The purpose of this study by examine the effect of visual neglect on hemiplegia motor recovery are showing trouble which can be raised by visual neglect and helping the patient's ADL and functional recovering. Among the patients who are being taken physical therapy in many other hospitals in Busan From February 1st 2002 to august 31st, we chose 20 patients as control group who did not have symptoms of visual neglect and 20 other patients who did have as case group. We used Albert's test and line bisection as visual neglect test, and MAS as motor recovery. The average age of the patient group is 51.55 and that of control is 44.9. The men's rate is higher than women' s in both groups. Although the rate of left hemiplegia is higher than right hemiplegia in case group, that of right hemiplegia is higher than left hemiplegia in control group. There is much lesion site of basal ganglia in case group. There is the most amount of transformation of MAS when visual neglect is shorter than 1.5centimeter. Each change of MAS point before and after therapy in case group and control group is revealed $6.5{\pm}4.37$ and $12.5{\pm}5.95$.

The objectives of the present study were to assess the early nutrition-related knowledge, eating behaviors of preschool children, the types of messages that their mothers give to them about nutrition and to analysis the interrelationships among these variables. The children of this study showed the uncooperative eating behaviors most frequently when they had breakfast and vegetables. In these cases the most frequent mother's messages given to the children was encourage eating some of each food. Children's eating problems as perceived by mothers were mainly low dietary intake and an unbalanced diet. The most frequent messages given to the children in the presentation of new foods were telling the child taste them and general nutrition about the new food. General topics in nutrition the mothers had discussed with their children were about nutrients, food groups, food transformations and food origins. Children whom mothers provided more information about these topics scored significantly higher on the concepts of food transformation, food origins and the total nutrition knowledge score. It is clear from this study that preschool children begin to learn about nutrition through these parental messages. Both parents and caretakers of young children should recognize the potential importance of these early interaction patterns.

We have investigated the solar activity variation with period shorter than 1000 days, through Fourier transformation of solar cycle 21 and 22 data. And real time predictions of the flare maximum intensity have been made by multilinear regression method to allow the use of multivariate vectors of sunspot groups or active region characteristics. In addition, we have examined the evolution of magnetic field and current density in active regions at times before and after flare occurrence, to check short term variability of solar activity. According to our results of calculation, solar activity changes with periods of 27.1, 28.0, 52.1, 156.3, 333.3 days for solar cycle 21 and of 26.5, 27.1, 28.9, 54.1, 154, 176.7, 384.6 days for solar cycle 22. Periodic components of about 27, 28, 53, 155 days are found simultaneously at all of two solar cycles. Finally, from our intensive analysis of solar activity data for three different terms of $1977\~1982,\; 1975\~1998,\;and\;1978\~1982$, we find out that our predictions coincide with observations at hit rate of $76\%,\;63\%$, 59 respectively.

Postal code is essential for improving efficiency of mail sorting. The Korean postal code, which is introduced in 1970 and had been reformed two times, has controversial issues because of changed postal environments such as modification of administrative districts and logistical transformation into a hub-and-spokes structure. In this study, we propose several improvement and evaluation methods in order to prepare an alternative plan of postal code system. After performing status analysis, we define the customers of postal code and analyze the requirements of them. The 6 proposed new postal code systems are based on each customer groups’ requirements. To evaluate the new systems, we develop several quantitative and qualitative indexes and make a survey of postal experts. Besides, we evaluate the influence of them to the postal environments including delivery sequence sorting process.

Purpose: This study was to assess the effect of surface and heat treatment on the bond strength of veneering ceramics to zirconia. Methods: The specimens were divided into 7 groups according to surface treatment and heat treatment conditions prior to porcelain application. ten specimens from each group were subjected to a 3-point flexural test. In addition the influence of surface and heat treatment on surface roughness values and phase transformation of zirconia was evaluated. Statistical analysis was performed with one-way ANOVA and post hoc Tukey's test. Results: Bond strength ranged from $20.67{\pm}3.13MPa$ to $32.69{\pm}4.52$. Bond strength of surface treatment group was lower than that of control group but only $Al_2O_3$ sandblasting group was significant difference. Bond strength of heat treatment group was higher than that of surface treatment group but there was no statistical significance. Conclusion: Bond strength of veneering ceramics to zirconia was affected by surface and heat treatment.

