Background: Venous thromboembolisms (VTEs) constitute a group of diseases including deep vein thrombosis (DVT) and pulmonary embolism (PE). They regarded as the second leading cause of death in cancer patients and several studies have confirmed that VTEs have a negative impact on survival and recurrent rate in both ovarian and endometrial cancer cases. The incidence of VTEs differs worldwide and depends on several risk factors including race, underlying disease, lifestyle, body weight, BMI and genetic risk factors. There is heterogeneity of DVT rates between Asian and Western countries. This study was conducted in order to evaluate the character and incidence of VTEs in gynecologic oncology patients in King Chulalongkorn Memorial Hospital over a 10 year period. Materials and Methods: A retrospective chart review was performed with VTEs defined as objective diagnosis of acute DVT or PE with typical symptoms and signs. Diagnoses were approved byan internist and/or confirmed with imaging studies. Data from both outpatient and inpatient sessions of the affected cases from January 2004 to December 2013 were extracted. General characteristics of the patients were collected with details of the diseases, types of cancer, stage, date of diagnosis of cancer, operative data, treatment outcome, progression free survival and overall survival. Results: Thirty cases of VTEs were identified in a total 2,316 gynecologic oncology cases. The incidence of symptomatic VTEs in total gynecologic oncology patients in our institution is 1.295%. The incidence of VTEs in ovarian cancer patients in our institution was 5.9%. Duration for VTE detection ranged from 13 months before diagnosis of cancer to 33 months after diagnosis of cancer. Most of the VTE cases were detected in ovarian cancer patients (60%). The most common cell type was adenocarcinoma (moderately to poorly differentiated) which accounted for 26.7% of the cases. The second most common cell type was clear cell carcinoma with 23.3% of the cases. Thirty percent of VTE cases developed before cancer was diagnosed, 20% were diagnosed at the same time as cancer detection and fifty percent developed after cancer was diagnosed. Median disease free survival of the gynecologic oncology patients with VTE was 7.5 months. Median overall survival (OS) was 12 months. Median progession free survivals of DVT and PE groups were 11.5 and 5.5 months, respectively. OS of DVT and PE was 12.0 and 11.5 months respectively. Conclusions: The incidence of VTE in Asian countries is believed to be lower than in European or Western countries. From our retrospective review, the incidence of VTEs in all types of gynecologic oncology was 1.295%, much lower than reported in the West. The reason for the lower incidence may genetic differences. Another factor is that VTE in this review was symptomatic, which is less than asymptomatic VTE. More than half of VTEs in this study developed in ovarian cancer patients. The results are compatible with earlier reports that among gynecologic malignancies, the incidence of VTE is highest in ovarian cancer.

중력 및 자력 탐사자료를 분석하여 제주도의 지지구조를 연구하였다. 부우게 중력이상도에서 섬 중앙의 한라산체에서 뚜렷한 원형의 저이상이 나타나며, 이상값의 차이는 최대 30 mgal 로 나타났다. 지하지질구조 모델링을 위하여 기반암 상부에 위치하는 화산암체를 각주로 나누어 중력자료의 삼차원 심도역산을 실시한 결과, 화산암의 기저면은 한라산 아래로 휘어지며 최대 깊이는 5 km 정도에 이른다. 자력자료로는 항공탐사자료와 육상탐사자료를 함께 이용하였다. 이들로부터 구한 자력이상도는 다소의 차이는 보이나 전체적으로는 중위도 지방에서 지구자기장의 방향으로 자화된 자력이상체로 부터 야기되는 전형적인 이상의 형태를 보인다. 자극변환을 한 이상도를 보면 섬의 주된 자력원은 장축을 따라 발달하는 열곡대와 한라산체로 나타난다. Cordell과 Grauch (1985)의 방법으로 구한 자력원의 경계는 표선리 현무암과 시흥리 현무암과 같은 비교적 최근에 분출된 화산암의 경계와 잘 일치한다. 자력모델링은 심도와 대자율을 두 변수로 취하여 항공탐사자료의 삼차원 역산을 수행하였다. 역산 결과, 높은 대자율을 가지는 화산암은 열곡대와 중앙화산체에서 나타나며 기반의 심도는 장축을 따라서는 1.5~3 km, 용암대지에서는 1~1.5 km 정도로 나타나며, 한라산 하부에서 최대 5 km로 나타난다. 중력과 자력이상도 모두에서 나타나는 동부 지역의 남북 방향의 이상은 지질도 상에서는 확인되지 않는 단층 또는 파쇄대에 의한 것일 가능성이 있다.

