  • This study compares the strength properties of Jumchi-Hanjis dyed with 70% and 100% persimmon juice concentrations and undyed Jumchi-Hanjis. The Juumchi-Hanjis were made from Dakjis (mulberry papers), which were mixed with different ratios of fibers from paper mulberries originating in Korea and Thailand, including wood pulp from Canada. Research results showed that tensile, wet tensile, and bursting strengths of Jumchi-Hanjis dyed with 70% concentration were higher than those of undyed Jumchi-Hanjis. However, the tearing strengths of the dyed Jumchi-Hanjis were lower than those of undyed Jumchi-Hanjis. The wet tensile strengths of Jumchi-Hanjis dyed with 100% concentration were higher than those of dyed with 70% concentration. The increase and decrease of tensile, tearing, and bursting strengths depending on persimmon juice dyeing differed as per the mixing ratio of the raw materials of Jumchi-Hanjis. Dyeing with 100% persimmon juice concentration tends to be more useful than 70% to increase the tensile (MD) and wet tensile strengths of Jumchi-Hanjis containing only Korean mulberry fibers (90%) and wood pulp (10%) as raw materials. Dyeing with 100% concentration tends to be less useful than 70% to increase the tensile, tearing and bursting strengths of Jumchi-Hanjis with high proportions (90% or 60%) of mulberry fibers from Thailand.

  • 인간게놈프로젝트의 시작과 함께 그 사회적 부작용의 하나로 거론되었던 '유전정보 차별'의 문제가 아직 우리나라에서 크게 부각된 적은 없다. 그러나 2016년 6월 30일부터 시행된 "생명윤리 및 안전에 관한 법률"이 의료기관이 아닌 유전자검사기관의 유전자검사를 예외적으로 허용하자, 국내의 한 보험회사가 신규 암보험 가입자를 대상으로 DTC 유전자 검사를 별도의 무료 서비스로 제공하겠다고 하여 유전자 검사와 관련된 사회적 변화를 실감케 한 바 있다. 정밀의료가 의료의 새로운 표준으로 성큼 다가온 현 시점에서 유전정보 차별에 관한 규율은 더 이상 미룰 수 없는 문제가 되었다. 우리나라는 생명윤리법 제46조, 제67조에서 유전정보를 이유로 한 차별의 금지와 그 위반행위에 대한 벌칙을 규정하고 있지만, 이러한 광범위한 원칙 규정만으로는 보험, 고용 등 구체적인 유전정보 활용 영역에서의 문제점들을 충분히 해결할 수 없다. 미국, 캐나다, 영국, 독일은 상이한 방식으로 유전정보 차별의 문제를 다루고 있다. 미국의 "Genetic Information Non-Discrimination Act"의 경우, 건강보험과 관련된 부분은 기존의 법에 유전정보 차별금지에 관한 내용을 추가하는 형식을 취하고 있다. 또 개인과 그 가족의 유전자 검사 결과 외에 '가족력'까지 포함하여 유전정보의 범위를 매우 넓게 규정하고 있다. 캐나다는 2017년 비교적 최근에 법을 제정하였는데, 보험과 고용 외에 '상품이나 서비스의 거래'에까지 적용범위를 확장하고 있다. 영국은 유전자 검사 중 '개인의 예측적 유전자 검사'에 대해서만 다루고 있는데, 보험의 경우 영국정부와 보험협회의 '협약'을 통해 유전정보의 활용을 2019년까지 유예하는 방식으로 규율하고 있고, 고용의 영역은 ICO가 만든 'Employment Practices Code(2011)'가 기준으로 활용되고 있다. 독일은 유전자 검사에 관한 법 "Gesetz ${\ddot{u}}ber$ genetische Untersuchungen bei Menschen"에서 고용과 보험에서의 유전자 검사 및 그 결과 제출 요구의 원칙적 금지를 규정하고 있다. 이와 같이 각 나라마다 규율형식, 적용범위 뿐만 아니라 규율의 실효성에 대한 평가도 매우 상이하다. 이러한 점에 비추어 보았을 때 우리나라의 유전정보 차별에 관한 규제 역시 관련 규정의 검토, 전문가 집단의 참여 및 이해관계자의 협력을 통해 여러 규제안의 장 단점을 충분히 검증한 후 입법의 단계로 나아가는 것이 바람직할 것이다.

