Triple-negative breast cancers constitute about 15% of all cases, but despite their higher response to neoadjuvant chemotherapy, the tumors are very aggressive and associated with a poor prognosis as well as a higher risk of early recurrence. This study was retrospectively performed on 101 patients with stage II and III invasive breast cancer who received 6-8 cycles of neo-adjuvant chemotherapy. Out of the total, 23 were in the triple negative breast cancer subgroup. Nuclear Ki-67 expression in both the large cohort group (n=101) and triple negative breast cancer subgroup (n=23) and its relation to the pathological response were evaluated. The purpose of the study was to identify the predictive value of nuclear protein Ki-67 expression among patients with invasive breast cancers, involving the triple negative breast cancer subgroup, treated with neoadjuvant chemotherapy in correlation to the rate of pathological complete response. The proliferation marker Ki-67 expression was highest in the triple negative breast cancer subgroup. No appreciable difference in the rate of Ki-67 expression in triple negative breast cancer subgroup using either a cutoff of 14% or 35%. Triple negative breast cancer subgroup showed lower rates of pathological complete response. Achievement of pathological complete response was significantly correlated with smaller tumor size and higher Ki-67 expression. The majority of triple negative breast cancer cases achieved pathological partial response. The study concluded that Ki-67 is a useful tool to predict chemosensitivity in the setting of neoadjuvant chemotherapy for invasive breast cancer but not for the triple negative breast cancer subgroup.

목적: 국가별 감염병 대응 역량을 분석하여 이를 바탕으로 우리나라의 감염병 관리 대응에 대한 개선점을 찾아보고자 한다. 방법: 본 연구에서는 첫 번째로 2022년 WHO가 공개한 전 세계 96개국 SPAR 점수로 코로나19 감염병 대응 역량을 국가별로 분석하였다. 둘째, Our World in Data와 글로벌보건안보지수(GHSI)를 활용하여 각국의 구체적인 코로나19 방역 성과를 분석하였다. 결과: 첫째, 2021년 1월 24일의 방역강도 지수는 동남아시아 지부 방역이 67.6으로 가장 높아 강한 방역대책을 가지고 있었고, 아프리카 지부는 44.5로 가장 낮았다. 2022년 12월 31일의 방역강도 지수는 유럽이 11.6으로 대폭 낮아졌다. 둘째, SPAR 지표가 인구 백만명당 총환자수에 미친 영향 요인은 국가 실험실(C4)로 p=.027이고, 인구 백만명당 총사망수에 미친 영향 요인은 감염 예방과 관리(C9) p=.005, 위험 의사소통 및 지역사회 참여(C10) p=.040이었다. 1인당 GDP의 영향 요인은 감염 예방과 관리(C9) p=.009이고, GHSI에 미친 영향 요인은 감염 예방과 관리(C9) p=.002이었다. 결론: 이상의 연구결과로 감염병 역량 정도를 각 국가가 자체평가한 결과인 SPAR가 코로나19의 누적 환자수를 낮추거나 방역강도를 결정하는 것과 연관성을 발견하기 어려웠지만 사망율과 GHSI, 국민소득 등과는 일정 부분 영향을 받은 것으로 판단이 된다. 향후 우리나라의 감염병 관리 대응에 대한 개선점은 향후 미지의 신종감염병이 발생했을 때를 대비하여 JEE 혹은 GHSI 등과 같은 보다 과학적이고 신뢰성 높은 데이터를 중심으로 대응역량을 분석하여 사회·경제적 비용 감소 효과를 절감할 수 있는 방역대책 수립이 필요하다. 이를 기초로 공중보건학적 국가 위기에 대응하여 전문가 그룹을 중심으로 한 콘트롤타워의 주도적인 의사결정과 효과적 보건 의사소통도 요구된다.

This study assessed the reliability of the agricultural water supply based on future climate change scenarios, and suggested plans to improve the reliability in order to promote the adaptability of irrigation water in agricultural reservoirs to climate change. The assessment of agricultural water supply reliability was performed on reservoirs which had a lower water quantity than their design basis and which had recently been subject to drought. In other words, from the irrigation districts of main intake works among the reservoirs managed by the Korea Rural Community Corporation, 1~2 districts in each province-that is, a total of 13 districts -that were recently designated as a district for securing agricultural water (drought prevention district) were selected. Climate change scenarios were applied to the selected districts to analyze their future water supply reliability compared to the current level. All districts selected showed a drought frequency of 4 years or shorter, which demonstrated the need to establish climate change response plans. As plans for responding to climate change, a plan that utilizes supplemental intake works to reduce the area of the irrigation districts of main intake works, and another one that increases the capacity of main intake works were adopted to reanalyze their water supply reliability. When the area of the irrigation districts of main intake works was reduced by about 30~40%, the drought frequency dropped to more than 10 years, securing the reliability of water supply. To secure the reliability by increasing the capacity of main intake works, it was calculated that about 19,000~2,400,000 tons need to be added to each reservoir. In addition, climate change response plans were suggested to improve the reliability of the water supply in each district based on the results of economic analysis.

