This paper presents an investigation into the operational comparison of SPOT triangulation to build GCP library by analytical plotter and DPW (digital photogrammetric workstation). GCP database derived from current SPOT images can be used to other image sensors of satellite, if any reasons, such as lack of topographic maps or GCPs. But, general formulation of a photogrammetric process for GCP measurement has to take care of the scene interpretation problem. There are two classical methods depending on whether an analytical plotter or DPW is being used. Regardless of the method used, the measurement of GCPs is the weakest point in the automation of photogrammetric orientation procedures. To make an operational comparison, five models of SPOT panchromatic images (level 1A) and negative films (level 1AP) were used. Ten images and film products were used for the five GRS areas. Photogrammetric measurements were carried out in a manual mode on P2 analytical plotter and LH Systems DPW770. We presented an approach for exterior orientation of SPOT images, which was based on the use of approximately eighty national geodetic control points as GCPs which located on the summit of the mountain. Using sixteen well-spaced geodetic control points per model, all segments consistently showed RMS error just below the pixel at the check points in analytical instrument. In the case of DPW, half of the ground controls could not found or distinguished exactly when we displayed the image on the computer monitor. Experiment results showed that the RMS errors with DPW test was fluctuated case by case. And the magnitudes of the errors were reached more than three pixels due to the lack of image interpretation capability. It showed that the geodetic control points is not suitable as the ground control points in DPW for modeling the SPOT image.

The purpose of this study was to develop the NCS-based cooking practice education method by using the full learning model and to confirm its effect. The study design was a pre-post test of the non-equality control group. The subjects of this study included 28 students in the experimental group and 27 students in the control group. The experimental group participated in the NCS-based cooking practice training using the complete learning model, and the control group received only cooking practice training based on the full learning model. The data were collected during the second semester of 2016 and analyzed by SPSS WIN 23.0. The results of this study were as follows: First, homogeneity test showed that pre - homogeneity such as general characteristics, cooking ability, and knowledge of cooking theory were achieved (p>0.05). Second, the experimental group recognized that its cooking ability was high. With respect to the ability to cook food, the ability to cook, and the ability to prepare food ingredients (p<0.01), personal hygiene management, cooking hygiene management, and cooking safety management abilities were not significant. The mean value the experimental group was high. Third, the final theoretical knowledge score was not significant. The average score in the experimental group (69 points) was 5 points higher than that in the control group (64 points). This was about two times higher than the score of 37 points in the first stage preliminary survey. Finally, the final performance score was significant (p<0.05), and the score in the experimental group (89 points) was 5 points higher than that in the control group (84 points). Therefore, the NCS-based cooking education method is confirmed to be an effective method, especially for improvement of the practical ability, improvement of theoretical knowledge, and achievement of perfect learning standards.

본 연구의 주요 목적은 서로 다른 측지기준계인 동경측지계와 세계측지계간의 좌표 변환을 위한 연구이다. 이를 위하여 Bursa-Wolf 모델, Molodensky-Badekas 모델 및 Veis 모델을 이용하여 7변환 계수를 결정하였다. 또한 동경데이텀으로부터 세계측지계로 변환하기 위한 다중회귀식 방법도 적용하였다. 공통점 중에서 비상사성인 과대 오차인 점을 분석하고 제거하여 935점의 국가기준점 성과를 변환 계수 결정을 위한 공통점으로 이용하였다. 각 모델별로 결정한 변환 계수를 적용하여 상사 변환에 의한 3, 4등 삼각점 9,917점에 대한 좌표변환을 수행하였으며 변환 정확도를 평가하였다. 그 결과, Bursa-Wolf 모델과 Molodensky-Badekas 모델을 이용하여 결정한 변환 계수가 Veis 모델에 비하여 더 적합하다는 것을 알 수 있었다. 다중회귀식에 의한 변환 정확도는 상사 변환 모델보다는 다소 저하되는 경향을 보였다. 변환 계수의 추정 정밀도와 변환 정확도 및 변환 잔차의 패턴을 분석한 결과, 최적의 국가 좌표변환 모델은 Molodensky-Badekas 모델이라고 판단된다.

