  • The government is largely responsible for preventing “the tragedy of the common property”, but fisherman's effort fer an autonomous fishery control is equally required. Especially in these days of EEZ such self- regulated fishery management system should be developed and cared for as well. This study aimed to explore a proper management system for coastal fishing ground that now requires the responsible fisheries management by investigating and analysing more drastically the managerial functions of fishery right by Eochon-Gye(the smallest unit of fisheries cooperative based on a fishing village), a typical fishery producer's organization in Korea. This study also included such contents as (1) an understanding of fishery producer's organization, (2) the utilization and management system of coastal fishing ground, (3) the actual condition of fishing right distribution in Korea, (4) the fishery right management and activity of Eochon-Gye, (5) the operation and distinctive feature of fishery right in Japan, (6) the intervention and limit of fishery producer's organization for fishing ground management function, and (7) summary and proposal. We made all Eochon-Gye of the whole country an object of this study and carried out an investigation into Eochon-Gye through a questionnaire. We extracted 359 Eochon-Gye, 20% of the total 1,719 Eochon-Gye as a random sample and investigated these regions through a questionnaire by mail. The contents of the questions consist of 40 items, including six categories about the organization of eochon-gye, and fishing ground management and activities.

  • Compared to Korea's recently expanding art distribution market, the difficulty of securing the authenticity of art is hindering the healthy development and growth of the market. In this regard, the current situation of the emotional system in the UK and France's art distribution process are examined as excellent cases in foreign countries. In the UK, there is a full autonomous appraisal system by art experts without state intervention. In France, the judiciary and the administration of art have an appraisal system for art works, so the appraisal work has reliability and objectivity. Through the above system, this study suggests measures to strengthen transparency in art trade and to break unfair practices in order to secure the authenticity of the domestic art distribution market. In addition, this study proposes the establishment of a professional appraisal system and the improvement of administrative law regulations to explore the possibility of ensuring fairness through mediation through the example of an international arbitration body.

  • The important goal of the unmanned vehicle technology is on controlling the direction and speed of the vehicle with information acquired from various sensors, without the intervention of the driver, until the vehicle reaches to its destination. In this paper, our focus is on developing an unmanned conveyance system by exploiting low-cost sensing technology for indoor factories or warehouses, where the moving range of the vehicle is limited. To this end, we propose an architecture of a scalable automated conveyance system. Our proposed system includes a number of unmanned conveyance vehicles, and the efficient control mechanism of the vehicles without neither conflicts nor deadlock between the vehicles being simultaneously moved. By implementing the real prototype of the system, we successfully verify the efficiency and functionality of the proposed system.

  • The Bank of Korea raised the benchmark interest rate by a quarter percentage point to 1.75 percent per year, and analysts predict that South Korea's policy rate will reach 2.00 percent by the end of calendar year 2022. Furthermore, because market volatility has been significantly increased by a variety of factors, including rising rates, inflation, and market volatility, many investors have struggled to meet their financial objectives or deliver returns. Banks and financial institutions are attempting to provide Robo-Advisors to manage client portfolios without human intervention in this situation. In this regard, determining the best hyper-parameter combination is becoming increasingly important. This study compares some activation functions of the Deep Deterministic Policy Gradient(DDPG) and Twin-delayed Deep Deterministic Policy Gradient (TD3) Algorithms to choose a sequence of actions that maximizes long-term reward. The DDPG and TD3 outperformed its benchmark index, according to the results. One reason for this is that we need to understand the action probabilities in order to choose an action and receive a reward, which we then compare to the state value to determine an advantage. As interest in machine learning has grown and research into deep reinforcement learning has become more active, finding an optimal hyper-parameter combination for DDPG and TD3 has become increasingly important.

  • As vehicle technology has grown, autonomous driving that does not require driver intervention has developed. Accordingly, CAN security, an network of in-vehicles, has also become important. CAN shows vulnerabilities in hacking attacks, and machine learning-based IDS is introduced to detect these attacks. However, despite its high accuracy, machine learning showed vulnerability against adversarial examples. In this paper, we propose a adversarial CAN frame generation method to avoid IDS by adding noise to feature and proceeding with feature selection and re-packet for physical attack of the vehicle. We check how well the adversarial CAN frame avoids IDS through experiments for each case that adversarial CAN frame generated by all feature modulation, modulation after feature selection, preprocessing after re-packet.

  • The SPES (Selective Production of Exotic Species) facility, currently under development at Legnaro National Laboratories of INFN, aims at the production of intense RIB (Radioactive Ion Beams) employing the Isotope Separation On-Line (ISOL) technique for interdisciplinary research. The radioactive isotopes of interest are produced by the interaction of a multi-foil uranium carbide target with a 40 MeV 200 μA proton beam generated by a cyclotron proton driver. The Target Ion Source (TIS) is the core of the SPES project, here the radioactive nuclei, mainly neutron-rich isotopes, are stopped, extracted, ionized, separated, accelerated and delivered to specific experimental areas. Due to efficiency reasons, the TIS unit needs to be replaced periodically during operation. In this highly radioactive environment, the employment of autonomous systems allows the manipulation, transport, and storage of the TIS unit without the need for human intervention. A dedicated remote handling infrastructure is therefore under development to fulfill the functional and safety requirement of the project. This contribution describes the layout of the SPES target area, where all the remote handling systems operate to grant the smooth operation of the facility avoiding personnel exposure to a high dose rate or contamination issues.

  • This study figured out the influence of parenting attitudes and parenting efficacy on parents educational needs. Accordingly, it is for the purpose of being tried to establish a basic data for educational programs and intervention strategy to promote parenting attitudes and parenting efficacy for marriage immigration women. This is a study on descriptive correlation among 130 marriage immigration women with adolescent children. As the results of this study, parenting attitudes and parenting efficacy showed to be affected on the parents educational needs and had positive correlation(r=.248, p<.01). Receptive parenting attitudes and autonomous ones in the parenting attitudes had also positive correlation(r=.192, p<.05). It showed that the higher the excessive expectant parenting attitudes are, the higher the educational needs of social instruction are, and the higher the receptive parenting attitudes are, the higher the educational needs to understand growth development are. Also it showed that the lower the parenting efficacy is, the higher the social instruction and the educational need on growth for parents themselves are. The parents educational needs were high in the educational needs on learning, career instruction and education of effective communication. Based on the results above, this study hoped to develop structured education program develop for marriage immigration women and have more education opportunities for enhancing receptive parenting attitudes, autonomous ones and parenting efficacy.

  • This study comprised descriptive research into nurses' anger, job stress and social support, and the impact thereof on interpersonal caring behaviors. This study focused on the anger and interpersonal caring behaviors of nurses. From December $1^{st}$ to $31^{st}$ 2014, the data of 174 working at university hospitals in four cities were collected. This study focused on the anger and interpersonal caring behaviors of nurses. Repeated anger rumination reduced interpersonal caring behaviors. The influence of anger-in and anger-control on interpersonal caring behaviors was confirmed. Although the stress score of job demand was too high, an autonomous nursing environment, material support and expansion of the educational period are required to enhance interpersonal caring behaviors. Thus, this study investigated the elements of interpersonal caring behavior necessary for nursing care and suggests the necessity on convergence study of addressing feelings of anger as an emotion management intervention.
