The manufacturing industry is the backbone of the Korean economy. Among them, the petrochemical industry is a strategic growth industry, which makes a profit through reexports based on eminent technology in South Korea which imports all of its crude oil. South Korea imports whole amount of crude oil, which is the raw material for many manufacturing industries, by sea transportation. Therefore, it must respond swiftly to a highly volatile tanker freight market. This study aimed to make an early warning model of crude oil shipping market using a signal approach. The crisis of crude oil shipping market is defined by BDTI. The overall leading index is made of 38 factors from macro economy, financial data, and shipping market data. Only leading correlation factors were chosen to be used for the overall leading index. The overall leading index had the highest correlation coefficient factor of 0.499 two months ago. It showed a significant correlation coefficient five months ago. The QPS value was 0.13, which was found to have high accuracy for crisis prediction. Furthermore, unlike other previous time series forecasting model studies, this study quantitatively approached the time lag between economic crisis and the crisis of the tanker ship market, providing workers and policy makers in the shipping industry with an framework for strategies that could effectively deal with the crisis.

Recently, as the role of science and technology in social domain is more increased and the creative economy becomes a important matter in national development strategy, it is necessary that the improvement of legal system on science and technology for efficiently responding to paradigm shift into Innovation driven science and technology policy. Especially, The Framework Act On Science And Technology as a general and basic norm on science and technology policy is necessary to revise in systematic and substantial aspect in order to correspond with changed environment and current of the times. The Framework Act On Science And Technology was established in 2001 and revised several times, but substantial amendment reflecting the political facts as the need to demand was insufficient because it was revised only related with restructuring the government organization and changing the S&T Policy Coordinating Committee system. And therefore, this paper aims to review the problems and complementary factors and suggest the improvement draft on The Framework Act On Science And Technology. According to study, the revision methodologies are following : first, the Chapter and Paragraph of the law should be restructured to improve the systemicity, next the comprehensiveness, effectiveness, connections with related special laws and compatibility of the law should be complemented by adding the new provision or amending the inadequate provision to improve the position and function as a general and basic norm.

The purpose of this study was to examine dietary habits and nutrient intakes according to feeding method during infant period in elementary school students. Subjects were 1,251 elementary school students. Subjects were divided into three groups, breast-fed group (N=508), formula-fed group (N=397), and mixed group (N=346), according to feeding method during infant period. The questionnaire was composed of general characteristics, dietary conditions during infant period, dietary behaviors, and dietary intakes and was completed by children and children's parents. Average age, height, weight, and body mass index were 11.6 years, 139.0 cm, 34.6 kg, and $17.8kg/m^2$, respectively. The formula-fed group showed a smaller proportion of subjects with colostrum feeding (P<0.001) compared to the breast-fed and mixed groups. Frequency of eating snacks was significantly higher in the mixed group than in other groups (P<0.05). There was no significant difference in dietary habit total score and nutrient intakes according to feeding method during infant period. Feeding method in during infant period was associated with dietary habits (milk and vegetable intake habits) up to growth period of elementary school. A longitudinal and systematic study is needed to clarify this relationship.

The purpose of this study was to understand the laws related to the safety management of children's play facilities(LRSMCPF) including the "Safety Supervision Law of Children's Play Facilities(SSLCPF)" and the "Quality Management and Industrial Products Safety Management Law(QMIPSAL)", in order to analyze the problems by 4 phases-development of products, landscape design, landscape construction and maintenance considering landscape project procedure-and to propose a revision of the laws. The results are as follows: 1. The various LRSMCPF, SSLCPF and QMIPSAL, as basic laws for the safety management of children's play facilities, were insufficient regarding the features of children's play facilities and play spaces, which are both comparatively varied and complex. 2. In development of products, the one-year duration of safety certification based on QMIPSAL was too short and the procedure for safety certification were redundant in both products and plants inspection, and export and import product inspection. 3. The field inspection of construction sites based on SSLCPF was repeated with quality control and a consultation of rules based on "Construction Technology Management Law". 4. There are not enough safety inspection organizations regarding children's play facilities to meet the demand of safety certification, safety inspection, and safety education in the near future. 5. For children's play safety, the establishment of a general safety management system for children's play connected with the phases is needed to ensure safe play equipment, to construct safe playgrounds, and to manage play facilities. The criteria, regulations, and procedure regarding safety certification and safety inspection of play facilities must be revised efficiently and standardized to a global level as well. To improve the system and contents of safety certification and inspection, authorization of safety inspection organizations based on landscape architecture is needed. Further study will be required to concretely analyze in detail the laws, enforcement decrees and rules, and ordinances that consider the practical experience of professional landscape architects, inspectors, and lawyers.

