The objective of this study was to identify the cultural characteristics affecting advertising contents of the consumer products. Hofstedes(1991) five cultural characteristics such as individualism-collectivism, power distance, masculinity-feminity, avoidance of uncertainty, confucian dynamism were used. Ten kinds of consumer products were included and data were collected from France, Japan, Korea, and U. S. during 1999∼2000. All ads were evaluated and compared their cultural characteristics in terms of country, product involvement and usage, and magazine type. ANOVA, Duncan test, and Pearson correlation-coefficient were applied to analyze data. The results were shown as follows: First, most ads tended to be individual, less power oriented, feministic, and showed high tendency of uncertainty avoidance as well as long term confucianism for all the countries. And some cultural characteristics were different among countries. Japan, France, U. S. and Korea in order showed higher individualism and lower power distance. Also Korea and Japan showed relatively short term confucian culture while U. S. and France did ling term perspectives in the ads. Second, product involvement and usage type had a significant impact on the characteristics of individualism-collectivism and feminity-masculinity. That is, product ads of lower involvement and personal use were likely to show individualistic messages and to have more feministic appeals. Third, magazine type had an impact on some cultural characteristics. Womens magazines would have more individualistic, less power oriented, and feministic appeals of ads. In conclusion, global ads should be localized and differentiated in terms of some cultural characteristics and differ depending on product characteristics.

Purpose: Based on the results of a survey on college freshmen's smoking this study examined the application of smoking cessation programs. Methods: The opinions of 89 smokers who were college freshmen were investigated and analyzed using a survey questionnaire. Results: Among the survey respondents, the largest percentage (47.2%) replied 'little satisfied' to the question on the with campus life. Of the participants, 57.3% considered that their health state was bad because of smoking. As to motives for smoking, 'curiosity' was most frequent. Smokers had more smoking friends than nonsmoking ones. The 82% of the smokers had experience in stopping smoking. Among smoking cessation methods, the self overcoming was most frequent(50.6%). During the survey, 28 smokers applied for the cessation program and they favored e-mails for information. E-mails were sent to them once in a week for 6 weeks and short messages were sent to their cell phone in order to encourage them to read the e-mails. Conclusions: To encourage and maintain smoking cessation, it is recommended to have a personalized or small group program. More researches are needed to execute the program and evaluate results. Colleges need to have an innovative approach on smoking prevention and cessation services.

The active use of the container vessel has brought with it high speed and reduced transit time ; however, the system of delivering the goods via B/L at the destination has lagged behind technical advances, becoming a burden to today's international traders, especially consignees and/or importers. More recently the sea waybill(SWB), that is to say an ocean-type AWB, has come on the scene. In Europe and the USA the use of SWB has increased significantly, but has also left room for improvement due to its short history of use. However, Recently, more attention is paid to SWB as a means to solve the B/L Crisis is getting more and more serious. In addition, due to its non-negotiability, the sea waybill could easily be replaced by messages sent between the interested parties by Electronic Data Interchange. With the paper document, transfer of title is fulfilled by transferring the original bill of lading to the buyer of the goods. However, in an electronic environment this is difficult to replicate. A number of solutions have been investigated, including using an electronic bill of lading, by controlling changes in title to goods through irrevocable, but transferable instructions to the carrier, or by appointing an independent electronic data registry, or replacing the bill of lading with a sea waybill, which is non-negotiable. The purpose of this study is to investigate some problems which may hinder SWB from coming into wide use and to analyse how to solve problems due to introduction of electronic sea waybill.

We are living in epoch of information when Internet touches all aspects of our lives. Therefore, it provides a plenty of services each of which benefits people in different ways. Electronic Mail (E-mail), File Transfer Protocol (FTP), Voice/Video Communication, Search Engines are bright examples of Internet services. Between them Social Network Services (SNS) continuously gain its popularity over the past years. Most popular SNSs like Facebook, Weibo and Twitter generate millions of data every minute. Twitter is one of SNS which allows its users post short instant messages. They, 100 million, posted 340 million tweets per day (2012)[1]. Often big amount of data contains lots of noisy data which can be defined as uninteresting and unclassifiable data. However, researchers can take advantage of such huge information in order to analyze and extract meaningful and interesting features. The way to collect SNS data as well as tweets is handled by crawlers. Twitter crawler has recently emerged as a great tool to crawl Twitter data as well as tweets. In this project, we develop Twitter Crawler system which enables us to extract Twitter data. We implemented our system in Java language along with MySQL. We use Twitter4J which is a java library for communicating with Twitter API. The application, first, connects to Twitter API, then retrieves tweets, and stores them into database. We also develop crawling strategies to efficiently extract tweets in terms of time and amount.

