Four cases of pulmonary pseudallescheriasis in patients with healed pulmonary tuberculosis are described. All four patients had a long history of antituberculous chemotherapy for pulmonary tuberculosis, but continuous sputum negativity for acid fast bacilli indicated apparent recovery from tuberculosis. They, however, complained continued intermittent hemoptysis and chronic cough. Although their chest roentgenograms did not show a clearcut mycetomal shadows in preformed cavitary lung lesions, Pseudallescheria boydii or Scedosporium apiospermum was repeatedly isolated from serial sputum specimens collected at different days for a period of over half an year or two years and their serial serum specimens produced precipitin bands with home-made antigen from 8-week old culture filtrate of P. boydii. Second fungus was isolated from sputum specimens of two patients and one was Candida albicans and the other was Aspergillus fumigatus. Sera from both patients reacted with antigens of those second fungi. Unfortunately pulmonary function of three patients did not allow surgical excision of the infected area and one patient refused surgery.

The purpose of this study is to evaluate the current performance of the public services for families in crisis by analyzing the family empowerment service in Healthy Families Support centers. We analyzed performance data of the family empowerment service provided by 25 Healthy Families Support Centers from 2011 to 2013. The results are as follows; First, the number of families in crisis which received public services from the family empowerment service by the Healthy Family Support Centers in 2013 were less than the number in 2011, but increased from 2012. Second, according to the types of crisis, school violence was the most service needed family crisis in 2011, and it was suicide in 2012 and 2013. Third, in the specific services in emergency support for families and family function recovery program, Psychological and emotional support services were the most offered services during 3 years. Accordingly, efficiency of the programs and services in terms of budget is higher than that of any other services. Fourth, analysing the evaluation results of amily empowerment services in 2014, we found that its network is still heavily weighted in certain side by the lack of the utilization and the foundation of the network.

In order to study the effect of CPS in the treatment of atopic dermatitis (AD), its role on various immune related cytokines were tested. Levels of liver and kidney function markers such as ALT, AST, BUN in NC/Nga mice were all normal indicating no toxicity in CPS treated group. Significant recovery from AD could be observed in CPS treated group through naked eye observation. Dermatitis index was significantly decreased after 11, 12, and 13 weeks of treatment. CD4+, CD8+, CD3+ /CD69+ immune cell ratio in DLN were decreased significantly by 37.2%, 49%, 20.8% in CPS treated group. CD4+ and CD11b+ /Gr-1+ immune cell ratio in dorsal skin were decreased significantly by 50.8% and 59.2% in CPS treated group. Expression of IL-4, IL-5, IL-6, IL-13 and TNF-${\alpha}$ in spleen were decreased by 78.8%, 97.8%, 64.7%, 73.6%, and 68.4%, respectively in CPS treated group. The results above strongly indicated the significant immune modulatory effect of CPS and thus clinical application of CPS on AD treatment.

The objective of this study was to analyze the influences of forest management activity on the diameter distribution of Larix kaempferi Carriere stands in South Korea. We used 232 managed stands data, 47 unmanaged stands data of National Forest Inventory for this study. We employed the Weibull distribution function for estimating diameter based on percentiles and parameter recovery method. The results revealed that the average diameter breast height movements and growth of tree in the managed stands higher than the unmanaged stands according to the scenario: age, site index, and tree density change. The finding shows the percentage of the total amount of large class diameter was also high in the managed stands. The results of this study could be apply for the estimation of multi-products of timbers per diameter classes and stand structure development for Larix kaempferi Carriere stands in South Korea.

The aim of this study was to determine the therapeutic effects of beauty care on negative mental health, including stress and depression. Nail care, massage care, and makeup were used as programs for beauty therapy. Qualitative research was conducted with six female participants over five-month period. After interviewing the subjects in advance, beauty care treatments were performed every week 4 weeks in the following order: nail care, massage, and makeup. The results are as follows, First, the participants perceived beauty care in the form of 4 concepts: "courtesy in social life," "investment in oneself," "self-satisfaction," and "self-care." Second, the effects of beauty therapy were categorized as "psychological effects," "confidence," "behavioral changes," "evaluation of others," and "positive social effects." Third, each subject showed different psychological effects during the process when the function of the therapy took effect through the beauty care treatment. It was confirmed that confidence levels increased as a result of treatment through the process of becoming re-aware of oneself. Positive statements from the participants included: "I want to go out," "I have become kind and positive to others," "I have become more active in a given task," and "It seems that my work ability is improving." Finally, t-test results for self-esteem, depression, and stress showed there were significant differences in self-esteem and depression. This confirmed that self-esteem increased, and depression decreased after the beauty care treatment.

In this study, the application of a medical compression sleeve of Moisture Responded Transformable(MRT) fibers to the treatment of lymphedema after surgery in breast cancer patients was investigated. MRT fibers were manufactured with PET and Nylon6 bi-component cross-section yarns, and compression sleeves of sleeves 1, 2, 3, and 4 were knitted in order of size, and then the physical properties and clinical tests were evaluated. As a result, the pressure of compression sleeve in wrinkle was the lowest in sleeve 1 with 3.81 kPa, and the highest in sleeve 4 with 5.22 kPa. Elastic recovery rate is that all parts except the top of the sleeve 1 exhibited 100%. The air permeability was good at 12.1 ~ 16.1 cm³/cm²/sec, and peeling was also comparatively excellent as grade 3. In addition, the weight of the compression sleeves 1, 2, and 3 decreased as 18.3 ~ 23.0 g/m² depend on size, while the compared sample was heavier with 17.39 ~ 32.61 g/m². In lymphoscintigraphy test, it was confirmed that the function of remaining lymph node was good in all patients. Although there were no differences between samples in skin irritation and tightness in wearing comfort, the manufactured sleeves showed better fit, lightness, fashion and breathability than the comparable sleeves.

