This study was carried out in order to find out better ways for superovuiation and egg collection by checking some factors affecting on donor cows such as iactating and dried, age, season of treatment and sequence of treatment. The results were summarized as follows:1. Number of corpus luteum and collected eggs of eactating and dried doner were 9.8 vs 8.0 and 9.6 vs 7.9,respectively. However, the rate of transferable embryos of lactating doner were higher than that of dried, 82.5% vs 48.1%. 2. The average number of corpus luteum and collected eggs of lactating donors under 7 years of age (6.7 vs lactating 5.3) were slightly lower than those of over 8 years of age (11.1 vs 9.2). But the rate of transferable embryoswas better in under 7 years old donors than over 8 years (81.1% vs 49.3%). were 6.0, 4.8, 1.5, 1.8 and 75%, and those in the summer were 2.9, 3.8, 2.2 and 46.7%, respectively. 3. The average number of corpus luteum was the highest in winter (10.5) and the rate of egg collection was the best in autumn (94.7%). The rate of the transferable embryo was the highest in winter (64.3%). 4. The average number of corpus luteum was the lowest (5.5) in the animals treated six or more superovulating treatments. The rate of egg collection was the best in the third treatment group (90.2%), but it was getting worse after fifth treatment, The rate of transferable embryos was the highest in the second treatment group (94.1%), and it was decreased thereafter.
In 2008, according to Statistics Korea's population over the age of 20 and 26.3% of the smokers, 73.7% were non-smokers, smokers and non-smokers by smoking of 22.0% was reported. 336 people of 255 people (75.9%) is currently also showed that smoking. Hypertension, 48 people(14.30%), the boundary type of high blood pressure 193 people (57.40%) of them, especially for high blood pressure appear as a systematic management is required. 336 people targeting taxi drivers smoking and blood pressure, and the relevance of the reserch results did not show a statistically significant difference. Current smokers of 336 people surveyed 255 people (75.90%), respectively. Men over 15 years old in Korea smoking population (1990) was reported as 73.2%, Lee 2001, according etc. Korea 61.8% of the adult male smoking rate is quite high as compared to what is reported. Taxi drivers are working in very bad working conditions. The health of a taxi driver affect the safety of customers were considered.

Epifluorescence microscopy and direct viable counting methods have shown that only 0.01-0.1% of all the microbial cells from marine environments form colonies on standard agar plates. To culture novel marine microorganisms, high throughput culturing (HTC) techniques were developed to isolate cells in very low nutrient media. This approaches was designed to address microbial metabolic precesses that occur at natural substrate concentrations and cell densities, which are typically about three orders of magnitude less than in common laboratory media. Approximately 5000 cultures of pelagic marine bacteria were examined over the course of 3 years. Up to 14% of cells from coastal seawater were cultured using this method, a number that is 1400 to 140-fold higher than obtained by traditional microbiological culturing techniques. Among the cultured organisms are many unique phylogenetic lineages that have been named as new phyla (7), orders (2, 5, 12), families (3), and genera (1, 4, 6). Over 90% of the cells recovered by this method do not replicate in standard agar plating, the most common method of microbial cell cultivation.
The clinical observations on the bronchogenic cancer of one hundred sixty cases treated in the Department of Thoracic Surgery, Seoul National University Hospital are as follows: 1] Most of them,. 90 percent of the cases were over 40 years of age and male was predominated over female with sex ratio of 6 to 1. 2] The average duration of symptoms before the first examination was about 5 months arid the most common complaints were cough, chest pain, breathing difficulty and blood-tinged sputum. 3] In ninety-four cases[59%] thoracotomy was undertaken with resection of the lesion in 52 cases[33% ]. 4] Histopathological diagnoses made in 141 cases were squamous cell carcinoma in 47.5%, undifferentiated cell carcinoma in 33.3%, adenocarcinoma in 9.2,% and alveolar cell carcinoma in a single case.
This study presents a change-point in the 30 years (1976-2005) time series of the annual and the heavy precipitation characteristics (amount, days and intensity) averaged over South Korea using Bayesian approach. The criterion for the heavy precipitation used in this study is 80 mm/day. Using non-informative priors, the exact Bayes estimators of parameters and unknown change-point are obtained. Also, the posterior probability and 90% highest posterior density credible intervals for the mean differences between before and after the change-point are examined. The results show that a single change-point in the precipitation intensity and the heavy precipitation characteristics has occurred around 1996. As the results, the precipitation intensity and heavy precipitation characteristics have clearly increased after the change-point. However, the annual precipitation amount and days show a statistically insignificant single change-point model. These results are consistent with earlier works based on a simple linear regression model.
The city of Sumqayit in Azerbaijan was famous in the USSR for its chemical plants, which supplied the whole country with plastics, detergents, and fertilizers. While production increased in the post-WWII period, young people from remote Caucasian villages were attracted as workers to the industrial settlement on the shore of the Caspian Sea and worked together with specialists from all over the USSR. Migration did not stop when the USSR collapsed. To the contrary, mobility increased as Azerbaijani refugees from Armenia and IDPs from Karabakh fled to Sumqayit, which grew to become the second-largest city of Azerbaijan. Although a generation has passed since the ceasefire, IDPs still are separately administered. In the last 20 years, more and more internal migrants have chosen the Greater Baku Region as their destination, mostly finding jobs in the informal labor market. In the post-independence transformative period, informal housing has offered migrants a place to stay in the city. Sumqayit can be regarded as an arrival city, an established urban platform for migrants who prefer internal over transnational migration.
