몽골은 현재 국민에 대한 의료 평등이 잘 되어있지 않다. 몽골의 의료 기관은 1,2,3차 기관 세 종류가 있는데 1차는 기본기관, 2,3차는 전문기관이다. 하지만 전문기관은 도시에만 존재하기 때문에 도시권 외 주민들은 전문기관의 의료 서비스를 받기가 매우 힘들다. 게다가 해외 의료 기관들도 모두 수도 울란바토르에 집중되어 있기 때문에 그 격차는 더욱 더 심해진다. 이러한 의료 불평등을 조금이라도 해소하기 위하여 제안하는 것이 'M-LIMS' 이다. 'M-LIMS'는 기본적으로 이동식 병원이다. 'M-LIMS'에서는 환자 진료를 위한 몇 가지 기능을 제공한다. 첫 번째로 환자 관리를 위한 환자용 차트 작성이다. 두 번째로는 환자들의 진료 상황을 볼 수 있는 리스트 검색 및 공유 기능이다. 세 번째로는 환자들의 데이터들을 이용하여 규격화 된 차트로 변환하는 차트 작성 기능이다. 그리고 네 번째로는 차량 내 의사뿐이 아닌 다른 의사도 진료에 참여 할 수 있는 원격 진료 기능이다. 이렇듯 'M-LIMS'의 기능을 이용한다면 몽골의 의료 평등에 한 걸음 더 기여를 할 수 있지 않을까 기대를 한다.

In terms of labor market accomplishments, such as income, size of the company, and the matching quality between one's job and college major (specialization), a very large discrepancy is observed between the graduates from colleges located in Seoul and those outside Seoul. But, when the department average score of the Scholastic Aptitude Test (SAT) at the time of college entrance is controlled for, the discrepancy is found to be reduced to a considerable degree. In the case of wage gap, at least two third can be explained by the SAT score gap. The remaining wage gap seems to reflect the characteristics of workplace. In other words, graduates with high SAT scores enter colleges located in Seoul and thus tend to find better jobs leading to earning differences. This result that confirms the importance of aptitude test scores suggests that in the labor market, one of the major reasons behind a lower accomplishment of the graduate from local colleges is due to a lower competitiveness of local colleges in attracting the brightest students. But, this should not be viewed as only an internal problem of local colleges. This is because the growth of local economies tends to haul the advancement of local colleges in that area rather than being the other way around. The agglomeration effect in Seoul where headquarters of large corporations and financial institutions gather is the factor that has elevated the status of colleges located in Seoul since this provides highly preferred job choices of graduates. When the competitiveness of college is significantly influenced by exogenous factors, such as the vicinity to Seoul, the effort being made by colleges alone would not be enough to improve the situation. However, the central government, too, is not in the position to carry out countermeasure policies for such problems. The regional development strategy boosted through supportive policies for local colleges, such as financial support, is not based on the persuasive and empirical grounds. It is true that college education is universal and that the government''s intervention in assisting local colleges to secure basic conditions, such as tenure faculty and adequate facilities is necessary. However, the way of intervention should not be a support-only type. In order to improve the efficiency and effect of financial support, restructuring programs, including the merger and integration of insolvent colleges, should be underway prior to providing support. In addition, when the policy is focused on education recipients-local college students, and not on education providers-local colleges, the importance of regional gap in compulsory education (elementary and junior high schools) turns out to be much important as the gap between metropolitan area colleges and local colleges. Considering the educational gap before college entrance shown from the discrepancies of aptitude test scores among different regions, the imbalance between regions in terms of human resources is apparently derived from compulsory education, and not from college education. Therefore, there is a need to double the policy efforts to reduce the educational gap among different regions. In addition, given the current situation where it is difficult to find appropriate ex post facto policy measures to solve the problem of income gap between the graduates from metropolitan colleges and local colleges, it can be said that improving the environment for compulsory education in local areas is a growing necessity for bridging the educational gap among different regions.

