Mentorici: Marija Urankar, Marija Jerše
Anketirali smo 28 kmetijskih gospodarstev na območju občin Železniki in Kamnik. Na tem
območju se kmetje ukvarjajo predvsem s pridelovanjem krme na travinju, v manjši meri pa s
poljedelstvom. Večina kmetij je velikih. Anketiranci so mnenja, da je dobro poskrbljeno za
zaščito čebel, predlagali so izobraževanja o medovitih rastlinah. Skoraj tretjina anketiranih
pogosto in zelo pogosto seje medovite rastline. Le malo anketirancev uporablja fitofarmacevtska
sredstva, od teh dve tretjini obveščata čebelarje o nameravanem tretiranju, ena tretjina pa ne.
Večina jih čebelam nevarna sredstva uporablja ponoči. 70 % anketirancev gnoji tako, da ne
zmanjšujejo deleža medovitih rastlin v ruši. Redno kolobari skoraj 43 % anketiranih, ostali pa
le občasno. V program KOPOP je vključenih 32 % anketirancev, 50 % anketirancev je tudi
čebelarjev. Anketiranci poznajo veliko pregovorov o čebelah.
We surveyed 28 agricultural holdings in the area of the municipalities of Železniki and Kamnik.
In the researched area, farmers are mainly engaged in forage production of grassland, and a
little bit less in agriculture. Most farms are large. Respondents have opinion that beekeepers in
our country take good care of bees and keep an eye on their protection. They suggested
education about melliferous plants. 71.43% of respondents frequently sow melliferous plants.
Few respondents use plant protection products, two thirds of them inform beekeepers about the
intended treatment, and one third do not. Most of them use herbicides that are dangerous to bees
at night. 70% of them fertilize in a way they do not reduce the proportion of melliferous plants
in turf. Almost 43% of the respondents rotate them regularly, while the rest only occasionally.
32% of respondents are included in the KOPOP program. 50% of respondents are also
beekeepers. Respondents are familiar with many proverbs about bees.

Mentorica: Marija Urankar
Na šolskem posestvu BC Naklo smo v triletnem sortnem poskusu (od leta 2018 do leta 2020)
rabarbare ugotavljali, katera sorta rabarbare je najprimernejša in daje največ pridelka. V poskusu
so bile štiri sorte: ‘Victoria’, ‘Champagne’, ‘Holsteiner Blut’ in ‘Livingstone’. Nasad rabarbare
smo vključili v ekološko pridelavo leta 2020. Poskus je pokazal, da je največji pridelek dala
sorta ‘Holsteiner Blut’, sorta ‘Livingstone’ je le malo zaostajala za njo. Sorta ‘Champagne’ je
dala trikrat manj pridelka od prej omenjenih sort. Na zadnjem mestu je sorta ‘Victoria’, ki pa ni
bila v enakovrednem položaju z ostalimi. V nasadu rabarbare so se v letu 2019 pojavile listne
uši, pegavost rabarbare in rjava pegavost rabarbare, rabarbarina plesen in gniloba koreninskega
vratu. V letu 2020 so se v večjem številu pojavili večletni pleveli. Sorta ‘Champagne’ je bila
najbolj občutljiva na gnilobo koreninskega vratu, ‘Holsteiner Blut’ pa na pegavost listov, čeprav
je ta bolezen zelo poškodovala vse sorte.
In a three-year experiment (from 2018 to 2020) on the BC Naklo estate we were determing
which variety of rhubarb is the most suitable and gives the highest yield. We experimented with
four species: ‘Victoria’, ‘Champagne’, ‘Holsteiner Blut’ and ‘Livingstone’. The plantation was
a part of organic production in 2020. The experiment has shown that the ‘Holsteiner Blut’
variety gives the highest yield, ‘Livingstone’ was very close behind it. The ‘Champagne’ variety
gave three times less yield than the other two varieties. The ‘Victoria’ variety gave the lowest
yield, but it wasn’t on the same starting place than the others. The plantation was attacked by
aphids, leaf spots, gray mold and rhubarb crown rot in 2019. In the year of 2020 many perennial
weeds started to grow. ‘Champagne’ was the most susceptible to the rhubarb crown rot,
‘Holsteiner Blut’ was the most susceptible for leaf spots, although that the illness harmed all the
species.

Letošnja tema festivala Več znanja za več turizma Moj kraj moj chef je bila priložnost za
razmislek o lokalnih specialitetah, ki bi se jih dalo narediti na drugačen ali povsem nov način.
