  • 통일 시기에 대순진리회 3대 중요사업인 구호자선·사회복지·제반 교육사업을 어떻게 추진할 것인가가 이 논문의 핵심 주제다. 3대 중요사업은 통일 이후에도 반드시 추진되어야 하는바, 해원상생사상의 실천에 기반하기 때문이다. 해원상생의 인존사상은 유엔헌장의 서문과 세계평화를 지향한다는 점에서 일맥상통하다. 북한의 주민은 피폐된 경제 하에서 기아에 허덕이고 있는데 통일 시기 의식주의 위기를 맞이할 것이 분명하다. 본 연구에서는 3대 중요사업의 추진 여건을 분석하기 위하여 독일의 평화통일, 예멘의 급변사태 통일, 베트남의 무력통일 사례를 진단하였다. 3가지 통일유형은 공통적으로 3대 중요사업을 수행하는데 상당한 예산과 지원을 소요케 하였는데, 특히, 급변사태 후 무력충돌과 무력통일 시에는 수많은 인명의 살상과 인프라의 파괴로 구호와 의료지원 등 의식주 문제 해결이 시급하였다. 한편, 3대 중요사업의 방안을 도출하기 위하여 유엔난민기구(UNHCR)의 모델을 분석하였는바, 정신력과 전문성을 갖춘 전문 인력의 확충, 복합적인 상황 대비 능력을 갖춘 표준적인 조직의 편성과 명확한 과업 부여, 충분한 구호물품과 예산 준비, 접경지역과 북한지역의 거점 확보, 물류 창고와 수송수단 확보, 후원금 수급을 위한 네트워크 구축 등의 시사점을 도출하였다. 이를 바탕으로 통일시기와 북한지역 상황을 고려하여 통일대비 3대 중요사업의 체계구축 분야 세부과제 8개 항과 실행대비 검토과제 9개 항을 제시하였다. 결론적으로 통일시기 3대 중요사업은 그 당위성 측면에서 소홀함이 없어야 하며, '통일시기 3대 중요사업 추진방안' 제하의 매뉴얼에 3대 중요사업 추진의의, 조직 구성 및 임무, 통일시기 예상 상황, 전진기지 및 거점 운용, 경비 및 물류 준비, 파견팀 편성 및 운용, 홍보 및 대외협력, 전문 인력 양성, 안전조치, 수송 및 연락체계 등이 포함되어야 할 것이다.

  • 세계적으로 전파력과 병원성이 높은 신종인플루엔자, 조류독감 등과 같은 전염병이 증가하고 있다. 전염병이란 특정 병원체(pathogen)로 인하여 발생하는 질병으로 감염된 사람으로부터 감수성이 있는 숙주(사람)에게 감염되는 질환을 의미한다. 전염병의 병원체는 세균, 스피로헤타, 리케차, 바이러스, 진균, 기생충 등이 있으며, 호흡기계 질환, 위장관 질환, 간질환, 급성 열성 질환 등을 일으킨다. 전파 방법은 식품이나 식수, 곤충 매개, 호흡에 의한 병원체의 흡입, 다른 사람과의 접촉 등 다양한 경로를 통해 발생한다. 전 세계의 대부분 국가들은 전염병의 전파를 예측하고 대비하기 위해서 수학적 모델을 사용하고 있다. 하지만 과거와 달리 현대 사회는 지상과 지하 교통수단의 발달로 전염병의 전파 속도가 매우 복잡하고 빨라졌기 때문에 우리는 이를 예방하기 위한 대책 마련의 시간이 부족하다. 그러므로 전염병의 확산을 막기 위해서는 전염병의 전파 경로를 예측할 수 있는 시스템이 필요하다. 우리는 이러한 문제를 해결하기 위해서 전염병의 실시간 감시 및 관리를 위한 전염병의 감염 경로 추적 및 예측이 가능한 통합정보 시스템을 구현하였다. 이 논문에서는 전염병의 전파경로 예측에 관한 부분을 다루며, 이 시스템은 기존의 수학적 모델인 Susceptible - Infectious - Recovered (SIR) 모델을 기반으로 하였다. 이 모델의 특징은 교통수단인 버스, 기차, 승용차, 비행기를 포함시킴으로써, 도시내 뿐만 아니라 도시간의 교통수단을 이용한 이동으로 사람간의 접촉을 표현할 수 있다. 그리고 한국의 지리적 특성에 맞도록 실제 자료를 수정하였기 때문에 한국의 현실을 잘 반영할 수 있다. 또한 백신은 시간에 따라서 투여 지역과 양을 조절할 수 있기 때문에 사용자가 시뮬레이션을 통해서 어느 시점에서 어느 지역에 우선적으로 투여할지 백신을 컨트롤할 수 있다. 시뮬레이션은 몇가지 가정과 시나리오를 기반으로 한다. 그리고 통계청의 자료를 이용해서 인구 이동이 많은 주요 5개 도시인 서울, 인천국제공항, 강릉, 평창, 원주를 선정했다. 상기 도시들은 네트워크로 연결되어있으며 4가지의 교통수단들만 이용하여 전파된다고 가정하였다. 교통량은 국가통계포털에서 일일 교통량 자료를 입수하였으며, 각도시의 인구수는 통계청에서 통계자료를 입수하였다. 그리고 질병관리본부에서는 신종인플루엔자 A의 자료를 입수하였으며, 항공포털시스템에서는 항공 통계자료를 입수하였다. 이처럼 일일 교통량, 인구 통계, 신종인플루엔자 A 그리고 항공 통계자료는 한국의 지리적 특성에 맞도록 수정하여 현실에 가까운 가정과 시나리오를 바탕으로 하였다. 시뮬레이션은 신종인플루엔자 A가 인천공항에 발생하였을 때, 백신이 투여되지 않은 경우, 서울과 평창에 각각 백신이 투여된 경우의 3가지 시나리오에 대해서, 감염자가 피크인 날짜와 I (infectious)의 비율을 비교하였다. 그 결과 백신이 투여되지 않은 경우, 감염자가 피크인 날짜는 교통량이 가장 많은 서울에서 37일로 가장 빠르고, 교통량이 가장 적은 평창에서 43일로 가장 느렸다. I의 비율은 서울에서 가장 높았고, 평창에서 가장 낮았다. 서울에 백신이 투여된 경우, 감염자가 피크인 날짜는 서울이 37일로 가장 빨랐으며, 평창은 43일로 가장 느렸다. 그리고 I의 비율은 강릉에서 가장 높으며, 평창에서 가장 낮았다. 평창에 백신을 투여한 경우, 감염자가 피크인 날짜는 37일로 서울이 가장 빠르고 평창은 43일로 가장 느렸다. I의 비율은 강릉에서 가장 높았고, 평창에서는 가장 낮았다. 이 결과로부터 신종인플루엔자 A가 발생하면 각 도시는 교통량에 의해 영향을 받아 확산된다는 것을 확인할 수 있다. 따라서 전염병 발생시 전파 경로는 각 도시의 교통량에 따라서 달라지므로, 교통량의 분석을 통해서 전염병의 전파 경로를 추적하고 예측함으로써 전염병에 대한 대책이 가능할 것이다.

  • Khori(高麗) refers to the Chaabog(reindeer) that live on lichens(蘚) on Mt. Soyon(鮮) in which pastures are the cold and dry plateau of North Eurasia. Thus, the origin region of the Khori or Koguryo that are the ancestors of the reindeer-herding pastoral nomads(馴鹿 遊牧民) can be said to be the Steppe-Taiga-Tundra pastoral areas of North Eurasia and North America. When the pastoral nomads moved on to the great mountain(大山) zone of the Jangbaek(長白) to the Baekdu(白頭) Mountains, they could have been in contact with pastoral farmers or agricultural farmers living there and they became the farmers remaining on agricultural farms. They were the Koryo people, the ancestors of Korea. Staying in one place, they gradually forgot the origin of their reindeer-herding pastoral nomadic history in the Northwest area of Mt. Soyon, the small mountain(小山) zone of the Steppe-Taiga-Tundra pastoral areas. In other words, they lost their