  • An in situ ruminal disappearance trial and an in vivo sheep metabolism trial were conducted to evaluate the nutritional value of spent mushroom substrate (SMS, originated from Pleurotus osteratus bed-type cultivation). The raw SMS was ensiled (ESMS) for 30 days with 5% (w/w, DM basis) molasses, 0.5% (v/w) yeast (Saccharomyces cerevisiae) and 0.5% (v/w) lactic acid bacteria (Lactobacillus plantarum). Two ruminally cannulated Holsteins (average BW 620 kg) were used to evaluate in situ disappearance. Six sheeps (average BW 48 kg) were fed, in $3{\times}3$ Latin square design, rice straw alone (Control), 25% (ESMS-25) and 50% (ESMS-50) of rice straw were replaced with ensiled SMS. For an in situ trial, ruminal DM and neutral detergent fiber (NDF) disappearance of SMS were increased after ensiling (P<0.05). For a sheep trial, protein and fiber (NDF, acid detergent fiber, crude fiber) digestibilities were decreased (P<0.05), crude ash digestibility was increased (P<0.001), and nitrogen retention was not affected (P>0.05) as rice straw was replaced with ensiled SMS. Ruminating time was decreased by an average of 28% by feeding ensiled SMS (P<0.05). Ensiled SMS (Bed-type cultivation) had 76% of energy value of rice straw. Consequently, ensiled SMS (Bed-type cultivation, 100% cotton waste) could be used as a roughage source appropriate for maintenance type rations for ruminants.

  • Purpose: The purpose of this paper is to identify a theoretical basis of end-of-life care by examining attributes of the concept of the nurses' acceptance of patient deaths. Methods: Walker and Avant's approach to concept analysis was used. A literature study was performed to check the usage of the concept. To identify the attributes of the concept and come up with an operational definition, we analyzed 16 qualitative studies on nurses' experiences of death of patients, published in a national science magazine from 1999 to 2015. Results: The nurses' acceptance of death of patients was identified as having four attributes: acceptance through mourning, attaining insight on life and death while ruminating life, facing with fortitude and practicing human dignity. Antecedents of the concept were experiences of patient's death, confusion and conflict, negative emotions, passive responses, denial of patients' death. The consequences of the concept were found as the holistic end-of-life care and active pursuit of life. Conclusion: This study on the attributes of the concept of the nurses' acceptance of death of patients and it's operational definition will likely lay the foundation for applicable end-of-life care mediations and theoretical development.

  • Objective: The study aimed to evaluate sugarcane bagasse as roughage in lactating cow on feed intake, digestibility, ingestive behavior, milk production and composition, and microbial protein synthesis. Methods: Ten Girolando cows at initial body weight of $450{\pm}25.6kg$ and at $143.7{\pm}30.7days$ in milk were assigned in two $5{\times}5$ Latin square designs. Five 21-day experimental periods were adopted ($1^{\circ}$ to 14-day: diets adaptation period; $15^{\circ}$ to 21-day: data collection and sampling period). The diets consisted of four different levels of sugarcane bagasse (45%, 50%, 55%, and 60%) and a control diet, commonly adopted in the region, based on spineless cactus (25% sugarcane bagasse), formulated to meet 12 kg/d milk yield. Results: The dry matter (DM), organic matter (OM), and total digestible nutrients intakes and DM and OM digestibilities observed for 45% and 50% bagasse inclusion were similar to control diet, while that 55% and 60% bagasse inclusion were lower. Cows fed control diet, and bagasse diets of 45%, and 50% levels had the nutritional requirements attended, that guaranteed 12 kg/d of milk yield. The crude protein intake and digestibility of cows fed 45%, 50%, and 55% of bagasse inclusion were similar to control diet. The neutral detergent fiber (NDF) intake and digestibility differ for all bagasse diets related to control diet, while the non-fiber carbohydrates intake and digestibility for cows fed 45% of bagasse were similar for control diet. The intakes and digestibilities of nutrients decreased linearly in function of bagasse inclusion; NDF and indigestible NDF intakes did not vary. The ruminating time, feeding and rumination efficiency, microbial protein synthesis and milk yield decreased linearly with sugarcane bagasse inclusion. Conclusion: Sugarcane bagasse decreases milk production; however, its inclusion level in between 45% to 50% associated to concentrate could replace diets based on spineless cactus for crossbred dairy cow's producing 12 kg/d of milk.

