ObjectiveaaAlthough somatic symptoms are common complaints of patients with major depressive disorder (MDD), their associations with suicide are still unclear. MethodsaaA total of 811 MDD outpatients of aged between 18 to 64 years were enrolled nationwide in Korea with the suicidality module of the Mini-International Neuropsychiatric Interview (MINI) and the Depression and Somatic Symptom Scale (DSSS). ResultsaaOn stepwise regression analysis, current suicidality scores were most strongly associated with chest pain in men, and neck or shoulder pain in women. Severe chest pain was associated with higher current suicidality scores in men than in women, whereas severe neck or shoulder pain showed no significant differences between the genders. In conclusion, MDD patients of both sexes with suicidal ideation showed significantly more frequent and severe somatic symptoms than those without. Current suicidal risk was associated with chest pain in men, and neck or shoulder pain in women. ConclusionaaWe suggest that clinicians pay attention to patients’ somatic symptoms in real world practice.

The rate of dependence among ever-users of a drug indicates the risk of developing dependence once an individual has been exposed to the drug. This is the first study to investigate 12-month tobacco dependence (TD) among ever-smokers in a community-based population. Analyses were based on two national studies of representative samples aged 18-64 in 1984 (n=5,025) and in 2001 (n=6,275), conducted with household visits and face-to-face interviews. The rates of 12-month TD among ever-smokers in men showed no significant difference between 51.6% in 1984 and 50.6% in 2001. On the contrary, the rates in women significantly increased from 33.3% in 1984 to 52.8% in 2001. After adjusting for the sociodemographic variables, ‘male gender’ was significantly associated with 12-month TD among eversmokers in 1984, but not in 2001. ‘Unmarried’ was significantly associated in 2001 but not in 1984. ‘Alcohol dependence’ was the only psychiatric disorder associated with 12-month TD in both study years. In conclusion, 12-month TD was found in about 50% of ever-smokers, and gender differences between the rates of 12-month TD which was observed in 1984 disappeared in 2001. Individuals with 12-month TD showed higher comorbidity with alcohol dependence than ever-smokers without TD.

In this study, the structure and properties of waste oyster shell and its phosphorus removal efficiency were investigated. Waste oyster shells are troublesome environmental waste in the coastal region where the oysters are produced. Waste oyster shells were pyrolyzed by bench-scale rotary kiln for its activation. It shows maximum 76% of phosphorus removal efficiency for the municipal wastewater and livestock wastewater. We found that the activated oyster shells can be used as a phosphorus removal agent with the consideration of high efficiency, easy processing, and cost effectiveness.

마산만유역의 창원시 수계에서 발생한 오염부하는 차집관로를 통하여 하수종말처리장으로 운반되거나 창원시 하천을 거쳐 봉암갯벌을 경유한 후 마산만으로 유입된다. 즉 마산만 하구 갯벌인 봉암갯벌은 도심에 위치하여 있고 민관산학의 협력으로 보존되어 생태학습장으로 이용되는 귀중한 갯벌이다. 특히 최근 몇 년 동안 조개류, 어류와 물새 등 다양한 생물이 관찰되고 있으며 우리나라 최초의 마산만특별관리해역 연안오염총량관리의 중심 지역에 해당한다. 1970년에 시작한 창원기계공업단지의 가동으로 마산만의 하구와 내만은 중금속으로 오염되었음이 보고되었다. 봉암갯벌의 저서생물의 서식지인 퇴적물에 존재하는 잔류성이 강한 주요 중금속 오염물질의 변화를 분석하였다. 아연, 구리, 납이 오염퇴적물 기준의 상위 기준 또는 심한 오염 기준을 초과하였고 인근 지점별로도 95% 신뢰구간에서 차이를 보였다. 2006년과 2009년의 자료를 비교할 때 모든 중금속 농도가 점차 감소하고 있었다.

Background: Panic disorder (PD) and major depressive disorder (MDD) can occur concurrently, despite different clinical manifestations. Because MDD and PD patients tend to have more complicated conditions, understanding the co-occurrence and pattern of these conditions is important. Here, we investigated the influence of PD and MDD on each other, with respect to time interval. Methods: Data from three national representative surveys were pooled (total 18,807 respondents), and the age of onset (AOO) of PD and MDD was analyzed. We performed Kaplan-Meier analysis to estimate separate survival functions, using the AOO of MDD and PD as the outcome. To understand the temporal effect of other disorders, we used a Cox proportional hazard model to estimate the hazard ratios for the onset of MDD/PD with other comorbidities as time-dependent covariates. Results: PD elevated the risk of subsequent MDD by 1.5-fold, whereas MDD elevated the risk of subsequent PD by 3.8-fold. The effect of such an elevation risk was significant for up to 2 years. Conclusion: The results revealed a bidirectional relationship between MDD and PD. Each disease represents a risk of a subsequent occurrence of the other, which lasts for a considerable duration.

In this paper, circular polarized 2x2 truncated patch array antenna for GPS system is designed. Proposed 0.8λspacing 2x2 elements are fed by uniform feeding network, and have left handed circular polarization by truncation on side edges to each patches. Epoxy substrate, 1.2mm thickness and 4.75 relative dielectric constant with 0.019 loss tangent, is used to fabricate. Theoretical and tested characteristics as return losses, antenna impedances and radiation patterns on the 1.575GHz center frequency are shown. Measured results are agreed well with theoretical values.
