Mobile marketing is a brand new phenomenon. In Malaysia, marketeers do not seem to understand well enough the perceptions of consumers according to mobile marketing, especially to the mobile service users. This study analyses and evaluates any significant relationship between consumer perceptions and intentions with respect to mobile marketing, and seeks to determine the expectations, preferences, pattern and usage of the consumers of Mobile Marketing Product and Service (MMP&S). The data was obtained by convenience sampling in the big cities of Malaysia. A total of 500 questionnaires were distributed and a sample of 112 usable questionnaires was selected. The result of this research applying the Technology Acceptance Model (TAM) point to the fact that perceived usefulness, perceived ease of use, perceived innovative, social influence have a direct positive relationship with the intention to use mobile marketing. This, in turn, can shed light on the main factors determining consumer intentions to use mobile marketing that may control consumer adoption of mobile marketing.

The ritual for community is a group ritual performed by the regional community of a village for the safety of the residents and abundant harvests. However, many ritual places have been destroyed by the anti-superstition movement, New Community Movement (Saemaul Movement), industrialization and urbanization since the 1960s. Under the circumstances, this study researched the status of use of the ritual place in Beommul-dong in Daegu where the ritual was revived in 2004 after having been suspended since the end of the 1980s due to urbanization. The revival of the ritual for community in Beommul-dong in Daegu, which had been maintained by the village people alone, is the prime example of the vitalization of local community as the recreation of local community, since the ritual has been transformed into a kind of festival involved with and financed by the local government. The study on analyzing the usage pattern of the ritual place may provide useful sources to come up with the modernized functions of the ritual place as a community place, where the heads of the ward office and cultural center, lawmakers and most of the residents perform the ritual, share foods and tread on the God of the Earth across the village at 11:30 in the morning on every January 16 of the lunar calendar.

Consumer citizenship is essential for better market and economy, and social capital plays an important role for raising consumer citizenship. This study explored the types of social capital developed on social media, and investigated the relationship between consumer citizenship of college students and social capital. Using data from 263 undergraduate students currently using social media, K-mean cluster analysis, one-way ANOVA, Duncan's multiple range test, chi-squared test, and multiple regression analysis were conducted. The major results were as follows. First, four types of social capital on social media were identified: mediocre social capital, instrumental-centered social capital, weak social capital, and strong social capital. Second, socio-demographic characteristics variables such as gender and work experience showed significant difference by type of social capital through social media. In addition, the most used social media and time for using social media variables showed significant difference by type of social capital through social media. Third, controlling for socio-demographic characteristics and social media usage pattern, the types of social capital had a significant effect on consumer citizenship. Based on the results, the implications for consumer education to develop consumer citizenship were suggested.

The purpose of this study is to provide suitable outdoor spaces for Korean elderly, examining characteristics and types of existing outdoor spaces and presenting design guideline of outdoor space for elderly. To do this, this study examined previous research papers and scholastic writings, related to elderly housing, and analyzed twelve cases of elderly housing complex. Additionally evaluation of usage pattern and physical trace carried out on twelve cases. As a result, first, the study showed that outdoor spaces for elderly were classified 5 types; entrance area of housing complex, building entrance area, outdoor living area, in & outdoor neutral area, and parking lots. Outdoor living area is subdivided into residents' public space, green space, health & sports space and landscape space. Characteristics of outdoor space are deeply related to safety, amenity, recognition and efficiency. Second, types of outdoor space in elderly facilities are very limited in verity, just facilitating with rest space, sport space, and garden space. Third, from a standpoint of barrier-free-design, twelve cases are not carefully concerning about outdoor space for elderly.

The implementation of abnormal behavior detection IDS is more difficult than the implementation of misuse behavior detection IDS because usage patterns are various. Therefore, most of commercial IDS is misuse behavior detection IDS. However, misuse behavior detection IDS cannot detect system intrusion in case of modified intrusion patterns occurs. In this paper, we apply data mining so as to detect intrusion with only audit data related in intrusion among many audit data. The agent in the distributed IDS can collect log data as well as monitoring target system. False positive should be minimized in order to make detection accuracy high, that is, core of intrusion detection system. So We apply data mining algorithm for prediction of modified intrusion pattern in the level of audit data learning.

In many parts of the world, low cost housing used to be built and maintained by the governments, based on designs and detail specifications prepared by the public sector with construction carried out by contractors. Results vary due to differences in design standards, workmanship and property management, depending also on the neighbourhood's care of the estates and their pattern of usage. In the UK, where Private Finance Initiative (PFI) has been used for infrastructure projects, there have been successful cases of city estate being transformed by PFI. These PFI housing schemes involve new-build, refurbishment as well as facility management. Unlike traditional construction, which is based on prescriptive specifications, PFI housing is based on output specifications. A study has been undertaken to compare the two specification approaches as they are applied to housing estate. Results are enlightening and serve as good reference to cities such as Hong Kong SAR and Singapore, where public housing provisions have been a major concern of their citizens as the building stock gets older.

In ASIP design, compiler is required for performance evaluation of processors being designed. The design of machine specific compiler is time consuming. This paper presents the system which generates C compiler from MDL descriptions. Compiler generation using MDL can support user retargetability and concurrency between compiler design and processor design. However, it must overcome semantics gap between compiler and machine. To handle this problem, the proposed system maps behavioral descriptions to library which contains abstract behavior for each tree pattern. Using mapped instructions and information on register file usage, the proposed system generates back-end interface function of the compiler. Generated compilers, for MIPS R3000, ARM9 cores, have been proved by application programs written in C code.

In this paper, we introduce a modulation code design problem where best selection of two-dimensional codewords are determined to reduce two-dimensional (2D) intersymbol interference (ISI) and interpage interference (IPI). Codeword selection problem is formulated as a quadratic integer programming model that minimizes intra- and inter-symbol differences subject to uniform symbol usage and minimal Hamming distance violations. Second integer programming model detects the occurrence of isolated pixel pattern in the selected codewords. The proposed models are applied to 4-level and 2-level 6/8 codes.

A material mixing method to obtain an optimal topology for a structure in a thermal environment was suggested. This method is based on Evolutionary Structural Optimization(ESO). The proposed material mixing method extends the ESO method to a mixing several materials for a structure in the multicriteria optimization of thermal flux and thermal stress. To do this, the multiobjective optimization technique was implemented. The overall efficiency of material usage was measured in terms of the combination of thermal stress levels and heat flux densities by using a combination strategy with weighting factors. Also, a smoothing scheme was implemented to suppress the checkerboard pattern in the procedure of topology optimization. It is concluded that ESO method with a smoothing scheme is effectively applied to topology optimization. Optimal topologies having multiple thermal criteria for a printed circuit board(PCB) substrate were presented to illustrate validity of the suggested material mixing method. It was found that the suggested method works very well for the multicriteria topology optimization.
