  • Background: There is a need for index research on music therapy activities for the elderly in Korea. Purposes: This study aims to suggest application standards in music therapy by surveying the elderly's preference for music therapy activities. Methods: A survey of music-related actions and musical instrument preferences was conducted with 91 older people in 4 nursing homes. The questionnaire consisted of information about music activities, genres of songs, types of instruments, methods of movement, and purpose of participation in activities. Results: The preference for musical activities was for playing musical instruments, followed by singing, music appreciation, flowing movements, and concert-oriented activities. Music genres appeared in the order of popular songs, folk songs, and children's songs. The instrument type preferred drums, followed by shakers and woodblocks. As a movement application method, movement using themes is preferred. Participating in music activities was leisure, followed by stress relief and emotional cultivation. Conclusion: When applying music therapy to the elderly, it predicted that the treatment effect would be high when the elderly focus on playing musical instruments and singing activities preferred by the elderly. Music genres selected from popular music and folk songs, and musical instruments are drums and shakers. Therefore, if you use it, you can expect a more significant effect.

  • This thesis investigates the development of optical instruments in the 19th century, before the birth of the cinema, and the principle of the perception of moving images. For this purpose it traces the development stages of the optical instruments which demonstrated 'illusion of movement' from 1820s when the 'persistence of vision' had begun to be researched by scientists. Then, it examines the theory of the 'persistence of vision' or 'afterimage effect' known as the principle in the perception of illusion of movement produced from moving images. The optical instruments in the 19th century that presented the illusion of movement began with the Thaumatrope (double-sided picture disc), and appeared from the Phenakistiscope/Stroboscope (revolving disc), the Zoetrope (revolving drum) and the Praxinoscope (mirror-reflexive revolving drum), and in 1892 the Projection-Praxinoscope presented firstly the moving pictures (animation) on the screen. According to the research of psychology and physiology in the early 20th century it has been recognized that the 'afterimage effect' theory is not sufficient to explain the perception of illusion of movement from the moving images which is closely related to the particularity of the visual perception system of the human eyes. Since then, the Phi-phenomenon suggested 1912 by the Gestalt psychologist, Max Wertheimer (1880-1943), is regarded as the most persuasive theory until now, although it is still imperfect.

  • I have researched in the field the religious and performance culture of Indonesia through the musical iconography of Borobudur. There are many kinds of musical instruments which belong to India or Indonesia, performers being either court or folk musicians. Contemporary south-east Asian Indonesia has a broad religious heritage. Most of the population is Muslim, but the culture and customs are rooted in Indian Ramayana. I discovered, for example, the same percussion instruments played on a person's knees. I also came across similar string instruments with long and elliptical resonance casks on the iconography of the Incense Burner and Byam temple stone pagoda of Beakje dynasty in Korea and in Borobudur in Indonesia. The two musical instruments can not be found in other countries, such as Silla, Koguryŏ, China or the silk road area, but only Indonesia or India. This suggests that Beakje Buddhism is from the southern regions rather than China. I also discovered the same dancing motion with the court performers on the iconography of Borobudur, and the same musical instrument and performance in the Gamelan in today's Indonesian performance. Despite a disjuncture between the people and their past, the Shailendra Buddhism is alive in people's life and culture in the present day. So we can discover some familiarities between Indonesia's Gamelan and the percussional performance in Korean Buddhist rituals.

