In 2017, the United Nations reported that the population aged 60 and above was increasing more rapidly than all younger age groups worldwide, projecting that by 2050, the population aged 60 and above would constitute at least 25% of the global population, excluding Africa. The world is experiencing a decline in the rate of increase in the working-age population due to global aging, and the younger generation tends to avoid difficult and challenging occupations. Although theoretically, AI equipped with artificial intelligence can replace humans in all fields, in the realm of practical information security, human judgment and expertise are absolutely essential, especially in ethical considerations. Therefore, this paper proposes a method to retrain and reintegrate IT professionals aged 50 and above who are retiring or seeking career transitions, aiming to bring them back into the industry. For this research, surveys were conducted with 21 government/public agencies representing demand and 9 security monitoring companies representing supply. Survey results indicated that both demand (90%) and supply (78%) unanimously agreed on the absolute necessity of such measures. If the results of this research are applied in the field, it could lead to the strategic development of senior information security professionals, laying the foundation for a new market in the Korean information security industry amid the era of low birth rates and longevity.

Three studies re-examined Shafer's(1993) response compatibility hypothesis in decision making. This hypothesis proposes that participants choose or reject an option when its features are compatible with either a selection or a rejection response. By changing the description of options into sentences and by the prior presentation of either a selection or a rejection question, we obtained results fairly consistent with the predictions of the response compatibility hypothesis. Based on the analysis of both previous and present results, we discussed the importance of preference elicitation methods when constructing options. Our results were compared to those of recent studies.

In this present study, the correlation between subjective preference of essential odors and EEG response were investigated quantitatively. EEG signals were measured from 19 electrodes according to the International 10-20 system (Fpl, Fp2, F2/4, F7/8, Fz, C3/4, Cz, P3/4, Pz, T3/4, T5/6, Ol/2) from 8 healthy males subjects in four odor conditions. Four odor conditions (Rose oil bulgarian, Lemon oil misitano, Jasmin abs, Laverder iol france (KIMEX co. Ltd)) were applied for each subject in the experiment. Through the subjective evaluation, the most pleasant odor for each subject was determined. The power spectrum of ${\alpha}$/${\beta}$ of EEG signals from the most pleasant odor was compared with those from the control condition, which has no odor at all. It was observed that the power spectrum of ${\alpha}$/${\beta}$ of EEG from the most pleasant odor was increased significantly on F3, F3, F4,74 comparing to the control condition. This result indicates that the power spectrum of ai${\beta}$ could be a new index for measuring the levels of pleasantness of odors.

In spite of its simple rule, Go is one of the most complex strategic board games in the field of Artificial Intelligence (AI). Monte-Carlo Tree Search (MCTS) is an algorithm with best-first tree search, and has used to implement computer Go. We try to find the most promising first move using MCTS for playing a Go game on a board of size smaller than $9{\times}9$ Go board. The experimental result reveals that MCTS prefers to place the first move at the center in case of odd-sized Go boards, and at the central in case of even-sized Go boards.

Agriculture plays an industrial and economic role, as well as an environmental and ecological conservation role, group harmony and the inheritance of traditional culture. However, no matter how advanced the industry is, the basic food necessary for human life can only be produced through the photosynthesis of plants with natural resources such as the sun, water, and air. The Food and Agriculture Organization of the United Nations (FAO) predicts that the world's population will increase by another 2 billion people by 2050, and it faces a myriad of complex and diverse factors to consider, including climate change, food security concerns, and global ecosystems and political factors. In particular, in order to solve problems such as increasing productivity and production of agricultural products, improving quality, and saving energy, it is difficult to solve them with traditional farming methods. Recently, with the wind of the 4th industrial revolution, ICT convergence technology and artificial intelligence have been rapidly developing in many fields, but it is also true that the application of new technologies is somewhat delayed due to the unique characteristics of agriculture. However, in recent years, as ICT and artificial intelligence utilization technologies have been developed and applied by many researchers, a revolution is also taking place in agriculture. This paper summarizes the current state of research so far in four categories of agriculture, namely crop cultivation environment management, soil management, pest management, and irrigation management, and smart farm research data that has recently been actively developed around the world.

