In this dissertation, I present the results of a project which aim was to find out and try an effective model of independent curatorial project executable in small and medium cities in Portugal. The concept of Moving Curatorial Project ARTMAP is a result of theoretical research and reflection about municipal exhibition spaces and possibility of presentation of the contemporary art in these spaces. To test if this curatorial project is realizable and if there are conditions to continue it, a first trial was implemented in Aveiro. A curated international exhibition, entitled “A Poética do Visual" occupied two municipal and two private gallery spaces and brought together 111 artists from 25 different countries. The art event was carried out in collaboration with the Municipality of Aveiro and the University of Aveiro, and involved several private cultural spaces in the city. This first experience showed that there are all conditions for the presentation of contemporary art in small and medium size locations in Portugal, and for this project to be replicated in other regions of the country.

Pk-yritykset ovat nousseet merkittäväksi puheenaiheeksi viime vuosina niiden työllistävän vaikutuksen vuoksi. Iso osa uusista työpaikoista on syntynyt pk-yrityksiin eikä suuriin yrityksiin. Samalla kansainvälistymiskehitys on ollut aikamme suurimpia muutosvoimia, jotka vaikuttavat talouselämään. Kansainvälistymällä yritykset ovat saaneet uusia väyliä hankkia rahoitusta, laajentaneet ja monipuolistaneet asiakaskuntaansa ja hankkineet skaalaetuja. Kansainvälisyys aiheuttaa haasteita yritysten taloudelliselle raportoinnille, joten pk-yrityksille luotiin pk-IFRS –standardisto. Sen tarkoituksena on parantaa vertailukelpoisuutta eri maista tulevien yritysten välillä ja keventää raportoinnin raskautta. Tässä tutkielmassa selvitettiin, miten pk-IFRS:n soveltaminen vaikuttaa tilinpäätösten tekijöihin ja käyttäjiin. Tutkielma alkaa teoria-osuudesta, jossa käytiin läpi tuoreita tutkimuksia, minkä pohjalta esiin nousseita kysymyksiä käyttäen tehtiin empiria-osuudessa analysoitava haastattelu. Tutkimuksessa saatiin selville, että tutkijoiden ja haastateltavan näkemykset pk-IFRS:tä ovat pääosin samanlaiset. Pk-IFRS:n ongelmia on sen lyhyys, mikä aiheuttaa tulkintaongelmia ja monimutkaisuus, joka kuormittaa raportoijan resursseja. Pk-yritykset toimivat useimmin vain kotimaassa, jolloin hyödyt jäävät rajallisiksi. Pienemmissä pk-yrityksissä tilinpäätöksiä käyttäviä sidosryhmiä on vähän, jolloin käyttäjien saamat hyödyt ovat pienet. Kuitenkin käypään arvoon arvostus ja tiedon annon vaatimukset voivat helpottaa rahoituksen saantia joillekin yrityksille, jos pk-IFRS:ää aletaan soveltaa samalla tavalla joka maassa ja yrityksessä.

Tämän kandidaatintutkielman tavoite on tarkastella suomalaisten pk-yritysten maksuvalmiuden ja käyttöpääoman hallinnan välistä yhteyttä. Tarkoitus on selvittää, voidaanko suomalaisten pk-yritysten maksuvalmiutta parantaa käyttöpääoman hallintaa tehostamalla ja onko siitä saatava hyöty toimialariippuvaista. Toimialavertailuun valittiin rakentaminen, koneiden ja laitteiden valmistus sekä jälleenmyynti. Aineisto tutkimukseen hankittiin Amadeus-tietokannasta. Tutkimuksessa hyödynnetään tilastollisia menetelmiä. Tilastolliset analyysit suoritetaan SAS Enterprise Guide -ohjelmistolla. Muuttujien välisiä suhteita tarkastellaan regressioanalyysin avulla, jotka suoritetaan jokaiselle toimialaluokalle ja kaikista toimialoista koostuvalle otokselle erikseen. Tutkimustulosten mukaan toimialasta riippumatta pk-yrityksen maksuvalmiutta voidaan parantaa käyttöpääoman hallintaa tehostamalla. Vaikutuksen suuruus riippuu kuitenkin toimialasta. Tutkimustulokset huomioiden pk-yritysten johdon tulisi resurssien niukkuudesta huolimatta kiinnittää huomiota käyttöpääoman hallintaan, erityisesti silloin kuin yrityksen maksuvalmius on uhattuna.

