The National Aeronautics and Space Administration (NASA) has long been studying the essential elements of manned planetary exploration and has held several international challenges to encourage the research works related to it. One of them was the NASA Centennial Challenge Programs which started in 2015. Following the second in 2017, the third is currently going on in 2019. Participating "3D-Printed Habitat Challenge", one of the challenges in the second program, this research team designed and developed the 3D printer extruding module for the Lunar Simulant (Korea Hanyang Lunar Simulant-1; KOHLS-1) and the polymer. For optimizing the modul, a cylindrical specimen of ${\varnothing}150{\times}300mm^3$ volume and a specimen of $200{\times}100{\times}650mm^3$ volume were manufactured and their compressive and flexural strengths were tested. The findings can help automatize the space construction in the future.

Sweden invited immigrant workers, mainly from Nordic countries and West European countries until the 1960s. But since the 1970s refugees and their family members have become the largest group of immigrants. As the composition of immigrants has changed significantly, and the labor market conditions have been aggravated, immigrants have had much difficulty in finding jobs. This has aroused policy debates concerning the reason why the immigrants are not well integrated into the labor market and how to solve the problem. While there is a broad consensus on micro reform policy alternatives, there are significant opinion gaps concerning major issues such as labor market flexibilization and immigration restrictions. It would seems that the poor results of immigrants' labor market integration may increase the pressure for labor market flexibilization and also bring about significant changes to the Swedish welfare state model designed on the premise of full employment.

With increasing international labour in Korea, the perspective of foreign workers' maintenance and changes of origin while living and working overseas provides a new angle for leadership research. For the purpose to investigate the effect of leadership on the group of foreign workers, this study targeted Filipino workers in U and G city and explored whether authentic leadership predicts foreign workers' work engagement and retainment through the potential intervening effect of interpersonal trust. The empirical study utilized SPSS, and results proved that authentic leadership has no significant relationship to foreign Filipino workers' work engagement directly, but authentic leadership showed a negative effect on Filipino workers' turnover intention. The full mediation effect of interpersonal trust proves the value and importance of establishing trust relationships in retaining foreign workers.

The diversity of urban landscapes is established by dynamic characteristics such as language, color, and their movement, which are the building environment, street patterns, and people. With the increase of foreign migrants in Korea, new guidelines are needed in terms of local community administration and land policy. Administrative, sociological, and geographical studies have been conducted on the steadily increasing number of foreign migrants since the 2000s, but it is difficult to establish for making safe and healthy communities through which different cultures and lifestyles of each country and ethnic group undergo some integration with the existing host society. There are limitations in identifying the lack of statistical data and the representation of a minority proportion of foreign residents. In order to analyze the core elements of the integrated strategy of the local community, the residential behavior and spatial characteristics of foreign migrants must first be identified.

Purpose: The purpose of this paper is to examine the recently rising number of foreign drug offenders in Korea and suggest improvement measures for the Korean drug policy. Method: This paper analyzed the preceding research, statistical data, etc., on related fields and referred to overseas cases to suggest improvement measures. Result: The foreign population living in Korea increased in 2000s, and the foreign drug offender cases are increasing accordingly. The survey on foreign drug offenses showed that the case of foreign drug offender is higher than the case of Korean drug offenders by 1.2 to 3.3 times. In 2021, the foreign drug offender cases increased by 6.5 times compared to 2012. Especially, the number of psychoactive drug-related drug offenses increased dramatically. The drug smuggling also remarkably increased starting from 2016 as some people earned a lot of money from smuggling the drugs Conclusion: To cope with the foreign drug offenders effectively, this paper suggested intensive monitoring of the foreign drug offenders and weighting on the drug offenders depending on their home country to intensify the entry standards on foreigners who are likely to smuggle drugs.

In recent years, lots of studies on the planetary rover systems have been performed around space advanced agencies such as NASA, ESA, JAXA, etc. Among the various technologies for the planetary rover system, the mobility system, navigation algorithm, and scientific payload have been focused particularly. In this paper, the conceptual design for a ground-based model of planetary rover's mobility system to evaluate mobility and moving stability on ground is presented. The status of overseas research and development of the planetary rover systems is also addressed in terms of technical issues. And then, the requirements of the planetary rover's mobility system are derived by means of considering mobility and stability. The designed rover's mobility system has an active suspension with 6 legs that controls 6 joints on the each leg in order to achieve high stability and mobility. This kind of mobility system has already applied to the ATHELE of NASA for various purposes such as transportation and habitation for human lunar exploration activities in the near future (i.e., Constellation program). However, the proposed system has been designed by focusing on the small-sized unmanned explorations, which may be applied for the future Korea Lunar exploration missions. Therefore, we expect that this study will be an useful reference and experience in order to develop the planetary exploration rover system in Korea.

