Through the comparative studies on Korean and Chinese ethnobanks in the U.S., this research finds the difference in the social capital between Korean and Chinese American economy and reinterprets the social capital in overseas Chinese. In many ethnic studies, the ethnobanks in the U.S. are thought as the main drive of the economic prosperity in the ethnic communities. For the success of these ethnobanks, the relationship banking of these ethnobanks are contrasted with the arms-length banking of the mainstream U.S. banks. However there are the differences both in performance and business strategies even among different ethnobanks. Contrary to the Korean ethnic banks having much portion of business loans, Chinese ethnic banks have stressed real-estate loans in their loan portfolio. This research regards the differences of business strategies and performance of these ethnobanks as the result of the different social, cultural contexts in each ethnic community. From these finings, we can improve the understanding of the concept of social capital in overseas Chinese economy.

Incident detection rate and false alarm rate are the key measures tot estimating the performance of automatic incident detection algorithms. It is, however inherently very difficult to improve the two measures simultaneously. The main purpose of this study is to present some methods for solving the problem. For this, an incident detection algorithm has been designed in this study. The algorithm is consisted of two functions, one for detecting incident and another for detecting congestion. A logic for distinguishing non-recurrent congestion from recurrent congestion was employed in the algorithm. The new algorithm basically requires speed, flow, and occupancy data for defining incident situation, but the algorithm is able to perform this task without one of the three parameters. The performance of the algorithm has been evaluated by using the field data collected from Interstate Highway 880 in Bay Area, California. The empirical analysis results are very promising and thus, the algorithm proposed may be very useful for the analysts. This paper presents some empirical test results for the performance of California incident detection algorithm, only for the reference purpose.

The Early Miocene Temblor Formation forms an important sandstone reservoir at Kettleman North Dome oil field, California. Sandstones are mostly arkosic in composition except deepest sandstones containing much volcanic rock fragments. Arranged in paragenetic sequence prior to feldspar alteration, the Temblor sandstones contain cements of early calcite, dolomite, quartz, albite, mixed-layer ohloriteismectite (C/S) and smectite, and anhydrite. Diagenetic changes associated with feldspar are albitization of plagioclase, late calcite and laumontite cementation and grain replacement, plagioclase dissolution, and kaolinite cementation. Plagioclase albitization and late calcite and laumontite cementation in Temblor sandstones occurred at the time of maximum burial with temperatures up to $130^{\circ}C$. Volcanic plagioclases were selectively albitized. Most diagenetic changes are interpreted to have occurred before the maior uplift which occurred within the last one million years ago. Since then to the time of hydrocarbon emplacement plagioclase dissolution and kaolinite cementation occurred. This reaction occurred in relatively closed system due to the occurrence of kaolinite next to the site of plagioclase dissolution. Unaltered part of volcanic plagioclase and plutonic plagioclase which escaped albitization during maximum burial were preferentially dissolved to make plagioclase porosity. Secondary porosity resulting from dissolution of plagioclase and carbonate and anhydrite cements was mainly produced by formation waters containing organic acids released during atagenesis of organic matter.

One of the most lasting and influential projects for radical reform of Korean universities is a discourse on networking national and public universities. The discourse, proposed with a level equalization of universities as its ideological basis has raised various discussions and suggestions in the past 20 years. It was proposed as a fundamental solution to the 'disastrous' hierarchical structure of universities and 'hellish' entrance exam competition. This paper aims at reexamining the efficacy of its ideological proposition and its practicability at the present time in reference to such foreign cases, which have worked as model cases for this discourse: the reformation of the University of Paris and the California master plan for higher education in the 1960s. The two different contexts, however, should be considered in applying the cases to Korean university reform. 1) The foreign cases of united universities were formed 'naturally' in the expanding phases of higher education while the Korean project pursued 'artificially' in the midst of reconstructing process. 2) The foreign cases had an overall influence on education in general as most of the universities in those countries were public or national, while the effect of Korean project will be very limited as most of the university students attend private universities. Besides those differences, the new situations surrounding universities such as globalized competitiveness and technological innovation is making the idea of standardization of universities obsolete. Korean university reform should not be centered on the integration of universities but on their characterization and enhance the specific strengths of each group of universities.

In this study, we analyzed the intensity attenuation for M 6.0, 6.5, and 7.0 earthquakes using the broadband strong ground motion simulation platform based on the physical seismic modeling developed by the US Southern California Earthquake Center (SCEC). The location of the earthquake was assumed to be near the epicenter of the 2016 M 5.8 Gyeongju earthquake, but two of the representative US regional models provided by the SCEC strong ground motion simulation platform were used for the propagation model. One is the Central and Eastern United States (CEUS) model representing the intraplate region, and the other is the LA Basin model representing the interplate region. Five modeling methodologies are presented in the version 16.5 of the simulation platform, and Song and Exsim models were used in this study. In the analysis, we found that different intensity attenuation patterns can be observed with the same magnitude of earthquakes, especially depending on the region (CEUS vs LA Basin). Given the same magnitude and distance, the instrumental intensity in the CEUS region (intraplate) could be larger by a unit of 2 than that in the LA Basin region (interplate). Given the difference of intensity attenuation patterns observed in the study, it is important to know the regional intensity attenuation characteristics to understand the accurate level of seismic hazard imposed in the Korean Peninsula. This study also shows the level of the uncertainty of intensity attenuation if region specific attenuation characteristics are not considered.