The continuous increasing of the global demand of copper and nickel metals raises the interest in developing alternative technologies to produce them from copper sulfide ore. Also, in line with Egypt's vision 2030 for achieving the sustainable socioeconomic development which aims at developing alternative and eco-friendly technologies for processing the Egyptian ores to produce these strategic products instead of its importing. These metals enhance the advanced electrical and electronic industries. The current work aims at investigating the recovery of copper and nickel from Abu Swayeil copper ore using pug leaching technique by sulfuric acid. The factors affecting the pug leaching process including the sulfuric acid concentration, leaching time and temperature have been investigated. The copper ore sample was characterized chemically using X-ray fluorescence (XRF) and scanning electron microscope (SEM-EDX). A response surface methodology develops a quadratic model that expects the nickel and copper leaching effectiveness as a function of three controlling factors involved in the procedure of leaching was also investigated. The obtained results showed that the maximum dissolution efficiency of Ni and Cu are 99.06 % and 95.30%, respectively which was obtained at the following conditions: 15 % H₂SO₄ acid concentration for 6 hr. at 250 ℃. The dissolution kinetics of nickel and copper that were examined according to heterogeneous model, indicated that the dissolution rates were controlled by surface chemical process during the pug leaching. The activation energy of copper and nickel dissolution were 26.79 kJ.mol^-1 and 38.078 kJ.mol^-1 respectively; and the surface chemical was proposed as the leaching rate-controlling step.

Ginsenosides are divided into two groups based on the types of the panaxadiol group (e.g., ginsenoside-Rb1 and -Rc) and the panaxatriol group (e.g., ginsenoside-Rg1 and -Re). Among them, ginsenoside-Re (G-Re) is one of the compounds with the highest content in Panax ginseng and is responsible for pharmacological effects. However, it is not yet well reported if G-Re increases the hemodynamics functions on ischemia (30 min)/reperfusion (120 min) (I/R) induction. Therefore, in the present study, we investigated whether treatment of G-Re facilitated the recovery of hemodynamic parameters (heart rate, perfusion pressure, aortic flow, coronary flow, and cardiac output) and left ventricular developed pressure (${\pm}dp/dt_{max}$). This research is designed to study the effects of G-Re by studying electrocardiographic changes such as QRS interval, QT interval and R-R interval, and inflammatory marker such as tissue necrosis factor-${\alpha}$ (TNF-${\alpha}$) in heart tissue in I/R-induced heart. From the results, I/R induction gave a significant increase in QRS interval, QT interval and R-R interval, but showed decrease in all hemodynamic parameters. I/R induction resulted in increased TNF-${\alpha}$ level. Treatment of G-Re at 30 and $100{\mu}M$ doses before I/R induction significantly prevented the decrease in hemodynamic parameters, ameliorated the electrocardiographic abnormality, and inhibited TNF-${\alpha}$ level. In this study, G-Re at $100{\mu}M$ dose exerted more beneficial effects on cardiac function and preservation of myocardium in I/R injury than $30{\mu}M$. Collectively, these results indicate that G-Re has distinct cardioprotectective effects in I/R induced rat heart.

In the early days of open heart surgery, acute respiratory failure following extracorporeal circulation was a significant deterrent to an uncomplicated recovery. Although a marked improvement in prevention and treatment of postoperative respiratory failure has been achieved, the problem has not been completely eliminated and continues to be a causative factor in morbidity and mortality Fates following open heart surgery. We have attempted to evaluate postoperative respiratory failure in patients undergoing cardiac operation with the aid of extracorporeal circulation. Our series comprised 92 patients who underwent elective open heart surgery at the Department of Thoracic and Cariodvascular Surgery, School of Medicine, Kyungpook National University, from January, 1980 to December, 1982. In our study, the overall incidence of acute respiratory failure following open heart surgery was 18.8 percent. The duration of extracorporeal circulation in a series of 18 patients who developed postoperative respiratory failure [Group B] was longer in the mean value [120.3 minutes] than the uncomplicated 74 patients [Group A] [85.8 minutes]. The duration of artificial ventilation after open heart surgery in Group A averaged 13.4 hours as contrasted with 76.5 hours in Group B. In Group B, the inspired oxygen concentration [FiO2] in artificial ventilation was continued in the higher level than Group A until 18 hours after operation. Upon pulmonary function test performed pre-and postoperatively, residual volume[RV], RV/TLC and FEV 1.0/FVC were remained essentially unchanged following extracorporeal circulation, whereas forced vital capacity [FVC], FEV 1.0 and FEF 25-75% were significantly decreased in the early postoperative days. The incidence of acute respiratory failure was significantly higher in a series of patients who developed postoperative complications, such as re- exploration due to massive bleeding, low cardiac output, acute renal failure and arrhythmias. A total of 9 patients died, giving an overall mortality was 33.3 percent whereas the mortality was only 1.1 percent for patients without respiratory failure.