  • Effects of increasing dietary rice straw on chewing activity, ruminal fermentation, and fibrolytic enzyme activity in growing goats were investigated in a $4{\times}4$ Latin Square experiment. The goats were offered four diets with an increasing proportion of rice straw (i.e. 0.05, 0.10, 0.15 and 0.20, respectively, on dry matter basis). Increasing level of rice straw increased ($P_{linear\;effect}$ <0.05) the time spent on eating, ruminating, and chewing. The ruminal pH and acetate: propionate ratio were increased ($P_{linear\;effect}$ <0.05), while the $NH_3$-N concentration was decreased ($P_{linear\;effect}$ <0.01). Increasing level of rice straw in the diet increased ($P_{linear\;effect}{\leq}0.01$) molar proportion of acetate and isovalerate, and decreased ($P_{linear\;effect}$ <0.01) molar proportion of propionate. The CMCase, xylanase and cellobiase activities in the rumen were decreased ($P_{linear\;effect}$ <0.05) with increasing level of dietary rice straw, whereas the avicelase activity was increased ($P_{linear\;effect}$ <0.01). In summary, increased level of rice straw elevated the dietary neutral detergent fibre (NDF) content in the diet and had a great impact on chewing activity and ruminal fermentation.

  • Twenty-four yearling Boer$\times$Spanish goats were used in a crossover design experiment to determine effects of tethering on forage selection, intake and digestibility, grazing behavior and energy expenditure (EE) with forage high in nutritive value and low to moderate in mass. Objectives were to determine if tethered goats could be used as a model for study of unrestrained animals and to characterize tethering as a production practice. Four 0.72-ha pastures of wheat (Triticum aestivum) and berseem clover (Trifolium alexandrium) were grazed in December and January. Each pasture hosted six animals, three with free movement and three attached to a 4.11-m tether for access to a circular area of $53.1m^2$. Tethering areas were moved each day. One animal of each treatment and pasture was used to determine forage selection, fecal output or grazing behavior and EE; therefore, there were eight observations per treatment. Mass of forage DM before grazing in Tethered areas averaged 1,280 and 1,130 kg/ha in periods 1 and 2, respectively. The CP concentration in ingesta was greater ((p<0.05) 239 and 209 g/kg; SE = 8.0) and the NDF level was lower (p<0.05) for Free vs. Tethered animals (503 and 538 g/kg; SE = 12.0); in vitro true DM digestion was similar between treatments (0.808 and 0.807 for Free and Tethered, respectively; SE = 0.0096). Intakes of DM (1,013 and 968 g/d; SE = 78.6), NDF (511 and 521 g/d; SE = 39.9) and ME (10.9 and 10.7 MJ/d; SE = 0.90) were similar between treatments, but CP intake was greater (p<0.05) for Free vs. Tethered animals (241 and 203 g/d; SE = 17.2). There were small treatment differences in in vivo apparent digestibility of OM ((p<0.05) 0.780 and 0.814; SE = 0.0049), CP ((p<0.05) 0.800 and 0.817; SE = 0.0067) and NDF ((p<0.09) 0.777 and 0.760 for Free and Tethered, respectively; SE = 0.0078). There were no treatment effects on time spent ruminating or grazing (346 and 347 min/d for Free and Tethered, respectively; SE = 42.5), but EE was considerably greater (p<0.05) for Free vs. Tethered animals (571 and 489 kJ/kg $BW^{0.75}$; SE = 8.9). In conclusion, with forage of high nutritive value and low to moderate in mass, tethering can offer a production advantage over free grazing of less energy used for activity despite similar grazing time. With forage removal considerably less than that available for grazing, effects of tethering on chemical composition of selected forage were small and less than needed to markedly affect digestion. Tethering may offer a means of studying some aspects of grazing by ruminants, but would not seem suitable for energy metabolism.

