  • 복합소재는 화학적, 역학적인 면에서 여러 장점을 가지고 있다. 피로 저항성과 화학적 저항성이 높을 뿐 아니라, 비강도, 비강성 등이 높아서 높은 감쇠 특성을 보인다. 항만 구조물에 사용되는 파일은 압축 뿐만 아니라 휨을 받기도 하므로 이에 대한 연구가 필요하다. 본 연구는 대구경을 포함하는 콘크리트 충전 유리섬유 복합소재 파일의 압축 거동 혹은 휨-압축 거동을 분석한다. 지름 및 길이가 서로 다른 25개의 실험 파일을 제작하는데, 시편의 복합소재 튜브 내경은 165 mm에서 600 mm에 이르고, 길이는 1,350 mm에서 8,000 mm에 이른다. 수적층 및 필라멘트 와인딩 성형 공법을 모두 사용하여 튜브를 제작하여 적층의 구조가 미치는 차이를 알아보았다. 충전 콘크리트의 강도로는 27 MPa과 40 MPa를 사용하였다. 축방향 및 원주방향의 섬유의 부피비에 변화를 주어 각각의 영향을 분석하였고, 일부 시편에는 나선형 홈을 튜브 안쪽에 성형하여 충전 콘크리트와 튜브 사이의 전단변형을 줄이는데 기여할 수 있는지 분석하였다. 실험결과를 보면, 직포만을 사용하여 수적층 성형 공법으로 파일을 제작하는 것보다 필라멘트 와인딩 성형 공법을 이용하여 제작하는 것이 휨강성을 높이는데 훨씬 유리하다. 나선형 홈을 성형해서 넣더라고 휨강성은 낮은 하중단계에서 부터 지속적으로 감소하는 경향을 보이는 것으로 보아, 충전 콘크리트와 튜브 사이의 전단변형을 완전히 억제하지는 못하는 것으로 판단된다.

  • In the present study, we apply the multiple cue probability learning (MCPL) paradigm to examine consumer learning from feedback in repeated trials. This paradigm is useful in investigating consumer learning, especially learning the relationships between the overall quality and attributes. With this paradigm, we can analyze what people learn from repeated trials by using the lens model, i.e., whether it is knowledge or consistency. In addition to introducing this paradigm, we aim to demonstrate that knowledge people gain from repeated trials with feedback is robust enough to weaken one of the most often examined contextual effects, the asymmetric dominance effect. The experiment consists of learning session and a choice task and stimuli are sport rafting boats with motor engines. During the learning session, the participants are shown an option with three attributes and are asked to evaluate its overall quality and type in a number between 0 and 100. Then an expert's evaluation, a number between 0 and 100, is provided as feedback. This trial is repeated fifteen times with different sets of attributes, which comprises one learning session. Depending on the conditions, the participants do one (low) or three (high) learning sessions or do not go through any learning session (no learning). After learning session, the participants then are provided with either a core or an extended choice set to make a choice to examine if learning from feedback would weaken the asymmetric dominance effect. The experiment uses a between-subjects experimental design (2 × 3; core set vs. extended set; no vs. low vs. high learning). The results show that the participants evaluate the overall qualities more accurately with learning. They learn the true trade-off rule between attributes (increase in knowledge) and become more consistent in their evaluations. Regarding the choice task, there is a significant decrease in the percentage of choosing the target option in the extended sets with learning, which clearly demonstrates that learning decreases the magnitude of the asymmetric dominance effect. However, these results are significant only when no learning condition is compared either to low or high learning condition. There is no significant result between low and high learning conditions, which may be due to fatigue or reflect the characteristics of learning curve. The present study introduces the MCPL paradigm in examining consumer learning and demonstrates that learning from feedback increases both knowledge and consistency and weakens the asymmetric dominance effect. The latter result may suggest that the previous demonstrations of the asymmetric dominance effect are somewhat exaggerated. In a single choice setting, people do not have enough information or experience about the stimuli, which may lead them to depend mostly on the contextual structure among options. In the future, more realistic stimuli and real experts' judgments can be used to increase the external validity of study results. In addition, consumers often learn through repeated choices in real consumer settings. Therefore, what consumers learn from feedback in repeated choices would be an interesting topic to investigate.

