This paper concerns with the relationship between the visual perception of the degree of pucker or wrinkles of garment surfaces and the geometrical parameters of surfaces. In this study, four potentially relevant parameters of the surface profile are considered, namely, the variance (σ2), the cutting frequency (Fc), the effective disparity curvature (Dce) (Defined as the average disparity curvature of the wrinkled surface over the eyeball distance of the observer) and the frequency component of the disparity curvature ( Dcf). Based on the experiments using garment seams having varying degree of pucker (i.e. the wrinkles along a seam line), it was found that, while the logarithm of each of these four parameters has a strong linear relationship with the visually perceived degree of wrinkles, following the Web-Fetchner Law, the effective disparity curvature ( Dce) and the frequency component of the disparity curvature (Dcf) appeared to have stronger relationships with the visual perception. This finding is in agreement with the suggestion by Rogers & Cagenello that human visual system may compute the disparity curvature in discriminating curved surfaces. It also suggested an objective method of measuring the degree of surface wrinkles.

멸치는 남해안에서는 여러 단계의 크기의 것이 혼획되는데, 가다랭이 미끼용으로는 채장 6-7m의 것이 알맞으므로, 이 크기의 것을 가급적 언중 확보하기 위해서는, 그 분포상을 조사하여 적정 자원이 가장 많이 출현하는 해역을 알 필요가 있다. 또, 멸치의 크기에 따라 상품가치도 크게 다르므로 멸치 어업을 합리적으로 운영하기 위해서나, 자원의 관리를 위해서도 채장 조사는 중요하다. 여기서는 멸치어업이 주로 이루어지는 7월부터 12월의 한국 동남 해역에 있어서의 멸치의 분포상에 관하여 조사한 것을 보고한다

최근 도심지의 초고층 건물 및 대형 구조물이 늘어나면서 고강도콘크리트 사용이 증가되고 있으며, 이를 적용한 구조물에 화재시 부재 표면이 고온에 노출될 경우 심한 폭음과 함께 콘크리트의 균열을 발생시켜 구조물의 내력이 저하시킬 수 있다. 따라서 내화모르타르를 구조부재에 활용하기 위하여 산업부산물(플라이애시, 고로슬래그 미분말)과 섬유 혼입(PP섬유, PVA 섬유, 강섬유)으로 내화모르타르의 내화특성을 비교분석하여 고강도콘크리트의 폭열방지를 위한 내화소재 개발의 기초적인 자료로 활용하고자 한다.

Robot ALICE@ERICA is a service robot developed to receive donations and to provide information services. ALICE@ERICA stands for Artificial Learning Intelligence robot for Culture and Entertainment at ERICA. In order to achieve the specific purpose of receiving donations, proper appearance design, appropriate movement and good communication skills are required in terms of HRI. In this paper, we introduce three strategies for developing robots to receive donations effectively. The first is to design a robot that makes people feel intimacy, the second is to approach only one of several people as a donor, and finally the donor communicates with video contents and voice recognition. A survey was conducted on the person who showed the reaction after the robot donated money in public places. Based on the survey results, it is proved that the method presented in this study effectively contributed to fund raising. If robots can perform actions that require high level of HRI, such as donation, robots can contribute more to human society. We hope that this study contributes to the improvement of human happiness.

There are more than 9,300 bridges on the highway, of which about 34%(3,150) are PSCI bridges. The safety of these bridges is directly influenced by the tensile strength of the internal tendons(strand) and the strength of the concrete compared to the reinforcing bars from the design viewpoint. Therefore, in this paper, for the maintenance plan considering the damage of the internal tendons, the internal tendon cutting and truck loading test was conducted and deflection and appearance status change was analyzed. As a result of the test, deflection increased and flexural cracks occurred on center of the girder. And longitudinal direction cracks followed tendon placement occurred on a bottom flange.

