This report will use Sleep Efficiency Dataset as original data to analysis. The reason for choosing sleep pattern data for analysis is that sleep is an essential part of human beings, but nowadays people have widespread problems with sleep, especially our youngs. There are differences in people’s sleeping habits, lifestyle, and physical exercise choices, all of which can affect sleep health. Although the number of data in this dataset is not large, it is possible to analyse sleep health and its correlates from a variety of perspectives by dividing the variables into three latitudes: comprehensive sleep health indicators (sleep duration and sleep efficiency), sleep depth and lifestyle factors. Therefore, we consider the use of this dataset to be of sufficient research interest. The aim of this study is to investigate the correlation between lifestyle and sleep health, and to provide effective suggestions for improving sleep health through our findings.

This report will use 515k hotel reviews data in Europe dataseta as original data to analysis. The reason for choosing hotel review data for analysis is that hotel booking is something every traveler does. When a traveler needs to evaluate a hotel, the hotel’s scores and reviews on the booking website will largely affect the traveler’s choice of the hotel. Sentimental evaluations usually lead to more emotional choices for the traveler. Thus, in order to better understand the sentiments of reviewers when they make reviews and score evaluations, and whether those sentiments are completely due to personal factors of reviewers, 515k hotel review data in Europe are selected for analysis. And among the 218 nationalities of reviewers in this dataset, the reason for choosing the reviewers of United Kingdom nationality is that the number of reviews made by United Kingdom reviewers is in the first position in this dataset. And the gentleman temperament of the United Kingdom people has been well-known from ancient times to the present, and their attitude towards hotel reviews has certain research significance. Therefore, the choice of reviewers with United Kingdom nationality for research, firstly, there is enough samples for analysis, which makes the whole research more directional; secondly, there are enough sentimental reasons to study the correlation between the reviewing habits of United Kingdom people and their gentleman temperament.

최근 몇 년 동안 아시아에서 여성의식이 각성되기 시작했다. 여성들이 자신의 권익을 쟁취하기 시작한 가운데 한국의 페미니즘 운동은 아시아를 선도하고 있다. 여성의 지위가 높아지고 있지만 여성의 직업 문제는 항상 중요하게 여겨야 할 문제였다. 여성은 고정관념상 취약계층이고, 남성보다 월급도 훨씬 낮다. 한국복지패널이 여성층의 월소득 등 경제활동 실태를 조사한 결과 2022년 여성의 소득은 여전히 저조한 것으로 나타났다. 향후 여성의 구직과 직업복지를 더욱 발전시키기 위해서는 여성임금의 영향요인에 대한 조사가 가치가 있다고 생각한다. 이어서 한국복지패널이 2022년 17차 복지조사를 통해 여성 임금이 얼마나 되는지에 영향을 미치는 요인을 살펴보겠다.
