1. This thesis aims at analyzing the characteristics of the demarcation line of the administration areas in Korea by reviewing the history and background of how it was drawn and at the same time at exploring ways of correcting factors contributing to problems and ineffectiveness of administration. In order to collect data of opinions on this matter from officials actually assigned to the counties and their sub-level administration areas where administration is bifurcated in two separated blocks of areas, irrespective of the administrative efficiency and convenience of the populace in the areas, we selected eight kuns of this nature and sent questionaires to 488 chiefs and leading officials of kuns, myuns and villages. A total of 237 persons, 48.6% out of 488 responded. This data proved to be very expedient and instrumental in carrying out this study. 2. One of the characteristics of the demarcation line of administration areas is that it is drawn on the basis of natural conditions such as the extention of mountains, meandering lines of rivers, the formation of the community, traditional reasons, and so forth rather than on the theoretical as well practical backgrounds imbued with administrative philosophy, which seeks for rational and balanced development of a whole community with two factors in mind: the principle of spatial division as an administrative skill and the principle of spatial harmony for balanced division of administration zones. However, it is true that a large number of local inhabitants have felt inconveniences due to the boundary lines being zigzag or meandering. When we surveyed on the frequency of going to market as an indicator of economic activities of the people living along the boundary lines, it is found that almost 77.6% of the people questioned answered that they were going to markets located in the neighboring kun rather than those in their own administration zones. The factors that lead to choosing markets are usually two: one is spatial distance and the other is the peoples norm of life. Although the nature of the responses may vary according to where people live within the divided block of the administration area, a total of 86.6% of the questioned expressed their hope that the boundary lines would be straightened. This reflects their wishes of improving the efficiency of local administration and convenience of living for effectiveness of the administration cantrol. For example, state boundary lines of the U.S and Australia belong to the theoretical type is whereas sung boundary lines of China and kun(county) demarcation lines of Korea belong to the natural condition (or setting) type. Especially, some of administration demarcation lines of Korea have been zigzay so that one kun is divided into two or more separate blocks of areas as the result of city administration areas within the kun becoming enlarged. There are eight cases of this nature in Korea. 3. Our survey which was conducted to discover in part the extent of awareness of such bifurcation or division by the inhabitants living in the divided zones, showed that only 83.4% of those who responded said that they had knows the fact and the remaining 15.5% were quite unaware of the fact until they came to realize it upon reading our questionaire. This extent of unawareness means that local ranking administration leaders did not pay much attention to the effect of the local administration with respect to the boundary lines. 4. Speaking from the above finding, we are to propose that irrational factors related to the present administration demareation lines be corrected and improved for the following reasons: 1) To enhence the efficiency of administration, 2) To reestablish the system of utilization of resources 3) And finally to enlarge the integrated potentials of various social dynamics. We hope that efforts will be made to straighten administration demarcation lines as far as possible, taking into consideration the opinions and wishes of the people living in the affected areas and zones so that directions of development and improvement on this matter may be effectively explored. At the same time we propose the establishment of long range policies with a view of eliminating disparity in the development between the regions, by implementing necessary measures for development of local cities.

Yang, Jin Seo,Cho, Yong Jun,Kang, Suk Hyung,Choi, Hyuk Jai The Korean Neurosurgical Society 2014 Journal of Korean neurosurgical society Vol.55 No.2

Objective : The restless legs syndrome (RLS) is a common disorder affecting up to 5% to 15% of the general population, in which the incidence increases with age, and includes paresthesia in the legs. The purpose of this study is to investigate the incidence of RLS in spine center and to review clinical manifestations of this syndrome and its current treatments. Methods : Over a period of a year, retrospective medical record review and lumbar magnetic resonance images were performed on 32 patients with RLS in spine clinic who were diagnosed by National Institutes of Health criteria. Affected limbs were classified as five. Two grading systems were used in the evaluation of neural compromises. Results : The incidence of RLS was 5.00% (32/639). There were 16 males (50%) and 16 females (50%). The median age at diagnosis was 55.4 years (range, 25-93 years). There are no correlation between the affected limbs of RLS and neural compromises on the lumbar spine. Conclusion : The RLS is a clearly common neurologic disorder of the limbs, usually the legs. The awareness of this syndrome can help reduce diagnostic error; thereby, avoiding the morbidity and expense associated with unnecessary studies or inappropriate treatments in RLS patients.

Pure Intramuscular Osteolipoma

Yang, Jin Seo,Kang, Suk Hyung,Cho, Yong Jun,Choi, Hyuk Jai The Korean Neurosurgical Society 2013 Journal of Korean neurosurgical society Vol.54 No.6

Ossified lipoma or osteolipoma are rarely reported. It is defined as a histologic variant of lipoma that has undergone osseous metaplasia. Osteolipoma presents with a dominant osseous component within a lipoma. We report a case of a histologically confirmed osteolipoma on the nuchal ligament independent of bone. The patient was a 51-year-old female who presented with a 5-year history of a painless, progressively enlarging mass on the posterior neck. Computed tomography and magnetic resonance imaging showed a circumscribed mass compatible with fat between the C2 and C6 spinous processes with a large calcified irregular component. The mass with dual components was totally removed under general anesthesia and no recurrence was observed after 6 months of follow-up. We also reviewed the clinicopathologic features of previously reported osteolipomas in the literature and suggest that although osteolipoma is a rare variant of lipoma, it should be considered in the differential diagnosis when a lipoma of the posterior neck mixed with a bony component is encountered.

