  • Recently, data sharing between enterprises or organizations is required matter for task cooperation. In this process, when the enterprise opens its database to the affiliates, it can be occurred to problem leaked sensitive information. To resolve this problem it is needed to hide sensitive information from the database. Previous research hiding sensitive information applied different heuristic algorithms to maintain quality of the database. But there have been few studies analyzing the effects on the items modified during the hiding process and trying to minimize the hided items. This paper suggests eFP-Tree(Extended Frequent Pattern Tree) based FP-Tree(Frequent Pattern Tree) to hide sensitive frequent itemsets. Node formation of eFP-Tree uses border to minimize impacts of non sensitive frequent itemsets in hiding process, by organizing all transaction, sensitive and border information differently to before. As a result to apply eFP-Tree to the example transaction database, the lost items were less than 10%, proving it is more effective than the existing algorithm and maintain the quality of database to the optimal.

  • Fibrinolytic protease activity was detected in the fruit body of Pleurotus sajor-caju using a fibrin plate method. Two fibrinolytic activities (FPI and Ⅱ) were found at the regions of 14.5 and 86.0 kDa by using gel-filtration column chromatography. FPⅡ was identified as an alkaline protease, whereas FPⅠ was a neutral protease. Both were inhibited by phenanthrolin and EDTA, suggesting that they are metalloprotease. Inactivated enzyme activities were restored by adding Co/sup 2+/ or Zn/sup 2+/. Iodoacetate inhibited FPⅠ, but not FPⅡ. Both enzymes cleaved B/sub β/ and γ chains of the human fibrinogen. FPⅡ showed a preference to hydrophobic and bulky residues of nitroanilidine compounds as substrates, whereas FPⅠ preferred positively charged residues.

  • This study was conducted to investigate preferred clothing selected by females for thermal comfort in follicular phase (FP) and luteal phase (LP) of the menstrual cycle. Eight healthy college students volunteered as subjects. They stayed for 60 minutes at $25^{\circ}C$, 55%RH (stage 1) for baseline followed by a 60 minute stay at 2$0^{\circ}C$, 55%RH (stage 2) in a climatic chamber. Obtained results were analyzed using paired t-test and repeated measures of ANOVA. Arm and hand skin temperatures were maintained higher in FP than in LP, while mean skin temperature did not show any significant difference between FP and LP. The subjects selected additional clothing faster in FP than in LP. Six of the subjects wore heavier clothing in FP than in LP, while two of them wore heavier in LP than in FP.

  • Let S and R be rings and SCR a semidualizing bimodule. We introduce the notion of GC-FPn-injective modules, which generalizes GC-FP-injective modules and GC-weak injective modules. The homological properties and the stability of GC-FPn-injective modules are investigated. When S is a left n-coherent ring, several nice properties and new Foxby equivalences relative to GC-FPn-injective modules are given.

  • This paper presents the separation performance of the linearly mixed image signals with additive noises by using an independent component analyses(ICAs) of the fixed-point(FP) algorithm based on Newton and secant method, respectively. The Newton's FP-ICA uses the slope of objective function, and the secant's FP-ICA also uses the tangent line of objective function. The 2 kinds of ICA have been applied to the 2 dimensional 2-image with $512\times512$ pixels. Then Gaussian noise and Laplacian noise are added to the mixed images, respectively. The experimental results show that the Newton's FP-ICA has better the separation speed than secant FP-ICA and the secant's FP-ICA has also the better separation rate than Newton's FP-ICA. Especially, the Newton and secant method gives relatively larger improvement degree in separation speed and rate as the noise increases.

  • A exisiting recommedation system using association rules has the problem, such as delay of processing speed from a cause of frequent scanning a large data, scalability and accuracy as well. In this paper, using a Implicit method which is not used user's profile for rating, we propose the personalized recommendation system which is a new method using the FP-tree mining based on RFM. It is necessary for us to keep the analysis of RFM method and FP-tree mining to be able to reflect attributes of customers and items based on the whole customers' data and purchased data in order to find the items with high purchasability. The proposed makes frequent items and creates association rule by using the FP-tree mining based on RFM without occurrence of candidate set. We can recommend the items with efficiency, are used to generate the recommendable item according to the basic threshold for association rules with support, confidence and lift. To estimate the performance, the proposed system is compared with existing system. As a result, it can be improved and evaluated according to the criteria of logicality through the experiment with dataset, collected in a cosmetic internet shopping mall.

