Background: The combination of spinal and epidural anesthesia provides an efficient and profound anesthesia for surgery. There are needle through needle technique (NTN) and double segmental technique (DST) for combined spinal and epidural anesthesia (CSE). Some reports have differences about both techniques. We compared both techniques. Method: 87 patients were randomized to receive CSE by NTN (n=43) or DST (n=44). We measured procedure time, the numbers of attempted epidural punctures, epidural catheterizations, spinal punctures, and changes of operators. And we investigated success of spinal block and complications (the number of migrations of epidural catheter tip, headache, lumbar backache, postoperative nausea and vomiting and inadvertant dura puncture) of both techniques. Results: The number of attempted spinal punctures in NTN group is 1.4±0.9, which is smaller than 1.8±1.4 in DST group, The others are no difference significantly in NTN and DST groups. Conclusion: We find NTN and DST for CSE are no differences significantly in the technical problems and complications. We suggest the choice of NTN or DST for CSE is dependent on the skillfullness by operator.

Combined application of roll flap and combination onlay-interpositional graft to enhance esthetics of maxillary anterior fixed partial denture: A case report

Sang-Chun Oh,Dong-Hee Cha,Jae-In Lee 대한치과보철학회 2016 The Journal of Advanced Prosthodontics Vol.8 No.1

In the maxillary anterior region, reconstruction of the localized alveolar ridge defect is very important in enhancing the esthetics of fixed partial denture. A 40-year-old female patient presented with a chief complaint of the inconvenience and unesthetic problem of 3-unit maxillary anterior prosthesis due to alveolar ridge resorption. After removal of old prosthesis, intraoral examination revealed moderate (buccolingually 4 mm) ridge deficiency in missing tooth region, leading to the diagnosis of Class I alveolar ridge defect. One of the reconstruction techniques to overcome this problem might be a technique that combines two types of soft tissue augmentation techniques. The purpose of this paper was to demonstrate the new combined technique of roll flap and combination onlay-interpositional graft utilized to acquire sufficient dimension of recipient area by one time of operation and to present the esthetic improvement of fixed partial denture by using this procedure in case of maxillary anterior localized ridge defect.

Purpose: The purpose of this study is to compare changes in the flexibility of hamstring muscles which are relaxed on suboccipital muscle through suboccipital muscle inhibition and combination technique. Methods: Thirty sample subjects (16 male and 14 female) were randomly divided into an experimental group (n=15) and a control group (n=15). 1. Suboccipital muscle inhibition: Suboccipital muscles of the patients were placed on a bed. The occipital region was placed on a therapist's fingers, and the posture was maintained for three minutes before remeasurement. 2. Treatment with combination technique (body bolster and wooden pillow): Wooden pillows were placed where the participants could relax the posterior arch of the atlas; additional body bolsters were also placed to avoid high pressure, and the treatment was maintained for three minutes before remeasurement. Results: There was a statistical difference in finger floor distance (FFD) and straight leg raise (SLR) results for those treated with SMI (P<0.05). There was no statistical difference in FFD and SLR results for those treated with the combination technique (P>0.05). Conclusion: Between the two intervention methods; the suboccipital muscle inhibition technique was more effective in increasing the flexibility of subjects with a shortened hamstring than was the combination technique.

