The primary objective of this study is to investigate factors and variables which have significant effects on user satisfaction with recreational facilities in Children's Grand Park in Pusan City, theregby to establish the developmental way of urban park and open space. To test the causal models of this research, the data were gathered by self-administered questionnaires from 1085 households in Pusan City which were selected by the multi-stage probability sampling method. The analysis of the data primarily consists of two phase : The fist analysis dealt exploratory factor analysis which identified major factors involved in satisfaction with recreational facilities in Children's Grand Park and the second analysis tested the fit of the causal models of this research by employing LISREL methodology. The factor analysis identified that five factors are involved in satisfaction with recreational facilities. The five factors of satisfaction with recreational facilities are convenience and maintanance facilities, learnded recreational facilities, spaces for repose and relaxation, spaces for active recreation failities, and facilities for health and physical facilities. The second phase analysis tested the fit of the causal models for satisfaction with recreational facilities to the data and identified statistically significant causal linkage among overall satisfaction with Children's Grand Park, other endogenous factors and exogenous variables. Overall fits of both causal models were very good. Among endogenous factors, facilities for repose and relaxation, facilities for convenience and maintenance, learnded recreational facilities were identified as having significant effects on overall satisfaction. Exogenous variables which have significant effects on endogenous variables were also identified. These significant relationships indicate important factors and variables that should be considered in planning and development of urban park and open space. On the basis of these significant causal relationships, way for delovepment of urban park and open space were suggested.

Diterpenoid 생합성의 중요한 전구체인 geranyl­g geranyl pyrophosphate의 공급을 위해 외부에서 geraniol을 넣어 주었을 때 taxol을 포함한 일부 taxane의 생산이 증대 됨을 알 수 있었다. 또한 투여 시기와 투여량에 따라 결과가 크게 변화하였다. Camphor와 menthol은 taxol과 같은 terpenoid 계열의 물질이지만 외부에서 공급하였을 때에는 taxol 생산을 증대시키는 효과는 없었다. 외부에서 인위적으로 taxol과 cephalomannine, baccatin ill 를 공급했을 때 모든 경우에서 taxal 생산은 자극받지 않았으며 taxal을 공급했을 경우에는 bacca tin ill 의 생산이, cephalamannine을 공급했을 경우에는 7 -epl- 1 Q-deacetyltaxol의 생산이, 그리고 baccatin ill을 공급했을 경우에는 10-deacetyltaxol의 생산이 각각 가장 많이 중대하였다.

The prediction of dam inflow rate is crucial for the management of the largest multi-purpose dam in South Korea, the Soyang Dam. The main issue associated with the management of water resources is the stochastic nature of the reservoir inflow leading to an increase in uncertainty associated with the inflow prediction. The Autoregressive (AR) model is commonly used to provide the simulation and forecast of hydrometeorological data. However, because its estimation is based solely on the time-series data, it has the disadvantage of being unable to account for external variables such as climate information. This study proposes the use of the Autoregressive Exogenous Stochastic Volatility (ARXSV) model within a Bayesian modeling framework for increased predictability of the monthly dam inflow by addressing the exogenous and stochastic factors. This study analyzes 45 years of hydrological input data of the Soyang Dam from the year 1974 to 2019. The result of this study will be beneficial to strengthen the potential use of data-driven models for accurate inflow predictions and better reservoir management.

