Experiments in low strain rate methane-air counterflow diffusion flames diluted with $CO_2$ have been conducted to investigate the flame extinction behavior and edge flame oscillation in which flame length is less than the burner diameter and thus lateral conductive heat loss in addition to radiative loss could be remarkable at low global strain rates. The critical mole fraction at flame extinction is examined in terms of velocity ratio and global strain rate. It is seen that flame length is closely relevant to lateral heat loss, and this sheets flame extinction and edge flame oscillation considerably. Lateral heat loss causes flame oscillation even at fuel Lewis number less than unity. Edge flame oscillations are categorized into three: a growing-, a harmonic- and a decaying-oscillation mode. Onset conditions of the edge flame oscillation and the relevant modes are examined with global strain rate and $CO_2$ mole fraction in fuel stream. A flame stability map based on the flame oscillation modes is also provided at low strain rate flames.

A theoretical analysis on the heat and mass transfer in an evaporative cooler is presented in this work. The evaporative cooler is modeled as a channel filled with porous media the interstitial surface of which is covered by thin water film. Assuming that the Lewis number is unity and the water vapor saturation curve is linear, exact solutions to the energy and vapor concentration equations are obtained. Based on the exact solutions, the characteristics of the heat and mass transfer in the evaporative cooler are investigated. The comparison of the cooling performance between the evaporative cooler and the usual sensible heat exchanger is also carried out. Obviously, the evaporative heat exchanger shows better cooling performance than the sensible heat exchanger. This is due to the latent heat of water vaporization, which results in apparent increases both in the interstitial heat transfer coefficient and the specific heat of the air stream in the evaporative cooler.

공학적 측면에서 확률론적 액상화 재해 작성법이 점차 요구됨에 따라, 본 연구에서는 실제 액상화 피해 현장의 액상화 가능 지수(Liquefaction Potential Index, LPI)를 이용한 로지스틱 회귀분석으로 액상화 피해 확률을 예측하였다. 또한 이 분석을 바탕으로 광역지역의 액상화 재해도 기법을 제시하였다. 사례 연구로서 미국 세인트루이스 지역 홍수평야의 표준관입시험(273 곳) 결과를 대상으로 LPI를 산정하였고 최대지반가속도를 코크리깅의 이차변수로 적용하여 보간하였다. 연구결과, 일부 구역에서 연약지반과 얕은 지하수위로 인해 LPI 값이 5이상으로 나타나, 액상화로 인한 지반 피해 확률이 0.5 이상으로 예측되었다.

The purpose of this study is to analyze the characteristics of structural expression in the works of Louis I. Kahn. Kahn's main architectural thoughts of 'what it wants to be' and 'how it was done' are important in this research because these statements act as a clue to understand the relationship between structural expression and space. 'What it wants to be' means the essence and existence of architecture and 'how it was done' shows the tectonic of architecture and construction process to enhance its presence. Kahn's emphasis of structural expression stems from the fact that structure is the logical part of whole building system rather than the concealed object for the exterior of buildings. Therefore structure of Kahn's architecture is not a structure only to support building but a mean to express his thoughts in a corporeal way. In Kahn's works, the characteristics of structural expressions are summarized as the visualization of the order in dynamics, construction process, spatial system, and the relationship between structure and light in the space.

The purpose of this study is to analyze the meaning of 'dis-joint' in the works of Louis I. Kahn. Kahn tried to realize his main architectural thoughts of 'what it wants to be' and 'how it was done' through his whole life. The concept of 'dis-joint' had been developed to visualize his architectural thoughts. Kahn used' dis-joint' to show and emphasize the structural system for the raison d'etre of building. Kahn's 'dis-joint' can be categorized as 'spacing', 'butt', 'slit' and 'protrusion'. Kahn used this kind of unusual way of joint beyond simple exposure to stress the existence of element, part and building itself. Through variable combination usage of 'dis-joint', Kahn can realize his architectural thoughts into building in a concrete way. The efficiency and function of joint is not the main issue in his works. 'Dis-joint' was the concrete tool to show the tectonic of architecture and construction process to enhance its presence. Therefore 'dis-joint' of Kahn's architecture is not a joint only to combine building parts but a concrete mean to realize his thoughts in a corporeal way. These facts insinuate that Kahn's architectural philosophy is based on the thoughts of tectonic and its realization.

One of the most notable architectural aphorisms in modern period must be undeniably Louis Sullivan's, 'Form Follows Function.' The aphorism has been not only an important source of new aesthetic but also an formal principle of machine age. Other most famous source in order to justify modern aesthetic was the short essay by an cynical critic, Adolf Loos(1870-1933), 'Ornament and Crime' of 1908. Apart from what the essay asserted it is also famous for the influence of Sullivan's architectural notion during Loos' States staying. For Architectural historians of the early 20th century this connection is so useful to create a legacy of modern architecture. The historians seemed to believe that Loos understanded Sullivan's aphorism on which the historians wanted to focused. When we however look into two buildings designed and built in the period of publishing both aphorism and essay there must be a big fissure between the buildings and the historians interpretations. With this view point this study aims at showing the true meanings of Sullivan's aphorism and Loos' essay and also the big difference between the machine age's aesthetic and theirs.

Objective: Undernutrition is common amongst esophageal cancer patients and therefore appropriate nutrition support is critical. Nevertheless, the effectiveness of enteral nutrition (EN) versus parenteral nutrition (PN) is still controversial. The aim of this study was to investigate the effect of EN and PN on the nutritional state and the length of hospital stay for patients who underwent an Ivor-Lewis (IL) esophagectomy. Method: A retrospective clinical analysis was performed that utilized the electronic medical records of patients who underwent IL esophagectomy during a 3-year period between January 2010 and December 2012 at a tertiary teaching hospital located in Seoul, Korea. The EN group and PN group were analyzed by comparing the nutrition supply, postoperative complications, length of hospital stay, and weight variation. Results: After an IL esophagectomy, the complication rate between the EN group and PN group was insignificant and the length of hospital stay was significantly shorter for the PN group compared to the EN group (14 vs. 16 days, respectively; p<0.001). At the time of discharge, those in the PN group lost less weight postoperatively (p=0.003). Conclusion: PN may be considered as safe nutrition support for esophageal cancer patients who underwent an esophagectomy.

The fireplace has been inseparable from the wall. Therefore, the fireplace, which is independently revealed in the living room, is unusual and exceptional. According to the concept of "Served-Servant space" by Louis Kahn, "Servant space" is conceived as an inhabited thick wall and completely separated from "Served space." The fireplace is an apparent servant element, but in Fisher house, it is considered as the single, remarkable and major element composing the house. Paradoxically, this scene of the living room is in conflict with Kahn's ideas on "Servant space." This study sheds new light on the independent fireplace in the conflicting relationship and suggests the similarities with the contemporary cases-Le Corbusier & Philip Johnson-in terms of the stand-alone "Servant element." In the end, the independent fireplace of the Fisher house has transformed into an essential element of the house, as Kahn said that "I feel it[fireplace] represents the presence of a man and therefore is of home."
