Background/Aims: Hepatolithiasis or primary intrahepatic stones may be accompanied later by intrahepatic cholangiocarcinoma. This cancerous lesion is frequently associated with atypical hyperplastic epithelium that was suspected of being precancerous. To investigate the Ki-ras or p53 mutation may play a role in carcinogenesis, and to determine whether atypical hyperplastic epithelium may be precancerous, this study was performed in intrahepatic cholangiocarcinomas associated with hepatolithiasis. Methods: We examined 12 patients with intrahepatic cholangiocarcinomas associated with hepatolithiasis. Ki-ras point mutations were assessed by direct DNA sequencing. Expressions of p53 protein were immunohistochemically assessed. The overexpression of p53 and point mutation of Ki-ras were examined in normal, hyperplastic, atypical hyperplastic, and can- cerous tissues separately. Results: The expressions of p53 protein were detected in 4 (33%) of 12 cholangiocarcinomas and Ki-ras point mutations at codon 12 were found in 2 (17%) of 12 cholangiocarcinomas. In those two carcinoma cases which contained the mutant sequence of Ki-ras, the same point mutation from wild type GGT (glycine) to GAT (aspartic acid) was. found in the associated atypical hyperplastic epithelium. However, none of the normal and hyperplastic epithelium harbored Ki-ras or p53 mutations. Conclusions: The overexpression of p53 may play a part in the carcinogenesis of some intrahepatic cholangiocarcinomas associated with hepatolithiasis, whereas the role of Ki-ras mutations in those cases is dubious. However, Ki-ras point mutation at codon 12 may be responsible for either cancer or atypical hyperplastic epithelium associated with hepatolithiasis in certain cases, suggesting atypical hyperplastic epithelium may give rise to carcinoma.

Phonology-Morphology Interaction in Lexical Phonology

Kim, Ki Hwa 대한언어학회 1995 언어학 Vol.3 No.-

Kim, Ki-Hwa(1995).Phonology-Morphology Interaction in Lexical Phonology. Linguistics 3. In this paper a theory of phonology-morphology interaction in Lexical Phonology is proposed. This theory distinguishes two types of phonology in relation to phonology-morphology interaction: cyclic phonology and noncyclic phonology. It is argued that clear distinction between cyclic and noncyclic phonological rules exists and that the domain of noncyclic phonology, different from that of cyclic phonology, is not confined to the lexicon. The validity of the arguments is examined through the analyses of Korean.

Consonant Cluster Simplification in Korean English

Kim, Ki Hwa 대한언어학회 2000 언어학 Vol.8 No.1

Kim, Ki-Hwa. 2000. Consonant Cluster Simplification in Korean English. Linguistics 8-1, 275-295. The purpose of this paper is to examine within the OT framework whether it is possible to predict the CCS of Korean English. The analysis in rule-and-derivation phonology shows that the CCS of Korean English is characterized by extra-vowel insertion regardless of its syllabic constituency, which leads to the assumption that the CCS is the result of filtering English in terms of Korean phonology and of the consonant cluster being simplified. Such assumption enables prediction on the CCS of Korean English within the OT framework, as follows. The CCS, the Korean version of English, is an error pattern caused by assuming different constraint ranking from that of English, and also the result of a transfer of Korean phonology by assuming the Korean language specific constraints.