  • Purpose : Resection of the epileptogenic zone in the parietal and occipital lobes may be relevant although only few studies have been reported. Methods : Eight patients with parietal epilepsy and nine patients with occipital epilepsy were included for this study. Preoperatively, all had video-EEG monitoring with extracranial electrodes, MRI, 3D-surface rendering of MRI using Allegro(ISG Technologies Inc., Toronto, Canada), and PET scans. Sixteen patients underwent invasive recording with subdural grid. Eight had parietal resection including the sensory cortex in two. Seven had partial occipital resection. Two underwent total unilateral occipital lobectomy. The extent of the resection was made based mainly on the data of invasive EEG recordings, MRI, and 3D-surface rendering of MRI, not on the intraoperative electrocorticographic findings as usually done. During resection, electrocortical stimulation was performed on the motor cortex and speech area. Results : Out of eight patients with parietal epilepsy, three had sensory aura, two had gustatory aura, and two had visual aura. Six of nine patients with occipital epilepsy had visual auras. All had complex partial seizures with lateralizing signs in 15 patients. Four had quadrantopsia. One had mild right hemiparesis. Abnormality in MRI was noticed in six out of eight parietal epilepsy and in eight out of nine occipital epilepsy. 3D-surface rendering of MRI visualized volumetric abnormality with geometric spatial relationships adjacent to the normal brain, in all of parietal and occipital epilepsy. Surface EEG recording was not reliable in localizing the epileptogenic zone in any patient. The subdural grid electrodes can be implanted on the core of the structural abnormality in 3D-reconstructed brain. Ictal onset zone was localized accurately by subdural grid EEGs in 16 patients. Motor cortex in nine and sensory speech area in two were identified by electrocortical stimulation. Histopathologic findings revealed cortical dysplasia in 10 patients ; tuberous sclerosis was combined in two, hamartoma and ganglioglioma in one each, and subpial gliosis in six. Eleven patients were seizure free at follow-up of 6 months to 37 months(mean 19.7 months) after surgery. Seizures recurred in two and were unchanged in one. Six produced transient sensory loss and one developed hemiparesis and tactile agnosia. One revealed transient apraxia. Two patients with preoperative quadrantopsia developed homonymous hemianopsia. Conclusion : This study suggests that surgical treatment was relevant in parietal and occipital epilepsies with good surgical outcome, without significant neurologic sequelae. Neuroimaging studies including conventional MRI, 3Dsurface rendering of MRI were necessary in identifying the epileptogenic zone. In particular, 3D-surface rendering of MRI was very helpful in presuming the epileptogenic zone in patients with unidentifiable lesion in the conventional MRI, in planning surgical approach to lesions, and also in making a decision of the extent of the epileptogenic zone in patients with identifiable lesion in conventional MRI. Invasive EEG recording with the subdural grid electrodes helped to confirm a core of the epileptogenic zone which was revealed in 3D-surface rendered brain.

