Aerosol mass size distributions were investigated at 865 m high the of Jirisan national park. A nanosampler cascade impactor was used to collect aerosols. The atmospheric aerosol particles had a unimodal mass size distribution, which peaked at 0.5-1.0 μm, and a mass aerodynamic diameter of 1.13 μm. The ann ual average concentrations of TSP, PM₁₀, PM_2.5, PM1, PM_0.5 and PM_0.1 were 20.9 μg/㎥, 19.3 μg/㎥, 14.9 μg/㎥, 10.7 μg/㎥, 5.3 μg/㎥, 1.2 μg/㎥, respectively. TSP concentrations were below 30 μg/㎥ during the sampling period. On average PM₁₀, PM_2.5, PM₁, PM_0.5 and PM_0.1 made up 0.91, 0.70, 0.41, 0.19 and 0.07 of TSP, respectively. The annual average of PM_2.5/PM₁₀ ratio was 0.77.

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.

This paper presents a back-end system of hypermedia authoring system for courseware development. For the design, repersentative hypertext reference models, the Dexter model and the HAM(Hypertext Abstract Machine) which belongs to Campbell & Goodman model were analyzed. Based on those models, data objects, attributes, and operations of back-end system were designed and implemented. Because the application area of this system is on computer based education, the path mechanism is enforced for the various educational strategies. In order to reduce the user disorientation and cognitive overheads in navigating hypernetwork, filtering, backtracking and history mechanism were implemented.

Objective: The purpose of this study was to evaluate the correlation between menton deviation and dental compensation in facial asymmetry. Methods: Tooth axis and distance of first molar and canine to the reference plane were investigated by cone-beam computerized tomography. The subjects consisted of 50 patients with asymmetric mandibles (male 21, female 29, mean age 24.3 years). Control groups were also assessed (male 11, female 9, mean age 25.6 years). Nine measurements (5 linear measurements and 4 angular measurements) were measured in order to evaluate the correlation between menton deviation and the linear and angular difference of first molar and canine in the deviated and none-deviated sides using the defined MPR images. The differences between deviated and non-deviated side, according to menton deviation, were statistically analyzed using stepwise multiple regression analysis. Results: From the result, Menton deviation was negatively correlated with mandibular first molar's angular measurement (Δ∠LM6-Mn plane (dev.-ndev.)) and positively with maxillary fist molar's angular measurement (Δ∠UM6-FH plane (dev.-ndev.)) (p < 0.01). Two angular measurements (Δ∠ LM6-Mn plane (dev.-ndev.), Δ∠UM6-FH plane (dev.-ndev.)) explained the variability in menton deviation with a significant r² value of 0.589. Conclusions: This study suggests that the tooth axis of upper and lower first molars leans towards the deviated side of Menton when there is mandibular asymmetry with Menton deviation. 본 연구는 Cone-beam CT의 MPR이미지상에서 하악골 평면에 대한 하악 제1대구치와 견치의 편위측과 비편위측의 높이와 각도차이 그리고 FH 평면에 대한 상악 제1대구치와 견치의 편위측과 비편위측의 높이와 각도차이를 계측함으로써 안면비대칭자에서 이부편위에 따른 편위측과 비편위측의 제1대구치와 견치의 높이와 협설측 경사도를 CBCT를 이용하여 분석하고 그 관련성을 알아보는 데 있다. 연구대상은 하악골의 이부편위를 동반한 안면비대칭 환자 50명(여자 29명, 남자 21명, 평균나이 24세 4개월)으로 하였다. 대조군으로 평균나이 25세 7개월인 20명(남자 11명, 여자 9명)을 분석하였다. 결과는 이부편위에 대해 FH 평면에 대한 상악 제1대구치의 편위측과 비편위측의 길이 및 각도 차이(편위측 - 비편위측)는 대조군에 대해 통계적으로 유의한 차이가 존재하였다 (p < 0.01). 비대칭군에서 상악 제1대구치 각도는 편위측이 비편위측보다 평균 8.62 ± 5.95˚ 컸다 (p < 0.01). 상악 견치의 경우에도 편위측과 비편위측의 각도차이가 평균 4.48 ± 5.05˚로 통계적으로 유의한 차이가 존재하였다 (p < 0.01). 하악골 평면에 대한 하악 제1대구치의 수직 길이와 각도는 편위측과 비편위측에서 통계적으로 유의할 만한 차이가 존재하였다 (p < 0.01). 각도의 차이는 평균 -11.92 ± 5.79˚로 나타났다. 이부편위에 대한 상하악 제1대구치와 견치의 수직거리 및 각도의 Pearson 상관분석 및 회귀분석 결과, FH 평면에 대한 상악 제1대구치의 편위측과 비편위측의 각도차이(Δ∠ UM6-FH plane (dev.-ndev.))는 통계적으로 유의한 양의 상관관계를 나타내었고, 하악골 평면에 대한 하악 제1대구치의 편위측과 비편위측의 각도차이(Δ∠LM6-Mn plane (dev.-ndev.))는 통계적으로 유의한 음의 상관관계를 나타내었다. 이상의 결과에서 이부편위를 동반한 하악골 비대칭이 존재하는 경우, 이부가 편위되는 방향으로 상하악 제1대구치의 치아장축의 각도가 변화되는 것으로 나타났다.

