The many previous publications have shown the advantages of written discharge instruction over verbal discharge instruction on the basis of comparing the functional illiteracy among emergency department patients. Therefore, authors have conducted a study on the efficacy of written discharge instruction over the verbal discharge instruction of two groups: minor laceration and sprain patients. For the purpose of this study, minor laceration is defined as less than 3 ㎝ laceration on the face or head, or less than 5 ㎝ laceration on extremities. And simple sprains were limited to the extremities. A total of 416 patients who visited Yong Dong Severance Hospital Emergency Care Center were the subject of this study during the period of 2 months from Feb. 1. to Mar. 31. 1996. The study was done prospectively, and patients who entered this study were randomly selected. Simple discharge instruction were made prior to the study and patients were given or verbally told the one of two instruction sets by the emergency medicine resident. After reading or hearing the instructions, each patient was asked to answer four specific questions about them. Statistical significance was examined by t-test and p value of 0.05 or less was considered statistically significant. Mean age for verbal and written instructed group were 26.2 and 25.6 years old. There were 262 and 154 patients in verbal and written instructed group, and the mean score was 2.24±1.20 and 3.42±0.52, respectively. The type of injury was divided into laceration and sprain. Laceration group showed mean score of 2.15±1.23, 3.32±0.51, and sprain group of 2.34±1.16, 3.59±0.50 in verbal and written instruction group, respectively. For the patient younger than 13 years old, discharge instruction was given or described to a guardian. Age less than 13 years old group showed mean score of 2.75±1.11, 3.31±0.48 and more than 13 years old group of 2.10±0.19, 3.34±0.53 in verbal and written instruction group, respectively. The result showed statistical significance between verbal and written instruction group of type of injury and age difference. For the future, simplified written discharge instruction may help and improve the patient`s understanding of the proper management of injury.

As central cities of the provinces north of Gyongsang, Mungkyeong, Andong, Yeongju have to set up a strategic plan of attracting more international and domestic tourists for development of central districts broadly. In particular, Mungyeong city puts spurs to develop after foundation of Mungyeong Tourism and Leisure Town Inc., which the Ministry of Commerce, Industry and Energy, Kangwon land, Mungyeong city joint-found on April 2003. All citizens put their effort on developing the Mungyeong Tourism and Leisure Town Inc., which is invested of national (government) and private expenditure about 11hundred million won. There are several alternative plans that enabled balance-development of promoting tourism locality. However, secure of investment capital is more important in tourist attractions-article connection. The stable secure of financial support for tourism development is primarily based on local economic activity. Unfortunately, almost all Korea local authorities foundations have radical limitation of promoting to tourism development project, this is mainly due to weak economic situation with fragility in local financial. Therefore, it is significant to get the central government and a megalopolis governments intervention regarding tourism development project. At present, the tendency is toward increasing of participating in private sectors and coming under private management in all kinds of development project. In addition, there found some limitation of promoting relative management only in the public organization, thus it is important to induce active private departments participation. Basically, it is essential to find out key factors of overcoming the difficulties on attracting private sectors investment and their participation. At the same time, there need to seek solution of the difficulties and execute offering the incentives hence attract private investment. According to the results from confidence-analysis and factor-analysis, the infrastructure and the expansion of social indirect capital are urgent through active supporting of a central government, megalopolis government and connection of tourism system. Moreover, it is suggested that there need to promote establishing of effective information-system, and correctness in tourist information, which affect in decision of a tourism policy. Finally, it is vital to promote development of tourist attractions-article connection.

The causes of death of pelvic bone fracture are hemorrhage, associated internal organ injuries, sepsis, and multi-organ failure, among which hemorrhage still remains as the leading cause of death. While previous classification for pelvic bone fracture was focused on orthopedic treatment, Pennel & Sutherland suggested a new classification according to the pelvis AP film took in the emergency room. Since this classification supposedly evaluates hemorrhage from pelvic bone fracture, we are reporting on the efficiency of this classification. Out of all the 150 patients admitted to Yong Dong Severance Hospital Emergency Room from 1992, Jan. through 1994, Dec. due to pelvic bone fracture, 18 people with incomplete medical record and X-ray film excluded from the study. The study was done Cohort method and t-test was used. According to the new classification, the unstable fracture had a much more bleeding amount regardless of the type, and type I stable fracture bled more than all the other stable fracture. These were statistically meaningful. Also, there was no differences in the type of fracture when ISS(Injury Severity Scale), GCS(Glasgow Coma Scale), and associated injury were compared. In conclusion, previous classification was done according to orthopedic treatment and this classification could be done only after pelvis X-ray series and pelvic bone CT was performed. Therefore much more time is consumed, more stress is put upon the patient and no comparisons can be made in performing emergency care. On the other hand, modified Pennel &-Sutherl`s classification can be simply classified in the emergency room by taking pelvis AP film only and the bleeding amount can be measured according to the type. Therefore, this classification can be helpful in performing emergency care.

Objectives: This study is a case report of 2,5-hexanedione induced occupational peripheral polyneuropathy. We also investigated the peripheral nerve function of all workers who had been exposed to 2,5-hexanedione in the same process. Methods: In June, 2006, a 2,5-hexanedione exposed worker complained of both hand numbness. He received neurologic, radiologic, laboratorial and electrophysiologic evaluation, including measurements of workplace environment. Five months after cessation of exposure to 2,5-hexanedione, a follow-up electrophysiologic examination was done. We evaluated the peripheral nerve function of 2,5-hexanedione exposed workers by comparing 13 male 2,5-hexanedione exposed workers who were in same company with the patient and 5 male workers who had not been exposed to 2,5-hexanedione. Results: Under electrophysiologic examination, there were abnormalities in sensory and motor nerve velocity, terminal latency, and F-latency of both median nerve and ulnar nerve. After 5 months, the patient symptoms and the results of follow-up electrophysiologic examinations were improved. Comparing the 2,5-hexanedione exposed group with the unexposed group, the sensory nerve velocity of the median and ulnar nerves in the exposed group was decreased. The motor nerve velocity of the peroneal nerve, and sensory nerve velocity of the median and sural nerves were decreased. Terminal latency of median, ulnar, peroneal, and tibial nerves in the exposed group were increased compared with the unexposed group(<0.05). Conclusions: 2.5-hexandione can induce peripheral polyneuropathy in male workers.
