This paper presents a study on the fuzzy linguistic variable based approach for safety assessment of human body in ELF electromagnetic field considering power system states. To cope with the demand in modern industry, the power system becomes larger in scale, higher in voltage. The advent of high voltage system has increased the relative importance of field effects. The analysis of ELF electromagnetic field based on Quasi-Static Method is introduced while the power system is included to model the expected and/or unexpected uncertainty caused by the load fluctuation and parameter changes. In order to analyze the power system, Monte Carlo simulation method and contingency analysis method are adopted in normal state and alert state, respectively. In the safety assessment of human body, the approach based on fuzzy linguistic variable is employed to overcome the shortcomings resulting from a crisp set concept. The suggested scheme is applied to a sample system(modified IEEE 14 bus system) to validate the usefulness.

Korea's quarantine response to the novel coronavirus (coronavirus disease 2019 [COVID-19]) pandemic is based on the sacrifice of health professionals, especially public health doctors (PHDs) who were called out first and put in the first place in the country. PHDs performed major quarantine tasks, such as collecting samples from screening clinics and epidemiological investigations, in various parts of the country, including the Daegu area, where the first large-scale COVID-19 confirmed cases in Korea and explosively increased. Because of their position as fixed-term civil servants, however, PHDs' professionalism as doctors was ignored, and they were not properly compensated for their work. They were also exposed to problems such as a high risk of infection, mental suffering, and various human rights violations. We must prepare concrete measures to improve the fundamental treatment of PHDs and protect their human rights in order to prepare for a possible infectious disease pandemic in the future.

The current facility condition monitoring has disadvantages such as a slow inspection cycle, a risk of human casualties, and the need for a lot of time and money as the size of the structure is larger, because human access is required with limited use. Drones can reduce the risk of human casualties due to their good accessibility, and can compensate for the shortcomings of the current method by enabling monitoring on a wide scale. The goal of this study is to provide the current domestic monitoring process through benchmarking according to the recent research case of the US Department of Transportation (DOT) to suggest a process suitable for the domestic situation and the direction of future improvement measures.

Diagnosing reading disorders involves complex procedures to evaluate complex cognitive processes. For an accurate diagnosis, a series of tests and evaluations by human experts are required. In this study, we propose a quantitative tool to diagnose reading disorders based on natural reading behaviors using minimal human input. The eye movements of the third- and fourth-grade students were recorded while they read a text at their own pace. Seven machine learning models were used to evaluate the gaze patterns of the words in the presented text and classify the students as normal or having a reading disorder. The accuracy of the machine learning-based diagnosis was measured using the diagnosis by human experts as the ground truth. The highest accuracy of 0.8 was achieved by the support vector machine and random forest classifiers. This result demonstrated that machine learning-based automated diagnosis could substitute for the traditional diagnosis of reading disorders and enable large-scale screening for students at an early age.

This study look into the 3 stages which is distinguished by the usage of human in Man-Kyeong river. 'A nature based usage stage' is acknowledge the river itself and used only the tributary and built reservoir in a small scale from ancient to 1910s. 'A human based usage stage' is built the large scale reservoir at upper stream area and make the artificial waterway from 1920s. And the main stream is remodeled to protect the flood and get the agricultural land. 'A human and nature integration stage' is the main stream has a role not only the spill way but also clean water for inhabitants does together with river. The role and meaning of river is given newly. The development of technique and increase the need of the human is required the change in the role and meaning of river. The river is natural existence as it is, but the meaning and role is given by the human. Also it accompanied the change of the landscape in neighbor region. The natural river is controled the human life in the past, but it changed to social existence which is given the role and meaning by the human now.

Purpose: The purpose of this study was to investigate knowledge of cervical cancer, HPV and intention for vaccination in Korean soldiers on active duty. Methods: Participants were 494 army men aged 18 to 26 serving in D area. Knowledge of cervical cancer was measured using the 8 item scale developed by Han et al. (2007) and knowledge of HPV was measured using the 13 item scale developed by Pitts et al. (2009). Collected data were analyzed with t-test, $x^2$-test, and ANOVA. Results: Mean scores for cervical cancer and HPV knowledge were $6.03{\pm}1.52$ and $8.15{\pm}1.75$ respectively and vaccination intention was 75.6%. HPV vaccination intention had significant differences depending on knowledge about cervical cancer (${\chi}^2=12.76$, p=.001), and HPV (${\chi}^2=9.00$, p=.003), education (${\chi}^2=12.24$, p=.002), sexual intercourse after first meeting (${\chi}^2=11.79$, p=.003), and sexual education in the military service (${\chi}^2=12.27$, p=.001). Conclusion: When planning education program for men in military service, it is necessary to consider include content to increase knowledge of cervical cancer and HPV.

