  • To determine availability as a feed source of deer of by-products that produced at reforestation areas and comprised shrubs and wild grasses, mixed forest by-product silage(FBS), arrowroot silage(ARS), bristletooth oak tree silage(BOS), white oak tree silage(WOS) were prepared to compare dry matter intake, digestibility and nitrogen balance in digestion balance trials with spotted deer. Dry matter intake was highest in WOS and lowest in ARS but there was no significant difference(P>0.05). Digestible dry matter intake was higher in FBS and ARS that had higher dry matter digestibility than in WOS and BOS that had lower dry matter digestibility(P>0.05). Dry matter digestibility was highest fur ARS and lowest for BOS(P<0.05). Digestibility of crude protein was similar to that of dry matter. That of crude fiber was higher for FBS and ARS than for BOS and WOS(P>0.05). Daily gain of body weight was slightly greater for WOS than fer other treatments(P>0.05). Nitrogen intake was highest for ARS and lowest for BOS(P<0.05), and fecal nitrogen was opposite to nitrogen intake(P<0.05). Nitrogen excretion with urine was highest for ARS that had higher nitrogen intake and lowest for BOS and there was a significant difference(P<0.05). Retained nitrogen was highest for FBS and lowest for. BOS (P>0.05). Although there was no significant difference(P>0.05): the ration of nitrogen intake to retained nitrogen was highest in FBS for 43.9% and lowest in BOS for 24.7%. Consequently because by-products that produced at reforestation areas had high intake and internal availability, it was evaluated to valuable feed source for deer.

  • Present experiment was carried out to determine maintenance energy requirements for growing Hanwoo steers. Six Hanwoo steers (BW = $180.6{\pm}3.1$ kg) were used in two 3 ${\times}$ 3 latin square design with three different energy intake levels; TDN 1.70 kg (Low), 2.05 kg (Medium), 2.80 kg (High), respectively, based on the Korean Feeding Standards. Each period lasted 18 days including a 14-day adaptation and a 4-day measuring period. The steers were in the head hood chamber system (one cattle per chamber) during each measuring time to measure heat and methane production for 1 day. Dry matter intake was 2,058, 3,256 and 3,881 g/day for Low, Medium and High TDN, respectively. Increase in energy intake did not affect digestibilities of dry matter, crude protein, crude fiber, crude fat, NDF, ADF and nitrogen-free extract. Gross energy intake averaged 180.21, 292.74 and 337.15 kcal/$BW^{0.75}$ for Low, Medium and High TDN, respectively. Energy loss was 28.7% in feces and 2.1% in urine of gross energy intake. Further, energy loss from methane produced during rumen fermentation was 6~8.3%, while body heat loss averaged 34~60%. Intercept of regression equation between ME intake and retained energy indicated that the energy requirement was 109.84 kcal ME/$BW^{0.75}$.

  • The removal yield of dissolved organic matter in drinking water by biological activated carbon (BAC) process was investigated. The tested processes wer raw water-AC process (BAC1), raw water-ozonation-BAC process (BAC2), and raw water-ozonation-coagulation/sedimentation-BAC process (BAC3). The amounts of organic matter was measured as dissolved organic carbon (DOC), ulta-violet radiation at 254 nm wavelength ($UV_{254}$), total nitrogen (T-N), ammonia nitrogen (NH_3$-N), and total phosphate (T-P). As a results, 30.7% DOC was removed by BAC2 process, which showed higher removal efficiency than BAC1 or BAC3 processes. The removal yield of $UV_{254}$ in BAC1, BAC2, and BAC3 processes were observed as 45.3%, 44.6%, 58.4%, respectively. And the removal yield of ammonia nitrogen were 66%, 81%, 29% in each BAC processes. The optimal empty bed contact time (EBCT) of BAC processes was estimated as 10 minute. This study has shown that BAC process combined with ozone treatment was efficient for removing dissolved organic matter in water.

  • Mean concentration of 2 artificial sweeteners, sodium saccharin and acesulfame K, in food samples and their daily intakes were estimated. Among 755 food samples, 57 contained these artificial sweeteners. Contribution rate to total estimated daily intake (%) of artificial sweeteners in food categories were high in danmooji for sodium saccharin and ice cream for acesulfame K. Total estimated daily intakes $({\Sigma}EDI)$ for different age groups were high in 30-49 year-old group for sodium saccharin and 13-19 year-old group for acesulfame K. Total estimated daily intakes $({\Sigma}EDI)$ of men and women were 5.91 and 4.89 mg/man/day, respectively. Total estimated daily intakes $({\Sigma}EDI)$ based on mean body weight of 55 kg were 4.13 and 1.25 mg/man/day for sodium saccharin and acesulfame K, respectively. These values ranged within 0.2-1.5% of acceptable daily intake (ADI) evaluated by FAO/WHO and 1.2-13.5% of theoretical maximum daily intake (TMDI), and, therefore, judged to be safe.

