본 연구의 목적은 시중 어린이 음료의 산성도를 조사하고, 수 종 어린이 음료에 의한 유치 법랑질 침식정도를 실험적으로 평가하는 것이었다. 서울 시내 및 경기도 지역에서 판매순위가 비교적 높은 수 종의 어린이 음료를 표집하여 pH를 측정하고, 그 중에서도 pH 3.5 이하의 어린이 음료 7개를 선별하였다. 탈락기의 건전한 법랑질 표면을 가진 유치를, 어린이 음료에 1 분, 5 분, 10 분, 15 분, 30 분 동안 노출시켜 인공적으로 법랑질 침식을 유도하였을 때 나타나는 양상을 표면미세경도측정법으로 분석하여 다음과 같은 결론을 얻었다. 1. 본 연구에서 조사한 시중 어린이 음료의 대부분은 치아 침식을 유발할 수 있는 산성도인 pH 5.5 이하의 산성도를 갖고 있었다. 2. 어린이 음료에 대한 노출 후의 법랑질 표면미세경도는 대조군에 비해 모든 시료에서 낮아졌다(p<0.05). 노출 후 1 분이 경과되었을 때부터 표면미세경도의 유의한 감소 양상을 보였으며, 30 분이 경과되었을 때까지 표면미세경도의 감소가 계속 관찰되었다(p<0.05). 3. 음료의 산성도가 높을수록, 시편을 30 분간 노출시켰을 때의 표면미세경도가 유의하게 감소했다(p<0.05). 그러나 음료의 산성도와 표면미세경도의 감소정도 사이에 유의한 비례관계는 찾을 수 없었다(p>0.05). The purpose of this study is to examine the acidity of beverages that are sold for children in the market and to estimate by experiment the degree of the enamel erosion of deciduous teeth that is attributed to the beverages. The pH value of children beverages among top sale list in Seoul and Gyeonggi province were measured. And 7 beverages with the pH value of 3.5 or lower were selected. The enamel erosion of deciduous teeth by the children beverages for 1, 5, 10, and 30 minutes respectively was examined. The results were as follows: 1. The acidity of most of the children beverges examined in this study was the pH level of 5.5 or lower that can cause the tooth erosion. 2. The microhardness value of the enamel of deciduous teeth was lower as exposing it to children beverages. The reduction of surface microhardness value was significant from 1 minute after the exposure, and the reduction was continuously observed until 30 minutes has passed. 3. The higher the acidity of beverages, the larger the reduction in microhardness value caused after the exposure of 30 minutes to the beverages. There was no significant relation between the acidity of beverages and the reduction rate of surface microhardness value. The other factors such as calcium, phosphorus, and fluorine or buffering of the beverages may affect the enamel erosion.

This study was planned to suggest countermeasure of nutrition education by investigating adolescents, dietary behavior, food weight, and acknowledgement of food calories. 210 middle school boys were selected and asked to fill out the questionnaire. The subjects were divided by nutrition education experience; 1st grade who received nutrition session and 3rd grade who divided subjects. In terms of acknowledgement of food calories subjects nutrition education experience had more recognition for calories than the other group(p<0.01). When one bowl of rice, a potato, a bowel of kimchi and a carrot were asked. However recognition for meats, fishes and eggs were not different between two groups. Among milk and dairy foods the educated group showed high recognition both calories and weight of a piece of cheese than the other(p<0.05). The educated group showed better recognition for calories and weight of tea-spoon of butter, a tea spoon of oil and a tea-spoon of mayonaise, compared to the other group(p<0.01, p<0.05, p<0.05). Also the educated group showed better recognition for calories and weight of a packet of shrimp snack than the other group. The results of this study suggest that nutrition education improved the recognition of calories and weights of foods in study subjects. Also, the number of foods recognized for their calories and weights was higher among subjects who received nutrition education. These results will influence the choice the food by adolescents. Also the nutrition education are thought to be more effective by using photographs or food models, not just by lectures on theories.

