Cylindrical dry forming mould was developed to carry out a feasibility study of dry forming of papers. The effect of disintegration, forming, humidification and pressing on dry formed papers was examined. Dry disintegrated fibers showed the similar fiber length distribution to wet disintegrated fibers, but they showed distorsion and damaged appearance on the surface. Process parameters required to form a uniform fiber pad was investigated. A proper screening and air dispersion method was selected that gives proper formation. Humidification and pressing conditions were examined to get a good dry formed papers in dry forming. Results showed that dry forming method can be used to make a sheets with reasonable formation and properties.

Behavior of micro stickies was analyzed using model micro stickies prepared with PVAc emulsion adhesive. Flocculation of micro stickies increased with temperature. Acidic state also induced greater flocculation of micro stickies since they became more unstable under these conditions. Flocculation of micro stickies increased as calcium ion concentration increased. But the presence of calcium carbonates made micro stickies dispersed indicating that calcium carbonates cause two different effects on the behavior of micro stickies. Talc increased flocculation of micro stickies because of its hydrophobic nature. Cationic polymer increased flocculation of micro stickies. Especially cationic starch has far greater effect in flocculating sticky particles by forming bridging flocculations.

The purpose of this study was to provide the basic informations of disposable medical clothes and develop new disposable medical clothes which are not caused environmental pollutions. The staffs of Yuhan-Kimberly and doctors, nurses and personnel of four general hospitals in Seoul were interviewed individually in order to collect useful data of disposable clothes. Also the samples of disposable medical clothes were examined. The materials, designs, size of potential market and actual consumption conditions of disposable medical clothes were found out. New disposable medical clothes were made after having considered all the aspects examined above. Two kind of medical gowns and caps, a kind of medical apron, three kinds of patient robes and a kind of patient cap were made of Korean traditional paper with specific functions instead of nonwoven polypropylene fabric.

Purpose: The purpose of this study was to identify stress and coping patterns of manufacturing male workers. Method: Data were collected from 215 manufacturing male workers and analyzed by SPSS WIN 12.0 Results: The total job stress score was 41.41 and the mean of the daily hassles score was 1.60. Related to the coping type, direct-active coping was the highest among four types of coping. Indirect-active coping was the second, followed by direct-passive coping and indirect-passive coping. Job stress score and daily hassles score were highly correlated by passive coping types. Conclusion: Occupational health management program including coping strategy is required to relieve workers' stress.

기업의 사회적 책임 인식이 미약한 편인 우리나라의 경우 사회공헌활동도 대부분 구호차원에서 전개되어 왔다고 하여도 과언이 아니며, 대부분의 활동도 일부 대기업을 중심으로 이루어져 왔다. 한편 최근 몇몇 기업들이 공익과 기업의 성공이라는 두 목적을 성취하려는 공익연계마케팅(cause-related marketing)에 대하여 증진된 관심을 보이고 있는 가운데 우리가 참고할 만한 사례로는 어떠한 것이 있을까 ? 우리나라 공익연계마케팅의 시작이라고 볼 수 있는 사례는 유한킴벌리가 1984년부터 시작하여 지금까지 진행하여 온 '우리강산 푸르게 푸르게' 캠페인이다. 물론 많은 어려움과 위험을 내포하고 있겠지만, 우리나라의 공익연계마케팅활동이 더욱 확산·활성화되기를 희망하는 것이 본 사례연구의 거시적 취지이다. 구체적으로 본 사례는 유한킴벌리의 공익연계마케팅활동의 내용을 상세히 살펴본 후 관리적 차원에서 그 내용을 분석하였다. 또한 공익연계마케팅활동의 바람직한 방향과 시사점, 그리고 더 생각해 보아야 할 과제들에 관하여 논의하였다.

