifying harmfully working postures and to develop recommendations for improving the existing situation with nurses in ICU, thereby to provide the basis for development of work-related musculoskeletal preventive program. Method: Various types of tasks were recorded with a video camera to chart and analyze different postures by OWAS(Ovako Working Posture Analysing System). Collected data showed that poor postures were adopted, not only for lifting or repositoning a patient, but also for other tasks. Data Analysis: The performed activities were then divided into Nursing Intervention Classification. Altogether 128 postures were selected for analysis. Then they were classified into different OAC (OWAS Action Categories). From all the observation, unhealthy postures, for which corrective measures had to be considered immediately (i.e., 75% classified as OACII+III+IV) were found. Collected data were analyzed in terms of percentage, 2-tail Mann-Whitney U test. Result: Poor postures mainly occur during 'positioning the patient' and 'airway suctioning' in NIC. No difference was found (p=0.060) between the percentage of harmful posture adopted during the patient handling tasks and non-patient handling tasks. Conclusion: This study shows, that in the nursing profession with ICU not only occur during patient handling, but also during other activities. The OWAS method was useful in determining the physical load by locating potential activities due to harmfully working postures, providing a detailed description with analysis, and suggesting successful means to reduce postural load.

  • In recent years, the importance of the characterization of fall for a fracture prevention system keeps increasing since fracture from a fall can lead to serious health problems. Fall is one of the major sources which increase morbidity in elderly people. In terms of the cost and the influence to the quality of life, the most serious injury with hip fractures is caused by falls. The traditional methods in characterizing fall patterns have been mainly by the epidemiological surveys. With surveys, the exact data of fall patterns can not been acquired. In this paper, we measured and analyzed with the parameters related to fall pattern such as velocities and accelerations during the motion of falls using 3D motion capture program. We acquired the parameters of the fall pattern of intentional and unexpected fall. The result showed that the variation of velocity and acceleration during fall was very important in characterizing fall pattern, which of vital importance for the development of a fracture prevention system and for the safety of the elderly
