The purpose of this study is to analyze the contents and assessment items in the certification criteria for Child Care Support Apartment program in Japan that is implemented mainly by local authorities with a view to provide information that could be used as reference in enhancement of the residential environment. For this purpose, the architectural planning elements for individual residence units and the public spaces of the Child Care Support Apartment Certification programs in effect in Yokohama city were identified and analyzed. In spite of the recent trends in Korea, in which the residential services are more diversified and segmented in consideration of the needs of the residents and the increased interest in child care in general, the literatures that addressed the direct relationship between childbirth and residences are scarce, and it is anticipated that the result of this study would be of contribution to provide a hint in direction for improvement of residential environment with child support programs.

This study evaluated the antioxidant activity and quality characteristics of rice cookie with added butterbur powder in a ratio of 0, 5, 10, 15, and 20% to confirm the possibility of butterbur as a functional food. The moisture content, spread factor, leavening rate, and hardness of rice cookies increased with an increase in the amount of butterbur powder; whereas a decrease in the pH and baking loss rate was observed. The L and b values decreased as the amount of butterbur powder increased, but the value was the lowest when 5% of butterbur powder was added. The sensory liking score showed the highest preference for 10% butterbur powder regarding appearance, flavor, taste, texture, and overall preference. In the principal component analysis (PCA), the addition of 10% butterbur powder positively affected the measure of food acceptance in terms of organoleptic properties of butterbur. Besides, as the amount of added butterbur powder increased, the antioxidant activity of rice cookies increased. Based on these results, it appears that the addition of butterbur powder to rice cookies in a 10% ratio can produce rice cookies with excellent antioxidant activity, overall quality, and high preference.

The purpose of this study was to compare the postoperative stability and relapse according to 2 different fixation methods after bilateral sagittal split ramus osteotomies in mandibular prognathic patients. Tweenty one patients with Class III dental and skeletal malocclusion who were treated with bilateral sagittal split ramus osteotomy were selected for this retrospective study. We classfied the patients into two groups according to the fixation methods of bony segments after osteotomies. Group W (n = 10) had the bone segments fixed with nonrigid wire and Group S (n = 11) had bicortical screws inserted in the gonial area through a transcutaneous approach. Cephalometric radiographs were taken preoperatively, immediate postoperatively and more than six months postoperatively in each patient. After tracing the cephalometric radiographs, various parameters were measured. Before surgery, both groups were balanced with respect to linear and angular measurements of craniofacial morphology. Mean posterior sagittal setback amounts of the mandibular symphysis was 8.6 mm in the wire group and 6.79 mm in the rigid group, Six months postoperatively, the wire group had 33.1% relapse of the mandibular symphysis and 22.8% in the rigid group relapse. Both groups experienced changes in the orientation and configuration of the mandible. It is thought that Rigid screw fixation is a more stable method than nonrigid wire fixation for maintaining mandibular setback after sagittal split ramus osteotomy.

최희원,김경원,이은영,강지연,Choi, Hee-Won,Kim, Kyoung-Won,Lee, Eun-Young,Kang, Ji-Yeon 대한악안면성형재건외과학회 2006 Maxillofacial Plastic Reconstructive Surgery Vol.28 No.2

Pulmonary edema is a well known phenomenon in medicine, physical findings indicative of this condition include frothy pink sputum, dispnea, and chest X-ray may present cephalization of vessels, perihilar edema, or diffused increase of density. It is one of the most serious, life threatening situation and should be diagnosed and managed instantly. Early diagnosis and intensive treatment are mandatory in order to effectively resolve the situation. The most common etiology for this pathology is cardiogenic, such as left ventricular failure and valvular disease. The one following is noncardiogenic, such as transfusion, infectious pneumonia, inhaled toxins, shock lung in association with trauma. Other forms of pulmonary edema which have not been clearly explained result from pulmonary embolism, drug overdose, after anesthesia, epinephrine overdose, exposure to high altitude, neurogenic, etc. We experienced two cases of pulmonary edema during two jaw surgeries(Le Fort I Osteotomy & BSSRO). These patients were young and physically healthy individuals on preoperative evaluation. Thus we report and discuss the etiology, diagnosis, prognosis, and treatment with journals review. 폐부종은 구강악안면외과 영역의 수술 도중에 발생할 가능성이 있다. 따라서 전신마취하에 수술중인 외과의와 마취의는 환자의 상태를 주의깊게 관찰하여야 하며 수술 중 폐부종이 발생할 가능성에 항상 대비하여야 한다. 폐부종 증세가 발견되는 즉시, 즉각적이고도 적절한 처치를 시행한 경우 예후가 좋으며, 근본적인 원인치료 및 타장기의 합병증 및 후유증에 대하여 검사가 필요하다.

