  • 이 연구에서는 플로지스톤설에서 산소설로의 개념변화 과정에서 제시된 변칙 사례와 대안 가설에 대한 학생들의 반응을 조사하고, 이를 과학자들의 반응과 비교했다. 변칙 사례와 대안 가설에 대한 과학자들의 반응은 과학사 관련 문헌에서 수집했다. 선개념 검사를 실시하여 연소에 대한 목표 오개념을 지닌 중학교 2학년 학생 148명을 선발했다. 학생들에게 변칙 사례와 대안 가설을 제시하고, 이에 대한 학생들의 반응을 조사했다. 연구 결과, 과학자들과 학생들에게서 유사한 반응 유형이 나타났지만, 동시에 명확한 차이점도 있었다. 과학자들은 변칙 사례의 문제점을 밝히고자 노력하는 경향이 있었지만, 학생들은 자신들의 초기이론에 대한 신념을 고수하기 위해 변칙 사례를 거부하거나 배제하는 경향이 있었다. 또한, 대안 가설을 접한 후에 자신의 신념을 바꾸는 학생은 일부에 불과했다.

  • Traditional Asian medicine has an extensive evidence base built upon thousands of years of experience within Asia, of curing various diseases. Only recently, within the past two centuries, have modern medical scientists developed interest in traditional Asian medicine. Asian Medicine seems to be regarded only as an adjunctive medicine and viewed as alargely un-proven alternative medicine to complement western medicine, used in some cases to establish a new paradigm of "integrative medicine". This article reviews how Korean herbal cosmetics emerged by applying traditional Asian medicine to the science of cosmetics. The characteristics of Korean herbal cosmetics are examined through examples of history, concepts and traditions. With the advancements in biotechnology, studies are now being conducted on the dermatological effects and processing methods of herbal ingredients, including ginseng. The authors explain the current research on the identification on the active ingredients of herbs, extraction methods, and bio-processing of ingredients to improve the biological efficacies of herbs on the skin. A summary of studies focused on modern reinterpretations of ageing theories, such as 'Seven year aging cycle', are provided. In conclusion, the development of Korean cosmetics products are based on the accumulated knowledge of thousands of years of experience including; 1) practical heritage of traditional Asian medicines such as Donguibogam; 2) excellent medicinal plants, such as ginseng, which are native to Korea; and 3) innovative attempts to modernize materials, processes, and principles.

한국디자인사 연구의 문화사적 접근을 향하여 -양갑조 할머니의 규방 공예품을 위한 변론- (Toward the Cultural Approach to the Discipline of Korean Design History: -A Plea for the Domestic Handcrafts of Yang, Gap-Jo-)

  • 한국 디자인사의 일반적 접근 경향은 한국의 정치, 경제, 사회적 측면에서 근대화 문제와 관련된 거대 담론에 주로 연구 초점을 맞추어 왔다. 근대화 논의에는, 그러나, 자본주의적 생산양식의 자장 안에서 전개되는 공적, 제도적, 권력적 근대화 외에 일상적인 삶의 양식으로 발현되는 사적, 개인적, 문화적 근대화라는 두 측면이 내재되어 있다. 특히, 현실사회주의의 실패 이후 후자의 관점이 역사학계를 비롯한 제 분야에서 새로운 대안으로 부각되고 있음에도 불구하고, 한국 디자인 역사 연구가들의 근대적 디자인 현상에 대한 역사 인식은 일상적 현실 안에 존재하는 ‘아래로부터의 역사’이기보다는 현실 밖에 담론의 차원으로 존재하는 ‘위로부터의 역사’인 경우가 많았다. 이와 같은 엘리트 중심의 역사인식 틀에 균형감을 부여하기 위해서는 보통 사람들의 자발적인 디자인 행위로 구현된 일상적 삶의 표상들을 연구대상으로 삼음으로써 한국 디자인의 역사를 일상 문화적인 시각을 통해 아래로부터 재구성하는 작업이 요구된다. 이 물음에 대한 한 가지 접근방법은 지순한 한국 어머니 상의 전형인 올해 87세의 양갑조 할머니가 일생동안 제작해 온 규방 공예품을 문화사적 시각으로 읽어내는 일이다. 한국 디자인사의 거시적 담론 속에 묻혀버린 민초들의 일사적인 삶의 구적들에 대한 역사적 반추 작업을 통해 작지만 다층적인 한국 디자인의 의미소들을 발굴해 냄으로써 문화사로서의 한국 디자인의 역사적 전망을 가늠해 보는 전기를 마련하고자 한다.

