  • This study was conducted to investigate the effects of upper thoracic joint mobilization technique using Kaltenborn-Evjenth concept on the range of cervical and thoracic motion and pain in patients with chronic neck pain. The subjects were divided into a thoracic joint mobilization group(n=7) and a conservative physical therapy group(n=7). Each of the groups received thoracic joint mobilization or conservative physical therapy three times a week lasted for four weeks. The measurements were performed for the range of thoracic segmental motion(SpinalMouse), the pain(visual analogue scale) and the range of cervical joint motion(Inclinometer, Dualer IQ). They were made four times: before experiment, at 2weeks, 4weeks, and 4weeks after experiment.

  • To understand the responses of grapevines in response to cold stress causing the limited growth and development, differentially expressed genes (DEGs) were screened through transcriptome analysis of shoots from 2 grapevine cultivars ('Campbell Early' and 'Muscat Baily A') kept at -$2^{\circ}C$ for 4 days. In gene ontology analysis of DEGs from 'Campbell Early', there were 17,424 clones related with biological process, 28,954 with cellular component, and 6,972 with molecular function genes in response to freezing temperature. The major induced genes included dehydrin xero 1, K-box region and MADS-box transcription factor family protein, and MYB domain protein 36, and inhibited genes included light-harvesting chlorophyll B-binding protein 3, FASCICLIN-like arabinoogalactan 9, and pectin methylesterase 61 in 'Campbell Early' grapevines. In gene ontology analysis of DEGs from 'Muscat Baily A', there were 1,157 clones related with biological process, 1,350 with cellular component, and 431 with molecular function gene. The major induced genes of 'Muscat Baily A' included NB-ARC domain-containing disease resistance protein, fatty acid hydrozylase superfamily, and isopentenyltransferase 3, and inhibited genes included binding, IAP-like protein 1, and pentatricopeptide repeat superfamily protein. All major DEGs were shown to be expressed differentially by freezing temperature in real time-PCR analysis. Protein domain analysis using InterPro Scan revealed that ubiquitin-protein ligase was redundant in both tested grapevines. Transcriptome profile of shoots exposed to cold can provide new insights into the molecular basis of tolerance to low-temperature in grapevines, and can be used as resources for development new grapevines tolerant to coldness.

  • To produce transgenic cucumber expressing Nit gene coffering abiotic resistance, the cotyledonary-node explants of cucumber (cv. Eunsung) were inoculated with A. tumefaciens transformed with pPZP211 or pCAMBIA2300 carrying Nit gene, that has cis-acting element involved in resistance to various abiotic environmental stresses. After co-cultivation, the procedures of selection, shoot initiation, shoot elongation, and plant regeneration were followed by cotyledonary-node transformation method (CTM, Jang et al. 2011). The putative transgenic plants were selected when shoots were grown to a length greater than 3 cm from the cotyledonary-node explants on selection medium supplemented with 100 mg/L paromomycin as a selectable agent. The confirmation of transgenic cucumber was based on the genomic PCR, Southern blot analysis, RT-PCR, and Northern blot analysis. A 105 shoots (4.12%) selected from the selection mediums were obtained from 2,547 explants inoculated. Of them, putative transgenic plants were only confirmed with 45 plants (1.77%) by genomic PCR analysis. Transgenic plants showed that the Nit genes integrated into each genome of 39 plants (1.53%) by Southern blot analysis, and the expression of gene integrated into cucumber genome was only confirmed at 6 plants (0.24%) by RT-PCR and Northern blot analysis. These results lead us to speculate that the genes were successfully integrated and expressed in each genome of transgenic cucumber.

  • Rice is one of the most important cereal crops as a model plant for functional genomics of monocotyledons and usually transformed using Agrobacterium tumefaciens. However, the transformation's process using previous method is still time consuming and uneconomical, low efficiency. In this study, we established a new method by modifying the general Agrobacterium protocol especially in the infection and co-cultivation, Agrobacterium elimination, infected calli's selection steps using liquid media. We directly inoculated Agrobacterium containing a ZjLsL gene under the control of constitutive promoter into the 1- to 3-week-old rice calli derived from mature seeds. After 3 days of co-cultivation, the infected calli were transferred onto liquid media of Agrobacterium elimination and calli's selection for 3 days. The calli were transferred to calli's growth solid media for 14 days and then the calli transferred to shoot induction and root induction media. Putative transformants were initially selected on the medium containing phosphinothricin, and the PAT protein verified by PAT strip test. This method in this study would lead to reduction of substantial labor and time to generate transgenic plants.

