In most shipbuilding company, cutting procedure is proceed by cutting machine which run by CNC(Computer Numerical Code) data. In our cutting process, all CNC data is created by our nesting post processor system automatically. Among them, in case that cutting piece in the remnant plate, our system creates only one piece CNC data. Because remnant plate is not typical shape, and ship designers don't know remnant plate shape and quantity. In can happen some merit and good point if we modify 1:1 piece NC data by shorten cutting path, reducing cutting time or re-arrangement piece. For modifying cutting data, outside workers have to call to ship designer or have to go to NC control room where control the CNC system and cutting machine. It makes stop work process, and it waste time. In this paper, we introduce a program that can modify and replace 1:1 NC data with continuous or common NC data automatically.

Uterine myoma is benign tumor formed from muscular and connective tissues, which is one of the most common tumors found in women's reproductive organs. Uterine myoma is the most common pelvic tumor and they are diagnosed in up to15 to 20% of women in pubertal period. Although myoma is generally considered to be a slowly growing tumor, in 20-40% of women at the age of 35 and more have uterine myoma of significant sizes with severe clinical symptoms. The most common symptoms include abdominal pain or discomfort, low abdominal pressure sensation, hypermenorrhea and urinary symptoms. The treatment of uterine myoma is just observation, operation and hormone replacement therapy. We treated 6 outpatients who has uterine myoma and visited Kyungwon InCheon Oriental Hospital with Herb-medication and acupuncture. So we have gotten good result from them. After 6 outpatients had taken Guichulpazing-tang(歸朮破?湯), the symptoms were　improved and the size of the uterine myoma was reduced significantly, It proves　that oriental medical treatment is effective on the patients with uterine myoma, but　continuous studies are needed.

The purpose of this study is to examine and investigate the characteristics of locational facilities and the purchase and leisure patters of residents with its focus on downtown streets of Yeongam-eup which is a eup-level small town. In the subject downtown streets, commercial and residential functions coexisted. While most locational facilities were small-scale sale(buy), food(eat), and employment(public institutions) facilities which were needed for neighborhood life and supporting daily life, the lack of facilities which supported leisure life(enjoy) and represented small town identity was found. The most common frequency of using downtown streets by residents was 'almost everyday'; the most common intention to use was 'to purchase daily things'; and the most common purchase good was 'groceries', followed by farming machines, books, and stationery. It suggested that the use of downtown streets was characterized by daily neighborhood life. In particular, it was found that expensive goods(more than 500,000 won) were commonly purchased in neighboring middle or large cities. Thus, it is necessary to consider the option and professionality of goods. Finally, it is necessary to consider residents' accessibility through reorganizing a street form from car-focused to pedestrian-focused.

Myofascial pain syndrome is a common cause of physical disability and reduces the activity of the patient. The purpose of this study was review and analysis efficiency of myofascial pain syndrome with low back pain on 50 case who were treated at the Tae Jon Nam, Myung Ho rehabilitation clinic, from January 1, 1994 to May 31, 1994. The results of this study are as follows : 1. of the 50 cases, 24(48.0%) were male and 26(52.0 %) were female. The most common age group was 40 to 30 years old. 2. The most common duration of the treatment and onset were more than 25 months with 22(44.0 %) and less : 3. As for a major causative disease of low back pain with myofascial pain sndrome, without known cause(30.0 %), lifting object(16.0 %), post exercise(14.0 %) and heavy work(12.0 %). 4. Involved muscle with low back pain reviewed I. C. L(31.0 %), Q. L, Gluteus and others muscle(23.0 %). 5. Disease history and treatment duration were proportioned. 6. Involved muscle distribution for causative disease was 26.0 % post exercise to I. C. L, 33.5 % lifting object to Q. L, 40.0 % without known to gluteus. 7. Low back pain with syndrome was buttock and thigh Pain with 44.0 %, only low back pain with 36.0 %. 8. The improvement by physical therapy on the low back pain was good 24.0 %, fair 56.0 % etc respectively. * I.C.L : Iliocostalis lumborum * Q.L : Quadratus lumborum.

