한국(韓國) 전통(傳統)의 자연관(自然觀)과 인간관(人間觀)

김명호,Kim, Myungho 사상체질의학회 1996 사상체질의학회지 Vol.8 No.1

Culture is way of life. And a culture is based on the view of nature and humun being. Korea has many kinds of tradition. Out of them, Korean character Hangul, food and medicine have been succeeded as they were in old days. So I tried to induce Korean view of nature and human being from those traditions. The common principle induced from them is Yin-yang and five elements. Yin-yang and five elements is away to cognize nature by Korean people. That means Yin-yang is thought to be the principle of nature. Nature is what life is born or produced. And mankind is a part of nature. Thus Yin-yang and five elements works on mankind in the same way as they do on nature. Mankind is born and grows on the earth. So human body consists of four, parts of the earth, which are light, air, water and soil. It is essential for human being to maintain balance and harmony in nature with nature and as nature.

터보팬엔진 기본설계 단계에서 로터 동특성을 고려한 로터시스템 설계 절차를 제안하였다. 터보팬엔진 로터 동특성 기본 설계 절차는 로터시스템 형상 설계와 엔진 동특성 해석 순으로 진행하였다. 로터 형상 설계과정에서 CAD를 통한 압축기, 터빈의 허브와 블레이드, 축방향 위치 등을 참조하여 샤프트와 베어링, 디스크, 씰 구조물 등으로 구성된 로터 형상을 설계하였다. 로터 동특성 해석과정에서 검증된 동특성 해석 프로그램으로 로터시스템의 위험속도선도를 분석하였고, 로터시스템과 엔진 재설계 여부를 판단하였다. The design procedures of the engine rotor systems were proposed in the preliminary design for the turbofan engine. The preliminary design process of the turbofan engine rotors consisted of the geometry design and the analysis of the rotor dynamics for the turbofan. In rotor system design, the rotor geometry included the shafts, bearings, disks and seal structures etc were designed to refer the hub line, blades and axial positions of the compressors and turbines used a CAD. In the analysis of the rotor dynamics, the campbell diagrams were investigated using the verified rotor dynamics program and the possibility of the re-design for the rotor systems or turbofan engine was considered.

중국 초기 선종(禪宗)의 농선병중(農禪幷重) 고찰

김명호(法志)(Kim Myungho) 원광대학교 원불교사상연구원 2018 원불교사상과 종교문화 Vol.75 No.-

본고에서는 중국 선종의 특색 가운데 하나인 ‘농선(農禪)’에 대하여 고찰하였다. 황매선(黃梅禪)을 중국 선종의 본격적인 출발로 삼는 것은 달마(達摩) 이후 능가사(楞伽師)들이 수립한 두타행(頭陀行)의 전통을 따르지 않고 한곳에 거주하여 공동체 생활양식을 취한 것과 관련이 있다. 이러한 공동체의 생활은 승려들이 노작(勞作)을 제창하고, 노작을 통해 자급자족하였다. 이는 경제적으로 신도들의 재시(財施)로부터 독립할 수 있는 조건을 형성하였으며, 이로부터 새로운 조사선풍을 수립할 수 있게 하였다. 이후 ‘노작’은 육조혜능(六祖惠能)을 거쳐 ‘일화오엽(一花五葉)’의 오가(五家)가 분등선(分燈禪)에 이르면서 선리(禪理)를 깨닫게 하는 ‘농선(農禪)’으로 정착하게 되었다. 그에 따라 ‘농선’은 중국선의 특질 가운데 하나로서 칭해진다. 그에 따라 본고에서는 ‘노작’으로부터 ‘농선’으로 전개됨을 선종의 본격적인 출발이라고 할 수 있는 황매선(黃梅禪)으로부터 위앙종(潙仰宗)에 이르기까지의 과정을 고찰하였다. 초기의 선종은 독자적인 사찰을 지니지 못하여 율사(律寺)에 종속되어 있었다. 그러나 마조(馬祖)가 총림(叢林)을 세우고, 백장(百丈)이 청규(淸規)를 세워 승려들의 ‘노작’으로 자급자족을 이룸으로서 비로소 선종사찰로서 독립할 수 있게 되었다. 따라서 ‘노작’은 율종도량으로부터 독립하기 위한 방편이었다고 할 수 있다. 이렇게 형성된 ‘노작’은 후대로 전해지면서 ‘농선’의 선수행으로 전개되었다고 하겠다. 이러한 ‘농선’은 단순한 노동이 아니라 그대로 선수행으로 향상일로(向上一路)하였음을 볼 수 있으며, 이는 현대에서도 여전히 중요한 의의가 있다고 하겠다. The writer researched ‘Farming Chán(農禪)’, one of the characteristics of Chinese Chán in this paper. Huángméi Chán(黃梅禪) is counted as a real starting point of Chinese Chán because ‘Lankavatara teachers (楞伽師)’ had not followed the tradition of ‘dhuta practice(頭陀行)’ but had settled down in one place taking a community lifestyle after Bodhidharma(達摩). In this community lifestyle, Buddhist monks proclaimed ‘work(勞作)’ and they could have been self-sufficient. It had formed the condition to stand without financial offering of Buddhists and it enabled to establish a new trend of Patriarchal Chán. After then ‘work(勞作)’ had took root as ‘Farming Chán(農禪)’ to realize the truth of Chán, going through Huineng, the sixth patriarch of Chán, and getting to ‘Fēndēng Chán(分燈禪)’ by five sects of ‘one flower with five leaves(一花五葉)’. Thus ‘Farming Chán(農禪)’ is hailed as one of the characteristics of Chinese Chán. Therefore the writer considered the process of development from ‘work(勞作)’ to ‘Farming Chán(農禪)’ through inquiring into the process from Huángméi Chán(黃梅禪), as a real starting point of Chán, to Wéiyǎng Zōng(潙仰宗). The early Chán had been subordinated to ‘Sila Vinaya temple(律寺)’ because they didn’t have their own temples. But Mǎzǔ(馬祖) had built the assembled monastery(叢林) and Bǎizhàng(百丈) had set up Pure Rules(淸規) so that they could have been self-sufficient. Finally they could stand alone from the temples of Chán. Thus we can say that ‘work’ is one measure to stand alone from ‘Sila Vinaya temple(律寺)’. With passing down of their ‘work’ tradition to the next generation, they could develop practice of farming Chán(農禪). This farming Chán(農禪) is not the simple work, but the revolutionary Chán practice as it is. It has an important significance in these modern times as ever.