  • Background: The conventional deadlift is a popular exercise for enhancing trunk, core, and lower extremity strength. However, its use in sports medicine is constrained by concerns of lumbar injuries, despite evidence supporting its safety and rehabilitative benefits. To optimize muscle activation using resistive bands in variable resistance therapy, we explored their feasibility in the deadlift. Design: Comparative experimental design Methods: Surface electromyography recorded muscle activity in the trunk and lower extremities during lifting, with normalization to the isometric Floor Lift using Maximal Voluntary Contraction. Kinematics were measured using inclinometer sensors to track hip and trunk sagittal plane angles. To prevent fatigue, each subject only used one of the three pairs of bands employed in the study. Results: Our study involved 45 healthy subjects (mean age: 30.4 ± 6.3 years) with similar baseline characteristics, except for years of lifting and strength-to-years-of-lifting ratio. Various resistance band groups exhibited significantly higher muscle activity than conventional deadlifts during different phases. The minimal resistance band group had notably higher muscle activity in the trunk, core, and lower extremity muscles, particularly in the end phase. The moderate resistance band group showed increased muscle activity in the mid-and end-phases. The maximum resistance band group demonstrated greater muscle activity in specific muscles during the early phase and overall higher activity in all trunk and lower extremity muscles in the mid and end phases of the deadlift (p<0.05). Conclusion: Our findings provide valuable insights into muscle activation with various resistance bands during deadlift exercise in clinical and gym settings. There appears to be a dose-response relationship between increased resistance bandwidth, external load, myoelectric activation, and range.

  • Reumatic arthritis is a disease with joint pain being one of the key symptoms. The patient suffers from the pain, stiff sensation and edema due to the inflammation taking Place In one or more joints. Accompanying these problems are fatigue, unusual exhaustion, fever, tachycardia and weakness. Inaddition, joints are often deformed and muscles shrink along with the progress of edema, coupled with depression and psychological instability resulting from the loss of the mobile function and limitations on the daily life. Some patients become fed up with the long and hard flight with the disease and just give up, which aggravates the symptoms. Others come to the hospital only when the conditions have become serious. We need to prevent these and guide the patients in the right direction. Against this backdrop, this study aims to look into the relations between the knowledge on the part of the patients together with their feeling of self-efficacy and the compliance. The results are expected to help the patients improve their life, In addition to providing useful materials for setting up appropriate plan for nursing intervention. The study was conducted by distributing questionnaire to 88 patients selected from the out-patient department of a university hospital in Inchon, from April 6 to 27, 1998. The following tools were used the yardstick of self-efficacy, developed in 1997 by the Society for the Health of Rheumatism Patients, was used for measuring the levels of knowledge and the feeling of self-efficacy. The degree of compliance was measured by the data collected from documents in addition to the results of the analysis of the interviews with the patients. The reliability of the tools was confirmed. In the analysis, the general characteristics were expressed in figures and percentages. The levels of knowledge, feeling of self-efficacy, and compliance were expressed in the average values and standard deviations. The relations among the variables following the general characteristics were analysed by the t-test and one-way ANOVA. The Pearson correction coefficient was used for the analysis of factors. Multiple-loop analysis was used to identify the variables affecting the compliance. The following are the results of this study. 1. Among the 88 patients, 18 were men and the remaining 70 were women, with a ratio 1 : 3.87. Regarding the age groups, 23 were between 50 and 59 years old, with those between 50 and 69 accounting for 51.1% of the total. High school graduates or higher amounted to 58%. Religious patients was 67% or 59 persons. Fifty nine percent were unemployed, and 58.3% (49 persons) had two children or fewer. The period of suffering from rheumatism varied between 2 months and IS years, with 70% less than years. 2. The average figure In relation to the of knowledge was 17.63 points over 30 or 58. 76%, which means a medium level. 3. The average figure of the feeling of self-efficacy was 60.06 points. 4. The level of compliance was 3.26, which was above average. 5. The relation between the feeling of self-efficacy and compliance showed an "r" value of 0.37, which was significant. It means that the higher the feeling, the greater the compliance points. 6. The analysis of the knowledge level revealed that the difference is found only between the college graduates and junior-high graduates or lower. 7. The feeling of self-efficacy varied along with the age and education level. 8. The general characteristics of patients as discussed above did not show significant difference with the compliance. 9. Regarding the elements influencing the compliance, the number of children, period of suffering, income, age, feering of self-efficacy, knowledge, and compliance had 54% of significance. In conclusion, rheumatism victims can lead a better life if they are appropriately educated, based on efficient training program from the early days of the disease ; if they become able to manage themselves thanks to the training ; and if they are helped by a program focusing on the increase of the feeling of self-efficacy aimed at changing patient's behavior.

