In this country, mackerel landing, sorting, and packing are mostly performed manually, which is time consuming and labor intensive. An unloading automation system saves time and labor by automating the landing, sorting, and packing processes. Casers are devices for manufacturing packing boxes for fish used by unloading automation systems. The caser design in this study is for mackerel packing boxes. This caser makes a packing box based on a press using the caser's slide crank. When the caser makes a packing box, the manufacturing sequence is determined by the caser's production guide and assisting rod. The caser design in this study is simulated using a multi-body dynamics program. The simulation is used to analyze the caser and to visualize the box-making sequence.

We studied the influence of culture conditions on the acid tolerance of Lactobacillus casei YIT 9018 in artificial gastric juice with respect to relative amount of membrane bound ATPase and their biochemical characteristics. With raising incubation temperature from 30.5$\circ$C to 40.5$\circ$C and lengthening incubation time from exponential phase to late stationary phase, the acid tolerance of L. casei YIT 9018 was increased. As acid tolerance enhanced, C$_{18:1}$ content of membrane fatty acid was reduced and C$_{19:0 cyclo}$ was enriched but the others were not changed greatly. At high ATPase activity, proton permeability was relatively low but this phenomenon did not correspond to acid tolerance. In conclusion, it was considered that changes of C$_{18:1}$ and C$_{19:0 cyclo}$ were closely related to the acid tolerance of L. casei YIT 9018.

A Study to evaluate the diagnostic significance of M. pneumoniae infection by measurements of cold agglutinin and antimycoplasma antibody titers is performed with 191 pediatric patients who have visited Yeungnam University Hospital during the period through January to July, 1987. Forty eight of 191 cases made follow up tests feasible. The results obtained are as follows : 1. It is necessary to perform routine combined measurements of cold agglutinin and antimycoplasma antibody titers for the all pediatric pneumoniae caser since a large proportion of pneumonia in children is caused by M. pneumoniae. 2. For the diagnosis of M. pneumoniae infection, measurements of cold agglutinin titers alone seems to be les significant than to check both cold agglutinin and antimycoplasma antibody titers. 3. The measurement of antimycoplasma antibody titer appeared to be more specific than cold agglutinin test in the diagnosis of M. pneumoniae infection. 4. The present study urges the necessity of follow up study of cold agglutinin and antimycoplasma antibody titers for those who initially presented with normal titers in both tests, but are clinically suspected for M. pneumoniae infection.
