  • Test colors are halftone dot printed at the rate of 10% halftone dot area by process inksblack, cyan, magenta and yellow ink. Reproduced colors are measured by the weighted-ordinate colorimetric method and the direct colorimetric method. The weighted-ordinate colorimetric method compare favorably with the direct colorimetric method, because the former has good regular changes of tristimuIus values, chromacity coordinates, excitation purities, value functions and has smaller errors of dominant and complementary wavelengths than the latter. All test colors classify with the Munsell renotation.tation.

  • The energy efficiency of wireless infrastructure and terminals has been drawing renewed attention of late, due to their significant environmental cost. Emerging green communication paradigms such as cognitive radios, are also imposing the additional requirement of flexibility. This dual requirement of energy efficiency and flexibility poses new design challenges for implementing radio functional blocks. This paper focuses on the area vs. power trade-offs for the type of channel filters that are required in the digital frontend of a flexible, energy-efficient radio. In traditional CMOS circuits, increased area was traded for reduced dynamic power consumption. With leakage power emerging as the dominant mode of power consumption in nanoscale CMOS, these trade-offs must be revisited due to the strong correlation between area and leakage power. The current work discusses how the increased timing slacks obtained by increasing the parallelism can be exploited for overall power reduction even in nanoscale circuits. In this context the paper introduces the notion of 'area efficiency' and a metric for evaluating it. The proposed metric has also been used to compare the area efficiencies of different classes of time-shared filters.

  • Objectives : To investigate the prevalence and utilization pattern of complementary and alternative medicine (CAM) in individuals with type 2 diabetes. Methods : We conducted a nationwide survey and a total of 535 individuals with type 2 diabetes were asked about their demographic, diabetes-related characteristics and CAM use. We used multiple logistic regression modeling to determine independent predictors of CAM use. Results : Of the 535 subjects, 417 (77.9%) used CAM in last 12 months. The most commonly used modality was red ginseng (17.9%). CAM use was independently associated with being married, northern area residence, higher education and diabetes duration of 3-5 years. More than half(58.3%) of the CAM users used it expecting a better outcome in addition to conventional therapy. Information sources about CAM were mostly friends (36.0%) and family (31.9%), only 28.1% of diabetic patients seek counsel from medical doctors or oriental medical doctors about CAM. Many people perceived CAM as effective (62.7%) and reported side effects only rarely (1.2%). Conclusions : Many diabetic patients used CAM and found it effective, which urges clinicians to pay attention to CAM use of their diabetic patients. Also, further studies are required regarding efficacy and safety about CAM.

  • With the appearance of many new types of fashion stores in Korea, competitions among fashion store types art fiercer than ever before. As consumers alternatives in fashion store selection increase, they select different store types to purchase different product types. Therefore, the probability of patronage mix behavior according to product type increases. Understanding consumers patronage mix behavior, finding out the determinant attributes of fashion stores for each product type, and analyzing competitive structures among fashion stores are important to retailers and marketers for building a successful merchandising and marketing strategies. An empirical study was conducted to analyze the competitive structure among the store types by consumers' patronage mix behavior. A questionnaire was developed and data were collected from 464 adult women living in Seoul area in Korea. Factor analysis, paired t-test, ANOVL Duncan test, and discriminant analysis were employed to analyze the data. Data regarding patronage mix behavior by product type proved that certain store types had ‘natural dominance’ in a particular product type as Hirschman(l978) pointed out. Also, a new analytic method of the competitive structures among fashion store types was suggested in the study, by which a specific store type retailer can analyze his/her own customers' patronage mix behavior by product type. The analysis will enable retailers to distinguish which of their competitors are substitutive, selling same product types, and which are complementary, selling different product types. Retailers have to concentrate on the strategies for the substitutive competitors rather than complementary competitors because their marketing abilities and resources are limited.

  • The purpose of this study was to investigate the perception and utilization of Complementary and Alternative Medicine (CAM) for diabetic patients in Busan. The subjects were 227 patients at two general hospitals (over 400 bed). This study was performed through the interviewing process using questionnaires conducted from January to April, 2010. Of a total of subjects, 109 patients (48.0%) had taken CAM at least one time. The patients used CAM recognized that they were 'auxiliary medicines' (39.4%), 'supplementary health foods' (32.1%) and 'medicines' (19.3%), but inexperienced patients perceived them as 'supplementary health foods' (29.6%), 'unscientific treatment' (22.6%) and 'medicines' (20.2%), It was significantly different between two groups of patients (p < 0.001). The number of CAM types used for the patients was 51. The CAM types were plant foods (64.3%), dietary supplement (23.6%) and animal diets (12.1%). The patients used an average of 5.9 different kinds of CAM and an average of 3.8 years them and paid \93,345 per month. The patients with diabetic complications and for longer morbidity periods used CAM for significantly (p < 0.05) longer periods. The mean effectiveness scores of the patients used CAM were 3.31/5.00 for efficacy satisfaction, 3.58/5.00 for fewer side effects compared to those of oral drugs, 3.60/5.00 for psychological stability, 3.81/5.00 for easiness to use, and 3.06/5.00 for economic satisfaction. Of the patients that used CAM, 55.9% did not consult with doctors about CAM. More than two-thirds of the patients (77.1%) did not feel the need to consult with doctors.

  • The paper is basically designed to reveal substitutability or complementary nature of export and import among Korea, China, and Japan by employing unit root test, cointegration technique, and vector error correction model(VECM). Empirical evidences are shown that the trading among these countries has been dominated by a complementary nature in the short run which enables it to promote trading in those countries. In the long run, however, the substitutability nature effects strongly to the trading among Korea, China, and Japan. To this end, it could be tentatively concluded that market-oriented trading policies are more effective to stimulate the export and import in those countries in the short run, while a trading policy has to be selectively implemented by the substitutability nature in the long run basis. For instance, a stability policy for exchange rates and various commercial policies could be set for a short term target. Whereas, the substitutability nature should be counted in building up a new industrial structure or in implementing FTA agreement among Korea, China, and Japan.

  • A joint venture approach to the marketing, organization, and execution of a project should be considered when the combined strengths of two or more entities result in a joint organization with unique credentials in a targeted business area. A joint venture is based on a complementary relationship: one party may lack one or more major elements needed for market penetration, such as technology, design-construct capabilities, geographic location, or financial strength; the other party should be able to compensate for these areas of weakness. The purpose of this study is that suggests the development direction of a joint venture, the proper organizational approach

  • Spinach is a vegetable crop which is widely grown over a large area especially in Punjab province of Pakistan. Leaf curling and enations on spinach plant collected shown to be associated with the begomovirus Pedilanthus leaf curl virus (PeLCV) and Shahdadpur strain of Cotton leaf curl Multan betasatellite ($CLCuMB^{Sha}$). Defective molecules of half and quarter size derived from monopartite begomoviruses are usually generated by the deletion of virion-sense sequences. Characterization of defective molecules of PeLCV from spinach revealed that the molecules of half the size are derived from the deletion of complementary-sense genes while quarter size molecule appears to have evolved by further deletion. This is the first report of the begomovirus-betasatellite complex on spinach and unusual defective molecules derived from deletion of complementary-sense genes in Pakistan.
