  • Objectives : Standardization and clear description of locating acupuncture points guarantees reproducibility and credibility of the results in animal studies of acupuncture points and meridians. In this study, we aimed at analyzing the acupoint description of the previous experimental studies and suggesting guidelines for related journals. Methods : We searched animal studies where acupuncture points were used in Journal of Korean Acupuncture & Moxibustion Society and Journal of Meridian & Acupoint with a limitation of period, from 2002 to 2006. Data on experimental animals, acupuncture points and their descriptions were extracted and put in a predefined form. They were classified as one of the 4 classes; A) descriptions of the acupuncture points present, B) no description of the acupuncture points and only reference provided, C) neither description of the acupuncture points nor reference provided, or D) acupuncture point detector used. Two authors independently extracted and classified the data and the disagreements were resolved by discussion. Experts were invited to rate acupuncture point description validity on a numeric rating scale in the 11-item questionnaire. Results : Two hundred and five studies were identified and classified as follows; A) 32.2% (n=66), B) 7.8% (n=16), C) 51.2% (n=105), and D) 8.8% (n=18). Experts ratings were significantly lower for class C (mean${\pm}$SD, 2.14${\pm}$1.35, 95% CI [1.90, 2.39], P = 0.004 compared with class B, P ${\leq}$ 0.001 compared with class A or C) and no difference was found between classes A, B, and D. Conclusions : Reporting of acupuncture points in experimental animals is poor and validity and reliability of the result from such reporting is hampered. We suggest that journal editors and experts provide guidelines for reporting animal acupuncture points and adopt them into guide for authors for related journals.

  • The groundwater has been a major source of water supply throughout the ages. Around 50% of the rural as well as urban population in the developing countries like India depends on groundwater for drinking. The groundwater is also an important source in the agriculture and industrial sector. In many parts of the world, groundwater resources are under increasing threat from growing demands, wasteful use and contamination. A good planning and management practices are needed to face this challenge. A key to the management of groundwater is the ability to model the movement of fluids and contaminants in the subsurface environment. It is obvious that the contaminant source activities cannot be completely eliminated and perhaps our water bodies will continue to serve as receptors of vast quantities of waste. In such a scenario, the goal of water quality protection efforts must necessarily be the control and management of these sources to ensure that released pollutants will be sufficiently attenuated within the region of interest and the quality of water at points of withdrawal is not impaired. In order to understand the behaviour of contaminant transport through different types of media, several researchers are carrying out experimental investigations through laboratory and field studies. Many of them are working on the analytical and numerical studies to simulate the movement of contaminants in soil and groundwater of the contaminant transport. With the advent of high power computers especially, a numerical modelling has gained popularity and is indeed of particular relevance in this regard. This paper provides the state of the art of contaminant transport and reviews the allied research works carried out through experimental investigation or using the analytical solution and numerical method. The review involves the investigation in respect of both, saturated and unsaturated, porous media.

  • Objectives : Sleep Disorders are very common in clinical stages and there are many reports and papers regarding this subject. I try to understand the present state of sleep research in JON (The Journal of Oriental Neuropsychiatry) for the benefits of clinical practice. Methods : We searched and read every article on JON from 1990 to 2012 and selected ones that are related to Sleep Disorder; then analyzed the data to 5 categories, like literature study, case study, Clinical Data-Analysis study, experimental study, and clinical trial. Results : 1. We Found 41 articles relating to sleep disorder in JON form 1999 to 2012, and there were 9 literature studies, 13 case studies, 13 Clinical Data-Analysis studies, 4 experimental studies, and 2 clinical trials. 2. There were Sa-Am Acupuncture Method, Pharmacopuncture, electroacupuncture, and Auricular acupuncture to treat Sleep Disorder. 3. There were many additional treatments like Purgative Therapy, etc. 4. They reported the ordinary sleep pattern of Soeumin and Soyangin, too. 5. In the experimental study, they reported several herbs, herbal prescription on the expression of melatonin receptors, and Punsimgeimgamibang on insomnia, anxiety, emotionality in rats. 6. There were 2 clinical trials, one for Hwabyung-patient with insomnia by acupuncture treatment and another for insomnia in the elderly by ETF-I program. 7. There were 2 case of other sleep disorder (enuresis, sleepwalking) and 2 literature study of dream. Conclusions : In JON regarding sleep disorder, the majority was due to insomnia. Therefore, we also have to expand our sight into other sleep diseases. We need more clinical trials and experimental researches for the construction of EBM Sleep Disorder in Oriental Neuropsychiatry.

  • The purpose of this study was to identify trends in nursing research on multicultural family in Korea and suggest the direction for future research. A COSI model was used to guide the search process between the years 2008 and 2016, using the keywords 'cultural diversity', 'women', 'spouses', 'family', 'children' and 'nursing'. Of papers 137, 19 were doctoral dissertations, 10 were master's theses and 108 were from academic journals. Nursing research on internal married immigrant women has been steadily increasing since 2011. True experimental studies began in 2014 and most of the experimental studies were quasi-experimental studies. The research subjects were married immigrant women, and research on children, husband, mother-in-law and couple was very poor. The lack of information on the validity/reliability of the translated instruments were noted. The overall findings of this study suggest that future research should include more well-designed experimental studies. It is necessary to extend the study to husband and mother-in-law living with married immigrant women. Considering the ethnic background of the subject, it is necessary to develop a research tool with well-translated validity and reliability.

