디스크의 구역분할기술(zoning technology)은 디스크의 저장용량과 평균 전송 대역폭을 증가시킴으로써, 디스크 서브시스템의 성능을 향상시켰다. 멀티미디어 시스템에서 구역분할 디스크의 성능을 충분히 이용하기 위하여 이중 버퍼링을 하는 SCAN 스케줄링을 사용한다. 하지만, 이 방식은 새로운 스트림의 요청 시에 지터(jitter)를 발생시키는 문제점이 있다. 본 논문에서는 이 문제를 해결하기 위한 선행버퍼링(pre-buffering) 기법을 제안한다. 선행 버퍼링은 디스크 서브시스템의 수학적 모델을 통하여 스트림의 개수에 따른 주기시간과 각 주기시간에 필요한 데이타 양, 그리고 새로운 스트림 요청 시에 발생하는 데이타의 부족분을 예측하고, 예상되는 데이타의 부족분을 각 스트림의 서비스 전에 미리 버퍼링함으로써, 지터를 방지한다. 선행 버퍼링 기법은 멀티미디어 서버에 적용되어 사용자에게 지터 없는 고품질의 서비스를 제공하는 데 기여할 수 있다. Zoning technology of disk improved the performance of disk subsystem with increase of storage capacity and average transfer bandwidth. SCAN disk scheduling with double buffering is used to utilize the performance of zoned disk in multimedia system. However, this method has a problem that generates jitter when the number of steams increases. In this article, we propose the novel approach, pre-buffering policy, to overcome this problem. Pre-buffering avoids jitter by buffering the lack of data before starting service, which is estimated from the current cycle length and the maximum cycle length. We can calculate cycle length, data size needed in each cycle and the possible lack of data caused by the increase of the number of streams using the numerical model of disk subsystem. Pre-buffering can be applied for multimedia systems and contribute to provide clients with high quality service without jitter.

  The aim of this paper is to establish the Korean basic sentence type that is connected with mother tongue of foreign student who study the Korean language. In other words, if the basic sentence type is established on the common sentence type of languages, a student will learn easily Korean sentence type.<BR>  After this paper establishes the Korean basic sentence type, this paper compares the argument structure of the Korean language with the India-Europe language. The common basic sentence type structures of the Korean language and India-Europe language are as follows. The first, the basic sentence type structure 1 that has no argument. The second, the basic sentence type structure 2 that has one argument. The third, the basic sentence type structure 3 that has two arguments. The last, the basic sentence type structure 4 that has three arguments.<BR>  The Korean basic sentence type of this paper shows the Korean basic sentence type frame. Specially, the no argument sentence like “An-nyeongha-se-yo?” is base on the basic sentence type structure 1. And, the Korean basic sentence type structure of this paper includes all Korean sentences is composed of the primitive elements. As this paper makes the Korean basic sentence type structure by comparison with other language(the India-Europe), foreign students study the Korean language easily.

This thesis is about the change of possession of 'root-Juda' dative verbs in Korean. The dative verbs describes the change of possession from a possessor to a beneficiary in a dative constructions. The primary situation in a dative construction is the movement of possession. Any change of possession can be classified three types according to degree of possession; (1) a transfer of possession, (2) a trust of possession, (3) a share of possession. It is founded the change of possession in 'Root-Juda' dative verbs. The root to appear the change of possession is the core of 'root-Juda' dative verbs. This thesis is to analysis the succeeding the change of possession from witch root to a 'root-Juda' dative compound verb. The results of this thesis are summarized in these words. While 'Juda' compound a root of giveness, The root of giveness is responsible the change of possession and the method and manner of action and 'Juda' is responsible a spesker's beneficient. While 'Jusa' compound a root of non-giveness, 'Juda' is responsible the change of possession and the root of giveness is responsible the method and manner of action.

Waiting in line at a fashion store: psychological and emotional responses

박수진,Kyeongsun Min,이유리 한국의류학회 2014 Fashion and Textiles Vol.1 No.1

Waiting in a service context is known to negatively affect consumer evaluation of services and service providers. However, this study investigates the positive effects of waiting—such as expected customer competition, excitement, and purchase intention—during the purchase of fashion merchandise. We classified waiting into four types based on whether waiting occurs, whether customers receiver a filler, or whether a filler is related to the context. A scenario-based online survey was conducted for empirical testing. After reading the scenario, 266 respondents replied to a questionnaire regarding expected competition, excitement, and purchase intention. The findings indicated that expected competition, excitement, and purchase intention differed significantly according to the wait type. Customers provided with a context-related filler reported the highest expected competition, excitement, and purchase intention, and excitement was found to mediate the relationship between expected competition and purchase intention. This paper ends by discussing its implications for managing waiting at a fashion store.

