Cortisol levels in plasma are known to be as an indication of reproductive and adrenal status of an animal. In this study it has been examined in relation to the oestrus induction by Progesterone oestrogen therapy in 3rd and 4th parity anoestrus animals. Cortisol was found higher in treated animals and levels raised within 6-12 hrs. after hormone therapy followed by elevation in glucose levels and depletion of total serum proteins. It shows the association of induction, occurrence and expression of oestrus with energy demanding metabolic stress in buffaloes.

Purpose: To analyze risk factors for postmenopausal breast cancer. Methods: The present case-control study included 600 women treated at a cancer center reference hospital in a municipality in the South of Brazil. Results: Totals of 100 patients and 500 control subjects were evaluated. The mean age of the women was $52.5{\pm}11.9$ years; the average was $57.4{\pm}11.8$ years, and the average age of the control subjects was $51.5{\pm}11.7$ years. The risk factors for breast cancer that were considered included an age ${\geq}40$ years, postmenopausal status, a body mass index $(BMI){\geq}30kg/m^2$, and reduced physical activity. Variables like postmenopausal status and an obese BMI were associated with cases of breast cancer. Women who were postmenopausal or obese were 3.80 or 1.80 times more likely to develop breast cancer, respectively, and physically inactive women were 1.72 times more likely to develop breast cancer. Conclusions: Obesity and postmenopausal status are associated with the occurrence of breast cancer in this population. Being over 40 years of age was also a statistically significant factor for postmenopausal women.

There are many long and round shape shores due to terrain characteristics in Daecheong reservoir. Therefore it is indicated different spatial distribution of algae every year since the stream is being regulated by these terrain characteristics and reservoir operation about inflow and outflow discharge. Also oversupply of nutrient salt from tributaries of Daecheong reservoir where pollutants were concentrated generates massive growth of algae and depending on hydrological, reservoir operation condition, those proliferated algae at the stagnant tributaries moves to the mainstream of Daecheong reservoir which could create problems of water quality. In this study, it was analyzed the tendency of algae generation by examining algae occurring status for the last 4 years since 2008, and implemented hydraulic analysis at Daecheong reservoir through numerical tracer simulation by applying 3-dimensional hydrodynamic model, ELCOM. Also it was implemented a quantitative analysis of causal relationship based on the algae generation tendency and hydraulic behavior at Daecheong reservoir. Through numerical tracer simulation in this study, it could be noticed the degree of spread of inflow indicated similar trend to the algae occurring status at Daecheong reservoir and verified the different tendency of algae generation in 2011 unlike previous year caused by the rise of water temperature.

Holstein cows being raised in the Kangweon district were examined on the breeding status and occurrence of reproductive disorder. The results obtained were as follows; 1. The cows above six years old in the alpine area were raised more than those in high level zone and plate zone. 2. A total of 1,350 Holstein cows were examined on the breeding status. They were 71.9% conceived cows, 7.9% of uncertain1$\frac{1}{2}$ regnancy, 7.0 of physiological vacancy and 13.3 of reproductive disorder. 3. The percentage of cows conceived by 1, 2, 3 and more than 4 times of A.I. was 49.9, 29.2, 13.3 and 7.6, respectively. 4. In the nutritional condition of infertile coes, excellent, good, fair and poor were 6.7, 30.2, 34.1 and 29.1, respectively. In the good and fair nutritional condition, the cows of ovarian syndrome were 15.6% of persistent corpus luteum, and 11.7% of follicular cystic ovary and lutein cystic ovary, respectively. 5. Among 179 inferTile cows, distributions of reproductive disorder were 43.0, 39.1, 3.9, 3.9 and 10.1% in ovary, uterus vagina, oviduct and others, respectively. Ovary showed higher percentage than any other reproductive organs. Among the ovarian syndromes, follicular cystic ovary, lutein cystic ovary and persistent corpus luteum were 28.6, 28.6 and 23.4%, respectively. 6. A cow group of six and seven-year old showed the highest percentage(21.0% and 23.3%) among the age groups in infertile cows. In the syndrome of reproductive disorder, catarrhal endometritis, latent endometritis, follicular cystic ovary and lutein cystic ovary were 14.5, 14.0, 12.3 and 12.3%, respectively. 7. Infertile cows with complex syndrome of genital disease was 31.8%.

