This study discusses some features observed in Korean credit card industry, which is classified as a two-sided market. First, I summarize six characteristics or conditions that two-sided markets possess by reviewing related literatures, and consider if we can find out those peculiarities in Korean card industry. Second, this study casts light upon the unique issues which have not been handled in previous studies, that is another two-sidedness in mature two-sided markets. In the context of credit card industry, this additional two-sidedness is created by specific consumers group existing in entire consumer group in a card firm as a form of subset and specific partnering merchants group offering special benefits to their subset consumer group, or alliance card holders. This concept gives new idea that there could be multiple two-sidedness especially in mature two-sided markets, which will be significant to platforms' pricing strategies and expand the scope of related studies.

When an underground pipeline runs parallel with DC electric railways, it suffers from electrolytic corrosion caused by the stray current leaked from the railway negative returns, i.e., the rails. Perforation due to the electrolytic corrosion may bring about large-scale accidents even under cathodically protected condition. Traditionally, drainage bonding methods have been widely used as a mitigation method for stray current interference. In particular, the increased adoption of forced drainage method to gas pipelines makes the interference much more sophisticated. In this paper, we analyze the electric interference between pipelines and railways from the results of field investigation carried out in Seoul and Busan.

지열에너지는 지구가 생성될 당시부터 지구 내부에 존재하는 무한한 열에너지로 온실가스 배출이 적으며 태양광이나 풍력 등 다른 신재생 에너지와는 달리 일정한 에너지를 공급할 수 있는 항상성 에너지로 기저부하를 담당할 수 있다. 지열을 이용한 전력 생산은 1904년에 이탈리아 라데렐로에서 처음으로 시작되었으며, 현재까지 화산지대를 중심으로 활발히 이루어지고 있다. 2001년에서 2005년 사이에 전세계 지열발전용량은 약 13% 증가하였으며, 2005년을 기준으로 약 8,933MWe의 지열발전설비가 가동 중이다. 최근 들어 지하 심부까지 시추하여 지열저장소(geothermal reservoir)를 형성하고 이를 통해 지열에너지를 생산하는 새로운 시스템인 EGS(Enhanced Geothermal Systems)가 개발됨에 따라 비화산지대에서도 지열발전소를 건설하려는 움직임이 가속화되고 있다. EGS는 지하 심부의 불투수성 결정질 암반에 존재하는 지열에너지의 경제적인 생산뿐만 아니라 물을 주입하여 생산시키는 순환 방식을 이용하여 지열에너지 획득의 매개 역할을 하는 지열수의 고갈 문제를 해결하였다. 결정질 암반에서의 지열저장소의 형성은 암반 내에 분포하는 불연속면에서 주로 발생하며, 이를 위한 압력 조건은 현지 암반의 응력 분포 특성과 암반 및 불연속면의 물성에 좌우된다. 시추공을 통해 지하 심부의 암반에 수압이 가해지면 물의 주입으로 불연속면의 마찰력이 감소하며, 이로 인해 불연속면에 전단변형이 발생하게 된다. 전단변형은 불연속면을 열린 상태로 유지시켜 지열저장소를 형성하게 된다. 불연속면의 전단 변형시 발생하는 미소 탄성파는 시추공 주변에 설치한 모니터링 장비에서 측정되며, 모니터링 장비에 의해 측정된 미소 탄성파 발생 지점의 클러스터는 지열저장소의 공간적 분포 및 규모를 추정할 수 있는 자료가 된다. 현재 EGS를 이용한 지열발전 프로젝트는 프랑스 슐츠, 스위스 바젤, 호주 하바네로에서 대표적으로 진행 중이다. 슐츠는 현재 1.5MWe의 파일럿 플랜트를 가동 중이며, 하바네로는 파일럿 플랜트 건설 단계를 진행중이다. 스위스 바젤은 지열저장소를 형성시킬 목적으로 수행된 주입시험에서 발생된 문제에 대한 기술의 신뢰성을 확보할 목적으로 잠시 중단된 상태다. 제주도는 신생대에 분출하여 형성된 대표적인 한국의 화산지형으로 지열부존 가능성이 높을 것으로 예상되는 지역이다. 따라서 폐사는 지열에너지 부존 특성을 파악하기 위한 심부 물리 탐사 및 탐사정 시추가 실시될 예정이며 궁극적으로 국내 최초의 상용화된 지열발전소 건설을 목표로 하고 있다.

Current observations were carried out in Jinhae Bay area during the period of January to February 1974. The data were synthetically analyzed and the characteristics of the water movement in Jinhae Bay were studied. The water movement in Jinhae Bay area is a reversing tidal current type and the Semi- diurnal tidal current is predominant. The ebb current begins at about high water time and the strongest current occurs at about 3 hour after high water. The flood current begins at 0.2-1.0 hour before low water and the strongest current occurs at about 3-4 hour after low water. The main ebb current flows to SE direction with the maximum welocity, about 100cm/sec and the lood flows to NW with the maximum velocity, about 70cm/sec. Generally, the ebb current in Jinhae Bay is more predominat than the flood current except at the west and the north coast area of Gadeog-do where the flood current is more predominant.

