Much of northern Asia is lacking in high-resolution palaeoclimatic data coverage. This vast region thus represents a sizeable gap in data sets used to reconstruct hemispheric-scale temperature trends for the past millennium. To improve coverage, we present a regional-scale composite of four tree-ring width records of Siberian pine and Siberian larch from temperature-sensitive alpine timber-line sites in Mongolia. The chronologies load closely in principal components analysis (PCA) with the first eigenvector accounting for over 53% of the variance from ad 1450 to 1998. The 20-year interval from 1974 to 1993 is the highest such growth period in this composite record, and 17 of the 20 highest growth years have occurred since 1946. Thus these trees, unlike those recently described at some northern sites, do not appear to have lost their temperature sensitivity, and suggest that recent decades have been some of the warmest in the past 500 years for this region. There are, however, comparable periods of inferred, local warmth for individual sites, e.g., in 1520-1580 and 1760-1790. The percent common variance between chronologies has increased through time and is highest (66.1%) in the present century. Although there are obvious differences among the individual chronologies, this result suggests a coherent signal which we consider to be related to temperature. The PCA scores show trends which strongly resemble those seen in recent temperature reconstructions for the Northern Hemisphere, very few of which included representation from Eurasia east of the Ural Mountains. The Mongolia series therefore provides independent corroboration for these reconstructions and their indications of unusual wanning during the twentieth century.

Purpose - The purpose of this study is to analyze Trade Structure after Korea and Colombia FTA, and identify its problems and suggest measures that can be taken by the government and corporations to reinforce economic cooperation. Design/methodology/approach - To improve the level of contribution of the study, an empirical analysis is necessary. However, due to limited data access, the study will approach the topic of trade relations between Korea and Colombia with various statistics and literature. Findings - First, there is an urgent need for changes in import-export goods between Korea and Colombia, as trade is focused on specific items. Second, although foreign direct investment from Korea to the Colombia is centered in manufacturing and wholesale & retail, there should be different investment strategies by industries. Third, it is necessary to reinforce commercial cooperation. Research implications or Originality - The Free Trade Agreement between Korea and Colombia entered into force in 2016. Under the agreement, both countries will eliminated all tariffs within ten years after it takes effect. Reinforcing economic cooperation with Colombia is extremely important for Korea in terms of entering and dominating Colombian market. However, there is still a lack of research on the Colombia, and corporations that aim to enter Colombian market face difficulties due to lack of information. This study analyzes the recent trends of problems of trade between Korea and Colombia and suggests solutions for boosting trade to provide proper strategic guidelines for Korea that are planning to expand to Colombian market.

This study is to research the influence of Caesalpinia sappan which was imported through the exchanges between the Chosun dynasty and Japanese envoys during the early Chosun dynasty. Korea interchanged politically and culturally with Japan since ancient times. Particularly, the good-neighbor foreign policy toward Japan grew into trade relations. The diplomatic mission, under the name of Tongshinsa, was dispatched 12 times in total. Plenty of goods were exchanged through the visiting of Japanese envoys as well as through the activities of Korean envoys. In other words, the Korean-Japanese relations were at first focused on the political and diplomatic etiquette and gradually evolved into economic exchanges. Trading goods were various, including food, clothing, etc. Caesalpinia sappan, a red dye, was the most imported goods from Japan, but it was sold at a very high price, which caused luxurious trends in clothing. However, these sumptuous moods of the upper classes were decreased in the 16th century. Some of the reasons are : the difficulties of Japan's trade with the Caesalpinia sappan producing countries in South-east Asia, the transition of the high classes' preference from red clothing into Chinese BaecSa and SaraNeungDan, and the comparative decrease in the demand of Caesalpinia sappan by the changed understanding of Honghwa. Therefore, the early Chosun dynasty's clothing trends were due to the relationships between the Chosun dynasty and Japan.

