PRAKTIK POLIGAMI DALAM DRAMA KOREA MR. QUEEN: KAJIAN CDA TEUN A VAN DIJK
Drama Korea Mr. Queen tidak hanya mengisahkan intrik perebutan kekuasaan tetapi juga terdapat adanya praktik poligami yang dilakukan oleh Raja Joseon. Kisah tersebut menarik untuk dikaji mengingat poligami identik dengan ajaran Islam. Namun, pada drakor Mr Queen juga terdapat adanya praktik poligami. Penelitian ini memiliki tujuan untuk menemukan dan mendeskripsikan struktur makro dan struktur mikro praktik poligami yang dilakukan oleh Raja Cheoljong dalam drama Korea Mr. Queen. Sifat penelitian yaitu deskriptif kualitatif dengan memanfaatkan teori analisis model Teun A van Dijk untuk membedahnya dengan pendekatan objektif. Data berupa penggalan teks dengan sumber data penelitian drama Korea Mr Queen yang ditayangkan di Saluran lokal TvN yang ada di Korea.

Temuan dalam penelitian ini yaitu struktur makro (tematik), stuktur mikro semantik (latar, detail, dan maksud), dan stilistik. Penelitian ini memiliki kesimpulan yaitu struktur makro dan struktur mikro yang terdapat di dalam drama Korea Mr. Queen menunjukkan ideologi penulis skenario tentang adanya praktik poligami melalui pilihan kata, struktur kalimat dan alur cerita yang disajikan.
Concentrated Ownership and Corporate Control: Wallenberg Sphere and Samsung Group
Samsung Group’s success cannot be attributed to its corporate governance structure, at least thus far. The corporate governance of Samsung has been rather controversial. As the group faces the succession issue the corporate governance has become as crucial as their new products and services. Samsung has discovered a role model on the other side of the planet, Wallenberg Sphere in Sweden. Much effort has been made to learn about Wallenberg’s arrangements and key to its success. However, a fundamental difference between the institutions in Sweden and Korea has made the corporate structures of the two groups radically different. Wallenberg uses the dual-class commons whereas Samsung relies upon the circular shareholdings through affiliated firms. This Essay explains and analyzes the two different institutions and corporate structures, and argues that the introduction of the dual-class commons in Korea would make the corporate governance of Samsung more transparent and efficient, if and only if accompanied by Samsung’s commitment to socially responsible corporate citizenship. This Essay also explains and analyzes the recent developments in corporate governance of non-banking financial institutions in Korea and looks into the issue from the perspective of Samsung’s structure in comparison with Wallenberg’s structure
Private Enforcement of Company Law and Securities Regulation in Korea
This chapter offers a brief overview of the private enforcement of corporate law and securities regulation in Korea, with particular reference to the current legislative efforts in the Korean National Assembly and recent court cases. This chapter also talks about Korea’s ill-fated and misguided adoption of the fraud-on-the-market theory in securities fraud litigation

Red pepper seed water extract inhibits preadipocyte differentiation and induces mature adipocyte apoptosis in 3T3-L1 cells
BACKGROUND/OBJECTIVES: Reducing the number of adipocytes by inducing apoptosis of mature adipocytes as well as suppressing differentiation of preadipocytes plays an important role in preventing obesity. This study examines the anti-adipogenic and pro-apoptotic effect of red pepper seed water extract (RPS) prepared at 4°C (RPS4) in 3T3-L1 cells.
MATERIALS/METHODS: Effect of RPS4 or its fractions on lipid accumulation was determined in 3T3-L1 cells using oil red O (ORO) staining. The expressions of AMP-activated protein kinase (AMPK) and adipogenic associated proteins [peroxisome proliferator-activated receptor-γ (PPAR-γ), CCAAT/enhancer-binding proteins α (C/EBP α), sterol regulatory element binding protein-1c (SREBP-1c), fatty acid synthase (FAS), and acetyl-CoA carboxylase (ACC)] were measured in 3T3-L1 cells treated with RPS4. Apoptosis and the expression of Akt and Bcl-2 family proteins [B-cell lymphoma 2 (Bcl-2), Bcl-2-associated death promoter (Bad), Bcl-2 like protein 4 (Bax), Bal-2 homologous antagonist/killer (Bak)] were measured in mature 3T3-L1 cells treated with RPS4.
