This study was performed to examine the relationship between air pollution exposure and mortality in Seoul for the years of 1998~2001I. Daily counts of death were analyzed by general additive Poisson model, with adjustment for effects of seasonal trend, air temperature, humidity, and day of the week as confounders in a nonparametric approach. Daily death counts were associated with CO (current day), 0₃(current day), PM_(10) (current day), NO₂, (1 day before), SO₂, (1 day before). Increase of 41.711㎍/㎥ (interquartile range) in PM_(10) was associated with 1.3% (95% CI = 0.7~1.9%) increase in the daily number of death. 0₃concentrations resulted in an increased risk of 1.3% for 23.86 ppb in all-aged mortality [RR = 1.013 (1.004-1.023)]. This effect was greater in children (less than 15 aged) and elderly (more than 65 aged). After ozone level exceeds 25 ppb, the dose-response relationship between mortality and ozone was almost linear. We concluded that Seoul had 1~5% increase in mortality in association with IQR (interquartile range) in air pollutants. Daily variations in air pollution within the range currently occurring in Seoul might have an adverse effect on daily mortality. These findings also support the hypothesis that air pollution, at levels below the current ambient air quality standards of Korea, is harmful to sensitive subjects, such as children or elderly.

본 논문은 CHILL 언어에 정의된 병행처리 기능을 실행시키기 위해 설계한 Run-time 시스템[8]의 프로세스 관리 구조 및 언어 인터페이스 규격에 관한 연구이다. CHILL Run-time 시스템은 기계 독립적인 부분과 기계 종속적인 부분으로 구성되는데 기계 독립적인 부분의 프로세스를 관리하기 위하여 ready, event, buffer, signal, region 큐가 사용된다. 이들의 구조와 C언어와의 언어 인터페이스 규격에 관한 사항을 제시한다. In this paper, we present the process management structure of run-time system[8] which we have designed to execute the concurrent processing facilities of CHILL language definition and have described the language interface specifications on the run-time system. The CHILL run-time system is consisted of the machine independent parts and machine dependent parts. To manage the processes in the machine independent parts is made use of queues(ready, event, buffer, signal, and region queue). We suggest the structure of these queues and the language interface specification with C language.

병행 처리를 위한 CHILL 언어 Run-time 시스템의 설계

조철희,하수철 大田大學校 産業技術硏究所 1996 산업기술연구소 論文集 Vol.7 No.2

본 논문에서는 병행 프로그래밍 언어에서 제공되고 있는 병행 처리 기능을 실행시키기 위한 Run-time 시스템의 설계에 관한 연구를 기술하고 있다. 대상 언어는 ITU-T에서 통신처리 시스템용 프로그래밍 언어로 표준화된 CHILL이다. 이 언어는 다른 병행 프로그래밍 언어에 비해 다양한 병행 처리 기능들을 제공하고 있기 때문에, 이에 대한 병행 처리 Run-time 시스템의 설계는 병행 처리를 위한 주요 기능들과 기법들을 획득할 수 있는 효과를 얻을 수 있다. 이를 위하여 CHILL 컴파일러와의 정합을 위한 병행 처리 기능의 인터페이스 규격을 설계하며, 다른 컴퓨터 시스템으로의 이식성을 높이기 위해 기계 종속적인 부분을 최소화하도록 설계한다. 또한, Run-time 시스템의 병행 처리 프리미티브를 프로시듀어 호출 형식으로 사용할 수 있는 라이브러리 방식의 설계 방안을 제시한다. This paper presents the design of run-time system that supports the execution of concurrent processing facilities of concurrent programming language. The target language is the CHILL(CCITT High Level Language) that was recommended by ITU-T(International Telecommunication Union Telecommunication Standardization Sector). Because the CHILL programming language provides many various concurrent processing facilities as compared with other concurrent programming language, we can get some real effect about the major functionality and the techniques for the concurrent processing through a design of the CHILL run-time system. To implementing the CHILL run-time system, we design the interface rule between the CHILL compiler and the run-time system, and we minimize the machine dependent part of the run-time system in order to increase the portability. We also suggest the design concept for the concurrent processing primitives of the run-time system which can be invoked by procedure call.

