  • 본 연구는 생명공학과 관련 기술의 활용에 대한 일반 국민들의 인식과 태도, 그리고 그 인식과 태도에 영향을 미치는 심리적 요인들에 대해 탐색해 보려 하였다. 대학생과 일반 성인집단을 대상으로 생명공학과 기술에 대한 자유연상 반응 및 질문지 응답을 통해 얻어진 결과를 분석하였다. 생명공학 연구 및 기술활용과 관련한 한국 성인들의 인식 내용은 '인간의 존엄성 손상' '인체에 유해한 부작용' '도덕적 혼란' '상업적 악용' 등의 불확실성이나 부작용에 대한 염려와 '질병치료' '수명연장' '식량문제 해결' 등의 긍정적 기대를 중심으로 표상되어 있었다. 생명공학 및 그 기술 활용과 관련한 대학생들의 관심과 인지도는 비교적 높았고, 관련 정보를 얻는 주된 출처는 'TV'와 '신문' 및 '인터넷' 등이었으며, 생명공학이 사회에 미치는 영향의 판단에 대해 신뢰하는 집단으로 '과학자'와 '시민단체'를 들고 있었다. 생명공학 기술의 적용에는 호의적인 태도를 보이지만, '유전자변형 콩으로 만든 두부'의 부작용을 염려하고 먹지 않겠다는 반응이 많았다. 또 개인 유전정보를 사회적이나 공적으로 이용하거나 관리하는 데 대해서는 매우 부정적인 태도를 보이고 있었다. '급진성'과 '행동활성화 체계의 민감성' 및 '신뢰감'과 '적개심' 등의 심리적 속성들이 생명공학 및 그 기술의 활용과 관련한 '관심과 인지도' 및 '기술의 활용의도'와 의미 있게 관련되어 있었다. 또 생명공학에 대한 인지도가 높다고 해서 호의적인 태도가 높은 것은 아니었다. 끝으로 본 연구에서 얻어진 결과의 의미와 추후 연구에 대해 논의하였다.

  • 목적 : 구인두암으로 방사선치료를 받은 환자들을 대상으로 후향적 분석을 시행하여 생존율, 치료 실패 양상 및 생존율에 미치는 요인 등을 알아보고자 하였다. 방법 : 1985년 3월부터 1993년 6월까지 경북대학교병원 치료방사선과에서 구인두암으로 방사선치료를 시행한 53예의 환자를 대상으로 후향적 분석을 시행하였다. 환자의 연령은 31세에서 73세로 중간값은 54세였으며 남자 47예 여자 6예였다. 조직학적으로 편평세포암종이 42예, 미분화암종 이 10예, 선양 낭성암종이 1예였다. 병기별 분포는 I기 2예, II기 12예, III기 12예, IV기 27예이었다. T1 7예, T2 28예, t3 10예, T4 7예, T병기가 불명확한 경우가 1예이었고, N0 17예, Nl 13예, N2 21예, N3 2예였다. 원발병소는 편도 36예, 설기저부 12예, 그리고 연구개 5예였다. 방사선 단독치료가 25예, 유도화학요법 및 방사선치료 병용요법이 28예였다. 유도화학요법은 CF (cisplatln, 5-fluorouracil) 또는 CVB (cisplatin, vincristine, bleomycin) 약제로 1-3회 시행하였다 방사선치료는 6MV X선 및 8-10MeV 전자선을 이용하였고 방사선 치료선량은 일일 180-200 cGy씩 총 4500-7740 cGy로 중간값은 7100 cGy였다. 환자의 추적기간은 4개월에서 99개월로 중간추적기간이 21개월이었다. 결과 : 방사선치료 후 37예 ($69.8\%$)에서 완전관해를 보였고 16예 ($30.2\%$) 에서 부분관해를 보였다. 전체 환자에서 2년생존율은 $47\%$, 3년생존율은 $42\%$였고 중앙생존기간은 23개월이었다. 치료에 대한 반응 (p=0.004) 및 전체병기가 (p=0.02) 통계적으로 의미있게 생존율에 영향을 미치는 것으로 나타났다. 2년 무병생존율은 $45.5\%$였고 T 병기 (p=0.03), N 병기 (p=0.04) 및 전체병기가 (p=0.04) 의미있게 무병생존을에 영향을 미치는 것으로 나타났다. 환자의 나이, 성별, 조직학적 소견, 원발병소, 방사선량 및 화학요법과의 병합치료는 무병생존율에 영향을 주지 않았다. 방사선치료 후 완전관해를 보인 36예 중 추적조사가 가능했던 32예에서의 치료 실패양상은 국소재발이 8예, 원격전이가 4예로 주된 치료 실패 원인은 국소재발이었다. 결론 : 본 연구에서는 N 병기, 7 병기 및 전체병기가 무병 생존율에 영향을 미치는 인자로 나타났으며, 국소재발이 주된 실패 요인이 되고 있어 국소완치를 위한 노력이 절실히 요구된다. 현재까지 구인두암의 치료는 방사선 단독치료가 가장 효과적인 치료방법으로 여겨지며 화학요법은 좀더 많은 비교 대조군 연구를 통해서만 역할을 평가할 수 있을 것으로 사료된다.

