Airspeed and altimeter calibration of "win Mee was conducted by the flight test. We have adopted system to system method. Flight test data is corrected for instrumented error and position error, and the resultin data was satisfied. Climb Performance flight test also was conducted. But we could not have all data because of limited flight time. The resulted data was satisfied compare with calculated dab.

黃龍吉,金蓮洙,金宰逸 동아대학교 환경문제연구소 1986 硏究報告 Vol.19 No.2

The results of sulphuric acid leaching Aluminium dust and of making hydraulic-setting cement stone using Aluminium dust are as follows. 1. Sulphuric acid leaching efficient of Al is better when concentration of sulphuric acid is 200gr/ℓ, over 60℃, for lhours. 2. The aqueous solution recovered from sulphuric acid leaching of Aluminium dust contains Al^(+3) 13.5gr/ℓ and Fe^(2+) 1.65g/ℓ. 3. The hydraulic-setting cement stone making from mixture of cement, foundry sand, fly ash and Aluminium dust pulp(Na₂O·Al₂O₃) has more compressive strength comparing to other cement stones which make from mixture of cement, foundry sand and Aluminium dust pulp and mixture of cement and sand only. 4. Aluminium dust pulp has rapid hydraulic-setting effect in making cement stone.

The present study was carried out to investigate the potential acute toxicity of safflower seed by a single oral dose in ICR mice. Twenty animals of each sex were randomly assigned to four groups of 5 rats each and were administered singly by gavage at dose levels of 0, and 2,500 mg/kg bodyweight. Mortalities, clinical findings, and body weight changes were found and complete gross postmortem examinations were performed. Throughout the study period, no treatment-related deaths were observed. There were no adverse effects in clinical signs, body weight, and gross findings at any dose tested. The results showed that the single oral administration of safflower seed did not cause any toxic effect at the dose levels of 2,500 mg/kg in rats and the minimal lethal dose was considered to be over 2,500 mg/kg body weight for both sexes.

거버넌스이론의 이데올로기성 비판

윤정길,강황선 건국대학교 사회과학연구소 2001 社會科學論叢 Vol.25 No.-

Governance is a widely supported and accepted concept in the political and administrative system of the world. It refers to a managerial mechanism and also a philosophy in those arenas. This article goes over the concept theoretically in a holistic perspective in order to explore its fundamental principles. This article pinpoints the deterministic nature of the concept. Since the concept was born and developed by other western and developed countries, it may be inevitable that the concept has been well geared to those countries. This article argues that any countries and governments should be able to discern their own not only peculiarities of political and administrative system, but also those of civil society and its capacity to deal with public affairs as a partner of governments. Many influential studies on governance are discussed and analyzed so as to highlight its relativity. The authors explain main activities, coordinators between various stakeholders, and the role of stakeholders in governance system and emphasize the relative nature of the interface between stakeholders of governance system. This article tries to contribute to more stable adaptation of the theory of governance in Korea

The corrected transposition of the great arteries is a rare congenital heart anomaly consisting of the discordant connections of both the atria to ventricles and the ventricles to the great arteries. But its circulation is physiologically corrected and therefore it is compatible with life unless there are associated lesions. Our case was associated with VSD, COA, and PDA. He was slightly cyanotic and irritable. Despite of oxygen supply, his symptoms were not improved and he eventually died in 52 hours after delivery. Medical record revealed severe respiratory and metabolic acidosis.

This study was performed to evaluation the skin and eye irritation of etofenprox 8% and spinosad 4% combination in male New Zealand White rabbits. In skin irritation test, the combination of etofenprox and spinosad did not showed any change of body weight but caused slight skin irritation with the P.I.I. (primary irritation index) value 0.25. The etofenprox and spinosad combination showed severe eye irritation 1 h, 24 h, 48 h, and 72 h after ocular treatment, having the A.O.I. (acute ocular irritation) value of 37.3. Therefore, these result indicated that the combination of etofenprox and spinosad might be irritant formulation on eye and skin.

