This study is to propose the improvement of security related regulations to reinforce security activity and actualize constitutionalism in the National Assembly. For the purpose, some improvements could be considered as followings; First, legislating of regulations including some articles on the scope of security activity such as order preservation at assembly hall, facility security, security agents' right and protection of personal is necessary. Second, changing the organization and command system of security management is necessary for the unification of security activity and efficiency of the job. Also clear definition of terminology on the security job is need. For the shake of above object, one officer in charge of situation management and three section such as the personal protection section, facility security section and order preservation section could be substructured under security department. Third, elimination of unnecessary article on the arrest of red handed criminal in the assembly hall and on the physical checkup of audience by security agent is need. Also legislating of regulations on the hoarding of person who could disorder is necessary. Forth, legislating of regulations on the cooperation with government branch, judicial police power, carry and use of weapon and uniform and equipment to reinforce practical efficiency of security activity. For the proper legislating of the regulations, comparition with other public organizations such as presidential security Service, police, private security could be considered.

In recent years, the population composition of rural area is changing due to the decreasing population growth of the aged with disability and people returning to farming. Since 1970's the rural community facilities have been spreaded out across most rural villages. Although the rural community facilities are the most widely used facilities, the existing facilities are need to be new built or remodeled according to demographic changes, usage of facilities, and environmental condition. Given this reality, the rural community facilities such as village assembly hall and nursing home for senior citizen are not only used for daily life place but also used like co-residence having meals and sleeping together. Therefore the rural community facilities have the potential to become welfare service space for rural elderly people. This research focuses on the current situation of universal design applied community facilities. According to the research, most of the village community facilities were built in the 1990s and 82% of the buildings were more than 15 years old. Furthermore, 45% of the village community facilities more than 15 years old most have a ground floor in masonry structure. The area of the building is 65% less than $100m^2$. The width of the access entrance, the height of the sink, gas safety valve and so forth were relatively well designed. However, the handrail of the entrance, space in front of the toilet bowl, the height difference between the entrance and floor, the installation of the width of the ramp and stair handrail was relatively incomplete. Village community facilities to be built in the future should be universal design fundamentally.

Background and objective: This study was conducted to increase understanding of agriculture through agricultural experience programs for adolescents living in self-reliance residence hall, and to investigate changes in work performance ability through changes in hand function. Methods: There were 11 subjects, and the average age was 18.2 years, all males without disabilities. The agricultural experience program consists of a total of 10 sessions including orientation and watching videos on future agriculture, creating vegetable gardens, planting, managing each crop, harvesting, visiting the processing room, and selling at a local food store. Results: The change in agricultural literacy by the agricultural experience program positively improved from a score of 113.73 to 127.91 (p = .008). The changes by sub-item are as follows. The value and safety of agri-foods (p = .020) and agriculture and natural environment (p = .007) were significantly improved. The function and value of rural areas (p = .050), production of agricultural products (p = .160), processing and distribution of agricultural products (p = .248), and agricultural policies (p = .058) were not significantly changed. The simple function of the hands was measured by the number of pegs inserted during 30 seconds, and the assembly function was measured by the number of pegs inserted during 60 seconds. In the case of simple function, the dominant hand was improved from 14.82 to 15.83 (p = .014), andthe non-dominant hand was also significantly improved from 13.79 to 15.01 (p = .002). There was no significant improvement in the simple function (p = .153) and assembly function (p = .770) of both hands. Conclusion: It is considered that the agricultural experience program will enable youths living in self-reliance residence halls to enhance their understanding of agriculture as an occupation, and enable them to play a role as wise consumers by positively affecting improvements in their agricultural literacy and simple hand functions.

The purpose of this study is to examine the reality of the records management of the National Assembly members and suggest a desirable alternative. Until the Public Records Management Act was enacted in 1999, the level of the records management in the National Assembly was not beyond that of the document management in both the administration and the legislature. Rather, the National Assembly has maintained a records management tradition that systematically manages the minutes and bills since the Constitutional Assembly. After the Act was legislated in 2000, the National Assembly Records Management Regulation was enacted and enforced, and the Archives was established in the form of a subsidiary organ of the Secretariat of the National Assembly, even though its establishment is not obligatory. In addition, for the first time, an archivist was assigned as a records and archives researcher in Korea, whose role is to respond quickly in accordance with the records schedule of the National Assembly, making its service faster than that of the administration. However, the power of the records management of the National Assembly Archives at the time of the Secretariat of the National Assembly was greatly reduced, so the revision of the regulations in accordance with the revised Act in 2007 was not completed until 2011. In the case of the National Assembly, the direct influence of the executive branch was insignificant. As the National Assembly had little direct influence on the administration, it had little positive influence on records management innovation under Roh Moo-Hyun Administration. Even within the National Assembly, the records management observed by its members is insignificant both in practice and in theory. As the National Assembly members are excluded from the Act, there is no legal basis to enforce a records management method upon them. In this study, we analyze the records management problem of the National Assembly members, which mainly concerns the National Assembly records management plan established in the National Archives. Moreover, this study proposes three kinds of records management methods for the National Assembly members, namely, the legislation and revision of regulations, the records management consulting of the National Assembly members, and the transfer of the dataset of administrative information systems and websites.

