This study aimed to help the college students majoring in beauty to have interests and manage the functional areas of scalp and hair by accurately identifying the condition of scalp and hair and realizing the convergence management habit and subjective symptoms for the condition. The study conducted a survey on 160 beauty major college universities in their 20s living in the Jeonnam area by asking the subjects to directly write the answers. The study found that many subjects had combination type of scalps and hair problems of split ends and thin hair, and recognized that their hair was damaged. They answered that frequent dyeing and perm caused the damage and they were using the shampoo for damaged hair to prevent hair damage. Regarding the observable symptoms on scalp and hair, it was identified that self-perception was higher as the interest in scalp was high, which influenced age and sleeping time.

The purpose of this study was to examine the oral health recognition and aesthetic interest of flight attendant. The data was collected 314 flight attendant from June to July 2014 in A Airlines. Questionnaires were used to measure the levels of the health & oral health recognition, experience and requirement of oral esthetic therapy. The data was analyzed using descriptive statistics, T-test, ANOVA, Pearson's correlation, structural equating model by the PASW Statistics 18.0 program. According to the research result, oral health awareness were not healthier than general health. Oral health was an important factor to influence the external image. The flight attendant received aesthetic dental care to improve the external image. However, self-assessment results that oral health condition was significantly lower. Therefore they are required oral care practice with aesthetic dental care.

The aim of this study was to investigate the relationship between job stress and smoking behaviors among small scale manufacturing male workers. A self administered questionnaire was given to 856 male workers employed in 24 work places under 50 members of manufacturing industries. As a results, the smoking rates of small scale manufacturing male workers was 35.2%. In the results of multiple logistic regression analysis to know the relationship between job stress and smoking behaviors, the Odds ratio of the total score of Korean Occupational Stress Scale(KOSS) and its subarea(physical environment, job demand, organizational system, lack of reward and occupational climate) were significantly increased in high risk group than normal group. These results suggested that job stress may play a significant role in the smoking behaviors in the high risk group than normal group of small scale manufacturing male workers.

최근 디스플레이 기술은 급속도로 발전해 가고 있다. 디스플레이 산업의 눈부신 성장에 발맞추어 초고화질, 초고선명, 고속 구동 및 대형화 등을 포함하는 최신 기술의 디스플레이 구동이 필요하다. 이러한 요구사항을 만족하기 위해서는 각 픽셀에 영상정보를 기입하는 충전시간을 급격히 감소시켜야 하고 따라서 픽셀 트랜지스터(TFT)의 이동도는 급격히 증가해야 한다. 따라서 차세대 디스플레이 실현을 위해서 고이동도 특성을 구현 할 수 있는 신물질의 개발이 매우 중요하다. 현재 산화물박막트랜지스터는 차세대 디스플레이 실현을 위해 가장 주목받고 있으며, 실제로 산화물박막 트랜지스터의 핵심소재인 In-Ga-Zn-O(a-IGZO) 산화물의 경우 국내외에서 디스플레이에 적용되어 생산이 시작되고있다. 그러나 a-IGZO 산화물의 경우 이동도가 $5-10cm^2V{\cdot}s$ 수준이어서 향후 개발 되어질 초고해상도/고속구동 디스플레이 실현(이동도 $50cm^2V{\cdot}s$)에는 한계가 있다. 따라서 본 연구에서는 이를 해결 할 수 있는 'post-IGZO' 개발을 위해 In2O3에 Ga2O3를 조성별로 고용시켜 박막의 구조적, 전기적, 광학적 특성 및 TFT를 제작하여 특성 연구를 진행하였다. 조성은 In2O3에 Ga2O3를 7.5%~15% 도핑 하였으며, Sputtering을 이용하여 indium gallium oxide(IGO) 박막을 제작하였다. 박막은 상온 및 $300^{\circ}C$에서 증착 하였으며 증착 된 IGO 박막은 Ga=12.5% 까지는 In2O3에 Ga이 모두 고용되어 cubic In2O3 poly crystalline을 나타내는 것을 확인하였으며 Ga=15%에서 Gallium 관련 2차상이 확인되었다. Ga양이 변화함에 따라 박막의 전기적 특성이 조절 가능하였으며 이를 이용하여 IGO 박막을 30 nm 두께로 증착 하여 IGO 박막을 channel layer로 사용하는 bottom gate structured TFTs를 제작 하였다. IGO TFTs는 Ga=10%에서 on/off ratio ${\sim}10^8$, 그리고 field-effect mobility $84.8cm^2/V{\cdot}S$를 나타내며 초고화질, 초고선명 차세대 디스플레이 적용 가능성을 보여 준다.

