Open platform technology in the banking industry is anticipated to impact the market very positively together with the activation of Fin Tech services. The domestic environment of payment services has been rapidly changing into the mobiles and multiple new payment services have been introduced from a variety of vendors. However, the convenience of payment always causes worsening the security, and the accidents on the security have been continued to occur such as leakage of personal information, hacking and so on upon the expansion of the industry and the market size. This study aims to analyze the status of Fin Tech open platforms and various problems of the related standard technologies, and to suggest the possible solutions. Upon the analysis results, it was confirmed that multiple solutions were required to improve the main security protocols of open platforms and to process the security functions diversely. In conclusion, the results of this study will be helpful to determine the direction of the solution on the security issues in the open platform environment of the current industry.

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.

The slowdown of the global economic market due to the pandemic is causing the global construction market to stagnate, and the use of smart construction technology is drawing attention as one of the main alternatives to overcome this problem. In fact, a number of previous studies have been published that smart construction technologies such as building information modeling and drones can contribute to project performance improvement, such as productivity improvement and cost reduction. However, previous studies focus on the application direction and technical effectiveness of smart construction technology, so the analysis in terms of the contribution that the application of the technology has to the project performance is insufficient. Therefore, the purpose of this study is to focus on the effectiveness aspect of the application of smart construction technology on the project performance. The results of this study are expected to be able to be used as basic data for establishing policies related to the activation of smart construction technology promoted by the government and setting the direction for the use of smart construction technology by stakeholders.

The purpose of this study is to analyze user perceptions of tourism platforms through big data. Data were collected from Naver, Daum, and Google as big data analysis channels. Using semantic network analysis with the keyword 'tourism platform,' a total of 29,265 words were collected. The collection period was set for two years, from August 31, 2021, to August 31, 2023. Keywords were analyzed for connected networks using TexTom and Ucinet programs for social network analysis. Keywords perceived by tourism platform users include 'travel,' 'diverse,' 'online,' 'service,' 'tourists,' 'reservation,' 'provision,' and 'region.' CONCOR analysis revealed four groups: 'platform information,' 'tourism information and products,' 'activation strategies for tourism platforms,' and 'tourism destination market.' This study aims to expand and activate services that meet the needs and preferences of users in the tourism field, as well as platforms tailored to the changing market, based on user perception, current status, and trend data on tourism platforms.

본 연구는 에너지음료시장 활성화를 위한 패키지디자인 연구전략에 관한 탐색적 연구로써 2016년10월 24일부터 28일까지 국내외에 판매 중인 에너지음료의 사례분석과 에너지음료 패키지디자인의 선호도를 연구하였다. 연구 결과 첫째, 에너지음료의 패키지디자인 중 색상에 대한 사항으로 파란색과 붉은색의 두 가지 색상에 대하여 선호도가 높게 나타났다. 특히 파란색은 62.8%로 가장 선호도가 높았으며 색상을 선택한 이유로는 에너지음료를 떠올리는 이미지이며 눈에 잘 띄어서 그렇다는 응답이 높았다. 둘째, 에너지음료의 포장재질에 대한 선호도를 조사한 결과 대부분 캔과 유리재질을 선택하였으며 그 중 캔에 대해 가장 선호했다. 셋째, 캘리그래피에 대한 선호도 조사한 결과 거친 이미지를 선호하여 에너지음료가 주는 역동적인 이미지로 인한 것으로 보여 진다. 넷째, 패키지디자인 인식은, 어느 한 요소보다는 전체적인 이미지를 중시하였다. 연구의 한계점은 연구 조사 대상이 대전, 충남지역 대학생만 대상으로 연구하여, 향후 패키지디자인의 전반적인 요소와 다양한 연구 대상을 분류하여 에너지음료의 주요 소비층 및 소비지역을 고려한 연구가 이루어져야 할 것이다. 본 연구에서는 패키지디자인은 어느 한 요소를 중요시하기 보다는 전체적인 제품 이미지에 맞게 패키지디자인 전략이 필요하다는데 연구의 시사점과 의미가 있다.

Liquid urea based SCR has been used in the market to reduce NOx in the exhaust emission of the diesel engine vehicle. This system has several problems at low temperature, which are freezing below $-12^{\circ}C$, solid deposit formation in the exhaust, and difficulties in dosing system at exhaust temperature below $200^{\circ}C$. Also, it is required complicated exhaust packaging equipment and mixer due to supply uniform ammonia concentration. In order to solve these issues, solid urea, ammonium carbonate, and ammonium carbamate are selected as ammonia sources for the application of solid SCR. In this paper, basic research on reaction rate of three ammonia-transporting materials was performed. TGA (Thermogravimetric Analysis) and DTA (Differential Thermal Analysis) tests for these materials are carried out for various heating conditions. From the results, chemical kinetic parameters such as activation energy and frequency factor are obtained from the Arrhenius plot. Additionally, from test results of DSC (Differential Scanning Calorimeter) for these materials, chemical kinetic parameters using the Kissinger method are calculated. Activation energies of solid SCR from this experiment are compared with proper data of literature study, then obtained data of this experiment are used for the design of reactor and dosing system for candidate vehicle.

Continuous lifting and carrying of babies constitutes a serious physical burden, leading to issues such as muscle fatigue and pain in child-care workers. However, there is a lack of research on the pressure and subjective comfort of baby carriers that are commercially available in the market. Therefore, this study was intended to determine the most comfortable and least burdensome type of baby carrier. This was done by analyzing muscle activity and pressure when subjects carried babies using three types of baby carriers. The types of baby carriers evaluated included a 'baby carrier of thin shoulder straps without back support band (X-type)', a 'baby carrier with a back-support band and without a hip sheet (H-type)', and a 'baby carrier with back support band and hip support (H-hip type). The subjective comfort of subjects wearing each type of baby carrier was investigated and compared to the objectively measured data. As a result, the X-type baby carrier showed the heaviest pressure on the shoulders and the subjective comfort was found to not be good. On the waist region, the H-type and H-hip type baby carriers showed significantly less muscle activation than the X-type baby carrier. However, subjects showed a stronger preference for the X-type baby carrier on the waist region, despite greater muscle activation. This appears to be because although the back-support band disperses the weight and thus improves physiological comfort; the wearers feel cramped and thus, lower their psychological comfort.
