The purpose of this study was to explore the adaptability of U.S. multiple-choice items to measure Mathematical Knowledge for Teaching (MKT) in Korea. For this purpose, the authors selected the number and operations form B which was developed by Learning Mathematics for Teaching (LMT) project at the University of Michigan and then adapted items in terms of general cultural context, school cultural context, mathematical substances, and language in Korea. The survey was administrated to 77 Korean in-service teachers who had more than three years of teaching experiences. Based on the survey, the authors compared the data to that of U.S. teachers who had participated California's Mathematics Professional Development Institute. As a result, the survey measures less knowledge Korean teachers than more knowledgable Korean teachers and there are strong correlations of relative item difficulties between Korean teachers and U.S. teachers for both Content Knowledge (CK) items and Knowledge of Content and Students (KCS) items. This study implies the future direction for developing items to measure teacher knowledge as well as designing effective teacher education programs.

We are evidently Home Economicus, egoistic rational utility maximiger, and all the capitalism economic situation make us adapt to such life, and recognize that it is rational to act like that. This can be demonstrated in Prisoner′s Dilemma(PD) which always select the non-cooperative choice for free rider in rational selection process of public goods. This paper notice the "what is problem\ulcorner"The problem is not in free rider itself but in free rider egoism. The practical behavior of free rider egoism can be explained by way of Prisoner′s Dilemma. In PD situation, the prisoner makes a rational choice, non-cooperative alternative, but he doesn′arrive at preto-optimality. It is dilemma. Why can′t he arrive \ulcorner Because he is isolated from other prisoner. So we call it prisoner′s dilemma. The PD situation can be compared with our real economic life, which, we think, have kept by rational choice of the public goods. We actually have made our life as an individual one although we organized communities of capitalism. Of course, we know each others as members of same society, but each individual being can′t secure the belief, which has composed basis of community. So, it is very similar and common between PD situation and our real economic life in the production of public goods. We conclude that this non-cooperative process of PD situation can be utilized as instrument of EE. So this non-cooperative process can show us the effectiveness of EE as follows. \circled1 Game situation life PD can be used as good instrument for explaining the rational selection dilemma(error) to Homo-Economicus, the rational agent, with the optimal and rational language. \circled2 We can show that the selection result is dilemma, not arrive pareto - optimality. \circled3 The dilemma can be resolved with accomplishing the good communal life based on the belief, not on the isolation.

The purpose of this paper is to investigate search efficiency of controlled vocabulary versus uncontrolled vocabulary subject access in online catalog systems. The question of the effectiveness of controlled versus uncontrolled vocabulary in information retrieval has been raised in many literatures. A debate continues in the Library and Information Science Professions over the relative merit, appropriateness, and efficiency of uncontrolled vocabulary subject access in online catalog systems. Actually users used to combine uncontrolled vocabulary subject searching with controlled vocabulary subject searching. But the success of user's subject search depends on his choice of search terms. Also the technical developments that facilitate cooperation among information services in general make it increasingly possible for such cooperation to take place on an international level. In this study, several common types of vocabularies on online catalog systems are described and compared, especially usages of vocabularies in multilingual environment are analyzed.

자연어 분석에서 발생하는 가장 큰 문제점은 분석의 각 단계에서 필요 이상의 모호성이 발생하는 것이다. 이러한 모호성은 각각의 분석 단계에서는 반드시 필요한 결과일 수 있지만 다음 단계의 관점에서는 불필요하게 과생성된 자료로 볼 수 있다. 특히 한국어 형태소 분석 단계는 주어진 문장에 대해 최소의 의미를 가지는 형태소로 분석하기 때문에 과생성된 결과를 많이 만들어 내는데, 이들 대부분이 보조용언이나 의존 명사를 포함하는 형태소열에서 발생한다. 품사 태깅된 코퍼스에서 높은 빈도를 나타내는 형태소들을 분석해 보면 주위의 형태소와 강한 결합 관계를 가지는 것을 발견할 수 있다. 이러한 형태소는 대부분 자립성이 없는 기능형태소로서, 개개의 형태소가 가지는 의미의 합으로 표현되기보다는 문장내에서 하나의 구문 단위로 표현될 수 있다. 본 논문에서는 이 형태소 열을 구문 형태소로 정의하고, 필요한 경우 일반 형태소 해석의 결과를 구문 형태소 단위로 결합하고 이를 바탕으로 구문 해석을 하는 방법을 제안한다. 구문 형태소 단위를 이용하여 구문해석을 수행함으로써, 형태소 해석 결과의 축소를 통해 불필요한 구문 해석 곁과를 배제할 수 있다.

