This study tried to develop a model which can predict a long-term of forest recreation quantity corresponded with econometrics. Simultaneously this study was conducted with the aim of development of practical matrix which is able to apply forest recreation management with policy-control variables about forest supplement with some problem of former study using only a cross-section analysis. As the results of analyses, forest recreation quantity is affected (-) relation by distance, (+) relation by population of the origin area, the size of forest, and a destination's annual social expenditure. In addition, the distance variable is elastic, however, the other variables are inelastic. This results might correspond to a general gravity model theory about forest recreation quantity.

The purpose of this study is to make practical application of the results as basic data of National Park management-policy by surveying and analyzing management goals, management missions, land zoning, numeral of visitors, management organization, management staff and revenue and Expenditure budget of 1992 and 2004 those are main factors to know the management system well. The main management missions was found not only to put value on developing nature program but also to prepare for keeping and renewing of nature resources. The change of zoning land was researched to be controlled and nature preservation area was showed to be enlarged. While management missions and visitors have been increased, there weren't raise of organization and staffs at all. And expenditure budget had management formation by manpower. Although there are progressive changes in park management system during the period, several improvements are needed in details. They are as follows; To be sustainable preservation and usage which are the intrinsic roles of National Park by increasing the government investment than own revenue.

This paper analyses the relationship between regional economic power defined as GRDP per capita and various socioeconomic variables such as fiscal variables(revenue, expenditure, etc.) as well as nonfiscal variables(population, ratio of old population, unemployment rate, dependency ration) using the pooling data of 16 local governments from 1998 to 2012. To put it concretely, following the Granger causality test, regression analysis has been done with the regional economic power being the dependent and variables which have either one or two direction causality being independent variables. And test of cumulative effects has been done with variables showing statistical significance in the regression analysis. Local tax revenues per capita, expenditures of social development per capita and median age have positive effects, while dependency ratio has negative effect on regional economy. And national subsidy per capita, local tax revenues per capita, expenditures of social development per capita and median age all have cumulative effects on regional economy.

Objectives: The purpose of the study was to classify the health and medical service affairs of local governments, and to analyze the proportions of non-matching fund by local governments and central government subsidies for local government health budget. Methods: First of all, health affairs of local governments were classified to categories based on health-related laws and previous studies by review of the authors. In order to specify the scale of local government-led health affairs, we allocated 1,916 budget units into 6 main and 24 sub categories of the health and medical service affairs of local governments for the 2020 health budget of Jeju Special Self-Governing Province. For each categories, we compared the total amounts and the percentages of the 'central government subsidies', 'local government budget - matching fund', and 'local government budget - non-matching fund'. Results: The total health budget of Jeju Special Self-Governing Province accounts for 1.2% of the total budget. Of the total health budget of Jeju Special Self-Governing Province, the proportion of central government subsidies was 39.6% and the proportions of local government budget-matching fund and non-matching fund were 33.8% and 26.6%, respectively. The proportions of non-matching fund by provincial and basic local governments were 37.3% and 19.9%, respectively. Conclusion: In order for local governments to deal with the health problems of residents, it is necessary to secure and spend more local government budget(i.e., non-matching fund by local government) for health affairs in their administrative jurisdiction.

Reduction smelting of spent lithium-ion batteries at high temperature produces metallic alloys. Following solvent extraction of the leaching solutions of these metallic alloys with either sulfuric or hydrochloric acid, the raffinate is found to contain Ni(II), Co(II), Mn(II), and Si(IV). In this study, two cationic exchange resins (Diphonix and P204) were employed to investigate the loading behavior of these ions from synthetic sulfate and chloride solutions. Experimental results showed that Ni(II), Co(II), and Mn(II) could be selectively loaded onto the Diphonix resin from a sulfate solution of pH 3.0. With a chloride solution of pH 6.0, Mn(II) was selectively loaded onto the P204 resin, leaving Ni(II) and Si(IV) in the effluent. Elution experiments with H₂SO₄ and/or HCl resulted in the complete recovery of metal ions from the loaded resin.

A method for separating heme-iron from hemoglobin (Hgb) hydrolysate by dialysis was developed. Recovery of heme-iron increased with increasing Hgb concentration, whereas rejection of peptide and separation effciency expressed by HP ratio (heme-iron/peptide) did not show significant differences. HP ratio increased with increases in the degree of hydrolysis of Hgb and $KH_2PO_4$ concentrations of dialysis solution. Recovery of heme-iron decreased with increase in the pH of dialysis solution due to wash-out of heme-iron across the dialysis membrane caused by increase in solubility of heme-iron. Rejections of peptide were 74.5 and 87.5% (2 and 5 kDa of cut off size, respectively), whereas recovery of heme-iron decreased from 86.5 (2 kDa) to 63.1% (25 kDa). Amounts of heme-iron and peptide of dried heme-iron product were 21.7 and 77.0%, and HP ratio and production yield were 28.2 and 6.5%, respectively.

