As numbers of serotonin's function are so many, studies of serotonin are numerous nowadays. In the beginning, concentration of metabolites such as 5-HIAA was a key issue, but recent studies have been challenged for serotonin receptor genes and their relation to mood disoder. Serotonin transporter(5-HTT) gene is a strong candidate gene of mood disoder for following reason. Serotonin transporter is a key protein in the serotonin pathway as it regulate the concentration of serotonin in the synaptic clept and essential pathophysiology of depression is dysregulation of 5-HTT so that all antidepressants have effect of 5-HTT antagonist. The decrease of 5-HTT in the platelet and in brain of the depressive patients is much consistent results in the studies of the pathophysiology of mood disorder till now. By this, we will be able to develop simple and easy marker for diagnosis, type, and treatment monitoring of depression. Many psychiatrists have sought the independent genes in relation to depression or schizophrenia. Obviously, the hereditary vulnerability contributes to etiology of mood disorders, but it is difficult to discriminate the independent genes because of many environmental factors. Moreover, in the hereditarily complex diseases such as mood disorder, the only vulnerability of gene can not sufficiently explain the etiology. In the future, to exclude the role of the gene-environmental interaction, the methods such as gene transfer can be considered. In the opposite direction, by using the gene destruction method, the role of target genes can be examined. As yet the concept of the gene expression, neural plasticity, neurogenesis and etc, is the elementary stage. The development of this field will help to establish the treatment strategy of chronic and refractory mood disorders.

This study investigated dieting behavior, awareness of body shapes, and eating disorders in female adolescents according to age and BMI. The Eating Attitude Test for Korean Adolescents (EAT-26KA) and sociocultural standards were used to measure eating disorders and sociocultural attitudes related to appearance, respectively. In addition, the BDI (Beck Depression Inventory) scale was used to measure the correlation between disordered eating and depression. The data were collected from 390 female adolescents living in Seoul and were analyzed using SPSS15.0. The results indicated that subjects wanted to be thinner despite having a normal body weight (BMI 19.35${\pm}$2.73). They also thought of themselves as fat and with desires to be slimmer, and viewed "diet and exercise" as the best way to lose weight. About 67.4% of the respondents had tried a diet and had experienced dizziness, anorexia, and general exhaustion while dieting. Also, 5.1% of the subjects were classified as eating disorder and suffered from stress to be thin. In addition, 85.0% of the subjects with eating disorder had tried a diet due to "appearance". They thought that "being underweight" was an ideal body image and considered themselves fat, although their BMIs were in the normal range (19.94${\pm}$2.02). In terms of symptoms during dieting, many of the subjects dealing with an eating disorder felt dizzy, had low energy, and were depressed. In conclusion, we must educate young females about healthy eating and positive body image to prevent the development of adolescent eating disorders.

Purpose: The purpose of the study is to investigate the degree of fatigue and its related factors in women with rheumatoid arthritis. Method: The subjects were 143 patients with rheumatoid arthritis. Data were collected by questionnaires including Multi-Dimensional Assessment of Fatigue(Tack, 1991), Korean Health Assessment Questionnaire(Bae et al., 1991), numeric scale of pain(Lee & Song, 1987), Center for Epidemiologic StudiesDepression, and Korean Sleep Scale(Oh, et al., 1998). The data were analyzed by SPSS WIN 12.0 program using descriptive statistics, Pearson Correlation, and Stepwise Multiple Regression. Result: The result were as follows. 1. The scores of fatigue of subjects averaged $4.95{\pm}1.83$, degree of fatigue was $5.85{\pm}1.98$, and influence of fatigue was $4.04{\pm}2.09$. 2. The mean score of the degree of physical dysfunction, pain, sleep disorder, and depression were $1.42{\pm}0.38,\;8.15{\pm}3.58,\;1.86{\pm}0.67,\;and\;1.85{\pm}0.46$ points respectively. 3. The subject's total fatigue score, physical dysfunction, pain, sleep disorder, and depression was correlated positively(r=.44, r=.28, r=.29, r=.27, p< .01). 4. The main influencing factors on the fatigue were physical dysfunction and sleep disorder. These two main variables made it possible to explain 23.0% of the variance in fatigue. Conclusion: Therefore, nursing interventions for fatigue experienced women with rheumatoid arthritis would be focused to decrease physical dysfunction and sleep disorder.

