    サイジングは様々な紙板紙グレードへ液体耐性を付与する重要な特性のひとつである。過去数十年間に起きたイノベーションにもかかわらず,サイジング性能,抄紙効率,サイズ剤要求度低減,適用時の簡便さに対する要求は依然存在する。これらニーズに取り組むため,本報告はアルケニルコハク酸無水物(ASA)ベースの新しいサイズ剤の開発について概説する。標準サイズ度試験,パイロットスケール試験,リサイクル繊維板紙工場でのいくつかの抄紙機試験を通じて,新しいサイズ剤は少なくとも従来のASAサイズ剤と比べ優れたサイズ性能をもたらすことが確認され,同時に物流負荷も低減した。この新しい技術はサイズ剤使用量全体を少なくし,また関連するサイズ剤の貯蔵と荷扱いをシンプルにすることで,より効率的なサイジングを実現すると考えられる。より長期のフィールド評価,ロジンおよびAKDなどの他のサイジングプログラムに対する優位性評価が今後の課題である。

    In early 1977, U. S. President Jimmy Carter announced that U. S. ground combat forces would be carefully withdrawn from South Korea within a few years. His decision, however, was soon faced with strong resistance from the military and Congress. Officially because of a new intelligence estimate on North Korea's military capability, in June 1979, President Carter postponed immplementing his withdrawal plan till after the next presidential election in which he was severely defeated by Ronald Reagan.
    This failed attempt has been often regarded as a typical example of Carter's amateurish diplomacy. History tells us, however, that U. S. defense commitment towards South Korea has frequently fluctuated between the two extremes of intervention and withdrawal. This fluctuation seems to result from a dilemma in U. S. defense commitment towards South Korea: the United States has to provide enough credibility to maintain a favorable military balance in Northeast Asia without being too deeply involved in the defense of South Korea, which is not necessarily of vital interest for the United States.
    It is far from an easy task for Washington to escape from this dilemma. First of all, it is extremely hard to evaluate the strategic value of the Korean Peninsula in the context of U. S. global, regional and local strategies. Secondly, given the relatively decreasing U. S. economic capability and the diversified public opinion on foreign policy, a domestic consensus on a desirable degree of U. S. defense commitment towards South Korea cannot be easily obtained. Thirdly, regardless of changes in international and domestic situations, due to their vested interest in maintaining the U. S. presence in South Korea, the Army and the State Department bureaucracies tend to be opposed to reducing the defense commitment.
    After briefly reviewing the history of U. S. defense commitment towards South Korea, this paper intends to analyze how the Carter Administration tried to overcome the dilemma in U. S. defense commitment toward South Korea but was unsuccessful through the examination of the policy process of its withdrawal plan with available written materials and interviews with key participants.
