Comment faciliter l'apprentissage du français pour rendre notre enseignement plus efficace? Beaucoup de recherches ont ${\acute{e}}t{\acute{e}}$ $men{\acute{e}}es$ sur cette question; en $r{\grave{e}}gle$ $g{\acute{e}}n{\acute{e}}rale$ l'enseignement de la langue d'une part et l'expression ${\acute{e}}crite$ et la $r{\acute{e}}flexion$ d'autre part ${\acute{e}}taient$ $men{\acute{e}}es$ $ind{\acute{e}}pendamment$. Notre intention dans ce $pr{\acute{e}}sent$ travail a ${\acute{e}}t{\acute{e}}$ d'introduire et $d^{\prime}e xp{\acute{e}}rimenter$ pendant $l^{\prime}ann{\acute{e}}e$ scolaire des cours associant le $d{\acute{e}}bat$ $d^{\prime}id{\acute{e}}e$ et la $r{\acute{e}}flexion$ $th{\acute{e}}matique$ avec l'apprentissage linguistique(grammaire, vocabulaire${\dots}$), afin de susciter $l^{\prime}i nt{\acute{e}}r{\hat{e}}t$ des apprenants, leur $curiosit{\acute{e}}$ et leur $vivacit{\acute{e}}$, au $del{\grave{a}}$ des $d{\acute{e}}fis$ $pos{\acute{e}}s$ par la langue française. Nous avons en particulier $utilis{\acute{e}}$ une $publicit{\acute{e}}$ comme support d'apprentissage des bases linguistiques et comme moteur $d^{\prime}{\acute{e}}veil$ ${\grave{a}}$ la civilisation française pour mobiliser leur attention et stimuler leur $activit{\acute{e}}$ cognitive par $l^{\prime}interdisciplinarit{\acute{e}}$. Nous avons donc $expos{\acute{e}}$ ici les exemples d'argumentation autour les deux $s{\acute{e}}quences$ publicitaires conduites avec les ${\acute{e}}tudiants$ et les arborescences $d{\acute{e}}gag{\acute{e}}es$ de ces analyses. Presque concomittamment ${\grave{a}}$ "voir" et "${\acute{e}}couter$", l'information est $trait{\acute{e}}e$ par $l^{\prime}activit{\acute{e}}$ "$d{\acute{e}}coder$". Nous approfondissons ensemble cette $interpr{\acute{e}}tation$ $s{\acute{e}}miotique$, et l'analyse de la façon dont la $publicit{\acute{e}}$ capte l'attention du spectateur nous $am{\grave{e}}ne$ ${\grave{a}}$ $d{\acute{e}}gager$ des faits de $soci{\acute{e}}t{\acute{e}}$ et ${\grave{a}}$ y $r{\acute{e}}fl{\acute{e}}chir$; comment, avec l'exemple de la $publicit{\acute{e}}$ jouant la musique $d{\acute{e}}licieuse$ de la gourmandise, nous entrevoyons la $r{\acute{e}}alit{\acute{e}}$ obscure de $l^{\prime}ob{\acute{e}}sit{\acute{e}}$ infantile.

