Cryptic stages of diverse macroalgae present in natural substrata, “the bank of microscopic forms”, were isolated into clonal cultures and identified based on both morphological characteristics and DNA barcoding. Approximately 120 clonal isolates from 308 natural substratum samples were collected from the entire coastline of Kuwait. Amongst these isolates, 77 (64%) were identified through DNA barcoding using the nuclear ribosomal small subunit, RuBisCO spacer (ITS2, tufa, rbcL, psaA, and psbA) and sequencing. Twenty-six isolates (34%) were identified in the division Chlorophyta, 18 (23%) as Phaeophyceae, and 33 (43%) as Rhodophyta. For all DNA sequences in this study, species-level cut off applied was ≥98% homology which depend entirely on the markers used. Three putative new records of Chlorophyta new for the Arabian Gulf were made: Cladophora laetevirens (Dillwyn) Kützing, Ulva torta (Mertens) Trevisan and Ulvella leptochaete (Huber) R. Nielsen, C. J. O′Kelly & B. Wysor in Nielsen, while Cladophora gracilis Kützing and Ulva ohnoi M. Hiraoka & S. Shimada are new records for Kuwait. For Phaeophyceae, Ectocarpus subulatus Kützing and Elachista stellaris Areschoug were new records for the Gulf and Kuwait. In the Rhodophyta, Acrochaetium secundatum (Lyngbye) Nägeli in Nägeli & Cramer, Ceramium affine Setchell & N. L. Gardner, Gelidium pusillum var. pakistanicum Afaq-Husain & Shameel and Dasya caraibica Børgesen are new records for the Gulf and Kuwait, while the red alga Stylonema alsidii (Zanardini) K. Drew is a new record for Kuwait. Several isolates identified corresponded to genera not previously reported in Kuwait and / or the Arabian Gulf, such as Porphyrostromium Trevisan, a new genus from the Bangiales, and two unidentified species for the Planophilaceae Škaloud & Leliaert. The isolates cultivated from substrata enhance understanding of the marine macroalgal diversity in the region and confirmed that the Germling Emergence Method is suitable for determining the actual diversity of a given study area through isolation from cryptic life-history phases.
Enhanced membrane fouling control in a hybrid membrane bioreactor with coarse and fine pore sponge pre-filters
Authors: Mohan S.Mariraj , Nagalakshmi S.
Published: June 2023

Membrane Bioreactors (MBR) have several advantages, but membrane fouling is a major disadvantage that prevents them from being widely used. Therefore, in the present study, the sponge was utilized as a pre-filter with coarse and fine pores in successive compartments before the membrane compartment and termed a “Hybrid-Membrane Bioreactor (H-MBR)”. In the present study, Conventional Membrane Bioreactor (C-MBR) and H-MBR were operated under similar operating conditions to evaluate the performance of H-MBR. The C-MBR experienced more frequent fouling within 60 days of operation, whereas in the H-MBR, the fouling was very low and gradual (i.e., 4.6 kPa at the end of 150 days of operation). Because of the low fouling, the need for cleaning was also eliminated for the stipulated operational period. The overall fouling rate of C-MBR and H-MBR was 5.83 kPa/d and 0.03 kPa/d, respectively. Both MBRs were good at organic pollutant removal. Because of the modification made in the present study, the H-MBR showed 14.66 times less cake layer resistance and 30 times less irreversible fouling resistance than the C-MBR. As a result, the H-MBR is effective in reducing both cake layer resistance and irreversible fouling resistance by retaining both cake-forming materials and irreversible foulants.
Evaluation of the adsorption characteristics of dissolved organic matter using granular activated carbon (GAC) and the regeneration efficiency of denitrification, Electro-Fenton, and Sono-Fenton oxidation
Authors: Joo Soobin , Lee Sangmin , Kim Heejin , Shim Intae , Kim Hyungjun
Published: June 2023

This research explored the use of a granular activated carbon (GAC) column to treat dissolved organics in Combined Sewer Overflows (CSOs), a major river pollutant. The regeneration efficiency of spent GAC was assessed utilizing three distinct methods: biological denitrification, electro-Fenton oxidation, and Sono-Fenton oxidation. Among the six organics tested, sucrose and raw sewage demonstrated the most comparable adsorption characteristics. GAC adsorption factors are multifaceted, involving pore size, surface functional groups, and competing solution substances, rather than just organic matter hydrophobicity. The biological denitrification enabled the utilization of the adsorbed organic matter on spent GAC, consequently reducing the initial NO3-N concentration from 99 mg/L to 8 mg/L over a period of 48 hours. Electro-Fenton treatment revealed marginal performance differences between SUS-SUS and Ti/Pt-Ti/Pt; however, the latter proved superior in terms of electrode stability over prolonged use. A combined strategy employing ultrasound and Fenton treatment at a frequency of 40 kHz yielded marginally higher GAC regeneration efficiency (68.5%) as compared to that at 750 kHz (67.8%). Among all regeneration techniques applied in this investigation, the Sono-Fenton method showed the highest efficiency.
Multisite algal bloom predictions in a lake using graph attention networks
Authors: Kim Nakgyeom , Shin Jihoon , Cha YoonKyung
Published: June 2023

