The fact that the Korean plosive consonant forms a three-way opposition between plain plosive, aspirated plosive, and laryngealized plosive has been frequently mentioned as one of the typological characteristics of Korean. However, this is not the result of empirical studies based on large-scale language data, but one of the surface comparisons with several well-known languages. So there is room for reconsideration in the objectivity and reliability of previous argument. In this paper, I compared and analyzed the plosive inventories of 4,356 languages, a very large-scale language data, and then examined the typological aspects of Korean plosive system. In aspects of quantity such as the number(9) and ratio(47.4%) of plosives, three places of articulation, and three-way opposition, the plosive system in Korean did not deviate significantly from the average of all languages. On the other hand, the qualitative profile is completely different. It is not easy to find a same plosive system with Korean which there is no opposition by [±voiced], one of the most universal in world´s languages, and consist of three voiceless plosives(plain, aspirated, and laryngealized one) that is in contrastive proportionally in three places of articulation. Through this, it can be concluded that the plosive system of Korean is quantitatively universal, but qualitatively specific. 이진호, 2020, 한국어 파열음 체계의 언어 유형론적 고찰, 어문연구, 186 : 5~29 한국어의 파열음 체계가 평음, 유기음, 경음의 삼항 대립을 이룬다는 사실은 한국어의 유형론적 특징의 하나로 이전부터 널리 언급되어 왔다. 그러나 이것은 대규모 언어 자료에 기반한 실증적 연구의 결과가 아니고 잘 알려진 몇몇 언어와의 표면적 비교 결과이기 때문에 재검토의 여지가 존재한다. 이 글에서는 4,356개라는 대규모 언어의 파열음 체계를 비교 분석한 후 이에 근거하여 한국어 파열음이 어떠한 양상을 보이는지를 구체적으로 살펴보았다. 그 결과 파열음의 수나 비율, 조음 위치의 수, 대립항의 수 등과 같은 양적인 측면에서는 한국어의 파열음 체계가 전체 언어의 평균치에서 크게 벗어나지 않았다. 반면 삼항 대립의 음운론적 성격, 유무성 대립의 부재, 비례 대립의 성립 등과 같은 질적 측면에서는 동일한 유형을 찾기 어려울 만큼 독특한 모습이었다. 이를 통해 한국어 파열음 체계는 양적으로는 보편성을 보이지만 질적으로는 상당한 특수성을 보인다고 결론 지을 수 있다.

환원된 Ni/Y - Zeolite 촉매에서 니켈 금속의 분포가 일산화탄소 수소화 반응에 미치는 영향

이진호,임선기,이동근,최선엽 한국화학공학회 1989 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.27 No.4

Ni/Y-Zeolite 촉매를 수소분위기하에서 여러 조건에서 환원시켜 니켈 금속 입자의 분포를 조절하고, 이에 따른 일산화탄소 수소화 반응의 활성 및 선택성 변화를 관찰하였다. TPR/TPO, TEM, XRD 및 FMR 관찰에 의하면 환원된 Ni/Y-Zeolite 촉매에서 니켈 금속은 이중 분산 분포를 나타내었다. 즉, Zeolite의 세공 내에는 고도로 분산된 니켈 cluster가 존재하였고, 반면에 Zeolite의 외부표면에는 주로 큰 니켈 입자가 존재하였다. 일산화탄소 수소화 반응은 1기압, 270℃ H₂/CO의 비가 3인 상태에서 작동하는 미분형 반응기에서 수행되어 졌다. 니켈 금속 입자의 분포는 반응활성 및 탄화수소 생성물의 분포에 크게 영향을 주었다. 고도로 분산된 니켈 cluster의 분율이 증가할수록 반응활성은 감소하였으나, 분자량이 큰 불포화 탄화수소의 생성이 두드러지게 증가하였다. 특히 모든 니켈 금속이 고도로 분산된 상태로 Zeolite 세공 내에 존재하게 될 때, C₁과 C₄ 탄화수소가 주로 생성되는 현상이 관찰되었고, 이는 촉매 내에 존재할 것으로 예상되는 Ni^+이온에서 1차로 생성된 에틸렌이 중합반응에 의해 부텐으로 전환되기 때문인 것으로 생각된다. The influence of nickel metal distribution on the properties of Ni/Y-zeolite catalysts for CO hydrogenation was investigated. The studies using TPR/TPO, TEM, X-ray line broadening and FMR have shown the existence of a bidispersion of nickel metal particles; i.e., small particles were restricted inside the zeolite pores, and large particles were formed outside the zeolite crystal. CO hydrogenation reaction was performed in a differential reactor operating at atmospheric pressure, 270℃ and H₂/CO ratio of 3. Nickel metal distribution affected the activity and hydrocarbon product distribution significantly. With increasing fraction of nickel metal inside the zeolite pores the activity continued to decrease, while the production of the long chain and olefinic hydrocarbons was enhanced significantly. Especially when all the nickel metals were restricted within the pores of zeolite, a bimodal hydrocarbon product distributions for C₁ and C₄ were observed. This was ascribed to the dimerization of the primarily formed ethene to butene on the active species of Ni^+ cations.

