Initial evaluation of intrafraction motion using frameless CyberKnife VSI system
AbstractAimTo analyze intrafraction movement in patients undergoing frameless robotic radiosurgery and evaluate the influence of image acquisition frequency on global accuracy.BackgroundStereotactic radiosurgery requires high spatial accuracy in dose delivery. In conventional radiosurgery, a rigid frame is used to guarantee a correct target alignment and no subsequent movement. Frameless radiosurgery with thermoplastic mask for immobilization cannot completely eliminate intrafraction patient movement. In such cases, it is necessary to evaluate its influence on global treatment accuracy.Materials and methodsWe analyzed the intrafraction motion of the first 15 patients undergoing intracranial radiosurgery (39 fractions) with the CyberKnife VSI system at our institution. Patient position was measured at a 15–90-s interval and was used to estimate intrafraction patient movement.ResultsWith our acquisition image protocol and immobilization device, the 99% displacement error was lower than 0.85mm. The systematic movement components were lower than 0.05mm and the random component was lower than 0.3mm in the 3 translational axes. Clear linear time dependence was found in the random component.ConclusionsSelection of the X-ray image acquisition time is necessary to meet the accuracy required for radiosurgery procedures with the CyberKnife VSI system. We verified that our image acquisition protocol met the 1-mm criterion
Employment productivity and wages in the Philippine labor market : an analysis of trends and policies
The present government's concern is aimed towards poverty
alleviation, productive employment generation, income
redistribution and sustained economic growth. Given these
development goals, issues concerning employment, wages and
productivity which have gained prominence through the years
should be dealt with. Rising levels of unemployment and
underemployment along with declining productivity and real wages
continue to plague the economy. Likewise, the balance of
payments problems and the increasing indebtedness further
aggravate the worsening economic condition. These major problems
began to attract much attention for there arose dissatisfaction
among the populace with the upsurge in the incidence of poverty
and the occurrence of other related problems.
With the task of finding solutions to these problems, the
government implemented policies and initiated a structural reform
program. The purpose of the .present study is twofold. First,
the nature of the abovementioned problems is studied by looking
at the labor market conditions. Specifically, an analysis of the
trends in employment, wages and productivity, and a comprehensive
historical account of how policies and policy changes affected
them directly and indirectly, are presented. Moreover, the
impacts of policies adopted by the government in the 1980s on
employment, wages and productivity are assessed qualitatively.
Policy recommendations are drawn based on the findings of the
study.
Secondly, the employment impact of the various structural
adjustment measures adopted in the 1980s is re-examined within a
general equilibrium framework. Specifically, the study provides
estimates of the employment and wage effects of the structural
adjustment program based on simulation experiments using the
PIDS-NEDA (1987 version) macroeconometric models and Habito's
(1986) computable general equilibrium model of the Philippine
economy. Based on these, policy recommendations and new
directions for future research in the area are provided.
Part I of this study discusses the recent trends in
employment, unemployment, underemployment, wages and
productivity. It was observed that employment has generally
increased over the period 1970-87 with a few years exhibiting
slight declines. It was also observed that more than 50 percent
of total employment was engaged in agriculture while the share of
agriculture to total employment showed an apparent tendency to
decline. The structural shift has been from agriculture to
services, instead of agriculture to industrial sector.
Unemployment rates in the country were high especially during the
1980s. Likewise, underemployment rates were also rapidly rising.
Labor productivity roughly measured by output per worker has
increased from 1961 to 1980 but declined thereafter until 1986 afterwhich a slight increase was observed in 1987. Nominal
agricultural and nonagricultural wages has been increasing
through the years. However, real wages in both sectors declined.
A review of the past and present policies showed that the
industrialization policies implemented during the post-war period
generally increased output and investments but their inherent
capital bias resulted in the low rate of labor absorption. The
manufacturing sector failed to generate enough jobs necessary to
absorb the increasing labor force. This was due to factors like
the limitations in the domestic market for output of import
substituting firms, and the misallocation of investible funds to
high cost industries as a result of incentives and short-sighted
labor legislation which raised labor costs and discouraged
employment. In addition , the adoption of an outward-looking
strategy like export promotion is hindered by the lack of
reciprocal response in the international setting due to
increasing protectionism and stagnation among developed
economies.
In search for policies which can increase labor absorption,
the following points were made based on the analysis. First,
what is called for is a system of taxation and protection which
is nonfactor price distortive. Secondly, economic growth and
employment generation can be accelerated with a firmer commitment
on the part of the authorities in implementing the structural
reforms. And lastly, the outward-looking strategy is worth
pursuing giving emphasis to light manufacturing industries which
showed resiliency to the impact of the economic crisis as
evidenced by its ability to maintain relatively high levels of
sales and small levels of labor displacement during the crisis
years.
Part II provides a quantitative assessment of the impact of
structural adjustment measures on employment and wages. Using
the PIDS-NEDA macroeconometric models, three counterfactual
experiment related to structural adjustment policy reform were
conducted to appraise their employment effect for 1980 to 1990.
Firstly, simulation results showed that the tariff reform program
(TRP) has a positive effect on output, employment, exports and
prices. Secondly, removal of export taxes on all products except
logs in 1986 has a small positive effect on output and total
employment except in 1989 and 1990. The policy has favorable
influence on current account balance by effecting an increase in
exports. Thirdly, an evaluation of the financial liberalization
program using the PIDS-NEDA model was found not to be feasible
given the shortcomings of the present version of the model.
Using Habito's computable general equilibrium model, two
simulations were. done. First, the estimates showed that TRP
increased total output and average wage implying positive effect
on the labor market. The policy increased the relative price of
nontradables while it decreased relatively price of importables. It also decreased average wage in agriculture and manufacturing
while it increased that of nontradables. TRP was found to favor
middle income groups. Second, BOI incentives decreased total
output, average wage and total employment. It has a regressive
impact on real income across household group. The shift to a
flexible exchange' rate regime has a positive effect on output and
prices. Labor is reallocated into export and import substituting
sector away from nontradables
