African Businesswomen in Asia : A Cultural Interface in the World of Globalization
Rebecca Mbuh Research Institute of Asian Women Sookmyung Women' 2005 Asian Women Vol.21 No.-
This paper explores the expansion of African women's business practices from the local environment to the international arena. Though African women have been engaged in trading from time immemorial, the venture into transcontinental trading is a phenomenon which is only now gaining more visibility. Due to persistent economic hardships which began in the 1990s, many African women are taking advantage of the benefits of globalization and modern technologies to engage in international trade. While the benefits and rewards are gratifying, there are several challenges that these women face. Through detailed interviews conducted with selected women who trade between African countries and Asia, especially Korea, some of the difficulties and opportunities are highlighted. These challenges are experienced at two fronts: in their home countries and internationally as they share time between family responsibilities and their businesses.
Globalization, Women, and Business : A Study of the Adaptation of African Businesswomen in Korea
Rebecca N. Mbuh 숙명여자대학교 아시아여성연구원 2007 Asian Women Vol.23 No.2
With the embracing of globalization, nations have seen a significant increase in women’s international business participation. Several factors contributed to this shift including improvements or modifications in many national policies, improvements in gender equality laws allowing many African women to engage in business and travel without approval or permission from their husbands, huge reductions in national spending, and an overall declining world economy. Traditionally, the vast majority of people migrating voluntarily have been men. At the start of this new century, the number of women migrants has increased significantly. While many African migrants favor the western countries because of the proximity and ease of getting there, the numbers choosing to migrate to Asian countries is on the rise. The focus of this paper is on African businesswomen in Korea. Specifically, this paper examines reasons for migrating to Korea, challenges/opportunities encountered and coping strategies. Economic opportunities emerged as the main reason for migrating. Other reasons including seeking peace of mind, seeking to start a new life, and running from in-laws were also cited by both the married and unmarried participants in the study.
Inhibition of Protein Glycation by Extracts of Culinary Herbs and Spices

We tested whether polyphenolic substances in extracts of commercial culinary herbs and spices would inhibitfructose-mediated protein glycation. Extracts of 24 herbs and spices from a local supermarket were tested for the ability toinhibit glycation of albumin. Dry samples were ground and extracted with 10 volumes of 50% ethanol, and total phenoliccontent and ferric reducing antioxidant potential (FRAP) were measured. Aliquots were incubated in triplicate at pH 7.4 with0.25 M fructose and 10 mg/mL fatty acid-free bovine albumin. Fluorescence at 370 nm/440 nm was used as an index of al-bumin glycation. In general, spice extracts inhibited glycation more than herb extracts, but inhibition was correlated with to-tal phenolic content (R2 . 0.89). The most potent inhibitors included extracts of cloves, ground Jamaican allspice, and cin-namon. Potent herbs tested included sage, marjoram, tarragon, and rosemary. Total phenolics were highly correlated withFRAP values (R2 . 0.93). The concentration of phenolics that inhibited glycation by 50% was typically 412 .g/mL. Rela-tive to total phenolic concentration, extracts of powdered ginger and bay leaf were less effective than expected, and blackpepper was more effective. Prevention of protein glycation is an example of the antidiabetic potential for bioactive compoundsin culinary herbs and spices.
Hollowness Variation with Die Wall Thickness in Melt-Spinning of Polypropylene Hollow Fibers
Rebecca Ruckdashel,심은경 한국섬유공학회 2022 Fibers and polymers Vol.23 No.5
A hollow fiber poses great potential as it can provide superior performance at low weight and low cost. Its uniqueproperties come from its geometry, the presence of void and air inclusion, but controlling it is a challenging problem. Thisstudy explores how the geometry of a die influences fiber hollowness. Fibers were extruded from dies with four segmentedarcs, 4-C, which had varying die wall thickness and constant inner diameter. The effects of die wall thickness on wall-shearrate, solidification, spinnability, and hollow fiber geometry are evaluated under various processing conditions. Bothprocessing parameters and die wall thickness influence hollow fiber dimensions and hollowness, but die wall thickness hasthe largest impact. Reduction of die wall thickness decreases fiber wall thickness, increases the outer and inner diameter, andincreases hollowness. It can be explained by higher die hollowness and faster extrudate solidification. However, the thinnestdie shows reduced spinnability.

Paraneoplastic neurologic diseases (PND) are rare but can occur in patients with common malignancies including breast cancer. In patients with hormone receptor (HR)-negative human epidermal growth factor receptor 2 (HER2)-positive breast cancer, PND have been reported in association with anti-Yo antibodies and with clinical presentation of paraneoplastic cerebellar degeneration. We describe the case of a woman with progressively altered mental status and seizures, ultimately requiring admission. Based on her clinical presentation, imaging findings, and evidence of neural-directed antibodies in her serum and cerebrospinal fluid, she was diagnosed with paraneoplastic limbic encephalitis (LE) due to an underlying HR-negative, HER2-positive breast cancer. She showed a transient response to immunosuppression but had more significant improvement after surgical resection and initiation of chemotherapy along with HER2-directed therapy. To the best of our knowledge, this is the first documented case of paraneoplastic LE in a patient with HR-negative, HER2-positive breast cancer likely caused by the production of an unclassified anti-neuronal antibody.
Neuropathologic features of central nervous system hemangioblastoma
Rebecca A. Yoda,Patrick J. Cimino 대한병리학회 2022 Journal of Pathology and Translational Medicine Vol.56 No.3
Hemangioblastoma is a benign, highly vascularized neoplasm of the central nervous system (CNS). This tumor is associated with loss of function of the VHL gene and demonstrates frequent occurrence in von Hippel-Lindau (VHL) disease. While this entity is designated CNS World Health Organization grade 1, due to its predilection for the cerebellum, brainstem, and spinal cord, it is still an important cause of morbidity and mortality in affected patients. Recognition and accurate diagnosis of hemangioblastoma is essential for the practice of surgical neuropathology. Other CNS neoplasms, including several tumors associated with VHL disease, may present as histologic mimics, making diagnosis challenging. We outline key clinical and radiologic features, pathophysiology, treatment modalities, and prognostic information for hemangioblastoma, and provide a thorough review of the gross, microscopic, immunophenotypic, and molecular features used to guide diagnosis.
