Predicting Breast Cancer Survivability: Comparison of Five Data Mining Techniques
Arihito Endo,Shibata Takeo,Hiroshi Tanaka 대한의료정보학회 2007 Healthcare Informatics Research Vol.13 No.2
Objective: Today in United States, about one in eight women have been affected with breast cancer over their lifetime. Up to today, some various prediction models using SEER (Surveillance Epidemiology and End Results) datasets have been proposed in past studies. However, appropriate methods for predicting the 5 years survival rate of breast cancer have not established. In this study, we evaluate those models to predict the survival rate of breast cancer patients. Methods: Five data mining algorithms (Artificial Neural Network, Naive Bayes , Decision Trees (ID3) and Decision Trees(J48)) besides a most generally used statistical method (Logistic Regression) were used to evaluate the prediction models using a dataset (37,256 follow-up cases from 1992 to 1997). We also used 10-fold cross-validation methods to assess the unbiased estimate of the five prediction models for comparison of performance of each method. Results: The accuracy was 85.8±0.2%, 84.3±1.4%, 83.9±0.2%, 82.3±0.2%, 75.1±0.2% for the Logistic Regression, Artificial Neural, Naive Bayes, Decision Trees (ID3), Decision Trees(J48), respectively. Although the accuracy of Logistic Regression showed the highest performances, the Decision Trees (J48) was the lowest one. Conclusions: The accuracy of Logistic Regression was the best performances, on the other hand Decision Trees (J48) was the worst. Artificial Neural Network indicated relatively high performance.

Topographical variations of the incisive canal and nasopalatine duct in human fetuses
Ji Hyun Kim,Shunichi Shibata,Hiroshi Abe,Gen Murakami,José Francisco Rodríguez-Vázquez 대한해부학회 2019 Anatomy & Cell Biology Vol.52 No.4
The incisive canal for nerves and vessels is generally thought to run along a suture between the incisive bone (IN) and maxilla. In contrast, there was a report saying the canal passes through the IN or primary palate in human fetuses. Examination of sagittal and frontal sections from 69 fetuses (31 of gestational age [GA] 9–15 weeks and 38 of GA 26–34 weeks) showed that the canal often penetrated the IN at the nasal half of its course and that, in other fetuses, the canal penetrated the IN along its entire course, irrespective of involvement of the nasopalatine duct. Canals developing in and corresponding to parts of the suture resulted in partial enlargement of the thin and tight sutures, which contained loose tissue, vessels, nerves and even a duct. Small processes of the IN were identified as upper irregular parts continuous with inferior main masses of bone in frontal sections but as bone fragments in sagittal sections. In some sections, a thin layer of the maxilla along the canal covered the medial or inferior aspect of the IN. Therefore, the incisive canal with or without duct exhibited a spectrum of variations in topographical relation to the IN-maxillary border. Because the primitive oronasal communication passes through the suture, the nasopalatine duct may have originated from the secondary developed elongation of the nasal epithelium at midterm. A large incisive fossa along the midline on the oral surface of the palate might make a macroscopic finding of variants difficult even in adults.
Spin Torque and Force due to Current for General Spin Textures
Tatara, Gen,Kohno, Hiroshi,Shibata, Junya,Lemaho, Yann,Lee, Kyung-Jin Physical Society of Japan 2007 Journal of the Physical Society of Japan Vol.76 No.5
<P>The nonadiabatic correction to spin transfer torque arising from fast-varying spin texture is calculated treating the conductions electron fully quantum mechanically. The torque is nonlocal in space, and is shown to be equivalent to a force (due to momentum transfer) acting on the center of mass of the texture. Another kind of force exists in the adiabatic regime, and it is identified to be of topological origin. These forces are shown to be the counter-reactions of electric transport properties, resistivity and the Hall effect.</P>

