Neutral or alkaline papermaking provides many advantages in paper strength and processing conditions. It also provides the opportunity of using calcium carbonate fillers in papermaking. These diverse advantages have made almost all paper machines of printing and writing papers run under neutral and alkaline conditions. On the other hand, linerboard machines, which use recycled papers as a raw material, are running under acid conditions using a rosin sizing system. Because the recycled raw materials used by the linerboard industry contain significant amounts of alkaline papers, the linerboard industry has an interest in the possibility of using the neutral or alkaline papermaking opportunity. In this study, the compatibility of the recycled linerboards under neutral or alkaline papermaking conditions was examined by recycling them under various pH conditions. The sizing degree of the papers recycled under neutral or alkaline was significantly lower than that of acid formed papers indicating that during the neutral or alkaline recycling process the rosin sized papers lost their sizing efficiency. Recycling of acid formed linerboards under neutral or alkaline conditions increased the amount of foam, and the foam contained substantial amount of solid materials derived from the acid sizing systems. Use of cationic polyelectrolytes including PEI and poly-DADMAC improved the sizing degree of the recycled papers under neutral and alkaline conditions. PEI decreased the foam generation as well while poly-DADMAC did not show any reducing effect of the foam. These results suggest that PEI forms coordinate bonds with rosin acid and precipitate them onto the surface of recycled fibers, while the reaction products between poly-DADMAC and rosin acid ions still remain water soluble under neutral or alkaline conditions.

The results of analyzing the 20 piece of surface sediments were characteristics following Textural and geochemical, aspect. The mean size is 0.20-6.22 rP, but the sorting 0.5-3.96, however, The Skewness is -0.28 - 5.7, and Kurotosis shows a range of 1.70 - 20.30. The geochemical characteritics were showed relationship with mean value in all elements in the fine grained sediments and K20 in coarse graned sediments, The minor element Cd, Cu, Pb, Zn, Cr, Li in fine grained sediment, Ba in coarse grain sediment. The Hg element is demonstrated in the all section of distribution. The high possibility of pollution element Pb, Zn which mean concentration is appeared highly at the adjacent in land sea area. It give a preview that this area being polluted.

I. The supply of protein, carbon hydrate, fat in the material of food were plentiful for surplus the 2 -3.9 times on the level of food stuff, but vitamim 82, C, were rack of the required standards of food stuff. II. The calories of supplied food was 3,060.61 Kcal in the early stage of voyage, 3,142 Kcal in the middle stage the voyage, 3,021 Kcal in the last stage of voyage mean 3,074.64 Kcal similarly. III. As to the calories of intake. The crew(3,266.4 Kcal) was higher than the cadet(2,829.8 Kcal). The calories of intake was small to the end stage of voyage to the cadet. IV. The difference of the calories of consumtion and intake was 2.10% in the case of crew, 4.25% in the case of cadet, mean 3.175 % similarly. V. The supply of freshwater was plentiful and the variation of body weight is no account for the crew but the cadet is decreased 1.2kg a man at the last disembarkation day. VI. The 3rd rule for food stuff supply as to the 74th rules seamans Act were desireable to amend according to the nutrition level of nutrtion recommended amount.

The parcel wrapper for cigarettes has been used as the package and media materials for protection and design of product brands. The design of parcel wrapper has been contributed to the delivery of brand image and motivated consumer to purchase the brand. Therefore, the properties of parcel wrapper have been paid attention to highlight the design image, and increasing opacity of media materials has been one of the effective ways to obtain clear design on the paper surface. This study was carried out to improve the opacity of parcel wrapper for cigarettes. The effects of pulp composition and inorganic fillers in the furnish on the optical and mechanical properties were investigated. The use of hardwood in the stock preparation gave the increased opacity of paper than that of softwood. The application of higher refractive indices of fillers was effective to improve opacity. Brightness, tensile strength and stiffness were affected by the retained filler amount on the paper. Increase of filler contents decrease the tensile strength and stiffness due to the lesser bonding ability of fibers.