Purpose: Although trauma is the most common cause of death under age 18, Korean national pediatric trauma data has lack of clinical data. This study is to prepare manpower resources, equipment, and make a correct policy decision on pediatric trauma victims Methods: The study enrolled 528 patients under age 16 with traumatic injury visited Wonju Severance Christian Hostpital Trauma Center, from February 12, 2015 to December 31, 2016. We analyzed the distribution of gender, age, place and time of the accident, injury mechanism, injury severity, and injured organ by medical record. Results: The major injury mechanisms were blunt injury in 485 (91.90%), penetrating injury in 27 (5.10%), burn in 13 (2.50%), near drowning in 2 (0.40%), and foreign body ingestion in 1 (0.20%). Ninety-seven (18.4%) patients were injured at home and 67 (12.7%) patients were injured at school. The overall mortality rate was 1.13% (n=6). 5 mortalities were related to automobile accident and one was fall down. Mean Injury Severity Score (ISS) was 4 (2, 8). No statistical significance was observed in the mean ISS between each age group. The peak time of accident occurrence was between 16 and 17 o'clock. The mean ISS was higher in blunt injury group than penetrating injury with statistical significance ($6.50{\pm}7.60$ vs. $3.00{\pm}8.10$; p<0.05). The most common injury site was upper extremity. Mean ISS was highest in thorax injury. However, mean ISS of thorax injury was higher with statistical significance only compared with face, neck and upper extremity injury. Conclusions: We reported our pediatric trauma patients data of our hospital level I trauma center, which is the only one level I trauma center of Gangwon Province. These data is useful to prevent and prepare for pediatric trauma.

Objective : The purposes of this study was to analyze the effects of the stirrup length fitted to the rider's lower limb length and it's impact on less skilled riders during trot in equestrian events. Methods : Participants selected as subjects consisted of less skilled riders(n=5, mean age: $40.02{\pm}10.75yrs$, mean heights: $169.77{\pm}2.08cm$, mean body weights: $67.65{\pm}7.76kg$, lower limb lengths: $97.26{\pm}2.35cm$, mean horse heights: $164.00{\pm}5.74cm$ with 2 type of stirrups lengths(lower limb ratio 74.04%, and 79.18%) during trot. The variables analyzed consisted of the displacement for Y axis and Z axis(head, and center of mass[COM]) with asymmetric index, trunk front-rear angle(consistency index), lower limb joint(Right hip, knee, and ankle), and average vertical forces of horse rider during 1 stride in trot. The 4 camcorder(HDR-HC7/HDV 1080i, Spony Corp, Japan) was used to capture horse riding motion at a rate of 60 frames/sec. Raw data was collected from Kwon3D XP motion analysis package ver 4.0 program(Visol, Korea) during trot. Results : The movements and asymmetric index didn't show significant difference at head and COM, Also, 74.04% stirrups lengths in trunk tilting angle showed significant difference with higher consistency than that of 79.18% stirrups lengths. Hip and knee joint angle showed significant difference with more extended posture than that of 74.04% stirrups lengths during trot. Ankle angle of 79.18% stirrups length showed more plantarflexion than that of 74.04% stirrups lengths. Average vertical force of rider showed significant difference with higher force at 79.18% stirrups lengths than that of 74.04% stirrups lengths during stance phase. Conclusion : When considering the above, 74.04% stirrups length could be effective in impulse reduction with consistent posture in rather less skilled horse riders.

Background: To evaluate the clinicopathologic and demographic characteristics of triple-negative breast cancer (TNBC) patients and to determine differences from non-triple-negative cases. Materials and Methods: A detailed review of the medical records of 882 breast cancer (BC) patients was conducted to obtain information regarding age, menopausal status, height and weight at the time of diagnosis, presence of diabetes or hypertension, and pathologic characteristics of the tumor (tumor size, lymph node status, histologic grade, ER status, PR status, HER2 status, p53 mutation). Body mass index (BMI) was calculated and a value of ${\geq}30$ was considered as indicative of obesity. Results: 14.9% (n=132) of the patients had TNBC. There was no difference among the patients in terms of median age, comorbid conditions and menopausal status. The proportion of medullary, tubular and mucinous carcinomas was significantly higher (15.9%) in the triple-negative (TN) group, while invasive lobular histology was more frequent (8.2%) among non-triple negative (NTN) cases (p<0.001). Grade 3 (G3) tumors were more frequent in the triple-negative group (p<0.001). The rate of p53 mutation was 44.3% in TN tumors versus 28.2% in the NTN group (p<0.001). The two groups were similar in terms of LN metastasis. In the NTN group, the rate of patients with BMI ${\geq}30$ was 53% among postmenopausal patients, while it was 36% among premenopausal women, and the difference was statistically significant (p<0.001). No significant difference was observed in terms of BMI between postmenopausal and premenopausal patients in the TN group (p=0.08). Conclusions: TNBC rates and clinicopathologic characteristics of the Turkish patient population were consistent with the data from Europe and America. However, no relationship between obesity and TNBC was observed in our study. The association between TNBC and obesity needs to be evaluated in a larger patient population.

