Kim, Jae-Duk,Kim, Jin-Soo 대한구강악안면방사선학회 2005 Imaging Science in Dentistry Vol.35 No.4

Purpose : To classify and describe the characteristic features of MRI of some ameloblastoma variants. Materials and Methods : The MR images, CT images, and panoramic radiographs in 5 cases were retrospectively examined as follows. First, the contents of ameloblastomas were devided into two portions of either solid or cystic components on the basis of MR signal intensities. The signal intensity within the solid or cystic portions was classified as homogeneous or heterogeneous. Next, the characteristic internal feature of the lesion on T1W1 or T2WI was described. The signal intensities were classified into low, intermediate, slightly high, high, and strong high signal intensity. Results : Unicystic lesion showed homogeneous high signal intensity (SI) on T2W2 and the rim enhancement of the surrounding area including the mural nodule and the thick wall except the central portion on Gd-T1W1 Solid type revealed heterogeneous and high SI area with strong high SI area on T2W2. On Gd-T1W1, the area corresponding to the low signal spot on T1W1 and the strong high signal spot on T2W1 showed low SI. Hybrid type showed slightly enhanced capsular structures and low SI for the round bony septa and the areas connecting the mixed and cystic lesions on T2W1 and Gd-T1W1. Conclusion : MRI could easily assess the relationship between the mixed and cystic findings in ameloblastoma.

The author analyzed the clinical and radiographic findings of 109 malignant tumors of epithelial origin occurred in the jaws of the patients visited the infirmaries of Dentistry. Chosun University and several university in Korea during 1978 to 1988. The observed results were as follows: 1. It appeared that 93% of the total 397 cases diagnosed as oral malignant tumors were squamous cell carcinomas. 2. The incidence ratios between nodular type and ulcer type were 4 to 1 in maxilla and 3 to 1 in mandible. 3. In nearly 50% of all patients complained of pain due to impingement of tumor mass or ulcer. 4. Most of carcinomas of maxilla eventually invaded into maxillary sinus and palate. 5. Characteristic features on the radiographs were the lesion with ill-defined border, the direct destruction of the alveolar bone and anatomical landmark without displacement of the involved teeth and the gray shadow of the tumor mass in the lesion.

고기영어의 자음문자소의 음가에 관한 연구

배재덕 새한영어영문학회 2002 새한영어영문학 Vol.44 No.2

This study focuses on the phonetic values of 16 consonant graphemes which were written on the Old English texts from the 8th century to the 12th century. The phonetic details of the pronunciation of old English consonant graphemes are presented in a phonetic table of Old English consonantal articulations according to Gimson's RP English Phonetic Table. In general, when you read Old English, every spelling symbol must be pronounced. But it will be seen that Old English spelling symbols are ambiguous, since they stand for more than one phoneme; this is true of c, of g, of cg, and sc, and also since one phoneme stands for several allophones. However, when you read Old English texts by having knowledge of each grapheme's phonetic value exactly, most of the spelling symbols are unambiguous and well acquainted with. The Old English Consonantal Articulation Table presented here as a result of this study will surely contribute to the present and future Old English reader. Old English has the following phonemes, and allophones for 16 consonant graphemes. 1) 19 consonant phonemes : /p/, /b/, /t/, /d/, /k/, /g/, /f/, /h/, /r/, /ð/, /s/, /??/, /??/, /??/, /m/, /n/, /l/, /j/, /w/ 2) 14 allophones : ·3 pairs of voiced and voiceless allophones /f/ → [f], [v], /ð/ → [θ], [ð], /s/ → [s], [z] ·several allophones each phoneme /h/ → [h], [c¸], [x], /n/ → [n], [ŋ], /g/ → [g], [j], [w] 3) OE allophones ([v], [ð], [z], [ŋ]) became independent phonemes (/v/, /ð/, /z/, /ŋ/) in modern English.

都市周邊 農村地域의 人口移出現象 : 淸原郡 玉山面의 事例硏究 The Case Study of Oksan

李在德 西原大學校 1984 西原大學 論文集 Vol.13 No.-

In this paper, the writer attempted to identify the problems which came from rural outmigration and to consider the solutions of these problems. It is assumed that these problems are different in every rural areas according to their locational context.The rural areas in the vicinity of city are selected for this study and these are three hamlets in Oksan Myon neighboring Cheongju City (Fig.1).The data were collected by interview with residents in the study area using questionnaire. The analytic procedure for this study is as follows. 1) To see the degree of rural outmigration in the study area,the numbers of migrants and households containing individual migrants are counted and the ratio between migrants and residents are calculated in each study area. 2) The motive,selectivity and destination of outmigration are explained by comparative analysis between migrants and residents in the context of their age, sex, education and income level. 3) From these,the resulting problems are described and some solutions are supposed. In these contexts,the following concluding remarks are made. Study areas experience rural depopulation due to steady outmigration and this reduces the effectiveness of investment for establishments of public facilities and service functions in runal areas.Thus it becomes a hindrance to desirable living of rural residents. Outmigration in study areas also reveal the selectivity of age,sex and education.The age group 20-30 are most highly leaving the rural areas and males are more migratory than females.The more educated,the more migratory. It means the outflow of agricultural labor forces possessing high productivity. Therefore,agriculture is managed by farmers who have low productivity. This results in stagnation of agriculture and low income of rural households in study areas. And thus,economic motive for migration appeared as the most influential one in study area.The stagnation of income results in the delay of agricultural mechanization which seems to be the best method to cope with the lack of labor forces due to financial deficits.Therefore,the rural areas meet with duplicated difficulties. The destination of migrants differ in their motives.These are Seoul Metropolitan Area for occupation and Cheongju City for education respectively. Because Cheongju City cannot offer sufficient employment opportunities,she is not selected as the destination of outmigrants from study areas and commuting to her rarely take place. Thus,I think that the best solutions of these problems are to seek the methods which settle down the rural population in rural areas and which increase the income of farming houscholds.The public investment by government authorities are needed for the improvement of living conditions in rural areas though ineffective.Besides the enhancement of agricultural income through intensive land use,increase of agricultural productivity per unit area,agricultural mechanization etc.,it is desirable in rural areas near the city that rural households get income from nonagricultural sectors to rise their income level.It is possible through that rural residents get a job at neighboring city and commute.For this the regional center which can offer sufficient employment opportunities,public facilities and service functions should be developed within short distance from rural areas.

