Background: Although deleterious effects of sunlight have been increased recently, the surveillance of the attitudes toward sun-exposure and the behavioral aspect of using sunscreens in Koreans has hot been carried out. Objective: Our purpose was to evaluate the attitude toward the harmfulness of sun-exposure and behaviors of using sunscreens in Korea. Method: Five hundred and fifty-two subjects were surveyed to assess the attitude toward sun-exposure, as well as the subjects knowledge about, and the use of sunscreens. Underlying data including demographic data, skin colors, skin types, occupation, and sun-exposure, were obtained. Results: Fifty-four percent of subjects believed that sun-exposure is bad for their skins, but, on the contrary, 12.5% believed it to be beneficial. Fifty-two percent of subjects used sunscreens. Almost all subjects(93.8%) knew why to use sunscreens but 62.7% of subjects did not know the meaning of sun protective factors(SPF). Women, indoor workers, subjects less than 40 years old, with less sun-exposed, fair colored skin, or with skin type I, II, III tended to know the deleterious effects of sunlight and the meaning of SPF and used more sunscreen. Conclusion: High risk population-men, outdoor workers, subjects oider than 40 years old, with more sun-exposed, dark colored skin, or skin type VI, V could be targeted with campaigns that promote attitudinal and behavioral changes.

Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

Dysplasia-associated seizure disorders are markedly resistant to pharmacological intervention. Relatively little research has been conducted studying the effects of antiepileptic drugs(AEDs) on seizure activity in a rat model of dysplasia. We have used rats exposed to methylazoxymethanol acetate(MAM) in utero, an animal model featuring nodular heterotopia, to investigate the effects of AEDs in the dysplastic brain. Pilocarpine was used to induce acute seizure in MAM-exposed and age-matched vehicle-injucted control animals. Field potential recordings were used to monitor amplitude and numbers population spikes, and paired pulse inhibition in response to stimulation of commissural pathway. Two commonly used AEDs were tested: diazepam 5, 2.5mg/kg;phenytoin 40, 60mg/kg. Diazepam(DZP) and phenytoin(PHT) reduced the amplitude of population spike in control and MAM-exposed rats. However, the amplitude of population spike was nearly eliminated in control rats as compared to the MAM-exposed rats. Pharmaco-resistance was tested by measuring seizure latencies in awake rats after pilocarpine administration(320mg/kg, i.p.) with and without pretreatment with AEDs. Pre-treatment with PHT 60 mg prolonged seizure latency in control rats, but not in MAM-exposed animals. The main findings of this study are that acute seizures initiated in MAM-exposed rats are relatively resistant to standard AEDs assessed in vivo. These data suggest that animal model with cortical dysplasia can be used to screen the effects of potential AEDs.

A clinic-and school-based fissure sealant program was initiated by the community health center in Habchon, Korea in 1996. Fissure sealants were applied limitedly to first molars of all 6-year olds, grade one of elementary schools in 1996. The program was expanded to more children annually by one grade. Children for sealants included all 6-10-year olds in grades one through five in 2000. The application of sealants was expanded to premolars besides molars. Children who lives close to health center or health sub-center visit the dental clinic of health center or sub-center by themselves for sealants. However, dentists and oral hygienists of health center or sub-center visits remote elementary schools and provide sealants at schools. To evaluate the effectiveness of a clinic-and school-based fissure sealant program in Habchon-gun, dental examinations were conducted on 6-14-year old 1,957 children of elementary and middle schools in Habchon-gun and control group, 1,277 children in 2000. The surveyed data were analyzed with SPSS statistical package. The obtained results were as follows; 1. DMF rates were 7.5% at &year olds and 53.5% at 6-and 10-year olds benefited by the sealant program of Habchon-gun Health Center, DMF rates in sealant group was lower than control group. 2. DMFT scores were 0.11 at 6-year olds, 1.33 at 10-year olds benefited by the sealant program of Habchon-gun Health Center. DMFT scores in sealant group was lower than control group. 3. The caries reduction rate from the sealant program was calculated as 56.0%, 31.4%, 43.1%, 28.9%, 30.4% at 6-,7-, 8-, 9- and 10-year olds respectively by the difference of DMFT scores between sealant group and control group. 4. Percentage of children with sealants was 52.8% and 95.5% at 6-and 10-year olds respectively. Mean number of teeth with sealants was 0.83 and 5.06 at 6-and 10-year olds respectively. 5. The fissure sealant program of Habchon-gun Health Center from 1336 to 2000 was evaluated to be effective to reduce dental caries on permanent teeth. These results substantiate that a significant reduction in dental caries can be achieved by the fissure sealant program.

