Background: The management of hepatic injuries has changed dramatically during the past two decade after the technologic breakthroughs in radiologic imaging techniques. Recently, the non-operative management of blunt hepatic trauma has become the standard of care in hemodynamically stable patients. We reviewed our experience of the non-operative management of blunt hepatic trauma. And the purpose of this study was to examine the prognostic factors and indicators affecting the decision for treatment modality of emergent hepatic trauma. Methods: The medical records of 84 patients who were treated for blunt hepatic injury at Masan Samsung Hospital from January 2002 to December 2003. The patients were divided two groups, non-operative(Non-OP) and operative(OP), according to the treatment modality. The two groups were compares for age, sex, mechanism of injury, grade of liver injury scale, combined injury, systolic blood pressure, pulse rate, hemoglobin, hematocrit, WBC count, S-GOT, S-GPT, ALP, transfusion amount during initial 24 hours, amount of infused crystalloid fluid, length of ICU stay, length of ward care, morbidity and mortality. The grade of the liver injury were determined by using the organ injury scale(OSI). Results: Among the 84 patients, 46 cases(54.8%) were managed non-surgically, and 3 cases of Non-OP group were treated by transarterial embolization. Between the two groups, there were significant difference in age, injury grade, combined injury, hemoglobin, hematocrit, initial systolic blood pressure, amount of infused crystalloid fluid, amount of transfusion during the first 24 hours, and length of ICU care, morbidity and mortality.(p<0.05) The overall mortality rate was 8.3%, but 2.2% mortality in the non-operative group. Conclusion: Non-operative management may be considered as a first choice in hemodynamic stable patients with blunt liver trauma. The reliable indicators affecting the treatment modality of blunt hepatic trauma were systolic BP, Hb, Hct, amount of infused crystalloid fluid, amount of transfusion during the first 24 hours, liver injury grade and combined injury. Strict selection of treatment madality and aggresive monitoring with intensive care unit were more important.

Background and Objectives: To determine the anatomic position of the inferior alveolar nerve (IAN) canal in patients with mandibular prognathism using the cone-beam CT (CBCT). Materials and Methods: Fifty rami from 25 patients were evaluated. The images were taken by i-CAT and reconstructed 3-dimensionally using the Simplant 11 program. The linear distances between the IAN canal to the buccal cortex (a, $a^{\dag}$ and $a^{\ddag}$), from the IAN canal to the alveolar crest (b and $b^{\dag}$) and the anterior margin ($b^{\ddag}$) and finally the buccal cortical thickness (c, $c^{\dag}$ and $c^{\ddag}$) were measured at three reference planes (VP, OP and HP). Results: On the left side, the average distance of a, b and c were 7.12, 15.96 and 3.60 mm on the VP plane, respectively. On the OP, the distance of $a^{\dag}$, $b^{\dag}$ and $c^{\dag}$ was 6.11, 8.83 and 2.63 mm. For the HP, the distance of $a^{\ddag}$, $b^{\ddag}$ and $c^{\ddag}$ was 4.84, 10.11 and 2.30 mm. On the right side, the distance of a, b and c, on the VP, was 7.10, 16.13 and 3.42 mm, respectively. On the OP, the distance of $a^{\dag}$, $b^{\dag}$ and $c^{\dag}$ was 4.77, 8.75 and 2.68 mm. On the HP, the distance of $a^{\dag}$, $b^{\dag}$ and $c^{\ddag}$ was 4.55, 9.84 and 2.38 mm. Regarding the difference between genders, the distance in male's was longer than female's on the VP (p=0.019), and was thicker in males than females on the HP (p=0.002). Conclusion: The CBCT data provided accurate information about the location and course of the IAN.

This article describes the dynamic behaviors of a rubber tired gantry crane(RTGC) under typical load conditions which are used in the design of gantry cranes. In order to investigate the dynamic characteristics of an RTGC, we developed a finite element crane model for its huge structure. The finite element model was validated with the modal test results, e.g., natural frequencies and normal modes. And other components of RTGC were converted into detailed 3D CAD models and finally transformed to rigid body models in a dynamic simulation program ADAMS. The load conditions considered in this paper were a normal operating condition(OP1) and container hanging condition with no external loads. As a result, we could find there was large influence of crane's vibration owing to its structural stiffness and deformation. And the vibration of crane could made the movements of RTGC, which occurs crash or malfunction of crane works.

