An increase in damage to crops and facilities caused by wildlife such as wild boar causes serious social and economic problems to the rural economy in Korea. This study aims to estimate the economic losses incurred to rural households in mountain villages near protected areas in Korea due to the damage to agricultural and forestry production by wildlife. The case of mountain villages located in Toji-myeon, Gurye-gun near the Jirisan National Park was studied as an example. Data were collected by interviewing 84 households across six mountain villages in April and June 2016. The results indicate that the economic losses due to wildlife damage in 2015 were estimated to be 1.65 million KRW per household, which is a total of 138.63 million KRW for the 84 households. Among local products, the most damaged products were chestnut, fern-brake, wild pear, peach, and potato, whereas the most damaged products per production area were sweet potato, peach, corn, and potato. The potential economic losses caused by wildlife damage to agricultural and forestry production in whole Gurye-gun area was estimated to be around 4.0 billion KRW in 2015. However, the municipal government budget for the compensation of wildlife damage was only 0.9 percent of the potential rural economic losses caused by wildlife damage in 2015. The results of our study suggest that the compensation scheme for wildlife damage is inadequate in the respect of social justice. Considering the low financial capacity of the municipalities in mountain areas, the central government should take a progressive responsibility by allocating more financial resources for compensation of economic losses of rural households due to wildlife damage. The equitable and effective governance of wildlife conservation is required for sustainable development of rural communities near protected areas.

Every year, the number of wild animals appearing in human settlements increases, resulting in increased damage to property and human life. In particular, the damage is more severe when wild animals appear on highways or farmhouses. To solve this problem, ecological pathways and guide fences are being installed on highways. In addition, in order to solve the problem in farms, horn repelling using sensors, installing a net, and repelling by smell of excrement are being used. However, these methods are expensive and their effectiveness is not high. In this paper, we used YOLO (You Only Look Once), an AI-based image analysis method, to analyze harmful animals in real time to reduce malfunctions, and high-brightness LEDs and ultrasonic frequency speakers were used as extermination devices. The speaker outputs an audible frequency that only animals can hear, increasing the efficiency to only exterminate wild animals. The proposed system is designed using a general-purpose board so that it can be installed economically, and the detection performance is higher than that of the devices using the existing sensor.

Crop loss and damage by wildlife are becoming more serious to residents inside and around National Parks of Korea annually. It could be caused by small size of Parks, which is couples of ten $km^2$ only, and more than a third of total parks' areas are belonging to privates. Wild boar (Sus scrofa) is one of the most harmful pests in nationwide. Treading down crop field using as bedding or resting site are major damaged types and foraging behavior is following. Besides of boars, Korean water deer (Hydropotes inermis), racoon dog (Nyctereutes procyonoides), and badger (Meles meles) are another serious pests. Mainly, farm products planted in upland, such as corns, sweet potatoes, cabbages, etc. are harmed easily, a rate reaches up to 76.9% of whole losses. 92.4% (n=187) of interviewees, who are mostly seniors, cultivate small crop fields smaller than 1 ha. Crop damage would be started from June to late November, time differences are happened due to latitude, climate condition, and crop differences of National Parks. Dusting animal repellents are easier and widespread methods to prevent animal foraging to crop fields and installing noisy makers using gun powder and setting up scarecrows are traditional methods for repelling animals. Nevertheless, effects of these self-defence are turned out to be useful soon after labors done only. Since legal compensation for crop damages by wildlife are not prepared systematically so far, crop loss are rarely reported to local government by most farmers. Systematic and objective methods for quantifying of crop loss by wildlife and population managements system should be offered urgently to well-managed animals habitat and residents' living inside National Parks.

The damage to farms due to wild animals such as wild boars and elks increases every year, but, in the current system, the catchers from government hunt animals by using guns at night as making an effort to detect wild animals personally by using flashlights. This is very time-inefficient and immediate follow-up action on being damaged is not possible. In this paper, we introduce a system which can detect and recognize the wild animals or the people with high accuracy using thermal imaging camera and infrared camera in company with deep learning technology, so that could kick out or catch the wild animals more quickly than current system.