'90년대에 들어서면서 급속한 경제성장과 함께 자동차수가 급증하여 '97년에는 1.000만대를 돌파 하였다. 자동차수의 증가와 함께 교통사고도 나날이 늘어 '96년에는 사망자가 12,600여명에 이르렀다. 교 통사고는 막대한 인명피해와 함께 사회적으로 많은 비용을 소모한다. 교통사고로 인한 사회적 비용의 추정은 교통안전사업의 효과분석 및 기타 교통관련사업에서 꼭 필요한 자료이다. 이제까지 국내에서 수 행된 교통사고비용은 1년간의 전체 사고비용만을 추정하고 사고등급별 사고건당 사고비용은 도출하지 못하였다. 이에 본연구는 교통관련사업에서 꼭필요한 자료이다. 이제까지 국내에서 수행된 교통사고 비 용은 1년간의 전체 사고비용만을 추정하고 사고등급별 사고건당 사고비용은 도출하지 못하였다. 이에 본 연구는 교통관련사업에 필수적인 사고심각도에 따른 교통사고비용을 도출하려한다. 교통사고비용을 산출하는 대표적인 방법에는 총생산손실법과 개인선호성법이 있으나 본연구에서는 총생산손실법을 이용 하였다. 교통사고비용 항목은 사고로 인한 생산손실비용, 의료비용, 차량수리비용, 행정비용 및 PGS(Pain, Grief & Suffering) 비용으로 구분된다. 이중에서 PGS비용은 국내에서는 처음으로 고려된 항 목으로 교통사고 피해자 및 가족의 물질적·정신적 피해비용을 의미한다. 본연구에서는 각 항목의 비용 추계를 가능한 한 종합적이고 체계적이며 구체적으로 산출하였으며 그결과 사고등급별 건당 교통사고비 용을 도출하였다. PGS를 고려하지 않은 경우 사망사고 1건당 2억4천만원이고 중상사고 1건당 2천3백만 원 경상사고 1건당 7백 9십만원으로 추정되었다. 또한 사망자와 부상자 1인당 평균사고비용은 각각 2억 1천만원과 1천1백만원으로 나타났다.

The structure of cerebrosides from soybean embryo was determined using fast atom bombardment mass spectrometer (FAB-MS), gas chromatography mass spectrometer (GC-MS) and TLC. The components of cerebroside were determined by GC-MS after acid hydrolysis. The molecular weight distribution of cerebroside was measured by positive mode FAB-MS with LiOH saturated 3-nitrobenzylalcohol(3-NBA) matrix. Structures of individual components of complex mixtures can be determined easily by this process. The major constituent of soybean extracted cerebroside was determined as the glucoside of N-2'-hydroxypalmitoyl-sphingadienine.

Most of the sample surveys conducted by several statistics preparation agencies are multipurpose surveys inquiring into several distinguishing items through a single sample. In a multipurpose sample design, the stratification tends to be very complex since the stratification variables which are both multivariate and heterogeneous must be considered collectively. In this paper we point out an outlier effect in a multivariate stratification to which the K-means clustering method is applied and propose to consider outliers prior to the stratification step. We also show an empirical stratification effect under consideration of outliers through a case study of sample design for The Rural Living Indicators.

