- A fundamental functionality of a Programmable Logic Controller (PLC) is to control and execute a set of operations. But a large part of the program code is more involved in supporting the user with concerns like alarm, HMI, communication, safety and manual control. Code related to these supporting concerns is often tangled with operation execution code, the core concerns, which makes it hard to reuse.This paper describes a method to reuse code and functionality when developing PLC programs and code libraries. The method proposes that core concerns are planned with a software tool called Sequence Planner, and the supporting concerns are integrated into the core concerns with a tool based on aspect-oriented programming.

Maximal strength in one leg squat correlates with acceleration capacity and agility
- 2010

Konferensbidrag (refereegranskat)abstract
- INTRODUCTION: In many intermittent team sports capacities such as speed, agility and explosiveness are important for performance and are evaluated by sprint-, agility- and strength tests. Earlier studies have shown strong correlations between strength in the two leg squat exercise and sprint performance in various distances but not in sprint performance in agility. Studies evaluating squat strength predominantly perform tests on two legs even when they test athletes involved in intermittent sports where sprinting and agility are common features. Thus, the purpose of this study was to investigate the correlation between maximal strength in a one leg squat (Bulgarian split squat) and acceleration capacity in various sprint distances and agility.METHODS: The test group consisted of 19 men (mean age 24 ± 2 years ) with experience in intermittent team sports. Acceleration capacity was assessed by sprint tests at 5, 10 and 20 meters and agility was evaluated using the zigzag agility test. The timing was made using photocells (Muscle lab,Ergotest Technology,Norway). The Bulgarian split squat was performed in a smith machine with the barbell on the shoulders to a depth of 110 degrees between tibia and femur.RESULTS: The results show significant correlation between maximal strength in the Bulgarian split squat and sprint capacity in the 5 and 10 meter sprint test (Rp= -0,56; p<0.01) as well as the agility test. Maximal strength relative to bodyweight showed significant correlation with the 5 and 20 meter sprint (Rp=-0,62; p< 0,01) as well as the agility test. The zigzag agility test also showed significant correlation between all distances in the sprint tests (p<0.01).CONCLUSION: The results from this study show that there maximal strength in one leg correlate significantly with both acceleration capacity and agility. Implementing one leg exercises in the strength and conditioning routine can be useful for athletes in intermittent sports wanting to improve agility and short sprinting capacity. Further implications is that the Bulgarian split squat could be a more functional test for agility performance than the squat on two legs which predominantly is being used today.

- The aim of the study was to evaluate the Swedish medical systems response to a mass casualty burn incident in a rural area with a focus on national coordination of burn care. Data were collected from two simulations of a mass casualty incident with burns in a rural area in the mid portion of Sweden close to the Norwegian border, based on a large inventory of emergency resources available in this area as well as regional hospitals, university hospitals and burn centres in Sweden and abroad. The simulation system Emergo Train System (R) (ETS) was used and risk for preventable death and complications were used as outcome measures: simulation I, 18.5% (n = 13) preventable deaths and 15.5% (n = 11) preventable complications; simulation II, 11.4% (n = 8) preventable deaths and 11.4% (n = 8) preventable complications. The last T1 patient was evacuated after 7 h in simulation I, compared with 5 h in simulation II. Better national coordination of burn care and more timely distribution based on the experience from the first simulation, and possibly a learning effect, led to a better patient outcome in simulation II. The experience using a system that combines both process and outcome indicators can create important results that may support disaster planning.
