It has been generally known that smoking is one of the worst factor increasing disease and mortality in human health since in 1950's and nowadays. But regardless of various proofs about social or economical problems due to smoking, current smoking rate has not been decreased in our country. Until now, most of tobacco use and its addiction researches have been focused on the adolescent or adult women smokers not on the university students. Therefore, the purpose of this study was to investigate smoking cessation of university smokers and analyze the health belief-perceived sensitivity, severity, benefits and barriers- difference, then to provide basic data for effective smoking cessation strategy for university smokers. The subjects were comprised of 181 university smokers from 15 universities in Seoul. The data were collected by structured questionaires. The questionaires were designed to measure general characteristics, smoking cessation and health belief, based on Ahn(2003)'s result on the Study of Smoking attitude, Behavior and Smoking Cessation of Adult Male and Lee(1987)'s result on Relationships Between the Health Belief Model and Smoking Habits. The data were collected from May 5 to 16. The collected data were analyzed by SPSS program. The actual number, percentiles, means, standard deviation, t-test and ANOVA were done. The result of this study were as follows; 1. The general characteristics of the subjects of this study The range of age was from 18 to 34 and the averaging age was 23. The subjects of this study were 141 males and 40 females. The religions were Christianity 25.4%(46), Buddhism 12.7%(23), Catholic 23.2%(42), no religion 37.0%(67).

The smoking cessation of the subjects 80% of current smokers showed quitting smoking decision and 20% have not tried. The frequency of quitting smoking decision were from 1 to above 8 and mean was 3.06. As for smoking cessation plan, 54.7%(99) current smokers answered yes, 3.9%(7) said no, 35.4%(64) had no idea and 6.1 %(11) didn't answer. As for the reason of never quitting smoking decision, 71.42%(25 among total 35) have no need to quit smoking and the others said difficulty of smoking cessation. As for the main reason of smoking cessation decision, 54.7%(99) answered for the health, 7.2%(13) family advice, 15.5%(28) girl/boy friend's advice, 1.7%(3) to save money. As for the reason to fail smoking cessation, 56.7%(68) were will-lack, 17.5%(21) stress, 15%(18) smoking mood, 10%(12) withdrawl symptom. As for the smoking cessation method, 85.0%(125) were oneself-will, 2.7%(4) way acquired by mass-media, 2%(3) doctor's prescription, 2%(3) religion's help, 0.7%(1) smoking cessation school. As for the difficulty in smoking cessation, 42.2%(62) were drinking meeting, 23.1 %(34) no alternative of stress release, 12.2%(18) withdrawl symptom, 11.6%(17) having nothing to do, 7.5%(11) friend's encouragement. As for the most difficult cigarette to quit, 67.8%(99) were all-day smoking except the first smoking in the morning, 32.2%(47) the first smoking in the morning. 3. Health belief as for general characteristics Gender - The total point in benefits showed higher in male(28.5177) than female(26.6750). There was significant difference(t=.778, p<.05). The total point in health belief showed higher in male (105.8298) than female(l00.5000). So there was significant difference(t=.345, p<.05). Age - There was significant difference in benefits between age(10's-25.83, 20's-28.39, 30's-32.00)(F=3.73, p<.05). Smoking starting age - There was significant difference in total point of sensitivity and health belief(sensitivity F=4.00, p<.Ol, health belief F=2.843, p<.05). As for sensitivity, subjects who started smoking in the army showed the highest(33.36) and ones in high school showed the lowest(26.96). The total point in health belief showed the highest in elementary school(l19.00) and the lowest in high school(100.98). 4. Health belief as for smoking cessation There was significant difference in health belief as for smoking cessation(t=0.189, p=0.OO2). Sensitivity point showed higher in smoking quitting trial smokers(29.2) than non-trial smoker (26.9). Severity point showed higher in trial smokers (30.7) than non-trial smokers(28.9). Benefit point showed higher in trial smokers(28.6) than non-trial smokers(26.2). There was no significant difference in barriers point.

