The purpose of the study is to identify the barriers to using mobile health applications based on the Diffusion of Innovations Theory. The study employed a purposive sampling to recruit college students who were non-adopters or rejecters. The study participants were a total of 44 students, who consist of 32 males and 12 females, and paper-based interviews were conducted. The findings of the study indicated that attributes such as relative advantages, complexity, trialability and observability were not considerable factors of impeding the adoption or continuous use of health applications, whereas relative disadvantages and compatibility were. The study suggests that health application developers and service providers minimize relative disadvantages and enhance compatibility of the innovation with consumers' life styles, rather than try to improve relative advantages and complexity, to more effectively encourage non-adopters to try and maintain using the innovation.

병원 근로자의 VDT 자각 증상에 대한 선행연구를 보면 대부분이 간호사 관련 직종으로 한정되어 있고, 방사선사에 대한 연구는 수행되지 않았다. 본 연구는 2009년 10월 15일부터 11월 2일까지 대전광역시에 소재하고 있는 종합병원에 VDT 작업을 시행하는 보험심사, 원무, 의무기록, 전산, 행정부서 근무자와 방사선사를 대상으로 구조화된 설문지를 활용하여 분석하였다. VDT 증후군 자각 증상 점수를 종속변수로 한 다중선형회귀 분석 결과 관련요인으로 안관련 증상에 영향을 미치는 요인을 보면 성별, 건강염려, 일상생활 방해이며, 전신증상은 운동, 스트레스, 건강상태 인지 관련, 근골격 증상에서는 임상경력 6-10년, 대인관계, 건강상태 인지 관련 건강염려와 일상생활 방해로 나타났으며, 통계적으로 유의한 차이를 보였다. 피부 증상으로는 연령 20-29세, 결혼여부, 식습관, 건강상태 인지 관련 소화 정도와 일상생활 방해로 나타났으며, 심리 증상으로는 성별, 결혼 여부, 스트레스, 소화 정도, 일상생활 방해로 나타났으며, 통계적으로 유의한 차이를 보였다. 타부서 근로자와 방사선사의 VDT 증후군 자각점수 차이가 크게 나타나지 않았으며, 이는 방사선사의 업무가 VDT 환경으로 변함으로써 VDT 증후군 자각 증상이 일어날 수 있다는 것을 나타내는 것이다. 이는 정기적인 순환근무를 시행함으로써 VDT 환경에 지속적인 노출을 피하는 것이 예방 대책이라 할 수 있다.

The Purpose of this study was to discover the factors which motivate academic library users to use chat reference service and which demotivate academic library users to use chat reference service. To achieve the study purposes, this study conducted interview with the selected participants (Information Studies graduate students at Florida State University(FSU)) through email in April and May 2007. This study found that 1) convenience, 2) anonymity, and 3) inexpensiveness of the service served as incentives(motivators) for chat reference service consumers to use the service. On the other hand, chat reference service consumers mentioned the following factors as obstacles (demotivators) for using the service: 1) waiting time, 2) accessibility, 3) interface design, and 4) difficulties with expressing themselves in a virtual space.

This study was conducted at the Civilian Controlled Zone(CCZ) in the Cherowon from February to March 2004 to investigate the reaction to the vehicles of Red-crowned Cranes(RCC) and White-naped Cranes(WNC) and trade-off of the vehicle interruption with food resources. The for-aging distance from the road of WNC was much closer than that of RCC. The large flocks of cranes' average feeding distance from the road was farther than small flocks of cranes in both species. Cranes showed the reaction, such as alert, walking, running and flying against the vehicle stop and were more sensitive as they were close to the road. The reacting time to the stopping vehicle were reduced as it was farther from the road. The distance of about 250m was a reaction threshold distance against the vehicle stop to both species. The reacting time in the same distance was not different in relation to the traffic volume, but large traffic volume tended to cause cranes to stay far away from the road and not to feed themselves near a traffic congested area. The reason cranes fed themselves on fallen rice grains in spite of the vehicular traffic interruption factor was that there was a high density of the fallen rice grains remaining at the area near a road.

This study was conducted to establish and verify a theoretical model that explains the factors and pathways influencing the psychological well-being of nurses. The subjects of this study were nurses working in four general hospitals with over 200 beds in B city and G province. The results of verifying the path coefficient of the nurses' job rotation stress showed that job rotation stress had a significant effect on challenge stress, hindrance stress, and nurses' psychological well-being, while hindrance stress had a negative effect on nurses' psychological well-being. Nurses' job rotation stress had direct effects on challenge stress, hindrance stress, and psychological well-being. Hindrance stress had a direct effect on psychological well-being. In addition, nurses' job rotation stress had an indirect effect on psychological well-being through hindrance stress. Nurses who experienced job rotation showed challenge and hindrance stress. Since hindrance stress interferes with the psychological well-being of nurses, it is necessary to manage stress and make efforts in the nursing organization. Therefore, nursing organizations should establish a positive organizational environment and develop systematic strategies so that job rotation can be a challenging stress factor for nurses.