The purpose of this study is to find out the educational needs for the coronary heart disease patients of a general hospital in a municipal general hospital. The study subjects were 90 outpatients who had been diagnosed as myocardial infection or angina at the hospital from January 3, 1998 to January 31, 1998. The questionaire was consisted of risk factors and educational needs for coronary heart disease patients. The qusetions on the education needs of the coronary heart disease were consist of 34 questions in 6 fields. In analyzing the data, the number and the percentage were calculated in patients general characteristics, the average and the standard-deviation were calculated to understand the educational needs, t-test and ANOVA were used to find out inter group difference on educational needs. In ANOVA, the advanced analysis was done by Scheffe-test. The results of this study were as follows: 1. 52(57.8%) of the patients (90%) live in Kangnung-city and 95% of the patients live in the middle-east part of Korea. At the age distribution 39 to 80, 41.1% of the patients were in their sixties and average age was 62.4 years old. 40% of the patients left school in mid-course or graduated from middle school or high school 2. As a result of the study on the risk factors of the coronary heart disease, the patients who have hypertension and diabetes were 41.1% and 20% respectively. In smoking and drinking, smokers were 30% and drinkers were 40% and average of smoking and drinking duration over 30 years old. 47.8% were over 140mgHg systolic - BP and 45.8% were over 90mmHg diastolic - BP 3. The patients' educational needs average 94.88 (maximum 134), and item average 2.79(maximum 4.0), the highest needs field was the characteristic of disease 33.22(maximum 44). Item average 3.02 (maximum 4.0) and the lowest education needs field was the physical activity and exercise 10.21(maximum 16). Item average 2.55(maximum 4.0) 4. General characteristics which were different from the general characteristic educational needs were statistically different by group of educational level, occupation, age and sex. 5. The risk factors which were different from the coronary heart disease patients' risk factors educational needs were statistically different by groups of the heart disease patients in family and the patients who take regular exercise. with a result the nurses need to improve the educational programs while considering the high educational needs field and the characteristics which showed significant concerns statistically.
The Korea Convergence Society. The aim of this study was to evaluate the association between alcohol consumption and periodontal diseases in Korea adults. The date from the 2014 Korean National Health and Nutrition Survey were used, and 4,328 subjects over 30 years were included in the analysis. Periodontal disease was assessed using the Community Periodontal Index. The adjusted odds ratio of drinking experience, drinking frequency, the drinking amount and the drinking duration were calculated from the logistic regression model with the never-drinkers as a reference group and the logistic model controlled for age, gender, education, and diabetes. This study found that the risk of periodontal disease according to the drinking status of adults over 30 years of age was 1.39 times (95% CI=1.01-1.90) higher than that of non-drinking group when the number of drinks consumed at one time was more than seven glasses. The frequency of binge alcohol consumption, amount of alcohol consumption and duration of alcohol consumption were significantly associated with the risk of periodontal disease in a dose-response pattern among over 30 years. Alcohol consumption was discovered to be a potential risk indicator for periodontitis. Dental practitioners need to be aware that patients who drink may be at higher risk of periodontitis and could benefit from advice to quit drinking and maintain regular dental visits.
The population ecology (Ecological characteristics) of Squalidus chankaensis tsuchigae were investigated at Geum River from March to November, 2013. This species inhabited midstream of the river where was mostly covered with cobble and sand. The depth of the habitat was 30~60 cm and velocity of stream was 2.27~4.88 cm/sec. The sex ratio of female to male was 1 : 0.86. They were sexually mature when they were over two years of age. The spawning period was from June to July with water temperatures from $25^{\circ}C$ to $25^{\circ}C$. Sexually matured individuals appeared over the two year of age. Frequency analysis of total length indicated that the group with 55~70 mm in total length was one year old, the 71~90 mm was two years old, and the group over 91 mm was three years old. The average number of eggs in the ovaries was estimated as 2,219 per matured female. The number of matured eggs size in ovaries was 0.64~0.98 (mean: 0.85) mm. Calulation length-weight relation of S. chankaensis tsuchigae show the value of contant a as 0.0002 and b as 2.81, and condition factor (K) was 1.06 on average. The stomach contents were Cyanophyta, Chlorophyta, Bacillariophyta, Crustaceae, Copepoda, Nematota, Actithocephala, and Ephemeroptera, Hemiptera, Diptera, and Trichoptera that belong to Aquatic insect, and dormant bud of Pectinatella that belongs to Phylactolaemata. The diet of S. chankaensis tsuchigae was omnivorous, mainly vegetable feed on attached algae (filament form), and mainly animality feeded on benthic invertebrates such as Chironomidae larvae.
The dietary patterns and characteristics of oldest-old subjects over 85 of Sunchang County (total of 171, 61 males and 110 females) were studied. The average age was $90.6{\pm}3.7$ years old (male; $89.1{\pm}2.8$, female; $91.5{\pm}3.8$), and 90.9% of them were reported to have had no schooling experience. Family types having a spouse were much greater in men (50%) than women (1.8%). The percentages of living alone showed the gender differences, which were comprised of 33% of females and 18.3% of males. In this study, 73.7% of subjects answered "very good" or "good" for their health status. These elderly subjects might maintain their health through a relatively lower rate of smoking (22.2%) and drinking (27.5%), having non-sedentary activities (84.2% of the subjects are physically active) and enough sleep. Their characteristic dietary patterns include high preference of rice (96.5%) and blanch & Seasoned vegetable dishes (Namal, 90.6%) frequent consumption of plant-based food groups containing plenty of anti-oxidants such as vegetables and legumes, and they showed high rates of meal regularity (77.2%) and no skipping of meals (94.2%). It seems to be developed and disseminated in the congregate meal program for improving nutritional status of the elderly, since the coming increment of single-elderly family and single dwellers of rural areas.