  • Objectives: This study was designed to develop and evaluate a stage matched exercise intervention program to effectively increase exercise behaviors in urban elders. Methods: The study included three phases: preliminary descriptive data collection, program development, and program evaluation. The data for the preliminary descriptive phase were collected between May and June 2001. The study participants were 89 urban elders who responded a questionnaire that included general characteristics, exercise related experiences, stage, and process of change in exercise behaviors. Data were analyzed using descriptive statistics, $x^2$-test, and content analysis. Development of the program was based on the preliminary data. and a literature review, and was guided by the tran theoretical model. It consisted of strategies to facilitate the process of changes used in each stage. Evaluation of the program was achieved from October to December 2001, using a case study method, in which eight urban female elders participated. Interviews were conducted on a weekly basis in the form of either an individual interview, or group discussion. Each elder subject received education in accordance with the program strategies and education materials. In the case that a subject's stage of change moved into another one, the scores for the process of change were re-measured. The data were analyzed using the content analysis technique. Results: The results were as follows: 1. Elders who participated in the preliminary data collection phase were over 75 years of age, and the majority of them were women. They had a higher educational level, and fewer number of illnesses than the subjects in other studies. Their stage of change was divided into pre-contemplation and maintenance. The social liberation scores were the highest across all stages of change. There was no difference between men and women on scores for processes of change in each stage. 2. The stage matched exercise intervention program that was developed in this study consisted of one counseling type program and three distinguished educational booklet materials. 3. The results of the case studies are as follows: 1) The study participants were 8 women between 75 and 87 years of age. At the first interviews, all of them were in the pre-contemplation stage. All of them reached the action stage before the 7th week. The scores for processes of change that were the focus in each stage increased more than the scores for other processes of change. During the early stages of change, experimental processes increased more than behavioral processes. However. this pattern was reversed during later stages of change. 2) Characteristics of the subjects in each stage were identical as presented at the tran theoretical model. The intervention strategies were effective in the transition occurred in any stage. 3) Barriers for exercise included unwillingness to exercise, fatigue, shortness of breath, and pain. Ways to overcome these barriers were 'learning an alternative exercise method that can be done at home', 'self-promising/ exercise-promising', and 'use of cues to exercise'. 4) The factors that affected the application of the program were consideration of age and personal preference in selecting an exercise pattern, individualized intervention, and use of education materials appropriate to elders. Women over 80 years of age preferred muscle strengthening and stretching exercise, because they can be easily done at home. They also preferred individualized interventions, materials that were easy to read, and education contents appropriate for elders. Conclusion: In conclusion, the stage matched exercise intervention program that considered the characteristics of the elders was effective to facilitate exercise behaviors of the elders.