identity as reindeer-herding pastoral nomads when they entered the agricultural area after leaving the pastoral area. However, since their basic genes had already formed when they lived on the cold and dry plateau of North Eurasia, it is possible to study their pastoral nomadic history focusing on 'the minority living in the broad area(廣域少數)', by utilizing highly advanced biotechnological science and focusing on genes and information technology innovation, and removing various past hindrances in research. Therefore, it is not so difficult to restore the reindeerherding pastoral nomadic history of the Koguryo(高句麗) people and secure their pastoral nomadic identity, of which the first steps have already been taken into their historical stages. The Eurasian continent and the Korean peninsula, especially the cold and dry plateau of North Eurasia and the Korean peninsula have been closely related to each other ecologically and historically. They can never be a separate space at all. The Eurasian continent lies horizontally east to west and thus, the continent forms an isothermal zone. Also, since the time of producing their own foods, it was relatively easy for people with their technology to move to other places owing to the pastoral nomadic characteristic of mobility. Unlike the Chungyen(中原) region, western Asia and the regions covering the Siberia-Manchu-Korean peninsula where food production revolution was first made were connected to the Mongolian lichens route(蘚苔之路: Ni, ukinii jam) and steppe roads. Although the ecological conditions of nature have changed a bit throughout a long history, it was natural for the many tribes in North Asia living on the largest Steppe-Taiga-Tundra area in the world to have believed 'the legends related to animals in relation to their founders and ancestors(獸祖傳說)'. Assuming that Siberian tigers and the tigers living on Mt. Baekdu were connected ecologically and genetically because of the ecological characteristics of the animals, and their migration from plateau to plateau, we would suspect that the Chosun(朝鮮) tribe living on Mt. Baekdu were ethnically and culturally more closely connected to the farther removed Ural-Altai tribes that lived on the cold and dry plateau region than to the Han(i14;) tribe who lived in Chungyen(中原) that was close to Mt. Baekdu. More evidence is the structure of the Korean language which has the form of 'Subject + Object + Verb', which is assumed to have originated from the speedy lifestyle of the reindeer-herding pastoral nomads. The structure is quite different from that of the Han(漢) language, which is based on agricultural life. Also, it is natural for reindeer riding reindeerherding pastoral nomads or horse-riding sheep-herding pastoral nomads(騎馬, 羊遊牧民) to have held military and political power over the region and eventually to have established an ancient pastoral nomadic empire in the process of their conquest of agricultural regions. The stages for founding global empires in the history of mankind maybe largely divided into two, in terms of ecological conditions and occupations. They are the steppes and the oceans. Of course, the steppe-based empires were established based on the skills to deal with horses and the ability to shoot arrows while riding horses, along with the use of iron ware in the 8th century BC. The steppe-based empires became the foundation for an oceanic empire, which could have been established by the use of warships and warship guns since the 15th Century. Based on those facts, we know that Chosun, Puyo(夫餘), and Koguryo are the products of a developmental process of pastoral nomadic empires on the steppes. Maybe we can easily find the pastoral nomadic identity of the Koguryo more than we expected when we trace the origins and