The purposes of this study were 1) to classify wearing situation of male adolescents and 2) to classify self-image and CPI(Clothing Preference Image) of male adolescents and 3) to segment consumer group by self-image and to find the differences in self-image and CPI by situation among groups. For the data collection a questionnaire was distributed to male adolescents who were residents in Seoul and Taejeon. The statistics used for the data analysis were factor analysis, multiple dimensional scale, mean, percentage, peason-correlation, cluster analysis, one-way ANOVA, Duncan-test by the SPSSWIN program. The results of this study are as follows: 1) The self-image of male adolecents is categorized by seven factors; sophisticate and fashion conscious, active, practical and realistic, flank and pure, young-looking, feminine, and slender. Based on seven factors, the consumer group is categorized to five groups; practical and realistic Group1, young-looking and feminine Group2, characterless Group3, active Group4, sophisticate and flank Group5. 2) Wearing situations are divided into three categories; in downtown, in urban, at festival. In downtown, CPI are divided into six elements; ornamental, simplex, sexy, feminine, neat, young, and sophisticate. In urban, CPI are divided into five elements; ornamental, simple, sexy, feminine, young-looking, and sophisticate. At festival, CPI are divided into four elements; unique, simple, feminine, and formal. To conclude, the male adolescent consumers are categorized by self-image, and the different CPIs are sought by different wearing situations.

The chlorophyll-protein complexes were separated from thylakoid membranes of Spinach oleracea and Zoysia japonica by two gel Systems of LiDodSO4-PAGE and LiDodSo4/Urea- PAGE under nondenaturing conditions. Seven chlorophyll~protein complexes of CPI*, CPI, CPII*. CP47, CP43, CP29 and CPII were fractionated from both S,oleracea and Zjaponica by LiDodSO4-PAGE. CPI, CP47 and CP43 contained more chlorophyll a than chlorophyll b. The patterns of their absorption spectra at room temperature were similliar to that of chlorophyll a, judging by their UV-spedtroscopy. On the other hand, CPII* and CPII contained approximately equim-olar quantities of chlorophyll a and b. Additional five chlorophyll-protein complexes not separated in the LiDodSO4-PAGE system were electrophoretically isolated from both S, oleracea and Zjaponica by LiDodSO4/Urca-PAGE. The chlorophyll-protein complex just above LRCII $\alpha$in the gel appears CCII-RC separeted recently. 23 kDa and 20 kDa cho-protein complexes is probably LHCIa and LHCIb as judged from their molecular weight. Two novel chlorophyll~protein complexes designated "CPI7" and "CPI6" were fractionate by this gel system. Their molecular weights respectively. Although the stoichiometry of their components and their roles in thylakoid membranes are not apparant, It is thought that they are another kinds of LHCI.other kinds of LHCI.

과거 12년동안(2001~2012년)의 벼 등숙기간인 8~9월의 기상변화 특징은 기온이 높아지고 일조시간이 줄어드는 경향이었다. 이와 같은 벼 등숙기간의 고온과 일조시간의 부족은 벼 기준의 기후생산력지수(CPI)의 감소의 원인이었고, 감소의 정도는 벼 출수기가 빠를수록 더 크게 나타나는 것으로 분석되었다. 따라서, 안정적인 벼생산량을 확보하기 위해서는 벼 출수기를 늦추는 재배적인 조치가 필요할 것으로 판단되었다. 그리고, 과거 12년동안의 벼 수량의 변화는 특별한 경향을 나타내지는 않았으나, 벼 수량의 연간 변화는 CPI의 연간 변화와 유사한 패턴을 보였다. 특히, 출수기가 8월 11일 조건에서, 벼 수량에 대한 CPI의 일차함수는 전국 벼 수량 변이의 63%정도 설명하는 것으로 분석되었다.

Purpose: This study evaluated the predictive performance of a combination of self-report questionnaires, salivary hemoglobin levels, and age as a non-invasive screening method for periodontitis. Methods: The periodontitis status of 202 adults was examined using salivary hemoglobin levels, responses to 10 questions on a self-report questionnaire, and the Community Periodontal Index (CPI). The ability of those two variables and the combination thereof with age to predict the presence of CPI scores of 3-4 and 4 was assessed using logistic regression and receiver operating characteristic (ROC) curve analysis. Results: CPI scores of 3-4 and 4 were present among 79.7% and 46.5% of the sample, respectively. The area under the ROC curves (AUROCs) of salivary hemoglobin levels for predicting prevalence of CPI scores of 3-4 and 4 were 0.63 and 0.67, respectively (with sensitivity values of 71% and 60% and specificity values of 56% and 72%, respectively). Two distinct sets of five questions were associated with CPI scores of 3-4 and 4, with AUROCs of 0.73 and 0.71, sensitivity values of 76% and 66%, and specificity values of 63% and 69%. The combined model incorporating both variables and age showed the best predictive performance, with AUROCs of 0.78 and 0.76, sensitivity values of 71% and 65%, and specificity values of 68% and 77% for CPI scores of 3-4 and 4, respectively. Conclusions: The combination of salivary hemoglobin levels and self-report questionnaires was shown to be a valuable screening method for detecting periodontitis.

