  • 최근 급격한 기대수명의 증가에 따라 미래 복지정책 등에 커다란 영향을 주는 장래 사망력의 정확한 예측은 중요한 이슈가 되고 있다. 사망력의 정확한 예측을 위하여 최적의 추정모형의 선택도 중요하지만 사망력에 대한 시계열 적용기간도 매우 중요한 이슈다. 이는 우리나라의 사망률 시계열이 짧고, 특히 1982년 이전 자료가 다소 불완전해서 이에 대한 고려가 필수적이기 때문이다. 본 논문에서는 우리나라 사망력 시계열을 기간에 따라 2개의 그룹(1976~2005년, 1983~2005년)으로 나누어서, 남녀별로 LC모형과 LC 코호트효과 확장모형에 대한 모수 추정값, 사망력지수와 코호트지수의 모형화 및 예측, 장래 기대수명의 예측 적합력을 각각 분석한 후 향후에 장래 기대수명 추계시 고려할 시사점을 제시하고자 한다.

  • Purpose: The purpose was to investigate the factors influencing the alcohol consumption behavior of adolescents to provide basic data for a nursing intervention program to improve health management and prohibit alcohol consumption. Method: The subjects were 306 university students, living in K city in Chungnam province from April 1 to 20th, 2002. The instruments used were the alcohol consumption behavior scale, that is the drinking intensity score, and developed by Shin(1998)'s scale of drinking problem, refusal self-efficacy scale by Aas et. al.(1995), alcohol expectancy by Goldman et. al. (1989), TPQ scale by Cloninger(1991), depression scale by Zung(1974), family cohesion scale by Olson et. al. (1983). The data were analyzed using descriptive statistics, Pearson correlation coefficient, t-test, ANOVA, and stepwise multiple regression by using SPSS & SAS program. Results: The multiple regression analysis revealed that the most powerful predictor of alcohol consumption behavior was the influence of friends (drinking everyday) (17.0%). A combination of alcohol expectancy (8.0%), influence of friends (4.0%), father's influence (2.0%), depression(2.0%), refusal self-efficacy (1.0%), personality of harm avoidance(1.0%), and monthly pocket money (2.0%) accounted for 38.6% of the variance in alcohol consumption behavior. Conclusion: From the results, we recommend to use the database that develops nursing intervention program for decreasing the alcohol consumption behavior including the influencing factors in university students.

  • The purpose of this study is to apply the expectancy disconfirmation model to consumer post-purchase behavior toward fast fashion brands. This study incorporated repurchase intention as a result of consumer satisfaction. It was hypothesized that consumer satisfaction, which is influenced by expectation, perceived performance, and disconfirmation, influences repurchase intention. It was also hypothesized that expectation influences performance. This study examined the brands and prices of the most recent purchases of fast fashion and also examined whether the purchases were planned or unplanned. The hypothesized path was tested and the relative influences of instrumental and symbolic performance on satisfaction were identified. Data were collected from questionnaires answered by 344 university students who were selected by convenience sampling. The results were as follows: 1) Purchased brands were, in the order of frequency of purchase, Uniqlo, Zara, H&M, and Forever21, followed by domestic brands, 8seconds, Spao, and Mixxo. The frequency of unplanned purchase was more than twice higher than planned purchase. 2) Based on expectation and performance, dissatisfactory group was larger than satisfactory group, which were 35.8% and 24.7% respectively. 3) It was revealed from the expectancy disconfirmation model analysis that expectation and performance had positive influence, but cognitive dissonance had negative influence on satisfaction. Satisfaction had significant influence on repurchase intention. The path analysis showed that all hypothesized path coefficients were significant. The results suggest some effective marketing strategies for marketers in the fast fashion industry.

  • Objectives: The purpose of this study was to propose contents of a curriculum and training program for dental hygienists as medical professionals by surveying the opinions of clinical dental hygienists and dental hygiene professors. Methods: The subjects were 192 clinical dental hygienists and 193 dental hygiene professors. They answered questionnaires that consisted of grading each task based on its importance: a) for dental hygiene students to learn, b) to perform autonomously in clinical practice, and c) the expectancy of the task to change when dental hygienists become medical professionals. Data analysis was performed using an independent sample T test to capture differences between clinical dental hygienists and dental hygiene professors. The terms in the answers of open-ended questionnaires were extracted. We used R 3.5.0, R Recommender, and Wordcloud software packages. Results: Calculus removal had the highest scores for dental hygiene students to learn and expectancy to change when dental hygienists become medical professionals. Physiotherapy of temporomandibular disorders (TMD), planning, performing, and assessment of community oral health programs had the lowest scores in autonomy in clinical practice. The dental hygiene professors gave higher scores in most of the tasks for dental hygiene students to learn, autonomy in clinical practice, and expectancy to change, than did clinical dental hygienists. Cardiopulmonary resuscitation (CPR), job ethics, and communication were the most frequently mentioned terms in the training as medical professionals program contents. Conclusions: In the future, it will be necessary to study the curriculum to improve the proficiency of dental hygienists as medical professionals.

  • Objectives: The purpose of this study was to examine the perception of dental hospital accreditation and the awareness and practice of infection control in dental hygienists. Methods: A self-reported questionnaire was completed by 238 dental hygienists working at dental hospitals in Gwangju Jeonnam and analyzed from October 24, 2016 to September 22, 2017. Data were analyzed with the independent t-test, one-way analysis of variance, Pearson's correlation analysis, and multiple regression analysis using the Statistical Package for the Social Sciences software, version 21.0. Results: Compared to non-accredited dental hospitals, all three variables were high for accredited dental hospitals. In accredited dental hospitals, healthcare accreditation expectancy effects correlated to awareness (r=0.407) and practice (r=0.533) of infection control, and awareness of infection control correlated to its practice (r=0.725). In non-accredited dental hospitals, healthcare accreditation expectancy effects correlated to awareness of infection control (r=0.239), and awareness of infection control correlated to its practice (r=0.481). Accredited dental hospitals showed healthcare accreditation expectancy effects (${\beta}=0.258$) and awareness of infection control (${\beta}=0.556$), and non-accredited dental hospitals were influenced by the number of employees (${\beta}=0.567$) and awareness of infection control (${\beta}=0.376$). Conclusions: It is necessary to develop efficient and systematic infection control programs to improve the awareness and practice of infection control in dental hygienists and patient's safety in the clinical field.

  • 지난 50여 년 동안 우리나라의 사망률 감소 패턴에 대한 탐색적 연구에 의하면 연령별 사망률이 모든 연령에서 감소했지만, 특정한 사망률이 개선되고 있는 패턴은 연령과 기간에 따라 다르다는 것을 알 수 있다. 여자가 남자보다 사망률 개선이 뚜렷하고 특히 시간이 지나면서 특정그룹에서의 사망률 개선이 두드러짐에 따라 전반적으로 사망 시간 추세에 구조적인 변화가 존재함을 확인하였다. 이에 본 연구에서는 우리나라 여자 사망률 자료를 이용하여 미래 사망률 예측을 위해 코호트 효과를 고려한 다양한 확률적 사망률 모형을 살펴보았다. 또한 분석 결과를 바탕으로 2067년까지 연령별 사망률과 예측기대수명을 작성하고 통계청(KOSIS)에서 제공하는 장래 연령별 사망률과 기대수명과 비교하였다. 자료이용기간에 따라 최적의 모형이 상이하나 적합력과 예측력을 전반적으로 고려했을 때 우리나라 여자 사망률은 코호트 효과를 고려한 PLAT 모형이 적절하다 볼 수 있을 것이다.
