        12수종에 대한 단벌기 (短伐期) 맹아림의 (萌芽林) Biomass 생산

        현영일,김재헌,한영창,이경준 ( Young Il Hyun,Jae Hun Kim,Young Chang Han,Kyung Joon Lee ) 한국산림과학회 1982 한국산림과학회지 Vol.55 No.1

        Wood biomass production at 1-year, 2-year, and 3-year rotations on both low and upper hills at 2m × 2m spacing (25,000 trees/ha) was studied for a six-year period with following 12 species; Lespedeza cyrtobotrya Amorpha fruticosa. Robinia pseudoacacia, Acer saccharinum, Platanus orientalis Populus alba x P. glandulosa F₁, Salix alba, Pinus rigida, Alnus hirsuta var. sibirica, A. inokumai A. gultinosa, and A. incana. In One-year rotation, Lespedeza cyrtobotrya produced largest amoung of biomass (2.6 t/ha/year, fresh weight) and Populus alba x P. glandulosa F₁ the second largest (2.2 t/ha/year) on low hill. In two-year rotation, the latter produced the largest amount (4.8 t/ha/year) and Alnus hirsuta var. sibirica second largest (2.8 t/ha/year) on low hill. In three-year rotation, the largest weight (11.2 t/ha/year) was produced by Robinia pseudoacacia and the second largest (6.2 t/ha/year) by Alnus hirsuta var. sibirica on low hill Amorpha fruticosa, Acer saccharinum, Platanus orientalis and Salix alba were not suitable for biomass or fuelwood productio due to poor growth. Biomass yield on upper hill was reduced considerably for all tewlve species, with less than 4 t/year at maximum Only nitrogen fixing species (Robinia and Alnus species) are recommended on upper hill for biomass production wood sprouting ability of species was generally associated with good biomass production. Calori values of ovendry wood ranged from 4,485 cal/g for Salix alba to 5,125 cal/g for Alnus glutinosa. For maximum biomass production a three-year ratation with coppice is preferred to one-year and two-year roataions The best species appeared to be Robinia pseudoacacia and Alnus hirsuta var sibirica.

        『新刊類編歷擧三場文選對策』의 書誌的 硏究

        현영 明知大學校 人文科學硏究所 2005 인문과학연구논총 Vol.27 No.-

        A bibliographical research has been done in this thesis on "SinGan YooPyun-YoukGueSamJangMunSun-DaeChack", a reference book for the high public service examination. This, by analyzing the book’s kinds of edition, intends to be a basis for examining closely the characteristics and values of the reference book, which has become a part of the Chosun Dynasty printing history. For the study, the kinds and the subjects of the high public service examination---which had become the publication background of the Chosun Dynasty---have been closely examined. Thus the importance of the writings on scheme---a subject of the final examination which was the last barrier of the civil service examination under the kingdom---has been recognized. Taking this social background into consideration, research has been done on the existing books of "SinGanYooPyun-YoukGue SamJangMunSun-DaeChack", the collection of writings about the policy of a nation, and analysis has been made on the book’s kinds of edition. Through the study, it is confirmed that the Kemija book and the reviving wooden publication from Kougjaja book of the "SinGanYooPyun-YoukGueSamJangMunSun-DaeChack" have been handed down, which means they were published many times in the Chosun Dynasty becoming the main stream of reference books for the high public service examination. The examination started to be held in the Koryo Dynasty and became in the early Chosun Dynasty the work of devotion in appointing civil ministers.

        The traditional Oriental materials are very important for the study on the Oriental or Korean Studies. It is essential that every reseacher studying this field must be familiar with the methods of using the traditional bibliographies. Specially, the control of bibliographies is very important in the present when we have the flood of the materials. Purpose of this study is to encourage the use of traditional oriental materials and developt the modern control of traditional oriental bibliographies. The study is to examine the origins and the developing processes of Shih(史:Histories), Tzu^(子:philosophers) in Chinese traditional bibliographies and to compare to Korean traditional bibliographies.

