The comparison of demand and supply is needed for efficient ecosystem services planning. However, the gap between them cannot be analyzed as existing studies mainly dealt with only the supply of ecosystem services. This study compares the demand and supply of ecosystem services in Shiheung using environmental complaints and urban planning by semantic network analysis. As a result, 'air' and 'water' quality are magnified in demand, 'energy' and 'water' are crucial in supply. This result presents that citizen ask for the improvement of air quality in regulation services, although local government has plans for energy support in provisioning services. Periodic ecosystem services demand and supply monitoring will be the base of effective ecosystem services planning, which reduce insufficiency and surplus.

현재 지적분야는 기존 종이도면관리가 아닌 전산화된 파일관리체계로의 전환, 지적측량시장의 개방, 지적분야의 해외 진출 등 많은 변화를 겪고 있다. 이러한 환경의 변화는 측량의 정확도 향상, 효율화된 관리체계, 지적측량의 경쟁력 강화 등 많은 이점을 가져다주고 있다. 그러나 선진화된 지적관리체계로의 전환은 과거 보다 상대적으로 지적정보 및 기술이 유출될 수 있는 가능성을 높이고 있다. 본 연구에서는 지적기술의 무분별한 유출에 대비하고자 현행 지적분야의 환경변화에 대한 내용을 검토 고찰하고, 이를 토대로 하여 지적기술의 유출방지 및 보호방안을 제시하고자 하였다. At present, the cadastral field, with the conversion into digital cadastral map management system, not the existing cadastral map management system, has gone through a lot of changes, such as the market opening of cadastral surveying and overseas launching of a cadastral field. Such an environmental change has brought on a lot of advantages, such as improvement in accuracy of surveying, efficient management system, and reinforcement of competitive power in cadastral surveying. However, the conversion into the advanced cadastral management system serves to relatively heightening the possibility of outflow of cadastral information and its technology in comparison with in the past. This research, with the aim to cope with indiscriminate outflow of cadastral technology, is aimed at suggesting the plan for the prevention of outflow of cadastral technique and its protection after examining and considering the contents of environmental changes in the currently going cadastral field.

Cholesterol granulomas are unusual, expansile benign lesions, which may produce symptoms from localized mass effect. It can develop in any portion of air cells within the temporal bone as a result of a lack of aeration and inadequate drainage, especially in the middle ear cavity followed by the mastoid process and the petrous apex. But huge cholesterol granulomas with extensive temporal bone destruction and intracranial extension are rarely reported. Recently we experienced a case of huge cholesterol granuloma with intracranial extension misdiagnosed as a intracranial tumor, such as schwannoma or meningioma in a 52-year-old female. After tumor removal, destroyed tegmen tympani was reconstructed with artificial dural materials and plates. We reviewed this case with relevant publishings in medical literature.

The purpose of this study was to analyze water words written by college students in order to investigate their cognition by using ‘contents of water education for sustainable development’. For this study, researchers applied qualitative analysis methods such as a mind map and a water word association test, as well as quantitative analysis methods including a water common sense quiz and a survey of water cognition. The results of this study were as follows; First, college students were rarely interested in water, since the score of a water common sense quiz was quite low; water cognition that college students felt in their daily life was also deficient. Second, college student data shows that while they had specific water cognition, they did not have integrated view of water. Therefore, the study on water cognition of balanced views related to water should be carried out through developing and appling a interdisciplinary subject.

Purpose: There are no reports on amusement-park-related injuries in Korea. Thus, the objective of this study was to describe traumatic injury patterns that occurring in an amusement park. Methods: The medical records of an infirmary were retrospectively reviewed. From January 1, 2008, to December 31 2008, patients who were transferred to the nearest emergency departments of hospitals for the purpose of further test and treatment were enrolled. Demographics, injury types and involved parts of the body were analyzed. Results: A total of 3,608 patients visited an infirmary for traumatic injury and about two-thirds had soft tissue injuries. Of those, 191 patients (5.3%) were transferred to the emergency department of a hospital. Of the patients who were transferred to a hospital, laceration and contusion were the responsible injuries for about half. Laceration was the most common injury in pediatric patients, and a sprain or a strain was the most common in adult patients. The most commonly injured parts of the body were the extremities in adult patients. However, in pediatric patients, injuries of the head, face and neck were similar to injuries of the extremities. Conclusion: Soft tissue injury was the most common amusement-park-related injury. Laceration was the most common reason to transfer a patient to a hospital. There were differences in injury type and injured part of the body between adult and pediatric patients. (J Korean Soc Traumatol 2009;22:103-107)
