This study investigates the social network among authors to improve the quality of Panel researches. Korea Health Panel (KHP), implemented by the collaborative work between KIHASA (Korea Institute for Health and Social Affairs) and NHIC (National Health Insurance Service) since 2008, provides a critical infrastructure for policy making and management for insurance system and healthcare service. Using bibliographic data extracted from academic databases, eighty articles were extracted in domestic and international journals from 2008 to 2014, April. Data were analyzed by NetMiner 4.0, social network analysis software, to identify the extent to which authors are involved in healthcare use research and the patterns of collaboration between them. Analysis reveals that most authors publish a very small number of articles and collaborate within tightly knit circles. Centrality measures confirm these findings by revealing that only a small percentage of the authors are structurally dominant, and influence the flow of communication among others. It leads to the discovery of dependencies between the elements of the co-author network such as affiliates in health panel communities. Based on these findings, we recommend that Korea Health Panel could benefit from cultivating a wider base of influential authors and promoting broader collaborations.

Since Deng Xiaoping's implementation of the "One China, Two Systems" policy, mainland China and the other Chinese regions of Hong Kong and Macau have cooperated in various ways to work towards successfully developing China's overall economy and industries. Particularly, cooperation between Guangdong Province and adjoining Hong Kong have been contributing to China's development, and this study explores their industry conditions including their current two governments policies designed to promote collaboration. The two partners were in a cooperative relationship even before the handover of Hong Kong, beginning with a "front shop, back factory" model built on their respective comparative advantages in labor-intensive industries in the 1980s. This cooperation effectively propelled the Pearl River Delta Region's industrialization process and enabled Hong Kong to transform from a manufacturing industry-based economy to a service industry-based economy. From the early 2000s, Guangdong and Hong Kong diversified their collaboration project from culture to high-tech. Also, both authorities produced several types of policies not only to promote both industries but also to harmonize their two different economic levels and models. As a result, the Guangdong and Hong Kong economies have developed remarkably well during the past two decades and continue to form future plans that carry plenty of optimism. Nonetheless, this study showed discrepancies between engineers and scientists from the two areas in their perception of their technology and science cooperation. Hong Kong experts were more negative in their responses but noted some successes of the collaboration, while Guangdong's group showed overall positive responses. This difference results from an unbalanced role in cooperation. Hong Kong's side responds to cooperation plans and takes on leading roles with more frequency than Guangdong's side in actual cooperation project processes.

The Pareto principle, also known as the 80-20 rule, states that roughly 80% of the effects come from 20% of the causes for many events including natural phenomena. It has been recognized as a golden rule in business with a wide application of such discovery like 20 percent of customers resulting in 80 percent of total sales. On the other hand, the Long Tail theory, pointing out that "the trivial many" produces more value than "the vital few," has gained popularity in recent times with a tremendous reduction of distribution and inventory costs through the development of ICT(Information and Communication Technology). This study started with a view to illuminating how these two primary business paradigms-Pareto principle and Long Tail theory-relates to the success of virtual knowledge collaboration. The importance of virtual knowledge collaboration is soaring in this era of globalization and virtualization transcending geographical and temporal constraints. Many previous studies on knowledge sharing have focused on the factors to affect knowledge sharing, seeking to boost individual knowledge sharing and resolve the social dilemma caused from the fact that rational individuals are likely to rather consume than contribute knowledge. Knowledge collaboration can be defined as the creation of knowledge by not only sharing knowledge, but also by transforming and integrating such knowledge. In this perspective of knowledge collaboration, the relative distribution of knowledge sharing among participants can count as much as the absolute amounts of individual knowledge sharing. In particular, whether the more contribution of the upper 20 percent of participants in knowledge sharing will enhance the efficiency of overall knowledge collaboration is an issue of interest. This study deals with the effect of this sort of knowledge sharing distribution on the efficiency of knowledge collaboration and is extended to reflect the work characteristics. All analyses were conducted based on actual data instead of self-reported questionnaire surveys. More specifically, we analyzed the collaborative behaviors of editors of 2,978 English Wikipedia featured articles, which are the best quality grade of articles in English Wikipedia. We adopted Pareto ratio, the ratio of the number of knowledge contribution of the upper 20 percent of participants to the total number of knowledge contribution made by the total participants of an article group, to examine the effect of Pareto principle. In addition, Gini coefficient, which represents the inequality of income among a group of people, was applied to reveal the effect of inequality of knowledge contribution. Hypotheses were set up based on the assumption that the higher ratio of knowledge contribution by more highly motivated participants will lead to the higher collaboration efficiency, but if the ratio gets too high, the collaboration efficiency will be exacerbated because overall informational diversity is threatened and knowledge contribution of less motivated participants is intimidated. Cox regression models were formulated for each of the focal variables-Pareto ratio and Gini coefficient-with seven control variables such as the number of editors involved in an article, the average time length between successive edits of an article, the number of sections a featured article has, etc. The dependent variable of the Cox models is the time spent from article initiation to promotion to the featured article level, indicating the efficiency of knowledge collaboration. To examine whether the effects of the focal variables vary depending on the characteristics of a group task, we classified 2,978 featured articles into two categories: Academic and Non-academic. Academic articles refer to at least one paper published at an SCI, SSCI, A&HCI, or SCIE journal. We assumed that academic articles are more complex, entail more information processing and problem solving, and thus require more skill variety and expertise. The analysis results indicate the followings; First, Pareto ratio and inequality of knowledge sharing relates in a curvilinear fashion to the collaboration efficiency in an online community, promoting it to an optimal point and undermining it thereafter. Second, the curvilinear effect of Pareto ratio and inequality of knowledge sharing on the collaboration efficiency is more sensitive with a more academic task in an online community.

