This paper examines how APEC has transformed itself into an international forum for the vision of regional integration. It aims to quantify the documentation produced by the international organization and provide quantifiable evidence that aligns with prior knowledge rather than relying solely on intuition. For this purpose, I use various text mining techniques to extract multi-dimensional features from the text of APEC Leaders' Declarations from 1993 to 2023. In terms of interest and expectations for APEC as a forum, it is found that members have experienced two major peaks and troughs over the last three decades. It is found that the change point coincides with the Asian financial crisis of 1997 and the tensions between the United States and China since 2017. To explore more various aspects of economic integration in the Asia-Pacific region, this study also considers how consistently APEC has been an international forum for addressing issues, which members are active, and how members have clustered based on their views of APEC.

각기 다른 특성을 가진 학습자 모두가 의미 있는 배움에 다다르기 위해서는 교육과정-수업-평가가 일체화되야 한다. 본 연구에서는 일체화를 내용적 적합성, 행위자 합치성, 제도적 연계성 등의 세 가지 측면으로 분류하고, 각각의 관점에서 일반학교 특수학급의 일체화 실태를 관련 연구를 통해 살펴보았다. 연구 결과, 내용적 적합성 측면에서는 특수교육 대상 학생에 대한 교육과정 조정-교수적 수정-평가 조정이 개별화 교수가 이루어지는 과목 외에는 잘 이루어지지 않았다. 행위자 합치성 측면에서는 일반교사와 특수교사의 역할의 모호성으로 인해 교육과정 조정자, 수업자, 평가자 등이 일치하지 못하거나 최소한의 협의조차 이루지 못하였다. 제도적 연계성 면에서는 개별화 교수가 이루어지는 과목 외에는 교육과정 조정, 교수적 수정, 평가 조정의 권한 관계와 역할 주체가 불분명했다. 이러한 문제점을 논의하고 개선하기 위한 대안으로 개별화 교육에 대한 인식 제고, 협의체 의무화, 제도적 정비 등을 제언하였다.

Objective: The purpose of this study was to learn from Korean female defectors about their views of child-rearing experiences in South Korea. This study explored how 7 North Korean female defectors with young children developed child-rearing microideologies that acknowledge both North Korean cultural ideology and South Korean cultural ideology. Methods: To examine North Korean female defectors' child-rearing experiences, indepth interviews with 7 North Korean female defectors with young children were conducted. Results: Four theme clusters, 11 themes, and 47 meanings were found from a phenomenological analysis with indepth interview data. Based on the themes, three types of child-rearing microideologies were identified: (1) separation,(2) assimilation, and (3) integration. Each type of child-rearing microideology can be understood with a meaningful phrase "there is no choice", "nevertheless" and "because I came here to be better," respectively. Conclusion/Implications: This study provides knowledge on the individual-specified child-rearing strategy of North Korean female defectors with young children and suggests the necessity of diverse policy proposals based on the child-rearing microideology types.

In finance literature, stock liquidity showing how stocks can be cashed out in the market has received rich attentions from both academicians and practitioners. The reasons are plenty. First, it is known that stock liquidity affects significantly asset pricing. Second, macroeconomic announcements influence liquidity in the stock market. Therefore, stock liquidity itself affects investors' decision and managers' decision as well. Though there exist a great deal of literature about stock liquidity in finance literature, it is quite clear that there are no studies attempting to investigate the stock liquidity issue as one of decision making problems. In finance literature, most of stock liquidity studies had dealt with limited views such as how much it influences stock price, which variables are associated with describing the stock liquidity significantly, etc. However, this paper posits that stock liquidity issue may become a serious decision-making problem, and then be handled by using data mining techniques to estimate its future extent with statistical validity. In this sense, we collected financial data set from a number of manufacturing companies listed in KRX (Korea Exchange) during the period of 2010 to 2013. The reason why we selected dataset from 2010 was to avoid the after-shocks of financial crisis that occurred in 2008. We used Fn-GuidPro system to gather total 5,700 financial data set. Stock liquidity measure was computed by the procedures proposed by Amihud (2002) which is known to show best metrics for showing relationship with daily return. We applied five data mining techniques (or classifiers) such as Bayesian network, support vector machine (SVM), decision tree, neural network, and ensemble method. Bayesian networks include GBN (General Bayesian Network), NBN (Naive BN), TAN (Tree Augmented NBN). Decision tree uses CART and C4.5. Regression result was used as a benchmarking performance. Ensemble method uses two types-integration of two classifiers, and three classifiers. Ensemble method is based on voting for the sake of integrating classifiers. Among the single classifiers, CART showed best performance with 48.2%, compared with 37.18% by regression. Among the ensemble methods, the result from integrating TAN, CART, and SVM was best with 49.25%. Through the additional analysis in individual industries, those relatively stabilized industries like electronic appliances, wholesale & retailing, woods, leather-bags-shoes showed better performance over 50%.
