  • Two experiments were conducted to examine the effects of dietary inclusion of xylose on growth performance, nutrient digestibility and xylose absorption in the portal-drained viscera of broiler chicks. In Exp. 1, ninety male 14 day-old broilers were used to study the effects of different inclusion levels (0, 5, 10, 20 and 40%) of D-xylose in the semi-purified diets on the growth and nutrient digestibility of broilers. In Exp. 2, One hundred and eight male broilers, fed by precision feeding at 22 day-old, were used to investigate the absorption and transportation of dietary xylose in the portal-drained viscera of broiler. The results of Exp. 1 indicated that the growth of broilers was gradually decreased as the xylose level increased (p<0.01). With the xylose supplementation increased, the moisture in broiler excreta was gradually elevated (p<0.01), AME and the digestibilities of crude protein and ether extract were significantly reduced and the digestibilities of xylose and arabinose were also decreased (p<0.01). The results of Exp. 2 showed that the concentrations of ribose, xylose and galactose in serum were significantly influenced by different dietary levels of xylose (p<0.01), but there's no apparent difference among rhamnose, glucose and arabinose (p>0.05). The xylose concentration in serum was highest in Vena Cava, middle in Portal Vein and lowest in Ulnar Vein within 6 h after precision feeding. And then the xylose concentration in Portal Vein and Ulnar Vein were higher than that of Vena Cava. The concentration of ribose, xylose and galactose in serum were also significantly changed with time prolongation (p<0.01). The concentration of xylose in serum was highest in the 40% xylose treatment, middle in the 20% xylose group and lowest in the control group. The glycogen contents in liver and muscle were linearly decreased as the level of xylose increased (p<0.01). The higher the dietary level of xylose was, the lower digestibility of dietary xylose was (p<0.10). 40% xylose markedly decreased the digestibility of dietary glucose (p<0.01). In conclusion, high levels of xylose in the diets inhibited the growth and nutrient digestibility of broiler. The outputs of xylose from the hydrolyzation of wheat-based diet by xylanase should have no adverse effects on broiler performance.

  • Objective: This experiment was conducted as a $3{\times}2{\times}2$ factorial design to examine the effects of particle size (mean particle size of 331, 640, or $862{\mu}m$), evaluation method (direct vs indirect method) and adaptation duration (7 or 26 days) on the energy content and the apparent total tract digestibility (ATTD) of various chemical components in wheat when fed to finishing pigs. Methods: Forty-two barrows ($Duroc{\times}Landrace{\times}Yorkshire$) with an initial body weight of $63.0{\pm}0.8kg$ were individually placed in metabolic cages and randomly allotted to 1 of 7 diets with 6 pigs fed each diet. For the indirect method, the pigs were fed either a corn-soybean meal based basal diet or diets in which 38.94% of the basal diet was substituted by wheat of the different particle sizes. In the direct method, the diets contained 97.34% wheat with the different particle sizes. For both the direct and indirect methods, the pigs were adapted to their diets for either 7 or 26 days. Results: A reduction in particle size linearly increased the digestible energy (DE) and metabolizable energy (ME) contents as well as the ATTD of gross energy, crude protein, organic matter, ether extract (EE) and acid detergent fiber (ADF) (p<0.05), and had a trend to increase the ATTD of dry matter of wheat (p = 0.084). The DE, ME contents, and ATTD of gross energy, crude protein, dry matter and organic matter were higher (p<0.05) when determined by the direct method, but the ATTD of ADF, EE, and neutral detergent fiber were higher when determined by the indirect method (p<0.05). Prolongation of the adaption duration decreased the ATTD of neutral detergent fiber (p<0.05) and had a trend to increase the ATTD of EE (p = 0.061). There were no interactions between particle size and the duration of the adaptation duration. The ATTD of EE in wheat was influenced by a trend of interaction between method and adaptation duration (p = 0.074). The ATTD of ADF and EE in wheat was influenced by an interaction between evaluation method and wheat particle size such that there were linear equations (p<0.01) about ATTD of ADF and EE when determined by the direct method but quadratic equations (p = 0.073 and p = 0.088, respectively) about ATTD of ADF and EE when determined by the indirect method. Conclusion: Decreasing particle size can improve the DE and ME contents of wheat; both of the direct and indirect methods of evaluation are suitable for evaluating the DE and ME contents of wheat with different particle sizes; and an adaptation duration of 7 d is sufficient to evaluate DE and ME contents of wheat in finishing pigs.