  • 본 연구에서는 치과용 디지털 색상 분석기기 중 하나인 Shadescan (CYNOVAD, Montreal, Canada)의 색상 분석의 정확성과 재현 능력을 평가하였다. 균일한 치아 배열을 가진 20대 성인 남자 8명과 여자 8명의 상악 인상을 고무인상제 (Exaflex, GC, Japan)를 이용하여 채득하고, 인상에 A2 색상의 임시 크라운 제작용 자가중합형 레진을 주입하여 치아 모델을 완성하고, ShadeScan을 이용해 각 치아의 영상을 얻어 컴퓨터의 ShadeScan 프로그램으로 분석하였다. 그리고 측정 결과의 재현 능력를 평가하기 위해 2개의 치아 모델을 임의로 선택하여 각 치아마다 10회의 색상 측정을 시행하여 분석 결과를 비교하였다. 또한 분석된 영상의 동일 shade 간의 색차를 확인하기 위해 광중합 복합레진인 Gradia Direct (GC, Tokyo, Japan)의 shade guide의 CIE $L^*a^*b$ 값을 백색과 흑색 배경판 상에서 spectrophotometer (Spectrolino, GretagMacbeth, USA)로 측정하고, ShadeScan에 의해 동일한 shade로 분석된 shade guide간의 색차를 계산하여 다음의 결과를 얻었다. 모든 치아에서 모델 제작 재료와 동일한 A2 색상으로 분석된 경우는 없었으며, 개개의 치아에서 전체 순면이 동일한 색상으로 분석된 예는 없었다. 또한 동일한 치아군에서 치아의 크기, 형태, 순면의 굴곡 등에 따라 서로 다른 색상 분포를 보였다. 재현성 평가에서 각 치아의 중앙부는 비교적 일정한 재현성을 보였으나, 절단부와 주변 부위는 재현성이 낮았으며, 동일한 shade로 분석된 shade guide 간에는 3 이상의 색차 (${\Delta}E^*$)를 보였다. 이상의 결과는 치과용 디지털 색상 분석기기는 비록 높은 재현 능력은 가지고 있지만 정확성에 오류가 있음을 시사하며, 따라서 이러한 기기를 이용한 색상 분석 시 좀 더 세밀한 주의와 다른 방법의 추가 사용이 필요하리라 사료된다.

  • In this paper, state of exploitation of world fishery resources after 10 years under the new regime in the sea, called the era of exclusive economic zone (EEZ) expending up to a 200 nautical miles from coastal line, was reviewed to determine effect from establishing EEZ in the world fishery production and its export/import volume based on the fishery statistics annually published by the Food and Agriculture Organization (FAO) of United Nation. The world total production from marine living resources had a trend showing a waned increase during 1970's when most of coastal states were translated into the reality of EEZ. From mid-1980's onwards, it increased rapidly, reaching about 85 million tons . Such increase in production was basically from the Pacific Ocean, accounting for more than 60% of the world total production. Fishing areas where showed increase in the production after the new regime in the sea were the southwestern Atlantic (FAO area 41) , the eastern Indian (FAO area 57) and the whole fishing areas in the Pacific except the eastern central Pacific (FAO area 77). Increase in the production from distant-water fishing countries came from the regions of the southwest Atlantic (FAO area 41) and the southwest Pacific (FAO area 81) . The production from coastal states was up from the regions of the eastern Indian (FAO area 57) , the northwest and northeast Pacific (FAO areas 61 and 67) and the southeast Pacific (FAO area 87) . It was likely that the exploitation of the fishable stocks was well monitored in the areas of the northwest Atlantic (FAO area 21) , the eastern central Atlantic (FAO area 34) and the northeast Pacific (FAO area 67) through appropriate management measures such as annual harvest level, establishment of total allowable catch etc. The marine fisheries resources that have made contribution to the world production, despite expansion of 200 EEZ by coastal states, were sardinellas, Atlantic cod, blue whiting and squids in the Atlantic Ocean : tunas which mainly include skipjack, yellowfin and bigeye tuna, croakers and pony fishes in the Indian Ocean : and sardine, Chilean pilchard, Alaska pollock, tunas (skipjack and yellowfin tuna) , blue grenadier and blue whiting including anchoveta in the Pacific Ocean. It was identified that both fishery production and its export since introduction of the new regime in the sea were dominated by such coastal states as USA, Canada, Indonesia, Thailand, Mexico, South Africa and Newzealand. But difficulties have been experienced in the European countries including Norway, Spain, Japan and Rep. of Korea. Therefore, majority of coastal states are unlikely to have yet undertaken proper utilization as well as rational management of marine living resources in their jurisdiction during the last two decades. The main target species groups which led the world fishery production to go up were Alaska pollock, cods, tunas, sardinellas, chub and jack mackerel and anchoveta. These stocks are largely expected to continue to contribute to the production. The fisheries resources which are unexploited, underexploited and/or lightly exploited at present and which will be contributed to the world production in future are identified with cephalopods, Pacific jack mackerel and Atlantic mackerel, silver hake including anchovies. These resources mainly distribute in the Pacific regions, especially FAO statistical fishing areas 67, 77 and 87. It was likely to premature to conclude that the new regime in the sea was only in favour of coastal states in fishey production.

