This paper aims to analyze the competitiveness of the Korean Deep-sea Fisheries firms in the firm level. The extant researches on this topic have been done mainly in the macro-or industry-level perspectives and depended on the quantitative analyses using the aggregated data. The results of these researches are useful to figure out the main features of the industy, however, hardly give any implications on the strategic or competitiveness-related problems in the firm level. To accomplish the research purposes this study analyzes the competitiveness of the Korean Fisheries firms on the value chain scheme using qualitative tools. Specifically this paper focuses on the industry competition characteristics, key success factors, the competitiveness, and the supporting systems and policies of the Korean Government. Data are gathered by questionaire and analyzed by factor analysis and Kruska-Wallis one-way ANOVA. The results shows that the competitiveness of the Korean Deep-sea Fisheries firms is not behind the foreign competitors. However the resource securing, the market development, R&D investment are the main obstacles to the firms. The governmental supports are kedined to improve the competitiveness of the Korean Deep-sea Fisheries firms.

Objectives: The aim of this study was to compare the cyclic fatigue resistance of the WaveOne Gold Glider, ProGlider and One G glide path instruments in artificial doublecurvature canals. Materials and Methods: This study included 15 WaveOne Gold Glider (size 15/0.08), 15 ProGlider (size 16/0.08), and 15 One G (size 16/0.06) nickel titanium files. The files were used in accordance with the manufacturer's instructions until they were broken in artificial double-curvature canals made of stainless steel. The time to fracture was recorded via a digital stopwatch and the number of rotations until fracture was also calculated. The data were statistically analyzed via the Kruskal-Wallis test. Results: The highest average number of rotations until fracture of the files was found for the WaveOne Gold Glider, followed by ProGlider and One G in order. Statistically significant differences were present between all groups of files (p < 0.05). Conclusions: In our study, the resistance of the WaveOne Gold Glider nickel-titanium (Ni-Ti) file to cyclic fatigue in S-shaped curved canals was found to be higher than that of the ProGlider and One G Ni-Ti files.

Purpose: This study sought to compare the elemental constitution, morphological characteristics, particle size distribution, biocompatibility, and mineralization potential of Ortho MTA (OMTA) and ProRoot MTA (PMTA). Materials and Methods: OMTA and PMTA were compared using energy-dispersive spectrometry, particle size analysis, and scanning electron microscopy. The biocompatibility and mineralization-related gene expression (osteonectin and osteopontin) of both MTAs were also compared using methylthiazol tetrazolium assay and reverse transcription-polymerization chain reaction analysis, respectively. The results were analyzed by Kruskal-Wallis test with Bonferroni correction. P-value of <0.05 was considered significant. Result: The morphology of OMTA powders was similar to that of PMTA. The constituent elements of both MTAs were calcium, silicon, and aluminum. The mean particle sizes of OMTA and PMTA were 4.60 and 3.34 mm, respectively. Both MTAs had equally favorable in vitro biocompatibility and affected the messenger RNA expression of osteonectin and osteopontin. Conclusion: Within the limitations of this study, OMTA could be a promising biomaterial in clinical endodontics.

Purpose: The purpose of this study was to explore differences in health belief by compliance level with breast self-examination (BSE) and the predictors of BSE compliance among women. Method: Using a convenience sampling method, 163 women were selected for the sample. Data were measured for each participant during the period between December 2008 and February 2009, and analyzed by chi-square test, t-test, Kruskal-Wallis test with post hoc, and logistic regression analysis. Samples were categorized into three groups by the compliance level of BSE for the last 6 months: Never-performers (i.e, women who had never performed BSE), irregularly-performers (i.e, women who performed BSE at least once), and regularly-performers (i.e, women who performed monthly BSE). Result: Significant differences were reported among never-performers, irregularly-performers and regularly-performers correlated to age, level of education, mammography, ultrasonography, clinical examination, benefit, and confidence. There was no significant difference between irregularly-performers and regularly performers. The significant factor influencing compliance with BSE was 'confidence', which explained 33.7% of the variance in compliance with BSE. Conclusion: Women who had more confidence in their ability to perform BSE were more likely to practice BSE. It is necessary to develop the strategy to enforce woman's confidence in complying with BSE.

Purpose: The purpose of this study was to identify sleep patterns, alertness, and fatigue of shift nurses according to circadian types. Methods: The researchers' enrolled 17 nurses doing shift work in a tertiary hospital. To evaluate circadian types, a morningness-eveningness questionnaire (MEQ) was administered. Sleep patterns were examined using an actigraph for 14 days. To assess alertness and fatigue, Visual Analogue Scale (VAS) was used. The data were analyzed using ANOVA and Kruskal-Wallis test with a SPSS 21.0 program. Results: The researchers found that 17.6% of participants reported morning type, 47.1% neither type, and 35.3% evening type. Mean total sleep time (TST) was 6.8 h, mean sleep efficacy was 82%, level of alertness was 6.54, and level of fatigue was 5.49, regardless of the type of shift work. Evening type nurses had higher variation in TST and alertness, according to the shift patterns than other circadian type nurses. Evening type nurses also had higher fatigue levels than other circadian type nurses. Conclusion: Sleep, alertness, and fatigue were related with circadian types. These results suggest that circadian rhythm management in shift work nurses, particularly in evening type nurses is urgently needed to improve sleep patterns, alertness, and to decrease the level of fatigue.
