The purpose of this study was to investigate the effects of the complex exercise program on inflammation markers response in health care with the elderly men. The subjects consisted 55 elderly men, who was aged 68~75 years were checked by a blood test, body composition and exercise stress testing. In measurement index, blood test were measured of WBC, albumin, RF, CRP, and fibrinogen. We enrolled 30 exercise group into the participated week resistance exercise with aerobic exercise program. Statistical analysis was performed using analysis of paired t-test. Results of this study were as follows; In the WBC, exercise group were showed significantly effects of physical activity program participation, but Control group were no significantly. In th CRP and RF, CRP were showed significantly effects of physical activity program participation in the exercise group, and RF were showed no significantly effects of physical activity program participation in the each groups, In the Fibrinogen, exercise group were showed significantly effects of physical activity program participation, but control group were no significantly. These data suggest that the long-term physical activity program is an effective to improve CVD and inflammation markers response, Conclusionally, elderly men will no longer be a rare event, and providers have to prepare to treat such patients on a regular basis.

Male, IcR mice weighing 20 to 25 gm were infected experimentally by esophageal intubation of 300 Trichinella spiralis infective muscle larvae prepared by acid-pepsin digestion of infected mice. Delayed type hypersensitivity and hemagglutinin antibody reactions to unrelated antigen, sheep red blood cell (SRBC) were measured at 37 and 83 days after infection, employing footpad and ear swelling reactions and microtitration technique. All mice were sensitized i.v. with SRBC. It was found that DTH and hemagglutinin responses to SRBC were depressed in infected mice when observed at 37 and 83 days postinfection, and degree of immunosuppression was more profound in mice observed at 83 days than in those at 37 days. The secondary cell-mediated immune response of DTH to SRBC were suppressed in Trichinella - infected mice, indicating the development of immunological memory cell is affected. In addition, immunodepression to SRBC in mice infected with T. spiralis was eliminated by pretreating infected mice by subcutaneous injection of cyclosphosphamide(100㎎/㎏) 2 days prior to infection. These results suggest that the immuno suppression in trichinellosis can be due to suppressor T cells.

The aim of this study was to examine differences in the level of satisfaction with medical care at a public health center between patients receiving free-care compared to those paying out-of-pocket. SERVQUAL(Comprehensive Service Quality Measurement Scale), a pyschometrically valid measure for evaluating hospital service quality, was used to assess patint satisfaction. The study sample consisted of 279 patients who received medical care at a public health center. The interview was conducted between April 23 and May 7. 1998. The results was as follow: 1. There were more elderly people among free-care patients than out-of-pocket patients. Education and income levels were lower amongs those -receiving free-care. There 'were however, no differences in the distribution of gender and religion between the two groups. Patients receiving free-care tended to visit the public health center more frequently compared to those self-paying patients. 2. Overall, free-care patients showed higher satisfaction level than that of self-paying patients, except for the dimension on sympathy and shape.

Today, it has been taking a serious view to make comfortable circumstances that are free from pollution, traffic problems, energy shortage, etc. Therefore, when we plan to improve the road condition in city, we should give priority to building familiar community road. Taking account of this, in the study I have studied the case and policies of foreign countries to community road. The results of this study can summarized as follows. 1 It should be accepted to equip large humps or round shaped humps (length:3.7m, height:l0.cm) that ate generally used in Austria. There is no doubt that traffic signs should be equipped before these humps. 2 Each zone of daily life should be setted up by range of about 1km2 and it should be given various traffic regulations or safety facilities for pedestrians, bicycles (especially, children or the old.l) 3 As living environment is getting worse by inflowing of passing cars, it is important to protect pedestrians, bicycles from cars. Generally, the policy to prohibit large cass(like trucks)into living aces has been taken. In addition to this, from now all the cars(like trucks) into living area has should be excluded from the area, except special cases. 4 The policy that pedestrians should be prior to cars must be enforced in Taegu city, and community road for both pedestrians and cars should be designed. 5 When plan to organize the network of pedestrian lane or bicycle road, we should collect public opinion and policies of executive organizations. Especially, in the case of giving great influence on community transportation as redevelopment of around railroad station, the schemes should be included how to connect pedestrian with car or public transit. Doing all this, the planner should consider the synthetic transportation planning for the small district in urban area.

