김포시와 고양시 일대의 한강하구 지역은 우리나라에서 재두루미의 가장 중요한 월동지 및 중간기착지로 알려져 있지만, 이 지역의 조류 서식환경은 심각한 개발압력과 인간의 간섭으로 인해 지속적으로 나빠지고 있다. 따라서 본 연구에서는 2007-2008년과 2011-2012년의 월동시기에 본 지역에 도래하는 재두루미를 대상으로 월동 개체군 크기 변화와 월동지역 내에서 과거와 현재의 취식지역 이용 현황 등을 조사하여 개발행위가 이들의 서식에 미치는 영향을 확인하였다. 본 지역에서 월동하는 재두루미 개체군은 평균 124.9개체(2007-2008년)에서 59.0개체(2011-2012년)로 감소하였으며, 주요 취식지역에서 확인된 개체수는 평균 77.7개체에서 24.1개체로 감소하여 월동개체군의 감소폭에 비해 주요 취식지역의 이용 개체수의 감소폭이 더 크게 나타났다. 유형별 분석에서는 가족군에 비해 무리군의 개체수가 많이 감소한 것으로 나타났으나, 홍도평 지역의 가족군 이용 개체수는 변화가 나타나지 않았다(Mann-Whitney test. Z=-0.26, p=0.979). 그리고 과거 다수의 재두루미가 주요 취식지역으로 이용하였던 송포동과 평동지역은 2012-2013년 조사에서는 거의 이용하지 않는 것으로 나타났다. 이는 위 지역의 개발행위(예: 제 2자유로 건설 등)와 깊은 연관성이 있는 것으로 생각된다. Han-river estuary in Gimpo and Goyang city is well known as one of the most important wintering and stopover sites for migrating White-naped Crane (Grus vipio) in Korea. Nowadays, habitat quality of this area is getting worse due to serious development pressure and high human disturbances. So, we wanted to know whether development actions affected total wintering population change in Han-river estuary and feeding group pattern of White-naped Crane in main feeding habitats between the 2007-2008 and 2011-2012 wintering period. Average wintering population was decreased 124.9 to 59.0 and population of main feeding site also decreased 77.7 to 24.1. But decrease rate of main feeding site population was higher than total wintering population. Non-family feeding population was more decrease than family feeding population in the flock type analysis. But family feeding population of Hongdopyong was maintained from past and present (Mann-Whitney test. Z=-0.26, p=0.979). However, almost all White-naped Crane din not use both feeding sites, Pyong-dong and Songpo-dong, where were deteriorated habitat quality by human act.

Purpose: The purpose of this study was to understand the degree of depression, sleep quality, job stress and their association among office workers. Method: A self-administered questionnaire was distributed to 147 workers employed in 5 big enterprises, and 5 small and medium enterprises from October 21 to November 21, 2012. The questionnaires included socio-demographic and health-related characteristics, job-related characteristics, sleep quality, job stress (KOSS) and depression (CES-D). Result: Among all subjects, 23.1% was in the depression group (21 points and over in the CES-D score). Depressive level was positively correlated with job stress and quality of sleep. The adjusted odd ratio for the effects of sleep quality and job stress on depression significantly increased in the depression group compared to that of the normal group. Multiple regression analysis revealed that the following factors of influence had combined explanatory powers on depression: BMI, life satisfaction, quality of sleep, and job stress. Conclusion: The study revealed that complicated influences were exerted on the level of depression by variable factors, as well as socio-demographic characteristics, health-related characteristics, quality of sleep, and job stress. Specifically, the level of depression was influenced by the quality of sleep and job stress.

Brand advertisement can be effective when they can communicate with the customers who can share the culture and trend expressed through the advertisement. Therefore, the advertisers should be well aware of the possible target customer of the brand. Furthermore by making an advertisement that parallels cultural codes of the customers', it will be able to attract attentions from potential customers. This research analyzed the consumer culture positioning trends incorporated by female casual brands magazine advertisements, and examined the periodic changes and preferred colors for each different positioning type for the past five years. 345 magazine advertisements were classified into foreign consumer culture positioning and local consumer culture positioning types. Among the colors expressed in the advertisement, the color that occupied the largest visual area was selected as the main color of the advertisement. After chosen, the color was analyzed by Munsell's 10 hues and 12 tone classifications of PCCS (Practical Color Coordinate System). Ad with foreign consumer culture positioning counted for 281 taking the dominant portion, whereas local consumer culture positioning ad accounted for only 64. There were brands that implement culture positioning techniques than other brands. The 20 brands frequently applied foreign consumer culture positioning in their advertisements. The most frequently used hue was Red. Purple Blue was also common. In terms of value and intensity, dark grayish tone was also most commonly incorporated.

For elucidation of various parameter's effect on the reactive extraction of organic acidstrioctylamine(TOA)-diluents system, the association model, equilibrium constants and extraction factors(loading) were investigated . The organic acids rosed were propionic. succinic, masonic, and benzoic acid. Extractant was tertiary amine, TOA and diluents were butylaeohol, hexane, and benzene. It was concluded that the loading of monobasic acid of propionic acid were higher than that of dibasic acids of oxalic, and malonic acid with extranctant TOA. In the extraction of monobasic acid the extraction factor was not affected by the initial concentration of extractant amine, but in the extraction of dibasic acids the extraction factor was getting better with decreasing the initial concentration of amine. There was a strong effect of diluents upon the extractien factor, and the order of these factor was as shown below: xylene<Benzene<butylalcohol<choloroform<methylisobutylketone.

