          주얼리 디자인 자료구축을 위한 방법론 연구 2 -탄생화를 중심으로-

          남상원 사단법인 한국조형디자인협회 2009 조형디자인연구 Vol.12 No.1

          This study placed "methodologies for data construction of design in jewelry"at its purposive center: it was performed under the recognition that a field of jewelry design had not been pursued more effective and systematic method to design than various fields of industrial design. Through this thesis, I suggested a way to solve the problems related with effective design methods and to construct data for ideal jewelry design by examining the methods applied in various fields of industrial design. For accomplishing the purpose of this study, I used the birth flowers as a material for designing to construct data of design in jewelry. The processes and main results of this study were as follows : First, I have been studied a theory for the generalized methods to construct data of jewelry design. Those methods included two things: the principle of molding and the method of basic principle of the methodologies in design. Second, I choose the birth flowers as a material for design and used these as exemplar material for creating detailed data of jewelry design. The birth flowers were classified and arranged in day and month and finally flowers in month were analyzed for this study. These birth flowers were applied to plan a 'frame for showing(chart)' devised by each principle based on the basic principle of molding. 'The frame for showing' in this study was created based on the fundamental concepts of the methodology for design. It was also invented with considerations about the actual facets for designing jewelry goods. Third, I realized actual shape and feeling of the flower in december through the 3D rendering with the frame for showing. I tried to express the actual image of that flower by using 3D rendering and designed various other flowers by months. Through this work, I concluded that this frame for showing was essentially effective tool to solve the problems and create the products. The conclusions which can be drawn from this study of methodologies for data construction of design in jewelry are two facets: 1) the suggestion of direction for designing and 2) the possibility of pursuing the effective method to solve problem related with the design. Specifically, First, results in this study can suggest the direction with marketability for designers and manufacturers to invent and design the similar products. This make us so competitive to understand the consumer's inclination to design from past to present that we can make a solution to the problem very quickly and effectively. Second, by constructing a lot of data through this process, designers and manufacturers are able to make some essential elements for design. The application of this frame to the actual designing makes designers to approach the problems effectively. With regard to this effectiveness, a continual work for collecting and constructing data about designing can make possible to ceaseless development of designers and companies.

          Simple fabrication and characteristics of Zn2Ti3O8 one-dimensional nanostructures

          남상원,권용중,조홍연,강성용,나한길,김현우 한양대학교 세라믹연구소 2015 Journal of Ceramic Processing Research Vol.16 No.4

          For the first time, we report the fabrication of one-dimensional (1D) nanostructures of Zn2Ti3O8. We heated the TeO2/TiO2 core-shell nanowires in a Zn-containing environment. The variation in heating temperature drastically changed the morphology and structure of the composite nanowires, obtaining the 1D nanostructures of Zn2Ti3O8 at 700 ℃. A photoluminescence (PL) study indicated that annealing at 700 ℃ generated a PL band at 2.5 eV in the green region, originating from the Zn2Ti3O8 structure. These findings may pave the way to fabrication and applications of novel composite nanostructures.

          나노여과에 의한 중금속 함유 산성 폐에칭액의 재생(II) : 구리이온을 함유한 PCB 폐에칭액의 Dead-end 나노여과

          남상원,장경선,염경호,Nam,,Sang-Won,Jang,,Kyung-Sun,Youm,,Kyung-Ho 한국막학회 2013 멤브레인 Vol.23 No.1

          본 연구는 인쇄회로기판(PCB) 제조 시 에칭공정에서 발생되는 구리이온($Cu^{+2}$)을 고농도로 함유한 황산 폐에칭액을 NF 막분리법을 사용하여 에칭액 회수와 구리이온 처리를 효율적으로 수행하기 위한 NF 막여과 공정의 운전 조건을 설정하기 위한 기본 자료를 확보하는데 있다. 이를 위해 미국 Koch사의 SelRO MPS-34 4040 NF 막을 대상으로 구리이온을 고농도(5~25 g/L)로 함유한 모의 황산 폐에칭액의 회분식(dead-end) 나노여과 실험을 수행하여 투과 플럭스와 구리이온의 총괄 배제도를 측정하였다. 이 결과 황산용액에의 막 보관기간이 길수록, 황산용액의 pH가 낮을수록 황산에 의한 NF 막의 손상이 더 크게 발생하여 순수 투과 플러스가 증가하였다. 황산 폐에칭액의 투과 플럭스는 황산용액 내 구리이온의 농도가 증가할수록 막 표면에의 구리이온 농축(농도분극)의 증가에 따라 감소하였으며, 구리이온의 배제도는 구리이온의 농도가 높을수록, pH가 낮을수록, 황산용액 내의 막 보관기간이 길수록 낮아져 초기 37%에서 최소 15% 수준으로까지 감소하였다. In this study the nanofiltration (NF) membrane treatment of a sulfuric acid waste solutions containing copper ion ($Cu^{+2}$) discharging from the etching processes of the printed circuit board (PCB) manufacturing industry has been studied for the recycling of acid etching solution. SelRO MPS-34 4040 NF membrane from Koch company was tested to obtain the basic NF data for recycling of etching solution and separation efficiency (total rejection) of copper ion. NF experiments were carried out with a dead-end membrane filtration laboratory system. The pure water flux was increased with the increasing storage time in sulfuric acid solution and lowering pH of acid solution because of the enhancement of NF membrane damage by sulfuric acid. The permeate flux of acid solution was decreased with the increasing copper ion concentration. Total rejection of copper ion was decreased with the increasing storage time in sulfuric acid solution and copper ion concentration, and lowering the pH of acid solution. The total rejection of copper ion was decreased from initial 37% to 15% minimum value.

