Because stewardesses have to work based on irregular schedule and go abroad, they are assumed to have more conflicts between work and family than other working women. Stewardesses are part of the product and are therefore key front-line players in the tourism industry as they service guests during a journey. This study was to explore the characteristic of Korean stewardesses’s practical use using in-depth interview technique. 10 stewardesses who have more than four year work experiences were conveniently selected and in-depth interviewed from June 2014 to August 2014. The purpose of this study is to explore the characteristics of work among Korean stewardesses in Korea. Qualitative research approach was used to identify significant issues and draw out policy and managerial implications. So the Korean stewardesses’s career development and socialization process are explored. Based on the results, managerial and policy implications and future research directions are discussed.

In general. FDM(finite difference method) and FVM(finite volume method) are used for analyzing the fluid flow numerically. However it is difficult to apply them to problems involving complex geometries. multi-connected domains. and complex boundary conditions. On the contrary. FEM(finite element method) with coordinates transformation for the unstructured grid is effective for the complex geometries. Most of previous studies have used commercial codes such as KIVA or STAR-CD for the flow analyses in the engine cylinder. and these codes are mostly based on the FVM. In the present study. using the FEM for three- dimensional. unsteady and incompressible Navier-Stokes equation. the velocity and pressure fields in the engine cylinder have been numerically analyzed. As a numerical algorithm. fractional step method is used and ALE (arbitrary Lagrangian Eulerian) method is adopted for moving grids

박찬국 서울大學校 人文學硏究所 2003 人文論叢 Vol.50 No.-
It is broadly recognized that the modern technological civilization was made possible on the basis of the modern view of nature which understands the nature as mathematically quantifiable 'res extensa'. Galilei and Descartes, the pioneers of this view of nature, thought that human beings can emancipate themselves from the status of nature's slavery by utilizing modern science itself. Well, this view of nature can contribute to the emancipation of human beings only if they are not a part of the nature. Because human beings are born and die in the nature, sciences would end up with eventually objectifying even human beings. While Descartes strictly distinguishes human consciousness from nature, the contemporary science investigates even the human consciousness as physical and chemical energies. The modern view of nature came about as a replacement for the teleological view of nature. The teleological view dominated the ancient and the middle ages. The modern view criticized the teleological view as anthropomorphic. But the modern view denies even the subjectivity of human beings, when it distinguishes the nature from human beings in order to avoid the error of anthropomorphism. The human beings have been degraded to the passive factors that are determined by objective conditions. In this paper, I investigate the justifiability of immanent teleology and its significance for our age. I argue that immanent teleology can provide a philosophical basis for the symbiosis of nature and human beings and for the mutual respect of human beings. This paper is composed of three parts. In the first part, the modern view of the nature and its problematic are investigated. In the second part, the teleological view of the nature, its justifiability and the traditional arguments against it are investigated. In the third part, the significance of the teleological view of nature for our technological age is investigated.

In the first step that medicine had became a study, a disease ment the pain that people suffered, in both the Oriental medicine(韓醫學) and the Western medicine. But the Oriental medicine and the Western medicine have typical opinion each other in the progress of sysytematizing the medicine. And, the reason that their cognition of the disease has been changed stems from the differences of view of the world, and the element of culture and society, which belongs to concerned scholars. The ideology and theory of ancient chineses who are considered as a constructors of the Oriental medicine's basis are formed from the attitude to adjust and accept the changes in the nature according to senses they feel. To adjust the nature, understanding of nature's rule was their priority. 'Yin-Yang and Five-phase theory(陰湯五行理論)' as systematized as a principle by recognizing nature's rule through those effects, and qi(氣) is appeared. which help everything exist as a perfect indivisual. And, they regarded continuously various changes of nature is due to the change of qi under the 'Yin-Yang and Five-phase theory'. For creature like a man is regarded as a change of qi, according to the rule of 'Yin-Yang and Five-phase theory', also the soul controling lives was regarded as temporary result revealed in the process of the change in qi's Yin-Yang and Five-phase(陰陽五行). that view of nature is established as a universal ethics to nature and human through a book, 'the Hwang-Ge-Nae-Kyung(黃帝內經)' and forms the basis theory of the Oriental medicine. Early the Western medicine differs from present one. The 'Body fluid theory(體液學說)' of early the Western medicine, represented by Hippocrates and Galen, tried to get an answer to the physiology and pathology through the growth of body fluid. In other words, it regards man's secretion or body wound or anatomy as a cause of disease and living as well. This body fluid correspond to the qi, considered as the origin of a life in the Oriental medicine, in that it is movable and unclear in each domain. The similarity between qi and body fluid, movable and changable, is the main reason that the surgery has not developed within these two theories. But, though body fluid is something visible and is changable in condition of liquid, it doesn't have such features as qi that can variously change into solid, liquid, energy, soul, and so on. So to speak, qi contains all imaginable features of objects in its conception. In contrast, body fluid is only a fluid that can control the physiological function. The Oriental medicine regards the disease as disorder of qi, also body fluid pathology says that the disease is a disorder of body fluid. Thus, both has consistent opinion about disease in the point of disorder. O.M.D(韓醫學者) thought the all disorder of mind and body, disorder between mind and body, even a change in nature were caused by the change of qi. But, because body fluid pathology couldn't explain that such organization as human, animal, and plant has a relationship with another objects. It could define a disease as a matter phenomenon like disorder of body fluid, but couldn't reach to find the consistency among the various objects in nature. Since the Oriental medicine thought of disease as breakage of Yin-Yang balance(陰陽調和) in other words abnormal function. Four great doctor in Kum and Won dinasty(金元四大家) tried to understand feature of disease, which caused a disease, and pathogenesis by explaining sa-qi(邪氣 bad effect making body function disorder) and peculiarity of patient's body rather than disease itself. Ha-Ghan(河間), who understood pathological mechanism through etiology itself, explained the process and feature of disease. In contrast Won-So(元素) and Dong-Won(東垣), who tried to understand the pecularity of disease through physiologycal mechanism tried to understand pathologycal mechanism between living energes, so to speake Wui-qi(胃氣), and 'yum-hwa(陰火)' which generates in abnormal function. The the Western medicine faced the new wave from the late of 17C, and then in paris where often the new era of clinical medicine. Solid pathology generally came to the front of fluid pathology with Bichat insistance that disease is not invalance of body fluid but chance of original shape and quality in late 18C. In solid pathology disease is not regarded as abnormally quantative and functional condition but as change of original shape and quality. This view is based on Descartes and newton's 'machanic view of the world'(機械的世界觀), which converted the way of western thinking since 17C. and the feature of this view regards disease as an object itself, and separate disease from a patient. The disease degraded over different nature which has none relative with living creature.
