Middle-aged women experience diverse psychological and physical stresses and tensions through the menopause, aging, and taking up too many social roles, which often leads to sleep disorder. But there are not many scientific researches on the issue. Therefore, the research of efficacy of singing bowl that helps relax middle-aged women who have sleep disorder is needed to improve their health. This study was conducted with Giorgi's phenomenological method with 4 middle-aged women with sleep disorder, whose Pittsburgh sleeping quality scale marked over 5 points, who took part in singing bowl experience for 40 minutes and did the interview. The study resulted in following conclusions that through participants' singing bowl experience, 518 constructive meanings, 15 meaning units, 7 sub components, and 2 group subjects were drawn up. Firstly, when participants took part in the singing bowl experience, they underwent physical, mental, imagery experiences which are physical pain and muscle relaxation, mental relaxation, and positive mindset and imaginary images and colors. Secondly, physical changes that the participants felt after singing bowl experience was increased physical relaxation, improved physical symptoms and more physical activities, and psychologically participants also felt reduced anxiety, increased happiness and positive mentality. And behavioral changes are relaxed movements, increased activities, and improved sleep is huge benefit through changes of sleep pattern. In this study, singing bowl is confirmed to be effective both physically and psychologically on relaxing the middle-aged women's tensions that are caused by sleep disorders and singing bowl experience is meaningful in that the middle-aged women as well as modern people with the sleep disorders can be helped to have better lives.

The present study aims to investigate the difference of soundscape evaluation results from on-site field test and laboratory test which are commonly used for soundscape surveys. In order to do this, both field and lab tests were carried out at four different areas in Cheongju city. On-site questionnaire surveys were undertaken to 65 people at 13 points. Laboratory listening tests were carried out to 48 adults using recorded sounds and video. Laboratory tests were undertaken to two different groups who had experience of field survey or not. Also, two different sound reproduction tools, headphones and speakers, were used in laboratory tests. As a result, it was found that there is a very close correlation between sound loudness and annoyance in both field and laboratory tests. However, it was concluded that there must be a difference in recognizing the figure sounds between field and laboratory tests since it is hard to apprehend on-site situation only using visual and aural information provided in laboratory tests. In laboratory tests, it was shown that there is a some difference in perceived most loud figure sounds in two groups using headphones and speakers. Also, it was analyzed that there is a tendency that field experienced people recognize the figure sounds using their experienced memory while non-experienced people can not perceive the figure sounds.

The introduction of dongbal[bara] is in line with Buddhism which was transmitted from India through China. Therefore, this paper tracked down the records of dongbal in Indian and Chinese Buddhism, and especially in scriptures and in ritual texts of Korean Buddhism, and studied the functionality and the use of dongbal, and the attributes of Baramu. Among the scriptures that record dongbal, 『Myobeopyeon hwagyeong(妙法蓮華經)』(A.D.406) is the earliest to be translated. The records of bara in the scriptures were written as dongbal(銅鈸) mostly, and that it was used as ritual tool(法具), instrumental offering, and religious ornament(莊嚴物). The oldest record which can verify that dongbal was used in Korea is 『Seodaesajajaeryugijang(西大寺資財流記帳)』(A.D.780). The oldest cymbals-like relic remaining today, the reliquary from the temple Gameunsa built in A.D.628, dates back to the early period of Unified Silla. This indicates that dongbal has been used at Korean temples by the 7th century at least. The records of dongbal(銅鈸) written in cheong-gyu(淸規, buddhist monastic rules) and ritual texts are classified as myeongbal(鳴鈸) and dongbal(動鈸). The letter 'myeong(鳴)' of myeongbal means to make a sound, and thus myeongbal refers to clash and make the sound of the bara. It is verified that myeongbal had certain established rules and methods. It appears that dongbal(動鈸) refers to Baramu(the cymbals dance) since the letter 'dong(動)' means movement or to move. Hence, the concept of movement was added to the signification of myeongbal, and became dongbal(動鈸), and then developed into baramu being transmitted until today. There are 8 types of Baramu transmitted in Korean Buddhist rituals, and they could be classified into purifying ritual, inviting ritual, protecting ritual, offering ritual, bathing ritual, dressing ritual, saluting ritual, and praising ritual according to their attributes.

