안이수(Lee-Su Ahn) 한국콘텐츠학회 2018 한국콘텐츠학회논문지 Vol.18 No.11

본 연구는 정치인의 종합적 이미지에 대하여 유권자가 가지고 있는 가치와 태도를 밝혀내고 유권자가 갖는 주관성의 구조를 심층적으로 알아보았다. 이러한 작업을 통하여 유권자의 정치적 행동에 미치는 영향력을 설명하는 것이 연구의 목적이다. 본 연구에서는 이재명 경기도지사 인식에 대한 3개의 유형이 도출되었는데, 제1유형(N=4) : 뚜렷한 원칙과 추진력 있는 개혁가, 제2유형[(N=12) : 실행력 있는 실용적 정책가, 제3유형(N=4) : 정치적 야망을 달성하고자 하는 포퓰리스트로 분류되었다. 제1유형은 이재명 경기도지사는 기득권의 장벽을 허물 수 있는 적임자라는 의견을 보였고, 제2유형은 성남시장 재임 중에 보인 행정능력으로 유권자 피부에 와 닿는 실용적 정책을 펼칠 것으로 기대를 가지고 있었으며, 제3유형은 현실성이 떨어지는 주장으로 자신의 정책과 태도만 부각시켜 인지도를 높이고 인기만 끌려는 태도에 우려를 표시했다. This research studies voter’s value and attitude reflected by the politician’s overall image and scrutinizes the separate structures of the voters’ subjectivity on the matter. Objective of the research is to explain the influence that exercises on voters’ political actions through this procedure. On this research, there were 32 Q samples that are selected, and they were categorized by a pool of 20 people. Result showed total of 3 different categories of cognition patterns towards Gyeonggi-do Governor Lee Jae Myeong. Of the 3 categories, category 1 (N=4) was a reformer with apparent principles and initiatives, category 2 (N=12) was an efficient tactician with executive ability, and the last category 3 (N=4) was a populist that strives to achieve his political ambition. Opinion of the samples in the first category was that Governor Lee is the right guy for demolishing the barrier between vested class and the non-vesting in the society. Voters in the second category showed expectation for Governor Lee’s executive policies that satisfy the voters, given his abilities proven while he was in mayor’s office for Seongnam city. People in the pool of category 3 worried that Governor Lee is busy increasing his approval rating and popularity by asserting unrealistic opinions and impractical policies.

This paper presents form-finding of Tensegrity structures by using Force method. The Force method is generalized to all types of skeletal structures, such as rigid-jointed frames, pin-jointed planar trusses and ball-jointed space trusses. This method has easier basic concept, which is based on equilibrium equation, than Finite Element Method. In addition, this method is appealing to engineers because the properties of members of structures most often depend on the member force than joint displacement. Therefore, this study applies to analyze about form-finding of Tensegrity structures by using Force method’s merit.

Sonar system detects target informations using multiple sensors, and fuses the informations to get the more trustworthy target information than that of each sensor. For improving the performance of fusion tracking system, it is exactly analyzed the probabilistic characteristics of the estimated information of each sensor. In this paper we analyze the bearing estimation error according to beamwidth of line array sensor and cylindrical sensor, and then propose a bearing tracking filter taking into account it. Cylindrical array represents equal characteristics of bearing error, but line array sensor represents different characteristics because of different beam width to steered beam direction. And we verify that the tracking and fusion performance is improved by using the calculated probabilistic covariance of bearing estimation error.