  • This project was a service-cum-research effort with a quasi-experimental study design to examine the health benefits of an integrated Family Planning (FP)/Maternal & Child health (MCH) Service approach that provides crucial factors missing in the present on-going programs. The specific objectives were: 1) To test the effectiveness of trained nurse/midwives (MW) assigned as change agents in the Health Sub-Center (HSC) to bring about the changes in the eight FP/MCH indicators, namely; (i)FP/MCH contacts between field workers and their clients (ii) the use of effective FP methods, (iii) the inter-birth interval and/or open interval, (iv) prenatal care by medically qualified personnel, (v) medically supervised deliveries, (vi) the rate of induced abortion, (vii) maternal and infant morbidity, and (viii) preinatal & infant mortality. 2) To measure the integrative linkage (contacts) between MW & HSC workers and between HSC and clients. 3) To examine the organizational or administrative factors influencing integrative linkage between health workers. Study design; The above objectives called for quasi-experimental design setting up a study and control area with and without a midwife. An active intervention program (FP/MCH minimum 'package' program) was conducted for a 2 year period from June 1982-July 1984 in Seosan County and 'before and after' surveys were conducted to measure the change. Service input; This study was undertaken by the Soonchunhyang University in collaboration with WHO. After a baseline survery in 1981, trained nurses/midwives were introduced into two health sub-centers in a rural setting (Seosan county) for a 2 year period from 1982 to 1984. A major service input was the establishment of midwifery services in the existing health delivery system with emphasis on nurse/midwife's role as the link between health workers (nurse aids) and village health workers, and the referral of risk patients to the private physician (OBGY specialist). An evaluation survey was made in August 1984 to assess the effectiveness of this alternative integrated approach in the study areas in comparison with the control area which had normal government services. Method of evaluation; a. In this study, the primary objective was first to examine to what extent the FP/MCH package program brought about changes in the pre-determined eight indicators (outcome and impact measures) and the following relationship was first analyzed; b. Nevertheless, this project did not automatically accept the assumption that if two or more activities were integrated, the results would automatically be better than a non-integrated or categorical program. There is a need to assess the 'integration process' itself within the package program. The process of integration was measured in terms of interactive linkages, or the quantity & quality of contacts between workers & clients and among workers. Intergrative linkages were hypothesized to be influenced by organizational factors at the HSC clinic level including HSC goals, sltrurture, authority, leadership style, resources, and personal characteristics of HSC staff. The extent or degree of integration, as measured by the intensity of integrative linkages, was in turn presumed to influence programme performance. Thus as indicated diagrammatically below, organizational factors constituted the independent variables, integration as the intervening variable and programme performance with respect to family planning and health services as the dependent variable: Concerning organizational factors, however, due to the limited number of HSCs (2 in the study area and 3 in the control area), they were studied by participatory observation of an anthropologist who was independent of the project. In this observation, we examined whether the assumed integration process actually occurred or not. If not, what were the constraints in producing an effective integration process. Summary of Findings; A) Program effects and impact 1. Effects on FP use: During this 2 year action period, FP acceptance increased from 58% in 1981 to 78% in 1984 in both the study and control areas. This increase in both areas was mainly due to the new family planning campaign driven by the Government for the same study period. Therefore, there was no increment of FP acceptance rate due to additional input of MW to the on-going FP