The freshwater fish fauna of the Sobaeksan National Park was censused during May 1992 to October 1992 at nine sampling stations to establish base line data for national conservation program on the National Park. Twenty seven freshwater fishes included 13 endemic species in Korea belonging to 9 families were collected in this region. Fifteen species were found in Hangang and 17 species were found in Nackdonggang. however common species were only 6 species. Dominant species. of this region were Zacco temminckii. Moroco oxycephalus. Liobagrus andersoni and Odontobutis platycephala. Morphological anomaly was appeared in 11 species include Zacco temminckii. Zacco platypus. Moroco oxycephalus. thus definitive analysis and consideration for natural conservation need to this situation.

Skin cancer, which often occurs as a result of skin exposure to ultraviolet light radiation, usually presents with characteristic abnormal features, such as ulcerative lesions, irregular morphology, bleeding, and excessive growth. Therefore, skin cancer rarely resembles a benign tumor on visual inspection. Nonetheless, squamous cell carcinoma and basal cell carcinoma with nodular or polypoid features can have a similar appearance to that of benign tumors, meaning that they are sometimes misdiagnosed as benign. As benign and malignant tumors have some overlapping features, clinicians sometimes use additional imaging techniques such as ultrasonography to improve the accuracy of the diagnosis because even a malignant tumor that externally resembles a benign tumor generally has internal morphological features characteristic of malignancy, such as invasion and irregular borders. However, these imaging tools also have limitations, and punch or excisional biopsy can be needed if malignancy cannot be completely ruled out. Herein, we report a case of skin malignancy initially misdiagnosed as a benign epidermal cyst based on external visual inspection and ultrasonography.

The differential diagnosis of lesions in buccal area include lipoma, neurofibromas, epidermoid cyst, salivary ducts calculus, hemangioma, lymphadenopathy. Accessory parotid glands is defined as salivary gland tissue adjacent to the parotid duct, but separated from the body of parotid and it may be found in approximately 20% of human parotid glands. The appearance of an accessory parotid tumor is rare, with a reported frequency of 7.7% of all parotid neoplasm. Angiomyoma, which is also termed angioleiomyoma, is a rare solitary subcutaneous tumors arising from the vascular smooth muscle. It often occur in the extremities and is rarely found in buccal area. We present 2 cases of rare tumor in buccal mass and resected surgically without facial nerve palsy.

Purpose: We try to retrospectively analyze the clinical results of the modified Chrisman-Snook procedure for chronic ankle instability. Materials and Methods: From November 1997 to April 2006, thirty-one patients who underwent modified Chrisman-Snook procedure for chronic ankle instability were analyzed. All patients were male and the mean age was 31 years. The follow-up period averaged 48 months. We evaluated the clinical results measured by Hasegawa method. Results: Among them, there were soldiers in 11, socker players in 6, patients who weigh more 80 kg in 5. And there were 9 patients who previously underwent modified Brostrom procedure for chronic ankle instability. The clinical results were rated as excellent in 29, fair in 2 who did not cooperate with postoperative rehabilitation program. There were complications of 2 cases of irritation of the sural nerve and recurrence respectively, 1 case of wound problem. Conclusion: Our results show that the modified Chrisman-Snook procedure is effective treatment method for patients with high-performance athlete/soldier or failed modified Brostrom procedure.

Purpose: The purpose of this study was to examine the relationship between the behavioral responses of children with burns, and anxiety and depression in their parents. Methods: Ninety-three parents of children with burns, ages 4 to 15 years who were admitted to hospital for an acute burn agreed to participate in this study. The Child Behavior Checklist, Beck Anxiety Inventory and Korean Version of Beck Depression Inventory were used for data collection. Results: The mean scores for acute traumatic disorder, post traumatic disorder, anxiety and depression were $9.05{\pm}3.04,\;39.59{\pm}8.75,\;11.89{\pm}11.53$, and $10.16{\pm}8.22$, respectively. There were significant relationships between depression and gender of children, education of parents, and number of family members. Child's behavioral responses were positively correlated with parents' anxiety and depression. Conclusion: The study found that the greater the behavioral responses of the children with burns, the more anxiety and depression experienced by the parents. The results indicate that psychological support must be provided for both the children with burns and their parents in conjunction with treatment of the burns.

