IMPLEMENTATION OF A RECORDS SYSTEM FOR TECHNICAL DOCUMENTS AND DRAWINGS - CASE OY NAUTOR AB
The background of the thesis was a wide scale IT systems renewing project conducted by Oy Nautor Ab between mid 2005 and end of 2007. Different ERP systems, among other things, were being assessed and the chosen ERP system was accompanied by a 3rd party document management system, PDMWorks Enterprise, as a complement to the ERP system.
This thesis describe the implementation of the document handling system, how the requirements of this new system were defined, how the system was configured and finally deployed for production use in a pilot project. The new document handling system was to manage all technical documentation including 2D drawings and 3D CAD data related to the company’s products, i.e. luxury offshore sailing yachts between 50 and 130 foot in length, as well as other documentation of a more administrative type. The scope of the thesis was limited to the technical documentation and more specific to the handling of 2D drawings and 3D CAD data.
The requirements for the new system were found via multi-disciplinary project meetings and workshops together with representatives from the Finnish PDMWorks Enterprise reseller, CadON Oy. These requirements were then configured into the system by defining the document metadata model, folder structures, workflows and user access rights. The configured system was then tested for production use in the new Swan 60 development project and after six months a survey was conducted amongst the designers working in the system.
The results from the pilot project survey showed that although many of the Oy Nautor Ab specific adoptions and configurations seemed to work well the PDMWorks Enterprise environment as a whole seemed to be too unstable for production use at Oy Nautor Ab.Bakgrunden till examensarbetet var att Oy Nautor Ab bedrev ett omfattande förnyelseprojekt av företagets IT system mellan mitten av 2005 till slutet av 2007 där bland annat ERP systemet var under utredning. Med det valda ERP systemet följde ett tredje parts dokument hanteringssystem, PDMWorks Enterprise, vars uppgift var att komplettera det valda ERP systemet.
Examensarbetet beskriver hur kravställningen för det nya dokumenthanteringssystemet söktes, konfigurerades samt lanserades och testades. Det nya dokumenthanteringssystemet var tänkt att kunna hantera hela företagets dokumentation inklusive produkternas, havsgående lyx segelbåtar mellan 50 och 130 fot i längd, tekniska dokumentation. Examensarbetet begränsades till att gälla enbart teknisk dokumentation och specifikt hanteringen av 2D ritningar och 3D CAD filer.
Kravställningen på det nya systemet söktes via projektmöten mellan olika discipliner och funktioner inom företaget samt arbetsmöten tillsammans med representanter från den finska återförsäljaren av PDMWorks Enterprise, CadON Oy. Kravställningen användes sedan vid konfigureringen av systemets metadata, mapp strukturer, processflöden och styrningen av användarrättigheterna. När systemet konfigurerats klart testades det i produktionsmiljö i ett pilotprojekt, utvecklingen av den nya Swan 60 båtmodellen, och efter ca 6 månaders användande skickades en utvärderingsblankett ut till användarna i pilot projektet.
Resultatet av utvärderingsblanketten visade att även om konfigureringen av nya systemet verkade fungera väl visade sig PDMWorks Enterprise systemet som helhet vara för ostabilt för att kunna användas i produktionssyfte vid Oy Nautor Ab

Cardiac Autonomic Neuropathy as a Predictor of Deterioration of the Renal Function in Normoalbuminuric, Normotensive Patients with Type 2 Diabetes Mellitus
Our study was performed to determine whether cardiac autonomic neuropathy can predict deterioration of the renal function in normoalbuminuric, normotensive people with type 2 diabetes mellitus (DM). One hundred and fifty-six normoalbuminuric, normotensive people with type 2 DM were included in our retrospective longitudinal study. We categorized normal patterns, early patterns, and definite or severe patterns according to the results of the cardiac autonomic function test. Of 156 patients included, 54 had normal patterns, 75 had early patterns, 25 had definite or severe patterns, and 2 had atypical patterns. During a median follow-up of nine years, glomerular filtration rates (GFR) remained stable in the normal and early pattern groups (mean changes, 4.50% and 0.77%, respectively) but declined in those with definite or severe patterns (mean change, -10.28%; p=0.047). An abnormal heart response to the deep breathing test of the cardiac autonomic function tests was an independent predictor of GFR decline. Our data suggest that cardiac autonomic neuropathy, especially with a definite or severe pattern, might be associated with a subsequent deterioration in renal function in normoalbuminuric, normotensive people with type 2 DM
Evaluating Option Pricing Models
This study evaluates three different time units in option pricing: trading time, calendar time and continuous time using discrete approximations (CTDA). The CTDA-time model partitions the trading day into 30-minute intervals, where each interval is given a weight corresponding to the historical volatility in the respective interval. Furthermore, the non-trading volatility, both overnight and weekend volatility, is included in the first interval of the trading day in the CTDA model. The three models are tested on market prices. The results indicate that the trading-time model gives the best fit to market prices in line with the results of previous studies, but contrary to expectations under non-arbitrage option pricing. Under non-arbitrage pricing, the option premium should reflect the cost of hedging the expected volatility during the option’s remaining life. The study concludes that the historical patterns in volatility are not fully accounted for by the market, rather the market prices options closer to trading time
Volatility Smile Dynamics in Scenario Analysis
The objective of this paper is to suggest a method that accounts for the impact of the volatility smile dynamics when performing scenario analysis for a portfolio consisting of vanilla options. As the volatility smile is documented to change at least with the level of implied at-the-money volatility, a suitable model is here included in the calculation process of the simulated market scenarios. By constructing simple portfolios of index options and comparing the ex ante risk exposure measured using different pricing methods to realized market values, ex post, the improvements of the incorporation of the model are monitored. The analyzed examples in the study generate results that statistically support that the most accurate scenarios are those calculated using the model accounting for the dynamics of the smile. Thus, we show that the differences emanating from the volatility smile are apparent and should be accounted for and that the methodology presented herein is one suitable alternative for doing so
