The purpose of this study is to find Korean tradition of residential space which continues since 1960s. Analysis of house works of contemporary architects on the foundation spatial characteristics of Korean. Traditional residence show that the trend and methods of embodiment of tradition in present architecture. The result of analysis could be summarized as follows. First, most of contemporary architects separate a house into two Chae-An Chae and Sa Rang Chae. Second, spatial flows in contemporary house works are very active through transition spaces just as traditional residence. Third, positive An Ma Dang takes on introversion, extroversion and continuity of space and also plays an important role in a house.

The dynamic characteristics of a continuous MMA/MA free-radical solution copolymerization reactor were studied. A mathematical model was developed and kinetic parameters which had been estimated in the previous work were used. With this model, bifurcation diagrams were constructed with various parameters as the bifurcation parameter to predict the region of stable operating conditions and to enhance the controller performance. It was shown that the steady-state multiplicity existed over wide ranges of residence time and jacket inlet temperature. Periodic solution branches were found to emanated from Hopf bifurcation points. Under certain conditions isola was also observed, which would result in poor performance of feedback controllers.

It is commonly known that upper class house in Chosun Dynasty has characteristics of connecting space in combination with 'Chae' and 'Madang'. But living territory of traditional residence is connected each other by means of the necessity of dwelling life. So, it can be a fragmentary understanding about traditional houses to consider it as connecting space only from the viewpoint of visual perception. Residential space in later Chosun Dynasty is affected by practical life-style rather than building principle of 'Confucianism' due to the erosion of the caste system and the spread of the modern residential culture. So, it is necessary to consider dwelling life at that time in order to understand spatial characteristics of the residences. Researcher made an assumption that these characteristics were observed in the emerging upper class houses which appear in the process of change of the caste system rather than the traditional upper class houses. The researcher investigated connecting space from 'Bakat-ma-dang' to An-ma-dang of the emerging upper class houses in Gyong-gi province. The goal of this study is to find the properties of connecting space related to dwelling life of the emerging upper class houses in Gyong-gi Province. With this study, the followings are the characteristics of connecting space in emerging upper class houses in later Chosun Dynasty. First, 'An-ma-dang(Courtyard)' comes into close contact with 'Bakat-chae(Outer quarters)' which accommodate the complex functions, 'An-ma-dang' plays an mediating role between 'An-chae' and 'Bakat-chae' Second, 'Bakat-chae' generally encases 'An-ma-dang' which is central territories of dwelling life, and the men's area of 'Bakat-chae' considerably has opening space towards the outside. Third, 'Anmadang' plays an mediating role of male's and female's living territory, and it plays an important role in connecting space where labor forces are concentrated.

Lee Je-Ma's theory claimed Xin(心) as Qi(氣). But he also described Xin as Taiji(太極) in the center as if Xin combines LI(理) and Qi. Taiji is meant to be a residence of the body, but it does not mean that Xin equals Li. The relations between Xin and the remaining four viscera are similar to the relations between RenXin(人心) and DaeXin(道心) and Zhuzi's(朱子) theory in many respects. If the theory that Xin equals Daoxan and FeiPiGanShen(肺脾肝腎) equals RenXin is acceptable, the vertical relations between Xin and FeiPiGanShen can be explained. That is, Xin is explained as the controller of the body, and FeiPiGanShen acts as a subordinate serving Xin. In other words, the relations associated with Xin can explain physiological states of the body. When the Xin does not function normally, FeiPiGanShen cannot perform its roles and will have a negative impact on physiological functions of the body.

The main purpose of this study was to develop a novel, in situ gel system for sustained delivery of ranitidine hydrochloride. Ranitidine in situ gels at 0.2%, 0.5%, and 1.0% gellan gum concentration (w/v) were prepared, respectively, and characterized in terms of preparation, viscosity and in vitro release. The viscosity of the gellan gum formulations in solution increased with increasing concentrations of gellan gum. In vitro study showed that the release of ranitidine from these gels was characterized by an initial phase of high release (burst effect) and translated to the second phase of moderate release. Single photon emission computing tomography technique was used to evaluate the stomach residence time of gel containing $^{99m}Tc$ tracer. The animal experiment suggested in situ gel had feasibility of forming gels in stomach and sustained the ranitidine release from the gels over the period of at least 8 h. In conclusion, the in situ gel system is a promising approach for the oral delivery of ranitidine for the therapeutic effects improvement.