Purpose : Nowadays, drinks, foods and snacks have frequently been intensified with calcium and the insights into the importance of calcium-intake in general has developed in Korea. In this decade, we found the numbers of children who was visited to our hospital for evaluation of hematuria defined with hypercalciuria were increased. So we tried to compare the mean levels of serum calcium, alkaline phosphate, sodium, potassium, chloride, BUN, creatinine, bicarbonate and urinary pH who visited our hospital in 1991, 1992 with in 2000, 2001. Materials and methods : Between January 1991 to December 1992, and between January 2000 to December 2001, each 366 children and 488 children, aged 1 month to 15 years, who presented in our hospital for tonsilectomy and adenoidectomy or for inguinal herniorrhaphy were enrolled in the study, The children in the study were checked the level of serum calcium, alkaline phosphate, sodium, potassium, chloride, BUN, creatinine, bicarbonate and urinary pH with the machine which was corrected the similar levels of practical chemical levels in serum. We compared each mean levels in 1991s' group with in 2001s' group totally and separately through the age and sex. We used t-test to analysis data. Results : The levels of serum calcium, alkaline phosphate, creatinine, sodium, potassium, and urinary pH of 2001s' group were significantly higher than the levels of 1991s' group(P<0.05). The each level was $9.91{\pm}0.50\;mg/dL,\;248.58{\pm}94.98\;U/L,\;0.61{\pm}0.14\;mg/dL,\;138.64{\pm}2.22\;mM/L,\;4.35{\pm}0.40\;mM/L,\;6.18{\pm}0.86$ in 2001s' and $9.13{\pm}0.68;mg/dL,\;198.26{\pm}79.34\;U/L,\;0.433{\pm}0.18\;mg/dL,\;137.86{\pm}2.67\;mM/L,\;4.22{\pm}0.36\;mM/L,\;5.83{\pm}0.95$ in 1991s'. And the levels of serum bicarbonate, $23.64{\pm}2.57\;mM/L$ in 2001s' was significantly lower than the 1991s', $24.60{\pm}2.23\;mM/L$(P<0.05). The similar results were detected each age and sex group. Conclusion : The levels of serum calcium increase in this decade. The results will be used as a basic data for the national health plan in the years to come.

Within the group of congenital cardiac anomalies manifesting dextrocardia and double-outlet right ventricle, ventricular non-inversion [S.D.L] is extremely rare. Recently, a 5 year-old boy underwent a successful surgical correction of dextrocardia associated with double-outlet right ventricle, ventricular non-inversion [S.D], ventricular septal defect, pulmonary stenosis, and patent foramen ovale. The operation consisted of construction of an internal baffle connecting the left ventricle to the aorta through the large ventricular septal defect [subaortic]. The pulmonary stenosis was managed by infundibulectomy and patch enlargement of the right ventricular wall. The patient`s postoperative recovery has been uneventful, and 2 months after the operation, he is doing well.

In this study, the possibility of a quartz crystal micro-balance(QCM) modification of crystallization of L-Penicillamine and D-Penicillamine with a Vapor Diffused Molecular Assembly Technique and its application to the R-(-)-Mandelic acid and S-(+)- Mandelic acid measurement was investigated. The 3-dimensional structures of L-Penicillamine and D-Penicillamine on the surface of QCM were verified to be different from each other through QCM and AFM analyses. The D-Penicillamine modified QCM had specific recognition to the R-(-)-Mandelic acid, but L-Penicillamine modified QCM had no specificity to the R-(-)-Mandelic acid and S-(+)- Mandelic acid. From these results, it was known that the QCM could be modified with various selective meterials via VDMA, and the chiral isomer such as a Mandelic acid isomer could be detected by using a modified QCM.

This study was performed to evaluate the effects of the supplementation of lactic acid bacterias (LAB; S. thermophilus, L. acidophilus) aluminum accumulation and function kidney in rats treated with 250 g/g aluminum sulfate for 4 weeks. Fifty male Sprague Dawley strains were divided into five groups according to the types of supplement. the control, S. thermophilus culture group(A), autoclaved S. thermophilus culture(B), L. acidophilus culture group(C) and autoclaved L. acidophilus(D). The weight gain was increased by supplementation of S. thermophilus culture(A), autoclaved S. thermophilus culture(B), L. acidophilus culture(C), autoclaved L. acidophilus culture(D), especially by supplementation of S. thermophilus cultured(A) as compared to control group. The amount of water intake was increased in control group as compared to the LAB supplemented group. The content of aluminum were decreased 19.57%, 31.25%, 37.10%, and 32.40% in kidney after supplementation of non autoclaved culture group (A,C), and autoclaved group(B,D) respectively, as compared to control group. Water balance, urine volume, and excretion of sodium and potassium decreased in LAB supplemented group and control group. Excretion of creatinine increased in control group and tendency to increased in LAB supplemented group. In conclusion, the effect of suppression of aluminum accumulation was more effective in sup plementation of S. thermophilus culture(A), and L. acidophilus culture(C) than autoclaved S. thermo philus culture(B), and L. acidophilus culture(D).

