  • Git's commit messages manage the history of source changes during project progress or operation. By utilizing this historical data, project risks and project status can be identified, thereby reducing costs and improving time efficiency. A lot of research related to this is in progress, and among these research areas, there is research that classifies commit messages as a type of software maintenance. Among published studies, the maximum classification accuracy is reported to be 95%. In this paper, we began research with the purpose of utilizing solutions using the commit classification model, and conducted research to remove the limitation that the model with the highest accuracy among existing studies can only be applied to programs written in the JAVA language. To this end, we designed and implemented an additional step to standardize source change data into natural language using GPT. This text explains the process of extracting commit messages and source change data from Git, standardizing the source change data with GPT, and the learning process using the DistilBERT model. As a result of verification, an accuracy of 91% was measured. The proposed model was implemented and verified to ensure accuracy and to be able to classify without being dependent on a specific program. In the future, we plan to study a classification model using Bard and a management tool model helpful to the project using the proposed classification model.

  • This study aims to discover historical trends and change of form of all stupas in India with observation of field study that is as direct as possible, by classifying, analyzing, and synthesizing the stupas. Study of Indian stupa in Korea has a number of shortcomings since only introductory partial approach has been made in order to seek the origin of Korean pagoda. This study also aims to correct errors of stupa terminology in Chinese character committed by misinterpretation of Hindi language which was established by precedent Japanese scholars several decades ago. Piled-up stupas were totally destroyed by pagans, therefore their remains tell us only of structure, material, sizeand disposition. However remains of carved stone at torana and drum give us clues as to the original form of stupa and worshipping activity, as well as change to a more luxurious form. Many rock cave stupas of India show us both simple forms matching the ascetic age of early Buddhism and luxurious changes in Mahayanan era introducing us to statues of Buddha. Indians recovered the spheric form of 'anda,' a Hindi term meaning cosmic egg, from the hemispheric form of the piled-up stupa. Therefore we might discard the erratic term of 'bokbal', which means an upset vessel. Railings and parasols became main factors of stupa design. Carved railings around stupa became a sign of divinity. Serious worshipping activity made drums long or high and created multi-embossed stripes. Bases of circular drums of some cave stupas changed their shapes to rectangular or octagonal. Single parasols became multiparasols of affluent flowerlike curved stems on carved stupa. Multistoried, elongated and high parasols of Gandhara stupas are closely related to such factors as diverse changes of form in Indian subcontinent. Four-sided torana gate and ayaka column of the circular form of original stupas suggest the rectangular form of subsequent East Asian pagoda, and higher and wider base of Indian stupas became the origin of East Asian rectangular pagoda.

  • Even though the historical changes of the Cold War, they does not release the Cold War structure in Korean peninsula. And continues North Korea's provocations against South Korea. A factor of instability in Northeast Asia is the causing catastrophic inter-Korean relations and North Korea's Yeonpyeong shelling and provocation of the Cheonan battleship sinking by an explosion. These behaviors have been committed by among the North Korea military. North Korea's provocations made by a complex decision-making system in the United States and North Korea and South Korea. North Korea's aggressive military actions are conducted under the North Korean political system of strategies unification of the Korean peninsula. It has a duality of continuity and change, depending on the situation of a foreign policy in North Korea. If North Korea want maintain structure of their country, they should change the national policy and strategy, tactics and the military action type. North Korea should be a member of international community. As one of the country in the world, North Korea create economic power, nuclear tensions break, and participate in the international community for the peace.

