Although Bi(脾 Spleen) is a major organ which controls digestion and absorption in Korean medicine, there also introduced another function of bi, which is called 'bitonghyul(脾統血)' that means the spleen controls(holdings) the blood. While the spleen is involved in the function of blood generation through the digestion and absorption of food, 'bitonghyul' is another expression regarding function of the spleen. The meaning of 'bitonghyul' is related with the function of keeping the blood flowing within the blood vessels, hemostasis. Comparing the function of the spleen with the mechanisms of hemostais, it is concluded that 'bitonghyul' is a physiological effects which affect hemostatic mechanisms via absorption of vitamin K.

Burning and lump sensation in the throat is a common disorder in middle aged woman. It is generally considered to be a neurotic origin but its pathophysiology is still remained unknown. The purpose of this study was to evaluate the prevalence of the Pharyngoesophageal structural lesions and the esophageal motility disorders among the patients with globus pharyngeus and to elucidate whether any specific manometric abnormality might have any causative role in the pathogenesis of the globus sensation, and we also wanted to know whether such tests were necessary in evaluating those patients. Structural lesions were demonstrated in 21 cases(17.5 %) among 120 patients. But among 44 controls, there were also Two cases(4.5 %) of structural lesions, and there was less significantly difference in the prevalence of the structural lesions between the patients and controls(p=0.0625) Manometric abnormalities over the lower esophageal sphincter and the lower esophageal body were demonstrated in 28 cases (23.3 %) of the patients, while only one case (2.3 %) of the controls revealed such abnormality ( p=0.0037). Various manometric parameters of the upper esophageal sphincter and pharynx showed no difference between the patients and controls except the upper esophageal sphincter pressure at lateral sides which was lower in patients than in controls (p=0.0034). Globus sensation is a kind of symptom of esophageal dysmotility, and esophageal manometry is necessary to detect such abnormality in patients with globus sensation, Careful physical examination is also necessary to detect structural lesions in the pharynx and esophagus.

Objective:Event-related potentials(ERPs) are electrical changes recorded at the surface of the scalp in response to stimulus presentation, and their latency and amplitude change according to cognitive processes. Through past studies of the auditory ERP in schizophrenia, the P300 has been reported to be statistically smaller and delayed in schizophrenia than comparison groups. However, studies of the visual ERP have not been systematically examined. The present study was designed to investigate the visual P300 in patients with schizophrenia and normal controls and to compare the pattern of P300 between them. Methods:The subjects were composed of patients(N=22) with schizophrenia by DSM-IV and normal controls(N=22). The visual ERPs were measured by the visual continuous performance test. P300 amplitude and latency measured on 5 scalp electrodes(Fz, Cz, Pz, $T_7$, $T_8$) were compared between patients and controls. Results:The P300 latencies measured on Fz, Cz, Pz, and $T_7$ electrodes were significantly longer in patients than controls(p<0.05). The P300 amplitudes in patients were smaller than controls. However, the difference between them was not statistically significant. Conclusion:Analysis of the visual ERPs showed that the P300 latency is significantly delayed and the P300 amplitude is slightly smaller in patients than controls. These results are similar to established studies of the auditory P300 in schizophrenia.

This study was conducted with 20 female gymnasts and 23 age-matched controls to examine the relationship of diet, menstrual function and bone mineral density (BMD). The results obtained are summarized as follows : Energy intake of gymnasts was 968.9$\pm$421.4kcal, and energy expenditure was 2091.4$\pm$361kcal showing negative energy balance(-1,122.5$\pm$534.6kcal). The average intakes of calcium, iron, vitamin A, thiamin, riboflavin and niacin did not meet the Recommended Dietary Allowances for their age groups. Mean age at menarche in gymnasts is 15.8$\pm$1.2 years compared with 11.8$\pm$2.8 years in age-matched controls. The profile of estradiol, progesterone, and luteinizing hormone was lower than age-matched controls but not significant. Athletic amenorrheic gymnasts(n=12) have the menstrual irregularity(n=10) and amenorrhea(n=2). A number of variables as such nutritional deficiency in diet, negative energy blasnce and hypogonadotropic hormonal status were included. The bone mineral density (BMD) of female gymnasts were significantly higher than controls for the lumbar neck(p<0.001), trochanter(p<0.01), and Ward's triangle(p<0.001), but there were no significant differences for the lumbar spine and forearm. The lumbar spine BMD had a positive correlation with age and lean body weight. The femoral neck BMD was significantly associated with age, group and lean body mass. The trochanter BMD had significant relationship with group, body mass index, energy expenditure and follicular stimulating hormone. Ward's triangle BMD were related to body mass index and follicular stimulating hormone. The significant association was deterced between forearm BMD and age and lean body weight. The major finding of this investigation is that the BMD of gymnasts were higher than age-matched controls despite the fact that gymnasts as a group had inadequate dietary calcium and a higher propensity to have an interruption of their menstrual cycle. These data indicate that grymnsts involved in sports producing significant impact loading on the skeleton had greater femoral neck, trochanter and Ward's triangle bone density than age-matched controls.