This study was undertaken to evaluate the association between the appearance of hypodense hepatic nodules on dynamic CT images and acute alcoholic hepatitis in patients with alcoholic cirrhosis. Sixty-two patients (male:female=57:5, mean age=51.4±10.9 years) with alcoholic cirrhosis were included. Patients were divided into 3 groups; group A (nodules, n=23), group B (fatty liver < 40 Hounsfield unit (HU) without nodules, n=18), and group C (control, n=21). Liver nodules in Group A had characteristic low density during pre- and all post-contrast phases versus liver parenchyma and fewer or complete resolution of nodules on follow up CT after alcohol withdrawal. Densities (HU) of nodules and hepatic parenchyma, ascites scores, and laboratory values were analyzed. Mean densities of hepatic parenchyma in groups A and B were significantly lower than in the control group. Serum bilirubin, AST (aspartate transaminase), ALT (alanine transaminase), PT (prothrombin time), and ascites scores were significantly higher in group A than in the other two groups. As numbers of liver nodules increased nodules’ attenuation decreased. Mean serum AST and ALT were higher in patients with many nodules than in patients with few nodules. Hypodense hepatic nodules in alcoholic steatohepatitis in patients with alcoholic cirrhosis are probably benign nodules resulting from focal steatosis or hepatocellular necrosis rather than metastases.

The seasonal appearance and the chemical composition characteristics of cladode of Opuntia humifusa were investigated in this study. The minor (horizontal) and major (vertical) axes, the width, and weight of O. humifusa cladode were compared for its appearance features. Moisture, crude protein, ash, fat, color, dietary fiber, mineral, and amino acids contents were measured for the comparison of their chemical composition characteristics. The cladode of O. humifusa harvested in summer showed higher values of minor and major axis, width, and weight than those harvested in winter. According to the results of Hunter color index, cladode of O. humifusa harvested in summer showed the highest lightness level (Hunter L value). In the meanwhile, cladode of O. humifusa harvested in spring showed the highest Hunter a (redness) and b (yellowness) values. Cladode of O. humifusa harvested in summer had the lowest crude protein and crude fat contents, while it showed the highest crude ash content. The total contents of moisture and dietary fiber were significantly greater than summer-harvested cladode of O. humifusa followed by spring- and winter-harvested cladode of O. humifusa. The major mineral content of all seasonal cladode of O. humifusa was Ca2+. Glutamic acid and aspartic acid were the major amino acids in all seasonal samples. Contrary, the contents of total amino acids and free amino acids were the lowest in summer-harvested cladode of O. humifusa. Taken together, it was concluded that the appearance and chemical quality of cladode of O. humifusa was versatile depending on the harvesting season.

The objective of this study was to evaluate grain appearance and cooked rice taste preferred by Africans for the rice ecotype of one Japonica variety, one Indica variety, and two varieties of Tongil type as compared with Korean’s preference. The preferred grain appearance by Africans who have participated as panelists was in the order of grain length, aroma, and shape, while Korean preferred rice quality in the order of appearance(head rice) and grain length. Africans preferred imported Indica rice from Thailand the most, while Korean preferred Japonica Haimi the most. Overall, African preferred aromatic rice with long grain, while Korean preferred short grain rice with high head rice ratio. In the evaluation of cooked rice taste, there was no significant statistical difference between varieties preferred by Africans. Whereas, Koreans showed clear preference in the order of Haiami > Dasan 1 = Hanareum > Indica rice. The preference analysis results of cooked rice taste subjected to Japonica and Indica which showed clear preference by Koreans revealed that Africans from Cameroon, DR Congo, and Tanzania preferred Haimai. Meanwhile, the Africans from Uganda, Mali, and Nigeria preferred imported Indica rice from Thailand. The Africans from Kenya, Malawi, Ghana, and Sudan showed similar preference among Japonica and Indica varieties. The study results indicated that Africans had different preference of cooked rice taste for eco-type rice varieties by different nations. It is regarded that additional research would be conducted to evaluate cooked rice taste by the appropriate numbers of panelists from various field and by the various rice varieties including rice variety preferred by different African countries.
