THE RELATIONSHIP BETWEEN SHORT-RANGE MOVES AND LONG-RANGE MOVES

정경택,정동호 동양대학교 산업기술연구소 2001 東洋大學校 産業技術硏究所 論文集 Vol.3 No.1

We study the relationship between short-range moves and long-range moves by considering the first bifurcation point of r as a function of m in the game of life type automata network which is the two-dimensional probabilistic automata network model whose rule consists of two subrules. The first subrule, applied synchronously, is a local transition rule of nonzero sites characterized by the interaction with a neighborhood. The second one, applied sequentially, describes the motion of nonzero sites. The second subrule has been used to model complex systems when the movement of nonzero sites plays an important role. A new parameter r is introduced to represent the rare of long-range moves. When r is equal to zero or one, the motion of the nonzero sites is, respectively, purely short-range or purely long-range. In the game of life type automata network, as r increases, the stationary density of nonzero sites follows a route to chaos through the familiar cascade of period-doubling bifurcations. The first bifurcation point of r changes with m. Both limits of r, r → 0 and r → 1, gives the m for the purely short-range moves and the purely long-range move. The models of both range moves shows the same physical nature.

ATM 스위치의 폭주 제어 및 최대 링크 이용률을 위한 대역 할당 알고리즘

정경택 한국통신학회 2000 韓國通信學會論文誌 Vol.25 No.11

ATM 스위치에서 입력 트래픽의 링크 이용의 불확실성과 입력 트래픽에 대한 예측 오류 등으로 인한 폭주가 발생될 가능성을 완전히 배제할 수 없기 때문에 스위치내부에서 폭주 발생을 억제할 수 있는 방법이모새되어야 한다.본 논문에서는 스위치 내부 링크의 대역 사용량을 측정하여 폭주 및 트래픽 제어를 수행하고 링크 이용률을 최대화하기 위한대역 할당 알고리즘을 제안한다. 폭주가 발생한 링크에 대하여 짧은 시간 내에 폭주를 해결하고 폭주가 발생하지 않은 링크에서는 사용하고 남은 여분의 대역을 공평하게 할당함으로서 링크의 이용률을 극대화할 수 있으므로 트래픽 관리를 보다 쉽고 효율적으로 수행할 수 있다.

포스트소비에트 공간에서의 민족-언어분규 연구

정경택 한국러시아문학회 2019 러시아어문학 연구논집 Vol.64 No.-

This article aims to examine the possibility of conflicts and disputes between titular nations and ethnic minority groups in the post Soviet countries where most of the policies were designed only for the titular nations. Most of the Post-Soviet countries supported a policy that a language of the indigenous national must be used as a lingua franca. This caused the resistance of minority people in the countries. Especially, the promotion of the language status and function as an indigenous national language resulted in discrimination in the political, economic and socio-cultural areas of the ethnic minorities. In the 14 new independent countries except for the Russian Federation, the Russians became an ethnic minority. It led Russian peoples to emigrate out of the new independent country, creating a chaotic situation. In the Baltic region, Russians have descended to ethnic minorities, and the use of Russian language has also been banned. Thus there is a possibility of a conflict between the titular nations and Russians. The ethnic minorities in Moldova are also Russians, who constitute a de facto independent state, Transnistria. Another ethnic minority, the Gagauzes, compromised with the Moldovan government and formed a self-governing organization in the territory of Moldova. However, there is a possibility of a conflict between the titular nations and Gagauzes. Ethnic minorities in the Caucasus region are the Abkhazians, Ossetians of Georgia, the Russians and Azerbaijani of Armenia, and the Russians and Armenians of Azerbaijan. The status of the Russians and Russian language in Armenia and Azerbaijan remains virtually unchanged, but the Russian-speaking regions of Abkhazia and South Ossetia in Georgia are still likely to experience ethnic and language disputes. Minorities in Central Asia are the Karakalpaks and Tajiks in Uzbekistan, and the Uzbeks in Kyrgyzstan (mostly in Osh Province) as well as the Russians and Koreans, who were Russian single language users and became ethnic minorities in the new environment.

The purpose of the study were to explain the difference from adolescent gender and parents' academic career, social and financial level and to figure out difference of aggressiveness. The adolescent identify was what affected the difference from perceived social support and aggressivenss, stress perception level and aggressiveness, and social support and perceived stress. In order to examine of the study, it was surveyed by 400 students, from first to third grade, T Men's Senior High school, and 250 students, first to third grade, from K Women's Senior High School were both located in the city of Daegu. A questionnaire was used to measure the social support scale, stress level, aggressiveness. The survey are analyzed with SPSS 10.0 for window statistics package. There were some conclusions resulting from the examination. First conclusion: Girls have a higher sense of aggressiveness then boys according to adolescent gender. Second conclusion: They have a lower aggressiveness if their parents have high academic career. Third conclusion: There is no difference due to their life standard. Forth conclusion: A lower aggressiveness is showen when the perception standard of the students is high, at the adolescent perceiving social support. Sixth conclusion: Explanation of a variation is due to school life, influence of environment, home life, and social support of friends.

