The basic factor that affect wear performance is the wear characteristics, which come from sliding friction between rubber compound and road. Thus, this study focused on friction and wear of rubber. This paper briefly explain some characteristics of friction and wear referring to the papers on wear of rubber that scholars researched on. Research activities to predict the performance of the rubber wear is also explained.

베트남 민족의 가정과 사회에 대한 이해를 제고하기 위한 방편으로써 베트남의 전통상례와 그 특징을 내재된 전통 관념을 중심으로 고찰해 보고자 한다. 본 논문의 구성은 2장에서 연구 주제로 삼고 있는 베트남 전통 상례의 형성 과정과 배경을 사료 중심으로 검토, 정리하고, 3장에서는 그 절차와 관련 풍습을 살펴본다. 4장에서는 베트남 전통상례의 특징을 각 절차에 내재되어 있는 관념을 중심으로 고찰하고, 마지막 결론에서는 베트남 전통상례의 특징을 종합, 정리하고 그로부터 베트남인의 전통 관념 상 민족적 특징을 도출하여 본다. 본 논문에서는 베트남인이 17세기 후반부터 중국의 육례(六禮)를 근간으로 비로소 격식과 절차를 갖춰 행하기 시작한 상례를 베트남 전통상례로 본다. 그리고 베트남이 54개 민족으로 구성된 다민족 국가임을 고려하여 현재, 다수 민족으로서 전체 인구의 약 87.5%를 차지하고 있는 낀(Kinh)족의 전통 상례를 연구 대상으로 한다. 한편, 전통상례에 있어서 지역 간 그 형식과 내용에 다소 차이가 있음을 고려하여 특정 지역에 대한 구분 없이 베트남 전 지역에서 보편적으로 행하여지고 있는 전통상례를 논하기로 한다. This paper examines Vietnamese traditional funeral rites and its features based on Vietnamese inherent tradition in order to understand Vietnamese homes and society more deeply. The structures are as follows: in Chapter 2, it investigates the historical records to see how the traditional funeral rites had been established; in Chapter 3, it finds the detailed process and customs of the funeral rites; in Chapter 4, it studies the special features of Vietnamese funerals which can be found in each process; in conclusion, it summarizes and infers the general features of Vietnamese society from its funeral rites. This paper regards the traditional funerals as formal ones based on Chinese "six manners" originated from the late 17th century. And considering the multiracial nation of 54 races, it focuses on the rites of Kinh race, who constitutes 87.5% of the total population. In addition, this paper discusses the traditional funerals which are universal in Vietnam, not distinguishing the regional differences.

Today"s Vietnamese people frequently use the Vietnamese Chinese characters prover who translated the Chinese story in Vietnamese in the everyday life and the Vietnamese proverb which translated literally by interpreting its original meaning in Vietnamese. These proverbs are attributed to the fact that during the Vietnamese rule of China, which lasted more than a thousand years, the letters are not deeply rooted in Vietnamese language culture. Furthermore, even after independence from China of Vietnam, Chinese character are spread more widely in society through encouragement and dissemination of each feudal dynasty in Vietnam, and as a result, in Vietnamese vocabulary of today"s modern Vietnam Chinese character words which are read in the range are made to account for about 70% or more. The influence of such Chinese character shows that the biggest root of Vietnamese language culture is Chinese character as one of the biggest features of Vietnamese language culture. This means that two countries have many similarities in language culture. In particular, as a proverb is transmitted through many years, as a language of the common people inherited from the predecessors who have lived in each era, its traditional notions based on traditional beliefs, values, wisdom, etc. of that nation It is inherent in China, collecting the proverbs of Vietnam originating from the story rooted in the Chinese story, and investigating its meaning and its participation, not only the influence on the Vietnamese proverb of Chinese pretext, as well as China Culture may be a means to understand the influence of Vietnamese traditional ideas.

베트남의 부패, 그 특징과 원인에 대한 고찰

김현재(Kim Hyun Jae) 한국부패학회 2008 한국부패학회보 Vol.13 No.2

This study is aimed at analyzing the corruption inside the Vietnamese society whose economy has been growing drastically after Doi Moi policy. In order to understand the corruption in Vietnam, which is increasing rapidly at the degree which might threaten the socialist system, it is required to analyze the real condition, a feature, and a cause of the Vietnam corruption. Therefore, this study analyzes the real condition and a feature of Vietnam corruption with those of corruption among government officials, and then looks into the systematization of corruption and the routine of bribery which is called 'tien hoi lo.' And then, It analyzes the root of corruption from three aspects: first, there are moral thought and familism on the behavior pattern; second, there are handing a public position down to posterity and low wages of public official; third, there are the vietnamese traditional gift culture and the development of the black market. Finally, referring to the cause drawn from above analysis, this study finds out that the corruption is widely spread in the whole Vietnamese society with centering on officialdom, and that it has its systemized characteristics.

A steam expander has been studied for its usability as a power conversion device in a Rankine cycle, which can be used for on site power generation or waste heat recovery. Design of swash plate type expander has been practiced and its performance has been estimated. With the steam pressure and temperature of 35bar and 300℃ at the expander inlet, respectively, it was calculated that the expander produced the shaft power output of about 5㎾ from steam energy of 35㎾. Adiabatic and mechanical efficiencies of the designed expander were 86.5% and 96.7%, respectively. With the volumetric efficiency of 90%, the total efficiency of the expander was 75.3%.

콘택트렌즈용 하이드로젤로의 단백질 흡착량을 시간에 따라 분석하여 계면으로 확산되는 단백질 흡착 반응속도를 연구하였다. HEMA(hydroxyethylmethacrylate)계열 하이드로젤과 silicone계열 하이드로젤을 단백질(알부민 또는 IgG)용액에 침지시킨 후 단백질 흡착량을 시간에 따라 측정하였다. 모든 하이드로젤로의 단백질 흡착량은 단시간(10분)에 급격히 증가한 후 90분 동안 변화 없이 일정하였다. 빠른 단백질 분자의 확산에도 불구하고 계면에너지감소는 한 시간 이상 진행되는데 이는 계면 탈수 현상이 한 시간 이상 진행되기 때문으로 이해된다. 계면에너지와 단백질 흡착량의 상관관계를 이해하여 콘택트렌즈 재질로의 단백질 흡착 반응 속도의 메커니즘을 분석하였다. Protein adsorption kinetics was studied with the amount of proteins adsorbed to contact lens hydrogels over time scales. Hydroxyethylmethacrylate (HEMA) and silicone hydrogels were dipped in protein solutions (albumin or IgG) and adsorption amounts were measured over time scales. The amount of protein adsorbed to both hydrogel types increased rapidly in 10 min, and remained consistently in 90 min. Decreasing interfacial energetics was taken slowly up to an hour in spite of rapid diffusion of protein molecules. This is due to the fact that water deprivation from three dimensional interphase initially formed by protein diffusion took over an hour. Interpretation of adsorption kinetics on contact lens hydrogels was discussed with understanding of relationship between surface energy and protein adsorption capacity.
