This study aims to analyze the characteristics of the male products for urinary incontinence by examining the types and characteristics of those registered in KIPO (Korean Industrial Property Office). Additionally, the types and characteristics, especially for the cloth products and the pads, of male panties for urinary incontinence on the market are analyzed. Men in their 60s with minor symptoms were selected as the subjects to evaluate the wearability. The results are as follows. 11 male products for urinary incontinence, registered in KIPO, are structurally different from those for women by having a separate pocket mainly for absorption. There are one disposable type and 7 cloth types, and the cloth panties can be classified as either united or separable type depending on the detachability of pads from the panties. The types of the panties vary according to the position, shape, and size of the attached pads on normal male panties (boxer, briefs, drawers). The fabrics for the urinary incontinence are usually piled in 3 to 5 layers by having the most absorptive layer on the top, the next with deodorizing characteristics, and the bottom with the waterproof fabric as basics with some additional layers of antibiotic or breathable fabrics. From the wearability test, it has been determined that the panties are not distinguishable in external appearance and the fitness is also not a problem since the size varies as the normal panties. It has been evaluated that the fitness of the panties is an important factor since the pad should be worn in any form; the pad sewed in the middle of the panties was evaluated to be more wearable than having a long pad. In case of separable panties, when the pattern and fabric is similar to the functional panties and the options such as the thickness of the pads or detachability are given to the users, it tends to be more satisfactory.

In order to the comparative morphological study of the non-ciliated and ciliated epithelial cells, and to elucidate the process of degeneration of non-ciliated epithelial cell of the ductus epididymidis, Korean striped field mouse, Apodemus agrarius coreae was examined with light and transmission electron microscopes. The morphological characteristics of non-ciliated epithelial cell, the cell types of the caput epididymidis (Cp), corpus epididymidis (Cr) and cauda epididymidis (Cu) were long-columnar, short-columnar and short-cuboudal, respectively. The mitochondria and rough endoplasmic reticulum tended to be broken as they immigrated from Cp to the Cu. The Golgi acted vigorously at the Cp, but the Golgi was inactive in Cr and Cu. The secretory vesicles and lysosomes were increased gradually from Cp to the Cu. The process of degeneration of the non-ciliated epithelial cells observed in the Cp, Cr and Cu epididymidis. The increase of the non-ciliated epithelial cells, and its degeneration were observed more often from Cp to the Cu. The morphological characteristics of the ciliated epithelial cells, the cell types of the Cp, Cr and Cu were long-columnar, short-columnar and short-cuboudal, respecptively like the non-ciliated epithelial cells. The stereocilia was long and slender at the Cp and Cr, while Cu was very short. The pinocytotic vesicles and absorptive vesicles were increased from the Cp to the Cu. Numerous disintergrated products was existed at the Cr including the Cp, but Cu were not observed. A significant amount of lysosomes existed at the Cp and Cr epithelial cells, but they were not observed in Cu epithelial cells.

In this study, plastic detection technique was developed, applying remote sensing technology as a method to extract plastic wastes, which is one of the big causes of concern contributing to environmental destruction. It is possible to extract areas where plastic (including polypropylene and polyethylene) wastes are prominent, using ASTER data by taking advantage of its absorptive characteristics of ASTER/SWIR bands. The algorithm is applicable to define large industrial wastes disposal sites and areas where plastic greenhouses are concentrated. However, the detection technique with ASTER/SWIR data has some research tasks to be tackled, which includes a partial secretion of reference spectral, depending on some conditions of plastic wastes and a detection error in a region mixed with vegetations and waters. Following results were obtained after making comparisons between several detection methods and plastic wastes in different conditions; (a)'spectral extraction method' was suitable for areas where plastic wastes exist separated from other objects, such as coastal areas where plastic wastes drifted ashore. (single plastic spectral was used as a reference for the 'spectral extraction method') (b)On the other hand, the 'spectral extraction method' was not suitable for sites where plastic wastes are mixed with vegetation and soil. After making comparison of the processing results of a mixed area, it was found that applying both 'separation method' using un-mixing and ‘spectral extraction method’ with NDVI masked is the most appropriate method to extract plastic wastes. Also, we have investigated the possibility of reducing the influence of vegetation and water, using ASTER/TIR, and successfully extracted some places with plastics. As a conclusion, we have summarized the relationship between detection techniques and conditions of plastic wastes and propose the practical application of remote sensing technology to the extraction of plastic wastes.