Objectives : Acupuncture is expected to have somewhat like the efficacy parallel increasing activity of immune system in Western modern medicine. There, already, are many animal researches on activating effect of acupuncture for the immune system in peripheral organs. So, we carried out this experiment to see whether acupuncture has controlling effect on interleukin-6(IL-6) activity in rat's brain. Methods and Results : We had topical application of IL-6(1U-1pg, 10㎕) on brain of rat. It reduced afferent sensory transmission to the primary somatosensory(SI) cortex from periphery. Whereas, electrical stimulation(ES, 2Hz, 1.5V, 15min) of ST36(足三里) with application of IL-6 prominently activated afferent sensory transmission. ES of non-acupoint(proximal tail) with IL-6 showed suppression of afferent transmission. ES of ST36 without IL-6 application also exerted facilitation of afferent transmission to the SI cortex. Conclusions : Electoacupuncture(EA) on ST36 has noticeable influences on modulating activation of IL-6 in central nervous system, which do major role in immune system.

포스트가 축조된 치아를 재근관 치료하는 경우 성공적인 비외과적 재근관치료를 시행하기 위해서는 포스트 제거가 선행되어야 한다. 기존의 포스트를 제거하는 방법으로는 초음파기구, Ruddle post removal system, Eaggler post remover, Masserann kit을 이용하는 방법 등 여러 가지가 소개 되고 있으나 기존의 방법들은 각 기구에 맞게 코어를 삭제해야 하는 시간과 많은 노력이 요구되며 포스트 제거시 치아나 포스트의 파절이 유발되기도 한다 그러나 최근에는 기존의 방법과는 다른 ATD automatic bridge remover를 이용해 포스트를 제거하는 새로운 방법이 소개되고 있으며 코어에 구멍을 형성하는 시간만 소요되어 비교적 빨리 제거 할 수 있다는 장점을 가지고 있다. 따라서 본 증례에서는 ATD automatic bridge remover를 이용해 주조포스트를 제거하고 성공적으로 재근관치료를 시행한 증례에 대해서 보고하고자 한다. It is common for clinicians to encounter endodontically tl·treated teeth that contain posts within their roots. If endodontic treatment is failed, these posts must be removed to facilitate successful nonsurgical retreatment. There have been many techniques such as ultrasonic instrument, Ruddle post removal system, Eggler post remover and Masserann kit developed to facilitate removal of posts from the root canal space. But these methods may be disadvantageous because long length of time required for post removal and fracture of post or teeth. In now days new post removal technique using ATD automatic bridge remover was introduced. Advantages of this method are simple and short time consuming compare to others. This article served as a successful case report of post removal using ATD automatic bridge remover.

본 연구는 fMRI를 사용하여 정서유발단어에 의한 주의이동과 관련한 뇌신경망을 규명하기 위하여 12명의 오른손잡이 여대생을 대상으로 수행하였다. fMRI 실험을 위한 뇌활성화 과제는 예비실험을 통하여 선정된 행복, 슬픔, 위협에 해당하는 각각 36개씩의 단어와 각 단어의 짝을 이루기 위한 중성단어를 이용하여 변형된 Posner 패러다임을 블록디자인으로 고안하였다. fMRI 영상은 1.5T Simens Vision scanner를 사용하여 실시하였으며, single-shot EPI 기법으로(TR/TE:3840/40ms, flip angle: 90, FOV: 220, 64x64 matrix, Slice thickness: 6mm) 이미지를 얻었고 피험자의 반응시간을 기록하였다. 자료분석은 SPM-99 소프트웨어를 사용하였다. 정서유발단어는 중성단어에 비하여 반응시간이 의미있게 빨라 효과적인 주의이동이 일어났음을 알 수 있었다. 정서유발단어와 중성단어에 의한 뇌활성화 상태를 감산분석한 결과, 좌측 상두정엽, 양측 후두엽 및 소뇌에서 뇌활성화를 보였고, 이들 영역은 정서유발단어에 의한 주의이동시 특징적으로 활성이 일어나는 뇌영역임을 보여주었다. 또한 여러 가지 정서가를 가진 단어에 의해 유발되는 주의의 정도가 특징적인 신경망의 활성과 관련되어 있음을 알 수 있었다. The purpose of this study is to delineate the neural network related to the shift of attention and its modulation by emotion-provoking words using functional MRI (fMRI). Twelve right-handed normal female volunteers participated in fMRI study. Their mean age was 24 years and the mean modified Edinburgh score was +90. Emotion-provoking words representing happy, sad, threatened, and neutral emotional valences respectively were chosen by the assessment of 60 normal volunteers using semantic differentiation and Mannequin scales. The activation tasks were designed using modified Posner's paradigm to have 4 blocks of each emotional and control periods, Imaging was conducted on a 1.5T Siemens Vision scanner. Single-shot echoplanar images (TR/TE = 3840/40 ms, flip angle = 90, FOV = 220, matrix = 62 ? 64, slice thickness = 6㎜) were acquired in 20 contiguous slices parallel to the AC_PC line as well as conventional T1-weighted images. Response times were obtained during the scanning, Imaging data were realigned, coregistered, normalized, smoothed, and statistically analyzed in group using SPM-99 software. The results showed that emotional valence of word stimuli produced the effect of attentional engagement. The left superior parietal, inferior frontal, bilateral occipital lobes and cerebellum were main area of modulation of attentional network by emotional words stimuli. The different extent of brain activation induced by different emotion-provoking words were determined.

