  • The present electropalatographic study reports the production of the allophones. i.e., [l] and [r], of Korean tap /r/ and their coarticulatory characteristics in /$C{\'{a}}r#g$/ and /$C{\'{a}}r#i$/ sequences. The finding that tap /r/ involves a complete oral closure with less lingual contact, i.e., apico-frontalveolar coupling. than lateralized /r/ which involves apico-bladealveolar coupling and tongue dorsum lowering for adequate airflow through either side and/or both of the tongue body suggests that the two allophones of the tap /r/ have different lingual gestures. Moreover. in comparison with the tap. the lateral exerts longer lingual contacts. The mean ratio between them is 3.7. In the sequences /Car#g/. the two adjacent antagonistic segments (i.e., /r/ and /g/) show mutual coarticulation effects taking on features of adjacent segment. but either of them is precisely constrained without blocking the formation of involved major lingual gestures for the other segment. In sequences /Car#i/ occurs anticipatory V-to-C coarticulation but not vocalic carryover effects. In both sequences. the allophones reveal insignificant wordinitial consonantal carryover coarticulatory effects and insignificant speaker-specific lingual contacts.

  • According to the cognitive science research, the interaction intent of humans can be estimated through an analysis of the representing behaviors. This paper proposes a novel methodology for reliable intention analysis of humans by applying this approach. To identify the intention, 8 behavioral features are extracted from the 4 characteristics in human-human interaction and we outline a set of core components for nonverbal behavior of humans. These nonverbal behaviors are associated with various recognition modules including multimodal sensors which have each modality with localizing sound source of the speaker in the audition part, recognizing frontal face and facial expression in the vision part, and estimating human trajectories, body pose and leaning, and hand gesture in the spatial part. As a post-processing step, temporal confidential reasoning is utilized to improve the recognition performance and integrated human model is utilized to quantitatively classify the intention from multi-dimensional cues by applying the weight factor. Thus, interactive robots can make informed engagement decision to effectively interact with multiple persons. Experimental results show that the proposed scheme works successfully between human users and a robot in human-robot interaction.

  • Objective: This research measured physiological and psychological effects of Vibroacoustic stimulation(VA) to scapular and sacrum of supine position on the mattress. Background: When vibroacoustic stimulation applies to human body, it has a positive influence on physiological and psychological effects by stimulating the organs, tissues and cells of whole body. Method: This experiment was conducted to 10 normal males in two conditions: no stimulation and vibroacoustic stimulation. No stimulation experiment was executed as a supine position for 30 minutes without any vibrational stimulus, while vibroacoustic stimulation was transmitted by the vibrational speaker, which uses 40Hz frequency. Subjects had a laser Doppler flowmeter probe in scapular, sacrum, and also had 8 channel electroencephalogram(EEG) measurement sensor in the scalp. Blood pressure and skin temperature were measured in two conditions with an underlying posture for 30 minutes. Additionally, blood flow rate and EEG were measured before and after for two minutes on two conditions. Results: According to the vibroacoustic stimulation, blood flow rate and skin temperature were increased, while blood pressure was decreased. When using vibroacoustic stimulation compared to no stimulation, blood flow rate went approximately two times higher, and skin temperature also higher 3~4 times. Furthermore, the relative alpha power of brain wave was significantly increased when we applied to vibroacoustic stimulation. Conclusion: This experiment tested the VAT embedded in mattress in two conditions. According to this experiment, VAT decreases blood pressure, improves not only a physiological effect on blood flow rate as well as skin temperature, but also psychological functions by increasing relative alpha power. Application: The results of the publishing trend analysis might help physiological and psychological effects of vibroacoustic stimulation.

