본 연구는 철강석의 정제후 부수적으로 발생하는 고로슬래그 미분말을 건설분야에 이용하여 고강도콘크리트를 제조하고 이에 대한 여러 가지의 역학적 특성을 알아보고자 하는 것이다. 실험의 주요인자로서 물/시멘트비, 굵은골재의 최대치수 및 시멘트의 종류로서 슬래그시멘트와 보통시멘트를 비교하였으며 제조된 콘크리트의 경화전 특성 실험으로는 슬럼프, 공기량, 응결시간을 측정하고 경화후 압축강도, 할렬인장강도, 휨강도 및 동결-융해 저항특성 실험을 수행하였다. 실험결과 슬래그시멘트와 19mm골재를 사용하고 물/시멘트비가 낮은 경우 높은 강도 발현은 물론 500cycle 이후에서도 상대동탄성계수가 90%이상을 나타내어 동결-융해에 대한 저항성이 매우 우수함을 나타내었다. 또한 슬럼프 경시변화에서도 보통시멘트를 사용한 콘크리트에 비해 슬럼프 손실률이 상당히 적어 유동성을 확보한 고강도 콘크리트의 생산이 가능함으로써 건설분야에 활용될 수 있을 것이다. The purpose of this study is to make high strength concrete using blast furnace slag and is to know the mechanical properties about it. Major variables of experiment are the water/cement ratio, coarse aggregate maximum size, portland and slag as cement type. After measuring of slump, air content and setting time about fresh concrete, compressive, tensile and flexible strength test and freezing-thawing resistance test also were carried out about hardend concrete. The results of test showed a good resistance to become higher than 90% of a relative modulus of elasticity after 506cycles and more strength in case of lower water/cement ratio and coarse aggregate of 19mm with slag cement. Also, concrete using blast furnace slag will make practical application of construction field to be high strength concrete, a small slump loss.

For a large scale civil and architectural structures, mainly steel, concrete and aluminum have been used and weight and corrosion of materials became a major concern. Designing with composite materials is very much complicated. Simple classical theory may yield good results for selecting "initial" sections for preliminary design. D.H. Kim proposed to use the quasi-isotropic constants by Tsai for the preliminary design of the composite primary structures for the civil construction. Also he made simple equation using correction factor. In this paper, the simple formulas developed by D. H. Kim to obtain "exact" values of the natural frequencies of [ABBCAAB]r laminate are compared with reinforcing fiber orientations, are compared with nastural frequencies of bean. This work can be a guideline to obtain data in many other cases.

Background:Since severe tricuspid regurgitation (TR) is an uncommon fi nding which develops in various conditions, the present study aimed to investigate etiology, clinical characteristics, and predictors of reversibility in patients with severe TR. Methods:A total of 232 patients (67. 4±14. 1 years, 80 males) who were diagnosed with severe TR by echocardiography were enrolled. Severe TR was defi ned as vena contracta width greater than 0. 7 cm and systolic fi ow reversal in hepatic veins according to the current guideline of American Society of Echocardiography (ASE). Improvement of TR to moderate or less degree on follow up echocardiography was considered as reversible TR in the present study. Primary end points were adverse events at long-term follow-up. Adverse events were defi ned as all-cause death and operation due to severe TR. Results: Reversible TR was observed in 35 out of 153 patients (23. 0%). Sixty-one patients showed clinical improvement, but the degree of TR was not changed. Forty-nine patients (32%) who did not show clinical improvement despite of medical therapy eventually underwent surgical correction of TR, and 7 patients died. In addition, 17 patients died without operation, so 24 deaths (16%) were observed in total. finally, total adverse events developed in 66 patients (41%) during 2 years of follow-up period. Logistic regression analysis revealed prosthetic mitral valve was the only independent predictors of future adverse events (OR 2. 47, 95%CI 1. 05-5. 77, p=0. 038). Independent predictors of improved TR turned out to be the use of RAAS blockade (HR 3. 02, 95%CI 1. 12-8. 17, p=0. 030) and the use of spironolactone (HR 3. 39, 95%CI 1. 05-10. 90, p=0. 041). Low ejection fraction (LVEF <50%) also had a trend toward the reversibility (HR 2. 82, 95%CI 0. 94-8. 40). Conclusions:Considering results above, reversible severe TR mainly associated with left heart failure and medical treatment should be given before considering surgery for severe TR.