LMA를 활용한 용산삼개덜머리집 분석

김기화 한국무용연구회 2008 한국무용연구 Vol.26 No.2

This study aims to analyze `Yongsansamgaedeolmeorigip` through LMA(Laban Movement Analysis). To examine the performance, this paper consists of 6 chapters; Body, Effort, Shape, and Space are important instruments in studying the meanings of it. With each scene having conflict or interaction, it makes the climax and comes to its very end. The scene of seduction in the 2nd and 4th chapter employs Proximal Initiation and main movement applied in Rotation shows the voluptuous beauty of woman. Drive is emphasized, by combining Vision Drive with Rotation: use of Passion Drive and immersion of woman`s voluptuous charms makes an easier access to the 5th chapter. Connection structure of Initiation and Simultaneous, Crosslateral pattern of body, and combination of Action Drive lead into the climax. The union of Shaping(Gathering) and Passion Drive represented in the scene of taking off red-colored hansam, a symbol of Yongsansamgaedeolmeorigip, is not as appealing as the early parts. To get a maximal expression, I try to make up the established dance system through Vision Drive Effort and Spoke-like Directional. 본 연구에서는 루돌프 폰 라반(Rudolf von Laban: 1897-1958)의 움직임 분석체계인 LMA를 통해 본 연구자 안무의 1인 무용작품 [용산삼개덜머리집]을 분석하였다. [용산삼개덜머리집]은 분석을 위해 전체 6개의 장면으로 나누어 LMA, 즉 라반움직임분석(Laban Movement Analisis) 이론체계인 신체(Body), 에포트(Effort), 형태(Shape), 공간(Space) 요인을 통해 춤의 내면에 표현되어있는 작품의 의미를 분석하였다. [용산삼개덜머리집]은 각 장면이 서로 다르게 혹은 보완적으로 작용하며 클라이막스를 만들고 이로써 대단원을 갖는 극성(劇性)을 보여주고 있다. 특히 기법적인 면에서 2장과 4장의 Rotation의 기법으로 여성의 관능미를 보여 주고 있다. Drive 역시 2장의 조심스럽게 상대를 응시하는 Vision Drive를 Rotation에 결합하여 강조하였고 공간이 빠진 Passion Drive를 이용하여 자기중심적으로 신체에 몰입하며 만드는 여성의 육체적인 몰입을 통해 뒤이어지는 5장의 갈등으로의 전환을 용이하게 이끌었다. 5장 Distal Initiation과 Simultaneous의 연결구조, Crosslateral한 신체 활용패턴, Action Drive의 결합구조는 갈등적인 격정으로 이끌어지기에 충분하였다. 그러나 5장에서 애첩 용산삼개덜머리집을 상징하는 붉은색 꽃 형태의 한삼을 벗는 장면의 Shaphing(Gathering), Passion Drive의 결합은 앞의 갈등구조를 마무리 짓기에는 너무나 미온적인 에포트와 움직임을 결합하였다.

Many cutaneous reactions have been known to occur within resolved herpes zoster lesions. These include granuloma annulare, pseudolymphoma, lymphoma, granulomatous vasculitis, lichen planus and other dermatoses. The pathogenesis of these reactions remains unclear and it has been proposed that they may represent isotopic response. A dermatomal distribution in lichen planus is very rare. We report here a case of zosteriform lichen planus that was developed on the site previously affected by herpes zoster. (Korean J Dermatol 2004;42(2):217~219)