  • Background: XELOX plus bevacizumab (XELOX-Bev) and FOLFIRI plus Bevacizumab (FOLFIRI - Bev) treatments are an effective strategies patients with metastatic colorectal cancer (mCRC).The aim of this study was to compare efficacy of first-line XELOX-Bev treatment vs FOLFIRI-Bev treatment for mCRC. Materials and Methods: A total of 409 patients with mCRC who received chemotherapy were included and divided into 2 groups. Group 1 (n=298) received XELOX-Bev and Group 2 (n=111) FOLFIRI-Bev. Comparisons were made in terms of overall (OS) and progression-free (PFS) survival, response rate (RR), and grade 3-4 toxicity. Results: Median follow-up was 11 months in Group 1 and 15 months for Group 2. Complete remission was observed in 29 (9.7%) and 2 (1.8%) patients, partial remission in 139 (46.6%) and 27 (24.5%), stable disease in 88 (29.5%) and 49 (44.1%) and progressive disease in 42 (14.1%) and 33 (30.0%) patients in Group 1 and 2, respectively. Median OS was 25 months (range 2-57 months, 95%CI; 22.2-27.7) for Group 1 and 20 months (range 1-67 months, 95%CI; 16.8-23.1) for Group 2 (p=0.036). Median PFS was 9.6 months (range 2-36 months, 95%CI; 8.8-10.4) for Group 1 and 9 months (range 1-44 months, 95%CI; 7.4-10.5) for Group 2 (p=0.019). Objective RR was 56.4% in Group 1 and 26.1% in Group 2 (p<0.001). Conclusions: First-line XELOX-Bev is more effective with a better response rate, prolongation of median PFS/OS, and a superior safety profile compared with FOLFIRI-Bev.

  • Recently, due to the global economic crisis and prolongation of slow growth period, many countries have proposed creative economy as an important policy for economic growth. Korea has also progressed important policies such as development of creative industries, start-up activation and employment creation through creative economy as a key policy. However, each country has a different definition of creative economy and detailed field to promote, and there is a lack of research on creative economy of industrial complexes and activation plans of creative industries. This study derived the priority order and importance of development plans to develop into creative clusters through AHP analysis base on Gumi National Industrial Complex that have had a significant role in the national economy since the 1970s. As a result, the creativity enhancing factor was the highest priority, followed by creative infrastructure and network. These results mean that it is necessary to promote creativity in order national industrial complexes to continuously lead national economy and for this purpose it needs to prioritize the development of creative human resources and to extend the creative R&D. This study can be provided to government and local policy makers and innovation agencies as basis data and practical policy guide to establish a successful creative cluster by deriving the priority order in reflection of both hardware and software policies such as infrastructure to develop national industrial complex into creative cluster.

  • Yoga meditation and music therapy are considered to be appropriate for the spiritual and mental treatment for the patients and employed in many clinics and rehabilitation centers as an alternative medicine. This study aims at the analysis of the effects of yoga and music on the treatment of alcoholism. For this, yoga and music treatments were executed for the patients hospitalized in an alcohol clinic hospital in Gimhae district. Only the patients who were judged as alcohol dependents by a psychiatrist with a diagnostic criteria of DSM-IV participated in the study. During five weeks, from November 10, 2009 to December 29, yoga program was practiced two times per week, totaling 10 times, and music therapy was practiced one time per week, totaling 5 times. Among the patients participated in the programs, 44patients were selected finally. They are 16 patients who performed all the yoga programs, and 28 patients who fulfilled all the music therapies. A survey was conducted on them to estimate the effects of yoga and music treatments for the three cases of 'angry behavior', 'anger expression', and 'psychological state at interview'. The results show that yoga and music treatments have positive effects on the patients, although the statistical significance is not so great. However, the more reliable and significant results could be obtained in further studies by prolongation of the practice period, and by introducing the clinical information such as brain mapping to compensate the emotional bias of the patients.

