Objectives: Although there have been several reports that described characteristics for young age stroke, information regarding very young age (18–30 years old) has been limited. We aimed to analyze demographic factors, stroke subtype, and 3-month outcome in acute ischemic stroke patient who have relatively very young age in multicenter stroke registry. Methods: We evaluated all 122 (7.1%) consecutive acute ischemic stroke (within 7 days after symptom onset) patients aged 18 to 30 from 17,144 patients who registered in multicenter prospective stroke registry, 1997 to 2012. Etiology was classified by Trial of Org 10172 in Acute Stroke Treatment criteria. Stroke severity was defined as National Institutes of Health Stroke Scale (NIHSS) and stroke outcome was defined by modified Rankin scale (mRS) at 3 months after index stroke. Results: The mean age of all included patients was 25.1±3.7 years and 76 patients (62.2%) were male. The median NIHSS at admission was 4. Considering stroke subtype, 37 patients (30.3%) had stroke of other determined etiology (SOD), 37 (30.3%) had undetermined negative evaluation (UN) and 31 (25.4%) had cardioembolism (CE) were frequently noted. After adjusting age, sex and variables which had P<0.1 in univariable analysis (NIHSS and stroke subtype), CE stroke subtype (odds ratio, 4.68; 95% confidence interval, 1.42–15.48; P=0.011) were significantly associated with poor functional outcome (mRS≥3). Conclusion: In very young age ischemic stroke patients, SOD and UN stroke subtype were most common and CE stroke subtype was independently associated with poor discharge outcome.

연구목적: 본 연구는 물질사범에게 시행되는 수강명령 프로그램의 효과를 재범률을 중심으로 살펴보고자 한 것이다. 방 법: 이 연구의 대상집단은 보호관찰소에서 의뢰받은 물질남용자집단이다. 이들은 법원으로부터 보호관찰, 수강명령, 치료명령, 사회봉사 등을 부과받았다. 총 104명의 대상자집단을 치료프로그램을 이수한 수강군과 비수강군으로 나누었으며 이들에 대한 재범률을 조사하였다. 결 과: 프로그램을 이수한 수강군이 비수강군에 비해 재범률이 낮았다(p<.05). 또한 단기 수강군과 장기수강군의 재범률의 차이를 조사하였는데 대상자 집단의 수가 적기 때문에 장기 수강군의 효과가 통계적으로 입증되지는 않았다. 결 론: 우리는 물질남용자에 대한 정책이 보다 교육적으로 변화할 것을 본 논문을 통하여 제시하려 하였으며 정부 및 법무부는 물질남용자에게 교육과 치료를 제공해주어야만 한다. Objectives: Using recidivism rate, we investigated the outcome after our substance abuse treatment program had been implemented. Methods: Our target population was substance abuse criminals referred by probational office. They either received the parole and probation order, treatment order or social service order from the court. We divided 104 substance abuse criminals into treatment group and non-treatment group. We examined their recidivism rate. Results: We reached a conclusion that treatment group had lower recidivism rate than non-treatment group(p<.0.5). We examined the effectiveness of short-term and long-term programs. However, no effectivess of long-term program was found because the sabject number was too small. Conclusion: We suggest that the strategies for substance abuse should be changed to more educative ones. The Government and Ministry of Justice must provide education and treatment to the substance abuse criminals.

이 논문은 자본시장에서 기업배당 공시의 진실성에 대한 시장의 평판과 배당의 미래 수익에 대한 신호 효과를 동시에 고려하는 경영자의 투자-재무 의사결정을 기업가치 극대화 모형을 통해 분석하고 있다. 주식 발행시 정보 비대칭성으로 인한 레몬 프리미엄을 부담하는 상황에서, 경영자는 배당률 인상에 따른 발행주가 상승의 이익과 신호에 따르는 평판 변화의 효과가 한계적으로 일치하는 수준에서 최적 배당률을 결정한다. 정보의 비대칭성 및 경영자가 시장을 속일 수 있는 기능성의 존재로 인해, 합리적 기대 균형하의 시장 주가는 완전정보일 때에 비해 더 낮게 형성되며 그 영향으로 과소투자가 이루어지게 된다. This paper develops a model that corporate managements try to maximize incumbent equityholders' wealth in asymmetrically informed capital markets, where firms should bear lemons premium at issuing stocks and dividends has announcement effect on the corporate future cash flow. A corporate manager should consider the marginal increase of stock price and the marginal change of its reputation when increasing cash dividends. When s/he increases dividends, outside investors doubt whether it is true or false signaling. Because of lemons premium and probability of investors being cheated by false signaling, equilibrium stock price formed through rational expectations turns to be set below that of perfectly informed capital markets. It results in underinvestment. That is, corporate investment is done less than the Fisherian optimum level of investment. The better reputation in its truthfulness of announcement a firm has, the less cost due to the problem of time inconsistency it could bear.

