Introducing a concept of 'the Effect of My Mom's Friend's Son'(MMFS Effect) into the conventional job search theory to develop it further, we try to estimate its effects on the hazard rate of youth pre-employment duration with some proxy variables such as his/her parents' schooling, monthly temporary/daily workers ratio, monthly average wage differentials between the workers of large and small firms. The results confirm us the fact that so called 'MMFS Effect' has been strengthened gradually up to recently. Their policy implications are as followings. Firstly, from the standpoint of shortening job searching period of youth and raising the hazard rate of their unemployment, the trend that the differentials of wages and quality of jobs in the labor market are expanding continuously is not desirable at all. Secondly, the problems of youth unemployment cannot be solved easily only by providing correct and relevant informations about the labor markets simply.

There have been some problems of high labor. low productivity in the existing systems of bonsai cultivation. This study was conducted to cultivate a large quantity of hig-quality bonsai through the development of bottom irrigation system and management method. Bonsai placed on the FRP bed were grown very well by bottom irrigation system compared with direct watering and sprinkler system. It was concluded that bottom irrigation system was possible to reduce considerable manual labor and produce mass production of high-quality bonsai within shorter periods. This research was finally found that the growth was significantly better and earlier production was certain in the vinyl house, had another advantage which could cultivate less cold-resistant species and therefore broadened a range of species selection for market supply. Cultivation techniques by the use of vinyl house and bottom irrigation system developed was quite effective for early production of bonsai as well as for high productive and value added. This project developed a new practical techniques and systems which can make mass and early production of bonsai with high quality through input of less labor. Interest in bonsai is now expanding in landscape horticulture and other fields concerned, and bonsai export of our country is also increasing. Results from this research will make a great contribution to enhancing of bonsai cultivator's competitive position in world markets and to improving of their annual income.

The purpose of this study was to investigate the influential factors on the job mobility types and patterns of baby boomers over the past 15 years. Sequential analysis was conducted to analyze the data that were derived from Wave 1~15(1998~2013) of Korean Labor and Income Panel Study(KLIPS). In particular, we analyzed the job mobility types and frequency, conversion analysis, probability, and significance rate. The results were as follows: firstly, proportional rates of male baby boomer workers such as technical, functional, and agriculture workers were higher than those of professionals and semi-professionals, whereas in case of female baby boomer workers, proportional rate of office workers were lower than those of service and sales workers. It was showed that functional and labor workers significantly higher than others. We found that after retiring, they left their job to search for farming job or choose to work in secondary labor markets. We suggested that the retirement support system and management system should be designed and conducted in a good manner.

This study aims to comprehensively assess the phenomenon of structural unemployment, with a specific emphasis on unemployment resulting from spatial mismatch, while also exploring potential solutions. Spatial mismatch unemployment presents a unique challenge distinct from unemployment stemming from demand deficient, thus requiring a more multifaceted approach beyond the efforts of individual businesses and national economic recovery policy. To underscore the importance of addressing spatial mismatch, this research seeks to quantify its contribution to overall unemployment. Additionally, we evaluate the effectiveness of local labor markets, a prominent mechanism for alleviating spatial mismatch, categorized by occupation, to assess their effectiveness for addressing this issue. Through this analysis, our study advocates for the development of comprehensive policies within the realm of job-related initiatives, including spatial alignment through inter-regional collaborations, in conjunction with region-specific policies and strategies for job creation.

In the path of agricultural development, agricultural mechanization has played some decisive roles such as protecting natural disaster, substitution of labor shortage in agricultural production and so on. In making our country's agricultural mechanization plan, Japanese agricultural mechanization policy has been frequently referred to but it's very hard to find informative data for systematic analysis of the mechanization policy. In this paper it was tried to analyze the resent trend in Japanese agricultural mechanization policy and it's performance with many materials published in Japan. As the results, four things are recommended to be considered in making Korean agricultural mechanization policy. First, faster enlargement of agricultural machinery size in Korea might be very harmful to drop down agricultural production cost. Second, diverse utilization methods of agricultural machniery should be introduced. Third, a marketing of the used agricultural machinery must be activated to reduce agricultural production cost. Lastly, the joint R & D for developing low price agricultural machniery is necessary for small markets.

This paper compares income and consumption inequalities in Korea and applies the permanent income hypothesis to interpret the linkage between the two inequalities. Income inequality has been increasing since 1990 while consumption inequality had been decreasing until the early 2000s when the two inequalities started to co-move. Permanent income hypothesis explains reasonably well the consumption pattern in the recent period, which reflects the increased access to asset markets by the Korean households. Consequently, the co-movement of income and consumption inequalities in the recent period implies that inequality in permanent income components are fluctuating.

This study was carried out to investigate the effect of changes in child care technology on mother-child contact by using all sorts of literature such as diaries, documents or statistical data. Child care technologies began to change during the 1960's. Diverse goods and services such as baby dry milk, paper diapers and child care centers have made child care easier and saved a great deal of time. This has also allowed women to participate in labor markets easily despite rearing children. But maternal contact with children have declined due to new goods and services and this trend is especially prevalent in early childhood. It could be supported that the convenience of rearing rather than the needs of children like as attachment to maternity primarily was considered in technological change. From this results it was suggested that we should develop the alternative child care technologies which better reflect children's needs.

East Asia, for long the epitome of successful engagement in trade, faces serious challenges: technological change that may threaten the very model of labor intensive industrialization and a backlash against globalization that may reduce access to important markets. The analysis in this article suggests that how East Asia copes with these global challenges will depend on how it addresses three more proximate national and regional challenges. The first is the emergence of China as a global trade giant, which is fundamentally altering the trading patterns and opportunities of its neighbors. The second is the asymmetric implementation of national reform - in goods trade and investment versus services - which is affecting the evolution of comparative advantage and productivity in each country. The third is the divergence between the relatively shallow and fragmented agreements that regulate the region's trade and investment and the growing importance of regional and global value chains as crucial drivers of productivity growth.

This study aims to analyze the correlation between semiconductor innovation and market dominance in the mobility electric vehicle industry. To this end, the study presentsstrategiesthat provide low-price competitiveness along with high-value creation in the electric vehicle and semiconductor markets. The first change in the era of high interest rates is to overcome the crisis of survival for value. Furthermore, the study acknowledges the ongoing second wave of change as the digital technology's value continues to rise, and companies experience decreased productivity due to rising ESG labor costs. The study analyzed price competitiveness in the context of the increased adoption of electric vehicles and the integration of semiconductor prices, proving that Tesla and Samsung Semiconductor have developed technology to dominate the market, with appropriate low-cost strategies applied as the value of innovation declines.
