The status of small and medium-sized enterprises has been changed into more independent business entities rather than simply subcontractor so that the utilization of specialized knowledge has been much more necessary for the survival in the market. However, small and medium-sized enterprises, it is difficult to sufficient investment in knowledge services due to limited resources relative to large enterprises and demand for knowledge services business of government support is growing. For this reason, it is important to measure accurately the demand for knowledge services of small and medium-sized enterprises in knowledge management for effective utilization of knowledge service. In this study, we analyzed previous studies on small and medium-sized enterprises knowledge services that can be utilized in a comprehensive way. As a result, we developed knowledge service needs assessment model based on five critical success factors for continual growth and 12 types of knowledge service. This model has been modified and supplemented through expert meeting using delphi research method and topic modeling analysis using secondary data. This study is attempted to appropriately measure necessary knowledge services for small and medium-sized enterprises so that generated the evaluation model of knowledge service demands, comprehensively dealing with core knowledge services for many kinds of business entities. It is expected that the developed model will be a useful tool to understand and evaluate knowledge services demands of enterprises.

이 연구에서는 예비 화학교사의 수행평가 개발 과정에서 나타나는 교과교육학 지식(PCK) 요소의 특징을 분석하였다. 예비교사 8명이 연구에 참여하였고, 이들은 수행평가 워크숍 후 구상 단계, 구체화 단계와 조별 논의 단계를 거쳐 수행평가를 개발하였다. 활동 과정에 대한 녹음 및 녹화와 반구조화된 면담을 실시하였다. 분석 결과, 개별적인 개발 단계에서 나타난 PCK 요소는 과학 평가에 관한 지식에 편중되어 있었다. 교육과정, 교수 전략, 학생에 관한 지식의 비중은 낮았으며 학생에게 제공되는 피드백도 고려되지 않았다. 구상 단계보다 구체화 단계에서 평가의 공정성과 객관성을 중시하는 전통적 평가 지향이 강하게 나타났다. PCK 요소 사이의 연계는 구상 단계에서 과학 교수 전략에 관한 지식을 중심으로 이루어졌다. 구체화 및 조별 논의 단계에서 PCK 요소 사이의 연계는 거의 나타나지 않았다. 조별 논의에서 나타난 PCK 요소의 특징은 구체화 단계와 유사하였다. 조별 논의를 통하여 예비교사들이 고려하지 못했던 일부 PCK 요소가 보완되었으나 논의가 주로 전통적 관점에서 이루어졌다.

Purpose: This paper introduces the technology of prognostics for Industry 4.0 and presents its application procedure for fitness-for-service assessment of natural gas pipelines according to ISO 13374 framework. Methods: Combining data-driven approach with pipe failure models, we present a hybrid scheme for the gas pipeline prognostics. The probability of pipe failure is obtained by using the PCORRC burst pressure model and First Order Second Moment (FOSM) method. A fuzzy inference system is also employed to accommodate uncertainty due to corrosion growth and defect occurrence. Results: With a modified field dataset, the probability of failure on the pipeline is calculated. Then, its residual useful life (RUL) is predicted according to ISO 16708 standard. As a result, the fitness-for-service of the test pipeline is well-confirmed. Conclusion: The framework described in ISO 13374 is applicable to the RUL prediction and the fitness-for-service assessment for gas pipelines. Therefore, the technology of prognostics is helpful for safe and efficient management of gas pipelines in Industry 4.0.

Evaluating service lives of rubber materials at certain temperatures requires a destructive method (typically using elongation at break). In this study, a non-destructive method based on hardness change rate was proposed for evaluating the service life of chloroprene rubber (CR). Compared to the destructive method, this non-destructive method ensures homogeneity of CR specimens and requires a small number of samples. Thermal accelerated degradation test was conducted on the CR specimens at 55, 70, 85, 100, and 125℃, and the tensile strength, elongation at break, and hardness were measured. The results of the experiment were compared to those of the accelerated life evaluation method proposed in this study. Comparing the analyzed lives in the high temperature region (70, 85, 100, and 125℃), the difference between the service lives for the destructive method (using the elongation at break) and non-destructive method (using the hardness) was approximately 0.1 year. Therefore, it was confirmed that the proposed non-destructive evaluation method based on hardness changes can evaluate the actual life of CR under thermally accelerated degradation conditions.

