The government, Ministry of Education, Science and Technology(MEST) presented a new policy that standardizes digital textbooks as a method to accept the change of education paradigm in 2006. Since 2007, MEST has begun to provide digital textbooks for some elementary schools. MEST proposes to change digital textbooks as a standard in elementary, middle, and high schools in the future. However, the use of digital textbooks has led to concern about the health of students. The purpose of this study was to identify health-adverse effects of the use of digital textbooks on the health of students. Literature reviews regarding digital textbooks including national and international literature were conducted. The literature reviews found the key physical and psychological factors to be considered in using digital textbooks. The physical factors were symptoms and signs associated with eye, musculoskeletal system, general health, and skin. The mental factors were 'burn out of study' and 'stress due to study'.

Objectives : The aim of this study was to investigate the value and efficacy of BDI, STAI, STAXI, ISI, and SCL-90-R in correlation with depression, anxiety, and insomnia patients. Methods : A total of 39 patients, who were diagnosed with depression, anxiety, and insomnia were evaluated using BDI, STAI, STAXI, ISI, and SCL-90-R. They were then statistically analyzed. Results : 1. BDI scores of depression patients were significantly different from other patients. 2. BDI scores of depression patients had strong positive correlation with STAI-S, and STAI-T scores. 3. STAI-S scores of anxiety patients had positive correlation with BDI, and ISI scores. 4. SCL-90-R depression subscale scores of depression patients had strong positive correlation with somatization, obsessive compulsive, interpersonal sensitivity, anxiety, hostility, phobic anxiety, paranoid ideation, psychoticism, global severity index, and positive symptom total subscale scores. 5. SCL-90-R anxiety subscale scores of anxiety patients had strong positive correlation with somatization, obsessive compulsive, depression, phobic anxiety, and global severity index subscale scores. Phobic anxiety subscale scores had strong positive correlation with anxiety, global severity index, and positive symptom total subscale scores. Conclusions : The result findings are expected to serve as a useful resource in future stress-related depression, anxiety, and insomnia case reports and clinical research in oriental neuropsychiatry.

Cancer survivor's self-help group may promote psychosocial adjustment in cancer patients. Self-transcendence has been shown to be related with crisis and adjustment in women with breast cancer. The purpose of this study is to determine the effectiveness of self-transcendence promoting program to facilitate self-transcendence, physical, and emotional well-being in women with breast cancer. Thirty patients who received mastectomy were recruited, but 9 subjects of experimental group and 14 subjects of control group participated in this study. Subjects of experimental group attended the self-help group for self-transcendence once a week for 6 weeks. Each session of program was proceeded for 2hours and the program contained activities for promoting self-transcendence, stress management, communication skill, exercise and relaxation, symptom management, and family support. Data were collected by self-reporting questionnaires within seven days after mastectomy and after the program was finished in experimental group, within 7 days after mastectomy and after 3 months in control group. Self-transcendence was assessed using the self-transcendence scale (STS) developed by Reed. Physical well being was assessed using Symptom distress scale (SDS) developed by McCorkle and Young and emotional well being was assessed using Profile of mood states (POMS). As a result, no significant differences were found between both groups in changes of self-transcendence, emotional well-being, and physical well-being. Self-transcendence score was significantly decreased in control group (p =0.16). But that of experimental group showed no decrease. In conclusions, when the self-transcendence promoting program is provided to the patients with breast cancer, it can be helpful for promoting self- transcendence. For the further study, repeated research with appropriate sample size and more intensive nursing intervention to promote self-transcendence is suggested. And reassessment after 6 months is recommended for testing long term effects of the program.

Objectives: The purpose of this study was to investigate the efficacy of Lijin-tang-gamibang on refractory gastroesophageal reflux disease (GERD). Methods: This before-and-after study compared the first medical examination and examination at the end of medical treatment. Twelve refractory GERD patients who visited the Department of Digestive Diseases of Kyung Hee University Korean Medicine Hospital from August 14th, 2017 to October 14th, 2017, were treated with Lijin-tang-gamibang for four consecutive weeks. The clinical characteristics of refractory GERD and the efficacy of herbal medical treatment was assessed by questionnaires, the Nepean Dyspepsia Index-Korean version (NDI-K), the Korean Gastrointestinal Symptom Rating Scale (KGSRS), the Numerical Rating Scale (NRS), the Korean version of the Perceived Stress Scale (KPSS-10), the Qi Stagnation Questionnaire (QSQ), the Spleen Qi Deficiency Questionnaire (SQDQ), and the Patient Global Impression of Change (PGIC). Prolonged effects were reported upon the follow-up telephone survey two weeks after treatment. Results: After treatment with the herbal medicine Lijin-tang-gamibang, the clinical characteristics of 12 refractory GERD patients were improved, especially in terms of the most common symptoms of acid regurgitation and heartburn. Each symptom score of NDI-K, KGSRS, NRS, SQDQ, and PGIC showed significant advances. Prolonged effects were reported in NDI-K, NRS and PGIC questionnaires two weeks after treatment. Conclusions: These results suggest that Lijin-tang-gamibang is an effective treatment for refractory GERD.

