The main purpose of this research is to show 351 Gwangju female high school students regarding the relationship between the general environment cause, stress level, anxiety degree, habit of eating meals, the amount of nutrient and the guideline for food life. The following is the result for this research. The average of the height was 161.04cm, the weight was 51.65 kg and the average BMI was 19.92 kg/㎡ for this surveyed female high school students. Due to the outcome of the average of BMI, the female students all seemed to be normal. Most of the surveyed students seemed to live in a nuclear family, and their monthly allowance was 3-5 million (Korean) won which had the 48.7% of the most. The average of surveyed students for social support was 34.39, the stress for life was 62.16, anxiety degree was 31.17, and the guide for eating was 37.24. When adding the outcome of the survey of the social support and stress for life, divide each part into 4 sections, and after analyzing the result, it has shown that when the stress and social support was high, the outcome has shown the highest of 9.0%. But the graph did not show statistical significance. When adding the outcome of the survey of stress for life and anxiety degree, divide each part into 4 sections, and after analyzing the result, the outcome has shown that when having the most stress with high anxiety it has 11.1% and when having the least stress with low anxiety has 11.4% with having statistical significance(p<0.001). When adding the outcome of the survey of guide for eating and stress for life, divide each part into 4 sections, and after analyzing the result, the outcome has shown that when having the least stress with keeping the guide for eating 10.3% and when having the most stress with not keeping the guide has 11.1% with having statistical significance(p<0.001). When adding the outcome of the survey for stress, divide each part into 4 sections, and after analyzing the result, the outcome has shown that a surveyed student’s daily nutrient compared, the amount of potassium is 1,823mg when they have less stress and this would be a high amount(p<0.05). Through this research, we can understand that female high school student get stress from social support, anxiety degree and the habit of eating meals. These causes the bad affect to the student, therefore, the school and at home, we need to give attention to the students to help control their stress. By controlling the stress with the right way, the young youth can make a better eating habit. Through this way, the youth can protect oneself from outside, and even have a good habit of eating even when one is growned-up.

室內 模型試驗을 통한 시멘트 그라우트의 地盤 浸透性能 分析

송영수 忠南大學校 大學院 2010 국내박사

Cement grout is most widely used beyond the limited application of colloid and pure chemical fluid all over the world. When grout is used for waterproofing of grounds, important roles are played by fluidity, particle size and bleeding. The most important element which determines their characteristics is the water/cement ratio of grout. In order to improve the efficiency of ground saturation, micro cement with a smaller average diameter is used in addition to ordinary Portland cement. Moreover, the form of injection is relevant to ground conditions, mixing ratio and diameters of cements. Therefore, depending on the ground conditions and the characteristics and conditions of cement grout, the saturation of cement milk may not happen in some area. Therefore, the improvement of grounds through injections may not be enough while the adoption of grouting methods may not be appropriate. In order to evaluate the effects of injections through grouting, actual grouting in field is most efficient which on the other hands requires high costs and much time. Therefore, simpler and more practical experimental methods are necessary which can survey the appropriateness of grouting and injection effects. In South Korea, we neither have the standards nor the devices to simulate grouting experiments in a laboratory test. This research developed injection equipment for pressure permeation which can evenly simulate various grouting tests in a laboratory and produced the standards for specimen production. The analysis of the test of injection for pressure permeation showed that the efficiency of injection becomes linearly higher as the water/cement ratio increases. Smaller the average diameters of materials are, more efficient become injections. It was found that the relative size of grout material with respect to the soil particles controled the transfer distance of the grout particles. When the cement has the specific surface area higher than 8000cm2/g, clogging of pore spaces occurred, resulting in restricted propagation of grout particles. It was also found that there was a threshold value in the size of grout particle. Below the threshold value, the permeation of grout particle did not increase with the decreasing particle size of grout material. Moreover, the comparison of efficiency of injection between maisem 8000, colloidal super cement shows that the latter with a relatively smaller average diameter achieves more efficient injection than the former.

In this study, the effect of decreased surface tension of a volatile organic compound(VOC) during air sparging was evaluated using a laboratory-scale two-dimensional physical model packed with sand water containing dissolved toluene as a representative VOC. Six sets of air sparging experiments were performed: the first at a surface tension of 71 dyne/㎠ with no surfactant applied; and the second at a surface tension of 52 dyne/㎠ due to 100 mg/L of anionic surfactant at gas flow rate(100, 200, 400 ㎤/min). Under the experimental conditions used m this study, the sparging influence zone estimated at the lower surface tension was about 2.5 times that estimated at the high surface tension. Also the rate of toluene removal by air sparging was found to be much faster at the lower surface tension. The final mass recoveries at low and high surface tensions at 400 ㎤/min of flow rate were 73.39 % and 10.41 %, respectively. The effect of decreased surface tension and increased temperature on non-aqueous phase liquids(NAPL) removal during air sparging was evaluated using a laboratory-scale sand column physical model packed with sand containing decane as a representative DNAL. Two sets of air sparging experiments were performed; the first at a surface tension 52 dyne/㎠ due to 100 mg/L of anionic surfactant at elevated temperature; the second at a surface tension 52 dyne/㎠ due to 100 mg/L of anionic surfactant at ambient temperature. The rate of decane removal at elevated temperature during air sparging was found to be much faster than that without heating.

