The purposes of this study were to analyze the home economics(hereafter HE) curriculum in Victoria State, Australia, and to derive the implications for the HE curriculum in Korea. To accomplish the purposes, the contents of the curriculum were analyzed through the relevant web pages, and the actual conditions of the HE curriculum implementation were identified through e-mail and interviews with HE teachers and administrator. The results of this study were as follows. First, the HE curriculum for F-10 was one of the cross-curriculum resources based on the content descriptions and achievement standards of 'Design and Technologies' and 'Health and Physical Education' curriculum. Because the HE curriculum is competency-based curriculum and did not stipulate what was to be taught then, HE teachers had lots of autonomy in organizing and operating the curriculum, which led to the need for professionalism. Second, VCE subjects, both 'Food Studies' and 'Health and Human Development', which are HE elective curriculum for 11th and 12th graders, require students to take written tests produced by the VCAA. Because there are no specific details to be taught in the curriculum, the HE teacher had the need to devise and operate various classes to foster problem-solving skills, critical thinking skills, etc. Third, HE teachers had the discretion to create all the subject names, contents to deal with, and evaluations to prepare for the school curriculum, and thus were exerting their professionalism. This was due to the fact that the system was well equipped and VCE subjects were audited, even though teachers' performances were related to their individual competencies.

MOOC (Massive Open Online Course) is an online course aimed at limited participation and open access via the web. There is even the prospect that MOOC may break down the existing university system and open a new horizon of education. However, MOOC is going differently from the first prospect that it would threat the existing higher education institutions. So this study wishes to provide a starting point of discussion that we can produce and utilize MOOC to fit our situation of higher education by revealing the inherent problems of MOOC. MOOC is a basically online education, so that it cannot help inheriting the essential weakness of the existing one: the interaction, supervision and evaluation. The newly added concept 'massive' raises the problem of class size which is the most sensitive part in the field of education. The concept 'open' reverses a customized education because MOOC is a kind of video clips of a lecture for unspecific massive learners. As a conclusion, we predicts that MOOC will be positioned as a higher education service for very prominent learners in self-led learning ability and people who cannot access even traditional online higher education institutions. Also MOOC is highly likely to be used as a means of Flipped Learning in universities. Therefore, considering these points in the future, we need to develop MOOC to suit these targets.

The market volume of urban regeneration projects has steadily increased, thereby mixed-use development also shows significant market growth. However, previous researches on urban regeneration mainly deduced suggestions and plans for institution improvement based on comparison between projects implemented the inside and outside of the country. Whereas, researches on project management closely related to project success were limited, particularly in performance management. Accordingly, this research aims at developing a program performance management framework for public clients so as to succeed mixed-use development projects. Through extensive literature review and expert interview, this research developed performance indices for diverse facilities, risk management framework and integrating method of program performance score. The proposed framework is able to consider total life cycle from basic planning to maintenance phase and to check real-time performance level. Moreover, risk management framework can periodically assess and control the level of inherent risks within performance indices. The results can contribute to improve existing performance management practices and be basis for a web-based system developed in future.

User-Perceived application-level performance is a key to the adoption and success of CDMA 2000. To predict this performance in advance, a detailed end-to-end simulation model of a CDMA network was built to include application traffic characteristics, network architecture, network element details, and protocol features. We assess the user application performance when a Radio Access Network (RAN) and a Core Network (CN) adopt different transport architectures such as ATM and If. For voice Performance, we found that the vocoder bypass scenario shows 8% performance improvement over the others. For data packet performance, we found that HTTP v.1.1 shows better performance than that of HTTP v.1.0 due to the pipelining and TCP persistent connection. We also found that If transport technology is better solution for higher FER environment since the IP packet overhead is smaller than that of ATM for web browsing data traffic, while it shows opposite effect to small size voice packet in RAN architecture. Though simulation results we showed that the 3G-lX EV system gives much better packet delay performance than 3G-lX RTT, the main conclusion is that end-to-end application-level performance is affected by various elements and layers of the network and thus it must be considered in all phases of the technology evolution process.

