Generally, it is known that the spleen accompanied by liver cirrhosis is hypertrophied or enlarged. We examined the wave pattern of the spleen by using abdominal CT images of a patient with liver cirrhosis, and found that they are different from those of a person with a normal liver In the abdominal CT image of the patient with liver cirrhosis, there is a deep wave part on the left side of the spleen. In the case of the normal liver, there are waves on the left side, but they aren't deep. Therefore, the total area of waving parts of the spleen with liver cirrhosis is found to be greater than that of the spleen with the normal liver. Moreover, when examining circularity by abstracting the waves of the spleen from the image iO liver cirrhosis, we found they are more circular than those of the spleen accompanied by a normal liver. This paper suggests an automatic method to diagnose splenic enlargement by using the wave pattern of the spleen in abdominal CT images on the basis of the two principles. It tells us that we can judge if the abdomen has a focal splenic enlargement automatically, without the manual test of the size of spleen, only with the shape of spleen.

Increasing the strength of structural materials allows their self-weight to be reduced and this, in turn, enables the structures to satisfy esthetic requirements. The yield strength of high-performance steel is almost 480 MPa, which is approximately 50% higher than that of general structural steel. The use of high strength materials, however, makes the sections more slender, which can potentially result in significant local stability problems. The strength of slender element sections might be governed by their elastic buckling behavior, and the elastic buckling strength is very sensitive to the boundary conditions. Because the web provides the boundary conditions of the compressive thin-flange, the stiffness of the web can affect the elastic buckling strength of the flange. In this study, therefore, the effects of the flange and web slenderness ratios on the elastic flange local buckling of I-girders subjected to a pure bending moment were evaluated by finite element analysis (FEA). The analysis results show that the elastic local buckling strength and buckling modes were affected not only by the web support conditions, but also by the flange and web slenderness ratios.

비만 특히 복부비만은 여성의 임신 및 출산에 많은 악영향을 미친다. 비만이 가임력에 영향을 미치는 기전은 명확히 밝혀지지는 않았지만, functional hyperandrogenism과 insulin resistance에 수반된 hyperinsulinemia가 중요한 역할을 하리라 여겨진다. 또한 지방조직은 활발하게 대사 작용이 일어나는 장소로서 steroid hormone을 modification 시키고, 여러 가지 adipokine들을 분비시키는데 이런 지방조직의 분비물들은 생식계에 영향을 미친다. 비만이 생식계에 미치는 영향은 간략히 다음 표와 같이 정리할 수 있다 (Table 3). 특히 PCOS 환자에서 비만은 hyperinsulinemia에 의한 난소의 steroidogenesis 증가와 SHBG의 감소에 연관되어 hyperandrogenism 과 무배란의 원인으로 작용한다. 비만은 약물에 의한 배란유도 및 체외수정의 성공률 또한 떨어뜨리며， 임신이 되더라도 자연 유산, 조산, 임신성 당뇨, 임신성 고혈압 등의 위험은 높인다. 이와 같이 최근 급격히 증가하는 비만은 여성의 건강 특히 생식계에 많은 문제를 야기시킨다. 특히 청소년기의 비만은 성인이 된 뒤 PCOS로 발전하여 불임, 심혈관 질환 등과 같은 많은 합병증을 일으킬 수 있으므로 세심한 주의를 기울여야 하겠다.

This study was designed to investigate the relationships of depressed mood with obesity, blood and urinary compositions, and dietary habits in Koreans at the age of 40, a critical transition to the middle adulthood stage. A total of 27,684 people who have taken the Life Transition Period Health Examination at the Korea Association of Health Promotion in 2011 were divided into two groups; the depressed mood group (DG) and the non-depressed group (NG) according to results of the primary questionnaire for mental health. The results were analyzed using the health examination criteria of the National Health Insurance Corporation. Women and medicaid recipients showed higher incidence of depressed mood than men and health insurance subscribers. People with underweight in BMI or abdominal obesity showed correlation with depressed mood, while there was no significant relationship with metabolic syndrome. Regarding blood and urinary compositions, DG was related to a higher level of hemoglobin and lower levels of HDL-cholesterol and triglyceride, although the relationships diminished after adjustment for other confounder effects. According to dietary habits, more people in DG were categorized as a group for "Needs Much Improvement", and the odds ratio of the depressed mood showed a significant increase. Significant difference regarding the frequency of food items such as milk products, animal proteins, Kimchi, and fruits was observed between DG and NG. In addition, a higher portion of subjects in DG did not consume regular meals and various kinds of food. In conclusion, the depressed mood of 40 year-old adults was significantly related to underweight, higher waist measurement, and undesirable dietary habits. Results of our study can be applicable as a basic resource for development of effective nutrition counseling and education programs for improvement of mental health promotion during the critical transition to the middle adulthood stage.

