This paper proposes super-resolution reconstruction algorithm for image enhancement. Super-resolution reconstruction algorithms reconstruct a high-resolution image from multi-frame low-resolution images of a scene. Conventional super- resolution reconstruction algorithms are iterative back-projection(IBP), robust super-resolution(RS)method and standard Papoulis-Gerchberg(PG)method. However, traditional methods have some problems such as rotation and ringing. So, this paper proposes modified algorithm to improve the problem. Experimental results show that this proposed algorithm solve the problem. As a result, the proposed method showed an increase in the PSNR for traditional super-resolution reconstruction algorithms.

In this paper, we proposes the steps adopted to construct the neural network model for GMAW welds. Conventional, automated process generally involves sophisticated sensing and control techniques applied to various processing parameters. Welding parameters are influenced by numerous factors, such as welding current, arc voltage, torch travel speed, electrode condition and shielding gas type and flow rate etc. In traditional work, the structural mathematical models have been used to represent this relationship. Contrary to the traditional model method, neural network models are based on non-parametric modeling techniques. For the welding process modeling, the non-linearity at well as the coupled input characteristics makes it apparent that the neural network is probably the most suitable candidate for this task. Finally, a suitable proposal to improve the construction of the model has also been presented in the paper.

Grid provides integral ing system that enables to use distributed computing resource and services as adapts traditional infrastructures to overcome the distributed computing environments. But, computing today is moving away from a restriction of the desktop, becoming diffused into our surrounding and onto our personal digital devices. In such mobile computing environments, users expects to access resource and services at any time from anywhere in such Mobile-Grid computing. This expectation results security issues, since the computing environments is expanded. This paper describes the security challenges in Mobile-Grid computing, explaining why traditional security mechanism fail to meet the demands of these environments. This paper describes policy driven security mechanism enabled entity to use service and data in trust Mobile-Grid environments and a set of security service module that need to be realized in the Mobile-Grid security architecture presents a set of use pattern that show hew these modules can be used for billing service in a secure Mobile-Grid environments.

An understanding of performance of database driven network applications is critical in combating slow performance of e-commerce web sites, besides efficient web page design, and high quality and well-maintained web server equipment. This paper describes a method of measuring performance from the user viewpoint, which can help enormously in making realistic assessment of true performance of database driven applications. The performance measurements were taken at user locations by using several specially designed JavaScript functions along with ASP scripts. A performance study is presented in this paper, comparing performance of data access using stored procedures with the traditional way of querying a database. It is generally believed that stored procedures have performance benefits as they are pre-compiled. However, our study shows that the data access approach using stored procedures provides significant benefits(by about 30%) over the traditional approach for querying a commercial MySQL database, only when retrieving a substantial amount of data(at least 10,000 rows of data).

Geometric shape morphing is an interesting geometric operation that interpolates two geometric shapes to generate in-betweens. It is well known that Minkowski operations can be used to test and build collision-free motion paths and to modify shapes in digital image processing. In this paper, we present a new geometric modeling technique to control the morphing on geometric shapes based on Minkowski sum. The basic idea develops from the linear interpolation on two geometric shapes where the traditional algebraic sum is replaced by Minkowski sum. We extend this scheme into a Bezier-like control structure with multiple control shapes, which enables the interactive control over the intermediate shapes during the morphing sequence as in the traditional CAGD curve/surface editing. Moreover, we apply the theory of blossoming to our control structure, whereby our control structure becomes even more flexible and general. In this paper, we present mathematical models of control structure, their properties, and computational issues with examples.

This study investigated news comprehension via the social media by comparing the reading of a news story on the news paper. A news story on the social media was suggested to present information in a conversational form, which differs from a traditional reporting style. To compare the different forms of news information presentation, two conditions were created: in a control condition, a news story was written in a traditional reporting form. In the experimental condition, the same news story was constructed in a conversational form. Participants were assigned randomly in one of two conditions. They read the news story and afterwards, they were asked to recall firstly, the core idea of the news story, secondly the whole news story, and finally to answer to the 10 questions that assessed how well they learned from the news story. Participants' responses were content-analyzed and produced six variables, the extent to recall the core idea, the extent to recall the whole story, the extent to recall wrong information, the extent to recall additional information, the extent to recall causally related contents in general, and finally the extent to recall causally related contents in story-specific. Analyses on the six variables revealed that the group in the news paper condition recalled more core idea, the whole story, and additional information than the group in the social media. But the news paper condition recalled less of wrong information than the group in the social media condition. Additionally, the news paper condition learned more than the group in the social media. Regarding the recall of causally related contents, the general causal relationships were recalled more in the group in the social media condition but the story specific causal relationships were recalled more in the group in the news paper condition. The findings seemingly indicated that a traditional news reporting contributes to news story comprehension more than the conversational form. Authors however added discussions and advised that the findings needed to be read under caution.

