  • The increasing number of credit card fraud cases has become a considerable problem since the past decades. This phenomenon is due to the expansion of new technologies, including the increased popularity and volume of online banking transactions and e-commerce. In order to address the problem of credit card fraud detection, a rule-based approach has been widely utilized to detect and guard against fraudulent activities. However, it requires huge computational power and high complexity in defining and building the rule base for pattern matching, in order to precisely identifying the fraud patterns. In addition, it does not come with intelligence and ability in predicting or analysing transaction data in looking for new fraud patterns and strategies. As such, Data Mining and Machine Learning algorithms are proposed to overcome the shortcomings in this paper. The aim of this paper is to highlight the important techniques and methodologies that are employed in fraud detection, while at the same time focusing on the existing literature. Methods such as Artificial Neural Networks (ANNs), Support Vector Machines (SVMs), naïve Bayesian, k-Nearest Neighbour (k-NN), Decision Tree and Frequent Pattern Mining algorithms are reviewed and evaluated for their performance in detecting fraudulent transaction.

  • Sentiment analysis is a method used to comprehend feelings, opinions, and attitudes in text, and it is essential for evaluating consumer feedback and social media posts. However, creating sentiment dictionaries, which are necessary for this analysis, is complex and time-consuming because people express their emotions differently depending on the context and domain. In this study, we propose a new method for simplifying this procedure. We utilize syntax analysis of the Korean language to identify and extract sentiment words based on the Reason-Sentiment Pattern, which distinguishes between words expressing feelings and words explaining why those feelings are expressed, making it applicable in various contexts and domains. We also define sentiment words as those with clear polarity, even when used independently and exclude words whose polarity varies with context and domain. This approach enables the extraction of explicit sentiment expressions, enhancing the accuracy of sentiment analysis at the attribute level. Our methodology, validated using Korean cosmetics review datasets from Korean online shopping malls, demonstrates how a sentiment dictionary focused solely on clear polarity words can provide valuable insights for product planners. Understanding the polarity and reasons behind specific attributes enables improvement of product weaknesses and emphasis on strengths. This approach not only reduces dependency on extensive sentiment dictionaries but also offers high accuracy and applicability across various domains.

  • Clinical and molecular phenotypes of asthma are complex. The main phenotypes of adult asthma are characterized by eosinophil and/or neutrophil cell dominant airway inflammation that represent distinct clinical features. Upper and lower airways constitute a unique system and their interaction shows functional complementarity. Although human upper airway contains various indigenous commensals and opportunistic pathogenic microbiome, imbalance of this interactions lead to pathogen overgrowth and increased inflammation and airway remodeling. Competition for epithelial cell attachment, different susceptibilities to host defense molecules and antimicrobial peptides, and the production of proinflammatory cytokine and pattern recognition receptors possibly determine the pattern of this inflammation. Exposure to environmental factors, including infection, air pollution, smoking is commonly associated with asthma comorbidity, severity, exacerbation and resistance to anti-microbial and steroid treatment, and these effects may also be modulated by host and microbial genetics. Administration of probiotic, antibiotic and corticosteroid treatment for asthma may modify the composition of resident microbiota and clinical features. This review summarizes the effect of some environmental factors on the upper respiratory microbiome, the interaction between host-microbiome, and potential impact of asthma treatment on the composition of the upper airway microbiome.

  • Immune checkpoint blockade targeting PD-1 and PD-L1 has resulted in unprecedented clinical benefit for cancer patients. Anti-PD-1/PD-L1 therapy has become the standard treatment for diverse cancer types as monotherapy or in combination with other anticancer therapies, and its indications are expanding. However, many patients do not benefit from anti-PD-1/PD-L1 therapy due to primary and/or acquired resistance, which is a major obstacle to broadening the clinical applicability of anti-PD-1/PD-L1 therapy. In addition, hyperprogressive disease, an acceleration of tumor growth following anti-PD-1/PD-L1 therapy, has been proposed as a new response pattern associated with deleterious prognosis. Anti-PD-1/PD-L1 therapy can also cause a unique pattern of adverse events termed immune-related adverse events, sometimes leading to treatment discontinuation and fatal outcomes. Investigations have been carried out to predict and monitor treatment outcomes using peripheral blood as an alternative to tissue biopsy. This review summarizes recent studies utilizing peripheral blood immune cells to predict various outcomes in cancer patients treated with anti-PD-1/PD-L1 therapy.

The Literature Review on the Relation between the Modulation of Arousal and the Suck/Swallow/Breathe(SSB) Synchrony (각성조절과 빨기/삼키기/숨쉬기의 조화(Suck/Swallow/Breathe Synchrony)와의 연관성에 관한 고찰)

  • The suck/swallow/breathe(SSB) synchrony, serving as the earlist primary motor mechanism, is the rhythmical, coordinated pattern of sucking, swallowing and breathing. The development of an intact SSB is an important precursor for further sensorimotor and cognitive development including speech and language development, state regulation, postural control, feeding, eye/hand coordination and social/emotional development. Arousal means a neurological mechanism for preparing one's body to orienting stimulus. Its levels are regulated with an interaction of the reticular formation, the limbic system, the hypothalamus and the autonomic nervous system. General strategies such as blowing, sucking, chewing, munching and licking to effectively modulate arousal state are related to SSB. The SSB synchrony is an important treatment principle for children with sensory integration disorder and problems with the modulation of arousal. The purpose of this article is to review concepts of SSB synchrony and the underlying relation between the modulation of arousal and SSB synchrony.

  • Objectives: Several practice guidelines recommended both medication and behavior modification to control hypertension. The objective of this study was to analyze ambulatory care utilization pattern and related factors. Methods: A retrospective cohort study was conducted among 45,267 new users who initiated treatment with hypertensive drugs in 2003. Korean National Health Insurance Claims Data was used to study the medical care utilization behavior and related factors after treatment initiation for up to four years. Taking prescription was considered as medical care utilization. Results: More than 20% of patients discontinued visiting physicians for prescription after initiating antihypertensive drug therapy. The average number of institutions visited by patients was about 1.3 annually. Clinic was the most frequently visited institution by patients. In GEE analysis, probability of continuous visit one institution after initiating antihypertensive drug treatment increased in patients who were women, old, have comorbidity, visited clinic or hospital mainly in previous year. Conclusions: Young hypertensive male patients who have no major comorbidity showed high possibility to discontinue medical service utilization. It is necessary to educate these targeted patients about importance of hypertension management in early stage after treatment initiation.

  • Objectives: The purpose of this study was to evaluate the achievements of Ryodoraku and to suggest new diagnostic ideas. Methods: A search of six Korean databases and one Japanese was performed using the terms such as Ryodoraku, diagnosis, foreigner, etc. and the search results classified and summarized. Results: From the initial search results, 21 Korean papers and 26 Japanese papers were selected and classified into 4 categories, that is, classification by pattern, classification by physiological limit, classification by setting various sections using the average Ryodoraku score, and classification by formula. Conclusions: Each of the 4 methods has its own benefits; however, it is hard to find disease-specific common characteristics from the Ryodoraku diagnostic values with the methods. Further studies which use the number of Pyesaek and Gyeokcha are necessary.
