In the paper of 'Natural Selection Favors AIs over Humans,' Dan Hendrycks applies principles of Darwinian evolution to forecast potential trajectories of AI development. He proposes that competitive pressures within corporate and military realms could lead to AI replacing human roles and exhibiting self-interested behaviors. However, such claims carry the risk of oversimplifying the complex issues of competition and natural selection without clear criteria for judging whether AI is selfish or altruistic, necessitating a more in-depth analysis and critique. Other studies, such as ''The Threat of AI and Our Response: The AI Charter of Ethics in South Korea,' offer diverse opinions on the natural selection of artificial intelligence, examining major threats that may arise from AI, including AI's value judgment and malicious use, and emphasizing the need for immediate discussions on social solutions. Such contemplation is not merely a technical issue but also significant from an ethical standpoint, requiring thoughtful consideration of how the development of AI harmonizes with human welfare and values. It is also essential to emphasize the importance of cooperation between artificial intelligence and humans. Hendrycks's work, while speculative, is supported by historical observations of inevitable evolution given the right conditions, and it prompts deep contemplation of these issues, setting the stage for future research focused on AI safety, regulation, and ethical considerations.

Purpose - This research aims to investigate the effects that the selection of oriental medicine cosmetics and brand asset attributes have on consumers' economic, emotional and social values in order to shed light on the forms and characteristics of consumption within the globally developing oriental medicine cosmetics market, and in the end positively verify how such perceived values affect purchase intention. In addition, it proposes research outcomes by comparing the differences between national and cultural consumer purchase behavior based on the comparisons of consumer groups in South Korea and China, the major markets for oriental medicine cosmetics. Research design, data, and methodology - Based on advanced research a total of 9 hypotheses were designed and questionnaires consisting of 16 questions to identify six major variables were conducted. Research was carried out centered on Seoul, South Korea, and its surrounding metropolitan area as well as Beijing and Shanghai, China, and a total of 577 sets of significant data were collected. A comparison analysis was then conducted on the data from 285 Koreans and 292 Chinese. A regression analysis and path analysis were also carried out based on a structural equation model to suggest results. Results - Research results show brand value assets had a more crucial impact on consumers' perceived value than consumer selection of oriental medicine cosmetics, while emotional value had a bigger effect on purchase intension than social or economic values. For Chinese consumers in particular, social, economic and emotional values affected purchase intention, while emotional value was the most crucial factor for Korean consumers. Conclusions - With oriental medicine cosmetics, brand characteristics and images that helped express emotional desire proved to be more effective in marketing than the performance aspect of cosmetics, including their functions and ingredients. In the end, products that highlight individual desire and emotion should be introduced instead of those that emphasize price, functions and social characteristics in order to expand the global market of oriental medicine cosmetics.

본 연구에서는 한국노동연구원의 "2015년 한국노동패널조사 (KLIPS)" 자료를 활용하여 국내 여성의 임금 결정요인을 분석하기 한다. 일반적으로 임금 자료는 랜덤 추출이 불가능하기 때문에 분석하기가 쉽지 않다. 표본 선택 편의 (sampling bias)가 있는 자료를 분석하는 방법으로 Heckman 표본 선택 모형이 가장 널리 알려져 있다. Heckman은 크게 두 가지 모형을 제안했는데, 그 중 하나는 최대 우도 방법을 이용하는 것이고, 다른 하나는 2단계 표본 선택 모형이다. 이 중 Heckman 2단계 표본 선택 모형은 주된 결과 모형 (outcome model)과 경제 활동 여부를 결정짓는 선택 모형 (selection model)을 포함한 모형으로써, 이 모형이 최대 우도 방법을 이용한 모형에 비해 이변수 오차의 정규분포 가정에 덜 민감하다고 알려져 있다. 그럼에도 불구하고 이변수 오차에 대한 정규 분포 가정은 꽤 강한 가정이라고 볼 수 있는데, 최근에 이 모형의 단점을 보완하는 모형으로 Marchenko와 Genton (2012)의Heckman 표본 선택 t 모형이 제시되었다. Heckman 2단계 모형과 Heckman 표본 선택 t 모형을 이용하여 국내 여성의 임금 결정 요인을 분석하고 비교하도록 한다.

본 연구에서는 한국고용정보원에서 실시한 "2013 고졸자 취업진로조사" 자료를 활용하여 특성화고 졸업자의 임금결정요인을 분석하였다. 일반적으로 임금은 개인의 취업여부와 임금의 크기에 대한 두 가지의 복합적인 정보를 담고 있다. 그러나 임금 결정요인분석의 많은 선행연구에서는 후자의 정보만을 대상으로 최소제곱법에 기초한 선형 회귀분석을 수행함으로써 표본선택에 의한 편의 (sample selection bias) 문제가 발생하게 된다. 본 연구에서는 임금결정요인분석에서 표본선택에 의한 편의 문제를 극복하기 위해 Tobit 모형과 Heckman의 표본선택 모형을 분석에 활용하였다. 주요 분석 결과를 요약하면 다음과 같다. 먼저 Tobit 모형과 Heckman의 표본선택 모형에 대한 타당성은 통계적으로 유의함을 알 수 있었다. 성별은 취업확률과 임금의 크기에서 모두 통계적으로 유의한 것으로 나타났다. 마이스터고 졸업생은 취업확률과 임금의 크기 모두 기타고 졸업생에 비해서 높은 것을 알 수 있었으며, 부모소득이 높을수록 취업확률과 임금의 크기가 모두 통계적으로 유의하게 증가하였다. 부모학력이 고졸이하에 비해서 대졸이상이 취업확률은 통계적으로 유의하게 낮지만, 임금의 크기는 높게 나타났다. 고교성적은 높을수록, 고교 만족도가 높을수록, 그리고 자격증 수가 많을수록 취업확률과 임금의 크기 모두 통계적으로 유의하게 높은 것을 알 수 있다.

Objectives: The purpose of this study was to investigate influences on employment preparation in dental hygiene students. Methods: A self-reported questionnaire was completed by 386 dental hygiene students in South Korea from November 1 to 30, 2016. For data analysis, the study used independent t-tests, one-way analysis of variance, Pearson correlation analysis, and regression analysis among others. Results: Students with higher grades tended to have major satisfaction, instruction participation, and employment preparation (P<0.001). Higher parental monthly income was related to higher major satisfaction (P<0.001). Employment preparation was significantly positively related to major selection motive, major satisfaction, and instruction participation. Conclusions: In order to encourage dental hygiene students to prepare for employment, it is necessary to create a better academic environment and develop a variety of employment preparation education programs. I think that the active interest of the country, society, school, and family will have a positive impact on employment preparation.
