This study was from the survey on the items related to the challenges, the activity frequency of the challenged people and the places where these activities take place and the satisfaction and the demands on the facilities for the challenged people from 1,284 challenged people over the age of 20 living in Korea nation wide. From the survey, it was shown that the biggest demand lied in the improvement of the facilities related to the transportation and access for their residence and social activities. They felt they are inconvenient for the perspective of the implementation rate. Additionally, they had high desire for culture and physical educational activities. Improvements to provide convenient environments where the challenged people can access to and use the facilities as conveniently as unchallenged people do by minimizing the physical hindrances are urgently needed. For time being, many facilities for the challenged people was supplied to improve the physical environments for challenged people, however, foreign regulations had to be adopted for these job due to insufficient date on physical conditions of the challenged people in Korea. Moreover, current facilities for the challenged people emphasized more on physical aspect and the facility itself without the considerations on the overall environments, as result the improvement satisfaction and efficiency were low. More flexible and humane design approaches are needed instead of relying on supply rate and try to fully consider the characteristics of the challenged people without any discrimination.

The purpose of this paper is to study and propose playground facilities for physically challenged children to cultivate adaptability in society and advances the opportunity of participate in physical exercise. This study carried out site investigations by visiting and inspecting various facilities: a recreational walking path for physically challenged people, a care facility for physically challenged children, a special school for physically challenged children, and "Madel Park", a private-use playground for physically challenged children. The result of the site investigation found that, overall, play facilities are difficult to use for physically challenged children. In addition, because park space is often small and narrow, children who are restricted to wheelchairs find it impossible to access such facilities. By carefully inspecting each of the facilities, the author found suitable elements to apply for outside play space. These elements include the introduction of an essential slope way to allow for safe movement, the provision of special seats which support the body to outside play equipment and the adaptation of treatment room instruments that assist balance to outdoor playground facilities. On the basis of the site investigation the interview and the indoor education program for physically challenged children the author completed an outside play program. Each item in this program was classified as belonging to either a "sense play" program or and "exercise play" program. Finally, the author designed suitable play equipment for physically challenged children corresponding to each item in the exercise programs in order to research the appropriateness of the equipment to its intended use. This research is the first step. From this point the author expects that specific applications will be developed through a practical space plan and sufficient clinical experiments involving use of the new equipment.

SIRT5 and PRDx1 play crucial roles in cancer and are involved in the basic mechanisms of reactive oxygen species detoxification. In our previous studies, we showed that hemolymph extracts of immune-challenged Bombyx mori have antioxidant properties. Following H2O2 stimulation, immune-challenged B. mori hemolymph extracts elicited SIRT5 downregulation activity, reaching effective activity at the highest concentration of 100 ppm. Additionally, cells treated with immune-challenged B. mori hemolymph extracts demonstrated increased PRDx1 mRNA expression compared to that of PBS-treated cells. Therefore, immune-challenged B. mori hemolymph extracts offer a potential auxiliary means of treating drug-resistant tumors through downregulation of SIRT5 and upregulation of PRDx1 expression. Nevertheless, further studies on the effects of B. mori hemolymph on SIRT5 and PRDx1 regulation are pertinent for using it as a food or pharmaceutical material and understanding its therapeutic effect on tumors, including those that are drug-resistant.

