외국인 근로자들은 90년대 들어 그 수가 급격히 증가하였고, 각종 제조업이나 3D업종에서 중요한 위치를 차지하게 되었다. 이러한 상황에서 정부는 산업기술 연수생이라는 제도를 통해서 편법적으로 외국인 근로자를 수입하는 정책을 유지해왔었다. 산업기술 연수생은 불분명한 신분을 가진 외국인 근로자들에 대한 차별과 인권 유린으로 수많은 사업장 이탈자를 만들었다. 2004년 8월에 도입된 '고용허가제'는 그 동안의 국내 외국인력 정책을 그 근본에서부터 바꿨다는 점에서 그 의의가 있다. 고용허가제의 도입은 제조업 및 서비스업 뿐만 아니 라 건설업에도 많은 영향을 미칠 것으로 기대된다. 이에 본 연구에서는 외국인 근로자와 고용허가제의 정보를 바탕으로 고용허가제가 건설현장에 미치는 인건비, 작업품질 및 태도, 노동력 수급, 의사소통에 대해 현장관리자와의 설문조사를 실시하였다. 도출된 현장관리자들의 인식을 통해 향후 건설업에서의 부작용을 제거하고 대응방안을 제시하고자 한다. The number of domestic foreign worker increased rapidly In the 90s, and Domestic foreigner worker occupied important position in the various manufacturing industries or 3D types of business. In these situation, Government had kept policy that import foreigner worker through system for industrial technology trainee. Distinction and outrage about foreign worker who have ambiguous social position made many place of business seceders. At August,2004 a new introduced employment permit system has great significance that has fundamentally and drastically changed current foreign immigrant policy from the basis. Introduction of Employment permit system is expected to affect much effects to construction industry as well as manufacturing industry and service industry. In this research, with foreign worker and information of employment permit system investigated personnel expenses, work quality and attitude, labor power supply and demand, communication to affect in construction field at employment permit system through questionnaire with field administrators. This research will remove a side effect in construction industry through administrators' awareness and wish to present confrontation way.

Purpose: To report a case of Serratia marcescens keratitis presenting as radial keratoneuritis. Case summary: A 15-year-old female who wore cosmetic and orthokeratology contact lenses but performed inadequate lens care visited our clinic with severe pain and visual disturbance in her left eye. On slit lamp examination, central corneal epithelial defect and stromal infiltration with radial keratoneuritis were observed. Based on clinical findings and past history, Acanthamoeba keratitis was highly suspected. The patient was treated with topical chlorhexidine 0.02% (Sigma-Aldrich Co., MO, USA) and moxifloxacin 0.5% (Vigamox<sup><font size=`2`>Ⓡ</font>, Alcon, TX, USA) per hour with 200 mg of oral itraconazol (Sporaone<sup><font size=`2`>Ⓡ</font>, LG, Seoul, Korea) once a day. Symptoms and corneal lesions did not improve after three days. After Serratia marsenscens was isolated from her contact lenses and solution, topical chlorhexidine 0.02% was discontinued, and intravenous ceftazidime (Tazime<sup><font size=`2`>Ⓡ</font>, Hanmi, Seoul, Korea) and fortified ceftazidime (50 mg/mL) eye drop was added. The corneal lesion dramatically improved, and after six months of follow-up, best-corrected visual acuity was 20/20 in the affected eye. Conclusions: Radial keratoneuritis can present not only in Acanthamoeba keratitis, but also in Serratia marsenscens keratitis. Confirmation of the isolated organism is useful when treating radial keratoneuritis. J Korean Ophthalmol Soc 2014;55(9):1380-1383