Purpose - Our previous study (Chang & Lee, 2023) presented observations on the recent changes in the year-on-year (YoY) Consumer Price Index (CPI) of the Republic of Korea (ROK) after the COVID-19 pandemic. The purpose of this article is to present an integrated analysis and interpretation of the recent changes in CPI and the Aggregate Import Price Index (IPI) by incorporating recent data, specifically data from September 2022 to December 2022. Design/methodology/approach - This study collected CPI (YoY) data in the ROK from January 2019 to December 2022 using e-National Indicator System provided by the ROK. Statistical analysis was employed to analyze the data. Findings - First, we confirm the extended results of the existing study by Chang and Lee (2023). Second, we demonstrate that the Aggregate IPI in ROK increased significantly in 2022 compared to 2021. We then provide an integrated interpretation on the significant increase in CPI and aggregate IPI in ROK, which complements Chang and Lee (2023) that limits their discussion to YoY CPI. Moreover, we show that the IPI of the semiconductor in ROK decreased significantly in 2022 compared to 2021. Research implications or Originality - Our results provide important insights into the recent changes in the CPI in the ROK. The results suggest that these changes can be partially attributed to various factors, such as the global supply chain disruptions resulting from the spread of the COVID-19 pandemic and the prolonged war between Russia and Ukraine, the side effect of quantitative easing by the US Federal Reserve, heat waves and droughts caused by climate change in ROK, a surge in demand following a gradual daily recovery, US-China trade conflict, etc. Our study shows statistically comprehensive results compared to the studies that limit their discussion to YoY average growth rate.

청렴도와 국가 경쟁력의 상관관계는 높은 것으로 알려져 있다. 그러나 국제투명성기구의 CPI 발표에 따르면, 국내 부패인식지수는 5점대로 부패한 상태로 나타났다. 그 중 우리나라의 부패 정도는 건설부문에서 가장 심화되고 있다고 조사되었다. 이처럼 우리 사회 부패사건의 25~54%를 차지하고 있는 건설부문의 투명성 제고가 필요한 시점이다. 국제투명성기구는 2010년 CPI 발표와 함께 CPI 산정에 활용된 원천자료를 공개하였다. 우리나라의 경우 6개 기관의 9개 자료가 활용되었다. PERC 2010 자료에서 우리나라 민간분야의 부패정도는 16개국 중 최하위인 매우 심각한 수준으로 평가되었다. 이러한 맥락에서 본 논문은 국제투명성기구 CPI 산정의 원천자료를 통하여 우리나라의 부패정도를 분석하였다. 분석된 문제점에서 건설산업의 영향을 파악하고 세계 각국의 반부패활동을 고찰하면서 국내 도입방안을 모색하였다. 결론적으로 건설산업의 투명성 제고 방안은 건설산업의 구조적 요인 개선, 부패에 대한 처벌의 실효성 제고, 건설투명성 관리 강화 등 세 가지로 정리된다.

