Categorization means the process labeling or identifying an object based on what people already know or its similarity for people to be easily perceptible in external environment. If it is categorized, it is schematically conjectured from typical characteristic of the category. In this sense, the categorization of new products has an important effect upon the market performance. Nevertheless, the categorization of innovative new products is not easy and occasionally very ambiguous. In this study, we discuss how to strengthen the categorization strategy of new hybrid IT products through complementary bundling. The model of this study is based on Technology Acceptance Model (TAM) with resistance variable and verifies the statistical significance by undertaking a survey on consumers' awareness. In addition, we review the moderating effects of prior knowledge in the adoption process of complementary bundling. Through this analysis, we find out the structural relationship among the factors affecting adoption of complementary bundling. Also, it show that the influence of prior knowledge in respect of the adoption process is greater than others in case that there exists significant heterogeneity among strategic categories and complements. In conclusion, these findings suggest the following managerial implication. The categorization strategy of new hybrid IT product can be enhanced by complementary bundling, but the suitability among strategic category and complements should be evaluated exhaustively.

The effect of various nutrients for the production of the anti-complementary polysaccha- ride by Flammulina velutipes, was examined and the partial purification of the polysaccharide was carried out. The culture conditions and medium compositions considerably influenced the anti-complementary activity of the polysaccharides. When a culture was carried out at 23$\circ$C and pH 5.5 for 6 days in the synthetic medium supplemented with galactose and NaNO$_{3}$, the production of the anti-complementary polysaccharide was maximized. The crude polysaccharide, FV-1 was isolated from the culture broth and partially purified into two fractions, FV-1-II and FV-1-III by gel filtration using Sephadex G-100. FV-1-II was mainly consisted of xylose, mannose, galactose and glucose, and rhamnose, mannose and galactose, for FV-1-III. Also, the anti-complementary activity of FV-1-III was reduced partially in the absence of the Ca ion. When crossed immunoelect- rophoresis using anti-human C3 serum was carried out after incubation of normal human serum with the FV-1-III in the Ca ion free condition, a cleavage of C3 precipitin line was observed. These results indicate that the mode of complement activation by polysaccharide from Flammulina velutipes is via not only the classical pathway but also the alternative pathway.

The edible part of cucurbita moschata Duch, which is commonly used as a Korean traditional medicine as well as a popular food source, was studied to isolate anti-complementary substance. Extracts of Cucurbita moschata Duch showed significant anti-complementary activities on the classical pathway of the complement system. Especially, the ripe Cucurbita moschata Duch had more activity than that of the complement system. Especially, the ripe Cucurbita moschata Duch had more activity than that of the green one in terms of the overall anti-complementary activity. Among the extracts of various organic solvents of the ripe Cucurbita moschata Duch, chloroform and ethyl-acetate extracts, which are non-polar solvent extracts, showed the strongest activities. These results suggest that the major difference in the solvent extraction for the anti-complementary substances depends on the change in the chemical composition such as the fatty acid with the degree of ripening.

When new services are introduced, interaction among existing and new services has to be considered. The interaction can be characterized by the substitution or complementary effect among services. This paper analyzes how the interaction among services affects the customers' subscription decision in telecommunication services industry. Based on a face-to-face in-depth survey from a sample of 1,200 respondents, a new wireless internet access service or WiBro is analyzed to identify the substitution/complementary effect in relation to the existing other telecommunication services. Additionally, the important factors explaining both customers' subscription and substitution decisions are identified. The analysis results indicate that males and students are more likely to subscribe WIBro service. Interestingly, family size positively affects the subscription decision. However, heavy users of on-line game are reluctant to subscribe WiBro service. Among the potential WiBro subscribers, the customers who are less satisfied with the existing fixed line broadband internet access service are more likely to stop subscribing the fixed line service, which implies substitution by a new service. We believe that the consideration of the interactions among services is essential to devise a winning strategy for the new services in the highly uncertain telecommunications business environment.