The purpose of this study was to identify the effects of clinical nurses' emotional labor and professionalism, and verify the moderating effects of social support on nursing performance. A survey was conducted with 230 nurses working in general hospitals using self-reporting questionnaires in Seoul. It was found that the number of years in current department, professionalism, social support, and deep acting of emotional labor were affecting nursing performance. Social support perceived by clinical nurses moderates the deep acting of emotional labor and it positively influenced nursing performance. Results of this study indicate that nurse managers should focus on increasing nurses' professionalism and social support, and create working environments where nurses do more deep acting of emotional labor in order to increase nursing performance. This study contribute nurse managers to recognizing the impact of emotional labor, professionalism, and social support on nursing performance. Practical programs for increasing clinical nurses' professionalism, social support and decrease emotional labor is required to be developed in further research.

This study was conducted to evaluate a take-out food safety perception instrument that could be used by foodservice establishments. A total of 324 responses was collected via online survey, and 299 responses (92.3%) were used for the statistical analysis. Data was randomly split into two groups. Exploratory Factor Analysis (EFA) was performed on the first split-half sample (n=150) to identify a factor structure using standard principal component analysis. EFA revealed three dimensions, titled "Consumer food safety perception," "Take-out food handling," and "Elements impacting on purchase decisions." Confirmatory Factor Analysis (CFA) was performed on the remaining half sample (n=149) using Structural Equation Modeling (SEM). CFA revealed acceptable absolute model fits for three dimensions and excellent comparative model fits for the instrument. These findings propose standardized measures that can be useful in assessing the take-out food safety perception.

외부 데이터가 진료병원 Server에 저장됨에 있어서 판독을 의뢰하지 않을 경우, 대부분의 병원이 무상으로 이루어 지고 있는 상황이며 이에 외부 데이터 단순 import의 효율적인 관리를 위한 수가 적용 여부를 검토하였다. 2007년 3월부터 4월까지 서울 경기 지역의 PACS가 도입 된지 1년 이상, 병상 수 500Bed 이상의 종합 대학병원 25곳에 근무하는 각 병원의 PACS 운영실 및 PACS 관리자를 대상으로 하였다. 외부 데이터에 관한 10가지 항목의 설문지를 작성하여 각 병원의 PASC 담당자 및 관리자를 대상으로 E-mail을 이용한 자기 기입 방식, 전화를 통한 질의응답 방식으로 조사하였다. 조사된 25개의 종합 대학병원의 96%이상이 외부 데이터 단순 import를 지원하고 있었으며, 그 중 92%의 병원은 무상으로 이루어지고 있었다. 이와 같이 진행 되는 부분에 대하여 각 병원의 PACS 담당자 70% 이상이 단순 import에 대한 수가 적용의 필요성을 느끼고 있으며, 현재 많은 병원에서 단순 import의 무상 지원으로 인한 문제점을 인식하고 있었다. K병원을 기준으로 단순 import에 년간 H/W 소요 비용은 336만원이고, 년간 인건비 소요비용은 421만원이다. 또한 단순 import 한 건당 평균 데이터 size는 48MB 정도로 조사되었다. 환자 입장에서 진료에 참고자료로 사용 될 외부 데이터의 정확한 저장과 정당한 PACS 사용을 위해서는 그에 상응하는 수가가 적용 되어야 할 것이다. 보험심사평가원 급여기준에 따라 수가적용이 인정되어 의료영상 디지털화로 인한 초기의 고액 투자비용 보장과 회수를 위해 단순 Import의 수가 적용이 반드시 필요하다고 사료 된다.
