  • The objective of this study was to evaluate the effect of electric fan installation for milk production improvement of dairy cattle in Thailand. The study was conducted using 2 small-holder dairy farms in Chiang Mai province, during April to August 2004. Electric fans were installed in front of each row of cows. Each of the two rows of cows in the barn was defined as an experimental unit, thus each farm had two experimental units. The fans were operated alternately in 7-day intervals between rows of cows within each farm during the day or between 8.00 am to 8.00 pm. Non-operation periods were used as control. Milk yields were recorded. Data on environmental temperature and humidity were obtained from Chiang Mai Meteorological Center. Result from statistically analysis of milk record suggested an interaction between lactation period and fan installation. Therefore, this interaction term of lactation period and fan installation (PERIOD_FAN) was added as a variable to the regression model. Due to the repeated data collection of milk yield from the same cow (alternate week), milk yield was analyzed by repeated measure analysis (Mixed model). Least square means were calculated for all levels and used to compare between each pair-wise values. The final data were collected from the total of 18 cows with 2,072 data. Overall means and SEM of milk yields and days in milk separated into farm were $14.7{\pm}0.06kg/day$ and $176.3{\pm}2.2days$, and $15.2{\pm}0.22kg/day$ and $202.5{\pm}3.7$ days for farm A and farm B, respectively. For multivariable analysis, only PERIOD_FAN and humidity were significantly associated with milk yield. Only the first period of lactation showed that the amount of milk yields during fan installation was higher than that of non-fan installation (p<0.05). Cows with fan installation produced approximately 1.2 kg/cow more milk than cows without fan installation during this period. In conclusion, the use of electric fan operated during the day time increased milk production of cows during the first period of lactation.

  • Next generation memory technologies, which we denote as 'new memory', have both non-volatile and byte addressable properties. These characteristics are expected to bring changes to the conventional computer system structure. In this paper, we propose a fast boot technique for hybrid main memory architectures that have both new memory and DRAM. The key technique used for fast booting is write-tracking. Write-tracking is used to detect and manage modified data detection and involves setting the kernel region to read-only. This setting is used to trigger intentional faults upon modification requests. As the fault handler can detect the faulting address, write-tracking makes use of the address to manage the modified data. In particular, in our case, we make use of the MMU (Memory Management Unit) translation table. When a write occurs to the boot completed state, write-tracking preserves the original state of the modified address of the kernel region to a particular location, and execution continues. Upon booting, the fast booting process restores the preserved data to the original kernel region allowing rapid system boot-up. We develop the fast booting technique in an actual embedded board equipped with new memory. The boot time is reduced to less than half a second compared to around 15 seconds that is required for the original system.

  • Purpose: This study was to develop a stress-adaptation model for family caregivers of cancer patients that could provide the basis of planning nursing intervention. Method: A hypothetical model was developed using the family adaptation model proposed by Haley et al. (1987). In the literature, the stressor was identified as patient's characteristics, caregiver's characteristics, duration of illness, and family life events. It affected stress appraisal, family resources, family coping and finally caregiver's adaptation. In this model, 18 paths were constructed. Data were collected from 241 caregivers, whose family members were in treatment between June and August 2000, at 3 university hospitals and were analyzed by SPSS and LISREL programs. Results: 1) The overall fitness indices of the hypothetical model were x 2=267.78 (P= .0), GFI= .92, AGFI= .87, NFI= .93, NNFI= .93, PNFI= .64, PGFI= .55, and RMR= .43. Ten of the eighteen paths proved to be significant. 2) To improve the model fitness, the hypothetical model was modified considering modification indices and the paths proved not significant. Final model excluded 3 paths demonstrated to be improved by x2=161.96 (P= .00), GFI= .95, AGFI= .91, NFI= .96, NNFI= .96, and RMR= .23. Twelve of fifteen paths proved to be significant. 3) Stress appraisal was influenced by disease related characteristics and duration of illness and was explained 22% of the variance. Family resources were influenced by stress appraisal and was explained 57% of variance. Family coping was influenced by disease related characteristics, caregiver's characteristics, duration of illness, family life event, and stress appraisal and was explained 57% of variance. Family caregiver adaptation was influenced by disease related characteristics, caregiver's characteristics, stress appraisal, and family coping and was explained 31% of variance. Twelve of fifteen paths were significant. Conclusion: Based on this study, to help family caregivers to adapt, individual intervention is necessary with consideration of disease related and caregiver's characteristics and duration of illness. The intervention should include efforts to raise the family resources and to identify positively the stress they encounter, and there is a need to establish an adaptation model that considers emotional aspects of family caregivers. Since there is a difference in emotional status depending on the disease stage, a study needs to be done to analyze the differences among the disease stages (diagnosis, treatment, recurrence, and terminal stages).

