  • Digital Convergence means integration between industry, technology, and contents, and in marketing, it usually comes with creation of new types of product and service under the base of digital technology as digitalization progress in electro-communication industries including telecommunication, home appliance, and computer industries. One can see digital convergence not only in instruments such as PC, AV appliances, cellular phone, but also in contents, network, service that are required in production, modification, distribution, re-production of information. Convergence in contents started around 1990. Convergence in network and service begins as broadcasting and telecommunication integrates and DMB(digital multimedia broadcasting), born in May, 2005 is the symbolic icon in this trend. There are some positive and negative expectations about DMB. The reason why two opposite expectations exist is that DMB does not come out from customer's need but from technology development. Therefore, customers might have hard time to interpret the real meaning of DMB. Time is quite critical to a high tech product, like DMB because another product with same function from different technology can replace the existing product within short period of time. If DMB does not positioning well to customer's mind quickly, another products like Wibro, IPTV, or HSPDA could replace it before it even spreads out. Therefore, positioning strategy is critical for success of DMB product. To make correct positioning strategy, one needs to understand how consumer interprets DMB and how consumer's interpretation can be changed via communication strategy. In this study, we try to investigate how consumer perceives a new product, like DMB and how AD strategy change consumer's perception. More specifically, the paper segment consumers into sub-groups based on their DMB perceptions and compare their characteristics in order to understand how they perceive DMB. And, expose them different printed ADs that have messages guiding consumer think DMB in specific ways, either cellular phone or personal TV. Research Question 1: Segment consumers according to perceptions about DMB and compare characteristics of segmentations. Research Question 2: Compare perceptions about DMB after AD that induces categorization of DMB in direction for each segment. If one understand and predict a direction in which consumer perceive a new product, firm can select target customers easily. We segment consumers according to their perception and analyze characteristics in order to find some variables that can influence perceptions, like prior experience, usage, or habit. And then, marketing people can use this variables to identify target customers and predict their perceptions. If one knows how customer's perception is changed via AD message, communication strategy could be constructed properly. Specially, information from segmented customers helps to develop efficient AD strategy for segment who has prior perception. Research framework consists of two measurements and one treatment, O1 X O2. First observation is for collecting information about consumer's perception and their characteristics. Based on first observation, the paper segment consumers into two groups, one group perceives DMB similar to Cellular phone and the other group perceives DMB similar to TV. And compare characteristics of two segments in order to find reason why they perceive DMB differently. Next, we expose two kinds of AD to subjects. One AD describes DMB as Cellular phone and the other Ad describes DMB as personal TV. When two ADs are exposed to subjects, consumers don't know their prior perception of DMB, in other words, which subject belongs 'similar-to-Cellular phone' segment or 'similar-to-TV' segment? However, we analyze the AD's effect differently for each segment. In research design, final observation is for investigating AD effect. Perception before AD is compared with perception after AD. Comparisons are made for each segment and for each AD. For the segment who perceives DMB similar to TV, AD that describes DMB as cellular phone could change the prior perception. And AD that describes DMB as personal TV, could enforce the prior perception. For data collection, subjects are selected from undergraduate students because they have basic knowledge about most digital equipments and have open attitude about a new product and media. Total number of subjects is 240. In