To monitor the reproductive patterns of endangered common chimpanzee including annual reproductive cycle, amenorrhea, breeding season, and pregnancy diagnosis, Time-Resolved Fluorescence Immuno Assay (TR-FIA) was used to trace MRH (estradiol, progesterone, testosterone) and human chorionic gonadotropin (HCG). In result of this research, age was not the important factor in determining the reproduction capability in common chimpanzee; it was rather greatly influenced by the combination of various factors such as individual's fertilizing ability, presence of obstetrical diseases, the pattern of mating behavior, and the mental communication under the introduction of a mating partner. This research will play an important role in operating conservation project for common chimpanzees and can be extended also for shedding new light on understanding human menopause and obstetrical diseases.

We have studies in 38 subjects (19 control and 19 experiment) for development of functional food for postpartum body control. Mean age of control and experimental subjects were each other 30.4 and 29.0 years old, and mean body mass index were 20.2 and 21.4. Total weight gain during pregnancy of control and experimental subjects were 14.0kg and 19.8kg. We measured change of weight and liver activity after parturition for 3 months. It shows that weight not reduced until 30 days in postpartum but significantly decreased during 30 days to 90 days. The mean weight of control and experimental subjects were decreased 3.15kg and 6.46kg at 60 days(p<0.05), 4.47kg and 7.44kg at 90 days(p<0.05). In this study, hemoglobin, GOT and CPT level were not changes before and after of experiment, respectively.

Unexpected antibody screening and identification tests are highly important in the prevention of hemolytic transfusion reactions. Therefore, it is highly recommended to perform unexpected antibody screening test in all transfusion candidates. Here, the frequency and distribution of unexpected antibodies identified in Jeju for the past 3 years were evaluated. Between Jan 2014 and Dec 2016, unexpected antibody screening test was performed for 10,360 sera of transfusion candidates in Jeju general hospital using a column agglutination method with the Ortho BioVue system (Ortho-clinical Diagnostics, Raritan, NJ, USA). Eighty-seven (0.84%) of 10,360 cases that underwent unexpected antibiotics screening showed positive results. Among them, unexpected antibodies were identified in 41 cases (0.40%). Unidentified antibodies were detected in 8 cases (19.51%) and autoantibodies were detected in 3 cases (7.32%). The anti-E antibody included in warm antibodies were detected most frequently in 8 cases (19.51%); 6 cases (14.63%) of anti-E + anti-c antibody and 3 cases (7.32%) of $anti-Le^a+anti-Le^b$. $Anti-Le^a$ and $anti-Le^b$ antibodies were detected in 2 cases (4.88%), respectively. The anti-D, $anti-Di^a$, $anti-Fy^b$, $anti-Jk^a$, $anti-Jk^b$, anti-M and anti-P1 were detected in 1 case (2.44%). Complex antibodies were detected in 1 case (2.44%) in anti-C+anti-D and anti-E+anti-c+$anti-Jk^b$, respectively. In this study, we analyzed the frequency and distribution of unexpected antibodies in one general hospital for the past 3 years. However, there has been a general increase in multicultural families and foreign workers in Jeju, and it would be a meaningful study to compare the frequency and distribution of unexpected antibodies.

The purpose of this study is to investigate factors related to substance use focusing on the sexual experiences and risky sexual behaviors among Korean adolescents. This study conducted with a secondary data analysis using the Seventh Korea Youth Risk Behavior Web-based Survey 2011 in South Korea. The study participants selected 75,643 Korean adolescents who were recruited anonymously through national web-based survey. Data were analyzed using descriptive statistics, rao-Scott ${\chi}^2$, and logistic regressions considering complex samples. Results indicated that substance use was significantly associated with sexual experiences such as sexual intercourse with the opposite sex (adjusted OR=5.691; 95% CI=4.223-7.670), sexual intercourse with the same sex (adjusted OR=21.180; 95% CI=14.704-30.507) and risky sexual behaviors such as sexual assaults (adjusted OR=9.936; 95% CI=7.217-13.680), date rape (adjusted OR=16.979; 95% CI=11.648-24.751), sexual intercourse after drinking (adjusted OR=6.564; 95% CI=3.986-10.810), unexpected pregnancies (adjusted OR=18.628; 95% CI=8.476-40.936), and sexually transmitted diseases (adjusted OR=21.872; 95% CI=13.920-34.367) in Korean adolescents. Findings of this study show that adolescents who use substances are more likely to engage in risky sexual behaviors. Therefore, intervention program should be designed to consider both substance use and sexual problems and to include the effective approaches at the family and school level.

