This study investigated the effect of bamboo leaf powder, added at content of 0%, 3%, 6%, 9% and 12%, on the quality and sensory characteristics of rice cake imprinted with flower pattern (Ed-there is no respecitive comparison here) The chemical composition as a whole was 3.07${\pm}$0.12% of moisture, 5.87${\pm}$0.02% of crude protein, 2.52${\pm}$0.05% of crude fat, 23.70${\pm}$0.07% of crude fiber and 7.73${\pm}$0.02% of crude ash. With increasing amount of added bamboo leaf powder, the hardness and chewiness of the cake were significantly increased(p<0.05), while the cohesiveness, springiness and adhesiveness were decreased. In chromaticity, the L-value, the indicator of brightness, was significantly decreased with increasing bamboo leaf powder content. The a-value, the indicator of redness, was significantly lower than the chlorophyll color (p<0.05). The b-value, the indicator of yellowness, was increased indirect proportion to the content. In sensory test, the sensory characteristics such as color, flavor, taste and chewiness were all stronger with increasing powder content, whereas the softness and dampness were weaker. The greatest overall satisfaction was achieved by the sample group of cake with 6% preference added powder.

Objective of this study was to monitor the hydrogen sulfide production rate and concentration in anaerobic co-digestion of swine manure and food waste for biogas production in order to alternate the petroleum based energy. Anaerobic co-digestion for biogas production was performed in serum bottles at 2% volatile solids (VS) concentration and various mixing ratios of two substrates(swine manure: food waste = 100:0 ~ 0:100). Although hydrogen sulfide production rates were varied with digestion periods at different treatments, it was observed that hydrogen sulfide produced in the swine manure alone was lower at 2.4 fold than that of food waste. For effects of hydrogen sulfide concentration in the different mixing ratios of swine manure to food waste, the higher food waste ratio the higher hydrogen sulfide concentration. Also its average concentrations were varied from 0.1452% in the swine waste only to 0.3420% in the food waste alone. For the composition ratio of bio-gas in their anaerobic co-digestion, it appeared that there was 53.2% of $CH_4$, 23.9% of $CO_2$, 0.3% of $H_2S$ and 22.7% of miscellaneous gases including moisture.

The purpose of this study was to evaluate the effect of different saccharides on the quality of apricot sulgidduk. Appearance color of honey-added group as compared to other samples in apricot sulgidduk were preferable and scanning electron microscopy exhibited smaller pores. pH and acidity of white-added group immediately after preparation were higher than those of other groups. Higher moisture contents of honey-added groups during storage were found but total bacterial counts immediately before storage were 1 log cycle lower than that of other samples. The highest 'L' values were found for white sugar added group but the highest 'a' and 'b' were for yellow sugar-added sample. In mechanical characteristics of apricot sulgidduk for 48 hrs during storage at $20^{\circ}C$, hardness, gumminess and brittleness were higher in oligosaccharide-added sample as compared to other samples, while cohesiveness and springiness were the highest in honey-added group. In sensory evaluation of the sulgidduk, honey-added group obtained the highest score in color, sweet taste, moisture, after swallowing and overall quality (p<0.05) These results suggest that apricot sulgidduk with honey can be used as commercially successful rice cakes.

In this study, we present an algorithm that conducts an unique naming process for the bridge object through the solid object identification focused on 3D straight bridge model. For the recognition of 3D objects, the numerical algorithm utilizes centroid point, and solid object on the local coordination system. It classifies the object feature set by classifying the objects and members based on the bridge direction. By doing so, unique names, which contain the information about span, members and order of the object, were determined and the suitability of this naming algorithm was examined through a truss bridge model and a bridge model with different coordinate systems. Also, the naming process based on the object feature set was carried out for the real 3D bridge model and then was applied to the module on local server and mobile device for real bridge inspection work. From the comparison of the developed naming algorithm based on object identification and the conventional one based on field inspection, it was shown that the conventional field inspection work can be effectively improved.

The film scholar Vincent Amiel divides into three types of montage through his book The Aesthetics of Montage ; Montage narratif, Montage discursif, and Montage decorrespondances. These three categories are the concept that encompasses the aesthetic class to which most movies belong. Early films pursued the essential and basic functions of editing, which tend to be modified in the direction of enhancing the director's goals over time. In this way, "Expressive Montage" is one of most important concepts of montage, not as a 'methodology' that combines narrative but as a 'purpose'. In the montage stage, the expressive montage work is done through three steps of decision. The process of 'combining' to combine the selected films in a certain order, after the process of 'selection' which selects only necessary parts of the rush film, and 'connection' to determine the scene connection considering the duration of the shot. The connection is the final stage of the montage. There are exceptions, of course. When fiction films of classical narratives use close-ups, or when using models or objects of neutered animals, the film induces the tendency of a "montage decorrespondances" rather than a "montage narratif" or "montage discursif". This study attempts to analyze the tendency of montage of works with 'uncertain connection' through 'collage' used by close-ups and montage decorrespondances as 'fragmentation tendency of modern films'. The fragmentation of the montage in contemporary film breaks the continuous and structural nature of the film, and confuses the narration structure that is visible on the surface of the film. The tendency of the fragmentation of the montage, which started from this close-up, seems to give an answer to the extensibility of the modern image.
