Background: The purpose of this study was to effect of prenatal exercise program combined with Brugger's exercise on low back pain and balance in pregnant women. Design: A Single-Subject Study. Methods: This study was applied to 28 weeks of pregnant women who complained of low back pain for a total of 4 weeks. A total of 10 prenatal exercise programs in this study consists of sessions, and each session was applied with a Bruger exercise for 1 minute before the start. For the fatigue and safety of pregnant women, a break for 1 minute was provided for each session and was conducted under the supervision of the therapist The visual analogue scale (VAS), Oswestry disability index (ODI), and static balance (BT-4) were measured to evaluate the pregnant women's low back pain and balance ability before and after the intervention Results: The change in back pain after the intervention was VAS 5 before the intervention, but the VAS gradually decreased at 4 weeks after the intervention. Reduced to VAS 2 after 4 weeks of intervention. The Oswestry Disability Index (ODI) was 54%, which was at the level of severe disability, but the dysfunction index gradually decreased 4 weeks after intervention, reaching 19% in 4 weeks, and there were no problems with daily life. As for the static balance ability, the sway area and the sway distance values gradually decreased after the intervention in both the eyes open and closed state, showing an improvement in the static balance ability of pregnant women after the intervention than before the intervention. Conclusion: The prenatal exercise program combined with Brugger's exercise was effective to improve low back pain and static balance in pregnant women. The result of this study may helpful as basic data for obstetric physical therapy.

Background and objective: This study was carried out to assess the relationship between the internal and external environments and the ecological items in five sites with a high level of artificial use intensity prior to the establishment of Geumgang River riparian ecological belts. Methods: The sites were classified into forest type, cultivated land type and urbanized type in accordance with their respective locational types. Ecological items including plant ecology such as proportion, naturalization index and urbanization index of native species were analyzed and animal ecology such as the number of species and population of wild birds, amphibians and reptiles, mammals, and butterflies and dragonflies, which are indicator insects, were investigated. In addition, species diversity indices of wild birds, butterflies and dragonflies found in all the subject lands were computed. Results: Among the plant ecological items, the ratio of native species in the forest type was higher than 90%, which was a satisfactory level, while the naturalization and urbanization indices were less than 10%. The number of species in the animal ecological characteristics was reduced in the order of forest type, cultivated land type and urbanized type. As the results of correlation analysis, the internal area of the planted area showed a negative correlation with the total of individuals. The area of grasslands showed a positive correlation with the number of dragonfly species and the total number of individuals, thereby illustrating that wet grasslands have positive effects. The area of surrounding forests, as an external environment, had a negative correlation with the urbanization index (UI) but a positive correlation with the inhabitation of butterflies and the total number of species. Conclusion: The results confirmed the need for more diversified special compositions including planted land, grassland, wetland, bodies of water and waterways within the subject land in the wetland ecological belt along with the need for surrounding forest location and preservation from the perspective of purchase and restoration of land for enhancement of wider biodiversity in the future.

이 연구의 목적은 초등 과학 및 타 교과 교과서에 대한 Romey의 참여지수를 보고한 선행 연구들의 비교를 통해 교육과정 시기별 초등 과학 교과서의 탐구 성향의 변화 및 그 적절성에 대해 검토하는 것으로, 연구 결과를 요약하면 다음과 같다: 첫째, 본문 지수(T)의 경우, 제3차 교육과정 과학 교과서는 극히 탐구적인 교과서로 판정되는 값이지만(T>18), 이후 지속적으로 감소하며, 2007 개정 및 2015 개정 교육과정 교과서는 각각 권위적(비탐구적)인 교과서로 판정되는 값(T=0.25)과 적절한 탐구 수준의 교과서로 판정되는 값(T=0.99)에 근접한다. 수시 개정 체제 이후 과학 및 타 교과 교과서의 T값을 비교해보면 별 차이가 없는 수준이다; 둘째, 그림 · 도표 지수(FD) 또한 교육과정 시기별로 지속적으로 감소하는 양상이다(제3차 과학 교과서 : FD>2.75 → 2015 개정 과학 교과서 : FD=0.14). 특히 2015 개정 과학 교과서의 FD값은 비탐구적인 교과서로 판정되는 수준으로, 최근 보고되고 있는 타 교과 교과서의 FD값과 비교해도 낮은 수치이다; 셋째, 과학 교과서의 활동 지수(A)의 경우, 제3차부터 2015 개정 교육과정 국정 교과서에 이르기까지 점차 감소하지만 모두 탐구하기에 알맞은 교과서로 판정되는 값이다(제3차 과학 교과서 : A=1.12 → 2015 개정 과학 교과서 : A=0.64). 하지만 7차 교육과정 시기 이후 과학 교과서의 A값은 타 교과 교과서와 비교하여 전반적으로 낮은 편이다. 넷째, 과학 교과서의 질문 지수(Q)는 전술한 세 지수(T, FD 및 A)에 비해 극히 제한적으로 보고되었는데, 이는 교육과정 시기별 과학 교과서 구성 체계의 차이가 주된 원인으로 보인다.