In this study, we conducted a flora survey at Mt.Bakdal (363m) and Mt. Myeongbong (245.3m) in Paju-si, Gyeonggi-do. A total of 405 taxa, including 2 forms, 32 varieties, 8 subspecies, 363 species, 261 genera, and 87 families, were surveyed in the two mountain areas. The ferns were identified as 12 taxa from 6 families, the gymnosperms as 6 taxa from 2 families, the dicotyledonous plants as 290 taxa from 70 families, and the monocotyledonous plants as 97 taxa from 9 families. The remarkable plants included 8 taxa of the Korean endemic plants, which were Populus tomentiglandulosa, Salix koriyanagi, Clematis brachyura, Viola seoulensis, Forsythia koreana, Paulownia coreana, Weigela subsessilis, and Hemerocallis hakuunensis, and 3 taxa of the rare and endangered plants as designated by the Korea Forest Service, including Tylophora floribunda as Vulnerable (VU) species, and Viola albida and Chionanthus retusus as Least Concern (LC) species. The invasive alien plants were 35 taxa, including Rumex crispus, Phytolacca americana, Cerastium glomeratum, Chenopodium album, Chenopodium ficifolium, Lepidium virginicum, Amorpha fruticosa, Robinia pseudoacacia, and Trifolium repens, accounting for 8.5 percent of the 405 taxa of the surveyed plants. We intend to further identify plants through the studies on unsurveyed areas in the western part of the DMZ, identify the native habitats of rare and specialty plants, and use them as basic data for managing ecosystem-disturbing plants.

In der vorliegenden Arbeit geht es um das Primat des Seins und die Ereignisontologie, denen der Diskurshorizont zwischen der Ontologie der philosophischen Hermeneutik und der dichterischen $Repr{\ddot{a}}sentation$ der Seinsquelle in $H{\ddot{o}}lderlins$ spekulativem Gedicht, >Andenken<, das die spekulative Philsophie als eine Philosophie ${\ddot{u}}ber$ das Wissen um Ursein vor dem Denken darstellt, zugrunde liegt. $H{\ddot{o}}lderlins$ und Hermeneutische Ontologie nimmt erstens das Ursein, das die ontologische Voraussetzung des Denkens sei, als die nicht nur logische, sondern auch temporale Quelle auf Grund der Kritik an der reflexiven Struktur des modernen Denkens an. Zweitens suchen beide die $Gesinnungsm{\ddot{o}}glichkeit$ des Urseins, das niemals ein begreifbarer Gegenstand des Denkens war, deshalb immer schon ${\ddot{u}}ber$ das Denken ${\ddot{u}}bertrefflich$ ist, auf der ontologischen Seite aus der selbstnegierenden Bewegung des Seins, auf der erkenntnistheoretischen Seite aus dem sprachlichen Ausdruck des Seins: Insofern das reflexive Denken die analytische Unterscheidung zwn Prinzip hat, ist das Ursein deshalb der logische Ursprung des analytischen Denkens, weil das Unterschiedene aus dem Einen geteilt wird. Und das Ursein ist deshalb auch die geschichtsphilosophische Arsche, weil das Viele die geschichtliche Selbstentwicklung des Einen ist. Aus dessen Grund $l{\ddot{a}}sst$ das Sein, das allem vorausgeht, mit seiner geschichtlichen Selbsterscheinung als negativer $Selbstverkl{\ddot{a}}rung$ und darnit zugleich mit dem sprachlichen Ausdruck als der epischen Symbolisierung solcher Ereignissen sich selbst als etwas sein. Das Wort des Verstandes, das nur die Negationsbewegung der Analyse ist, kategorisch einbegrenzt ist, kann daher nicht das Verweilen bei dem Geschehen der $urspr{\ddot{u}}nglichen$ Seinsquelle sein. Das dichterische Wort, das der Stimme aus der Seinsquelle $zugeh{\ddot{o}}rig$ ist, ${\ddot{u}}bersetzt$ die Selbstbewegung des Urseins auf den hermeneutischen Sinnhorizont, in dessen Spielraum das Ursein sich selbst aussagt. $Schlie{\ss}lich$ hoffe ich damit, in dieser Arbeit davon ${\ddot{u}}berzeugend$ vorderseite zu legen, dass $H{\ddot{o}}lderlins$ Gedicht, >Andenken< nicht nur die poetische Gesinnung auf die Seinsquelle, sondern auch die hermeneutische Ontologie der Seinsquelle ist.

