Objectives: To investigate the neurophysiological effect of acupuncture treatment on insomnia patients using quantitative electroencephalography (QEEG) and standardized Low Resolution Brain Electromagnetic Tomography method (sLORETA).Background: Insomnia is one of the commonly encountered symptoms in primary medical care. Recent studies of acupuncture for insomnia reported that the acupuncture groups showed significant improvements compared with the control groups. However, the neurophysiological mechanism of acupuncture in the treatment of insomnia has not been revealed and a few studies have measured the effect of acupuncture treatment using QEEG.Methods: Participants who had some problems in initiating or maintaining sleep, or had non-restorative sleep for more than 3 days a week and ISI scores above 8 and below 21 were treated by acupuncture for 2 weeks (3 times a week, total 6 times). We assessed the effectiveness of acupuncture for insomnia by the PSQI (Pittsburgh Sleep Quality Index) at baseline and at 2 weeks after the end of treatment (4th week). Also, we performed EEG and analysed the EEG data at baseline and at the end of treatment (2nd week) on the linked ears montage using the Neuroguide software program and sLORETA.Results: Thirty-two participants were enrolled and 2 participants dropped out because of personal reasons. Among the 30 participants, EEGs of 12 participants were included in the analysis of QEEG and sLORETA. Total score on the ISI and PSQI was significantly decreased after acupuncture treatment. The number of electrodes exceeding the range of 90% (±1.65) or 95% (±1.96) in the z scored absolute power of beta was significantly decreased after acupuncture treatment. There was no significant change in brain activation between pre- and post-acupuncture using sLORETA.Conclusions: The deviation of absolute power compared to the normative database was significantly decreased after acupuncture treatment in the alpha and beta ranges. Therefore, we suggest that acupuncture treatment for insomnia might be effective through the central nervous system especially in the brain. There are many limitations to drawing any conclusion. Further studies are needed in the future to overcome these limitations.

Objectives : The aim of this study was to investigate Post Traumatic Stress Disorder (PTSD)-related symptom severity, level of functional impairment and personality profiles between full-blown PTSD, partial PTSD and non-PTSD groups among 59 adolescent survivals from the Incheon fire disaster. Method : Using Short Screening Scale for DSM-IV PTSD, victims of the disaster were assigned to a full-blown PTSD group (n=18), a partial PTSD (n=22), or a non-PTSD group (n=19). Assessments included the Beck Depression Inventory (BDI), the State-Trait Anxiety Inventory (STAI), the Impact of Event Scales (IES), the McBride's Degree of General Labor Loss, and the Korean Version of Temperament and Character Inventory (K-TCI). Results : Significantly severe PTSD symptoms (F=4.832, df=2, p<.05) and functional impairment (F=12.144, df=2, p<.01) were demonstrated by PTSD groups as compared to the non-PTSD group. Interestingly, full and partial PTSD did not differ in these comparisons. Similarly, the subtypes of PTSD did not differ with respect to personality profiles using the K-TCI ; however, personality profiles were sharply differentiated between the PTSD and non-PTSD group. Conclusion : Although high subject homogeneity and small sample size may limit the results of this study, the present results highlight the possibility of the underestimation as well as the insufficient, treatment and compensation of partial vs full PTSD.

