This paper deals with inter-relationship change of women's university students on the process of SW development project using social collaboration tool. Inter-relationship is one of the basic vocational competency in NCS(National Competency Standards) of Korea. We redesigned the curriculum of "Software Engineering" subject for this study and composed the project teams of students to develop software. The details of inter-relationship are satisfaction, communication, faith, friendliness, sensitivity, openness and consideration. From the result of this study, faith, openness and consideration have positive effect but satisfaction, communication, friendliness and sensitivity have no meaningful effect. The surveys were conducted in the beginning of semester and the same surveys were conducted again in the end of semester. The results were verified by paired t-test with SPSS 18.0. It is significant that the using of social collaboration tool for team project has positive effect on inter-relationship change, especially faith of women's university students. This study has some limitations for generalization but has meaning as new trial to enlarge the basic vocational competency of students in major subject, "Software Engineering". We expect new study for inter-relationship change of students to evaluate generality based on the proposed method in this paper.

A survey was conducted on 300 working women(one woman/company) who specialize in STEM(Science, Technology, Engineering and Mathematics) in the Busan region(south of Korea) to determine their job satisfaction. The overall response of women working in industry is relatively positive although they do experience a certain limit as female workers. The serious difficulties are long work hours and restriction of behavior in consequence of being the minority. Respondents anticipate an increase in number of working women in the STEM field due to the enforcement of women resource policies in Korea. Survey results about career development show that some of the most important factors in professionalism are responsibility, gumption and cooperation. The expectation of promotion is very low. Sexual discrimination is distinctly appearing in wages and promotions. If they decide to quit their job in the midstream, the key reason is in the difficulties of compatibility between home and occupation. Survey results about job satisfaction to work in industry reveal that 31.0% of respondents are satisfied because their job is consistent with their specialty; 30.7% of respondents are working where they wanted. Among respondents who intend to change their job, only 20.7% of respondents wanted to keep their specialties. Two factors involved in the respondents' satisfaction during work are special technical achievement and practical application of their knowledge. But, they are unsatisfied in terms of implementing their leadership.

Recently, research on various font designs has been actively conducted to deliver effective emotional information in a digital environment. In this study, we propose a Hangul font outline vector modification algorithm that effectively conveys sensitivity according to weather information and can be transformed immediately. The algorithm performs a series of transformations: sets outlines according to design pattern templates, calculates the glyph's position to reflect physical rules, splits outline segments into smaller sizes and deforms the outlines. Through this, we could create several vector font designs such as humidity, cloud, wind, and snow. The usability evaluation was close to good, so it can be used in diverse ways if we improve readability and effective design expression.

Responding to changes in artificial intelligence models and the data environment is crucial for increasing data-learning accuracy and inference stability of industrial applications. A learning model that is overfitted to specific training data leads to poor learning performance and a deterioration in flexibility. Therefore, an early stopping technique is used to stop learning at an appropriate time. However, this technique does not consider the homogeneity and independence of the data collected by heterogeneous nodes in a differential network environment, thus resulting in low learning accuracy and degradation of system performance. In this study, the generalization performance of neural networks is maximized, whereas the effect of the homogeneity of datasets is minimized by achieving an accuracy of 99.7%. This corresponds to a decrease in delay time by a factor of 2.33 and improvement in performance by a factor of 2.5 compared with the conventional method.

현재, 데이터베이스를 연동한 웹 스크립트 사용이 급속히 증가하고 있다. 요구되는 수요에 비해 웹 스크립트의 생성 및 변경에는 많은 시간과 노력이 소요되고 있다. 본 논문에서 소개하는 웹 스크립트 자동 생성기 WebGen은 웹 응용에 필요한 웹 폼들과 이 폼들을 통해 이루어지는 질의에 대해 데이터베이스와 연동하여 결과를 얻어 제공하는 웹 스크립트들을 자동 생성하는 소프트웨어 도구이다. WebGen은 웹 응용 개발자가 제공하는 구성파일(configuration file)에 정의된 내용을 스크립트의 기본 원형인 내장된 템플릿(template)에 반영하여 5개의 웹 스크립트들(search, select, edit, information, action)을 생성한다. action 스크립트를 제외한 나머지 스크립트들은 각각 해당되는 웹 폼을 생성한다. 따라서 웹 스크립트 생성을 위한 시간과 노력을 크게 줄여 웹 응용의 생산성을 향상시킨다. 또한, WebGen은 템플릿 기반이기 때문에 생성된 스크립트들과 WebGen 자체의 유지 보수를 효율적으로 할 수 있다.

The purpose of this study is to most appropriately develop maternity wear according to the preferences of specific age groups of pregnant women. The specific age groups were women in their twenties, early thirties, and late thirties. This survey was conducted in the metropolitan area around Seoul, South Korea through a questionnaire given to 150 pregnant women. The study found that pregnant women purchased significantly cheaper clothes after their pregnancy than before. The participants responded that they mostly bought clothes using the Internet, but they also reported many instances of returning the clothes due to fit and sizing. It was shown that women in their twenties tended to consider the price, design, and activity more than women in their thirties when purchasing maternity wear. The study showed that pregnant women tended to wear maternity wear from early in the pregnancy-preferring leggings, one-piece dresses, pants, shirts, briefs, and bras with the girdle on the outside. More women in their late thirties purchased maternity support belts than younger age groups. In any case, in purchasing maternity wear, clothing features that the respondents focused on were comfort, functionality, fit, the covering of their body changes, and fashion. Still, many respondents 35 years and older reported more interest in safety rather than fashion in comparison to the responses of respondents under the age of 35.

Voice Command systems are important means of ensuring accessibility to digital devices for use in situations where both hands are not free or for people with disabilities. Interests in services using speech recognition technology have been increasing. In this study, we developed a mobile writing application using voice recognition and voice command technology which helps people create and edit documents easily. This application is characterized by the minimization of the touch on the screen and the writing of memo by voice. We have systematically designed a mode to distinguish voice writing and voice command so that the writing and execution system can be used simultaneously in one voice interface. It provides a shortcut function that can control the cursor by voice, which makes document editing as convenient as possible. This allows people to conveniently access writing applications by voice under both physical and environmental constraints.
