Objectives : This paper examines the effects of Particulate Matter on human bodies and the possibility of treating them with Chinese or Korean medicines. Methods : This paper categorizes the diseases caused by Particulate Matter, as well as the causes, pathology, prevention methods, and effectiveness of treatments by Chinese and Korean medicines. Based on these results, it analyzes whether such diseases can be managed by Chinese and Korean medicine. Results : Particulate Matter is known to affect respiratory organs, skin, circulatory system, nervous system, gestational diabetes, and other parts of the human body. While studies show evidence that treatments by Chinese and Korean medicines can reduce symptoms of some diseases and improve bodily functions that are damaged by Particulate Matter, there is no statistically significant evidence that they can provide fundamental treatments nor treat irreversible damages. Conclusion : Currently, there is no definite evidence that Chinese and Korean medicine can treat symptoms and diseases caused by Particulate Matter. Therefore, some Korean medicine doctors' arguments that Korean medicine is effective in treating such diseases are problematic, and thus, there is a need for much research in this field.

Purpose: The purpose of this study was to examine the trends of disease of residents who had treatment in primary health care posts in N-county over the past seven years (1997-2003). The data will assist in planning responses to changes in the health care environment and in planning health promotion programs. Method: A retrospective descriptive survey was conducted of the computerized records of primary health care done by community health practitioners over the last seven years. Cross analysis was conducted among the data using SAS, and the results were displayed in frequencies and percentages. The data were collected from May to September 2004. Results: The results of the study are as follows: 1. The six most frequent diseases were ranked as follows: diseases of the 1) respiratory system, 2) musculoskeletal system and connective tissue, 3) digestive system, 4) skin and subcutaneous tissue, 5) circulatory system, and 6) symptoms, signs and abnormal clinical and laboratory findings. Especially in 2002, circulatory system related disease rose two steps in the ranking and digestive system related disease went a step down. 2. The patients' use of primary health care posts over the past seven years continued to increase on the whole. Conclusions: According to these results, each primary health care post should carry out special health promotion programs that fit the local society of N- county and are in accordance with changes in health care needs.

Dogs exhibit patterns of health issues that vary by life stage. An understanding of disease incidence with respect to breed and age/life stage could be an important component of canine health management and welfare. This study aimed to describe the age-specific disease incidence of 3 small dog breeds that attended veterinary clinics in the Republic of Korea, based on data from electronic veterinary medical records (EVMRs). A total of 40,785 EVMRs from Maltese (n = 21,355), Miniature Poodle (n = 11,658) and Shih Tzu dogs (n = 7,772) were analyzed. Common health problems in 3 small dog breeds were 'diseases of the skin' and 'diseases of the ear,' respectively. Among dogs aged ≤ 3 years, 'preventive medicine' was the most common cause cited for veterinary clinic visits. Among dogs aged 4 to 8 years, the most frequent health problems were 'diseases of the skin.' Among dogs aged 9 to 13 years, 'heart diseases,' 'kidney diseases,' 'mammary gland tumor,' and 'neoplasia (unspecified)' were considerably more frequent, compared to the rates in dogs ≤3 years. Among dogs aged ≥ 14 years, 'heart diseases' and 'sneezing/cough' were the main health problems. In all breeds, the frequencies of 'diseases of circulatory system,' 'diseases of respiratory system,' 'diseases of the nervous system,' 'endocrine' and 'neoplasia' increased rapidly with aging. This surveillance could inform strategies for disease screening tests and management based on life stage in these dog breeds and enable more effective health management.

This study was carried out to calculate working life expectancy and its potential gains according to the degree of reduction in the specific causes of death. It sought to ascertain what potential gains in labor force longevity might be reasonably achieved through efforts to reduce mortality from injuries and poisoning, diseases of circulatory system, neoplasms and the other causes of death. The data were drawn from the three sources such as "The 1982 Causes of Death Statistics," "Abridged Life Table for Korea 1978~'79" and "The 1982 annual Report of Economically Active Population" issued by Economic Planning Board. Analytical tools used in this study were the cause-deleted life table and the Wolfbein Wool's working life table method. Partial life expectancy was adopted as an index of this study, This application will be widely used as a good demographic tool for analyzing the dynamics of labor force and causes of death. Some of the findings are summerized as follows. 1. Partial life expectancies from initial age 15, 25, and 45 respectively to terminal age 65 are 44.86, 35.59 and 17.41 year in life expectancy itself, 37.08, 32.83 and 15.21 year in working life expectancy, 7.78, 2.76 and 2.20 years in inactive life years. 2. Potential gains in working expectancy from initial age 15, 25 and 45 to terminal age 65 by the complete elimination of the specific causes of death are 1.36, 0.94 and 0.27 years in injuries and poisoning, 0.88, 0.83 and 0.54 years in diseases of circulatory system, 0.56, 0.54 and 0.37 years in neoplasms, 1.13, 1.02 and 0.58 years in the other causes of death. The relationship between degree of reduction in causes of death and potential gains in working life years is in direct proportion. The prime orders of reduction effectiveness in age groups by the causes of death are injuries and poisoning in age 15-24, the other causes of death in age 25-49 and diseases of circulatory system in age 50 and over. 3. If it were possible to reduce 25%, 50% and 75% in mortality condition 1978~'79, the average length of working life would be 38.08, 39.13 and 40.17 years in age 15, and 33.68, 34.57 and 35.44 years in age 25, and 15.67, 16.14 and 16.63 years in age 45.

