        유태주의에 대한 중동이슬람 지역의 인식과 대응에 대한 연구

        김중관 명지대학교 인문과학연구소 2007 인문과학연구논총 Vol.28 No.-

        The increasing frequency and severity of anti-Semitic incidents since the start of the 21st century, has compelled the international community to focus on Semitism with renewed vigor. Attacks on individuals and on other countries occurred in the Arab world, but decreased over time and were primarily linked to vandalism and criminal activity. In recent years, incidents have been more targeted in nature with perpetrators appearing to have the specific intent to attack Arabs and Judaism. These attacks have disrupted the sense of safety and well being of Jewish communities. Society and legislation in nations in the region, except for Israel and Lebanon, reflect the views of an overwhelmingly Muslim population and a strong Islamic tradition. At times, both social behavior and legislation discriminated against members of minority religions. Government efforts to limit of reprimand anti-Semitic expressions have been infrequent, and governments in the region generally have made only minima efforts to promote anti-bias and tolerance education, The definition of Semitism has been the focus of innumerable discussions and studies. While there is no universally accepted definition, there is a generally clear understanding of what the term encompasses. For the purpose of that, the paper would survey actual situation in the Middle East countries limitedly.

      • 객체 지향 컴퓨터 시스템의 Method Lookup 캐쉬에 관한 연구

        김병기,김관중,염혜란 崇實大學校 生産技術硏究所 1993 論文集 Vol.23 No.-

        We propose a new method lookup cache for improving the time and the memory efficiency in the object oriented system. The method lookup is a major execution overhead in the object oriented programs. For improving the performance of object oriented program execution, an efficient method lookup mechanism is essential. The static cache, a solution to the method lookup problem, provides a constant time lookup, but consumes excessive memory. Many object oriented system use the coloring scheme that reduces memory size in the static cache. However memory waste still exists in the colored cache. New cache proposed in this paper provides a solution to the memory consumption problem. Moreover it is efficient for solving the multiple inheritance problem that causes memory consumption in the colored cache. Each entry of the new cache consists of method ID and code address fields. Furthermore, the tagging mechanism in this cache enables to perform efficiently the method lookup for methods that have a same name and are defined in different classes.

      • 콘크리트 온도변화 특성에 관한 실험적 연구

        김우중,이원홍,이관희 진주산업대학교 1999 산업과학기술연구소보 Vol.- No.6

        Generally, concrete temperature is risen by hydration at mixture right after, after that falling gradually until the atmospheric temperature. For this temperature falling concrete is contracted. If contraction is restricted externally of internally tensile stress is occurred at concrete. If this tensile stress exceeds tensile strength of concrete tensile crack is occurred at concrete. The rahmen bridge among many bridge type is typical type that is occurred tensile crack at slab. In this paper, the authors investigate how temperature of a rahmen concrete bridge is changed by slab position and the number of days. The experimental results will be applied important crack control data by hydration at concrete.

      • 확장-가중치 버디 기법의 동적 메모리 할당을 위한 주소 지정

        Dynamic memory management has been an important topic in computer systems for over three decades. Especially, object-oriented programming language tend to allocate and deallocate blocks of memory very frequently. The growing popularity of these language increases the importance of high-performance memory allocation. For speed and simplicity in memory allocation, we are choice the extended-weighted buddy system for dynamic memory allocation/deallocation in an object-oriented architecture. In this paper we propose an addressing strategy for high-performance dynamic memory allocation of the extended-weighted buddy system. A modification made feasible by the floating point address can efficient memory allocation/deallocation. Also proposed addressing strategy, modifying floating point addresses to slove the small object problem, and a novel context allocation/access mechanism.

        고지방식이가 백서 골격근 및 지방조직의 지방분해에 미치는 영향

        김철희,정윤이,이성진,박중열,홍성관,김홍규,서교일,이기업 대한당뇨병학회 2002 Diabetes and Metabolism Journal Vol.24 No.6

