Authors purposed to observe activities of occupational health nurses and it's related factors, and to suggest the way that induct better occupational health nurses' activities with questionaire to 87 occupational health nurses who individually work as health manager in the plant. The questionaire included type of plant and number of workers, general characteristics, work conditions, activities, etc. Major findings are as follows. 1. 82.8% of occupational health nurses were third decade. 93.1% graduated junior college or college. And 82.8% were not married. 2. General work conditions: 40.2% were belonged to safety-health section, 98.85% were mere clerks. 60.9% worked less than weekly 44 hours, and an annual salary of 50.6 % was between 10 million and 14 million won. 3. Work condition related to health manager work: there was separated health care room in 94.3%, working period as health manager(occupational health nurse) was less than 5 years in 70.1%, 49.4% had the out-of-health manager work. In 87.4%, occupational physician was appointed, only 6.9% of them were full time, 52.9% of them worked little in the plants. The problems related to workers' health were discussed with industrial nurses in 88.5%. 4. Attitude for their work: 88.5% were thought that their work is important for workers' health care, 57.5% satisfied to work as health manager. In 51.7%, motive to being industrial nurse were the appropriate aptitude. 5. Activities: General medical care in 100% were carried out, in 97.7% works related to general health examination, in 100% works related to special health examination were carried. But works related to use of protective apparatus were carried out in 20.8%. 6. Factors related to level of activities: In cases who solved the health related problems by themselves, the level of activites was significantly higher than in others. In cases there were full time occupational physician, the level of activities was significantly lower. 7. Occupational health nurse's needs: 100% wanted regular education, 89.7% wanted the qualifying examination. As the results, author suggests that the right of self-control is given to occupational health nurses and the work of occupational physician is clearly defined for the induction of the better activities of occupational health nurses.

Despite the remarkable advancements of the modern medicine, the traditional system of medicine (TSM) still serves as a potential primary health care modality in the in low- and middle-income countries. The recent reports suggest that there is a renewed interest has been observed towards TSM in the developed countries too, because of the adverse side-effect of modern medicines. Medicinal plants have been widely serving as a rich source of therapeutic agent. Ethiopia is one of the most reserves rich countries in the world. It is renowned for well-diversified and natural resources in terms of its unique flora and fauna. Ethiopian deep-rooted tradition and culture largely depends on the usage of plants for their religious ceremonies, impressive festivals, traditional medicinal uses and other basic necessities. The present scrutiny is an attempt to understand the omnipotent nature of an Ethiopian Ethnomedicinal plant called Tinjute [vernacular name (local native language, Amharic); Otostegia integrifolia]. There are several studies suggest that Tinjute can be used as a natural medicine or health-promoting agents for various disorders and ailments. Nevertheless, in Ethiopia, it is renowned as an insect repellent to drive-away insect vector of diseases, particularly mosquitoes in the early evening. However, there are many more issues and challenges which must be urgently addressed to scientifically formulate various potent, efficacious, safe and highly selective phytotherapeutic agents and insects' repellent from the Tinjute plant in the near future.

The enzyme squalene synthase (EC 2.5.1.21) catalyzes a reductive dimerization of two farnesyl diphosphate (FPP) molecules into squalene, a key precursor for the sterol and triterpene biosynthesis. A full-length cDNA encoding squalene synthase (designated as TcSqS) was isolated from Taxus cuspidata, a kind of important medicinal plants producing potent anti-cancer drug, taxol. The full-length cDNA of TcSqS was 1765 bp and contained a 1230 bp open reading frame (ORF) encoding a polypeptide of 409 amino acids. Bioinformatic analysis revealed that the deduced TcSqS protein had high similarity with other plant squalene synthases and a predicted crystal structure similar to other class I isoprenoid biosynthetic enzymes. Southern blot analysis revealed that there was one copy of TcSqS gene in the genome of T. cuspidata. Semi-quantitative RT-PCR analysis and northern blotting analysis showed that TcSqS expressed constitutively in all tested tissues, with the highest expression in roots. The promoter region of TcSqS was also isolated by genomic walking and analysis showed that several cis-acting elements were present in the promoter region. The results of treatment experiments by different signaling components including methyl-jasmonate, salicylic acid and gibberellin revealed that the TcSqS expression level of treated cells had a prominent diversity to that of control, which was consistent with the prediction results of TcSqS promoter region in the PlantCARE database.

Korea is a rapidly industrializing nation. As a consequence, more mothers are working outside the home. This trend is likely to continue into the future and raises the problem of infant-toddler care during the mother's working hours. Considering that Korea is making such rapid economic advances, quality care for children of working mothers Is not only desirable but affordable as well. Variety in options for child care is recommended by Beck (1982). Some of the alternatives in child care have been discussed elsewhere (KWDI, 1984). This paper, thus, concentrated on center-based, worksite child care. Because the human environment is the most important aspect of the center, qualified staff and a low ratio of children per staff member is Vital. Philosophy of program and its actualization ensures that the children have a worthwhile experience at the center. The physical plant houses the center and includes provision for space, materials, and equipment for staff and child use in carrying out the program. Adequate health protection is a critical factor in infant-toddler group care programs.