The algal blooms caused by eutrophication is a major concern in water and aquatic resource management, and various attempts have been made to accurately predict it. Algal blooms and the factors influencing them exhibit high spatial variability depending on the characteristics of the water body and water flow. However, traditional machine learning and deep learning methods have limitations to account for the spatial interactions of various influencing factors across multiple monitoring sites. In addition, attempts to predict multiple sites simultaneously using a single model are limited. In this study, we proposed a model that considers spatial interactions and performs multisite predictions based on a graph attention network (GAT). The GAT–DNN, which combines a deep neural network (DNN) after GAT layer, was applied to forecast chlorophyll-a levels at multiple sites. The proposed model accurately captured the high variability and peak chlorophyll-a levels. Moreover, the GAT–DNN consistently outperformed two baseline DNNs in both cases. Additionally, we examined the optimal forecast horizon by comparing the performance of the model across various forecast horizons. Therefore, the proposed model can be applied to a wide range of prediction models to capture spatial interactions and obtain the benefits of performance outcomes for each site.

Published: June 2023

In order to identify the role of public art and landscape planning in the Regional Cultural Area as part of the cultural regeneration of the local community, this study analyzed the placeness and sense of place of these regions, focusing on the cases of Korea, China and Japan. The first analysis qualitatively analyzed the history and locality of each region. The framework of the second quantitative analysis is a correlation analysis of the cultural regeneration strategy, the function of public art, and the concept of landscape elements, and uses adjectives of landscape status with a specific generation in China, that is, millennials in their 20s and 30s as parameters. A questionnaire was conducted. As a result of the 1st and 2nd analysis, it was analyzed that each case exhibited a place-linked, place-dependent, place-dominant public art piece, and had a sense of place with mediating, experiential, and symbolic shared values. Traditional decorative public art form was the main form, but partly participation and intervention, and new genre public art form were shown. The sense of place perceived by the subjects was normally distributed with an average median value of 3 or higher on a Likert 5-point scale, and the difference was not large. However, among the landscape elements, there was a difference in systematicity, continuity, convenience, and originality, and a cross-section of the subjects' unconscious cognitive process could be confirmed.

Published: June 2023

This study tried to conceptually summarize the interaction characteristics of augmented and virtual reality media with Perth's symbolic idea and prove its validity through four case analyses. Therefore, the emphasis was on discourse argumentation rather than empirical research by experiment. As a result of the case analysis of this study, augmented reality showed both immedicay and hyper-medicay and virtual reality showed immedicay but not hyper-medicay. To re-analyze this into four interaction characteristics, The immedicay strategy of augmented reality was analyzed as a behavioral medium as an unfinished identity identification, and the hyper-medicay strategy was analyzed as a state medium of behavior as a possibility of thinking. The immedicay strategy of virtual reality was analyzed as the behavioral medium of reclassification, and the hyper-medicay strategy was analyzed as the state medium of behavior as a reference to objects.

Authors:   Korea Institute of Design Research Society, Jeong Hee-Jeong
Published: June 2023

In the post-COVID era, people began to think about different ways to manage these exhibition spaces. To this end, we examined the current status of selected exhibition spaces at home and abroad and conducted a survey. The results of the study showed that offline exhibitions, the traditional way of exhibition space management, are preferred to online exhibitions because they are more realistic and easier to understand, and the audience can relate to and interact with them more easily. This suggests that non-face-to-face content is not a substitute for existing offline exhibition spaces, but a complement to them. However, in response to the ever-changing digital environment, exhibition spaces should seek ways to adapt to these changes, and this warrants further research in a number of areas.
Systematization of 3D Unit Pattern Design Method for Adjustable Flexible Design Effects
Authors:   Korea Institute of Design Research Society, Ha Bong Soo
Published: June 2023