Objectives: The purpose of the study was to examine the association between diabetes mellitus and community periodontal index in Korean adults. Methods: The study populations were recruited by the Fifth Korea National Health and Nutrition Examination Survey. Study subjects were 10,411 who were examined oral examination, blood test, and aged over 19 years. Using multiple logistic regression analyses, the variables were adjusted for gender, age, household income, family history of diabetes, body mess index, smoking habit, and frequency of tooth brushing. Periodontal tissue examination of the subjects was performed and scored by Community periodontal index(CPI). Using probe, six teeth were examined for hemorrhage, plaque, and pocket depth and classified into $CPI_0$, $CPI_1$, $CPI_2$, $CPI_3$ and $CPI_4$. Healthy periodontal groups($CPI_{0-2}$) and periodontal disease groups($CPI_{3-4}$) were divided by the periodontal disease status. The definition of diabetes mellitus(DM) was decided by the diagnosis by the doctors and fasting blood sugar level. Those who were diagnosed as DM were included in DM group. The DM variables included normal blood sugar level, increased fasting blood sugar level, and DM blood sugar level. The DM variables were compared to periodontal disease blood sugar level and analyzed. Results: The periodontitis prevalence rate was 23.2%. Those who had diabetes mellitus accounted for 5.5% of the subjects. Those who had impaired fasting glucose accounted for 17.7% and 7.9% of subjects were diabetes mellitus by blood test. In the confirmed diabetes group by doctor, the periodontitis prevalence rate was significantly higher than the non-diabetic group. Diabetic group by blood test had the highest prevalence rate of periodontitis than those who had impaired fasting glucose group or normal group. After adjusting for gender, age, household income, family history of diabetes, body mass index, smoking habit, and frequency of tooth brushing, the risk of periodontitis in diagnosed diabetes mellitus was 1.57 times(95% CI; 1.27-1.94) higher than the normal group. In impaired fasting glucose group and diabetes mellitus group by blood test, the risk of periodontitis was 1.11 times(95% CI; 0.95-1.30) and 1.45 times(95% CI; 1.45-2.12) higher, respectively. Conclusions: There was a significant relationship between diabetes mellitus and periodontitis in Korean adults. These results suggest that diabetes mellitus is a risk factor for periodontitis.

철도궤도 하부구조물의 유지, 보수 및 과다설계에 따른 비용을 최소화하기 위하여 궤도 하부구조물의 강도 및 강성특성에 대한 정확한 평가는 필수적이다. 본 연구에서는 궤도 하부구조물의 상태를 평가하기 위한 콘 관입기(CPI)를 개발하였으며, 적용성 검증을 위하여 실내실험과 현장실험을 수행하였다. CPI를 이용한 철도궤도 하부구조물 평가의 결과로서 획득되는 결과는 동적 콘관입지수(DCPI), 원추관입저항력($q_c$), 마찰저항력($f_s$) 및 마찰력비(Fr)이다. 실험결과, 실내실험의 경우 도상자갈층에서 획득한 동적 콘 관입지수와 상부노반층에서 획득한 원추관입저항력, 마찰저항력 및 마찰비는 조성한 시료에 대하여 신뢰할 만한 결과를 보였다. 현장실험의 경우 도상자갈층의 경계면을 명확히 구분해 내었으며, 상부노반층의 불연속면을 감지하였다. 본 연구에서 개발된 CPI는 동적 관입과 정적 관입 방법을 이용함으로써 궤도 하부구조물 평가에 유용한 방법이 될 것이라 기대된다.

Background: The goal of this in vitro study was to investigate the effect of lipid emulsion on vasodilation caused by toxic doses of bupivacaine and mepivacaine during contraction induced by a protein kinase C (PKC) activator, phorbol 12,13-dibutyrate (PDBu), in an isolated endothelium-denuded rat aorta. Methods: The effects of lipid emulsion on the dose-response curves induced by bupivacaine or mepivacaine in an isolated aorta precontracted with PDBu were assessed. In addition, the effects of bupivacaine on the increased intracellular calcium concentration ($[Ca^{2+}]_i$) and contraction induced by PDBu were investigated using fura-2 loaded aortic strips. Further, the effects of bupivacaine, the PKC inhibitor GF109203X and lipid emulsion, alone or in combination, on PDBu-induced PKC and phosphorylation-dependent inhibitory protein of myosin phosphatase (CPI-17) phosphorylation in rat aortic vascular smooth muscle cells (VSMCs) was examined by western blotting. Results: Lipid emulsion attenuated the vasodilation induced by bupivacaine, whereas it had no effect on that induced by mepivacaine. Lipid emulsion had no effect on PDBu-induced contraction. The magnitude of bupivacaine-induced vasodilation was higher than that of the bupivacaine-induced decrease in $[Ca^{2+}]_i$. PDBu promoted PKC and CPI-17 phosphorylation in aortic VSMCs. Bupivacaine and GF109203X attenuated PDBu-induced PKC and CPI-17 phosphorylation, whereas lipid emulsion attenuated bupivacaine-mediated inhibition of PDBu-induced PKC and CPI-17 phosphorylation. Conclusions: These results suggest that lipid emulsion attenuates the vasodilation induced by a toxic dose of bupivacaine via inhibition of bupivacaine-induced PKC and CPI-17 dephosphorylation. This lipid emulsion-mediated inhibition of vasodilation may be partly associated with the lipid solubility of local anesthetics.
