The sample of this study consisted of 140 informal caregivers who provided care to the older adults(over 60 years of age) in Great Cleveland, USA. Self-rated questionnaires were utilized to collect information. The purpose of the study was to identify coping strategies most frequently utilized by informal caregivers of older adults and to examine predictors of the caregivers' health responses to the caregiving situation applying Lazarus and Folkman stress model(1984). Stepwise multiple regression was used to identify significant predictors among caregivers' demographic-socio-economic factors, older adult's dependency of activities of daily living(ADLs), caregiver's appraisal to the caregiving situation, and coping strategies. Informal caregivers (N=140) included in the study utilized help-seeking and problem-solving coping strategies more than self-blame and minimization of threat coping strategies. Caregivers' responses to the caregiving situation were observed by caregivers' perceived physical health, depression and life satisfaction. For perceived physical health, threat appraisal, older adult's dependency on ADLs, existential growth coping strategy, and monthly income accounted for 25% of the variance. Caregivers who appraised the caregiving situation as more threatening, reported higher dependency on ADLs, used more existential growth coping strategy, and had higher monthly income reported better physical health. For depression, threat appraisal, stress appraisal, existential growth coping strategy, self-blame coping strategy, and monthly income accounted for 48% of the variance. Caregivers who used more existential growth coping and less self-blame coping, appraised the situation as less threatening, less stressful, and had higher monthly income reported less depression. For life satisfaction, self-blame coping, existential growth coping, monthly income, stress appraisal accounted for 49% of the variance. Caregivers who used more existential growth coping, less self-blame coping, less stress appraisal, lower monthly income reported better life satisfaction. In conclusion, informal caregivers in this study utilized positive coping strategies such as problem-focused, existential growth, help-seeking, rather than negative coping strategies including self-blame. When they utilized positive coping strategies more often, caregivers experienced higher perceived physical health, higher life satisfaction and lower depression. Therefore, nursing intervention which utilized positive coping strategies is needed to enhance informal caregivers to have positive health responses to the caregiving demands.

To explain the horizontal expansion of a rhizomatous perennial, Convallaria keiskei(lily-of-the-valley), in a study site of Chunchon, Kangwon Province, Korea, ramet growth and clonal structure were studied. Remarkable growth stategies were clarified. First, the timing for the successive phenological events such as sprouting. flowering and rhizome growth for lily-of-the-valley was fitted to exploit early spring when the canopy of overstory was opened. Second, these events were supported by effective matter allocation pattern: for example, two-year investment for new rhizomes enabled the first year ramets to mature in six weeks after sprouting and to grow up to 85% of the leaf area of perennial ramets. Finally, the ramet population was increased by local disturbances such as freezing, herbivory and collection by human. The rule that a clone was supposed to produce one new thizome per year was broken by occasional disturbances. Then, up to 5rhizomes from latent bur could be redeveloped. Based on clonal structure, 80% or total clones have from 1 to 4 ramets. this means there have occurred minor disturbances. Therefore, in conclusion, the successful flourishing of lily-of-the-valley came from its effective frowth strategy to take advantage of site disturbance.

To study marketing strategy changes caused by Korea fashion industry development process, the fashion marketing strategy changes of Japan, considered as the most similar one of Korea, was compared. At each period, p! roper cost efficiency strategies, product differentiation strategies, and market segment strategies has been selected and applied. The fashion industry foundation period namely practical usage clothing period of Korea follows 10 years after one of Japan. 90's highly sensitive fashion period namely fashion industry growth period follows 5 years after one of Japan. As entering to fashion industry maturity period with global competition, the time difference falls to less than 5 years. With hosting of 2002's World-Cup, Korea's global competitiveness has increased, and it appears to be possible of being fashion market leader in East Asia and Japan's rival on an equal footing.

This research analyzes the current state of the semiconductor industry delivering the prediction for the future development of the semiconductor industry along with some semiconductor memory's responsive strategies. In the 2014, top 10 semiconductor companies were targeted and studied its growth based on its profitability and growth indications in perspective during three years. The system semiconductor industry with the increase in Hyper-scale customers, proactive actions in the technology consortium, is polarizing caused by increased R&D expense to ensure process scaling limits and high performance, and some results have shown: PC and Mobile slowdown and growth recession phenomenon due to IoT's unclear direction. The leading company is to secure new growth engines through 'Acquiring'. While as the subordinated companies following this consecutive survival through the 'Acquired', the future of system semiconductor industry is to strengthen the market dominance and its techniques by concentrating on the reorganization of the market by few large companies. Accordingly, the semiconductor memory industry is expected to reach the limit of its expansion to domain of system semiconductor, and it is highly suggesting the need of the 'Memory Life Extension' growth strategy.

Availability of reliable and affordable energy supply is a prerequisite for economic growth. Renewables are the third largest contributor to global electricity production after coal and natural gas and account for a share of 18%. Power generating capacity from renewables has increased to around 900GW by the year 2007. Today biodiesel fuels have been in commercial use in many countries and recently the world-wide biodiesel market has experienced considerable growth, which is partly due to various tax concession programs and other financial incentives. In Korea, biodiesel has already been used for transportation fuel, but not used for power generation fuel yet. Korean government has a strategy for renewable energy propagation, especially the goal of power generation amount by renewable energy is 3% of total power production by 2012. This paper focuses on the feasibility study for adaptability and strategy of using biodiesel as power generation fuel. The study also has the plan to replace the fuel of thermal power plant, gas turbine and distributed power system. As the increase of biodiesel fuel, I look forward to environment-friendly power generation and the strategy of Renewable Portfolio Standards(RPS).

This paper proposes a new non-homogeneous Poisson process software reliability growth model based on the coverage information. The new model incorporates the coverage information in the fault detection process by assuming that only the faults in the covered constructs are detectable. Since the coverage growth behavior depends on the testing strategy, the fault detection process is first modeled for the general testing strategy and then realized for the uniform testing. Finally the model for the uniform testing is empirically evaluated by applying it to real data sets.