      • 국산화를 위한 회전익 항공기 와이퍼 암 조립체 피로강도 입증

        현영,김상훈,이성운,황유상,문연호,홍기영 한국항공우주학회 2015 한국항공우주학회 학술발표회 논문집 Vol.2015 No.11

        항공기에 사용되는 부품은 주구조물 (PSE: Principle Structure Elements) 과 반복하중을 받는 일부 외부 장착물에 대해서도 관련 규격에 따라 매우 가혹하고, 엄격한 피로강도 입증절차를 거쳐 개발된다. 회전익항공기 윈드쉴드에 전면부에 장착된 와이퍼 조립체는 우천 시 또는 악천후 조건에서 시계확보를 위한 주요 품목으로 파손이 될 경우 엔진 흡입구로 빨려 들어가 운항 중인 헬기에 심각한 영향을 줄 수 있기 때문에 비행안전부품(FSP: Flight Safety Part) 입증절차와 동등한 수준의 요구도로 개발된다. 본 연구에서는 우천 또는 악천후시 필수 외부장착물인 윈드쉴드 와이퍼 암 조립체의 국산화 개발과정에서 수행된 해석적 평가 내용 및 피로 강도시험 결과에 대하여 기술하였다. The PSE of aircraft and some external components affected by cyclic load are conservatively developed according to the associated regulations. In case of the wiper assembly attached on the windshield front surface, as it is regarded as one of the important part for flight safety to overcome poor weather condition like the rainy or any other bad vision condition and it could cause a serious consequence of helicopter when it is broken and then it"s particles are sucked in the engine inlet, it should be developed to satisfy the equivalent requirement of FSP. It is described in this study that the analytical fatigue evaluations and durability test results and comparisons of windshield wiper ass"y for localizing which is necessary external component under rainy or any other bad vision condition.

        스피노자의 감정 치료법

        현영 서양근대철학회 2019 근대철학 Vol.13 No.-

        In this article I would like to suggest the meaning and significance of therapy of passions in Spinoza’s Ethics. According to Ethics V this therapy consists of the understanding of our intelligence. This process of therapy, however, should be elucidated not on the aspect of simple cognitions, but on the layer of the dynamics of affective powers of such cognitions. An affect can be alleviated only by an opposite and stronger power of other affects. In this sense, the therapy of passions in Spinoza’s Ethics V is a method for a negative freedom which means removal of obstacles. However, this therapy should be understood in Spinoza’s salvation project. The reason is why the process of this remedy is the active realization of intellect and self-consciousness development, which means positive freedom or beatitude. 나는 이 논문에서 스피노자의 『윤리학』5부 전반부의 감정 치료법이 갖는 의미와의의를 제시하고자 한다. 스피노자는 감정 치료가 전적으로 지성의 참된 인식에의존한다고 말하고 있다. 그런데 이러한 치료는 단순한 인식의 층위에가 아니라, 그러한 인식에 수반하는 정서적 동역학의 층위에서 이해되어야 한다. 정념은 오로지 반대의 그리고 더 강한 다른 감정에 의해서만 억제될 수 있다. 스피노자의감정 치료법은 방해물의 제거를 뜻하는 소극적 자유를 위한 수단이다. 하지만 이치료법은 동시에 지성의 능동적 실현이자 자기의식의 전개로도 간주될 수 있다. 이러한 의미에서 감정 치료는 적극적 자유 혹은 지복을 위한 구체적인 실천 방안이다.

      • Strain Gauge Type 傾斜計의 振動特性에 관한 硏究

        Challenge and Response in Quality Management at Hyundai Motor in the 2000s

        현영,김진호 충남대학교 경영경제연구소 2016 경영경제연구 Vol.38 No.1

        Hyundai Motor, in spite of its late entrance to the automobile industry in 1967, has grown very rapidly to become the 5th largest auto maker in 2009 with its affiliated company, Kia Motor. It has kept its ranking in 2014, producing 8 million vehicles. Hyundai has met many diversified crises since its foundation as a late entrant into the market. It also met multiple crises during the turmoil of the IMF bailout in the late 1990s, including a quality crisis. The purpose of this paper is to analyze the crises and innovation in quality management at Hyundai during the period from 2000-2015 by way of an in-depth case study. The quality crisis induced Hyundai to reshuffle the quality management system. This reorganization can be classified into 3 generations. The first generation was focusing on getting over the crisis by reducing the number of defects during the period from 2000-2007. The second generation was focusing on quality marketing campaigns to enhance corporate brand value during the years from 2008-2010. The third generation aims to introduce a new global quality management system and has been ongoing since 2011. The findings of this study are as follows. First, it was found that this case study supports the challenge and response paradigm, a resource-based view of the firm, and Garvin’s evolutionary perspective in quality management. Second, this case also supports Aaker’s proposition about quality-brand-industry leadership relations: Some time is needed to pass until the profit due to quality management efforts is realized. Third, it shows that the strong leadership of the founding family was one of the important resources for accumulating capability to overcome the quality crisis through dynamic learning. Hyundai was able to transform a quality crisis into a stepping stone opportunity for a turnaround in the U.S market, as well as an aggressive globalization in the 2000s.
