일상생활에서 모발염색은 흔히 접할 수 있는 미용의 한 종류로 특히 젊은층을 중심으로 폭발적으로 유행하고 있다. 염색을 위항 사용하는 약제는 표백제와 발색제 등 각종 화학약품이 사용되고 있으나 이로 인한 건강장해에 대한 연구는 그리 많지 않다. 저자들은 염색이 인체의 모발건강에 미치는 영향을 파악하기 위하여 염색과 관련된 주관적 증상과 모발의 변화에 대한 실험적 연구를 시행하였다. 동국대학교 경주 캠퍼스 재학생 80명을 대상으로 설문조사를 시행하여 염색 유 ·무 및 염색 후에 경험한 증상에 대해 설문 조사하였고, 의과대학 재학생 46명을 대상으로 피부 반응 테스트를 실시하였다. 또한 염색 전후의 모발 탄성도를 측정하였고 모발의 상태를 파악하기 위해 전자 현미경검사를 실시하였다. 설문조사 결과 염색 전에 비하여 염색 후 안구혼탁, 안구건조, 시력저하, 발진 및 접촉성 피부염, 모발손상, 모근손상 등의 증상을 더 많이 경험한다고 호소하였다(p<0.05). 모발손상과 모근손상은 헤어드라이어 사용 빈도에 따라 증가하는 것으로 조사되었다(p<0.05). 피부반응검사에서 가려움증이 가장 많은 증상이었으며 이는 여성보다는 남성에서 높은 것으로 조사되었다. 염색 전후의 모발장력은 염색 전 134.5±10.37g, 염색 128.0±30.69g, 염색 이틀 후 112.5±19.69g으로 나타났다. 염색 전후의 모발의 전자현미경 케라틴 층이 현저히 감소하고 모발이 가늘어지는 차이를 보였다. 염색은 모발손상, 모발 케라틴 손상 및 모근 손상, 발진 및 접촉성 피부반응, 안구혼탁, 안구건조, 시력 저하를 유발한다. 따라서 염색약으로 인한 손상에 대한 주의와 예방이 필요하다고 생각한다. 예방대책으로 염색 전 피부테스트를 통한 적합성 여부를 판단하는 것이 필요하며 가급적 염색을 피하는 것이 좋을 것이다. 염색약에 발암물질이 포함되어있다는 보고도 있어 염색 제조사의 철저한 실험과 염색 물질의 선별이 염색으로 인한 부작용을 최소화하는데 중요한 역할을 할 것이다. Hair coloring has became one of the most popular cosmetic activities to younger generations during last decade. However, there are few studies on the health effect of widespread use of chemical dyes. This study was conducted to study the effects of hair coloring dye on hair and other systems. We conducted a questionnaire survey of 80 persons in Kyongju campus, Dongguk University. We have done open patch skin test on 46 medical students. We also conducted scanning electron microscopy to examine the hair strength and structure before and after hair coloring process. Injury of hair and hair bulb, contact dermatitis, turbid eyes, xerophthalmia, and poor visual acuity were the main symptoms complained after hair coloring (p<0.05). Injury of hair and hair bulb were increased by frequency of hair-dryer use(p<0.05). In open patch test, pruritus was complanined by more than half of the subjects. Mean strength of hairs before and after hair coloring was as follows; 134.5 (SD 10.37)g before hair coloring, 128.0 (SD 30.69)g immediately after hair coloring, and 112.5 (SD 19.69)g after two days. The scanning electron microscopic findings of hair surface before and after hair coloring showed decreased keratin layer and thinning of the hair. Hair coloring induces injury to hair, its keratin layer, and hair bulb as well as contact dermatitis, turbid eyes, xerophthalmia, and poor visual acuity. Therefore, we think that precaution is needed in use of hair coloring dye. To prevent complications induced by hair coloring dye, it is necessary, especially to those with allergy or skin disorders, to perform skin test before action and avoid hair coloring whenever possible. Longterm health effects of hairdye should be studied and manufacturing companies should try to minimize complications induced by hair coloring dye.

First all, the task should be performed at the level of strong over all policy, formulated by the government with special concerns at following points ; enlightment of people for the sports for all, development and popularization of various sports for all program, expansion of sports for all facilities, ensurance of sports for all directors, and their activities. The athletic policy should be performed as the followings. 1. Athletic policy should be performed as the fellowing in order that the promotion of sports for all may leads to prosperity of nation. The sports program for the people and its exciative scheme should be examined politically at the level of government. 2. Legislational complements in social sports is needed ; a provision, saying that the nation should promote sports for all, should be inserted to the constitution. Social sports promotion law is to be established and the national sports promotion law is to be reexamined. 3. National budgetary allocation for sports for all should be increased to fix the excited sports for all activity. In order to achieve the purpose, utilization of wnused space which is to expand sports for all facilities, encouragement of setting up private ones, and efficient management of the ones are the essential tasks. 4. To bring up sports for all leaders, a special qualitying hence should be given to the sports for all majoring man who has mastered required training at Athletic college. 5. We should contribute not only to activity sports for all but also to ensure elite sportmen by activate basic sports like field and track events, swimming, gymnastics, and traditional folk games. 6. The expansion of sports for all facilities is absolutely needed. So we should place the olympic facilities under public manaagement and retain relationship and contact between private sports facilities should be utilized both in elite sports and sports for all. 7. Masscommunications are expected to play stronger power in 2000. The role of Masscom is more to be complemented to balance the sports developments and then to popularize the national sports. 8. Cultivation of expert athletic administrator as well as reorganization or reinforcement of Athletic association is needed to develop the physical Education sports for all and elite egually. 9. Setting up the sports facilities in apartment area should be obligated and a space, the meeting point of inhabitants offered. 10. It is well known that sports has been exclusive to the players, and special class. The peoples misled recognition and valuation of sports should be overcome by various information activities. By doing so, we can lead peple to spontaneous and autonomous participations in sports.

