  • Purpose - The purpose of this study is to examine whether the change of settlement procedures have an impact on the distribution of day of the week effect in the UK and French markets or not. U.K and France changed their systems from fixed settlement date systems to fixed settlement lag systems Design/methodology/approach - This study adopted the data of the specific stock market indices such as FTSE 100 in the U.K market and FRCAC 40 in the French market, This study constructs a test of the differences in mean returns across the days of the week by computing the regression equations for each country index. Findings - First, this study found that the evolving settlement procedures in stock exchanges have an effect on stock return of day of the week. Second, long-run improvements in market efficiency may have diminished the effects of certain anomalies in recent periods. Improvements in market efficiency and evolving settlement systems may cause the disappearance of the weekend effect. Research implications or Originality - The Implication of this study is that recent settlement systems contributed to the disappearance of the weekend effect and explains improvements in market efficiency and diminishments of market anomaly. This study may be the first study which examines whether evolving settlement systems have an effect on the disappearance of the weekend effect in the market or not.

  • The objectives of this study were to examine calpain activity and meat tenderness by three different feeding patterns in Korean native cattle (KNC). Total forty-five animals were assigned each fifteen in long term restriction feeding (LTFR), long-term restriction feeding and hormone treatment (LTFR-tH), and short term non-restriction feeding (STFNR), respectively. Concentrate was restricted based on body weight in exp 1 and 2. However, it was fed ad libitum in exp. 3. Hormonal implantation was made with $M-PO^{TM}$ for bulls and with $F-TO^{TM}$ for heifers at 18, 20, 22 months of age in exp. 2. Animals were purchased (3-5 month old) from local cattle market and managed in two local farms and university research unit at three different years. Animals were slaughtered at 24 months for long-term trial and at 18 month for short term-trial. Loin and tender loin muscle was used for calpain activity and meat quality. Calpain proteolytic system was not changed by treatment. However, calpastatin activity was low in short-term trial. The calpain and calpastatin activity is reciprocal relationship, therefore, the high calpain activity may effect on quality grade. The shear force value was decreased as the processing of aging after postmortem. On the other hand, the cooking loss was significantly higher in short-term than in long-term trial, and then gradually decreased by the aging. Hormone implants to increase meat yield influenced to calpastatin activity more powerfully than calpain activity to meat tenderness. In meat color-a*, there was not significant difference in loin. Meat color-b* was decreased as postmortem aging time increased in tenderloin. Western blots were done to learn whether these proteins are degraded during postmortem storage and whether this degradation temporally parallels the decrease of shear force value. Vinculin was detected at 0 day and 1 day and degraded after 3 day. In conclusion, Calpain activity was affected slightly on meat tenderness. But meat tenderness was influenced by calpastatin, more effectively.

  • The pH, acidity, protein, color, reducing sugar, total sugar, alcohol and organoleptic characteristics of Takju containing 100% short grain rice (100 S), 100% long grain rice (100 L), 50 S+50% puffed rice powder (50 P) and 50 L+50 P were examined. After a drastic decrease during the initial stage of fermentation, the pH gradually increased except 100 L. Protein peaked at day 1 and decreased. A higher protein was noticed in puffed samples than in rice samples (p < 0.05). The Hunter "L" value decreased after a rise during the beginning of fermentation. Puffed samples showed higher reducing sugar than rice at day 0. Total sugar was similar to reducing sugar. A drastic increase in alcohol concentration was detected at day 2. Higher alcohol was observed in short grain than long grain and also in puffed samples than in rice (p < 0.05). A significant difference between 100 S and 100 L was observed in a sensory evaluation (p < 0.01); while no preference was detected.

