Video content is divided into long-form video content and short-form video content according to the length. Long form video content is created with a length of 15 minutes or longer, and all frames of the captured video are included without editing. Short-form video content can be edited to a shorter length from 1 minute to 15 minutes, and only some frames from the frames of the captured video. Due to the recent growth of the single-person broadcasting market, the demand for short-form video content to increase viewers is increasing. Therefore, there is a need for research on content editing technology for editing and generating short-form video content. This study studies the technology to create short-form videos of main scenes by capturing images, voices, and motions. Short-form videos of key scenes use a pre-trained highlight extraction model through machine learning. An automatic video editing system and method for automatically generating a highlight video is a core technology of short-form video content. Machine learning-based automatic video editing method and system research will contribute to competitive content activities by reducing the effort and cost and time invested by single creators for video editing

As concrete forms, panel forms made of plywood used to be widely used, but recently a system form made of aluminum has been broadly adopted because of the advantages it offers in terms of constructability and economy. However, an aluminum form reacts with concrete, which is alkali, and creates hydrogen gas. As a result, air pockets occur on the concrete's surface, and its finishability deteriorates. Therefore, this research analyzed the relationship between the distribution of voids and surface roughness and the damage degree and number of uses of the aluminum form. The analysis of the distribution of voids shows that the number of voids of 0.1~1 mm, which are considered to have occurred because of chemical reaction, was 200~500 on the coating plywood, but was 1 500~2 000 on the aluminum form after 3 uses, and impossible to count after a higher number of uses. Surface roughness was $1.7{\sim}3.2{\mu}m$ on the coating plywood form, but was about $2.6{\mu}m$ after the first use and about $6.8{\mu}m$ after 10 uses, a 2.6-fold increase. Distribution of voids did not show a particular tendency depending upon the degree of damage to the concrete form, but surface roughness showed an increasing tendency as the degree of damage grows. Therefore, when using aluminum forms, surface maintenance should be carried out completely, such as prevention of damages to the form surface coating materials and spreading of separating materials on forms.

Among the members of the inhibitor of apoptosis (IAP) protein family, only Livin and survivin have been reported to have variant forms. We have found a variant form of c-IAP2 through the interaction with the X protein of HBV using the yeast two-hybrid system. In contrast to the wild-type c-IAP2, the variant form has two stretches of sequence in the RING domain that are repeated in the C-terminus that would disrupt the RING domain. We demonstrate that the variant form has an inhibitory effect on TNF-mediated $NF-{\kappa}B$ activation unlike the wild-type c-IAP2, which increases TNFmediated $NF-{\kappa}B$ activation. These results suggest that this variant form has different activities from the wild-type and the RING domain may be involved in the regulation of TNF-induced $NF-{\kappa}B$ activation.

It had been disputed how to apply wall drag to the dispersed phase in the framework of the conventional two-fluid model for two-phase flows. Recently, Kim et al. [1] introduced the volume-averaged momentum equation based on the equation of a solid/fluid particle motion. They showed theoretically that for dispersed two-phase flows, the overall two-phase pressure drop by wall friction must be apportioned to each phase, in proportion to each phase fraction. In this study, the validity of the proposed wall drag model is demonstrated though one-dimensional (1D) simulations. In addition, it is shown that the existing form loss model incorrectly predicts the motion of the dispersed phase. A new form loss model is proposed to overcome that problem. The newly proposed form loss model is tested in the region covering the lower plenum and the core in a nuclear power plant. As a result, it is shown that the new models can correctly predict the relative velocity of the dispersed phase to the surrounding fluid velocity in the core with spacer grids.

The purpose of this study was to investigate characteristics of behavior of nutrients such as TN (Total nitrogen), TDN (Total dissolved nitrogen), TP (Total phosphorus) TDP (Total dissolved phosphorous) in runoff water from a nonpoint source dominated watershed ($6.67\;km^2$). Regular and intensive flow measurement and water sampling were taken during two years (February 2002 to January 2004) in the Ingyeong River, a tributary of the Han River. The mean concentrations of nutrients during rainy days were significantly (p < 0.05) higher than those during dry days. The mean TDN/TN ratio in rainy days (95%) is almost identical to that in dry days (96%), but mean TDP/TP ratio in rainy days (24%) significantly decreased compared with that in dry days (66%), suggesting that dominant form of TP is shifted from dissolved form to particulate form. Accordingly, the measures (.eg. filter strips, cover crops) to reduce soil erosion for fallow upland in the rainy season should be taken to control particulate phosphorous.

In contemporary society, heterotopia is the law dominates thoughts and is the concept reconstituted spaces calls order in chaos. And that is the place which refuses the paradoxical and social custom and sometimes poses a danger and rise in rebel. The purpose of this study is to study how forms of clothing fluid form images are expressed in modern fashion develop body around in the spatial relationship between the body and its environment. The study method consider changed characterastics of fluid space through the heterotopia thinking system of Foucault Michel. Based on this method, the heterotopia space that appeared in the plastic arts in aspects of artistic significance and aesthetic value was examined. Based on the above discussion on modern fashion Fluid Form were expressed in any formative characteristics were considered. The results of this study are as follows. Fluidity is the transformed interaction. It expanded external representation of organic body structure and reconstructed flexible forms of dynamic structures continuously. Transformation is the new space structure. It constructed invisible transformation and developed convertible dress space by combining a variety of functional overlap and fold. Deconstruction was expressed structural forms, expanding the existing forms in the open structure which have ambiguous boundaries.

The preliminary study for providing the relationship of the factors which are climate and the pteridophyta was carried out. Dormancy form and leaf phenology of the 321 taxa belonging to 27 families were analyzed. This survey shows life-form spectrum of Korean ferns. The results obtained from this study were as follows: Deciduous (d), Evergreen (e) and Summer-deciduous (sd) were calculated as 37.4%, 59.2%, 1.9%, respectively and the Evergreen (e) has the highest value compared to the other leaf phenologies. It observed from the life-form spectra that Hemicryptophytes (H) was the most common dormancy form at 42.1%. Geophytes (G), Epiphytes (E) and Chamaephytes (Ch) were calculated at 25.5%, 15.9%, and 11.8%, respectively. There will be a discussion about geographical distribution of Korean ferns and possibility of their distribution range.

The moment responses of electric pole foundations for a railroad were investigated using real-scale load tests. Large overturning moments were applied to two square rigid piles with a 1.1 m width and a 2.2 m embedded depth. Two different installation methods-with and without a form-were applied to evaluate the influence of the form work on the moment capacities of the foundations. The reduction of ground strength caused by the excavation without a form is more pronounce than the decrease of frictional strength due to the smooth concrete surface with a form. From the test results, it is found that the current design method which applies a proportional coefficient to consider the effect of a form work is not appropriate. When the normal and frictional stressed is considered separately, the effect of a form work can be estimated reasonably by reducing the friction angle between soil and foundation by 20%.

The restorative treatment using titanium implants has become a standard procedures in everyday clinical practice. However, there are several concerns about the use of titanium as a materials. Above all, the grayish metal color provokes esthetic problems when the soft tissue around the implants is not optimal. Recently, zirconia has been emerging as an alternative to titanium due to its white color and superior physicochemical properties. In this paper, the current findings about zirconia implants was reviewed based on the results from animal and clinical experiments. In addition, the immediate implantation protocols using the natural tooth form zirconia implants was introduced as a novel procedures and future perspectives were discussed.
