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.

This study was conducted to reveal central phenomena regarding the experiences of play therapists in the post-COVID-19 era. For this purpose, one semi-structured interview approximately 100 to 120 minutes in length was conducted with five experienced play therapists from Aug to Oct 2023. Based on the transcripts, the participants' experiences were analyzed according to the research method suggested by Giorgi (2004). The essence of the experience finally derived were divided into 5 structures and 23 subcategories. The five themes are ‘Experiencing a crisis’, ‘Struggling’, ‘Having the opportunity for transition’, ‘Recognizing the impact’, and ‘Adapting to the environment’. This study is significant in that it reveals the essential meaning of the experience of play therapists in the post-COVID-19 era and presents discussion points to prepare for pandemic situations in the play therapy field.

The middle school subjects were 65.8% girls and 34.2% boys. Seniors were most abundant at 56.3%. The most abundant location was Gyeonggi-do (54.7%), and 69.3% of subjects were living with 4?5 family members. Approximately 56% of the mothers had graduated from high school, and 58.1% were unemployed. The mother most often prepared the food (78.4%), fish was eaten mostly in the home, and taste was the most important factor (62.6%). The preferred home food menu was fish because it is healthy, and the main cause for disliking the school meal service was poor quality dishes compared to a home cooked meal. The acceptance and type of fish were proportional. Rice was the most favored dish to eat with fish and scored 3.97, the highest rank. Approximately 50% answered that fish was nutritious, and a significant difference was observed regarding the mother`s educational background (p<0.05). Students who never had a lecture about fish answered that fish was not nutritious, which showed a significant difference with education (p<0.05). Approximately 44% of students ate fish 2?3 times per week, and male students showed a significantly higher intake of fish than female students (p<0.05). The poorly educated disliked fish the most, and the higher frequency intake of fish resulted in a significantly higher percentile (p<0.001).

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.

본 연구에서는 공융용매와 효소 전처리를 통해 셀룰로오스 나노피브릴을 제조하였으며 처리 조건에 따른 특성을 비교하였다. Choline chloride (ChCl)과 lactic acid (LA)를 1/1 (molar ratio) 비율로 혼합시킨 후, 80℃조건에서 투명해질 때 까지 교반하여 공융용매를 제조하였다. 제조된 공용용매 ChCl/LA (1/1) (98 g)에 소나무 목분(2 g)을 첨가시킨 후 130℃에서 2, 3, 6h 동안 반응을 진행하였다. 공융용매 불용성 잔사를 아세테이트 버퍼(pH 5.0)에 2 %(w/w) 농도로 현탁시켰다. 그 후, 고형분 대비 1%의 acremonium 셀룰레이스를 첨가하여 50℃에서 48h 동안 효소처리를 실시하였다. 공융용매 및 효소처리된 샘플을 고압호모지나이저에 투입시킨 후 20,000psi 압력으로 반복해섬하여 셀룰로오스 나노피브릴(cellulose nanofibril, CNF)를 제조하였다. CNF의 형태학적 특성 관찰 결과, 공융용매 처리 시간이 증가함에 따라 평균 섬유 직경이 감소하였으며, 여수시간이 증가하였다. 또한, 효소전처리된 CNF는 보다 작은 섬유직경과 균일한 형태학적 특성을 보였으며, 우수한 보수도를 보였다.

본 연구는 유통업계의 화두로 떠오르고 있는 옴니채널 소비자를 대상으로 쇼핑혜택 추구가 만족에 미치는 영향을 알아보고자 하였다. 또한 온라인 구매와 오프라인 구매에 따라 쇼핑혜택 추구가 만족에 미치는 영향에 차이가 있는지 알아보고자 하였다. 본 연구는 서울 및 수도권에 거주하는 20~30대의 남녀로, 옴니채널을 이용해 의류제품을 쇼핑 및 구매한 경험이 있는 소비자를 대상으로 온라인 설문조사를 실시하였으며, 최종적으로는 226명을 분석에 사용하였다. 분석은 SPSS 18.0을 활용하여 각 변수의 하위차원을 살펴보고, 신뢰도분석, 빈도분석을 실시하였다. 나아가 탐색적 요인분석을 근거로 AMOS 18.0 프로그램을 통해 측정 모형의 타당성 분석을 위한 확인적 요인분석을 실시하였으며, 최종적으로 구조방정식 모형을 통한 경로분석을 실시하여 각 변수 간의 연관성에 대해 분석하였다. 경로분석에 앞서 실시한 탐색적 요인분석 결과, 쇼핑혜택 추구는 ‘편의성’, ‘경제성’, ‘절약성’, ‘관계성’의 4개의 요인으로 도출되었으며, 만족은 1개의 요인으로 도출되었다. 경로분석 결과는 다음과 같다. 쇼핑혜택 추구가 만족에 미치는 영향을 보면 편리성, 경제성, 관계성 혜택은 만족에 영향을 미치는 것으로 나타났으며, 절약성은 만족에 영향을 미치지 않는 것으로 나타났다. 온라인 구매와 오프라인 구매에 따라 조절효과를 살펴본 결과, 온라인 구매자는 경제성 추구가 만족에 영향을 미치고, 오프라인 구매자는 편리성과 관계성 추구가 만족에 영향을 미치는 것으로 나타났다. 본 연구는 분석결과를 통해 유통업계에서 대두되고 있는 옴니채널의 적절한 유통전략수립에 실무적인 시사점을 주고자 하였다. The Omni-Channel consumers rise as the important target consumers in the fashion retailing industry. The purpose of this study is to examine the effects of the Pursuit of Omni-Channel Shopping Benefits on Satisfaction. In addition, the study analyzes the differences between online and offline purchases in regard to the effects of the Pursuit of Shopping Benefits on Satisfaction. An online survey was performed targeting male and female consumers aged between 20 and 30, living in Seoul and the capital area, having the experience of Omni-Channel shopping and purchasing Clothing products in the previous six months. A total of 226 consumers were used for the final analysis. Sub-levels of each variable were examined using SPSS 18.0, and then reliability analysis and frequency analysis were conducted. In addition, based on exploratory factor analysis, confirmatory factor analysis was conducted using AMOS 18.0 for validity analysis of the measurement model, and then path analysis was conducted through structural equation modeling to analyze the relations between variables. As a result of exploratory factor analysis conducted prior to path analysis, the Pursuit of Shopping Benefits consisted of four factors, ‘convenience’, ‘economic feasibility’, ‘conservation’, and ‘relationship.’ Satisfaction led to one factor. The results of path analysis can be summarized as below. As a result of analyzing the effects of Shopping Benefits on Satisfaction, pursuit of convenience, economic feasibility, and relationship benefits significantly influenced satisfaction, while pursuit of conservation had no effects on Satisfaction. For online purchasers, pursuit of economic feasibility and conservation benefits influenced Satisfaction. In the meanwhile, for offline purchasers, pursuit of convenience and relationship benefits influenced satisfaction. The study results are expected not only to contribute to providing practical implications for establishment of appropriate distribution strategies for Omni-Channel being highlighted in the distribution industry.