Background: Depression is the leading cause of lowering the quality of life of cancer patients and lung cancer is the most likely to cause depression. It is necessary to find out depression-related factors in lung cancer patients. Methods: The study was a retrospective cohort study using medical records, and was a non-equivalent comparison group design. It involved patients diagnosed of lung cancer at the Konkuk University Medical Center from January to December 2012. Between antidepressants prescription group and non prescription group, socio-demographic factors, clinical factors, treatment-related factors and other factors were analyzed statistically. Results: Antidepressant prescription group consisted of 23 people and non-prescription group of 206 people. Prescription rate of quetiapine was the highest 47.8% (11/23), followed by escitalopram (43.5%, 10/23), amitryptyline and trazodone (30.4%, 7/23). The prescription group was prescribed with an average of 1.9 antidepressants. Antidepressants were prescribed after average of 248 days from lung cancer diagnosis and prescription period per patient was average 177.5 days. According to the result of univariate logistic regression analysis between 2 groups, factors such as number of outpatient visit, number of admission, days of hospitalization, sleep disorder, and comorbidity were found to be statistically significant (p < 0.05). However, According multivariate logistic regression analysis showed that number of admission, days of hospitalization and sleep disorder were statistically significant (p < 0.05) excluding comorbidity. Conclusion: About 10% of lung cancer patients had received a prescription for antidepressants after lung cancer diagnosis. A sleep disorder, number of hospitalization and length of stay were identified as factors influencing the prescribing antidepressants.

Purpose: The study aimed to examine quality of sleep in hemodialysis patients and explore physical, physiological, and psychological factors determining sleep quality. Methods: The survey was conducted among 165 patients on maintenance hemodialysis at a university hospital. Data were collected from July to October in 2015. The sleep quality and its related factors were assessed by standardized questionnaires, anthropometric measures, and lab tests after obtaining a written consent from the participant. Results: The mean age of the participants was 62.58 years old, and 67.9% of the participants experienced sleep disorders such as 'not falling asleep within 30 minutes' or 'frequently waking up at night'. Pain (t=-3.29, p=.007) and depression (t=-6.028, p<.001) were significantly different between the group with sleep disorder and the other without. The demographic factors (age, shared room, sleep during the day), physical factors (pain and symptom), and psychological factors (depression and trait and status anxiety) together explained 20.0% of variance in sleep quality. Conclusion: Sleep disorder was frequently experienced among the patients on maintenance hemodialysis. The effective nursing strategies should focus on sleep environment, pain and depression management. Further study is warranted to explore the effect of physiological factors related to the disease on sleep disorder in this population.

Objectives: The present mini review aimed to summarize the existing knowledge regarding the beneficial and adverse effects of raloxifene in menopausal women. Methods: This study is a review of relevant publications about the effects of raloxifene on sleep disorder, depression, venous thromboembolism, the plasma concentration of lipoprotein, breast cancer, and cognitive function among menopausal women. Results: Raloxifene showed no significant effect on depression and sleep disorder. Verbal memory improved with administration of 60 mg/day of raloxifene while a mild cognitive impairment risk reduction by 33% was observed with administration of 120 mg/day of raloxifene. Raloxifene was associated with a 50% decrease in the need for prolapse surgery. The result of a meta-analysis showed a significant decline in the plasma concentration of lipoprotein in the raloxifene group compared to placebo (standardized mean difference, -0.43; 10 trials). A network meta-analysis showed that raloxifene significantly decreased the risk of breast cancer (relative risk, 0.572; 95% confidence interval, 0.327-0.881; P = 0.01). In terms of adverse effects of raloxifene, the odds ratio (OR) was observed to be 1.54 (P = 0.006), indicating 54% increase in the risk of deep vein thrombosis (DVT) while the OR for pulmonary embolism (PE) was 1.05, suggesting a 91% increase in the risk of PE alone (P = 0.03). Conclusions: Raloxifene had no significant effect on depression and sleep disorder but decreased the concentration of lipoprotein. Raloxifene administration was associated with an increased risk of DVT and PE and a decreased risk of breast cancer and pelvic organ prolapse in postmenopausal women.

