Modeling of stratosphere airship
The dynamics and kinematics model is very important for the analysis of stability, manipulation and control of stratosphere airship. A full modeling approach that includes the computation of aerodynamics of airship and the added mass for the nonlinear dynamics simulation of stratosphere airships is proposed in this paper. In this approach, the aerodynamics of airship is calculated based on a panel method, an engineering estimation and theory approach. A new numerical method for calculating added masses of airship is developed by using the CFD method. This model can simulate the motion of stratosphere airships quickly and accurately.
Numerical investigation for cooperative multi blimp system
This paper presents the numerical investigation on multi blimp motion using three dimensional computational 
fluid dynamic (CFD) approach. The cooperative flight configuration is important to reduce energy and improve the 
communication reliability within the group. Therefore, we examined the influence of drag and pressure force of 
cooperative configurations shape in several formations: vee, echelon, line and column. The use of different velocity is also 
presented to study the effect on a cooperative navigation process. The outcome of this analysis provides the optimal 
configuration for multi blimp operation. Based on the numerical results, the vee formation should be considered as the best 
cooperative configuration with low drag effect of drag coefficient and lift coefficient which offered good data overlapping.
Relationship between level of internet addiction and time management skills among nursing students.
PURPOSE
This study investigated nursing students' levels of internet addiction (IA) and time management (TM) skills.


DESIGN AND METHODS
This cross-sectional descriptive study was conducted with 400 nursing students of a university in Turkey. The data were collected using the Personal Information Form, IA Scale, and TM Inventory.


FINDINGS
The IA scale and TM inventory mean scores were 40.83 ± 14.81 and 81.34 ± 11.91, respectively. A significantly negative relationship between students' level of IA and TM skills was found (p <0.05).


PRACTICE IMPLICATIONS
The concept of effective time management should be used in interventions for promoting students' conscious internet use.
