본 연구의 목적은 김용승(1996)이 개발한 심리기술 강화 훈련 프로그램(시합불안 제어용)의 단축형을 스포츠 현장의 프로 골프 선수 남녀 2명에게 적용하고 그의 시합불안 제어 효과를 조사하고자 하는 것으로 2개의 1인 대상 연구 형태로 이루어졌다. 개입 프로그램은 합리적 정서적 치료(RET) 및 합리적 인지 재구성(CRR)을 기반으로 하여 개발한 것으로, 현장에서 심리학적 전문 지식이 없어도 적용이 가능하도록 127개의 진술항목이 개발되어 포함되어 있다. 대상은 각각 KPGA와 KLPGA 정회원이고 평소 시합불안 제어가 필요함을 표현하던 선수이었다. 연구 개입은 각각 4회기에 걸쳐 이루어졌고, 개입 전후에 SCAT 검사를 하여 특성 시합불안의 변화를 조사하였다. 개입 후에는 보충 면접(back-up interview)를 통해 1인 대상 연구의 단점을 보완하고자 하였다. 남자 선수 C는 연구 개입 전후의 SCAT 점수가 같은 11점으로 변화가 나타나지 않았다. 본인의 개입 전 점수가 이미 최저점(10점)에 근접하여 연구 대상 선택이 적절하지 못하였다. 그러나 개입 후 보충 면접에서 C는 연구 개입이 시합불안 제어에 실제 큰 도움을 주었다고 진술하였다. 여자 선수 M의 SCAT 점수는 연구 개입을 전후하여 18점에서 17점으로 감소하였다. 점수로는 1점 차이나 이것이 특성 불안의 변화임을 감안하면 상당한 의미가 있는 결과이었다. 미국 대조군의 Norm Data를 원용하면 Z-score로 0.23의 변화, 백분위에서 9%의 변화에 해당된다. 개입 후 면접에서 M 본인도 이 프로그램에 의한 상당한 불안제어 효과에 대해 진술하였다. 이 프로그램에 의한 훈련개입 효과가 기대되며, 이어지는 효과 검증 연구가 필요하다고 사료된다. The purpose of the present study was to examine the anxiety reducing effects of the cognitive restructuring program (simple version) developed by Kim Yong-Seung(1996). Its intervention effects on two pro-golfers`(m/f) competitive trait anxiety(pre-to-post SCAT score) were investigated. It was two independent one-person studies. To enhance internal validity, back-up interviews were performed after the last interventions. After 4 sessions of the cognitive restructuring intervention, the study results were; (1) the reduction of SCAT scores for male golfer C was not found. C`s pretest score was 11, only 1 point above the minimum score. The inappropriate selection of the subject was recognized. In the back-up interview, however, C stated that the intervention had been very helpful for his controlling anxiety in the actual competitions. (2) The SCAT score change for female golfer M was from 18 to 17. It was only 1 point reduction, but was meaningful, considering its being a trait anxiety change. According to the norm data, the change corresponds to 0.23 reduction in Z-score and 9% change in percentile. In the back-up interview, M also stated the strong effectiveness of the intervention program in the competitions. The need of well-designed future studies with a larger sample size and a stronger intervention program are recommended.

1. Differences in reactions of leaf and neck of rice plants to rice blast among four rice cultivars were observed in a paddy field. Cultivars Jinheung and Milyang 23 showed susceptible and resistant reactions, respectively, on both leaf and neck. Cultivar Norin 6 was susceptible to leaf blast and became intermediately resistant to neck blast whereas cultivar Ginga showed resistant and intermediately resistant reactions on leaf and neck, respectively. 2. Three different heading dates at 5 to 8 day intervals were induced by transplanting seedlings of four cultivars from seedling beds to a paddy field three times at 9 to 10 day intervals. When blast severity was compared within cultivars, leaf blast severity increased as heading dates became late. However, neck blast severity was greater in plots with early heading dates than those with late heading dates. 3. Spore germination of two isolates of Pyricularia oryzae in tissue extracts from leaf and neck of four rice cultivars indicated significant interactions between cultivars and isolates. However, spore germinations in leaf and neck extracts were not significantly different. Mean degree of hyphal growth of four P. oryzae isolates on the sheath adaxial epidermis indicated significant interactions between cultivars and isolates. 4. Some anatomical characteristics of leaf and neck of four cultivars did not have apparent relationship with the reactions of four cultivars to rice blast in the paddy field. Also, the amounts of the total nitrogen, sugar, P₂O??, and SiO in flag leaf and neck were not significantly different among four cultivars and did not seem to affect changes in reactions of cultivars Norin 6 and Ginga to leaf and neck blasts observed in the paddy field.