  • The objective of this study was to determine the effects of physically effective neutral detergent fiber (peNDF) content in total mixed ration (TMR) on dry matter intake, digestibility, and chewing activity in fattening Hanwoo (Bos taurus coreanae) heifers. The experiment was designed as a replicated $3{\times}3$ Latin square using 12 heifers. Fattening heifers were offered one of three diets [high (T1), medium (T2), and low (T3) peNDF] obtained by different mixing times (3, 10, and 25 min) for the same TMR feed. The peNDF content of TMR was determined by multiplying the proportion of dry matter retained by a 1.18 mm-screen in a Penn State Particle Separator by the dietary NDF content. The $peNDF_{1.18}$ content was 30.36%, 29.20%, and 27.50% for the T1, T2, and T3 diets, respectively (p<0.05). Dry matter intake was not affected by peNDF content in TMR. Total weight gain in T1 group was significantly higher (p<0.05) than in T2 and T3 groups. However, weight gain did not differ between T2 and T3 groups. The feed conversion ratio decreased with an increase in the peNDF content (T1: 12.18, T2: 14.17, and T3: 14.01 g/g). An increase in the peNDF content of TMR was associated with a linear increase in the digestibility of dry matter, crude protein, crude fiber, neutral detergent fiber, and acid detergent fiber (p<0.05). Also, an increase in peNDF content of the TMR resulted in a linear increase in the number of chews in eating and ruminating (p<0.05), and consequently in the number of total chews (p<0.05). These results indicate that peNDF content affects digestibility and chewing activity. Consequently, the peNDF content of TMR should be considered for improving feed efficiency, digestibility, body weight gain, and performance in fattening heifers.

  • Objective: This research analyzed behavioral characteristics of Hanwoo (Bos taurus coreanae) steers during each season and growth stage to enable measurement of the animals' welfare level for precision livestock farming. Methods: A hundred-eight beef steers were divided into three equal groups at a Hanwoo farm according to their growth stage: growing stage (GS), 8 months; early-fattening stage (EFS), 19 months; and late-fattening stage (LFS), 30 months. Twelve behavioral categories were continuously recorded for 13 day-time hours in each four seasons with three replications. Results: Time spent standing was found to be significantly longer in summer at all growth stages (p<0.05). Hanwoos at the GS spent significantly longer standing time in spring and summer than those at the EFS and LFS (p<0.05). Lying time in summer was the shortest for all growth stages (p<0.05). Steers at the LFS spent significantly longer lying time than that at the GS (p<0.05) in summer. For GS and EFS, time spent eating in spring and autumn were longer than in summer and winter (p<0.05). Eating time was the longest for the GS in spring, autumn, and winter, excluding for the LFS in winter (p<0.05). Regarding ruminating, steers at the LFS spent significantly shorter time than those at other stages in all seasons (p<0.05). GS and EFS steers showed the longest walking time in summer compared with other seasons (p<0.05). At GS and LFS, drinking time in summer was the longest of all seasons (p<0.05). Sleeping time was significantly shorter in summer compared with the other seasons (p<0.05). Self-grooming time was the longest in winter for all growth stages (p<0.05). Conclusion: Steers were found to have more variable behavioral patterns during summer and the GS and less active behaviors during the LFS, thus extra care seems necessary during the GS, LFS, and summer period.