자궁경부암에서 H-ras의 재배열과 v-mos의 증폭

김재형,함덕상,고복현,김대광 동국대학교 경주대학 1993 東國論集 Vol.12 No.-

Uterine cervical cancer is the most common cancer of woman in Korea. To understand which oncogenes are involved in squamous cell carcinomas of the uterine cervix, author examined nine human tissues of squamous cell carcinomas of the uterine cervix using Southern blotting techniques for five known oncogenes (H-ras, v-mos, erbB2, c-myc, K-ras). One of the nine tumors demonstrated a rearrangement of the H-ras oncogene. And amplification of v-mos was found in three tumors. The other oncogenes(erbB2, c-myc and K-ras) were the same pattern with the control. It is presumed that rearrangement of H-ras and amplifications of v-mos may be concerned to oncogenesis of squamous cell carcinomas of uterine cervix.

박경덕,성재현 대한치과교정학회 1995 대한치과교정학회지 Vol.25 No.3

안면골 성장유형에 따른 두개안면골의 성장양상의 차이를 조사하기 위하여 정상교합자 남자 19명 여자 14명으로부터 8.5세에서 18.5세까지 10년 동안에 걸쳐 촬영한 연속 두부방사선규격사진을 분석 조사하였다. 이 조사에서 안면골 성장유형은 최초 8.5세에서 10년 후인 18.5세 사이의 Y-axis의 총변화량을 기준으로 Drop, Neutral, Forward군으로 구분하였다. 각 군에서 안면 각 부위의 변화를 계측 분석하여 각 유형의 10년간 성장양상의 차이를 조사한 결과는 다음과 같이 요약할 수 있었다. 본 연구에 사용된 대상에서 두개안면골 성장양상의 분포는 Neutral군이 52%, Forward군이 27%, Drop군이 21%로 나타났다. 두개저에 대한 상,하악골의 전방성장은 Forward군이 Drop군에 비해 크게 나타났으며 Neutral군과 Forward군에서 상악에 비해 하악의 전방성장이 크게 나타났다. FH plane에 대한 palaltal plane의 기울기는 연구기간 동안 Forward군이 다른 두 군에 비해 전상방으로 경사되면서 성장하였다. 또한 하악평면은 Forward군이 Drop군에 비해 반시계 방향의 회전이 크게 나타났으며 이런 경향은 남자가 여자보다 크게 나타났다 하악체부(Go-Me)의 길이 성장은 Drop군이 Forward, Neutral군에 비해 작게 나타났다. 본 연구에서 안면골의 성장에 관하여 길이 및 각도적 계측치는 각기 다양하게 나타났으나 수직적 비율의 특성은 각 군에서 비교적 일관성 있게 유지되는 경향을 나타내었다. 이상의 분석자료를 이용하여 교정진단시 개개인의 성장양상을 평가하기 위하여 8.5세에서 18.5세까지 성장유형별 profilogram을 작성 제시하였다. The purpose of this study was to compare the difference of the growth aspects in three facial growth patterns. The biennial serial cephalometric radiographs of 33 samples(19males, 14females) with normal occlusion from 8.5 years to 18.5 years of age were used in this study. The facial growth pattern was categorized in 3 types(Drop type, Neutral type, Forward type) by the total amounts of the Y-axis which changed from 8.5years to 18.5 years of age. The growth change of the craniofacial area during 10 years in each growth type was analyzed and was compared among the 3 growth types. The results of this study might be summarized as follows : 1. The samples that were classified by total change of the Y-axis during this study period were distributed to 52% of the neutral type, 27% of the forward type, 21% of the drop type. 2. The anterior growth of the maxilla to the cranial base(N per A) showed larger in forward type than in other 2 types(p<0.05). 3. The palatal plane to the FH plane showed more anterior-superior inclination in the forward type with age during this study period. 4. The anterior growth of the mandible to the cranial base(N per Pog) appeared large in rank order, of largest the forward type, second the neutral type, and third the drop type(p<0.05). 5. During this study period the mandibular plane(SN/Mn,FMA) showed more counterclockwise rotation in the forward type than in the drop type(p<0.05), and this tendency was stronger in males than in females(p<0.05). 6. The growth of the mandibular corpus length(Go-Me) showed smaller in the drop type than in the other 2 types(p<0.05). 7. In the forward type and the neutral type, the anterior growth of the mandible was larger than that of the maxilla(p<0.05). 8. In the craniofacial growth, distances and angulations turned out to be somewhat variable, but the vertical proportion had a strong tendency whose original relation was maintained consistently during this study period. 9. Through these analyzed data, the profilograms on each growth type were constructed to evaluate individual growth pattern in the orthodontic diagnosis.