Background: To determine the natural progression of conservatively treated rotator cuff tears, we evaluated changes in radiologic and clinical parameters in patients whose recalcitrant tears were neglected after conservative treatment. Methods: A total of 73 patients with recalcitrant rotator cuff tears in spite of conservative treatment were included in this study. We measured changes in tear size and in the extent of fatty infiltration of the rotator cuff by comparing the initial and final follow-up magnetic resonance imagings (MRIs). To determine factors influencing the change in tear size, we collected the medical history of patients taken at the time of initial admission. Results: The average follow-up period was 20.1 months, and the average increase in tear size across this period was 6.2 mm. In terms of steroid injection, we found that the increases in tear size of the steroid injection group (p=0.049) and of the sub-group that had received more than three steroid injections (p=0.010) were significantly greater than that of the non-steroid injection group. Conclusions: We found that the increase in cuff tear size was on average 6.2 mm across the follow-up period, indicating that neglecting cuff tears may cause them to progress into more severe tears. We also observed that a history of steroid injection might be a possible risk factor for a worse prognosis of cuff tears. Therefore, we suggest that patients with rotator cuff tears and a history of steroid injection are recommended aggressive modes of treatment such as surgery.

The aging of the population is appearing worldwide, and Korea is increasing the aging population faster than any other country. This means that your life as an elderly person will be longer. In order to live happily as an aged person, it is necessary to achieve successful aging. In successful aging, a healthy body is an important factor that determines the life of the elderly. A healthy body is an ecological body, which denotes that one’s mind and body are in a state of harmony. Straightening the elderly body and creating an ecological body by re-bodying the disordered body order is realized through movement. The process of organizing and internalizing these movements is necessary, and in this thesis this process was set as the body design process. This study is a study on the process of body design of the elderly for successful aging and proposes the direction of the following step-by-step design process: First, the process of designing an old person’s body starts with discovering problems while searching his or her body through movement, which necessarily leads to reflection of one’s life. Second, it is important to plan movements from an ecological point of view and perform them continuously and repeatedly to restore body order. Third, from an ecological point of view, it is a stage of practice that regenerates the harmony of consciousness and body. This is a very important process since it involves the continuous practice of movement to regenerate energy by properly re-arranging the body and smoothing circulation. Designing the elderly body in this way is directly related to health, and recovery of health is the first step in successful aging. New perspectives and changes in one’s view point on the elderly body will be an important driving force in re-examining the lives of all of us and fulfilling a healthy old life as an important member of the community.

Purpose: Work-related asthma (WRA) occupies about 10%–30% of all asthma cases. Among 2 subtypes of WRA (occupational asthma [OA] and work-exacerbated asthma [WEA]), the rate of WEA has been reported to increase recently. WRA is described as having worse characteristics than non-WRA (NWRA), while WEA is known to show similar severity to OA in terms of symptoms and exacerbations. However, these data were mainly based on indirect surveys. Ulsan is a highly industrialized city in Korea; therefore, it is estimated to have a high incidence of WRA. This study aimed to identify the characteristics of WRA in the city. Methods: This was a prospective asthma cohort study of individuals diagnosed with asthma and treated at Ulsan University Hospital between Jan 2015 and Dec 2016. Baseline characteristics and work-related inquiry (9 questionnaires) were investigated at enrollment. Various severity indices and job change were then investigated for the longitudinal analysis at 12 months after enrollment. Results: In total, 217 asthma patients completed the study. WRA accounted for 17% (36/217), with an equal number of WEA and OA (18 patients each). Before the work-related survey, only 33% (n = 12) of WRA patients (22% [4/18] of WEA and 44% [8/18] of OA) were diagnosed with WRA by the attending physicians. Compared to the NWRA group and the OA subgroup, the WEA subgroup had more outpatient visits, more oral corticosteroids prescriptions, and trends of low asthma control test scores and severe asthma. The rate of job change was markedly lower in the WEA subgroup than in the OA subgroup (20% vs. 5%). Conclusions: The overall prevalence of WRA (17%) was similar to those of previous studies, but the share of WEA was high (50% of WRA). WEA was more severe than OA or NWRA. The possible reason for this severity is ongoing workplace exposure.

