한상호,주형근,Han, Sang-Ho,Joo, Hyung-Kun 한국디지털정책학회 2022 디지털융복합연구 Vol.20 No.4

본 연구는 국내 사정에 적합한 스마트팜 기술 전략을 ICT 기술의 국내 사정에 적합한 차별화를 중심으로 제안하고자 했다. 해외 농산업 선진국의 경우 각 나라의 지형적 특성, 농산업 특성, 국민 수요 특성 등을 전반적으로 반영한 특정 단계 개발에 주력함을 확인했으나, 국내 스마트팜의 경우 해외 기술을 여과 없이 수용하여 국내사정에 적합한 기술의 선별적 개발이 수행되지 않음을 확인했다. 따라서, 본 연구는 국내 농촌 인구의 급격한 감소, 인구 고령화, 농작물 가격 경쟁력 상실, 휴경지 증가, 경지 이용률 감소 등 문제에 따라, 차후 스마트팜 ICT 기술 개발 방향성을 품질 좋은 농산물을 창출하여 가격 경쟁력을 갖추기 위한 성능의 우수함, 노동인구 고령화에 따른 사용의 용이성, 영세한 경영규모에 적합한 경제성 등에 주목하여 스마트팜을 추진해야 함을 제시했다. 첫째, 경제성 차원에서 영세농가(1차) 경영환경에 필요한 기능들만 선별하여 ICT 기술을 구성하고, 이들과 원활한 의사소통 체계를 ICT 기술에 적용하여 실제 농가에서 필요로 하는 기능을 점차적으로 업데이트함으로써 비용 감소에 일조할 수 있음을 제안했다. 둘째, 성능차원에 있어서는 국내 고령화 인구에 적합한 빅데이터 난이도 조절, 이들에게 적합한 언어사용, 이들의 예측 성향을 반영한 알고리즘 설정 등 ICT의 의사소통 기능 개선에 주목한다면 작동 정확성을 증대할 수 있음을 제안했다. 셋째, 사용용이성 차원이다. 6차산업(1차(농업,임업)+2차(농수산물가공)+3차(서비스,농어촌체험,유통)) 발전을 위한 ICT 기술에 기반한 스마트팜은 특정 명령어에 따라 동작을 수행하는 바, 특정 명령에 빅데이터에 근거한 추론을 통한 추가적 기능들이 자동적으로 수반될 것과, 각 지역적 환경에 맞춤화된 빅데이터 구성에 기반한 장치를 미리 세팅, 표준화하여 사용용이성을 촉진할 수 있음을 최종 제시했다. This study tried to propose a smart farm technology strategy suitable for the domestic situation, focusing on the differentiation suitable for the domestic situation of ICT technology. In the case of advanced countries in the overseas agricultural industry, it was confirmed that they focused on the development of a specific stage that reflected the geographical characteristics of each country, the characteristics of the agricultural industry, and the characteristics of the people's demand. Confirmed that no enemy development is being performed. Therefore, in response to problems such as a rapid decrease in the domestic rural population, aging population, loss of agricultural price competitiveness, increase in fallow land, and decrease in use rate of arable land, this study aims to develop smart farm ICT technology in the future to create quality agricultural products and have price competitiveness. It was suggested that the smart farm should be promoted by paying attention to the excellent performance, ease of use due to the aging of the labor force, and economic feasibility suitable for a small business scale. First, in terms of economic feasibility, the ICT technology is configured by selecting only the functions necessary for the small farm household (primary) business environment, and the smooth communication system with these is applied to the ICT technology to gradually update the functions required by the actual farmhouse. suggested that it may contribute to the reduction. Second, in terms of performance, it is suggested that the operation accuracy can be increased if attention is paid to improving the communication function of ICT, such as adjusting the difficulty of big data suitable for the aging population in Korea, using a language suitable for them, and setting an algorithm that reflects their prediction tendencies. Third, the level of ease of use. Smart farms based on ICT technology for the development of the Industry6.0 (1.0(Agriculture, Forestry) + 2.0(Agricultural and Water & Water Processing) + 3.0 (Service, Rural Experience, SCM)) perform operations according to specific commands, finally suggested that ease of use can be promoted by presetting and standardizing devices based on big data configuration customized for each regional environment.

