The purpose of this study was to analyze risk of falls between elderly people and college students. The subjects of this study were 25 people aged 70 years or older and 17 college students located in Asan. We measured sensory, integrated balance, nervous, musculoskeletal system and HQR by FRA system (Inbody, Korea). The results of measurement showed significant differences in sensory system (p<.01), integrated balance (p<.001), nervous system (p<.001), and musculoskeletal system (p<.001) between groups. These results suggest that aging makes difference of function of these systems. In our view, counterplans need to be implemented, including exercise intervention to prevent decreases of fall risk,

Tricholoma matsutake, an ectomycorrhiza that has mutual relationships with the rootlet of Pinus denisflora, forms a fruiting body that serves as a valuable food in Asia. However, the artificial culture of this fungus has not been successful. Soil fungi, including T. matsutake, coexist with many other microorganisms and plants; therefore, complex microbial communities have an influence on the fruiting body formation of T. matsutake. Here, we report on the structures of fungal communities associated with the fairy ring of T. matsutake through the pyrosequencing method. Soil samples were collected inside the fairy ring zone, in the fairy ring zone, and outside the fairy ring zone. A total of 37,125 sequencing reads were obtained and 728 to 1,962 operational taxonomic units (OTUs) were observed in the sampling zones. The fairy ring zone had the lowest OTUs and the lowest fungal diversity of all sampling zones. The number of OTUs and fungal taxa inside and outside the fairy ring zone was, respectively, about 2 times and 1.5 times higher than the fairy ring. Taxonomic analysis showed that each sampling zone has different fungal communities. In particular, out of 209 genera total, 6 genera in the fairy ring zone, such as Hemimycena, were uniquely present and 31 genera, such as Mycena, Boletopsis, and Repetophragma, were specifically absent. The results of metagenomic analysis based on the pyrosequencing indicate a decrease of fungal communities in the fairy ring zone and changes of fungal communities depending on the fairy ring growth of T. matsutake.

The purpose of this study is to develop an A-STEAM program using the Camera Obscura. The starting point of this study is the problems which students can encounter in real-life and it is designed to enable students to establish a research project. to integrate science, technology, engineering, and mathematics with main focus being art, and to explore all the avenues of expression using the Camera Obscura. In doing so, this study proposes possibilities of enhancement of students abilities to solve the problems and the development of artistic sensibilities. The process of developing the A-STEAM Program for art as a subject follows the PDIE process model by Jinsoo Kim. This study leaves the practice and evaluation as follow-up research and develops the teaching-learning process agenda, the paper for students' activities. and the materials for teachers' guidance by reflecting on the aspects of circumstantiation, creative design, and emotional touch. 본 논문의 목적은 카메라 옵스큐라를 이용한 미술중심 융합인재교육을 위한 수업자료의 개발에 있다. 이를 위하여 본 연구는 초둥학교 5, 6학년의 미술교과서 '관찰 표현' 단원을 재구성하고 학생자신이 실제 상황에서 부딪힐 수 있는 문제를 출발점으로 삼아 학생 스스로 과제를 설정하도록 하였다. 또한 카메라 옵스큐라를 이용한 표현 및 탐구 활동을 통해 미술 중심의 과학, 기술, 공학, 수학의 연계를 시도하였으며 시행착오를 거치는 가운데 탐구 활동을 통하여 학습자의 창의적 문제해결력과 예술적 감수성 발달의 가능성을 제시하였다. 수업자료 개발 과정은 김진수 (2012)의 초ㆍ중둥학교 STEAM 교육 수업자료 개발을 위한 PDIE 절차 모형을 따라 미술 교과용 A-STEAM 수업자료를 개발하였으며, 실행과 평가 단계는 후속 연구로 계획하고 각 차시별로 STEAM 학습 준거인 상황 제시, 창의적 설계, 감성적 체험의 요소를 반영하여 교수ㆍ학습 과정안과 학생 활동지, 교사용 자료를 개발하였다.

The purpose of this study was to investigate the association of alcohol drinking and the practices of dietary guidelines among university students in Chungbuk. Questionnaires were distributed to 351 university students and 348 (203 males and 145 females) were collected from May 21 to June 28, 2012. "Soju" was the most frequently consumed alcohol by university students. As for drinking amount, 32.7% of the students drank "ten glasses of soju or more" at one time. The frequency and the amount of drinking were significantly greater in male students than female students. While many students practiced "handling food hygienically when cooking" and "choosing clean ones when purchasing food or dining out", less students practiced "controlling energy consumption according to the activity level" and "removing fat when consuming meat." Those who drank four times per week or more responded a lower rate of practice than those who drank less frequently. As for drinking motive, those who drank "habitually" also recorded a lower rate of practice than those who drank "to fit in the mood." In conclusion, alcohol drinking had negative influences on the dietary practice of university students. Campaigns or nutrition education should be designed to help to establish a healthy drinking culture in university

In structure, Efficiency of structure itself and operation efficiency are reduced by the noise radiated from vibration. In this paper, The vibration of plate and its sound radiation are studied. The measured value of odd mode is not corresponded to the theoratical value because its nodal lines pass through the excitation point. But, the measured value of even mode is corresponded to theoratical value. When the plate was excited by frenquency with two modes, the very complexed sound-radiation-mode was observed due to the coupling effect of two modes.

고체내에서의 Phonon-Phonon 상호작용이 비열에 미치는 영향

The Debye theory of specific heat has proved to be very useful (Sutton, 1955. Betts, 1956. Joshi 1961) because it is a single-parameter theory which describes the observations remarkable well. In the Debye theory of specific heat, he has confined his attention to the "harmonic" term in the expansion of the potential energy of interaction between the ions. In this paper we considered "anharmonic" term due to phonon-phonon interaction.

In order to develop a confident sampling technique, we designed and constructed a 6-port manifold MFC sampling system for collecting gaseous pollutants in air. Using this instrumentation, we tested the performance criteria of MFC system in terms of: (1) flow rate; (2) MFC-to-MFC variability: (3) tube-to-tube variability: and (4) time. It was interesting to find that the later two factors did not show any significant variations, while the former two show substantially large variations. However, as most of those variabilities are consistent enough to form systematic patterns, we were able to explain the occurrence patterns of all those MFC biases in terms of those tour major variables. The overall results of our experiment suggest that one needs to use correction factor for each MFC unit under a given flow rate to maintain optimal accuracy and precision for sampling of those pollutants.

Thyroid hemiagenesis is a rare congenital anomaly, in which one thyroid lobe fails to develop. It is reported that thyroid hemiagenesis associated with thyroid diseases such as Graves' disease, Hashimoto's thyroiditis, colloidal goiter and thyroid follicular and papillary cancer. However, Thyroid hemiagenesis associated Hashimoto's thyroiditis haven't reported in Korea. A 31-year-old female patient was clinically hypothyroid with a left-sided goiter. Hemiagenesis of right thyroid lobe indicated on 99mTc pertechnete scan and later confirmed on ultrasonography. The authors report this case with literature review.

Muscle fatigue is a symptom that decreases your muscles’ ability to perform over time. It can be associated with a state of exhaustion, often following excessive sports activity or exercise. While exercise is a common cause of muscle fatigue, this symptom can be the result of other health conditions. Muscle fatigue caused by excessive activity limits activities of daily living and difficult to maintain a stable posture. Therefore, the purpose of this study was to investigate the effect of stretching, icing, and sports massage on muscle fatigue recovery.
