1% 가량 인간의 뇌세포를 보유한 쥐가 탄생했다는 기사가 있을 만큼 생명공학이 발달하고 있고, 의학이 발달함에 따라 난치병들도 그 치료방법을 찾아가고 있다는 반가운 소식이 종종 들린다. 그러나 그만큼 듣도 보도 못한 새로운 희귀병들이 속출하고 있고, 오랜 시간 인류에게 무서운 난치병, 암은 속시원한 치료법을 아직도 찾지 못한 채 여전히 그 위용을 떨치고 있다. 일상생활을 하며 너무나도 건강하게 살다가 그 징후가 느껴져 병원을 찾으면 이미 치료시기가 지나버리기도 하고, 정기검진을 받는 사람에게도 잦은 병으로 자리잡게 되었다. 또한 최근에는 어린 아이들에게도 소아암이라는 이름 아래 예외없이 발병률를 보이고 있다. 먹을거리의 오염과 바쁜 일상 속에서 그 누구에게나 찾아올 수 있는, 영원한 난치병 암백신의 개발은 현대인들에겐 영원히 풀어야 할 숙제인 것이다.

세기말이 다가오면서 '역사의 종말'이니 '문화의 종말' 또는 '과학의 종말' 등 '종말'이라는 낱말로 끝나는 책들이 쏟아져 나오고 있다. 특히 '과학의 종말'이라는 의미는 20세기에 과학이 제시한 기본적인 문제들이 모두 해결된 것처럼 해석되기 쉽다. 그래서 오늘날 과학에서는 미결사항으로 정리하고 공백을 메우는 일만 남은 것처럼 비치고 있다. 그러나 과학자들에게는 아직도 과학이 해결하지 못한 수수께끼가 얼마든지 있다. 사람이 늙는 원인은 무엇일까? 3파운드 무게밖에 안되는 우리의 뇌가 의식현상을 어떻게 만들어내는 것일까? 우주의 종말은 어떻게 될 것일까? 우주에는 과연 종말이 없는 것일까? 불과 몇해 전만해도 답변할 수 없는 질문으로 여겼던 이런 문제들을 현재 과학자들은 온갖 상상력을 모두 동원하여 정력적으로 추구하고 있다. 월간 과학과기술은 현대과학이 아직도 풀지 못한 수수께끼들을 선별하여 새해의 새로운 읽을거리로 연재한다.

A person with neurological disorder is defined as a person with limitation of ambulation or basic life activity due to the cerebral palsy or traumatic brain damage, stroke. Recently, the DMFT of the children with neurological disorders is similar or lower than the DMFT of the children with no disability. But, this article is about the severe-early childhood caries in children with grade 1 neurological disorder. It is supposed that the primary motor impairment and secondary physical weakness, frequent hospitalization, sugar- rich food and drugs, lack of oral care, delayed dental visit made high caries susceptibility. In case of treatment of the children with severe neurological disorders, dentists should make a thorough caries preventive plan based on individualized caries risk assessment. Also parents and medical doctors should recognize the importance of oral care and do the early dental visit and home care.

The study aims to examine the rationality of the naming system with five properties of Korean pronunciation, which is used by most Korean name writer currently. A phonetic naming system is based on the premise that when a name is called, the sounds will have an audible effect on the speaker and the listener, and this phenomenon would ultimately have a good or bad influence on the owner of the name. The phonetic naming system is to name it by using five elements' coexistence and conflict of Korean pronunciation, and there are many progressing arguments that represent 'The Principles of Creation of Hunminjeongeum', 'The Historical Origin of Phonetic Naming System' and 'The Relevance of Modern Korean' etc. In the process of determining the validity of these arguments, distortion between the principles of creation of Hunminjeongeum and naming, a weak historical basis of the phonetic naming system, errors and problems in the usage of five elements of pronunciation, and fallacy of modern Korean phonology appear. For these reasons as above, the Korean phonetic naming system is concluded to be unreasonable, which claims not to be in line with the intention of creating Hunminjeongeum.

