  • 우리의 고유 음악인 향악은 그 조율체계는 물론, 기본음이라 할 수 있는 황종음의 음고도 정확히 밝혀지지 않은 상태이다. 이에 대금, 피리, 단소 등의 관악기를 중심으로 한 독주 향악곡의 황종 음고를 측정하였다. 측정 결과 황종 음고는 대략적으로 328Hz인 것으로 나타났는데, 이는 E$^b_3$(311Hz)라고 알려져 있는 일반적인 이론과는 달리 E$_3$(330Hz)에 가까운 값이다.

  • Adequate access cavity is the key to achieving endodontic success. The aims of the access cavity can be considered as follows: 1) Creation of a smooth unimpeded pathway for instruments to canal orifices 2) Removal of the entire roof of the pulp chamber in order to inspect the pulp floor, 3) Preservation of natural tooth substance consistent with the above. Recently, contracted endodontic cavities based on minimally invasive endodontics has introduced. This has the benefit of preserving the pericervical dentin more than traditional access cavity with achieving long-term success. However, some studies reported controversial results regarding root canal detection, instrumentation efficacy (noninstrumented canal area, hard tissue debris accumulation, canal transportation, and centering ratio) as well as fracture resistance. Therefore, further studies are required for accepting contracted access cavity, and modified form of traditional and contracted access cavity could be considered.

  • Objective: This study aimed to construct an overview of health-related quality of life (HRQOL) scales for application in studies of traditional Korean medicine (TKM). Methods: We analyzed all HRQOL scales from the PROQOLID web site (www.proqolid.org) regarding to classification, application purposes, and translation to Korean version. We also searched clinical studies focused on "Quality of Life" using TKM. Results: A total of 660 HRQOL instruments were analyzed; 99 were for general condition while 559 were disease-specific. Twenty clinical studies for TKM were conduced using HRQOL scales. Conclusion: The adaptation of the international HRQOL instrument is strongly recommended in TKM-associated clinical study, and development of a TKM-specific HRQOL scale is needed for globalization of TKM.

  • A model for teaching traditional Korean rhythmic patterns using Orff's ear training approach was developed and implemented with aim that it could be used as basic data for the operation of Korean music education. Children's rhythmic sense improved through teaching of sound searching, body rhythm, playing instruments, and improvising. Teaching the order of connective rhythmic patterns and a basic patterns-centered approach was more effective than teaching modified rhythmic patterns. With ear training, children perceived the stress of rhythmic patterns in advance and they perceived the length of sound. These results show that this model can be used as a basic approach in the operation of Korean music education.

  • The purpose of this study is to analyze the effects of the use of calculators in elementary school mathematics education. For this purpose, we established the subject matters of the research as folloows; (1) to develop the lesson plan and the students' activity sheet related to the use of calculators. (2) to analyze the effects of the use of calculators when we applied the materials developed. Four classes of sixth grade students were sampled two elementary schools in D city. Two of them were assigned to the calculator group and the others to traditional group. The experiment was conducted for 10 class times. Two kinds of test instruments were used: pretest and post test. The pretest scores guaranteed that both groups were homogeneous. Post-test was used to identify the effect of use of calculator and the post-test scores were analyzed by t-test. We also used questionnaire to identify the students' change of attitude toward mathematics. The results of this study as fellows: (1) The calculator group got scores significantly higher than the traditional group on the test. (2) The students' attitude in calculator group was changed a little positively.

  • Unconventional computer vision and image processing techniques offer significant advantages for experimental applications to shaking table testing, as they allow the overcoming of most typical problems of traditional sensors, such as encumbrance, limitations in the number of devices, range restrictions and risk of damage of the instruments in case of specimen failure. In this study, a 3D motion optical system was applied to analyze shake table tests carried out, up to failure, on a natural-scale masonry structure retrofitted with steel reinforced grout (SRG). The system makes use of wireless passive spherical retro-reflecting markers positioned on several points of the specimen, whose spatial displacements are recorded by near-infrared digital cameras. Analyses in the time domain allowed the monitoring of the deformations of the wall and of crack development through a displacement data processing (DDP) procedure implemented ad hoc. Fundamental frequencies and modal shapes were calculated in the frequency domain through an integrated methodology of experimental/operational modal analysis (EMA/OMA) techniques with 3D finite element analysis (FEA). Meaningful information on the structural response (e.g., displacements, damage development, and dynamic properties) were obtained, profitably integrating the results from conventional measurements. Furthermore, the comparison between 3D motion system and traditional instruments (i.e., displacement transducers and accelerometers) permitted a mutual validation of both experimental data and measurement methods.

  • This study will attempt to show how marriage ceremonies in Korea have reflected marriage custom influences from science and industrialization the study focuses on changes in traditional features. As a result of science and industrialization, the social patterns of Korean marriages have considerably changed, due to the impact of western values. There are three stages of the Korean marriage ceremony: before the ceremony (Sun-rye), the ceremony (Bon-rye) and after the ceremony (Hu-rye). The research examined how these marriage customs were influenced by science and industrialization. The instruments were 750 questionnaires, analyzed through data processing and personal interviews with 25 married women. The data were analyzed by making use of the SPSS program using frequency analysis and $x^2$-test. The results suggested that, since 1960, Korean marriage ceremonies mainly conformed to the marriage customs of traditional society. Since 1970, traditional customs of the before the ceremony (Sun-rye) process have been, in large part, eliminated. The ceremony (Bon-rye) process has been changed to western style, and the after the ceremony (Hu-rye) process has been altered to some degree.

  • For more than 100 years, American skyscrapers got along with the change of Modern architecture. However, high-rise building can not be regarded anymore as a monopoly of America. The purpose of this study is to clarify the aesthetic characteristics of Asian high-rise buildings. Basic concepts on the aesthetic and artistic expression of high-rise building have been discussed, emphasizing the importance of artistic characteristic. A brief introduction on the rise of Asian high-rise buildings also summarized in terms of changing trends for decades from 1970s. Among the 75 buildings in Asian countries out of 100 tallest buildings in the world, 10 buildings are selected to clarify the artistic characteristics which can be presented as an Asian trend in 21st century. The results can be summarized as follows; It was from 1990s that the Asian high-rise buildings began to express a specific regional aesthetics as a trend of post-modernism. Conventional ideas, traditional objects, and regional shapes and patterns are good instruments to successfully represent their national prides. Religions in Chinese and Islamic culture are popular motifs in Asian countries as well as feng shui and conventional idea of five primary elements. Traditional objects like pagoda and minaret are good precedents that can provide friendly recognized vertical objects. Many other interesting cases can be found referring to the traditional shapes and patterns like Chinese character, geometric pattern, Islamic sign, etc.
