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.

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.

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.

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.

거버넌스이론의 이데올로기성 비판

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

폐Al dust와 폐주물사를 이용한 재료 개발

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.

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.

The purpose of this study is to investigate the difference in mental health between female dancing-majors and other majors in order to recognize the value of it and to provide necessary basic data to popularize dancing. SCR-90-R was used for investigating the mental health. The results are follows : dancing-majors had significantly low response(It means that this group is mentally healthy) to somatization, depression anxiety, phobic anxiety, paranoid ideation and psychiticism. However there is no significant difference in obsessive-compulsive behaviors, interpersonal sensitivity and hostility.

본 연구는 레진 블록에서 엔진구동형 Ni-Ti 기구를 이용하여 근관성형 후 Buchanan plugger의 삽입 깊이에 대한 비교를 통해 임상적 상황에서 Ni-Ti 파일로 근관 성형 후 Continuous wave of condensation technique을 이용한 근관 충전시 적절한 크기의 Buchanan plugger 선택에 지침을 제공하기 위해 시행되었다. 만곡근관과 직선근관을 가진 레진 블록에서 ProTaper와 ProFile을 이용하여 근관 성형을 하였다. 성형 후 근관에 Buchanan plugger 가 근관벽과 처음으로 접촉하는 부위까지 삽입한 후 그 상태에서 스태너를 이용하여 이미지를 얻었다. 이미지 분석 프로그램을 이용해 근첨에서 plugger 첨부까지의 거리를 얻었다. 각 기구에 대한 plugger 삽입깊이에 대한 유의성을 검정하기 위해 one-way ANOVA를 시행하였고, 사후검정을 위해 Scheffe's test를 시행하였다. 본 연구의 결과 만곡되고 좁읍 근관에서, ProTaper F2와 F3로 마무리 성형한 근관에서 F. FM 크기의 plugger를 사용할 경우 Continuous wave of condensation technique으로 적절한 근관충전이 가능함을 시사하였다. This study was conducted to evaluate the insertion depth of Buchanan plugger after shaping by various Ni-Ti rotary files. It was conducted to determine which size of plugger are appropriate, when root canals are shaped with Ni-Ti rotary files and obturated by Continuous wave of condensation technique. Two type of eighty simulated resin blocks were used : J-shaped and straight shaped canal. The simulated canals were instrumented by ProTaper and ProFile. Buchanan pluggers were inserted into the canal, and then the image was recorded to scanner. The distance from the apex of the canal to the plugger tip was measured by image analysis program. Data were analyzed by one-way ANOVA followed by Scheffe's test. The results were as follows 1. In straight canal finished up to ProTaper F2 and F3 file, F and FM pluggers were inserted more than 5 ㎜ short of working length. 2. In J-shaped canal finished up to ProTaper F2 file, F pluggers were inserted more than 5 ㎜ short of working length. Finished up to ProTaper F3 file, F and FM pluggers were inserted more than 5 ㎜ short of working length. 3. In straight and J-shaped canal finished up to ProFile . 06/#20 and ,06/#25, any of Buchanan plugger could not be inserted more than 5 ㎜ short of working lenghth. These results suggest that canals shaped by ProTaper could be obturated by Continuous wave of condensation technique with F and FM size Buchanan plugger.
