A bronze dagger excavated from the historical site at Bongili in Gyeongju was examined for its microstructure and chemical compositions. The results show that it was forged out of the Cu-10 weight % Sn alloy having no lead. The application of forging in fabrication and the use of an unleaded alloy distinguish this artifact from other bronze daggers that have been reported in Korea, the majority of which were cast from leaded Cu-Sn alloys. This dagger is a rare and valuable archaeological material suggesting a unique bronze technology practiced in ancient Gyeongju area.

붓다고사(Buddhaghosa)는 불교승려이자 작가로써 상좌부불교에서 가장 뛰어난 승려로 유명하다. 그는 청결을 의미하는 Visudhimagga의 작가로서도 유명한데, 이 작품들은 정전(正典)문학의 백과사전이라 불리고 있으며, 담마의 다양한 보물 컬렉션이라 할 수 있다. 붓다고사는 Visuddhi의 순결함에 도달하기 위해 magga 형식을 설명하고 있고, 불교교리 전체를 조직적으로 설명하고 있다. 붓다고사는 스리랑카어로 쓰여진 atthakathā를 Magadyhi(빨리어)로 변역했다. 이러한 업적으로 그는 명예를 얻었고, 이 작품은 상좌부불교(Theravāda)를 연구하는 학자들 사이에서 신성한 텍스트로 여겨졌다. 최초의 붓다고사에 관한 전기문은 6세기에 쓰여진 Mahavamsa에 나타난다. 마하밤사에 따르면, 그는 큰 보리수가 있는 인도 마가다국에서 브라만으로 태어났다고 전해진다. 그러나 Buddhaghosa의 atthakathā를 연구한 Kosanbi박사는 붓다고사는 북인도로부터 온 인물은 아니라고 보았으며, 붓다고사가 미얀마 사람일지도 모른다고 추정했다. 그 이유는 다수의 atthakathā가 미얀마에서 발견되었기 때문이다. 미얀마뿐만 아니라, 태국 그리고 캄보디아 역시 붓다고사가 자국인이라고 주장하고 있다. 5세기부터 더 나아가 11세기 중반까지 하(下) 미얀마의 고대 쀼왕국에서 불교가 매우 번성했다는 지속적인 기록이 있다. 이는 5세기에 붓다고사 전설과 함께 불교를 활성화시켰으며, 상좌부불교와 관련된 조각품들과 비문을 연구하는데 반영되었다. 붓다고사의 자타카 해설은 붓다의 역사적 탄생을 다루고 있으며, 미얀마의 모든 청소년에게 오랫동안 교육자료로 활용되어 왔다. 또한 자타카 해설은 비석에서 중요한 부분을 차지하고 있으며, 테라코타 부조나 11세기와 12세기의 버간사원의 벽화에서도 사용된다. 이처럼 미얀마에서 비석과 테라코타 부조, 그리고 수많은 벽화들이 발견되는 것을 통해 붓다고사가 미얀마 출신이었다는 것을 확인할 수 있다.

This study is to provide basic data on the jobs program to identify the relevance of the professional activities and quality of life of the elderly and the elderly, were performed using the National Health and Nutrition Examination Survey.. Survey population of 1,472 patients were 65 years of age or older. The survey method, t-test, ANOVA and multilevel regression analysis was used. This study result of quality of life of elderly people with a job, unemployed elderly people appeared to be higher than the quality of life(${\beta}=0.041$, p=0.000). In work mode regular workers was an average of 0.93 points((p=0.005), in working hour full-time average 0.91 points(p=0.079), in job classification professional average 0.91 points(p=0.044) the higher the quality of life. Elderly business jobs, there is a need to improve the quality of life of the elderly to consider the results of this study work business.