김명호(Myungho Kim),김규태(Kyu Tae Kim) 한국연소학회 2022 KOSCOSYMPOSIUM논문집 Vol.2022 No.5

The present study is concerned with the low-frequency self-excited instabilities frequently occurring in aero-engine combustors operated with Jet A-1 fuel under pilot-mode non-premixed conditions. To investigate key aspects of combustion instabilities related to dual-swirl spray flames, we analyze the entire instability dataset collected over the broad range of operating conditions. We show that the development of low-frequency instabilities is attributable to the interaction between several distinctive reaction regions with different characteristic timescales.

김명호(Kim MyungHo) 한국지역개발학회 1994 韓國地域開發學會誌 Vol.6 No.1

Kwangyang Bay Region, located on the Southern Cost of South Korea, has been growing rapidly through extensive industrialization. Since the 1980s this region has acquired two major development projects, i.e., Yusoo Petrochemical Industrial Park and Pohang Steel and Iron Company. This region has additional potential for further growth bcause of the good port conditions in Kwangyang Bay and the sufficient supply of industrial lands around the Bay. This research has attempted to evaluate the government policies and plans for managing this region. It concludes that governmental approach to this region has been very inconsistent. Planned scale of Kwangyang Port has been vary from plan to plans and implementation of plans for individual projects has been often delayed. In order not to loose opportunities of further growth for the southwestern provinces of Korea the central government has to commit its efforts to the development of Kwangyang Bay Region.

김명호(Myungho Kim),임주현(Juhyun Im),김용련(Yeongryun Kim) 한국추진공학회 2015 한국추진공학회 학술대회논문집 Vol.2015 No.5

가스터빈 엔진의 냉각터빈 효율은 터빈 입구 유동에 냉각유동이 추가되어 일반적인 입·출구조건으로는 터빈 효율 정의가 맞지 않아, 기존 문헌에 제시된 냉각터빈 효율의 정의와 차이점을 검토하였고, 엔진사이클 성능 정의에 필요한 냉각터빈 효율을 정의하고자 하였다. 효율 검토를 위해 적용한 터빈은 1단 고압터빈으로 노즐과 블레이드 모두 내부 냉각 채널이 구성된 필름냉각 방식이며, 터빈 입구온도가 1,600K 인 고하중 터빈이다. 냉각터빈 효율 분석을 위한 터빈 유동해석은 냉각채널이 없는 에어포일 벽면의 냉각 효과를 감안하고, 설계 시 반영된 입·출구 경계조건과 노즐과 블레이드의 냉각 유량이 주유동과 혼합되는 유동을 모사하였다. 터빈부의 각 지점 온도와 압력, 유량 등의 공력해석결과를 활용하여 기존 제시된 냉각터빈 효율 정의에 의해 효율값을 산출하였다. 엔진사이클용 터빈 성능맵을 제시하기 위해 계산된 효율을 비교하였고, 엔진 사이클 성능 평가에 활용하였다. 정립된 효율 정의는 리그시험과 코어엔진시험의 성능 평가 시 효율 산출을 위한 기초자료로 활용하고자 한다. The efficiency of the cooled turbine should be defined considering both the properties of the main flow and the cooling flow. In this respect, the various methods for defining the cooled turbine efficiency have been discussed in the papers and technical reports. In this study, the various definitions of cooled turbine efficiency are reviewed, discussed and compared for the single-stage high pressure turbine with film cooling. To decide the turbine efficiency, the pressure, temperature, and mass flow rate at the turbine inlet and exit were obtained from Computational Fluid Dynamics (CFD) calculation. In the CFD calculation, the mixing process between the main and cooling flows in the turbine was simulated. The cooling turbine efficiencies deduced from the various definitions were quantitatively compared, and applied to engine cycle performance evaluation. The adequate definition of the cooled turbine efficiency will be used for performance evaluation at rig and core-engine tests.
