Today, large enterprises are changing their team organization to group organization. These trends have brought work flexibility of project and manpower usage. However, communication among group members has become more complicated, and it has been found that ERP was not efficient enough to solve this communication problem. The main purpose of this study was to design a quick and systematic communication system for group project management, and Web-based Information Reporting System (hence forth WIRS) has been proposed. The main topics covered in this paper are design of functions and system architecture, process model design, database design, and implementation of the prototype. Focus group interview was conducted and user feedback was positive about main functions for WIRS and its overall impact on the enhancement of productivity.

This study examined the knowledge and practices of scientific inquiry displayed by three student teachers and two beginning teachers at secondary levels. Observations using the instrument of OTOP designed by the research team of OCEPT (Oregon Collaborative for Excellent in the Preparation of Teachers) generalized similar teaching strategies of scientific inquiry between student and beginning teachers, such as using group work for students' first hand experience, using concrete materials for experimentation or visual tools for demonstration, using questions for factual knowledge mainly without opportunities to understand how scientific knowledge is constructed. Those scientific inquiry activities were very confirmative ones to follow the steps without opportunities of understanding nature of science or nature of scientific inquiry. However, all participants in this study hold knowledge of scientific inquiry envisioned by the National Science Education Standards [NSES] (NRC, 1996), where students identify their hypothesis, use critical and logical thinking, and consider alternative explanations through argumentation as well as experimentation. An inconsistent relationship between participating teachers knowledge and practices about scientific inquiry resulted from their lack of pedagogy skills of implementing it in the classroom. Providing opportunities for these teachers to reflect on their beliefs and practices about scientific inquiry was recommended for the future study. Furthermore, increasing college faculty interest in new teaching approaches for upgrading the content knowledge of student teachers and beginning teachers was recommended as a solution, since those teachers showed evidence of influence by college faculties at universities in their pedagogy skills.

The ground work with of the research is constructed by a SCP method to improve clay ground in the sedimentary layer and sand ground in the reclamation layer at the same time as a reclaimed soft ground by reclaiming deep depth. Improved fine-grained soils in the sand ground decrease the ground improvement effect and have an influence on replacement ratio of SCP method. Fine-Grained soils which advances in sand ground reduces a from improvement effect, Makes affect in replacement ratio of SCP method. In this study, consideration about replacement ratio of sand ground, Tried to observe affects in replacement ratio of fine-grained soils SCP method of dredging reclamation ground. The result, replacement ratio which follows in the Japan Geotechnical Society experience-chart(1988) recording where fine-grained soils content will increase feebly, was visible the aspect which increases progressively, replacement ratio in compliance with Gibbs and Holts(1973) methods according to fine-grained soils increase is visible the tendency which decreases gradually with the enemy. Specially, according to case fine-grained content of Mizuno(1987) methods increases, replacement ratio suddenly was showing the trend which rises from of 50% and according to fine-grained soils increase was overestimated.

In order to prevent the maritime accident, all seafarers who work on fishing vessels over G/T 20 tons are required to undergo the basic safety training by the Seafarer's Act. 45% of domestic crews have boarded on the fishing vessels. However, the fishermen have been trained in accordance with the STCW(International convention on standards of training certification and watch-keeping for seafarers) Convention. But safety training courses for seaman do not reflect on the safety equipment and the limitation of the fishing vessel in the training contents which is organized in accordance with the merchant ship by STCW convention and code. Most of the fishing vessels are small fishing boat of less than G/T 80 tons. Small fishing vessels are operating with only a minimum of safety equipment that has been defined by the fishing vessel safety equipment standard. Due to the safety training that does not fit the situation of the fishing boat, the level of satisfaction by the crews onboard is low for the training. Furthermore, there is a difficulty in achieving the goal of safety education. In order to carry out the safety training that is suitable for fishermen, it is required to provide appropriate standards for the safety education of workers of small fishing boat, by understanding the current state of the domestic fishing vessels. The purpose of this study is to define the aforementioned problems and to provide the standard for the safety education of fishermen. In order to complete the purpose, the research team has conducted a analyzation for registered domestic fishing vessel and safety equipment standard.

Mind map is a very useful technique for brainstorming. Therefore, it can be effectively used for collaboration as a creative group conception. However, existing mind map software is not possible to collaborate because it is difficult to share mind map or discuss among members. In this study, we developed a mind map system that can support collaborative work as well as individual authoring and editing. This can incorporate individual mind maps of members into mind map of team, share and discuss them, and modify the mind map. This is convenient because it does not require a separate program installation, and verifies usability to support the process of collaborative process through usability evaluation.

During the 1950s, the North Koreans rebuilt their capital-Pyongyang-as a modern city under the principle of Soviet urban design. One North Korean architect, Kim Jung-hee, has been widely credited since the late 1980s as the master architect of the General Plan of the city's reconstruction. While Kim Jung-hee played a crucial role in its reconstruction, his heroic image as the founding architect of Pyongyang is considerably attributed to North Korea's mythical narratives rather than his historical activities. This paper argues that Pyongyang's postwar urban design was not a work made by a single actor, Kim Jung-hee; rather, it was a long-term collaborative project in which a team of North Korean architects and Soviet technical advisors took their respective roles. Beginning in the late 1980s, North Korea, which had been struggling with economic decline and an increasing sense of lagging behind in its rivalry with its Southern counterpart, used heroic narratives during the 1950s' postwar reconstruction period as an important propaganda tool for their regime. In this mythical narrative of Pyongyang's reconstruction, massive economic and technical aid from other communist countries has often disappeared, and the memory of the architects who contributed greatly to the reconstruction but later purged in North Korea have also completely vanished. Kim Jung-hee, meanwhile, remained in this epic as the founding architect who rebuilt the city in faithful accordance with the leadership of Kim Il Sung.

This study was designated to investigate communication barriers of nurses in clinical settings. This study was done in 2 phases, first content analysis on descriptions of 50 nurses in three general hospitals and 40 nursing students on communication barriers for nurses in clinical settings, and second a survey to investigate the factors related to communication barriers and the relation between the nurse's characteristics and the extent of communication barriers in clinical settings from two nurses educators, 13 nursing students who experienced clinical practice and 71 nurses in 11 general hospitals. The results are as follows : 1. Through content analysis, 11 properties of communication barriers for nurses in clinical settings were identified. These were inappropriate communication style as a nurse, lack of professionalism, in appropriate control of emotions, lack of knowledge about the clincal setting, the lack of preparation about content of communication, the problem in trust relation, differences in priorities in needs, uncontroleable situation for nurses, inappropriate nurses' perception about patients, conflict with medical team and inadequate systematic support were identified and grouped in to four categories, communicator, message, feed-back and communication context. 2. The four factors in communication barriers for nurses in the clinical setting were identified and named as ambiguity in the nurses' position, lack of confidence, difference in perspectives with patients and in-adequate nurse-patient relationship. 3. There was a significant difference(F=5.31, P=0.0022, F=3.62, P=0.0316, F=2.80, P=0.067, F=9.01, P=0.0003) among the groups according to work place in rating the extent of the communication barrier in the clinical setting and in the four factors, the nurses working in the psychiatric patient unit rated the communication barrier in the clinical setting lowest among the groups. There was a significant negative correlation between the length of the nurses's carrier and the extent of communication barrier in three factors, ambiguity in the nurses' position, lack of confidence and inadequate nurse-patient relationship.