Overcrowding of emergency departments is a growing problem. Delays in admitting patients to inpatient units have been reported as a contributing factor to overcrowding. Overcrowding in ED results in many patients not receiving needed care and impairs the ability of the ED provider to meet the needs of those patients that are treated. The effect of the critically ill patients on the overcrowded emergency department make emergency physicians frustrated. So we created the 'special unit for observation' of critically ill patients and managed them continuously and closely. The special unit for observation have 4 physical beds and monitors and 2 ventilators. One nurse and senior ED residents were asigned to the management of the patients in the special unit. 160 patients(3.4% of all ED visits) admitted to special unit during the period of March 1, 1996 to May 31, 1996. we could continue assessment and management of critically ill patients without psychologic strain or burnout generated by overcrowding. We think that special unit for critically ill patients is a very effective alternative to overcrowded ED.

Viral infection would have a deleterious impact on renal graft survival, and increase the morbidity and mortality in renal transplant patients. The clinical diagnosis of viral infection in renal transplant is difficult. Standard procedure for identification of viruses is tissue culture, but it takes much time. Serological diagnosis of viral infection does not always represent the clinically apparent infections. Recently, the value of direct virus detection by nonisotopic DNA probe in situ hybridization (ISH) has been introduced. To evaluate the potential role of cytomegalovirus(CMV), Epstein-Barr virus(EBV) and herpes simplex virus(HSV) on renal graft rejection, eleven rejected kidney allograft specimens were analyzed by ISH with biotinylated DNA probes. CMV-infected lung tissue, EBV-infected lymph node tissue and HSV-infected skin tissues were used as positive controls. One specimen showed positive hybridization with CMV probe and one with EBV probe. The whole procedure can be completed in less than 1.5 hours. In conclusion, we suggest the colorimetric method for ISH could be a powerful tool of detection of viruses in tissues without the need of radioactive probe. Cytomegalovirus, Epstein-Barr virus and herpes simplex virus may be of minor importance in triggering allograft rejection in Korea.

The herbal extract(YMT_02) is a modified extracts from Yukmijihwang-tang(YMJ) to promote memory-enhancing. The YMJ extracts has been widely used as replenishing yin and tonifying the kidneys herbal medicine for hundred years ia Asian countries. The purpose of this study is to: 1) quantitatively evaluate the memory-enhancing effect of YMT_02 by passive avoidance test, 2) statistical evaluation of candidate gene expression (pentraxin, PEP-19, transthyretin) in rat hippocampus. The hippocampi of YMT_02 and control group were dissected and mRNA was further purified. After synthesizing cDNA using oligo-dT primer, the cDNA were applied to Real Time PCR. The results were as follows : 1) passive avoidance test showed enhancing memory retentin by YMT_02 treatment, 2) expression of pentraxin, that accelerate degenerating of neuronal cell, was significantly decreased, 3) the mRNA of genes that has been known to be associated with protecting neuronal cell degeneration, such as PEP-19 and transthyretin, were significantly increased upon YMT_02 treatment. From above results, the administration of YMT_02 which tonify the function of Kidneys could enhance the ability of memory and learning. In addition, the administration of YMT_02 enhance memory retention through modulating particular gene (pentraxin, PEP-19, transthyretin) expressions in hippocampu
