Purpose: Gracilis muscle free flap transplantation is chosen in the medium sized soft tissue defect and bone exposure from trauma and chronic osteomyelitis in the lower extremity. We set a study to search for gracilis free flaps to know whether symptoms were cured or recurred in patients that have passed over 10 years from flap transplantation. Materials and Methods: From August 1995 through September 2010, we have performed 28 cases of gracilis muscle free flap in the lower extremities. Ever since no case visited to demand any discomfort, breakdown or recurrence in the flap site on outpatient basis. We made a telephone call to patients or relatives documented in the medical record and only 2 cases visited outpatient department and 9 cases postponed the visit who satisfied with the final result but 17 cases had wrong telephone numbers. Causes, area of lower extremity, recipient vessels in the lower extremity, condition of the donor thigh and overall satisfaction of the flap transplantation in activities of daily living were investigated and written down in the medical record. Results: 11 cases were reviewed after average postoperative 13.7 years. Gracilis muscle flaps were not break down at the recipient site in all cases. The wound of donor thigh wound healed good and overall activities of daily living was satisfied in all cases. Conclusion: Gracilis muscle flaps which had performed and followed up average 13.7 years revealed confident in the medium sized soft tissue defect and bone exposure from trauma and chronic osteomyelitis in the lower extremity.

Objectives: This study investigated patients with oral and maxillofacial lacerations who visited the emergency room over a three-year period in an effort to determine the optimal treatment for these injuries. Materials and Methods: This study examined 1,742 patients with oral and maxillofacial lacerations with 2,014 different laceration locations who visited the emergency room of Pusan National University Hospital (Busan, Korea) over three years, from January 2011 to December 2013. Patients were classified by sex, age, visit day, cause of injury, injury site, and the presence or absence of soft tissue and tooth injuries. Results: The male to female ratio was 2.50:1. Patients under 10 years old were seen most frequently. Most emergency room visits were on weekends. Among intra-oral lacerations, the lip area was the most vulnerable site; among extra-oral lacerations, the chin area was most frequently injured. The most frequent etiology was a slip down. Most lacerations occurred without bone fracture or tooth damage. Conclusion: Laceration may differ in large part as compared with the fracture. Therefore, it is necessary to continue collecting data on oral and maxillofacial lacerations to establish optimal emergency room diagnosis and treatment strategies.

Educational web sites are proliferating at an astonishing rate, however many of those web sites are of poor or unknown quality. Educators are in need of instruments to assist in evaluating educational web sites for authenticity, applicability, authorship, bias, and usability, etc. The ability to critically evaluate educational content form numerous web sites is an important skill in this information age. In this paper, indicators of educational web site quality have been identified from literature review and our own research, and classified within 8 categories. To test the relative contribution of each indicator to the satisfaction level from using educational web sites, a questionnaire survey was administered. Subjects were asked to visit the educational web site of his or her choice and rate the quality level of each indicator. 255 completed questionnaires were turned in for analysis. Cronbach's Alpha test and factor analysis were applied to test the reliability and validity of the data. Stepwise regression analysis was applied to test the relationship between the satisfaction level and 14 independent factors. Implications from the statistical analysis as well as the guidelines for evaluating educational web sites were provided.

This study is limited to epidermoid carcinoma arising in the larynx. The 623 patients in this series comprised 1.6% of all malignant neoplasms seen during the 20-year period .from 1965 to 1984 ; it comprised 13.2% of all cancers of the head and neck registered during this period. The male: female ratio was 11:1, and the highest incidence was in the fifth decade of life. Analysis by anatomical site revealed that 51.7% were supraglottic, 36.1% glottic, and 6.8% subglottic in oriain. One-hundred eighty-nine(79%) were clinically Stage III or Stage IV lesions at the time of the first visit. Of the total of 263 cases, 113 refused treatment, 4 definite radiation for $T_1$. lesion,21 underwent palliative therapy only, and 125 underwent surgical management with intent to cure. This surgical category included 53 patients who had surgical treatment only and 72 who underwent combined therapy(preoperative radiation, postoperative radiation, or inductive chemotherapy followed by surgery and postoperative radiation). The surgical management varied from partial laryngectomy to widefield laryngectomy and ipsilateral neck dissection. In 14.4% pathologically positive node or nodes were found in the clinically negative contralateral neck nedes. Such contralateral spread was most common in supraglottic site of origin(222%). Combined modality of management was compared to single therapy. Although results at three years showed no difference in determinate disease-free survival between patients treated by surgery only and those treated by surgery followed by postoperative radiation therapy at 5 years a statistically significant difference emerged, only 36% of those receiving surgery alone surviving as compared to 65.4% in the surgery with radiation group.

Continuous development of Personal Computer(PC) combined with the decrease of price and the expansion of operating system in PC like Windows 95, and Windows N/T makes it possible for the user to consider PC-bas-ed Automated Happing/Facilities Management (AM/FM) system. Therefore, the purpose of this study is to establish a PC-based data automation system of pipe infrastructures-water, sewer, and drainage-and road in Korea Land Corporation. In order to achieve this goal, relevant literature survey was done first. Secondly, the study site was determined by discussion with Korea Land Institute. Thirdly, PC-based CAD software for AM/FM in the world market were surveyed, and AutoCAD Map was selected because KLC had been using hundreds of AutoCAD copies already. After that user needs assessment was done to visit on-site office, local branch office, and the corresponding city office for the system design and database design. After the graphic data were digitized and the attribute data were entered into the batabase, the data automation system was established, and tested for application. Finally, the guidelines and problems for PC-based data automation in AM/FM was discussed.

Mt. Apsan is well known to be one of the most popular tourist sites around Daegu. Annually, more than 16 million persons visit Mt. Apsan. Although, in the mountain there are varieties of geomorphic and geological resources, there has been less concern to utilize the resources for geo-tourism. For example, there are about 10 valleys within Mt. Apsan and various landforms are scattered around the valleys. In this context, this study, based on field surveys centering around Gosangol valley, Anjiranggol valley and Dalbigol valley, focuses on exploring ways towards developing Mt. Apsan as an example geo-tourist site. The main findings are as follows: 1) The main landforms of Mt. Apsan include river cliff, cavern, free face, mud crack, ripple mark, fold, sheeting joint, talus, alluvial fan, pot hole, fault line, gnamma, columnar joint and metamorphic rock. 2) The guide notes on the landforms are developed. 3) In order to raise a learning effect of visitors on geomorphic resources, 9 nature trails are designed according to valleys and the length of visitor's stay.

This study intends to analyze the characteristics of imageability elements of the tourism space using the spatial cognitive mapping method. For this purpose, this study selects Nami Island as a study site and collects spatial cognitive maps or sketches of the study area focused on tourists in their 20s and 30s after they visit the site. The results of frequency analysis on imageability elements of Nami Island show that paths, landmarks, and edges are more frequently cognized to tourists in their 20s and 30s than districts and nodes. This study determines a new imageability element of the tourism space, "moving objects," such as or bikes or animals. Tourism planners or landscape designers can consider these useful imageability elements as important planning factors in order to improve and clarify the images of tourism spaces.
