임경은,황대준 成均館大學校 科學技術硏究所 1995 論文集 Vol.46 No.1

Creating collaborative environment on heterogeneous PC-based multimedia platforms running on different operationg systems has been of great importance to allow natural interaction among remote users through interoperability. Intelligent Mirroring is incorporated into our Multimedia Distance Learning System for IBM PCs and Apple's Power Macintoshs running Windows (ver. 3.1, ver. 95) and System (ver. 7.1, ver. 7.5), respectively. Upon messages from platforms via Ethernet involved the distance learning situation, Intelligent Mirroring its functions based on system homogeniety: liasion of messages for homogeneous platforms, interpretation of events and conversion of data encoding formats for heterogeneous platforms involved in the interaction. In such a distance learning situation requiring high degree of interaction Intelligent Mirroring contributes not only to establishing function and content sharing at a fine grain level with low cost, but also to minimize traffics related to interpretation of events to be shared by platforms participating in the collaboration.

임은경,최영철 大韓小兒齒科學會 1998 大韓小兒齒科學會誌 Vol.25 No.4

The intention of this study was to investigate the preventive effect of chlorhexidine varnish on enamel demineralization. The sample consisted of 57 first premolars scheduled to be extracted for orthodontic purposes. The control group (N=10) was left untreated and the experimental groups were worn with specially designed stainless steel orthodotic bands on premolar for plaque accumulation. The group(N=9) was worn band only, the group 2 (N=19) was applied with chlorhexidine varnish for one time, and the group 3(N=19)was applied with chlorhexidine varnish for 3 times once a week. After 4 weeks of experimental periods, every specimenwere examined by SEM and Vickers hardness test to evaluate and compare the degree of enamel decalcification. The results were as follows: 1. Although SEM revealed various degree of enamel demineralization in every experimental groups, the group 1 showed more severe demineralizations than the group 2and 3. 2. The mean Vickers Hardness Numbers measured in this study seemed to reveal that there was a statistically significant difference between the control goup and the group 1 (p<0.05), and also a significant defference between the group 1 and the group 2,3(p<0.05). And there was no significant difference between the group 2 and the group 3 (P>0.05). 3. The results of VHN did not deemed to show a statistically significant difference between maxillary premolar and mandibular premolar in both group 2 and group 3 (p>0.05).

호흡기능 또는 근기능이 얼굴의 구조적 관계에 미치는 영향을 평가하고자 어려서부터 한가지 운동종목을 전공하여 온 체육대학 학생 137명을 운동의 유형에 따라, 지속적으로 심폐지구력이 많이 요구되는 운동군(1군), 심폐지구력이 많이 요구되기는 하나 1군보다는 적게 요구되는 운동군(2군), 그리고 순간적인 근력이 크게 요구되는 운동군(3군)으로 분류하고, 정모 및 측모 방사선사진을 계측학적으로 평가하여 다음과 같은 결론을 얻었다. 1. 머리너비길이지수는 모두 단두개에 속하였으며, 각 군간에 유의한 차이가 없었다(p>0.05). 2. 1군과 2군의 얼굴지수는 유의한 차이가 없었으나(p>0.05), 1군과 3군간, 2군과 3군간에는 현저한 차이가 있었다(p>0.05). 3. 얼굴지수와 높은 상관관계를 지닌 각 군의 계측항목은 전하안면높이(상관계수: 0.63∼0.69, p>0.001, 총안면높이, 전상치조높이, 전하치조높이 및 총안면두기높이 등이었다. 4. 3군의 두 개계측치는 전면안면높이(상관계수: 0.36∼0.55, p>0.001) 및 전하안면높이(상관계수: 0.31∼0.56, p>0.001)와 높은 상관관계를 나타냈다. 5. 1군과 2군은 얼굴의 수직 계측치가 전반적으로 컸고, 3군은 수평 계측치가 크게 나타나는 경향을 보였다. The purpose of this study was to investigate differences in craniofacial characteristics of professional sportsmen who have practiced since their prepubertal periods. From the standardized lateral and P-A cephalograms of 137 aportsmen, 7 angular, 19 linear, 4 ratio, and 2 index measurements were measured and evaluated by means of statistical methods. The samples were divided into three groups: Group 1; ice hockey(n=17), football(n=27), basketball(n=16), Group 2; baseball(n=16), gymnastics(n=13), and Group 3; judo(n=18), ssireum(n=10), weight lift(n=20). The results were as follows: It seemed obvious that the cephalic indices of the 3 groups exhibited brachycephalic headform (Group 1; 0.85±0.04, Group 2; 0.85±0.04, Group 3; 0.83±0.06) and there was no statistical difference among the groups(p>0.05). The facial indices of the Group 1 (0.93±0.05) and Group 2 (0.93±0.04) exhibited difinite leptoprosopic facial forms while the Group 3 (0.90±0.04) showed more or less euryprosopic facial form, and there appeared significant difference between the Group 1 and 3 (p<0.05), and also between the Group 2 and 3 (p<0.05). There appeared strong relationships between the facial indices and the facial axis angle, mandibular plane angle, total craniofacial height, total facial height, upper anterior dental height, lower anterior dental height, mandibular length, lower anterior facial height ratio, and especially with lower anterior facial height (p<0.01). It seemed that more of the vertical facial measurements of the Group 1 and 2 appeared to be larger than those of the Group 3.

