Gastritis is a major disease that has the potential to grow as gastric cancer. Gastric cancer is a very common cancer, and it is related to a very high mortality rate in Korea. This disease is known to have various reasons, including infection with Helicobacter pylori, dietary habits, tobacco, and alcohol. The incidence rate of gastritis has reported to differ between age, population, and gender. However, unlike other factors, there has been no analysis based on gender. So, we examined the high risk factors of gastritis in each gender in the Korean population by focusing on sex. We performed an analysis of 120 clinical characteristics and genome-wide association studies (GWAS) using 349,184 single-nucleotide polymorphisms from the results of Anseong and Ansan cohort study in the Korea Association Resource (KARE) project. As the result, we could not prove a strong relation with these factors and gastritis or gastric ulcer in the GWAS. However, we confirmed several already-known risk factors and also found some differences of clinical characteristics in each gender using logistic regression. As a result of the logistic regression, a relation with hyperlipidemia, coronary artery disease, myocardial infarction, hyperlipidemia therapy, hypotensive or antihypotensive drug, diastolic blood pressure, and gastritis was seen in males; the results of this study suggest that vascular disease has a potential association with gastritis in males.

Purpose: To identify the essential characteristics of pain which nurse have to obtain for patients with chest pain, 92 patients who were admitted in medical units to take intensive tests for heart disease were investigated cross-sectionally. Method: Duration, severity, stress, anxiety, perceived severity, number of painful area, number of accompanying symptoms, triggering activity, and pattern were included as the characteristics of pain. Ejection fraction of left ventricle and number of involved area detected by ultrasonography and number of diseased coronary artery detected by cardiac catheterization were assessed as the variables of heart disease extent. Result: Severity of pain was found to be correlated with all three variables of heart disease extent. Perceived severity and number of accompanying symptoms were correlated with two of them. Anxiety, number of painful area and pattern were related with the number of involved area. Conclusion: Pain severity reported by patients is found to be the most important variable to be obtained from patient. Variables such as perceived severity, number of accompanying symptoms, anxiety, number of painful area and pattern also have to be carefully assessed to anticipate the extent of heart disease.

The voice of aged persons is known generally to be somewhat different from that of other adults, suggesting that laryngeal change occurs with advancing age. However, because knowledge of the voice characteristics of aged persons is limited, it is difficult to judge whether their voices arc normal. Chart review and laryngoscopic examination from ninety-one patients with hoarseness over the age of 60(1st group) and one hundred sixteen patients with hoarseness below the age of 50(2nd group) were done to define aging related voice disorders. The following results were obtained. 1) Associated diseases related to laryngeal disease were hypertension(12%), pulmonary disease(4.4%), thyroid disease(1.1%) in 1st group and hypertension(9.5%), thyroid disease(1.7%) in 2nd group. 2) The underlying diseases causing hoarseness in order of frequency were benign vocal fold lesion(37.7%), inflammatory disease(36.8%), functional dysphonia(17%) in 1st group and benign vocal fold lesion(43.6%), functional dysphonia(26.3%), inflammatory disease(16.5%) in 2nd group. 3) In stroboscopic findings, atrophy and sulcus of vocal cords are more prevalent in males than in females and edema of vocal cords is more common in females. Generally the voice characteristics of aged persons depend on the mass of the vocal folds which may be decreased through atrophy or be increased by edema. However, other factors such as systemic diseases, drug side effects and compensatory mechanism to presbylaryngis must be taken into account in diagnosing and treating voice disorders in aged persons.

The survey was conducted to investigate several factors affecting the disease outcome with 116 infants aged 10 to 24 months residing in Kunsan city, Cheonbuk province . General characteristics, weaning practice , nutrient intake and the actual state for affecting disease were studied. Among many factors, mother's educational status was found to be the most influencing factor for affecting the disease outcome analyzed by oneway ANOVA. The exposure index disease, cold and diarrrhea, against mother's education were analyzed to find out the major factors for disease outcome. The education group up to middle school graduates, mother's job , nutrients supplements, feeding method, sex of baby were the factors, for the high school graduates, job , nutrients supplements were the causes, and the group graduated from the college the above grade mother's health state was the most important factor for the baby exposing to the disease. The disease outcome decreased when the bottle feeding was replaced by breast feeding, sufficient nutrients supplementation was recommended , and health care for mother during pregnancy was strongly advised.

Mummy disease has been observed for a long time in the button mushroom, Agaricus bisporus farms in Korea, and severe mummy disease occurred on “Shinryung” mushroom, A. blazei recently. Typical symptoms of mummy disease were observed on the mushroom-cultivation beds infected ; tilted caps of mushrooms, browning and lignified internal tissue of stipe, overdevelopment of mycelium around the base of the stipe, and mummified mushrooms. Electron micrographs prepared from internal tissue of stripe of the diseased mushrooms showed that many bacterial cells present inside hyphal cells of the diseased mushroom, which is one of the characteristics of mummy disease reported previously, Survey in Buyo, Chungnam showed that mummy disease occurred at 55% and 83% frequency on bottom mushroom (brown strain) and “Shinryung” mushroom cultivation during year 2000. It indicates that mummy disease is one of the major diseases for the mushrooms cultivation.