  • Objective : The thromboembolic events during neuroendovascular therapy (NET) are the major complications of concern that can be occasionally fatal. The thrombotic occlusion of the guide catheter for NET is thought to be the risk of the thromboembolic events. We have developed an idea for inventing the monitoring system of the continuous irrigation through the guide catheter. We herein present a unique invention of the guide catheter irrigation monitoring device. Methods : We have developed ideas for preventing the thrombotic occlusion of the guide catheter. In order to design a convenient device working in the practical use, we have consulted and shared the ideas with the electrical engineers about putting the invention. Results : The guide catheter irrigation monitoring device (GCIMD) consisted of three parts of optical sensor, main body and electric adapter. In brief, the basic principles of working of the GCIMD are as follows. The optical sensor is attached to the dripping chamber of the line to irrigation solution. The main body had the small light and speaker to make an alarm sounds. The sensor monitors the dripping of flush solution. If the dripping stops more than three seconds, a warning alarm has been activated. So, the operating physicians can concentrate and check the guide catheter irrigation. After the use of the GCIMD, there was no major thromboembolic complication in conjunction with the thrombotic occlusion of the guide catheter in our institute. Conclusion : We have developed a brilliant invention of the GCIMD for NET.

  • The meaning of the amendment to the Media Arbitration Act in our society is not limited to media companies. And it's not just a problem for a specific group. It expresses public value because it is an issue that can affect members of society as a whole and furthermore, it becomes a bill that can infringe or strengthen individual freedom guaranteed by the Constitution, but makes different arguments. Freedom of speech is not achieved in a day and should not be easily lost by someone. Although it is not a frequent problem, fatal threats arising from wrong media reports take away an individual's present and future. It is because of this problem that the responsibility is important. Freedom of speech and control are heading in different directions, but they are the same as the front and back of the coin. The freedom pursued is different, but it consists of one body. If freedom and responsibility of speech made up of one body criticize or ignore each other, the results are scattered into a distorted On the other hand, the flexion of responsibility without freedom serves as a speaker that conveys the ideology of some classes or represents the interests of a particular group. The fact that the media should act as the air of society means that it should represent the interests of the majority, make them aware of the rights of unfair or marginalized members, and be their strength.

  • As an information-oriented society comes, many people use PC and depend on database that network server has. However, the online data can be missed when a blackout happens and also a power failure effects on standard of judgment on Power Quality. Thus, it is reason of a trend using interruption-free live-line work when a trouble happens to power system. However, the 83% among the number of people who receive an electric shock experience when a laborer is doing interruption-free live-line works. In interruption-free method, the education and the training problem has been issued. However, we have a few instructors for that training. Furthermore, the trainees have short training period, just 4 weeks. In this paper, to develope the method that has no restriction of a time and place and reduce the wasteful materials, immersion type virtual reality(or environment) technology is used. The users of a 3D immersion type VR training system can interact with the system by doing same action in the real safe environment. Thus, it can be valuable to apply this training system to a dangerous work like as "Interruption-free live-line work exchanging COS(Cut-Out-Switch)". In this program, the user works with a instruction on the window and speaker and can't work other tasks until each part of the task completed. The workers using this system can use their hands and viewpoint movement as he is in a real environment but the trainee can't use all parts and senses of a real body with the current VR technology. Despite of this weak point, when we consider the trends of improvement in electrical devices and communication technology, we can say that 3D graphic VR application has a high potentiality.

  • In the current age of the information oriented society in which we live, many people use PCs and are dependant on the databases provided by the network server. However, online data can be missed during the occurrence of a blackout and furthermore, power failure can greatly effect Power Quality. This has resulted in the trend of using interruption-free live-line work when trouble occurs in a power system. However, 83% of the population receives an electric shock experience when a laborer is performing interruption-free live-line work. In the interruption-free method, education and training problems have been pinpointed. However, there are few instructors to implement the necessary training. Furthermore, the trainees undergo only a short training period of just 4 weeks. In this paper, to develop a method with no restrictions on time and place and to ensure a reduction in the misuse of materials, immersion type virtual reality (or environment) technology is used. The users of a 3D immersion type VR training system can interact with the system by performing the equivalent action in a safe environment. Thus, it can be valuable to apply this training system to such dangerous work as 'Interruption-free live-line work exchanging COS (Cut-Out-Switch)'. In this program, the user carries out work according to instructions displayed through the window and speaker and cannot perform other tasks until each part of the task is completed in the proper sequence. The workers using this system can utilize their hands and viewpoint movement since they are in a real environment but the trainee cannot use all parts and senses of a real body with the current VR technology. Despite these weak points, when we consider the trends of improvement in electrical devices and communication technology, we can say that 3D graphic VR application has high potentiality.