Background: Breast cancer is a major health problem among women around the world. Recent developments in screening and treatment have greatly improved the prognosis of patients with breast cancer in developed countries. However, in developing countries breast cancer mortality remains high.Breast cancer awareness is a first and important step in reducing breast cancer mortality. The development of a validated instrument to measure breast cancer awareness is crucial for the understanding and implementation of suitable health education programs to facilitate early deletion and minimize mortality. Objective: The objective of this study was to develop an instrument for the assessment of breast cancer awareness in Thai women. Materials and Methods: This methodological study was conducted in two stages: (1) literature searches and semi-structured interviews were conducted to generate items of the breast cancer awareness scale (B-CAS) which were subsequently examined for content and face validity, and (2) an exploration of the factor structure of the resulting instrument and an examination of its reliability. Data were collected using a self-administered questionnaire in Thai women aged 20-64 in August, 2015. Results: A total of 219 women (response rate 97.4 %) participated in this validation study. The B-CAS contains five domains with 53 items on breast cancer awareness: 1) knowledge of risk factors, 2) knowledge of signs and symptoms, 3) attitude to breast cancer prevention, 4) barriers of breast screening, and 5) health behavior related to breast cancer awareness. Items with a content validity index < 0.80 were excluded, and factor structure for the remaining items reflected the hypothesized five factor model. The scales based on all retained items was shown to have strongly internal consistency reliability (Cronbach's ${\alpha}=0.86$). Conclusions: The B-CAS provides good psychometric properties to assess breast cancer awareness in women. It can be used to examine breast cancer awareness in Thai women and it could lead to the development and evaluation of suitable educational interventions for raising breast cancer awareness. Future research should focus on further validating the B-CAS including an assessment of construct and criterion-based validity.
Objectives : This study looked at the symptoms of alexithymia in schizophrenia and their association with clinical variables and schizophrenic symptomatology. Methods Consecutive fifty eight inpatients with DSM-IV diagnoses of schizophrenia completed 26item version of Toronto Alexithymia Scale (TAS), Symptom Checklist-90-Revised(SCL-90-R), and Positive and Negative Syndrome Scale(PANSS). Results : Authors did not find any correlation between scores of PANSS and TAS. However, all the subscale scores of SCL-90-R were significantly correlated with total score of TAS. Also, 'difficulty identifying and deistinguishing between feelings and bodily sensations' and 'difficulty describing feelings' significantly correlated with SCL-90-R subscale scores. 'Reduced daydreaming' had mixed findings and 'externally oriented thinking' did not correlate. Multiple regression model included Global Severity Index of SCL-90-R accounting 28.2% of variance for TAS scores. Conclusion : These findings together with discrepancy in results between objective and subjective tests suggest that alexithymia in schizophrenia may have two constructs, 'difficulty to describe and communicate feelings(state)' and 'externally oriented thinking(trait)' Authors suggest further study needs to confirm construct validity of TAS in this population.
While it is well known that space environment can produce spacecraft anomaly, defining space environment effects for each anomalies is difficult. This is caused by the fact that spacecraft anomaly shows various symptoms and reproducing it is impossible. In this study, we try to find the conditions of when spacecraft failures happen more frequently and give satellite operators useful information. Especially, our study focuses on the geosynchronous satellites which cost is high and required high reliability. We used satellite anomaly data given by Satellite News Digest which is internet newspaper providing space industry news. In our analysis, 88 anomaly cases occurred from 1997 to 2008 shows bad corelation with Kp index. Satellite malfunctions were likely to happen in spring and fall and in local time from midnight to dawn. In addition, we found the probability of anomaly increase when high energy electron flux is high. This is more clearly appeared in solar minimum than maximum period.
Objectives: We review the sleep problems of the alcohol dependence patients. Especially we are interested in the prevalence, the severity of symptoms, anxiety, depression, and sleep quality of restless legs syndrome (RLS) in the alcohol dependence patients. Methods: We recruit 86 alcohol dependence patients who were admitted from October 6th, 2008 to October 17th, 2008. We interviewed each patient and evaluated sleep questionnaires such as the Sleep Disorder Questionnaire (SDQ), the Pittsburgh Sleep Quality Index (PSQI) and the International Restless Legs Syndrome Study Group (IRLSSG) rating scale. The presence of RLS and its severity were assessed using the IRLSSG diagnostic criteria and the IRLSSG severity scale, respectively. Depression and anxiety were evaluated by the Beck Depression Inventory (BDI) and the Beck anxiety inventory (BAI). Results: Of all 86 patients, 59 patients have insomnia, 33 patients have RLS, 30 patients have Periodic limb movement disorder (PLMD), 29 patients have nightmare. RLS patients have more high score in the BAI ($21.70{\pm}10.36$ vs $14.67{\pm}11.98$), and their sleep quality was poor in the PSQI ($11.09{\pm}4.08$ vs $7.92{\pm}3.91$) than non-RLS patients. Conclusion: This study shows that alcohol dependence patients show many sleep problems such as insomnia and RLS. So we should notice that the sleep problems of alcohol dependence patients are important in clinical approach and treatment.

Background: Diagnosis of subpulmonary effusion is thought to be somewhat difficult more than pulmonary effusion. Clinical course and pathophysiology are thought to be different from typical pulmonary effusion. This study was done for increasing high suspicious index and early diagnosis of subpulmonary effusion. Method: Among the patients at dept. of chest medicine, National Medical Center from January 1990 to Dec. 1993, 232 cases of typical pulmonary effusion and 42 cases of subpulmonary effusion were studied. Result: 1) The ratio of subpulmonary effusion and typical pulmonary effusion was about 1:5. 2) Male to Female ratio was 1:1 in both effusion. 3) Rt. side pleural and subpleural effusion were slightly predominant. 4) Subjective symptoms are chest pain, cough and exertional dyspnea. There is no difference between subpulmonary and typical pulmonary effusion. 5) Duration of symptom was slightly longer in subpulmonary effusion. 6) The most common cases of pleural effusion is tuberculosis in both subpulmonary & typical pulmonary effusion. Non-specific pleuritis was more common in subpulmonary effusion. 7) Pleural effusion was recurred about one fifth in both subpulmonary & pulmonary effusion. Conclusion: We studied clinical course and laboratory findings between subpulmonary & pulmonary effusion. However there are no definite difference between subpulmonary & pulmonary effusion. Duration of symptom was slightly longer in subpulmonary effusion. Most common cause was tuberculosis. Non specific pleuritis was more prevalent in subpulmonary effusion.