program. But in the study area, quality aspects of FP were somewhat improved, having a better continuation rate of IUDs & pills and more use of effective Contraceptive methods in comparison with the control area. 2. Effects of use of MCH services: Between the study and control areas, however, there was a significant difference in maternal and child health care. For example, the coverage of prenatal care was increased from 53% for 1981 birth cohort to 75% for 1984 birth cohort in the study area. In the control area, the same increased from 41% (1981) to 65% (1984). It is noteworthy that almost two thirds of the recent birth cohort received prenatal care even in the control area, indicating that there is a growing demand of MCH care as the size of family norm becomes smaller 3. There has been a substantive increase in delivery care by medical professions in the study area, with an annual increase rate of 10% due to midwives input in the study areas. The project had about two times greater effect on postnatal care (68% vs. 33%) at delivery care(45.2% vs. 26.1%). 4. The study area had better reproductive efficiency (wanted pregancies with FP practice & healthy live births survived by one year old) than the control area, especially among women under 30 (14.1% vs. 9.6%). The proportion of women who preferred the 1st trimester for their first prenatal care rose significantly in the study area as compared to the control area (24% vs 13%). B) Effects on Interactive Linkage 1. This project made a contribution in making several useful steps in the direction of service integration, namely; i) The health workers have become familiar with procedures on how to work together with each other (especially with a midwife) in carrying out their work in FP/MCH and, ii) The health workers have gotten a feeling of the usefulness of family health records (statistical integration) in identifying targets in their own work and their usefulness in caring for family health. 2. On the other hand, because of a lack of required organizational factors, complete linkage was not obtained as the project intended. i) In regards to the government health worker's activities in terms of home visiting there was not much difference between the study & control areas though the MW did more home visiting than Government health workers. ii) In assessing the service performance of MW & health workers, the midwives balanced their workload between 40% FP, 40% MCH & 20% other activities (mainly immunization). However, $85{\sim}90%$ of the services provided by the health workers were other than FP/MCH, mainly for immunizations such as the encephalitis campaign. In the control area, a similar pattern was observed. Over 75% of their service was other than FP/MCH. Therefore, the pattern shows the health workers are a long way from becoming multipurpose workers even though the government is pushing in this direction. 3. Villagers were much more likely to visit the health sub-center clinic in the study area than in the control area (58% vs.31%) and for more combined care (45% vs.23%). C) Organization factors (admistrative integrative issues) 1. When MW (new workers with higher qualification) were introduced to HSC, it was noted that there were conflicts between the existing HSC workers (Nurse aids with less qualification than MW) and the MW for the beginning period of the project. The cause of the conflict was studied by an anthropologist and it was pointed out that these functional integration problems stemmed from the structural inadequacies of the health subcenter organization as indicated below; i) There is still no general consensus about the objectives and goals of the project between the project staff and the existing health workers. ii) There is no formal linkage between the responsibility of each member's job in the health sub-center. iii) There is still little chance for midwives to play a catalytic role or to establish communicative networks between workers in order to link various knowledge and skills to provide better FP/MCH services in the health sub-center. 