In data mining, having access to large amount of data sets for the purpose of predictive data does not guarantee good method, even where the size of Real data is Mobile commerce unlimited. In addition to searching expected Goods objects for Users, it becomes necessary to develop a recommendation service based on XML. In this paper, we design the optimized XML Recommender product data. Efficient XML data preprocessing is required, include of formatting, structural, and attribute representation with dependent on User Profile Information. Our goal is to find a relationship among user interested products from E-Commerce and M-Commerce to XDB. Firstly, analyzing user profiles information. In the result creating clusters with analyzed user profile such as with set of sex, age, job. Secondly, it is clustering XML data which are associative products classify from user profile in shopping mall. Thirdly, after composing categories and goods data in which associative objects exist from the first clustering, it represent categories and goods in shopping mall and optimized clustering XML data which are personalized products. The proposed personalized user profile clustering method has been designed and simulated to demonstrate it's efficient.

A method for generating 3D solid models and drawings for a rotor in the steam turbine is proposed. One of the most important design steps is generating the drawing for manufacturing it. This step is a very routine and time-consuming job because each drawing is composed of several kinds of views and many dimensions. To achieve automation for this activity, rotor profiles are composed of 2D entity groups with attributes. Based on this, the improved design process is developed as follows. First, the rotor profiles can be selected by searching for 2D entity groups using the related attributes. Second, the profiles are connected sequentially so that an entire rotor profile is determined. The completed profile is used to generate 2D drawings automatically, especially views, dimensions, and 3D models. The proposed method is implemented using a commercial CAD/CAM system, Unigraphics, and API functions written in C-language and applied to the rotor of steam turbines. Some illustrative examples are provided to show the effectiveness of the proposed method.

Those studies in the field of Management Information Systems and the Success Model of the DeLone and McLean's Information Systems suggest that some factors related to information systems should be developed and operated to affect the performance of the user's personal and companies through the introduction and use of corporate information systems. The purpose of this study is put on searching for some factors which impact on user satisfaction about the customer information management systems of call center. We did conduct on a survey of 539 people who are working as a call center counseling employees as setting up a structural equation model which reflects previous research on working environment and job satisfaction, and modified DeLone and McLean's information system success model. The results of this study are as follows. First, seven of the eleven hypotheses that three quality of the information systems might be affecting working environment, job satisfaction, user satisfaction were adopted Second, we confirmed that the working environment works as a the partial mediation and the quality of services works as a fully mediation between system/information quality and users' satisfaction. The implications of this study are that it is necessary not only to make a good working environment but also to keep improving it in order to boost the operational performance of information systems in the future.

The purpose of this study was to examine in influence on the effect of understanding their major and career self-efficacy on career indecision of the community college students majoring in fashion and is intended to provide useful resources on career education and guidance of students through this research. In order to achieve the objective of study, 349 college students in Gyeonggido were selected for the questionnaires for the understanding major, career self-efficacy, and career indecisions survey. The survey data was analyzed using the statistical program SPSS 12.0 and this was followed by the descriptive statistics, factor analysis, and hierarchical regression analysis. The results were as follows; First, career indecision factors of the college students majoring in fashion were extracted 5 valuables that were 'insufficiencies vocational information', 'an undeceivable character', 'the lack of self well-defined', 'the lack of needs for job' and 'external barrier for the career'. Second, the subordinate valuables of understanding major which is 'social cognition for the major', 'satisfaction on the major course', and 'satisfaction on the major skill', had positive effect on career self-efficacy. Third, understanding of major and the subordinate valuables of career self-efficacy which is 'making goal for the career', 'career information', 'career plan for the future', 'alternative searching', and 'overcoming difficulties' had negative effect on career indecision. Forth, understanding major and career self-efficacy had medicated in career indecision.

The purpose of this study is to examine how the perception of lives and studies in the Joseon Dynasty period, and the concept of its sculptures can be reflected in Korean traditional pavilion place, from the perspective of Nomadism as a western philosophy of this era. Nomadism literally refers to way of life of peoples who do not live continually in the same place but move cyclically searching for temporary centres whose stability depends on the availability of food and water supply or pastures for their livestock. In recent years, the term encompasses three general types: job nomads, digital nomads and ubi-nomads, which represent distinct features of modern society. Its concept implies looking for the new creative possibility through the liberation of desire and the breakaway to another thinking through continuous formation and transformation. Likewise, Korean traditional pavilion is the architecture to take a quick rest while walking in the mountains. This open place thus connects surroundings with people who are allowed to assimilate with nature as well as train their mind by following the law of nature, in order to finally reach the celestial state of mind. Knowing how to see, enjoy and appreciate the arts very close to nature, our ancestors were able to learn aesthetic activities. After recognizing Korean traditional pavilion as the potential place of unification of heaven and men which is Korean scholor's lifestyle and outlook on the world, this study accordingly will identify the value and meaning of Korean traditional architecture according to Nomadism in the occidental point of view.

Measuring magnetic fields with a SQUID sensor always requires preliminary adjustments such as optimum bas current determination and flux-locking point search. A conventional magnetoencephalography (MEG) system consists of several dozens of sensors and we should condition each sensor one by one for an experiment. This timeconsuming job is not only cumbersome but also impractical for the common use in hospital. We had developed a serial port communication protocol between SQUID sensor controllers and a personal computer in order to control the sensors. However, theserial-bus-based control is too slow for adjusting all the sensors with a sufficient accuracy in a reasonable time. In this work, we introduce programmatic control sequence that saves the number of the control pulse arrays. The sequence separates into two stages. The first stage is a function for searching flux-locking points of the sensors and the other stage is for determining the optimum bias current that operates a sensor in a minimum noise level Generally, the optimum bias current for a SQUID sensor depends on the manufactured structure, so that it will not easily change about. Therefore, we can reduce the time for the optimum bias current determination by using the saved values that have been measured once by the second stage sequence. Applying the first stage sequence to a practical use, it has taken about 2-3 minutes to perform the flux-locking for our 37-channel SQUID magnetometer system.

People live in their everyday life busy with studies, part-time jobs, and searching for an ideal job. In their busy routine, they try to find time for themselves and expose their emotions through diverse social network services(SNS). We made a service that we can plant a virtual tree in places we daily visit and go by. You can keep note on the virtual tree and look through the past records. It is a reality based mobile application service that can be used like a diary.In this project we chose the tree as the metaphor and tried to express time passing in a specific place. As our memory is a part of our daily life, we emphasized the meaning of space important.
