The slag excavated from Gyesil-ri in Gongju, Yeonje-ri in Cheongwon and Beopcheonsaji (temple) site in Wonju are analyzed by X-ray Fluorescence Analyzer, metallurgical microscope, SEM-EDS etc., for chemical composition and microstructure to figure out the raw material and the iron manufacturing technique. First of all, as a result of principal component analysis, the total Fe-content of slag from Gyesil-ri is 39 to 44% and the modified rate is 15 to 21%, which is common in ancient iron slag. Yeonje-ri site is found the ancient iron-smelting furnace. The total Fe-content of slag from Yeonje-ri is 41 to 43% and modified rate is 18~30%, which is also the general value in the ancient slag. However only slag is excavated in the residential area at Beopcheonsaji site and there is no iron making relic. In addition, the result of principal component analysis contains that the total Fe-content of Beopcheonsaji site is 52 to 57%, and modified rate is 8 to 14%. It shows that the total Fe-content of Beopcheonsaji site is higher than relic from Gyesil-ri and Yeonje-ri and the modified rate is lower than other sites. This results mean that recollecting rate of Fe in Beopcheonsaji site is lower than other sites. Also, as a result of minor elements analysis, the slag from Gyesil-ri has the higher level of Ti, V and Zr than other sites and the microstructure are observed as magnetite and ulvospinel, so that the raw material of slag is iron sand. But the slag from Yeonje-ri and Beopcheonsaji site are identified to use iron ore. As a result of microstructure observation, fayalite, gray-columnar crystal, is found in the slag from Yeonje-ri and big wustite as main phase is observed in the slag from Beopcheonsaji site. This study show that the slag from Yeonje-ri is made of smelt ash produced during smelting works and the slag from Beopcheonsaji site is made of forging ash produced during forging work concerning the excavated location and the microstructure.

In this research, by examining the influence that high quality fine aggregate and low quality fine aggregate have on the strength of concrete through tests, the manifest strength of concrete according to high quality fine aggregate was reviewed. The results showed that compared to low quality fine aggregate usage mixture, the unit volume to achieve the same liquidity decreased and accordingly the W/B also decreased therefore increasing the strength of concrete, and as high quality fine aggregate was used, it is determined that there can be improvements to the economically feasibility of usage mixture and improvement in durability etc.

This research examines the constitutional meaning of the right to health through reviewing the decisions of the Constitutional Court and proposed amendment of the Constitution issued by the President. This article further discusses the relationship between the right to a humane livelihood and the right to health. Health is a fundamental freedom and inalienable human right which is a prerequisite to accomplish individual's independent activity and realization of value. Thus, the government is obligated to protect and uphold the right. Article 36(3) of the Constitution delineates the government's duty to protect and fulfill the right to health. Through the interpretation of both Article 36(3) and Article 34 of the Constitution, I suggest that the right to health implies 'the right to social security for health'. The Constitutional Court has narrowly interpreted the scope of the right to a humane livelihood by defining the term as "minimum material living standards". However, it should be interpreted as 'the right to enjoy a healthy and cultural life for human dignity' and setting the level of protection is solely on the discretion of the legislative branch. Ultimately, the judicial review on the right to a humane livelihood connects with the issue of rational control for legislative discretion.

The compressive strength of the soil stabilizer in the deep mixing method (DMM) depends on kinds of soil, particle size distribution, and water content. Because of this, Laboratory test has to perform to estimate the unit weight of binder to confirm the satisfaction of the design strength. In this study, uniaxial compression strength was measured by mixing the soil stabilizers developed in the previous study with clay in Busan, Yeosu, and Incheon area. And the strength enhancement effect was evaluated comparing with blast furnace slag cement (BFSC). Also, the relationship between the unit content of binder and uniaxial compressive strength was investigated in order to easily calculate the unit weight of binder required to ensure the stability of the ground at the field. As the results of the analysis, the relationship between the unit content of binder and the uniaxial compressive strength are ${\gamma}_B=(108.93+0.0284q_u){\pm}35$ when W/B is 70%, and ${\gamma}_B=(122.93+0.0270q_u){\pm}40$ when W/B is 80%.

