With the diffusion of the Internet, firms try to electronically collaborate with their partners in order to cut costs and gain profits. This, electronic Partnership, called 'Collaborative IT' is quite popular between large purchase enterprises and small-to-medium sized sub-contractors. This study investigates such relations. This study proposes three groups of research variables-interorganizational relationship, collaborative IT activity, and firm performance. the interorganizational relationship consists of trust, commitment, and asymmetry of commitment. Collaborative IT activity is composed of information sharing and workflow integration. The ultimate dependent variable is firm performance. It is hypothesized that the relationship factors influence the level of collaborative IT activity, while the latter in turn affects the firm performance. The relationship factors nay also directly affect the dependent variable. In addition, collaborative IT motive, as a moderating variable, may influence the causal relationship. By means of survey, ore hundred and eighty-two responses were obtained. Most sample companies are small-sized, in the manufacturing sector. The analysis of data reveals that both trust and commitment positively affects the level of collaborative IT activity, while asymmetry of commitment has negative effects. The workflow integration is significantly related with firm performance. Information sharing, however, has no signific3nt effects. Furthermore, asymmetry of commitment shows reverse relationship with firm performance. Collaborative IT motive works as a moderating variable between information sharing and firm performance. Finally, workflow integration is believed to mediate between relationship factors and firm performance.

This paper explores, explains and describes a framework for analyzing collaborative governance, decent work and innovation as fundamental elements of sustainable workplaces through case study of Philippine science and technology (S & T) parks. Rules, or the legal infrastructure, are particularly significant considerations that facilitate or hinder collaboration. Industrial relations/human resource (IR/HR) practices are essential to collaboration and decent work. Employee consultation and labor-management council or committee are examples of IR/HR practices that might contribute to collaboration and decent work in firms and workplaces in S & T parks as they are team approaches to production, too. Collaboration and decent work enhance the capacity to innovate. In the long run, collaborative governance, decent work and innovation tend to converge in the concept of sustainable development. The interdependencies and interactions among collaborative governance, decent work and capacity to innovate in firms operating in S & T parks make possible new solutions to new problems (i.e., innovation) and, thus, sustainable workplaces.

The rapid development of information technology has much influence on architectural design. Collaboration beyond time and space has been possible by networking the work environment and digital products. Thus, the virtual design studio on architectural design is getting more important than ever before. This research investigates a virtual design studio methodology for effective collaboration. The building design process and the communication model are studied and possible modes of design collaboration are defined. This paper proposes an internet-based Virtual Reality(VR) communication tool as well as new design methodology that we call the 'Hybrid Design Methodology'. We expect that this design methodology will dramatically increase design feedbacks, and thus results in better design alternatives. There are two issues involved in developing the collaborative virtual design studio: 1) an intuitive interface that presents collaborative relations, and 2) three-dimensional computer-mediated communication tool using sketch as a modeling method. Further research issues identified at the end of the research include developing algorithms that translate mapping images to polygons for the drafting phase in the design process.

In recommender systems which are used widely at e-commerce, collaborative filtering needs the information of user-ratings and neighbor user-ratings. These are an important value for recommendation in recommender systems. We investigate the in-formation of rating in NBCFA (neighbor Based Collaborative Filtering Algorithm), we suggest new algorithm that improve prediction accuracy of recommender system. After we analyze relations between two variable and Error Value (EV), we suggest new algorithm and apply it to fitted line. This fitted line uses Least Squares Method (LSM) in Exploratory Data Analysis (EDA). To compute the prediction value of new algorithm, the fitted line is applied to experimental data with fitted function. In order to confirm prediction accuracy of new algorithm, we applied new algorithm to increased sparsity data and total data. As a result of study, the prediction accuracy of recommender system in the new algorithm was more improved than current algorithm.

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.

Purpose: The purpose of this study was to investigate the effect of Situation-Background-Assessment-Recommendation (SBAR) reports on communication clarity and nurse-physician collaborative relationships. Methods: SBAR forms in one group were measured at baseline, at 2 weeks, and at 4 weeks postintervention. The subjects were 30 nurses who worked in a general ward of a general hospital in B city, Korea. A 45-minute SBAR education was provided to all subjects. Data was collected between September to October 2015. The collected data was analyzed using a repeated measure ANOVA. Results: After SBAR reports, levels of nurse's communication clarity and nurse-physician collaborative relationships were significantly higher than levels before SBAR reports. Conclusion: SBAR reports improved the communication clarity and nurse-physician collaborative relationships. It is recommended to use a lot of SBAR in clinical practice.

최근 사용자의 흥미에 맞는 아이템이나 서비스를 추천해 주는 추천 시스템에 대한 관심이 높아지고 있다. 최근 종료된 Netflix 경연대회(Netflix Prize)가 이 분야에 대한 연구자들의 연구 의욕을 고취시켰고, 특히 협력적 여과(Collaborative Filtering) 방법은 아이템의 종류에 상관없이 적용 가능한 범용성 때문에 활발히 연구되고 있다. 본 논문은 강화 학습을 이용해서 추천 시스템의 협력적 여과 문제를 푸는 방법을 제안한다. 강화 학습을 통해, 영화 평점 데이터에서 각 사용자가 평점을 매긴 순서에 따른 평점 간의 연관 관계를 학습하고자 하였다. 이를 위해 협력적 여과문제를 마르코프 결정 과정(Markov Decision Process)로 수학적으로 모델링하였고, 강화 학습의 가장 대표적인 알고리즘인 Q-learning을 사용해서 평가의 순서의 연관 관계를 학습하였다. 그리고 실제로 평가의 순서가 평가에 미치는 영향이 있음을 실험을 통해서 검증하였다.

Globalization has fuelled the desire for simplicity and flexibility in rules and processes within nations. de Soto (2000) calls for the simplification of rules to enable people to join the formal economy. Friedman (2005) echoes the need for simpler rules, to attract business and capital. Market-based approaches to governing have been adopted in many nations due to globalization. Recent developments demonstrate that such approaches fail. Globalization may lead to impoverishment in the absence of proper forms of governance (Cooney 2000). That is why it has the tendency to become a "race to the bottom." Regulatory measures can be costly, and the costs of doing business are uneven across nations. This unevenness is being used as a comparative advantage. Others call this regulatory competition (Smith-Bozek 2007) or competitive governance (Schachtel and Sahmel 2000), which is similar to the model of Charles Tiebout. Collaborative governance is an approach that governments could use in lieu of the competitive method. Mechanisms that enable stakeholders to exchange information, harmonize activities, share resources, and enhance capacities (Himmelman 2002) are needed. Philippine public policy encourages a shift in modes of realizing labor market governance outcomes from command to collaboration (Sale and Bool 2010B; Sale 2011). Is labor market governance and regional development in the Philippines collaborative? Or is the opposite - competitive governance (Tiebout model) - more evident? What is the dominant approach? This preliminary research tackles these questions by looking at recent data on average and minimum wages, wage differentials, trade union density, collective bargaining coverage, small and bigger enterprises, employment, unemployment and underemployment, inflation, poverty incidence, labor productivity, family income, among others, across regions of the country. The issue is studied in the context of legal origins. Cultural explanations are broached.
