본 연구에서는 볼 엔드밀을 사용한 5축 가공에서 공구 간섭회피를 위한 효율적인 알고리즘과 가공 가능한 많은 자세들 중에서 공구 절삭부위와 이전자세를 고려한 공구 자세설정 알고리즘을 개발 하였다. 공구 간섭검사는 공구 밑면 간섭과 몸체 간섭으로 나누어 순차적으로 수행하고, 공구 몸채 간섭이 없는 공구 자세를 설정한다. 공구 몸체 간섭검사는 곡면의 다각형 모델과 공구 축과의 관계를 사용하여 행한다. 간섭이 발생하였을 경우 간섭회피 및 자세조정 영역으로 설정하고 유효한 공구자세의 범위를 정한 후, 이 범위 내에서 공구 절삭 부위 및 이전 자세를 고려한 효율적 공구자세를 사용하여 공구경로를 산출하였으며, 시뮬레이터를 통해 그 유효성을 검증하였다.

The purpose of this study is to analyze the unique characteristics of the vernacular house of Ulleung-Do(island), which shows a different residential culture from the main land. For this purpose, this study examined the characteristics of the location, spatial arrangement, and floor-plan of the house and also tried to understand how these basic elements were changed and why these changes were occurred. The result of this study is as follows: First, the house was located on the mountain area and was oriented toward the various bearings. Second, the house usually did not have annexes and most residential space was installed on a main building. Third, the floor-plan of the house was developed from a basic two-Kan (with single row) house type in a early settlement period to three-Kan, four-Kan, and five-Kan house types in later periods. While the development of house type proceeded. the main building was functioned as a complex space for both residential and storage purposes. Some houses were gradually developed into a middle and upper-class house shape by installing annexes. The change of the floor-plan and the house size was the result of self-sustained living culture influenced by the natural environment of the island and of changes of residential conditions as well.

표준 자바 클래스 라이브러리는 용용 프로그램에 의해 요구되는 플랫폼 의존적인 기능을 수행하지 못한다. 따라서 플랫폼 의존적인 기능을 포함한 자바 응용 프로그램은 JNI를 사용한 네이티브 함수를 호출하여 부족한 기능을 수행하여야 한다. 네이티브 언어 프로그래머는 다양한 자바 객체와 연결하고 사용 후 이를 해지해야하는 작업을 명시적으로 기술해야 한다. 이러한 번거로운 작업을 피하기 위한 방법을 본 논문에서 제안하고자 한다. 순수 자바 클래스에서 네이티브 메소드는 코드 블록을 가질 수 없다. 자바 네이티브 메소드가 네이티브 코드로 작성된 몸채를 가질 수 있도록 함으로써 프로그래머는 JNI를 의식하지 않고 프로그래밍하는 것이 가능하다. 이를 위해 네이티브 환경의 자바 클래스인 네이티브 클래스라는 개념, 그리고 자바 클래스와 네이티브 클래스 간에 제어와 자료의 교환을 지원하는 중재기를 두어 해결하였다.

The building site was presumed as the Howonjeokwon or the Dasiwonji established at the traffic route among western inland areas in old Pyeonghaegun. The groundwork was composed inclination terrace of two steps. The upper step was the territory of the main house of ceremony symbolic+lodging function and the down step was divided in the territory of both Ikrang-chae of boarding and lodging management function and the territory of Haengrang-chae pavilion of rest reception management. The building composition by each territory formed space differentiation with the line of flow according to the thorough rule of court rank. The arrangement composition set the strong center axis in tandem, and it was the building arrangement interpreting the territory and the rule of court rank by function as the relationship of master and servant and was the building type emphasizing on the whole unity with the geometric symmetry structure. The Dasiwonji and the Hyeeumwonji had the common point which is the traffic architecture of semi governmental management reinforcing the boarding lodging function in the place which a visitor stayed. The Haeeumwonji and Dasiwonji had the difference in the size, but was the same in the composition system of construction. The external space and the system of the line of flow decided from the functional territory separation and the hierarchical rank as thorough as the geometric arrangement focusing on the whole unity. Namely, it was the strict and unusual system of the line of flow depended on the thorough rule of court rank than the efficient approach or arrangement of the line of flow. After being established to be the Howonjeokwon at the end of Koryeo, it disappeared at the time of the invasion of Japanese pirates when it was the time of the King Woo in Koryeo. It is presumed that it was continued until both wars, Imjin Byeongja, ago after changing its name to the Dasiwon, being restored to the small size at the end of Koryeo at the early of Choseon.

Southern Royal Villa served as an accommodation for the prince in early Joseon Dynasty, and as an official residence and banquet room for Chinese diplomats in the later period. It was facing south and was located at the southern part of the old town of Seoul and to the north of the Southern Gate. The place was divided into four parts: the outmost, the middle, the inner-middle and the inner part beginning from the south and with important buildings placed in the inner part. The residence for the first and the second highest diplomats was situated at the northernmost location. The residence for the highest diplomat was a two-story building. On the west side of the residence was the large scale Western Banquet Room. It consisted of a single wide hall suited for a grand ceremony, and had the greatest formality and solemnity. On the southwestern side of the diplomatic residence was a building which was called Momchae before the early 17th century and Namru(南樓) after the 19th century. Namru in the inner-middle part is the half-sized remnant of Momchae, which used to be the largest building in the Southern Royal Villa. The title 'Momchae (meaning Main Buildling)' signifies that the building represented the entire Villa when it was built as an accommodation for princes. The layout of the Villa in early Joseon Dynasty, which was centered around Momchae, is highly likely to have been a common structure of royal villa for princes during the period.

Before the 15th century, the main buildings of the residences of the ruling class in Seoul consisted of Momchae(身梗), Seocheong(西廳), and Naeru(內樓)‧Chimru(寢樓). Based on the equality of the relationship between husband and wife, the couple lived in the main building[Momchae] in the center of the mansion, but based on the individuality of the relationship between husband and wife, each had an area consisting of the same section within the building. Naeru·Chimru was the two floors bedroom building became a common living space for the minister and wife, upstairs in summer, downstairs in winter. In preparation for large gatherings and important receptions, an open-structured West Hall(西廳) was located on the west side of the mansion. Momchae, Seocheong, and Naeru‧Chimru were the common building types and layouts of the residences of the highest ruling class, including high-ranking officials, until the reign of King Sejong. However, from around the time of King Seongjong, Seocheong and Chimru came to be regarded as privileged and luxurious buildings only allowed for the grand prince's residence. The layout of the bedroom, main building (including Wings), Outer Sarang[外舍廊], and Joyangru[朝陽樓] of Prince Bongrim's mansion built in the first half of the 17th century clearly shows the transitional period when the arrangement of chimru, main building, and western office was disrupted and the layout changed to the Inner main building(Anchae for wife) and Outer main building(Sarangchae for husband).