This study examines changes and educational differences in parental time spent in childcare. Based on time diary data 1999-2009, it finds as follows. First, compared to 1999, parental time spent in childcare has increased in 2009. Unlike the tendency of convergence of time spent in childcare by sex in US, differences by sex have increased in Korea. Second, those who are highly educated tend to spend more time with children than their counterparts. For preschool aged children, parental time spent in physical care and playing has significantly increased by educational level. For school aged children, those who are highly educated are more likely than those who have lower level of education to help with children's study. Third, compared to 1999, time for leisure and economic activity has decreased in 2009 whereas time for commute, sleep, and care for others has increased.

Economic development has resulted in the concentration of population and industry in the metropolitan area. Additionally, the Republic of Korea is experiencing this phenomenon, with more than half of the population living in the Seoul capital area. To alleviate this concentration of population, the Korean government implemented the new town development policy. Unfortunately, this has led to an increase in the commuting population, causing an imbalance in transportation services due to financial and policy differences in each region. This paper analyzes the level of user satisfaction with mega commuting in three aspects: mobility, accessibility, and connectivity. To objectively assess the level of user satisfaction, which is qualitative data, the Rasch Model is used to analyze the collinearity of user data. The results indicate that the level of user satisfaction differs by region, and service satisfaction with mobility is lower than that with accessibility and connectivity. Therefore, prior to the introduction of new town policies, it is necessary to develop metropolitan transportation infrastructure.

Viewed from the framework of world system, international migration is connected sometimes to unequal power relations by prejudice and discrimination in destination areas, or to equal power relations by intentional effort for harmonious multiculturalism. According to the existing ethnic relation theory, assimiationism, it is natural that ethnicity is fading away as the foreign immigrants of different ethnic background have long limed in a destination area, and thus the relative urban ethnic places are weakened and finally dissapeared. Through the various examples particularly on the United States, however, ethnicity would not be easily fading-away but be sustained for long time. Also, the characteristics of ethnicity or ethnic place are sometimes reivented or reconstructed as the various situation of multiculturalism is affected by postmodernism. Whether it is the thing made by ethnic segregation or by ethnic congregation, ethnicity and ethnic place are evidently a kind of affluent resources of culture and economy in the destination areas.

This study examines the labor market performance of graduates who had student loans. Compared to earlier studies, we extended analyses to all jobs that were experienced for more than 18 months after graduation. First, we found that students who had student loans earned 2.81% less at their first job compared to their counterparts without student loans. Second, the wage gap decreased over time, a reduction of 0.66%p due to labor market turnovers. Third, when we compared cumulated labor income, however, the amount for borrowers were continuously higher. This is because the job searching period of a borrower was shorter, despite relatively lower wages at the first job, and borrowers also made more frequent job turnovers, accompanying relatively more wage increases. These results suggest that the negative effects of college loans on earnings, reported in previous studies, may have exaggerated the negative impact to some extent of having loans. However, when we look at the quality of jobs beyond simply wages, the proportion of borrowers working at large companies as regular workers was consistently low. Given that job conditions at the earlier stages of one's career may lead to gaps over time, our findings call for more systematic investigations into the effects that student loans have on long-term labor performance.

In this paper, we analyzed curriculum materials on inequalities as regions. Constructs such as mathematical connections and curriculum articulation were used as a framework. As for articulation, our findings indicate the topic of inequalities as regions addresses meaningful subordinate mathematical thinking and skills that serve prerequisite to calculus. Regarding connections, mathematical concepts involving inequalities extend to multivariate calculus. One implication is, as an unintended consequence of curricular decision of 2015 Revised National Curriculum to teach the topic only in mathematical economics, students who plan to study STEM subjects in college but opt out of mathematics economics in high school may miss the key concept and naturally struggle to understand calculus especially the theory of multivariate function of calculus.

As the memory access time becomes slower relative to the fast processor speed, most systems use cache memory to reduce the gap. The cache performance has an increasingly large impact on the performance of algorithms. Blocking is the well known method to utilize cache and has shown good results in multiplying matrices and search trees like d-heap. But if we use blocking in the data structures which require rotation during insertion or deletion, the execution time increases as the data movements between blocks are necessary. In this paper, we have proposed the extended pairing heap algorithms using block node and shown by experiments that our structure is superior Also in case of using block node, we use less memory space as the number of pointers decreases.