Background: Porcine circovirus type 2 (PCV2) and Mycoplasma hyopneumoniae (MHP) are economically significant pathogens in the pig industry. The use of combined vaccines against PCV2 and MHP is one of the most effective ways of protecting pigs from both diseases, and it has become a part of general management. Objectives: This study evaluated the efficacy of two new bivalent vaccines of PCV2 and MHP (Myco-X and Myco-XD) in SPF pigs. Myco-X and Myco-XD are a combined vaccine of MHP with PCV2b and PCV2d, respectively. Methods: Sixteen pigs were divided into four groups: Myco-X-vaccinated challenged, Myco-XD-vaccinated challenged, unvaccinated challenged, and unvaccinated unchallenged. Two milliliters of Myco-X were administered intramuscularly, and 0.5 mL of Myco-XD was injected intradermally at 3 wk of age. The pigs were challenged with virulent PCV2d via the intramuscular and intranasal route 4 wk post-vaccination. Results: All vaccinated pigs showed effective reduction of the clinical signs, the PCV2d load in the blood and nasal swab samples, as well as lung and lymphoid tissue lesions in the challenge test. Compared to unvaccinated challenged animals, the vaccinated challenged animals showed significantly higher (p < 0.05) levels of anti-PCV2 IgG, PCV2d-specific interferon-γ (IFN-γ), and anti-MHP IgG. Conclusions: Based on clinical, microbiological, serological, and pathological assessments, this study confirmed that both combined vaccines could protect pigs against PCV2 infection caused by PCV2d. On the other hand, further research on the efficacy evaluation of these new vaccines against the MHP challenge and PCV2d/MHP co-challenge is needed.
Purpose - This study is intended to explore influential factors on the life satisfaction of physically challenged laborers preparing for support plans for their future. This is to enjoy a better life and have social opportunities and to review institutional support or plans for implementation to be applied for physically challenged people. Research design, data, and methodology - 4,161 disabled people participated in the Panel Survey of Employment of the Disabled. Among 2,124 physically challenged people, 957 wage workers (45%) were primarily extracted in this study, and a total of 581 (27%) with sufficient responses on the questionnaires were finally selected. Results - First, physical preparation for later life had a positive influence on retired life satisfaction among retirement satisfaction. People showed higher retired life satisfaction. Secondly, physical preparation for later life had a positive influence on satisfaction over relationship after retirement among retirement satisfaction. Conclusions - In this study, it was found that job satisfaction was the variable with the highest influential power on life satisfaction. Therefore, it seems to be necessary to proceed a research as to which factors influence life satisfaction in the medium of job satisfaction and also about plans to improve job satisfaction on experts or the disabled.
A human being's pursuit is that of a better quality of life and the disabled naturally want to do so. But challenged people's lives have not improved apace with the general development of our society as a whole. Specially, in a patriarchal society like Korea, challenged women are in a less favorable situation. Challenged women can enjoy more healthy and more happy life in a given condition. Thus, in this research, we closely examined the women's general characteristics, disabled characteristics, health condition(subjective health condition, experiences of diseases, stress value, etc), satisfaction value of life who have handicaps of limb or/and body. On the 17th of September through the 14th of October '98, a nation-wide retardation compaign was held and 200 people were served by telephone. Then we analysed primary factors on quality of life. As results, monthly income, how they think of their economic level, their subjective health condition, and the stress level that the success depends on self influenced quality of life.

In a search for new molecular pathways associated with asthma, we performed an mRNA differential display analysis using total RNA extracted from the tracheal tissues of ovalbumin (OVA)-challenged mice and sham controls. cDNAs corresponding to mRNAs for which expression levels were altered by OVA-challenge were isolate and sequenced. Twenty-eight genes differentially expressed in sham and OVA challenged mice were identified. A GenBank BLAST homology search revealed that they were related to cytoskeleton remodeling, transcription, protein synthesis and modification, energy production, and cell growth and differentiation. Two were selected for further characterization. Up-regulation of both the perinatal skeletal myosin heavy chain (skMHC) and fast skeletal muscle myosin light chain (skMLC) genes was confirmed by RT-PCR of trachea tissue from OVA challenged mice. Overexpression of skMLC protein was observed in the smooth muscle layers of OVA-challenged mice by immunohistochemistry, and the surface areas stained with skMLC antibody increased in the OVA-challenged mice. The overexpression of skMLC in murine asthma may be associated with the changes of bronchial smooth muscle.

