Succeeding in small board lot (0-20 tons) deliveries, is not always prosperous and failures as well as extra costs compared to standard costs arise. Failure deliveries from converting plants to customer locations tie a lot of unwanted and unexpected costs. Extra costs are handled as quality costs and more precise, internal failure costs. These costs revolve from unsuccessful truck payloads, redundant warehousing or unfavorable routing as examples. Quality costs are becoming more and more important factor in company’s financial decision making. Actual, realized truck payload correlates with the extra costs occurring, so filling the truck payload all get-out well is a key to lower the extra costs. Case company in this study is Corporation A, business segment Boards. Boards have outsourced half of their converting in order to gain better customer service via flexibility, lead time reductions and logistics efficiency improvements. Examination period of the study is first two quarters of year 2008 and deliveries examined are from converters to the customer locations. In Corporation A’s case, the total loss in failure deliveries is hundreds of thousands of Euros during the examination period. So, the logistics goal of getting the right product to the right place and right time for the least cost, does not completely realize.

Cardiac troponins (cTns) are the recommended biochemical markers in the diagnosis of myocardial infarction (MI). They are very sensitive and tissue-specific but are limited by their delayed appearance in the circulation. Biochemical markers with more rapid release kinetics, e.g. myoglobin and especially heart-type fatty acid-binding protein (H-FABP), have been used to enhance the early identification of MI. The implementation of cTns into clinical practice has shown that cardiomyocyte injury occurs in many other clinical conditions than MI. The aim of this study was to evaluate the impact of modern and highly sensitive cTnI assays on the early diagnosis of MI. In a patient cohort with suspected MI, such a sensitive cTnI assay enhanced the early diagnostic accuracy when compared to a less sensitive cTnI assay and to myoglobin. When compared to H-FABP during the early hours after symptom onset, the sensitive cTnI assay showed at least similar and, after 6 hours, superior diagnostic accuracy. A positive cTnI test result had superior prognostic value when compared to H-FABP, even among early presenters. The prognostic value of cTn in acute heart failure (AHF) was evaluated in 364 patients who participated in the FINN-AKVA study. The patients presented with AHF but no acute coronary syndrome (ACS). Up to half of the patients had elevated cTn levels which were associated with higher 6-month mortality. The magnitude of cTn elevation was directly proportional to mortality. Finally, the clinical spectrum of cTnI elevations was evaluated in 991 cTnI positive emergency department (ED) patients. 83% of the patients had MI and 17% had cTnI elevation due to other clinical conditions. The latter patient group was characterized by lower absolute cTnI levels and – importantly – higher in-hospital mortality when compared to the MI patients. In conclusion, the use of a highly sensitive cTnI assay enhances the early diagnostic accuracy and risk stratification in suspected MI patients. Cardiac troponin elevations are highly prevalent also in other acute clinical conditions and indicate an adverse outcome of these patients.

Metsäteollisuuden kiristyvä kilpailutilanne ja globalisoituminen ajavat metsäteollisuusyritykset uuteen tilanteeseen. Säästöä ja tehokkuutta pyritään hakemaan kaikin keinoin ja kaikesta toiminnasta. Samalla kehitetään uusia liiketoimintamuotoja tukemaan jo olemassa olevia ja korvaamaan vanhentuneita. Uuden tuotteen lanseeraus ei aina käy kivuttomasti, eikä elinkaarensa alkuvaiheessa tuotteen valmistaminen välttämättä tuota toivottua taloudellista tulosta. Verrattain uuden vanerituotteen kustannustehokkuuden parantamisen tarve havaittiin myös kohdeyrityksessä. Kirjallisuuden perusteella selvitettiin kohdeyrityksen tilanteeseen soveltuvia menetelmiä tietyn vanerituotteen valmistuskustannusten alentamiseksi. Tavoitekustannuslaskenta, Kaizen-laskenta ja jatkuvan parantamisen periaatteet ovat yleisesti tunnettuja menetelmiä tuotteen valmistuskustannusten hallitsemiseen. Näitä menetelmiä sovellettiin työssä kohdeyrityksen tarpeen mukaisiksi, tavoitteena tietyn vanerituotteen valmistuskustannusten alentaminen. Aluksi paikallistettiin tuotteen kustannusten muodostuminen ja suurimmat kustannuksia aiheuttavat tekijät. Selvityksen pohjalta määritettiin konkreettisia kustannustehokkuutta parantavia toimenpiteitä. Raaka-aineen kulutuksen vähentäminen ja tuoterakenteiden optimointi havaittiin teoreettisten laskelmien perusteella tehokkaimmiksi valmistuskustannusten alentamiskeinoiksi.
