  • The purpose of this study was to determine if vitamin B-2 and vitamin B-6 deficiency affects hematologic profile in vivo. Rats were fed a vitamin B-2 deficient (-B2) diet or a vitamin B-6 deficient (- B6) diet or a combined vitamin B-2 and vitamin B-6 deficient (-B2-B6) diet or a control diet for 6 weeks. Hematocrit (Ht), hemoglobin (Hb), plasma iron (PI), transferrin saturation (TS) and liver iron concentration (LI) were compared. In -B2 rats vs. control rats, PI, TS and LI were significantly lower but Ht and Hb were not. In - B6 rats vs. control, Ht and Hb were significanty lower but LI was higher. The -B2-B6 rats had intermediate effects in Hb, PI, TS and LI and a decrease in Ht. The repletion with a contro diet for 2 weeks resulted in significant improvements in hematologic indices and LI in both - B2 rats and - B6 rats. This study suggests that the intakes of vitamin B-2 and vitamin B-6 are important for preventive and therap\ulcornereutic approaches to improve the hematologic status in nutritionally anemic groups.

  • Many buying and selling companies have participated in B2B electronic commerce in order to boost sales and cut down purchase prices respectively. There are some studies on buying and selling companies performances of using B2B e-marketplaces which provide electronic B2B transaction services such as finding transaction partners, providing on-line transaction process like auctioneering, etc. This study investigates the critical failure factors against B2B e-marketplace in other words B2B market-maker or B2B intermediary. We proposed 4 hypotheses asserting that 4 critical failure factors make reverse effects on B2B intermediary performances. We adopt the Balanced Score Card (BSC) framework to evaluate B2B intermediary performance. Data were collected from 46 respondents of B2B intermediaries in Korea. Analyses showed that traditional off-line B2B practices like refunding to buyer or transactions without legal documents and low quality of product information and catalog are critical failure factors against B2B intermediary performance.

  • Marketing activities play an important role in determining sales performances for B2B companies; however, prior research implies that the effect of marketing activities in the industrial market cannot be inferred from findings in the consumer market due to their differences such as types of customers or products. We further note that B2C companies (i.e. B2B client companies) serve individual consumers, and thus, B2B sales performance can be better understood as consumer market contexts are also taken into account. In this research, we study B2B marketing activities and B2C market contexts, and their effects on B2B sales performance. To this end, we focus on three factors : sales calls conducted by B2B companies, and market commercialization and social interactions in regions where B2C companies operate. Our empirical analyses provide the following results. First, B2B sales performance improves in proportion to sales calls. When sales calls serve as the means to provide product information, they help client companies understand product benefits and make purchases accordingly. Second, B2B sales performance increases as B2C markets become more commercialized, but the effect of sales calls on B2B sales declines. Commercialized markets are more attractive to individual consumers and thus, lead to greater sales in the consumer market. However, the role of sales calls as information sources weakens as B2C companies share product information themselves and develop expertise in commercialized markets. Finally, B2B sales are greater in urban markets compared to suburbs. However, the effect of sales calls on B2B sales increases in suburban markets compared to the urban counterpart. Cohesive social interactions in suburbs hinder information diffusion among B2C companies, which in turn strengthens the role of sales calls as information sources. We theoretically contribute to the B2B marketing literature and managerially suggest strategies to improve B2B sales performance.

  • 본 연구에서는 비타민 $B_{2}$ 결핍이 3일간 금식과 6일간 감식시 체내 저장연료 이용에 어떠한 영향을 미치는 가를 알아본 결과, -B2군은 pair-feeding을 감식시켰음에도 불구하고 +B2군에 비해 체중이 유의적으로 낮게 나타났으며 식이 이용효율도 낮았다. 모든 장기, 특히 간장 무게는 -B2군이 +B2군에 비해 무겁게 나타났으며, 감식과 금식시에도 -B2군의 장기무게가 가벼워졌으나 여전히 유의하게 무거웠으며 -B2군의 간장 중성 지방이 높게 나타나 지방간 증상으로 간장이 비대해진 것으로 추정된다. 혈장 포도당과 단백질 함량은 섭식, 금식 및 감식시 +B2군과 -B2군 사이에 유의적인 차이가 없었다. 혈장 중성지방 수준은 +B2군에 비해 -B2군이 섭식시는 높은 수준을 나타냈으나 금식 및 감식시에는 유의적인 차이를 나타내지 않았다. 간장 중성 지방도 이와 유사한 경향을 나타내었다. 혈장 유리지방산 수준은 섭식시에는 +B2군과 -B2군 사이에 유의적인 차이가 없었으나, 금식으로 인해 +B2군은 유리지방산 수준이 증가하였고 -B2군은 오히려 감소하여 -B2군이 +B2군 보다 낮게 나타났다. 그러므로 비타민 $B_{2}$ 결핍으로 인해 이 유리지방산의 유리가 원활히 일어나지 않았거나, 비타민 $B_{2}$ 결핍으로 인해 지방산화가 저해된 것이 금식으로 지방이 에저지원으로 이용되어야만 하는 상황이 발생하여 감소된 지방산 산화가 다소 회복된 것으로 추정된다. 금식 및 감식시 +B2군에 비해 -B2군이 근육단백질 수준은 높은 경향을 나타내었고 근육 글리코겐 수준은 낮은 경향을 나타내어 -B2군이 심각한 비타민 $B_{2}$ 결핍으로 저지방이나 근육단백질을 이용하지 못하게 됨에 따라 근육 글리코겐을 이용한 것으로 추정된다. 이는 +B2군에 비해 -B2군의 뇨중 총질소 배설량이 적은 것으로도 재확인되었다. 그러므로 금식이나 감식시 체지방이나 체단백질을 이용하는 에너지 보충 적응기전이 일어나야 하나 비타민 $B_{2}$ 결핍상태에서는 이러한 체내 열량공급이 지장을 받게 되며, 체단백질 이용저하로 포도당 신생이 영향을 받아 장기간의 금식 또는 감식시에는 혈장 포도당 수준도 낮아질 것으로 예상된다.

