This paper examines how Japanese society produced and reproduced a distinctively gendered history and memories of the experience of WWII and colonialism in the postwar era. We argue that these gendered narratives, which were embedded in postwar debates about the Peace Constitution and comfort women, have engendered contradictions and made the historical conflicts with neighboring countries challenging to resolve. On the one hand, this deepens conflict, but on the other, it also generates stability in East Asia. After Japan's defeat in WWII, the American Occupation government created the Peace Constitution, which permanently "renounces war as a sovereign right of the nation and the threat or use of force as means of settling international disputes." The removal of the state's monopoly on violence - the symbol of masculinity - resulted in Japan's feminization. This feminization led to collective forgetting of prewar imperialism and militarism in postwar Japan. While collectively forgetting the wartime history of comfort women within these feminized narratives, the conservative movement to revise the Peace Constitution attempted to recover Japan's masculinity for a new, autonomous role in international politics, as uncertainty in East Asia increased. Ironically, however, this effort strengthened Japan's femininity because it involved forgetting Japan's masculine role in the past. This forgetting has undermined efforts to achieve masculine independence, thus reinforcing dependence on the United States. Recurrent debates about the Peace Constitution and comfort women have influenced how Japanese political elites and intellectual society have constructed distinctive social institutions, imagined foreign relations, and framed contemporary problems, as indicated in their gendered restructuring of history.

A multithreaded model is a hybrid one which combines locality of execution of the von Neumann model with asynchronous data availability and implicit parallelism of the dataflow model. Much researches that have been made toward the advanced performance of multithreaded models are about the cache memory which have been proved to be efficient in the von Neumann model. To use an instruction cache or operand cache, the multithreaded models must have cache memories. If cache memories are added to the multithreaded model, they may have the disadvantage of high implementation cost in the mode. To solve these problems, we did not add cache memory but applied the method of executing the caching by using available registers of the multithreaded models. The available register-based caching method is one that use the registers which are not used on the execution of threads. It may accomplish the same effect as the cache memory. The multithreaded models can compute the number of available registers to be used during the process of the register optimization, and therefore this method can be easily applied on the models. By applying this method, we can also remove the access conflict and the bottleneck of frame memories. When we applied the proposed available register-based caching method, we found that there was an improved performance of the multithreaded model. Also, when the available-register-based caching method is compared with the cache based caching method, we found that there was the almost same execution overhead.

Main memory database systems use the different implementation techniques to sturucture and organize the user dta and system catalogs, since traditional database systems are optimized for the characteristics of disk storage environment. We present, in this paper, the design considerations for our main memory database system $ALTIBASE^{TM}$ that is currently applied to the time-critical applications. We focus on the design issues of storage manager in $ALTIBASE^{TM}$. The major components are introduced, and features and characteristics of transaction management and recovery method are described. We also present the database replication mechanism and its conflict resolution mechanism for high availability and performance. In order to evaluate our transaction performance, we show various experimental reports as measured by the TPS.

Records, especially the authentic records the nation secured, have an ontological feature of proof that is able to persuade the current present of the past present, and inherent in it is faith that originates from fundamental objectivity. Therefore the image of silence that such strictness of records creates realizes the detonation of specific memories through the act of visual exhibition. This research started from the notion that records achieve social vitality and return through its exhibition, as well as the critical awareness that it 're-mediate' the past and memory through interactions with image. The reason for viewing the archival exhibition as the subject of user analyzation is that in the process where exhibition sorts and arranges records, it is the tool and mediation that most distinctly exposes the identity of the archives. Hence, this research first analyzes national archives, particularly the exhibition of "presidential" records, which is in the center of memory conflict, in the viewpoint of the cultural practice of memory. Afterwards, it discusses empirical research and results on how users accept and resist the meaning of the exhibition through actual surveys of users after their viewing of an exhibition.

An XML is an markup language which has been focused on the next generation Web programming language. It easily represents the complex structure of a document, and it is possible to provide the access control over each component of an XML document. An implicit authorization technique means that granting an authorization to a node has effect on granting the same implicit authorization to its all descendants. Therefore, it enhances the time for the authorization grant and reduces the memory required for the authorization information. An authorization technique using an intention type and a authorization replacement solves a redundancy problem and decides whether the access is possible or the authorization conflict occurs at the first attempt.

트랜잭셔널 메모리는 다중 코어 시스템에서 lock 을 대체할 메모리 동기화 기법으로 소개되었다. 트랜잭셔널 메모리를 사용하는 시스템에서 같은 주소의 메모리에 동시에 접근하여 충돌이 일어난 트랜잭션은 충돌해결정책에 의해 유효화 될지 버려질지 선택된다. 기존의 트랜잭셔널 메모리는 고정된 충돌해결정책을 사용하여, 상황에 따라 가장 유리한 트랜잭션을 선택 해주지 못하는 한계가 있었다. 본 논문에서는 상황에 따라 여러 정책 중 유리한 충돌해결정책을 판단하여 적용시키는 방법을 제안한다. STAMP 벤치마크를 통한 시뮬레이션 결과, 제안하는 방법은 기존에 사용되는 Timestamp, Karma 충돌해결정책 대비 평균 22% 높은 성능 향상을 보였다.

To represent the relations of the data dependency and resource conflict among micro-operations(MOP's) in the compaction process of microprograms, we propose a DDM (data dependent matrix) representation method instead of the DAG (conventional directed acyclic graph). Also, we propose a global compaction algorithm of microprograms to prevent a kind of block copying by cutting the trace at a junction block. The DDM method and compaction algoristhm have been applied to the Lah's example. The results shows that the proposed algorithm is more efficient than the conventional algorithms in reducing in reducing the total execution time and control memory space.

The purpose of this study is to analyze and compare brain activation that appears in the self-regulation process of biology major and non-major college students in life science learning. The self-regulation task implemented a life science learning situation with the concept of biological classification. The brain activation of college students was measured and analyzed by fNIRS. In the assimilation process, bilateral FP and left DLPFC show significant activation, and the two groups show a difference in the left OFC activation related to motivation and reward. In the conflict process, the left DLPFC shows significantly lower activation in common, and the two groups show a difference in activation between BA 46, which is related to recent memory, and BA 47, which is related to long-term memory. In the accommodation process, a significantly high activation was found in right DLPFC in common, and the two groups show a difference in activation between right DLPFC and right FP. These areas are in the right frontal lobe area and are related to the understanding of life science knowledge. As a result of this study, it can be seen that the brain activation patterns of biology major and non-major college students are different in the self-regulation process. In addition, we will propose additional neurological studies on self-regulation and present systems and learning strategies that can be constructed in school settings.
