        교통은 개인의 이동(mobility)에 기원을 둔다. 교통환경에서 이 같은 개인의 이동을 특정 값으로 제시하려는 이동성연구는 여러 각도에서 시행되어 왔으며, 그 결과로 통행자의 통행 서비스수준을 정량적으로 평가할 수 있는 다양한 방안이 제안되어왔다. 그러나 복합대중교통에 대한, 특히 지역적 범위에서 평가할 수 있는, 이동성연구는 많지 않았다. 본 연구는 복합대중교통망에 대한 이동성지표를 지점 대 지점에서 지역간 범위로 확대하여, 대중교통 승객의 접근시간, 주행시간, 환승시간을 고려한 대중교통 이동성지표를 제안한다. 복합대중교통의 이동성(mobility) 평가를 위하여, 대중교통 이동성을 도보수단까지 포함하였으며, 비교대안수단은 대중교통의 경쟁수단인 개인교통수단으로 설정하였다. 본 연구에서 제안한 대중교통 이동성 분석지표는 지역간 대중교통시설이 개인교통수단에 비해 어느 정도의 경쟁력을 가지는지(지표 1), 도보수단을 포함하여, 출발지역에서 도착지역까지 개인교통수단에 비해 얼마나 편리한지(지표 2), 이용자의 지역간 통행을 지원할 수 있도록 얼마나 많은 다양한 경로가 제공되는지(지표 3)를 평가할 수 있도록 설정하였다.

        The Emergence of Competitiveness in Korea-China Ship Distribution Industry

        노현수,김영근,이재승 한국유통과학회 2015 유통과학연구 Vol.13 No.7

        Purpose - This paper reviews the changes in the ship export and import structure between Korea and China. It utilizes the comparative advantage trade theory to analyze time-series statistical data from the market share index, revealed comparative advantage index (RCA), and trade specialization index(TSI). Research design, data, and methodology – Based on their economic phases, both Korea and China have similar country characteristics. The purpose of this research is to understand the two country’s trade structures to fortify the Korea-Sino economic relationship including verifying what is working and what is not. Results – Based on the analysis, bilateral economic activity to achieve a plus trade stimulus environment should be realized in the long run. Both countries should establish guarantee-free trade negotiations and boundaries instead of various non-tariff barriers. Conclusion – Reviewing the research, a sound competitive relationship can be grown for mutual benefit including export market diversification in the near future. The review of the Korea-Sino ship industry is keenly important and investigative research about it is timely because it is a major industry in each country.

        Tenuidraconema koreensis, a New Species of Marine Nematodes (Adenophorea: Desmodorida) from South Korea

        노현수,Won Kim 한국통합생물학회 2004 Animal cells and systems Vol.8 No.3

        Tenuidraconema koreensis, a new species of free-living marine nematodes, collected from the subtidal coarse sediments and various invertebrates of Namae, is described. The new species differs from T. fiersi Decraemer, 1989, the only other species in the genus, by having the combination of the following characters: the position of twelve cephalic adhesion tubes in both sexes (anterior six cephalic adhesion tubes inserted on the rostrum and posterior six inserted on the body annules), and the number of posterior sublateral adhesion tubes (12 in male and 13 in female) and posterior subventral adhesion tubes (15 in male and 19 in female). This paper contains the description of the new species with illustrations and scanning electron microscope (SEM) photomicrographs. This is the first discovery of the monotypic genus Tenuidraconema outside the type locality.

      • Crustacean Decapods of Jindo Island, Korea

        노현수,정종우,송성준,김원,Rho Hyun Soo,Jung Jongwoo,Song Sung Joon,Kim Won The Korean Society of Systematic Zoology 2005 Korean Journal of Systematic Zoology Special Issue Vol.5 No.-

        A taxonomic survey was carried out to see the decapod fauna of Jindo Island and its adjacent islet, Korea in June 2004. The 35 species in 13 families were identified in this study and of which 12 species of caridean shrimps in three families, one thalassinidean species, two anomuran species in one family, and two crab species in two families were newly added to the decapod faun3 of the study area. With the previously known 58 species in the Jindo Island and its adjacent islets, a total of 75 species are listed with some brief remarks. Distribution patterns of species are also discussed based on the composition of geographical distribution forms. 진도의 십각류 종류상을 밝히기 위해 분류학적 연구를 수행하였다 그 결과 13과 35종이 동정되었으며, 이 가운데 새우류 3과 12종, 쏙류 1종, 집게류 1과 2종, 게류 2과 2종이 진도의 십각류 종류상에 새로이 추가되었다. 과거기록을 포함하여 총 75종의 분류목록을 작성하였으며, 주요 분류군들에 대해서는 간략한 고찰을 하였다. 또한 이미 분포상이 밝혀진 십각류 73종의 분포형과 종 출현 양상을 근거로 진도와 그 인근도서의 십각류 분포 양상을 논하였다.

