The objective of this study is to analyze the impact of conservative financial reporting on investment during uncertainty. It was assumed that during uncertainty conservative financial reporting can play an important role to improve investment decision-making. For our analysis, data sets from 2005-2020 of nonfinancial companies are used. To measure the impact of conservative financial reporting in the non-financial sector of Pakistan, Khan and Watts' (2009) model is applied. "Prospector" and "Defender" Business strategy is applied for measuring firm-level uncertainty. Investment is measured by adding the change in fixed assets (property, plant, and equipment). To check the robustness of conservative financial reporting, Givoly and Hayn's (2000) Negative Accruals measure is applied. To measure the robustness of uncertainty, environmental scanning and alertness technique is applied. According to environmental scanning and alertness technique, companies are divided into two groups named 'inert' and 'alert'. 'Inert' are those firms that are not scanning their environment, and 'alert' are those firms who continuously analyze their environment. The empirical estimations support our hypothesis. The empirical findings provide the proof that in the wake of uncertainty conservative financial reporting may facilitate to take optimal investment decisions in the developing economy of Pakistan. Our results provide critical and practical implications for investors, researchers, and standard setters.

This study examines whether accounting conservatism can support real earnings management by reducing accrual earnings management techniques. The net impact of conservative reporting on earnings management is also analyzed. It is assumed that moderating the role of conservative financial reporting during uncertainty can mitigate earnings management practices. For our analysis, 5354 firm-year observations for the period 2007-2020 of nonfinancial companies listed on the Pakistan Stock Exchange are applied. To measure conservatism in the non-financial sector of Pakistan, Khan and Watts' (2009) model is used to provide evidence that conservatism is a way to restrict earnings management during uncertainty. "Prospector" and "Defender" Business strategy is applied for measuring firm-level uncertainty. To measure accrual earnings management Modified Jones (1995) model and Dechow and Dichev (2002) approach and Kasznik (1999) model are applied, and for real earnings management Roychowdhury model is applied which follows three approaches to measure real earnings management i.e. cash flow manipulation, Overproduction, and discretionary expenses. The estimations support our hypothesis by providing statistically significant proof that conservative financial reporting in a developing economy like Pakistan may be used to overcome the net impact of earnings management during uncertainty. Our results provide critical and practical implications for investors, researchers, and standard setters.

The purpose of this in vitro study was to measure and compare the in vitro micro shear bond strengths of the following dentin bonding systems to different dentin surfaces under simulated pulpal pressure. Occlusal surfaces of 180 extracted human molars were prepared to expose the dentin surface in perpendicular to axis of tooth. Teeth were randomly assigned to 3 equal groups and subdivided into 4 equal groups. 4 adhesive systems(All Bond 2, SEbond, AdheSE, Prompt L-Pop) were used in this study.(omitted)

수복용 복합레진이 도입된 이후 많은 물성의 향상이 이루어졌으나 중합수축은 아직 해결되지 않은 주요 단점으로 남아있다. 중합수축이 적은 복합레진을 만들기 위한 많은 노력이 이루어져 최근에 silorane 기질의 저수축 복합레진이 개발되었고, 정밀하게 중합수축을 측정하기 위한 여러 방법들이 시도되었다. 본 연구에서는 컴퓨터 시각(computer vision)을 이용하여 시편에 직접 접촉하지 않으며 광중합 복합레진의 선형중합수축을 측정할 수 있는 입자 추적 시스템을 개발하였고 이를 이용하여 silorane (P90) 및 methacrylate (Z250과 Z350) 기질의 광중합 복합레진의 중합수축 거동을 측정하여 다음과 같은 결론을 얻었다. 1. 복합레진의 선형중합수축은 0.33-1.41% 였으며 silorane기질의 복합레진인 P90이 가장 낮았고 Z250, Z350의 순으로 증가하였다. 2. 본 장비는 선형중합수축을 시편의 형태에 민감하지 않고 복잡한 과정없이 실시간으로 측정할 수 있었다.

