  • 현재 정보통신기술의 비약적인 발전은 물리적인 거래 패러다임을 전자방식으로 확대시키는 극적인 변화를 주도하고 있다. 주지하는 바와 같이, 금융서비스는 거래당사자간 대부분의 금융거래를 지원하고 있다. 그러므로 전자거래의 확대는 금융서비스를 제공하는 모든 금융기관들에도 영향을 미치고 있다. 이에 따라 모든 금융기관들은 정쟁에서 살아남기 위해 e-Finance 시스템을 도입하여 인터넷금융 서비스를 제공하고 있다. 본 연구의 목적은 이용자측면에서 인터넷을 이용한 e-Finance의 이용 실태와 확산요인을 분석함으로써 e-Finance 고객서비스의 질적인 향상과 신속한 확산 그리고 올바른 전략 수립에 기여하는 것이다. 본 연구는 기존문헌 검토와 요인 및 신뢰도 분석을 통해 e-Finance 자체에 대한 지각된 효율성과 지각된 신뢰 및 안전성, e-Finance 시스템에 대한 신뢰도, 기술적 요소, 고객서비스 품질 그리고 개인특성에 있어 혁신성향 등 6가지를 확산요인으로 채택한다. 로지스틱 회귀분석을 이용한 가설 검증 결과에 따르면, e-Finance시스템에 있어서 기술적 요소와 고객서비스 품질 그리고 개인 특성에 있어 혁신성향은 e-Finance의 확산여부에 각각 유의수준 0.05와 0.01%에서 통계적으로 정의 영향을 갖는 것으로 나타났다. 그렇지만 e-Finance 자체에 대한 지각된 효율성과 지각된 신뢰 및 안전성은 이의 확산여부에 별다른 영향을 미치지 않는 것으로 나타났다. 또한 e-Finance 시스템과 관련하여 시스템의 신뢰도는 통계적으로 이의 확산에 유의적이지 못하였다. 본 연구는 추후 이용자 측면에서 e-Finance 확산요인에 관해 실증적 연구를 하는데 기본적인 자료로서 이용될 수 있고, 이에 대한 기업이나 정부의 정책 수립 또는 구현과 금융기관의 고객서비스 품질정도 결정에 이용될 수 있다. 그러나 본 연구는 만족요인과 이의 e-Finance에 대한 영향을 다루지 못했다는 점과 국내 이용자만을 대상으로 했다는 점 그리고 다중희귀분석을 실시하지 못했다는 점 등 몇 가지 한계를 갖는다.

  • When Korean family planning services began as a part of the National Policy in 1962, the annual population growth was 3.0%. This growth rate has been decreased to 2.0% during last ten year period. And it seems imperative that all hospitals, as well as related organizations, should participate in family planning in order to contribute to achieving the National goal of 1.5% population growth by 1976, the end of the Third Five Year Economic Development Plan. Nurses should be considered the most important human resources in charge of the core of family planning services in any setting. For the family planning services in the general hospital setting, nurses as a core members contribute much as change agent, motivators, counsellors, educators etc. A nurse can work with patients and their relatives when she is equipped with relevant knowledge and skills. Fur the more family planning cannot be ignored even in hospital setting where more comprehensive nursing care is needed Thus, the general objective of this study is to provide baseline data for better programming of In-service education in family planning so that effective hospital family planning nursing services can be made a part of comprehensive nursing care contributing to the national population program and human welfare. In order to meet the general objective, this study has the following specific objectives : 1. To find out the general characteristics of the clinical nurses working in Y Hospital 2. To evaluate their attitudes and practices of family planning 3. To assess their knowledge, attitudes and practices of population and family planning as professional nurses. 