Purpose: The purpose of the study was to investigate the effects of infection control knowledge and nursing work environment on infection control performance among general hospital nurses. Methods: A total of 138 nurses from four general hospitals located in G and P cities participated in this descriptive study. The collected data were analyzed using t-test, ANOVA, Pearson's correlation coefficients, and multiple regression. Results: The average mean score was 21.41±1.92 points out of 25 for infection control knowledge, 2.53±0.33 points out of 4 for nursing work environment, and 4.62±0.40 points out of 5 for infection control performance. In the final analysis, the variables that had the greatest influence on infection control performance were the nursing work environment (β=.32, p<.001), working department (β=.19, p=.014), and knowledge (β=.19, p=.016). Conclusion: This study showed that nurses with a better nursing work environment, employment in general department, and more infection control knowledge delivered superior infection control performance. Therefore, to improve infection control performance, it is necessary to enhance the nursing environment and develop practical education programs for augmenting infection control knowledge.

Quantitative risk assessments are related to implementing hazard analysis and critical control points (HACCP) by its potential involvement in identifying critical control points (CCPs), validating critical limits at a CCP, enabling rational designs of new processes, and products to meet required level of safety, and evaluating processing operations for verification procedures. The quantitative risk assessment is becoming a standard research tool which provides useful predictions and analyses on microbial risks and, thus, a valuable aid in implementing a HACCP system. This paper provides a review of microbial modeling in quantitative risk assessments, which can be applied to HACCP systems.

Objectives: This study aimed to evaluate the educational effect of the Field Epidemiology Specialist Training Program for School Nurse which composed of 18hours curriculum. Method: The subjects were 797 who participated in the 2005 training program. Data was collected with structured questionnaires(knowledge on the control of communicable disease 15 items, attitude 15 items, and confidence in practice 14 items, demographic characteristics 4 items) before (January) and after (July to October) programs in 2005. Results: Knowledge on the control of communicable disease was improved from 9.7 points (possible range : 0-15) before program to 11.9 points after program. Attitude was improved from 53.6 points (possible range : 15-60) before program to 55.7 points after program. Confidence in practice was changed from 45.9 points (possible range : 14-56) before program to 50.0 points after program. Even though all three areas were improved after educational program, knowledge showed the largest change among them. Conclusion: We can conclude the educational program was effective because knowledge, attitude, and confidence in practice on the control of communicable were statistically significantly improved after educational program. Further educational program is recommended to be operated to get more improvement in attitude and confidence in practice. And short-term continuing educational program is needed to maintain and refresh the information on the control of communicable diseases in schools.

국가나 지방자치단체에서 관리하는 기준점들은 다른 측량작업 및 지형정보구축과 밀접한 관계가 있으며, 전국토의 지리적 위치 기준이 되는 국가의 중요한 자산이다. 그러나, 이런 기준점들이 현재 각종 대장으로 관리되고 있으며, 관리자가 건설이나 도시개발에 따르는 기준점 망실, 보수 및 신설 등으로 현황을 손쉽게 갱신할 수 없고, 또한 사용자가 변경된 기준점 현황을 신속하게 파악할 수 없는 실정이므로, 본 연구에서는 기준점 유지관리업무를 효율적으로 수행하고 사용자가 편리하게 활용할 수 있도록 기준점 관리시스템을 개발하는데 그 목적이 있다. 시스템 개발을 위해, 기준점 관리업무 분석 및 요구사항을 고려하여 입력, 갱신, 검색, 네트워크, 분석 및 통계 기능 등으로 설계하였고, Mapobject를 엔진으로 Visual C++과 Visual Basic을 이용하여 구축하였다. 시스템에 사용된 도형 자료는 1/5,000 수치지도와 수치지적도면을 이용하였고, 각 기준점에 대한 속성자료는 점 명, 도엽 명, 경위도 및 TM좌표, 관측연월일, 기준점 사진 등을 활용하였다. 기준점 통합관리 시스템을 구축한 결과 기준점과 관련된 각종 도형정보와 속성정보, 위치정보를 통합관리할 수 있었다.

In this paper, a 3D shape optimization algorithm which guarantees a smooth optimal shape is presented using parameterized sensitivity analysis. The design surface is parameterized using Bezier spline and the control points of the spline are taken as the design variables. The parameterized sensitivity for the control points are found from that for nodal Points. The design sensitivity and adjoint variable formulae are also derived for the 3D non-linear problems. Through an application to the shape optimization of 3D electromagnet to get a uniform magnetic field, the effectiveness of the proposed algorithm is shown.
