  • This paper deals with an experimental technique for monitoring machining conditions by analyzing cutting-force vibration measured at a milling machine. This technique is based on the relationship of the cutting-force vibrations with the feed rate and cutting depth as reported earlier. The measurement system consists of dynamic force transducers and a signal amplifier. The analysis system includes an oscilloscope and a computer with a LabVIEW program. Experiments were carried out at various feed rates and cutting depths, while the rotating speed was kept constant. The magnitude of the cutting force vibration component corresponding to the number of cutting edges multiplied by the frequency of rotation was linearly correlated with the machining conditions. When one condition of machining is known, another condition can be identified by analyzing the cutting-force vibration.

  • Objective: The aim of this study is to present a solution to problems in the services provided by the general hospitals by creating a user-centric environment through analyzing the User Journey Map and the User Context. Background: The rapid growth in aging population and the monopolization of superior medical staffs by the general hospitals increased demand for the general hospitals in Korea. But, often services provided by the general hospitals are provider-centric and low quality. Method: This study examines problems in the services provided by the general hospitals by analyzing the User Journey Map through stakeholder interviews(contextual interviews) and on-site observation. Based on the contextual analysis of the user(i.e. the patient), this study proposes new and improved user-centric services to be provided by the general hospitals. Results: Ten new user-centric services proposed by this study are: (1) "Booklet on Success Story", (2) "FAQs by Doctor", (3) "Designated Nurse", (4) "Patient Interview Record Card", (5) "Close relationship between doctor & patient", (6) "Thank You Notice Board", (7) "Step by Step", (8) "Green Cap", (9) "Patient Kit", (10) "RFID Direction Display System". Conclusion: The service design for the general hospitals proposed by this study is an important case-study on improving the environment of the general hospitals from provider(medical staffs)-centric to user(patents and its family)-centric. Application: This study is expected to be used in various areas to improve existing system(products and/or services) to be more user-centric.

  • Recently, significant tries appeared in the spatial design field were appreciated as tries to find crossing between space formation and discourse. This study is to find spatial clues from Gilles Deleuze, the modern philosopher's literature where he developed his discourse analyzing paintings of Francis Bacon, and reveal common characteristics with the contemporary spatial design. According to the analysis of Deleuze, Bacon's paintings are separated into frame-aplat, shape-figure, and contour-track. From these three elements, I extracted spatially analyzing languages of 'occurrence of shape-accident', 'space of track-sense', and 'interaction of aplat-background.' Then with these analyzing languages, I analyzed latest works of Rem Koolhaas. Deleuze Space Theory confirmed in works of Rem Koolhaas is the application of accident-focused occurred between the user and space, the space that induces accident, and differentiation between the user and space or space and site. As a result, I could confirm the common characteristic that both modern discourse and spatial design are understood as 'difference' from life and movement.

  • Characteristics of chemistry education during the enlightenment period in Korea are examined by analyzing chemistry textbooks used in the period. Specifically, the analysis is made from the aspects of science, students and teachers. As a result it is found that; first, scientific knowledge itself is emphasized, contrary to those described in the curriculum of chemistry used in the period, and it consists of introduction, non-metals, metals and organic chemistry in chemistry textbook, second, the level of chemistry is similar with that in present high schools, and its technical constitution might have been difficult for a student to study with an experiment, third, terminology lacks consistency and some textbooks include contents of other subject. It is therefore believed that the chemistry textbooks of the enlightenment period is scientifically incomplete and would not have been easy for the teachers to use them to teach the students. In addition, considering the students as a beginner of modern sciences, study level could have been too difficult for them to follow. In conclusion, it appears that chemistry education during the enlightenment period in Korea was not so successful.