Scrub typhus is a potentially fatal infectious disease caused by the organism Orientia tsutsugamushi. Clinical manifestations are fever, skin rash, eschar and varying degree of respiratory distress. The pleural effusion in scrub typhus is rare and secondary to the destruction of vascular endothelium. Because the respiratory symptoms are generally mild and the pleural effusion in scmb typhus is rare than in interstitial pneumonia, there are few comments about the characteristics of scmb typhus with pleural effusion. So we made the comparative study of scmb typhus patients between with pleural effusion and without pleural effusion. 연구배경 치명적일 수 있는 감염질환 중 하나인 쯔쯔가무시중(Scrub typhus)에서 드문 흉막삼출을 동반한 환자에 대한 고찰은 다른 문헌에서도 자주 언급되지 않았다. 따라서 본 저자들은 흉막삼출이 있는 경우와 없는 경우에 따른 쯔쯔가무시중 환자들을 비교하고자 하였다. 방법 2003년에서 2006년까지 조선대학교 병원 내과에 입원중인 환자 중 쯔쯔가무시중 진단을 받은 총 109명의 환자를 대상으로 하여 흉부 X선 검사 및 혈청학적 검사(CPK, LDH, ESR, CRP, AST, ALT, ADA), 혈액학적 검사(WBC, PLT) 및 백분율 검사등을 실시하였다. 결과 흉막삼출이 있는 환자들의 경우 흉막 삼출이 없는 환자들에 비해 ESR 수치가 통계학적으로 의의있게 높았다(p-vaule < 0.05). 결론 흉막삼출 유무에 따른 쯔쯔가무시중 환자간의 비교에 있어 ESR 수치가 통계학적인 의의를 가졌다.

The purpose of this study was to investigate the effects of exercise training on Serotonin and Dopamine level in schizophrenic patients. The subjects consisted of 12 schizophrenic patients and 6 normal individuals between 20 and 30 years old, were invided into three groups: 1) Experimental group(N=6), 2) Control group(N=6),3) Compared group(N=6). Subjects participated in aerobic and strength exercise program for 8 weeks according to the exercise prescriptions. They performed exercise for 1 hours per day, three times a week at 50-60% of HRpeak. The changes of serotonin, dopamine level in the subjetcs before and after the treadmill exercise program have been measured. The results were been compared to serotonin, dopamine between all groups. The results were as follows; 1. Effects of exercise training on serotonin level in three groups were not changed significantly and changed significantly within those groups after acute exercise and resting. Interaction effect within group and treatment time was not significantly changed. 2. Effects of exercise training on dopamine level in three groups were not changed significantly and changed significantly within those groups after acute exercise and resting. Interaction effect within group and treatment time was not significantly changed.

In order to study the temporal variations of nutrients and chlorophyll-a in the Bottol Bada, three field observations were carried out on 20, 23 and 26 July, 2004. The low N:P values exhibit nitrogen deficiency during the periods of observation. This result is not representative of typical summer environment in the southern coast of Korea. The possible mechanisms are as follows: 1) The freshwater inflow was not sufficient for the supply of nitrogen because the total precipitation was 11.9 mm in July, 2004. This amount is no more than 5% in normal precipitation in July. 2) There was an inflow of oceanic water under the subsurface into the Bottol Bada. Even though the oceanic water comprises more nutrients, it produces the stratification between the surface and the subsurface water and seems to prevent the supply of nutrinets to the surface layer. 3) The high chlorophyll-a concentration of 1.2 ㎍/L was shown near the narrow channel between Gae-do and Geumo-do. This seems to be resulted from the inflow of water from Gamak Bay.

