This study was to evaluate the fitness and the suitability of size specification of the ready made jacket for women by analysing pattern size and space between skin and clothing using 3D scanner. The results were as follows: 1. Pattern B had the lowest score and the feeling of wearing was significantly different among the given patterns even though all jacket size specification were the same. 2. Ease amount was different between each brand even though the jacket size specification was the same due to the different pattern grading rules. And increasing grading amounts were bigger in horizontal direction rather than in vertical direction. 3. We could obtain accurate a 3 dimensional figure, using 3D scanner which was very useful and more accurate than 2 dimensional data using photography method. 4. Analyzing the average space between skin and clothing of each pattern, there was no significant difference in the average space between skin and clothing among all patterns except waist part of B88 size. And analyzing the average space between skin and clothing of each measured body parts by each size, there existed a significant difference in the interscye, abdomen and hip parts.

시스템이 진화와 노화를 거듭하는 경우 프로그램을 이해하는데 있어서 가장 정확한 문서는 기존의 시스템 자체에서 추출되어진 정보이다. 프로그램의 이해를 돕기 위한 분석기법중의 하나인 프로그램 슬라이싱은 1984년 Weiser에 의해서 소개되어진 이후 다양한 방향으로 연구가 진행되어져 왔다. 특히, 생성되어지는 프로그램 슬라이스가 사이즈가 크고 충분히 집약적이지 못하다는 문제점과 슬라이스의 계산방법이 효율적이지 못하다는 문제점을 극복하기 위하여 여러 가지 방법들을 시도되어 왔다. 본 논문은 고전적인 슬라이싱 기준에 새로운 파라미터를 추가함으로써 제외개념을 이용하여 보다 함수적으로 응집력있고, 사이즈가 작은 슬라이스를 생성하는 선택 슬라이스를 제시하며 이 선택슬라이스를 계산하기 위한 효율적인 방법을 기술한다. 데이터와 제어의 흐름을 이용하여 선택 슬라이싱을 정의하고, 선택 슬라이싱을 위한 종속그래프를 정의하고 이를 사용하여 선형적 시간 내에 선택 슬라이스를 생성하는 알고리즘을 기술한다.

In this paper, we propose a new RLWE-based scheme named μ-Hope that exploits Error Correcting Code(ECC) on NewHope. The previous parameters of NewHope uses 12289 as a prime modulus, and the size of the public key, private key, and ciphertext is 928-byte, 1888-byte, and 1120-byte respectively, which can be said to be larger than other RLWE based algorithms. In this paper, we propose μ-Hope, which changes modulus 12289 to 769 to reduce the size of the public key, private key, and ciphertext. Also, we adopts XE1 as an Error Correcting Code(ECC) to solve the increased decryption failure rate caused by using a small prime modulus. As a result, the size of the public key, private key, and ciphertext decreased by 38%, 37%, and 37% respectively. As the computational efficiency caused by using a small prime modulus exceeds the performance degradation by exploiting ECC, this result in 25% performance improvement for a single key exchange.

LED lighting, which many companies are pursuing commercialization, is a representative green energy technology. However, the LED lighting for broadcasting image should have high output and easy portability compared with general LED lighting devices for street lamps, advertisement or transportation devices. Therefore, while shooting a broadcast image if you use LEDs as a substitute light source for halogen lamps and fluorescent lamps that are large in size and uncomfortable to handle it is expected that the lightening of the equipment will activate the broadcasting image lighting equipment industry. After considering the mass production of the LED module board and the SMT production size of the chip mounter, the board size was determined considering the overall size of the product by model. In this paper, four 20W LED boards are arranged vertically in order to produce an 80W board. In other words, by sharing LED module board size by model, high power LED lighting equipments of 120W and 200W can be selected as an increase in the number of boards.