이 연구는 주요 국가의 국가도서관 목록에 나타나고 있는 한국관련 자료의 실태분석을 위해 한국관련 주제명의 주제별 특성과 레코드의 소장상황, 그리고 한국입장에서 쟁점이 되고 있거나 관심이 높은 일부 주제명을 중심으로 그 특성을 비교 분석한 것이다. 연구결과를 요약하면 아래와 같다. 첫째, 미국 등 일부 국가를 제외하고 대부분의 국가도서관에 저장되어 있는 한국관련 레코드가 절대적으로 부족하며, 일본관련 레코드와 비교할 때 대략 2~3배 이상 적게 나타나고 있다. 둘째, 한국관련 레코드의 세부항목별 주제 분포에서 대체로 '역사'와 '경제'가 가장 많게 나타나고 있지만 대부분의 국가에서 '한국전쟁'이 많은 비중을 차지하고 있는 것은 한국에 대한 외국인의 인식이 왜곡될 가능성이 높다고 생각된다. 셋째, 한국관련 레코드가운데 대부분이 북한에 비해 남한관련 레코드가 1.5~5배 이상 많게 나타나고 있지만 폴란드, 이탈리아, 멕시코는 오히려 북한이 많게 나타나고 있다. 넷째, 한국관련 주제명 가운데 '태권도', '김치', '독도', '동해' 등의 용어는 국가마다 미묘한 차이점이 드러나고 있지만, 우리의 주변 국가를 제외하고는 대부분 미국의회도서관의 주제명표기와 거의 일치하고 있다. 다섯째, 특히 우리의 인접국인 중국과 일본의 경우, 자국의 정치적, 역사적 입장을 철저하게 반영하여 나타냄으로써 일부 주제명의 표기에 문제점이 발견되고 있다.

This study investigates the utility of the Triglyceride-glucose(TyG) index and Cardiometabolic Index(CMI) as predictors for diagnosing metabolic syndrome. The study involved 1970 males, 1459 females, totaling 3429 participants who underwent health checkups at P Hospital in Busan between January 2023 and June 2023. Metabolic syndrome diagnosis was based on the presence of 3 or more risk factors out of the 5 criteria outlined by the American Heart Association/National Heart, Lung, and Blood Institute(AHA/NHLBI), and participants with 2 or fewer risk factors were categorized as normal. Statistical analyses included independent sample t-tests, chi-square tests, Pearson's correlation analysis, Receiver Operating Characteristic(ROC) curve analysis, and logistic regression analysis, using the Statistical Package for the Social Sciences(SPSS) program. Significance was established at p<0.05. The comparison revealed that the metabolic syndrome group exhibited attributes such as advanced age, male gender, elevated systolic and diastolic blood pressures, high blood sugar, elevated triglycerides, reduced LDL-C, elevated HDL-C, higher Cardiometabolic Index, Triglyceride-glucose index, and components linked to abdominal obesity. Pearson correlation analysis showed strong positive correlations between waist circumference/height ratio, waist circumference, Cardiometabolic Index, and triglycerides. Weak positive correlations were observed between LDL-C, body mass index, and Cardiometabolic index, while a strong negative correlation was found between Cardiometabolic Index and HDL-C. ROC analysis indicated that the Cardiometabolic Index(CMI), Triglyceride-glucose(TyG) index, and waist circumference demonstrated the highest Area Under the Curve(AUC) values, indicating their efficacy in diagnosing metabolic syndrome. Optimal cut-off values were determined as >1.34, >8.86, and >84.5 for the Cardiometabolic Index, Triglyceride-glucose index, and waist circumference, respectively. Logistic regression analysis revealed significant differences for age(p=0.037), waist circumference(p<0.001), systolic blood pressure(p<0.001), triglycerides(p<0.001), LDL-C(p=0.028), fasting blood sugar(p<0.001), Cardiometabolic Index(p<0.001), and Triglyceride-glucose index (p<0.001). The odds ratios for these variables were 1.015, 1.179, 1.090, 3.03, and 69.16, respectively. In conclusion, the Cardiometabolic Index and Triglyceride-glucose index are robust predictive indicators closely associated with metabolic syndrome diagnosis, and waist circumference is identified as an excellent predictor. Integrating these variables into clinical practice holds the potential for enhancing early diagnosis and prevention of metabolic syndrome.

Active treatment of periodontal disease consists of plaque control by the patient, with root planing and surgery perfomed by the dental practitioner. Chlorhexidine rinse has been the most effective antiplaque agent available today and tetracycline has been the most favored antibiotics. Therefore, the purpose of this study was compared the different effect among groups(saline mouthrinse[group I], 0.125% chlorhexidine mouthrinse [groupII], and 0.125% chlorhexidine mouthrinse containing tetracycline[groupIII]) during the immediate post periodontal therapy. We assessed plaque index, gingival index, papillary bleediing index, gingival crevicular volume, periodontal attachment loss, and periodontal pocket depth in 3 sites per subject. The assessment was made at baseline. At 1 week after scaling, and at 2 weeks after curettage. All groups were clinically and statistically reduced plaque score, gingival score, papillary bleeding score, and gingival crevicular volume at 2 weeks after curettage. Group II was significantly reduced periodontal pocket depth.(P<0.05) At 1 week after scaling, al clinical index scores were reduced but not singificantly difference between the groups.(p>0.05) At 2 weeks after curettage, plaque score, gingival score and papillary bleeding score were significantly difference between the groups.(P<0.05) During the experimental period, gingiva was not damaged and stain of the tongue or teeth were not noted in all groups.
