Aim : The purpose of this study was to investigate the hypothesis that treatment with self-checking behavior management program was valuable in the management of temporomandibular disorders compared with a existing method treatment group. Methods : All participants who are diagnosed with temporomandibular disorders were treated with medication and physical therapy. They came into the clinic at intervals of two weeks, three times. The signs and symptoms were assessed investigating Pain NRS(Numerical Rating Scale), MCO(Maximum comfortable opening), Noise NRS, LOM(Limitation of Mouth opening) NRS at every visit. Experimental group received instructions repeatedly by using self evaluation questionnaire. Control group was educated once at the beginning of treatment. The difference Pain NRS, MCO, Noise NRS, LOM NRS between first and second visits, first and third visits were estimated.. Result :Experimental group showed greater improvement on MCO difference after stopping medication(p=0.001). This improvements were prominent in the male(p=0.001) and the first or second decade of the patients(p=0.004). Conclusion : The present study showed that there was better result when educating repeatedly with using self evaluation questionnaire than educating once at the beginning of the treatment.

[ $\lceil$ ]한국산 명나방과(Pyralidae)에 관하여는 이미 필자(1976)에 의하여 언급된바와 같이 1889년 영국인 곤충학자 J.H. Leech가 처음으로 9종의 신종을 발표한데 이어 현재까지 300여종이 기록되어 왔다. 그러나 이들의 기록이 여러종류의 발표문에 산재해 있는 상태로 체계적인 정리가 이루어진바 없으며 학명뿐아니라 우리말 이름조차 갖가지로 쓰여지고 있어 곤충명 사용에 혼란이 야기되고 있는 실정이다. 이에 필자는 현재까지 발표되었던 종들을 조사하여 최근의 분류체계에 따라 학명 및 그들의 동의어(Synonym)를 정리함과 아울러 우리말 이름도 먼저 명명된 이름이나 또는 현재 많이 사용되고 있는 이름을 택하여 통일화하고 ( )안에 그 이명을 표시하였다. Evergestiinae(새들명나방아과, 신칭)은 현재까지는 주로 Pyraustinae(들명나방아과)에 포함되는 족(Tribe)으로 취급되어 왔으나 최근의 분류체계에 따라 독립된 아과로 취급하였다. 이들에 대해서는 Leech에 이어 일본인 Shibuya(1927년에 의하여 13종, 박세욱등 (1958, 1969)에 의하여 27종이 새로 기록되는등 1968년에 출판된 한국 동물명집 곤충편에는 94종이 수록되었다. 최근 필자(1976)에 의하여 우리나라 미기록종으로 발표된 24종과 기타 국내외의 문헌을 통한 기록의 근거를 기초로 작성된 이 목록에는 Evergestiinae에 1속 3종, Pyraustinae에 53속 123종이 포함되었으며 학명이 불분명하거나 채집의 근거가 불확실한 4종은 후미에 별도로 기재하였다. 분포란의 괄호안에 명시된 채집지는 필자에 의하여 채집 확인된 종들로서 그들의 표본은 농업기술연구소 곤충연구담당관실 표본실에 소장되어 있다. 다른 아과에 관하여는 정리가 완료되는대로 추후 발표할 예정이다.nemella hengsungica, Aphelenchoides besseyi 등으로 2아목 7과 11종이었다.는 내연가공한 옷생산에 사용되지 않는 것이 타당하겠다. 주아의 즙액에 의해서도 C. amaranticolor에 기계적 전염이 되었다. 7. C. amaranticolor 상에 계통분리된 마늘 모자이크 바이러스의 내열성은 $65^{\circ}-70^{\circ}C$, 희석한계는 $10^{-}2-10^{-3}$, 그리고 보존한계는 2 일이었다. 8. 마늘 모자이크 바이러스의 순화는 2회의 분획원심과 Sephadex gel filtration에 의해서 가능했다. 9. 전자현미경하에서 관찰한 마늘 모자이크 바이러스는 길이 1200-1225mu 폭 10-12mu의 사상이었다. 10. 혈청학적 미량침강 반응법에 의해 마늘잎에서뿐만 아니라 인편과 주아에서도 마늘 모자이크 바이러스의 검정이 가능했다. 11. 우리나라 5개 지방에서 수집한 마늘 종구 150개와 주아 30개에 대해 혈청학적방법으로 마늘 모자이크 바이러스의 감염률을 조사한 결과 $100\%$의 감염률을 보였다. 12. 마늘 모자이크 바이러스와 크기가 근사한 Potato Virus X. Potato virus Y, Potato virus S, Potato virus M 등과의 혈청학적 유연관계를 조사한 바, 마늘 모자이크 바이러스는 이들과 구별되는 다른 바이러스라고 생각된다. 13. 마늘의 모자이크 감염주에서 단일계통으로 분리하여 본 실험에 사용한 바이러스는 마늘의 바이러스 무감염주를 얻을 수가 없기 때문에 직접 마늘잎에 접종해서 모자이크톤의 병원이라는 것을 확인할 수 없었지만, 검정식물상의 반응, 혈청학적반응, 전자현미경적 관찰등의 간접적인 조사 결과로 미루어 미인록의 마늘모자이크 바이러스라고 생각된다