본 실험은 한국, 중국 및 일본 재래종 콩 유전자 자원의 주요형질 변이를 조사하고 이들 자원간의 지리적 유연관계를 비교하고자 수행하였으며, 그 결과를 요약하면 다음과 같다. 1. 경장은 한국(66㎝)이나 일본자원(54.9㎝)보다 중국자원(71㎝)에서 더 컸으며, 또한 변이도 중국자원에서 가장 큰 것으로 나타났다. 2. 개화일수 및 생육일수는 한국자원(65.5일, 151.4일)이 가장 길었으며 중국(57일, 120일)과 일본자원(59.9일, 122.4일)은 같은 경향을 나타냈다. 또한 한국과 중국자원은 지역에 따른 차이를 나타냈으나 일본자원에서는 확인할 수 없었다. 3. 백립중은 한국(18.8g), 일본(17.2g) 및 중국(14.7g) 순으로 무거웠다. 특히 한국자원은 9~11g과 23~25g에서 정점을 나타냈고, 변이폭도 가장 컸다. 반면 일본과 중국자원은 13~17g사이에서 정점을 나타냈다. 4. 협수는 중국(46.9개)이나 일본자원(36.5개)보다 한국자원(75.5개)에서 가장 많았으며, 변이폭도 한국자원에서 가장 컸다. 내도복성은 일본자원에서 가장 강하였다. 5. 정준판별분석결과 can 1을 경계로 하여 오른쪽 상하에 한국재래종이 주로 분포하였고 왼쪽에는 중국과 일본 재래종이 주로 분포하여 각 나라별로 고유한 영역을 가지고 분리되었다. 전체적 경향이 중국과 일본자원이 한국자원보다 가까운 경향을 나타냈다. This experiment was carried out to compare the characters of 944 Korean soybean landraces, 716 Chinese, and 170 Japanese soybean landraces introduced from USDA soybean germplasm collection. Cannonical discriminant and cluster analyses were conducted by their origins. The population from China was taller in plant height than those from Korea and Japan, also its variation was largest in Chinese population. The population from Korea was langer than those from China and Japan in terms of days to flowering and maturity. Also, Korean and Chinese accessions appeared the difference of those traits according to latitude. One hundred seeds weight was in the order of Korean(18.8g), Japanese(17.2g) and Chinese populations(14.7g), especially Korean population was distinguished into two groups; the group including accessions between 10 and 15g, and the other group including accessions between 20 and 25g. However, others showed the peak in range of 13~17g. The number of pod per plant was more in Korean accession(75.5) with the largest variation than Chinese(46.9) and Japanese accession(36.5). The distribution of Korean, Chinese and Japanese accessions reflected the origin of accessions analyzed by cannonical discriminant analysis. The relationship between their geographical origins showed the population of China and Japan are losely related.

To study the effect of platelet-derived growth factor(PDGF) on the replication and collagen synthesis of rat calvarial cells, five bone cell populations(I-V) were prepared from fetal rat calvaria by sequential enzyme digestion. After primary culture for 6-7 days, each bone cell population was collected and then population Ⅰ and Ⅱ, Ⅳ and Ⅴ were pooled together. And the cells were resuspended at 6-8×10^4 cells/㎝^2 and cultured for 2-3 days. The medium was changed to serum-free medium prior to addition of growth factor. The effect of PDGF on the cell proliferation was measured by the incorporation of [^3H]thymidine into DNA. Protein synthesis was determined by measurement of [^3H]proline incorporation into collagenase-digestible protein(CDP) and noncollagenous protein(NCP) according to the method of Peterkofsky and Die-gelmann(1971). The observed results were as follows. 1. PDGF at 10 ng/㎖ significantly increased the [^3H]thymidine incorporation into DNA in all bone cell populations. 2. PDGF at 30 ng/㎖ significantly increased the synthesis of NCP in population Ⅰ, Ⅱ and Ⅳ, Ⅴ. 3. PDGF had no effect on the synthesis of CDP but percent collagen synthesis was decreased significantly in population Ⅳ, Ⅴ. Taken together, the increase of protein synthesis by PDGF in rat calvarial cells was due to the incraese of NCP synthesis.