Successful Electronic Commerce(EC) requires not only a transformation of the supply chain but a redesign of organizational processes as well. Just as the organizations in a supply chain must cooperate with each other to achieve a collective goal, so too do the departments and groups that comprise an organization depend on each other to achieve the organization's goals. A lack of coordination at either of these levels can result in poor performance and high coordination costs. In addition, changes in inter-organizational dependencies can affect the dependencies within the affected organizations. The lack of coordination across two levels results in a transition gap in transforming the inter-organizational design to the intro-organizational design in EC deployments. The purpose of this research is to develop a modeling method for coordination, managing the linkage between inter- and intra-organizations in EC deployments. The method was applied to the EC development project of a cable TV home-shopping company. The coordination approach enabled us to manage dependencies among the coordination elements and identify the effect of a change on other elements, which became the basis for effective EC deployments. We will discuss the method and compare it with other dependency management methods.

This study uses expert analysis as a method of research to identify the value of hanok in rural landscapes. To do so, the study conducted the Delphi method and the AHP survey twice. First, the Delphi method was used on experts who have either studied rural landscape, regional development, hanok or have adequate knowledge in such areas, concerning the definiton of sustainable rural landscapes, the role of hanok in rural landscapes, the problems rural hanoks face, and the preservation and utilzation of rural hanok. Based on this, the AHP survey was conducted. The survey results showed that sustainable rural landscapes are 'landscapes in which the transformation proces coexists from traditonal to modern times.' The role of the rural hanok was shown to be 'the forming of landscapes that expres the historical flow of the vilage.' In the subsequent survey of rural landscapes, the order of import limitationance of hanok was regionality, historicity, harmoniousnes, eco-friendlines and familarity. However, a may be that this study is based on expert opinion which may not be regarded as universal. Therefore, future research on the basis of this study wil have to be conducted in a way to identify the value of hanok in rural landscapes from the perspective of various groups.

For smart defense innovation, the key is to apply state-of-the-art technologies of the Fourth Industrial Revolution to national defense. In order to apply state-of-the-art technology to the defense sector, we need to apply and develop technologies to analyze and respond to uncertain future operational environments. To this end, our military is investing a lot of time and effort. To understand future operational environment analysis and to apply and develop our military, we explored the perspectives of operational environment analysis in major countries and studied specific cases of U.S. troops with systematic analysis functions. The U.S. Army has established a cooperative system to analyze future operational environment under the leadership of the Education Command and operates the organization organically. It also utilizes the collective intelligence of expert groups in various fields by utilizing the MSC, and it is time for the Korean military to take the lead in keeping with the era of transformation. To that end, the organization of the U.S. Education Command should be benchmarked and the Korean Future Operation Environment Analysis Organization should be established and operated. Through this study, we have developed an understanding of the future operational environment analysis system of the U.S. Army and presented a plan to apply the ROK MND.

Newly graduated students are shown to constitute an important source of innovation within the architectural, engineering and construction (AEC) industry. In relation to digital technologies like BIM (Building Information Modelling) that is claimed to have a potential to transform the industry, newly graduated students may play a vital role in innovating with BIM. The paper aims to explore determinants for students perceived potential of BIM use (PPBU) and the role of the educational background. The aim will be achieved by analysing the results from a survey conducted among third- and fourth-year students in construction and civil engineering in Hong Kong, Sweden, and Thailand (n = 194). When the different groups are compared Swedish and Thai students perceive a significant higher PPBU than Hong Kong students. In a step-wise multiple regression analysis five predictors for PPBU were identified for Thai respectively Swedish students, and one predictor was identified for Hong Kong students. It is concluded that in the contemporary BIM-discourse it is claimed that BIM can/should transform the industry, and BIM is even seen as a disruptive technology, and newly graduated students will contribute to (digitally driven) innovation. However, from the predictors of PPBU, the question can raised if the awareness of the need for structural changes is lacking in the education, if students later in their working life should contribute to a BIM-induced transformation of the industry?