국립경주박물관 미술관 신축과 관련하여 미술관 부지의 우물지(I-지역)와 공동구부지의 우물지(II-지역)에서 총 588점의 자연목의 시료가 출토되었으며 32종의 수종이 식별되었다. 가장 높은 점유비율을 차지하는 수종은 감나무와 물푸레나무류의 수종으로 나타났다. 그 다음으로 소나무, 상수리나무류, 졸참나무류, 밤나무등의 참나무과의 수종, 개살구나무류, 복사나무류, 윤노리나무류등의 장미과의 수종이 높은 점유율을 나타내었다. 두 지역은 서로 인접하고 있었던 바 수종의 점유율에 큰 차이가 없었다. 식별된 수종들은 열매를 식용할 수 있는 유실수가 많았으며 아름다운 외형과 재질이 우수하여 가공이 용이하여 이용하기 쉬운 좋은 수종들임을 알 수 있었다.

This paper presents two advanced hybrid pulse-width modulation (PWM) strategies for multilevel inverters (MLIs) that provide both common-mode voltage (CMV) elimination and current ripple reduction. The first PWM utilizes sequences that apply one switching state at the double ends of a half-carrier cycle. The second PWM combines the advantages of the former and an existing four-state PWM. Analyses of the harmonic characteristics of the two groups of switching sequences based on a general switching voltage model are carried out, and algorithms to optimize the current ripple are proposed. These methods are simple and can be implemented online for general n-level inverters. Using a three-level NPC inverter and a five-level CHB inverter, good performances in terms of the root mean square current ripple are obtained with the proposed PWM schemes as indicated through improved harmonic distortion factors when compared to existing schemes in almost the entire region of the modulation index. This also leads to a significant reduction in the current total harmonic distortion. Simulation and experimental results are provided to verify the effectiveness of the proposed PWM methods.

We report a case of celiac artery dissection after abdominal blunt trauma. A 29-year-old man visited the emergency room for acute left periumbilical pain after abdominal blunt trauma from his child. Computed tomography showed a wedge-shaped splenic infarction with splenic artery thrombus. He was hospitalized for careful observation, and after two days, follow-up computed tomographic angiography showed a progressed celiac artery dissection that involved common hepatic artery and an increased extent of splenic infarction. He underwent conventional angiography, and a self-expandable stent was placed between the celiac axis and the common hepatic artery. After two days, follow-up computed tomographic angiography showed good hepatic arterial blood flow via the stent and no progression of splenic infarction. After ten days, he was discharged without complications.

This paper presents conducted emission noise measurement from electronic equipment in frequency range of 1 MHz up to 30 MHz by small loop antenna. Small loop antenna measurement method can measure common-mode (CM) and differential-mode (DM) component of the noise on a pair of power line at the same time. The CM and DM can be measured separately. The theory of this measurement method is introduced and analyzed. The measured results were compared with the conventional measurement by Line Impedance Stabilization Network (LISN) and result a good trend between those methods.

The judgement of how good a memorial park is designed in terms of representing symbolic meanings through moonument depends on whether it decisively reflects peoples' common value and affection to specific event or place of the park. It is in fact, not easy to define the kind of value and affections peoples have in mind for the park. It is likely that most park design concepts are primarily based on designer' subjective view of the world by which the public is expected to understand, accept, and eventually share the common symbolic meanings of the park. AS memorial park design as the works of art might be appreciated not only in view of artistic performance of designer but in terms of its social meaning of the newly defined space. Two cases of park designs by author include issues on conceptual alternatives, experience of memorial space, symbolic use of materials, and perspectives on the direction of contemporary park design. It is noteworthy that authentic approaches should be challenged for a new way in which symbolic meanings could be given in rather contradictory style.
