The need for rapid diagnosis and treatment of life-threatening thoracic and intra-abdominal injury result in controversy over the appropriate triage of unconscious blunt trauma patients. To aid in early decisions for these patients, a prospective analysis of 98 patients with glasgow coma scale(GCS) scores≤8 was undertaken. Although intra-thoracic and intra-abdominal injuries were frequently identified based on systolic blood ressure, the use of clinical signs alone resulted in more missed injuries than did using the emergency ultrasonography. In normotensive patients(n=34), intra-thoracic injuries was identified in one patient(2.9%), and intra-abdominal injuries were in 7 patients(20.6%). In shock(systolic blood pressure<90mmHg) Pa-tients(n=64), thoracic injuries and intra-abdominal injuries were diagnosed in 8(12.5%) and 27 patients(42.3%), thoracic and abdominal combined injuries were identified in 11 patients(17.2%). The sensitivity, specificity, and accuracy of emergency ultrasonography were 96.3%, 91.7%, 94.9%. This study suggests that all unconscious trauma patients undergo immediate emergency ultrasonography to prevent missing life-threatening injuries.

This article is an abstract of the prize-winner master plan for Wolmee Park in Incheon, Korea. The main theme of the park is the revival of the Korean traditional garden style. The park provides a place for citizens to understand and experience Korean traditional garden styles by emphasizing Koreas traditional images and feelings. In addition, cultural traditions are harmonized with modern characteristics of the park. The plan includes restoring Wolmee-haenggung(a temporary palace used to be in Wolmee Island) to hold its traditional meaning as garden and plate of the Wolmee Island. Main design ideas are summarized below. First, the conceptual meaning of jeong-won(庭園, garden) is represented separately: jeong(庭) and won(園). Jeong(庭) is a man-made place and reappeared as tangible objects with traditional forms. In contrast, won(園) with the concept of wonrim(園林), the universal principle of Korean traditional garden style, which focuses on the harmony between human and nature, is symbolically represented as wolmeegugok(月尾九曲, nine beautiful landscapes along the river). Second, to deliver the meanings of the place, various historical and cultural elements of Wolmee Island are metaphorically added to the traditional garden frameworks. And third, the plan basically orients to preserve the ecologically healthy natural environment of Mt. Wolmee. The park will contribute for Incheon citizens as well as people nearby by providing healthy environment and various recreational activities.

As human become aged, he become color weak due to yellowed eye sight. The 87% of information for human behavioral decisions are visually perceived. Therefore, the color weakness will affect his behaviors in many ways. Most of previous research regarding color planning for the aged people focuses on discovering their preferred colors and reflecting the colors on facility color planning. But these research failed to identify confused range of color cognitions due to the color weakness of the aged. In this research, targeting the aged in multi-purpose senior centers, we analyze their color distinctions and confusions using computer graphic tools. Our research discovers several important points. First, there are differences in color cognitions between the young facility designers/staffs and the aged facility residents. Second, these differences lead to the differences in the abilities of spatial cognitions between the young and the aged. Third, the difference in the spatial distinctions if mainly caused not by color itself but by color adjacencies. Based upon these findings, we propose that color planning of facilities for the aged be made not from the view of the designers but from the view of the aged, considering yellowed eye sight of the aged.

The purpose in this study is to develope of high strength and corrosion reistant Mg-Zn system alloys by controlling microstructures and by adding of Cu elements. To produce optimum tesile strength,it is imperative to obtain effective grain refinment during casting. Optimal condition for grain size refining effect was obtained at the minmum composotion of 2wt% Cu or 1.5wt%So addition to Mg-6wt%Zn alloy.Age hardening behavior was experimented at the optimal compositions of the Mg-6wt%Zn, Mg-6wt%Zn-2wt%Cu and Mg-6wt%Zn-1.5wt%Si. The hardeness increment due to age hardening was at the Mg-Zn-Si alloy system. The improvement of corrosion resistanece by the addition with Cu is related to and increasing Zn/Cu ration in the intermatallic particles in the Mg-Zn system.Further improvements obtained by T6 treatment are related to the properties of the Mg-Zn phase,whih acts as a corrosion barrier by precipitating along the grainboundaries.Filiform corrosion observed soon after pit initiation and cellular form of pit propagation later in chloride media are explained in terms of solid solution matrix structure and the properties of air formed oxide.The information obtained from the fundamental research work is utilized in suggesting ways of improving the corrosion resistance of commercial AZ91.

