The present study aimed to determine the test-retest reliability of subjective visual horizontal (SVH) testing when tested with solid and dotted line images. In this repeated measures study, 36 healthy young Malaysian adults (mean age=23.3±2.3 years, 17 males and 19 females) were enrolled. All of them were healthy and had no hearing, vestibular, balance, or vision problems. The SVH angles were recorded from each participant in an upright body position using a computerized device. They were asked to report their horizontality perception for solid and dotted line images (in the presence of a static black background). After 1 week, the SVH procedure was repeated. The test-retest reliability of SVH was found to be good for both solid line [intraclass correlation (ICC)=0.80] and dotted line (ICC=0.78). As revealed by Bland-Altman plots, for each visual image, the agreements of SVH between the two sessions were within the clinically accepted criteria (±2°). The SVH testing was found to be temporally reliable, which can be clinically beneficial. Both solid and dotted lines in the SVH testing are reliable to be used among young adults.

본 연구는 서비스산업 육성정책의 방향을 서비스의 본질 관점에서 연구하였다. 서비스산업의 범위가 넓고 업종이 다양하기 때문에, 서비스의 본질과 특성을 고려하지 않고 개별적인 산업의 특성을 중심으로 발전전략을 수립하면 한정된 시각을 가지게 되어 큰 발전을 추구하기 어렵다. 더구나 산업간 경계가 해체되는 현대 경제에서 중요한 변화를 간과할 수 있다. 또한 서비스산업간의 시너지를 추구하기 어렵고 개별산업의 혁신적 발전을 추구하기도 어렵다. 따라서, 각 개별서비스산업은 모두 서비스라는 공통적인 재화를 가진 산업임을 인식하여, 서비스의 본질 차원을 고려하여 발전전략을 설계할 필요가 있다. 본 연구는 서비스의 관계성, 쌍방향성, 수평성, 조화성 본질과 서비스의 무형성, 비분리성, 비일관성, 무재고성 특성을 반영하여 개별 서비스산업의 육성 전략을 도출해내는 시범연구로 수행되었다. 개별 서비스산업에서의 향상된 발전전략 수립과 정부의 발전정책 개발에 활용될 수 있을 것이다.

The purpose of this study is to propose a design method for one-piece dress patterns with high body fitness through an appearance evaluation of one-piece dress patterns with the application of the 3D Virtual Clothing System known as i-designer. Measures consisted of an optical illusion effect in visual imagery and mutual influence according to a change in the length and princess line, in a silhouette of a one-piece dress. The data was assessed by a t-test and a multi-way ANOVA and factor analysis using SPSS 17.0. The results were as follows; The design of the study pattern was done by modifying the ease of the bust circumference, ease of the abdominal circumference, ease of the hip circumference, the position of the side seam line, and the appearance of horizontality in the hem line, which received a low evaluation in appearance evaluations of a one-piece dress pattern. As a result of analyzing the visual image according to a change in the length and princess line, in the form of a silhouette of a one-piece dress, four factors were selected; the whole-body optical illusion factor, the upper-body optical illusion factor, the bust optical illusion factor, and the lower-body optical illusion factor. As a result of analyzing the effect of the interaction in the visual image according to the design variables, the influence of the main effect was found to be great in each factor. In the upper-body optical illusion factor, a significant difference was not noted in the two-way interaction between the length and the princess line. However, the influence on three-way interaction among the length, princess line, and silhouette was significant.

일반적으로 대형 지붕구조나 초대형 보와 같은 대형 구조물을 양중하는 방법은 유압잭이 이용된다. 또한, 양중시 안전을 위하여 CCTV를 이용하여 각 포인트에 설치된 줄자를 모니터링하여 레벨체크를 수행하고, 상대 변위가 기설정된 한계를 벗어나면 유압잭을 정지하고 상대변위를 수동으로 조정한 후에 양중을 수행하였다. 그러나, 이러한 종래의 양중 방법은 CCTV를 육안으로 확인하여 레벨을 체크하기 때문에 정확도가 높지 않았고, 실시간 계측은 현실적으로 불가능하였다. 이러한 문제를 개선하기 위하여 자동추적형 토탈스테이션, 레이저 거리계, 데이터로거, 변형도게이지 등을 이용하여 대형 구조물 양중시 적용할 수 있는 계측-평가 시스템 구축하였다. 시스템을 구현하기 위한 프로그램 작성 후 실험실에서 시연을 통해 계측-평가 데이터의 정확성 및 활용 가능성을 평가하였으며, 안정적인 데이터 취득 및 연산을 통해 적용성이 검증되었다.

