Background: Normal-weight obese women have a normal weight with relatively low muscle mass resulting from high body fat. We aimed to investigate the effects of core exercise on body composition, abdominal muscle thickness, trunk muscular endurance, and psychological factors in normal-weight obese women. Design: One group pre-, mid-, and post-test design. Methods: A total of 20 normal-weight obese women were recruited voluntarily. Core exercises were performed for 30 minutes, three times a week for 4 weeks. InBody measurements, ultrasound imaging, and clinical tests were used to assess body composition, abdominal muscle thickness, trunk and core muscular endurance, and psychological condition(satisfaction with appearance and self-esteem). The dependent variables were measured three times: before the intervention (pre-test), 2 weeks after the intervention (mid-test), and 4 weeks after intervention (post-test). One-way repeated measures ANOVA and Friedman test were used for statistical analysis. Results: Although there was no change in the body composition (p>0.05), thickness of the transversus abdominis and internal and external oblique muscles, endurance of the trunk flexors and extensors and core muscles, and psychological condition showed significant differences after the intervention (p<0.05). Conclusion: Our findings will help develop exercise programs for normal-weight obese individuals that utilize the beneficial effect of core exercises.

The sequences of the D1/D2 region of 26S rDNA from seven Sporobolomyces species, Bensingtonia subrosea, and Rhodosporicium toruloides were determined and compared with those from representatives of the genera Leucosporidium, Rhodosporidium, Rhodotorula, and Sporidiobolus. The five species of Sporobolomyces analyzed were distantly related to a monophyletic clade consisting of species of Sporidiobolaceae and Sporobolomycetaceae. Sporobolomyces falcatus was found to be closely related to Tremella exigua. The members of Sporidiobolaceae and Sporobolomycetaceae were divided into four groups. Group 1 was composed of Leucosporidium scottii and two Rhodotorula species, and group 2 contained three Rhodotorula species. Group 3 was designeate as the Sporobolomyces/Sporidiobolus core group, as it contained Sporidiobolus johnsonii, the type species of Sporidiobolus and the teleomorphic state of Sporobolomyces salmonicolor (the type species of Sporobolomyces). Group 4, named the Rhodotorula/Rhodosporidium core group, included Rhodosporidium toruloides and Rhodotorula glutinis, the type species of the genera Fhodosporidium and Rhodotorula, respectively. The four groups were differentiated on the basis of their physiological characteristics including the assimilation of D-glucosamine, glucuronate, 2-keto-gluconate, L-arabinitol, raffinose, methyl-$\alpha$-glucoside, and satrch. The taxonomy of the genera Leucosporidium, Rhodosporidium, Rhodotorula, Sporidiobolus, and Sporobolomyces will require a major revision when more data becomes available.

Critical thinking includes creative thinking, open-mindedness, inquisitiveness. Critical Thinking Disposition was significantly higher in experimental group that was enhanced by the scenario-based learning contents than that of the control group(t=4.102, p<.001). Problem Solving process was significantly higher in experimental group that was enhanced by the scenario-based learning contents than that of the control group(t=5.082, p<.001). However, there was no significant difference between the two groups in Clinical Competence(t=2.646, p=.009). But experimental group was significantly higher score than that of the control group score decreased. These results support that the implementation of a scenario-based learning contents need to be continued as an effective educational material but we need more research to establish how this can be effectively implemented in a students' practicum.

This study was performed to investigate the effect of kangaroo care on body weight, physiological responses and behavioral states in premature infants. The subjects were 32 premature infants, fifteen for the kangaroo care group and seventeen for the control group, who hospitalized in a neonatal intensive care unit at a university-affiliated hospital. The kangaroo care was applied 8 times during the twenty five days with 40 minutes for each session. The kangaroo care provides the skin-to-skin contact during which a premature infant wearing a diaper and a hat is placed on its mother's chest. As for the measures, body weight was measured everyday. The levels of epinephrine, norepinephrine and 17-OHCS were measured twice, before beginning the first intervention and after finishing the last intervention. While each session of the care is undergoing, such physiological responses were measured periodically as heart rate, respiration rate, oxygen saturation, core temperature and skin temperature. The results were as follows : 1. The weight gain was significantly greater in the kangaroo care group than that in the control group during the period of performing the kangaroo care. 2. No significant difference was revealed between the two groups in heart rate, respiration rate, oxygen saturation and core temperature. The kangaroo care group also showed significant increases in the skin temperature. 3. The differences in the levels of epinephrine, norepinephrine and 17-OHCS were not significant between the kangaroo care and the control groups. The level of norepinephrine in the two groups was significantly increased over time. 4. Sleep pattern changed significantly in the kangaroo group from a very restless sleep to a very quiet sleep. These results suggest that kangaroo care is an effective nursing intervention for premature infants in gaining weight, achieving stable physiological responses and facilitating a quiet sleep.

Safety, livability, and efficiency are the three prominent problems of tall buildings, which are also the severe challenges to designers. We proposed the idea of building the sky town to solve these problems, which can be summarized in two sentences, one is tall building multi-storised, and another one is vertical facilities municipal-infrastructurised. The tall building can be horizontally cut into several multi-storey buildings by some large platforms. The platform extends a certain width to block the fire from spreading. Tall buildings are connected together as a group. One of them is a traffic core, which is used for vertical transportation and MEP. It connects to traffic center such as metro, while most of the other tall buildings' cores can be very much released, so as to achieve maximum efficiency of floor usable area and to give good traffic organization. By combining traffic core, platforms, and multi-storey buildings' inner traffic, a transportation network is formed. Finally, we refer to the design of Raffles City Chongqing to make a sketch of sky town.

The convergent synthetic strategy for the emissive dendrimers having the chromophore at core via the coppercatalyzed 1,3-dipolar cycloaddition reaction between alkyne and azide was described. 2,7-Diazido-9,9-dioctyl-9H-fluorene, designed to serve as the core in dendrimer, was stitched with the alkyne-functionalized Frechettype and PAMAM dendrons by the click chemistry leading to the formation of the corresponding fluorescent dendrimers in high yields. The preliminary photoluminescence studies indicated that 2,7-diazido-9,9-dioctyl-9H-fluorene showed no fluorescence due to the quenching effect from the electron-rich ${\alpha}$-nitrogen of the azido group but the dendrimers fluoresced due to the elimination of the quenching through the formation of the triazole ring.
