  • Recently farming succession has become an important topic in agriculture in order to secure agricultural manpower in response to the aging of farming households and declining population. This study investigates farmers and agricultural college students' perception of farming succession in Korea, especially of farming succession to a third party. Farmers and agricultural college students are potential farming transferors and successors, respectively. We surveyed 146 farmers and 95 students who graduated or were studying at the Korea National College of Agriculture and Fisheries. The questions of the survey are largely divided into four categories: 1) the will and scope of farming transfer and succession, 2) the requirements for the successors of farming, 3) the perception on the succession to third-parties, and 4) the farming succession policy. According to the survey results 41.4% of farmers and 46.3% of potential farming successors have willingness to accept a farming succession to a third party. When farming succession was carried out through the Farming Succession Exchange, 46.8% of farmers and 54.7% of successors said they are willing to carry out third-party farming succession. This means that a third-party farming succession could be activated if the reliability issue that may arise during the farming succession is resolved through the Farming Succession Exchange. Other implications for farming succession are suggested at the end of this study.

  • As the quality of life has improved today, there is a growing desire among consumers for new space and interest in spending their valuable time in 'the third space' has tended to increase. Cafes have been integrated with sales and exhibition space as the representative third space. For example, it's cafe type automobile exhibition centers. The purpose of this study is to examine the characteristics of 'the third space' in cafe type automobile exhibition centers and suggest a plan for effective spatial characteristics. It checked the necessity of the third space' in automobile exhibition centers by analyzing automobile consumption trends of the 21st century according to industry change and restructures a checklist by grasping cafe type automobile exhibition centers and the concept and characteristics of 'the third space' based on the precedent studies. A questionnaire is made through the checklist drawn and a survey is conducted targeting users of the target areas of cases. The target areas of cases are 4 cafe type automobile exhibition centers opened in Korea since 2014. The analytical results of the target areas of cases that reflected the characteristics of 'the third space' are as follow: First, cafe type automobile exhibition centers must be built to make customers enter the space and at the same time, receive information on automobiles and space naturally. Second, in order to increase satisfaction with the space and brands, there is the necessity to arouse their interest through various experiences including test driving cars directly. Third, revisit intention can be found to be more influenced by spatial design than brand satisfaction. Fourth, partitions or interior for dividing the space need to be improved. In the next studies, specific research on plans about creating design to improve corporate image and brands and induce customers to revisit cafe type automobile exhibition centers by applying the characteristics of 'the third place' to them is required.

  • 본 논문에서는 모노폴 안테나의 각 모드별 전계 분포를 분석하여 전류가 상대적으로 약한 부분(전계가 강한 부분)에 스터브를 이용해 기본 공진 모드에는 영향을 주지 않으면서 안테나의 하모닉 성분인 3차 모드 공진 주파수를 효율적으로 제어하고, 스터브의 두께를 조절하여 임피던스 특성을 조절할 수 있는 방법을 제안한다. 이 방법을 이용하여 일반적인 USB Dongle 크기($20{\times}45mm$)에 안테나를 설계하였으며, -10 dB 기준 2 GHz 대역에서 대역폭이 600 MHz(2.3~3 GHz), 5 GHz 대역의 대역폭은 1 GHz(4.9~5.9 GHz)로 WLAN 주파수 대역을 만족하는 성능과 50 % 효율이 달성되었다.

  • This article will analyze and forecast important variables and dynamics in global power politics after the war in Ukraine. It tries to use several perspectives to analyze international relations, particularly liberal internationalism and structural realism. In short, core variables are as follows; First, how is the US-led liberal international order and globalization being adjusted? Second, how will the U.S.-China strategic competition, which is the biggest and structural variable, cause changes in the international order in the future? The third variable, how stable are Sino-Russia relations in the context of a structuring U.S.-China-Russia strategic new triangle? Fourth, to what extent will third middle hedging states outside the U.S. and China be able to exercise strategic autonomy in the face of multipolarization? To summarize, the first of these four variables is the largest basic variable at the global political and economic level in terms of its impact on the international community, and it has been led by the United States. The second variable, in terms of actors, seems to be the most influential structural variable in global competition, and the US-China strategic competition is likely to be a long game. Thus the world will not be able to escape the influence of the competition between the two global powers. For South Korea, this second variable is probably the biggest external variable and dilemma. The third variable, the stability of Sino-Russia relations, determines balance of global power in the 21st century. The U.S.-China-Russia strategic new triangle, as seen in the current war in Ukraine, will operate as the greatest power variable in not only global power competition but also changes in the international order. Just as the U.S. is eager for a Sino-Russia fragmentation strategy, such as a Tito-style wedge policy to manage balance of power in the early years of the Cold War, it needs a reverse Kissinger strategy to reset the U.S.-Russia relationship, in order to push for a Sino-Russia splitting in the 21st century. But with the war in Ukraine, it seems that this fragmentation strategy has already been broken. In the context of Northeast Asia, whether or not the stability of Sino-Russia relations depends not only on the United States, but also on the Korean Peninsula. Finally, the fourth variable is a dependent variable that emerged as a result of the interaction of the above three variables, but simultaneously it remains to be seen that this variable is likely to act as the most dynamic and independent variable that can promote multilateralism, multipolarization, and pan-regionalism of the global international community in the future. Taking into account these four variables together, we can make an outlook on the change in the international order.

  • 본 논문에서는 3차 전단변형이론이 고려된 비국소 탄성 이론을 이용한 나노 판의 휨 및 진동에 대하여 연구하였다. 비국소 탄성 이론은 미소 규모 효과를 고려할 수 있고 3차원 전단변형이론은 나노 판의 두께방향으로의 전단 변형률과 전단응력의 곡선변화 효과를 고려할 수 있다. 이러한 두 가지 이론을 이용하여 나노 판의 처짐과 고유진동수에 미치는 비국소 이론의 효과를 제시하였다. 국소 탄성이론과의 관계를 수치해석 결과를 통하여 고찰하였다. 또한 (i) 비국소 계수, (ii) 나노 판의 적층형태, (iii) 나노 판의 보강 방향 그리고 (iv) 나노 판의 적층 수 등이 나노 판의 무차원 처짐에 미치는 효과에 대하여 관찰하였다. 본 연구의 결과를 검증하기 위해 참고문헌의 결과들과 비교 분석하였으며 해석결과는 참고문헌의 결과들과 잘 일치함을 알 수 있었다. 비국소 이론에 의한 나노 판의 처짐에 관한 연구는 향후 관련연구에 비교자료로 활용될 수 있을 것이다.
