Rheumatoid arthritis (RA) is a connective tissue disease involving the larynx in 30 % of the patients. Foreign body sensation, hoarseness, and cough are common symptoms in laryngeal involvement. An urgent tracheostomy is required when acute airway obstruction occurs in case of bilateral vocal fold paralysis. The most common cause of bilateral vocal fold paralysis in RA patients is a cricoarytenoid joint arthritis. Laryngeal nerve degeneration is rare cause of bilateral vocal fold paralysis in RA patients. In this case report, an emergent tracheostomy was performed on a 64-years-old male patient with acute dyspnea, and concurrent involvement of RA on laryngeal nerve and cricoarytenoid joint was revealed by laryngeal electromyography and histopathology. The vocal fold mobility was restored after 3-months medical treatment.

Ophthalmomyiasis rarely occurs worldwide, and has not been reported in Korea. We present here a case of ophthalmomyiasis caused by Phormia sp. fly larva in an enucleated eye of a patient. In June 2010, a 50-year-old man was admitted to Dankook University Hospital for surgical excision of a malignant melanoma located in the right auricular area. He had a clinical history of enucleation of his right eye due to squamous cell carcinoma 5 years ago. During hospitalization, foreign body sensation developed in his right eye, and close examination revealed a fly larva inside the eye, which was evacuated. The larva was proved to be Phormia sp. based on the morphology of the posterior spiracle. Subsequently, no larva was found, and the postoperative course was uneventful without any complaints of further myiasis. This is the first case of ophthalmomyiasis among the literature in Korea, and also the first myiasis case caused by Phormia sp. in Korea.

Protective clothing for firefighters typically consists of a flame resistant outer shell and inner layers. The inner layers are generally composed of a moisture barrier and a thermal barrier. On performing the task in fire place the heat and perspiration generated from the body become trapped inside the protective clothing. Those heat and moisture result into heat-stress and physical fatigue of fire fighter, which hinder the work. Therefore, the system of clothing designs and material layers must be chosen carefully to balance protection and comfort. 3 kinds of protective clothing of 3 layer structure were used in the experiment of physiological comfort. From the comparison of wear trials with the 3 kinds of layers in firefighters clothing, it indicates that the moisture dissipation of A+B2+C was highest, following A+BI+C andA+B3+C. And the heat dissipation of A+BI+C and A+B2+C were better than A+B3+C. In the protective clothing with A+B3+C, heat and perspiration generated through exercise remained in clothing system long and caused discomfort.

A vehicle driving simulator is a virtual reality device which makes a man feel as if he drove an actual vehicle. Unlike actual vehicles, the simulator has limited kinematical workspace and bounded dynamic characteristics. So it is difficult to simulate dynamic motions of a multi-body vehicle model. In order to overcome these problems, a washout algorithm which controls the workspace of the simulator within the kinematical limitation is needed. However, a classical washout algorithm contains several problems such as generation of wrong sensation of motions by filters in tilt coordination, requirement of trial and error method in selecting the proper cut-off frequencies and difficulty in returning the simulator to its origin using only high pass filters. This paper proposes a washout algorithm with new tilt coordination method which gives more accurate sensations to drivers. To reduce the time in returning the simulator to its origin, an algorithm that applies selectively onset mode from high pass filters and return mode from error functions is proposed. As a result of this study, the results of the proposed algorithm are compared with the results of classical washout algorithm through the human perception models. Also, the performance of the suggested algorithm is evaluated by using human perception and sensibility of some drivers through experiments.

The acupuncture procedures in Hwangjenaekyung (黃帝內經) was different to modern ones in many aspects. Especially, the role of pulse diagnosis in acupuncture was totally different and the pulse diagnosis was essential part in acupuncture therapy in Hwangjenaekyung era. We found four noteworthy features on the pulse diagnosis before and after acupuncture in Hwangjenaekyung : (1) Pulse diagnosis was a mandatory process in acupuncture (2) Doctors who used pulse diagnosis in 12 meridians (十二經脈遍診脈法), pulse diagnosis in 9 points of 3 body parts (三部九候脈法), and comparative pulse diagnosis between radial artery and carotid artery (人迎寸口對比脈法) followed the former rule ((1)). (3) The major pulse features to detect before and after acupuncture were conversion between the vacuous pulse (虛脈) and the replete pulse (實脈), and conversion between slippery pulse (滑脈) and rough pulse (澁脈). (4) Deukki (得氣, Deqi) was synonym of Kiji (氣至), and it referred to the changes of arterial pulse, not the sensation followed by acupuncture manipulation.