  • The behavior of conger eel, Astroconger myriaster (Brevoort), to the bamboo and plastic pots with baits was investigated alternately in two experimental water tanks. One of the pots being dropped on the tank bottom, the eels touched it to obtain the bait probably by their sense of smell, and increased rapidly in the number of touch to show a maximum within 30 minutes. But the touch was made mainly to the pot wall at which the bait was located and quite accidentally to the pot mouth. The eels touched the pot mouth retreated frequently without attempting to enter the pot and their entering was very hampered by the bamboo funnel constituting the pot mouth. However, a entering, if made, encouraged other touches and the touches ascribed other enterings. But, if 30 minutes elapsed, the number of touch decreased gradually and so the enterings were little made. The ability of pots attracting the eels into them was varied with their inclination to the tank bottom and the bait position in them. That is, the pot which was laid horizontally showed high ability of attracting in case in which the bait was fixed in the vicinity of its mouth. The pot, inclined by $30^{\circ}$ by lifting its tail and had a bait left free, showed almost equal ability to the horizontal pot with a bait in the vicinity of mouth. But the pot, inclined by $30^{\circ}$ by lifting its mouth and had a bait left free, showed a very low attracting. A comparison between the bamboo and plastic pots gave only that the entering of the eels became later several minutes in the latter.

  • Osteoporosis, a disease characterized by low bone mass and microarchitectural deterioration of bone tissue leading to enhanced bone fragility and fracture risk, is a major public health problem. The diagnostic methods for osteoporosis include simple radiography, bone scan, DXA (Dual energy X-ray Absortiometry) and biochemical markers of bone turnover. Optimal treatment and prevention of osteoporosis require modification of risk factors, particularly smoking cessation, adequate physical activity, and attention to diet, in addition to pharmacologic intervention. The estrogens and raloxifene both prevent bone loss in postmenopausal women, and the estrogens probably also decrease the risk of first fracture. There is good evidence that raloxifene prevents further fractures in postmenopausal women who already have had fractures and some evidence that estrogen does as well. Bisphosphonate prevents bone loss and reduces fractures in healthy and osteoporotic postmenopausal women and in osteoporotic men as well. Risedronate is more potent and has fewer side effects than alendronate and reduces the incidence of fractures in osteoporotic women. Calcitonin increases bone mineral density in early postmenopausal women and men with idiopathic osteoporosis, and also reduces the risk of new fractures in osteoporotic women. All of the agents discussed above prevent bone resorption, whereas teriparatide and strontium increase bone formation and are effective in the treatment of osteoporotic women and men. New avenues for targeting osteoporosis will emerge as our knowledge of the regulatory mechanisms of bone remodeling increases, although issues of tissue specificity may remain to be addressed.

  • Degradative Solidification/Stabilization(DS/S) is a modification of conventional Solidification/Stabilization(S/S) that incorporates degradative processes for organic contaminant destruction with the low cost of conventional S/S. Inorganic contaminants are immobilized and chlorinated organic contaminants are destroyed by DS/S treatment. In this study, a DS/S using cement/slag/Fe(II) systems as binder was investigated to assess its effectiveness in degrading chloroform(CF) and methylene chloride(MC) contained in hazardous liquid wastes. The initial concentration of CF was 0.26 mM, 1.0 mM, 8.4 mM, 25 mM and 42 mM and Fe(II) was 200 mM. The result showed that degradation of CF in various concentration was in one kind reaction as pseudo-first-order and 95% of 0.26 mM initial concentration of CF was removed in five days. 50 mg/L of heavy metal was added in order to accelerate the rate of degradation of MC and initial concentration of MC was 3.50 mM however, degradation did not occur in system. Thus additional studies needed for degradation of MC and more studies on other reaction pathways products will help elucidate reaction mechanisms and pathways for chlorinated methanes in cement/slag/Fe(II) systems.

