기후변화협약 대응을 위한 산림의 임목축적량과 변화량 탐지의 측면에서 국가산림자원조사는 신뢰성있는 산림통계량을 산출하기 위한 기반자료로서의 결정적인 역할을 담당하고 있다. 그러나 많은 정보들이 아직 행정구역단위 통계로만 산출되고 있어 산림 통계량의 공간적 분포와 같은 정보를 제공해주지는 못하고 있다. 따라서 본 연구는 국가산림자원조사 자료를 이용해 임상특성별 임분재적 추정모델을 개발하고, 임상도와 통합하여 임분재적의 공간분포를 추정하는 것을 목표로 하였다. 산림의 임분재적 추정모델 개발을 위해 연구대상지에 포함된 국가산림자원조사 자료를 이용하여 표본점별 임분재적과 흉고단면적합을 산출하고, 표본점의 임황정보(수종, 경급, 영급, 소밀도)를 모델개발에 활용했다. 결과적으로 수종, 영급, 소밀도 기준에 따른 임분재적 모델이 구축되었으며, 본 모델을 임상도에 적용해 임분재적 주제도와 불확실성 주제도를 제작했다. 임분재적 주제도에 의한 연구대상지의 평균 임분재적은 85.7 $m^3$/ha이며, 95% 신뢰구간을 고려했을 때 약 79.7~91.8 $m^3$/ha 구간에 포함되는 것으로 나타났다.

Korea has experienced dramatic development and has become highly industrialized and urbanized during the past 40 years, which has resulted in rapid economic growth. Due to the industrialization and urbanization, however, air pollutant emission sources have increased substantially. Rapid increases in emission sources have caused Korea to suffer from serious air pollution. An air pollutant emissions inventory is one set of essential data to help policymakers understand the current status of air pollution levels, to establish air pollution control policies and to analyze the impacts of implementation of policies, as well as for air quality studies. To accurately and realistically estimate administrative district level air pollutant emissions of Korea, we developed a Korean Emissions Inventory System named the Clean Air Policy Support System (CAPSS). In CAPSS, emissions sources are classified into four levels. Emission factors for each classification category are collected from various domestic and international research reports, and the CAPSS utilizes various national, regional and local level statistical data, compiled by approximately 150 Korean organizations. In this paper, we introduced for the first time, a Korean national emissions inventory system and release Korea's official 2007 air pollutant emissions for five regulated air pollutants.

The effects of nuclear data uncertainties are studied on a typical PWR fuel assembly model in the framework of the OECD Nuclear Energy Agency UAM (Uncertainty Analysis in Modeling) expert working group. The "Fast Total Monte Carlo" method is applied on a model for the Monte Carlo transport and burnup code SERPENT. Uncertainties on $k_{\infty}$, reaction rates, two-group cross sections, inventory and local pin power density during burnup are obtained, due to transport cross sections for the actinides and fission products, fission yields and thermal scattering data.

Purpose: This study was designed to explore the influencing factors on self-directed learning ability of nursing students and to investigate the relationship between learning style, learning attitude, and self-directed learning ability. Methods: The study sample was composed of 263 nursing students. Data were collected from March 8th to April 7th, 2011 using a questionnaire which included Kolb's learning style inventory, learning attitude inventory, and self-directed learning ability inventory. Results: Learning styles of the subjects were assimilator 33.8%, converger 31.9%, accommodator 24.7%, and diverger 9.5%. There was no significant difference in learning styles among grades. However, the total mean score of learning attitude (F=8.30, p<.001) and self-directed learning ability (F=2.85, p=.038) significantly differed among grades. Learning attitude positively correlated to self-directed learning ability (r=.62, p<.001). Learning attitude was the most significant predictor and accounted for 36.5% of the variance in self-directed leaning ability in nursing students. Conclusion: It is important for students to use all four learning styles rather than to rely solely on one style. There should be more emphasis placed on the development of positive learning attitude and self-directed learning ability of nursing students.