The immune response against Salmonella gallinarum infection was investigated in immunosuppresed chickens. Newly hatched chickens were treated with cyclophosphamide at the first and second day after birth and were challenged intraperitoneally with S gallinarum ($1{\times}10^7CFU/m{\ell}$) on day 6. Group 1, Immunosuppresed and Challenged group, was treated with cyclophaiphamide and challenged with S gallinarum; group 2, Immunosuppressed group, was only treated with cyclophsphamide; group 3, Challenged group, was only challenged with S gallinarum; group 4, Control group. In each group, the localization of lymphocytes of the lymphoid organs and intestine was immunohistochemically compared using a variety of monoclonal antiboies ($CD4^+$, $CD8^+$, and B lymphocyte). Also, S gallinarum were assessed by Maccallum-Goodpasture stain and immunohistochemical analysis in the paraffin-embedded intestinal tissues. In S gallinarum challenged chickens, $CD4^+$ and $CD8^+$ lymphocytes of the intestinal organs such as duodenum, jejunum, ileum and colon were increased. However, in cyclophophamide treated chickens, $CD4^+$ and $CD8^+$ lymphocytes and especially B lymphocytes of the lymphoid organs such as thymus, spleen, and bursa of Fabricius were dramatically decreased. These results suggest that cyclophsophamide is an immunosuppressive agent that especially causes depletion of B lymphocytes, suppress humoral immunity and eventually suppresses avian immune responses. Its protection against S gallinarum infection is mainly dependent on both cell-mediated mechanism and the humoral immune response.

This study was conducted to evaluate the efficacy of a combination 3,4,5-trihydroxybenzoic acid (THB) and oregano extracts (i.e., Carvacrol and Thymol) at intake/dietary different levels on growth performance, intestinal health indicators, immune responses and fecal oocyst shedding in broiler chickens under Eimeria challenged condition. A total of 336 one-day-old broilers were randomly assigned to one of six dietary treatments with seven replications per treatment. Dietary treatments were: i) Non-challenged bird without any dietary treatment (NCNT), ii) Challenged bird without any dietary treatment (CNT), iii) Challenged birds fed a THB diet (0.1 g/kg, THB), iv) Challenged birds fed a combination of THB and oregano extracts diet (0.1 g/kg, COM 100), and a gradual increase of combination of THB and oregano extracts likely v) 0.15 g/kg (COM 150), and 0.2 g/kg (COM 200). On day 14, all groups except for NCNT have orally challenged with a 10-fold dose of Livacox® T anticoccidial vaccine to trigger coccidiosis. The results indicated that Eimeria-challenged broilers fed COM 100 and COM 200 diets increased (p < 0.05) body weight than CNT diet on day 35. Furthermore, birds fed COM 100 and COM 200 diets increased (p < 0.05) average daily gain compared to those fed CNT diets for the entire experimental period. There is no significant (p > 0.05) in average daily feed intake, feed efficiency between NCNT and birds fed with combined THB and oregano extracts for the entire experimental period. A combination of THB and oregano extract regardless of concentration levels or THB alone reduced (p < 0.05) lesion score in ileum compared to the CNT diet for 7 days post-infection (dpi). Birds fed COM 100 diet had lower (p < 0.05) intestinal lesion scores in jejunum and caeca on 7 dpi compared to those were in the CNT diet. No (p > 0.05) difference was observed in the oocysts per gram of feces count, intestinal morphology, carcass traits and blood cytokine concentration among the infected treatments. Collectively, we conclude that birds fed with a combination of THB and oregano extracts regardless of the ratios that were used demonstrated better recovery of health after the coccidial challenge than using only THB alone.
This study was conducted to evaluate the effects of dietary supplementation of plant flavonoid (quercetin) on immune parameters, growth performance, and nutrient digestibility in growing pigs challenged with Escherichia coli lipopolysaccharide (LPS). A total of 40 crossbred ([Landrace × Yorkshire] × Duroc) growing pigs; initial body weight (BW) of 26.95 ± 1.26 kg were used in a six-week experimental trial. Pigs were randomly allocated into one of four treatment groups in a 2 × 2 factorial arrangement with the following factors; without LPS challenge and with LPS challenge (day 21) supplemented with or without 0.1% flavonoid according to BW (2 replicate pens per treatment with 2 gilts and 3 barrows per pen). The single-dose LPS (100 ug / kg BW) injection showed trends tended to be increased in interleukin-6 (IL-6) after 2 h and 6 h of challenge compared with unchallenged pigs. However, other measured immune indices (white blood cell, immunoglobulin G, lymphocyte, and tumor necrosis factor), growth performance, and nutrient digestibility were not significantly different between challenged and non-challenged animals. The supplementation of flavonoid significantly increased (p < 0.05) average daily gain (ADG) during day 0-21, tended to increase dry matter and nitrogen digestibility, significantly reduced IL-6, increased Ig-G and WBC concentrations and increased lymphocytes percentage regardless of LPS challenge.
