This study was initiated to investigate (1) the current sizing system for mail-order clothing, (2) consumers' preference for sizing systems, and (3) consumers' satisfaction with garment size. The apparel items and the sizes available at various mail-order companies in Korea were also reviewed. This investigation of consumers' preferences for various size description systems includes a survey of 410 men and women who had purchased garments by mail-order. The data were analyzed by Statistical Analysis System/pc. The major results are as follows; 1. The sizing system of mail-order clothing was different by garment items. The number of apparel sizes available for mail-order purchasing was three or less. The most mail∼order garments were labeled by the numerical size codes of body girth nleasurements or letter code (S, M, L). 2. The size description system most prefered by female subjects(N : 360) was the numerical size code of a body measurement(55.4%). The combination of bust-hips-height measurements size codes were prefered by 13.3% . The pictogram was least premiered by the subjects. 3. The apparel items that subjects wanted to buy using mail-order were underwear, home -weat and night-wear. The heavy users of mail-order purchasing, however, also wanted to purchase expensive garments requiring precise fit. The subjects aged from 20's to 80's wanted to purchase childern's wear by mail. 4. The desire for diversity of garment item and size of mail-order apparel was relatively high. The subjets also wanted to purchase special size garments by mail-order, e. g., garment sizes for full or tall figure.

In this paper, we identify the code vulnerabilities that can be automatically detected through Visual Studio (VS) compiler and code analyzer based on a secure coding rule set which is optimized for development of battlefield information system. Then we describe a weak point item that can be dealt with at the implementation stage without depending on the understanding or ability of the individual programmer's secure coding through the implementation of the secure coding library. Using VS compiler and the code analyzer, the developers can detect only about 38% of security weaknesses. But with the help of the proposed secure coding library, about 48% of security weaknesses can be detected and prevented in the proactive diagnosis in the development stage.

Background The purpose of this study is to analyze the current attitudes toward professionalism, the core values, and the type of professionalism among plastic surgeons in Korea to establish a code of ethics regarding the role of professionalism for plastic and reconstructive surgeons. Methods From March 9, to July 1, 2012, face-to-face and mail surveys were conducted targeting the 325 participants (256 specialists and 69 residents) who are registered members of the Korean Society of Plastic and Reconstructive Surgeons. The proportion of each response given to an item was obtained through statistical processing through frequency analysis. The Mann-Whitney U test was used to compare the differences in the responses between the resident group and the specialist group. Results The survey results on the perception of professionalism in plastic surgery showed that a high proportion (90.5%) of the respondents viewed the future of plastic surgeons as bright. Through evaluation of the importance of the value items,"professional dominance" (4.58 pts), "autonomy" (4.45 pts), "lifestyle" (4.34 pts), and "commercialism" (4.31 pts) were assessed as critical values. "Altruism" (3.84 pts), "interpersonal competence" (3.79 pts), and "social justice" (3.61 pts) were viewed as lesser values. This difference showed the characteristics of an entrepreneurial outlook. Conclusions Plastic surgeons should pursue excellence, humanism, accountability, and altruism in order to overcome the crisis of professionalism in plastic surgery. In order to develop the necessary competencies of professionals, vocational education should be arranged by the Korean Society of Plastic Surgeons, and an appropriate code of ethics should be established.

As construction projects increase their complexity, variety, and scale, various recognition applications (such as RFID, bar-code etc.) have been tried for managing material effectively in construction projects. However, existing recognition applications for construction material management have some limitations that cause additional works (such as attaching RFID tag), additional cost (labor cost, recognition device cost, etc.), and cognitive impairment of workers. Therefore, this study proposed a character recognition technology as an alternative of previous recognition technologies such as RFID, bar-code, etc. The technical feasibility of proposed technology was validated by three recognition tests. Additionally, this study proposed code the structure to manage materials using the character recognition technology. The effects of character recognition technology are presented by comparing with existing RFID-based logistics processes.

최근 이동체 또는 센서 데이터에 대한 연속 질의를 처리하기 위해 다양한 질의 색인 기법들이 연구되고 있다. 그러나 RFID 미들웨어는 이전 연구에서 고려되지 않은 특징이 존재한다. 첫째, 질의 색인에 삽입되는 질의는 Industry, Product, Serial의 세 부분으로 구성되며, 각 값은 범위 값으로 표현될 수 있기 때문에 색인 공간에서 비연속적인 간격의 조각들이 반복해서 나타난다. 둘째, TagID가 가지는 Industry, Product, Serial의 값은 포함관계를 가진다. 즉, 하나의 Industry에 여러 Product가 존재하며, 하나의 Product에 여러 Serial Item이 존재한다. 따라서 이러한 특징을 고려하지 못하는 기존의 질의 색인을 적용하면 다수의 질의 조각을 삽입하게 되어 색인의 성능이 급격히 저하되는 문제점이 있다. 이 논문에서는 RFID 미들웨어의 실시간 필터링 및 컬렉션을 위해서 Tag 스트림에 대한 질의 색인 기법을 제안한다. 이 논문은 ECSpec 필터링 범위의 3단계 계층구조 특징을 고려한 코드 분할(Code Segmented) 도메인을 제시하고 이를 위한 그리드 기반 색인 구조를 제안한다. 또한 ECSpec의 필터링 패턴 특징에 의해 나타나는 질의 조각의 반복 현상을 정의하고 이를 위한 질의 처리 기법을 제시한다.

Though limited, Model Human Processor (MHP) has been used to explain the complex users' behaviors during human-computer interactions in a simplified manner. MHP consists of perceptual, cognitive and motor systems, each with processors and memories interacting with each other in serial or parallel mode. The important parameters of memory include the storage capacity, the decay time, and the code type of a memorized item. The important parameter of a processor is the cycle time. Using these features of the model, this study developed a computerized cognitive process simulator to predict the cognitive process time of a class match task process. An experimental validity test result showed that the mean prediction time for cognitive process of the class match task simulated 50 times by the simulator was consistent with the mean cognitive process time of the same task performed by 37 subjects. Animation of the data flow during the class match task simulation will help understand the invisible human cognitive process.