  • 목적: 자가면역성 간염은 원인 불명의 진행성 염증성 간질환으로 혈중 자가항체의 출현과 고감마글로불린혈증, 그리고 조직학적으로 문맥주위 염증을 특징으로 한다. 소아에서는 산발적인 증례 보고가 있었으나 국내에서는 아직까지 체계적인 연구가 없었다. 이에 저자들은 소아에서 자가면역성 간염의 임상적, 조직학적 소견과 치료 경과 및 예후에 대해 알아보고자 본 연구를 시행하였다. 방법: 1990년부터 2004년까지 서울대학교 어린이병원에서 자가면역성 간염으로 진단되었던 14명의 환자들의 임상적 특징, 혈액 검사 소견 및 간 조직 검사 소견을 분석하였다. 또한 이들 환자들에게 시행된 치료 약제 및 치료에의 반응, 그리고 재발 여부 등 치료 경과를 조사하였다. 결과: 대상 환자 14명의 진단시 연령은 평균 $9{\pm}3$세였다. 여자가 11명으로 전체의 78%를 차지하였고, 6명에서 급성 발병을 보였다. 임상 증상으로는 황달이 11명에서 호소하여 가장 흔하였으며, 이 외에도 피로감, 식욕부진, 진한색 소변, 상복부 불쾌감, 잦은 코피, 오심, 소양감 및 설사가 동반되었다. 신체 검진 소견에서는 간비종대가 흔하게 나타났다. 6명의 환자에서 다른 자가면역성 질환이 동반되었고 1명에서는 일등친 중 그레이브스병의 병력이 있었다. 혈중 자가항체 검사 결과 13명에서 항핵 항체가 양성으로 나왔으며 항핵 항체가 음성으로 나왔던 1명은 항평활근 항체가 양성으로 나와 대상 환자 모두가 제1형 자가면역성 간염에 해당되었다. 7명에서는 항핵 항체와 항평활근 항체가 모두 양성으로 나왔다. 혈청 IgG는 평균 $2971{\pm}2147mg/dL$였고, AST는 평균 $469{\pm}402\;U/L$, 총 빌리루빈은 평균 $4.9{\pm}5.5mg/dL$였다. 간 조직 검사 소견으로는 문맥 주위의 염증(10명), 간세포의 로제트 형성(3명), 소엽의 염증(6명)이 흔하게 나타났고 2명에서는 진단 당시 이미 조직학적으로 간경변이 동반되었다. 대상 환자 14명 중 6명은 UDCA만 사용하며 관찰 중 간수치가 호전되었고 나머지 8명에게는 스테로이드 치료가 시행되었다. 이중 7명이 초기 스테로이드 치료시 관해를 보였으나 스테로이드를 감량하거나 중지시 재발하였다. 스테로이드 재치료가 시행되었고 3명은 스테로이드 감량 중 관해 유지 중이고 2명은 azathioprine으로 관해 유지 중이다. 결론: 자가 면역성 간염은 원인 불명의 소아 만성 간 질환의 원인 중 하나이며, 적절한 치료로 예후가 개선될 수 있는 간질환이다. 그러므로 특히 여아에서 고감마글로블린혈증을 보이거나 다른 자가면역성 질환이 동반될 경우 자가면역성 간염을 의심하여 자가항체 선별 검사를 시행하고 적절한 진단 및 치료를 시행하는 것이 중요하리라고 생각된다.

