To achieve the aim of science education, it is known that warious teaching, and learning materials should have to be used. As a sub-textbook for primary science education, 'Sil Hum-Kwan Chal (Experiment and Observation), teaching and learing material are developed and using now in science. This material have following characteristics; (a) Soruce-book contains reading materials for additional information, various pictures to enririch the science concepts, and supplementary and enrichment activities. (b) Work-book consists of the detailed procedures of activities of experiments presented in the textbook, student can record the experimental procedures and results. (c) Operational manuals provide operation techniques for experimental equipments which are used in science class. In this study the using status are surveyed for the 3rd grade of primary school, and based on this survey the improvement plan are discussed in view of design, quantity and utility, of sub-textbook.

This paper presents the survey results of the interruption on domestic customer, especially commercial, with primary focus on the cost are presented. General method utilized in quantifying the benefit of reliability on power system is to estimate the Customer Interruption Cost(CIC) associated with the electric service interruption. According to change the circumstance of electricity market by the deregulation and the introduction of new technology, reliable and accurate CIC is required for estimate the applied plan and technology under the circumstance. This paper presents the commercial customer interruption cost is estimated by the survey conducted by KEPCO in 2009. To collect the customer interruption data for calculation of CIC, the survey is conducted.

The study is a Post-Occupancy-Evaluation on newly constructed steel framed school buildings sponsored by POSCO, and presents alternative tactics for planning and programming for the kind of project. The schools in concern are Seowha Primary School(Incheon city) and Galma Primary School(Daejeon city) which were completed in February 1999 and since occupied. The POE-2000 study results had to be compared to the POE-1999 which dealt on Jigog Primary School(Pohang city) and Iwol Primary School(Jincheon township) to develop an improved project tactics. In this reason we had to use the same questionnaire forms envisaged by the former study, ie. POE-1999. To begin with the same study format, it might be appropriate to differentiate whether a 'satisfaction' comes from the 'steel framed construction' or from the 'newly built environment'. However it was difficult with the POE-1999. As the intention to compare the 4 school building were the firstly achieved objective of this study that we had to continue to apply the same format and the analysis procedure. Except this condition, everything the POE-1999 conducted were valuable to this POE-2000. The satisfaction survey form includes 36 questions for individual items and 2 questions for general items.

This study was aimed to find out ancestral environmental protection wisdom in their life style, and to teach environmental education applying its results in primary school. A dissertation survey was conducted to analyze environmental protection eco-wisdom, environmental education about traditional culture, application of indigenous knowledge in ancestral traditional culture for environmental education in the primary school, and Korean traditional culture presented in 5th grade subject courses of the 7th school curricula. In addition, a environmental education program was developed by applying wisdom of traditional life style and the strategy of environmental education utilizing the results from the above data in primary school was explored. It was found that students understand the value of environment education and are more interested in the ancestral life style, environmental protection wisdom from traditional culture. Also, students understand the ancestral thinking in environment, the wisdom of old Korean, and the importance of echo-wisdom related on traditional culture. Based on above results, the suggestions of this study are made as follows. First, by searching for more wisdom from traditional culture vigorously, it is needed that developing more teaching text combined environmental education with traditional culture through other curriculums. In addition, for this kind of teaching being used efficiently in another schools, the place and environmental teaching aid is needed.

This study investigates the management performance of primary medical centers on the basis of power process perspective to suggest the direction for their competitive advantages. To do so, this study conducts the questionnaire survey to middle and top managers of primary medical centers in Seoul, Incheon, and Kyoungki Province and analyzes the data by using cluster analysis and variance analysis of SPSS statistical package. According to the results, the types of primary medical centers are determined by the interaction of power determinants variables, and the type of primary medical centers which has the strongest interaction of power determinants variables shows the highest management performance compared to other types.

This paper describes an overview of the packaging industry in Korea. Packaging plays an important role to connect the dot between primary and secondary industry. Moreover, it performs the visual merchandising of product, resulting in synergetic effect with quality of merchandise. As more convergence of primary and secondary industry accelerates, packaging industry became more competitive as well as critical area. Korea Packaging Center (KOPACK) in Korea Institute of Industrial Technology (KITECH) has conducted the national market survey of packaging industry since 2010, biannually. Firstly, Korea packaging industry was categorized. For defining the Korea packaging industry, Korea Standard Industry Code (KSIC) is used to divide the group into wood, paper, plastic, glass, metal and packaging machinery. Based on these categories, the market size was estimated with survey of 2,180 packaging companies. In this study, the results of this survey are summarized, and the key trends of each category are described.

In the theory of retrial queues it is usually assumed that the flow of primary customers is Poisson. This means that the number of independent sources, or potential customers, is infinite and each of them generates primary arrivals very seldom. We consider now retrial queueing systems with a homogeneous population, that is, we assume that a finite number K of identical sources generates the so called quasi-random input. We present a survey of the main results and mathematical tools for finite source retrial queues, concentrating on M/G/1//K and M/M/c//K systems with repeated attempts.

Purpose: Lactose intolerance (LI) is perceived to be frequent in Asia and has been reported to have considerable impact on dietary intake, nutritional status and the quality of life. We aimed to gather information from healthcare professionals on the perceived incidence, diagnosis and management of LI in 1 to 5 year old children in Southeast Asia. Methods: An anonymous electronic survey was sent randomly among healthcare professionals registered in the database of the pediatric societies in Thailand, Indonesia, and Singapore between June and October 2016. Results: In total, 259 health care professionals responded of which 45.5% (n=118) were from Thailand, 37.4% (n=97) from Indonesia and 16.9% (n=44) from Singapore. Of the participants who responded (n=248), primary LI prevalence among children 1 to 3 years of age was estimated to be less than 5% by 56.8%. However, about 18.9% (n=47) answered they did not know/unsure. Regarding secondary LI, 61.6% of respondents (n=153) estimated the prevalence to be less than 15%. But again, 10.8% (n=27) answered they did not know or unsure. Rotavirus gastroenteritis was ranked as the top cause for secondary LI. There was considerable heterogeneity in the diagnostic methods used. The majority of respondents (75%) recommended lactose-free milk to manage primary and secondary LI. Conclusion: More education/training of pediatricians on this topic and further epidemiological studies using a more systematic approach are required.
