로스앤젤레스 한인타운은 지난 10여 년에 걸쳐 소수민족 이민자들의 엔클레이브(enclave)에서 초국적 경제공간으로 변모하고 있다. 도시정부의 재개발 계획과 지역 한인들의 경제재활성화를 위한 노력이 진행됨과 동시에, 한국으로부터의 초국적 행위자들은 기업부문뿐만 아니라 부동산 시장에 공격적으로 투자하고 있다. 그러나 모순적이게도 이러한 다중스케일적 지리적 변동은 한인타운을 로스앤젤레스에서 가장 빈곤하고 위험한 내부도시의 하나로 전락시키는 데에 기여하고 있다. 본 논문은 장소에 기반한 아래로부터의 접근을 토대로 이러한 공간적 모순의 본질을 탐색하는데, 특히 헤게모니를 쥔 로컬 행위자들, 도시정부, 초국적 행위자들이 형성하는 다중스케일적 네트워크가 최근 한인타운이 지니는 일상적 삶과 유리된 재현의 경제를 발달시키고 있음을 지적한다. 또한, 본 연구는 이러한 한인타운의 도시재생이 이 구역에 거주하는 한인들과 라티노 노동자들을 포함하는 커뮤니티 구성원을 배제시키고 착취하고 있음을 밝히고자 한다. 결론적으로 본 연구는 한인타운의 지속가능한 미래는 민족 담론을 극복하고 인종, 민족을 횡단할수 있는 '장소기반의' 커뮤니티 의식에서 논의되어야 함을 주장한다.

Objective: The length of anterior-posterior commissure (AC-PC) in racial groups, age, gender of patients with deep brain stimulation (DBS) and pallidotomy were investigated. Methods: From January 1996 to December 2003, 211 patients were treated with DBS and pallidotomy. There were 160 (76%) Caucasians, 35 (17%) Hispanics, 12 (5%) Asians and 4 Blacks (2%). There were 88 males and 52 females in DBS-surgery group and 44 males, 27 females in pallidotomy group. Mean age was 58 year-old. There were 19 males and 19 females and mean age was 54.7 years in the control group. Measurements were made on MRI and @Target software. Results: The average AC-PC distance was 24.89 mm (range 32 to 19), which increased with aging until 75 years old in Caucasian and also increased with aging in Hispanic, but the AC-PC distance peaked at 45 years old in Hispanic. The order of AC-PC distance were $24.6{\pm}2$ mm in Caucasian, $24.6{\pm}2.24$ mm in Asian, 24.53 mm in Black, $23.6{\pm}1.98$ mm in Hispanic. The average AC-PC distance in all groups was 24.22 mm in female who was mean age of 56.35, 25.28 mm in male who was mean age of 60.19 and $24.5{\pm}2$ mm in control group that was excluded because of the difference of thickness of slice. According to multiple regression analysis, the AC-PC distance was significantly correlated with age, race, and gender. Conclusion: The AC-PC distance is significantly correlated with age, gender, and race. The atlas of functional stereotaxis would be depended on the Variation of indivisual brain that can influenced by aging, gender, and race.

Background: Different job strain formulations based on the Job Demand-Control model have been developed. This study evaluated longitudinal associations between job strain and psychological distress and whether associations were influenced by six formulations of job strain, including quadrant (original and simplified), subtraction, quotient, logarithm quotient, and quartile based on quotient, in randomly selected Japanese workers. Methods: Data were from waves I and II of the Survey of Midlife in Japan (MIDJA), with a 4-year followup period. The study sample consisted of 412 participants working at baseline and had complete data on variables of interest. Associations between job strain at baseline and psychological distress at follow-up were assessed via multivariable linear regression, and results were expressed as β coefficients and 95% confidence intervals including R² and Akaike information criterion (AIC) evaluation. Results: Crude models revealed that job strain formulations explained 6.93-10.30% of variance. The AIC ranged from 1475.87 to 1489.12. After accounting for sociodemographic and behavioral factors and psychological distress at baseline, fully-adjusted models indicated significant associations between all job strain formulations at baseline and psychological distress at follow-up: original quadrant (β: 1.16, 95% CI: 0.12, 2.21), simplified quadrant (β: 1.01, 95% CI: 0.18, 1.85), subtraction (β: 0.39, 95% CI: 0.09, 0.70), quotient (β: 0.37, 95% CI: 0.08, 0.67), logarithm quotient (β: 0.42, 95% CI: 0.12, 0.72), and quartile based on quotient (β: 1.22, 95% CI: 0.36, 2.08). Conclusion: Six job strain formulations showed robust predictive power regarding psychological distress over 4 years among Japanese workers.

There are two principal routes for the Asia-North America containerized cargo, that of Asia-West Coast and Asia-East Coast. On the West Coast, the Asia-Los Angeles, dominate the commerce, whereas on the Asia-East Coast it's the Panama Canal. Each of these routes has different characteristics. All are similar in that each is the door to the commerce of containerized cargo originating in Asia; each combines maritime and overland transportation; each has important intermodal connections and is able to distribute cargo throughout the West and East Coasts of the United States. Each route also has its port of preference that has the necessary infrastructure, equipment and intermodal connections. For example, in the case of the Port of Los Angeles, in spite of some of its advantages, it has several serious problems due to the interminable containerized cargo traffic that must be solved rapidly and satisfactorily in order to progress. In this paper, we would like to show the problems of two main routes.

L. A. 마모율 시험은 건설용 골재의 강도를 확인하기 위한 방법으로 주로 석산의 모암을 대상으로 시행하여 왔다. 본 연구는 경상분지 퇴적암이 집중 분포되어 있는 25 지점에서 지질학적 특성을 대표할 수 있는 324 브록의 시료를 채취하여 L. A. 마모율시험으로 각종 공학지수(일축 압축강도, 압열 인장강도, 탄성계수, 점하중 강도지수, Schmidt 해머 반발지수)를 추정하기 위한 실험을 시행하여 회귀 분석법으로 서로간의 상관성을 확인한 결과, 상호간 좋은 상관관계가 있음을 확인하였다. 이 방법이 다른 공학지수를 추정함에 손색이 없으므로 이후에도 많은 활용이 있기를 기대한다.
