다각형 P의 내부를 지나지 않는 선분 L로 부터 P의 경계가 모두 보이면 L을 P의 외부가시선분이라 한다. Shin은 정점이 n개인 다각형 P가 주어졌을 때 P의 외부가시선분이 존재하는 가를 조사하고 존재할 경우 외부가시선분을 구하는 O(nlogn) 시간 알고리즘을 제시하였고 Bhattacharya 등은 다각형의 sector 가시성을 이용하여 같은 문제가 O(n) 시간에 해결됨을 보였다. Bhattacharya와 Toussaint은 주어진 다각형이 정점이 n개인 볼록다각형일 때 최단 외부가시선분을 구하는 O(n) 시간 알고리즘을 제시하였다. 본 논문에서는 정점이 n개인 단순다각형 P가 주어졌을 때 P의 최단 외부가시선분을 구하는 O(n) 시간 알고리즘을 제시한다.

음운 교육 내용으로 <표준 발음법>이 타당한가

Even though Korean native speakers don’t know the ‘Korean standard pronunciation rules’, they can pronounce the standard pronunciation. In other words, actual Korean native speaker"s pronunciation is different from ‘Korean standard pronunciation rules". Teaching ‘Korean standard pronunciation rules’ means teaching the articles of ‘Korean standard pronunciation rules". I agree that phonology education should include standard pronunciation, but I oppose to include ‘Korean standard pronunciation rules’ in the curriculum of Korean language education. In the current curriculum, the contents of phonology unit in the grammar section, in particular, is similar to the contents of ‘Korean standard pronunciation rules’. However, "Korean standard rules" are fundamentally different from the grammar rules in that the contents of phonology unit in grammar aims to research purposes whereas the pronunciations rules are not. Moreover, the "standard rules" are for judging what is right or wrong in pronouncing Korean, which is not a desirable goal of phonology education. In this thesis, therefore, I insist that the contents of ‘Korean standard pronunciation rules’ should be removed from the phonology unit of the grammar section.

글로우 방전을 이용한 이산화탄소의 전환특성

신용섭,송승훈,곽동주 慶星大學校 1998 論文集 Vol.19 No.2

In this study, the characteristics of CO₂conversion and glow discharge were investigated using glow discharge plasma reactor with a parallel copper electrode system. A pure CO₂ gas was used for the carrier gas under gas pressure of 10∼80 torr in a glow discharge. For glow discharge, discharge current was increased with the increase of discharge voltage. In the case of constant discharge voltage, the discharge current tend to increase with the decreasing of gas pressure. Using pure CO₂only, the CO₂conversion was increased with the increase of discharge power and the decreased of gas pressure. The maximum CO₂ conversion was 28% at 10 torr, 598 W, 902.4V. Energy yield was decreased with the increase of discharge power and discharge voltage. Also, the concentrations of CO₂and O₂in the produced gas were slightly increased with the increase of CO₂ conversion.

창의성 및 정보과학적 특성을 기반으로 한 정보영재 판별도구 개발연구

오늘날 정보화가 빠르게 진행되면서 정보과학의 중요성이 수학, 과학의 중요성 못지않게 대두되고 있기 때문에 이 분야의 영재 역시 조기에 판별하여 교육시켜야 한다는 필요성이 강조되고 있다. 하지만 이에 대한 연구는 초보적인 단계에 머물고 있다. 이에, 본 연구에서는 영재의 판별에 대한 이론적 고찰을 통해서 영재의 특성, 정의 및 판별방법과 도구의 제작과정을 살펴보고 영재의 올바른 판별과정을 조사, 분석하였다. 또한 이를 바탕으로 정보과학의 기반이 되는 이산수학의 특성을 규정하여 이를 바탕으로 정보영재의 특성 및 정의를 내렸으며 이를 근거로 정보영재를 판별할 수 있는 도구를 제작하였다. 판별도구를 이용하여 적용한 결과 판별도구는 신뢰성이 있는 것으로 분석되었으며 향후 정보영재의 의미 있는 판별도구로 활용될 수 있을 수 것이다. Since the science of information is appearing no less important than mathematics and natural science as our society is rapidly becoming information-oriented, the necessity to distinguish prodigies of this field and to educate them as early as possible is also being emphasized. Unfortunately, however, the pertinent study is still in its beginning stage. In this study, I have reviewed the character, definition and method to distinguish prodigies and the procedure of developing a test, as well as researching and analyzing the proper process of distinguishing prodigies, through theoretical contemplation on the method of distinguishing the gifted children. Also, I have characterized and defined the information prodigies after clarifying the character of 'Discrete Mathematics' which becomes the basis of the science of information, paving the way to make a test method that can distinguish those information prodigies. As a result of our applying the system by using the distinction test, it turned out that the distinction test was pretty reliable. Accordingly, it can be utilized as a significant distinction test for information prodigies in the forthcoming future.

