College tuition is a significant economic, social, and political issue in Korea. We conduct a Bayesian analysis of a hierarchical model to address the factors related to college tuition based on a survey data collected by Statistics Korea. A binary response variable is selected depending on if more than 70% of tuition costs are supported by parents, and a hierarchical Probit model is constructed with areas as groups. A set of explanatory variables is selected from a factor analysis of available variables in the survey. A Markov chain Monte Carlo algorithm is used to estimate parameters. From the analysis results, income and stress are significantly related to college tuition support from parents. Parents with high income tend to support children's college tuition and students with parents' financial support tend to be mentally less stressed; subsequently, this shows that the economic status of parents significantly affects the mental health of college students. Gender, a healthy life style, and college satisfaction are not significant factors. Comparing areas in terms of the degrees of correlation between stress/income and tuition support from parents, students in Kangwon-do are the most mentally stressed when parents' support is limited; in addition, the positive correlation between parents support and income is stronger in big cities compared to provincial areas.
The goal of this study was to examine the economic and cultural factors that influenced the intention of having a second child. In particular, this study intended to examine whether the factors related to the intention of having a child differed by the employment status of married women. The data for this study were drawn from the National Survey on the Trend of Marriage and Birth. This survey was conducted in 2005 by Korean Institute for Health and Social Affairs. The sample consisted of 690 married women who had one child(282 employed and 408 unemployed). The data were analyzed by logistic regression with SAS 9.1 program. The results showed that the employed women's intention of having a second child was affected by the husband's hours of housework, having a own mother(child's grandmother) and the perception of value of child. The employed women's intention of having a second child was affected by the perception of emotional value of child, and the sex of the first child. In sum, there were differences between the employed women and the unemployed women in the variables affecting the intention of having a second child. Perception of value of child was found important for both the employed and the unemployed women. Besides husband's hours of housework, having a mother and the needs for public support about child birth and rearing were found significant for the employed women. For the unemployed women, the costs of child care/education and the sex of the first child were found significant. The findings of this study suggested that different policy interventions be developed to satisfy the needs of the employed women and the unemployed women.
Objective : Until now, there have been no evidence-based guidelines produced for the mass screening of hyperlipidemia cases in Korea. This study was done to find the most efficient strategy for a hyperlipidemia-screening program among Korean adults, Method : Seven alternative strategies for hyperlipidemia screening were formulated and compared ir terms of cost-effectiveness. Cost and effectiveness were estimated from social perspectives and using a two-stage screening process (initial testing and additional testing for positives from the first test). A computerized database (based on persons who had visited a health promotion center in one teaching hospital for a routine health check-up) was used to determine the cost and the outcome of various strategies. Official data was used in calculating direct and indirect costs. Effectiveness was measured according to the number of persons who needed clinical intervention for hyperlipidemia. A stratified analysis, considering age group and sex, was then done. Sensitivity analyses, focusing on several uncertain parameters, were also done. Results : Of the seven test alternatives available, the most cost-effective strategy was a screening program, which consisted of an initial test of total cholesterol, high-density lipoprotein cholesterol and triglyceride. There was some variation in the rank of the cost-effectiveness ratios for the seven alternatives dependent on age group or gender. Conclusions : Current hyperlipidemia screening practice, for National Health Insurance beneficiaries, tests only the total cholesterol level with a cut-off value of 260mg/dl as an initial screening test. It is not the best strategy for cost-effectiveness, and should be modified. Different screening strategies taking age group and sex into account should be developed and used for the efficient mass screening of hyperlipidemia cases among Korean adults.