  • A human face figure is a visual symbol of identity. Each different face per person is a critical information differentiating each person from others and it directly relates to individual identity. When we look back human history, historical change of recognition for a face led to the change of expression and communication media and it in turn caused many changes in expressing a face. However, there has not been no time period when people pay attention to a face more than this time. Technically, the advent of computer graphics opened new turning point in expressing human face figure. Especially, a visual image which can be produced, saved, and transferred in digital has no limitation in time and space, and its importance in communication is getting higher and higher. Among those visual image information, a face image in digital is getting more applications. Therefore, 3d (3-dimensional) expression of a face using computer graphics can be easily produced without any professional techniques, just like assembling puzzle parts composed of the shape of each part ands texture map, etc. This study presents a method with which a general visual designer can effectively express 3d type face by studying each producing step of 3d face expression and by visualizing case study based on the above-mentioned study result.

  • The purpose of this study was to examine the changes and the characteristics of the attitudes toward children and spaces provided for them. by analyzing people's daily lives in housing spaces and architects' floor plans between the 1920s and the 1960s. Different kinds of data were obtained from a variety of early literature, research reports, newspaper articles, historical documents, and magazines from the period. Findings of this study are as follows: 1. Before modernization in Korea, children had been regarded as immature persons. Confucian ideas of children viewed them as 'small adults' or 'immature adults.' Thus spaces for children's daily lives were neither differentiated from those of the adults' nor deemed important. However, since the Western invasions and colonization by Japan, a remarkable change in the attitudes toward children took place. Children began to be considered a hope for the future as well as members of modem families. In addition, the introduction of the new word, 'eorini (children),' by Mr. Bang Jeonghwan, brought about a significant change in social consciousness of children. 2. The appearance of 'adongshil (children's room)' on architects' floor plans, which was a result of the social critique against androcentrism during the l930s and 1940s, was highly meaningful. The new floor plans not only emphasized rationalization of the space but also upgraded the children's status in the family. 3. Since the liberation (1945), children's space was differentiated from parental spare by the introduction of private rooms and shared spaces. The privacy of each generation was expressed by the division, and the generations were considered equal in this space distribution. In conclusion, the appearance of children's rooms required conflict-laden changes of social ideals and of the family system. It also was a symbol of modernization.

  • This study first investigates the changes of the mean and extreme temperatures and precipitation in East Asia (EA) under stabilized 1.5℃ and 2℃ warming conditions above preindustrial levels provided by HAPPI project. Here, five model with 925 members for 10-year historical period (2006~2015) and 1.5/2.0℃ future warming scenarios (2091~2100) have been used and monthly based data have been analyzed. The results show that the spatial distribution fields over EA and domain averaged variables in HAPPI 1.5/2.0℃ hindcast simulations are comparable to observations. It is found that the magnitude of mean temperature warming in EA and Korea is similar to the global mean, but for extreme temperatures local higher warming trend for minimum temperature is significant. In terms of precipitation, most subregion in EA will see more increased precipitation under 1.5/2.0℃ warming compared to the global mean. These attribute for probability density function of analyzed variables to get wider with increasing mean values in 1.5/2.0℃ warming conditions. As the result of vulnerability of 0.5℃ additional warming from 1.5 to 2.0℃, 0.5℃ additional warming contributes to the increases in extreme events and especially the impact over South Korea is slightly larger than EA. Therefore, limiting global warming by 0.5℃ can help avoid the increases in extreme temperature and precipitation events in terms of intensity and frequency.

  • This study understands rockers of today and supplies basic data of design and manufacture studying pattern change of rockers arisen in West, there is the purpose. Also, this study is investigated by dividing theoretical background of rockers, 7 kinds of American traditional rockers and European rockers from 18th century to opening part of 20th century and contemporary rockers since 20th century. The theoretical background and the style of 2 rockers (Windsor rocker, Boston rocker) were investigated to study the stylistic changes of rockers. Originally a rocker was invented by a European farmer around 1700. It developed to a household which equip practicality and comfortablness in the United States than Europe. Early rockers in a primal form appeared in the 1740s in the United States. American early rockers connected skate to established chair bridge. Rockers are deep connection with family's emotion. Rockers can provide playing functions for children and medically treating functions for adults. Windsor Rockers developed by attaching skate is mammy bench and according to shape of back form bow or hoop-back rocker, birdcage rocker, comb-back rocker. Windsor Rockers formed peculiar American tradition of craftsman furniture through structure that have a unique back of a chair and round seat. Boston Rockers were the first chairs made by mass production method. They show a particular shape with S-curve style seat and rectangular crest at the upper part of the back. Often Crests were decorated by stenciled pattern with curled leaves such as rosettes and scrolled designs.