        Trade Structural Analysis of the Steel Distribution Industry between Japan and USA

        노현수,김영근,이재승 한국유통과학회 2014 유통과학연구 Vol.12 No.11

        Purpose – This study evaluates the mutual influential power regarding the trade volumes of Japan and USA, based on a literature review and an empirical analysis. Through the literature review, I could evaluate each country’s actual import-export volume and its status. Further, I could evaluate how each country could influence its trade outcome, through empirical analysis. Research design, data, and methodology – This study aims to review the trade structure to improve Japan-USA economic and social cooperation, as the two countries have reciprocal complementary features, and to examine trade weaknesses and analyze factors influencing trade and its direction, as well as to identify ways to expand trade. Results – The intra-economic potential cooperation fields are numerous. Additionally, anticipated profits from these fields are stable as compared to other fields in the regional economic integration. Conclusion – The interrelations between the two economic identities can provide optimal opportunities for industrial technology cooperation. Under the current aggravated competition in industrial fields, it is advisable to identify ways to secure stable resource suppliers, including the development of export markets.

        A new free-living marine nematode species of the genus Dracogalerus Allen and Noffsinger (Nematoda: Draconematidae) from a shallow subtidal zone of Jeju Island, Korea

        노현수,Won Kim 한국통합생물학회 2005 Animal cells and systems Vol.9 No.3

        A new species of free-living marine draconematid nematode, Dracogalerus koreanus n. sp., is described from the shallow subtidal coarse sediments and various invertebrates of Jeju Island, Korea. This is the first record of this genus from Korea. Dracogalerus koreanus n. sp. is morphologically most similar to D. cryptocephalus (Irwin-Smith) in having similar head shape (rostrum broadly rounded anteriorly) and eight cephalic adhesion tubes, but differs by the small number of rounded protuberances on the ventral side of non-annulated tail end (5 vs 6), small number of posterior subventral adhesion tubes in male (5-6 vs 8), intermingled somatic setae (5-6 vs absent), spicules (slightly curved and relatively thick vs strongly curved and very slender), and higher c value in male (8.8 vs 7.5).

        The Effect of Yangkyuk-Sanhwa-Tang on Cytokine Production in the Patients with Cerebral Infarction

        노현수,이상민,배영춘,박혜선,이재흥,송승연,유관석,주종천,Lo, Hyun-Soo,Lee, Sang-Min,Bae, Young-Chun,Park, Hye-Sun,Lee, Jae-Heung,Song, Seung-Yun,Yoo, Kwan-Seok,Joo, Jong-Chon The Society Of Sasang Constitutional Medicine 2004 사상체질의학회지 Vol.16 No.1

        Yangkyuk-Sanhwa-Tang(YST) has been widely used as a formula for the Soyangin cerebral infarction (CI) patients according to Sasang constitutional philosophy. Brain cells produce cytokines and chemokines during the inflammatory process after stroke both in animal models and in patients. Previously, regulation of serum cytokine levels by YSThas been observed in individuals at the acute stage of CI disease, but there have not been other scientific investigations on YST. The author investigated the effect of YST on theproduction of various cytokines using peripheral blood mononuclear cells (PBMCs)from the Soyangin (CI) patients, and Soyangin normal group. The cytokine production was analyzed using enzyme-linked immunosorbent assay (ELISA). The amount of interleukin (IL)-1, IL-1, IL-6, IL-8, and tumor necrosis factor (TNF)- in culture supernatant significantly increased in the LPS-treated cells compared with unstimulated-cells (P < 0.05). However, in LPS-stimulated PBMCs, cytokines level in CI patients group was higher than that of normal group. YST (1 mg/ml) significantly inhibited IL-1, IL-1, and IL-8 production in PBMCs stimulated with LPS (about 85% for IL-1, 87% for IL-1, and 53% for IL-8, P < 0.05), but did not significantly inhibit IL-6 and TNF- production in the CI patients group. We also show that YST significantly increased LPS-induced IL-1, IL-6, and TNF- production in the normal group. Thesedata suggest that YST has a regulatoryeffect on the cytokine production, which might explain its beneficial effect in the treatment of CI.
