Since Modern Movement flexibility has been one of the most attractive words in architecture. However, "overprovision first, division later" has been the most prevailing design method for spatial flexibility, and many of buildings designed for flexible use are practically quite inflexible due to insufficient building systems or/and irresponsible planning. There have been two dominant strategies to achieve architectural flexibility: multi-functionality and polyvalence. These two approaches, which point contradictory directions, actually reflect the difficulty in providing a proper form of architectural flexibility. Multi-functionality can afford changeable environments with satisfying spatial conditions; however it lacks tolerance to accommodate other uses but intended functions by architects. Meanwhile, flexibility by a polyvalent form relies on the vague anticipation of user's various interpretations. In this study by looking up these two different standpoints and historical precedents flexibility in architecture is carefully scrutinized focused on the contradiction, and as an alternative for architectural flexibility contextual relations is proposed. Unlike both multi-functionality and polyvalence, which produce flexibility by changing its own properties, manipulating contextual relations infuses flexibility into space by changing the properties of a building, not of its individual room. By using this contextual relations method, a community-centered school in Manhattan, NY, which was in danger of being closed because of its academic failure, is represented as a flexible space.

In contemporary urban space, the identify is absent because of the object-oriented plans that ignore the context of urban space, and the ignorance of the regional characteristics and the historicity of places. Due to this reason, urban space lost its unique characteristics and becomes a mismatch with its surroundings. To solve these problems, the ideological trend of post-modernism emerged and new spatial paradigm rose based on the contextual concept to go with this trend. This contextual concept should be considered more importantly in the public space with discontinuous many and unspecified behavioral patterns. The components of space do not exist independently with individual identity. They should be considered based on a holistic view formed by the relations among elements and the establishment of those relations, and through this, correct identity can be established. Thus, this paper aims to analyze the context of spatial components through new contextual views on public spaces and study the expressional characteristics unveiled between these relations.

The purpose of this paper is to uncover whether and how contextual factors (information exchange, participation, trust in management, and training), relate to resistance to change. It also explores the mediating effect of perceived impact of change on the relations between contextual factors and resistance to change. This study is conducted in several manufacturing plants in food processing industry in Vietnam, which is implementing a top-down large-scale change - Lean transformation, adopting Total Productive Maintenance (TPM) program, to be specific. The findings suggest that all four contextual factors are negatively associated with resistance to change, in which training had the strongest impact. Also, the perceived change impact partially mediates the relationships between the four contextual factors and resistance to change. The practical implications of this paper are that employees who receive adequate, timely and useful information relating to change are less likely to show opposing behaviors towards change. Fostering trust in management among employees, and employee involvement in decision-making, also have a significant influence when addressing employee resistance to change. Employees who are well-trained, well-equipped with tools and knowledge about the change, are less likely to resist as they view the benefits of changes more significant than the risks.

Probabilistic Latent Semantic Analysis has many applications in information retrieval and filtering, natural language processing, machine learning from text, and in related areas. In this paper, we propose an algorithm using weighted Probabilistic Latent Semantic Analysis Model to find the contextual phrases and opinions from documents. The traditional keyword search is unable to find the semantic relations of phrases, Overcoming these obstacles requires the development of techniques for automatically classifying semantic relations of phrases. Through experiments, we show that the proposed algorithm works well to discover semantic relations of phrases and presents the semantic relations of phrases to the vector-space model. The proposed algorithm is able to perform a variety of analyses, including such as document classification, online reputation, and collaborative recommendation.

After-school activities of 817 7th grade children from Kwangju, Busan, and Kumi were studied to determine relations with (a) child, family and contextual variables (b) child's academic achievement and social development. Children were more likely to engage in extracurriculum activites and TV watching than other after-school activities. After-school activities were related to child's, parent's and contextual variables. Child's characteristics related to after-school activities were sex, impulse control, mastery and self-care. family's characteristics related to after-school activities were mother's employment, emotional support, control, monitoring and SES. Region and regional sagy were related to after-school activities. Some of after-school activities were related child's academic achievement and social development. Especially academic activites have a positive and powerful effects on child's academic achievement and social development.

Semantic interpretation of the relationship between noun compound (NC) elements has been a challenging issue due to the lack of contextual information, the unbounded number of combinations, and the absence of a universally accepted system for the categorization. The current models require a huge corpus of data to extract contextual information, which limits their usage in many situations. In this paper, a new semantic relations interpreter for NCs based on novel lightweight binary features is proposed. Some of the binary features used are novel. In addition, the interpreter uses a new feature selection method. By developing these new features and techniques, the proposed method removes the need for any huge corpuses. Implementing this method using a modular and plugin-based framework, and by training it using the largest and the most current fine-grained data set, shows that the accuracy is better than that of previously reported upon methods that utilize large corpuses. This improvement in accuracy and the provision of superior efficiency is achieved not only by improving the old features with such techniques as semantic scattering and sense collocation, but also by using various novel features and classifier max entropy. That the accuracy of the max entropy classifier is higher compared to that of other classifiers, such as a support vector machine, a Na$\ddot{i}$ve Bayes, and a decision tree, is also shown.

