There are three main rice-growing regions in the United States: the prairie region along the Mississippi River Valley in eastern Arkansas; the Gulf Coast prairie region in southwestern Louisiana and southeastern Texas; and the Central Valley of California. The Central Valley of California is producing about 23% of the US rice(Fig. 1). In California. most of the crop has been produced in the Colusa, Sutter, Butte, Glenn Counties of the Sacramento Valley since 1912, when rice was commercially grown for the first time in the state(Fig. 2). Roughly speaking, the average annual area sown to rice in California is about 300,000 acres to 400,000 acres during the last forty years(Fig. 3). California rice is grown under a Mediterranean climate characterized by warm, dry, clear days, and a long growing season favorable to high photosynthetic rates and high rice yields. The average rice yield per acre is probably higher in California than in any other rice-growing regions of the world(Fig. 4). A dependable supply of irrigation water must be available for a successful rice culture. Most of the irrigation water for California rice comes from the winter rain and snow-fed reservoir of the Sierra Nevada mountain ranges. Less than 10 percent of rice irrigation water is pumped from wells in areas where surface water is not sufficient. It is also essential to have good surface drainage if maximum yields are to be produced. Rice production in California is highly mechanized, requiring only about four hours of labor per acre. Mechanization of rice culture in California includes laser-leveler technology, large tractors, self-propelled combines for harvesting, and aircraft for seeding, pest control, and some fertilization. The principal varieties grown in California are medium-grain japonica types with origins from the cooler rice climates of the northern latitudes (Table 1). Long-grain varieties grown in the American South are not well adapted to California's cooler environment. Nearly all the rice grown recently in California are improved into semidwarf varieties. Choice of variety depends on environment, planting date, quality desired, marketing, and harvesting scheduling. The Rice Experiment Station at Biggs is owned, financed, and administered by the rice industry. The station was established in 1912, as a direct result of the foresight and effort of Charles Edward Chambliss of the United States Department of Agriculture. Now, The station's major effort is the development of improved rice varieties for California.

Spanish missionaries started to grow vine grapes and make wines in California 230 years ago. Earlier pioneers of the land started to do the same works for commercial purposes 130 years ago. Now California became one of the most important wine making places of the world. The quality of California wines in fact have been acknowledged as the best in the world by being ranked on the top in international wine tasting competition, such as Paris Tasting. A large wine cluster, consisted of grape growing, wine making, wine tours, and research and education, has been created in the area centered by Napa and Sonoma, California. In this context, this paper examines the process of formulating the cluster, factors contributing the success, articulates core actors, and draws policy and theoretical implications. It concludes that innovative actors, such as winery founders, local universities, and business organizations, have played key roles in establishing the California wine cluster.

This paper explores how effectively the newly introduced planning process - California Senate Bill No. 375 will achieve the regional GHG emissions target under the California policy and planning framework and how well incentive based environmental policy might perform. The new legislation creates a future growth scenario to reduce greenhouse gas (GHG) emissions with incentives as means of implementation of AB 32 - the Global Warming Solution Act of 2006 and includes five important policy and planning aspects: 1) the role of sustainable communities strategies (SCS) as one of the key elements in their regional transportation plans; 2) planning for transportation and housing; 3) specified incentives for the implementation of SCS; 4) the regional planning approach toward reducing GHG emissions; and the role of the California Air Resources Board to establish the regional GHG emissions target. This has significant implications for regional and environmental planning with incentives - resources allocation and approval process.

This study was carried out to investigate the differences of aroma and taste components among three kinds of kiwifruits from Korea, New Zealand and California. The moisture contents, pH, titratable acidity, organic acid, free sugar and volatile aromas were compared. The free sugar and organic acid were measured simultaneously by GC. Volatile aromas were extracted by simultaneous distillation and extraction and analyzed by GC and GC/MS. The moisture contents, pH and titratable acidity showed almost no differences among the three samples. Among the organic acids, malic acid contents were different. Citric acid contents were similar level. Quinic acid in Korean kiwifruits was extremely low compared to other samples. The total sugar contents were similar in three kiwifruit groups. The composition of major flavor components such as ethyl butanoate, hexanal, propyl butanoate, ethyl pentanoate, 2-hexenal, hexanol, hexanal, linalool oxide, methyl benzoate were different among Korean, New Zealand and California Kiwifruits.

전력시장에서의 적정 설비예비력을 확보하는 문제는 구조개편의 진행과 캘리포니아 전력비상사태 이후 더욱 더 중요성을 가짐에 따라 이에 대한 심도 있는 논의와 분석이 필요하게 되었다. 이런 이유로 현재 해외전력시장에서 활용중인 적정 설비예비력 확보방안들을 이론적 및 실증적인 방법에 의한 비교 분석을 통하여 한국전력시장에 적합한 방안을 모색하고자 한다. 본 논문에서는 특히 미국 PJM 전력시장 등에서 활용중인 용량의무 방식과 캘리포니아 시장에서 활용중인 시장의존방식을 중심으로 적정 설비예비력 확보방안을 간략하게 비교하고자 한다.

범죄예방이 무엇보다 중요한 형사정책의 한 축으로 자리매김 하면서 경찰활동도 다양한 변화를 추구하고 있다. 근세 이후 범죄통제경향의 변화에서도 알 수 있듯, 종국적으로는 범죄예방이 범죄통제의 최선이라는 경험을 바탕으로 경찰의 역할에 대한 새로운 시각의 등장과 더불어 나타난 것이 오늘날의 지역사회경찰활동이다. 이와 같은 경찰의 지역사회활동과 관련하여 본 연구는 미국 캘리포니아 북부에 위치한 산마테오카운티 보안관실의 C.A.R.O.N프로그램에 대하여 살펴보고자 한다.
