Una banca dati 3D per il recupero e la valorizzazione del sito di San Michele Arcangelo Olevano sul Tusciano (Salerno)
No full textAlong the Picentini mountains slopes the Mt. Raione houses the entrance of San Michele Archangel cave. The place was used since the Neolithic period but the first historical data are linked to the IX siècle when it became a natural shelter for the bishop Pietro and, later, venue of pilgrimage. Due to the presence into the cave and its branches of bizantinian frescos, a church and some Martiryas (little chapels) with small courtyard the sanctuary is an unique example of important religious cave in Italy.
Recently, an archaeological campaign found out interesting ceramics objects such as the medieval ceramic Forum Ware made by roman traditions.
Extraordinary ancient music instruments, the Tibiae, were also found into the cave: they were made carving shinbones and then used as flutes by local inhabitants in ritual ceremonies.
After a joint effort of the Soprintendenza per i Beni Architettonici e per il Paesaggio, il Patrimonio Storico, Artistico e Demoetnoantropologico per le Province di Salerno e Avellino and the centre DIAPReM (Development of Integrated Automatic Procedures for Restoration of Monuments) of the Department of Architecture of the University of Ferrara, laser scanning integrated technologies were used in order to obtain a first survey aiming to show the huge quality of the site trough a complete documentation action.
The research project was finalized to give a strong base for the restoration and valorisation of the San Michele Site and the surrounding landscape; in the meanwhile it was a good opportunity to verify an integrated survey process in a low accessibility area in order to evaluate:
1 – the feasibility level of a such extreme condition technological survey;
2 – the instrumental acquisition degree of definition in relations to the morphometric level
of detail;
3 – how the survey could help to the configuration of a comparative model aiming to show
the degradation process and the loss or modification of the extraordinary architectural
and artistic heritage;
4 – how the morphometric database could be enquired in order to define further scenarios
of conservation and valorisation of the site.
The survey started with the main branch of the cave where a laser scanner Leica HDS 3000 (based on a time-flight technology which allow data collection of big volumetric complexes acquiring circa 1000 points per second with an accuracy of 6 mm) was used to obtain the needed information.
The three-dimensional data were then integrated by a topographic survey to realize a model made of 55.000.000 acquired points by the which was possible to drawn up the cave plans, sections and façades and a scaled plaster model.
The output will be useful to build a structured collection of records organized on several layers thought for information exchange, divulgation and for the realisation of revitalization project of this extraordinary site
A comparison of physiological responses during a CPR exercise on treadmill and a low impact aerobic dance lesson
No full textPURPOSE: Therefore our purpose was to investigate the differences of physiological responses between two aerobic exercises: Constant Pulse Training (CPR) and low impact aerobic routine (LIA) in order to understand if LIA fits the needs of overweight subjects in terms of energy substrate utilization.
METHODS: Six overweight female underwent a V'O2max incremental submaximal test (Quark b2, Cosmed, Italy). Oxygen uptake (V'O2) and heart rate (HR) were used to draw V'O2/HR relationship. Each subject also took part in two training sessions carried out over alternate days: A) CPR training on treadmill at 65%, 70% and 60% of HRmax for 10, 30 and 5 min respectively; B) LIA routine consisting of warming up phase (10 min), aerobic phase (30 min), cooling down phase (5 min). During both sessions the following parameters have been continuously monitored (K4b2, Cosmed, Italy): HR, V'O2, respiratory exchange ratio (RER).
RESULTS: Results are referred to the whole training session.