        연구배경:지방산화의 증가가 골격근에서 인슐린 저항성을 유발한다는 주장이 꾸준히 제기되어 나왔으나, 최근 제2형 당뇨병 환자나 인슐린저항성 상태에서 골격근의 지방산화능이 저하되어 있다는 보고도 있어 논란이 있는 상태이다. 본 연구에서는 고지방식이를 투여하여 인슐린저항성을 유발한 백서에서 microdialysis 기법을 이용하여 조직내의 지방분해 결과로 간질액내로 방출되는 글리세롤 농도를 골격근 및 지방조직에서 직접 측정하여 지방분해의 변화를 알아보고자 하였다. 방법:정상 Sprague­Dawley 백서를 두 군으로 나누어 4주간 고지방식이 및 저지방식이를 투여하였다. 4주간 기저상태 및 고인슐린 정상혈당 클램프 중의 골격근 및 지방조직에 microdialysis probe를 삽입하고 일정한 농도의 글리세롤을 포함하는 dialysate를 통과시켜 주입액과 유출액의 글리세롤 농도 차이로부터 조직 간질의 글리세롤 농도를 산출하엿다. 결과:기저상태에서 골격근 및 지방조직 간질의 글리세롤 농도는 저지방식이군에 비하여 고지방식이군에서 유의하게 낮았다. 고인슐린 정상혈당 클램프 중에는 골격근 및 지방조직 간질의 글리세롤 농도가 양군에서 모두 억제되었는데, 기저 상태와 마찬가지로 골격근 및 지방조직 모두에서 저지방식이군보다 고지방식이 군에서 더 낮았다. 기저 상태에 대한 고인슐린 클램프중의 글리세롤 방출 억제 정도는 저지방식이군에 비하여 고지방식이군에서 덜 억제되는 경향을 보였는데, 골격근조직에서만 통계적으로 유의하였다. 결론:본 연구 결과는 고지방식이에 의한 인슐린저항성 모델에서 골격근 및 지방조직내 지방분해가 억제되어 있음을 보여주며, 기존의 포도당­지방산 cycle 이론과는 달리 조직내 지방산화의 증가보다는 지방산화능의 감소에 따른 세포내 지방축척이 인슐린저항성과 관련될 가능성을 시사하였다. Background : It has been hypothesized that increased fat oxidation reduces glucose utilization in skeletal muscle, and is responsible for the insulin resistance associated with obesity or high-fat feeding. In contrast, there have been reports that fat oxidation capacity was decreased in skeletal muscles from insulin resistant subjects. This study was undertaken to examine whether insulin resistance in high-fat fed rats is associated with increased lipolysis in skeletal muscle and adipose tissue. Methods : Two groups of Sprague-Dawley rats were fed either high-fat or low-fat diets for 4 weeks. Lipolysis in skeletal muscle and adipose tissue was determined by measurement of interstitial 1 glycerol concentrations by a microdialysis method in basal and hyperinsuline mic-euglycemic clamp conditions. Results : In basal state, plasma glycerol levels and interstitial glycerol concentrations of skeletal muscle, and adipose tissue were lower in high-fat fed than in low-fat fed rats. The degree of suppression of glycerol release by the hyperinsuline mia was smaller in the high-fat diet than in the low-fat diet group. However, plasma and interstitial glycerol concentrations during the hyperinsuline mic euglycemic clamps were also lower in the high-fat diet group. Conclusion : Lipolysis was decreased in skeletal muscle and adipose tissue of insulin resistant, high-fat fed rats. These results support the idea that limited fat oxidation capacity resulting in lipid accumulation in tissues, rather than increased fat oxidation perse, is responsible for the insulin resistance associated with high-fat feeding (J Kor Diabetes Asso 24:641~651, 2000).

      • 직접강도법에 의한 축대칭 원추형 쉘의 단순화 해석

        김우중,권중현,이관희 진주산업대학교 1997 論文集 Vol.36 No.-

        The stress analysis concerned with axisymmetrically loaded axisymmetrical structures, such as pressure vessels, rockets, cooling towers, roof domes and storage tanks, has been researched with a lot of difficulties. The elements of revolution using the finite element method enable these problems to be analyzed with a high degree of confidence. This research focuses on the efficient conduct of the thin axisymmetric shells subject to axisymmetrical load which was idealized by a series of conical frustum-shaped elements that was suggested by Grafton and Strome and later extended by Percy. In this study, this research mentioned above is extended to the conical shell whose end is fixed to simplify the methodology of the analysis of any kinds of axisymmetrically loaded axisymmetrical shell structures. To demonstrate the validity and simplicity, the results of the proposed method were compared with the numerical solution SAP90 and got agreeable results.
