  • This study analyzes upper arm as the part of suspension through the structural analyses of fatigue. Maximum displacement is shown at the knuckle joint connected with the bracket of automotive body. Among the cases of nonuniform fatigue loads, 'SAE bracket history' with the severest change of load becomes most unstable but 'Sample history' becomes most stable. Maximum life at 'Sample history' or 'SAE transmission' can be shown with 60 or 3.5 times more than 'SAE bracket history' respectively. In case of 'Sample history' with the average stress of $-4{\times}10^4$ to $4{\times}10^4$ MPa and the amplitude stress 0 to $8{\times}10^4$ MPa, the possibility of maximum damage becomes 3%. This stress state can be shown with 5 or 6 times more than the damage possibility of 'SAE Bracket history' or 'SAE transmission'. This study result is applied with the design of upper arm and it can be useful at predicting prevention and durability against its damage.

The origins and transformations to the name of Augmented Widen the Core Powder (加味普正散) as seen in the Dr. Kim Young Hoon's Medical Records (청강 진료기록을 통해 살펴본 가미보정산의 기원 및 명칭 변화)

  • This paper analyzes information on Augmented Widen the Core Powder (加味普正散) (AWCP) in the Dr. Kim Young Hoon's medical record database, Cheongang Medical Records. AWCP is a prescription that is not found in the existing medical texts, yet is referred to in Dr. Kim Young Hoon's medical record database. By examining these records, this study shows that the original prescription for AWCP was Decoction for Rectifying the Qi with Cyperus and Kudzu (香葛正氣飮) and that this prescription was deeply related to Rectify the Qi Powder Worth More Than Gold (不換金正氣散) as well as Cyperus and Kudzu Decoction (香葛飮). In addition, AWCP had several names over a long period of time, and its name changed from the Powder of Relieving Lives and Rectifying the Qi (普救正氣散) to AWCP. In particular, this study shows that the term 'gami' (加味 augmented) indicates a change in prescription name, not a change in the composition of the prescription.

  • Purpose of this study is to suggest some modules to integrate schedule and change control. The study has been performed through the process of literature review, effect comparison of being not integrated and integrated of the schedule and change control, and finally suggest new integrated modules. The results of this study are as follows: 1) Suggestion of a Predicted Change Information Control Module: This nodule can be used to assess the impact of changes in advance and to prepare counteraction. 2) Suggestion of a Change Information Control Module: This module is used to update current schedule for the realized changes. 3) Suggestion of a Revision History Maintenance Module: This module is used to record schedule and cost revision history and to analyze the overall change trend.

  • Purpose : The purpose of this paper is to analyze the characteristics of hospital architecture constructed in each periods and identify the changing process of hospital architecture in Korea since 1945. Methods : Literature review was conducted while the data of hospitals had been collected and the subject of investigation were selected. The important point of analysis is about design conception, site plan, block plan and hospital form. Results : The characteristics of hospital architecture are identified in each periods. Developed by private sector, hospitals have enlarged their beds and sizes under the competitive environments. In terms of size and external shape, vertical form has become a dominant scene of hospital forms in Korea. Among the dominance of tower-on podium, various block plans have been adopted with hospital streets. Also a few cases of horizontal disintegrated form was introduced. Implications : This paper could be the basic data to organize the history of Korean Hospital Architecture, and insufficient data should be supplemented continuously.

  • The meanings of colors vary with time and space. For the most important events in a person's life, such as wedding or funeral, people use color to symbolize their identities or roles. Traditionally, the colors of dress had indicated the wearer's age, class, or marital status in Korea. However, Korea's exposure to western cultures has affected in many dimensions of its modern history. Especially, influenced by social change, the traditional dress has undergone many modifications in forms, silhouettes, materials, and color. However, women's mourning dress has been maintained as a long lasting tradition and the use of white in mourning dress has been regarded as a norm until recently, while men have worn a regular black suit with a black tie. But, the shift from white to black in mourning dress has been observed in recent mourning practices. To examine this change of color in Korean traditional mourning dress, a historical approach utilizing multiple resources, such as interview, observations of events, documents, and archival records was applied.

  • This study inquires into the change between two method of indivisibles, which Cavalier suggested. To cope with the objection of use of indivisibles, he modified his first method of indivisibles. Through the analysis of this transition, this study reveals the feature that Cavalier changed into reflecting the density of the figures so as to avoid the paradox related to the indivisibles and this change has the aspect of incomplete lemma-incorporation method according to Lakatos' theory.

  • This study suggests new interpretation about ancient mathematician Archimedes' 'method'. For this, we examined the core issue related to the interpretation of the 'method' and identified the unclear relation between the principle of the lever and the indivisibles, both of which have consisted of the main point of arguments. And by having conducted the exploratory historical guesswork about Archimedes' careful use of indivisibles, we make a hypothesis that the role of the principle of the lever in Archimedes' 'method' should be the control of ratio of change.

  • This study is to find out the process of changes concerning the cadastral records that consist of the cadastre, the cadastral map and various registers of land in Japanese Colonial Period. The cadastre and cadastral map were the most important part of them and became the basis of cadastral records. These two registers were first made out according to the Project of Colonial Land Survey in the year 1912. As the influx of foreign Weights and Measures was greatly influenced by the foreign concession since 1876, the traditional units of the Weights and Measures had abolished finally. The extortion of sovereignty led a rapid change to the Weights and Measures in 1910. Japan compelled us to change into Japanese System of Measurement. From that time on, Lot(筆地) and Pyeong(坪) were settled down on the registers of land.