  • Pleurotus nebrodensis is an edible and commercially available mushroom in Korea. This study was conducted in order to evaluate the anticancer and immunopotentiating activities of crude polysaccharides, extracted in methanol, neutral saline, and hot water (hereafter referred to as Fr. MeOH, Fr. NaCl, and Fr. HW, respectively) from the fruiting bodies of P. nebrodensis. ${\beta}$-Glucan and protein contents in Fr. MeOH, Fr. NaCl, and Fr. HW extracts of P. nebrodensis ranged from 23.79~36.63 g/100 g and 4.45~6.12 g/100 g, respectively. Crude polysaccharides were not cytotoxic against sarcoma 180, HT-29, NIH3T3, and RAW 264.7 cell lines at a range of $10{\sim}2,000{\mu}g/mL$. Intraperitoneal injection with crude polysaccharides resulted in a life prolongation effect of 11.76~27.06% in mice previously inoculated with sarcoma 180. Treatment with Fr. NaCl resulted in an increase in the numbers of spleen cells by 1.49 fold at the concentration of $50{\mu}g/mL$, compared with control. Fr. HW improved the immuno-potentiating activity of B lymphocytes through an increase in alkaline phosphatase activity by 1.65 fold, compared with control at $200{\mu}g/mL$. Maximum production of nitric oxide ($14.3{\mu}M$) was recorded in the Fr. NaCl fraction at $200{\mu}g/mL$. Production of tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interleukin-$1{\beta}$ (IL-$1{\beta}$), and interleukin-6 (IL-6) was significantly higher, compared to control, and IL-6 production was highest, in contrast to TNF-${\alpha}$, IL-$1{\beta}$, and positive control, concanavalin at the tested concentration of the various fractions. Results of the current study suggest that polysaccharides extracted from P. nebrodensis have a strong anticancer effect and may be useful as an ingredient of biopharmaceutical products for treatment of cancer.

  • The Gilan-Cheongsong area, which is in contact with Yeongyang and Uiseong Blocks of Gyeongsang Basin, Korea, consists of Precambrian metamorphic rocks, Triassic Cheongsong granite, Cretaceous sedimentary rocks(Iljik, Hupyeongdong, Jeomgok Formations), and Cretaceous igneous rocks(andesite, quartz porphyry, felsite). In this area are developed faults trending in (W)NW, NNW, ENE, NS, (N)NE directions which are representative in the Gyeongsang Basin. We analyzed the geometric and kinematic characteristics of fracture systems to inquire into movement history and sense of these faults in this area. This study suggests that these faults were mainly strike-slip movement. The orientations of fracture sets show ENE, NNW, (W)NW, (N)NE, NS in descending order of frequency. Their prolongation presents (W)NW, NNW, ENE, (N)NE, NS in descending order of predominance, and also agrees with that of faults in this area. The development sequence and movement sense of fracture sets are summarized as follows; (1) (W)NW: dextral shearing $\rightarrow$ (2) (W)NW and NNW: conjugate shearing(the former: dextral, the latter: sinistral) $\rightarrow$ (3) NNW: dextral shearing $\rightarrow$ (4) (W)NW: sinistral shearing $\rightarrow$ (5) ENE: dextral shearing $\rightarrow$ (6) ENE and NS: conjugate shearing(the former: sinistral, the latter: dextral) $\rightarrow$ (7) (N)NE: sinistral shearing, and this result is closely associated with the development sequence and movement sense of faults developed in this area.

  • Whole and stem-off cherry tomatoes were packaged using perforated films(LF05, LF10, LF20, and LF40). Gas composition(ethylene, $O_2$, and $CO_2$), firmness(compression and penetration force), color, brix degree, acidity, and total microbial counts were assessed during storage at $10^{\circ}C$ and 85% relative humidity. Gas composition varied with film gas permeability, indicating that modified atmospheric(MA) conditions were achieved. Firmness fell during storage; samples packed using LF05 showed the lowest firmness, corresponding to low gas transmission conditions. L(lightness) and a(redness) values respectively decreased and rose slightly with increasing storage time, but the b(yellowness) values fell notably. Film permeability significantly affected acidity and soluble solid levels. When LF40 packaging was used, acidity and brix scale changes were similar to those seen after PET container packaging. Total microbial counts increased with time after packaging in most films, and pretreatment differences were not significant. Microflora varied between stem on/off tomatoes. Skin wrinkling and juice appearance were common in tomatoes stored in PET containers and LF films of low gas permeabilities(LF05, LF10, and LF20). White molds were partially found on stem-on tomatoes stored using packaging systems. When film packagings were compared, LF40 was optimal, permitting minimal pretreatment yet offering maximal sanitation.