산업통상자원부는 '17년부터 '31년까지 향후 15년간의 전력수급 전망 및 전력설비 계획 등을 담은 '제8차 전력수급기본계획'(안)을 마련하여 12월 14일 국회 산업통상자원중소벤처기업위원회(이하 산업위)의 통상 에너지 소위에 보고했다. 이번 계획(안)은 지난해 12월 계획 수립에 착수한 이래 약 1년간 70여명 전문가들의 43차례 회의를 거쳐 작성되었으며, 그간 수요 전망, 설비 계획, 예비율 등 5차례에 걸쳐 중간 결과를 공개하여 시민 환경단체, 에너지업계 등 이해 관계자로부터 의견을 수렴해 왔으며, 지난 9월에는 국회 산업위 통상에너지소위에 중간 보고를 하였다. 기존 수급계획이 수급 안정과 경제성 위주로 수립되었던 것에 반해, 이번 8차 계획은 최근 전기사업법 개정(전기사업법 제3조 개정('17.3월) : "전력수급기본계획 수립시, 전기설비의 경제성, 환경 및 국민안전에 미치는 영향 등을 종합적으로 고려하여야") 취지를 감안하여 환경성 안전성을 대폭 보강하여 수립한 것이 특징이다. 또한 발전소 건설을 우선 추진하기보다는 수요 관리를 통한 합리적 목표 수요 설정에 주안점을 두었고, 신규 발전설비는 대규모 원전 석탄 일변도에서 벗어나 친환경 분산형 재생에너지와 LNG 발전을 우선시하였다. 이번 수급계획은 국회 산업위 통상에너지소위 보고 외에도 국회 산업위 전체회의 보고, 공청회 등을 통해 추가적으로 의견을 수렴한 뒤 전력정책심의회 심의를 거쳐 최종 확정될 예정이다. 국회에 보고된 제8차 전력수급기본계획(안) 전문을 게재한다.

현대는 인터넷과 컴퓨터 없이는 잠시도 운용될 수 없는 사회이지만 이를 불법적으로 이용한 범죄행위도 점차 증가하고 있다. 이들 컴퓨터 범죄는 익명성에 기반한 대담성을 보이고 있으며, 개인의 사회적 존재로써의 자각에 있어서도 탈개인화됨에 따라 더 많은 우려를 낳고 있다. 이에 따라 일반 컴퓨터 사용자들의 프라이버시 보호를 위한 방법으로 암호화 방법을 점점 더 많이 사용하고 있는데, 이에 비례해 범죄자들의 암호사용도 증가하고 있다. 그렇다면, 범죄자들이 암호를 사용해 자신들의 범죄증거를 숨기고 있는 경우, 이를 수사하기 위해 공권력 및 수사기관은 어떻게 해야 될 것인가\ulcorner 본 논문은 이러한 문제제기를 통해 새로운 환경에 의해 변화된 코드를 활용하는 새로운 법제도를 통한 적극적인 대비방안을 모색해 보고자 한다. KLS와 같은 신기술을 수사기관 및 법집행기관이 신중하게 사용하여 국가의 법 집행력과 프라이버시권이라는 두 가지 근본 가치의 균형을 이룰 수 있는 방안을 고려하여야 할 것이다. PRIVACY와 SECURITY라는 동전의 양면은 현실생활의 법제도를 그대로 옮겨놓는 것만으로는 한계가 있다. 현재 암호와 관련한 보든 논의는 공론화 되지 못하고있다. 좀 더 공개적으로 암호를 사용한 범죄 행위에 대한 현황과 또 이를 대처한 수사기관의 수사 활동에 대해 논의하고, 그 과정에서 어떤 문제점들이 발생되고 있으며, 이들 문제를 해결하기 위해 필요한 조치들이 무엇인지에 대해 논의하고, 해외 각 국은 이 문제를 해결하기 위해 어떠한 노력들을 기울이고 있는지 살펴본후 종합적인 안목으로 시의 적절한 대책을 세우는 시발점이 되었으면 한다.
