This study aimed to review trends in Korean medical education research from 2003 to 2022. A total of 60 studies were identified, with an increasing trend in publication numbers. The research topics covered various aspects of Korean medicine education, including curriculum, basic science, clinical science, teaching methods, history, and international comparisons. Text mining analysis revealed "Curriculum", "Satisfaction" and "Clinical" to be frequent terms. The study suggests that Korean medicine education research should continue to develop, given its broad scope and growing interest.

Due to the strong relationship between Baekje, one of the ancient Korean Kingdom and Japan through the same religion, Buddhism, it is possible to find many similarities in remains, such as temples, and pagodas, and in many relics, in both cities. However, from the point view of urban planning, Buyeo, originally designed as the fortress city, has a different city planning strategies from that of Kyoto which is a straight-lined city. After Buyeo was destroyed by Silla, one of the Three Kingdoms in Korea, it got deemphasized in Korean history. Later, Buyeo's recent city planning was directly affected and implanted in Japanese Imperialism period (1910-1945) one which emphasizes the layout of Japanese temple which serves as the center of the ceremonies for their ancestors. Thus, it is possible to find cultural interrelation in urban planning between two cities throughout the history of Korea and Japan.

This study presents a method to predict plant-specific and operational history dependent scaling factors. Realistic and detailed approaches are taken to find scaling factors at reactor coolant. This approach begins with fission product release mechanisms and fundamental release properties of fuel-source nuclide such as fission product and transuranic nuclide. Scaling factors at various waste streams are derived from the predicted reactor coolant scaling factors with the use of radionuclide retention and build up model. This model makes use of radioactive material balance within the radioactive waste processing systems. According to input parameters of plant operation history, scaling factors predicted at reactor coolant and waste streams are well brought out the effects of plant operation history.

Parrondo paradox is the counter-intuitive phenomenon where two losing games can be combined to win or two winning games can be combined to lose. In this paper, we consider an ensemble of players, one of whom is chosen randomly to play game A' or game B. In game A', the randomly chosen player transfers one unit of his capital to another randomly selected player. In game B, the player plays the history-dependent Parrondo game in which the winning probability of the present trial depends on the results of the last two trials in the past. We show that Parrondo paradox exists in this redistribution model of the history-dependent Parrondo game.

No one can tell when, exactly, the conservation of potteries & ceramics began, however, according to the documents, it has a long history. Among the materials discovered up to the present, organic adhesives extracted from animals and plants such as bitumen were mainly used and resin, in 19th century, as well. As for inorganic adhesives, clay, lime and plaster were used as well as rivet, as one of mechanical methods. According to the conservation case studies in Korea, lacquer and gilding powdered gold were applied as treatment methods in some ceramics, but, in general, plaster and resins were used widely.

This paper describes shock waveform synthesis methods for a shock response spectnlm over a short time interval with which intereference between parts within a test item is increased to perform a sufficient shock test for damage or malfunction which may be caused by the interference between parts, and a digital filter for obtaining a shock response history required for the shock waveform synthesis and a digital inverse filter for restoration by inversely using the digital filter. The time at which the maximax value occurs in the response history is detected in order to establish a delay time which is one of the parameters in the wavelet, on the condition that the natural frequency of SDOF system with a Q (quality factor) of 10 equals to the wavelet frequency of the zero delay wavelet input. A shock response spectrum over a short time interval and an abrupt change in the acceleration for an instant are illustrated as features of the synthesized waveform.

This study was conducted to identify taxonomic differences in the characteristics of Acheilognathus majusculus and A. yamatsutae during their initial life history via an interspecific hybridization experiment. Hatching time required 36 h for MY and 49 h for YM at 21.5℃, showing a significant difference of 13 h between the hybrids. The hatching rates of the cross-bred eggs were 30% for cross MY (A. majusculus♀×A. yamatsutae♂) and 40% for cross YM (A. yamatsutae♀×A. majusculus♂). The hatching larvae size was total length 3.13-3.43 mm in MY and total length 3.89-4.22 mm in YM, which was larger in YM. The hybridization test between A. yamatsutae and A. majusculus that live in the same water stream confirmed that no interspecific reproductive isolation occurred.

This study explores visitor learning in a natural history museum from the perspectives of situated learning. The purpose of this study is to understand how the visitors construct knowledge from museum experiences through dyadic discourses. The participants were two university students. They moved naturally through the exhibition with no predetermined path in a natural history museum in Korea. Data were collected in the form of audio-recorded dyadic discourses at and between exhibits and were transcribed. The transcription was coded using the conversation coding scheme, and categorized into specific learning types. The findings included (1) the characteristics of learning talks and (2) learning types created by dyadic discourses at and between exhibitions within learning contexts as museum learning experiences. Implications and future research related to visitor learning in informal learning settings were discussed based on the findings.

The objective of this study is to examine the cognitive process that undergoes a middle student’s conceptual change about the universe by the cognitive conflict, using science history materials as a teaching strategy. Four eighth graders were selected and classified by three cognitive level. Students were interviewed and conducted to an inquiry activities regarding their viewpoint about the universe after each class, and their conceptual change patterns were analysed from pre-test and post-test. This study showed that each student held dissimilar astronomical preconceptions and various misconceptions about celestial motion. Students at the formal operational stage and transitional stage experienced the conceptual change from geocentricism to heliocentricism by instructional model upon the science history materials. Student at the concrete operational stage had either unscientific conception, no conception, or could not have a conceptual change even when being presented with an environment that arouses cognitive conflict ($R^2$: Phase change of Venus and its Rise and set time). They ended up having a cognitive change from geocentricism to heliocentricism by solving another problem ($R^2$: Relation between visible diameter and position of Mars). After the instruction, a conceptual achievement progress was reported with a $10\%$ improvement. Therefore, the instruction model based upon science history was effective on student’s scientific conceptual change.

In Korea, confectionery refers to biscuits, snacks, chocolate, candy and gum. The first sweet in Korea is the Yumilkwa (oil-and-honey pastry) in the Goryeo Dynasty which was mentioned in history book, and is seen to be popular in medieval Korea. Korea's confectionery industry began in 1945 with the aid of the U.S. forces, Haitai Confectionery company produced sweets. The first confectionery product is 'Yeon yang gang'. In the 1970s and 1980s, the confectionery industry developed along with economic growth in Korea, and many of the products released at this time are still loved. Now the domestic market is saturated, sales of domestic confectionery companies are decreasing due to low-priced offers made by importers. It is necessary to develop products with high quality and brand power that can lead the market, and I think it is necessary to target the undeveloped market like the Halal market.
