The contemporary age is a period of PR for the self. Regardless of how good the quality of goods or services offered is, if it is not made known to the buyers, a sell is impossible. As a result, the contemporary man is flooded with advertisements and is living in a time of over-saturated information. This is not much different in the medical services sector, as it too is experiencing an overflow of information due to the expansion of advertisement approaches to include not only the previous positive-method, but also the negative-method. In tandem, recent advancements in electronics and information technology has made possible a rapid increase in then number of internet advertisements. However, outmoded medical law, which was created to regulate newspapers and billboards, is still being applied to regulate today's modem medical advertisements. At the same time, collateral ordinances such as "corrective statutes for signs and advertisements" are not sufficient in providing the necessary regulatory countermeasures. In the midst of all this, as IPTV is scheduled to be broadcast nationwide starting next year, and with the market for search advertisements and internet advertisements annually growing at a rapid pace, it has become evermore urgent to come up with an adequate regulatory measure. Consequently, it is necessary to look into the possibility of restricting the medium and content of internet medical advertisements as well as realistic schemes for its realization. In particular, regulatory measures that take into consideration the special characteristics of internet advertisements should be found, and the necessity of an prior deliberation procedure and the likelihood of introducing a certification system should be examined.

IMT-2000 appeared in order to satisfy the desires of the uses who wish to supply through wireless most of the services being provided through wire, such as Internet services and multimedia high-speed data information. However, during global roaming, the signal data and the user data get transmitted through the networks of other users. Also, it is judged that with the provision of high speed data communication the amount of data communication necessary for confidentiality protection will increase. It is planned that the recent IMT-2000 Project will begin its commercial service in 2002. From this viewpoint, wireless contents, due to their special characteristics, are greatly exposed to illegal actions by third persons. As a result, it can be said that security and certification issues in the mobile telecommunication environment are indispensable matters. For this purpose, it is intended that in this thesis through an analysis of the existent IMT-2000 certification method, a more safe and efficient authentication method is presented and, at the same time, a security protocol necessary in the provision of wireless contents is designed.

As computers and networks become popular, distributing information on the Internet is common in our daily life. Also, the explosion of the Internet, of wireless digital communication and data exchange on Internet has rapidly changed the way we connect with other people. But secure mail is gaining popularity abroad and domestically because of their nature of providing security. That is. It has been used a variety of fields such as general mail and e-mail for advertisement. But, As the data transmitted on network can be easily opened or forged with simple operations. Most of existing e-mail system don't have any security on the transmitted information. Thus, security mail system need to provide security including message encryption, content integrity, message origin authentication, and non-repudiation. In this paper, we design and implement secure mail system with secure key agreement algorithm, non-repudiation service, and encryption capability to provide services for certification of delivery and certification of content as well as the basic security services.

Methods: The subjects were staff in charge of alcohol prevention services in four organizations. A questionnaire was modified pursuant to the IC & RC (International Certification & Reciprocity Consortium) Certified Prevention Specialist role delineation. The questionnaire consisted of five domains with 27 items. Data were collected via the self-administered questionnaire from October to November of 2009. 400 questionnaires were mailed and 144(36.0%) were returned. The collected data were analyzed using the Borich's needs assessment model and with SPSS/WIN 15.0. Results: Overall mean scores for the importance levels of competency ratings were 3.79, while the performance levels of the competency were 2.13 and Borich's need results were 6.32. Public Health and Mental Health Center showed the highest degree of educational needs in terms of education & program development (p=.022). Conclusion: The perceived importance levels pertaining to staff competency for alcohol prevention services in the workplace were higher than those of the current performance levels. Staff working for alcohol prevention services in the workplace showed a different level of educational need as regards these competency levels according to service providers. To promote the effectiveness of alcohol prevention services in the workplace, the development of an educational program to meet the needs of the service providers is necessary.

