  • 본 연구의 목적은 서울시 남산 신갈나무림을 대상으로 과거 조사자료와의 비교·분석을 통해 생태적 특성을 밝히고, 현황 진단 및 생태계 변화 예측을 위한 기초자료를 축적하는데 있다. 연구대상지는 2006년 7월 서울시 생태·경관보전지역으로 지정된 '남산 북사면 신갈나무림'이다. 연구내용은 토양환경 변화(1986~2016) 분석, 현존식생 변화(1978~2016) 분석, 식물군집구조 변화(1994~2016) 분석이다. 식물군집구조 고정조사구는 1994년과 2000년에 설정한 총 8개 고정조사구(400~1,200m2)를 대상으로 하였으며, 분석항목은 상대우점치, 종수 및 개체수, Shannon의 종다양도이다. 남산 토양환경은 산성 토양(pH 4.40)으로 치환성양이온 용량이 낮아 수목 생육에 부정적 영향을 미칠 것으로 예측되었다. 남산의 신갈나무림은 주로 북사면 일대에 분포하며, 현존식생 면적은 49.4%(1978년) → 80.7%(1986년) → 82.4%(2000년) → 88.3%(2005년) → 70.3%(2016년)로 변화하였으며, 2016년에는 2005년과 비교해 세력이 18% 감소하였다. 이러한 변화는 교목층 신갈나무의 생장에 의해 세력이 증가하였다가 2012년 참나무시들음병 확산에 따른 벌채 및 훈증 관리로 그 세력이 크게 감소되었기 때문이다. 식물군집구조 변화 내용은 대부분 참나무시들음병으로 교목층 신갈나무가 훼손되었고, 차대를 형성할 수 있는 잠재식생이 나타나고 있지 않았다. 아교목층은 도시환경 적응 수종인 때죽나무, 팥배나무 등의 세력이 유지 또는 증가하였다. 관목층은 개방된 상층 수관에 의해 종수 및 개체수가 크게 증가하여 군집별 Shannon의 종다양도도 증가하였다. 남산 신갈나무림은 대기오염 및 산성비 등 도시환경의 영향, 참나무시들음병에 의한 신갈나무 단순림의 한계, 외래종의 유입 등 다양한 생태계 변화가 나타나고 있어 지속적인 모니터링을 통한 관리방안 수립이 필요하다.

  • 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.

  • The purpose of the study is to identify the lived experience of mothers who have children with cerebral palsy in order to understand their agony. Moreover, the result of study was to find some nursing intervention for disabled children and their mothers. For this purpose, ten mothers who are willing to cooperate with this research were selected at random from those who have children with the cerebral palsy, currently using the municipal facilities for the handicapped with cerebral malfunction. Data collection was done from October 4, 1994 th December 31, 1994. The data were collected by asking the mothers mentioned above with some unstructured open-ended questions, recorded on the tapes with permission by the interviewee in order to prevent missing of the interviewed contents. These collected data have been substantiated and properly analyzed on the basis of phenomenological approach initiated by Colaizzi's method. The results and validity are proved to be credible by means of the individual checking of the interviewed mothers. The results of this study are as follows : 1. When the mother is first informed of the diagnosis of cerebral palsy on her child, she usually misses the crucial timing needed for proper treatment of the child's disorder because she is notified through the doctor's indifference and his apparently inactive, matter-of-fact attitude. At first she suspects the doctor's diagnosis and tries to attribute it to the unknown cause from a certain genetic problem and then she quickly wants to deny the whole situation that her child is really suffering from the cerebral palsy. The reality is too much for her to accept as it is and she would not believe her child is abnormal. Therefore, she even attempts depend on the power of God for its solution. 2. The mother, who goes thorough this kind of uncommon experiences, is totally devoted to the treatment and care of the child and completely ignores her own life and happiness. At the same time, she feels sorry for her other normal children she believes having not enough care and concern. Also, she feels sorry for the sick child when the child's brothers or sisters show special concern for the patient out of sympathy. It is sorry and not satisfied for her that the child is growing with abnormality and neighbor other around have inappropriate attitudes. Likewise, she is discontent with her husband's lack of concern about the child's treatment. She believes that the health care system in this society isn't fulfilling its due purpose. In the state of her utmost distress and anxiety, she always feels the need of competent consultants, and is angry about that her child is treated as an abnormal being, she is trying to hide the child from other people and to make him or her disappear, if possible. Although she doesn't have harmonious relation with her husband, she id happy when he shows his affection for the child and she feels relieved and thankful when the relatives don't mention about the child's condition Since the child's overall status of health is continuously in unstable conditions, requiring her all-time readiness for an emergency, she feels guilty of her child's illness toward the fEmily members as if it was her own fault to have borne such an abnormal child and she feels responsible for the child morally and financially if necessary Because her life is centered on taking care of the child, she cannot afford to enjoy her own life and happiness. She is a lonely mother, fatigued, with no proper relationship with other people around her. With this sense of guilt and responsibility as a mother of an unusual disease, she has no choice but to grieve her destiny from which she is not allowed to escape. 