Single analytical procedure including extraction, liquid chromatography, and mass spectrometric analysis was evaluated for the simultaneous measurement of lysophospholipids (LPLs). LPLs, particularly, lysophosphatidic acids (LPA) and sphingosine 1-phosphate (S1P) are lipid messengers ubiquitously found in various biological matrix. The molecular species mediate important physiological roles in association with many diseases (e.g. cancer, inflammation, and neurodegenerative disease), which emphasize the significance of the simple and reliable analytical method for biomarker discovery and molecular mechanistic understanding. Thus, we developed analytical method mainly focusing on, but not limited by those lipid species S1P and LPA using reverse phase liquid chromatography-tandem mass spectrometry (RPLC-ESI-MS-MS). Extraction method was modified based on Folch method with optimally minimal level of ionization additive (ammonium formate 10 mM and formic acid). Reverse-phase liquid-chromatography was applied for chromatographical separation in combination with negative ionization mode electrospray-coupled Orbitrap mass spectrometry. The method validation was performed on human blood plasma in a non-targeted lipid profiling manner with full-scan MS mode and data-dependent MS/MS. The proposed method presented good inter-assay precision for primary targets, S1P and LPA. Subsequent analysis of other types of LPLs identified a broad range of lysophosphatidylcholines (LPCs) and lysophosphatidyl-ethanolamines (LPEs).

Purpose: The purpose of this study is to provide basic data for a more reasonable health teacher placement policy sending teachers to more appropriate sites, by analyzing the change process of the health teacher placement standards and the problems caused by an unreasonable placement policy. Methods: This study mainly analyzed relevant research data and existing studies focusing on a literature analysis. Results: To date, the placement policy for health teachers has changed, going through expansion, reduction, and retrogression, since its establishment. The standard, placing health teachers only in elementary schools with more than 18 classes, was created in 1952. Despite the expansion of the role of health teachers and the revision of the school health law in 2007, this standard has been applied to date without modification. In the meantime, there have been many problems caused by inappropriate placement of health teachers. It was difficult for health teachers in large schools to carry out proper health education; and, in many schools, passive health management, such as first aid, health tests, and student health management, was mainly executed rather than active health management. Students in small schools were not even given an opportunity to receive health education and health management owing to the absence of health teachers. Also, compared to teachers teaching other subjects, health teachers have had very unfair placement standards. Conclusion: The placement policy for health teachers, which has been applied to the present, has never reflected social change, the increase of student health issues, and the demand from the school area. Although the role of health teachers expanded with the execution of health education, the current placement standards for health teachers are very unreasonable. Accordingly, it is necessary to review the health teacher placement policy in a reasonable manner and to revise the standards considering the reality.

After the Se-wol ferry disaster in Korea, the safety issue was highly spotlighted in a number of media, and consequently the ministry of public safety and security was newly established under the public attention. In addition to this, a recent earthquake in Gyeonju suggested the training issues for public such as evacuation and public safety. Regarding the industry, one of significant reasons causing the accidents were inadequate training, in execution of safety manual or inexperienced first response. Although the engineering or scientific study provided a basis of the industry safety and health in Korea a study focusing on the safety and health education system should be highlighted in that the law is the only way to execute the policy. In this manner, the goal of current study was to compare the safety and health education system in Korea to other countries including America, England and Germany. Especially, the law for training method, contents, supervision and punishment was analyzed. Result showed (1) lack of a structured training course for educating safety and health education trainer, (2) no training system of safety and health education to public or workers, and (3) less specific law for supervision and punishment as compared to the America, England and Germany.

World Agriculture faces daunting challenges in feeding the growing population today. Reduction in arable land extent due to numerous reasons threatens achievement of food and nutritional security. Under this back ground, agricultural use of acidic soils, which account for approximately 40 % of the world arable lands is of utmost important. However, due to aluminum (Al) toxicity and low available phosphorous (P) content, crop production in acidic soils is restricted. Citrus, in this context, gains worldwide recognition as a crop adapted to harsh environments. The present paper reviewed Al toxicity and possible toxicity alleviation tactics in citrus. As reported for many other crops, inhibition of root elongation, photosynthesis and growth is experienced in citrus also due to Al toxicity. Focusing at toxicity alleviation, interaction between boron (B) and Al as well as phosphorus and Al has been discussed intensively. Al toxicity in citrus could be alleviated by P through increasing immobilization of Al in roots and P level in shoots rather than through increasing organic acid secretion, which has been widely reported in other crops. Boron-induced changes in Al speciation and/or sub-cellular compartmentation has also been suggested in amelioration of root inhibition in citrus. Despite the species-dependent manner of response to Al toxicity, many commercially important citrus species can be grown successfully in acidic soils, provided toxicity alleviation Agro-biological tactics such as addition of phosphorous fertilizers are used properly.

새로운 기술의 발달과 병행하는 정보이용환경의 급격한 변화는 정보원의 이용 및 정보서비스에 대한 새로운 고찰을 요구한다. 이용자 정보추구의 올바른 이해는 정보서비스의 향상에 핵심적인 역할을 하고 있으므로 변화하는 정보이용환경에 따라 이용자의 정보추구를 시기적절하게 새롭게 고찰할 필요가 있다. 많은 이전 연구들이 이용자 정보추구에 초점을 맞추고 있으나 의사들의 정보추구, 특히 진료정보 및 의학지식 추구를 동시에 대상으로 한 연구는 거의 없다. 이에 따라 본 연구는 진료와 의학연구를 동시에 수행하는 대학병원의 강사인 의사들의 정보추구행태를 탐구하는 것을 목적으로 하고 있다. 본 연구는 연세의료원 강사 12명을 대상으로 개방형 반구조화 형식의 심층 면접을 통하여 수집하였다. 면접 내용은 크게 연구 환경, 진료와 관련된 정보 추구 행태, 선호하는 정보원과 자료 유형, 검색과정과 만족도의 4가지 주제로 구성하였다. 응답 결과 연구 목적의 정보추구에 있어서는 PubMed를 통한 전자학술지 대한 신뢰도가 더 높았으나 진료 목적인 경우에는 인쇄형태의 교과서를 더 선호하는 것으로 나타났다. 이는 정보원에 대한 권위와 근거를 매우 중요시하는 의사들의 태도에서 그 원인을 찾을 수 있다.

Parametric design systems serve as powerful assistive tools in the design process by providing a flexible approach for the generation of a vast number of design alternatives. However, contemporary parametric design systems focus primarily on low-level engineering and structural forms, without an explicit means to also take into account high-level, cognitively motivated people-centred design goals. We present a precedent-based parametric design method that integrates people-centred design "precedents" rooted in empirical evidence directly within state of the art parametric design systems. As a use-case, we illustrate the general method in the context of an empirical study focusing on the multi-modal analysis of wayfinding behaviour in two large-scale healthcare environments. With this use-case, we demonstrate the manner in which: (1). a range of empirically established design precedents -e.g., pertaining to visibility and navigation- may be articulated as design constraints to be embedded directly within state of the art parametric design tools (e.g., Grasshopper); and (2). embedded design precedents lead to the (parametric) generation of a number of morphologies that satisfy people-centred design criteria (in this case, pertaining to wayfinding). Our research presents an exemplar for the integration of cognitively motivated design goals with parametric design-space exploration methods. We posit that this opens-up a range of technological challenges for the engineering and development of next-generation computer aided architecture design systems.
