Normally, multiple socket-outlet is manufactured with soldered, welded permanent connection (termination). Because this procedure is very non-environmental and requires many labor forces, many companies skip this process. To solve this these problems, this research had to design permanent joint type multiple socket-outlet, develop safer multiple socket-outlet than is sold in markets. Progressing this research, we took 3 steps. First, we had to design device for fixing a frame suitable for multiple socket-outlet. Second, this multiple socket-outlet must pass fundamental standards through international standard (IEC 60884-1) and Korean standard (K 60884-1) tests. Third, it had to pass both several mechanical and electrical tests which is more strict than fundamental standards and vibration and impact tests following KS standards for enhancing its safety. After finishing 3 steps, we could obtain objective and fair data, develop environmental permanent joint type multiple socket-outlet without soldering crimped connection.

역사문헌기록 속의 난방관련 단어에 관한 연구

조원석 ( Cho Won Seok ),문정인 ( Moon Jung In ) 한국기초조형학회 2019 기초조형학연구 Vol.20 No.1

우리나라 전통주택의 발달과정과 당시의 생활상을 조금 더 명확히 규명하기 위해 고고학적 연구결과와 문헌학적 연구결과를 상호보완적으로 활용하여 설명할 필요가 있다. 따라서 본고는 한국고전종합DB와 고고학적 연구 결과를 바탕으로 역사문헌기록 속에서 난방관련 단어가 뜻하는 것에 대한 가설제안을 목표로 한다. 연구는 먼저 한국고전종합DB에서 한글 [온돌]에 대응하는 한자 검색자료를 문헌의 저작 년대별로 정리하여 종축으로 하고, 역사문헌이 지칭하는 지역을 횡축으로 하는 매트릭스를 작성하여 시계열적, 지역적 특성 분석하였다. 그리고 고고학적 자료를 바탕으로 종합 분석하여 결론을 도출하는 순서와 방법에 의했다. 첫째 시계열적 특성을 보면, 14세기까지는 <공간의 상태>를 의미하는 난방관련 단어(燠室)의 관찰빈도가 매우 높으며, 사물의 상태를 나타내는 난방관련 단어인 <溫突> 등은 14세기 초∼15세기 초 문헌에서 관찰되기 시작한다. 이후 15세기에는 <온돌> 등과 같은 사물의 상태를 나타내는 단어의 관찰빈도가 지속적으로 높아지는 반면, 공간의 상태를 나타내는<욱실(燠室)>과 같은 단어의 관찰빈도가 낮아진다. 그리고 16세기부터 18세기까지는 사물의 상태를 지칭하는<온돌>이라는 단어와, 공간의 상태를 나타내는 <온방(溫房)> 등의 단어가 동시에 관찰된다. 이와 같은 이와 같은 시계열적 지역적 특성은 고고학적 연구결과와 유사한 흐름을 가지고 있다. 따라서 역사문헌 기록 중의 <온돌>은 생활면으로 확장된 바닥으로 난방 및 축열, 배연기능을 갖는 난방설비를 지칭하며, <욱실>은 공간의 상태를 나타내는 단어로 생활 바닥면으로서 기능이 확대되기 이전 단계의 배연구조만 있는 난방설비가 설치되어 따뜻한 실내 환경을 지칭하는 것으로 이해해야 한다 In order to bring more light on the development of the Korean traditional housing and people’s lives in ancient times, we need to provide descriptions that tap into the intercomplementary combination of the archeological research results and philological research results. Accordingly, this thesis aims to put forward a hypothesis on what the heating related vocabulary means in the historical records, based on the Korean Classics Database and the archeological research results. The study first compiled the Sino-Korean search data matching the Korean ondol from the Korean Classics Database and took it as the axis of ordinates, and then, created the axis of abscissa from the regions referred to by the historical records. With these axes, the study created a matrix and analyzed the time-series and regional characteristics. The sequence and method of the study were such that a comprehensive analysis was performed on the archeological data, from which the conclusion was drawn. First, the time-series characteristics show that the heating-related term of uksil (燠室), which meant ‘the condition of space’, registered a very high frequency of observation until the 14th century. And those heating-related terms that describe the condition of things such as ondol (溫突) were not found in records until the early 14th century to the early 15th century. In the 15th century, those words that showed the condition of things such as ondol registered a continuously increasing frequency of observation, whereas words like uksil were observed with decreasing frequency. And between the 16th century and the 18th century, both the words like ondol referring to the condition of things and those like onbang referring to the condition of space were observed. And these time-series characteristics show a pattern that resembles the archeological research results. Therefore, we should understand that the term of ondol found in the historical records should be read as referring to the expanded floor in residential space, that is, the heating facility with heating, thermal energy storage, and smoke exhaust features, whereas the term of uksil that indicates the condition of space refers to the indoor space with heating facilities that include the smoke structure alone.

