  • Purpose: The Mulliken's method is a one of the very excellent technique to correction of the unilateral cleft lip. It could decrease the need of additional operation and second operation by the early simultaneous correction of unilateral cleft lip and nasal deformity, at a time. Numerous procedures were advocated for the correction of nasal deformity, but with general dissatisfaction of the results, it became obvious that no one procedure is the ideal one. The authors have been operating on unilateral cleft lip by Mulliken's method and long term follow - up of postoperative result was evaluated. Methods: The authors have done long term follow - up of result in the 75 cases unilateral cleft lip patient, during 1 ~ 7 years. That was repaired by simultaneous correction of cleft lip and nasal deformity by Mulliken's method at the period from June, 1997 to December, 2007. The patients were unilateral complete cleft lip 39 cases, unilateral incomplete cleft lip 36 cases. In the severe complete cleft lip cases, lip adhesion operation was done before definite operation. The mean age of unilateral cleft lip operation was 3.2 months. Five anthropometric parameters, which were upper lip, cutaneous lip and vermilion mucosa height, nasal tip protrusion, columella length were measured by Sliding Vernier Caliper. The anthropometric analysis was performed preoperative and postoperative at 6 months, 3, 5 and 7 years and the results were com pared with those of age - matched, normal children. T - tests were used to analyze the differences between the measurements. Results: Long - term postoperative results were evaluated by anthropometrically. Most patients showed adequate growth of upper lip height, vermilion mucosa height and columella length. But nasal tip protrusion was relatively short compare with normal value. Incomplete cleft lip group was nearly normal growth results than complete cleft lip group. Conclusion: In conclusion, we could make harmonious Cupid's bow, natural philtrum and lip, appropriate nasal shape by Mulliken's method. But nasal tip protrusion was under the normal values on complete and incomplete group. And incomplete group was more good results than complete group. We have experienced repair of cleft lip by Mulliken's method with 75 cases of unilateral cleft lip patients and conclude that it was very useful and good method.

  • 본 연구는 19세기에 중건된 조선시대 창경궁의 내전 전각을 대상으로, 지붕가구를 구성하는 주요 부재들의 치수계획을 고찰하고 서까래의 물매를 결정하는 요소를 분석하여 궁궐건축 내전 전각에 있어서 지붕가구계획의 기법을 밝히고자 하였다. 창경궁 내전 전각의 지붕가구를 형성하는 주요 부재의 치수계획은 다음과 같다. 먼저 평주의 길이는 궁궐지의 기록과 일치하였으며 고주의 계획치수는 촌(寸)단위까지 사용하였다. 영춘헌과 같이 평주의 길이가 촌단위까지 치목되어질 때 고주의 길이는 완척으로 계획되어 평주와 고주 사이에 형성되는 장연의 물매는 일정한 값을 갖는 것으로 판단된다. 한편 초익공 부재는 대체로 1.2척(尺)의 높이를 가지며 이익공의 경우에는 0.8척으로 초익공보다 0.4척 정도 작게 나타났다. 한편 장혀의 단면 폭은 0.3척으로 규모에 관계없이 일정하며, 다만 단면 높이의 경우 0.6~0.7척으로 대별된다. 도리의 직경은 1척을 기준으로 0.1척을 가감(加減)하였으며, 장연의 직경은 전각의 규모에 따라 0.5~0.6尺의 사이에 있는 것으로 나타났다. 한국 전통목조건축 지붕가구의 형성에서 서까래의 물매결정은 먼저 장연의 물매를 정한 후, 건물의 전체 높이를 결정하는 종도리의 높이를 정하고, 중연을 걸기 위해 동자주의 위치와 높이를 조정하는 방식으로 지붕가구를 계획하는 것으로 파악되었다. 특히 장연 물매는 건물 규모에 따라 특별히 정해진 값이 있는 것이 아니라 전면 평주높이와 포작의 구성 등에 따라 자연스럽게 결정된 것으로 추정된다. 그리고 중연을 사용하는 경우 중연물매의 결정방식은 양통 어칸을 등간격으로 분할한 후, 동자주의 위치 또는 길이를 조정하는 방법을 사용하였던 것으로 추정할 수 있다.

