  • Recently drones have become popular enough to be one of the hobby. The drone refers to an unmanned aerial vehicle which can fly and be steered by a radio wave without a pilot and it has a airplane or helicopter shape. The drone was first started to be used from military purpose, but its usage has been expanded to the private such as construction site, crop-dusting, field discovery, freight shipping and drones to prevent cheating. However the drone that we can see often in the market is expansive, hard to be repaired when it broken down and has a discomfort of the short flight time. In this paper, to solve an uncomfortable talk on the cheap 8-bits microcontrollers ATmega128 Using drone for implementation. Axes gyroscope and accelerometers mcu between posture an attitude control, communications through drone control, pid. Receiver input them into transmitter signals of movements to control drone c the programming was implemented in on the basis of language. drone using ATmega128 microcontroller is possible hovering, By utilizing a pin that are not required for control it can be used as a drone for a variety of uses.

  • 기후변화로 인하여 발생하는 자연재해는 수많은 인명 및 재산 피해를 일으키며, 그 중에서도 가뭄은 물과 식량의 안보를 위협하고 있다. 이에 OECD(2015)는 미래의 세계 인구 40%가 2050년까지 물이 부족한 강 유역에서 살 것이라 예측하고 있으며, 물의 다층적 거버넌스를 개발하여 물을 효과적으로 사용하기 위한 상향식 의사결정, 통합물관리 체제의 개념을 제시하기도 하였다. 우리나라 역시 가뭄으로 인한 피해발생이 빈번하고, 그 강도나 범위가 점차 증가하는 추세이다. 하지만 2000년부터 한국농어촌공사(출범은 '농업기반공사')가 농업용수를 관리해오고 있으며, 농업용 수리시설의 증축, 관리 등이 공적인 관리쳬계로 변화해오면서 자연스럽게 농업인의 물관리는 배제되었다. 또한, 농업용수는 무상·무제한 공공재라는 인식과 농업인 평균 연령이 높아짐에 따라 농업인의 물꼬관리 및 수로 훼손, 무단취수 행위 등에 대한 제제가 불가능한 실정이다. 본 연구에서 최근 농식품부의 「2019년 정부가뭄종합대책」에 포함되어 있는 물절약 거버넌스 구축 및 운영 내용을 바탕으로 농업용수 관리 및 사용구조를 고려하여 두 개 지역의 농어촌공사(여주이천지사, 경주지사) 주도 하에 거버넌스를 간담회 형식으로 운영하였다. 농업용수 물절약 거번넌스 이해관계자들은 각 지역별 공기업, 공무원, 농업인, 언론인, 학계 전문가 등이 참가하였으며, 거버넌스 운영 2회 및 설문조사를 실시하였다. 그 결과 각 이해관계자들은 농업용수 절약을 위한 현재 문제점 및 해결방안 등에 대한 의견을 제시하였으며, 설문조사를 통하여 농어촌공사의 신뢰도 및 중요도가 가장 높고, 높은 중요도에 비하여 농업인 및 지자체 등은 신뢰도가 낮은 것을 확인 할 수 있었다. 이러한 결과는 농업인이 농업용수에 대한 주인의식을 가지고, 적극적이고 자발적인 참여가 필요하다는 것을 보여주고 있으며, 본 연구를 통하여 이루어진 간담회 형식의 거버넌스보다 운영효과 및 지속성을 유지할 수 있는 형태의 거버넌스가 연구되어야한다. 향후 농촌형물 거버넌스 모형이 개발되기 위하여 본 연구는 기초자료로 활용할 수 있다.

  • Currently, as demand for cars at home and abroad increases, the number of vehicles is decreasing and the number of vehicles is increasing. This is the main cause of the traffic jam. To solve this problem, it operates a high-ocompancy vehicle (HOV) lane, a multi-passenger vehicle, but many people ignore the conditions of use and use it illegally. Since the police visually judge and crack down on such illegal activities, the accuracy of the crackdown is low and inefficient. In this paper, we propose a system design that enables more efficient detection using imaging techniques using computer vision to solve such problems. By improving the existing vehicle detection method that was studied, the trigger was set in the image so that the detection object can be selected and the image analysis can be conducted intensively on the target. Using the YOLO model, a deep learning object recognition model, we propose a method to utilize the shift amount of the center point rather than judging by the bounding box in the image to obtain real-time object detection and accurate signals.

  • The purpose of the current research is to reconstruct the process in which changes in elderly support take place from the perspective of the elderly in rural areas. Six elderly couples were interviewed three times with the use of Schütze's 'autobiographical-narrative interview'. The entire interviews consisted of 17 sessions. Interviewed data was analyzed, following the method of Schütze's 'autobiographical-narrative interview analysis'. Research findings were as follows: Elderly support as experienced by the current elderly couples is mainly 'family support', which turned out to be 'dual structural shift' in the process of modernization. That is, there has been an 'internal structural shift' from 'family support on intergenerational, mutual support dimension' to 'family support on intragenerational self-support dimension' on the one hand. An 'external structural shift' has been noticed that realizes the 'socialization of family support' on the other hand. Additionally, a 'discrepancy' was captured between support norm and support behavior as occurred in the process of 'dual structural shift'. Perception on the 'dual structural shift' has proven 'ambivalent'. On the basis of these results, a critical discussion of modernization theory ensued, along with some implications for practice.