Jinho Han,Youngsu Kwon,Kyeongsun Shin,Hoi-Jun Yoo 대한전자공학회 2017 Journal of semiconductor technology and science Vol.17 No.5

The processor is becoming increasingly susceptible to transient faults with fluctuating voltage, widening operating temperature, and increasing clock frequency. Especially, processor, operating near threshold voltage for a low power, can expose to transient faults with the thin margin of process, voltage, and temperature. This paper presents a fault tolerant processor having on-chip fault monitor systems for processor core and cache, which detects faults and corrects faults, and a fault injector which injects faults for testing. The fault tolerant feature is analyzed by a fault injection and quantitative analysis complying with ISO26262 standard. As a result, the proposed work achieves 80 μW/MHz energy efficiency, 850 MHz maximum frequency, 72% fault trap reduction, and 99.23% single point fault failure rate complying with ISO26262.

2015 개정 교육과정에서의 핵심역량 관련 이슈 고찰: 인간상, 교육 목표, 교과 역량과의 관계

이광우 ( Kwangwoo Lee ),백경선 ( Kyeongsun Beak ),이수정 ( Soo Jung Lee ) 한국교육과정학회 2017 교육과정연구 Vol.35 No.2

2015 개정 교육과정이 2015년 9월 23일 개정 고시되었으며, 이 교육과정에서는 `지식정보 사회가 요구하는 핵심역량을 갖춘 창의융합형 인재상`을 제시하였다. 2015 개정 교육과정의 주요 방향은 교육과정 설계에서 어떻게 핵심역량을 구현할 것인가에 있었으며, 이를 구현하기 위해 교과 역량, 핵심개념, 기능 등 새로운 개념이 도입되었다. 그러나 교육과정 개정 이후 도입된 새로운 개념에 대한 반성적 논의들이 제기되고 있다. 따라서 이글의 목적은 핵심역량과 관련하여 제기되는 몇 가지 이슈를 검토하고 향후 과제를 논의하고자 한다. 첫째, 인간상, 핵심역량, 교육 목표와의 관계를 검토하였다. 이들 관계를 검토하기 위해 핵심역량의 성격을 규정하였는 바, 2015 개정 교육과정에서 핵심역량은 교육의 방향과 교육 목표적 성격을 지니는 것으로 파악되었다. 핵심역량이 어떠한 성격을 견지하느냐에 따라 인간상, 핵심역량, 교육 목표간 진술의 연계와 수준이 다르게 진행될 수 있음을 검토 과제로 제안하였다. 둘째, 핵심역량과 교과 역량과의 관계를 검토하였다. 2015 개정 교육과정에서 이 둘간의 관계는 총론의 핵심역량이 범교과적 일반 역량으로서 교과 역량 설정의 근거로 작용하는 것으로 규정하였다. 또한 교과 역량 설정에 있어서 총론의 핵심역량, 교과의 성격과 논리 등이 고려되어야 한다고 보았다. 그러나 설정된 교과별 역량은 주로 총론의 핵심역량을 모방하는 수준에서 설정된 것으로 나타났다. 이에 향후 검토 과제로 교과 역량 설정의 세 가지 측면을 제안하였다. The 2015 Revised Curriculum announced on September 23, 2015, presented the educated person as `a creative and integrative learner possessing key competencies necessary for the knowledge and information society.` The major direction of the revision was how to embody key competencies in curriculum design, and new concepts, such as subject competencies, key concepts, and functions, were introduced for this embodiment. However, reflective arguments regarding these new concepts have been proposed since the curriculum revision. This paper examines the issues related to key competencies and discusses future tasks. First, the paper investigates the relationship between the idea of the educated person, key competencies, and educational goals. An examination of the key competencies of the 2015 Revised Curriculum reveals that they have two properties: educational direction and an educational goal. Second, this paper studies the relationship between key competencies and subject competencies. It is found that the key competencies of the national guidelines function as general competencies across curricular subjects and serve as the basis for establishing subject competencies. Finally, the paper proposes three approaches to establishing subject competencies in future tasks.

백인호,이규환,어경선 大韓神經精神醫學會 1994 신경정신의학 Vol.33 No.4

Objects: This study was dwsigned for the wvaluation of the association between the TRH stimulation test response and somatic symptoms in the patients with major depression. Methods: The subjects were consisted of 26 depressed patients. They received a TRH stimulation test. Their alexithymic trend were assessed with SSPS and their subjective wymptoms were assessed with SAS and SDS at least 1 week before the test. The frequency of their somatic symptoms were evaluated through interview using the symptom list in the somatization disorder in DSM-Ⅲ-R. The subjects were divided into the blunted response group and the non-blunted response group according to the response of TRH stimulation test and the frequency of their somatic symptoms, alexithymic trend and subjective symptoms were compared between the two groups. Results: 1)There were no significant difference of sex, age and the score of current GAF(global assessment of functioning) between the blunted response group and the non-blunted response group. 2)The score of SSPS was significantly higher in the blunted response group than that in the non-blunted response group statistically(P=0.035). There were no significant difference in two self-report scales. 3)Abdominal discomforts(P=0.039) and back pain(P=0.019) were significantly higher in the blunted response group than those in the non-blunted response group. Conclusion: These results suggested that alexithymic trend, especially the score of SSPS. and some somatic symptoms such as abdominal discomforts and back pain may influence the results of TRH stimulation test in depressed patients.
