  • The purpose of this study is to develop and evaluate the Korean version of the SERVPERF which has been widely used in order to measure service quality in various kinds of fields including social work. A total of 328 adults using social welfare centers in Seoul and Gyeonggi-do participated in this study. Confirmatory factor analysis confirmed that the Korean version of the SERVPERF consists of 5 dimensions(tangibles, reliability, responsiveness, assurance, and empathy) like the original SERVPERF. 5 dimensions of the Korean version of the SERVPERF have acceptable levels of internal consistency. Its convergent validity and discriminant validity are satisfactory. Finally, weak or non-significant correlations between 5 dimensions of the Korean version of the SERVPERF and social desirability scale indicated that the participants' reponses to the Korean version of the SERVPERF were not affected by social desirability.

  • Hydrophilic silica nanoparticles (SNPs) were treated by using 3-glycidoxypropyltrimethoxy silane (GPTMS) and then they were blended with polyurethane-urea (PUU) emulsions to obtain SNPs/PUU nanocomposite films. Thermo-mechanical properties of the nanocomposite films were investigated by varying the grafted amount of GPTMS onto SNPs and the contents of SNPs in the PUU matrix. The thermo-mechanical properties of the nanocomposite films were also compared in terms of the dispersibility of SNPs in the PUU matrix and thermal curing of the GPTMS-grafted SNPs. The maximum amount of grafted GPTMS was $1.99{\times}10^{-6}\;mol/m^2$, and which covered ca. 53% of the total SNP surface area. $^{29}Si$ CP/MAS NMR analyses with the deconvolution of peaks revealed the details of polycondensation degree and patterns of GPTMS in the surface modification of SNPs. The surface modification did not significantly affect colloidal stability of the SNPs in aqueous medium; however, the hydrophobic modification of SNPs offered a favorable effect on the dispersibility of SNPs in the PUU matrix as well as better thermal stability. XRD patterns revealed that GPTMS-grafted SNPs broadened the reduced the characteristic peak of polyol in PUU matrix. The composite films became rigid and less flexible as the SNP content increased from 5 wt.% to 20 wt.%. Particularly, Young's modulus and tensile modulus significantly increased after the thermal curing reaction of the epoxy groups in the SNPs.

A Pilot Study of Brief Eye Movement Desensitization and Reprocessing(EMDR) for Treatment of Acute Phase Schizophrenia (급성기 정신분열병의 치료로서 단기적인 안구운동 민감소실 및 재처리요법에 대한 예비연구)

  • Objectives : Eye movement desensitization and reprocessing(EMDR) is a novel, time-limited psychotherapy originally developed for treatment of psychological trauma. The effectiveness of this therapy has been validated only for posttraumatic stress disorder ; however, EMDR is often applied to other psychiatric illnesses, including other anxiety disorders and depression. This pilot study tested the efficacy of EMDR added to the routine treatment for individuals with acute stage schizophrenia. Methods : This study was conducted in the acute psychiatric care unit of a university-affiliated training hospital. Inpatients diagnosed with schizophrenia were randomly assigned to either three sessions of EMDR, three sessions of progressive muscle relaxation(PMR) therapy, or only treatment as usual(TAU). All the participants received concurrent typical treatments(TAU), including psychotropic medication, individual supportive psychotherapy and group activities in the psychiatric ward. The Positive and Negative Syndrome Scale(PANSS), the Hamilton Depression Rating Scale and the Hamilton Anxiety Rating Scale were administered by a clinical psychologist who was blinded to the patients' group assignment. Results : Forty-five patients enrolled and forty patients(89%) completed the post-treatment evaluation. There were no between-group differences in the withdrawal rates of patients during the treatment or at the three-month follow-up session. All three groups improved significantly across each of the symptomatic domains including schizophrenia, anxiety, and depressive symptoms. However, a repeated measures ANOVA revealed no significant differences among the groups over time. Effect size for change in total PANSS scores was also similar across treatment conditions, but effect size for negative symptoms was large for EMDR(0.60 for EMDR, 0.39 for PMR and 0.21 for TAU only). Conclusion : These findings supported the use of EMDR in treating the acute stage of schizophrenia but the results failed to confirm the effectiveness of the treatment over the two control conditions in three sessions. Further studies with longer courses of treatment, more focused target dimensions of treatment, and a sample of outpatients are necessary.

