  • In this study, the wet surface heat transfer coefficients and friction factors of PF heat exchangers are presented. Two sample with different fin pitch(1.25mm, 1.5mm) were tested. Tests were conducted in a open loop wind tunnel. The wet surface heat transfer coefficient was reduced following the procedure given in ARI 410-81. Results showed that the heat transfer coefficients of the heat exchanger with 1.5mm fin pitch were approximately the same as those with 1.25mm fin pitch, except at low reynolds number(Re<100), where the heat transfer coefficients of 1.5mm fin pitch were slighly higher than those with 1.25mm fin pitch. The friction factors of the 1.25mm fin pitch, however was 120 % to 160 % higher than those of the 1.5mm fin pitch. The wet surface heat transfer coefficients were lower than those of the dry surface. The wet surface friction factors, however, were higher than those of the dry surface.

  • 이 연구의 목적은 FTA컨설팅의 맥락에서 어떤 설명개념들이 컨설팅지식의 학습촉진 컨설팅전이에 중요한 영향을 미치는지 확인하려는 것이다. 160개 수출기업의 원산지관리자들로부터 자료를 수집하여 다중회귀분석을 실시하였다. 분석결과, 클라이언트의 학습에 대해서는 지식의 모호성(-) 및 복잡성(+), 컨설팅수행능력(+), 컨설팅 설계/전달(+), 자기효능감(+), 정부지원(+)이 유의하며, 컨설팅전이에 대해서는 컨설턴트의 전문지식(+), 컨설팅참여도(+), 전이풍토(+)가 각각 유의한 영향을 미친 것으로 나타났다. 컨설팅 수행능력과 지식의 모호성은 학습에 대하여, 그리고 컨설턴트의 전문지식은 컨설팅전이에 대하여 각각 상대적 영향력이 큰 것으로 나타났다. 이는 컨설팅성공은 클라이언트측 투입요인보다는 컨설턴트의 전문지식과 컨설팅수행능력에 크게 달려 있음을 시사한다. 컨설팅 성공을 위해서는 컨설턴트들은 컨설턴트-클라이언트 간의 공유 인터페이스로서 컨설팅방법론 및 툴의 개발과 효과적인 활용이 중요하다.

  • 본 연구는 전문가 설문기법으로 한국 군사기술의 상용이전에 영향을 미치는 주요한 요인들을 조사 분석하였다. 국방연구개발 투자의 효과로서 필요한 군사과학기술 개발과 더불어 군에서 민간부문으로의 기술이전을 통한 상용기술개발을 촉진하는 역할도 중요하게 여겨지고 있다. 군사선진국들은 국방기술개발에 대한 효과적이고 효율적인 투자의 중요성을 인식하고 자국의 특성을 고려하여 국가수준에서 연구개발투자의 효과를 극대화할 수 있는 최적의 기술이전 메커니즘을 적용하기 위해 노력하고 있다. 기술이전 메커니즘은 국가마다 다양하며 한국에서 효과적이고 효율적인 기술이전을 위한 영향요인은 무엇인지를 알아보는 것이 필요하다. 본 논문은 전문가 면담과 문헌연구를 통하여 고려대상 영향요인 19개를 식별하였으며 이중 11개가 기술이전활동에 유의한 영향을 미치는 것으로 나타났다. 정책적 함의로서 목표 지향적 투자, 기술이전 관련 규정의 검토, 그리고 기술이전 전문가 양성에 대한 필요성을 제기하고 있다.

  • Purpose: To examine factors affecting long-term care hospital patients' intention of transfer to a nursing home. Method: A questionnaire survey was conducted in Aug. 2007 that included 655 patients from 49 long-term care hospitals. The survey aimed to assess the patients' health status, family status, cost and intention of transfer to a nursing home. Institutional characteristics were analyzed from the nationwide database of Health Insurance Review & Assessment Service. The affecting factors were examined by employing chi-square test and logistic regression using SAS 8.2. Result: Of the subjects, 32.4% had intention of transfer to a nursing home. The intention of transfer to a nursing home was affected by moderate or severe pain, living together with the primary carer, high cost uncovered by insurance, and recognition of nursing home. Conclusion; For appropriate service utilization. a higher level of care is needed to satisfy patients at nursing homes and a balanced fee schedule is needed between long term care hospitals and nursing homes. It is desirable to encourage transfer to a nursing home at which nurses support patients and their families by giving information, coordination, and to make efforts to establish a reference system.