본 논문에서 패션 디자인(fashion design)을 평가하는데 있어서 새로운 방법론적 접근 방식을 제시해 보려하였다. 즉 패션 디자이너의 디자인에 대한 철학을 이해함으로서 패션에 대한 근복적인 면에 대해 보다 나은 이해를 갖도록 하는 접근 방식을 모색하려는 것이다. 본 논문의 분석대상은 디자이너 루디 건라이(Rudi Gernreich : 1922-1985)와 그의 작품들인데, 그의 작품들에 나타나는 급진적인 성향 뒤에 숨어 있는 그의 디자인 철학을 집중적으로 분석함으로써 작품과 철학의 상관관계를 조명하려는 것이 그 주된 목적이다. 기존의 그에 대한 평가는‘파격적 패션’,‘소설 스테이트먼트(Social Statement)’,또는‘시각적 창출’등의 표현으로 극히 피상적인 것이었다. 반면에 그가 어떠한 경로로 이러한 디자인을 구상하게 되었는지 또는 그가 현대의상에 얼마만큼의 영향을 미쳤는지에 대한 연구는 극히 소수에 불과하였다. 본 논문의 초점은 건라이의 패션 디자인을 그가 중요한 가치로 믿고 있었던‘개인적 자유에 대한 추구’의 반영으로써 재 평가해 보려는 것이다. 이것의 입증을 위해서 그의 디자인들을 역사적, 사회적 그리고 미학적인 관점에서 분석하였다. 먼저 그의 디자인 철학을 도출하기 위해 그의 개인적 배경에 대한 상세한 검토를 하였고, 그의 디자인과 관련된 자료와, 현존하는 작품들과 그에 따른 참고문헌들에 대한 분석 조사 작업을 하였다. 이 작업을 통해 필자는 건라이의 작품들을 세 개의 주된 주제들, 즉,‘부분적 누디즘(Partial Nudism)’,‘유니섹스 모드(Unisexs Mode)’, 그리고‘옵 아트 패션(Op-art Fashion)’으로 구분하였다.‘부분적 누디즘(Partial Nudism)’과‘유니섹스 모드(Unisex Mode)’는 60년대 중반에서 70ssu대 초반에 출현한 유스 컬츄어(Youth Culture)에 부합하는 그이 디자인의 반영으로써 성의 혁명, 여성 인권운동과 동성애자 인권 운동과 같은 사회이슈들과 그의 디자인이 갖는 상관관계를 보여주는 것이다.‘옵-아트 패션(Op-art fashion)’은 건라이 디자인의 미학적 요소에 초점을 맞추고 있다. 그의 작품에 나타나는 인체와 옵-아트 원리의 관계를 조명해 보고, 건라이가 옵-아트와의 연계하에 그의 디자인을 어느만큼 예술적으로 승화시켰는지를 보여주고 있다. 각 주체들은 건라이 작품들의 개별적인 분석을 통해 논하였다. 본 논문은 보다 넓은 관점에서의 건라이의 디자인에 대한 재 평가로 결론을 지었다. 이러한 재평가 작업을 통해 패션 디자인계에 미친 그의 공헌의 역사적 중요성을 강조하고 현대 패션에 그의 영향이 계속 미치고 있는 이유를 설명하려 하였다.

We suggested an adjusted OPS and weighted adjusted OPS as indices to explain run productivity of teams using the slugging average and adjusted OBP from Korean professional baseball. First, we defined adjusted OBP by modifying currently used OBP. Next, we defined adjusted OPS as the sum of adjusted OBP and slugging average. We also defined weighted adjusted OPS as the weighted average of adjusted OBP and slugging average. Analysis of the data from all games in the regular seasons from 1982~2013 shows that adjusted OPS better explains runs than OPS. For 25 seasons out of 32 seasons, adjusted OPS explains runs better than OPS. Further, weighted adjusted OPS consisting of adjusted OBP (with weight 60%) and slugging average (with weight 40%) gives the best explanation of run productivity. Weighted adjusted OPS has been found to explain run productivity better than weighted OPS proposed in Kim (2012).

This study reports the clinical use of two sevoflurane-based anesthetic techniques in dogs undergoing craniectomy. Twenty-one animals undergoing elective rostrotentorial or transfrontal craniectomy for brain tumor excision, anesthetized with sevoflurane, were enrolled in this retrospective, observational study. Anesthetic records were allocated to two groups: Sevo-Op (sevoflurane and short acting opioid infusion): 8 dogs and Sevo-Dex (sevoflurane and dexmedetomidine infusion): 13 dogs. Average mean arterial pressure (MAP), heart rate, end-tidal carbon dioxide, end-tidal sevoflurane and intraoperative infusion rates during surgery were calculated. Presence of intra-operative and post-operative bradycardia, tachycardia, hypotension, hypertension, hypothermia, hyperthermia was recorded. Time to endotracheal extubation, intraoperative occurrence of atrioventricular block, postoperative presence of agitation, seizures, use of labetalol and dexmedetomidine infusion were also recorded. Data from the two groups were compared with Fisher's exact test and unpaired t tests with Welch's correction. Odds ratio (OR) and 95% confidence interval (CI) were calculated for categorical variables. Intra-operatively, MAP was lower in Sevo-Op [85 (± 6.54) vs. 97.69 (± 7.8) mmHg, p = 0.0009]. Time to extubation was longer in Sevo-Dex [37.69 (10-70) vs. 19.63 (10-25), p = 0.0033]. No differences were found for the other intra-operative and post-operative variables investigated. Post-operative hypertension and agitation were the most common complications (11 and 12 out of 21 animals, respectively). These results suggest that the infusion of dexmedetomidine provides similar intra-operative conditions and post-operative course to a short acting opioid infusion during sevoflurane anesthesia in dogs undergoing elective rostrotentorial or transfrontal intracranial surgery.

In sports, the proportion of data analysis in team management such as team strategy planning and marketing is increasing. In KBO(Korea Baseball Organization) league, in particular, plans such as recruiting players and fostering players are established to devise team strategies for the next year, such as FA and trade, at the end of a season. For these reasons, it is very important to predict players' performance for the next year. In this study, the target was limited to only the batter and tried to find out how to predict whether the performance of the next year will improve. As a standard record for rising and falling, OPS(On-Base Plus Slugging), which is easy to calculate and has a high relationship with team score, was used. In this study, 40 years of regular season data from 1982 to 2021 were used as data, and 11 machine learning classification models were used as experimental methods. Predicting the rise and fall of OPS, RBF SVM, Neural Net, Gaussian Process, and AdaBoost were more accurate than other classification models, and age did not significantly affect accuracy.
