The purpose of this study is to suggest sleeve cap height with a satisfying wearing sensation and appearance on jackets for women in their twenties so that high-consumer demand jackets can be produced. Five experimental jackets with sleeve cap heights of [(AH/3)-1cm], [(AH/3)-0.5cm], [AH/3], [(AH/3)+0.5cm] and [(AH/3)+0.8cm] were made for 30 subjects to try on after which the subjects were then surveyed for their assessment of appearance, wearing sensation and preference. On the basis of the results, the optimum height of the sleeve cap has been proposed along with the following contents and results of this research. 1. [AH/3] [(AH/3)+0.8cm] of sleeve cap height was assessed to beof desirable appearance. 2. [AH/3] of sleeve cap height garnered a high opinion in terms of intuitive wearing sensation, while [(AH/3)-1cm] [AH/3] were the heights with overall satisfaction of intuitive and movement wearing sensations. If discomfort in the upper sleeve at 'straight arm' posture can be tolerated, the sleeve cap height can be set to [(AH/3)-1cm]~[(AH/3)+0.5cm]. 3. [AH/3] and [(AH/3)+0.5cm] were found to have a high preference among wearers, which indicated that the women in their twenties prefer a slim type of sleeve, putting appearance above wearing sensation. Consequently, [AH/3] is desirable when appearance, wearing sensation and preference are considered, [(AH/3)+0.5cm] is fit for business uniform for static duties or formal dress focused on aesthetic impression and [(AH/3)-1cm]~[AH/3] are desirable for work clothes when considering active duties.

The aromatic hydrocarbon receptor (AhR) is a cytosolic protein that binds the environmental pollutant, dioxin. The liganded AhR translocates into the nucleus where it heterimerizes with a constitutive nuclear protein, AhR nuclear translocator (Arnt). The N-terminal regions of both AhR and Arnt contain basic helix-loop-helix (bHLH) and Per-AhR-Arnt-Sim (PAS) motifs that are required for DNA binding, dimerization, and ligand binding whereas the C-terminal regions of both AhR and Arnt contain transactivation domains. Here, results from the mammalian two-hybrid system indicate that Arnt can make a homodimer but AhR cannot. In the presence of dioxin, the interaction between AhR and Arnt is stronger than that of the Arnt homodimer, suggesting that Arnt prefers to make a heterodimer with the liganded AhR rather than a homodimer. Transfection analyses using the GAL4-driven reporter system suggest that AhR's N-terminal region represses its own transactivation domain, as well as exogenous transactivation domains such as Sp 1 and VP16. Interestingly, the repressed transactivation domains of AhR are activated by ligand-dependent heterodimerization with Arnt. These observations suggest that heterodimerzation with Arnt is necessary not only for DNA binding but also for activation of the repressed transactivation capability of AhR.

전사개시전 복합체(preinitiation complex)에서 단백질간의 상호작용을 연구하시 위해 zero-Iength croessinking방법을 이용하였다. DNA template가 결합한 금속 지지체를 이용하여 in vitro에서 전사개시전 복합체를 형성시키고, 이렇게 만든 복합체를 1-ethyl-3-(3-dimethylaminopropyl) carbodlimide(EDC)로 croessinking시켰다. $\beta$-mercaptoethanol를 첨가하여 croessinking반응을 멈추게 한 다음, EDC로부터 전사개시전 복합체를 분리하였다. TBF,TFIIB,GAL4-AH등으로 구성된 전사개시전 복합체에 이러한 방법을 적용함으로써 TBF가 GAL4-AH,TFIIB와 각각 직접적으로 결합하고 있음을 규명하였다. 반면에 GAL4-AH와 TFIIB가 croessinking된 산물은 확인할 수 없었다. 이러한 결과들은 GAL4-AH,TFIIB,TBP,DNA로 구성된 전사개시전 복합체에서 GAL4-AH는 TFIIB와 안정적인 결합을 하고 있지 않음을 암시한다.

