최근 사물인터넷 기술은 4차 산업혁명을 이끌 차세대 성장기술로 많은 분야에서 기술도입과 융합을 시도하고 있다. 장난감 시장 역시 사물인터넷 기술 도입으로 많은 변화가 일어나고 있다. 특히, 단순한 조작 위주의 장난감을 스마트 기기, 센서 등과 연동하여 원격제어를 하고, 부가 정보를 축적하여 활용함으로써 사장되었던 많은 장난감들이 새로운 놀이도구로 재생산되고 있다. 본 논문에서는 대표적인 놀이기구였던 팽이를 새롭게 사물인터넷 기반 스마트 팽이로 제작하기 위한 방안을 제시한다. 스마트 팽이는 초소형 아두이노 보드를 장착하고 스마트폰과 통신이 가능하도록 하여 회전 및 충돌 정보를 스마트폰으로 전송하도록 한다. 또한, 스마트 팽이에 솔레노이드를 이용한 점핑 모듈을 추가하고 스마트폰에서 점프 명령을 내릴 수 있도록 함으로써 게임 참여자의 직접 제어가 가능한 스마트 팽이 대전 게임을 구현할 수 있도록 한다.

This paper examines the unique features of Korean farmer's music-or nongak-in Hawaii by exploring three nongak groups from different decades beginning in the 1970s. The first community-based nongak group began in the 1970s, with the establishment of the Wahiawa Korean Seniors Club. In the 1980s, there was another group supported by the Kalihi-Palama Immigrant Service Center. And in the 1990s, the Hawaii Korean Farmer's Music Assoiation, which is still active, was founded. I ullustrate the overall changes made by the three nongak groups as follows. First, they show a shift from social groups playing music to a music group doing social activities. Second, from a group of people negotiating their music, through a group led by musical leadership, to a group with a leader who created his own musical leadership. Third, from a music group began out of a pseudo-shaman ritual, through a group purely playing music, to a group adding samulnori and further creating a new rhythmic pattern. These changes occurred because, while the members are all first-generation immigrants, their experience of nongak in the motherland was different because of their age differences. In addition, they emerged because the level of awareness and acceptance of samulnori-which has gained huge popularity in Korea-were different.

Samul nori/Pungmul-gut is the symbol of ethnic identity for the Koreans abroad. It is the representative diaspora musical genre which is performed many cultural events held by Koreans. It is, at the same time, a global music which is appreciated by not only the Koreans but also the foreigners. Many musical communities in various countries exhibit the cultural migration through the discourse of 'tradition/variation' and 'authenticity/hybridity' in the course of the acculturation and enculturation of samul nori/pungmul-gut. The pungmul-pae 'Bichoe June' active in Toronto, Canada was organized by a foreign performer. For the foreigners pungmul-gut is easy to access as a genre of world music. As a percussion ensemble, it is easy to learn for the foreigners. The pungmul-pae 'Bichoe June' is a 'music community' consist of the Koreans and foreigners. The band tries to preserve the traditionality and authenticity of the Korean music. There is no variation or hybridity in its music since the member still learns the authentic music through various available textbooks and internet sites. Through the participation of the Koreans and foreigners, the band stimulates the globalzation of the pungmul-gut. The enculturation of the pungmul-gut is exhibited in two performances held by the band. One was host by the Canadian progressive group and the other was by the Korean conservative community. The former understood the nature of pungmul-gut as the music of the common people. The latter, however, accepted the music as the representative traditional music but was not easy to enjoy the 'noisy' music. In other words, the positive/negative acceptance of the pungmul-gut depends of the ideological nature of the listeners rather than the ethnical nature.

