연구배경: 흡연은 많은 질병과 사망의 가장 중요한 원인이나 니코틴의존성으로 인해 금연이 어렵고 이로 인한 사회적, 의료적 손실이 증가함에도 불구하고 개선되지 못하고 있다. 이러한 니코틴의존성 중 물리적 의존성과 독립적으로 관여할 것으로 생각되는 사회, 문화적 니코틴의존성을 알아보고자 연구하였다. 방법: 2006년 5월부터 8월까지 일개 대학병원 직원과 일개 의과대학생, 일반 대학생 및 건강 검진자들을 대상으로 KTSND-K 설문지를 이용하여 흡연에 관한 의식 조사를 시행하였다. 결과: 총 741명 중 평균 연령은 31.8±11.6세이었고, 남자는 428명(57.8%)이었다. 흡연력은 현재흡연자 102명(13.8%), 과거흡연자 95명(12.8%), 비흡연자 544명(73.4%)이었다. 흡연력에 따른 KTSND-K 총점은 현재흡연자, 과거흡연자, 비흡연자에서 각각 17.1±5.4, 14.3±5.5, 12.3±5.5로 흡연자일수록 의미 있게 높게 나타났다(p<0.001). 성별에 따른 총점의 차이는 남녀 각각 14.3±5.7, 11.7±5.4로 남성에서 유의하게 높았다(p<0.001). 그러나 현재흡연자 중 흡연 행태 및 금연 의지에 따라 각 군을 나누어 비교하였을 때 각 군간의 KTSND 총점의 차이는 보이지 않았다. 비흡연자 중 62.5%에서 간접 흡연의 피해를 느꼈으며, 간접 흡연을 경험하는 주요 장소는 주점 56.8%, 식당 32.3%, 학교 30.2%, 노래방 22.8%, 길거리 18.6% 등 공공 장소가 많았다. 결론: KTSND-K 설문지는 한국 흡연자의 니코틴의존성 중 사회적 니코틴의존성을 평가할 수 있는 유용한 방법이 될 수 있다고 생각된다. Background: Smoking is one of the most important leading causes of morbidity and mortality. Smoking habit is recognized as nicotine dependence, which consists of physical and psychosocial dependence. To evaluate social nicotine dependence, the Kano Test for Social Nicotine Dependence (KTSND) working group developed a new questionnaire, which consists of 10 questions with a total score of 30 in Japan. We examined the social nicotine dependence among healthy adults using the new KTSND questionnaire and evaluated validity of the KTSND questionnaire in Korea. Method: We applied Korean KTSND questionnaire version 2 to employees of hospital, university students and people for medical examination and promotion test. Complete data obtained from the 741 responders were analyzed. Result: The mean age of responders was 31.8 years. Among them, males were 57.8%. Current smokers, ex-smokers, and non-smokers were 13.8%, 12.8%, and 73.4% respectively. According to smoking status, the total KTSND scores of current smokers were significantly higher than those of ex-smokers, and of non-smokers (17.1±5.4 versus 14.3±5.5, and 12.3±5.5, p≤0.001). The total KTSND scores of males were higher than those of females, suggesting that males have a propensity for depending nicotine socially much more than females (14.3±5.7 and 11.7±5.4 respectively, p<0.001). Eight of ten questions produced significantly different scores among three different smoking groups. When current smokers were sub-classified by heavy smoking index (HSI) that represented physical nicotine dependence, we did not find a significant difference of KTSND score between low HSI group (<4) and high HSI group (≥4), This finding suggested that the psychosocial dependence might play a different role from physical nicotine dependence in smoking. Most of the non-smokers (62.5%) had an experience of harmful passive smoking especially in public place. Conclusion: Our study suggested that the KTSND questionnaire could be a useful method to evaluate psychosocial aspects of smoking. (Tuberc Respir Dis 2007; 62: 365-373)

This study aims to analyze how focus on form (FonF) techniques are reflected on the sixth-grade elementary school English textbooks in Korea. The subjects of the study were task activities of five sixth-grade English textbooks based on the 2015 revised curriculum, and the textbook activities were analyzed by revised criteria for task analysis used in Kim Jung-eun s (2017). Data was processed by the SPSS 12.0 program and analyzed through a chi-squared test. The results of this study show that, according to the average frequency of tasks in all textbooks, practice tasks were used approximately twice as much as the consciousness-raising tasks. The tasks in each textbook accounted for a large portion in the order of grammar practice, interpretation tasks, and grammar activities. It has been confirmed that the difference between the amount of the raising awareness task and that of the practice task in the textbooks and between the amount of the grammar exercise task and that of the grammar practice activity task is statistically significant. Therefore, it is necessary to increase consciousness-raising tasks when developing textbooks and present more diverse tasks for raising awareness.

Amid the global pandemic, the threat of bioaerosols has become a major concern. Bioaerosol control technology using photocatalysts is actively developing, and in particular, the visible-light-activated (VLA) photosensitizer dyes are attracting attention. Herein, the VLA antimicrobial performance and light durability of various photosensitizer dyes, such as crystal violet (CV) and toluidine blue O (TBO), were evaluated. The antimicrobial performances were quantitatively determined according to the concentration of dye, light intensity, and exposure time. In addition, the light durability was evaluated by tracking changes in the physicochemical properties of light exposure dyes. Our findings can be used as basic information for applying the VLA antimicrobial performance of photosensitizer dyes to bioaerosol control researches.

본 연구의 목적은 공간적 분포 특성만을 고려하고 있는 기존의 핫스팟분석에 대한 대안적인 방법으로서 공간상에서 나타나는 사건간의 인과관계를 시간영역으로까지 확장하여 동시적 분석이 가능한 시공간분석 방법을 제안하는 것이다. 분석방법으로는 먼저 지리정보시스템을 이용하여 지방중소도시인 M시의 범죄자료를 데이터화 하였고, Ripley K함수와 시공간검정통계량 분석을 통해 M시의 범죄분포 패턴을 지도화 하였다. 연구결과, 범죄위험도가 유의미하게 높은 지역들이 나타났으며, 이들 시공간적 범죄 집중지역들은 기존의 공간분포만을 고려한 범죄분포 패턴과는 다소 차이가 있음을 발견할 수 있었다. 본 연구결과는 시공간적인 범죄분포 특성에 맞는 맞춤형의 경찰 인력 배치와 배분, 그리고 치안행정 서비스 등의 조정을 위한 참고자료로서, 또한 시공간적인 집중을 보이는 이들 지역을 중심으로 물리적 환경 변화의 유도와 공간이용의 개선 효과를 통해 범죄율을 줄여나가는 범죄예방 활동 및 정책수립을 위한 기초자료로도 유용하게 활용될 수 있을 것으로 기대된다. The aim of this study is to investigate crime hotspot areas using the spatio-temporal cluster analysis which is possible to search simultaneously time range as well as space range as an alternative method of existing hotspot analysis only identifying crime occurrence distribution patterns in urban area. As for research method, first, crime data were collected from criminal registers provided by official police authority in M city, Gyeongnam and crime occurrence patterns were drafted on a map by using Geographic Information Systems(GIS). Second, by utilizing Ripley K-function and Space-Time Scan Statistics analysis, the spatio-temporal distribution of crime was examined. The results showed that the risk of crime was significantly clustered at relatively few places and the spatio-temporal clustered areas of crime were different from those predicted by existing spatial hotspot analysis such as kernel density analysis and k-means clustering analysis. Finally, it is expected that the results of this study can be not only utilized as a valuable reference data for establishing urban planning and crime prevention through environmental design(CPTED), but also made available for the allocation of police resources and the improvement of public security services.