Background: There are concerns about the health effects of various environmental pollution exposures among residents living near coal-fired power plants (CFPP). Objectives: This study attempted to compare the concentrations of heavy metals in blood and urine and those of urinary volatile organic compound (VOC) metabolites according to the residential separation distance. Methods: Participants in the study totaled 334 people who have lived for more than 10 years in areas within 10 km of a CFPP. The separation distance was analyzed in quartiles by dividing it into Q1 (88 people), Q2 (89 people), Q3 (89 people), and Q4 (68 people). We explained the purpose of this study to the participants and collected blood and urine after obtaining signatures on a participation agreement. Results: The study participants were 102 males (30.5%) and 232 females (69.5%), with an average age of 71. The average length of residence and distance were 43.8 years and 4,800 meters. The geometric mean concentrations of Pb, Cd, and Hg in blood and As and Cd in urine were respective 1.35 ㎍/dL, 1.43 ㎍/L, 3.16 ㎍/L. They were 167.88 ㎍/g for creatinine and 1.58 ㎍/g creatinine. The metabolite concentrations of VOCs were 50.67 ㎍/g creatinine in t, t-muconic acid (t, t-MA), 10.73 ㎍/g creatinine in benzyl mercapturic acid, 317.05 ㎍/g creatinine in phenylglyoxylic acid, 123.55 ㎍/g creatinine in methylhippuric acid, and 190.82 ㎍/g creatinine in mandelic acid. The concentration of Pb in the blood and Cd and t, t-MA in the urine of residents within affected area of the CFPP showed statistically significant differences among distance groups. Conclusions: The concentration of urinary VOCs metabolites, especially t, t-MA, differed according to the distance groups of residents within the affected area of CFPP (p<0.05).

This study was conducted to investigate the nutrient distribution and controlling factors in small stream estuaries. The seasonal variations of nutrient concentration (nitrate, ammonium and phosphate) were observed from 2010 to 2012 in the three streams located in Dang-hang (closed estuary: Go-seong, open estuary: Gu-man and Ma-am). The nutrient concentrations in Go-seong were significantly higher than other estuaries, because Go-seong is relatively large and has large nutrient load from the watershed. The dyke located at the estuary, also, caused the high nutrient concentration by reducing the dilution and increasing residence time. In all three streams, nitrate concentration was high at upstream and decreased toward the downstream, because high load of nutrient input were located at upstream. Dilution and biogeochemical removal toward the downstream also caused the trends. Especially, denitrification, a typical nitrogen removing process showed clear tendency of gradual decreasing from upstream to downstream. However, Ammonium and phosphate concentrations were high at upstream and decreased toward the downstream only when the nutrient loads from the rivers were high. Nutrient concentrations were low in summer and high in winter. Freshwater discharge in summer caused a decrease of the residence time and increase of the transport of nutrients to downstream and reduced the nutrient concentrations in the estuary. Nutrient removal by the biological production during high temperature periods also affected the low nutrient concentrations. Small stream estuaries showed distinct nutrient dynamics. It is necessary to understand these characteristics in order to properly manage the small stream estuary.

Previous studies on the factors affecting residents' migration have shown that residents who feel dissatisfied with their residential environment are more likely to move to another area than those who feel satisfied. The main purpose of this study is to investigate the subjective evaluation of the decline of the place and its impact on the intention to stay. This study used the data from Hankyoreh 21 survey of the residents who have been residing in the declining regions. The main finding of this study is that residents have a much higher propensity to stay as they become older. The fact that residents' staying intention tends to increase with age seems to be closely related to physical and economic constraints of older residents. Therefore, it can be inferred from the result that the elderly are more likely to be exposed to disadvantageous environments than the young residents in the declining regions.
