Purpose - This study proposes a strategic model for the late mover to effectively penetrate an industry that is dominated by a leading company. Thus, this study presents strategic implications for several late movers in overcoming the advantages of the leading company. Research design, data, and methodology - This study begins with a literature review followed by the formation of a strategic model that consists of: Repositioning, Utilization of Competence, Strategic Leadership, and Innovation. Specifically, this research analyzes LG Electronics (LG) as an example and investigates how LG infiltrates and grows in the water purifier market, overcoming the advantages of the powerful leading company. Results - The major steps taken by LG are summarized into four. First, LG studied the market, which had been conventionally treated as a single market. To penetrate the market, LG founded a new, special market segment. Subsequently, LG further segmented the market, executing a marketing strategy for each segment. Second, the unbending will of top managers was a key factor that addressed the challenge persistently. Third, even though LG was the late mover in the water purifier market, it had several technology competences such as compressor, refrigeration cycles, and algorithms. LG had profound knowledge in technology and used it effectively. Fourth, LG created a premium market through three innovative and distinguished factors such as the stainless water tank, sterilization service, and luxury design. Conclusions - This research draws four key findings from the example of the late mover in the water purifier industry: the reestablishment of a strategic position based on environmental change is an effective strategy for the late mover; strategic leadership is an important motive to generate late mover performance; and the late mover can utilize its existing knowledge and resources to overcome the first mover, such as presenting new added value compared to existing products as an effective catch-up strategy. Consequentially, through the study of performance determinants and the market penetration strategy of the late mover, this research has significance in providing basic material for companies trying to penetrate the market.

The growth of lactic acid bacteria (LAB) generates a high number of metabolites related to aromas and flavors in fermented dairy foods. These microbial proteases are involved in protein hydrolysis that produces necessary peptides for their growth and releases different molecules of interest, like bioactive peptides, during their activity. Each genus in particular has its own proteolytic system to hydrolyze the necessary proteins to meet its requirements. This review aims to highlight the differences between the proteolytic systems of Streptococcus thermophilus and other lactic acid bacteria (Lactococcus and Lactobacillus) since they are microorganisms that are frequently used in combination with other LAB in the elaboration of fermented dairy products. Based on genetic studies and in vitro and in vivo tests, the proteolytic system of Streptococcus thermophilus has been divided into three parts: 1) a serine proteinase linked to the cellular wall that is activated in the absence of glutamine and methionine; 2) the transport of peptides and oligopeptides, which are integrated in both the Dpp system and the Ami system, respectively; according to this, it is worth mentioning that the Ami system is able to transport peptides with up to 23 amino acids while the Opp system of Lactococcus or Lactobacillus transports chains with less than 13 amino acids; and finally, 3) peptide hydrolysis by intracellular peptidases, including a group of three exclusive of S. thermophilus capable of releasing either aromatic amino acids or peptides with aromatic amino acids.

Marek's disease (MD) is caused by a ubiquitous, lymphotropic alphaherpesvirus, MD virus (MDV). MD has been a major concern in the poultry industry due to the emergence of increasingly virulent strains over the last few decades that were isolated in the face of comprehensive vaccination. MD is characterized by a variety of clinical signs, amongst them neurological symptoms, chronic wasting, and most notably the development of multiple lymphomas that manifest as solid tumors in the viscera and musculature. Much work has been devoted to study MD-induced oncogenesis and genes involved in this process. Among the many genes encoded by MDV, a number have recently been shown to affect the development of tumors in chickens, one protein directly causing transformation of cells (Meq) and another being involved in maintaining transformed cells (vTR). Other MDV gene products modulate and are involved in early lytic in vivo replication, thereby increasing the chance of transformation occurring. In this review, specific genes encoded by MDV that are involved in the initiation and/or maintenance of transformation were briefly summarized, and limits of current vaccination and new control strategies against MD, particularly how modem molecular biological methods may be used to improve strategies to combat the disease in the future, were discussed.

The point of impact, the shot group, and the flight traces depend on the combination of unique features which decide moving traces of the arrow (paradox of the archer, length of the arrow shaft, weight, angle of the feather, and spline of the arrow shaft). The more dense the impact points in the shot group and the earlier elimination of paradox of the archer, the higher assessment is given for the product. However, there is no way to objectively assess the efficiency and quality of the arrow, and there is no numeric data to be used as the basis for comparison with other products. Although capturing the images of flying arrow using a high-speed motion picture camera is possible, we are limited to observation from specific view angle only. Hence, the criteria for efficiency and quality assessment are mostly based on subjective opinions of experts or hunters, or review on consumers' remarks. In this paper, we propose a hardware composition that are based on three detection frames consisting of line lasers and photo diode arrays without the high-speed motion picture camera. Predicated on measured coordinates data, a nobel method for the archer's paradox measurement, a key parameter that determine the arrow's trajectory, and corresponding numerical analysis model is proposed.

