The fandom phenomenon of political emotion originated from ideological conflicts between the conservative and the progressive amplifies social conflicts in South Korea in interpreting and accepting films as culture media. The purpose of this paper is to examine why the structure of political consciousness in South Korea is fandomized, what is the acceptance of cinema at the center of the controversy of political ideology, and what is the desirable attitude of film reception. I conducted a discourse analysis that closely examined the debates and articles on the internet regarding ,(2013) and ,(2014) which were controversial in terms of conservatism and progressivism. As a result, First, while Korean society has not constituted a consensus on modern and contemporary history, it has easily led the acceptance of cinema to the controversy surrounding the political ideology. Second, the failure of constructing consensual memories of modern and contemporary history has made the conservative and the progressive not acknowledge the other's achievements. Third, film interpretation and meaning production are ultimately the roles of the audience, and on interpretation, diversity should be respected but conformity would be rejected. Film acceptance and interpretation should focus on rational awareness of social reality and would reflect on the social ideal objectively.

A Major aim of this study is to test the hypothesis that there is an association between empowerment, organizational memory, and new product creativity. In addition to exploring these relationships, this study examines the effect of new product creativity on new product performance, and identify the moderating effects of market uncertainty in the relationships between new product creativity and performance. For this purposes, we developed a research model based on the literature reviews of empowerment, organizational memory, market uncertainty, and new product creativity. A total of 121 usable survey responses has been used in the empirical research for foods manufacturing industry. The findings indicate that (1) Empowerment has a positive effect on new product creativity, (2) Organizational memory has a positive effect on new product creativity, (3) New product novelty has a positive effect on new product performance, and (4) Only competition uncertainty has a moderating effects between the new product meaningfulness and performance. The findings have implications for managers wishing to acquire the new product creativity and to better the new product development performance.

The present study is a conceptual replication of O'Grady, Lee, and Choo's (2003) earlier study designed to investigate two hypotheses (linear distance hypothesis vs. structural distance hypothesis) in relation to L2 Korean learners' processing of Korean subject and object relative clauses (RCs) in a scholarly attempt to explicate Keenan and Comrie's (1977) Noun Phrase Accessibility Hierarchy (NPAH). In addition, the current study is intended to explore any potential role of working memory capacity (WMC) in the processing of Korean subject and/or object RCs. Chinese-speaking learners of Korean taking a language course offered at a local university in Korea participated in this experimental study. Among those recruited, only 23 learners completed the experimental tasks appropriately according to the specific instructions provided on each task, and thus, subsequent statistical analyses were conducted on their data. Fifteen Korean NSs were also recruited for the control group. Two experimental tasks were administerd to the participants: one picture selection task containing the same test items used in O'Grady et al.'s study to measure their processing of subject-object RCs and an operation span (OSPAN) task to measure their WMC. Somewhat differently from O'Grady et al.'s findings, the participating Chinese learners of Korean performed significantly better on object RCs than on subject RCs, seemingly lending support to the linear distance hypothesis. Further analyses, however, suggested that the results in favor of, or relative ease of processing, object relative clauses were due, most likely, to the learners' excessive use of the canonical sentence strategy, which also led to nonsignificant correlations between WMC and learner performance on the picture selection task.

병렬 그래프 감축 모델에 있어서 투기적 연산(speculative evaluation)모델은 병렬성을 증가시키지만 불필요한 연산으로 인해 자원을 낭비할 수 있다. 투기적 태스크가 람다 연산식을 WHNF(Weak Head Normal Form)로 감축할 때, 대치과정은 그래프를 증가시킬 수 있고, 많은 복사과정을 요구할 수 있다. 이러한 투기적 태스크는 나중에 불필요한 연산이 될 수있고 이 경우 이러한 투기적 태스크에서 발생한 다른 모든 투기적 태스크들을 종료해야 하는 부담이 있다. 또한 불필요하게 된 복사과정으로 인한 기억 공간을 재사용이 가능한 상태로 만들어 주어야 한다. 본 논문은 WHNF 또는 HNF 로 감축할 대 발생할수 있는 불필요한 대치과정으로 인한 오버헤드를 줄이기 위해 대치과정이 지연된 람다 연산식 형태 (DSF : Deferred Substitution Form)를 제안한다. 이 형태는 대치과정을 필수적 태스크(mandatory task)가 수행될 때 까지 지연시키기 위한 람다 연산식 형태이다. 대치과정이 지연된 람다 연산식 형태로의 감축을 수행하는 투기적 태스크에서 , 대치과정이 존재하지 않기 때문에 그래프의 크기가 증가하지 않고 또한 복사과정을 요구하지 않는다. 따라서 연산식에 대한 대치과정이 지연된 람다 연산식 형태로의 감축이 불필요하게 된 경우 부담이 줄어들게 된다. 아울러 병렬성을 증가시키기 위한 연산모델을 제안한다.

The elderly population continues to increase in Korea and there has been a growing interest in understanding normal aging. In response to this public interest, the present paper reviewed human aging research focusing on recently published neuroimaging studies. For the first half of the paper, I reviewed the effects of aging on the brain and cognition. In normal aging, structural changes in the brain include atrophy and volume reduction in the prefrontal and temporal cortices. Functional changes are exhibited in the form of overactivation of the brain. Moreover, age-related cognitive decline is particularly observed in inhibition and memory, which are also associated with the age-related structural changes in the brain. For the second half of the paper, I introduced physical exercise studies showing that exercise played a protective role in the age-related neurocognitive decline. More specifically, engaging in physical exercise (particularly, aerobic exercise) for a relatively long period of time (e. g., > 6 mon.) protected older adults from volume loss in the prefrontal cortex and the hippocampus, and induced better inhibition and memory. These exercise-induced benefits appear to be associated with changes in neuronal levels, indicating that the aging brain is still plastic and this plasticity can be enhanced by physical exercise.

