Image-based gender classification and age estimation of human are classic problems in computer vision. Most of researches in this field focus just only one task of either gender classification or age estimation and most of the reported methods for each task focus on accuracy performance and are not computationally light. Thus, running both tasks together simultaneously on low cost mobile or embedded systems with limited cpu processing speed and memory capacity are practically prohibited. In this paper, we propose a novel light-weight gender classification and age estimation method based on ensemble multitasking deep learning with light-weight processing neural network architecture, which processes both gender classification and age estimation simultaneously and in real-time even for embedded systems. Through experiments over various well-known datasets, it is shown that the proposed method performs comparably to the state-of-the-art gender classification and/or age estimation methods with respect to accuracy and runs fast enough (average 14fps) on a Jestson Nano embedded board.

The introduction of tracer gas techniques to ventilation studies in indoor environments provides valuable information that used to be unattainable from conventional testing environments. Data acquisition systems (DASs) containing analogue-to-digital (A/D) converters are usually used to function the key role that records signals to storage in digital format. In the testing process, there exist a number of components in the measuring equipment which may produce system-based inference to the monitored results. These unwanted fluctuations may cause significant error in data analysis, especially when non-linear algorithms are involved. In this study, a pre-processor is developed and applied to separate the unwanted fluctuations (noise or interference) in raw measurements and to reduce the uncertainty in the measurement. Moving average, notch filter, FIR (Finite Impulse Response) filters, and IIR (Infinite Impulse Response) filters are designed and applied to collect the desired information from the raw measurements. Tracer gas concentrations are monitored during leakage and ventilation tests in the model test room. The signal analysis functions are introduced to carry out the digital signal processing (DSP) work. Overall the FIR filters process the $CO_2$ measurement properly for ventilation rate and mean age of air calculations. It is found that, the Kaiser filter was the most applicable digital filter for pre-processing the tracer gas measurements. Although the IIR filters help to reduce the random noise in the data, they cause considerable changes to the filtered data, which is not desirable.

Development of digital technology has become closely connected with housing environment. Especially for the matured population, it is very important because they need substantial support in their daily lives. Therefore, the purpose of this paper is to identify needs of digital network services for future housing development. Previous researches were limited to digital technology of network systems and its usages. On the other hand, this study focuses on not only the technology but services. This study consists of literatures review and empirical survey. The subjects were the mid-age and pre-elderly between 45 to 65. The analysis of this study results outlined as follows: First, the pre-elderly appeared to have, in general, positive perceptions about digital services of the housing environment. The results of needs for each space's, showed strongly in basic safety and aiding system for memories. Second, there are differences in needs according to respondent's characteristics such as sex, income, job, house type, experience in digital system. Third, there are differences between what they think and what they really responded in both spaces and services. It menas that present planning elements may not attractive and suitable to residents. Therefore it is necessary to redesign the services. In the future, the most important thing is, making comfortable space not convenient space. That is, excluding unnecessary elements and pick up the right ones for resident's real demands.
