  • The objective of this study was to determine the effect of antioxidant enzyme activity and radical scavenging activities of cucumber grown greenhouse. The analytic method of antioxidant activities were measured by estimating DPPH free radical scavenging, nitrite scavenging ability activity and ABTS radical scavenging ability. The DPPH free radical scavenging activity of Jangjukcheongjang was the highest in most of the growth stage. The Nitrite scavenging ability at pH 1.2 was more than 40% in all cultivars and growth stages. The ABTS radical scavenging ability of Jangjukcheongjang and Nulpureuncheongjang showed relatively little higher than Janghyeongnakhap and Sinjoeunbaekdadagi. The SOD activity showed higher activity than 95% in all cultivars and growth stages. The activity of CAT was highest in the Nulpureuncheongjang of 2 (12~16cm) growth stage, and the APX activity of Nulpureuncheongjang and Janghyeongnakhap showed a relatively high activity. The POX activity showed distinctly different trends depending on the growth stage, and that is, the activity at harvest stage was significantly reduced. These results suggest that the cucumber had the potent biological activities, and that in the future, the availability of cucumber will be increase in the field of high-value cosmetic and food products.

  • Jatropha curcas L. is an oil bearing species with many uses and considerable economic potential as a biofuel crop. Salt stress effect on growth, ion accumulation, contents of protein, proline and antioxidant enzymes activity was determined in callus and seedling to understand the salt tolerance of the species. Exposure of callus and seedling to salt stress reduced growth in a concentration dependent manner. Under salt stress Na content increased significantly in both callus and seedling whereas, differential accumulation in the contents of K, Ca, and Mg was observed in callus and seedling. Soluble protein content differed significantly in callus as compared to seedling, however proline accumulation remained more or less constant with treatments. The proline concentration was ~2 to 3 times more in callus than in seedling. Salt stress induced qualitative and quantitative differences in superoxide dismutase (SOD; E.C. 1.15.1.1) and peroxidase (POX; E.C. 1.11.1.7) in callus and seedling. Salt induced changes of the recorded parameters were discussed in relation to salinity tolerance.

  • Poultry production in korea is a very complex situation. Large modernized farms and old styles of small farming coexist with one another. This gives rise to a tangled epidemiological situation in terms of infectious diseases. The main poultry diseases of economic importance are colibacillosis, pullorum diseases, Mycoplasma gallisepticum infection, infectious coryza, infectious synovitis, Newcasyle disease, fowl pox, Marek's disease, avian encephalomyelitis, infectious bursal disease, infectious laryngotracheitis, infectious bronchitis and coccidiosis. Avian influenza, fowl cholera and fowl typhoid have not been reported for a few decades, and these are rated as exotic diseases.

  • Kaiso is a Pox Virus and Zinc Finger (POZ-ZF) transcription factor with bi-modal DNA-binding specificity. Here, we demonstrated that Kaiso expression is inversely correlated with glucocorticoid receptor (GR) expression in breast carcinomas. Knockdown of Kaiso increased GR expression, while overexpression of Kaiso inhibited GR expression in breast cancer cells. Furthermore, Kaiso repressed GR proximal promoter-reporter activity in a dose-dependent manner. Remarkably, ChIP experiments demonstrated that endogenous Kaiso was associated with the GR promoter sequence in a methylation-dependent manner. Since glucocorticoids inhibit chemotherapyinduced apoptosis and have been widely used as a co-treatment of patients with breast cancer, we assessed the role of Kasio in GR-mediated anti-apoptotic effects. We found that overexpression of Kaiso attenuated the anti-apoptotic effects of glucocorticoids in breast cancer cells. Our findings suggest that GR is a putative target gene of Kaiso and suggest Kaiso to be a potential therapeutic target in GC-combination chemotherapy in breast cancer.