Rapid Progression of Solitary Plasmacytoma to Multiple Myeloma in Lumbar Vertebra

Yang, Jin Seo,Cho, Yong Jun,Kang, Suk Hyung,Choi, Hyuk Jai The Korean Neurosurgical Society 2013 Journal of Korean neurosurgical society Vol.54 No.5

The prognosis of solitary plasmacytoma varies greatly, with some patients recovering after surgical removal or local fractional radiation therapy, and others progressing to multiple myeloma years later. Primary detection of progression to multiple myeloma is important in the treatment of solitary plasmacytoma. There have been several analyses of the risk factors involved in the early progression to multiple myeloma. We describe one case of solitary plasmacytoma of the lumbar vertebra that was treated with surgical decompression with stabilization and additional radiotherapy. The patient had no factors associated with rapid progression to multiple myeloma such as age, size, immunologic results, pathological findings, and serum free light chain ratio at the time of diagnosis. However, his condition progressed to multiple myeloma less than two months after the initial diagnosis of solitary plasmacytoma. We suggest that surgeons should be vigilant in watching for rapid progression to multiple myeloma even in case that the patient with solitary plasmacytoma has no risk factors for rapid progression to multiple myeloma.

Yang, Jin Seo,Choi, Hyuk Jai,Cho, Yong Jun,Kang, Suk Hyung The Korean Neurosurgical Society 2014 Journal of Korean neurosurgical society Vol.55 No.4

Objective : To evaluate the incidence of postsurgical sensory complications in patients with scalp masses and classify the locations of them from a surgical standpoint according to anatomical considerations. Methods : A total of 121 patients who underwent surgery for scalp mass were included in this study. The authors reviewed medical records and preoperative radiologic images. We investigated the complications related to sensory changes after procedure. Enrolled patients have been divided into three groups. Group A included patients with tumors above the superior nuchal line (SNL), Group B with tumors within the trapezius muscle area and patients who had tumors on the lateral trapezius muscle area were assigned to Group C. We compared the incidence related to postoperative sensory complications and summarized their additional treatments for these with clinical outcome. Results : There were 12 patients (10%) with sensory complications related on the mass excision site (Group A : 1 patient, Group B : 2 patients, Group C : 9 patients). Six patients were affected with lesser occipital nerve (LON), 2 patients on greater occipital nerve (GON) and 4 patients on GON and LON. Over 6 months after surgery, two of the twelve patients with sensory complications did not have complete recovered pain in spite of proper medications and local chemical neurolysis with 1.0% lidocaine and dexamethasone. Conclusion : Occipital neuropathy should be considered as a complication related excision of scalp mass. The sensory complications are more frequent in Group C because of the anatomical characteristics of the occipital nerves and there were no statistical difference for other variables.

본 논문에서는 소형 위성 카메라의 영상안정화를 위해 진동외란 보상 및 궤도상 광학정렬이 가능한 능동형 광학 보정장치의 설계에 대해 연구하였다. 능동형 광학 보정장치는 초점면부 보정장치와 부경 보정장치로 이루어져 있다. 초점면부 보정장치는 영상센서에 유입되는 진동 외란을 초점면부에서 직접 보상하는 장치이다. 또한 부경 보정장치는 초점면부 보정장치와 협력하여 궤도상에서 능동적으로 광학정렬을 수행할 수 있는 장치이다. 본 논문에서는 해상도 1 m급 소형 위성에 적용 가능한 능동형 광학 보정장치 설계를 위해 소형 고해상도 위성 카메라의 요구도를 분석하고, 진동 외란 보상과 궤도상 광학정렬이 능동적으로 가능하도록 초점면부 보정장치와 부경 보정장치의 요구도를 선정하였다. 선정된 요구도를 기준으로 본 연구에서 설계된 능동형 광학 보정장치는 초점면부에서 진동외란 보상 및 초점조절, 부경에서 틸트 및 디스페이싱 보상이 가능하므로 독립적으로 5축 제어가 가능한 시스템이다. This paper describes the design of the active optical compensation movements(at focal plane, secondary mirror) for the image stabilization of a small satellite camera. The movements can correct optical misalignment on-line and directly compensate vibration disturbances in the focal plane. Since the devices are installed inside the space camera, it has an remarkable advantage to deal with the structural deformation of a space camera effectively. In this paper, the requirements of the active optical compensation movements for 1m GSD small satellite camera have been analyzed. Based on the established requirements, the design of the active compensation movements have been conducted. The designed active optical compensation system can control 5 axes movements independently to compensate micro-vibration disturbances in the focal plane and to refocus the optical misaligned satellite camera.

Coil Embolization in Ruptured Inferior Thyroid Artery Aneurysm with Active Bleeding

Lee, Sung Ho,Choi, Hyuk Jai,Yang, Jin Seo,Cho, Yong Jun The Korean Neurosurgical Society 2014 Journal of Korean neurosurgical society Vol.56 No.4

We present a unique experience of urgent parent arterial embolization for treatment of an aneurysm of the inferior thyroid artery (ITA) that bled during tracheostomy. The event happened to a 69-year-old female patient with subarachnoid hemorrhage and hospital-acquired pneumonia that required tracheostomy. Abrupt and massive bleeding developed during the procedure, and the source could not be identified. Under manual compression, angiography revealed an 8-mm aneurysm that arose from the inferior thyroid artery. The superselected parent artery of the aneurysm was successfully occluded with a single pushable coil. The patient's postoperative course was uneventful.
