The most concerning issue of these days is the energy crisis caused by increasing threat of dependence on imported oil and volatile market trend. Under these circumstances, the PHEV(plug-in hybrid electric vehicle) is drawing attention for the next generation's car which could give a chance to decrease the dependence on imported oil and reduce the environmental impact of vehicle. The fueling cost of PHEV, one of the core factor of decision about buying car, should be calculated in the circumstances of Korea to make sure that PHEV has competitive power in real market. The fuel cost saving of PHEV versus CV(conventional vehicle) is simulated and discussed in the condition of increasing gasoline cost, electricity rate, and city-gas rate. In conclusion, the PHEV60-FS shows the best economic feasibility when gasoline price goes up. The PHEV20 has the most stable economic feasibility as electricity rate increases. The fuel cell cogeneration system for RPG could be an alternative for charger of PHEV in the near future.

A stream data is a data set that is accumulated to the data storage from a data source over time continuously. The size of this data set, in many cases. becomes increasingly large over time. To mine information from this massive data. it takes much resource such as storage, memory and time. These unique characteristics of the stream data make it difficult and expensive to use this large size data accumulated over time. Otherwise. if we use only recent or part of a whole data to mine information or pattern. there can be loss of information. which may be useful. To avoid this problem. we suggest a method that efficiently accumulates information. in the form of rule sets. over time. It takes much smaller storage compared to traditional mining methods. These accumulated rule sets are used as prediction models in the future. Based on theories of ensemble approaches. combination of many prediction models. in the form of systematically merged rule sets in this study. is better than one prediction model in performance. This study uses a customer data set that predicts buying power of customers based on their information. This study tests the performance of the suggested method with the data set alone with general prediction methods and compares performances of them.

This paper describes a strategy of a daily optimal operational scheduling in cogeneration system for paper mill. The cogeneration system selected to establish the scheduling consists of three units and several auxiliary devices. One unit generates electrical and thermal energy using the back pressure turbine. The rest two units generate the energy using the extraction condensing turbine. Three auxiliary boilers, two waste boilers and three sludge incinerators operate to supply energy to the loads with three units. The cogeneration system is able to supply enough the thermal energy to the thermal load, however it can not sufficiently supply the electrical power to the electrical load. Therefore the insufficient electric energy is compensated by buying electrical energy from utility. When the operational scheduling is performed considering the environmental problem. This paper shows the simulation results for daily operational scheduling obtained using the evolutionary algorithm. This results reveal that the proposed modeling and strategy can be effectively applied to cogeneration system for paper mill.

The purpose of this research is to investigate elderly, middle-aged female consumers' design and material preferences for lounge wear and after understanding senescent women's propensity to purchase lounge wear. The subject of research were to those living in the Seoul and capital region and 612, which did not comprise missing values, were collected and used for data analyses. All the age groups including those in their 50s and 60s prefer jacket and pants styles the most and these styles are the most favored as lounge wear as well. Those in their 50s and 60s prefer a round neckline the most while those in their 70s favor a V neckline the most. Analyses of sleeve styles of senescent women show that all the age groups favor a straight set, or a sleeve design, the most. Although the aged people investigated in this research have relatively high purchasing power, it is found that they tend to buy low priced lounge wears. Reviewing all of the above-mentioned results, the prices of garments for senescent people will be set in consideration of their economic level, so that good quality commodities may be produced and sold at different prices.

Purpose - Gen Y college students have emerged as a profitable consumer segment because of their growing purchasing power and influence on others' buying decisions. Digital marketing is deemed effective in increasing Gen Y college students' knowledge of and interest in products and services. This research examined the effect of digital marketing on Gen Y college students'perceptions, attitudes and purchase intentions toward cotton clothing compared to that of conventional print marketing and no marketing. Research design, Date and Methodology -Data were collected from three different groups of college students from a large university in the U.S.: the group with no cotton marketing, those with print media marketing, and those with digital marketing. Result - The findings confirmed that college students who were exposed to cotton digital marketing displayed the highest level of agreement on the benefits of cotton clothing. They also exhibited the most favorable attitudes and strongest purchase intentions toward cotton clothing. Conclusions - To target Gen Y consumers effectively, marketers should consider a digital marketing strategy to promote their products and services.

In general, the decay of the residential district has been considered a phenomenon of old towns. But now it has become a problem of new development areas too, which have been a cause of the decay of old town. This study aims to investigate the decay of the residential district in the new development area. The survey site was Dunsan, a town-intown of Daejeon metropolitan city. The findings were as follows (:) 1) even in the new development area, a high level of vacancy ratio was evident. ; 2) among the buildings above ground, 1st floor showed the highest vacancy ratio, which means the 1st floor was allotted to too many commercial facilities relative to the buying power size in this district. ; 3) there were many conversions in response to the decay of the district, from residential to commercial, and commercial to residential. ; and 4) the allocation of each type of conversion showed a spatial pattern.

This study aims to look at the change in consumer awareness and behavior after Japan's 2013 nuclear power plant's radioactive water leakage and draw implications about them. Findings show that 81% of respondents decreased their consumption of fishery products after the nuclear incident, and kept on showing avoidance of imported fishery products including those from Japan. Also it showed that consumers more importantly considered safety when buying imported fishery products after the nuclear incident. The most common channel of receiving radioactivity safety information on fishery products were TV and online. However, the main reason for decreasing the consumption of fishery products was founded to be based on the inaccuracy of the information provided. However, many people said that they will increase their consumption of all fishery products if provided with accurate radioactivity information. Therefore, if accurate radioactivity information were to be spread effectively to the public, positive consumption rates of fishery products can be shown in the future. The inaccuracy of radioactivity safety information caused the rapid decrease of fishery products consumption in 2013 to be amplified. Therefore, this study showed the importance of the delivery of rapid, accurate and consistent information to consumers.

The young casual wear market has been recently increased by the great buying power of the target consumers, although they don't have their own discretionary income. The purpose of this study was to investigate clothing attitudes of the adolescent consumers of the young casual wear market according to the groups of personality types. The questions on introversion/extroversion of MBTI test were adopted to measure introversion/extroversion in personal characteristics. The questions in "The personality diagnosis of high school students" developed by Lee, Chongseung and Chung, Bummo were adopted to measure stability, dominance, sociability and autonomy. Variables of clothing attitudes were composed with attentiveness, modesty and conformity. A total 488 high school students in Seoul participated in the survey. SPSS Win 10 statistical package was used to analyze the data: frequency, t-test, ANOVA and factor analysis. After statistical analysis, the following results were found. Groups of introversion and extroversion, and groups of low, medium and high degree of stability, dominance, sociability and autonomy showed no significant difference based on sex difference and school types. Students who has a high extroversion showed a high degree of attentiveness in clothing attitudes. Students who has the lowest sociability and the lowest autonomy showed a high degree of attentiveness. Students with the lowest autonomy showed a high degree of conformity. The younger the students were, the higher their attentiveness and modesty in clothing attitudes.