In this study, we attempt to identify factors that influence the performances of Korean firms regarding global R&D cooperation, and to derive policy implications for performance improvement. The hypothetic influential factors include firms' general characteristics, purposes and types of cooperation, technology, partners and their countries, and government support. We categorize the performances of global R&D cooperation into technological, economic, and strategic performance, and analyze the effects of those factors on each of the performances as well as the overall performance. We use a standard tobit model for the overall performance, while using a multivariate tobit model for the other performances to reflect the possible correlations among them. The survey data was collected from 162 Korean firms that had previously conducted or were currently conducting global R&D cooperation.

Developing cultural contents in cultural creativity industry is very practical process recently. Research about Jeju's legend and myth should be the basic theory for cultural contents development based on local cultures. Jeju Naewotdang Musindo 10 gods paintings are unique colored pictures, appointed as Jeju folklore material No.7 and national important folklore material No. 240. Jeju-Do is remained the springhead of absorbed into unique culture for a long time because of Jeju's geographical environment condition. Jeju Musindo could be related with the symbol of Jeju's myth images and the springhead of emotions of our typical country people. It would be analysed by Wucius Wong's design style theory for approaching visual image and symbolic meaning. This research about Jeju Naewotdang Musindo 10 gods paintings could provide design analysis methodology for further theoretical studies about Jeju's legend and myth for Jeju's unique cultural contents.

Objective: In Gunsan, Jeollabuk-do, Korea, we wanted to determine if the sluggish local economy could affect citizens' health behaviors, especially mental health. Methods: We divided Gunsan-si into 5 living areas and conducted Small-Area Estimations and confirmed the modified compound estimation value using the 2013-2017 Community Health Survey data and population data from Gunsan-si. Results: The health behaviors and mental health of the residents of the western living area(Soryong-dong, Misung-dong), which is an industrial hub of Gunsan, had deteriorated or decreased compared to those of other regions. Conclusions: Although there are limitations in analyzing the community health survey data using the small-area estimation method, it could be useful data for evaluating regional gaps and health level.

Lacquerware of Goryeo period was variously developed from the early 10th century to the 14th century and became lacquerware inlaid with mother-of-pearl which shows creativity with splendid heyday. For characteristics, splendid and close mother-of-pearl. Characteristic of decoration method is to use gold painting method, Tortoise shell and metal line. Drawing is done with gold dust and gold painting method decorating lacquerware are very splendid from an artistic and decorative aspect, but gold painting is easily lost. So, it's currently difficult to find in relics succeeded. Therefore, there are domestically insufficient studies on gold painting method in Goryeo period, so this researcher intended to observe gold painting of lacquerware excavated in Goryeo period through the microscope, investigate characteristics, mixture, etc. of gold dust and provide data of studies on the recovery of ancient technology. As the result, gold dust particle has various shapes such as irregular square, polygon and triangle under the size from 2 ㎛ to 20 ㎛. The end of gold dust is rolled and overlapped and irregular particle seems to be similar to the shape of crumpled paper. This research showed that gold dust used in gold painting of Goryeo period had used gold dust made by grinding gold leaf to gold painting.

The study on the archaeological bronze artifacts in Korea has prompted much research through the analysis to determine the production technology. However, research on the smelting technology is not enough. This is associated with the lack of copper smelting and refining remains and literatures were not found. Copper smelting technology was probably developed independently, but also can not ignore the effect of the another country. Thus, many studies compared to estimate the country's copper smelting technology. In this study, smelting technology was provided and compared through the literature and smelting sites study of the domestic and foreign.

Purpose: This study analyzes and studies the characteristics of the Jeju area and uses them as basic data such as construction method design in the future development project. Method: Based on the ground survey data of the construction conducted in Jeju, the depth, relative density, N value, function state, color tone, groundwater level, and compressive strength were analyzed and studied. Result: Studies show that Jeju has columnar joints consisting of ancient volcanic activity and rapid cooling by nearby seawater, thick sand layers found on the coast, and clinker layers and Seogwipo layers formed by Mercury volcanic activity. Conclusion: It is hoped that it will be used as data for selecting basic design and basic construction method by understanding the special ground form of Jeju area and reflecting its characteristics well when designing construction.
