The Purpose of this study was to evaluate the influence of fluoride uptake on microhardness and fluoride contents of tooth structure, Forty extracted human teeth were used, which were prepared proximal cavities. Experimental teeth were divided into five groups. Group 1: Prime & Bond NT and 2100 : Group 2 : Prime & Bond NT and F2000 : Group 3 : Scotchbond Multi-Purpose and 2100 : Group 4 : Scothcbond Multi-purpose and F2000 : Group 5 : Fuji Ⅱ LC. The cavities were filled with dentin adhesives and restorative materials. Teeth were coated 2 times with nail varnish. and immersed in a polypropylene tube. Tubes were stored in water bath at 37±0.5℃. After four weeks, the tooth was bisected longitudinally and the microhardness of the dentin and enamel were determined by indentation (at 30.100㎛ depth). The other halves were analyzed for fluoride by an EPMA-WDX device (at30, 100, 200㎛ depth). The results were as follows : 1. There was no correlation between the microhardness and amount of uptaken fluoride in the all groups. 2. There was no significant statistical difference in the amount of uptaken fluoride of the all groups in enamel without regard for groups and depth(p>0.05). 3. In the Group 2 and 5, EPMA-WDX result showed higher fluoride uptake of the. each depths in dentin(p<0.05). 4. At 30㎛ depth in dentin, EPMA-WDX result showed that group 2 had higher fluoride uptake than group 1 and 3 and group 5 had than the other groups. In conclusion, fluoride uptake increased by fluoride releasing materials. But, it was influenced by dentin bonding agents and surface conditions. Therefore, further study about relation between dentin bonding agent, surface coating, and fluoride uptake is necessary.

Objectives : Recently, some case reports have shown that risperidone is effective to refractory obsessive-compulsive disorder. Possible explanations for efficacy of risperidone in refractory obsessive-compulsive disorder maybe due to that it is both serolonin and dopamine receptor antagonist. On the basis of serotonin-dopamine interaction hypothesis, a biological etiology of obsessive-compulsive disorder, the effect of risperidone was evaluated to the suppressed spontaneous alternation behaviour of animal model of obsessive-compulsive disorder in rats. Methods : The apparatus for spontaneous alternation behaviour was a black plexiglas T-maze with distinctive black and white goal boxes. Black gullotine doors separated the start box and the goal boxes from the main body of the T-maze Small cups were placed in the corners of both goal boxes(all arms measured 50×10cm) 24 hours prior to experiment, rats(Spraque-Dawley) were food-deprived. The food-deprived rats were put into T-maze, in which both goal boxes were baited with small amounts of chocolate milk. Each rat was given 2 set of 7 trials during which it was placed in the start box and allowed to choose the one of the goal boxes for checked. After baseline of the number of choices of spontaneous alternation behaviour was stabilized, the pontaneous alternation disrupted by nonselective 5-HT agonist, 5-MeODMT (1.25mg/kg/IP). The experimental animals were stratified into 5 groups, fluoxetine(10mg/kg/IP), risperidone(0.1mg/Kg/IP), haloperidol(0.1㎎/Kg/IP), fluoxetine(10mg/Kg) with haloperidol(0.1 mg/Kg), and saline(0.5cc/IP) control group. Each drugs were injected for 21 days as a chronic treatment. The protective effects were evaluated on the nest day of discontinuation of the each drugs among 5 groups. Results : 1) After 21 days of the drug treatment, the risperidone group and the fluoxetine group showed significant difference from the haloperidol group and the saline control group on the protection of the 5-MeODMT induced suppression of spontaneous alternation behaviour. 2) The fluoxetine group and fluoxetine with haloperidol group showed significant difference between before and after treatment in the protection of 5-MeODMT induced suppression of spontaneous alternation behaviour. The risperidone group also showed significant difference between before and after treatment in the protection of 5-MeODMT induced suppression of spontaneous alternation behaviour, but the protective effect of risperidone was superior to fluoxetine. Conclusion : These findings suggest that both risperidone and fluoxetine have a favorable effect in the protection of 5-MeODMT induced suppression of spontaneous alternation behaviour. We think that risperidone can be possible alternatives to SSRIs in the treatment of refractory obsessive-compulsive disorder in clinical situation.

李震熙,金裕逸 성균관대학교 생명과학자원연구소 1997 生命資源科學硏究 Vol.4 No.1

Natural recreational forests and nature parks are major facilities for city dwellers to do leisure activities. The acts of natural recreational forest and nature park are commonly enacted for the purpose of enhancing public health and emotional life. The Natural recreational forest act is enacted to increase income of forest owner as opposed to the nature park act which is enacted to protect scenic beauty. Several points in the natural recreational forest act are focused as follows; 1. The expenses for the installation of new facilities required by new act may reduce income of the forest owners. 2. As tourists trend to be family types and lodging tourists and commercial facilities can not accommodate the tourists. 3. There may be lack of a public service against crime, fire, disaster, etc. To improve the natural recreational forest act, it is suggested that lodging and commercial facilities need to be provided more, public services need to be enforced to reduce environmental damages.

The status of facilities, management of the experiment, practices, and Science education teaching method in middle school have been investigated. The present status and reasonable management of middle school science education have been grasped from the questionaires. The results are as follows : The reasonable management for expeiments and practices of science education were scanty in the middle school around the urban and rural schools owing to the shortage of facilities and equipments, crowded class, excessive classes, work for teachers, excessive contents of present textbook and insufficience of administrative support etc. The current teaching method of middle school science has emphasized knowledge. This fact does not satisfy the objective of learning due to lack of teaching method. Desirable directions for the improvement of present status of middle school science education were proposed in this paper.

