Serious games are developed under particular purpose. This study provides a theoretical background on serious games for social change as a basis for future experiments and practice. By examining the elements of games and related theories, narrative immersion and critical participation are identified as the two main experiences of games, which are realized through role play. Based on educational theories for behavioral and cognitive change, this study suggests to use role play as a strategy on serious games for social change. Analyzing the cases of serious games in Korea, this study concludes that participants are able to experience the context of the situation through role play.
It is only possible by Physical based Water Balance Models such as $BROOK_{TOP}$ developed by me to estimate regional water balances caused by changes of regional ecosystem, which result in climate change, change of vegetation due to climate change, artificial landuse change, etc. This study estimates regional water balances of mid-north agricultural and forest regions in Germany using $BROOK_{TOP}$-Water Balance Model with climate change scenarios developed by PIK in Germany and GCM Scenarios developed by Praha University in Czech. Developing Water Resource Change Estimation System such as this study for global warming with considering climate, surface and underground conditions provides the basis of system development for surface-, groundwater-, cultivation-, ecosystem-, natural emergency-management, landuse and regional planing.
The conception of 'earth(土)' belonging to the five evolutive phases(五行) is cognized that it is not partial to any side differing from other four phases and it can control other four phases so, it is the first gate to enter the process of changes. In the five organs(五臟), the spleen come under the earth phases and it have been very importantly considered for past to now in oriental medical history, for example by Li Dongyuan(李東垣). In this study, the results are summarized as the followings. 1. The term of the acquired constitution(後天) made by So-ong(邵雍), a scholar in the north so-dynasty, is used in the study of the book of changes(易經). And he said "The inborn constitution(先天) is the law of the nature itself and, the acquired constitution(後天) is the law of making the changes with the nature." In the myung-dynasty Li jungjae(李仲梓) made extract from this remarks 10 define that the spleen is the basis of the acquired constitution. So it considered that the the idea of changes(易) had an effect on the oriental medicine. 2. The one element of five phases, earth is the center of the changes and it composes the power of life with the sangsu(生數)-1, 2, 3, 4, and the sungsu(成數)-6, 7, 8, 9. In this process, the earth is the basis of the changes of the five phases. At the same time the spleen carry out the important physiological role in the humanbody controlling the other four organs. 3. In the change of the universe, the repetitionary movement of Yin(陰) and yang(陽) is the action of earth and it means illimitable division. In the course of this division all things change to new phases for example, the food changes 10 the ki(氣) through the action of spleen and stomach. So the organ of spleen and stomach is the space that the action of change occur. 4. Consequently the conception of bi(脾) is close to the pancreas that the spleen. And the duodenum is close to the conception of stomach because the space is the site of mito(未土). 5. The action of yin and yang in the ancient taegukdo(太極圖) is close 10 the connection of N-pole and S-pole. In the humanbody the two power is compared to the action of spleen and kidney, that means expansion and contraction. Also it means the inborn constitution and the acquired constitution so, it applyed to the all things in the universe.
This study was undertaken with the aim to establish a reliable radioimmunoassay (RIA) system for urinary pregnanediol glucuronide (PdG) and to employ it for monitoring the reproductive status of dairy cows. Urine and blood samples were collected from the Holstein cows both pregnant and non-pregnant. The samples were then investigated for evaluating the relationship between progesterone ($P_{4}$) in blood and PdG in urine adjusted with or without urinary creatinine basis. Biweekly urine collection was employed for three cows in estrous and those artificially inseminated, while urine from pregnant cows was collected on a monthly basis. P_{4}$ and PdG levels were measured by enzymeimmunoassay (EIA) and RIA techniques, respectively. Our results indicated the sensitivity of PdG for RIA being 35 pg/tube and the recovery rate of 100%. Urinary creatinine concentrations also fluctuated within a day, but change at midday was not noteworthy. Regardless of the time of urination the change in concentrations of PdG was relatively smaller and did not vary significantly. The urinary PdG concentration showed periodic changes as that with serum P_{4}$ levels during the cow's estrus cycle. The correlation coefficient rose when creatinine level in urine was adjusted but the change was also not significant. The concentrations of PdG during the luteal phase were detected between 8.2 and 17.4 ng/ml, three to five times higher than that in the follicular phase. The concentration of PdG from pregnant cows (21 days after conception) was three to four times higher than in the nonpregnant cows. Our finding suggests that the determination of urinary PdG could be reliably employed for early pregnancy detection. The urinary PdG level continued to raise until 30 days pre-partum while the concentration reached its peak at 30 ng/ml, after which it started to fall 18 to 30 days before parturition and finally fell to its nadir value one week after parturition. As the correlation coefficient between the urinary PdG and serum P_{4}$ was higher than that corrected by urinary creatinine it can be suggested that the adjustment is not needed. The concentrations of urinary PdG could be maintained stably for 2 days in urine samples stored at room temperature and extended to 8 days when the samples were pretreated by boiling for 30 minutes. In conclusion urinary PdG concentration even without the need for creatinine basis adjustment can be used directly for monitoring the reproductive status of dairy cows.