現代會計思想의 革命的 趨勢에 관한 一考

黃潤植 울산과학대학 1979 연구논문집 Vol.4 No.2

本稿의 主題는 오늘날 會計理論家(그리고 實務家中 보다 思考的인 者)들이 會計를 하나의 知的인 學科로서 그리고 應用社會科學의 하나로서 보는 方向과, 財務的 測定과 報告의 技法을 改善하기 위하여 確實한 基礎로서 會計의 理論的 構造에 대하여 보다 높은 凝集性과 首尾一貫性을 賦與시키고 있는 努力들을 分析·吟味하는 것이다. The principal subjects of this paper are the way in which present-day academic accountants(and the more thoughtful members of the profession on its commercial and practising sides) regard accounting as an intellectual discipline, and as one of the applied social sciences, and the endeavours which have been and are being made to give its theoretical structures greater coherence and consistency, as sure foundations for improved techniques of financial measurement and reporting.

안정골구조물 중첩법(stable structural superimposition method)을 사용해야 하는 합리적 근거 및 그 중첩방법의 소개

전윤식,황충주 대한치과교정학회 1997 대한치과교정학회지 Vol.27 No.5

Bjork와 Skieller는 상, 하악골에 임플란트를 매식하여 안면골 성장유형을 관찰한 결과 성장으로 인하여 영향을 받지 않는 안정된 골구조물(stable structure)의 존재를 확인했고 성장중에 있는 환자의 안면골을 중첩할 때에는 반드시 이러한 부위를 기준으로 중첩해야 한다고 하였다. 그럼에도 불구하고 40여년이 흐른 지금까지 대부분의 교정의들은 안정골구조물을 이용한 중첩법(structural method)보다는 최적중첩법(best fit method)을 선호하고 있다. 그러나 Angle씨 부정교합 Ⅱ급 2류의 하악골과 같이 특징적으로 전상방 성장을 하는 골격구조를 갖는 증례와, 치료후 장기관찰 증례에서는 두 중첩법 사이에 현저한 차이가 있다는 사실을 부인할 수는 없다. 이제는 윤리적인 문제때문에 더이상 임플란트를 매식하여 관찰하여 연구를 할 수 없게 되어 Bjork가 연구해왔던 임플란트 자료를 근거로 안정골구조물 중첩법을 사용할 수 밖에 없다. 따라서 안정골구조물 중첩법의 실용화를 위하여 본 저자들은 안정골구조물 중첩법의 합리적 근거를 제시하고 중첩방법을 자세히 소개하고자 한다. Bjork and Skieller concluded after following facial growth patterns using implants in upper and lower jaw bones that stable structures, which are not influenced by the growth to exist and so these must be the reference landmarks in the process of superimposition. In spite of such facts, for the last 40 years since the discovery of stable structures, most orthodontists have preferred best fit superimposition method to structural method. Case such as Angle's Class Ⅱ division 2 malocclusion that show characteristic forward and upward growth or one under long period of post-treatment observation demonstrate that distinct differences exist between the two methods of superimposition. Today, ethical concerns prohibit further growth studies that use implants, and so there is no choice but to use stable structural superimposition method based on Bjork's data. Thus, to encourage clinical use of stable structural superimposition method, logic for the use of stable structural superimposition method will be demonstrated, and its technical methods of application will be introduced step by step.

The following study is to clarify the effects on the life satisfaction and the mental health of the participation or non-participation in bowling and the flow degree on it. and the purpose is to present the necessary theoretical foundations to activate bowling with the base on the actual data of social psychological value. The study targeted for the 126 housewife participants and 143 non-participants. a total of 269 people. We researched the flow degree in bowling base on the flow experience questionnaire of Omodei & Wearing(1990). the life satisfaction based on Life Satisfaction Index which Medley developed (1976) and the mental health based on Symptom, Check List-go Revision of Derogatis et al(1973) On the case of the participation or non-participation. the life satisfaction of the participants was higher than the non-participants as the result. There was no significant difference in the interpersonal sensitivity, hostility, phobic anxiety and psychiticism on the case of mental health However. the participants showed lower respond(it means they are healthful) than the non-participants significantly on the somatization. obsessive-compulsive, depression. anxiety and paranoid ideation. It was found that th higher flow degree. the superior life satisfaction and mental healthe in the bowling participant groups.
