We report the results of the ionospheric measurement obtained from the instruments on board the Korea Multi-Purpose Satellite - 1 (KOMPSAT-l). We observed a deep electron density trough in the nighttime equatorial ionosphere during the great magnetic storm on 15 July 2000. We attribute the phenomena to the up-lifted F-layer caused by the enhanced eastward electric field, while the spacecraft passed underneath the layer. We also present the results of our statistical study on the equatorial plasma bubble formation. We confirm the previous results regarding its seasonal and longitudinal dependence. In addition, we obtain new statistical results of the bubble temperature variations. The whole data set of measurement for more than a year is compared with the International Reference Ionosphere (IRI). It is seen that the features of the electron density and temperature along the magnetic equator are more prominent in the KOMPSAT-l observations than in the IRI model.

이 연구는 간호대학생의 대인관계에 대한 어려움과 내재된 갈등 상황을 깊이 있게 이해하는데 그 목적이 있다. 이를 위해 대인관계 갈등을 경험했던 간호학과 학생 12명을 대상으로 2019년 7월부터 9월까지 내러티브 탐구절차를 수행하였다. 본 연구에서 간호 대학생들의 대인관계 갈등은 주로 학업 성적과 관련된 상황이 중심이었으며, 각종 이해 관계가 맞물린 학우들이 대상이었다. 또한 자아 중심의 ‘포커싱적 태도’가 특징으로 드러났다. 이러한 역기능적 대상관계가 중심이 되어 도출된 세부내용은 ‘대인 관계의 중심은 나’, ‘목적적인 관계’, ‘학업성취와 경제적 문제가 우선’, ‘온라인 관계에서 안정감을 느낌’, ‘이질적인 것에 배타적’, ‘남녀 간 경계와 애정문제’, ‘연대감 부족’이었다. 이 연구를 통해 간호대학생들은 새로운 관계맺음을 경험해 볼 수 있는 내러티브 과정을 경험하고, 긍정적 대인관계를 설계할 수 있는 기회를 맞이하였다. 더불어 연구자 또한 그들의 어려움을 이해하고 공감하여 학생들과 한층 가까워지는 경험의 장을 마련하였다. 추후 간호대학 생들에게 특화된 대인관계 중재를 통해 그 효과를 검증할 수 있는 연구가 후속되기를 제언하는 바이다.

This study started with the issue that the criteria for the general image scale used in outdoor color planning are vague and the vocabulary and expressive area of the scale are not accurate. As an exterior color planning guideline, it is required to suggest a sensible image scale, which is an appropriate assessment tool for outdoor environment. We identified psychological attributes of colors and set the color image scale axis as “Soft–Hard” in a vertical and “Warm–Cool” in a horizontal. 26 sensibility languages were finally selected for the image scale through literature review, pre-analysis, and expert evaluation. All types of colors extracted from analyzing over 600 photo images were categorized according to 26 sensibility languages. 3 colors by each sensibility language were finally selected and arranged in the color image scale in accord with the outdoor environment of the apartment houses. The significance of this study is that wide range of color position in the color image scale could be utilized as an effective guideline for actual color planning by upgrading the existing color image scale to a higher level with the color reflecting sensibility language. The result also implies that the development of diversified color palette is required especially for the exterior color planning of apartment houses, and the systematical color design process should be established in order to improve the quality of color environment.

Reuse, recycling and recovery (3R) of industrial wastes are common and encouraging in Korea. Industrial symbiosis is one of typical methods for implementing 3R and has been defined as engaging “traditionally separate industries in a collective approach to competitive advantage involving physical exchange of materials, energy, water, and by-products”. The keys to industrial symbiosis are collaboration and the synergistic possibilities offered by geographic proximity. Recently, several countries in East Asia such as Taiwan, South Korea, Japan and China are promoting ‘designed’ symbiosis networks in various industrial complexes based on their national Eco-industrial Park (EIP) demonstration programs. Despite the recently promoted EIP initiatives worldwide, only very few studies furnish the operational and functional details of ‘designed’ industrial symbiosis networks, starting from the planning to implementation stage. The production of terephthalic acid (TPA) in Korea is 6.5 million ton based on 2011. The production of waste generated in the process of TPA is about 15,000 ton/yr and included useful materials like residue TPA as well as isophthalic acid (iPA), benzoic acid (BA) and p-toluic acid (p-TL). Until now, TPA waste was incinerated due to high caloric value. This study was conducted for recovery of valuable materials from industrial waste and utilization of recovered material as an example of Korean EIP. In this study, the experiment was performed to separate above four materials from the waste by solvent (methanol and water) extraction. The solubility of TPA (0.1g/100g) for methanol is relatively low compared to other materials. Also the solubility of BA (68g/L at 95℃) and p-TL (11.6g/L at 98℃) for water is relatively high in comparison with other materials. Finally, BA was separated from p-TL by molecular distillation system. The purity of recovered materials was analyzed by ultra-high performance liquid chromatography (Waters Xevo TQ system). The recovery rate and purity of BA is 90% and 93%. The recovered BA could be recycled the companies which are produced plastic plasticizer and paints.

Genetic diversity of Korean landrace rice accessions was assessed with microsatellite markers. The 214 alleles weregedfrom 3 for SSS locus to 37 for RM206 locus with an average number of 12.6 alleles per locus. Gene diversity values according tothe 17 mic

This study focuses on the implications of the acceptability contrast of the locative inversion (LI) and presentational there insertion (PTI) constructions when considering some recent accounts of Extended Projection Principle (EPP) effects (see, among others, Chomsky 1995, 2000, Kim 2002, Lasnik 2001). For this purpose, we use Kim and Lee`s (to appear) acceptability judgment test composed of LI and PTI constructions, which was administered to native English speaking subjects. Results show judgment contrasts and confirm the slightly degraded nature of the LI constructions. In regard to the theoretical importance of the EPP, why perceptions of the contrasts differ is captured through a theoretical analysis.