  • This study was conducted to investigate the influences of the rope and the tipping chute restraints on body temperature (BT) and heart rate (HR) as acute response for stress caused by restraining for diagnasis and treatment in cattle. Both parameters were recorded by active biotelemetry. In addition cortisol concentration in blood was analyzed as a indicator for stress response. Twelve cattle were divided into two groups based on hydraulic power, the rope restraint group and the tipping chute restraint group. BT and HR were measured at -30 (base), 0, 10, 20, 30, 40, 50, 60, 90, 120, and 180 minutes, including restraint period from 0 to 30 minutes during the experiment. The results obtained in this study was summarized as follows: 1. BT of the rope restraint group was increased ($39.8{\pm}0.3^{\circ}C$) until 20 min after restraint stress for 30 min, and then maintained with high values to the end of experiment. In the tipping chute restraint group, the BT was increased ($39.6{\pm}0.3^{\circ}C$) until the end of the restraint period, but then showed decrese until the end of experiment. 2. HR of both groups was maximized at the beginning of the restraint stress (P<0.05), and then it was decreased gradually but in the tipping chute restraint group showed increase again at the end of the reatraint stress (P<0.05). 3. The cortisol level of the rope restraint group was increased significantly ($9.72{\pm}5.09{\mu}g/d{\ell}$) until 30 min after the end of the restraint stress (P<0.05) and then decreased, but in the tipping chute restraint group showed great increase ($4.68{\pm}1.56{\mu}g/d{\ell}$) at the end of the restraint stress (P<0.05) and then decreased while the tipping chute restraint group was significantly lower than the rope restraint group 30 min after the restraint stress (P<0.05). In conclusion, this study suggests that the tipping chute restraint produces less response to physical stress than the rope restraint but the time for diagnasis and treatment should be shortened when using the tipping chute restraint.

  • Whole genome transcriptomes from Miscanthus species were sequenced and analyzed, which provided 50 different types of transcription factor (TF) involving various developmental processes or environmental stresses. Among the explored TF, WRKY gene family was the major type and one of the WRKY genes, MSIR7180_WRKY4, induced under low temperature environment was selected to investigate how the Miscanthus-originated MSIR7180_WRKY4 TF responds when exposed to low temperature in four warm-season turfgrasses (Z. matrella 'Semil', bermudagrass, St. Augustinegrass, and seashore paspalum). The MSIR7180_WRKY4 was expressed higher during low temperature period in Bermudagrass, but the expression was enhanced in St. Augustinegrass. In contrast, the gene in 'Semil' cultivar was barely expressed and relatively less expressed, but repressed gradually in seashore paspalum, which seems to allow two turfgrasses stay-green longer in the fall season. The results indicate that bermudagrass and St. Augustinegrass adapt to low temperature quickly, but relative tolerance to low or cold temperature at the molecular level needs to be further investigated at different physiological stages and the corresponding genes systematically.

  • Congenital aortic stenosis in children is characterized by "excessive" left ventricular hypertrophy with reduced left ventricular systolic wall stress that allows for supernormal ejection performance. We hypothesized that left ventricular wall stress was decreased immediately after surgical correction of pure congenital aortic stenosis. Also measuring postoperative left ventricular wall stress was a useful noninvasive measurement that allowed direct assessment for oxygen consumption of myocardium than measuring the peak systolic pressure gradient between ascending aorta and left ventricle for the assessment of surgical results. Material and Method: Between September 1993 and August 1999, 8 patients with isolated congenital aortic stenosis who underwent surgical correction at Yonsei cardiovascular center were evaluated. There were 6 male and 2 female patients ranging in age from 2 to 11 years(mean age, 10 years). Combined Hemodynamic-Ultrasonic method was used for studying left ventricular wall stress. We compared the wall stress peak systolic pressure gradient and ejection fraction preoperatively and postoperatively. Result: After surgical correction peak aortic gradient fell from 58.4${\pm}$17.6, to 23.7${\pm}$17.7 mmHg(p=0.018) and left ventricular ejection fraction decreased but it is not statistically significant. In the consideration of some factors that influence left ventricular end-systolic wall stress excluding one patient who underwent reoperation for restenosis of left ventricular outflow tract left ventricular end-systolic pressure and left ventricular end-systolic dimension were fell from 170.6${\pm}$24.3 to 143.7${\pm}$27.1 mmHg and from 1.78${\pm}$0.4 to 1.76${\pm}$0.4 cm respectively and left ventricular posterior wall thickness was increased from 1.10${\pm}$0.2, to 1.27${\pm}$0.3cm but it was not statistically singificant whereas left ventricular end-systolic wall stress fell from 79.2${\pm}$24.9 to 57.1${\pm}$27.6 kdynes/cm2(p=0.018) in 7 patients. For one patient who underwent reoperation peak aortic gradient fell from 83.0 to 59.7 mmHg whereas left ventricular end-systolic wall stress increased from 67.2 to 97.0 kdynes/cm2 The intervals did not change significnatly. Conclusion ; We believe that probably some factors that are related to left ventricular geometry influenced the decreased left ventricular wall stress immediately after surgical correction of isolated congenital aortic stenosis. Left ventricular wall stress is a noninvasive measurement and can allow for more direct assesment than measuring peak aortic gradient particularly in consideration of the stress and oxygen consumption of the myocardium therefore we can conclude it is a useful measurement for postoperative assessment of congenital aortic stenosis.

