In many urban cities, mixed-use development is becoming increasingly essential for the creation of an attractive and sustainable environment that promotes economic vitality, social equity and environmental quality. Due to the differences in scale, scope and intent, certain aspects within the project delivery process of mixed-use are not the same as "conventional" single-use projects. The objective of this paper is to highlight these aspects. Two cases in Southeast Asia serve to illustrate the uniqueness and challenges of mixed-use. In conclusion, the differences between mixed-use and single-use are evident in terms of the diversity of team members, the necessity of multiple market analyses, and a multi-layer (versus single-source) financing structure. Finally, issues concerning ownership tangles, land assembly, planning and application procedures, investment criteria of institutions have been identified as major pitfalls.

Chlorella is an attractive potential food source because it is high in protein and other essential nutrients; when dried, it is about 45% protein, 20% fat, 20% carbohydrate, 5% fibre, and 10% minerals and vitamins. It has been widely used as a well-being food. We investigated the quality characteristics of cookies prepared after addition of various concentrations of chlorella powder (0%, 1%, 3%, and 5%, all w/w) as a substitute for flour. In this study, as chlorella powder concentration rose, decreases in the moisture content, pH, L, a and b value became evident. The spread factor and hardness of the cookies slightly increased after the addition of chlorella powder. Sensory evaluation scores in terms of color, flavor, and texture were statistically very similar, but taste and overall acceptability scores were lower than those of the control. The result of this study showed that the quality of the cookies with the addition of 1% chlorella powder was the best in terms of its taste, flavor, texture, and sensory properties.

Ultrasonic has been proposed as an attractive means of detecting bone loss. There have been several commercial ultrasound devices developed for measuring the heel to predict fracture at other bones. However, these devices select only single point of heel bone as measurement site. It causes poor assessment of bone quality due to the error of transducer positioning. In an effort to improve current ultrasound systems, we evaluated the linear scanning method which provides better prediction of bone quality and an accurate image of bone shape. The system used in this study biaxially scans a heel bone using automated linear scanning technique. The results demonstrated that the values of ultrasound parameters varied with different positions within bone specimen. It has been also found that the linear scanning method could better pre야ct bone quality, eliminating the error of transducer positioning.

According to the Global Retail Development Index (GRDI) published by A.T. Kearney (2012), India is the $5^{th}$ most attractive retail destination in the world. The retail industry in India has been largely fragmented with small businesses dominating the retail landscape, with very few large players having multiple retail outlets. However, in the last few years, the industry has witnessed a significant growth in the number of large retailers having a chain of outlets across the country. This growth in the organised retail sector has driven primarily by large Indian retail organisations and conglomerates. With the government reducing the restrictions on foreign participation in Indian retail business by increasing the FDI cap on both single and multi-brand retail outlets, the industry is likely to see an explosive growth in the organised retail sector which accounts for only 8 percent of the total industry. With more foreign retailers poised to enter into the country, one of the key issues that the industry may face is finding the right quality of manpower. Literature suggests that in an industry which is characterised by players offering similar kinds of product assortments at similar price levels, success would be governed by the quality of service, which entails employees having the right skills and attitudes for offering quality service. Therefore, the two key issues that may be of importance for retailers are levels of skills and the motivation of the employees. However, according to the National Skill Development Corporation (NSDC, 2009), a significant skill gap exists in the industry, which may widen further in the years ahead, leading to greater challenges for organisations. This paper highlights some of the challenges and issues which characterise the industry in India, and suggests how companies could look at these challenges and seek ways to overcome these challenges.

The purpose of this paper is to investigate in resources of natural recreation forest(RNRF) developed both publicly and privately in order to answer the research question: what are the differences in RNRF development between public and private developers. After reviewing the literature, the developer´s decision-making and motivation of investment, and the planning process of natural recreation forest, We constructed the conceptual framework and have formulated the hypothesis of this research. We had obtained data through a questionnaire, which surveyed of 625 visitors at 9 of the 72 natural recreation forests in Korea in 1999, We have analyzed the data using the mean difference test and logistic regression method. We found that 1) the overall quality of resource elements in RNRF has been development excellent except for the sociocultural element of recreational resources, and public recreation forest have been of higher quality than that fo private development, 20 in bivariate analysis, all the variables on quality of RNRF by public developers have turned out to be better than those of private ones, 3) in multivariate analysis, such variable as valley and water, forest and wildness area, wild life, and landscape have been statistically significant at one percent level, 4) the higher the value of valley and water, the higher the probability of public development, while the higher the value of other variables excluding water and valley, the more likelihood the recreational forest is developed by a private developer, and 5) forest and wildness area has been turned out to be the most important independent variable in contributing to the value of dependent variable. The research results suggest that 1) the differences in the quality of resource elements in RNRF developed by public and private body be considered in the planning and design process in order to develop diverse activities to make use of the resource potential, and 2) considering the resource characteristics of private natural recreation forest and the motivation of private developers, private natural recreation forest will possibly be more dynamic and dynamic attractive areas. It is recommended that the difference in the degree of visitor´s satisfaction between public and private development be examined.

