A new system for displaying proteins on the surface of Escherichia coli was developed using the Salmonella typhimurium outer membrane protein C (OmpC) as an anchoring motif. The C-terminal deletionfusion strategy was developed to fuse the polyhistidine peptides and green fluorescent protein (GFP) to the Cterminal of the truncated functional portion of OmpC. The polyhistidine peptides of up to 243 amino acids could besuccessfully displayed on the E. coli cell surface, which allowed recombinant E. coli to adsorb up to 34.2 μmol of Cd2+ per gram dry cell weight. The GFP could also be successfully displayed on the E. coli cell surface. These results suggest that the C-terminal deletion-fusion strategy employing the S. typhimurium OmpC as an anchoring motif provides a new efficient way for the display of large proteins on the surface of E. coli.

Plant MYB transcription factors regulate secondary metabolism, cellular morphogenesis, and plant hormone signaling pathway. MYB proteins in plants consist of two repeats of 50 amino acid residues, which are referred to as R2R3 and they interact with WD40 or basic helix loop helix (bHLH) proteins. Yeast two hybrid assay was determined whether rice MYB protein interacts with either OsTTG1, which contains a WD40 domain, or with OsGL3, which contains a bHLH domain. Among 30 OsMYB proteins, three interacted with OsTTG1 and five interacted with OsGL3. A series of MYB mutants were created to determine the MYB domain important for the interaction with OsTTG1 or OsGL3. By using the yeast two hybrid assay, we found that the R3 motif of OsMYB10 and the R2 motif of OsMYB16 were required for interaction with OsTTG1 and OsGL3 proteins, respectively.

Through the formative analysis of the traditional jokakbo, we have composed surface composition that was made by a perfect square, triangle, a weather vane type, vertical type, cintamani type, and a mixed rectangular. And we have composed 18 kinds of motif stimulants that was made by vivid tone, pale tone, and so on, and finally analyzed sensibility image, preference rate of them. The cause of composition for the sensibility image of stimulant was composed by the cause of simplicity characteristics, interesting characteristics, rigid-flexibility characteristics, and modern characteristics. And from these things, the cause of simplicity characteristics and the cause of interesting characteristics were revealed as important dimensional factors of sensibility image. The sensibility image of motif was revealed as a simple image of perfect square, a feminine image of cintamani type, a modern image of mixed rectangular. And black-white colored mixed rectangular and chromatic colored cintamani type were also revealed as an interesting image. The preference rate of motif is related with the cause of interesting characteristics and simplicity characteristics, it also has been revealed to prefer the pale tone than others. And it also has been revealed that achromatic colored mixed rectangular, cintamani type of vivid tone, perfect square and rectangular of pale tone were mostly preferred.

This study reveals the absence of standard design guidelines by region through investigation and analysis centered on public design cases by region in Jeollabuk-do and design elements that can reflect the integration, identity, and diversity of public design in each region by five regions. Through this, the following conclusions could be obtained. First, to improve the quality of street facilities in Jeollabuk-do, the design elements (design motif, color, pattern) applicable to the standard design were analyzed by dividing them into five regions. As a design motif, it was possible to extract patterns containing straight lines, sophistication, dignity, and smartness. In the Northeast region, it is comfortable with the motif of the mountain ridge reflecting geographical characteristics, and it can be extracted elements that contain warm and natural colors. In the southeastern region, patterns that reflect design elements were extracted by applying safe, lively, and peaceful colors with the design motif of curves that blend nature and agriculture. In the southwestern region, design pattern elements that highlight nature, history, and culture were extracted with various cultural assets and natural greenery as motifs. Lastly, in the Saemangeum region, the ocean flow and greenery could be used as a design motif to reflect a positive, clear, future-oriented image in the design spot zones by region. Second, based on the standard design elements (design motive, color, pattern) by region extracted for the standard design development of street facilities in each region in Jeollabuk-do, an integrated zone(Form, structure, material, color, functional element) to which regional design guidelines can be applied. Third, an integrated zone (form, structure, material, color, functional elements) was composed. In addition, design spot zones (patterns and colors in city and county units) that can contain the diversity and identity of each region were designated. By designating design spot zones (patterns and colors in city and county units) that can contain the diversity and identity of each region, standard design development plans (integrated pillars, jaywalking prevention fences, roundabouts (urban type, rural type), street trees) Eight standard designs, including protective covers, street planters, flat benches, light benches, visual media for user guidance, and parking zones for personal mobile devices) were presented.

IQGAP1은 세포 내에서 암세포화, 세포이동과 같은 다양한 기능을 수행하고 있으며, $Ca^{2+}$-비의존성 calmodulin (CaM) 결합 단백질로 잘 알려져 있다. IQGAP1내에는 IQ부위가 4 번 반복해서 나타나는데, 이 부위가 IQGAP1의 CaM 결합에 중요한 역할을 한다고 알려져 있다. 이전의 연구를 통해 4개의 IQ 부위 모두 $Ca^{2+}$/CaM과의 결합에 관여하고, IQ3와 IQ4는 $Ca^{2+}$이 결합되지 않는 상태의 CaM인 proCaM 결합에 관여 한다고 알려져 있다. 그러나, 이러한 각각의 IQ 부위와의 결합성이 CaM과 직접적인 결합인지, 아니면 다른 단백질이 매개하는 간접적인 결합인지 알려져 있지 않았다. 따라서, 본 연구에서는 IQGAP1의 각각의 IQ 부위와 CaM의 결합성을 직접적으로 알아보기 의해 in vitro에서 조사해 보았다. 그 결과, 흥미롭게도 이전의 결과와는 다르게 4개의 IQ 부위 중에서 IQ3는 의미있는 $Ca^{2+}$-비의존성 CaM결합성이 있음을 알게 되었고, IQ1는 약한 $Ca^{2+}$-의존성 CaM 결합성이 있음을 알게 되었다. 반면에, 다른 IQ 부위들은 CaM과의 결합력이 약하거나 없음을 확인하였다. 또한, 기존의 IQ 부위 이외에 IQ(2.7-3)과 IQ(3.5-4.4) 부위가 의미있는 CaM 결합성이 있음을 확인하게 되었다. 따라서, 본 연구 결과 CaM이 IQGAP1을 기존의 보고와는 다른 방식으로 조절할 수 있을 가능성이 있음을 알게 되었고, 새로운 결합 부위 동정을 통해 IQGAP1과 CaM의 결합이 미치는 생리학적인 의미를 연구할 수 있는 토대를 마련하였다.