To evaluate the effectiveness of GnRH agonist for the treatment of uterine myoma as a cause of infertility, fourteen women were recruited to the study. The patients were treated with a delayed-release formulation of D-$Trp^6$-LHRH in biodegradable microcapsules(Decapeptyl-CR), administered intramuscularly at four week intervals for a period of six monthes. The first injection was given on day 21 of the cycle. Serum estradiol levels fell significantly to the mean value of 257.7pgjml 4 weeks after the first injection. Eleven patients in fourteen treated patients had a reduction in the size of uterine myoma as assessed by ultrasonography, two patients had no change of size and one patient had a increase of size. After the first or second injection, all patients became amenorrheic, then resumption of menstruation ocurred at 12 to 14 weeks after the last injection. Common side effects were hot flush, sweating and dyspareunia, whitch were acceptale. In Eleven patients who had a reduction in the size of uterine myoma by treatment with a delayed- release formulation of D-$Trp^6$-LHRH(Decapeptyl-CR), after above treatment with GnRH agonist, then four patients were treated with myomectomy, three patients had pregnancy and full term delivered by Cesarean section. These data suggest that administration of a delayed-release formulation of a GnRH agonist can be a worthwhile and convenient approach to the medical treatment of uterine myoma as a cause of infertility.

As an exploratory research to understand the nature of relationships between ports and their neighboring communities, this study analyzes how ports influence their residents' quality of life(QOL). The QOL was measured by 17 indicators reconstructed by reviewing relevant literatures. As a result, both Busan port and Dalian port were found to have statistically significant influence on many of QOL indicators including general expenditure per capita, number of manufacturing factories per capita, number of factories's laborer per capita, the rate of pavement, number of traffic accident per capita, rate of housing supply, number of financial agencies per capita, park area per capita, number of cultural assets per capita, the size of welfare expenditure per capita, number of fire occurrence per capita. And Busan port have statistically significant influence on QOL indicators including the rate of increase in population, number of public health industries per capita, number of public health industries per capita, number of schools per capita, number of sick-beds per capita, but Dalian port not have influence. Also Dalian port have statistically significant influence on number of crime occurrence per capita, but Busan port not have influence.

Social overhead capital(SOC) is an essential element for society to be developed and operated normally. In spite of the increase in the importance of SOC, It is difficult to present the criteria for the appropriate investment of SOC. and The discussion on making SOC investments of local government is insufficient. If the local autonomy has been guaranteed, local government increases investment in regional public goods that residents prefer. Reflection of such residents preferences is the driving force to bring the efficiency of resource allocation in the decentralization theorem. In this study, the authority and autonomy of local governments are measured through local finance. and the decision-making of local governments for SOC investment is examined in point of decentralization theorem. In the empirical analysis, the elasticities of fiscal resources are estimated for facilities(road, water and sewage, irrigation canal and flood control) that local governments are involved in investment. These decisions made by metropolitan cities and provinces were different. The difference was most evident in the effect of per capita local tax on investment. These results show that metropolitan cities and provinces that have different situation made investment decisions differently. It shows that local governments reflect the preferences of the residents in making an investment. The main implication of this study is as follow. In case the role of local government in social overhead capital investment is increased, the increase in efficiency of resource allocation occurs. and The fiscal resources must be raised by local taxes rather than the financial resources from the central government.

Recently according to increasement of the single family and dual-earner couples, the number of infants and young children stays on a long time to the childcare facilities. this is increasing the importance to improve the physical environment. However, the operating and maintenance costs of the national-public childcare facilities have taken effect of the unfair support issues of municipality's financial situation. Especially, because of the lack of the operating and maintenance costs of the facility and the shortage of facilities equipment maintenance repair costs, nursery operations and Maintenance items are needed to distribute appropriately. Therefore, this study is to estimate the importance to facility operations and maintenance items based on "Kindergarten and Childcare Facilities"presented at the Child Care Policy Study. we are expected to allocate appropriately of operation and maintenance cost of a limited budget. In particular, those can be considered for operation and maintenance cost about the National-Public Childcare Facilities and be determined to a safe and pleasant environment to kindergartens through the appropriate operations and maintenance support.
