Improving public awareness of wood is crucial for expanding the use of wood and establishing a wood culture. In this study, the environment and trends of the public's wood utilization were analyzed using a questionnaire survey and online text mining at a time when eco-friendly practices are gaining popularity. As a result of reducing climatic and environmental concerns and its positive physical and psychological effects, the use of wood is predicted to rise in areas intimately connected to everyday living, such as wood furniture, wooden structures, and interior materials. Nonetheless, there was a negative awareness that wood was expensive, difficult to maintain, and associated with deforestation. The correlations between wood-related search terms on major Korean portal sites were analyzed and categorized into five groups: Wooden architecture, cultural education, woodworking, wood industry, and wood policy. As a building material, wood was seen as more traditional and friendly than reinforced concrete and stone. Eighty-six percent of respondents expected to utilize wood as a building material in the future, regardless of whether the wood is domestically produced or imported. Sixty-five percent responded favorably about the effects of wood on the health of wooden home inhabitants. It is believed that both active publicity and quantifiable value analysis of human and environmental friendliness are required to increase pro-environment awareness of wood utilization.

Despite of continuous efforts to crack down on piracy using penalties and regulations, this unauthorized piracy market is still enormous. Since the moral hazard about this phenomenon is pervasive and continually upsets the major intellectual property markets, an alternative plan is required. The purpose of this study is to provide an objective insight for factors that affect people's digital video piracy behavior. The following two research propositions were the focus: what psychological factors affect piracy behavior and how are these factors related to one another? In order to accomplish the research aims, we reviewed literatures on the current state of piracy in South Korea, characteristics of digital contents, studies on criminal psychology and behavioral theories. Previous research in the fields of criminal theory indicated that neutralization, a form of rationalization, would help explain digital piracy intentions. Thus, this study developed a model that explains effects of neutralization techniques and tested the possibility of an integrated model with other behavioral theory such as TPB and TIB. Empirical results of the study(368 sample collected) showed that all the factors in TPB including Attitude to Piracy(+), Subjective Norm(-), Perceived Behavioral Control(+) had a significant impact on Piracy Intention. Moreover, two neutralization techniques, Condemn the Condemners(+) and Appeal to Higher Loyalties(+), had a significant effect on Piracy Intention. In addition, Past Behavior had strong impacts on Attitude(+), Perceived Behavioral Control(+) and Piracy Intention(+). In terms of Expected Profit, it had an impact on Attitude to Piracy positively. These findings suggest implications for protecting the current intellectual property markets, with many stakeholders in movies and media industries. There are some limitations as followed: first, the study did not consider other neutralization techniques, low level of deterrence and the other expected results despite the possibility of their effects. Second, the study needs improvements through longitudinal research because the cross-sectional research could not rule out the alternative explanations.

Long span bridges such as steel cable stayed and suspension bridges are usually more flexible than short to medium span bridges and expected to have large deformations. Deflections due to live load for long span bridges are important since it controls the overall heights of the bridge for securing the clearance under the bridge and serviceability for securing the comfort of passengers or pedestrians. In case of sea-crossing bridges, the clearance of bridges is determined considering the height of the ship master from the surface of the water, the trim of the ship, the psychological free space, the tide height, and live load deflection. In the design of bridges, live load deflection is limited to a certain value to minimize the vibrations. However, there are not much studies that consider the live load deflection and its effects for long span bridges. The purpose of this study is to investigate the suitability of live load deflection limit and its actual effects on serviceability of bridges for steel cable-stayed and suspension bridges. Analytical study is performed to calculate the natural frequencies and deflections by design live load. Results are compared with various design limits and related studies by Barker et al. (2011) and Saadeghvaziri et al. (2012). Two long span bridges are selected for the case study, Yi Sun-Sin grand bridge (suspension bridge, main span length = 1545 m) and Young-Hung grand bridge (cable stayed bridge, main span length = 240 m). Long-term measured deflection data by GNSS system are collected from Yi Sun-Sin grand bridge and compared with the theoretical values. Probability of exceedance against various deflection limits are calculated from probability distribution of 10-min maximum deflection. The results of the study on the limitation of live load deflection are expected to be useful reference for the design, the proper planning and deflection review of the long span bridges around the world.

Objective : Obesity in modern society has a significant impact on pathological, psychological and social problems. Therefore, many studies on obesity treatment using herbal extracts with fewer side effects have been conducted. This study was designed to investigate the effect of inhibiting fat accumulation in vitro in order to Mongolian medicinal plants find anti-obesity candidate among. Methods : We measured pancreatic lipase inhibitory activity in Mongolian medicinal plants extract. Cytotoxicity of these extracts was monitored in 3T3-L1 cells by MTT assay. In addition, the anti-obesity effects was confirmed at concentrations of 0.2, 0.1 and 0.05 mg/㎖ through Oil red O staining. Results : Among Mongolian medicinal plants, Rheum undulatum roots in September (RURS), Paeonia anomala L. (PAL), and Fragaria orientalis (FO) showed the highest pancreatic lipase inhibitory activity. As a result of the MTT assay, more than 80% was judged to be non-toxic, and the concentration was determined, and as a result of evaluating the lipid accumulation inhibitory effect, 6 types were selected as candidates. Conclusion : Based on these results, the top 7 species expected to be used as anti-obesity functional materials were selected. However, additional efficacy verification and mechanism of action need to be established in the future. So, it is expected that the medicinal plants verified through this will be used as functional materials for the prevention and treatment of obesity.

