The purpose of this study was to discuss the papers of social welfare field that were published in Korea, from a research methodology aspect in accordance with the meta-analysis reporting standard proposed by the United States Psychological Association. To this end, an analysis was conducted according to 5 types of conformity (title and abstract, introduction, methods, results and discussion) on the target subjects of 26 meta-analysis papers of social welfare field. The analysis results showed, first, the conformity in the title and abstract showed good results except for the suggested topics for meta-analysis methods. Second, in terms of the conformity of the introduction, the descriptions seemed to be good in a number of items. Third, for the conformity in the methods, the overall reporting standard was seen to be lacking and, in particular, the reporting standard for the coding procedure was seen as being very deficient. Fourth, the conformity in the results showed that the assessment of research quality and the magnitude of efficacy for each individual study, sample size, and the contents of the provided tables, summary of tables and graphs, including the study results, were not being properly reported. Fifth, the conformity in discussions was seen to be generally sound. Based on such results, by providing a reporting standard and perspective needed for ensuring feasibility that can be used to assess meta-analysis study materials, this study was aimed at presenting implications for the academic advancement of field of social welfare.

This study evaluated the standardization of the outpatient management process in several regions of South Korea. The hospital workers in the administration department of the different medical institutions that are registered with the Korean Hospital Association were surveyed. These institutions can be standard hospitals or hospitals greater in size. A summary of the research results are as follows. There was no significant correlation in their registration procedures in relation to the institution's founder, number of sickbeds, number of staff employed in the administration department, and average number of outpatients per day. On the other hand, the prepayment of medical fees occurred more frequently when the number of sickbeds was larger. In addition, there was no large difference in their appointment procedures in relation to those features. Nevertheless, the prepayment of medical fees accounted for 11.8 % of the entire payment in institutions with less than five hundred beds, while fifty percent of the payment was made in advance in larger institutions with five hundred or more beds. From this research, there was only a small difference among the institutions' outpatient management, but a notable difference was observed in their electronic data processing systems and facilities. Therefore, more financial support should be generated for the implementation of a more integrated process. As a follow-up study, to provide patients with quality medical services, it will be necessary to apply the standardized procedure to an actual medical institution and analyze the expected effect.

To assess the effectiveness of subxipoid pericardial drainage for the treatment of pericardial effusion, we reviewed 80 cases of subxiphoid pericardial drainage between January 1986 and December 1995. There were 39 males and 41 females with ages ranging from 20 to 80 years. The diagnosis of pericardial effusion was made by echocardiography. The procedure was carried out under general anesthesia in 50(62.5%) and under local anesthesia in 30 patients(37.5%). Among the 33 p tients with malignant pericardial effusion, cytology was positive .in 14 of 31(45%), and pericardial biopsy showed malignancy in 7 of 29 patients(24%). Among the 27 patients with tuberculous pericardial effusion, the diagnosis was confirmed by histology of pericardial biopsy in 12 patient or bacteriologic culture in 1 patient. The operative mortality was 17.5% (14180 patients) and all the mortality occurred in the malignant group. There were no operation-related mortality Sixty six patients were followed from 9 days to 5 years; mean follow-up was 452 days. Recurrent pericardial effusions, necessitating further surgical intervention, occurred in 6 (7.5%) patients. Constrictive pericarditis developed later in 4 patients(5%) and two of them had undergone complete pericardiectomy. In summary, subxiphoid pericardial drainage allowed safe and efficient drainage of pericardial effusions with sampling for cytology and pericardial biopsy, and had an acceptable morbidity and mortality.

