Prirodni procesi idealni su primjer za provođenje nastave usmjerene prema djelovanju koja daje učenicima mogućnost preuzimanja inicijative u učenju gdje radoznalost, kreativnost i eksperimentiranje s ...idejama nadmašuju zacrtani plan tradicionalne nastavne teme. Ako se u cijeli proces uključe interdisciplinarnost i informacijsko – komunikacijske tehnologije, teorijski koncepti postaju realistični, učenicima olakšavaju razumijevanje realnih događanja kojima svjedoče svaki dan. U našoj svakodnevici promatramo i doživljavamo stanja flore i faune kroz osjetila za miris, sluh, vid itd. Međutim, postoji mogućnost dokazivanja da se mogu doživjeti i druge informacije u našoj okolini. Paralelnim snimanjem i bilježenjem u vidljivom i infracrvenom spektru dobivamo dvostruke informacije naše okoline. Kako izgledaju objekti i priroda u bliskom infracrvenom spektru? Informacije koje nose objekti, biljke i živa bića u bliskom infracrvenom spektru moguće je usporediti sa doživljajem u spektru kojega percipira naše oko. Postoji korelacija refleksije svjetla između vizualne i infracrvene apsorpcije. Razlika vizualne i infracrvene apsorpcije svjetla na flori i fauni omogućuje kamuflaže u kretanju i u okolišu. Skrivanje u flori i fauni posebno je zanimljivo. U radu pokazujemo sinkroniziranu interdisciplinarnost i primjenu tehnologije u odgojno – obrazovnom procesu u kojemu se uspostavlja odnos sa „stvarnim životom“, životnim okruženjem učenika, uzajamnom povezanosti stvari u životu sa svim ostalim aspektima određene znanosti, discipline ili predmeta, a rezultat je aktivnosti koje u sinergiji provode učenici prirodoslovno-matematičkog usmjerenja i nastavnici.

Natural processes are an ideal example of actionoriented teaching that gives students the opportunity to take the initiative in learning where curiosity, creativity, and experimentation with ideas go ...beyond the set scenario of a traditional teaching topic. If interdisciplinarity and information and communication technologies are included in the process, theoretical concepts become realistic, making it easier for students to understand the real events they witness every day. In our everyday life, we observe and experience the state of flora and fauna through the senses of smell, hearing, sight, etc. However, there is the possibility of proving that other information can be experienced in our environment. By parallel recording in the visible and infrared spectrum, we obtain double information about our environment. What do objects and nature look like in the nearinfrared spectrum? The information carried by objects, plants, and living beings in the near-infrared spectrum can be compared to the experience in the spectrum perceived by our eye. There is a correlation of light reflection between visual and infrared absorption. The difference between visual and infrared light absorption on flora and fauna allows camouflage in motion and in the environment. Hiding in flora and fauna is especially interesting. The paper shows the synchronized interdisciplinarity and application of technology in the educational process in which a relationship is established with "real life", the living environment of students, and the interconnectedness of things in life with all other aspects of science, discipline or subject. The result is activities that are carried out in synergy by students of science and mathematics and teachers.
Background and Purpose: Childhood overweight/obesity is considered
a global epidemic, which began earlier in pediatric patients and presents a major health risk in adulthood. It is well known that ...adipose tissue is an active endocrine inflammatory organ in obese adults, but its neurohormone activity in the childhood is not yet clarified. Visfatin is one of adipokines with insulin-mimetic and proinflammatory-atherosclerotic effect, whose role in the child’s age is still unknown as well as its physiological concentrations in serum of prepubertal children. The aim of this study was to determine visfatin serum concentration at the early age in eutrophic and overweight/obese male children and its association with arterial blood pressure.
Materials and Methods: Healthy boys, 2-14 years old, hospitalized for
elective inguinal hernia surgery has been included in the study (N=31) and were divided into two groups according to percentile curve: a) overweight/obese (O/O:above the 85th percentile) and b) eutrophic (E:5th-85th percentile). Anthropometric and biochemical measurements and specific serum levels of visfatin by enzyme immunoassay were determined.
Results and Conclusion: Both groups of examinees, eutrophic and overweight/obese, had a normal metabolic profile band on percentile ranks (fasting glucose values and all fractions of lipid profile) and values of blood pressure. However overweight/obese boys had significant higher systolic blood pressure than eutrophic boys, p=0,028. Serum visfatin were 6.90±3.97 ng/ml in eutrophic boys, while in overweight/obese were 7.82±3.75 ng/ml, p=0,57. There is a tendency of visfatin serum concentration to increase with increase of body weight and growing. This suggests possible role of visfatin in future
metabolic and cardiovascular processes related to increase in body mass.