Pruritus is [CHECK DEFN] itchy feeling of one's skin. We often face stroke patients who complain about Pruritus. They occasionally fail to fall asleep or have a secondary infection as a result of scratching. For these reasons, severe Pruritus brings down general condition and interferes with recovery. The causes of Pruritus are distributed to from skin diseases and from internal diseases. Especially among the skin diseases, Xerotic Eczema, which is called Senile Eczema causes the dry skin in the elderly, especially lower limb's extensor part. According to the epidemiology, 20% of the old have Xerotic Eczema. In oriental medicine, Pruritus is called Pungsoyang(風瘙痒), Pungyang(風痒), Yangpung(痒風), Sinyang(身痒). The cause of Pruritus is divided into two. One is endogenous factors and the other is exogenous factors. The former are deficiency of blood(血虛), blood fever(血熱), wind-heat due to internal damage(內傷風熱), damp-heat in the liver and gallbladder(肝膽濕熱), endogenous wind stirring in the liver(肝風內動), deticiency syndrome of the spleen(脾虛), deficiency of Yin of the liver and kidneys(肝腎陰虛) and deficiency of the Penetration and Conception Vessels(衝任不足). The latter are wind-cold due to exogenous affection(外感風寒) and wind-heat due to exogenous affection(外感風寒). We report two stroke patients who complained of severe Pruritus They were diagnosed as having Xerotic Eczema by a dermatologist. We regarded their Pruritus as blood fever(血熱) and wind-heat(風熱) and prescribed Sopung-San to these patients. These patients showed significant improvement.

In the atherosclerotic subjects, arterial endothelial cell injury and plaque formation are suspected to be strong causable factors in developing acute coronary syndrome, and it was revealed that platelets have a very important role in this case. Women are exposed to atherosclerosis at a different degree after menopause or oral contraception. The purpose of this study was to determine the effects of endogenous and exogenous estrogen on the degree of platelet aggregation in platelet rich plasma(PRP) in twenty nonsmoking healthy Korean women for 12 weeks. The subjects were assigned to three groups: (1) eight women aged 49 to 60(yr) for the postmenopausel(Pst) group, (2) eight, aged 22 to 30(yr) for the premenopausa(Pre) group, (3) four, aged 23 to 30(yr) for the oral contraceptive (OC) group which used triphasic OC formulation. Fasting blood sample were obtained from the subjects, (1) once per 6 weeks in the Pst group, (2) every phase of the menstrual cycle in the Pre group, (3) each once during and after OC administration in the OC group. ADP, collagen and epinephrine were used as aggregating reagents, and platelet aggregation and time(Δt: time reaching to the maximum point of aggregation) in PRP were measured at the maximum point of aggregation in five minutes. All the data were adjusted for dietary effects, personality type and body mass index(BMI) by using analysis of covariation(ANCOVA). Platelet aggregation to ADP and collagen(MADP and MCOLL) were not significantly different among the three groups, and Δt to ADP and collagen(TADP and TCOLL) were not either. But maximum platelet aggregability and Δt to epinephrine(MEPIN and TEPIN) were significantly different among the three groups, and the OC group showed the lowest value (p<0.01). Maxtimum platelet aggregability and Δt during the menstrual cycle were not significantly different in the Pre group. Any other significant differences in the maximum platelet aggregability and Δt were found between oral contraception phase and washing out phase(menstruation) in the OC group. In results, maximum platelet aggregability and aggregation time to ADP and collagen seemed not to be affected by endogenous and exogenous estrogen, even though MEPIN and TEPIN showed significantly low in the OC group among the three groups.

In recent years, there were frequent exogenous contagious diseases in Eastasia like SARS(severe acute respiratory syndrome), Avian influenza, Swine influenza, MERS etc. But there are various interpretations about their pathological differentiations and lead to controversy to diagnosis and medicinal use. So there needs universal and consistent understanding methods. Several conclusions are obtained from the research on differentiation theories of various epidemic diseases. Essential elements of differential diagnostic system are pathogen, characters and matters of disease and loci, especially three yin and three yang has close affinity with constitutional features or body shape. Binding these 3 categories, an integrated differentiation 3 dimensional coordinates are made. Out of these, each elements of 3 pathogen-axial lines are related with names of exogenous disease, and those of 3 feature-axial lines are related with 8 principal patterns. And those of 3 locus-axial lines implicating therapeutic method are related with steps and location of exterior and interior, 3 yin 3 yang, Defense, Qi, Nutrient and Blood, five viscera and six bowels and tissues. Additionally, 3 lines of each axis consist of factors which have their own affinity each other, so classification of pathogen, feature, locus of disease has layered interconnectedness. This classification system is included in constitutional features of individual patient. Afterwards, these cognitive structure can be used as a general theory guiding method of therapy, prevention and aftercure healthcare.

