An inflammatory difference between the gastric antrum, body and fundus was studied in 39 H.pylroi positive duodenal ulcer and 29 H. pylori chronic gastritis patients. Also we studied correlation of H. pylori colony count and inflammatory severity. Patients with newly diagnosed duodenal ulcer and chronic gastritis were endoscoped and two biopsy secimens each taken from the antrum, body and fundus. Although intestinal metaplasia in antrum and inflammatory activity in fundus were more severe in chronic gastritis patients. another inflammatory difference was equally likely to be found between two groups. There was no definite histological inflammatory difference between duodenal ulcer and chronic gastritis patients. A positive correlation was found between the number of H. pylori and the severity of inflammation.

The purpose of this study was to examine the influence of individualism-collectivism(horizontal individualism, horizontal collectivism, vertical individualism, vertical collectivism) and causal attribution style on college students’ attitudes toward seeking professional help in Korea. Three hundred and eleven college students(197 men and 114 women) participated in this research. Each participant responded to three instruments; The Attitude Toward Seeking Professional Help Scale, The Individualism-Collectivism Scale, Attributional Style Questionnaire. To analyze the data, correlation analysis and stepwise regression analysis were conducted. The result of correlation analysis indicated that attribution style, horizontal individualism and horizontal collectivism were positively correlated to attitudes toward seeking professional help, and vertical individualism was negatively correlated to attitudes toward seeking professional help. The result of stepwise regression analysis indicated that the horizontal individualism, horizontal collectivism and vertical individualism had significant influence on attitudes toward seeking professional help. Causal attribution style didn't have significant influence on attitudes toward seeking professional help.

본 연구는 IMF에 관련된 경제적 스트레스가 정신 건강에 미치는 영향과 그 과정을 밝히기 위해 설계되었다. 스트레스 과정에 관여하는 요인으로 사회적 지지와 문제 해결 양식, 그리고 무망감을 도입했으며, 이들에 의해 스트레스의 영향이 매개되는지를 검증하였다. 경제적 스트레스의 수준에 따라 표집된 221명의 일반인들을 대상으로 우울, 불안, 신체화, 적대감, 사회적 지지, 그리고 문제 해결 양식 등을 측정하였다. 가정한 대로 실직으로 대표되는 경제적 스트레스는 정신 건강에 부정적 영향을 미치는 것으로 나타났다. 그 구체적인 양상을 살펴보면 다음과 같다. 먼저, 사회적 지지는, 높은 스트레스 조건에서 증상의 발현을 억제하는 완충 효과가 있음이 입증되었다. 두번째로, 남성이 여성에 비해 경제적 스트레스의 부정적 영향에 더 취약한 것으로 나타났다. 세번째, 경제적 스트레스는 문제 해결 양식의 다양한 구성요소중 문제 해결에 대한 무기력감에만 영향을 미치는 것으로 나타났다. 네번째, 무망감은 경제적 스트레스와 정신 건강간의 관계를 매개하는 변인임이 인과모형 검증을 통해 확인되었다. 끝으로, 이러한 결과가 스트레스 개입 프로그램 개발을 위한 이론적 기초를 제공한다는 의의가 있음을 논의 했고, 본 연구의 몇 가지 한계점을 지적하였다. This study was designed to investigate the influence of the so-called IMF-related economic stress upon the mental health and to analyze the process of the influence. As the possible variables moderating the stress process, social resource, problem solving style, and hopelessness were included. 221 male and female subjects were recruited according to the intensity of economic stress and classified into four groups(employees of solid companies, employees of the companies at risk, short-term unemployed and long-term unemployed). Relevant measures including economic stress scale, selected SCL-90R subscales(somatization, depression, hostility, anxiety), social support scale, problem-solving scale, and job hopelessness scale were administered. As assumed, it was proved that economic stress had adverse effects on the mental health. In addition to this basic causal relationship, moderating effects of several variables were found as follows: First, social support had the buffering effect upon the economic stress. That is, strong social support played the role suppressing the development of psychiatric symptoms under high stress. Second, men were more vulnerable to the adverse effects of economic stresses than women. Third, economic stresses had influence on the helplessness concerning the problem solving. However other problem solving strategies such as creative style, approach style, avoidance style, etc were proven to have no relationship with the economic stress. Fourth, in the analysis of unemployed group, it was found that hopelessness mediates the relationship between economic stress and mental health. In conclusion, the clinical implications of such findings in economic stress process were discussed and several limitations and the suggestions for future researches were also addressed.