ADHD 아동의 주의장애 원인이 반응 결정에서의 억제의 미숙인지, 전반적인 주의 기능의 미숙인지 알아보기 정상아동과 ADHD 아동을 대상으로 flanker 과제를 실시하였다. 실험 1 에서는 방해자극과 목표자극의 일치 (3: 일치, 불일치, 중립), 방해자극과 목표자극의 SO (3: -100, 0, 100 ms), 집단 (2; 정상, ADHD)의 3 요인 실험을 실시하였다. 정상아와 ADHD 아동간에 반응시간에서는 차이가 없었다. 그러나 정상아동에 비해 ADHD 아동이 부정확 반응을 더 많이 하였다. 특히 방해자극이 100 ms 먼저 제시되기 시작하는 SOA -100 ms 조건에서 두 집단의 차이가 크게 나타났다. 이 결과가 반응결정 단계에서의 억제에서 비롯되는 것인지 알아보기 위해 실험 2 에서는 목표자극의 반응 set(좌, 우)에 포함되지 않는 방해자극(상, 하로향함)을 제시하는 무관련조건을 추가하여 실험을 실시하였다. 실험 1 과 같이 불일치조건에서는 정상아동에 비해 ADHD 아동이 오반응을 더 많이 산출하였다. 그러나 무관련조건에서는 정상아와 ADHD 아동 간에 오반응에서 차이가 없었다. 즉 두 집단 모두에서 중립조건보다 무관련 조건에서 반응시간은 길었으나, 오반응에서는 차이가 없었다. 즉 정상아와 ADHD 아동 모두 전반적인 주의에서는 차이가 없다는 것을 시사하였다. 두 실험의 결과는 정상아에 비해 ADHD 아동이 반응 결정 단계에서의 억제에서 차이가 나는 것을 시사하는 것으로 해석되었다.

The purpose of current study is to investigate university students' attitudes toward prostitutes and factors affecting their attitudes. Based on previous research, age, grade, major, gender, religion, religious faith, watching pornography, prostitution experience, empathy level, anti-prostitution/anti-rape /human right education and gender equality level were constructed as independent variables. Using self-administered survey method, 502 students participated in survey. Research results indicated that average of respondents' attitudes toward prostitutes 4.19 was higher than median value(3). Results of multiple regression revealed that a male student, a social welfare and theology major student, a respondent with lower social-economic status, a respondent with higher level of empathy, and gender equality is more likely to demonstrate more supportive and positive attitude toward prostitute. Based on research results, developing programs aimed at enhancing empathy and gender equality, and implementing character education and prostitution/sexual violence prevention program were provided as policy implications.

한 시스템 내에 GAOs와 PAOs의 공존은 몇몇의 kinetic과 화학양론적 함축을 가지고 있다. 이는 유기물질 획득율의 측면에서 PAOs가 혐기성 단계에서 GAOs보다 kinetic적으로 유리하다고 제안되고 혐기조건에서 GAOs와 PAOs는 이용 가능한 기질에 대해 경쟁한다. PAOs에 있는 저장과는 달리, GAOs에서 glycogen의 생성은 과잉 인을 요구하지 않는다. 그러므로 GAOs는 성장에 필요한 이상의 인을 섭취하지 않는다. 결과적으로 EBPR 시스템의 방해요인이 될 수 있다. 이용 가능한 기질의 농도는 PAOs와 GAOs의 경쟁구도에 상당한 영향을 미치는 이는 전체 EBPR 시스템 내에서 인 제거 효율에 영향을 미칠 수 있다.

In this study we developed monosyllable lists for articulation test for Korean. We sampled 103, 581 colloquial monosyllables, applied them to five selection rules that based on Korean linguistic characterisitcs, and finally constructed five different lists with fifity monosyllables. The validity test using the monaural impairment factors such as S/N ratio and cut-off frequency showed that articulation scores were changed systematically according to the level of impairment factors. In addition, we investigated the effect of azimuth of a single competing sound source upon articulation scores. The syllables were always reproduced by the loudspeaker in front of the subject, while Hoth noise( -5dB/oct) were reproduced by the loudspeaker with varying azimuth around subject. The result indicated that the articulation depended on the azimuth of competing sound sources and no significant differences among lists were found in all experimental conditions.
