This study is an attempt to explore the professional image of librarianship through librarians' subjectivity using Q-methodology based on intraindividual difference in significance. The study identified four types of the professional image of librarianship and discussed their relationship; the ambivalent, the prideful, the advanced, and the critical. Each types are unique, not inter-exclusive characteristics reflected the context of the present. Also, all types have a positive image toward the librarianship.

Scientific texts are some of major sources for scientific understanding. Therefore, reading scientific texts should be considered as an important learning activity. However, there is little research about reading scientific text in Korea. In this study, as a starting point for research about reading scientific text, lists of scientific text constituents and scientific text functions are suggested based on a comprehensive literature review. The study also reviewed how scientific text structure, familarity of scientific text and analogy involved in scientific text can affect students' scientific understanding through reading scientific text. Finally, further study plans, such as analysis of actual science textbooks using the lists suggested in this study as well as the investigation of actual students' thinking processes when reading scientific text, were described.

The purpose of this study is to design the classification system for christian information resources on the internet in Korea. For this purpose, the study is investigated the divisions of Christianity of (1) library classifications: KDC, DDC, LCC, (2) portal sites: Daum, Empas, Naver, (3) Christianity Portal sites GodPeaple, Kidok, Godpia. And it compared the classification systems of KDC, DDC and GodPeaple. This study selected criteria as follows: comprehension, logicality, definiteness, efficiency and current topics. It suggested the classification system(draft) for christian information resources on internet which are composed of 10 classes.

Researches on inequality in Korean society has been sporadically conducted in various areas. In this study, research trend related to inequality was analyzed through basic statistical analysis, co-occurrence analysis, and main path analysis using articles related to inequality from Korea citation index. In basic statistical analysis, key authors, journals, and articles are identified. In co-occurrence analysis, income inequality, educational inequality, welfare inequality, and policy on inequality were identified as main topics. Main path analysis showed two research trends after 2004. One was research trend on economic inequality, and the other was on health inequality and social structural inequality.

In this paper, a theory for the static analysis of large plastic deformations of 3-dimensional frames, aiming at application to the collapse analysis of ship structures, is presented. In the frame analysis formulation, effects of shear deformations are included. A plastic hinge is inserted into the field of a beam end, and post. failure deformation of the plastic hinge is characterized by finite rotations and extensions. In order to model deep web frames of ship's structures into a framed structures, collapse of thin-walled plate girders is investigated. The proposed analysis method is applied to several ship structural models in the references.

선형탄성이론을 기초로 한 구조해석의 경우 사용하중상태에서의 변형과 응력은 만족할 만한 결과를 나타내지만, 항복후의 처짐과 파괴시의 극한하중 산정의 정확한 해석이 불가능하다. 평판의 극한해석시, 상한계 이론을 바탕으로 한 항복선 이론이 널리 사용되고 있으나 이론적으로 평판의 강도를 과대평가하게 된다. 그러므로, 임의의 하중조건과 경계조건에 대한 비선형 거동과 극한내하력을 산정할 수 있는 해석기법이 필요하다. 평판의 정확한 극한하중을 위해 p-Version 유한요소법을 제안하며, p-Version의 해석치를 범용 구조해석 프로그램인 ADINA의 결과와 문헌의 이론치와 비교하였다.

홍대용(洪大容, 1731~1783)이 저술한 "담헌서(湛軒書)" 외집 권6의 <주해수용(籌解需用)>에는 수격식 천문시계인 혼상의(渾象儀)에 대한 기록이 나온다. 우리는 홍대용 혼상의에 대한 구조와 작동 메커니즘에 대한 연구를 통해 복원 모델의 개념설계를 진행하였다. 혼상의는 세 개의 환(環)과 2개의 층(層)으로 되어 있다. 외층에 해당하는 환 구조는 자신이 제작한 혼천의인 통천의(統天儀) 구조와 유사하다. 내층에 해당되는 혼상구에는 별자리와 은하수를 그려넣고, 태양과 달의 모습을 구슬 형태로 매달아 천상의 운행 모습을 구현하였다. 통천의는 추동력으로 운행되며, 혼상의는 물에 의한 수격방식으로 운행된다. 홍대용의 수격방식은 조선에서 전통적으로 사용한 동력체계로 중국의 대표적 천문시계인 수운의상대의 동력체계를 간소화시켰다. 혼상의에 대한 기록은 조선시대 수격식 동력체계를 다룬 거의 유일한 문헌기록으로 수격식 작동 메커니즘 연구에 중요한 단서를 제공해 주고 있다.

This study aims to identify and comprehensively view health information-related research trends using a bibliometric analysis. To this end, 1,193 papers from 2002 to 2023 related to "health information" were collected through the Korea Citation Index (KCI) database and analyzed in diverse aspects: research trends by period, academic fields, intellectual structure, and keyword changes. Results indicated that the number of papers related to health information continued to increase and has been decreasing since 2021. The main academic fields of health information-related research included "biomedical engineering," "preventive medicine/occupational environmental medicine," "law," "nursing," "library and information science," and "interdisciplinary research." Moreover, a co-word analysis was performed to understand the intellectual structure of research related to health information. As a result of applying the parallel nearest neighbor clustering (PNNC) algorithm to identify the structure and cluster of the derived network, four clusters and 17 subgroups belonging to them could be identified, centering on two conglomerates: "medical engineering perspective on health information" and "social science perspective on health information." An inflection point analysis was attempted to track the timing of change in the academic field and keywords, and common changes were observed between 2010 and 2011. Finally, a strategy diagram was derived through the average publication year and word frequency, and high-frequency keywords were presented by dividing them into "promising," "growth," and "mature." Unlike previous studies that mainly focused on content analysis, this study is meaningful in that it viewed the research area related to health information from an integrated perspective using various bibliometric methods.

The meaning of the diamond crystal structure and the formative beauty of the crystal form were designed from a new perspective and expressed in jewelry. In this study, we examined the literature on the crystal structure of diamonds and analyzed cases of jewelry design based on the formative characteristics of diamond crystal structure. we newly interpreted the meaning and value of diamond crystal structure, and studied the figurative design that can show the aesthetic effect of the crystal structure by designing the diamond crystal structure as jewelry. By presenting jewelry designs that take advantage of the symmetry effect of the diamond crystal structure and the repetition of the sculptural beauty, we hope that the fundamental beauty and cultural meaning of gemstones will be re-recognized.
