  • For the modification of kiln drying schedule, relations between resistance to drying Rd and the moisture content or drying times were found for 4/4, 6/4 and 8/4 green Douglas fir heartwood by the mild drying schedule and the severe drying schedule until the average moisture content was about 10 percent. The results of this study were as follows. 1. Resistance to drying of thicker lumber was higher than that of thinner lumber and resistance to drying of three different thicknesses were negligible between the mild-and the severe drying schedule. The relationships between resistance to drying and two schedules or three thicknesses of lumber were $Rd_1=1.830{\times}10^5\;M^{-2.24}$ for 4/4 lumber by the mild drying schedule, $Rd_2=1.822{\times}10^5\;M^{-2.25}$ for 4/4 lumber by the severe drying schedule, $Rd_3=2.352{\times}10^5\;M^{-2.14}$ for 6/4 lumber by the mild drying schedule, $Rd_4=3.457{\times}10^5\;M^{-2.27}$ for 6/4 lumber by the severe drying schedule, $Rd_5=1.317{\times}10^6\;M^{-2.56}$ for 8/4 lumber by the mild drying schedule, $Rd_6=8.267{\times}10^5\;M^{-2.40}$ for 8/4 lumber by the severe drying schedule. 2. Thinner lumber exhibited lower level of moisture content and shorter drying time required at intersection point between the moisture content and resistance to drying as a function of drying time than those of thicker lumber. Drying time of mild drying was longer than that of severe drying and similar to the level of moisture content at intersection point.

  • Specific energy curves for water removal in vacuum-press drying of different thick softwoods of red pine (Pinus densiflora), white pine (Pinus koraiensis), larch (L. leptolepis) and Western hemlock (Tsuga heterophylla) were split into three sections: increased slowly, fairly constant, and increased rapidly. Calculated specific energy for 3, 5, 7, 9 and 11cm thick lumber was a value of 0.483, 0.649, 0.814, 0.977 and 1.138kWh/kg of water, respectively. Specific energy almost linearly increased as lumber thickness increased, and specific energy for severe schedule was less than that for mild schedule. Average specific energy was 0.712kWh/kg and vacuum-press drying consumed less energy as compared with any other drying methods.

  • Objectives: To experimentally assess the anti-depressant effects of Gammakdaejo-tang Complex Extracts (GMDJ-Tang) in rats. Methods: Twenty Wistar Hannover (160~170 g) stressed rats were treated with different concentrations of GMDJ-Tang extracts i.e., 0, 62.5 mg/kg, 125 mg/kg, and 250 mg/kg. Chronic mild stress was induced by food deprivation, empty bottles, forced swimming, flickered light, tilt cages, shaking cages, high density breeding, water deprivation, and by soaking the litter cover according to fixed schedule. Blood and brain tissue samples were collected for biochemical analysis. Tests included serotonin and ELISA assays. Results: GMDJ-tang increased the weight of treated rats as well as levels of serotonin, BDNF and TrkB; however, the differences were not significant. In contrast, the extracts significantly decreased blood glucose in stressed rats. GMDJ-tang extracts did not significantly impact Serum AST, ALT, leukocytes, erythrocytes and thrombocytes when comparing treatment groups to control rats. Likewise, hemoglobin, hematocrit and PLT increased in treatment groups following treatment with GMDJ-tang, but this change was without significance. Conclusions: These results suggest that GMDJ-tang can alleviate chronic mild stress in rats, possibly through anti-depressant activity.

  • This study was performed to evaluate the effects of Jowiseungchungtang and fluoxetine in the chronic mild stress(CMS) model of depression in rats. Chronic exposure to mild unpredictable stress was found to depress the consumption of sucrose solution in rats for 5 weeks. These CMS-treated rats were stratified into Jowiseungchungtang group, fluoxetine group and vehicle group. And control rats were also stratified into other CMS-treated group. The change of the consumption of sucrose solution was measured, and open field test were performed to investigate the anti-depression effect of Jowiseungchungtang and fluoxetine. The results were as follows : 1. The consumption of sucrose solution was significantly reversed in Jowiseungchungtang-treated group at 7 week, but there was no significant change in other groups. 2. CMS schedule decreased body weight. Jowiseungchungtang group and fluoxetine group showed significant decrease of body weight after 6 weeks. 3. In open field test, Jowiseungchungtang group and fluoxetine group showed no significant change of exploratory activity.

  • This study was carried out to estimate drying schedule of Fagaceae four species grown in Kangwon-Do by oven-drying at $100^{\circ}C$ which aimed to elucidate the characteristics such as current moisture content, drying process, initial check, collapse and internal check during drying following each board thickness (1.5cm, 2.5cm, 3.5cm, 4.5cm). The results were as follows; Current moisture content of each board showed a rapid drying curve with the high initial moisture content of board. With the high initial moisture content, the incease of board thickness and the slowness of changing rate of moisture content, species took long to do drying. Also, the initial conditions of drying had to be mild condition with the increase of board thickness.

