This study was conducted to grasp the present condition of the name and the related text of the domestic laws (97 statutes, 1 examination, 1 guide, 3 ordinances, 1 leading case) in force which were connected with landscape plant and planting. Examining the general tree-planting system of America, the related foreign laws(1 constitution, 44 statutes, 31 ordinances, 6 leading cases) were arranged in the name and the text and classified by nations of regional groups and it was considered to the mutual relation with lots of laws which are scattered with the various laws. To examine the points at issue of the related domestic laws and to study the related foreign laws, the remedies for the domestic laws being at issue were proposed. That is : A change of the landscape planting concept, the introduction of the landscape planting cost compared with the total construction cost, the unification of the landscape planting ordinances as the unit of city, the clarification of the completion period for the depect of the replaced trees. putting the conservation and production of the top soil under an obligation the adoption of a licence system for the tree planting within the river area, the introduction of the allotment system for landscape architectural expenses, the encouragement of making a hedge, the settlement for the problems of the trees loss compensation, the necessity for the quality test to the landscape planting works, the intensification of the punitive rules to the illegal felling and planting of the trees in the greenzone area, the application of the Labor Standard Act to the landscape planting laborers. The laws relating to landscape plant and planting are prescribed dispersedly in the many other related laws and it is concluded to be impossible for the legislation of the singular law which is applied uniformly to the department of the tree-planting. Hereafter it should be required to analyze concretely in detail the each text of the related laws by means of the joint studies between the professional landscape architects and the lawyers.

The expenses of maintenance and reinforcement for aged concrete structures are significantly on the increase as their durability and general performance has been naturally degraded. Due to this reason, interests on concrete crack reduction technology are growing but more researches are required to fulfill such fast growing demands. Particularly in the underground power facilities, it is difficult to maintain the quality of aging concrete spheres for underground power as their deterioration caused by long-term operation is on-going. In recent years, many studies have been made to overcome the issues and now it is determined that the shrinkage reducing technology which can dramatically reduce the crack at the design stage is one of the most effective solutions. In this study, the test investigated fundamental propertiesof concrete using various shrinkage reducing materials to develop low shrinkage mortar. According to results of experimental study, for mortar and concrete, glycol based material showed excellent shrinkage property and compressive strength. For the later study to generic application of the shrinkage reducing materials, performance reviews on the shrinkage reducing materials with variable factors and various materials such as changes in the amount and type of materials should be followed.

The profitability of a hospital refers to business administration results achieved through its medical care and other management activities during applicable fiscal year. This study focused on operating margin as a measurement index of hospital profitability, which is a genuine medical return obtained by subtracting medical expenses from medical profits achieved during business administration of hospital. Based on the index, this study could deduce certain factors on hospital profitability in terms of various indices affecting profitability. And based on those factors, this study sought to provide more useful reference materials which allow us to devise possible ways to improve hospital profitability. As a result, it was found that public hospitals attained lower profitability than private ones. To analyze profitability depending on each index, this study divided hospitals broadly into deficit group and surplus group. As a result, it was found that there were significant differences in hospital profitability between two groups depending upon relevant indices such as labor cost ratio, maintenance expense ratio, number of operations per medical specialist and medical instrument turnover. According to analysis on potential effects of relevant indices upon profitability, it was found that each index had its explanatory power ranging from 25% to 74.5% depending on given model.