To improve fatigue properties, usually the shot peening process is used in the industrial world. In order to achieve optimum, repeatable and reliable shot peening process, the important shot peening parameters must be controlled. The first item needed to achieve high quality shot peening is to keep shot balls in a good quality. This paper discusses of shape of commonly used shot ball. Also, discussed is shot ball Shape's effect of Fatigue Life.

AWRR 셀 스케쥴링 알고리즘

신승수,신동화,지홍일,최승권,조용환 충북대학교 산업과학기술연구소 2002 산업과학기술연구 논문집 Vol.16 No.1

The Binary Scheduling Wheel(BSW) algorithm was proposed to carry on manage buffer efficiently at implementing of WRR scheduler. But, BSW algorithm cause serous performance degradation of cell delay and maximum queue length because it allocates more weight than the weight allocated actually in VC and could not serve cell if the VC queue is empty. In this paper, we propose new BSW of the old BSW structure. Also, we develop a cell scheduling algorithm which is suitable for the new BSW structure. The proposed BSW structure and the developed algorithm are capable of maintaining the allocated weight of each VC correctly, and decrease average cell delay and average buffer length by serving other VC cell when the selected VC queue is empty, and increase cell service ratio as a whole. The evaluation results show that the proposed structure can implement WRR algorithm more efficiently than the old BSW.

In order to evaluate the efficacy and safety of risperidone, 10 patients with chronic schizophrenia were examined for 8 weeks in a silgle-open study. After the wash-out period of 1 week, risperidone was administered. Efficacy was evaluated by means of Positive and Negative syndrome Scale for Schizophernia(PANSS) and Clinical Global Impression(CGI). Safety assessment included the Extrapyramidal Symptom Rating Scale(ESRS), vital signs, body weight, ECG, and laboratory tests. The results were as follows 1) On the PANSS total score, there was significant improvement of total score after 1 week (P<.05) of administratiom. 2) On the PANSS positive and negative subscal, there were significant improvement of posotive and negative scores after 2 weeks (P<.05) of administration. 3) On the PANSS general psychopatholgy subscals, there were significant improvement of general psychopathologyscores after 1 week (P<.05) of administratiom. 4) On the CGI, there was significant decreasement of clinical impression of severity of schizophrenia score after 2 week (P<.05) of administration. 5) A statistically significant increase in body weight (P<.05) was observed after 8 weeks of administration. 6) EPS reached the peak at the end of the 1st week of administration of risperidone (11.8± 24.25) but they were easily relieved by addition of benztropine and clonazepam. There was not significant change in laboratory tests, vital sign, ECG after 8 weeks of administration. These results suggest that Risperidone is an effective antipsychotics and clinically safe except for increased body weight in chronic schizophrenia.

/k/>/h/ 變化에 對한 考察

신승용 국어학회 2003 국어학 Vol.41 No.-

본고는 중세국어와 경상벙언의 /h/:/k/ 대응에 내재된 변화의 방향을 究明하고자 한 것이다. /h/:/k/ 대응에 내재된 변화는 중세국어 이후의 /h/>/k/가 아니라, 중세국어보다 앞선 시기에 일어난 /k/>/h/였다. 이는 기왕에 중세국어와 경상방언의 ‘ㅇ’:/k/ 대응에서 경상방언의 /k/를 중세국어보다 앞선 단계의 것으로 파악한 것과 평행하게 /h/:/k/ 대응에서도 경상방언의 /k/를 중세국어보다 앞선 단계의 것으로 이해한 것이다. 또한 중세국어의 ‘ㅇ[??]’을 설명하는 자리에서 상정해 온 ^(*)g>^(*)r>??가 음운론적으로는 결국 /^(*)k/>/h/>Ø(또는 /^(*)k/>/h/>[??]>Ø)임을 논증하였다. 그럼으로써 기왕에 별개의 사건으로 보아 왔던 중세국어와 경상방언의 /h/:/k/ 대응과 ‘ㅇ’:/k/ 대응을 하나의 통시적 사건으로 해석할 수 있게 되었다. This thesis aims for examining a direction of changing that is involved in the correspondence of Middle Korean /h/ and Kyeongsang Dialect /k/. Up to now, it is generally accepted that Kyeongsang Dialect /k/ is changed from Middle Korean /k/. But I have proved that the a direction of changing in the correspondence of Middle Korean /h/ and Kyeongsang Dialect /k/ is not /h/>/k/ after Middle Korean, but /k/>/h/ before Middle Korean. That is to say, Kyeongsang Dialect /k/ is older than Middle Korean /h/ in the correspondence of /h/:/k/. It is parallel of the exiting explanation that Kyeongsang Dialect /k/ is older than Middle Korean 'ㅇ' in the correspondence of ‘ㅇ’:/k/. Also I demonstrate that a change of *g>*r>?? is eventually phonological /k/>/h/>Ø. *g>*r>?? had been established in a development of Middle Korean ‘ㅇ[??]’. As do so, I demonstrate that the ‘ㅇ’:/k/, /h/:/k correspondence of Middle Korean and Kyeongsang Dialect is the same diachronic change.