This study aimed to assess the spatial cognition strategies and roles taken by students in the process of solving spatial tasks. For the analysis, this study developed two spatial tests based on the mental rotation test, which were taken by 63 students in their final year in elementary schools. The results of this study showed that in terms of the method of approaching the tasks, students took the comprehensive approach and the partial approach. When solving the tasks, the students were shown to use the imagery thinking or analytic thinking method. In terms of perspective, the students rotated the object or change their perspectives. A comparison of the methods used by the students revealed that when approaching the tasks, the group of students who chose the partial approach had higher scores. In terms of solving the tasks the analytic thinking method, and in terms of perspective, changing perspectives were shown to be more effective. Such effective methods were used more frequently in discrimination tasks than in recognition tasks, and in more complicated items, than in less complicated items. In conclusion, the results of this study suggested that the partial, analytic approach and the change of perspectives are useful strategies in solving tasks which require high cognitive effort.

Optimal quantizers in conducting the entropy-constrained quantization for high bit rates have the lattice structure. The quantization process is simple due to the regular structure, and various quantization algorithms are proposed depending on the lattice. Such a lattice vector quantizer (VQ) can be implemented by using the sample-adaptive product quantizer (SAPQ) and its output can also be easily entropy encoded. In this paper, the entropy encoding scheme for the lattice VQ is proposed based on SAPQ, and the performance of the proposed lattice VQ, which is based on SAPQ with the entropy coder, is asymptotically compared as the rate increases. It is shown by experiment that the gain for the memoryless Gaussian source also approaches the theoretic gain for the uniform density case.

This paper has two aims (1) to address the common European past by way of considering the development of the official archives of the European Union; and (2) to give specific attention to the activities of archivists in Germany. The EU archives contain the all the documents officially recording the common history of European integration from the establishment of the European Coal and Steel Community in 1951. It was at the beginning of the 1980s, thirty years after the production of these documents, however, that the Archives of the European Community (EC) began to be systematized for public use when the European University Institute in Florence in Italy was chosen as the deposit location for the archive. After the coming into effect of the Maastricht Treaty in 1993, the EC Archives were renamed as the EU Archives. Through the cooperation of the national archives of the each Member State of the EU with this EC Archives common norms regarding deposit were developed. This archives is a veritable gold mine for serious research into all and any official aspect of the institutional and policy history of today's EU, so for the formation of common European identity. The denazification process using the evidence of the archives contributed to the orientation of the New Germany towards Europe. The German archives then have been contributing to the redressing the past to a significant degree since after the Second World War. More recently, the establishment of the "Memory, Responsibility, and Future" Foundation in 2000 in Germany made possible cooperations with the archives of the East European countries and especially for the purpose of the providing evidence about former enforced workers under the Nazi regime. There has thus been developed European-wide networks among archives. These developments have furthered the common redressing of the European past and this process in turn has been contributing the enhancing the European spirit and identity. The thesis of this paper then is that historical research based on the EU archives and individual Member States can not only illuminate in great detail the stages of the history of European integration to date. The dissemination of such research can itself contribute to the process of the spreading of supranational ideas beyond Europe to other regions of the world.

Cognitive reserve(CR) is the ability to optimize or maximize performance through complementary brain networks. CR is relevant to normal aging in cognitive-linguistic abilities. There are few domestic systematic reviews or meta-analyses that analyze the relationships between multiple CR and cognitive-linguistic domains in healthy older people. This meta-analysis included 32 studies published since 2000. In result, education level topped the list, followed by the occupation, cognitively stimulating activities, and the multilingualism. Most studies were related to memory, global cognition, and language. CR had a modest positive association with cognitive-linguistic performance. Multiple domains including memory and language also showed the significant correlations across most measures of CR. This study provides evidence-based information to support cognitive-linguistic ability in normal aging.

OpenMP 프로그램의 수행 중에 발생하는 자료 경합과 같은 병행성 오류는 디버깅을 위하여 반드시 탐지되어야만 한다. 그러나 이를 탐지하는 것은 어려운 일이다. 접근사건의 발생 후 관계를 기반으로하는 경합 탐지 기법은 프로그램의 수행 중에 발생하는 스레드의 병행성 정보를 식별하기위한 레이블을 생성하고, 생성된 스레드의 레이블을 기반으로 공유변수에 접근하는 사건을 접근역사를 통해 감시함으로써 경합을 탐지한다. 이러한 경합 탐지의 방법에서 레이블 생성을 위한 NR 레이블링 기법은 병행성 정보생성 시에 지역자료 구조를 사용함으로써 병목현상이 발생하지 않으며, 접근역사에 저장하는 레이블의 크기가 상수 값을 갖는 공간적 효율성을 제공한다. 또한 부모스레드의 정보역사를 정렬된 리스트 형태로 가져 병행성 정보 비교 시에 이진탐색이 가능하므로 시간적 효율성을 가지는 우수한 기법이다. 그러나, NR 레이블링은 레이블의 생성시에 부모스레드의 정보역사를 유지하기 위해서 내포 병렬성의 깊이에 의존하는 시간적 비용이 요구된다. 본 논문에서는 부모스레드의 정보역사 유지를 위해 상수적인 시간 및 공간적 복잡도를 갖도록 NR 레이블링 기법을 개선한다. 합성 프로그램을 이용하여 실험한 결과에서 개선된 기법은 최대 병렬성의 증가에 따라 레이블의 생성과 유지시 기존의 기법보다 평균 4.5배 빠르고, 레이블링을 위해 평균 3배 감소된 기억공간을 요구하며, 내포 병렬성에 의존적이지 않음을 보인다.
