강용관 문화관광연구학회 2001 문화관광연구 Vol.3 No.1

The purpose of this study is to deal with the effective management of foreign exchange for improving profitability of tourism hotel, and specially to aim at the gap between the remittance to foreign banks and the collection from foreign banks. This study analyzed the number of foreigners in each deluxe hotel in Seoul, trade status of foreign exchange, and profit from money exchange. An analysis of remittance status of foreign exchange because of commission payment on the management skill from foreign hotel chains and the cost from hiring foreign general manager proves that first, deluxe hotel in Seoul just do their duties as a purchasing foreign exchange, second, cost rate is too high to exchange into Korean Won because they draw the money from foreign banks after purchasing traveler"s check, and third, there are some needless cost in sending the money to foreign banks which is needed for management of tourism hotel. This study has following limitation. First, there are some errors in collecting data and analyzing status because of statistics of the amount of money exchange is not computerized. Second, research objective is restricted as deluxe hotels only in Seoul. Third, American dollar is the key currency in many countries, so there are a lot of difficulties in analyzing status for the scope of money exchange. So, a study that can minimizes errors in collecting data is required and systematic and steady study is urgently needed.

권용일,권순석 東亞大學校 大學院 1995 大學院論文集 Vol.20 No.-

This study is investigated for predicting a comfort region in the rectangular enclosure assumed Ondol cavity. Thermal environment is actually a combination of air temperature, mean radiant temperature, air velocity, humidity and two personal factors(clothing insulation and activity level) that will influence a person's perception of warmth or coolness. A comfort region is predicted by obtaining operative temperature(OT). The operative temperature is related with radiant and convective heat flux. The operative temperature of comfort region(thermal neutrality) is 20-24℃ at clo=0.1, met=1.2, RH=0%, -0.5<PMV<0.5 and PPD<10%. Radiant and convective heat flux is obtained for various adiabatic walls. This study is carried out a two dimensional numerical analysis by SIMPLER method. Radiant heat flux is obtained by a simplified zone analysis method. And shape factor is obtained by direct integral method.

Oscar Wilde의 이중성 : The Picture of Dorian Gray

李龍官 水原大學校 1991 論文集 Vol.9 No.-

Oscar Wilde의 The Picture of Dorian Gray를 단순히 19세기 말을 풍미했던 유미주의 전통에서만 바라보려고 하는 시도는 위험하기 짝이 없다. 그 이유는 이 작품이 Wilde의 예술 이론과 실제 사이의 간극을 보여주고 있기 때문이다. Wilde는 작품 속에서 자신의 유미주의적 미학관을 설과하지만, 그와 동시에 Dorian과 그가 처할 숙명 그리고 Basil Hallward와 그가 처할 숙명을 통해 아름다움에만 내어 달리는 여술가는 결국 파멸할 수 밖에 없다는 역설적 메시지를 남긴다. 이와 같은 Wilde의 이중성은 새로운 예술에 대한 그의 변증법적 추구를 암시한다. Wilde는 당시의 속된 사실주의와 도덕이란 굴레에서 벗어나고 있지 못하고 있는 빅토리아 조 문학에 깊은 반발을 느꼈다. 그러한 문학은 절대적인 가치와 질서가 붕괴되고, 삶의 의미가 살실된 시대에 사느 인간들을 제대로 조명해 낼 수 없기 때문이었다. 그는 예술가의 상상력이 새로운 실재를 조직할 수 있으리라 믿었다. 이와같은 Wilde의 예술을 통한 실재 추구는 Frank Kermode가 모더니즘의 기본 특성을 밝힐 때 실재가 바로 허구 이고 허구가 곧 실제 라고 했던것과 그 맥을 같이한다.

朴鏞寬,金正浩,李載亨,兪榮植 成均館大學校 科學技術硏究所 1995 論文集 Vol.46 No.1

In this study, the CdS/(p)Si solar cell was fabricated by electron-beam evaporation method, and their properties were investigated. Also the resistivity and optical transmission of CdS thin film were measured. The relation between this results and solar cell characteristics was considered, and came to as follow conclusion. 1. CdS this film is the polycrystalline in direction of (002), and has the hexagonal structure. In proportion to increase of substrate and annealing temperature, the optical band gap, and therefore the photo-transmittance in the absorption edge increases, while conductivity above the critical conditions decreases. 2. In proportion to Indium concentration, the resistivity of CdS thin film is the lowest when Indium concentration is 2[wt%]. In the photo-transmittance for the whole visible light, when the concentration is 2 [wt%], Burstein- Moss shift is the largest. 3. I_SC, V_OC FF, η, display the maximum value when the annealing temperture is at 350[℃]. 4. The characterisitcs of solar cells, that is I_SC V_OC FF, η, fabricated by mixture with In, somewhat more increases than those which is not mixed with. 5. In the optimal conditions the I-V characterisitics of the fabricated CdS/(p)Si solar cells shows as follows. V_OC:450[mV], I_SC:11.5[mA/㎠'], FF:0.475, η:4.92[%]

