梁海承,韓五炯 조선대학교 기초과학연구소 1986 自然科學硏究 Vol.9 No.1

In the flotation of sulfide ores, Xanthates are most commonly used to prepare the surface of the mineral to be floated so that attachment air takes place. The amount of xanthate adsorbed was determined from the decrease in xanthate concentration in the solution during the test. Important results are follows; 1) The adsorption of xanthate shows that it has maximum absorption peak at a concentration of 20㎎/ℓ. 2) Necessary amount of copper sulphate as a activator is about 1X10^-3 mol/ℓ. 3) The adsorption of xanthate of sphalerite decreased in accordance with the increase of pH. 4) Effect of temperature of tile solution on adsorption of ethyl xanthate is increased with the temperature of the solution.

梁海承 조선대학교 동력자원연구소 1996 動力資源硏究所誌 Vol.18 No.1

This research is to check the results of intake air quantity, outlet air quantity and the temperature of pits which are operating in first, second and third incline of Dong Gan(eastern pit) in Whasoon coal mine. The total intake air volume and it outlet volume measured in this pit was 2.319㎥/min and 2.419㎥/min, respectively. The average operating temperature of this mine was 28℃. The ventilation quantity based upon the required volume of ventilation and temperature was 6.6㎥/min per man by thedretical calculation method and on the other hand, the ventilatin quantity based on the pit temperature was calculated as 642㎥/min. These results means that this mine is properly operating according to the mine safy regulations.

和順炭鑛의 抗內通氣와 溫度 測定

梁海承 조선대학교 기초과학연구소 1988 自然科學硏究 Vol.11 No.1

This study aimed to investigated the temperature and the air ventilation guantity of tunnel which has deepened owing to the increasing coal development. In this experiment, the air ventilation quantity was analysed, and air velocity was measured by the digital rotameter and Taylor anemometer and its result was averaged. The value of ventilation resistance was evaluated by the measurement of pressure difference and showed in the Table 1. And the columnar mercury thermometer was used as the measurement of the temperature of tunnel, in every 50m intervals. The result showed that it was 25℃ in maximum but much less than the value of Korean mine safety regulation.

梁海承 조선대학교 생산기술연구소 1979 生産技術硏究 Vol.1979 No.-

Dado-pyrophyllite, tremolitc talc and blast furnace slag have been used to develop a refractory material to the simple firing process. Some of physical properties of the raw materials were investigated. Thereafter the effects of feed ratios of pyroplyllite, blast furnace slag and talc on the physical and thermal properties, such as porosity, water absorption, specific gravity, compressive strength and resistance to corrosion were tested.

중국 내 ‘한국어 강독 수업’에 언어 중심의 문화교수법의적용 연구 : 4년제 대학을 중심으로

양해승 서울대학교 언어교육원 2015 語學硏究 Vol.51 No.1

This paper mainly adopted Language-Based Culture Teaching approach, combined with many other teaching approaches to explore and study in depth college Korean intensive reading course’s teaching model in China. To this end, this paper is mainly divided into two parts. First, this paper takes a fresh look at previous scholars’ opinions about the definition of Korean intensive reading course. Based on the discussion on the goal of talent cultivation on minor languages major which is promulgated by China’s ministry of education and college Korean intensive reading course’s importance, nature and status, this paper redefined the college Korean intensive reading course and came to the conclusion that the college Korean intensive reading course should be aimed at raising students’ capability of the following five categories: Basic Korean language knowledge, Korean language skills on listening, speaking, reading, writing, and translating, Korean communication and interpersonal ability, Understanding of varieties of Korean culture, Korean Studies’ research ability. Secondly, this paper divided college Korean intensive reading course into pronunciation course and dialogue- text course, mainly adopting Language-Based Culture Teaching approach, combined with many other teaching approaches to build a new college Korean intensive reading course’s teaching model in China.

和順炭鑛 挾石混合 賦存區域 의 中段採炭法 應用에 對하여

In Dong-Mine of Hwasooon Coal mines, considerable amount of roks are developed within coal seams by repeated folding with reional metamorophism in sandstone seams. Such condition prevents mechanization of mining operations which has been exercised. Therefore, in this study, sub-level mining method is adapted for rook raise connects the upper and lower level with 45? inclination and sub-level is installed in the middle of blocks every 10M distances. And mono-rail or coolie car was installed for the materials. Another chute was driven for the coal and waste. Such system was maintained from January to October, 1987 with favorable results. The annual deepening ratio was reduced to 4M/Year, the recovery increased 40%, accident rate reduced to 79%, and OMS was increased 30%. Adaptation of sub-level coal mining method for the seams with rooks are developed in Hwasoon Coal Mines.

國內産 粘土의 界面荷電性에 對한 硏究

梁海承 조선대학교 동력자원연구소 1980 動力資源硏究所誌 Vol.2 No.1

Three clay types of korean clays were chosen for comparative purposes in surface char-acteristics. The electrophoretic mobility and setting velocity of each clay sample was measured with its suspension. The isoelectric point of the kaolinite type clay was found in the strong acidic region, but other clays showed themselves always charged negatively and of high zeta potential.

소프트웨어 개발비용의 증대로 레거시시스템을 재사용하기 위한 방안과 이를 지원하기 위한 자동화 도구에 관한 관심이 고조되고 있다. 따라서, 본 논문에서는 레거시시스템에 대한 정의와 개념 나아가 등장 배경을 실질적인 시장과 공급사와 기술적 동향을 통해 이를 밝히고 있으며, 레거시시스템을 처리하는 구체적인 개발절차 그리고 구축사례, 평가기준과 이를 효율적으로 처리하기 위한 자동화 도구를 설계하고 개발하였다. 또한, 본 논문에서 제시하는 LM(Legacy to Modern System) 지원도구를 활용하여 레거시 시스템을 분석하고 후보 컴퍼넌트를 추출하여 정제한 다음 저장하여 재사용하는 과정을 구현하였다. 본 LM지원도구를 레거시 시스템의 마이그레이션에 적용할 경우 소프트웨어 재사용의 효과를 통해 비용절감, 개발기간 단축 나아가 기존의 지적재산을 승계하는 효과를 기대할 수 있다. Due to increased software development cost, interest about the method and automated tool for reusing legacy system have been running high. Therefore, In this study, it proves the definition, concept and also background of legacy system by showing real market and technology trend. Automation tool is designed and developed to handle the concrete development methodology, procedure and reference. Also, we implemented the process that analyze the legacy system and extract, refine, store and reuse the candidate components by using LM(Legacy to Modern System) supporting tool presented in this paper. If LM supporting tool is applied to legacy system migration, we can expect cutting costs, shortening the developing period and succeeding the intellectual property by software re-engineering.
