Meetings: First Friday of the month in Room 5 at 7:00 a.m. Advisor: Ms Mary Beth Nawor, _ Peer Tutoring Students volunteer to help fellow students in improving their academic and organizational skills. Students tutor LFHS and middle school students on an individually scheduled basis. LFHS tutors must have proficiency in the academic area in which they wish to tutor, but middle school tutors only need general academic proficiency. Meetings: All tutoring is done on an individually scheduled basis. Advisor: Ms Kathy O'Hara, _ Young Idea Young Idea is LFHS's art and literary magazine. Students of all ages who love writing and art are encouraged to become part of the staff of this award-winning magazine. Young Idea encourages all students to submit art and literature works to the magazine, whether they are a part of the staff or not. From September to February, Young Idea meets on Thursdays after school in the Public Room to discuss the pieces that have been submitted to the magazine and provide feedback for the authors. Meetings: See above explanation. Advisor: Ms Debbie Zare, _ Scout Buddies Scout Buddies is a friendship club which helps build friendship among individuals with and without disabilities. Club members participate in a variety of social activities both within the school and in the community. Activities include organizing holiday parties in the school, bowling, going to the movies, and eating out in local restaurants. Meetings: Monthly meeting dates vary, but in Room 134.

Question: Which club provides help for students poor in study?
peer tutoring.

Context: Ten-year-old Chihiro (voice: Daveigh Chase in the 2002 English dub) and her parents (voices: Lauren Holly and Michael Chiklis) drive to their new home. Chihiro is whiny and unhappy about the move, especially when she notices that the bouquet her friend gave her as a good-bye gift is wilting. In sight of their new house, they take a wrong turn and follow a bumpy, decayed old road through the woods; Chihiro sees an odd old statue through the trees as they drive by. The road ends at a tunnel leading to an abandoned theme park. It gives Chihiro the creeps, but her parents persuade her to go in with them and look around.After wandering across a grassy landscape and a dry riverbed, they climb a stone staircase and come to a street lined with restaurants and shops. Most are deserted, but the aroma of cooking leads them to the one restaurant that's well stocked with food -- though it's mysteriously deserted. Mom and Dad are hungry and start eating, despite Chihiro's objections. The food is delicious, and Chihiro wanders away to explore while they eat. She finds a towering, ornate building that she recognizes as a bathhouse (a spa resort); there's a train track running under it. She meets a boy (voice: Jason Marsden) in traditional dress who is alarmed to see her; he tells her to leave and get back across the river before it gets dark. Chihiro runs back to her parents, but they're still eating -- and they've turned into pigs. Strange, dark, ghostly figures appear in all the shops and streets, frightening Chihiro and separating her from the pigs that were her parents. Chihiro runs back to the river, which was nearly dry when they came over but is now full and large, and she doesn't even recognize the buildings on the far side. As a riverboat approaches, she notices that her body has become transparent.The riverboat lands a big crowd of people in costume -- or maybe they're not people; at first they're only visible as paper masks. Chihiro thinks shes dreaming, but can't wake up. The boy who warned her away finds her and tells her she must eat some food from his world or she'll fade away. He assures her that she won't turn into a pig. She swallows the morsel he gives her and becomes solid, but finds that she's stuck to the ground until he recites an incantation to release her. A bird with a woman's head flies above them and he hides her, saying the bird is looking for her. They run through alleys and the pig barn to the big bathhouse, which is accessed by a bridge; the boy says she has to hold her breath as they cross the bridge or the spell that makes her invisible will be broken. Customers -- fantastically varied gods and spirits -- are crossing the bridge and being greeted by bathhouse staff. Chihiro makes it almost all the way across, but a frog (voice: Bob Bergen) that speaks to her companion (calling him Haku) startles her and she takes a breath. Luckily only the frog seems to see her, and Haku uses magic to encase it in a bubble to shut it up.Haku tells her to find Kamajii (voice: David Ogden Stiers), the boiler man, and make him give her a job; she must have a job to stay at the bathhouse, or else Yubaba (voice: Suzanne Pleshette), the old witch who rules the bathhouse, will turn her into an animal. And Haku says she has to stay if she wants to find and help her parents, who are still pigs, wherever they are. He knows her name and says he's known her since she was very small.Chihiro descends a steep, winding, rail-less wooden stairway in search of Kamajii and the boiler room. When she finds them, she sees a weird set-up in which the boiler is fed by creatures like spiders (delivering coal one lump at a time) and the machinery is controlled by a bearded, bald man
Question: Who used the black slug to control Haku?
yubaba

Context: The Ehlers-Danlos syndrome is characterized by abnormal connective tissue but bone involvement is debated. We found a reduced BMD and bone quality and increased prevalence of asymptomatic vertebral fractures in eugonadal patients with Ehlers-Danlos syndrome. These findings suggest the need of a bone health evaluation in these patients. The Ehlers-Danlos (EDS) syndrome is characterized by abnormalities of the connective tissue leading to ligamentous laxity and skin and tissue fragility. We evaluated the bone metabolism, bone mineral density (BMD) and bone quality (measured by trabecular bone score, TBS), and the prevalence of vertebral fractures (VFx) in a group of eugonadal adult EDS patients. Fifty consecutive Caucasian patients, aged 30-50years (36 females, 14 males) with classical or hypermobility EDS and 50 age-, gender-, and body mass index (BMI)-matched control subjects were enrolled. In all subjects' calcium-phosphorous metabolism, bone turnover, BMD at the lumbar spine (LS) and femur (femoral neck, FN and total femur, FT) and TBS by dual-energy X-ray absorptiometry, and the VFx presence by spine radiograph were assessed. Patients showed reduced BMD (Z-scores LS -0.451.00, FN -0.561.01, FT -0.580.92) and TBS (1.2990.111) and increased prevalence of morphometric VFx (32%) than controls (Z-scores LS 0.091.22, FN 0.010.97, FT 0.080.89; TBS 1.3820.176; VFx 8%, p <0.05 for all comparisons), while vitamin D levels, calcium-phosphorous metabolism, and bone turnover were comparable. Fractured EDS patients showed lower TBS values than non-fractured ones (1.2450.138 vs 1.3250.086, p<0.05), despite comparable BMD. In EDS patients, the VFx presence was significantly associated with TBS even after adjusting for sex, age, BMD, EDS type, and falls frequency. EDS patients have reduced BMD and bone quality (as measured by TBS) and increased prevalence of VFx.
Question: What tissue is most affected in Ehlers-Danlos syndromes?
