The noise generated by elevators in Korean apartments houses is a very concerning factor to residents and disturbs their quiet living environment. However, there are currently no regulations or laws on elevator noise, and even measurement and evaluation methods are not clear. The elevator noise measurement method is specified in [KS F ISO 16032 Measurement of sound level from building equipment]. However, this standard is quoted as it is for conformity with international standards, so it is necessary to examine whether it is applicable to elevator noise measurement in apartments in Korea. Therefore, this study was conducted to understand the current state of apartment houses elevator noise in Korea and analyze the data to identify problems with the current standard. The operating conditions suggested by the current standard were very difficult for the reproducibility of the experiment and the satisfaction of the experimental conditions. The main issue is that it was verified as not suitable for the noise measurement of apartment houses elevators in Korea. Also, in terms of verifying the validity of the measurement frequency band, understanding elevator noise characteristics and correlation analysis confirmed that the current measurement frequency band is not a frequency band that can measure and evaluate the noise of apartment houses elevators in Korea.

The 15% of amine based extractants such as Alamine 336, Alamine 308 and Aliquat 336 diluted in 65% ANYSOL-150 (A-150) and modified by 20% octanol used for present investigations. Effect of time, pH, McCabe-Thiele study as well as stripping studies was established. And two title metal ions were analyzed by inductively coupled plasma optical emission spectrometer (ICP-OES) as analytical technique.

세대 내 승강기 소음 주파수특성을 고려한 측정 시 마이크로폰 위치에 관한 연구

강민우,오양기 한국음향학회 2023 韓國音響學會誌 Vol.42 No.2

When the building becomes high, the number of households increases and they are adjacent to the elevator. So, frequency of use of elevators will increase. Elevator noise is bound to increase in the future. However, there are currently no legal standards for elevator noise or measurement and evaluation methods that can clearly measure elevator noise in Korea. Although some methods for measuring elevator noise are presented in KS F ISO 16032, this standard is not a standard established for elevator noise. It is a standard that integrates the overall measurement method of building equipment and equipment, and the position of the microphone is selected by the experimenter during measurement. Elevator noise is characterized by a low sound pressure level as the noise in the mid-low frequency band is important. However, even today, complaints from residents about elevator noise are increasing. In this study, the position of the microphone that can most sensitively pick up the elevator noise when measuring the elevator noise was studied. According to the distance from the wall and the height from the floor, a total of 9 microphone positions were measured and analyzed. As a result of the experiment, it was confirmed that the elevator noise has a very high influence in the 63 Hz band. The measured value at the center point was identified as a factor that lowered the overall elevator noise level value. 건축물이 고층화될수록 승강기와 인접한 세대 수가 증가하고 그에 따라 승강기 사용 횟수도 증가할 것이다. 그에 따라 승강기 소음은 앞으로 증가할 수밖에 없다. 하지만 현재 우리나라는 승강기 소음에 대한 법적 기준이나 승강기 소음을 명확히 측정할 수 있는 측정 및 평가 방법 또한 마련되어 있지 않다. KS F ISO 16032에 승강기 소음 측정방법이 일부 제시되어 있지만, 이 표준은 승강기 소음을 대상으로 제정된 규격이 아니다. 건축 설비 기기의 전반적인측정 방법을 통합하는 성격의 표준으로 측정 시 마이크로폰 위치를 실험자가 선정 하도록 되어있다. 승강기 소음은 중저주파수대역이 중요한 소음으로 음압레벨이 낮은 것이 특징이다. 하지만 현재까지도 승강기 소음에 대한 거주자의 불만은 증가하고 있다. 이 연구에서는 승강기 소음 측정 시 승강기 소음을 가장 민감하게 수음할 수 있는 마이크로폰의 위치에 대해 연구하였다. 벽면에서부터의 이격거리와 바닥으로부터의 높이에 따라 총 9개의 마이크로폰 위치에 대해측정 하고, 분석하였다. 실험 결과 승강기 소음은 63 Hz 대역에서 영향력이 매우 높은 소음임을 확인하였다. 중앙점에서의 측정값은 전체 승강기 소음 레벨 값을 낮추는 요인으로 확인되었다.

