Trauma is well known as a major cause of death and disability in Korea, but we do not have a optimal method to evaluate the trauma patients effectively. The purpose of this study was to predict the prognosis and mortality of the trauma patients and to evaluate the quality of trauma care by TRISS method. A retrospective study of 100 cases of trauma victims who visited to emergency room and was admitted to surgical intensive care unit of Kyungpook University Hospital from January 1994 to December 1995 by TRISS method was made. In this study, we have found out following results. 1. Sex ratio of male to female was 4:1 and the mean age was 44 years. 2. Analysis of injury mechanism showed high incidences of traffic accident(71%), fall down(14%), cultivator(5%), penetrating trauma(3%) in order of frequency. 3. A comparison between survivors and deaths showed difference in TS(14.81±1.31 vs.13.64±1.43), RTS(7.26±0.82 vs. 6.78±10.24 vs. 37.45±11.05), TRISS Ps-1 TS and ISS(0.93±0.11 vs. 0.79±0,15), and TRISS Ps-2 by RTS and ISS(0.89±0.15 vs. 0.73±0.19). 4. By TRISS method, unpredicted outcomes occurred in 11 of 100 with 10 unpredicted deaths and 1 unpredicted survivor by TRISS-1 and unpredicted outcomes occurred in 14 of 100 with 9 unpredicted deaths and 5 unpredicted survivors by TRISS-2. 5. The most common cause of death was chest trauma(36.4%). 6. The Z statics, quantitating the difference in the actual number of deaths and the predicted number of death, using TRISS-1 method was 0.84 and using TRISS-2 method was -0.57. The authors conclude that the real dead patients exceeded the predicted outcome in TRISS-1 and the real dead patients were less than the predicted outcome in TRISS-2, and our patient management as well as application of this method should be analyzed for accurate outcome. In conclusion, TRISS method offers a good approach for predicting the prognosis and mortality of the trauma patient and evaluating trauma care.

Background: To examine the influencing factors on patients' satisfaction in the emergency department(ED) for quality assurance. Methods: Patients who visited to the ED were prospectively investigated from November 1 to December 31, 1997. Authors developed questionnaire to investigate influencing factors on patients' satisfaction. A Chi-square test and LISREL 7.0 were applied for statistical analysis. Results: Patients' satisfaction was significantly related to physical environment variables, accessibility variables, kindness of hospital personnel variables, and patient's trust for doctors variables. In path analysis, willingness for revisit was influenced by patients' satisfation, accessibility, physical environment, patients' trust for doctors in order, and willingness for recommendation was influenced by accessibility, patients' satisfaction, and kindness of hospital personnel in order. Conclusions: The influencing factors on patients' satisfaction are physical environment, accessibility, kindness of hospital personnel, and patient's trust for doctors. Willingness for revisit and willingness for recommendation are influenced by patients' satisfation. In spite of some limitations, the results of this study can be used as a baseline information for exploring the influencing factors on patients' satisfaction. Further comprehensive research efforts should be made on the study of patients' satisfactoin in the ED.

陶磁轉寫用 野生花紋樣開發에 關한 硏究

서경석,윤종금 한국공예학회 2001 조형디자인연구 Vol.4 No.1

Modern society has greatly changed our life styles and especially it resulted in the great changes in tablewares. Ceramic industries have manufactured the decorative products in large quantities using transfer paper, employed designers who take charge of transfer papers, managed transfer paper factory directly and experimented the transfer paper patterns, which resulted in the remarkble development of transfer papers. Although colors and patterns have been diversified and the printing effects have obtained high definition, the changes of demand patterns which have been higher require the research and development of materials of a new pattern design. Therefore our favorite patterns should be selected, changed and recomposed to meet the modern sense and then the transter paper pattern should be developed to suit the Korean image with the change of colors. This study is to make ceramic materials with the motif of wild flowers among Korean images, develop the naive pattern and product by researching the pattern of ceramic materials with Korean wild flowers and seek a new expression method of ceramic.