그 동안 프라이버시 역설 현상을 설명하기 위한 많은 노력에도 불구하고 기존 연구들은 상반된 결과들을 보고하였다. 일부 연구들은 프라이버시 염려와 자기노출 사이의 관련성을 발견한 반면, 다른 연구들은 그렇지 못했다. 본 연구는 SNS 환경에서 이러한 관련성에 영향을 미칠 잠재력이 있는 상황변수로 상호작용 프라이버시 컨트롤(주로 프렌드 리스트와 프라이버시 셋팅)의 역할을 검토한다. 이러한 이유는 사용자들이 상호작용 프라이버시 컨트롤을 사용하여 자신의 사회적 환경을 조성하기 때문에 이것의 사용정도에 따라 프라이버시 염려와 자기노출 사이의 관계가 영향을 받기 때문이다. 본 연구는 서베이 방법을 활용하였고, 위계적 다중회귀분석을 사용하여 상호작용 프라이버시 컨트롤 사용의 조절효과를 분석하였으며, 분석결과 상호작용 프라이버시 컨트롤 사용의 조절효과를 발견하였다. 따라서 상호작용 프라이버시 컨트롤의 사용은 SNS를 대상으로 프라이버시 역설 현상을 검토하는 연구에서 고려해야 하는 중요한 상황변수라고 할 수 있다.

We need to understand the outcomes into adulthood for survivors born either extremely low birthweight (ELBW; <1,000 g) or extremely preterm (EP; <28 weeks' gestational age), particularly their blood pressure and cardiovascular metabolic status,respiratory function, growth, psychological and mental health performance, and functional outcomes. Blood pressure is higher in late adolescence and early adulthood in ELBW/EP survivors compared with controls. In some studies, expreterm survivors have higher insulin and blood lipid concentrations than controls, which may also increase their risk for later cardiovascular disease. ELBW/EP survivors have more expiratory airflow obstruction than do controls. Those who had bronchopulmonary dysplasia (BPD) in the newborn period have even worse lung function than those who did not have BPD. As a group, they are unlikely to achieve their full lung growth potential, which means that more of them are likely to develop chronic obstructive airway disease in later life. Although they are smaller than term born controls, their weight gradually rises and ultimately reaches a mean z-score close to zero in late adolescence, and they ultimately attain a height z-score close to their mid-parental height z-score. On average, ex-preterm survivors have intelligence quotient (IQ) scores and performance on tests of academic achievement approximately 2/3 SD lower than do controls, and they also perform less well on tests of attention and executive function. They have similar high rates of anxiety and depression symptoms in late adolescence as do controls. They are, however, over-represented in population registries for rarer disorders such as schizophrenia and Autism Spectrum Disorder. In cohort studies, ex-preterm survivors mostly report good quality of life and participation in daily activities, and they report good levels of self-esteem. In population studies, they require higher levels of economic assistance, such as disability pensions, they do not achieve education levels as high as controls, fewer are married, and their rates of reproduction are lower, at least in early adulthood. Survivors born ELBW/EP will present more and more to health carers in adulthood, as they survive in larger numbers.

Objectives Prenatal testosterone is known to influence both cerebral laterality and 2nd to 4th digit ratio (2D : 4D). Epigenetic changes are thought to play some role in it. We studied sex-related differences between 2D : 4D and cerebral laterality in patients with schizophrenia and controls to examine the effects of prenatal testosterone in the development of schizophrenia. Methods Forty one men (18 schizophrenic patients and 23 controls) and 40 women (17 schizophrenic patients and 23 controls) were recruited from one psychiatric hospital in Korea. The 2D : 4D and electroencephalographic (EEG) coherence in 19 channels (66 pairs of interhemispheric coherence and 54 pairs of intrahemispheric coherence) were measured. The sex-related statistical analyses between 2D : 4D and EEG coherence in controls and patients with schizophrenia were performed using multiple regression. Results In male patients, the relationship between 2D : 4D and right intrahemispheric EEG coherence showed mainly positive correlation in delta and theta frequency bands, while it showed negative correlation in male controls. In female patients, the relationship between 2D : 4D and interhemispheric EEG coherence showed stronger positive correlation in alpha and beta frequency bands, while it showed weaker positive correlation in female controls. Conclusions Low prenatal testosterone may play certain roles in altered correlation between 2D : 4D and cerebral laterality in schizophrenia and the development of schizophrenia by epigenetic mechanism.
