...when I visited Krakow for 4 months in 2007, I liked watching this soap opera. Though I didn't really understand much, since my Polish language skills are limited. Who sings that beautiful theme song of 'Na Dobre i Na Zle' and what do the words mean?

I've been in Krakow almost two months ago and realized that there were a lot of antisemitic graffiti on walls. In fact I just looked at the pictures I've taken and found two on them. Who can tell me what "JPG" sprayed on synagoge walls together with a crossed out Star of David stands for? I'd like to know what this exactly means as it looks like an abbrevitation for something.
And what does "Jebac policie Zydzew" mean? Moreover there was LKS. What do these things mean? As I do not speak Polish I'd need some help of Polish people who are familiar with these graffitis as they are to be seen all over Poland.
I can't imagine that "LKS" in this case has to do with soccer because if so, what does the Star or David do inside? See for example here =>

And they write the "K" inside the star. (Which is not in this picture but in mine it is)

I went to Krakow on Easter. Had amazing time there. Lovely city. I climbed to the Krakow mound. There was a festival kind of thing. Sellers were selling old polish folk costume, accessories etc. I bought a woman hair accessory. It is like a wreith and you wear it on your head.

Here is the question. I do need to learn which region in Poland it'd be used in old times? Is it like daily costume or would it be put on only festival times(dancing) or special days?
I'm college student and study social science. I havent found anything about this wreath (went to library, called conculs, seached on internet but nothing)

I can send the photo of this accessory and mail, if someone want to help me

When I visited Krakow in 2007, I struggled to learn the Polish language. I would tell people there Polish is a hard language to learn, they would say it is supposed to be one of the most difficult languages to learn...comparing it to the Chinese language in difficulty. Is that true?

The Jagellonski University in Krakow offers a fantastic summer program for students, but it's for college students. I'm in high school and I am very much interested in a language learning program for the Polish language, most preferably in Krakow.

Does anyone know of any camps or summer programs in Poland like this? Please only answer if you know.