Vitamin D dependent rickets type 1A (VDDR1A) is an autosomal recessive disorder caused by mutations in CYP27B1. Clinical findings are growth retardation, hypotonia, muscle weakness, hypocalcemic seizures, and radiological features of rickets. We aimed to present the VDDR1A case with a genetic study of CYP27B1. The 14-month-old boy was admitted to the hospital due to a seizure. Serum calcium, phosphorus, alkaline phosphatase, parathyroid hormone (PTH), 25(OH) vitamin D, and 1,25(OH)2 vitamin D values were 5.1 mg/dL, 3.7 mg/dL, 705 IU/L, 429 pg/mL, 24.9 ng/mL, and 8.8 pg/mL, respectively. Radiological study showed cupping and fraying of the distal ulna and radius. The molecular genetic study revealed that the patient had a compound heterozygous mutation, $Phe443Profs^*24$ and c.589+1G>A, in CYP27B1. Genetic analysis of the family members presented that the mother was heterozygous for the mutation c.589+1G>A, and that the father was heterozygous for $Phe443Profs^*24$. The patient was treated with calcium lactate and calcitriol. Until now, six Korean patients with VDDR1A have been studied. Including this case, Korean patients with VDDR1A were found to have only three different mutations in 14 alleles, indicating that the mutation in the CYP27B1 gene is homogeneous in the Korean population.

Porphyra pseudolinearis and P. dentata from Korea were crossed and the hybrid was cultured at different temperatures (5, 10, 15, 20 or $25^{\circ}C$), photon flux densities (10, 20, 40 or 80${\mu}$mol m$^{-2}$s$^{-1}$) under photoperiods (14L:10D and 10L:14D). In the hybrids, the conchocelis grew faster at 2$0^{\circ}C$ and 40$\mu$mol m$^{-2}$ s$^{-1}$ at $25^{\circ}C$ only, and were abundant, when cultured under 10L:14D. Foliose thalli of the hybrid grew rapidly at conditions of 10-2$0^{\circ}C$, 10L:14D and 15-2$0^{\circ}C$, 14L:10D but slowly at 5 and 2$0^{\circ}C$. No archeospores were observed any tested culture condition. Spermatangial and zygotosporangial sori were formed at the marginal portion o mature thallus. Zygotospores from the hybrid were released at 10-2$0^{\circ}C$ under both photoperiods, and gave rise to form conchocelis filament. Monoecious thalli were observed at 1$0^{\circ}C$ under 14L:10D. Neither monospores nor protothalli were produced from the conchocelis in culture.

The green microalgae Chlamydomonas reinhardtti is well-known specie in the terms of $H_2$ production by photo fermentation and has been studying for a long time. Although the $H_2$ production yield is promising; there are some bottlenecks to enhance the yield and efficiency to focus on a well-designed, sustainable production and also scaling up for further studies. D1 protein of photosystem II (PSII) plays an important role in photosystem damage repair and related to $H_2$ production. Because Chlamydomonas is the model algae and the genetic basis is well-studied; metabolic engineering tools are intended to use for enhanced production. Mutations are focused on D1 protein which aims long-lasting hydrogen production by blocking the PSII repair system thus $O_2$ sensitive hydrogenases catalysis hydrogen production for a longer period of time under anaerobic and sulfur deprived conditions. Chlamydomonas CC124 as control strain and D1 mutant strains(D240, D239-40 and D240-41)are cultured photomixotrophically at $80{\mu}mol\;photons\;m^{-2}s^{-1}$, by two sides. Cells are grown in TAP medium as aerobic stage for culture growth; in logarithmic phase cells are transferred from aerobic to an anaerobic and sulfur deprived TAP- S medium and 12 mg/L initial chlorophyll content for $H_2$ production which is monitored by the water columns and later detected by Gas Chromatography. Total produced hydrogen was $82{\pm}10$, $180{\pm}20$, $196{\pm}20$, $290{\pm}30mL$ for CC124, D240, D239-40, D240-41, respectively. $H_2$ production rates for mutant strains was $1.3{\pm}0.5mL/L.h$ meanwhile CC124 showed 2-3 fold lower rate as $0.57{\pm}0.2mL/L.h$. Hydrogen production period was $5{\pm}2days$ for CC124 and mutants showed a longer production time for $9{\pm}2days$. It is seen from the results that $H_2$ productions for mutant strains have a significant effect in terms of productivity, yield and production time.

