  • The personal information extrusion accident(hacking, improper maintenance) by the internet has been increased rapidly during the last ten-year period. The personal information includes Korean resident registration number, name, cellphone number, home telephone number, E-mail address, home address, etc. Korean resident registration number is unchangeable from the cradle to the grave. Illegally accessed personal information can be wrongfully resoled or used at phishing scam. In this paper, we propose a alternative means of Korean resident registration number using the authorized certificate. The authorized certificate is in use safely in Internet. The authorized certificate(included Chinese name) is in used in offline service, the authorized certificate(included English name) is used in online(for government service) and the authorized certificate(not included name) is used in online(for private service). The authorized certificates are possible for discard, republication. The method can reduce the possibility of the personal information extrusion.

  • The NGO program of "intestinal parasite Control among primary Schoolchildren of Lao PDR", supported by KOICA and implemented by KAHP, has started in 1999 and will be executed until 2004. Under cooperation of the LAo Ministry of Health, WHO, Korean Embassy and KOCIA, for the last 4 years, KHIP has conducted parasitological survey throughout the country, supply of medical equipment and anti-helminthics and treatment of positive people. The results of the survey is as below : A total of 29,846 stool specimens were collected from primary schoolchildren from May 2000 to June 2002 and examined once with the cellphone thick smear. By species, the rate for Ascaris lumbricoides was 34.9%, hookworm 19.1%, Trichuris trihiura 25.8%, Opisthorchis iverrini 10.9%, Taenia spp. 0.6% and Hymenolepis spp. 0.1%. The northern mountainous regions showed a higher prevalence of soil-transmitted helminths. The regions along the Mekong River such as Khammuane, Saravane or Svannakhet Province showed a higher prevalence of fish-borne parasites.

  • A method to detect Trojan horses in messaging and Bluetooth in mobile phones by means of monitoring the events produced by the infections is presented in this paper. The structure of the detection approach is split into two modules: the first is the Monitoring module which controls connection requests and sent/received files, and the second is the Graphical User module which shows messages and, under suspicious situations, reports the user about a possible malware. Prototypes have been implemented on different mobile operating systems to test its feasibility on real cellphone malware. Experimental results are shown to be promising since this approach effectively detects various known malware.

  • A cell phone is a necessity for the modern society. The function of mobile phone enables us to exchange various information beyond the time and space. In addition it has lots of function such as shooting of moving picture. This study is to research the accuracy and rapidity of the information by means of SMS, and to propose a new system of transmission in order to create a profit for the life economy. Through the function, which is suggested in this paper, we can store the phone number to the sending category of the other party's phone by combining character or number. We can expect the most accuracy and swiftness of the cellphone information via of this proposed research.

  • In this paper, we have implemented the device management system to upgrade T-PAK software in mobile phone. The hybrid scheduling method and selective upgrade method are proposed. Hybrid scheduling method is based on distribution of delivery data in accordance with network traffic load and service priority from device management server to mobile phone. Selective upgrade method manages DSL classified by T-PAK software version to be upgrade using version management established in OMA DM SCOMO. Key mechanism of selective upgrade method is to only deliver DSL to be replaced to the mobile phone. We made an experiment on two methods using MS-700T terminals. The experimental result shows that the proposed method is faster than normal from delivery time standpoint.

  • In this paper, we develope a defect inspection method for each buttons of keypad of cellular phones before they are assembled. The proposed algorithm consists of the similar color checking and its classification, font error detection, and scratch detection based on the segmentation of keypad area and font, translation and rotation processing sequentially. Especially, the proposed segmentation method approximate the pad region as B-spline function to deal with illumination change due to the shape of key button with the slant and curved surface followed by simple thresholding. And also, the rotational information is obtained by using eigen value and eigen vector very fast and effectively. The experimental results show that the performance of the proposed algorithm is good when it is applied to in-line process.

  • Mobile communication industry is attracting a lot of attention all over the world and is expected to continue developing endlessly with the current rapid development of IT industry. Nowadays, mobile communication companies of vietnam are competing about service quality in order to retain existing customers and improve customer satisfaction and customer loyalty. This study attempts to research about the effect of mobile communication service quality on customer satisfaction and affecting relationship between customers satisfaction and customer loyalty. In this research empirically examine how mobile communication service quality influence customer loyalty in Vietnam. To do this, after considering characteristics of mobile communication service quality, quality measurement instrument was designed including call quality, call charge, cellphone, added service quality, corporate image, employee's attitude, and behavior. The study finds that all factors of call quality, added servces quality, corporate image, employee's attitude and behavior have positive effect on customer satisfaction except call charge and customers satisfaction also effects customers loyalty positively. From these results, Vietnam domestic mobile communication companies and foreign companies can grasp the general information about Vietnam mobile communication industry, and then, establish customers satisfaction strategies more effectively.

  • Before Smartphone releases, playing music form previous cellphone is very limited, so we need mp3 player instead. However, when Smartphone releases, a function of playing multimedia became one of the important things in Samrtphone including all functions of mp3 player. Even though it is easier to use since you can play music and multimedia in one device, it still has problem issues on the sound quality. This thesis will discuss about functions of EQ from Smartphone music players. After that, we will to achieve high fidelity sound through balance adjustment of Right Mark Audio Analyzer program.

  • Tolerance analysis is one of the most important processes to improve the image quality of products. High resolution camera module for mobile phones needs precision assembly technology since the module becomes smaller and thinner. This paper will focus on the unit tolerance and the assembly tolerance which can affect the performance of the module. Lens shading and relative illumination were used to evaluate the optical axis scatter for each component on camera and estimate the assembly yield rate based on the evaluation result. A program was developed to analyze the impact on optical axis by each module, then to optimize the dimensions and tolerance for reducing the scatter of optical axis assembly. Through the simulation, though a rate of relative illumination was declined in where optical axis is displaced $100{\mu}m$ from sensor center, MTF performance is not influenced by increasing in optical axis displacement. It was seen that assembly yield was improved in result of simulation after correcting optical axis tolerance.
