BACKGROUND/OBJECTIVES: The economic recession caused by the coronavirus disease 2019 pandemic disproportionately affected poor and vulnerable populations globally. Better uunderstanding of vulnerability to shocks in food supply and demand in the Asia Pacific region is needed. SUBJECTS/METHODS: Using secondary data from rapid assessment surveys during the pandemic response (n = 10,420 in mid-2020; n = 6,004 in mid-2021) in India, Indonesia, Myanmar, and Vietnam, this study examined the risk factors for reported income reduction or job loss in mid-2021 and the temporal trend in food security status (household food availability, and market availability and affordability of essential items) from mid-2020 to mid-2021. RESULTS: The proportion of job loss/reduced household income was highest in India (60.4%) and lowest in Indonesia (39.0%). Urban residence (odds ratio [OR] range, 2.20-4.11; countries with significant results only), female respondents (OR range, 1.40-1.69), engagement in daily waged labor (OR range, 1.54-1.68), and running a small trade/business (OR range, 1.66-2.71) were significantly associated with income reduction or job loss in three out of 4 countries (all P < 0.05). Food stock availability increased significantly in 2021 compared to 2020 in all four countries (OR range, 1.91-4.45) (all P < 0.05). Availability of all essential items at markets increased in India (OR range, 1.45-3.99) but decreased for basic foods, hygiene items, and medicine in Vietnam (OR range, 0.81-0.86) in 2021 compared to 2020 (all P < 0.05). In 2021, the affordability of all essential items significantly improved in India (OR range, 1.18-3.49) while the affordability of rent, health care, and loans deteriorated in Indonesia (OR range, 0.23-0.71) when compared to 2020 (all P < 0.05). CONCLUSIONS: Long-term social protection programs need to be carefully designed and implemented to address food insecurity among vulnerable groups, considering each country's market conditions, consumer food purchasing behaviors, and financial support capacity.
Since inaccurate demand estimation for recent urban rail construction may result in financial burden to cities, precise prediction for operating cost as well as construction costs is necessary to avoid or reduce budget loss of the local or central government. The operating cost is directly related to the public fare and affect a policy to determine the rate system. Therefore, there is a pressing need to develop an estimating model for reliable operating cost of urban railway. This study introduces a new model to estimate the operating cost with new variables. It provides a better prediction in accuracy and reliability compared to the existing model, considering the feature of urban railway. For verification of our model, railway operation data from a few cities for the last five years were comprehensively examined to determine variables that affect the operating cost. The operating cost was estimated in a dummy regression model using five independent variables, which were average distance between stations, daily trains distance, total passenger capacity of a train in a train, driving mode(manned/unmanned), and investment type(financial/private).

This study examines the unemployment and labor market demand dynamics as well as their implication for social exclusion in the metropolitan areas of Korea since the financial crisis of 1997. The unemployment research containing significant implication for social exclusion is a key area to be explored with the research of skill and income polarization due to structural economic transformation. Skill polarization usually results in the job loss for some people, which most likely leads to the economic deprivation and social exclusion. The unemployment rate and its regional disparity began to fall since 2000, but the disparity reversed to increase after 2005. The labor market dynamics of the metropolitan areas are turned out to be related with the size of the city and the relative shares of both manufacturing and service sectors. In addition, the employment growth is turned out to be related with the changes of both output and productivity. It is also found that the unemployment is affected with the job change and the tertiarization of the economy. However, it is of more significance to recognize that the dynamics and patterns of the labor market in the metropolitan areas are quite spatially differentiated and the differentiation is likely determined by the factors such as industrial structure, employment dynamics and job demand changes.
