옛날부터 계산을 잘하는 것이 수학적으로 우수하다고 생각해왔으며, 거의 1900년까지도 교육을 받았다는 것은 계산할 수 있다는 것을 의미하였다. 초등학교의 대부분의 시간은 덧셈, 뺄셈, 곱셈, 나눗셈을 배우는 데 투입되었다. 현재에도 초등학교의 교육과정은 기본 교육에 중점을 두어 3R's(reading, writing, arithmetic)을 강조하고 있으며, 많은 교사나 학부모들은 계산능력에 대해 지대한 관심을 가지고 있다. 1970년대의 '새 수학' 운동으로 계산력이 약화되었다는 비난이 쏟아지자 '기본에 충실하자(Back to basic)'는 운동으로 계산이 강화되기도 하였다.(중략)

This study examined the effects of physical activities using Korean dance upon the motor abilities of young children. The subjects of this study were divided into 2 groups. The first group was an experimental group (boy=12, girl=13) who participated in the Korean dance class and the other group was a comparative group (boy=11, girl=14). Experiments were performed during 18 sessions for 9 weeks. The study findings are as follows. First, physical activities using Korean dance had positive effects upon the development of basic motor abilities in young children. In terms of these basic motor abilities, movement motor ability and whole muscle operation motor ability showed significant differences between the pre-test and post-test stage in the experiment group and between the experimental and comparative groups in the post-test stage. On the other hand, in terms of non-movement motor abilities, there was a significant difference between the pre- and post-test stages for the experimental group, but no significant difference in the post-test stage for the experimental or comparative groups. Second, physical activities using Korean dance had positive effects upon the development of perceptive motor abilities in young children. In other words, in the sub-variables of perceptive motor abilities, there were significant differences between the pre- and post-test stages of the experimental group which experienced physical activities using Korean dance. In conclusion, the study findings showed that physical activities using Korean dance had positive effects upon the increase of both basic motor abilities and perceptive motor abilities in young children. Additionally, the experimental group exhibited more positive effects in the various areas of motor abilities than the comparative group.

Purpose: The purpose of this study was to determine the effects of the BeHaS exercise program on balance and walking ability in middle-aged women with knee osteoarthritis. Method: Participants were 36 patients (experimental group: 18, control group: 18) with knee osteoarthritis. Women with knee osteoarthritis in the experimental group participated in the BeHaS exercise program for 65 to 90 minutes per session twice a week for 12 weeks. Data were collected by a structured interview and measurement tool from September 1, 2005 to March 30, 2006. Descriptive statistics, such as frequency, percentages, means, SD and t-test, Chi square test were used with the SPSS Win 12.0 to analyze the data. Results: There was a significant difference between the two groups for dynamic balance, but differences in balance and walking ability were only partially supported. Conclusion: These findings indicate that the BeHaS exercise program could be a good nursing intervention for health maintenance and promotion of patients with knee osteoarthritis. Further research is needed in order to confirm these findings in elderly people with osteoarthritis.

There exist patients complaining speech problem due to dysesthesia or anesthesia following dental surgical procedure accompanied by local anesthesia in clinical setting. However, it is not clear whether sensory problems in orofacial region may have an influence on motor speech abilities. The purpose of this study was to investigate whether transitory sensory impairment of mandibular nerve by local anesthesia may influence on the motor speech abilities and thus to evaluate possibility of distorted motor speech abilities due to dysesthesia of mandibular nerve. The subjects in this study consisted of 7 men and 3 women, whose right inferior alveolar nerve, lingual nerve and long buccal nerve was anesthetized by 1.8 mL lidocaine containing 1:100,000 epinephrine. All the subjects were instructed to self estimate degree of anesthesia on the affected region and speech discomfort with VAS before anesthesia, 30 seconds, 30, 60, 90, 120 and 150 minutes after anesthesia. In order to evaluate speech problems objectively, the words and sentences suggested to be read for testing speech speed, diadochokinetic rate, intonation, tremor and articulation were recorded according to the time and evaluated using a Computerized Speech $Lab^{(R)}$. Articulation was evaluated by a speech language clinician. The results of this study indicated that subjective discomfort of speech and depth of anesthesia was increased with time until 60 minutes after anesthesia and then decreased. Degree of subjective speech discomfort was correlated with depth of anesthesia self estimated by each subject. On the while, there was no significant difference in objective assessment item including speech speed, diadochokinetic rate, intonation and tremor. There was no change in articulation related with anesthesia. Based on the results of this study, it is not thought that sensory impairment of unilateral mandibular nerve deteriorates motor speech abilities in spite of individual's complaint of speech discomfort.

People observe a lot of events in our environment and we do not have any difficulty to perceive events including speech perception. Like perception of biological motion, two main theorists have debated on speech perception. The purpose of this review article is to briefly describe speech perception and compare these two theories of speech perception. Motor theorists claim that speech perception is special to human because we both produce and perceive articulatory events that are processed by innate neuromotor commands. However, direct perception theorists claim that speech perception is not different from nonspeech perception because we only need to detect information directly like all other kinds of event. It is important to grasp the fundamental idea of how human perceive articulatory events for the convergence on speech engineering. Thus, this basic review of speech perception is expected to be able to used for AI, voice recognition technology, speech recognition system, etc.
