The automotive seat comfort evaluation was to begin a key aspect in seat design. It depended largely on the basic mechanical aspect such as geometric parameters of seat, choice of suspension system and cushion material used. Until recently, seat comfort evaluation advanced to evaluate subjective sensitivity of human. The external literatures showed in the last decade, there have been very few attempts to establish and document automotive seat comfort evaluation. In 2006 Smith, D. proposed the statistically reliable tool in giving a numeric rating for set comfort and the tool was used in the many country. On the other hands, we, in Korea, had not the reliable tool for the automotive seat comfort evaluation. So that, we studied to develope the questionnaire for seat comfort evaluation based on Smith, D.(2006) and some studies. As a result, we developed 36 contents for the automotive seat comfort evaluation with the help of professional in Korean automotive industry. Here, 36 contents were identified as the dimensions that represent the human sensitivity and psychological feeling on comfortable seat. Also, we derived the priorities for the 36 contents by using analytic hierarchy process (AHP), based on the judgments of 30 experts and drivers. This study will help the designers and developers clarify the conceptual and abstract aspect of the design evaluation by proposing a more systematic and process-oriented method.
In this paper, I focused on analyzing Yeoheon Chang Hyeon-gwang's literary theory and his prose in the genealogy of Confucian scholars in Chosun. Through this study, I would like to examine the trend of concentrating on 16th century when we treat the literary tendency of Confucian scholars. With this goal, I tried to seek the direction which was pursued by Confucian scholars who lived during the 17th century. Yeoheon tried to construct the spirit of humanities cosmically as an aim of his life, study, and literature. And he had a new understanding of human independence by suffering from Japanese invasion in the late of 16th century. He insisted that only human can realize the spirit of humanities on a cosmic base. He also thought that the morality(道) could be settled only by literature(文). We may interpret this concept as a progressive idea about literature comparing to the former Confucian scholars. On the other hands, Yeoheon tried to accept the literary theory of former scholars such like Park Young, Cho Sik, and Seong Woon who embraced Taoism. Yet he erased the color of Taoism in the field of topic, and he also tried to keep his distance from them in the field of literary form. This concept actually came from Lee Hwang's opinion, while Yeoheon tried to rouse scholar's independence. Through above, we may realize that the Confucian scholars of 17th century were not just imitators of 16th century. They tried to examine the former study and also tried to renew the theory.
As the phrase 'solitude death' implies, solitude generally has a negative characteristic as an object to avoid. But on the contrary, Nietzsche attempts to accept solitude and even affirms it in his overall philosophy. This study is about the authentic meaning of Nietzsche's solitude concept, aiming to clarify what true meaning solitude has to Nietzsche. This study will examine the 'external situation that humans face today' first. To do this, the study will consider the situation that humans who lost the earth and homeland faced in the period when God is dead. This study will then look at 'memory' and 'oblivion', as human's internal situations. And following that, this study will examine what meaning 'creativity' has to Nietzsche, which has a close relationship with those internal situations. Lastly, the meaning that 'body' and 'dance' imply to Nietzsche and what relationship these have with true solitude will be presented. Human is the being who can not avoid solitude whether they want it or not. Even though we make whatever effort we can to run away, solitude is unavoidable. The smart phone that makes me feel emptiness when I don't hold it on my hands, the hobbies which attract and force us to do, and new products which make us feel lonely if we don't buy them, don't they prove these efforts? What meaning does solitude have to humans that we have no other way but to run away from it like this? By understanding the authentic meaning of Nietzsche's solitude concept, we can change our view point on solitude so we can eventually accept 'solitude' as something that we must truly embrace and affirm, instead of something we must run away from.