2. Based on the above findings the project recommended to the County Chief (who has power to control the administrative staff and the technical staff in his county) the following ; i) In order to solve the conflicts between the individual roles and functions in performing health care activities, there must be goals agreed upon by both. ii) The health sub·center must function as an autonomous organization to undertake the integration health project. In order to do that, it is necessary to support administrative considerations, and to establish a communication system for supervision and to control of the health sub-centers. iii) The administrative organization, tentatively, must be organized to bind the health worker's midwive's and director's jobs by an organic relationship in order to achieve the integrative system under the leadership of health sub-center director. After submitting this observation report, there has been better understanding from frequent meetings & communication between HW/MW in FP/MCH work as the program developed. Lessons learned from the Seosan Project (on issues of FP/MCH integration in Korea); 1) A majority or about 80% of the couples are now practicing FP. As indicated by the study, there is a growing demand from clients for the health system to provide more MCH services than FP in order to maintain the achieved small size of family through FP practice. It is fortunate to see that the government is now formulating a MCH policy for the year 2,000 and revising MCH laws and regulations to emphasize more MCH care for achieving a small size family through family planning practice. 2) Goal consensus in FP/MCH shouBd be made among the health workers It administrators, especially to emphasize the need of care of 'wanted' child. But there is a long way to go to realize the 'real' integration of FP into MCH in Korea, unless there is a structural integration FP/MCH because a categorical FP is still first priority to reduce the rate of population growth for economic reasons but not yet for health/welfare reasons in practice. 3) There should be more financial allocation: (i) a midwife should be made available to help to promote the MCH program and coordinate services, (in) there should be a health sub·center director who can provide leadership training for managing the integrated program. There is a need for 'organizational support', if the decision of integration is made to obtain benefit from both FP & MCH. In other words, costs should be paid equally to both FP/MCH. The integration slogan itself, without the commitment of paying such costs, is powerless to advocate it. 4) Need of management training for middle level health personnel is more acute as the Government has already constructed 90 MCH centers attached to the County Health Center but without adequate manpower, facilities, and guidelines for integrating the work of both FP and MCH. 5) The local government still considers these MCH centers only as delivery centers to take care only of those visiting maternity cases. The MCH center should be a center for the managment of all pregnancies occurring in the community and the promotion of FP with a systematic and effective linkage of resources available in the county such as i.e. Village Health Worker, Community Health Practitioner, Health Sub-center Physicians & Health workers, Doctors and Midwives in MCH center, OBGY Specialists in clinics & hospitals as practiced by the Seosan project at primary health care level.

  • 결제서비스에 대한 기존의 연구는 결제서비스의 채택요인 또는 지속적인 사용에 영향을 미치는 요인 등 행동이론을 중심으로 진행되어 왔다. 이러한 요인들이 미치는 영향에 대한 결과는 결제서비스의 종류에 따라 또는 연구 지역에 따라 상이하게 나타나고 있다. 본 연구는 결제 서비스의 종류나 문화등의 변수에 관계없이 새로운 결제 서비스가 성공할 수 있는 일반적인 요인이 무엇인지에 대한 의문에서 시작하게 되었다. 기존 연구에서 중요한 영향을 미친다고 제시한 채택요인들은 실제 결제사례의 결과에 비추어 보면 기존 연구에서 주장한 바와 일치하지 않는 경우를 볼 수 있다. 이러한 이론과 현실사이의 괴리를 발견하고 새로운 결제서비스가 성공하기 위한 근본적이고 결정적인 요인이 무엇인지에 대해 제시하고 사례연구를 통해 가설을 입증하고자 하는 것이 본 연구의 목적이다. 따라서 본 연구는 새로운 결제서비스가 성공하기 위해서는 기존 결제서비스의 비고객에게 이들이 결제할 수 있는 수단을 제공함으로써 새로운 결제 시장을 창출해야 함을 주장한다. 이를 위해 성공한 결제사례인 신용카드, 휴대폰 소액결제, PayPal, Square을 채택하였으며, 기존 결제서비스의 비고객을 3개의 계층으로 분류하여 분석하였다. 그리고 새로운 결제서비스가 어떠한 계층을 타겟으로 하였으며 이들에게 어떠한 결제수단을 제공하여 새로운 시장을 창출하였는지 제시한다. 사례 분석 결과, 성공 사례 모두 본 연구의 가설을 지지하는 것으로 나타났다. 따라서 새로운 결제서비스는 결국 기존의 결제수단으로 거래를 할 수 없었던 이들이 결제를 할 수 있도록 함으로써 성공할 수 있다는 가설을 입증하였다. 모바일 결제서비스가 아직 대중화되지 못한 원인을 본 가설에 비추어 분석해 보면 보면, 기존의 결제 인프라를 이용할 수 있는 바코드, QR코드 기반의 모바일 결제 서비스뿐만 아니라 NFC, BLE, 음파 등의 새로운 기술이 적용된 모바일 결제 서비스가 출시되는 등 새로운 시도가 계속되고 있다. 또한 모바일 월렛은 사용자들이 소지하고 있는 카드정보를 스마트폰에 저장하여 지갑 없이도 결제가 가능하며, 쿠폰 제공, 적립카드 관리, 신분증을 저장하는 등의 다양한 부가적인 기능을 제공하고 있어 성공할 것이라는 전망이 대두되고 있다. 하지만 이러한 서비스들은 본 연구 관점에서 보자면 기존 결제서비스의 비고객이(기존 결제수단을 이용할 수 없었던 사용자) 거래할 수 있는 새로운 결제 수단을 제공해 주지 못하고 있기 때문에 결국 초기사용자에게만 채택될 뿐 대중화되는데 한계가 있을 것으로 예상된다. 반면, 새로운 모바일 결제서비스의 성공사례 중 하나인 PaybyPhone은 기존 코인주차 결제서비스의 비고객인 현금 미소지 고객에게 스마트폰을 이용한 새로운 결제수단을 제공함으로써 새로운 주차 결제 시장을 창출하였으며 현재 미국뿐만 아니라 유럽시장까지 진출하는 등 급성장하고 있다. 결론적으로, 많은 이해관계자들이 모바일 결제시장을 선점하기 위해 다양한 형태의 모바일 결제 서비스를 출시하고 있지만 캐즘을 뛰어넘어 주류 시장에 성공적으로 정착할 수 있느냐는 결국 기존 결제서비스의 비고객군에게 그들이 필요로 하는 새로운 결제수단을 제공하는지의 여부에 달려있다고 볼 수 있다. 따라서 모바일 결제 서비스의 기획자나 매니저들은 서비스 기획 시 기존 결제서비스의 비고객군은 누구인가? 그들은 어떠한 결제수단을 원하는가?를 먼저 고려해야 한다. 본 연구는 새로운 결제서비스가 성공하는데 미치는 요인에 대한 가설을 검증하기 위해 4개의 성공사례를 선택하였으며 각 사례에 동일한 가설을 검증하는 '반복연구논리'를 적용하였다. 본 가설을 더욱 공고히 하기 위해 사례연구방법론에서 제시하고 있는 경쟁가설을 포함한 후속 사례연구가 진행되어야 할 것이다.