          외이도 이물에 의해 발생한 두개저 골수염 1예

          남상원,김덕림,김형종,홍성광 대한이비인후과학회 2012 대한이비인후과학회지 두경부외과학 Vol.55 No.11

          Otogenic skull base osteomyelitis (SBO) is a rare but life threatening disease, usually originating from a preceeding infection of the ear canal. It occurs dominantly in the elderly with diabetes or immunocompromised patients. However, foreign bodies in the ear canal may be a contributory factors causing otogenic SBO in healthy subjects. We describe a case of a previously healthy 51- year-old man, who was diagnoised with otogenic SBO after a physical exam and MRI scan. The patient complained of progressive otalgia lasting for one year and facial palsy that occurred three days before the visit. During the hospital course, an unexpected cotton swab was found in the ear canal. This was highly suspected as the main cause of otogenic SBO because, in the course of careful history taking, the patient remembered clearly that the cotton part of a cotton swab broke off in his ear a year ago. This case suggests that attention should be paid to high index suspicious foreign bodies in healthy subjects who are diagnosed with otogenic SBO, and extensive history taking and physical exam should be directed to this area.

          Black burnished pottery is the representative type of Hanseong Baekjepottery. It played an important role as a prestige object in the Three KingdomsPeriod. However, despite this importance, there has not been much researchundertaken on the production technology of black burnished pottery. In thisstudy, a large amount of black burnished pottery excavated from PungnabEarthen Wall Fortress was subject to both visual observation and scientificanalysis, and its production technology was studied. As a result, the use of ne clay, compact burnishing, and carbon adsorption(the most important element) could be confirmed for the black burnishedpottery. These technological properties were features of the indigenous Baekjeceramic tradition and through their combination, a new type of productiontechnology was reborn. In this study, an attempt was made to establish the standard technologicalsignature of black burnished pottery from the Baekje center. Then this wascompared with the technological signature of black burnished pottery excavatedfrom regional locations. As a result, it was possible to conrm regional variationsin production technology, according to which the black burnished pottery wasdivided into four categories. First, black burnished pottery that was producedaccording to the same technological method as that of the Baekje center. Second, black burnished pottery that was produced in the Baekje center andthen sent to powerful regional people. Third, indigenous examples that weremade to imitate the black burnished pottery of the Baekje center. Finally, blackburnished pottery that was produced with regional technologies which havenothing to do with the pottery of the Baekje center. It is thus possible to maintain that, in studying the black burnished potteryproduction techniques of each region and in exploring their meanings, the results can be used as a clue in understanding the past and the politicalrelationship between the Baekje centre and regional communities. 본고에서는 그간 백제사에서 중추적인 역할을 해왔음에도 불구하고 정작 흑색마연토기 본질 자체에 대한 연구가 미진했던 점에 착안하여 우선적으로 백제 중앙의 흑색마연토기란 무엇인지 자연과학 분석을병행하여 그 제작기법에 대해 연구해 보았다. 그 결과 흑색마연토기는 이미 백제 기층문화들의 토기 제작기술에 존재하였던 마연과 탄소흡착이라는 각 속성의 융합으로 재탄생된 ‘백제 중앙의 위세품'으로 볼수 있었다. 이러한 흑색마연토기는 초기 중앙에서도 상당한 위세품으로 취급되었으나 그간 축적된 풍납토성 및 몽촌토성과 같은 생활유구, 경기 일부지역 등의 출토 양상으로 미루어 볼 때 중앙의 경우 흑색마연토기 생산량이 점차 증가하며 보급이 확대된 것으로 확인되었다. 하지만 여전히 여타 토기들에 비해희소성을 보이며 특수기종에 집중된다는 점은 보급의 확대가 곧바로 대중화로 해석되기보다는 오히려대체 위세품의 등장, 귀족층의 두각, 기종의 고급화, 토기 생산시스템의 발달 등 물질문화의 자연스러운발전단계 속에서 여러 현상이 맞물려 나타난 결과로 판단된다. 반면 이러한 현상은 극히 중앙에 한정된현상이고 백제 중앙은 흑색마연기술의 독자성·특수성을 지향하며 이를 정치적 목적을 갖고 전략적으로활용하였다는 사실을 각 지방출토 고급 흑색마연토기의 제작기법을 통해 확인할 수 있었다. 실제로 지방 곳곳의 흑색마연토기들을 관찰해본 결과 지역에 따라 제작기법상의 차이가 존재했으며,이는 크게 네 가지 경우로 분류할 수 있었다. 첫째, 백제 중앙과 동일한 기술로 생산한 경우, 둘째, 중앙에서 생산된 토기가 지방에 사여된 경우, 셋째, 중앙 흑색마연토기를 모방 제작한 경우, 마지막으로 백제 물질문화와 상관없이 마한 토착기술로 제작한 경우이다. 이렇듯 각 지역 흑색마연토기들의 제작기술과 공반유물 비교연구는 당시 백제와 마한 재지세력 간의 정세관계를 파악하는 한 가지 단서로 활용될 수 있었다. 그 결과 제작기술의 비교연구는 그간 ‘흑색마연토기'=‘중앙의 사여품'=‘백제 영역화의표지유물'이라는 고정관념에서 탈피해야 한다는 사실을 시사하고 있다.
