분극처리된 PZT세라믹스에 외부응력을 인가하였을때 인가되는 응력의 방향에 따른 열화기구의 차이를 조사하였다. 그 결과 분극축과 수직으로 응력을 인가할때의 열화현상은 공간전하분극의 확산으로, 분극축과 평행하게 응력을 인가할때는 분역재배열현상으로 설명하였다. 소결체의 입자 크기가 커지면 열화폭이 커짐을 알 수 있었는데 이것은 입자크기에 따른 내부응력의 차이로 해석하였다. The influence of the direction of applied compressive stress on degradation mechanism ofpoled PZT sample was studied. When compressive stress perpendicular to poling direction was appliedon poled PZT sample, the degradation phenomena was explained by the diffusion of space chargepolarization. On the contrary, compressive stress parallel to poling direction was applied, it wasexplained by the rearrangement of 90" domains. As the grain size increased, the degradation phenomenawas promoted. It is attributed to different internal stress due to difference of grain size. of grain size.

Acne, which intrudes the pilosebaceous unit, is a chronic inflammatory disease. The symptom of comedones, papules, pustules, cysts, nodules and scar mainly raise on the face, upper back, shoulder and neck. The cause of acne is the secreting growth of sebum, abnormal follicular keratinization, the form of group of propionibacterium acnes, and the response of inflammation etc. But the original mechanism of the cytobiologic level is exactly not known yet. Chungsangbangpungtang is one of the most frequently used medical treatments for the acne. A study on 25 patients with acne who took Chungsangbangpungtang shows that the oral medication of Chungsangbangpungtang is the best efficient remedy for a person who has acne less than one year without nodules.

Pompholyx is a special vesicular type of hand and foot dermatitis. It is an acute, chronic or recurrent dermatosis of the fingers, palms and soles, characterized by a sudden onset of many deep-seated pruritic clear vesicles. We diagnosed a patient with pompholyx as damp heat and treated with wet dressing by gauze soaked in distilled solution of Gamihwangryunhaedok-tang(Jiaweihuanglianjiedu-tang). After treatment with wet dressing, we observed the improvement. Based on this study, it is considered that wet dressing with Gamihwangryunhaedok-tang(Jiaweihuanglianjiedu-tang) can be applied to the treatment of pompholyx.

Purpose: To evaluate ocular risk factors related to asymmetric visual field defects in normal tension glaucoma (NTG). Methods: We retrospectively evaluated 92 NTG patients (184 eyes) with asymmetric visual field defects; these patients were classified as having more affected eye (ME) group or less affected eye (LE) group. The differences between ME and LE based on the intra-individual comparison were assessed with several ocular risk factors such as best corrected visual acuity, refractive error, intraocular pressure (IOP), the number of glaucoma medications, disc hemorrhage, central corneal thickness, zone β of peripapillary atrophy (PPA), and disc size. All subjects were divided into two groups according to the severity of bilateral mean deviation (MD, Δ6dB) and evaluated. Results: The MD was -11.2±6.5 in the ME group, and -5.9±5.4 in the LE group (p=0.00). The optic disc size was 2.62±0.8 in the ME group, 2.48±0.5 in the LE group (p=0.00), and there were no statistically significant differences in the other factors. Regarding the difference in the MD, the optic disc size was statistically significant in the less different group, and the angle of PPA was statistically significant in the more different group (p=0.00 and p=0.01, respectively). Conclusions: The optic disc size is a risk factor related to visual field defects in the ME group and the less affected patients, and the PPA is a risk factor, thought to be associated with ischemia, related to visual field defects in the more affected patients with asymmetric normal tension glaucoma.

