현재 자신의 건강에 대한 관심이 증가함에 따라 스마트폰을 이용한 건강 관련 어플리케이션이 많이 개발되고 있다. 건강 관련 어플리케이션을 이용하면 실제로 건강을 관리하는데 있어 많은 장점들이 있지만 대부분의 스마트폰 사용자들은 사용하지 않으며, 건강 관련 어플리케이션의 존재를 모르는 사람들도 있었다. 즉 건강 관심도에 비해 건강 관련 어플리케이션의 사용성이 떨어진다는 뜻이다. 따라서 본 논문에서는 만보계 기능을 이용하는 카디오트레이너라는 어플리케이션의 사용성 테스트를 실시하여 사용성을 떨어뜨리는 요인을 파악하고 원인을 분석한다.

This paper presents the efforts of the studies for improvement of spin characteristics of KTX-1 #02 through rotary balance test, forced oscillation test and spin mode analysis. During the full scale development design stage, we had fullfilled a lot of spin flight test, spin mode analysis. Based on all of the efforts, KTX-1 had been developed as a successful trainer with excellent spin characteristics.

In recent years, there has been an increasing demand for healthcare services that can periodically monitor health status and maintain health by increasing the weight training population. However, injuries in the absence of trainer are increasing with the increase in the number of members in the fitness training center. Therefore, there is a need for a system that can periodically monitor the user's exercise state and assist in systematic and safe exercise even when the trainer is absent. In this study, we developed an auto training system that can effectively manage the exerciser while supporting the strength movement. The auto training system consists of a cable mount module, a control module, and a training information monitoring module. In order to evaluate performance of the developed system, the assistant force tests are carried out. Experimental results showed that the assistant force works well when the exerciser is out of power.

The flight control law of developed flight control computer(DFLCC) is developed based on operation flight program of advanced trainer aircraft full scale development final configuration. The flight control law design is used common use development tool in GUI(Graphic User Interface) environment. The flight control law transformed to C-Code is reflected in OFP. The OFP is verified by the standardized verification process. But, before standardized verification process, we need preliminary verification process such as similarity of flight control law and reliability of developed HILS. Similarity of flight control law is verified by comparing the aircraft response of advanced trainer aircraft and those of the developed control law. Also, reliability of developed HILS is verified by comparing the aircraft response of HILS and Non-real time simulation result. This paper verifies similarity of developed control law and reliability of HILS environment as comparing aircraft response.

This study was conducted to evaluate the effect of current dietetic internship program. The survey sample was dietetic practitioners who were charged with a training for dietetic students. The questionnaire requested information about demographic information, experience of guidance for the dietetic student, self evaluation as trainer, fortification Items in university education, and difficulties of the internship program. Data was analyzed using SAS for windows(version 6.12), Descriptive statistics were used such as means, standard deviations, frequency distribution and percentages. Comparison of mean differences was analyzed using t-test and ANOVA. Participants identified how effective the current internship program was. Result indicated that the effectiveness was not high(2.81), and under 29 years old age group, under 6 years work experience group, and contracted foodservice group had positive opinion of the program significantly. Under 29 years old age group, evaluated themselves as a good trainer. The results revealed that respondents wanted to be fortified the practical training courses in school curriculum.

A performance simulation program for the turboprop engine (PT6A-62), which is the power plant of the first Korean indigenous basic trainer KT-1, was developed for performance prediction, development of an EHMS (Engine Health Monitoring System) and the flight simulator. Characteristics of components including compressors, turbines, power turbines and the constant speed propeller were required for the steady state and transient performance analysis with on and off design point analysis. In most cases, these were substituted for what scaled from similar engine components'characteristics with the scaling law. The developed program was evaluated with the performance data provided by the engine manufacturer and with analysis results of GASTURB program, which is well known for the performance simulation of gas turbines. Performance parameters such as mass flow rate, compressor pressure ratio, fuel flow rate, specific fuel consumption and turbine inlet temperature were discussed to evaluate validity of the developed program at various cases. The first case was the sea level static standard condition and other cases were considered with various altitudes, flight velocities and part loads with the range between idle and 105% rotational speed of the gas generator. In the transient analysis, the Continuity of Mass Flow Method was utilized under the condition that mass stored between components is ignored and the flow compatibility is satisfied, and the Modified Euler Method was used for integration of the surplus torque. The transient performance analysis for various fuel schedules was performed. When the fuel step increase was considered, the overshoot of the turbine inlet temperature occurred. However, in case of ramp increase of the fuel longer than step increase of the fuel, the overshoot of the turbine inlet temperature was effectively reduced.

A workplace trainer is required to have profound theoretical and technological knowledge, sufficient experience and problem-solving ability in order to play the role of a competent trainer and assessor for the apprentices and experienced worker students who are participating in the Work-Learning Dual System of the company. This study has introduced a Degree-linked Highly Skilled professional Course in Korea and proposed an optimized standard education model for the training of high-quality workplace trainers. It is expected that this study will contribute greatly to the training of highly skilled professionals for efficient implementation of the Work-Learning Dual System and stable institutional settlement of the Highly Skilled professionals Course as the first empirical study on the training of highly skilled professionals.

Current U-Healthcare has become specialized in Wellness center in the prevention of future health care concept of a health center, treatment. Wellness is the development of which has been emerging field of fitness system to evolve along with the key areas of U-Healthcare. Traditional Fitness system, one between the trainer and the user: 1. Consultation was only possible, the number of trainers are limited, this problem can be reduced individual coaching time existed as more number of users who can receive coaching at certain times of the day. In this paper, we design a mechanism that allows management by grouping field value of a DB table in the user's BMI(Body Mass Index) index and fitness trainer system to efficiently coaching a plurality of users similar BMI index.

In this paper, we proposed a development of M-learning smart-trainer content for improving the learning ability of military education. Learners of time and space constraints beyond quickly and accurately can learn with the goal, each subject by partial learning, and repetition, the whole learning quickly and easily by selecting efficiently to help you learn a m-Bizmaker with applications was designed. Experiment targets the military company of two, first aid courses were conducted for the evaluation. Traditional collective comparison group teaching methods, the proposed content, teaching methods applied in the experimental group were selected. The proposed learning applications using smart instructor for verification of learning, with which to compare, test subjects were compared with each of 49 subjects, the results p<.005 level, there was difference among the two groups. Therefore, the proposed application using a smart trainer after class proved that contribute to improving achievement.
