North Korea’s foreign policy track record in the post-cold war era is mixed. Most notable setbacks are the diplomatic normalization between the Soviet Union (now Russia) and South Korea; the reversal of its UN policy that paved the way for the simultaneous admission of the two Korean states to the world organization; and the diplomatic normalization between China and South Korea. On the credit side of Pyongyang’s diplomatic ledger are changes in its relations with Tokyo and Washington. While tangible results have yet to materialize, particularly in North Korea-Japan relations, the groundwork has nonetheless been laid for significant improvement. North Korea’s suspected nuclear weapons development program has played a major role in the unfolding of its relations with the United States. Conceptually, North Korean foreign policy can be explained in terms of its quest for three interrelated goals: security, legitimacy, and development. In the post-cold war era security appears to have emerged as the most important of the three goals. North Korea is at a crossroads. The choices it makes in foreign policy will determine not only the direction of its domestic policy but, ultimately, the survival of the regime itself. The external players in Seoul, Washington, Tokyo, Beijing, Moscow, and Vienna (the IAEA) have varying degrees of leverage over Pyongyang’s policy as well.  相似文献

A 22-year-old Korean soldier, who had received blows to the neck and epigastrium from an officer 10 h earlier, suddenly died after massive hematemesis. He had been in relatively good health except for episodes of blood-tinged vomiting approximately 5 and 7 months prior to this event. Postmortem examination revealed angiodysplasia involving the gastroesophageal junction, and the stomach was distended with blood. No abnormal findings were present around the whole viscera, and the duodenum was free of blood. The pathologic significance of upper gastrointestinal angiodysplasia as a potential source of bleeding and a chronologic correlation between the trauma and bleeding are discussed.  相似文献

Presented in this paper are the initial results involving the use of the nose or outer ear as temperature measurement sites to determine the postmortem period of the human corpse. Simple mathematical models for both sites are developed based on cooling curves of five corpses. Analysis of errors between actual and calculated postmortem intervals suggest that in its present form, the described methods would not be suitable for use in accurately determining the time since death of human corpses.  相似文献

Proposals to ration health care in the United States meet a number of objections, symbolic and literal. Nonetheless, an acceptance of the idea of rationing is a necessary first step toward universal health insurance. It must be understood that universal health care requires an acceptance of rationing, and that such an acceptance must precede enactment of a program, if it is to be economically sound and politically feasible. Commentators have argued that reform of the health care system should come before any effort to ration. On the contrary, rationing and reform cannot be separated. The former is the key to the latter, just as rationing is the key to universal health insurance.  相似文献

Why is that former dominant or single party regimes, especiallythose in Africa, have generally survived and even emerged strengthenedafter the introduction of multi-party competitive elections?In Côte d'lvoire since 1990 the ruling party has beenable to win elections by using incumbency to present itselfas the organization most likely to be capable of putting togethera winning coalition. In a society segmented by a multiplicityof cultural and religious divisions and where political poweris a zero-sum game, the logic of democratic representation meansthat no group can afford to be excluded. Yet in the 1990 and1995 Ivorian elections .the opposition attacked die ethnic characterof the government and deliberately mobilized ethnic minorities,regional and religious (Islamic) sentiments. They thereforefailed to escape, in electoral terms, from their extremely localizedstrongholds. Their attempt to mobilize around an anti-foreignerplatform in 1990 rebounded in 1995 when the government itselftook over their ‘ultra-nationalist’ stance by excludingnon-Ivorians from the elections. The consequent exclusion ofthe opposition's favoured Presidential candidate and the failureof the opposition alliance to agree on a non-northern, non-Islamicalternative candidate led to a violent boycott and the eventualcollapse of the opposition alliance.  相似文献

Incarceration rates in the United States dramatically increased over the past several decades. This trend has drawn significant academic attention to prison overcrowding and its potential effect on inmate misconduct. The empirical relationship between inmate misconduct and overcrowding, however, is less than clear. To be sure, studies indicating positive, negative, and null relationships can all be found in the literature. The current research subjects this body of literature to a meta-analysis in an effort to: (1) clarify the direction and strength of the relationship between overcrowding and rates of prison misconduct across all studies, and (2) to uncover the degree to which variation in research outcomes can be attributed to methodological differences across studies. Results indicate that prison crowding has little substantive impact on inmate misconduct. Implications of the findings are discussed in detail.  相似文献