Objectives: This study aimed to investigate the 3-year mean periods aftermath of child sexual abuse and to compare the sexual violence victims regard to the treatment. Methods: 682 sexual violence victims were recruited by Seoul Sunflower Children Center, a nation-funded sexual violence victim protection center for children age 13, from 2004 to 2008. Data from 49 victims among 116 consented a follow-up, were analyzed. The victims were assessed by psychological test. Data was analyzed by SPSS ver. 15.0 (SPSS Inc.). Results: The average time elapsed from the last presumed sexual abuse was 39.7 months [standard deviation (SD) 26.02]. Overall, Children's Depression Inventory (CDI) was significantly decreased from 15.8 (SD 9.33) to 10.4 (SD 9.98), and several subscales (depression, anxiety, anger, posttraumatic stress, and dissociation) of Trauma Symptom Checklist for Children (TSCC) were also significantly decreased. CDI and TSCC scores showed no statistical difference between treatment-given and not-given groups, but Revised Children's Manifest Anxiety Scale (RCMAS) was decreased in treatment-given group, whereas it was increased in treatment-not-given group. The difference of RCMAS scores between the two groups was statistically significant [F(1,28)=4.54, p<0.05]. Conclusion: Sexually abused children showed overall symptom decreases over time, but anxiety was not decreased in treatment not-given group.

Object : Since autonomic nerve system dysfunction was known as the mechanism of panic disorder, many researchers used heart rate variability (HRV) as means of measuring autonomic nerve function of patients with panic disorder. We aimed to examine the effect of paroxetine medication for 3 months on symptom improvement and change of heart rate variability of the patients with panic disorder. Methods : The subjects were patients with panic disorder who visited the psychiatric outpatient clinic of Samsung Medical Center in Seoul. We included panic disorder patients who were aged from 20 to 50 and in normal BMI range (from 18 to 30) to minimize the effect of age and weight on HRV data. We excluded the patients with EKG abnormalities, hypertension or other major psychiatric disorders. They took 20-40 mg paroxetine medication a day for 3 months. Alprazolam was used only during the first month to control the acute panic symptoms and was tapered off after that. We measured the acute panic inventory (API), Hamilton rating scale for anxiety and depression (HAM-A & HAM-D), Spielberger state-trait anxiety inventory (STAIS, STAIT), and Beck depression inventory (BDI) in order to assess clinical improvement of the patients. And we measured time and frequency domain HRV in the resting, standing and cognitive stress states to assess the change of HRV. All measurements were done before and after paroxetine treatment. Result : After paroxetine medication, patients showed significant improvement in all psychiatric scales. In time domain of HRV, standard deviations of all R-R intervals (SDNN) were significantly increased in all states. In frequency domain of HRV, the ratio of high frequency to total power (HF/TP) in the standing state was significantly increased. Conclusion : After 3 months paroxetine medication, panic disorder patients showed significant clinical improvement and change in HRV data such as SDNN in all states and HF/TP ratio in the standing state. This result suggests that paroxetine medication is effective for the improvement of autonomic nerve system dysfunction in panic disorder patients.