4. To examine and compare data collecting methods for the planning of an In-service Educational Program 5. To explore the contents to be included in this In-service Education Program. The study population randomly selected one hundred nurses working in Y Hospital A cross-sectional survey with questionnaires developed for this study was chosen for the study method. To collect reliable data, the questionnaires were distributed to and answered by the study population in a controlled situation. X²test and t-test was employed in analyzing the data. The findings of this study are as follows: 1. Y Hospital nurses had a lower ideal number of children (X=2.02) and showed no strong preference for male children, and 74% of them expressed the desire to use permanent methods of birth control 2. of this thirty Y Hospital nurses who were married 66.7% stated they were already practicing contraceptive methods. Most of them preferred male methods of contraception. 3. According to objective evaluation about knowledge of various aspects of population and family planning, respondents from collegiate programs significantly knew better the subjects on the average than did respondents from diploma programs of nursing. 4. There was a marked difference in the results of self-evaluation and objective evaluation in their family planning knowledge. It was found that the self-evaluation family planning knowledge seemed to be unreliable. Accordingly, the objective test methods appeared to be more reliable in the evaluation of knowledge levels. 5. The subject areas needed to be included in In-service education for the Hospital family planning services in Y Hospital are 1) rhythm methods, 2) tubal-legation, 3) family planning effects of contraceptives, 4) population growth, 5) demographic traction, 6) population structure and 7) infant mortality facts. In addition, 1) various oral contraceptives, 2) basal temperature method, 3) laparoscopic female sterilization, 4) interfering factors of family planning, 5) anatomy and physiology of the female reproductive organs were additional areas to be taught to respondents from 3-year diploma schools of nursing. Demographic transition was one subject area in which the four-year graduates need further study. 6. Population problems guidance and counselling in family planning instruction in the theory and practice of contraceptives should be included in future In-service Education Programs in order to provide more effective hospital Family Planning Services, stated 77.0% of the respondents.

  • 본 연구는 경관담당 공무원을 대상으로 경관제도에 대한 인식을 조사하여 향후 경관관련 제도 개선에 기초적인 자료를 제공할 목적으로 진행되었다. 구체적으로는 다양한 경관제도에 대한 중요도 및 성취도를 분석하고, 경관계획, 경관사업, 경관협정, 경관심의 및 경관위원회, 경관조례 및 경관행정 등에 대한 경관담당 공무원의 인식을 조사하였다. 주요 연구결과를 요약하면 다음과 같다. 1. 경관법과 경관제도에 대해서는 전반적으로 관심이 높았으며, 경관법이나 경관헌장에 관한 효용성에 대해서도 긍정적인 인식을 가지고 있었다. 중요도-성취도 분석결과, 경관계획과 경관정책기본계획은 집중적으로 개선이 필요한 것으로 나타났다. 2. 경관계획은 주로 경관심의나 민원 요청에 대응하는 용도로 가장 활용이 많이 되고 있었으나, 거의 보지 않는다는 응답도 10.8% 정도로 적지 않아, 경관계획 내용을 현실화하고, 실행력을 높이기 위한 노력이 시급한 것으로 보인다. 경관계획 수립기간으로는 18개월 미만이 적정하다는 인식이 많았으나, 이에 대해서는 인식 개선이 필요한 것으로 판단한다. 3. 경관사업이나 경관협정의 개선을 위해서는 예산확보, 전문가, 추진조직 등이 우선적으로 개선해야 할 항목인 것으로 나타났다. 4. 경관심의와 경관위원회를 보완하기 위해서는 주로 경관심의 위원들의 심의에 관한 전문성을 높이는 것이 시급한 것으로 조사되었다. 5. 경관조례 및 경관행정에 관한 보완사항으로는 인원보강과 같은 행정적 지원이 필요한 것으로 나타났으며, 담당자로서 주관적 판단을 하는 것에 상황도 큰 부담인 것으로 조사되었다. 경관 교육을 위해 모인 공무원만을 대상으로 하여 연구결과에 긍정적 편향은 있을 수 있으나, 경관관련 제도에 관한 전반적인 경향을 살펴보는 데 도움이 될 것으로 판단한다. 향후 경관 제도를 보다 현실적으로 개선하는데 도움이 되길 기대한다.

