본 연구는 국악관현악단 활동이 중학생의 협동심과 음악적 자기효능감에 미치는 영향을 알아보는 것에 있다. 이를 위해 국악관현악단 활동이 이루어지고 있는 중학교 3곳을 대상으로 사전-사후 설문지와 포커스 그룹 면담을 진행하였다. 본 연구의 결과는 다음과 같다. 첫째, 국악관현악단 활동은 중학생들의 전반적인 협동심과 집단촉진, 팔로워십, 갈등문제해결의 3가지 하위 요소에 긍정적인 영향을 미쳤다. 특히 협동심의 하위 요소 중 집단촉진과 갈등문제해결의 요소가 학생들이 주체적으로 연습 과정에 참여하면서 노력하는 과정과 밀접한 관련이 있다는 점이 나타났다. 둘째, 국악관현악단에 참여한 학생들의 팔로워십 역량은 증가하였지만, 면담 분석 결과 집단의 목표가 명확하게 드러나지 않은 채 국악관현악단이 막연한 발전을 위해서 노력하는 모습으로 주로 나타났다. 셋째, 국악관현악단 활동은 음악적 자기효능감의 과제수준선호, 자기조절효능감, 자신감 세 가지 영역에 모두 긍정적인 영향을 주었다. 특히 학생들은 실력이 향상되고 작은 목표를 성취하는 과정을 통해 과제수준선호와 자신감 영역에서 긍정적인 영향을 받았다. 넷째, 음악적 자기효능감의 하위 요소 중 자기조절효능감은 협동심과 밀접한 연관성을 가지고 있다. This study aims to investigate the impact of Korean traditional orchestra activities on middle school students' cooperation and musical self-efficacy. To achieve this, a pre-post survey and focus group interviews were conducted in three middle schools where Korean traditional music orchestra activities were taking place. The results of this study were as follows. First, Korean traditional orchestra activities positively influenced middle school students' overall cooperation, including three sub-factors such as group promotion, followership, and conflict problem-solving. Particularly, it was observed that the elements of group promotion and conflict problem-solving within cooperation were closely related to students actively and independently participating in the practice proces. Second, followership skills of students participating in Korean traditional orchestra increased; however, the interview analysis revealed that the group's goals were not clearly defined. Third, Korean traditional orchestra activities had a positive impact on students' musical self-efficacy in terms of task preference, self-regulation efficacy, and confidence. Students particularly experienced positive influences in the areas of task preference and confidence through improving their skills and achieving small goals. Fourth, among the sub-factors of musical self-efficacy, self-regulation efficacy showed a close association with cooperation.

N/A Carcinoma of the lung is generally considered as a disease of middle age and elderly. But lung cancer is now so prevalent that patients below the age of 40 years must be increaseing. We reviewed the records of 483 lung cancer patients who had been diagnosed in the department of internal medicine of Seoul National University Hospital from March 1984 to February 1986, and the clinical features of the young patients under 40 years were compared with those of the control group patients over 40 years. The results are summarized as follows; 1) Seven percent of 34 cases of 483 patients were belong to the young age group patients (less than 40 years). The youngest patient was 22 years old. 2) Male to female ratios of young group and the control group were 3.25:1, 5.9:1 respectively (p>0.05). 3) The mean duration of symptoms from the onset to the definite diagnosis was 2.7 months in young group and 2.3 months in the control group (p>0.3). 4) The most common initial symptoms in the young group were dyspnea (26.5%), hemoptysis (20.5%), cough or sputum (20.5/), chest pain (8.8%) which were also the most common initial symptoms in the control group. (p>0.25) The incidence of superior vena cava syndrome was significantly higher in the young age group (23.5%) than in the control group (7.1%) (p<0.05). 5) In the young group, the proportion of adenocarcinoma (35%) was significantly higher than that of the control group (18%) (p<0.05). 6) The proportion of smoker was significantly lower in the young age group (13 cases, 38.2%) than in the control group (77.7%). The histological type of 13 smokers of the young group was squamous cell carcinoma in 12 cases and adenocarcinoma in 1 case. 7) All non-small cell lung cancer patients in young group were belong to stage III. 8) Distant metastasis rate of the young group (74%) was significantly higher than that of the control group (54.8%) (p<0.05).

The issue of binge drinking and alcohol abuse is a serious problem, which damages individuals and the society together with huge physical and mental prices. To increase the effects of public health campaigns, audience segmentation is required and sensation seeking with self-efficacy works as a key criteria for attitudes toward messages and behavioral intention in the context of risky behaviors such binge drinking. Besides personal characteristics, using appropriate appeals such as fear and humor also influences the audience`s decision-making process. This study suggested three variables, sensation seeking, self-efficacy and appeal types, intermingle together to influence attitudes toward campaign messages and behavioral intention. An experiment with 340 participants was conducted to answer the research questions and hypotheses. Sensation seeking and self-efficacy interacted only with the humor appeal against the message attitude. The message attitude was highly positive in the low sensation seeking and high self-efficacy group in both appeals. No interaction effects were detected between sensation seeking and self-efficacy against behavioral intention. Only main effects of sensation seeking and self-efficacy were found. Theoretical ramifications based on the results were discussed further.