This study was designed to examine the effects of Allium hookeri (AH) on plasma blood glucose and fat profile levels in diabetic rats. Diabetes mellitus was induced in male Sprague-Dawley rats through injection of streptozotocin (STZ) dissolved in citrate buffer into tail veins at a dose of 45 mg/kg of body weight. Sprague-Dawley rats were then fed for 4weeks, with the experimental groups receiving a modified diet containing 5% or 10% powder derived from AH roots. The experimental groups were divided into four groups, consisting of a control group, STZ-control group, and diabetic fed with AH 5% & 10% treated groups. Rats' body weights, blood glucose, total cholesterol, HDL-cholesterol, triglyceride (TG), and free fatty acid (FFA) values in plasma were measured along with hematocrit (Hct) values and aminotransferase activities. Body weight losses were observed in the STZ-control group, whereas the STZ-AH group of diabetic rats gained weight. There was a significantly decrease in brain weight of the STZ-AH group but no significant differences in kidney and liver weights of the STZ-AH 5% & STZ-AH 10% groups compared to the STZ-control group. Blood glucose was significantly reduced in the STZ-AH 5% & STZ-AH 10% diabetic groups. There were no significant differences in total cholesterol and TG levels among the diabetic groups. HDL-cholesterol significantly increased while FFA significantly decreased in the STZ-AH 5% & STZ-AH 10% diabetic groups. The Hct level of the STZ-AH group was lower than that of the STZ-control group. Aspartate aminotransferase activity was significantly reduced in the STZ-AH 5% & STZ-AH 10% diabetic groups. These results indicate that supplementation with Allium hookeri root may have beneficial effects on diabetic complications as a potential therapeutic candidate.

Objectives: This study aimed to evaluate the effects on bone repair of different concentrations of mineral trioxide aggregate (MTA) added to AH Plus. Materials and Methods: Bone tissue reactions were evaluated in 30 rats (Rattus norvegicus) after 7 and 30 days. In the AH + MTA10, AH + MTA20, and AH + MTA30 groups, defects in the tibiae were filled with AH Plus with MTA in proportions of 10%, 20% and 30%, respectively; in the MTA-FILL group, MTA Fillapex was used; and in the control group, no sealer was used. The samples were histologically analyzed to assess bone union and maturation. The Kruskal-Wallis and Mann-Whitney tests were performed for multiple pairwise comparisons (p ≤ 0.05). Results: At the 7-day time point, AH + MTA10 was superior to MTA-FILL with respect to bone union, and AH + MTA20 was superior to MTA-FILL with respect to bone maturity (p < 0.05). At the 30-day time point, both the AH + MTA10 and AH + MTA20 experimental sealers were superior not only to MTA-FILL, but also to AH + MTA30 with respect to both parameters (p < 0.05). The results of the AH + MTA10 and AH + MTA20 groups were superior to those of the control group for both parameters and experimental time points (p < 0.05). Conclusions: The results suggest the potential benefit of using a combination of these materials in situations requiring bone repair.

It seems obvious that the spatial information of existing architectural heritage will be re-structured utilizing BIM technology. In the future to be able to implement such task, a new system of classification of spatial information, which fit to the structural nature of architectural heritage is necessary. This paper intend to suggest the conceptual model that can be the base of establishing new classification system for architectural heritage. For this study we reviewed researches related to classification system of architectural heritage (CS-AH) and BIM based architectural heritage (BIM-AH), first. As a result, we found that CS-AH is focused on building elevation and type, and BIM-AH is biased on the Library and Parametric Modeling. Second, we figured out a relationship between the CS-AH and BIM-AH. From this analysis, we found that BIM-AH is biased on Library and Parametric since the building elevation and type was focused on CS-AH. This review suggests a potential of the 3D CS-AH to expand the range of research for BIM-AH. At last, we suggest the three concept of classification are: 1)horizontality-accumulation relationship, 2)structure-infill relationship, 3)segment-member relationship. These three concept, together as one system of classification, could provide useful framework of new classification system of spatial information for architectural heritage.

라디오 방송은 무선 통신 매체로써 가장 오래된 방송 역사를 가지고 있다. 최근에는 다매체의 등장과 인터넷의 발달로 위상이 과거에 비해 추락하였다. 하지만 다양한 매체 속에서도 라디오가 가지는 특수성이 있음은 분명한 사실이다. 따라서 이에 대한 청취자들의 수요가 꾸준히 존재하기에 본 논문에서는 라디오만이 갖는 오디오의 특성을 살려 청취자들의 흥미를 유발할 수 있는 멀티 채널 오디오 시스템을 제안한다. 이를 통해서 기존의 라디오 시스템에서 탈피하여, 청취자들이 선택적으로 오디오를 청취하는 시스템을 구축하고자 한다.

코로나(COVID-19)로 인해 언택트(Untact) 방송이 활성화된 현 시점에서 기존 방송의 형태는 나날이 변화하고 있다. 특히 1인 미디어 대한 관심이 급증하게 되면서 1인 방송 체제가 전통적 미디어뿐만 아니라 대중에게까지 많은 영향을 미치며 하나의 트렌드로 자리 매김하게 되었다. 따라서 본 연구는 1인 방송의 특성과 시스템 설계를 바탕으로 최소한의 장비를 사용하여 양질의 스트리밍 서비스를 제공하기 위한 1인 방송 시스템을 구축하고자 한다.