TALP-35 purified from human term placenta is known to increase microtubule polymerization and stabilize the polymerized microtubule. To examine the effect of TALP-35 on immune system this study was performed. MTT assay was performed to investigate the effect of TALP-35 on the proliferation of RAW264.7 cells. TALP-35 dose dependently suppress the proliferation of RAW264.7 cells at high concentration (above 1 μM) in unstimulated cells, in case of 10 μM TALP-35 treated cells the suppression was 25% but in stimulated cells it was only 15%. Cosedimentation assay was carried out to investigate whether TALP-35 can bind to tubulin of RAW264.7, monocyte/macrophage lineage of mouse, and polymerize it. TALP-35 polymerize the tubulin of RAW264.7 cells and sedimented in dose-dependent manner. To investigate the effect of TALP-35 on the expression of iNOS protein western blotting was performed. The expression level of iNOS was decreased dose dependently in high concentration of TALP-35 treatment. To examine the activity of iNOS, secreted NO was determined by method based on Griess reaction. Interferon-γ and LPS-stimulated production of NO from RAW264.7 cells was decreased dose dependently above 0.1 μM concentration of TALP-35 and 50% is decreased at 10μM of it. This study shows TALP-35 can control cytokine induced-iNOS expression therefore it might control inflammatory diseases.

고온기 고추육묘에 처리한 생장억제제 처리 효과 및 정식 후 생육억제를 회복하기 위하여 GA, 관수, 고온처리 효과에 대한 연구 결과는 다음과 같다. 1.생장억제제 트리아졸계 처리 횟수에 따라 초장 및 주경장은 뚜렷한 차이를 나타냈고 근장도 2회 처리를 함으로 1회 처리를 한 것보다 발달하지 않았다. 2. 왜화된 고추묘의 생육억제 해소에 미치는 영향은 초장 및 주경장의 생장에는 GA처리구가 뚜렷하였으나 다른 처리구는 비슷한 경향이었고 경경은 변화가 없었다. 3. 생육회복을 위한 처리별 생체 및 건물중은 정식 후 30일까지는 변화가 거의 없었으나 그 후 45일까지 급격히 증가하였는데 고온 및 관수처리구에서 뚜렷한 차이를 보였으며 45일 이후에는 모든 처리구에서 비슷한 경향을 보였다. 4. 정식 45일 경 처리구간 엽록소 함량은 GA처리구에서 가장 낮았으며 다른 처리구간에는 비슷했다. This study was carried out to find effects of restoration of hot pepper seedling dwarfed by the treatment of diniconazole by introducing GA₃, Irrigation and high temperature at knight and the results obtained are summarized as follows. The main results of this research are summarized as follows. 1. In the case of plant height and main stem hight treated with the first time and second time diniconazole showed the strongest effect than untreatment. The root length treated with diniconazole the first time effect gradually disappeared than the second time. 2. Sprays of GA₃100ppm to the dwarfed seedlings by diniconazole pretreatment were effective in counteracting the plant height and main stem height growth inhibition caused by diniconazole pretreatment. 3. The fresh and dry weight of pepper seedling were not significantly different untill 30days in planting, but were increased to 45days from 30days in planting. 4. The chlorophyll content were decreased more or less treatment of GA₃ 100ppm after 45days in planting.

거대한 중국이동통신시장에서 경쟁에서 살아남기 위해서는 현재의 중국 이동 통신시장 현황과 중국시장에 진출한 다국적기업의 사업형태, 그리고 중국 소비자들의 Trend를 이해해야 할 것이다. 국내 기업의 중국진출은 다음과 같은 기회와 위험의 요소를 함께 가지고 있다고 할 것이다. 이와 같은 상황을 정확하게 파악하고 다음의 상황을 주시하면서 중국시장에 대한 접근을 시도해야 할 것이다. 첫째, 중국정부의 이동통신정책과 규제에 대한 정확한 이해와 대응이 필요하다. 둘째, 중국현지 사업파트너의 선정에 있어서 기업의 목적을 최대한 성사시킬 수 있는 기업을 선택해야 한다. 셋째, 위험을 최소화하기 위하여 국내기업간 컨소시엄의 구성함으로써 위험은 줄이고 투자수익은 극대화 하는 것이 중국투자에서 성공하는 방법일 것이다. 넷째, 중국로컬기업의 시장경쟁에서 우위를 유지하기 위해서는 이동통신기기 주요부품에 대한 국산화율을 더욱 높여야 할 것이다.

In this paper, we describe about machining error for tool deflection in slot-cutting processes using micro end-mill. In order to determine the compensated tool path, two machining error parameters are defined and modeled using the SEM images. Experiments are carried out to validate the approaches proposed in this paper. In result of, we decrease a machining error in slot-cutting processes for compensated tool path.