Purpose - The number of consumers adopting a lifestyle of health and sustainability has recently increased with the rise of trends in healthy living. The size of the organic agricultural product market has also increased given that these consumers prefer consuming environmentally friendly products that promote family health. However, awareness of organic agricultural products remains insufficient because of the characteristics of the Korean organic agriculture system, which only focuses on food safety inspection. The object of this research is to suggest a policy approach to increase understanding and to expand the purchasing of organic agricultural products by analyzing the influence of customer recognition of such products on their willingness to repurchase. Research design, data, and methodology - This study used binomial logistic regression analysis with the aim of explaining the effects of consumers' socio-demographic characteristics, their awareness of the equivalence arrangement for organic food and of the abolishment of low-pesticide agricultural product certification, and their viewing of negative broadcasts about organic agricultural products on their repurchase intention of such products. A questionnaire survey was conducted with 655 respondents who were in their 20s, lived either in Seoul or in its metropolitan area, and had purchased organic agricultural products. Result - From the results of the analysis, the majority of the respondents recognized organic agricultural products, but they found their prices to be expensive. The majority of the respondents were also aware of the certification system and the reliability of organic agricultural products. However, the results indicate that efforts need to be made to recover consumer trust as many respondents stated that their trust levels in these products were low. In general, those purchasing organic agricultural products were satisfied, but those answering "very satisfied" were not in the majority. Binomial logistic regression analysis results revealed that repurchase intention decreased as consumers viewed a greater number of negative broadcasts about these products. On the other hand, repurchase intention increased as they became more aware of the abolishment of low-pesticide certification. Repurchase intention also increased as income increased, as the number of family members decreased, and when a consumer was a member of a consumer organization. In addition, the older the consumers were who watched the TV programs, the smaller the number of family members that were aware of the abolishment of low-pesticide agricultural product certification and, the higher the income of the consumers aware of organic equivalence arrangement, the greater their repurchase intention. Conclusion - External stimuli, such as negative TV programs on organic agricultural products and the abolishment of the low-pesticide agricultural product certification, relevant social issues and systems, influence consumer repurchase intention. To that end, positive environmental and ecological broadcasting about organic agricultural products would contribute to an increase in purchasing. Additionally, this could be used for promotion and marketing plans as the results indicate that trust in organic agricultural products would cause a positive repurchasing effect.

The application contents, process, and its limitations are discussed for the setting of Korean legal guides & criteria for water cycle and ecological condition in development project of land use by thorough comparison and examination of prerequisites and credits of water cycle and soil+vegetation by USA's SITES (Sustainable Sites Initiative). In the case of SITES, due to the implementation procedure operated as a non-governmental independent assessment system by Green Business Certification, Inc, the natural condition of water cycle and soil-vegetation items-the key element of ecosystem services can be quantitatively assessed, well along with its legal and institutional guidelines and regulations. On the other hand, in the case of Korea, as a part of the national certification procedure for green building, the ecological area ratio system still have very limited role as an only amenity resource in the creation of artificial green spaces and insufficiency of management system for rain water. In conclusion, it was understood as an urgent situation in necessary for prompt establishment of site's sustainability certification system at the national level, based on management of water circulation and natural soil & vegetation in developed area with consideration of various land uses and types of development projects.

The purpose of this study was to investigate music therapists' awareness of the music therapy national certification (MTNC). Online questionnaires were distributed to music therapists who voluntarily agreed to participate in this research and 143 completed surveys were collected for analysis. The questionnaire consisted of 37 questions (background information, awareness of the necessity for MTNC, expected effects of national certification, and qualification management). According to the collected data, music therapists reported that they were highly aware of the necessity for MTNC. The participants believed that excessive issueing of private licenses might deteriorate the quality of music therapy services and job opportunities. As alternatives to address private license-related issues, participants agreed with the establishment of national certification system. Given that participants did not have enough knowledge of MTNC and the MTNC may have both pros and cons, the results should be generalized with caution. Still, this study could provide basic information for further discussion on the establishment of MTNC.

A robot-friendly building certification system was established in 2022 to accommodate the growing number of service robots introduced into buildings. However, this system primarily targeted office buildings, with limitations in applying other functional architectures. To address this problem, we developed a certification model of a robot-friendly environment to extend the existing system to apartment complexes. Using focus group interviews and the analytic hierarchy process, we established 28 evaluating items categorized as (a) architecture and facility design, (b) networks and systems, (c) building operations management, and (d) support for robot activity and other services. These indicators were weighted based on their relative importance within and between categories, resulting in scores ranging from 1 to 18 points and a total of 176 points. According to evaluations with the 28 items, each apartment complex could be graded as "best," "excellent," or "general" based on its total achieved scores. This study is significant, as we present the world's first certification model of a robot-friendly environment for apartment complexes that considers human-robot interactions
