Purpose: This study is to analyze the changes of consumption patterns to diagnose the economic impacts on consumers' market during COVID-19, and to suggest implications to overcome the new social and economic crisis of Jeju Island. Research design, data, and methodology: We collected a set of credit card transaction records issued by BC Card Company from merchants in Jeju Special Self-Governing Province for past 4 years from 2017 to 2020 from the Jeju Data Hub run by Jeju Special Self-Governing Province. The big data contains details of approved credit card transactions including the approval numbers, amount, locations and types of merchants, time and age of users, etc. The researchers summed up amount in monthly basis, transforming big data to small data to analyze the changes of consumption before and after COVID-19. Results: Sales fell sharply in transportation industries including airlines, and overall consumption by age group decreased while the decrease in consumption among the seniors was relatively small. The sales of Yeon-dong and Yongdam-dong in Jeju City also fell significantly compared to other regions. As a result of the paired t-test of all 73 samples in Jeju City, the p-value of the mean consumption of the credit card in 2019 and 2020 is significant, statistically proven that the total consumption amount in the two years is different. Conclusions: We found there are sensitive spots that can be strategically approached based on the changes in consumption patterns by industry, region, and age although most of companies and small businesses have been hit by COVID-19. It is necessary for local companies and for the government to be focusing their support on upgrading services, in order to prevent declining sales and job instability for their employees, creating strategies to retain jobs and prevent customer churn in the face of the crisis. As Jeju Province is highly dependent on the tertiary industry, including tourism, it is suggested to create various strategies to overcome the crisis of the pandemic by constantly monitoring the sales trends of local companies.

The local governments have utilized overseas offices of businesses within their jurisdiction as a forward operating base to discover and expand the overseas market. In addition, overseas offices of businesses are expected to play a big role in economic, cultural, and personal exchange, and collection of information regarding overseas market trends. Recently, inviting foreign capital, promoting cities, and attracting foreign tourists are being done through them. Since foreign capital invitation has an effect on creating jobs, the population influx, increasing local government revenues, there is a high degree of competition for it among local governments. Also, while local governments have set out to actively attract foreign tourists through city promotion marketing and developing products in connection with their region, overseas offices of businesses are playing a major role in doing the job. However, due to low performance satisfaction against the budget invested, there have been criticisms that they need to improve efficiency. As a result, each local government is faced with a task to seek efficient operational plans since overseas offices of businesses in each local government are expected to play a bigger role in trade support and international exchanges.

Purpose: The aim of this study is to identify factors of Korean female workers' childbirth plans and to establish measures to improve the childbirth plan. Methods: Study subjects were selected part in the 1st, 3rd, and 5th year surveys of the Korean Longitudinal Panel Survey of Women and Families. The selection criteria were as follows: women who had a spouse; were salaried workers currently employed for the last one month; belonged to a childbearing age; and had less than 3 children. Logistic regression analysis was conducted to investigate factors associated with childbirth plans. Results: Childbirth plans by female workers decreased each year. The analysis of associated factors revealed that age, number of children were associated factors in all years. In addition, education, satisfaction about dividing household chores with the husband, and satisfaction about working environment were associated with the lack of planning for childbirth in female workers in the 1st survey year. Satisfaction about dividing household chores with the husband, family-work conflict, and satisfaction about the potential for personal development were associated factors in the 3rd survey year. Finally, family-work conflict, satisfaction about employment stability, and satisfaction about job task at work were associated factors in the 5th survey year. Conclusion: It is important to know the measures focusing on the lack of planning for childbirth, and hence these factors can be improved by assessing in general, family, and occupational characteristics. Additionally, employer policies regarding women employees who are pregnant or have children at home need to be reviewed.

Purpose: In 2020, the franchise industry accomplished a significant growth compared to the previous year, as the number of franchise companies increased by 9.0% while the number of franchise brands increased by 12.5%. Despite growth in size, the Korean franchise industry underwent many negative incidents, such as franchise ownership sales to private equity funds, that led to deterioration of businesses. From this point of view, this study aims to make various proposals to help policy makers develop franchise industry policies by analyzing trends of the current and previous presidential administrations' franchise policies and regulations using newspaper articles. Research design, data and methodology: A total of 7,439 articles registered in Naver API from February 25, 2013 to November 29, 2021 were extracted. Among them, 34 unrelated video articles were deleted, and a total of 7,405 articles from both administrations were used for analysis. The R package was used for word frequency analysis, word clouding, word correlation analysis, and LDA (Latent Dirichlet Allocation) topic modeling. Results: The keyword frequency analysis shows that the most frequently mentioned keywords during the previous administration include 'no-brand', 'major company', 'bill', 'business field', and 'SMEs', and those mentioned during the current administration include 'industry' and 'policy'. As a result of LDA topic modeling, 9 topics such as 'global startups' and 'job creation' from the previous administration, and 10 topics such as 'franchise business' and 'distribution industry' from the current administration were derived. The results of LDAvis showed that the previous administration operated a policy based on mutual growth of large and small businesses rather than hostile regulations in the franchise business, whereas the current administration extended the regulation related to franchise business to the employment sector. Conclusions: The analysis of past two administrations' franchise policy, it can be suggested that franchisors and franchisees may complement each other in developing the Fair Transactions in Franchise Business Act and achieving balanced growth. Moreover, political support is needed for sound development of franchisors. Limitations and future research suggestions are presented at the end of this study.

