A piezoelectric ultrasonic bone surgical instrument, usually used to remove the tartar out of teeth or to cut the dentine of the tooth, is a recently popular instrument for dental treatment due to its several merits such as small size, low-electric power and precision control of surgical operation. It has typically two parts of a tip and vibration system which is also composed of head, piezoelectric elements and tail-mass. In order to improve the performance of the instrument, it is important to standardize the size of the vibration system without tip for high performance. In this study, a Finite Element Analysis (FEA) was utilized to optimize the structure of ultrasonic instrument in vibration system. Consequently, this study revealed that influence of several tips on property were minimized and it showed good property at the frequency range of 22~32 kHz.

The osseointegration of dental implant is influenced by many factors such as surface geometry, loading and the amount of bone. Thus, stability of the dental implant should be checked periodically. In order to test the stability of dental implant by using resonance frequency analysis, we designed a structure of transducers and fabricated a piezoelectric devices. Using finite element analysis, the thickness and length of piezoelectric device and transducers were tailorized and the optimized frequency of 10 kHz was obtained. The resonance frequency from simulation analysis and evaluation was estimated to be similar as 10 kHz. The osseointegration was further enhanced with increasing frequency from the evaluation result of the finite element analysis.

이주희,윤용갑,Lee, Ju-Hee,Yun, Young-Gab 대한한의학방제학회 2010 大韓韓醫學方劑學會誌 Vol.18 No.1

From the Herbal Prescriptional Study of Bangpungtongsungsan(防風通聖散, BPTS). It can be concluded as follows. 1. The origin of BPTS is the book of sunmyungronbang(宣明論方) in 1172. BPTS' hebal compositons are not changed in history, but it's doses had been changed. When BPTS are written to dongeuibogam(東醫寶鑑) in 1610, that's doses are added 0.75g to each herbs dose according to the korean people's constitution. 2. BPTS are composed of five elemental prescriptions. that are yugilsan(六一散), bakhotang(白虎湯), hoechunyanggyeoksan(回春凉膈散), jowiseunggitang(調胃承氣湯) and saengryosamultang(生料四物湯), and three subsidiary prescriptions and some herbs have collateral effects in BPTS. 3. BPTS can cure some diseases that are cause by fever with wind, heat in gastrointestinal tract, anemia after childbirth, heat that is caused by kidney's disease, hemorrhoids, alcoholic poisoning, contusion and constipation that are caused by intestinal heat. 4. BPTS can cure hypertension, hyperlipidemia and Obesity also.

There are various systems that allow humans to safely maintain their space exploration missions and lives in completely different environments, such as the International Space Station, the Moon (the closest celestial body to Earth), and Mars (the only planet in the solar system for manned mission in the 2030s). Among them, when it comes to maintaining the basic breathing of humans, the human life support air management system is a key device system. Such an air management system can be used not only for space exploration but also for undersea bases and submarines on Earth where humans reside. The air management system basically consists of an oxygen generation system, a carbon dioxide removal system, and a harmful substance removal system. In this paper, in order to develop an air management system that can be used in an underwater residential platform, the development requirements of a ground test module to be used as an experimental facility were analyzed.

