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.

A zero-Iength croessinking procedure for studying protein-protein interactlons in preinitiation complex has heen developed. Preinltiadon complexes were assembled with immobilized DNA templates coupled to metal beads. Pudfied complexes were dIrectly crosslinked by 1-ethyl-3.(3-dimethylaminopropyl)carbodlimide (EDC). The reaction was stopped by addition of $\beta$-mercaptoethanol, and the complexes were isolated from EDC immedIately. An appllcatlion of this method with a preinltlation complex assembled with TBP, TFIIB, and GAL4-AH demonstrated that ThP dIrectly interacts with GAL4-AH and TFIIB in the prelnitlatlon complex. However, croeslinked produd between GAL4-AH and ThilB was not observed. These resutts lndlcate that GAL4-AH does not stably Interact with TFIIB In the GAL4-AH-TFIIB-TBP-DNA prelnitlatlon complex.

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.