There are only a handful number of research conducted on pattern analysis of corporate distress as compared with research for bankruptcy prediction. The few that exists mainly focus on audited firms because financial data collection is easier for these firms. But in reality, corporate financial distress is a far more common and critical phenomenon for non-audited firms which are mainly comprised of small and medium sized firms. The purpose of this paper is to classify non-audited firms under distress according to their financial ratio using data mining; Self-Organizing Map (SOM). SOM is a type of artificial neural network that is trained using unsupervised learning to produce a lower dimensional discretized representation of the input space of the training samples, called a map. SOM is different from other artificial neural networks as it applies competitive learning as opposed to error-correction learning such as backpropagation with gradient descent, and in the sense that it uses a neighborhood function to preserve the topological properties of the input space. It is one of the popular and successful clustering algorithm. In this study, we classify types of financial distress firms, specially, non-audited firms. In the empirical test, we collect 10 financial ratios of 100 non-audited firms under distress in 2004 for the previous two years (2002 and 2003). Using these financial ratios and the SOM algorithm, five distinct patterns were distinguished. In pattern 1, financial distress was very serious in almost all financial ratios. 12% of the firms are included in these patterns. In pattern 2, financial distress was weak in almost financial ratios. 14% of the firms are included in pattern 2. In pattern 3, growth ratio was the worst among all patterns. It is speculated that the firms of this pattern may be under distress due to severe competition in their industries. Approximately 30% of the firms fell into this group. In pattern 4, the growth ratio was higher than any other pattern but the cash ratio and profitability ratio were not at the level of the growth ratio. It is concluded that the firms of this pattern were under distress in pursuit of expanding their business. About 25% of the firms were in this pattern. Last, pattern 5 encompassed very solvent firms. Perhaps firms of this pattern were distressed due to a bad short-term strategic decision or due to problems with the enterpriser of the firms. Approximately 18% of the firms were under this pattern. This study has the academic and empirical contribution. In the perspectives of the academic contribution, non-audited companies that tend to be easily bankrupt and have the unstructured or easily manipulated financial data are classified by the data mining technology (Self-Organizing Map) rather than big sized audited firms that have the well prepared and reliable financial data. In the perspectives of the empirical one, even though the financial data of the non-audited firms are conducted to analyze, it is useful for find out the first order symptom of financial distress, which makes us to forecast the prediction of bankruptcy of the firms and to manage the early warning and alert signal. These are the academic and empirical contribution of this study. The limitation of this research is to analyze only 100 corporates due to the difficulty of collecting the financial data of the non-audited firms, which make us to be hard to proceed to the analysis by the category or size difference. Also, non-financial qualitative data is crucial for the analysis of bankruptcy. Thus, the non-financial qualitative factor is taken into account for the next study. This study sheds some light on the non-audited small and medium sized firms’ distress prediction in the future.

감초는 배당체인 주요성분이 발효를 통해 무배당체로 전환이 될 경우 생리활성을 증가시켜 건강기능식품으로의 활용가능성을 높일 수 있을 것으로 사료된다. 따라서 본 연구에서는 감초추출물에 Lactobacillus acidophilus KCCM 32820를 고농도로 배양하며 glycyrrhizin함량의 관찰 등을 통해 감초추출물 발효액의 제조 가능성을 검토하였다. 감초 추출물은 접종량 106CFU/mL의 발효에서는 6일 후 pH의 변화가 -0.32였으나, 접종량 107CFU/mL과 108 CFU/mL 수준에서 pH와 glycyrrhizin 의 함량은 발효 2일까지 급속도로 떨어진 후 완만한 변화하여, 발효 6일 후의 감초추출물 내 glycyrrhizin 의 잔류농도는 27.5 mg/100mL 및 20.8mg/ 100mL 였으며 이용률은 71.8% 및 78.6% 였다. 따라서 감초 추출물의 발효는 초기 접종량을 107CFU/mL 이상의 고농도로 접종하여 발효시키는 것이 효과적이었다. Naalginate로 고정화한 균을 접종한 경우가 비고정화균 의 배양에 비해서는 pH와 glycyrrhizin함량의 저하 속도가 빨랐다. 향후 발효생성물의 정량과 함께 이들의 기능성에 대한 추가적인 연구 결과를 통해 감초추출물의 효능 증대에 대한 결론을 얻을 수 있을 것이다. Aglycon in licorice converted from glycosides by fermentation has been implicated to improved physiological activity, this study was carried out to determine the aglycon production in the cultured licorice-extract broth by Lactobacillus acidophilus KCCM 32820. According to inoculum size, pH was decreased -0.32 after 6 days at 106CFU/mL, pH and contents of the glycyrrhizin in culture broth were rapidly decreased after 2 days at 107CFU/mL and 108CFU/mL, the concentration of glycyrrhizin after 6 days were determined 27.5 mg/100mL and 20.8 mg/100mL, the utilization rates were 71.8%, 78.6%, respectively. Initial inoculum size should be above 107CFU/mL on the fermentation of licorice extracts, and immobilized L. acidophilus KCCM 32820 was faster decrease than free cell on the fermentation. The metabolites of fermented licorice extracts can be verified the improvement in efficacy of physiological functions, further research need to do.
