The purpose of this paper is to prepare the department creation and the staff increase of education institution by forecasting the demand of health and welfare workers according to execution of the elderly's long-terms treatment insurance system in July, 2008. We estimated confirmors of the elderly's long-terms treatment and the demand of professional workers of health and welfare field due to the increase of care insurance users in facilities treatment organization, care at home service facilities, and family allowance facilities for 2010-2030. The numbers of social welfare professional worker are estimated as 16,624 workers in 2020 and 24,688 workers in 2030. The numbers of nurses are forecasted as 11.287 in 2020 and 16,624 in 2030, we expect that the increase of the demand be accelerated. The demand of necessary care probation worker is 44,824 in 2009, but we already trained over around 500,000 workers in 1,078 education institutions through one year in Aug. 31, 2009, which excesses over the numbers of workers demanded as much as 10 times.

Prefetch R-tree: 디스크와 CPU 캐시에 최적화된 다차원 색인 구조

박명선,Park Myung-Sun 한국정보처리학회 2006 정보처리학회논문지D Vol.13 No.4

R-tree는 일반적으로 트리 노드의 크기를 디스크 페이지의 크기와 같게 함으로써 I/O 성능이 최적화 되도록 구현한다. 최근에는 주메모리 환경에서 CPU 캐시 성능을 최적화하는 R-tree의 변형이 개발되었다. 이는 노드의 크기를 캐시 라인 크기의 수 배로 하고 MBR에 저장되는 키를 압축하여 노드 하나에 더 많은 엔트리를 저장함으로써 성능을 높였다. 그러나, 디스크 최적 R-tree와 캐시 최적 R-tree의 노드 크기 사이에는 수십-수백 바이트와 수-수십 킬로바이트라는 큰 차이가 있으므로, I/O 최적 R-tree는 캐시 성능이 나쁘고 캐시 최적 R-tree는 디스크 I/O 성능이 나쁜 문제점을 가지고 있다. 이 논문에서는 CPU 캐시와 디스크 I/O에 모두 최적인 R-tree, PR-tree를 제안한다. 캐시 성능을 위해 PR-tree 노드의 크기를 캐시 라인 크기보다 크게 만든 다음 CPU의 선반입(prefetch) 명령어를 이용하여 캐시 실패 횟수를 줄이고, 트리 노드를 디스크 페이지에 낭비가 적도록 배치함으로써 디스크 I/O 성능도 향상시킨다. 또한, 이 논문에서는 PR-tree에서 검색 연산을 수행하는데 드는 캐시 실패 비용을 계산하는 분석 방법을 제시하고, 최적의 캐시와 I/O 성능을 보이는 PR-tree를 구성하기 위해, 가능한 크기의 내부 단말 노드, 중간 노드를 갖는 PR-tree 생성하여 성능을 비교하였다. PR-tree는 디스크 최적 R-tree보다 삽입 연산은 3.5에서 15.1배, 삭제 연산은 6.5에서 15.1배, 범위 질의는 1.3에서 1.9배, k-최근접 질의는 2.7에서 9.7배의 캐시 성능 향상이 있었다. 모든 실험에서 매우 작은 I/O 성능 저하만을 보였다. R-trees have been traditionally optimized for the I/O performance with the disk page as the tree node. Recently, researchers have proposed cache-conscious variations of R-trees optimized for the CPU cache performance in main memory environments, where the node size is several cache lines wide and more entries are packed in a node by compressing MBR keys. However, because there is a big difference between the node sizes of two types of R-trees, disk-optimized R-trees show poor cache performance while cache-optimized R-trees exhibit poor disk performance. In this paper, we propose a cache and disk optimized R-tree, called the PR-tree (Prefetching R-tree). For the cache performance, the node size of the PR-tree is wider than a cache line, and the prefetch instruction is used to reduce the number of cache misses. For the I/O performance, the nodes of the PR-tree are fitted into one disk page. We represent the detailed analysis of cache misses for range queries, and enumerate all the reasonable in-page leaf and nonleaf node sizes, and heights of in-page trees to figure out tree parameters for best cache and I/O performance. The PR-tree that we propose achieves better cache performance than the disk-optimized R-tree: a factor of 3.5-15.1 improvement for one-by-one insertions, 6.5-15.1 improvement for deletions, 1.3-1.9 improvement for range queries, and 2.7-9.7 improvement for k-nearest neighbor queries. All experimental results do not show notable declines of the I/O performance.

