The results of this Study are as follows:33.6% of all participants have insomnia; 22.5% of those who have insomnia are DIS(difficulty in initiating sleep), 17.3% are DMS(difficulty returning to sleep once awakened) and 7.0% awakened too early. 3 4.8% experience sleepiness during daytime. Type 1, experiencing insomnia and sleepi ness during daytime together, is 12.0%, Type 2, with insomnia only, is 21.6%, Type 3, with sleepiness during daytime only, is 22.8% and 43.5% experience no sleeping disturbances. After studying only those with 3 types of sleeping disturbances, it is found that the most common cause of such disturbance is stress 88.4%, anxiety 56.0%, no apparent reason 33.8%, anxiety/fear/terror 29.3%, hurry 23.6%, alcohol/caffeine 16.9%, bedroom tem perature 11.1%, urination during nighttime and persons living together 10.7%, noise from inside 8.9%, illumination 8.0%, and pain/itch 5.8%. The one group revealed significant differences in residential environment(p=0.003). Sex, age, education level, medicine, monthly earning revealed no meaningful differences. Of sleeping behavior, mean duration of sleep latency(p=0.000), whether or not feeling freshness(p=0.000), whether taking enough sleep(p=0.029), whether taking regular sleep(p=0.005) showed significant differences depending on whether or not having insomnia, and mean duration of sleep time, time to sleep, time of rising, whether taking naps did not reveal significant differences. Of sleep behavior, time to sleep(p=0.000), whether taking naps(p=0.000), indicated significant differences. Of sleeping behavior, mean duration of sleep latency(p=0.000), whether or not feeling freshness(p=0.000), and whether taking enough sleep(p=0.000), time of going to bed (p=0.002), whether or not taking nap(p=0.000), whether or not taking regular sleep(p=0.010) indicated significant differences among the sleeping disturbance types.

황매향,박알뜨리,김혜랑 이화여자대학교 교육과학연구소 2022 교육과학연구 Vol.53 No.3

이 연구는 심리적 소진 연구에서 사용되는 국내 소진척도 개발 현황을 살펴보고 향후 심리적 소진척도 개발에 있어 시사점을 얻기 위해 수행되었다. 이를 위해 국내에서 사용되고 있는 심리적 소진척도 27개를 수집하였으며, 이들의 연도별 연구의 흐름, 대상별 소진척도의 특성 및 한계점을 살펴보고, 각 척도의 하위 구성 요인을 분석하였다. 주요 결과는 다음과 같다. 첫째, 국내에서는 2000년 이후 대부분의 소진 관련 척도 연구들이 등장하였으며, 분석 대상 논문의 과반수가 최근 10년간 이루어진 것으로 나타났다. 둘째, 다양한 대상에 따라 소진척도를 개발하여 사용하고 있지만, 특히 교사 및 학생에 대한 소진척도 개발 연구의 비중이 컸다. 셋째, MBI척도처럼 소진 증상을 측정하는 척도와 MBI에서는 측정하지 않는 직무환경 변인을 측정하는 척도로 분류되었다. 또한 소진 증상을 측정하는 경우, MBI의 하위 구성 요인을 모두 측정하고 있는 척도와 하위 요인 중 일부만 포함하는 척도로 분류되었다. 특히, 지속적으로 제기되고 있는 MBI 척도의 한계를 극복하기 위해 국내의 문화적 특성 및 직무의 특성을 반영한 척도 개발이 필요함을 확인하였다. 이 연구에서는 기존 척도의 한계점을 보완하여 국내 일반직 종사자들이 고유하게 경험하는 소진의 특성이 반영된 척도가 개발되어야 함을 후속 과제로 제안하였다. This study was conducted with the purpose of examining the development status of scales used in psychological research on burnout in Korea and determining implications for the development of a psychological burnout scale in the future. For this study, we collected 27 psychological burnout scales developed, validated, and adapted in Korea, and examined the flow of research by year, characteristics, and limitations of the burnout scales by subject, and analyzed the sub-factors of each scale. The results are as follows. First, in Korea, most psychological burnout scales have appeared since 2000, and more than half of the analyzed papers have been published in the last 10 years. Second, psychological burnout scales were developed, validated, and adapted according to various subjects, but psychological burnout studies on teachers and students were the most common. Third, they were classified into scales that measure burnout symptoms like the MBI scale and scales that measure work environment variables that are not measured by the MBI. In addition, when measuring the symptoms of burnout, they were classified into scales that measure all sub-components of the MBI and scales that include only some of the sub-factors. To overcome the frequently cited limitations of the MBI scale, it will be necessary to develop a scale that reflects the characteristics of Korean culture and work environment. It seems that a scale that can be used by overcoming the limitations of the existing scale for general occupational groups should be developed.