In this study, life needs included in the IEP data of students with intellectual disabilities were comprehensively analyzed in the order of life domain, sub domain and specific task skills according to the life-centered career education model of Brolin(1993), a transition assessment tool, and selected restaurant skill as the topic of the course. Also in order to set learning goals on the course topic, content elements in each domain and level of social subject in special education basic curriculum, closely related to specific task skills analyzed by the model of Brolin(1993) mentioned earlier, were extracted and supplemented according to the context of course topic. Thereupon in this study, search of restaurants, ordering of food and dining skill were selected as learning goals on the course topic. In addition, this study designed practically applicable teaching methods and assessment of course topic and learning goals, which had been selected based on the transition education program by Kim, Young-Jun and Kim, Jin-Ho(2010). That is, ecological analysis on the community in which the course topic and learning goals were being carried out was conducted with task analysis on each learning goal on the course topic. Various teaching and learning strategies were configured with process-focused performance assessment methods at the level of integral intervention package. Furthermore in an attempt to functionally intensify and develop the selected course topic and learning goals, follow-up extension activities were devised through intra -subject and inter-subject integration.

The purpose of this study was to study the histopathological correlation between the use of platelet-rich plasma and enamel matrix protein used in conjunction with xenograft. compared to a control group with regards to bone regeneration at the grade III furcation area in beagle dogs. Control group was treated with bovine derived bone $powder(Biocera^{(R)})$, and experimental I group was treated with bovine derived bone powder and Platelet-rich plasma and experimental II group was treated with bovine derived bone powder and Enamel matrix $protein(Emdogain^{(R)})$. The regeneration rate of bone formation was observed and compared histopathologically at 2. 4, and 8 weeks after surgery. The results were as follows: 1. In control group and both experimental groups. inflammatory cells were observed but, new bone formation wasn't. 2. In control group, new cementum on the notch was found in 4 weeks, less mature periodontal ligament when compared to that of experimental group was found and cementum formation was great but, regeneration couldn't be seen in 8 weeks. 3. Experimental I group. new bone formation in the area adjacent to alveolar bone and graft material surrounded by more dense connective tissue were found in 4 weeks. New bone formation up to crown portion was found and periodontal ligament was aligned functionally and cementum more mature. 4. Experimental II group, new bone formation was found under the defect area in 4 weeks and new bone formation around graft material in 8 weeks, too, and there were a number of fibroblasts, blood vessels, acellular cementum, which was less mature when compared to that of experimental I group, and dense collagen fiber like which normal periodontal ligament has in periodontal ligament of experimental II group in 8 weeks. 5. As a result of histologic finding, bone formation rate were 18.0${\pm}$7.87%(control group), 34. 05${pm}$7.25%(experimental I group), 19.33 ${pm}$5.15%(experimental II group) in 4 weeks and 21.89${pm}$1.58%(control group), 38.82${pm}$3.2(experimental I group), 37.65${pm}$9.22%(experimental II group) in 8 weeks. 6. Statistically significant ratio of bone formation was observed in experimental I group in 4 weeks and in experimental II group in 8 weeks. When experimental I group was compared to experimental II group, the ratio of bone formation in experimental I group was higher than that in experimental II group in 4 weeks(p<0.05). This results suggest that platelet-rich plasma showed more new bone formation than enamel matrix protein within 4 weeks. And use of enamel matrix protein in the treatment of periodontal bone defects starts to enhance regeneration after 8 weeks in beagle dogs.

An acceleration of climate change in recent years has led to increased attention towards 'blue carbon' which refers to the carbon captured by the ocean. However, our comprehension of marine ecosystems is still incomplete. This study classified and analyzed global marine eco-provinces using k-means clustering considering carbon cycling. We utilized five input variables during the past 20 years (2001-2020): Carbon-based Productivity Model (CbPM) Net Primary Production (NPP), particulate inorganic and organic carbon (PIC and POC), sea surface salinity (SSS), and sea surface temperature (SST). A total of nine eco-provinces were classified through an optimization process, and the spatial distribution and environmental characteristics of each province were analyzed. Among them, five provinces showed characteristics of open oceans, while four provinces reflected characteristics of coastal and high-latitude regions. Furthermore, a qualitative comparison was conducted with previous studies regarding marine ecological zones to provide a detailed analysis of the features of nine eco-provinces considering carbon cycling. Finally, we examined the changes in nine eco-provinces for four periods in the past (2001-2005, 2006-2010, 2011-2015, and 2016-2020). Rapid changes in coastal ecosystems were observed, and especially, significant decreases in the eco-provinces having higher productivity by large freshwater inflow were identified. Our findings can serve as valuable reference material for marine ecosystem classification and coastal management, with consideration of carbon cycling and ongoing climate changes. The findings can also be employed in the development of guidelines for the systematic management of vulnerable coastal regions to climate change.

