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.

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.

This research classified fashion merchandisers into different categories depending on the type of companies they worked for and inquired into their line of work. In so doing, the authors attempted to outline the work for merchandise mix performed by each type of merchandiser and provide some raw data, which can be utilized to enhance their work efficiency. The evaluation tool used for this study was the questionnaire made on the basis of preceding studies, literature, and trade journals, which was then modified through one on one interviews with fashion merchandisers. The questionnaire contained 15 questions about merchandise mix. For data analysis, SPSS Package Program was used to conduct frequency analysis, ANOVA, and Tukey's test. The findings are as follows 1. National brand merchandisers spent most time on merchandise planning, then department store buyers, followed by imported brand merchandisers, and lastly buying office merchandisers. 2. In merchandise planning, National brand merchandisers did more work overall compared to other merchandisers. In production planning, buying office merchandisers spent more time than any others on searching for new suppliers and decision-making. 3. Production planning took up a greater portion of their work for National brand merchandisers and buying office merchandisers compared to department store buyers and imported brand merchandisers. 4. Imported brand merchandisers spent more time on purchase planning and actual purchase compared to any others.

본 논문에서는 증강현실 기반 일상다이어리 어플리케이션 서비스를 기획하였다. 제안하는 어플리케이션을 통하여 사용자는 시간이 흐른 뒤에도 변함없이 기록들을 다시 열람함으로써 추억을 회상할 수 있다. 이에 우리는 실제 생활하는 특정 공간에 자신의 감정을 기록할 수 있는 가상 나무를 심고, 해당 나무에 기록을 남기면서 생각을 정리할 수 있다. 본 논문에서는 나무를 메타포로 설정하여 공간의 축을 고정시키고 시간의 흐름을 더욱 부각시킴으로서 기억이 일상 공간에 뿌리내리듯 공간의 확립성을 부여하였다.