An increase in damage to crops and facilities caused by wildlife such as wild boar causes serious social and economic problems to the rural economy in Korea. This study aims to estimate the economic losses incurred to rural households in mountain villages near protected areas in Korea due to the damage to agricultural and forestry production by wildlife. The case of mountain villages located in Toji-myeon, Gurye-gun near the Jirisan National Park was studied as an example. Data were collected by interviewing 84 households across six mountain villages in April and June 2016. The results indicate that the economic losses due to wildlife damage in 2015 were estimated to be 1.65 million KRW per household, which is a total of 138.63 million KRW for the 84 households. Among local products, the most damaged products were chestnut, fern-brake, wild pear, peach, and potato, whereas the most damaged products per production area were sweet potato, peach, corn, and potato. The potential economic losses caused by wildlife damage to agricultural and forestry production in whole Gurye-gun area was estimated to be around 4.0 billion KRW in 2015. However, the municipal government budget for the compensation of wildlife damage was only 0.9 percent of the potential rural economic losses caused by wildlife damage in 2015. The results of our study suggest that the compensation scheme for wildlife damage is inadequate in the respect of social justice. Considering the low financial capacity of the municipalities in mountain areas, the central government should take a progressive responsibility by allocating more financial resources for compensation of economic losses of rural households due to wildlife damage. The equitable and effective governance of wildlife conservation is required for sustainable development of rural communities near protected areas.
Earnings management is defined as an intentional act during the financial reporting process or a manager's choice of accounting policies to avoid earnings decreases or obtain some private gains. Shipping firms have a highly debt-intensive capital structure and a significant motivation in earnings management to avoid failure of a Debt Covenant. From this point of views, this paper tries to determine the relationship between the capital structure and discretionary accruals estimated using the re-modified Jones model (1995). The sample used to test the research models is made up of 87 Korean shipping firms during the period from 2007 to 2015. A histogram analysis, t-test and FGLS confirm the possibility of using earnings management, and it proved that Korean shipping firms manage their earnings to avoid financial loss. An analysis of the relationship between the capital structure and earning managements, shows it is difficult to support the Debt Covenant, shown as a negative relationship between the debt ratio and debt maturity as shipping firms' capital structure and discretionary accruals as earning management variable. An additional analysis presents a negative relationship between previous debt maturity and discretionary accruals, and the possibility of earning management in a highly increased debt ration group.

This study is an experiential case study of cybercrime fraud that combines pharming and voice phishing in April 2017. Research on victims who have actually suffered in the study of crime or disaster is a very useful field in establishing crime prevention measures. This study is significant in that Korea is relatively poor in this kind of research. I got cyber fraud as a consequence of my loss of reasonable judgment due to mental confusion when a companion dog who was raised for 8 years was in a very dangerous situation with cystitis. Fortunately, I received all the damages in a quick report, but the period was eight months. It took too much time to get back all the damages, so I had to suffer another pain. Based on my experience, I suggest damage prevention measures. First, when a certain condition and a certain amount are transferred, the transaction is automatically stopped or a more strict confirmation procedure is added. Secondly, trafficking means to arrest the perpetrator without any harm to the victim is sought. Third, the victims of crime should be promptly reimbursed for damages or a system for lending their living funds to zero or lower interest rate.

This study analyzes the effects of freight transportation income, capital, asset, non-operating expenses, and debt ratio on the debts of inner port freight transportation businesses through the GLS of panel regression analysis and the estimation of fixed effects model. The factors and hypotheses were established through a theoretical background review, and the financial statement and profit and loss data of inner port freight transportation businesses for 10 years from 2006 to 2015 were analyzed. The results showed that assets had positive effects on debts, and negative effects on capital, non-operating expenses, and debt ratio, but no effect on freight transportation income. This result empirically demonstrates the tendency of inner port freight transportation businesses to secure assets by increasing debts, creation of debt reduction leverage effect using non-operating expenses such as interest expenses through bank borrowing, and the adoption of management characteristics and financial operation method to lower the debt ratio by reducing capital more than debts. In future studies, it is necessary to analyze coastal port freight transportation business by industry (oil tankers, cargo ships, and barge ships), and regions such as East, West and South sea.
