Son Boyoung,Kim Daeho,Yoon Kyung Seu,Cho Seungwon 대한우울조울병학회 2023 우울조울병 Vol.21 No.2

Background: The post-traumatic stress disorder (PTSD) Checklist (PCL)-5, originally a 20-item self-questionnaire, has provided abbreviated versions of the checklist. This study aimed to test the diagnostic utility and validity of four brief versions of PCL-5 in a sample of adults seeking treatment at a psychiatric outpatient unit in a South Korean university-affiliated hospital. Methods: The sample comprised 97 adults diagnosed with PTSD and 130 diagnosed with other psychiatric disorders seeking treatment. Each abbreviated scale was examined with the area under the receiver operating characteristic curve (AUC), sensitivity, specificity, and positive predictive power. Additionally, internal consistency, correlation with full scale, convergent validity, and concurrent validity were investigated. Results: All four versions demonstrated excellent discriminative power, with AUC values of >0.9. Suggested cut-off scores were 6, 8, 11, and 16 for the short four-item version (S4), PCL4, PCL6, and PCL8, respectively. Internal consistency was adequate or good except for S4. Additionally, brief scales demonstrated good convergent validity with depression and anxiety scales and excellent concurrent validity with other PTSD scales. Conclusion: This study confirms the excellent diagnostic utility and adequate validity of four abbreviated versions of the Korean translation of PCL-5 in the clinical trial.

Son, Boyoung,Jung, Miewon The Korean Ceramic Society 2012 한국세라믹학회지 Vol.49 No.5

$Al_2O_3$/NiO powder was obtained through hydrolysis-condensation reactions and thermal treatments. An organic additive, triblock copolymer surfactant P123, was added to the starting materials to control the surface area and morphology. The synthesized powder was characterized by X-ray diffractometry (XRD), field-emission scanning electron microscopy (FE-SEM) and a Brunner-Emmett-Teller surface analysis (BET). The heterogeneous catalytic activity of this powder was applied to an epoxidation reaction of styrene and was monitored using a gas chromatograph with mass spectrophotometry (GC/MS).

Son, Boyoung,Jung, Miewon Materials Research Society of Korea 2012 한국재료학회지 Vol.22 No.10

Silica-based ceramic-matrix composites have shown promise as advanced materials for many applications such as chemical catalysts, ceramics, pharmaceuticals, and electronics. $SiO_2$-CuO-$CeO_2$ multi-component powders and their thin film, using an oxalic acid template as a chelating agent, have larger surface areas and more uniform pore size distribution than those of inorganic acid catalysts. $SiO_2$-CuO-$CeO_2$ composite powders were synthesized using tetraethylorthosilicate, copper (II) nitrate hemi (pentahydrate), and cerium (III) nitrate hexahydrate with oxalic acid as template or pore-forming agent. The process of thermal evolution, the phase composition, and the surface morphology of these powders were monitored by thermogravimetry-differential thermal analysis (TG-DTA), X-ray diffractometry (XRD), field-emission scanning electron microscopy (FE-SEM), and energy dispersive X-ray spectrometry (EDXS). The mesoporous property of the powders was observed by Brunner-Emmett-Teller surface (BET) analysis. The improved surface area of this powder template with oxalic acid was $371.4m^2/g$. This multi-component thin film on stainless-steel was prepared by sol-gel dip coating with no cracks.

본 연구는 다문화가정 자녀의 심리적 적응에 있어 주요하게 작용하는 보호요인에 대해 대해 심층적으로 이해하는 것을 목적으로 하였다. 이를 위해 다문화가정 자녀 16명을 대상으로 심층 인터뷰를 진행하였고 전사된 인터뷰 자료에 대해 분석팀을 구성하여 합의적 질적분석방법(CQR)을 사용하여 분석하고 분석결과에 대해 감수를 받았다. 연구결과, 다문화가정 자녀들의 심리적 적응을 돕는 보호요인은 4개 영역(나에 대한 믿음, 나를 돌보는 방법을 배움, 가까운 사람들의 응원을 받음, 지역사회의 도움)으로 확인되었으며 이와 관련한 13개의 하위 범주가 도출되었다. 이러한 연구 결과를 통해 다문화 가정 자녀에 대한 심리 상담 개입에 있어 함의와 이들을 돕기 위한 다문화 인식 전환과 관련한 교육에 대한 시사점을 제시하고 후속 연구에 대한 제한점을 논의하였다. The purpose of this study is to understand the protective factors for the psychological adaptation of youth from multicultural families. For this, 16 youth from multicultural families were interviewed and the data were analyzed using the consensual qualitative research (CQR) and checked by supervisor. As a result of the study, the protective factors for the psychological adaptation of youth from multicultural families are derived from 4 categories and 13 subfactors. 4 categories included belief in me, learning how to take care of me, being supported by close people, and helping the community. Condering these findings, we discuss the implications of counseling interventions for youth from multicultural families and education for multicultural awareness and present the limitations of subsequent research.