조원석 ( Won-suk Cho ) 대한무용학회 2021 대한무용학회논문집 Vol.79 No.1

This study is an empirical study on the effect of ballet movements using Grossman's technique on physical health factors. Through this study, participation in health care programs such as various dance performances and ballet movements was found to have a positive effect on physical, mental, social, and spiritual health promotion factors. However, this study has several limitations as follows. First, it was not possible to control the subjects' past health status and health capital by limiting the employment information source data. Second, the scale variables for health care program activities such as dance performance and ballet movement are limited. Third, ballet has limitations in the analysis of physical, mental, social, and spiritual factors in terms of overall health. Fourth, it can be heard that the observed value of the independent variable on which chronic disease the dance performance ballet movement is effective was not detected in advance.

2015년 제21차 기후변화협약 당사국 총회에서 채택된 `파리 협정(Paris Agreement)`을 준수하기 위해서는 세계적으로 CO₂의 배출량을 줄여야 한다. 일본은 2050년까지 60~80%의 CO₂배출 삭감을 목표로 에코하우스라는 친환경 시범하우스를 전국 20곳에 건설하여 친환경 건축기술 보급에 노력하고 있다. 우리나라도 CO₂감축노력에 동참해야 할 시점으로 주요한 선행 사례로서 일본 환경성의 환경공생형 주택의 건축설계기법을 분석할 필요가 있다. 이에 본 연구는 지역풍토 이해를 바탕으로 건설된 일본 환경성의 환경공생형 주택을 대상으로 건축설계기법을 분석하는 것을 목적으로 한다. 이는 우리나라 기후조건에 적합한 친환경주택개발에 필요로 하는 기초적 자료 제공에 그 의의가 있다. 연구방법은 문헌조사와 2차의 일본현지조사에 의했다. <일사량>과 <기온>으로 지역기후의 특성을 5단계로 나타내는 패시브 지역구분에 따라 각 지역의 에코하우스의 각부구조 및 단면구성을 분석한 결과 다음과 같은 것을 지적하였다. 자연에너지 활용, 자연건축소재 이용 등 CO₂감축을 위한 다양한 친환경 기법이 사용되고 있다. 특히 건축설계기법적 측면에서 보면, 일사량이 적고 추운지역(레벨 1, 2)에서는 겨울철 일사를 실내로 적극 도입하기 위해 남측에 큰 창을 설치하고 2층 바닥일부를 개방하고 있다. 그리고 지붕 복토(覆土), 벽체 통기층(通氣層) 설치 등 겨울철 실내 온도유지를 위한 축열 및 단열 등의 건축설계기법으로 많이 채택하고 있다. 이에 대해 일사량이 많은 지역(레벨 4)에서는 대부분 대면창(對面窓) 또는 일사 차폐(遮蔽)시설 설치, 지중냉열(冷熱) 활용 실내공기 강제순환시스템 등 여름철 실내 온도를 낮추기 위한 건축설계기법을 많이 채택하고 있다. To comply with the `Paris Agreement` adopted at the 21st Conference of the Parties to the Convention on Climate Change in 2015, it is necessary to reduce CO₂ emissions globally. Japan aims to reduce 60~80% of greenhouse gas emissions by 2050, and is making efforts to disseminate eco-friendly construction technology by constructing Eco-House, an eco-friendly demonstration house, in 20 locations nationwide. It is necessary to analyze the architectural design method of environment symbiotic housing of the Japan Environment Agency as a principal precedent case when Korea should join in CO₂ reduction efforts. Thus, the purpose of this study is to analyze the Japan Environment Agency`s architectural design techniques of the environment symbiotic housing which was constructed based on the understanding of local climate. This is meaningful in providing basic data needed for development of eco-friendly housing suitable for Korea`s climate conditions. The research method was based on the literature survey and the two field surveys in Japan. Based on the analysis of the structure and cross-sectional structure of the eco-house in each region according to the passive area classification showing the five stages of characteristics of the local climate by the “solar radiation” and “temperature”, the following points were pointed out. Various eco-friendly technologies for CO₂ reduction are being used, such as utilization of natural energy and utilization of natural building materials. Especially, from the viewpoint of architectural design technologies, large windows are installed on the south side and a part of the second floor is opened to positively introduce winter solar radiation into the indoor areas in cold regions with low radiation (levels 1 and 2). Roof earth sheltering (覆土) and installation of wall ventilation layer (通氣層) are widely adopted as architectural design techniques such as heat insulation and insulation for maintaining indoor temperature in winter. On the other hand, many architectural design techniques for lowering the room temperature in the summer, such as installation of facing windows (對面窓) or solar shielding (遮蔽) facilities, and indoor air forced circulation system using underground cold heat (冷熱) are adopted in regions with high radiation (level 4).