Launched in October 2019, Northrop Grumman's MEV-1 was the world's first unmanned mission demonstrating the practical feasibility of on-orbit servicing. Although the concept of on-orbit servicing was proposed several decades ago, it has been developed to various mission concepts providing services such as orbit change, station keeping, propellant and equipment supply, upgrade, repair, on-orbit assembly and production, and space debris removal. The historical success of MEV-1 is expected to expand the market of on-orbit servicing for government agencies and commercial sectors worldwide. The on-orbit servicing essentially requires the utilization of a highly propellant efficient electric propulsion system due to the nature of the mission. In this study, the space mission analysis for a simple on-orbit mission involving Hall thruster is conducted, which is life extension mission for geostationary orbit satellites. In order to analyze the mission, design space exploration for various Hall thruster design variable combinations is performed. The values of design variables and operational parameters of Hall thruster suitable for the mission are proposed through design space analysis and optimization, and mission performance is derived. In addition, the direction of further improvement for the current on-orbit mission analysis process and space mission analysis involving Hall thruster is reviewed.

Interest is growing in the design and development of square wave driven BLDC permanent magnet motors suitable for industrial automation, and the development of position detection circuits and drivers. However, this motor is somewhat limited in its application despite the price and functional advantages due to the decrease in efficiency due to switching loss and vibration and noise. In the process of designing and assembling a BLDC motor, the magnetic pole angle is not uniform or the magnetic flux distribution is distorted due to problems in magnetic circuit design or product non-uniformity in the assembly process. Therefore, these things cause position detection deviation and deteriorate the motor characteristics. In addition, the sine wave driven BLDC system can operate stably only when the signal generated from the position sensor is accurately fed back to the driver. However, since the generated signal cannot perform stable position detection due to the occurrence of DC offset component due to magnetic flux density deviation or magnetization technology, which is an external influence, this study intends to study the proposed circuit that can remove the DC offset component.

Managing and preserving parliamentary archives are significant national tasks. However, in South Korea significance of these tasks have not been recognized. The first exclusive organization for parliamentary archives management was established in 2000, It took about 50 years after the first South Korean government was established in 1948. The first legislation which regulated parliamentary archives management was enacted in 2001. There were no significant improvement on the regulation for the last decade. In April 2011 it was newly revised according to the amendment of the Act on Public Records Management. In this context this study critically analyzes the regulation and discusses various issues concerning the parliamentary archives management system. It divides the history of parliamentary archives management into four periods. It also explores four contentious issues ranging from parliamentary archive designation to archivists assignment. As a result, the study presents four different aspects for developing parliamentary archives management Each aspect proposes three different phased problems respectively. Keywords: national assembly records management regulation, national assembly archives,

Alteration in chromosome numbers and structures instigate and foster massive genetic instability. As Boveri has seen a hundred years ago (Boveri, 1914; 2008), aneuploidy is hall-mark of many cancers. However, whether aneuploidy is the cause or the result of cancer is still at debate. The molecular mechanism behind aneuploidy includes the chromosome mis-segregation in mitosis by the compromise of spindle assembly checkpoint (SAC). SAC is an elaborate network of proteins, which monitor that all chromosomes are bipolarly attached with the spindles. Therefore, the weakening of the SAC is the major reason for chromosome number instability, while complete compromise of SAC results in detrimental death, exemplified in natural abortion in embryonic stage. Here, I will review on the recent progress on the understanding of chromosome missegregation and cancer, based on the comparison of different mouse models of BubR1, the core component of SAC.

This paper is about the development of Automatic FPC(flexible printed circuit) punching instrument for the improvement of working condition and cost saving. FPC is used to detect the contact position of keyboard and button like a cellular phone. Depending on the quality of the printed ink and position of reference punching point to the FPC, the resistance and current are varied to the malfunctioning values. The size of reference punching point is 2mm and the above. Because the punching operation is done manually, The punching accuracy is varied with operator's condition. Recently, The punching accuracy has deteriorated severely to the 2mm punching reference hall so that assembly of the K/B has hardly done. To improve this manual punching operation to the FPC, automatic FPC punching system is introduced. Precise mechanical parts like a 5-step stepping motor and ball screw mechanism are designed and tested and low cost PC camera is used fur the sake of cost down instead of using high quality vision systems for the factory automation. Test algorithms and programs showed good results to the designed automatic punching system and led to the increasement of productivity and huge cost down to law material like FPC by avoiding bad quality.