Purpose: Many breastfeeding women have used complementary and alternative medicine, but the guideline for lactation does not exist on complementary medicine. This study is to investigate efficacy and safety of complementary and alternative medicine in breastfeeding. Methods: We searched for papers which had breastfeeding, complementary medicine, acupuncture and herb in the pubmed, scopus site and Korean journals. Results: 38 papers were found. Acupuncture could have the efficacy on hypogalatia and mastitis. Compound herb therapy had effect on hypogalactia, but none of herbs were investigated for safety all except for St John's wort. So more clinical trials about herbs would be needed. Massage and the other complementary therapies would be helpful for breastfeeding mother. Conclusion: Acupuncture could be a good treatment for hypogalactia and inflammation of the breast. For making guidelines on complementary and alternative medicine during lactation, more research will be needed.

This study aims to understand the advertising recall effect in accordance with color scheme of advertising by subdividing it into brand, picture, color, and style. The results of this study are like following. In the results of the study on advertising recall, first, there were significant differences in picture and color recall. The picture recall was the highest in complementary color scheme while color scheme was shown the highest in single and complementary color schemes. Regarding the advertising recall in accordance with subscription time of fashion magazines, second, the advertising recall can be different in accordance with subscription time of magazine, major, purchase experience, and interest. In case of picture advertising recall depending on major, third, majors highly recognized complementary color scheme in picture recall and also similar color scheme in color recall. Regarding the advertising recall depending on experience in purchasing magazines, purchasers highly recognized complementary color scheme in picture recall and also tone-in-tone color scheme in color recall. In case of the advertising recall in accordance with interest in fashion advertising, the group with interest highly recognized complementary color scheme in picture recall and also similar color scheme in color recall.

The main objective of this research was to understand the characteristics of complementary color scheme through the analysis of contemporary women's fashion color coordination as they appear in the 'Collections'. Data collection of 115 was done through review of 'pr$\hat{e}$t-$\grave{a}$-porter Collections' of four cities; Milan, London, New York, Paris. Statistical analysis of frequency and also qualitative interpretation of characteristics of complementary color harmony characteristics which appeared in four collections were completed. The main findings were as followed; (1) Only 115 complementary color schemes out of 4968 two color combinations appeared. Compared the comparative ratios of appearance frequency between the two color combination and the complementary color harmony, London showed the highest, and followed by New York, and Milan and Paris. (2)The combined color type of 'red+green' was the most frequently appeared, and followed by 'violet+yellow' and 'orange+blue'. For the type of tone harmony, the contrast tone showed the most, and followed by the similarity and identity. According to the type of complementary color combination, the type of tone harmony used differently. Some differences showed in the types of color harmony and tone harmony between collections. (3) The complementary color scheme which shown in four collections harmonized two opposite colors mainly through the strong tone contrast and this could cause tension along with interest in the image. The complementary colors intensified and brought out the attributes each other. More details, high contrast of two complementary colors of yellow and violet created a vibrant look especially when used at higher saturation. Sometimes, however, some tone variations of two hues neutralized the strong effect and sometimes enhanced each other. When they used in similarity tones or identity tones in light colors, the tension was reduced and became softened but still presented nice harmony. In the type of 'red+green' color harmony, the various color combinations were demonstrated, mostly through tone manipulation of green color. The similarity tone harmony, which used the most, could effect a better sense of harmony and present more sophisticated looks. When used in contrast tone harmony, some changes in its own color which have only one color of two the excessive intensity led a good harmony. The 'orange+blue' color harmony was shown the least and used three tone harmony almost the same ratio. In this color harmony, blue amplified its energy and brilliance of orange and seemed to work better when one color was at a lower intensity than the other. In harmony with a similarity and an identity tone, this color harmony produces a stable and calm image. (4) The complementary scheme appeared more frequently in the S/S collections than in A/W collections and showed some differences in the types of color harmony and tone harmony between seasons, however, no big differences between collections.

