The present study investigated the role of peripheral group I, II, and III metabotropic glutamate receptors (mGluRs) in mustard oil (MO)-induced nociceptive response in the masseter muscles of lightly anesthetized rats. Experiments were carried out on male Sprague-Dawley rats weighing 300-350 gm. After initial anesthesia with sodium pentobarbital (40 mg/kg, i.p.), one femoral vein was cannulated and connected to an infusion pump for intravenous infusion of sodium pentobarbital. The rate of infusion was adjusted to provide a constant level of anesthesia. MO (30 ${\mu}L$) was injected into the mid-region of the left masseter muscle via a 30-gauge needle over 10 seconds. After 30 mL injection of 5, 10, 15, or 20% MO into the masseter muscle, total number of hindpaw-shaking behavior was monitored. Intramuscular administration of MO significantly produced hindpawshaking behavior in a dose-dependent manner, as compared with the vehicle (mineral oil)-treated group. Intramuscular pretreatment with 10 or 100 ng DHPG, a group I mGluRs agonist, enhanced MO-induced hindpaw-shaking behavior, while APDC (20 or 200 ${\mu}g$), a group II mGluRs agonist, or L-AP4 (2 ${\mu}g$), a group III mGluRs agonist, significantly reduced MO-induced nociceptive behavior. The antinociception, produced by group II or III mGluRs agonists, was abolished by pretreatment with LY341495, a group II mGluRs antagonist, or CPPG, a group III mGluRs antagonist, res-pectively. Based on these observations, peripheral mGluRs differentially modulated MO-induced nociceptive behavior response in the craniofacial muscle pain and peripheral group II and III mGluRs agonists could be used in treatment of craniofacial muscle nociception.

The proper position of a multi-leaf collimator (MLC) is essential for the quality of intensity-modulated radiation therapy (IMRT) and volumetric modulated arc radiotherapy (VMAT) dose delivery. Task Group (TG) 142 provides a quality assurance (QA) procedure for MLC position. Our study investigated the QA validation of the mechanical leaf gap measurement and the maintenance procedure. Two $VitalBeam^{TM}$ systems were evaluated to validate the acceptance of an MLC position. The dosimetric leaf gaps (DLGs) were measured for 6 MV, 6 MVFFF, 10 MV, and 15 MV photon beams. A solid water phantom was irradiated using $10{\times}10cm^2$ field size at source-to-surface distance (SSD) of 90 cm and depth of 10 cm. The portal dose image prediction (PDIP) calculation was implemented on a treatment planning system (TPS) called $Eclipse^{TM}$. A total of 20 VMAT plans were used to confirm the accuracy of dose distribution measured by an electronic portal imaging device (EPID) and those predicted by VMAT plans. The measured leaf gaps were 0.30 mm and 0.35 mm for VitalBeam 1 and 2, respectively. The DLG values decreased by an average of 6.9% and 5.9% after mechanical MLC adjustment. Although the passing rates increased slightly, by 1.5% (relative) and 1.2% (absolute) in arc 1, the average passing rates were still within the good dose delivery level (>95%). Our study shows the existence of a mechanical leaf gap error caused by a degenerated MLC motor. This can be recovered by reinitialization of MLC position on the machine control panel. Consequently, the QA procedure should be performed regularly to protect the MLC system.

This is an underlying study for expanding child growth and developmental screening program, which had been implemented as a part of maternal child health service in a certain public health center located in P City. This study attempted to develop system model to discover, consult and follow-up developmental disabilities in children in early stage. For the purpose of providing groundwork for further development of screening program, the system model was analyzed and evaluated. One of the focuses of this study was developing practical tool that can aid small number staffs of public health center to handle large number of patients. 9 types of developmental checklist by key month was developed to support understaffed public health center. These checklists were also supplied to other public health centers, greatly improving qualitative and quantitative development of screening project. Also, the 4-step program of operating and managing child growth and developmental screening was proved to be quite effective. Total 632 children were evaluated and 21 of them were suspected to have developmental problem. Among these children, 8 children were determined to receive regular supervision of public health center. Other 13 children were recommended to visit professional institution, but only 7 of them actually visited institution. Four of these children who visited professional institution are currently receiving treatment, while the other 3 children were determined to require close observation. Five times of screening education were provided to the staffs in public health center and personnel in charge of children in every district public center in P City. The purpose of this training was to improve individuals' capability to implement project and to establish basis for expanding child growth and developmental screening program. The participants were guided to have continuous attention for the project, and their knowledge, skill and recognition were greatly improved through educational training. Also, professional child consulting and education, including lecture for baby food and baby food menu exhibition, were given to parents. Through this opportunity, parents acquired higher understanding about baby food while the local residents' recognition for maternal child health service was greatly improved.

