All the outdoor and indoor spaces are connected with each other. The human being moves toward those spaces with temperature fluctuation between the natural and artificial temperature. We conducted an experiment which subjects were wearing the data logger in urban life, and measured 24 hours' exposed temperature and thermal comfort in summer. Results were as follows. 1. Subjects controls their micro climate like this. Most of them(84.6%) get weather information. Fashion(46.2%) and weather(30.8%) are the reasons to select clothes. They spend their time in indoor environment for 84.92% hours of a day and have an air-conditioner(61.5%) in their houses. 2. Temperature fluctuation which subjects were exposed for 24 hours were from 15.6$^{\circ}C$ to 33.8$^{\circ}C$ and average fluctuation was 9.02$^{\circ}C$. The median value of experienced temperature were 26-26.5$^{\circ}C$ and average temperature was 26.18$^{\circ}C$. They experienced cold shock of 3.96 times in a day.

The purposes of the study were twofold: to investigate the stereotype of position and direction that the users expect when operating the handles of a water faucet in different directions, and to collect information about user’s preferred directions. Six hundred subjects, aged from teens to over sixties, participated in the experiment with the procedure of showing them actual water faucets of a lever-type handle and two round-shaped handles mounted on the sink(horizontal plane) and wall(vertical plane). The water faucets presented to the subjects were most widely used devices in our living environment. The results showed that when the handle of the lever-type water faucet was in the 'up' position, 63% of the subjects expected the device was 'open'. When the cold hot separated water faucets were mounted on the horizontal or vertical plane, over 50% of those who answered the 'open' direction of round type handles responded as 'counter clockwise' for a 'hot' water faucet and 'clockwise' for a 'cold' water faucet. In conclusion, this study suggests that water faucet devices be designed and installed in the way that the users expect them to operate.

다양한 빅데이터 기술이 발전함에 따라, 기업의 전략결정에 있어서 과거에는 의사결정자의 직관이나 경험에 의존하는 경향이 있었다면, 현재는 데이터를 활용한 과학적이고 분석적인 접근이 이루어지고 있다. 이에 많은 기업들이 경영정보시스템 중의 하나인 비즈니스 인텔리전스 (Business Intelligence) 시스템의 예측분석 기능을 활용하고 있다. 하지만, 이러한 시스템이 미래의 경영환경 변화를 예측하고 기업의 의사결정을 돕는 조언자 (Advisor)로서 역할을 한다고 가정할 때, 시스템에서 제공하는 분석결과가 의사결정자에게 도움을 주는 조언 (Advice) 의 역할을 하지 못하는 경우가 많은 실정이다. 따라서, 본 연구에서는 미래예측의 문제에 있어 의사결정자가 시스템의 조언을 따르는데 영향을 미치는 요소들과 영향력에 대해 분석하고, 그 결과를 바탕으로 데이터 기반의 의사결정을 보다 적극적으로 지원하는 시스템 환경을 제시하고자 한다. 좀 더 구체적으로는 예측 과정에 대한 자세한 설명이나 근거 제시가 시스템의 예측결과에 대한 의사결정자의 수용정도에 미치는 영향을 연구하였다. 이를 위하여 193명의 실험자를 대상으로 영화의 개봉 주 매출액을 예측하는 업무를 수행하고, 예측에 대한 설명의 길이와 조언자의 유형(사람과 시스템의 조언 비교)뿐 아니라 의사결정자의 개인 특성이 의사결정자의 조언 수용정도에 미치는 영향을 분석하였다. 시스템에서 제공하는 조언 내용인 예측결과와 설명에 대해 의사결정가가 느끼는 유용성, 신뢰성, 만족도가 조언의 수용에 미치는 영향도 분석하였다. 본 연구는 시스템의 분석결과를 조언으로 보고 조언자와 조언에 관한 의사결정학 분야의 선행연구를 접목시켜 경영정보시스템 연구 분야를 확장하였다는 점에서 연구의 의의가 있고, 실무적으로도 데이터 기반의 의사결정을 보다 적극적으로 지원할 수 있는 시스템 환경을 만들기 위해서 고려해야 할 점들을 제시함으로써 시스템 활용을 위한 정책결정에도 도움을 줄 수 있을 것으로 본다.