  • Effluent of aquaculture industry has caused a growing concern regarding its environmental impact. We assessed the use of flounder farming sewage as supplement of diet, to minimize the impact of aquaculture on the environment or also establish the technique for the recycling of effluent sediment derived from land-based seawater fish farm. In order to investigate the effects of a fermented aquaculture waste on biochemical responses of olive flounder (Paralichthys olivaceus), fermented products of aquaculture wastes were used as test compounds that cause hepatic and renal stress through the induction of oxidative stress in liver and kidney. Hepatosomatic index (HSI), glutathione content and glutathione dependent enzyme were not significantly different and no correlation was found within the different types of fermentation condition or supplement concentration, except for significant increases in 50% fermentation group and 50% concentration group in case of glutathione peroxidase activity and HSI value, respectively. These results showed addition of fermented aquaculture sewage may be an economic artificial sources of diet for fish aquaculture practices without affecting the function and safety in view of biochemical examination.

  • The main premise of this study is that a successful treatment and rehabilitation of the mentally ill depends on an active. coping of their family members, who are the primary care-takers of the patients, even if families are confronting many difficulties because of caring their patients. Accordingly, this study aims to find out which factors are related to families active coping with the mentally ill. This study is conducted the survey with 191 family members of the mentally ills in order to discover: 1) what kinds of relations do exist between sociodemographic factors of the respondents, care-burden toward the mentally ill, and social supports, and the active coping, and 2) in what extent do these related factors affect on the active coping. The major findings of the study are: 1) gender and educational background of the respondents are positively related to the active coping; 2) regarding care-burden felt by the respondents, there is statistically significant positive relationship between - the respondents' burden due to a lack of social and institutional support and their active coping; 3) considering the relationship with social support, there is highly positive relationship between decision. emotional. material supports and the active coping; 4) using a multiple regression, respondents' sociodemographic background, care-burden, social support affect significantly on the active coping by 26.2% of explanatory power; and 5) using a step-wise multiple regression, the most powerful influenced factors on active coping are emotional support, burden due to a lack of social and institutional support, and educational background of the respondents. In conclusion, this study recommends clinicians to use an educational and support model for the families. All these efforts will contribute to enhance active coping of the families with the mentally ill.

  • This qualitative study is designed for the reconstruction of the experience of single mothers in poverty based on the bottom-up approach. Welfare dependency is identified as vital help to protect their own and children's lives, through their stories telling that welfare services provided by government and community take care of them "in place of their husbands", and "raise them up by hand." What is self-sufficiency to them is more of a process-orientation through welfare dependency than a state out of it, and a way to look through building their self-esteem and working to discover their self-worth except their economic power. Restoring their potential to self-sufficiency through dealing with their psycho-social stresses and expanding services for them related to child-care(education) and occupation ability development for long-term self-sufficiency, rather than hasty focusing on welfare exit, should be built on the foundation of helping them self-sufficient. In order for the self-sufficiency program to overcome the participant's images of "subordination and stigma" and to convey the original meaning of "welfare to work", the performance and evaluation system of self-sufficiency programs that reflects the insider's perspectives on their participation motive and process, and the self-sufficiency program customized for their needs and interests should be encouraged to develop.