Jae‑Young Park,Kwangsuk Park,Bosung Seo,Julien O. Fadonougbo,Tae‑Wook Na,Ki Beom Park,Hyeon‑Tae Im,Nong‑Moon Hwang,Hyung‑Ki Park 대한금속·재료학회 2022 METALS AND MATERIALS International Vol.28 No.7

This study examines the insulation coating technology of Fe–Si–Cr powder via selective oxidation annealing, which oxidizeselements selectively by controlling the oxidation potential. The study calculated the oxidation driving force of Fe, Si, andCr, and conducted a thermodynamic analysis of oxidation and reduction conditions according to temperature and oxidationpotential. Based on the results, a selective oxidation annealing was performed in an atmosphere in which Fe is reduced andonly Si and Cr are selectively oxidized. The oxidation potential was controlled through the partial pressure ratio of hydrogenand water vapor. The XPS analysis results confirmed that a Si and Cr complex oxide layer formed on the powder surfaceafter the selective oxidation annealing. Afterward, withstanding voltages were analyzed to evaluate the insulation property. Then, the withstanding voltage of the powder applying the selective oxidation annealing increased significantly comparedto that of the initial powder. Further analysis showed that the powder annealed in an air atmosphere had a significantly lowersaturation magnetic flux density than the initial powder, while the powder applying the selective oxidation annealing hadonly a slightly reduced saturation magnetic flux density.

purpose: This study was conducted to describe qualitatively the entities of nurse's experiences in general hospitals and to suggest basic data guiding research on developing Standards of clinical nursing practice in Korea. Method: Fourteen nurses working at general hospitals with over 300 beds in Seoul were interviewed in-depth until saturation using tape-recorders and transcription. Result: The central theme of clinical nursing practice experienced by subjects was "being with clients" that means accepting client's personal character, solving client's needs and providing client-centered nursing. A also "being with clients" was felt to be the responsibility of nurses which was learned from their nursing schools. The nursing strategies performed in order to be with patients were proving skillful nursing techniques, accepting, educating, emotional support, advocating, and self-reflecting, the subjects experienced somewhat problematic affects such as difficulties in interpersonal relationship, work overload, negative image of nursing, deficit of self-confidence for nursing actions, poor working conditions, and unfair treatment. Nurses at the hospital practiced with pride when they felt that they were accepted by clients. Conclusion: Further research is needed to analysis problems in clinical practice and the comparison of nurses' experiences of clinical practice, with nurses' experiences in various settings.

As a nursing practice involves nurses' actions in a specific context of health care, this study has focused on exploring the espoused theories in nursing practice within the action science perspectives, Espoused theories are the belief, principles, and rationale expressed by the practitioner as guiding her/his actions in a situation of practice. The data were analysed qualitatively and 25 elements of espoused theories of nursing action were identified and clustered into 6 categories. The 25 elements of espoused theories are as follows: The clinical nurse worked in wholistic and individual nursing, focussed on the patient's needed, comfort and supportive nursing (5 theories of nursing goal) ; excellent skills, knowledge based, assessment and data collection, explaining, educating or a scientific basis(6 theories of nursing intervention): advocacy, value oriented, treatment, account- ability and commitment(4 theories of nursing ethics) ; human respect. partnership, trust(3 theories of patient-nurse relationship) : knowledgable, accumulated clinical experiences and personally lived experiences. positive perspectives(4 theories of nurse), role of intervention. rewarding peer relationship(3 theories of situations) The above mentioned espoused theories are similar to that of nursing textbooks which students learned through basic nursing education and almost the same as the Acts ofa Nurse in Korean. However, we are doubtful whether nurses actually do as they think. Therefore. it is recommended to review the theories-in-use in order to and any discrepancies between the espoused theories and the reality of nursing actions