한국의 전통국악기 가운데 대중들에게 가장 친근한 악기 가운데 사물놀이 악기이다. 징, 장구, 꽹과리, 북, 이 사물 악기 가운데도 특히 징악기는 소리가 웅장하고 부드러우며 감싸주는 멋이 있다. 징의 구조는 직경 $39\~40cm$인 둥근 원판과 림(Rim:전두리)으로 되어 있다. 재질은 동과 주석을 78:22의 비율로 합금한 유기(놋쇠) 제품으로 만들 때는 방짜유기로 만든다. 본 논문에서는 우선 파동방정식에 의해서 수리적으로 징의 기본 주파수를 구하고, 만곡 면으로 된 원판을 지지하고 있는 징의 Rim 두께와 깊이에 따라 징악기 소리의 세기를 나타내는 진폭과 소리 여운의 지속 시간을 변동 시키는 관계를 본 연구 논문에서 밝히고자 한다.

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.

Along with the development of information and communication technology, smart education that can learn without restrictions of time, place and equipment is activated even in the field of education. Although smart education is provided with content-based training solutions, construction of a system that grasps individual characteristics of learners and provides personalized learning is relatively weak. The activity of free choice is an important play activity of early childhood education, but it is not implemented efficiently by relying on the clinical observation of the teacher. If the IoT(Internet of Things) technology based on Hyper-Connected is applied to free-choice activities, it is possible to provide the child's personalized activity type and play-form analysis based on objective and stylized data. In this paper, we design and implement a system to monitor the child's activity of free choice by building an IoT environment that is based on open source hardware. The proposed system provides children's activity information as objective data and will be used as teacher's work mitigation and custom training material for each child.

Jing(gong) is one of the most well known Korean traditional Samulnori instruments to the general public. Samulnori is consisted of four instruments, them being : the jingo the janggu (hour-glass drum). the kkwaenggwari, and the buk(drum). Of the four instruments, the jing with its deep, and yet soft and beautiful long lingering sound embraces the sounds of the other three. The jing is a brassware instrument, a compound of $70{\%}\;copper\;and\;22{\%}\;tin.$\;A high quality brassware is used when the jing is made. The jing is shaped with a 39-40cm circular plate and a rim that gives 7.0-7.5cm of depth to the instrument. Even with its most simple structure, when the circular plate is hit during performance, the rim which supports the circular plate gives resonance to the sound making low-frequency sounds. Therefore the range of the representative frequency of the full rim jing is between $118.4{\~}366.0[Hz],$\;the lingering sound lasts for more than 20 seconds afterwards. When the jing with half of its rim cut off is hit the basic frequency is $139.9{\~}387.5[Hz].$\;And the sound lasted for ten more seconds. The jing of its rimless frequencies are distributed between $990.5{\~}1,372[Hz].$\;And the lingering sound lasts for 5seconds afterwards. Therefore, different thickness and depth of the rim may give new resonance frequencies and alter the longing time of the sound. This thesis paper will try to reveal the relationship between the thickness or depth of the rim (which holds the bending circular plate) and the frequency or the lasting time of the sound.

Purpose of Study: The purpose of this study was to analyze children's play patterns in gardening. Through this, we aimed to have significance as basic research to find ways to support children's play in gardening. Research Contents and Methods: From August to October 2022, a total of 15 participant observations and interviews were conducted with 13 children (9 4-year-olds, 4 5-year-olds) aged 4-5 years at J Daycare Center in Gyeonggi-do. The collected data was transcribed, categorized, and analyzed. Conclusions and suggestions: Children's play patterns in gardening were 'sympathetic play', 'intuitive play', and 'imaginative play'. In the garden, where nature can be easily accessed, children shared emotional interactions and feelings with nature through peer relationships. Children encountered nature in the garden and experienced intuitive, sensory play. Children made up plants, animals, and objects related to the garden and showed their imagination. Children's playfulness was revealed in gardening, and sensitivity and curiosity about changes in nature were revealed through continuous interest in nature through understanding of the mutually beneficial relationship with nature. Gardening should be approached as a long-term, continuous experience rather than a hands-on or one-time experience.
