ROLES OF EMPLOYEES IN THE PROCESS OF ACHIEVING ORGANIZATIONAL EXCELLENCE

Interes u vezi s ostvarivanjem organizacijske izvrsnosti zadržan je na razradi uloge zaposlenika u ostvarivanju organizacijske izvrsnosti. Prema mišljenjima većeg broja autora ostvarivanje organizacijske izvrsnosti rezultat je ostvarivanja principa efikasnosti i efektivnosti. Tako se omogućava uspješno ostvarivanje zadataka i poslovnih ciljeva poduzeća, zadovoljavanje potreba internih i eksternih čimbenika poslovanja. Razumljivo je da to neće automatski značiti i ostvarivanje uspješnosti, ali su dobar organizacijski okvir za funkcioniranje organizacije. Predmet istraživanja ovog rada je uloga zaposlenika u ostvarivanju organizacijske izvrsnosti; razrađuju se aspekti povezani s njihovom ulogom, daju se prijedlozi o postojanju timske organizacije kao dobrog načina organizacijskog dizajniranja poduzeća. Slijedeća dimenzija je povezana s ulogom tzv. feedbacka i njegovog značaja za postizanje organizacijske izvrsnosti, pri čemu su u radu dani primjeri nepostojanja feedbacka u realnim situacijama i posljedica takvoga stanja. Sagledano je i zadovoljstvo zaposlenika kao jedan od čimbenika od utjecaja na organizacijsku izvrsnost, a što je od izuzetnog značaja u današnjim uvjetima organiziranja radnika i njihovih uvećanih potreba.Every sound organization strives for Business Excellence and thereby company, customer and employee satisfaction. Several Business Excellence Models are applied in organizations throughout the world. But what do the models accomplish? What can, the leading organization in every area, benefit from using these models? An organization is a very complex object to measure. Organizations are different in many aspects, for example, size, complexity and types of customer. Some people argue that what you really want to know about an organization is impossible to measure. I believe, or rather hope, that is not true. The fact that most organizations do measure their performance, and, in my view, should continue to do so, means that there must be substance in organizational performance measurements. This paper aims to reveal whether today’s roles of employees are used to their full potential or if there is room for improvement

E-UČENJE U RUKAMA GENERACIJE Y I Z

There have been a number of papers revolving around e-learning, since technological advancement has triggered interest and development for all online platforms. Still, the application of e-learning is not merely a technological solution, but a process involving many diverse factors such as social and behavioral contexts. The paper primarily focuses on the basic features of the most relevant generations currently representing the core workforce, Generation Y and the upcoming Generation Z. This will form the basis for assumptions which will be tested with regard to the troubling labor market, at the same time connecting these generations with considerations about e-learning. Based on deductive reasoning, the focus is on the types of training, with a discussion of the main aspects and content of this type of learning. Despite the theoretical discussion, appropriate practical empirical research including the members of the mentioned generations and their applications of e-learning has been incorporated. Additionally, several relevant conclusions are made taking into account different variables related to e-learning based on a sample consisting of members of Generation Y and Generation Z. Th e research will present certain indications related to generations Y and Z, their orientation and willingness to use e-learning, primarily resulting from the characteristics and availability of the appropriate information technology. Although the research is rather new it should be noted that Generation Z was born and raised with the web, they are digital-centric and technology is their blood. This paper should be given its practical and applied dimension by conducting relevant research. Th is analysis will off er insights into significant issues concerning e-learning and provide the foundations for further discussion on the trends related to the generation currently present as the dominant workforce and their attitude towards e-learning. The limitations of the research are embedded in the struggle to measure some of the differences and characteristics within the different generational groups.Otkada je tehnološki napredak potaknuo zanimanje za sve online platforme kao i njihov razvoj pojavio se veći broj radova usredotočenih na e-učenje. Ipak, primjena e-učenja ne predstavlja samo tehnološko rješenje, već je riječ o procesu koji obuhvaća brojne i raznovrsne čimbenike kao što su društveni čimbenici i oni povezani s ponašanjem. Ovaj se rad prvenstveno bavi temeljnim odlikama najrelevantnijih generacija koje trenutno predstavljaju radnu snagu – generacijom Y i nadolazećom generacijom Z. To je temelj za pretpostavke koje će se ispitati s obzirom na problematično tržište rada, istovremeno povezujući te generacije s razmatranjima o e-učenju. Uz pomoć deduktivnog rasuđivanja, u središtu zanimanja su vrste obučavanja uz raspravu o glavnim aspektima i sadržaju ove vrste učenja. Pored toga, iznijet će se nekoliko relevantnih zaključaka s obzirom na različite varijable povezane s e-učenjem na temelju uzorka koji se sastoji od pripadnika generacija Y i Z. Istraživanje će iznijeti određene pokazatelje povezane s generacijama Y i Z, njihovom orijentacijom i spremnošću da koriste e-učenje, a koji su prvenstveno rezultat odlika i dostupnosti prikladne informacijske tehnologije. Iako je istraživanje prilično novo, treba napomenuti da je generacija Z rođena i odrasla uz internet, da su usmjereni na digitalno, a tehnologija im je u krvi. Ovaj bi rad trebao dobiti praktičnu i primijenjenu dimenziju provođenjem relevantnih istraživanja. Ova će analiza ponuditi uvid u važna pitanja u pogledu e-učenja te pružiti temelj za daljnje rasprave o trendovima povezanima s generacijom koja trenutno čini dominantni dio radne snage te o stavovima pripadnika te generacije u pogledu e-učenja. Ograničenja istraživanja izviru iz poteškoća u mjerenju određenih razlika i odlika različitih generacijskih skupina

