Though the British shipbuilding industry dominated the world market in the 19th century, it could not avoid the repetitive rise and fall of the unemployment following after the cyclical fluctuations. Without challenging the employers' rights to fire at will, the boilermakers maintained their own unemployment insurance in order to escape from the new poverty law system. In the beginning the craft union could continue their own unemployment insurance under the National Insurance Act of 1911, but it went into bankruptcy under the massive unemployment of the 1920s and the attacks of shipyard employers. The Act of 1911 was a step towards social solidarity in that it spread the risks beyond the occupational boundaries, applying unemployment insurance to unskilled and non-union workers, and the employer and the government also paid the premium. In the Great Depression, the shipyard trade unions demanded that the government should intervene in the shipbuilding market to provide jobs, but it was not accepted by the government. The government responded only to the another demand of the union for the maintenance, which could be achieved partially through the abnormal operation of the insurance system, abandoning the insurance principle. After all, unemployment in the shipbuilding industry was resolved only by the expansion of rearmaments and the outbreak of World War II. From the 19th century to the World War II, the craft unions did not challenge the employers' right to fire at will and did not attempt to regulate dismissal procedures or make any demands on dismissal compensations. During interwar periods rules and practices related with weak employment protection - one of the main features of the liberal employment adjustment institution - were prevalent in Britain. The principle of 'employment at will' could survive through the historical events such as the World War I, II as the operation of the unemployment insurance became the focus of the social conflicts.

This study examines the employment relations of TNC subsidiaries in Central and Eastern Europe(CEE). Specifically, this study analyzes the employment relations of Volkswagen subsidiaries, which has led the restructuring the CEE's automobile industry since the collapse of socialist regimes, and Hyundai subsidiaries, which has sought to cast employment relations through Greenfield Investment as a latecomer. After the collapse of socialism, with the massive inflow of foreign direct investment and the social legacy of weak labor unions, CEE has been included in the global production network as low-wage production base. Both VW and Hyundai have entered the CEE with their own characteristics and global strategies that have been developed in their home countries and have developed the local production. In the process, both have formed local employment relations, combining low-wage, unstable employment, and weak labor unions of CEE under their own strategy. In recent years, however, it has been doubtful of the sustainability of employment relations based on the advantages of low-wage production bases, as the pools of low-wage workforce decline and new union movements occur in CEE. These changes in CEE are an indication of the inherent contradiction of low-wage production base strategies.

This study examines the characteristics of population ageing and the employment of aged workers in Seoul. Population indexes such as aged/child ratio and longevity degree are analyzed to identify the time-spatial changes and differentiation of population ageing by Gu. Job offerers, job seekers and employees related to the aged workers are also analyzed using data from Center of Job Placement for the Aged in Seoul. The results indicate that population ageing of Seoul has progressed faster than other regions in recent years. In addition, regional differences in tendency of population ageing is obvious even within Seoul. The percentage of unskilled laborer is much higher in Seoul compared with other regions. There is geographical differentiation in employment of aged workers among regions within Seoul. The employment opportunity of the aged is high in core economic areas of Seoul, while low in the outer residential area. This shows geographical mismatch between job offerers and seekers, which means that it is difficult for aged workers to get the jobs near to their residence. Accordingly, governmental support and intervention is needed considering their lower mobility.

The formation of , $\beta$-quartz solid solution in the $LiO_2-Al_2O_3-SiO_2$glasses containing $TiO_{2}$ and $ZrO_{2}$ as nucleating agents was investigated for various temperatures and times. Linear thermal expansion coefficients of base glasses and crystallized glasses were $45\sim 55 \times 10^{-7} \textrm{cm}/^{\circ}C$ and $ -8\sim +8 \times 10^{-7}\textrm{cm}/^{\circ}C$ ($25^{\circ}C \sim 525^{\circ}C$), respectively. The crystal phase formed by heat-treatment below $900^{\circ}C$was , $\beta$--quartz solid solution, and the crystal sizes were less than 0.21m. On the other hand, the crystal size of the base glasses containing 3.5 wt% MgO is relatively uniform and is independent with temperature. The specimen containing 3.5 wt% ZnO shows a minimum crystal size(O.l8$\mu \textrm{m}$), and it strongly depends on temperature of heat-treatment.

The crystallization method determines the material quality and consequent device performance. This paper investigates the crystallization of a-Si:H films on various substrate materials and analyzes the crystallization effect with and without using eutectic forming metals. From the examinations of the various substrate materials, a metal Mo was selected for the a-Si:H films growth and subsequent crystallization of it. For a sample without any eutectic metal layer, we observed grain size of $0.8{\mu}m$ after $1100^{\circ}C$ anneal treatment. To reduce crystallization temperature, we used some of the eutectic forming metals such as Au, Al and Ag. Poly-Si films with grain size over $10{\mu}m$ and (111) preferential plains were achieved using a premetal layer of Au at an anneal temperature of $700^{\circ}C$. The various crystallization effects of eutectic metal thickness and type were investigated for photovoltaic (PV) device applications.

