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.

The actual ground vibrations due to prism cut and trench cut blasting at power plant field have been measured, and the data were analyzed using reliability index(β) to the blast constants and attenuation coefficients. In this study, blast vibrations were suggested with wave component parts of ground vibration to the blast patterns, and were suggested with the division of ultimate limit state(,8 =0), serviceability limit state(β=1.28) and safety state(β =3) respectively. The reliability index 0 means 50% data line obtained by the least squares best-fit line. The reliability index 1.28 and 3 represent bounds below 90%, and 99.9% of the data, respectively. The vibration constants K(particle velocity) for prism cut were evaluated to 333, 619, 1419, respectively and the attenuation coefficients of vibrations was -1.94. From this study, inference and analysis methods of vibration equations using reliability theory were established.

The following results were obtained from the survey of health status and the measurements of physical fitness of 914 students of Ewha Womans University by means of CMI, which were conducted from October 7 to October 27 for three weeks. The purpose of the research mainly consists in the improvement of university health adiministration and of physical education. A. Survey of Health Status 1. The average Number of Complaints are 26.8 for items A-L, 15.3 for items M-R, and 42.1 for items A-R. In terms of classes, the Numbers of Complaints are revealed on a decreasing scale as follows: sophomores, 44.0, the highest; seniors, 42.6; freshmen, 42.1; and juniors, 40.5. 2. Among all the items, the following figures of average Numbers of complaints per person are conspicuous: the seniors have shown 5.3 for item D, which is the highest; and the sophomores, 0,7, which is the lowest. Among the physiological item, D, which corresponds to the ailments of digestion system, shows the highest rate; and among the items for mental diseases, item M, which corresponds to non­adjustment, is 5.2, the highest. 3.

The purpose of this study is to evaluate the shear strengthening effects of the iFREP(incombustible Fiber Reinforced Epoxy Panel) to the reinforced concrete members and to provide the basic design recommendation for shear strengthening. The main variable were the thickness of iFREP, the amount of stirrup and the type of strengthening. Thirteen specimens were tested under static monotonic loading. From the test results, it was shown that the failure mode of RC beams which are strengthened by iFREP was governed by the delamination of iFREP. The shear capacity of beams strengthened by iFREP can be determined as the summation of the shear strengths provided by concrete, stirrup, and iFREP The shear strength by iFREP should be calculated based on the effective strain of iFREP. Also, the shear strengthening effects of specimen with two-side bonded iFREP is similar to those of specimen with three-side bonded iFREP (U-TYPE).

As structures made of concrete are getting more high-rise and large-sized, it is necessary to fortify the concrete, the basic material of construction. Concrete's degree of strength is getting more improved due to these basic needs and researches on the subject are actively under way. This study is to predict mechanical behavior and fracture behaviors of high performance concrete. For that purpose, The writer fixed water-cementitious ratio at 33% and used finite element method based upon results of three-point bending tests by having six different types of test pieces with varying mixture ratio of silica fume, water reducer, and superplasticizer. With the finite element method, The writer compared the result of three-point bending test with fracture parameters which was acquired from nonlinear fracture analysis, from which mechanical behavior and fracture behavior of high performance concrete were predicted and usefulness of applied programs was verified.

Background : The survival benefit associated with first-line chemotherapy in lung cancer has led to the need for second -line chemotherapy, for which Docetaxel (Taxotere^(?)) has proven efficacy in both settings. This study evaluated the safety and efficacy of docetaxel in patients with non-small cell lung cancer who had failed first-line platinum-based chemotherapy. Methods : Thirty one patients with non-small-cell lung cancer, who had failed first line platinum-based chemotherapy, between March 1999 and August 2003, were enrolled in this study. Patients received intravenous docetaxel, either 75 mg/㎡ or 100 mg/㎡, with routine premedication every three weeks. Results : Fourteen patients (45.2%) had a partial response. The median survival and progression- free survival times were 12.5 months (95% CI 7.3-17.6) and 3.0 months (95% CI 1.6-4.5), respectively. This study showed 2 factors gave different survival benefits; the age (< 60 years: 20.1 months vs. > 60 years: 6.6 months, p=0.0105) and the histological type (adenocarcinoma: 25.6 months vs. others: 7.9 months, p=0.0055). The predominant toxicity was neutropenia, which occurred as WHO grade 3 or 4 in 38.7 % of patients. One treatment related death was also reported. Non-hematological toxicity was minor and easily controlled. There were no significant statistical differences in the survival benefit and toxicity between the two doses. Conclusion : Docetaxel, as second-line monotherapy, was well tolerated and effective in patients with non-small-cell lung cancer who failed first line platinum -based chemotherapy.

It studies the non-structural crack factors that are produced in Steel Box Girder Bridge concrete floor plate using analytical method. It mainly studies humidity and design standard of concrete strength. It used MIDAS CIVIL Ver 5.4.0, a general structure analysis program that applies drying shrinkage rate of domestic road bridge design standard and standard value of creep coefficient, CEF-FIP standard equation and ACI standard equation from the aspect of creep, drying shrinkage and hydration heat to see the effect of the two factors on concrete crack and found the following result. The analytical results of this study showed that the initial stress, which was obtained by ACI standard, exceeds the allowable tensile stress between 5 to 18 days. This result means that even if a bridge is designed and constructed according to design standard, the bridge can have cracks due to various variables such as drying shrinkage, hydration heat and creep that produce stress in slab.

We have analyzed the genetic relationship among the mouse strains using RAPD-PCR. Polymorphic RAPD markers amplified from various primers were used to analyze the genetic relationship among seven mouse strains, CBA, C57BL/6, BALB/C, NOD, A/wy, DBA2, and AKR. The genetic similarity coefficients were estimated using the RAPD markers by UPGMA method. The genetic similarity coefficient between CBA and NOD was 0.474. This value was lower than any other genetic similarity coefficient among the strains tested. And CBA-specific RAPD band patterns were observed in 5 primers from 6 polymorphic primers used. This study makes possible phylogenetic identification among the inbred mouse strains at the molecular level using RAPD-PCR techniques.