In this study, fitness tests for slacks were divided into shape fitness test and motion fitness test, and the fitness test conditions for slacks were designed as the first step for standardization of measuring scales. Shape fitness test consisted of analyzing the parameters of appearance sensory tests as described in preceding studies, performing a simulated appearance sensory test, collecting and considering apparel experts' opinions about the test parameters, and establishing test conditions in terms of test regions, descriptions and faces. For the regions of the abdomen, hip, crotch, thighs, and knees, the parameter of unnecessary wrinkle/stretch was observed from the anterior and posterior body, and then evaluated; for waist, hip, crotch, knee and hem circumference, the parameters of ease and horizontality were observed from the anterior body and posterior body followed by evaluation; and, at the levels of waist, hip, crotch, knee and hem circumference, the division of the lateral line were observed from the lateral body followed by evaluation. Motion fitness test was composed of reviewing and analyzing comparatively the methods of motion fitness tests as mentioned in preceding studies, and establishing test conditions in terms of test motions and test regions. For each of the waist, abdomen, hip, crotch, and knees, wear sensation was tested in the positions as follows: upright standing, moderate walking, chairsitting, bending forward to the maximum, and kneeling down, provided that as the measured points of garment pressure, anterior waist, abdominal protrusion, buttock protrusion, crotch, and midpatella were set and tested.

This research analyzed the expression trend about the slit which composes the open space by the visual concept and then introduced the imbedded aesthetic value in it. Based on it, this work aims at showing the evidence on the slit as a utilizing tool for various design applications and providing the basic materials in order to develop the creative design production in the fashion area in the future. Specifically, for the theoretical background in this research, the concept of slit and its chronological changes were reviewed through literature. For the empirical analysis on the slit, a total of 226 designs with its application were analyzed from collection pieces in the four major collections including Paris, Milan, New York, and London from 2006S/S to 2012S/S. As a result of analysis, types of slit appeared as a slash, opening, slit, or a mix of them. These were applied to many different items of clothing, and among which, one-piece or dress was adopted most for application. In regard to space form, perpendicularity was used most frequently. But other various forms like cross and geometrical pattern were also used as well as curve, oblique line and horizontality. As to the arrangement of slit, single type was most frequently used. However, in addition to it, other types were also applied, producing both the functionality and the decorative detail such as bilateral symmetry, free irregularity, and a combination of regular and repeated layout which makes an effect of single pattern. Aesthetic values imbedded in slit were revealed as functionality, sensuality, spatiality, and decorativeness.

본 논문에서는 질감분류를 위해 블록영상 내에서 인접 화소사이의 다차원 명암차이를 이용한 local binary pattern(LBP) 기법을 제안한다. 여기서 블록영상 내 화소 간 명암차는 4방향(세로, 가로, 대각, 역대각) 각각의 인접 화소 간 밝기변화를 고려한 것으로 영상의 질감분류에 이용되는 히스토그램의 레벨수를 감소시켜 계산 부하를 줄이기 위함이다. 또한 블록 내 명암관계를 이진패턴으로 나타낸 것으로 영상의 국부적 속성을 더욱 더 정확하게 반영하여 효과적인 질감분류를 가능하게 함이다. 제안된 기법을 128*128 픽셀의 그레이 영상 USC Texture Mosaic #2을 대상으로 크기와 질감이 다른 24개의 블록영상 각각을 분류하는 실험결과, 기존의 LBP에 비해 빠른 분류속도를 가지며, 임의 크기 블록영상의 분류도 가능함을 확인하였다. 특히 블록영상의 크기가 증가할수록 히스토그램의 레벨 감소폭이 더욱 더 크게 되어 분류속도의 개선정도도 증가함을 알 수 있다.

The purpose of this study is to analyze size and proportion of plan and section, and derive characteristics by types of worship-space in central hall of buddhist temple. This study covers 45 buddhist temples as designated national treasure and treasure. Types of central hall of buddhist temple are 'Columnless Type', 'Inner Column Type', and 'Colonnade Type'. The results are as follows. Firstly, in the proportion of width and length, 'Columnless Type' is mostly represented with 1:0.73, 'Inner Column Type' with 1:0.54 and seems to be widening for the other types, and 'Colonnade Type' is same proportion with 'Columnless Type'. Secondly, in the proportion of width and height, 'Columnless Type' is 1:0.61 and sizes of worship-space of this type are different but the proportion is same. In the 'Inner Column Type', worship-space is enlarged because a buddhist altar is hustled into the rear. Thirdly, in the proportion of length and height, all types are represented with similar proportion as 1:1. Finally, proportion of the volume of worship-space in 'Columnless Type' is 1(width):0.74(length):0.60(height). The case of 'Inner Column Type' is 1:0.57:0.57 and length of worship-space is shortened, so characteristics of horizontality is emphasized. The space of same size with the proportion of 'Columnless Type' is situated in the inside of worship-space in 'Colonnade Type'.
