Apple scar skin, one of the most destructive diseases affecting apple, is caused by Apple scar skin viroid (ASSV d). Fruit dappling appeared on several cultivars in Korea and has been distributed to major cultivated areas since 2001. ASSVd was identified from infected fruits by using nucleic acid sequence-based amplification with electrochemiluminescence (NASBA-ECL). NASBA-ECL method was faster and hundredfold more sensitive than reverse transcription-polymerase chain reaction (RT-PCR) for ASSVd detection in apple leaves/ stems. ASSVd was rapidly transmitted to the entire tree in the second year after artificial inoculation. The ASSVd could be transmitted efficiently by using contaminated pruning scissors to both lignified stems (60 to $70\%$) and green shoots (20 to $40\%$) of apple tree and young plants. Dipping of contaminated scissors in $2\%$ sodium hypochlorite solution effectively prevented viroid transmission. In the ASSV d-infected fruits, the viroid was easily detected from fruit skin, seed coat, and embryo. Moreover, embryo and endosperm separately excised from the ASSVd-infected seeds were ASSVd positive in NASBA-ECL assay. Seedlings germinated from ASSVd-positive seeds showed $7.7\%$ infection rate., which indicated that ASSVd is seed-borne.

Muller's muscle-levator aponeurosis advancement procedure was performed to correct mild to moderate congenital blepharoptosis with moderate to good levator function and to correct severe aquired blepharoptosis with poor levator function. Through the blepharoplasty incision, the upper half of the tarsal plate was exposed and the orbital septum was opened to show the levator aponeurosis. The Muller's muscle was dissected from the superior margin of the tarsal plate and from the posteriorly located conjunctiva with sharp scissors. The Muller's muscle and levator aponeurosis were advanced on the anterior surface of the tarsal plate as a composite flap and fixed approximately 3 to 4 mm inferior to the upper edge of the tarsal plate with three horizontal 6-0 nylon mattress sutures. The amount of advancement of the composite flap was controlled by the location of the upper eyelid margin 2 mm below the upper limbus in primary gaze after the first suture in the middle portion of the flap. The excess flap was trimmed off with scissors, but trimming was usually not necessary in cases of mild to moderate ptosis. Nine cases underwent this Muller's muscle-levator aponeurosis advancement procedure from September 2003 to September 2004. Five cases were congenital blepharoptosis with 2-4 mm ptosis and more than 5 mm of levator function, but three of the four acquired ptosis cases had more than 4 mm ptosis with poor levator function. The age of the patients ranged from 7 to 81 years. In operative results, all patients except one traumatic case were within 1 mm of the desired eyelid height in primary gaze. This procedure can provide not only tightening of the Muller's muscle but also advancement and firm fixation of the levator aponeurosis to the tarsal plate, yielding predictable results.

Objectives : Vocal fold augmentation using injectable material is an easy and simple operation. This study is to evaluate the histology of minced and injected autologous auricular cartilage and fat graft in the augmentation of unilateral vocal fold paralysis using a canine model for two years. Study Design : A prospective study with the contralateral side of the larynx used as the control Methods : Twelve dogs were operated. At first, a piece of auricular cartilage was harvested from ear and minced into tiny chips with a scalpel and scissors. And also, a piece of fat tissue was harvested from inguinal area and minced into tiny chips with a scalpel and scissors. The minced cartilage and fat-paste (0.2ml) was injected using a pressure syringe into the paralyzed thyroarytenoid muscle under direct laryngoscopy. Two animals were sacrificed at 3 days, three at 3 weeks. two at 3 months. one at 6 months, one at 12 months, three at 24 months. Each dog underwent laryngectomy and serial coronal sections of paraffin blocks from the posterior part of the vocal fold were made. Result : There was no significant complication perioperatively and during follow-up. There was acute inflammatory findings in the graft at 3 days and 3 weeks. Only a very small proportion of the injected cartilage was absorbed due to the degenerative change and the overall volume was preserved even when the cells died out. The injected cartilage remained in the larynx until 24 months. Conclusion : The autologous cartilage implant using auricular cartilage was the ideal vocal cord augmentative material for the treatment of glottic incompetence.