  • In a short history, RNA-seq data have established a revolutionary tool to directly decode various scenarios occurring on whole genome-wide expression profiles in regards with differential expression at gene, transcript, isoform, and exon specific quantification, genetic and genomic mutations, and etc. RNA-seq technique has been rapidly replacing arrays with seq-based platform experimental settings by revealing a couple of advantages such as identification of alternative splicing and allelic specific expression. The remarkable characteristics of high-throughput large-scale expression profile in RNA-seq are lied on expression levels of read counts, structure of correlated samples and genes, larger number of genes compared to sample size, different sampling rates, inevitable systematic RNA-seq biases, and etc. In this study, we will comprehensively review how robust Bayesian and non-parametric methods have a better performance than classical statistical approaches by explicitly incorporating such intrinsic RNA-seq specific features with flexible and more appropriate assumptions and distributions in practice.

  • Breast cancer is the most common cancer in females all over the world with approximately one million new cases each year as well as one of second leading causes of death among females. In Pakistan, the most frequently diagnosed cancer among females is also breast cancer, accounting for nearly one in nine female patients. Its incidence in Pakistan is 2.5 times higher than that in neighboring countries like Iran and India. The risk factors associated with breast cancer are age, family history, early menarche, intake of combined estrogen and progestin menopausal hormones, alcohol consumption, physical inactivity, low socioeconomic status and lack of awareness regarding the disease. This mini-review article aims to provide awareness about breast cancer as well as an updated knowledge about the prevalence, risk factors and disease knowledge of breast cancer in Pakistan.

  • The medicines for treating osteoporosis currently in use have minor to severe side effects, and can be financially burdensome. Thus, there is a need for prevention and alternative supplement that is relatively inexpensive, and can be easily consumed daily as an alternative dietary therapy. In this study, bone marrow density of the spine and femur of osteoporosis patients were checked before and after consuming complex composed of calcium and magnesium, considered to be the core of bone mineral content. November 2017-November 2021, patients with T-score of less than -2.5 or -1.0 < T-score < -2.5 with history of fractures or recent fractures were enrolled. The data of 60 patients who orally administered Ionized Cal/MagTM Complex were reviewed retrospectively, and it was significantly confirmed that the average value of T-score was up-regulated by 0.5. Additionally, the cumulative dose was observed to have a positive effect, on the improvement of BMD in the 2nd Lumbar and Femur neck. It is expected that better results will be achieved if use of the supplement is continued.

  • In this study, we investigate integrated educations as an alternative educational method. I look around the developments of the integrated educations from MST education through STEAM education, especially in mathematics education. I analyzed integrated educations such as MST, STS, STEM, STEAM educations and compare them to each other, in mathematics education. And I discuss how to apply STEAM education to Korean mathematics education. I suggest a proper integrated education, in particular, STEAM education, as one that is suitable for Korean mathematics education.

  • The registration of Dongeuibogam as UNESCO's Memory of world was not only a national triumph but also an internationally important event. This event got rid of the opinions that suggested Dongeuibogam was a medical system practiced only un the limited area of Korea and this event signified the restoration of Dongeuibogam's international and universal position. Therefore, ih is now our job to find Dongeuibogam's modern applications and restore its value. This study was carried out with the purpose of examining the significance of Dongeuibogam's registration as Memory of world from a medical history's point of view and finding its modern applications. The author discussed significance in three parts of Past Significance, Present Significance and Future Significance. As for modern applications, the author reviewed currently used applications and considered the possible ways to restore its original value as an alternative for future medical science.