This study investigated the effects of triamcinolone acetonide by iontophoretic transdermal drug delivery on anti-inflammatory action into the human which had excentric exercise-induced delayed onset muscle soreness in the non-dominant arm. The degree of anti-inflammation was evaluated creatine posphokinase(CPK) by serum enzyme activity and subjective pain threshold by soreness muscle scale in clinical study. The results Were as follows; 1. In a subjective pain scale, all groups showed non-significant difference but, showed a tendency to decrease numerical value in human. 2. In the serum CPK level, iontophoresis group showed more significant reduction than other groups at 24, 48 and 72 hours. From the results, the iontophoresis with triamcinolone acetonide is more effective than using each groups. The continuous study is needed for many interesting issues of iontophoretic transdermal drug delivery in new future.

한국어 문법 연구에서 뿐만 아니라, 현대 언어학에서는 일반적으로 대명사들은 재귀적 대명사와 비재귀적 대명사라는 두 개의 구분된 통사 범주로 분류된다는 대명사의 이분법적 통사 분류 가설이 지배적이다. 그러나 최근 [Hertz 92ab]가 제시한 조응성의 등급(anaphoric scale)이라는 개념에 의거한 본 연구에서는 한국어 대명사들을 두 개의 구분된 통사 범주로 이분하지 않으며 오직 서로 다른 조응도(anaphoric degree)에 의해서만 구분하는 스칼라식 관점을 제안하였다. 한국어 대명사들의 조응도를 기술하기 위해 본 연구에서는 몇 가지 통사 의미적 준거 항목들을 제시하였다. 본 연구의 접근 방법은 그간 많은 연구들에 의해 밝혀진 바와 같은 대명사들의 다양하고도 이질적인 통사 의미 특성들을 자연스럽게 설명하여 줄 수 있다는 장점이 있다. 반면, 이와 같은 대명사들의 통사 의미적 다양성은 전통적인 이분법적 분류의 관점에서는 풀기 어려운 숙제로 남게 된다.

A large-scale culture of hepatitis A virus in human diploid MRC-5 cells was conducted. In a roller bottle culture, the virus was grown to a maximum titer in 3 weeks after infection. Over 95％ of the cell-associated virus was excreted after culturing the infected cells in suspension media without fetal bovine serum for 3 days. The cultured virus was inactivated with formalin, concentrated by ultrafiltration, and partially purified by ultracentrifugation in a non-ionic gradient medium of Renocal. Two separate peak fractions showing high anti-HAY ELISA titer were pooled and about 40％ of HAV antigen was recovered by this purification procedure. Of the partially purified vaccine, the protein pattern in SDS-PAGE and immunogenicity in mice were compared with a commercial HAV vaccine. In SDS-PAGE, the purified vaccine in this study and the commercial vaccine showed almost the same protein pattern. The seroconversion rate of the purified vaccine in mice was not different from that of the commercial vaccine. Therefore, we could prepare a good grade of HAV vaccine by a simple purification procedure although the purification itself was not completed.

Large scale display panel(LSDP) is a main component in the next generation main control rooms. LSDP is located at the front of VDU-based operator's workstation and plays an important role in providing operators with overall information of plant status through mimic diagram, text/digit, graph, and so on. A critical matter determined at the first stage of LSDP design is how much information is displayed, because the information density of LSDP affects operator's performance. Many human factors guidelines recommend low information density of displays to avoid degrade of operator's performance, but doesn't provide a useful limit of information density. In this paper, we considered information density as the number of plant parameters and investigated the proper number of plant parameters through a human factors experiment. The experiment with 4 subjects was carried out and response time, error, and heart rate variation as criterion measures were recorded and analyzed. As the results, it is identified that the proper number of parameters in a LSDP is about thirty.