  • The inter-comparison project for seawater salinity measurements, in which 25 laboratories from 16 countries took part, was conducted by JCOMM (Joint WMO/IOC Technical Commission for Oceanography and Marine Meteorology) for the first time in 2014. Two seawater samples of different salinity values ranging from 30-35 and 20-25 for Sample A and Sample B respectively and which had sufficient homogeneity and stability were distributed to all participants. Participants measured the salinity in their own laboratories at least 3 times and reported the results. Statistical treatments were applied to the results to assess discrepancies among laboratories. 20 out of the 25 laboratories used laboratory salinometers and statistics for this group were denoted as belonging to group ${\alpha}$; while 5 out of the 25 laboratories used hand-held measuring instruments and statistics for this group were denoted as belonging to group ${\beta}$. Bias described as discrepancy among laboratories in group ${\alpha}$ was within ${\pm}0.001$ and expanded uncertainty (k = 2) was in the vicinity of 0.002. The bias and the uncertainty of Korea Institute of Ocean Science and Technology (KIOST), in group ${\alpha}$, were 0.000 and 0.002, respectively. The biases of group ${\beta}$ were greater than group ${\alpha}$ because of constraints related to instrument accuracy. Biases from 3 laboratories in group ${\beta}$ exceed the accuracy specification of the corresponding instruments. Considering that the uncertainty of Standard Seawater (SSW) is of the order 0.001 to 0.002, the inter-comparison results show that 16 laboratories among the 25 laboratories made high quality measurements, largely indistinguishable from one another.

  • The analytical performance of four commercially-available pneumatic nebulizers(Meinhard, Cross-flow, Babington, ESI PFA) was evaluated using inductively coupled plasma-atomic emission spectrometry (ICP-AES) and ICP-mass spectrometry (ICP-MS) instruments. The performance of an inert concentric nebulizer and a modified conespray nebulizer, made in Korea Research Institute of Standards and Science (KRISS), is compared with that of the four commercial nebulizers. Variation of sample introduction efficiency was investigated as carrier argon pressure and sample uptake rate were changed. Variation of sensitivity, signal stability, blank intensity and oxide/hydride ratios were also studied when the nebulizers were connected to the ICP-MS and ICP-AES instruments. It was found that good analytical result such as high sensitivity, low blank, stable signal and so on can be obtained with judicious selection of the nebulizer depending on the type of sample, sample amount, type of analytical instrument and analyte.

  • VPH (Volume Phase Hologram) grating is one of the transmission gratings and is known as its remarkable efficiency (>90%). It has two different densities of gelatins causing interference patterns. The VPH grating is favored in many astronomical instruments these days and also IGRINS, which is up coming near infrared high-resolution spectroscope expected to see the first light next year, uses the VPH grating as its cross-disperser. The infrared astronomical instruments operate at cryogenic temperature (~100K) in order to cut down thermal noise and the optical components of IGIRNS will be operated at 130K. The VPH grating is sandwiched in between fused silica or glass and glued together using optical adhesive. IGRINS is expected to go through 50 times of thermal cycling in 10 years including the performance test and this research is to check whether the physical characteristic such as the adhesion or dichromatic gelatin does not break and change from the several cryogenic thermal cycling. The two identical test gratings provided from Kaiser Optical System, Inc. are used in this test. One VPH grating is cooled down to 100K for 2 hours with maximum dT/dt = 5 and warmed up to the room temperature and another grating is kept stored in the room temperature and used as a control sample. In order to check the change, we inspected the grating with eyes and checked its efficiency and transmission at the room temperature every 10 cycling. From the 40 times of cryogenic temperature cool down cycling, the VPH grating showed no signs of change within the error compared to the control sample. We concluded the VPH grating is durable through several cryogenic thermal cycling.

  • In this study, we investigated the perception of elementary school students on inquiry activities and collaborative problem-solving ability in data-based scientific inquiry. For this purpose, 20 data-based scientific inquiry classes were conducted in 26 elementary school students in Gyeongnam City. After selecting the inquiry problem, students conducted an inquiry process to collect data using digital inquiry instruments. The following results were obtained through questionnaires and interviews after the classes: First, students perceived the step on 'inquiry design and execution' as the most useful in the data-based scientific inquiry. Second, students perceived that their scientific ability and cooperation improved through data-based scientific inquiry, with the selection of inquiry problems being the most difficult. Third, students perceived positively the improvement of cooperative problem-solving ability. From the above results, it was found that data-based scientific inquiry is necessary to improve the elementary school students' scientific inquiry ability and cooperative problem-solving ability. Based on this research, we hope that the development and research of various inquiry activities will provide opportunities for inquiry that can cultivate various abilities needed for students living in the future.