3. Nevertheless, the mother with the child suffering from the cerebral palsy does not easily give up the hope of getting her child cured and she believes that in the long run, though slower than hoped, her abnormal son or daughter will be eventually cured to become a normal sibling someday. This kind of hope is sustained by the mother's strong faith coming from observing the progress of other similar children getting better. Sometimes she is encouraged to have this faith by other mothers who share the same painful experiences, believing that her child will improve even more rapidly than others with the same palsy. Full of hope, she painstakingly waits for the child's healing. Moreover, she plans to have another child. she thinks that the patient child's brothers and sisters only can truly understand and look after the patients. However, when she notices that the progress of other children under the treatment does not look so hopeful, she is distressed by the thoughts that her child may never get well. Too, she is worried that the patient's brother or sister will be born as the same invalid with the cerebral disease. She is discouraged to have another baby as much as she is encouraged to. She is also troubled by the thought that in case she has another baby, she will have to be forced. to neglect the patient child, especially when she does have an extra hand or some reliable person to help her with taking care of the patient.

  • After the investigation on, and the analysis of, the educational system for medical technicians and the present educational situation for medical technologies in this country, the following conclusions were drawn. 1. As of March 1983 the current academic system for education in medical technologies included the regular 4-year college courses and those of the 2-year professional junior college courses. But except in the cases on clinical pathology and physical therapy, there were no college-level departments. Particularly, no educational institutions, at whatever level, had a department for working therapies. 2. The total number of credits needed for graduation from a department of medical technologies was 150 points at a regular 4-year college and 85 to 96 points at a 2-year professional college. The obligatory minimum number of credits for a student at a professional college was set at 80 points and above. 3. As for the number of the educational institutions for medical technologies in this country, there were one regular college and 14 professional colleges, a total of 15 institutions. As many as 14 colleges had departments of clinical pathology, 12 had departments of Radiotechnology, 11 had departments of physical therapy, 12 had departments of dental technology, and eight had departments of dental hygiene. 4. The total capacity of the professional colleges in admitting new enrollment each year were 1,920 for clinical pathology, 1,552 for radiology, 1,012 for physical therapy, 1,334 for dental technologies, 828 for dental hygiene, an aggregate of 6,646 for all of the professional college departments. 5. The total number of graduates from the 12 professional colleges by department during the period of 1965-83 were 7,595 for clindical pathology, 4,768 for radiology, 2,821 for physical therapy, 3,000 for dental technologies, and 1,787 for dental hygiene, totalling 19,971 for all departments in the professional colleges. 6. In the state examination for licensed medical technicians, 12,446 have passed from among the total of 26,609 participants, representing a 45% passing ratio. By departments the ratios showed 44% for clinical pathology, 39.7% for radiology, 51.2% for physical therapy, 42.5% for dental technology, 72.5% for dental hygiene and 73.1% for working therapy. 7. As for the degree of satisfaction shown by the people in this field, 52.2 percent of the teaching staffs who responed to the questionaires said they were satisfied with their present profession, while the great majority of medical technicians(66%) replied that they were indifferent to the problem. 8. The degree of satisfaction shown by the students on their enrollment in this particular academic field was generally in the framework of indifference(43.7%), but mere students(36.5%) were satisfied with their choice than those were not satisfied(14.4%) 9. As for the student's opinions on the lectures and practicing hours, a good many students replied that, among such courses as general science and humanities courses the basic medical course, the major course and practicing hours, the hours provided for the general courses(47.1%) and practicing(47.6%) were insufficient. 