The purpose of this study is to analyze the characteristics of a life cycle of a theme park through looking at Everland in Yongin, Korea. The life cycle of Everland is divided into four stages. In "initial development" stage(1976 - the mid-80's), Everland become inclined the characteristics of an amusement park by constructing the amusement facilities in the Flower Center(botanical garden). In "growth" stage(the mid-80's - the early 90's), Everland had full grown to the amusement park and inclined to a theme park. In "maturity" stage(the early 90's - the mid-90's), many visitors were not motivated to re-visit Everland because the facilities and events did not change often. Therefore, Everland makes plans for multiple theme park. In "rejuvenation" stage(after the mid-90's), Everland has practiced the plans for multiple theme park and has become the family and accommodating-oriented theme resort park. Since 1976 when Everland was opened, it has evolved from an amusement park to a theme park by creating various and continuous innovations in facilities and events.

Objectives : The inclusion of Korean Medicine in the national health care system led to the need of a serious discussion on its modernization. This paper looked at how these discussions were progressed. Especially, a difference in the meaning of 'science' in the 1950s and the 1990s was observed. Methods : Articles related to the medical dispute between Korean and Western Medicine in "EE LIM", especially the ones from the 1950s, were selected, classified and analyzed. Research papers on Evidence-Based Medicine were also analyzed. Evidence-Based Medicine was a new medical research methodology in the 1990s. Articles on Evidence-Based Medicine were searched and selected from journal databases: DBpia, KISS, RISS, and OASIS. Results : The problem of establishment of modernity of Korean Medicine in the recent times was addressed in the context of scientification and systematization. Accordingly, the academic societies of Korean Medicine aimed for scientification. But efforts to secure the identity of Korean Medicine opposed to western science were also made. Meanwhile, Evidence-Based Medicine established in 1992 presented a different concept of science. This led to a new means of acknowledgement of Korean Medicine in the modern society. Conclusions : The modernization process of Korean Medicine up to now was a course of scientification. But as this process did not fully reflect its characteristics, the modernization of Korean Medicine still remains a pending question. A modern study methodology that fully reflects the identity of Korean Medicine needs to be established.

Popular music is a spce where intrinsic desires and values of young people are well exposed in its process of production and consumption. Previous discussions of Korean youth and youth culture have been proceeding mainly in the sense of their resistances to older generation. However, this is limited in that it neglects the inherent microscopic characteristics of youth culture. The purpose of this study is to investigate what the signs and discourses of youth generation make and share in popular music, and how it relates to social context through the 'Mimesis' theory. As a result, the songs of the 1990s remarkably showed the resistance to the old generation in its narrative structure and have signs which expresses repression and uniformity. On the other hand, the songs of the 2010s have many fragmented signs which has been reconstructed into individualized discourse structure. It is assumed that the songs have been able to gain a lot of empathy and popularity from the young generation by visualizing emotions and desires experienced by themselves in the social context. Through this study, it suggests to pay attention to the sensitivity, desire and creativity of young people in music in the social and cultural context of the time.

This study first analyzes economical environment change (factor) of investment nation Japan and Japanese enterprise at the analysis of Japanese enterprise's over-seas expansion factor and influence. As a result of an analysis of the factor about Japanese enterprise's overseas expansion from 1990 to 1996 and from 1998 to 2006, commonly applied factors were Yen exchange rate, interest rates, wage, enterprise profit, facility investment, and consumption expenditure. Especially, as a result of regression analysis, a sudden change of "low interest rate" was main factor at Japanese enterprise's overseas expansion from 1990 to 1996, and Japan's "Yen ex-change rate" was drawn as an important factor from 1998 to 2006. That is, from 1990 to 1996, a shock by a sudden rise in Yen value could be viewed gradually accumulated and absorbed inside Japanese economy from 1998 to 2006. Whereas it could be said that Japanese enterprise's overseas expansion was accelerated under Japanese government's overseas supporting policy and "low interest rate" together with the factor in the rise of Yen value from 1998 to 2006.

