India is a developing nation and has come with comprehensive way in modernizing its reducing poverty, economy and rising living standards for an outsized fragment of its residents. The STEM (Science, Technology, Engineering, and Mathematics) education plays an important role in it. STEM is an educational curriculum that emphasis on the subjects of "science, technology, engineering, and mathematics". In traditional education scenario, these subjects are taught independently, but according to the educational philosophy of STEM that teaches these subjects together in project-based lessons. STEM helps the students in his holistic development. Youth unemployment is the biggest concern due to lack of adequate skills. There is a huge skill gap behind jobless engineers and the question arises how we can prepare engineers for a better tomorrow? Now a day's Industry 4.0 is a new fourth industrial revolution which is an intelligent networking of machines and processes for industry through ICT. It is based upon the usage of cyber-physical systems and Internet of Things (IoT). Industrial revolution does not influence only production but also educational system as well. IoT in academics is a new revolution to the Internet technology, which introduced "Smartness" in the entire IT infrastructure. To improve socio-economic status of the India students must equipped with 21st century digital skills and Universities, colleges must provide individual learning kits to their students which can help them in enhancing their productivity and learning outcomes. The major goal of this paper is to present a low cost, effective learning mechanism for STEM implementation using Raspberry Pi 3+ model (Single board computer) and Node Red open source visual programming tool which is developed by IBM for wiring hardware devices together. These tools are broadly used to provide hands on experience on IoT fundamentals during teaching and learning. This paper elaborates the appropriateness and the practicality of these concepts via an example by implementing a user interface (UI) and Dashboard in Node-RED where dashboard palette is used for demonstration with switch, slider, gauge and Raspberry pi palette is used to connect with GPIO pins present on Raspberry pi board. An LED light is connected with a GPIO pin as an output pin. In this experiment, it is shown that the Node-Red dashboard is accessing on Raspberry pi and via Smartphone as well. In the final step results are shown in an elaborate manner. Conversely, inadequate Programming skills in students are the biggest challenge because without good programming skills there would be no pioneers in engineering, robotics and other areas. Coding plays an important role to increase the level of knowledge on a wide scale and to encourage the interest of students in coding. Today Python language which is Open source and most demanding languages in the industry in order to know data science and algorithms, understanding computer science would not be possible without science, technology, engineering and math. In this paper a small experiment is also done with an LED light via writing source code in python. These tiny experiments are really helpful to encourage the students and give play way to learn these advance technologies. The cost estimation is presented in tabular form for per learning kit provided to the students for Hands on experiments. Some Popular In addition, some Open source tools for experimenting with IoT Technology are described. Students can enrich their knowledge by doing lots of experiments with these freely available software's and this low cost hardware in labs or learning kits provided to them.

The purpose of this study was to find common characteristics in everyday landscape cognition that the residents share and to restore the resulting characteristics through citizen-participatory town design. Through the residents participatory workshop supported by the Gwangju Buk-gu District Autonomy and Citizen Academy of Gwangju YMCA, 304 people from eight administrative districts participated in three programs. In each program, photographed landscape images representing everyday conditions of the townscape were presented in several ways: in program 1, the residents' mental map was studied; in program 2, landscape images of real places were matched to locations on a map; and in program 3, the landscapes were scored on a scale from 1 to 5 according to five descriptive categories. The elements that were recognized as common landscape features were public facilities, pedestrian spaces, school areas, and parks and natural green spaces. Additional results including recognition of the participants affection for the village and a common landscape image shared by the people, as inhabitants looked around at the space of their own lives. It seems possible that more creative townscapes can be created by residents through participatory programs.

Two hundred and sixty-six mothers with preschool and primary school children filled out TV diaries for three days around the TV turning-off campaign day initiated by YMCA. TV diaries were designed to record the TV programs watched by family members as well as the focused child's activities every 15 min. 121 families participated in the campaign voluntarily and 145 families served as the control group. The campaign group watched less than the control group even before the campaign day and differed in several family backgrounds primarily due to the difference of family members' ages in both groups. Despite participating in the campaign, 53.9％ of the families among the campaign group watched TV and 35.5％ of the children in these families watched TV on the campaign day. TV watching time measured by the questionnaire was significantly higher than the estimates by diary method. Participating children in the campaign increased in activities such as reading, indoor play, as well as video watching. In the campaign group, TV watching time on the next day of the campaign increased slightly than the day before it. Preschool and primary school children's activities as well as the watched TV programs were analyzed separately for two groups. In addition, total TV on-time and coviewing patterns by the focused child with the family members were analyzed in relation to the child's other TV watching patterns as well as their related variables.

Background and Purpose : Recently oriental medicine is making a new try for arthritis therapy, one of them is herbal acupuncture. Herbal acupuncture is therapy which combines acupuncture with herbal medicine. Also, aquatherapy will be the good method for arthritis therapy. Aquatherapy begins with YMCA aquatic exercise program in 1984 by America athritis foundation. Aquatherapy uses buoyancy, hydmstatic pressure, resistance, water temperature which is four water characters. So we should study on the herbal acpuncture and aquatherapy. Objecitve and Method : This study researched 21 thesises for herbal acupuncture and many artcles and data for aquatherapy. 21 thesises for herbal acpuncture is divided two groups. One group is about effect on alleviation of pain(18 thesises), the other group is for antiphlogistic effect(13 thesises). About aquatherapy, we research many books, papers, and aquatherpy method, for example Ai Chi, BACKHAB, Watsu. Result and Conclusions : About herbal acupuncture, we researched 21 thesises, and 17 thesises proved the effect on alleviation of pain, 13 thesises proved the antiphlogistic effect of herbal acupuncture. For the aquatherapy, we researched many datas, and concluded like this. Due to the lessned effect of gravity, patients in exercising in water will have very little body weight and very little impact. So, aquatherapy or aquaexercise is an excellent exercise medium for the people who are experiencing some physical difficulty.