  • Background: Ginseng has been used as a tonic for invigoration of the human body. In a previous report, we identified a novel candidate responsible for the tonic role of ginseng, designated gintonin. Gintonin induces $[Ca^{2+}]_i$ transient in animal cells via lysophosphatidic acid receptor activation. Gintonin-mediated $[Ca^{2+}]_i$ transient is linked to anti-Alzheimer's activity in transgenic Alzheimer's disease animal model. The previous method for gintonin preparation included multiple steps. The aim of this study is to develop a simple method of gintonin fraction with a high yield. Methods: We developed a brief method to obtain gintonin using ethanol and water. We extracted ginseng with fermentation ethanol and fractionated the extract with water to obtain water-soluble and water-insoluble fractions. The water-insoluble precipitate, rather than the water-soluble supernatant, induced a large $[Ca^{2+}]_i$ transient in primary astrocytes. We designated this fraction as gintonin-enriched fraction (GEF). Results: The yield of GEF was approximately 6-fold higher than that obtained in the previous gintonin preparation method. The apparent molecular weight of GEF, determined using sodium dodecyl sulfate-polyacrylamide gel electrophoresis, was equivalent to that obtained in the previous gintonin preparation method. GEF induced $[Ca^{2+}]_i$ transient in cortical astrocytes. The effective dose (ED50) was $0.3{\pm}0.09{\mu}g/mL$. GEF used the same signal transduction pathway as gintonin during $[Ca^{2+}]_i$ transient induction in mouse cortical astrocytes. Conclusion: Because GEF can be prepared through water precipitation of ginseng ethanol extract and is easily reproducible with high yield, it could be commercially utilized for the development of gintoninderived functional health food and natural medicine.

  • This study aims to identify utilization status of medical care and factors to affect quality of life in diabetes mellitus patients. The research selected 6,146 adults aged over 50, who appeared with EQ-5D, from the Korean health panel. We analyzed states of medical care utilization using descriptive statistics. Multiple regression analysis was used to examine the main factors associated with quality of life in diabetes patients. The result shows that quality of life(EQ-5D) in diabetes is significantly associated with gender, age, insurance type, education level, household income, diabetes ambulatory medical cost and the number of ambulatory medical utilization for other diseases. Females, higher age, lower levels of education, medicaid, the lower household income, the higher diabetes ambulatory medical cost, and the higher the number of ambulatory medical utilization for other diseases were the significant factors of lower quality of life. Therefore, it is necessary to develop effective social programs and individualized approach to improve the quality of life in diabetes patients. In the future, these findings can be used as important data for health care policy and assessment.

  • Objectives: This study was conducted to help clinical studies for treating Functional Dyspepsia with acupuncture. We inspected tendency of studies of acupuncture treatment for functional dyspepsia and analyzed the assessing instrument for it by scrutinizing Pubmed recent publications. Materials and Methods: We inspected 8 theses and scrutinized their objectives, periods, participants, materials and methods, the instrument of assessment for the studies, and criteria and symptom score for questionaire, results and JADAD score. Results: 1. Most studies were published by oriental doctors except one which was published by an American doctor. More and more studies are being published in America and written in English recently. So it is considered that western doctors think that the acupuncture treatment is useful as unorthodox medicine for functional dyspepsia. 2. Among the 4 clinical studies, 2 studies were RCT and 1 study was not RCT and 1 study with vagueness. All 4 clinical studies were not double-blinded because they were about comparison between acupuncture treatment and medicine. 3. ST36, PC6, CV12, BL21 were chiefly used, and auricular point, ST40, SP6 were also used. Manual acupuncture were used in 2 studies, and low frequency pulse and electroacupuncture were used in other studies respectively. 4. 4 clinical studies used 0~3 points symptom score as the instrument of assessment. Additional assessments were on gastric emptying time, EGG and plasma level of motilin. All thesis were not verified of validity and reliability. 5. Among the 4 reviewed thesis, 2 theses were about acupuncture as one of the various treatment of functional dyspepsia, and the other 2 theses were about efficacy of acupuncture treatment. And the result generally showed effectivity of acupuncture treatment. Conclusion: Acupuncture treatment for functional dyspepsia is considered useful as in unorthodox medicine by western doctors, and it is necessary to provide objective instrument for assessing acupuncture treatment for functional dyspepsia.