Parotid gland plays the most critical role in saliva secretion in the oral cavity. Parotid gland injuries due to facial trauma can cause various complications such as formation of a fistula or sialocele. Thus, such saliva-related complications can interfere with wound healing and increase the risk of infection. Several previous studies have discussed the treatment of fistula or sialocele. Nonetheless, prevention of such complications is of utmost importance. We present a case of parotid gland injury due to trauma to the cheeks that was surgically treated, with early postoperative management involving oral administration of nortriptyline and closed drainage, without complications.

Propose: The purpose of this study was to help families decrease and alleviate the burden on family care-givers taking care of elderly patients. Method: Data was collected by a questionnaire from 100 family members who were registered in the department of home health care nursing at 4 hospitals of H University Medical Center from September 20 to October 25, 2005. The collected data was analyzed using Mean and Standard Deviation, Pearson Correlation Coefficient, t-test and One-Way ANOVA with the Duncan's test, and Stepwise multiple regression. Result: The average burden on family care-givers of elderly patients with chronic diseases was 3.31. The social burden was the highest(M=3.68), the lowest was the emotional burden(M=2.95). In ADL of elderly patients with chronic diseases, all 10 questions showed an average point above 2.50. The dependency level of going up and down the stairs was the highest(M=2.88). Conclusion: This research is necessary for the application of a plan in the social support system in order to reduce the burden on family care-givers who are taking care of elderly patients with a chronic disease.

Part-whole bias in contingent-valuation studies is a possible explanation for non-use contingent-valuation estimates that are insensitive to marginal changes in environmental commodities. To increase the quality of river water, it is tested how much WTP is paid and is tested whether there is a part-whole bias in this contingent studies. An empirical test of the component sensitivity is provided. This test rejects the hypothesis that respondents are insensitive to the scope of the good being valued. WTP estimated in this paper is 5,435.69 won for Hangang model, and 7,182.68 won for 4-river model. And it might be concluded that part-whole bias exists and it is mainly attributed to substitution and net-benefit effects.

Distortion Product Otoacoustic Emissions (DPOAEs) can be measured in the external ear canal two fold: amplitude and latency, but most DPOAE studies deal with amplitude aspects. The purpose of this study was to investigate the latency of the 2f1-f2 DPOAEs in ears with hearing losses and to see if it could be a clinically useful method to distinguish normal from abnormal ears. For this purpose, DPOAE latency were measured as a function of frequency from 1 to 8 kHz in 30 ears with conductive and sensorineural hearing losses (SNHLs). DPOAEs were recorded with Otodynamic Analyzer ILO92. Results showed that the latency decreased as the frequency increased up to 8 kHz. The mean values of DPOAE latency for ears of SNHLs were shorter at all frequencies when they were compared to the mean values of normal ears. The latency in ears of conductive hearing losses was shorter than normal ears at the selective frequencies, as well. The results support the hypothesis that latency values are shorter in pathological ears.

Purpose: The study aimed to evaluate the changes of body temperature and to identify the factors related to changes during surgery in burned patients. Methods: A retrospective study was conducted by reviewing the medical records of 439 adult burned patients who had a surgery under general anesthesia at the Burn Center of a university hospital. Results: After surgery, body temperature of the burned patients declined from $36.6^{\circ}C$ to $35.2^{\circ}C$; 52.2% were hypothermia. There were significant differences in the changes of body temperature according to the participants' characteristics including American society of anesthesiologists physical status, type of burn injury, total burn surface area, range of exposure, operation time, anesthesia time, amount of fluid, blood transfusion, use of tourniquet, and the method of warming therapy. Factors that influence the temperature changes were total burn surface area (${\beta}=0.26$), operation time (${\beta}=0.25$), amount of fluid (0.20), and warming therapy including 'Room temperature setting + Heated circuit + Hot line'(${\beta}=0.09$) and 'Room temperature setting+one of others'(${\beta}=0.08$). Conclusion: Burned patients experienced a decrease of their body temperature during surgery despite of warming therapy. A nursing protocol is needed to provide an appropriate warming therapy based on their characteristics in burned patients.