The purpose of this study is to examine the concept of civic journalism and the contents of Korean Internet newspapers that might reflect the possibilities of this new medium for civic journalism practices. This study examined how far and deep civic journalism practices have extended into Korean Internet newspapers as journalism's new tradition. More specifically, this study analyzed news articles of Korean Internet newspapers to uncover any differences among civic journalism Internet newspapers with different citizen reporter systems. The composite measure based upon ten elements of civic journalism practices was used as indicator of civic journalism practices. To obtain systematic data on news offered by Korean Internet newspapers on the World Wide Web, four major Internet newspapers, including Ohmynews, Ngotimes, Netpinion and Pressian were examined by a content analysis in April and May of 2003. Findings of this study reveal that many Korean newspapers do not fully exploit the opportunities and advantages offered by the new medium for civic journalism practices in online environments. Both aggregate and individual level of analysis for the civic journalism index reveal that there are some differences between non-civic journalism and civic journalism Internet newspapers using citizen reporter systems. However, overall performances of civic journalism Internet newspapers are not good enough to support the argument that civic journalism is well practiced in Korean Internet newspapers. Nonetheless, it would not be fair to conclude that Korean Internet newspapers have totally ignored the Internet's potential to increase the civic journalism performance in online environments.

Recently, a concern about hollow core precast concrete (PC) slab has been increased as a method to improve the construction ability by reducing the self weight of structures during the construction. Hollow core slab which is known as a typical PC slab in domestic construction of PC building has a problem to put shear reinforcements in the web of element during the production of element in the factory. With regard to this point, recently, tripple ribs slab (TRS) which can be said as a new type of half PC slab system was developed. In TRS, it is possible to place shear reinforcements in PC element during the production of the element in the factory. This paper presents the shear test result of TRS which was done by one point loading test under simple support condition. Test parameters are the presence of cast-in-place (CIP) concrete and the contribution of lattice bars. From the test, it was found that the TRS has sufficient shear capacity to resist the design load and its strength can be predicted by the code equations for general beam. It is recommended to ignore the strength of lattice bar in the calculation of shear strength during the construction since its contribution is too low to be considered when CIP is not casted.

This paper consists of two parts: In the first part, we describe our work to build hierarchical knowledge base of digital library patron's research interests and learning topics in various scholarly areas through analyzing well classified Electronic Theses and Dissertations (ETDs) of NDLTD Union catalog. Journal articles from ACM Transactions and conference web sites of computing areas also are added in the analysis to specialize computing fields. This hierarchical knowledge base would be a useful tool for many social computing and information service applications, such as personalization, recommender system, text mining, technology opportunity mining, information visualization, and so on. In the second part, we compare four grouping algorithms to select best one for our data mining researches by testing each one with the hierarchical knowledge base we described in the first part. From these two studies, we intent to show traditional verification methods for social community miming researches, based on interviewing and answering questionnaires, which are expensive, slow, and privacy threatening, can be replaced with systematic, consistent, fast, and privacy protecting methods by using our suggested hierarchical knowledge base.

Hospitals in Korea have been increasingly using physician assistants (PA) as an alternative way of dealing with the shortage of residents. However, some incidents of a Physician's Assistant practicing beyond their legal scope require closer examination of the current PA's roles and functions. This study is a web-based survey designed towards targeting physician assistants in Korea (KPA) who practice delegated tasks under a physician's license. Currently, there are 2,125 KPAs working in 141 general hospitals and medical centers. Data from 704 nurses from who responded to the questionnaire were analyzed with descriptive statistics using the SPSS 12.0 program. Their mean age is 32.5 years with 8-10 years of clinical experiences, with males being more likely to be a PA. Despite of KPAs providing medical services and performing invasive procedures, only 13% of KPAs are licensed APNs (advanced practice nurse). KPAs have a low job satisfaction due to a lack of rewards and the necessity for providing illegal practices, and are experiencing identity confusion. The current KPA system is a transitional product of the change from the hierarchial structure to a more collaborative relationship between the medical and nursing departments. Providing adequate education and training, establishing protocols with legal protection, and developing professional independent scope of care are recommended to deliver safe and efficient medical services.