  • This study is on the variation of characters' role and desire in the series animation. For this study, Greimas Actant Model is used to analyze characters' role and behavior and Maslow's Motivation Theory is used to analyze the changing pattern in their desire. Finally, Joseph Campbell's Monomyth or Hero's Journey is used to analyze the whole narrative through all the series. For this analysis, this study chose series animation as a case, The study shows that the desire of the protagonist of series animation keeps escalating for higher values. On the contrary, the other characters' desire don't show any consistency. This result can be explained with monomyth frame. The escalation of the desire in natural because the whole series is a three consecutive episodes about the story of a person's turning over a new leaf and reunion of the parted family. Also, the escalation is originally plotted by the protagonist's expectation role in monomyth's three steps; self-awareness, accomplishment and ultimate freedom.

  • The previous study showed that die-back of apple trees caused by soil-borne diseases was significantly high in the apple orchards in Chungbuk province. The correlation between dieback ratio and cultivation environment in apple orchards infected by soil-borne diseases was investigated in this study. The dieback ratio of five orchards diseased by violet root rot and five places infected by white root rot showed significantly positive correlation with Ca content and available $P_2O_5$ content in soil, respectively. Whereas, the dieback ratio of fourteen orchards diseased by Phytophthora root rot was not significant. Subgrouping of cultivation environment analysis showed that the slope degree of orchard and the number of fruit setting also affected the dieback ratio caused by violet root rot and Ca content in soil also affected the dieback ratio caused by white root rot. It showed that the slope degree, soil texture, Mg and Ca content affected the dieback ratio caused by Phytophthora root rot. These results can be applied to reduce die-back ratio by the modification cultivation environment for each soil-borne disease.

  • Between 1988 and 1992, seven patients with overt meningeal leukemia who had received adequate central nervous system (CNS) prophylaxis were treated with intermittent craniospinal irradiation and intrathecal methotrexate (IIIC). Follow-up time ranged from 8 months to 41 months with median of 20 months. Three of 7 patients developed subsequent CNS relapse. CNS remission durations were 8, 9, 13, 20, 28, 34, 36 months from diagnosis of CNS leukemia for which IIIC was given. Disease free survival after CNS relapse ranged from 2 to 36 months with median of 11 months. Overall survival after CNS relapse ranged from 8 to 41 months with median of 28 months. Five patients died of sepsis and bleeding secondary to bone marrow relapse. Two patients are alive at present. But they developed recurrent CNS disease 10 to 11 months after completion of IIIC. To improve the outcome, modification of IIIC by reduction of rest period and prolonged administration of intrathecal chemotherapy after completion of IIIC are required.

  • Soil erosion has been emphasized as serious environmental problem affecting water quality in the receiving waterbodies. Recently, Best Management Practices (BMPs) have been applied at a field to reduce soil erosion and its effectiveness in soil erosion reduction has been monitored with various methods. Although monitoring at fields/watershed outlets would be accurate way for these ends, it is not possible at some fields/watersheds due to various limitations in direct monitoring. Thus modeling has been suggested as an alternative way to evaluate effects of the BMPs. Most models, which have been used in evaluating hydrology and water quality at a watershed, could not reflect rainfall intensity in runoff generation and soil erosion processes. In addition, source codes of these models are not always public for modification/enhancement. Thus, runoff-sediment evaluation system using hourly rainfall data and vegetated filter strip (VFS) evaluation module at field level were developed using open source MapWindow GIS component in this study. This evaluation system was applied to Bangdongri, Chuncheonsi to evaluate its prediction ability and VFS module in this study. The NSE and $R^2$ values for runoff estimation were 0.86 and 0.91, respectively, and measured and simulated sediment yield were 15.2 kg and 16.5 kg indicating this system, developed in this study, can be used to simulate runoff and sediment yield with acceptable accuracies. Nine VFS scenarios were evaluated for effectiveness of soil erosion reduction. Reduction efficiency of the VFS was high when sediment inflow was small. As shown in this study, this evaluation system can be used for evaluation BMPs with local rainfall intensity and variations considered with ease-of-use GIS interface.