This study investigated 31 selected EDCs(Endocrine Disrupting Compounds) and PPCPs(Pharmaceutical and Personal Care Products) in the influent and effluent of a wastewater treatment plant(WWTP) nearby Seoul metropolitan area. The chemical compounds of EDC/PPCPs detected from the plant influent sample include stimulant, X-ray contrast media and fire retardant. The total amount of each compound class were 59.67%, 20.20% and 9.00% respectively. However, in the effluent sample, the major micropolutants detected were oral beta-blocker(30.54%), fire retardant(20.49%), X-ray contrast media(18.17%). The EDC/PPCPs occurrence levels of this study were somewhat lower than previous domestic studies'. When compared to those of overseas, the values were even lower. Some pharmaceutical compound levels particularly measured in European studies were even several thousand times high. This study then compared PECs(Predicted Environmental Concentration) and MECs(Measured Environmental Concentration) of 9 selected pharmaceuticals compounds. The calculated PECs were substantially different with the MECs, while the occurrence order between the PECs and MECs in terms of concentrations of the compounds were similar.

Quick and accurate understanding of the situation in a severe accident is essential for conducting the appropriate accident management and response using the accident diagnosis information. This study employed deep learning technology to diagnose severe accidents through the major safety parameters transferred from a nuclear power plant (NPP) to AtomCARE. After selecting the major accident scenarios to consider, a learning database was established for particular scenarios affiliated with major scenarios by performing a large number of severe accident analyses using MAAP5 code. The severe accident diagnosis technology, which classifies detailed accident scenarios using the major safety parameters from NPPs, was developed by training it with the established database . Verification and validation were conducted by blind test and principal component analysis. The technology developed in this study is expected to be extended and applied to all severe accident scenarios and be utilized as a base technology for quick and accurate severe accident diagnosis.

This study aimed to investigate the association between plant protein intake and health-related quality of life (HRQoL) in Korean individuals aged 50 years or older. Using the 2016-2018 Korea National Health and Nutrition Examination Survey data, 7,956 participants (3,434 men and 4,522 women) were included in the study. HRQoL was measured using the Euro-quality of life five-dimension (EQ5D), composed of physical function, self-care, daily activities, pain/discomfort, and anxiety/depression problems. The EQ5D estimates were converted into an EQ5D index score. The association between daily intake of plant proteins and HRQoL was evaluated using regression analysis. The intake of total plant protein, legume nut seed (LNS), and fermented bean (FERMB) proteins were all positively associated with HRQoL in both men and women (p < 0.01). Of EQ5D's five dimensions, physical function and daily activities were most commonly associated with plant protein intake. Compared to LNS protein or FERMB protein intake, total plant protein intake showed a better association with HRQoL. In conclusion, a significant association was observed between plant protein intake and HRQoL. It suggests that adequate intake of plant protein might be helpful for the maintenance or improvement of HRQoL in Korean adults.

We experienced a case of nephropathy in chronic lead poisoning. The patient was 43-year-old male who has been working in secondary lead smelting plant for 14 years. On admission, blood pressure was 160/90 mmHg and the others were non-specific. In past history, he received chelating agent administration for lead poisoning irregularly and medicated for gout, and the blood lead concentration was $180.0{\mu}g/dl$ on 2 months before admission. Smoking habit has been 1 pack per day for 15 years and drinking habit has been 1 bottle of Soju per day but less flow. In liver function test, AST/ALT were 27/28 IU/l and $\gamma-GT$ was 456 IU/l. In blood test, Hb : 11.5 g/dl, Hct : 34.0% and basophilic stipplings were found in peripheral blood smear. Chest PA was normal and abdominal ultrasonographic finding was non-specific except fatty liver. In the test of lead exposure indices, $PbB:83.0{\mu}g/dl,\;PbU:28.3{\mu}g/l$, and blood ZPP was $300.0{\mu}g/dl$. And in renal function test, BUN : 31.4 mg/dl, blood creatinine : 2.7mg/dl, blood uric acid. 9.1 mg/dl, urinary albumin : 100.0 mg/g creatinine, urinary $\alpha_1-microglobulin$ : 120.5 mg/g creatinine, urinary $\beta_2-microglobulin$ : $183.8{\mu}g/g$ creatinine, and 24 hours urinary creatinine clearance was 31.9 ml/min. The ultrasonoguided renal biopsy showed the global sclerosis of glomerulus, moderate atrophy and loss of tubule, and interstitial fibrosis in light microscopy. There were diffuse losses of brush border of proximal tubule in electronmicroscopy.
