본 연구는 간호 대학생들의 약물용량계산 능력을 개발, 증진하기 위해 학습용 스마트폰 어플리케이션을 개발하고 평가하기 위한 것이다. 충분한 자료를 근거로 콘텐츠를 구성한 후에 교육용 시스템으로 구현하는 과정으로 개발하였고, 전문가 집단에 의해 평가받았다. 간호대학생 37명을 대상으로 4주간의 중재 후, 참여도에 따른 자료를 SPSS WIN 18.0을 활용하여 분석하였다. 그 결과 어플리케이션의 사용정도에 따라 학습목표의 성취도(${\chi}^2$=10.90, p=.004), 업무 적용도(Z=2.86, p=.004), 수학적 자신감은 유의하게 증진(Z=3.07, p=.002)되었으나, 학업적 효능감에는 차이가 없었다. 본 연구에서 개발된 어플리케이션은 간호 대학생들의 약물용량계산 능력을 강화하는 데 도움을 줄 수 있는 교육용 프로그램이라 여겨지나, 보다 효과적으로 약물계산역량을 향상시키기 위해서는 학업적 효능감을 높이고, 참여를 적극적으로 격려하는 어플리케이션이 개발되어야 할 것이다.

Objective: The aim of this study was to determine the effect of abdominal-compression belt in one leg standing on balance in normal adult. Background: With the effects of increased intra-abdominal pressure, the abdominal-compression belt is contributing to a static balance control. However, specific study is still insufficient. Method: Forty subjects were randomly allocated to two groups: control(n=20) and experimental group(n=20), respectively. The experimental group used an abdominal-compression belt, whereas the control group did not that. All subjects were educated using pressure biofeedback unit and ultrasound imaging for exact application by abdominal-compression belt. Main outcome measurement was used a general stability index, fourier harmony index, weight distribution index, and fall index in tetrax balance system. Results: Experimental group improved significantly on general stability, only 2 factors(eyes closed with head turned forward and eyes closed with head turned backward) among fourier harmony index, and fall index, However, weight distribution index did not revealed significant difference. Conclusion: The findings suggest that application of abdominal-compression belt could be effective on improving balance ability in one leg standing of normal adults. Application: The results of the abdominal-compression belt might help to control balance in workers.

Purpose: This study was conducted to investigate out the effects of power by body application of weight training that can increase vertical jump, standing long jump, and medicine ball throw that are important factors for power ability. Methods: Sixteen in normal adult were participated in this study. The subjects were divided into the upper limb weight training group(N=16), the lower limb weight training group(N=16) and they exercised during a four-week period of time, three times a week, 70 minutes each, and the each group did take part in any exercise program. To evaluate the changes in power were measured by using the vertical jump, standing long jump, and medicine ball throw. The data was analyzed with a SPSS 18.0 program. Results: The results showed that the vertical jump, standing long jump were significantly increased in the upper limb weight training group(p<.01) and medicine ball throw was significantly increased in the both group(p<.05). However, there were that showed not significantly differences in all power items between two groups after experiment(p>.05). Conclusion: It was concluded that the weight training were effective in enhancing the power ability. Also, can be considered effective the better lower limb weight training group than upper limb weight training group.

Terahertz (THz) represents the portion of the electromagnetic radiation between the microwave and the infrared region and is within the frequency range of 0.1-10 THz. The ability of THz waves to pass through a wide variety of packaging materials, combined with their ability to characterize the molecular structure of many substances makes it an attractive tool for the application of food quality and safety management. This review provides current information on application of THz spectroscopy/imaging technology for food quality and safety management. The THz spectroscopy/imaging technology has been shown to be useful for detecting foreign bodies, vitamin/moisture, pesticides, antibiotics, melamine etc. However, major barriers to the adoption of THz spectroscopy/imaging for food quality and safety management include THz signal loss in heterogeneous food matrices, high costs of sources and detectors, and absence of a library for the wide group of food compounds. Further research is needed to overcome these barriers.

As Large Language Models (LLM) like OpenAI's ChatGPT[1] continue to grow in popularity, new applications and services are expected to emerge. This paper introduces an experimental study on a smart web-builder application assistance system that combines Computer Vision with GUI object recognition and the ChatGPT (LLM). First of all, the research strategy employed computer vision technology in conjunction with Microsoft's "ChatGPT for Robotics: Design Principles and Model Abilities"[2] design strategy. Additionally, this research explores the capabilities of Large Language Model like ChatGPT in various application design tasks, specifically in assisting with web-builder tasks. The study examines the ability of ChatGPT to synthesize code through both directed prompts and free-form conversation strategies. The researchers also explored ChatGPT's ability to perform various tasks within the builder domain, including functions and closure loop inferences, basic logical and mathematical reasoning. Overall, this research proposes an efficient way to perform various application system tasks by combining natural language commands with computer vision technology and LLM (ChatGPT). This approach allows for user interaction through natural language commands while building applications.

Background: This study was to investigate the effect of non-invasive transcranial direct current stimulation due to hemiplegic patients due to stroke on temporal and spatial gait ability. Design: Randomized sham controlled trial. Methods: For the study method, 42 patients with hemiplegia due to stroke were randomly assigned to 14 patients each, and the general walking group, tDCS walking group, and tDCS (sham) walking group were subjected to 5 times a week, 30 minutes a day, and 6 weeks. In the temporal gait variables of hemiplegic patients due to stroke, the effect of the gait time, gait cycle, single support, double support, swing phase, stance phase, gait speed, cadence were measured. In spatial variables, one step length and one step length were measured. Results: As a result of the study, the EG group significantly increased in the step time, gait velocity, and cadence of the paralysis side in the comparison of temporal walking variables between groups according to the application of tDCS of walking ability in hemiplegic patients due to stroke patients(p<.05). In the change in spatial walking variables between groups according to the application of tDCS, the step length and stride length of the EG group showed a significant increase. Both the comparison of temporal and spatial symmetry walking variables between groups according to tDCS application was not significant(p>.05) Conclusion: As a result, tDCS has an effective effect on the improvement of the gait ability of stroke patients. In particular, it is an effective method of physical therapy that can improve the cadence and speed of gait, which can be combined with the existing gait training to effectively increase the gait of hemiplegia due to stroke patients.

The purpose of this study was getting the information for successful application to the national curriculum and students' core competencies enhancement, through investigation about competencies discussed in 2015 revised national curriculum development process and analysis about perception of 150 elementary school teachers in study. The results were as follows : Communication skill is considered to be the most important. Thinking ability what has been important traditionally is the middle of the rankings. Elementary school teachers think that a competency is specific to a subject. From this point of view, Creative/Scientific Problem-Solving Ability is the most important in science. They think that the enhancing of the ability of inquiry performance is highlighted in current science class. On elementary school teachers' awareness, inquiry model is the most effective in enhancing of scientific thinking and the ability of inquiry performance. And STS instruction model is in the other. PBL learning model and experimental inquiry model is the most effective in enhancing a competency has the highest feasibility like scientific thinking or the ability of inquiry performance.
