Three catalase cDNA clones were isolated from the small radish (Raphanus sativus L.). Their nucleotide and deduced amino acid sequences showed the greatest homology to those of Arabidopsis. Genomic Southern blot analysis, using RsCat1 cDNA as a probe, showed that catalases are encoded by small multigene family in the small radish. Nondenaturing polyacrylamide gels revealed the presence of several catalase isozymes, the levels of which varied among the organs examined. The isozyme activities were assigned the individual catalase genes by Northern analysis using total RNA from different organs. The three catalase genes were differentially expressed in response to treatments such as white light, xenobiotics, osmoticum, and UV. Their expression in seedlings was controlled by the circadian clock under a light/dark cycle and/or in constant light. Interestingly, RsCat1 transcripts peaked in the morning, while those of RsCat2 and RsCat3 peaked in the early evening. Our results suggest that the RsCat enzymes are involved in defense against the oxidative stress induced by environmental changes.

들깨 '수원25호', 담배 'L8', 'KF109'와 'NC82', 시금치 '입추'와 나팔꽃을 생장혼경조절이 가능한 대기오염원 노출상에서 SO? 140ppb/시간 또는 O? 150ppb/시간의 농도로 하루 24시간 10일 동안 노출시킨 결과 '수원25호' 들깨와 담배 'L8'은 SO?에 민감한 반면, 담배 'L8'과 나팔꽃은 오존에 아주 민감한 것으로 판명되었다. 위의 농도에서 가시적 피해가 조사식물의 50%에서 발생하는 병반발생빈도 50%(SF?)를 기준으로 설정한 한계노출시간 조사에서 오존에 대한 한계 노출시간은 담배 'L8'의 경우 24시간, 나팔꽃의 경우 72시간, 담배 'NC82'와 'KF109'의 경우 144시간 내외, 시금치의 경우 216시간으로 추정되었으며, SO?에 대한 한계노출시간은 담배 'L8'의 240시간을 제외하고는 모든 식물에서 240시간 이상으로 추정되었다.

The application of fertilizer P to Desmodium intortum at 40, 60 and 100 kg/ha resulted in the P content of the legume regrowth being 0.10, 0.13 and 0.16% on a dry matter basis. When the forages were fed alone to sheep in metabolism pens the corresponding voluntary intakes by sheep of the three forages were 27.3, 42.7 and $54.3g/W_{kg}{^{0.75}}$, respectively. Provision of additional P by rapid infusion into the rumen each morning before any fresh food was offered depressed the voluntary intake of all three feeds. It is suggested that the adverse effect of supplementary P was probably caused by an induced deficiency of either Ca or Mg and led to a reduction in microbial activity in the rumen.

Tree-harvesting worker data of 508 separate worker accidents are analyzed and an exploratory approach taken. The worker accident data cover a sample of five years. The scope of the study was the southeastern United States of America. As might be hypothesized, the chainsaw was the most hazardous type of tree-harvesting equipment. It accounted for 55％ of the tree-harvesting accidents. Most chainsaw accidents resulted in injuries to the lower extremities and were more frequent among younger employees. The probability of one or more chainsaw accidents occurring in any 30-day period was approximately 0.856. Chainsaw accidents were more likely to occur in late morning and early afternoon. We used statistical tools such as Pareto charts, c-charts and Ishikawa diagrams. Such tools are useful in diagnosing the root-cause of tree-harvesting worker accidents and help in developing preventive safety programs. Recommendations to help improve the quality of information of accident data collected by insurance companies and others are briefly given. The strategy and culture of continuous process improvements are stressed.

This study describes experimental study on the performance characteristics with load condition in hybrid solar heating system during spring season. The room temperatures, the hot water conditions and the lower part temperatures of heat storage tank were changed to analyze the system performances. As a results, the hot water was significantly affected by the ambient temperature. The indoor setting temperature affected the solar fraction. When the low part temperature of the storage tank increased, the temperature of the hot water rose and the temperature of the hot water in morning was affected by the ambient temperature.