The subjects used in this study were chosen from self-employed women in Taegu City, Korea, Data for 415 respondents were collected by face-to-face interviews conducted during the period of November 10 through 23, 1987. There are three major purposes in this study : first, to describe the general characteristics of self-employed Korean women's fertility behavior ; second, to examine the determinants of fertility behavior among self-employed women : third, to explore the relative importance of the fertility determinants among the women. Regression analyses were introduced to test hypotheses. Nine variables, such as household income, educational attainment, mass media, abortion, the period of contraception practice, contraceptive expenses, the number of infant, deaths marital period, and age at first marriage were introduced as indicators in the regression. The results of this study show that there are negative relationships between the dependent variable of fertility and abortion, and the period of contraception practice. On the other hand, positive relationships between the dependent variable of fertility and the number of infant deaths, and marital period and age at first marriage are shown in this study. However, the results of this study show that there are insignificant relationships between socioeconomic variables and fertility. From the results of the F test to evaluate the significance of difference in $R^2$between two different regression equations, we have found that the regression equation including both socioeconomic variables and intermediate variables is misspecified to examine the determinants of fertility behavior among self-employed Korean women. That is, the F test shows that the regression equation including only intermediate variables as indicators is the best model for this study. Finally, the relative importance of the fertility determinants among self-employed women is found as follows : Age at the first marriage is the most influential variable in the fertility, and the next important factors are abortion, the period of contraception practice, the number of infant deaths, and marital period, in that order.

As the super-aged society is imminent, the number of people with senile diseases is also increasing, resulting in a lack of facilities and policies as a social problem. National Health Insurance Service is being talked about as a realistic alternative to medical coverage. Long-term care hospitals are classified into acute-stage hospitals and long-term care facilities and are acting as an alternative to reducing medical expenses. However, in long-term care hospitals, which are the core of maintenance rehabilitation, the quality of service issues have been raised seriously. Currently, there is a problem of mass production of refugees from rehabilitation due to a problem of the medical system. In particular, in the preceding study in 2015, the status of long-term care hospitals in Jeollabuk-do was the worst. Therefore, using public data, the general status of long-term care hospitals in Jeollabuk-do, status of frequent disease, status of rehabilitation services, and status of occupational therapy services are to be explored.

The purpose of this research is to strengthen rural community empowerment by creating a tourism farm as a plan to reduce relative poverty and to improve the quality of life by creating jobs and increasing the income of local residents in underdeveloped countries. To do so, literature review, stakeholder interviews, on-site investigations, focus-group interviews, a project meeting for residents and a questionnaire survey were performed and analyzed and the results were as follows. First, Uganda has the potential to increase agricultural production based on its warm climate, fertile land and abundant natural resources. The quality of life of local residents is expected to be improved by realizing high-added values through the convergence of the conventional existing agricultural industry and other industries if the agricultural technology is properly transferred based on abundant labor force and low labor expenses. Opportunities for the success of the project can be spread to other rural villages across the country. Second, since local residents are now cultivating sugar cane, cassava, matoke, banana, coffee and so on as a farm owner, tourism agriculture with high-added values can be promoted by vitalizing communities based on farming technology to be transferred and a cooperative farm. It is also necessary to implement a rural community empowerment project to do so. Third, the university that is the cooperative partner of the project is positively considering to train experts by establishing a community development department, and, if necessary, a technical training center to educate the general public, which is expected to create synergic effects through the convergence of education, agriculture and tourism.

The purpose of this study was to identify the problems and improvement plans of grouphome management, by analyzing the sizes and items of children grouphome budgets of national and local governments. Major results of this study were as follows. First, the most crucial issue regarding labor costs within child grouphome budget, was that there was a significant difference in conditions between workers in similar institutions and regions. Small-sized institutions operated under a system that inevitably required excessive workload for workers, leading to exhaustion. Second, the support of operation expenses was absolutely insufficient to meet the general and special needs of children, and the relative differences between facilities of the same type were also identified. Third, children grouphome had limitations in stable business planing and implementation due to the absence of business expense support. Through this analysis, this paper discussed appropriate budget supporting measures regarding children grouphome, in order to ensure equal protection of grouphome children.