It is widely acknowledged that the human auditory system is organized tonotopically and people generally listen to sounds as a function of frequency distribution through the auditory system. However, it is still unclear how acoustic features of speech sounds are indicated to the human brain in terms of speech perception. Thus, the purpose of this study is to investigate whether two sounds with similar high-frequency characteristics in the acoustic analysis show similar results at the level of auditory brainstem. Thirty three young adults with normal hearing participated in the study. As stimuli, two Korean monosyllables (i.e., /ja/ and /cha/) and four frequencies of toneburst (i.e., 500, 1000, 2000, and 4000 Hz) were used to elicit the auditory brainstem response (ABR). Measures of monosyllable and toneburst were highly replicable and the wave V of waveform was detectable in all subjects. In the results of Pearson correlation analysis, the /ja/ syllable had a high correlation with 4000 Hz of toneburst which means that its acoustic characteristics (i.e., 3671~5384 Hz) showed the same results in the brainstem. However, the /cha/ syllable had a high correlation with 1000 and 2000 Hz of toneburst although it has acoustical distribution of 3362~5412 Hz. We concluded that there was disagreement between acoustic features and physiology outcomes at the auditory brainstem level. This finding suggests that an acoustical-perceptual mapping study is needed to scrutinize human speech perception.

Human and animals are born with an intuitive ability to determine approximate numerosity. This ability is termed approximate number sense (hereafter, number sense). Evolutionarily, number sense is thought to be an essential ability for hunting, gathering and survival. According to previous research, children with mathematical learning disability have impaired number sense. On the other hand, individuals with more accurate number sense have higher mathematical achievement. These results support the hypothesis that number sense provides a basis for the development of mathematical cognition. Recently, researchers have been examining whether number sense training can lead to enhancement in mathematical achievement and changes in brain activity in relation to mathematical problem solving. Numerosity which basically represents discontinuous quantity is expected to be closely related to continuous quantity such as representations of space and time. A theory of magnitude (ATOM) states that processing of number, space and time is based on a common magnitude system in the posterior parietal cortex, especially the intraparietal sulcus. The present paper introduces current literature and future directions for the study of the common magnitude system.

Through this study, we found out whether to measure objectively by using Transactional Analysis(TA) evaluating their own growth and benefit of health through the change of Ego-state, the personality structure and brain waves monitoring electric signals occurring in the brain of the human biological signals. According to the results of brain-wave test, M-type is brain-waves of healthy adults and a, ${\beta}$ were dominantly observed in the occipital while not sleeping. In particular, ${\beta}$ appears widely throughout the brain during nervous or concentrating metal activities and unlike N-type experimenters, ${\beta}$ was found to be dominant in M-type experimenters even in stable condition. N-type is brain waves of healthy adults and a, ${\beta}$ were dominantly observed in the occipital while not sleeping. In particular, unlike nervous or concentrating M-type, there was no noise such as tension and blink while resting. In addition, it turned out that subjects with high levels of A ego do not return quickly to the stable state and show a lot of Blinking and swallowing saliva, noise regardless of the pattern of Egogram. And brain waves of 11 people that the difference in data of OK-gram and Ego-state is the same in all items or less than -5 showed a low amplitude of $20{\mu}V$ in general. In conclusion, this study identified that the theory of personality pattern of Transactional Analysis Theory and brain-wave findings are consistent and also found out that brain waves are also associated according to each Ego-state of Egogram.

This study investigated the effects of Origanum majorana essential aroma therapy on electrical activity in the brain as evaluated by an electroencephalogram (EEG). The subjects were 29 healthy female young adults, and their sleep quality was assessed by using the Pittsburgh Sleep Quality Index. EEG electrodes were attached at the frontal, temporal, occipital, and parietal lobes according to the international 10-20 system. Subjects were exposed to organic Origanum majorana essential aroma (50 ${\mu}l$) for a period of 3 minutes each before, during, and after aromatherapy. Subjects with good sleep quality showed that Origanum majorana essential aroma increased the theta power at the frontal and temporal lobes of both cerebral hemispheres, the left parietal lobe, and the right occipital lobe. Furthermore, Origanum majorana essential aroma decreased the alpha power at the left occipital lobe and the beta power at the right temporal lobe. On the other hand, subjects with poor sleep quality showed an increase in the theta power at the temporal lobe of both cerebral hemispheres and a decrease in the alpha power at the left parietal lobe by Origanum majorana essential aroma therapy. It is concluded that Origanum majorana essential aroma therapy diminishes the state of wakefulness in the brain; alpha and beta powers were both decreased in the subjects with good sleep quality, but only alpha power was decreased in the subjects with poor sleep quality. Moreover, Origanum majorana essential aroma therapy has a sleep-inducing effect in both subjects with good sleep quality and poor sleep quality.