목적 : 본 연구는 ESBL을 생성하는 K. pneumoniae에 의한 균혈증 환자에서 감염의 위험 인자 및 치료 결과를 알아보고자 시행하였다. 방법 : 1998년 1월부터 2002년 4월까지 혈액 배양 검사에서 동정된 K. pneumoniae를 대상으로 NCCLS guidelines과 이중 디스크 확산법(double-disk diffusion test)을 이용하여 ESBL 생성 여부를 확인하였다. ESBL 생성 균주에 의한 균혈증 환자 60명(환자군)에 대해 ESBL을 생성하지 않는 균주에 의한 균혈증 환자들(대조군)을 연령, 성별, 균혈증 발생 시점을 고려하여 1:2 또는 1:3으로 배정하였다. 총 159명의 대조군을 선정하였고 후향적인 환자-대조군 연구를 시행하였다. 결과 : 환자군과 대조군 사이에 연령, 성별, APACHE Ⅱ score, 주된 감염 부위의 유의한 차이는 없었다. ESBL을 생성하는 K. pneumoniae에 의한 균혈증이 발생할 독립적인 위험 인자에는 요관 삽입, 균혈증 발생 이전 72시간 동안 침습적인 시술을 받은 경우, 균혈증 발생 이전 30일 동안 투여받은 항생제 개수가 있었다. 초기 항생제 치료 72시간 후의 반응을 평가하였을 때, 완전 반응(complete response)은 대조군에서 더 많았고(13.3% vs. 40.3%, P<0.001), 치료 실패(treatment failure)는 환자군에서 더 많았다(33.3% vs. 11.9%, P<0.001). 7일 사망률은 환자군에서 20% (12/60), 대조군에서 15.6% (25/159)이었고(P=0.451), 30일 사망률은 환자군에서 30% (18/60), 대조군에서 24.5% (39/159)이었다(P=0.410). ESBL 생성 균주에 의한 균혈증이 있는 환자들에서 최종 항생제 치료가 부적절했던 환자들을 제외하고 30일 사망률을 분석하였을 때 효과적인 항생제 치료의 지연은 사망률을 높이지 않았다(11.1% vs. 9.1%, P=1.000). 결론 : ESBL을 생성하는 K. pneumoniae에 의한 균혈증이 있는 환자에서 초기 항균제 치료 72시간 후의 치료 반응률은 낮지만 사망률은 유의하게 증가하지 않았다. 원인균이 동정된 후 최종 치료 항생제의 선정이 적절하다면 초기에 효과적인 항생제 투여의 지연은 사망률을 유의하게 증가시키지는 않았다. Background : This study was conducted to evaluate risk factors for infection and treatment outcome of bloodstream infection due to extended spectrum β-lactamases(ESBL)-producing K. pneumoniae. Methods: ESBL production was evaluated by NCCLS guidelines and/or double-disk synergy test in K. pneumoniae blood isolates stored from January, 1998 to April, 2002. Sixty patients with bloodstream infection due to ESBL-producing K. pneumoniae (case patients) were compared with 159 matched control patients with bloodstream infection of non-ESBL-producing K. pneumoniae. Retrospective case-control study was performed. Results : There were no significant differences in age, sex, APACHE Ⅱ score, and the primary site of infection between the case and control groups. In multivariate analysis, significant independent risk factors associated with bloodstream infection due to ESBL-producing K. pneumoniae were urinary catheterization, invasive procedure within previous 72 hours, and the number of antibiotics administered within previous 30 days. In clinical response at 72 hours after initial antibiotic treatment, complete response rate was higher in the controls (13.3% vs. 40.3%, respectively, P<0.001), however, treatment failure rate was higher in the cases (33.3% vs. 11.9%, respectively, P<0.001). Overall 7-day mortality rates in the cases and the controls were was 20% (12/60) and 15.7% (25/159) (P=0.451), respectively, and overall 30-day mortality rates were 30% (18/60) and 24.5% (39/159), respectively (P=0.410). When the patients with bloodstream infection of ESBL-producing organism were evaluated and the patients who received inadequate definitive antibiotic treatment were excluded, delayed effective antibiotic treatment was found to be not associated with higher mortality. Conclusion : In patients infected with ESBL-producing K. pneumoniae bacteremia, clinical response rate at 72 hours after antimicrobial therapy was lower, but the increase of mortality rate was not significant. Delayed effective antibiotic treatment was not associated with higher mortality, when definitive appropriate antibiotic treatment was prescribed.

Autosomal dominant polycystic kidney disease(ADPKD) is one of most common hereditary disorder. It is potentially fatal and the major mobilities are hypertension and renal failure. To elucidate clinical characteristics and outcomes of ADPKD, 67 ADPKD patients were analyzed retrospectively. The male to female ratio was 48 years for males and 42 years for females. The factors leading to the dignosis of ADPKD were flank or abdominal pain (46%), palpable abdominal mass (24%), incidental findings (18%), gross hematuria and headache. Urinalysis result showed hematuria (31%), proteinuria (19%), pyuria (18%). Among renal complications hypertension (67%) was the most common. Other complications were urolithiasis (16%) upper urinary tract infection (9%), cyst infection (7%). Azotemia was observed in 24% of cases. Echocardiography showed left ventricular hypertrophy in 24% and valvular regurgitation in 18% of cases, but there was no mital valve prolapse. Cerebrovascular events occurred in 6 cases (2 cases of intervertebral hemorrhage and 4 cases of cerebral infarction). Hipatic cyst were observed in 64% of cases. Eighteen cases culminated in end stage renal failure (ESRF) at an of 47. According to this study, the most common complications of ADPKD was hypertension (67%), ESRF (27%), and cerebrovascular event (9%). Hypertension was more frequently observed in increased creatinine group than normal.