이관영,박상현 大邱大學校 科學技術硏究所 1998 科學技術硏究 Vol.5 No.3
We did biological treatment experimentation of the Anaerobic digestion of the factory sludge including highly concentrated SO₄²- after we mixed 10% night-soil with that sludge. We analyzed and investigated the results and then we could have the conclusions as follows 1. In the continuous experimentation in which the digestion temperature read 25±1℃, the removal rate of COD and VS was 41% and 39% each in case of the digester with the only factory sludge. But the result was different in the event of the mixed sludge with 10% night-soil. The removal rate of COD was 44% and that of VS, 45%, And the quantity of gas generation was 1,120㎖ in the only factory sludge, but 1,430㎖ in the mixed sludge with 10% night-soil, that is, the former generated 4.1㎖ time more gas than the injection quantity, the latter, 5.2 times more. 2. In the continuous experimentation at the digestion temperature of 35±1℃, the removal rate of COD and VS was 41% and 37% each in case of the digester with the factory sludge only. But in case of the mixed sludge with 10% night-soil, the removal rate was 44% and 45% each. And the gas generation quantity was different in each case. In the single sludge digester, the quantity was diferent in each case. In the single sludge digester, the quantity was 570㎖, but in the mixed sludge digester, the quantity was 760㎖. That means that the former generated 2.1 times more gas than the injection quantity and the latter, 3.0 times more. 3. Through the experimentation of the treatment of the mixed factory sludge including highly concentrated SO₄²- with 10% night-soil, we could see not only the improvement of treatment efficiency but also the remarkable increase of the generation quantity of Methane. Accordingly we could have the conclusion that this kind of mixed treatment of the factory sludge with night-soil would be very efficient.

이관영,박상현 대구대학교 과학기술연구소 1998 科學技術硏究 Vol.5 No.4
After analyzing waste water sludge quantities of 3 types of waste water treatment plants operated in Taegu area(Dd, Df and S-treatment plants) on the basis of BOD, COD and SS, we could have the results as follows 1. The average inflow quality in the Df-treatment plants tends to be better 1.8 times than in the Dd-treatment plants and 3.1 times than in S-treatment plants. 2. The inflow characterisics of each season sustain the same tendency in all the types of treatment plants except m Df-treatment plants. On the whole, the inflow characteristics during March through May tends to be worse while they tend to be better during July through September. 3. The concentration loading of inflow in Df-treatment plants is more than in the other two types of plants. According to our survey, the concentration loading of inflow was 34,740(kg·BOD/d) in Df-treatment plants, 21,876(kg·BOD/d) in S-plants. 4. As to the dry sludge quantities with relation to each inflow property, we checked up BOD and SS. The result was that BOD was 0.915kg per lkg of inflow and SS was 0.369kg per lkg of inflow in Df-treatment plants. In case of Dd-treatment plants, BOD was 0.367kg and SS was 0.293kg. BOD was 0.399kg and SS was 0.293kg in S-treatments. 5. When we made a regression analysis of the dry sludge quantities of BOD and SS, we could find the dependability was over 90% in all the plants. So we can see that there is a close relation between inflow quality and sludge quantity.

고현정,정관희,임성삼 大韓齒科保存學會 1998 Restorative Dentistry & Endodontics Vol.23 No.1
This study was designed to examine the tissue levels of interleukin-1α(IL-1α), interleukin-1β(IL-1β) and tumor necrosis factor-α(TNF-α) in inflamed human dental pulps and periapical lesions, and to determine the relationship between each cytokine and pulpal and periapical pathosis. The pulps used in this experiment, were obtained in routine endodontic treatment and the periapical lesions in periapical surgery after clinical diagnoses were performed. These specimens were divided into four groups as normal pulp group(control group, n=9), acute pulpitis group(n=9), chronic pulpitis group(n=10) and periapical lesion group(n=18) and stored in liquid N_2. For extract preparation, tissues were finely minced with a scalpel, and the fragments were incubated in 0.5㎖ homogenizing buffer (0.1 mol/L potassium chloride, 0.02 mol/L TRIS; pH=7.6) for two hours and grinded with glass homogenizer. Debris was removed by centrifugation and supernatants were immediately tested with enzymelinked immunosorbent assay(ELISA, R&D Co., Minneapolis, USA). Following results were obtained ; 1. The concentrations of IL-1α in all experimental groups were significantly higher than in control group(p<0.05). And the concentrations of IL-1α in periapical lesion group were somewhat higher than in two pulpitis groups, but the differences among those groups were not stastically significant(p>0.05). 2. The concentrations of IL-1β in all experimental groups were significantly higher than in control group(p<0.05), and all the experimental groups expressed similar concentrations. 3. The concentrations of TNT-α in all experimental groups were higher than in control group but only the differences between chronic pulpitis group and control group were statistically significant(p<0.05). And the concentrations of TNT-α in acute and chronic pulpitis groups were higher than in periapical lesion group but only the differences between chronic pulpitis group and periapical lesion group were statistically significant(p<0.05). 4. There was significant correlation only between IL-1α and IL-1β in periapical lesion group(p<0.05).