  • Objective: In the winter of 2002, severe acute respiratory syndrome(SARS) began to spread throughout the world. More than 5,000 cases were reported in China, including over 1,700 cases in Hong Kong Special Administrative Region(Hong Kong SAR). The total number of cases reported from Canada and Singapore was more than 200. The total number of SARS cases world-wide reached 8,437 with incidences in 29 counties. Mortality from SARS is estimated at $10{\sim}12%$. When the SARS outbreak occurred in China, the State Administration of Traditional Chinese Medicine of China immediately initiated clinical research projects on the use of integrated herbal medicine and Western medicine for treating SARS. and, in Hong Kong SAR, research on the use of herbal medicine for the prevention and treatment of SARS. Reports were released during convalescence. The objective of this study is to overview twelve clinical SARS reports of WHO on the treatment of SARS with herbal medicine and evaluate the efficacy and safety of treatment of SARS with herbal medicine, and further to share experiences and knowledge of the treatment of SARS. Methods: Twelve clinical reports about SARS from the WHO were selected, overviewed and evaluated for efficacy and safety of treatments of SARS. Results and Conclusion: Twelve clinical reports about SARS showed that the integrated treatment may have advantages, and the advantages are reflected in the following findings: Firstly, herbal medicine is not targeted only at a specific etiology or a certain pathological link, but also at the pathological status of the patients at that particular time. Therefore, comprehensive readjustment was made through various angles, targets and channels to restore the balance of the body. Secondly, there are advantages in the differentiation of the disease and the treatment. Based on the various symptoms, herbal medicine enables the physician to adopt the most suitable principle, provide individual treatment, and to administer medicine in accordance with the actual process and nature of the illness. Thirdly, there are advantages in the results of the treatment; herbal medicine can relieve symptoms, promote absorption of lung inflammation, improve the degree of blood oxygen saturation, regulate immunological functions, reduce the required dosage of glucocorticoid and other Western medicines, and reduce case fatality rate, in addition to lowering the cost of treatment.

  • Respiratory Syncytial virus (RSV) is an important cause of acute lower respiratory tract infections in human, with infants and young children being particularly susceptible. In the temperate zones, sharp annual outbreaks of RSV occur during the colder months, in both the northern and the southern hemisphere. RSV is unusual in that it can repeatedly reinfect individuals throughout life and infect babies in the presence of maternal antibody. RSV isolates can be divided into two subgroups, A and B, on the basis of their reactions with monoclonal antibodies, and the two subgroups are also distinct at the nucleotide sequence level. The specific diagnosis of RSV infection was best made by isolation of virus in tissue culture, identification of viral antigen, or by specific serologic procedures. Recently, rapid detection of RSV and analysis of RSV strain variation became possible by development of methods of reverse transcription and polymerase chain reaction amplification. In this study, to determine the genetic diversity of RSV found in Korea, 173 bp and 164 bp spanning selected regions of the RSV F and SH genes were enzymatically amplified and sequenced, respectively. Eight for F gene and three for SH gene were detected in 66 nasopharyngeal swap samples tested. Two major antigenic subgroups, A and B were confirmed from Korean samples (seven for subgroup A and one for subgroup B). At the nucleotide level of the F gene region, Korean subgroup A strains showed 95-99% homologies compared to the prototype A2 strain of subgroup A and 93-100% homologies among Korean subgroup A themselves. For the SH gene region, Korean subgroup A strain showed 97.5% homology compared to the prototype A2 strain of subgroup A, and Korean subgroup B strain showed 97% homology compared to the prototype 18537 strain of subgroup B. Most of base changes were transition and occured in codon position 3, which resulted in amino acid conservation. Using the maximum parsimony method, phylogenetic analysis indicated that Korean RSV strains formed a group with other RSV strains isolated from the United States, Canada, the Great Britain and Australia.

