This study reviewed the costume mainly on the Joseon Giroyondo(耆老宴圖) between 17th 18th Century. In Joseon Dynasty, they produced paintings to commemorate the meeting of Girohwe(耆老會), namely Giroyon(耆老宴); this painting is Giroyondo. The feature of Giroyon depended on political purpose and social phenomenon. Therefore, the composition of figures in Giroyondo and their costume were seen differently. By its character, Giroyondo was classified into official one from Giroso(耆老所), private one arranged by the participants and Court Giroyon(宮中腸宴圖). People figured in Giroyondo are roughly divided into costume in Girosin(耆老臣) officials and minor officials. Girosin officials wore Hongdalyong(紅團領) and Samo(紗帽) in official Giroyondo while they wore Hungnib(黑笠.) and Jingnyong(直領) in private Giroyondo. In Court Giroyon, which was for classy and formal Court event, they wore Dalyong(團領) and Samo but in colors of blue and green. Minor officials were observed in two categories; those who wore Samo and Gakdae(角帶), and those in Dugeon(頭巾). However, they were not showed up in private Giroyondo.

The vulcanizate structure of silica-filled compounds is affected by the filler-rubber interaction (FRI) due to the silica-rubber coupling reaction and the chemical crosslink density (CCD) of the matrix rubber. In this study, the vulcanizate structure changes of silica-filled compounds according to the silane and sulfur variation were quantitatively analyzed using the Flory-Rehner and Kraus equations. In efficiency vulcanization (EV) conditions with low sulfur content, FRI increased when the bis-[3-(triethoxysilyl)propyl]tetrasulfide (TESPT) content increased, and the CCD clearly decreased. By contrast, in semi-EV conditions with high sulfur content, as TESPT content increased, the FRI increased the same way EV conditions, but the CCD was unchanged. Based on these results, it was confirmed that FRI of the silica-filled compounds increased as TESPT content increased, but CCD decreased or retained similar values according to the vulcanization system, indicating that the formation reaction of FRI was preferred over CCD.

Purpose: At the end of life, communication is a key factor for good care. However, in clinical practice, it is difficult to adequately discuss end-of-life care. In order to understand and analyze how decision-making related to life-sustaining treatment (LST) is performed, the shared decision-making (SDM) behaviors of physicians were investigated. Methods: A questionnaire was designed after reviewing the literature on attitudes toward SDM or decision-making related to LST. A final item was added after consulting experts. The survey was completed by internal medicine residents and hematologists/medical oncologists who treat terminal cancer patients. Results: In total, 202 respondents completed the questionnaire, and 88.6% said that the decision to continue or end LST is usually a result of SDM since they believed that sufficient explanation is provided to patients and caregivers, patients and caregivers make their own decisions according to their values, and there is sufficient time for patients and caregivers to make a decision. Expected satisfaction with the decision-making process was the highest for caregivers (57.4%), followed by physicians (49.5%) and patients (41.1%). In total, 38.1% of respondents said that SDM was adequately practiced when making decisions related to LST. The most common reason for inadequate SDM was time pressure (89.6%). Conclusion: Although most physicians answered that they practiced SDM when making decisions regarding LST, satisfactory SDM is rarely practiced in the clinical field. A model for the proper implementation of SDM is needed, and additional studies must be conducted to develop an SDM model in collaboration with other academic organizations.
