The present study was aimed at investigating the effect of welding parameters such as welding current, electrode force(or squeeze force) and parts cleaning on the sound weld, and establishing the most reliable weld conditions for HWP(Heavy Water Reactor) fuel end capping with the resistance upset butt welding. Major results obtained are as follows. 1. The amount of sound weld was increased with increasing weld current(5.0-11KA) because the activated diffusion with increasing heat generation played an important role in eliminating the porosity and weld line in the weld interface. 2. It was found that weld current was not significantly influenced by the electrode force although the increase of it caused a slight increase of weld current and upset deformation. 3. Acetone rinsing before drying for the Zircaloy-4 end cap cleaning produced the reliable sound weld because it would remove the remaining solvent and surface films, and provided the uniform contact between the end cap and the tube. 4. The optimum welding conditions for fuel end capping by a resistance upset hytt welding are obtained as follows. weld current: 10-11KA, electrode force: 62-90KPa parts cleaning: vapor degreasing.rarw.water, acetone rinsing.rarw.drying.

In the Urban Regeneration Project, the scale becomes huge and the composition of participating organizations is complex. It is necessary to establish the master plan fast and effectively harmonize conflict options and interests in the early stage of the project. However, the master planner, who is tasked to establish the master plan, and the master planning team, are difficult to establish the master plan fast while effectively considering various and complex information related to regeneration. The Urban Regeneration Project is composed of various types of computer files like HWP, EXL, PDF, DWG and others. When the master plan is established, it is necessary to link the information items and physical files of urban generation in order to effectively save the files in storage for easy search and utilization. This study developed a prototype system to support participating subjects of the Urban Regeneration Projects. It will effectively utilize the information items in the physical computer files using information blocks and Metadata. The developed system provides the base to effectively manage large amount of documents in the early stage of the Urban Regeneration Project and make effective decision-making using the concept of data warehouse.

Objectives: The aim of this study was to investigate the effects of handwriting on the writing assessment, according to whether the handwriting is excellent or bad. Methods: A total of 24 elementary and middle school teachers participated in this study and assessed 6 original writings and 6 transcriptions of the same original writings using the HWP 2007 program. Six writings were collected from elementary students of 4th to 6th grades, 3 of 6 students presented with excellent handwriting and 3 of 6 with bad handwriting. The assessments were done according to the standards of propositional knowledge assessment (You & Jeong, 2008). Results: In the excellent handwritings, the rules of orthography and the contents of introduction of the original writings were scored higher than those in the transcriptions. The difference between transcription and original writing showed minus scores in original writing assessments and plus scores in transcription assessments. In the propositional knowledge score and its subscales scores - content knowledge, text knowledge, language knowledge and text context knowledge -, were differences in transcription assessments significantly higher than those in original writing assessments. Several assessment indices - clarity of the ending, contents of introduction, appropriate contents, rules of orthography, structured composition and various vocabularies showed significantly higher differences in transcription assessments than those in original writing assessments. Conclusions: The excellent handwriting could be assessed high and the bad handwriting could be assessed low. These results suggest that we should consider the effects of handwriting factors on the results of writing assessment and that the transcription could be used for an accurate writing assessment.

Candida albicans infections are often problematic to treat owing to antifungal resistance, as such infections are mostly associated with biofilms. The ability of C. albicans to switch from a budding yeast to filamentous hyphae and to adhere to host cells or various surfaces supports biofilm formation. Previously, the ethanol extract from Paeonia lactiflora was reported to inhibit cell wall synthesis and cause depolarization and permeabilization of the cell membrane in C. albicans. In this study, the P. lactiflora extract was found to significantly reduce the initial stage of C. albicans biofilms from 12 clinical isolates by 38.4%. Thus, to assess the action mechanism, the effect of the P. lactiflora extract on the adhesion of C. albicans cells to polystyrene and germ tube formation was investigated using a microscopic analysis. The density of the adherent cells was diminished following incubation with the P. lactiflora extract in an acidic medium. Additionally, the P. lactiflora-treated C. albicans cells were mostly composed of less virulent pseudohyphae, and ruptured debris was found in the serum-containing medium. A quantitative real-time PCR analysis indicated that P. lactiflora downregulated the expression of C. albicans hypha-specific genes: ALS3 by 65% (p = 0.004), ECE1 by 34.9% (p = 0.001), HWP1 by 29.2% (p = 0.002), and SAP1 by 37.5% (p = 0.001), matching the microscopic analysis of the P. lactiflora action on biofilm formation. Therefore, the current findings demonstrate that the P. lactiflora ethanol extract is effective in inhibiting C. albicans biofilms in vitro, suggesting its therapeutic potential for the treatment of biofilm-associated infections.