history of the Korean tribe living in the pastures located in the northwest area of Mt. Jangbaek by focusing on pastoral nomadic mobility and organization just as we have investigated the historic origins of Anglo-Saxons in America by focusing on the times before the 15th Century. In the process, we should keep in mind that English culture originated from the Industrial Revolution and was directly delivered to the American continent, although America was far from England and was not an intermediate point on long sojourns either. Further, American culture came back to England in a more advanced form later. The most important thing currently to be resolved is to cause Koreans to look back on their own history in a freer way of thinking and with diverse, profound, and sharp insight, taking away the old and existing conventional recognition that is entangled with complicated interests with Korean people and other countries. The meanings of Chosun, Khori, and Solongos have been interpreted arbitrarily without any historic evidence by the scholars who followed conventional tradition of fixed-minded aristocrats in an agricultural society. If the Siberian cultural properties of the stone age, the earthenware age, the bronze age, and the iron age are analyzed in such a way, archaeological discovery will never be able to contribute to the restoration of the Koguryo's pastoral nomadic identity. One should transcend the errors that tend to interpret the cultural properties discovered in the pastoral nomadic regions as not being differentiated from those of agricultural regions and just interpret them altogether from the agricultural point of view. A more careful intention is required in the interpretation of cultural properties of ancient Korean empires that seem to have been formed due to mutual interactions of pastoral nomadic and agricultural cultures. Also, it is required that the conventional recognition chain of 'reverse-genes' be severed, which has placed more weight on agricultural properties than pastoral nomadic ones, since their settlement on agricultural farms was made after the establishment of their ancient pastoral nomadic empires. There is no reason at all to place priority on stoneware, earthenware, bronze ware, and iron ware than on wooden ware(木器) and other ware which were made of animal skins(皮器), bones and horns(骨角器), in analyzing the history in the regions of reindeer or sheep pastures. Reading ancient Korean history from the perspective of pastoral nomadic history, one feels strongly the instinctive emotions to return to the natural 'mother place'. The reindeer-herding pastoral nomadic identity of the Koguryo people that has been accumulated in volumes in their genes and hidden deep inside and have interacted organically could be reborn with Burqanism(Burqan refers to 不咸 in Chinese), which was their religion by birth and symbolized as the red willow(紅柳=不咸). The mother place of the Koguryo's people is the endless vast green pastures of North Eurasia and North America, where we anticipated the development of Korean livestock farming following the inherent properties in the genes of the reindeer-herding pastoral nomads with Korean ancestors. We anticipate that the place would be the core resource that could contribute to the development of life of living creatures following the inherent properties of their genes and biotechnological factors. In other words, biotechnology used for a search for clues on the well-being of humans could be the fruit brought by Burqanism of the Koguryo people and the fruit of the globalization of Korean livestock farming. It is the Chosun farmer in China come from the vast nomadic reindeer pastures of North Eurasia that resolved the food problem of a billion Chinese people