  • Background: Hemiplegic patients usually have difficulty maintaining balance. Balance training is a major component of there habilitation program for patients with neurological impairment. The purpose of this study was to investigate the effects of PLS(Posterior Leaf Spring), FES(Functional Electrical stimulation), treadmill training, and neurodevelopmental treatment on the improvement of balance in patients with hemiplegia. Methods: We looked into published studies from Dankook University’s electronic library databases of RISS4U, KMbase, NCBI, and MEDLIS concerning the effectiveness of any form of intervention leading to improvement of balance. All types of studies relevant to the topic that were published in English during the time period of 1986 to 2005 were included. Results: 1. There were significant differences in standing balance, dynamic activity balance, and gait speed between barefoot subjects and subjects who wore SPAFO and HPAFO(p<.05). 2. The changes in ROM and FRT related to sex, age, height, and weight part of the diagnosis, as well as experience relapse, was of meaningless value. Changes in ROM related to the duration of pain and experiences of falling down were also meaningless. However, FRT showed significant static differences(p<.05). 3. The body-weight-support treadmill training scoring of standing balance, step length, and a timed 10m walking test showed definite improvement. 4. The proprioceptive control approach improved dynamic balance in patients with hemiplegia. Conclusion: Consequently, further study is needed to verify methods when physical therapists are researching balance ability in hemiplegic patient.

  • This study was conducted to investigte the visual preference and response between introduced and native trees for utilization of the south native trees in interior space. 1. The intensity of illumination was below 500lux at 24 buildings of interior spaces surveyed. Generally the temperature was 24~$26^{\circ}C$, and humidity was 60~70%. 2. Total number of introduced tree species were 9 familiar, 16 genus, 18 species, especially palm genus were the largest tree among them at these surveyed interior spaces, but native trees were only 2 species. The introduced tree of 2 to 3m in height was 46 percent, and the case of 1.2 to 2m was 42 percent. 3. The mean of visual preference was the highest at Rhapis excelsa and howeia belmoreana, and followed with Neolitsea sericea, Daphniphllum macropodum, Listsea japonicum. In the mean of visual preference for selected tree groups, native tree was not different as compared with introduced tree. 4. Visual image factor of the native and introduced trees at interior spaces was classified by individual factor and emotional factor. These 2 factors were shown 66.5% total variance. The native tree was strongly recognized on individual factor, as , and introduced tree was also strongly recognized on emotional factor. 5. In the analysis of visual preference and image, a difference between the selected groups of the introduced and native trees were not shown significant, and the introduced trees were similar to the native trees on the visual image. This result was as follow There was an analogy between Cinnamomum camphora, Ligustrum japonicum and Ficus retusa, Ficus benjamina. There is an analogy between Castanopsis cuspidata var. sieboldii, Cinnamomum japonicum and Ficus retusa, Ficus benjamina. There was an analogy between Elaeocarpus sylvestris var. ellipticus, Fatsia japonica and Rhapis excelsa, Howeia belmoreana. There was an analogy between Neolitsea sericea, Daphniphyllum macropo여, Listsea japonica and Rhapis excelsa, Howeia belmoreana. There was an analogy between Elaeocarpus sylvestris var. ellipticus, Fatsia japonica and Dracaena fragranse, Ficus elastica, Monstera deliciosa.

  • Objective : Percutaneous vertebroplasty (VP) can provide immediate stabilization in pathologic fractures of spinal tumors. However, long term follow-up data in cases of pathologic fractures are lacking. The authors report follow-up results of VP in 185 pathologic fractures of 102 spinal tumor patients. Methods : Percutaneous VP was performed at 185 vertebral bodies of 102 patients from 2001 to 2007. Retrospective analysis was done with medical records and radiological data. The change of visual analogue score (VAS), vertebral body (VB) height and kyphotic angle were measured preoperatively and on postoperative one day and at 3, 6, and 12 months. Results : The patients were composed of metastatic spine tumors (81%) and multiple myeloma (19%). Involved spinal segments were between T6 and L5. Mean follow-up period was 12.2 months. VAS for back pain was 8.24 preoperatively, 3.59 (postoperative one day), 4.08 (three months) and 5.22 (one year). VB compression ratio changed from 21.33% preoperatively to 13.82% (postoperative one day), 14.36% (three month), and 16.04% (one year). Kyphotic angle changed from $15.35^{\circ}$ preoperatively to $12.03^{\circ}$ (postoperative one day), $13.64^{\circ}$ (three month), and $15.61^{\circ}$ (one year). Conclusion : Immediate pain relief was definite after VP in pathologic compression fracture of osteolytic spinal disease. Although VAS was slightly increased on one year follow-up, VP effect was maintained without significant change. These results indicate that VP could be a safe and effective procedure as a palliative treatment of the spinal tumor patients.