김장생(金長生)의 『근사록석의(近思錄釋疑)』와 서인 성리설의 심화

강민우 한림대학교 태동고전연구소 2022 泰東古典硏究 Vol.48 No.-

This study is aimed at exploring compilation process of annotation for Chin-ssu Lu (近思錄) of Kim Jang-saeng (金長生, 1548-1631) and its importance in the history of thoughts. Zhu Xi (朱熹, 1130-1200) and Lu Zuqian (呂祖謙, 1137- 1181) wrote Chin-ssu Lu for the beginners' learning. It took great part in beginner's learning with Xiaoxue (小學) that provides fundamental guideline in action. In spite of its recognized importance, Chin-ssu Lu did not receive attention from intellectuals of the time, while Xiaoxue received constant attention after emphasis on practice of Kim Jong-Jik (金宗直, 1431-1492). Chin-ssu Lu was re-examined by Yi Hwang (李滉, 1502-1571) of the 16th century. Studying Four Books and Five Classics, Yi Hwang provided a groundwork for translation of Confucian textbooks with studying Chin-ssu Lu in his later years. But he could not finish his work. Most annotations of beginner's learning based on Zhu Xi's studies (朱子學) was organized by Seoin (西人). Kim Jang-saeng compiled the annotations of Chin-ssu Lu for the first time by writing Geunsarok Seokeui (近思錄釋疑). Unlike previous annotations, Geunsarok Seokeui contained various theories of intellectuals of Joseon and these theories took greater part than theories of Chinese intellectuals based on Zhu Xi's other writings due to Joseon's cumulated former studies about the annotations. As study of Four books and Five Classics proceeded in Joseon, independent perspectives to understand Zhu Xi's studies were born. In this trend, Kim Jang-saeng compiled these studies and made a basis for study about Chin-ssu Lu. In the process, Kim Jang-saeng supplemented Yi Yi's position in the controversy over Neo-Confucianism that continued from Yi Hwang and created a foundation for maintaining the school. 본 글은 김장생(金長生)의 『근사록(近思錄)』 주석서 편찬과정과 사상사적 의의를 살펴보고자 한다. 『근사록』은 주희(朱熹)와 여조겸(呂祖謙)의 저술로 초학자들의 학습을 돕기 위한 것이 목적이라고 주희가 직접 밝힌 책이다. 따라서 실천적 내용을 주로 수록한 『소학(小學)』과 함께 초학자 교육에 중요한 역할을 하였다. 조선에서 『근사록』은 중요한 책으로 여겨지기는 하였으나 조선 전기 김종직(金宗直) 이래로 강조된 『소학』과 달리 특별히 주목받지는 못하였다. 이것은 김종직 이래로 유학자들에게 실천을 강조하는 흐름이 강하였기 때문이라 생각된다. 『근사록』이 자주 언급되었던 것은 16세기 이황(李滉)에 의해서였다. 이황은 사서삼경 연구를 심화하여 경전 번역의 기틀을 마련하였고 말년에는 『근사록』을 주로 보았지만 체계적인 저술을 하지는 못하였다. 주자학을 기반으로 한 초학자 교육의 주석서는 주로 서인에 의하여 이루어졌다. 김장생(金長生)은 『근사록석의(近思錄釋疑)』를 저술하여 최초로 『근사록』 주석서를 편찬하였다. 『근사록석의』는 앞선 주석서들과 달리 조선 학자들의 설을 대거 수록하였다. 자신이 『근사록』을 해석한 내용과 인용한 조선 학자들의 설을 합하면 그 비중이 주희를 포함한 중국의 설보다 크다. 이는 그간 진행되어온 경전 연구에 힘입은 것이었다. 조선의 사서삼경 연구가 진행됨에 따라 주자학을 자체적으로 이해하는 관점이 생겼고, 김장생은 이를 집대성하고 분석하여 『근사록』 연구의 기틀을 만들었다. 이 과정에서 김장생은 이황부터 이어진 성리논쟁에서 이이(李珥)의 입장을 보완했고 학파를 유지할 수 있는 기틀을 만들었다.

Association between the cause of cardiac arrest and cardiac arrest recognition during emergency call by dispatcher in out-of-hospital cardiac arrest (OHCA)

강민우,김태한 대한응급의학회 2020 대한응급의학회 학술대회초록집 Vol.2020 No.2

Introduction For successful DA-CPR instruction provision in EMD, recognition of cardiac arrest by medical dispatcher is crucial. This study aims to compare EMD recognition performance according to the causes of out-of-hospital cardiac arrest (OHCA) using nationwide database. Material & Method This study is an observational study based on a nationwide, population-based OHCA registry in South Korea. The data were collected from January 2014 to December 2018. All adult patients who were 18 years and older were included. The cause of arrest was categorized according to Utstein format (medical, traumatic, drug overdose, drowning, asphyxia and others) The primary outcome is the cardiac arrest recognition rate by dispatcher. The secondary outcome is successful dispatcher-assisted (DA) CPR instruction provision by dispatcher and successful DA-CPR instruction provision within 120 seconds. Multivariable logistic regression analysis was conducted to determine the association between cause of OHCA and outcome measures. Result Total 122,289 patients were included in the final analysis. Cardiac cause as reference, adjusted odds ratio for EMD recognition (95% CIs) was 0.41 (0.39-0.43) for traumatic group, 0.73 (0.66-0.80) for drug overdose group, 0.32 (0.28- 0.36) for drowning group, 1.57 (1.50-1.65) for asphyxia group, 0.74 (0.68-0.81) for others group. DA-CPR instruction provision and DA-CPR instruction within 120 secs, showed similar results. Conclusion In these studies, EMD cardiac arrest recognition through these two questions was higher in medical and Asphyxia than in traumatic, overdose, and drowning. Therefore, we should consider developing a question that fits each situation for the recognition of the cardiac arrest.

Because non-point source pollution is very closely related to hydrological characteristics, its importance is highly emphasized nowadays along with accelerating climate change. Especially for Korea, the non-point source pollution and its control are entirely depending on runoff, precipitation, drainage, land use or development, based on geographical and topographical reasons of Korea. Many studies reported the physical (e.g., apparatus- and natural-type facilities, etc.) and chemical methods (e.g., organic and inorganic coagulants, etc.) of controling non-point pollutant source pollution however, those are needed to be reconsidered along with climate change causing the unexpected patterns and amounts of precipitation and strengthen complexity of social community. The objectives of this study are to assess recent situations of non-point source pollution in Korea and its control means and to introduce possible effective ways of non-point source pollution against climate change in near future.
