This study was conducted as a part of the project to establish professional development system(PDS) for teachers in Korea. This study aimed to provide a case of running a professional learning community(PLC) of teachers in science education based on the collaboration of a national university of education and its affiliated elementary school, in search of learning by participants and implications for professional development of teachers as well as for science teaching in elementary schools. Teachers and researchers who participated in the PLC were able to accumulate meaningful experiences through 11 rounds of meetings. It was not easy to secure enough time for meetings, but they were able to boost their self-confidence for science teaching and enhance the quality of lessons through these gatherings. Participating teachers had a chance to share instructional design, planning, strategies and practices, which include cases of guiding free-choice research activities among students, thereby to be motivated for improved science teaching for the future. The researcher participating in this PLC was also able to understand the identity of an elementary school, especially the affiliated school, and identify the reality and difficulties related to science teaching in schools. Experiences of participating in PLC are expected to help improve the quality of science teaching in affiliated elementary school and pre-service teacher education of the university.

Purpose: This study was conducted to examine the experience of nurse in comprehensive nursing care. Methods: Experiential data collected from 9 nurses through in-depth interviews. Participants were selected from nurses working in the comprehensive nursing care unit at general hospital. The main question was "Can you describe your experience in the comprehensive nursing care unit?" All interviews were recorded and transcribed, then analyzed using Colaizzi's method. Results: Nine themes were derived from the analysis: 'Practice nursing care', 'Feel thankful of the client', 'Difficulty in nursing due to absence of patients' guardian', 'Tired of over-demanding patient and distrust of guardian', 'Confusion regarding one's identity as a nurse', 'Not enough to support system', 'Insufficient pre-training for nurse and client', 'Requirement of work establishment for nurse and nurse aid', 'Concerns about low rewards and high safety accidents'. Conclusion: As a comprehensive nursing service, the nurses provided total patient care, and patient satisfaction and expression of appreciation increased. However, disadvantages were identified, such as patients' excessive needs, communication difficulties, lack of support systems, low compensation, and a high number of safety accidents. Therefore, systematic comprehensive nursing will be achieved if these shortcomings are addressed.

The use of Multiparty Conference service based on SIP for VoIP provides is gradually magnified, and the work for continuous development and standardization on SIP is in the process of advancing. But, currently it is impossible for SIP to support identity discovery and distribution of each participant for multiparty conference. In this paper, we propose a SIP extension for guaranteeing security on the multiparty conference using SIP by adding new method and reconstructing header informations. With this, it is also possible to identify discovery and to distribute each participant using SIP extension when a call is established for closed multiparty conference.

A new protein was cloned and identified as the sixth subunit of Choristoneura fumiferana origin recognition complex (CfORC6). The newly identified 43 kDa protein CfORC6 is much bigger than DmORC6 (25.7 kDa) and HsORC6 (28.1 kDa), though it's 23.85% identical to DmORC6 and 23.81% identical to HsORC6. Although the molecular weight of CfORC6 is close to ScORc6 (50 kDa), CfORC6 is only 14.03% identical to ScORC6. By alignment, it was found that the N-terminal of CfORC6 has about 30% identities with other ORC6s, but about 100aa of C-terminal of CfORC6 has no identity with other ORC6s. Like ScORC6, CfORC6 has many potential phosphorylation sites, (S/T)PXK. Like DmORC6, CfORC6 has leucine-rich region in the relevant site. Northern Blot showed that CfORC6 mRNA is about 2,000nt. Southern Blot confirmed that there is one copy of CfORC6 gene in spruce budworm genome. Western blot showed that infection of Cf124T cells with CfMNPV didn't affect the expression levels of CfORC6, at least up to 26 hr post infection.

As a rapid development of electronic commerce transactions in these days, the security and private protection problems became more important matters under the electronic transaction base. Because electronic transaction using electronic documents be carried without direct person to person meeting, there can be the possibility to use other's identity illegally without notice, and very hard to verify authenticity of transaction as well. In addition, it is very hard to find out that the electronic documents on the process of submitting is forged documents or not, and also have much difficulty in maintaining transmitting secret. Therefore, to solve such problems on electronic commerce transactions and electronic documents, the digital signature and certification system with cryptography skill is inevitably necessary. As the wide use of digital signature together with beginning of digital government and financial transaction, not only the issuance of electronic certification, but certification market came to gradually expand. In Korea, after enacting digital signature act in 1999, the act contents were expanded to the wide range of contents complying with global standards from the end of 2001 to April, 2002, including the new clause of certification problems. And the act was put into operation now. Therefore, in this paper, we'd like to suggest development scheme through the investigation on electronic certification related problems, such as, concepts, procedures, service conditions here and abroad.

Cloud storage is becoming more and more popular because of its elasticity and pay-as-you-go storage service manner. In some cloud storage scenarios, the data that are stored in the cloud may be shared by a group of users. To verify the integrity of cloud data in this kind of applications, many auditing schemes for shared cloud data have been proposed. However, all of these schemes do not consider the access authorization problem for users, which makes the revoked users still able to access the shared cloud data belonging to the group. In order to deal with this problem, we propose a novel public auditing scheme for shared cloud data in this paper. Different from previous work, in our scheme, the user in a group cannot any longer access the shared cloud data belonging to this group once this user is revoked. In addition, we propose a new random masking technique to make our scheme preserve both data privacy and identity privacy. Furthermore, our scheme supports to enroll a new user in a group and revoke an old user from a group. We analyze the security of the proposed scheme and justify its performance by concrete implementations.

The CLI(Consumer Life Information) is a new study to unite and create new values recognizing the importance of knowledge and information in information-oriented society based on domestic science and digital technology. The objective of this research is to define academic identity of consuming science and CLI, to analyze the theory, styles, manners, psychology and the concept of consumption, which is the base of consuming life, and to present the direction of CLI with tasks and three major axises of CLI. Nowadays, international order demands new paradigms from human beings. Especially, vision and creation of the values are settled as methodological ways considering the economic power. The CLI should be on the same horizon adjusting social change of pointing values and quality in consuming patterns of diversity and variety. Therefore, I would suggest the ways for the CLI to head for as follows. First, it is to perceive the 3 major Axises & Task of CLI. Second, it is to develope service (experiencing goods) and goods that can lead consuming lives. Third, it is to study merchandising strategy, to create new signs and symbols of goods, and to collaborate of R & D(reseach and developement) and Business. Fourth, it is to head for globalization. Consequantly, this study will be helpful to establish the theory of relationship between producer and consumer in fashion business included research and developments of qualitative goods.

This thesis is a kind of case report on the managerial difficulties and strategies to overcome them for the rural hospitals in Korea. We examined environmental situations and SWOT(Strength, Weakness, Opportunity, Threat) of the hospitals, and suggested some strategies to improve the hospital business through analysing secondary data and brief survey to staffs and patients at 3 case hospitals. Among the strategies were included establishment of their identity as community hospitals, positioning towards high-touch services rather than high-tech services to improve their competence. For this positioning, patient satisfaction should be emphasized to make rapport with the residents in the community, and a few service areas should be selected and strengthened. Emergency care and geriatric health services are recommended to be covered strongly, because rural hospitals are usually the one and only hospital in the region and rural communities have aged population structure. In addition to these, networking is necessary among rural hospitals nationwide and with local clinics and tertiary hospitals near urban areas. And also, complementary role division with community health post should be developed to lessen the competitive relationship between public and private sectors. To support these strategies, fresh organizational culture should be built up to make hospital staff creative and enthusiastic on their job. Finally, inducement of governmental assistance will be necessary to make the environment advantageous to the rural hospitals.
