The purpose of this study was to identify the influencing factor on Symptoms of Stress of Middle Aged Women. The subjects of this study were 35 middle aged women who lives in Seattle, Washington in U.S, and 74 middle aged women who lives in Seoul. Data collection was performed at the University of Washington and Seoul from Oct. 1998 to May. 1999. Data collected through 4 types of questionnaires : SOS, Ways of Coping, Mood Status, Perceived Stress. The results of this study are as follows: 1. The stress symptoms showed positive correlation with emotion-oriented coping, mood status, and perceives stress. 2. Stepwised multiple regression analysis revealed that most powerful predictor of Stress Symptoms was mood status. A combination of perceived stress, mood status and ways of coping account for 64% of the variance in Symptoms of stress in Middle aged women. From the results of the study, the following recommendations are presented as follow: 1. It is necessary to replicate this study with a larger sample. 2. It is necessary to develop a stress management program focused on ways of coping, mood status, perceived stress for middle aged women.

2.Job Hazard Analyses for Musculoskeletal Disorder Risk Factors in Pressing Operations of Dry-cleaning Establishments.
Safety and Health at Work 2016;7(4):389-393
Job hazard analyses were conducted to assess exposure to musculoskeletal disorder (MSD) risk factors in seven workers of three dry-cleaning establishments. In accordance with the Washington State Ergonomics Rule, the analyses were performed in two separate steps: (1) observation and checklist approaches were made to identify a “caution zone job” in the seven workers' pressing operations across the three shops; and (2) detailed posture and motion analyses were undertaken to determine a “MSD hazard” in one worker's operation using a video technique. One “caution zone job” was identified and it was the pressing operation job in which five physical risk factors were found in the pressing operations. The detailed analyses confirmed that one “MSD hazard”, i.e., awkward posture in shoulders, was prevalent in the pressing operations of the three dry-cleaning facilities. It would be desirable to reduce MSD risk factors including awkward shoulder posture in the dry-cleaning industry.

Segmentation of fundamental heart sounds–S1 and S2 is important for automated monitoring of cardiac activity including diagnosis of the heart diseases. This pa-per proposes a novel hybrid method for S1 and S2 heart sound segmentation using group sparsity denoising and variation mode decomposition (VMD) technique. In the proposed method, the measured phonocardiogram (PCG) signals are denoised using group sparsity algorithm by exploiting the group sparse (GS) property of PCG signals. The denoised GS-PCG signals are then decomposed into subsequent modes with specific spectral characteristics using VMD algorithm. The appropriate mode for further processing is selected based on mode central frequencies and mode energy. It is then followed by the extraction of Hilbert envelope (HEnv) and a thresholding on the selected mode to segment S1 and S2 heart sounds. The performance advantage of the proposed method is verified using PCG signals from benchmark databases namely eGeneralMedical, Littmann, Washington, and Michigan. The proposed hybrid algorithm has achieved a sensitivity of 100%, positive predictivity of 98%, accuracy of 98% and detection error rate of 1.5%. The promising results obtained suggest that proposed approach can be considered for automated heart sound segmentation.

BACKGROUND: Use of universal leukoreduction for prevention of leukocyte associated transfusion reactions is common practice in many countries. This study was conducted in order to evaluate the performance of a newly developed leukoreduction filter for red blood cells (RBCs), the RF300 (Kolon Industries, Inc, Gumi, Korea). METHODS: Filtration time, RBC recovery, residual leukocyte count, and leukocyte removal rate were evaluated. To assess the quality of RBCs after filtration, percent hemolysis was monitored for a period of 21 days. Performance of the RF300 (N=78) was compared with that of the Bio-R O2 plus (Fresenius, Hamburg, Germany), the Pall Purecell RC (Pall Co., Washington, USA), and the Sepacell R-500N (Asahi, Tokyo, Japan). RESULTS: The shortest filtration time was observed using the RF300 (P<0.05). Using the RF300, recovery of RBC was 96.5%, which was higher than that of two filters (P<0.05). Mean residual leukocyte count was 0.26x10(6)/unit, with a leukocyte removal rate of 3 log. Using the RF300, mean percent hemolysis was 0.32% at day 21, which was comparable with that of two filters, but lower than that of one filter (P<0.05). CONCLUSION: The RF300 meets all established quality requirements for conduct of safe and effective leukoreduction of RBCs.