林龍進,민경은 慶北大學校 1978 論文集 Vol.25-26 No.-

The solubilities of benzene in water and aqueous urea solution were determined by an ultraviolet method at various temperatures between 0°and 40℃. Solubility minimums, ΔH_sol _min corresponding to a zero heat of solution appeared in 1∼3 M aqueous urea solution as well as in water, and they were shifted to lower temperature side in accordance with the increase of urea concentration. Calculated transfer thermodynamic parameters of benzene from water to urea solution and solubility mininmums were interpreted in terms of iceberg formation in solution and also support the concept that urea acts like a structure breaker in water.

This study was carried out to improve the qualities and extend the shelf life ot Yukwa and Salyeotgangjung. traditional Korean cookies, using tine hot salt instead of oil as the popping medium. The Yukwa and Salyeotgangjtmg that had been popped using tine salt were stored at 25?for one or two months, and then compared their sensory evaluation, lipid contents and acid and peroxide values with those popped in oil. In the sensory test, the Yukwa base and popped rice expanded in the salts and stored for one month were preferred to those expanded in oil with regard to flavor and overall acceptability. With respect to the whiteness, off-flavor, and crispness, these properties those expanded in salt had stronger whiteness and crispness but a weaker off-flavor compared to those expanded in oil. The lipid contents of the Yukwa base and popped rice expanded in oil were 37.73 and 49.65%, respectively, which were significantly higher than in those expanded in salts (0.10 and 0.53%, respectively). The acid and peroxide values were larger in those expanded oil than in salts after 8 weeks storage. In view of the above results, the conclusion was reached that the Yukwa base and popped rice expanded in salts were less likely to provide a calorie intake and to become rancid over a long storage time.

자질 유인 이론과 조동사 도치 현상

임은경 대전대학교 인문과학연구소 2001 人文科學論文集 Vol.31 No.-

The purpose of this paper is to analyze the auxiliary inversion phenomenon in English interrogative clauses within the framework of the attract-feature theory in the minimalist program. There are basically three types in distribution as the followings auxiliary inversion with overt wh-phrase movement, no auxiliary inversion with overt wh-phrase movement, and no auxiliary inversion without overt wh-phrase movement. To explain the distribution properties, I propose the following: The features of C which should be checked in the course of derivation are Q-affixal feature and wh-feature. Q-affixal feature is divided into two types, verbal affixal feature and non verbal affixal feature, following Kayne (1982). Verbal affixal feature induces the auxiliary inversion or do-support if it is strong. Its strength is determined by overt wh-movement. Whether a wh-phrase is attracted to [Spec, CP] or not is derived automatically in the course of derivation following the economy principle. I have shown my proposal is adequate in that it explains subject and object/adjunct asymmetry in wh-interogative clauses and the differences between matrix and embedded clauses, etc.