독일의 응급구조업무의 조직은 독일 기본법(GG) 제30조, 제70조에 따라 오로지 연방부들에게 있다. 유럽 연합은 기술적 조직적 통일성과는 별도로 각각의 국민들의 건강보호의 일부분으로 응급구조의 조직과 재정에서 상당히 광범위하게 재량을 인정하고 있으며 이에 따라 유럽연합의 시스템과 정책들의 입법적 조화를 사실상 포기하고 있는 실정이다. 독일연방주들은 자신들의 주응급구조법률(LRDG)에서 응급구조업무의 보장을 일반적으로 재차 지방자치단체(주 근교도시중심)에게 독자적인 업무로서 인정하고 있다(가령 슐레비히 홀스타인주 응급구조법(RDGSH) 제6조). 이러한 주들은 응급구조를 자신의 관할지역에 대해 준비하고 스스로 운영하거나 운영통제할 수 있는 구조목적의 단체들(RZV)과 공동협력을 할 수 있다. 각각의 업무능력과 법적인 기준에 따라 구조 목적의 단체들(RZV)은 자신의 이름으로 응급구조를 운영하거나 하나 또는 다수의 기관(공공 구조서비스 혹은 사설 구조서비스)에게 시행을 위임할 수 있다. 이러한 측면에서 본 연구에서는 독일의 경우 의사가 직접 현장 의료를 담당하고 있다는 점에서최근 입법을 통해 응급구조사의 교육과정을 개편하고 있으며, 질적 향상을 통해 응급의사와 응급구조사의 권한범위에서 독일 응급구조사의 권한확대가 시도되고 있다는 시사점을 도출하고 있다.

In the case of concrete recently manufactured with a concrete mixing truck, although aggregate and cement are used as the main ingredients, from a costs savings perspective, low quality aggregates are processed and used as concrete aggregate. In the case of these low quality aggregates, the unit volume and unit binder weights are increased for manufacturing, and due to this problems such as dry shrinking of the architecture and economic infeasibility have arisen. Therefore by changing the aggregate material and the unit binder weights that are currently being distributed, this research analyzes the influence on concrete.

International arbitration is the important field of applying CISG and the backbone of uniform law developed by CISG. Now CIETAC tribunals like courts of contracting states apply CISG precisely, which is beneficial to improving the quality and the credit of arbitral cases. Arbitration has the characters of independence and the non-government. the legal foundation of arbitral tribunal's applying CISG are the national arbitral law, the applicable arbitral procedures and usages of arbitration, not for performing international obligations under the CISG. CIETAC mainly use China Contract Law and CISG over the cases of sale of goods. Because of no provisions on recovery of differential price loss (equal to article 75 and 76 of CISG) Chinese tribunals have more discretion in determining the sum of damages under the China Contract Law. Applying China Contract Law may not beneficial to aggrieved party.

The DMM (Deep mixing method) is a construction method in which an improved pile is installed in the soft ground by excavation ground using an auger and then mixing ground stabilizer with soil. Improved pile installed in the soft ground by the DMM may have different compressive strength depending on the properties and characteristics of the soil. In the previous study, laboratory tests were performed on the ground stabilizer for the DMM developed by using the ash of the circulating fluidized bed boiler as a stimulator for alkali activation of the blast furnace slag. And the test results were analyzed to derive the correlation between the unit weight of binder (γ_B) and the uniaxial compressive strength (q_u). In this study, comparative reviews were conducted on the correlations derived from the same laboratory tests on soil material collected from the Saemangeum area and the stability of the site was evaluated by analyzing the test results performed at the site. As a result, the clay collected from the Saemangeum area satisfies the correlation between the unit weight of binder (γ_B) and the uniaxial compressive strength (q_u) derived from the previous study. And the result of the test at the field showed a higher uniaxial compressive strength than the standard strength at the field, indicating excellent stability.