Two studies were conducted to determine the effects of replacing 30% (% in diet DM) of lucerne (Medicago sativa L.) hay with citrus pulp in Merino ewe diets: i) an in vitro study which measured ruminal fermentation; and ii) an in vivo study in which twelve Merino ewes pre- and post-lambing were fed experimental diets in a cross-over design over 120 days to evaluate effects on ewe performance (i.e. DM intake, average daily gain (ADG) and wool growth). In both the in vitro and in vivo studies, the control treatment consisted of lucerne (91.3% in diet DM), lupins (8.3% in diet DM) and phosphate (0.42% in diet DM), while the citrus pulp treatment consisted of lucerne (57.7% in diet DM), lupins (9.5% in diet DM), phosphate (0.48% in diet DM) and fresh citrus pulp (32.3% in diet DM). Data were analysed using the mixed model procedure of SAS. In the in vitro study, gas production, total volatile fatty acid (VFA) yield, proportion of propionic acid to total VFA and in vitro dry matter digestibility (IVDMD) were higher (p<0.02) in the citrus pulp treatment compared to the control treatment. In contrast, in vitro ammonia production, pH and the acetate to propionate ratio were lower (p<0.03) for the citrus pulp treatment compared to the control treatment. In the in vivo study, DM intake of ewes fed the citrus pulp diet was lower than their control ewe counterparts throughout both the pre- and post-lambing periods (928.9 vs. 1,115.0 g/d pre-; 1,285.0 vs. 1,620.3 g/d post-lambing, p<0.01), however ADG was similar (p = 0.12). Wool growth parameters and lamb performance did not differ (p>0.32) between treatments. In summary, the in vitro study demonstrated that the replacement of 30% of a lucerne diet with fresh citrus pulp improved total VFA yield, increased total gas production and improved IVDMD, while decreasing the production of ammonia, acetic acid and rumen pH. In addition, the in vivo study demonstrated that the replacement of 30% of a lucerne diet with fresh citrus pulp pre- and post-lambing decreased intake but did not affect ewe performance in terms of ADG and wool growth. These findings, of course, would be of significant interest to sheep producers endeavouring to control cost of feed ingredients whilst maintaining productivity.

The purpose of this study was to determine factors influencing patient satisfaction with medical services in hospital, which is classified into environmental aspect, human services and procedural services. Based on the results of literature review, the study focused on effects of social-demographical factors on patient satisfaction. The environmental aspect of medical care services included medical equipment and facilities, hygiene, ventilation, heating and air-conditioning, waiting and resting space, ward space and parking facilities. Procedural service included registration process, bill payment, waiting time after registration, examination and prescription as well as appointment process. Human services consisted of physicians listening to stories of patients, examination duration, physicians' explanation and physicians' service. As for nurses, explanation about disease, examination procedure and results, kindness and nursing care were evaluated. Services provided by other staff members were also evaluated. Patient satisfaction, defined as individual attitude toward medical service as a whole, was measured using a questionnaire. A total of 700 in-or out-patients were surveyed in 6 hospitals with more than 300 beds in North Gyeongbuk Province. 1. The level of patient satisfaction varied with characteristics of patients. Male patients and those in their 30s had a low level of satisfaction. Dissatisfaction level was positively related to education level but negatively related to economic condition. 2. As for patient satisfaction with medical service providers and other employees in hospital, satisfaction level with physician's explanation about treatment was higher. But dissatisfaction levels with treatment duration and the lack of explanation about examination procedures were high, calling for improvement. Dissatisfaction level with nursing care was high, calling for training of nurses for better service. Given the low level of satisfaction with human services, hospital employees need to be trained to improve their service. 3. It Was found that administrative service was also a significant factor influencing patient satisfaction in addition to medical service. It is therefore important for hospitals to provide patients with prompt and convenient procedural service. 4. Environmental factors such as medical equipment and amenity facilities also affected patient satisfaction. Thus environmental condition, procedural service and human service are all important to improve medical service in hospital. In summary, procedural service was the most significant factor for patient satisfaction. The level of satisfaction in patients was also affected by human service and environmental condition. It is therefore necessary to take patient-oriented approach in providing medical service in an effort to improve patient satisfaction. The finding of a lower level of satisfaction with human service signifies the need for training of healthcare providers and other hospital employees for better services. The introduction of advanced management programs is also needed to improve procedures that patients go through in hospitals.

A method using liquid chromatography-tandem mass spectrometry (LC-MS/MS) was developed for neonicotinoid pesticide analysis in agricultural products. Four compounds (imidacloprid, clothianidin, acetamiprid, thiacloprid) were extracted with acetonitrile from agricultural products and cleaned up by NH₂ solid-phase extraction procedure, and eluted with 0.1% formic acid in methanol/dichloromethane (5/95, v/v). The limit of detection and quantification were 0.0001-0.0005 mg/kg and 0.001 mg/kg, respectively. The mean recoveries of neonicotinoid pesticide from agricultural products were in the range of 90.7-100.9% and 94.4-99.8%, as spiked at 0.2 mg/kg and 0.02 mg/kg, respectively. This validation satisfied the national criteria for pesticide analytical methods. In summary, The present method is fast, precise and sensitive enough for the Positive List System (PLS), and we conclude that the method is also suitable for neonicotinoid pesticide determination in a wide range of agricultural products.

