Objectives: Oral health management is important to improve the quality of life among the elderly. This study investigated the performance of elderly oral health management among some care workers in long-term-care hospitals. Methods: The study subjects were 174 care workers in 10 long-term-care hospitals. Data on general characteristics of care workers, attitude, recognition and knowledge of elderly health, performance of elderly oral health management were collected by a self-administered questionnaire. Data were analyzed through descriptive analysis, t-test, ANOVA, correlation and multiple regression analysis by using a SPSS version 23.0 statistical program. Results: The performance score of oral health management was $4.34{\pm}0.64$ on the 5-point Likert scale. The subjects who exercised more than 2 times a month were significantly higher in their performance of elderly oral health management compared to subjects who did not exercise (${\beta}=0.232$, p=0.035). And, the subjects who cared 10-19 persons were significantly higher in performance of elderly oral health management compared to subjects who cared more than 20 elderly (${\beta}=0.246$, p=0.020). The oral health behavior of care worker (${\beta}=0.271$, p<0.001) and the knowledge of oral health care (${\beta}=0.055$, p=0.008) were positively related to the performance of elderly oral health management. Conclusions: The educational program designed to improve knowledge of care workers in accordance with the standard textbook for training care workers should be developed, and the long term education program should be reinforced to improve the performance for elderly oral health care. If care workers can care a proper number of old persons, they will give oral health care to them.

Due to global warming, crop supply methods and limited agricultural space are problematic. Vertical smart farms can be an alternative. However, it is difficult to secure air homogeneity such as air velocity, temperature, CO₂ despite paying close attention to maintaining and managing the growing environment of crops. Therefore, this study analyzes the optimal conditions and presents a formal framework so that workers can secure a homogeneous environment of crops at any location depending on the size of the module. Based on this study, crops can be produced efficiently by creating an customized growing environment for vertical smart farms.

