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

신승용(Shin, Seung-yong) 한국어문학회 2016 語文學 Vol.0 No.132

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.

영어 차용어의 자음 대응 원칙에 대한 고찰

This thesis aims for investigating Korean and English consonants correspondence in English loanwords. Korean and English differ in the consonant inventory. For this reason, when an English sound which is not a phoneme in Korean, it is borrowed as the closest sound in Korean inventory. Loanwords also undergo Korean phonological rules after borrowed. This paper deals with phonological phenomenon in loanwords. A sound which is a phoneme in English, but is allophone in Korean. Some of these sound which are not distinctive in Korean can be perceived by Korean speakers. I will demonstrate these cases in English loanwords. I claim that Korean phonology must account for these sounds.

'ㅓ'[??] 원순모음화 현상 연구 : 경북방언을 대상으로

신승용 국어학회 2004 국어학 Vol.0 No.44

본고는 경북방언에서 나타나는 /?/ 원순모음화 현상의 양상과 특성을 모음체계의 변화라는 사건과의 관련성 속에서 고찰한 것이다. 경북방언의 모음체계는 /ㅡ/와 /ㅓ/, /ㅔ/와 /ㅐ/의 합류로 /ㅣ, E, ㅡ, ?, ㅗ, ㅜ/의 3단 2계의 6모음 체계로 변화하였다. 이로 인해 후설에서 /?/가 /ㅜ/와 [round] 자질에 의해 새로운 대립 관계를 형성하게 되었는데, 이것이 /?/ 원순모음화가 나타날 수 있는 일차적인 조건이 되었다. 하지만 음성적으로는 아직 /ㅏ/가 원래의 [+low] 위치에 머물러 있음으로 인해, 모음체계 내에서 /?/가 온전히 [+high] 위치로 올라가지 못하여 /ㅜ/와 안정적인 대립 관계를 정립하지 못하였다. 이로 인해 /?/는 부분적으로 /o/와도 대립하는 현상을 동시에 가지고 있다. 이러한 까닭에 형태소 경계에서 원래 ‘-으X’ 계열이었던 어미에서만 /?/ 원순모음화가 적용되고, 원래 ‘-어X’ 계열이었던 어미에서는 /?/ 원순모음화가 저지된다. 또한 형태소 내부의 /?/ 원순모음화가 어휘에 따라 수의적으로 적용되는 것도 바로 이러한 이유에서이다. 그리고 /?/ 원순모음화는 형태소 경계에서 형태소 내부로 확대되었기 때문에, 형태소 내부에서의 /?/ 원순모음화도 여전히 공시적으로 작동하는 공시적 규칙이다 This thesis aims for investigating characteristics of /??/ labialization in Kyeongbuk dialect. The vowel system of Kyeongbuk dialect is six vowel as /i, E, i, ??, o, u/, because /i/ and /??/ merged with /??/, /e/ and /ε/ merged with /E/. As the result of this change of vowel system, /??/ is opposed to /u/ in [back]. This is caused to appearance of /??/ labialization. But /??/ isn't opposed with /u/ perfectly in viewpointing phonetics, because /a/ is placed in [+low]. As this fact, /??/ is opposed with /o/ partially. As this reason, /??/ labialization is applied with originally '-iX' ending, but isn't applied with originally '-??X' ending in morpheme boundary, and is optionally applied with the inner morpheme in accordance with the lexicon. As considering /??/ labialization is extended from morpheme boundary to the inner morpheme, /??/ labializaion of the inner morpheme as well as morpheme boundary must be a synchronic phenomenon.

정신분열병에 대한 Risperidone의 효과 및 안전성에 관하여

신석철,왕성근,지익성,이선우,이규광,이봉희,이진영,황선희,신용재,배경도,김정란 충남대학교 의과대학 지역사회의학연구소 1997 충남의대잡지 Vol.24 No.1

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.

Pulpose : Osteeochondroma is a common benign tumor of the axial skeleton, especially the distal metaphysis of the femur and the proximal metaphysis of the tibia, however, is\ occured rarely on the facial skeleton. Tumors of the mandibular condyle are various and rare. so common interest is a little and its clinical symptoms are similar to the others. therefore, early diagnosis is very difficult. In this study, we will present our cases and review the literatures. Patients and Methods: We studied 17 patients(8 males, 9 females) who were diagnosed a osteochondroma of the mandibular condyle in the department of oral and maxillofacial surgery, Pusan National University Hospital. We reviewed the medical records. Results : Patients' mean age was 30.05 years. The sexual distribution is almost same. Twelve left condyles and five right condyles were involeved. The main symptoms was noise and facial asymmetry. Conclusion : Osteeochondroma is a rare benign tumor of the mandibular condyle. The differential diagnosis is difficult. However, using CT and MRI, we diagnosed early the osteochondroma and treated properly. Thus, we presented the cases of the osteochondroma with the literature reviews.

탄산칼슘 폐슬러지와 유리폐기물 재활용 방안

신대용,김승겸 강원대학교 부설 석재복합신소재 제품연구센터 2002 석재연 논문집 Vol.7 No.-

폐유리분말과 탄산칼슘슬러지에 의한 환경문제와 폐기되는 자원의 활용문제를 해결하기 위하여 수질정화용 다공질 담체를 제조하여 물리·기계적 특성을 조사하였다. 50∼90wt%의 폐유리분말과 10∼50wt%의 탄산칼슘슬러지를 첨가한 시편은 탄산칼슘슬러지의 첨가량이 감소하고 소성온도가 증가함에 따라 부피비중과 압축강도는 증가하였으나 기공률과 흡수율은 감소하였다. 900℃에서 2시간 소성한 시편의 부피비중은 1.78∼1.98, 기공률은 11∼65.4%, 흡수율은 14.4∼85.4%, 비표면적은 34∼231㎡/g, 압축강도가 43∼188kgf/㎠이었으며, SEM으로부터 관찰한 시편 내 기공의 크기가 50㎛이상으로 미생물의 서식처로서 적단한 기공크기를 갖고 있어 수질정화용 세라믹스 담체로서 사용이 가능하였다. Porous materials for water purifier were synthesized with waste glass powder and calcium carbonate sludge at 900℃, and their physical and mechanical properties were invetsigated by XRF, BET, XRD, SEM bulk density, porosity, water absoption and compressive strength. The bulk density and compressive strength of the sintered bodies at 900℃ made from 50∼90 wt% of waste glass powder and 10∼50 wt% of calciumcarbonate sludge which were about 1.78∼1.98, and 43∼188 kgf/㎠. From the water absorption and porosity analysis of the sintered materials, a increase of porosity and water absorption were observed with increasing the calciumcarbonate sludge content in raw materials, water absorption and porosity were 14.4∼85.4% and 11∼65.4%. Pore of about 50 ㎛ were produced in porous sintered materials. In this study, it was shown that the porous sintered materials have a good performance of water-purifier with many pores and an adequate strength.
