Purpose: This study was conducted to examine and compare satisfaction with Korean health care services for Americans, Chinese and Russians who resided in Korea. Methods: A questionnaire was distributed to 252 participants (81 Americans, 89 Chinese, 82 Russians). Three focus group interviews were subsequently conducted in order to obtain a greater understanding of participants' experience and perspectives. Results: The average satisfaction score was 3.09, with Americans and Russians showing significantly higher scores than Chinese. Overall, participants reported higher satisfaction in 'Facility', 'Quality of care' and 'Nursing services' as opposed to 'Information/education'. 'Care with cultural respect' as well as communication related services. Data from the focus group interviews were categorized into 12 sub-categories, 7 categories and 2 themes. The two themes were common experience and contrasting experience. Common experience included 4 categories, 'Quality of care', 'Hospital facility and health care system', 'Language barrier' and 'Information and education'. Contrasting experience included 3 categories, 'Medical cost', 'Health care personnel' and 'Accessibility'. Conclusion: Results of this study provide basic knowledge on foreign residents' satisfaction and experience with Korean health care services. Further research is needed with foreigners from different cultural backgrounds. Administrative and educational efforts are required to improve communication skills and cultural competency.

This study is to analyze the efficiency of Korean sea food manufacturing using Data Envelopment Analysis. Firstly, based on an output oriented traditional CCR, BCC model, the study estimated the efficiency scores. The average estimates of technical, pure technical, and scale efficiency turned out 0.6517, 0.7184, 0.9074 respectively, which are separated for 50 marine corporations. The 10 DMUs were efficient under CCR model while the 17 DMUs under BCC model. Also, the study suggested that the operating profit of the two output factors should be more increased relatively and averagely from the viewpoint of efficiency improvement. Secondly, super efficiency scores are estimated under super efficiency and SBM model. As a result, it came to be possible to distinguish and rank the efficiency of the efficient DMUs. The highest score was 4.2975 under Super-CCR, was 2.4947 under Super-BCC, was 2.7160 under SBM-Super-CCR, and was 1.5319 under SBM-Super-BCC model. The average estimates of super efficiency were 0.76 and 0.82 under Super-CCR and Super-BCC model respectively, and were 0.61 and 0.67 under SBM-Super-CCR and SBM-Super-BCC model. Finally, the study conducted a rank-sum test, Wilcoxon-Mann-Whitney test, to find a statistical significance of heterogeneity existing in efficiencies among the sample corporations. The result showed that there was a significant difference in average efficiency between Dried, Salted product manufacturing and Frozen product manufacturing under BCC-Super efficiency model at 10% level of significance. Furthermore, TOBIT model was applied to find out the potential factors that might influence the efficiency, Wilcoxonand the results showed debt and sales cost influenced all of the technical, pure technical, and scale efficiency, while net profit influenced only the technical efficiency.

Background: Posttraumatic acquired facial deformities require surgical treatment, with options including scar revision, fat grafts, implant insertion, and flap coverage. However, each technique has specific advantages and disadvantages. Methods: From 2016 to 2018, 13 patients (eight with scar contracture and five with a depressed scar) were treated using dermofat grafts from the groin. The harvested dermofat was then inserted into the undermined dead space after the contracture was released, and a bolster suture was done for fixation considering the patient's contour and asymmetry. A modified version of the Vancouver Scar Scale and satisfaction survey were used to compare deformity improvements before and after surgery. Results: In most cases, effective volume correction and an aesthetically satisfactory contour were maintained well after dermofat grafting, without any major complications. In some cases, however, lipolysis proceeded rapidly when inflammation and infection were not completely eliminated. A significant difference was found in the modified Vancouver Scar Scale before and after surgery, with a p-value of 0.001. The average score on the satisfaction survey was 17.07 out of 20 points. Conclusion: A dermofat graft with the groin as the donor site can be considered as an effective surgical option that is the simplest and most cost-effective method for the treatment of acquired facial deformities with scar contracture.

지하에 매설되어 있는 도시가스배관은 부식성 없는 유체이기 때문에 화학플랜트배관보다는 상대적으로 안전하다. 그러나, 도시가스는 일반적으로 도심지역에 공급됨으로 공급지역의 여러 간섭시설물과 환경에 의한 부식과 시설물의 굴착공사로 야기되는 제 3자 사고등으로 큰 사고를 야기할 수 있다. 특히 지하매설된 배관이므로, 배관의 손상여부를 파악하고 검사하는 것이 상당히 난해하다. 따라서, 본 고에서는 지하매설배관의 위험성 개념을 도입하여, 위험지역 배관을 선정하여 관리하는 것으로 접근하였다. 여기서 위험성은 부식요인, 설계 및 시공요인, 유지관리요인으로 파악하여 나타내었고, 배관의 정성적인 위험성을 점수로 표현하여, 정량적인 숫자로 표현하였다. 또한 Key 인자 개념과 비용에 대한 손상보완대책 개념을 프로그램에 도입하여, 신뢰성과 안전경영에 도움이 되리라 생각된다. 본 위험성 평가 프로그램은 비쥬얼 베이직을 사용하여 개발하였고, GIS와 연계하였다.

