The reform of dress regulation in Kapshin(甲申衣制改革; 1884) was the first dress renovation in 8 years after Chosun's port opening in 1876, and the key contents of that reform was the simplification of the formal dress and private dress. The reform in the culture of the traditional costume should require some kind of special experience because that culture had been regarded as the precious symbol of the Confucianism. The purpose of this study is to investigate the background of "the reform" and who proposed "that reform", by contemplating the costume and the thought of costume of the ambassador extraordinary(修信使) and the Inspectors detached to Japan(朝士視察團) who experienced new costume system of Japan sent by Chosun Dynasty. For this study, historical documents such as 'Sillok(實錄)', a sort of report("修信使記錄", "聞見事件") were reviewed and the evidential photos in Japan were analyzed. It can be summarized as follows. First, Kim Kisu(金綺秀, Susinsa) in 1876 and Kim Hongjip(金弘集, Susinsa) in 1880 wore the traditional costume of Chosun in Japan, and described the westernized Japanese costume in view of traditional costume culture. Second, the inspectors detached to Japan in 1881 showed the same attitude to the Japanese costume as the previous Susinsas had done. Third, Park Younghyo(朴泳孝), who was an ambassador extraordinary and plenipotentiary(特命全權大使) in 1882, experienced western style in Japan and played an positive diplomatic activities with western nations. It could be guessed that those changes in the attitudes of the diplomats might have the relationship with the change of Chosun, which began a treaty of amity between western nations after 1882. Afterwards, Chosun seems to have decided to reform the system of traditional costume into the simplified one in 1884, proposed by the diplomats who experienced foreign culture abroad including Park Younghyo(朴泳孝) and the mutual agreement in Chosun Government.

The construction environment has the trend of oversizing and professionalizing, the increase of the construction period, and the risk factors and the uncertain factors which are important in the construction bid. The misunderstanding and the lack of knowledge of the subcontractor result in the decrease of the profit or the deficit. In conclusion, these are supposed to give the financial burden to the subcontractor. So, it is very important to predict the construction preparation cost calculation by the risk factors in the bidding stage and to calculate the bid unit cost considering the target profit of the subcontractor in the process of the mutual agreement and performance of the contract. In these points of view, this study analyzes how the importance of the risks influencing the bidding cost calculation affect the construction cost, and this analysis can be used as the basic data to establish the suitable bid strategy of the subcontractor.

Korean administrative jurisdiction has changed from separation to integration system, without definite raison d'etre from the effectiveness dimension. It partially comes from the fact that the top priority of most existing documents has given to the behavioral patterns of key variables during specific time periods. As an alternative approach, this study focuses on dynamic analysis on the long-term structural patterns related to urban-rural integration issues. Specifically, it pays attention to unique experiences between two neighboring administrative authorities, namely Cheongju and Cheongwon, all of which have repeated exceptional confrontations between pros and cons over almost two decades. From the theoretical perspectives, this observes structural similarities and differences between separation and integration approaches and compares individual feedback loops in order to examine urban-rural integration effectiveness. Structurally, if the integrated local authority adopts systematic management and balanced territorial development principles, it would gain the highest positive effect of urban-rural integration. After scenario buildings, it analyzes administrative integration dynamics between Cheongju and Cheongwon, highlighting geo-political conditions, key issues, and implementation plans between two administrative authorities. It expects that the integrated jurisdiction as a whole would increase the urban attractiveness as it can facilitate territorial development plans from macro-level. Furthermore, if the integrated authority keeps balanced territorial principles, which would be well reflected in the mutual agreement between two administrative units, it would also guarantee the increased urban attractiveness in the integrated jurisdiction. Nonetheless, compared to Cheongwon, which might be wider open to the location of NIMBY facilities, it would be more difficult for Cheongju to pay attention to territorial development confined to its original jurisdiction in the short run.

Administrative ADR to solve new problems has the characteristics of a new project, hence ADR is established and operated with a lack of human and material resources in the process of introducing administrative ADR. Therefore, it is preferred to resolve conflicts by less costly counseling and mutual agreement before mediation. When we try to settle the disputes through administrative ADR at the stage before mediation, it causes problems for the neutrality and impartiality of the dispute settlement procedures. In this case administrative ADR systems should introduce devices that ensure the impartiality of the process. In some issues becoming social problems, relevant administrative agencies are inclined to establish ADR systems. If ADR systems become available, a person who may use ADR services may have some trouble grasping ADR institutions because he/she can hardly distinguish their business affairs. By subdividing administrative affairs, when the disputes have the issues that touch on various fields of the affairs, parties in the disputes have to take ADR procedures one by one in all ADR-related institutions. This may lead to too heavy a burden on the disputing parties, furthermore forcing them to give up the remedies of their rights. For more efficient ADR operations, it is necessary that the institutions which set up and operate ADR systems should actively exchange and cooperate with one another. They need to forge and strengthen the solidarity between administrations and courts. The administrative agencies which run ADR themselves have to build up the devices for preparing human resources and material facilities for administrative ADR.

