본 논문은 애도의 글쓰기가 공개적이고 공식적인 가족 서사를 보장한다면 고대 문 인들의 가족에 대한 인식 내지 변화된 감정구조를 어느 정도 추론해낼 수 있을 것이 라는 가정하에 기획되었다. 이는 일차적으로 애도 문학 변천의 한 단면을 탐색하는 작업이면서 당시 공동체가 소유했던 가족에 대한 감정구조의 실태 및 변화의 흐름을 구축하는 실마리가 될 수 있으리라 판단했기 때문이다. 연구 결과 고대 중국인들의 가족 서사는 탈관습의 성질을 강하게 드러내고 있음을 확인할 수 있었다. 비록 애도 시문은 죽음이 전제되는 면에서 그 고유의 특수성이 고려되어야 하지만, 글쓰기 활 동을 통해 가족에 대한 언급을 공식화한 시도는 가족 구성원의 존재를 감추지 않고 나름의 방식을 통해 공개하려던 당시 문인들의 진전된 감정 구조가 반영된 것이라 볼 수 있다.

In this study, changes in the microbial ecosystem of the Yeongheungdo island coastal waters were investigated for five years to collect basic data. To evaluate the influence of distance from the coast on the microbial ecosystem, four sites, coastal Site (S1) and 0.75, 1.5, and 3 km away from the coast, were set up and the changes in physicochemical and biological factors were monitored. The results showed seasonal changes in water temperature, dissolved oxygen, salinity, and pH but with no significant differences between sites. For nutrients, the concentration of dissolved inorganic nitrogen increased from 6.4 μM in April-June to 16.4 μM in July-November, while that of phosphorus and silicon phosphate increased from 0.4 μM and 2.5 μM in April-June to 1.1 μM and 12.0 μM in July-November, respectively. Notably, phosphorus phosphate concentrations were lower in 2014-2015 (up to 0.2 μM) compared to 2016-2018 (up to 2.2 μM), indicating phosphorus limitation during this period. However, there were no differences in nutrients with distance from the coast, indicating that there was no effect of distance on nutrients. Phytoplankton (average 511 cells mL-1) showed relatively high biomass (up to 3,370 cells mL-1) in 2014-2015 when phosphorus phosphate was limited. Notably, at that time, the concentration of dissolved organic carbon was not high, with concentrations ranging from 1.1-2.3 mg L-1. However, no significant differences in biological factors were observed between the sites. Although this study revealed that there was no disturbance of the ecosystem, further research and more basic data on the microecosystem are necessary to understand the ecosystem of the Incheon.

The study used the whole-life carbon assessment method to conduct a thorough carbon-neutral evaluation of a standard steel structure. To further assess carbon emissions, 11 design-changed models were evaluated, with changes made to the span between beams and columns. The results of the carbon emission assessment showed savings of approximately 13.1% by implementing the stage of the beyond life cycle. Additionally, the evaluation of carbon emissions through design changes revealed a difference of up to 42.2%. These findings confirmed that recycling and structural design changes can significantly reduce carbon emissions by up to 48.6%, making it an effective means of achieving carbon neutrality. It is therefore necessary to apply the stage of beyond life cycle and structural change to reduce carbon emissions.

This study examines the textual structure and speech acts within the inaugural addresses of the ministers in the Yoon Suk Yeol Government’s first cabinet. These addresses typically follow a three-part structure: introduction, development, and closing. The introduction features an opening greeting, while the development stage outlines the main service and missions, and presents requests to organizational members. The closing stage concludes the address. The introduction and closing are often simple enumerations of contents, whereas the development stage is logically and coherently structured. In terms of speech acts, the introductory stage predominantly features expressive acts. The development stage is marked by announcements and requests, while the closing e ncompasses various acts including statements, promises, and solicitations.

Recently, Free-Form and Irregular Shape high-rise buildings are constructed by IT technology development. Tilted shaped high-rise building which is one of Irregular shape high-rise buildings can cause lateral displacement by gravity load and lateral load due to tilted elevation shape. Therefore, it is necessary to review the behavior and structural aspects of the Tilted shape high-rise building by gravity load. In this paper, the dynamic characteristics of a tilted structure with a dual-core were analyzed with the core location as a design variable, and response behavior, vulnerable members, and vulnerable layers to earthquake loads were analyzed. As a result of the analysis, as the location of the core moved in an tilted direction, the eccentric distance and eccentric load decreased, reducing the axial force of the vertical members. However, the location of the core had little effect on the response.

