This article examines the shape, iconography, and creation date of the Four Buddhist Heavenly Kings (Sacheonwang 四天王) enshrined in the Heavenly Kings' Gate (Cheonwangmun 天王門) of Hoeamsa in Yangju, Gyeonggi Province during the early Joseon Dynasty. First, small fragments of clay decoration excavated from a fourth-platform gate site of the Hoeamsa Temple Site in Yangju Gyeonggi Province were analyzed and compared to other Four Heavenly Kings enshrined in the (Cheonwangmun gates) during the Joseon Dynasty. In addition, the size and shape of the gate were compared to other Cheonwangmun gates constructed during the Joseon Dynasty. Results revealed that the excavated fragments were part of the armor of Sacheonwang, and the clay-standing statues enshrined in the fourth-platform gate of Hoeamsa Temple would be proportional in size to those of Beopjusa Temple in Boeum, South Chungcheong Province. The flame-type pieces, which decorated the Heavenly King's crown in the Joseon Dynasty, and the rectangular-type pieces were not found in artifacts from the Goryeo Dynasty. Therefore, the Sacheonwang sculptures of the Hoeamsa Temple were likely made in the late 15th century in the early Joseon Dynasty. A detailed iconography of the Sacheonwang of Hoeamsa is presumedly based on the Buddhist paintings and illustrations of Buddhist scriptures (Gyeongbyeonsangdo 經變相圖)from the late Goryeo and early Joseon. During the late Goryeo Dynasty and early Joseon Dynasty, Traditional iconography from Goryeo and new iconography from Ming coexisted. However, in the late 15th century, the Sacheonwang statues of the early Joseon Dynasty had many different elements from those of the Goryeo Dynasty and were similar to those enshrined in Cheonwangmun Gate during the Joseon Dynasty. The Four Heavenly Kings of Hoeamsa Temple, believed to have been produced in the late 15th century, has historical significance in the following points. They were the first Joseon Sacheonwang statues example enshrined in the Cheonwangmun gate. In addition, they were established as a new tradition that influenced the iconography of the Four Heavenly Kings during the Joseon Dynasty.

Objectives : Because shipyard workers are involved with various manufacturing process, they are exposed to many kinds of hazardous materials. Welders especially, are exposed to bisphenol-A (BPA) during the welding and flame cutting of coated steel, This study was conducted to assess the exposure status of the endocrine disrupter based on the job-exposure matrix. The effects of the genetic polymorphism of xenobiotic enzyme metabolisms involved in the metabolism of BPA on the levels of urinary metabolite were investigated. Methods : The study population was recruited from a shipyard company in the f province. A total of 84 shipbuilding workers 47 and 37 in the exposed and control groups, respectively, were recruited for this study. The questionnaire variables included, age, sex, use of personal protective equipment, smoking, drinking and work duration. The urinary metabolite was collected in the afternoon and correction made for the urinary creatinine concentration. The of the CYP1A1, CYP2E1 and UGT1A6 genotypes were investigated using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) methods with the DNA extracted from venous blood. Results : The urinary BPA level in the welders group was significantly higher than in the control group (p<0.05). The urinary BPA concentration with the wild type UGT1A6 was higher than the other UGT1A6 genotypes, but with no statistical significant. From themultiple regression analysis of the urinary BPA, the regression coefficient for job grade was statistically significant (p<0.05). Conclusions : The grade of exposure to BPA affected the urinary BPA concentration was statistically significant. However, the genetic polymorphisms of xenobiotics enzyme metabolism were not statistically significant. Further investigation of the genetic polymorphisms with a larger sample size is needed.