  • Electronic commerce, commonly known as e-commerce or eCommerce, has become a major business trend in these days. The amount of trade conducted electronically has grown extraordinarily by developing the Internet technology. Most electronic commerce has being conducted between businesses to customers; therefore, the researches with respect to e-commerce are to find customer's needs, behaviors through statistical methods. However, the statistical researches, mostly based on a questionnaire, are the static researches, They can tell us the dynamic relationships between initial purchasing and repurchasing. Therefore, this study proposes dynamic research model for analyzing the cause of initial purchasing and repurchasing. This paper is based on the System-Dynamic theory, using the powerful simulation model with some restriction, The restrictions are based on the theory TAM(Technology Acceptance Model), PAM, and TPB(Theory of Planned Behavior). This article investigates not only the customer's purchasing and repurchasing behavior by passing of time but also the interactive effects to one another. This research model has six scenarios and three steps for analyzing customer behaviors. The first step is the research of purchasing situations. The second step is the research of repurchasing situations. Finally, the third step is to study the relationship between initial purchasing and repurchasing. The purpose of six scenarios is to find the customer's purchasing patterns according to the environmental changes. We set six variables in these scenarios by (1) changing the number of products; (2) changing the number of contents in on-line shopping malls; (3) having multimedia files or not in the shopping mall web sites; (4) grading on-line communities; (5) changing the qualities of products; (6) changing the customer's degree of confidence on products. First three variables are applied to study customer's purchasing behavior, and the other variables are applied to repurchasing behavior study. Through the simulation study, this paper presents some inter-relational result about customer purchasing behaviors, For example, Active community actions are not the increasing factor of purchasing but the increasing factor of word of mouth effect, Additionally. The higher products' quality, the more word of mouth effects increase. The number of products and contents on the web sites have same influence on people's buying behaviors. All simulation methods in this paper is not only display the result of each scenario but also find how to affect each other. Hence, electronic commerce firm can make more realistic marketing strategy about consumer behavior through this dynamic simulation research. Moreover, dynamic analysis method can predict the results which help the decision of marketing strategy by using the time-line graph. Consequently, this dynamic simulation analysis could be a useful research model to make firm's competitive advantage. However, this simulation model needs more further study. With respect to reality, this simulation model has some limitations. There are some missing factors which affect customer's buying behaviors in this model. The first missing factor is the customer's degree of recognition of brands. The second factor is the degree of customer satisfaction. The third factor is the power of word of mouth in the specific region. Generally, word of mouth affects significantly on a region's culture, even people's buying behaviors. The last missing factor is the user interface environment in the internet or other on-line shopping tools. In order to get more realistic result, these factors might be essential matters to make better research in the future studies.

