This study examines options to revitalize a B2B textile trading platform, exploring user satisfaction and perceptions of the importance of several website features. Between June 8 and June 21, 2023, fashion studies majors and domestic fashion brand product planners were asked to use the website of an open B2B textile platform for 30 minutes and then evaluate its features by responding to a survey. The final sample for analysis wad comprised of 150 questionnaires. To analyze the key textile website features, a paired t-test, Importance-Performance Analysis (IPA), and multiple regression analysis were utilized. The analysis classified the key textile website features related to user importance and satisfaction into the following categories: convenience, appearance, product information, and uniqueness. An analysis investigation of the differences in importance and satisfaction for each website evaluation attribute found significant differences in 12 attributes. The IPA analysis revealed that attributes such as product reliability, quality, a convenient search function, and convenient page movement are highly important to users and garner high user satisfaction; these findings demonstrate the importance of maintaining these elements. Images on the main screen, the latest trend information, and product prominence attributes also garner high importance ratings, but result in low user satisfaction, which signifies extensive revision is required. Finally, user evaluation of the convenience, appearance, and product information of the website was found to affect user recommendation intention.

생물다양성협약 당사국총회 결의에 따르면, 환경영향평가란 제안된 계획 또 는 개발이 환경에 미칠 것 같은 영향을 이익적 측면과 불리한 측면에서 사회경 제적, 문화적 및 인간의 건강에 미치는 영향과 연계하여 평가하는 과정을 의미한다. 해양에서의 환경영향평가 제도는 다수의 국가에 의해 국내법적으로 수용 하여 수행되어왔으며, 국제적으로도 많은 환경협약과 하위 지침들로부터 의무 화하여 수행되고 있다. 국제법상 국가관할권 이원지역에 대한 환경영향평가의 수행의무는 분명히 존재한다. 최근 채택된 BBNJ협정은 국가관할권 이원지역에 대한 종합적인 환경 및 해양생물다양성 보호를 목적으로 하는데, 그중 제4부는 환경영향평가의 발동요건, 절차, 평가의 내용, 협의과정, 의사결정 등 환경영향 평가 수행 전반에 대한 요건을 서술하고 있다. 본 연구에서는 다수의 환경영향 평가와 관련된 기존제도들 중 국가관할권 이원지역만을 협약의 적용지역으로 하고, 명확히 환경영향평가의 의무를 부과하고 있는 남극조약체제 및 국제해저 기구 주관하의 심해저 광업규칙상 환경영향평가제도와 BBNJ협정상 환경영향 평가제도의 비교를 통해 환경보호의 대응기조가 어떻게 유사하게 반영되었는 지 또는 차이점이 있는지 살펴보고 그 실효성에 대하여 논한다. 결론적으로 1) 기존제도와 달리 BBNJ협정은 call-in mechanism의 적용을 통 해 환경영향평가서에 대한 최종 의사결정권을 당사국에게 부여하고 있다. 2) 국가관할권 내측 지역으로부터의 월경 오염에 대한 환경영향평가 절차를 포함 함으로써 월경오염에 대한 준수의 효과성을 보장하고자 하였다. 3) 대중통고 및 협의, 활동의 영향에 대한 검토 조항을 통해 환경영향평가의 절차에서 넓은 범위의 이해관계자를 포함하고, 기존제도와 달리 국가관할권 이원지역에서의 활동으로부터 야기된 월경오염으로 영향을 받을 수 있는 연안국을 명시하여 환 경영향평가 절차에서 역할을 부여하고 있다. 4) 기존제도상 환경영향평가시 고 려되던 누적영향 및 잔존영향에 더하여 전략환경평가라는 현대적 보전기법을 규정하고 있다. 남극조약체제 및 국제해저기구 주관하의 심해저 광업규칙상 환 경영향평가제도 역시 과거 작성되었던 규칙에 대비하여 비교적 최근의 규칙 및 현재 작성중인 문서에서 대중통고 절차 신설, 확장된 이해관계자의 참여 근거 규정 마련 등에 따라 환경보호를 위한 국제사회의 강화된 기조에 대응하고 있 음을 살펴볼 수 있었다. 향후 당사국 총회를 통해 환경영향평가의 세부 지침이 보완될 것임에 따라, 기존의 관련 제도상 환경영향평가 절차 및 내용에 대한 정확한 숙지를 기반으로 하여 대응해 나가야 할 것이다. 또한 관련 전문기관을 지정하고 과학 전문가 양성에 집중해야 할 것이다.

