최근 코로나 바이러스로 인한 팬데믹이 장기화 되었고 이는 개인의 정신건강에도 많은 악영향을 미치고 있다. 이에 따른 코로나 우울감 해소 방안으로 '감정일기 애플리케이션'을 제안하며 감정 분석을 위해 2차원 좌표계를 사용한다. 이 애플리케이션에서는 사용자가 입력한 좌표값의 평균으로 콘텐츠를 추천하는데, 평균 좌표값이 획일화되어 한 가지 범주에 고착되는 문제가 있다. 이를 해결하고자 본 논문에서는 콘텐츠 평가 변수 및 사용자 성향 변수를 이용하여 평균 좌표값에 변화를 주었다. 이를 통해 사용자에게 보다 적합한 콘텐츠 추천을 기대한다.

본 논문은 기능성 실버 게임의 플레이 과정에서 사용자의 인지적 반응을 코드화 하고, 실증적 방법을 통해 인지처리과정을 분석하고, 패턴화 시키는데 목적을 둔다. 뉴웰의 MHP(Model Human Process)이론을 평가를 위한 모델로 삼고, 평가 방법 설계를 위해 Schneier와 Mehal의 정량적 변수와 정성적 변수 이론을 사용한다. 실험은 실증적 평가방법 중 특정 부분에 대한 정밀한 평가를 주로 하는 실험실 평가로 전문가 집단을 통한 예비실험을 실시한다. 인지기능 향상을 위한 기능성 실버게임의 인지패턴 표준화를 위한 연구는 급속하게 고령화 사회로 변화되고 있는 현 시장에 새로운 문화콘텐츠 개발의 중요한 지표로 활용되리라 기대한다.

It is not easy to predict the return on investment in the content business, and there is no index to evaluate cast & crew. The absolute number of TV ratings is steadily declining, but there is no substitute index yet. In this study, we tried to predict the relative popularity of the drama by designing the relative superiority of the individual drama viewership as the response variable and designing the relative superiority of the drama participants as the explanatory variables. We used various machine learning algorithms and added explanatory variables that were found to be useful in previous studies. As a result, with properly combined explanatory variables, a high prediction accuracy of 84% is obtained. In this study, we intend to promote the investment efficiency of the entire contents industry by predicting the relative popularity of the contents.

The purpose of this paper is to capture risk profiles of smaller-sized Korean firms $vis-{\grave{a}}-vis$ larger-sized firms during the Asian financial crisis. For this purpose, risk profiles are provided by estimating expected default risks and by tracking how these have changed during this period with respect to their magnitude, volatility, and sensitivity measures. Methodology used in this study employs the Black-Scholes-Merton model for producing estimates of default risks. And the conventional trans-log function is utilized for obtaining sensitivity measures of the estimated default risks. According to empirical evidence obtained here, it is revealed that contractions of corporate loans associated with IMF austerity policy was the main factor responsible for the drastic change in the default risk profile of Korean firms after occurrence of the Asian financial crisis.

This study aims to evaluate the efficiency of superior appraisal corporations using DEA(Data Envelopment Analysis). DEA is known as a method for evaluating relative efficiency of organizations with multiple inputs and outputs. We used CCR-O and BCC-O DEA models to evaluate relative efficiency of superior appraisal corporations. Input variable is number of appraisers, output variables are total sales and net income. Total of 13 appraisal corporations in Korea were selected for this study, and the data were collected from financial reports for 2008 fiscal year. The result of this study is summarized as follows. First, the average of superior appraisal corporation's technical efficiency score is about 88.3% by applying CCR-O model. Second, the average of superior appraisal corporation's pure technical efficiency score is about 90% and scale efficiency score is about 98.2% by applying BCC-O model. According to the result of DEA, the cause of inefficiency is pure technical efficiency.

이 연구는 일본식 배수공이 설치된 제방의 침투 흐름을 비정상 상태로 SEEP/W 모형을 사용하여 해석하고 모형의 적용성을 평가하기 위해 수행하였다. 수치모형의 적용성 평가를 위해 비정상 상태로 제방 침투에 대한 수리모형실험을 수행하였다. 제체 재료는 경상북도 구미시에 위치한 해평천의 제방 건설 현장의 재료를 사용하였고 일본식배수공은 굵은 골재와 부직포를 사용하여 실험실에 제방 축소 모형을 수조 내부에 제작하였다. 모형제방은 제방축조 방법과 유사하게 다짐을 하기 위해 흙을 쌓으면서 0.20 m 높이마다 다짐을 실시하였다. 다짐방법은 고무망치를 이용한 층다짐을 하였다. 제방 제외지에 0.55 cm/min의 속도로 수위를 증가하여 15분 간격으로 각 0.3 m, 0.4 m, 0.5 m 수위에 따른 비정상 상태의 위압계 측정을 수행하였다. SEEP/W 모형의 매개변수는 투수계수와 입도분포도, 불포화 함수특성곡선(값을 산정하기 어려움)이 있으며, 각 매개변수에 대한 민감도 분석을 수행하였다. SEEP/W 모형의 모의 결과는 수리모형실험 결과와 비교적 잘 일치함을 알 수 있었다.

Recently, although the interest in transfer and transactions of intangible assets increases, there is no valuation model to objectively assess market value of knowledge and information contents such as electronic databases and the necessity of researches associated is brought up. Therefore, the present study proposes valuation models so as to utilize as objective reference information in the contents market of intangible assets, by assessing the market value of science and technology information contents including patents, academic papers and reports. First, we look into application methods of calculating cash flows by content types out of key variables which has been applied to the present technology valuation, and in case of patents we propose valuation methods based on concepts which are applied in the present technology valuation. Next, in case of both papers and reports, in order to reflect the characteristics of these contents we newly propose qualitative valuation methods which are adjustable based on both technology innovation and market demands indices while estimating the economic life cycle of the technology, and also present the input cost-based calculation method as the calculation method of cash flows. Throughout the study, we could establish frameworks by technology fields and business models applicable such as copyright licensing, transactions of individual science and technology information contents, and expect that more objective and reasonable assessment of content values is accessible.

The purpose of this study is to derive the suggestion of satisfaction of e-book services on the basis of the recent literature on quality assessment for e-service which have been mainly studied on library realm. For this purpose, This study added post-management service which is applicable to measure satisfaction of e-book services based on E-S-Qual and Libqual. We expand our scope of service to using of e-book content and services for individual customers, and analyzed the relationship between satisfaction with the system, the content, the after-sale service. On this foundation, existing e-book service companies can offer their services more efficiently, thereby making the e-book content more diverse, along with developing specialized e-book service to increasing their customer's satisfaction. In addition, the latest and diversity is important as well. Moreover, performing rapid post-management services after the sale of the product or service, can be important variables for customer satisfaction. Therefore, not only the system and content, providing required level post-management services by customers can satisfy the existing customers and create new customers.
