This study aims to identify the influence of the satisfaction of the elderly with their participation in fitness on the expectation of support and family function. First, overall satisfaction and satisfaction with service quality out of satisfaction factors with the participation in fitness significantly affected family cohesion and family adaptability, and they significantly affected family adaptability in psychological satisfaction factors. Second, all of the sub-factors of the satisfaction with the participation in fitness significantly affected the expectation of support. Third, the satisfaction with fitness of the elderly directly affected family cohesion and family adaptability, which posted .162 and .239 respectively. Plus, the satisfaction with the participation in fitness indirectly affected the expectation of support, which posted .032 and directly affected the expectation of support, which posted .722. Also, family cohesion directly affected the expectation of support, which posted -.101, and family adaptability directly affected the expectation of support, which posted .201.

Carbon monoxide (CO), a reaction product of cytoprotective enzyme heme oxygenase-1 (HO-1), is a gaseous messenger with anti-proliferative, anti-apoptotic, and anti-inflammatory actions in many cell types. Here, we investigated the role of CO on the process of monocyte differentiation induced by phorbol 12-myristate 13-acetate (PMA) in human monocytic THP-1 cells. CORM-2 (tricarbonyldichlororuthenium (II) dimer, $Ru2Cl_4(CO)_6$), a CO-releasing compound, decreased a marked cell adherence with a slight reduction of proliferation in monocytic THP-1 cells treated with PMA. And, CORM-2 significantly inhibited expression of differentiation markers such as CD14, CD11b plus CD18 (macrophage-1 antigen, Mac-1 or complement receptor 3, CR3) and phagocytosis of carboxylate-modified red fluorescent latex beads, in PMA-stimulated THP-1 cells. For the further experiments, differentiation of PMA-treated cells was enhanced after the initial 2 days stimulus by removing the PMA-containing media then incubating the cells in fresh media for a another 4 days. And, we observed the secretion of inflammatory cytokines and phagocytosis in differentiated macrophages. Treatment with CORM-2 significantly abolished the secretion of IL-6, $TNF-{\alpha}$ and phagocytosis using fluorescence-conjugated E. coli (K-12 strain) bioparticles in lipopolysaccharide (LPS)-stimulated differentiated macrophages. In conclusion, these results suggest that CO inhibits the differentiation of monocytic THP-1 cells as well as the activation of differentiated macrophages.

A retrospective analysis of various characteristics in 32 limited stage small cell lung cancer patients treated at the Department of Therapeutic Radiology in Kangnam St. Mary's Hospital, Catholic University Medical College from April 1983 to September 1991, was carried out to identify factors which had prognostic significance for survival from initiation of radiation therapy. There were 26 men and 6 women. Median age was 63 years (range: 24-78 years). The follow up duration was 1.5 to 44 months (median: 9 months). External radiation therapy was done with daily 160-180 cGy,5 fraction/week, total of 1000-6660 cGy (median: 4500 cGy) to the mediastinum by 6 MV linear accelerator. Of 32 Patients, 27 ($84.4{\%}$) patients were treated with combined modality (chemotherapy plus radiation therapy), and 5 ($15.6{\%}$) patients were treated with radiation therapy only. Complete responders were 12 patients ($37.5{\%}$), partial responders were 11 ($34.4{\%}$), and no responders were 9($28.1{\%}$). Karnofsky performance status over 70 (p<0.04), chemotherapy regimen (CAV, PV, and CAV+PV) (p<0.04),6 or more cycles of chemotherapy (p<0.007), radiation therapy over 4500 cGy (p<0.03), and radiation therapy responder (CR+PR) (p<0.003) showed a significantly favorable influence on 1 year survival rate. Age (p=0.545), sex (p=0.666), presence of superior vena cava syndrome (p=0.719), prophylactic cranial irradiation (p=0.217), and radiation therapy duration (p=0.491) had no effect on survival. Radiation induced side effects were transient esophagitis in 11 ($34{\%}$), general weakness in 9($28{\%}$), gastrointestinal symptoms in terms of nausea, vomiting and indigestion in 5 ($15{\%}$) and leukopenia in 1 ($3{\%}$).

This study evaluated calcium hydroxide (slaked lime) and a combination of plant extracts ('natural product'; clove, cinnamon, and saponin; 1:1:1 ratio) as acaricidal control mechanisms for poultry red mites. Red mite susceptibility was evaluated after treatments with 10% slaked lime, 20% slaked lime, and 1% natural product. The duration of the acaricidal effect was also tested at 0, 10, 30, and 60 min after treatment using 20% slaked lime, 1% natural product, or a mixture of both. In the in vitro experiment, the slaked lime treatments were 73.2% (10% slaked lime) and 85.1% (20% slaked lime) effective on red mites. In acaricidal effect of control materials over times, with 20% slaked lime, the acaricidal effect decreased to 50.7% after 30 min, and 12.7% after 60 min (P<0.05). With 1% natural product, there was no acaricidal effect after 30 min (P<0.05). With 20% slaked lime +1% natural product, all of poultry red mites died until 30 min, and 92.9% after 60 min (P<0.05). On the farm, poultry red mites were observed that the number of poultry red mites increased 7,923 from 36 to 45 weeks, but then decreased to 483 after 20% slaked lime plus 1% natural product treatment. These results indicate that combining slaked lime and plant extracts effectively control poultry red mites.
