This study aims to analyze how students' design work functions affect consumer attitudes and purchase intentions toward clothes designed by students, while exploring the moderating effect of price sensitivity in such a relationship. Data was acquired from 351 responses of an online questionnaire (www.sojump.com). A two-step approach was employed to analyze our hypotheses using structural equation modeling (SEM) in SPSS 22.0 and AMOS 22.0 statistical packages. First, significant empirical evidence was secured regarding the effects of design functions (assurance, fashion, camouflage, individuality, and comfort) on consumer attitudes toward clothes, which can lead to purchasing intention. Fashion, individuality, and comfort functions can enhance consumer attitude significantly, but assurance and camouflage have no significant influence. Among the functions, comfort has the greatest effect on consumer attitudes, indicating that when students market works as commodities, comfort should be highlighted in their designs. In this way, such products can draw the interest of many consumers. Second, empirical evidence showed that price sensitivity negatively moderates the association between attitude and purchase intention. Thus, design courses should be careful when setting student works' prices given consumer sensitivity. The optimization of the student works' cost structure can help minimize price sensitivity. Overall, the findings and their implications can serve as a basis for the commercial application of design curriculum works and provide feasible support for developing student design curriculum in the future.

Purpose: This study aimed to identify tasks performed by patient safety personnel using importance-performance analysis. Methods: An online survey was conducted during a mandatory educational course. The questionnaire consisted of 43 items categorized into four subscales: management of patient safety accidents, education of healthcare personnel, education of patients and guardians, and patient safety activities. Importance-performance analysis was employed to ascertain the relationship between the importance and performance of tasks conducted by patient safety personnel. Results: A total of 145 patient safety personnel participated in the survey. The perceived importance of tasks by participants averaged 3.67 out of four, while the average performance was 3.40 out of four, indicating a significant difference (t=8.04, p<.001). Activities such as collecting patient safety reports, conducting root-cause analyses, and educating new employees were identified as low-performance tasks compared to their perceived importance. Conclusion: Tasks recognized as having low importance but high performance among patient safety personnel should be addressed through increased awareness and education. Analyzing the causes of tasks with low importance and performance is crucial for recognizing their importance and implementing improvement measures.

Due to COVID19 pandemic, most of educational institutions and schools changed the traditional way of teaching to online teaching and learning using well-known Learning Management Systems (LMS) such as Moodle, Canvas, Blackboard, etc. Accordingly, LMS started to generate a large data related to students' characteristics and achievements and other course-related information. This makes it difficult to teachers to monitor students' behaviour and performance. Therefore, a need to support teachers with a tool alerting student who might be in risk based on their recorded activities and achievements in adopted LMS in the school. This paper focuses on the benefits of using recorded data in LMS platforms, specifically Moodle, to predict students' performance by analysing their behavioural data and engagement activities using data mining techniques. As part of the overall process, this study encountered the task of extracting and selecting relevant data features for predicting performance, along with designing the framework and choosing appropriate machine learning techniques. The collected data underwent pre-processing operations to remove random partitions, empty values, duplicates, and code the data. Different machine learning techniques, including k-NN, TREE, Ensembled Tree, SVM, and MLPNNs were applied to the processed data. The results showed that the MLPNNs technique outperformed other classification techniques, achieving a classification accuracy of 93%, while SVM and k-NN achieved 90% and 87% respectively. This indicates the possibility for future research to investigate incorporating other neural network methods for categorizing students using data from LMS.

골프장에서 제초와 병해충방제를 위해 농약의 사용은 필수적인 요소이다. 농약은 적절하게 관리되지 않을 경우 주변 환경과 생태계에 악영향을 초래할 수 있다. 그러나 우리나라의 경우 골프장의 농약사용에 관한 구체적인 통계나 체계적 관리방안이 없는 실정이었다. 본 논문에서는 골프장에서 사용되는 농약의 실태를 파악하고 이를 국가적 차원에서 체계적으로 관리할 수 있는 방안에 관해 조사하였다. 골프의 대중화로 인해 우리나라의 골프장은 급격히 증가하여 2011년 말 기준으로 421개소가 운영되고 있으며 이는 면적으로 $379.53km^2$이다. 이와 더불어 농약사용량도 매년 증가하고 있으며 2011년에는 216품목의 농약이 성분량 기준으로 총 118,669.4 kg이었고, 살균제(54.9%) > 살충제(24.4%) > 제초제(13.3%) > 생장조정제(0.1%) 순이었다. 2011년 골프장별 평균 농약사용량은 성분량으로 280.9 kg이였으며, 단위면적당 평균 농약사용량은 $5.4kg\;ha^{-1}$이였으나 이는 일반 농경지에서의 사용량의 50%에 해당되는 것이다. 골프장별 사용량은 $0.0-21.9kg\;ha^{-1}$ 범위로 편차가 매우 컸다. 골프장내 잔류농약성분의 검출빈도는 green > fairway, 잔디 > 토양 순이었다. 과거에는 일부 골프장에서 고독성농약을 사용하거나 검출되기도 하였으나 최근에는 사용하지도 않으며 검출되지도 않았다. 골프장의 농약사용의 실태를 파악하고 농약에 따른 환경피해를 예방하기 위해서 환경부에서는 2010년 초에 '골프장 농약 사용실태 관리시스템'(환경부 토양지하수정보시스템)을 개발하였다. 이 시스템을 통해 골프장에서의 농약사용 모니터링과 잔류 농약 검사에 관한 선진화된 관리체계를 구축하였다. 농약 잔류량 검사는 토양, 잔디 및 유출수 시료에 대해 실시하고 있고 검사시료는 골프장의 규모에 따라 결정할 수 있도록 정하였다. 우리나라는 골프장의 농약사용에 관련된 업무를 여러 부처에서 담당하다가 2009년부터 환경부로 일원화하여 추진하고 있으나 아직까지 법령과 행정규칙 등이 체계적으로 정비되지 않은 상태이다. 골프장에서의 농약사용과 관리 및 주변 생태계와 인간에 미치는 영향 등을 파악하기 위해서는 개별 골프장에 적합한 지역특이적 최적 관리방안(site-specific best management practices)이 우선적으로 마련되는 것이 바람직하며, 이는 위해서는 위해성평가의 도입이 우선적으로 이행되어야 할 것이다. 우리나라는 골프장의 농약사용 및 농약잔류량 검사, 환경오염피해에 대한 기초연구, 환경오염 저감기술 등 관련 인프라가 매우 부족한 실정이다. 따라서 향후 정부에서는 관련제도를 정비하고, 개선 발전시켜 골프장에 의한 환경피해를 최소화하여 골프장이 친환경적으로 운영될 수 있도록 지속적인 관심과 지원이 이루어져야 할 것이다.