Objective: This study aimed to investigate the moderating effects of peer competence between children's perception of parenting attitudes and depression among $5^{th}$ grade elementary students. The differences are examined based by gender. Methods: 'The Children's Perception of the Parenting Attitudes Inventory', 'Children's Depression Inventory', and 'Peer Competence Inventory' were used to collect data from 200 elementary school students from Seoul, Korea. The research hypothesis were analyzed using t-tests, Pearson's correlation analysis, standard linear regression analysis and hierarchical multiple regression analysis via SPSS 21.0. Results: The results are as follows: First, only peer competence showed a difference between the boys and girls, where the boys scored higher than the girls. Second, there was a significant correlation between all the factors. Third, the moderating effect of peer competence on the father's parenting attitude was supported only in the boys. Conclusion: The results denote the need of a gendered approach to understanding problems and developing counseling programs to address depression among children. They also demonstrate that high peer competence can be used to treat depression in boys dissatisfied with their father' parenting attitude.

본 연구에서는 경인지역 도시가스회사들이 가스공사로부터 도매 매입한 도시가스의 양이 배관내재고 등의 기타 용도를 포함한 도시가스판매량과의 차이에 대해 검토하여 보고자 하였다. 1996년부터 2001년의 자료를 이용하여 가스공사로부터 매입한 물량, 배관길이, 판매자료, 손실, 자가소비, 기타의 항목으로 기존의 자료를 정리하였고, 이를 기초로 하여, 배관내 재고량 변화, 판매 자료에 기초한 추정 미검침 재고량과 그 이월분 등을 확인하였다. 또 이를 통해 우리의 관심의 대상이 되는 오차를 이해할 수 있는 틀을 제공하고, 사실관계의 확인을 실증적인 분석을 통해 제시하고자 하였다. 결과. 각 도시가스회사가 도매 매입한 물량이 미검침 재고량의 이월분, 배관내재고, 검침판매량, 손실, 자가소비, 기타를 합한 량보다 많다라는 통계적 가설을 기각함을 보인다.

Purpose: The purpose of the study was to investigate the relationships between the Myers-Briggs Type Indicator (MBTI) psychological type and marital satisfaction, divorce proneness, positive affect, and conflict regulation in couple visiting a clinic. Methods: Couples (n=62) who visited "M" couple clinic participated in the study. Data were collected from March to June 2009 using the Marital Satisfaction Scale, Marital Status Inventory, Positive Affect Inventory, and Conflict Regulation Inventory. Results: The couples showed no significant differences in marital satisfaction, positive affect, and conflict regulation according to similarities between spouses in MBTI types. However, they showed significant differences in divorce proneness of husband according to a similarity in the Sensing/Intuition indicator. They also showed significant differences in divorce proneness, positive affect, and conflict regulation between the couples for ISTJ (Introversion, Sensing, Thinking, Judging) or ESTJ (Extraversion, Sensing, Thinking, Judging) types compared to other couples. Conclusion: When nurses counsel couples, they should understand that differences in psychological type between spouses affects their marital relationship. In addition, nurses should educate couples on the characteristics of each type according to the couple's types and help them to understand each other, especially for couples where one spouse is the ISTJ/ESTJ type. These interventions will improve marital satisfaction and prevent the divorce in these couples.

The purposes of this study were to investigate the actual condition and to deal with the psychological characteristics of computer addicted adolescent using the Minnesota Multiphasic Personality Inventory (MMPI). The subjects of this study were 407(male 185, female 222) 2nd grade students in senior high school in Daegu. All participant were evaluated on the basis of the Minnesota Multiphasic Personality Inventory (MMPI) and the upgraded Computer Addiction Inventory (CAI) scale which referred to the Young's Internet Addiction Self Diagnosis Scale and the Mind Test's Came Addiction. SPSS version 10.0 was used for data analysis. The scores of F, Hs, D, Pd, Pa, Pt, Sc of the MMPI scales showed that there were statistically significant differences between computer addicted adolescents and non-addicted adolescents. The rate of addicted adolescents was significantly higher than that of non-addicted adolescent in psychological problematic score ranges in the scales. The characteristics of the scores of computer addiction adolescents were similar to those of alcohol and drug addicts in the scales of D, Pd, and Pt. This survey revealed that the psychological disorders suffered by computer addiction adolescents may cause more serious social problems than alcohol and drug addicts.