Zooplankton were sampled horizontally with a standard net from the surface layer of the estuarine system of Mankyong River and Dongjin River in October, 1989, March, May, and July, 1990. Among dominant taxa of the zooplankton community, copepods were predominant in October, 1989 and March, 1990 and Noctiluca scintillans in May and July, 1990. Abundance of zooplankton showed considerable spatial and temporal fluctuations with a range of $12~9,256ind./m^3$ in wet weight. In the copepod community, Pseudodiaptomus inopinus and Paracalanus inducus were predominant in October, 1989: Acartia hudosonica and P. inducus in March, 1990; A. hudosonica and Centropages abdoinalis in May, 1990; A. pacifica, P. indicus and Tortanus spinicaudatus in July. 1990. In summer (July),there were large seasonal changes in salinity ($0.7~28.9\textperthousand$), due to monsoonal flooding, and associated changes in community structured of copepods. There were eight species of copepods in the mixo-mesohaline zone ($5.0~28.8\textperthousand$), namely Acartia pacifica, A. hudosonica, Centropages tenuiremis, C. abdominalis, Labidocera Euchaeta, Tortanus spinicaudatus, corycaeus affinis and Paracalanus indicus. On the other hand, Thermocouple hyalinus, Pseudodiaptomus inopinus and Sinocalanus tenellus occurred in the mixo-oligohaline zone ($0.5~5.0\textperthousand$), showing more tolerant of low salinity than any of the other species. In the mixoeuhaline zone ($>28.0\textperthousand$), Labidocera bipinnata, Oithona similes, Calanus sinicus, Acartia omorii and Tortanus forcipatus were founded.

Mackerel is one of the most widely consumed aquatic products in Korea. Concerns about the depletion of stocks have also arisen as the catch has decreased. The primary purpose of this study is to estimate the mackerel stock and derive the optimal level of catch in Korea. We apply a generalized maximum entropy econometric method to estimate the mackerel growth function, which does not require the steady state assumption. We incorporate a bootstrapping approach to derive the significance levels of parameter estimates. We found that the average ratio of catch to the estimated total stock was less than 30% before the 1990s but exceeded 40% in the 1990s. After 2000, it dropped back to about 36%. This finding indicates that mackerel may have been over-fished in the 1990s, but the government regulations introduced in the 2000s alleviated over-fishing problems. Nevertheless, our dynamic optimization analysis suggests that the total allowable catch may need to be carefully controlled to achieve socially optimal management of resources.

Objectives : Based on data collected from patients who suffered from dental caries during the period between 1990 and 2008, the number of patients and their trends were analyzed as a source of evidence to conduct the oral health plan. Methods : A population of sample design for patient survey data was derived from computerized data saved at medical institutions accredited by National Health Insurance Corporation. Large institutions such as dental hospitals were included for the complete enumeration test, while the rest of medical institutions, for example, dental clinic, relatively small institutions, were used for the sample survey. Most of patients with dental caries were outpatients and their disease was treated at the dental hospital or dental clinic in general, therefore, main analysis was carried out at those institutions. Results : The rate of patients who suffered the dental caries has decreased to 56.8% in 2008 from 78.5% in 1990. The rate of patients who visited the dental hospital for treatment has increased to 4.8% in 2008 from 0.5% in 1990, whereas the percentage of those who visited the dental clinic has fallen to 97.9% from 99.5% during the same period. The ratio by age, in the meantime, it showed that patients aged 40s has increased to 13.5% in 2008 from 7.2% in 1990, and the number also has risen in 50s from 5.6% in 1990 to 9.9% in 2008. However, the number of children aged 0 to 9 who visited hospital for treatment of dental caries has fallen to 17.0% in 2008 from 33.9% in 1990. Conclusions : By figuring out the trends of patients with the dental caries during the period between 1990 and 2008, fundamental data for the oral health policy have been collected. As a result, the necessity of a new medical treatment system for managing the dental caries in terms of patient ages as well as the oral health policy and campaign was taken into consideration.

North Korea has been in ecologically deficit state since 1966, despite of lack of energy and food resources. Trends of the Biocapacity (BC), the Ecological Footprint (EF), and the Ecological Deficit (ED) of North Korea were shown and five factors influencing on the Overshoot Rate (OSR) which is the ratio of the BC and the EF in North Korea was analyzed in this study. The five factors consist of two factors affecting to the EF and three factors affecting to the BC in North Korea. Two of the five factors are affecting to the EF those are population, the EF per capita (EFPC) which indicates the individual environmental consumption intensity, and three are affecting to the BC those are the land area, the yield factor, and the value multiplying the equivalence factor and the intertemporal yield factor. The EF has contributed more than the BC to the OSR. From 1966 to mid-1990s, the EFPC was the most contributing factor at about 60%, and after mid-1990s, population at about 40~60%. Contribution ratio of land area and the yield factor have increased after mid-1990s up to 15% and 18%, respectively. The BC of cropland which has decreased due to a decrease in productivity. In order to reduce the ED of North Korea, improvement of productivity of cropland and restoration of forest. Forest area has decreased significantly since 1990 in NK. And ways to solve the food shortage problem which influences on decrease of both productivity of cropland and forest area.
