스탠다드국화 신품종을 육성하기 위하여 충남농업기술원 화훼연구소에서 2009년에 황색의 모본 ‘Summer Yellow’와 부본 ‘ST07-09-02’계통을 인공 교배하였다. 2010년에 종자를 파종하였고, 이중 내병성이 강하고 기호성이 우수한 개체를 선발하여 ‘ST10-047-01’로 계통명을 부여하였다. 2011년부터 2013년까지 주년 생산성을 위해 촉성 및 자연, 억제재배 특성을 각각 검정하였으며, 2013년 ‘Geumhwa’로 명명하고 품종등록 출원하였다. ‘Geumhwa’의 생육 및 개화특성은 국내에서 많이 재배되고 있는 황색 스탠다드국화인 ‘Summer Yellow’를 대조 품종으로 하여 조사하였다. ‘Geumhwa’ 품종은 자연개화기가 10월 6일로 ‘Summer Yellow’의 10월 25일에 비해 빨랐다. ‘Geumhwa’는 초장이 86.3cm로 ‘Summer Yellow’의 93.8cm보다 작았고, 곁가지 제거수는 8.1개로 ‘Summer Yellow’의 16.6개보다 적었다. ‘Geumhwa’의 꽃직경은 13.6cm로 ‘Summer Yellow’의 13.5cm와 비슷하였으며, 꽃잎수는 ‘Geumhwa’가 263.6개로 ‘Summer Yellow’의 295.3개보다 적었다. 재배상 유의사항은 ‘Geumhwa’는 중간종이므로 초기생육이 왕성하도록 비배 관리를 하고 생육기간 중 지베렐린 1,000mg･L-1를 2회 처리하여 신장력을 높이도록 한다. 또한 설상화수가 적은 편이므로 재전조를 실시하여 설상화수를 늘린다면 황색의 연중 조기개화가 가능한 고품질 신품종 스탠다드 절화국화로써 소비자 기호 충족 및 농가소득 창출에 기여할 수 있을 것으로 기대된다.

This study aims to identify the effect of home physical therapy on patients who left the hospital after total knee arthroplasty, compared to the Daily living group, when it was applied to them, under the guidance of physical therapists. As research subjects, 20 patients that were scheduled to leave the hospital after unilateral total knee arthroplasty, were chosen, and they were randomly divided into a home physical therapy group(10 patients) and an Daily living group(10 patients) in order to conduct an experiment. During the 4-week research, home physical therapy was offered for 40 mins once for 5 days a week, and muscular strength, gait components were measured. For muscular strength, quadriceps muscle strength, hamstring muscle strength were measured, and as gait components, endurance, speed, step time, single-limb support were analysed. For this experiment, pre- and post-measurement were performed, and collected data were analyzed using SPSS ver. 18.0 statistical program. From the analysis of data, the following study results were obtained. Home physical therapy group and Daily living group both showed significant improvements in quadriceps muscle strength, hamstring muscle strength, and quadriceps muscle strength, hamstring muscle strength of home physical therapy group more significantly improved than Daily living group's. In relation to gait components, gait endurance, gait speed, step time significantly improved in both of home physical therapy group and Daily living group, whereas home physical therapy group only showed significant improvements in single-limp support. According to the comparison between two groups, gait speed, single-limp support and step time improved more significantly in the home physical therapy group than in the Daily living group. In conclusion, positive results were revealed in both home physical therapy group and Daily living group, with regard to muscular recovery of lower limbs of patients discharged from the hospital after total knee arthroplasty and walking, but considering the comparison results between two groups, it seems that applying home physical therapy is more effective than maintaining a daily life.

This study was carried out to investigate the residual sulfur dioxide residues (SO2) in commercial medicinal herbs in Korea in 2013. Among a total of 116 samples of 11 different kinds of herbs, 71 samples (11 Kinds) were domestic, and 45 samples (10 Kinds) were imported. The residual contents of SO2 in the samples were determinated by a modified Monier-Williams method. Of the 116 samples, 6 samples (5.2%, 4 Kinds) failed to meet the regulations for sulfur dioxide residues of KFDA in medicinal herbs. Among 6 unsuitable samples, 1 samples (1.4%) were domestic, and 5 samples (11.1%, 3 Kinds) were imported. The highest amount of sulfur dioxide residues was 1546.3 mg/kg (Lycii Fructus) in the domestic samples. Regardless of region, SO2 contents were not found at Anemarrhenae Rhizoma, Citri Unshius Pericarpium, Eucommiae Cortex, Forsythiae Fructus, Gardeniae Fructus, Leonuri Herba and Lonicerae Folium et caulis. These data will be used as a basic data for the future legislation on the regulation and control of sulfur dioxide of herbal medicines.