In this paper, a novel Active Voltage Quality Regulator (AVQR) topology with a thyristor rectifier and an adaptive dclink voltage control strategy are proposed. The proposed AVQR can efficiently mitigate the long duration variations (e.g. undervoltages/overvoltages), voltage imbalances and voltage harmonics. Compared with conventional AVQRs, it can regulate the load voltage very well with a much lower dc-link voltage. This is accomplished by replacing the diode rectifier with a thyristor rectifier. Moreover, its dc-link voltage can vary with the deviations of the supply voltage through the proposed adaptive dc-link voltage control strategy. All of these contribute to its significantly higher efficiency for online operating, which is very important and attractive for many applications. The proposed topology and control strategy are theoretically analyzed in detail. Simulation results are also provided in the paper. Finally, the feasibility and effectiveness of the proposed method are verified by means of experimental results from a 2kVA prototype. Both of the simulation and experimental results show that the proposed AVQR can achieve a much higher efficiency and similar regulation performance when compared with the conventional ones.

In this paper we designed the motor control IP Core and evaluate its quality from the viewpoint of IP reuse. The most attractive merit of this methodology, so called IP-based hardware design, is hardware reuse. Although various vendors designed hardware with the same specification and got the same functional results, all that IPs is not the same quality in the reuse aspect. As tremendous calls for SoC have been increased, associated research about IP quality standard, VSIA(Virtual Socket Interface Alliance) and STARC(Semiconductor Technology Academic Research Center), has been doing best to make the IP quality evaluation system. And they made what conforms to objective IP design standard. We suggest the methodology to evaluate our own designed motor control IP quality with this standard. To attain our goal, we designed motor control IP that could control the motor velocity and position with feedback compensation algorithm. This controller has some IP blocks : digital filter, quadrature decoder, position counter, motion compensator, and PWM generator. Each block's functionality was verified by simulator ModelSim and then its quality was evaluated. To evaluate the core, We use Vnavigator for lint test and ModelSim for coverage check. During lint process, We adapted the OpenMORE's rule based on RMM (Reuse Methodology Manual) and it could tell us our IP's quality in a manner of the scored value form. If it is high, its quality is also high, and vice versa. During coverage check ModelSim-SE is used for verifying how our test circuits cover designs. This objective methods using well-defined commercial coverage metrics could perform a quantitative analysis of simulation completeness. In this manner, We evaluated the designed motor control IP's quality from the viewpoint of reuse. This methodology will save the time and cost in designing SoC that should integrate various IPs. In addition to this, It can be the guide for comparing the equally specified IP's quality. After all, we are continuously looking forward to enhancing our motor control IP in the aspect of not only functional perfection but also IP reuse to prepare for the SoC-Compliant motor control IP design.

In digital broadcasting, services such as digital satellite TV, cable TV and digital terrestrial TV, several video programs are compressed by MPEG-2, and then simultaneously transmitted over a conventional CBR (Constant Bit Rate) broadcasting channel. In this paper, we propose a joint quality control scheme to be able to accurately control the relative picture quality among the video programs, which is achieved by simdt;,nL'Ously controlling the video encoders to generate the VBR (Variable Bit Rate) compressed video streams. Our quality control scheme can prevent the video buffer overflow and underflow by total target bit allocation process, and also exactly control the relative picture quality in terms of PSNR (Peak Signal to Noise Ratio) between some programs requiring higher picture quality and others by rate-distortion modification. Furthermore we present a rate-distortion estimation method for MPEG-2 video, which is base of our joint quality control, and verify its performance by experiments. The most attractive features of this estimation method are as follows: 1) computational complexity is low because main operation for the estimation is to calculate the histogram of OCT coefficients into quantizer; 2) estimation results are very accurate enough to be applied to the practical MPEG-2 video coding applications. Simulation results show that the proposed joint quality control scheme accurately controls the relative picture quality among the video progran1s transmitted over a single channel as well as provides more consistent and higher picture quality than independent coding scheme that encodes each program independently.

Little information exists on how wash operations affect water quality, or the efficacy of sanitizers on vegetable quality and microbial reduction in fresh-cut carrot shreds. This study evaluated the efficacy of chlorine and ozone in reducing microbial loads and maintaining vegetable quality of carrot shreds. Fresh-cut carrot shreds were teated with various chlorine and ozone concentrations for differing times. The samples were then centrifuged to remove excess water, packaged in film, and stored at $5^{\circ}C$. The result indicated that varying the ozonated water wash time affected microbial growth the development of unpleasant odors, color, and the overall quality of carrot shreds. Ozonated water washing for 20 min maintained vegetable quality by inhibiting unpleasant odors, the development of whiteness, and by reducing microbial populations. A single chlorine water wash was effective and resulted in better vegetable quality when compared with two washes. Samples washed for 20 min in ozonated water, however, had better vegetable quality and smaller microbial counts compared to samples washed once in chlorine water A 20 min ozonated water wash is an attractive method for the maintenance of vegetable quality and shelf-life in fresh-cut carrot shreds.
