3D concrete printing technology builds structural components layer-by-layer with concrete extruded through a nozzle without using forms. This technology can simplify construction processes by optimizing design flexibility, construction time, and cost. Furthermore, the 3D printing technology is easy to make an irregularly shaped and function embedded building(or object) which is difficult to be constructed by conventional construction method. However, the 3D printing concrete is not suitable for current commercial standard and the material itself. It is also difficult to apply it to the construction site due to the lack of initial strength and the nozzle which is clogged during the process. The research of mix proportion design process for 3D printing concrete which differs from the conventional concrete is necessary in order to solve the problems. This paper aims to calculate the 3D printing concrete mix proportion design process based on the mix materials and performance information derived from the previous researches. Therefore, the usage variation range, mutual influence relationship, and the importance priority of the mix proportion are analyzed. Based on this results, the basic design process of 3D printing concrete which contains planning design phase, basic design phase and validating performance phase is suggested. We anticipate to confirm applicability verification about the actual production by referring to this 3D printing concrete mix proportion study. In the future, this study can be utilized for blueprint of the 3D printing concrete mix proportion.

The purpose of this study is to suggest standard bodytype which offers criterion for the sizes and shapes to interpret various bodytypes, to estimate fitting, and to construct ready-made clothing. There were two ways of analyzing bodytypes of subjects from the viewpoint of statistic and beauty. We had carried on the analysis from the viewpoint of statistic in the Part(1) and we carried on the analysis from the viewpoint of beauty in this Part(2). Taken as a sample, the subjects were ninety-seven females who were between the aloes of 18 and 24 rears o1d. They were measured on November 1999. The data of seven hundred and four females,18∼24 year-old, from the National Somatometry Survey of 1997 were used for analysis, too. The first analysis from the viewpoint of beauty was executed to the front and side photographs of the subjects to analyze the general traits of the beautiful bodytype. The second analysis from the viewpoint of beauty was executed to subjects who were in both High-frequency proportion range and Beautiful bodytype group. As the result, four groups in Beautiful and High-frequency proportion range were selected. The standard proportion was analyzed with the size and shape of four groups. Based on the standard proportion, the size, shape and silhouette of the standard bodytype were analyzed. To verify the size, shape and silhouette of the standard bodytype, the location of the standard bodytype in the 1997 National Somatometry Survey group was analyzed. As the result, the standard bodytype was verified as proper criterion to interpret various bodytypes, to estimate fitting, and to construct ready-made clothing.

Objectives : Previous studies showed that death certification by physicians was an important predictor to improve the quality of death certificate data in South Korea. This study was conducted to examine the proportion of death certificates issued by physicians and associated factors in South Korea from 1990 to 2002. Methods : Data from 3,110,883 death certificates issued between 1990 and 2002, available to the public from the National Statistical Office of Korea, were used to calculate the proportion of death certificates issued by physicians and to examine associated factors with logistic regression analysis. Results : The overall proportion of death certificates issued by physicians increased from 44.6% in 1990 to 77.6% in 2002 (mean: 63.5%). However, the proportion was greatly influenced by the deceased's age. In 2002, more than 90% of the deceased aged 51 or less were certified by physicians. A higher proportion was found among deceased who had tertiary education (college or higher) living in more developed urban areas. Conclusion : The information regarding the cause of death for younger, well-educated deceased in urban areas of South Korea may show a higher level of accuracy. Epidemiologic research using information on causes of death may well benefit from the continually increasing proportion of death certificates issued by physicians in the future in South Korea.

The purpose of this study is to reveal concrete evidence on how aesthetic preference is applied in product design by countries. Since the 19th century, the proportion has been examined various times, and the conclusions consistently showed the strong preference for the golden ratio (1:1.618). However, previous studies are mainly focused on western products that were designed by western designers, so when the same experiment conducted for the first time in Asia with the question of 'Is the Asian subjects also likes the golden ratio?', the result clearly revealed that Korean subjects have a significant preference for the root ratio (1:1.414) and perfect square (1:1). It demonstrates that proportion preference might be different by countries, and it also influences on everyday products. Moreover, there is not enough evidence of Asian product proportions. For this reason, this study will strive to expand the knowledge on Asian aesthetic preference by focusing on Japanese automobiles that were designed and produced in Japan. 55 iconic Japanese automobiles were analyzed for proportion and compared with 50 iconic German automobiles. The result shows that Japanese automobiles have a shorter length of 7:10 (1:1.414) ratio than German automobiles with 13:23 (1:1.769) ratio. This result proves that there is the difference in preference for the proportion of Japan and Germany, and it has already influenced on automobile proportions. This result has a strong value that finding the most appropriate proportion of automotive design is a major issue in new product development, so this can be adapted to various fields of the design process where strong cultural value exists.