기술 패러다임의 변화는 전체 산업구조를 변화시킬 뿐 아니라 새로운 산업 분야를 만들어내고 현존하는 산업분야 내의 기술을 변화시킨다. 기술혁신의 산업별 유형에 관한 Paviit의 연구는 이러한 산업분야 별 기술적 특성의 다양성, 즉 기술 패러다임 변화에 토대를 두고 있으며 그의 산업분류는 많은 후행 연구에서 인용되어 왔다. 그럼에도 불구하고 Paviit의 연구는 분석이 특정 시기에 국한되고, 정량적 분석이나 시간의 흐름을 고려한 동적 분석이 부족하며 일부 산업분야의 데이터가 미흡하다는 점 등, 데이터 분석과 관련된 몇 가지 한계점을 가지고 있다. 따라서 본 논문에서는 Paviit 연구의 한계점을 극복하고자 1975년과 1999년 사이에 미국특허청(USPTO)에 등록된 특허에 대한 자료 및 특허인용에 대한 자료를 이용하여 실험적인 분석을 실시하였다. 산업구조의 변화를 고려하여 Pavitt이 제시한 4개의 산업 유형은 1)공급자 지배형(Supplier dominated), 2)규모 집약형(Scale intensive), 3)전문 공급자형 (Specialized suppliers), 4)화학 기반형(Chemical science based), 5)생명과학 기반형(Bio-science based), 6)정보과학 기반형 (Information science based)의 6개로 확장되었다. 이와 같이 도출된 각 산업 유형 별로 A)특허 네트워크(Patent Network), B)기술 궤적 (Technology Trajectory) 두 가지 측면에서 분석을 실시하였다. 우선 특허 네트워크 분석은 기술발달 과정에서의 지식 흐름을 연구하기 위한 분석으로, 산업 내 분석으로는 각 산업에 속한 특허들의 관계의 측면에서 긴밀성을 나타내는 네트워크 밀도와 기술 지식의 집중 정도를 나타내는 네트워크 중심도를 산출하였고 산업간 분석으로는 산업간 지식 흐름의 양상을 살펴보았다. 또한, 기술 궤적 분석에서는 각 산업별 기술의 특성을 분석하는 것으로, 특정 기술 지식의 활용 기간을 통해 기술 주기를 도출하고, 산업 내 평균 권리 청구 항목 수를 이용하여 각 산업의 기술 범위를 비교하였다. 각각의 동적 분석을 통해 시간에 따른 변화 양상이 관찰하였고, ANOVA 분석을 이용하여 통계적 유의성을 검증하였다. 본 연구는 현재의 기술 패러다임 내에서 Pavitt이 제시한 산업 분류의 근거를 보충 설명하였고 특허 정보를 이용하여 기술혁신의 산업별 유형에 대한 폭넓은 분석방법을 제시하였다.

The effect of wave and current interactions on jet-like current flowing against waves was investigated based on numerical simulations. The numerical simulations were conducted using a model system of REF/DIF(a wave model) and SHORECIRC(a current model). In the simulations, irregular waves refracted due to the jet-like opposing current were focused along the centerline of current, and the jet-like current was spreaded earlier when the wave heights become larger. The numerical results show that the rapid change of wave height distribution in transverse direction near current inlet plays a significant role to spread the jet-like current. In other words, the radiation stress gradients acting in transverse direction have a more significant effect on the jet-like current than its gradients acting in flowing direction which tend to accelerate the current do. In conclusion, it is indispensible to take into account the interaction between waves and current when the jet-like current such as river mouth meets opposing waves.

The purposes of this study were 1) to find out any significant relationships among genderlogy, gender identity of clothing, and attitudes toward unisex clothing, 2) to investi- gate differences in genderlogy, gender identity of clothing, and attitudes toward unisex clothing between female and male college students, 3) to understand the structual dimension of genderlogy. The theory of this study was Bem's androgyny sex role theory which suggested an individual's masculine and feminine sex role lied on separate lines rather than on a linear line. The research design was an ex post facto survey and the subjects were 222 female college students and 179 male students in Taejeon, Chungnam and Chungbuk province. Using the SPSS program, factor analysis, 1-test, Pearson correlation coefficient, and plot were calculated for statistical analysis. The findings of this study were summarized as follows: 1) The 1.test showed significant differences in genderloy, gender identity of clothing, attitudes toward unisex clothing between female and male college students. 2) There were significant relationship among genderlogy, gender identity of clothing, attitudes toward unisex clothing. 3) The moi or dimensions of genderlogy were found to be traditional sex role and equal sex roles. There were only moderate negative relationship between traditional and equal sex roles and these two dimensions affected differently on the gender identity of clothing, as well as the attitudes toward unisex clothing, therefore traditional sex roles and equal sex roles seemed to lie on separate lines, and the androgyny sex role theory was supported.