In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

본 논문은 아스팔트 혼합물의 소성변형 저항성과 상관성이 높은 특성치를 찾고자 Kim test를 개발하여 현재 적용성 연구결과를 다루고 있다. 이 논문은 새로운 강도특성치인 변형강도(S_(D))를 개발하는 Kim, test 연구의 4단계 연구 결과이다. 13 mm 골재(편마암, 화강암)와 입도(밀입도, 갭입도) 5가지 폴리머로 제조한 8가지 바인더로 두 가지 입도에서 소성변형 저항성이 다른 32가지 혼합물을 만들었다. 슬래브(305㎜×305㎜×62㎜)공시체를 제조하여 한쪽은 Kim, test를 수행하기 위하여 18 cm정도로 잘라서 코어를 3개 채취하고 다른 한쪽은 12cm크기로 하여 반복주행시험을 실시하였다. Kim, test는 하중봉 3(0.75), 4(1.0)을 사용하였다. W/T시험으로부터 최종 침하 깊이와 동적안정도의 두 가지 소성변형 계수를 각 혼합물별로 구했다. 각 하중봉과 골재별, 입도별로 S_(D)와 소성변형 계수간의 통계적 상관관계 분석을 수행한 결과 S_(D)와 소성변형 계수와의 결정계수가 매우 높게 (R²>0.95) 나타났다. 하중봉 4(1.0)이 3(0.75)보다 다소 높은 상관성을 보였다. 향후 Kim test실험에서 하중봉 4(1.0)을 사용하고 4단계 방법을 이용한다면 소성변형 특성치인 침하깊이(DR)와 동적안정도(DS)와의 상관성이 매우 큰 시험법이 될 것이다. 또한 변형강도의 파괴 메커니즘은 콘크리트의 펀칭파괴와 유사하여 콘크리트의 전단강도 추정식을 근거로 아스팔트 콘크리트의 재료 특성에 적합한 추정식 계수 ◁ 원문 수식 참조 ▷ 를 얻었다. 이 식을 이용한다면 아스팔트 콘크리트가 견딜 수 있는 임계하중을 변형강도에 근거하여 추정할 수 있을 것이다. This study shows predictability of rut parameters of modified and unmodified asphalt concretes based on the deformation strength (S_(D)) which is calculated from the maximum load, deformation and size variables of loading head under simple static loading. This paper is the result of latest studies, phase 4 which is a part of Kim, Test studies for developing a new strength property for asphalt concrete. Two aggregates, gneiss and granite, two gradations, dense-graded, gap-graded, with maximum, size of 13mm and eight binders using different contents of five polymers (RLDPE, RHDPE, LDPE, SBS, SBR) were used to produce 32 different mixtures. A slab (305㎜×305㎜×62㎜) was cut into two pieces(18cm and 12cm width) and three 10cm cores were taken for S_(D) test from the larger piece and wheel tracking test was performed on the smaller piece. Kim test was performed using loading head 4(1.0), 3(0.75). Two rut parameters, depth of rut and dynamic stability, from the rut depth-cycle curve from a WT test were obtained for each mixture. Statistical analysis were performed for each loading head, aggregate, and gradation to find out correlation between S_(D) values and each rut parameter. The analysis results showed that S_(D) had high R² (over 0.95) on the average with rut parameters. The loading head 4(1.0) showed R² better than 3(0.75). It is concluded that S_(D) is the property that has excellent predictability for rut parameter of asphalt concretes. An equation, ◁ 원문 수식 참조 ▷ was obtained based on the equation of concrete shear load creating punching failure and current test data, because the failure mechanism of S_(D) is similar to punching failure of concrete. In the equation, P is shearing force creating punching effect, b is length of perimeter of punching area and d is depth of specimen. If this formula is used, a critical load for deformation failure will be predicted based on the S_(D).

The prevalence of PPNG among pretreated gonorrhea cases isolated at the STD clinic of Choong-Ku Public Health Center in Seoul has been studied and reported annually since 1981. In 1991, 123 strains of N.gonorrhoeae were isolated, among which 58(47.1%) were PPNG. In 1992, 98 starains of N.gonorrhoeae were isolated, among which 51(52.0%) were PPNG. In all, 109(49.3%) strains were found to be PPNG among 221 strains isolated between 1991-1992. The prevalence of PPNG in Seoul showed increased tendency till 1989, thereafter, it has been stationary or slightly decreasing.

빠르며 정확하고 안전한 치아이동을 목표로 삼고 있는 교정치료에서 최근 새로이 도입된 피질골 절제술과 견인 골형성술을 응용한 치아이동에 대하여 알아보았다. 특히 견치나 대구치의 후방이동은 기존의 치아 이동 양식으로는 조절이 어렵고, 장기적인 기간에 불가피한 치아이동이다. 피질골 절제술과 견인 골형성술을 동반하여 상당히 효과적인 원심이동을 기할 수 있었던 증례를 통하여 적용 술식, 견인 장치 등을 논하고 그효과를 파악하였다. 이런 술식을 통해 빠른 치아 이동과 이에 따른 전반적인 치료기간의 감소가 가능하였으며, 무리한 치아이동에서 발생할 수 있는 고정원 소실이나 치근흡수, 치주조직의 파괴 같은 부작용도 줄일 수 있었다. Tooth movement facilitated by corticotomy and distraction osteogenesis was discussed. In this study, a portion of cortical bone which can provide resistance to tooth movement in alveolar bone was removed. Active bone deposition was then possible in the tension side. Teeth moved at such a speedy rate as we could not imagine from conventional orthodontic treatment, which lead to the reduction of the total treatment period. Posterior movement of the canine or molar teeth was possible without any side effects such as anchorage loss, root resorption or periodontal breakdown.

Background and Objectives: Little is known about the effects of the implemented health information system. The purposes of this study were to examine the nurses' evaluation, satisfaction, and adaptation on order communication system (OCS) in a university hospital. Method: For this descriptive correlational study, data were collected from 185 nurses using a structured questionnaire. For data analysis, descriptive statistics, t-test, ANOVA, and Pearson's correlation analysis were used. Results: Nurses evaluated that the appropriateness of OCS was relatively low, but they reported that OCS had increased the efficiency of their work and quality of care they had been providing. The respondents' satisfaction and adaptation on OCS were relatively lower than those of previous studies. Nurses' satisfaction on OCS was significantly different by age and marital status. Older and married nurses reported higher satisfaction than their counterparts. Conclusion: There might be great needs to improve nurses' satisfaction and adaptation on OCS. OCS should be improved more user friendly and conveniently to increase users' satisfaction and adaptation. Moreover, comprehensive health information system including nursing information system needs to be developed.