order to measure perception about DMB, we use indirect measurement, comparison with other similar digital products. To select similar digital products, we pre-survey students and then finally select PDA, Car-TV, Cellular Phone, MP3 player, TV, and PSP. Quasi experiment is done at several classes under instructor's allowance. After brief introduction, prior knowledge, awareness, and usage about DMB as well as other digital instruments is asked and their similarities and perceived characteristics are measured. And then, two kinds of manipulated color-printed AD are distributed and similarities and perceived characteristics for DMB are re-measured. Finally purchase intension, AD attitude, manipulation check, and demographic variables are asked. Subjects are given small gift for participation. Stimuli are color-printed advertising. Their actual size is A4 and made after several pre-test from AD professionals and students. As results, consumers are segmented into two subgroups based on their perceptions of DMB. Similarity measure between DMB and cellular phone and similarity measure between DMB and TV are used to classify consumers. If subject whose first measure is less than the second measure, she is classified into segment A and segment A is characterized as they perceive DMB like TV. Otherwise, they are classified as segment B, who perceives DMB like cellular phone. Discriminant analysis on these groups with their characteristics of usage and attitude shows that Segment A knows much about DMB and uses a lot of digital instrument. Segment B, who thinks DMB as cellular phone doesn't know well about DMB and not familiar with other digital instruments. So, consumers with higher knowledge perceive DMB similar to TV because launching DMB advertising lead consumer think DMB as TV. Consumers with less interest on digital products don't know well about DMB AD and then think DMB as cellular phone. In order to investigate perceptions of DMB as well as other digital instruments, we apply Proxscal analysis, Multidimensional Scaling technique at SPSS statistical package. At first step, subjects are presented 21 pairs of 7 digital instruments and evaluate similarity judgments on 7 point scale. And for each segment, their similarity judgments are averaged and similarity matrix is made. Secondly, Proxscal analysis of segment A and B are done. At third stage, get similarity judgment between DMB and other digital instruments after AD exposure. Lastly, similarity judgments of group A-1, A-2, B-1, and B-2 are named as 'after DMB' and put them into matrix made at the first stage. Then apply Proxscal analysis on these matrixes and check the positional difference of DMB and after DMB. The results show that map of segment A, who perceives DMB similar as TV, shows that DMB position closer to TV than to Cellular phone as expected. Map of segment B, who perceive DMB similar as cellular phone shows that DMB position closer to Cellular phone than to TV as expected. Stress value and R-square is acceptable. And, change results after stimuli, manipulated Advertising show that AD makes DMB perception bent toward Cellular phone when Cellular phone-like AD is exposed, and that DMB positioning move towards Car-TV which is more personalized one when TV-like AD is exposed. It is true for both segment, A and B, consistently. Furthermore, the paper apply correspondence analysis to the same data and find almost the same results. The paper answers two main research questions. The first one is that perception about a new product is made mainly from prior experience. And the second one is that AD is effective in changing and enforcing perception. In addition to above, we extend perception change to purchase intention. Purchase intention is high when AD enforces original perception. AD that shows DMB like TV makes worst intention. This paper has limitations and issues to be pursed in near future. Methodologically, current methodology can't provide statistical test on the perceptual change, since classical MDS models, like Proxscal and correspondence analysis are not probability models. So, a new probability MDS model for testing hypothesis about configuration needs to be developed. Next, advertising message needs to be developed more rigorously from theoretical and managerial perspective. Also experimental procedure could be improved for more realistic data collection. For example, web-based experiment and real product