The Evaluation of blunt abdominal trauma is clinically challenging. Abdominal computed to-mography(CT) and diagnostic peritoneal lavage(DPL) has become primary diagnostic modali-ty in advanced trauma life support(ATLS). But DPL is invasive study with potential for the patients. Monitoring and resuscitation are usually suboptimal during there examinations. We examined the efficacy and role of emergency ultrasonographic(US) studies in the initial abdominal evaluation of blunt trauma patients. A prospective study was carried out on 101 blunt trauma patients from 1994, June to September. 101 patients underwent real-time US ex-amination of the chest and abdomen. Indication for emergency US included the cases of shock (systolic blood pressure<90mmHg) or tachycardia (pulse rate/min.>100) in blunt trauma pa-tients. US showed a sensitivity of 96.2%, specificity 98%, accuracy 97% in regard to indica-tion for surgery in case of blunt abdominal or thoracic trauma. US saves time, and it can be performed during the emergency care in the emergency department. US showes high sensitivity and specificty, and is the method of first choice in the evaluation of blunt trauma.

Background : Alteration in plasma lipid levels during malaria attacks was studied to evaluate the diagnstic values in vivax malaria. Methods : The plasma levels of total cholesterol, triglycerides, HDL-cholesterol (HDL-c), and LDL-cholesterol (LDL-c) were analyzed and compared in 32 patients with vivax malaria at presentation, in 10 patients after 17-days of treatment with anti-malaria drug, and in 40 control individuals. Interrelation of lipid profile with other parameters including parasitemia level, platelet count, hemoglobin and WBC counts were analysed. Results : In patients with malaria, serum total cholesterol, triglycerides, HDL-c and LDL-c concentrations were significantly lower than those of control subjects. None of lipid profile showed any correlation with the parasitemia level. After treatment, HDL-c was significantly elevated. Conclusion : These results suggest that lipid profile, especially decreased of HDL-c, may be a valuable information in the diagnosis of the malaria. (Korean J Infect Dis 33:58∼61, 2001)

Objectives : This study was designed to investigate the differences of effects in smoking cessation after acupuncture treatment and we hypothesized that the discrepancies might be caused by individual genetic differences. Methods : Acupuncture treatment was given to the subjects three times a week for the 231 healthy male Korean smokers without personal or familial history of psychiatric or neurological illness. We evaluated for differentiate responder and non-responder who showed more than 50% decrease in the cigarette consumption or the desire for smoking were regarded as responder, and less than 25% decrease in the cigarette consumption or the desire for smoking were regarded as non-responder, respectively. Allele and genotype frequencies of the Taq1 A polymorphism of dopamine D2 receptor (DRD2) gene were compared in 231male smokers. Chai-square analyses were performed to test for an interactive effect between the DRD2 Taq1 A allele. Results : The allele frequencies and genotype distributions of DRD2 gene among the smokers (n = 231) showed significant the differences in their genotype distributions. The responder and non-responder showed the difference in genotype distribution with a prevalence of A1 allele. A slightly positive association of DRD2 Taq1 A1 genotypes with smoking was observed. Conclusions : This experiment results indicate that the present of DRD2 allele genotype showing significant difference in the genotype distributions between responders and non-responders could be explained by the difference in the genetic effect of DRD2 A1 allele.

Objectives : The purpose of this study is to review research papers published by Korean research groups on biophoton of human beings based on experiment subject and methodology. Methods : In order to review human biophoton research executed in Korea, all the papers published in Korean and international journals by Korean research groups were selected. Several key foreign papers were also reviewed for clarification of this study. Based on experiment subjects, experiment methodology, and interpretation of experiment results were analyzed. On each experiment, its original interpretation was directly quoted. Issues on the experiment methodology and interpretation were expressed at the end of each subject. Results and Conclusions : We found that experiments on human biophoton were compelling. However it seemed that mom experiments, especially on their sample sizes, ate needed to demonstrate its clinical application. Interpretations based on Korean traditional medicine also need to be elaborated more. In order to do accomplish clinical application of biophoton, interdisciplinary works are required. Some suggestions on biophoton experiments were made.