본 연구는 학교 및 가정에서 학습자들의 컴퓨터 활용 정도가 과거에 비해 현저히 높아지는 현시점에서 학습자들의 학교와 가정에서의 컴퓨터 활용 시간과 목적에 따라 학습자의 정의적 영역-학습동기, 학습태도, 매체에 대한 자기효능감, 정신건강에 어떠한 영향을 미치는지 분석할 목적으로 수행되었다. 본 연구를 위해 초등학교 6학년 학생 963명을 대상으로 학교와 가정에서의 컴퓨터 활용 실태와 정의적인 특성을 구조화된 설문지를 통해 조사·분석하였다. 연구 결과, 학교와 가정에서 컴퓨터 활용시간과 목적에 따라서 학습동기와 학습태도가 유의미한 차이가 있는 것으로 나타났다. 특히, 가정에서 공부 외의 목적으로 컴퓨터를 사용하는 시간이 많으면 많을수록 학습동기와 학습태도 점수가 모두 낮아지는 경향을 보여주었다. 매체에 대한 자기효능감은 학교에서의 사용시간이 2-3시간정도일 때 가장 높게 나타났으며, 정신건강은 가정에서 공부 외의 다른 목적으로 컴퓨터를 활용한 경우는 그 활용 시간이 많으면 많을수록 정신건강에 부정적인 영향을 주는 것으로 나타났다. 본 연구를 통해 컴퓨터의 활용 시간 및 목적이 학습자들의 정의적 영역에 일정 부분영향을 미치는 것으로 밝혀졌기에 학교와 가정에서의 학생들의 컴퓨터 사용에 대한 교사와 부모의 보다 세심한 지도와 공부 이외의 목적의 컴퓨터 사용에 대한 적절한 통제가 요구된다. This study was conducted to research and analyze how using computers at home and in schools influence learners` affective domain(learning motivation, learning attitude, media self-efficacy and mental health) at this time of increasing importance on computer use. A survey of 963 students from grade 6 in pubic elementary schools was conducted and analyzed. This study indicated the meaningful difference on students` computer usage time and purpose with learning motivation and attitude respectively. As the increase in computer usage time, the score for learning motivation and attitude decreased. The self-efficacy for the computer was at its highest when the students use computers 2 to 3 hours a day. As the time for using computers other than study increases, the scores for learning motivation and attitude decrease. The negative effect on mental health was intensifying as the computer playing increases. Since this study proved that the time spent and purpose of computer usage clearly influence learners` effective domain. Teachers and parents need to give more careful direction of using computer to their students and children.

廣東 粤語와 한국 한자어의 음운 비교 연구 : 入聲韻, 陽聲韻을 중심으로

임진호(Im, Jin-Ho)(任振鎬),김미랑(Kim, Mi-Lang)(金美娘) 대한중국학회 2020 중국학 Vol.73 No.-

주지하다시피 우리말에서 차용해 활용되고 있는 한자음에는 지금까지도 중국 고대한어의 특징이 잘 보존되어 있다. 이러한 인과 관계를 밝히기 위해 지난 연구에서 입성운자를 중심으로 양주방언과 우리말 한자어 입성운미의 대응관계를 살펴 본 바 있으나, 중국은 지역적으로 다양한 민족과 언어가 사용되고 있음을 고려할 때, 중국의 특정 지역만을 가지고 한ㆍ중 양국의 入聲韻을 살피기에는 역부족인 측면이 있다. 이에 본고에서는 광동어에도 고대한어의 입성운과 양성운이 잘 보존되어 있다는 사실에 주목하여 광동어를 중심으로 우리말 한자어의 음운 대응관계를 고찰해 보았다. 이를 위해 본 연구는 먼저 광동어 일명 粤语와 우리말 한자음의 형성을 조사하였고, 그 다음으로 중고음과 粤语의 대표 방언인 廣州話와 우리말 한자어 간의 발음의 대응관계를 정리 및 분석하여 음운학의 연관성을 밝혀보았다. 특히 본 연구는 粤语 중에는 우리말의 한자음과 유사하거나 똑같은 경우가 적지 않은 바 광동지역의 학생들이 우리말을 학습할 때 두 언어 간에 나타나는 음운의 유사성을 인식하고, 이를 토대로 그 대응관계를 이해한다면 보다 쉽게 우리말을 배우는데 도움이 될 것이라고 기대해본다. As everyone knows, Koreans have borrowed and used Chinese characters, and the pronunciation of Korean Chinese characters preserves the characteristics of ancient Chinese. To clarify this causal relationship, a previous study looked at the response between Yangzhou dialect and Sino-Korean word, focusing on Ipseong-coda. However, considering that there are various ethnic groups and dialects in China, studying only certain regions of China is not enough to understand the Ipseong-coda both Korea and China. Therefore, based on the fact that the ancient Chinese word Ipseong-coda and Yangseon-coda are well preserved in Cantonese, this paper studied the phonological correspondence between Cantonese and Sino-Korean word. To this end, this study first examined the formation process of Cantonese and Korean Chinese characters, and then organized and analyzed the response relationship of pronunciation between Mid-ancient Chinese Sounds, Guangzhou-hua, the representative dialect of Cantonese, and Sino-Korean word to find out the association of phonology. In particular, this study is based on the fact that Cantonese is similar to Sino-Korean word, and it is expected that students in Guangdong will be able to learn Korean more easily if they recognize the similarity of phonemes between the two languages and understand the correspondence.