This paper tried a detailed approach to identify the correlation among basic elements that influenced the change of forms of the Po. To this end, the subjects were limited to the clothing from the 15th to the 18th century, which was found in the tombs of the period of Pyeonbokpo. The total number of excavated artifacts measured directly is 6 and other correctly described excavated artifacts for a total of 54 items. Per period and element, the types of collars and Seop were presented by classifying collars in 4 types, and Seop in 3 types. On the basis of the classification, the relics selected in this paper were analyzed considering the appearance, period, and rate per type of each element. The type and the change of forms of each element per period, with the focus on the appearance, were identified and the factors influencing the change of forms per element and the correlation between such factors were investigated. The representative type in the first period included dual collars, dual Seop and the representative type in the second period was characterized by a shawl collar and a dual Seop joining the pieces. The representative type in the third period was characterized by round collars and a short Seop. The elements determining the forms of Po, including collars and Seop, had a correlation to the lapse of time and had been systematically influencing each other. Furthermore, the overall change of form was caused due to the social functions as well as the supplementary function of keeping balance among the elements and accordingly, the change of forms was think characterized per period.
Purpose. The purpose of this study was to test the effectiveness of a comprehensive smoking cessation program for Korean adolescents. Method. The study design was quasi-experimental with one pre and three post-tests. The three posttests were done immediately after, three months later, and six months after the completion of the program. A total of 43 high school students who smoked participated in the study with 22 in the experimental group and 21 in the control group. The smoking cessation program consisted of 9 sessions with content on enhancement of self-efficacy, stress management, correction of distorted thoughts, consciousness raising, and assertiveness training. The study variables were urine cotinine levels, self-efficacy, stress, and stages of changed behavior. Results. Urine cotinine levels significantly decreased in the experimental group after the program (F=3.02, p=.06) but significantly increased in the control group (F=6.32, p=.004). Self-efficacy and the degree of stress did not change in either group. The stages of smoking cessation behavior tended to change when compared with raw data for the experimental group. For most participants, the stages of change had been precontemplation and contemplation, but changed to action and maintenance stage among the experimental group. Conclusion. The program was effective in smoking cessation and influencing stages of change but did not change psychosocial factors such as self-efficacy and stress. It is suggested a program should be developed to change psychosocial variables on a long-term basis. It is also desirable to involve peers and families of adolescents who smoke when planning programs to enhance social support.

The monthly mean air temperature datasets of 61 stations in South Korea from 1973 to 2012 were collected to calculate trends in the warmth index (WI) and to analyze the potential enlargement of safety cultivation limit for sweet persimmon. The WI averaged over the last 40 years was 104.1 (℃·Month) at 61 stations, with the highest at Seogwipo station (WI=137.9) and the lowest at Daegwallyeong station (WI=60.9). It has increased by 1.8 (℃·Month) per 10 years over the last 40 years, with the highest in the year 1994 (WI=112.0) and the lowest in the year 1976 (WI=94.7). When the possible stations for sweet persimmon cultivation were classified by the basis on WI≥100, 38 out of the 61 weather stations were included in the safety cultivation zone for sweet persimmon for the last 40 years. On the other hand, the number of weather stations within the safety cultivation zones for sweet persimmon for the last 10 years (from 2003 to 2012) were 47 by adding additional 9 stations (Socho, Wonju, Chungju, Seosan, Uljin, Yangpyeong, Icheon, Cheonan, and Geochang stations). A further study of the climate conditions and soil characteristics is required for a better assessment of the safety cultivation zones for sweet persimmon.
