15Recombinant baculoviruses containing two alternative splice forms of the Drosophila Rdl GABA receptor gene were constructed. Spodoptera frugiperda (Sf21) cells infected with either splice form expressed a transcript of expected size (2.5 kb). Western blotting of cell membrane extracts and immunoprecipitation experiments with an anti-Rdl antiserum recognized a protein of the expected size of approximately 65 kDa. Whole cell patch clamp analysis of cells infected with either splice form revealed f
This technical procedure demonstrates a 4-step completely digital workflow for the fabrication of complete dentures in edentulous patients. The digital scan data of the edentulous arches were obtained using an intraoral scanner, followed by the fabrication of modeless trial denture bases using additive manufacturing. Using the trial denture base and a wax rim assembly, the interarch relationship was recorded. This record was digitized using an intraoral scanner and reversed for each maxillary an
Clinicians and researchers have used various methods to reproduce the maxillomandibular relationship and mandibular movement of individual patients using an articulator, with efforts being made to reduce errors associated with the conventional technique. When a change to a vertical dimension is required during the conventional prosthesis construction process, the maxillary and mandibular casts are mounted on the mechanical articulator using a facebow and bite registration and the elevation of th
Purpose: This study tested the effects of Nei-Guan acupressure on nausea, vomiting, and anorexia of lung cancer patients on chemotherapy. Methods: A nonequivalent control group pre-post test design was used to identify the effect of Nei-Guan acupressure on nausea, vomiting, and anorexia of lung cancer patients on chemotherapy. The participants were 60 patients who were admitted to a hospital for chemotherapy from February 1 to October 28, 2009. The patients were randomly assigned to the control
최근 종단자료 분석방법으로 많이 연구되는 잠재성장모형으로 청소년 패널자료를 분석하였다. 본 연구에서 잠재성장모형 분석에서 비조건적 모형을 좀 더 빠르게 찾기 위해 비조건적 모형에 반복측정 분산분석의 결과를 활용하였다. 또한, 비조건적 모형을 결정하기 위해 기존에 주로 사용된 6개 유형, 2차모형과 반복측정분산분석의 결과를 적용한 모형들을 비교하였다. We analyzed the data from KYPS using the latent growth model which has been widely studied as an analysis method of longitudinal data. In this study, we applied repeated measures ANOVA to unconditional model in order for faster decision of the unconditional model of the latent growth model. Also, we co
이 연구는 재한일본인의 문화적응 모형을 개발하고 설문조사를 통하여 문화적응 유형의 도출과 다문화 적 수용태도를 고찰하는데 있다. 연구결과 재한일본인들은 베리(Berry, 1997)의 문화적응 유형 중 제3유형, 즉 동화유형으로 개인이 한 국사회와의 관계를 긴밀히 유지하지만 일본의 문화적 정체성과 특성을 포기하는 유형, 제4유형, 즉 통합유 형으로 한국사회와의 관계를 유지하면서 동시에 일본문화의 문화적 정체성과 특성을 유지하는 문화적응 유형이 높게 나타났다. 이러한 결과는 재한일본인들이 한국사회에 문화적응도가 매우 높은 것으로 추정할 수 있지만 한편으로는 한국 문화적응에 대한 스트레스도 높은 것으로 짐작할 수 있다. 왜냐하면 반일감정이 강한 한국에서 재한일본인들이 생존하기 위해 전략적으로 선택한 동화와 통합의 문화적응 유형은 반대로 150만 명에 육박하는 외국인들에게 다양화된 한국사회를 보여주고 있지 않다는 연구결과를 의미하기 때문 이다. 이 연구는 재한일본인의 문화적응과 수용태도가
Background: With the advancement of digital technology, it has become possible to record jaw motion using intraoral scanners. However, there is a paucity of studies evaluating their accuracy. Methods: Twelve sets of scan data from 12 individuals were additively manufactured using a 3D printer and 3D-printable material. Each pair of scan data was mounted onto a semi-adjustable articulator. A blue articulating paper was inserted between the mounted models, and the pin of the articulator was moved
To provide services with a concept of anywhere, anytime, anyone, anything, and any device, ubiquitous and pervasive computing (UPC) becomes a popular paradigm. The purpose of UPC is to emerge computers into the real world to serve humans and the underneath infrastructure of UPC is called ubiquitous networks. In order to provide ubiquitous services (u-Service) which deliver useful information to service users without human intervention, this paper implements a proactive information delivery syste
설문조사에서는 대부분 단위무응답 또는 항목무응답이 발생한다. 무응답 발생비율이 높은 경우 무응답을 무시한 분석은 잘못된 결과를 초래할 수도 있으므로 무응답에 대한 특성 파악도 필요하다. 횡단자료에서는 항목무응답 특성에 대한 연구는 가능하나 단위무응답의 특성을 파악하기가 어렵다. 단위무응답의 특성을 파악하기 위하여 본 논문에서는 종단자료인 한국아동 청소년패널조사 중 중1패널자료를 이용하였다. 최근까지 공개된 한국아동 청소년패널조사자료를 이용한 논문들의 무응답 처리 실태를 파악하고, 그 중 단위무응답의 특성에 대하여 분석하였다. 이 자료를 이용한 논문에서는 대부분 단위무응답의 처리를 제거하는 방식을 취하고 있으며, 이 자료에서 제공하고 있는 가중치를 이용한 논문은 거의 없었다. 이에 단위무응답의 처리방법 중 가중치를 이용한 방법과 그 대상을 제외하는 두 가지 방법에 대해 여러 가지 특성들의 분석을 비교하였다. 많은 항목에서 두 가지 방법의 결과가 상이하게 나타났으며, 가중치를 이용한 경
An understanding of occlusion is essential to examine and recover the patient's overall oral condition. In order to understand academics in occlusion, it is necessary to look into its history. In the 1850s, most prosthetic treatment meant restoration of complete dentures, so many scholars suggested balanced occlusion to enhance the stability of dentures. Since the restoration of natural teeth using the casting became possible after the 1920s, a long history of debate represented by Gnathology an