한상호,전중환,최종술 ( Sang Ho Han,Joong Hwan Jun,Chong Sool Choi ) 한국열처리공학회 1994 熱處理工學會誌 Vol.7 No.2

Five alloys were selected randomly in the composition range showing the best shape memory effect in Fe-Mn-Si system reported by Murakami. The shape memory effects of those alloys were mainly investigated through the training treatment which consisted of the repetition of 2% tensile deformation at room temperature and subsequent annealing at 600℃ above A_f temperature. At the same deformation degress in rolling 600℃-annealing for 1hr. showed the best shape memory effect, and 10% deformation degrees represented maxima of the shpae memory effects at all annealing temperatures, 500℃, 600℃ and 700℃. The shape memory effects of the alloys were increased by increasing training cylcle up to 5 cycles. This was because a large number of dislocations introduced by training process gave rise to increase in the austenite yield stress, and acted as nucleation sites for stress induced s martensite. The thermal cycling treatment, repetition of cooling in nitrogen at -196℃ and heating to 300℃ for 5 min., did not improve the shape memory effect.

읽을거리 - 항공기 실전원리(8) - 낙뢰와 항공사고 -

한상호,Han, Sang-Ho 한국항공우주산업진흥협회 2009 航空宇宙 Vol.103 No.-

장마와 태풍의 계절 여름. 특히 하늘을 짖기라도 하듯 어마어마한 전기를 일으키는 낙뢰를 하늘을 나는 항공기로서는 정말 위협적인 존재가 아닐 수 없다. 하지만 낙뢰를 알고 이에 대한 철저한 보호대책이 따른다면 낙뢰에 의한 항공사고는 충분히 줄일 수 있다.

영어교육 연구와 실천의 불이적 세방화 논의

한상호(Han Sang-Ho) 팬코리아영어교육학회(구 영남영어교육학회) 2006 영어교육연구 Vol.18 No.4

  This study presents a wavicular approach to glocalization of research-practice in English education. The author argues against the trends of globalization which tend to be unidirectional imposition of predominant Anglo-European perspectives of English language teaching. Upon critical analysis of the term glocalization, the author reveals that hidden agendas of neoliberal commercialism reside at the heart of the term itself. As a consequence, he proposes that the concept of glocalization should be reconstituted with locally sensitive attributes such as subjectivity, self-direction, critical awareness, along with that of intercultural understanding, which have been excluded in the usual value-neutral sense. Following an analysis of aspects of glocalization represented in some of keynote and plenary presentations at major English education conferences in Korea from 1997 to 2002, the author suggests the following wavicular approach to glocalization of research-practice: 1) establishing ownership of research-practice on the part of teachers, 2) reaching the state of Nirvana in research-practice, 3) accomplishing learner-centered English education through application of ‘natural’ taoistic teaching, 4) attaining the Tao awareness of teaching as language teacher, 5) developing receptivity toward students" identities, 6) fostering learner autonomy and authenticity in the learning and use of English, and 7) making students constantly cross the bridge between localness and globalness.

