  • This study developed a settlement environment diagnostic indices (SEDI) of rural villages which can apply to analyze variable conditions of villages having development projects. The index consists of 5 diagnostic areas (first level) with 13 items (second level), including detail indices of 40 criteria (third level) defined by specialists' brainstorming process. In order to develop the index system, object-oriented approach was used to extract the 5 diagnostic areas (infra-basic settlement facility, life condition & environmental resources, industry & economic infrastructure, community, and residents) from rural villages. For the 40 criteria, it was introduced a quantification method that all villages have absolute values in national level, not relative value between villages within an unit area. The diagnostic diagram and table were developed to evaluate the villages compositively. The developed SEDI was applied to study areas, 56 villages in 2 subdivision areas of county, located on county of Keumsan. Applicability of the index system, database system should be developed with the surveying method of data in village level.

  • To point out the Confucian Influence in Chosun, we deal with religious ceremonies, the decline of drinking tea, the spread of dog meat and the development of nutrition for the aged. The result is follows. First, the chosun confucianism changed the Buddhist familty ceremonies of Koryeo period into the confucian cermonies formed by Chu-Tzu's influence. So, buddhist sacrificial table turned into confucian one which was more systematric and more formal on the basis of chosun culture of food. Second, Chosun confucian scholars shrank from drinking tea because tea was the symbol of Buddhism. As a result, our people came to drink " Sung-nyung(scorched-rce tea)" and the common people drank Maggeolli instead of syung-nyung. Furthermore, this resulted in developing some kind of beverages. third, the people of Chosun had little rejection to dog meat and it was popularized in Chosun, Dog maet was popular in Chinese countries, Chu. Chin. and early Han. Later, dong meat almost disappeared except the purpose if healing. the reason why people had little rejection to dong meat in Chosun was that Chosun Conflucianism was the revival of Chu. Fourth, Chosun's state religion was confucianism which emphasize filial duty, the basis of humanity. The gentry researched into medication and nursing I case their old parents got sick. As a result, nutrition for the aged was developed.

  • In most machining companies, operators decide the cutting condition, a pair of spindle speed (5) and table federate (F) by experience and subjective judgment. As cutting conditions are determined by operators' experience and ability, inconsistent cutting conditions are given in same operating conditions. The objective of this study is to develop the cutting condition decision system which utilizes shop data and predicts tool life by neural network and eventually leads to the optimal cutting condition. The production time per piece is considered for an optimization object. We will discuss the process of an optimal cutting condition decision by neural network. By this process, a series of shop data is stored. And neural network is constructed for prediction of tool life and the optimal cutting condition is recommended from a cutting condition decision system using the stored shop data. The results show that the developed system is rational in searching the optimal cutting conditions on job operations.

  • ISO 10303-AP241 is an Application Protocol of ISO 10303, which specifies the representation of AEC facility's life cycle information. The Working Draft of AP241 was submitted to the TC184/SC4 of ISO in July, 2007 by Korean team of ISO TC184/SC4/WG3. This paper introduces the currently developed draft Ap241 core model, and describes the life cycle support modules which are required to represent the life cycle information of AEC facilities. The draft core model is developed as a generic data model which is useful as a basis for implementation in a data warehouse. This core model could be used in combination with reference data such as PLCS RDL, Gellish table and RDL of ISO 15926. These concepts already exists in ISO 10303-AP221, AP239 and ISO 15926. In order to support maintenance and feedback of operational information concerning the AEC facilities, the AP241 team re-used many modules from AP239, and developed various STEP Application Modules which are adapted from the ISO 15926.

  • This study was conducted to analyze the nutrition education and diet contents presented in toddler picture books. The study was conducted from August to October 2015 and examined five of Korea's major online bookstores. Finally, we analyzed 296 books, and 67 books contained dietary life contents. The contents of nutrition education were mainly about eating an even diet and keeping good table manners. However, contents of specific, practical dietary guidelines were not included. Therefore, it is recommended to eat a variety of vegetable side dishes at every meal, eat on time and not eat salty, sweet and fatty foods. Most parenting styles on feeding practice for nutrition education were dictatorial. To make parenting styles more effective, the parents' style should be more desirable. In order to provide internal motivation for toddlers and have a positive education effect, teaching methods on eating using picture books should be presented in a positive way. Food often appearing in picture books were vegetables, but green leafy vegetables were hardly observed. Foods that frequently showed up in picture books were pastries, which reflect Westernized food culture.

  • The energy density, power density and ohm resistance of battery change significantly as results of battery aging, which lead to decrease in the accuracy of the equivalent model. A parameter identification method of the equivale6nt circuit model with 3 R-C branches based on the test database of battery life cycle is proposed in this paper. This database is built on the basis of experiments such as updating of available capacity, charging and discharging tests at different rates and relaxation characteristics tests. It can realize regular update and calibration of key parameters like SOH, so as to ensure the reliability of parameters identified. Taking SOH, SOC and T as independent variables, lookup table method is adopted to set initial value for the parameter matrix. Meanwhile, in order to ensure the validity of the model, the least square method based on variable forgetting factor is adopted for optimizing to complete the identification of equivalent model parameters. By comparing the simulation data with measured data for charging and discharging experiments of Li-ion battery, the effectiveness of the full life cycle database and the model are verified.

  • The purpose of this study is to examine how the floor heating system is affecting to users in childeren's libraries. This study included the method that extracts the affordance of the floor heating system, after surveyed using behavior in children's libraries and referred to J. J. Gibson's affordance and surface concepts. As the positive affordance, it was grasped that the floor heating system promotes social relationships and affords various surfaces for library using, but also as the negative affordance, that hinders users in the public usings and the behaviors for reference and using. The behaviors of these various characters can be regarded as life behaviors resulted from the sitting life style and the natural using behavior can give to children emotional rest and autonomous reading experience. For the function as the children's library, the learning of sociality in the public building and the various reading space, the space planning of children's library should be done after the positive and negative affordances extracted from this study are reflected. The guidelines for space planning are summarized as the followings: the layout of book furniture, the shoe chest and the space around that, the furniture hight and children's eye level, and the practical using of the table for sitting life style.