Purpose : This study aims to investigate the effect of instrument-activities daily living training through client-centered home visitation on the cognitive functions, occupational performance, and instrument-activities daily living of elderly at the cognitive support grade(Grade6). Methods : The subject of this study was a 66-year-old woman living in G Metropolitan City, who has been diagnosed with Alzheimer's and mild dementia. The study period was from March 17, 2020 through June 12, 2020, and the A-B-A' design, among the individual case experiments, was adopted as the study design. For the data analysis, descriptive statistic and visual analysis using graph were used for the change of cognitive functions, occupational performance, and instrument-activities daily living. Results : The instrument-activities daily living provided through client-centered home visitation improved the subject's cognitive functions, occupational performance(performance, satisfaction) and instrument-activities daily living. Conclusion : This study showed that daily life training through client-centered home visitation can help elderly people at the cognitive support grade select for themselves the problems of daily life caused by cognitive decline and practice specific action plans, thereby enabling them to maintain and improve the cognitive functions necessary for the performance of activities, such as comprehension, memory, and thinking skills. In addition, it is thought that the activities based on the subject's preferences, performance, and sense of importance assured the subject of feelings of motivation and the possibility of participation, and had a positive effect on the subject’s performance speed and rate. With the above in mind, Instrument-activities daily living client-centered home visitation is proposed as a potential practical intervention program for individuals. It can help elderly people at cognitive support grade to maintain and improve their functions, thereby delaying the progress of their condition to severe dementia.

Park, Boyoung,Jung, Kyu-Won,Oh, Chang-Mo,Choi, Kui Son,Suh, Mina,Jun, Jae Kwan Williams & Wilkins Co 2014 Medicine Vol.93 No.20

<P><B>Abstract</B></P><P>Diabetes is associated with a poor prognosis for liver disease, particularly in chronic hepatitis carriers. We investigated the prevalence of factors associated with impaired glucose tolerance (IGT) including diabetes and impaired fasting glucose (IFG) among individuals with hepatitis B virus (HBV) infection.</P><P>We used data from the Korean National Health and Nutrition Examination Survey, a nationwide cross-sectional survey conducted between 2007 and 2011. Sociodemographic information was collected using a structured questionnaire. The HBV surface antigen, liver enzymes, and lipid profile were measured from blood samples.</P><P>IFG was found in 18.1% of HBV carriers and 19.3% of noncarriers (<I>P</I> = 0.25). Diabetes was observed in 10.0% of HBV carriers and 12.2% of noncarriers (<I>P</I> = 0.08). Lower level of educational attainment was associated with a higher prevalence of IGT: high school education (odds ratio [OR] = 1.94 [95% confidence interval (CI) 1.14–3.29] and less than a high school education (OR = 3.20 [95% CI, 1.66–6.15] vs more than or equal to a college education. Elevated alanine transaminase and triglyceride by 10 were associated with increased risk of IGT (OR = 1.10 [95% CI, 1.01–1.20] and OR = 1.04 [95% CI, 1.01–1.07], respectively). Being a man and older in age were associated with a higher prevalence of IGT, and individuals with a low body mass index were at lower risk for IGT.</P><P>Given the synergistic effect of diabetes and HBV infection on liver disease prognosis, we recommend targeted IGT screening and follow-up for HBV carriers. These efforts should include health policies and intervention programs aimed at reducing educational disparities and encouraging early control of elevated liver enzymes or lipid profiles.</P>

Ten-Year Changes in the Hepatitis B Prevalence in the Birth Cohorts in Korea : Results From Nationally Representative Cross-Sectional Surveys

Park, Boyoung,Jung, Kyu-Won,Oh, Chang-Mo,Choi, Kui Son,Suh, Mina,Jun, Jae Kwan Williams & Wilkins Co 2015 Medicine Vol.94 No.41

<P><B>Abstract</B></P><P>To compare the prevalence of hepatitis B virus (HBV) infection over a 10-year period in terms of population-level trends, we established hypothetical birth cohorts that represented each 10-year interval age group.</P><P>We used data from the Korean National Health and Nutrition Examination Surveys conducted between 1998 to 2001 and 2008 to 2011. Trends in the HBV infection were calculated using data from individuals aged 20 to 59 years in 1998 to 2001 and those aged 30 to 69 years in 2008 to 2011.</P><P>In 2008 to 2011, the prevalence of HBV infection, as measured using serum HBV surface antigen (HBsAg) seroprevalence, among participants aged 30 to 69 years was 4.2% (95% CI = 3.7–4.7%), which represents a 1.3% absolute change and 20% change in prevalence ratio, which was significant compared with the prevalence among those aged 20 to 59 years in 1998 to 2001 (5.5%, 95% CI = 4.7–6.3%). The prevalence of HBV infection decreased most in the lowest income group, with marginal significance in males (<I>P</I> = 0.06) and significance in females (<I>P</I> = 0.03). In terms of education, females with at least a high school education showed a significant decrease (<I>P</I> = 0.03).</P><P>Using a birth cohort approach, the prognosis for HBV infection in terms of death or hospitalization, or resolution upon antiviral treatment of their HBV infections, identified by a decrease in the HBsAg seroprevalence was worse in the lower income group and in females with higher education. We postulate that these socioeconomic inequalities were caused by alcohol consumption, disparities in liver cancer surveillance, and access to antiviral treatment because of cost and reimbursement guidelines.</P>

Growth hormone (GH)-releasing peptides (GHRPs) and GH secretagogues (GHSs) are listed in the World Anti-Doping Agency (WADA) Prohibited List. In the present study, we developed and validated a method for the simultaneous analysis of seven GHRPs (alexamorelin, GHRP-1, -2, -4, -5, -6, and hexarelin) and three GHSs (anamorelin, ibutamoren, and ipamorelin) in human urine. Method validation was performed at minimum required performance levels specified by WADA technical documents (2 ng/mL) for all substances, and the method was validated with regard to selectivity (no interference), linearity (R2 > 0.9986), matrix effects (50.0%-141.2%), recovery (10.4%-100.8%), and intra- (2.8%-16.5%) and inter-day (7.0%-22.6%) precisions. The limits of detection for screening and confirmation were 0.05-0.5 ng/mL and 0.05-1 ng/mL, respectively.
