Background and Objectives The study reports on the clinical experience of repairing white-eyed orbital blow out fracture through a retrospective study of various incidences of white-eyed orbital blow out fracture that resulted in different treatment methods and outcomes.Subjects and Method A retrospective study was performed on 22 patients with white-eyed blowout fracture who underwent operation between March 2009 and June 2019 at our clinic. Patients were divided into 2 groups by age: 6 to 12 and 13 to 18. A review of medical records included demographic data, cause of injury, preoperative symptoms, trauma to operation time and surgical outcomes including improvement of postoperative ocular symptoms and complications.Results The study population included 20 males and 2 female patients ranging from 6 to 18 years (mean, 14.2 years) of age. Fifteen of 21 patients with diplopia or limitation of eyeball movement showed a complete improvement of symptoms after surgery and 6 (28.5%) had remaining symptoms. One patient had no ocular symptom, but had oculocardiac reflex including nausea and vomiting. Two cases were re-operated due to adhesion of graft material. There was one sinus infection related to the implant.Conclusion This study shows that early reconstruction and release of incarcerated muscle within 5 days after trauma for white-eyed blowout fracture gives successful result that does not accompany major complications. All of the 22 patients who were operated for white-eyed blowout fractures had successful results.

In ancient times, trade was carried out by barter. With the use of money and similar means, the concept of financial instruments emerged. Financial instruments are tools and documents used in the economy. Financial instruments can be foreign exchange rates, securities, crypto currency, index and funds. There are many methods used in financial instrument forecast. These methods include technical analysis methods, basic analysis methods, forecasts carried out using variables and formulas, time-series algorithms and artificial intelligence algorithms. Within the scope of this study, the importance of the use of artificial intelligence algorithms in the financial instrument forecast is studied. Since financial instruments are used as a means of investment and trade by all sections of the society, namely individuals, families, institutions, and states, it is highly important to know about their future.  Financial instrument forecast can bring about profitability such as increased income welfare, more economical adjustment of maturities, creation of large finances, minimization of risks, spreading of ownership to the grassroots, and more balanced income distribution. Within the scope of this study, financial instrument forecast is carried out by applying a new methods of Long Short Term Memory (LSTM), Recurrent Neural Network (RNN), Convolutional Neural Network (CNN), Autoregressive Integrated Moving Average (ARIMA) algorithms and Ensemble Classification Boosting Method. Financial instrument forecast is carried out by creating a network compromising LSTM and RNN algorithm, an LSTM layer, and an RNN output layer. With the ensemble classification boosting method, a new method that gives a more successful result compared to the other algorithm forecast results was applied. At the conclusion of the study, alternative algorithm forecast results were competed against each other and the algorithm that gave the most successful forecast was suggested. The success rate of the forecast results was increased by comparing the results with different time intervals and training data sets. Furthermore, a new method was developed using the ensemble classification boosting method, and this method yielded a more successful result than the most successful algorithm result.

In this paper, A retrospective review was performed for all the patients who underwent surgery with the Goldman technique by the senior author from 2004 to 2009 for correction of the broad nasal tip. The clinical and pathologic findings of these patients were reviewed, and an independent observer evaluated the pre- and postoperative photos of the patients using five parameters: projection, rotation, symmetry, shape, and distance of the tip-defining points. The evaluation was performed using a scale of -1 to +1 for each of the five parameters. Of the 205 patients who underwent the technique, 115 (56%) were patients with broad tips, and 90 (44%) were patients with broad (boxy) tips. A total of 189 cases (92.2%) involved primary rhinoplasties, and 16 cases (7.8%) involved revision. During this period, complications were observed in five patients (2.4%), who underwent revision rhinoplasty with a successful result. The average score for the five parameters already mentioned for primary rhinoplasties according to the scale of -5 to +5 showed a significant postoperative improvement (score, +4.3). It implied that the cartilage rhinoplasty with Goldman technique is safe when performed by experienced surgeons and according to specific indications. This conclusion is indicated by the low rate of complications in the large series of patients in this study.