  • A new graphical method was developed to separate two distinctive decay rate coefficients($k_1$ and $k_2$) at their respective degradable substrate fractions($S_1 and $S_2$). The mesophilic batch reactor showed $k_1$ of $0.151\;day^{-1}$ for wasted activated sludge(WAS), $0.123\;day^{-1}$ for thickened sludge(T-S), $0.248{\sim}0.358\;day^{-1}$ at S/I ratio of $1{\sim}3$ for sorghum and $0.155{\sim}0.209\;day^{-1}$ at S/I ratio $0.2{\sim}1.0$ for swine waste, whereas their long term batch decay rate coefficients($k_2$) were $0.021\;day^{-1}$, $0.001\;day^{-1}$, $0.03\;day^{-1}$ and $0.04\;day^{-1}$ respectively. At least an order of magnitude difference between $k_1$ and $k_2$ was routinely observed in the batch tests. The portion of $S_1$, which degrades with each $k_1$ appeared 71% for WAS, 39% for T-S, 90% for sorghum, and $84{\sim}91%$ at S/I ratio of $0.2{\sim}1.0$ for swine waste. Ultimate biodegradabilities of 50% for WAS, 40% of T-S, $82{\sim}92%$ for sorghum, and $81{\sim}89%$ for swine waste were observed.

  • The continuous urbanizations by a rapid economic growth and a steady increase in population are expected to have a possible impact on meteorology in the downwind region. Long-term (1972~2007) trends of precipitation have been examined in the mid-Korean peninsula for the westerly condition only, along with the sensitivity simulations for a golden day (11 February 2009). During the long-term period, both precipitation amount (PA) and frequency (PF) in the downwind region (Chuncheon, Wonju, Hongcheon) of urban area significantly increased for the westerly and light precipitation ($PA{\leq}1mm\;d^{-1}$) cases, whereas PA and PF in the mountainous region (Daegwallyeong) decreased. The enhancement ratio of PA and PF for the downwind region vs. urban region remarkably increased, which implies a possible urbanization effect on downwind precipitation. In addition, the WRF simulation applied for one golden day demonstrates enhanced updraft and its associated convergence in the downwind area (about 60 km), leading to an increase in the cloud mixing ratio. The sensitivity experiments with the change in surface roughness demonstrates a slight increase in cloud water mixing ratio but a negligible effect on precipitation in the upwind region, whereas those with the change in heat source represents the distinctive convergence and its associated updraft in the downwind region but a decrease in liquid water, which may be attributable to the evaporation of cloud droplet by atmospheric heating induced by an increase in an anthropogenic heat. In spite of limitations in the observation-based analysis and one-day simulation, the current result could provide an evidence of the effect of urbanization on the light precipitation in the downwind region.

  • The effects of progesterone releasing intravaginal device (PRID) on the fertility levels in dairy cows were studied in 2 experiments. In experiment I, 70 lactating cows at 45 days postpartum were allotted to 3 groups and the treatments imposed were either: 1: Untreated control, 2: PRID with a capsule containing long of oestradiol benzoate (ODB) attached, inserted for 12 days, 3: PRID inserted for 12 days with long of prostaglandin F$\_$2${\alpha}$/ administration 24 h before PRID removal. Treated cows were inseminated 56 h after PRID removal and at an observed oestrus during the subsequent 48-day period. The control group was inseminated at an observed oestrus during this 60-day period. In experiment II, 60 ovarian disorder cows were divided into 5 groups and PRID+ODB inserted for 12 days. 1: atrophied ovary, 2: smooth ovary, 3: persistent corpus luteum, 4: follicular cyst, 5: luteal cyst. Treated cows were inseminated 56 h after PRID removal and at an observed oestrus over a period from the first insemination to 46 days. The results obtained were as follows: 1. The device produced a vaginal discharge in some animals. In experimenet I : 2. For treatments 2 and 3, respectively, conception rates to the fixed time insemination were 45% and 52%. 3. The conception rates of cows inseminated to the fixed time insemination and at an observed oestrus during a 60-day period were 65%, 86% and 91% for control, treatment 2 and 3, respectively. 4. Mean interval from calving to conception and inseminations per conception were 133, 91 and 86 days and 2.4, 2.1 and 1.9 for control, treatments 2 and 3, respectively. In experiment II; 5. The conception rates to the fixed time insemination for each group 20, 50, 70, 20 and 50%, respectively. 6. The total conception rates for the 48 days period of each group were 60, 70, 100, 60 and 90%, respectively. 7. The inseminations per conception of each group were 2.8, 2.1, 1.4, 2.7 and 1.9, respectively.