If we consider the correlation between HR and V'O2, both expressed as percent values of the maximum, linear regression line among HR and V'O during CPR never overlaps the one during LIA.CONCLUSION: Both exercise modes seem to lie in the aerobic metabolism. However energy expenditure (EE) of LIA is higher than CPR, while the relative amount of CHO is significantly higher. This should be took into account when fat burning exercises are prescribed. Besides HR seems to correlate with V'O2 (according with ACSM statement) in CPR, while the same does not occur during LIA. Therefore, HR is a reliable index of the exercise intensity during CPR training, but it could overestimate V'O2 (and EE) during LIA routine

One-year Changes in Activity and in Inactivity Objectively Measured Among Overweight and Obese Children
No full textParticipation in physical activity (PA) during childhood can help to reduce the onset of risk factors associated with ill health. Seasonal influences play a large role in determining PA behaviors. Lack of information about overweight (OW) and obese (OB) children PA and sedentary (SED) behaviors, evaluated during a whole year, has made it difficult to assess appropriate interventions. PURPOSE: The aim of this study was to objectively measure PA behavior in a sample of 6 to 14 yr-old children in order to investigate seasonal and weekly differences in PA and SED habits. METHODS: 18 OW and OB children (OW (n=8): age 10,8±1,2 yr; BMI, 21,9±1,4 kg/m2; OB (n=10): age 10±2,1 yr; BMI 25,6±3,2 kg/m2) were monitored during a whole week 4 times in a year with a Actiheart (AH) monitor (Cambridge Neurotechnology, UK), inferring time spent in sedentary (SED, 3 METs) intensity. Data presented provide a minimum of four days of 10-h valid recording per week (at least 1 weekend day is included). A Repeated measure ANOVA was used to analyse data and significance was set at p<0,05. RESULTS: A non significant seasonal difference was detected for time spent in MVPA (spring 129,7±82,4; summer 106,7±76,9; fall 93,5±72; winter 82,7±60,3 min/day) causing, on the contrary, a significant seasonal difference in activity energy expenditure (AEE: spring 660,5±188,3; summer 540,8±132,1; fall 538,9±152,5; winter 482,2±136,2 kcal/day; p<0,05). A significant seasonal difference was found in SED behavior (spring 436,9±95,6; summer 389,7±81,2; fall 479,2±93,3; winter 473,8±80,1 min/day; p<0,05). No significant differences appeared between weekly and weekend days (MVPA: weekdays 100,7±70,1; weekend 110,1±87,8; SED: weekdays 460,6±94,8; weekend 431,6±118,9 min/day). Besides, OW appeared to be more active than OB children (MVPA: OW 122,8±86,2; OB 87,3±60,8 min/day, p<0,05). CONCLUSIONS: The main finding of this study is that AH data, taking activity into account (without loosing water sports or activity), indicate that for OW and OB children activity levels are highest in spring, drop in summer and reach the lowest point in winter. Besides, children do not result to be more active on weekly days than during the weekends as reported by some authors.

Comparison of activity monitors accuracy to estimate energy expenditure of daily living activities
No full textAccurate assessment of the total amount of physical activity (PA) or the energy expenditure (EE) in free living condition is a big challenge. A priority has been placed on the study of valid and reliable measures for all levels of PA. New technologies are available for objectively measuring PA and inferring EE: the Actiheart -AH-(Cambridge Neurotechnology, UK) and the SenseWear Pro2 ArmbandTM -SWA-(BodyMedia, USA) are an example of these new devices.
PURPOSE The purpose of the present study was to examine the validity of these two new devices during light (<3 METS) to moderate (3-6 METS) and vigorous (>6 METS) intensity daily living activities in laboratory and feld settings.
METHODS: 8 physically active women volunteered to participate in the study and performed in two separate days different activities: resting, occupation, housework, conditioning and recreation. Oxygen consumption was measured continuously throughout the routine by indirect calorimetry -IC- (K4b2, Cosmed, Italy) and participants wore the Actiheart on the chest and the Armband on the right arm for simultaneous estimation of EE (METS). RESULTS The combined AH model (Branched model: activity counts+HR) had the strongest relationship with PAEE (r=0785, p<0001) compared with those from the single-measure models (r=.748 and .719, p<0001 for the activity model and the HR model respectively), so that we only used this equation model to compare data with SWA and IC. The two analyzed methods were highly correlated with IC (AH r=.785 and SWA r=.795, p<0001) even if PAEE expressed in METS resulted significantly different for both devices (p<0.001 for AH and p<0.001 for SWA). The positively correlated errors with measured PAEE in the plots of both AH and SWA models indicate a systematic error in these equations (mean difference between methods= AH 1.52±2.38, SWA -0.11±2.48; 95% limits of agreement= AH -3.24 to 6.28, SWA -5.07 to 4.85). On the contrary the explained variances from the AH were lower if light intensity exercises are considered. CONCLUSION The AH provides reliable estimates of EE for light intensity activities; on the contrary it underestimates moderate and vigorous activities. The SWA has a lower systematic error in moderate and vigorous exercises. Both devices can provide a valid measure of the time spent in various intensity categories