This study's goal is to analyze the color characteristics of Blue used in men's fashion for design developing process. First, we researched the previous studies and examined documents about color characteristics of Blue in general as well as coloration in fashion design and men's fashion. We composed color samples by collecting two-color coloration used in men's fashion collection for 5 years from 2004 S/S to 2008 F/W through a specialized fashion information web-sites. We limited the colors from Blue Green(BG) to Purple Blue(PB). Second, we analyzed the characteristics of hue combination and tone combination. A total of 351 pictures were collected and RGB and HV/C value were converted with Munsell Conversion program(ver.8.0.1). Color data has been sorted to 10 hues and 12 PCCS tones. From this, we were able to figure out that similar/same hue coloration was used more than contrary hue coloration and similar/same tone coloration was used more than contrary tone coloration for Blue. We've limited Blue coloration characteristics of men's fashion to two-color coloration for an analysis; the succeeding study will need to examine on the characteristics of multi-coloration and detailed Blue coloration image by various garments.

This study was conducted to develop dry forming technology and evaluate the properties of dry formed paper made from Hw-BKP. A dry forming mold (DFM) was developed to observe the phenomena of dry forming and evaluate the properties of formed papers. To upgrade the DFM a dry forming system (DFS) was developed. This DFS was designed to improve the formation of dry formed papers and enhance the productivity of dry forming. Dry forming gave papers with greater bulk and opacity than wet forming. Tensile strength of dry formed paper was greater than that of conventional wet formed handsheet when they were made from the same dry disintegrated fibers. But tensile strength of conventional wet formed handsheet made from beaten fiber was much greater than that of dry formed paper made from dry disintegrated fibers. When solvent dried beaten fibers were used in dry forming, the tensile strength of dry formed papers reached 73.5% of the wet formed handsheets made from beaten fiber. It showed that dry forming has a significant potential in improving strength properties when proper preparation of fibers and appropriate humidification, pressing, and drying processes are employed.

Disposable diaper waste is consisted of plastic, fiber, and SAP (Super Absorbent Polymer). They are valuable to be used as raw materials of other products including plastic blocks and pulp mold. Nevertheless, disposable diaper waste have been disposed by landfill and incineration without recycling. Due to strict environmental regulations it is necessary to develop fractionation technique to recycle the disposable diaper waste. In this study the fractionation technique using pilot-scale stock preparation units was investigated. Process for separation of plastic and fibers from disposable diaper waste was composed by the combination of pilot-scale pulper, drum screen, screen and cleaner. Recovery rate of plastics and fiber was checked according to the various operating conditions. In drum screen, recovery rate of plastic was high when the cut size of disposable diaper waste was $5cm{\times}5cm$. The highest recovery rate of fiber was achieved with 0.3 mm slot screen. It is important to control the neutral state of SAP for improvement of recovery rate of fiber since SAP can be swelled easily in water. Therefore SAP can be controlled efficiently by the addition of calcium chloride into the pulper. Consequently recovery rates of plastics and fibers were over 90 and 80% under the optimum pilot operating conditions.

The purpose of this study is to examine the reusability of the fluff pulp recycled from paper diaper. To do this, the physical and optical properties of each handsheet made from these fluff pulp sample as well as the properties of the fiber recycled from paper diaper were analyzed and compared with those of non-recycled diaper fluff pulp samples and conventional pulp samples. These comparisons show that the characteristics of fiber such as length, width, curl, kink of the pulp recycled from paper diaper were similar to those of non-recycled diaper fluff pulp as well as to those of commercial pulp. The fine content of recycled diaper fluff pulp was lower than that of other pulp samples, while the ash content of the former was higher than that of the latter. Furthermore, it was also found that the bulk of handsheets made from the recycled fluff pulp was higher than that of other pulp samples, while the formation of the former was worse than that of the latter. The mechanical properties of the handsheet sample made from the recycled diaper fluff pulp was higher than those of the unused diaper fluff pulp and was lower that those of commercial fluff pulp and softwood tissue pulp handsheet. But, it was higher than that of hardwood tissue pulp handsheet. The optical properties of recycled diaper fluff pulp handsheet was lower than those of each handsheet samples made from other pulps due to its low fine content.