  • The purpose of this study was to examine the news attributes of the nuclear waste storage facility in Wido by conducting content analysis of two newspapers (Chosun Ilbo and Hangyoreh) and Ohmynews. Furthermore, this study measured the effects of news attributes on readers' attitude, opinion, and recognition of the event. The results of the content analysis indicated that all three newspapers focused on event-oriented coverage than issue-oriented one. Also, they only dealt with two issues-decision making process of the residents and rewards for residents-among a total of nine issues. That is, according to the hypothesis of the second-level agenda-setting theory, the media emphasize on a particular attribute while ignoring other attributes, which, in turn, make the particular attributes more salient. Based on the results of content analysis, this study conducted an experiment to measure the effects of media attributes on public recognition toward the attributes in terms of cognitive and of affective aspects. The results showed a significant relationship between media attributes and public attributes, which confirmed the effects of the second-level agenda setting. However, the transfer of attributes did not take place in affecting public opinion and public recognition of the event itself.

  • The purpose of this study was to survey basic data for management of elderly day care centers. In this study, occupation, leisure life, and food, clothing and habituation, as well as social relationship, health state and behavior, and general characteristics of subjects were examined to identify the factors affecting their cognition, need and preference of the day care centers. The subjects of this study were 392 elderly, aged 60 years or over, living in Gangnung and neighboring districts. Data were collected by educated interviewers from November 4 through November 22, 2002. The subjects were interviewed face to face, one for one after the interviewee's agreements on the survey. The collected data were analysed with logistic regression analysis by SAS (statistical analysis system). Logistic regression analysis was done to identify affecting factors for cognition, need and preference of the elderly day care centers. The major findings are as follows: 1. The factors affecting cognition for the day care centers were analysed. The subjects with an occupation and a lower satisfaction level of living environment and friendship, who were economically secure enough to manage a sudden accident, showed a higher level of cognition of the day care centers. The subjects with a higher level of mental health state and a lower level of IADL also showed a higher level of cognition. On the general characteristics younger female subjects showed a higher level of cognition. 2. The subjects with a lower level of perceived economic condition who did not own their housing and were not economically safe enough to manage a sudden accident, had showed a higher level of need for the day care centers. It showed that the subjects with a high level of mental health state, a bad eye sight and dental condition, a good perceived health condition, and a lower level of IADL, needed the centers. 3. The subjects who had an occupation, however, not capable of making their own daily expenses, and a low occupation satisfaction level, and who did not own their housing, and were economically poor not enough to manage a sudden accident, showed a higher preference for the day care centers. The subjects with higher levels of friendship satisfaction and perceived health condition, not living with their spouse, and a higher education level, showed a higher preference for the centers. In conclusion, the common factors affecting their cognition, need and preference of the day care centers were occupation, economic security enough to manage accidents, and friendship satisfaction level. Especially, the subjects who had an occupation, however, not economically secure enough to manage accidents, and who did not live in their own housing with a good perceived health condition, showed high levels of need and preference for the day care centers. These results can be used as basic data to develop the efficient elderly day care centers, thus contribute to the elderly welfare in a local community.

  • Both bronchial leiomyoma and pulmonary sequestration are rare conditions, and to the best of our knowledge there are no reports of the two conditions coexisting. We report a female patient with bronchial leiomyoma with acquired pulmonary sequestration who presented with dyspnea, cough and purulent sputum. The patient had been treated for pneumonia at a local medical clinic. but was transferred to our clinic beacausr there was no clinical improvement. A 3-D computed tomography scan revealed a 1.5 cm sized mass near the distal portion of the left main bronchus and an anomalous artery arising from the aorta. The patient showed clinical improvement after a left lower lobectomy and a ligation of the anomalous artery.

  • The purpose of this study is to find out the effect of job rotation on employees' motivation and satisfaction. That is, it is the ultimate aim to know why employees want job rotation or why not, whether the rotation has an effect on their motivation, and finally whether the motivation gives direct job satisfaction. As a result of the survey, the efficiency and procedure of job rotation have influence on motivation. The employees also think that regular rotation can help them to find the proper position to meet their aptitude. And motivation also affects employees' achievement, benefits, and relationship with their bosses. Especially, when they feel great achievement and pride in their jobs, their satisfaction appeared to be very high. And when they are paid properly in comparison with their workload, or they learn special knowledge from their bosses, they usually content themselves.
