This paper describes development contents and flight tests of an ACMI simulator based on LVC integrating architecture. ACMI is the system that provides air combat training and ground bombing training for improving fighting efficiency, that is the live simulation involving real people to operate real systems. ACMI simulator was developed for technic acquisition of LVC interoperability by using data link communication. ACMI simulator simulated maneuvering of a fighter by operating an UAV, a fighter can be distinguished from an UAV by maneuvering characteristics. This study proposes maneuvering simulation method by using flight data of the UAV, and performed its flight test for verifying similarity of fighter maneuvering.

Objectives : The purpose of this study was to examine the problems with the current practical examination, to suggest some of the right directions for that and to facilitate the improvement of the exam. Methods : The subjects in this study were the selected professors involving professors in charge of practice and the selected clinical dental hygienists who had ever served as the graders of the national practical exam. Results : A direct practical test was required in the national practical exam (77.3%), and educational facilities(79.2%)(p<0.05). They didn't put confidence in the national practical exam(81.0%) nor viewed the items about the removal and detection of dental calculus as appropriate(58.5%), either. Specifically, the items were considered to be more inappropriate by the professors in charge of practice(74.3%) than by the other professors and clinical dental hygienists(p<0.05). Concerning ways of administering the national exam, the largest group preferred that a professional evaluator should evaluate students in person by visiting their colleges(66.8%). Conclusions : The above-mentioned findings illustrated that both of the dental hygiene professors and the clinical dental hygienists thought the current national dental hygienist practical exam would absolutely be necessary since it exerted a great influence on education and educational facilities, and that the national exam should be improved to gain more confidence, to solve comprehensive problems and to ensure the efficiency of administration.

The objective of this paper is to identify the fatigue properties of carbon-fiber composite which is widely applied for the development of aircraft structures and obtain data for full-scale fatigue test. The durability and damage tolerance evaluation of composite structures is achieved by fatigue tests and parameters such as fatigue life factor and load enhancement factor. The specimens are made with carbon-fiber/epoxy UD tape and fabric prepreg. Fatigue tests are performed with several stress ratios and lay-up patterns. The Weibull shape parameters are analyzed by Sendeckyj model and individual fatigue lives with Weibull distribution. And the fatigue life factor and load enhancement factor considering reliability are evaluated.

Purpose: With the purpose of educating and producing outstanding paramedics by enhancing their competencies, this study aimed to make policy suggestions to re-establish the education system and improve the national examination and the certification scheme. Methods: This study used focus group interviews and questionnaires to collect data. Totally, there were 277 subjects, including experts from the education and field. Data were collected from September 9 to 20, 2016, and analyzed using SPSS 22.0. Results: To strengthen the curriculum of paramedics, this study suggested 27 courses with 94 credits as the standardized curriculum and derived 9 core competencies of paramedics. For the national examination, this study suggested consolidating written test subjects, adding scenario questions to practical tests, and applying critical criteria to simple practical tests that performs a procedure, grading these tests on a pass/fail basis. In addition, this study suggested converting certification into license, reflecting paramedics' healthcare job characteristics. Conclusion: The quality of emergency medical services in Korea will improve when those with core competencies that originated from the standardized curriculum based on the results of this study acquire their certification through the national test scheme, and the certification management system creates a virtuous cycle to further enhance paramedics' professionalism.

The general requirements to achieve the structural integrity of the airframe are described in the military specification, MIL-STD-1530A. One of these requirements is the durability and damage tolerance of the airframe, which should be shown through the analysis and test based on the related specifications. This paper introduces the full scale durability test to evaluate the structural safety and durability of the basic trainer, KT-1. The test was performed according to the procedure in the military specification. The flight by flight load spectrum was developed by KT-1 fatigue load criteria and used for the durability test. The durability test had been performed for 4 service lives and was completed successfully. Therefore, it was shown that KT-1 airframe satisfied the durability requirements.

The field of Construction Engineering leads 1970's industry of the Korea. As a result of development of construction technology, It secure national competitiveness winning overseas contracts many kinds of plant, building and so on. In this situation, it is the most important task to cultivate and select construction teacher to train construction education and to foster construction skilled workers be going into the field of construction. This Study attempts to offer useful implications about the improvement of the Teacher Certification Examination through analyzing that will have a strong influence and be a standard in educational direction to cultivate construction teacher.

The purpose of this study was to investigate the recognition for improvement of the Korean Dental Hygienists' Licensing Examination(KDHLE). The subjects were 1,048 dental hygienists were surveyed. either in person or through mail. Data was collected using a self administrated questionnaire from July 1 to July 20, 2008. The data were analysed with frequency and $x^2$-test using the SPSS 15.0 windows. For the inquiry where adequacy of subjects of the KDHLE regarding to evaluation of standard duty achievement ability in the real field was asked, 404(39.5%) answered 'Yes', and 680(66.9%) was answered 'Yes' for necessity of changing current subjects of the KDHLE. For the inquiry about the number of questions in the KDHLE, 353(34.6%) answered that current number of questions is 'Inappropriate' and advisable way of improving KDHLE subjects, 463 (45.4%) answered 'enhancing problem solving ability through unifying subjects', the highest of all. About practical examination methods, 647(67.3%) was answered 'Should be modified'. For methods of dental hygienist practical examination, 'clinical demonstration on patients' received the highest number of votes 628(63.6%). According to the above results, most of active dental hygienists at presence expect the alteration of current KDHLE and new items which are reliable for globalization by testing problem solving ability through unified subjects must be introduced.

To recruit nurses with skills, the hospital must evaluate the skills of the applicants. But objective evaluation of the skills is a difficult. Many hospitals are using written examination or oral test only and are not testing the nursing skills directly when they recruit new nurses. OSCE(Objective Structured Clinical Examination) is a method developed for the evaluation of clinical skills objectively. In this study, 16/20 nurse managers of one university-affiliate hospital were assembled for the project of developing 7 OSCE modules by themselves, and then they ran OSCE using those modules for 40 nursing students. They scored nursing skills of the students using checklists they designed. The whole process was proceeded phase by phase using step-wise approach model. The project was successful; inter-personal consistency of the scores were high; nurse managers became confident in objective skill evaluation; subjective responses for this project were favorable. The hospital adopted OSCE in recruitment process thereafter. This experience might be applied to other hospitals who want to recruit nurses with skills.
