The purpose of this study was to analyze the introduced contents and the nature of science on the history of science in elementary school science textbooks according to the 2009 revised curriculum. For this purpose, first of all, the frequency of contents of history of science in 8 kinds of science textbooks in elementary school is analyzed by grade cluster and content part. Analysis framework for analyzing the introduced contents on the history of science was characterized with three-dimensional combination of the context, the role and the types(Park, Lee, & Lee, 2011). Analysis framework for the nature of science on the history of science was developed by Leite(2002) and revised by Choi (2005) and Kim(2010) and complemented under one expert in science education. The results of this study are as follows: First, the frequency of contents of history of science in textbook is 26 and it were not equally distributed into science textbooks in elementary school as a result of the analysis by grade cluster and content part. Second, with three-dimensional combination framework only 13 kinds were used in all 48 different types through analyzing the textbooks. It implies that ways of introducing contents of history of science into textbooks were limited to certain types. Third, the nature elements of science were not equally distributed on the history of science in elementary school science textbooks. In conclusion, in order to understand the nature of science through the history of science and to foster scientific literacy ultimately, it implicates that it is need to present various kinds of the history of science for one theme in consideration about the grade cluster and content part. Also more multilateral approach is need to introduce equally distributed into textbooks to reflect the elements of the nature of science.

The open-channel flow with submerged vegetation shows distinct features in two separate regions, namely upper and vegetation layers. In the upper layer, the flow is akin to the open-channel flow, while the flow in the vegetation layer is relatively uniform with suppressed turbulence due to vegetation stems. This paper presents laboratory experiments to investigate the characteristics of turbulent flows and suspended sediment transport in open-channel flows with submerged vegetation. An open-channel facility, 0.5 m wide and 12 m long, was used for laboratory experiments. Various discharges were employed with depth ratios of 2~3, and wooden cylinders were used for vegetation. To make equilibrium suspension, sediment particles of median diameter of 75 ${\mu}M$ were fed until capacity condition. Laser Doppler velocimeter was used to measure instantaneous velocity, and direct sampling with vinyl tube was used to measure the concentration of suspended sediment. Using the sampled data, the mean flow and turbulence structures were provided and characteristics of suspended sediment concentration with Rouse number were presented.

The purpose of this study was to survey clinical dental hygienists for their perceived ethical dilemma and professionalism. The subjects in this study were 393 dental hygienists who randomly selected worked in dental clinics. After a survey was conducted, the collected data were analyzed with a SPSSWIN 18.0 program. The findings of the study were as follows: Dental hygienists perceived ethical dilemma scored 2.46 on a 5-point scale on average. In view of its sub-areas, the sub-areas which scored highest was 'dental hygienist with the profession'(2.62), followed by 'dental hygienist with object'(2.41) and 'dental hygienist with coworker'(2.34) in their order. Dental hygienists perceived professionalism scored 3.28 on a 5-point scale on average. In view of its sub-areas, the sub-areas which scored highest was 'sence of public service'(3.55), followed by 'autonomy'(3.42), 'reference professional group'(3.14) and 'sence of mission'(3.01) in their order. In regard to the relationship of the general characteristics to professionalism, those who were older, whose career was longer, whose education was highest and who were married were statistically significantly ahead of their counterparts in that aspect. In relation to factors affecting professionalism, longer career and higher education had a better impact on professionalism. Those factors made a 13% prediction of that.

Objectives: This study aimed to determine the effects on musculoskeletal symptoms of both social demographic features and detailed characteristics of each task category of care workers who offer visiting home-help services. And to establish the measures that can reduce musculoskeletal symptoms among care workers. Methods: This study was conducted among 192 care workers from welfare centers C and K located in city P. After participants completed the task burden checklist regarding the scale of musculoskeletal symptoms and the details of their duties, the data collected were analyzed using the SPSS 21.0 program. Results: According to the degree of observable musculoskeletal symptoms in care workers, the highest figures were observed for back and shoulder pain. Based on the results of assessing the effect of detailed task category characteristics on musculoskeletal symptoms, "helping patients eat, helping patients move, helping patients bath, and changing body positions" were found to have an effect from the physical care category, "providing physical therapy assistance, treating bedsores" from the health care category, and "cleaning and doing laundry" from the facility management category. Conclusions: Due to the high proportion of patients requiring burdensome physical labor from care workers such as moving patients who have trouble doing so on their own, helping them change positions, and so on, it is highly likely that pain will occur in the low back, which carries most of the physical weight. So, education on human epidemiological positions that can reduce overload on areas prone to pain such as the low back and shoulders is essential. Proper equipment and personnel support must be provided for dangerous tasks. Further, multidimensional social support is required consistently.

모두 4장에 걸쳐 20편의 논문이 실려 있는 "한국도자사연구"는 외형상 논문집의 체제이면서도 각각의 논문들이 종횡으로 연결돼 있어 한국도자사의 전체상 개괄을 가능케 한다는 점에서 우선 눈길을 끈다. 이와함께, 이제까지의 도자사 연구영역에서 통설로 여겨지던 것들에 대해 과감한 문제제기가 이뤄지고 있는 점도 특징으로 꼽힌다.

건축이 최근 지식경제부의 영역으로 편입되면서, 건축은 새로운 국면을 맞게 되었다. 그간 국토해양부와 문화체육부 산하에서만 다루어지던 내용위에 지식이란 측면의 중요성이 추가로 얹어지게 되었다. 따라서 그간 문화 예술, 기술 산업분야로 정의되었던 건축이 지식분야를 포함하면서 건축의 본질적 정의에 많이 가까워진 것으로 판단된다.
