  • This study aims to examine the characteristics and meanings of the encounter between Malaysian migration policy and Korean retirement migration in contemporary Malaysia. For this purpose, I describe and analyze the features and implications of migration policy in Malaysia, and understand the cultural characteristics and meanings of migration policy, especially Malaysian migration policy in Malaysia, and examine and explore the characteristics and meanings of retirement migration, especially Korean retirement migration to Malaysia in contemporary Malaysia, in the socio-cultural context. The research outcomes of this study are followings. Firstly, because of the misunderstanding and misuse of MM2H(Malaysia My 2nd Home) program and Malaysian migration policy among Korean retirement migrants in contemporary Malaysia, Korean retirement migration in Malaysia cannot be regarded one of the appropiate and effective migration policy for Koreans. It has been utilized as an instrument of their children's education among Koreans in Malaysia. Secondly, in this regard, it has been increased the number of Koreans to return to Korea without any constructive results in their children's education and their successful retirement lives in Malaysia. It is noted to understand that Korean retirement migration to Malaysia is the movement and migration of the special forms of human migration or human exchange and cooperation in the socio-cultural context. The cultural characteristics and meanings of Korean retirement migration to Malaysia has been one of the important cultural phenomena between Korea and Malaysia in contemporary Malaysia. In this sense, it is expected that this study can be contributed to understand the cultural characteristics and meanings of the encounter and exchange between Malaysian migration policy and Korean retirement migration to Malaysia in contemporary Malaysia, and to enhance the exchange and cooperation between Korea and Malaysia through human exchange and migration, especially Korean retirement migration to Malaysia in contemporary Malaysia.

  • The orientation density function of the fibers in a yarn has been newly defined and derived for the ideal migration structure, in which the fibers migrate regularly and uniformly from the outside to the center of the yarn and then back to the outside. The ideal migration behavior has been expressed in the mathematical equation by introducing the parameter JM defining rate of migration. The relative initial modulus of the yarn having the ideal migration structure was calculated by using the orientation density function and compared with that of the idealized helical structure. The initial modulus of the yarn has been found to decrease with the increase of the degree of migration.

  • This study develops a model of migration decision-making process, with identifying macrolevel and microlevel factors affecting the process. The model includes some sequential stages : to be dissatisfied with current residential area, intend to move, collect information about alternative destinations, select destination, decide to move, and make actual migration. The macrolevel factors included in the model are environmental, socioeconomic, cultural, and demographic characteristics of the current residence and alternative destinations. The microlevel factors are psychological, socioeconomic, and demographic characteristics of the individual. The effects of the macrolevel and microlevel factors on each stage of migration decision-making process are identified from the previous studies on migration. This study has both theoretical and practical implications. The theoretical contribution will be in the area of integrating the ecological and the individual level perspectives of migration by identifying the macrolevel and microlevel effects on migration decision-making process. This study also has implications for theoretical frameworks guiding empirical analysis of migration behavior of the individuals, and for policies aimed at redistributing population.

  • The solid/liquid interface migration in Nb-doped $SrTiO_3$ and its effect on dielectric properties have been investigated. The specimen sintered in air shows no migration during oxide infiltration treatment in air, whereas the specimen sintered in $5H_2-95N_2$ shows appreciable migration during similar infiltration. In the migrated layers of the specimen sintered in a reducing atmosphere, no cations of the infiltrants are detected by wavelength dispersive spectroscopy. These results show that nonstoichiometry due to the atmosphere change can induce the interface migration as in the case of frequently observed migrations due to solute concentration change. The driving force for the migration is discussed in terms of the coherency strain energy in a thin diffusional oxidized layer of the receding grain. The interface migration caused by nonstoichiometry could be suppressed by preoxidizing grain surfaces before oxide infiltration treatment. The suppression of migration increased the effective dielectric constant of the material.

  • This study presents a rapid method for determining the steady state migration coefficient of concrete by measuring the electric current. This study determines the steady state chloride migration coefficient using the accelerated chloride migration test (ACMT). There are two stages to obtain the chloride migration coefficient. The first stage, the steady-state condition was obtained from the initial electric current at the beginning of ACMT. The second stage, the average electrical current in the steady state condition was used to determine the steady state chloride migration coefficient. The chloride migration coefficient can be determined from the average steady state current to avoid sampling and analyzing chlorides during the ACMT.