와이파이(Wi-Fi) 기술은 무선 데이터 트래픽 폭증에 따라 사업자에게는 트래픽 우회, 이용자에게는 통신요금 부담 완화의 대안으로 중요성이 부각되고 있다. 이에 우리나라에서는 이동 통신사업자 중심으로 와이파이를 지속적으로 확충하여 세계에서 가장 많은 와이파이 존(zone)을 보유한 국가가 되었다. 그러나, 특정 장소에 와이파이를 중복적으로 구축함에 따라 투자 효율성과 서비스 품질이 저하되고, 서민 소외계층 이용시설에는 구축이 상대적으로 저조하다는 문제점도 상존하는 상황이다. 본 고에서는 우리나라의 와이파이를 효율적으로 확산하고자 3가지 개선방향을 제시하였다. 첫 번째는 경쟁구축 차별화에서 투자효율화 공동이용 전략으로의 전환이며, 두 번째는 수도권 도시 지역 중심에서 서민 소외계층 지역으로 확산시키는 것이다. 마지막으로 Legacy Wi-Fi에서 차세대 Wi-Fi로 전환하는 것을 주요 방향으로 제시하였고, 이러한 개선방향을 바탕으로 4가지 전략을 제시하였다. 첫 번째 전략은 PPP(Public Private Partnership) 방식의 공공와이파이(Public Wi-Fi) 구축으로, 전통시장, 복지시설 등 서민 소외계층이 주로 이용하며 와이파이 구축이 열악한 이용시설에 정부, 지자체, 통신사가 공동으로 투자하여 공공와이파이를 구축함으로써 정보격차를 해소시키는 것이다. 두 번째 전략은 통신사의 와이파이 개방을 통한 공용화로, 통신사가 공공장소에 기 구축한 와이파이의 개방을 유도함으로써 중복투자 및 서비스 품질 저하 방지 등 공용화를 통한 투자효율성을 제고하는 것이다. 세 번째 전략은 차세대 와이파이 선도도입을 통한 글로벌 경쟁력 강화로, LTE 등 이동통신 기술의 급속한 보급에 맞추어 무선랜 서비스의 경쟁력 확보를 위해 광대역화 광역화를 선도하고, 응용서비스 발굴 및 산업활성화를 유도하는 것이다. 마지막은 공공와이파이 인식제고로, 공공와이파이의 이용편의성과 홍보활동을 강화하는 것이다. 이러한 전략의 핵심은 공공와이파이 확산과 차세대 와이파이 선도 도입으로, 이를 통하여 통신복지를 실현하고, 산업활성화를 통한 국민행복을 실현시키는 것에 대하여 간략히 설명한다.

This study analyzed the characteristics of spaces to and from which middle school students transfer, especially centering around the school districts of Southern area in Gyeonggi Province such as Suwon, Osan, Yongin, and Hwaseong. This study was conducted to provide the suggestions regarding educational policies such as the positioning to appropriate school districts, improving of educational environment, and implementing of educational equity, by analyzing, based on the empirical data, the educational spaces of four cities showing rapid population growth due to recent suburbanization. The characteristics of distribution of variables such as schools for each district affecting the student transfer, housing development, and socioeconomics in the research object region are mainly analyzed through the correlation analysis, multiple regression analysis, and cluster analysis. As a result, there is shown a distinct spatial difference between school districts of the cty downtown and urban fringe, and between school districts of the conventional cities(cities that have been from the past: note of translator) and new land development regions. First, the school districts in the city downtown showed lots of transfers between neighboring school districts, while the school districts in the urban fringes showed transfer-out tendencies strongly. Second, it was the new land development regions where the transfer-in rate is the highest in the Southern area of Gyeonggi Province. Third, the said new land development regions required the supply of educational installations and educational support that can meet educational demands, since these regions have relatively lower qualitied educational environments compared to the conventional cities where the fluidity of students is lower. Fourth, in the summary of all of the said three results, the student transfer in the southern area of Gyeonggi Province was shown in the spaces centering around the multi-core area by reflecting the restructuring of suburban area.