  • 목적: 최근 출생 후 조기 퇴원과 모유수유 증가로 인해 신생아 고빌리루빈혈증에 의한 재입원 비율이 증가하고 있다. 신생아 고빌리루빈혈증은 적절한 시기에 치료하지 않으면 빌리루빈 뇌증을 유발하여 치명적인 신경학적 후유증을 남길 수 있어 적절한 치료와 함께 조기 예방의 중요성이 부각되고 있다. 이에 저자는 우리나라 신생아의 특발성 비용혈성 고빌리루빈혈증의 임상 경과와 위험 인자, 뇌 MRI 결과를 조사함으로써 황달의 역학 조사와 치료 방침 설정의 기초 자료를 얻고자 본 연구를 시행하였다. 방법: 2006년 1월부터 2009년 9월까지 고빌리루빈혈증으로 진단받고 경북대학교병원 신생아 집중치료실에 입원한 환아 중 재태연령이 35주 이상, 총혈청 빌리루빈이 20 mg/dL 이상이면 서 용혈성 질환이 없으면서 감염, 대사 질환등 황달의 원인이 없는 79명의 환아를 대상으로 의무 기록을 후향적으로 조사하였다. 결과: 평균 재태주령은 $38^{+3}{\pm}1^{+4}$주였고 내원 당시 나이는 8.8$\pm$4.0일이었다. 내원 당시 체중은 3,105$\pm$479 g으로 출생 체중 3,174$\pm$406 g과 비교하여 평균 2.8$\pm$6.4% 감소하였다. 모유수유, 두혈종, 경막하출혈 및 ABO 부적합증과 같은 위험인자가 있는 환아와 위험인자가 없는 환아를 비교하였으며 최고 총혈청빌리루빈, 광선요법의 시행 기간 및 반응 정도에서 유의한 차이를 보이지 않았다. 출생 체중과 입원 당시 체중을 비교하여 체중이 증가한 군과 감소한 군의 비교에서는 재태주령, 내원 당시 연령과 최고 혈청 빌리루빈치가 유의한 차이를 보였다. 뇌 MRI를 시행한 39명의 환아 중 21명은 T1 강조 영상에서 창백핵의 음영이 피각 및 인접한 피질척수로의 음영과 비교하여 증가된 소견을 보였다. 43명의 환아가 ABR을 시행하였는데 5명의 환아에서 이상 소견이 보였다. 결론: 우리나라에서 발생하는 특발성 비용혈성 고빌리루빈혈증은 수유량 부족이 원인이 될 수 있으므로 수유방법에 대한 충분한 교육과 퇴원 후 정기적인 추적 관찰이 필요하다. 본 연구는 많은 대상군을 포함하지 않아 더 많은 대상군과 대조군의 비교분석이 필요하고 향후 장기적인 추적 관찰을 통해서 만성 빌리루빈 뇌증에 대한 연구도 필요할 것으로 생각된다.

  • At present in the medical care, the study and effort for producing health service to consider efficiency, effectiveness, and quality are urgently called for because of the difficulty in the keen competition according to the inter- nationalization and opening, the operation in the medical institution service testing system, the change in the medical policy of KDRGs, and the lack of the health care cost increasing rate. As an alternative, the case management for the new management system is introduced in the U.S., and the Critical Pathway that is the method designing the contents of activity and its result has been developed and applied in order to anticipate and manage the patient-outcome for the realization of the cost-effective case-management. Thus, this study intended to analyze the effectiveness to obtain by developing the Critical Pathway presented as the method to improve the quality-betterment and cost effectiveness through the continuous and consistent patient management for the hysterectomy patient and applying it to the real practice. As a study method, this author formed a conceptual framework through considering five Critical Pathway used in the current U.S. and three Critical Pathway presented in the literature to develop the Critical Pathway for the hysterectomy patient, and made out the preliminary Critical Pathway through reviewing the old chart. This author made the verified the validity of the expert group about the developed Critical Pathway, and to confirm the possibility of practice application, completed and settled the final Critical Pathway after using the Critical Pathway to the hysterectomy patient from March 1st to 15th, 1997. Finally, to analyze the application-effect of the developed Critical Pathway, this author offered health care service applying the Critical Pathway to the hysterectomy patient from April 15th to August 31th, 1997. The guide for the Critical Pathway was carried out in advance by outpatient setting nurse for outpatient setting visit before the operation, and after hospitalization the primary nurse monitored the execution degree on the every duty. After discharge this author surveyed the complication through phone visiting, and one month after discharge surveyed the patient's reaction about the offered service when outpatient setting visit and analyzed the result. The source for health care cost was obtained by the statistics about the hospital charge which was offered by the General Business Department. The results were as follows. 