  • Purpose: Rodent models have emerged as an alternative to established larger animal models for peri-implantitis research. However, the construct validity of rodent models is controversial due to a lack of consensus regarding their histological, morphological, and biochemical characteristics. This systematic review sought to validate rodent models by characterizing their morphological changes, particularly marginal bone loss (MBL), a hallmark of peri-implantitis. Methods: This review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. A literature search was performed electronically using MEDLINE (PubMed), and Embase, identifying pre-clinical studies reporting MBL after experimental peri-implantitis induction in rodents. Each study's risk of bias was assessed using the Systematic Review Center for Laboratory animal Experimentation (SYRCLE) risk of bias tool. A meta-analysis was performed for the difference in MBL, comparing healthy implants to those with experimental peri-implantitis. Results: Of the 1,014 unique records retrieved, 23 studies that met the eligibility criteria were included. Peri-implantitis was induced using 4 methods: ligatures, lipopolysaccharide, microbial infection, and titanium particles. Studies presented high to unclear risks of bias. During the osseointegration phase, 11.6% and 6.4%-11.3% of implants inserted in mice and rats, respectively, had failed to osseointegrate. Twelve studies were included in the meta-analysis of the linear MBL measured using micro-computed tomography. Following experimental peri-implantitis, the MBL was estimated to be 0.25 mm (95% confidence interval [CI], 0.14-0.36 mm) in mice and 0.26 mm (95% CI, 0.19-0.34 mm) in rats. The resulting peri-implant MBL was circumferential, consisting of supra- and infrabony components. Conclusions: Experimental peri-implantitis in rodent models results in circumferential MBL, with morphology consistent with the clinical presentation of peri-implantitis. While rodent models are promising, there is still a need to further characterize their healing potentials, standardize experiment protocols, and improve the reporting of results and methodology.

  • Objectives The study was conducted to evaluate the acupuncture treatment for burns by reviewing international randomized controlled studies and case controlled studies. Methods In the review, ten academic literature archives; NDSL, OASIS, PubMed, Cochrane library, CNKI, WANFANG, CINAHL, J-STAGE, CiNii, and EMBASE were used as the main databases to search for the randomized controlled trials or the case controlled trials about acupuncture treatment of burns using the keywords "burns AND acupuncture", "burn AND acupuncture", and "scald AND acupuncture". Results Initially, a total of 852 studies were founded except duplicate studies. 801 studies were excluded after screening of title and abstract. After reviewing 51 papers, a total of four randomized controlled trials and two case controlled trials were selected. These studies were analyzed by year, subjects, treatment intervention, evaluation criteria, treatment effect, adverse events, and 'Risk of Bias' assessment for randomized studies and non-randomized studies. From the six papers out of 51 papers those were reviewed, patients with burns were divided into two groups. The experimental group received acupuncture treatment, while the control group did not. The results of the completed studies have shown that the experimental group receiving acupuncture treatment demonstrated significant improvement compared to the control group, and there was no serious adverse events. Conclusions According to some of the studies, acupuncture in burn treatment is worth to try. However, additional well-designed randomized controlled studies will be required to justify the effectiveness of acupuncture treatment of burns.

  • This is a systematic review of the clinical use of cupping therapy. Four domestic databases and 2 foreign databases were searched. Studies that reported the cupping pressure used during cupping therapy were included in this study. The types of cupping, cupping site, pressure, and duration of cupping were the main parameters analyzed. A total of 27 studies, including 24 experimental studies were analyzed. There were 12 constant negative pressure (domestic) studies with a range between 60 mmHg and 600 mmHg. There were 5 maximum negative pressure (domestic) studies and the maximum negative pressure was 620 mmHg. Three studies used a maximum negative pressure of 600 mmHg. There were 4 constant negative pressure (foreign) studies with a range between 75 mmHg to 750 mmHg. There were 3 maximum negative pressure (foreign) studies with a maximum pressure of 420 mmHg. The studies differed with regards to the materials used and the amount of pressure applied. Many studies had limited information and therefore generalizability of the results in this review is limited. Further experimental studies are required to establish the correlation between cupping pressure and treatment effects so that cupping therapy can be standardised.

  • Experimental and computational studies were performed to determine the effects of different blade designs on a flow pattern inside a double-spindle counter rotating mower deck. In the experimental study, two different blade models were tested by measuring air velocities using a forward-scatter LDV system. The velocity measurements were taken at several different azimuth and axial sections inside the deck. The measured velocity distributions clarified the air flow pattern caused by the rotating blades and demonstrated the effects of deck and blade designs. A high-speed video camera and a sound level meter were used for flow visualization and noise level measurement. In the computational works, two-dimensional blade shapes at several arbitrary radial sections have been selected for flow computations around the blade model. For three-dimensional computation applied a non-inertia coordinate system, a flow field around the entire three-dimensional blade shape is used to evaluate flow patterns in order to take radial flow interactions into account. The computational results were compared with the experimental results.

  • Numerical and experimental studies were performed to investigate the aerodynamic performance of a thin wing in close vicinity to the ground. The vortex lattice method (VLM) was utilized to simulate the wing in ground (WIG) effect, which included freely deforming wake elements. The numerical results acquired through the VLM were compared to the experimental results. The experiment entailed varying the ground clearance using the DHMTU (Department of Hydromechanics of the Marine Technical University of Saint Petersburg) wing and the WIG craft model in the wind tunnel. The aero-dynamic influence of the design parameters, such as angles of attack, aspect ratios, taper ratios, and sweep angles were studied and compared between the numerical and experimental results associated with the WIG craft. Both numerical and experimental results suggested that the endplate augments the WIG effect for a small ground clearance. In addition, the vortex lattice method simulated the wake deformation following the wing in the influence of the ground effect.
