Most users learn new, complex systems through trial-and-error experience rather than referring to the manuals in a cognitive process that is called 'exploratory learning'. While exploring a system, people find prototypical rules for using the system based especially on frequent tasks. The rules are formed from consistent task procedures and well-expected interface elements on the designed system. These rules play the role of the basis of users' knowledge for performing tasks. The decision making to select and apply those rules interacting with an interface can be aided by properly provided hints on the interface. With appropriate hints, users can learn new systems easily and use them with reduced usability problems. This paper first reports an observation of user behavior performing tasks with prototypical interaction rules and finds a sound set of criteria to extract prototypical interaction rules systematically. Two types of hints are defined. Extending hints prompt users to apply prototypical interaction rules beyond well-known tasks. Preventive hints guide users out of possible capture errors by drawing attention to the variation of rules. A systematic and practical method is proposed to identify the opportunities for both types in designing interfaces. It is then verified through a usability test that the proposed method is effective in identifying the locations and types of appropriate hints to reduce or mitigate usability problems.

Most malignant mesenchymal tumors of the lung are metastases of a primary tumor from elsewhere in the body. A primary pulmonary synovial sarcoma is a very rare neoplasm that accounts for approximately 10% of soft tissue sarcomas and makes up only 0.5% of all primary lung malignancies. We report a case of a primary pulmonary synovial sarcoma in a 60-year old woman. In this case, a lung metastasis was excluded using 18F-FDG PET/CT imaging. (Tuberc Respir Dis 2006; 60: 673-677)

Arsenic keratosis can be a precursor of both Bowen`s disease and squamous cell carcinoma. In fact, there is a direct dose-response relationship between the amount of arsenic exposure and the development of skin cancer. Therefore, meticulous dermatologic surveillance and follow-up are advised to detect malignancy at an early and curable stage. We herein report on a case of a 62-year-old man who presented with multiple Bowen`s disease and arsenic keratosis. His past history revealed chronic exposure to arsenic through consumption of Chinese traditional herbal medicine. After a follow-up loss of 2 years, he returned with multiple extracutaneous metastases of squamous cell carcinoma, including the liver. Our case emphasizes the importance of regular follow-up and survey for skin cancer and other internal malignancies in patients with history of chronic arsenic exposure.

The purpose of this research was to investigate the relationship of family related variables with adolescents` delinquent behaviors. Family related variables were consisted of (a) family`s general characteristics (i.e., occupation. income, etc.) and (b) family relationship charateristics (i.e.. parents` child rearing attitude, parents` marital relationship. and communication level between parents and adolescent children). Adolescents` delinquent behaviors were also analyzed according to adolescents` general charateristics such as sex, grade, birth order, school achievement level, and religion. The data were collected from 577 middle and high school students in Chonju by using self-administered questionnaire method. Results showed that there were significant differences in the frequency level of adolescents` delinquent behaviors across adolescents` sex, grade, birth order, school achievement level, and religion, and across mother`s occupation, and subjective living level. The delinquent behaviors were also negatively correlated with most of family relationship characteristics. Results of multiple regression analyses indicated that communication of adolescent children with their father and mother`s child rearing attitude were most significant variables influencing adolescents` delinquent behaviors.

문학,문화 : 라티노성(Latinidad) 논의의 사례와 의미 -라틴 음악을 중심으로-

이은아 ( Eun A Lee ) 경희대학교 비교문화연구소 2011 비교문화연구 Vol.23 No.-

This study examines how Latinidad can be reclaimed as a site for exploring affinities of Latinos in Latin music industry, especially from the 90s. By looking at sites where Latinidad is constituted, such as the case of Jennifer Lopez becoming Selena, it intends to suggest that the concept can be deployed as a political bridge to connect latinos. And by examining Cuban-American artists` self identification in Latin Grammy Awards, it reveals that the latin music business definitions of Latinidad is coded differently for them as ``Caribbean`` to erase a natural resonance of Cuba. In addition, by dealing with Shakira`s somewhat contradictory representation of Colombianidad, the study argues that Latinidad serves as a social construct and newly emerges as a convenient interstitial place between the Latin American and the US Latino. Shakira`s case serves to show how the transnational trends of latin music contribute to create a simultaneous sense of Latinidad and Colombianidad. Focusing on the commercial significance of understanding of what latino is or should be, this paper aims to interrogate current understandings of Latinidad in the realm of latin music and popular culture.