This study was conducted to derive a positioning map using multidimensional scaling method to understand how the brand image of national foods including Korean food, Chinese food, Japanese food, Thai food, and Vietnamese food is perceived by domestic and foreign tourists. In order to achieve the research purpose, this study collected 250 data through online and offline surveys for potential food tourists who are interested in visiting overseas. Except the unfaithful responses or missing values, 202 data were analyzed. As a result, first, 8 factors which are considered to be important by food tourists were extracted. Second, the result of similarity analysis using ALSCAL and PROXSCAL did not show that the foods of the five countries were very similar, but all countries seemed to be more likely to compete with each other. Third, attribute selection also indicates that mean value of food taste (3.88), national image (3.82), and sufficient food quantity (3.65) had high level of importance, respectively. These results may provide practical implications for development of branding strategy in food tourism.

This paper explores micro-contexts of transnational migration and decision-making process of foreign migrants in Korea with four types, that is, married immigrants, immigrant workers, professional immigrants, and foreign students, analyzing dates of questionaries and interviews. Some findings can be summarized as follows. First, married immigrants and immigrant workers show relative lower level of micro-environments than professional immigrants and foreign students. Secondly, immigrants workers fill closest in geographical contiguity among immigrants' types, while married immigrants recognize more different in cultural comparison than the former. Both immigrants workers and foreign students think living environments of Korea better than other types, but immigrants workers consider relatively higher the level of technology, while foreign students evaluate lower that of education in Korea than other types. Thirdly, married immigrants give a relatively low score to the easiness of immigration, while both immigrant workers and professional immigrants give a high score to the job environment of Korea. Finally, all types of immigrants show a high portion in a self-decision making for international migration, while professional immigrants have much more experiences on visiting other countries than other types, and both married immigrants and foreign students seem to have utilized their networks with family members who live abroad.

Malaria is estimated to have a worldwide incidence of more than 100 million clinical cases and approximately 1 miuion deaths per year. Korea, although previously tnlown as an endemic area of tertian malaria (Pzosmonin vivax), has been considered free from malaria as there had been no report on indigenous cases since 1984. Recently, however, we experienced an indigenous case of P. viuax infection in a young man who had never been abroad. The patient was a 23-year-old Korean soldier with 18-day history of recurrent fever and chill lasting 4 to 8 hours on alternative days since mid-July 1993. He had lived in Changwon, Hyongsangnam-do, before entering barracks located in Paiu-gun, Kyonggj-do on Jne 1992, and had never been out of Korea. He had no history of blood transfusion nor parenteral use of drugs. The peripheral blood smears showed typical ring forms, trophozoites, and gametocytes of p. uiuox, in addition to mild anemia and thrombocytopenia. After confirmation of the diagnosis, he was treated with hydroxychloroquine and primaquine. Follow-up blood smears no more revealed malaria parasites. It is not certain whether the present case is due to a resurgence of indigenous malaria or a secondary infection from introduced mnuia. Whichever the source of infection the domestic occurrence of mnuia cycle in Korea should be a warning sign in public health point of view.

During the pandemic status of COVID-19 since 2019 December, demands and attention on various convergence services with non-contact technologies and social adoption are increasing. Along with these increased demands and attention, the digital divide issues should be concerned to understand the informatization degrees of rural area residences, the elderly, the disabled, and the low-income. Furthermore, rural area residences may be the elderly, the disabled, and the low-income also. It may mean that the rural area should be considered as in noticeable status of the digital divide. This study focuses on the policy alternatives to reduce the digital divide in rural areas with a literature review methodology and on the factors on informatization issues in rural areas. For the aims, this study analyzes the EU cases of informatization in rural areas to find out the advantages and disadvantages of the suggested policies. As the analysis result, it is clear that the EU countries try to enhance the economic and growth powers rather to reduce the digital divide gaps. Also, it can be considered that the EU countries focus on supporting the rural area to adopt the non-contact information services newly rather on maintaining the IT education services and the infrastructures in off-line environments.
