Objectives: The development of internet programs for smoking cessation was motivated to quit smoking in the large group of smokers. This personalized program consisted of tailored message to consider the smokers characteristics, and contain the informations on the outcomes of smoking cessation and the skills to be used in the quit attempts. The purpose of this study was to develop the internet management program and information push-delivery system for smoking cessation to encourage the personal intention to quit smoking. Methods: We conducted in 3 steps as developing push service to encourage intention of smoking cessation, analyzing problems of smoking cessation program through the pilot test and suggesting improvements by implication stages. Results: This program is delivered for 30 days. if the participants do not fail to quit smoking. The contents consisted of 13 stages which were divided on starting period. practical period, maintenance period and success period. And push service afforded the tailored message to participants using their e-mail. According to the evaluation of pilot test, the problems of internet information push-delivery service for smoking cessation were the over-tasks per visiting time, recording style of participants, difficulty of terms and sentences, lack of visual effects, absence of follow-up module and unsuitable link with main homepage. Improvements were divided on 3 stages by implication period. The first stage included the immediate improvements as improving link with homepage, modifying menu of smoking information and upload file of notice part. The second stage included the short term improvements as alleviating condition of withdrawal, coordinating start stage of retrial, modifying errors of information push-delivery service and addition of educational materials. The third stage included the long term improvements as development of follow-up module, cost-effectiveness evaluation, reducing contents quantity, introduction of checking style, compensation of graphics effect and review for SMS utilization. Conclusions: This program contribute to improving smoking cessation rate. Therefore this program should be tested in a community to evaluate the effectiveness.

모바일 폰의 메뉴 구조는 하이퍼텍스트 형태로 정보를 제공하며 링크의 연결로 페이지 정보를 전달하거나 하부 카테고리로 연결하는 역할을 한다. 모바일 폰 사용자는 메뉴 조작을 통해 기능을 실행하며, 이 과정에서 선형구조, 계층형 구조, 대화형 구조, 데이터베이스 구조, 혼합구조와 같은 다양한 형태를 경험하게 된다. 사용자는 모바일 폰의 다양한 기능을 사용하면서 추상적 개념의 공간 인지를 구체적인 공간으로 이해하려 한다. 즉 UI, GUI에서 제시하고 있는 Label이나 방향표시를 따라 상하좌우라는 공간적 개념으로 은유하여 이해하는 것이다. 하드키 단말의 경우는 상하좌우키를 이용하여 공간을 이해했다면 최근에는 터치 및 제스처 동작 인식이 가능한 폰이 등장하면서 좌우 flick, 상하 flick 등과 같은 구체적인 행동으로 디바이스 화면에서 공간이 이동하는 것으로 이해하고 있다. 본 논문에서 사용자의 공간 은유를 이해하기 위해 상위 depth로 이동하는 [이전] 키의 기능을 중심으로 살펴보고자 한다. 첫째, 기능을 수행하기 위해 순차적으로 진행하는 방법보다는 [취소]를 이용하여 depth를 이동하는 것이 사용자의 모바일 폰의 공간 은유 파악에 더욱 도움을 줄 수 있을 것이라고 예상되기 때문이다. 둘째, [이전], [취소]라는 Label이 가지고 있는 모호성 때문이다. 모바일 폰의 다양한 기능 중에서 [이전]는 전체 사용에 있어 아주 작은 요소에 불과하지만 사용자는 정해진 순서의 process에 따라 기능을 수행할 때와는 다르게 역 방향 Process를 사용하면서 모바일 폰의 구조를 이해하고 모바일 공간을 인지하는 중요한 요소로 사용될 수 있을 것이라고 예상된다. 본 논문에서는 이전으로 돌아가는 [이전]의 기능을 통해 사용자가 메뉴의 층위 구조 및 공간 인지에 영향을 미칠 수 있을 것이다라는 가설을 설정하여 이를 실험을 통해 증명하고자 한다. 실험을 위해 모바일 폰을 자주 사용하고 있는 20~30대 남녀 10명의 피험자에게 전화번호부, 앨범, 문자메시지의 목록화면과 상세보기 화면을 제시한 후 마지막 상세보기 화면에서 실험에서 제시하는 제시어를 보고 어느 화면으로 이동하게 될 것인지를 예상하는 질문을 하였으며, 그러한 이유에 대해서는 인터뷰를 통해 확인하였다. 이 실험을 통해 사용자의 모바일 폰 공간인지는 동일한 레벨의 단계 즉 상세보기의 경우는 수평의 관계라고 보고 있으며, 목록화면과 상세화면의 관계는 상하의 관계라고 이해하고 있다. 이러한 이유를 인터뷰를 통해 질문하였을 때, 상세화면에서 좌우 방향표시가 존재하기 때문이라는 응답이 높았으며, 상세보기 화면이 좌우라고 인식하면 목록화면은 상하의 관계로 이해하고 있다고 응답하였다. 즉 하나의 정해진 공간인지를 통해 다른 공간을 유추하여 생각하고 있다고 볼 수 있다. 또한 결과적으로 실제 단말에서 [이전] 기능을 상위 depth로 이동하도록 설계하였다면 [한단계위]라는 Label 또는 e번과 같은 상위의 개념을 포함한 아이콘을 사용한다면 혼란을 줄일 수 있는 방법으로 활용될 수 있을 것으로 예상된다. 현재 논문에서는 [이전]라는 기능으로만 사용자의 공간 개념을 예측할 수 있었지만, 터치스크린의 등장과 함께 플릭과 같은 다양한 제스처에 의한 인터렉션이 가능한 현 시점에서 추상적인 공간은 방향성을 가진 제스처에 의해 구체적인 물리적 공간으로 인식하는 경향이 더욱 뚜렷이 나타나고 있다. 이러한 시점에서 사용자의 공간인지에 도움을 줄 수 있는 Label과 방향성 표시는 더욱 절실히 요구되고 있는 시점이며, 이후 모바일 환경에서 사용자의 공간인지에 대한 구체적인 연구가 필요하리라고 예상된다.