Purpose - This study seeks to investigate the determinants of global sourcing intention in clothing sewing industry, in particular with its focus on women's knit wear production. Design/methodology/approach - This study collected a unique set of qualitative data through 31 in-depth interviews with fashion brands, promotion agencies, and sewing factories between July 2023 and October 2023. In addition, it analyzed the dataset using the MAXQDA to complement the research findings. Findings - We have two findings. First, the interviewees commonly mentioned the following factors as reasons for considering global sourcing: the human factors(aging of skilled technicians and labor shortages), the financial factors(gap in production unit prices at home and abroad), the relational factors(lack of novelty), and the physical factors(loss of production infrastructure and network), while the human factors(skilled workforce), the production factors(delivery date and product quality), and the relational factors(timely communication and mutual trust) as reasons for continuing domestic sourcing. Additional code analysis of interview also supports this finding. On the other hand, there was also a subtle difference between buyers(brands) and suppliers(promotion agencies and processing plants), and buyers consider the exact delivery date critical so that they could see trend-sensitive women's knit wear on time, and suppliers took production costs, labor costs, and labor shortages, which are financial factors, more seriously. Research implications or Originality - This study provides a richer and more balanced view of existing literature, which has generally tended to introduce global sourcing across the clothing industry despite the existence of various diversity within the industry. In addition, through qualitative research, we introduce that the sewing industry is carried out according to complex factors, and by revealing and categorizing the determinants of global sourcing, we supplement the existing research on the clothing sewing industry centered on survey. On a practical note, this study introduces that there is a difference in view of domestic sourcing and global sourcing between buyers(brands) and suppliers(promotion agencies and sewing factories), suggesting practical implications for revitalizing networks and deriving win-win cooperation network models among members in the future.
The purpose of this study was to present basic data in the nursing practice for the management of living kidney donor by understanding the nature and meaning of kidney donors, experiences. The research subjects were 11 living kidney donors who had donated from Mar 1991 to Feb. 1994 and discharged from the 3 hospitals in Pusan. Data has been collected by Intensive interview with donors. The data analysis has made by phenomenological method of Van Kaam for understanding the phenomenon and meaning of their experiences. The experiences of kidney donors were analyzed into the 4 situations, that is,'motivation of kidney donor', 'decision time to make kidney donation', 'pre-opperation','after donation'. The descriptive expression and common elements were drawn from original data of each situation on the basis of subjects' own words. From each situation, the com-mon elements of kidney donors' experiences were integrated, summarized and described as follows 1. Motivation of kidney donation They wanted to donate their kidney because of empathy of pain on the groung of love to the recipient and with exppectation of successful kidney transplant or as a solution of economic difficulty. 2. Experiences in deciding to make kidney do-nation In deciding to make kidney donation, donors had love toward the recipients. But they experienced conflict too. 3. Experiences before being operated on donated kidney In experiences from deciding to make kidney do nation to preoperation, donors had love toward the recipients. But they also felt anxiety or dissatisfaction. Therefore, they controlled their mind by their faith, support of medical staff or support of society. And they experienced regret for the sociological cognition or financial apprehension. 4. Experiences after kidney donation After kidney donation, donors experienced satis-faction and accompplishment in spite of mental and physical discomfortness, while they felt sense of loss / disappointment, repentance, regret, and apprehension of progress toward their condition. Thus, kidney donors donated their kidney on the ground of empathy and love to the recipient and with expectation of successful kidney transplant. But during the process of kidney donation, they ex perienced conflict, love, anxiety, regret, apprehension of economy. And after donation, they felt sense of satisfaction and accomplishment, while they felt sense of discomfortness, loss / disappointment, re-gret, repentance, or apprehension of progress toward their condition. This result contribute to nurses' role not only for the management of living kidney donors but also for the management of cadaver donors' family.

Unmanned Aerial Vehicles (UAV) that are piloted without human pilots can be commanded remotely via frequencies or perform pre-inputted missions. UAVs have been mainly used for military purposes, but due to the development of ICT technology, they are now widely used in the private sector. Teal Group's 2014 World UAV Forecast predicts that the UAV market will grow by 10% annually over the next decade, reaching $ 12.5 billion by 2023. However, because UAVs are primarily remotely controlled, if a malicious user accesses a remotely controlled UAV, it could seriously infringe privacy and cause financial loss or even loss of life. To solve this problem, a secure channel must be established through mutual authentication between the UAV and the control center. However, existing security techniques require a lot of computing resources and power, and because communication distances, infrastructure, and data flow are different from UAV networks, it is unsuitable for application in UAV environments. To resolve this problem, the study presents a lightweight UAV authentication method based on Physical Unclonable Functions (PUFs) that requires less computing resources in the ground Control and Non-Payload Communication (CNPC) environment, where recently, technology standardization is actively under progress.