  • As $40%{\sim}60%$ of the construction project expense is used for the purchase and procurement of construction materials, construction companies are attracted by the promise of online procurement of construction materials through the B2B e-Marketplace. B2B e-Marketplace can save construction companies time and money spent through the off-line procurement. Construction B2B e-Marketplaces can energize the construction market dominated by major construction companies. It will expand the business scope of small and medium construction material suppliers and construction companies. Current B2B e-Marketplaces underperform in all industries due to low participation. Excluding some construction B2B e-Marketplaces led by major construction companies, most construction B2B e-Marketplaces show poor performance in terms of revenue and transaction. Researches are needed in the area of discovering the problems of current construction B2B e-Marketplace and identifying the factors for participating in the construction B2B e-Marketplace. This research conducts a case study to analyze the current status of construction B2B e-Marketplace.

  • With development of IT technology, B2C Social Commerce makes the change from closed type of transaction to the form of an open trading. Also by dramatically reducing the intermediate distribution and removing distribution costs, it provides goods at unbeatable prices to consumers. Depending on the flow of the times, the business-to-business struggles with the difficulty of PRM management and fast promotion of new products. Therefore, it is required B2B Social Commerce, new platform that can collect distribution and consumption firms in one place which is similar to B2C Social Commerce. Unlike the case of B2C social commerce, B2B Social Commerce should have an essential element, Installment payment system to pay over the period without purchase in accordance with the payment paid as a lump sum. B2B Social Commerce model which is introduced in this study will provide the solution of B2B transaction problems, opening up new markets and bring the expansion of the electronic market.

  • Faced with the recent global economic recession, academics looked to the industrial B2B and B2C markets as potential new growth engines. In the B2B market, focusing on the relationship with customers, the relationship benefits are important, and institutional factors will affect the relationship and relationship values with customers. In this study, the relationship values between South Korea and Taiwan are compared by considering their national characteristics. By applying a mixed research method based on sequential exploratory design, 6 relationship values (supplier knowhow, service support, time to market, delivery performance, personal interaction, and product quality) are extracted. In particular, South Korea and Taiwan give priority to supplier knowhow and service support, respectively. Our research findings have both theoretical and practical implications for other emerging countries, as well as developed countries.

  • In this study, the effect of the size of B powder on the critical current density (Jc) of MgB2 prepared by an in situ reaction process was investigated. Various combinations of B powders were made using a micron B, ball-milled B and nano B powders. Micron B powder was reduced by ball milling and the milled B powder was mixed with the micron B or nano B powder. The mixing ratios of the milled B and micron or nano B were 100:0, 50:50 and 0:100. Non-milled micron B powder was also mixed with nano powder in the same ratios. Pellets of (2B+Mg) prepared with various B mixing ratios were heat-treated to form MgB2. Tc of MgB2 decreased slightly when the milled B was used, whereas the Jc of MgB2 increased with increasing amount of the milled B or the nano powder. The used of the milled B and nano B power promoted the formation MgB2 during heat treatment. In addition to the enhanced formation of MgB2, the use of the powders reduced the grain size of MgB2. The use of the milled and nano B powder increased the Jc of MgB2. The highest Jc was achieved when 100% nano B powder was used. The Jc enhancement is attributed to the high volume fraction of the superconducting phase (MgB2) and the large grain boundaries, which induces the flux pinning at the magnetic fields.