Animal models can provide a useful tool for the study of some aspects of psychiatric disorders and their treatment. The four criteria for the evaluation of animal models of psychiatric disorders are as following : 1) similarity of inducing conditions 2) similarity of behavioral state 3) common underlying neurobiological mechanisms 4) reversal by clinically effective treatment techniques. Several animal models have been proposed for schizophrenia : phenylethylamine model, L-dopa model, hallucinogen model, cocaine model, amphetamine model, phencyclidine model, noradrenergic reward system lesion model, reticular stimulation model, social isolation model, conditioned avoidance reaction, catalepsy test, paw test, self-stimulation paradigms, latent inhibition paradigms, blocking paradigms, prepulse inhibition of the startle reflex, rodent interaction, social behavior in monkeys, hippocampal damage, high ambient pressure, and models using selective breeding. Among them, animals with bilateral lesion of the hippocampus may provide an adequate animal model for several symptoms of schizophrenia, and ketamine model can reproduce negative symptoms and cognitive deficits as well as positive symptoms of schizophrenia. In conclusion, no model of schizophrenia is entirely representative of the disease, and findings gleaned from model systems must be cautiously interpreted. Furthermore, the process of developing and validating animal models must work in concert with the process to identify reliable measures of human phenomenology.

Breathing is the voice's driving force and also acts as a regulator of larynx function and efficiency. Respiratory distress is a side effect of general anesthesia in thyroid surgery. Therefore, this study's objective was to provide practical and complementary information for voice recovery after thyroid surgery, based on aerodynamic evaluation pre- and post-thyroidectomy. From May 2014 to July 2015, aerodynamic evaluations were performed on 34 female patients diagnosed with thyroid papillary cancer one week before surgery (PRE), one month after surgery (P1), and three months after surgery (P3). The Phonatory Aerodynamic System (model 6600, KayPENTAX, USA) was employed for this purpose, and a total of 29 analysis parameters were selected. The results showed statistically significant differences in peak expiratory airflow (p=0.004), mean pitch (p<0.01), expiration airflow duration (p=0.001), and expiratory volume (p=0.018), based on time factors. In the comparison of time factors, peak expiratory airflow and mean pitch parameters were different in PRE-P1 and PRE-P3. Expiration airflow duration and expiratory volume parameters were different in PRE-P3 and P1-P3. The interaction effect of time and surgical range was significant only for expiratory volume (p=0.024). Female patients who undergo thyroidectomy require post-operative breathing training, and exhalation improvement is considered to reflect a positive lifestyle after surgery.

Today, as the specification of pigs increases, it is important to develop eco-friendly livestock feeds that do not add antibiotics to highly utilizable materials as feed resources, and to produce functional eco-friendly pork and processed products. The purpose of this study was to establish Rubus occidentalis (RO) byproducts containing various amounts of physiologically active substances such as anticancer, anti - inflammation and antioxidant as a raw material for pig feed. The multifaceted efficacy of the RO fermented fodder (ROFF) was confirmed by the nutrient transport factors and antioxidant activity of Berkshire pigs. ROFF was added 0.3% to the general diet and the efficacy was confirmed by feeding diets to Berkshire pigs according to each weight for 43~73 days. As a result, the total cholesterol (TC), LDL-cholesterol (LDL-C) and HDL-cholesterol (HDL-C) levels were decreased or were increased in the castrated male and female Berkshire pigs but not significantly. It was confirmed that the tendency was improved in nutrition physiology. The biochemical levels of female finishing pigs were not significant but increased. In the case of finishing pigs with possibility of pregnancy, it is expected that the nutrition supply for piglet production and will help in the production of the healthy piglet. Transferrin (TFE) levels tended to increase in female growing pig and 110-150 kg finishing pigs. Thus ROFF could minimize the negative effects of iron contents deficiency in female Berkshire pigs. Glutathione peroxidase 1 (GPx1) activity was increased in castrated male and female 110-150 kg finishing pigs. Therefore, ROFF tends to improve the antioxidant capacity. The results of this study suggest that ROFF is one of the most favorable dietary sources when considering the contents of RO in feed. In particular, ROFF could have a positive effect on nutrient transport and iron content of female rather than castrated male Berkshire pigs.