1. It was decided that the vertical line of the Critical Pathway was made up of eight items such as monitoring/assessment, treatment, line/drains, activity, medication, lab test, diet, patient teaching, and the horizontal line of the Critical Pathway was made up of from hospitalization to discharge. 2. After the analysis of service contents through reviewing the old chart, it was decided that the horizontal line of the preliminary Critical Pathway was made up of from hopitalization to fourth postoperative day, and the vertical line of it was divided into eight items which were the contents to occur with the time frame of the horizontal line. 3. After the verifying the validity of the expert group about the preliminary Critical Pathway, the horizontal line was amended from hopitalization to third postoperative day, and taking their consensus, some contents of the horizontal line was amended and deleted. 4. From March 1st to 15th, 1997, to confirm the clinical suitability, this author offered eight hysterectomy patients the medical service through the Critical Pathway. The result was that three of them could be discharged at the expected discharge day, and the others later than that day. Supplementing the preliminary Critical Pathway through analyzing the cause of that delay- case, this author developed the final Critical Pathway. 5. There were no significant differences between the experimental and the control group in the incidence of complication(P > 0.05). 6. The 92.4% of experimental group was satisfied with the Critical Pathway service. 7. The length of hospital stay of the experimental group offered with the Critical Pathway service was 4.6 days and there was a significant difference that it was 1.3 days shorter than that of the control group(t=-29.514, P=0.000). 8. There wsa a significant difference that the mean medical charge per one patient of the experimental group offered the Critical Pathway service was cheaper \124,150 than that of the control group(t=-9.826, P=0.000). 9. The result that the author assumed and analyzed hospital income with the rate of turning bed was assumed that the increase of hospital income was \63,245,072 for that study, and the income increase was expected with \68,704,864 for a year. The result that this author applied the Critical Pathway to the hysterectomy patient have no differences in the incidence of complication, high satisfaction with that service, and the length of hospital stay decreased in the experimental group, and the mean hospital charge per one patient decreased, but hospital income increased. Suggestions for further study and nursing practice are as follows. 1. The study to apply the Critical Pathway for a year, verify the validity, and measure the effect repeatedly is needed. 2. To apply and manage the Critical Pathway effectively, the study to computerize it is needed. 3. The study to develop hospital-based Critical Pathway about other diseases or procedure, and measure the effect is needed.