본 연구의 목적은 제 IV형 근관에서 Continuous Wave 가압법을 이용하여 충전할 때 System B Plugger tip의 깊이에 따른 근단부 밀폐효과를 평가하기 위함이다. 50개의 J형 만곡을 갖는 레진 블록에 부러진 F3 ProTaper 파일을 이용해 근관장에서 3mm 지점에 ledge를 형성한 후, F1 ProTaper Ni-Ti file을 이용해 레진 블록을 천공시켜 제 IV형 근관을 형성하고 System B Plugger tip의 깊이에 따라 3개의 실험군과 1개의 대조군으로 분류하였다. 제 IV형 근관의 거터퍼쳐와 실러의 길이는 확대경하에서 캘리퍼를 이용해 측정하였고 다음과 같은 결과를 얻었다. 1. 대조군의 설측 근관에서 거터퍼쳐와 실러 모두 관찰되지 않았다. 2. 3 mm군에서는 5 mm 또는 7 mm군에 비해 유의하게 많은 거터퍼쳐의 충전이 관찰되었다 (p<0.05). 3. 7 mm군에서는 유의하게 많은 빈 공간이 관찰되었다 (p<0.05). The purpose of this study was to evaluate the effect of the apical sealing according to the depth of the System B Plugger tip when root canal was filled with gutta-percha and sealer by Continuous Wave of Condensation technique in the Type IV canal. 50 simulated resin blocks with J-shaped curvature canals were instrumented by ProTaper (Dentsply Maillefer, Ballagiues, Switzerland) Ni-Ti files using the crown-down technique. Type IV canals were made using a broken ProTaper F3 Ni-Ti file for making a ledge at 3mm short from the working length. And ProTaper F1 Ni-Ti file was used for perforating resin block. The prepared Type IV canals were randomly divided into three experimental groups of 15 each according to the depth of System B Plugger tip. All of experimental groups were obturated with Continuous Wave of Condensation technique. The length of gutta-percha and sealer in lingual of the Type IV canals was measured with a measuring digital calliper under magnifying glass (${\times}2.3$). The results are as follows : 1. In control group, there was no gutta-percha and sealer in lingual canal. 2. 3 mm group showed relatively more gutta-percha than 5mm or 7 mm group (p<0.05). 3. 7 mm group did not showed gutta-percha and relatively more void were observed than 3mm or 5 mm group. (p<0.05) In conclusion, within the limits of the results of this experiment, the 3 mm depth of System B Plugger tip was acceptable for obturating the Type IV canal.

