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.

본 논문에서는 로봇팔의 선단을 잡고 원하는 위치로 이동시켜서 작업을 직접 교시하는 직감적인 교시 및 제어를 시스템을 개발하였다. 개발된 시스템은 로봇팔 선단부의 위치 방향 및 자세 방향 힘을 측정하는 6축힘 센서, 선단부에서 측정된 힘에 의한 로봇팔 관절 속도제어 명령어 생성 알고리즘, 자체 제작한 6축 로봇팔 및 제어 시스템으로 구성된다. 선단부 핸들러에 부착된 힘센서를 통해 로봇팔 조작자가 핸들러를 조종하는 위치 자세의 6차원의 힘/토크를 감지하고 이를 선단부 조종속도 명령으로 변환하여 6축 로봇팔을 제어한다. 연구 방법의 검증은 자체 제작된 6축 로봇으로 실행하였으며, 조종자의 핸들러 조정을 통한 작업교시에 의한 실험을 통해 제안한 힘 센서기반 로봇 선단 제어 방법이 성공적으로 동작함을 확인하였다.

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.

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.

본 연구에서는 자아존중감과 창의적 교수신념의 관계에서 확산적 사고에 대한 태도의 매개효과가 예비 유아교사와 현직 유아교사에 따라 다른 양상을 보이는지 살펴보고자 한다. 연구대상은 인천광역시와 경기도에 현직 유아교사 157명, 예비 유아교사는 244명으로 자아존중감, 확산적 사고에 대한 태도, 창의적 교수신념에 대해 설문조사를 하였다. 자료분석은 두 집단을 대상으로 구조방정식을 이용하여 확산적 사고에 대한 태도 매개모형을 각각 독립적으로 검증하였고, 두 집단 연구모형의 적합도와 변인 간 회귀계수를 산출하였다. 각 모형의 적합도를 평가하기 위해 적합도지수를 이용하였고, 매개효과를 검증하기 위해 Z검증을 실시하였다. 분석결과 예비-현직 유아교사의 경우 모두 자아존중감이 확산적 사고에 대한 태도에 정적으로 유의미한 영향을 주는 것으로 나타났으나 자아존중감이 창의적 교수신념에 직접적으로 미치는 영향은 유의하지 않는 것으로 나타났다. 구체적으로 현직교사의 경우 확산적 사고에 대한 태도가 창의적 교수신념에 유의한 영향을 미치지 않으며 자아존중감이 창의적 교수신념에 미치는 직, 간접 효과 모두 나타나지 않았다. 반면, 예비 교사의 경우 자아존중감이 창의적 교수신념에 미치는 직접효과는 없었지만, 확산적 사고 태도를 통해 창의적 교수신념을 설명하는 간접효과는 유의한 것으로 나타났다.

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.