  • Death and dying of human being is a comprehensive system, and death orientation, the subjective meaning related to every component of the death system is developed throughout life. This study was designed and carried out to identify, describe and classify the orientations of Korean adult towards the death system. In an attempt to measure the subjective meaning of death and dying, unstructured Q-methodology was used. The 65 Q-statements developed by Kim(1994), used by Kim(1994) and Park(1996) were adopted as Q-population and 39 Q-statements were selected by the three researchers for Q-items for this study. Thirty-three P-samples were sampled from P-population of literate Korean men and women, 35 and 55 years of age, lived in urban Korea for the last 10 years. Sortings of the 39 Q-items according to the level of personal agreement, and a forced normal distribution into the 9 levels were carried out by the P-samples. The Z-scores of the Q-sort data were computed, and the principal components factor analysis by PC-QUANL Program were carried out. The demographic, socio-cultural and health-related attributes of the P-samples were descriptively analysed. Eight types of death orientation were identified ; Type I ; 'naturalist'. Six P-samples. Death is a natural phenomena, to be accepted as it is and to follow its natural course. Prefer to be informed of all facts and possibilities concernig the course of dying and death to occur to self. Type II ; 'life-after-life negator'. Three P-samples. Time and process of death is the destiny of each person. Death means 'darkness' and 'end to every thing, the absolute end'. Yet, wish physical integrity at the dying and after death. Type III ; 'life-after-life believer'. Six P-samples. Men are travellers passing by this life bound to the life-after-life. Priority concerns are on the activities to prepare self for the eternal life ahead. Disregard premature and sudden death. Type IV ; 'here-now believer' Five P-samples. Positive regard to the cremation of the body and donation of the organs on death. Regard religious and customary post-motem rituals meaningless. Negate life-after life. Type V; 'believer of rituals'. Five P-samples. Death being accepted as a part of, a natural end to, and destiny of human life. Concerned to ensure a dignified end to personal life and dignified post-mortem rituals. Type VI ; 'Realist'(derived from Type I). Two P-samples. Life and death as universal reality. The abrupt death at golden age at the peak of happiness is favored to avoid inevitable physical and mental distress of self and the family. Agreed to the cremation of the body. Disregard rituals. Type VII : 'Fatalist' (derived from Type II). Five P-samples. Not favored, yet, all man are destined to death, the inevitable end of all living beings. To ensure dignified end by personal consummation, information on one's dying and imminent death are to be shared. Type VIII ; 'reality avoider'(derived from Type III). One P-sample. Negative to longevity, artificial prolongation of, meaningless and distressful life. Highly positive to postmortem organ donation.

  • Distinguishing aphasia in stroke patients and observing the subtle linguistic characteristics associated with it primarily requires the use of instruments that provide reliable assessment results. Additionally, examiners should be fully aware of how to use those instruments. This study examined 46 stroke patients for aphasia and assessed the reliability of their diagnoses according to examiners whose medical fields were different from each other. Furthermore, a comparison was made between the reliability before training and that after training. To this end, 46 stroke patients were tested for aphasia and in terms of their speech disorder degree by 3 groups, each of which consisted of 12 professionals (3 SLP, 3 neurologist, and 3 nurse). In the result, a rating of 'acceptable' was given for speech intelligibility tasks and the voice quality of /ah-/ prolongation, and other sub-tests were marked as 'good-excellent' by the experts with different areas of medical expertise. For the tasks marked as 'acceptable', the subjects were video-trained for 3 weeks and the differences were compared before and after their training. Consequently, the differences in the examiners' ratings in the speech intelligibility tasks showed a significant decrease and the accuracy of their voice quality ratings showed a significant increase. In the result of research on the correlation between the accuracy of the sub-test ratings and the amount of clinic experience, speech therapists developed more accuracy in rating a picture description task and a speech intelligibility task as their experience accumulated. Meanwhile, doctors and nurses showed more accurate ratings in picture description tasks with greater clinical experience. The results of this study suggest that assessing the neurologic-communicative disorders of stroke patients requires ongoing training and experience, especially for speech disorders. It was also found that the rating reliability in this case could be improved by training.