The present study was initially designed to figure out the general condition of care giving system for the elderly women who need long term care and the level of their depression according to the conditions of care. And This research is intented to present appropriate policy that could help the establishment of supporting system for the fragile elderly women.1 used the data from <2001 National Study on the Needs for the Long-Term Care Elderly> by Korea Health and Population Institute. The results are as follows: First, Two third of all the respondents had serious problems (2-9 activities limits) in Instrumental Daily Living Ability(DAL). Most respondents reported “low” in satisfaction level related to receiving care, meaning the elderly had negative perception for the care from the family. The elderly expected their children to be as the primary care giver and mostly wanted to live with them in the future. Second, The majority of the long term care elderly women haven't used community service facilities very often and said they are not likely going to use the facilities in the future. Third, The respondents reported high in depression level as to lower satisfaction with their children's support, poorer health condition, more reluctant to use service facilities due to the cost, and fewer friends and neighbors resources around them. Therefore I could say that negative factors for the elderly women's psychological health were having unsatisfactory relationship with intimate people, developing physical illness, being in economic difficulties. That is, receiving less help from close family members, shrinking social network, and experiencing economic hardship would have negative effects on elderly women's psychological health. In the basis of these results, I suggest that in the mean time we shouldn't overlook the importance of the private support when we develop the public elderly support system.

Purpose - Before the year 2000, the housing prices in Korea were increasing every decade. After 2000, for the first time, Korea experienced a decrease in housing prices, and the repetitive cycle of price fluctuation started. Such a "boom and bust cycle" is a worldwide phenomenon. The current study proposes a mathematical model to explain price fluctuation cycles based on the theory of consumer psychology. Specifically, the model incorporates the effects of buyer expectations of future prices on actual price changes. Based on the model, this study investigates various independent variables affecting the amplitude of price fluctuations in housing markets. Research design, data, and methodology - The study provides theoretical analyses based on a mathematical model. The proposed model uses the following assumptions of the pricing mechanism in housing markets. First, the price of a house at a certain time is affected not only by its current price but also by its expected future price. Second, house investors or buyers cannot predict the exact future price but make a subjective prediction based on observed price changes up to the present. Third, the price is determined by demand changes made in previous time periods. The current study tries to explain the boom-bust cycle in housing markets with a mathematical model and several numerical examples. The model illustrates the effects of consumer price elasticity, consumer sensitivity to price changes, and the sensitivity of prices to demand changes on price fluctuation. Results - The analytical results imply that even without external effects, the boom-bust cycle can occur endogenously due to buyer psychological factors. The model supports the expectation of future price direction as the most important variable causing price fluctuation in housing market. Consumer tendency for making choices based on both the current and expected future price causes repetitive boom-bust cycles in housing markets. Such consumers who respond more sensitively to price changes are shown to make the market more volatile. Consumer price elasticity is shown to be irrelevant to price fluctuations. Conclusions - The mechanism of price fluctuation in the proposed model can be summarized as follows. If a certain external shock causes an initial price increase, consumers perceive it as an ongoing increasing price trend. If the demand increases due to the higher expected price, the price goes up further. However, too high a price cannot be sustained for long, thus the increasing price trend ceases at some point. Once the market loses the momentum of a price increase, the price starts to drop. A price decrease signals a further decrease in a future price, thus the demand decreases further. When the price is perceived as low enough, the direction of the price change is reversed again. Policy makers should be cognizant that the current increase in housing prices due to increased liquidity can pose a serious threat of a sudden price decrease in housing markets.

Purpose. to help them find mental rest and improve school life adjustment by way of a fine art cure program. Methods. two primary schools in Gyeongsangnam-do were chosen where there are plenty of multiple-family kids. 13 children from the families between Korean husbands and foreign wives were divided into 2 groups: experimental group (7, C School), control group (6, H School). The two groups took the KSD (Kinetic School Draw), while the experimental group received a fine art cure program (40 minutes, once a week, 10 times in total). After the program, the KSD was given again to both groups. To prove the effects of this study, the picture projection test KSD was given before and after the experiment. For comparison and analysis, the changes in each individual's attitude, behavior, responses, and emotions were observed and recorded. Results. The fine art treatment program had some effects on the psychological rest of the elementary school children from multiple-culture families. In the pretest before the art cure program, the subjects shrank and cared a lot about others. According to the progress of the program, however, their worries and anxiety began to be gone. They had confidence through mental ease and self-respect. Therefore, the fine art cure program had a positive effect on the improvement of self-respect and sociality of multiple-culture family kids. Their school life was influenced by the newly-attained confidence, achievement, and peer relationship. Conclusions. This research is of some significance in that the fine art cure program was held to reveal its effects on the school life adjustment of the elementary school kids from multiple-culture families, especially because worries grow about the possibility of their maladjustment in the era of multiple-culture families. In addition, this program is expected to give some basic information about the development of programs to make friendly relations and smooth communication among the multiple-culture parents and teachers as well.