인간 모델과 정신 요인

이관용,이태연 서울大學校 社會科學大學 心理科學硏究所 1996 心理科學 Vol.5 No.1

정신 모델은 개념적 모호성에도 불구하고 다양한 분야에 적용될 수 있는 유용한 개념이다. 정신 모델은 사람들로 하여금 세상을 이해하고, 행위의 결과를 예측하며, 예측하지 못한 현상들을 다룰 수 있게 해준다. 그렇기 때문에 정신 모델은 심리학 분야와 공학 분야에서 주목을 받고 있지만 심리학에서는 과제 영역에, 공학 분야에서는 도구 영역에 주로 관심을 갖고 연구하여 왔으므로 정신 모델에 대한 체계적 설명이 어려웠다. 본 연구는 정신 모델, 개념 모델 및 시스템 이미지의 세 측면에서 정신 모델을 설명하였다. 그리고 정신 모델이 정보의 표집 방략, 부합성 및 훈련 분야에 어떤 영향을 미치는지를 검토함으로써 정신 모델이 인간공학적 측면에 미치는 영향을 살펴보았다. 그리고 시스템 구조의 사상 과정이 정신 모델과 시스템 간의 관계를 설명할 수 있는지를 검토하기 위해 유추에 대한 구조 사상 이론을 살펴보았다.ABSTRACTThe mental model helps people to understand the affaris of world, expects results of their behaviors, and treats unexpected events. So, there has been increasing interests in psychology and engineering domains. However, the conceptualization of mental model is still left unresolved because psychologists take an interest in task domain while engineers do in tool domain. In this study, the mental model is explained in terms of user's mental model, scientist's conceptual model, and system image. We reviewed how the mental model influences human behaviors by investigating several human factor areas such as sampling strategy, compatibility, and training. And the structure mapping theory of analogy and Gentner &Gentner's study(1983) are analyzed to examine whether the relation between the mental model and system could be explained by mapping processes between base system and target system. In conclusion, although the mental model is vague conceptually, its application in several human factor domains can be useful once clear conceptual models are invented.

金寬洙,李龍保 朝鮮大學校 1977 綜合論文集 Vol.1977 No.-

Robinia Pseudoacacia L.에서 樹高와 年輪에 關係된 纖維길이를 測定해 본 結果는 다음과 같다. 1. 樹高別로 測定한 纖維길이는 一般的으로 뿌리쪽에 가까운 곳이 平均 纖維길이가 짧아지는 傾向이 있으나 同一한 年輪?? 內에서 纖維의 길이의 有意性은 결코 認定되지 않았다. 2. 年輪들 間에서는 1% 이상의 有意性이 認定되었고 pith에서 가까운 쪽의 纖維길이가 가장 짧고 pith에서 점점 벌어질수록 纖維길이가 길어지는 경향을 나타내었다. This study has measured the fiber length in relation tothe tree height and annual rings in Robinia Pseudoacacia L. The results are as follows; 1. It was found that fiber length has a tendency to be shorter than average near the roots, but equal annual ring stuge is not confimed about the significant in fiber length. 2. The fiber length measured at each annual ring is confimed to be over 1% in significant, also near the pith the fiber length is the shortestand they are apt to longer farther from it.

Modern Dramaturgy: Chekhov's The Three Sisters and O'Neill's Long Day's Journey into Night

李龍官 水原大學校 1997 論文集 Vol.15 No.-

본 논문의 목적은 소위 Ibsen에게서 비롯되었다고 간주되는 현대극이 Chekhov을 거쳐 O'Neill에 이르기까지 어떠한 극적 기법의 변화와 차이를 보이고 있는가를 고찰하기 위함이다. Chekhov의 The Three Sister와 O'Neill의 Long Day's Journey into Night는 아리스토텔레스적 전통에 입각한 Ibsen극과는 달리, 잘 짜여진 외부구조를 갖고 있지 않다. 그러나 그것들은 외견상, 산만한 외부구조를 각기 독특한 내부구조로서 극복한다. Long Day's Journey into Night는 시각적인 꿈과 안개의 내부구조, The Three Sister는 청각적인 음향효과의 내부구조를 사용하여 과거, 현재, 미래의 시제를 자유로이 넘나든다. 본고는 이러한 내부구조를 조성하는 요소들이 어떻게 효과적으로 어우러져서 극적 효과를 자아내는지 연구한다.
