In this paper, the front radiuses of curvature of spherical spectacle lenses in the cosmetic and optical point of view are investigated and are calculated using Zinken-Sommer condition. The optical power of all spherical spectacle lens shows good quality at the test using autometic lensmeter. However the front radiuses of curvature of spherical spectacle lenses are quite different depending on the lens companies. The front radius of curvature of those lenses is larger than that calculated using Zinken-Sommer condition. We know that the front radius of curvature of commercial spectacle lens is emphasized more cosmetic aspect than optical point of view.

The purpose of this study is to analyze the image evaluation and the preference of tailored jacket according to the body type and the degree of satisfaction with their body of middle-aged women. The subjects used for this study were three hundred and twenty three middle-aged women ranging from 35 to 50 years old. We measured their bodies and asked them report to the questionnaire. The results are as follows. 1) Middle-aged women were classified into four typical types of body. The type 1 was tall and thin and had a front view silhouette with the form of a letter X. The type 2 was the tallest and the medium of fatness and had a front view silhouette with the form of a letter H that the lower part of the body is short. The type 3 was the medium of height and width and had a front view silhouette with the form of a letter A that the upper part of the body is short compared with their height. The type 4 were the shortest and the fattest and had a front view silhouette with the form of a letter Y that the lower and upper parts of the body is the longest. 2) Middle-aged women roughly tended not to be satisfied with part of their body. The results showed that a neck was the most satisfied body part and the weight was the least satisfied as well as overall leg shape among all 13 body parts. 3) The type 1 had the highest the degree of satisfaction on their face size, upper arm girth, waist, hip girth, weight and body shape, etc., excepting hip shape among 4 body types.

This study analyzes difference in consumers' and front-line workers' perceptions on 'consumer complaint behavior with hateful intentions' though the Co-orientation Model in three dimensions. In addition, we seek to contribute to reducing the conflict between consumers and front-line workers in the service contact point by finding factors that affect the difference in perception between two parties. This study findings and implications are as follows. First, Taking a look at the mutual orientation between consumers and front-line workers, mutual perceptions have been found to match in agreement but with a significant difference in perceived agreement (congruence), which indicates that the internal perceptions of both consumers and front-line workers do not match. The findings confirm that consumers and front-line workers have different perspectives on consumer complaint behavior with hateful intentions and therefore raise a need for efforts and institutional devices for improvement. Second, the study has found that consumers' economic responsibility as part of their social responsibilities and front-line workers' perceptions on consumers' civic responsibility affect the perception difference between these two groups and suggest a need for educating consumers about economic responsibility. Meanwhile, unlike consumers, front-line workers view consumers' complaint behavior with hateful intentions from an ethical point of view, raising a need for a transition of perspectives on complaint behavior with hateful intentions.

A business process flow model for an intermediary type shopping mall consisting of multiple sellers has been presented in this study. Specifically, we defined 11 essential business processes of a front office customer's view point and set up detailed process flow models using IDEF3 (Integrated DEFinition). The characteristic of this study lies in providing a dynamic model rather than static models. The results may form a conceptual framework not only for shopping mall processes but for analysis and improvement toward extended electronic business systems.

An automated process planning system for cold forging of non-axisymmetric parts of comparatively simple shape was developed in this study. Programs for the system have been written with Visual LISP in the AutoCAD using a personal computer and are composed of four main modules such as input module, shape cognition and shape expression module, material diameter determination module and process planning module. The design rules and knowledges for the system are extracted from the plasticity theories, handbook, relevant reference and empirical knowledge of field experts. Generally, in forging, only front view is needed for expression of axisymmetric parts, but non-axisymmetric parts need front and plane view. At the plane, this system cognizes the external shape of non-axisymmetric, parts - number of sides of regular polygon and radius of a circle circumscribing the polygon of n sides. At the front view, the system perceives diameter of axisymmetric portions and height of primitive geometries such as polygon, cylinder, cone, concave, convex, etc.

In real world object detection is an active research topic for understanding different objects from images. There are different models presented in past and had significant results. In this paper we are presenting vehicle logo detection using previous object detection models such as You only look once (YOLO) and Faster Region-based CNN (F-RCNN). Both the front and rear view of the vehicles were used for training and testing the proposed method. Along with deep learning an image pre-processing algorithm called perspective transformation is proposed for all the test images. Using perspective transformation, the top view images were transformed into front view images. This algorithm has higher detection rate as compared to raw images. Furthermore, YOLO model has better result as compare to F-RCNN model.

This paper describes a crashworthy design for the front structure of KHST (Korean High Speed Train) under the SNCF accident scenario (collision against a movable rigid mass of IS tons at 110 km/h). The front structure designed in a new concept shows good behaviours in crashworthy point of view. It collapses in a progressive and well-controlled fashion. To evaluate the design by considering real situations, the power-car is simulated for accidents collided against a dump truck of 15 tons at 110 km/h. The front end structure of it shows a good response on crashworthiness.