MPLS망을 이용한 인터넷 멀티캐스트 라우팅 프로토콜 모델

김영준,Kim, Young-Jun 한국정보처리학회 2003 정보처리학회논문지 C : 정보통신,정보보안 Vol.10 No.1

본 논문은 MPLS(Multiprotocol Label Swtiching) 망에서 인터넷 멀티캐스트 라우팅 프로토콜을 지원하기 위한 방안을 제시한다. 인터넷 멀티캐스트 라우팅 프로토콜은 트리의 구성방식과 속성에 따라 최단거리트리 방식, 공유트리 방식 및 복합트리 방식 등으로 분류된다. 각 방식에 따라 MPLS 망에서 지원해야 하는 기능이 달라진다. 특히, 단/양방향성 트리 링크, Flooding/Prune 방식의 트리 구성, 하나의 멀티캐스트 그룹에 다중 트리의 존재 등 여러 가지 미해결이거나 해결하기 어려운 문제점들이 존재한다. 본 논문에서는 몇가지 가정을 세우고, 이를 바탕으로 각 멀티캐스트 라우팅 프로토콜을 MPLS 망에서 지원하기 위한 방안을 제시한다. Flooding/Prune 방식의 멀티캐스트 라우팅 프로토콜에 대해서는 새로이 브로드캐스팅용의 레이블을 정의하여 해결하고, 공유트리 방식에 대해서는 기 제안된 블록기반 멀티캐스트 전송기법을 도입하여 셀 인터리빙(Call Interleaving) 문제를 해결하며, 마지막으로 복합트리 방식에 대해서는 기존 멀티캐스트 라우팅 프로토콜에 수정된 SPT 전환 기능을 추가하므로써 MPLS 지원문제를 해결한다. 제안하는 방법이 기존의 방법보다 비교해 보았을 때 전송지연에서 우수한 성능을 보임을 모의 실험을 통해서 확인하였다. This paper describes the new method for Internet multicast routing protocols using MPLS (Multiprotocol Label Switching) networks. Internet multicast routing protocols are divided into three categories in terms if tree types and tree characteristics : a shortest path tree a shared tree and hybrid tree types. MPLS should support various multicast mechanisms because of extremely different IP multicast architectures, such as uni-/bi-directional link, Flooding/prune tree maintenance mechanism. the existence of different tree types with the same group, etc. There are so many problems over MPLS multicast that the solutions can't be easily figured out. In this Paper, we make a few assumptions on which the solutions of IP multicast routing protocols over MPLS networks are given. A broadcasting label is defined for the shortest path tree types. Cell interleaving problems of the shared tree types is solved by using block-based transmission mechanism. Finally, the existing hybrid-type multicast routing protocol is reasonably modified Shortest Path tree type to support MPLS multicast. It has been shown that these modifications give better performance (transmission delay) than the orignal method.