Pediatric dentists are frequently encountered with fractured root fragments of primary teeth caused either by the traumatic injuries or by the accidental fractures during the procedure of tooth extractions. In these situations, we often hesitate which method to choose, extract or retain it. In general, it is recommended to retain apical fragments, as the attempts to extract the apical fragments might harm the developing permanent tooth germ. This study was designed to ensure the validity of intentional retention of the root fragments of primary teeth in the situations described above. 6 children with intentionally root fragments who experienced root fracture in primary anterior teeth were available Periodic radiographic assessment was performed at 3 months interval for $7{\sim}37$ months. The results of this study showed that apical fragments had been resorbed through physiologic process in 5 patients. Apical fragment had been gingival emergence along with the erupting permanent tooth in 1 patient. There were no evidence of interference with eruption of permanent successors. In summary we have been ensured the validity of intentionally retention of the root fragments of primary teeth. Children with being remained apical root fragment should be recalled regularly for assessment and parents should be thoroughly informed about the situation with special emphasis on the necessity of periodic check-up.

The purpose of this study was to develop cooperative learning model by utilizing mind practice to build mutual understandings and reliability among team members at the early stage of cooperative learning model That is to say, mind practice was applied to make the team members understanding one another and building the member's mutual confidences. The study was performed by dividing into two stages. First, the draft of mind practice based on cooperative learning model was proposed by performing a literature survey and a case study. Second, the draft model was applied to actual classrooms. And the draft was modified and developed to the final model on the basis of the draft model's strength and improvement founded during the procedure of the actual application. This draft model was implemented to 46 students who were the sophomore of department of education and enrolled the profession class of "Education methodology and Education engineering" at J college in J city for 5 weeks. From the implementation result of the model, it was obtained that there was the positive reaction on applying mind practice to the beginning stage of cooperative learning. Adding of "Re-building team" step in the original steps was suggested. The final model was modified and issued based on the research result. In summary, it was concluded that cooperative learning model based on mind practice could not only provide the harmonious interactions among team members at the step of "building the team members" but also have a positive effect on refreshing learning atmosphere of the team.

Pulmonary sequestration (PS) is a rare congenital malformation of the lower respiratory tract. The anomaly is characterized by absence of communication with the tracheobronchial tree and isolated blood supply from an anomalous systemic vessels. With the utilization of antenatal ultrasound, the diagnosis of asymptomatic neonatal PS has increased. Treatment options include observation, arterial embolization and surgical resection. The aim of the present study is to review the clinical course of PS and to share our experience with thoracoscopic resection. A total of 96 patients with PS were treated at Asan Children's Hospital between 1999 and 2010. The diagnosis of PS was established by CT in the cases managed by observation or embolization, and by tissue pathology in the surgical cases. Medical records and radiographic images were retrospectively reviewed. Thirty-nine patients were managed by embolization and 30 patients by surgery. The remaining 27 patients have been under observation without any procedures. Among 27 observation patients, 1 patient regressed completely and 10 patients were lost to follow up. Of the 39 embolizations patients, 2 had their lesion regress and sepsis was suspected after embolization. In 1 patient, the microcoil migrated to the iliac artery during the embolization procedure, and another patient developed renal abscess caused by renal artery embolization. Among 30 surgical cases, resection by thoracotomy was performed in 27 at the Department of Thoracic Surgery, and thoracoscopic resection in 3 at the Division of Pediatric Sugery. Only one wound complication ocurred. We conclud that surgical excision should be recommended for pulmonary sequestration, whether the sequestration is symptomatic or not because of the risk of infection, the low rate of natural regress, poor compliance, severe complications after embolization, and to exclude other pathology. In summary, thoracoscopic resection of the pulmonary sequestration is feasible, efficacious, safe and cosmetically superior even in neonatal period.