Ascorbic Acid and Citric Acid Reduce Explant Darkening during Shoot Tip Culture of Adonis amurensis

Hye Rang Park,Hyun Hwan Jung,Ki Sun Kim 한국원예학회 2006 Horticulture, Environment, and Biotechnology Vol.47 No.1

This study was conducted to reduce explant darkening during the shoot tip culture of Adonis amurensis. Explant darkening at initial stage of the culture was found to decrease the explant survival rate about 20%. To reduce the darkening, shoot tips were soaked in an antioxidant mixture of 150 ㎎ㆍL?¹ ascorbic acid and 150 ㎎ㆍL?¹ citric acid or in an antioxidant mixture of 300 ㎎ㆍL?¹ ascorbic acid and 300 ㎎ㆍL?¹ citric acid for 30 min before inoculation. In root development, in vitro multiple buds were cultured on MS (Murashige and Skoog) media containing antioxidants (150 ㎎ㆍL?¹ ascorbic acid, 150 ㎎ㆍL?¹ citric acid, or 150 ㎎ㆍL?¹ ascorbic acid + 150 ㎎ㆍL?¹ citric acid). When the explants were soaked in antioxidants, explant darkening significantly decreased and their survival rate was improved to 56%. When the antioxidants were added to the medium, on the other hand, the survival rate of explants was improved to 48%. However, phenolic compounds decreased during the culture without antioxidants, and little phenolic compounds were detected in more darkened explants. To prevent darkening, the antioxidant soaking treatment was more effective than the antioxidant addition to medium. In addition, combined treatment of the antioxidants was more effective to reduce the darkening than the single antioxidant treatment.

Hye Rang Park,Hyun Hwan Jung,Ki Sun Kim 한국원예학회 2005 Horticulture, Environment, and Biotechnology Vol.46 No.6

This research was conducted to micropropagate Adonis amurensis Regel et Radde through multiple bud induction for mass production. In vivo multiple bud was induced with 20 ㎎ㆍL?¹ thidiazuron (TDZ) after 200 ㎎ㆍL?¹ gibberellic acid treatment on rootstock, whereas in vitro multiple bud was induced on Murashige and Skoog (MS) media supplemented with TDZ. The highest in vitro multiple bud induction was obtained with 1.5 ㎎ㆍL?¹ TDZ for 12 weeks. In vitro root development was induced on MS medium supplemented with 0.1 ㎎ㆍL?¹ indole-3-butyric acid (IBA) for 4 weeks. In conclusion, it is recommended that multiple shoots can be induced in 1.5 ㎎ㆍL?¹ TDZ and root induced in 0.1 ㎎ㆍL?¹ IBA, respectively.

Degree and distribution of left ventricular hypertrophy as a determining factor for elevated natriuretic peptide levels in patients with hypertrophic cardiomyopathy: insights from cardiac magnetic resonance imaging.

Park, Jeong Rang,Choi, Jin-Oh,Han, Hye Jin,Chang, Sung-A,Park, Sung-Ji,Lee, Sang-Chol,Choe, Yeon Hyeon,Park, Seung Woo,Oh, Jae K Kluwer Academic Publishers 2012 INTERNATIONAL JOURNAL OF CARDIOVASCULAR IMAGING Vol.28 No.4

<P>Whether the left ventricular (LV) mass index (LVMI) and LV volumetric parameters are associated independently with natriuretic peptide levels is unclear in hypertrophic cardiomyopathy (HCM). Therefore, we investigated which parameters have an independent relationship with N-terminal pro-B type natriuretic peptide (NT-proBNP) levels in HCM patients using echocardiography and cardiac magnetic resonance imaging (CMR). A total of 103 patients with HCM (82 men, age 53 ± 12 years) were evaluated. Echocardiographic evaluations included left atrial volume index (LAVI) and early diastolic mitral inflow E velocity to early annular Ea velocity ratio (E/Ea). LVMI, maximal wall thickness and LV volumetric parameters were measured using CMR. The median value of NT-proBNP level was 387.0 pg/ml. The mean NT-proBNP level in patients with non-apical HCM (n = 69; 36 patients with asymmetric septal hypertrophy, 11 with diffuse, and 22 with mixed type) was significantly higher than in those with apical HCM (n = 34, P < 0.001). NT-proBNP level was negatively correlated with LV end-diastolic volume (LVEDV) (r = -0.263, P = 0.007) and positively with LVMI (r = 0.225, P = 0.022) and maximal wall thickness (r = 0.495, P < 0.001). Among the echocardiographic variables, LAVI (r = 0.492, P < 0.001) and E/Ea (r = 0.432, P < 0.001) were correlated with NT-proBNP. On multivariable analysis, non-apical HCM, increased maximal wall thickness and LAVI were independently related with NT-proBNP. Severity of LV hypertrophy and diastolic parameters might be important in the elevation of NT-proBNP level in HCM. Therefore, further evaluation of these parameters in HCM might be warranted.</P>

