重合體의 放射線 效果 : Polyethylene

盧鈑愚 全北大學校 文理科大學 1977 論文集 Vol.5 No.-

The radiation effct for polyethylene on the view of dynamical deterioration or mechanical characteristics is most practical. Howerer, the exisiting theories pertaining to any of subjects do not appear to have progressed enough to lead to a consistent interpretation of the observed phenomena. Thus we investigated the radiation effect for the samples(5^Mrad, 10, 15, 20^Mrad) being irradiated form Co^60 amd Ra-radiation.

The subject hospital is a Christian health care institution which is a 720 beds university hospitals and has been providing health care services and outpatient services located in Pusan, since its foundation in 1950. The purpose of this study is to develop marketing strategy for this University Hospital by identifying factors associated with the patients' attitudes toward their choice and images, with following objectives: 1) to identify patient choice factors 2) to analyze patients' images toward the hospital 3) to compare above informations with other hospitals in Pusan, and 4) to analyze population served with demographic and economic variables. The survey data retrieved from the samples of 140 outpatients and 100 intelligents were analyzed by Chi-square and Mann Whitney U test with the confidence level at less than 0.05. Major findings from the study were as follows: 1) Hospital choice motivation factors a. fovorable factors toward the choice of hospital revealed: (1) good facilities and equipments (50.2%) (2) large hospital (38.4%) (3) recommended by neighbor (35.0%) 2) Hospital image factors a. favorable factors: (1) modern equipments and technology sufficiency (2) friendliness of office employees (3) kindness of doctors b. unfavorable factors: (1) high cost of care (2) long waiting time for clinic examinations and prescription filling (3) traffic inconveniency 3) Comparisons with other hospitals showed disadvantages in the areas of: (1) inpatients are more favorable than outpatients toward good facilities and equipments, friendly doctors and nursing personnel, compared to the (2) unfavorable attitudes toward the long waiting time and impolite nurses, cleanliness, parking space shortage, etc. In reviewing the marketing information analysis, the hospital should carefully review the result, and endeavor toward the improvement of hospital services as well as image building, in regard to those areas showing negative results, in the marketing and strategic planning efforts with unified supports from the entire staffs and employees of the hospital.

The average behavior of the angular distribution of charged shower particles of 589 jets of 400GeV protons is shown to be well characterized by parameters of N_h, the number of heavy prongs, N_s. We substitutedθ, N_h, N_s, n_s into [≪ηθ≫-η_p/2]=F(N_h, N_s/<n_s>) and arranged the results of data and drew the figures of them.

Phthalates are used as plasticizers in PVC (polyvinyl chloride) plastics. As the phthalate plasticizers are not chemically bound to PVC, they can leach, migrate or evaporate into indoor air and atmosphere, foodstuff, other materials, etc. Consumer products containing phthalates can result in human exposure through direct contact and use, indirectly through leaching into other products, or general environmental contamination. Humans are exposed through ingestion, inhalation, and dermal exposure during their whole lifetime, including intrauterine development. And phthalate esters have adverse effects on liver, kidney, and the reproductive system, and act as weak endocrine disrupting agents. Expecially, university students have many opportunities to come in contact with the products included phthalate during the campus life (food packaging, body care product, cosmetic, lotions, aftershave, perfume etc). The purpose of this study was to examine the principles and methods of phthalate exposure. Because everyone used to PCPP (pharmaceuticals and personal care products) including phthalates and do smoking or drinking or eating.

CdTe thin films were grown by vacuum evaporation method. The polystalline structure of these compounds determined by X-ray diffraction analysis was cubic structure with lattice constant a_o=6.474A. Electrical resistivity(ρ), Hall mobility(μ_H), Hall coefficient(R_H) and carrier concentration(n) measured by Hall effect of CdTe thin films which baked at 360℃ ambient Ar-gas were given ρ=1.046x10^-1Ωcm, μ_H=0.241x10^3cm^2/v·sec, R_H=0.252x10^2cm^3/coul., n=2.918x10^17cm^-3, respectively. CdTe thin films had allowed direct transitions and optical energy band gap measured to be 1.501 eV at 288K.

본 연구는 1%Cr-Mo-V강 회전자축의 보다 개선된 크리이프특성을 위한 최적열 처리 조건의 선정과 크리이프 수명을 예측하기 위하여 행해졌다. 실험결과 970℃∼980℃ 퀜칭/660℃∼680℃ 템퍼링의 조합에서 최적크리이프 특성치가 나타났다. 또한 Larson-Miller법 및 Curvelinear Regression법에 의해 1%Cr-Mo-V강 회전자축의 주파단곡선을 구하였다. 회전자축이 530℃에서 연속 작동되며 순수크리이프 변형만을 고려할 때 회전자축의 최고응력 집중부에서의 예상크리프수명은 21.9×105hrs이었다. This study was carried out to find out optimum heat treatment conditions for improved creep properties and to estimate creep life of 1% Cr-Mo-V-steel rotor shaft. The effect of heat treatment on the creep properties of 1% Cr-Mo-V-steel rotor shaft was investigated under the conditions of various heat treatment temperatures. Experimental result shows that the best combination of quenching and tempering temperatures for good creep properties is 970℃-980℃ quenching 660℃-680℃ tempering sequence. A master curve for 1% Cr-Mo-V-steel rotor shaft was obtained by Larson-Miller parameter and curvelinear regression method. Life prediction at the maximum stress concentration points in the rotor was computed about 21.9×10??hours, if the rotor shaft would be continuously operated at 530℃ and be influenced by the effect of creep strain only.

In this study, 600 amateur marathoners participated in three national events were divided into two groups, sports massage applied group and non-treated group, to investigate the effect of sports massage on their performance, injury prevention and recovery. Results showed that; 1) sports massage group showed more completion numbers than non-treated group, 2) the records were better in sports massage group, 3) sports massage made the fatigue feeling period after running shorter, and 4) sports massage helped the participants sleep better at the event day night. So, it can be concluded that taking spore massage may have a certain level of benefits on the better performance, injury prevention, and recovery from fatigue. From these facts, the following suggestions are possible; 1) more specific way of sports massage needs to be developed for some specific events, 2) the scientific mechanism of how sports massage works, 3) systematically trained sports massagists are needed.