본 연구는 1983년 설계공모 제도가 한국 조경계에 도입되고 30년이 지난 현 시점에서 조경 설계공모 과정에서 발생되고 있는 문제점을 분석 고찰함으로써 향후 조경 설계공모 과정 개선에 기여할 수 있는 기초자료를 제공하기 위한 목적으로 수행하였다. 연구를 수행하기 위해 조경 설계공모에 관여하는 전문가를 대상으로 델파이 조사를 실시하여 문제점을 도출하였으며, 그 결과는 다음과 같다. 첫째, 조경설계 공모 관련 이론과 선행연구를 분석한 결과, '설계공모 방식', '설계공모 지침', '당선작 선정과정', '당선작 이후 설계변화' 등 4가지 관점에서 문제점이 있는 것으로 나타났다. 둘째, 전문가 델파이 분석을 통하여 전문가들의 의견을 합의하는 과정을 이끌었고, 그 결과 총 12개의 항목으로 조경설계 공모 과정의 문제점이 도출되었는바, '설계공모 방식'에서는 '설계공모 기간의 문제', '설계공모 방식' 등 2가지의 항목, '설계공모 지침'에서는 '비위계적이고 혼란스러운 지침', '규정적으로 정해지는 지침', '지침의 분량의 과다' 등 3개 항목, '당선작 선정과정'에서는 '심사위원 전문성 결여', '비조경전문가 참여', '심사배점 방식에 문제점' 등 3개 항목, '당선작 이후 설계변화'에서는 '발주처 설계담당자의 잦은 인사이동', '설계기간의 기약 없는 과다연장', '발주처의견이 과다하게 반영되는 풍토', '원설계의 창의성을 저감시키는 발주처 의견' 등 4가지 항목이 문제점으로 나타났다. This study has been performed to analyze and consider the problems after 30 years in terms of landscape design competition process in Korea, so that it can provide the basic data, which can improve the future landscape design competition. We have used Delphi Investigation to carry out a survey that targets professionals and identifies problems. The results are summarized as follows. Firstly, the results of the analysis of Landscape Design Competition for institution theory and case studies showed that there is an issue from four perspectives which are 'method of design competition', 'guidelines for design competition', 'winner selection process', and 'design changes after winning' Secondly, the process by professional Delphi performed expert analysis, and agree with expert opinion. As a result, we derived the problems of a landscape design competition system with the 12 items. Third, in the 'design competition style', two items, the 'design competition style' and 'problem of design public offering period' had become a problem. Fourth, the 'Guidelines for design competition', 'non-hierarchical excess of the amount of instructions', 'directive determined the guidelines', and the 'provision of confusion' three items had also become a problem. Fifth, 'sex expert committee review selection process winning work', 'Problems of participation', 'examination scoring system experts lack', and 'non-landscaping' had become a problem. Sixth, 'The design of the original order' as much as possible 'design changes after the winning work' Four 'order to Comments to reduce the creativity of the design of the climate', 'original extension', 'contractor feedback of excess without the promise of frequent personnel changes', design period of the person in charge is reflected in excess item has become a problem. I considered that a continuous research on the improvement of the problems of the landscape design competition system based on the results must be performed.

Background: Idiopathic interstitial pneumonia (IIP), which has autoimmune features but do not fulfill criteria for a specific connective tissue disease (CTD), was recently defined as interstitial pneumonia with autoimmune features (IPAF). However, clinical characteristics and prognosis of IPAF are not well defined. Methods: Clinical data were retrospectively analyzed in 491 IIP and 98 CTD-ILD patients diagnosed at Asan Medical Center from 2000 to 2007. Results: Median follow-up period was 105 months. Among IIP patients, 17.7% were classified as IPAF (9.5% in IPF, 45.9% in NSIP, 36.4% in COP, 17.1% in unclassifiable IIP). IPAF group had more female (56.3 vs. 26.7%), non-smoker (60.9 vs. 30.6%) and lesser UIP pattern (33.3 vs. 68.1%) compared to non-IPAF-IIP group (all, p<0.001). However, they showed older age (60.6 vs. 54.2 years) and lesser female (56.3 vs. 80.6%), non-smoker (60.9 vs. 79.6%) and UIP pattern (33.3 vs. 52.0%) compared to CTD-ILD group (all, p<0.05). During follow-up, CTDs developed more frequently (13.8 vs. 3.2%, p<0.001) in IPAF compared to non-IPAF-IIP. IPAF showed better prognosis (median survival, 116 vs. 84.5 months, p=0.004) than non-IPAF-IIP, however, was similar with CTD-ILD (117 months). IPAF with UIP pattern showed worse survival than those without (58 vs. 119 months, p<0.001). In IIP, IPAF was an independent prognostic factor (HR0.586, 95% CI0.409-0.840, p=0.004) with female sex, age, FVC and DLco. Conclusions: IPAF showed different clinical features with non-IPAF-IIP or CTD-ILD. Prognosis of IPAF was better than non-IPAF-IIP, similar to CTD-ILD.
