The purpose of the this study is served the basic data for finding injury causes, preventing sports injury. We investigated the pre-study journals, experiment papers, text books. This study was analyzed swimming, volleyball, baseball, badminton players who occur shoulder damage especially. Most shoulder injuries was the Rotator cuff tear due to decreased scapular movement and stability, SLAP(Superior laborum anterior to posterior), impingement syndrome(Impingement Syndrome), Tendinitis, Supra scapular Nerve Injury, Medial or Lateral Epicondylitis. Most effective shoulder rehabilitation methods is the Sera-band movement, Therapeutic massage, stretching, isometric exercises, relaxation exercises.

Gastrointestinal tract of chicken is densely populated with microorganisms which have close interactions with ingested feed and the host. The gut microbiome plays an important role in nutrient digestion, pathogen inhibition and gut-associated immunity. In return, the host provides a permissive habitat and nutrients for bacterial growth and colonization. Gut microbiome can be affected by feed, and different dietary interventions are used by poultry producers to enhance the growth and reduce the risk of enteric infection by pathogens. For the effective and constant pathogen control, combination of pre-harvest, harvest and post-harvest measures should be considered comprehensively. The control measures would be most effective at farm level where the contamination initiates. Transmission of pathogen from feed origin to the live poultry and finally to the products was proven already. To control bacteria in the feed ingredients and formula feed, thermal processing, irradiation or chemical treatment may be applied. Various feed additives replacing antibiotic growth promoters(AGPs) are introduced to control pathogens and improve gut health in poultry production system since AGPs have been banned in some countries. There also exist extensive interactions among members of the gut microbiome. A comprehensive understanding of these interactions will help develop new dietary or managerial interventions that can enhance feed efficiency, maximize productivity, and protect birds from enteric diseases caused by pathogenic bacteria.

PURPOSE : This study is a systematic literature review carried out to provide the most efficient treatment method by comparatively analyzing and considering the existing previous papers on shoulder diseases that cause shoulder pain. METHOD : The research papers were published by December 2022, and a literature search was conducted using the electronic databases RISS, KISS, SCIENCE ON, DBpia, and Google Scholar. Search terms include 'adhesive capsulitis', 'rotator cuff', 'shoulder impingement syndrome', 'myofascial pain syndrome', 'calcific tendonitis', 'shoulder instability', and 'intervention', and 58 articles were included. It became. 9 studies were adhesive capsulitis, 10 studies were rotator cuff, 15 studies were shoulder impingement syndrome, 9 studies were myofascial pain syndrome, 5 studies were calcific tendinitis, and 10 studies were shoulder instability. RESULT : As a result of this study, the PNF technique was confirmed as an effective treatment for adhesive capsulitis, and joint mobilization techniques (mulligan, Spencer technique, Kaltenborn) were also suggested as effective treatments. For rotator cuff tear, elastic band resistance exercise, isometric exercise, and trunk muscle strengthening exercise combined with concave humeral joint mobilization and stretching are applied as an early acceleration protocol. As an independent exercise program, a program including stretching and strengthening exercise, shoulder chest It is suggested to apply exercise, spine movement exercise. For shoulder impingement syndrome, stabilization exercise, strengthening exercise, and manual therapy techniques are added to the exercise, suggesting that an intervention method is an effective treatment method for shoulder impingement syndrome. For myofascial pain syndrome, it is proposed to apply stretching and stabilizing exercises to maintain normal function for a long period of time after removing trigger points by applying ischemic compression therapy and extracorporeal shock waves. For calcific tendonitis, it is suggested to apply kinesio taping after performing extracorporeal shock waves in the shoulder hyperextension and medial rotation posture. Strengthening of the stabilizing muscles was confirmed as an effective treatment for shoulder joint instability, and McConnell taping was also effective in the mobility and stability of the shoulder blade. PNF manual resistance technique has also been suggested as an effective treatment. CONCLUSION : The results of this study mainly consisted of shoulder stabilization exercise, muscle strengthening exercise, and electrical therapy as interventions for shoulder pain, and provided evidence for physical therapy for shoulder pain, but additional research is needed. Evidence must be provided.

Recently, with the development of information and communication, a huge amount of data has been produced, and the use of predictive analysis to extract valuable information and predict phenomena by using and analyzing the produced data has become important. If this predictive analysis is used, it is better to enter the data that performed feature engineering than to enter the original data when inputting data into the machine learning algorithm. However, the data that performed feature engineering differs from the original data, limiting the use of data information in describing the predicted results of machine learning algorithms. To overcome these limitations, this paper proposes a visualization function that maps the original data and the data that performed feature engineering to the sankey diagram. Unlike traditional visualizations, this study develops visualizations that emphasize the process of changing data so that visualizations can identify which variables are important in the machine learning forecast results and which feature engineering is effective. The developed visualization was validated by finding out what variables and feature engineering are effective in predicting housing prices in Boston housing price data.

The existing insurance claim detection system is a method of deriving a rule based on the experience and knowledge of the inspectors about the insurance case charged based on the business rule. And it is divided into the subject rule to be investigated and the exclusion rule to be investigated. However, as insurance fraud becomes increasingly intelligent and sophisticated, it is necessary to continually update on new fraudulent claims patterns. In this paper, we classify the unfair claims patterns of unfair claims by labeling them and classify them as machine - learning based on the unfairness of new unfair claims through guidance learning about unfair claims. We propose intelligent fraud detection system.
