While human error happens repeatedly in the semiconductor industry in Korea, which has brought a tremendous loss from manpower, welfare etc., there are limitations to human error prevention activities. When a semiconductor company introduces new machines and facilities from Japan or Germany, the companies often do not consider human factors in the design. Also, semiconductor companies are so occupied with promoting increased productivity, their attention to human errors has been pushed aside. Negative aspects of technical exchange associated with safety management are one aspect of the industry's nature. A semiconductor company recently began acknowledging on the back of TQM(Total Quality Management) that human error has a decisive effect on the safety. There are a number of uncontrollable and hard to handle event sets because the nature of these events with a human error may often be threatened or very intensive. It is strongly required that systemic studies should be performed to grasp the whole picture of a current situation for hazard factors. This study aims to examine the human error approach through the case of human error prevention field activities in a semiconductor industry compared with the activities and experience in nuclear power plants.

The purpose of this study was to explore the perceived quality of life of Korean university students'. The perceived quality of life was composed of three dimensions: emotion, cognitive efficiency, and satisfaction. The study results were as follow: 1. Korean university students felt more positive emotions when they spent time for social activities. 2. In the cognitive efficiency, social activities also scored highly of 5 questions, but in the item of "awareness of another person's eye", productive activities were higher. 3. Korean university students were more satisfied with themselves when they spent time for productive activities. However, they were more satisfied with their work itself when the work was social activities. 4. Korean university students' emotions, cognitive efficiencies, and satisfaction were significantly different by socio-graphic variables and context.

The study aims to investigate factors affecting subjective well-being of the pre-elderly. The factors considered were 'leisure activities', 'leisure activities', 'leisure satisfaction' and some 'background variables'. The subjects were 251 pre-elderly persons ($50{\sim}60$ years old) who completed the questionnaire assessing the variables for the study. The results include: 'Life satisfaction' of the pre-elderly is affected with the variables of 'health', 'financial situation', 'leisure activities without their partner', 'leisure activities with family', 'local community leisure activities', 'social satisfaction' and 'psychological satisfaction in leisure activities'. Their emotion is positively influenced by the variables of 'health', 'financial situation', 'leisure activities without a partner', 'leisure activities with family', 'social satisfaction in leisure activities'. and negatively influenced by the variables of 'age', 'health', 'financial situation', 'leisure activities without a partner', 'social satisfaction in leisure activities'. In conclusion, leisure satisfaction and a partner for leisure activities are more important determinants than frequency of leisure activities in pre-elders' subjective well-being.

Comparative cytotoxic activities of petroleum ether soluble fraction from various ginsengs of Panax species were evaluated using A549 (human lung adenocarcinoma) and SK-OV-3(human ovary carcinoma) cancer cell lines. Korean red ginseng, Korean white ginseng, American ginseng and Canadian ginseng were found to show more potent cytotoxicitles on A549 and SK-OV-3 cell lines than Chinese red ginseng, Japanese red ginseng and Sanchi ginseng. It is noteworthy that especially, red ginseng prepared from the root of Panax ginseng cultivated in Korea shows relatively stronger cytotoxic activities than those cultivated in China and Japan.

Changes in the activity of alkaline phosphatase (ALP) isoenzymes and isoforms in human serum have a major diagnostic value, therefore the regulation of ALP activities is a valuable target for therapeutic interventions. To assess the pharmacological activity of retinoids, i.e., all-trans retinoic acid and 13-cis retinoic acid, their tissue-specific inhibitory effect on human serum ALP activity was elucidated by chemical inhibition methods, heat-sensitive inactivation, and wheat-germ lectin precipitation test. Retinoids showed significant inhibition of the total ALP activity in human serum at a concentration of 5 mM. All-trans retinoic acid (5 mM) and 13-cis retinoic acid (5 mM) inhibited ALP activities by up to 12% and 15%, respectively, compared to that by guanidine hydrochloride (200 mM). L-phenylalanine (100 mM) and urea (30 mM) had no further inhibitory effect on ALP activities in human serum pretreated with retinoids (5 mM). Retinoids significantly inhibited ALP activities by up to 20% compared with that of tetramisole (30 mM). The ALP activities in retinoid-pretreated serum remained unchanged after the heat inactivation process. These results suggest that retinoids are inhibitors of the intestinal ALP isoenzyme. Remarkably, retinoids revealed potent inhibitory activities against ALP in wheat-germ lectin precipitant serum, indicating that they also function as inhibitors of the bone ALP isoform. The results show that retinoids inhibit the specific tissue-derived human serum ALP activities, moreover, the inhibitory effect of retinoids against bone ALP activity suggests their clinical utility as monitoring and prevention of metastasis of bone cancer.

The ability of fibroblasts attached to teeth is paramount important in reestablishing the lost connective tissue attachment after periodontal therapy. The migration and proliferation of periodontal ligament cells are desired goal of periodontal regeneration therapy. PDGF is well known to regulate the cell activity of mesenchymal origin cell. Tobacco contains a complex mixture of substance including nicotine, various nitrosamines, trace elements, and variety of poorly characterized substances. Human gingival fibroblasts and periodontal ligament cells were cultured from extracted tooth for non-periodontal reason. Cultured human gingival fibroblasts and periodontal ligament cells in vitro were treated with PDGF, nicotine in time dependent manner. Cellular activities were determined by MTT assay. The purpose of this study was to determine the effects of Nicotine and PDGF, respectively and the effect of PDGF presence of nicotine on human gingival fibroblasts and periodontal ligament cells. The results were as follows : 1. In the cell activities of human gingival fibroblasts and periodontal ligament cells were similar or decreased to control value at 1st day. At 2nd day, cellular activities of both group were increased to control value. At 3rd day, cellular activities of both group were returned to the control value. 2. In the cell activities of PDGF on human gingival fibroblasts and periodontal ligament cells, cell activities significantly increase from control group on periodontal ligament cells compared to gingival fibroblast group at 3rd day. 3. In the cell activities of PDGF and nicotine combined application on human gingival fibroblasts and periodontal ligament cells, it seems likely that the nicotinic effect of gingival fibroblasts were higher than periodontal ligament cells and the PDGF effect of periodontal ligament cells were higher than gingival fibroblasts. This results suggested that PDGF might stimulate the selective growth on periodontal ligament cells.

We propose a novel deep neural network model for detecting human activities in untrimmed videos. The process of human activity detection in a video involves two steps: a step to extract features that are effective in recognizing human activities in a long untrimmed video, followed by a step to detect human activities from those extracted features. To extract the rich features from video segments that could express unique patterns for each activity, we employ two different convolutional neural network models, C3D and I-ResNet. For detecting human activities from the sequence of extracted feature vectors, we use BLSTM, a bi-directional recurrent neural network model. By conducting experiments with ActivityNet 200, a large-scale benchmark dataset, we show the high performance of the proposed DeepAct model.