Suspended sediment transport plays principal roles in morphological process of natural coastals. It is needed to understand the reason why interaction characteristics of solitary wave and suspended sediment. The present study shows that suspended sediment pickup derived on solitary wave celerity. The 2D prismatic open channel length is 12 m, width is 0.8 m, height is 0.75 m and slope is 1/6. Generation of solitary wave is used by rapidly opening the sluice gate. Bottom surface sediments are laid movable slope section by 0.03 m thickness and experimental sediments are used anathracite and jumoonjin sand. Techniques of suspended sediment pickup rate are designed equipment ASC(Absorptive Suspended sediment Collector). It could directly absorb 5 points suspended sediment by channel water depth. Solitary wave celerity is measued by ADV(Acoustic Doppler Velocimeter). Mounted two video cameras(Model No. : Sony, HDR-XR550) are used to image processing of suspended sediment concentration and turbidity. Suspended sediment pikcup rate(Einstein, 1950) is analyzed to nondimensionalization based on solitary wave celerity. The suspended sediment pickup rate is suggested that more effective plunging breaking type than spilling. The results indicates fundamental suspended sediment transport mechanism between solitary wave celerity and suspended sediment pickup based on laboratory experiments. Finally, the present study suggests that suspended sediment pickup rate by solitary wave is used only characteristics of sediment and solitary wave celerity.

Literatures on open innovation have two major limitations. First, either on a firm level or on an industry level did they analyze the open innovation issues. The results of a firm's innovation can be diffused through the whole network and the firm can learn back from the network knowledge. Prior literatures did not consider the feedback loop among firms and network in which the firms are involved. Second, most open innovation research had a static perspective on firm's innovation performance. Since the diffusion, spill-over and learning among network members are involved over time, the open innovation is intrinsically dynamic. From the dynamic perspective, we can appreciate the fundamental attributes of the open innovation network which involves diverse firms, research institutes, and universities. In order to overcome the limitations, we suggest a dynamic model for open innovation network. We build an agent-based model which consists of heterogeneous firms. The firms are connected through a scale-free network which is formed by preferential attachment. Through the diverse scenario of simulation, we collect massive data on the firm level and analyze them both on firm and industry level. From the analysis, we found that, on industry level, the overall performance of open innovation increases as the internal research capability, absorptive capacity, and learning curve coefficient increase. Noticeably, as the deprecation rate of knowledge increases, the variability of knowledge increases. From the firm level analysis, we found that the industry-level variables had a significant effect on the firm's innovation performance lasting through all the time, whereas the firm-level variables had only on the early phase of innovation.

지식 네트워크는 지역의 경제적 성과와 경쟁력을 확보하는데 중요한 요소로 간주된다. 또한 지식을 흡수할 수 있는 능력이 높은 연구기관들은 지역적 요인에 상관없이 글로벌 지식 네트워크를 형성하려는 경향이 강하며, 그렇지 않은 기관들은 지역적 요인에 많은 영향을 받는다. 본 연구에서는 한국의 지역을 중심으로 지식 흡수능력이 낮은 기관일수록 지식 네트워크의 지리적 요인에 얼마나 많은 영향을 받는지에 대해 검증하였다. 그 결과, 지식 흡수능력이 높은 기관일수록 국제 공동연구를 추진하고 있는 것으로 나타났으며 수도권을 제외한 다른 지역에서는 거점 대학을 중심으로 연구가 진행되고 있는 것으로 나타났다. 즉, 과학기술이 발전된 지역은 더 이상 반드시 지역적인 요소가 중요 요인이 아니라는 것을 의미한다. 이러한 연구결과는 상당부분 선행이론들의 논의와 부합하는 것으로 나타났다. 또한 사전연구에 대해 한국 지역을 중심으로 사례연구를 진행하여 이를 검증하였다는 점에서 연구의 가치가 있다.