Objectives: To determine the factors affecting the assessment of Oriental medical institutions under the Oriental Medical Institution Assessment System and thereupon, provide for some basic data and alternative measures for assessment of Oriental medical institutions. Methods: The researcher sampled 320 people employed by 26 Oriental medical institutions designated as model Oriental medical institutions subject to assessment in 2008 and 2009 and thereupon, used a structured and open-ended survey table for them to collect the data. The size of the final sample was n=302. Results: The Oriental medical institution staff were highly aware of the Oriental medical institution assessment (OMIA), After adjusting the other factors by multiple regression, the factors affecting such recognition were different significantly depending on age (those in their 30's), types of job (nurses and treatment assistants) and locations of hospital (GyeongSang-do). The staff expected the OMIA could helpful for improving facilities and system of hospitals, thus promoting satisfaction of patients. To do so, they felt it necessary to develop an assessment scale reflecting the special conditions besetting the Oriental medical institutions as well as the indices for improvement of Oriental medical service quality. Conclusion: It is hoped that this study will be followed up by future studies which will comparatively analyze Oriental medical institution staff's perception of the assessment system before and after its operation and thereby, suggest some ideal policy alternatives for assessment of the Oriental medical institutions. Furthermore, future studies are requested to research into Oriental medical institution staff's needs and consumers' needs as well in consideration of the characteristics of the Oriental medical institutions and thereupon, suggest some alternatives for continued education, development of the assessment tools, methods and policies.

Purpose: The aims of this study were to assess the presence of core patient safety practices in Korean hospitals and assess the differences in reporting and learning systems of patient safety, infrastructure, and safe practices by hospital characteristics. Methods: The authors developed a questionnaire including 39 items of patient safety staffing, health information system, reporting system, and event-specific prevention practices. The survey was conducted online or e-mail with 407 tertiary, general and specialty hospitals. Results: About 90% of hospitals answered the self-reporting system of patient safety related events is established. More than 90% of hospitals applied incidence monitoring or root cause analysis on healthcare-associated infection, in-facility pressure ulcers and falls, but only 60% did on surgery/procedure related events. More than 50% of the hospitals did not adopted present on admission (POA) indicators. One hundred (80.0%) hospitals had a department of patient safety and/or quality and only 52.8% of hospitals had a patient safety officer (PSO). While 82.4% of hospitals used electronic medical records (EMRs), only 53% of these hospitals adopted clinical decision support function. Infrastructure for patient safety except EMRs was well established in training, high-level and large hospitals. Most hospitals implemented prevention practices of adverse drug events, in-facility pressure ulcers and falls (94.4-100.0%). But prevention practices of surgery/procedure related events had relatively low adoption rate (59.2-92.8%). Majority of prevention practices for patient safety events were also implemented with a relatively modest increase in resources allocated. Conclusion: The hospital-based reporting and learning system, EMRs, and core evidence-based prevention practices were implemented well in high-level and large hospitals. But POA indicator and PSO were not adopted in more than half of surveyed hospitals and implementation of prevention practices for specific event had low. To support and monitor progress in hospital's patient safety effort, national-level safety practices set is needed.

Background: Selective health benefit was introduced for decreasing economic burden of patients. Medical devices with economic uncertainty have been covered as selective health benefit by National Health Insurance since December 2013. We aimed to analyze impact of selective health benefit to medical expenditure and provider behavior focused on electrosurgery (ultrasonic shears, electrothermal bipolar vessel sealers) for gastric cancer patients covered since December 2014. Methods: We used the National Health Insurance claims data of 2,698 patients underwent gastric cancer surgery between August 2014 and March 2015. Medical cost and patient sharing per inpatient day were analyzed to verify that covering electrosurgery increased medical expenditure and changed provider behavior from open surgery to endoscopic or laparoscopic surgery. Additionally, we analyzed the claim rate of medical device or goods relating gastric endoscopic and laparoscopic surgery. Results: Medical cost and patient sharing per inpatient day were increased after covering electosurgery as selective health benefit (39,724/1,421 won). However, there were no medical expenditure increases after adjusting claim of electosurgery and patient sharing was decreased 1,057 won especially. The coverage of selective health benefit did not increase the claim rate of medical device or goods related endoscopic or laparoscopic surgery, either. Conclusion: Covering electosurgery decreased patient economic burden and did not change of provider behavior. Expanding selective health benefit is needed to decrease economic burden of severe patients. Further study should evaluate the long term effect with accumulated data.