본 연구의 목적은 첫째, 학생들이 과학적 관찰 및 규칙 발견 활동을 수행할 때 나타나는 과학적 감성 단어의 유형과 빈도, 강도를 분석하고, 둘째, 과학 지식 생성력과 과학적 감성지수(ISE)와의 상관관계를 밝히는 것이다. 이를 위해 연구에서는 먼저 선행 연구를 고찰하여 과학적 감성을 정의하고, 효과적인 지식 생성 활동을 위해 겨울눈과 화석 관찰, 씨앗과 암석 분류의 4개의 과제를 개발 하였다. 연구대상은 교원양성대학교 4학년 학생 161명으로 하였다. 피험자들은 각 과제를 수행하면서 인지적 사고과정과 느낀 과학적 감성을 기록하고 형용사 이모티콘 척도 용지에 자신의 감성 강도를 나타내었다. 연구 결과, 관찰 활동에서는 '흥미-수용-사랑-거부'의 순으로 감성유형이 나타났고, 규칙성 발견 활동에서는 '흥미-거부-수용-기대'의 순으로 감성유형이 나타났다. 각각의 감성 단어 빈도는 감성 강도와 통계적으로 상관관계가 있었다. 과학적 감성 빈도(FSE)와 과학적 감성 강도(SSE)를 곱한 과학적 감성지수(ISE)는 과학적 감성능력을 나타내는 하나의 지표로서 과학 지식 생성력과 높은 정적인 상관관계를 가진다. 개별적인 과학적 감성 지수에서는 '수용-사랑-슬픔-흥미'순으로 과학 지식 생성력과 정적인 상관관계를 나타낸다. The purposes of this study were to analyze types of scientific emotion word and to investigate the relationship between the ISE(Index of Scientific Emotion) and the ability of science-knowledge generation in subjects' scientific observation and rule-discovery. The subjects were asked to perform four scientific tasks. The tasks were developed that are suitable for scientific observation and rule-discovery. In performing tasks, the subjects were asked to describe their generated science-knowledge and scientific emotion through self-report questionnaire, performing each task. The strength of their scientific emotion was also measured using adjective emoticon check lists. In subjects' scientific observing, they showed 33.3% of interest emotion which was the biggest, 15.0% of acceptance emotion, and 11.3% of love emotion, respectively. In scientific rule-discovering, types of emotion were shown as 23.8% of interest, 21.5% of disgust, and 10.8% of acceptance, respectively. In addition, ability of science-knowledge generation was significantly correlated to ISE.

The acute and subacute toxicity of New Woohwangchungsimwon(NWCH) which was used l-muscone as substitutive material of musk were investigated in S.D. rats. In intraperitoneal acute toxicity test, rats(Sprague-Dawley, SPF) were injected intraperitoneally with dosages of 0, 540, 750, 1,070, 1,500 and 3,000 ㎎/㎏. Body weights were significantly decreased at 540 ㎎/㎏ dose group in both sexes and abnormal autopsy findings were founded in both sexes at all treated groups. Intraperitoneal LD_50 of NWCH was 812.3 ㎎/㎏ in male and 872.3 ㎎/㎏ in female rats. In the subacute toxicity study, NWCH was administrated orally to both sexes of rats for 4 weeks as several doses(0, 320, 800 and 2,000 ㎎/㎏). There were neither dead animals nor significant changes of body weights during the experimental period. In addition, no differences were found between control and treated groups in clinical signs, urinalysis, hematology, serum biochemical analysis, and other findings. Above data strongly suggest that no observed adverse effect level of NWCH might be over 2,000 ㎎/㎏/day in this study.
