This paper empirically studies the relationship between R&D expenditures and firms value. First, we can conjecture that R&D expenditures are enhancing the firms value. Such findings depend on an existing research, which R&D expenditures are intangible asset rather than expenses. Although, under U.S. accounting standards, financial statements do not report intangible assets but costs. Second, we can conjecture that short-term, the rate of increase in R&D expenditures had negative influence on firms valuation, because such findings indicates that R&D spending of costs incur mis-pricing. But long-term, consistently R&D expenditures may attract investors on the stock market. Third, lately firms focus on capital efficiency management, such a firms R&D expenditures incur high ROE. Generally investors put too much confidence in capital efficiency management and high ROE may attract investors on the stock market. Finally, High-Tech through the R&D investment improve firms competitive advantage, by competitive advantage, firms have reduced cost and raised productivity in the end improve firms value.

To date, the literature has focused on formal R&D activities, such as internal, joint or external R&D, but informal R&D activities, such as job training or design, can also have a positive impact on technological innovation. To address this research gap, this paper examined 1) the influence of informal R&D activities on innovation adoption, and 2) the differences between formal R&D-oriented and informal R&D-oriented firms in process and product innovation. For this, statistical analysis was conducted using the data set from 2012 Korea Innovation Survey. The results suggest that 1) informal R&D activities can influence process innovation, and 2) firms engaging in both informal and formal R&D actively adopt product innovation. Findings suggest that 1) firms should recognize the importance of informal R&D and 2) national R&D policy should reflect the positive role of informal R&D in technological innovation.

In this study, we constructed a database of dyeing concentrations of all reactive dyes used for dyeing linen according to the thickness of the linen fabric and attempted to improve the reproducibility of the dyeing process for the commercialization of linen fabric materials. Linen fabric is a natural cellulose material that is comfortable and suitable for eco-friendly trends. It is a typical summer material with excellent breathability and thermal conductivity, quick moisture absorption and dissipation, and a cool touch. Dyeability and fastness were evaluated depending on the thickness of the linen fabric using a monochlorotriazine (MCT) reactive dye and bifunctional yellow, red, and blue dyes. All three colors of the MCT reactive dye and bifunctional dyes exhibited a darker shade as the fiber thickness of the marker increased. Fastness to washing was excellent at grades 4-5 or higher, regardless of the color of the dye and the number of linen fabrics. Although some color-fastness differences were noted, with the color change occurring most frequently with blue color, the fastness variations with dye type were mostly similar. The results of this study are expected to facilitate the selection of reactive dyes according to the thickness of the linen fabric based on the basic data from the laboratory, which will aid in the mass production of linen fabric and benefit the fashion industry.

This study focused on the epoxy resin production process, which uses the steam of 155 ℃ or higher as a heat source, and discards all condensate generated. A part of the process is operated at low temperatures of 70 ℃ or below, thus there are opportunities to reduce the steam consumption by recycling wasted condensate as a heat source for the low temperature section of process. In this study, we developed process models that can reduce steam by recovering waste heat through recycling condensate and conducted a case study to find an optimal condensate recycling system. Three different process designs were proposed and economic evaluations were performed by comparing annual capital costs and steam savings in each case. Finally, an annual steam consumption of the low-temperature section could be reduced by up to 67.6%, which could also bring an additional economic benefit of 522.1 million won/yr.

Animal welfare advocates, claim that the induced molting by fasting be avoided. This study was conducted to evaluate the effect of molting induced by various feeding methods on productivity and egg quality in laying hens. We used 400 flocks of 60-week-old leghorn laying hens in four treatments(five replicates of 20 hens each): fasting method (C), feeding single corn grain diet (T1), feeding single wheat bran diet (T2) and feeding single alfalfa meal diet (T3). As the result of the experiment, egg production and daily egg mass significantly decreased only in T1 compared with the control during the $1{\sim}4th$ week after the secondary egg laying (P<0.05). Although the amount of feed intake was significantly less in T1 group during the $1{\sim}4th$ week compared to the control, no significant difference was detected during the total period (P>0.05). In addition, no significant difference of feed conversion was observed between treatment groups. In terms of egg quality, the egg shell thickness was significantly improved in T1 group than the control group by feeding only corn at the 10th and 14th week after the secondary egg laying (P<0.05), but the significant decrease was observed at the corn (T1) and wheat bran (T2) fed treatment groups than the control group at the 26th week of the experiment (P<0.05). The eggshell strength and haugh unit did not show any difference by the molting methods. Egg yolk color was significantly decreased in T1 and T2 group than the control group at the 6th week (P<0.05). However, T1 and T2 group resulted to show significantly high egg yolk color at the 18th week of the experiment (P<0.05). As the result of the experiment, no large difference was observed in the productivity by the feeding molting method and by the fasting induced molting method. In addition, the single diet fed feeding induced molting method by using alfalfa revealed to show more satisfactory trend than the corn or wheat bran single diet fed feeding induced molting methods even if no statistically significant difference was found in terms of egg productivity.

This study investigates the relationships among SMEs' innovation capacity, standardization education activities, and performances. Employing about 900 SMEs in the ICT and electronics electricity industries, this study used regression analysis and examined the effects of standardization education activities on performance and the moderating effect of innovation capacity. The results indicate that standardization education activities positively affect SMEs' production and quality improvement and R&D activity improvement. The results also show that R&D investment ratio moderates the relationship between standardization education and production and quality improvement. This study provides practical insight into why firm managers should pay attention to standardization education and innvation capacity to improve firm performance.

This experiment was conducted to investigate the effects of dietary supplementation of various Lactobacilli strains on growth performance, intestinal microflora, ileal villi development and ileal mucosal surface of broiler chickens. Six hundred 1-d-old male chicks(Avian) were randomly divided into five groups of four replicates, each replicates containing 30 birds and fed corn-soybean meal diets containing Latobaillus were isolated from cecum of chichens at 107cfu/g diet for five weeks. The treatments were control(antibiotics-free diet), Lactobacillus crispatus avibro1(LCB), Lactobacillus reuteri avibro2(LRB), Lactobacillus crispatus avihen1(LCH) or Lactobacillus vaginalis avihen2(LVH). The body weight gain in groups fed Lactobacillus significantly improved as compared to those of control(P<0.05). Feed intake was not statistically different among the groups. The number of Lactobacillus in ileum and cecum of chicks fed various Lactobacillus tended to be increased or significantly increased as compared to those of the control(P<0.05), but there was difference by age of chicks and species of Lactobacillus. The number of yeast was significantly increased in cecum and ileum at three weeks old chicks fed Lactobacilli compared with the control(P<0.05). The anaerobes’ number of ileum and cecum tended to increase or significantly increased in Lactobacillus treatments compared with the control(P<0.05). The ileal villi length extended greatly at three weeks of age in groups fed Lactobacillus compared with the control(P<0.05). The length of ileal villi in chicks fed Lactobacillus was continuously increased up to five weeks of age, but did not increased in the control(P<0.05). Lactobacillus was found on ileal mucosal surface. And ileal mucosal surface was maintained better with Latobacillus feeding. These results suggest the possibility that cecal Lactobacillus of chickens could be used as probiotics by improving the growth performance and promoting development of ileal villi in broiler chicks.