  • 최근 문학작품에 나타나는 괴물의 형상화는 '포스트휴먼' 시대의 인간 존재에 대한 비판적 상상력을 담고 있다. 특히 젠더적 시각에서 바라보는 괴물-비체의 문학적 재현은 근대적인 폭력과 억압적인 가부장 세계에 대한 여성 주체의 비판을 담고 있다. 본고는 김언희의 시와 한강의 소설을 중심으로 '비체'와 '괴물'의 문학적 재현이 지닌 젠더적인 상상력에 주목하고자 한다. 두 작가의 작품은 괴물-비체의 상상력을 통해 혐오와 숭고, 경이로움과 기형성을 넘나드는 실천적인 젠더 전략을 보여준다고 할 수 있다. 김언희의 시가 보여주는 괴물-비체의 전략은 미러링의 서술화법과 절단된 신체의 상상력으로 요약될 수 있다. 남성 화자를 흉내내는 미러링의 발화법은 최근 여성혐오의 문제와 관련하여 일부 페미니스트들이 전략적으로 활용하는 방식이기도 하다. 김언희의 시에서 미러링의 화법을 통한 '남성 되기' '남성 흉내내기'는 육체를 해체하는 절단의 이미지로 나타난다. 이와 같이 혐오와 기괴함을 끌어내는 비체의 서술 전략은 가부장적 지배 이데올로기에 대한 강력한 비판을 담고 있다. 한강 소설이 보여주는 괴물-비체의 전략은 식물되기와 채식-거식의 과정을 통해 구체화된다. 한강 소설에서 억압되었던 비체의 세계는 신체의 상징을 통해 몸의 감각으로 귀환한다. 여성의 신체로 표현되는 병리적 증상을 통해 억눌린 욕망을 깨닫는 소설 인물들은 적극적인 변신을 감행한다. 소설에 나타난 신체의 감각과 변화는 단순히 동물-남성-문명의 세계를 거부하는 것뿐만 아니라 근본적으로 인간과 비인간의 경계를 탐문하는 급진적인 물음을 지향한다. 두 작가의 작품은 괴물-비체의 상상력이 기존의 젠더 범주를 거부하는 것에 머무르지 않고 다양한 젠더 실천을 수행할 가능성을 보여준다.

  • 본 연구에서는 단순 세정의 개념이 아닌 복합감각 증진 개념의 헬스케어 목욕 시스템을 개발하고자 한다. 헬스케어 감성욕조를 디자인하기 위해 우선 타입별 특성을 고찰하였다. 이를 기반으로 복합감각 자극용 전신 욕조를 개발하였고, 이 전신욕조는 감성자극용 전신욕조 월풀, 시청각 감각 자극 기능이 구비된 욕조 커버, 제어용 소형 PC, 터치패널, DMB 패널, 시각 감성 증진을 위한 칼라 가변형 LED 무드 시스템과 스피커로 구성되어 있다. 제작된 복합감각 증진 개념의 헬스케어 욕조시스템의 특성을 고찰하기 위해서 목욕을 하는 동안 인체 자율신경계에 미치는 영향을 분석하였다. 전반적으로 목욕 상태에서의 심박변이율은 실험 중 교감신경에 비해 부교감신경이 계속 증가하는 것으로 나타났고, 목욕을 시작한지 15분이 경과하면 교감신경이 증가하고 부교감신경이 감소하여, 피험자가 목욕을 한지 15분일 때 가장 편안한 상태를 느끼는 것을 알 수 있었다. 또한 목욕 실험 결과 전후의 혈압이 최고 16mmHg까지 떨어진 것으로 나타났으나 맥박은 증가하였다. 이것은 심장으로부터 혈액의 유출량이 많아져 혈류량이 증가하는 것으로 복합감각 증진용 헬스케어 욕조 시스템을 이용한 목욕이 혈액 순환에 긍정적인 영향을 보였다. 본 연구의 결과를 가지고 복합감각 기능증진 헬스케어 목욕시스템의 사용성과 사용자의 생리분석을 통한 기초결과를 통해서 사용자의 생리변화를 분석함으로써 제품의 사용성과 사용자의 생리적 변화 및 감성 간의 관계를 보다 더 명확하게 밝혀낼 수 있으리라 기대한다.