  • This paper investigated the chloride invasion resistance properties of concrete containing mineral admixtures(pozzolanic materials such as fly-ash, ground granulated blast-furnace slage, silica fume and meta kaolin) for each replacement ratios under W/B ratios ranged from 40% to 55%. For the electrical migration test, Tang and Nilsson's method was used to estimate the migration coefficient of chloride ion. As a result, the migration coefficients of chloride ion of concrete containing mineral admixtures were shown reducing with the use of mineral admixtures, and the compressive strength was shown related to the migration coefficient. From the correlation between compressive strengths and migration coefficients, the kind and replacement ratio of mineral admixtures have a great effect on migration coefficients below 50㎫.

  • Modern methods of regulating migration processes in EU states include a wide variety of adapted, transformed under the sway of globalization tools in order to influence the movement of human capital within the European space. The main purpose of the regulatory policy on migration flows is the redistribution of professionally competent professionals between different spheres of life. Herewith, the determining factor in the effectiveness of such distribution is a rational combination of stimulating and disincentive levers of influence on the movement of citizens of different EU countries and taking into account the motives of such mobility. Modernization of migration management approaches can be a major economic, social, political and cultural progress of European countries. The purpose of the research is to conduct a detailed analysis of existing practices of migration flow management, in particular their stimulation or containment, and to outline key migration trends formed under the influence of multicomponent approaches to migration regulation, transformation of regulatory legislation and changing priorities of modern society. The research methods: statistical-analytical method; ARIS method; method of tabular, graphical and analytical modeling; comparative analysis; systematization, generalization. Results. Current pan-European methods of regulating migration processes are insufficiently adapted to the multinational socialeconomic space; consequently, there are some disparities in the distribution of migrants between EU countries, although the overall dynamics of migration is positive. Fluctuations in the population of European countries during 2000-2019 and trends in the transformation of social-economic space confirm the insufficient level of influence of current methods of regulating migration flows. Along with this, the presence of a characteristic asymmetry in the distribution of migrants requires a greater focus on the modernization of regulatory instruments, in particular, the regulatory mechanism for managing migration processes. As a result of the conducted study, further prospects for the implementation of alternative methods of regulating migration processes in EU states have been outlined; the current and projected limits for increasing the level of observance of migrants' rights at the European level have been clarified through the adoption of appropriate regulatory acts; effective solutions for intensifying the influx of high-quality labor resources from different countries to EU have been identified. The research results can be used to study methods of regulating migration processes in the countries in the global dimension.

  • The purpose of this study was to investigate the effects of the rural migration factors, degree of preparation for migration, lifestyle conditions and support policies reflected against the family satisfaction of the migration. In this study family factors were used as control variables. Independent variables for this study will consist of the factors of rural migration, the degree of preparation for migration, living conditions of the farmers and the support policies, where as the dependent variable is the satisfaction of migration with an adjusting factor of the family satisfaction which will be further analysed to identify its effects on the dependent variable. For this study, a questionnaire survey was conducted for the residents and 237 valid questionnaires were collected. Multiple regression analysis was performed based on the collected data where demographic attributes being the controlling variable, and regression analysis was performed for the adjusting variable of the family. As the economic factor increases, the level of satisfaction generated to be higher in rural migration. As for the degree of preparation, living condition and support policies resulted, great quantity of green nature, safety and agriculture startup support, respectively, indicated a positive effect to the satisfaction level of migration. From the results, adjustment effect of the family factors on the economic, nature, convenience and satisfaction of the migration have appeared. The conclusion of this study is that policy support, regional stability, and economic gain are the most important factors to increase satisfaction and to reduce re-migration rate to city.

  • Corrosion of the disk has been an ongoing concern for the manufacturers of hard disk drives. With the advent of magnetoresistive (MR) head, very low levels of corrosion and contamination become more critical since the raised defects and corrosion products on the disk surface-anything that heats the MR sensor due to the contact-can distort the output signal of the head. This phenomenon is called as thermal asperity. In this paper, the effect of corrosion as a form of Co migration on the occurrence of thermal asperity in MR drives was investigated. The corrosion test at high temperature (60$^{\circ}C$) and high relative humidity (80%) was emphasized in this study and the testing results at ambient condition were compared. The corrosion on the disks was characterized as the amount of Co ion migration using an ion chromatography (IC) and a time-of-flight secondary ion mass spectroscopy (TOF-SIMS). It is proved that corrosion on the disk surface after storage testing is closely correlated to the amount of Co ions migration from the magnetic layer to disk surfaces and higher Co migration causes more thermal asperities in the drive. In order to reduce Co migration, several methods such as burnishing process and structure of the carbon overcoat were investigated. It is found that the hydrogenated carbon overcoat shows the least Co migration among different types of overcoat layer. However, the most effective way to reduce Co migration is the application of Cr layer between the overcoat and the magnetic alloy layer.