The aim of this study was to identify the inhibitory effect of hepatic toxicity and liver lipid metabolism after the administration of Artemisia capillaris and Paecilomyces japonica. SD rats were divided into $CCI_4$ treated group with subgroups of 6% Artemisia capillaries (6A), 4% Artemisia capillaris+2% Paecilomyces japonica (4A2P), 3% Artemisia capillaris+3% Paecilomyces japonica (3A3P), 2% Artemisia capillaris+4% Paecilomyces japonica (2A4P) and 6% Paecilomyces japonica (6P). In this study we also intended to verify the optimum ratio of Artemisia capillaris and Paecilomyces japonica which can reduce hepatotoxicity. Artemisia capillaris and Paecilomyces japonica reduced cholesterol and triglyceride levels which were increased by the treatment of $CCI_4$. HDL-cholesterol level was the most enhanced in the group of 4A2P. On the other hand, athrogenic index (AI) was reduced statistically (p<0.05). When the ratio of Artemisia capillaris and Paecilomyces japonica was 2:1, the improvement of rat serum and liver lipid metabolism and the alleviation of hepatic damage induced by $CCI_4$ were shown to be the most effective in this study. It is considered that the symptoms of severe chemically induced hepatotoxicity could be lessened by Artemisia capillaris and Paecilomyces japonica administration.

This study assessed the risk and prevalence of anorexia as well as associated factors among home-dwelling elderly adults. The subjects were 419 elderly men (116) and women (303) aged 65 years and older ($76{\pm}5.6yr$) living in Korea. Data were collected by personal interviews using questionnaires. The collected data were analyzed by descriptive statistics and Pearson's correlation. The prevalence of anorexia was 35.1% among participants. Male elders (74.1%) had higher proportions of anorexia than female elders (20.1%) (P<0.001). Significant differences in the appetite were observed according to type of disease, depression, and activities of daily living (ADL) index. In the poor appetite group, central nervous system diseases were the primary illness in male elders (P<0.01), whereas endocrine diseases were the primary illness in female elders (P<0.01). Elders with good appetites had less symptoms of depression (P<0.001) and greater independence in ADL (P<0.001). These results explored the high prevalence of anorexia in geriatric populations in Korea and its impact on elderly nutritional status and health. Further research should be performed to identify the causes of anorexia and establish an intervention protocol allowing the early diagnosis of anorexia.
Objectives : The purpose of this study is to investigate the effect of Jeseupwiryeongtang-gagam(JWTG) on atopic dermatitis by in vivo experiment using NC/Nga atopic dermatitis mouse, which has histological and clinical similarities to the atopic dermatitis of human. Methods : To investigate the effect of JWTG on AD, we evaluated atopic dermatitis-like skin lesions by clinical skin index and analyzed immunological parameters in peripheral blood mononuclear cells(PBMCs), splenocytes, draining lymph node(DLN) and performed skin histology in ears and dorsal skin of atopic dermatitis-like skin NC/Nga mouse in vivo. Results and Conclusions : In vivo, clinical skin severity score were significantly lower in JWTG group than control group. IgE, IL-6, $TNF-{\alpha}$, IgM, IgG2a and IgG2b levels in serum were decreased remarkably in JWTG group than control group and $IFN-{\gamma}$ production, secreted in Th1 cell were increased by JWTG. After experiment ended, we analyzed immunological cells ($CD3^+$, $CD19^+$, $CD4^+$, $CD8^+$, $CD3^+$$CD69^+$, $CD4^+$$CD25^+$ and $CD49b^+$) by flow cytometry. It resulted that total absolute number of $CD3^+$, $CD19^+$, $CD4^+$ and $CD8^+$ cells were recovered as normal and $CD3^+$$CD69^+$ were decreased significantly compared with control group in isolated DLN and PBMCs from NC/Nga mouse and total absolute number of $Gr-1^+$, $CD11b^+$ and $CD3^+$ in dorsal skin of NC/Nga mouse were decreased by JWTG. We analyzed ear, DLN, and neck-back skin after biopsy and dyeing by hematoxyline/eosin(H&E) and toluidine staining (mast cells marker) and obtained results that JWTG were effective to histological symptoms (dermal and epidermal thickening, hyperkeratosis and inflammatory cell infiltration). Ear thickness was decreased significantly than the control group and the size of inflammatory lymphocytes cells(ILC) and plasma cells(PC) in DLN were also decreased.