  • IT기술의 고속 발전에 따라 사용자들이 기술을 사용하는 방식에 큰 변화가 생기고 있다. 전통적인 서비스 응용과 저효율의 데이터를 처리하는 방식은 사용자의 요구를 만족할 수 없다. 사용자들이 데이터의 중요성을 알게 되었고, 빅 데이터에 관한 처리와 저장기술은 오늘날의 인터넷 회사의 주요 연구방향이 되고 있다. 115 네트워크 디스크는 중국에서 폭넓게 사용되기 시작하였고 각 인터넷 회사들은 클라우드 서비스 시장을 쟁탈하는 싸움에 참여하기 시작하였다. 중국의 클라우드 서비스는 아직도 스토리지 서비스 위주이지만, 이 기능을 바탕으로 확장하는 서비스 내용도 사용자의 인정을 받고 있으며, 사용자들이 이러한 새로운 서비스 방식을 사용하는 것을 시도하고 있다. 그래서 어떻게 하면 사용자들이 지속적으로 클라우드 서비스를 사용 할 것인지에 관한 연구방향이 더욱 필요해 졌다. 하나의 전통적인 정보 시스템에 대해, 학자들은 대개 TAM(Technology acceptance model)모형과 통계학을 결합하여 이 시스템에 대한 사용자들의 태도를 분석하고 검증한다. 하지만 기본적인 TAM모형은 날이 갈수록 방대해지는 시스템의 규모를 만족 할 수 없게 되었다. 따라서 TAM모형에 대한 적당한 확장과 조절이 필요하게 되었다. 본 연구는 중국의 개인용 클라우드 서비스 사용자의 지속적인 사용의도에 영향을 미치는 요인에 관한 실증분석을 목표로 브랜드 영향력, 하드웨어 환경 등 외부 변수를 추가하고, 중국 클라우드 사용자를 대상으로 설문 조사를 진행했으며, 본 논문에서 분석을 통해 수정된 모형에 관한 가설을 검증하였다. 본 연구는 주로 중국의 4개 주요 도시의 210명의 클라우드 서비스 사용자를 대상으로 인터넷 설문 조사를 실행하였다. 설문 데이터를 통해 3개의 외부 변수에 대한 분석을 진행하였고, 이 3개의 외부 변수를 세분화하고 외부요소에 영향을 주는 주요 원인을 찾아냈다. 이를 바탕으로 개인 클라우드 서비스 사용자들이 서비스를 지속적으로 사용 할 수 있는 태도를 강화 할 수 있는 것에 유용한 의견을 제시하였다. 이러한 의견들은 중국사용자들을 대상으로 하는 주요 서비스를 제공 하는 회사에게 향후 서비스 방향을 참고할 수 있는 정보를 제공한다.