임진호(Jin Ho Yim),김상범(Sang Bum Kim),조응호(Eung Ho Cho),최동욱(Dung Wook Choi) 한국간담췌외과학회 2009 한국간담췌외과학회지 Vol.13 No.3

Background & Purpose : This purpose of this study was to determine the prognostic factors for hepatocellular carcinoma (HCC) in patients who received curative hepatectomies at our institution. Patient and Method : A retrospective analysis was performed on 457 patients who had undergone hepatectomies between Mar 1987 and Feb 2008 for HCC at the Korea Cancer Center Hospital, Seoul, Korea. The number of males enrolled in the study was 366 and the numbr of fenales enrolled was 91. The mean age of the patients was 52.8 years old. Hepatitis B virus-related disease was the most frequent etiology (335/457 patients). Two hundred nine(209) patients had liver cirrhosis, and 93.9% of patients were classified in Child-Pugh Class A. Results : The complication rate was 30.6%(140/457) and the operative mortality was 1.5%(7/457). Reoperation was performed in 7 complicated patients. Five-and 10-year overall survival rates of the patients were 57.7% and 41.8% respectively. Poor prognostic factors of overall survival were Child B class, Edmonson-Steiner histologic grade 3 or 4, tumor vascular invasion, and postoperative complications. Five-and 10-year disease-free survival rates were 42.7% and 32.5%, respectively. Poor prognostic factors for disease free survival included the following an Edmonson-Steiner histologic grade of 3 or 4, tumor vascular invasion, and postoperative complications. Conclusion : Postoperative complication is independently a poor prognostic factor for overall and disease free survival in our study. We suggest that special care is needed while performing hepatic resections for the treatment of HCC in order to reduce postoperative complications.

문화언어학은 문화학적인 측면에서 언어를 연구하는 학문이라고 할 수 있다. 즉 문화언어학은 언어를 민족의 문화적 패턴과 민족문화의 부호체계로 인식하고 언어형식, 언어구조, 언어운용, 그리고 언어의 변화 배후에 내포된 문화적 함의를 밝히는 것을 그 목적으로 한다. 따라서 이상의 논문에서는 이러한 문화언어학적 이론을 바탕으로 “춘”자에 내재된 상징적 의미와 그 어휘체계에 대한 분석을 통하여 생명에 대한 인간의 갈망과 탐구를 고찰하는 한편, “춘”자에 대한 각 시대의 기록을 통해 당시의 중국민족이 “춘”자에 대한 객관적 인식을 체득하면서 그 인식 과정 중에서 “춘”자에 부여한 함축적 의미와 해석에 대한 이해들을 살펴보았다. 그리고 이러한 연구를 토대로 “춘”자에 투영된 漢민족의 생명의식과 문화의식이 어휘의 발전에 어떻게 기능하고 발전해 왔으며, 또한 영향을 끼쳐왔는가를 구체적인 분석과 함께 체계적인 접근을 시도하였다.

The research and development of curtain wall construction management are very insufficient due to economic difficulty and imbalance of manpower demand and supply of curtain wall construction enterprises. The theoretical consideration of construction productivity was carried out to suggest a necessity of construction prediction about working days in the domestic construction work, and the necessity of construction period calculation was suggested by understanding the actual condition of the curtain wall construction through characteristics of curtain wall and comparisonㆍanalysis of the present situation. After the working days' prediction method of the existing curtain wall construction was classified into regression analysis, factor analysis and hierarchical multiple regression analysis and considered to establish a prediction model to be suggested in the present study, a regression model process was established by selecting regression analysis as an analysis method using an objective quantified numerical value, and thus the working days' prediction model was built by setting an architectural area, working manpower, the number of total floors as an influence factor affecting major variables of working days' prediction of the curtain wall construction. It is expected that it will be helpful for a curtain wall construction builder to set up a proper construction period through the predicting regression mode in the construction planning stage.