Purpose: The purpose of this study is to identify and to investigate the nursing organizational culture. Method: A descriptive correlational study was conducted with convenience sample of 448 staff nurses who were working for six general hospitals located in Seoul, Province of Gyeonggi and Province of Chung-cheong. The period of data collection took over 5 months between August and December. Organization Culture Questionnaire developed by Lee (2001) were used to measure nursing organizational culture. Collected data were analysed on SPSS Win 12.0. Result: The meta culture of the nursing organizations was the conservative culture. The cultural pattern of nursing organizations was classified into three patterns which were conservative-dominant culture, symmetric culture and innovative-task culture. Conclusions: The meta culture of the nursing organizations was the conservative culture. But conservative culture decreased nurses' outcomes. Therefore the nurse manager should develop a symmetric organizational culture including four types of culture than dominant culture of one type.

A new error measure for a static finite element analysis is proposed. This error measure is a modification to the Zienkiewicz and Zhu energy norm. The new error estimator is a global error measure for the analysis and is independent of finite element model size and internal stresses, hence it is readily transportable to other error calculations. It is shown in this paper the the new error estimator also produces conservative error measurements, making it a suitable procedure to adopt in commerical packages.

The purpose of this study was to measure the free flow of the unpolymerized resin by its weight for 10 minutes by one minute interval, and to measure the dimensional change of composite resins during the irradiation of visible light(Quich light VL-l Kuraray Japan) using visible leser displacement meter(LC-2210 Kerence Japan). The unpolymerized resin was cured by the visible light for 40 seconds, the dimensional change was measured at the begining of irradiation for 5 minutes. The results were as follows : 1. In free flow LFI was the largest, BLI was the smallest at $23^{\circ}C$ and CFP was the largest, and BL was the smallest at $37^{\circ}C$. 2. In dimensional change CFI, LFP, LEI and CFP was excessively contracted flow the begining of irradiation until 15 seconds but BLI and BL was excessively contracted until 30 seconds BL and BLI in dimensional change was much larger than LFI and CFP.

The purpose of this study was to measure roughness on the polished surfaces of composite resin, and was to observe the polished surfaces under Scanning Electron Microscope. The surface roughness tester (Surfcom 700A Semitsu Profilometer Tokyo. Japan) was used to measure roughness of polished surfaces. In this study, 4 brands of composite resin were examined, Pyrofil bond anterior Bell-Feel anterior Clearfil F II and Microrest A.P. White point, Silicone point, Super snap, and Sof-Lex medium disc as cutting instrument, and celluloid matrix were used. The results obtained were as follows. 1) The celluloid matrix produced the smoothest surfaces. 2) Microrest composite resin had smoother surface than any other composite resins after polishing. 3) The values of surface roughness made by White point, Silicon point and Super snap were similar. 4) The surfaces made by Sof-Lex medium disc was smoother than the surfaces made by any other polishing instruments.

Purpose: The aim of this study was to describe the effects of conservative treatment intervention for individual with scoliosis. Methods: Studies were selected through a search of computerized databases of the literature (KERIS, 2000-2010) using "early detection", "conservative treatment", "exercise", "physical therapy", "manipulation", "chiropractic", "therapy", "taping" and "orthosis" as keywords. Selected articles were classified by research design and statistical methods. Results: Application of the search strategy to the KERIS databases resulted in 132 articles. Based on titles and abstracts, 17 studies were selected, excluding articles of overlapping study, surgery, pharmacologic therapy and no correcting aim under conservative treatment. Among the 17 selected studies, the majorityof study design consisted of one group pretest-posttest design and additionally most of these studies were paired (or independent) t-test. The most frequently used intervention was exercise therapy. Conclusion: All articles showed that interventions were effective. Thus, early detection of scoliosis may be connected participation of early conservative treatment. It is important to reduce prevalence of scoliosis in adolescents using regular evaluation as an effective measure.