Locoregional recurrence is the most common type of recurrence in surgical operation of gastric adenocarcinoma, and peritoneal dissemination is one of the most difficult problems in advanced gastric adenocarcinoma treatment. Because the peritoneal cavity is the most common site of the first recurrence after gastric cancer resection, intraperitoneal chemotherapy seems a logical choice for cancer chemotherapy. In this study, Mitomycin C (MMC)-activated charcoal (CH)-alginate (ALG) beads were prepared by the mixtures of CH particles adsorbed with MMC as an anti-cancer drug and aqueous alginate solution. The alginate is recognized as biodegradable, nontoxic, and biocompatible. The release of MMC from the beads in 0.1 M Tris buffer was stable and continuous until about 1 week. The MMC-CH-ALG beads can be applied in the peritoneal cavity for intraperitoneal chemotherapy since they provide a good adhesiveness on the tissue and controlled release pattern of the drugs.

효울적인 멀티미디어 데이터 전송을 위한 ATM 통신망의 성능 분석

李振鎬 慶一大學校 1999 論文集 Vol.16 No.3

In this paper, the ATM network had been constructed by using the SBA 200(E) ATM Sbus adaptor(workstation), the ForeRunner LE 155 Mbps adaptor(PC) and the ASX-200 ATM switch supplied Foresystem. As it was solved the practical bandwidth for each established bandwidth, it could be assigned adequate bandwidth for each media in multimedia data transmission. If the bandwidth required in QoS negotiation is 11~63 Mbps, it is recognized that it may negotiate as the established bandwidth of 20~120 Mbps. As a result, in transmitting the multimedia data including image data and voice data, it is required the strategy for the assignment of bandwidth and QoS negotiation in order that the total bandwidth on various services may be within the scope of 63 Mbps. And it is desirable that the buffer size sets up as 5 Kbytes.

전도기판에 탑재된 단일모듈과 공기류와의 각도에 따른 냉각특성 연구

이진호,예용택,조승환 경일대학교 2001 論文集 Vol.17 No.-

The effect of thermal resistances and materials of board on cooling of a module was experimentally investigated. The problem considered is relevant to the cooling of electronic equipment made up of components mounted on a flat board. It is an aim of this experiment is to estimate temperature of module on the board that is the role of an expanded conducting surface. The study is performed with a variation of parameters that are the thermal resistance(Rc =158K/W, 0.05K/W), material of board, inlet velocity(V = 0.2∼ 1.5m/s), attack angle(θ=0˚∼45˚), and input power(Q=3W, 7W). The results show that input power was most effective parameter on the temperature difference between module and inlet air and as the attack angle increases, the temperature difference between module and inlet air increases.

PC관련 웹 문서의 한-영 교차 단어 비교법

The Web grows rapidly and access to international information through the Web occurs quite often. Many people access not only pages written in their own lanaguage but also ones written in other languages. Therefore, CLIR(Cross Language Information Retrieval) or TLIR(TransLingual Information Retrieval) becomes an important research issue. We study Korean-English cross words and try to develop an efficient method matching Korean-English cross words. Since we start this research with PC related information, there are many words of foreign origin. We consider two cases for matching. First, translated Korean words in dictionary corresponding to English words are used. Second, words of foreign origin are considered more seriously and two approaches for the words have been studied again. First, segmenting Korean consonants and vowels after preprocessing using several rules is done, and a table of possible Korean phonemes for English alphabets is made. The possible matching Korean words for an English word are given in order along with matching scores. Second, English pronunciation symbols and Korean components (consonants and vowels) are compared, and the result answer type is boolean. We select a Korean PC portal site and almost ten English PC portal sites, and test the proposed method to identify related Web pages in two sites. The result seems promising and further study is needed.

비장티푸스 살모넬라증에 의한 장열과 장천공은 매우 드물다 저자들은 방어기전의 손상이 없는 건강한 성인에서 비장티푸스성 D군 살모넬라 장열에 동반된 장천공이 발생한 예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. The case of enteric fever and bowel perforation caused by nontyphoidal Salmonella spp. is extremely rare. We report a case of a 28-year-old man who suffered from enteric fever with complicated a small bowel perforation, which is a known complication of S. typhi and S. paratyphi infections. The culprit later proved to be nontyphoidal group D Salmonella spp. in our case.