After reviewing literatures of Han dynasty or earlier that recognize tumor, bump or mass, we concluded as follows. The recognition or study on tumor, bump or mass started at least Seoju(西周) Dynasty or earlier, and academic system was developed since earlier Han Dynasty(漢代). Until Han Dynasty, main characters that recognize Tumor, bump or mass include Jong(腫), Yang(瘍), Yu(瘤), Yeong, Chang (瘡), Ong(癰), Jeo(疽), Jeok(積), Chwi(聚), Byeok(癖), Jing, and Ga, Hyeon that firstly appeared in Southern and Northern Dynasties(南北朝), and Am(癌) that firstly appeared in Song Dynasty[宋代] can also be considered as significant characters. The main perception of cancer(腫瘍) until Han Dynasty was started by understanding the concept of the word Yu(瘤) and developed through visual, tactile sensation and symptom observation of following 2 categories, One is tumor, btm1p or mass which is expressed in outer body like Yeong, Jong(腫), Chang(瘡), Yang(瘍), Ong(癰), and Jeo(疽), The other is tumor, bump or mass which is expressed internally like Jeok(積), Chwi(聚), Byeok (癖), Jing, and Ga.

The present study was performed on humans to investigate the physiological strain of wearing protective clothing for shielding electromagnetic waves and to compare control clothing that are currently on the market and new clothing that are developed for improving thermal comfort and material weight. Experiments were conducted in a climatic chamber of $28.8{\pm}0.6^{\circ}C$, $37{\pm}5%$RH under three differed experimental clothing conditions: None, Control, New. The results were as follows. Mean skin temperature and rectal temperature in New were significantly lower than that in None and Control (p<.05). The temperature and humidity inside clothing were lower in None (p<.05). Total weight loss was lower in New. Thermal sensation and thermal comfort were less hot and more comfortable in New than those in Control. It was concluded that wearing the protective clothing for shielding electromagnetic waves affects physiological responses such as distribution of body temperature, sweat rate, etc.

낙상은 노인에서 중요한 건강문제와 직결된다. 노인의 활동력 저하와 노화로 인한 생리학적 변화는 균형과 기능적 가동성 감소를 초래하고 낙상의 주요 요인이 된다. 노년기의 신체활동은 근력유지뿐만 아니라 균형감각 같은 신경계의 기능유지를 위해서도 필요하다. 노화 되어감에 따라 활동이 줄어들고 대근의 활동보다는 소근의 활동을 중심으로 소일하는 경우가 대부분이다. 따라서 신체의 운동범위가 좁아짐에 따라 활동할 때 신체균형감각이 둔화되어 낙상을 일으키게 되고 심각한 사회적 문제를 초래하게 된다. 그러므로 노인의 낙상방지와 생활의 질적 향상을 위해 적당한 강도의 운동과 균형수행력을 향상시키는 훈련이 필요하다.

Purpose: In case of facial injury, a canalicular injury is common. Many methods and materials have been used for reconstruction of lacrimal canaliculi. Silicone tube is the most widely used material, generally with pigtail probe or stainless steel probe. But it has still many problems. The authors guess that reconstruction using Mini $Monoka^{(R)}$ will reduce those problems and will be more successful. Methods: From July, 2003 to November, 2006 in 24 patients with canalicular injury, 11 cases were recon- structed with former silicone tube and 13 cases were treated with Mini $Monoka^{(R)}$. Results: The mean follow-up period was 3 months. The results of reconstruction were classified into three groups(Normal, Fair, Poor). In 13 cases with Mini $Monoka^{(R)}$ stent, 10 cases were normal, 3 were fair, and no poor cases. But in 11 cases with bicanaliculus silicone stent, 6 cases were normal, 3 were fair, and 2 were poor. Conclusion: Compared with bicanaliculus silicone stent, Mini $Monoka^{(R)}$ stent is fixed well, has no aesthetic problems, makes less foreign body sensation. And the results were successful.

This investigates the type of pants preferred by Korean men in their 20s through a subjective wear test. Six types of men's pants were developed as experimental garments. The male subjects were university students between the ages of 20 and 24. Subjective wear sensations of the experimental pants were rated using seven Likert scales. A 7-point Likert-type scale was used for the evaluation, with 7 indicating the best fit. As a result, a basic men's sloper for lower body clothing was developed based on SizeKorea 2004 anthropometric measurements surveyed between 2003 and 2004. A basic pattern (A) was manipulated to tight-fit pants (E) and loose-fit pants (D, L, M, and N) by considering the ease at hip level and the style. Among the six pants, pants D and L (4cm ease at hip level) were found to be superior to others in terms of comfort, fitting, and crotch depth. With regard to ease and comfort of the crotch part, pants E and A (0cm ease at hip level) were found to be the least preferred.
