Background: This study was conducted to investigate preoperative carcinoembryonic antigen (CEA) as a prognostic factor in colorectal cancer. Methods: Between January 2000 and July 2011, 1298 patients with primary adenocarcinoma colorectal cancer without metastasis, who underwent curative resection were retrospectively identified. The patients were divided into two groups according to serum CEA level at primary diagnosis: a high CEA (HCEA) group (serum CEA ${\geq}6ng/mL$) and a normal CEA (NCEA) group (serum CEA <6 ng/mL). A 1:1 propensity score matching analysis was applied to reduce bias. Finally, 364 patients were enrolled in this study. Matched variables were age, gender, preoperative chemoradiotherapy, tumor site, cell differentiation and pathologic stage. Results: The clinicopathological characteristics of the two groups did not differ significantly difference. The systemic metastasis rate was 16.5% (30/182) and 25.3% (46/182) in the NCEA and HCEA groups, respectively (p=0.039). There were no significant differences in local recurrence or metastatic sites between groups. The 5-year disease-free survival (DFS) rate of the HCEA group was worse than that of the NCEA group; however, there was no significant difference in overall survival between the two groups. Conclusion: Elevated preoperative CEA was related to frequent systemic recurrence and low DFS. Therefore, elevated preoperative CEA could be considered a prognostic factor for worse clinical outcomes in patients with colorectal cancer.

We investigated the quality characteristics of cookies prepared after the addition of various concentration of used guava leaf powder(0%, 1%, 3%, 5%, all w/w) as a substitute for flour. In this study, as guava leaf powder concentration rose, there was a decrease in the water content level. In addition, color, spread factor, hardness and sensory evaluation of the cookies were examined. The results showed that with an increase in guava leaf powder concentration, the L value decreased significantly, while the values for a and b of cookies increased when more guava leaf power was added to cookies. The spread factor of cookies decreased, but the hardness of cookies increased significantly, as guava leaf powder concentration increased. Cookies containing 0% and 3% of guava leaf powder showed a similar sensory evaluation score in terms of color, taste and flavor of the cookies. In the case of texture and overall consumer acceptability, cookies with 3% of guava leaf powder showed the highest score.

This study aims to the influenced factor analysis of spinal cord independence measure(SCIM), on walking velocity, walking endurance, time up & go(TUG), and subject characteristics. The subject of this study were 12 persons with incomplete spinal cord injury(ASIA C, D). All subject ambulatory with or without an assistive device. All participants were assessed on SCIM(score), walking velocity(m/s), walking endurance(m) and TUG(s). The data were analyzed using independent t-test and stepwise multiple regression. The results revealed that no statistical difference was noted in subject characteristics among SCIM, walking velocity, walking endurance, TUG(p>0.5). The independence score, breathing-sphincter control and ambulation were important factors in TUG(31.4%). The results suggest that SCIM may be an inappropriate assessment tool to predict gait ability of patient with incomplete spinal cord injury. Further study about gait speed, gait endurance and TUG by change of SCIM is needed using to patient of incomplete spinal cord injury.

Ulcerative colitis (UC) is a chronic inflammatory bowel disease characterized by abdominal pain, rectal bleeding and diarrhea. Gastrodia elata Blume (GE) has been used for the treatment of various diseases including neurodegenerative diseases and inflammatory disease. However, there has been no information on whether GE regulates intestinal inflammation. The aim of this study is to elucidate whether GE can protect against dextran sulfate sodium (DSS)-induced colitis in a mouse model. The colitis mice were induced by drinking water containing 5% DSS for 7 days. Body weight, colon length and clinical score were assessed to determine the effects on colitis. The levels of inflammatory cytokines, tumor necrosis factor $(TNF)-{\alpha}$ and interleukin (IL)-6 in colitis tissue were also measured. The results showed that mice administrated with DSS showed clinical signs including weight loss and reduced colon length. GE inhibited the DSS-induced loss of body weight and shortening of colon and increased Disease activity index score. Additionally, we observed that GE suppressed the levels of $TNF-{\alpha}$ and IL-6 in DSS-treated colon tissues. Collectively, these findings provide experimental evidence that GE might be a useful therapeutic agent for patients with UC.

