Recently due to large-scale data spread in digital economy, the era of big data is coming. Through big data, unstructured text data consisting of technical text document, confidential document, false information documents are experiencing serious problems in the runoff. To prevent this, the need of art to sort and process the document consisting of unstructured text data has increased. In this paper, we propose a novel text classification scheme which learns some data sets and correctly classifies unstructured text data into two different categories, True and False. For the performance evaluation, we implement our proposed scheme using $Na{\ddot{i}}ve$ Bayes document classifier and TF-IDF modules in Python library, and compare it with the existing document classifier.

This paper describes an area-efficient design of SHA-256 hash function that is widely used in various security protocols including digital signature, authentication code, key generation. The SHA-256 hash processor includes a padder block for padding and parsing input message, so that it can operate without software for preprocessing. Round function was designed with a 16-bit data-path that processed 64 round computations in 128 clock cycles, resulting in an optimized area per throughput (APT) performance as well as small area implementation. The SHA-256 hash processor was verified by FPGA implementation using Virtex5 device, and it was estimated that the throughput was 337 Mbps at maximum clock frequency of 116 MHz. The synthesis for ASIC implementation using a $0.18-{\mu}m$ CMOS cell library shows that it has 13,251 gate equivalents (GEs) and it can operate up to 200 MHz clock frequency.

Objectives To systematically explore the effects of acupuncture treatment for rotator cuff disorders and review the clinical trials. Methods We searched 9 electronic databases (PubMed, Cochrane central, Embase, China National Knowledge Infrastructure [CNKI], Korea Institute of Science and Technology Information [KISTI], National Digital Science Library [NDSL], Korean studies Information Service System [KISS], Research Information Sharing Service [RISS], Oriental Medicine Advanced Searching Integrated System [OASIS]) to find randomized controlled trials that used acupunture treatment for rotator cuff disorders. We assessed the designs of the randomized controlled trials and the method of acupuncture treatment according to the Standards for Reporting Interventions in Clinical Trials of Acupuncture (STRICTA). The methodological quality of randomized controlled trials were assessed using the Cochrane Risk of Bias (RoB) tool. Results Total 5 trials were reviewed. 4 out of 5 randomized clinical trials reported meaningful effects of acupuncture treatments compared to control group. However risk of bias seemed high. Conclusions Although the results suggest that acupuncture treatment has favorable effects for rotator cuff disorders, most of the studies included methodologically high risk of bias. Thus, well designed randomized clinical trials which evaluate the effects of acupuncture treatment for rotator cuff disorders should be encouraged.

Random Forest (RF), a representative ensemble technique, was applied to automatic classification of journal articles in the field of library and information science. Especially, I performed various experiments on the main factors such as tree number, feature selection, and learning set size in terms of classification performance that automatically assigns class labels to domestic journals. Through this, I explored ways to optimize the performance of random forests (RF) for imbalanced datasets in real environments. Consequently, for the automatic classification of domestic journal articles, Random Forest (RF) can be expected to have the best classification performance when using tree number interval 100~1000(C), small feature set (10%) based on chi-square statistic (CHI), and most learning sets (9-10 years).

Purpose: This systematic review was planned and performed in order to determine the clinical effectiveness of acupuncture for non-alcoholic fatty liver disease (NAFLD). Methods: We searched related randomized controlled trials in several medical online databases, including China National Knowledge Infrastructure (CNKI), Excerpta Medica dataBASE (EMBASE), Public/Publisher MEDLINE (PubMed), Cochrane Central Register of Controlled Trials (CENTRAL), National Digital Science Library (NDSL), and Research Information Sharing Service (RISS). NAFLD related outcomes were extracted from the included trials and meta-analyzed. Results: From the 8 included trials, the values of the following examinations were extracted: liver ultrasonography, liver CT, body fat CT, aspartate transaminase (AST), alanine transaminase (ALT), gamma-glutamyltransferase (GGT), total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL) cholesterol, high density lipoprotein (HDL) cholesterol, fasting blood sugar (FBS), hosmeostatic model assessment for insulin resistance (HOMA-IR), weight, body mass index (BMI), waist hip ratio (WHR), obesity degree, body fat mass, body fat rate, leptin, malondialdehyde (MDA), and super oxide dismutase (SOD). In the 4 outcomes, cure rate in liver ultrasonography (RR=1.56; 95%CI=1.05~2.31; P=0.03), cure rate in liver CT (RR=2.23; 95%CI=1.33~3.72; P=0.002), TC (MD=-0.78; 95%CI=-1.41~-0.15; P=0.02), and TG (MD=-2.05; 95%CI=-3.88~-0.21; P=0.03), acupuncture was more effective than the control intervention. Conclusions: In this meta-analysis, acupuncture relieved hepatic steatosis, and reduced TC, and TG in NAFLD patients. more well-planned studies are still needed due to the heterogeneity and the considerable methodological flaws in the analyzed trials.

Purpose: The aim of this study was to determine the related factors for psychological crises in Korean middle aged adults. Methods: RISS, KISS, National Assembly Digital Library, CINAHL, and PubMed were searched for relevant articles published until October 3, 2016. Finally, a total of 23 studies were included. Meta-analysis of the studies was conducted using Comprehensive Meta-Analysis 3.0 software to calculate the effect size. Results: The related variables of psychological crisis were categorized into 23 variables and 5 factor groups. The effects size (ES) of the overall defensive variables was -0.28. In the defensive factors, the psychological factor (ES=-0.67), followed by cognitive and behavioral factor (ES=-0.34), physical factor (ES=-0.31), and social relational factor (ES=-0.29) had the greatest effect on psychological crises. The effects size of the overall risk variables was 0.48. In the risk factors, the physical factor (ES=0.61) had the greatest effect on psychological crises, followed by the psychological factor (ES=0.53), and cognitive and behavioral factor (ES=0.10). Conclusion: An intervention program is needed to strengthen the defensive factors and reduce the risk factors for psychological crises of Korean middle aged adults.