박부용·홍소월의 가창방식 분석연구 -경기12잡가 <유산가>에 사용된 목기교를 중심으로-

최세은 ( Choi Se-eun ) 한국음악사학회 2017 한국음악사학보 Vol.58 No.-

가창방식이란 노래 부르는 것에 대한 방법과 방식 일체인데, 이는 노래부르는 사람이 목을 기교적으로 어떻게 사용하느냐에 따라 각각 다르게 나타난다. 선율의 곡조가 유사하더라도 부르는 사람마다 음악적 질감이 다른 것은 가창자의 목기교 구사 방식에서 기인한다고 할 수 있다. 즉 목기교는 그 음악적 유형을 다양하고 풍부하게 만드는 실질적 요소인 것이다. 이러한 목기교를 밝히는 것은 곧 창자가 노래 부르는 방식의 구성 원리와 나아가 그 전모를 밝히는 것과 직결된다고 할 수 있다. 그간에는 노래 부르는 방식은 개인의 개성이나 경험에 따른 것이라 간주되어 학술적으로 다루어지지 못했다. 그러나 이번 연구를 통해 목기교가 분자와 같이 작은 의미 단위들의 구성 및 결합이라는 사실을 확인하면서, 가창방식에 관한 학술적 계측·계량을 시도하게 되었다. 본고에서는 특히 그간에 조명되지 못했던 일제강점기 창자이자 당시의 스타였던 박부용·홍소월을 선정하였다. 이들이 취입한 곡목 중 경기 12잡가의 백미로 꼽히는 <유산가>를 대표로 두 창자가 구사한 목기교의 유형과 양상을 파악하였다. 우선 선행의 채보 자료를 검토하고 그것에 사용된 시각적 기호를 차용 및 재설정함으로써 객관성과 공동의 합의를 얻은 부호를 설정하고자 하였다. 그 결과 목기교의 유형은 떠는목·미는목·흘리는목·끼는목·뻐드렁목·속목·감는목·굴리는목·치는목의 9가지로 대분류되었으며, 제Ⅲ장에서 마루별로 목기교가 쓰인 지점인 사용음에 따라 그 용례를 확인하였다. 이는 다시 선율진행형·꾸밈·속도·발성·강약의 다섯 가지 요소를 고려하여 세부적으로 설명하였다. 박부용·홍소월 창의 <유산가>에서 최종적으로 많이 사용되는 목기교는 떠는목이다. 그리고 치는목, 감는목, 끼는목, 뻐드렁목, 굴리는목, 속목의 순서로 사용되었고 미는목, 흘리는목은 등장하지 않았다. 특히 떠는목, 치는목은 모든 마루에서 나타난다. 두 창자는 음악적으로 지루하지 않게 끼는목, 굴리는목, 뻐드렁목을 사용할 뿐 아니라, 음색과 음질적으로 분명하게 차이를 느끼게 하는 속목을 구사하기도 하였다. 또한 음악의 절정에 해당하는 마루에 다채로운 목기교를 구사함으로써 음악을 고조시키고 흥미로운 진행을 이끌어냈음을 확인하였다. 이를 통해 박부용·홍소월은 음악적 내용과 연관하여 목기교를 어디에서 사용할지 판단하는 능력, 즉 목기교의 구성 방식과 다양한 유형의 목기교를 구사할 수 있는 음악적 기량 등이 탁월한 창자라 할 수 있다. 이번 연구는 박부용·홍소월 <유산가>의 목기교를 분석함으로써 이들 가창의 구성 원리를 밝히고자 하였는데, 크게 세 가지 점에서 의미있다고 생각한다. 첫째, 박부용과 홍소월의 <유산가>를 최초로 학술적 자료로 채보했을 뿐아니라, 그 실제 가창을 시각적 기호로써 재현하고 학술적·합리적 방법으로 구성 원리를 이해하고자 하였다는 점에서 그러하다. 둘째, 노래 부르는 방식과 같이 창자의 개성과 임의성이 강조된 음악적 특징을 악보로 재현해낼 수 있는 방법론을 제시한다면, 앞으로 잡가 뿐 아니라 전통 성악의 연구로도 확장할 수 있을 것이다. 또한 가창에 있어 적확한 지시를 가능하게 하여 교육의 활성화에도 기여하는 바가 있을 것이다. 셋째, 목기교 분석은 다양한 유형의 가창방식이 구성되는 원리와 그것이 지닌 가치와 의미를 확인할 수 있는 하나의 방법론이 될 수 있다. 따라서 작금과는 다른 노래의 유형이자 전통사회에서 자연스럽게 형성된 옛적의 노래부르는 방법을 지금 시대에서 환기시킨다면 옛 소리의 복원이나 응용의 가능성도 열 수 있으리라 예상한다. The singing style is the method and manner about singing a song. It appears differently way depending on how the singer uses his vocal technique. That each singer`s musical feel is different although the tunes of the melody are similar is attributed to the singers` way to make use of the vocal technique. That is, the vocal technique is the substantive element which makes its musical type diverse and abundant. Revealing this vocal technique is directly connected with revealing the constitution principle of the singers` singing method and its full account. The singing method has been considered to be a thing following the personal individuality or experience and has not been dealt with academically. However, as it was confirmed through this study that the vocal technique was the constitution and combination of the small meaning units like the molecule, the academic measuring and gauging on the singing method were attempted. In this paper, Pak Pu-yong 朴芙蓉 and Hong So-wol 洪素月 were selected who were the singers and stars during the Japanese colonial era. The type and aspect of the vocal technique both singers made use of were apprehended through Yusan`ga 遊山歌 chosen as the best of Kyonggi sibi chapka 京畿十二雜歌 among the song list they recorded. First of all, the mark obtaining the objectivity and common consensus was set by borrowing and resetting the visual sign used for the precedent score data. As a result, the type of vocal technique was classified into 9 things: ttonun mok 떠는목, minun mok 미는 목, hulinun mok 흘리는목, kkinun mok 끼는목, ppodurong mok 뻐드렁목, songmok 속목, kamnun mok 감는목, kullinun mok 굴리는목 and ch`inun mok 치는목 and the example of the use note, the spot where the vocal technique was used according to each period in chapter Ⅲ. It was explained in detail in the light of 5 elements: melody progress, decoration, speed, vocalization, and dynamics. The vocal technique used much finally in Yusan`ga by Pak Pu-yong and Hong So-wol is ttonun mok followed by ch`inun mok, kamnun mok, kkinun mok, ppodurong mok kullinun mok, songmok, and minun mok and hulinun mok did not appear. Especially ttonun mok and ch`inun mok appear in all periods. Both singers not only used the kkinun mok, kullinun mok, and ppodurong mok not to be boring musically but also made use of songmok. Also it was confirmed they elevated the music and attracted the interesting progress by making use of a variety of vocal techniques in the period applicable to the peak of music. It is confirmed through it that Pak Pu-yong and Hong So-wol have the ability to judge where to use the vocal technique in association with the musical contents and have the excellent musical capability to make use of various types of vocal techniques while knowing how to constitute the vocal technique. This study was intended to reveal the constitution principle of singing by analyzing the vocal technique of Yusan`ga by Pak Pu-yong and Hong So-wol it is significant in three points. First, this study tried not only to make Yusan`ga by Pak Pu-yong and Hong So-wol into the academic material for the first time but also to reproduce the real singing into the visual sign and understand the constitution principle in an academic and rational way. Second, if it suggests the methodology that can reproduce the musical characteristic emphasizing the singer`s individuality and temporality into the score like the singing method, it will be able to be expanded to the study of the traditional voice as well as the folk song in the future. It will enable the exact directions in singing, contributing to the activation of the education. Third, the vocal technique analysis can be a methodology that can confirm the principle various types of singing methods are constituted, and the value and meaning it has. Therefore, if the way to sing an old song that is a different type of song from these days was formed naturally in the traditional society is educated in present times, it is expected the old sound will be able to be restored or applied.

