이 연구의 목적은 학생들의 과학적 논증과정 평가를 위한 루브릭을 개발하는 것이다. 루브릭의 개발을 위해 과학교육에서의 논증과정과 관련된 문헌의 분석을 통해 루브릭의 개발 절차및 평가의 범주를 도출하였다. 루브릭 개발의 일반적인 절차를 따라서 논증과정 평가의 기준을 형식, 내용, 태도의 세 가지 범주를 문헌을 통해 도출하였다. 형식의 범주에는 전체의 구성, 주장, 근거, 결론의 하위 기능으로 세분화하였고, 내용의 범주에는 이해, 신빙성, 추론으로 하위 기능을 세분하였으며, 태도의 범주에는 참여도와 개방성을 하위 기능으로 정하였다. 이렇게 구성된 각각의 하위기능의 평가에 대한 기준을 구체적인 5단계로 제시하였다. 문헌 연구를 토대로 개발된 평가 루브릭은 과학 교육 전문가 1인과 동료 연구자들의 정기적인 세미나를 통해 점검 받았다. 개발된 초기의 루브릭은 과학교육 전문가 4인에게 의뢰하여 문제점 및 개선점에 대한 검증을 받아 다시 수정되었으며, 최종 완성된 루브릭은 과학교육 전문가 4인에게 타당도를 검증받아 내용타당도지수 0.96으로 높게 나타났다. 개발된 루브릭을 통해 학생들의 논증과정에 대한 이해를 높일 수있고, 논증과정 프로그램 개발과 논증과정 평가를 위한 기준으로 활용이 가능할 것이다.

Objective: The Job Demand & Resources model suggests work characteristics are related to mental well-being and work engagement. Previous work describes the development of a combined construct 'engaged well-being at work' (EWB). To what extent changes in measures of this construct are responsive to changes in job demands and resources or associated with changes in job-related attitudes has not been established. Methods: Longitudinal employee-level data from three waves (German Linked Personnel Panel) were used. Logistic and linear fixed effects regression analyses explored longitudinal associations between changes in EWB for participants over a three-year period with changes in job demands and resources and job-related attitudes (job commitment, satisfaction, and turnover intentions). Results: While job resources were associated with increased odds for a change into a healthier and/or more engaged category of EWB, job demands reduced them. Job resources were more strongly related to higher EWB (OR_range = 1.22 - 1.61) than job demands (OR_range = 0.79 - 0.96). Especially psychological job demands showed negative associations with improved EWB (OR = 0.79). A change from the least desirable category 'disengaged strain' to any other category of EWB was associated with greater odds by up to 20.6 % for increased commitment and job satisfaction and lower odds for turnover intentions. Discussion: Improving work characteristics, especially job resources, could increase employees' EWB, emphasizing the importance of job characteristics for a healthy workplace. Because EWB seems to be associated with job attitudes, an improvement of this indicator would be relevant for employees and employers.

Hepatitis A (HA) is an acute infectious disease of the liver caused by the Hepatitis A virus (HAV). In acute HA, the presence of anti-HAV IgM is detectable and about 3 weeks after exposure, its titre increases over 4 to 6 weeks. Anti-HAV IgG is detectable within a few days of the onset of symptoms. IgG antibodies continue to last for years after infection and provide lifelong immunity to the host. This study was performed to investigate the current seroprevalence of anti-HAV antibodies in Jeonbuk province, South Korea. A total of 591 (male 322, female 269) serum samples were collected in July 2011 to June 2012. We tested the antibodies of anti-HAV IgG and IgM using a Modular E170 (Roche Diagnostics, Germany), and analysed the serum alanine aminotransferase (ALT) levels by HITACH 7600-100 (HITACH, Japan). The overall seroprevalence of anti-HAV IgG was 84.6% (500/591), and the rate of females (85.9%) was higher than males (83.5%). According to the decade of age, seroprevalence of anti-HAV IgG were as follows; 68.8% (11/16) in the under 10 years old category, 100% (19/19) in the 10~19 category, 96% (48/50) in the 20~29 category, 83.6% (56/67) in the 30~39 category, 84.3% (123/146) in the 40~49 category, 83.3% (135/162) in the 50~59 category, 83.1% (54/65) in the 60~69 category, 78.1% (32/41) in the 70~79 category, and 88% (22/25) in the over 80 category. Total seroprevalence of anti-HAV IgM was 3.4% (20/591), and according to gender, the seroprevalence of male (3.1%) was very similar to that of female (3.7%). Through this study, we know that the seroprevalence of anti-HAV antibody in north-west Jeonbuk province, South Korea, was high. Only children under the age of 10 remain susceptible to HAV infection. Vaccination against HAV is not needed at the present time for the people of Jeonbuk province, South Korea, but a vaccination should be recommended and the improvement in sanitary conditions and personal hygiene should be highlighted.

토양침식은 산악지역에서 산림조성에 중요한 문제를 일으키며 비옥한 토양을 침식시켜 식생의 성장을 저해시키며 인도에서 수집한 자료와 GIS를 이용하여 인도의 서부산맥 모야유역의 토양침식을 분석하였다. 주제도의 레이어로 산림, 지형경사, 배수 등에 대한 자료가 사용되었으며 토양침식 지도분석에서 48%의 지역이 중간정도의 침식을 보였다. 또한 35%지역은 높은 침식을 보였으며 가장 높은 침식은 식생지역의 7%를 차지하였다. 이러한 토양침식 분석도는 유역에서의 토양침식을 방지하기 위한 대책을 수립하는데 주요한 자료가 될 것으로 판단된다.

In this article, we define a (an amply) F_δ-supplemented module in category of R-Mod. The general properties of F_δ-supplemented modules are briefly discussed. Then, concentrating on the F_δ-small submodule, we find the necessary and sufficient condition for F_δ- supplemented modules. Also, we introduce ascending chain condition for F_δ-small submodules of any module and establish a basic theorem for amply F_δ-supplemented modules by using π-projectivity.

The purpose of this study was to explore the parents and child relationship in traditional Korean society through the Korean classic novels. The Data were analyzed through latent content analysis in focusing on the parents and child relationship. Forty-six Korean classic novels written in Chosun Dynasty (from 1392 to 1910 AD) were chosen to analyze and they were represented the characteristic Confucian ideas. The sentences containing the expression of child-care and parent-child relationship were selected during intensive reading line by line and analyzed. Sixty-nine meaningful concepts were drawn out from 258 significant sentences by the similar meaning and common theme and classified as 3 categories and 11 sub-categories. The important parent-child relationship expressed in Korean traditional society were as follows: From the category of the Meaning of Child, 4 sub-categories were drawn; gift of heaven, successor of the family line, driving power of life, and rewards from the offspring. From the category of attitude to the child, 3 sub-categories were drawn; a notion of preferring a son to a daughter, close maternal-child relation, and expectation to the future of child. From the category of nurturing behavior, 4 subjects were drawn; Tae-Gyo(fetal education), affective behavior, socialization, and health management behavior. Above result helps to improve the basic understanding the relationship of parent and child in modern society. And by the understanding of child in the family, unhealthy relationship of parent and child can be prevented and furthermore family centered child health promotion can be achieved.