김영준,이종기,김명기,고홍섭,Kim, Young-Jun,Lee, Jon-Ki,Kim, Myeng-Ki,Kho, Hong-Seop The Korean Academy of Orofacial Pain and Oral Medi 2001 Journal of Oral Medicine and Pain Vol.26 No.3

본 연구는, 기존의 나열식 분류체계의 문제점을 극복할 수 있는 GRAIL을 이용하여 두경부의 해부학적 구조물들 및 구강 악안면 영역의 주요 질병들과 관련된 치의학 개념들의 모델을 구축한 뒤, 완성된 치의학 개념 모델이 두경부의 해부학적 구조물들 및 구강 악안면 영역의 주요 질병들을 잘 표현할 수 있는지와 기존의 GRAIL 모델이 지닌 특징에 잘 부합하는지를 평가하고자 시행되었다. 서울대학교 치과병원 내원 환자 중 포괄적인 치과 치료 병력을 지닌 환자 150명의 치과 의무기록을 내용별로 분석하고, 각종 치의학 교과서와 기존의 의학용어 분류체계에서도 모델 구축에 필요한 치의학 용어를 선택하였다. 이들 자료를 바탕으로, GRAIL 모델 구축을 진행하고 구축된 모델을 평가할 수 있는 소프트웨어 프로그램인 'KnoME'에서 치의학 개념 모델을 구축하고 평가하여, 다음과 같은 결론을 얻었다. 1. 환자 150명의 치과 의무기록을 내용별로 분석한 결과, 우선적으로 모델 구축이 필요한 치의학 용어로는, 해부학적 구조물의 경우 치아, 치은, 악관절, 입술, 턱, 혀 등의 순서로 나타났으며, 구강악안면 영역의 병소에서는 치아 우식증, 치주염, 치은염, 악관절 장애, 매복 지치, 치경부 마모 등의 순서로 나타났다. 2. GRAIL을 이용하여 치아, 치주조직, 구강점막조직, 치아 우식증, 치수 및 치근단 병소, 치주질환, 구강점막질환의 모델 구축을 시행한 결과, 치의학 개념간의 다양한 관계가 대다수 잘 표현되었다. 그러나, 구강 악안면 영역의 해부학적 구조물에 대한 공간 정의의 한계성과 구강 악안면 질환의 진행 양상에 있어서 표현의 어려움이 관찰되었다. 이러한 부분은 GRAIL을 치의학 분야에 적용할 때, 극복해야 할 한계로 나타났다. 3. 치의학 개념들에 관한 다양한 질의를 시행한 후 그 응답 내용을 평가한 결과, 완성된 모델 내에서 치의학 개념의 자동적인 분류가 이루어 졌으며, 다양한 목적의 검색이 가능하였다. 이와 같은 사실로 미루어 보아서, 완성된 모델은 기존의 GRAIL 모델의 특성에 잘 부합되는 것으로 생각되었다.

양극 벗김 전압전류법 (Anodic stripping voltammetry: ASV)을 이용한 인체 타액 내 납과 카드뮴의 검출: 예비 연구

김영준,김철,Kim, Young-Jun,Kim, Cheul 대한안면통증구강내과학회 2007 Journal of Oral Medicine and Pain Vol.32 No.4

The aim of this study was to evaluate the differences of salivary lead (Pb) and cadmium (Cd) concentrations, using ASV analysis, after various pre-treatment procedures. 10 unstimulated whole saliva samples of non-exposed subjects to Pb and Cd were collected. Each sample was divided into 6 aliquots and centrifugation was performed in only 3 aliquots. After centrifugation, 3 different types of pre-treatment procedures were carried out. Also, these pre-treatment procedures were carried out for another 3 aliquots, without centrifugation. Pre-treated aliquots were analyzed electrochemically, by ASV. The results are as follows: 1. Mean concentration of Pb in saliva after centrifugation was significantly higher than that of non-centrifugation. 2. In the detection sensitivity of Pb in saliva, those of simple dilution technique by HCl and acid digestion technique by nitric acid were significantly higher than that of simple dilution technique by electrolyte. 3. Mean concentration of Cd in saliva after centrifugation was significantly higher than that of non-centrifugation. 4. In the detection sensitivity of Cd in saliva, those of simple dilution technique by HCl and acid digestion technique by nitric acid were higher than that of simple dilution technique by electrolyte. But, there were no significant differences between them.