  • This study was carried out to establish an effective system for embryo transfer techniques by analyzing several factors affecting in-vivo embryo transfer in Korean cattle Embryos were transferred into a toral of 301 recipients. The results obtained in studies on the factors affecting pregnancy rate after embryo transfer by condition of transfer time were as follows ; 1. The pregnancy rate by the seasons of transferred fresh and frozen embryos were not different, but the pregnancy rate was slightly higher in summer(80.8%). 2. The pregnancy rate by the days of embryo transfer after estrus were not different when fresh embryos were transferred, but the pregnancy rate was highest at 8 days when frozen embryos were transferred(P<0.01, 40.0%). 3. The pregnancy rate at estrus synchronization was remarkably higher with PGF$_2$$\alpha$ treated than natural (P<0.05, 70.4%, 43.4%). 4. The pragnancy rate by the degree of estrus synchronization was best when the estrus was synchronized in both fresh and frozen embryos (83.3% and 29.7%, respectively), but the pregnancy rate was not different among $\pm$2 days. But the pregnancy rate of frozen embryos were slightly higher when the recipients exhibited estrus earlier than donors.

  • An empirical analysis study applied to evaluate the effect of critical factors for technology transfer. The research aims to suggest ways of political support in order to facilitate technological transfer and commercialization of public research institute'technology. Based on previous researches, it is determined that five critical factors which effect on technology commercialization. These critical factors are used to derive the order of priority, attribute of the success, and failure factors. The result of this research emphasized on both roles of technology introduction motivation and type of technology transfer. In order to collect data for this research, it is carried out that survey and field study toward to technology user such as manufacturing companies which have contracted with institute A. This research has a meaning in aspects of verification of previous hypothesis through scientific approach and new findings of a significant factor that motivation determines the success or failure of technology commercialization.

  • Turbulent boundary layer noise is already a significant contributor to sonar self noise. For developing acoustic window of sonar system to reduce self noise, a parametric study of design factors of acoustic window is presented. Distance of sensor array from acoustic window, materials of acoustic window and characteristics of damping layer are studied as design factors to influence in the characteristics of the transfer function of self noise. As the result, these design factors make change the characteristics of transfer function slightly. Among design factors the location of sensor array is most important parameter in the self noise reduction

  • Increasing productivity of knowledge workers is a significant issue in the 21st century referred as knowledge-based society. The core key word is behavior of knowledge transfer among members of an organization. The objective of this study is to investigate a model based on Triandis theory and Social Capital theory. This explored the antecedent factors of knowledge Transfer in ITO(Information Technology Outsourcing) Organization. Data were derived from 42 respondents working IT Cooperation in Seoul, Korea. In this paper, we introduce the research model for the knowledge transfer. In order to validate the proposed research model, social network analysis tool, UCINET, a structural equation modeling tool, SmartPLS, was utilized. The empirical result showed that, all antecedent factors (intention of knowledge sharing, anticipated reciprocal relationships, subjective norm, closeness network centrality) of knowledge transfer behavior were significant. In conclusion, findings and implications were discussed and limitations of the study and future research directions were suggested.

  • A technical approach to design and carry out an experiment to determine the uptake of selected radionuclides in site-specific conditions in Kuwait was developed and successfully executed for developing a radioecological decision support system. The radionuclides from soil-to-plant transfer factors have been obtained for leafy and non-leafy vegetables, and root crops cultivated in Kuwait. Two types of vegetated soils were selected and spiked with high concentrations of three relatively short-lived selected radionuclides (85Sr, 134Cs, and 133Ba). The highest strontium and barium transfer factors were found in the order: leafy vegetables > root crops > non-leafy vegetables. The approximate range of radiocesium transfer factor was found to be low in all plant groups and was comparable to those reported elsewhere in different soil types of temperate and tropical environments. A strong negative correlation between the obtained transfer factors and the distribution coefficient of the radionuclide in soil was found. It is recommended to adopt the newly derived parameters for the sensitive areas in Kuwait and other Gulf countries instead of using the generic parameters, whenever dose calculation codes are used. This will help to more accurately assess and predict the end results of the committed effective dose equivalent through ingestion pathway.
