This study was to analyze the effect of private education expenditures on financial performance. The data from 1,669 households were taken from the Korean labor and Income Panel Study. The major findings were as follows: (1) The mean of monthly private education expenditure was 257,400 won for all households. Almost 66% of households encountered an economic burden in paying for private education. (2) The mean of financial performance in all households was 31,420,000 won and those with higher assets showed the greatest financial performance (112.8 million won net gain). (3) The variables that significantly influenced on private education expenditures and the financial performance were different in all households. (4) The relationship between financial performance and private education expenditures was verified partially. The association was proved in the middle assets group.

Utility boiler operators seeking to gain the greatest economic advantage from their units are faced with three challenges, namely the obligatory light-up fuel costs, the additional expense of supplementary fuel firing should they wish to use a cheaper fuel that may be beyond the original burner manufacturer’s stability and combustion performance assurances and the immediate environmental impact of both. The novel use of plasma arc technology can provide a solution to these challenges. This paper introduces the work being undertaken through a joint collaboration between the EU, Kazahkstan and Russia in order to develop a tried and tested engineering methodology and a mathematical based application and sensitivity analysis approach for the design and optimisation stage of these plasma devices that, as a consequence, their assist in their universal introduction.

Korea and Japan have maintained an intimate relationship of economic exchange. However, even though both countries have made sound advances in the ASIAN market, they have not established mutually remarkable cooperative relations and advances in the ASIAN market. If korean companies with abundant experience and management ability provide able managers and skilled labor and if Japanese companies provide construction technology, capital and information, they could enjoy enomorous mutual benefits by advancing in the area of plant construction in foreign countries. Therefore, if they cooperate with each other by establishing complementary cooperation, both countries can gain an advantage in international competitiveness with western advanced countries.

Sustainable agriculture in Korea will gain important momentum by implementing The Direct Payment Scheme for Environmentally Friendly Agriculture in 1999. The farmers who want to participate in the program will be paid 530,000won/ha directly by the Government in return for engaging sustainable agriculture. The policy scheme which is a pilot program will be restricted to environmentally regulated areas to apply such as water supply protection zone, environmental protection districts and national parks. As a consequence of the policy, the supply of transitional organic agricultural products is expected to increase significantly. However the increased supply of low input agricultural products may have difficulties to find an appropriate marketing channel which is differentiated from the general agricultural product market. Development of an open market system for mass transaction of the low imput agricultural products is necessary. Also various government programs and projects which are designed for clean environment and regional community development must be integrated into the sustainable agriculture program to have synergy effects.

As proven petroleum reserves decline through continued production. exploration for new oil and gas resources will extend into environments which present significant economic risks arid technical hurdles. Since safety is one of the biggest concerns in drilling operations. the oil industry routinely trains its personnel in areas which are critical for safe and economical drilling procedures. One of these major areas is well control. A kick is defined as an unscheduled flow of formation fluids into a wellhole. A kick occurs whenever the resultant wellbore pressure is less than the formation pressure in an exposed zone capable of producing kick fluids. The typical causes of reduced wellbore pressure are insufficient mud weight. inadequate fluid level in the hole, and swabbing.(omitted)

In 2006, 41% of newly-married Korean men living in agriculture or fishery area were married to foreign wives. These foreign wives suffer social, cultural, and psychological maladjustment. They need support in understanding Korean culture & language, economic independence, and mental health. This horticultural therapy program (HT program) was practiced to help the foreign wives gain emotional stability, to help them adapt to rural society, and to help them improve the relationship with their families. The participants of this HT program were 10 foreign wives, 5 Chinese, 2 Vietnamese, 1 Japanese, 1 Thai, and 1 Filipina. Total sessions were 12, and each session lasted for two hours. This program started April and ended July in 2007. After this program, self-esteem of participants increased from 29.6 to 33.5, and stress decreased from 77.3 to 64.7. Participants also expressed sense of satisfaction and accomplishment after the program.

The COVID-19 pandemic has highlighted the risks of an over-concentration of supply chains in one country. It has motivated stakeholders to pursue diversification strategies. However, a paradox exists. Stakeholders have shied away from a complete decoupling and preferring to selectively enhance economic ties with China. This article explores this paradox by examining supply chain concentration in China as a form of asymmetric interdependence and the countermeasures from the U.S., Japan, Australia, and India to minimize vulnerabilities. It argues that while the COVID-19 disruptions have brought to light the risk of supply chain overconcentration in China, countermeasures are also driven by coercive diplomacy and the deepening U.S.-China rivalry. The paper also examines the feasibility of diversification efforts by focusing on the capacity and capabilities of alternative supply chain hubs. It finds that while states are actively seeking ways to prevent China from using asymmetric interdependence of supply chains and trade to gain political leverage, there are structural limits to the degree of diversification in the short to mid-term.

This paper utilizes a life-cycle overlapping-generations model to quantify the welfare effects of plans to postpone the depletion of the National Pension Fund. In order for the model to incorporate the rapidly changing demographic structure of Korea fully, we build and calibrate a model in transition directly. The model is considered suitable for analyzing the effects of demographic changes on the Korean economy and the effects of plans to change the National Pension System. According to a simulation of the model, to postpone the depletion of the National Pension Fund for 30 years, the premium rate must be increased to 18.3% from the current rate of 9%. By postponing the depletion of the fund reserve, young and future generations gain significantly at the expense of the older generations. The simulation results should be, however, interpreted as meaning that the current system is unjustifiably partial to the older generations. Moreover, given the current premium rate, it is desirable to strengthen the income-redistribution function of the National Pension System.

In past patriarchal societies, childbearing was considered the sole possession of women. At a time when women were struggling to move into society, the concept of parenting as the mainstay of the capitalist economic society and the head of the family has naturally been taken for granted by a woman named "housewife." Since the role of male babies is as important as that of females, Fathers are trying to promote the importance of the effects of fathers due to active participation in childcare and help change old perceptions of the past. Men also know the importance of participating in childcare in early childhood, but often do not know what their children want or why they cry due to lack of basic child care knowledge and lack of education. We tried to give fathers the meaning of indirect experience and change their perception of parenting by producing interactive VR content, which is completed with dad's participation, so that they can experience the child in person. In addition, through familiar childcare professional product advertisement and 360 degree stereo sound. It is made to immerse in the game to gain persuasive effect, inducing fathers to have interest and interest in childrearing.