The term "Collaborative medical care" commonly used in South Korea refers to the case where doctors from different medical departments work together to treat a patient within the same medical institution. Therefore, "Collaborative medical care" represents the aspect of a medical team where various medical professionals collaborate based on their expertise to treat patients. Additionally, doctors from different specialties within the medical team engage in horizontal division of labor at an equal status, distributing legal responsibilities according to the principles of division of labor. The Supreme Court also acknowledges cases where multiple doctors collectively provide medical treatment through division of labor or collaboration and states that the doctor who initially attended to the patient must accurately inform the subsequent attending doctor about the patient's condition to enable appropriate measures. In medical institutions with multiple specialties, when doctors from different specialties collaborate to provide medical treatment, the doctor who attended to the patient initially must decide whether collaboration is necessary based on the patient's condition. Subsequently, they must inform the doctor from the relevant specialty about the patient's condition accurately to facilitate appropriate actions. The successor doctor who participates in collaborative medical care must actively communicate relevant treatment information related to the patient's condition with the predecessor doctor who requested collaboration, exchange opinions, and do so until the patient's treatment concludes. However, the determination of the necessity of collaborative medical care should be based on the patient's condition at the time, and it cannot be asserted that collaborative medical care is mandatory in all cases. Whether there is negligence in the decision about the necessity of collaboration will be assessed based on the legal principles of a doctor's duty of medical care.

How satisfied or dissatisfied people are with aspects of daily life such as housing, income, health, family, food, human relations, and work provides vital information about them. On the basis of a nation-wide random sample survey in Japan in October 2013, this article analyzes Japanese citizens' daily life satisfaction in a snapshot. The big picture of Japanese daily life is that they are more or less satisfied with their daily life, although income, work, and housing register lower levels of satisfaction in comparison to other aspects like food, family, human relations, and health. Their satisfaction is focused on food, family, and human relations.

Recently Renku (Haikai no Renga) is getting popular as well as Haiku in Japan. It was built up by Basho Matsuo, who was the most famous Haiku poet. It is said that Kyoshi Takahama proposed the name of "Renku" to distinguish it from "Renga" and "Haiku" in 1904. Renku meetings are held like Haiku ones regularly now in each place, and in several universities, they conduct a class exercise of Renku continuously. It is very important for plural persons to work together cooperatively. Poetry, Tanka, Haiku and Renku are usually composed of only letters. It sometimes happens that we add pictures to make them more attractive and to aim at synergy by collaboration (letters and pictures). However, the study to produce 3DCG animations of Renku has not been reported very much. Sowe studied to produce 3DCG animations work based on the rule of Renku and its evaluation.

Decentralized autonomous organizations (DAOs) is an effective and secure means to enable direct collaboration between people who want to achieve common goals in a digital environment, where believing each other without intermediaries from trusted third parties is difficult. DAO can flexibly implement most of the roles previously performed by existing organizations and finally aim for a new structure that functions independently without human intervention. Despite its technical and legal uncertainties and problems, DAO is rapidly expanding. This study examines trends such as the concept, use cases, participation methods, and deficiencies of DAO, which is called the future of work and helps to understand upcoming considerations.

BIM technologies store, share and integrate the information produced in each sector of the construction industry. From this point on, it increases the efficiency of the work. Currently, quantity take-off and process schedule are derived separately based on BIM technology. When calculating the quantity by process, relevant information shall be collected, reinterpreted, and reevaluated as required by the practice. The purpose of this study is to develop an integrated process and quantity management system through BIM collaboration and to build prototypes for steel structures. The main research is to build a construction BIM model for steel structures and a process BIM model through BIM collaboration. Furthermore, necessary information was selected and processed according to the user's needs for integrated management. Relevant integration outcomes are visualized graphically to maximize utilization. Through these studies, a system for integrated control of processes and supplies is provided, and the results are expected to contribute to the improvement of working efficiency and are easily and quickly reflected in design change and process change. In this study, we intended to enhance the usability of information by linking process schedules with quantity calculations based on BIM. Thus, the process for integrated control of the quantity of structural components by process unit and the BIM based schedule information was established. In addition, the efficiency of the information link of the integrated management system was considered for design changes and process schedule changes.