This Study aims at looking into the use of oriental medical services in treating hypertension. The first objective to be explored through this study is the morbidity caused by the disease, classifying them by age, gender, and occupation. The second is to determine the regular use of anti-hypertensive medicine and their efficacy in controlling blood-pressure. The third is to investigate the use-rate and satisfaction of oriental medical service. 838 households across the country, were asked to answer questionnaires for the period of time from Apr. to Jun. 2005. The conclusion from the survey can be summarized as following. The age of which the first medical diagnosis of hypertension were made showed lower in males, those with higher education and income. The study showed females were more active in blood-pressure control, with their frequent monitoring of blood-pressure for the past year. With age, people in under 50 age group proved to be less active. The management of high blood pressure was more effective in group with regular dosage compared to group with irregular use of anti-hypertensive medication, but their difference was minimal. Also, group with no medication showed signs of blood-pressure control. The use of oriental medical service for the past year, were more frequent in groups with lower education, either low or high income, old age, females and occupations in agriculture, forestry and fishing industry. Results were similar in both general population and high blood-pressure patient group. Females, people over 51 years old and with lower education showed more intentions in utilizing oriental medical services in the future. Results were similar in both general population and high blood-pressure patient group. It is necessary to offer a more accurate information on oriental medical treatments. Also, a systematic reform to reduce the patient's share of the treatment cost, as well as, heightening public awareness on the infirmity of present blood-pressure management system is crucial.

목적 : 조혈모세포이식 환자에서 호중구 감소 기간 동안 이트라코나졸 액(ITZS)과 플루코나졸 시럽(FCZS)의 진균 감염에 대한 예방 효과를 전향적으로 비교해 보고자 하였다. 재료 및 방법 : 2001년 8월부터 2002년 6월까지 가톨릭 조혈모세포이식센터에 입원하여 동종 조혈모세포이식을 받은 만 18세 이상의 환자들을 각각 ITZS와 FCZS군으로 무작위 배정하여 침습성 진균 감염 발생과 약제 관련 부작용을 전향적으로 조사하였다. 결과 : ITZS군에 40명, FCZS군에 38명이 배정되었고, FCZS군 환자의 평균 나이가 더 많았다. 시험 약제 평균투여기간은 ITZS군 16.4일, FCZS군 21.9일로 ITZS군이 더 짧았다. 이는 ITZS군에서 소화기 부작용으로 인한 약제 중단이 더 많았기 때문으로 보인다. 시험 약제 투여 후 총 빌리루빈 수치의 유의한 증가가 관찰되었으나, 약제 관련 부작용은 모든 환자에서 가역적이었다. 호중구감소 기간동안 표재성 진균 감염은 두 군에서 모두 발생하지 않았고, 침습성 진균 감염은 ITZS군 5명(12.5%), FCZS군 8명(21.1%)으로 FCZS군에서 많았으나, 통계학적으로 유의하지 않았고, 사망률에도 유의한 차이는 없었다. 결론 : 침습성 진균 감염에 대한 이트라코나졸 액과플루코라졸 시럽의 예방 효과에 유의한 차이는 없었으나, 앞으로 더 많은 환자를 대상으로 잘 짝지어진 대조군 연구가 필요할 것으로 보인다. 부작용 중 간독성과 관련하여 이식시 투여되는 여러 약제들과의 상호작용에 대한 연구도 필요할 것이다. Background : Though fluconazole is widely used for antifungal prophylaxis, it is ineffective against mould infections including Aspergillus species. Itraconazole has a broader spectrum than fluconazole but the capsule form shows erratic bioavailability in neutropenic patients. In this study, we compared itraconazole oral solution (ITZS) with fluconazole syrup (FCZS) for the prevention of invasive fungal infection (IFI) in allogeneic hematopoietic stem cell transplant recipients. Materials and Methods : Adults receiving allogeneic hematopoietic stem cell transplantation (HSCT) from september 2001 to June 2002, were randomly allocated to either the ITZS group or the FCZS group. We prospectively evaluated the safety and efficacy of each drug. Results : Out of 78 patients (40 patients in the ITZS group and 38 patients in the FCZS group) who were eligible for this study, 37 patients completed the course of prophylaxis without any evidence of IFI. The mean duration of prophylaxis was 16.4 days for the ITZS group and 21.9 days for the FCZS group (P<0.006). Drug-related adverse events occurred in 28 patients (70.0%) and 19 patients (50.0%) in the ITZS group and the FCZS group, respectively. Common adverse events of ITZS were nausea, vomiting, and diarrhea. Drug-related reversible hepatotoxicity occurred in 4 patients in the ITZS group. There was a significant elevation of total bilirubin level in the ITZS group. The incidence of suspected IFI occurred in 5 patients (12.5%) who received ITZS, compared with 8 (21.1%) who received FCZS (P=0.372). There were no proven IFIs or superficial (oral/vaginal) fungal infections in both groups. Overall mortality was not different between the two groups (2.5% in the ITZS group versus 5.3% in the FCZS group, P=0.610). Conclusion : ITZS and FCZS showed similar protection against IFI during pre-engraftment period. Poor tolerability due to gastrointestinal troubles of ITZS might limit its success as prophylactic therapy. Well matched controlled study with large number of patients will be required in the future.