Using passive electric field sensor which operates in non-contact mode, we can measure the electric potential induced from the change of electric charges on a sensor caused by the movement of human body or hands. In this study, we propose a new method, which utilizes PLN induced to the sensor around the moving object, to detect one's hand movement and extract gesture frames from the detected signals. Signals from the EPS sensors include a large amount of power line noise usually existing in the places such as rooms or buildings. Using the fact that the PLN is shielded in part by human access to the sensor, signals caused by motion or hand movement are detected. PLN consists mainly of signals with frequency of 60 Hz and its harmonics. In our proposed method, signals only 120 Hz component in frequency domain are chosen selectively and exclusively utilized for detection of hand movement. We use FFT to measure a spectral-separated frequency signal. The signals obtained from sensors in this way are continued to be compared with the threshold preset in advance. Once motion signals are detected passing throng the threshold, we determine the motion frame based on period between the first threshold passing time and the last one. The motion detection rate of our proposed method was about 90% while the correct frame extraction rate was about 85%. The method like our method, which use PLN signal in order to extract useful data about motion movement from non-contact mode EPS sensors, has been rarely reported or published in recent. This research results can be expected to be useful especially in circumstance of having surrounding PLN.

Power plant engineering industry obtains EPC plan project and delivers results about electricity, measurement, machinery, and piping and so on. Its works are taken by projects. Although power plant engineering composes 2~5% of whole EPC project cost, it's one of the fundamentals because it affects process after planning step a lot. However, domestic power plant engineering companies' project performance ability is insufficient and there's a need for systematic performance. Thus, this study defined related factors of successful performance and analyzed the priority among them through analytical hierarchy process. All respondents recognized experience, knowledge, and communication as important factors. Administrators considered knowledge, experience, and communication. But hands-on workers considered experience, knowledge, human resources. Those who have experience in oversea project considered process, experience, human resources. However those who don't have experience in oversea project considered knowledge, experience, and communication. Recognition of important factors varies by the position and work experience of members.

Objects : The purpose of this study is to investigate the effect of Su-Gi therapy for Bell's palsy by using Y-system(Yanagihara's unweighted grading system). Methods : We investigated 25 patients with Bell's palsy who had visited in the M, H Korean medicine hospital in Gyeonggi Province from December 27th, 2010 to April 8th, 2015. The Su-Gi therapy was done by 1 times daily. And each patients had been treated more than 25 days. We evaluated the change of them by using Y-system. Results : 1. We investigated 25 patients with Bell's palsy. 80% of the patients were females(20 patients), 20% of the patients were male(5 patients). The average age of patients was 47±15.15. The average period of Adm. treatment was 64% of the patients(16 patients) have left facial palsy, 36% of the patients(9 patients) have right facial palsy. 2. The mean Y-system score before treatment was 17.80±6.2, and the mean score after 25th days treatment was 33.68±4.0. Changes in the mean Y-system Score for each case according to the treatment days was increased significantly. 3. The mean Y-system score after 4th days treatment had increased by an 1.24±2.7 as compared to before treatment, the score after 10th days treatment was 8.7±4.7, the score after 14th days treatment was 11.84±5.8, the score after 20th days treatment is 14.72±6.7, and the score after 25th days treatment was 15.88±6.9. Every score was significantly increased. Conclusions: 1. Su-Gi therapy can be defined that is mainly using the hands to touch or movement of the human body skin, meridians and acupuncture points, muscles, joints and so on. And that is the treatment to communicate and harmonize to the meridians and acupuncture points, and to prevent of diseases, and to keep health. 2. All names of An-Gyo, An-Ma, Jum-Hyul, Chu-Na, massage, and so on should be referred to as Su-Gi therapy. And that individual names are to be classified and separated as the type or method of Su-Gi therapy. 3. The results of the treatment of Hwidam's Su-Gi therapy for Bell's palsy by using Y-system were significant.