with lowland paddy rice seeds (水稻) by transforming Heilongjiang Province(黑龍江省) into an oceanic lowland paddy rice field(水田). Even Mao Tse-tung(毛擇東) could not resolve the food problem by his revolution campaigns for tens of years. Today is the very time that requires the development of special livestock farming following the inherent properties of the ancient Korean reindeer-herding pastoral nomads that respected the dignity of life on the cold and dry plateau of North Eurasia and the America continent. I suggest that research should be started from the pastures of the Dariganga Steppe in East Mongolia that was the homeland of Hanwoo(韓牛) and the central horse-herding steppe place(牧馬場) of Chingis Khan's Mongolia. The Dariganga Steppe is awash with an affluent natural environment for pastoral nomadic living however, the quality of life of the pastoral nomads there is still low. I suggest we Koreans, the descendents of the Koguryo, should take our first steps for our livestock farming business project and develop the Northern nomadic pastures, here at the pastures of the Dariganga Steppe, which is the Mongolian core place of state-of-the-art technology for military weapons.

  • This study was carried out to identify the difference between nursing needs and levels of satisfaction of primiparae during the early postpartum period. The goal of the study was to obtain data needed to develope maternal education programs and to improve the nursing quality for primipara. The subjects were 111 primiparae who had normal delivery at 2 general hospitals in the Seoul area. The data was gathered using an 81 items questionnaire which was developed by the researcher from Nov. 30, 1995 to Feb. 5, 1996. Results found are as follows : 1. The characteristics of subjects : The majority of subjects were aged 26-30yrs(60.4%), high school graduated(49.5%), jobless(52.3%), had no religion(49.5%), no antenatal(74.5%), and postnatal education on self and infant care(55.9%). A large proportion of primiparae intended to feed breast milk(49.5%) but in fact only 7.2% fed breast milk while in the hospital. Many subjects perceived that they had reasonable self confidence about self care(46.8%), and infant care(36%). 2. The level of nursing needs of overall nursing care was relatively high(Mn 3.98) but the level of satisfaction was of average level(Mn 3.09). Therefore, difference between the level of nursing needs and satisfaction was significant(p=0.0001). 3. The nursing needs by category of nursing care the highest need was on the education of infant care(4.29), the lowest was on physical care(3.80). The level of satisfaction was higher on environmental care(3.40) and physical care(3.32). But the category that showed the lowest satisfaction was education of infant care(2.67). Hence, difference of categories between the level of nursing needs and satisfaction was significant(p=0.0001). 4. Among items of physical care, observation of primiparas' conditions(4.21), accurate medication and treatment(4.18), care of breast engorgement(4.07) and control of postpartal hemorrage(4.01) showed high nursing needs. On the other hand, only the level of satisfaction was higher on accurate medication and treatment(3.82). The rest of items revealed only average level of satisfactions. Difference of items between the level of nursing needs and satisfaction was significant(p=0.0001) except items of dietary care. 5. Among items of psychological care, 8 items of nursing needs were high(3.72-4.29), expecially detailed explanation on which mothers want to know(4.29), treatment and nursing care they receive(4.23), kind and faithful care(4.22), early contacts with their baby(4.20), and adequate draping during the care and treatment(4.18). Among items of psychological care higher satisfactions were shown on items of kind and faithful care(3.80), personal treatment(3.70), and detailed explanation to mothers, but the least satisfied items was early contact with baby(2.13). Difference between the level of nursing needs and satisfaction was significant(p=0.0001). 