Ingushes are indigenous peoples of the North Caucas and they have their own ethnic identity and language, but were merged into the Russian Empire in 1770. In 1924, it was formed as a Ingushetia Autonomous Oblast’, but due to Soviet artificial boundaries, it merged with Chechnya in 1934 to become a Joint Autonomous Oblast’ and in 1936 a Joint Autonomous Republic, which was virtually absorbed into the Chechens. During the Soviet period of 1944-1957, they were forced to move to Central Asia for 13 years and artificially integrated with the Chechens and were in danger of losing his identity and language. In June 1992, he finally gained the status of an indigenous people who constituted the Republic of Ingushetia. Ingushetia has decided to define Ingush language as state language through the Constitution and the Law on State languages, and is promoting its preservation and development, but it is in a situation where it may lose its ethnicity and language due to the increasingly strengthening Russian assimilation policy. This situation is equivalent to almost all national republics in the Russian Federation, but the size of the territory and population shows that the risk is greater than any other republic.

Intensification of import restriction imposed by advanced countries based on protectionism, pressures to open domestic markets, and shortened product life cycle prusuant to accelerated technology innovation, demannd strengthening of international competitiveness through technology and quality rather than through prices which have hitherto been export foundation for Korean enterprises. Such environmental changes are expected to seriously affect enterprises regardless of business sizes, requiring small-medium enterprises, in particular, to flexibly cope with environmental changes : and further require managers of small-medium exterprises to intentionally maintain strategic ideas in order to realize structural improvement and growth. Small-medium enterprises of Korea, however, are too restricted structurally, in terms of human and material resources, to effectively compete under these environmental changes, and it is expected that management of small-medium enterprises will face intensified difficulities. Furthermore, the recent world economic environment changes are too serious for small-medium enterprises of Korea to simply have an easy attitude of waiting for epoch-making economic policies to be established by Government. Accordingly, these studies attempt to discuss directions the small-medium companies of Korea should take under such changes of world economic order, and right directions and courses for Korean economy to take to satisfy the requirements of globalization. In other words, this research seeks to examine the necessity for Korean small-medium enterprises to pursue globalization strategies, and at the same time, analyze actual situation and problems currently facing Korean small-medium enterprises to determine desirable globalization sterategies small-medium enterprises should take. The scope of this studies, therefore, are concentrated on small-medium enterprises which occupy considerable weight in Korean economy rather than on large business groups, with an aim to discuss the subjects of globalization, and strategic management for small-medium enterrises. These studies offer a general definition on globalization through literature examination, based on which subject areas of globalization for Korean small-medium enterprises are to be determined. In addition, this research presents the necessity for Korean small-medium enterprises to pursue globalization strategies with respect to internal and external effect of national economy. Through status analysis carried out for entire small-medium enterprises, degree of globalization effected in the past by Korean small-medium enterprises will be examined; and, in addition, conceptional frame aimed at analyzing current situation facing small-medium enterprises will be developed through the use of international competitiveness appraisal model, and problems facing small-medium enterprises with respect to human and material resources brought to surface. In conclusion, this research attempted to develope globalization strategy model of Korean small-medium enterprises based on problems analyzed, and present, though this model, desirable globalization strategies that small-medium enterprises should pursue. In addition, in order to effectively analyze literatures and materials tobe used for these studies, domestic and foreign books and literatures, and secondary materials related to small-medium enterprises, will be utilized widely.

ATM ABR의 공평성들을 위한 새로운 스케쥴링 알고리즘

정경택,박준성,박현,전병실,Chung, Kyung-Taek,Park, Jun-Seong,Park, Hyun,Chon, Byoung-Sil 대한전자공학회 2002 電子工學會論文誌-TC (Telecommunications) Vol.39 No.4

The WRR scheduling algorithm is widely used in ATM networks due to its simplicity and the low cost of hardware implementation. It guarantees minimum cell rate according to the weight of each queue. The fairness is a important factor for ABR service. That is, scheduling algorithm allocates network resources fairly to each VC. However, WRR algorithm shows worse performance on bursty traffic. Because it schedules input traffics according to predetermined weight, it can not satisfies fairness criteria, MCR plus equal share and Maximum of MCR or Max-Min share, defined by ATM Forum TM 4.1 specification. The Nabeshima et al algorithm is not adapt to network status rapidly because it is not compensate the weights of unused bandwidth to VCs and assign the unused bandwidth to VCs by RR method. In this paper, we propose a scheduling algorithm for satisfying the two fairness criteria, MCR plus equal share and Maximum of MCR or Max-Min share, among the six criteria defined by ATM Forum TM 4.1 specification. The WRR, Nabeshima et al, and the proposed scheduling algorithms are compared with respect to fairness and convergence time throughout experimental simulation. According to the simulation results, the proposed algorithm shows higher fairness and more rapid convergence than other algorithms.