The complementary effect between FDI and its absorptive capacity has drawn more attention than before. This paper intended to explore the relationship between energy intensity and such complementary effect. The absorptive capacity of FDI shows various aspects among which we focus on the human capital, the financial system and the infrastructure in this paper. Using the panel data from 1990 to 2011, the study is processed between the 20 OECD and 20 Non-OECD countries. The empirical results shown that for OECD country, a complementary effect exists between FDI and its absorbability and it has the controlling effect on energy reduction. But the effect is only significant in the human capital and the financial system. The infrastructure variable is less important in OECD country due to their high development level. However, for non-OECD country, the complementary effect between infrastructure and FDI reduces energy consumption significantly, it can get to the point that the process for infrastructure to attract FDI and also benefits from it only blow its way to the Non-OECD, developing countries, without andy special effects for the OECD countries which has already highly build up their infrastructure. Also, the financial system in Non-OECD countries is at the primary stage yet, which is not easy to contribute efficiency. To make a conclusion, the complementary effect between infrastructure and FDI in OECD country and which between finical system and FDI in non-OECD country cannot enhance energy efficiency as expected.

With semiconductor scaling approaching the physical limits, devices including CMOS (complementary metal-oxide-semiconductor) components have managed to overcome yet are currently struggling with several technical issues like short-channel effects. Evolving from the process node of 22 nm with FinFET (fin field effect transistor), state-of-the-art semiconductor technology has reached the 3 nm node with the GAA-FET (gate-all-around FET), which appropriately addresses the main issues of power, performance, and cost. Technical problems remain regarding the foundry of GAA-FET, and next-generation devices called post-GAA transistors have not yet been devised, except for the CFET (complementary FET). We introduce a CFET that spatially stacks p- and n-channel FETs on the same footprint and describe its structure and fabrication. Technical details like stacking of nanosheets, special spacers, hetero-epitaxy, and selective recess are more thoroughly reviewed than in similar articles on CFET fabrication.

In our country, patients with diabetes mellitus are searching for complementary treatments to recover from illness, while they received treatments from the doctor. However, have been evaluated or investigated systematically. This study was carried out to explore application of complementary treatments for patients with DM. For this survey, questionnaires were developed by researchers and the data was collected from July to October of 1999. Among the 223 subjects, there is one general hospital, one oriental hospital, 15 area C.H.P, ahd 2 area health centers. The results were as follows: 1. The total number of cases was 223 and the average age was 62.85 years old and average duration of DM was 8.1 years. The number of patients who had experience with alternative therapies was 145 (65%). The number of those who have not undergone treatments was 78 (35%). 2. The 43.5% of experienced CAM were advised family and relatives. Only 30.3% approved the effect of CAM and 52.5% said that If another a new CAM is introduced, they will try it. 4. Ninety three kinds of complementary treatments were used. Among the used items, 63.7% was various types of plants, 21.6% was animal material and 14.7% was the mixed group. As a single item, Bombyx Mori (Silkworm) was the most frequently used (10.5%) followed by the bean, mushroom, Morus bombycis (mulberry), Ginseng, Commelina Communis (Dalgaebi), Chinese medicine, root of Rosa rugosa (Haedangwha). 5. Among the used items, Trichosanthes kirilowii Max. Eucommia ulmoides Oliver, Commelina Communis, Aralia elata, pine needle, mulberry fruit, root of Rosa rugosa. Ginseng, Lycii Fructus, Dioscorea radix, Polygonatum odoratum, Cassia tora L, Bombyx Mori, loach, Crucian carp were based upon the pharmacological function of effect for control of diabetes mellitus symptom. 6. In the analysis of the relationships between the general characters of the patients with new complementary alternative medicine try and hospital treatment; 1) The shorter group suffered from DM (p=.038), poor Self-MBG (p=.037) and wanted to try new complementary alternative medicine. 2) The group of DM education experience were carried out hospital treatment well (p=.045). In conclusion, further study will be required for the patients experience using alternative therapies as the D-M in terms of holistic view of patients.