Background : Intravenous(Ⅳ) access is becoming an increasingly important part of health care today. The current drive for clinical effectiveness and cost-effective health care serves to increase the need for reliable vascular access. Venous access devices were developed to overcome problems associated with limited peripheral access and frequent venipuncture in patients with long-term therapy. Although the peripherally inserted central catheter(PICC) have become popular during recent years in USA, its procedure is rare in Korea. Purpose : The goal of this study was to analyze the PICC inserted patient data by Ⅳ CNS intervention. Method : A Total of 62 PICCs were inserted into 51 patients by the Ⅳ CNS during a 10-month period form November, 14, 2002, to October 2, 2W2. Data was obtained retrospectively through chart review. Result : The patient population included 34(54.8%) men and 28(45.2%) women, with a mean age 50.6 years. The main indication for PICC placement was to access vein in poor peripheral venous status(40.3%). The mean served interval for PICC insertions was 16.7 days(range, 2~61 days). The reasons for removal were completed therapy in 18 cases(29.0%), patient death in 13 cases(21.0%), and mechanical or functional PICC problem in 10cases(16.1%). The three PICCs removed for presumed infection, and one had only positive tip cultures(0.2%). Conclusion : PICCs are rapidly growing popularity and required an extended course of Ⅳ therapy.

만성 호중구성 백혈병 1예

Chronic neutrophilic leukemia(CNL) is a very rare myeloproliferative disease, characterized by sustained mature neutrophilic leukocytosis with granulocytic bone marrow infiltration, high NAP(neutrophilic alkaline phosphatase) score and absence of philadelphia chromosome, It is frequently accompanied by hepatosplenomegaly, elevated serum vitamin B_12 and uric acid level. For the diagnosis of CNL, the leukemoid reaction, especially secondary to neoplasia, infection and autoimmune diseases, should be excluded. Since Tuohy's first description in 1920, more than 50 cases fullfilling the above criteria have been reported worldwide, and 4 cases in Korea. Several authors have demonstrated the defect of intracellualr killing in the mature neutrophil and this finding correlates well with the very high incidence of fatal infection, The hemorrhagic diasthesis in CNL is caused by functional abnormality of the platelet. This disease has tendency to transform to blastic crisis and acute leukemia as in other myeloproliferative disease, but characteristically shows frequent coexistence with multiple myeloma. Until now , the therapeutic trials in CNL have been disappointing. Hydroxyrea and busulfan can control hyperleukocytosis. On the basis of functional defect in neutrophil, alpha-2b-interferon has been tried and several reports have demonstrated the clinical and functional effect of interferon on CNL. CNL is very rate hematologic disease and there are few report about general aspect of disorder. We report here a typical CNL case presenting with splenomegaly and leukocytosis with a review of the literature.

대학생을 위한 리더십향상 집단상담 구안 및 효과 연구

박현주,김민정,임진,엄혜련 西江大學校 學生生活相談硏究所 2005 人間理解 Vol.26 No.-

현대사회에서의 리더십은 크게 셀프리더십, 팔로워십, 능력부여리더십, 서번트리더십으로 분류될 수 있다. 한국의 대학생은 향후 인생의 목표를 설정하고 계획하여 추진하고 더불어 공동체의 일원으로 서로 교류하고 성장 한다는 발달적 과제를 가지고 있다. 따라서 대학생의 리더십은 셀프리더십을 바탕으로 한 자기관리, 대인관계 관리, 공동체 참여로 구성된다. 본 연구에서는 대학생의 리더십을 향상시키기 위한 집단상담을 구안하였으며 구조화된 대학생 리더십향상 집단상담을 2005년 1월에 실시하였다. 참여한 총 10명의 집단원들을 대상으로 집단상담 전 후에 각 구성요소를 측정하는 설문조사를 실시하였으며, 통계적으로 유의미한 차이는 아니었으나 자기관리, 대인관계관리, 공동체참여 각 영역 모두에서 향상된 양상을 보였다. 또한 집단원들의 회기별 피드백을 토대로 본 프로그램의 효과를 검증하였으며 본 프로그램의 보다 효과적인 적용을 위한 논의를 덧붙였다. Leadership, nowadays, can be classified into four different kinds: self-leadership, followership, empowering-leadership, and servant leadership. Korean university students have developmental tasks as members of group such as setting a life goal, making a plan, making an action, associating with others, and being advanced. Therefore, the elements of leadership program for university students based on self-leadership are self management, interpersonal relationship management, and participating in a group. In this study, a structured program for developing leadership of university students was designed, and operated on Jan, 2005. Surveys which measured each elements of the program were given to ten students who were participated in a group before and after the program. A statistical result was not significant. However, each elements, self management, interpersonal relationship management, and participating in a group, showed a progress. Session reviews by students were also used to verify the effect of the program. Further suggestions and studies for more effective application of the program were discussed.