The novel "The Grapes of Wrath" shows the painful reality of Americans during the Great Depression through the migration journey of the Tom Jod's family, who had no choice but to move from Oklahoma to California and their hardships in California. This presents empathy for their wrath and offers hope for a brotherly solution. This article presents institutional solutions against each novel situation from the perspective of the Constitution, labor law, and competition law. From a constitutional perspective, the poverty of Oklahoma's smallholders is not a result of choice, but is caused by the natural environment and capital concentration, so it is suggested that the government have to intervene to guarantee a minimum standard of living to realize equal rights. From a labor law perspective, worker supply projects are unconstitutional because they constitute intermediate exploitation of labor, and immigrants like the Joad family have the right to form labor unions. From a competition law perspective, it was shown that the large landowners' setting of fruit prices constitutes predatory pricing, and the farmers' attempts to pay similarly low wages constitute collusion. Through this, the attempt was made to recognize that the law is a means to resolve the public wrath that may currently exist, and to show that the story in the novel can bring empathy and understanding to minorities. It is hoped that reading novels can be a way to help interpret the law and sympathize with others as an indicator of a just society.

This study reviewed the groundwater policies of USA as a benchmarking for the purpose of improving groundwater polices, regulations, and plans in Korea. Each state of the USA has its own unique groundwater policies. Recently, severe drought in the western parts of the USA resulted in the launch of the California Statewide Groundwater Elevation Monitoring (CASGEM) program. CASGEM classified a total of 515 alluvial groundwater basins of the California State to four prior groups (high, medium, low, and very low prioritization). In Texas, a total of 101 Groundwater Conservation Districts (GCDs) over the state has controlled groundwater pumping amounts in their own management areas and 16 Groundwater Management Areas (GMAs) over the state have directly managed groundwater aquifer. Direct management for aquifers by GMAs would be the most scientific method for groundwater management, which expected to provide water consumers the more advavnced groundwater service. These groundwater management strategies of the USA can be possibly considered in groundwater plans for national and local governmental authorities, which possibly results in more optimal groundwater management in Korea.

현재 국내를 비롯하여 세계적으로 녹색성장, 친환경 등의 열풍이 고유가와 화석연료의 고갈위기와 맞물려 활발히 진행되고 있다. 이미 미국, 영국, 프랑스, 이태리, 일본 등의 선진국에서는 자연 친화적, 경제적 실리 추구 및 편리성을 추구하면서 청정 에너지를 사용하는 "미래형 이동수단"에 큰 관심을 갖고 우리보다 한발 앞서 나가고 있다. 2005년 2월 16일 발효된 기후변화의 주 요인인 온실가스 배출 감축을 위한 교토의 정서 또한 이러한 친환경이란 말과 무관하지 않다. 교토의정서의 발효 이후 세계 각국은 의무화된 규제조항을 만족하기 위해 막대한 자본을 투입하고 있다. 우리나라의 경우 온실가스 배출량이 세계 9위에 달하고 있으며, 전체 온실가스 배출량의 82.5% 정도가 화석에너지의 사용에 의해 발생되고 있다. 이중 이산화탄소의 경우 전체 배출량의 27%를 자동차에서 배출되며, 이로 인해 세계 각국에서는 자동차에서의 배출가스를 규제하는 조항을 법제화하고 있다. 이러한 규제는 앞서 미국의 경우 캘리포니아 주정부에서 1998년부터 전기자동차 사용을 의무화하는 ZEV 규제를 입법화하면서 본격화되었고, 무공해 및 저공해 자동차의 개발이 활발하게 진행되었다. 또한 고유가 시대로 접어들면서 대체에너지에 대한 필요성이 한층 고조되고 있는 실정이다. 이중 전기자전거는 배터리를 통해 무공해, 무소음이라는 장점을 가지고 있으며, 유지관리비가 거의 들지 않고 교통체증을 완화시켜주며, 주차에 신경쓰지 않아도 되어 교통수단에 혁신을 가져다 줄 것이라 생각된다. 또한 전기자전거의 경우 배터리를 동력원으로 사용하며 전동스쿠터 등에서의 문제점인 일충전 주행거리에 제약을 받지 않아 최근 중국 등에서 보급이 급격히 확산되고 있는 추세에 있다. 하지만 대부분 납축전지, 니켈-카드뮴 등의 배터리가 사용되고 있어 중량, 수명, 중금속에 의한 환경오염 등의 다양한 문제점을 내포하고 있다.