In response to the global trend of making sustainable development an urgent task, luxury fashion brands actively embrace it in their corporate philosophies and management policies. However, despite the widespread consensus in the related industry and the strong will of companies for the sustainable development of luxury brands, there are still few cases of luxury fashion brands successfully implementing sustainable development. This study examined the impact of the types of message framing on the sustainability marketing of luxury fashion brands, focusing on their effects on perceived message effectiveness, sustainable brand image, and brand attitudes. An online survey was administered to 464 Korean consumers in their 20s to 40s to test the hypotheses. The results showed that perceived effectiveness was higher for negatively framed messages (loss) than for their positive counterparts (gain). The types of message framing did not significantly affect sustainable brand messages, and no significant difference in perceived brand image was found, regardless of message type. Perceived message effectiveness exerted a significant positive effect on sustainable brand image, and such an image had a significant positive effect on brand attitudes. The results provide implications for related research and practical implications for the development of competitive sustainability marketing strategies for luxury fashion—an industry still in its infancy.

Biocide dichlofluanid breaks down quickly and accumulates easily in sediment, potentially causing a persistent impact on various marine organisms. We analyzed the potential toxicity of dichlofluanid on major aquaculture species in Korea, Undaria pinnatifida. Female gametophytes of U. pinnatifida were exposed to dichlofluanid at concentrations of 0, 1, 2, 4, 8, 16, and 32 mg L-1, and their survival and relative growth rate were analyzed. The no observed effect concentration (NOEC), lowest observed effect concentration (LOEC), and median lethal concentration (LC50) for female gametophyte survival were determined as 1, 2, and 10.82 (95% CI: 8.87-13.23) mg L-1, respectively. The NOEC, LOEC, and median effective concentration (EC50) for relative growth rate were 1, 2, and 6.58 (95% CI: 6.03-7.17) mg L-1, respectively. Female gametophytes of U. pinnatifida were expected to experience toxic effects at concentrations above 2 mg L-1 of dichlofluanid. These research findings are expected to serve as important reference data for evaluating the toxicity effects of U. pinnatifida in its early life stages when exposed to dichlofluanid.

Herbicide-resistant transgenic rapeseed (TG rapeseed) was developed by inserting phosphinothricin acetyltransferase (PAT, bar), a modified gene from the soil bacterium Streptomyces hygroscopicus, into the genome of a conventional variety of rapeseed (Youngsan). The TG rapeseed used for the test was confirmed to express the PAT gene by polymerase chain reaction (PCR) and immunostrip. Feeding tests were conducted with Cyprinus carpio to evaluate the environmental risk of TG rapeseed, including the herbicide resistant gene. C. carpio was fed 100% ground rape suspension, TG rapeseed, or non-genetically modified (GM) counterpart rapeseed (Youngsan). As a result, the feeding test showed no significant differences in the cumulative immobility or abnormal response between C. carpio samples fed on TG rapeseed and non-GM counterpart rapeseed. The 48 h-LC50 values of the TG rapeseed and the non-GM counterpart rapeseed were 3,376 mg/L (95 % confidence limits: 3,169 - 3,596 mg/L) and 2,682 mg/L (95 % confidence limits: 2,267 – 3,123 mg/L), respectively. The rape NOEC (no observed effect concentration) value for C. carpio was suggested to be 625 mg/L. Based on these results, there was no significant difference in the toxicity for non-target organisms (C. carpio) between the TG rapeseed and non- GM counterparts.

