This article investigates how Baedal Minjok(BaeMin) has grown to be a dominant mobility platform operator in food delivery sector in South Korea and what roles its brand and branding have played in the process, drawing on the idea of origination. For the purpose, BaeMin is considered as a typical platformized mobility service provider and origination is framed to be an appropriate analytical lens for the business sector. For the origination conception, unlike mainstream neoclassical theory and concepts, is able to deal fairly well with the issues of imperfect competition, imperfect information, and monopolistic brand rent, which are apparent in today's platformized mobility services. Drawing evidence from textual data, empirical analysis pays particular attention to discursive and symbolic dimensions of BaeMin's socio-spatial biography. It is found that national origination underpinning ethnicity comprises an important pillar of BaeMin's brand and branding. Another form of place-based origination is also observed to matter, especially in the varied relation between the mobility service brand's owner and consumers. However, this configuration of BaeMin's brand origination has yet to be fully stabilized, as it has faced with serious challenges including brand vandalism and anti-brand movement especially since its merger to German food delivery platform giant Delivery Hero in 2020. This origination crisis moment appears to be associated with a series of contractions intrinsic to so-called 'platform capitalism'.

This study examines how prospective earth science teachers perceive the concept of "equilibrium" and "interaction between Earth's spheres" in understanding Earth's radiative equilibrium and tries to identify their misconceptions. For this purpose, a questionnaire was designed and put to them to look into their thought flow based on the items that appeared in the national level evaluation. As a result of analyzing their answers, even though all the prospective teachers correctly described the concept of radiative equilibrium, about 90% of them did not apply the concept of radiative equilibrium to the new environment of the Earth without atmosphere. They do not seem to be able to smoothly derive the concept of a new 'interaction' between the changed regions and a new 'equilibrium' that will be reached over a long period of time. In this respect, it is likely that the textbooks had some influence on the formation of their concepts. In particular, high school Earth Science textbooks describe the Earth's radiation equilibrium in a quantitative manner, focusing on the heat budget of the equilibrium state rather than the process of reaching radiation equilibrium. Such an approach of textbooks might be an obstacle to fostering students into creative convergence-type talents pursued in the 2015 revised curriculum. Meanwhile, in order to eliminate the misconceptions of students often found in the understanding of Earth's radiation equilibrium, this study suggests that the core concepts need to be dealt with more attention even in college courses for training prospective teachers.

The purpose of this study was to investigate the views of Joseon held by Kano Jigoro, who was the creator of judo and spread the martial arts ideology across the world, to shed light on the fundamental essence of the martial arts ideology spread around Korea. Conducted in this perspective, the study generated the following results: first, Kano Jigoro grew up, receiving history education from classical scholars of Japan. He was accordingly influenced by the Seikanron, which argues that Empress Jingu, a mythical character, conquered Silla, Baekje and Gaya. The Seikanron became the basis of the Imna Ilbonbu theory during the Japanese rule and was projected onto martial arts ideas Jeongryeokseonyong and Jatagongyeong that were completed by Kano Jigoro and introduced into Joseon. Secondly, Kano Jigoro distributed and expanded the tale of statehood in the prism of martial arts ideology since the Meiji Restoration, which was possible because he connected his martial arts ideas to the statehood of Japan. As a result, they were used as the logic of Korea and Japan are One in Joseon unlike the rest of the world where they were applied as peace ideas. Finally, his martial arts ideology introduced into Joseon during the Japanese rule went through acculturation and showed the contradiction of being interpreted differently according to different individuals. Most Japanese people made use of his martial arts as a means of the Korea and Japan are One policy, whereas the pioneers of the Korean people excluded Kano Jigoro's view of state, included the nationalistic features in it, and trained their martial arts as a means of overcoming the national crisis.

In August 2022, even though flood damage occurred in the metropolitan area due to heavy rain, drought warnings were issued in Jeolla province, which indicates that the regional drought is intensified recent years. To cope with regarding intensified regional droughts, many studies have been conducted to identify spatial patterns of the occurrence of meteorological drought, however, case studies of spatial clustering for water shortage are not sufficient. In this study, using the estimations of water shortage in the Han River Basin in 2030 of the Master Plans for National Water Management, the spatial characteristics of water shortage were analyzed to identify the hotspot areas based on the Local Moran's I and Getis-Ord Gi^*, which are representative indicators of spatial clustering analysis. The spatial characteristics of water shortage areas were verified based on the p-value and the Moran scatter plot. The overall results of for three anayisis periods (S0(1967-1983), S1(1984-2000), S2(2001-2018)) indicated that the lower Imjin River (#1023) was the hotspot for water shortage, and there are moving patterns of water shortage from the east of lower Imjin River (#1023) to the west during S2 compared to S0 and S1. In addition, the Yangyang-namdaecheon (#1301) was the HL area that is adjacent to a high water shortage area and a low water shortage area, and had water shortage pattern in S2 compared to S0 and S1.