The role of bonding and bridging cognitive social capital in shaping entrepreneurial intention in transition economies

Entrepreneurship is an important factor of potential growth and development that will determine the development dynamics of transition countries in the future. Starting from the theory of planned behaviour and the social cognition theory, the paper argues that bonding and bridging cognitive social capital may positively influence entrepreneurial intentions of young people in Croatia and Macedonia. The hypotheses were tested by using structural equation modelling. Our findings indicate that bridging and bonding social capital could be significant enhancers of entrepreneurial intention. The fact that those individuals who have poor bonding social capital may get their chance through bridging social capital seems as a good indicator. Bridging social capital that forms in an entrepreneurial environment can encourage young people in their self-employment efforts. Furthermore, our research implies several possible

Orientation of Airborne Laser Scanning Point Clouds with Multi-View, Multi-Scale Image Blocks

Comprehensive 3D modeling of our environment requires integration of terrestrial and airborne data, which is collected, preferably, using laser scanning and photogrammetric methods. However, integration of these multi-source data requires accurate relative orientations. In this article, two methods for solving relative orientation problems are presented. The first method includes registration by minimizing the distances between of an airborne laser point cloud and a 3D model. The 3D model was derived from photogrammetric measurements and terrestrial laser scanning points. The first method was used as a reference and for validation. Having completed registration in the object space, the relative orientation between images and laser point cloud is known. The second method utilizes an interactive orientation method between a multi-scale image block and a laser point cloud. The multi-scale image block includes both aerial and terrestrial images. Experiments with the multi-scale image block revealed that the accuracy of a relative orientation increased when more images were included in the block. The orientations of the first and second methods were compared. The comparison showed that correct rotations were the most difficult to detect accurately by using the interactive method. Because the interactive method forces laser scanning data to fit with the images, inaccurate rotations cause corresponding shifts to image positions. However, in a test case, in which the orientation differences included only shifts, the interactive method could solve the relative orientation of an aerial image and airborne laser scanning data repeatedly within a couple of centimeters

Хирургическое лечение злокачественной опухоли желудка у пациента с хронической болезнью почек на программном гемодиализе