The characteristics of performing arts differ from those of utilitarian goods in terms of economics. Factors other than price need to be considered to understand the demand for performing arts. Audience surveys as well as econometric demand studies have confirmed that socio-economic factors such as age, income, employment, and education are major determinants of the demand for performing arts. This study focused on the attributes of concerts rather than consumer characteristics to determine the concerts audiences select in terms of transaction cost. Genre, price, internet search trends, and the purpose of performance as well as price are tested as determinants of demand by using the data set for a major concert hall in Seoul. Genre and the specific purpose of concerts influence the demand for concerts. Internet search trends of the performer are used as indicators of popularity and information exposure, which are positively correlated with demand. This result supports the hypothesis that larger audiences would attend concerts that require lower information search costs. To note, price has a positive effect on demand in the higher price range, which means that concerts at higher prices attract larger audiences, whereas normal goods have a negative slope in the demand curve. This result can be explained by the hypothesis that consumers use price as an indicator of the quality expected of a concert. Transaction cost for selecting classical concerts thus forms an inverse-U shape curve against ticket price. These results provide some explanation of why audiences of classical music choose to attend concerts at high ticket prices while offering evidence in favor of the hypothesis that performing arts are selected in a social context.
What is particularly noteworthy from Korean and foreign railway tunnel disaster prevention standards is that for the sake of rapid evacuation, more stringent standards for provision of evacuation passages, which require high cost, are being applied. Korean standards stipulate that passage installation should be determined in accordance with the level of risk through a QRA analysis of each tunnel with 1km or longer length. As, however, detailed application criteria as fire occurrence probability, fire occurrence scenario, size of fires and evaluation criteria for level of social risk are not available, additional costs may be incurred due to excessive design. Thus, standards of an appropriate level need to be established. With this backdrop, this study selects detailed application conditions of a reasonable and appropriate level through a study and analysis of relevant documents and analyzes the maximum length of tunnels to which the application of evacuation passages, or the application major evacuation promotion facilities, can be relaxed, together with a QRA analysis of model tunnels (for high speed rail) with different tunnel lengths. In addition, the QRA results on tunnels, including those on the Honam high-speed rail, and analysis results for the model tunnels, are compiled, ; the ultimate results are compared with Korean and other countries' standards related to evacuation promotion facilities, As a result, The appropriateness of application standards are reviewed. These results are expected to be utilized as basic material for establishing a reasonable disaster prevention plan that will consider safety and economies.

In order to reduce the social and economic costs due to the increase in dementia patients, which is a representative senile disease in an aging society, it will be important to prevent dementia and to detect and treat early in high-risk groups. This study reported the results of treatment for the elderly with high risk of dementia and depression who received Korean medicine (KM) treatment in 9 KM clinics. Medical charts were surveyed on 116 patients with high risk of dementia and depression who received KM treatment at 9 KM clinics in Gangseo-gu from September 1, 2020 to December 31, 2020. The majority of the patients were female(76.72%), the average age was 71.66±7.18 years old, and the average education level was 8.96±3.91 years. The average treatment period was 61.47±10.30 days, the average number of treatments was 15.38±1.06 times, and both acupuncture and herbal medicine were administered. After receiving KM treatment, cognitive assessment scores such as MMSE-DS and MoCA-K, depression-related GDSSF-K score, dementia knowledge, attitude, and preventive behavior, blood debilitation scale, and GQOL-D score were improved compared to before. There was no specific adverse reaction except that one patient with elevated AST and ALT levels was observed. This study showed improvement in cognitive function, depression, dementia-related scale, and quality of life in high-risk groups for dementia and depression over 60 years old who received KM treatment. More systematic and large-scale planned clinical studies will be needed.
Our society is aging rapidly. In this super-aged society, the increase in healthcare costs are considered a national problem that undermines the sustainability of social security. Various services for healthcare for the elderly have been promoted to address this. However, most of them have focused on healthcare after the outbreak of chronic diseases and lack preventive healthcare. Most of the preventive healthcare projects are only pilots. In this paper, the current status of health care services for senior citizens at home and abroad was analyzed and based on this, the limitations and improvements were analyzed to propose the establishment of IoT-based Total Silver Care Center. IoT-based Total Silver Care Center may be conveniently monitored the health status of the elderly through various sensors, medical devices, and smart bands. And based on this, it can improve the quality of nursing services through time-saving and work efficiency of nursing providers. In addition, health care interventions may be provided in a timely manner if there is a change in the health status of users. And real-time imaging systems can help overcome mental difficulties.
