Cities developed by prosperity of industrial activities are inflated due to the rapid influx of the urban population. In the process, their structure was reorganized with overall urban redevelopment methods. As the a results from the propulsion of overall redevelopment plan, the city environment exposed uniform urban landscapes, absence of sense of place for permanent abodes and other urban problems. At the beginning of the 21st century, people with introspections on the problems focused their attention on making their places attractive using their place's unique identity so that people could feel like to stay there for a long time. They tried to regenerate buildings and cities while still maintaining spatial and historical context of their living environment. This study looks into the regeneration of Shikumen Linong House as a fine example of such a redevelopment in order to provide with a practical resource for urban redevelopment plans in Korea. The study in the first content examines the formation processes of the city of Shanghai as the gateway of the modern China. In the second, it looks into the formation processes and characteristics of Shikumen Linong House in the Xintiandi complex between 1920 and 1930's. In the end, it analyses spatial and formational characteristics and the applied dwelling regeneration method for the of Shikumen Linong House in the Xintiandi complex.

Students' protocols obtained from think-aloud interviews were analyzed in the aspects of the success at first two problem-solving stages (understanding and planning), the time to complete a problem, the time at each problem-solving stage, the number of transition, and the transition rate. These were compared in the aspects of the context of problem, the success in solving problem, students' logical reasoning ability, spatial ability, and learning approach. The results were as follows:1. Students tended to spend more time in everyday contexts than in scientific contexts, especially at the stages of understanding and reviewing. The transition rate during solving a problem in everyday contexts was greater than that in scientific contexts. 2. Unsuccessful students spent more time at the stage of understanding, but successful students spent more time at the stage of planning. 3. Students' logical reasoning ability, as measured with the Group Assessment of Logical Thinking, was significantly correlated with the success in solving problem. Concrete-operational students spent more time in completing a problem, especially understanding the problem. 4. Students' spatial ability, as measured with the Purdue Visualization of Rotations Test and the Find A Shape Puzzle, was significantly correlated with their abilities to understand a problem and to plan for its solution. 5. Students' learning approach, as measured with the Questionnaire on Approaches to Learning and Studying, was not significantly correlated with the success in solving problem. However, the students in deep approach had more transitions and greater transition rates than the students in surface approach.

Purpose - The exhibition is one of the critical distribution channels that leads to mass sales of products. Servicescape is considered as an effective means facilitating consumers' purchasing behavior. The objective of this research is to examine the effects of servicescape of the exhibition on consumer's purchasing behavior measured by time spent, the number of consultations, the number of items purchased, and amount of money spent. Research design, data, and methodology - Servicescape was divided into four main components: 'spatial layout/functionality', 'ambient condition', 'design/artifacts', and 'human factor'. Based on previous studies, this study hypothesized that servicescape dimensions first influence consumer's shopping duration and the number of consultations which in turn, affects consumer's actual purchase. A total of 407 samples were collected from attendees in Baby Expo taken place in Kyunggido, South Korea. The data were used to assess overall fit of the proposed model and test hypotheses using structural equation modeling. All the constructs had acceptable levels of composite reliability and convergent and discriminant validity. Results - The results showed that except for 'spatial layout/functionality', all components of servicescape had a significant influence on consumer's shopping duration in the exhibition. Except for 'design/artifacts', other factors of servicescape did not show a significant effect on 'the number of consultations'. Interestingly, 'design/artifacts' exerted a significant negative effect on 'the number of consultations'. As expected, 'time spent' and 'number of consultations' showed significant effects on both 'the number of items purchased' and 'amount of money spent'. Conclusions - The results offer some insights into the effect of servicescape on facilitating consumers' purchasing behavior in the context of the exhibition. Theoretically, this study provides a new type of conceptual framework that verifies the relationships between not only servicescape and purchasing behavior, but also purchasing behavior-related variables. In addition, this study supports the concept of a dark side of servicescape. With regards to practical implications, this study suggests that exhibition organizers should put more efforts in facilitating consumer's desire to stay. More importantly, organizers need to keep in mind that excessive emphasis on 'design/artifacts' to increase consumers' shopping duration can cause a side effect that reduces opportunities for interactions with customers.

The seasonal and spatial diversity of picocyanobacteria (Pcy) in lakes of the Great Mazurian Lakes (GLM) system was examined by DGGE analysis of molecular markers derived from the 16S-23S internal transcribed spacer (ITS) of the ribosomal operon and the phycocyanin operon (cpcBA-IGS). The study of nine lakes, ranging from mesotrophy to hypereutrophy, demonstrated seasonal variance of Pcy. The richness and Shannon diversity index calculated on the basis of both markers were higher in spring and lower in early and late summer. No statistically significant relationships were found between the markers and trophic status of the studied lakes or Pcy abundance. There were, however, statistically significant relationships between the diversity indices and sampling time. The analysis pointed to a different distribution of the two markers. The ITS marker exhibited more unique sequences in time and space, whereas a greater role for common and ubiquitous sequences was indicated by the cpcBA-IGS data. Examination of the Pcy community structure demonstrated that communities were grouped in highly similar clusters according to sampling season/time rather than to the trophic status of the lake. Our results suggest that time is more important than trophic status in shaping the diversity and structure of Pcy communities. The seasonal changes in picocyanobacteria and differences in diversity and community structures are discussed in the context of well-established ecological hypotheses: the PEG model, intermediate disturbance hypothesis (IDH), and horizontal gene transfer (HGT).
