This study has made use of the work sampling for work analysis and productivity of food service institutions centering on 3 general hospitals of 400∼600 beds and centralized service system in Seoul. The results were as flollows; 1. In the mean work percent of dietitians: The indirect work functions marked the highest, as it was 22.0% for the direct work functions, 57.4% for the indirect work functions and 20.6% for the delays. Among the indirect work functions, the decreasing order was original clerical (38.1%), instruction or teaching (8.5%), conference or interview (8.5%), and appraisal (2.3%). 2. In the mean work percent of clerical personnels: The direct work functions (67.2%) marked the highest. Among those, routine clerical was 64.3%, and receiving was 2.8%. 3. In the mean work percent of workers: The direct work functions (77.4%) marked the highest. Among those, the decreasing order was service (24.7%), cooking (22.5%), cleaning (18.2%), and transportation (10.3%). 4. Work percent per labor hour: Dietitians usually continued to work even during the lunch time. In case of clerical personnel working in turn, work percent was high even during the lunch time, however in the other case, it was very low. It was shown that the workers had lunch and break time after every their service. 5. The number of meals served per labor hour were 6.3 meals, and labor time spent per served meal 9.8 minutes.

200 patients admitted to the Chest Surgery Department of Jeonbug National University Hospital from January, 1974 to December, 1981 were analyzed clinically. The ratio of male to female was 7: 1, which showed male predominance. Distribution of patients according to age disclosed that over half [62%] of the patients was social age between 20 and 49 years. The most common cause of chest trauma was traffic accident [39%], and the next were stab wound, fall down [17.5%], and hit [8.5%] in decreasing order. Common lesions due to chest trauma were as follows; rib fracture [51%], hemopneumothorax, hemothorax, and pneumothorax in decreasing number. The most common cause of rib fracture was traffic accident [50%] and the associated organ injuries were long bone fracture, head injury, spine and pelvic bone fracture, spleen rupture, and liver laceration. Hemothorax, pneumothorax, and hemopneumothorax were treated with insertion of thoracic catheter in 90 cases, pure thoracentesis in 11 cases, and emergency thoracotomy in 11 cases. In flail chest, 6 patients were treated by intramedullary insertion of Kirschner`s wire and the results were good. The incidence of complication was 17%, including atelectasis [11 cases], pyothorax, fibrothorax, pneumonia, and acute respiratory failure. Four patients were died [2%], and the causes were acute respiratory failure in 2 cases, spinal cord injury in one case and head injury in one case.

Up to date, the dual scanning method has been adopted to decrease address-ing period in AC PDP. In this case, addressing period can be reduced, but the driving circuit cost should be increased. In this study, to increase addressing speed we have studied the relationship between addressing speed and cell structure. That is to say, we varied the thickness of dielectric layer on the front glass, the thickness of white back and the height of barrier rib on the rear glass. So, we found that the addressing time was decreased 4% with decreasing 5um thickness of dielectric layer on the front glass and 2um thickness of white back on the rear glass. Also in case of decreasing the height of barrier rib, addressing time was decreased about 4% per 10um.

The Japanese language, as a typical agglutinating language, permits large noun phrases (NP) containing ten or more morphemes. In this paper, we argue that the nature of the NP in Japanese is changing. Our data are drawn from the Balanced Corpus of Contemporary Written Japanese. We conduct a series of apparent-time studies of ongoing changes in complex NPs. We first examine the length of compound nouns, followed by the usage of bound suffixes. We then examine ongoing changes in complex NPs that contain genitive case markers. Finally, we examine noun incorporation. All of our studies show a trend towards shorter, less complex NPs. Furthermore, our results suggest that the usage rate of phrases that modify the noun inside the NP (compound nouns, bound nouns, NPs containing genitive case, noun incorporation) appears to be decreasing over time. On the other hand, the usage rate of modifying material outside of the NP (positional phrases, relative clauses) appears to be increasing over time. We conclude by suggesting that our results reflect a diachronic change of decreasing synthetic morphology and increasing analytic morphology. We end by pointing out the implications of this work on our understanding syntheticity and analyticity.

In order to study the effects of iron and zinc on the lead poisoning of rats, lead with iron and zinc, or lead alone were administered orally to a total of 98 adult rats of Sprague-Dawley Species. The concentrations of lead, zinc, and iron were measured by atomic absorption spectrophotometer at every 20 days intervals of 20th, 40th, 60th, 80th and 120th day as a final measurement. Those datas were analysed and compared with those of control groups. The results were summarized as follows; 1. The concentration of lead in blood, bone. and liver tissues kept increasing in case of lead exposure group whereas it started decreasing at 60-80th day when concentration of zinc started increasing in case of combined exposure group. However, in kidney tissue, the concentration of lead in combined exposure group kept increasing up to the end of observation showing special high concentration at the final measurement at 120th day. 2. Concentration of zinc in blood and liver tissues had increased from 60-80th day in case of combined exposure group. 3. Concentration of iron in blood showed decreasing from $44.15{\pm}9.67\;to\;32.44{\pm}2.69{\mu}g/ml$ in case of lead exposure group, whereas it showed constant level of $47.50{\sim}45.65{\mu}g/ml$. However, in liver tissue it kept constant as control did from 40th to 60th days, but from 100th day on it started increasing to show much higher concentration than control.

This study analyzes the change of the basic characteristics of pavement concrete according to the reinforcement of macro-fiber and the results of the study can be summarized as follows. In the case of the compressive strength of the concrete, the fiber reinforced pavement concrete shows a small decreasing level compared to the basic mixing of pavement concrete (hereafter referred as 'Plain') based on the aging of 28 days. In particular, the polypropylene fiber made in Korea represents a decrease in the strength about 12% compared with that of the Plain. In the case of the tensile strength, it shows certain improvements in the tensile performance compared with that of the Plain. In particular, in the case of the polyvinyl alcohol fiber that shows the largest improvement in tensile performance, it shows an increase in its strength about 21%. In the case of the bending strength, there are no improvements in its strength in the fiber reinforced concrete compared to that of the Plain.

Silk/Cotton fabrics were treated with butanetetracarboxylic acid(BTCA) to improve crease recovery and anti-shrinking properties at various curing temperatures and pH values. We investigated the effects of finishing conditions on add-on of BTCA, bending property(E, 2HB), wrinkle recovery angle, shrinkage, and dyeing properties. The Add-on of BTCA increased with increasing curing temperature and concentration. Crease recovery was improved with decreasing shrinkage. Maximum add-on of BTCA was showed at pH 2.5. In case of dyeing and mercerization, silk side treated with BTCA was more flexible than untreated, whereas cotton side was more stiff. In dyeing after mercerization, B and 2HB values were higher and K/S values were doubled nearly. The hand of fabric improved with decreasing B and 2HB by the BTCA treatment. BTCA treatment after reactive dyeing improved crease recovery, and caused no change of color difference. However, BTCA treatment after reactive dyeing didn't improve crease recovery, whereas B and 2HB were decreased considerably by the treatment.
