기업의 전시회 참가가치와 선택속성이 전시 참가활동에 미치는 영향
임택(Lim, Taek),배순근(Bae, Soon-Kuen),김태칠(Kim, Tae-Chil),김봉석(Kim, Bong-Seok) 한국전시산업융합연구원 2013 한국과학예술융합학회 Vol.14 No.-
본 연구는 기업들의 전시회 참가에 대한 참가가치를 규명하고자 하는 데 있다. 첫째, 기업들의 전시회 참가가치를 규명해 보고자 하였다. 본 연구를 통하여 전시회에 참가하는 기업들이 갖고 있는 가치 기준과 이에 따른 일련의 영향 과정에 대한 분석을 실시하였다. 둘째, 기업들의 전시회 참가가치가 전시회 선택속성 및 전시마케팅 활동에 미치는 영향을 파악하고자 시도하였다. 전시회에 참여하는 기업들의 가치 기준이 상이한 상황에서 각각 기업들이 어떠한 판단에 따라 전시회를 선정하고 마케팅 전략을 세워 활동을 하는 지에 대한 영향 관계를 분석하였다. 셋째, 전시회 선택속성과 전시 마케팅 활동이 전시 참가업체의 재참가 활동에 어떠한 영향을 미치는지 분석하고자 하였다. 본 연구를 통하여 기업의 전시회 참가에 대한 가치판단과 선택속성이 각각 전시 참가 활동과 재참가 의사에 미치는 영향을 좀 더 세밀히 규명하고자 하였다. 또한 기업들이 제품 마케팅 활동 수단으로 전시회를 좀 더 적극적으로 활용하도록 함으로써 궁극적으로는 전시회를 규모면에서는 대형화 시키고, 내용면에서는 국제화를 도모하여 우리나라 전시산업 발전에 도움이 될 수 있는 시사점을 제시하였다. The purpose of this study lies in clarifying the differences of the levels of perception upon the importance of the values of exhibition participation. Firstly, this study clarifies exhibitors’ values of exhibition participation. This is to analyse general value standards of participating companies and how it affects their decision process of exhibition participation. Secondly, this study analyses how exhibitors" values of participation affect their exhibition selection attributes and exhibition marketing activities. Under the circumstance in which exhibitors" standards of value are different from one another, this study analyses core driving factors of exhibitors" judgement for selecting exhibitions to participate in and perform strategic marketing activities. Thirdly, this study also analyses how exhibitors" exhibition selection attributes and their exhibition marketing activities influence on their final results and re-participation. Lastly, through this study, it is intended to convey strategic policy implications based upon in-depth analysis of the whole process of companies" participation. The development of exhibition industry depends much on the number of various exhibitors(corporate participants) and along with the purpose of this study, this ultimately leads to the point that through the in-depth study regarding participants" standards of participating value, we need to come up with solutions for fulfilling their values of participation and find how the values affect participants" effective planning for exhibition marketing activities and re-participation activities in terms of the original purpose of exhibition as an integrated corporate marketing vehicle.

ARMA-PL : Tacking Nested Periods and Linear Trend Time Series Data
서정열,이세재,오현승,구자활,임택,조진형,Suh, Jung-Yul,Lee, Sae-Jae,Oh, Hyun-Seung,Koo, Ja-Hwal,Lim, Taek,Cho, Jin-Hyung Society of Korea Industrial and System Engineering 2010 한국산업경영시스템학회지 Vol.33 No.2
시계열데이터는 ARMA 분석에 적합지 않은 요소를 내재하고 있는 경우가 있다. 특히 선형성과 주기성을 가진 요소가 확률적인 분포와 자주 혼재되어 있다. 이 논문에서는 이런 선형적 주기적 요소를 찾아내고 분석하는 방법을 제시한다. 특히 주기적 요소는 여러 주기가 층층이 겹쳐져서 나타난다. 주기 간에는 서로 일정 정수비율을 유지하며, 한 주거 안에 다른 주기가 내포되어 있는 경우(nested periods)가 많다. 시간규모(time-scale)개념을 도입하여 이러한 주기적 요소를 개념적으로 정립하고자 했다. 선형적 요소와 주기적 요소가 제거된 후 추출된 데이터는 MA-approximation이라는 방법을 사용하여 가장 데이터에 근접한 ARMA 모텔을 찾아낸다. 마지막으로 선형적 주기적 요소와 ARMA 추정결과를 종합하여 control boundary를 결정하는 방법을 제시한다.

Engineering valuation is a specialized discipline requiring expert knowledge and judgment, which scientifically estimates the economic value of industrial properties. By industrial properties, we mean engineering structures such as mines, factories, buildings, machines, and other industrial facilities as well as facilities of public enterprises. Particular industrial properties can have longer economic life if their performance is excellent and they are still suitable for current manufacturing needs. If not, its economic life will be shorter. As speed of technological progress becomes rapid, life-cycle and development period of a product is becoming shorter. In an industry characterized by rapid development of technology, industrial properties can become obsolescent faster. Even if they are in good working order, they could be no longer suitable for manufacturing new products based on radically different technology. In our research, we apply engineering approach to estimating functional economic life by factoring in technological obsolescence in such an industry.

The purpose of this study is to analyze the economic evaluation of the exhibition & convention center using a cost-benefit analysis. This study reviews the function and role of exhibition & convention center and finds its attributes as the public goods and infrastructure. For a case study, KINTEX is analyzed empirically for estimating the economic value on the basis of ex-post construction and operating data. As a result of a cost-benefit analysis on KINTEX, B/C ratio is 1.39, NPV is 638 billion won and IRR is 10.87%. The difference between this analysis and precedent study is that this analysis`s benefit items and scale are extended. Accordingly for the more useful cost-benefit analysis on exhibition & convention center, the exact benefit assessment should be improved.

자기상관이 있는 장치 공정에서 EWMA와 Shewhart 관리도와의 모니터링 효율성 비교 분석
조진형(Jin-Hyung Cho),오현승(Hyun-Seung Oh),이세재(Sae-Jae Lee),정수일(Su-il Jung),임택(Taek Lim),백선상(Seong-seon Baek),김병극(Byung-Keug Ki) 한국산업경영시스템학회 2012 한국산업경영시스템학회지 Vol.35 No.4
When monitoring an instrumental process, one often collects a host of data such as characteristic signals sent by a sensor in short time intervals. Characteristic data of short time intervals tend to be autocorrelated. In the instrumental processes often the practice of adjusting the setting value simply based on the previous one, so-called ‘adjacent point operation’, becomes more critical, since in the short run the deviations are harder to detect and in the long run they have amplified consequences. Stochastic modelling using ARIMA or AR models are not readily usable here. Due to the difficulty of dealing with autocorrelated data conventional practice is resorting to choosing the time interval where autocorrelation is weak enough then to using I-MR control chart to judge the process stability. In the autocorrelated instrumental processes it appears that using the Shewhart chart and the time interval data where autocorrelation is relatively not existent turns out to be a rather convenient and very useful practice to determine the process stability. However in the autocorrelated instrumental processes we intend to show that one would presumably do better using the EWMA control chart rather than just using the Shewhart chart along with some arbitrarily intervalled data, since the former is more sensitive to shifts given appropriate weights.