이동전화 단말기의 빠른 보급률에 발맞추어 다양한 모바일 콘텐츠가 개발되고 있다. 그 중에서도 대기화면 서비스를 이용한 서비스들이 개발되었다. 본 논문에서는 휴대폰 대기 화면의 개념에 대해 알아보고 대기 화면 서비스의 환경 변화에 대해 살펴본다. 또한 대기화면에서 직접적으로 문자 메시지의 수신, 편집을 용이하게 하는 서비스를 제안한다. 기존의 문자 메시지 기능을 보완하고 규격화된 문자 메시지 송수신을 통해 미리 설정된 사용자 설정으로 휴대폰 대기 화면에서 직접 메시지를 정렬하거나 다이어리 기능을 접목하여 효과적인 정보관리가 가능하도록 한다. 논문에서 제안한 서비스는 향후 다양한 무선 단말기기에 채택되어 추가 비용 없이 사용자 정보관리에 이용될 것으로 기대된다.

Purpose: The purpose of this study was to determine the effects of 6 months lifestyle coaching program for adults with hypertension. Methods: The study utilized the one-group pretest-posttest design. The subjects were recruited from a corporation group member of a private health maintenance organization. The data of 35 subjects who completed the program out of initial 114 subjects were analyzed for this study. The program included 6 times of monthly face-to-face visits and additional short messages by cellular phone. They were given education for self-management of hypertension and coaching for lifestyle modification. Dependent variables were measured at the beginning and at the end of 6months program and compared by paired t-test. Results: There were significant reductions in systolic and diastolic BP, BMI, total cholesterol, and fasting blood sugar. Among the variables in life style, significant changes were shown in alcohol consumption (frequency and quantity) and exercise (frequency and duration). Conclusion: This study showed that 6 months lifestyle coaching program has potential for positive outcomes on BP control and modifying lifestyle for adults with hypertension. However, additional study is needed to find sustainability of lifestyle and the long-term effect of the program with larger sample.

무선 전자 장치 상에서 전자 정부의 행정 처리는 안전하지 않으므로 메시지들이 공격에 취약하다. 따라서 무선인터넷을 지원하는 장치는 유선 네트워크와 동일한 수준의 보안과 프라이버시가 보장되어야 한다. 유선 환경에서 사용되는 전자 정부의 국가 공개키 기반 구조(NPKI)는 컴퓨팅 성능, 메모리 용량 및 제한된 배터리 전력의 한계로 인해 모바일 전자 정부를 위한 무선 환경에 적합하지 않다. 이를 위해서는 유선 NPKI와 동일한 보안 수준을 제공하는 개발도상국을 위한 모바일 국가 공개키 기반구조(mPKI)의 개발이 필요하다. 무선 환경에서의 mNPKI 요구사항은 짧은 시간 한계를 갖는 인증서를 기반으로 한다. 분석 결과 mNPKI는 무선 인터넷에 적합하고 유선 NPKI와 동일한 보안과 프라이버시를 제공함을 확인하였다.

고속의 군용 항공기는 인명피해 최소화를 위해 생존 장비들과 경고 시스템으로 적의 위협 또는 내부 구성품 불량을 조종사가 파악하고 해결할 수 있어야 한다. 경고 전달은 디스플레이에 심볼 전시를 통한 시각적 방법과 통신 장비의 소리를 통한 청각적 방법으로 구분되는데, 청각적 방법이 반응 시간이 짧고 단순한 메시지 청취를 통해 조종사 혼란을 유발하지 않는다는 점에서 우월하다. 이에 본 논문은 군용 항공기용 음성/톤 경고 시스템의 효과적인 설계방법을 생명주기 관점에서 제시하고 평가하였다. 안전에 민감한 군용 항공기이므로 각 경고에 우선순위와 Inhibitible, Interruptible, Deactivatable의 세 가지 속성들을 적용하여 중대성과 긴급성을 반영했다. 그 결과 음성경고 재생까지 40ms가 소요되었으며, V모델 기반 개발 및 테스트를 통해 요구도를 모두 충족했고 제품 신뢰성이 향상됨을 확인하였다.
