The purpose of this study is to finding out how ICT can be used effectively in teaching. The subject under study is Mathematics. The study started with analyzing literature on how Mathematics is being taught in Korea. This throughout the paper acts as a springboard to set a precedent for Mali Education progress. Facts about teaching mathematics using ICT were backed up by an interview with an elementary teacher. EDUNET materials and multimedia flash as the basic resources teachers use are discussed in the paper. As a results, we found which will be used to improve the teaching in general and mathematics: (i) particularly establish an ICT policy; (ii) set up infrastructure with computer facilities; (iii) build the competence levels of the teachers in basic ICT skills; (iv) educate the stakeholders on the benefits of ICT using in teaching; (v) develop a program that can enable teachers to teach using ICT; (vi) Develop materials to use when teaching; (vii) use various ICT resources when teaching; and (viii) balance off -line and on-line teaching.

The relationship between three phenological parameters and somatic embryogenesis was investigated during a two-year period. Staminodes and petals from six hybrids and two clones as controls were sowed on three distinct primary callus growth media. Flowering level, fructification level, and leaf thrusts rhythm as phenological parameters were measured simultaneously during the weekly harvest of flower buds. Mean and coefficient of variation of the measured parameters highlighted stable phenological phases. The relationship between phenological parameters and somatic embryogenesis was investigated first by comparing the variation of somatic embryogenesis and that of the phenological parameters, and second by using Pearson's linear correlation. Except for the fructification level in both control clones the first year, the other parameters recorded stable phenological phases, regardless of the genotype and year. Favorable and unfavorable phases for the somatic embryogenesis were identified. In hybrids, favorable phases included February, August, September, and October. In both control clones, time interval propitious to embryogenesis stretched from February to December. The significance of the coefficient of correlation seemed to establish a relationship between somatic embryogenesis and phenology. However, a causal link could not be established. Leaf thrusts rhythm was revealed to be the phenological parameter most linked to somatic embryogenesis. Attempts to optimize embryogenesis during unfavorable phases, showed that a correction of 2.4 D/TDZ concentration is not the solution.

Bilateral distal femoral epiphyseal detachment in a young adult: a case report

( Armand Yepie ),( Moctar Traore ),( Mensah Yaovi ),( Michel Anoumou ) 대한외상학회 2023 大韓外傷學會誌 Vol.36 No.4

Epiphyseal dislocations and fractures frequently occur in children and adolescents. However, these injuries seldom involve the distal femur, and bilateral cases are even rarer. We present an unusual case of bilateral epiphyseal detachment of the femur in a 21-year-old man who was involved in a traffic accident. Open reduction and fixation surgery were performed 5 days after the incident. The patient experienced favorable progress, with consolidation occurring at 3 months. No lower limb length discrepancies were observed at the 20-month follow-up. In summary, bilateral distal femoral epiphyseal detachment is an uncommon condition that can be effectively treated through surgical intervention.

Analysis of Covert Hardware Attacks

Samer Moein,Fayez Gebali,Issa Traore 한국정보기술융합학회 2014 JoC Vol.5 No.3

Current embedded system, such as cell phones and smart-cards, in corporate security devices or cryptographic processor. These cryptographic devices often store private keys or other sensitive data, so compromise of this data or the underlying hardware may lead to loss of privacy, forged access, or monetary theft. Even if the attackers fail to gain the secret information that is stored in a hardware, they may be able to disrupt the hardware or deny service leading to other kinds of security failures in the system. Therefore hardware attacks targets this security devices. Hardware attacks could be covert or overt based on awareness of the targeted system. This paper reviews proposed Accessibility/Resources/Time (ART) schema that quantifies hardware attacks. We focus in this paper on presenting covert attacks and quantify the attack using the ART schema.

Background: Breast cancer is a heterogeneous disease that represents a major public health problem. The immunohistochemical determination of breast cancer subtypes with regard to estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor (HER2) status can contribute to improved selection of therapy and patientcare. The purpose of this study was to determine the prevalence of the molecular breast cancer subtypes and to assess their associations with classical clinicopathologic parameters for better therapeutic decisions in women with breast cancer in the Ivory Coast. Materials and Methods: Formalin-fixed and paraffin-embedded blocks of patients diagnosed with primary breast carcinoma were subjected to immunohistochemical assay for the assessment of ER/RP and HER2 expression. The one-way analysis of variance evaluated the difference between breast cancer subtypes and mean age of patients. The Chi-square Test was used to compare standard clinicopathologic prognostic parameters with tumor subtypes. Results. Among 302 patients, 57% were premenopausal and 43% were postmenopausal. The invasive ductal carcinoma not otherwise specified (IDC NOS) (82.8%) was the most frequent histological type, and the tumor grade 2 (56%) was predominant followed by grade 3 (20.9%). The proportion of positivity of ER, PR, and HER2 was 56%, 49%, and 15.6%, respectively. Half of patients of this study (51.6%) had luminal A breast tumor type followed by TN (32.1%). Other subtypes were luminal B (10.1% ) and non-luminal HER2+ (6.3%). Conclusions. The findings of the present study are in line with the literature and should assist in management of breast cancer in our country.

The relative lack of information on breast cancer etiology in Burkina Faso led us to undertake the present work to highlight risk factors. This prospective study was conducted using a questionnaire between January 2015 and February 2016 on women admitted to Yalgado OUEDRAOGO hospital, for consultation or supervision. The characteristics of multiparous breast cancer patients (n = 44) were compared with their non-multiparous counterparts (n = 36). The study found that increased risk of breast cancer among non-multiparous cases was related to body mass index (BMI) (p <0.001), age at menopause (p <0.004) and use of oral contraception (p <0.021) while abortion (p <0.002) was a risk factor among multiparous cases. These results suggest that even if multiparity is associated with a decreased risk in some women, avoidance of abortion during reproductive life should be recommended. The results provide preliminary information, which now need to be supplemented by survey of a larger sample in the national territory.

Measuring Agricultural Trade Integration in Southeast Asia

Antoine Bouët,Aziz Elbehri,Duc Bao Nguyen,Fousseini Traoré 세종대학교 경제통합연구소 2022 Journal of Economic Integration Vol.37 No.2

This paper offers an evaluation of agricultural trade integration in Southeast Asia. Since the ultimate objective is to provide policy recommendations, the indicators presented include those obtained from a measurement based on trade barriers: tariffs applied on imports, tariffs faced by exports, customs procedures and trade facilitation measures, and nontariff measures. A new estimation of the trade impact of nontariff measures in the agrifood sector is provided, based on refinements to the methodology of Kee, Nicita, and Olarreaga (2009) and Ghodsi, Grübler, and Stehrer (2016a). Globally, the Southeast Asian region appears to be relatively open to the world, but regional integration could be strengthened, particularly in the agriculture and food sectors. Specifically, a convergence of Sanitary and Phytosanitary measures and Technical Barriers to Trade measures could achieve more integration.