본 연구는 원예치료와 미술치료가 학교부적응 청소년의 자아개념, 내적 통제력, 불안감소에 미치는 영향을 조사하고자 실시되었으며, 그 결과는 각 치료의 효과성이 비교·분석되었다. 인천 남구에 위치한 W공업고등학교에서 대조군 15명, 원예치료군 15명, 미술치료군 15명을 주 2회씩 2001년 9월 27일부터 12월 13일까지 원예치료군에는 원예치료 프로그램을 미술치료군에는 미술치료프로그램을 실시하였다. 원예치료 및 미술치료는 각각 전문 치료사에 의해서 행해졌다. 원예치료 및 미술치료 프로그램의 효과를 알아보고자 자아개념(Self-Concept Scale), 내적 통제력 척도(Inner-Control Scale), 특성불안 척도(Trait-Anxiety Scale)을 각 프로그램의 실시전과 실시후로 조사하여 비교하였다. 원예치료군에 있어서는 자아개념척도 중 자아수용, 성격적 자아, 총 자아 긍정 항목에서 통계적으로 유의한 향상을 보였고, 특성불안척도에서는 우울 및 불안 항목에서 매우 유의한 감소를 나타내었다. 한편, 미술치료군에 있어서는 내적통제력과 특성불안척도중 자신감이 유의하게 향상된 것으로 나타났다. 이상의 결과를 종합하여 볼 때, 원예치료군은 프로그램 과정중 자기표현의 기회를 제공함으로써 자아개념이 향상되었으며, 또한, 공동작업을 하는 집단 프로그램을 통하여 내면의 불안과 갈등이 완화되었다고 판단된다. 반면, 미술치료군은 치료자와의 개인적인 상담과정을 통하여 내면의 불안과 갈등이 완화되었고, 지점토 및 칼라믹스 만들기 등 활동적인 프로그램을 통하여 내면의 감정을 통제하는 능력이 향상되었다고 판단된다. This study was conducted to evaluate the effect of HT (horticultural therapy) and AT (art therapy) on the changes of self-concept, inner control, trait anxiety of the school maladjusted adolescents. 45 school maladaptive of teenage students participated in therapy program at the W high school were randomly assigned to 3 groups: 15 for the horticultural therapy, 15 for art therapy, 15 for control group. The program were carried out from Sep. 27 to Dec. 13, 2001 as an activity group. Activity group attended twice a week for 1 hour. For evaluation of the effectiveness of each therapy, Self-Concept Scale, Inner-Control Scale, Trait-anxiety Scale were used 2 times, that is, before/after HT or AT program. According to the results, self satisfiction, personal self, and total positive self items among Self-Concept Scale were significantly improved, and tension and anxiety item among Trait anxiety Scale were significantly decreased in HT group. On the other hand, in AT group, both inner control and self confidence item in Trait-anxiety Scale were significantly improved. In conclusion, in HT group it was suggested that the improvement of self concept could be brought about by being provided the chance of self expression during program and the alleviation of inner anxiety and discord resulted from group therapy program in which joint work have been provided. In case of AT group, it was logically postulated that the alleviation of inner anxiety and discord resulted from personal counselling with AT therapist during program and the improvement of inner control was caused by active program such as painting paper clay, making color mix, and etc.

Inhibitory Effect of Clavicepitaceae on Serotonin Release out of Human Platelets and Human Platelet Aggregation

박화진,--,--,--,--,--,-- THE KOREAN SOCIETY FOR BIOMEDICAL LABORATORY SCIEN 2004 Journal of biomedical laboratory sciences Vol.10 No.1

We have investigated the effects of hypha-water extracts (HWE), fruit body-water extracts (FWE) and cordycepin from Cordyceps militaris on serotonin release out of human platelets and human platelet aggregation. HWE and FWE inhibited the release of [^(3)H]-serotonin from human platelet stimulated by thrombin (2 U/ml) or collagen (20 ㎍/ml) in a dose-dependent manner. Furthermore, cordycepin, a major component of Cordyceps militaris, inhibited the human platelet aggregation induced by collagen (10 ㎍/ml) in a dose-dependent manner. These results suggest that cordycepin containing in HWE and FWE may inhibit the serotonin release by suppressing the collagen-induced human platelet aggregation. Accordingly, our data demonstrate that HWE and FWE containing much cordycepin might have antithrombotic and antimigrainous functions.