This paper presents the design of service model, transport channel, and service signaling for the Terrestrial DMB Automatic Emergency Alert Service (AEAS) Standard. The paper begins with the analysis of technical backgrounds related to the design topics. Next, the raper presents the design of service model for the AEAS. Since, unlike the regular T-DMB services, the AEAS is event-driven and common to all services, some problems have been identified to design a service model conforming to the T-DMB standard. So, the paper proposes a new concept, called the common service, and the AEAS is modeled using the common service. Next, in order to decide the transport channel for the alert information, the paper proposes to divide the alert information into the message which contains code/text-based essential information, and the supplemental multimedia information. Then, the paper tries to find the most efficient transport channels. Emergency Warning Service (EWS) which uses FIG 5/2 is selected for the delivery of the message. The paper proposes no constraints on delivery of supplemental information except that it shall use the MSC. Finally, it proposes the service signaling for the common service and transport channel. Due to the problems of conventional signaling using the MCI, it proposes a new signaling method. The paper will contribute as a guideline to the development for emergency alert service standards fur other broadcasting media.

According to recent studies, the location of visual information has a significant impact on consumers' interpretation and judgment in various contexts. In particular, vertical positioning is relevant to the perception of weight: consumers tend to interpret that products are heavier when information is placed at the bottom of a page or section rather than the top. This is due to the common perception that heavy things would sink to the bottom and light things would float up. Consistent with this research stream, the current study investigates how the vertical location of freebie information influences promotion evaluation. We hypothesize that consumers assume that the complimentary product is heavier when the information about it is displayed at the bottom compared to when the information is displayed at the top. Two experiments were conducted. In experiment 1, we show how the location of "get one free" information impacts the evaluation of the sales promotion in a "Buy two and get one free" context. When the complimentary information was displayed below rather than above the main product information, consumers evaluated the sales promotion more favorably. Experiment 2 tests the generalizability of the vertical location effect by using a different type of information and product: a visual picture of vitamin tablets rather than the numeric information as in Experiment 1. The dependent variable was also extended to the perceived amount of the promoted product. We suggest the boundary condition that the proposed effect is moderated by the presence or absence of an explicit message about the amount. Without an explicit message about the amount of the product, the results were similar to those of experiment 1 in that consumers perceived that the product offered a greater amount when the complimentary information was displayed at the bottom rather than at the top. However, the location effect disappeared with an explicit message about the amount. This confirms the moderating effect that presenting an explicit message about the amount is a crucial boundary condition for location effect in a value added promotion. Marketers can use this knowledge to formulate strategies in a variety of sales promotion conditions.