독일 이민법과 통합정책의 외국인 차별에 관한 연구

박명선(Park Myung Sun) 한국사회학회 2007 韓國社會學 Vol.41 No.2

2005년부터 발효된 독일 이민법은 독일이 이민국임을 인정하며 오랜 기간 지속해 온 이주정책을 획기적으로 전환할 것으로 주목받고 있다. 인구감소와 복지국가 축소의 위기, 지구화시대의 경쟁체제 상황에서 부족한 전문인력 도입의 불가피성은 이주민들의 통합과 국적 취득을 더이상 미룰 수 없게 한 배경이다. 이민법에 의해 새롭게 조직된 통합정책은 ‘지원과 요구’의 원칙에 따라 국가가 이주민들에게 언어강좌를 제공하는 한편, 이주민들은 언어습득의 의무를 이행하도록 하였다. 또한 언어시험을 실시하여 그 성과를 평가, 체류허가의 조건이 되게 하였다. 이를 통해 수용국이 원하는 이주민을 선발하고, 원하지 않는 이주민을 배제할 수 있는 근거를 갖추게 된 것이다. 이러한 경향은 유럽연합의 이민통합정책을 근거로 최근에 이주민 통합정책을 재조정한 네덜란드, 오스트리아, 프랑스에서도 공통적으로 나타난다. 지구화시대 세계시민권을 주장하며 다문화주의사회 발전을 지향하던 지성사의 흐름은 활발한 국제이주의 문제에 대한 ‘통합’이라는 명목의 정책 개입을 가능하게 했다. 그러나 21세기 들어 급격하게 반테러주의와 반이슬람주의로 반전된 분위기는 이주민의 동화 또는 배제를 통합정책의 목적으로 정당화시키고 있다. 독일의 이민법과 통합정책은 인종차별적 강제징용과 외국인노동자 귀국 촉진 등의 이주정책 역사를 바꾸기 위한 일정한 전환의 계기를 마련하기는 했지만 여전히 이주민에 대한 민족차별적인 지속성을 보이고 있다. The new German immigration law that took effect in 2005 officially certifies Germany as an immigration state. This change is regarded as the turn point of Germany’s year-long immigration policy. The threat of reduction in German population and the moderation of state welfare policies, and the lack of professionals and experts of IT-field in today’s competitive system of globalization urged the German government to ease the integration of immigrants and their attainment of citizenship. According to the principles of ‘support and demand’, the newly organized integration policy set by the immigration law requires the government to offer a German language course and for the immigrants to uphold the duty of learning the language. The conditions of residence permit are determined by the outcome of the final language test that the immigrants receive. Through these programs, the host country can segregate the useful immigrants from the other useless immigrants for its own interest. This trend appears commonly in Netherlands, Austria, and France, who have also reformed their integration policies in the grounds of the EU immigrant integration policy. The political intervention for the active international immigration could be accelerated in the name of ‘integration’ by the flow of intellectualism, that maintained the world citizenship in the epoch of globalization and aimed at the development of plural societies. But the sudden turn of the atmosphere to anti-terrorism and anti-islamism is justifying the degeneration of the integration policy goal and the assimilation and exclusion of the immigrants. Although the new German immigration law and integration policy seeks to change the German history of racist requisition and the amount of returning foreign laborers to their native lands, the ethnical discrimination of immigrants is continued yet.

아동의 스트레스 및 자아탄력성과 학교생활적응간의 관계

박명선(Park, Myung Sun),유가효(Yoo, Ka Hyo) 계명대학교 생활과학연구소 2013 과학논집 Vol.39 No.-

The purpose of this study in to investigate the relationship among the child’s stress, ego-resilience, and school life adaptation by sampling 324 students, every two class of the 5th/6th grade of 3 elementary schools in Daegu city. The program of SPSS 18.0 was used to analyze the collected data. The results are as follows. First, the child’s stress makes no difference by the gender and the school grade but does according to the living standard. The child’s stress of upper class in higher than that of lower class. However, ego-resilience has no difference according to the gender, classes and living standard. Second, the relationship between child’s stress and his(her) ego-resilience shows negative correlation, as a child has better ego-resilience, he or she experiences less stress. Third, there is the negative correlation between stress of a child and his(her) school life adaptation. As a child experiences less stress, he or she does better school life adaptation. Fourth, there is the positive correlation between child’s ego-resilience and his(her) school life adaptation. Particularly, as a child has better personal relationship and higher optimism, he or she responds better friendship adaptation. And, as a child has better emotional control and more curiosity, he or she does better adaptation to teachers. Fifth, In the regression analysis of the effects of sex, standard of living, stress and ego-resilience of a child onto his(her) school life adaptation, it reveals that the significantly effective sub-factors of child’s stress and ego-resilience onto his or her school life adaptation are emotional control/curiosity, personal relationship/optimism and stress from teacher in order. The result shows the effect of child’s ego-resilience onto school life adaptation is larger than that of stress of child. In other words, it suggests that child’s ego-resilience has buffering effects to reduce the influence of stress on child’s school life adaptation.

박명선(Myung Sun Park),이용구(Young Koo Lee),김학철(Hak Cheol Kim) 대한내과학회 1994 대한내과학회지 Vol.47 No.1

Objectives: The acute hepatitis due to hepatitis E virus is known as an water-borne disease. Its clinical manifestations are similar to hepatitis A virus. when pregnant women are contracted, the mortality rate reaches up to 20 percent. We evaluated the characteristics of anti-HEV IgG as a useful epidemiological tools. Methods: An epidemioiogical study was done to detect anti-HEV IgG by ELISA method with anti-H.EV IgG kit (Diagnostics biotechnology Ltd Singapore), and serum globulin by Biuret kit (Abott®, USA) and immunoglobulin G by radio-immuno-diffusion test kit (Nissui Co, Japan) from the randomly collected 470 sera collected from our ward patients in Wonkwang Uvinersity hospital. Results: 1) The mean prevalence rate of anti-HEV was 9.89%. 2) The prevalence rate of anti-HEV was significantly higher in group with history of traveling abroad (especially to south-east Asia) and those who drank tap water; their mean prevalence rate was 33.3%(60%) and 27.8% respctively. [p< 0.01 (p< 0.05) p<0.01]. 3) The prevalence rate of anti-HEV was higher in the urban area than in the rural area (p<0.01). 4) The prevalence rate of anti-HEV was related to the interval since of the traveling abroad and it's titer was also significantly related to period of the traveling abroad (both p<0.01), And also it's titer gradually decline with the lapse of time to traveling abroad among travellers whos was positive for anti-HEV (R=0.903, p < 0.05). Conclusions: It is suggested that HEV infection may occur sporadically in the north-west area of chollabuk-Ko, but traveling abroad, especially hyginically unappreciated area, and drinking tap water may induce more prevalence. With the lapse of time, the titer of Anti- HEV IgG would gradually decline and anti-HEV body not plssist as anti-HAV or anti-HBs.