Kyung‑Yoon Jeon,Eun‑Ji Ko,Young Lim Oh,Hongbae Kim,Wan Kyu Eo,김아리,Han Gyu Sun,Meesun Ock,Ki Hyung Kim,Hee‑Jae Cha 한국유전학회 2020 Genes & Genomics Vol.42 No.10

Background Human endogenous retroviruses (HERVs) constitute around 8% of the human genome and have important roles in human health and disease, including cancers. Previous studies showed that HERV envelope (Env) proteins are highly expressed in cancer tissues and co-related with cancer progression. KAP1 has been reported to play a key role in regulating retrotransposons, including HERV-K, through epigenetic silencing. Objective The relationship between KAP-1 and HERV Envs expressions was analyzed only in tumor cell lines and has not yet been studied in cancer tissues. In this study, we analyzed the expression patterns and relationship between KAP1 and HERV Env proteins in ovarian cancer tissues. Method The expression patterns of KAP-1 and HERV Env proteins, including HERV-K and HERV-R, were analyzed in ovarian cancer tissue microarrays that contained 80 surgical specimens, including normal ovary and malignant ovarian cancers. Results The expression of HERV-R Env and KAP1 proteins is signifcantly higher in ovarian cancer compared with normal ovary tissues. However, the expression of HERV-K Env did not change signifcantly in cancer tissues. The expression patterns of HERV-K Env and HERV-R Env signifcantly increased in early stages of cancer and KAP1 expression was higher in certain stage and types of cancers. However, the expression of HERV-K Env, HERV-R Env, and KAP1 did not change in diferent age groups. The correlation between the expression of KAP1 and HERV-Env, including HERV-K and HERV-R, was not signifcantly correlated. Conclusions The results of this study showed that there was no signifcant correlation between the expression of KAP1 and HERV Env proteins in ovarian cancer tissues, unlike studies with cell lines in vitro. These results suggest that the actual expression of HERV Env proteins in ovarian cancer tissues may be regulated through various complex factors as well as KAP1.