Objectives: The purpose of this study is to evaluate exposure characteristics of lead using data from the domestic occupational exposure literature. Methods: Occupational airborne exposure data on lead reported in the domestic literature from 1981 to 2018 were collected and re-analyzed. The exposure levels in the data were expressed as an estimated arithmetic mean and a weighted arithmetic mean (WAM) of the number of samples. Lead exposure characteristics were analyzed by industry, process, and year. Results: From a total of 14 documents, 8,305 airborne lead measurements for 17 industries were identified, and the WAM concentration in eight industries exceeded the occupational exposure limit of 50 ㎍/m³. Three industries (battery manufacturing, lead smelting, and litharge manufacturing) accounted for 95% of the total data, and exposure trends could be confirmed over 10 years. Exposure levels continue to decrease in all three industries. Conclusions: Considering the distribution outlook of lead and lead compounds, the main management targets are lead storage battery manufacturing and secondary smelting for lead regeneration.

Objectives : The present study was performed to reveal differences between female and male cases of alopecia in their alopecia related variables such as patterns of hair loss, psychiatric characteristics, associate illnesses, and methods of treatment, and to use them as basic materials for proper management and early prevention of the alopecia prone cases. Methods : In order to analysis the gender difference in hair losses, the subjects were divided into two subgroups as the 51 cases of female alopecia and the 42 cases of male alopecia, who had visited to the department of psychiatry consulted from the department of dermatology, Yongsan hopital, ChungAng University, Seoul, Korea, from January 1998 to December 1998. In data analysis, the subjects were statistically assesed by chi-squre test and analysis of varaiance, through SPSS-$PC^+$ 9.0V. Results : 1) Female subjects were more likely showed lower socio-economical level including lower eonomical level, lower educational level, or lower occupational level in their parent's job, were more likely to have larger number of siblings and to have many sisters comparison to the male cases. 2) Female subjects were more likely visited to the department of dermatology, more history of alopecia in their female family members, lesser history of alopecia in their male family members, more loss of hairs in vertex or frontal region of scalp, lesser loss of hairs in occipital region, and lesser nail changes in comparison to the male cases. 3) Female subjects were more suffered from intra-familial conflicts and economical changes, or their introverted personality makeup, lesser likely suffered from changes of business and health changes, and showed lesser conflicts related with poorer adaptaion in their job life. 4) Female subjects were more likely diagnosed as depression or conversion disorders, more frequently complaint anxiety symptoms or depressive symptoms, higher level of anxiety index, lesser complaint somatization or obsessive compulsive symptoms, and lesser diagnosed as anxiety disorder in comparison to the male cases. 5) Female subjects were more likely tended to show personality makeup such as the introverted, the lie, the repressed, or the feminine trends than the male cases. 6) Female subjects were more significantly treated by antianxiety drug such as etizolam and dermatological therapies include tretinoin, and lesser treated by clotiazepam and prednicarbonate in comparison to the male cases. Conclusion : From the facts that The most important factors in developing hair loss in the female subjects in comparison to the male cases seems to be closely correlated with the serious psychopathology such as the presence of mental disorders including depression, the presence of complaining anxiety or depressive symptomatology, the presence of stressful life events such as intrafamilial life changes, and the presence of personality makeup such as the introverted, the lie, the repressed, or the feminine trends, the authors confirmed that dermatologists act as the primary care physician are in a unique position to recognize psychiatric comorbidity and execute meaningful intervention for female patients with the alopecia with psychiatrists.

South Korea's industrial injuries are decreasing overall in the last 32 years. Nevertheless, the fatal occupational injury rate is still higher than in developed countries. This study was conducted to help prevention strategies of occupational injuries for the Republic of Korea. Fatal occupational injury rates were obtained from "Industrial Accident Analysis"of the Korean Ministry of Labor. Poisson regression was used to assess time trends. Socioeconomic indicators were obtained from the Korea Labor Institute and the Statistics Korea. Fatal occupational injury rates were adjusted by year, and Pearson correlation analysis was used to assess the relationship between the socio-economic indicators and occupational injuries. In 1975, fatal occupational injury rate was 54.8 per 100,000 workers. With somewhat up and down, it was decreased to 21.0 in 2006. An annual rate of change for the years 1975-2006 was - 1.83%, and for the years 2002-2006 was -5.02%. As economic growth rate, paricipation rate for the age less than 25 and hours of work per week or year increased, fatal occupational injury rate also increased. Conversely, as GDP per capita, paricipation rate or employment rate for female, paricipation rate for the age 25 or more, hourly compensation costs for production workers and services output as percent of GDP increased, fatal occupational injury rate decreased. By the development of safety techniques and the adoption of more legislative constraints, developed economy reduce occupational injuries. Conversely, economic growth may raise occupational injuries. Therefore, prevention strategies are needed to manage both of them. We need to make an effort to prevent occupational injuries due to not only sexual differences, but also job differences between male and female. Preventive strategies are needed to consider the characteristics of younger workers. Addition to wage, other appropriate variables for work condition should be considered together. Extending work hours is need to be regulated with systemic methods.