6. Among items of environmental care, the highest level of need and satisfaction was on the items of neat bedding and pajamas(3.54). The difference was significant (p=0.0001). 7. Among the items of educational needs on self care, all of 22 items revealed higher educational needs(3.50-4.33) but the levels of satisfaction varied with a range of 2.63-3.42. Among the items the satisfactions were high on items of breast care including massages(3.42), perineal care(3.36) and expression of breast milk(3.32). Less satisfied items were drugs not be taken by breast milk feeder(2.63), maintenance of breast figure(2.76) and postpartum exercise(2.80) and so on. The difference was significant(p=0.0001). maintain 8. Among the items of educational needs on infant care, 19 items revealed higher educational needs(3.28-4.54). And the highest need were on the 3 items of normal growth and development of infant, safety and emergency care, symptoms of sick(4.45) and the meaning of crying of the baby(4.52). The level of satisfaction among items of education of infant care ranged from 2.47 to 3.16. Most satisfied items were buriping(3.16), bathing(3.11) and diapering(3.09). The items of which the mother's needs were high revealed the lowest satisfaction level. The difference was significant (p=0.0001). 9. Relationship between nursing needs and levels of satisfaction among primiparae of different characteristics were as follows : 1) Nursing needs of physical and psychological areas were significantly different among different age levels but no relationship was found on other categories regardless of the level of satisfaction. 2) With regard to different levels of education, some relationship was found in nursing needs of psychological area(p=0.007), educational needs on infant care(p=0.04) and environmental care(p=0.01). Also, the difference of satisfaction level was significant. 3) Working mothers had higher nursing needs and were more satisfied on items of physical care(p=0.05), education on self care and infant care. Difference were significant between nursing needs and level of satisfaction. 4) With regards to different religion a moderate relation was found between nursing needs of environmental care infant care education but no relationship was found on levels of satisfaction. 5) With regards to antenatal education, the mothers who have had no antenatal education revealed higher nursing needs on physical care but those who had antenatal education were more satisfied with education on self care and infant care. The difference was significant. (p=0.0001). 6) With regards to postpartum education, the mothers who have had some sort of postpartum education revealed higher nursing needs on physical and self care. And they were more satisfied with nursing of every category except infant care than mothers who had not any postpartum education. Differences was significant between the nursing needs and levels of satisfaction.(p=0.0001). 7) With regards to breast feeding experience during the hospitalization, those who had no experience of breast feeding revealed higher nursing needs on physical care in contrast to breast feeders, who had higher educational needs on infant care. And breast feeder were more satisfied with all categories. Differences was significant(p=0.0001). 8) With regards to perception of self confidence on self care and infant care, no relationship was found on nursing needs and level of satisfaction in every category of nursing.

