Purpose: The purpose of this study was to develop a specialized education curriculum aimed at helping nurses prepare for running and managing a Maternal-Child Health Center (Postpartum Care Center). Method: This study was conducted by an academy and industry joint research group consisting of professors of Nursing, and nurses actually running a Postpartum Care Center. The group compiled job descriptions of nursing through document research, interviews and observation during site visits, surveys, and seminars. They then performed a feasibility study and developed the final curriculum. Result: The education curriculum is a 32-week(2semester) program compromised of a theory part (12 credits, 180 hours) covering maternal and infant care and business start-up and field practice (3 credits, 45 hours). Courses in the theory part include an antenatal care, overview and details of maternal care, starting a business and its management. Of these courses, the overview of a maternal care course was developed with web-based contents. Field practice is designed to give students opportunities to visit Postpartum Care Centers, observe the care provided, and get hands-on experience. Conclusion: The specialized education curriculum is a 32-week course comprised of 12 credits on theory of antenatal care, overview and details of maternal care, infant care, starting and operating a business and 3 credits of field practice.

Various approaches have been used in crack preparations and each of the approaches has advantages and disadvantages. Although the routing method has been widely used and seems to be the best approach among the approaches, it is not a complete solution for crack preparation. This paper compares and evaluates a pneumatic crack cleaning device (CCD) developed by Robotics and Intelligent Construction Automation group at Georgia Tech, over existing devices. Surveys were conducted to discover factors that affect the performance of crack/joint preparation work. Then, data for such information were collected via field tests for devices such as router, heat lancer, air blower and CCD. Performed field test results and follow-up interviews demonstrated that the utilization of CCD has potential to offer improvements in productivity, safety, and maintenance cost. An analytic hierarchical procedure (AHP) and economic analyses were conducted. The AHP analysis considered three factors including safety, quality and productivity while the economic analyses examined the alternatives in various ways. The results indicated that the CCD was ranked first and second for the AHP analysis and economic analysis, respectively. In conclusion, the field tests and results revealed that the utilization of CCD achieved satisfactorily in performance, quality, safety and control, and showed that it has high potential in crack cleaning practice.

Foot rot symptoms were repeatedly observed on plants of deltoid synurus (Synurus deltoides) growing in a field of the Wild Vegetable Research Institute located in Pyeongchang, Korea during disease surveys in July 2020 and June 2021. The symptoms appeared as wilting of the plant leaves, and the plant stems and petioles at or above the soil line turned dark and rotted. The incidence of diseased plants in the field was 5-10%. Five isolates of Phytophthora sp. were obtained from lesions of the diseased plants and investigated for their morphological and molecular characteristics. All the isolates were identified as Phytophthora cryptogea based on the morphological and molecular characteristics. Three isolates of P. cryptogea were tested for pathogenicity on deltoid synurus plants using artificial inoculation. All the tested isolates caused foot rot symptoms on the inoculated plants. The symptoms were similar to those observed in plants from the field investigated. To our knowledge, this is the first report of P. cryptogea causing Phytophthora foot rot in deltoid synurus.

The present study evaluated growth factors affecting oak community plantations through literature review and a field survey. Specifically, 41 related literature sources were analyzed and field surveys were conducted to collect growth data. Previous studies were analyzed to identify variables with high frequency of use. The frequency of use was in the order of tree size > environment > planting density > forest age. Analysis of factors impacting height and diameter growth revealed that the growth rate of species other than Quercus variabilis was negative in the field survey. This may be because of differences between the actual trees planted and specifications in the construction drawings, which may be attributed to the site conditions and decisions made by the project subject during construction. Furthermore, simple linear regression analysis was conducted with time, height at planting, density, and species code as the independent variables and growth rate as the dependent variable. A strong positive linear correlation was noted between height and diameter. This work builds a foundation for developing a forest restoration model and simulation program based on a regression model derived from the four variables tested.

