  • The film thickness and shape of elastohydrodynamic lubrication is measured by optical interferometer, which is the most precise method for EHL film measurement. However, the interpretation of the image pattern from optical viscometer is not simple for two-dimensional shape. A newly developed method of image processing makes it possible to evaluate the film thickness and shape in every point of contact region with two dimensional aspects. In this study, we captured the film shape of EHL film by the monochromatic incident light and analyzed the film thickness with the image processing method, which uses phase shift method. From the values of intensity in fringes, the qualitative feature of film thickness in the contact area are obtained by using Zernike polynomial

  • The purpose of this study was to examine the trends of qualitative research in four representative journals in Korean LIS from 1970 to 2016. 73 papers(1.4%) were analyzed focusing on publication year, subject areas, research purposes, authors, qualitative methods, research participants, data collection methods, data analysis methods, and methods of validation. The findings are as follows: 1) Information behaviour(39.7%) was the most researched topics, followed by librarians work(20.5%), and bibliotherapy & reading education(13.6%). 2) The most frequently used research purpose was for understanding experiences(60.2%) and for improving current state(30.1%). 3) 'Grounded theory'(13.6%) and 'phenomenology'(10.9%), 'case study'(10.9%), were used frequently, while 'non-specified qualitative method' was 26.0% and 'not indicated' was 21.9%. 4) Librarians (41.0%) were the most researched participants, followed by professionals(13.6%). To collect qualitative data, in-depth interview(20.5%), interview(13.6%), and in-depth interview & internal documents(9.5%) were frequently used. There are 'loose qualitative research' group and 'scientific qualitative research' group. LIS researchers using qualitative research methods should consistently make efforts to increase qualitative theory and the philosophical assumptions, and to apply rigorous research method (data collection, analysis and interpretation, sampling, data saturation, validity and reliability). Institutionally, It is to provide 'qualitative research methods' course and to develop guidelines and standards for LIS qualitative research authors and reviewers.

  • We propose an efficient scheme for camera motion characterization in MPEG-compressed video. The proposed scheme detects six types of basic camera motions through threshold-based qualitative interpretation, in which fixed thresholds are applied to motion model parameters estimated from MPEG motion vectors (MVs). The efficiency and robustness of the scheme are validated by the experiment with real compressed video sequences.

  • As a measure of the center of data, arithmetical mean, median, mode, harmonic mean and geometric mean are generally used. Students must learn qualitative aspect of average values as well as its calculation for its adequate use. As the result of the learning, they should be able to select the appropriate average value according to the characteristic of data and problem context. For this object, the historical origin and visual interpretation of average values were introduced in this paper. And to help teaching several meanings of average values, several examples including context were suggested.

  • This study examines the experience structure and success theme in the business experience of successful young entrepreneurs in the fashion field. The study was conducted as a qualitative case study. The participants were three CEOs with more than 10 years fashion businesses experience with small and medium enterprises. Data were collected from July 2016 to June 2017 through in-depth interviews in Seoul and Gwangju as well as literature collected from other journals, newspaper articles, and books. Collected data were first summarized in 284 meaning units and then reduced to 53 common meanings through description, analysis, and interpretation processes that produced 16 sub-themes. Finally, six successful themes were extracted. The study results are as follows. First, the experience structure for successful entrepreneurs is formed by the qualitative difference of experience according to time order. Second, there are six successful themes found in the fashion start-up process. 1. Developing talent as entrepreneurs with a sense of fashion and enthusiasm 2. Passing on trial and error as a chance to communicate with customers 3. Challenge the fashion retail market with global online start-up opportunities 4. Building a system that responds to market environment changes 5. Leading and distinguishing with expertise from entrepreneurs 6. Evolve into the coexistence of members.

  • The purpose of this study is to analyse the eighth grade students' performance of open investigations for two kinds of tasks: the qualitative one which involves the descriptive approach through observation, and the quantitative one which involves the quantitative data processing through control of variables. Researcher's observation, interview data as well as students' investigation reports, self-evaluations were analysed. The difficulties of qualitative open investigation lie in detecting and dealing with unexpected observations, of which the acceptance and interpretation were influenced by preconceptions. On the other hand, managing several variables, making reliable and valid measures, and quantitative data processing constituted main difficulties of quantitative open investigation. Some students could recognize the deficiencies of their methods and findings in qualitative one, but few in quantitative one. These results suggest the teaching point for each task of open investigations.

  • The purpose of this study is to investigate the science gifted students' level of interpreting the oceanic graph and of understanding the oceanic physical concept through analyzing the Temperature-Salinity (T-S) diagram and inferring the SOFAR (SOund Fixing And Ranging) channel. A total of 106 gifted students in the 3rd year of a science gifted high school, using T-S diagrams published in one of the journals of Oceanology, developed descriptive questions asking the depth of the SOFAR channel to conduct the quantitative and qualitative analysis of graph interpretation ability. As a result, there was a big difference in the level of graphs interpretation and concepts understanding for each science gifted students such as interpreting, modeling, and converting, and exposed their alternative concepts about water temperature, salinity, and density. The results of this study will be used to understand the levels of science gifted students' graph interpretation in oceanology, and to provide the basic data for improving the teaching and learning methods of oceanology and also provide basic data for teaching material development related to graph analysis.

  • This paper presents Reflectance Transformation Imaging (RTI) as a tool to support the study of paintings and authentication. Manufacturing techniques of the artist are reviewed through the comparison between liberal perspectives and digital imaging techniques. In this study, RTI was applied to focus on the detailed textural information of eight paintings by Korean artist Lee Ji-ho. The RTI result visualizes shallow reliefs of brush strokes and different mediums on the surface technically enhanced through imaging filters, and these morphological textures on the surface act as a key factor in understanding the characteristics of the artist. The surface morphology and art criticism work as qualitative indicators to analyze the change of artistic techniques through time, and the usage of different mediums. The results of this study confirm that the RTI technique can be used as an analysis device in the study of paintings.

  • Through this study, I explored a creation of the postmodern furniture aesthetics through the transformation by student's interpretation in experiencing the art/craft/handmade/studio furniture aesthetics in postmodernism theoretically for 'wood culture experience class' or 'wood love experience class' by the Korea Forest Service because the class tends to focus on making simple wood works involved just in the practical part. Qualitative conceptual analysis as the principal methodology was used to achieve the theoretical context in the experience programs. Following the lesson one on defining the postmodern aesthetics in New Design furniture as metaphor and the lesson two on interpreting an aesthetics of art and everyday life with the wood furniture which expresses the metaphorical and symbolical aesthetics appeared as New Design furniture in postmodernism in the previous papers, I developed lesson three on creating an object using eco-friendly materials like wood in transforming an aesthetics of postmodern furniture as the final stage of the study. Therefore, the students will be able to create a piece of eco-friendly wood furniture for our environment as metaphor transformed by his/her perspective regarding a piece of selected New Design furniture.