표현의 확장으로서 도자 옻칠 수리연구

박 미란 한국도자학회 2023 한국도자학연구 Vol.20 No.1

ﾠHard porcelain made at a high temperature has a smooth and glossy surface. It is hygienic and easy to manage, but its physical properties make it vulnerable to shock, which means it has a disadvantage of being easily breakable. Once broken, porcelain loses its original functions. Damaged porcelain is generally discarded or undergoes a complex process of repair to be used again. Porcelain repair began with the need to repair and preserve antiques or cultural artifacts and has been expanded to personal works or cherished items. Repair of porcelain, however, requires mastery across broad areas from the knowledge of many different materials and careful processing skills to historical research. The repair process should find the most superior and appropriate material by combining reinforced and auxiliary materials and repeating experiments. These reasons mean that although the repair process goes through complicated stages and requires many hours, this repair and maintenance work itself holds important significance and value. This study examines the process of porcelain repair from its original purposes to the domain of expression with the advancement of facilities, including new glues, paint materials, and spray materials according to the development of porcelain repair techniques. Different techniques are used depending on the purpose, such as Kintsugi, Rivert, and weaving to intentionally break porcelain into pieces or combine porcelain fragments that are easily thrown away. The techniques used to restore the complete form of a vessel, in particular, have been broadly applied to contemporary ceramic expressions through the processes of intentional combination, rearrangement, and reediting as well as intuitive and spontaneous combination styles, reproducing a variety of metaphorical functions and meanings. 고온으로 소성된 경질 도자기는 매끄럽고 광택이 나는 표면을 띄게 되며 위생적이고 관리가 편리한 반면에 충격에 취약한 물리적 성질을 동시에 지니고 있어 쉽게 파손될 수 있는 단점도 지녔다. 도자기는 일단 깨져 버리면 본래의 기능을 상실하기 때문에 손상된 도자기는 일반적으로는 폐기되거나 수리하여 사용하기 위한 복잡한 과정을 밟게 된다. 도자기 수리는 골동품이나 문물의 보수 및 보존 작업의 필요에 따라 시작되었으며, 현재에는 개인 작품 혹은 애장품으로까지 확대되었다. 하지만 도자기 수리 작업에는 여러 가지 재료에 대한 지식과 세심한 처리 기술뿐만 아니라 역사적 고증까지의 폭넓은 부분의 숙달이 필요하다. 수리 과정에서는 보강재료와 보조재료 등을 조합해 반복적인 실험을 통해 가장 우수하고 적합한 재료를 찾아내야 한다. 이러한 이유로 수리 과정은 복잡한 단계와 긴 시간이 필요하나 수리, 보수작업은 그 자체로 중요한 의의와 가치를 지니고 있다. 본 논문에서는 도자기 수리 기술의 발전에 따라 새로운 접합제, 도색재료, 분사 재료 등의 설비가 진일보함에 따라 도자 수리는 본래의 목적으로부터 표현의 영역으로까지 확대되고 있는 과정을 살펴본다. 목적에 따라 의도적으로 조각을 내거나 버려지기 쉬운 도자 조각 파편을 의도적으로 결합하는 방식으로 킨츠키(kintsugi) 기법, 꿰매기(Rivert), 엮어내기 등의 사용되고 있다. 특히 완결된 기형(器形)을 복원하기 위해 사용되었던 기법들은 직관적이며 즉흥적인 결합 방식뿐만 아니라 의도적 결합, 재배열, 재편집 과정을 통해 현대 도예 표현에 폭넓게 적용되어 다양한 은유적 기능과 의미를 재생산하고 있다.

The research methods and improvement measures proposed in this study can be useful for designing and coordinating the curriculum in the military and improving the 「Combined Forces Education System」.

Type II combination questionnaire model: A new survey design for a totally sensitive binary variable correlated with another nonsensitive binary variable

Xifen Huang,Guo-Liang Tian,Yin Liu,Jun-Wu Yu 한국통계학회 2015 Journal of the Korean Statistical Society Vol.44 No.3

Recently, Yu, Lu, and Tian (2013) introduced a combination questionnaire model to investigate the association between one sensitive binary variable and another non-sensitive binary variable. However, in practice, we sometimes need to assess the association between one totally sensitive binary variable (e.g., the number of sex partners being 63 or >3, the annual income being 6$25,000 or >$25,000, and so on) and one non-sensitive binary variable (e.g., good or poor health status, with or without cervical cancer, and so on). Although we could directly adopt the four-category parallel model (Liu & Tian, 2013), the information contained in the non-sensitive binary variable cannot be utilized in the design. Intuitively, such information can be used to enhance the degree of privacy protection so that more respondents will not face the sensitive question. The objective of this paper is to propose a new survey design (called Type II combination questionnaire model, which consists of a four-category parallel questionnaire and a supplemental direct questionnaire) and to develop corresponding statistical methods for analyzing sensitive data collected by this technique. Likelihood-based methods including maximum likelihood estimates, asymptotic and bootstrap confidence intervals of parameters of interest are derived. A likelihood ratio test is provided to test the association between the two binary random variables. Bayesian methods are also presented. Simulation studies are performed and a cervical cancer data set in Atlanta is used to illustrate the proposed methods.
