In this paper, we propose a system that can provide a environment for plant cultivation in connection with LED plant factories and enable users to participate in plant cultivation remotely to engage in personal hobbies. The proposed system can monitor the growth conditions of plants through various sensors and remotely adjust the cultivation environment required for plant growth through the Arduino system, so that users can feel the satisfaction of plant cultivation and harvesting as a hobby. On the other hand, we suggest a mutual benefit structure for plant factory and users by securing a certain amount of income source to factory, by paying the idle space to the individual online. This paper demonstrates the feasibility of the proposed system by making the prototype of the remote plant cultivation consignment system using the Arduino and Android application(App.), and contributes to popularize the LED plant factories and expand the business area in future.

Recently, the number of people enjoying various leisure sports has increased. As a result, the vehicles with various items loaded onto the roof can be easily seen on the street. The device that enables loading on the vehicle roof is called by a rack, and each vehicle has its own different shape. There are various types of roof racks but they must have the strength and durability to load heavy loads. In this study, the structural analysis was performed according to the support method of the roof rack and the shape of the fixture. Of three models, it was shown that model C had the best durability. Therefore, this study result shows which shape of the roof rack is most stable among the models. By utilizing the design data about a convergence study through the structural analysis due to the shape of automotive roof rack obtained on the basis of this result, the esthetic feeling can be shown by being converged onto the part of automobile at actual life.

최근 성인들 중에서도 취미로 가지고 노는 장난감 즉 '키덜트 장난감'의 관심도가 증가하는 추세이다. 그 중에서도 높은 매출 상승세를 보이는 RC카와 VR은 지속적으로 시장규모를 성장시키기 위해서 추가적인 콘텐츠가 필요하다고 판단된다. 그러므로 본 프로젝트는 두 아이템을 융합하여 차별적 콘텐츠가 있는 RC카 개발을 목표로 한다. VR기기 영상을 보면서 컨트롤러로 RC카를 조종하는 구성이며, 특징적인 콘텐츠로는 OpenCV 컴퓨터비전 알고리즘을 활용하여, 트랙내의 차선, 표지판 등을 인식하고 안전주행 점수를 평가하는 Score모드가 있다. 결론적으로 RC카와 VR을 동시 활용하는 것이 특징인 본 프로젝트는 높은 H/W 독립성, 확장성을 가지며, S/W적으로는 혼합현실적 요소를 체험할 수 있다. 나아가 사회적인 의미로 여러 세대가 함께하는 유익한 놀이 콘텐츠의 활성화를 기대할 수 있다.

The study was investigate the effect of family stress and job stress on depression in middle man. A questionnaire was completed by 127 C & K city middle aged mans from july 1 to August 20 2018. The data were analyzed by SPSS/WIN 21.0 program, descriptive statistics, ANOVA, t-test, and Pearson correlation coefficient calculation and multiple regression analysis. Differences in family stress job stress depression according to general characteristics of middle-aged men showed significant difference in economic status and old age instability. The variables affecting depression are job stress(${\beta}=0.288$, p<.001), aging anxiety(${\beta}=0.142$, p<.001), economic status(${\beta}=0.035$, p<.001), family stress(${\beta}=0.016$, p<.001). As a way to reduce family stress and job stress, it is necessary to deal with health care and family conflict such as exercise hobby life relaxation.

This study aimed to provide the basic data necessary for lowering the academic and job stress and turnover rate of male dental hygienists in the future, by understanding the academic and job stress factors of male dental hygienists. As the research method, this study conducted the one-to-one interview with five male dental hygienists with career experiences for 1-5 years at dental hospital and dental clinic, and the interview took about an hour. In the results of this study, the main academic stress factors were interpersonal relationship and too much assignment while the main job stress factors were communication problems with female staffs and director, and anxiety about the future. They relieved their stress through meeting with friends, relaxation, and hobbies. Based on such results of this study, it would be necessary to suggest the measures for improving the interpersonal relationship in academic life of male dental hygienists, providing information about employment, and also finding the future-oriented goals and confidence in the profession as a male dental hygienist.

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.

Recently, personal information processing are becoming more important in the behavioral advertising based on online and mobile platform. The behavioral advertising analyzes and utilizes individual's search & purchase history, hobbies, and tendency based on the personal behavior information collected using the automatic collection device. Therefore, it collects and stores other types of personal information which did't defined in Privacy Act and can analyze personal behavior. This characteristics may cause disclosure of personal information and exposure to intrusion. In this paper, we investigate and analyze the privacy policy of the advertising agencies, and discussded the measures to be taken in collecting, storing and using personal information suitable for behavior information.

The baby boomers born between 1955 and 1974, recently called the new age, form a huge population group and show characteristics different from the previous traditional older generations. With the retirement of those who make up 33% of the nation's population in earnest, the emergence of a new generation of the elderly population and policy changes are required. The new middle age generation, also called the opal generation, want to spend their old age productively and autonomously, which has increased due to the increase in life expectancy, and have some economic ability, such as enjoying overseas travel in old age. As preparation for old age is insufficient, policy attention is required for the younger generation as a new generation. In this paper, focusing on the baby boom generation, the definition of the opal generation, their consumption lifestyle, attitudes, social activities, leisure activities, and lifestyle such as health efforts are investigated, and job creation, social re-education, and local It is intended to present practical measures for preparing for old age, such as the establishment of medical facilities and social consideration for a leisurely cultural life.

Economic analysis predicts that the drone market will grow, and the growth of the toy and hobby drone market is expected to gradually expand. Drone expectations are rising due to the net economic function of drone market growth, but accidents due to improper management and operations are also increasing. The difference in toy drone performance is incomparably small compared to industrial drone performance, but the ordinary buyer can not know whether the difference can cause an accident during use. The toy drones used in this study were obtained from KC and CE certification, and 20 kinds of drones were used. The flight time ranged from a minimum of 3 minutes to a maximum of 12 minutes, and the control distance ranged from a minimum of 20m to a maximum of 380m. Therefore, it is necessary to secure product safety through sampling inspection of the radio wave output of toy drones, and it is also necessary to mount an algorithm that automatically lowers the altitude or hover when exceeding the limit flight distance. For future research, we will build data to establish toy drone safety standards through a altitude testing and impact testing of toy drone.
