This study measures the relationship between labor productivity and national competitiveness. Through the shift- share analysis method, the paper has separated labor productivity into three factors: static shift effect, dynamic shift effect and endogeneous effect. Next, in combination with the Granger causality test, the paper examines the relationship between the factors constituting labor productivity and competitiveness during the period from 2005 to 2017. Research data is collected from General Statistics Office and annual global competitiveness reports. The results show that the interaction between labor productivity with global competitiveness index (GCI) in Vietnam has similar variation. Nevertheless, when separating labor productivity into three effects, this relationship shows more clearly that the impact of labor productivity on GCI scores is mainly caused by endogeneous effect, not by static shift effect or dynamic shift effect. Therefore, in order to improve its competitiveness, Vietnam should focus on a number of solutions: reforming the education system towards developing thinking capacity and creative capacity; fostering industrial manners to create dynamic and flexible workers; building the State with sufficient capacity to implement consistent and transparent policies; formulating policies to attract all economic sectors so that they actively participate in the field of human resource training for the country.

It has become important to manage plant data effectively and to share these data among different organizations that are located in different places and participate in a variety of lifecycle phases. ISO 15926 is an international standard for integration of lifecycle data for process plants including oil and gas facilities. This standard consists of several parts providing a generic data model, reference data, and implementation methods. iRINGTools is a tool developed for the exchange of plant design data. This tool supports the implementation methods specified in ISO 15926. In this paper, the exchange of plant design data using iRINGTools is investigated. For this, sample P&ID data was modeled and data exchange experiment was performed. From the experiment, a data exchange procedure based on ISO 15926 is established and design data types that can be practically exchanged using ISO 15926 were identified.

In this research, we have carried out an experiment with grade 10 students. Students will be choosing their roles and creating their own script in relation to the environmental problems such as the seriousness of global wanning and the mutation of ecosystem. Throughout this process, they will come up with a solution to the problem In addition, we will assess students' knowledge achievement as well as the changes in attitudes toward environment, and analyze whether the role-play method of education is efficient or not. According to the research result, we have confirmed that the method of role-play as a education tool was more efficient than the traditional lecturing method. Students experienced higher rate of knowledge acquisition and more optimistic effects on their attitudes toward the mutation of ecosystem and also the seriousness of the global wanning. Students also pointed out in the interview that the role-play allowed them to share their thoughts with other classmates, which were not carried out frequently in the traditional education system In addition, each member of groups could participate cooperatively with teammates, which ultimately helped them to develop scientific and introspective ways of thinking.

IT convergence plays a key role in increasing the value of goods and services in other industry sectors. The government has enhanced the policy and institutional support for convergence technology development and technology commercialization. Some of the leading companies already achieve performance through the strategic IT convergence. However, in order to maximize the benefits and performance of IT convergence, policies should be established from the viewpoint of industrial ecology and many companies can participate in and share benefits of IT convergence business. From an industrial ecology perspective, this study suggests a role of the government, keystone enterprise, and other stakeholder for promoting the IT convergence using analytic hierarchy process(AHP).

Purpose: This phenomenological study aimed to identify breast cancer patients' experience of unkindness of healthcare providers. Methods: Ten participants who were diagnosed with breast cancer were recruited to participate in the study and asked to share their experience related to healthcare providers. Data were analyzed using the phenomenological method of Colaizzi. In-depth interviews were conducted from November, 2014 to March, 2015. Results: Seven consistent categories and fourteen theme clusters emerged from collected data. The seven themes were 'being treated thoughtlessly', 'not giving special services for breast cancer patients', 'cold and authoritative manner', 'incomplete explanation', 'not accepting an appeal', 'being sorry for having short consultation hours', and 'unskilled and careless treatment'. Conclusions: It is needed to develop health care services in the view of beneficiaries. This may reduce the patients' experience of unkindness of the healthcare providers and improve the satisfaction of health care service.

The purpose of the city planning is to share the future image of the area where all citizens sympathize and to function as tools to implement a policy. Recently, the city of Seoul has established the community plan to manage the city as neighborhood units, but there are several issues that need to be addressed, such as lack of practical strategies. Therefore, this study studied the neighborhood unit plan in terms of feasibility. The comparative analysis is the masterplan of the City of Seattle in the U.S and the city of Yokohama in Japan, which are known to accomplish advanced urban planning. As a result, three factors were needed; there are 1) a masterplan that acts as an action plan, 2) administrative support tools such as financial and human resources that encourage people to participate in urban planning with enthusiasm, and 3) a management system that continuously manages the plan itself. This result is expected to be a reference for the establishment of method for the implementation of neighborhood unit plan in Seoul.

In this paper, we proposed an efficient medium access protocol to share single transmission medium for several stations. There are two well known types of medium access protocols: collision allowance and collision avoidance, and each of them is adopted to their own suitable network with advantage. Our proposed protocol have channel reservation facility based on collision allow medium access protocol, CSMA/CD. In a collision, the stations delay collision with generating pseudo collision signal to reserve channel. Then, the collision terminates and the stations, which reserve channel successfully, participate the next competition with higher medium access probability. We show that the proposed protocol reduced collision times and improved utilization of the channel.

Cyber school community appears to have essentially emerged from the needs for interactive communication, which would not be easy in normal school environments. Message board, chatting rooms and e-mails allow students to connect with each others, share news, find ways to help study, or post personal stories. The purpose of this paper is to give a set of guidelines, based upon the direct observations and questionnaire analysis, for utilizing the cyber school community of elementary school children. The following conclusions are provided; the appropriate ate goal needs to be set before the cyber school community is to be developed; the balance between the off-line and on-line interaction needs to be maintained; actions for motivating students to participate in the cyber community need to be taken by teachers.

ThruBook is a collaborative work platform based on ebook documents, supporting synchronized group work sessions. Using this platform, users can participate in a group session based on a same ebook, and share group actions synchronously. In this paper, we consider annotations as all kinds of additional data on ebooks, including bookmarks, memos, and figures. Also, model shared actions such as sharing/navigating these annotations. As a result, we could model all collaborative actions as annotations, and propose a collaborative work model as communicating annotation objects between session participants. This approach implemented in ThruBook platform could easily model shared actions in collaborative systems. The collaborative work platform implemented in ThruBook can be applied to other types of collaborative work systems.