Pathogen infection in plants induces complex responses ranging from gene expression to metabolic processes in infected plants. In spite of many studies on biotic stress-related changes in host plants, little is known about the metabolic and phenotypic responses of the host plants to Pseudomonas cichorii infection based on image-based analysis. To investigate alterations in tomato plants according to disease severity, we inoculated plants with different cell densities of P. cichorii using dipping and syringe infiltration methods. High-dose inocula (${\geq}10^6cfu/ml$) induced evident necrotic lesions within one day that corresponded to bacterial growth in the infected tissues. Among the chlorophyll fluorescence parameters analyzed, changes in quantum yield of PSII (${\Phi}PSII$) and non-photochemical quenching (NPQ) preceded the appearance of visible symptoms, but maximum quantum efficiency of PSII ($F_v/F_m$) was altered well after symptom development. Visible/near infrared and chlorophyll fluorescence hyperspectral images detected changes before symptom appearance at low-density inoculation. The results of this study indicate that the P. cichorii infection severity can be detected by chlorophyll fluorescence assay and hyperspectral images prior to the onset of visible symptoms, indicating the feasibility of early detection of diseases. However, to detect disease development by hyperspectral imaging, more detailed protocols and analyses are necessary. Taken together, change in chlorophyll fluorescence is a good parameter for early detection of P. cichorii infection in tomato plants. In addition, image-based visualization of infection severity before visual damage appearance will contribute to effective management of plant diseases.

After parturition, woman in childbed's health can grow worse. Because when woman in childbed gives birth, Genital organ can be damaged, and lost a lot of blood, and also consume a lot of physical strengths. So, after parturition, woman in childbed is easy to fall in disease if do not take care in health specially. So after parturition, woman in childbed should be careful in stress, sleep, food etc. This thesis described Postpartum Spasm[痙病], Oppressive Feeling and Dizziness[鬱冒], Constipation[便秘], Abdominal Pain[腹痛], Diarrhea[下利], Annoyance[煩亂] and Vomitting Sickness[嘔逆]. Postpartum Spasm[痙病]'s major symptom is rigided body. This disease corresponds to Tetanus in modem medicine, and bacterial infection is assumed for cause. By Oriental medicine, after parturition, when blood is lacking, if patient takes wind, this disease breaks out. Oppressive Feeling and Dizziness[鬱冒]'s major symptom is dizzy head and gloomy eye. After parturition, when blood is lacking, if patient sweats too much and take cold, this disease breaks out. After parturition, if patient consumes a lot of resins of human body, Constipation[使秘] breaks out. There are four causes to Abdominal pain[腹痛]. First, due to deficiency and cold treats by Danggwisaenggangyangyuktang(當歸牛薑羊肉湯). Second, due to stagnation of Gi(氣) treats by Jisiljakyaksan(枳實芍藥散). Third, due to blood stasis treats by Ha-eohyeoltang(下瘀血湯). Fourth, due to lochiorrhea treats by Daeseunggitang(大承氣湯). After parturition, Annoyance[煩亂] and Vomitting Sickness[嘔逆] due to fever of difficiency treat by Jukpidaehwan(竹皮大丸). After parturition, Febrile diarrhea[熱性下利] treats by Baekduonggagamchoagyotang(白頭翁加甘草阿膠湯). This disease is similar with present Bacillary Dysentery. After parturition, Exteroceptive disease due to taking wind treats by Yangdaltang. Due to wind and fever treats by Jukyeoptang(竹葉湯).

Objectives: We investigated the impacts of indoor plants on indoor air quality and occupational health, focusing on allergic rhinconjunctivitis and stress among employees in new office buildings. Methods: A total of 34 employees working at new public office buildings were enrolled as subjects (n=17, with indoor plants) and as a control (n=17) group. Before and after introducing indoor plants for three months, indoor air quality measurements including VOCs and aldehydes and questionnaires on sick building syndrome, AR symptoms (ARIA based), stress (DASS 42, KOSS, and SACL), and indoor characteristics were performed and statistically analysed. Results: Among the 34 enrolled subjects, 19 were included in the probable AR subject group (subjects with indoor plants, n=8, control n=11) and completed all questionnaires. Statistical analyses were done for total, AR subject groups, and controls. As a result, it was confirmed that major indoor air pollutants decreased after the introduction of indoor plants (p<0.5). Among major symptoms of allergic rhinoconjunctivitis, watery rhinorrhea, nasal stuffiness, and nasal itching indexes decreased (p<0.5, respectively). A decrease was noted in some areas of work-related stress indexes (mainly KOSS) among the subject group (total and AR) and a decrease of indoor environmental attractiveness among the control group (total and AR) (p<0.5, for all). Conclusions: Indoor plants may help reduce indoor air pollutants and decrease AR symptoms and work-related stress of employees in newly built office buildings. Various further follow-up studies on the mechanism of environmental, physical, and emotional influences and utilization of indoor plants in association with allergic diseases will be needed.