PURPOSE: The purpose of this study is to understand the relations of demographic and clinical characteristics, psychopathology and ways of coping with psychosocial adjustment of epileptic patients. METHODS: The participants were 200 epileptic outpatients. They completed Korean version of Washington Psychosocial Seizure Inventory (K-WPSI), Symptom Check List-90-Revised (SCL-90-R) and The Ways of Coping Checklist (WCC). RESULTS: The results showed that frequency of seizure, education level, socioeconomic level, occupation, all of subscales in SCL-90-R and passive coping styles were significantly related to overall psychosocial functioning of epileptic patients. The global severity index score that indicated present psychopathology of SCL-90-R best explained overall psychosocial functioning. And the frequency of seizure, education level, socioeconomic level, occupation, and somatization were also significant factors. The global severity index score was explained by emotional focused coping, socioeconomic level, frequency of seizure, and problem focused coping. CONCLUSIONS: The results of this study suggested that psychosocial adjustment of epileptic patients showed a significant relations with psychopathology, clinical and socioeconomic factors and the ways of coping.

6.Perspectives of International Human Epigenome Consortium.
Genomics & Informatics 2013;11(1):7-14
As the International Human Epigenome Consortium (IHEC) launched officially at the 2010 Washington meeting, a giant step toward the conquest of unexplored regions of the human genome has begun. IHEC aims at the production of 1,000 reference epigenomes to the international scientific community for next 7-10 years. Seven member institutions, including South Korea, Korea National Institute of Health (KNIH), will produce 25-200 reference epigenomes individually, and the produced data will be publically available by using a data center. Epigenome data will cover from whole genome bisulfite sequencing, histone modification, and chromatin access information to miRNA-seq. The final goal of IHEC is the production of reference maps of human epigenomes for key cellular status relevant to health and disease.

7.Less Pulsatile Levodopa Therapy (6 Doses Daily) Is Associated with a Reduced Incidence of Dyskinesia
Journal of Movement Disorders 2019;12(1):37-42
OBJECTIVE: To evaluate whether less pulsatile levodopa therapy (LPT) can reduce the development of levodopa-induced dyskinesia (LID). METHODS: This is a retrospective cohort study of patients with Parkinson’s disease at the movement disorders clinic of Medstar Washington Hospital Center. The study was not blinded or randomized. Patients were seen between August 2002 and August 2018. During these years, we treated patients with less pulsatile (6 doses daily) levodopa treatment to reduce LID. Occurrence of LID was recorded. RESULTS: Ninety-five patients with Parkinson’s disease taking levodopa were divided into two groups: 1) patients who were initially managed on LPT or who switched from traditional therapy (TT) (n = 61) (mean disease duration: 7.7 ± 4.8 years, mean levodopa duration: 5.6 ± 4.5 years and mean observation time: 4.3 ± 3.4 years), and 2) patients on TT throughout the observation period or until they developed dyskinesia (n = 34) (mean disease duration: 8.3 ± 3.8 years, mean levodopa duration: 6.2 ± 4.2 years and mean observation time: 4.1 ± 3.4 years). Three of the 61 LPT patients developed dyskinesia during the observation period. One of the patients developed dyskinesia after being switched to pulsatile doses by another doctor. In the other two, dyskinesia was minimal. In contrast to this 4.9% cumulative incidence, dyskinesia occurred in 50% (17/34) of TT patients, an incidence similar to that in published data (p < 0.001). CONCLUSION: Less pulsatile levodopa with 6 daily doses was associated with a low incidence of LID. Further study of this method of treatment is warranted.

