Vanillin is the primary flavor and fragrance compound of natural vanilla and is extensively used in the food, beverage, perfumery, pharmaceutical industries, and other applications. Vanillin can be produced by chemical synthesis, extraction from vanilla plants, microbial bioconversion of natural precursors to vanillin, and direct fermentation using glucose. Currently, most commercially available vanillin is produced by extraction from cured vanilla pods and by chemical synthesis using guaiacol and glyoxylic acid as starting raw materials. Due to environmental issues, health complaints, preference for natural sources, and the limited supply and soaring price of natural vanilla, biotechnology-based vanillin production is regarded as a promising alternative. As many microorganisms that are able to metabolize several natural precursors, including ferulic acid, eugenol, isoeugenol, and lignin, and accumulate vanillin, have been screened and evaluated, myriad strategies and efforts have been employed for the development of commercially viable production technology. This review outlines the recent advances in the biotechnological production of natural vanillin with the use of these natural precursors. Moreover, it highlights the recent engineering approaches for the production of natural vanillin from renewable carbon sources based on the de novo biosynthetic pathway of vanillin from glucose, together with appropriate solution strategies to overcome the challenges posed to increase production titers.

As a multicultural society, is it right to adhere to the prevention principle of permanent migration of migrant workers? We need to try to do a little more calm consideration on the prevention principle for permanent migration rather than in terms of human right and emotional aspect. Even though there is a suggestion that we need to decrease the proportion of 3D Jobs by improving industrial demand, migrant workers can be an alternative in that we need a solution unless we can be freed from 3D Jobs. The prevention principle for permanent migration not only is against the trend of multicultural society but also blocks the opportunity for migrant workers to share their skills and knowledge taught in our country. In addition, with the society aging, that the permanent migration of migrant workers can be proper channels to supply young labor force should be kept in mind. In addition to this practical aspect, considering that all human beings are equal and with dignity and unequal conditions that migrant workers undergo require empathetic viewpoint, the prevention principle should be amended.

A porous material which can contain liquid perfume was manufactured by adding 1~4 wt% of polysiloxane into a composite containing 20 ㎛ Ag powder and 30 wt% of 53 ㎛ salt, sintering for 60 min at 750℃, and melting salt selectively. The changes in pore, hardness, and microstructure were confirmed according to the polysiloxane content both before and after sintering. The manufactured silver liquid container was formed with open pores both before and after sintering, and the container shrunk by 2~7 % in both perpendicular and parallel directions after sintering. Vickers hardness was increased after sintering and was doubled when 2 wt% of polysiloxane was added. In case of the microstructure, the surface condition of the silver liquid container became darker according to the polysiloxane content, and the pore size was decreased from 50 ㎛ to under 10 ㎛. The composition distribution result revealed an even distribution when 2 wt% of polysiloxane was added but uneven distribution when over 3 wt% of polysiloxane was added due to decreased hardness by cluster. Therefore, the addition of an appropriate amount of 2 wt% polysiloxane reinforced the porous silver with open pores to offer application for jewelry usage.

This study analyzes the effects of aging workforce on human capital and the per capita gross regional domestic product, using regional panel statistics from 1995 to 2017. According to the results of the two-stage least-squares panel regression analysis reflecting the fixed effects by region, the aging of the labor force had no effect on the human capital employment ratio and per capita gross domestic product in the metropolitan cities, but reduced human capital and per capita gross domestic product in the provinces. The share of service businesses had a positive effect on human capital in metropolitan cities, but the effect was not significant in the provinces. Human capital significantly contributed to the increase in per capita gross regional domestic product in the metropolitan cities, but the physical capital stock significantly contributed to the increase in per capita gross regional domestic product in the provinces. The results of this study suggest that the human capital job policy and the per capita regional GDP growth policy due to the aging workforce may be different between metropolitan cities and provinces.

The purpose of this study is to examine the cases of social integration in immigrants in the Netherlands and to clarify the implications for Korea. The Netherlands is a country that implements social integration policies targeting foreign immigrants. We are preemptively implementing social integration policies for foreigners ahead of us. In this study, first of all, the literature on social integration for the immigrants in the Netherlands and the consultation on the experts were sought and the implications for the Dutch government 's social integration policy were sought. In addition, policy implications were derived based on the results of Dutch case analysis. First, the social integration program of the Dutch government mandated social integration programs for migrants, and the costs were also monetized, encouraging social integration. Also, when participation in the social integration program is passive, it imposes sanctions on migrants and emphasizes the responsibility of individual migrants. In addition, the Ministry of Internal Affairs is the control tower of the government's promotion system, and it has a platform for the unity of social integration programs in local governments. Based on the results of this analysis, the implications for the social integration policy of Korea were suggested.