Objective: This study was an attempt to investigate the effect of levels of fungal (Lentinus sajor-caju) treated oil palm fronds (FTOPF) on digestibility, rumen fermentation, and nitrogen balance in goats. Methods: Four 16 month old male crossbred (Thai Native${\times}$Anglo Nubian) goats with initial body weights of $33.5{\pm}1.7kg$ were randomly assigned according to a $4{\times}4$ Latin square design. Four levels of FTOPF were assigned for feed intake. The experimental treatments consisted of 0%, 33%, 67%, and 100% of oil palm fronds (OPF) being replaced by FTOPF. Results: The results revealed that total dry matter intake and nutrient intake were not influenced (p>0.05) by the inclusion of FTOPF. However, the efficiency values of the digestibility of the dry matter, organic matter, crude protein, neutral detergent fiber, acid detergent fiber, and acid detergent lignin on FTOPF were higher (p<0.05) in treatments with 33%, 67%, and 100% of FTOPF compared with 0% of FTOPF. FTOPF feeding did not change the rumen pH, temperature, and $NH_3-N$. However, the FTOPF levels did affect the total volatile fatty acid (VFA), molar proportion of acetate, propionate, butyrate, ratio of acetic (propionic acid and acetic) plus butyric (propionic acid), and production of $CH_4$. The totals of VFA and propionate was lower in goat fed with 0% of FTOPF than in those of the other groups (p<0.05). The amount of nitrogen retention based on g/d/animal or the percentage of nitrogen retained was the lowest the goat fed with 0% of FTOPF (p<0.05), whereas nitrogen intake, excretion, and absorption were not changed among treatments. Conclusion: Based on this study, FTOPF could be effectively used as an alternative roughage source in total mixed ration diets, constituting at least up to 100% of OPF.

Objective: The aim of this study was to compare overfeeding performance, fatty acid composition, blood chemistry, enzymes and genes expression overfed Xupu and Landes geese. Methods: Sixty male Xupu geese (80 d) and Landes geese (80 d) were selected. After a period of one-week of pre-overfeeding, Xupu and Landes geese were overfed three meals of 550 and 350 g/d, respectively, of a high-carbohydrate diet in the first week of the overfeeding period. The next week, geese were given four meals of 1,200 and 850 g/d, respectively, over 8 to 14 d. Finally, geese were given five meals of 1,600 and 1,350 g/d, respectively, for the last two weeks. Results: After overfeeding for 28 d: Compared with Landes geese, Xupu geese liver weight and liver-to-body weight ratio decreased (p<0.05), while final weight, slaughter weight, total weight gain, abdominal fat weight, and feed-to-liver weight ratio increased (p<0.05). The levels of elaidic acid (C18:1t9), oleic acid (C18:1n-9), eicosenoic acid, and arachidonic acid in the liver of Xupu geese significantly increased (p<0.05), and the levels of myristic acid and stearic acid significantly decreased (p<0.05), while methyleicosanoate acid significantly increased (p<0.05). Xupu geese had higher plasma concentrations of triglyceride and very low density lipoprotein cholesterol (p<0.05), and decreased activities of alanine aminotransferase, aspartate aminotransferase, and lipase (LPS) (p<0.05). Landes geese had higher LPS activity (p<0.05), but lower cholinesterase activity (p<0.05) when compared with Xupu geese. The mRNA expression levels of fatty acid dehydrogenase (FADS) gene, elongase of long-chain fatty acid 1 (ELOVL1) gene, ELOVL5, and acyl-Co A: cholesterol acyltransferase 2 (ACAT2) gene were significantly upregulated (p<0.05) in Landes goose when compared with Xupu geese. Conclusion: This study demonstrates that the liver production performance of Landes geese was better than that of Xupu geese to some extent, which may be closely related to LPS activity, as well as the expression of FADS, ELOVL1, ELOVL5, and ACAT2.

