Information is playing a key role in sufficing the needs of individual members of the society in today's rapidly changing environment. Especially, the cases of illegal gathering of privacy information will increase and the leakage of privacy information will grow as the individual activities in the ubiquitous computing environment. In this paper, we suggested the privacy framework in order to make design and implementation of secure and effective privacy management system. Ant we also introduced the methodology which is represent to 5 specific stages in order to suggest to the privacy system development guideline from the standpoints of the privacy system operator or developer. Especially, we tried to determine whether the suggested methodology can be effectively used in the real computing environment or not by making necessary investments in management (privacy policy) and technical (system architecture) sides. We believe that the privacy framework and methodology introduced in this research can be utilized to suggest new approach for showing direction from the privacy protection perspective, which is becoming more important in ubiquitous environments, and practical application rather than providing conceptual explanation from the views of engineer or developer.

This study is a study on System On Chip (SOC) that implements virtual engine sound in electric vehicles without engines, and realizes vivid engine sound by combining Adaptive Difference PCM (ADPCM) method and frequency modulation method for satisfaction of driver's needs and safety of pedestrians. In addition, by proposing an electronic sound synthesis algorithm applying Musical Instrument Didital Interface (MIDI), an engine sound synthesis method and a constitutive model of an engine sound generation system are presented. In order to satisfy both drivers and pedestrians, this study uses Controller Area Network (CAN) communication to receive information such as Revolution Per Minute (RPM), vehicle speed, accelerator pedal depressed amount, torque, etc., transmitted according to the driver's driving habits, and then modulates the frequency according to the appropriate preset parameters We implemented an interaction algorithm that accurately reflects the intention of the system and driver by using interpolation for the system, ADPCM algorithm for reducing the amount of information, and MIDI format information for making engine sound easier.

The number of internet users and the scale of electronic on-line trading are on the increase due to the development of information technology and the internet. The aim of this study was to monitor the accuracy of country-of-origin labels and the indicated contents of meat available by electronic on-line trading by using a structural interview sheet for 100 on-line meat product markets. The result of this investigation showed a 100% level of accuracy for business name and telephone number whereas the company address, meat manufacturer and supplier, and business registration were less reliable. We also investigated the accuracy of site policy, e-mail address, and fax number. The results showed that the accuracy of fax numbers was the lowest. The product name and the kind of meat actually in the product showed a 100% level of conformity, while the price (96.3%), place of origin (93.6%), capacity (90.4%), meat parts (80.9%) and contents of the product (73.4%) showed a relatively low level of conformity. Serious safety issues were exposed by the disturbingly low 20.2% accuracy of indicated expiration dates and 5.3% accuracy of indicated manufacturing dates. To ensure food safety, it is essential to improve consumer understanding and trust regarding food safety through continuous public relations. More education and information are needed to raise consumer awareness of the facts versus myths regarding food safety.

Private detectives and investigators offer many services, including executive, corporate, and celebrity protection; pre-employment verification; and individual background profiles. They also investigate computer crimes, personal injury cases, insurance claims and fraud, child custody and protection cases, missing persons cases, and premarital screening. This paper focuses on a private detective or investigator system in most developed U.S.A, but it is not easy to describe that system. Licensing requirements vary in U.S.A. Some States have few requirements, and many other States have stringent regulations. A growing number of States are enacting mandatory training programs for private detectives and investigators. Employment and need of private detectives and investigators is expected to grow faster than the average for all occupations. Thus, it is reasonable that korean government should permit private investigation service find the way to minimize the side effects of private investigation service instead of banning the service totally.

In recent years Mag-Geol-Li is becoming popular again and the consumption layer of Mag-Geol-Li is definitely younger. Nowadays, Mag-Geol-Li is the main traditional alcohol and without consideration of ages and genders whoever can enjoy Mag-Geol-Li. Producers should ensure fair price of goods and improve production facilities to maximize products to meet the needs of consumers who will buy. In the studies I discuss about the ways to improve the distribution of Mag-Geol-Li, the theories about Mag-Geol-Li, Social backgrounds and effects of Mag-Geol-Li why it is becoming popular and improvement of the distribution structure of Mag-Geol-Li and impact of big Mag-Geol-Li company in Mag-Geol-Li industry. Lately, people can enjoy Mag-Geol-Li without burden because of low alcohol. It is gaining a good response by consumers because Mag-Geol-Li contains lactobacillus, yeasts and dietary fiber, also it is well balanced with nutritional aspects. There are not only huge factory to produce Mag-Geol-Li but also most are still cottage industry. Therefore, quality management does not work well because the majority of Mag-Geol-Li is small businesses. In spite of there are a lot of ways to improve the distribution structure and problems of Mag-Geol-Li, but none provide any improvement that make consumer awareness about the main cause of the problem is inaccurate. The ultimate goal of improving the distribution structure of Mag-Geol-Li is activating the market, the improvement of production facilities and safe for consumers with affordable price and good quality product. As mentioned above, to improve and change the logistics systems and hygiene, government support is required and Mag-Geol-Li companies should be recognized the distribution system as a major problem.

As the quality of life has improved, the desire for the safety and quality of the foods and drugs has been gradually increasing. For safety and quality management in foods, drugs, health management, agriculture, environmental conservation, and the industrial fields, the demand for quickly and accurately measuring various chemicals has been increasing. As well, the desire for self-diagnosis of one's own health state and self-examining the safety of environment has been gradually increasing. Optical Isomers can have very different physiological effects on human beings. One isomer can exhibit desirable pharmacological, pharmacodynamic, pharmacokinetic and physiological properties, while the other isomer can exhibit undesirable and toxic properties toward living organisms, especially human beings. And they can exhibit different activities in chemical and biotechnological processes. Although the majority of commercially available drugs are now both synthetic and chiral materials, a most chiral drugs are still marketed as racemic drugs. Thus, to avoid possible undesirable side effects from chiral drugs, more effective methods for separating and recognizing chiral compounds are urgently needed. In this report, we investigated the overall developing trends of the chiral drug separation and analysis technology by using molecular recognition.