The use of tailor welded blanks (TWB) in automotive applications is increasing due to the potential of weight and cost saving. The object of this study is development of the front side member by static analysis and crash simulations. Accord-ing to the results , energy absorption and barrier force is very important parameter to control passenger safety and deforma-tion shape. A energy absorbability point of view, tailor welded blanks is most effective to absorb energy than non-twb. Non-TWB front side member and TWB applied front side member were simulated. It shows reduce stmping parts weight reduction and cost down.

The purpose of this study is to present objective basic data for environmental design by the quantitative analysis of visual quality emboded in physical environment. For this, as for the front garden of high schools, the spatial image was measured by the S.D. Scale Method, Factor Analysis was proceeded by the principal component analysis and the visual preference was investigated by the Paired Comparision Method. The scale values of plain and unpleasant road surface and external appearance of buildings, which are related to emotions of simpleness fell from straightness and stability, were found to be high. But, except for the road surface of Kyunggi High School, scale values of variables explaining the variation of the quality of materials, level of floor and rythm were generally low. For all green spaces, scale values of variables explaining the degree of pleasantness was found to be generally high. And, those explaining tidiness and characteristics of green spaces were not in the same tendency. But, the green spaces of Youngdong High school can be considered to the space with plenty of visual absorption uniqueness were high. As for the correlation between variables, variables for green spaces(12 and 26) and those for overall view of front garden( 1 and 4) revealed high positive correlation. Also, "order - disorder" and "convenient- incovenient" included in road surface variable can be regarded to have the same meaning since the correlation coefficient between them is very high, 0.7045. Image variables including road surface, external appearance of buildings, green spaces and overall view of front garden showed 91.21~61.08% of total variance. Thus, the remains can be considered to be the error valiance or specific variance. In Fctor I, II and III, main components explaining the road surface image of front gardens are order, hardness, texture, color, gradient and rythm. As for the external appearance of b wilding, variables of color, hardness, stability, peculiality and shape revealed high values of factor load. For all variables, communality was drastically high and ellen values and common variance were found to be very high in Factor I. As for the front gardens, variables explaining volume and peculiarity were found to be the main components of Factor I. In Factor II and III, variables of factor load were tidiness, pleasantness.

The purposes of this study are to examine the characters of the lower body shape in the middle aged women and to make slacks pattern on the base of four difference body shapes. The lower body shapes were classified into 4 types on the basis of their lateral view silhouettes. The slacks patterns were based on the lower body shape characters and resulted in followings. In “Type 1” of the right body shape with the standard protrusion of abdomen and hips, little difference from conventional patterns was seen in experiment pattern, in which the front waist girth was W/4+0.5㎝+0.5㎝+fold(2.5㎝) and the back waist girth W/4+0.5㎝-0.5㎝+dart(3.5㎝). The front hip girth was defined as H/4+2.0㎝+0.5㎝ and the back hip girth as H/4+2.0㎝-0.5㎝ due to its increased ease amount produced by abdominal fat deposition. In the experimental pattern of “Type 2” with prominent hips, the front and back differences of the waist girth and the hip girth and the hip girth were defined as 1.0㎝ and 2.0㎝ separately. Accordingly, the front waist girth was W/4+0.5㎝+1.0㎝+fold(2.0㎝), the back waist girth W/4+0.5㎝-0.1㎝+dart(6.5㎝), the front hip girth H/4+2.0㎝+1.0㎝ and the back hip girth H/4+2.0㎝-1.0㎝. In “Type 3” with the prominent abdomen and the flat hips, the front waist girth was set up as W/4+0.5㎝+0.5㎝+fold(4.5㎝) for the increased front fold amount and the back waist girth was W/4+0.5㎝+0.5㎝+dart(3.0㎝). The front hip girth was made as H/4+2.5㎝+0.5㎝ and the back hip girth H/4+2.5㎝-0.5㎝. In “Type 4” with prominent abdomen and hips, considered were ① the increased front fold amount due to the abdominal protrusion, ② the increased back dart amount and the decreased back dart length owing to the hips prominent and ③ the front and back differences of waist and hip girth for the lateral view silhouette. Therefore the front waist girth was defined as W/4+0.5㎝+2.0㎝+fold(5.0㎝), the back waist girth as W/4+0.5㎝-2.0㎝+dart(4.0㎝), the front hip girth as H/4+2.0㎝+1.0㎝ and the back hip girth as H/4+2.0㎝-1.0㎝. The sensory evaluation of appearance and comfort was appeared more suitable on the experiment pattern than on the conventional pattern.