Human and robots have complementary strengths in performing assembly operations. Humans are very good at perception tasks in unstructured environments. They are able to recognize and locate a part from a box of miscellaneous parts. They are also very good at complex manipulation in tight spaces. The sensory characteristics of the humans, motor abilities, knowledge and skills give the humans the ability to react to unexpected situations and resolve problems quickly. In contrast, robots are very good at pick and place operations and highly repeatable in placement tasks. Robots can perform tasks at high speeds and still maintain precision in their operations. Robots can also operate for long periods of times. Robots are also very good at applying high forces and torques. Typically, robots are used in mass production. Small batch and custom production operations predominantly use manual labor. The high labor cost is making it difficult for small and medium manufacturers to remain cost competitive in high wage markets. These manufactures are mainly involved in small batch and custom production. They need to find a way to reduce the labor cost in assembly operations. Purely robotic cells will not be able to provide them the necessary flexibility. Creating hybrid cells where humans and robots can collaborate in close physical proximities is a potential solution. The underlying idea behind such cells is to decompose assembly operations into tasks such that humans and robots can collaborate by performing sub-tasks that are suitable for them. Realizing hybrid cells that enable effective human and robot collaboration is challenging. This dissertation addresses the following three computational issues involved in developing and utilizing hybrid assembly cells: - We should be able to automatically generate plans to operate hybrid assembly cells to ensure efficient cell operation. This requires generating feasible assembly sequences and instructions for robots and human operators, respectively. Automated planning poses the following two challenges. First, generating operation plans for complex assemblies is challenging. The complexity can come due to the combinatorial explosion caused by the size of the assembly or the complex paths needed to perform the assembly. Second, generating feasible plans requires accounting for robot and human motion constraints. The first objective of the dissertation is to develop the underlying computational foundations for automatically generating plans for the operation of hybrid cells. It addresses both assembly complexity and motion constraints issues. - The collaboration between humans and robots in the assembly cell will only be practical if human safety can be ensured during the assembly tasks that require collaboration between humans and robots. The second objective of the dissertation is to evaluate different options for real-time monitoring of the state of human operator with respect to the robot and develop strategies for taking appropriate measures to ensure human safety when the planned move by the robot may compromise the safety of the human operator. In order to be competitive in the market, the developed solution will have to include considerations about cost without significantly compromising quality. - In the envisioned hybrid cell, we will be relying on human operators to bring the part into the cell. If the human operator makes an error in selecting the part or fails to place it correctly, the robot will be unable to correctly perform the task assigned to it. If the error goes undetected, it can lead to a defective product and inefficiencies in the cell operation. The reason for human error can be either confusion due to poor quality instructions or human operator not paying adequate attention to the instructions. In order to ensure smooth and error-free operation of the cell, we will need to monitor the state of the assembly operations in the cell. The third objective of the dissertation is to identify and track parts in the cell and automatically generate instructions for taking corrective actions if a human operator deviates from the selected plan. Potential corrective actions may involve re-planning if it is possible to continue assembly from the current state. Corrective actions may also involve issuing warning and generating instructions to undo the current task.

This work is a study in the Local Productive Arrangement of confections from Agreste of Pernambuco, as a relevant sector in economic and social aspect. This research has as central aim to understand how the inter-organizational relations influence the collective efficiency of arrangement. The theoretical framework employed highlights the approaches that deal with the benefits of business agglomeration for the develop­ment of firms and regions. It has discussed the approach of small and medium enter­ prises and industrial districts (SCHMITZ, 1997), which introduce the concept of col­ lective efficiency, explaining that only those externalities explained by Marshall (1996) are not sufficient to explain the competitive advantage of enterprises, expand­ing the idea that organizations achieve competitive advantage not acting alone. To examine the influences of relations in the collective efficiency, it has been taken as analytical perspective theory of social networks (GRANOVETTER, 1973, 1985; BURT, 1992; UZZI, 1997) because it has believe that this approach provides subsi­ dies for a structural analysis of social relationships in face the behavior of human ac­tion. By examining the organizations in a social network, you should understand the reason of this establishment of the relationship, their benefits, and as the information flow takes place and density of links between the actors (Powell; SMITH-DOERR, 1994). As for the methods, this study is characterized as a case study, in according to the purposed objectives, in addition to qualitative method. Also, due to recovering of the historical milestones of the arrangement, it is used a sectional approach with longitudinal perspective (VIEIRA, 2004). The primary and secondary data were used in order to understand the evolutionary process of the sector and their inter-actors re­ lationships in the arrangement for the promotion of development, for both, was used the contend and documentary analysis technique, respectively (DELLAGNELO ; SIL­VA, 2005). The approach of social networks has permitted understand that social re­lationships may extend the collective efficiency of the arrangement, and therefore need to develop policies that encourage the legalization of informal companies in ar­rangement, by showing up themselves representative. Thus, the relations estab­ lished in LPA of confections from Agreste of Pernambuco need for more effective mechanisms to broaden the collective efficiency. Therefore, this way as take place has directly benefited only a group of companies that are linked in some way the sup­portive institutions. So we can conclude that the inter-actor relations have limited the collective efficiency of LPA, being stimulated by the institutions in support only to groups of entrepreneurs, even those that produce external relations for all clustered companies