Background. Gastric cancer is the world 5th top malignancy, with treatment success largely conditioned by comorbidity. Patients with end-stage renal failure developed with chronic kidney disease could not expect a specialty cancer treatment before the advent of long-term haemodialysis.Aim. A case description of successful perioperative therapy and surgery in a long-term haemodialysis patient performed by a multi-specialty team of oncologists and transplantologists.Materials and methods. We case-illustrate surgical treatment options in a gastric cancer patient with long-term haemodialysis.Results and discussion. A specialty oncological treatment of end-stage renal failure patients requiring long-term haemodialysis is a complex multidisciplinary task feasible in hospitals equipped for different haemodialysis regimens. The treatment plan should be laid out by a multi-specialty team, as chronic kidney disease influences the choice of the drug class, dosage and administration mode. Moreover, such patients need laboratory (control of acid-base balance, haemoglobin, electrolytes, creatinine and urea) and clinical (body weight, liquid balance, etc.) monitoring.Conclusion. Perioperative management studies in gastric cancer and chronic kidney disease-comorbid patients under long-term haemodialysis is a promising area of combining eff ort in oncology and transplantation science. Further research is needed in this topic for data enrichment and analysis in complex comorbidity patients.Введение. Рак желудка является 5-й по частоте встречаемости злокачественной опухолью в мире. Результаты лечения данной неоплазии в значительной степени определяются коморбидностью. Пациенты с терминальной почечной недостаточностью на фоне хронической болезни почек до внедрения в клиническую практику программного гемодиализа не могли рассчитывать на проведение специализированного лечения онкологического заболевания.Цель работы: презентация клинического случая успешной работы мультидисциплинарной команды онкологов и трансплантологов по периоперационной терапии и хирургическому вмешательству у пациента на программном гемодиализе.Материалы и методы. В публикации представлен клинический случай, иллюстрирующий возможности хирургического лечения пациента со злокачественным новообразованием желудка на программном гемодиализе.Результаты и  обсуждение. Специализированное онкологическое лечение пациентов с  терминальной стадией почечной недостаточности, нуждающихся в проведении программного гемодиализа, является сложной мультидисциплинарной задачей. Оно возможно в условиях стационаров, обладающих возможностью проведения программного гемодиализа в различных режимах. План лечения таких пациентов должен составляться мультидисциплинарной командой специалистов, поскольку наличие хронической болезни почек влияет на выбор класса препаратов, их доз и режима введения. Кроме того, эти пациенты нуждаются в лабораторном (контроль кислотно-щелочного баланса, гемоглобина, уровней электролитов, креатинина и мочевины) и клиническом мониторинге (динамика массы тела, баланс жидкости и т. д.).Заключение. Изучение особенностей периоперационного ведения пациентов со злокачественными опухолями желудка и хронической болезнью почек на программном гемодиализе является перспективным направлением совместной работы онкологов и трансплантологов. Необходимо проведение дальнейших исследований в этом направлении с накоплением и анализом базы данных пациентов с подобными сложными факторами коморбидности

Рак желудка у пациентов моложе и старше 50 лет: характеристики опухолевого процесса, анализ выживаемости

Objective. To study clinical and pathological characteristics of gastric cancer in patients aged younger and older than 50 years, who received anticancer treatment including surgery, as well as to identify prognostic factors for overall survival of these patients.Material and methods. A retrospective study of surgical treatment outcomes was conducted in 350 gastric cancer patients, who were divided into 2 groups. The study group included 34 (9.71 %) patients aged 50 years and younger and the control group consisted of 316 (90.29 %) patients aged 51 years and older.Results. The analysis of treatment outcomes and survival rates was carried out. The diffuse-type gastric cancer was more frequently diagnosed in younger than in older patients (p<0.001), and asymptomatic disease often present in younger patients (p<0.001). There were no differences in the extent of surgery between the groups (p=0.613). The overall survival rate was lower in the control group than in the study group (p=0.002). The multivariate analysis revealed that a worse prognosis was observed in patients of the control group (hr=12.71), with regional lymph node metastases (hr=2.64), distant metastases (hr=1.83), iii/iv stage of the disease (hr=2.01), lymphovascular (hr=3.15) and perineural invasion (hr=2.46), as well as with postoperative complications (hr=2.12). Adjuvant chemotherapy improved the disease prognosis (hr=0.35).Conclusion. Specific clinical and pathological features predicted survival of gastric cancer patients aged younger and older 50 years.Цель исследования – изучить особенности рака желудка у больных моложе и старше 50 лет, получивших противоопухолевое лечение с хирургическим компонентом, и установить предикторы прогноза общей выживаемости для каждой из групп.Материал и методы. Проведено ретроспективное исследование непосредственных и отдаленных результатов хирургического лечения пациентов с раком желудка в ООХМЛ 5 ГБУЗ «ВОКОД» за три года. Выборка разделена на две группы: основную (50 лет и моложе) и контрольную (51 год и старше).Результаты. Из 350 пациентов, вошедших в анализ, 34 (9,71 %) были отнесены к основной группе и 316 (90,29 %) к контрольной. Заболевание у более молодых пациентов чаще протекало бессимптомно (p<0,001), они чаще имели опухоли с диффузным типом роста (p=0,001). Различий в объеме хирургического лечения между группами не отмечено (p=0,613). Общая выживаемость была ниже в контрольной группе (p=0,002). Многофакторный анализ позволил установить, что прогноз для всей совокупности пациентов ухудшается при принадлежности пациентов к контрольной группе (HR=12,71), метастазах в регионарные лимфатические узлы (HR=2,64), отдаленных метастазах (HR=1,83), iii/iV стадии заболевания (HR=2,01), лимфоваскулярной (HR=3,15) и периневральной инвазии (HR=2,46), а также осложнениях после хирургического лечения (HR=2,12). Фактором, улучшающим прогноз, явилось проведение адъювантной химиотерапии (HR=0,35).Выводы. Пациенты с раком желудка моложе и старше 50 лет имеют ряд клинико-патологических особенностей, обусловливающих прогноз выживаемости