The main current in the pathology of oriental medicine is composed of etiologic factor, pathogenesis and clinical manifestation. The access of a disease is consist of etiologic factor, location of the lesion, nature of the disease and patient's condition. The nature of disease and the property of a drug are inseparably related to each other. The nature of disease is composed of six exogenous factors, cold and heat, deficiendy and excess, Yinyang and pain. Cold nature is divided into cold symptom due to excess and asthenia cold, fever nature is divided into sthenic fever and asthenic fever. According to the location, cold and heat can be subdivided into heat in the upper and cold in the lower, cold in the upper and heat in the lower, exterior cold and interior heat, exterior heat and interior cold. Yin syndrome characterized by hypofunction of the viscera is generated from insufficiency of yang-qi, excess of yin-coldness, deficiency of both qi and the blood.

Digital knowledge and information goods as experience goods have some unique characteristics such as close to zero reproduction and distribution cost, high price volatility, and low price acceptability. For the reasons, the pricing policies of digital knowledge goods are very difficult and complicate. Also, most consumers of digital goods have experienced cognitive dissonance after buying decision. The purpose of this paper is to investigate what factors affect the price acceptability level and cognitive dissonance of digital knowledge goods buyers. This paper suggest a structural model that was established by the cognitive dissonance theory and S-O-R(Stimulus-Organization-Response) model. The model is consisted of four exogenous variables and three endogenous variables. The empirical test and statistical analysis suggest following results and practical implications. The variables such as product involvement and perception of price fairness that have positive roles to price acceptability have strong influence on the all the three endogenous variables. But the variables such as sale proneness and price mavenism that have negative roles to price acceptability have little influence on the all the three endogenous variables. In the model, the payment intention was very important mediating variable between exogenous variables and two dependent variables, ie. price acceptability and cognitive dissonance. These results imply that the digital knowledge portals must have some differentiated pricing policies to the customers who have price consciousness and price mavenism. Also, they need some special promotions to whom have positive attitude to the value of digital goods.

우리나라의 교통사고 발생현황은 2008년 기준 215,822건으로 예년에 비하여 소폭 감소하는 추세이나 주요 선진국에 비해서는 여전히 높은 수준이다. 그 중 단속류 시설에서 발생하는 사고는 보행자들이 직접적으로 차량에 노출되어 차대사람 사고의 비율이 높아 심각한 결과를 유발하기 때문에 이를 방지하기 위한 추가적인 고려가 필요하다. 이에 교통사고의 유형별로 영향을 미치는 인자를 분석하였다. 단속류 시설에서 교통사고는 크게 차대차 사고와 차대 사람 사고로 그 성격과 특성이 구분될 수 있다. 따라서 교통사고 유형을 크게 두가지로 구분하고, 2005년부터 2007년까지 서대문구에서 발생한 교통사고 자료 분석을 통해 교통사고의 심각도와 외생적 변수들간의 관계를 추정하였다. 본 연구에서는 단속류 시설에서 교통사고 유형별 요인을 구조방정식모형(SEM : Structural Equation Modeling)을 이용하여 도출해내고, 모형을 구축하여 유형별로 사고의 주요인들을 파악하여 비교하였다. 최종 모형에서 도출된 결론은 차대차 사고에서는 도로 요인이, 차대사람 사고에서는 환경 요인이 크게 영향을 미치고 있는 것으로 분석되었다.

Small and Medium sized hospitals are exposed to severe managerial environments recently. Around 8.0% of the hospitals are bankrupted every year. The adverse managerial environment does not only come from external factors such as patients' preference for larger hospitals, regulations on the medical charges; more serious problems come from the way the medium and small sized hospitals deal with those exogenous changes including lack of management skills, lack of change management skills, lack of managerial decision support systems, etc. This paper aims to support managers to make decisions regarding the exogenous changes. This paper can be interpreted as an attempt of a merge of the two techniques; BSC and system dynamics. Starting with a BSC system, the development of a system dynamics model can take advantages of the BSC information.
