This study was conducted for the purpose of fin-ding out the variance explaining the medical facilities utilization behavior, which is defined adaptation behavior Process by focal, contextual, residual stimuli in Roy's Adaptation Model. What kinds of characteristics can explain adaptation behavior in Roy's Model? And which is the relative importance of input variables? For this analysis, stepwise multiple regression and path analysis was used. The data come from the 1981 Baseline Household Interview Survey in remote rural area. The findings of the analysis can be summarized as follows: First, Total variance of independant variables for adaptation behavior, that is medical facilities utilization including clinic, drug store, health center, herb medicine was shown 16.2 percent. The most important variable which explain the dependent variable was the occurance of illness with the Ra of value 0.112. The illness symptom, living level, regular care source was shown important variables with relatively high the R²value and significant beta coefficient. Second, in the path analysis of variables which is selected important variables, the occurance of illness was shown variable which has the highest direct effect which 0.297 path coefficient. Also the education level of household was shown variable which has the highest indirect effect through living level and the occurance of illness in causal model. Third, This analysis suggests that the occurance of illness belonging focal stimuli are more influenced than others. To sum up, It is seem to the occurance of illness, illness symptom belonging focal stimuli have high explanation ability through direct effect, education level of household among contextual stimuli have explanation ability through indirect effect.

In modular architecture, manufacturing drawing which includes whole information for modular unit production is essential since works for modular unit have to be performed in manufacturing factory not construction field. Although the manufacturing drawing is important as known it is insufficient to utilize the manufacturing drawing in modular architecture project and this makes modular unit low-quality with re-work and work time delay. To prevent low-quality modular unit caused by insufficient manufacturing drawing, in this research firstly manufacturing drawing's current situation and error cases in manufacturing phase of past modular housing project were analyzed, and correlation between reduction of errors occurance frequency and improving manufacturing drawing was verified. Secondly manufacturing drawing improvement factors were deducted in interior, furniture, mechanical work phase which errors' occurance rate is high and the way of deducting manufacturing drawing lists and contents were suggested with light-weight work as an example in case of new type of errors occurance. A series of research process can contribute to good-quality modular unit by errors reduction. As a result of research, about half of errors occurance can be reduced with suggested manufacturing drawing improvement factors. And the manufacturing drawing process can contribute to modular production which have uniform quality.

A series of studies were conducted to find out the effects of chemical composition in brown rice on the occurance of chalky grain in paddy soil which had been applied compost, lime and silicate fertilizer every year for 38 years. Effects of nitrogen fertilizer on occurance of chalky grain were greater in order of ammonium sulfate>urea>no fertilizer. The occurance of chalky grain was decreased by lime and silicate fertilizer application, but compost application markedly increased occurance of cralky grain due to increment of nitrogen uptakes. Rice quality tend to lower by increasing nitrogen uptakes whereas Mg/K and $Mg/K{\cdot}N$ ratio were reverse. It is considered that the occurance of chalky grain are closely associated with uptakes of nitrogen, magnesium and potassium.

An electrolytic silver plating process has been successfully developed for terminated electrode parts of dielectric ceramic resonator. High adhesion strength and high Qu is obtained and blister occurance is minimized under plating condition with $HNO_3$750 $m\ell/\ell$ and HF $ 250m\ell/\ell$ solution at $25^{\circ}C$ for 20 minutes. Adhesion strength has the highest value, 3.2 kg/mm$^2$ at etching temperature of $25^{\circ}C$. Adhesion strength, Qu and blister occurance are monotonically increased with the thickness of electrodeposition layer. In case of electrodeposition of Ag, Qu value of 380 has obtained higher than in case of electrolytic Cu plating with Qu value of 325. Therefore, terminated electrode parts of dielectric ceramic resonator reducing dielectric loss can be obtained using prensent process.

Objectives : This study is designed to find out if Sasang Constitution distribution is related to the additional effect occurance of Ring Moxibustion treatment. Methods : We choosed 59 case of 'deficient of Qi' patient from 300 using VEGA-D-F-M, then investgated for the additional effect of Ring Moxibustion treatment, to find out tendency with Sasang Constitution distribution. Results : 1. the additional effect was in 2 case of patient, redness and itching sign. Other was not observed. Occurance of Ring Moxibustion treatment is not related to Sasang Constitution distribution. 2. The 'deficient of Qi' case were numerous in Soin(少陰) Constitution then other, about half. Conclusions : This study shows that side effect of Ring Moxibustion treatment is not related to Sasang Constitution distribution.

Over 6 thousand workplaces in Korea are exposed to levels of noise which put their hearing of risk. Goverment considered various methods for noise reduction, but high noise breeds much problems still. This research investigates the present state of noise occurance and studied improvement way of administration system.

The main purpose of this study was to investigat and analyse the causes of occurance of industrial accidents in Korea. In the study all statistical data regarding dangerens materials or parts, injured positions, primary and secondly causes of accidents, and people's interest of safety, etc., were obtained from 1, 027 various industry which have move more than one hundred employees. Especially, in the study, I tried to grasp essential causes and tendencies of occurances of industrial accidents relased to the various situstions, and to set up preventive method and policies scietifically.

An expert system DESPRESS is developed to diagnose the fault of press by using CBR technique. In this paper, we describes the subjects for development of the system. DESPRESS deals compositly with perceptive symptoms, functional abnormalities, lamp signals and gage values, and then outputs fault parts and fault status for the press. The expert system can be used to prevent occurance of unexpected fault and minimize break times for failures.

Aluminum Alloys with a content of 22 wt.-% $Mg_2Si$ were spray formed. This alloy features by a low density and is therefore a superior material for leightweight applications. The main problem in spray forming of this type of alloy was the occurance of high porosities. First process optimizations have been performed to decrease porosity under a certain level, so that it can be closed by an extrusion process

This study was aimed to investigate the electrolytes and its relationship with acute stroke patients in each stroke type by case-control study. 217 patients with first-ever acute stroke within 2 weeks as the case group(Cases), 146 people without four major risk factors(hypertension, diabetes mellitus, hyperlipidema and ischemic heart disease) as the healthy control group(Normals), and 160 people as the general control group(Controls) were recruited at the Stroke Medical Center in Daejeon University Oriental Medicine Hospital from july 2005 to march 2007 for this case-control study. We analyzed the odds ratio of electrolytes in binary logistic analysis and evaluated each stroke type and general characteristics such as age, sex etc. The level of sodium(Na+) and potassium(K+) were significantly lower in LAA, SVO type of ischemic stroke and hemorrhagic stroke. But the level of chloride(Cl-) had no significant relation with stroke occurance. In this study we demonstrated that low sodium(Na+) and potassium(K+) have an influence on stoke occurance than chloride(Cl-). And we think that the electrolytes must be considered in risk factors of ischemic stroke in Korean and more prospective studies are needed.
