Noise in residential buildings should be assessed not only in terms of impact on health, safety and performance of inhabitants, but also for the “value” of the building (apartment) in a certain environment. Building energetic certification implementation is one of the first compulsory legislative evaluation criteria. This paper wants to draw the attention to the need for vibro-accoustic building (apartment) certification. Presented tabular evaluation is an objective evaluation. The reason for that are the tendencies related to noise in environment: increased number and levels of noise sources in buildings’ exterior and interior, increasing demands for sound insulation of building structures and growing number of “noise” complaints.

Currently traditional games are rarely played by children along with the times, even though several studies mention that traditional games have a very important role in stimulating the gross motor development that is owned by every child. This research aims to create new game products from traditional sport modifications that are appropriate to be used and can potentially develop the gross motor skills of children aged 9-12 years. The research method used is Research and Development (RD) which is carried out by the steps of: 1) Product Design, 2) Validation Phase 1, 3) Design Revision, 4) Second Stage Validation, 5) Trial of Small Scale Products, 6) Product Revision, 7) Final Product. The research sample was 30 students at Widarapayung Wetan State Elementary School 02 grades IV, V, VI. The research instrument was in the form of a questionnaire containing statements validated by experts, then the scores obtained were processed and converted into product evaluation criteria. The results of this study obtained an assessment of game experts by 94% or the category of "Very Good", education experts by 90% or the category of "Very Good" and experts for growth and development by 82% or the category of "Very Good", as well as an assessment of PJOK teachers by 85% or "Very Good" category, so as to get a final score of 91.2% or "Very Good" category, thus it can be stated that the PPS game is very appropriate to be used as a game model that can potentially develop gross motor skills of children aged 9-12 year.AbstrakSaat ini permainan tradisional mulai jarang dimainkan anak-anak seiring dengan perkembangan zaman, padahal beberapa studi menyebutkan bahwa permainan tradisional memiliki peran yang sangat penting dalam merangsang perkembangan motorik kasar yang dimiliki oleh setiap anak. Penelitian ini bertujuan untuk menciptakan produk permainan baru dari modifikasi olahraga tradisional yang layak digunakan dan berpotensi dapat mengembangkan kemampuan motorik kasar anak usia 9 - 12 tahun. Metode penelitian yang digunakan adalah Research and Development (RD) yang dilakukan dengan langkah-langkah: 1) Desain Produk, 2) Validasi Tahap ke-1, 3) Revisi Desain, 4) Validasi Tahap Kedua, 5) Uji Coba Produk Skala Kecil, 6) Revisi Produk, 7) Produk Akhir. Sampel penelitian adalah 30 siswa SD Negeri Widarapayung Wetan 02 kelas IV, V, VI. Instrumen penelitian berupa angket berisi pernyataan yang di validasi oleh ahli, kemudian skor yang diperoleh diolah dan dikonversikan ke dalam kriteria penilaian produk. Hasil penelitian ini memperoleh penilaian dari ahli permainan sebesar 94% atau kategori “Sangat Baik”, ahli pendidikan sebesar 90% atau kategori “Sangat Baik” dan ahli pertumbuhan dan perkembangan sebesar 82% atau kategori “Sangat Baik”, sert penilaian dari guru PJOK sebesar 85% atau kategori “Sangat Baik”, sehingga memperoleh nilai akhir sebesar 91,2% atau kategori “Sangat Baik”, dengan demikian dapat dinyatakan bahwa permainan PPS sangat layak digunakan sebagai model permainan yang berpotensi dapat mengembangkan kemampuan motorik kasar anak usia 9 – 12 tahun.

The allure of free, industrial-strength software has many enterprises rethinking their open source strategies. However, selecting an appropriate open source software for a given problem or set of requirements is very challenging. The challenges include a lack of generally accepted evaluation criteria and a multitude of eligible open source software projects. The contribution of this work is a set of criteria and a methodology for assessing candidate open source software for fitness of purpose. To test this evaluation model, several important open source projects were examined. The results of this model were compared against the published results of an evaluation performed by the Defense Research and Development Canada agency. The proposed evaluation model relies on publicly accessible data, is easy to perform, and can be incorporated into any open source strategy.

Aerosol samples were collected in Phoenix, Arizona on eleven dates between July 1989 and April 1990. Elemental compositions were determined for approximately 1000 particles per sample using an electron microprobe with an energy-dispersive x-ray spectrometer. Fine-fraction samples (particle cut size of 1 to 2 μm) were analyzed for each date; coarse-fraction samples were also analyzed for four of the dates.The data were reduced using multivariate statistical methods. Cluster analysis was first used to define 35 particle types. 81% of all fine-fraction particles and 84% of the coarse-fraction particles were assigned to these types, which include mineral, metal-rich, sulfur-rich, and salt categories. "Zero-count" particles, consisting entirely of elements lighter than Na, constitute an additional category and dominate the fine fraction, reflecting the importance of anthropogenic air pollutants such as those emitted by motor vehicles. Si- and Ca-rich mineral particles dominate the coarse fraction and are also numerous in the fine fraction.