디지털 게임의 등장이후 하드웨어 발전과 더불어 게임의 핵심 요소인 캐릭터는 인체비례론을 바탕으로 유저들이 선호하는 등신비율의 유형으로 변화하고 있다. 등신비율의 변화에 따른 게임에서 캐릭터의 독특한 이미지로 게이머들에게 인기가 많다. 현재까지 등신비율에 대한 연구는 아직 미흡하다고 사료된다. 본 연구는 게임캐릭터 개발에 있어 조형요소로서 인체비례가 가지는 중요성을 근간으로, 게임캐릭터들의 특성을 고찰하고, 게임캐릭터의 등신비율을 분류, 그 결과를 분석하는 연구방법을 통하여, 등신비율의 현황을 살펴보고, 앞으로 게임이미지에 미치는 영향에 대해 연구해보고자 한다. 분석한 다섯 가지 유형의 게임캐릭터는 독특한 이미지와 함께, 특성화된 등신비율일수록 유저들이 선호하며, 조형적으로 실제 인체보다 과장된 등신비율이 주를 이루는 것으로 분석되었다. 그래픽 배경화면에서 캐릭터가 상대적으로 작아 보이는 비례의 어려움을 조금 과장된 캐릭터를 활용하여 가시성을 높였다. 이 연구를 통해 게임캐릭터의 등신비율은 게임개발에 있어 게임이미지로서 매우 중요한 요소로 사료된다.

Background: In the absence of clear guidelines for facial aesthetic surgery, most surgeons rely on expert intuitive judgement when planning aesthetic and reconstructive surgery. One of the most famous theories regarding "ideal" facial proportions is that of the golden proportion. However, there are conflicting opinions as to whether it can be used to assess facial attractiveness. The aim of this investigation was to assess facial ratios of professional black models and to compare the ratios with the golden proportion. Methods: Forty photographs of male and female professional black models were collected. Observers were asked to assign a score from 1 to 10 (1 = not very attractive, 10 = very attractive). A total of 287 responses were analysed for grading behaviour according to various demographic factors by two groups of observers. The best graded photographs were compared with the least well-graded photographs to identify any differences in their facial ratios. The models' facial ratios were calculated and compared with the golden proportion. Results: Differences in grading behaviour were observed amongst the two assessment groups. Only one out of the 12 facial ratios was not significantly different from the golden proportion. Conclusions: Only one facial ratio was observed to be similar to the golden proportion in professional model facial photographs. No correlation was found between facial ratios in professional black models with the golden proportion. It is proposed that an individualistic treatment for each ratio is a rather better method to guide future practice.

This paper attempts to investigate and analyze the change of the proportion of discretionary consumption expenditure (DCE) of main consumer goods among total household expenditure from 1964 to 1986 in Korea by reorganizing various data, particularly "Annual Report of Citizen's Household Experditure in Sooul".The result of the author's analysis can be summarized as follows. 1. The analysis shows that while the proportion of DCE in food has been increased during this period as the Korean economy developed, the value of income elasticity for beverages, liguor, out-door eating and processed food products which consist of major part of food, has been successively decreased. And also, though the absolute value of income elasticity for grain products has been increased, its proportion among total expenditure has been successively decreased. From these trends, we can conclude that general consumption pattern has a tendency to change from dependence on main grain products to the more utilization of out-door eating or processed food products. 2. The ratio of DEC of furnitures to housing expenditure has played a role of indicator of business cycle, reflecting the consumers' psychological expectation fro general economic trend. 3. In case of the proportion of DCE of clothes, there has been no great change. 4. As for as DCE of sundry expenditure is concerned, there has been no-great change in The proportion itself/ However. as the ratio of sundry expenditure to total household expenditure has been greatly increased, expenditure for leisure disproportionately increased. 5. The proportion of total DCE in total consumption expenditure, as in the case of housing, has been increased, which coincided exactly with business cyele appeared during this period. In fact, when Korea economy experienced a severe recession in 193 and 1980, that proportion deeply went down respectively, and again went up after those years. Accordingly, we can generalize that the size of DCE deperds on the formation of consumer's psychological expectation toward economy, which confirms George Katona's early proposition.