  • This study reports on a comparison between the Korean diffusion of agricultural innovation or extension service and the cooperative extension service in the United States of America. It focuses on relevant differences between the two systems and provides recommendation for improvement of the Korean system to insure success in important areas related to the diffusion of agricultural innovations. After a comparative study on diffusion of innovations it is clear that: in order to have a productive agriculture that makes effective and efficient use of natural resources and helps achieve sustainability goals, a mechanism that delivers knowledge to agricultural communities must be established and maintained. This mechanism is clearly an agricultural extension service that is cooperatively funded by federal, state and local governments and that insures participation of constituents in the process of establishing priorities and evaluating achievements. The success of US agriculture, the most productive in the world, is to a large degree to the Cooperative Extension Service. Based on the results of this study and the differences of the United States and Korea, the following recommendations should be emphasized for more effective communication for agricultural innovation and rural development in Korea: 1) In order to insure that extension educators are high caliber professional individuals, it is important to establish a system that nationally recognizes these individuals as such, and that provides a professional development path. 2) The results of the decision of transfer of extension educators to local governments has not yielded positive outcomes, especially in terms of professional status. It is clearly demonstrable that valuable professionals are leaving the service, that local governments do not have the will and resources to implement a successful extension program. 3) Because of the critical importance of diffusing innovations to agricultural producers in order to insure and quality and steady food supply, it is of critical importance that these issues be addressed before the extension service is further deteriorated. Given the cement situation, it is clear that the extension service should become nationally supported again in cooperation with local and state governments and that extension professionals be given appropriate rank at the national level, commesurate with their peers in research and teaching. 4) The common current committee practice of lengthy reporting and short discussion needs to be changed to one that results in char, brief and substantive action oriented goals. Joint participation by researchers, extension educators and farmers should be encouraged in planning, implementation and evaluation of communication for agricultural innovations. Roles and functions of committees for institutional cooperation, and or agricultural extension committees should be enlarged. 5) Extension educators should be encouraged to adopt new communication technologies to improve their diffusion of innovations methods. Agricultural institutions and organizations should be encouraged to adopt farmer-first and or client-oriented approach in agricultural extension and diffusion of agricultural technologies. The number, complexity and rapid change of information in agricultural extension require the development of a computer based information and report system to support agricultural extension. 6) To facilitate and expand the further development of communication for agricultural innovation and rural development, agricultural communication programs in universities especially in colleges of agriculture and life sciences. 7) To strengthening the sense of national and social responsibility communication for agricultural innovation and rural development among students in agricultural colleges and universities through participation in learning activities by proactive recruitment. 8) To establish and reinforce a policy that insures participation in communication for agricultural innovation and regal development activities. 9) To improve further development of communication for agricultural innovation and rural development in Korea, more research activities should be encouraged.

  • Smartphone and its applications (i.e. apps) are increasingly penetrating consumer markets. According to a recent report from Korea Communications Commission, nearly 50% of mobile subscribers in South Korea are smartphone users that accounts for over 25 million people. In particular, the importance of smartphone has risen as a geospatially-aware device that provides various location-based services (LBS) equipped with GPS capability. The popular LBS include map and navigation, traffic and transportation updates, shopping and coupon services, and location-sensitive social network services. Overall, the emerging location-based smartphone apps (LBA) offer significant value by providing greater connectivity, personalization, and information and entertainment in a location-specific context. Conversely, the rapid growth of LBA and their benefits have been accompanied by concerns over the collection and dissemination of individual users' personal information