To diagnose vascular diseases from the viewpoint of hemodynamics, detailed quantitative hemodynamic information of related blood flows with a high spatial resolution of tens micrometer and a high temporal resolution in the order of millisecond were required. For investigating the hemodynamic phenomena of vascular circulatory diseases, a new diagnosing technique combining a medical radiography and PIV method was newly developed. This technique consisted of a medical X-ray tube, an X-ray CCD camera, a shutter module for double pulse-type X-ray source, and a synchronizer. Through several preliminary tests, the feasibility of the angiographic PIV technique was verified. For in-vivo measurements to real blood flows, we developed tracer microcapsules which were optimized to this system by encapsulating a contrast material of iodine with a matrix material of PVA (polyvinylpyrrolidone). In near future, the angiographic PIV technique would be useful for diagnosing hemodynamic phenomena of vascular diseases and for their early detection.

To diagnose circulatory diseases in the viewpoint of hemodynamics, we need to get quantitative hemodynamic information of blood flows related with the vascular diseases with high spatial resolution of tens micrometer and high temporal resolution in the order of millisecond. For investigating in-vivo hemodynamic phenomena, a new diagnosing technique combining medical radiography and PIV method was newly proposed and developed. This angiographic PIV technique consists of a medical X-ray tube, an X-ray CCD camera, a shutter module for double pulses of X-ray, and a synchronizer. The feasibility of the angiographic PIV technique was tested and quantitative flow velocity field distribution of a flow inside an opaque conduit was acquired by the developed system. It can be used for measuring flow phenomena of nontransparent fluids inside opaque conduits.

Objectives : This study was performed to investigate the characteristics and ADL(Activities of Daily Living) associated factors of elderly inpatients in long-term care hospitals. Methods : Data were collected from the nationwide data of 'Survey of Patients (2013-2014)' administerd by the Ministry of Health & Welfare. The data included in this study consisted of 27,606 cases of elderly inpatients in long-term care hospitals. Results : The survey scores for the elderly inpatients were as follows: 57.6% 'Needed much and total help' with ADL, followed by 26.6% who 'Needed much help', and 15.8% who 'needed minimal supervision' in long-term care hospitals. The ADL score was high in the following categories: women, old age, referred visit, health insurance type, not-recovered & death, transferred, corporate hospitals, small hospital size, low number of physicians per 100 beds, and high number of nursing staff per 100 beds. The inpatients with 'diseases of the nervous system', 'diseases of the circulatory system' and 'diseases of the genitourinary system' were more likely to have high ADL scores. Conclusions : The results of this study suggest that long-term care hospitals should provide active and proper care for patients with high ADL scores and improve medical personnel training as well provide more medical care.

Regenerative medicine is a research field that develops methods to restore damaged cell or tissue function by regeneration, repair or replacement. Stem cells are the raw material of the body that is ultimately used from the point of view of regenerative medicine, and stem cell therapy uses cells themselves or their derivatives to promote responses to diseases and dysfunctions, the ultimate goal of regenerative medicine. Stem cell-derived extracellular vesicles (EVs) are recognized as an attractive source because they can enrich exogenous microRNAs (miRNAs) by targeting pathological recipient cells for disease therapy and can overcome the obstacles faced by current cell therapy agents. However, there are some limitations that need to be addressed before using miRNA-enriched EVs derived from stem cells for multiplexed therapeutic targeting in many diseases. Here, we review various roles on miRNA-based stem cell EVs that can induce effective and stable functional improvement of stem cell-derived EVs. In addition, we introduce and review the implications of several miRNA-enriched EV therapies improved by multiplexed targeting in diseases involving the circulatory system and nervous system. This systemic review may offer potential roles for stem cell-derived therapeutics with multiplexed targeting.