Purpose - The purpose of this study is to examine the current trends of women in management fields from an Australian perspective. With the increase of women in the workforce, this will prove to be a valuable study. Research design, data, and methodology - This paper observed past research on women in management in Australia and defined some factors on their characteristics. Comparisons between the unique characteristics of women in management in Australia compared to those in Asia or other Western countries were evaluated. Results - Our results have showed that there are an increasing number of women in the workforce in management areas in Australia, and they are steadily rising. The gradual shift of perception in society on women entering the workplace and working will continue to have a lasting effect on the number of women in careers of management. Conclusions - The perception of women being at-home moms and men working has begun to shift in the current era. With this change evident in many countries around the world, other countries will also be able to include more women into the workplace. Raising awareness of the issues women face in the management world will be beneficial for aiding future women leaders.

The purpose of the present study was to provide an assessment of the incidence of cancer of the larynx in Kazakhstan with especial attention to ethnicity and gender, as well as age. The retrospective design covered all new cases of laryngeal cancer in 11 years (1999-2009). The total number was 4,967 cases, 4,535 (91.3%) in males and 432 (8.7%) in women, with a gender ratio of 10.5:1. Patients of Kazakh (31.2%) and Russian (51.4%) ethnicity accounted for the vast majority (82.6%), with Russians predominating in both sexes, but particularly in females. Age peak in Kazakhs was 70 years and older ($14.6{\pm}0.70/0000$), and in Russians was 60-69 years ($21.6{\pm}1.30/0000$). In the dynamics, the rates had the tendency to decrease more markedly in Russian than Kazakh men, especially in the younger groups, while increase was noted in the youngest females of both ethnicities, but again greater in Russians, presumably reflecting change in underlying lifestyle factors.

Purpose - The purpose of this study was to investigate the perception of 'unmanned cafes' on the network through big data analysis, and to identify the latest trends in rapidly changing consumer perception. Based on this, I would like to suggest that it can be used as basic data for the revitalization of unmanned cafes and differentiated marketing strategies. Design/methodology/approach - This study collected documents containing unmanned cafe keywords for about three years, and the data collected using text mining techniques were analyzed using methods such as keyword frequency analysis, centrality analysis, and keyword network analysis. Findings - First, the top 10 words with a high frequency of appearance were identified in the order of unmanned cafes, unmanned cafes, start-up, operation, coffee, time, coffee machine, franchise, and robot cafes. Second, visualization of the semantic network confirmed that the key keyword "unmanned cafe" was at the center of the keyword cluster. Research implications or Originality - Using big data to collect and analyze keywords with high web visibility, we tried to identify new issues or trends in unmanned cafe recognition, which consists of keywords related to start-ups, mainly deals with topics related to start-ups when unmanned cafes are mentioned on the network.

Purpose - The purpose of this study was to investigate consistency in estimating the number of vacant jobs using the two business labor force survey with two different time points of survey. Design/methodology/approach - We studied the cause of the differences in estimating the number of vacant jobs between the monthly sample and the new sample in business labor force survey. Findings - To summarize our findings, As the size of the company increases, the number of vacant jobs in the company also increases, and the probability that the number of vacant jobs in the company is zero decreases. The monthly sample was assessed to have a higher likelihood that the number of vacant jobs in the company was zero and the number of vacant jobs was considerable compared to the local sample. Research implications or Originality - Because local survey sample companies tend to minimize the number of vacant jobs even when they reply under the same conditions, the estimation result of the number of vacant jobs in the current monthly survey differs significantly from the estimation result of the local survey. Divergent "degrees of knowledge of question items," survey methodologies, or investigators could be the causes of the various response trends.

Purpose - This study attempted to analyze news big data in order to examine the trend of change in housework due to technological innovation and family changes. Research design, data, and methodology - News big data was collected from Bigkinds for the purpose of trend analysis. A total of 8,270 articles containing 'housework' were extracted from news articles between January 1, 1990 and December 31, 2021. 11 general daily newspapers and 8 business newspapers were selected and were analyzed by dividing them into five-year units. Result - The change of trends in housework that appeared through news big data analysis can be summarized as below. First, the tendency to regard housework as work of women or housewives is gradually weakening. Instead, the centrality of connection with double income is increasing. Second, there is a tendency to strengthen the institutional approach to evaluation of the productivity of housework. Third, the possibility of market substitution for housework is expanding. Conclusion - In the era of the 4th industrial revolution, examining the impact of technological innovation and family change on housework not only enables the prospect of an industry, but also provides implications for policies related to housework. In addition, this study is differentiated in that it contributed to expand the field of housework research previously limited to analyzing survey data.