A study of facility securement and space utilization at national universities in Korea was conducted in order to help develop an efficient model for space management at national universities going forward. For the study, 36 national universities were asked to submit answers to a questionnaire on usage of campus facilities in 2013. We then analyzed the results of space management for the 27 universities that participated in the questionnaire in each of the past three years (2011-2013). Lastly, we conducted an awareness test on the space utilization policies and space management for these universities. The results are as follows. First, the aggregate average score for space utilization over the past three years is 74.06. The annual average score increased year-over-year and then decreased; it was 69.44 in 2011, 80.68 in 2012, and 72.05 in 2013. A decline in the sense of responsibility of universities to effectively manage space appears to be a factor in the decrease. Second, with 53% of respondents in agreement, treatment of campus area as private space appears to be the biggest hurdle for efficient space management. As such, a plan to foster a more communal view of campus facility area is required. Third, resistance from constituents to existing guidelines for space allocation on campuses appears to be limited (78.1% of respondents answered the guidelines currently in place were average, satisfactory, or very satisfactory). We believe this result points to a mutual understanding forming amongst constituents regarding guidelines on space allocation on campus.results of satisfaction research: the users are generally satisfied with education and student.

The study is concerned with the rigid-plastic element analysis for axisymmetric hydromechanical deep drawing in which the fluid flow influences the metal deformation. Due to the fluid pressure acting on the sheet material hydromechanical deep drawing is distinguished from the conventional deep drawing processes. In considering the pressure effect, the governing equation for fluid pressure is solved and the result is reflected on the global stiffness matrix. The solution procedure consists of two stages ; i.e., initial bulging of the sheet surface before the initiation of steady fluid flow in the flange and fluid-lubricated stage. The problem is decoupled between fluid analysis and analysis of solid deformation by deformation by iterative feedback of mutual computed results. The corresponding experiments are carried out for axisymmetric hydro-mechanical deep drawing of annealled aluminium sheet as well as for deep drawing. It has been shown from the experiments that the limit drawing ratio for hydro-mechanical deep drawing is improved as compared with deep drawing. The computed results are in good agreement with the experiment for variation of punch head and chamber pressure with respect to the punch travel and for distribution of thicknees strain. It is thus shown that the present method of analysis can be effectively applied to the analysis of axisymmetric hydro-mechanical deep drawing processes.

The perovskites in the $LaAlO_3-BaZrO_3$ system (i.e., $(1-x)LaAlO_3-xBaZrO_3$ were fabricated by a solid state reaction and their dielectric properties were investigated. For the compositions of x=0.1~0.9, the mixture of $LaAlO_3$ with a rhombohedral structure and $BaZrO_3$ with a cubic was observed when the sintering was conducted at $1500^{\circ}C$, indicating that the solubility of constituent elements was very low and a narrow solid solution region might exist. The large difference of ionic radii between $La^{3+}$ ion (0.136nm, C.N.=12) and $Ba^{2+}$ ion (0.161nm) or $Al^{3+}$ ion (0.0535nm, C.N.=6) and $Zr^{4+}$ ion (0.072nm) might hinder the mutual substitution. Within the compositions of x=0~0.7, the dielectric constant of the mixture increased with the amount of $BaZrO_3$, i.e., x value, which was in good agreement with the logarithmic mixing rule (In $_{r,i}={\Sigma}v_iln\;_{r,i}$). The increase in $BaZrO_3$ doping decreased $Q{\times}f$ value significantly due to the low $Q{\times}f$ value of $BaZrO_3$ itself, a poor microstructure of the mixture with an increased grain boundary area per volume, and defects in the cation and oxygen sub-lattices which were respectively caused by the evaporation of barium during the sintering process and the substitution of Ba on La-site or Al on Zr-site.

Each cloud service has numerous owners and tenants, so it is necessary to construct a privacy preserving identity management and access control mechanism for cloud computing. On one hand, cloud service providers (CSP) depend on tenant's identity information to enforce appropriate access control so that cloud resources are only accessed by the authorized tenants who are willing to pay. On the other hand, tenants wish to protect their personalized service access patterns, identity privacy information and accessing newfangled cloud services by on-demand ways within the scope of their permissions. There are many identity authentication and access control schemes to address these challenges to some degree, however, there are still some limitations. In this paper, we propose a new comprehensive approach, called Privacy pReserving Identity and Access Management scheme, referred to as PRIAM, which is able to satisfy all the desirable security requirements in cloud computing. The main contributions of the proposed PRIAM scheme are threefold. First, it leverages blind signature and hash chain to protect tenant's identity privacy and implement secure mutual authentication. Second, it employs the service-level agreements to provide flexible and on-demand access control for both tenants and cloud services. Third, it makes use of the BAN logic to formally verify the correctness of the proposed protocols. As a result, our proposed PRIAM scheme is suitable to cloud computing thanks to its simplicity, correctness, low overhead, and efficiency.