Experts of medicine, philosophy and psychology found that human somatotypes were related to personality or physical characteristics and classified somatotypes into various forms. This study explored the changes and types of somatotyping methods from Before Christ to present day and identified the status of studies of somatotypes in the area of physical therapy. This study covered the methods applied in various majors with a focus on those provided in books and papers of Heath BH. and Carter JEL. Based on the results, there are officially twelve assessment methods. Currently, the method of Heath & Carter is most widely applied. Somatotypes are studied in many areas. It is actively explored in the area of pain physical therapy, thermotherapy and integumentary physical therapy. Also, the soft tissue physical therapy area seeks interdisciplinary studies. This study found that there were various assessment methods in diverse areas. It is likely that continuous studies will develop new assessment methods. It is hoped that in the area of physical therapy, somatotypes shall be applied more amply.

The purpose of this study was to examine the influences of chronic shoulder pain on the muscle tone in trunk muscles. The study's subjects were 40 men and women in their 30 to 50s, which were divided into two groups. A chronic shoulder pain group consisted of 20 subjects who had been diagnosed with chronic shoulder pain by doctors, and a painless group consisted of 20 subjects who had experienced no such pain. An analysis was performed using electromyography on the muscle tone in the rectus abdominalis, external oblique, internal oblique, and erector spinae muscles under the same conditions between the two groups. The analysis results were as follows. The chronic shoulder pain group exhibited an overall high level of trunk muscle tone than the painless group, along with a statistically significant difference in the rectus abdominalis(p<.05). Moreover, the chronic shoulder pain group showed differences in the trunk muscle tone depending on the affected side. The chronic left shoulder pain group yielded higher levels of muscle tone in the right-side trunk muscles. In particular, the group revealed statistically significant differences in the rectus abdominalis and internal oblique(p<.05). The chronic right shoulder pain group exhibited higher levels of muscle tone in the left-side trunk muscles with a statistically significant difference in the internal oblique(p<.05). The above results suggested that chronic shoulder pain influences increases in the muscle tone in the trunk muscles on the opposite side to the affected shoulder.

The purpose of this study was to examine the degree of knowledge of care workers working at long term care hospitals and nursing homes on pressure ulcer. A total of 81 care workers including 34 at long term care hospitals and 47 at nursing homes were surveyed. 24 questions were used to evaluate their degree of knowledge on pressure ulcer. Their knowledge on pressure ulcer scored 12.84 out of the total score of 24 points(SD=3.40), which was equal to 53.50 (SD=24.23) out of 100 points. Their knowledge on the prevention of pressure ulcer was highest among the subareas of evaluation. Their knowledge on pressure ulcer statistically significantly differed according to education on pressure ulcer(P<.05). A pressure ulcer is a skin disorder that may be prevented and cured. At this point when long term care facilities are rapidly increasing, care workers highlevel knowledge on and good management of pressure ulcer is very important. Practically educating them on pressure ulcer including the provision of recent, updated relevant knowledge will be necessary.

