  • Life nurturing medicine mentioned in this paper refers to medical practice based on health preservation. This practice embraces alimentotherapy, respiration practice, qi gong, lacking food method as well as preventive medicine and geriatrics based on this theory. This life nurturing practice are noticeable through korean history. There were Korea own's xianjia(仙家) yangseng practice which after the transmission of Taoistic yangseng, it has been developed to take a field in medicine. The first publication that proofs this unification of life nurturing practice and medicine is Donguibogam ("東醫寶鑑"). Life nurturing method took more proportion in medical practice as medical books emphasized on preventive medicine like Yiyangpyun("二養編"), Boyangji were published distinguishing from other field of medicine.

  • In this paper a computer aided analysis method is proposed for durability assessment in the early design stages using dynamic analysis, stress analysis and fatigue life prediction method. From dynamic analysis of a vehicle suspension system, dynamic load time histories of a suspension component are calculated. From the dynamic load time histories and the stress of the suspension component, a dynamic stress time history at the critical location is produced using the superposition principle. Using linear damage law and cycle counting method, fatigue life cycle is calculated. The predicted fatigue life cycle is verified by experimental durability tests.

  • On this condition of steel bridge member having a crack, occasionaly it is improssible to measure of stress history and to extract test specimen. Under this situation, tried to estimate remaining service life from statistical data on traffic and existing results of fatigue test without measuring of stress history and fatigue test. The main results are as following (1) Stress history of simple beam estimated from Montecallo simulation method with probabilistic model of traffic can be use to estimate remaining fatigue life instead of measuring of stress history. (2) In such a case measuring of remaining fatigue life at bridge member haying a crack, influences of RMS model and RMC model on fatigue crack growth rate are not differ without difference of applied stress range. (3) Application of cut off method may be overestimate remaining fatigue life.

  • In this paper, it is presumed that the stress time history was generated by simulation method and investigated compatibility in regard to the reappearance of stress time history. In this procedure, the identified frequency distribution of stress range of the steel railroad bridge varies with the rational values of cut off point and bar width. Thus, we show variable aspect of the equivalent stress range results from change of cut off point and bar width. In addition, we analyze the variable of RMC and RMS model due to the cut off point and bar width of the measured stress history which influencs the prediction of fatigue life in the steel railroad bridge. The simulated stress time history is carried out by the superposition method incorporating the vertical load with rotation moment obtained from the Hermition interpolation function, and compared with developing stress results from measured maxi mum stress. Through this study, we can estimate the remaining fatigue life from a safety point of view and comparative accuracy.

  • The purpose of this study was to explore the various perspectives to read micro-history of Korean housing after the period of Opening the Port for foreigners. This study were designed to adapt original theory for exploring the unique housing perspectives without using strict basic assumption which were already developed in the area of sociology, history, anthropology and philosophy. Research method applied was literature review. Each perspective might give useful insight to read the micro-history of Korean housing on the way of change after the Period of Opening the Port in Korea. Adapted perspectives to housing history were critical theory perspective, microsociological perspective, everyday life perspective(phenomenology tradition, symbolic interaction tradition, Marxist tradition), discourse perspective, exchange theory perspective, conflict theory perspective, and life course perspective. Conclusively, each perspective must be adapted multi-supportively to read the housing phenomena, because housing change derived from complex causes and factors. The fruit of this study was to ensure the adaptable viewpoint to housing were useful to read the micro-history of housing change.

  • This study emphasizes the everyday life study based on the proper study method. From the sociological literatures, everyday life's concept, it's various characteristics, two different perspectives and life-history approach are introduced. One Home Economics Paradigm Study published in 1996 is summarized to point out the importance of paradigm shift from quantitative method based on positivism to qualitative study for human everyday life study. I examined our everyday life studies as a reader and a member of screening committee and introduced four articles using different qualitative study methods.

  • Thermal history and thermal stress of alumina specimen, which occured from thermal shock process, were calculated by finite difference method. Stress intensity factor and crack growth in cyclic thermal fatigue were calculated from single thermal shock temperature history and thermal stress. Cyclic thermal life were estimated by bending strength after cyclic thermal shock under critical thermal shock temperature. Calculated stress intensity factor was compared with real experimental thermal fatigue life of specimen. Fatigue life until critical stress intensity factor and real experimental result were comparable.

  • Chuneunja(天隱子) was publication that described the life nurturing(養生) of Taoism, consisted of 8 chapters. It was comparative primary writing and contained important contents in related to the life nurturing of Taoism. It belonged to the life nurturing of Taoism that influenced by Confucianism and Buddhism. It emphasized on the practical and rational thought that mastered morality by performing gradually. It showed the concrete asceticism method like to the basic regimen training of Taoism, for example mind control(調心), flesh control(調身), breath control(調息), conduction exercise(導引), raping teeth (叩齒法) and swallowing saliva(嚥津法). Oriental traditional regimen focused on realizing balanced human character by practicing human mind and body. It may show the direction to modern person that are troubled with harmful effect of modern civilization. If we throw away superstitious and unreal part in the traditional regimen and apply regimen in one's life, we may consider that regimen contribute to human health. Therefore, we require clear understanding for the classic data inherited from predecessors.

  • The purpose of this study is to investigate the experience of recognition struggle, which is a positive interaction with Korean society, through the life history research of the researcher ' The study was conducted as a narrative - life history analysis method. Life history data were collected through in-depth interviews. As a result of the study, the lifetime of the life history research subject, as a result of the constant challenge, considered Korea as the opportunity land and voluntarily migrated to Korea. He can analyze Korea as a fierce life to gain recognition by utilizing positive adaptation strategies. In other words, through the positive interaction of recognition struggle, he negotiated with the mainstream society and established his identity through positive experiences. In addition, through group activities, we have endeavored to protect the rights of the individual as well as the whole society and to improve the image and to integrate with the mainstream society. Through this reconstruction of life history, we can understand the life situation of Chinese leaders and know about the qualities they want to receive in Korean society. Therefore, it is suggested that this reconstruction of life history implies social welfare practice.