Temporal hollowing occurs to varying degrees after pterional craniotomy. The most common cause of temporal hollowing is a bony defect of the pterional and temporal regions due to the resection of the sphenoid ridge and temporal squama for adequate exposure without overhang. The augmentation of such bony defects is important in preventing craniofacial deformities and postoperative hollowness. Temporal cranioplasty has been performed using a range of materials, such as acrylics, porous polyethylene, bone cement, titanium, muscle flaps, and prosthetic dermis. These methods are limited by the risk of damage to adjacent tissue and infection, a prolonged preparation phase, the possibility of reabsorption, and cost inefficiency. We have developed a method of temporal augmentation using a calvarial onlay graft as a single-stage neurosurgical reconstructive operation in patients requiring craniotomy. In this report, we describe the surgical details and review our institutional outcomes. The patients were divided into pterional craniotomy and onlay graft groups. Clinical temporal hollowing was assessed using a visual analog scale (VAS). Temporal soft tissue thickness was measured on preoperative and postoperative computed tomography (CT) studies. Both the VAS and CT-based assessments were compared between the groups. Our review indicated that the use of an onlay graft was associated with a lower VAS score and left-right discrepancy in the temporal contour than were observed in patients undergoing pterional craniotomy without an onlay graft.

The effects of housing and nutrition on the performance of first lactation sows of the Nepalese Pakhribas breed were investigated. A total of 36 sows, from a previous experiment on nutrition during gilt rearing, were allocated according to a factorial design with 2 levels of nutrition, 60 or 80% of the calculated lactation requirement, and two types of housing, traditional or improved. The mean live weight loss of sows during lactation was reduced to a slightly greater extent by improved housing (p<0.05) than by better nutrition (p<0.10). There was also a significantly lower loss of $P_2$ backfat thickness (p<0.05) and mean body condition score (p<0.05) for sows on the higher plane of nutrition. Piglet weight gain in early and mid lactation was influenced by gestation feeding of the gilt (p<0.10) and by housing (p<0.05). Late lactation gain was influenced only by lactation feeding (p<0.05). In consequence, piglet weight at 42 day weaning was increased to a similar extent by improved housing (p<0.05) and better lactation nutrition (p<0.01). Significantly more sows were remated by day 10 after weaning from a higher level of rearing nutrition ($x^2=13.57$, p=0.001), and from improved housing and improved lactation (both $x^2=4.57$, p=0.033). It is concluded that, under Nepalese village conditions, improvements in housing may be a more cost effective way of improving sow performance than expenditure on additional feed resources.

Objective : Traditionally, staged surgery has been preferred in the treatment of compound comminuted depressed fracture (FCCD) after traumatic brain injury (TBI) and involves the removal of primarily damaged bone and subsequent cranioplasty. The main reason for delayed cranioplasty was to reduce the risk of infection-related complications. Here, the author performed immediate reconstruction using a titanium mesh in consecutive patients with FCCD after TBI, reported the surgical results, and reviewed previous studies. Methods : Nineteen consecutive patients who underwent single-stage reconstruction with titanium mesh for FCCD of the skull from April 2014 to June 2018 were retrospectively analyzed. The demographic and radiological characteristics of the patients with FCCD were investigated. The characteristics associated with surgery and outcome were also evaluated. Results : The frequency of TBI in men (94.7%) was significantly higher than that in women. Most FCCDs (73.7%) occurred during work, the rest were caused by traffic accidents. The mean interval between TBI and surgery was 7.0±3.9 hours. The median Glasgow coma scale score was 15 (range, 8-15) at admission and 15 (range, 10-15) at discharge. FCCD was frequently located in the frontal (57.9%) and parietal (31.6%) bones than in other regions. Of the patients with FCCDs in the frontal bone, 62.5% had paranasal sinus injury. There were five patients with fractures of orbital bone, and they were easily reconstructed using titanium mesh. These patients were cosmetically satisfied. Postoperatively, antibiotics were used for an average of 12.6 days. The mean hospital stay was 17.6±7.5 days (range, 8-33). There was no postoperative seizure or complications, such as infection. Conclusion : Immediate bony fragments replacement and reconstruction with reconstruction titanium mesh for FCCD did not increase infectious sequelae, even though FCCD involved sinus. This suggests that immediate single-stage reconstruction with titanium mesh for FCCD is a suitable surgical option with potential benefits in terms of cost-effectiveness, safety, and cosmetic and psychological outcomes.
