박희주(Hee Joo Park),류지훈(Ji Hoon Ryoo) 한국교육평가학회 2023 교육평가연구 Vol.36 No.2
종단연구에서 성장모형을 탐색하는 것은, 성장과 관계된 변인의 효과성을 검증하는 것만큼 중요하다. 본 연구는 성장모형을 확인함에 있어 종단연구에서 일반화 가법 혼합 모형(GAMM)과 조각별 성장모형(PGM)을 활용하여 분석을 진행하였다. 실증자료는 한국교육종단연구(KELS-2013) 데이터를 통해, 학생들의 수학 학업성취도의 변화를 GAMM과 PGM을 활용하였다. 연구 결과, 첫째, GAMM에서 최적화된 성장모형 함수의 지수가 2.98로 산출되어, 성장모형은 3차 함수에 가장 적합한 것을 확인하였다. 또한 GAMM을 적용해 무선 효과를 검증한 결과, 조사의 시작점인 1차년도에서 198.73점의 성장을 확인하였고, 학생들의 수학 학업성취도 성장에 있어서는 여학생이 남학생보다 2.97점 높은 성장을 보이는 것을 확인하였다. 둘째, PGM을 적용한 결과, 전환점은 2.54에서 나타나 초등학교에서 중학교로 학교 급이 변화하는 시점에서 가장 큰 변화를 보이는 것을 확인하였다. 본 연구의 결과는 데이터 기반 성장모형을 탐색하는 GAMM과 PGM을 통한 접근을 시도했으며, 이러한 연구는 데이터 기반 기계학습법 등의 성장모형 분석으로 크게 확장될 수 있다. Exploring a growth model in a longitudinal study is as important as verifying the effectiveness of variables related to growth. In this study, in identifying the growth model, the analysis was conducted using the generalized additive mixed model (GAMM) and the piecewise growth model (PGM) in longitudinal study. For empirical data, GAMM and PGM were used for identifying changes in students' academic achievement in mathematics through the Korean Education Longitudinal Study (KELS-2013) data. As a result, the exponent of the growth model function optimized in GAMM was calculated as 2.98, confirming that the growth model was most suitable for a cubic function. In addition, as a result of verifying the random effect by applying GAMM, a growth of 198.73 points was confirmed in the first year, the starting point of the survey, and it was confirmed that female students showed 2.97 points higher growth than male students in terms of growth in students' math achievement. On the other hand, as a result of applying PGM, the turning point appeared at 2.54, and it was confirmed that the greatest change was shown at the time of school grade change from elementary school to middle school. Such results as in this study show different approaches through GAMM and PGM to explore data-based growth models, and these results can be greatly expanded to analyze growth models such as data-based machine learning methods.

박희주(PARK Hee-Joo) 한국생명윤리학회 2002 생명윤리 Vol.3 No.1
This study documents cloning controversies in S. Korea. The development of Korean episodes divide into three periods. First, the news from Scotland in the early 1997 ignited the cloning controversy in Korea. The technology that gave birth to Dolly could be used for human cloning. This possibility touched the ethical nerve cord of the many religionists and philosophers in Korea. This was, however, a mere reaction of Korean society to a scientific breakthrough made in a foreign country. In the second period, cloning became a national issue of her own when some Korean scientists successfully developed their own cloning technology. For instance, Hwang Woo Suk, professor of veterinary science at Seoul National University, cloned a cow in 12 February 1999, that was the world's fifth success in animal cloning. This produced mixed responses of national pride and horror. In the third period, the focus of cloning controversy shifted to the therapeutic cloning. If the ethical concern on human cloning dominated the first and second period, medical and economical concerns were strongly expressed by the supporters of this new technology. Therapeutic cloning used cloned human embryo from which stem cells were extracted. This process inevitably involves destruction of the human embryo, that raised serious ethical concern. Therefore, an alternative method was developed to avoid such an ethical hurdle, that used adult somatic cells as a source for stem cells. Now the relative merits of these methods in terms of medical, economical and ethical concerns are weighed and this consists of the core of the present disputes over therapeutic cloning.

WSN 상에서 비연결성을 제공하는 효율적인 사용자 인증 기법에 대한 보안 고찰
박희주(Hee-Joo Park),김현성(Hyunsung Kim) 대한전자공학회 2015 대한전자공학회 학술대회 Vol.2015 No.6
Jiang et al. proposed an efficient authentication scheme for unlinkability for wireless sensor networks (WSNs). This paper reviews Jiang et al.‘s authentication scheme and provides security concerns focused on some weaknesses and flaws. It is weak against verification table attack and desynchronization attack. Furthermore, it requires to use synchronized time over the WSN and has flaw in the password update phase.

박희주(Park, Hee-Joo) 창조론오픈포럼 2008 창조론오픈포럼 Vol.2 No.1
In this paper, I propose dialogue between various Christian positions on the question of origins; young-earth creationism, old-earth creationism, intelligent design theory, and theistic evolutionism. Although they differ in answering the question of "how and when" the Creator created this universe, they all agree in the question of "who" created the universe. Among these three vital questions I argue the "who" question has the utmost importance and the "how and when" should be subordinate to it. As various Christian positions conflict each other at present due to their differences in answering "how and when" questions, I propose that focusing on "who" rather than "how and when" will open the door for dialogue.

박희주 ( Hee Joo Park ) 기독교학문연구회 2007 신앙과 학문 Vol.12 No.2
1980년대 초 미국의 창조론이 국내에 상륙한 이후 창조-진화 논쟁에 대한 관심이 고조되었으나 그 역사적 뿌리와 쟁점에 대한 체계적인 논의는 부족하다. 이를 위해 이 논문에서는 20세기의 대표적 진화론 논쟁인 미국의 스코프스 재판을 소개한다. 먼저 이 논쟁의 배경으로 미국사회에 진화론이 도입되고 반진화론 운동이 전개되는 과정을 간략하게 설명한다. 특히 1920년대 들어 갑자기 보수 기독교인을 중심으로 반 진화론적 정서가 퍼져나가는 과정을 설명했다. 이어 스코프스 재판을 통해 반진화론운동의 선봉장인 정치가 브라이언과 진보적 세계관을 대표하는 다로우가 격돌하는 과정을 살펴볼 것이다. 마지막으로 결론에서 스코프스 재판이 진화론교육과 반진화론운동에 끼친 영향을 살펴보았다. 이 논문에서 결론은 스코프스 재판은 기독교 근본주의와 진화론 교육에 모두 타격을 입혔고 진화론 논쟁은 향후 30년간 소강상태에 빠져들며 이로써 20세기 진화론 논쟁의 한 막이 내리게 된 것이라는 주장을 한다. In this paper, I will deal with the Scopes Trial that was the most prominent creation-evolution controversy in the twentieth century. Firstly, I will describe how Darwin``s theory of evolution was introduced to the U.S. and how anti-evolution movement was mobilized. In particular, I will explain how the anti-evolution sentiment abruptly surged within the conservative Christian circle in the early 1920s and how evolution became a controversial social issue. Then I will describe the sweeping anti-evolution movement and, in particular, the passage of the anti-evolution law in Tennessee which resulted the Scopes Trial. During the Trial, the focal point was the confrontation between Bryan who led the anti-evolution crusade and Darrow who represented the evolution side. Lastly, I will examine the impact of the Scopes Trial on the anti-evolution movement and evolution education.