The purpose of this study was to provide a systematic design method that can harmonize the images of order and change, which can be considered as the visual characteristics of the Flexible Design Pattern(FDP). The research reviewed previous studies by grouping them according to their types and presented a design template that can harmonize visual impressions. As a result, the designmethod of FDP is summarized in threeways, startingwith the square division based onmodular and Fibonacci grid, creating order and change through the presence of symmetry manipulation in the shape design and development process, drawing visual effects while maintaining the convenience of a single unit by dividing the square into isomorphism and dimorphism, and creating unexpected intermediate forms through the overlap of large and small units. The design method that can harmonize the visual impressions of these patterns revolves around design aspects and development methods. In other words, design factors include division methods, shape design, cell combinations(cell overlap), and unit composition, while development methods include regular and irregular unit development using symmetry, among other factors that influence visual effects. The variations in impressions generated by these factors were symbolically indicated, and ultimately, a design template consisting of four adjustment directions and four combination methods was provided to facilitate the expression of the images of order and change. Furthermore, this study not only establishes a theoretical foundation for productization but also provides practical tools for design,which is expected to be useful not only for further research but also for design education.

Efficacy of Hedges in Formative Feedback on L2 Writing
Authors: Ryoo Seong Mae
Published: June 2023

In the context of cross-cultural classrooms, the exchange of feedback between teachers and students holds significant importance as a channel for dialogic communication. This study examined how international students interpreted and responded to formative feedback during their revision processes. It had two objectives: evaluating the efficacy of hedged comments in facilitating successful revisions by L2 writers and exploring students' interpretation and comprehension of hedges delivered within formative feedback. Data was collected through students’ draft and revision writing, along with retrospective interviews. The findings indicated that implicit feedback lacking clarity posed challenges, resulting in low rates of successful revisions. Students initially reacted critically to the feedback, leading to diminished confidence, motivation, and self-esteem. They also reported differences in feedback delivery compared to their previous experiences. These results emphasize the importance of writing teachers recognizing the fundamental differences in students’ academic cultures and reconstructing feedback practices for more effective communication. By adopting culturally sensitive and contextually appropriate feedback approaches, teachers can better support students in their writing endeavors and create a more conducive learning environment.
What Do Students Perceive from the Syllabus? The Importance of Syllabi to Communicate Belonging and Promote Engagement
Authors: Sunds Jessica , Rohrbach Sydney , Drais-Parrillo Alicia
Published: June 2023

Syllabi are introductions and, like first impressions, can affect one’s outlook. The current study is part of a larger evaluation of diversity, equity, and inclusion (DEI) in academic spaces; here we hoped to determine if research aligns with students’ perceptions. Prior studies suggest syllabus qualities that signal belonging and increase engagement, especially for underrepresented students. Participants rated syllabi from different years. We anticipated that 2015-16 syllabi, before DEI objectives were enacted, would have fewer identity safety cues, less emphasis on inclusion, and focus less on diversity concepts compared to 2021-22 syllabi, after DEI objectives were prioritized. The latter were rated as more inclusive, more engaging, promoting greater belonging, and having a more approachable instructor. In comparisons by group, POC and white students did not differ in their perceptions of syllabi from 2015-16 nor did traditional and non-traditional students. Perceived changes from 2015-16 to 2021-22 syllabi revealed differences by social identities. White students perceived greater changes in instructor attributes and belonging over POC students, and traditional students rated greater changes in belonging, engagement, and instructor attributes than non-traditional students. These outcomes suggest that our DEI efforts are not being perceived equally among students, which ultimately may affect student motivation and outcomes.

Metode kualitatif dengan penelitian deskriptif digunakan saat penulis melakukan penelitian ini. Instrument penelitian yang digunakan menggunakan pedoman wawancara, catatan di lapangan. Teknik yang digunakan saat menganalisis sebuah data pertama data tersebut dikumpulkan, kemudian melakukan reduksi data, hingga dapat diambil kesimpulan. Hasil dari penelitian ini adalah penulis menyatakan bahwa generasi milenial merupakan generasi yang saat ini sedang sangat rentan bila tidak mendapatkan pendidikan moral dan juga agama, bahkan kewarganegaraan yang baik dan kuat. Hal ini disebabkan generasi muda saat ini sangat rawan dalam mempercayai informasi yang belum jelas keabsahannya, atau yang biasa dikenal dengan nama hoax, bila anak tersebut tidak mampu untuk membedakan antara berita yang asli dengan yang palsu. Jika seperti ini terus menerus, maka Indonesia di masa depan akan rawan untuk terpecah belah, karena penerusnya mudah untuk diadu domba bila tidak dapat membedakan yang benar dan yang tidak.