stimuli and multimedia presentation could be employed. Or, one can display products together in simulated shop. In addition, demand and social desirability threats of internal validity could influence on the results. In order to handle the threats, results of the model-intended advertising and other "pseudo" advertising could be compared. Furthermore, one can try various level of innovativeness in order to check whether it make any different results (cf. Moon 2006). In addition, if one can create hypothetical product that is really innovative and new for research, it helps to make a vacant impression status and then to study how to form impression in more rigorous way.

  • The practical application of modern space science and technology have resulted in many actual and potential gains of mankind. These successes have conditioned and increased the need for a viable space law regime and the challenge of space has ultimately led to the formation of an international legal regime for space. Space law is no longer a primitive law. It is a modern law. Yet, in its stages of growth, it has not reached the condition of perfection. Therefore, under the existing state of thing, we could carefully say that the space law is one of the most newest fields of jurisprudence despite the fact that no one has so far defined it perfectly. However, if space law can be a true jurisprudential entity, it must be definable. In defining the space law, first of all, the grasp of it's nature iis inevitable. Although space law encompasses many tenets and facets of other legal discriplines, its principal nature is public international law, because space law affects and effects law relating intercourse among nations. Since early 1960s when mankind was first able to flight and stay in outer space, the necessity to control and administrate the space activities of human beings has growingly increased. The leading law-formulating agency to this purpose is the United Nation's ad hoc Committee on Peaceful Uses of Outer Space("COPUOS"). COPUOS gave direction to public international space law by establishing the 1963 Declaration of Legal Principles Governing the Activities of the States in the Exploration and Use of Outer Space("1963 Declaration"). The 1963 Declaration is very foundation of the five international multilateral treaties that were established successively after the 1963 Declaration. The five treaties are as follows: 1) The Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space including Moon and other Celestial Bodies, 1967. 2) The Agreement on the Rescue of Astronauts, the Return of Astronauts, and the Return of Objects Launched into Outer Space, 1968. 3) The Convention on International Liability for Damage Caused by Space Objects, 1972. 4) The Convention on Registration of Objects Launched into Outer Space, 1974. 5) The Agreement Governing Activities of States on the Moon and Other Celestial Bodies: Moon Treaty, 1979. The other face of space law is it's commercial aspect. Space is no longer the sole domination of governments. Many private enterprise have already moved directly or indirectly into space activities in the parts such as telecommunications and space manufacturing. Since space law as the public international law has already advanced in accordance with the developments of space science and technology, there left only a few areas untouched in this field of law. Therefore the possibility of rapid growth of space law is expected in the parts of commerical space law, as it is, at this time, in a nascent state. The resources of the space environment are also commercially both valuable and important since the resources include the tangible natural resources to be found on the moon and other celestial bodies. Other space-based resources are solar energy, geostationary and geosynchronous orbital positions, radio frequencies, area possibly suited to human habitations, all areas and materials lending themselves to scientific research and inquiry. Remote sensing, space manufacturing and space transportation services are also another potential areas in which commercial. endeavors of Mankind can be carried out. In this regard, space insurance is also one of the most important devices allowing mankind to proceed with commercial space venture. Thus, knowlege of how space insurance came into existence and what it covers is necessary to understand the legal issues peculiar to space law. As a conclusion the