  • 다양한 빅데이터 기술이 발전함에 따라, 기업의 전략결정에 있어서 과거에는 의사결정자의 직관이나 경험에 의존하는 경향이 있었다면, 현재는 데이터를 활용한 과학적이고 분석적인 접근이 이루어지고 있다. 이에 많은 기업들이 경영정보시스템 중의 하나인 비즈니스 인텔리전스 (Business Intelligence) 시스템의 예측분석 기능을 활용하고 있다. 하지만, 이러한 시스템이 미래의 경영환경 변화를 예측하고 기업의 의사결정을 돕는 조언자 (Advisor)로서 역할을 한다고 가정할 때, 시스템에서 제공하는 분석결과가 의사결정자에게 도움을 주는 조언 (Advice) 의 역할을 하지 못하는 경우가 많은 실정이다. 따라서, 본 연구에서는 미래예측의 문제에 있어 의사결정자가 시스템의 조언을 따르는데 영향을 미치는 요소들과 영향력에 대해 분석하고, 그 결과를 바탕으로 데이터 기반의 의사결정을 보다 적극적으로 지원하는 시스템 환경을 제시하고자 한다. 좀 더 구체적으로는 예측 과정에 대한 자세한 설명이나 근거 제시가 시스템의 예측결과에 대한 의사결정자의 수용정도에 미치는 영향을 연구하였다. 이를 위하여 193명의 실험자를 대상으로 영화의 개봉 주 매출액을 예측하는 업무를 수행하고, 예측에 대한 설명의 길이와 조언자의 유형(사람과 시스템의 조언 비교)뿐 아니라 의사결정자의 개인 특성이 의사결정자의 조언 수용정도에 미치는 영향을 분석하였다. 시스템에서 제공하는 조언 내용인 예측결과와 설명에 대해 의사결정가가 느끼는 유용성, 신뢰성, 만족도가 조언의 수용에 미치는 영향도 분석하였다. 본 연구는 시스템의 분석결과를 조언으로 보고 조언자와 조언에 관한 의사결정학 분야의 선행연구를 접목시켜 경영정보시스템 연구 분야를 확장하였다는 점에서 연구의 의의가 있고, 실무적으로도 데이터 기반의 의사결정을 보다 적극적으로 지원할 수 있는 시스템 환경을 만들기 위해서 고려해야 할 점들을 제시함으로써 시스템 활용을 위한 정책결정에도 도움을 줄 수 있을 것으로 본다.

  • Asia-Pacific Space Cooperation Organization (APSCO) is the only intergovernmental space cooperation organization in Asia. Since its establishment to date, eight countries have signed the convention and become member states. South Korea participated actively in the preparatory phase of creating the organization, and one conference organized by AP-MCSTA which is the predecessor of APSCO was held in South Korea. However, after the APSCO Convention was opened for signature in 2005 to date, South Korea does not ratify the Convention and become a member. The rapid development of space commercialization and privatization, as well as the fastest growing commercial space market in Asia, provides opportunities for Asian countries to cooperate with each other in relevant space fields. And to participate in the existing cooperation framework (e.g., the APSCO) by the Asian space countries (e.g., South Korea) could be a proper choice. Even if the essential cooperation in particular space fields is challenging, joint space programs among different Asian countries for dealing with the common events can be initiated at the first steps. Since APSCO has learned the successful legal arrangements from ESA, the legal measures established by its Convention are believed to be qualified to ensure the achievement of benefits of different member states. For example, the regulation of the "fair return" principle confirms that the return of interests from the relevant programs is in proportion to the member's investment in the programs. Moreover, the distinguish of basic and optional activities intends to authorize the freedom of the members to choose programs to participate. And for the voting procedure, the acceptance of the "consensus" by the Council is in favor of protecting the member's interest when making decisions. However, political factors that are potential to block the participation of South Korea in APSCO are difficult to be ignored. A recent event is an announcement of deploying THAAD by South Korea, which causes tension between South Korea and China. The cooperation between these two states in space activities will be influenced. A long-standing barrier is that China acts as a non-member of the main international export control mechanism, i.e., the MTCR. The U.S takes this fact as the main reason to prevent South Korea to cooperate with China in developing space programs. Although the political factors that will block the participation of South Korea in APSCO are not easy to removed shortly, legal measures can be taken to reduce the political influence. More specifically, APSCO is recommended to ensure the achievement of commercial interests of different cooperation programs by regulating precisely the implementation of the "fair return" principle. Furthermore, APSCO is also suggested to contribute to managing the common regional events by sharing satellite data. And it is anticipated that these measures can effectively response the requirements of the rapid development of space commercialization and the increasing common needs of Asia, thereby to provide a platform for the further cooperation. In addition, in order to directly reduce the political influence, two legal measures are necessary to be taken: Firstly, to clarify the rights and responsibilities of the host state (i.e., China) as providing assistance, coordination and services to the management of the Organization to release the worries of the other member states that the host state will control the Organization's activities. And secondly, to illustrate that the cooperation in APSCO is for the non-military purpose (a narrow sense of "peaceful purpose") to reduce the political concerns. Regional cooperation in Asia regarding space affairs is considered to be a general trend in the future, so if the participation of South Korea in APSCO can be finally proved to be feasible, there will be an opportunity to discuss the creation of a comprehensive institutionalized framework for space cooperation in Asia.

