  • According to Chomskyan grammar, humans can generate and understand an unbounded number of grammatical sentences. Against the background of pure and idealized linguistic competence, this linguistic productivity is argued and understood. In actual utterances, however, there are many limitations of productivity but they are said to come from the general constraints on performances such as capacity of short term memory or attention. In this paper I discuss a problem raised against idealized productivity. I argue that linguistic productivity idealizes our linguistic competence too much. By separating idealized competence from the various constraints of performance, Chomskyan theorists can argue for unlimited productivity. However, the absolute distinction between grammar (pure competence) and parser (actual psychological processes) makes little sense when we explain the low acceptability(intelligibility) of center embedded sentences. Usually, the problem of center embedded sentence is explained in terms of memory shortage or other performance constraints. To explain the low acceptability, however, we need to assume specialized memory structure because the low acceptability occurs only with a specific type of syntactic pattern. 1 argue that this special memory structure should not be considered as a general performance constraint. It is a domain specific (specifically linguistic) constraints and an intrinsic part of human language processing. Recent development of Chomskyan grammar, i.e., minimalist approach seems to close the gap between pure competence and this type of specialized constraints. Chomsky's earlier approach of generative grammar focuses on end result of the generative derivation. However, economy principle (of minimalist approach) focuses on actual derivational processes. By having less mathematical or less idealized grammar, we can come closer to the actual computational processes that build syntactic structure of a sentence. In this way, we can have a more concrete picture of our linguistic competence, competence that is not detached from actual computational processes.

  • Objective : The purpose of this study was to investigate the effects of visual perception on driving performance and the importance of visual training for improving driving performance in patients with stroke. Methods : The evaluations, using MVPT(Motor-free Visual Perception Test), TMT A&B(Trail Making Test A & B), UFOV(Useful Field Of View test), and a driving simulator, were carried out with patients in department of physical medicine and rehabilitation in a rehabilitation hospital from October 2014 to November 2014. Results : Driving performance was related to the ability of various visual perceptions of patients with stroke, and the highest correlation was found in the UFOV subtest 2, TMT B, and MVPT. The results of discriminant analysis indicated a sensitivity of 100.0%, specificity of 80.0%, and predicted the results of the driving simulator with 89.5% accuracy. Conclusion : This study found that visual-perception skills influence driving performance and suggested the importance of visual-perception skill training for driving.

  • The change of job environments with information technologies demands workers' capabilities to adapt rapidly changing and variety of work environments. To cope with this situation, many countries and institutions propose 'basic vocational competency' which is focused on basic capabilities of workers. And also, they do research on how to educate and train students to be prepared for new environments. We surveyed with teachers of computer technology which is one of the information technologies, to find out the competency development level, they expressed negative view on general competency development because of current computer education's focusing on 'using computers to process information'. Therefore, we intended to analyze the necessity and problem of developing the whole basic vocational competency in vocational high school and proposed a 'in context' learning for it.

  • The growth of a game character is represented by the addition and subtraction of the status value. The status factors are variously defined and used depending on the kind of games. In this paper, we propose how character 's status elements are defined and used. We also propose a method for assigning a status value when generating a character considering growth. This method is designed using genetic algorithms to link the growth of a character with an element of time and to generate a character with the appropriate status value according to the change of time. The proposed method is verified through experiments based on time variation.

  • 인간공학을 적용하는데 있어 가장 기본적으로 다루어져야 할 것은 인간의 신체적, 심리적능력에 관한 연구이다. 특히 산업 현장에서 흔히 이루어지는 인간의 힘을 그 동력원으로 하는 수작업의 경우에 있어 서는 작업자가 직업적인 요인에 의해 피로가 누적되거나 신체적인 무리를 가져오지 않고 수행할 수 있는 안전한 작업기준의 설정이 필요하며 이를 위해서는 인간의 신체적 능격에관한 연구가 필수적이다. 특히 최근 들어 여성의 사회진출 기회가 다양해지고 있으며 많은 여성들이 육체적 노동을 필요로 하는 직업에 종사하고 있는 현실에서 한국여성들의 신체적 능력에 관한 자료가 절대적으로 부족한 상황이다. 따라서 본 연구에서는 현재 한국의 여성들이 활동하고 육체적 작업조건들이 적절하게 설정되어 있는지를 분석하기 위한 기초 자료로서 한국 여성들의 생리학적 작업능력(PWC:physiological work capacity)을 최대산소소모 능력(Maximal Oxygen Consumption: V0$_{2}$Max)의 관점에서 파악하고자 하였다. 또한 외국 여성의 생리 학적 작업능력과 한구 여성의 생리학적 작업능력을 비교 평가하여한국 여성에게 외국여성의 기준치를 적용 시키는 것이 적절한지를 분석해 보았다. 본 연구는 피실험자에게 위험부담을 주지 않는 Submaximal test의 연속적인 방법(continuous mathod)중 하나인 램프 테스트(Ramp test)를 사용하여 심박수(H.R)와 산소 소모 량(V0$_{2}$) 측정하여 최대심박수에서의 PWC를 추정하였다. 작업 부하는 자전거 에르고노미터와 트레드 밀을 사용하여부과하였다. 실험 결과로서 자전거 에르고미터의 경우 치대산소 소모량의 추정치 평균이 1818.79ml/min으로 나타 났고 트레드밀의 경우 2076.33ml/min으로 나타났다. 이 결과는 자전거 에르고 노미터의 결과는 자전거 에르고노미터의 결과가 트레드밀의 결과에 87.60%정도 나타났다.

  • In this ppaer, fault coverage analysis of a conformance test case for communication protocols, specified as a deterministic finite state machine(DFSM) is presented. The fault coverage analysis of a test case is defined by measuring the extent of the faults detected using a generated test case. The method that evaluates fault coverage analysis for a test case, has been researched by arithmetic analysis and simulation. In this paper, we designed and implemented a simulator for fault coverage analysis of a communication protocol teat case. With this result for Inres protocol, output fault and state merge and split fault have a high fault coverage of 100%. This simulator can be widely used with new fault coverage analysis tools by applying it to various protocols.

  • Purpose: Eye movements and fixation ability are an important procedure to obtain external information and essential means of clear vision. The purpose of this study was to determine the reading performance such as reading time and number of fixations when random text was viewed at varying distances. Methods: Twenty two presbyopes were participated. All subjects were screened for their suitability to participate in the study by clinical examination, and none of the participants had previously worn contact lenses and no previous experience of wearing any types of presbyopic vision correction except single vision. The reading time and number of fixations were recorded using eye tracker while each subjects was waring four vision corrections which included single vision for distance (SV), bifocal spectacle lenses (BIF), progressive addition lenses (PAL), and monovision (MV). The reading material was presented at distance and near distance. Results: Reading time and number of fixations for near stimulus were significantly different among vision correction used in this study (p<0.001). In particular, wearing SV required longer reading time and produced longer fixation duration for near text. However, reading distance text was similarity performed across vision corrections tested and there was no statistical difference found for either reading time and number of fixations. Conclusions: Wearing presbyopic vision correction is advantageous for reading task of near stimuli, but not having near correction such as wearing SV could result in longer reading time and higher number of fixation due to lacks of accommodative ability for near task. For the future studies, it would be interesting to examine the performance of reading both at adapted and unadapted stages as examining only unadapted wearers was limitation of this study.