This study was conducted to analyze the morphological characteristics and genetic relationships among 24 species of Gerbera. Most of flower colors were pink. The numerical order of flower color was pink, orange, red, double-colored, and milk-white. Majority of flower types were single or semidouble flowers. A few species were double flowers. Flower diameters were from 7cm to 12cm, showed significant differences compared to other characteristics. Flower stalks were ranged from 55cm to 65cm. Only one species was the shortest as 55cm. The others were similar size as about 65cm. Main annual production yields were between 190 and 400 blossoms. Fifty seven reproducible polymorphic bands from eighty primers were used for analyses of genetic similarity. The genetic similarity of 24 collected Gerberas was largely classified into five groups. The average similarity coefficient was 0.72 ranged from 0.50 to 0.90. The highest similarity coefficient was shown between 'Sardana' with red/white flower color and double flower type, and 'Tamara' with orange flower color and double flower type as 0.90.

Background : About 30% of patients in the hospital are under nourishment. A large portion of people are undernourished when they are admitted to the hospital and in the majority of these, undernutrition develops further while in hospital. Patient-Generated subjective global assessment(PG-SGA), a method of nutritional assessment based on clinical judgment, has been widely used to assess the nutritional status of adults for both clinical and research purposes. Modified PG-SGA can be used as a nutrition screening tool, and a comprehensive nutrition assessment is desirable for those who are malnourished. The purpose of this study is to develop a simple, reliable and valid nutrition screening program(NSP). Methods : We applied the nutrition screening program(NSP) to adult inpatients who are at risk of malnutrition using the Modified Patient-Generated subjective global assessment(PG-SGA) and objective assessment(electrical medical record data). Results : Therefore simple and beneficial NSP is developed for patients with severe malnutrition. Using NSP. nutritional information of the severe malnutrition patient should be shared with the physicians and they should be taken care of by clinical dietitians to improve their nutritional status. Conclusion : The Modified PG-SGA and nutrition screening tool are simple, reliable and valid nutrition screening program(NSP).

Asbestos industry has been in operation over 60 years in Korea. However, the prevalence of asbestosis has not been yet reported. With rapid turn-over of workers, previous cross-sectional studies of current workers on the job could not find cases with exposures long enough for the development of asbestosis. This study was done to evaluate asbestosis prevalence of those worksites with operation history of more than 20 years. In total, 139 workers from 5 worksites were examined. Asbestos industries covered in the study include 2 asbestos textile, 1 brake lining, and 2 ship repairing worksites. Chest x-ray was taken from all workers and read by two experts familiar with pneumoconiosis classification according to 1980 ILO guidelines. Those with findings compatible with asbestosis were further ckecked with high resolution computerized tomography (HRCT). Pulmonary function tests were done according to ATS guidelines, and occupational and previous medical history was taken through a standardized interview. Air-borne asbestos was measured according to NIOSH method 7400. The air-borne asbestos concentrations ranged from 0.2-1.3 f/cc for asbestos textile, from 0.7-1.0 f/cc for brake lining, and from 6.3-7.8 f/cc during asbestos removal at ship repairing worksite. Of the 139 workers 25 had abnormal chest radiographic findings, and 10 of them had findings compatible with pneumoconiosis. When work history and current asbestos measurements were accounted, 9 workers who had more than 10 years of asbestos exposure history showed chest radiographic findings of pneumoconiosis with Finally, 4 workers showed finding of pulmonary fibrosis and/or pleural thickening at HRCT, and 2 of them had restrictive lung function changes. The study results showed that, among 139 subjects, there were 4(3%) definite asbestosis cases confirmed with HRCT. The prevalence of probable asbestosis was 7% for 10-14 years of exposure, 13% for 15-19 years of exposure, and 23% for 20 or more years of exposure. The prevalence of compensable asbestosis with abnormal lung function was 4-6% for those with 15 or more years of exposure.