최근 우리는 Hg2+에 대한 높은 선택성을 가지며 Hg2+와 결합하여 밝은 녹색 형광을 보이는 tetraphenylethylene-bis(thiophen-2-ylmethyl)amine (TPE-BTA)의 착화합물(TPE-BTA-2Hg2+)의 구조를 밝혀내기 위해 시 간 의존적(time-dependent, TD) 밀도 함수 이론(DFT)을 이용하였다. 그러나 우리는 이 과정 속에서 Hg2+ 이온에 대한 모든 전자(all electron, AE) basis set인 x2c-TZVPPall만이 실험 스펙트럼에 가까운 흡수 및 형광 스펙트럼을 성공적으 로 재현한다는 것을 발견했다. 많이 알려져 있는 effective core potential (ECP) 기반인 LANL2DZ는 형광스펙트럼 계산 과 관련된 들뜬 상태의 구조 최적화 계산을 모두 실패했으며 또한, LANL2DZ는 첫 번째 들뜬 상태의 최적화 과정에서 너무 작은 형광 에너지를 제공했다. 이때 LANL2DZ는 리간드와 Hg2+ 사이의 거리가 증가함에 따라 빠르게 감소하는 HOMO-LUMO gap을 제공하는 반면, x2c-TZVPPall은 점진적으로 감소하는 안정적인 HOMO-LUMO gap을 보여줬다. 우리는 적어도 Hg2+ 이온을 포함하는 착화합물 시스템에서 ECP에서 발생하는 기하학적 문제들을 피하기 위해서는 모 든 전자 기본 세트를 사용하거나 새로운 ECP를 만들어야 된다고 조심스럽게 제안한다.

This study aims to evaluate the structural safety of a structural thermal barrier, installed inside the structure of a building and performed the role of a load-bearing element and an insulation simultaneously, contributing to the realization of net-zero buildings. To ensure the reliability of the analysis model, the analysis results derived from LS-DYNA were compared with the experimental results. Based on the results shown through the flexural experiment, the reliability of the thermal cross-section insulation structure model for slabs was validated. In addition, the effect of the UHPC block on the load support performance and its contribution to vertical deflection was verified.

In order to enhance competitiveness in the industry, financial companies are building a high level of customer satisfaction and repurchase intention by further strengthening not only the technical quality of the platform business but also the customer-oriented service quality. Theoretically, it is time for a theoretical review of whether the expansion of service quality using platform business in the financial industry is directly linked to the performance of financial companies, such as satisfaction and repurchase intention of existing customers. Based on the rapid growth of mobile and the main activities of financial platform companies above, This study attempted to test a significant impact on customer satisfaction and reuse intention on information services and system services, which are service quality of mobile financial platforms. Even if a number of financial companies compete with each other, they could survive by dividing the market, In the digital environment, customers have free access, so the winner can monopolize the market. It is an environment in which customers can move to platform companies that provide better services. The contents presented through the results in this study will be able to be used strategically in terms of the implementation and operation of the financial platform. In addition, it served as an opportunity to find independent variables that affect customer satisfaction and reuse intention, which are financial platform service quality, and suggested the possibility of continuous development of the platform in the future. In summary, the service quality of financial platforms can further expand users by emphasizing user visibility in terms of information services and utilizing user-centered financial platforms that increase customer satisfaction and reliability by strengthening the responsiveness and ease of system services. This study is of important value and is believed to have laid an important foundation for future research.

Recently, carbon composites have been applied to various fields. However, carbon composites have not been applied to the fishing vessel field due to its structure standards centered on glass composites. In this study, a structural strength evaluation study was conducted for the application of carbon composites in the fishing vessel field. Hull minimum thickness verification test and hull joint verification test were conducted. Compared to glass composites, the verification was based on equivalent or better performance. The results show that carbon composites can reduce the weight by 20% compared to glass composites. For hull joints, it was necessary to increase the thickness of the joint seam by the thickness of the hull to apply carbon composite. Through this study, a standard for the application of carbon composites to fishing vessel can be established.

BNKT Ceramics, one of the representative Pb free based piezoelectric ceramics, constitutes a perovskite(ABO3) structure. At this time, the perovskite structure (ABO3) is in the form where the corners of the octahedrons are connected, and in the unit cell, two ions, A and B, are cations, A ion is located at the body center, B ion is located at each corner, and an anion O is located at the center of each side. Since Bi, Na, and K sources constituting the A site are highly volatile at a sintering temperature of 1100℃ or higher, it is difficult to maintain uniformity of the composition. In order to solve this problem, there should be suppression of volatilization of the A site material or additional compensation of the volatilized. In this study, the basic composition of BNKT Ceramics was set to Bi0.5(Na0.78K0.22)0.5TiO3 (= BNKT), and volatile site (Bi, Na, and K sources) were coated in the form of a shell to compensate additionally for the A site ions. In addition, the physical and electrical properties of BNKT and its coated with shell additives(= @BNK) were compared and analyzed, respectively. As a result of analyzing the crystal structure through XRD, both BNKT(Core) and @BNK(Shell) had perovskite phases, and the crystallinity was almost similar. Although the Curie temperature of the two sintered bodies was almost the same (TC = 290 ~ 300 ℃), it was confirmed that the d33 (piezoelectric coefficient) and Pr (residual polarization) values were different. The experimental results indicated that the additional compensation for a shell additive causes the coarsening, resulting in a decrease in sintering density and Pr(remanent polarization). However, coating shell additives to compensate for A site ion is an effective way to suppress volatilization. Based on these experimental results, it would be the biggest advantage to develop an eco-friendly material (Lead-free) that replaced lead (Pb), which is harmful to the human body. This lead-free piezoelectric material can be applied to a biomedical device or products(ex. earphones (hearing aids), heart rate monitors, ultrasonic vibrators, etc.) and skin beauty improvement products (mask packs for whitening and wrinkle improvement).