TAKANAO, OTSUKA,OHKAWA, TAKEHIKO,SHIBATA, TOSHIHIRO,OKU, TERUO,OKUHARA, MASAKUNI,TERANO, HIROSHI,MASANOBU KOHSAKA,IMANAKA, HIROSHI 한국미생물 · 생명공학회 1991 Journal of microbiology and biotechnology Vol.1 No.3
A new angiogenesis inhibitor, FR-118487 was obtained by chemical modification of FR-111142 which was isolated from the fermentation products of Scolecobasidium arenarium F-2015. The antiangiogenic activity of FR-118487 was compared with that of the parent compound, FR-111142. In the endothelial cell proliferation test in vitro and the anglogenesis in the chick embryo chorioallantoic membrane assay, FR-118487 had about 5∼10 times stronger antiangiogenic activities than FR-111142. In addition, FR-118487 inhibited the angiogenesis in the rabbit corneal assay and suppressed the solid tumor growth in mice. These findings showed that FR-118487 would be a unique antiangiogenic agent with promising antitumor activity.

In March 1997, we developed a new training method, called ‘tree joint training system’, for Japanese pear (Pyrus pyrifolia) in order to realize early maturing orchard and labor saving management. This method is based on grafting, joining many trees and creating one linearly congregated tree. In this system, however, trees become more vigorous than an individual tree. One effective method of vigor control is to cut off some of the main stems in the congregated trees. We have investigated the appropriate season for cutting off the main stem by monitoring physiological parameters and sap flow in the joined trees. From May to October in 2007, the effects of cutting off the stem of central tree of three ‘Kosui’ joined trees on photosynthesis, stomatal conductance, and transpiration rate were investigated. When cutting was done in May and July, photosynthesis, stomatal conductance, and transpiration rate at the central tree immediately showed drastic reduction, and leaves of the central tree were wilted, while no clear effect was observed in the top and bottom trees, suggesting that short term effect on production and water status by cutting off stem of the central one occurs only in the central tree, not in the adjacent trees. In the cutting treatment of September and October, there was very little reduction in transpiration rate in all the joined trees, suggesting that there might be very little short term effect. Flow rate of joined trees in late October after cutting stem off was investigated. Immediately after cutting, flow rate of the central tree rapidly reduced from 32 to 0 gㆍh?¹ in 1 h, but no clear change was seen in the top and bottom trees. There was no visible change in leaves of the pear trees. Thus, soon after joining, in the spring and summer, cutting off treatment would sharply affect the transpiration and water status of the tree; however in the late fall, short term effect was limited because leaf activity was relatively low, though the sap flow was affected. In conclusion, season of cutting off the stem for vigor control in the end of September through the end of October might be appropriate for avoiding short term stresses.

Using multi-trait animal model BLUP, selection was conducted over seven generations for growth rate (DG), real-time ultrasound loin-eye muscle area (LEA), backfat thickness (BF), and intramuscular fat content (IMF) to develop a new line of purebred Duroc pigs with enhanced meat production and meat quality. This study was intended to investigate the relationship between restriction fragment length polymorphism (RFLP) of a heart fatty acid-binding protein (H-FABP) gene and intramuscular fat content (IMF) of this Duroc purebred population. The present experiment examined the RFLP of 499 slaughtered pigs. The DNA was separated from the blood or ear tissue of the pigs, which were slaughtered at 105 kg of body weight. Intramuscular fat content of the longissimus muscle was measured using chemical analysis. A significant difference was detected in the breeding value of IMF among the H-FABP PCR RFLP genotypes. The AA genotype has a significantly larger positive effect on the IMF breeding value than do the Aa and aa genotypes for the MspI RFLP. In addition, the DD genotype has a significantly greater positive effect on IMF breeding value than the Dd and dd genotypes for the HaeIII RFLP. For the HinfI RFLP, the hh genotype has a significantly larger positive effect on IMF breeding value than the HH genotype. Multiple regression analysis was performed using the IMF breeding values as the dependent variable and the three H-FABP genotypes as independent variables. Results revealed that the contribution of the genotypes to variation in IMF breeding values was approximately 40%. These results demonstrated that H-FABP RFLPs affect IMF in this Duroc population.
