The presence of epicanthal folds in Asian eyelids is one of their unique features, in combination with the lack of supratarsal folds. Western culture has influenced many people to prefer to eliminate the prominent epicanthal fold. A number of surgical techniques have been suggested for their correction. However, difficulty with design, excessive and prominent scarring of medial canthal and nasal area, recurrence, and rigidity of application are potential problems associated with many procedures. This paper describes a epicanthoplasty with three-dimensional Z-plasty. Through epicanthal fold incision, the medial canthal tendon is medially advanced and sutured to the periosteum of nasal bone. After the transposition of the flaps, trimming of the flap is usually required. Three-dimensional Z-plasty creates the attractive eyes. From March, 1995 to March, 1997, the technique was applied to 37 patients with epicanthal fold and was performed with or without double-fold operation. There were 34 females and 3 males with ages ranging from 17 to 30 years. Through 2 years follow-up, this technique has delivered esthetically good results with minimal postoperative scar and could made the reduction of ICD from 40 ± 2.13 mm to 34 ± 1.98 mm. The advantages of epicanthoplasty procedure using three-dimensional Z-plasty(Yoon's method) are as follows; 1) simple in design 2)minimal postoperative scar in the medial canthal area 3) versatile in its application 4) no recurrence 5) no hypertrophic scar 6) preserving ethnic identity.

This study was accomplished to analysis and survey on the experimental and practical science education of high school in korea for the consecutive study of the an analysis and survey on the experimental and practical science education of middle school in korea(Lee, Yoon-Jong et al., 1997). The status of facilities, management for the experiment, practices, teaching methods in high schools have been investigated. The present status and reasonable management of the high school science education have been grasped from the questionaires. To do this 165 high school science teachers, 1977 students and 80 principals of high schools in Korea are administered questionaires of Science Education Research Institute of Kyungpook National University(1997). The results of this study are as follows : The reasonable management for experiments and practices of science education were scanty in the high school around the urban and rural school owing to the shortage of facilities and equipments, crowded class, excessive class works for teacher, excessive contents of present textbooks and insufficiency of the administrative supports etc. The current teaching method of high school science has emphasized knowledge. This fact does not satisfy the objective of learning due to lack of the teaching method. Desirable directions for the improvement of present status of high school science education were proposed in this paper.

Tetrodotoxin is a neurotoxin produced by about 90 species of puffer fish and causes paralysis of central nervous system and peripheral nerves by blocking the movement of all monovalent cation. Ingestion of tetrodotoxin produces clinical manifestations such as paresthesias(within 10-45 min), vomiting, lightheadedness, salivation, muscle twitching, dysphagia, difficulty in speaking, convulsion and death that expressed by cardiopulmonary arrest with loss of brain stem reflex sometimes. Tetrodotoxin prevents or delays ischemia induced neuronal death by way of following 3 mechanisms. Firstly, it reduces the energy demand of the brain tissues. Secondly, it delays or even prevents anoxic depolarization. Finally, it deminishes ischemia induced cell swelling and cerebral edema. We report a case of puffer fish poisoning which presented with cardiopulmonary arrest and loss of brain stem reflex, but completely recovered by aggressive cardiopulmonary resuscitation.

To detemine seasonal fluctuations in abundance and speices composition, polychaete samples were collected by Van Veen grab form March to November 2003 in Kangjin Bay. A total of 25,119.3 ind./㎡ polycaete were sampled and identified into 48 species. 25 families and 10 orders. Of the 10 orders. Phllodocida, Spionida, Eunicida and Sabellida accounted for approximately 79.9% of the polychaete fauna in this area. Phyllodocida, Nereidae, Nephtyidae ans Spionidae were dominant representing every moment 4 species. Of 48 species identified Neanthes japonica, Prionospio pinnate, Cirratulus cirratus and Palola siciliensis for 54.0% individuals collected. Season succession of dominant species was evident in study area: Neanthes japonica, Prionospio pinnata. Cirratulus cirratus. Nephtys oligobranchia in March, Neanthes japonica, Lumbrineris japonica. Cirratulus cirratus, Prionospio pinnata in May, Ncanthes japonica, Cirratulus cirratus, Lumbrineris nippnica. Lumbrineris japonica in August and Neanthes japonica, Prionospio pinnata, Laonice cirrata, Palola siciliensis in November, respectively. The diversity index was the highest value in March(H'=3.0059) and the lowest value in May(H'=2.7305). The eveness index was the highest in August(J=0.9184) and lowest in May(J=0.8524). The dominance index was the highest in May(D=0.3843) and the lowest in March(D=0.2275).

A 14-year-old male pomeranian was present with swollen left ear. The swelling occurred from base to apex of pinna. Otitis externa persisted for two years. Hematological and serum biochemistry values were not remarkable. The surgery treatment was the most appropriate method among indwelling drain, surgical, and steroid treatment in the aural hematoma because the dog was very sensitive to touching pinna and the size of aural hematoma. Longitudinal incision was applied after general anesthesia. Cefovecin was injected to prevent secondary infection. The outcome of surgery was good. There was no evidence of recurrence for one year.

The cellulase components were partially purified from the culture filtrate of the alkalophilic bacterium Pseudomonas sp. AC-711 and its enzymatic properties were characterized. The specific activity of the purified major enzyme component was 3.5 units/mg protein as carboxymethyl cellulase and the yield was 23% of the total activity of the culture broth. The molecular weight of the component was 46,000 and the Km and Vmax on CMC were determined as 15.4 mg mL^-1 and 4.17 μmoles mL^-1 min^-1, respectively. The enzyme was stable at the temperatures below 60℃ and at the pH range of 4.0~11.0, and the optimal temperature and pH were 60℃ and pH 8.0, respectively. The enzyme activity was not significantly affected by the common surfactants (concentration: 0.05%) such as α-olefin sulfonate, linear alkylbenzene sulfonate, sodium dodecyl sulfonate, hexadecyltrimethylammonium bromide and Tween 80. The enzyme was activated by the metal ions such as Ca^2+, Cu^2_, Co^2+, whereas inhibited by Hg^2+ and Zn^2+. The enzyme exhibited relatively high activity toward amorphous CMC as compared with crystalline substrates such as filter paper and avicel.