Slide Session : OS-ALG-07 ; Allergy : in Murine Model of Asthma A Six-Year Study on the Changes in Pollen Counts and Sensitization Rates in South Korea

( Hye Jung Park ),( Kyung Hee Park ),( Jae Hyun Lee ),( Jung Won Park ),( Chein Soo Hong ),( Kyu Rang Kim ),( Mae Ja Han ),( Hosoeng Choe ),( Jae Won Oh ) 대한내과학회 2014 대한내과학회 추계학술대회 Vol.2014 No.1

Background: The amount of airborne pollen is considered to be related to sensitization rates. The sensitization rates to tree pollen significantly increased and those to grass and weed pollen decreased over the last 30 years in South Korea. We evaluated short term changes of sensitization rates and the correlation with pollen counts. Methods: We assessed the number of pollen grains collected in Seoul. Tree pollen of the 15 species, weed pollen of the 8 species and grass were studied from January 1, 2007 to December 31, 2013. We retrospectively reviewed the results of 4,442 skinprick tests (SPTs) to 33 common inhalant allergens conducted in the Severance Hospital allergy clinics in Seoul from January 1, 2008 to December 31, 2013. Results: The pollen counts of tree, especially pine and corylus, and grass significantly decreased, as years go by. SPT results showed that the skin reactivity to grass significantly increased from 6.9% in 2008 to 14.0% in 2013. The sensitization rates to tree and weed pollen had no changes. In the details, the sensitization rates to Walnut, Popular, Bermuda, Timothy and Dandelion significantly increased. There was significant correlation between rate of change in pollen counts and sensitization rates to oak and hop J (Humulus japonicus). However, the others showed no correlation. Conclusions: Decrease tendency of pollen counts was observed in Seoul, over the seven years. Some species showed significant correlation between pollen counts and sensitization rates over the six years.

김혜랑(Hye Rang Kim),박혜영(Hye Young Park) 한국음악치료교육학회 2023 인간행동과 음악연구 Vol.20 No.2

본 연구는 NICU 고위험 신생아를 대상으로 시행된 국내·외 음악중재연구의 효과를 심박동수, 호흡수, 산소포화도, 행동상태 등의 활력징후와 음악 유형, 음악제공자, 회기 수 등의 중재 세부 사항에 따라 분석하고 평가하는 것을 목적으로 하였다. 이를 위해 국내·외 학술지 전자 데이터 베이스를 사용하여 음악중재와 NICU, 고위험 신생아, 활력징후 등을 검색어로 하여 2023년 3월까지 게재된 논문을 검색하였다. 검색 결과, 총 17편의 문헌이 최종 선정되었고 해당 연구에 포함된 음악에 대해 고찰 및 메타분석을 실시하였다. 연구 결과, NICU 고위험 신생아를 대상으로 한 음악중재에서 활력징후의 효과크기는 심박동수 0.433, 호흡수 효과크기는 0.568, 산소포화도 0.791, 행동상태 1.329의 중간 효과 또는 큰 효과로 확인되었다. 또한 주요 조절변수에 따라 효과크기를 비교 및 분석한 결과 음악 유형의 경우 라이브와 녹음을 혼합 방식으로 제공한 음악이, 음악제공자의 경우 심박동수는 음악치료사가, 그 외 산소포화도, 호흡 수, 행동상태에서는 비음악치료사가 음악을 제공한 경우 효과적이었으며, 총회기는 1회기 이상 5회기 이하가 상대적으로 효과적인 것으로 나타났다. 본 연구 결과는 고위험 신생아를 대상으로 한 음악의 임상적 가치를 확인하고 신생아집중치료실 음악중재 시 음악 요소, 음악 전달 방식, 음악 중재자 등에 대한 고려점을 제시했다는 데 그 의의가 있다. The purpose of this study was to analyze and evaluate music intervention research conducted with high-risk neonates in NICUs in both domestic and international settings. Seventeen music intervention studies were identified, and their characteristics, including type of music, music provider, and treatment frequency, and outcomes (i.e., neonatal vital signs) were reviewed and analyzed along with meta-analysis. For music interventions targeting high-risk neonates in NICUs, the effect sizes of the neonates’ vital signs were classified as either medium or large. In addition, larger effect sizes were associated with a combination of live and recorded music, nonmusical therapists as the music providers, and treatment frequency of one to five sessions per week. These research findings verify the clinical value of music for high-risk neonates and provide insights into the selection of music elements, music delivery methods, and music providers in NICU music interventions.
