The purposes of the study were to investigate the effects of the debt burden which was measured objectively, the types of debts and socio-economic characteristics on the subjective debt burden of households. The questionaires for 457 households who hold some debts were analyzed using t-test, ANOVA and Duncan’s multiple range teat. The major finding are summarized as follows: (1) the objective debt burdens which were measured by three variables, that is monthly debt repayment, the ratio of debt repayment to household income and total debt amount, affected the subjective debt burden. The households in which the monthly debt repayment was over 200 thousand won, the debt repayment was over 20% of the household income and the total debt amount was over 15 minion won felt higher debt burden. (2) the types of debts, which were classified into four groups such as debts from financial institutes, debts from private sources, credit card debts and debt from retailers, influenced differently the subjective debt burden. Holding debts from financial institutes and debts from private sources increased the subjective debt burden whereas holding credit card debts and debt from retailers did not. (3) the level of subjective debt burden were different according to household income, change in income due to IMF crisis, financial assets, home ownership, residence, householder’s age, job and educational levee. Based on the results, criterion for household’s debt management were suggested.

It is becoming increasingly difficult for colleges to recruit new students to their full capacity. The increase of the withdrawal rate drives these colleges into crisis yet little has been done about it, because students with great possibility to withdraw enter colleges and old measures to stop them from dropping out hardly work. This study attempts to grope new measures to prevent dropout from college. To do this, I investigated withdrawal rate by college admission types and suggested measures to reduce withdrawal rate by incorporating the results of the investigation into admission procedures. I also compared the different types of admission in students satisfaction with college life and withdrawal rate, and suggested the measures to alleviated withdrawal rate. I expect the suggestions made in this study would be used effectively to reduce the withdrawal in colleges.

The purpose of the study is to know the current status of the assets backed securities(ABS) in Korea. ABS enables banks, depository institutions, finance companies, and other corporations to liquefy their assets (i.e., raise cash by borrowing against assets) and develop new sources of capital. ABS are bonds that represent pools of loans of similar types, duration and interest rates. By selling their loans to SPC, the originator recover cash quickly, enabling them to make more loans. The ABS market in Korea has grown so rapidly since Financial Crisis in Korea. In current, So many different types of loans are securitized and sold in the investment markets. For more prospering ABS in Korea, some problems in ABS should be make up.

This study analyzes 419 fake news items published in India, a fake-news-prone country, to identify the major themes, content types, and sources of social media fake news. The results show that fake news shared on social media has six major themes: health, religion, politics, crime, entertainment, and miscellaneous; eight types of content: text, photo, audio, and video, text & photo, text & video, photo & video, and text & photo & video; and two main sources: online sources and the mainstream media. Health-related fake news is more common only during a health crisis, whereas fake news related to religion and politics seems more prevalent, emerging from online media. Text & photo and text & video have three-fourths of the total share of fake news, and most of them are from online media: online media is the main source of fake news on social media as well. On the other hand, mainstream media mostly produces political fake news. This study, presenting some novel findings that may help researchers to understand and policymakers to control fake news on social media, invites more academic investigations of religious and political fake news in India. Two important limitations of this study are related to the data source and data collection period, which may have an impact on the results.

There is no standardized concept of "at-risk youth," but from an overall perspective, they are youth exposed to various crises. "At-risk youth" are categorized into personal, familial, educational, and social crisis areas, encompassing factors such as family background, educational difficulties, and mental health issues. There is a dance piece that addresses these "at-risk youth. Matthew Bourne created a dance piece that addresses "at-risk youth" in <Romeo + Juliet>. Currently, Matthew Bourne is a popular choreographer from England who reflects certain social phenomena and does not differentiate between classic art and public art. In 2019, Matthew Bourne collaborated with young creators to reinterpret <Romeo + Juliet> as a narrative centered around youth. In this dance work, youth is both the subject and the expression of the story. In <Romeo + Juliet>, "at-risk youth" are depicted in various forms. The work explores mental health issues including homosexuality, trauma, and depression among teenagers, as well as societal issues such as violence and weapons. The stage depicted how teenagers perceive themselves and how they navigate the challenges faced by "at-risk youth". We would like to interpret the work in relation to the types of "at-risk youth" and the expression methods of the performance. Of course, there may be differences when examining performance cases in other countries compared to youth in Korean society. However, It has meaning in itself to analyze Matthew Bourne's <Romeo + Juliet> in various ways in relation to "at-risk youth" and to examine social phenomena from a broader perspective through this.

In modern society, the number of industrial customers using equipment sensitive particularly to voltage sags is rapidly increasing. As voltage sags can cause loss of information as well as false operation of the control device, it results in the vast economic damage in industrial processes. One way to mitigate voltage sags in the sensitive loads is the installation of distributed generation (DGs) on the periphery of these loads. In addition, renewable energy sources are currently in the spot light as the potential solution for the energy crisis and environmental issues. In particular, wind power generation which is connected to a grid is rising rapidly because it is energy efficient and also economically feasible compared to other renewable energy sources. On the basis of the above information, in this paper, with Wind Turbine Generators (WTGs) installed nearby the sensitive load, the analysis of the mitigating effect comparison by types of WTGs is performed using voltage sag assessment on the IEEE-30 bus test system. That is, the areas of vulnerability according to types of WTGs are expected to be different by how much reactive power is produced or consumed as WTG reactive power capability is related to the types of WTGs. Using the concept of 'Vulnerable area' with the failure rate for buses and lines, the annual number of voltage sags at the sensitive load with the installation of WTGs per type is studied. This research will be anticipated to be useful data when determining the interconnection of wind power generation in the power system with the consideration of voltage sags.