사용자 경험 디자인 방법론에 근거한 아파트단지 내 어린이놀이터 개선방안에 관한 다학제적 연구

최희원(Choi, Hee Won) 한국전시산업융합연구원 2018 한국과학예술융합학회 Vol.33 No.-

본 연구는 현재 국내의 대표적인 주거유형으로 자리 잡고 있는 아파트 단지 내에 설치된 어린이놀이터 디자인 시 사용자 고려가 미흡하다는 문제의식에서 출발하였다. 아파트 놀이터를 대상으로 사용자 경험디자인 수법을 적용하여 사례분석하고 그 결과를 바탕으로 개선점을 제시하며 향후 아파트 단지 놀이터 및 놀이시설 계획에 기초자료를 제시한다는 목적으로 진행하였다. 연구방법과 결과는 다음과 같다. 먼저 문헌연구를 통해 아파트 단지 내 어린이 놀이터, 사용자 경험 디자인 방법과 페르소나에 관한 내용을 고찰하였다. 그리고 인터넷과 문헌검색을 통해 세대 수, 소득수준, 준공시기, 소재지가 유사한 두 단지를 선정하여 놀이터 환경요소와 현황, 주요 사용자를 파악하였다. 이를 바탕으로 본 연구의 페르소나를 의사표현이 가능한 유아, 초등학생, 유아를 동반한 여성, 유아를 동반한 노인의 네 가지로 설정한 후, 각 페르소나 별로 인적사항 및 개인특성, 놀이터에서의 경험요소, 요구사항을 기술하고, 그 내용을 종합하여 개선방안을 도출하고자 하였다. 본 연구를 통해 도출한 결론은 다음과 같다. 첫째, 공급자 위주의 놀이터 및 놀이시설 배치의 경향에서 벗어나 사용자의 행태와 니즈가 고려된 놀이터 계획이 필요하다. 둘째, 주 사용자인 어린이의 경우 상상력과 창의력을 발휘할 수 있도록 더욱 다양한 놀이시설이 갖추어져야 하고, 낙상 등의 안전사고가 발생하지 않도록 연령별로 영역을 분리하는 등의 계획적 접근이 필요하다. 셋째, 어린이 뿐 아니라 다양한 유형의 보호자의 특성을 고려하여야 한다. 벤치와 그늘, 화장실,음수대, 간단한 수도시설, 유모차 보관 공간 등이 설치되면 더욱 편리하게 놀이터를 이용할 수 있을 것이므로, 보호자의 이용행태와 요구사항을 파악하는 작업이 선행되어야 할 것으로 사료된다. 본 연구는 ‘놀이터’라는 물리적 환경의 가장 중요한 요소는 ‘사용자’라는 점에 착안하여, 사용자 경험 디자인 방법론 중 페르소나 기법을 적용한 다학제적 연구라는 의의를 지닌다. 이를 통해 사용자가 더욱 중요시되는 아파트 놀이터 계획의 방향을 제시하고자 하였다. 향후 후속 연구에서는 폭넓고 객관적인 페르소나를 설정하고, 다양한 융 · 복합적 연구방법을 적용함으로써, 사용자의 입장과 요구사항이 충분히 반영된 아파트 놀이터 계획의 참고자료로 활용되기를 기대한다. This study started from the awareness of a problem that consideration of users is insufficient when making a design of children’s playground installed in an apartment complex, which is getting established as a representative housing type in Korea at present. To this end, this study conducted research with the intention of presenting improvement points on the basis of the case analysis result through the application of user experience design technique targeting the playground in an apartment complex, and also presenting basic data on apartment-complex playground & playing facilities planning for the time to come. The research method and results are as follows: First, through literature research, this study considered the contents on a children’s playground in the premises of an apartment complex, user experience design method and a persona. In addition, this study grasped playground environmental elements & status and major users by selecting two apartment complexes, whose number of households, income level, completion period, location were similar through bibliographic search. On the basis of this, this study set up the personae of this research as four sorts like an infant available for communication, elementary school student, woman accompanied by an infant, and senior citizen accompanied by an infant, and then, this study intended to deduct an improvement plan by describing personal information & personal traits by persona, experience elements at a playground, and requirements, and putting together general contents. The conclusion deducted through this research is as follows: First, it’s necessary to do playground planning in the light of user behavior & needs away from the tendency for a supplier-oriented positioning of playgrounds and playing facilities. Second, it is necessary that more diverse playing facilities should be equipped so that children as a main user can display imagination and creativity;further, required is a planned approach like separation of areas by age lest there should be a safety accident such as a hurt from a fall, etc. Third, it is definitely necessary to take account of not only children but also the traits of guardians of diverse types. Installation of benches, shade, toilet, drinking fountain, simplified water service, and stroller storage space, etc. will make it possible for users to more conveniently use a playground;in this context, it is thought that the work on grasping a guardian’s use behavior & requirements should be preceded. With the perception that the most vital element in physical environment of a ‘playground’ is the very ‘user’, this study has the significance in that it is a multidisciplinary research through the application of the persona technique among the user experience design methodologies. Through this process, this study intended to present the direction of apartment-complex playground planning, in which a user is considered more important. This study hopes that this research result could be used as reference data on apartment-complex playground planning, in which a user position & requirements are adequately reflected, by setting an extensive, objective persona applying diverse convergence research methods in the future follow-up researches.