Chronic disease such as rheumatoid arthritis is believed to induce a significant psychosocial stressors. The concept of illness intrusiveness-illness induced life style disruptions-was hypothesized to affect psychosocial status. And demographic, socioeconomic, disease and social characteristics were hypotehsized to affect illness intrusiveness. Hierarchial multiple regression analyses were used. As a result, among the demographic factors gender was identified as contributor to directly increase the psychosocial stress and education level was identified to affect the psychosocial stress through illness intrusiveness. Among socioeconomic factors, the burden about the cost of medical treatment was found to indirectly affect the psychosocial stress through the illness intrusiveness. Also income and job were found to affect directly the psychosocial status. Among the disease characteristics, only the pain level was identified to increase the psychosocial stress through the illness intrusiveness. Among the social characteristics, perceived social support is identified to increase the psychosocial stress through the illness intrusiveness. Based upon these results, some suggestions were made for minimizing illness intrusiveness in rheumatoid arthritis and future research.

During a disease survey on weeds and minor cultivated crops in Korea, a brown leaf spot disease was observed on Sonchus asper. Leaf lesions were round or irregular in shape, and grayish brown to brown with a purple margin. In severe infection, lesions enlarged and coalesced, resulting in blighting of the leaves. The isolates from these leaf lesions were identified as Alternaira sonchi based on morphological characteristics and phylogenetic analyses of Internal transcribed spacer region, Alternaria allergen a1, glyceraldehyde 3-phosphate dehydrogenase, RNA polymerase II, and translation elongation factor genes. This study provides a comprehensive description of the morphological characteristics and phylogenetical traits of A. sonchi causing brown leaf spot on S. asper in Korea.

Wilt symptoms were frequently observed in Korean blackberry (Rubus coreanus) plants grown in farmers' fields located in Gochang and Jeongeup, Jeonbuk Province, Korea during disease surveys in July 2020. The disease occurred in 10 of the 13 fields surveyed in the two locations. The incidence of diseased plants in the fields was 5-80%. Seven isolates of Fusarium sp. were obtained from the diseased plants and examined for their morphological and molecular characteristics. All the isolates belonged to Fusarium oxysporum species complex based on the morphological characteristics but were identified as F. cugenangense based on the molecular characteristics. Two isolates of F. cugenangense were tested for pathogenicity on Korean blackberry plants by artificial inoculation. Pathogenicity of the two isolates on the plants was confirmed with the inoculation tests, which showed wilt symptoms similar to those observed in the diseased plants in the fields investigated. This is the first report of F. cugenangense causing Fusarium wilt in Korean blackberry.

In year of 2013, anthracnose disease symptoms were observed on stem of stonecrop in a plant resource field, Southern Forest Resource Research Center, Jinju, South Korea. The disease symptoms were appeared 2-5 cm smudged irregular black spot color on the plant stems. Suspected pathogen was isolated from the lesion with surface sterilization method and identified it as Colletotrichum gloeosporioides by morphological characteristics and phylogenetic analyses. Artificially inoculated the isolated pathogen led to the similar disease symptom as originally observed in the field. The fungal pathogen was re-isolated from the inoculated lesion and it exhibited the same characteristics compared to the original isolate. This is the first report of anthracnose of stonecrop grown in open fields, caused by Colletotrichum gloeosporioides in Korea.

It is widely accepted that Parkinson's disease(PD) is the most common cause of hypokinetic dysarthria, and its characteristics of 'short rushes of speech' have become more evident along with the severity of motor disorders. Speech alternate motion rates (AMRs) are particularly useful for observing not only rate abnormalities but also deviant speech. However, relatively little is known about the characteristics of 'short rushes of speech' in terms of AMRs of PD except for the perceptual characteristics. The purpose of this study was to examine which acoustic features of 'short rushes of speech' in terms of AMRs are a robust indicator of Parkinsonian speech. Numbers of syllabic repetitions (/pə/, /tə/, /kə/) in AMR tasks were analyzed through acoustic methods observing a spectrogram of the Computerized Speech Lab in 9 patients with PD. Acoustically, we found three characteristics of 'short rushes of speech': 1) Vocalized consonants without closure duration(VC) 76.3%; 2) No consonant segmentation(NC) 18.6%; 3) No vowel formant frequency(NV) 5.1%. Based on these results, 'short rushes of speech' may affect the failure to reach and maintain the phonatory targets. In order to best achieve the therapeutic goals, and to make the treatment most efficacious, it is important to incorporate training methods which are based on both phonation and articulation.
