This study investigated consumers' energy saving behavior and perceptions concerning the effectiveness of their energy saving behavior. A nation wide survey was conducted involving 2000 households in urban areas and the data from 1767 households were used for the analysis. excluding cases with incomplete responses. Descriptive analysis, factor analysis, and regression analysis were applied. The results were as follows. First, electricity saving behavior was classified into three categories: Thrift (reducing energy consumption), Purchase (buying energy saving appliances), and Control (checking the energy consumption). Second, consumers rated Thrift as the best way to save energy. Third, education, age, and household income were significantly related to energy saving behavior and perceptions on the effectiveness of energy saving behavior. Consumers using above average levels of electricity tended not to practice energy saving behavior and not to positively evaluate effectiveness of the energy saving behavior. Lastly, the implications for public policies to promote energy saving behavior are suggested.

Purpose: To investigate the abilities to act and fear of falling in home-dwelling elderly. Methods: This study interviewed 351 home-dwelling elders residing in Seoul and Gyonggi-do using a Survey of Activities and Fear of Falling in the Elderly. Results: Of the 351 subjects, 203(57.8%) had activity restrictions. The main three activities that the subjects could not perform were going out when it is slippy, reaching something overhead and walking crowded places outside. According to general characteristics, performable activities were significantly fewer in subjects perceiving that their health status was low that those perceiving that their health status was high. On a scale of 3 points for fear of falling, the average score of the subjects was 1.46. The highest score of fear of falling was 2.62 for the activity of going out when it is slippery, next 1.87 for the activity of reaching something overhead. There was a significant inverse relationship between subjects' abilities to act and fear of falling. Conclusions: The significant variables associated with fear of falling were gender(female), educational background, economic status (low-income), and experience of falls during the last one year. Thus further study is necessary, focused on the vulnerable population in order to prevent falls and to reduce fear of falling.

This paper estimates the public and private sector wage gap trend from 2000 to 2014 using 'Korean Labor and Income Panel Study.' We account for unobserved fixed effect by using 1st differencing log wage in order to allow the gap to vary over time. Standard OLS estimates present the public sector wage is 10% higher than private sector on average. Moreover, the public sector wage premium displays the inverted V shape: sharply increasing up to 2006 and decreasing from 2007 to 2014. However, after controlling unobserved fixed effect, the public sector wage premium disappears and does not display the inverted V shape any more.

Purpose: This descriptive study was to investigate the quality of life in patients with hematopoietic stem cell transplantation (HSCT) from June 1 to October 13, 2007. Method: The survey was conducted in 6 different university hospitals which located in Seoul and Jeollanam-do province using the Functional Assessment of Cancer Therapy-BMT Scale (FACT-BMT) version 4. We collected a total of 155 questionnaires and analyzed 149 among them. Results: The average score of quality of life was 2.53 out of 5. Physical well being score was highest among sub-domains, followed by emotional well-being, additional concerns, social/family well-being, and functional well-being. Study subjects worried that their conditions would get worse. However study subjects didn't regret having been received HSCT. Age, duration from HSCT, age at diagnosis, income, readmission, HSCT type, educational background, marital status, and the level of activities of daily living were related to quality of life. Conclusions: The findings of this study indicates that the HSCT survivor's quality of life issue is still important and have to be investigated repeatedly in the future. That is necessary for generalizing QOL outcomes for clinical use. We also suggest to develop interventions to improve QOL.

As intensifying competition alters the dynamics of the wireless industry and carriers begin to tap out traditional subscribers-business users and early adopters-wireless operators have come under pressure to begin expanding their target subscriber base. While alternative market segments such as youths, senior citizens, and lower-income or credit-challenged customers often offer less compelling fundamentals (i.e., lower average revenue per user and higher churn rates), carriers, in their race to increase market share, can no longer overlook these potential market segments. In particular, the youth market is a very appealing market segment for carriers to focus on for several reasons. Carriers in many parts of the world have already begun recognizing the compelling advantages of concentrating on youths and teens. This paper will examine the dynamics of the youth/teen population and what attributes make this group an appealing market for wireless carriers. In addition, it will take a look at new emerging technologies that may help carriers attract the youth market especially mobile data, entertainment applications, and wireless messaging. This paper also studies the sensation that carriers in Europe and Japan are achieving with the youth population and suggests how carriers in Korea can emulate that success.

Recently, as the income level and quality of life have improved, the desire for a pleasant environment has increased, and a deodorization plan is required through thorough prevention and diffusion of odorous substances in waste treatment facilities recognized as hateful facilities, appropriate collection, and selection of the right prevention facilities. In this study, a waste disposal facility was modeled and computerized analysis for odor and ventilation analysis was conducted. Numerical analysis of the waste treatment facility was performed at the size of the actual plant. CATIA V5 R16 for numerical model generation and ANSYS FLUENT V.13 for general purpose flow analysis were used as analysis tools. The average air-age of the internal was 329 seconds, and the air-flow velocity was 0.384m/s. The odor diffusion analysis inside the underground pump room showed congestion-free air circulation through streamline distribution and air-age distribution. This satisfies the ASHRAE criteria. In addition, the results of diffusion analysis of odorous substances such as ammonia, hydrogen sulfide, methyl mercaptan and dimethyl sulfide were all expected to satisfy the regulatory standards. Particularly in the case of the waste loading area, the air-flow velocity was 0.297m/s, and the result of meeting the regulatory standards with 0.167ppm of ammonia, 0.00548ppm of hydrogen sulfide, 0.003ppm of methyl mercaptan, and 0.003ppm of dimethyl sulfide was found.
