On account of increasing interest of substantiality in these day, it is needed to make an effort to establish an environmentally sustainable production system for the construction works. Although practical affairs and researches are in progress to reduce and recycle construction wastes, as a result of a research, there are still obstructive factors on waste reduction and recycling which they don't interact efficiently between waste disposal process of the construction area and waste disposal company. As a plan to revitalize reduction and recycling of construction wastes, this research focuses on finding obstructive factors and giving solutions to reduce and recycle construction wastes which comes from construction process and construction industries. To meet the needs of the research, firstly relatively significant construction wastes (concrete, soil, brick, block, asphalt, plastic, lumber) were identified. On site level interviews with management of disposal companies and construction sites were conducted as well, focusing on typical waste disposal process. Throughout this interviews, obstructive factors were conducted. A result of the research, the authors suggest an improved approach on disposal and recycling for construction waste by prioritizing the identified factors and ranking the importance level of each factor. And, by identifying factors obstructing reduction and recycle of construction wastes, this research suggests improved disposal process of construction waste.

As the market of educational pet insects is expanding, understanding the consumer needs became more crucial. To achieve the ideal analysis on the market, this research monitored the behavior of consumers. The posting on the blogs of consumers, who have visited insect museums and farms, or have bought insects were collected as data. Moreover, the informational contents, photographs and texts, were analyzed. The results showed that the family-unit visitors with elementary school lower graders were the main type of visitors for their children's education. The visiting areas were concentrated in Seoul and the Metropolitans of Gyeonggi province, and the visits were mostly occurred during their children's vacation period. The analysis of posted photographs showed the visitors' high interest in the hands-on program. According to the texts on visitors' blogs, especially, the largest number of visitors satisfied with the variety of program. It implies the necessity of development in diverse and differentiated hands-on program. Otherwise, the programs available to connect insects to other animals and plants should be introduced to reduce aversion against insects, which was reported as the strongest dissatisfaction. In conclusion, diversification on insect species and development in systematized hands-on program seem to be required for the continuous growth of educational pet insects market.

The land area, which is on the inner side of the water line, is controlled to a certain degree due to the purposes of space utilities controllers' respective roles, but the sea area is not so much controlled as the land area. However, as interest in the security and utility of the marine space, as well as that in the consistent development of the land space, has increased, there has been increase of the requirement for information about marine data and environment. The object of this study, Busan, plays various roles such as a harbor and bay, a tourist resort, and a port unlike coastal seas of other areas, and thus needs systematic control because it has numerous environmental factors. However, there are limitations in the number of data about Busan coastal sea constantly provided while the acquisition of data from main points and many areas is important for the analysis of marine contamination in Busan coastal sea area. Thus, using nautical charts with numerical values in preparing increase of the demand of them according to the degree of information requirement for the analysis of the changes in coastal areas, this study constructs property data and space data by combining vertex data about Busan's 17 coastal sea areas provided by NFRDI, and tries to present the analytical techniques for grasping the environmental conditions and continuity of the coastal areas and methods of their utilities, using GIS Geostatistical Analysis Technique.
The needs for drawing up of biotope map is rapidly spreaded over each local government recently in Korea, according as enhancing of interest about biotope, which is recognized to practical instrument for concretely being able to considering natural environment and ecosystem on all sorts of development plan. However, there are not yet the standard suggestion on biotope types and classification systems and biotope classification criteria. Therefore, each other methodologies are applied to each of local autonomies. First, under such critical mind the biotope types and classification systems were drafted by a review on biotope types, biotope classification systems, and biotope classification criteria of the preceded case studies until now at the inside and outside of the country. And then the purpose of this study is to derive biotope types and biotope classification systems applicable to the whole Korean region through continual feed back such as field surveys in selected representative areas and consultations. As a result of reviewing the case examples, first, the biotope classification systems were mixed two steps system with three steps system and those were composed mostly of the structure of two steps: large and small. Second, land-use, soil pavement ratio, green cover ratio, and vegetation usually were applied to the biotope classification criteria. This study suggests that the biotope classification system is consisted of four steps system: large(biotope class), medium(biotope group), small(biotope type) and detail(sub-biotope type), and the biotope types are classified into 13 types of large step, 45 types of medium step and 127 types of small step. However, this study suggests that the new biotope types on small step or detail step should be continually supplemented with the foundation of classification system proposed in this study because the biotope type classification should consider regional characteristics.

Polymer/ceramic composite is of great interest as a dielectric material for embedded capacitors. This paper is concerned in the effects of $BaTiO_3$ particle size on epoxy/$BaTiO_3$ composite films for embedded capacitors. 6 different size powders smaller than 1 $\mu\textrm{m}$ in diameter and bisphenol-A type epoxy were used for this experiment. Dielectric constant of the epoxy/$BaTiO_3$ composite capacitors increases as the powder size increases at the same powder loading, which is due to the increase of tetragonality of the powders as particle size increases. And leakage current of the capacitors also increases dramatically as the powder size increases. It was explained that this is due to the decrease of the number of $BaTiO_3$epoxy/$BaTiO_3$ potential barriers per unit length and, moreover, the enhancement of potential barrier lowering effects caused by increase of potential drop per one barrier. As a result, there is tradeoff between high dielectric constant and low leakage current in the epoxy/$BaTiO_3$ composite capacitors. So it is important to select proper size $BaTiO_3$ powders in accordance with needs.