10. When asked about the contents of their major courses, comparatively few students (23.6%) replied that the courses were too difficult, while a convincing majority(58.5%) said they were neither difficult nor easy. As for the appropriateness of the number of the present teaching staffs, a great majority(71.0%) of the students replied that the level of the teaching personnel in each particular field was insufficient. 11. Among the students who responded to the poll, good part of them(49.5%) wanted mandatory clinical practicing hours, and the the majority of them(64.6%) held the view that the experimental and practicing facilities of their schools were insufficient. 12. On the necessity of the attached hospitals, 71.1% of the teaching staffs and 58.0% of the medical technicians had the opinion that this kind of facility was indispensable. 13. As for the qualifications for applicants to the state examination in the licensing system for medical technicians, 52.2% of the teacher's and 36% of the medical technicians replied that the present system granting the qualifications according to the apprenticeship period should be abolished. 14. On the necessity of improving the present system for education in medical technologies, an overwhelming majority(94.4% of the :caching staffs, 92.0% of the medical technicians and 91.9% of students) of these polled replied that the present system should be changed for the better. 15. On the method of changes for the present educational system, a great majority(89.4% of the teaching staffs, 80.4% of the medical technicians and 90.1% of the students) said that the system must be changed so that it fits into the reality of the present day. 16. As for the present 2-year program for the professional colleges, 61.6% of the teachers, 72.0% of the medical technicians and 38.8% of the students expressed the hope that the academic period would be extended to four regular years, hemming a full-fledged collegelevels program. 17. On the life-long eductional system for medical technicians, there was a considerable number of people who expressed the hope that an open university system(38.9% of the teaching staffs, 36.0% of the medical technicians) and a graduate school system would be set up. 18. As for the future prospects for medical technicians as professionals, the optimists ana pessimists were almost equally divided, and 41.1% of the teaching staffs 36.0% of. the technicians and 50.5% of the students expressed an intermediate position on this issue.

  • 경상북도에 소재한 3개 종합병원 영상의학과의 MDCT 검사 중 두부, 복부, 흉부 각 10건씩 30건을 대상으로 CTDIl, DLP, Slice 수, DLP/Slice 수를 조사하여 병원 간 프로토콜의 차이로 인한 MDCT의 피폭선량의 차이를 분석하였고, CT검사의 가장 많은 검사건수를 차지하고 프로토콜이 비교적 단순한 두부 CT를 Helical Scan과 Normal Scan으로 2회 실시하여 영상의 화질, CTDI, DLP, 안구의 피폭선량, 갑상선의 피폭선량의 차이를 분석하였다. 두부CT에서 조사대상 병원의 3분의 2에서 CTDI 참조준위(IAEA 50mGy, 우리나라 60mGy)를 초과하지 않은 A병원에 비하여 유의하게 높았다(p<0.001). DLP에서 조사병원의 3분의 1은 참조준위 IAEA 1,050mGy.cm, 우리나라 1,000mGy.cm의 권고량 보다 높았고, 3분의 2가 우리나라의 권고량을 초과하고 있었다. 참조준위를 초과하지 않은 A병원에 비하여 유의하게 높았다(p<0.001). Abdomen CT에서도 3분의 1은 CTDI 참조준위 IAEA 25mGy, 우리나라 20mGy보다 높은 119mGy를 보였고, DLP에서는 모든 조사대상 병원이 우리나라 권고량 700mGy.cm보다 높았다. 조사대상 병원 중 모든 검사에서 높은 선량을 보인 C병원은 MPR, 3D 검사의 비중이 높아 낮은 pitch, 높은 관전류 검사로 인한 피폭선량이 높았다. Scan 방법에 따른 피폭선량의 차이를 분석하고자 동일환자의 두부CT를 Normal scan과 Helical scan으로 각각 실시하여 분석한 결과 CTDI 및 DLP에서 Helical CT가 Normal scan에 비해 63.4%, 93.7% 높은 선량을 보였다(p<0.05, p<0.01). 그러나 갑상선의 피폭선량은 Normal scan이 87.26% 높았다(p<0.01). Helical CT의 선속은 종심부와 변연부의 모양이 종의 형태를 취하고 있어 두부CT에서 갑상선은 중심선속에서 벗어난 적은 선량으로 피폭된다. 또한 Helical scan시 Gantry 각을 수직으로 사용하였고, Normal scan시에는 Orbitomeatal line에 평행으로 정렬된 Gantry 각을 사용하여 Helical scan에서 갑상선은 피폭선량이 감소하였다. 그러나 본 연구에서 사용된 프로토콜은 식약청의 표준준위에 비해 높은 피폭선량을 보여 식약청의 권고량을 지키기 위해서는 낮은 관전류 높은 Pitch의 사용이 요구되었다. 이번 연구에서 Normal scan과 Helical scan에 따른 화질의 차이는 없는 것으로 분석되어 특별한 경우가 아니면 Normal scan의 표준화된 프로토콜을 사용하고 갑상선의 보호장구를 사용하는 것이 필요하였다. 이번 연구는 일지역의 CT검사 중 일부를 조사하여 분석하였으므로 CT검사의 전체를 평가하는데 무리가 있었다. 그러나 경우에 따라 환자피폭선량의 가이드 권고량을 초과하고 있음을 알 수 있었고, 병원 간의 피폭선량 편차도 있음을 확인 할 수 있었다. 이것을 개선하기 위하여 영상의학과 의사 및 방사선사는 CT 방사선량을 줄이는 최적화된 프로토콜로 CT검사를 시행해야 하고, 환자의 알권리를 위하여 피폭선량은 공개되어야 한다. 그러나 아직 많은 의사들과 방사선사는 이에 대한 인식이 부족하므로 개선을 위하여 CT선량 저감화의 교육프로그램, CT검사에 따른 피폭선량의 공개, 병원의 서비스평가 및 병원인증제 평가항목에 CT검사 피폭선량관리 및 공개항목을 추가 등의 관련기관의 노력과 의료종사자가 CT검사에서 행위의 최적화를 실현하는 최선의 프로토콜을 사용하는 노력이 필요하였다.

