본 연구의 목적은 노인들의 신체활동 프로그램인 한국무용 참여가 우울감에 어떠한 영향을 미치는지를 파악하여 노인의 우울감에 대한 문제와 해결책을 제시함으로써 노인의 보다 나은 삶의 질에 관련된 노인여가복지정책과 한국무용 활성화에 필요한 기초자료를 제시하는 데 있다. 이러한 연구목적을 달성하기 위하여, 우리나라의 한국무용프로그램 참여 노인들의 우울감 변화에 대한 이론적인 내용과 한국무용을 하기 전과 후의 우울감의 변화를 실증적으로 분석하였다. 분석결과 노인들의 한국무용 참여시간이 길수록, 만족도가 높을수록 우울감의 변화 정도가 더 커지는 것으로 나타났다. 또한 한국무용의 참여빈도가 많아질수록, 참여기간이 길수록, 숙련도가 높아질수록 노인의 우울감 변화 정도에 영향을 주지 않는 것으로 나타났다.

Radon (222Rn) gas is a main source of ionizing radiation of natural origin. It typically moves up through the ground to the air above and into building or home through cracks and other holes in the foundation. Significantly, the Surgeon General has warned that radon is the second leading cause of lung cancer in the United States today. This survey covers the determination of indoor radon concentrations at home from 2013 to 2014 in some areas of Gangwondo, every three months (seasonal) during one year using an alpha-track detector. The results showed that the annual average concentration of indoor radon was 84.5 Bq/m3 (GM: 64.5 Bq/m3) at homes. Indoor radon level was the highest in winter and the lowest in summer. Geometric mean radon concentration in winter was 1.03~2.58 times higher than other seasons. The data obtained from this study provide a basis for the preparation of legal regulation and public health protection manuals in this area.

The objective of this study is to investigate indoor radon concentrations and identify influencing factors for one of the representative house type in South Korea. We surveyed 3,000 detached houses using alpha track (raduet) between November 2013 and March 2014. The Arithmetic mean radon concentration of the houses studied was 147.9 Bq/m3 (GM=106.4 Bq/m3), and the range was 11.8 to 1,936.6 Bq/m3. The Arithmetic mean radon concentration in living rooms was 134.2 Bq/m3 (GM=98.8 Bq/m3), much higher value compar with the Arithmetic mean radon concentration in bedrooms (153.0 Bq/m3). The year of constructon, basement status, ventilation frequency and heating period in a house were identified as major factors influencing indoor radon concentrations. The indoor radon concentrations in houses that were constructed prior to 1990 and that had basements were higher than those in the comparison groups. On the other hand, houses that were frequently ventilated and had a short heating period showed a tendency toward lower indoor radon concentration.

This paper proposes an educational smartphone applicaiton which usages augmented reality and GPS on a smartphone to lead a learner's experience, and which provides games on cultural properties to keep the learner's interests. The proposed educational app is based on Keller's ARCS model system. To acquire knowledge through experience by using a GPS on a smartphone, the learner solves problems on cultural properties located in which the learner stays and thus the learner can keep her/his interest and increase her attention. Also, using augmented reality gives encouragement and rewards to the learner, increases her confidence and satisfaction, and helps her/him continue learning.

Retrospective analysis was conducted on the clinical data of 38 cases of bacterial meningitis that were proven by cerebrospinal fluid culture. Each case occurred by GBS (68.4%), Pneumococcus (15.8%), E. coli (5.3%), Streptococcus mitis (5.3%), Streptococcus bovis (2.6%), and Staphylococcus xylosus (2.6%). Compared to 28 cases with normal outcome, 10 cases who died or had adverse outcomes at hospital discharge were more likely to present with coma, seizure (before or within admission, focal, status epilepticus), require pressor or ventilator support, have initial peripheral blood leukocyte count less than 4,000/mm3 or neutrophil count less than 1,000/mm3, and have hydrocephalus or cerebral infarction by brain imaging.

Prevalence of Mycoplasma pneumoniae pneumonia in preschool children has shown a recent increase and macrolideresistant Mycoplasma pneumoniae pneumonia has been reported. We investigated the clinical features of Mycoplasma pneumoniae pneumonia among children of different ages and different years for the most recent seven years. Retrospective analysis was performed on the clinical data of 735 children who were hospitalized due to Mycoplasma pneumoniae pneumonia between January 2006 and December 2012. The children were divided into three groups according to age: the A group (<3 years), B group (≥3 years and <7 years), and C group (≥7 years). In addition, the children were divided into two groups according to the year in which the disease had developed: the early period (2006 and 2007 year), and the late period (from 2010 to 2012 year). The infant group (A group) presented mainly with a shorter duration of fever and more frequent wheezing. In the late period, the interval until improvement after a macrolide was prescribed increased. Clinical features of Mycoplasma pneumoniae pneumonia differed among children of different ages, particularly between infants and school-aged children.
