본 논문에서는 퀄컴의 Vuforia 엔진을 이용한 증강현실 미로 찾기 어플리케이션을 제안하고 구현하였다. Vuforia 엔진은 증강 현실 엔진 중 비교적 최근에 만들어져 다양한 마커를 활용할 수 있으며 속도, 마커 인식 면에서 다른 AR 엔진에 비해 뛰어나다. 본 논문에서는 Vuforia 엔진에 기반한 미로 찾기 앱을 설계하고 구현한다. 제안한 방법에서는 스마트폰으로 이미지 마커를 인식한 후, 스마트폰 화면에 3D 캐릭터와 미로를 출력해주도록 한다. 또한 가속도 센서를 이용하여 사용자가 직접 스마트폰을 기울여 캐릭터를 목적지까지 이동시키는 미로 찾기 게임 어플리케이션을 구현하였다.

Milk is an emulsion, improving texture of surimi mixture and able to suppress off flavors and abnormal tastes. Therefore, this study aimed to identify the effective properties of milk in the preparation of a surimi mixture for 3D printing. The sensory and physical properties of surimi mixtures containing 0%, 20 wt%, and 40 wt% milk were evaluated, where the unheated surimi mixture with added milk demonstrated increased firmness and adhesiveness compared to the negative control group. In addition, the hardness, adhesiveness, gumminess, and chewiness of the mixture containing 40% milk were highest, but springiness, cohesiveness, and resilience were lowest. In the sensory evaluation, as the amount of milk increased, a fishy smell, abnormal taste and texture improved, hardness and preference increased as well. From these results, it was confirmed that a surimi mixture can be prepared with milk to improve its physical and sensory properties for 3D printing when compared to the negative control mixture. In particular, it was revealed that the physical properties and preference of the surimi mixture are best when prepared with 40% milk.

Experiments were conducted to study on bionomics and control of cutworms; Agrotis tokionis, A. ipsilon, A. fucosa in Suweon, 1978-1979. A. ipsilon and A. fucosa had two or three generations and A. tokionis had one generation a year. A large number of A. toikonis occured at the end of September, and the major peaks of the first generation of A. tokionis and A. fucosa were in mid-June, the second generation in mid-August, and the third generation was at the end of September. These cutworms laid many eggs on the lower surface of curved downward leaf of Chinese cabbage and the larvae later than 3rd instar began to cut the basal part of stem and then pulled into the soil. A parasite of A. tokionis, a braconid wasp, Meteorus rubens, and two unidentified Ichneumnid wasps were found. Mocap and Volaton gave effective control to the cutworms but Volaton should be applied not to contact with plant.

Previous studies based on the theoretical evidence and based on the empirical data have been constantly revealing related factors affecting visual fatigue in viewing 3D images. however, the measurement data coupled with the factors that affect the viewers to feel fatigue is insufficient. this study research that the viewers feel the visual functional data is based on subjective fatigue such as IPD, AC/A ratio, and the degree of phoria and the effects on variance in these data, is to examine the correlation between these data. based on the average score of subjective fatigue which is $6.00{\pm}3.88$, total fatigue points from 0 up to 6 is classified as a group not appealing for the fatigue and from 7 up to 16, they were classified as the fatigue appealing group. the results showed no difference in satisfaction of the images by each subjective fatigue, IPD and far phoria. AC/A ratio was higher from the fatigue not appealing group, near phoria was higher from the fatigue appealing group. after watching 3D images, the fatigue not appealing group showed a tendency of higher increase of exophoria. correlations appeared in this experiment showed that AC/A ratio and near phoria are closely related to level of subjective fatigue which feel when watching 3D images. when watching 3D images based on two data appear to be able to predict the fatigue, even during content production fatigue reduce the data dimensions to be used as the main basis is expected.

Information Grid that connects Sensor Grid and Shooter Grid with network is the core infrastructure to enable the NCW concept. The U.S. DoD(Department of Defense) has developed the GIG(Global Information Grid) as the Information Grid that connects all of the DoD mission areas. Then the U.S. DoD has incrementally constructed GIG. In this respect, the case of the U.S. DoD's GIG construction refers to materializing ROK Information Grid concept. Therefore we studied the U.S. DoD's GIG construction trend and analyzed ROK's GIG construction trend. In result this paper proposes the way to develop and construct ROK's GIG.

We performed an experiment of keeping the extension of raw and semi-dried flounder (Pleuronectes herzensteini). The effect of with (WG) or without gill (OG), drying degree (20% drying: 20D, 40% drying: 40D) and storage temperature($5^{\circ}C$) and 0.1% chitosan-ascorbate (CA) treatment of vacuum packaging flounder on the growth of contaminated microorganism during storage for 10 days were investigated. Total aerobacter (TA) in the OG-treated raw flounder was $0.29{\sim}0.44$ log cycle lower than that of WG-treated flounder. Also, the number of Staphylococcus aureus (SA) and E. coli (EO) in OG were lower compared with WG. The number of TA, SA and EO in 20 D among 0 D, 20 D and 40 D stored at $5^{\circ}C$ were lowest. Especially, the SA and EO was $0.13{\sim}0.53$, 0.3-0.88, and 0.13-0.74 log cycle lower compared with raw flounder. The growth of TA, SA and EO separated from raw flounder in tryptic soy broth were completely inhibited by 0.1% CA. The anti-biotical effect of CA of two microorganisms SA and EO that separated from flounder, and the growth of all of them were 90% (SA), 96% (EO) inhibited at the 0.1% CA. The inhibition times at $37^{\circ}C$ in soy broth was 36 hr. However when CA was added directly to flounder, it appeared inhibition effect to 0.88 log cycle. The effect of CA was better when gills removed and 20% drying.

By using the trade in value-added(TiVA) database and employing social network analysis, this paper analyzes changes in global trade to be triggered by the Belt and Road Initiative (BRI) and the US-China trade war. The main results are summarized as follows. First, the BRI will help maintain China's core position as the world's manufacturing hub, and will strengthen Europe's service industry capabilities within the global value chain(GVC) network. Second, the US R&D industry, US wholesale and retail industries, and Germany's automobile industry were considered the most influential industries in the GVC network during the 1995-2011 period, and will retain their status until 2049, when the US-China trade war and the BRI are reflected. Third, the increase of the number of communities shows that the BRI might spur fragmentation of the production process. Finally, community structures of inter-industry trade relations, including China's electronics industry, Germany's automobile industry, and US R&D, show important features that are related to the competiveness of each country's service industries.

3D-based information is needed increasingly as well as 2D Information as cities grow and buildings become large and complex, and use of 3D-models is getting attention to handle such problems. However, there are limitations in using 3D-models because most applications and research efforts using them have been for visual analysis. This study presents a method to find optimal paths in indoor spaces as an illustration for using 3D-models in spatial analysis. We modeled rooms, paths and other facilities in a building as individual 3D objects. We made it possible to find paths based on network structure by integrating the vector-based networks of 2D-GIS and 3D-model.