  • Purpose: Several accelerated partial breast radiation (APBR) techniques have been investigated in patients with early-stage breast cancer (BC); however, the optimal treatment delivery techniques remain unclear. We evaluated the feasibility and toxicity of APBR delivered using intensity-modulated radiation therapy (IMRT) in elderly patients with stage I BC, using a novel fractionation schedule. Materials and Methods: Forty-two patients aged ${\geq}65$ years, with stage I BC who underwent breast conserving surgery were enrolled in a phase I/II study evaluating APBR using IMRT. Forty eligible patients received 40 Gy in 4 Gy daily fractions. Patients were assessed for treatment related toxicities, and cosmesis, before APBR, during, and after completion of the treatment. Results: The median age was 73 years, median tumor size 0.8 cm and the median follow-up was 54 months. The 5-year locoregional control was 97.5% and overall survival 90%. Erythema and skin pigmentation was the most common acute adverse event, reported by 27 patients (69%). Twenty-six patients (65%) reported mild pain, rated 1-4/10. This improved at last follow-up to only 2 (15%). Overall the patient and physician reported worst late toxicities were lower than the baseline and at last follow-up, patients and physicians rated cosmesis as excellent/good in 93% and 86 %, respectively. Conclusion: In this prospective trial, we observed an excellent rate of tumor control with daily APBR. The acceptable toxicity profile and cosmetic results of this study support the use of IMRT planned APBR with daily schedule in elderly patients with early stage BC.

  • Objectives : Only a few prospective studies of panic disorder are available. This study investigated naturalistic outcome of panic disorder patients at twelve months after the initial diagnosis. Methods : A total of 84 subjects were diagnosed with panic disorder by diagnostic interview, Structured Clinical Interview for DSM-IV (SCID-IV) and Anxiety Disorder Interview Schedule for DSM-IV (ADISIV). Among them, 80 subjects could be evaluated by means of Panic Disorder Severity Scale (PDSS) at follow-up interview after twelve months. Treatment continuation was also examined at follow-up interview. Results : At initial intake, 80 patients were classified into 22% with mild, 33% with moderate-to-marked, and 45% with severe symptoms on the basis of their PDSS total score. At twelve months, 20% of patients reached remission, 65% had mild and 15% had moderate-to-marked symptoms. Initial panic symptom severity, presence of agoraphobia, panic symptom duration before diagnosis, number of comorbid Axis I disorders were associated with significantly higher PDSS total score at twelve months. Forty six percent of total patients continued medication and 23% have stopped treatment by clinician's recommendation and 31% have selfdiscontinued their medication. At twelve months, all three groups were improved but self-discontinuation group had significantly higher PDSS total score. Conclusion : In the one-year naturalistic outcome study of panic disorder patients, high percentage of patients achieved remission or had mild symptoms.

  • Objectives: Vaccination is an important intervention for preventing disease and reducing disease severity. Universal vaccination programs have significantly reduced the incidence of many dangerous diseases among children worldwide. This study investigated the side effects after immunization in infants under 1 year of age in Lorestan Province, western Iran. Methods: This descriptive analytical study included data from all children <1 year old in Lorestan Province, Iran who were vaccinated according to the national schedule in 2020 and had an adverse event following immunization (AEFI). Data were extracted from 1084 forms on age, sex, birth weight, type of birth, AEFI type, vaccine type, and time of vaccination. Descriptive statistics (frequency, percentage) were calculated, and the chi-square test and Fisher exact test were used to assess differences in AEFIs according to the abovelisted variables. Results: The most frequent AEFIs were high fever (n=386, 35.6%), mild local reaction (n=341, 31.5%), and swelling and pain (n=121, 11.2%). The least common AEFIs were encephalitis (n=1, 0.1%), convulsion (n=2, 0.2%), and nodules (n=3, 0.3%). Girls and boys only showed significant differences in mild local reactions (p=0.044) and skin allergies (p=0.002). The incidence of lymphadenitis (p<0.001), severe local reaction (p<0.001), mild local reaction (p=0.007), fainting (p=0.032), swelling and pain (p=0.006), high fever (p=0.005), and nodules (p<0.001) showed significant differences based on age at vaccination. Conclusions: Immunization is a fundamental public health policy for controlling vaccine-preventable infectious diseases. Although vaccines such as the Bacillus Calmette-Guérin vaccine, oral poliovirus vaccine, and pentavalent vaccine are well-researched and reliable, AEFIs are inevitable.

  • This paper develops a Bayesian method to derive the optimal sequential preventive maintenance(PM) policy by determining the PM schedules which minimize the mean cost rate. Such PM schedules are derived based on a general sequential imperfect PM model proposed by Lin, Zuo and Yam(2000) and may have unequal length of PM intervals. To apply the Bayesian approach in this problem, we assume that the failure times follow a Weibull distribution and consider some appropriate prior distributions for the scale and shape parameters of the Weibull model. The solution is proved to be finite and unique under some mild conditions. Numerical examples for the proposed optimal sequential PM policy are presented for illustrative purposes.