  • RFID(Radio Frequency Identification)시스템은 하나의 RFDI리더, 다수의 RFID태그 장치들로 이루어진 비접촉방식의 근거리 무선 인식 기술이다. RFID태그는 자체적인 연산 수행이 가능한 능동형 태그와 이에 비해 성능은 떨어지지만 저렴한 가격으로 물류 유통에 적합한 수동형 태그로 나눌 수 있다. 데이터 처리 장치는 리더와 연결되어 리더가 전송받은 정보를 처리한다. RFID 시스템은 무선주파수를 이용해 다수의 태그를 빠른 시간에 인식할 수 있다. RFID시스템은 유통, 물류, 운송, 물품관리, 출입 통제, 금융 등 다양한 분야에서 응용되고 있다. 하지만 RFID시스템을 더욱 확산시키기 위해서는 가격, 크기, 전력소모, 보안 등 해결할 문제가 많다. 그 문제들 중에서 본 논문에서는 다수의 수동형 태그를 인식할 때 발생하는 충돌 문제를 해결하기 위한 알고리즘을 제안한다. RFID 시스템에서 다수의 태그를 인식하기 위한 충돌 방지 기법에는 확률적인 방식과 결정적인 방식 그리고 이를 혼합한 하이브리드 방식이 있다. 본 논문에서는 우선 기존에 있던 확률적 방식의 충돌방지기법인 알로하 기반 프로토콜과 결정적 방식의 충돌방지기법인 트리 기반 프로토콜에 대해 소개한다. 알로하 기반 프로토콜은 시간을 슬롯 단위로 나누고 태그들이 각자 임의로 슬롯을 선택하여 자신의 ID를 전송하는 방식이다. 하지만 알로하 기반 프로토콜은 태그가 슬롯을 선택하는 것이 확률적이기 때문에 모든 태그를 인식하는 것을 보장하지 못한다. 반면, 트리 기반의 프로토콜은 리더의 전송 범위 내에 있는 모든 태그를 인식하는 것을 보장한다. 트리 기반의 프로토콜은 리더가 태그에게 질의 하면 태그가 리더에게 응답하는 방식으로 태그를 인식한다. 리더가 질의 할 때, 두 개 이상의 태그가 응답 한다면 충돌이라고 한다. 충돌이 발생하면 리더는 새로운 질의를 만들어 태그에게 전송한다. 즉, 충돌이 자주 발생하면 새로운 질의를 자주 생성해야하기 때문에 속도가 저하된다. 그렇기 때문에 다수의 태그를 빠르게 인식하기 위해서는 충돌을 줄일 수 있는 효율적인 알고리즘이 필요하다. 모든 RFID태그는 96비트의 EPC(Electronic Product Code)의 태그ID를 가진다. 이렇게 제작된 다수의 태그들은 회사 또는 제조업체에 따라 동일한 프리픽스를 가진 유사한 태그ID를 가지게 된다. 이 경우 쿼리 트리 프로토콜을 이용하여 다수의 태그를 인식 하는 경우 충돌이 자주 일어나게 된다. 그 결과 질의-응답 수는 증가하고 유휴 노드가 발생하여 식별 효율 및 속도에 큰 영향을 미치게 된다. 이 문제를 해결하기 위해 충돌 트리 프로토콜과 M-ary 쿼리 트리 프로토콜이 제안되었다. 하지만 충돌 트리 프로토콜은 쿼리 트리 프로토콜과 마찬가지로 한번에 1비트씩 밖에 인식을 못한다는 단점이 있다. 그리고 유사한 태그ID들이 다수 존재할 경우, M-ary 쿼리 트리 프로토콜을 이용해 인식 하면, 불필요한 질의-응답이 증가한다. 본 논문에서는 이러한 문제를 해결하고자 M-ary 쿼리 트리 프로토콜의 매핑 함수를 이용한 m-비트 인식, 맨체스터 코딩을 이용한 태그 ID의 충돌정보, M-ary 쿼리 트리의 깊이를 하나 감소시킬 수 있는 예측 기법을 이용하여 성능을 향상시킨 적응형 M-ary 쿼리트리 프로토콜을 제안한다. 본 논문에서는 기존의 트리기반의 프로토콜과 제안하는 기법을 동일한 조건으로 실험하여 비교 분석 하였다. 그 결과 제안하는 기법은 식별시간, 식별효율 등에서 다른 기법들보다 성능이 우수하다.

