포켓몬고 게임의 인기로 실외 증강현실 게임에 대한 관심이 높아졌다. 본 논문은 실외 증강현실 슈팅 게임을 위한 권총형 모션 컨트롤러와 이와 연동하는 증강현실 게임 콘텐츠를 소개한다. 기존의 증강현실 게임용 총 컨트롤러는 방아쇠 인터랙션만 지원하고 있지만, 제안하는 장치는 모션 인터랙션으로도 게임을 조작할 수 있어, 실외에서도 총기류를 이용한 슈팅 게임을 몰입하여 즐길 수 있다.

Previous research has identified the biological, psychological, and social factors that confer an elevated risk for suicide. Evidence suggests that sleep disturbances are one of the risk factors that predict an increased risk for suicidal behaviors. Both sleep disorders and general sleep complaints are linked to higher levels of suicidal ideation and depression, as well as increased rates of suicide and suicide attempts. The causal mechanism of this association is not clear. For example, it is not known if insomnia is an independent phenomenon that if interrupted could prevent the emergence of a mental disorder, or if insomnia is a symptom of another developing illness. Hypofrontality, HPA dysfunction, and an impaired serotonergic system are potential mechanisms underlying the association of sleep disturbances and suicidal behavior. Future research is necessary to examine the specific mechanism of this association between sleep and suicide, which may lead to an effective intervention and diminished suicide risk.

This study analyzed operation characteristics of air-condition piping is made by quick disconnect coupling. Air-conditioning consists of central compressor 3HP capacity and R22 refrigerant. We experimented with two operation cycles of air-condition under the same environment; one is with quick disconnect coupling. The other is without quick disconnect coupling. As a result, we can observe whether the condensation temperature of former increased by about 3-5. Furthermore, COP decreased by about 10%.

Under awareness of the importance of interaction between local research agencies and farmers in developing local agriculture, this study attempts to analyse the level of interaction in extension services of Experiment Station. The data were collected through the interview with researchers in five Experiment Stations and farmers who have made contact with the researchers. The results of the analysis are as follow: (1) The Experiment Stations are currently providing extension services though they are originally research-oriented agencies. The extension methods of Experiment Stations are similar with those of extension agencies. (2) The more systematic the characteristic of extension service type is, the higher level of interaction is generated with several exceptions which should not be ignored. This study accentuates the efforts to improve the level of interaction as well as to construct a system as a linked set of actors.

이 연구는 산지를 이용한 산지경관 파편화 모니터링을 제안하고 실효성을 검토하여 다음의 결과를 도출하였다. 첫째, 산지경관이 최근 9년간 빠르게 파편화되고 있어서 국가적 모니터링과 관리가 시급하다. 둘째, 산지경관(GIS) 기반의 평면적 파편화 조사만으로는 중요한 생태적 변화를 확인할 수 없으므로 다양한 조사체계와의 연계가 필요하다. 셋째, 산지경관 파편화 모니터링을 환경영향평가 재해영향평가 등과 연계하여 사전예방원칙을 제도화해야 한다.

This study is about a case of web application development using representative commercial BIM platform-linked APIs from Autodesk and Bentley Systems. The development method was aimed at application development using Autodesk's Forge API and Bentley System's iTwin API. The specific development content was limited to the Model Viewer, Issues, and File Transfer API, and the administrator's site. The first research result is that parts with different internal configurations of commercial platforms were independently modularized and developed, and the common front-end was unified. The second research result is that a web front-end technology, was used to visualize 3D models using the viewer API, and the possibility of additional application expansion was discovered.

Recent automakers are trying to be more precise with the dimension check and moving parts to guarantee high quality and satisfy customer requirements. The aim of this paper is to investigate the design tolerance suitability of door operating mechanism linked arms, lever, and cam-shaft in a mobile air handling unit. These parts are complicated because doors, arms, lever and cam-shaft are connected nonlinearly in 3D. The current tolerance analysis method poses problems in design analysis because the moving doors are reasonably suitable for the AHU function. The 3-DCS analysis method provided useful results not only in establishing the inspection criteria for the quality control of products but also in enabling economical production. As a result, the vent door had $1.62^{\circ}{\sim}1.72^{\circ}$ and the defrost door had $0.84^{\circ}{\sim}0.9^{\circ}$ for the directly connected arms operating-type. For the lever connected arm operating-type, the foot door had $2.0^{\circ}{\sim}2.24^{\circ}$ tolerance, while the tolerance values satisfied the air flow volume distribution rate criteria in the AHU. Finally, the results have confirmed the design's tolerance suitability by using 3-DCS analysis at the early design stages. Reliability can be achieved by analyzing accumulated tolerance during the sub-parts assembly process and the moving mechanism linked especially by arms, lever, and cam-shaft.

Estuary reservoirs were artificial reservoir with seawalls built at the exit points of rivers. Although many water resources can be saved, it is difficult to manage due to the large influx of pollutants. To manage this, it is necessary to analyze watersheds and reservoirs through accurate modeling. Therefore, in this study, we linked the Hydrological Simulation Program-FORTRAN (HSPF), Environmental Fluid Dynamics Code (EFDC), and Water quality Analysis Simulation Program (WASP) models to simulate the hydrology and water quality of the watershed and the water level and quality of estuary lakes. As a result of applying the linked model in stream, R² 0.7 or more was satisfied for the watershed runoff except for one point. In addition, the water quality satisfies all within 15% of PBIAS. In reservoir, R² 0.72 was satisfied for water level and the water quality was within 15% of T-N and T-P. Through the modeling system, We applied upstream pollutant management scenarios to analyze changes in water quality in estuary reservoirs. Three pollution source management were applied as scenarios, the improvement of effluent water quality from the sewage treatment plant and the livestock waste treatment plant was effective in improving the quality of the reservoir water, while the artificial wetland had little effect. Water quality improvement was confirmed as a measure against upstream pollutants, but it was insufficient to achieve agricultural water quality, so additional reservoir management is required.
