Dynamic Analysis of Splash-zone Crossing Operation for a Subsea Template
Authors: Amer Adham M. , Li Lin , Zhu Xinying
Published: October 2022

Subsea templates are steel structures used to support subsea well components. Normally, offshore crane vessels are employed to install them to the target location on the seabed. Crossing the splash-zone during the lowering of a subsea template is considered the most critical phase during the installation due to slamming loads and needs to be studied to provide the operational weather criterion during the planning phase. In this study, dynamic response analysis has been carried out to evaluate the allowable sea states for the plash-zone crossing phase of the subsea templates. The numerical model of the lifting system, including the crane vessel and the subsea template, is firstly built in the state-of-the-art numerical program SIMA-SIMO. Then, dynamic analysis with time-domain simulations is carried out for the lifting system under various sea states. The disturbed wave field due to the shielding effects from the installation vessel is considered when calculating the hydrodynamic forces on the template. Statistical modelling of the dynamic responses from different wave realizations is used to estimate the extreme responses of various sea states. The application of the generalized extreme value distribution and Gumbel distribution in fitting the extreme responses is discussed. Moreover, the influence of the shielding effects from the vessel, as well as the influence of the changing size of the suction anchor on the hydrodynamic responses and the allowable sea states are studied.

The clustering process uses the SOM algorithm, and the data is taken from the website data.go.id/dataset. Data is processed in order to show which fish yields are small, medium and large. The processing process uses variable types of fish, years and results of sea fish that are stored in Excel files and then processed using Matlab. The results show that there are fish species that are classified as low and moderate clusters, namely shrimp, squid, serimping, grouper, turmeric, and ray species. The types of fish that enter the cluster and many are Tigawaja. The types of fish that enter the medium cluster are Beloso, Pihi, Pepetek, and those who enter the low cluster are 18 fish species, while those who enter the low, medium and many clusters are Petek.

Published: October 2022

Chorangiomas are benign non trophoblastic vascular neoplasm arising from primitive chorionic mesenchyme. It isthe most frequent placental tumor occurring in 1% of pregnancies. Giant chorangioma(>5 cms) exemplifies adversefetal and maternal outcomes. Chorangiomas need to be differentiated from chorangiosis, chorangiomatosis,inflammatory myofibroblastic tumor, leiomyomas, placental infarcts and chorangiocarcinomas. USG is thegold standard for diagnosis of chorangioma. Color Doppler is benificial in differentiation of chorangioma fromdegenerated uterine leiomyoma or associated other placental tumors. Therapeutic interventions of chorangiomais controversial like draining excessive amniotic fluid or surgical intervention like laser coagulation and interstitiallaser therapy. All placentas need to be examined histopathologically for confirmation of diagnosis and todifferentiate from other tumors.
A Quasi Experimental Study to Evaluate the Effectiveness Of Pursed Lip Breathing Exercise on Reduction of Dyspnea Among Chronic Obstructive Pulmonary Disease Patients in Selected Hospital in Panipat, Haryana
Authors: Rachna Singh
Published: October 2022

Chronic Obstructive Pulmonary Disease (COPD) is a progressiveinflammatory disease characterized by chronic obstruction in the peripheral bronchus and pulmonary emphysema. The disease is disabling with symptoms such as chronic cough, phlegm, wheezing, shortness of breath and increased infections of the respiratory passage. Changes in the lungs result in mucus hyper secretion, dysfunction of the cilia, airflow limitation and hyper inflation of the lungs, gas exchange abnormalities, pulmonary hypertension and cor pulmonale. Persons with COPD are greatly under estimated because the disease is usually not diagnosed until it is moderately advanced .Patients usually seek medical help when they have an acute respiratory infection, with dyspnea being the main concern. Dyspnea is often progressive, and initially occurs with exertion, gradually interferes with daily activities and in late stages dyspnea may be present at rest also. The person becomes more of a chest breather, relying on the intercostals and accessory muscles rather than effective abdominal breathing.The objective of the study was, to assess the breathing pattern before and after pursed Lip breathing exercise among chronic obstructive pulmonary disease patients in control and experimental group. To evaluate the effectiveness of Pursed lip breathing exercise on the reduction of Dsypnea among chronic obstructive pulmonary disease patients in experimental group. To find out the association between the breathing pattern with selected demographic variables in the control and experimental group.

Development of a Virtual Reality Nursing Assistance System to Positively Enhance Rectal Medication Adherence in Children
Authors: Wei Kai Liou  , Pao Ju Chen
Published: October 2022

Children may feel uneasy, anxious and fearful when faced with an invasive procedure because they cannot understand the reason for their illness and they fear the destruction of the integrity of their bodies. In rectal drug delivery (the use of anal suppositories), children often move their hips and cry during the procedure, which may cause the suppository to inadvertently break, slip out, or be misplaced in the vagina. In order to find to a solution to the clinical issue, this study focuses on the application of virtual reality in developing a VR nursing assistance system that can be used in clinical practice with only ordinary cell phones and simple VR headsets, called “Little Hero Saves the Earth”. This system allows children to immerse themselves in the plot of a story through a first-person perspective (as the “little hero”). When the little hero needs to have the superpower rocket fitted (what the child perceives in the first-person perspective), the nurse places the child in a side-lying position before inserting the suppository (superpower rocket) in sync with the plot. This serves to reduce the child’s fear of invasive procedures, encourage the child to think of anal suppositories in a positive way, and lead to a sense of autonomy and accomplishment in the child, thus creating a positive, successful experience.