Razvile smo recept za moderno jed oz. prigrizek, v kateri smo uporabile lokalne in tradicionalne
sestavine, ki smo jih poiskale pri lokalnih ponudnikih. Želele smo, da je jed enostavna in hitra
za pripravo, zato smo se odločile za mafine. Za izhodišče smo izbrale legendo o prihodu cesarja
Franca Jožefa v Naklo in njegovem poimenovanju kranjske klobase. Za dodatno popestritev
smo izbrale ajdovo moko. S predlaganim receptom za mafine želimo ljudem dati idejo za hiter
prigrizek, malico ali večerjo, poudariti pomen uporabe lokalnih sestavin in z modernejšim
pristopom obuditi kulturno dediščino. Verjamemo, da je naš izdelek zaradi vsega tega lahko
odličen turistični spominek občine Naklo, znajde se lahko na jedilnikih lokalnih gostinskih
ponudnikov in v naši šolski trgovini. Dodatna potrditev kvalitete recepta je osvojena nagrada v
ozaveščevalni kulinarični akciji izbiranja najboljših zimskih lokalnih receptov.
This year’s festival topic “More Knowledge for More Tourism: My Town – my Chef” presented
itself as an opportunity to reflect on local specialities, which could be prepared differently or in
a completely new way. A recipe for a modern dish or a snack, using local and traditional
ingredients, was our main objective. Therefore, we visited our local producers in order to find
suitable ingredients. As we wanted our dish to be easy and quick to make, we decided to make
muffins. We chose a legend about Emperor Franc Josef I who, while visiting Naklo, invented a
name for a local sausage. He named it a Carniolan sausage. In order to make our muffins more
appealing, we chose buckwheat flour. Our recipe will help people prepare a simple snack for
any meal of the day, as well as it emphasises the importance of locally produced ingredients and
cherishes the cultural heritage of one’s hometown. Consequently, we are certain that our product
can become an excellent souvenir of Naklo municipality, and it can be served in local inns and
restaurants. Since we have a school shop, we could also include it in our offer. Our recipe also
won the award for the best local recipe in wintertime, which we consider as an additional
appreciation of its quality.
Elektromagnetna sevanja
Šola: Biotehniški center Naklo

Mentor: Jure Ausec
Dandanes nas obkrožajo različne vrste naprav, ki so vir elektromagnetnih sevanj. Na spletu je
možno prebrati veliko člankov in zapisov o tem, kako nevarna in škodljiva so. Izvedli sva
meritve na različnih napravah in v njihovi okolici ter tudi meritve v okolici različnih objektov,
kot je npr. transformator, da ugotoviva, katere stvari sevajo več in katere manj, na katerem mestu
je sevanje največje in zakaj, ali res slabo vplivajo na zdravje človeka in posledično, kakšna je
varna razdalja od njih.
Ugotovili sva, da se največja elektromagnetna polja nahajajo na površinah naprav, ob pogoju,
da je naprava vklopljena, ko preko njenih sestavnih elementov teče električni tok.
Elektromagnetno polje se z oddaljenostjo zmanjšuje in je že nekaj cm stran od naprave zelo
majhno, zato npr. poslušanje radia, pri katerem je bilo sicer izmerjeno zelo veliko
elektromagnetno polje, ni nevarno, saj ga poslušamo na razdalji, večji od le nekaj cm. Poleg
radia je bilo veliko elektromagnetno polje izmerjeno pri računalniku in pametnem telefonu, pri
ostalih gospodinjskih aparatih pa so bila polja že na površinah naprav zelo majhna. Prav tako so
bile vrednosti nizke okrog transformatorja, razdelilne transformatorske postaje …, kar pomeni,
da ne predstavljajo nevarnosti glede EMS. Problem predstavlja pametni telefon, saj ga imamo
pogosto v žepu ali nekje ob sebi, torej na zelo majhni razdalji.
Nowadays we are surrounded by different gadgets which are the source of electromagnetic
radiation. We can read many different articles and notes about their dangers and side effects
the internet. As a part of the research we concluded an experiment in which we measured the
intensity of the electromagnetic field in different gadgets, in their surroundings as well as the
intensity of the electromagnetic field in the surroundings of different places such as
transformers. Our objective was to find out which of the gadgets create the strongest and which
ones the weakest radiation. We were also interested in the location of the radiation where it was
the strongest and tried to find the answer of why it was the strongest at a certain location. In
this research paper we wanted to prove the connection between radiation and different health
problems.
