Objectives : The purpose of this study is to investigate which system the FanQie notation of "Taisu(太素)" followed by comparing FanQie notation appearing in "Taisu", with the Sound button(聲紐) and Rhyme system(韻類) of the FanQie notation appearing in the "Qieyun(切韻)" system phonology book and "Guangyun(廣韻)". Methods : Followed by organizing the FanQie list in "Taisu", in comparing this list with the top and bottom characters of FanQie in the "Qieyun" system phonology book and "Guangyun", this study explores the similarity of the system after noting the Sound button and the Rhyme system. Results & Conclusions : 1. Compared to FanQie of "Taisu" with that of "Qieyun" system, the Sound button and Rhyme system were 61.54% identical, and when comparing FanQie of "Taisu" with that of "Guangyun", the Sound button and Rhyme system were 55.45% identical. 2. Comparing FanQie top and bottom letters themselves of the "Taisu" and "Qieyun" system, of the 217 FanQie sound notation Chinese characters, FanQie top and bottom letters of 18 characters were the same, accounting for 8.29%, and when compared to the "Taisu" with the FanQie top and bottom characters of "Guangyun", 15 FanQie top and bottom characters were the same, accounting for 6.91%. 3. Of the total 11,500 characters in "Qieyun", the ratio of FanQie notation Chinese characters in "Taisu" was 1.89%, and among them, nine characters came out in "Taisu" FanQie notation while there was none in "Qieyun". This accounted for 4.15% of 217 FanQie notation sound Chinese characters in "Taisu", demonstrating that this represented a relatively high ratio. 4. Conclusionally "Taisu" was more closely related to "Qieyun" system phonology book than "Guangyun" in FanQie notation, and there is also a possibility that Yang Shangshan has created some FanQie notation by himself or additionally referred to other phonology books that are not "Qieyun" system phonology book.

This study focused on evaluating the phytoextraction of heavy metals (Co, Pb, and Zn) induced by bioaugmentation of button mushroom compost (BMC) in Helianthus annuus (sunflower). When the potential ability of BMC to solubilize heavy metals was assessed in a batch experiment, the inoculation with BMC could increase more the concentrations of water-soluble Co, Pb, and Cd by 35, 25, and 45% respectively, compared to those of non-inoculated soils. BMC-assisted growth promotion and metal uptake in H. annuus was also evaluated in a pot experiment. In comparison with non-inoculated seedlings, the inoculation led to an increase in the growth of H. annuus by 27, 25, and 28% in Co-, Pb-, and Zn-contaminated soils, respectively. Moreover, enhanced accumulation of Co, Pb, and Zn in the shoot and root systems was observed in inoculated plants, where metal the translocation from root to the above-ground tissues was also found to be enhanced by the BMC. Evidently, these results suggest that the BMC could be effectively employed in enhancing the phytoextraction of Co, Pb, and Zn from contaminated soils.

This study investigates the merits of incorporating augmented reality in mobile games and proposes a mobile game application that combines augmented reality technology with gaming. The proposed study postulates that augmented reality technology can be employed for developing games on smartphones. The proposed application involves the implementation of a 3D virtual object in the real world by incorporating a target image. The proposed application also employs an intuitive interface with simplified manipulation based on touch, and allows players to collect and combine items for acquiring new items, thus making it elementary to pass the game stages. Furthermore, a ranking system has been introduced in the proposed application for enhancing the amusement factor of the game. The novelty of the proposed application lies in the fact that the virtual button function has been employed for combining physical and virtual objects while playing the game, without incorporating location-based services.

The objective of this study is to quantitatively incorporate user observation into usability evaluation of mobile interfaces using monitoring techniques in first- and third-person points of view. In this study, an experiment was conducted to monitor and record users' behavior using Ergoneers Dikablis, a gaze tracking device. The experiment was done with 2 mobile phones each with a button keypad interface and a touchscreen interface for comparative analysis. The subjects included 20 people who have similar experiences and proficiency in using mobile devices. Data from video recordings were coded with Noldus Observer XT to find usage patterns and to gather quantitative data for analysis in terms of effectiveness, efficiency and satisfaction. Results showed that the button keypad interface was generally better than the touchcreen interface. The movements of the fingers and gaze were much simpler when performing given tasks on the button keypad interface. While previous studies have mostly evaluated usability with performance measures by only looking at task results, this study can be expected to contribute by suggesting a method in which the behavioral patterns of interaction is evaluated.

The purpose of this study is to compare assessment techniques for Korean characters entry methods of mobile phones. This study was performed based on survey of relevant existing studies. The assessment techniques were classified into three: 1) predicting entry time using conceptual models such as Fitts' law, Hick-Hyman's law and KLM-GOMS model (conceptual model); 2) counting the number of pressing button(number of pressing button); and 3) measuring performance or rating subjective measures using real mobile phones(real mobile phone). The comparison revealed that the assessment results were different depending upon the techniques used. The results from the conceptual model using only Fitts' law and the number of pressing button were opposite to those from techniques of the real mobile phone and conceptual model using Fitts' and Hick-Hyman's laws. Based on this result and suggestions provided by the literature, it is recommended that for more precisely assessing interfaces of mobile phones such as Korean characters entry method, real mobile phones be used instead of the conceptual models.

True aneurysms of the coronary artery after aortic root replacement in Marfan syndrome patients are very rare. An anomalous origin of the right coronary artery (RCA) from the left sinus of Valsalva adds complexity during aortic root surgery. We present a case of a 37-year-old male patient with Marfan syndrome who had an RCA anomaly and a 4.5-cm true aneurysm of the common coronary button 14 years after a previous Bentall procedure. A redo Bentall operation and hemi-arch replacement were successfully performed. The anomalous origin of the RCA from the left sinus of Valsalva was safely divided and anastomosed as separate coronary buttons to the prosthetic composite valve graft. To prevent coronary button aneurysms after aortic root surgery in Marfan patients, the coronary buttons and the corresponding side holes on the prosthetic graft must be reduced to the maximum possible extent.

Objective: The aim of this paper is to inquire into the influences form factors and control types affect a search time and comfort at list menu of full touch phone. Background: Various studies have been proceeded that are related to the optimum touch area for enhancing usability of control and legibility in mobile touch device. In the environment of list menu which is widely used to provide various information effectively, however, not only comprehensive consideration for legibility and control is to be seek but also research for control type which is to scroll a list. Method: This study executed form factor experiment to inquire into the influence that font size, height of row and fixed area affect searching time and comfort in the while information processing even if the information on the list is unsorted in alphabetical order. Among the result of form factor experiment, control type experiment was executed by selecting shortest performance time, highest legibility comfort and control comfort. Control type experiment was implemented to figure out the influence which existing flicking type, scrolling bar type, newly established button page type and button raw types affect performance time and subjective comfort depending on location of the information. Results: Font size 12pt, height of row 7mm and fixed area 15mm was shortest performance time and got highest comfort and legibility score in form factor experiment. A Button page which was newly proposed type was shortest performance time and got highest comprehensive comfort in control type experiment. Conclusion: Form factor experiment showed similar results with the study through reading a long passage of character or controlling a grid icon type. However, height of row turned out to affect not only touch area for control but also legibility by ruling space between the lines. Button page type which was newly proposed showed shortest performance time and got highest comprehensive comfort. Because Button page type needs few finger movements than other control types and implements search in the fixed form, unlikely other type which list keeps moving. Application: This study should be applied in deciding form factors and control type for scroll when designing a list menu of full touch phone.