Corticosterone is known as a biological stress index in many species including birds. Feather corticosterone concentration (FCC) has increasingly been used as a measure for chronic stress status in broiler chickens. As sample preparation is the first step of analytical process, different techniques of feather matrix disruption need to be validated for obtaining better result in analysing corticosterone extraction. The current study was a validation of pulverizing the feather by bead beater (BB) and surgical scissors (SS) processing prior to corticosterone extraction in feather of broiler chickens. The type of feather processing prior to the hormone extraction may alter the final output. Thereby, finding a standard method according to laboratory facilities is pivotal. This study carried out to determine the effects of feather pulverization methods on the extraction amount of corticosterone in broiler chickens. Feathers were sampled from four weeks old Ross 308 broiler chickens (n = 12 birds). All broiler chickens were kept under the same environmental condition and had access to feed and water. Feather samples were assigned to one of the following processing methods 1) using a BB for pulverizing and 2) using a SS for chopping into tiny pieces. Each sample was duplicated into two wells during enzyme immunoassay (EIA) analysis to improve the accuracy of the obtained data. The results showed lower standard errors and constant output of FCC by using the BB method compared with the SS method. Overall comparison of FCC showed a significantly higher (p < 0.001) amount of the FCC in the BB compared with the SS. Overall, using the BB method is recommended over the SS method for feather processing due to the ability to homogenize a large number of samples simultaneously, ease of use and greater extraction of feather corticosterone.

The patient suffered cardiac arrest 8 months before presentation. She has been suffering hoarseness and exertional dyspnea and nocturnal stridor. Upon flexible laryngoscopy, her vocal cords showed no motion and fixed in paramedian position. There was no causal finding on neck CT. EMG showed some muscular activity. Under the suspicion of crico arytenoid fixation, we performed suspension laryngoscopy, and found the arytenoid cartilage was fixed with short and stout scar, which was removed with scissors. Just after surgery she regained her voice and respiration.

Recently, as it is growing concern about Non-Photo-Realistic Rendering, several researchers are studying to simulate conventional artistic expressions such as pen-and-ink, watercolor and impressionism techniques. In this paper, we describe a mosaic technique using color paper tore by hands. We will also try to represent real paper by using random midpoint displacement method (RMD) to express a shape of paper tore by hands without using cutters or scissors. The Perlin's noise function is used to express texture of paper.

This paper applies the fuzzy logic controller to a semiactive seat suspension system in order to obtain the better ride comfort in constraint of specific rattle space. The seat suspension system used for this research is a scissors-type one with the MR (Magnetic Rheological) fluid damper. Since a seat suspension system with a driver can not be exactly modeled, it is effective to control with the fuzzy logic controller. The rule was carefully tuned to effectively reduce the vibration transmitted to a driver. The on-road ride was realized on a hydraulic excitor and the result shows that the fuzzy controller has reduced the vibration of a seat suspension system compared to the continuous skyhook controller.

A cardiac injury is one of the most dramatic and demanding emergencies than may be cared by the surgeon. Four patients who sustained penetrating wound of the heart have been experienced in the Depart-ment of Thoracic Surgery, Kyungpook National University Hospital. They were 3 males and one female. The age was between 21 and 25. All of this series had stab wounds on the heart by instruments of scissors, gimlet, kitchen knife and glass. Injured sites were two cases of right ventricle, one of the right atrium and one of indifinitive with pericardial laceration. Three of these patients have been successfully treated by emergency thoracotomy with 3-0 silk sutures for myocardial penetrating wounds. One of these patients occurred cardiac arrest during surgery and expired, who was in penetrated right ventricular injury through which massive bleeded. The classic clinical description of tamponade, Beck`s triad, seemed to be useful for making diagnosis of the tamponade but not entirely reliable as diagnostic criterion of the tamponade. In the studing of 3 tamponade cases in these series, the triad of Beck was presented in only two cases. Elevated venous pressure was thought to be a valuable diagnostic factor in pericardial tamponade.

In this paper, an improved method of hand detecting and hand gesture recognition is proposed, it can be applied in different illumination condition and complex background. We use Adaptive Skin Threshold (AST) to detect the areas of hand. Then the result of hand detection is used to hand recognition through the improved HMM algorithm. At last, we design a simple program using the result of hand recognition for recognizing "stone, scissors, cloth" these three kinds of hand gesture. Experimental results had proved that the hand and gesture can be detected and recognized with high average recognition rate (92.41%) and better than some other methods such as syntactical analysis, neural based approach by using our approach.