The purpose of this research is to comparatively meta-analyze the total, short-term, and long-termeffectiveness of cases involving care of the elderly depression in the age range of 60 and over in the four countries, and to identify the relevant policy implications for developing depression care programmes for Korean older people. Ten studies conducted by RCT were found via AMED, EMBASE, Ovid Medline, PsycInfo. Use of Review Manager(5.5 version) shows that the interventions for caring depression were all effective: total effectiveness is OR=0.47(95% CI), short-termeffectiveness is OR=0.37(95% CI), and long-term effectiveness is OR=0.61(95% CI). This research provides three policy implications: Firstly, elements for increasing the long-term effectiveness of depression care interventions should be applied to all new programmes for caring elderly depression. Secondly, more focused depression interventions should be applied during the first half period of care programmes for elderly men, whilst the focus should be shifted to the last half period for elderly women. Finally, new interventions for caring depression that integrate both the medical and social support model of depression should be designed for elderly Koreans.

What are the implications for us through the discussion on the effect of Germany's dual system of vocational education on the youth unemployment rate? You can find out what kind of evaluation Germany is receiving on the dual system vocational education system implemented based on the 'Vocational Education and Training Act' (Berufsbildungsgesetz), and the specific system establishment form for the industry-academic-government cooperation system. It was possible to present the crises and problems of these systems. Responsibility for the dual system of vocational education in Germany rests with the national and state ministries of education, and private enterprises and chambers of commerce are responsible for business practices. Practical work in a company is conducted through skill-oriented education, and in vocational schools, competency-oriented theoretical education is received. In addition, the necessity and demand for digital vocational and education training in accordance with German Idustrie 4.0 and higher vocational education degree acquisition through dual-degree courses were identified. It can be seen that the youth unemployment rate is the lowest in Europe due to the successful development and utilization of human resources to improve the competitiveness of companies, such as dual vocational education and training (VET) at all levels, higher vocational education at universities, and continuing vocational education programs. Vocational education in Korea will also be able to improve the unemployment rate by establishing a system that allows schools and businesses to conduct vocational education and training simultaneously. In particular, it was possible to judge the necessity of 'close consultation between labor, management, and government', which we consider the most important and should lead to in-depth discussion and cooperation for dual education between vocational schools and companies.

This study is to carry out literary study about the subject of Martial Study in Song Dynasty which was in charge of military strategy education. Martial Examination and Martial Study were related to military officials in China, and also have important value of historical materials in physical education dealing with martial arts as traditional physical activity. To be a military official would be possible to correspond with such requirements as knowledge that sports experts should have, leadership as a leader, and ability reinforcement through physical training, and the effort to pass Martial examination as the chance of status rise contributed to developing sports and culture because the necessity of training military arts was emphasized in social situations. Martial Study establishment became a clue of creating and spreading the notion that General should have virtue and justice as an ideological style of new-Confucianism (neo-Confucianism and Sung Confucianism) in Song Dynasty. After founded in 1043 and equipped with a formal aspect in 1072, Martial Study got the political effect and improved national competitiveness while its function of cultivating and selecting excellent capable persons was going on smoothly. Educational contents in Martial Study were understanding and flexibly applying the skills of infantrymen, cavalrymen, and bowmen and the meanings and theories of confucian classics, testing problem solutions of reality, and teaching the measures of the problem. Martial Study included three aspects of military capable persons, war, and weapons and took charge of the function of education, selection, and promotion, steadily supporting development and continuance of Martial examination institution.

Recent intensification of climate change has led to an increase in damages caused by droughts. Currently, in Korea, the Standardized Precipitation Index (SPI) is used as a criterion to classify the intensity of droughts. Based on the accumulated precipitation over the past six months (SPI-6), meteorological drought intensities are classified into four categories: concern, caution, alert, and severe. However, there is a limitation in classifying drought intensity solely based on precipitation. To overcome the limitations of the meteorological drought warning criteria based on SPI, this study collected emergency water supply damage data from the National Drought Information Portal (NDIP) to classify drought intensity. Factors of SPI, such as precipitation, and factors used to calculate evapotranspiration, such as temperature and humidity, were indexed using min-max normalization. Coefficients for each factor were determined based on the Genetic Algorithm (GA). The drought intensity based on emergency water supply was used as the dependent variable, and the coefficients of each meteorological factor determined by GA were used as coefficients to derive a new Drought Severity Classification Index (DSCI). After deriving the DSCI, cumulative distribution functions were used to present intensity stage classification boundaries. It is anticipated that using the proposed DSCI in this study will allow for more accurate drought intensity classification than the traditional SPI, supporting decision-making for disaster management personnel.

Melanin is a natural pigment found in most plants and animals, and it is involved in determining the color of the skin and hair. Melanogenesis is a reactive occurrence in melanocytes aiming to protect the skin from external stimuli, such as ultraviolet rays. Tyrosine is involved in the biosynthesis of the substrate tyrosine into melanin. However, melanin overproduction can lead to skin diseases, such as melasma, blotching, hyperpigmentation, and skin cancer. Although many studies have been conducted on whitening substances, such as kojic acid and arbutin, some countries have banned or refrained from using them due to their side effects. Therefore, this study assessed the potential of horseradish (HR) as a new whitening agent in cosmetic products. For efficient extraction, subcritical water extraction was conducted. The results showed that the horseradish subcritical water 200℃ (SW 200) extract showed high DPPH radical scavenging ability, total phenolic contents (TPC), inhibiting tyrosinase activity and inhibiting melanin production of B16-F10 melanoma cell lines. To investigate its cytotoxicity to the B16-F10 melanoma cell lines, MTT reduction assay and morphological changes were observed. No cytotoxicity was found in horseradish methanol extract and SW 200. In conclusion, this research suggests the possibility of horseradish subcritical water may be useful as a natural whitening ingredient to be used in cosmetic products.
