The government is pursuing a greenhouse gas reduction policy in accordance with the agreement adopted at COP21 held in Paris in 2015. Therefore, public institutions are required to install new and renewable energy facilities, and the ratio of obligations is being gradually expanded every year. KEPCO operates a regenerative braking device support system that reduces power demand through demand management. Regenerative power is the surplus power generated when the elevator is operated. The total regenerative power capacity of the elevator that can be produced in Korea is 1GW, which is equivalent to one unit of Shinwol Sung nuclear power plant (1GW). In the case of existing 15-storey apartments, the electricity consumption of the elevator is about 4% of the total electricity consumption of the apartment and 25% of the public electricity. The monthly average monthly usage of one elevator is equal to or more than the average monthly usage of the first generation. The regenerative power increases in proportion to the amount of elevator usage. When an apartment is paid for installing a regenerative power module, it is difficult for the apartment to recover the cost of installing the regenerative power module quickly due to the power saving cost. Therefore, it is only economically effective to utilize the regenerative braking device support system implemented by KEPCO. In the case of a newly installed elevator, a regenerative power type elevator must be installed, Conventional elevators should contribute to minimizing the energy use of the building while minimizing the investment cost by installing regenerative power modules through the regenerative braking system support project.

승강기 리모델링을 위한 최적 시기에 관한 연구

김한진(Han-Jin Kim),최옥만(Og-Man Choi),이안기(An-Ki Lee),김재철(Jae-Chul Kim) 한국조명·전기설비학회 2017 조명·전기설비학회논문지 Vol.31 No.11

In 2016, there are 600,000 elevators installed in Korea. Of these, more than 30,000 elevators are newly installed or completely replaced each year because the percentage of old elevators exceeds 30%. However, the owner of the elevator often misses the optimal time due to the lack of expertise and data on how to replace or replace the old elevator. Also, the risk of safety accidents due to the aging of elevators is increased. Although the maintenance of the elevator is carried out monthly, the risk of a safety accident is increasing because the lowest cost is paid for troubleshooting and maintenance. For this reason, it is important to predict the life expectancy and replacement timing of the elevator, and to provide information so that the elevator can be replaced at the optimum time, in order to prevent accidents. Through the fault data of the elevator, Cumulative failure probability can be estimated by ‘Kaplan-Meier’ estimation method, ‘Weibull’ distribution analysis can be used to predict life expectancy. Age Replacement Method can determine the optimal time of economic life. The greater the preventive replacement rate, the less the risk of accidents and the longer the economic life span.

김한진(Kim, Han-Jin),이동건(Lee, Dong-Gun) 동아대학교 스포츠과학연구소 2008 스포츠科學硏究論文集 Vol.26 No.-

본 연구는 체육학적 관점에서 이루어진 퇴계 연구의 동향을 파악하고, 이를 통하여 퇴계 연구의 중요성을 재확인하며, 나아가 추후 퇴계 연구의 방향을 설정하여 보다 심층적인 연구가 이루어질 수 있도록 하고자 하는 목적을 가지고 ‘퇴계’와 ‘이황’의 주제어를 사용한 선행연구를 중심으로 타 학문적 관점에서의 퇴계연구와 체육학적 관점에서의 퇴계 연구로 구분하여 연구·분석한 결과 다음과 같은 결론을 얻을 수 있었다. 먼저, 타 학문적 관점에서의 퇴계 연구의 동향은 첫째, 연구관점별로는 대부분의 경우 퇴계의 전반적인 사상론에 기초하여 신체관이나 심신관에 대하여 연구되어지고 있었으며 둘째, 연도별로는 1980년대와 1990년대보다 2000년대 진입하여 더 많은 연구가 이루어지고 있었다. 끝으로, 연구주제별로는 자연과학보다는 인문·사회과학의 연구가 많았으며, 그 가운데에서도 체육철학-체육교육-활인심방·건강법·기공법-체육심리학의 순으로 연구가 이루어지고 있음을 알 수 있었다. 또한, 퇴계 연구가 현대 사회의 문제점으로 지적되고 있는 지나친 개인주의, 객관주의 등을 뛰어 넘어 새로운 방법을 제시할 수 있는 하나의 대안이 될 수 있다는 점에서 그 중요성을 재확인할 수 있었으며, 앞으로의 연구에서는 지금까지 대부분의 연구가 인문·사회과학 영역에 집중되어져 있었던 것에서 벗어나 보다 다양한 영역에서의 연구가 이루어져야 할 것이다. This study examines the trend of the research on T'oegye from the gymnastic view and reassures the importance of the research on T'oegye. Based on the previous study on the key words such as T'oegye and Yi-hwang, this study is divided into two areas: other academic and gymnastic approach to T'oegye. Through this procedure, the purpose of this study is to establish the direction of T'oegye research for the more in-depth study in the related area later and the following conclusion could be obtained by this study. First of all, other academic research on T'oegye ideology has been done by the philosophical perspective of T'oegye ideology through the study on Confucianism and by humanics analysis and religious research on T'oegye ideology. Next, the trend of the study of T'oegye in the gymnastic view can be summarized as follows. First, much of research of T'oegye is focused on the view of body and the mind on the basis of general T'oegye's ideology. Second, there were more research in 2000's than between 1980's and 1990's in the chronological classification. Lastly, the research classified by research topic has been much more done in the humanities and social sciences than the one within natural sciences. Among them, the mainly concentrated parts can be in other as follows: Physical philosophy, Physical education, Hwal-In-Shim-Bang, Maintaining health, Ki-Kong method, Physical psychology. This study also points out that T'oegye research can be an new alternative way for overcoming the current severe social problems such as individualism and objectivity in modern society. In the end, I suggest that the further study on T'oegye should be conducted from the humanities and social sciences to the more various academic fields.