To determine the characteristic double contrast barium enema findings of ileo-cecal and colonic tuberculosis and to make differential diagnosis from other bowel inflammatory disease. Sixty-seven patients confirmed as ileo-cecal and/or colonic-tuberculosis in six hospitals were evaluated retrospectively. The diagnosis was proven by endoscopic biopsy, surgery, and clinical follow up. Nine of 67 patients were excluded because radiologic findings were normal though endocopic biopsy examinations resulted in tuberculosis. Histopathological diagnosis were madein 58 cases as follows: endoscopic biopsy(n=29), operation(n=12), follow up examination(n=14), tissue culture(n=1), laparoscopic biopsy(n=2). There were 30 men and 28 females. The mean age were 36 yrs(range:16-67), 34 patients were in the second and third decade. The distribution of lesions, morphological characteristics, mucosal changes, ulcer shape and depth, associated with other tuberculous lesion, multiplicity were retrospectively analyzed in the findngs of double contrast barim enema. The commonest clinical symptoms were abdominal pain(n=35, 60%) and diarrhea(n=18, 31%). The chest radiography revealed association of pulmonary tuberculosis in 39 cases. Tuberculous lesions of other organs except chest were present in five cases. Double contrast barium enema findings showed a thickening and irregularity of intestinal mucosal fold(n=29, 50%), bowel contraction and/or shortening(n=26, 45%). There were small, nodular, superficial ulcers in the case of ulcer depth less than 2 mm in the depth. As many as 39 cases(67%) in this series had two or more lesions in the intestinal tuberculosis. The involved segment revealed symmetrical feature(n=21, 36%). Inflammatory pseudopolypoid lesions were noted in 30 cases(52%). The ileo-cecal region was involved in 38 cases(66%). The ascending colon(n=25, 43%) was the second commonest site with or without contiguous cecal involvement. Lesions in terminal ileum, ileo-cecal valve, transverse colon, descending colon and appendix were seen in 19, 18, 18, 12 and seven cases, respectively. Among 18 cases of ileo-cecal valve lesions, there were incompetency in nine cases(16%) and wide gapping in four cases(7%). In 14 cases, tuberculous enterocolitis was diagnosed by clinical follow-up and double contrast barium enema study. 12 out of 14 cases, the findings of double contrast barium enema of tuberculous enterocolitis were normalized after anti-tuberculous medication. However, two cases showed more aggravated state than before due to inappropriate treatment. Double contrast barium enema plays an important role in the diagnosis of tuberculous enterocolitis, determines the type, site and extent of the involvement and helps in treatment guide by using sequential studies.

( Hye One Kim ),( Soo Ick Cho ),( Jin Hye Kim ),( Bo Young Chung ),( Hee Jin Cho ),( Chun Wook Park ),( Cheol Heon Lee ) 대한피부과학회 2013 Annals of Dermatology Vol.25 No.2

It is well known that atopic dermatitis (AD) is related to food hypersensitivity, although its prevalence varies among several studies according to age group, severity, country, survey time, and test method. Objective: To examine the prevalence and status of food hypersensitivity among childhood AD patients in Korea. Methods: A total of 95 patients were enrolled in the study. The history of food hypersensitivity was collected by interviews. The severity of AD was evaluated by eczema area and severity index (EASI). We took blood samples to measure serum total and food-specific immunoglobulin E (IgE) levels. Based on the histories and serum IgE levels, open oral food challenge (OFC) testing was performed to confirm food hypersensitivity. Results: Forty- two (44.2%) of the 95 AD patients had histories of food hypersensitivity. They reported that the most common suspicious foods were egg (n=13, 13.7%), pork (n=9, 9.5%) and cow milk (n=8, 8.4%). The mean EASI score was 16.05±9.76. Thirty-nine (41.1%) of the 95 patients showed elevated serum food-specific IgE levels. The specific IgE levels were elevated for egg (n=17, 17.9%), milk (n=12, 12.6%), peanut (n=10, 10.5%) and wheat (n=8, 8.4%). Fifty-one (53.8%) of 95 patients underwent open OFC, and only 7 (13.7%) of these patients showed positive reactions. Conclusion: The overall prevalence of food hypersensitivity in patients with childhood AD in Korea was 8.3% (7/84). The most common foods causing food hypersensitivity were egg and milk. Among the foods causing hypersensitivity, AD patients in Korea often underestimated peanut, while they overestimated pork.