In this paper, we propose a recommendation system based on the latent factor model using matrix factorization, which is one of the most commonly used collaborative filtering algorithms for recommendation systems. In particular, by introducing the concept of creating a list of recommended content and a list of non-preferred recommended content, and removing the non-preferred recommended content from the list of recommended content, we propose a method to ultimately increase the satisfaction. The experiment confirmed that using a separate list of non-preferred content to find non-preferred content increased precision by 135%, accuracy by 149%, and F1 score by 72% compared to using the existing recommendation list. In addition, assuming that users do not view non-preferred content through the proposed algorithm, the average evaluation score of a specific user used in the experiment increased by about 35%, from 2.55 to 3.44, thereby increasing user satisfaction. It has been confirmed that this algorithm is more effective than the algorithms used in existing recommendation systems.

Background: The Glasgow Prognostic Score (GPS) is calculated from measured CRP and albumin levels. We here evaluated the significance of the GPS in patients with resected pulmonary adenocarcinoma. Materials and Methods: The present study included 156 patients with lung adenocarcinoma who underwent lobectomy at Kanazawa Medical University between 2002 and 2012. Classification was into three groups: those with normal albumin (>=3.5 g/dl) and C-reactive protein (CRP) (<=1.0 mg/dl) levels were classified as GPS 0 (n =136), those with low albumin (<3.5 g/dl) or elevated CRP (>1.0 mg/dl) levels as GPS 1 (n = 16), and those with low albumin (<3.5 g/dl) and elevated CRP (>1.0 mg/dl) levels as GPS 2 (n = 4). We retrospectively investigated relationships between the patient characteristics including the GPS, and disease-free survival and cancer-specific survival. Results: The pathological stages of the patients were as follows: IA (n=78, 50%), IB (n=31, 19.9%), IIA (n=20.0, 12.8%), IIB (n=9.0, 5.7%), and IIIA (n=18.0, 11.5%). Lobectomy was performed in all cases. The average GPS was 0.15 (0-2) and showed significant relationships with stage and tumor size. The 2-year survival rates in patients with GPS0, 1 and 2 were 81.4%, 38.4%, and 25.0%, respectively. Clear correlations were noted with both cancer-specific survival and disease-free survival. Furthermore, multivariate analysis revealed that GPS was a significant prognostic factor. Conclusions: The GPS could be a prognostic factor for patients with resected pulmonary adenocarcinoma.

On the general trends of weight control for slimness, this study surveyed and compared eating attitude influenced by eating disorder, eating habits, and nutrition knowledge by obesity index in middle school girls. The purpose of this study was to investigate the eating disorders and eating habits, and analyzed these data by degree of obesity. This will provide basic information of nutrition education for adolescents who need to have proper body shape and dieting habits. This survey was conducted to one of girls' middle school in Incheon and all the data was analysed by SAS(Statistical Analysis System) program. The average height, weight and PIBW were 158.7cm, 48.2kg, and 93.9% in students. However, 50.8% of students were underweight or severely underweight. Most of female students perceived that they were normal or overweight even though they had underweight or normal. There was a significant difference in experience and intention of weight control by degree of obesity. In the overweight group, EAT-26 score tendency was high, especially preoccupation with losing weight(factor 1). It shows that obesity index had meaningful correlation with EAT-26 score and factor1. In dietary habit, overweight group showed more irregular meals tendency, and overeat frequently. On the other hand, this group had lower frequency and of smaller amount snacks. The intake frequency of meals and snacks showed in the affirmative way regardless of degree of obesity. The average score for nutrition knowledge about calorie and weight control was low. Correct answer rates were increased in higher overweight group. In conclusion, teenage girls who concerned too much about their slim body image need to be educated about accuracy concept of the body image. Also, practical and systematic nutrition education should be done for the correct nutrition knowledge and its application ability of individuals.