  • The effects of herbal medicine on type 2 diabetic animal model were investigated. Herbal medicine were composed with the addition of Coicis Semen into Okchun-san (OCS). Commelinae Herba into Gangsim-tang (GST). Scrophulariae Radix into Hyunsamsunki-san (HSK). and Erythrinae Cortex into Yukmijihuang-hwan (YMH). We evaluated anti-hyperglycemic and body weight reduction activity in diabetic db/db mice. The experimental animals were divided into six groups. as control group and five sample groups. Each 200mg/kg/day of OCS, GST, HSK and YMH was administered with orally for 14days long. 5mg/kg/day of acarbose was administered with orally for 14days long. On day 14, OCS-treated db/db mice had significantly lower fasting blood glucose levels compared to control group(296±25.9 versus 593±16.4mg/dl. p<0.001). During the 2 h intraperitoneal glucose tolerance test (IPGTT), all the sample groups were improved compared to control group but insignificantly. After 14days of extract treatment. body weight in control. YMH and acarbose groups were increased. but OCS. GST and HSK groups reduced. However. it did not significantly lower hemoglobin Alc(HbAlc) in blood of db/db mice. These result suggest that OCS could be effective on insulin-independent type 2 diabetes.

  • Lightweight geopolymers were fabricated by using IGCC (integrated gasification combined cycle) slag and Si sludge which are classified as general wastes (recyclable resources). Three curing methods were tried to investigate the changes in compressive strength and density according to the curing method and immersion time. Immersion period was tried up to 21 days to observe long-term performance in water. Compressive strength of the specimens cured in oven decreased abruptly with an increase in immersion time. Compressive strength of the specimen cured in autoclave was low after 3 and 7 day immersion; however, increased rapidly after 21 day immersion. On the contrary, compressive strength of the specimen cured in autoclave and oven was high but substantially decreased after 21 day immersion. Conclusively, it was speculated that oven curing is effective for the compressive strength development at early age; however, autoclave curing is more desirable for the long-term performance in water.

  • Background: Meloxicam is used widely for exotic animal analgesia, but its toxicity in common raptor species in Thailand is unclear. Objectives: This study evaluated the single-dose effect of intramuscular meloxicam in common raptor species in Thailand for short-term and long-term periods. Methods: Twenty-two raptors were administered a single 1 mg/kg dose of meloxicam individually via intramuscular injection. The following were evaluated: clinical appearance, body weight, body condition score, body temperature, fecal appearance, complete blood cell count, and biochemistry panel before (day 0) and after the injection (1, 7, and 30 days). The collected samples were categorized into three groups: Brahminy kite (Haliastur indus) (n = 10), adult Barn owl (Tyto javanica) (n = 4), and juvenile Barn owl (n = 8). Results: None of the raptors in the study groups showed any abnormalities. The hematological profiles were significantly different in the short-term period (day 1 and day 7). The creatinine, aspartate aminotransferase, and creatinine kinase increased in several groups. On the other hand, the packed cell volume decreased in the Brahminy kite and juvenile Barn owl groups. According to the findings, an intramuscular injection of 1 mg/kg meloxicam affected the blood biochemistry panel of the muscle, but the affected raptors recovered within one week. Conclusions: An intramuscular injection of meloxicam at a single 1 mg/kg dose in Brahminy kites and Barn owls was not associated with the morbidity, hepatotoxicity, gastrointestinal toxicity, and nephrotoxicity in the short- and long-term periods.

  • The purpose of this study is to explore the process for the elderly with palsy to solve conflicts with the elderly with dementia in day care center through the narrative therapy group work. For this, the researcher enacted the Narrative therapy group work on the 12 elderly with palsy for seven sessions, and analysed these data through qualitative case study method. The results of this study are as follows. First, the elderly with palsy became to recognize the elderly with dementia as 'the people suffering from dementia' rather than 'the problem', and tried to care them rather than to blame. Second, they became to recognize themselves as 'component people' rather than 'the victim'. Third, they grew intimate and collaborated with themselves. Fourth, they participated actively in day care center. It was discussed connection between these changes and narrative therapy skills, such as to separate problem from people, to respect client as expert for one's problem, to seek unique outcome. The recommendation is suggested that it is important to enlarge choice to participate for long-term care service consumer and to apply narrative therapy on the elderly.
