The steel wire or steel bar processing process applied to the manufacture of various bolts and power transmission shafts was improved by applying in-line phosphate film treatment technology. By applying a polymer lubricant for a non-reactive metal forming process and a non-reactive non-phosphorus lubricating coating agent, the film formation for each process time was comparatively analyzed and reviewed. Compared to the nine processes applied previously, the in-line phosphate film treatment technology applied with only two processes has been effectively improved in terms of reduction of treatment time, reduction of facility installation area, prevention of water pollution due to wastewater, and non-use of ozone-depleting substances. In addition, it was found that it can have an important effect on productivity improvement and price competitiveness from the simplification of quality control and process control as well as improvement of the working environment.

In recent years, many countries are committing to environmental conservation. Following this trend, successful policy implementation of SDGs with ESG management extended to the public sector is emerging as a keyword determining the success or failure of the capital market, countries, and individual companies. Accordingly, many countries are implementing various policies related to the environment. One of them is to implement national policies by introducing environmental taxes. These policies use environmental taxes to control pollution by indirectly influencing the behavior of producers or consumers through economic incentives rather than directly interfering with environmental pollution behavior. This study examines the status of environmental taxes in marine tourism sites in Korea, reviews the effectiveness of such policies, and suggests how to improve them by identifying limitations of the current system.

Purpose: In the post-COVID-19, many consumers still feel uncomfortable with crowding in closed spaces. This study investigates how non-crowding affects consumer satisfaction and restaurant visit intention. Research design, data, and methodology: The data were collected from 350 people aged 20 and above. A total of 347 respondents, excluding 3 unfaithful respondents, were analyzed using Smart PLS 4.0 program. Result: Both spatial and human crowding have significant effects on satisfaction. On the other hand, neither spatial nor human crowding directly affected dine-out intention significantly. In addition, spatial crowding was found to have a direct and significant effect on in-store dining intention, but human crowding did not have a direct and significant effect on in-store dining intention. It was found that satisfaction had a significant effect on both dine-out intention and in-store dining intension. Conclusions: This study has expanded the range of consumer behavioral intentions by applying a non-crowded environment (S) to the SOR theory. Also, Consumer behavioral intention was expanded by dividing visit intention into a dine-out and in-store dining intention. Therefore, we propose measures to minimize human crowding by introducing a system such as adjustment of store operating hours, reservation system, store opening time alarm system, and reduction of cooking time.

최근 멀티미디어 응용에서 XML은 메타데이터를 표현하기 위하여 그 사용량이 증가하고 있는 추세이며, 그 예로는 MPEG-7 MDS, MPEG-21등이 있다. 이러한 XML형식의 메타데이터의 크기를 줄이기 위하여 MPEG-7에서 정의한 포맷이 Binary Format for Metadata(BiM)이다. BiM은 스트리밍을 고려하여 단편화를 통한 점진적인 전송이 가능하며, 압축률이 높고 복호화에 따르는 오버헤드가 작다는 장점을 제공한다. 본 논문에서는 BiM에 대한 간단한 소개와 모바일 환경에 적합하도록 구현한 BiM 복호기의 설계 및 구현에 대하여 소개한다.구현한 복호기는 모바일 환경의 다양한 플랫폼에서의XML 파싱 모듈과 DOM 트리모듈에 대한 종속성을 제거하기 위하여, 스키마 파일의 파싱을 데스크탑에서 수행하고 이에 대한 파싱 결과를 자체 정의한 Syntax File 형식으로 복호기에 전송할 수 있도록 하였다. 또, BiM형태로 전송되는 ESG 메타데이터와 MPEG-4 LASeR 스트림에 대하여 Windows, Windows CE, embeded Linux 환경에서 정상적으로 복호화 하는 것을 확인하였다.

This study was carried out to examine seaweed community structure and distribution of crustose coralline algae at the intertidal and subtidal zones of Gallam, Samchuk, eastern coast of Korea. Total 112 species including 14 of green algae, 33 of brown algae, and 65 of red algae were collected and identified. Among these species, 29 species were found throughout the year. The dominant species which contributed significantly to the total biomass were Ulva pertusa, Colpomenia spp., Sargassum fulvellum, Sargassum fusiforme, Sargassum muticum, Sargassum thunbergii, Corallina pilulifera, and Gelidium elegans. Annual seaweed biomass in dry weight was 66.7 $gm^{-2}$ and maximum biomass was recorded seasonally in summer (107.5 $gm^{-2}$), while minimum was recorded in autumn (36.2 $gm^{-2}$). In seaweed functional group analyses, coarsely branched form was the most dominant functional group constituting from 40.0 to 48.6% of the total flora. Ecological state group ESG II, as an opportunistic species, including sheet form, filamentous form, and coarsely branched form, consisted of 46~61 species, constituting 76.7~82.4%. Crustose coralline algae was observed throughout all seasons. Species of the crustose coralline algae were largely classified into Lithothamnion lemoineae, Lithophyllum okamurai, Lithophyllum yessoense, and Hydrolithon gardineri. The coverage of crustose coralline algae seems to be lower than that of other studies from 36.8% to 11% on average.

As interest in the sustainable fashion industry continues to increase along with climate issues, it is necessary to identify research trends in sustainable fashion and seek new development directions. Therefore, this study aims to analyze research trends on sustainable fashion. For this purpose, related papers were collected from the KCI (Korean Citation Index) and Scopus, and 340 articles were used for the study. The collected data went through data transformation, data preprocessing, topic modeling analysis, core topic derivation, and visualization through a Python algorithm. A total of eight topics were obtained from the comprehensive analysis: consumer clothing consumption behavior and environment, upcycle product development, product types by environmental approach, ESG business activities, materials and material development, process-based approach, lifestyle and consumer experience, and brand strategy. Topics were related to consumption, production, and education of sustainable fashion, respectively. KCI analysis results and Scopus analysis results derived eight topics but showed differences from the comprehensive analysis results. This study provides primary data for exploring various themes of sustainable fashion. It is significant in that the data were analyzed based on probability using a research method that excluded the subjective value of the researcher. It is recommended that follow-up studies be conducted to examine social trends.

This paper seeks to raise inflection points of battery manufacturing bases in Korea in the V4 region through the reorganization of new industrial technologies in accordance with ESG. As a result, the global supply chain market is cut off. The Russian-Ukraine war and the U.S.-China hegemony are competing in the economic crisis caused by COVID-19. It is showing diversification of new suppliers in an environment where mineral, grain procurement, gas, and even wheat imports from China and Russia are not possible. As a protective glocal, this area is used as a buffer zone(Pro-Russia, Hungary). to an isolated zone(anti-Russia, Poland) by war. In this paper, economic growth is expected to slow further due to the EU tapering period and high inflation in world countries. Due to these changes, the conversion of new tech industry and the contraction of Germany's structure due to energy supply may lose the driving force for economic growth over the past 20 years. This is caused by market disconnection(chasm) in the nominal indicators in this area. On the other hand, Korea should actively develop into the V4 area as an energy generation export (nuclear and electric hydrogen generation) area as a bypass development supply area due to the imbalance in the supply chain of rare earth materials that combines AI. By linking this industry, the energy platform can be scaled up and reliable supply technology (next generation BT, recycling technology) in diversification can be formed in countries around the world. This paper proves that in order to overcome the market chasm caused by the industries connection, new energy development and platform size can be achieved and reliable supply technology (next-generation battery and recycling technology, Low-cost LFP) can be diversified in each country.