These days, ISIS terrorists have been expanding not only to european countries, but also to asian countries so South Korea is no longer safe from terrorists' attacks. Especially, 'soft target terrorism' makes many people maximizing fear of terrorism because it is caused by small groups - those who are armed with small arms and light weapons - and they are able to carry out hit and run attacks on civilian targets. It poses even more dangerous to kill massively. That is why November 2015 Paris attacks and January 2016 Jakarta attacks killed and injured many people because of 'soft target terrorism.' Therefore, the South Korea has also recognized the seriousness of terrorism by ISIS. The study has shown the precautionary measures about 'soft target terrorism' and how to defend against 'soft target terrorism' by looking through overseas examples. It is for the possibilities of 'soft terrorism' in South Korea because of the expansion of ISIS. As a result, 'soft target terrorism', caused by ISIS, could happen in South Korea. The counterplan is as in the following. First of all, 'soft target terrorism', which is collaborated with ISIS and domestic terrorists, could be caused by negative awareness of foreign residents and xenophobia so the public should change stereotypes about the foreign residents and there should be legislation about racial discrimination enacted by parliament and the government must practice the law. Second, the Korean anti-terrorism laws should be modified to minimize violations of human rights, related to the Korean citizens' personal information, and to stop the concentration of power into the hands of one law enforcement. Third, the government has to develop and to initiate the refuge&evacuation simulation, which prepares for 'soft target terrorism' and minimizes the damages if terrorists attack hot spots like central commercial areas or event halls.
The aim of this retrospective research was to investigate the influence of the patient's arm position on radiation dose and scanning during CT. Chest CT image created image degradation, artifact and overdose to the patient due to the difference of the chest thickness. Therefore, the patient's arm should up position during the CT chest examination. In 2012, 1,642 patients underwent chest CT examination in Seoul K hospital. 118 chest CT examination performed hands down position. The average DLP value of the CT chest arm up examination was 275 $mGy{\cdot}cm$. The average DLP value of the CT chest arm down examination was 312.46 $mGy{\cdot}cm$. In the retrospective study with same patient, The average DLP value of the CT chest examination arm up vigorously was 267.5 $mGy{\cdot}cm$. The average DLP value of the CT chest arm down examination was 307.5 $mGy{\cdot}cm$. Chest CT scan without raising arm created linear artifact due to the lack of X-ray photons which is the thickest part of the human body of shoulder area. In conclusion, arm positioning patients' arms above the shoulders at CT of the chest increases image quality and substantially reduces effective radiation dose.

This study was undertaken to identify nursing professionalism perceptions among nursing students who had completed a semester of simulation-based education, and to provide the basis for presenting direction of the simulation curriculum that helps in the emergence of a positive nursing professional in future. Data obtained from focus group interviews of study participants determined 17 semantic categories and 6 themes through the process of identifying, comparing, and categorizing meaningful concepts. The perception of nursing students regarding the profession after simulation-based education include 'realization of professionalism', 'ethics and emotions as professional human subjects', 'cultivation of communication skills', 'integrative thinking for problem solving', and 'foundation', and also the importance of a 'foundational knowledge body' and 'reflection of self-capacity'. The results of this study reflect on 5 intuitional areas of a nursing professional: professional self-concept, social awareness, nursing expertise, nursing room role, and independence of nursing. The results of this study indicate that in order to enable nursing students to experience nursing professional intuition through simulation-based hands-on training, it is necessary to actively revise and apply courses for the development of a positive nursing professional intuition through simulation education.
As virtual realty has become an issue of providing immersive services, in the area of virtual realty, it has been actively investigated to develop user interfaces for immersive interaction. In this paper, we propose a gesture recognition based immersive user interface by using an IR LED embedded helmet and data gloves in order to reflect the user's movements to the virtual reality environments effectively. The system recognizes the user's head movements by using the IR LED embedded helmet and IR signal transmitter, and the hand gestures with the data gathered from data gloves. In case of hand gestures recognition, it is difficult to recognize accurately with the general recognition model because there are various hand gestures since human hands consist of many articulations and users have different hand sizes and hand movements. In this paper, we applied the Mixture-of-Experts based gesture recognition for various hand gestures of multiple users accurately. The movement of the user's head is used to change the perspection in the virtual environment matching to the movement in the real world, and the gesture of the user's hand can be used as inputs in the virtual environment. A head mounted display (HMD) can be used with the proposed system to make the user absorbed in the virtual environment. In order to evaluate the usefulness of the proposed interface, we developed an interface for the virtual orchestra environment. The experiment verified that the user can use the system easily and intuituvely with being entertained.