세계적으로 창업 생태계가 구축되면서 기술창업 분야가 두각을 보이고 있다. 기술창업은 기술력을 통한 지속력뿐 아니라 혁신적으로 변화를 진행시키므로 기술에 대한 투자 동향을 날이갈수록 높아지고 있다. 하지만 기술이 발전하면서 함께 주목되고 있는 분야가 사회적 가치를 가지고 있는 소셜벤처이다. 특히 UN에서 발표한 지속가능한 발전목표(SDGs)의 경우 필수적으로 사업 비즈니스 모델적으로 채택된 분야를 갖고 있어야하며 비재무적성과를 판단하는 기준인 ESG 또한 필수적인 사회적 가치 요소로 떠오르고 있다. 이러한 흐름 속에서 기술 역량을 내세웠을 때와 사회적 가치를 내세웠을 때 투자자들은 어떤 역량과 특성을 더 선호하며 투자 유무가 결정되는지를 분석해보고자 한다. 결국 기술 역량 또는 사회적 가치 둘중 하나를 내세운다는 것은 기업의 이미지를 나타내는것과 같은 의미이다. 이에 기술역량과 사회적 가치가 기업이미지를 유능 또는 따뜻함 중 어떻게 나타나는지 알아보고 투자 유무에 미치는 영향을 보고자 한다. 본 연구에서는 기술창업 기업 기술 범위를 인공지능(AI), 빅데이터, 사물인터넷(IoT), 바이오(Bio)로 총 4개로 분류하였다. 기술 창업의 기술범위를 독립변수로 설정하였으며 기술창업에서 기술역량 또는 사회적 특성을 내세웠을 때 기업이미지가 유능하게 보여지는지 따뜻하게 보여지는지를 알아보고자 한다. 기업이미지가 유능함 또는 따뜻함으로 비춰졌을 때 벤처투자에서 투자 유무가 결정되는지를 검증하고자 한다. 검증 방법에서는 벤처투자자가 아닌 창업교육을 이수하는 대학생들을 대상으로 모의투자를 통해 연구를 진행하고자 한다.

Naval ships that are navigating always have the possibility of colliding, but there is no clear maneuvering procedure for collision avoidance, and there is a tendency to depend entirely on the intuitive judgment of the Officer Of Watch (OOW). In this study, we conducted a questionnaire survey when and how to avoid collision for the OOW in a Constant Bearing, Decreasing Range (CBDR) situation wherein the naval ships encountered obstacles. Using the results of the questionnaire survey, we analyzed the CBDR situation of encountering obstacles, and how to avoid collision in day/night. The most difficult to maneuver areas were Pyeongtaek, Mokpo, and occurred mainly in narrow channels. The frequency appeared on average about once every four hours, and there were more of a large number of ships encountering situations than the 1:1 situation. The method of check of collision course confirmation was more reliable with the eye confirmation results, and priority was given to distance at closest point of approach (DCPA) and time at closest point of approach (TCPA). There was not a difference in DCPA between the give-way ship and stand-on ship, but a difference between day and night. Also, most navigators prefer to use maneuvering & shifting when avoiding collisions, and steering is 10-15°, shifting ±5knots, and the drift course was direction added stern of the obstacles to the direction of it. These results will facilitate in providing officers with standards for collision avoidance, and also apply to the development of AI and big data based unmanned ship collision avoidance algorithms.

The purpose of this study was to develop value-added seasoning products with Korean advanced chile peppers (Capsicum annuum L.) and investigate their physicochemical characteristics based on sensory evaluation. Ninety-seven chile pepper-related products were collected from American local favorites and analyzed based on their compositions. Yeongyang's chile pepper powders were prepared to develop Korean chile pepper seasoning products and measured for total microbial content (3.36 log CFU/g), moisture content (12.43%), total carotenoids (223.46 mg/100 g), vitamin C (290.33 mg/100 g), ASTA color value (149.37), and capsaicinoids (4.06 mg/100 g). Korean chile pepper seasoning samples for beef showed higher overall acceptability compared to American local favorite seasonings. Completed Korean chile pepper seasoning products contained red pepper (20%), various herbs (26.1%), salt (11.4%), dried mushroom (8.5%), garlic (8.5%), black pepper, curry, paprika, sweet pumpkin (5.7%), and citron (2.8%). This result might show the possibility of replacing mixed seasoning products from foreign countries (USA and Europe).

In this study, we are going to study the OTT service platform, which is growing rapidly in recent years. Through this study, the characteristics of the platform preferred by consumers and the relationship between psychological benefits and loyalty were investigated. In addition, the relationship between the type of family and the characteristics of the platform and psychological benefits was investigated. In this study, a total of 255 surveys were conducted targeting consumers who have used OTT services, and 206 cases were analyzed with SPSS 18 and AMOS 21, excluding 49 cases that were insincere or inconsistent internally. According to the results of the study, all factors of convenience, AI recommendation service, and content, which are factors characteristic of OTT platform, had a significant effect on psychological benefits. In addition, psychological benefits were found to have a significant effect on brand loyalty. It was found that there was no difference between the characteristics of the OTT platform and the type of family according to the family type, which is a control variable. This study is significant in providing a theoretical background according to the type of family. Future studies are expected to consider various members or add factors to the study.
