Diffuse pollution has been considering as a major source of the quality deterioration of water resources. The establishment of riparian vegetation strips or buffers along those areas of water bodies is used to reduce the threat of diffuse pollution. Remote sensing offers a means by which critical areas could be identified, so that subsequent action toward the establishment of riparian zones can be taken. On the behalf of KOMPSAT-2 satellite imagery as a high resolution spatial data, Landsat TM satellite data are used to aquire the land cover for the riparian buffers studied. This investigation aims to assess the riparian buffers established on the upper Geum river as a pollution mitigation. Through comparing the delineation of riparian buffer zones developed with the existing zones established by the government, we can find the critical distortion points of the existing riparian buffer zone.

The importance of perceived quality and brand loyalty is increasing recently both domestic and foreign. So many papers perform research on service quality and brand loyalty. Today, there is the rapid growth in the Korean mobile telecommunications service market. But mobile telecommunications service companies don't pay full attention to customers' attitude and brand loyalty. This paper shows why Korean mobile telecommunications service companies have to focus on Brand Loyalty. This paper investigates the relationship among perceived quality, attitude and brand loyalty in the area of mobile telecommunications service.

Osteoporosis is the most common form of metabolic bone disease and is an important cause of morbidity and mortality in the elderly and especially in postmenopausal women. The possible beneficial action of essential fatty acids and their metabolites both in the prevention and treatment of osteoporosis needs attention. Therefore in this study, fatty acid levels of the normal groups was compared with those of patients. And then star symbol plots were drawn based on the fatty acids values of patients normalized to the corresponding normal group values to transform into visual patterns discriminating from the normal pattern.

The action of epigallocatechin-3-gi:lllale (EGCG). polyphenol compound from green lea, on the release pattern of glycosylphosphatidylinositol (GPI)-anchored renal dipeptidase (RDPase) from renal proximal tubules (PTs) was examined. EGCG had a stronger inhibitory effect on the release of RDPase than alkaline phosphatase (APase), another GPI-anchored ectoenzyme used as a reference protein. The effect of EGCG on cell viability as assessed by MTT test was found to be intact, and moreover, was indicative of potent cell activation or proliferation. (omitted)

Over the last 70 years, South Korea has gone through countless provocations from North Korea. Provocation is something that must be delicately calculated before the actual action, since it can be extended to a serious conflict. Among the possible factors, this paper focuses on the leader's characteristic, because 1) under North Korean dictatorship, the leader's thoughts are critical influence to policies and 2) personal characteristic, especially if it is the dictator's, hardly changes even when the external circumstances change. The purpose of this paper is in analyzing the correlations between North Korean leader's characteristics and provocation pattern. First, three generations of Kim Il-sung, Kim Jong-il, and Kim Jong-un's personal characteristics will be described. Next, particular provocation features in respective leader's period will follow. Lastly, how each leader's characteristic and concerns were reflected on the provocations will be analyzed.

In this study, the concept of autonomous mobility is applied to a gait support mobile robot. The aim of the development of the service robot is to assist the elderly with gait rehabilitation. This study proposes an ergonomic service robot design parameter. The gait assistant path pattern is derived from analysis of the elderly gait. A lever is installed in the AMR in order to measure both the pulling force and the leading force of the elderly. The path generation of the mobile robot is developed through consideration and analysis of elderly gait patterns. The ergonomic design parameters (dimensions, action scope and working space) are determined based on moving scope of the elderly. The gait assistant mobile robot was offered the elderly guide service and internet service based on the ergonomic design parameters.

Innate immunity is a first line defence system in the body which is for sensing signals of danger such as pathogenic microbes or host-derived signals of cellular stress. Pattern recognition receptors (PRR's), which present in the cell memebrane, are suspect the infection through pathogen-associated molecular patterns (PAMP), and activate innate immunity with response to promote inflammation via inflammatory cells such as macrophages and neutrophils, and cytokines. Inflammasome are protein complexes which are part of innate immunity in inflammation to remove pathogens and repair damaged tissues. What is the important role of inflammation in disease? In this review, we are focused on the action mechanism of NLRP3 inflammasome in inflammatory diseases such as asthma, atopic dermatitis, and sepsis.

근원섬유단백질의 생화학적 성질에 대하여서는 아직도 불명한 점이 많고, 특히 식품으로써의 근원섬유단백질의 저장 중의 변화에 대하여서는 규명되어야 할 점이 너무나 많다. 본 연구는 근원섬유단백질의 저장 중의 변화를 추구하기 위한 기초작업으로서 subcelular structure인 근원섬유를 재료로 하여 그 형태학적 측면과 생화학적 측면의 상관성을 비교 검토하였다. 근원섬유의 조제방법에 따라서 근원섬유의 근절(筋節)(sarcomere)의 길이는 변화하고 있었고 근절의 길이의 변화는 생화학적 성질. 즉 ATPase활성에 현저한 변화를 일으켰다. 근원섬유를 저농도의 trypsin으로 처리하면 근원섬유의 ATPase활성은 현저히 증가하나, 근원섬유의 위상차(位相差)현미경 상은 수축상태의 상을 나타내었다가 처리시간의 연장에 따라 sarcomere가 fragmentation을 나타냄을 보여주었다. 얻어진 결과로 근원섬유 중에는 ATPase활성을 저해하는 factor가 존재하며, 이 factor는 단백질의 inhibitory action은 아니고 steric effect임을 추정하였다. 또한 Z-line의 구성물질 중에 troponin의 관여가 추정되었다.

Backgrounds and objectives: POEMS (polyneuropathy, organomegaly, endocrinopathy, M protein, and skin changes) syndrome is the rare cause of polyneuropathy. Although the polyneuropathy is essential for the diagnosis of the disease, the pattern of electrodiagnostic abnormalities has not been characterized in detail. The purpose of this study was to elucidate the features of nerve conduction abnormalities in POEMS syndrome. Methods: We reviewed the medical records and nerve conduction studies (NCS) of 12 consecutive patients with POEMS. Results: A total of 68 motor and 46 sensory nerves were examined. Compound muscle action potentials (CMAPs) and sensory nerve action potentials were abnormally attenuated or not elicited in majority of motor and sensory nerves (80.88% in motor, and 82.6% in sensory nerves). Frequency of the nerves with no potential was significantly higher in lower limbs than in upper limbs (p<0.01 in both motor and sensory nerves), and CMAP amplitude was more reduced in lower limbs than in upper limbs (p<0.01). Conduction slowing was very frequently observed with 95% and 76% of motor and sensory nerves, respectively, having the abnormally reduced values of conduction velocity. Distal motor latencies were abnormally prolonged in 75% of motor nerves, and terminal latency indices were significantly higher in patients than in normal controls (p < 0.05). Conduction block was observed only in 5% of motor nerves. Conclusions: NCS in POEMS syndrome showed characteristic patterns, in which conduction abnormalities were more frequently and severely affected in the lower limbs, and more predominantly in the intermediate nerve segments than in the distal portions. The recognition of these characteristic patterns may be helpful in early diagnosis of polyneuropathy in POEMS syndrome.
