  • The moving behaviour of anchovy schools(There were small schools of sardine and round-herring in this anchovy schools} in the bag - net of a large scale set - net was investigated using a scanning sonar, in the Kishihata set - net fishing ground located in Nanao city Ishigawa prefecture, Japan from Dec. 1st to Dec. 4th, 1992. The results obtained are summarized as follows ; 1. Moving behaviour of fish schools between two bag - nets was more in the daytime than in the nighttime. 2. The rate of entering fish schools from the first bag -- net to the second bag - net were 78% when the fish school in the second bag -- net existed. The result suggest that fish school existence in the second bag - net affected the rate of entering fish schools from the first bag - net to the second- bag - net. However, the time of stay of fish school that entered the second bag -- net was very short when the fish school in the second bag - net existed densely. The result suggest that a high fish density in the second bag - net might enlarge the escape rate 3. The majority of fish schools moved to the center and off shore side of the bag - net when fish schools entered the bag - net.

  • This study was carried out to examine the nutritive values and quality of agricultural bag (AG-BAG) silage manufactured with corn grown in reclaimed paddy field of Sukmoon at Dangjin Province in Korea. The cultivars of silage corn used in this experiment 1 were both Kwangpyungok and P32B33. The fertilizer were applied with the amounts of customary applications (200 kg N/ha, 150 kg $P_2O_5$/ha and 150 kg $K_2O$/ha). The content of moisture in corn AG-BAG silage ranged from 68 to 79%. The pH in corn AG-BAG silage stages ranged from 3.49 to 3.65 and was not influenced by the harvest time. The contents of crude protein (CP) in corn AG-BAG silage decreased with delayed harvest time. However, the contents of ADF (acid detergent fiber) and NDF (neutral detergent fiber) increased. The content of lactic acid increased with delayed harvest time, but the content of acetic acid decreased. Therefore, we suggest that the system of AG-BAG silage can improve the quality of corn silage and be one of the economical and effective methods to manufacture corn silage.

  • Perineal discomfort from episiotomy continues to be a problem for many postpartum women. The purposes of this study were to compare the effect of ice bag and heat lamp for the relief of perineal discomfort and to identify the sustaining time of each effect. Forty women took ice bag and heat lamp with random assignment of initial therapy. Women rated the degree of perineal discomfort before and after each therapy and at half-hour, tow-hour and four-hour intervals after each therapy. A discomfort scale, 18cm graphic rating scale, was used. The results of the study were as follows ; 1. The ice bag group showed significantly lower discomfort score than the heat lamp group at the half- hour and two - hour intervals after therapy. 2. The ice bag group showed significantly lower discomfort score for 4hrs after than before therapy, but the heat lamp group did not show significantly lower discomfort score. 3. Neither the type of episiotomy nor the previous experience of heat therapy influenced on the effect of ice bag relieving the perineal discomfort. Therefore ice bag was significantly mere effective in relieving perineal discomfort than heat lamp. Subjective responeses of patients who took both therapy were very favorable toward ice bag. I suggested that nurses should provide women with adequate information about the use of ice bag and encourage to apply ice bag instead of heat lamp after episiotomy in order to promote the relief of perineal discomfort and the healing of perineal wound.

  • The high temperature pleated filter bags which were used during this study were made of pleated nonwoven fabric of heat and acid resistant polysulfonate fibers which can withstand the heat up to $300^{\circ}C$ and have a filtration area which is 3 to 5 times larger than the conventional round filter bags. Cartridge module packed with 3 kind of the sulfur impregnated activated-carbon based sorbents were inserted in the inner of the pleated filter bag. This type of pleated filter bag was designed to remove not only the particulate matter but also the gaseous elemental mercury. The electrostatic precipitator part can enhance the particulate removal efficiency and reduce the pressure drop of the pleated filter bag by agglomerated particles to form a more porous dust layer on the surface of the pleated bag which is increased the filter bag cleaning efficiency. In addition, the most of particles are separated from the flue gas stream through the cyclone and the electrostatic precipitator part which were installed at the lower part and main body part of the convergence particulate collector, respectively. Thus reduce particulate loading of the high temperature pleated filter bags were applied in this study to analyze the removal characteristics of particulate matter and gaseous elemental mercury.

  • The mineral contents, and free amino acid, and fatty acid composition of rack and bag or suspended cultured oysters Crassostrea gigas were compared. The moisture content did not change much from 82.8% to 86.3% in the different culture methods. The glycogen level was low 4.7% during rack and bag culture but high 7.2% during suspended culture. The sodium level was the highest during suspended culture, while copper and zinc level were highest during rack and bag culture. The taurine level was 1,385-1,375 mg/100 g in oyster cultured using the rack and bag method, but that in the market sample was lowest at 1,015.8 mg/100 g. Hydroxyproline, glutamic acid, proline, glycine, and alanine were detected at high levels in the experimental oysters. The polyunsaturated fatty acid content was similar among samples. The docosahexaenoic acid level was 14% with rack and bag culture and 12% with suspended culture, whereas the eicosapentaenoic acid level was 15% with rack and bag culture and 20% with suspended culture. The atherogenic index (AI), thrombogenicity index (TI), and hypocholesterolemic/ hypercholesterolemic (h/H) ratio were important factors in the nutritional evaluation. The AI and TI values were 0.5-0.2, and the h/H ratio were 2.0 and 2.4 with the rack and bag and suspended culture, respectively.

  • In an attempt to select grape bag, which elevates grape quality and make easy maturation period determination, the following research was carried out at Chungbuk Institute of Agricultural Technology, Grape Experiment Station. Light transmittance rate of bag reached to 11-65% with non-woven fabric and non-dripped vinyl bags. Non-dripped vinyl perforation and white painting bag resulted in 50 and 75%, respectively. Berry weights in non-woven fabric and non-dripped vinyl bag were high than that in paper bag. Non-dripped vinyl perforation 50%, white painting bag brought into fruit cracking, shattering, and rotten fruit, making the investigation difficult. Maturation period preceded about 1-4 day with non-woven fabric and non-dripped vinyl compared with that in paper bag. Soluble solids content with non-woven fabric and non-dripped vinyl bags was high and acidity showed a reverse result. Coloring extent was developed rapidly with non-woven fabric and non-dripped vinyl than paper bag. During initial state of coloring, coloring was rapid with Maekban-Stone mixed non-woven fabric and non-dripped vinyl + non-woven fabric bag. This was rapid with non-woven fabric bag as long appropriate maturation period. Abnormal berry rate was 5.4-7.0% with paper and non-woven fabric bags but brought about as much as 16.6-100% with non-dripped vinyl and it's mixed bags. Appearance quality was the best with index 9.0 for non-woven fabric bag. Maekban-Stone mixed non-woven fabric but non-dripped vinyl performance 50% white painting bag was the least, showing index 1.0. The time consumed for maturation determination was reduced to 74-93% with non-woven fabric and non-dripped vinyl bag compared with 17.4h/10a with paper bag.