writer emphasized the international cooperation of all nations in space activities of mankind, because space commerce, by its nature, will give rise many legal issues of international scope and concern. Important national and world-community interests would be served over time through the acceptance of new international agreements relating to remote sencing, direct television broadcasting, the use of nuclear power sources in space, the regularization of the activities of space transportation systems. standards respecting contamination and pollution, and a practical boundary between outer space and air space. If space activity regulation does not move beyond the national level, the peaceful exploration of space for all mankind will not be realized. For the efficient regulation on private and governmental space activities, the creation of an international space agency, similar to the International Civil Aviation Organization but modified to meet the needs of space technology, will be required. But prior to creation of an international organization, it will be necessary to establish, at national level, the Office of Air and Space Bureau, which will administrate liscence liscence application process, safety review and sale of launch equipment, and will carry out launch service.

  • 1957년 이래 1999년 8월까지 약 313회의 우주발사 실패가 있었다. NASA의 '우주수송을 발전시킨다'라는 목표하에서, 제6의 목적은 우주선의 사고발생위험을 10년내에 1/40으로, 25년내에 1/140으로 낮춘다는 것이다. 이는 곧 우주개발이 아직도 얼마나 위험한 것인가를 보여주는 통계자료이다. 왜 이렇게 위험한 우주여행을 감수하면서, 우주개발에 뛰어드는 것인가? 우주개발은 경제적인 측면에서 인공위성을 이용한 통신 및 방송산업은 21세기 초에이룩될 우주산업의 가장 큰 분야가 될 전망이다. 특히, 우주의 특수한 환경인 무중력상태와 지구상보다 1,000 배나 높은 진공상태를 이용한 새로운 반도체의 개발 및 생산 그리고 신약의 개발 등이 활발하게 이루어질 것인데, 지난 1986년부터 지난달까지 운용되던 러시아의 "미르" 우주정거장에서는 수정을 생산하여 판매 하였다. 현재 우주산업은 미국, EU, 일본 등 소수 선진국들이 주도하고 있으며, 세계우주산업 시장규모는 년 평균 10% 이상 지속적인 신장이 이루어질 것으로 전망하고 있으며, 특히 민간용 이동통신산업 확대, 우주탐사활동 증대, 우주정거장사업 추진등으로 우주산업 규모는 비약적으로 신장할 것으로 예측되며, 최근 5년간 ED와 일본은 연평균 15${\sim}$20 %의 고성장을 유지하고 있다. 미국 NASA가 1993년 가을부터 1996년 10월까지 3년동안 민간기업에 기술을 이전한 결과를 보면, 거시적 안목을 가지고 우주산업을 추진해야 함을 알 수 있다. NASA는 미국 전역에서 16,300개의 일자리를 창출하였으며, NASA 의 기술 이전으로 새로 생긴 상품은 938개에 달하며, NASA가 민간에 이전한 기술을 경제적 가치로 환산하면 매년 16억 달러에 달하며, 또한 기술지원을 받은 미국기업을 5,600개가 넘는다. 또한, 경제외적인 측면에서 국가의 안보, 자주국방을 위한 정보수집을 위해 결정적인 역할을 한다. 우리나라는 외국에서 발사한 7개의 위성을 운영하고 있으며, '03년 8월 8일 고흥 외나로도에 인공위성발사장 기공식을 함으로써, 국내우주개발계획에 박차를 가하고 았다. 이러한 국가적인 우주개발계획과 함께 공군의 우주력건설에 따른 고찰이 필요하다. 우리나라는 미국과의 MTCR 협의로 인하여, 사정거리 300km 이상의 미사일발사체를 개발하지 않도록 되어 있으므로, 현실적으로 국방부(공군) 자체에서 우주발사체를 개발하는 것은 어렵다. 현대전에서 항공우주력은 곧 전쟁의 승패를 결정하는 필수적인 요소이며, 이미 전장이 우주로 화대되어 있는 현실에 있어서, 군의 우주력건설은 '우주력건설의 당위성'을 논할 때가 아니고, '어떻게 군의 우주력건설'을 하여야 하는 가 '우주력건설의 방법론'에 대한 구체적인 연구가 되어야 할 때이다. 우주의 군사적이용에 대한 제한은 미국의 주장대로 "비침략적 이용(non-aggressive use)"이 옳은 판단이며, 구소련의 "비군사적 이용(non-military)"에 대한 주장은 옳지 않다. 이러한 구 소련의 주장은 러시아정부에서는 적극적으로 주장하고 있지도 않고 현실성도 없는 주장이다. 따라서, 미국의 우주의 평화적 이용에 대한 개념에 의하면, 다목적위성의 군정찰목적으로의 이용이나, 상업위성의 군통신 이용은 자유롭다고 할 것이다. 즉, 공군은 군정찰위성, 통신위성 개발을 민간연구부서와 자유롭게 할 수 있다고 본다, 다만, 미국과의 MTCR 협정상 우주발사체 개발에 대해서는 제한을 받고 있으나, 우주발사체개발은 한국항공우주연구원에 위임하고, 궤도에 있는 위성을 운용하면 문제가 없다고 본다. 다목적위성은 주 임무가 Remote Sensing 인데 High resolution 특히 SAR 센서는 주로 군사목적으로 이용되고 있다. 따라서, 다목적위성은 공군과 한국항공우주연구원, 국방과학연구소간의 공동으로 연구개발을 할 수 있는 제도가 마련되어야 한다. 미 공군도 현재 사용 중인 발사체를 단계적으로 제거하며 기업 발사체 이용을 증가시킨다. 또한, 군 통신의 특수성 때문에 민수용 통신 및 방송 서비스와는 독립적으로 운영되어 왔으나 군 통신 중계기와 민간 통신 중계기가 혼합되어 운용됨으로써 군 위성 통신의 단독에서 오는 경제적인 부담을 줄이기 위한 방안으로 각광을 받고 있다. 걸프전에서도 미국은 상용통신위성을 군 통신에 사용하였다. 우리나라의 우주과학기술 연구에의 착수는 다른 나라들과의 경제적 개발 정도와 비교해 볼 때 늦었으며, 우주개발예산 또한 상대적으로 일본은 2조원/년인데 비하여 우리는 5조원/15년으로 부족하다. 우주산업은 산업의 특성상 초기 육성기간은 산업체 수익사업으로 전개될 수 없으므로, 정부예산에 의한 사업추진이 불가피하다. 외국의 경우에도 우주개발 프로그램은 모두 정부사업이며, 최근 들어 통신 방송위성 등 극히 제한된 분야에 한해 민간사업이 추진되고 있을 뿐이다. 더욱이 우리나라와 같이 우주산업이 초창기에 있는 경우에는 이러한 필요성이 더욱 절박하며, 정부사업의 추진 시에도 정부지원예산의 회수를 전제로 하지 않는 정부출현 혹은 투자사업으로 추진되어야하는 것이 필수적 요소이다. 우주연구인력수준에 있어서도, 세계적으로 우주개발선전국들에 비하여 예산이 부족하며, 전문인력도 부족하다. 따라서, 국가 우주개발의 효율적이고 체계적인 추진과 사업 추진시의 힘의 분산 및 혼돈을 방지하기 위해서도 한국의 우주개발 체계에 대한 선명한 제시와 함께 국내 우주개발 관련 법령의 제정이 시급하다. 또한, 우리나라 우주개발은 각기다른 법령하에 각기 다른 주무부처에서 사업을 진행하고 있으므로, 국가적으로 집중적인 우주개발체제를 확립하는 것이 필요하다. 우주력건설을 위해서는 항공우주연구분야 즉 국방과학연구소와 한국항공우주연구원의 항공우주분야를 어떻게 협력 또는 통합하느냐에 대한 연구이전에, 우주력을 어떻게 운용할 것인가에 대한 근본적인 전략과 정책을 수립할 '우주작전본부'를 공군에 설립하는 것이 선과제이다.'우주작전본부'를 설립하기 위해서는 무엇보다도 국방부와 합참의 전략적인 의사결정이 필요하다. 특히, 일본의 군의 우주력건설에 대한 계획을 참고하여, 자주국방을 위한 최소한의 군사목적의 정찰위성, 통신위성, 우주감시체계의 확보가 필요하다. MTCR협정 등의 문제를 해결하기 위해서는 한국항공우주연구원의 발사체개발을 이용하고, 또한 다목적위성, 통신위성개발을 활용하기 위하여 국방예산을 확보하여야 하겠으며, 우선적으로 일본의 정찰위성 운용예산인 약 2조 5천억원정도의 우주예산을 국방부에서 먼저 확보할 필요가 있다.