The objective of this study was to determine the effects of E. coli isolated from porcine semen on sperm viability, motility, and semen pH. Semen samples were prepared using commercial extender, SeminarkPro (Noahbio Tech, Korea) that did not contain antibiotics. And 4 different levels of E. coli were artificially innoculated to semen with following concentrations; 4,000 of sperms with 1 of E. coli (T1), 400 with 1 (T2), 40 with 1 (T3), and 4 with 1 (T4). Semen samples were preserved at 17℃ for 5 days in semen storage box until analyzed by flowcytometer. Aliquots were subjected to measure the sperm viability (Live/Dead® stain), motility (mitochondrial function), and semen acidity (pH) from day 0 (day of semen collection) to day 5. Sperm motility and viability were significantly decreased (p<0.05) on day 0 (4 hrs after preservation at 17℃) in T3 and T4 compared to control groups and were significantly decreased (p<0.05) in all groups from day 3. Sample pH was acidic in T3 (6.90～6.86) and T4 (6.86～6.65) from day 3 to day 5 (p<0.05). On the other hand, sample pH was maintained 7.0～7.1 in control, T1, and T2 during the experimental period. Sperm motility and viability were significantly decreased from day 0 to day 5 compared to control in samples contaminated with E. coli above a value of 40:1 (20×106 sperm cells/ml : 5×105 cfu/ml). Even on day 1 in T4 and on day 3 in T3, semen pH was acidic probably due to the acidification of dead spermatozoa. These results suggest that E. coli contamination has a concentration-dependent detrimental effect on extended porcine semen quality.

The purpose of this study was to investigate the influence of handicraft activities on hand promptness and grasp in the elderly. Subjects were comprised of 14 senior citizens between the ages of 70-85, with 7 subjects in the experiment group and 7 in the control group. Subjects in the experiment group practiced various handicrafts twice a day, while those in the control group did not participate in any special activity. The Jebsen Taylor Hand Function Test was used to evaluate the results, while a dynamometer and pinch gauge were used to measure hand promptness and grasp. The 7 senior citizens in the experiment group were able to increase their hand promptness and grasping skills. Conclusively, handicrafts can help improve hand promptness and grasp in the elderly. Furthermore, the development and improvement of such skills can have a positive influence on the daily lives of senior citizens. Such skills are expected to improve the overall neuro-function in the elderly population.

The majority of strokes are caused by ischemia and result in brain tissue damage, leading to problems of the central nervous system including hemiparesis, dysfunction of language and consciousness, and dysfunction of perception. The purpose of this study was to investigate the effects of Poly(ADP-ribose) polymerase(PARP) on necrosis in neuronal cells that have undergone needle electrode electrical stimulation(NEES) prior to induction of ischemia. Ischemia was induced in male SD rats(body weight 300g) by occlusion of the common carotid artery for 5 min, after which the blood was reperfused. After induction of brain ischemia, NEES was applied to Zusanli(ST 36), at 12, 24 and 48 hours. Protein expression was investigated using immuno-reactive cells, which react to PARP antibodies in cerebral nerve cells, and Western blotting. The results were as follows: In the cerebral cortex, the number of PARP reactive cells after 24 hours significantly decreased(p<.05) in the NEES group compared to the GI group. PARP expression after 24 hours significantly decreased(p<.05) in the NEES group compared to the GI group. As a result, NEES showed the greatest effect on necrosis- related PARP immuno-reactive cells 24 hours after ischemia, indicating necrosis inhibition, blocking of neural cell death, and protection of neural cells. Based on the results of this study, NEES can be an effective method of treating dysfunction and improving function of neuronal cells in brain damage caused by ischemia.

We report relative proper motion measurements of H2O masers in massive star-forming region W51 Main, based on data sets of VLBI observations for H2O masers at 22 GHz with Japanese VERA telescopes from 2003 to 2006. Data reductions and single-beam imaging analysis are to measure internal kinematics of maser spots and eventually to estimate the three-dimensional kinematics of H2O masers in W51 Main. Average space motions and proper motion measurements of H2O masers are given both graphical and in table formats. We find in this study that W51 Main appears to be associated with hyper-compact H II region with multiple massive proto-stars whose spectral types are of late O.