Ympäristöllinen kestävyys on ajankohtaisempi asia kuin koskaan ja sen merkitys yritysten yhtenä kestävyyden osa-alueena kasvaa jatkuvasti. Erityisesti suuret yritykset pyrkivät erottumaan kilpailijoistaan ympäristöllisen kestävyyden avulla, mutta myös pk-yritykset olisi tärkeää saada mukaan toiminnan kehittämiseen. Aikaisemmat tutkimukset yritysten ympäristöllisestä kestävyydestä ovat keskittyneet pääosin käytössä oleviin menetelmiin ja kestävyyden kehittämisen suurimpiin haasteisiin. Tärkeää olisi tutkia myös sitä, miten pk-yritykset saataisiin mukaan kehittämään toimintaansa ympäristöllisesti kestävämmäksi. Tähän pyritään löytämään vastauksia tässä diplomityössä. Diplomityön tarkoituksena on tutkia sitä, millä tavoin pk-yritykset haluavat kehittää toimintaansa ympäristöllisesti kestävämmäksi. Työn tavoitteena on suunnitella pk-yritysten tarpeita vastaava palvelukonsepti niiden ympäristöllisen kestävyyden kehittämiseksi. Tutkimuksessa hyödynnetään palvelumuotoilua ja sen prosessin kolmea ensimmäistä vaihet-ta: asiakasymmärryksen hankintaa, luovaa ideointia sekä palvelukonseptin kehittämistä. Tutkimus on laadullinen tutkimus, jonka tutkimusmetodina toimii palvelumuotoilun tärkein osa-alue eli yhteissuunnittelu. Yhteissuunnittelu toteutettiin visuaalisten työpajojen avulla suunnitteluun osallistuvien pk-yritysten kanssa. Tutkimuksen tuloksena saatiin suunniteltua pk-yritysten tarpeisiin räätälöity palvelukonsepti niiden ympäristöllisen kestävyyden kehittämiseksi. Palvelun tärkeimpiä ominaisuuksia ovat jatkuva tiedon lisääminen, kokonaisuuden hahmottamista helpottava visuaalisuus sekä palvelun virallisiin standardeihin pohjautuva kokonaisuus. Lisäksi palvelu mahdollistaa toiminnan kehittämisen pienin askelin sen porrastetun menetelmän ansiosta. Yksi tärkeä ominaisuus on myös palvelun tarjoama mahdollisuus tietojen helppoon ja nopeaan doku-mentointiin sekä jalostamiseen.

Background and aim: The aim of this study was to evaluate the efficacy of endoscopic band ligation (EBL) in carefully selected patients who would benefit from this method of resection. Methods: Patients with early upper gastrointestinal and small (< 15 mm) lesions treated with EBL (Duette® Multi-Band Mucosectomy) were prospectively recruited and retrospectively analyzed between 2010 and 2015. All cases were discussed in a multidisciplinary cancer committee and it was concluded that, owing to patient conditions, surgery was not possible and that not conducting histology would not change the clinical management. A first endoscopic control with biopsies was planned at 4-8 weeks. If there was no persistence of the lesion, new controls were programmed at 6 and 12 months. Results: The group (n = 12) included 5 esophagus lesions (adenosquamous carcinoma, n = 1; carcinoma squamous, n = 2; adenocarcinoma, n = 2); 4 gastric lesions (high grade dysplasia, n = 1; adenocarcinoma, n = 2; neuroendocrine tumor [NET], n = 1), and 3 duodenal lesions (NETs) (n = 3). The mean tumor diameter was 9.6 ± 2.8 mm (range 4-15). Only one minor adverse event was described. At first follow-up (4-8 weeks), there was 91.6% and 75% of endoscopic and histological remission, respectively. At 6-month follow-up there was 70% of both endoscopic remission and negative biopsies. And at 12 months, there was 100% and 75% of endoscopic and histological remission, respectively. Persisting lesions were T1 cancers. The median follow-up was 30.6 months. Conclusion: EBL without resection is an easy and safe technique that should be considered in patients with multiple morbidities and small superficial UGI lesions.
