Purpose: The liposuction has been generalized & undergone in the field of plastic surgery and it has had a great influence on fat graft. But despite of liposuction and fat injection being performed widely, we did not focus on complication associated with donor site. So we reported satisfactory result with the intraoperative sustained limited expansion & direct closure to donor site tissue necrosis after liposuction and analyzed the cause & measures of donor site necrosis with the literature investigation Methods: From November 2007 to June 2008, we treated four cases of tissue necrosis and infection surrounding the thigh and forearm. Necrosis after liposuction was 1 case, donor site necrosis after fat injection were 3 cases and MRSA was detected in 2 cases. first, we debrided the necrotic tissue and treated with potadine gauze soaking dressing & susceptible antibiotics. After confirmation of healthy granulation tissue, we used intraoperative sustained limited expansion and closed directly of defect & observed the results. Results: The patient was displeased and worried with the unexpected damage concerning the donor site and the procedure concerning time and financial exhaustion, but after confirming no contracture of the scar tissues and only a thin or slightly widened line of scar, showed satisfaction. Conclusion: Because it is fastidious to avoid donor site complication after liposuction & fat injection, enough explanation and understanding on possible complication to donor site are necessary and careful surgery procedure & materials are required. But if donor site necrosis were occurred although close consideration of possible causes of necrosis, we should think about not only wound healing process but also the sequela like scar contracture & cosmetic effect and treat the most adequate method to satisfying both concerns.

As an essential means to the exploitation of new demands, the export of agri-food has the price-supporting effect on the domestic agri-food and its expansion can be a good way to increase farms' income. Of course, to enhance farms' income under the liberalization of the market, it is necessary to have countermeasures considering various factors. To this end, the study understood the experiences of farms doing exports and looked into ways to improve them by reviewing their motivations to export, difficulties, requirements, etc. In this context, the study conducted the purposive sampling among tomato export farmhouses in Jeongseon-gun in the export enforcement phase and executed the theme analysis. The research findings and suggestions are as follows. First, in order to enhance the level of commercialization of Jeongseon-gun tomatoes and reinforce the trade bargaining power, it is necessary to form the consensus on policy and make the scaling of the site based on the strong organization power. To this end, it requires the active role of agricultural cooperatives that take a big portion of distribution in the site and distribute its profits directly to farmhouses. Second, it is necessary to set clear target markets for Jeongseon-gun tomato export farms and set sales strategies for each target market. That is, in order to expand the export of Jeongseon-gun tomatoes, after clarifying local sales and export sales, export farmhouses should focus on quality management and secure the quantity for export. Third, to expand the export to Japan which already has the foundation for the export of Korean tomatoes, and to new export countries of China, Russia, etc., it is necessary to set the 'Two-Track Strategies for Export Market (particular item for focus and particular area for focus)' through the building of network of tomato export areas in Gangwon-do. In conclusion, to expand the export of Jeongseon-gun tomatoes, agricultural cooperatives and leaders together should build the strong organizational power with farmhouses and secure the quantities for export. And, according to the 'Two-Track Strategies for Export Market (particular item for focus and particular area for focus)', export infrastructure and export operational system should be built and to do so, the solidarity of tomato export farmhouses in Gangwon area should precede.

Posbist reliability of typical systems is preliminarily discussed in Cai (1991). In this paper, we focus on the posbist reliability analysis of some typical systems in depth. First, the lifetime of the system is dealt as a fuzzy variable defined on the possibility space (U, ${\phi}$, $P_{oss}$) and the universe of discourse is expanded from (0, $+{\infty}$) to ($-{\infty},\;+{\infty}$). Then, a concrete possibility distribution function of the fuzzy variable is given, i.e., a Gaussian fuzzy variable. Finally, posbist reliability of typical systems (series, parallel, series-parallel, parallel-series, cold redundant system) is deduced. The expansion makes the proofs of some theorems straightforward and allows us to easily obtain the posbist reliability of typical systems. To illustrate the method a numerical example is given.

This paper proposes an algorithm for rejecting mismatched points (known as outliers). The proposed algorithm identifies and rejects outliers in image pairs obtained under automobile-like motions which consist of two translations and one rotation. The camera rotation is approximated to the image shift by assuming that the narrow field of lens is used. The voting method estimates the focus of expansion (FOE) while shifting one of the images. Using the properties of the FOE, the outliers are rejected while most of the inliers are retained.

Home meal replacements (HMR) are kinds of convenient foods as cooked or semi-cooked foods, which are produced outside of home, to eat directly or after simple cooking in substitution for traditional home meals. Recently the market size for HMR is expanding rapidly around the world due to the changes of global consumer trends, growth of single-person household, increase in economic participation of women, aging population, and so on. The Europe takes over 52.4% of the global market share for HMR in global HMR market, and North America, Asia-Pacific, and Africa-Middle East are following. The most popular HMR products in US and Europe are frozen foods, whereas the market share of chilled products in Asia including Japan, South Korea, and Vietnam are much higher than that in US and Europe. Currently, the trends in HMR is focus on the expansion of the list of products that replace for meals with simple cooking, but it is expected that nutrition-enforced HMR product for aged persons or patients who live alone are requested for the further growth of the HMR market.