Purpose: The study aimed to extract the space mentioned in the criteria for evaluation and certification of psychiatric institutions in which the most specific standards for medical services of psychiatric institutions are prepared, and to organize and analyze the requirements. Method: The implied space is derived by analyzing the evaluation and certification criteria. The derived space is re-classified by departments of the hospital, and the requirements are organized and analyzed. Results: First, a total of 41 spaces were derived. The derived spaces can be considered as spaces to be treated as important in psychiatric institutions. Second, as a result of reclassifying the derived space by department, 10 spaced for the hospital as a whole, 10 for wards, 12 for central/outpatient departments, 5 for pharmaceutical departments, 2 for catering facilities, and 2 for facilities. Third, if organized by psychiatric institution, there is a total of 40 spaces for psychiatric hospitals according to certification criteria, and according to evaluation criteria, there is 38 spaces for psychiatric hospitals and departments and 19 spaces for the clinics. The difference between the certification and evaluation criteria of psychiatric hospitals is insignificant. In order to promote the qualitative improvement of psychiatric institutions, it is necessary to gradually strengthen from the certification criteria. Fourth, the requirements reflecting the characteristics of a psychiatric institution were very limited to emergency exits and treatment rooms. It is necessary to prepare the space requirements for other rooms in consideration of the behavior of the mentally ill. Implications: The derived spaces and requirements can serve as practical reference materials for practitioners preparing to receive certification and evaluation of psychiatric institutions. In addition, it has meaning as a basic data for estimating the level of space and requirements of psychiatric institutions that are currently required in Korea.

Cervical cancer, the second most common malignancy all over the world, is associated with HPV infection. In a developing country like India, lack of early detection and treatment facilities is the main cause for its high burden. Therefore, through our study we e tried to present the current scenario of existing facilities for the detection and treatment of cervical cancer in hospitals and primary health centers (PHCs) of Delhi-NCR region. Data were collected from 312 healthcare facilities including public and private hospitals and PHCs of all nine districts from Delhi-NCR region. Healthcare providers including gynecologists, medical officers, women health care providers and paramedical staff were interviewed, using a questionnaire; the facilities for screening, diagnosing, and treating cervical cancer in each institution were recorded, using a previously designed checklist. Our study has shown that the basic facilities for the detection and treatment of cervical cancer are abhorrently lacking in Public hospitals and PHCs as compared to the Private hospitals in Delhi-NCR region. This study demonstrates that there is an urgent need for more investment in the diagnosis and treatment of cervical cancer facilities in public and rural healthcare facilities of Delhi-NCR region.

Purpose: Clinical characteristics and medical cost were analyzed according to the surgical procedures for intertrochanteric fracture in aged patients to assess the appropriateness of treatment expense and to find possibility of reducing the medical cost. Method: Variable for the statistical analysis were; the clinical characteristics, medical cost according to the surgical procedures, the treatment success rate, the total medical expense, and the average expense per case. SAS Package Version 8.02. was used to analyze the relevant data. Results: Operative procedures differ significantly according to the gender and by the location of institution. Only significant clinical variables according to the operative procedure were duration of general anesthesia and amount of blood transfusion. Average cost per treatment was the highest in the bipolar hemiarthroplasty followed by the gamma nail and hip compressing screw. Average cost for bipolar hemiarthroplasty was significantly higher than other surgical procedures. Conclusions: The difference in hospital costs for treatment of intertrochanteric fracture originates from the utilized surgical procedures, mostly by the materials used. The method of surgical treatment should be carefully determined by the purpose of the surgery, in order to improve the quality of medical care and also to reduce the hospital cost.