Ground subsidence in urban areas due to excessive development and degraded underground facilities is a serious problem. Geophysical surveys have been conducted to estimate the distribution and scale of cavities and subsidence. In this study, electrical resistivity tomography (ERT) was performed near an area of road subsidence in an urban area. The subsidence arose due to groundwater leakage that carried soil into a neighboring excavation site. The ERT survey line was located between the main subsidence area and an excavation site. Because ERT data are affected by rapid topographic changes and surrounding structures, the influence of the excavation site on the data was analyzed through field-scale numerical modeling. The effect of an excavation should be considered when interpreting ERT data because it can lead to wrong anomalous results. A method for performing 2D inversion after correcting resistivity data for the effect of the excavation site was proposed. This method was initially tested using a field-scale numerical model that included the excavation site and subsurface anomaly, which was a loosened zone, and was then applied to field data. In addition, ERT data were interpreted using an existing in-house 3D algorithm, which considered the effect of excavation sites. The inversion results demonstrated that conductive anomalies in the loosened zone were greater compared to the inversion that did not consider the effects of excavation.

교사 양성 과정에서 현장교육 프로그램은 예비교사들에게 교육활동을 경험하도록 함으로 올바른 교육관을 형성하고 신념의 변화를 가져오게 하는 중요한 기회를 제공해 준다. 이에 본 연구는 참관수업과 교육실습의 현장교육 프로그램이 예비과학교사들의 인식론적 교육관의 변화에 어떠한 영향을 미치는지 살펴보았다. 이를 위해 예비과학교사들을 대상으로 참관수업과 교육실습 기간에 따라 3차례 설문조사와 면담을 실시하였으며 모든 설문조사에 참여한 28명의 응답에 대해 결과를 분석하였다. 연구결과 예비과학교사들은 참관수업 전 전통적인 교육관인 객관주의 인식론적 교육관이 형성되어 있었으나, 참관수업과정에서 관찰한 현장교사의 영향으로 객관주의 인식론적 교육관이 다소 강해 진 것으로 나타났다. 그러나 교육실습과정에서 직접 수업에 참여해 봄으로써 현대적인 교육관인 구성주의 인식론적 교육관으로 유의미하게 변한 것으로 나타났다. 이에 현장교육 프로그램이 예비과학교사들의 교육관 변화에 긍정적 또는 부정적인 영향을 미칠 수 있음을 확인할 수 있었다. 따라서 예비과학교사들이 현장교육 프로그램을 통해 구성주의 인식론적 교육관을 획득하거나 강화시킬 수 있는 기회를 제공하기 위해 교사 양성기관과 학교 현장과의 유기적이고 지속적인 협력 체제를 마련해야 할 것이다.

최근 기후변화로 인해 비탈면이 증가하고 있으며 2019년 동해안 및 부산지역 사면붕괴 발생 및 2020 곡성 산사태 등 급경사지 재해에 대한 위험성이 증가하고 있는 추세이다. 특히 국립공원은 대부분 산지로 이루어졌으며 급경사지 재해에 대한 위험성이 증가하고 있다. 국립공원의 지반은 노령화 되고 기후변화로 인해 암반의 풍화 및 절리가 가속화되고 있어 사면붕괴 및 낙석이 증가하고 연간 탐방 객수는 증가하는 추세로 이용자수가 많은 다중이용시설에 인접한 급경사지 관리가 필요한 실정이다. 본 연구에서는 GIS를 활용해 국립공원 다중이용시설에 영향을 미치는 위험 급경사지를 분석하고 현장조사를 통해 검증하였다. 국립공원 다중이용시설 인접 급경사지를 추출하기 위한 과정으로 DEM에서 경사도를 제작하고 34도 이상인 사면을 추출하였다. 추출된 사면의 최대높이와 최소높이 차이로 급경사지 기준에 부합하는 사면을 확인하였으며 사면방향 분석을 통해 다중이용시설에 영향을 미치는지 확인하였다. 이후 정밀 항공영상과 현장사진을 분석하여 최종적으로 4개소의 위험지점을 확인하였으며 현장조사를 실시하였다. 현장조사 결과 4개소 모두 급경사지로 나타났으며 3개소는 D등급, 1개소는 C등급으로 나타나 붕괴위험지역으로 관리가 필요할 것으로 확인되었다. GIS를 통해 추출한 급경사지 모두 위험한 것으로 나타나 GIS를 통한 급경사지 추출이 타당할 것으로 판단된다.