Recently, a number of local governments as well as private organizations have spearheaded the release of animals into the natural ecosystem in Korea. In 2002, most of these animals released were mammals and birds, but the parameter was gradually expanded to include fish, amphibians, and invertebrates in addition to mammals and birds in 2007, with an increased overall number of animals released. Such increase has not only posed ecological, economic, and public health risks, but also yielded an increase in damages incurred by releasing animals historically or ecologically alien to a given region without thorough risk assessment. The most significant cause of such risks was a critical lack of risk management and regulatory schemes addressing the release of animals into the natural ecosystem. In stark contrast, developed countries long before established the requisite risk management and regulatory schemes either by complying with the IUCN/SSC's Guidelines for Re-Introductions or devising them independently. In this context, the current study has examined the release of animals into the natural ecosystem in Korea and, based on the investigation, asserted a strong need for proper risk management. Moreover, the study has presented systematic risk management and regulatory schemes suitable for the Korean milieu based on a comparative analysis of those employed in developed countries.

Due to population explosion and develop of the industry, expressways, national roads and railways has been developed a lot. But it increased the disconnection of the ecosystem. The phenomenon of wild animals' habitat simplification has been increased. The damage appeared in succession because of the harmful wild animal. Our country is making efforts relief of some affected farming household's financial compensation. But the affected populations can't sleep at night or they are suffering in their basic life because of this kind of night patrol. This research is based on the study of wild animal's ecosystem and their habits, generate and regenerate supersonic waves and infrasound, prevent wild animal's approach to some extent and stop the approximation effectively, focusing on develop a quadcopter about discrete pulses system.

최근 농작물이나 과수는 멧돼지, 고라니, 꿩 등과 같은 유해동물로부터 피해를 입는 사례가 늘고 있다. 특히 멧돼지는 현재 별다른 천적이 없어 개체수가 급격히 증가하고 산간지역을 넘어 도심지역까지 출몰하고 있어 농가에 큰 근심거리가 된다. 종래에는 농장이나 과수원에 허수아비를 세우거나 목책을 치는 소극적인 수단에서부터, 경계를 따라 전기울타리를 설치하거나 야간점멸 조명 기를 설치하는 등의 적극적인 수단을 강구하였으나, 야생동물들이 이들 대책수단에 적응하게 되면서 큰 효과를 거두지 못하고 있으며 확실한 대책이 없이 피해는 점점 더 늘어만 가고 있는 실정이다. 본 논문에서 제안하는 시스템은 무인로봇을 이용한 유해동물 감시 시스템으로, 특히 유해동물을 감지하고 무인로봇을 유해동물로 이동시켜 소리 또는 물질을 방출하도록 하고 유해동물에 대한 관련정보를 관리자단말 및 유관기관서버로 전송하도록 하는 유해동물 감시 시스템 설계 및 개발 관한 것이다.

The objective of this study aims to explore the situation of damage from wild animals in Korea. Through case study on two villages in Injae, Kangwon province and Cheongyang, Chungnam province. This overview summarises the current issues and trends in wild animals damage through two case studies. We found that there are not only to get economic damage but also not to be able to sleep to protect their farm land from animal invading. We suggest to develop physical and chemical instruments not to access their plants in farmland and to increase central and local government's damage repayments.

동물무늬는 서식지에 따라 야생에서 천적으로부터 살아남을 수 있는 중요한 역할을 한다. 동물무늬의 역할 중 하나인 자연과 야생 환경에서 천적의 눈을 피해 위장하는 기능이 있기 때문인데 본 논문에서는 기존 위장무늬의 개선을 위한 GAN 알고리즘 기반 위장 패턴 생성모델을 제안한다. 이 모델은 단순히 색상만을 사용하여 위장무늬의 윤곽선을 Blur 처리를 해서 사람의 관측을 흐리게 만드는 기존의 모델의 단순함을 보완하여 GAN 알고리즘의 활용기술인 Deep Dream을 활용하여 경사 상승법을 통해 특정 층의 필터 값을 조절하여 원하는 부분에 대한 구분되는 패턴을 생성할 수 있어 색뿐만 아니라 위장의 기능이 있는 동물무늬와 섞어 자연과 야생 환경에서 더욱 동화율이 높아진 위장 패턴을 생성하고자 한다.
