We study the internal structure under the artificial mountain of Heumkyeonggak-nu, a Korean water-powered clock in the early Joseon dynasty. All the puppets on the artificial mountain are driven by the rotational force generated by the water wheel at their designated time. We design a model that work with three parts of the artificial mountain. At the upper part of the artificial mountain to the east, west, north and south, there are four puppets called the Four Mystical Animal Divinity and four ladies called the Jade Lady respectively. The former rotates a quarter every double hour and the latter rings the bell every hour. In the middle part of this mountain is the timekeeping platform with four puppets; the Timekeeping Official (Hour Jack), the Bell-, Drum-, and Gong-Warriors. The Hour Jack controls time with three warriors each hitting his own bell, drum, and gong, respectively. In the plain there are 12 Jade Lady puppets (the lower ladies) combined with 12 Oriental Animal Deity puppets. In his own time a lady doll pops out of the hole and her animal doll gets up. Two hours later, the animal deity lies down and his lady hides in the artificial plain. These puppets are regularly moved by the signal such as iron balls, bumps, levers, and so on. We can use balls and bumps to explain the concept of the Jujeon system. Iron balls were used to manipulate puppets of the timekeeping mechanism in Borugak-nu, another Korean water-powered clock in Joseon dynasty, which was developed earlier than Heumgyeonggak-nu. According to the North Korea's previous study (Choi, 1974), it is obvious that bumps were used in the internal structure of Heumgyeonggak-nu. In 1669, The armillary clock made by Song, I-young was also utilized bumps. Finally we presented mock-ups of three timekeeping systems.

In this paper, acting of Meryl Streep, who was recognized as a method actor in Hollywood, was analyzed, and this paper tried to find out how Meryl Streep utilizes the American acting method to improve her acting skills. To do this, we first looked at the concepts and theories of the American acting method, and analyze the acting of Meryl Streep through three films: "Sophie's Choice", "The Devil Wears Prada", and "The Iron Lady". Analysis results show that Meryl Streep utilizes all of the American acting methods, such as "Emotional memory", "Imagination", "Given Circumstance", and "Repetition" without any particular distinction. Meryl Streep uses not a specific acting theory, but selects appropriate training for herself. According to the analysis of this paper, we can understand the acting method that Meryl Streep uses, and shows some way to develop the acting training. The result of this paper can be used to the acting training, and it will be an opportunity to follow in the footsteps of one of the greatest actress.