  • The purpose of this study is to provide the basic materials for searching the way of improvement to heighten the emergency medical welfare level by one step further. To achieve this purpose, the subjects of this study were selected 452 college students in Gwangju, using a random sampling method. The statistical analysis methods utilized for analyzing the collected data are frequency analysis, $x^2$ test. The conclusions obtained from these analyses are as following ; 1. In question about necessary optimum number of persons for rescue first aid activity, health and non-health major college students responded by 39.2%, 45.3% respectively that rescue team 15 people, first aid team 3 people is most suitable. But there was no significant difference in major department(p<0.05). 2. In question about security of the public health doctor and the emergency medical technician, all health and non-health major college students are recognizing necessity urgently, but there was no significant difference in major department(p<0.05). 3. In question about 119 rescue first aid team member applying for an examination qualification grant to the department of EMT's graduate, all health and non-health major college students were highest by 52.9%, 52.4% respectively in "necessity" item. But there was no significant difference in major department(p<0.05). 4. Because rescue first aid equipment level appears higher than 41.7% in non-health major college student's case by 54.2% in health major college student's case, health major college students are recognizing that equipment level should be supplemented more but there was no significant difference in major department(p<0.05). 5. In question about equipment supplement, all health and non-health major college students appeared highest by 64.8%, 69.3% in accident type different special equipment. But there was no significant difference in major department(p<0.05). 6. In question about rescue ambulance car size, we could know being thinking that health and non-health major college student each 61.2%, 56.5% is small and narrow that large size of the rescue ambulance amount need. But there was no significant difference in major department(p<0.05). 7. In question about patient's state is worsened, because rescue first aid equipment is inferior, health major college student responded sometimes 55.1%, many 29.5%. very many by 11.5%, while non-health major college student responded 65.8%, 23.1%, 4.0% respectively. There was significant difference in major department(p<0.05). 8. In question about emergency patient must utilize for 119 rescue ambulance car, all health and non-health major college students appeared highest by 38.8%, 41.3% in "not so" item. In question about rescue first aid team's first-aid treatment ability improves more, all health and non-health major college students appeared highest by 58.1% and 58.7% respectively in "improve" item. In question about "119 rescue ambulance car must go more rapidly than now", all health and non-health major college students are recognizing that should be quicker by 58.1%, 60.9% respectively. When called to 119 all health and non-health major college students responded highest by 55.5%, 53.3% respectively that we must receive first-aid treatment direction from a doctor. In question about "119 rescue ambulance car must be made the pay system", all health and non-health major college students responded 74%, 80% respectively in "not so" item. There was significant difference in major department(p<0.05). In conclusions, In oder to provide superior rescue first aid service to people, a public health doctor should be placed in the situation room inside the fire station so that the doctor could instruct the proper emergency treatment suitable for each situation to the rescue first aid team. Also, national education about a first-aid treatment that do to all people is necessarily necessary in emergency delivery system and this should be spread extensively through school education and broadcasting medium and education should be gone side by side, and see that will can save emergency patients' life which is more when these education consists continuously fixed period for public institution of policeman, fire officer etc. specially. And for reinforcement of patient transfer system, public organization must procure special ambulance car so that emergency patient receive first aid treatment while transfer.

