The purpose of this study is to present a scheme to encode all possible lexical entities in dictionaries, glossaries, encyclopedias, and thesaurus, etc. First, it discussed the nature and structure of dictionaries. Second, two current major terminological data encoding schemes, MARTIF and TEI were analyzed in terms of their flexibility for extension to encompass all lexical entities. Third, an integrated microstructure of dictionaries was presented and compared with the MARTIF and TEI for print dictionaries. Then, the need and 17 suggestions for extended MARTIF and TEI formats were addressed with specific cases, which combined with the suggestions from two studies concerning MARTIF and TEI DTD modification for the markup of Korean dictionary entries.

The purpose of this study is to analyze the factors affecting the quality of life of elderly people from the ecological perspective. Specifically, this study attempts to compare the relative contributions of the variables from the individual system, microsystem, mesosystem, and macrosystem on the quality of life of the elderly people. The subjects for this study consisted of 443 elderly over 60 years old in Daegu city, Gyeongsang-do, and Chungchung-do areas. The data were collected randomly by interviews with a structured questionnaire, and analyzed by frequencies, means, ANOVA, and hierarchial regression method. The major-findings of this study were as follows: 1. The quality of life of the elderly consisted of four factors; physical, economic, psychological, and social factors. The highest satisfaction score for the quality of life was found in psychological factors, The global satisfaction score for the quality of life was found to be relatively high. 2. Out of the individual factors influencing the quality of life of the elderly, the economic status of the respondent was found to be the most important. Out of the microsystemic factors, the most important factors were found to be the intimacy with the spouse and with the children. Out of the mesosysystemic factors, the degree of the social participation of the elderly was found to be the most significant. However, none of the macrosystemic factors were found to be important in influencing the quality of life of the elderly people. 3. The relative significances of the variables contributing to the quality of life of the elderly were analyzed using a hierarchical regression technique. It was found that there was no significant factor in social background and mesosystemic variables. On the other hand, the degree of the self-efficacy and the level of the economic status from the individual factors, and the intimacy with the spouse and the children from microsystemic factors were found to be very significant in contributing the quality of life of the elderly.

There are lots of variations on speed, acceleration and engine power during vehicle driving. It is well known that Green House Gas emissions by these dynamic driving properties are not precisely estimated by the average speed based emission estimation model which has been currently used in Korea. MOVES are selected as an appropriate transferable model among Micro-level emission estimation models. Based on MOVES, a novel emission estimation model can be used in Korea is developed. In this model, MOVES concept of emission estimation method and the MOVES method of estimating the Micro-level emission rate map is adopted. The results from the proposed model were compared with those from the average speed based emission model. The comparison results show the estimated base emission maps are good to be applied in Korea, but needed to be adjusted to consider the vehicle size differences between the two countries. Therefore, the factors for calibrating vehicle size difference were calculated and applied to acquired the micro-level emission maps for the Korean standard vehicle types.

한국의 농촌위기를 농업생산과 농민생활의 기초적 조직단위의 차원에서 살펴보면 문제의 핵심이 가족농의 재생산체계의 와해에 있음이 드러난다. 농촌가구의 재생산주기 단계별 분포를 볼 때, 이른바 축소기 및 해체기에 있는 가구의 비율이 급속히 증가하고 형성기 및 확대기에 있는 가구의 비율은 급속히 감소함에 따라 한국의 가족농체제는 그 미시조직적 기반이 와해되어 가고 있음이 드러난다. 아울러 가족 재생산 주기의 각 단계인 양육 및 교육, 농가경제 계승과 혼인, 노후 부양 등의 과정에서 동시적으로 나타나고 있는 혼돈과 단절이 농촌의 기초조직인 농가의 존속 자체를 어렵게 만듦으로써 정상적 농가 없는 농촌의 총체적 퇴행이 나타나고 있다. 종합적으로 말해 가족농 재생산체계가 그 양적인 측면과 질적인 측면 모두에서 심각한 위기상황에 처해 있는 것이다. 본 연구의 결과에 기초해 볼 때, 한국 농촌의 현실은 기초 생산,생활조직의 차원에서 급격한 해체는 진행되고 있으나 적절한 재구조화(restructuring)는 이루어지고 있지 못한 상황이다. 따라서 생산조직 차원에서의 농촌문제의 대처는 기존 농가 재생산 주기의 붕괴에 관한 다양하고 즉각적인 대증요법을 동원해 가족농 해체의 부작용을 최소화시키는 한편, 보완적 조치로서 새로운 협업적 또는 기업적 경영체계의 확립에 관계된 사회적 필요조건들을 충족시키는 것이어야 할 것이다.

The Purpose of this study was to investigate the ecological variables on adolescent's sociometric popularity. Independent variables were organism(sex, age, aggression, self-esteem, impulsiveness, prosocial behavior, dominance), microsystem(parenting style, family support, friends relationship, teacher support), mesosystem(family-peer relationship, family-school relationship), and exosystem(positive community environment, social support of extended family, school's policy). The subjects were 835 - 1st and 2nd graders of two middle and two high schools in Daegu. Adolescent's sociometric popularity and ecological variables were measured with questionnaire. Adolescent's sociometric popularity was measured with sociometric popularity questionnaire. Organism variables were measured with sex, age, aggression, self-esteem, impulsiveness, prosocial behavior and dominance questionnaire. Microsystem variables were measured with parenting style, family support, friends relationship and teacher support questionnaire. Mesosystem variables were measured with family-peer relationship and family-school relationship questionnaire. Exosystem variables were measured with positive community environment, social support of extended family and school's policy questionnaire. The data analyzed by frequency, percentage, mean, cronbach's $\alpha$, and multiple regression. The major findings were as follows: First, adolescent's sociometric popularity was affected by age, overt aggression, academic self-esteem, social self-esteem, and impulsiveness of organism variables. Second, adolescent's sociometric popularity was affected by mother's affectional parenting, mother's control parenting, and attachment to friends of microsystem variables. Third, adolescent's sociometric popularity was affected by family - peer relationship and family - school relationship of mesosystem variables. Fourth, adolescent's sociometric popularity was affected by appraisal support of extended family, after-school activity, and circle activity of exosystem variables.
