        鄭鎭亨 단국대학교 1987 論文集 Vol.21 No.-

        This experiment was performed to study the relationship between masseter muscle activity and occlusal equilibrium. Five dental students who have clicking sound and muscle pain were participated in this experiment. E.M.G. was checked by M.E.M-3102 on bilateral masseter muscles, and mandibular movements were checked by M.K.G. and E.M.G. before and after occlusal equilibrium. Velosities and vertical views were recorded and evaluated. The results were as followings. 1. Muscle activity of masticatory side was elevated than contralateral side before occlusal equilibrium 2. Muscle activity of masticatory side was decrease, and contralateral side was increased after occlusal equilibrium 3. Masticatory cycle pattern was altered after occlusal equilibrium in vertical view.

        정진형,조재현,김승훈,최안렬,이상식 한국정보전자통신기술학회 2021 한국정보전자통신기술학회논문지 Vol.14 No.2

        According to the World Agricultural Productivity Report, the current annual average growth rate of agriculture is 1.63%, which is lower than 1.73% to support the world's 10 billion people, which is growing by 2050. The demand for food, feed, and bioenergy is not growing enough to continue to meet the demand, and it is predicting a future food shortage. The purpose of this study was to create a regional irrigation control model for the purpose of reducing the production cost of crops, increasing production, and improving quality, and presenting a model that can give advice to farmers who start farming in the region. Therefore, through the measurement device of the Ministry of root and Environment, the data of the Ministry of root and Environment of the crop is collected, and the parameters for making an irrigation control model are set, and the data is extracted by applying the parameters to the collected data, and the irrigation of the area where the data is collected A study was conducted to suggest a control model. 세계 농업 생산성 보고서에 따르면 현재 농업의 연평균 성장률은 1.63% 수준으로 2050년까지 증가하는 세계 인구 약 100억 명을 지원하기 위한 성장률 1.73% 보다 낮은 수준이며 이는 세계 농업의 생산성은 2050년까지 세계 인구의 식량, 사료, 바이오에너지 수요를 지속적으로 충족시킬 수 있을 만큼 증가하지 않고 있으며 미래의 식량난을 예고하고 있다. 본 연구는 농작물의 생산비용 감소, 생산량 증대, 품질향상 등을 목적으로 지역별 관수제어 모델을 만들고 해당지역에 농사를 시작하는 농부들에게 조언을 줄 수 있는 모델을 제시하는 것을 목적으로 진행되었다. 이에 근권환경부 측정 장치를 통해 작물의 근권환경부 데이터를 수집하고, 관수제어 모델을 만들기 위한 매개변수를 설정하고, 수집된 데이터에 매개변수를 적용하여 데이터를 추출하고 이를 분석하여 데이터를 수집한 지역의 관수제어 모델을 제시하는 연구를 진행하였다.

        Development of an algorithm for Detecting Symptom level in patients with Scleroderma

        정진형,이기영,김민영,김남선,이상식 한국정보전자통신기술학회 2015 한국정보전자통신기술학회논문지 Vol.8 No.5

        In this study, locality of scleroderma was detected. Diagnostic method is difficult for scleroderma (skin curing; Scleroderma), and it is done by comparing the images of the normal subjects to the scleroderma patients, after performing monochrome processing. The saturation, brightness, and contrast are adjusted, and they were converted by using the process of Well Filter. As a result, the images were able to be used to clearly distinguish the symptoms of scleroderma. In addition, in a video of a healthy person, the line of sight of the observation given the image of scleroderma patients above sea level of height as 0 °is to implement the closing process to the rear Well Filter even only in so that the horizontal plane, and out at intervals of graph the amplitude difference of the video have I asked. The diagnostic criteria were determined for the healthy subjects and the scleroderma patients.
