Our study is to determine the presence of endometrial intraepithelial neoplasia (EIN) in endometrial biopsy specimens classified by the 1994 World Health Organization (WHO) criteria for endometrial hyperplasia. Endometrial biopsy specimens that were stained with hematoxylin and eosin (HE) were examined and categorized by the WHO 1994 criteria and for the presence of EIN as defined by the International Endometrial Collaborative Group. ${\beta}$-catenin expression was examined by immunohistochemistry. A total of 474 cases of HE stained endometrial biopsy tissues were reviewed. There were 379 cases of simple endometrial hyperplasia, 16 with simple atypical endometrial hyperplasia, 48 with complex endometrial hyperplasia, and 31 with complex atypical endometrial hyperplasia. Among the 474 endometrial hyperplasia cases, there were 46 (9.7%) that were classified as EIN. Of these 46 cases, 11(2.9%) were classified as simple endometrial hyperplasia, 1 (6.3%) as simple atypical endometrial hyperplasia, 6 (12.5%) as complex endometrial hyperplasia, and 28 (90.3%) as complex atypical endometrial hyperplasia. EIN was associated with a higher rate of ${\beta}$-catenin positivity than endometrium classified as benign hyperplasia (72% vs. 22.5%, respectively, P<0.001), but a lower rate than endometrial adenocarcinoma (72% vs. 96.2%, respectively, P<0.001). In benign endometrial hyperplasia, high ${\beta}$-catenin expression was noted in the cell membranes, whereas in EIN and endometrial adenocarcinoma high expression was noted in the cytoplasm. In conclusion, EIN is more accurate than the WHO classification for the diagnosis of precancerous lesions of the endometrium.

In order to determine the content levels of trace metals in common salts, 64 bay salt samples were collected from three producing districts and 33 bay salt samples, 32 remade salt samples and 5 fine salt samples were collected from 7 major cities in Korea, from August to September 1987. These were analysed for content levels of Pb, Cd, Cu, Zn and Mn using Atomic Absorption Spectrophotometer. The results were as follows: 1. Lead contents in three type salts were N.D. - 1081.9 $\mu$g/kg and fourteen percent of the 114 samples exceeded the World Health Organization(WHO) criteria of 100$\mu$g/kg. Cadmium contents of samples were N.D.- 382C.5 $\mu$g/kg and five percent of the 114 samples were over the Spanish criteria of 500 $\mu$g/kg. Copper contents of samples were 8,9-214.9 $\mu$g/kg and there was not a sample over the World Health Organization(WHO) criteria of 500 $\mu$g/kg. Zinc contents ranged N.D. - 342.9 $\mu$g/kg and Manganese contents ranged N.D.- 8.31 mg/kg. 2. The comparison of heavy metal contents among the bay salts from three producing districts was significantly different in Pb, Cd and Cu contents. 3. The comparison of heavy metal contents between the bay salts and remade salts was not significantly different in Pb, Cd and Cu contents. 4. The contents of Pb, Cd, Zn and Mn in fine salts were much lower than those of bay salts and remade salts.

Despite progress made in tuberculosis control worldwide, the disease burden and treatment outcome of multidrug-resistant tuberculosis (MDR-TB) patients have remained virtually unchanged. In 2016, the World Health Organization released new guidelines for the management of MDR-TB. The guidelines are intended to improve detection rate and treatment outcome for MDR-TB through novel, rapid molecular testing and shorter treatment regimens. Key changes include the introduction of a new, shorter MDR-TB treatment regimen, a new classification of medicines and updated recommendations for the conventional MDR-TB regimen. This paper will review these key changes and discuss the potential issues with regard to the implementation of these guidelines in South Korea.

Arsenic (As) is a ubiquitous element found in several forms in foods and water. Although certain foods, such as marine fish, contain substantial levels of organic arsenic forms, they are relatively low in toxicity compared to inorganic forms. in contrast, arsenic in drinking water is predominantly inorganic and highly toxic. Chronic ingestion of arsenic-contaminated drinking water is therefore the major pathway posing potential risk to human hearth. since the early 1990s in Bangladesh ozone, arsenic exposure has caused more than 7,000 deaths and uncounted thousands shout symptoms of long-term arsenic poisoning. Significant portion of world populations are exposed to low to moderate levels of arsenic of parts per billion (ppb) to hundreds of ppb. As a consequence, the World Health Organization (WHO) and U.S. environmental health agencies, such as the Environmental Protection Agency (EPA) made arsenic their highest priority. Recently, the WHO, European Union (EU), and US. EPA lowered an acceptable level of 10 ppb for arsenic in drinking water In this article, various health effects of arsenic in drinking water were reviewed and the current status for risk assessment to regulate arsenic in drinking water was discussed.