  • 낙동강 하구 일대 대심도의 연약지반 지역은 시간 의존적인 2차압밀 특성 등의 원인으로 예측보다 실제 과다한 침하가 발생하므로 설계 시점부터 2차압밀 특성을 고려한 예측기법의 필요성이 요구된다. 따라서 본 연구에서는 2,000일 이상의 장기 계측자료 분석과 1차원 이론, 탄소성, 점 탄소성의 수치해석을 수행하여 장기침하 특성을 분석하였다. 그 결과 1차원 이론, 탄소성 해석 모두 성토 높이와 연약층 깊이에 따른 뚜렷한 상관관계를 찾을 수 없었으나, 점 탄소성 해석 방법은 장기계측 결과와 아주 유사하게 침하를 예측하였다. 따라서 연구 대상 지역과 같은 대심도 지역에서 장기 침하 예측 시 점 탄소성 해석을 시공 전에 적용하면 2차압밀 침하 거동 특성을 미리 예측하여 시공 중 발생할 수 있는 공기 지연과 경제적 손실을 사전에 방지할 수 있을 것으로 판단된다.

영공(領空)과 우주공간(宇宙空間)의 한계(限界)에 관한 법적(法的) 고찰(考察) ("Legal Study on Boundary between Airspace and Outer Space")

  • One of the first issues which arose in the evolution of air law was the determination of the vertical limits of airspace over private property. In 1959 the UN in its Ad Hoc Committee on the Peaceful Uses of Outer Space, started to give attention to the question of the meaning of the term "outer space". Discussions in the United Nations regarding the delimitation issue were often divided between those in favour of a functional approach ("functionalists"), and those seeking the delineation of a boundary ("spatialists"). The functionalists, backed initially by both major space powers, which viewed any boundary as possibly restricting their access to space(Whether for peaceful or military purposes), won the first rounds, starting with the 1959 Report of the Ad Hoc Committee on the Peaceful Uses of Outer Space which did not consider that the topic called for priority consideration. In 1966, however, the spatialists, were able to place the issue on the agenda of the Outer Sapce Committee pursuant to Resolution 2222 (xxx1). However, the spatialists were not able to present a common position since there existed a variety of propositions for delineation of a boundary. Over the years, the funtionalists have seemed to be losing ground. As the element of location is a decisive factor for the choice of the legal regime to be applied, a purely functional approach to the regulation of activities in the space above the Earth does not offer a solution. It is therefore to be welcomed that there is clear evidence of a growing recognition of the defect inherent to such an approach and that a spatial approach to the problem is gaining support both by a growing number of States as well as by publicists. The search for a solution of the problem of demarcating the two different legal regimes governing the space above the Earth has undoubtedly been facilitated, and a number of countries, among them Argentina, Belgium, France, Italy and Mexico have already advocated the acceptance of the lower boundary of outer space at a height of 100km. The adoption of the principle of sovereignty at that height does not mean that States would not be allowed to take protective measures against space activities above that height which constitute a threat to their security. A parallel can be drawn with the defence of the State's security on the high seas. Measures taken by States in their own protection on the high seas outside the territorial waters-provided that they are proportionate to the danger-are not considered to infringe the principle of international law. The most important issue in this context relates to the problem of a right of passage for space craft through foreign air space in order to reach outer space. In the reports to former ILA Conferences an explanation was given of the reasons why no customary rule of freedom of passage for aircraft through foreign territorial air space could as yet be said to exist. It was suggested, however, that though the essential elements for the creation of a rule of customary international law allowing such passage were still lacking, developments apperaed to point to a steady growth of a feeling of necessity for such a rule. A definite treaty solution of the demarcation problem would require further study which should be carried out by the UN Outer Space Committee in close co-operation with other interested international organizations, including ICAO. If a limit between air space and outer space were established, air space would automatically come under the regime of the Chicago Convention alone. The use of the word "recognize" in Art. I of chicago convention is an acknowledgement of sovereignty over airspace existing as a general principle of law, the binding force of which exists independently of the Convention. Further it is important to note that the Aricle recognizes this sovereignty, as existing for every state, holding it immaterial whether the state is or is not a contracting state. The functional criteria having been created by reference to either the nature of activity or the nature of the space object, the next hurdle would be to provide methods of verification. With regard to the question of international verification the establishment of an International Satelite Monitoring Agency is required. The path towards the successful delimitation of outer space from territorial space is doubtless narrow and stony but the establishment of a precise legal framework, consonant with the basic principles of international law, for the future activities of states in outer space will, it is still believed, remove a source of potentially dangerous conflicts between states, and furthermore afford some safeguard of the rights and interests of non-space powers which otherwise are likely to be eroded by incipient customs based on at present almost complete freedom of action of the space powers.