퍼지 군집화 분야는 처음 제안된 이후 FCM 알고리즘을 시작으로 PCM, FPCM, PFCM 등의 알고리즘들이 개발되어 왔다. 그러나 FCM 알고리즘은 모든 데이터에 대한 거리에 기본을 둔 멤버쉽을 기초로 하기 때문에 노이즈에 약한 면을 보여 왔으며, 이를 개선하기 위해 PCM, FPCM, PFCM 등 많은 알고리즘이 제안 되었다. 그러나 이와 같은 알고리즘들은 초기값 및 계산양, 파라미터 수와 같은 문제가 증가하였으며 이 또한 노이즈에 완벽히 대응 할 수 없었다. 이 논문에서는 IFCM 알고리즘의 제안을 통해 노이즈에 대해 효과적으로 학습 할 수 있는 군집화 알고리즘을 제안하였다. 이를 몇 가지 실험을 통하여 증명하였다. ABSTRACT Since its first proposal, the fuzzy clustering field has seen the developments of algorithms including PCM, FPCM, PFCM, etc. starting with the FCM algorithm. The FCM algorithm has, however, shown a weakness to outliers since it is based on the membership on the ground of distances to all data, many other algorithms to improve this shortcoming have been proposed such as PCM, FPCM, PFCM, etc. But these algorithms have shown the increasing problems like the initial value, the amount of calculation, the number of parameters, and thus could not respond perfectly to outliers either. This paper suggests a clustering algorithm able to learn effectively about outliers through suggesting the IFCM algorithm. This is supported through a few experiments.

레거시 PLC 시스템에서 OPC-UA 지원 소프트웨어의 설계 및 구현

송영수 서울시립대학교 일반대학원 2021 국내석사

산업 환경에서 공정 제어 시스템은 4차 산업 혁명 시대에 맞춰 자동화와 연결성이 극대화되고 있다. OPC-UA는 제어 시스템에서 계층간의 수직적 접근과 장치간의 수평적 접근을 가능하게 하여 산업 환경에 상호 운용성을 지원하는 4차 산업 혁명의 이상적인 프로토콜로 간주된다. PLC 시스템에서 OPC-UA의 쉬운 개발과 유지 보수성을 위한 PLCopen 기술 문서가 작성됐다. 이 기술 문서는 OPC-UA 서버의 정보 모델과 OPC-UA 클라이언트의 서비스에 대응하는 함수 블록들을 명세한다. 하지만 산업 환경에는 OPC-UA를 활용할 수 없는 레거시 장비들이 사용되고 있다. 이를 위해 레거시 장비를 교체하는 것은 비용과 시스템 안전성 문제를 초래할 수 있다. 그러므로 레거시 장비에 OPC-UA를 활용하기 위한 다양한 연구들이 진행됐다. 본 논문은 레거시 장비들 중 PLC 장비에 한정하여 OPC-UA를 지원하고자 한다. 지원하기 위한 방법으로 첫째는 레거시 장비에 OPC-UA를 제공할 수 없는 원인들을 정의한다. 둘째로 선정한 OPC-UA SDK의 특성과 타겟 시스템을 고려해 정의한 원인들의 해결 방법을 제시하고 간소화된 PLCopen 기술을 설계한다. 마지막으로 설계한 소프트웨어를 개발하고 타겟 시스템을 모사하는 실험 환경을 구성하여 소프트웨어의 동작과 성능을 검증한다. OPC-UA 서버의 성능 지표는 CPU 사용량과 데이터가 생성된 시점으로부터 외부 OPC-UA 클라이언트가 데이터를 관찰하기까지의 지연 시간이다. 이 성능 지표들은 읽기와 구독 서비스로 검증하였다. OPC-UA 클라이언트는 처리하는 노드 수를 달리해가며 소프트웨어의 컴포넌트 별로 함수 블록의 실행 시간을 측정하였다. In the industrial environment, process control systems are maximizing automation and connectivity in line with the era of the Fourth Industrial Revolution. OPC-UA is considered an ideal protocol for the Fourth Industrial Revolution, which enables vertical access between layers and horizontal access between devices in a control system to support interoperability in the industrial environment. PLCopen technical documentation has been written for easy development and maintenance of OPC-UA in PLC systems. This technical document specifies the information model of the OPC-UA server and the function blocks that correspond to the services of the OPC-UA client. However, legacy devices that cannot utilize OPC-UA are being used in industrial environments. To this end, replacing legacy devices can lead to cost and system safety issues. Therefore, various studies have been conducted to utilize OPC-UA for legacy devices. This paper seeks to support OPC-UA only for PLC equipment among legacy devices. As a way to support, the first defines the causes of the inability to provide OPC-UA to legacy devices. Secondly, we present a solution to the defined causes and design a simplified PLCopen technology, considering the characteristics of target systems and the selected OPC-UA SDK. Finally, we develop the software and construct an experimental environment that mimics the target system to verify its behavior and performance. The performance indicators of an OPC-UA server are the CPU usage and the delay from when the data is generated to when the data is observed by an external OPC-UA client. These performance indicators are validated by read and subscription services. The OPC-UA client measured the execution time of functions blocks by each component of the software, varying the number of nodes handled.