BACKGROUND/OBJECTIVES: The relationship between food intake and nutritional status has been clearly established. Yet, there are only limited studies on food intake among family members and their nutritional status. The study examined the relationship between intra-household food distribution and coexistence of dual forms of malnutrition (DFM) in the same household. SUBJECTS/METHODS: Households with a malnourished child and overweight mother were categorized as DFM. Intra-household food distribution among family members was reported using ratios, which are a measure of individual intakes as compared to all household member intakes adjusted to RDA. RESULTS: A1,899 families were included in the study. The prevalence of DFM was 29.8% (95%CI 26.5-31.2). Children consumed lower amounts of energy (OR 1.34; 95%CI 1.06-1.69, P = 0.011), carbohydrates (OR 1.2; 95%CI1.03-1.61, P = 0.022), protein (OR 1.3; 95%CI 1.03-1.64, P = 0.026), and fat (OR 1.3; 95%CI 1.05-1.66, P = 0.016) than their mothers and other family members. In contrast, mothers consumed more carbohydrates than children and other family members (OR1.24; 95%CI 1.02-1.51, P = 0.03). CONCLUSIONS: This study is the first to report on the food distribution among family members and its relationship with occurrence of DFM in Indonesia. The results confirm the occurrence of an unequal food distribution between children and mothers, which increases risk of DFM in the household. The results also demonstrate that nutritional education at the household level is important to increase awareness of the impact of DFM.

본 논문에서는 IEEE 802.16 OFDMA 시스템에서 QoS를 제공해 주기 위해서 표준에서 정의해 놓은 서비스 클래스 별 대역폭 할당 기법 중에서 UGS 클래스의 대역폭 할당 기법에서의 문제점을 지적하고 이를 해결하기 위한 알고리즘을 제시한다. 802.16 시스템에서는 다섯 가지 트래픽 클래스를 정의하고 이 중에서 UGS 클래스의 서비스 우선 순위를 가장 높게 처리하고 있다. 하지만, 기존의 UGS 클래스를 위한 대역폭 할당 방식에서는 다수개의 UGS 클래스가 존재할 때의 대역폭 할당 주기가 겹치는 문제에 대한 고려를 하고 있지 않다. 이로 인해서 오히려 UGS 클래스의 QoS 서비스를 제공해 줄 수 없는 상황이 발생하게 된다. 본 논문에서는 이런 문제점의 발생을 성능측정을 통해서 보여 주고 이를 해결하기 위한 알고리즘을 제시한다. 또한, 성능 비교를 통해서 제안하는 알고리즘 적용 시에 성능 향상이 있음을 보여 주고자 한다. 본 알고리즘의 적용을 통해서 실제 시스템 적용 시에 발생할 수 있는 문제점을 해결함으로써 보다 안정적인 QoS 서비스를 제공할 수 있는 802.16 시스템이 되리라 기대한다.

Background: The goal of this study was to compare the rate of recurrence and occurrence of complications in colorectal cancer patients after two kinds of laparoscopy and laparotomy. Materials and Methods: A follow-up study was carried out among 358 patients who suffered from colorectal cancer from 2012-2014. The data were gathered from colorectal research center in Shiraz, Shahid Faghihi hospital, and analyzed using the chi-square test, logistic regression, and multinomial regression. Results: The average age of these patients was $56.3{\pm}14.6$, 55.0% being men. Moreover, 57.8% of them underwent laparoscopy surgery and 42.2% of the patients underwent laparotomysurgery and the conversion rate was 58.0% which ultimately was put under the category of laparotomy surgery. After biennial median follow-up, differences in the occurrence of complications such as bleeding (hemorrhage), fever, intestine blockage and wound infection in these two kinds of surgery werestatistically significant (P<0.05). However, the rate of recurrence and the patients' ultimate status (alive without disease, alive with disease, and death) did not significantly differ between these two surgery groups. Conclusions: Post-operation complications were laparoscopy surgery were less than those in laparotomy. However, the outcomes such as patients' ultimate status and recurrence were similar between the two groups.
