  • As the government strengthens its policy of separating and discharging packaging materials, consumers are increasingly dissatisfied. In order to increase consumer participation in separate discharge policy of packaging materials, it is necessary to increase the willingness to participate by reducing potential consumer problems such as removal of packaging labels. This study conducted a survey of 300 consumers aged 14 and over who recycle and discharge directly from their homes. Ninety-nine percent of consumers said PET bottles are released separately. However, only 65% of consumers removed labels (attachment labels, shrink labels) and other materials (caps, vinyl coatings, tapes, handles, bases, etc.) during separate discharge process. Nearly 52% of consumers cited 'difficulty of separation' as the main reason for not removing labels and other materials. One-way ANOVA analysis showed that 'strong adhesion', 'removal initiation problem' and 'material strength' had high mean regardless of age, which are major factors impedes label removal. Using shrink labels with perforated lines rather than adhesive labels would be more beneficial to encouraging participation in separate discharge. However, if the shrink labels do not have perforated lines or are difficult to remove, adhesive labels are often easier to remove than shrink labels because of the strong cohesiveness of shrink labels. As a result, how easy it is for consumers to remove the label is more important than technological differences. In order to increase consumer participation in packaging material and label separations, improvements in structural design are needed along with the selection of materials that are easy to separate. This study is meaningful in examining consumer perceptions, deriving problems and suggesting directions for policy improvement.

  • To lead rural clothing management in the rural household, we assessed in terms of the wearing of pesticide protective clothing and care methods of contaminated clothing, consumer consciousness, the discard method of clothing et al. in rural areas of Gyonggi-Do by sampling 122 households. The results are as following ; 1. The behavior for laundering management didn't appropriate in view of certification of label about laundry method, frequency of laundry and quantitative use of detergent. Also family's cooperative attitude wasn't insufficient. 2. Reasons of dissatisfaction about retained clothing were decreased in order of discoloration, shrink or breakage after laundry, breakage of seam or cloth, unlabel, allergy from cloth. The solution of trouble was acted passively. 3. Reasons of hoarding of clothing were high because of change on size, fashion, and low because of wornout. Still-wearable garments were discarded in proportion of one to one. 4. The ratio of putting on the fatigue cap which the Once of Rural Development has propagated was under 10 percent. 5. Protective clothes against agricultural chemicals had not been prepared and contaminated clothing was often washed with regular family wash.

  • Data on the Internet are usually represented and transfered as XML. the XML data is represented as a tree and therefore, object repositories are well-suited to store and query them due to their modeling power. XML queries are represented as regular path expressions and evaluated by traversing each object of the tree in object repositories. Several indexes are proposed to fast evaluate regular path expressions. However, in some cases they may not cover all possible paths because they require a great amount of disk space. In order to efficiently evaluate the queries in such cases, we propose an optimized traversing which combines the signature method and block traversing. The signature approach shrink the search space by using the signature information attached to each object, which hints the existence of a certain label in the sub-tree. The block traversing reduces disk I/O by early evaluating the reachable objects in a page. We conducted diverse experiments to show that the hybrid approach achieves a better performance than the other naive ones.
