Examinations and analysis were done to understand the digital reference services of the Teaching & Learning Aid Centers under 16 metropolitan city and provincial offices of education. The data used were collected from July 3. 2006 to July 15. 2006 by the direct contacts on their main homepages and recording the question and answer transcripts. It was proven that 13 of the 16 Teaching & Learning Aid Centers have done the reference services. In this study, several characteristics-whether the digital reference service was done or not, interface access level, its title, its communication tool, reference question number, reference question style, answer rate, etc-were analyzed. Tips for the future development were provided on the basis of the inadequacies and other findings revealed through this study.

This paper aims to find out the current state of early English education in the world(including Korea) and to suggest its more desirable direction, with special reference to TEFL in elementary schools of Korea. In fact English teaching in elementary schools of Korea has been put into practice as an extracurricular activity since 1982. But in 1995 the Ministry of Education proclaimed a policy to establish a TEFL program as the regular course in elementary schools of Korea since 1997. In this connection, the writer surveyed several kinds of theories about early English education to verify the necessity and validity of Korea's elementary school English education. The logical result from these theories is that younger children are better equipped to learn foreign languages with efficiency than older children or adults. However, as most studies are based on logical inferences rather than on direct observation or experimental evidence, we are not sure that those theories are right. In this view, the writer put stress on the preparation of educational environments to establish a more desirable direction of early English education in Korea, since Korea's elementary school English education will be practiced under EFL environment, not ESL environment. The writer also pointed out some problems of educational finances, the curriculum development process and its content, teaching materials(textbooks and tapes), English teachers, teaching methods, evaluation, educational facilities. This paper concludes that we have to try to solve these problems to succeed in a TEFL program in elementary schools of Korea and suggests several things for a more desirable direction of Korea's elementary school English education.

In this paper, we developed an intuitive teaching and control system that directly teaches a task by holding the tip of a robotic arm and moving it to a desired position. The developed system consists of a 6-axis force sensor that measures position and attitude forces at the tip of the robot arm, an algorithm for generating robot arm joint speed control commands based on the measured forces at the tip, and a self-made 6-axis robot arm and control system. The six-dimensional force/torque of the position posture of the robot arm operator steering the handler is detected by the force sensor attached to the handler at the leading edge and converted into velocity commands at the leading edge to control the 7-axis robot arm. The verification of the research method was carried out with a self-made 7-axis robot, and it was confirmed that the proposed force sensor-based robot end-of-arm control method operates successfully through experiments by teaching the operator to adjust the handler.

This study has made use of the work sampling for work analysis and productivity of food service institutions centering on 3 general hospitals of 400∼600 beds and centralized service system in Seoul. The results were as flollows; 1. In the mean work percent of dietitians: The indirect work functions marked the highest, as it was 22.0% for the direct work functions, 57.4% for the indirect work functions and 20.6% for the delays. Among the indirect work functions, the decreasing order was original clerical (38.1%), instruction or teaching (8.5%), conference or interview (8.5%), and appraisal (2.3%). 2. In the mean work percent of clerical personnels: The direct work functions (67.2%) marked the highest. Among those, routine clerical was 64.3%, and receiving was 2.8%. 3. In the mean work percent of workers: The direct work functions (77.4%) marked the highest. Among those, the decreasing order was service (24.7%), cooking (22.5%), cleaning (18.2%), and transportation (10.3%). 4. Work percent per labor hour: Dietitians usually continued to work even during the lunch time. In case of clerical personnel working in turn, work percent was high even during the lunch time, however in the other case, it was very low. It was shown that the workers had lunch and break time after every their service. 5. The number of meals served per labor hour were 6.3 meals, and labor time spent per served meal 9.8 minutes.

The purpose of this study is to investigate children's informal knowledge of the fractional multiplication and to develop a teaching material connecting the informal and the formal knowledge. Six lessons of the pre-teaching material are developed based on literature reviews and administered to the 7 students of the 4th grade in an elementary school. It is shown in these teaching experiments that children's informal knowledge of the fractional multiplication are the direct modeling of using diagram, mathematical thought by informal language, and the representation with operational expression. Further, teaching and learning methods of formalizing children's informal knowledge are obtained as follows. First, the informal knowledge of the repeated sum of the same numbers might be used in (fractional number)$\times$((natural number) and the repeated sum could be expressed simply as in the multiplication of the natural numbers. Second, the semantic meaning of multiplication operator should be understood in (natural number)$\times$((fractional number). Third, the repartitioned units by multiplier have to be recognized as a new units in (unit fractional number)$\times$((unit fractional number). Fourth, the partitioned units should be reconceptualized and the case of disjoint between the denominator in multiplier and the numerator in multiplicand have to be formalized first in (proper fractional number)$\times$(proper fractional number). The above teaching and learning methods are melted in the teaching meterial which is made with corrections and revisions of the pre-teaching meterial.