PURPOSES : In this study, the resources and energy consumed to produce hot mix asphalt mixtures and hot mix reclaimed asphalt mixtures in asphalt concrete plants were estimated and the emissions from the detailed processes of the production process were evaluated based on TRACI(the tool for the reduction and assessment of chemical and other environmental impacts). METHODS : To estimate the energy consumption of the aggregate drying process, which consumes a significant amount of energy in the production process, an energy consumption calculation model based on the thermal equilibrium equation was used, and the energy consumed for material transportation, storage, and operation of other facilities was cited from the literature. RESULTS : For the system boundary conditions established and the inventory considered, the emissions to produce one ton of hot mix reclaimed asphalt mix are greater than the emissions to produce one ton of hot mix asphalt mix for a number of key impact categories. The process of producing hot mix reclaimed asphalt mixtures was evaluated to consume more resources and energy in the production of recycled aggregates and heating for drying than in the production of hot mix asphalt mixtures, but less resources and energy in the production of binders and natural virgin aggregates and the heating to heat these materials. CONCLUSIONS : The results of the emissions assessment using the life cycle inventory for the production of hot mix asphalt mixtures were generally similar to the results understood in the field and in much of the literatures, confirming the reliability of the methodology. However, in order to evaluate the dominance of specific processes or mixtures, it is believed that the construction of a wide range of inventory databases after inventory redesign is necessary for a specific and rigorous assessment.

PURPOSES : The purpose of this study is to verify the influences on the compactibility evaluation of WMA (Warm Mix Asphalt) mixture by laboratory experiments. METHODS : Two types of WMA additives (chemical and wax types) and two types of compactors (marshall and gyratory) are used in laboratory experiments. In addition, two types of WMA processes (wet and dry) are tested to verify the impact of manufacturing process. RESULTS : The laboratory results show that the effects of compaction method on compactibility are different depending on the type of additive. The compaction method has a significant impact on WMA mixture with chemical type additive to extent that it determines whether required criterion is satisfied, but only little on WMA mixture with wax type additive. In the case of wet process for WMA mixture manufacturing, it is hard to assess the air void of HMA mixture made of same asphalt binder used in WMA mixture since the additive has already been added in asphalt binder. And the test results show that air voids of HMA mixture vary within properties of asphalt binder. CONCLUSIONS : Through this study, it is found that compactibility of WMA mixture is affected by the compaction methods depending on the additive types and by the WMA mixture manufacturing process. Therefore, those are recommended to be considered when evaluating compactibility of WMA mixtures.

PURPOSES : This research assesses the influence of emulsified asphalt on vegetation growth by examining parameters such as moisture content, temperature, pH, electrical conductivity, and analyzing the extent of green coverage using image analysis. METHODS : Within this study, sensors were employed to measure the growth environment of vegetation treated with emulsified asphalt. Furthermore, the analysis of the greening rate through image analysis has been incorporated. RESULTS : Research indicates that emulsified asphalt effectively secures seeds to surfaces and maintains moisture content for an extended period. However, the excessive utilization of emulsified asphalt has been observed to reduce germination and greening rates. CONCLUSIONS : The application of an optimal emulsified asphalt content is presumed to promote vegetation growth. To establish objective, it is imperative to conduct comprehensive research on its long-term structural effects regarding growth, greening rate, and slope when integrated with emulsified asphalt.

PURPOSES : There has been increasing interest in South Korea on warm-mix asphalt (WMA) and cold-mix asphalt (CMA) technologies that allow production of asphalt pavement mixtures at comparatively lower temperatures than those of hot-mix asphalt (HMA) for use in pavement engineering. This study aims to evaluate the feasibility of replacing HMA pavement with WMA pavement with the goal of reducing CO2 emissions associated with asphalt production for road construction. METHODS : Changes in the dynamic modulus characteristics of WMA and HMA according to short-term and long-term aging were evaluated. In addition, the effects of water damage were evaluated for short- and long-term aging stages. RESULTS : For WMA, in the process of mixing and short-term aging, early-age dynamic modulus decreased owing to low temperature and reduced short-term aging (STA) time. This could result in early damage to the asphalt pavement depending on the applied traffic load and environmental load. CONCLUSIONS : Mastercurves of the dynamic modulus were used for comparative analysis of WMA and HMA. Compared to the dynamic modulus after STA of HMA, the estimated aging time determined by experiments for WMA to achieve the required stiffness was more than 48 hours, which is equiva-lent to approximately 4 to 5 years real service life when converted. It is considered that further studies are needed for performance optimization to achieve early-age performance of the asphalt mixes.