Purpose: We evaluated the status of patients enrolled in South Korea's pediatric palliative care pilot project based on the experience of a single center. This study examined factors related to end-of-life services and differences in medical costs. Methods: The medical records of 120 patients referred by a pediatric palliative care team were analyzed retrospectively. Data from July 1 to February 28, 2022 were collected and analyzed using the chi-square test and the Mann-Whitney U test. Results: Volunteer programs and psychological support (100%), family support and education (99.2%), and financial support through institutional linkage (62.5%) were provided to the participants. In the deceased group, there were no significant differences in general characteristics, which included age, gender, primary disease, religion, duration of hospitalization in an intensive care unit (ICU) and non-intensive care unit (non-ICU). However, the ICU group had fewer opportunities to access individual pain and physical symptom management than the non-ICU group and there were limitations in linking with external resources. Medical expenses were significantly different for the ICU group, with a 3-times higher average cost than the non-ICU group. Conclusion: Although an individualized approach is needed for each patient in pediatric palliative care, psychosocial care is essential. In addition, if early intervention for end-of-life pediatric patients is available from a palliative care team, the cost burden of medical care for patients and their families should be minimal.

Purposes: As super-aging population and low fertility rates are threatening the sustainability of the National Health Insurance funds, enhancing the efficiency of hospital management is paramount. In the past, studies analyzing the efficiencies of hospitals primarily made inter-hospital comparisons, but it is important to assess hospitals' internal efficiency and develop improvement measures in order to attain practical improvements in hospital efficiencies. The purpose of this study is to analyze the efficiencies of specialists by medical specialty in a hospital in order to provide foundational data for efficient hospital management. Methodology/Approach: We used the activity-based costing (ABC) data and hospital statistical data from one tertiary hospital in Seoul to analyze the efficiency of specialists by medical specialty. Efficiency was analyzed and compared among specialists using the data envelopment analysis developed by Charnes, Cooper, and Rhodes (DEA-CCR) model and the slacks-based measure (SBM) models. The input variables were labor cost, material cost, and operational expenses, and the output variables were the number of outpatients, number of inpatients, outpatient revenue, and inpatient revenue. Findings: First, there was a marked deviation in efficiency across specialists. Second, there was a marked deviation in efficiency across medical specialties. Third, there was little difference in efficiency according to the specialist's sex, age, and job position. Fourth, the SBM model produced more conservative results and better explained efficiency parameters than the CCR model. Practical Implications: The efficiency of a specialist was more influenced by their medical specialty than their personal characteristics, namely sex, age, and job position. Therefore, Further research is needed to analyze the efficiencies of each subspecialty and identify factors that contribute to the variations in efficiencies across medical specialties, such as clinical practices and fee structures.

Many researchers have analyzed the relationship between the financial success patterns of a motion picture and many other factors, such as the production cost, marketing, stars, awards, reviews, genre, and rating. Through these studies, many researchers and investors concluded that big budgets to make a blockbuster movie can serve as an insurance policy to meet their ROI; thus the box office is dominated by blockbuster movies. High-budget blockbuster movies are more likely to receive attention because these movies are more recognizable given their high expenses for production and casting. Therefore, audiences choose blockbusters in an effort to reduce the searching cost and to mitigate the possibility of a regrettable choice. This behavior of consumers, in turn, causes distributors to allocate screens for blockbusters, resulting in "concentration of blockbuster consumption." As such, low-budget films cannot easily become popular due to the lack of distribution. Indeed, low-budget films released on a small number of screens often end up becoming dismal failures. However, there are exceptional examples which are contrary to the general idea in the movie industry that a big budget and showings on a large number of screens can guarantee the success of a movie. Although researchers have attempted to analyze the performances of movies with small budgets, such movies are likely to be regarded as outliers and then be entirely discarded, as they are far from the 'three-sigma' range, especially given that previous research methodologies could not explain the financial success of such unique examples. This study attempts to explain the financial success at the box office of low-budget movies by applying the concept of the tunnel effect in quantum mechanics, as the phenomenon found in the movie industry is similar to a particle's movement in quantum physics. The tunneling effect is a phenomenon by which a particle without enough energy to pass over a potential barrier tunnels through it. Adopting the analogy, this study draws a tunneling probability function and cultural constant to forecast other outliers using the Schrödinger equation. Moreover, the study finds that word-of-mouth creates in the movie industry this phenomenon of finding outliers.