  • The research conducted here focuses on the effect of factors that affect the behavior of UCC (User Created Content) website users, other than user's rational recognition of how useful a UCC website can be. Most discussions in the existing literature on information systems have focused on users' evaluation how a UCC website can help to attain the users' own goals. However, there are other factors and this research pays attention to an individual's 'personality,' which is stable and biological in nature. Specifically, I have noted here that 'extroversion' and 'neuroticism,' the two common personality factors presented in Eysenck's most representative 'EPQ Model' and 'Big Five Model,' are the two personality factors that affect a site's 'usefulness,' by this I mean how useful does the user consider the website and its content. How useful a site is considered by the user is the other factor that has been regarded as the antecedent factor that influences the adoption of information systems in the existing MIS (Management Information System) research. Secondly, as using or creating a UCC website does not guarantee the user's or the creator's extrinsic motivation, unlike when using the information system within an organization, there is a greater likelihood that the increase in user's activities in relation to a UCC website is motivated by emotional factors rather than rational factors. Thus, I have decided to include the relationship between an individual's personality and what they find pleasurable in the research model. Thirdly, when based on the S-O-R Paradigm of Mehrabian and Russell, the two cognitive factors and emotional factors are finally affected by stimulus, and thus these factors ultimately have an effect on an individual's respondent behavior. Therefore, this research has presented an assumption that the recognition of how useful the site and content is and what emotional pleasure it provides will finally affect the behavior of the UCC website users. Finally, the relationship between the recognition of how useful a site is and how pleasurable it is to useand UCC usage may differ depending on certain situational conditions. In other words, the relationship between the three factors may vary according to how much users are involved in the creation of the website content. Creation thus emerges as the keyword of UCC. I analyzed the above relationships through the moderating variable of the user's involvement in the creation of the site. The research result shows the following: When it comes to the relationship between an individual's personality and what they find pleasurable it is extroverted users who have a greater likelihood to feel pleasure when using a UCC website, as was expected in this research. This in turn leads to a more active usage of the UCC web site because a person who is an extrovert likes to spend time on activities with other people, is sensitive to new experiences and stimuli and thus actively responds to these. An extroverted person accepts new UCC activities as part of his/her social life, rather than getting away from this new UCC environment. This is represented by the term 'Foxonomy' where the users meet a variety of users from all over the world and contact new types of content created by these users. However, neuroticism creates the opposite situation to that created by extroversion. The representative symptoms of neuroticism are instability, stress, and tension. These dispositions are more closely related to stress caused by a new environment rather than this creatingcuriosity or pleasure. Thus, neurotic persons have an uneasy feeling and will eventually avoid the situation where their own or others' daily lives are frequently exposed to the open web environment, this eventually makes them have a negative attitude towards the web environment. When it comes to an individual's personality and how useful site is, the two personality factors of extroversion and neuroticism both have a positive relationship with the recognition of how useful the site and its content is. The positive, curious, and social dispositions of extroverted persons tend to make them consider the future usefulness and possibilities of a new type of information system, or website, based on their positive attitude, which has a significant influence on the recognition of how useful these UCC sites are. Neuroticism also favorably affects how useful a UCC website can be through a different mechanism from that of extroversion. As the neurotic persons tend to feel uneasy and have much doubt about a new type of information system, they actively explore its usefulness in order to relieve their uncomfortable feelings. In other words, neurotic persons seek out how useful a site can be in order to secure their own stable feelings. Meanwhile, extroverted persons explore how useful a site can be because of their positive attitude and curiosity. As a lot of MIS research has revealed that the recognition of how useful a site can be and how pleasurable it can be to use have been proven to have a significant effect on UCC activity. However, the relationship between these factors reveals different aspects based on the user's involvement in creation. This factor of creationgauges the interest of users in the creation of UCC contents. Involvement is a variable that shows the level of an individual's mental effort in creating UCC contents. When a user is highly involved in the creation process and makes an enormous effort to create UCC content (classed a part of a high-involvement group), their own pleasure and recognition of how useful the site is have a significantly higher effect on the future usage of the UCC contents, more significantly than the users who sit back and just retrieve the UCC content created by others. The cognitive and emotional response of those in the low-involvement group is unlikely to last long,even if they recognize the contents of a UCC website is pleasurable and useful to them. However, the high-involvement group tends to participate in the creation and the usage of UCC more favorably, connecting the experience with their own goals. In this respect, this research presents an answer to the question; why so many people are participating in the usage of UCC, the representative form of the Web 2.0 that has drastically involved more and more people in the creation of UCC, even if they cannot gain any monetary or social compensation. Neither information system nor a website can succeed unless it secures a certain level of user base. Moreover, it cannot be further developed when the reasons, or problems, for people's participation are not suitably explored, even if it has a certain user base. Thus, what is significant in this research is that it has studied users' respondent behavior based on an individual's innate personality, emotion, and cognitive interaction, unlike the existing research that has focused on 'compensation' to explain users' participation with the UCC website. There are also limitations in this research. Firstly, I divided an individual's personality into extroversion and neuroticism; however, there are many other personal factors such as neuro-psychiatricism, which also needs to be analyzed for its influence on UCC activities. Secondly, as a UCC website comes in many types such as multimedia, Wikis, and podcasting, these types need to be included as a sub-category of the UCC websites and their relationship with personality, emotion, cognition, and behavior also needs to be analyzed.