This paper examines the relationship and ideas of Hannah Arendt and Philip Roth including how they met, their correspondence and intellectual parallels, particularly in their shared criticism of Jewish ideals and culture in Europe and North America. It analyzes similarities in their careers and texts, especially between Eichmann in Jerusalem and Operation Shylock, as well as The Ghost Writer, while measuring their reception as social commentators and writers. Kafka was an important figure for both writers, Arendt's earliest writing engaged with the significance of Kafka in understanding and criticizing twentieth century political and cultural values in Europe. For Roth, Kafka offered a similar critique of moral principles he found corroded in North American Jewish life. Arendt connected with other writers, notably Isak Dinesen, W. H. Auden, Randall Jarrell and William Styron who further linked the two: he knew both Arendt and Roth and cited, incorrectly, a work by Arendt as the source for the key incident in his 1979 novel Sophie's Choice. He claimed it was Eichmann in Jerusalem; it was Arendt's The Origins of Totalitarianism. Arendt's reaction to Roth's fiction, however, remains a mystery: she died in 1975, before Roth began to seriously and consistently engage with Holocaust issues in works like The Ghost Writer (1979) and Operation Shylock (1993). Yet even in death they are joined. Their graves are only steps apart at the Bard College Cemetery in Annandale-on-Hudson, New York.

Objectives : The purpose of this study is to help select an appropriate word embedding method when analyzing East Asian traditional medicine texts as data. Methods : Based on prescription data that imply traditional methods in traditional East Asian medicine, we have examined 4 count-based word embedding and 2 prediction-based word embedding methods. In order to intuitively compare these word embedding methods, we proposed a "prescription generating game" and compared its results with those from the application of the 6 methods. Results : When the adjacent vectors are extracted, the count-based word embedding method derives the main herbs that are frequently used in conjunction with each other. On the other hand, in the prediction-based word embedding method, the synonyms of the herbs were derived. Conclusions : Counting based word embedding methods seems to be more effective than prediction-based word embedding methods in analyzing the use of domesticated herbs. Among count-based word embedding methods, the TF-vector method tends to exaggerate the frequency effect, and hence the TF-IDF vector or co-word vector may be a more reasonable choice. Also, the t-score vector may be recommended in search for unusual information that could not be found in frequency. On the other hand, prediction-based embedding seems to be effective when deriving the bases of similar meanings in context.

The purpose of this article is to examine how Byron's Don Juan VII-VIII depicts the various facets of characters' minds and actions in taking attitude toward glory during wartime in Ismail, Turkey. It explores the multifaceted sides of their hidden intentions and military activities in the self-centered and ruthless battle. Byron investigates their diverse and unreasonable causes, which drive them to undertake their particular deeds while participating in the combat. He unfolds the complex, dark layers of man's motivations and acts in responding to such martial ideals as fame, honor, success, or triumph. By making an effective characterization of four major figures such as Suwarrow, Juan, Johnson, and the Turkish Khan, Byron, indeed, enriches the poem with a variety of their different conceptions and stances toward these remarkable achievements. While fighting in the same battle, they, interestingly, reveal strikingly different attitudes, especially in responding to the complex aspects of reputation, glory, war, manliness or fate. The article also considers how the two Cantos of Don Juan feature the ironic results of the characters' quest for glory, which bring about an extensive range of inhuman consequences. The poet accentuates the diverse, negative aftermaths of their illusionary, abusive pursuit of fame and honor. In doing so, he effectively utilizes figurative portrayals of brutal pictures to highlight the unanticipated boundaries and dreadful outcomes, which have been caused by the undesirable or irrational exercises of their freedom of choice in pursuing such self-centered desires and renown.

