a.three-dimensiona. model is used to investiga.e the mecha.ism of the South China.Sea.（SCS） winter counter-current （a.so known a. the SCS Wa.m Current, or the SCSWC）, which flows a.a.nst the wind. The model ca. reproduce the structure of the ba.d-like currents over the northern shelf of the SCS, including the westwa.d coa.ta. current a.d slop current, a.d the SCSWC sa.dwiched in between. Sensitivity experiments a.e designed to understa.d the different roles of Ekma. pumping of the SCSWC a. different longitude. The results show tha. the Ekma. pumping drives the SCSWC in the west segment. In the ea.t, it is not the Ekma. pumping but the intrusion of the Kuroshio tha. drives the SCSWC.

Brea.t ca.cer-specific gene 1 (BCSG1), a.so referred a. synuclein γ, wa. origina.ly iso-la.ed from a.huma. brea.t ca.cer cDNa.libra.y a.d the protein is ma.nly loca.ized to presyna.tic termina.s in the nervous system. BCSG1 is not expressed in norma. or benign brea.t lesions, but expressed a. a. extremely high level in the va.t ma.ority of the a.va.ced sta.ed brea.t ca.cinoma. a.d ova.ia. ca.cinoma.. Overexpression of BCSG1 in ca.cer cells led to significa.t increa.e in cell prolifera.ion, motility a.d inva.iveness, a.d meta.ta.is. To elucida.e the molecula. mecha.ism a.d regula.ion for a.norma. tra.scription of BCSG1, a.va.iety of BCSG1 promoter lucifera.e reporters were constructed including 3′ end deleted sequences, Sp1 deleted, a.d a.tiva.or protein-1 (a.1) doma.ns muta.ed. Tra.sient tra.sfection a.sa. wa. used to detect the tra.scriptiona. a.tiva.ion of BCSG1 promoters. Results showed tha. the Sp1 sequence in 5′-fla.king region wa. involved in the ba.a. tra.scriptiona. a.tivities of BCSG1 without cell-type specificity. In compa.ison to pGL3-1249, the reporter a.tivities of pGL3-1553 in BCSG1-nega.ive MCF-7 cells a.d pGL3-1759 in HepG2 cells were nota.ly decrea.ed. Muta.ions a. a.1 sites in BCSG1 intron 1 significa.tly reduced the promoter a.-tivity in a.l cell lines. Tra.scription fa.tors, c-jun, c-fos a.d cyclin a.P-responsive element binding (CREB) protein, could ma.kedly enha.ce the promoter a.tivities. Thus, our results suggest tha. the a.norma. expression of BCSG1 in brea.t ca.cer cells is likely regula.ed by multiple mecha.isms. The 5′ fla.king region of BCSG1 provides the ba.a. tra.scriptiona. a.tivity without cell type specificity. a.critica. promoter element involved in a.norma. expression of BCSG1 presents in the first exon. The cell type specificity of BCSG1 tra.scription is proba.ly a.fected through intronic cis-regula.ory se-quences. a.1 doma.ns in the first intron pla. a. importa.t role in control of BCSG1 tra.scription.

One of the outcomes of the thought provoking a.d stimula.ing conference for me wa. the rea.isa.ion tha. some of the problems experienced in the Chinese context a.e simila. to the ones Hunga.ia. foreign la.gua.e educa.ion fa.es. The first such issue is the efficiency of la.gua.e tea.hing in Hunga.y. a.cording to a.Europea. Union survey （Europea. Commission, 2012）, Hunga.y occupies the bottom pla.e with rega.d to the number of Hunga.ia.s who ca. spea. la.gua.es other tha. their mother tongue. This is despite the fa.t tha. the number of tea.hing hours during the first two yea.s of foreign la.gua.e tea.hing is a.ong the highest in Hunga.y within the EU （Europea. Commission/Ea.Ea. Eurydice, p. 105）, a.d tha. recommended minimum for a.nua. instruction time for foreign la.gua.es in compulsory educa.ion is more tha. the time spent tea.hing foreign la.gua.es in a.stria. which is 1 lth a.ong the 28 EU countries rega.ding the knowledge of foreign la.gua.es （Europea. Commission/Ea.Ea.Eurydice, pp. 106-7）. Secondly, it seems tha. in Hunga.y, too, there is a.ga. between the input a.d the output in tha. the input does not a.wa.s result in inta.e ma.eria.ising in the lea.ners＇ output. One perha.s wea. excuse for the dire sta.e of Hunga.ia. la.gua.e educa.ion ma. be tha. Hunga.ia., simila.ly to Chinese, is not a. Indo-Europea. la.gua.e, a.beit it is not a. different from English a. Chinese.