히든챔피언의 내부 및 외부지배구조에 따른 무형자산성 지출의 가치관련성

한상호 ( Sang-ho Han ),나영 ( Young Na ) 한국회계학회 2021 회계저널 Vol.30 No.3

본 연구는 히든챔피언(강소기업)의 내부 및 외부지배구조에 따른 무형자산성 지출에 대한 가치관련성을 검증하였다. 이를 위해 먼저 코스닥 상장기업 전체를 대상으로 내부 및 외부지배구조가 기업가치와 관련성이 있는지를 분석하였다. 또한 코스닥 상장기업 중 한국거래소에서 선정한 강소기업을 ‘강소기업’ 표본으로 하고, 성향점수매칭(PSM) 기법을 사용하여 강소기업 표본에 대응되는 통제기업을 ‘일반기업’ 표본으로 선정한 후, 내부 및 외부지배구조의 가치관련성이 강소기업과 일반기업 간에 차이가 있는지를 분석하였다. 그러고 난 후, 강소기업 표본을 대상으로 2단계 회귀분석(2SLS)을 통해 강소기업의 내부 및 외부지배구조가 무형자산성 지출을 증대시킴으로써 기업가치가 유의하게 증가하는지를 심층적으로 검증하였다. 연구결과를 요약하면 다음과 같다. 첫째, 코스닥 상장기업의 내부지배구조(이사회규모, 사외이사비율 및 최대주주지분율)와 외부지배구조(Big4회계법인감사여부, 시장지배력, 금융기관차입비율 및 외국인지분율)는 기업가치와 유의적인 관련성이 있는 것으로 나타났다. 둘째, 최대주주지분율, 대형회계법인감사여부, 시장지배력, 금융기관차입비율, 외국인지분율 등의 내부 및 외부지배구조와 가치관련성은 강소기업과 일반기업 간에 유의적인 차이가 있는 것으로 나타났다. 특히, 강소기업의 경우에는 최대주주지분율이 높을 수록 일반기업에 비해 기업가치가 증가하는 것으로 파악되어 최대주주지분율이 낮을수록 기업지배구조가 우수한 것이라는 전통적인 견해와는 상이한 연구결과가 나와 주목된다. 셋째, 강소기업의 내부 및 외부지배구조는 무형자산성 지출에 영향을 주고, 이를 통해 기업가치가 유의하게 증가하는 것으로 나타났다. 본 연구는 강소기업의 지배구조와 가치관련성을 심층적으로 분석한 최초의 연구라는 점에서 큰 의미가 있다. 내부지배구조 변수뿐만 아니라 외부지배구조 변수를 동시에 고려하여 지배구조가 기업가치에 미치는 영향을 포괄적으로 분석하였다. 특히, 강소기업과 일반기업을 비교 분석함으로써 기업지배구조 관련 규제 및 제도가 강소기업과 일반기업 간에 차별적으로 이루어질 필요가 있다는 시사점을 제공하고 있다. 또한 강소기업의 내부 및 외부 지배구조가 우수할수록 무형자산성 지출이 확대됨으로써 기업가치가 증가한다는 본 연구결과를 통해 강소기업의 내부 및 외부 지배구조와 무형자산성 지출의 중요성을 새롭게 확인할 수 있다는 점에서 시사하는 바가 크다. This study investigated the value relevance of intangible expenditures according to internal and external corporate governance of Korean hidden champion firms. First, this paper analyzed the value relevance of internal and external corporate governance for all KOSDAQ market listed manufacturing and IT firms. Then, this study analyzed differences in the value relevance of internal and external corporate governance between hidden champion firms and control firms selected by the propensity score matching(PSM) method corresponding to the hidden champion firms. Hidden champion samples were selected from the annual list of hidden champion firms announced by the Korea Exchange. Further, this study performed in-depth analysis on whether intangible expenditures according to internal and external corporate governance of hidden champion firms significantly increased their firm values using the two-stage least squares(2SLS) method. The results of the study are as follows: First of all, the internal corporate governance variables(number of the board of directors, proportion of outside directors among the board of directors and the largest shareholders’ holdings) as well as the external corporate governance variables(whether being audited by Big4 auditors, market dominance, borrowing ratio from financial institutions and foreign investor ownership) of KOSDAQ market listed manufacturing and IT firms were significantly associated with the firm values. Moreover, the value relevance of internal and external corporate governance variables were found to be significantly different between hidden champion firms and control firms. In particular, the firm values of hidden champion firms significantly increased compared to control firms when the largest shareholders’ holdings were higher. The result shows contrasting aspect to the traditional point of view that maintaining a relatively lower level of the largest shareholders’ holdings results in better corporate governance. Lastly, the internal and external corporate governance of hidden champion firms affected intangible asset expenditures, and the firm values were increased significantly. This study contributes that it is the first study to analyze the association between value relevance and corporate governance of hidden champion firms. In addition, this study comprehensively analyzed the value relevance and corporate governance by considering the external corporate governance variables as well as the internal corporate governance variables in research models. Specifically, the results of comparative analysis between hidden champion firms and control firms suggest that regulations and systems related to corporate governance need to be differentiated between hidden champion firms and other firms. Further, the results of this study confirms the practical importance of intangible expenditures in addition to the internal and external corporate governance, as high level of internal and external corporate governance increases firm values through the expansion of intangible expenditures.

Innovative Ideas for a College English Program : Voices from 71 International Faculty Members

한상호(Sang-Ho Han) 한국영어어문교육학회 2015 영어어문교육 Vol.21 No.2

The purpose of this study is to examine international faculty’s perceptions on an English education program of a university in order to discover innovative ideas for curricular innovation. Seventy-one international faculty of different educational and cultural backgrounds were asked to share their views on the following open-ended questions: obstacles to teaching English, perception of their students’ level of motivation and communicative abilities, the best way of improving students' English communicative skills, suggestions for regular courses and extracurricular programs, and suggestions for infrastructure and academic support structure. As a result of the survey, it was found that the three most difficult obstacles to enhancing communicative abilities of students were the mixed-level of students in the class, lack of technological support, and raising students’ motivation toward English. The three most critical areas for educational innovation were general English education, extracurricular programs, and major English programs. Finally, as a result of the international faculty’s investment, a thorough list of effective courses and class activities are suggested along with the list of items to be considered for innovation in infrastructure and academic support structure.