Purpose : We investigated the career choice and the employment preparation of emergency medical technology (EMT) students. The results of study will provide the base information about the consciousness for career choice and employment of the EMT students. Method : We conducted 1,586 surveys from 665 students at six four-year colleges and 921 students at seven three-year colleges, from Aug. 27th to Oct. 31st in 2010. The result was analyzed by SPSS 18.0 using description statistics, t-test, ANOVA, Scheffe and Pearson correlation coefficient. Result : The general characteristics showed male 50.2% and female 49.8%, and first grade 34.6%, second grade 27.4%, third grade 28.2%, and fourth grade 9.8%. The 53.9% of students had experienced the hospital training and the 44.8% did the fire station training. For the choice of job, there were the 61.8% student who hope to enter the employ in fire station or public service, while 25.7% students hope to be employed in hospitals. The reason for a wish job were 'majors-related job' in 18.2% students, 'employment stability' in 17.2% and 'hit on the aptitude and talent' in 16.7%, 'appropriate salaries' in 15.9%. In the questionnaire of the University what to assist you for job preparation, they chose the 'support for get major related license', 'support for officer exam preparation' and 'support of foreign language study' in 34.6%, 16.8% and 16.6%, respectively. For achieved licence, they had a driver's license in 53.9%, BLS (basic life support) provider in 20.3%, life guard in 16.2% and scuba in 8.8%. The statistically significant correlation was identified between the awareness of University that provides job information and one's career awareness (r= .203, p<.000), the awareness that University provide job information and one's confidence in employment (r= .236, p<.000), and one's career awareness and one's confidence in employment (r = .356, p = .000). Conclusion : The most of EMT Students are well conscious of the their future employment and has prepared career to be employed their preference job.

Telematics and LBS is one of rapidly emerged technology domains. In order to efficiently construct them, moving object technology which manages huge volume of real-time location data is required. Especially, the query which obtains special sorts of information closely related to the detailed applications is required in order to effectively retrieve and analyze the location data for moving object in logistics domain. It has also complex query structure comparing to the conventional database query. The approach using the standard database query language, like SQL, can be considered as an effective alternative choice. In this paper, we not only propose a new query language, entitled as MOQL based on SQL, for the query processing of the vehicle monitoring and control in e-Logistics but also design and implement the query processor.

This study aimed to examine how Korean-English bilinguals make use of VOT and F0 cues in perception and production of Korean (lenis vs. aspirated) and English (voiced vs. voiceless) stops. It was explored whether bilinguals with extensive experience living in the U.S. exhibit native-like or interactive patterns in the cue use for both languages. Participants produced monosyllabic word-initial stops within a carrier sentence in each language, and performed forced-choice identification tasks with synthesized stimuli varying in 7 VOT steps and 7 F0 steps with base tokens of /$t^han$/ for Korean and /$t{\ae}n$/ for English. Listeners were required to select either /tan/ or /$t^han$/ for Korean and either /$d{\ae}n$/ or /$t{\ae}n$/ for English. The results from binary logistic regression analyses for each listener indicated that all bilinguals placed greater weight on F0 than VOT when distinguishing between the Korean lenis and aspirated stops, and greater weight on VOT than F0 in distinguishing between the English voiced and voiceless stops. In terms of production, all participants showed remarkably overlapping ranges in the VOT dimension and separating ranges in the F0 dimension for the stop contrast of Korean, while forming overlapping ranges in the F0 dimension and separating ranges in the VOT dimension for the stop contrast of English. These results indicate that the bilinguals with extensive exposure to L2 manage the stop systems of the two languages independently, both in perception and production, employing the opposite cue use for stops in the two languages. It was also found that the absolute beta-coefficient values of the perceptual cues for Korean stops were generally smaller than those for English and those reported in a previous study as for later bilinguals, which may have resulted from Korean not being their dominant language.