Despite a huge amount of foreign assistance and close economic guidance by international donors throughout the past decades, Zambia today still suffer from a high level of aid dependency and the absence of sustainable economic development. In this study, I investigate the factors that resulted in aid (and development) failure in Zambia, focusing on institutional/historical contexts. I propose that in Zambia, government has largely failed to implement (or even produce) effective economic policies that could lead to successful use of foreign assistance for long-term, sustainable development. In particular, I focus on the nature of state and politics in Zambia, and argue that failed politics is one of the main causes of development and aid failure in Zambia and highlight colonial legacies and other contextual/institutional factors to understand the nature of politics and state in Zambia. In particular, this paper proposes that the Zambian case demonstrates that foreign aid and donor influence could worsen the situation directly by simply providing wrong guidance and also by further weakening the state (and institutional) capacity of the recipient country.

유비쿼터스 환경에 기반한 시장, 즉 U-마켓에서는 고객이 제품을 구매함과 동시에 고객의 정보가 u-마켓 서버시스템에 저장되어 인터넷 쇼핑몰과 같이 다양한 분석과 활용이 가능하게 되었다. 물리적인 공간과 가상 공간이 결합된 유비쿼터스 기반의 시장 환경에서는 고객이 오프라인에서 다양한 매장을 방문하면서 쇼핑을 하게 되는데, 이때 여러 매장에 동일한 제품이 동시에 존재할 수 있으므로 매장의 위치, 매장 분위기, 제품의 품질이나 가격 등에 대한 고객의 선호도를 반영하여 고객 개개인에게 적절한 매장을 추천해야 할 필요성이 제기된다. 본 논문에서는 유비쿼터스 환경에 기반한 시장에서 고객의 쇼핑 상황을 고려하여 고객의 선호를 반영할 수 있는 매장 추천방법을 제안한다. 제안한 매장 추천방법은 협업 필터링과, Apriori 알고리즘을 기반으로 구성되어 있다. 온라인 쇼핑몰과는 다르게 U-마켓에서는 고객 개개인의 구매목록과 고객의 선호도를 반영한 매장 추천이 필요하며, 본 논문에서 제안하고 있는 매장 추천방법은 고객의 쇼핑경험을 극대화 하고 쇼핑 효율성을 제고시킬 뿐 아니라 장기적인 관점에서 매출증대를 통해 U-마켓 활성화에 기여할 수 있을 것으로 기대한다.

본 연구는 중학생의 또래괴롭힘 피해에 초점을 맞추어 개인수준에서 그 위험요인(사회적 위축)과 발달적 결과(우울)를 확인하고, 학급수준의 차별 효과를 살펴보기 위해 다층경로분석을 실시하였다. 구체적으로, 개인수준에서 중학생의 사회적 위축과 우울간의 관계에서 또래괴롭힘 피해의 매개효과를 확인하고, 나아가 또래괴롭힘 피해경험에 개인수준의 사회적 위축과 학급수준의 차별 간 층간 상호작용 효과가 발생하는지 확인하였다. 이를 위해 7개 중학교, 86학급에서 수집된 1,116명의 자기보고식 설문자료를 분석에 사용하였다. 그 결과, 개인수준에서 사회적 위축, 또래괴롭힘 피해, 우울 간의 부분매개효과가 유의하게 나타났고, 학급수준에서 차별은 또래괴롭힘 피해를 정적으로 예측하였다. 또한 사회적 위축과 차별의 층간 상호 작용 효과가 유의하게 나타나, 사회적으로 위축된 학생이 높은 수준의 차별이 발생하는 학급에 속할수록 또래괴롭힘 피해를 더 많이 경험한다는 것을 밝혔다. 이러한 결과는 개인수준의 취약성이 항상 또래괴롭힘 피해를 예측하는 것이 아니고, 맥락과 상호작용한다는 것을 보여주며, 결과적으로 또래괴롭힘 피해를 이해하기 위해 개인특성 뿐 아니라 학급의 맥락적 특성을 함께 고려해야 함을 강조한다. 마지막으로 연구 결과를 중심으로 효과적 개입전략에 대해 논의하였다.

본 연구는 최근 사회적인 문제가 되고 있는 직장 내 괴롭힘에 주목하여, 개인적 요인인 특성분노, 사회적 회피가 직장 내 괴롭힘을 예측하는 관계를 조직 분위기(의사소통 분위기, 사회적 분위기)가 조절하는지 살펴보았다. 이를 위해 서울 경기 지역 중소기업, 대기업 사무직 207명(남자: 115명, 여자: 92명)의 설문자료를 분석하였다. 위계적 회귀분석 결과, 특성분노는 조직의 사회적 분위기가 나쁠 때에만 남자의 직장 내 괴롭힘 피해를 정적으로 예측하였으며, 사회적 회피는 직장 내 의사소통 분위기가 좋을 때에만 남자의 직장 내 괴롭힘 피해를 높이는 것으로 나타났다. 여자의 경우, 이러한 조절효과는 나타나지 않았다. 특성분노는 의사소통 분위기를 변인으로 투입한 경우에만 여자의 직장 내 괴롭힘 피해를 일관되게 예측하였으며, 사회적 회피는 모든 경우에 여자의 직장 내 괴롭힘 피해와 관련이 없었다. 다만, 의사소통 분위기와 사회적 분위기가 좋지 않은 것은 그 자체로 여자의 직장 내 괴롭힘 피해를 증가시키는 것으로 나타났다. 마지막으로, 본 연구의 결과를 바탕으로 직장 내 괴롭힘의 예방과 개입에의 시사점을 논의하였다.
