The seasonal variability of the sea surface winds over the last Sea of Korea (Japan Sea) is investigated by means of empirical orthogonal function (EOF) analysis. The combined representation of fields of three climatic variables by empirical orthogonal functions is discussed. The eigenvectors are derived from daily sea level pressure, wind speed and 10-day mean sea surface temperature (SST) during 15 years $(1978\~1992)$. The spatial patterns of the mean pressure are characterized by the high pressure in the western part and the low pressure in the eastern part. The spatial distribution of the standard deviation (SD) of pressure are characterized by max SD of 6.6 mb near the Vladivostok, and minima along the coast of the Japan. In Vladivostok, the maxima of SD of SST and south-north wind (WV) were also occurred. The representation of fields of individual meteorological variables by EOF shows that the first mode of the west-east wind (WU) explain over $47.3\%$ of the variance and the second mode of WU represents $30\%$. Especially, the first mode of the WV explain $70.9\%$ of the variance and their time series coefficients show 1-cpy, 0.5-cpy frequency spectrum. The spatial distribution of the first mode eigenvectors of SST are characterized by maximum near Vladivostok. The combined representation of fields of several variables (pressure, wind, SST) reveals that the first mode magnitudes of the variance of the combined eigenvectors (WU-PR) are increased. By means of this result, the 1-year peak and the 6-months peak are remarkable. In the three combined patterns (wind, pressure, SST), the second mode of the eigenvector (wind) is affected by the SST. Their time coefficients of the first mode show noticeable 1-year peak. The spectral analysis of the second mode shows broad seasonal signal with the period of 4-months and a significant peak of variability at 3-month period.

The purpose of this study was to compare and analyze the science process skills and teaching methods between the 6th and the 7th elementary school science textbooks. For this study, science textbooks and teacher's guidebooks from the 3rd to the 6th grade were analyzed. In this research the science process skills are divided by basic process skills(BPS) and integrated process skills(IPS). The BPS is composed of observing, classifying, measuring, predicting and inferring skill, which are 5 subcategories. The IPS is composed of problem cognition, formulating hypothesis, controlling variables, transforming data, interpreting data, drawing result, and generalization, which are 7 subcategories. The results found in the analysis of science process skills in the 6th and 7th science textbooks are as follows: 1. The percentage of the BPS was increased, but the IPS was decreased in the 7th than the 6th. 2. The percentage of the IPS was higher than the BPS in the 6th science textbooks, but the BPS was higher than IPS in lower grade and the IPS was higher than the BPS in higher grade in the 7th textbooks. 3. Observing and problem cognition skill were most dominant in the 6th and 7th science textbooks. 4. The percentages of observing(24.8%), classifying(5.4%), measuring(5.6%), inferring(6.0%) in the BPS and interpreting data(4.4%) in the IPS were increased, but predicting(3.8%), formulating hypothesis(0.5%), controlling variables( 1.8%), transforming data( 1.2%), drawing result(0.8%) and generalization(0.9%) skills were decreased in the 7th. And teaching methods suggested in the curriculum are as follows: the percentages of learning by observation(19.2%) and role play(0.1 %) were decreased, but learning by experiment(6.2%), learning by discussion(2.0%), learning by investigation(4.6%) and creative learning(6,4%) were increased in the 7th than the 6th. In conclusion, it was found that the basic process skills were emphasized in the 7th science textbooks than the 6th and the science process skills in the science textbooks of the 7th curriculum were distributed by the grade level of the elementary children.