through ongoing tracking of their location, identity, preferences, and social behaviors. The majority of LBA users tend to agree and consent to the LBA provider's terms and privacy policy on use of location data to get the immediate services. This tendency further increases the potential risks of unprotected exposure of personal information and serious invasion and breaches of individual privacy. To address the complex issues surrounding LBA particularly from the user's behavioral perspective, this study applied the privacy calculus model (PCM) to explore the factors that influence the adoption of LBA. According to PCM, consumers are engaged in a dynamic adjustment process in which privacy risks are weighted against benefits of information disclosure. Consistent with the principal notion of PCM, we investigated how individual users make a risk-benefit assessment under which personalized service and locatability act as benefit-side factors and information privacy risks act as a risk-side factor accompanying LBA adoption. In addition, we consider the moderating role of trust on the service providers in the prohibiting effects of privacy risks on user intention to adopt LBA. Further we include perceived ease of use and usefulness as additional constructs to examine whether the technology acceptance model (TAM) can be applied in the context of LBA adoption. The research model with ten (10) hypotheses was tested using data gathered from 98 respondents through a quasi-experimental survey method. During the survey, each participant was asked to navigate the website where the experimental simulation of a LBA allows the participant to purchase time-and-location sensitive discounted tickets for nearby stores. Structural equations modeling using partial least square validated the instrument and the proposed model. The results showed that six (6) out of ten (10) hypotheses were supported. On the subject of the core PCM, H2 (locatability ${\rightarrow}$ intention to use LBA) and H3 (privacy risks ${\rightarrow}$ intention to use LBA) were supported, while H1 (personalization ${\rightarrow}$ intention to use LBA) was not supported. Further, we could not any interaction effects (personalization X privacy risks, H4 & locatability X privacy risks, H5) on the intention to use LBA. In terms of privacy risks and trust, as mentioned above we found the significant negative influence from privacy risks on intention to use (H3), but positive influence from trust, which supported H6 (trust ${\rightarrow}$ intention to use LBA). The moderating effect of trust on the negative relationship between privacy risks and intention to use LBA was tested and confirmed by supporting H7 (privacy risks X trust ${\rightarrow}$ intention to use LBA). The two hypotheses regarding to the TAM, including H8 (perceived ease of use ${\rightarrow}$ perceived usefulness) and H9 (perceived ease of use ${\rightarrow}$ intention to use LBA) were supported; however, H10 (perceived effectiveness ${\rightarrow}$ intention to use LBA) was not supported. Results of this study offer the following key findings and implications. First the application of PCM was found to be a good analysis framework in the context of LBA adoption. Many of the hypotheses in the model were confirmed and the high value of $R^2$ (i.,e., 51%) indicated a good fit of the model. In particular, locatability and privacy risks are found to be the appropriate PCM-based antecedent variables. Second, the existence of moderating effect of trust on service provider suggests that the same marginal change in the level of privacy risks may differentially influence the intention to use LBA. That is, while the privacy risks increasingly become important social issues and will negatively influence the intention to use LBA, it is critical for LBA providers to build consumer trust and confidence to successfully mitigate this negative impact. Lastly, we could not find sufficient evidence that the intention to use LBA is influenced by perceived usefulness, which has been very well supported in most previous TAM research. This may suggest that more future research should examine the validity of applying TAM and further extend or modify it in the context of LBA or other similar smartphone apps.

  • 본 연구에서는 나물용 팥으로 새롭게 개발된 팥 신품종 연두채의 나물로의 이용 가능성을 평가하고 그 추출물에 대한 항산화성분 및 항산화활성을 측정하였다. 발아시간에 따른 싹 및 뿌리의 길이와 나물 수율을 고려해 볼 때 연두채는 120~144시간 발아시키는 것이 바람직할 것으로 생각된다. 발아시간에 따라 수분은 유의적으로 증가하였고 단백질은 유의적으로 약간 증가하였으나 큰 차이를 보이지 않았다. 연두채의 칼슘, 마그네슘 함량은 유의적으로 증가하는 경향을 보였고 칼륨, 나트륨, 알루미늄 함량은 유의적인 차이를 보이지 않았다. 발아시간에 따른 에탄올 추출물의 총 폴리페놀, 플라보노이드 및 탄닌 등 항산화성분의 함량은 발아시간에 따라 유의적인 차이를 보였다. 충주팥, 연두채, 다현녹두 원료곡의 총 폴리페놀 함량은 각각 1.96, 2.68 및 2.02 mg/g이었고 충주팥과 연두채는 144시간(각각 3.33 및 3.47 mg/g)에 높은 함량을 나타내었다. 원료곡의 총 플라보노이드 함량은 발아시간이 증가함에 따라 충주팥과 연두채가 대체적으로 감소하는 경향을 보였다. 원료곡의 총 탄닌 함량은 발아시간이 증가함에 따라 대체적으로 증가하는 경향을 보였고 충주팥은 120시간(0.96 mg/g), 연두채는 144시간(0.85 mg/g), 다현녹두는 120시간(1.62 mg/g)에 높은 함량을 보였다. 원료곡의 DPPH radical 소거활성은 발아시간이 증가함에 따라 충주팥과 연두채는 대체적으로 감소하고 다현녹두는 증가하였다. ABTS radical 소거활성은 각각 4.57, 6.51 및 2.82 mg TE/g이었고 충주팥과 연두채는 발아 초반에 감소하다가 각각 120 및 72시간 이후 증가하였다. 이상의 결과 연두채 싹나물은 다현녹두 나물에 비해 항산화성분 및 활성은 약간 낮으나 수율이 높고 탄닌 등 쓴맛 성분이 낮아 싹나물로의 이용성이 기대된다.