The World Health Organization and its member states, in 1978, declared that primary health care is a key to attain the goal of Health for All by the goal of Health for All by the yeas 2000. As a member state of WHO, the Republic of Korea has participated in the declaration of ALMA-ATA and committed to put national efforts for devedoping and implementing primary health care approach with the spirit and content of this Declaration. Since 1978, to translate the spirit of the Declaration into realization, Korean goverment has developed a new category of health manpower such as Community Health Practitioners serving people living in remote rural areas and Village Health Workers serving voluntarily their own village, strengthened the function of Health Centers and Health Subcenters through their reorientation and improved the infrastructure by their new construction or renovation. While primary health care is viewed as an essential health care in Korea, there are some circles who follow a narrow definition in referring to the health care at the periphey of a health system, which is erroneous. Considering the PHC is accepted as the best alternative approach to health care to solve problems that modern health systems are facing, we propose the followings as desirable health policy directions that modern health systems are facing, we propose the followings as desirable health policy directions which might translate the persopective into action at the national level after reviewing past and current PHC approach in Korea : 1. To improve the equity through the reduction of gaps between those who have access to health care and those who have not. 2. To reinforce multisectoral approach and intersectoral coordination through the re- establishment of the National Health Council or establishment of equivalent organization at the central level. 3. To stengthen community participation through lacal people's empowerment by leadership training, changing planning process from the top-down approach to bottom-up and giving the priority to human resources rater than technology, 4. To reinforce the Ministries of Health and Social Affairs through upgrading its role and function to Coordinate Ministries which involve human welfare policies, and creating a Division which is in charge of PHC in the Ministry.

Hand hygiene(HH)of the health care personnels(HCPs) was the most effective method to prevent the transmission of healthcare associated infections. This study was conducted to measure and analysis the status of the HH compliance of HCPs. Data were collected by the direct observation methods of the World Health Organizations(WHO) using WHO's HH monitoring tool kits from 25th October to 31th December, 2010. Data were analyzed by descriptive statistics, cross analysis, multiple logistic analysis using the SPSS/PC 21 program. A total of 8,644 opportunities for HH were observed, and the overall HH compliance rate was 94.1%. HH rates of physicians was lowest(83.4%; OR: 0.209, 95%CI:0.174-0.252). HH rates were statistically different by the job titles(p<0.001), WHO's 5 moments(p<0.001). HH rates in registered nurses(p=0.003), and medical technicians(p<0.001) were statistically different by the WHO 5Moments. Jobs specific HH strategies and WHO 5Moments should be developed to increase the HH compliances of the HCPs.

After the WHO Growth Standards (WHOGS) was published in 2006, many countries in the world endorsed and adopted the new growth references as a standard measure for the growth of infants and young children. Certainly, the WHOGS has an impact on the global policy about obesity and underweight in children. Such WHOGS innovation has influenced many regional health authorities and academies, which have managed their own growth charts for a long time, in changing their strategies to develop and use regional growth charts. In Korea, along with the tradition to create a national growth chart every decade, we now face a new era of advancing with the WHOGS.

Purpose: Extremely hazardous pesticides are classified as World Health Organization (WHO) hazard class Ia. However, data describing the clinical course of WHO class Ia OP (organophosphate) poisonings in humans are very scarce. Here, we compare the clinical features of patients who ingested hazard class Ia OPs. Methods: This retrospective observational case study included 75 patients with a history of ingesting ethyl p-nitrophenol thio-benzene phosphonate (EPN), phosphamidon, or terbufos. The patients were divided according to the chemical formulation of the ingested OP. Data regarding mortality and the development of complications were collected and compared among groups. Results: There were no differences in the baseline characteristics and severity scores at presentation between the three groups. No fatalities were observed in the terbufos group. The fatality rates in the EPN and phosphamidon groups were 11.8% and 28.6%, respectively. Patients poisoned with EPN developed respiratory failure later than those poisoned with phosphamidon and also tended to require longer mechanical ventilatory support than phosphamidon patients. The main cause of death was pneumonia in the EPN group and hypotensive shock in the phosphamidon group. Death occurred later in the EPN group than in the phosphamidon group. Conclusion: Even though all three drugs are classified as WHO class Ia OPs (extremely hazardous pesticides), their clinical courses and the related causes of death in humans varied. Their treatment protocols and predicted outcomes should therefore also be different based on the chemical formulation of the OP.