To study the effect of cAMP on the generation of osteoclasts from their precursor cells, the bone marrow cells were isolated from 7 to 9 week-old male mice. The femur and tibia were dissected aseptically and the marrow cavity was flushed with 1 ㎖ of α-minimum essential medium by slow injection. Collected marrow cells were cultured at 1.5-2.0×10^6 cells/well in 24-well plate for 8 days. In experimental group, PGE_2(5×10^-6, 10^-5M), forskolin(10^-5M) or IBMX(10^-4, 10^-5M) were added singly or in combination from the 1st day culture. After cultures, staining for tartrate-resistant acid phosphatase(TRACP)-marker enzyme of osteoclast-was performed according to the modified method of Burstone. The TRACP-positive multinucleated cells(MNC), which have 3 or more nuclei, were counted. The observed results were as follows. 1. In control group. TRACP-positive mononuclear cells were present, but no TRACP-positive multinucleated cells appeared. 2. PGE_2(5×10^-6M) or forskolin(10^-5M) significantly stimulated the formation of TRACP-positive MNC. Moreover, forskolin potentiated the TRACP-positive MNC formation induced by PGE_2 when added simultaneously. 3. IBMX(10^-4, 10^-5M), when added alone, significantly stimulated the formation of TRACP-positive MNC. However, IBMX(10^-5M) added in combination of PGE_2(10^-5M) partially inhibited the TRACP-positive MNC formation induced by PGE_2.

Fluorination of drinking water has been used world widely to reduce the incidence of caries. Recently, contradictory results on the cytotoxicity of fluoride compounds are reported. In addition, there are attempts to use fluorosilicate for fuorination of drinking water in Korea, therefore, we tried to analyze the cytotoxicity of fluoride compounds on oral epidermoid carcinoma (KB and A253) and osteosarcoma (HOS and MG-63) cells in this study. We treated cells with 0, 10, 50 and 250 ppm of fluorosilicic acid (domestic or from Fluka, F_(6)H₂Si), sodium fluorosilicate (F_(5)Na₂Si), sodium fluoroacetate (FCH2CO2Na), sodium fluoride (NaF) or potassium fluoride (KF) and measured the relative cell survival by Mn' assay. At the concentration of C 10 ppm, no significant cytotoxicity was observed. At 50 ppm, each cells revealed different response to fluoride treatment. Among cells used in this study, MG-63 was the most resistant to fluoride treatment. Comparable toxicity data from domestic and imported fluorosilicic acids were obtained. When we compared the relative cytotoxicity of fluoride compounds against their fluoride contents, the differences in relative cell survival were smaller. Most of cells showed C 20% of survival at 250 ppm. In order to analyze the pH dependence of the cytotoxicity of fluorosilicates, the pH of cell culture media containing fluorosilicate was adjusted to 7.4 or 6.5 and the relative cytotoxicity was measured. At lower pH, about 10% higher cytotoxicity was obtained. Thus, our data suggested that the toxicity of domestic fluorosilicic acid was sirnilar to that of fluorosilicic acid from Fluka, and the cytotoxicity of fluoride compounds was dependent an the relative content of fluoride and pH.

원발성골림프종은 매우 드문 질환이기는 하나, 복합항암요법이나 방사선 치료등에 높은 반응율을 보이며, 좋은 예후를 가지는 림프절의 비호지킨 림프종의 일종이다. 그러나, 치료 효과 판정에 있어 골병변의 특이성에 의한 모호한 방사선학적 특징으로 어려움이 있어 왔다. 본 증례는 위와 같은 원발성골림프종 환자에서 PET 스캔을 사용하여 민감하게 완전 반응을 평가할 수 있었던 예로, 앞으로 다른 고식적인 방법과 함께 이 질환의 진단과 치료 평가 있어 유용하게 사용 될 수 있을 것으로 전망할 수 있었다. Purpose: Accurate assessment of the lesion after treatment of patients with bone lymphoma is difficult. In this patient who demonstrated complete remission after chemotherapy, the regions of fluorine-18 fluorodeoxyglucose (^(18)FFDG)PET uptake diminished more rapidly following therapy, indicating a complete response at much earlier stage than did Magnetic Resonance Imaging (MRI) or CT based findings. With the conventional methods, such as MRI and CT. It was difficult to assess whether the residual tumor tissue was viable or not. Decision to complete response is very important in patients with ymphoma to plan the further treatment. We experienced a patient with primary lymphoma of bone who revealed complete response to chemotherapy on ^(18)FFDGPET while CT showed persistent destructive bone lesion. Thus, ^(18)FFDGPET study after therapy may be superior to CT in the evaluation of response to treatment in primary lymphoma of bone.