The purpose of this study is to extract typical body shapes of Korean adults based on the three-dimensional Korean anthropometric data measured through 5th national anthropometric survey and to examine the suitability of the 3-D human shape data for the interior packaging. 36 three-dimensional anthropometric variables related to the design of vehicle interior were considered for the appraisal of typical body shapes. Four major factors were extracted by the factor analysis and factor scores were calculated for all subjects. Typical or standard drivers of Korean adults were selected by the minimum deviation criteria for the four factor scores with respect to 5th, 50th, and 95th percentiles, respectively. Typical drivers of Korean adults were visualized by the CATIA-HUMAN program due to the absence of proper application software for three-dimensionally scanned human body data. There are considerable differences between the anthropometric data of Korean adults and those provided by CATIA-HUMAN program, which shows that the modeling data provided by CATIA-HUMAN should not be directly applied to the ergonomic evaluation for the vehicle design. This suggests the necessity for the development of suitable software for scanned human shape data. It is also expected that the anthropometric data of typical drivers extracted from this study help design package layouts and improve the suitability of ergonomic evaluation for Korean customers.

Through-wall ultra-wide band (UWB) radar has been considered as one of the preferred and non-contact technologies for the targets detection owing to the better time resolution and stronger penetration. The high time resolution is a result of a larger of bandwidth of the employed UWB pulses from the radar system, which is a useful tool to separate multiple targets in complex environment. The article emphasised on human subject localization and detection. Human subject usually can be detected via extracting the weak respiratory signals of human subjects remotely. Meanwhile, the range between the detection object and radar is also acquired from the 2D range-frequency matrix. However, it is a challenging task to extract human respiratory signals owing to the low signal to clutter ratio. To improve the feasibility of human respiratory signals detection, a new method is developed via analysing the standard deviation based kurtosis of the collected pulses, which are modulated by human respiratory movements in slow time. The range between radar and the detection target is estimated using joint time-frequency analysis (JTFA) of the analysed characteristics, which provides a novel preliminary signature for life detection. The breathing rates are obtained using the proposed accumulation method in time and frequency domain, respectively. The proposed method is validated and proved numerically and experimentally.

Vision-based Human Pose Estimation has been considered as one of challenging research subjects due to problems including confounding background clutter, diversity of human appearances and illumination changes in scenes. To tackle these problems, we propose to use a new multi-stage convolution machine for estimating human pose. To provide better heatmap prediction of body joints, the proposed machine repeatedly produces multiple predictions according to stages with receptive field large enough for learning the long-range spatial relationship. And stages are composed of various modules according to their strategic purposes. Pyramid stacking module and dilation module are used to handle problem of human pose at multiple scales. Their multi-scale information from different receptive fields are fused with concatenation, which can catch more contextual information from different features. And spatial and channel information of a given input are converted to gating factors by squeezing the feature maps to a single numeric value based on its importance in order to give each of the network channels different weights. Compared with other ConvNet-based architectures, we demonstrated that our proposed architecture achieved higher accuracy on experiments using standard benchmarks of LSP and MPII pose datasets.

The purpose of this study is to offer basic data on sex education for middle and high school students through content analysis of sex education subjects. The objects of this study were sex related subjects in the 7th grade curriculum and sex education guide books. The results were as follows: According to the results of analyzing sex education topics classified by grade, the 7th grade accounted for 35.2% of total topics, the 8th grade 2.9%, the 9th grade 2.9%, and the 10th grade 32.3%, the result of analyzing sex education topics classified by subject, showed 76.4% of total topics in sex education guide book, 29.4% were technique and domestic subjects, 20.5% were physical subjects, 17.6% were moral subjects, 8.8% were science subjects, 2.9% were society subjects. The domains which were chiefly concerned in sex education curricula for middle school students were "Human Development", "Relationship", and "Sexual Health". On the other hand, the domains which were mainly concerned with sex education curricula for high school students were "Relationship", "Sexual Behavior" and "Sexual Health". Most sex education subjects provided less instruction concerning "Personal Skills" and "Sexual Behavior" than other domains. The suggestion according to the results were as follows: It is desirable to teach sex education as an integrated subject. Especially, sex education should be a part of a comprehensive school health education program. Because this study focused on analyzing materials for teachers, further research is recommended to analyze sex education materials for students.