  • The US supports the Information and Communication (IC) industry as a strategic one to wield a complete power over the World Market. However, several other countries are also eager to have the support for the IC industry because the industry produces a high added value and has a significant effect on other industries. Korea is not an exception. Korea recently succeeded in the commercialization of CDMA for the first time in the world, after the successful development of TDX. Hence, it is highly likely to get tracked by the US. Although the IC industry is a specific sector of IT, there is a concern that there might be a trade friction between the US and Korea due to a possible competition. It will be very important to prepare a solution in advance so that Korea could prevent the friction and at the same time increase its share domestically and globally. It will be our important task to solve the problem with the minimum cost if the conflict arises unfortunately in the IT area. The parties that have a strong influence on the US trade policy are the think tank group and the IT-related interest group. Therefore, it would be important to have a close relationship with them. We found some implications by analyzing the case of Japan, which has experienced trade frictions with the US over the long period of time in the high tech industry. In order to get rid of those conflicts with the US, the Japanese did the following things : (1) The Japanese government developed supporting theories and also resorted to international support so that the world could support the Japanese theories. (2) Through continual dialogue with the US business people, the Japanese business people sought after solutions to share profits among the Japanese and the US both in the domestic and in the worldwide markets. They focused on lobbying activities to influence the US public opinion to support the Japanese. The specific implementation plan was first to open culture lobby toward opinion leaders who were leaders about the US opinion. The institution, Japan Society, were formed to deliver a high quality lobbying activities. The second plan is economic lobby. They have established Japanese Economic Institute at Washington. They provide information about Japan regularly or irregularly to the US government, research institution, universities, etc., that are interested in Japan. The main objective behind these activities though is to advertise the validity of Japanese policy. Japanese top executives, practical interest groups on international trade, are trying to justify their position by direct contact with the US policy makers. The third one is political lobby. Japan is very careful about this political lobby. It is doing its best not to give impression that Japan is trying to shape the US policy making. It is collecting a vast amount of information to make a correct judgment on situation. It is not tilted toward one political party or the other, and is rather developing a long-term network of people who understand and support the Japanese policy. The following implications were drawn from the experience of Japan. First, the Korean government should develop a long-term plan and execute it to improve the Korean image perceived by American people. Second, the Korean government should begin public relation activities toward the US elite group. It is inevitable to make an effort to advertise Korea to this elite group because this group leads public opinion in the USA. Third, the Korean government needs the development of a relevant policy to elevate the positive atmosphere for advertising toward the US. For example, we need information about to whom and how to about lobbying activities, personnel network who immediately respond to wrong articles about Korea in the US press, and lastly the most recent data bank of Korean support group inside the USA. Fourth, the Korean government should create an atmosphere to facilitate the advertising toward the US. Examples include provision of incentives in tax on the expenses for the advertising toward the US and provision of rewards to those who significantly contribute to the advertising activities. Fifth, the Korean government should perform the role of a bridge between Korean and the US business people. Sixth, the government should promptly analyze the policy of IT industry, a strategic area, and timely distribute information to industries in Korea. Since the Korean government is the only institution that has formal contact with the US government, it is highly likely to provide information of a high quality. The followings are some implications for business institutions. First, Korean business organization should carefully analyze and observe the business policy and managerial conditions of US companies. It is very important to do so because all the trade frictions arise at the business level. Second, it is also very important that the top management of Korean firms contact the opinion leaders of the US. Third, it is critically needed that Korean business people sent to the USA do their part for PR activities. Fourth, it is very important to advertise to American employees in Korean companies. If we cannot convince our American employees, it would be a lot harder to convince regular American. Therefore, it is very important to make the American employees the support group for Korean ways. Fifth, it should try to get much information as early as possible about the US firms policy in the IT area. It should give an enormous effort on early collection of information because by doing so it has more time to respond. Sixth, it should research on the PR cases of foreign enterprise or non-American companies inside the USA. The research needs to identify the success factors and the failure factors. Finally, the business firm will get more valuable information if it analyzes and responds to, according to each medium.