퇴계의 체육교육사상에 관한 연구

김한진(Kim, Han-Jin),이동건(Lee, Dong-Gun) 동아대학교 스포츠과학연구소 2008 스포츠科學硏究論文集 Vol.26 No.-

본 연구는 현대 한국 체육교육이 무비판적으로 받아들인 서양 체육사상에 의해 기능적으로만 우수한 인간을 만들어내는 현상에 대한 반성으로부터 시작하여 그 해결점으로 한국 고유의 독자적 사상체계 중 퇴계의 교육사상에 주목하였다. 퇴계사상에 기반을 두고 있는 철학인 이기론·심성론·경사상에서 나타나고 있는 교육목적을 고찰하고 그것이 현대 체육교육에 주는 의미를 살펴 본 결과는 다음과 같다. 퇴계사상은 이(理)와 기(氣)는 서로 떠날 수 없는 관계로 상호작용을 통해서만 진정한 하나의 의미가 될 수 있다는 이기호발설(理氣互發說)적 입장으로 인간능력에 대한 신뢰를 전제로 한다. 몸과 마음은 통합적이고 조화로운 존재로서 서로는 상호의존적 관계라는 맥락에서 퇴계의 사상에 함축되어 있는 체육교육의 목적은 진정한 인간의 모습이란 활동을 통하여 이루는 자아실현이라고 정리할 수 있다. 퇴계의 체육사상은 현대 한국의 체육교육목적에 가장 근접한 사상이다. 퇴계의 사상에서는 신체적인 단련뿐만 아니라 그 속에 스며있는 정신적인 면도 함께 발달시켜야 한다고 주장하고 있으며 이를 구체적으로 실천하기 위한 방법으로 거경(居敬)과 궁리(窮理)를 들고 있다. 퇴계는 그의 사상에서 신체적·지적·정서적·윤리적으로 결합된 완전인인 성현을 기르는 것을 목적으로 신체적인 것에 대한 관심을 부정하지 않고 체육활동을 중요시하였기에 퇴계의 체육교육사상은 성현으로서의 사람을 살리는 학문이라는 뜻인 활인지학(活人之學)으로 설명할 수 있다. This study started from reflection of making a superior human only in functional part by western ideology that modern Korean physical education accept uncritically. According the needs of time, the study focused on T'oegye's thought of physical education among the Korean unique system of thought. With looking into Li-Gi-Theory, the Meaning of Mentality and Kyoung-Throry which the thought of T'oegye stand on the basis of, this study makes clear his objective of education and the meaning that affect to the modern physical education are as follows. The thought of T'oegye is in Li-Gi-Ho-Bal-Theory that a reason(Li) and spirit(Gi) can become a true one through the interaction. So the reason assumes the confidence of human's abilities. It says that a body and heart are unitive and harmonious existences and they are interdependent. According this thought, the object of physical education in the thought of T'oegye is that a real human's feature is self-realization through the activities. T'oegye's physical thought is the nearest idea in the object of modern Korean physical eduation. In T'oegye's thought he insisted a physical discipline has to be developed with spirit and he thought JuJing(The exercise of seriousness) and QiongLi(The investigation of priciple) is the way to practice concretely. T'oegey's thought of physical education took a serious view of physical parts not to deny the interests about physical things. That is to raise the saints who combined physically, intellectually and morally. So, it can be explained with Hwal-in-ji-yak which is the study saving person as saints.

김한진(Han-Jin Kim),장영범(Young-Beom Jang) 대한전자공학회 2010 대한전자공학회 학술대회 Vol.2010 No.6

In this paper, we propose a new mura detection algorithm for TFT-LCD effectively, which is based on multi-point, 2-dimensional FFT. Since mura in TFT-LCD has a certain area shape, it is seen as a sin wave in a LCD line. Since shapes of mura can be seen a circle, horizontal oval, or vertical oval, it is shown that they can be detected by 2-dimensional FFT easily. Through simulation for test image, it is shown that proposed algorithm can detect various sizes of mura. The proposed algorithm can be utilized in automatic test equipment for effective TFT-LCD mura detection.