This study was conducted to investigate the information cues in fashion magazine advertisement in 2008. A total of 368 ads executed in fashion magazine in 2008 were analyzed by number of cues, type of information, magazine type and ad size. The results show that information cues in magazine ads were remarkably decreased compare to the previous studies. Only 36.1% of the advertisements include more than 1 information cues. The results of the study also demonstrate that the advertisements in Woman Sense has the most much information cues. Interestingly, the smaller ad size includes the more information cues in all of ads.

This study aimed to elucidate the information privacy attitudes and behaviors of users of size recommendation services based on body information. Focusing on the privacy calculus theory, the effects of information privacy concerns as well as perceived risk and benefit of information disclosure on information disclosure intention were analyzed. Consumers who used size recommendation services based on body information were surveyed from August 18 to 24, 2022. Analysis of the 251 responses collected revealed that information privacy concerns did not significantly affect information disclosure intention. Information privacy concerns had a positive effect on perceived privacy risk; however, perceived privacy risk had a negative effect on information disclosure intention, while perceived privacy benefit had a positive effect on information disclosure intention. Therefore, the privacy calculus theory confirms the existence of the privacy paradox, revealing perceived privacy benefit has a greater impact on information disclosure intention than perceived privacy risk.

Existing clothing recommendation systems remain at the level of showing appropriate photos when a user selects a type of clothing he or she likes after entering his or her own body size or body size. When a user purchases clothing using such recommendation systems, there are many cases in which it does not fit or does not fit the user's body size. In this study, to solve these problems of existing clothing recommendation systems, a system was implemented in which the user receives not only size but also skin tone and recommends clothing suitable for the user's body size as well as skin tone. In this system, clothing size information obtained through web crawling was periodically stored in a database for eight male tops to recommend clothing, and the entire pixel of the clothing image was analyzed to extract color text values. In order to confirm the performance of this system, a survey was conducted on 100 male college students, and the satisfaction level was 70%. Most of the reasons for not being satisfied are that the recommended clothing is limited, so it is judged that it is necessary to expand the target clothing in the future.

회화적 렌더링의 궁극적 목적은 입력된 이미지를 가지고 손으로 그린듯한 느낌을 표현하는 것이다. 이러한 회화적 느낌을 표현하기 위한 요소에는 브러시의 위치 방향, 그리고 사이즈 등이 있다. 본 논문에서는 다음 그려질 위치가 정적 격자단위로 정해지는 것이 아닌 동적인 격자를 사용하여 결정되었다. 이때 브러시의 방향을 효과적으로 표현하기 위해 영상의 방향 보간을 하였다. 그리고 입력 영상과 캔버스의 최대 차이점에서 에지와의 거리를 고려하여 동적인 브러시의 사이즈를 표현하였다. 그리고 텍스처를 가진 다양한 브러시를 사용하여 질감을 효과적으로 표현하였다. 위의 과정들을 통하여 전통적인 오일 페인팅(oil painting)의 결과를 얻을 수 있었다.

본 논문에서 우리는 높은 채널 이용을 목적으로 하는 블루투스 무선네트웍 환경에서의 새로운 스케쥴링 기법을 제안하였다. 현재 블루투스 무선 환경에서는 다양한 사이즈의 패킷 크기를 가지는 멀티미디어 데이터를 전송하는데 RR(Round Robin) 을 많이 사용하고 있다. 그러나 이러한 스케쥴링 기법은 많은 자원의 낭비를 불러 일으킴으로서 블루투스에는 적합하지 않게 된다. 스케쥴링 기법은 QoS 서비스 그리고 시간과 슬랏과 같은 자원관리 와 같은 것을 제공하는데 있어서 매우 중요한 연구이고 우리는 본 논문에서 RR 의 자원낭비 문제점을 해결하기 위해서 DRR(Deficit Round Robin) 을 개선한 스케쥴링 기법을 제안 함으로 인해서 블루투스와 같은 환경에서 다양한 크기의 패킷사이즈를 가지는 멀티미디어 데이터를 자원낭비 없이 효율적으로 전송하는 기법에 대해서 다루게 될것이다.