8.Evaluation of Mood at Mental Status Examination in Geriatric Patients.
Journal of Korean Geriatric Psychiatry 1998;2(2):120-125
Among the elderly, affective disorders constitute the most commenly encountered psychiatric illness. Evaluation of Mood in the elderly patients is important because of uniqueness of senile depression. Depression in the elderly may present with various clinical symptoms such as chronic pain, multiple somatic complaints, or even dementia (pseudodementia). Also the seriousness of depression in the elderly is shown by the increase in and success of suicidal attempts among this group. About 15% of the total deaths of patients with affective disorder are due to suicide. Although some elderly depressed individuals presently atypically, most can be diagnosed according to the Washington University research criteria, which form the basis for the DSM-IV. In view of the effective therapies available for depression, it is especially crucial to make the diagnosis and proceed with treatment. The auther also reviewed rating scales of depression.

Environmental Health and Toxicology 2013;28(1):e2013009-
OBJECTIVES: Geographic Information Systems (GIS) is a powerful tool for assessing exposure in epidemiologic studies. We used GIS to determine the geographic extent of contamination by perfluorooctanoic acid, C8 (PFOA) that was released into the environment from the DuPont Washington Works Facility located in Parkersburg, West Virginia. METHODS: Paper maps of pipe distribution networks were provided by six local public water districts participating in the community cross-sectional survey, the C8 Health Project. Residential histories were also collected in the survey and geocoded. We integrated the pipe networks and geocoded addresses to determine which addresses were serviced by one of the participating water districts. The GIS-based water district assignment was then compared to the participants' self-reported source of public drinking water. RESULTS: There were a total of 151,871 addresses provided by the 48,800 participants of the C8 Health Project that consented to geocoding. We were able to successfully geocode 139,067 (91.6%) addresses, and of these, 118,209 (85.0%) self-reported water sources were confirmed using the GIS-based method of water district assignment. Furthermore, the GIS-based method corrected 20,858 (15.0%) self-reported public drinking water sources. Over half (54%) the participants in the lowest GIS-based exposure group self-reported being in a higher exposed water district. CONCLUSIONS: Not only were we able to correct erroneous self-reported water sources, we were also able to assign water districts to participants with unknown sources. Without the GIS-based method, the reliance on only self-reported data would have resulted in exposure misclassification.

Journal of the Korean Society of Plastic and Reconstructive Surgeons 2010;37(5):607-612
PURPOSE: Maxillectomy for malignant tumor resection often leads to functional and aesthetic sequalae. Reconstruction following maxillectomy has been a challenging problem in the field of head and neck cancer surgery. In this article, we described three dimensional midface reconstructions using free flaps and their functional and aesthetic outcomes. METHODS: We reconstructed 35 cases of maxillectomy defects using 9 radial forearm free flaps, 7 lattisimus dorsi musculocutaneous free flaps, 6 rectus abdominis musculocutaneous free flaps, 4 fibular osteocutaneous free flaps, and 9 anterolateral thigh free flaps, respectively. We classified post-maxillectomy defects by Brown's classification.1 Articulation clarity was measured with picture consonant articulation test. Swallowing function was evaluated with the University of Washington quality-of-life Head and Neck questionnaire by 4 steps. Aesthetic outcomes were checked to compare preoperative with postoperative full face photographs by 5 medical doctors who did not involve in our operation. RESULTS: The average articulation clarity was 92.4% (100-41.9%). 27 (81.9%) patients were able to eat an unrestricted diet. Aesthetic results were considered excellent in 18 patients (51.4%). Functional results were best in the group reconstructed with fibular osteocutaneous free flap. Considering the range of wide excision, aesthetic results is best in the group reconstructed with anterolateral thigh free flap. CONCLUSION: The free flap is a useful technique for the reconstruction of the midface leading to good results, both functionally and aesthetically. Especially, because osteocutaneous flap such as fibular osteocutaneous free flap offered bone source for osteointegrated implant, It produces the best functional results. And perforator flap like as anterolateral thigh free flap reliably provides the best aesthetic results, because it provides sufficient volume and has no postoperative volume diminution.
