  • While nitric oxide (NO) produced by inducible nitric oxide synthase (iNOS) is beneficial for host survival, it is also detrimental to the host. Thus, regulation of iNOS gene expression may be an effective therapeutic strategy for the prevention of unwanted reactions at various pathologic conditions. During the screening process for the possible iNOS regulators, we observed that esculetin is a potent inhibitor of cytokine-induced iNOS expression. The treatment of 3T3-L1 adipocytes with the tumor necrosis factor-${\alpha}$ (TNF) induced iNOS expression, leading to enhanced NO production. TNF-induced NO production was inhibited by esculetin in a dose-dependent manner. Esculetin inhibited the TNF-induced NO production at the transcriptional level through suppression of iNOS mRNA and subsequent iNOS protein expression. These results suggest esculetin, a component of natural products, as a naturally occurring, nontoxic means to attenuate iNOS expression and NO-mediated cytotoxicity.

  • Since the mid-1980's, strategic alliances are dominantly hailed as an effective growth and survival strategy in the era of international market and multinational corporation. There are a number of reasons for this phenomenon. there is an increasing globalization of markets in an ever-widening band of industries, together with the development of global technologies that makes production cycles shorten and the ever-increasing demand for investment resources and information to cope with the changing environment. The purpose of this study is to investigate the determinants of corporation information system in strategic alliance mode, and to analyze the main factors which are affecting the choice of strategic alliance mode by Korean firms. This study can also contribute theoretical and practical suggestive points in relation to strategic alliance operations. However, it also has limits as an exploratory study due to lacks of prior studies and proper methodologies and so on. Accordingly, the phenomenon of international strategic alliances call for further studies on casual relationships between main factors and variables in this field.

  • After 6 Sigma administration is introduced in domestic in 1997, many corporations are utilizing by survival strategy and method of administration reform. This is applied in all field that this led to R&D from service industry by the next. Success factors by each field was studied and announced applying in various types of business. The Korail and Korea Post, the Ministry of Environment and various public corporation and governmen and municipal office are introduce and utilizing 6 Sigma administration by innovation method present. But, research about success factor that special quality of public sector is considered up to now was almost no. This treatise analyzed 6 Sigma' success factors and effect relation to public corporation.

  • Well-differentiated thyroid cancer is the most common endocrine malignancy with an increasing incidence. Most patients with well-differentiated thyroid caner have a favorable prognosis with high survival rate. While surgery and radioiodine therapy is sufficient treatment for the majority of patients with differentiated thyroid cancer, a minority of these patients experiences progressive, life-threatening growth and metastatic spread of the disease. Because there is no prospective controlled study to evaluate the differences of management of thyroid cancer, it is hard to choose the best treatment option. And there are still lots of controversies about the management of this disease, such as surgical extent, proper use of radioiodine for remnant ablation and therapy, use of rhTSH instead of withdrawal of thyroid hormone, long-term follow-up strategy, thyroglobulin as a tumor marker, etc. In this review, recent data related to these conflicting issues and recent advances in diagnosis, radioiodine therapy and long-term monitoring of well-differentiated thyroid cancer are summarized.

  • Ceratopteris thalictroides is a semi-aquatic fern with a circumtropical distribution. Because this species is designated internationally on the IUCN Red List as requiring at least some concern, Korean populations are of great concern for the species' long-term survival, as they are at the northern limit of the species distribution. To establish an effective conservation strategy for those populations at the genetic level, we used the Mi-Seq platform to develop three sets of 25 polymorphic microsatellite markers for C. thalictroides, which is endangered in Korea. In populations sampled from Busan and Gochang, the number of alleles ranged from 2 to 13 (average of 5.64), and plants presented an expected heterozygosity of 0.000 to 0.860. These markers will be useful for evaluating the genetic status and conserving Korean populations of C. thalictroides more effectively.

  • Due to rapid environmental-change pharmaceutical industry, sales strategy for sales survival of pharmaceutical company is necessary. In accordance with the rapid development of medicine and advancement of efforts to secure the market, competition among pharmaceutical companies make an effort to achieve their goals. However, due to various negative influence of inside and outside, this field is getting a difficult occupation. Even when securing and training new employees with quite a bit of expense and time, the rate of surviving employees over 1 year is decreasing. For this, the researcher suggested major research result through actual investigation by utilizing survey technique, and a plan to enhance pharmaceutical company salespersons' core competence and raise sales achievement. As the research result, company culture strongly influences salespersons' sales ability. We defined the formation of organizational culture, which influences communication culture where smooth communication is made in the company, also, definite and exact evaluation in promoting work, and trust formation between upper and lower organization, is important, which should be reflected in the company field.

  • Membrane-anchored full-length MET stimulated by its ligand HGF/SF induces various biological responses, including survival, growth, and invasion. This panel of responses, referred to invasive growth, is required for embryogenesis and tissue regeneration in adults. On the contrary, MET deregulation is associated with tumorigenesis in many kinds of cancer. In addition to its well-documented ligand-stimulated downstream signaling, the receptor can be cleaved by proteases such as secretases, caspases, and calpains. These cleavages are involved either in MET receptor inactivation or, more interestingly, in generating active fragments that can modify cell fate. For instance, MET fragments can promote cell death or invasion. Given a large number of proteases capable of cleaving MET, this receptor appears as a prototype of proteolytic-cleavage-regulated receptor tyrosine kinase. In this review, we describe and discuss the mechanisms and consequences, both physiological and pathological, of MET proteolytic cleavages.