  • 본 연구는 1966년 TBC 동화부의 황금박쥐로 시작된 한국 하청애니메이션의 역사를 1980년대 시기까지 분석하여, 한국애니메이션에서 30년 넘게 진행되어 온 하청애니메이션의 역사를 재조명하였다. 이를 위해 하청애니메이션 제작사 제작현황 산업의 규모 등 하청애니메이션 개괄적인 상황을 통해 당시 OEM산업의 실태를 점검하였고, 애니메이션이 하청제작산업으로 고착화된 배경을 시대상황과 연계하여 분석하였다. 또한 이를 기반으로 하청애니메이션산업이 발생시킨 문제점과 한계 그리고 이를 극복하고 창작애니메이션을 활성화하기 위한 새로운 모색에 대한 분석을 통해 애니메이션 역사 연구의 지평을 넓혀보고자 하였다. 1970년대는 중화학공업 육성과 수출주도형 경제성장이 국가적 목표였던 시기였다. 70년대 후반부터 애니메이션도 해외애니메이션 하청 수주를 통해 수출 주력산업으로 주목받았다. 하청 해니메이션 제작의 확대는 당시 대중문화에 대한 국가의 정책과 칼라TV보급, 비디오 제작 시장 활성화 등의 매체 변화로 극장용 애니메이션 관객이 축소된 점에도 영향을 받았으며 경제적 논리로 자체 애니메이션 제작을 기피했던 방송사 등 플랫폼 부재도 그 원인이었다. 하청애니메이션산업은 애니메이션 인프라의 구축과 신진 인력 양성 등 애니메이션 환경을 확장시켰다는 측면에서 긍정적인 평가를 할 수 있다. 그러나 기술집약적인 '프로덕션' 단계 중심의 발전은 기획력 등 '프리 프로덕션'의 부재와 '포스트 프로덕션(후반작업)'에 대한 인식 부족으로 전문인력 양성에 왜곡된 구조를 만들었고, OEM산업으로 축적된 자본을 창작애니메이션 제작에 재투자하여 내수시장을 형성하지 못한 점은 부정적 측면으로 평가된다. 애니메이션은 한 나라의 문화적, 정신적 산물이다. 따라서 전문인력의 양성과 우수한 작품의 창작, 선순환 구조를 만들 수 있는 시장의 형성 등 창작애니메이션 활성화를 위한 체계적인 지원 정책이 모색되어야 한다. 그러나 애니메이션은 산업이지만 하드웨어 중심의 제조업이 아닌 창의력에 기반한 문화산업이라는 인식은 없었다. 이러한 인식의 부재로 이 시기 한국 애니메이션은 독자적인 작품 제작을 위한 장기적인 계획과 투자를 통해 시장을 만들고, 창작애니메이션을 활성화하는 어떠한 정책 방안도 마련하지 못했다. 이러한 시도는 1990년대 이후 한국도 창작 애니메이션 보호 육성을 위한 다각적인 모색을 통해 새롭게 시작된다.

  • 아이폰의 등장과 함께 스마트 폰에 대한 관심이 높아지고, 통신사업자를 통해야만 가능했던 다양한 서비스가 스마트 폰을 통해서 직접 제공할 수 있는 환경이 가능해졌다. 전세계적으로 해외 관광객이 증가하면서 관광가이드 없이 자신의 노력으로 여행을 다니는 개인관광객도 증가하고 있다. 그러나 우리나라를 방문하는 외국인들이 개인적으로 여행을 즐기기에는 언어소통이나 제공되는 정보의 부족으로 어려움을 느끼고 있다. 본 연구에서는 스마트 폰이 탑재하고 있는 GPS와 WiFi 또는 3G 무선망을 통해서 사전에 설정된 관광 정보 카테고리에 따라서 관광객의 위치에 따른 관련 정보를 자동으로 제공함으로써 관광객의 편의성을 높이는 서비스 기술을 개발하였다. 개발된 서비스는 인사동을 대상으로 시험하였으며, 사용자의 선택과 같은 불편함 없이 주변정보를 제공함으로써 관광에 대한 편의성을 최대한 높였다.
