『자본』체계 내 ‘도덕적 요소’의 역할 - 고정자본과 가변자본의 경우
김영용 한국사회경제학회 2024 사회경제평론 Vol.37 No.1
To describe the obsolescence of fixed capital and change of labor power value, Marx introduces the concept of ‘moral’ in Capital. This paper tries to investigate the theoretical role of the moral elements in the whole system of Marxian economics. Owing to technological progress and class struggles, capitalist mode of production becomes to be a kind of game which rules of reproduction should be ceaselessly altered. The permanent changes in production/consumption norms forces economic agents like, capitalists to adapt to everchanging standards. One can conjecture that Marx adopts the ‘moral’ concept to analyse this process.
버퍼를 가진 다중코드-코드분할다중접속(MC-CDMA) 시스템에서 동적 전송 제어 프로토콜 설계
김영용 대한전자공학회 2002 電子工學會論文誌-TC (Telecommunications) Vol.39 No.9
The demand for multimedia transmission in wireless networking is rapidly increasing. Performance evaluation in the CDMA system has been carried out on the voice-oriented system without re-transmission or buffering. We propose a multimedia access protocol with buffering and ARQ which can meet a variety of QoS requirements. We study the effect of buffering in MC-CDMA(Multi-Code CDMA) and design a dynamic rate control algorithms, whose simulation shows the efficiency of MC-CDMA. 무선 통신망에서의 멀티미디어 전송에 대한 요구는 빠른 속도로 증가하고 있다. 지금까지 CDMA에서의 시스템 분석은 패킷의 재전송을 위한 버퍼가 없는 음성을 위주로 이루어져 왔으나 본 논문에서는 버퍼링과 재전송을 고려한 다양한 QoS 요구조건을 만족할 수 있는 멀티미디어 접속 프로토콜을 제안하고 분석하였다. 먼저 다양한 전송률을 사용할 수 있는 MC-CDMA(Multi-Code CDMA) 전송방식 위에서 버퍼링의 영향을 살펴 보고 다양한 조건에서의 동적 전송률 제어 방식을 제안하고 시뮬레이션을 통해 제시한 방법의 타당성을 검증하였다.
遮光이 溫州蜜柑의 結實, 果實生長 및 品質에 미치는 影響

To determine the effects of shading on setting, growth and quality of satsuma mandarin (Citrus unshiu MARC.) fruits, 15-year-old trees were shaded with black cheese cloths for every ten days from June 10 to August 20 and every one month from August to September. The fruits shaded at stage of physiological fruit drop from June to July were significantly dropped, and fruit setting was on 0.5-1.6% with almost dropping of fruits shaded at the middle and last ten days of July. There was no severe fruit drop with shading in August, and no drops were observed on fruits shaded in September, October and November respectively. Fruit growth and pulp ratio were decreased by shading in August and September, There was an apparent decrease of fruit shape index by shading in September, but no differences in specific fruit gravity and rind thickness among shading treatment. There was highest chlorophyll content of fruit peel as related to less coloring in October. Soluble solids and solids/acid ratio of juice were remarkably decreased with shading in October and September, and acid content of juice was highest with shading in September. Therefore, shading in October went to the poor quality of satsuma mandarin fruits.

This survey study was carried out to find out the characteristics and current status of Cheju Teachers College students of 1987 academic year. The data were the freshmen, sophomore and junior responses obtained in the questionaire of 46 alternative issues. The results obtained were summarized as follows. The individual chaacteristics of students were showed that 51 per cent of them had no religiousness, 7.2 per cent had experience repeating a colloege entrance exam, and 96.6 per cent of their home town was Cheju district. As their home environmental conditions, 80.8 per cent of the students had both parents and 17.2 per cent had widow. The size of their family was six or seven in the greater part. The students of 45 per cent was their own cooked and more per cent in freshmen and sophomore. The majority of their parents occupation was farmer, therefore, the greater number of students thought that their parents held a conservative and authoritative way of thinking. But they considered living within a harmonious family. The economic condition of their family was 49 per cent normal situation and 44.2 per cent difficult level. So an absolute majority of students in economic problem cut down their pockect money, and wanted to work at a part-time job. The prime motive entered this teachers college was due to the inducement of their parents, or for occupation and home economic situation, those students were charged with a low mission about teaching profession. The majority of two thirds were satisfied with their subject, but one thirds desired changing their course. The major part of students took a view that the most desirable thing in personal experience during their college life was academic pursuit and substantial ability was a prime factor for success. There were no truthworthy councellor in serious situation of their personal affairs, and held counsel with their friends of thought alone its matter. However, given a chance, they hopped to discuss with a counselling professor of student guidance center. For that reason, the function of the student guidance center should be activated in counselling and guidance for solving their problems. ㅌ
Ru를 도입한 TiO<sub>2</sub>의 합성과 산소를 이용한 알코올 산화반응 연구

본 연구에서는 수열합성법을 이용하여, 한단계의 과정으로 $TiO_2$와 Ru (Ruthenium)가 도입된 $TiO_2$ ($Ru_x/TiO_2$)를 합성하였다. 합성된 샘플의 결정성과 조성 및 형태를 X-ray diffraction (XRD)과 energy dispersive X-ray spectroscopy (EDS), transmission electron microscopy (TEM)를 통하여 확인하였으며, Benzyl alcohol의 Benzaldehyde로의 산화반응에 촉매로서 적용하였다. 높은 선택성을 가지는 산화반응이 진행되었으며, $TiO_2$에 도입된 Ru의 양이 증가할수록 촉매로서의 더 좋은 촉매활성을 보였다. We synthesized $TiO_2$ ($Ru_x/TiO_2$) incorporating $TiO_2$ and Ru via an one-step hydrothermal method. The physical properties were characterized by X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDS) and transmission electron microscopy (TEM). The prepared samples were applied as a catalyst for the oxidation of benzyl alcohol to benzaldehyde using molecular oxygen ($O_2$). Especially, the catalytic activities increased as the contents of ruthenium in $TiO_2$ increased without the formation of any byproducts.
