Objectives: The current study reviews the implementation and evaluation of the Chronic Disease Self-Management Program (CDSMP) in the United States (U.S.) to illustrate the program's potential contribution to improving health among Korean adults with chronic conditions while saving healthcare costs. Methods: This study examines existing literature on the history, theoretical background, essential elements, and delivery outcomes of CDSMP with special focus on the successes and challenges to be faced in the implementation of CDSMP to Koreans with chronic conditions. Results: CDSMP is designed to empower people with chronic conditions to develop skills necessary for medical, social role, and emotional management of chronic conditions. Recent studies show the utility of CDSMP in achieving the Triple Aim health reform goals (i.e., better care, better health, better value). Lessons learned from the U.S. experience emphasize the importance of establishing evidence-based studies, collaborating with community partners, and diversifying funding sources to make CDSMP more sustainable. Conclusion: The current study demonstrates the replicability of CDSMP and potential for expansion in Korea. More concerted efforts among academia, government, and communities are needed to deliver CDSMP to Korean adults and identify its effectiveness within the Korean context in terms of meeting the Triple Aim goals of better care, better health, and better value.

Research on entrepreneurial gifted youth who have immense potential within the national economy in the near future is critical. The purpose of this article is to establish the proper goal and direction of longitudinal study on entrepreneurial gifted youth and to identify substantial research problems. In order to do a theoretical inspection around preceeding research related with the field, longitudinal study of entrepreneurial youth (including gifted education and entrepreneurship) was executed. As a result, the goal, 'the verification of whether entrepreneurs can be cultivated by educational interventions' was derived as an appropriate research direction. Also, 4 major research problems are presented: (1) Description of the features of entrepreneurial gifted youth and their developmental pattern, (2) Explanation of the effects of educational intervention on intensifying entrepreneurial giftedness, (3) Prediction which identifies the factors that influence the youths' success as eminent entrepreneurs, and (4) Control over promoting talented individuals and refining relevant policy and institutions. Implications and further research directions are also discussed.

The Internet has brought us a new paradigm called WEB 2.0 which inherently represents the openness, participation, sharing, and cooperation. The WEB 2.0 has rendered people to actively participate in the creation of information and to dynamically interact with others to build mutual knowledge-bases, introducing a whole new web environment. One of the most representative techniques demonstrating the value of the WEB 2.0 is the WIKI which is essentially based on the 'Collective Intelligence' and the 'Wisdom of Crowds'. So far, the WIKI has drawn lots of attention for its potential as an educational tool. In this research, we explored the educational potential of the WIKI by investigating various programs and web-based tools offering WIKI services, and then, analyzing the usage model and characteristics of its users. Based on the analysis, we developed a WIKI-based instructional model and also proposed concrete lesson plans adopting this model. Besides, we introduced preliminary methodologies on the active use of the WIKI in the Edunet and the Cyber Home Learning System as well.

Learning styles affect how students access and handle their task, so it is very important to understand how they study, when planning teaching-learning process, to enhance their potential to the maximum. In addition, in order to improve the quality of gifted education, there is a need to examine the curriculum and teaching-learning process which reflect learner characteristics. In this study, gifted student's preferred learning styles are investigated using questionnaires and learning style inventory. Also by analyzing the characteristics of the learners, it is hoped to get parents and teachers to understand the gifted who have various talents, and to support teaching programs for the gifted in order to develop their potential. This study shows that there are differences in the studying style between the gifted child and the average child. Namely, learner's physical and psychological environment can affect learning styles. Also there is a difference between the studying style which the gifted students prefer and the teaching style which teachers use most frequently. Programs for the gifted should be planned through better understanding of the characteristics of the learners.

There are two cases when the life of a sacrificial anode is shortened from the designed life: one case results from self-corrosion of the anode due to contamination by sea water in the other case, however, electrical current to protect some given steel piles overflows to protect other, adjacent non-protected steel piles. In this study, the variation of polarization potential of nine steel piles, being protected cathodically and with anode-producing current between anode and steel piles, was investigated. Parameters were varied, such as the eighth and ninth steel piles either connected electrically or not, and whether the ninth steel pile was protected by another sacrificial anode or not. The current produced by the sacrificial anode decreased when the ninth steel pile was cathodically protected by the anode of another pile. However, produced current increased when the ninth steel pile was not connected to another anode. The study concludes that the life of a sacrificial anode can be prolonged or shortened depending on whether adjacent steel piles are cathodically protected or not.

