For the Han-river estuary and DMZ where white-naped crane (Grus vipio; endangered migratory bird) stopover or spend winter, the habitat composition and the habitat use pattern of white-naped crane were analyzed with the position data obtained by the satellite tracking method. By the use of geographic information system (GIS), the percent composition of seven habitat categories of white naped-crane data points (n=228) was analyzed. The chi-square test showed that the white-naped crane habitat use pattern was significantly different (p<0.05) from that of random points (n=228). It means that white-naped crane select and use particular habitat area in the Han-river estuary and DMZ.

This study explores the major factors that are likely to affect the acceptance and resistance of innovative products and services. The TAM (Technology Acceptance Model) has been widely used for understanding consumer acceptance of new technology. This model displays perceived usefulness and perceived ease of use as antecedents of intention to adopt and use. However, research has reported a variety of preceding variables for technology acceptance. In addition, considering paradoxes of technology, research regarding both acceptance and resistance in an integrated model can explain consumer perception and behavior in detail. The results of this study states that relative benefits, degree of innovation in technology, perceived usefulness and perceived ease of use have had positive influence on the intention to adopt but negative impact on that of resistance. However, alterations of usage and perceived risk positively affects resistance, but also have negative effects on the intention to adopt. Finally, intention to adopt has comparatively greater influence than that of resistance on intention to use. Theoretical and managerial implications of the results are also discussed.

Groupware technologies have become an important part of the business computing infrastructure in many organizations, but many groupware applications, especially those requiring significant collaboration among users, are still nut adequately used. The purpose of the paper is to explore the impact of groupware on the job performance. Recently, utilization of new information technology such as groupware can increase office productivity, but often this potential is not realized. Results of most studies indicate that groupware could increase the productivity of knowledge workers, who compose the majority of the labor force in the organization. The study on the impact of job characteristics on groupware and job performance is not sufficient. This study examines the influence of job characteristics such as job diversity, autonomy, and feedback on the use of groupware and job performance. In addition to that, this study examines the influence of the use of groupware on job performance. The results of regression analyses revealed that feedback was the major predictor of job performance, while autonomy and job diversity were the Haler predictors of the use of groupware. Also, the use of groupware were found to be important predictors of job performance.

This study was examined empirically the relationship between exogenous and endogenous variables to use internet shopping malls. Exogenous variables in our model are retrieval simpleness, quality of order treatment, web reputation, update and system quality and endogenous variables are perceived usefulness, perceived ease of use and intention of using internet shopping malls. The results of the path analysis are shown as follows. All exogenous variables have a direct effect on perceived ease of use while both retrieval simpleness and update has a direct effect on perceived usefulness. The perceived ease of use has a direct effect on the intention of using internet shopping malls and has a indirect effect on the intention through perceived usefulness. Especially, web reputation among the exogenous variables has the strongest impact on the perceived ease of use and retrieval has the strongest impact on the perceived usefulness.

Purpose: In this study the impact of pro-environmental behavior, well-being oriented behavior, and use of cloth menstrual pads on dysmenorrhea in Korean female adults was examined according to the theory of reasoned action. Methods: A cross-sectional study was conducted with 195 Korean female adults. Data were collected from June to August, 2010 using self-report questionnaires. Data were analyzed using t-test, one-way ANOVA, Pearson correlation coefficients, multiple regression, and logit regression with STATA 10.0. Results: Pro-environmental behavior explained 48% of well-being oriented behavior. Well-being oriented behavior explained 10% of cloth pad use. Use of cloth pad explained 4% of dysmenorrhea and 5% of menstrual pain. The path through well-being oriented behavior had a significant effect from pro-environmental behavior to cloth pad use. Conclusion: Use of cloth pad was significantly related with well-being oriented behavior, pro-environmental behavior, social influence, dysmenorrhea, and menstrual pain. The results of this study suggest that pro-environmental strategies can help health care providers diminish clients' menstrual symptoms. Nursing intervention can support pro-environmental behavioral strategies.

Use impacts to trail and campground deteriorations and their changes of natural environment were studied in Mt. Kaya National Park in 1989. The entire width, bare width and maximum depth of trail as the trail condition were significantly greater on the more heavily used trail. Deteriorations of trail which were surveyed at the total of 51 were significantly different from those of non-deteriorated points. The changes of soil and vegetation of trailsides were not found at a uniform tendency but could be more clearly grouped by the types of user's disturbance, and use impact on trailside had reached 15m inside of forest. Percentage of area for Class 5 in campsite was about 36% and about 69% of campsite area was more severe than Class 3. Recreational activities retarded the diameter growth of trees in campsite and accelerated the different composition of species. Soil and vegetative factors adapted to understand the difference of use amount and the realm of use impact could be sorted. The realm influenced by user's disturbance was about 50m from the core of campsite. Fraxinus rhynchophylla, Rhus trichocarpa, Symplocos chinensis for. pilosa and Stephanandra incisa were considered as the tolerant species to user's impact.

The design of a museum mobile application's user experience demands an in-depth comprehension of the user experience dimensions and the unique attributes of the user experience elements that users may encounter. This paper through a series of experimental studies and analyses of experiences related to the use of museum mobile applications, derives a user experience framework consisting of four dimensions and 19 elements, which has been verified for feasibility. The study shows that all four dimensions have a positive impact on user satisfaction, but the degree of impact varies. Among them, emotionality of use and ease of use have the greatest impact, while usefulness of use and multiformity of function have relatively less impact. In addition, the user experience of museum mobile application can also positively influence the user's future intention to recommend, continue using, and even the actual visit to the museum.

This paper discusses several topics associated with the densification caused by supertall buildings and their impact on city systems. The paper covers five key areas where a supertall tower creates a concentration of needs and effects. First, the paper comments on population shifts towards the city and how they affect carbon footprint, utilities infrastructure and transport. The effect of single- and mixed-use towers is discussed in the context of population density. The second section brings the issues of transit, accessibility and master planning into focus. The use and criticality of public transport, cycling and walking is described. Servicing and deliveries using freight consolidation and shared systems is also discussed along with their contribution to the culture of sustainable travel. In the third section the paper reflects on supertall buildings' below-ground utilities and drainage provision, particularly the challenges faced in established city infrastructures. The utilities issues associated with supertall concentration (in land-use terms) compared to equivalent low-rise distribution is also commented on in the context of surface water runoff. In the fourth section, the topic of supertall sustainability is discussed and how city systems need to respond to create desirable and affordable space for occupiers. The changing need for vertical communities, 'stacked neighbourhoods' and the notion of a micro-city is described. Finally, the paper considers the energy consumption and resilience of supertall buildings in the context of basic geometry, façade design, climate and mixed-use benefits as they impact city systems.