In the present study, effects of tree-stream turbulence and surface trip wire on the flow past a sphere at $Re\;=\;0.4\;{\times}\;10^5\;{\sim}\;2.8\;{\times}\;10^5$ are investigated through wind tunnel experiments. Various types of grids are installed upstream of the sphere in order to change the tree-stream turbulence intensity. In the case of surface trip wire, 0.5mm and 2mm trip wires are attached from $20^{\circ}\;{\sim}\;90^{\circ}$ at $10^{\circ}$ interval along the streamwise direction. To investigate the flow around a sphere, drag measurement using a load cell, surface-pressure measurement, surface visualization using oil-flow pattern and near-wall velocity measurement using an I-type hot-wire probe are conducted. In the variation of free-stream turbulence, the critical Reynolds number decreases and drag crisis occurs earlier with increasing turbulence intensity. With increasing Reynolds number, the laminar separation point moves downstream, but the reattachment point after laminar separation and the main separation point are fixed, resulting in constant drag coefficient at each free-stream turbulence intensity. At the supercritical regime, as Reynolds number is further increased, the separation bubble is regressed but the reattachment and the main separation points are fixed. In the case of surface trip wire directly disturbing the boundary layer flow, the critical Reynolds number decreases further with trip wire located more downstream. However, the drag coefficient after drag crisis remains constant irrespective of the trip location.

Better understanding of the complex factors leading to human diseases will be necessary for both long term prevention and for managing short and long-term health problems. The underlying causes, leading to a global health crisis in both acute and chronic diseases, include finite global health care resources for sustained healthy human survival, the population explosion, increased environmental pollution, decreased clean air, water, food distribution, diminishing opportunities for human self-esteem, increased median life span, and the interconnection of infectious and chronic diseases. The transition of our pre-human nutritional requirements for survival to our current culturally-shaped diet has created a biologically-mismatched human dietary experience. While individual genetic, gender, and developmental stage factors contribute to human diseases, various environmental and culturally-determined factors are now contributing to both acute and chronic diseases. The transition from the hunter-gatherer to an agricultural-dependent human being has brought about a global crisis in human health. Initially, early humans ate seasonally-dependent and calorically-restricted foods, during the day, in a "feast or famine" manner. Today, modern humans eat diets of caloric abundance, at all times of the day, with foods of all seasons and from all parts of the world, that have been processed and which have been contaminated by all kinds of factors. No longer can one view, as distinct, infectious agent-related human acute diseases from chronic diseases. Moreover, while dietary and environmental chemicals could, in principle, cause disease pathogenesis by mutagenic and cytotoxic mechanisms, the primary cause is via "epigenetic", or altered gene expression, modifications in the three types of cells (e.g., adult stem; progenitor and terminally-differentiated cells of each organ) during all stages of human development. Even more significantly, alteration in the quantity of adult stem cells during early development by epigenetic chemicals could either increase or decrease the risk to various stem cell-based diseases, such as cancer, later in life. A new concept, the Barker hypothesis, has emerged that indicates pre-natal maternal dietary exposures can now affect diseases later in life. Examples from the studies of the atomic bomb survivors should illustrate this insight.

The purpose of this study is to examine types and characteristics of self-regulation which explain how individual diabetic patients determine their behavior in terms of diabetes management. Based on the results, we proposed the management method of the diabetic patients. As a method of analyzing the subjectivity of each item, a Q method study was used. There were 38 subjects who were treated with oral drugs or insulin injections, but not currently hospitalized. And 40 statements in Q samples were classified in the form of a normal distribution using a 9-point scale. Research results regarding self-regulation in diabetic patients, type 1 is evidence-based compliance, type 2 is crisis responding denial reaction, type 3 is information-based orientation to relationship, type 4 is independent practice, and type 5 is willingness deficit impulse reaction. Therefore, for effective management of diabetic patients, it is necessary to understand the characteristics of each type of self-regulation and develop a program that reflects motivation for diabetes management, improvement of confidence, and countermeasures for negative emotions related to disease.

At a time when Korea and the rest of the world recently faced the unprecedented situation of "COVID-19," the view of actively "disclosure" of information to prevent the spread of infectious diseases is at odds with the view of "protecting" personal information as these social measures are coupled with the infringement of individuals' basic rights. In order to see the nation's response to the infectious disease crisis, we examined the current status and characteristics of public records according to crisis alert levels based on the manual for responding to infectious disease. Especially we analyzed the types and disclosure status of records containing personal information. For detecting personal information-related issues on news media, we collected online news articles and performed text anlaysis. Through this, we reviewed the problems of record management including personal information and suggested improvement points from the perspective of the life cycle of records: collect, manage, and dispose of them.