This study was conducted to assess the effects of nutrition label education in children. The students of three randomly selected sixth-grade classes at an elementary school participated, were classified into a control group, an indirect (written message to parents) education group, and a direct (teaching children) education group. Nutrition label education was conducted in the latter two groups but not in the control group. There were no significant differences between pretest and posttest scores for nutrition knowledge or in the dietary attitudes of the control group and indirect education group. Improvements in test scores for nutrition knowledge and dietary attitudes were observed only in the direct education group. There were significant positive changes in the indirect and direct education groups, such as selecting snacks (cookies) by considering the fat content. Moreover, after the lessons, the percentage of children who chose white milk (regular milk, calcium-enriched milk, and low-fat milk) significantly increased in the direct education group. This study suggests that conducting nutrition label education helps children improve their nutrition knowledge and leads to positive changes in dietary attitudes and eating behaviors. In particular, a direct nutrition education method is more effective than an indirect method such as a written message to parents. Therefore, it is suggested that systematic and constant 'nutrition label education' be performed by nutrition teachers in elementary schools to establish healthy eating habits based on choosing nutritious snacks and processed foods.

Objective: This study was to assess liver involvement in multiple myeloma with the aid of liver function tests. Materials and Methods: A hospital based retrospective study was undertaken using data retrieved of multiple myeloma from the register maintained in the Department of Biochemistry of the Manipal Teaching Hospital, Pokhara, Nepal between $1^{st}$ January, 2007 and $28^{th}$ February, 2012. We collected biomarkers of liver profiles including bilirubin (Total, Direct and Indirect), total protein, albumin, AG ratio, SGOT, SGPT, ALP, ${\gamma}GT$, LDH, ferritin, renal profile and hematological profile. Descriptive statistics and testing of hypothesis were used for the analysis using EPI INFO and SPSS 16 software. Results: Out of 37 cases of multiple myeloma, serum level of AST, ALT, ALP, ${\gamma}GT$ and LDH were increased above the cut-off point in 22 (59.5%), 24 (64.86%), 13 (35.13%), 9 (24.3%) and 11 (29.7%) respectively. The mean values of AST ($65.5{\pm}28.18$ U/L), ALT ($68.37{\pm}29.74$ U/L), ALP ($328.0{\pm}148.4$ U/L), ${\gamma}GT$ ($44.5{\pm}29.6$ U/L) and LDH ($361.7{\pm}116.5$ U/L), total protein ($9.79{\pm}1.03$ gm/dl) were significantly increased when compared with controls. In contrast, albumin ($3.68{\pm}0.43$ gm/dl) and the AG ratio ($0.62{\pm}0.15$) were significantly decreased. Similarly, anemia, hyperuricemia, azotemia, hypercalcaemia and Bence Jones proteinuria were found in 30 (78.9%), 27 (71.1%), 19 (51.5%), 15 (39.5%) and 16 (42.1%) respectively, in cases of multiple myeloma. Conclusions: While clinical manifestation of liver disease among the multiple myeloma was not common, abnormalities in liver function were characteristic.

We investigated whether divergent thinking attitudes mediate the relationship between self-esteem and creative teaching beliefs among teachers. We examined differences in the mediating model we proposed in the groups of pre-service and in-service child care teachers. We found differences in the pre-service and in-service child care teachers in the proposed mediating model. Especially in the pre-service child care teachers, the mediating effect of divergent thinking attitudes was confirmed. There was a significant effect from self esteem to creative teaching beliefs and also a significant effect from divergent thinking attitudes to creative teaching beliefs. But in-service child care teachers, there was neither direct nor indirect effect of self-esteem to creative teaching beliefs. Suggestions for more studies and for better in-service education for the pre-service and in-service child care teachers are recommended for the future.

The measurement and monitoring of the biochemical oxygen demand (BOD) play an important role in the planning and operation of wastewater treatment plants. The most basic method for determining biochemical oxygen demand is direct measurement. However, this method is both expensive and takes a long time. A five-day period is required to determine the biochemical oxygen demand. This study has been carried out in a wastewater treatment plant in Turkey (Hurma WWTP) in order to estimate the biochemical oxygen demand a shorter time and with a lower cost. Estimation was performed using artificial neural network (ANN) method. There are three different methods in the training of artificial neural networks, respectively, multi-layered (ML-ANN), teaching learning based algorithm (TLBO-ANN) and artificial bee colony algorithm (ABC-ANN). The input flow (Q), wastewater temperature (t), pH, chemical oxygen demand (COD), suspended sediment (SS), total phosphorus (tP), total nitrogen (tN), and electrical conductivity of wastewater (EC) are used as the input parameters to estimate the BOD. The root mean squared error (RMSE) and the mean absolute error (MAE) values were used in evaluating performance criteria for each model. As a result of the general evaluation, the ML-ANN method provided the best estimation results both training and test series with 0.8924 and 0.8442 determination coefficient, respectively.