In the field of oriental medicine, many researchers head for the aim of standardization. To achieve this aim, oriental medical researchers have been carried out experimental research, statistical research, clinical research, philological research, etc., and, have published their results to journals. But, the declaration of Roman name of herbal formula is not united each other, on several article. So, we should prepare database to search in domestic and overseas, and should consider compatibility of internationally used search system. Also, it is need to use appropriate roman letters in oriental medical terms for people can use easily. We inquired the type of roman letters in the name of formula of article that were carried oriental medical journal, to find out appropriate roman letters and to the demands of the times. There were many cases that Korean name of formula is not correspond to the declaration of Korea roman letters. Also, the declaration of roman letters for preparation like as tang(湯), san(散), hwan(丸) etc. are not standardized. To facilitate making database and forming search system, now we suggest that we can standardize the declaration of Korea roman letters by using of Hangul(한글) word processor's toolbar which has transformation of roman letters.

Jungganbo is a writing method for the Korean traditional music. Since writing the Korean music needs to be done by hand and Chinese characters are used, only an expert musician might handle Jungganbo. In this paper, an authoring software tool for Jungganbo is introduced. It is useful for anybody who wants to compose the Korean tradition music with a computer. This tool also enables to standardize writing techniques of Jungganbo because a musical score was done by hands without using an authoring tool. In addition, this authoring tool can be easily used since its environment is very similar to other windows-based programs such as Ms-word and Hwp. Not only the beginners but also the experts can use this authoring tool for their Korean traditional music writing easily.

In the fungal pathogen Candida albicans, the yeast-to-hyphal transition occurs in response to a broad range of environmental stimuli and is considered to be a major virulence factor. To address whether the zinc homeostasis affects the growth or pathogenicity of C. albicans, we functionally characterized the zinc-finger protein Csr1 during filamentation. The deduced amino acid sequence of Csr1 showed a 49% similarity to the zinc-specific transcription factor, Zap1 of Saccharomyces cerevisiae. Sequential disruptions of CSR1 were carried out in diploid C. albicans. The csr1/csr1 mutant strain showed severe growth defects under zinc-limited growth conditions and the filamentation defect under hypha-inducing media. The colony morphology and the germ-tube formation were significantly affected by the csr1 mutation. The expression of the hyphae-specific gene HWP1 was also impaired in csr1/csr1 cells. The C. albicans homologs of ZRTl and ZRT2, which are zinc-transporter genes in S. cerevisiae, were isolated. High-copy number plasmids of these genes suppressed the filamentation defect of the csr1/csr1 mutant strain. We propose that the filamentation phenotype of C. albicans is closely associated with the zinc homeostasis in the cells and that Csr1 plays a critical role in this regulation.

As software grows more complex, it contains more bugs that are not recognized by developers. Attackers can then use exploitable bugs to penetrate systems or spread malicious code. As a representative method, attackers manipulated documents or multimedia files in order to make the software engage in unanticipated behavior. Recently, this method has gained frequent use in A.P.T. In this paper, an automatic analysis method to find software security bugs was proposed. This approach aimed at finding security bugs in the software which can arise from input data such as documents or multimedia. Through dynamic taint analysis, how input data propagation to vulnerable code occurred was tracked, and relevant instructions in relation to input data were found. Next, the relevant instructions were translated to a formula and vulnerable input data were found via the formula using an SMT solver. Using this approach, 6 vulnerable codes were found, and data were input to crash applications such as HWP and Gomplayer.