전자우편이나 문자 메세지를 이용할 때 겪는 불편함 중 하나는 상대방이나 기계에 정서 정보를 전달하기 어렵다는 점이다. 정서 정보를 메시지에 싣기 위해서는 컴퓨터나 디지털 기기가 정서를 인식하거나 사용자가 정서를 입력해야 한다. 기존의 정서 인식 방법은 생리적, 신체적 측정치를 이용하는 것인데, 이 경우 측정을 위한 별도의 장비가 필요하고 현재 자신의 정서 상태와 다른 정서를 표현할 수 없다는 단점이 있다. 특히 소형 모바일 기기를 이용할 때 다른 측정 장치를 사용하는 것은 더욱 어렵다. 이런 문제를 해결하기 위해 모바일 기기를 사용하는 환경에서 사용자가 원하는 정서를 기계에 입력하기 위해 동작을 이용하려는 연구가 진행되었다(Fargerberg, Stahl, & Hook, 2003). 본 연구에서는 Laban Movement Analysis에서 동작을 구성하는 다섯 요소 중 노력(effort)과 모양(shape) 요소를 재구성하여, 방향성 차원, 무게감 차원, 시간감 차원으로 동작을 구분하고 총 20개의 동작을 선정하였다. 또한 한덕웅과 강혜자(2000)가 수집한 834개 정서 어휘를 평정하여 동작을 통해 표현하고 전달되기 쉬운 정서 어휘 50개를 선택하였다. 최종 실험에서 참가자들은 20개의 동작에 대해 50개의 정서 어휘를 평정하고 데이터는 범주형 주성분분석을 이용하여 분석하였다. 분석 결과 Russell(1980)의 이차원 정서 구조 모형에서 각성 수준 차원은 동작의 무게감과 시간감 차원과 관련이 있는 것으로 나타났다. 강하고 빠른 동작일수록 각성 수준이 높은 정서가 나타났다. 또한 동작의 방향성 차원은 정서의 종류와 관련이 있는 것으로 드러났다. 직선 움직임은 높은 각성 수준의 부정적 정서와, 흔듦 움직임은 불안 및 초조와, 원형 움직임은 즐거운 정서와 관련이 있는 것으로 나타났다. 이는 동작을 통하여 정서 정보를 효과적으로 전달할 수 있음을 보여주었고, 동작과 정서를 연관 짓기 위해 방향성 차원과 무게감 차원 그리고 시간감 차원을 고려할 필요가 있음을 시사한다.

Motion graphic is also developing into its own genre in graphic design by establishing individual industrial fields. images and graphics but also recognize even motions and sounds as communication elements delivering a message. Nevertheless, web communication designers have yet to experimentally test the visual motion priniciples or the audio sound expressions in terms of technology. If the dance are used, they may be new communication approaches in the age of multi-media, which allows for communication of visual and audio information or images. With such conceptions in mind, this study was aimed at reviewing the structural relationship between visual motion principles of the kinetic and the sound images to combine the audio and video effects. To this end, the basic structure of dance and music were substituted into the dance to determine their relevancy, and thereupon, examine the effective sound expression methods and techniques depending on movements of the objects in the monitor. Thus, this study, by inquiring into the uniqueness of choreography in motion graphic, presents the possibility of limitless expression of designer creation and inner world, and the ultimate goal lies in assuring the artistic value of motion graphic and its position as a synthetic art.