Approximately 40,000 elevators are installed every year in Korea, and they are used as a convenient means of transportation in daily life. However, the continuous increase in elevators has a social problem of increased safety accidents behind the functional aspect of convenience. There is an emerging need to induce preemptive and active elevator safety management by elevator management entities by strengthening the management of poorly managed elevators. Therefore, this study examines domestic research cases related to the evaluation items of the elevator safety quality rating system conducted in previous studies, and develops a statistical model that can examine the effect of elevator maintenance quality as a result of the safety management of the elevator management entity. We review two types: odds ratio analysis and logistic regression analysis models.

본 연구는 코마개의 사용 여부에 따라 MRI 영상을 분석함으로써 숨 참기의 정확도를 향상할 도구로써 코마개가 실 효성이 있는지 검증하고자 하였다. 이를 위해 수검자에게 코마개가 없는 자연 호흡과 코마개를 사용한 구강 호흡 상태에서 호기 후 숨 참기를 지시하고 MRI 영상을 획득하였다. 영상은 2D 경사 자기장 에코 시퀀스로 획득하였고 초당 1장씩, 총 15장을 얻어 숨 참기 상태를 분석하였다. 숨 참기의 상태를 정량적으로 평가하기 위해 우측 폐 면적 을 측정하였다. 그리고 첫 번째 영상의 폐 면적을 기준으로 나머지 영상들에서 폐 면적의 절대 오차값을 구해 비교하 였다. 더불어 첫 번째 영상을 기준으로 나머지 영상들의 기하학적 유사도를 평가하기 위해 SSIM 값을 계산하였다. 실험 결과, 자연 호흡 상태에서 절대 오차는 평균 216.79 ㎟로 나타났다. 반면, 코마개를 사용한 구강 호흡의 경우 평균 55.94 ㎟로 나타나 자연 호흡과 비교하여 약 74.19% 감소하였다. SSIM 값은 자연 호흡 시 평균 0.7, 구강 호흡 시 0.76으로 나타나 기하학적 유사도가 약 6% 향상되었다. 이는 코마개 사용 시 호흡의 초기 상태를 잘 유지함 으로써 숨 참기의 정확도가 향상되어 능동적으로 호흡 상태를 조절할 수 있는 도구로써 충분한 가치가 있음을 증명한 다. 따라서 복부 MRI 검사에서 호흡에 따른 인공물을 개선하는 데 코마개가 도움을 줄 수 있으며 영상 개선 및 업무 효율을 높이는 도구로써 충분히 활용할 수 있다.

최근 우리사회에서 젠더갈등이 지역, 이념, 세대와 더불어 새로운 갈등 으로 부상하는 가운데 20대 대통령선거를 통해 유권자의 관심이 집중되 었다. 본 연구의 목적은 청년세대 남녀 간 갈등으로 취급되었던 젠더갈 등 이슈가 20대 대통령선거에서 쟁점으로 부각되면서 유권자의 주요 정 당 대통령후보에 대한 평가와 투표선택에 어떤 영향을 주었는가를 경험 적으로 분석하는 것이다. 당시 논쟁이 되었던 젠더갈등 이슈로 여성가족 부 폐지를 비롯해 여성할당제 폐지, 여성 병역의무화, 남성 육아휴직이 며, 주요 정당의 대선후보 평가를 후보 호감도와 국정운영 능력 평가로 분석한 결과 윤석열 후보와 이재명 후보의 호감도와 국정운영 능력 평가 전반에 지속적으로 영향을 미친 젠더갈등 이슈는 여성가족부 폐지였다. 또한 여성가족부 폐지 외 두 후보의 평가에 영향을 준 젠더갈등 이슈는 여성 병역의무화와 남성 육아휴직이었다. 마지막으로 두 후보에 대한 유 권자의 투표결정에 영향을 준 젠더갈등 이슈는 여성가족부 폐지로, 여성 가족부 폐지가 유권자의 대선 후보자에 대한 전반적인 평가는 물론 투표 선택에도 결정적 영향을 준 선거의 쟁점 이슈임을 여실히 증명했다.
