  • Biosynthsis of prostaglandin E2 (PGE2), the most common prostanoid with potent and diverse bio-activities, is regulated by three sequential enzymatic steps composed of phospholipase A2, cyclooxygenase (COX), and prostaglandin E synthase (PGES). Recently, three distinct PGESs have been identified; two of them are membrane-bound enzymes, mPGES-1 and mPGES-2, and the third one is a cytosolic enzyme, cPGES. (omitted)

  • Several aspects about the epidemiological status of chicken coccidiosis, its control measures and recent research activities in Korea are discussed in this paper. Medication with different available anticoccidial drugs has been reasonably effective in treating and preventing serious outbreaks of coccidiosis in chicken, but the disease remains one of the most expensive and common diseases of popultry production in this country, and more recently its incidence is increasing, possibly due to the more intensive methods of husbandry and the immergence of resistant strains of coccidia. Therefore, this necessitates a continuous search for new methods such as medication program (shuttl and rotation program) and immunization using attenuated strains or parasite antigens.

  • The Assessment using the observation is one of the common ways to know what the student knows and dose not. Using the obserbational Assessment, Teachers, analyzing student's growth, provide appropriate feed-back, and so they try to record every activities. but, accumulatively recording the result of observational assessment face time·spacial limits. and it is difficult to apply in a real classroom situation. Taking these into consideration, I'd like to take a look at the idea of check-list assessment that could record data observing student and contrive a practical ways of application.

  • Polyketides are a class of structurally diverse natural products which possess a wide range of biological activities. These compounds are used throughout medicine and agriculture as antimicrobials, immunosuppressants, antiparasitics, and anticancer agents. While structurally diverse, polyketides are assembled by a common mechanism of decarboxylative condensations of simple malonate derivatives by polyketide synthases (PKSs) in a manner very similar to fatty acid biosynthesis (Fig 1).

  • Depression is common psychiatric diseases characterized by diverse physical and emotional symptoms including low mood, loss of interest in pleasurable activities, and feelings of worthlessness. Depression causes of death and disability. The first antidepressant was created by the idea that central serotonin mechanism. Selective serotonin reuptake inhibitor, fluoxetine is the first-line drug in the treatment of depressive disorder and their few side effects as opposed to tricyclic antidepressants. Not all people with depression respond adequately to standard treatments. Korean music playing/listening actions appear to be a reliable approach to developing recovery from depression.

  • The purpose of this study was to assess the performance of the role and function of some industrial nurses and to characterize the factors affecting the performance of their activities. Thus the results could be used to suggest the direction in the performance of industrials nurses' activities effectively. During a period from January 10 to March 31, 1994, the data were collected from 87 industrial nurses, who were working as health managers in the plants, in Ulsan city and the vicinity in Kyungnam province, using a structured questionnaire. The results were as follows : 1. The general characteristics of industrial nurses in this study were 82.8% being 30 years old or less, 60.9%, being not married, and 93.1% having eduction levels above junior college. 2. With respect to general work conditions, 94.3% were working in a separate room provided for health care division, 40.2% working under the safety and health department, and 98.9% working as common-level staffs. And 60.9% were working less than 44 hours a week, 70.1% had work experiences less than 5 years, and 50.6% had annual incomes ranging 10 to 14 million wons. 3. As work conditions related to health care activities, 49.4% performed the activities not related to health care as always or occasionally, and 87.4% answered that occupational physicians were appointed in their plant and among them, however, only 6.9% worked on full-time basis and 52.8% perform little activities as occupational physicians. For a decision related to health care activity, 69.0% discussed the problems with the supervisors, and 19.5% made decisions by themselves. 4. As for attitude and perception to their activities as health managers, 66.7% moderately recognized the importance of health manager in the workplace, with 63.2% being satisfied their wages and treatment from the company, 57.5% being satisfied with their job positions and 51.7% having positive attitudes as being health managers. 5. The degree of performance at least in one of health related activities were very high in activities such as general medical care(100%), general health examination(98.0%) and specific health examination(100%), and relatively high in health education(72%), new employee health examination(60.9%), document handling(79.3%) and activity for work environment(70.1%). However, the performance rate was very low in preparing protective equipment (20.8%). 6. The levels of activities related to health care were significantly high when making decisions by themselves, when occupational physicians not being full-time, and when satisfying their job positions, and, on the other hand, significantly decreased as work hours increased. 7. In addition to some kinds of periodic education asked by all of the nurses, 89.7% wanted a specialized licensing system for industrial nurse, and 97.4% wanted to apply for the license test. As a conclusion, it is suggested that industrial nurses should be given more authority and placed in more self-controlled system to perform health care and other activities more efficiently, and the role and function of the occupational physician should be clearly distinguished from that of the industrial nurse as a health manager to avoid an unnecessary overlapping.

  • The changes of growth characteristics and antioxidant activity for selection of optimum germinated temperature on common bean (Phaseolus vulgaris L.). Common beans (IT100888, IT102849, and IT231267) were cultivated at $20^{\circ}C$, $23^{\circ}C$ and $25^{\circ}C$ during 5 days of germination. The range of whole length, hypocotyls length, thickness, abnormal germination and yield rate of sprouts was 7.27~27.62 cm, 3.10~18.86 cm, 1.80~2.27 mm, 5.54~18.34% and 205.95~ 618.71%, respectively. Antioxidant activities of common beans with germination temperature investigated. Common beans (IT100888, IT102849, and IT231267) germinated at $20^{\circ}C$, $23^{\circ}C$ and $25^{\circ}C$ during 5 days, and then extracted with 80% ethanol, and analyzed for total polyphenol content, DPPH and ABTS radical scavenging activity. Total polyphenol content increased from 474 mg GA eq/100 g sample for IT231267 to 1364 mg GA eq/g sample for $23^{\circ}C$ of germination. DPPH radical scavenging activity of IT102849 increased from 189mg Trolox eq./100 g sample ($20^{\circ}C$) to 1073mg Trolox eq./100 g sample ($23^{\circ}C$) also ABTS radical scavenging activity of IT234267 increased from 479 mg Trolox eq./100 g sample ($20^{\circ}C$) to 1134 mg AA eq/100 g ($23^{\circ}C$). These results suggest that germination temperature for increasing antioxidant activities may be $23^{\circ}C$.