다양한 cathode flow-field 설계를 통한 H₂O 유지 능력 향상을 위한 passive 공랭식 PEMFC

Two conceptional cathode flow field designs are proposed for preventing serious electrolyte dehydration and overcoming unstable performance issues in PEFC that are air-cooled passive type. In one design, porous metal foam is selectively inserted into the parallel channels in contact with the cathode gas diffusion layer to suppress water transport from the cell, and the other one has a smaller cathode inlet area to reduce the amount of reactant air entering the MEA. Compared with a conventional parallel flow-field configuration, the metal foam based design results in better water retention in the MEA when excess dry air is supplied. Furthermore, it shows more uniform distributions of species, temperature, current density, and higher cell performance. The modification of the cathode inlet area has a relatively small influence on performance of the fuel cell. This study presents a new strategy for designing the cathode flow field for the optimal operation of passive air cooled fuel cells.

Objective: To investigate whether the serum levels of IL-10 in patients with rheumatoid arthritis are different from those of normal controls and SLE patients and to find out any correlation with disease activity parameters of rheumatoid arthritis. Methods: Sera from 20 healthy normal persons, 16 rheumatoid arthritis patients and 16 patients with systemic lupus erythematosus were collected and measured for IL-10 and IL-6. Various disease activity parameters were measured in RA patients. Results: The serum level of IL-10 in RA patients was significantly elevated compared to normal controls but lower than those of SLE patients. In RA patients there was no definite correlation between the disease activity parameters and serum IL-10 levels. Despite significant improvements in terms of various disease activity parameters, there was no significant change of serum IL-10 levels after treatment in RA patients. In seropositive RA patients, positive correlation was found between serun IL-10 and rheumatoid factor levels. Conclusion: Our findings show that the serum IL-10 levels in patietns with RA are elevated compared to normal controls but lower than those of SLE patients. There was no correlation between serum IL-l0 levels and disease acivity parameters of RA.

콜라겐 유도성 관절염을 발생시키는 과정에서 IL-10을 투여한 본 연구에서는 관절염을 악화시키는 결과를 보였다. 이는 시험관내 실험상 염증억제효과뿐만 아니라 여러 면역세포 촉진 작용도 보인다고 알려진 IL-10이 본 연구에서의 용량으로 콜라겐 항원자극시부터 CIA 모델에 투여하면 관절염의 악화 효과를 보일 수 있음을 보여주었다. 관절염의 중증도나 IL-10투여와 무관하게 콜라겐항체 농도나 비장세포 자극지수가 증가함은 관절염의 악화에 콜라겐항체나 콜라겐 특이 반응세포의 역할외에 다른 기전의 역할임을 알 수 있었다. 본 연구 결과와 상반된 관찰을 보고한 다른 실험의 방법과 본 연구방법의 차이점을 고려할 때 IL-10은 다른 생물학적 제제들과 유사한 속성으로 작용 시기와 용량에 따라서 서로 다른 작용을 보일 가능성을 시사하였다. IL-10이 CIA 발생을 악화시킬 수 있는 기전은 항원제시 세포로서의 B 림프구의 자극, 세포독성 T 림프구의 자극, 대식세포로부터의 산화질소 생성 촉진 등이 가능하나 그 정확한 기전은 향후 더 연구되어야 할 과제라 생각된다. Objective: To evaluate the effect of IL-10 on development of collagen-induced arthritis, on humoral and cellular immunity and on the endogenous production of IL-10 in DBA/1J mice. Methods: DBA/1J mice were immunized with chicken type II collagen in Freund`s complete adjuvant. Murine recombinant IL-10 was given intraperitoneally twice a week from the day of second immunization (week 3) in doses of 0.002ug, 0.02ug and 0.2ug for 3 different groups, respectively. Dexamethasone was injected in one group to suppress the arthritis development and this group was used as negative control group. Levels of anti-collagen antibodies, serum IL-10 and stimulation indices of splenic monocytes to collagen were measured at the end of study. Results: The 0.02ug IL-10 and 0.2ug IL-10 treated groups developed earlier and more severe arthritis (week 6 and 8) compared to that of the control group while the 0.002ug IL-10 group has shown similar course to the control group in terms of incidence and severity of arthritis, At week 10, all groups with or without IL-10 injections developed arthritis with similar degree of severity while dexamethasone group showed far less incidence and severity of arthritis. The serum levels of anti-collagen antibody, IL-10 and spleen monocyte stimulation indices to collagen antigen showed no difference among control group, IL-10 injected groups and dexamethasone injected group. Conclusion: This study shows IL-10 could worsen the arthritis in CIA with the dosage used in this study without significant influence on the level of anti-collagen antibodies or stimulation indices of spenic monocyte to collagen.

Objective: To investigate the distribution of serum uric acid levels among 20000 Korean people who visited health screening center and relationships between serum uric acid and a number of biological variables. Methods: By descriptive analysis on obesity index, blood pressures and various chemical measurements. Serum uric acid levels were measured by uricase method. Stepwise regression analysis of serum uric acid levels on various host variables selected on the basis of univariate analysis was perfomed. Logistic regression analysis was performed for the odds ratios for hyperuricemia. Results: The mean serum uric acid level and prevalence of hyperuricemia were 5.9±1.3 mg/dl, 16.6% respectively in men and 4.2±1.0mg/dl, 1.69% in women. Serum creatinine concentration was by far the most important correlate with serum uric acid level. Obesity index, serum calcium, triglycerid were also significantly associated with serum uric acid in both sexes. Contributing factors for hyperuricema were calcium, serum GPT and obesity index in both sexes, and serum triglyceride level, age, hypertension in men only. Conclusions: The mean serum uric acid level in men is higher than in women throughout all ages and the uric acid level arised after 5th decade in women. There are differences in contributing factors for serum uric acid level between sexes as well as in risk factor for hyperuricemia.