The purpose of this study is to illuminate the meaning of the soundscapes of two bells, Daeheung-dong Cathedral and Sungsimdang in Eunghang-dong, which are landmarks and attractions in the historic downtown of Daejeon. The study was conducted through field research and recordings, as well as literature studies of related documents and soundscape theory. Daejeon city was developed along with Daejeon Railway Station during the Japanese colonial period in the early 20th century. As the Chungnam Provincial Office moved to Daejeon, Daeheung-dong and Eunhang-dong in Jung-gu, located near Daejeon Station, developed significantly and formed the city centre. As major administrative agencies moved to Seo-gu in the 1990s, the downtown area of Daejeon was on a path of decline, and the decline accelerated with the development of Sejong city. Meanwhile, Daeheung-dong Cathedral and Sungsimdang, founded by refugees during the Korean War, firmly protected the historic downtown area of Daejeon, where the natives left. Daeheung-dong Cathedral, established during the Japanese colonial period, is a local landmark with a history of 100 years in 2019. Sungsimdang, which was created with the backdrop of the Korean War, is also a historical and cultural asset with a history of 60 years and a local landmark selected as the No. 1 tourist attraction in Daejeon. This research, which started from the sound of the bells of Daeheung-dong Cathedral, heard even in the neighboring residential areas, led to the discovery of the bells of Sungsimdang in Eunhang-dong, located across the street. In this paper, the bells of Daeheung-dong Cathedral and Eunhang-dong Sungsimdang have characteristics of soundmarks according to R. Murray Schafer's soundscape sound category. Furthermore, this paper attempted to analyze the meaning of the two bells according to the relatively recent EU soundscape definition. These two bells are signal sounds at the surface level, but are the sound marks of the historic downtown area of Daejeon at the deep level. Although there are outward differences in size, scale, frequency, and famousness, these two bells share a meaning in terms of locality and good influence with the historicity and spatiality of a special relationship. The implication of this study is that the two places should be preserved as local historical and cultural assets not only as visual landmarks but also as sound marks in the urban regeneration or urban development of Jung-gu, Daejeon.

This study researched the spawning sites of Kaloula borealis in a large number of wetlands in Jeju Island between May and August from 2007 to 2010. Based on the surveys, we discovered the locations of their habitats by investigating their calls from a rainy night to the next day and where their spawning sites were by ascertaining the existence of their eggs and tadpoles. According to the results, 83 wetlands were used as spawning sites across Jeju Island. A large number of wetlands were found to be permanent wetlands for Kaloula borealis. In addition, 81.9% of the wetlands in Jeju Island were found to be at an altitude of 150m or lower, and they spawned in shallow water not more than 50cm in depth. By region, 54 wetlands were in Jeju-island 29 wetlands were in Seogwipo-si. One of the reasons that Seogwipo-si has less wetlands than Jeju-si is that there are more orchards in Seogwipo-si than Jeju-si; accordingly, wetlands in Seogwipo-si were found to be more destroyed by farming. In the case of Seongsan-eup, a reedy marsh stretches out widely so that spawning sites were well preserved compared to other regions. This research will provide useful data for sustaining the population of Kaloula borealis by protecting their spawning sites from development, by offering habitats, and restoring spawning sites, which have become severely damaged and destroyed.

In this paper, we introduce a reading training program offering visual-auditory cue with noise cancellation function (RT program) developed by us. The RT program provides some training sentences with visual-auditory cues. Motor speech disorder patients can use the visual and/or auditory cues for reading training. To provide convenient estimation of training result, we developed a noise cancellation algorithm. The function of the algorithm is to remove noise and auditory-cues which are recorded with reading speech at the same time while patient read the sentences in PC monitor. In addition, we developed a function for finding out the first starting time of reading sound after a patient sees a sentence and begins to read the sentence. The recorded speeches are acquired from six people(three male, three female) in four noisy environments (interior noise, white noise, car interior noise, babble noise). We evaluated the timing error for starting time between original recorded speech and processed speech in condition of executing noise cancellation function and not executing. The timing error was improved as much as $4.847{\pm}2.4235[ms]$ as the effect of noise cancellation. It is expected that the developed RT program helps motor speech disorder patient in reading training and symptom evaluation.

The objective of this study was to develop clothing-type wearable motion sensing and feedback systems to enhance children's sports by promoting visual and audio feedback. In this study, several applications, such as fabric sensors, sportswear integrated with various types of fabric sensors, and fabric-based motion sensing module design, as well as a visual and audio feedback system for gaining a better understanding of a child's interest in a type of exercise, were developed. An SWCNT-based stretchable fabric sensor was developed for motion sensing, and sportswear was designed using the fabric sensor that was integrated into the limbs of the garment. The sensing module was developed, and sensory performance was evaluated through a joint motion experiment for children. In addition, using the feedback system that was developed in the form of an accessory, the responses of light and sound were also examined based on the movement of the child who was wearing the sportswear prototypes. This study focused on the development and assessment of prototype designs for children's sportswear and accessory products that can help to ascertain a child's interest in a particular exercise.