  • This study was evaluated high end research grade Near infrared spectrophotometer (NIRS) to low end popular field grade multiple Near infrared spectrophotometer (NIRS) for rapid analysis at forage quality at sight with 241 samples of Italian ryegrass silage during 3 years collected whole country for evaluate accuracy and precision between instruments. Firstly collected and build database high end research grade NIRS using with Unity Scientific Model 2500X (650 nm~2,500 nm) then trim and fit to low end popular field grade NIRS with Unity Scientific Model 1400 (1,400 nm~2,400 nm) then build and create calibration, transfer calibration with special transfer algorithm. The result between instruments was 0.000%~0.343% differences, rapidly analysis for chemical constituents, NDF, ADF, and crude protein, crude ash and fermentation parameter such as moisture, pH and lactic acid, finally forage quality parameter, TDN, DMI, RFV within 5 minutes at sight and the result equivalent with laboratory data. Nevertheless during 3 years collected samples for build calibration was organic samples that make differentiate by local or yearly bases etc. This strongly suggest population evaluation technique needed and constantly update calibration and maintenance calibration to proper handling database accumulation and spread out by knowledgable control laboratory analysis and reflect calibration update such as powerful control center needed for long lasting usage of forage analysis with NIRS at sight. Especially the agriculture products such as forage will continuously changes that made easily find out the changes and update routinely, if not near future NIRS was worthless due to those changes. Many research related NIRS was shortly study not long term study that made not well using NIRS, so the system needed check simple and instantly using with local language supported signal methods Global Distance (GD) and Neighbour Distance (ND) algorithm. Finally the multiple popular field grades instruments should be the same results not only between research grade instruments but also between multiple popular field grade instruments that needed easily transfer calibration and maintenance between instruments via internet networking techniques.

  • The new system on the Corporate Social Responsibility(CSR) in the Indian Companies Act became overnight sensation to the worldwide. However there has been very few studies which are analyzing a purpose of it under the context of Indian societies. This paper examines the circumstance whether the CSR activities is functioning well or not. And verifying problems regarding it and suggesting supportive measures are a target of this paper. Though Indian government already established CSR legislation, they did not stipulate the penalty clause. And that became why corporations were poorly perform on CSR activities in first year of enforcement. Furthermore, There is a proclivity that corporations lack an understanding for which activities could be recognized into the CSR. And they excused that they had no time for themselves to adjust an abruptly changing business landscape. With all, unlike rosy expectations, corporations only showed little interests to the area where the investment or attentions from the media are expected. Fortunately, incumbent legislative is fully aware of it and exploit their best resources to various social fields. Despite the doubts that they originally did not have any intention to introduce the penalty clause, they are handling problems in ways that corporations can be invited in public programs. They also need to request the service sectors to take a leading role of it, which could provide the financial, or telecommunication service to the people in rural province. Thus, the fact that there was a substantial rise in terms of the amount of CSR expenses in 2015 provides a supporting evidence to the endeavors of the government. In doing so, we could finally achieve a better understanding of two-fold goals shown in this paper; maturing settlement of this legislation and development of Indian society.

  • Interest in edible insects such as Protaetia brevitarsis has increased rapidly, and several insect producers use these insects in industrialized mass production. However, mass rearing of insects can cause insect diseases. Sprouted barley is a valuable source of nutrients and has antioxidant, antimicrobial, anti-inflammatory, and anti-cancer effects. This study was conducted to investigate the effect of sprouted barley as a feed additive for producing healthy P. brevitarsis larvae. P. brevitarsis larvae were fed feeds with or without sprouted barley, and their body weight and larval period wewe checked weekly. To confirm the antibacterial effects of sprouted barley, in vitro bioassays were performed by counting Serratia marcescens colonies, and in vivo bioassays were performed by determining the survival rate and body weights of the S. marcescens-infected larvae. Larvae fed different feeds were analyzed for their nutrient compositions (i.e., such as proximate composition, minerals, amino acids, and heavy metals). Larvae fed 5% and 10% sprouted barley had maximum weight increases of 19.2% and 23.1%, respectively. Both treatment groups had significantly shorter larval periods than those of the control group. Sprouted barley markedly inhibited the growth of entomopathogenic S. marcescens. Furthermore, larvae fed sprouted barley exhibited higher Cu, Zn, and K levels. Seventeen amino acids were present in larvae fed sprouted barley, of which, tyrosine and glutamic acid were predominant. No heavy metals were detected in any of the investigated groups. Therefore, sprouted barley may be a suitable feed additive for producing high-quality P. brevitarsis larvae.