광장공포증 유무에 따른 공황장애 환자의 공존병리와 증상 심각도의 비교 연구

임경희,장은진,김정범 대한생물치료정신의학회 2002 생물치료정신의학 Vol.8 No.2

연구목적 : 본 연구에서는 광장공포증을 동반하지 않은 공황장애 환자들(이하 비광장공포증군)과 광장공포증을 동반한 공황장애 환자들(이하 광장공포증군)의 공존병리와 증상의 심각도를 조사하여 두 질환의 본질을 규명하고 치료계획을 세우는데 도움을 얻고자 한다. 방 법 : 연구대상은 1998년 3월부터 2001년 7월까지 계명대학교 동산의료원 정신과에서 외래치료를 받아온 환자들로 비광장공포증군 26명, 광장공포증군 44명으로 구성된 총 70명이다. 평가도구는 9개의 증상차원을 평가하는 90문항으로 구성된 간이정신진단검사(SCL-90-R)와 공황장애의 필수적이고 전반적인 7가지 영역의 심각도를 평가하는 한국판 공황장애 심각도 척도를 사용하였다. 통계적 분석은 ANOVA, Chi-square test, student t-test, person correlaiton을 시행하였고, 통계적 유의수준은 p<.05로 하였다. 결 과 : 1) 광장공포증군의 광장공포증적 두려움과 회피의 정도는 경도에서 중등도 사이에 해당되는 것으로 나타났다(PDSS점수 : 1.46±0.94). 2) 인구통계학적 특성에 대해 광장공포증군과 비광장공포증군을 비교해 보면, 연령, 성별, 교육정도, 직업유무, 병력, 발병연령에서는 두 집단 간에 유의한 차이가 없었다(표 1). 3) 세 집단의 공존병리의 유형을 분석해 본 결과, 광장공포증군은 모든 증상차원에서 정상대조군 집단보다 유의하게 높은 점수를 얻었다. 비광장공포증군은 불안, 공포불안, 정신증 척도에서 정상대조군 집단 보다 유의하게 높은 점수를 얻었다(표2). 4) 광장공포증군은 비광장공포증군에 비해 신체화, 강박증, 적대감, 공포불안, 편집증척도에서 유의하게 높은 점수를 보였다(표 2). 5) 광장공포증군과 비광장공포증군의 심각도 비교에서는 내적감응적 두려움과 회피, 직무수행의 장해/고통, 사회적 기능의 장해/고통에서는 두 집단 간에 유의한 차이를 보이지 않았느아, 심각도 총점, 복합점수, 공황발작의 빈도, 공황발작 동안의 고통, 예기불안, 광장공포증적 두려움과 회피에서는 광장공포증군이 비광장공포증군에 비해 유의하게 높은 점수를 보였다(표 3). 6) 광장공포증군내에서 광장공포증적 두려움과 회피항목은 SCL-90-R의 정신증 척도를 제외한 신체화, 강박증, 대인민감성, 우울, 불안, 적대감, 공포불안, 편집증 척도와 유의한 정적상관관계를 보였다(표 4). 결 론 : 광장공포증군이 비광장공포증군에 비해 대부분의 필수증상의 심각도가 높을 뿐만 아니라 더 다양한 공존병리를 가지고 있음이 밝혀져 기본적으로 더 심한 질환임이 시사된다. 따라서 공황장애의 치료와 평가에 있어서 공존병리와 증상의 심각도를 함께 고려하고 공황장애에서 광장공포증이 동반되는 경우 이에 대한 더 적극적이고 집중적인 치료가 필요하겠다. Objectives : In this research comorbidity and severity of symptom of patients that have panic disorder without agoraphobia(PD) and with agoraphobia(PDA) were examined in order to study their nature more closely and also to help set up therapy plans. Method : 70 patients were diagnosed with PD(N=26) and PDA(N=44) by DSM-Ⅳ. SCL-90-R was administered to panic subjects and normal control subjects. PDSS were administered to panic subjects, the statistical analysis was conducted using ANOVA, Chi-square test, student t-test, Pearson Correlation analysis. statistical signifi-cance was p<.05. Results : 1) The degree of agoraphobic fear/avoidance of PDA indicated the level to from moderate(PDSS score 1.46 0.94). 2) There was no significant difference between the two groups(PD/PDA) in there sex, age, education level, occupation, duration of illness, onset of age. 3) After analyzing the comorbidity pattern of the three groups, PDA was significantly higher score than normal control group in all symptom level. PD had higher score than normal control groups in anxiety, phobic anxiety and psychotism. 4) PDA showed much a significantly higher score in Somaatization, Obsessive-Compulsive, Hostility, Phobic Anxiety, Paranoid Ideation when compared to PD. 5) There was no significant difference between the two groups(PD/PDA) in there interoceptive fear/avoidance, PDA had significantly higher scores than PD. 6) The agoraphobic fear/avoidance item within PDA had significant correlation with Somatization, Obsessive-Compulsive, Interpersonal Sensitivity, Depression, Anxiety, Hostility, Phobic Anxiety, Paranoid Idation except significant correlation with psychoticism. Conclusion : As it is shown clearly in all the results, PDA had a higher level of severity than PD. It was also clarified that PDA had a variety of comorbidity. Therefore when evaluating the treatment of Panic Disorder, One has to consider the comorbidity and severity. A more positively and concentrated treatment will be needed when panic disorder is accompanied by agoraphobia.
