Generally, operators suffer much difficulty in manipulating micro-nano-sized objects without assisting of human interface, due to the scaling effects in micro/nano world. Thus, the micromanipulation system based on the teleoperation techniques enables operators to manipulate the micro objects easily by transferring both human motion and manipulation skills to the micromanipulator. In teleoperated microassembly, it is necessary to provide a useful user interface for facilitating micro assembly task executed by human operators. In this paper, Intelligent User Interface (UI) for teleoperated microassembly is proposed. The proposed intelligent UI improves task performance by teleoperated micromanipulation as well as guides operators to succeed in desirable ...

Information Systems (IS) auditing has been know to be helpful in developing optimal IS and managing information resources successfully. The public sector of Korea has witnessed the rapidly growing demand for IS auditing. However, there is a dearth of research that evaluate the effects of IS auditing. This study assesses the impacts of IS auditing based on a process perspective. In order to evaluate the effects objectively and properly, the current study collected empirical data from 58 firms. This stuuy confirmed that IS auditing was a very effective tool for successful IS implementation. The results show that IS auditing improves “project management”, “support”, and “engineering” practices while it does not make any impact on “contract” practice. In general, IS auditing has a tremendous impact on facilitating organization’quality improvement efforts.

Background: Muscle weakness and impaired trunk muscle control are common in stroke patients. The bridging exercise (BE) is generally used for trunk stabilization and improving the overall function of stroke patients. The effectiveness of the BE with hip adductor contraction (BEHA) in facilitating trunk muscle activation has been well studied in healthy adults. However, the impact of BEHA in sub-acute stroke patients has not yet been investigated. Objects: The purpose of this study was to determine the effects of BEHA on the electromyography (EMG) activities and the asymmetry of the rectus abdominis (RA), external oblique (EO) and internal oblique (IO) abdominal muscles. Methods: Twenty participants with sub-acute stroke (11 males and 9 females) were recruited. Each participant was asked to perform bridging exercises for five seconds under three different conditions: BE in a neutral position (BEN), BEHA with a large ball (BEHAL) and BEHA with a small ball (BEHAS). The EMG amplitudes of the bilateral RA, EO and IO and the asymmetry of the EMG activity between the sound and affected sides were compared among the conditions. The significance level was set at ${\alpha}=.05$. Results: The EMG activities of RA, EO and IO were significantly greater during BEHAL and BEHAS than during BEN (p<.05); the asymmetry of the RA, EO and IO decreased significantly during BEHAL and BEHAS compared to BEN (p<.05). However, no measured variables showed any significant differences between BEHAL and BEHAS (p>.05). Conclusion: This study compared the EMG activities of the RA, EO and IO on both sides and the asymmetry of the RA, EO and IO during BEN, BEHAL and BEHAS. Our findings suggest that BEHA was more effective for individuals with hemiplegic stroke at facilitating and normalizing abdominal muscle control than BEN.

This study was purposed to investigate the antioxidative effects, the enzyme activity of the alcohol metabolizing and melanin production of Maesil(Prune mume). The antioxidant activity of Maesil(Prunu mume) was analyzed by measuring thiobarbituric acid reactive substances(TBARS value) and electron donating ability. And we investigated the changes of alcohol dehydrogenase(ADH) and acetaldehyde dehydrogenase(ALDH) activity by measuring the maximum absorbency at 340nm in vitro and human study. The inhibitory effects of Maesil were investigated in vitro and in B-16mouse melanoma cells on melanin biosynthesis that is closely related to hyperpigmentation. The antioxidant activities for TBA values were 29.65% in ascorbicacid, 45.35% in BHT, 15.99% in extract of dehydrated maesil flesh(EDMF) and 25.00% in extract of dehydrated maesil juice(EDMJ). The electron donating abilities by DPPH were 96.69% in ascorbic acid, 77.82% in BHT, 34.25% in EDMF, and 42.99%in EDMJ. Electron donating abilities by DPPH in the presence of 0.02% EDMF and EDMJ were 53.21% and 59.19% respectively. Facilitating rates of ADH activity were 137.92, 131.58, 152.96, 218.70, 111.76, and 144.27% in maesil juice, 5, 10, and 15% GMT, and 0.5 and 1.0% aspartic acid, respectively. ALDH activity increased in the order of Maesil juice > ALDH > GMT > aspartic acid, and facilitating rate of ALDH activity in Maesil juice was the highest at 976.44%. Maesil extracts inhibited tyrosinase activity that converts dopa to dopachrome in the biosynthesis process. B-16 cells treated by Maesil extracts showed that the viability was over 80%. Maesil and maesil products in vitro and B-16 cells inhibited melanin production significantly.

The forest landscape has been considered to be one of the most beneficial factors, in regard to facilitating the therapeutic effects of the forest environment. The aim of this study was to review the preceding literary works on the correlation between forest landscape and its therapeutic effects and to ponder on key factors of forest landscape that promotes therapeutic results on people's psychological and physiological responses. Literature found in domestic research databases was analyzed and examined in accordance with the 'Preferred reporting items for systematic reviews and meta-analyses(PRISMA)' process. Six papers out of 1,890 were selected as key literature to support the connection. The quality of forest landscape was found to be an integral environmental factor in determining the healing effects of forests. In particular, several factors, including forest types, aquatic elements within the forest landscape, forest-use density and aesthetic elements of forest landscape were found to be crucial for enhancing the therapeutic effects on people's wellbeing. Despite the limited sample groups in the analyzed literature, the results offered a significant insight in supporting the healing effects of forests. Further studies on this subject are required to provide more scientific data for verifying the quality of the therapeutic effects of forests.

This study is designed to figure out the effects of major selection motivation on career efficacy and major satisfaction of college students majoring in culinary and foodservice management. To achieve this purpose, a survey was carried out to 209 college students. The findings showed that their major selection had a significant effect on their career efficacy and major satisfaction. But the mediating effect of their career efficacy as a mediator - which improves their major selection and major satisfaction - was partially adopted. Consequently, their internal and external participation motivation for their major selection is a facilitating mechanism to maximize their major satisfaction, and it is necessary to limit the use as a mediating variable of their career efficacy.