靈芝버섯 栽培方法 改善에 關한 硏究

金成朝,李甲湘,李基炫,白承和 圓光大學校 1993 論文集 Vol.27 No.2

靈芝載培에 있어서 一般的인 栽培法을 改善하여 靈芝의 收穫量을 높이고 品質向上을 시킬 目的으로 菌絲의 活着條件, 種菌接種 時期 및 方法, 버섯培養地의 土養種類 등을 달리하고, 栽培舍 構造設備을 改良하여 靈芝를 栽培한 結果는 다음과 같다. 種菌接種短木에 菌接種時期가 1月, 12月, 2月, 3月, 4月, 順으로 氣溫이 올라 갈수록 菌絲活着 期間이 빨라져 버섯培養할 때 까지의 菌絲培養 期間을 10日 以上 短縮할 수 있었다. 菌絲培養床의 크기 中 菌絲培養床 幅을 各各 0.8m,1.2m로 하였을 때 같은 菌絲培養期間 동안의 菌絲活着率은 89.6%, 96.4%, 91.2%가 되어 菌絲培養床 幅이 1.0m에서 菌絲活着率이 가장 높았다. 接種短木에 種菌을 接種 後 密封方法은 스치로폴을 막은 後 파라핀으로 密封한 것이 菌絲培養條件에 關係없이 푸른곰팡이 發生率이 가장 낮았고, 스치로폴만 막은것도 新聞紙를 材料로 菌絲培養 條件을 改善하여 푸른곰팡이의 發生率을 파라핀으로 完全히 密封 것과 거의 같은 水準으로 抑制 시킬 수 있었다. 二重 비닐하우스 栽培舍內의 內部 하우스에 遮光幕을 設置함으로서 一般 裁培舍 하우스의 6個月 水準의 靈芝生育 適溫期間을 8個月 以上 까지 延長할 수 있었고, 收穫回數를 年 2回에서 4回로 늘릴 수 있었다. 內部 하우스에 遮光幕을 設置하여 改善한 栽培舍에서는 버섯培養 後 2年次에 目標水準 收穫量의 96.9% 까지 收穫할 수 있었는데 一般 栽培舍에서는 目標 收量의 89.1%만 收穫할 수 있었다. 收穫量에서도 改良 栽培舍의 上品靈芝收量이 一般 載培舍에 比하여 1.5倍의 增收를 보였다. 粘土含量이 가장 많고 모래 含量이 적은 E 土壤에서 雜菌發生이 가장 甚하여 靈芝의 收穫量 및 品質이 가장 低調하였다. To increase the yield and to obtain much better the quality on grown Ganoderma lucidum cultured, these experiments were conducted under carefully controlled in greenhouse with the following conditions on spawn spread related with tentative planting time of short timber inoculated, sealing methods with styrofoam only used and with sealing wax after styrofoam used, soil textures of planting sites, temperatures and growing time as the outside shield was commonly culture method and the inside shield was one of the methods improved itself in these experiments with double vivyl greenhouse. The results were as follow: Speeds of spawn spreading on inoculating Ganoderma lucidum to the short timber were faster when the temperatures were increasing as Jan.<Dec.<Feb.<Mar.<Apr., and it could be short more than 10 days for tentative planting time with inoculation. During the same time of tentative planting the rate of spawn was the highest at the width of 1.0m when the widths of tentative planting hotbets were 0.8, 1.0, and 1.2m, and the rates were 89.6, 96.4, 91.2%, respectively. Occurrences of green mold on inoculated timbers were the lowest as the sealing wax after styrofoam used without the conditions of tentative planting, and when there were surrounding the pile of timbers with styrofoam only used to seal inoculating holes with the second hand newspapers, those were almost the same level as the sealing wax after styrofoam used. When the shield over the roof of the inside greenhouse in the double greenhouse was set, the time on growing could be prolonged until more than 8 months and the yield could be increased 2 times more from 2 to 4 times as compared with the outside shielding over the vinyl that was the common culture method to be known. The culture with inside shielding could improve to be possible that the 96.9% of objective yield was done during two years only and that the amount of the best qualities was 1.5 times than in the common culture, the outside shielding, there was 89.1% of yield only at the same time. In sandy caly that was the least sand and was the most clay of the soils experimented there was the least of yield, there were the plenty of various germs occurred and there was not good in the quality.

부착형 고분자 압전센서를 이용한 탄성파 검출 연구

김기복,윤동진,권재화,이영섭 한국비파괴검사학회 2004 한국비파괴검사학회지 Vol.24 No.3

스마트 구조물에 적합한 탄성파 검출 센서로서 고분자 압전센서를 이용한 부착형 센서에 대한 연구를 수행하였다. PVDF와 P(VDF-TrFE)에 대하여 센서로서의 특성을 평가하였으며 상용화된 PZT 센서와 비교하였다. 음향임피던스가 서로 다른 여러 가지 재료에 고분자 압전센서를 부착하여 연필심 파괴 시 발생하는 탄성파를 검출하여 분석하였다. 센서의 직경이 증가함에 따라 검출 신호의 최대 진폭값은 증가하였으나 센서의 주파수 검출한계는 감소하는 것으로 나타났다. 시편의 음향임피던스가 감소할수록 검출신호의 최대 진폭값은 증가하였으며 주로 저주파수의 주파수 성분의 신호에 민감한 것으로 분석되었다. 전반적으로 P(VDF-TrFE) 센서가 PVDF 센서보다 감도 면에서 다소 양호한 것으로 나타났다. Patch type piezo-polymer sensors for smart structures were experimented to detect elastic wave. The pencil lead braking test was performed to analyze the characteristics of patch-type piezo-polymer sensors such as polyvinyliden fluoride (PVDF) and polyvinylidene fluoride trifluorethylene (P(VDF-TrFE)) for several test specimens with various elastic wave velocities and acoustical impedances. The characteristics of the patch-type piezo-polymer sensor were compared with the commercial PZT acoustic emission (AE) sensor. The vacuum grease and epoxy resin were used as a couplant for the acoustic impedance matching between the sensor and specimen. The peak amplitude of elastic wave increased as the diameter of piezo-film and acoustical impedance of the specimen increased. The frequency detection range of the piezo-film sensors decreased with increasing diameter of the piezo-film sensor. The P(VDF-TrFE) sensor was more sensitive than the PVDF sensor.