Objective : The aim of the study was to investigate the difference in alexithymia between anxiety disorder and depressive disorder. The second was to evaluate the effect of alexithymia on quality of life in patients with anxiety disorder and depressive disorder. Methods : A total of 175 patients with diagnoses of anxiety disorder or depressive disorder were recruited. Demographic, psychosocial, and clinical data were analyzed, as well as results on the 20-item Toronto alexithymia Scale (TAS-20K), the Symptom Checklist-90-Re-vised (SCL-90-R), a quality of life scale, the Beck Depression scale, and Beck Anxiety Inventory. Results : As compared with the patients with anxiety disorder, patients with depressive disorder showed significantly higher total score on the TAS-20K and for factor 1 (difficulties identifying feelings) and factor 2 (difficulties describing feeling) scales of the TAS-20K and showed significantly lower scores of psychosocial well-being on the quality of life scale. Total scores on the TAS-20K correlated significantly with scores for some subscale on the quality of life scale. Conclusion : This study suggest that patients with depressive disorder had more alexithymic symptoms and worse quality of life compared with those with anxiety disorder. Also, alexithymic symptoms are found to be associated with quality of life. Therefore, clinicians should try to focus on relieving symptoms to help patients restore their psychological well-being and improve their quality of life.

Disorder of Extreme Stress, Not Otherwise Specified (DESNOS) is the proposed diagnosis that meets the severe, complex, and prolonged psychological sequela of victims with chronic traumatization (e.g., family violence, incest, and childhood sexual or physical abuse). The hallmarks of DESNOS are a multiplicity of symptoms (e.g., somatization, dissociation, and depression), pathological changes in relationships, identity disturbances, and a propensity to experience repeated harm and injury at the hands of oneself and others. DESNOS can be directly assessed by Structured Interview of Disorder of Extreme Stress (SIDES) and Self- Report Inventory of Disorder of Extreme Stress (SIDES-SR). The treatment of DESNOS should be phaseoriented and involve movement back and forth among three basic stages : 1) stabilization ; 2) trauma processing ; 3) reintegration.

Borderline personality disorder (BPD) is characterized by identity and interpersonal problem, affective dysregulation and pervasive severe impulsivity. Although sleep disturbances are not primary symptoms of BPD, they are important aspects of this disorder. However, clinicians and researchers did not give much attention to the sleep symptoms of BPD yet. Measured by nocturnal polysomnography, increased sleep latency as well as reduced total sleep time and sleep efficiency, and 'depression-like' REM abnormalities (i.e., reduced REM latency and increased REM density) are found in BPD patients. Co-morbid sleep disorders such as chronic insomnia, nightmare disorder or circadian rhythm sleep disorder associated with BPD have been reported. Clinicians should focus on the sleep complaints of BPD patients, and carefully manage such symptoms with sleep hygiene education, cognitive psychotherapy or light therapy.

The purposes of this paper is to study the characteristics of compared to the speakers voice without depression and speakers with depression, and to propose a objective method for the measurement of the therapeutic effects as well as for diagnostics of depression based on the characteristics. The voice samples obtained from 11 female speakers with depression, aged from 20 to 40, diagnosed as having major depressive disorder by an psychiatrist were compared with those from 12 normal controls with matched sex, age, height, weight, education, smoking, and drinking. The voice samples are taken by a portable digital recorder(TASCAM DR-07, Japan) and analysed using the MDVP(Multi-Dimentional Voice Program) software module from CSL(Computerized Speech Lab, kay elemetrics, co, model 4100). The result of the investigation are as following. First, the average speaking fundamental frequency and loudness range of the speakers with depression group was statistically significantly lower than that of the control group. The pitch range of the control group was rather higher than that of the speakers with depression group, but without statistical significance. Overall speech rates have no statistical difference between two groups. Second, the average speaking fundamental frequency and loudness range have statistically significant negative correlation with Beck Depression Inventory, i. e. more severe depression exhibits lower average speaking fundamental frequency and loudness range. Other vocal parameters such as pitch range and overall speech rate have no statistically meaningful correlations with Beck Depression Inventory.
