Purpose - This study aimed to analyze the dynamic effects of progress in globalization on firm performance by employing individual companies' financial statement datasets. Design/methodology - The analysis leveraged the variables of operating revenue (OPRE) and pre-tax profit and loss (PLBT) as measurement variables for firm performance over 2011-2019. As a proxy variable for globalization, the trade index, a subordinate indicator of the KOF Globalization Index, was used. Through panel regression analysis, the relationship among those variables was ascertained, and the local projection (LP) method was subsequently utilized to identify dynamic effects. A subsample analysis was further performed by classifying companies based on their sizes and industries to determine the differential effects of globalization on each group. Findings - The panel regression analysis derived positive effects of an increasing degree of globalization on OPRE of Korea maritime and fishery firms. However, the impulse response functions, obtained from the LP, showed that in the short run, globalization affects PLBT negatively but in the long run, it gradually converted into a positive effect. In addition, according to the subsample analysis based on company size, the effects of globalization on OPRE became greater as each company became larger. Moreover, the industry-based analysis showed heterogeneous effects, depending on the industries in which the maritime and fishery companies operated. Originality/value - The analysis of the dynamic effects of globalization on firm performance, which revealed that the effects vary depending on the time points, is the important contribution of this study. The results also suggest that the effects of globalization vary depending on the company size and industry.

Purpose - The purpose of this study is to analyze the market power of the Korea Container Shipping Market (Intra Asia, Korea-Europe, and Korea-U.S.) to verify the existence of collusion empirically, and to answer whether the joint actions of liner market participants in Korea have formed market dominance for each route. Precisely, it will be verified through the Lerner index as to whether the regional market of Asia is a monopoly, oligopoly, or perfect competition. Design/methodology - This study used a Lerner index adjusted with elasticity presented in the New Imperial Organization (NEIO) studies. NEIO refers to a series of empirical studies that estimate parameters to judge market power from industrial data. This study uses B-L empirical models by Bresnahan (1982) and Lau (1982). In addition, NEIO research data statistically contain self-regression and stability problems as price and time series data. A dynamic model following Steen and Salvanes' Error Correction Model was used to solve this problem. Findings - The empirical results are as follows. First, λ, representing market power, is nearly zero in all three markets. Second, the Korean shipping market shows low demand elasticity on average. Nevertheless, the markup is low, a characteristic that is difficult to see in other industries. Third, the Korean shipping market generally remains close to perfect competition from 2014 to 2022, but extreme market power appears in a specific period, such as COVID-19. Fourth, there was no market power in the Intra Asia market from 2008 to 2014. Originality/value - Doubts about perfect competition in the liner market continued, but there were few empirical cases. This paper confirmed that the Korea liner market is a perfect competition market. This paper is the first to implement dynamics using ECM and recursive regression to demonstrate market power in the Korean liner market by dividing the shipping market into Deep Sea and Intra Asia separately. It is also the first to prove the most controversial problems in the current shipping industry numerically and academically.

In east Asia, the leaves of various Sasa species have been used in folk medicine for centuries. The effects of the methanolic extract and its subsequent fractions derived from the leaves of Sasa quelpaertensis Nakai on cell proliferation in human leukemia HL-60 cells were evaluated. The ethyl acetate fraction of this extract (ESQL) significantly reduced cell viability in a dose-dependent manner ($0-250\;{\mu}g/mL$). ESQL ($IC_{50}=24.8\;{\mu}g/mL$) exhibited growth inhibition comparable to the main constituent of green tea, epigallocatechin ($IC_{50}=26.2\;{\mu}g/mL$), which was used as a positive control. ESQL treatment induced apoptosis, which was confirmed by the presence of nuclear condensation and annexin V-staining. These results demonstrate that ESQL contains chemopreventive phytochemicals that may be useful in neutraceutical applications.