The diesel engine of the merchant ship has been aperated in severe environments more and more, because the temperature of the exhaust gas of a combustion chamber is getting higher and higher with increasing use of heavy oil of law quality, due to the significant increase in the price of oil in recent some years. As a result, the degree of wear and corrosion between exhaust valve and seat ring is more serious compared to other engine parts. Thus the repair welding of exhaust valve and seat ring is a unique method to prolong the life of the exhaust valve, from an economical point of view. In this study, the corrosion property of both weld metal and base metal was investigated using electrochemical methods such as measurement of corrosion potential, cathodic and anodic polarization curves, cyclic voltammogram, and polarization resistance in 5% H2SO4 solution. The test specimen was a part of an exhaust valve stem being welded as the base metal, using various welding methods. In all cases, the corrosion resistance as well as hardness of the weld metal zone was superior to the base metal. In particular, plasma welding showed relatively good properties for both corrosion resistance and hardness, compared to other welding methods. In the case of DC SMAW (Shielded metal arc welding), corrosion resistance of the weld metal zone was better than that of the base metal, although its hardness was almost same as the base metal.

The condition factor (CF) were calculated by the morphometric data, and gonadal maturation and reproductive potential associated with fecundities of indoor cultured Hapalogenys nitens were investigated by microscopic and morphometric analysis from August 2011 to October 2012. Monthly changes in the GSI and CF were closely related to gonadal maturation and spawning. The ovary consisted of a pair of saccular structure with many ovarian lobules, the testis is a pair of lobular structure with many testicular lobules. The relationship between total fecundity (F) and total length (TL) of fish was expressed as $F=0.0449TL^{2.7926}$($r^2=0.0653$), and body weight (BW) was expressed as $F=1.4492BW^{0.8964}$($r^2=0.0863$). In this study, some exceptional special cases and phenomena were observed: absolute and relative fecundities were not increased with the increases of total length and body weight, respectively. Absolute and relative fecundities were no concerned with the increases of age classes of total length (cm) and of body weight (g).

The observation and recommendation system was recently introduced for selecting gifted-students in science, and it has required to arrange the reliable and valid selection criteria that could identify the high potential competency of them. In this study, we explored the competencies that could help to discriminate gifted-students' inner properties, and also developed the dictionary based on them. The competencies were extracted from the proven previous competency dictionaries/models and examined by the structured survey and the focus group interview in order to ascertain the competencies of the science-gifted students. The results revealed that there were two competency clusters such as cognitive and affective domains. The cognitive cluster consisted of 6 competencies as follows: goal suggestion, planning, information collection and analysis, problem solving, higher-order thinking, and expertise and self-development competency. The affective cluster consisted of 3 competencies: confidence, achievement orientation, and curiosity competency. The dictionary categorized by the names, definitions, key elements, and behavioral indicators and their levels of the derived competencies was developed. Findings were expected to provide the implications on the selection criteria of the potential science-gifted students through the observation and recommendation system.

The East Sea including the area of this study is identified as a typical back-arc sea located in the backside of the Circum-Pacific volcanic and earthquake belt. Previous studies reported that the East Sea has begun to open by tensile force and formed its current shape. In this study, we investigate the regional tectonic structure of the East Sea using ship-borne gravity, magnetic, and satellite gravity data. The result of three-dimensional depth inversion shows that Moho depth of the study area is approximately 13-25km and inversely proportional to the thickness of the crust. In addition, as approaching to the center of the Ulleung Basin (UB), the thickness of the crust of the UB becomes thinner due to the extension caused by tensile force which had opened the East Sea.

High strength 7xxx aluminum alloys have been applied to automotive bump back beam of the some limited model for light weight vehicle. The aluminum bump back beam is manufactured through extrusion, bending and welding. The residual stress given on these processes combines with the corrosive atmosphere on the road spreaded with corrosive chemicals to melt snow to occur the stress corrosion cracking. The composition of commercial 7xxx aluminum has Zn/Mg ratio about 3 and Cu over 2 wt% for better strength and stress corrosion cracking resistivity. But this composition isn't adequate for appling to the automotive bump back beam with high resistance to extrusion and bad weldability. In this study the composition of 7xxx aluminum alloy was modified to high Zn/Mg ratio and low Cu content for better extrusion and weldability. To estimate the resistivity against stress corrosion cracking of this aluminum alloy by slow strain rate test, the corrosion atmosphere and strain rate separate the stress corrosion cracking from conventional corrosion must be investigated. Using 0.6 Mol NaCl solution on slow strain rate test the stress corrosion cracking induced fracture was not observed. By adding 0.3% $H_2O_2$ and 0.6M $Na_2SO_4$ to 1M NaCl solution, the corrosion potential and current density of polarization curve moved to active potential and larger current density, and on the slow strain rate test the fracture energy in solution was lower than that in pre-exposure. These mean the stress corrosion cracking induced fracture can be estimated in this 1M NaCl + 0.3% $H_2O_2$ + 0.6M $Na_2SO_4$ solution. When the strain rate was below $2{\times}10^{-6}$, the stress corrosion cracking induced fracture start to be observed.