In this study, we predicted the employment ratio by the export industry using various machine learning methods and verified whether the prediction performance is improved by applying the constrained forecast combination method to these predicted values. In particular, the constrained forecast combination method is known to improve the prediction accuracy and stability by imposing the sum of predicted values' weights up to one. In addition, this study considered various variables affecting the employment ratio of each industry, and so we adopted recursive feature elimination method that allows efficient use of machine learning methods. As a result, the constrained forecast combination showed more accurate prediction performance than the predicted values of the machine learning methods, and in particular, the stability of the prediction performance of the constrained forecast combination was higher than that of other machine learning methods.

After industrialization, the labor force participation rates of women, especially married women is drastically increasing. So, this study was designed to analyze the determinants of married women's employment status considered. For this, the determinants of married women's employment status were divided into individual-related, children-related, household-related and job-related variables to establish the research models. Based on this, the following results were drawn from a multinominal logistic regression analysis of the determinants of married women's employment status. First, an analysis of individual-related variable showed that married women had the employment status of labor wages with residence in the center of the city and high academic background. Second, an analysis of children-related variable showed that they had the employment status of labor wages with many their children and no their children under the age of six. Third, an analysis of household-related variable showed that they had the self-employment status of labor wages with nuclear family and few income earners of family members. Finally, an analysis of job-related variable showed that they had the employment status of labor wages when they got a job before they got married, their husband didn't get a job, and their husband worked in a professional field. As for findings stated above, as there was a difference in the determinants of married women's employment status, the ways for improvement in the married women's employment status would be suggested as follows. First, married women with young children have the low employment status, basically, requiring problem-solving ways for this because the housekeeping and child-rearing burden caused by marriage and childbirth are factors that continue to obstruct a job. For this, the flexible working hours system, which housekeeping and child-rearing can harmonize with economic activities like developed countries, needs to be activated. But the activation of such flexible working system will produce actual results under institutional protection, such as a related-protection law. Second, the Leave of Child Care System is debated as one of the most representatively systems that housekeeping can harmonize with economic activities. Now, although the System is legislated, the use is very poor.

This study examines the housing-related characteristics of unmarried youth using occupational history data from the 10th-14th (2016-2020) youth panel (YP2007) of the Korea Employment Information Service, and the characteristics of housing and employment. Their effect on marriage intention was empirically analyzed. The results of the analysis show that highly educated people, high-wage workers, household heads or economically independent young people, and young people in good financial conditions have a high willingness to marry. Their economic conditions are very important factors. Among the young employed who have become economically independent from their parents, full-time permanent workers, workers at large corporations, and highly waged youth showed a strong desire to get married. On the contrary, young people who are insecure temporary/daily workers, workers at small firms, and low-wage workers show a low willingness to marry. In conclusion, the results imply that young people who are in a vulnerable state in the labor market are giving up or delaying their marriage. Therefore, it is necessary to enhance policies to provide better employment opportunities for youth and, simultaneously, revamp the policy measures to enhance housing conditions.

The COVID-19 pandemic has so far given the world a great shock and fear that cannot be compared to other infectious diseases, and local economies are experiencing a serious economic crisis accordingly. This paper examines the regional characteristics of economic recession and resilience due to the COVID-19 pandemic, focusing on the employment fluctuations in 85 cities nationwide. Although the overall trend is in line with national employment indicators, there are some differences in the shock response and the recovery of employment in individual cities. The difference between cities is somewhat greater in the resilience of the recovery stage than the resistance, which is the shock-response stage. In terms of resilience, cities in the capital area have relatively good condition compared to cities in the non-capital area. The weak resilience of large cities such as Seoul, which has a high population density, can be explained to be the effect of the COVID-19 pandemic of infectious diseases. Regarding the economic structure of the city, the ratio of service and sales workers, wholesalers and retailers, and food and lodging businesses are analyzed as valid explanatory variables for the resilience of cities.

The temperature and the composition dependence of the dielectric properties of the solid solution materials in the system $xBa(Zn_{1/3}Nb_{2/3})O_{3}\[BZN]-(1-x)\Sr(Zn_{1/3}Nb{2/3)O_{3}\[SZN]$ at microwave frequency was studied. The dielectric constant and unloaded Q were $40.5{\pm}0.5,5980{\pm}100$ respectively for BZN at 10 GHz and $36.9{\pm}0.5,2700{\pm}100$ for SZN at 10.2GHz. The temperature coefficient of the resonant frequency was $+27.5ppm/{\circ}C$ for BZN and $-39.1ppm/{\circ}C$ for SZN. The results also showed that 0.3 BZN-0.7 SZN is the most temperature-stable composition among xBZN-(1-x) SZN solid solutions. In this case, the dielectric constant, the unloaded Q and $\tau_{f}$ at 9.8GHz were $41.5{\pm}0.2,2920{\pm}100$ and $-3.5ppm/{\circ}C$, respectively.