  • Gut, Korean shamanist performance, is the archetype of Korean art therapy. It is because gut has the archetype of Korean mind and expresses the archetype in an artistic and therapeutic way. This paper compares and analyzes Gunung-geori of Hwanhaedo-gut and art therapy theories from two perspectives: the range of therapy and the therapeutic principles of performing ways. Gunung-geori aims to solve prolonged conflicts within a family, linking individual problems to family relationship. Such a therapeutic effect of Gunung-geori is well explained through the theory of Bowen's Family Therapy. Also the therapeutic principles that Gunung-geori's performing way are closely related to "transference" of Freud and "putting in the role" in drama therapy.

  • Thyroid radiology practice is a medical practice in which thyroid diseases are diagnosed using imaging modality and treated by imaging-based interventional techniques, and the primary care target is thyroid nodular disease. Diagnosis of thyroid nodules is primarily done by ultrasound imaging and biopsy; thyroid nodules can be treated by non-surgical interventional treatment and thyroidectomy. Ethanol ablation is the first-line treatment for cystic benign nodules, and radiofrequency ablation is used for the treatment of benign solid nodules and recurrent thyroid cancers. Thyroid radiology practice has an essential clinical role in diagnosis and nonsurgical treatment of thyroid nodular diseases, and treatment should be performed based on standard care guidelines for proper patient care. In order to provide the best care to patients with thyroid nodular disease, it is desirable to treat patients in the radiology outpatient clinic. Thyroid radiology practice centered on outpatient clinic practice needs to be expanded.

  • Despite many changes occurring in the objects and methods of reading, the importance of reading as the most effective means of developing human intellectual ability is consistently emphasized. However, in Korea, reading tends to be perceived as a part of tedious and rigid education or learning activities rather than an act of giving pleasure and joy while accompanied by fun and interest. In addition, compared to the high interest and emphasis on reading, discussions on reading programs to systematically implement them are relatively insufficient, and it is difficult to find a study in Korea that grasp the overall research trend in the field of reading programs. Accordingly, in order to generally examine research trends in the field of domestic reading programs, an intellectual structure analysis method based on keyword profiling was applied. In particular, basic analysis, keyword analysis, research area analysis, and analysis by period and year were performed in stages based on the keywords of theses and academic journal articles in the domestic reading program field retrieved from the RISS database. In addition, future research tasks were presented by comprehensively reviewing the research trends of domestic reading programs identified as a result of this intellectual structure analysis.

  • Peak cooling load of large buildings is generally greater than their peak heating load. Internal and solar heat gains are used fur selection of adquate equipment in large building in cold winter climate like Canada and even Korea. The cost of geothermal heat exchanger to meet the cooling loads can increase the initial cost of ground source heat pump system to the extend less costly conventional system often chosen. Thermal ice storage system has been used for many years in Korea to reduce chiller capacity and shift Peak electrical time and demand. A distribution system designed to take advantage of heat extracted from the ice, and use of geothermal loop (geothermal heat exchanger) to heat as an alternate heat source and sink is well known to provide many benifits. The use of thermal energy storage (TES) reduces the heat pump capacity and peak cooling load needed in large building by as much as 40 to $60\%$ with less mechanical equipment and less space for mechanical room. Additionally TES can reduce the size and cost of the geothermal loop by 1/3 to 1/4 compared to ground coupled heat pump system that is designed to meet the peak heating and cooling load and also can eliminate difficuties of geothermal loop installation such as space requirements and thermal conditions of soil and rock at the urban area.

  • This study was conducted to investigate the status of pregnancy and delivery and relationship among knowledge, attitude and practice about pregnancy and delivery in poor country, Nepal. A questionnaire survey by interviewer was conducted to examine the general characteristics, knowledge about pregnancy and delivery, attitude about pregnancy and delivery, the rate of prenatal care and delivery condition of women who had an experience of delivery during last year$(1994.4.13\sim1995.4.12)$ at a rural area, nepal(Dolakha Bazar Area). The major findings are as follows ; Among respondents, 87.5 percentage never had health education and the degree of knowledge about pregnancy and delivery was low. Among respondents, 56.6 percentage had the attitude that they didn't want antenatal care, 42.8 % of respondents answered that they wouldn't visit hospital or health center when vaginal bleeding occurred and 82.9% thought that the delivery itself was dirty. The proportion of women who experienced antenatal care was 28.3%, the proportion of health facilities delivery was 5.3%, which was very low and 82.6% of home delivery case didn't sanitate the tool to cut the umbilical cord. The women who had positive attitude about antenatal care and health facility utilization experienced more antenatal care and health facilities delivery. On consideration of above findings, health education for pregnancy and delivery is required to improve mother-child health status in poor country. To make efficient health education, the target population group, such as the uneducated, inhabitants far from health center or medical facility, must be chosen. To help the poor countries in medical field, the study on health status and its related factors on these countries like this article would be required.
