Long term occupational exposure to solvent mixtures may cause adverse effects to the central nervous system with neurobehavioral symptoms. And some organic slovents have been suggested to cause impairment of tuberoinfundibular dopaminergic activity and neurochemical mechanisms controlling pituitary secretion. For the purpose of assessing neuroendocrine effects in occupational solvents exposure, hormonal study settings (shoes-manufacturing industry & fishing products industry) and compared with nonexposed controls(33 men, 85 women). Male workers exposed to solvent mixtures had significantly lower plasma level of follicle-stimulating hormone(FSH) than nonexposed male controls. While female workers exposed to solvent mixtures had significantly lower plasma levels of growth hormone(GH), and thyroid-stimulating hormone(TSH) than nonexposed female controls. The results of significant decrease in plasma concentrations of pituitary hormones(FSH, GH, and TSH) in workers exposed solvent mixtures indicate that occupational exposure to solvent mixtures may induce neuroendocrine effects through an effect on hypothalamic pituitary axis.

Vascular lesions of the oral and maxillofacial area is interesting to clinicians because it is difficult in management and has poor prognosis. There have been attempt to classify vascular lesion and recently new classification is introduced that have two basic entities, 1) hemangioma, 2) vascular malformation. It is useful that evaluation of lesion, treatment planning and predicting on prognosis. But vascular lesion is still difficult to clinicians about treatment. A case of acidic cell carcinoma combined with hypervascularity arising on the hard palate in a 28-year-old woman is reported. We mistook it for vascular lesion because of hypervascularity. The clinical and histologic feature are described. Literatures about neovascularization of tumor & acidic cell carcinoma are reviewd, too. And we attempt to solve the problem of hypervascularity.

For each construction material used, there is certain theoretical limit in sizes. For tall building construction, the reduction in slab weight is the first step to take in order to break such size limits. In this paper, the feasibility of such objective is proven and given by numerical analysis result. For a typical building slab, both concrete and advanced composite sandwich panels are considered. The concrete slab is treated as special orthotropic plate to obtain more accurate result. Any method may be used to obtain the deflection influence surfaces needed for this vibration analysis. Finite difference method is used for this purpose, in this paper. The influence of the modulus of the foundation on the natural frequency is thoroughly studied.

As the society system becomes industrialized and urbanized, most seniors have been excluded from laboring and social participating compulsorily or voluntarily. Further more, the trend toward the nuclear family initiated by young generation has taken away even the role of them and gave them much leisure time. This leisure time is not the one which is given in the social and family role, but the one which is spent in vain without any given role. The purpose of this dissertation is to identify the effect of sport program for senior citizens in their leisure and life satisfaction. To achieve this purpose, the correlation between the existence of participation in the life sports and the leisure satisfaction of seniors and the correlation between the higher degree of participation in the life sports. The major findings obtained from this study were following. First, it found that participants in sport for all program of older persons showed greater leisure satisfaction than non-participants Second, the higher the frequency and duration of participation in sport for all program, the higher leisure satisfaction. Based upon these findings and within limitations of this study, it was concluded that participation in sport for all program of older persons would increase the leisure satisfaction.

The most of the design engineers for construction has academic background of bachelors degree. Theories for advanced composite sturcutures are too difficult for such engineers and soe simple but accurate enough methods are necessary. The senior athor has reported that soke laminate orientations have decreasing values of D?, B?, D? and B? stiffnesses as the ply number increases. Such plates behave as special orthotropic plates and simple formulas developed by the author can be used. Most of the bridge and building slabs on girders have large aspect ratios. For such cases further simplification is possibe by neglecting the effect of the longitudinal moment terms(M?) on the relvant partial differential equations of equilibrium. In this paper, the result of the study on the subject problem is presented.