  • In the 17th and 18th centuries, when the Ryukyu kingdom had been invaded and controlled by Japan, some official texts about 'history' were documented. In that texts, there are some myths about the kings-Syunten(舜天), Eiso(英祖), Satto(察度), Syouhasi(尙巴志), Syouen(尙圓)-who founded dynasties of Ryukyu kingdom. This study attempts to delineate the features and meaning of those founder myths as a polotial discourse for kingship. The results of this study are as follows. 1. The founder myths are discourses to describe the genealogy of the Ryukyu kingdom as the result of Mandate of Heaven(T'ien Ming, 天命). 2. In ancient okinawa, the sun was a symbol of ruler. The king of Ryukyu kingdom was thought as 'son of the sun', 'Tedako(てだこ, 太陽子) in the time of Syou dynasty(尙王朝). But in the founder myths, the only one Tedako is Eiso. 3. In the myths, the 'historical' founders are described as the king for agriculture. They were said to make the farming instruments with iron and rule the spring water for farming. The iron and water for fariming was thought to represent the power of king and the kingship. 4. The writers of myths aimed to be separated from the mythical kingship of past Ryukyu(古琉球). So, they threw the idea of Tedako(=mythical kingship) into the prison of mythical ages by rewriting myth of King Eiso. Instead of it, they built up the new image of agriculture-king who rules and controlls the iron and water for good farming. The meaing of this change, from 'shiny sun' to 'cultural king', is that the abstract and general power of kingship was turned into a concrete and restricted power of kingship. On the bases of it, there was the confucian political ideas from China, T'ien Ming thought(天命論). Under the influence of not only China but also Japan, the writers of myths attempt to find a new way for their kingdom by reconstructing kingship with ruminating over the kingship of past. The myth of founders in the 17th and 18th Centuries shows the aspects of kingship of Ryukyu kingdom and tells us that those myths are the political discourses identifying kingship and Ryukyu kingdom.

  • This study was conducted to verify the effects of socially prescribed perfectionism on depression as mediated by intolerance of uncertainty and either ruminating or reflective response styles, on as will as to find ways to effectively address depression as it presents in university students. For this purpose, 283 university students at the central region were assesed using data collected from the following surveys: the Center for Epidemiological Studies-Depression Scale(CES-D), the Multidimensional Perfectionism Scale(HMPS), the Intolerance of Uncertainty Scale(IUS), and the Response to Depressed Mood Questionnaire(RDQ) and that were used to collect data. The results of this study are as follows. First, there was a positive correlation between the Intolerance of uncertainty and the rumination response style to the uncertainty of socially prescribed perfectionism, but not correlation the reflective response mode. Second, with respect to the relationship between socially prescribed perfectionism and depression, intolerance of uncertainty was set as the primary mediator variable and the rumination response style were set as the secondary mediator variables. The results shown to have a significant mediating effects. However this mediating effect was not significant when, in order to verify the mediating effect, we set the secondary mediator variable as the reflective response style. These results suggest that to prevent depression that manifests as socially prescribed perfectionism, it may be effective to intervene with a focus on the intolerance of uncertainty and the rumination response style. Finally, the implications and limitations of the study are discussed based on the results.

  • This study is on the creation of floral art works based on the intuitive insight acquired by methodological process of ruminating the experienced meaningful events of the artists utilizing sensible perception. The researcher used the narration and visualization techniques. The narration process adopted the writing technique of subjective impression, emotion, stream of consciousness to capture sensations of subconscious state, which were applied in three steps of 'the exploration of experiences', 'the concretion of experiences', and 'the creation of meaning out of experiences'. The visualization process adopted collection, selection, classification, and interpretation of related images, which were applied in three methods of 'the creation of images', 'the utilization of intuition', and 'the perception through remembering'. Finally 5 art works of 'Hammock is Good', 'At the Rooftop with Warm Sunshine', 'Standing at the Waterside Alone', 'Dizziness at Hot Sand Field', and 'Having Good Time at a Botanical Garden'were created through the combination of these two methods mentioned above and complementary research and writing. The meaningfulness of this research lies in presenting methodological approaches of utilizing narration and visualization of experiences in art creation process.