  • Basic summary of the medical administration : Due to Qing dynasty being the last of the dynastic era, it revealed overall extreme political traits in politics, economy, phenomenon, and cultural aspects. Few emperors of the early Qing dynasty adopted appeasement policy that mitigated ironies to a certain extent and showed growth in various business related fields. Even the medical administration had freshness during that period. United medical administrative system was generally formed, chicken pox was effectively prevented, shamanistic treatment was banned, medical journals were complied by the government, medical relief was more intensely done. However, actions on restoring Ming dynasty and against Qing dynasty as well as the reform power grew against Qing government threatening it. The drastically grown forces from the western region damaged Qing dynasty that the governors had to adopt despotic measures in politics, economy and culture. Social chaos began to arise, economy stagnated and weakened that the medical field also dwindled to the point where it could not be restored to the original point. The era of Qing dynasty was the period that had scientific culture at its fast growing pace, but for Chinese medicine, by contrary, due to autocracy and other factors, was faced with barriers in the medical development.

  • Genetic algorithms have been successfully applied to various optimization problems belonging to NP-hard problems. The sequential ordering problems(SOP) and the job shop scheduling problems(JSP) are well-known NP-hard problems with strong influence on industrial applications. Both problems share some common properties in that they have some imposed precedence constraints. When genetic algorithms are applied to this kind of problems, it is desirable for genetic operators to be designed to produce chromosomes satisfying the imposed precedence constraints. Several genetic operators applicable to such problems have been proposed. We call such genetic operators precedence-preserving genetic operators. This paper presents three existing precedence-preserving genetic operators: Precedence -Preserving Crossover(PPX), Precedence-preserving Order-based Crossover (POX), and Maximum Partial Order! Arbitrary Insertion (MPO/AI). In addition, it proposes two new operators named Precedence-Preserving Edge Recombination (PPER) and Multiple Selection Precedence-preserving Order-based Crossover (MSPOX) applicable to such problems. It compares the performance of these genetic operators for SOP and JSP in the perspective of their solution quality and execution time.

  • Purpose: To investigate the health problems and health services in child day care centers. Methods: Data were collected from 115 teachers at 16 child day care centers in Seoul city. A questionnaire was used to collect data, which were analyzed with the SPSS 12.0 program. Results: Most teachers had experienced various child health problems such as colds, hand․foot․mouth diseases, chicken pox, skin injuries, nasal bleeding, vomiting and diarrhea. Furthermore, they even experienced some serious ones including dysentery, measles, asthma and seizures, which demand professional skill. However, there were no registered nurses and most teachers requested that parents take a child home when these health problems happened. Only 31.3% of the child care centers had a teacher with CPR training. Approximately half of the centers kept child health records which included reports on allergic substances, and medical history but only 18.7% of the child care centers offered regular immunizations for the children. Conclusion: Various health problems were found in child day care centers. To maintain the children's health, there is a need to develop and make provisions for health services and programs in child day care centers.

  • Nephrotic syndrome (NS) is one of the most common glomerular diseases that affect children. Renal histology reveals the presence of minimal change nephrotic syndrome (MCNS) in more than 80% of these patients. Most patients with MCNS have favorable outcomes without complications. However, a few of these children have lesions of focal segmental glomerulosclerosis, suffer from severe and prolonged proteinuria, and are at high risk for complications. Complications of NS are divided into two categories: disease-associated and drug-related complications. Disease-associated complications include infections (e.g., peritonitis, sepsis, cellulitis, and chicken pox), thromboembolism (e.g., venous thromboembolism and pulmonary embolism), hypovolemic crisis (e.g., abdominal pain, tachycardia, and hypotension), cardiovascular problems (e.g., hyperlipidemia), acute renal failure, anemia, and others (e.g., hypothyroidism, hypocalcemia, bone disease, and intussusception). The main pathomechanism of disease-associated complications originates from the large loss of plasma proteins in the urine of nephrotic children. The majority of children with MCNS who respond to treatment with corticosteroids or cytotoxic agents have smaller and milder complications than those with steroid-resistant NS. Corticosteroids, alkylating agents, cyclosporin A, and mycophenolate mofetil have often been used to treat NS, and these drugs have treatment-related complications. Early detection and appropriate treatment of these complications will improve outcomes for patients with NS.
