The Impact

This work aims to raise awareness of environmental problems through interactive means, which, today, are much more appealing than the traditional ones to the academic community. To better inform community members of the importance of the 3Rs – Reduce, Reuse and Recycle, it was decided to develop an interactive 3D game, accessible through the Word Wide Web. This game includes 3 different activities which can be played in any order: solid waste recycling, saving water, and saving electricity. A small group of people evaluated the games; all participants were familiar with video games. It should be noted that the tests carried out focused only on the usability and interactivity of the game – the impact of the game at the 3Rs level – Reduce, Reuse and Recycle – has not been tested yet. The game makes the user more aware of the physical space where he moves (the school), showing his progress in real time. At the end of the game, the user is presented with the total time he took to finish his tasks and the total score achieved. In this way, the game becomes more interesting to the user.

Raising awareness of energy issues to high school students using traditional teaching methods can be tedious and unproductive. However, letting a high school student engage in an interactive 3D game can not only stimulate general interest but can also captivate and educate. During 2013, several demonstrations were given in a virtual reality lab at the University of Louisiana that explained solar thermal power concepts and other alternative energy technologies. These were given on three 150 inch screens in a concave design, immersing the user in a 3D educational experience. Several software technologies were used in the creation of the game, the main ones being Solidworks, 3ds Max Design, and Unity 3D. The scene of the game was constructed using a scale model of the Cleco Alternative Energy Center in Crowley, Louisiana. This paper gives a literary review of educational games and explains the design process of the interactive 3D game and the educational experience from demonstrations during 2013.

Abstract. To investigate the effect of response alternatives/scoring procedures on the measurement properties of the Center for Epidemiologic Studies Depression Scale (CES-D) which has the four response alternatives, a polytomous item response theory (IRT) model was applied to the responses of 2,061 workers and university students (1,640 males, 421 females). Test information functions derived from the polytomous IRT analyses on the CES-D data with various scoring procedures indicated that: (1) the CES-D with its standard (0-1-2-3) scoring procedure should be useful for screening to detect subjects with “at high-risk” of depression if the θ point showing the highest information corresponds to the cut-off point, because of its extremely higher information; (2) the CES-D with the 0-1-1-2 scoring procedure could cover wider range of depressive severity, suggesting that this scoring procedure might be useful in cases where more exhaustive discrimination in symptomatology is of interest; and (3) the revised version of CES-D with replacing original positive items into negatively revised items outperformed the original version. These findings have never been demonstrated by the classical test theory analyses, and thus the utility of this kind of psychometric testing should be warranted to further investigation for the standard measures of psychological assessment.

Haji merupakan rukun Islam yang kelima yang wajib dilaksanakan oleh seorang muslim yang telah mampu melaksanakannya. Manasik haji pada dasarnya adalah memberikan pelajaran atau informasi mengenai tata cara melaksanakan ibadah haji, sehingga tidak hanya terbatas pada calon jama’ah haji, biasanya masyarakat beragama muslim mempelajari tata cara melaksanakan ibadah haji dengan menggunakan buku-buku atau dengan cara memperagakan langsung dengan cara mensimulasikan tata cara ibadah haji sesuai dengan kondisi yang sebenarnya. Namun banyak kalangan masyarakat muslim yang enggan mendalami manasik haji, dikarenakan beberapa hal seperti tidak adanya waktu, dan kurangnya minat mempelajari dikarenakan kurang menarik dan tidak praktis. Dari hal tersebut sehingga muncul ide untuk membuat aplikasi simulasi manasik haji berbasis virtual 3D, aplikasi ini berisi tentang simulasi untuk rukun haji. Aplikasi manasik haji berbasis virtual reality ini dirancang dan dibuat dengan menggunakan software 3Ds Max dan unity 3D Game Engine. Hasil penelitian berupa aplikasi manasik haji yang dapat menampilkan simulasi virtual reality, yang meliputi simulasi tiba di bandara, Wukuf di Arafah, Mabit di Muzdalifah, Mabit di Mina, Jumrah, Tawaf, Sa’i dan simulasi Tahallul. Dengan adanya aplikasi ini diharapkan akan terjadi peningkatan minat masyarakat dalam mempelajari tata cara pelaksanaan ibadah haji.Kata kunci : virtual reality, manasik haji, simulasi, 3D.

Airborne LiDAR data: relevance of visual interpretation for forestry Airborne LiDAR surveys are particularly well adapted to map, study and manage large forest extents. Products derived from this technology are increasingly used by managers to establish a general diagnosis of the condition of forests. Less common is the use of these products to conduct detailed analyses on small areas; for example creating detailed reference maps like inventories or timber marking to support field operations. In this context, the use of direct visual interpretation is interesting, because it is much easier to implement than automatic algorithms and allows a quick and reliable identification of zonal (e.g. forest edge, deciduous/persistent ratio), structural (stratification) and point (e.g. tree/stem position and height) features. This article examines three important points which determine the relevance of visual interpretation: acquisition parameters, interactive representation and identification of forest characteristics. It is shown that the use of thematic color maps within interactive 3D point cloud and/or cross-sections makes it possible to establish (for all strata) detailed and accurate maps of a parcel at the individual tree scale.