RESULTS: Treatment of RPS4 (0-75 ug/mL) or its fractions (0-50 ug/mL) for 24 h did not have an apparent cytotoxicity on pre and mature 3T3-L1 cells. RPS4 significantly suppressed differentiation and cellular lipid accumulation by increasing the phosphorylation of AMPK and reducing the expression of PPAR-γ, C/EBP α, SREBP-1c, FAS, and ACC. In addition, all fractions except ethyl acetate fraction significantly suppressed cellular lipid accumulation. RPS4 induced the apoptosis of mature adipocytes by hypophosphorylating Akt, increasing the expression of the pro-apoptotic proteins, Bak, Bax, and Bad, and reducing the expression of the anti-apoptotic proteins, Bcl-2 and p-Bad.
CONCLUSIONS: These finding suggest that RPS4 can reduce the numbers as well as the size of adipocytes and might useful for preventing and treating obesity
Favoritism and Corporate Law: The Confused Corporate Opportunity Doctrine in the Hyundai Motor Case
Core legal principles of U.S. corporate law are often met with perplexity in foreign jurisdictions – this is especially true when a particular principle remains controversial even in the U.S. This Article takes the corporate opportunity doctrine and examines how it has been exported to the civil law regime in Korea. Korean conglomerates such as Samsung Group and Hyundai Motor Group have become major players in the global market, but corporate law and practice in Korea have had a difficult time keeping up with the developments in the business sector. The Hyundai Motor Case demonstrates an ambitious but ill-fated attempt at adoption of U.S. corporate legal doctrine in Korea. This Article explains and analyzes the case and the new codified corporate opportunity doctrine rule in the Korean Commercial Code from a comparative perspective, and suggests that the dialogue surrounding the corporate opportunity doctrine in Korean legal and business communities are oriented in the wrong direction and that the new rule needs substantial refinement
St. John’s Wort Regulates Proliferation and Apoptosis in MCF-7 Human Breast Cancer Cells by Inhibiting AMPK/mTOR and Activating the Mitochondrial Pathway
St. John’s Wort (SJW) has been used as an estrogen agonist in the systems affected by menopause. Also, hypericin, a bioactive compound of SJW, has been used as a photosensitizer in photodynamic therapy. In the present study, we investigate the anti-proliferative and pro-apoptotic effects of SJWto demonstrate the chemo-preventive effect in human breast cancer cells. MCF-7 cellswere culturedwith DMSO or various concentrations of SJWethanol extract (SJWE). Cell viability, proliferation, apoptosis, the expression of proteins involved in cell growth and apoptosis, and caspase-3/7 activity were examined. SJWE dose-dependently suppressed cell growth and induced apoptosis ofMCF-7 cells. Mechanistically, SJWE enhanced the phosphorylation of AMP-activated protein kinase (AMPK) and decreased the expression of p-mammalian target of rapamycin (p-mTOR) and p-eukaryotic translation initiation factor 4E (eIF4E)-binding protein 1 (4E-BP1). Also, SJWE inhibited the phosphorylation of protein kinase B (Akt) and showed increases in the expression of pro-apoptotic proteins Bax and Bad with decreases in the expression of anti-apoptotic proteins including B-cell lymphoma 2 (Bcl-2), B-cell lymphoma-extra large (Bcl-xL), and p-Bcl-2-associated death promoter (p-Bad). SJWE at 50 µg/mL showed markedly enhanced caspase-7 activation. Taken together, our results provide evidence that SJWE shows anti-proliferative and pro-apoptotic effects via inhibition of AMPK/mTOR and activation of a mitochondrial pathway. Therefore, SJWE can be used as a chemo-preventive agent without photo-activation