Various cytokines including IL-1β, IL-2, IL-4, IL-10, IL-12p40, IFN-r, and TNF-α have been recently reported to play important roles in both host and donor cell activations during xenotransplantation. Interleukin (IL)-18, a proinflammatory cytokine, can induce IL-4 and IL-13 production in T cells, NK cells, B cells, mast cells, and basophils. IL-18 has the capacity to stimulate innate immunity and both Th1-and Th2- mediated responses, but little is known to involve in the xenograft rejection. In order to investigate the role of IL-18 in xenograft rejection, we transplanted the pig kidney (PK15) cells to C57BL/6 mouse with or without intraperitoneal injection of mouse recombinatant IL-18, It was analyzed the population of T cell, B cell and NK cell in the mice transplanted with PK 15 cells and recombinant IL-18 by flow cytometry. We found that splenic CD3+ T cells were increased in mice injected PKl5 cells with recombinant IL-18. These results suggest that recombinant IL-18 is critical in the xenograft rejection by increasing T cell population of the recipients.

2006년 국내 각 지역으로부터 수집된 재래종옥수수 유전자원을 관행방법에 의해 파종하고 주요특성별로 분포도를 살펴본 결과는 다음과 같다. 1. 수집된 유전자원에 대한 발아율은 대부분 80∼100%이상의 분포를 보였으나, 일부 수집계통에는 30% 미만의 극히 저조한 발아율을 보였다. 2. 수집자원에 대한 초기생육을 살펴보면 극히 생육이 저조한 것이 40% 정도를 보였고, 극히 우수한 자원은 3%미만으로 나타났다. 3. 간장은 대부분이 150∼199cm범위에 55%가 분포하고 있었으나, l00cm이하가 5%, 250cm이상이 8%로 나타나 수집종간에 큰 차이를 보였다. 4. 주당 분얼수는 1개 미만이 40%의 분포를 보였으나, 일부 수집종에서 2 내지 3개의 분얼수를 보이는 계통이 확인되었다. 5. 개화소요일수는 61∼64일의 범위에서 40%, 57∼60일의 범위에서 30%의 분포를 보였으며, 특히 일부 수집종의 경우 55일 이하의 극조생종도 10% 정도의 분포를 보였다. 6. 이삭길이는 대부분 11∼15cm범위에 60%가 포함되어 있으나, 일부계통에서 5cm미만이 2%, 16∼20cm의 이삭길이도 10%가 분포하였다. Germination ratio on the 300 collected genetic resources showed 80 to 100 percentage, but those of some accessions were very low as below 30 percentage. Early growth phase of most of these lines were very poor while some collected lines were very vigor. Range of stem height showed from 150 to 199cm, but that of some accessions showed below 100cm as five percentage and some of them was over 250cm as eight percentage. Number of tillers per plant appeared less one but some collected lines have two to three tillers per plant. In days to tasseling, some accessions showed more four per plant. Ear length of these accession showed above 60 percentage as 11 to 15cm, while that of some collected lines showed over 10 percentage as 16 to 20cm.

Cell proliferation in the developmental sequence of fore-limb in the DDY mouse with the adverse effect of single dose of etretinate (Tigason®) on it correlated to the drug-induced dysmorphogenesis was studied by measns of argyrophil technique for nucleolar organizer regions(AgNORs) and expression of proliferating cell nuclear antigen(PCNA). The number of AgNORs per nucleus displayed regional differences in the limb bud on day 11 of gestation, as higher values in apical ectodermal ridge(AER) and growing tip but decreased rapidly thereafter compared with those in the other parts of epithelia and subepithelial mesenchyme, while in core mesenchyme where the higest in its value on day 11, the numbers decreased depend not on the age but on the chondrified stage specific. Antibody reaction to PCNA expressed in almost all of the cells, stronger in mesenchyme than in epithelia on day 11 and then decreased gradually with the development proceed. Siver reactions to NORs as well as PCNA expression were decreased sharply by etretinate but recovered gradually from 24 hours after treatment except the value of AgNORs in the chondrified mesenchyme. The results Indicate that growth conducted by AER with subridge mesenchyme and chondrification in the core mesenchyme are two of major processes in the early development of limb, and the adverse effects of etretinate on proliferation and differentiation persist longer in the chondrified area but decreased expression of proliferative activities by the drug do not appear to be the result subsequent to the drug-induced cell death. The results suggest that temporal inhibition or interruption of the proliferation could deprive the programmed sequence of development of its appropriate timing with subsequent disturbance of the pace in growth which might be a role of limb dysmorphogensis but the drug's affinity to the chondrified cells remains a question.
