High level radioactive wastes, such as spent fuels generated from nuclear power plant, will be disposed in a deep geological repository. To maintain the integrity of the disposal canister and to carry out the process effectively, the emplacement process for the canister system in borehole of disposal tunnel should be well defined. In this study, the concept of the disposal canister emplacement process for deep geological disposal was established. To do this, the spent fuel arisings and disposal rate were reviewed. Also, not only design requirements, such canister and disposal depth but also preliminary repository layout concept were reviewed. Based on the requirements and the other bases, the canister emplacement process in the borehole of the disposal tunnel was established. The established concept of the disposal canister emplacement process will be improved continuously with the future studies. And this concept can be effectively used in implementing the reference repository system of our own case.

The orifice establishment which is improper does to change the entity differential pressure and occurs an error in flow measurement data. Because of this, the thermal power of nuclear power plant could be evaluated excessively and the safety margin could be decreased. In this paper, characters of orifice which is established abnormally was investigated. Specially, the orifice plate which is established in opposition case was modeled and analyzed. Finally, 14.4% was lowly measured differential pressure, when being established in the resultant opposition. And this result with EPRI and NRC experiences was similar.

The chemical behavior and properties related to the redox state of environmental pollutants were investigated using electrochemical methods. Measurements were taken of variations in the redox potential and cyclic polarization current. The results established the influence of various factors, including concentration, temperature, salt, and pH, on the redox potential and current. These factors were determined to effect the result of the redox reaction. Optimum conditions were also established for each case. It was clearly established that the electrode reaction was from a reversible to an irreversible process, plus it was also mixing reaction current controlled.

According to the economy recession of U.S.A and Europe, the value of China market has been increased. Therefore the in-depth studies were essential for the companies and brands which look for new rising market. This study typed Chinese consumers by lifestyle and analyze the demographics and clothing purchasing behavior. The result of the internet survey which was carried out targeting Shanghai residents, established several consumer types of men and women respectively. In case of male consumers, established 4 groups like indifferent to advertising/brand group, seriously considering brand/health group, seriously considering leisure group, and seriously considering education group. In case of female consumers, established 3 groups like seriously considering education/food group, seriously considering housing/leisure group, and seriously considering shopping group. These groups were showed significant differences to demographics and clothing purchasing behavior. These characteristics about the groups must be reflected to marketing and merchandising strategies.

To make railway carbody light in weight has advantages at some aspects of both manufacturing and maintenance. Recently, railway carbodys of steel structure have been lightened their weight by using aluminum extrusion plate. for the additional lightening of railway carbody, an optimal design which maintains proper strength and minimizes weight must be achieved. Optimization which is used with finite element analysis for aluminum extrusion plate has the disadvantage of consuming much time. In this paper, the method of equivalent material property which is available to FEA code is established using the method of equivalent stiffness. This method for plate is expanded into the method for railway carbody structure with plates and shells. An objective function is established for maximum stiffness of unit aluminum extrusion plate using established method of equivalent material property. We performed an multi-objective optimization using the penalty function method. As a result, recommendable shapes and sizes of unit extrusion plate for under-frame of high speed train is presented.

Disaster mitigation, especially as a concept similar to damage mitigation caused by heavy rainfalls and flood is closely related to long-term development plan. This plan of an harbor area where is located in lower region is established and carried under consideration of disaster mitigation concept such as internal drainage and so on. Flood damage is somewhat predictable in accordance with height, stream and rainfall characteristics of the region. Therefore it is necessary to establish national and urban plan under consideration of this fact. But this consideration of existing regulation and institution is insufficient and improvement of regulation and institution is needed. This consideration of disaster mitigation fields is regulated declaratively and inclusively in national plan which is established in broad region, and specifically and detailedly in urban plan which is established in narrow region. The program to improve regulation and institution is proposed in order to consider disaster mitigation fields as a level of this plan.

Taking the four-wheel bogie landing gear as an example, the force status of truck-like landing gear during the landing impact was analyzed and the simulation model of four-wheel bogie landing gear was established. Firstly, a landing gear prototyping model was established using CATIA and imported to LMS Virtual.lab. Secondly, dynamic analysis of the landing impact was simulated with the established model. Finally, with the help of LMS Virtual.lab's parametric design ability, the effects of landing approach and truck pitch angle on the landing performance, truck motion and truck beam strength were studied. These conclusions will be useful to the design and analysis of the truck.

Product liability is an important regulation factor in automotive industry. ISO 26262 international standard was established as an exemption clause of product liability. In autonomous car, product liability becomes more important, and ISO/PAS international standard was additionally established, but it can be applied to only sensing stage, which can partly make the autonomous car companies exempt the product liability but not completely. Therefore, reform of current legal system is absolutely necessary to commercialize autonomous car until a new international standard is established as a complete exemptions clause.

The conceptions of generalized b-metric spaces or G_b-metric spaces and a generalized Ω-distance mappings play a key role in proving many important theorems in existence and uniqueness of fixed point theory. In this manuscript, we establish a new type of contraction namely, Ω_b(𝓗, 𝜃, s)-contraction, this contraction based on the concept of a generalized Ω-distance mappings which established by Abodayeh et.al. in 2017 together with the concept of 𝓗-simulation functions which established by Bataihah et.al [10] in 2020. By utilizing this new notion we prove new results in existence and uniqueness of fixed point. On the other hand, examples and application were established to show the importance of our results.

This paper traces the process how Confucianism was established as a state ideology in Vietnam. Confucianism is said to have first been introduced into Vietnam around the early 3rd century. However, it had been outshone by Buddhism until the 1389s when Ho Quy Ly rose to power and emphasized pre-Qin Confucianism. In 1428, Lê Loi founded a new dynasty and changed the state ideology from Buddhism to Confucianism. Despite this radical shift, however, Confucianism was not firmly established at the beginning of the Lê Dynasty. It was Lê Thanh Tong (1460-1497) who fully established neo-Confucianism as the state ideology. The reason was that he devoted himself to the study of Confucian texts from a young age and sought to strengthen his own royal authority by emphasizing the neo-Confucian concept of loyalty and filial piety.