현대건축에서 맥락 드러내기의 새로운 방향성 모색 : 들뢰즈ㆍ가타리의 “기관 없는 신체” 개념을 중심으로 Focused on Deleuze & Guattari's idea of "Corps sans Organes"

이진아,권태일,이동언 대한건축학회 2004 대한건축학회논문집 Vol.20 No.8

Context in architecture cannot be intentionally conceptualized and reduced to materialness but rather ‘the virtual of context' that has been flowing and changing continuously. Because it is not so much the representation by habitual memory as the presentation that truly means the creation. Therefore, this paper investigate into a new direction of contemporary architecture in terms of actualizing true meaning of context through Deleuze and Guattari's idea of ‘Corps sans Organes' that has the character opened to all directions and making creativity; ‘the plan of consistence'.

목적 : 인유두종 바이러스는 자궁경부암의 의의있는 원인 인자이다. 이 연구의 목적은 HPVDNAChip??검사를 이용하여 정상, 전암병변, 침윤성 경부암의 인유두종 바이러스의 분포를 알아보고 그 결과를 Hybrid CaptureⅡ^(^(TM)) 검사와 비교하였다. 연구 방법 : 149명의 대상환자 중 57명은 병변이 없었고, 59명은 전암 병변이었으며, 33명은 침윤성 경부암이었다. HPVDNAChip??검사와 이 검사처럼 아형 66, 69를 제외한 고위험군(HPV-16/18/31/33/35/45/51/52/56/58/59/68) 인유두종 바이러스를 검사할 수 있는 Hybrid CaptureⅡ^(^(TM))검사를 이용하여 연구하였다. 결과 : 두 검사 모두 인유두종 바이러스를 검사하는 데 유용하였고, 결과가 의의있게 일치하였다(kappa value 0.721, p<0.01). Hybrid CaptureⅡ^(^(TM))검사에서 양성이나 HPVDNAChip??검사에서 음성인 경우는 18명(12.1%)으로 평균 Hybrid CaptureⅡ^(^(TM))값이 120.7±233.0 (mean±SD)이였고, 두 검사 모두 양성인 경우의 Hybrid CaptureⅡ^(^(TM))값은 448.1±732.8 (mean±SD)이였다. Hybrid CaptureⅡ^(^(TM))검사의 민감도는 94.6%이고, 특이도는 78.9%였고 HPVDNAChip??검사의 민감도는 83.7%이고, 특이도는 89.5%였다. HPVDNAChip??검사는 모두 15가지의 고위험군의 인유두종 바이러스 아형을 알아낼 수 있으며 아형 16이 전암병변(28.8%, 15/59)과 침윤성 경부암(48.5%, 19/33)에서 가장 흔한 아형이었으며 그 다음으로 흔한 아형은 58이었다. 결론 : HPVDNAChip??검사는 Hybrid CaptureⅡ^(^(TM))검사처럼 인유두종 바이러스 검사에 매우 민감하고 유용한 검사이다. HPVDNAChip??검사는 Hybrid CaptureⅡ^(^(TM))검사와 비교할 때, 인유두종 바이러스의 아형과 중복감염에 대한 정보를 준다. 앞으로 HPVDNAChip??검사의 자궁경부암의 선별검사로서의 가치에 대한 연구가 더 필요하다. Objective : Human Papillomavirus (HPV) is well known as one of the major risk HPVDNAChip?? factors for cervical cancer. The purpose of this study is to know HPV genotype distribution in women with normal cervix, precancerous lesion, and invasive cervical cancer by HPVDNAChip?? test. In addition, the result of HPVDNAChip?? test was compared with Hybrid CaptureⅡ^(TM) system for HPV detection. Methods : One hundred forty nine patients were included in this study. 57 women had normal cervix, 59 women had precancerous lesion, and 33 women had invasive cervical cancer. We tested them with two method for detection of Human Papillomavirus (HPV) by HPVDNAChip?? test and Hybrid CaptureⅡ^(TM) system. Hybrid CaptureⅡ^(TM) test can detect same high-risk HPVs (16/18/31/33/35/39/45/51/52/56/58/59/68) with HPVDNAChip?? test which can detect additional 66 & 69 high risk types of HPV. Results : Both methods for the detection of HPV were useful tests. The correlation between the results of two methods was very significant (kappa value 0.721 [p<0.01]). Positive Hybrid CaptureⅡ^(TM) test and negative HPVDNAChip?? test group were 18 women (12.1%) and average Hybrid CaptureⅡ^(TM) titer value of this group was 120.7±233.0 (mean±SD), positive Hybrid CaptureⅡ^(TM) test and positive HPVDNAChip?? test group were 84 women (54.4%) and average titer was 448.1±732.8. The Hybrid CaptureⅡ^(TM) test showed a sensitivity of 94.6% and a specificity of 78.9% and the HPVDNAChip?? test showed a sensitivity of 83.7% and a specificity of 89.5%. HPVDNAChip?? test detected total 14 genotype of HPV. HPV-16 was 28.8% (15/59) in precancerous lesion and 48.5% (19/33) in invasive cancer, most common in both groups. Next common type HPV-58 was 25.4% (12/59) in precancerous lesion and 9.1% (3/33) in invasive cancer. Conclusion : HPVDNAChip?? test is very sensitive and effective method for detection of Human Papillomavirus (HPV) infection as Hybrid CaptureⅡTMtest. In comparison with Hybrid CaptureⅡ^(TM) test, HPV genotype and multiple HPV infection information can be given by HPVDNAChip?? test. Further study will be needed to know the value of screening of cervical cancer by HPVDNAChip?? test in future.
