This study investigates the critical success factors for the promotion of IT industry in region and suggests some directions for operations strategy of them. This study based on the critical success factors, and we suggest followings:(1) start-ups support, (2) technology support, (3) management support, (4) law/institutional support. We suggested the strategy which based on critical success factors for successful operations of IT industry. This strategy suggested by AHP(Analytic Hierarchy Process) results and was evaluated by the three groups(IT firms, local government official worker, professor) which have an influence on IT policy. We suggested the priority of policy by AHP technique for successful development of IT industry. As a results, centralization of supporting facilities was perceived as the most important policy by three groups(IT firms, local government official worker, professor). This research contributes to assist planners and policy-makers in supporting IT industry by providing useful information about the suggested strategy, and by suggesting the effective means to assist the IT industry. Also, results of our research will be suggested as a priority of developing policy to assist successful IT industry.

SWOT/AHP에 의한 한·독 히든챔피언의 경쟁력에 관한 연구

이상석 한국국제경영관리학회 2017 국제경영리뷰 Vol.21 No.3

본 연구는 한독 히든챔피언 간의 SWOT요인 중요도를 비교하고, 이를 바탕으로 하는 경쟁력을 측정하기 위한 계량적 모형을 개발하여 한국과 독일 간의 경쟁력을 비교함으로서 경영 학적 함의를 도출하고자 하였다. 이에 한국과 독일의 히든챔피언을 대상으로 실증조사를 통해 AHP기법을 적용하여 중요도 및 경쟁력 지수를 산출하였다. 연구결과 첫째, 중요도 분석에서 SWOT(강점, 약점, 기회, 위협)의 중요도에는 국가 간에 약간의 차이는 있었으나 순위에는 변동이 없는 것으로 평가되어 SWOT에 대한 국가별 CEO의 인식은 비슷하다는 것을 알 수 있 었다. SWOT의 세부요인 중에서는 강점의 기술적 역량, 약점의 해외시장지식 결여, 위협의 시장 불확실성이 통계적으로 유의한 차이가 있는 것으로 나타났다. 기회에 대한 모든 세부요인에 대해서는 통계적으로 유의하지 않은 것으로 나타나 중요도에 대한 인식에 차이가 없는 것 으로 분석되었다. 둘째, 경쟁력 분석에서는 강점의 경쟁력은 두 나라 간에 비슷하게 경쟁력 지수가 산출되었으나 다른 요인에 대해서는 경쟁력 차이가 있다는 것을 알 수 있었다. 즉, 강점에 대한 세부 요인에 대해서는 경쟁력에 차이가 없었으나 약점의 해외사업경험부족, 기회의 정부지원정책 활용도, 위협의 정부의 전주기적 지원정책 결여에 대한 경쟁력에는 차이가 존재하는 것으로 분석되었다. 히든챔피언의 강점으로 분류된 기업가정신, CEO의 사업경험, 기술적 역량, 시장 지향성, 마케팅 역량, 고객관계 구축역량 등에 대한 경쟁력 지수는 두 국가 간에 차이가 없는 것으로 분석됨으로서 히든챔피언에 대한 기존 연구결과와 유사성을 가지고 있었다. This study reviews preceding research for detailed factors to measure competitiveness for Korea and Germany Hidden Champions and classifies specific factors into internal ones(strengths, weaknesses) and external ones(opportunities and threats). It also sets hierarchical model to draw up a survey, distributes the survey to CEO of Hidden Champions and then examines consistency ratio for AHP logic. One hundred-one copies(61 in Korea; 40 in Germany) of survey whose reliability on responses is secured through examining the consistency ratio are evaluated with their relative weight by using AHP. The weights of SWOT factors of hidden champion have been identified and the differences of weight between two countries. The technology capability of strength, the lack of knowledge on overseas market of weakness and the market uncertainty of thereat have statistically differences between two groups. Based on their results, Competitiveness Index for Korea and Germany Hidden Champions are measured. Competitiveness Index results show that external factors are statistically differences in government support policies availability of opportunities, lack of government periodical policy support of threats. And internal factors are significant differences in lack of global business experiences of weakness. In case of Korea, this result means that there are should be stand for the lack of global business experiences with governmental policy support and aggressive strategies without governmental support cannot help but be adopted in a global competition getting fiercer every day. And then, there are statistically no differences the detailed factors in strengths between two countries.

We are living in an age of affluences. The significances of tourism as a social phenomenon have been increasing in these days. Geneally speaking, most of the geographical approaches to the tourism and its related concepts are destitute of the epistemological and methodological aspects, which are indispensible to the rational explanations in an academic discipline. This study is purposed to understand how we are able to explain the tourism behaviours with respect to some of the tourism motivations. From the humanistic viewpoints the tourist resort as the tourism object, is the place towards which subjective meanings of intention are directed. A tourist would make tour travel in order to grasp such meanings of the places, and the sense of place would motivate tour travel. In the place where we are living, there have been carved by some deep meanings of our lived experiences, and this meanings of each subjective life world is represented in the forms of public symbols, fields of care, etc. The toruism object as a centred point of intended meanings which are constituted through their own living experiences, must be understood in the context of their own subjectivities. These meanings are usually reflected in the concepts of geopiety and topophilia, the senses given to some places where we have any attachment or piety. If there were no subjective meaning related with it, there could not exist any objectivity. The historical-cultural phenomena such as tourims behaviour, economic activity, day-by-day living, interpersonal contacts, and so on, are a part of fields related with complex human beings. As such, so there are subjective intentions in the deep layer of these objects, and there are implicit subjectivities behind any explicit onjectivity as scientific rationale with tourism behaviour. As Tuan, Y. F. has noted, to see is to know, to sense, to understand, and to catch the meanings of the humanized place, where the involved human beings had carved their meanings of that time. It is the meaning of place that we must capture in order to understand what make the tourists behave in a certain way.

The in-process detection of the state of cutting tool is one of the most important technical problem in Intelligent Machining System. This paper presents a method of detecting the state of cutting tool in turning process by using Artificial Neural Network. In order to sense the state of cutting tool, the sensor fusion of an acoustic emission sensor and a force sensor is applied in this paper. It is shown that AErms and three directional dynamic mean cutting forces are sensitive to the tool wear. Therefore the six pattern features that is, the four sensory signal features and two cutting conditions are selected for the monitoring system with Artificial Neural Network. The proposed monitoring system shows a good recognition rate for the different cutting conditions.