After industrialization, the labor force participation rates of women, especially married women is drastically increasing. So, this study was designed to analyze the determinants of married women's employment status considered. For this, the determinants of married women's employment status were divided into individual-related, children-related, household-related and job-related variables to establish the research models. Based on this, the following results were drawn from a multinominal logistic regression analysis of the determinants of married women's employment status. First, an analysis of individual-related variable showed that married women had the employment status of labor wages with residence in the center of the city and high academic background. Second, an analysis of children-related variable showed that they had the employment status of labor wages with many their children and no their children under the age of six. Third, an analysis of household-related variable showed that they had the self-employment status of labor wages with nuclear family and few income earners of family members. Finally, an analysis of job-related variable showed that they had the employment status of labor wages when they got a job before they got married, their husband didn't get a job, and their husband worked in a professional field. As for findings stated above, as there was a difference in the determinants of married women's employment status, the ways for improvement in the married women's employment status would be suggested as follows. First, married women with young children have the low employment status, basically, requiring problem-solving ways for this because the housekeeping and child-rearing burden caused by marriage and childbirth are factors that continue to obstruct a job. For this, the flexible working hours system, which housekeeping and child-rearing can harmonize with economic activities like developed countries, needs to be activated. But the activation of such flexible working system will produce actual results under institutional protection, such as a related-protection law. Second, the Leave of Child Care System is debated as one of the most representatively systems that housekeeping can harmonize with economic activities. Now, although the System is legislated, the use is very poor.

Since 'Private Investment Act for Social Infrastructure Facilities' were changed in January 2005, BTL projects have been activated in the market. Nevertheless, several problems have been indicated as to the BTL system. Most of these problems are about the choice and scale of the target facilities and the reasonable rate of return allowed to the private investors, which are directly related to the VFM (Value for Money) analysis for the BTL projects. This study discusses the concepts and the methodologies of the VFM analysis, reminds its importance by investigating current problems of the BTL system concerned with the analysis, and suggests useful implications and alternatives through the case studies on the four ongoing BTL projects for the educational facilities.

에코톱은 생태학적 지휘체계(Niche)와 서식처(Habitat)가 결합된 환경을 의미하며 도면에서 최소한의 단위로 일반적인 구성요소의 상태, 잠재자연식생, 잠재생태계 기능으로 균일하게 분류가 가능한 요소로서 천이단계 또는 토지이용이 서로 다른 패치들로 이루진 생태공간을 의미한다. 따라서 에코톱과 비오톱은 식물과 동물의 특정 군집에 요구되는 서식공간의 개념에서는 의미가 같지만 비오톱은 서식공간의 일부분 또는 한 개 이상의 생물이 서식가능한 공간의 개념으로 사용된다. 현재 네덜란드, 스페인을 포함한 유럽국가에서는 에코톱분류를 통한 하천을 관리하는 방안을 제시하고 있으며 이에 대한 많은 연구가 진행되고 있다. 본 연구에서는 만경강 중류 소양천 합류점에서 전주천 합류점까지 약 3.5km 구간의 제외지포함 제내지 1km 폭을 대상으로 1918년 고지도 토지피복을 분류하고, 1948년 해방이전 항공사진, 2003년 2014년 항공사진을 활용한 에코톱을 분류하여 이에 대한 에코톱 다양성지수를 추이분석하여 하천으로부터 떨어진 거리 별 에코톱다양성지수 변화를 분석하였다. 분석결과 과거 제방축조 이전인 1918년 에코톱 다양성 지수는 하천으로부터 멀어질수록 안정적으로 감소하였으나 1948년 이후의 하천은 제내지에서부터 지수값이 급격히 감소한 것을 알 수 있었다. 이는 1948년 이후의 만경강은 과거 1918년 하천에 비해 구하도 공간이 농경지 증가, 보설치 등으로 인한 인위적 교란에 의한 감소로 분석되어지며 에코톱다양성과 밀접한 연관이 있는 생물종다양성 역시 감소하였음을 유추할 수 있다.

This paper analyzes the source code of FIPS-OpenSSL cryptographic module approved as FIPS cryptographic module in USA and shows how the selftest requirements are implemented as software cryptographic library with respect to pre-operational test and conditional tests. Even though FIPS-OpenSSL follows FIPS 140-2 standard, lots of security requirements are similar between FIPS 140-2 and Korean cryptographic module validation standards. Therefore, analysis from this paper contributes to help Korean cryptographic module vendors develop correct and secure selftest functions on their own cryptographic modules, which results in reducing the test period.
