The Hajong are the ancient tribal forest community among the ethnic minorities of the North-East region of Bangladesh. The study was carried out with respect to three income groups highlighting their indigenous knowledge. A total of forty-five households (fifteen from each income groups) were assessed using different participatory appraisals through semi-structured questionnaires. A special type of indigenous knowledge on food habit was explored in the Hajong community, which correspond to the severe dependence on forest resources. They collect their food resources from homestead forest (45%) followed by forest (40%), market and others. They have indigenous hunting procedure to trap the animal in the forest. Twenty three tree species were tremendously planted in their homestead forests which are the very important source of food. Male are highly responsible to collect the food materials from forest as well as other sources.

An ethno-medical investigation was carried out to understand the use of plants in indigenous health care practice of the Hajong tribe community in North Eastern Bangladesh. The study of ethnobotany relating to any tribe is in itself a very intricate or long-winded process. The present study was done through structured questionnaires in consultations with the tribal practitioners and has resulted in the documentation of 25 plant species belonging to 21 families including herbs (36%), shrubs (32%), trees (28%) and climber (4%) were frequently used by the Hajong tribe for curing 27 ailments. For curing ailments, the use of aboveground plant parts was higher (86.67%) than the underground plant parts (13.33%). Leaf was used in the majority of cases for medicinal preparation (13 species), followed by fruits (7 species), root/rhizome (4 species), whole plant (3 species) and besides these, seed, latex and bark were used one species each, respectively. The study thus underlines the potentials of the ethnobotanical research and the need for the documentation of indigenous healthcare knowledge pertaining to the medicinal plant utilization for the greater benefit of mankind.

IT 기술이 발전함에 따라 로봇은 다양한 부분에서 필요성을 인정받고 있다. 최근 산업용 로봇에만 집중되었던 로봇 시장은 일상생활에서도 사용할 수 있는 가정용 로봇까지 시장이 확대되고 있으며, 실제로 청소로봇이나 방범로봇과 같은 가정용 로봇이 개발되어 판매되고 있는 상태이다. 대부분의 가정용 로봇은 높은 가격에도 불구하고 기능이 제한적이며, 실제 로봇으로서 지능적인 부분은 자동청소 기능과 같이 사용자와의 소통이 없는 단순한 수준이다. 본 논문은 이동형 디바이스와 음성제어 및 각종 서비스를 제공하기 위한 스마트폰이 결합된 형태의 지능적인 가정용 로봇을 제안한다.