  • 본 논문의 목적은 스티브 팩스톤의 작품에서 드러난 일상적 움직임 특성을 분석하는 것이다. 예술작품은 오랜 시간동안 고급문화로서 높은 계층의 사람들에게만 향유되는 특별한 대상으로서 인식되어왔다. 일상과 예술의 간극은 크게 존재해왔고 때문에 예술작품에서 일상적인 요소의 출현은 사회적 변화를 수반한 대중의 인식전환을 의미한다. 예술과 일상의 경계가 불분명해지는 시대로서 포스트모더니즘의 시대는 2차 세계대전 이후의 전후사회 그리고 후기 자본주의사회로서 급변하는 정세를 배경으로 가진다. 이 시기의 변화는 학자들에게 일상과 관련한 개념들을 학문적으로 접근하게 하는 계기가 되어졌으며 예술가들에게는 총체성을 거부하는 다원주의 성향의 포스트모더니즘의 시대정신으로서 영향을 미쳤다. 같은 시기 현대 무용역시 포스트모던댄스로의 전환기를 맞이하게 되었다. 2차 세계대전 이후 현대무용은 그 한계점에 도달한 것으로 평가되기 시작했으며 이러한 상황에서 저드슨 댄스 씨어터를 비롯한 무용가들을 필두로 포스트모던댄스는 전개되었다. 저드슨 댄스의 설립자 중 한 명인 스티브 팩스톤은 머스 커닝햄의 무용수로 활동을 하며 움직임이 생성되는 과정과 계급적인 사회구조를 지닌 무용단의 생태에 문제의식을 가지게 되었다. 이러한 그의 사고는 일상적인 동작을 그대로 작품에 실현하는 시도로서 초기 작품 활동에 드러난다. 일상적인 동작의 활용이 포스트모던댄스의 공공연한 특징으로 간주되어지고 있음에도 이에 주목한 선행연구가 드물다는 점, 그리고 팩스톤 관련 연구들은 접촉즉흥에 관련한 것으로 편향되어 있다는 것에서 본 연구는 시작되었다. 때문에 접촉즉흥 기법에 치중하기 이전 일상적인 동작의 사용으로서 작품활동을 시작한 것에 주목하여 그 연결선상으로서 이후의 작품들을 살펴볼 것이다. 본 연구는 팩스톤의 작품인 ,,를 분석하고 이를 토대로 일상적 특성을 도출하였다. 일상에 관련한 개념을 고찰하고 포스트모던댄스의 무용사적 흐름을 파악하기 위하여 관련 저서와 학술 논문, 무용기사 및 평론을 참고하여 진행하였다. 팩스톤은 무용적 정제를 거치지 않은 일상에서의 동작을 작품에 그대로 차용하였으며 그 시작으로 보행동작은 비무용수인 공연자들의 보행으로서 일상적인 움직임에 미적 의의를 부여하였다. 팩스톤이 심취한 접촉즉흥의 움직임 역시 자연스러운 에너지의 흐름을 중시하는 것으로 일상적인 측면을 지니며 이후의 작품인 에서도 그는 이완된 신체로 평범한 동작들을 선보였다. 작품에 등장한 일상적 움직임의 특성은 반복되는 삶에서의 실천과 특별하지 않은 평범한 것이라는 기준으로서 분석되었다. 그의 작품에 내재된 일상적 움직임은 한 시대의 무용장르의 변화를 비롯하여 전통적으로 유지되어온 무용예술 작품에 관한 인식의 전환을 대변하는 것이다. 파격적인 시도와 실험성으로 점철된 그의 활동은 현대무용이 지녔던 한계점을 극복하기 위한 노력으로서 보다 높게 평가 되어져야 할 것이다.
