The low-durability performance of concrete structure occurs by interactive deterioration factors. In particular, carbonation increased with its time elapse is known as the general manner of deterioration characteristics. Recently, the fundamental researches of the carbonation mechanism, besides method and technique for durability improvement of deteriorated structure are advanced actively. So in this paper, alkali-recovery and maintenance performance when the impregnating alkalization agents are used, are compared and examined quantitively with the basis of past proposed study. As a result, alkali-recovery performance be ensured by impregnating alkalization agent on the carbonated concrete which has low pH by accelerated carbonation test. And alkali maintenance performance was effected by the finishing materials on the alkali recovered concrete.

This study examines the effects of maternal behaviors and children's self-control ability on their subjective well-being. Data were collected from 416 fifth- and sixth-graders residing in Kwangju, Korea. Cronbach's ${\alpha}$ and the hierarchical regression analysis method were employed for a statistical analysis. According to the results of the hierarchical multiple regression analysis, children's self-control ability best explained their subjective well-being. For individual factors, motivational self-control had the greatest effect on subjective well-being, followed by behavioral self-control, cognitive self-control, the level of income, gender, and the employment status, in that order. The results for effects of maternal behaviors and children's self-control ability on children's subjective well-being highlight. The important roles played by the mother and the child's self-control ability in improving the child's subjective well-being. The study contributes to the literature by providing fundamental insights into children's higher quality of life.

A new approach for modelling and simulation of the cutting forces in end milling processes is presented. In this approach, the cutting forces in end milling are modelled based on a predictive machining theory, in which the machining characteristic factors are predicted from input data of fundamental workpiece material properties, tool geometry and cutting conditions. In the model, each tooth of a end milling cutter is divided into a number of slices along the cutter axis. The cutting action of each of the slices is modelled as an oblique cutting process. For the first slice of each tooth, it is modelled as oblique cutting with end cutting edge effect, whereas the cutting actions of other slices are modelled as oblique cutting without end cutting edge effect. The cutting forces in the oblique cutting processes are predicted using a predictive machining theory. The total cutting forces acting on the cutter is obtained as the sum of the forces at all the cutting slices of all the teeth. A Windows-based simulation system for the cutting forces in end milling is developed using the model. Experimental milling tests have been conducted to verify the simulation system.

In this paper, a new procedure is proposed to accomplish the primary plus secondary stress(P+Q) at the 'structural element' instead of 'transition element'. For the P+Q evaluation, the calculated stresses by FEA are linearized along a stress classification line to extract the stress category, then the stress intensity is calculated to compare with the $3S_{m}$ limit. Also, in this paper, the 'design by analysis' criteria, adopted fundamental concepts and a new approach to calculate $K_{e}$ factors are explained. The new procedure combined with 3-D FEA has been applied to motor operated valve in order to the over conservatism and the rack of margin. The evaluation results show a good applicability and can be utilized for fatigue life evaluation by using P+Q.

This study for‘Head Image’, which is affected by individual Image, is via fashion collection to analyze formative feature, fashion emotion and meaning structure of emotion and to inquire into correlation. I will offer fundamental data, which is can use Image making from the state of thing. First, to make charm and personal image, if we consider Head image well, it will very effective by the reason that personality and charm operate as important factors in fashion sensibility of Head Image. Second, we can know Head Image has more strong influence the part of emotion than fashion sensibility by showing that the sense of emotion is higher than this point of view of fashion sensibility in Head Image. Third, As a result of the correlation of fashion sensibility and emotion in Head Image, personal Head Image is effective to attract public gaze by causing negative emotion, and attractive Head Image is effective to give pleasant feeling by causing positive emotion. Forth, Avant-garde, Punk, Kitsch Image were estimated as the most personal things and Romantic, Ethnic Image were estimated as the most attractive things of the type of Head Image. Natural Image was estimated as the most feminine thing, and Elegant Image was estimated as the most mature thing. Fifth, when we look into the different appraisals between experts and amateurs about fashion sensibility and emotion of Head Image, a selection of experts are used to peculiar and strong Head Image, so amateurs respond it more sensitively and highly evaluate.

The purpose of this study is to analyze the effects of nuclear power plant workers and organizational characteristics on accidents, and seek the combination of policies for reducing accidents. For this purpose, it grasped, by using System Dynamics and Causal Loop Diagram, how various factors that cause accidents in nuclear plants are interrelated, and performed simulations after building simulation models. As a result of the analysis, first, the fundamental cause of safety accidents in nuclear power plants turned out to be the time constraint on the workload. Second, it turned out that as the workload of workers increases, physical and mental stresses increase, thereby increasing accidents due to errors and violations. Third, it turned out that as the levels of educational training and compliance with regulations and procedures are enhanced, accidents are reduced. Lastly, it turned out that as the combination of policies (reliance level + working environment + educational training + compliance with regulations and procedures) is increased, accidents are reduced. Especially, it turned out that if the combination of policies is increased by 30%, more than 10 cases of accidents are reduced.

For next generation global navigation satellite systems, new carrier frequencies in Ku/V band are expected to emerge as a promising alternative to the current frequency windows in L band as they get severely congestive. In the case of higher frequency bands, signal attenuation phenomenon through the atmosphere is significantly different from the L band signal propagation. In this paper, a fundamental investigation is carried out to explore the Ku/V band as a candidate frequency band for a new global satellite navigation carrier signal, wherein specific attention is given to the effects of the dominant attenuation factors through the tropospheric propagation path. For a specific application, a candidate orbit preliminarily designed for the Korean regional satellite navigation system is adapted. Simulation results summarize that the Ku band can provide a promising satellite navigation implementation considering the present satellite's power budget, while the V band still requires technical advances in satellite transceiver system implementations.

The Korea government has been pursuing various policies to find a new industrial growth engine based on ICT (Industry and Communication Technology). However, ICT industry recently faces a serious crisis due to a lack of fundamental competitiveness and capital and technological gap with other countries. Accordingly, it is necessary for ICT industry to recognize the rapidly changing competitive business environment and to establish appropriate value-based strategies. This paper analyses factors affecting value-based strategy in the Korean ICT industry using 10 years data set. The result shows that the value-based strategy in the Korean ICT companies has a significant influence on their financial performance. In addition, it is confirmed that the competition level in the industry has a significant moderating effect on this relationship. In addition, when the companies are categorized based on performance, it is confirmed that there is a significant difference in competition level and value-based strategy in each categories. The results of this paper are expected to suggest implications for the effective use of balanced value-based strategies in the ICT industry.