  • Observation data (1981-2014) and climate change scenario data (historical: 1981-2005; RCP 2.6 and 8.5: 2006-2100) were used to analyze occurrence and future outlook of the extreme heat days and tropical nights in Daegu and Jeju. Then we compared the mortality and observations data (1993-2013). During 1981-2014, the average of extreme heat days (tropical nights) was 24.41 days (12.47 days) in Daegu, and 6.5 days (22.14 days) in Jeju. Extreme heat days and tropical nights have been similarly increased in Daegu, but tropical nights increased more than extreme heat days in Jeju. Extreme heat days and tropical nights in both, Daegu and Jeju showed high correlation with daily mortality, specifically Daegu's correlation was higher than that of jeju. The yearly increasing rate of extreme heat of the future (2076-2100) was 1.7-3.6 times and 7.8-37.7 times higher than the past (1981-2005) in Daegu and Jeju, respectively. The yearly increase rate of tropical nights of future was 2.6-5.0 times and 2.9-5.6 times higher in Daegu and Jeju, respectively. During 2006-2100 periods, the trend of extreme heat days was observed both in Daegu and Jeju. On the average, extreme heat days and tropical nights in Jeju increased more than that of Daegu. However, the trend of extreme heat days increase in Daegu was higher than that in Jeju, whereas, the trend of tropical nights in Jeju was higher than that in Daegu.

  • This study explores women's Wonsam in the 18th century. Wonsam was women's wedding dress, one of the representative ceremonial garments of Korea. Wonsam began to appear in the excavated clothes around the 18th century, and we can find drawings and records of the period in Yongjae Collections by Kim-kunhaeng. The form of Wonsam after the 17th and 18th centuries showed the changes in which Seop and Mu disappeared in Baeja form of Danryoung(團領) and the right and left symmetry and side slits were highlighted. The change also included wide and long sleeves and Sakdong(색동) colorful strips on the sleeves), Hansam ornaments, and the use of the belt, which means the change of Baeja composition into our traditional costume of the age. Through the Colletions, we notice that women wore Wonsam in different colors and with varying hair accessories according to the nature of ceremony, the social status, and marital status. Concerning Wonsam, the color of clothing for the dead woman was green(喪禮), while that for marriage ceremony was red(婚禮). Wonsam with the light color was for ceremonial clothing(祭禮). The women who served in the palace wore green Wonsam and Geodumi, while a bride at the marriage ceremony wore red Wonsam or a red long-sleeved robe with Jokduri. At the ceremony of Hyeongunorye, women wore Wonsam with a wig. the dead woman wore Yemou.

  • South Korea has strengthened the eligibility criteria for childcare teachers while amending the Infant Care Act in January 2005 in order to improve the quality of childcare services. Since then, there was a change in the legal basis related to childcare staff such as introduction of national certification of childcare center directors, name change, strengthened qualification standards for directors and teachers, training system maintenance and repair, strengthened credit standards of teachers' care related qualification courses, and maintenance provisions of continuing education nursery teacher qualifications. And that is because childcare staff are closely related to the quality of childcare, and a very important variable who has direct influence on infants. This study, through literature research and analysis, describes the status and development direction of childcare staff. This study covers three main aspects. First, the relevant historical flow was reviewed and the concepts of the role, expertise, and legal status of childcare staff were investigated. Second, staff training institutions, emissions certification, employment, and the status of treatment were investigated. Third, development direction for the training system, eligibility criteria, continuing education and its training system, and treatment improvement were proposed.