Among polyunsaturated fatty acids (PURAs) targeted for manipulation in animal tissues (poultry eggs and meat), omega-3 PUFAs(n-3 PUFAs) are discussed in this review. 3 or 5% dietary menhaden oil (MO) supplemented layer diets was reported to increase docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) contents in the egg. MO at 1.5% also increased the deposition of up to 180mg total omega-3 fatty acids / yolk. Utilization of 5% ground flax seed (FS) resulted in similar total omega-3 fatty acid (FA) deposition as 1.5% MO. However, the basic feed formulations used in the Canadian feed industry usually include 10 to 20% FS in the egg laying diets. Recently several studies reported that addition of tocopherols in layer diets increased the tocopherol content more in the egg than any other tissue. One of reports said that 3.5% dietary oil with added tocopherols resulted in increasing tocopherol deposition and FA composition of the egg and other tissues. In the poultry meat, redfish meal (RM;4, 8, 12, 15 and 30% of diet) or redfish oil (RO;2.1 or 4.2% of diet) added to the practical corn-wheat-soybean based diets resulted in an increase in omega-3 FA and docosapentaenoic acid (DPA) contents in broiler meat lipids. Linseed oil (LO;1.0, 2.5, and 5.0% of broiler diet) supplemented in broiler diets also resulted in omega-3 FA and the ratio of omega-6 being significantly higher in poultry meat lipid than MO. Concern about fish flavor resulted in research about fish oil (FO) supplementation in broiler diets. Without the use of antioxidants, no more than 1.5% FO should be fed to broilers due to unacceptable orders from the chicken carcasses. One recent research project found that over 50mg/kg of vitamin E was required for maintaining the stability of unsaturated lipids in the meat. In regards to 'fishy'or 'crabby'taint in the eggs and poultry meat, poultry products remained acceptable when dietary fish oils were stabilized with antioxidants.

환경친화적인 소비행태란 어떤 제품의 환경친화도가 높아지면 그 제품에 대한 지불용의도 커지는 것을 의미한다. 이러한 소비행태를 지닌 소비자들로 구성된 시장을 green market이라고 부른다. green market에 대한 거의 대부분의 기존 연구는 단위배출기준(unit emission standard), 환경세 등 환경정책수단의 효과를 분석하였다. 향후 소비자들의 환경친화적인 성향은 지속적으로 강화될 것이다. 이에 본 연구는 수직차별화 모형을 바탕으로 소비자 환경친화도의 변화가 오염물질 배출량에 미치는 영향을 고찰하였다. 본 연구에서 도출된 주요 결과는 다음과 같다. 먼저 제품의 필수재적인 성격이 강하여 모든 소비자들이 제품을 구매하는 경우에는 소비자들의 환경친화적인 성향이 높아지면 오염물질 배출량은 감소한다. 이는 소비자들의 환경친화도가 변화하여도 총생산량에는 아무런 변화가 없기 때문이다. 반면 일부 소비자들이 제품을 구입하지 않는 시장의 경우에는 환경친화적인 성향이 낮은 소비자들의 환경친화도가 상대적으로 크게 상승하면 오염물질 배출량이 증가할 수도 있다 이는 무엇보다도 환경친화적인 성향이 낮은 소비자들의 환경친화도가 상대적으로 크게 상승함에 따라 제품의 총생산량이 증가하기 때문이다.

This study examined the relative importance and the effective utility of fermented milk by consumers. The questionnaire was developed by an in-depth interview and literature review and was surveyed on-line. Statistical analysis was carried out descriptive analysis, ANOVA, paired t-test, and conjoint analysis using the SPSS package. First, an analysis of the consumption status of fermented milk found that the consumption frequency was 1-2 times/week (36.2%), 3-4 times/week (26.5%). The product choice attributes of fermented milk were found to be the same with 'taste' (3.93) and 'manufacturing date/expired date' (3.92), rated the highest, followed in order by, 'sanitary quality' (3.82), 'origin of ingredient' (3.81). Comparative analysis of the importance and satisfaction level of the choice attributes of fermented milk showed that the choice attributes with lower satisfaction compared to importance were 'taste', 'nutrients', 'manufacturing data/expired date', 'sanitation quality', 'price', 'manufacturing method' and 'certification of quality' (p<0.001, p<0.01). 'Price' and 'certification of quality' were the choice attributes of fermented milk classified as 'Focus Here' because of its high importance and low satisfaction. The preferred combination of relative importance in choice attributes of the fermented milk was 'domestic resource', 'Eat with spoon', and 'none additives'. Therefore, it is believed that sales will increase if dairy companies can improve the 'price' and 'certification of quality'. In addition, the use of domestic ingredients in the development of new fermented milk products in the future could be an important marketing factor in consumer choice.