Background : Haskap berries commonly refer to fruits of Lonicera caerulea L., recognized by the Japanese aborigines as the “The elixir of life.”. Due to their recent arrival on the North American market, haskap berries have not yet been positioned among other berries and compared in terms of their phytochemical content. And haskap berries have higher ascorbic acid and anthocyanin content than other berries known for their health-promoting benefits, such as blueberries. However, no study has reported on the antioxidant and anti-cancer activity of Lonicera caerulea stem. The purpose of this study is to present the current research on the chemical content, antioxidant and anti-cancer activities of Lonicera caerulea stem. Methods and Results : The stem of Lonicera caerulea L. ware dried in the shade at room temperature and extracted with 100% methanol. The extract was suspended in deionized water and partitioned sequentially with n-hexane, chloroform, ethyl-acetate and butanol (water saturated BuOH) fractions. Antioxidant activities were measured by determination of antioxidants, DPPH (2,2-diphenyl-1-picrylhydrazyl). Cell viability was determined by the MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide] assay. All cell lines were purchased from the Korean Cell Line Bank (Seoul, Korea). All results were performed with three replications were processed statistically. By DPPH assay, the Lonicera caerulea L. the highest activity was obtained from the ethyl-acetate fraction (IC50=15.46 ㎍/㎖). By MTT assay, the chloroform fraction showed a significant growth inhibiting effect on MCF-7 (Human breast cancer, IC50=225.91 ㎍/㎖), COLO 205 (Human colon cancer, IC50=179.55 ㎍/㎖), but on AGS (Human stomach cancer) and other fractions it did not show effect. Conclusion : We demonstrated that Lonicera caerulea L. stem extract and fractions has antioxidant and antiproliferation activity in vitro. Further studies should identify the active constituents in Lonicera caerulea L stem to evaluate the potential in vitro antioxidant and antiproliferation activities of the extract.

The Ponciri fructus immaturus (Poncirus trifoliata Rafinesque) has been used in oriental medicine for uterinecontraction, stomachache, abdominal distension and cardiovascular diseases. Two main compounds, poncirin and naringinwere successfully analyzed by high performance liquid chromatography (HPLC) and carried out method validation accordingto ICH guideline. A successful resolution and retention times were obtained with a C18 reversed phase column, at an 1㎖min−¹ flow rate, with a gradient elution of a mixture of methanol, water and acetonitrile. Poncirin and naringin showed goodlinearity (R²>0.999) in relatively wide concentration ranged. The recovery of each compound was 95.81~101.48% withR.S.D. values less than 1.0%. The application of ultrasound-assisted extraction was shown to be more efficient in extractingponcirin and naringin from Ponciri fructus immaturus. The predicted optimal poncirin and naringin yield were poncirin2.15%, naringin 1.65% under an extraction temperature of 40℃, an extraction time of 10 min in a solvent of 70% methanol.

Collected germplasms of five representative species belonging to Curcuma genus (C. longa, C. aromatica, C.zedoaria, C. phaeocaulis and C. kwangsiensis) were 52 samples from different farmhouse in Korea and China. To elucidatethe genetic diversity among the species, 52 samples were analyzed by genomic fingerprinting method using amplified frag-ment length polymorphism (AFLP). AFLP results of 6 primer combinations were revealed 643 total DNA fragments and349 polymorphic bands with the 54.3% ratio of polymorphism. In the analysis of coefficient similarity using unweight pairgroup method with arithmetic averages (UPGMA), 52 Curcuma germplasm lines were ranged from 0.60 to 0.99 and clus-tered distinct five groups according to the species and collected geographical levels. However, the result of principal coordi-nate analysis (PCA) by multi-variate analysis was shown significantly greater differences among species than geographicalorigins based on AFLP profiling data of these samples.

Plant biomass is a huge carbon-complex that has potential as a nutrient. Therefore we extracted and separated useful materials for plant growth from tea leaf and stem. The pre-treatment process including high temperature (200 °C) and pressure (20-40 kgf/cm2) was treated for several minutes and extracted at 120 °C for 30-60 minutes. After that the chemical compositions and ingredients were analyzed from that plantnutrient. As a result of mineral contents, calcium and magnesium concentrations are higher than other minerals. Also the result of carbohydrates analyses has shown that the sugar oligomer consists of xylose(95.3%) and glucose(4.7%), and the sugar monomer consists in the order of xylose (52.7%) > manose (22.8%) > arabinose (10.8%) > galactose (10.2%) > glucose (3.5%). Before applied to field, in vitro plant growth system and formulation were examined. To evaluate the effect of the nutrients, both strawberry green-house and persimmon fields were used in this test. The treated persimmons were heavier than controls scored at 13-22%. In addition, the storageperiod was extended in the treated strawberries. Interestingly in the treated strawberry, the contents of polyphenols were increased (38-57%). These results suggest that the plant-nutrient can afford to help for plant growth and storage, and it can be substituted for other commercial nutrients. In conclusion, this plant-nutrient may help to extend eco-friendly or organic farming in Hadong-gun area.