  • Inspite of the lots of studies on the harmfulness of cigarette smoking to the body published by many researchers since 1950, cigarette smoking people are increasing in number especially, cigarette smoking by young and women causes a serious problem. Examining the physiological motives of youth shows that, impulse which the youth want to immitate the adults, alluring curiousity, and defiant physiology of escaping from the norm of traditional groups which has been banned are cooperated well compoundly. As the period of the youth is the one which they accumulate knowledge and charactor by learning as well as the period of growth mentally, and physically they should be rightly educated about smoking before they addicted to smoking and it is desirable for us to make the youth to understand how harmfully the smoking is to effect to their growth and mental soundness simply not as a social norm which they should not smoke. The main motive of this study on the attitude of smoking by the youth is to give basic materials related on this field. For this study, 647 questionnaires were used as studying material which were able to analyze among 720 questionnaires of 2 classes of each grade of 3 high schools among the high schools of boys, girls and co-educated in Seoul from Oct. 21, 1988 through Oct. 26, 1988. Study Instrument are graded in Likert's 5 point from 40 questions which are 20 questions m affirmations and 20 questions in negations after analyzing the factors on 60 simple sentence questions which the students showed in preliminary studies. And these are systemized to be measured from 1 point which means they think smoking IS very bad to 5points which means they think smoking is really good. In these collected materials, technical statistics of frequency. percentage, average, standard deviation are used for general character and smoking attitude, $X^2-test$ for examinning Independant variables of physical. emotional, ethical and other areas pearson's coefficient of correlation for related direction and degree" and step­regression analysis for the degree of relative contribution of all variables which effect smoking attitude. The results of this study are as follows; 1. The smoking attitude of high school boys and girls showed average of 1.78 in physical area, 2.63 in emotional area, 2.61 in ethical area, 2.29 in other area respectively in a negative attitude generally also the negative attitude are expressed most strongly in physical area. I've can also say by this results that smoking is harmful to their health and further more it can be judged that this proves the youth in the period of preparation be adults have a strong curiousity in the emotional, ethical and other areas. 2. The most influential variables in each field as related factors effecting smoking attitude of the student can be explained from 13.2 in physical area the lowest experienced variables to 25.2 in emotional area the highest of degree of smoking experience. The fact that the more the smoking experienced students are increasing in number the higher tendency which accept the' smoking tells as the importance of health education about the population of latest student's smoking as important variables shown equally in each area. Those of grade, age, numbers of smoking people in house are showed meaningful in pure interrelation. Those related to the acceptance of teacher's smoking, sex, mothors education are shown meaningful in opposite interrelations. This means that the' increasing number' of smoking people in grade age, the number of smoker in family have a affirmative attitude. And people who are not interested in teacher's smoking wants to quit it, and whose mother's education is higher have a negative attitude. 3. The most negatively answered questions of the smoking attitude In physical, emotional, ethical and other areas are as belows; Firstly too much smoking is harmful to our health is 1.12 point. Secondly smoking have a ill-effect on pregnancy and embryo is 1.13 point. Thirdly smoking is harmful· to our health is 1.27 point. Fourthly smoking in crowed area with the people such as In a bus or subway should be prohibited is 1.27point. Fifthly smoking can ruin lungs is 1.31 point. And the most affirmatively answered questions are also as below; Firstly we showed smoke depending on time and place is 3.96 points. Secondly smoking is just habit is 3.83 points. Thirdly smoking people seem to be unable and deplorable is 3.69 point. Fourthly smoking should be prohibited by law is 3.56 points. Fifthly high school student's smoking is immitation of adults is 3.52 points.