Antibiotics susceptibilities of Staphylococci were tested to get useful data for prevention food contamination and treatment of food poisoning. Tested were colony counts, isolation of Staphylococci, identification for the Staphylococcus aureus and resistant patterns to antimcrobial agents. The colonies and Staphylococci isolated from the atmosphere of 37 home kitchens in the morning (07:00-08:00) on Nov. 19, 1977 in Busan. The findings are as follows: 1. The average of colony counts was shown to be 9.6 ranging from 47 to 1 at mean temperature of 18$\circ$C (the highest 21$\circ$C, the lowest 15$\circ$C) 2. Out of total 37 kitchens, 18 Staphylococci were isolated from 15 kitchens with 40.5 per cent, and 4 Staphylococcus aureus were identified with 22.2 per cent from 18 Staphylococci. 3. Isolated Staphylococci were resistant to penicillin(100%), dihydrostreptomycin(93.3%), tetracycline (93.3%) and oleandomycin(66.6%), while the strains were sensitive to sulfonamide(88.6%) and colistin(83.3%). 4. Staphylococcus aureus identified were resistant to dihydrostreptomycin, penicillin and tetracycline, while the strains were sensitive to sulfonamide and colistin.

Interviews of 208 women concerning dietary changes during pregnancy were under-rtaken from September 1986 to January 1987 at the medical centers in Seoul and Kyung Ki. 84% of the total subjects felt the morning sicksnes such as nausea and vomiting within the first trimester of pregnancy. There was a significant correlation between the experience of moring sickness and some environmental factors such as school carreer, food intake in early pregnancy, the number of meals and taking of medicines for promoting nutrition. Foods for which specifie cravings were frequently cited were fruits, meats, cold noodle, noodle and chinese food. Foods of aversions were Kimchi, meats, fish and fatted foods. With regard to beverage, there were the increase in milk and fruint juices consumption and the decrease in coffee ingestion during early pregnancy primarily attributed the concern for feto-maternal health. Possible explanation for these changes associated with pregnancy discussed.

Central anticholinergic syndrome occurs when an anticholinergic substance works in vivo or as a result of the insufficient release of acetylcholine. Its symptoms include confusion, agitation, behavioral change, hallucination, blurred vision, and dysarthria. Occasionally, these symptoms occur with the use of a scopolamine patch. A 54-year-old female complained of behavioral change and confused mentality. She attached a scopolamine patch at the postauricular area in the morning of the day before her hospital visit. Neurological examination revealed bilateral symmetric mydriasis without light reflex. The brain MRI was normal, and electroencephalography showed nonspecific abnormalities. The patient recovered completely after the removal of the scopolamine patch.

Diel vertical distribution of phytoflagellates and interactions between the phytoplankton components and environmental and biological factors were studied in a small artificial pond for three days on the December 18, 1998 and April 9 to 10, 1999. The phytoplankton population was dominated by Mallomonas akrokomos of chrysophytes and Cryptomonas marssonii and Chroomonas sp. of cryptophytes. The vertical distribution of these phytoflagellates taxa exhibited clear diel migration pattern. Moreover their migration patterns are showed differential fluctuation between M. akrokomos, C. marssonii and Chroomonas sp. The later two species upward migrated in the evening as well as night, whereas the former species migrated downward. Their distinctive migration pattern was found during the night but was not observed in the morning. During daytime C. marssonii and Chroomonas sp. showed maximum density above 2 m depth but M. akrokomos below 2 m depth. The diel vertical distribution of the dominant phytoflagellates did not show significant correlation between physical, chemical and biotic factors.

A study to assess the physiological stress responses in goats that were subjected to road transportation was carried out using 10 Kacang crossbred does. Five does were transported in the morning with another five transported in the afternoon covering a distance of 46 km in an open-truck at an average speed of 55 km/h. Immediately following the road transportation, there were dramatic increases in neutrophil:lymphocyte ratios and plasma glucose concentrations but plasma cholesterol concentrations and body temperature were not affected. The neutrophil:lymphocyte ratios and plasma glucose concentrations appear to be reliable indicators of stress in goats.