The purpose of this study was to investigate the effects of combined exercise program on short physical performance battery, bone mineral density and parathyroid hormone levels in elderly women. This study subjects were 22 elderly female volunteers, aged 65-75 years and they divided into the combined exercise group(n=11) and the "no exercise" control group(n=11). The combined exercise included the line dance program performed twice per week for 60 minutes and the resistance exercise program performed once per week during 12 weeks. Exercise intensity was progressively increased from RPE "fairly light" to "slightly hard" (from 11 to 14). The findings of this study were as follows; Short physical performance battery(Balance test, gait speed, and rising from a chair five times) and bone mineral density (lumbar spine L2~L4 bone densities, and the T-score) were significantly increased after 12 weeks in the exercise group compared to the baseline. The PTH level was significantly decreased in the exercise group compared to the baseline. In conclusion, regular and continuous physical activity was effective for improving short physical performance and had a positive effect on bone mineral density and parathyroid hormone. With aging, women have decreased muscle strength and bone density and therefore, it is strongly recommended that women need to carry out continuous physical activity to prevent disease and ensure a healthy retirement.

This study aims to examine the level of fear and the influential factors affecting their dental fear and to utilize the result as the basic materials in the dental management. The subjects were the students from a middle school located in Cheongju-City. The school was selected by convenient sampling and self-answered questionnaire was filled in by the students for a week from December 19th 2011. The survey result showed that 77 male students and 169 female students(total 246 students) answered 'yes' to the question 'Have you ever felt fear when you visited a dentist?' among 475 students who had visited a dentist in the past. The distribution of responses in each category of fear was examined by frequency analysis. The study results showed significant difference in the item of 'causing irritation during the dental treatments' between male students and female students (p<0.05). Converting the level of fear into scores after marking the answers, the score of male students was 52.0 points and the score of female students was 58.53 showing the score of female students was significantly higher in statistics. Moreover, the fear score of female students for the category 'causing irritation during the dental treatments' was also significantly higher in statistics(p<0.05). Therefore, these results should be reflected to the dental care environments in order for the adolescent to reduce the dental anxiety and fear.

This convergence study analyzed the effectiveness of contrast agent reduction by normal saline solution dilution in the computed tomography of arteries of lower limb. 48 patients of 125 cc contrast agent and 30 patients of the same amount divided at a ratio of 7:3 for the contrast agent and normal saline solution were studied. The average attenuation coefficient(HU) and signal to noise ratio(SNR) of abdominal aorta, femoral artery, popliteal artery and posterior tibial artery at each image were evaluated quantitatively and the four criteria in the five point scale was conducted qualitatively by two radiologists and four radiological technologists. In the quantitative evaluation, both HU and SNR had high average score before dilation but there were no statistical significance by independent t-test(p>0.05). In the qualitative evaluation, there were a little differences in the average scores between 4.86~4.77 of original contrast agent and 4.83~4.67 of dilated contrast agent but there were no statistical significance(p>0.05). In the computed tomography of arteries of lower limb, the dilated contrast agent doesn't influence image quality and reduces overall contrast agent and lowers iodine content per unit of molecular therefore will contribute to decrease side effect of contrast agent.