Background : Gastric cancer is the most common malignant tumor in Korea. surgical operation is one of the major treatment modalities for gastric cancer patients. Therefore, gastrectomy is one of the most common procedures in General Surgery. There were variation in length of hospital stay and medical treatment for gastrectomy between three surgeons at Asan Medical Center. Clinical pathways have received considerable attention as a tool for recucing the medical practice variation, increasing the efficiency of care process, and improving the quality of care. The aim of this study was to evaluate the effect of a clinical pathway for gastrectomy in gastric cancer patients. Methods : The clinical pathway for gastrectomy was developed and implemented by a multidisciplinary group in Asan Medical Center. A computerized clinical pathway program was developed and revised after a pilot test. A total of 145 patients underwent gastrectomy by three surgeons at Asan Medical Center. We compared the length of hospital stay, patient satisfaction, and unplanned readmission rate between the pre-pathway group(n=67) and the post-pathway group(n=78). We also investigated the degree of satisfaction among the physicians and nurses who were main end-users of the clinical pathway. Results : The clinical pathway was applied to all target patients. The average length of hospital stay was shortened from 12.7days to 10.6days(p<0.01). The degree of patient satisfaction with the care process changed from 90.3% to 89.2% after the implementation of the clinical pathway, but the difference was of satistically significant(p=0.761). Unplanned readmission rate was 2.9% in the pre-pathway group. More than 90% of physicians and nurses answered that the clinical pathway had been a useful tool in their medical practice. Conclusions : The findings of the study demonstrated that implementation of the clinical pathway for gastrectomy produced substantial reduction in the length of hospital stay while improving the quality of patient outcomes. The computerized clinical pathway program can be used as one of the powerful patient management tools for reducing the practice variations and increasing the efficiency of care process in Korea hospital settings.

Objectives : This study is to investigate the hypothesis that schizophrenic patients have difficulty in inferring mental state of others. Methods : Twenty schizophrenic patients and twenty normal subjects were administered to the Cartoon Task required inferring the character's intention in a given context. Results : The schizophrenic patients showed a statistically significant impairment in the Cartoon Task. Both groups chose the card depicting a frequent everyday action significantly more rather than the similar card to the last picture in each story for wrong answers. Conclusion : These preliminary results suggest that schizophrenia is associated with a specific deficit of the cognitive ability referred to as social cognition, and this deficit can be detected not only in the acute phase as found in previous research studies, but also in remission. Also when subjects fail to appreciate what is going on in the minds of other people, they seem to rely on a socially familiar experience.

Background: Pulmonary paragonimiasis is caused by consumption of raw or improperlycooked crustacea infected with the laval stage (metacercaria) of Paragonimus westermani. The most characteristic symptoms were rust-colored sputum and cough. Paragonimiasis causes pleural thickening or effusion in 48% of the patients. Pleuro-pulmonary paragonimiasis can be easily overlooked by physicians who do not suspect this disease in the differential diagnosis. Method: We compared the outcomes of 11 patients with paragonimus empyema managed either through thoracotomy or pig-tail catheter drain. These patients were confirmed by food history, clinical and radiological findings, and laboratory data. Results: The male and female ratio was 1.75 : 1, and mean age was 40.0 ± 13.5 years. AII patients had pulmonary symptoms such as cough or chest pain. Serum-ELISA for paragonimiasis were all positive (mean titer was 0.57). AII patients had pleural effusion in radiological findings( 2 patients had bilateral pleural effusion). All patients received praziquantel (75 ㎎/㎏/day for 3days). Two patients were treated with thoracotomy and nine patients were treated with pig-tail drain. Hospital stay were 14.5 days in thoracotomy group and 5.6 days in pig-tail group respectively, Conclusion: Compared to the conventional thoracotomy grouP, the patients with paragonimus empyema who received pig-tail catheters had a significantly-decreased period of drain in situ, were clinically improved earlier, and were discharged earlier.