This is the study on net effect of the wind to protect some kinds of crop from harm. Nets used in the research are an indigo-net, a wirenetting, and a green net. Its permeability in each is 20%, 23%, and 33% respectively. Experiment results are as follows: Crops frequently seen in our surroundings with thinner stems, more leaves, and larger nuts are more influenced by the wind. And among the three kinds of nets used, the effect of the wind is the greatest in the indigo net. Of many factors which reduce the velocity of the wind, the permeability is the most important one. But quality and standard of nets also influence it.

In manufacturing process, the. free-formed surface machining using a ball end mill of CNC machining center is important and the geometric accuracy of a 3D workpiece is effected by the cutting characteristics. Machining error is defined the normal distance between designed surface and actual tool path with tool deflection. This is inevitably caused by the tool deflection, tool wear, thermal effect and machine tool errors and so forth. In this study, the geometric accuracies such as roundness in semi-cylinder, free-formed profile and surface roughness were measured using a Coordinate Measurement Machine(CMM) and a contact type surface roughness measuring device. The results will be useful as a guidance for cutting condition to improve the geometrical accuracy of free-formed surface in ball end milling.

목 적: 쇄골 간부 골절 불유합에 대하여 관혈적 정복, 재건 금속판 고정 및 골 이식을 시행하고 술후 조기 관절 운동을 허용한 저자들의 경험을 보고하는 것이다. 대상 및 방법: 1997년 1월부터 2001년 12월까지 수술적 치료를 시행한 쇄골 간부 골절 불유합 16예를 대상으로 하였다. 위축성 불유합이 10예, 비후성 불유합이 6예였으며, 수상 후 불유합에 대한 수술까지의 기간은 평균 6.5개월이었다. 수술적 치료로 불유합 부위를 노출시켜 섬유조직을 제거하고 골수강을 천공하였으며, 골편을 정복하고 재건 금속판으로 고정하였으며, 자가 골 이식을 하였다. 수술 후 관절 운동은 1주일 이내에 시작하였다. 결 과: 평균 추시 기간은 22.0개월이었으며, 전 예에서 평균 10.0주에 골유합을 얻었다. 최종 추시 시의 견관절 운동범위는 전 예에서 정상으로 회복되었으며, 나이가 50게 이상인 6예 중 3예에서 동측 견관절에 간헐적인 동통을 호소하였다. 술후 감염, 재검 금속판의 파손, 고정상실, 불유합, 재골절 등의 합병증은 발생치 않았다. 결 론: 쇄골 간부 골절 불유합에 대한 관혈적 정복, 재건 금속판 고정 및 골 이식은 안정성 고정으로 조기 재활이 가능하고 견고한 골유합을 얻을 수 있어 안전하고 확실한 치료방법으로 사료된다. Purpose: The purpose of this study is to present out experience with open reduction, 3.5-㎜ reconstruction plate fixation, bone-grafting, and postoperative early mobilization for nonunions of midshaft clavicular fratures. Materials and Methods: Sixteen patients were treated operatively for nonunions of the midshaft of the clavicle from 1997 to 2001. Ten nonunions were atrophic and six were hypertrophic. Nonunion had been present for an average of 6.5 months. The operative technique included removing the fibrous tissue from the nonunion site and opening the medullary canal, reduction of the fracture and fixation with a 3.5-㎜ reconstruction plate, and bone-grafting. Postoperative mobilization started within one week. Results: The average duration of follow-up was 22.0 months. All fracture were united in an average of 10.0 weeks. All patients had full range of motion of the ipsilateral shoulder, but 3 our of 6 patients who were more than 50 years old complained occasional pain in the ipsilateral shoulder at the final follow-up examination. There were no major complications of postoperative infection, metal failure of the plate, loss of fixation, nonunion, and refracture after removal of the implant. Conclusion: The technique of open reduction, reconstruction plate fixation, and bone-grafting is a safe and reliable method to allow early rehabilitation by stable fixation and to predict a high rate of union for nonunions of midshaft clavicular fractures.