  • 성인에서 항체 보유율이 급감하는 것에 비례하여 급성 A형 간염 환자는 증가하고 있다. 대구지역에서의 급성 A형 간염의 역학과 임상 양상에 관한 자료를 얻고자 하였다. 1998년 1월부터 2007년 6월까지 영남대학교병원에 급성 간염으로 입원하여 IgM anti-HAV 양성으로 급성 A형 간염이 확진된 55명의 환자들(남/녀 34/21)의 의무기록을 후향적으로 검토하였다. 평균 연령은 $29.7{\pm}10.3$세(범위 17~65세)였고, 20대와 30대에 78.2%가 발생하였다. 만성 B형 간염이 4명 (7.3%)에서 동반되어 있었으나, 모두 비증식상태로 임상경과는 양호하였다. 1998년부터 2002년 사이에 9.1%가 발생한 데 반해 2003년부터 2007년 6월까지 90.1%가 발생하였고, 계절적으로는 3~6월 사이에 31명 (56.1%)으로 가장 많이 발생하였다. 여행력이 있는 7명(12.7%)을 제외하고는 감염원을 추정하기가 힘들었다. 임상증상은 식욕부진과 오심, 구토38예(69.1%), 열/오한 27명(49.1%), 전신근육통 26명(47.3%), 체중감소 26명(47.3%), 피로감 22명(40.0%), 복통이 20예(36.4%), 설사 5명(9.1%), 소양감 3명(5.5%) 등이었다. 54명은 합병증 없이 자연회복되었으나 1명은 전격성 간염이 발생하여 간이식을 받고 회복되었다. 평균 재원일은 $8.6{\pm}3.4$일(범위 3~20일)이었다. 성인에서의 급성 A형 간염은 입원으로 인한 사회, 경제적 비용이 적지 않고 때로는 치명적인 결과를 초래할 수도 있으므로 능동면역을 받지 않은 30대 이전의 젊은 연령에서는 항체의 확인과 함께 능동면역을 고려해야 할 것으로 생각한다.

  • 본 연구는 세월호 참사 이후 안산시의 고잔동과 와동을 중심으로 나타난 대안적 치유의 공간의 지리적 특징에 대해 살펴보는 것을 목표로 한다. 세월호 참사의 내면을 들여다보면 치유 대상의 스펙트럼이 넓게 퍼져 있어 개별 치유의 공간이 지향하고 있는 치유의 목표는 그 주체에 따라 다소 상이하다. 현재 세월호 참사 관련 치유의 공간은 약 7개 내외로 추산되며, 민간에서 주도하는 형태가 주류를 이룬다. 또한 이러한 공간은 가장 많은 희생자가 나온 단원고등학교 주변이되 시선에서 약간 빗겨간 곳에 위치해 있고, 특별한 활동을 하기보다는 깨어진 일상을 다시 원래의 자리로 회복시키기 위한 단순하며, 반복적인 일, 예를 들어, 식사, 뜨개질, 학습 등을 주요 치유의 활동으로 하고 있다. 이러한 배경을 바탕으로 세월호 참사 관련 치유의 공간의 주요한 특징은 다음과 같이 정리할 수 있다. 첫째, 치유의 대상이 개별 치유의 공간을 장소로 점점 받아들이고 있다는 점을 들 수 있다. 세월호 참사 관련 치유의 공간은 제3자에 의해 처음 제안된 경우가 대부분이었지만, 이제는 치유의 주체들이 스스로 끌어가거나, 기억하며, 심지어 앞으로의 방향까지 설계하고 있어 마치 그들만의 전유물처럼 인식되는 경향이 나타나고 있다. 둘째, 앞서 언급한 것처럼 세월호 참사는 직접적인 피해자뿐만 아니라 희생자의 부모, 형제, 친척, 친구, 지역주민 등까지 넓은 범위의 집단에게 트라우마를 지운 사건이었던 만큼 치유의 공간이 지원하는 대상은 폭넓지만, 개별 치유의 공간을 활용하는 대상은 겹치지 않는다. 그렇지만 지역 커뮤니티가 가지고 있는 집단 트라우마를 효율적으로 해결하기 위해 지역 내 네트워크를 조밀하게 유지하고 상시적으로 협력하는 형태를 취하고 있다. 셋째, 참사와 같은 트라우마 극복에 있어 사건의 지속적인 기억은 매우 중요한 부분으로 지적되는데, 세월호 참사의 경우에는 지역주민들의 피로감 혹은 갈등, 노후화된 안산시를 떠나는 이들, 시간이 지나감에 따른 퇴색되는 분위기 등이 기억의 유지에 위험 요소로 작용되고 있다. 이를 위해 치유의 공간을 중심으로 지역공동체 회복, 다양한 이벤트 기획 등을 시도하고 있으며, 안산시 외의 다른 단체와도 유기적으로 연결해 세월호 참사의 기억이 오래 지속될 수 있도록 하고 있다.