The purpose of this study is to develop knitwear design expressed not also Green but also LOHAS using natural yarns(wool and cotton) dyed with various natural sources(sappanwood, indigo plant, turmeric, cochineal, coffee, gallnut, and persimmon juice). This researcher tried to suggest solution scheme through the development of knitwear designs to break from the cottage industry and the limitation of design in Jeju and to preserve of traditional dye with persimmon juice simultaneously. Knitting is the formation of a fabric by the interlooping of one or more sets of yarns with hand knitting or industrial knitting. In hand-knitting, the two fundamental stitches are described as knit depending on the direction of the loop formation, front to back or back to front. In machine-knitting, the direction of loop formation is fixed, unless the stitch is mechanically transferred from front to back needle bed or vice versa. Industrial knitting technology can be divided into two main areas - weft knitting and warp knitting. Each has a different principle of construction. The majority of knitted fabrics for clothing are weft-knitted, and so this study is used weft-knitting and hand knitting technology. To achieve this purpose, researcher tried to present a lot of knitwear designs using yarns dyed with various natural sources focusing on Modern & Sophisticated Image and Elegance & Romantic Image to satisfy adult and missy consumer needs.

Purposes: Despite a lot of prior studies on psychological empowerment on positive outcomes, the objectives of this paper were to examine the role of psychological empowerment on informal learning and the mediation role of informal learning between psychological empowerment and outcome variables focused upon physical therapists working in hospital industry. Methodology: Using survey methods, the data were collected from 198 physical therapists who have worked in Ulsan city and attended in annual meeting. Findings: Results showed that psychological empowerment predicted informal learning positively but differences in mediational mechanism. Specifically, the path between psychological empowerment and proactive behavior partially mediated but no mediating effect between psychological empowerment and helping behavior. This study identified the main role of psychological empowerment on informal learning, and it expands on positive functions of the concept to learning area in organizations. The other results help advanced understanding of differential mechanism through informal learning in the process between psychological empowerment and both outcomes. Practical Implications: The current study contributes to expend the area of prior findings on psychological empowerment to learning activities implemented by individual volunteer effort. For hospitals operating the teams of physical therapy, the significance for considering psychological empowerment is highlighted as for individual growth related to job and for change behavior in the individual level.

Since public facilities have high property values and are directly exposed to the flood hazard, they account for the highest share of disaster damages compared to other assets such as housing, industry, vehicle and agriculture in case of floods. Therefore, this study was conducted to develop and suggest the potential flood damage index for public facilities to evaluate potential flood damage of specific local government directly or indirectly as a tool for decision-making related to flood prevention, maintenance, management, and budget allocation. The flood damage assessment system proposed in this study was evaluated in 231 local governments nationwide. Evaluation results showed that higher values were obtained in Seoul metropolitan government, Gyeonggi-do (province), coastal areas in Gyeongsangnam-do (province), and Jeju island.

In this study, the dyeing of Chrysanthemum indicum Linne alone and the combined dyeing of Chrysanthemum indicum Linne and onion shell were first performed to compare dyeing properties. A combination extract of Chrysanthemum indicum Linne and onion shell can be expected to improve coloration. A Hanbok design for children used a natural dyeing fashion dyeing method to make the Chrysanthemum pattern. Chrysanthemum indicum Linne is a type of wild chrysanthemum with various medicinal effects for headache and stress relief, skin diseases, insomnia and depression. Widely used onion shells have medicinal properties that help prevent and treat various adult diseases. The colors of silk dyed exclusively by Chrysanthemum indicum Linne, and the colors of silk dyed by Chrysanthemum indicum Linne and onion shell extract are yellow; in addition, silk dyed by Chrysanthemum indicum Linne and onion shell extracts were almost all unchanged. Four hanboks, which are comfortable for children to wear and use, were produced using Chrysanthemum indicum Linne and onion shell extracts. If children wear hanbok fashion products with auspicious patterns, they can provide a chance to simultaneously experience the traditional symbolism of Korean patterns and culture. In addition, it is expected to develop pride in traditional dress culture.
