This paper is mainly an attempt to approach and rethink regionalism and regional organizations, as a new political phenomenon of our modern world politics, by focusing on the way regime types influence the identity building of Maghreb Arab Unionregional organization in North Africa. The focus of this paper will be on the importance of domestic politics as a non-conventional way of studying regionalism. And unlike many studies of regionalism, generally emphasized by realists and liberalists that focus either on security or economy as an outcome of the old regionalism paradigm, this paper will emphasize domestic politics as a guiding line to understand the regional one.

Since 1971, the aptitude test for domestic train drivers has been long maintained. With the revision of the Railroad Safety Act in 2006, the aptitude test was changed from the type of written and skill test into the type of question-and-answer and reaction test. However, the main structure of the test was not changed. In this paper, we focus our attention on the improvement of the present aptitude test. We surveyed on two groups, one is the railroad expert group and another is train driver's group, questioning about the importance of the domestic and foreign aptitude test items. Based on the analysis, we suggest desirable aptitude test system for the railroad safety.

Feasibility study of the application of a developed annealed austenitic stainless steel at cryogenic temperature has been performed for membrane tank of LNG ship. Chemical properties of developed stainless steel are compared with a domestic commercial stainless steel and a foreign stainless steel which are used for LNG ships. Tensile properties at cryogenic temperature and fatigue strength at room temperature are measured for but and lap joints which are TIG welded specimens. Developed stainless steel having a small amount of titanium component shows the finest grain size in the HAZ, compared with the other stainless steel studied. Tensile strength, elongation and fatigue strength of the developed stainless steel are equal to those of the foreign stainless steel studied and are higher than the domestic commercial stainless steel studied.

The market share of online platform services in the used car market continues to expand. And The used car online platform service provides service users with specifications of vehicles, accident history, inspection details, detailed options, and prices of used cars. SUV vehicle type's share in the domestic automobile market will be more than 50% in 2023, Sales of Hybrid vehicle type are doubled compared to last year. And these vehicle types are also gaining popularity in the used car market. Prior research has proposed a used car price prediction model by executing a Machine Learning model for all vehicles or vehicles by brand. On the other hand, the popularity of SUV and Hybrid vehicles in the domestic market continues to rise, but It was difficult to find a study that proposed a used car price prediction model for these vehicle type. This study selects a used car price prediction model by vehicle type using vehicle specifications and options for Sedans, SUV, and Hybrid vehicles produced by domestic brands. Accordingly, after selecting feature through the Lasso regression model, which is a feature selection, the ensemble model was sequentially executed with the same sampling, and the best model by vehicle type was selected. As a result, the best model for all models was selected as the CBR model, and the contribution and direction of the features were confirmed by visualizing Tree SHAP Value for the best model for each model. The implications of this study are expected to propose a used car price prediction model by vehicle type to sales officials using online platform services, confirm the attribution and direction of features, and help solve problems caused by asymmetry fo information between them.

In the modern society, magazine is a information communicating media which is an important element in assessing the whole of a nation's cultural standard. More subdivided fields of magazines are expanding according to the diversified concepts. As the variety of Korean edition of foreign magazines are increasing, the type of Women's magazines are also diversifying and expanding. By finding out the problems and analyzing the visual side of domestic women's magazines among the intense competition of the magazines, the design improvement program was requested. The analysis result from the visual side of domestic women's magazines tells us that the problem of current domestic women's magazines is that their identities are not clear. The cause can be divided into three reasons: First, it is the lack of creativity and originality. There is a limitation in arousing the readers' interests by designing the magazines with similar layouts. Second, there are no distinct design concepts in the magazines. It seems as if the uniformity is lacked as the impression the magazine gives is not clear. The diversification of layouts and the use of design elements could actually bring about a counter result. Third, the excessive advertisement pages is another reason. The ads that covers over 35% of the whole of the magazine can act as a factor that drops the readers' trust in the magazine.

Over the past decades, in vitro culture media have been developed to successfully support IVF embryo growth in a variety of species. Advanced reproductive technologies, such as somatic cell nuclear transfer (SCNT), challenge us with a new type of embryo, with special nutritional requirements and altered physiology under in vitro conditions. Numerous studies have successfully reconstructed cloned embryos of domestic animals for biomedical research and livestock production. However, studies evaluating suitable culture conditions for SCNT embryos in wildlife species are scarce (for both intra- and interspecies SCNT). Most of the existing studies derive from previous IVF work done in conventional domestic species. Extrapolation to non-domestic species presents significant challenges since we lack information on reproductive processes and embryo development in most wildlife species. Given the challenges in adapting culture media and conditions from IVF to SCNT embryos, developmental competence of SCNT embryos remains low. This review summarizes research efforts to tailor culture media to SCNT embryos and explore the different outcomes in diverse species. It will also consider how these culture media protocols have been extrapolated to wildlife species, most particularly using SCNT as a cutting-edge technical resource to assist in the preservation of endangered species.

This paper examines the associations of having a helper for domestic work or childcare and time spent on it by couples in South Korea. We use five waves of panel survey data from the Korean Longitudinal Survey of Women and Families (KLoWF), which allows longitudinal changes within couples over time that account for potential selection effects and unobserved heterogeneity among individuals. With fixed effects, we find outsourcing is associated with a decrease in wife's time spent on domestic work or childcare by 1 hour per week. However, the decrease is concentrated on the unemployed wife's time, but not employed wife's time. In addition, outsourcing is not a significant factor for husband's time and the husband's share of total contribution. This may be because wives are the main provider of domestic work and childcare in Korea regardless of employment status or having any helper. Due to unequal contributions between husband and wife, using outsourcing also neither alleviates the employed wife's contribution nor changes the husband's contribution. However, the results may be underestimated because there are more common and diverse types of outsourcing in a broad sense, such as going out for dinner, buying prepared food, and using dry cleaning services. We expect future studies to consider more broad types of outsourcing and examine how relations with the couple's time use at home are different by type.