비만은 제2형 당뇨병, 심혈관계 질환, 그리고 암을 비롯해 각종 질병의 위험인자로 작용한다. 비만은 낮은 수준의 전신성 염증상태로 간주되며, 비만시 증가하는 염증성 분자는 제2형 당뇨병 또는 동맥경화등의 비만성 질병 발생과정에 깊이 관여한다. 따라서, 염증제어는 비만성 질환제어를 위해 매우 중요하다. 지방세포 비대에 따른 지방세포 기능이상은 아디포사이토카인의 분비 이상을 초래하고, 비만성 질환의 발생 및 촉진자로 작용한다. 비만환자에게서의 MCP-1과 같은 염증성 아디포사이토카인의 분비 제어는 비만성 질환을 예방하거나, 또는 질병 발생 및 진행을 지연시키는 전략적 가치가 있을 것으로 사료된다. 지방세포가 분비하는 케모카인 가운데 MCP-1은 비대한 지방조직내로의 대식세포의 침윤 및 활성화를 유도하며, 특히 비대한 지방조직에서의 염증반응을 증폭시키는 역할을 한다. MCP-1은 내 장지 방조직에서 특히 그 분비량이 높았고, 따라서, 복부비만 관련 질환의 타겟분자로서 가치가 있을 것으로 생각된다. 또한, MCP-1 작용을 저해하는 항염증성 phytochemical은 비만으로 인한 염증성 질환의 발생을 지연시키거나, 즉 예방적인 차원에서 유용할 것으로 사료된다.

Purpose: The purpose of this study was to assess the diagnostic value of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) for detecting the lymph node (LN) metastasis of gastric cancer. Materials and Methods: 119 patients (M : F=89 : 30; mean age: 64) with gastric cancer were referred for preoperative FDG-PET/CT scanning and spiral enhanced abdominal pelvic CT from June 2006 to July 2008, and these were the subjects of our study. All the patients underwent curative radical gastrectomy and lymph node dissection. A final diagnosis was made for all the patients by the histology of the surgical specimens. Results: Both PET/CT and enhanced CT showed similar sensitivity for detecting regional lymph node metastasis (32.6% vs 39.5%, respectively). PET/CT was more accurate than enhanced CT for detecting regional lymph node metastasis (67.2% vs 63.0%, respectively), and PET/CT showed better specificity (86.8% vs 76.3, respectively) and a better positive predictive value (PPV) (58.3% vs 48.6%, respectively). PET/CT showed better specificity (98.0% vs 88.2%, respectively) and accuracy (79.4% vs 73.9%, respectively) than enhanced CT for detecting early gastric cancer. PET/CT showed better specificity (64.0% vs 52.0%, respectively), a better PPV (60.9% vs 57.1%), a better negative predictive value (NPV) (48.5% vs 46.4%, respectively) and better accuracy (53.6% vs 51.8%, respectively) than enhanced CT for detecting advanced gastric cancer. Conclusion: FDG-PET/CT is more usefulness than enhanced CT for making the preoperative diagnosis of regional LN metastases from gastric cancers.

In this study, we investigated the improvement effect of obesity by treatment with a developed low frequency electrical stimulation system. Thirty female in their 20's as an experiment subjects divided 3 groups(control, commercialized device, developed device) were treated with electrical stimulation on abdomen for 4 weeks. The body weight, body mass index(BMI), waist-hip ratio(WHR), muscle strength, muscle(transverse abdominis(TrA), internal obliquus abdominis(IO), external obliquus abdominis(EO)), fat thickness and abdominal surface temperature were measured by electromyogram(EMG), ultrasound and digital infrared thermal image(DITI). In the result, the body weight and BMI were decreased. Subcutaneous abdominal fat were significantly reduced after 4 weeks. The muscle strength and TrA muscle thickness was increased 13.2%(p<0.05), and 35.5%, respectively. The fat thickness showed decrease in abdomen (p<0.05). Infrared measurement on abdominal surface temperature as a parameter of improvement in blood circulation was significantly increased(p<0.05). Therefore, the low frequency stimulation showed positive effects on parameters of the obesity improvement.

Purpose: The purpose of this study was to verify the effect of aromatherapy massage on abdominal fat and body image in post-menopausal women. Method: A Non-equivalent control group pre-post test Quasi-experimental design of random assignment was applied. All subjects received one hour of whole body massage as treatment by the same researcher every week for 6 weeks. Participants also massaged their own abdomen two times everyday for 5 days each week for 6 weeks, The two groups used different kinds of oil. The experimental group used 3% grapefruit oil, cypress and three other kinds of oil. The control group used grapeseed oil. Data was collected before and after the treatment using Siemens Somatom Sensation 4, a tape measure and MBSRQ. Data was analyzed by ANCOVA using the SPSS/PC+Win 12 Version. Result: Abdominal subcutaneous fat and waist circumference in the experimental group significantly decreased after aromathetapy massage compared to the control group. Body image in the experimental group was significantly better after aromathetapy massage than in the control group. Conclusion: These results suggest that Aromatheapy massage could be utilized as an effective intervention to reduce abdominal subcutaneous fat, waist circumference, and to improve body image in post-menopausal women.