The collection and transfer of records is a very basic stage in the whole process of records and archives management. However they are regarded as an non-professional art of work in records management that are performed easily by everyone. Therefore they have been treated not properly in the scholarly discussion of archival sciences in Korea. The collection and transfer of records play an active role in the making of effective administrative system, in accumulating and sharing the knowledge and informations of political, economical, social and cultural values. On the basis of proper collection and transfer of records our democracy can operate regularly and our daily experiences can be preserved as historical resources. For the optimal-functioned collection and transfer of public records the archivists for this task must have a comprehensive understanding of whole process of records management and possess suitable professional skills. Moreover there are many sorts of preliminary works needed for this task, as follows: an accurate defining of administrative organizations and their tasks, thorough understanding of records management institutions on their own competence and ability, and the establishment of technical standards for their tasks. Additionally the archivists are able not only to consider the present informational and evidential values of the records, but also the historical values. It can be said that the collection and transfer of records is a "synthesis of records management skills" exerted by an archivist. According to the newly established law of public records management, the collection and transfer of public records must be registered at first electronically. Through this procedure the whole contents of produced and transmitted records, which are to be transferred, can be reported in detail. By means of this report the archival institutions and the archivists can trace back the each items of records(archives) and the result of their arrangement to identify a certain object. There are also new storage strategies employed to increase the whole sum of stored informations, i. e. records and archives, in spite of reducing the storage costs. It will be achieved by differentiations of the preservation methods for each sorts of records by the criteria of storage-period, -place, and -method. Many supplementary methods are also prepared to help the collection of important records(archives) in a complete structure and form. To let this new concept and system of collection and transfer of records operate properly, a number of professional archivists should be posted in the needed places throughout the whole administrative body. Their training must be also updated for the newly defined task of collection and transfer of records.

This study was conducted 1) to investigate the effects of treatment and other factors on the quality of life of thyroid cancer surgical patients and 2) to provide fundamental data for development of an intervention and symptom management program to improve the quality of life of those patients. A total of 76 patients who were diagnosed with thyroid cancer and underwent thyroidectomy from July 2013 to December 2014 participated in this study. To investigate the factors affecting quality of life, a t-test and ANOVA analyses were conducted, after which multiple regression analysis was performed. The results were statistically significant between preoperative and one month after surgery of sex, cancer history, fatigue, and quality of life until 3 months after surgery of stage, cancer history, anxiety, and pain. Multiple regression analysis showed that the most influential factors affecting the quality of life were depression and fatigue at one month prior to and after surgery and anxiety at three months after surgery, while no factors were found to be influential at six months after surgery. Overall, the results of this study suggested that it is imperative to manage depression and fatigue one month prior to and after surgery to reduce the physical and psychological pain experienced by thyroid cancer patients. Moreover, three months after the surgery, anxiety should be closely monitored and controlled to improve the quality of life of the patients. This approach is expected to reduce the burden on the health care system and social costs, which will positively affect public health.
An offshore waste disposal facility refers to a landfill site for final landfilling of stabilized inorganic solid waste such as land and marine waste incineration materials, and the aim of such a facility is to solve the problem of insufficient waste disposal space on land and create and develop environmentally friendly marine spaces. The purpose of this study is to prepare guidelines for the construction of offshore waste disposal facilities, which reflect the need and importance of paying sufficient heed to environmental considerations from the initial stage of the project, in order to investigate, predict, and assess how such guidelines will affect the marine environment in relation to the construction of offshore waste disposal facilities, with the goal of minimizing the impact on and damage to the environment. For the purpose of this research, guidelines focusing on the construction of offshore waste disposal facilities were derived through an analysis of domestic cases and similar foreign cases and an assessment of their level of compliance with existing EIA guidelines through the operation of a discussion forum. In order to review the EIA report on similar cases in Korea, 17 EIA documents (2005~2016) for dredged soil dumping areas and ash ponds of thermal power plants were analyzed to investigate the status of marine organisms, marine physics, marine water quality, and marine sediment and to understand what types of problems can occur and what improvement measures can be taken. The purpose of these guidelines were to minimize damage to the marine environment by promoting EIA protocols in accordance with scientific and systematic procedures, to reduce the consultation period related to projects, to resolve social conflicts, and to reduce economic costs.