Objective: This study was conducted to determine the effects of stale maize on growth performance, immunity, intestinal morphology, and antioxidant capacity in broilers. Methods: A total of 800 one-day-old male Arbor Acres broilers (45.4±0.5 g) were blocked based on body weight, and then allocated randomly to 2 treatments with 20 cages per treatment and 20 broilers per cage in this 6-week experiment. Dietary treatments included a basal diet and diets with 100% of control maize replaced by stale maize. Results: The content of fat acidity value was higher (p<0.05) while the starch, activities of catalase and peroxidase were lower (p<0.05) than the control maize. Feeding stale maize diets reduced (p<0.05) average daily feed intake (ADFI) throughout the experiment, feed conversion ratio (FCR) during d 0 to 21 and the whole experiment as well as relative weight of liver, spleen, bursa of Fabricius and thymus (p<0.05) on d 21. Feeding stale maize diets decreased jejunum villus height (VH) and VH/crypt depth (CD) (p<0.05) on d 21 and 42 as well as ileum VH/CD on d 42. The levels of immunoglobulin G, acid α-naphthylacetate esterase positive ratios and lymphocyte proliferation on d 21 and 42 as well as lysozyme activity and avian influenza antibody H₅N₁ titer on d 21 decreased (p<0.05) by the stale maize. Feeding stale maize diets reduced (p<0.05) serum interferon-γ, tumor necrosis factor-α, interleukin-2 on d 21 and interleukin-6 on d 21 and 42. Broilers fed stale maize diets had lower levels of (p<0.05) total antioxidative capacity on d 42, superoxide dismutase and glutathione peroxidase on d 21 and 42, but higher (p<0.05) levels of malondialdehyde on d 21 and 42. Conclusion: Feeding 100% stale maize decreased ADFI and FCR, caused adverse effects on immunity and antioxidant function and altered intestinal morphology in broilers.

Objective: This study investigated the effects of oral administration of rumen-protected L-tryptophan (RPL-T) on duodenal starch digestion and gastrointestinal hormones (GIH) secretions using Hanwoo beef steers as the animal models. Methods: Four steers (423±24 kg) fitted with ruminal and duodenal cannulas were employed in a crossover design replicated twice. Treatments were control (basal diet) and RPL-T (basal diet+191.1 mg/kg body weight [BW]) group. Blood and duodenal samples were collected to measure serum GIH levels and pancreatic α-amylase activity at day 0, 1, 3, and 5 (-30, 30, 90, 150, and 210 min) of the study. Samples from each segment of the gastrointestinal tract were collected via ruminal and duodenal cannulas and were used to determine soluble protein and the starch digestion rate at days 6 (-30, 180, 360, and 540 min) and 8 (-30, 90, 270, and 450 min) of the experiment. Results: No significant difference in ruminal pH, NH₃-N, and total volatile fatty acid including the levels of acetate, propionate, butyrate, isobutyrate, valerate, isovalerate, and the acetate-to-propionate ratio was observed between groups (p>0.05). Crude protein uptake was higher and feces starch content was lower in RPL-T group than the control group (p<0.05). The D-glucose contents of feces in RPL-T group decreased at day 5 compared to those in the control group (p<0.05), however, no change was found at day 0, 1, or 3 compared to the control group (p>0.05). Serum cholecystokinin (CCK), melatonin, duodenal pancreatic α-amylase activity, and starch digestion were significantly higher in RPL-T group than the control group (p<0.05). Conclusion: Taken together, oral administration of RPL-T at the rate of 191.1 mg/kg BW consistently increased CCK concentration, pancreatic α-amylase activity in duodenal fluids, and starch digestion rate in the small intestine and thus found to be beneficial.

Purpose: To compare the depiction of brain metastases on contrast-enhanced images with 7.0 tesla (T) and at 1.5T MRI. Materials and Methods: Four consecutive patients with brain metastases were scanned on 7.0T whole-body scanner and 1.5T MRI. A 3D T1-weighted gradient echo sequence (3D T1-GRE) at 1.5T (voxel size = $0.9{\times}0.9{\times}1.5mm^3$ after double-dose, gadoterate meglumine, Gd-DOTA) was compared to a 7.0T 3D T1-GRE sequence (voxel size = $0.4{\times}0.4{\times}0.8mm^3$, single-dose Gd-DOTA) in four patients after a 5 minute delay. The number of contrast-enhancing metastases in MPRAGE images was compared in each patient by two radiologists in consensus. We measured contrast ratio of enhancing brain metastases and white matter in 1.5T and 7.0T. Results: In all four patients 7.0T 3D T1-GRE images after single-dose Gd-DOTA and 1.5T after double-dose Gd-DOTA depicted 11 brain metastases equally. In the quantitative analysis of contrast ratios of enhancing brain metastases and white matter, the 1.5T 3D T1-GRE after double-dose showed an increased contrast ratio compared to 7.0T 3D T1-GRE after single-dose ($0.961{\pm}0.571$ versus $0.885{\pm}0.494$; n = 11 metastases). But this difference was not statistically significant (P = 0.711). Conclusion: Our preliminary results indicate that 7.0T single-dose Gd-enhanced images were not different to 1.5T double-dose Gd-enhanced images for the detection of brain metastases.
