Recently, photovoltaic systems have been devolved into much larger systems up to MW-scale. Photovoltaic industry participants give their focus on power generation capability of photovoltaic modules because their benefits can be decided from the amount of generation. The information on long-term performance change of photovoltaic modules helps to estimate the amount of power generation and evaluate the economic cost-benefits. Long-term performance of a PV system has been analyzed with operation data for 12 years from 1999 to 2010. In the first year, the amount of yearly power generation was 57.7 MWh with 13.2% capacity factor. In 2007, the amount of yearly generation was 44.3 MWh with 10.14% capacity factor, and in 2010, the amount was decreased down to 38.1 MWh with 8.7% capacity factor. The result means that long-term capacity factor has been 4.5% decreased for 12 years and that the amount of generation has been decreased 34.0% for 12 years which is 2.8 % per year. The latter capacity factor has been decreased faster than 0.20%, the average rate for 10 years. The performance decrease of the PV system is meant to be accelerated. The decrease of performance and utilization is due to aged deterioration of photovoltaic modules and lowering conversion efficiency of PCS.

Understanding awareness and wearing behavior of functional textiles for silver generation is expected to contribute to clothing products development to improve and maintain their health and marketing strategy fit for user characteristics. For empirical research, a survey was developed and the aged 50 and above were 332 respondents. The results of the study are as follows. First, the level of awareness for both comfort-oriented and health/safetyoriented functional fabrics in high health-conscious group was much higher than that in low health-conscious group. In number of wearing times, health body and high-conscious group wear comfort-oriented fabrics more frequently, while weak body group wear health/safety-oriented fabrics more often. The health-consciousness significantly influenced the possession of active sportswear with various functions. Second, the awareness of functional fabrics in exercise activities groups was much higher than that in exercise-conscious groups. High exercise activities group know more about the wet sensation-related fabrics and clothing materials for outdoor activities. Low exercise-conscious group put on health/comfort-oriented fabrics for casuals more frequent than functional fabrics for sportswear. High exercise activities group preferred to wear sportswear suitable for outdoor activities. The aged people have a lot of health/comfort-oriented functional casual wear appropriate for indoor activities regardless of exercise-consciousness. However, the more they enjoy exercise activities the more they are interested in functional sportswear. Even though they were unconcerned with exercise, older people are interested in functional casual clothes. As a conclusion, the high interest in health and exuberant activities in silver generation arose the necessity of new multi-functional clothing products.

The purpose of this research Is to inquire into the aspects of consumers' perception of age and their lifestyle and to reveal the effect of variability in spending behaviors themselves. A survey was carried out regarding the consumers of the new elderly generation aged 55 and above. 561 respondents were surveyed. residing in Seoul and Metropolitan areas. Factor analysis from the exploratory reconnaissance, Cronbach's $\alpha$, K-average community and multivariate analysis, multi-recurrence and crossing analysis($\chi^2$ verified), were used for statistics analysis. In conclusion, the cognitive age only shared a marginal relationship with lifestyle, most people in their forties stood out in this part of the research. The change of the cognitive age and lifestyle of the new elderly generation is expected to be a variable in the clothing purchasing behavior in the future. As the population of the new elderly generation increases, there is a need for changing views towards the new elderly generation and there is no doubt that it is a main target within marketing trends in the elderly generation industry.

Background: This study aimed to investigate the association between employment transitions and suicide ideation among the echo generation. Methods: This study used survey data from the 2008 and 2010 Seoul Welfare Panel Study (Wave I, II). The sample population was restricted to the echo generation aged between18 and 31, and the total of 882 samples were included in the final dataset. Employment transitions were categorized into four groups. The groups were defined as 'employed-employed', 'unemployed-employed', 'employed-unemployed', and 'unemployed-unemployed'. We used logistic regression to find out the association between employment transitions and suicide ideation among the echo generation. Results: 'Employed-unemployed' and 'unemployed-unemployed' groups were likely to have an association with depression (odds ratio [OR], 1.49; 95% confidence interval [CI], 1.46 to 1.51; OR, 1.57; 95% CI, 1.56 to 1.59) accordingly. 'Unemployed-unemployed' group also was related to suicide ideation (OR, 1.39; 95% CI, 1.36 to 1.42). Interestingly, 'unemployed-employed' group showed a strong association with suicide ideation among the echo generation (OR, 3.85; 95% CI, 3.75 to 3.95). Conclusion: Experience in unemployment increases the risk of depression and suicide ideation. Moreover, the precarious job also increases the risk of suicide ideation.

This study analyzes the operational characteristics of 311 aged and non-aged residual current circuit breakers (RCCBs) in low-voltage consumer contexts. It investigates the influence of external temperature and harmonics based on the rated current multiples. To simulate temperature variations, a convectional oven was used around the circuit breakers. Additionally, the generation of harmonic reference signals and data measurement for overcurrent experiments were conducted using NI SCXI, myDAQ, and LabVIEW. An observation revealed that as the ambient temperature increased, the operating time of RCCBs decreased in the time delay region. This was attributed to the faster response or bending of the bimetal, which is the tripping element. However, aged RCCBs encountered challenges with tripping outside the protective curve. The operating time of the circuit breakers exhibited an acceleration influenced by the order and content of harmonic currents, potentially leading to malfunctions. Aged RCCBs demonstrated faster operating times than their non-aged counterparts. However, the difference in operating time varied based on the manufacturer's and operating environment of the RCCBs. Frequent malfunctions of RCCBs can result in power outages. In cases where these circuit breakers fail to operate, they can lead to secondary damages, including electrical fires and shocks. Consequently, it is imperative to consider the operating environment of RCCBs and provide appropriate replacement cycles to mitigate these risks.

The purpose of this study is to present a desirable model of memorial rites on the basis of their essential significance, as recognized by middle-aged housewives. This study was based on an interview survey that was conducted with 40 housewives in their 40's and 50's who live in Seoul. The interviews were carried out from August 1, 2009 to October 20, 2009, using a semi-structured questionnaire. The main results of this study can be summarized as follows: First, the middle-aged housewives recognized the significance of memorial rites as an expression of their sincerity, or as a cultural demonstration of affection commemorating their ancestors. Secondly, the housewives mentioned possible changes to different memorial rites depending on the will of their children's generation. These included a grafting of different memorial rites between religions, or a shift of the memorial rites to a religious institution or a memorial facility, in addition to maintaining the current practice in one's home. Thirdly, we proposed memorial rites that are carried out in one's home (Confucian, Christian, Confucian plus Catholic, or Confucian plus Buddhist style), a religious institution (Catholic church or Buddhist temple), and a memorial facility (arboretum, graveyard or enshrine facility).