Pariksha is the tool used to explore knowledge regarding the span of life, potency and strength of the disease. Pariksha is also used as Pramana in Ayurveda. The concept of Dashvidha Pariskha is described in Ayurveda which is very much scientific in terms of understanding the duration of life, strength of person and disease. Treatment principles may vary from patient to patient depending on strength of the patient and morbidity of the disease. Many scattered references are found in Ayurvedic literature which lay stress on research namely “Pareeksha karino hi Kushal Bhavanti" and many synonyms of research are available viz. Eshana and Anveshana. Hence patient is to be examined in respect of Prakruti, Vikriti, Sara, Samhanana, Pramana, Satmya, Satva, Aahara shakti, Vyayama shakti and Vaya is Dashvidha Pariskha. Tenfold examinations should be done to understand the overview of patient condition in relation to disease Pariksha must be carried out scientifically in a systemic and planned way to get a successful result. It is very much essential that before any treatment one should have complete knowledge of Roga and Rogi Bala. Keywords: Roga Bala, Rogi Bala, Dashavidha Pariksha, Vyadhi, Swasta.

The Shodhana procedures are mainly divided into three phases known as Trividha Karma. Acharya Dalhana has clarified Trividha Karma in the context of Shodhana as Poorva Karma, Pradhana Karma and Paschat Karma. Samsarjana Krama is a special diet pattern which is followed as Paschat Karma after Samshodhana. After Samshodhana Karma the Atura Shareera will have reduced tolerance owing to the elimination of large quantities of Dosha and Mala from the body, leading to weakness and reduction in digestive fire. This can be corrected only by following proper Samsarjana Krama with respect to the Shuddhi attained by the Atura. Acharyas detailed the Samsarjana Krama for two Annakala with respect to the ancient time period in contrast to the present scenario, where we are following three Annakala. To get a successful result from the treatment the patient should follow all the 3 stages properly. Hence, here an attempt is made to modify the Samsarjana Krama chart for the present era with respect to classical information given by the Acharyas.

Schrödinger developed his famous equation from the standard wavelength. However, as demonstrated here, inside the atom, the electron does not move according to de Broglie-Einstein’s postulate λ = h/p, because the wavelength of the electron’s motion varies with the distance to the nucleus. Therefore, Schrödinger’s equation does not quantify the real electron’s motion in atoms. Here, the equation of a variable wavelength for electron motion inside atoms is introduced. The calculation, applied to the hydrogen atom, achieves energy level values very close to the experimental values. This successful result can provide a deeper understanding of the behavior of electrons in atoms and improve the fundamentals of quantum mechanics (QM). However, beyond the question concerning the postulate λ = h/p, two other fundamental principles may be missing in modern QM, and they are: an anisotropic space inside atoms and a motion of the electron through a helical trajectory.

The analysis and processing of ECG signals are a key approach in the diagnosis of cardiovascular diseases. The main field of work in this area is classification, which is increasingly supported by machine learning-based algorithms. In this work, a deep neural network was developed for the automatic classification of primary ECG signals. The research was carried out on the data contained in a PTB-XL database. Three neural network architectures were proposed: the first based on the convolutional network, the second on SincNet, and the third on the convolutional network, but with additional entropy-based features. The dataset was divided into training, validation, and test sets in proportions of 70%, 15%, and 15%, respectively. The studies were conducted for 2, 5, and 20 classes of disease entities. The convolutional network with entropy features obtained the best classification result. The convolutional network without entropy-based features obtained a slightly less successful result, but had the highest computational efficiency, due to the significantly lower number of neurons.

Using a digital camera to achieve a successful result requires from the user, first and foremost, to be familiar with the proper use of the medium and to have obtained basic knowledge of the principles of the art of photography. What is the result in those cases where the photographer either does not know the basic principles of photography or cannot apply them effectively in practice? Is the product considered a “failure” thus leaving photos with no clear and recognizable objects? This paper focuses on designing and implementing an applied educational intervention, themed on ”shaken” photos taken by preschoolers and using this material to create digital narratives. This case study examines "shaken" photos as an opportunity to develop imagination and creativity through photography.

Preoperative laryngoscopic examination of the airway informs general anaesthesia management and planning. However, the same glottic opening view cannot always be obtained during direct laryngoscopy of anaesthetised patients. In this case report, a patient underwent preoperative rigid laryngoscopy due to medical history, and no problems were anticipated in performing tracheal intubation; however, the direct laryngoscopic view was a Grade 4 on the Cormack-Lehane Scale after anaesthesia induction. A jaw thrust manoeuvre to facilitate fibreoptic-assisted nasotracheal intubation was not feasible. In order to compensate, a modified method of jaw thrust was implemented, where both thumbs were placed on the floor of the patient’s mouth, leading to a successful result. Safe airway management should be implemented with proper planning based on a careful preoperative evaluation.
