Background and Objectives : Decannulation failure may result from factors such as inadequate ability 0 clear secretion, mucosal induration, granulation tissue, restenosis, tracheal wall depression and vocal cord palsy. We were to evaluate the effectiveness of surgical treatment on the basis of site and type of stenosis. Materials and Method : A series of 44 cases of decannulation difficulty between 1993 and 1997 were reviewed. The following data were collected on each of these patients : primary disease, indication for tracheostomy, site of stenosis, endoscopic findings of stenosis, surgical techniques used for treatment. Results : Primary diseases were 30 head trauma, 4 neck injury, 10 other diseases. Indication for tracheostomy were 37 prolonged intubation, 4 emergency tracheostomy, 3 laryngeal trauma. Endoscopic findings of stenosis were 24 granulation tissue, 16 laryngotracheal collapse, 4 combined with granulation tissue and collapse. Site of stenosis were 3 glottic, 9 subglottic, 24 stomal, 1 substomal, 7 mixed. 22 of 24 cases were decannulation using endoscopic treatment. Conclusion : The most common cause of failed decannulation was sternal granulation tissue. The most effective treatment of granulation tissue was endoscopic technique.

A defect on the product safety display is defined by a failure to prevent the damage caused by the inappropriate explanation, direction, and caution to warn the users of the related risks. In other words, it lacks the sufficient instructions or caution for proper use and is unable to furnish the possible danger of the product and the instructions to deal with it. The defect is the responsibility of the manufacturers who are supposed to provide the adequate information so as to prevent injuries of the users. However, in order to prove the product safety display defective, there should be a comprehensive consideration in many different ways such as social norms (such as property and expectation of the product), usage form, indication of the expected risk, and awareness of consumer about the harm and possibility of avoidance of danger. The purpose of this research is to propose the content and types of standardized indication of safety in the industrial product by collecting and analyzing domestic safety information.

Objective : To report one case where Subdural Hematoma(SDH) in operation indication was treated by Scalp Acupuncture therapy. Methods : The changes in clinical symptoms of headache, dizziness, nausea, vommitting were described when this patient was treated with scalp acupuncture therapy and with herb medication. Results : Symptoms (headache, dizziness, nausea, vomiting. etc) at admission decayed gradually with Scalp Acupuncture therapy. The patients could walk alone at discharge. Conclusion : Though she had been in op. indication, the patient's health improved by herbmedications of Dodamcheseup($d{\breve{a}}ot{\acute{a}}nchu{\acute{u}}shi$)-Tang etc. and by Scalp Acupuncture therapy.

Spaceborne sparse array radar for ground moving targets indication (GMTI) has outstanding advantage over full array radar for constructing ultra-large aperture. Rapid development of millimeter wave (MMW) technology make it possible for realizing MMW GMTI radar, which is much more sensitive to slow moving ground target. The paper presented the system model of a multi-carrier frequency sparse array MMW radar as well as preliminary simulation results, which showed future application of the system is very promising.

In this paper, a CSSMA/AI MAC protocol in packet CDMA network is presented. The main features of this protocol are the code status sensing and reservation for reducing the packet collision. The base station broadcasts the code status on a frame-by-frame basis just before the beginning of each preamble transmission, and the mobile station transmits a preamble for reserving a code based on the received code status. After having transmitted the preamble, the mobile station listens to the downlink of the selected code and waits the base station reply. If this reply indicates that the code has been correctly acquired, it continues the packet transmission for the rest of the frame. If there are other packets waiting for transmission, the base station broadcasts the status of the code as reserved, and the mobile station transmits a packet on a reserved code for the successive frames.

The rural area has aged and depressed for urban area in Korea. Furthermore, the rural house has deteriorated and is vulnerable to disaster which collapse, fire, landslide, and so on. For this matter, it need to an evaluated system for deteriorated level of rural house. The evaluated system has a repairing method and an estimated cost for rural house to offer native in rural area. This study could draw evaluation factor for deteriorated level of rural house as a basic study for the evaluated system. The evaluation factors is compared the Korean housing performance grade indication system, the Korean green building certification criteria, and the Japanese housing performance indication system. As a result, they could eight types. There are a mothproof, an waterproof, a finishing material, an asbestos cement slate of roofing, a mobility right, an opening and closing of doors and windows, an indoor environment.

This paper presents the automatic music emotion classification on acoustic data. A three-level structure is developed. The low-level extracts the timbre and rhythm features. The middle-level estimates the indication functions that represent the emotion probability of a single analysis unit. The high-level predicts the emotion result based on the indication function values. Experiments are carried out on 695 homogeneous music pieces labeled with four emotions, including pleasant, calm, sad, and excited. Three machine learning methods, GMM, MLP, and SVM, are compared on the high-level. The best result of 90.16% is obtained by MLP method.

In this paper, we propose the localization algorithm for the cooperative behavior of the swarm robots based on WSN (Wireless Sensor Network). The proposed method is as follows: First, we measure positions of the L-bot (Leader robot) and F-bots (Follower robots) by using the APIT (Approximate Point In Triangle) and the RSSI (Received Signal Strength Indication). Second, we measure relative positions of the F-bots against the pre-measured position of the L-bot by using trilateration. Then, to revise a position error caused by noise of the wireless signal, we use the particle filter. Finally, we show the effectiveness and feasibility of the proposed method though some simulations.

An automatic modal identification program is developed for continuous extraction of modal parameters of three cable-supported bridges in Hong Kong which are instrumented with a long-term monitoring system. The program employs the Complex Modal Indication Function (CMIF) algorithm for identifying modal properties from continuous ambient vibration measurements in an on-line manner. By using the LabVIEW graphical programming language, the software realizes the algorithm in Virtual Instrument (VI) style. The applicability and implementation issues of the developed software are demonstrated by using one-year measurement data acquired from 67 channels of accelerometers permanently installed on the cable-stayed Ting Kau Bridge. With the continuously identified results, variability in modal vectors due to varying environmental conditions and measurement errors is observed. Such an observation is very helpful for selection of appropriate measured modal vectors for structural health monitoring use.
