Marine microalgae have different collection methods depending on their habitat. In the case of adhesive microalgae, it is difficult to separate organisms from the substrate surface, and contamination is likely to occur during the sampling process. In this study, we analyzed the collection efficiency of adhesive microalgae using three artificial fiber materials (nylon, blend fabric, and viscose rayon). Each fiber showed different fiber diameter and pore characteristics (nylon 26.09 ㎛, blend fabric 56.6 ㎛, viscose rayon 101.3 ㎛). In addition, attached organisms were collected on the surface of artificial substrates at Bukseong Port in Incheon using each tested fiber material. After that, we investigated the population and species composition. The highest number of cells was found in nylon, which was 8 times higher than in the least collected viscose rayon material. In addition, we identified 24 microalgal species from the substrate, demonstrating that the species composition differed from that of surface water. The number of collected microalgae species varied depending on the fiber materials, with nylon containing all the adhesive microalgae. In contrast, only a few microalgae were observed in other fibers. These results suggest that, of the tested fibers, nylon material may be suitable for collecting adhesive microalgae. As a result, this study may be useful for future research on adhesive microalgae.

This paper is an experimental study on the optimal operating conditions of direct charging type electrospray for particulate matter collection. To perform the research, a direct charging type electrospray visualization system was configured to photograph the spray shape of microdroplets, and experiments were performed with varying electrode distance, flow rate, and applied voltage, which are the main factors affecting the particulate matter collection efficacy. Through image processing, the total number of microdroplets according to each condition was analyzed, and the number of microdroplets with a diameter of 1.5 mm or less was confirmed. In addition, by calculating the number of microdroplets per power consumption according to the applied voltage, the optimal operating conditions were derived in terms of energy consumption efficacy, and the microdroplet size distribution was analyzed under the optimal operating conditions. As a result of the experiment, it was confirmed that the optimal operating condition was at a flow rate of 10 mL/min and a voltage of -20 kV in case of 5 mm electrode distance, and at a flow rate of 15 mL/min and a voltage of -30 kV in case of 100 mm electrode distance.

Korean university libraries are increasing their library collection each year according to the standard set by the Ministry of Education. The standard states that all the university libraries are required to keep 3 books for newly enrolling students, 30 books for each enrolled student and 5, 000 books for each department. The increasing number of the university library collection brings many problems in the libraries. 1. The size of the library collection is not related to the satisfaction of the library user's requests. The satisfaction is usually related to number of the new publications received in the library. Z. The Korean publication is limited to a small number. It could not meet the university standard. Therefore, the number is filled with the foreign publications. But the use of them is not frequent. Even the number of the domestic and foreign new publications together could not meet all the requests of the university library users. Only cooperation with other libraries will be able to meet most of the diversified requests. 3. Most of the present library collection are not likely to be used in the future and they should be eventually discarded. Present library administration put too much emphasis on the size of library collection and only the aquisition of the material is main concern of the university librarians. They need to consider other factors in the aquistion of the library collection. They should make their collection development in accordance with user's requests in addition to meet the university standard.

The study was to grasp features of new material applicable to housing space in the sustainable side by analyzing materialistic features of new material and features of sustainable material with sustainable new material. Through analysis on sustainable new material, the study deducted the below conclusion. First, through the precedent studies, the characteristics of sustainable materials have been classified into eight categories : friendly healthiness, non-toxicity, comfortableness, naturality, recycling, harmlessness of environment, separate collection, reusability. After the criteria have been brought up from new material applicable to housing space in the sustainable. Second, in materialistic Characteristics of new material, 'New Process' was mainly applied. There was no any new material applied to 'new raw material'. Therefore, it is thought that it is necessary to study on development of perfectly new material and to study on new material to apply material used in other fields to finishing material of dwelling space. Third, in Characteristics of sustainable material, 'Re-serviceability' appeared most and 'Non-toxicity' and 'Recycling' appeared in the next. 'Friendly Healthiness' and 'Separate collection' appeared only one on the other side. Therefore, it is judged that it is necessary to develop and study new material including health components considering user's health, function for health increase and function to grope comfort for humans. Finally, after researching and analysis the criteria by recently presented the new material, it has been concluded that the standard can be used as the criteria of new material for the possibility of application in housing space. On the basis of the study, the author will carry out analysis on sustainable new material minutely and utilize it as basic data to suggest a standard of sustainable new material applicable to dwelling space in the future.

In recent years, for the purpose of solving the problem regarding environment protection and resource saving, certain measures and policies have been promoted to establish a green supply chains (GSC) with material flows from collection of used products to reuse of recycled parts in production of products. In this study, we propose an optimal operation of the GSC while considering the collection incentive of the used products and quality for recycling of used products. Two types of decision-making approaches are used for product quantity, collection incentive of used products and lower limit of quality level of reusable parts in the used products for recycling in the GSC. One is the decision-making under an independent policy in decentralized supply chains where a retailer and a manufacturer make decisions so as to maximize profits individually. The other is the decision-making under a cooperative policy in centralized supply chains where a retailer and a manufacturer make decisions cooperatively so as to maximize the whole system's profit. Additionally, we also discuss supply chain coordination as a manufacturer-retailer partnership based on profit sharing. Furthermore, we show the effect of the quality of the reusable parts on the optimal decisions. The collection incentive of the used products was found to bring more profitability to the GSC activity.