  • 해상 HNS 유출사고 대응 교육훈련체계의 국내 및 외국(미국, 캐나다, 호주, 영국) 현황을 살펴보고, 국내 체계와 외국 체계 간의 비교를 통하여 국내의 교육훈련체계 개선방안에 대한 연구를 수행하였다. 그 결과, 국내의 민간 교육훈련기관이 거의 전무한 상태에서 외국의 기관들에 비하여 활성화되지 못하였고, 국내의 해상 HNS 관련 교육훈련이 정부 주도 하에 획일적으로 이루어지고 있는 실정이었다. 또한 국내의 교육훈련기관인 해양경찰교육원과 해양환경교육원 간에는 교육대상자, 교육기간 등에서 차이가 있었다. 국내의 해상 HNS 관련 교육과정이 외국의 교육과정에 비하여 단순한 편이었고, 교육기간도 상대적으로 짧았으며, 국제해사기구 HNS 모델코스의 2가지 과정(운영 수준 및 관리자 수준)을 수용하지 않고 있었다. 국내 해상화학사고 대응 교육훈련체계를 개선하기 위한 방안을 단기적 측면과 중 장기적 측면으로 나누어 제시하였다. 단기적 측면에서, 해양경찰교육원과 해양환경교육원은 각자 독립적으로 운영하는 현행의 이원적 체계를 유지하면서 두 기관이 공동으로 참여하는 HNS교육훈련운영협의체(가칭)를 설립하는 방안을 제시하였고, 중 장기적 측면에서는, 해양경찰교육원 HNS 담당부서와 해양환경교육원 HNS 담당부서를 통합하여 국제경쟁력을 갖춘 일원적 체계인 국가해상HNS방제교육훈련기관(가칭)으로 변경 확대하는 방안을 제시하였다.

  • In recent years, riparian buffer system has been known as one of the effective best management practices. However, establishment of riparian buffer system in aspect of plant species and its position in the riparian buffer zone has not been investigated due to lack of efficient evaluation method for the analysis of water quality improvement with established riparian buffer system. To solve this problem, the SWAT-REMM prototype was developed by the researchers in Canada. But, SWAT-REMM model can not consider the $NO_3-N$ load into riparian buffer system through subsurface flow. Thus to solved this problem, Fortran code of SWAT-REMM model was modified. This modified SWAT-REMM system was applied to the Bonggok watershed. Three riparian buffer scenarios, 15 m, 10 m, 5 m width for tree and grass, were made to evaluate the effects of riparian buffer system on water quality improvement. Reduction efficiency of T-N by riparian buffer system of 15 m wide was the greatest (6 ~ 37%, depending on subwatershed characteristics) among 3 scenarios. It indicates that the reduction efficiency of T-N load has increasing-tendency, as buffer width increasing. The results obtained from the analysis showed that wide buffer zones are found to be more effective in reducing non-point pollutant than narrow buffer zones in the riparian buffer zone system. Hence, the SWAT-REMM model could be efficiently used for evaluation and design the most effective riparian buffer systems to reduce pollutant loads to the watershed although many limitations still exist in SWAT-REMM model.
