  • Consumption of pepper, a major spice vegetable used for seasoning Kimchi, continues to increase, but cultivation is in decline due to shortage of rural labor in Korea. The 39.2% of total labor requirement for conventional pepper cultivation was available for harvesting work. Therefore conventional manual harvesting should be turned to mechanical harvesting for labor-saving, cost-reducing and easy work. Surveys on conventional pepper cultivation patterns, labor requirements for various pepper cultivation works, and farmers' opinions on the mechanization of pepper harvesting were conducted to obtain basic informations. The labor requirement for pepper harvesting was 954 h/ha out of a total labor requirement of 2,436 h/ha for pepper cultivation. Harvesting was the hardest work, and hiring workmen for harvesting was also difficult. Farmers preferred to develop a small-scale pepper harvester using agricultural tractor or cultivar. Most farmer agreed to change cultivation pattern for mechanization of pepper harvesting, but hesitated to adopt new one-time-harvesting pepper varieties.

  • 최근 정보화 프로젝트 수행 능력에 대한 객관적인 검증이 필요하다는 판단에 따라 SI 업계에서는 프로젝트 품질 평가 심사 모형인 CMM 및 SPICE의 등급 인증 획득 또는 등급을 올리기 위한 노력을 기울이고 있다. 공공기관, 민간 발주처들이 사업자의 프로젝트 수행능력에 대한 객관적인 검증을 요구하고 있고, 해외 IT 업체들의 국내 시장 공략에도 효율적으로 대처할 수 있다는 판단에 따라 프로젝트 품질 평가 심사 모형 인증 도입이 확산되고 있다. 그러나 인증의 신뢰성에 대하여 논란이 되고 있는 시점에서 등급을 인증받은 기관이 비 인증기관보다 품질 및 성과에 차이를 보이는지 연구하였다. 연구 결과 현저하게 큰 차이는 아니며 부분적으로 차이가 있는 것으로 나타났다. 국내업체들이 CMM 인증 자체에만 집착하지 말고 컨설팅을 통한 업무 프로세스 개선과정에 의미를 두고 인증에 힘을 기울여야 한다. 즉, 품질인증의 획득 목표가 인증서 획득만이 목표가 아니라 진정한 프로젝트 품질 시스템의 구축, 실현하는 품질 마인드가 우선적으로 제고되어야 말 것이다.

  • Ginger (Zingiber of oficinale Roscoe, Zingiberaceae) is one of the most frequently and heavily consumed dietary condiments throughout the world. Besides its extensive use as a spice, the rhizome of ginger has also been used in traditional oriental herbal medicine for the management of symptoms such as common cold, digestive disorders, rheumatism, neurologia, colic, and motion-sickness. The oleoresin from rhizomes of ginger contains [6] -gingerol (1- [4'-hydroxy-3'-methoxyphenyl]-5-hydroxy-3-decanone) and its homologs as pungent ingredients that have been found to possess many interesting pharmacological and physiological activities, such as anti-inflammatory, analgesic, antipyretic, antiheatotoxic, and cardiotonic effects. However, the effect of [6]-gingerol on cell proliferation in breast cancer cell are not currently well known. Therefore, in this study, we examined effect of [6]-gingerol on protein and mRNA expression associated with cell proliferation in MDA-MB-231 human breast. cancer cell lines. We cultured MDA-MB-231 cells in presence of 0, 2.5, 5 and $10{\mu}M$ of [6] -gingerol. [6]-Gingerol inhibited breast cancer cell growth in a dose-depenent manner as determined by MTT assay. ErbB2 and ErbB3 protein and mRNA expression were decreased dose-dependently in cells treated with [6]-gingerol (p<0.05). In addition, phosphorylated Akt levels and total hぉ levels were markedly decreased in cells treated with $2.5{\mu}M$ [6]-gingerol (p<0.05). In conclusion, we have shown that [6]-gingerol inhibits cell proliferation through ErbB2 and ErbB3, reduction in MDA-MB-231 human breast cancer cell lines.

  • Ginger, one of worldwide consumed dietary spice, is not only famous as food supplements, but also believed to exert a variety of remarkable pharmacological activity as herbal remedies. In this study, a ginger constituent, 12-dehydrogingerdione (DHGD) was proven that has comparable anti-inflammatory activity with positive control 6-shogaol in inhibiting LPS-induced interleukin (IL)-6, tumor necrosis factor $(TNF)-{\alpha}$, prostaglandin (PG) $E_2$, nitric oxide (NO), inducible NO synthase (iNOS) and cyclooxygenase (COX)-2, without interfering with COX-1 in cultured microglial cells. Subsequent mechanistic studies indicate that 12-DHGD may inhibit neuro-inflammation through suppressing the LPS-activated $Akt/IKK/NF-{\kappa}B$ pathway. Furthermore, 12-DHGD markedly promoted the activation of NF-E2-related factor (Nrf)-2 and heme oxygenase (HO)-1, and we demonstrated that the involvement of HO-1 on the production of pro-inflammatory mediators such as NO and $TNF-{\alpha}$ by using a HO-1 inhibitor, Zinc protoporphyrin (Znpp). These results indicate that 12-DHGD may protect against neuro-inflammation by inhibiting $Akt/IKK/I{\kappa}B/NF-{\kappa}B$ pathway and promoting Nrf-2/HO-1 pathway.

  • BACKGROUND/OBJECTIVES: Excessive alcohol consumption has harmful health effects, including alcohol hangovers and alcohol-related liver disease. Therefore, methods to accelerate the alcohol metabolism are needed. Laurus nobilis is a spice, flavoring agent, and traditional herbal medicine against various diseases. This study examined whether the standardized aqueous extract of L. nobilis leaves (LN) accelerates the alcohol metabolism and protects against liver damage in single-ethanol binge Sprague-Dawley (SD) rats. MATERIALS/METHODS: LN was administered orally to SD rats 1 h before ethanol administration (3 g/kg body weight [BW]) at 100 and 300 mg/kg BW. Blood samples were collected 0.5, 1, 2, and 4 h after ethanol administration. The livers were excised 1 h after ethanol administration to determine the hepatic enzyme activity. The alcohol dehydrogenase (ADH), aldehyde dehydrogenase (ALDH), superoxide dismutase (SOD), and glutathione peroxidase (GPx) activities in the liver tissue were measured. RESULTS: LN decreased the serum ethanol and acetaldehyde levels in ethanol-administered rats. LN increased the hepatic ADH and ALDH activities but decreased the alanine aminotransferase, aspartate aminotransferase, and gamma-glutamyl transferase activities in the ethanol-administered rats. In addition, LN inhibited lipid peroxidation and increased the activities of SOD and GPx. CONCLUSIONS: LN modulates the mediators of various etiological effects of excessive alcohol consumption and enhances the alcohol metabolism and antioxidant activity, making it a potential candidate for hangover treatments.