목적 : 산업 장에서 노출되는 유기용제가 청력역치에 어떠한 영향을 미치는가를 5년 동안의 추적조사를 통하여 파악하고자 하였다. 방 법 : 유기용제와 소음에 동시에 노출된 근로자 43명과 소음노출수준, 연령, 근무경력을 짝짓기 한소음노출군을 대상으로 문진과 이경검사, 소음노출 수준, 유기용제노출수준을 조사하였다. 결과 : 1. 전체 근로자의 각 주파수별 청력역치 변화양상에서 500Hz∼2000Hz에서는 추적기간 동 소음동안 현저한 변화가 없었고, 4000Hz 및 8000Hz에서는 역치가 증가하는 경향을 나타내었다. 2.유기용제와 소음에 동시에 노출된군에서 소음 노출군에 비해 4000Hz 이상에서 청력역치가 높게 나타났으나, 통계적인 유의성은 없었다(p(0.05). 3.반복측정 분산분석 법으로 각 주파수별 평균청력 역치의 연차적 변화에 미치는 영향을 분석한 결과 유기용제 노출은 통계적으로 유의한 영향이 없었으나(p)0.05), 소음노출수준은 250Hz, 2000Hz 및 4000Hz에서, 연령은 250Hz와 500Hz에서 통계학적으로 유의한 영향을 미치는 것으로 나타났다(p(0.05). 4.소음노출군파 동시노출군 각각에서의 청력역치 변화량을 paired t-test로 비교한 결과 250Hz∼4000Hz에서는 통계학적 유의성이 없었으며(p(0.1), 8000Hz에서만 경계치 (p=0.0884)의 유의성을 나타내었다. 5.요인들의 영향을 보정한 상태에서 관찰하기 위해 관찰기간동안의 청력역치변화량을 종속변수로 두고 일반선형모형을 이용하여 주파수별로 관찰한 결과 8000Hz에서만 모델에 통계학적 유의성이 있었으며 (p(0.05), 여기서 소음노출수준이 통계학적으로 유의한 영향을 미치는 것으로 나타났고(p(0.05), 유기용제노출은 경 계수준이 었다(p=0.087). 결론 : 청력에 대한 유기용제의 영향이 소음과 연령에 비해 상대적으로 미미하여 명확한 결론에 이르지는 못하였으나, 다소 영향이 있는 것으로 생각되어 유기용제의 영향에 대한 추가연구가 필요할 것으로 판단된다. 또한 보다 효과적인 근로자들의 청력관리를 위해서는 소음 외 산업 장에서 동시에 노출되는 여러 유해물질들을 고려하여야 할 것이다. Objectives : This study was to evaluate the impacts of simultaneous exposure to noise and mixed solvents on workers'hearing threshold level (HTL) over five-year period. Methods : The study was conducted by interview and annual audiometric test on workers in ship building industry from 1994 to 1998. The cases(workers who exposed to noise and mixed solvent simultaneously) were 43 male workers and controls (workers who exposed to nolle) were selected by matching method with regard to age, sex, carrier, and noise exposure level. To assess the impacts of solvent exposure on hearing threshold level, with considering other factors, general liner model was used. Results : 1. The audiogram of all subjects showed typical sensorineural hearing loss pattern. The mean HTLe were increased at high frequency (4000HB and 8000Hz) for study period. 2. The HTLs of cases were more increased than those of controls at high frequencies (4000Hz and 8000Hz), but there was not statlstical significance. 3. The impact of age on the HTL was statistically significant at 250Hz and 500Hz (p(0.05), and the impact of noise on the HTL was statistically significant at 250Hz, 2000Hz and 4000Hz (p(0.05), but the impact solvent exposure on the HTL was not significant. 4. The changes in HTLs of cases were higher than those of controls at high frequency, there were not statistical significance at 4000Hz, but only at 8000Hz (p=0.087). 5. Statistical analysis of the general linear model implicated that the changes in HTL was impacted by noise exposure bevel significantly (p=0.031) and Impacted by solvent exposure weakly (p=0.087) at 8000Hz. Conclusions : The results of this study suggest that workers who simultaneously exposed to noise and mixed solvent were at risk for more affected HTL than those exposed to noise exposure only, but we could not find definitive evidence. Further detailed studies must be made in large number of workers.