We found out that the strongest electromagnetic fields appear on the surfaces of the gadgets
when the gadgets are turned on and when the electricity currently flows through their circuit.
With the distance the electromagnetic field weakens.
For example, the electromagnetic field is quite strong when we listen to the radio, but it is not
dangerous because of the big distance from the listener. We got similar results at measuring the
electromagnetic field of computers and smart phones. When measuring the electromagnetic field
of household appliances, the measured radiation turned out to be low and insignificant. The
values were also low around the transformer, electrical substations, etc., which means that they
do not cause any dangers regarding to electromagnetic radiations. Smart phones, on the other
hand, are a great concern. They are especially dangerous when they are kept in our proximity.
Izbira partnerja glede na spol
Šola: Biotehniški center Naklo
Avtorica: Zala Lavttižar Žerjav
Mentorica: dr. Barbara Debeljak Rus
Ljudje smo socialna bitja in vsak posameznik ima potrebo po interakciji z ostalimi. V obdobju
mladostništva se pojavijo sekundarni spolni znaki, ki dečkom dajejo bolj moški videz, deklicam
pa bolj ženski. Pubertetniki se v tem obdobju začnejo zanimati za spolnost in raziskovati svoje
telo. Kmalu pride tudi čas, ko začnejo spletati partnerske vezi in preidejo v svet odraslosti.
Vsako osebo privlačijo določene lastnosti, tako vizualne, kot tudi karakterne. Moj cilj
raziskovalne naloge je bil ugotoviti, na kakšen način izbirajo partnerja dekleta in na kakšen
fantje. Rezultate sem navezovala s pridobljenim znanjem iz navedenih in opisanih knjig,
člankov, virov. Rezultate sem zbirala z anketnim vprašalnikom, ki je bil sestavljen objektivno
in vprašanja so bila razumljiva vsem anketirancem.
S pridobljenimi rezultati sem ovrgla oziroma obdržala postavljene hipoteze in ustvarila nek
zaključek. Dve hipotezi lahko pritrdim v celoti in sicer; »Ko ženska išče partnerja nameni večjo
pozornost njegovi osebnosti in zunanjosti.«, »Ko mlajši fant opazi privlačno žensko, pomisli
najprej na (seks) spolnost.«, eno hipotezo pa sem delno pritrdila; Moškega pri izbiri partnerice
privlačijo polne dojke in lepo oblikovana zadnjica.« Sklepam da imajo razlike v moških in
ženskih možganih vpliv na obnašanje. Na izbiro partnerja pa vplivajo tudi drugi dejavniki, kot
so npr. okolje v katerem živi posameznik in ljudje, ki ga obkrožajo. Raziskovanje takšne
tematike ponuja še veliko možnosti za raziskovanje. Moje priporočilo je, da bi v nadaljnje
raziskovali podoben raziskovalni problem s širšo populacijo ljudi različnih starosti. Zavedati se
moramo dejstva, da so razlike tudi med mladostniškimi in odraslimi možgani, kar lahko vpliva
na izbiro partnerja. Sklepam, da mladi izbirajo partnerja po drugačnih kriterijih kot zreli
možgani.
Humans are social beings and each individual has a need to interact with others. During
adolescence, secondary sexual characteristics appear, giving boys a more masculine
appearance and girls a more feminine one. Adolescents during this period begin to take an
interest in sexuality and explore their body. Soon there will come a time when they begin to forge
partnerships and move into the world of adulthood. Each person is attracted to certain qualities,
both visual and character. My goal of the research project was to find out in what way girls
choose partners and in what way boys. I related the results to the acquired knowledge from the
listed and described books, articles, sources. I collected the results with a questionnaire, which
was compiled objectively and the questions were understandable to all respondents.
With the obtained results, I refuted or kept the hypotheses and created a conclusion. I can affirm
two hypotheses in full, namely; “When a woman is looking for a partner, she pays more attention
to his personality and appearance.” “When a younger boy notices an attractive woman, he thinks
first of (sex) sexuality,” and I partially confirmed one hypothesis; When choosing a partner, a
man is attracted to full breasts and a nicely shaped buttocks. ”I conclude that the differences in
the male and female brains have an impact on behavior. The choice of partner is also influenced by other factors, such as. the environment in which the individual and the people around him
live. Researching such topics offers many more opportunities for research. My recommendation
is to further investigate a similar research problem with a wider population of people of different
ages. We need to be aware of the fact that there are also differences between the adolescent and
adult brains, which can affect partner choice. I conclude that young people choose a partner
according to different criteria than a mature people.