In this work, a simple quasi 3-D parabolic shear deformation theory is developed to examine the bending response of antisymmetric cross-ply laminated composite plates under different types of mechanical loading. The main feature of this theory is that, in addition to including the transverse shear deformation and thickness stretching effects, it has only five-unknown variables in the displacement field modeling like Mindlin's theory (FSDT), yet satisfies the zero shear stress conditions on the top and bottom surfaces of the plate without requiring a shear correction factor. The static version of principle of virtual work was employed to derive the governing equations, while the bending problem for simply supported antisymmetric cross-ply laminated plates was solved by a Navier-type closed-form solution procedure. The adequacy of the proposed model is handled by considering the impact of side-to-thickness ratio on bending response of plate through several illustrative examples. Comparison of the obtained numerical results with the other shear deformation theories leads to the conclusion that the present model is more accurate and efficient in predicting the displacements and stresses of laminated composite plates.

The Cancer Control Act in Japan became effective in 2006. In Ibaraki, Toyama, and Hyogo prefectures, the Cancer Control Promoter (CCP) plan was created to strengthen partnerships for cancer prevention. This study aimed to examine the curre nt status of CCP utilization and analyze relationships with intersectoral collaboration, both within the government and with outside partners. In 2008, we mailed questionnaires to 100 administrators responsible for disease prevention and health promotion in municipal governments of the three prefectures. Ninety-one administrators responded (response rate, 91.0%). We analyzed responses to questions regarding whether or not the municipalities had used CCPs. Items assessing intersectoral collaboration examined municipality characteristics and relationships with outside partners and sectors specializing in areas other than community health. Among 90 administrators with valid data, 33 municipalities (36.7%) used CCPs while 57 (63.3%) did not. The Fisher's exact test revealed that intersectoral collaboration for using CCPs was associated with communication with all of the municipal government sectors not related to health. The present study indicated that CCPs were not consistently used in municipalities. However, we found that intersectoral collaborations, especially within the local government, may be related to the practical use of CCPs. This, in turn, may result in effective cancer control and prevention, as well as improvement in community health.

The medical insurance system has been adopted in 1989. Since then, the utilization of medical care services has increased rapidly. It appears that the medical institution needs more nursing manpower such as nurses and nurse aides to meet an increased demand for medical care for the residents. However, the medical care clinics run by a medical practitioners has a more shortage of nursing manpower than hospitals. The purpose of this survey was to analyze the current employment status and to obtain an opinion on the improvement of utilization such as recruitment and retention of nursing manpower. The questionnaire sent to the private physician and the response rate was 28.7% ; 87 out of 300 physicians. 82.6% of the respondents employed nurses aides rather than nurses and an average number of employees per clinic was 2.5 persons. Most physicians had difficulties in recruiting nursing manpower. It took more than one month for replacement on average, therefore, they were suffering from giving good continual care for the patient and also high resignation of nursing personnel. The low wage, long working hours, hard work and lack of incentives are the biggest reasons for the difficulty in recruiting and retaining of the nursing personnel obtained for the clinics survey. The above mentioned problems would be solved in the near future by changing those difficulties. In the meantime, the private physicians are marking an effort to retain the nursing personnel by keeping a relationship of the private physician's cooperatives.

The purpose of this study was to investigate the relationships of early childhood teachers' communication ability, teacher efficacy, and organizational effectiveness of child care centers. The subjects of this study were 397 teachers working at child care centers. The results of this study were as follows. First, differences in the organization effectiveness of child care centers were detected according to teachers' age, career, type of child care center where they were affiliated, and marriage status. Second, the relative effects of the teachers' communication ability and teacher efficacy on the organizational effectiveness of early-childhood educational institutions differed significantly according to each sub-factor; teachers' communication ability's sub-factors - response, analysis, and evaluation - and teacher efficacy's sub-factors - general efficacy and personal efficacy - had partial effects on the organizational effectiveness of child care centers. Of these, personal efficacy had the greatest effects on all sub-factors of organizational effectiveness. This study is significant since it identifies the variables that could affect the organizational effectiveness of child care centers.

The current study aims to identify factors associated with private tutoring of college students in Korea. For this purpose, this study used the Korean Education and Employment Panel survey, which contains items regarding whether or not college students receive private tutoring as well as the monthly costs of private lessons. The current study focuses on private English lessons due to the very low response rates of other types of private tutoring. For the analysis, the 5th wave of KEEP collected in 2008 was selected, and a Heckman selection model was employed, including three categories of variables: individual, school, and parent/household factors. The results have revealed that for the selection model (receiving private English tutoring or not), having received private lessons in high school, gender, and level of satisfaction regarding the respondent's current university were significant. In terms of the outcome model (cost for private English tutoring in college), university admission type (rolling vs. regular), living with parents, school type (4-yr university vs. others), being in debt to cover private lesson fees in high school, and monthly household income had significant effects. This article also discusses the results and implications for future research and policy makers.