The water quality of the Keum river was surveyed at 4 sites from April to September in 1995 and 1997. Average values of inorganic contents analyzed in 1997 were pH 7.2, EC 0.18dS/m, $NH_4-N$ 0.60mg/l, $K^+$ 4.12mg/l, $Ca^{2+}$ 12.12 mg/l, $Mg^{2+}$ 2.75mg/l, $Na^+$ 15.1mg/l, $NO_3-N$ 1.97mg/l, $PO_4^{3-}$ 0.15mg/l, $PO_4^-$ 18.9mg/l, $Cl^-$ 21.8mg/l, Fe 0.22mg/l, COD 19.7mg/l. On the basis of these values, it was suitable for the irrigation source. Water pH of the Keum river ranged from 6.7 to 8.0. EC of the Daecheong-dam was maintained below 0.13dS/m, but those of the middle and lower stream were ranged from 0.13dS/m to 0.32dS/m. Monthly average values of all the ration contents were the highest in April and were decreased thereafter. And it was slightly increased in September. However $NO_3-N$, $SO_4^{2-}$ contents were higher in June than any other months. All the inorganic contents were the highest at Taepyeong-ri, Yeongi-gun due to sewage water and livestock wastes. The inorganic contents were negatively correlated with precipitation, generally.

Objective : D-dimer is a breakdown product of fibrin mesh after factor XIII stabilization. Previously, many authors have demonstrated a relationship between D-dimer level and stroke progression or type. This study aimed to investigate the relationship between D-dimer level and stroke volume. Methods : Between January 2008 and December 2009, we analyzed the D-dimer levels of 59 acute ischemic stroke patients in our neurosurgical department both upon admission and after seven days of initial treatment. Each patient's National Institute of Health Stroke Scale score, modified Rankin Scales score, Glasgow outcome score, and infarction volume were also evaluated. Results : Mean D-dimer level at admission was 626.6 ${\mu}g/L$ (range, 77-4,752 ${\mu}g/L$) and the mean level measured after seven days of treatment was 238.3 ${\mu}g/L$ (range, 50-924 ${\mu}g/L$). Mean D-dimer level at admission was 215.3 ${\mu}g/L$ in patients with focal infarctions, 385.7 ${\mu}g/L$ in patients with multiple embolic infarctions, 566.2 ${\mu}g/L$ in those with 1-19 cc infarctions, 668.8 ${\mu}g/L$ in 20-49 cc infarctions, 702.5 ${\mu}g/L$ in 50-199 cc infarctions, and 844.0 ${\mu}g/L$ in >200 cc infarctions (p=0.044). On the 7th day of treatment, the D-dimer levels had fallen to 201.0 ${\mu}g/L$, 293.2 ${\mu}g/L$, 272.0 ${\mu}g/L$, 232.8 ${\mu}g/L$, 336.6 ${\mu}g/L$, and 180.0 ${\mu}g/L$, respectively (p=0.530). Conclusion : Our study shows that D-dimer level has the positive correlation with infarction volume and can be use to predict infarction-volume.