Objectives : The purpose of this paper is to describe how Wu Kun(吳昆) understood Huangdineijing 『黃帝內經』 and implemented his understanding when writting Yifangkao 『醫方考』. Methods : From Yifangkao 『醫方考』, we collected all paragraphs including "經曰", "內經曰" while excluding the ones with "論曰" to filter out Sanghanlun 『傷寒論』's perspective. The contents of Huangdineijing·Suwen 『黃帝內經·素問』 and Huangdineijing·Lingshu 『黃帝內經·靈樞』, cited in Wu Kun's Yifangkao 『醫方考』 were extracted, identified from which part it comes and sorted into headings under RyuPyeon Huangjenaegyung 『類編黃帝內經』. Results : The most cited traditional chinese medical classic in Yifangkao 『醫方考』 was Huangdineijing·Suwen 『黃帝內經·素問』 Yinyangyingxiangdalun 「陰陽應象大論篇」 which was cited 41 times. Zhizhenyaodalun 「至眞要大論篇」 had a total of 39 citations followed by Shengqitongtianlun 「生氣通天論篇」 and Liuyuanzhengjidalun 「六元正紀大論篇」 which were cited 13 times and 11 times each. In addition, it was confirmed that other 28 chapters from Huangdineijing·Suwen 『黃帝內經· 素問』, 3 chapters from Huangdineijing·Lingshu 『黃帝內經·靈樞』, 3 chapters from Nanjing 『難經』 and one chapter from Zhenjiujiayijing 『鍼灸甲乙經』 were also cited. Also the analysis of the classification of the Huangdineijing·Suwen 『黃帝內 經·素問』 showed that 57 citations were classified as 'treatment', 41 citations were classified as 'Yin and Yang and Five phases', 39 citations were calssified as 'Cause and Mechanism of Disease'. Conclusion : 1. Yifangkao 『醫方考』 have explained prescriptions by implementing principles from 5 kinds of traditional chinese medical classic including Huangdineijing·Suwen 『黃帝內經·素問』, Huangdineijing·Lingshu 『黃帝內經·靈樞』 etc. 2. According to table 3, Yifangkao 『醫方考』 have cited Huangdineijing·Suwen 『』 to explain how each compounds were used and how the Korean medical principle of Yin and Yang was applied in the prescriptions. 3. It can be suggested in formula study there is utility to understand principles of traditional chinese medical classic to comprehend prescriptions.

Introduction : Interests in personalized medicine or tailored medicine is growing in recent years, but traditional medicine with properties of tailored medicine have already been developing from many parts of the world. In this review paper, we tried to investigate the current research status and characteristics of traditional constitutional medicine by a comparative study. Methods and Material : We compared Sasang medicine from Korea, Ikkando medicine from Japan, Chinese constitutional medicine, Ayurveda from India. We investigated the current research status by searching academic DBs such as Medline, Riss4u, Kiss, CNKI, CINII. Then we examined characteristics of each medicine from various aspects of physiology-pathology-diagnosis-treatment-prevention. Results : We found out that each constitutional medicine is being studied the most in their native land. In addition, after analysing characteristics of these constitutional medicine, we learned that Sasang medicine and Ayurveda were putting emphasis on psychological factors in physiology-pathology-diagnosis-treatment-prevention, while Chinese constitutional medicine and Ikkando medicine were focusing on pathological factors. Discussion : We studied theories of constitutional medicine in various traditional medicine, and verified that Sasang medicine shares similarities and differences with these medicine. We suggest that deeper understandings of other constitutional medicine and attempts at clinical application can lead to advance of Sasang medicine.
