  • Stearic acid (SA), polyethylene glycol (PEG), and malic acid (MA) have been used to modify the surface of waste gypsum to develop corresponding poly (butylene adipate-co-terephthalate) (PBAT) composites. According to the mechanical properties, MA-treated gypsum (MA-gypsum) showed the best performance, whereas SA-gypsum showed the worst performance. In contrast to SA and PEG (having -COOH and -OH as polar functional groups, respectively), the presence of both -OH and -COOH in MA is responsible for the superior surface treatment of gypsum and its better dispersion in the polymer matrix (as revealed by FE-SEM analyses). The presence of long aliphatic chain in SA is supposed to inhibit the dispersion of SA-gypsum. Further, the performance of MA-gypsum/PBAT was enhanced by adding polylactic acid (PLA). The maximum optimized contents of MA-gypsum and PLA are 20 and 7.5 wt% for developing a high-performance PBAT composite.

  • Tough study of movement of Tae-Geuk-Guan(太極拳), we understand Tae-Geuk-Guan(太極拳) & essential movement. Theory about creator of Tae-Geuk-Guan(太極拳) is indistinct. there are Jangsampung-theory(張三豊設), Wangjongak-theory(王宗岳設), Jinwangjung-theory(陳王廷設), Jinbok-theory(陳卜設). Tae-Geuk-Guan(太極拳) is military arts developed before Song empire(宋). Tae-Geuk-Guan(太極拳) has many branch.(Jin-sik陳式, Yang-sik楊式, Mu-sik武式 O-sik吳式, Son-sik孫式) Tae-Geuk-Guan'(太極拳) manual movement use fist(拳), palm(掌), hook shape(鉤) and its using form has many type like Bung, Yi, Jae, An, Chae, Yul, Ju, Go. Its gait has many type like Sang-bo(上步), Tae-bo(退步), Jin-bo(進步), Deng-gak, Bun-gak(分脚), Bak-gak(拍脚). Essential theory of Tae-Geuk-Guan(太極拳) is Yi-Sim-Hang-Gi(以心行氣) & Yi-Gi-Un-Sin(以氣運身). It means mind(心) moves qi(氣) and qi(氣) moves body(身).

  • Park Tae Won is one of the physicians that participated in the treatment of King Injo in "承政院日記(Seungjeongwonilgi, official records of incidents during the Joseon Dynasty)". The purpose of this study is to look into the forms of actual medical treatment, social status and activities of the physicians at that time by organizing Park Tae Won's records as a physician and his other works. Park Tae Won was originally an acupuncturist for the royal medical department but he performed other activities such as actual diagnosis and drug prescriptions. More concretely it seems that he used methods mentioned in "鍼灸經驗方(Chimgugyungjeonbang)". Park Tae Won held concurrent positions as royal physician as well as provincial governor. It is suspected that physicians were named provincial governors of metropolitan areas so that they could be brought in immediately when in need and so that the capital centered medical service could be distributed to other provinces. We can also presume that the appointment of physicians as provincial governors was part of the government policy to efficiently distribute aid to the common people. From this study we can conclude that the physicians of that time did not commit solely to their jobs but also held important social positions that led the Joseon society.

  • 본 논문에서는 효율성 높은 차선 인식 및 장애물 검출을 위한 알고리즘을 제안한다. 입력된 영상을 배경영상과 도로 영상으로 나눈 후 도로영역에서 Hough 변환을 이용하여 차선을 검출 하도록 한다. 또한 자동차의 그림자와 같은 특징 정보를 활용하여 주행 중인 차량을 검출한다. 영상의 잡음을 최소화하기 위한 알고리즘을 적용하여 파선 인식률을 높일 수 있는 방법을 연구한다.
