The purposes of this paper are to investigate mismatch in labor supply and demand on small and medium industries in Suwon region by conducting surveys to potential employees and employers, and to suggest alternative policy means to eliminate those mismatch conditions. Reasons of occupation change, difference in terms desired in occupation between potential employee and employer, understanding in mismatch, and measure of labor shortage by firms are analyzed in this paper. The report's recommendations to eliminate labor mismatch in small and medium industry are categorized into two groups: working conditions and occupation competence. Narrowing the working conditions gap, utilization of idle workers, establishment of flexible wage system are suggested to eliminate labor condition mismatch. In addition, potential employees need to meet working requirements by building up both wide use ability, occupation specific ability, and industry specific ability.

The aims of this article is to argue that the effect of catharsis through satire and humor in Korean music, Saseolnanongga. This song is a cheerful song of four beats and the representative rap music of Korean traditional music. This song is a folk song that reveals satire and humor such as curse to the person who left me and compassion and self-absorption. The lyrics harmonize with cheerful rhythm and create laughter and the lyrics of the song itself alone cause music therapy. The contents of the lyrics of the song are already refreshing. It means that you will be able to satisfy your surrogacy through the explicit lyrics. In this way, author thinks emotional expression through singing lyrics is an alternative solution. There has been a cathartic element in many twentieth-century approaches to psychological healing. The author thinks developmental criticism leads society to health, and satirical criticism reflects and heals individuals through catharsis.

Wireless data broadcasting system that can support any number of clients is the effective alternative for the challenge of scalability in ubiquitous computing in IoT environment. In the system, it is important to evaluate quickly the performance parameter, the access time that means how quickly the client access desired data items. In this paper, we derive the mathematical model for the access time in the wireless data broadcast system adopting two-tier indexing scheme. The derived model enables to evaluate the access time without the complicated simulation. In order to evaluate the model, we compare the access time by the model with the access time by the simulation.

Chondroitin, the precursor of chondroitin sulfate, which is an important polysaccharide, has drawn significant attention due to its applications in many fields. In the present study, a heterologous biosynthesis pathway of chondroitin was designed in a GRAS (generally recognized as safe) strain C. glutamicum. CgkfoC and CgkfoA genes with host codon preference were synthesized and driven by promoter Ptac, which was confirmed as a strong promoter via GFPuv reporter assessment. In a lactate dehydrogenase (ldh) deficient host, intracellular chondroitin titer increased from 0.25 to 0.88 g/l compared with that in a wild-type host. Moreover, precursor enhancement via overexpressing precursor synthesizing gene ugdA further improved chondroitin titers to 1.09 g/l. Chondroitin production reached 1.91 g/l with the engineered strain C. glutamicum ${\Delta}L-CgCAU$ in a 5-L fed-batch fermentation with a single distribution $M_w$ of 186 kDa. This work provides an alternative, safe and novel means of producing chondroitin for industrial applications.

Relations between Ankara and Washington, which have hardly been harmonious, recently became extremely tense, especially when Turkey decided to deal with Kurdish enclaves nearby its border. Russia naturally took advantage of the tension by providing Turkey with advanced S-400 missiles and by trying to play a peacemaking role in contested regions within Syria. Ankara's dealings with Moscow alienated it from NATO and the USA, and complicated relations with Russia and its allies in Syria, where Turkey's interests collided with those of Tehran and Moscow. While these aspects of the Ankara/Moscow relationship are well known, this article explores how the discovery of natural gas in the Mediterranean has increased Ankara's importance to Moscow, as a means of sowing dissension within NATO and helping Moscow hinder the emergence of alternative gas suppliers to Europe.

The emergence of independent cinema in the United States in the 1960s was the earliest sign of postmodernism in the country, which was often referred to as "underground cinema". The works, in a counter-cultural stance, overturned the thought of depth of traditional art cinema, not exploring the meaningful relationship between form and content in terms of artistic technique, but creating an aesthetic that echoed the "Pop Art" of the time by collaging established means of expression with traditional and fashionable ones in a consumerist manner. In this paper, American independent cinema was examined, firstly by analyzing the local and external factors that contributed to its rise. Secondly, two genres of independent cinema core paradigm, "underground cinema" and "pop cinema" were focused on, as a way of demonstrating the attention and influence that independent cinema has gained. Finally, we found that independent cinemas are also seeking for alternative exploration and diverse expressions in the context of the times.

Quantification of sensitive material is of vital importance when it comes to the movement of nuclear fuel throughout its life cycle. Within the electrorefiner vessel of electrochemical separation facilities, the task of quantifying plutonium by neutron analysis is especially challenging due to it being in a constant mixture with curium. It is for this reason that current neutron multiplicity methods would prove ineffective as a safeguards measure. An alternative means of plutonium verification is investigated that utilizes the (𝛼,n) signature that comes as a result of the eutectic salt within the electrorefiner. This is done by utilizing the multiplicity variable a and breaking it down into its constituent components: spontaneous fission neutrons and (𝛼,n) yield. From there, the (𝛼,n) signature is related to the plutonium content of the fuel.

This thesis examines a significant way to enhancing and improving the term/phenomenon of performer training system in contemporary Korean theatre. To articulate the matters, this research engages in discussing and criticizing those problematic issues that we, as an instructor/trainer, have faced with through the last decades in the field of performer training and education. Specifically, we concern with the necessity of an applicable and appropriate educational/training system where each student-actor would discover his/her own adaptability by evaluating what a specific method and approach is. This atmosphere accurately provided by an instructor/trainer can also facilitate and enhance the young students' potential possibilities and/or talent, that is, as we argue a way to accomplish each performer's true nature. To achieve the goals, we underlie the necessity of establishing and/or settling performer training program/course by means of an alternative path. The research finding shows that within the atmosphere each student could share then interrogate what a possible or ideal way is according to his/her comprehensive understandings with clearer purpose: what kind of performers would you produce, train, and/or educate.

The field of extracellular vesicles (EVs) has expanded tremendously over the last decade. The role of cell-to-cell communication in neighboring or distant cells has been increasingly ascribed to EVs generated by various cells. Initially, EVs were thought to a means of cellular debris or disposal system of unwanted cellular materials that provided an alternative to autolysis in lysosomes. Intercellular exchange of information has been considered to be achieved by well-known systems such as hormones, cytokines, and nervous networks. However, most research in this field has searched for and found evidence to support paracrine or endocrine roles of EV, which inevitably leads to a new concept that EVs are synthesized to achieve their paracrine or endocrine purposes. Here, we attempted to verify the endocrine role of EV production and their contents, such as RNAs and bioactive proteins, from the regulation of biogenesis, secretion, and action mechanisms while discussing the current technical limitations. It will also be important to discuss how blood EV concentrations are regulated as if EVs are humoral endocrine machinery.
