  • A random vector =(X1,…, Xn) is conditionally weakly associated if and only if for every pair of partitions 1=(X$\pi$(k+1),…,X$\pi$(k)), 2=(X$\pi$(k+1),…,X$\pi$(n)) of P(1$\in$A│2$\in$B, $\theta$$\in$I) $\geq$P$\in$A│$\theta$$\in$I whenever A and B are open upper sets and $\pi$ is any permutation of {1,…,n}. In this note we develop some concepts of conditional positive dependence, which are weaker than conditional weak association but stronger than conditional positive orthant dependence, by requiring the above inequality to hold only for some upper sets and applying the arguments in Shaked (1982).

  • Dependence concepts for ordered two-way contingency tables have been of considerable interest. We consider a dependence concept which is less restrictive than likelihood ratio dependence and more restrictive than regression dependence. Maximum likelihood estimation of cell probability under this dependence restriction is studied. The likelihood ratio statistics for and against this dependence are proposed and their large sample distributions are derived. A real data is analyzed to illustrate the estimation and testing procedures.

  • In this paper, we introduce a new notions of conditionally weak dependence and we study their properties, preservation of the conditionally weak independent and positive and negative quadrant dependent(CWQD) property under mixtures, limits, closure under convex combinations, and their interrelationships. Furthermore, we extend multivariate stochastic dependence to stronger conditions of dependence.

  • Objectives: In this study, a multilevel analysis model has been designed to investigate the effect of personal characteristics associated with smoking cessation on anti-smoking determinants with a goal of finding out the factors which have influence on smoking cessation among the entrants of smoking cessation clinic in a public health center. Methods: A total of 253,136 male smokers who received smoking cessation services for more than six(6) months in a smoking cessation clinic of public health center from July 16, 2007 to July 15, 2008 were examined. For technical analysis, SPSS Version 2.0 has been used. For multilevel analysis on smoking cessation determinants, in addition, HLM 7.0 has been adopted. Results: According to the unconditional model of multilevel analysis, the success rates of smoking cessation among the entrants of a smoking cessation clinic were 47.3%. In an unconditional slope model test to which regional variables were added, a negative effect was observed in average smoking amount, total smoking period, nicotine dependence and services while a positive effect was found in age, stress and type of social security in terms of the log of the odds of smoking cessation. In a conditional model test, a positive effect was observed in Non-Smoking Campaigns (NSC) and Frequency of Counseling (FC) in terms of the log of the odds of smoking cessation in regional variables. Conclusions: It is important to approach smokers individually and, at the same time, build healthy environment for a local community to increase smoking cessation rates among the entrants of smoking cessation clinic in a public health center.

  • 본 연구는 다른 국가에 비해 무역개방도가 높은 동아시아 국가의 특징을 고려한 조건부 수렴현상을 패널분석 하였다. 이는 동아시아 국가는 무역개방도가 높은 특징이 나타나고 있기 때문에 경제성장의 수렴현상을 분석하기 위해서는 무역개방도를 추가적으로 통제할 필요가 있기 때문이다. 분석결과 인적자본, 투자율을 통제하였을 때 보다 무역개방도를 추가로 통제하였을 때 수렴현상이 더욱 뚜렷하게 나타났고 수렴속도도 더욱 빨라진 것으로 분석되었다. 추가적으로 동아시아 국가들을 동남아 국가와 동북아 국가로 구분하여 분석하였다. 동북아 국가에서는 절대적 수렴과 조건부수렴 현상이 모두 나타났지만, 동남아 국가에서는 무역개방도를 추가로 통제시킨 조건부 수렴현상만이 나타났다.분석결과를 종합하면 동아시아 국가의 높은 무역개방도를 통제시킨 조건부 수렴에서 수렴현상이 더욱 강하게 나타났다. 본 연구의 분석결과를 바탕으로 시사점을 도출하면 첫째로, 대외무역의존도가 높은 동아시아 국가들의 무역개방도가 경제성장의 수렴에 있어서 상당한 긍정적인 영향을 미쳤다. 둘째, 동아시아 국가의 지역경제통합 성립을 위해서는 동북아시아 국가와 동남아시아 국가의 경제성장 격차를 줄여 나갈 필요성이 있다.