Purpose: The study was performed to identify the process of change, decisional balance and self-efficacy corresponding to the stage of exercise behavior change based on a Transtheoretical Model in middle aged women. Method: The subjects consisted of 317 women by convenience sampling residing in city B. The collected data were analyzed using one-way ANOVA, Scheffe test, and Discriminant analysis by SPSS/WIN program. Result: The subjects were distributed in each stage of change of exercise behaviors: 53 subjects (16.7%) in the precontemplation stage, 86 subjects (27.1%) in the contemplation stage, 88 subjects (27.8%) in the preparation stage, 51 subjects (16.1%) in the action stage and 39 subjects(12.3%) in the maintenance stage. Analysis of variance showed that consciousness raising (F=24.96, p=.00), environmental reevaluation (F=7.l3, p=.00), self reevaluation (F=19.47, p=.00), dramatic relief (F=15.22, p=.00), social liberation (F=4.26, p=.00), counter conditioning (F=26.44, p=.00), a helping relationship (F=13.l7, p=.00), reinforcement management (F=21.25, p=.00), self liberation (F=27.70, p=.00), stimulus control (F=13.49, p=.00), pros (F=14.40, p=.00) and self-efficacy (F=39.9l, p=.00) were significantly associated with the stages of change of exercise behaviors. Through discriminant analysis, it was found that ‘stimulus control’ was the most influential variable in discriminating the five stages of change. Conclusion: This study can provide the basis of a staged matching exercise program using TTM for more effective and useful intervention.
Recently, Seoul residential real estate market showed a big change, especially in 2007. The residential property price in Seoul had been mainly affected by 5 provideces: Kangnam-gu, Seocho-gu, Songpa-gu, Gangdong-gu and Yangchun-gu, but these providences started to show the decrease in price while the other providences ironically showed the opposite direction. Therefore, this project was derived from this phenomenon recognition and the necessity as the new market trend requires. The pre-research was carried out with the point of social-population academic view, but this project provides the analysis on the new market trend by simplifying the complex valuation indexes, originated from the pre-research. In result, the aspects of the change could be categorized into time-manner classification and territorial-manner classification, in cope with the change in the satisfaction degree on the residential environment and the selection tendency of the residential property. Based on the the moving-preferred area criteria, the territorial classification was categorized into 3 areas: 5 providences, which showed the initial decrease in real estate price (area 1), the other Kangnam area (area 2), and Kangbuk area (area 3). The result illustrated the reasonable change in the satisfaction degree on the residential environment and the selection tendency of the residential property. This project was able to reach the following conclusion : Firstly, the housing development planning should be devised by the residential environment, including the view and the natural environment, not by the area. Secondly, the housing development planning in the other Kangnam area (area 2) and Kangbuk area (area 3) should embrace the business function, not the housing development only. Last, the housing development planning in Kangbuk area (area 3) should be able to enhance education and culture function and be connected by various transportation system. This project analyzes the change in the satisfaction degree on the residential environment and the selection tendency of the residential property. Thereafter, this project has the purpose of providing the aid in understanding of the basis of housing development information.
Resistivity changes of n-type float-zone silicon crystals with 6.4$\times$10$^{14}$ to 1.25$\times$10$^{17}$ phosphorus atoms/㎤ due to irradiation by (1) 1 MeV electrons, (2) two types of research reactors, and (3) $Co^{60}$${\gamma}$-ray sources were investigated. The results were analyzed on the basis of a simple exponential formula derived by Buehler. While the formula gave a fair fit in the low fluence range in most cases, the deviation was quite appreciable in the case of 1 MeV electron irradiation, and a linear change gave better fit in some cases. The large change in the carrier removal rate in electron-irradiated samples in the high fluence range was analyzed in detail in terms of the Fermi level cross-over of the defect levels. Based on the damage constants evaluated from the initial portion of data where the formula was applicable, the relative effectiveness of various radiation sources in causing the resistivity change in n-type silicon was compared. The TRIGA Mark II reactor neutrons, for example, were found to be about 40 times more effective than 1 MeV electrons. The dependence of the damage constant on the initial carrier concentration was also examined. The physical basis of the exponential law and the effect of the Fermi level cross-over of the defect levels on the resistivity change in the high fluence ranges are discussed.