  • Objectives : Although CTTH is one of the most common symptom in primary headache, the mechanism and treatment is not definite. The purpose of this study is to research about clinical characteristic and roentgenographic finding of the cervical spine in CTTH to determine relationship between the cervical spine and headache. Methods : This study was carried out on 93 patients with CTTH. By roentgenographic finding, they were classified into four groups - HNP, Spondylosis, Sprain, Normal. Then the HNP group was divided again into two groups - singer type and multiple type. Results: 1. Among 93 patients with CTTH, 69(74.19%) patients had abnormal cervical spine by roentgenographic finding. 2. There were HNP, spondylosis, sprain in abnormal roentgenographic finding. And a great majority of the patients were diagnosed as cervical sprain. 3. There were no significant difference between four groups on sex, weight, height, blood pressure, pulse, respiratory rate. But on ages, the HNP group showed the highest average while the sprain group showed the lowest. 4. The patients in HNP group had more frequent, severe pain, longer onset and higher onset-age than those of the other three group. 5. The patients in Multiple-type HNP group had severe pain, longer pain-duration, longer onset, more pre-symptoms and younger onset-age than those of the Single-type HNP group. Conclusions : A great majority of the patients with CTTH had abnormal cervical spines. Also, we found out that the worse the grade of HNP, heavier the level of headache.

  • 가로경관의 이미지는 가로공간 안에서 시각으로 느끼는 심리적인 인자와 물리적으로는 가로의 구조에 의해서 인지되는 인자의 복합적인 체험에 의한 것이다. 그러므로 가로경관의 이미지를 알아보기 위하여 가로를 구성하는 요소들 중에서 어떤 요소가 가로의 이미지를 만드는데 많은 영향을 주는지를 알아보기 위하여 가로공간을 심리적인 측면과 물리적인 측면에서 분석하고 평가하는 연구가 필요하게 되었다. 우선, 가로공간을 지역의 특성(상업지역, 업무지역, 복합지역)으로 나누어 분석하기 위해서 지역의 특성이 명확한 가로를 평가대상으로 선정하였다. 선정된 가로에서 느끼는 심리적 인자의 정보를 파악하기 위해서 설문방법을 사용하여 평가실험을 실시하였다 실험의 분석 결과, 가로경관의 이미지는 지역의 특성에 따라서 비슷한 성향을 갖고 있으며 가로의 이미지는 쾌적함과 번화함을 만드는 인자에 의해서 많은 영향을 받는다는 것을 인자분석의 결과로 알게 되었다. 인자분석에 의해서 구분된 가로의 이미지 중에서 번화함이 있는 가로와 번화함이 없는 가로의 집단은 가로의 물리적 구성요소 면에서 각각 어떤 차이가 있어서 상반된 이미지를 갖는지를 알아보기 위해 가로의 구성 요소를 중심으로 판별분석을 실시하여 두 집단 간의 차이를 알아보았다. 분석 결과 번화함이 있는 가로와 번화함이 없는 가로의 이미지는 물리적 구성요소 중에서 가로 폭, 보도 폭과 차도 폭의 비율, 건물의 높이와 가로 폭의 비율, 그리고 식재율 등의 차이가 가로의 이미지가 상반되게 느끼게 하는데 많은 영향을 미친다는 것을 알게 되었다. 이 연구는 어떤 종류의 가로라도 가로의 이미지를 보다 명확하게 분석하고 평가할 수 있게 하였으며, 번화한 이미지를 갖는 가로를 만들기 위한 물리적 인 요소의 구성방법도 알 수 있게 하였다. 이렇게 함으로써 지역의 활성화하기 위하여 가로의 이미지를 분석하고 번화함이 있는 가로를 조성하기 위한 자료를 만드는 방법으로 많이 활용될 것으로 사료된다.