  • While many fertility preservation (FP) options now exist for reproductive-aged cancer patients, access to these services continues to be limited. A comprehensive FP program should be organized to serve oncofertility patients effectively. Also, much effort is needed from various individuals-patients, specialists from various fields, and consultants-to facilitate FP in a timely manner. Various challenges still exist in improving access to FP programs. To improve access to FP treatment, it is important to educate oncologists and patients via electronic tools and to actively navigate patients through the system. Reproductive endocrinology practices that receive oncofertility referrals must be equipped to provide a full range of options on short notice. A multidisciplinary team approach is required, involving physicians, nurses, mental health professionals, office staff, and laboratory personnel. The bottom line of FP patient care is to understand the true nature of each patient's specific situation and to develop a patient flow system that will help build a successful FP program. Expanding the patient flow system to all comprehensive cancer centers will ensure that all patients are provided with adequate information regarding their fertility, regardless of geography.

  • The fundamental period (FP) is one of the most critical parameters for the seismic design of structures. In the reinforced concrete (RC) infilled frame, the infill walls significantly affect the FP because they change the stiffness and mass of the structure. Although several formulas have been proposed for estimating the FP of the RC infilled frame, they are often associated with high bias and variance. In this study, an efficient soft computing model, namely the group method of data handling (GMDH), is proposed to predict the FP of regular RC infilled frames. For this purpose, 4026 data sets are obtained from the open literature, and the quality of the database is examined and evaluated in detail. Based on the cleaning database, several GMDH models are constructed and the best prediction model, which considers the height of the building, the span length, the opening percentage, and the infill wall stiffness as the input variables for predicting the FP of regular RC infilled frames, is chosen. The performance of the proposed GMDH model is further underscored through comparison of its FP predictions with those of existing design codes and empirical models. The accuracy of the proposed GMDH model is proven to be superior to others. Finally, explicit formulas and a graphical user-friendly interface (GUI) tool are developed to apply the GMDH model for practical use. They can provide a rapid prediction and design for the FP of regular RC infilled frames.

  • Background: Corticosteroid is most potent and effective anti-inflammatory medication currently available and inhaled form has been used in the long-tenn control of asthma. Fluticasone propionate(Flixotide/Flovent: FP) is highly potent and topically active inhaled corticosteroid and has at least twice the potency of beclomethasone dipropionate(BDP) in the control of asthma. The aim of this study was to compare the efficacy of FP and BDP in several aspects. Method: Fifty patients with asthma were treated in a randomized, parallel group study of 4 weeks duration. During 2-week run-in period $\beta_2$-agonist was administered. After run-in period, FP $500{\mu}g/day$ was administered via Diskhaler or BDP $800{\mu}g/day$ via reservoir dry-power device. During the run-in and treatment period, morning and evening peak expiratory flow rate(PEFR) were measured daily. Daytime and nighttime asthma symptoms, daytime and night-time rescue bronchodilator use were checked daily. $FEV_{1.0}$ and FVC were measured biweekly in both groups. Results: Three patients treated with FP and seven patient treated with BDP were dropped out. Therefore forty patients completed the study. Morning and evening PEFR was increased and diurnal variation of PEFR decreased significantly in both groups. $FEV_{1.0}$ increased significantly in FP treatment group but not in BDP group. There were also improvements in daytime and night-time asthma symptoms, daytime and night-time rescue bronchodilator use in both groups after treatment There were no significant difference between groups in any of the efficacy parameters. Therapeutic effects were demonstrated earlier in patient treated with FP than BDP. Conclusion: In this study, $500{\mu}g/day$ fluticasone propionate was as effective as $800{\mu}g/day$ beclomethasone dipropionate in the control of asthma. Therapeutic effects were demonstrated earlier in patient treated with FP than BDP without adverse effect.
