The purpose of this study was to collect and analyze information on the major scoring paths, success rate by shooting type, assist, steal, block, and goalkeeper defense rate by shooting type in the 2019 World Women's Handball Championship. Based on the research results, the following conclusions were drawn. First, as a result of the analysis of the scoring route, 1st the Netherlands and 2nd Spain had 6m shots and 7m shots the most. Second, in the success rate analysis results by shooting type, the top 6 teams showed 7m shot, breakthrough shot, and fast shot. Third, according to the result of assist frequency analysis, the fourth place in the competition Norway scored the most assists among the six teams. Fourth, as a result of the steel frequency analysis, Norway scored the most with 5.2 on average among the six teams. Fifth, as a result of analyzing the goalkeeper defense rate by shooting type, it was found that all 6 team's goalkeepers had the highest defense against 9m shooting. Therefore, for an in-depth analysis of the game strategy, it is considered that it is necessary to understand the characteristics of individual player's performance and collect information will be followed by a follow up research in the future.

Effects of growth regulators, scion length and scion diameter on shooting and seedling characteristics were investigated to increase seedling products by root cuttings of lacquer tree. Shoots developed and emerged above-ground from the root scion at 3∼5 weeks after cut plating, most of that was a shoot but some of that were 2∼3 shoots. Otherwise, non-shooting was the reason that cortical layer was decayed. Soaking in zeatin was the most effective on shooting of root cuttings and high concentration was effective. Also soaking on high contents of BA or kinetin was effective on shooting but was lower totally than soaking on zeatin. Seedling characteristics among 3 growth regulators and 3 concentrations were not any difference in statistical significant, but were move excellent than control. As root scion was tall, shoots were developed at early. 15cm length scion was the most excellent to use seedlings but 3cm length scion was wickedness. 10cm scion, however, was highest to product of seedlings than any others. 0.3∼0.5 cm length scion was showed 76% shooting rate at 10 weeks after cut planting, but seedling characteristics were not any difference among the kind of 3 diameters.

Recently, the metaverse has been receiving a lot of attention. Metaverse means a virtual space, and various events can be held in this space. In particular, 360-degree video, a format optimized for the metaverse space, is attracting attention. A 360-degree video image is created by stitching images taken with multiple cameras or lenses in all 360-degree directions. When shooting a 360-degree video, a variety of shooting equipment, including a shooting staff to take a picture of a subject in front of the camera, is displayed on the video. Therefore, when shooting a 360-degree video, you have to hide everything except the subject around the camera. There are several problems with this shooting method. Among them, lighting is the biggest problem. This is because it is very difficult to install a fixture that focuses on the subject from behind the camera as in conventional image shooting. This study is an experimental study to find the optimal angle for 360-degree images by adjusting the angle of indoor lighting. We propose a method to record 360-degree video without installing additional lighting. Based on the results of this study, it is expected that experiments will be conducted through more various shooting angles in the future, and furthermore, it is expected that it will be helpful when using 360-degree images in the metaverse space.

A Cold Cathode Fluorescent Lamp(CCFL) is used as a LCD Monitor's backlight widely. The most common way to check CCFL's defects is an examination with the naked eye. This naked eye examination can cause examination inconsistencies and industrial disasters. A shooting environment and detection algorithms are important for finding CCFL defects automatically. This paper presents CCFL defect detection algorithms using images captured under the shooting environment with sidelight which is one of the shooting environment we have suggested. The experimental result shows 4.65% of overdetection and 5.37% of unsuccessful defect detection of CCFL.

3 dimensional stereoscopic is attracting new attention as it simulates human eye and related hardware advances. However, 3 dimensional stereoscopic requires more time and effort than 2D movie because it uses 2 cameras or 2 lenses. This study analyzed the merits and demerits of the system producing rider movie using 3 dimensional stereoscopic shooting techniques and searched a way to produce better 3 dimensional stereoscopic rider movie which meets the producing intention by applying elements required to create effective 3 dimensional stereoscopic effect. According to the study result, a light-weight integrated system was effective to create 3 dimensional stereoscopic rider movie because of its genre characteristic. In the post-production of the work, location shooting considered of time re-mapping, color correction and graphic element addition was required.

4K high speed camera shooting enables shooting of fast subjects in Full HD 4 times resolution without motion blur due to increase in resolution and shutter speed. However, this shooting incurs several limitations including focus, intensity of radiation and increase in data quantity. As lack of intensity of radiation may occur due to increased shutter speed, it is shoot by opening aperture and limitation in focusing follows. In addition, there is limitation in shooting records since it has restriction in storage due to increased resolution and frame rate. In this regard, this study aims to analyze the limitations shown above through production case of 4K high speed camera (Phantom Flex 4K) and to design effective workflow to overcome this.

The study examined the level of heavy metal contamination by dividing military rifle shooting ranges into the three areas, i.e firing, trajectory, and target. The target area was found to be contaminated at a level higher (Cu 845 mg/kg, Pb 30,487 mg/kg) than the Worrisome Level of Soil Contamination (hereinafter referred to as the “Worrisome Level”) The trajectory area was predicted to be free from contamination, but it did indicate contamination although it was pretty much lower (Cu 23 mg/kg, Pb 99 mg/kg) than Worrisome Level. This is attributed to the contamination spread when rearranging the soil of the target area during the maintenance of the shooting range. The firing area was also predicted to be free from heavy metal contamination, but the results analyzed indicated a contamination higher (Cu 201 mg/kg, Pb 2,286 mg/kg) than Worrisome Level. This is attributed to the fragments of the broken bullet scattering due to the pressure generated as the bullet leaves the muzzle. An examination of heavy metal contamination in the discharge area as well as gutters to prevent the intrusion of rain water from perimeter revealed a high level of contamination (Cu 298 mg/kg, Pb 6,497 mg/kg), which makes it necessary to take measures.

The fire at a Busan indoor shooting range on November 14, 2009 was reconstructed by using a computational fluid dynamics model for fire simulations, in order to investigate the cause of the heavy death toll in a short period of time. Spread of the flame and smoke, and temperature distribution obtained by fire simulation were compared with the results of fire investigation based on the CCTV recordings. The flame and smoke flew out violently through the door into the cafeteria from the shooting range, and the cafeteria was filled with smoke just within 3 seconds followed by the onset of fire. This is consistent with the CCTV recordings. It was confirmed, as a result, that people in the cafeteria did not have enough evacuation time. The computed temperature at the door knob reached about $1400^{\circ}C$, near its melting point.

This study was conducted to estimate rooting and shooting in single-node cuttings (SNC) of roses 'Rote Rose' and 'Teresa' to several conditions: growth stage, node position, and leaf area of cutting, so that single-stemmed roses (SSR) could be used in rose factory system. There was no effects of growth stage of flowering shoots far cutting on the rooting and shooting of SNC in both of the two cultivars. However, the node position and leaf area of cuttings significantly affected the rooting and shooting of SNC: the speed was accelerated with larger leaf area and upper node cuttings, but the rate showed little difference as above 95%. Based on above results, rooting and shooting in SNC was forced by leaf area mainly, followed by node positions. On the other hand, flowering rate of shoots from SNC was improved mainly with larger leaf area in cuttings. Shoots of 45cm-longer, qualified for rose factory system, increased with lower node and larger leaf area significantly. Therefore, it could be said that the potential growth of shoots from SNC would be influenced mainly by leaf area, followed by node position on cutting.
