It may be meaningful that analysis of possible continuity and change of North Korea's Kim Jong-un's ruling in its third year. For this analysis, for the application more rational and statistical analysis methods, this study takes advantage of the new years' messages of Kim Il Sung, Kim Jong Il, and Kim Jong-un. In North Korea, the new years' messages are rare enough to give influence to every field of the North Korea's community and the New Year's message performs tutorial role throughout the whole year. The said messages of Il Sung, Kim Jong Il, and Kim Jong-un regimes have been researched and comprehensively summarized. The summarized New Year's Message by Kim Il Sung, Kim Jong Il, and Kim Jong Un are separated, compared and analyzed by the regime by presentation method, configured information, and others followed by New Year message's characteristics and implications of each North Korean regime that have been investigated. Based on the results of this analysis of Kim Jong-un era, possibility of its continuation and change is forecasted. Above all, for possible continuation of the ruling, sticking to the governing socialist way and military-first politics are presented. For possible causes of change, such the four factors as partial opening to overcome economic problems, the North Korean nuclear issue, influx of the nature of capitalism, and Kim Jung-un's control weakness have been presented. Such the factors of possible change and continuation of the North Korea Kim Jung-un ruling are expected to work as a combination of factors. The issue of continuation and change of North Korea Kim Jong-un's control is a key point for us to solve the issues between North and South Koreas. In the situation that the whole people of South Korea have a national consensus in the effort of gathering the public opinion, it is a high time that we needed to have much flexibility to actively cope with the North Korean issues.

Over the last 70 years, South Korea has gone through countless provocations from North Korea. Provocation is something that must be delicately calculated before the actual action, since it can be extended to a serious conflict. Among the possible factors, this paper focuses on the leader's characteristic, because 1) under North Korean dictatorship, the leader's thoughts are critical influence to policies and 2) personal characteristic, especially if it is the dictator's, hardly changes even when the external circumstances change. The purpose of this paper is in analyzing the correlations between North Korean leader's characteristics and provocation pattern. First, three generations of Kim Il-sung, Kim Jong-il, and Kim Jong-un's personal characteristics will be described. Next, particular provocation features in respective leader's period will follow. Lastly, how each leader's characteristic and concerns were reflected on the provocations will be analyzed.

This research scrutinizes the concept of 'Juchegeonchuk' (self-reliance ideology in architecture), which is a key concept to understand the architecture and urbanism of North Korea in the 1970's and 80's. In the 1970's and 80's, Kim Jong-il began to appear in politics in earnest after Kim Il-sung appointed Kim Jong-il as Kim Il-sung's successor to the next generation. There have been many previous studies about 'Juchesasang' (self-reliance ideology) in various fields, except in architecture. On the other hand, the in-depth research into Juchegeonchuk, which was a method to strengthen Juchesasang, was not good enough in architecture. In this sense, this research investigates the concept of Juchegeonchuk based on the Geonchugyesullon (The Art of Architecture), which embodied the thought of architecture and culture of Kim Jong-il published in 1992. This research scrutinizes the idea of Juchegeonchuk on The Art of Architecture, and its representation in architecture and urbanism in Pyeongyang based on the idea of Juchegeonchuk. It enables to find a new interpretation of North Korea's architecture introduced by Kim, Jong-il in the late 20th century.

Anthrax lethal toxin, which consists of two separate protein, protective antigen (83 KDa) and lethal factor (85 KDa) is responsible for major symptoms and death from systemic infection of Bacillus anthracis. High concentrations of this toxin are cytolytic to macrophages, whereas sublytic concentrations of lethal toxin induce these cells to produce interleukin $1{\beta}$ ($IL-1{\beta}$). It is proposed that melatonin and dehydroepiandrosterone (DHEA) may play an important role in modifying immune dysfunction. In this study, we investigated whether or not melatonin and DHEA could prevent $IL-1{\beta}$ production that is induced by anthrax lethal toxin in mouse peritoneal macrophages. Treatment of melatonin or DHEA alone, as well as together, prevented the production of $IL-1{\beta}$ caused by anthrax lethal toxin. We found that melatonin at a concentration of $10^{-6}-10^{-7}$ M inhibits $IL-1{\beta}$ production induced by anthrax lethal toxin. As expect, treatment of DHEA at a concentration $10^{-6}-10^{-7}$ M also suppressed production of $IL-1{\beta}$ by lethal toxin stimulated macrophages. The results of these studies suggest that melatonin and DHEA, immunomodulators, may have an important role in reducing the increase of cytokine production in anthrax lethal toxin-treated macrophages.

Recently a B cell surface molecule, CD40, has emerged as a receptor mediating a co-stimulatory signal for B cell proliferation and differentiation. To investigate the mechanism of synergy between interleukin-4 (IL-4) and CD40 ligation in B cell activation, we have examined the effect of CE40 cross-linking on the IL-4 receptor expression in human B cells using anti-CE40 antibody. We observed that IL-4 and anti-CD40 both induce IL-4 receptor gene expression with a rapid kinetics resulting in a noticeable accumulation of IL-4 receptor mRNA within 4 h. While IL-4 caused a dose-dependent induction of surface IL-4 receptor expression, the inclusion of anti-CD40 in the IL-4-treated culture, further up-regulated the IL-4-induced IL-4 receptor expression as analyzed by flow cytometry. Pretreatment of B cells with inhibitors of protein tyrosine kinase (PTK) resulted in a significant inhibition of both the IL-4- and anti-CD40-induced IL-4 receptor mRNA levels, while protein kinase C (PKC) inhibitors had no effects. These results suggest that IL-4 and CD40 ligation generate B cell signals, which via PTK-dependent pathways, lead to the synergistic induction of IL-4 receptor gene expression. The rapid induction of IL-4 receptor gene expression through the tyrosine kinase-mediated signal transduction by B cell activating stimuli, would provide cells capacity for an efficient response to IL-4 in the early phase of IL-4 action, and may in part constitute the molecular basis of the reported anti-CD40 co-stimulatory effect on the IL-4-induced response.