수직형 스마트팜에서 균일한 품질의 작물 수확을 위해 환경 모니터링을 해야한다. 지금까지는 물리적 한계와 비용을 고려하여 일정 구역별로 부착된 센서를 통해 모니터링이 이루어지고 있다. 미관측지점에 대한 정보의 부재로 인해 작물 생장에 중요한 공기 분포를 모니터링 하는데 한계가 있다. 이에 본 연구에서는 최소한의 센서 만으로도 보다 정확한 모니터링을 위해, 공간보간법을 통해 공간에서 환경 변수의 연속적인 데이터를 추정하였다. 공간보간에 많이 사용하는 역거리가중법을 적용하여 추정했고, Python을 통해 구현하였다. 최종적으로 공간보간된 공간 전체의 공기분포는 3D 시각화를 통해 모니터링 관리자가 직관적으로 분석할 수 있는 방안을 제안하였다.

In a vertical smart farm, the amount of light is controlled by multiple artificial light, so the amount of heat generated by artificial light has a great influence on the indoor temperature. This study aims at Energy Analysis of Vertical Smart Farms based on the Insulation of the Envelope. The Cases were divided into four according to the type of wall, roof, and floor insulation of the building, and each case was divided into four temperatures. By simulating this with TRNSYS, the cooling load was calculated. In each case, the thickness increased as the insulation level decreased based on the Building energy efficiency rating(에너지절약설계기준). But regardless, as the insulation level decreased, the cooling load increased. There was a clear difference according to the insulation grade in summer than in winter. The lower the insulation grade, the greater the difference in cooling load in summer and winter. Based on this study, we propose appropriate insulation performance for smart farms with high internal heat generation.

This study aimed to propose a method for sophisticated environmental monitoring for yield increase and uniform quality production in vertical smart farms. Environmental monitoring is generally performed by mearsuring sensors, but information cannot be obtained at all points due to cost and space limitations. As a solution to this, the factor of the growth environment at the unobserved points were estimated through RBF interpolation with sensors. Seven functions were applied, and the smallest RMSE value was derived from RBF interpolation of the Linear function. 3D Visualization of the RBF interpolation result was proposed so that the manager could intuitively analyze the air distribution throughout the space.
